Evidence suggests the mental health impact on this clinical group was heterogeneous, but the role of ethnicity and socioeconomic position on longitudinal mental health outcomes is unclear. This systematic review investigates the longitudinal association between ethnic and socioeconomic inequalities and the mental health outcomes of CYP with pre-existing conditions during the pandemic. OVID Medline, EMBASE, APA PsycInfo, and Global Health databases were searched between January 2020 and November 2025 (PROSPERO CRD42024611865). Eligible papers included longitudinal studies that assessed mental health outcomes at multiple timepoints before and/or during the pandemic in CYP with pre-existing conditions and examined the effect of ethnicity and socioeconomic position on outcomes. Included studies were narratively synthesised. Ten studies (N = 3,887) were included. We found evidence that CYP from lower income brackets and who experienced financial hardship reported greater levels of internalising, neurodevelopmental, post-traumatic stress, and obsessive-compulsive symptoms. Weak associations were found between ethnicity and internalising symptoms. However, the findings were inconsistent across mental health outcomes, timepoints, and ethnic and socioeconomic position groups. There is some evidence for the association between lower socioeconomic position and increased mental health outcomes in CYP with pre-existing conditions during the pandemic. Further robust longitudinal research is warranted to examine the long-term consequences of the pandemic to better understand how ethnic and socioeconomic inequalities contribute to mental health outcomes.}, }

Unlike conventional small-molecule drugs or biologics, mRNA therapeutics exert their pharmacological effects indirectly by modulating intracellular protein expression and the immune system. However, the clinical demands that occurred during the COVID-19 pandemic rapidly accelerated mRNA therapeutics research and its clinical translation. Therefore, the present study examines how the COVID-19 pandemic reshaped global mRNA therapeutics research by comparing the pre-pandemic (2015-2019) and pandemic/post-pandemic (2020-2025) periods. A systematic analysis of peer-reviewed literature indexed in the Scopus database was conducted following PRISMA guidelines. The research activity increased markedly, with a nearly 13-fold rise in publications on mRNA therapeutics after the onset of the COVID-19 pandemic. Moreover, the analysis revealed a shift from oncology-oriented studies to vaccine-focused therapeutic research. The foundational studies on nucleoside-modified mRNA and lipid-based delivery systems aligned with large-scale clinical trial evidence. These trials validated the technology by demonstrating reproducible efficacy and acceptable safety profiles. Further, the collaboration patterns evolved from a predominantly US-centered structure to a globally interconnected research network led by the USA, China, and Germany. Overall, these findings provide quantitative evidence of significant shifts in global mRNA research activity and direction during the COVID-19 period.}, }

In several countries, they were listed as a priority group for receiving anti-SARS-CoV-2 vaccines when these vaccines were in scarce supply. These prophylactic vaccines do not completely prevent infections in vaccinated individuals, especially with a heterologous vaccine strain. However, they persistently reduce the severity of breakthrough infections, hospitalization rates and deaths. Although antiretroviral therapy (ART) suppresses HIV replication below the levels detectable by the assays used routinely in clinical care, it does not eliminate viral reservoirs; a small pool of infected cells carrying HIV proviruses integrated into the genomes of CD4[+] T cells and a subset of myeloid cells. Since vaccines work by stimulating these cells, they may theoretically reactivate latent HIV, increase plasma viremia and modulate the size of the HIV reservoir. The apprehension of HIV reactivation in PWH on ART prompted several studies in the past five years to investigate the impact of anti-SARS-CoV-2 vaccination on the markers of HIV persistence. Collectively, these studies have shown that the vaccination is generally safe in PWH on ART and induces only transient increases in viremia with no measurable impact on the size of the reservoir. However, in PWH with unsuppressed viremia, the vaccination was accompanied by more prolonged increases in viremia and in the frequencies of HIV-infected cells. In this review, we discuss these studies, their outcomes, their implications for HIV cure and propose topics for further research.}, }

Following Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) guidelines, we searched MEDLINE, Google Scholar, and Ichushi-Web through December 2025. Twenty-four studies from 12 countries were included. Workplace cyberbullying prevalence ranged from 1.5% to 46.6%. Across studies, digital harassment was reported in association with depression, anxiety, burnout, post-traumatic stress disorder (PTSD) symptoms, and moral injury-related experiences, although causal relationships could not be established. Seven included studies (28%) addressed pandemic-related digital harassment, including online abuse and stigmatization of healthcare workers during the COVID-19 period. Within the English- and Japanese-language literature identified in this review, Japanese studies were limited (three studies). From a consultation-liaison psychiatry perspective, harassment following ethically mandated actions may relate to moral injury-related experiences and may warrant further attention to institutional support. Evidence for effective interventions remains scarce. This review suggests that digital harassment may represent an emerging occupational concern with potential mental health implications. The evidence base was predominantly cross-sectional and methodologically heterogeneous, and findings should therefore be interpreted cautiously. Important needs include institutional policies, legal protections, psychological support systems, and further research on intervention effectiveness and cross-cultural patterns.}, }

Using an active-learning screening workflow with title/abstract screening, sensitivity checks and consensus adjudication, we identified 2,981 eligible studies published between 1988 and 2025 across 757 journals and 63 countries. Studies were coded by population (clinical vs. non-clinical), platform cluster, and author-reported PA outcome direction abstracted from the publication record.<br><br>RESULTS: Publications increased markedly after 2008, with smartphone/mHealth and wearable sensors becoming the dominant platform clusters in the 2010s and early 2020s. In the smoothed overall trajectories, publication activity reached its highest level around 2022, followed by a contraction concentrated mainly in mature clinical platform clusters. Non-clinical studies generally adopted newer platforms earlier, whereas clinical studies showed a recurrent lag before converging for more established, accessible technologies. A distinct population-level reversal was visible in mature platforms: non-clinical studies led early smartphone, wearable and web-based uptake, clinical studies became more prominent around the COVID-19 period, and non-clinical studies again predominated by 2025 for smartphone/mHealth, wearable sensors and web applications. Multi-component designs were common, with the strongest network backbone centred on smartphone, wearable and web-based combinations. Reported PA improvement signals were common across both population strata, but these findings reflect patterns in published study reporting rather than comparative effectiveness.<br><br>CONCLUSIONS: By providing a platform-centred, cross-population and temporally resolved map of technology-enabled PA interventions, this study identifies mature technology backbones, emerging areas of experimentation, and recurrent translational gaps between clinical and non-clinical contexts.

Emerging evidence indicates the existence of a lung-brain axis, through which pulmonary pathology and environmental exposures can influence neurological health. The current review highlights the mechanistic and clinical evidence linking chronic lung inflammation, air pollution, and immune dysregulation to the onset and progression of Alzheimer's disease (AD), Parkinson's disease (PD), Multiple sclerosis (MS), and amyotrophic lateral sclerosis (ALS). A pathway-based framework is presented in which lung inflammation, systemic cytokine release, oxidative stress, blood-brain barrier disruption, immune priming, and protein misfolding mediate lung-to-brain communication. Associations between chronic obstructive pulmonary disease, asthma, particulate matter exposure, and adverse neurological outcomes including cognitive decline, brain atrophy, disease progression, and elevated neurodegenerative risk are emphasized. Specific mechanisms are addressed, including immune-mediated effects in multiple sclerosis, inhalation-driven protein aggregation in Parkinson's disease, and vascular and oxidative injury contributing to dementia and amyotrophic lateral sclerosis. COVID-19 is considered a clinical model of acute lung-brain axis disruption, demonstrating inflammation-driven neurocognitive consequences, and its role in this context was also highlighted. Additionally, potential preventive and therapeutic strategies are discussed, highlighting pulmonary health and environmental exposure reduction as modifiable factors that may help mitigate neurological disease. This integrative review underscores the clinical relevance of the lung-brain axis and calls for interdisciplinary strategies to improve neurological outcomes through pulmonary and environmental interventions.}, }

Following an outbreak of the Zika virus, which has been linked to neurological issues in both adults and developing fetuses, we have recently dealt with SARS-CoV-2 infection, which has rapidly spread worldwide. Parasitic infections such as Malaria, Toxoplasmosis, and Chagas Disease severely affect the health of underresourced communities. In this scenario, the possibility of vertical transmission and fetal involvement is of significant concern. For protection, the fetus relies on the maternal immune system and placenta during intrauterine development. As an interposed organ between the mother and baby, the placenta performs numerous vital functions in fetal development, including multiple defense mechanisms against different types and intensities of stressors such as viral and parasitic infections. The role of the placenta in preventing pathogen access to the fetus and the factors involved in the failure of this mechanism need to be completely elucidated. In this scenario, syncytiotrophoblast plays a central role, using several strategies to prevent viral replication. Recent advances in the understanding of the molecular basis of these mechanisms include interferon (IFN) type I and III signaling, autophagy regulatory microRNAs, and the activation of the NF-κB pathway, which opens the possibility of cytokines and chemokines expression with local and systemic actions in the maternal organism. In this review, we address the role of the maternal-fetal barrier, chorionic villi in contact with maternal blood, antiviral and antiparasitic defense mechanisms, and mechanisms used by the human placenta against some of the most common viral and parasitic infections. Many of these strategies have successfully prevented congenital infections or fetal damage.}, }

The aim of this review was to analyze the execution of school feeding programs (SFPs) in Latin America in the context of the COVID-19 pandemic from the perspective of the Human Right to Adequate Food and Nutrition (HRAFN). We undertook a scoping review of articles and official documents in the databases Embase, FSTA, LILACS, PubMed, SciELO, Scopus, and Web of Science, and in official websites and websites of government agencies of Latin American countries. A descriptive synthesis of the data was performed from the perspective of the HRAFN, analyzing whether the availability, accessibility, adequacy, and stability dimensions were guaranteed. A total of 191 texts were located. From these, 107 were selected, including 20 articles and 87 documents. It was found that 3 of the 20 Latin American countries did not maintain SFPs during the pandemic (2020-2022): Cuba, Haiti, and Nicaragua. Most countries adapted the provision of school feeding to include food baskets, cash transfers, ready meals, or meals prepared at the educational institutions. Regarding accessibility, 45% of the countries served the same beneficiaries who were previously part of the program, while 30% reduced accessibility to only a portion of the public. As for adequacy, 55% of the countries did not specify whether fresh food was provided. Concerning the stability dimension, no texts presented information about the guarantee of the measures carried out regularly during the pandemic. The dimensions of the HRAFN were not fully contemplated during the emergency period, and, therefore, there were several violations of the rights of students who were beneficiaries of SFPs.}, }

This review examines the bidirectional relationship between disrupted gut microbiota and escalating AMR, particularly among vulnerable refugee populations and war-affected communities. Key findings reveal alarming resistance rates in ESKAPE pathogens (e.g., Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter spp), exacerbated by unregulated antibiotic use, malnutrition, and poor sanitation. Dysbiosis fosters AMR through loss of colonization resistance and horizontal gene transfer, while conflict-related healthcare breakdowns—such as empiric antibiotic overuse and absent diagnostics—accelerate resistance spread. Refugee camps, with overcrowding and contaminated water, emerge as critical AMR hotspots. Urgent interventions are needed, including microbiome restoration therapies (e.g., probiotics and faecal microbiota transplantation (FMT), rapid diagnostic tools, and integrated One Health surveillance. Moreover, the increasing trend of AMR is further amplified by the COVID-19 pandemic, which led to widespread antibiotic use and disrupted healthcare services. Review emphasises the importance of regional policy coordination, targeted humanitarian aid focused on microbiome health, and global advocacy to mitigate this crisis, which poses a threat to both local and international health security. Without action, the intersection of dysbiosis and AMR will deepen health inequities in conflict zones, with far-reaching consequences.}, }

We draw on the COVID-19 pandemic-a salient, prolonged event that stimulated widespread negative emotions-as a theoretically meaningful context to explore when and why negative emotions may yield beneficial outcomes. Specifically, we provide an integrative conceptual review synthesizing research from applied and social psychology conducted during the pandemic that identifies two pathways through which negative emotions produce functional individual-level outcomes at work. The first pathway captures direct effects driven by the unique action tendencies associated with discrete negative emotions. The second pathway, informed by the personality systems interaction theory, highlights contingent effects shaped by self-regulatory factors and external support from leaders, teams, or organizational policies. Our findings challenge and extend discrete emotion and affective shift theories by detailing how and under what conditions negative emotions from disruptive events can have functional outcomes. We bring necessary nuance to prevailing emotion theories and offer practical implications for leaders and organizations seeking to manage negative emotions during the times of hardship.

This scoping review synthesizes the most promising uses of AI in respiratory medicine, with a particular focus on pulmonologists and family physicians interested in lung health. In diagnostics, deep-learning systems streamline chest-imaging workflows by triaging radiographs, detecting COVID-19 pneumonia, and classifying lung nodules on CT. In pulmonary function testing, algorithms detect technical errors and classify spirometric patterns, some claiming to outperforming pulmonologists. Acoustic analysis of cough, breathing, and speech captured on smartphones or wearables offers non-invasive decision support. For monitoring and prediction, AI helps shorten weaning from mechanical ventilation and guides closed-loop strategies for acute respiratory distress. In chronic care, connected devices integrated with environmental data help to forecast asthma and COPD exacerbations, while telehealth and predictive models enable earlier, more personalized interventions. Additional gains are emerging in paediatrics, sleep medicine, lung ultrasounds, and public health. Realizing these benefits will require rigorous multicentre validation and real-world evidence. It will also require proactive bias detection and mitigation with inclusive sampling and equity audits. High-quality, interoperable data and explainable models are needed to enable human oversight. Practical issues such as digital literacy, device access, and usability for children, older adults, and other vulnerable populations also matter for applications requiring patient interaction. With sustained collaboration among clinicians, engineers, AI experts, industry, regulators, and scientific societies, AI can increase the time invested in a satisfactory clinician-patient relationship. With all likelihood, AI can also measurably improve efficiency and accuracy across multiple domains of respiratory care.}, }

Analyzed were conducted across study characteristics, shocks/stressors types, conceptualizations/definitions, framework traditions, and methodological approaches.<br><br>RESULTS: A total of 125 empirical studies were included, with a marked increase from 2020 onward. Most studies examined acute shocks (84%), with the largest share in the Europe (23.3%) and Africa (16.8%). HSR was predominantly conceptualized as a system capacity to absorb and adapt to shocks, while learning and transformation were less frequently operationalized. Health system-specific frameworks (e.g., Kruk; Blanchet) were most commonly used, primarily as analytical lenses rather than measurement tools. Qualitative methods predominated, although mixed-methods approaches are emerging. Evidence on continuity of essential functions and everyday resilience remained limited.<br><br>CONCLUSIONS: Despite growing conceptual sophistication, empirical HSR research remains constrained by fragmented frameworks use and limited operationalization. Advancing the field requires clearer conceptual boundaries, improved methodological integration, and greater attention to how resilience is enacted in routine system functioning.}, }

Nonetheless, disease prognosis is contingent upon multiple factors. mRNA and other small RNAs are essential for gene regulation and disease progression. Additionally, they are essential for the advancement of TB mRNA therapies. The review aims to evaluate the functions of mRNA and various small RNAs, including lncRNA, miRNA, circRNA, and ceRNA, as interconnected components within the mRNA-miRNA-circRNA axis in Mycobacterium tuberculosis. In this context, the analysis of various genes expressed during transcription is essential; however, the TB group’s mRNA expression levels of the CXCL10, CXCL9, IL1B, and PLA2G2D genes were substantially higher compared to the control group. In addition, EspC, MetE, and PPE15 increased IgG levels. Besides, the inadequate IgG responses to m-ESAT6 and m-EsxI present a noteworthy research opportunity. Evidence that neutralizing antibodies provide protection against viral infections targeted by mRNA vaccines during the COVID-19 pandemic supports this research. mRNA-based vaccination analogues offer potential therapeutic advantages following BCG administration. Mycobacterium avium and Mycobacterium tuberculosis are efficiently inhibited by the mRNA therapy, namely the repRNA-ID91/ID91 + GLA-SE vaccination, which elicits humoral and cellular immune responses. Therefore, the therapeutic use of mRNA, as demonstrated by numerous studies, suggests its potential as an efficacious therapeutic vaccine subsequent to BCG treatment. Also, investigating the ceRNA network and the relationships among miRNA, circRNA, lncRNA, and mRNA in TB study will improve the management of this infection.}, }

Three databases, namely, Web of Science, PubMed, and CINAHL, were searched for studies published between 1 March 2014 and 1 March 2024. Fifty-three eligible studies were included. Data were extracted from nine dimensions and synthesized to address four research questions: conceptual orientations, research gaps, research pathways, and website selection methods. The data synthesis revealed that: (i) research gaps exist, particularly with COVID-19 as the predominant health topic; (ii) the reviewed studies were geographically focused on only 12 regions, with the United States receiving the most extensive attention (54.5%); (iii) only 16 studies (30.2%) specifically targeted immigrants or ethnic minorities; (iv) only five different languages appeared as source languages of the studied websites, and 86.8% of studies focused on websites originally prepared in English; and (v) common criteria for evaluating multilingual accessibility included the presence of multilingual options, languages offered, translation methods, and the quantity of multilingual information. This review offers insights into the research gaps and methodologies for evaluating the multilingual accessibility of health websites. Future studies could focus on empirical research across diverse health websites, regions, and language pairs.

Despite its prevalence, the pathophysiology of PASC remains poorly understood. This narrative review highlights activation of mast cells (MCs), the unique tissue immune cells as a central contributor to neuropathic manifestations in PASC. Mast cell locations near nerves and vessels allows them to regulate neuroimmune and neurovascular processes. Mast cell activation mirrors patterns seen in small-fiber neuropathy and myalgic encephalomyelitis/chronic fatigue syndrome, suggesting a shared immune-mediated etiology. The SARS-CoV-2 spike protein has been shown to activate MCs via angiotensin-converting enzyme 2 and toll-like receptor 4, triggering release of pro-inflammatory and neurotoxic mediators, including interleukin-1β, interleukin-6, tumor necrosis factor alpha, histamine, and tryptase. Such mediators sensitize peripheral nerves, disrupt the blood-brain barrier, and recruit microglia, ultimately contributing to small-fiber injury, neuroinflammation, and dysautonomia. Emerging reports suggest benefit from MC-directed treatments although responses remain variable. Understanding the role of MCs in PASC may offer a plausible mechanism of pathogenesis and guide targeted therapies. Future studies are needed to validate these findings and improve PASC patient outcomes.}, }

We reviewed existing literature on placebo effects in neuromodulation, technical challenges of sham tSCS implementation, and ethical considerations specific to the SCI population. Alternative methodological approaches were evaluated, including sequential self-controlled designs, biomarker-guided approaches, and adaptive trial designs.<br><br>RESULTS: Traditional sham controls for tSCS face serious technical challenges because participants readily detect stimulation parameters, minimal currents produce detectable neuromodulatory effects, and extended protocols amplify these issues through knowledge sharing and functional feedback. Ethical concerns include substantial participant burden, potential for lessebo effects when a sham is suspected, and erosion of therapeutic relationships through prolonged deception. The COVID-19 pandemic added critical safety considerations for the vulnerable SCI population. Alternative designs, such as sequential self-controlled approaches, as implemented in Up-LIFT, can maintain scientific validity while addressing these constraints.<br><br>CONCLUSION: The unique challenges of tSCS clinical trials necessitate innovative methodological approaches beyond traditional placebo-controlled designs.

In recent years, the role of the glycocalyx in the pathophysiological processes of various diseases, such as cardiovascular diseases, chronic kidney disease, sepsis, COVID-19 infection, and diabetes, has gradually attracted widespread attention, and its importance has been increasingly recognized. In these acute and chronic clinical situations, the endothelium surface may lose syndecans, heparan sulfate (HS), and hyaluronan (HA), the primary constituents of the glycocalyx, a process involving multiple degrading enzymes. This review aims to start from the mechanisms of glycocalyx degradation, systematically elaborate on the factors related to degradation, enzymes involved in the degradation process, and signaling pathways. It also explores pharmacological drugs with the potential to reduce glycocalyx shedding, as found in current laboratory and clinical studies.

Traditional antiviral drugs and vaccines are often limited by viral mutations, drug resistance, and inter-individual variability. The human microbiota has emerged as an active regulator of viral pathogenesis, influencing host susceptibility, immune responses, and therapeutic outcomes. This review comprehensively explores microbiota–virus interactions, including direct viral modulation by commensal bacteria and bacteriophages, metabolic reprogramming of host cells, and immunomodulation by microbial metabolites such as short-chain fatty acids (SCFAs) through the GPR43–NLRP3–MAVS axis. The gut–lung–immune axis and systemic consequences of virus-induced dysbiosis, including “leaky gut” and amplified cytokine responses (TNF-α, IL-6), are highlighted. Translational applications discussed include probiotics, prebiotics, postbiotics, fecal microbiota transplantation (FMT), and next-generation engineered microbial consortia. Evidence from clinical FMT trials in chronic hepatitis B, liver cirrhosis, and COVID-19 recovery, along with FDA-approved oral microbiota therapies, suggests therapeutic promise. The integration of AI-guided multi-omics approaches enables patient stratification and personalized interventions while addressing safety, strain specificity, and regulatory challenges. This review integrates mechanistic insights and clinical evidence to guide the development of next-generation microbiota-based precision antiviral therapies with improved efficacy and durability.}, }

Perceived discrimination is a key factor, exacerbated by recent global events such as COVID-19. However, much of the literature aggregates immigrants of different Asian ethnicities and generational statuses, despite documented disparities in mental health outcomes. This review aims to address this gap in literature by systematically reviewing empirical studies that explore the relationship between perceived discrimination and mental health outcomes of first-generation immigrants from East Asia only. METHODS: This review was registered on the PROSPERO international registry for systematic review protocols (Registration Number: CRD42024505188). Five databases (Embase, PsycINFO, Medline, Web of Science and Scopus) were searched for quantitative, English-language studies that explored the relationship between perceived discrimination and validated measures of mental health outcomes among first-generation East Asian immigrants. Studies were appraised for methodological quality using The Joanna Briggs Institute (JBI) Critical Appraisal Checklist for Analytical Cross-Sectional Studies tool [1]. Findings were synthesised narratively due to heterogeneity in methodology across studies. RESULTS: Out of 1,061 screened articles, 10 studies met the inclusion criteria. All included studies explored perceived discrimination, through racial discrimination. Only studies of Korean or Chinese first-generation immigrants were found. Ten studies reported a significant association between perceived racial discrimination and poorer mental health outcomes, particularly depressive symptoms. A range of variables that influenced this relationship were also identified, with degree of social support emerging as a consistent factor. Methodological limitations included inconsistent control for relevant sociodemographic or immigrant-related variables and differences in in exclusion or inclusion criteria used in the different studies. CONCLUSION: Overall, the findings highlight that experiences of perceived racial discrimination have a detrimental impact on the mental health of first-generation Korean and Chinese immigrants. However, inconsistencies in the measurement and study design presented challenges for synthesising the results and drawing firm conclusions, particularly regarding the role of influencing variables. Future research should use more consistent measures of perceived discrimination and mental health to better quantify the outcomes and understand the mental health implications. Research should also continue to disaggregate data by both generational status and specific East Asian ethnic groups, particularly those underrepresented in the current review, such as Japanese, Taiwanese, and Mongolian immigrants.}, }

Unlike traditional vaccines that rely on live-attenuated or inactivated pathogens, mRNA vaccines use synthetic mRNA encoding the antigen, allowing host cells to produce the antigen and elicit strong immune responses. The success of mRNA vaccines against Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has gradually increased global curiosity in applying this technology to treat other diseases. This review discusses the scientific basis of mRNA vaccines, including their mechanism of action, advantages in antigen design, expandable manufacturing, and modern delivery systems such as organic, inorganic, and hybrid. Beyond COVID-19, mRNA vaccines are being studied for other viral diseases, including influenza, Human Immunodeficiency Virus (HIV), Zika, and dengue. The intrinsic flexibility and speed of mRNA technology make it a valuable platform for next-generation pandemic preparedness and new therapeutic development. Despite these advantages, many challenges exist, including mRNA instability, cold-chain storage requirements, regulatory issues, and concerns regarding global vaccine availability and acceptance. Overcoming these will be critical for the full long-term potential of mRNA vaccines as a sustainable and transformative platform for global health.

Hypocalcemia is common in Coronavirus Disease 2019 (COVID-19), yet the insufficient compensatory rise in parathyroid hormone (PTH) and its long-term outcomes remain poorly characterized. We describe a young adult Chinese woman with no history of neck surgery who developed severe symptomatic hypocalcemia shortly after acute SARS-CoV-2 infection. Laboratory evaluation revealed inappropriately low PTH levels with concomitant hyperphosphatemia, consistent with hypoparathyroidism (HypoPT). Although baseline calcium/PTH data prior to infection were unavailable, the regular calcium and vitamin D supplementation, along with serial monitoring over more than two years, demonstrated persistently suppressed PTH secretion, supporting a diagnosis of permanent HypoPT. Thyroid imaging and antibody testing confirmed coexistent Hashimoto's thyroiditis, raising the possibility of an autoimmune contribution. To contextualize this case, we reviewed 14 previously published reports of COVID-19-associated HypoPT, among which no cases originating from China were identified. Based on available data, it cannot be ruled out that SARS-CoV-2 infection may contribute to the development of new-onset HypoPT in addition to worsening pre-existing conditions. Young-onset patients without a history of surgery-particularly those whose hypocalcemia severity does not clearly parallel the severity of infection-appear to have a higher likelihood of subsequent persistent dysfunction, though this observation remains preliminary. This case, together with the literature, underscores the need for extended follow-up in patients presenting with hypocalcemia and blunted PTH responses after COVID-19. Comprehensive autoimmune evaluation and, where appropriate, genetic testing should be considered to clarify etiology and guide long-term management.}, }

Vaccination was found to significantly modify the disease trajectory, offering protection against subsequent gastrointestinal sequelae and preserving pulmonary function by mitigating small airway resistance. Furthermore, advanced diagnostic modalities, including impulse oscillometry and deep learning-assisted echocardiography, successfully unmasked subclinical organ dysfunction that conventional methods often failed to detect. Mechanistic investigations revealed that symptom severity was closely linked to elevated anti-nucleocapsid antibody titers, while markers of T-cell exhaustion evidenced persistent immune dysregulation, rather than ongoing viral replication. Notably, a preliminary single-center randomized controlled trial within this cohort provided early evidence that vitamin D supplementation may reduce the overall symptom burden and modulate pro-inflammatory cytokine profiles in children with PASC. Collectively, these findings underscore the multisystem nature and immune-driven mechanism of pediatric PASC, while highlighting the role of vaccination, advanced diagnostics, and targeted nutritional interventions in improving recovery.

Notably, the recent outbreak of the recombinant feline coronavirus (FCoV-23) and the persistence of SARS-CoV-2 variants underscore the urgent need to understand viral pathogenesis and cross-species transmission mechanisms. Reverse genetics technology serves as a critical platform for bridging genomic sequencing to functional virology, enabling targeted mutagenesis and the generation of recombinant viruses. However, the construction of reverse genetics systems for coronaviruses is often hampered by their exceptionally large genomes and the instability of viral cDNA sequences in bacterial hosts due to cytotoxicity. This review moves beyond a simple enumeration of methods to systematically compare current reverse genetics strategies-including in vitro ligation, bacterial artificial chromosome (BAC) systems, and transformation-associated recombination (TAR)-across different viral genera. Furthermore, we critically evaluate the application of these platforms in deciphering pathogenic mechanisms and developing next-generation vaccines, with a specific focus on overcoming technical bottlenecks and designing broad-spectrum countermeasures against emerging cross-species threats.}, }

This systematic review describes the clinical manifestations and laboratory findings reported in patients coinfected with DENV and SARS-CoV-2.<br><br>METHODS: This review followed the PRISMA guidelines and collecting data from PubMed for articles published between 2020 and 2025 that discussed DENV and SARS-CoV-2 coinfection. Eligible study designs included theoretical articles, case reports, case series, and cohort studies. Data were synthesized descriptively due to heterogeneity and the absence of comparator groups.<br><br>RESULTS: Fifteen studies met the inclusion criteria, identifying 65 patients with SARS-CoV-2 and DENV coinfection. Reported symptoms included fever (69%), vomiting (57%), abdominal pain (55%), rash (54%), and shock (51%). Laboratory findings also showed hematological and physiological alterations including hypotension (57.14%), tachypnea (50%), fever (62.5%), neutropenia (33.33%), neutrophilia (50%), lymphopenia (42.86%), and lymphocytosis (28.57%).

Despite their expanding roles in meat and milk production, transport, tourism and racing, camel health and welfare remain comparatively underexplored, particularly regarding infectious diseases. This review synthesizes current knowledge on major bacterial infections, including brucellosis, tuberculosis, mastitis, suppurative infections, salmonellosis, and clostridial diseases, as well as important viral diseases such as Middle East respiratory syndrome coronavirus, camel pox, Rift Valley fever, rabies, contagious ecthyma, and peste des petits ruminants, with a focus on their implications for animal welfare. These diseases commonly lead to acute and chronic pain, fever, respiratory compromise, reproductive failure, debilitation, and mortality, and are associated with physiological stress responses such as activation of the hypothalamic-pituitary-adrenal axis and increased acute-phase proteins, alongside behavioral changes including lethargy, reduced grooming, altered social interactions, and impaired maternal and working behaviors. Using the Five Freedoms and the Five Domains Model frameworks, this review demonstrates how infectious diseases undermine multiple dimensions of camel welfare, including nutrition, physical comfort, health, behavior, and mental state. Beyond individual animals, camel diseases have significant socioeconomic and ethical implications. Several pathogens are zoonotic, posing risks to pastoralists, veterinarians, and other stakeholders, and influencing trade regulations, disease control strategies, and culling practices, which may further exacerbate welfare compromise. Key knowledge gaps remain, including the lack of validated camel-specific welfare assessment tools, limited longitudinal data on welfare trajectories during disease outbreaks, and insufficient integration of welfare indicators into surveillance and control programs. The review highlights priority research and policy needs, including the development of field-adapted welfare scoring systems, evaluation of welfare impacts of interventions such as vaccination and movement restrictions, and stronger integration of animal welfare into One Health and One Welfare frameworks to support sustainable camel production and resilient dryland livelihoods.}, }

This meta-analysis aimed to determine the impact of nirmatrelvir/ritonavir on the outcomes of immunocompetent patients with confirmed Omicron variant. Three reviewers systemically searched PubMed (Medline), Cochrane Library, and Embase databases up to June 9, 2025. Randomized clinical trials (RCTs) and observational studies with a control group were screened for eligibility to extract data.

Forty-six observational studies, including 6,099,805 participants, were involved in the meta-analysis. Our findings revealed that nirmatrelvir/ritonavir significantly decreases death (risk ratio [RR] =0.31; 95% confidence interval [CI]: 0.23-0.40), disease progression (RR = 0.57; 95% CI: 0.42-0.71), hospitalization (RR = 0.45; 95% CI: 0.35-0.56), composite outcome of hospitalization and death (RR = 0.58; 95% CI: 0.44-0.71), ventilation (RR = 0.46; 95% CI: 0.19-0.72), and intensive care unit admission (RR = 0.56; 95% CI: 0.38-0.73) compared to the control group. However, no significant difference was shown across the two groups regarding hospitalization duration (mean difference = -2.34; 95% CI: -5.60-0.93).

IPD analysis revealed an impairment in global longitudinal strain (GLS) (mean difference (MD) = 3.63 %) in individuals with PASC. When using categorical thresholds, 58 % of individuals with PASC had GLS < 16 %, indicating a significant prevalence of subclinical left ventricular dysfunction. Meta-analysis supported these findings, showing impaired GLS (MD = 1.07 %), along with reductions in left ventricular ejection fraction (MD = -1.30 %) and left ventricular end-diastolic volume (MD=-3.98 mL). Meta-regression showed that cardiac dysfunction was more frequently observed in individuals with older age, diabetes, and hypertension.<br><br>CONCLUSION: This review indicates that PASC is associated with modest, subclinical alterations in cardiac function. These alterations appear more pronounced in older adults and those with cardiometabolic comorbidities, highlighting the potential value of risk-stratified cardiovascular surveillance in individuals with PASC. The long-term clinical relevance of these changes remains unclear and warrants further study.}, }

This review critically synthesizes the current biomarker landscape and proposes an integrative framework to address the significant translational gaps between biomarker science and clinical practice. We conducted a comprehensive critical review, analyzing established and emerging biomarkers, including cardiac troponins, natriuretic peptides, and inflammatory and fibrotic markers, within the context of biological confounders, etiology-specific challenges, and clinical implementation barriers. Through thematic synthesis, we developed the novel C.A.L.I.B.R.A.T.E. framework to structure biomarker integration. While high-sensitivity assays have improved detection, they reveal chronic elevations in conditions like renal dysfunction, aging, and heart failure, reducing specificity and complicating acute diagnosis. Emerging biomarkers (eg, sST2, galectin-3) offer prognostic insight but lack therapeutic guidance and specificity. Etiology-specific puzzles (eg, myocarditis, COVID-19, MINOCA) highlight the limitations of isolated biomarker interpretation. The C.A.L.I.B.R.A.T.E. framework addresses these gaps by integrating Clinical context, Assay characteristics, Likelihood, Injury mechanism, Biomarker profiles, Rule-out/in thresholds, Adjunctive tests, Time kinetics, and Etiologies &amp; comorbidities. The future of myocardial injury management depends on shifting from isolated biomarker measurement to integrated, algorithm-driven interpretation. The C.A.L.I.B.R.A.T.E. framework provides a structured pathway for personalized diagnostic reasoning, bridging the translational chasm and advancing precision cardiology through context-dependent, multi-modal data synthesis.}, }

We searched MEDLINE/PubMed for all randomized controlled trials published in five high-impact general medicine journals: Annals of Internal Medicine, the British Medical Journal (BMJ), the Journal of the American Medical Association (JAMA), the Lancet, and the New England Journal of Medicine (NEJM). Our search spanned a 10-year period from 2014 to 2023, which included data from before and after the emergence of the COVID-19 global pandemic. We performed single-author data extraction via abstract review to determine study positivity, defined as statistical significance for the primary outcome, flagging abstracts for secondary review if positivity was not clear. Two authors reviewed all flagged abstracts. We calculated the proportion of negative studies (i.e., not meeting statistical significance for the primary outcome) overall, by journal, and by publication year. We used logistic regression to model the odds of a study reporting a negative result by journal and year. Our search yielded 3722 individual citations, with screening resulting in 3600 randomized controlled trials for review, with 31% of studies reporting negative results. The proportion of negative studies varied, ranging from 22% in the Lancet to 51% in BMJ and JAMA. The proportion of negative studies remained consistent over time. High-impact general medical journals vary widely in the percentage of negative studies that they publish but did not change over time, even during and after a global pandemic. Further study is needed to determine factors influencing this phenomenon and what can be done to minimize publication bias.}, }

Emerging omics-based studies propose that prior SARS-CoV-2 exposure may shape a distinct dengue phenotype through immune imprinting and antibody-dependent mechanisms. However, whether these molecular signals translate into clinically meaningful outcomes remains unclear. This Perspective argues that current evidence remains preliminary and insufficient for clinically actionable interpretation, particularly regarding the conflation of group-level proteomic signals with patient-level clinical phenotypes. Using a recent pilot proteomic study as an illustrative example, we highlight key methodological constraints, including pooled sampling, limited sample size, inadequate control of confounding, and absence of longitudinal and clinical validation. We propose a framework for advancing from exploratory omics observations to clinically interpretable evidence, emphasizing patient-level resolution, temporal dynamics, statistical rigor, functional validation, and integration with standardized clinical endpoints. We also examine the clinical and public health consequences of premature inference, including the potential for premature clinical interpretation, overestimation of disease associations, and challenges in translational interpretation. We conclude that proteomic signals should be regarded as hypothesis-generating rather than predictive until supported by robust, reproducible, and clinically anchored evidence.}, }

The pooled prevalence of fatigue was 55% (95% CI 46-65%, k&#x2009;=&#x2009;32). Mental fatigue was reported by 58% (95% CI 17-90%, k&#x2009;=&#x2009;4), while 53% (95% CI 38-67%, k&#x2009;=&#x2009;11) experienced fatigue related to PPE use. No significant differences were observed between doctors and nurses (P&#x2009;=&#x2009;0.327) or frontline and non-frontline staff (P&#x2009;=&#x2009;0.103). Risk factors included stress, anxiety, depressive symptoms, workload and extended working hours, while resilience, self-efficacy and sufficient rest were protective. Substantial heterogeneity (I2 &#x223c;99%) and reliance on cross-sectional designs limited causal inference.<br><br>CONCLUSIONS: Our study indicated that over half of HCW reported fatigue and highlighted its multifactorial nature. Organizational-level interventions, such as optimized shift patterns, mandated rest breaks and psychological support are essential to mitigate fatigue, safeguard wellbeing and ensure safe healthcare provision.}, }

This systematic review and meta-analysis aimed to determine the pooled prevalence of depression among Indian T2DM patients, highlight regional differences, and identify associated risk factors.<br><br>METHODS: Following PRISMA guidelines, a thorough search was conducted across PubMed, Embase, Scopus, and Web of Science for studies published until February 3, 2025. Random-effects models were applied to calculate pooled prevalence, while subgroup analyses assessed variations by geographic region, diagnostic tool, and study setting. Heterogeneity was quantified using I&#xb2; statistics. Publication bias was evaluated using funnel plots and Egger&#x2019;s regression, with trim-and-fill analysis performed when bias was detected. Meta-regression examined the impact of covariates such as sample size, mean age, diabetes duration, hypertension, and urban residence.<br><br>RESULTS: A total of 59 studies with 24,073 participants were included. The pooled prevalence of depression among T2DM patients was 38% (95% CI: 33&#x2013;42%), derived using a random-effects model to account for the substantial heterogeneity observed across studies (I&#xb2; = 98.28%). This estimate reflects a statistical synthesis across studies with widely varying diagnostic tools, cutoff thresholds, and clinical settings, and should be interpreted as an approximation of the burden rather than a precise national prevalence figure. Mild, moderate, and severe depression accounted for 24%, 14%, and 14% of cases respectively. Regional variation was observed, with Western India showing the highest prevalence (48%) and multicenter studies the lowest (27%). Prevalence differed by diagnostic tool: CIDI-SF (20%), PHQ-9 (34%), and BDI (72% with lenient cutoffs). Hospital-based studies reported higher prevalence (42%) compared to community-based ones (28%). Females had a greater burden (39%) than males (31%). No significant differences were found between pre- and post-COVID-19 studies. Sensitivity analyses confirmed robustness of estimates. Meta-regression identified diabetes duration as a significant predictor (p&#x2009;=&#x2009;0.026).<br><br>CONCLUSION: Nearly two in five Indian T2DM patients experience depression, emphasizing the urgent need for standardized screening and integration of mental health care into India&#x2019;s National Program for Non-Communicable Diseases.<br><br>SUPPLEMENTARY INFORMATION: The online version contains supplementary material available at 10.1186/s13098-026-02160-w.}, }

These improvements have been largely confined to older populations, while the burden of cardiometabolic risk remains high. The Greek cardiovascular landscape has also evolved under the combined influence of population aging, the COVID-19 pandemic, persistent socioeconomic pressures, and increasingly stringent European Society of Cardiology targets for lipid and blood pressure control. Traditional determinants, particularly dyslipidemia, hypertension, diabetes, obesity, unhealthy dietary patterns, smoking, and physical inactivity, remain prevalent and frequently suboptimally controlled. Against this background, residual risk and emerging determinants of disease are increasingly recognized as clinically relevant contributors to cardiovascular burden. This narrative review summarizes recent evidence on the role of non-traditional risk factors in the Greek population, including lipoprotein(a), inflammation, metabolic dysfunction-associated steatotic liver disease, chronic kidney disease, chronic obstructive pulmonary disease, sleep disturbances, infections and vaccination, environmental exposures, mental health, and social determinants of health. Overall, the available evidence supports a broader cardiovascular prevention framework that extends beyond conventional risk-factor assessment. Integrating selected non-traditional determinants into clinical practice and prevention policy may improve risk stratification, support individualized care, and help address the evolving cardiovascular burden in Greece.}, }

Vesicular eruptions appear early in the course of the disease (15% before other symptoms). The pseudo-chilblain pattern frequently appears late in the evolution of the COVID-19 disease (59% after other symptoms), while the rest tend to appear with other symptoms of COVID-19. The severity of COVID-19 shows a gradient from less severe disease in acral lesions to more severe in the latter groups. The results are similar for confirmed and suspected cases, in terms of both clinical and epidemiological findings. Alternative diagnoses are discussed but seem unlikely for the most specific patterns (pseudo-chilblain and vesicular).<br><br>CONCLUSIONS: We provide a description of the cutaneous manifestations associated with COVID-19 infection. These may help clinicians approach patients with the disease and recognize cases presenting with few symptoms. What is already known about this topic? Previous descriptions of cutaneous manifestations of COVID-19 were case reports and mostly lacked illustrations. What does this study add? We describe a large, representative sample of patients with unexplained skin manifestations and a diagnosis of COVID-19, using a consensus method to define morphological patterns associated with COVID-19.

Focusing on the available literature and personal clinical expertise, an Italian board of nine professionals from different disciplines identified four main topics: prevention of chronic pain, treatment of chronic pain, consequences of inadequate treatment, and perspectives. They elaborated a semi-structured questionnaire. A multidisciplinary panel of experts in the field of pain management was requested to comment on the statements. Based on the answers provided, a structured questionnaire was prepared (Round 1). It included 21 statements divided into three categories (organizational issues; diagnosis and therapies; telemedicine and future perspectives). A five-point Likert scale was adopted. The threshold for consensus was set at a minimum of 70% of the number of respondents (level of agreement ≥ 4, Agree or Strongly Agree). A final questionnaire with rephrasing of the statements that did not reach the consensus threshold was elaborated (Round 2). A total of 29 clinicians were included in the panel. Twenty clinicians (69%) responded in both the first and second round. After two rounds, consensus (≥70%) was achieved in 20 out of 21 statements.

We aimed to produce a list of priority areas for cancer research in countries with limited resources, informed by researchers and patients.<br><br>METHODS: Cancer experts in lower-resource health care systems (as defined by the World Bank as low- and middle-income countries; N = 151) were contacted to participate in a modified consensus-seeking Delphi survey, comprising two rounds. In round 1, participants (n = 69) rated predetermined areas of potential research priority (ARPs) for importance and suggested missing ARPs. In round 2, the same participants (n = 49) rated an integrated list of predetermined and suggested ARPs from round 1, then undertook a forced choice priority ranking exercise. Composite voting scores (T-scores) were used to rank the ARPs. Importance ratings were summarized descriptively. Findings were discussed with international patient advocacy organization representatives.<br><br>RESULTS: The top ARP was research into strategies adapting guidelines or treatment strategies in line with available resources (particularly systemic therapy) (T = 83). Others included cancer registries (T = 62); prevention (T = 52); end-of-life care (T = 53); and value-based and affordable care (T = 51). The top COVID-19/cancer ARP was strategies to incorporate what has been learned during the pandemic that can be maintained posteriorly (T = 36). Others included treatment schedule interruption (T = 24); cost-effective reduction of COVID-19 morbidity/mortality (T = 19); and pandemic preparedness (T = 18).<br><br>CONCLUSION: Areas of strategic priority favored by cancer researchers in RCRs are related to adaptive treatment guidelines; sustainable implementation of cancer registries; prevention strategies; value-based and affordable cancer care; investments in research capacity building; epidemiologic work on local risk factors for cancer; and combatting inequities of prevention and care access.}, }

In addition, they determine post-infectious fatigue and organ dysfunction. Inflammation and oxidative stress are the principal pathogenic mechanisms responsible for clinical complications during respiratory seasonal viral infections. Nowadays, a growing body of evidence indicates that adjunctive nutritional support can contribute to relieve the symptoms during the acute and subacute phases of respiratory viral infections. We assess the data in the literature regarding the combination of L-Arginine and Liposomal Vitamin C as adjuvant treatment for respiratory seasonal viral infections. The database of the National Library of Medicine (PubMed) was searched using the keywords "L-Arginine, Vitamin C, dietary supplements, seasonal respiratory viral infections".

An academic search was conducted in August 2024, across Ovid MEDLINE, Embase and Scopus using controlled vocabulary and key words for sources published from 2020 onward. Grey literature was searched using Google and targeted government and organizational websites. Data were synthesized descriptively and analyzed deductively based on three pre-identified themes - public health, technological, and ethical-legal considerations - derived from the UK Royal Society's framework on COVID-19 vaccine certificate design. The search captured 128 sources (72 academic and 56 gray literature), covering all OECD countries except Chile, Colombia, Costa Rica, Mexico and Norway. Identified subthemes included: (1) purpose and trade-offs; (2) public health, socio-economic and health system impacts, (3) technological infrastructure and data security; (4) equity and accessibility; (5) privacy and surveillance; and (6) public acceptance and trust. Vaccine certificates aimed to support public health goals but posed challenges in digital implementation, particularly in creating secure and interoperable systems and raised concerns around equity, discrimination and privacy. Vaccine certificates show promise for future public health use. However, their success will depend on addressing ethical concerns, ensuring interoperability and strengthening digital infrastructure, regulations and public trust.}, }

This mucosa is characterized by a moist surface formed by the mucus overlying the epithelial cells. In the respiratory tract in particular, mucosa cells are constantly exposed to large amounts of environmental pathogens and stressors, including bacteria and viruses inhaled as aerosols. Therefore, mucins, a group of glycoproteins that constitute a major component of the mucus, play an important role in the innate immune defense provided by the protective mucus shield. This barrier function of the mucus can be disrupted by a number of agents, such as fine dust (particulate matter). Recent results have shown that inorganic polyphosphate (polyP), which can be administered, for example, in the form of a nasopharyngeal spray, offers a promising way to strengthen or repair impaired mucus function. This chapter describes the structure and formation of the mucus and its mucin building blocks, as well as the mode of action of polyP and drug-loaded polyP nanoparticles in restoring the mucus barrier, particularly with regard to their protective function against coronavirus infection.}, }

This perspective highlights key shifts in laboratory function, specifically toward decentralized testing, self-sampling, less invasive specimen types, point-of-care devices, and novel surveillance strategies.<br><br>AREAS COVERED: The surge in testing demand favored decentralized solutions, including rapid lateral flow tests, due to their flexibility, speed, and affordability. However, several challenges arose from the variable diagnostic accuracy of rapid self-tests and alternative specimen types when compared to reference laboratory-based molecular assays using nasopharyngeal swabs. For instance, the use of self-collected saliva, which is often preferred by patients, was hindered by a lack of internationally standardized processing protocols. A post-pandemic rebound in the circulation of respiratory pathogens other than SARS-CoV-2 was likely driven by both immunity debt and increased testing, including of less severe cases, commonly performed through more costly multiplex respiratory panels.<br><br>EXPERT OPINION: Moving forward, while over-the-counter self-tests for common respiratory viruses are now common, stricter regulatory oversight and improved data connectivity are essential. Local decision-makers must weigh the trade-offs between broad testing access and clinical performance, and implement robust diagnostic stewardship programs for acute respiratory infections.}, }

The fact that most widely used COVID-19 vaccines rely on the production of a biologically active SARS-CoV-2 Spike protein expressed by synthetic mRNA poses the relevant question of whether and how this vaccination influences the fate of the HIV-1 reservoir. This report presents a detailed analysis of the literature data on the effects of SARS-CoV-2 Spike and COVID-19 vaccines on HIV-1 latently infected cells. Despite being limited in number, the experimental evidences consistently indicate that vaccine mRNA and/or SARS-CoV-2 Spike can effectively reactivate latent HIV-1. This conclusion has been drawn after "in vitro", "ex vivo", and "in vivo" assays, and with virus-associated Spike, soluble Spike, or its intracellular expression, as well as with COVID-19 mRNA vaccines. On the other hand, real-world observations on vaccinated PLWH under antiretroviral therapy (ART) provided evidence of HIV-1 reactivation almost exclusively in PLWH with unsuppressed viremia, as measured in terms of size of the HIV-1 reservoir. Although several issues still need to be clarified through urgent additional investigations, these data suggest the possibility that the Spike protein and/or the vaccine mRNA molecules affect the HIV-1 latency in PLWH.}, }

Due to pressure overload and cardiac fibrosis, CVD often begin with hypertension and gradually progress to heart failure. Cardiac fibrosis reduces the number of functional cardiomyocytes and the force of contraction while increasing oxygen demand. It has been noted that myofibroblasts, which produce excessive amounts of extracellular matrix in the failing heart, express specific proteins such as periostin, tenascin C, thrombospondin, and osteopontin. Their activation involves immune cells that have a well-documented effect on the pathogenesis of hypertension. Moreover, dysregulation of the autonomic nervous system and sympathetic hyperactivity heightens peripheral inflammation and fosters fibrosis. In this review, we outline and summarize the most significant and recent findings concerning the molecular pathways of immune activation, neuromodulation, epigenetic modifications, and the impact of gut microbiota on myofibroblast activation and fibrosis in the heart, as well as potential therapeutic options (e.g. experimental anti-inflammatory treatments, epigenetic modulators, and vagus nerve stimulation). We will also highlight how current heart failure treatments, including renin-angiotensin-aldosterone system (RAA) inhibitors, β-adrenergic receptor (β-AR) antagonists, sodium-glucose co-transporter 2 (SGLT2) inhibitors, the Dietary Approaches to Stop Hypertension (DASH), and the Mediterranean diet, affect these processes at a molecular level.

At present, Western medicine still lacks the specific medicine or vaccines for coronavirus. However, amount of evidence shows that traditional Chinese medicine (TCM) has advantages in releasing the symptoms of mild-to-moderate COVID patients. Those treatments are not only improving the course of the primary disease but also curb progress to severe pneumonia or acute respiratory distress syndrome. Therefore, taking TCM intervention or combined treatments appropriately to prevent worsening illness is of vital significance. This study mainly focuses on the data analysis on the effects of TCM in restoring the immune balance of COVID patients. By collecting clinical data from mild to moderate patients, we expected to figure out if TCM only plays the role of curbing inflammation or having a two-way influence in balancing the immune microenvironment.<br><br>METHODS: Seven digital databases including PubMed, EMBASE, Cochrane Library, China National Knowledge Infrastructure, China Science and Technology Journal Database (VIP), Wanfang Database, and China Biology Medicine were searched from December 2019 to August 2022 nothingness of language restrictions. The studies retrieved from the database were selected and the data extracted to assess the methodological quality of the included randomized controlled trials (RCTs). Statistical analysis was completed. Pulmonary computed tomography, clinical cure rate, rate of conversion to severe cases, length of hospital stay, and scores of TCM syndrome were defined as the primary outcomes, the secondary outcomes were white blood cell count, lymphocyte (LYM) count, and C-reactive protein (CRP). This study was registered with PROSPERO (CRD42022341482).<br><br>RESULTS: Nine eligible RCTs including 1159 participants were included in this meta-analysis. Compared with Western medicine treatment alone, our meta-analyses found that traditional Chinese combined Western medicine treatment has a higher clinical cure rate, better absorption of lung inflammation, and significantly shorter hospital stay. In terms of inflammatory factors, TCM can significantly reduce the CRP content compared with Western medicine methods, but the leukocyte and LYM content was not significantly different between the two treatments. In some research, TCM even has a trend accelerating the inflammation process on some specific stages of the disease.<br><br>CONCLUSION: Chinese herbal medicine combined with conventional therapy is significantly effective and invulnerable in the treatment of mild-to-moderate COVID-19. In terms of control inflammation, TCM does not only block the disease onset by simply inhibiting inflammation but balancing the human environment through bidirectional regulation of inflammatory cells. However, considering of the lack of research into how TCM could activate the natural immune response, the discussion of the mechanism cannot be stretched, more high-quality RCTs are still needed in the future.}, }

Extending the duration of remdesivir from 5 days to 10 days did not improve efficacy but increased the risk of adverse events. Findings from this systematic review suggested that remdesivir may slightly improve recovery time and rate of clinical improvement.}, }

This review examines emerging evidence that extracellular vesicles act as key intermediaries linking complement activation to coagulation in acute and postacute COVID-19 infection.<br><br>RECENT FINDINGS: Recent studies demonstrate that extracellular vesicles released from platelets, endothelial cells, and neutrophils are markedly increased in COVID-19 and exhibit a combined procoagulant and complement-active phenotype. Sub-lytic complement attack, particularly membrane attack complex (MAC) deposition, triggers phosphatidylserine exposure and extracellular vesicle shedding, generating vesicles that support thrombin generation and propagate complement activity in the circulation. Extracellular vesicle-associated complement components, including C1q, C3 fragments, MASP2, and preassembled MACs, promote tissue factor decryption, platelet activation, and assembly of the prothrombinase complex, establishing a self-amplifying thromboinflammatory loop. Proteomic profiling further reveals compartment-specific extracellular vesicle signatures, with systemic extracellular vesicles enriched in complement and coagulation pathways. Importantly, complement-bearing and tissue factor-bearing extracellular vesicles persist beyond acute infection and are increasingly implicated in postacute sequelae of COVID-19.<br><br>SUMMARY: Extracellular vesicles serve as mobile platforms integrating complement activation with coagulation, providing a mechanistic framework for acute and chronic immunothrombosis in COVID-19. Targeting extracellular vesicle-mediated complement-coagulation crosstalk may offer novel diagnostic and therapeutic opportunities.}, }

Notably, although hydrocortisone-induced recovery can trigger osmotic demyelination and refeeding syndromes, no previous report has simultaneously described these complications and documented significant decreases in vasopressin levels, along with changes in urine osmolality and volume before and after hydrocortisone administration.<br><br>CASE PRESENTATION: A 48-year-old Japanese man presented with fever, severe nausea, and oliguria and was brought to our hospital by ambulance due to impaired consciousness. Physical examination and laboratory analysis showed severe euvolemic hypotonic hyponatremia and low-normal glucose value. Low adrenocorticotrophic hormone and cortisol levels, undetectable 24-hour urinary free cortisol, and minimal response to corticotropin-releasing hormone indicated secondary adrenal insufficiency. Magnetic resonance imaging revealed slight pituitary swelling, suggesting hypophysitis. Treatment started with a 200&#xa0;mg hydrocortisone infusion over 24&#xa0;hours, and 6 hours later, the patient experienced a marked decrease in vasopressin levels, accompanied by significant dilute urine excretion and an excessively rapid increase in blood sodium levels, which posed a risk of osmotic demyelination. Rehydration with 5% dextrose and desmopressin was used to prevent this risk. Carefully adjusting plasma osmolality successfully prevented osmotic demyelination syndrome. Hydrocortisone replacement significantly increased the patient's appetite, leading to refeeding hypophosphatemia and disorientation; however, these resolved with intravenous sodium phosphate replacement. The patient developed a fever on day 12 and was confirmed to have coronavirus disease 2019. The fever subsided by day 16 with molnupiravir treatment and hydrocortisone dose adjustment, and he was discharged on day 23 with a maintenance dose of hydrocortisone.<br><br>CONCLUSION: Careful management is required while administering hydrocortisone in patients with undiagnosed adrenal insufficiency, as it may cause osmotic demyelination syndrome or refeeding syndrome due to sudden changes in blood electrolytes.}, }

Given that, these symptoms may vary from person to person due to clinical, demographic, and genetic factors as well as comorbidities, our review aims to identify and analyze risk factors associated with persistent symptoms of COVID-19 (long COVID) in the specific context of sub-Saharan Africa.<br><br>METHODS: Article searches were conducted in the PubMed, Scopus, African Journals Online (AJOL), Science Direct and Google Scholar databases using the keywords "long COVID" or "long-term COVID-19" or "post-COVID condition" or "post-acute sequelae of COVID-19" and "sub-Saharan Africa" or "sub-Saharan Africans". The obtained data were entered into software for duplication checking. Two reviewers selected and extracted the data. Due to substantial heterogeneity in definitions and study designs, a narrative synthesis approach was adopted. Fifteen studies were included in this review, totaling 8,233 participants previously infected with SARS-CoV-2, with approximately 2,011 patients with long COVID from six countries. Six studies were cross-sectional, three were retrospective, three were cohort studies, two were case-control, and one was a case report.<br><br>RESULTS: The review found that the prevalence of long COVID in sub-Saharan Africa ranged from 2% in Ghana to 66.7% in South Africa. The persistent COVID-19 symptoms most commonly experienced by people living in sub-Saharan Africa were fatigue (reported in 12 studies, 25-66% of patients), cough (7 studies, 9-86%), chest pain (9 studies, 9%-29%), dyspnea (10 studies, 15-45%), palpitations (4 studies, 10-30%), headache (9 studies, 12-38%), and cognitive impairment (6 studies, 8-20%). The main risk factors for the occurrence of persistent COVID-19 symptoms were older age (&#x2c3; 60 years), female sex, low education level, hypertension, type 2 diabetes, cardiovascular disease, length of hospitalization during the acute episode, number of initial COVID-19 symptoms, and initial disease severity.<br><br>CONCLUSION: Long COVID is a reality in sub-Saharan Africa. Fatigue and hypertension have proven to be the most common symptom and risk factor, respectively. The heterogeneity of long COVID definitions across studies limits direct prevalence comparisons. Given the socio-economic challenges, pre-existing comorbidities and differences in health systems in the sub-Saharan region, it is therefore necessary to develop new strategies for care, rehabilitation and treatment (specific to the realities of the sub-Saharan region) targeted at each persistent symptom of COVID-19 in order to resolve this emerging problem and allow patients to have a good quality of life.<br><br>CLINICAL TRIAL NUMBER: Not applicable.}, }

Respiratory infections are major and potentially modifiable triggers of ECOPD, with viral pathogens such as the influenza virus, respiratory syncytial virus (RSV), and SARS-CoV-2, as well as bacterial infections caused by Streptococcus pneumoniae, playing a central role. This narrative review examines the current evidence supporting vaccination as a preventive strategy for ECOPD and discusses its translation into clinical practice. The biological rationale for vaccination in COPD is reviewed, including disease-related immune dysregulation, impaired mucociliary clearance, and increased susceptibility to respiratory pathogens. Evidence from randomized clinical trials, observational studies, meta-analyses, and real-world data is summarized for pneumococcal, influenza, SARS-CoV-2, and RSV vaccines. Pneumococcal vaccination has been shown to reduce the burden of community-acquired pneumonia and invasive pneumococcal disease, with conjugate and higher-valent vaccines providing enhanced immunogenicity in older and high-risk adults. Influenza vaccination consistently reduces severe exacerbations, hospitalizations, and mortality, with additional cardioprotective effects of relevance in COPD. SARS-CoV-2 vaccination markedly lowers the risk of severe COVID-19 and related respiratory deterioration in COPD, while recently licensed RSV vaccines offer a novel opportunity to prevent RSV-associated lower respiratory tract disease and potentially reduce exacerbation risk. Patient populations most likely to benefit from vaccination include frequent exacerbators, older adults, individuals with severe airflow limitation, multimorbidity, immune dysfunction, infection-prone phenotypes, and socially vulnerable groups. Future perspectives include precision vaccination strategies, novel vaccine platforms, coadministration approaches, and interventions to improve vaccine uptake. Vaccination emerges as a cornerstone of ECOPD prevention, with substantial potential to reduce exacerbation burden and improve long-term outcomes in COPD.}, }

Neutrophils are produced in bone marrow, have a short half-life in the blood, and are rapidly attracted to the tissues in response to infection or tissue damage.<br><br>SUMMARY: Glucocorticoids (GCs), stress hormones, and potent anti-inflammatory agents exert complex effects on neutrophils. While they generally suppress immune responses, GCs can paradoxically enhance neutrophil survival and function under certain conditions. This duality is evident in their ability to delay neutrophil apoptosis and to induce a shift of neutrophils from the marginated to the circulating pool, increasing the neutrophil presence in the bloodstream. Th17 cells, a subset of T-helper cells, recruit neutrophils to sites of infection and inflammation. In addition, neutrophils promote Th17 cell differentiation. GCs can enhance Th17 differentiation and IL-17 production, exacerbating neutrophil accumulation. Nevertheless, in glucocorticoid-resistant diseases, including multiple sclerosis (MS), traumatic brain injury (TBI), and encephalomyelitis, Th17 cells and neutrophils contribute to persistent inflammation. This resistance complicates the treatment of autoimmune diseases and chronic inflammatory disorders, also in the central nervous system, where standard glucocorticoid therapy fails to mitigate symptoms effectively.<br><br>KEY MESSAGES: In this context, we propose a mechanism for the development of resistance to GC driving by uncontrolled TH17 response and neutrophils induced by chronic stress. Understanding the interactions between neutrophils, Th17 cells, and GCs is essential for developing targeted therapies for diseases resistant to GC, such as MS, TBI, and encephalomyelitis.}, }

However, despite its efficacy, there are institutional barriers like capital constraints, resistance to change, data inconsistencies, and a lack of legislative frameworks that impede widespread LSS adoption.<br><br>CONCLUSION: LSS offers an adaptable and scalable methodology to re-engineer conventional hospital operations and pandemic preparedness. The emphasis on 'kaizen' (continuous improvement), data-informed decision making, and focus on precision aligns with the needs of healthcare systems as revealed by recent crises.

Initial hypotheses focused primarily on the spike protein antigen, with growing preclinical evidence implicating the lipid nanoparticle (LNP) delivery system as an additional and potentially important contributor to myocardial inflammation. Here, we propose a multi-hit model that integrates LNP-driven mechanisms as a central pathogenic axis, initiated by the systemic distribution and accumulation of LNPs in the heart. While the mRNA payload is cleared within days, the synthetic ionizable lipids -ALC-0315 (BNT162b2) and SM-102 (mRNA-1273) persist significantly longer than the mRNA payload itself. These two lipids differ in biodegradability and pharmacokinetic distinctions, together with differences in lipid dose and formulation, they may contribute to the divergent myocarditis rates observed between the two vaccine products. In this suggesting review, the first hit" involves the disruption of myocardial energy metabolism by these lipids, which can integrate into cellular membranes and impair mitochondrial fatty acid oxidation. This is compounded by a second hit of direct innate immune activation, preclinical studies demonstrate that LNPs engage pattern-recognition receptors (PRRs) like toll-like receptors (TLRs) and the NLRP3 inflammasome, leading to the release of pro-inflammatory cytokines such as IL-1β and IL-18. Inflammation is then amplified via Damage-associated molecular patterns (DAMPs) released from stressed cardiomyocytes. The clinical outcome-ranging from self-limited mild myocarditis to fulminant disease with diverse histopathological patterns-is likely shaped by host susceptibility factors, including sex hormones, genetic predisposition, and prior immune priming, that modulate the intensity of this pathogenic cascade.}, }

The heterogeneous, multisystemic nature and nonspecific symptomatology of long COVID-19 makes its treatment challenging. This scoping review evaluates existing evidence on sympathetic and parasympathetic ganglion blocks as potential interventions for patients suffering from long COVID-19.<br><br>OBJECTIVE: Our primary objective was to assess the effectiveness of sympathetic and parasympathetic ganglion blocks in treating patients with long COVID-19 by identifying the most commonly reported symptoms, symptom response to different block regimens, and any adverse effects associated with these interventions.<br><br>STUDY DESIGN: A scoping review.<br><br>SETTING: Outpatient clinics where patients received sympathetic blocks or parasympathetic blocks.<br><br>METHODS: A comprehensive search was conducted across PubMed, Embase, Cochrane CENTRAL, Web of Science, Google Scholar, and ClinicalTrials.gov using MeSH and free-text terms related to "long COVID-19," "post-COVID-19 syndrome," and "sympathetic ganglion blocks" and "parasympathetic blocks." Only English-language articles were included.

The most frequently studied symptoms were olfactory dysfunction, fatigue, headache, and cognitive disturbances. The most commonly utilized intervention was the stellate ganglion block. The available evidence suggests that the stellate ganglion block could be an effective treatment for dysautonomia symptoms and cognitive dysfunction related to long COVID-19. Sphenopalatine ganglion block may be an effective option to treat headaches in long COVID-19 patients who are refractory to other treatments.<br><br>LIMITATIONS: The significant existing variations in treatment regimens precluded our ability to do a quantitative analysis. Reporting bias from case reports and small observational studies should also be considered.<br><br>CONCLUSIONS: Stellate ganglion blocks may offer therapeutic benefit for the dysautonomia and cognitive dysfunction associated with long COVID-19. Sphenopalatine ganglion blocks have shown promise in managing refractory headache symptoms in this population.

However, in 2016, the discovery of trans-nuclease activity in CRISPR-Cas systems revolutionized the molecular diagnostics for nucleic acids. A typical CRISPR diagnostic workflow comprises three phases: (1) target recognition through CRISPR RNA (crRNA)-guided hybridization; (2) signal transduction via trans-cleavage of engineered reporters (e.g., fluorophore-quencher oligonucleotides), and (3) signal readout using fluorescence, electrochemical, or colorimetric platforms. Emerging shortly prior to the COVID-19 pandemic, CRISPR diagnostics quickly gained prominence as a field-deployable alternative to qPCR due to its rapidity (< 1 h), minimal equipment requirements, and field adaptability. This technological paradigm underwent rigorous validation and refinement alongside the rapid evolution of SARS-CoV-2 detection, which facilitated its adaptation for cancer diagnosis. Recent advancements in sensitivity (attomolar-level detection) and specificity (single-nucleotide discrimination) have enabled transformative applications in cancer diagnostics, including: (1) identification of nucleic acid biomarkers, such as high-frequency somatic mutations, circulating nucleic acids and miRNAs; and (2) detection of non-nucleic acid biomarkers, including epigenetic aberrations, proteins, small molecules and metabolite biomarkers. This review chronicles the decadal evolution of CRISPR diagnostics, with particular emphasis on recent advancements of its application in cancer diagnosis. We critically evaluate persistent technical limitations, including PAM sequence restriction, suboptimal sensitivity and specificity, quantitative constraints, and unmet point-of-care testing (POCT) in complex biological matrices. Additionally, we discuss prospective solutions to address these challenges.}, }

Therapeutic strategies that aim to restore a healthy endothelial monolayer include the inhibition of endothelial genes that cause EC injury and dysfunction and the induction or activation of endothelial genes that drive EC repair and regeneration. In this review, we describe established recombinase-mediated genetic modification technologies and emerging EC-specific genome editing technologies including viral and non-viral delivery of the CRISPR/Cas9 genome editing system, and we summarize the strengths and limitations of each technology.

Methods: A narrative review design was applied. A purposive literature search focused on national strategies, epidemiological trends, policy papers, and peer-reviewed articles published from 2000 to January 2026 was followed. Databases searched included PubMed, Scopus, PsychInfo, Embase and Google Scholar, supplemented by grey literature from the World Health Organization (WHO), European Commission, and national health authorities. The review focused on selected European countries, i.e., the United Kingdom, Sweden, Finland, Greece, and the Republic of Cyprus, chosen to illustrate variation in suicide prevention policies, health system structures, and implementation frameworks. Evidence was critically appraised and synthesized thematically to identify commonalities and contrasts in policy, implementation and emerging challenges. Results: The review identified substantial variation in national suicide prevention strategies, monitoring systems, and policy implementation across the selected countries. Persistent gender- and age-related disparities in suicide patterns were observed, alongside the influence of socio-economic determinants, and the broader mental health effects associated with the COVID-19 pandemic. The findings also underscored the need for robust, gender-sensitive, and data-driven national strategies that are contextually grounded and equitably resourced.

Human nasal epithelial organoids have emerged as accessible and patient-specific in vitro platforms with increasing translational relevance. This systematic review aimed to critically evaluate the current evidence on nasal epithelial organoid models, focusing on donor characteristics, culture methodologies, differentiation strategies, and translational applications. Methods: A systematic search of PubMed/MEDLINE, Embase, Scopus, Ovid MEDLINE, and Cochrane Library was conducted for studies published between 1990 and April 2026. The review followed PRISMA guidelines and was structured according to the PICOTS framework. Eligible studies included in vitro experimental investigations using human-derived nasal epithelial organoids in infectious, inflammatory, or precision medicine contexts. Risk of bias was assessed using the QUIN tool. Results: Seventeen studies met the inclusion criteria. Applications clustered into three principal domains: infectious disease modeling, inflammatory and epithelial remodeling research, and cystic fibrosis precision medicine. Most studies employed expandable three-dimensional Matrigel-embedded organoids or organoid-derived air-liquid interface systems. Infection-focused studies demonstrated variant-specific viral replication dynamics and epithelial immune responses, while inflammatory models reproduced disease-associated differentiation and remodeling phenotypes. Cystic fibrosis oriented studies showed that organoid swelling and electrophysiological assays correlate with CFTR functional rescue and, in selected cases, clinical response. Methodological heterogeneity across protocols and outcome reporting precluded quantitative synthesis. Conclusions: Human nasal epithelial organoids represent versatile translational platforms bridging accessible patient-derived tissue and advanced airway disease modeling. Although variability in culture protocols and functional benchmarks limits standardization, these models hold significant promise for mechanistic investigation, therapeutic stratification, and precision medicine applications.}, }

Affecting an estimated 400 million individuals globally, it imposes an annual economic burden exceeding $1 trillion, yet no pharmacological therapy has demonstrated consistent efficacy in adequately powered randomized controlled trials. Transcutaneous auricular vagus nerve stimulation (taVNS) has emerged as a candidate intervention targeting the autonomic dysfunction and neuroinflammation responsible for PCC pathophysiology. Methods: We conducted a PRISMA 2020-compliant systematic review (PROSPERO: CRD420261287286) searching PubMed, Scopus, Cochrane, and Web of Science databases from inception to January 2026 for studies evaluating any form of VNS in adults with Long COVID. Risk of bias was assessed using the Cochrane Risk of Bias 2 (RoB 2) tool, the JADAD scale, and the PEDro scale. Certainty of evidence was evaluated using the GRADE framework. Narrative synthesis followed SWiM guidelines. Results: Five studies (n = 154 participants) (three randomized controlled trials (RCTs) and two single-arm studies) met inclusion criteria. Three of five studies (60%) were rated high overall risk of bias; only two RCTs achieved "some concerns." The only adequately double-blinded RCT found no significant between-group differences across all outcomes. Paradoxically, in the best-powered RCT (Percin et al.), sham stimulation produced significantly greater fatigue improvement than active taVNS, despite active taVNS producing significant HRV increases consistent with cardiac autonomic modulation. All efficacy outcomes were rated "very low" certainty (GRADE); safety was rated "low" certainty. Conclusions: Currently available evidence supporting the use of taVNS for Long COVID remains limited, and the absence of reliable target engagement markers in the included studies constrains confidence in this approach. Nonetheless, the physiological rationale remains sound, and the favorable safety profile across all included studies supports the feasibility of future investigation. However, given that positive findings were confined to inadequately controlled studies, enthusiasm for further research should be directed first toward mechanistic clarification and rigorous dose-finding work. Large-scale, double-blind, sham-controlled trials incorporating validated markers of vagal engagement are required before taVNS can be firmly recommended for COVID-19 sequelae management.}, }

Two reviewers independently screened records in Covidence, with discrepancies resolved by a third reviewer. The percentage of studies evaluating >2 FS levels was determined. Dietary markers were classified into three domains: food and beverage (9 components), nutrient (16 components) and bioactive (2 components) markers. The percentages of studies with significant differences were estimated for each dietary domain. Results: Of 1069 records, 78 met full-text eligibility. Among these, 15% evaluated dietary markers across >2 FS levels. Among adults, differences by FS status were observed in 67% of assessed food and beverage components (6 out of 9), 50% of nutrient components (8 out of 16), and all evaluated bioactives (100%; 2 out of 2). Children exhibited differences in all assessed food and beverage components (100%; 9 out of 9) and 29% (2 out of 7) of nutrients by FS level. Adolescents had fewer dietary marker differences than children and adults. Findings among infants, pregnant women and older adults were limited, with no studies for lactating women. Conclusions: Low FS level is associated with poorer dietary markers across the lifespan compared with FS.

Whey and dairy products represent complex biological matrices that, beyond their high nutritional value, serve as reservoirs of bioactive proteins and peptides with documented health-promoting properties. It has been reported that certain whey proteins (WPs) and whey-derived peptides may contribute to improvements in both innate and adaptive immunity, exert direct antiviral and antibacterial effects while also modulating host defenses through immunoregulatory, antioxidant, and anti-inflammatory activities. These mechanisms contribute not only to enhanced resistance against viral pathogens but also to maintaining intestinal homeostasis and microbiota balance, both of which are critical during infection. In recent years, particularly in the context of the COVID-19 pandemic, natural bioactive compounds derived from whey, and, more broadly, milk, have attracted increasing attention as potential adjuncts or alternatives to conventional antivirals, with reported activity not only against SARS-CoV-2, influenza but also other viral and microbial infections. Despite encouraging in vitro and in vivo evidence, clinical validation remains limited, and the antiviral and immunomodulatory effects of WPs still require deeper mechanistic clarification. Future research should focus on identifying molecular targets, as well as characterizing the pharmacokinetics and safety profiles of WPs and WP peptides across diverse clinical settings. At the same time, attention should be given to optimizing their application as nutraceuticals or functional dairy ingredients.}, }

The question to be explored was whether dentists could use teledentistry to assess the caries risk index by calculating the DMFT (decayed, missing, and filled permanent teeth) score, thereby potentially reducing consultation time. Methods: A systematic English-language literature review was conducted, including the period from 2014 to 2024, that included the MeSH terms (("telemedicine"[Mesh]) AND "dental caries"[Mesh]) AND "DMF index"[Mesh]). Inclusion and exclusion criteria were defined according to the PICO methodology. A total of 11 manuscripts met the inclusion criteria. The methodological quality of these studies was assessed using the Newcastle-Ottawa Scale (NOS) with specific tools for cross-over studies. Results: From the 11 studies reviewed, it was suggested that teledentistry, through the use of intraoral photographs or video recordings, may represent a reliable, noninvasive, and efficient alternative for the detection of the caries experience index, compared to clinical examinations performed according to the traditional method. In most cases, the results were comparable between the two approaches. Conclusion: Incorporating teledentistry in combination with regular dental appointments could streamline clinical processes, enable effective treatment planning, and facilitate remote monitoring of the oral health status of patients, making it a timely and contemporary solution for a connected and health-conscious society-which is particularly valuable during public health crises such as the COVID-19 pandemic.}, }

Several countries, including India, have integrated traditional therapies with modern treatment protocols to enhance patient outcomes and reduce disease burden.<br><br>OBJECTIVES: This review aims to critically synthesize the existing evidence on the efficacy and safety of Ayush interventions in the management of COVID-19 in India. It seeks to qualitatively analyze published literature and clinical trial data, and to develop an evidence map categorizing interventions by type and associated clinical outcomes.<br><br>METHODS: A comprehensive literature search was conducted across seven electronic databases, including the National Repository on R&amp;D Initiatives of the Ministry of Ayush, WHO COVID-19 dashboard for clinical trials, AYUSH Research Portal, PubMed, Cochrane Library, WHO ICTRP, and CTRI. Studies published between 2019 and June 2024 were considered. A total of 3626 records were identified (2572 from indexed databases and 1054 from trial registries). After removing 640 duplicates, 2986 studies were screened for title and abstract. Following exclusion of 802 records, full-text assessment was performed on the remaining studies. After screening, 304 studies were included in the final review (178 Ayurveda, 22 Siddha, 31 Homeopathy, 22 Unani, and 51 Yoga). Risk of bias was assessed using the ROB 2 and ROBINS-I tools.

Antimicrobial peptides (AMPs) have emerged as promising candidates in the fight against these resistant pathogens. Naturally produced by a wide variety of organisms, AMPs are a crucial part of the innate immune system, offering a broad-spectrum antimicrobial effect against bacteria, fungi, viruses, and parasites. Unlike traditional antibiotics, AMPs primarily target microbial membranes, which reduces the likelihood of resistance development. Beyond their pathogen-destroying properties, AMPs enhance immune responses, aid in wound healing, and exhibit anticancer properties. Their ability to act swiftly and in synergy with the host immune system offers a distinct advantage over conventional antibiotics. Furthermore, AMPs hold the potential to be developed into novel treatments for infections that have become resistant to all available therapies. However, bacterial resistance mechanisms to AMPs-such as membrane modifications, protease production, and biofilm formation-underscore the complex interactions between hosts and pathogens. Despite these challenges, AMPs present an exciting avenue across multiple sectors, including medicine, agriculture, and food safety. Recent research also highlights their potential in treating viral infections, including COVID-19, showcasing their versatile applications. This chapter discusses the role of AMPs in addressing antibiotic resistance, their mechanisms of action, and their diverse therapeutic applications beyond bacterial infections.}, }

Management of intellectual property (IP) related to new medicines has a significant impact on access to safe, affordable and effective medicines. The Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS) provides the international legal framework for IP protection and mandates 20-year patents in all technological fields, including pharmaceuticals. TRIPS contains flexibilities, such as compulsory licensing (CL) and transition provisions for LDCs, which governments can use to facilitate access to health technologies. The use of these flexibilities is underreported in the literature, and a thorough analysis has not been undertaken since the COVID-19 pandemic.<br><br>METHODS: A scoping review of three medical and legal databases and temporal analysis of all known instances of use or potential use of CLs and the LDC pharmaceutical transition measure between 2001-2024.<br><br>RESULTS: 61% of the 149 CL instances were executed. The relative rates of CL use between countries have shifted: HICs represent over half of CL instances in the last decade. CLs are increasingly considered for chronic, non-communicable and rare diseases. The threat of CL use continues to provide impetus for price negotiations, voluntary licences or other measures to improve access. Almost all eligible countries have invoked the right to use the LDC transition measure.<br><br>CONCLUSIONS: TRIPS flexibilities have been used to facilitate access to medicines (including vaccines) over the quarter-century since the adoption of the World Trade Organization's Doha Declaration on TRIPS and Public Health. The flexibilities play a vital role in ensuring that new medicines are affordable and are likely to continue to be in a future where geopolitical forces have drastically altered the financing structures of medicines provision in DCs and LDCs.}, }

However, its clinical translation is limited by challenges such as data sparsity, batch effects (differences caused by technical variation rather than biology), and the absence of standardized benchmarks for core pipelines like Seurat and Scanpy. This review outlines emerging computational strategies that address these limitations: (A) robust preprocessing, including SCTransform for zero-inflation(an excess of zero counts in gene-expression data) correction and Harmony for batch integration-achieving 30% faster alignment than BBKNN in cohorts exceeding 100,000 cells; (B) transformer-based annotation tools such as scGPT and CellTypist, which reach >95% accuracy in immune profiling using models pretrained on 33 million cells; and (C) multimodal integration with spatial transcriptomics (e.g., 10x Visium, cell2location v2), which delineate microenvironmental niches and rare CX3CR1+ T-cell subsets in disease contexts like glioblastoma and severe COVID-19. We further assess how scANVI bridges scRNA-seq and ATAC-seq to uncover epigenetic mechanisms underlying therapy resistance, and how spatial methods elucidate tumor-immune crosstalk at subcellular resolution. Despite these advances, ethical risks remain, particularly around re-identification of rare patient-derived clones such as pre-metastatic cells. To promote clinical adoption, we propose a roadmap that prioritizes benchmarked workflows (e.g., scverse ecosystem), privacy-aware data sharing via federated learning, and causal AI approaches to disentangle biological signal from technical artifact. By synthesizing computational innovations with translational case studies, this review equips researchers to navigate both the analytical and ethical complexities of scRNA-seq in pursuit of actionable diagnostics.}, }

However, how clinical skills were taught online in pharmacy education, including the types of skills, approaches and technologies used, and the outcomes remain poorly understood. Objective To provide an overview of the types of clinical skills taught online in pharmacy education; and to identify the purposes, teaching strategies, technologies used, educational settings, enabling and limiting factors, and reported outcomes to inform future curriculum development in pharmacy education. Methods The scoping review was conducted in accordance with the Joanna Briggs Institute (JBI) Scoping Review methodology. A systematic literature search was conducted in MEDLINE, CINAHL, and ERIC databases using predefined inclusion and exclusion criteria, and the records were independently screened by four reviewers. Any discrepancies during the screening process were resolved through discussion. The data were extracted and then analyzed using content analysis and thematic analysis. Results A total of 349 studies were retrieved and proceeded to title and abstract screening. After applying the inclusion and exclusion criteria, 152 full-text articles were assessed for eligibility, of which sixty-four articles were included in the final review. Online synchronous, asynchronous, and blended learning were implemented in pharmacy education to teach clinical skills, including communication skills and therapeutic decision-making skills. Clinical skills were most often taught online to improve the learning process. Learning outcomes measured by self-assessment or by educators were most commonly reported. Enablers, including institutional readiness and technology infrastructure, and barriers, including institutional unpreparedness and inadequate design, were also identified. Conclusion This scoping review provides guiding information to integrate online teaching and learning into pharmacy curricula, particularly for clinical skills development. By including multiple stakeholders' perspectives, this review offers useful insight for academics and faculty leaders to successfully teach clinical skills online to pharmacy students.}, }

Although vertical transmission of the virus from mother to fetus appears to be relatively infrequent, growing clinical and epidemiological evidence indicates that prenatal exposure to SARSCoV-2, as well as to the maternal immune response it elicits, may have significant implications for early neurological development. Therefore, understanding the potential cognitive consequences of congenital COVID-19 is essential for the long-term monitoring of child health in affected individuals and for the implementation of early intervention strategies. This post-pandemic perspective on the consequences for neural development has been supported by observations showing that neonates exposed to congenital COVID-19 infection have a tenfold higher incidence of developmental delay compared with those not exposed to the virus.

However, accumulating evidence reveals a complex, context-dependent role for VWF in inflammation and innate immunity that extends well beyond coagulation. VWF acts not only as a biomarker of endothelial activation but also as an active participant in immune responses. VWF directly interacts with major immune cell types-including macrophages, polymorphonuclear leukocytes (neutrophils), and dendritic cells-through both its endothelial-anchored and plasma forms. VWF facilitates leukocyte recruitment and transmigration across the vessel wall, while its interactions also promote macrophage and neutrophil activation as well as NET formation. VWF's immunomodulatory functions are further highlighted by its binding to extracellular DNA, smooth muscle cells, complement components (C1q and C3), and bacterial pathogens under flow conditions. Furthermore, VWF indirectly influences inflammation via its crucial role in Weibel-Palade body formation, a process that co-packages vital inflammatory mediators like P-selectin and angiopoietin-2. Markedly elevated VWF levels are consistently observed across acute and chronic inflammatory conditions such as sepsis, COVID-19, and autoimmune disorders, confirming its relevance as both a diagnostic marker and a therapeutic target. A comprehensive understanding of VWF's diverse functions in vascular inflammation is crucial for developing targeted therapeutics-including nanobodies, ADAMTS13 variants, and VWF interaction inhibitors-capable of modulating pathological thrombo-inflammation while preserving physiological hemostasis.}, }

Healthcare providers play a pivotal role in outbreak prevention, early detection, isolation, and response. This systematic review and meta-analysis aimed to assess the pooled prevalence of knowledge and attitude toward Mpox among healthcare providers in Sub-Saharan Africa (SSA).<br><br>METHODS: This systematic review and meta-analysis was conducted in accordance with the PRISMA guidelines. A comprehensive literature search was performed in PubMed, ScienceDirect, Hinari, and Google Scholar to identify eligible studies published between 2 July 2015 and 2 July 2025. Data were extracted and managed using Microsoft Excel and analyzed using STATA version 17. Pooled prevalence estimates were calculated using a random-effects model. The methodological quality of included studies was assessed using the Joanna Briggs Institute (JBI) Critical Appraisal Checklist. Publication bias was examined using funnel plots and Egger's regression test, and statistical heterogeneity was assessed using the I[2] statistic. The review protocol was registered in PROSPERO (CRD420251123652).<br><br>RESULTS: This systematic review and meta-analysis included seven studies from Sub-Saharan Africa, comprising a total of 3379 healthcare providers. The pooled prevalence of adequate knowledge and a positive attitude toward Mpox was 40.52% (95% CI, 30.17-50.88) and 51.20% (95% CI, 44.48-57.91), respectively, with high heterogeneity (I[2]&#x2009;>&#x2009;90%). Factors associated with higher knowledge included age over 40&#xa0;years (AOR&#x2009;=&#x2009;5.90; 95% CI, 1.27-27.41), being married (AOR&#x2009;=&#x2009;1.58; 95% CI, 1.24-2.01), being a physician (AOR&#x2009;=&#x2009;6.82; 95% CI, 1.38-33.56), having 5-10&#xa0;years of work experience (AOR&#x2009;=&#x2009;7.02; 95% CI, 1.51-32.74), prior information about Mpox (AOR&#x2009;=&#x2009;1.82; 95% CI, 1.11-2.97), and a history of COVID-19 vaccination (AOR&#x2009;=&#x2009;1.98; 95% CI, 1.47-2.68).

Approximately 45.06% of the projects (n = 251) aimed to enroll 0-100 participants. Most of the studies involved mRNA vaccines (n = 507, 91.02%). Further, 22 trials investigated mRNA-based therapeutics for rare diseases. Among the newly registered projects in 2024 and 2025, the proportion of phase 0-1 trials significantly increased, accounting for 61.67% and 78.13%, respectively. The top three regions that conducted mRNA clinical studies were North America (n = 186; primarily the United States [n = 178]), Asia (n = 184; China [n = 72]), and Europe (n = 90), based on studies registered in both CTg and ChiCTR.

The most frequently cited barrier was excessive workload, both from existing responsibilities and additional tasks introduced by DHIs. The leading facilitator was the perceived positive clinical impact of DHIs-such as improved adherence, reduced hospital readmissions, and better outcomes. HCP motivation, adequate training, and system integration also facilitated adoption. Many factors-like effects on HCP-patient relationships and workflow-functioned as either barriers or facilitators, depending on the setting. Patient-related barriers included limited digital access and literacy; facilitators included perceived gains in patient-centered care.

While some digital health tools can be time-saving, many providers feel that they add burdensome technical tasks to their already busy schedules, which undermines their acceptance.Uptake is also influenced by patient-related factors, such as digital literacy and internet access, as well as technological factors like how easily a tool integrates into existing hospital computer systems.To improve the future of cardiovascular care, digital tools should be co-designed with clinicians to ensure they fit seamlessly into daily work routines and are supported by proper training and strong institutional leadership.}, }

These receptors detect pathogen- and damage-associated molecular patterns (PAMPs and DAMPs), triggering inflammatory cascades. Opioids, beyond their analgesic role, modulate innate and adaptive immune responses via opioid receptors and indirectly through TLR and P2X signaling. This narrative review integrates experimental, clinical, and bioinformatic evidence to explore the mechanistic crosstalk between opioid signaling, TLRs (notably TLR2, TLR4, TLR9), and P2XRs (notably P2X4 and P2X7) in COVID-19 immunopathology. Chronic opioid exposure may either enhance or suppress inflammation depending on dose, duration, and immune context. In COVID-19, the hyperactivation of TLR4, TLR7, and TLR9 drives cytokine storms, while the release of ATP from damaged cells activates P2X7, thereby amplifying the inflammatory response. ATP breakdown into adenosine further modulates immunity via A2A and A2B receptors. Targeting TLR4 and P2X7 offers a promising therapeutic strategy to mitigate hyperinflammation and improve outcomes in COVID-19 and related inflammatory diseases. In addition, we outline how the Contact System, the Kallikrein-Kinin System (KKS), the Renin-Angiotensin System (RAS), and the NLRP3 inflammasome provide the innate inflammatory backdrop through which opioids and P2 receptor signaling may shape immune dysregulation in COVID-19. Notably, direct clinical evidence for opioid-P2 receptor interactions in COVID-19 remains limited, highlighting the need for targeted translational studies.}, }

However, the broad clinical translation of RNA therapeutics remains critically dependent on the development of safe and effective delivery systems that are capable of overcoming physiological barriers and achieving precise spatiotemporal upregulation or downregulation of target proteins. Lipid nanoparticles (LNPs) have attracted significant attention due to their clinical success, yet they still struggle to overcome context-specific delivery barriers, such as poor stability in blood or gastrointestinal fluids, lack of disease-microenvironment responsiveness, and insufficient cell-type targeting, which hinder the full implementation of RNA therapeutics across a broad spectrum of diseases. To tackle the unmet needs in RNA-based therapeutics, developing new types of delivery platforms with different nanoparticle structures is therefore highly attractive and needed. Over the past decade, our group has focused on developing novel lipid-polymer hybrid nanoparticles (LPHNPs) for the delivery of RNA therapeutics across diverse biomedical applications. By incorporating biodegradable polymers with tailored properties, for example, poly(lactic-co-glycolic acid) (PLGA) for structural stability, hyaluronic acid (HA) for CD44-mediated targeted delivery, and l-cysteine-based poly(disulfide amide) (Cys-PDSA) for redox-responsive release in the tumor microenvironment, these LPHNPs exhibit highly tunable architectures that integrate efficient RNA encapsulation, site-specific delivery, and controlled RNA release, providing more tools and choices for RNA delivery. In this Account, we summarize recent advances from our group in the design and synthesis of LPHNPs for RNA therapeutics, as well as their translational applications across diverse disease contexts. We highlight rational material pairings and design principles that optimize key performance metrics, including colloidal stability, RNA loading, cellular uptake, endosomal escape, and targeting efficacy. We also provide case studies demonstrating the translational potential of RNA-LPHNPs across various administration routes and disease models, including oral, inhaled, intravenous, and intravesical delivery, using the LPHNP platforms developed in our laboratory. These platforms have achieved promising therapeutic efficacy in models of cancers, inflammatory diseases, and respiratory conditions by enabling local or systemic delivery of mRNA or siRNA to immune cells, epithelial cells, and tumor microenvironments. By outlining optimized design strategies and future challenges, this Account aims to serve as a roadmap for researchers seeking to develop next-generation RNA delivery platforms that are modular, functionally versatile, and translatable.}, }

Drug repurposing, defined as the use of existing medications for new therapeutic purposes, was extensively pursued for SARS-CoV-2 but has not yielded successful treatments. This narrative review critically examines the pharmacological and methodological factors that contributed to these unsuccessful outcomes, paying particular attention to tests of azithromycin and hydroxychloroquine. There are many reasons the promise of repurposed drugs was not realized. Many repurposed compounds displayed promising in vitro antiviral activity that did not translate into clinical efficacy. Major pharmacokinetic (PK) limitations, for example, poor oral bioavailability, low concentrations in pulmonary tissue, and extensive plasma protein binding, prevented these drugs from reaching therapeutic levels in humans. Preclinical research often relied on non-human cell lines and animal models that inadequately reflected human physiology, leading to misleading experimental outcomes. Clinical trials were often undermined by methodological limitations, including endpoints with uncertain clinical significance, suboptimal comparators, and insufficient attention paid to key PK and pharmacodynamic (PD) parameters such as half maximal effective concentration (EC50) values. This narrative review emphasizes the importance of integrating comprehensive PK/PD assessments, relevant experimental models, and rigorous trial design to strengthen drug development during future health crises. The relative success of antivirals including molnupiravir, nirmatrelvir, and remdesivir, which were either novel or previously unapproved compounds, suggests the value of designing and developing targeted antivirals. We must coordinate global research, develop pharmacologically sound strategies, and use evidence-based decision-making to effectively prepare for future pandemics and quickly produce effective treatments.}, }

Testament to its success is the eradication of infectious diseases, such as smallpox, that devastated human populations for almost 4000 years. Live-attenuated vaccines (LAV), which retain the capacity for infection and replication, were the first to be developed and remain highly efficacious, underpinning successful human vaccination campaigns (e.g. polio virus, measles virus, yellow fever virus). The cost of this success is the capacity of LAVs to cause disease in a small proportion of recipients, typically owing to overt or previously unappreciated immunodeficiency. From the careful investigation of such rare events, major clinical and scientific lessons about human antiviral immunity have been drawn. Here, we review features of pathogenic LAV dissemination, which continue to inform our understanding of critical steps in the immune control of LAVs. We discuss recent data on specific variants identified in geographically isolated populations and reflect on more common phenocopies of these monogenic defects, with potential implications for vaccine practice and policy. Collectively, these insights may inform approaches to the growing population of individuals rendered more vulnerable to LAVs by aging, multimorbidity or medical intervention. They also serve to highlight the clinical need for therapeutic strategies to combat pathogenic LAV dissemination.}, }

This systematic review aimed to examine and meta-analyse the existing literature on food insecurity in families of children and young people with ASC. A comprehensive search across nine databases identified 39 papers, of which 11 met the inclusion criteria. Studies were included if they involved autistic children or young people under the age of 25 (and/or their family members) and focused on food insecurity. Eligible studies were critically appraised, and data were synthesised using both narrative and meta-analytic approaches. Meta-analyses of nine studies estimated a pooled prevalence of food insecurity at 29% (SE: 5%; 95% CI: 17%-40%; z = 5.35, p < 0.001), which increased to 31% following adjustment for publication bias. The review also found that food insecurity worsened during the COVID-19 pandemic, contributing to increased caregiver stress and disruptions in eating behaviours. This review demonstrates the high prevalence of food insecurity among families of children with ASC and the complex interplay of social, economic and behavioural challenges they face. Addressing food insecurity in autistic households requires policy responses that extend beyond financial aid to consider the sensory, behavioural and nutritional needs specific to ASC. Future research should adopt standardised measures and prioritise the development and evaluation of inclusive, tailored food support systems that reflect the lived experiences of neurodiverse families.}, }

Especially post-COVID-19, its prevalence has surged, posing a significant threat to 21st-century health. CFS symptoms are intricate and diverse. Patients typically endure extreme fatigue lasting over six months, accompanied by physical and neuropsychiatric symptoms like sore throat, muscle/joint pain, anxiety, and distress.

While often viewed as "two sides of the same coin," the nexus between these two phenomena is contingent and strategic rather than deterministic. Not all populists are Eurosceptic, and Euroscepticism is not always populist in nature. This publication synthesizes current scholarly debates, highlighting how the European Union (EU) is frequently framed as the populist "other", i.e., a remote, technocratic elite standing in opposition to the "pure people". The nature of this opposition varies significantly across the ideological spectrum, e.g. right-wing populism targets the EU primarily through a "traditionalist-authoritarian-nationalist" (TAN) lens, viewing it as a threat to national sovereignty and cultural identity, while left-wing populism critiques the EU based on socio-economic cleavages, challenging neoliberal governance and austerity while often advocating for a more democratic "Social Europe". The analysis further explores how the polycrisis era-marked by financial instability, the COVID-19 pandemic, and geopolitical conflict-has led to a sophisticated two-level strategy among populist actors. This involves increased institutional pragmatism coupled with radicalized, opportunistic communication, particularly on social media. Finally, the publication outlines the EUPopLink mandate, which seeks to standardize conceptual frameworks and generate an unprecedented body of comparative data through forthcoming country reports. By linking the supply and demand sides of electoral competition, the project aims to provide policymakers and scholars with the tools necessary to mitigate the negative consequences of these disruptive political forces.}, }

In contrast to early pandemic predictions, Africa recorded the fewest SARS-CoV-2 related hospitalizations and deaths. Hypotheses proposed to explain this paradox include underreporting, age demographics, climate, national mitigation strategies, lifestyle factors, pre-existing cross-reactive protection, and host genetic determinants. This traditional, narrative review evaluates these hypotheses investigated in the published literature, and highlights knowledge gaps which limit our understanding and obscure validation of potential explanations. It also discusses how responses to vaccines, the primary intervention sought to control infectious disease outbreaks, may vary both within the African population and across other continents. Potential explanations in the literature include pre-existing immunity, poor nutrition, immune modulating co-infections, comorbidities, microbiome composition, genetic polymorphisms, and demographic factors. Previous studies have shown that pre-existing (infection-derived) immunity or cross-reactive immune responses can augment vaccine-elicited positive responses and can protect against reinfection in a way similar to immunization. Conversely, there are also studies showing that prior immunity interferes with the efficacy of new vaccines through mechanisms like original antigenic sin and immune imprinting. Thus, there is need for more immunology studies to understand the relative contribution of pre-existing cross-reactive immune responses to the epidemiology of new pathogens. These studies are particularly essential to understand the differences between pandemic preparedness and population vulnerability, as well as to inform vaccine development and vaccine effectiveness monitoring studies. SARS-CoV-2 serves as an important case study to understand heterogeneity between and within populations in immune responses to both the pathogen and to vaccination. This understanding is crucial in informing vaccine research and development aimed at supporting the 100-day mission for when the next pandemic threat emerges.}, }

This comprehensive review examines the evolving role of immunization and infection control measures in reducing perioperative complications, with particular emphasis on the Saudi Arabian healthcare context. The coronavirus disease 2019 pandemic has highlighted the importance of vaccination timing in relation to elective surgery, while established infection prevention practices continue to form the cornerstone of safe perioperative care. In Saudi Arabia, national initiatives have demonstrated significant improvements in healthcare-associated infection rates, with central line-associated bloodstream infections decreasing from 2.5 per 1000 catheter-days in 2021 to 1.28 per 1000 catheter-days by 2024. The implementation of evidence-based vaccination protocols and comprehensive infection prevention strategies has shown measurable benefits in reducing surgical site infections, respiratory complications, and overall perioperative morbidity. Anesthesiologists play a pivotal role in this public health framework, serving as key stakeholders in perioperative optimization through vaccination status assessment, infection control adherence, and risk stratification. The Saudi healthcare system's commitment to infection prevention excellence, aligned with Vision 2030 objectives, provides a unique model for integrating public health principles into anesthetic practice. Current evidence supports the strategic timing of vaccinations relative to elective procedures, with recommendations for postponing elective surgery 3-7 days after inactivated vaccines and 14-21 days following live vaccines.

A PubMed search was conducted through October 2025 to identify studies evaluating AI systems for the detection of COVID-19 pneumonia using CXR and CT. Studies reporting diagnostic performance metrics, including sensitivity, specificity, accuracy, or area under the curve (AUC), were included. Study quality and risk of bias were assessed using the Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2) tool. Eleven studies met the inclusion criteria. CXR-based AI systems demonstrated sensitivities from 80% to 98% and specificities from 82% to 96%, often comparable to radiologist performance. CT-based AI models achieved accuracies between 90% and 96%. AI models demonstrated strong internal diagnostic performance on CXR and CT but showed reduced accuracy with external validation, underscoring limitations related to generalizability and retrospective study designs. AI models demonstrate promising diagnostic performance for detecting COVID-19 pneumonia on chest imaging and may enhance radiologist efficiency. However, challenges related to generalizability, model adaptability, and clinician trust remain.

The accelerated development of effective vaccines inspired the Coalition for Epidemic Preparedness Innovations to promote the 100 Days Mission (100DM), an initiative to enable deployment of medical countermeasures within 100 days of identifying a pandemic threat. The success of the 100DM in uniting stakeholders highlights the power of framing challenges to inspire collective action. On the other hand, antimicrobial resistance (AMR) has had insufficient visibility and urgency to galvanize similar levels of political action. Framing AMR in a way that highlights the urgency, aligns incentives and builds multisectoral coalitions can help overcome some of these barriers. Ultimately, pandemic preparedness and AMR are both collective action problems, requiring sustained political will and systemic change. The AMR community must build systems that are agile and resilient and, by creating a unifying vision for AMR analogous to the 100DM, may promote global commitment to combating this slow-moving but devastating health crisis.

Maternal immunization boosts the concentration of maternal antibodies that can be transferred across the placenta to directly protect children too young to be immunized. In addition, indirect protection through prevention of maternal infection and breast-milk antibodies can be achieved through maternal immunization. In general, inactivated vaccines are considered safe for pregnant women and fetuses, whereas live attenuated vaccines are avoided due to the theoretical potential risk of infection to the fetus. However, the potential risks of vaccines need to be weighed against the risk of the disease itself and the benefits of vaccination in terms of protection of the mother and child against infectious disease. Tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap); influenza; coronavirus disease 2019 (COVID-19); and respiratory syncytial virus (RSV) vaccines are routinely recommended for all pregnant women in the United States. Maternal immunization has the potential to improve the health of mothers and young children; therefore, other diseases of relevance during this period are now targets of active research and vaccine development, including group B streptococcus (GBS). Similarly, several vaccines can be administered during pregnancy in special circumstances when maternal health, travel, or other special situations arise.

Any impairments of their functionalities can have severe consequences, since these lymphocytes each contribute as an interactive team in responding to pathogen infections or cancers. Such impairments include lymphocyte exhaustion, such as T cell, B cell, or natural killer cell exhaustion, or lymphocyte suppression impairing one or more of these cells. Lymphocyte exhaustion can have any intensity from mild to severe, having a severity scale worsened by various exposures and time periods of constant antigenic activation. Lymphocyte exhaustion can potentially have a conventional timing pathway or a hypothesized accelerated (pipelined) timing pathway. Lymphocyte suppressions initiated from pathogen infections are also possible, and this can also impair multiple types of lymphocytes. Finally, accelerated T cell exhaustion is possible, and this can explain several puzzling characteristics of virulent viral pandemics, especially in individuals having pathogen or cancer comorbidities. For instance, accelerated T cell exhaustion can explain a substantial percentage of the SARS-CoV-2 pandemic fatalities and also explain the relatively small, but significant, numbers of hyperinflammatory diseases or autoimmune diseases which were initiated in small percentages of individuals by SARS-CoV-2 infections.}, }

We review the impact of the COVID-19 pandemic on influenza transmission dynamics, public health policy, and the evolving burden of cardiovascular complications. New evidence indicates that both diseases exacerbate endothelial dysfunction, systemic inflammation, and prothrombotic states, thereby increasing cardiovascular risk.

Traditional diagnostic tools, including clinical prediction scores, D-dimer testing, and imaging, are limited by suboptimal specificity or sensitivity. In this context, proteomics-based approaches have emerged as powerful tools to elucidate the molecular mechanisms of VTE and to identify novel diagnostic and prognostic biomarkers. This review synthesizes recent advances in proteomic research relevant to VTE. We searched four databases (PubMed, ScienceDirect, Springer Nature, and Wiley) using the keywords "acute pulmonary embolism", "acute venous thromboembolism", and "proteomics". Thirty proteomic studies investigating VTE were examined. Across these studies, proteomic profiling consistently revealed alterations in pathways related to coagulation, inflammation, platelet activation, endothelial dysfunction, and fibrin clot structure. Multiple protein classes, including acute-phase reactants, complement components, coagulation factors, and platelet-derived proteins, have demonstrated potential value in improving diagnostic accuracy and refining prognostic stratification. Proteomic analyses have also revealed distinct molecular signatures between isolated PE and isolated DVT, supporting the concept of biologically heterogeneous VTE phenotypes. Furthermore, emerging evidence from COVID-19-associated thrombosis, cancer-associated VTE, and non-invasive sources such as exhaled breath condensate underscores the expanding clinical relevance of proteomic approaches. Although technical limitations and heterogeneity across studies remain challenges, the integration of proteomic data with clinical and genetic information holds promise for advancing precision medicine in VTE.}, }

We performed a random-effects meta-analysis and assessed the certainty of the evidence using the GRADE approach. Eighty-four studies (n = 4,778) were included; seven had a comparator group. The frequency of cardiovascular outcomes-including coronary abnormalities (Z-score ≥ 2), left ventricle ejection fraction < 55%, diastolic dysfunction, myocarditis, and pericardial effusion-decreased over time, with most resolving by 6 to 9 months. However, cardiac magnetic resonance imaging studies identified myocardial edema and/or fibrosis persisting up to 12 months, and two studies reported coronary abnormalities at 18- to 24-month follow-up. Evidence certainty was very low. Compared to children with COVID-19 or healthy controls, MIS-C showed more cardiovascular events and greater subclinical myocardial dysfunction, as assessed by strain analysis, during a 6-month follow-up. Compared with other etiologies of myocarditis, MIS-C myocarditis was associated with better cardiovascular outcomes but shorter exercise duration and lower aerobic capacity on stress testing. Conclusions: Cardiovascular outcomes following MIS-C improved over time, but certain subclinical cardiac abnormalities persisted up to 12 to 24 months. These findings may support long-term follow-up after MIS-C.Trial registration: Protocol registration number: PROSPERO, CRD42022336784.}, }

Since the beginning of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, Azvudine has been used to treat patients with COVID-19. Therefore, the objective of this meta-analysis study was to compare Azvudine and Nirmatrelvir-Ritonavir in hospitalised patients. The global online databases were used to identify relevant studies published between January 2019 and October 2024. The quality of all articles was determined using the Newcastle-Ottawa Scale (NOS) checklist. In this study, heterogeneity assay was assessed using the Cochran's Q-test and the I2 index, and STATA software version.14 (StataCorp) was used for statistical analysis. Egger's test, Begg's test, and funnel plot were performed to estimate of the publication bias, and the impact of each study on the overall estimate was assessed using sensitivity analysis. In this study, 19 studies were included in this meta-analysis. The results of the meta-analysis showed that the relative risk of death in the Azvudine treatment group compared with the Nirmatrelvir-Ritonavir treatment group was 0.64 (95% CI: 0. 44, 0. 93). These results suggest that treatment with Azvudine may provide significant clinical benefit in patients hospitalised with COVID-19.}, }

Drawing on examples from debt distress, vaccine apartheid, and intellectual property monopolies during COVID-19, this commentary demonstrates that global health governance operates less as solidarity than as economic containment. Reparative justice provides the necessary rupture.

(2010), and reported per PRISMA-ScR (2018) guidelines, a comprehensive search was conducted in PubMed, Scopus, and Web of Science (January 2020&#x2013;June 2025). Studies in English, Portuguese, or Spanish addressing reporting practices, barriers to reporting, digital platforms, or policies regarding WPV against HCWs were included. Two reviewers independently screened and extracted data using a structured matrix, resolving discrepancies by consensus. Results were summarized narratively with frequency analysis.<br><br>RESULTS: From the initial 232 records, 35 studies met inclusion criteria, from 19 geographic areas across 5 continents. Most studies originated from Asia and Europe. Verbal violence was the most frequently reported form (20&#x2013;91%), and over half reported underreporting rates exceeding 50%. The most frequently reported individual barrier was the belief that reporting is ineffective (60%), while the most cited systemic barrier was ineffective reporting systems (63%). National digital platforms reporting included the WVIRS system (California), the Synergic system (Sweden), the White Code system (Turkey), and the NOTIFICA, SAGRIS and HER+ systems (Portugal).

Perceived severity (r = 0.17) and susceptibility (r = 0.18) to COVID-19 were also significant positive predictors, each with small-to-medium effect sizes. Cues to action (r = 0.11) and self-efficacy (r = 0.10) were also positively associated with vaccine acceptance, although the effects were small. In contrast, perceived barriers to vaccination (r = -0.25) were negatively associated with vaccine acceptance, approaching a medium effect in size. Several of these associations were moderated by study characteristics, including how the variables were operationalized (intention, hesitancy, refusal, etc.), the vulnerability of the study sample, the respondent type (parents vaccinating children vs. adults vaccinating themselves), the vaccine development stage, and the variant phase. Overall, these findings contribute to a deeper understanding of the psychological mechanisms underlying vaccine acceptance and hesitancy, and offer practical implications for developing targeted communication strategies to promote COVID-19 and other vaccinations.}, }

It brings together molecular evidence, immunological perspectives, and epidemiological insights to summarize current hypotheses and working models of these complex disease interactions. We summarize and critically discuss evidence on antibody-dependent enhancement (ADE), cross-reactive immune responses, and cytokine amplification pathways, and propose mechanisms that could underlie exacerbated disease severity. Published clinical data indicate heterogeneity in co-infection outcomes globally, from mild presentations to severe complications, such as hemorrhagic stroke, acute kidney injury, and increased mortality, particularly among populations with prior dengue exposure. Diagnostic complexities arising from serological cross-reactivity underscore the need for simultaneous molecular testing to ensure accurate pathogen identification. Additionally, we review current evidence on reciprocal selective pressures between SARS-CoV-2 variants and dengue serotypes, highlighting potential evolutionary impacts arising from their co-circulation. The available evidence suggests that co-infection may exacerbate inflammatory pathways, lead to increased vascular and organ damage, and complicate patient management. However, definitive clinical evidence for ADE remains inconclusive, underscoring an ongoing need for targeted mechanistic studies.

To tackle this AMR pandemic, regulatory and policy frameworks have been prepared at local, national and international levels with multi-faceted proposals and advances encompassing surveillance, diagnostics, infection prevention, antibiotic prescribing and variation of existing and novel treatment approaches. This narrative review primarily focuses on research and development which have been documented over the last five years in relation to therapeutic approaches at various stages in clinical development and the potential role that vaccines can play in the fight against AMR. This review provides an overview on antibacterial drugs, including novel classes of antibiotics, which have been recently approved, as well as combination antibiotic therapy and the potential of repurposed drugs. The potential role of novel antimicrobial, antibiofilm and quorum sensing inhibitors, such as antimicrobial peptides, nanomaterials and compounds from the extreme and natural environments, as well as ethnopharmacology including the antimicrobial effects of plants, spices, honey and venoms are explored. Novel therapeutic approaches are critically discussed in terms of their realistic clinical potential, detailing recent and ongoing trials to highlight the current interest of these approaches, including immunotherapy, bacteriophage therapy, antimicrobial photodynamic therapy (aPDT), antimicrobial sonodynamic therapy (aSDT), nitric oxide therapy and microbiome manipulation including faecal microbiota transplantation (FMT). The potential of predatory bacteria as living antimicrobial agents is also discussed. Importantly, there have been many technological developments which have enhanced bioprospecting and research and development of novel antimicrobials which this review draws attention to, including artificial intelligence, machine learning and Organ-on-a-Chip devices.

Acute infection predominantly impacts the respiratory tract, but there is growing evidence for the multisystem involvement, such as cardiovascular, metabolic, and neurological, to be responsible for the prolonged presentation in PCS. Underlying cardiometabolic vulnerability may contribute to a high degree of susceptibility in patients with comorbidities like hypertension (HTN) and diabetes mellitus (DM). This narrative review summarizes current literature regarding PCS in patients with HTN and/or DM, focusing on proposed pathophysiological mechanisms, clinical manifestations, and reported long-term outcomes. In these populations, PCS has been linked across studies to processes including endothelial dysfunction, chronic low-grade inflammation, autonomic imbalance, and potential dysregulation of the renin-angiotensin-aldosterone system (RAAS). Persistent cardiovascular, metabolic, and neurocognitive symptoms are reported, but the magnitude and patterns of risk vary across studies, while comparative findings across HTN and DM remain heterogeneous. Symptoms reported frequently include fatigue, cognitive impairment ("brain fog"), and psychological distress, supporting the multisystem complexity of PCS. Although, previous work has indicated that cardiometabolic comorbidities could interact and moderate PCS severity and persistence, there is an important shortfall of both causality and prognosis, as well as the management of PCS. Longitudinal studies are needed for future research regarding risk stratification, disease course, and targeted interventions in individuals with PCS with comorbid high blood pressure and diabetes.}, }

Innate immunity serves as a rapid immune system that can fight off pathogens before they can spread and cause an active infection. Neutrophils, the most abundant innate immune cells, are the first cells to migrate to the site of infection, where they defend against invading pathogens. Once activated at the inflammatory site, neutrophils mediate host protection through multiple mechanisms, including the phagocytosis of pathogens, the release of antimicrobial and pro-inflammatory enzymes, the production of reactive oxygen species (ROS), and the extrusion of their chromatin to form neutrophil extracellular traps (NETs) that bind to extracellular pathogens. Furthermore, neutrophils can move toward the source of the stimulus through a mechanism called chemotaxis, which is mediated by adhesion molecules and chemokine-chemokine receptor axes. However, neutrophil overactivation can have deleterious effects on various organs through the induction of cytokine storms, ROS production, and NET formation. Moreover, the contribution of distinct neutrophil subsets and their plasticity over the course of infection and recovery remain poorly understood. This review summarizes the current knowledge of the interplay between neutrophils and SARS-CoV-2, highlighting the most important mechanisms involved in the pathogenesis of COVID-19, to advance our understanding of this disease.}, }

Although corticosteroids have been proposed as immunomodulatory, controversies surrounding the results of clinical trials have limited their widespread use. This review aims to determine which biomarker-guided corticosteroid treatment for CAP is generally agreed upon in the latest published studies and to discuss the main aspects to be taken into consideration based on lessons learnt from patients with conditions such as influenza, SARS-CoV-2 infection or the recently identified subphenotypes in acute respiratory distress syndrome (ARDS). Most studies have demonstrated that high C-reactive protein concentrations at the time of admission are associated with a hyperinflammatory state and that patients are more likely to benefit from corticosteroid treatment if they have high concentrations. High levels of C-reactive protein (CRP) were used as an inclusion criterion in one clinical trial, demonstrating that treatment failure was reduced in the corticosteroid group. A post-hoc analysis of the results of several studies also showed that CRP levels above 200 mg/L were associated with benefits in patients receiving corticosteroids. Recent guidelines have proposed the use of corticosteroids in patients with severe CAP or septic shock. Corticosteroids could be more beneficial for patients with a hyperinflammatory subphenotype; however, there are currently no prospective studies evaluating this approach. Further studies are needed to clarify the role of biomarkers in personalised medicine for patients with CAP. In the meantime, patients with severe CAP or high CRP levels should be treated with corticosteroids.}, }

These infections can lead to heightened serum IgE levels, which play a vital role in the immune response and the worsening of asthma symptoms. The Th2 inflammatory pathway is frequently upregulated during these infections, associated with increased production of cytokines such as IL-4, IL-5, and IL-13, which aggravate asthma symptoms. Additionally, viral infections can compromise the airway epithelium, resulting in greater exposure to allergens and irritants, and disrupt the balance between Th1 and Th2 cytokines, leading to more severe exacerbations.}, }

The structure and functions of SARS-CoV-2 proteins that may be potential drug targets, including the spike protein, main protease, papain-like protease, RNA-dependent RNA polymerase, host proteins like angiotensin-converting enzyme 2, and transmembrane protease and serine 2, have been thoroughly studied. Biological screening platforms and repurposing have resulted in the discovery of drugs such as nirmatrelvir-ritonavir (Paxlovid), remdesivir (Veklury), molnupiravir (Lagevrio), anakinra (Kineret), vilobelimab (Gohibic), baricitinib (Olumiant), and tocilizumab (Actemra). The present analysis provides details on the pathogenesis, prevention, diagnosis, clinical characteristics, and potential treatment options currently available worldwide.}, }

These subsets orchestrate distinct immune functions that protect the host but can also drive immunopathology when dysregulated. The classical Th1-Th2 paradigm expanded with the discovery of Th17 and Th9 cells, revealing greater diversity and complexity in Th cell biology. Th9 cells, generated under the influence of TGF-β and IL-4, are defined by robust production of interleukin-9 (IL-9). IL-9 is now recognized as a multifunctional mediator produced by Th9 cells, mast cells, ILC2s, Tregs and certain Th17 subsets. Fate-mapping and reporter mouse models have improved our understanding of IL-9-producing immunocytes, though limitations remain in defining temporal and tissue-specific dynamics. As shown earlier, IL-9 promotes mastcell proliferation, mucus hypersecretion, epithelial changes and airway remodelling in allergic inflammation and asthma. Genetic studies have linked IL-9/IL-9 receptor variants to increased susceptibility to allergic diseases such as asthma. Similarly, during respiratory viral infections, including RSV and COVID-19, IL-9 amplifies type 2 inflammation, granulocyte recruitment and mucus production, exacerbating airway obstruction. In fact, emerging evidence implicates a Foxo1-IL-9 axis in COVID-19, where IL-9 enhances lung inflammation and impairs antiviral interferon-stimulated gene responses. Collectively, IL-9 represents a context-dependent driver of virus-induced lung pathology and a promising therapeutic target requiring deeper mechanistic and translational investigation.}, }

The role of GSLs in acute COVID-19 infection is critical but remains less-studied in the sequelae of long COVID (post-COVID condition); because the same enzymes that regulate GSL metabolism are critical for viral entry and exit, neuromuscular junctions, neurological function, and cellular metabolism, it is important to determine whether long COVID may increase the risk of subsequent neurodegeneration. SARS-CoV-2 infection alters lipid metabolism and oxygen use and can bind to and modify the expression of neurotrophic GSLs such as GM1 ganglioside. GM1 (N-acetylneuraminic acid) is human-specific and probably evolved as a result of a pandemic 3-2.5 million years ago that drove its selection. GM1 functions as a coreceptor with angiotensin-converting enzyme 2 for SARS-CoV-2 while also being a neurotrophin. Viral multiplication takes place in the endoplasmic reticulum/Golgi apparatus, where GSLs are synthesized. This review defines the complex interaction between viruses, GSLs, and neurodegeneration, which provides new perspectives on the interlinked metabolic changes. A European working group has been set up to assess the risks of neurodegeneration with long COVID, based on potential GSL-mediated mechanisms. SIGNIFICANCE STATEMENT: The SARS-CoV-2 pandemic has resulted in a large number of subjects living with long-term consequences (long COVID). Glycosphingolipids and gangliosides are involved in both viral infections and neurodegeneration; hence, it is important to evaluate whether long COVID may increase the risk of neurodegeneration via this route. This study is the result of a European consortium formed to evaluate this possibility.}, }

Extensive safety monitoring across randomized clinical trials, national surveillance systems, and global pharmacovigilance programs has consistently supported a favorable benefit-risk profile for these vaccines. Despite this evidence, a range of questions and mechanistic hypotheses continue to circulate, including assertions of increased risk of malignancies, autoimmune diseases, and all-cause mortality, as well as proposed mechanisms involving product-related impurities (e.g. DNA contamination), biodistribution and antigen persistence, non-canonical translation (e.g. ribosomal frame-shifting), and immune modulation. This targeted narrative review synthesizes nonclinical, clinical, pharmacoepidemiologic, and regulatory evidence relevant to these mechanistic and safety related questions. Published literature, regulatory assessments, and surveillance data were qualitatively evaluated in the context of biological plausibility, methodological rigor, and consistency across independent data sources. Across the body of evidence, findings do not support increased long-term mortality, malignancy, autoimmune disease, genotoxicity or other long-term safety issues attributable to mRNA COVID-19 vaccination. On the contrary, several large population-based studies have reported lower all-cause mortality among vaccinated individuals. Residual DNA levels are within established regulatory limits when measured using validated methods, and no credible mechanism supports genomic integration. Biodistribution studies demonstrate expected localization to the injection site and lymphoid tissues with no persistence. Immunologic findings, including IgG4 subclass responses, have not been associated with impaired protection in real-world vaccine effectiveness studies. Collectively, the evidence supports the safety and effectiveness of mRNA COVID-19 vaccines. Ongoing surveillance and rigorous evaluation remain essential to inform public health policy. Importantly, vaccine safety questions should be assessed using transparent, structured frameworks that systematically weigh benefits, harms, quality of evidence, values, and feasibility.}, }

The volume of emerging evidence regarding pulmonary-related PCC complications highlights the urgent need for current, evidence-informed guidelines to ensure timely assessment and effective treatment for those affected by PCC. Thus, the aim of this review was to synthesise existing research on the management and treatment of pulmonary complications in individuals with PCC. A rapid review of published and grey literature focused on pulmonary-related PCC complications was completed in November 2023 and updated in June 2025, in accordance with PRISMA (preferred reporting items for systematic reviews and meta-analyses) guidelines. We identified 73 unique articles, including 12 guidance documents, 24 secondary studies (including 11 systematic reviews with meta-analyses, eight systematic reviews and three scoping reviews) and 37 primary research studies (13 randomised controlled trials) and narratively synthesised their findings. Guidance documents addressed workup and management for pulmonary-related PCC complications, recommending the use of pulmonary function testing with diffusing capacity and the importance of ruling out other conditions. Although evidence regarding the use of medical and pharmacological interventions for treatment of pulmonary-related PCC complications were limited and inconclusive, the current evidence base suggested potential effectiveness of a multidisciplinary rehabilitation approach for pulmonary-related PCC treatment, involving specialist consultations and tailored rehabilitation programmes. The heterogeneity in study quality and risk of bias warrants cautious interpretation of the findings. The current evidence and evolving healthcare landscape suggest the need for updated, evidence-informed clinical guidance.}, }

Chronic high-altitude adaptation (≥ 2,500 m) modifies human pulmonary physiology through hypoxia-inducible factor (HIF-1α/2α) stabilization, ACE2 downregulation, enhanced capillary recruitment, and anti-inflammatory shifts, potentially reducing ARDS severity. Across published observational studies, findings remain heterogeneous; however, several cohorts have reported lower mortality at moderate-to-high altitude (approximately 30–50% in some reports), along with proposed altitude-appropriate SpO2 targets (89–93%) and alternative interpretations of oxygenation indices (e.g., barometric pressure–adjusted P/F ratios). Protection is strongest in younger, comorbidity-free patients, but attenuates in diabetics/hypertensives. In this perspective, we critically examine the evidence on how altitude may influence the clinical course and survival of critically ill patients, exploring potential pulmonary adaptive mechanisms and reflecting on their implications for monitoring and management in intensive care units.}, }

Here, we provide a comprehensive, PTM-centric synthesis of SARS-CoV-2 pathogenesis, detailing how phosphorylation, ubiquitination, SUMOylation, glycosylation, acetylation, succinylation, ISGylation, and ADP-ribosylation cooperatively shape virus-host interplay. We dissect the mechanistic roles of individual modifications, such as phosphorylation-mediated transitions in nucleocapsid function, ubiquitin-driven degradation of immune factors, and SUMOylation-guided viral assembly, while revealing higher-order regulatory circuits and crosstalk among PTMs. Additionally, we highlight emerging computational tools for PTM site prediction and identify shared enzymatic nodes exploitable for host-directed antiviral strategies. This integrative framework positions PTMs as not merely bystanders but as central modulators of viral fitness and host vulnerability, offering novel avenues for therapeutic intervention against SARS-CoV-2 and future pandemic threats.}, }

A comparative analysis reveals distinct organizational models: the ECDC operates within European Union (EU) institutional frameworks emphasizing functional specialization; the Africa CDC employs decentralized Regional Coordination Centers; and the Gulf CDC implements hybrid governance via Permanent Communication Networks. Each model offers valuable lessons for ACPHEED's development, particularly concerning governance structures that balance regional coordination with national sovereignty. ACPHEED faces unique challenges due to ASEAN's consensus-based, nonlegislative institutional nature and its tri-country operational structure. Critical success factors include phased surveillance emphasizing a defined scope and capacity building; inclusive governance mechanisms ensuring equitable member-state ownership; and operational frameworks applying subsidiarity principles to complement existing ASEAN mechanisms. Sustainable financing remains paramount given ASEAN's limited budgetary authority. Japan's strategic partnership should capitalize on its technical expertise in laboratory systems, digital surveillance, and disaster preparedness through comprehensive institutional support. ACPHEED's success depends on sustained political commitment, realistic financial arrangements, and effective integration into global health security architectures.

Of the several randomized controlled trials studying the efficacy of remdesivir, the vast majority were studied on the adult population. Results remain contradictory, with some studies supporting the high efficacy of remdesivir while others highlighting the lack of significance of its antiviral effects. Given the lack of focus on the pediatric population, the antiviral effects of remdesivir in cardiac pediatric patients, who are particularly vulnerable, remain especially under-investigated. This literature review explores current literature on remdesivir's mechanism of action and efficacy against COVID-19, especially in the pediatric cardiac population.

VLPs are self-assembled nanostructures composed of viral structural proteins that mimic native virions without carrying genetic material, while virosomes are reconstituted viral envelopes that retain functional glycoproteins but lack a nucleocapsid. Both systems provide strong immunogenicity and safety by mimicking viral architecture while eliminating the risk of replication.

This increases the demand for real-world evidence to complement findings from randomized controlled trials. The German IQVIA Disease Analyzer (DA) database, which is populated with anonymized electronic medical records from general practitioners and specialists, has become an increasingly valuable source for cardiovascular research. Over the past two decades, and especially between 2020 and 2025, numerous epidemiological studies have used this database to explore associations between cardiovascular risk factors, comorbidities, therapeutic patterns, and cardiovascular outcomes in large, broadly representative outpatient populations. This review synthesizes evidence from 13 selected DA-based studies examining atrial fibrillation, heart failure, cardiometabolic disease, lipid management, non-alcoholic fatty liver disease (NAFLD)-related cardiovascular risks, cerebrovascular complications, COVID-19-associated vascular events, and modifiable behavioral and anthropometric factors. These studies were selected based on predefined criteria including cardiovascular relevance, methodological rigor, large sample size, and representativeness of key disease domains across the 2000-2025 period. Eligible studies were identified through targeted searches of peer-reviewed literature using the German IQVIA Disease Analyzer database and were selected to reflect major cardiovascular disease domains, risk factors, and therapeutic areas. Across disease domains, the reviewed studies consistently demonstrate the DA database's capacity to identify reproducible associations between cardiometabolic risk factors, comorbidities, and cardiovascular outcomes in routine outpatient care. While causal inference is not possible, the database enables the identification of clinically meaningful associations that inform hypothesis generation, help quantify disease burden, and highlight gaps in prevention or treatment. The database's strengths include large sample sizes (often exceeding 100,000 patients), long follow-up periods, and high external validity, while limitations relate to coding accuracy, residual confounding, and the absence of detailed clinical measures. Collectively, the evidence underscores the importance of the DA database as a crucial platform for real-world cardiovascular research.}, }

They can be activated in a TCR-dependent manner by ligands presented on the monomorphic protein MHC class I-related protein 1 (MR1) which is found on many cell types, including professional antigen presenting cells (APCs) and epithelial cells. This has sparked interest in the potential to exploit the MR1-MAIT cell axis for the development of vaccines against infectious disease. Within this context an MR1 ligand, typically 5-(2-oxopropylideneamino)-d-ribitylaminouracil (5-OP-RU), is administered with or without a Toll-like receptor (TLR) ligand or cytokine in a pan vaccination approach that would prime the immune response to provide protection against a variety of bacterial and viral pathogens. This strategy has led to enhanced protection in murine models of Legionella longbeachae, Francisella tularensis, Klebsiella pneumoniae, Streptococcus pneumoniae and influenza infection. However, studies against Mycobacterium tuberculosis infection have proven less successful. The second vaccination approach involves pairing the MR1 ligand with more conventional antigens that could activate CD4[+] and/or CD8[+] T cells. This approach has been successful in murine models of cholera, influenza, and SARS-CoV-2, including in the context of subunit vaccines. However, there are several challenges when using MR1-MAIT cell-mediated vaccine adjuvants.

This narrative review examines strategies designed to improve vaccine uptake among non-pregnant adults aged ≥18 years and inform future adult vaccination strategies. We conducted a targeted literature search using keywords for vaccination, respiratory diseases, strategy/program/implementation, and adults in PubMed database and CDC, WHO, and ECDC websites, between 2014 and 2024. A snowball search of literature reviews and key references was also performed to identify additional relevant studies. Eligible publications focused on vaccination strategies against influenza, COVID-19, and pneumococcal disease targeting non-pregnant adults (≥18 years). We categorized the strategies by intervention type to describe their influence on vaccination campaigns and vaccine uptake/coverage. We included 45 publications, encompassing strategies focused on individual decision-making, healthcare system functions, and national policy. Educational and awareness interventions (such as healthcare worker/provider recommendations during consultation, phone calls, letters, text messages, and social media outreach) reportedly raised vaccination rates. Access-related factors, including convenient vaccination sites and free or subsidized vaccines, were reported to be important factors in improving coverage in underserved communities. Within healthcare settings, strategies such as continuous vaccine provider training and workflow/process optimization were shown to enhance vaccination delivery. At the local or national policy levels, legislation governing program targets shaped immunization efforts and facilitated collaborations and partnerships to expand campaign reach. The findings may inform policymakers and public health/immunization practitioners in designing context-specific immunization initiatives that effectively reach adult populations.}, }

Originating in 2016 and rapidly evolving since, ST has transformed infectious disease research by mapping host-pathogen interactions directly within intact tissues. Current platforms fall into two categories: sequencing-based methods (Visium, GeoMx, Stereo-seq) offering whole-transcriptome coverage at modest resolution and imaging-based platforms (Xenium, CosMx, MERFISH) providing single-cell or subcellular detail with targeted gene panels. These technologies reveal spatially organized immune responses, local tissue remodeling, and pathogen niches across viruses, bacteria, and parasites. In viral infection, ST uncovered heterogeneity in COVID-19 lung microenvironments, spatial immune activation in lymphoid tissues, and variant-specific inflammatory patterns. In bacterial disease, ST delineated granuloma architecture in tuberculosis and mapped vaccine-induced lung responses in Shigella studies. Parasitic infection studies identified localized inflammatory hotspots and microenvironmental control of T-cell differentiation in malaria. Despite powerful insights, ST faces constraints including RNA quality limitations, tradeoffs between resolution and transcript breadth, high cost, and analytical complexity. Nonetheless, ST increasingly informs vaccine design by identifying tissue-specific immune programs and protective microenvironments and is poised to become a standard tool for infectious disease biology.}, }

The identification, selection, and rational redesign of conserved viral epitopes constitute the direct immunological foundation of universal SARS-CoV-2 vaccine development. The breadth and durability of protection are therefore primarily determined at the level of antigen and epitope design, whereas adjuvants, delivery platforms, and routes of administration serve as enabling and amplifying components rather than primary drivers of universality. Accordingly, this review discusses key determinants of universal vaccine design, including antigen selection, adjuvant utilization, and route of administration. The spike protein, particularly its receptor-binding domain, is a major antigenic target, but its high mutation rate challenges long-term vaccine efficacy. Strategies focusing on conserved epitopes in antigen designs show potential to elicit cross-neutralizing immune responses. Nanoparticle-based vaccines capable of presenting multiple homologous or heterologous antigens have demonstrated enhanced immunogenicity, broad protection in preclinical models and safety in clinical trials. The addition of next-generation adjuvants further amplifies humoral and cellular immunity beyond the capabilities of traditional aluminum-based adjuvants. Moreover, mucosal vaccine delivery may provide superior local protection at viral entry sites and limit transmission. Importantly, integrating these technological advances with epitope-centered antigen design and immunological data from vaccinated individuals will accelerate the identification of conserved epitopes and inform future vaccine design. A multidisciplinary approach combining optimized antigen engineering, novel adjuvant systems, and innovative delivery strategies is essential for the realization of a broadly protective universal SARS-CoV-2 vaccine.}, }

Enterovirus-associated hand-foot-and-mouth disease (HFMD) is the most frequently reported cause.

Additionally, cases of onychomadesis linked to other viral infections, including KRM1-independent enteroviruses, influenza virus, SARS-CoV-2, varicella-zoster virus, and co-infections involving HIV and mpox, have also been documented. Despite growing recognition of the virus-induced onychomadesis, in most cases the exact pathogeneses are yet elusive, thereof lack of approved treatments.

Ambiguities in equity commitments, geopolitical fragmentation and rising nationalism threaten effective implementation. For Africa, realising the treaty's promise requires robust legal frameworks, enhanced manufacturing and regulatory capacities and sustainable financing mechanisms that reduce donor dependency. This analysis critically examines the treaty's provisions and political economy, emphasising the need for enforceable obligations, continental leadership and multi-sectoral accountability.

Also, while it is generally known that genomic surveillance of SARS-CoV-2 largely declined following the end of the COVID-19 public health emergency, this has not been formally measured, and how it impacts our ability to detect and characterize new variants, remains unknown. Therefore, we performed an analysis of SARS-CoV-2 sequence submissions on the Global Initiative for Sharing All Influenza Data (GISAID) platform from 2020 to 2025, by country and World Bank income classification. There were large differences in SARS-CoV-2 sequence submissions by income classification, indicating a disparity in our ability to monitor SARS-CoV-2 evolution worldwide, which has important consequences for preventative measures such as vaccine strain selection. Nevertheless, there are important barriers to sustainable sharing of SARS-CoV-2 sequence data, which we discuss in detail, along with their relevance to other pathogens of public health importance. Also, the decrease in sequence submissions in high income countries from 577 million at the peak of the pandemic, to under 50 million in 2024, represents a loss of capacity to monitor SARS-CoV-2 evolution in countries with known capabilities. Ultimately, data drive the impact of genomic epidemiology, and long-term investments in genomic surveillance programs, as well as incentives for timely data sharing, are urgently needed to detect and characterize new viral variants worldwide.}, }

Although these diseases are caused by different pathogens, they share important host-related determinants of severity, including immune dysfunction, oxidative stress, endothelial injury, and maladaptive inflammatory responses. Glutathione, the primary intracellular antioxidant and a key regulator of redox balance, has emerged as an important host factor connecting these processes across infectious diseases. This review integrates experimental, translational, and clinical evidence supporting the role of glutathione in regulating immune function, oxidative stress, and tissue damage in tuberculosis and COVID-19. In tuberculosis, glutathione deficiency compromises macrophage antimicrobial activity, disrupts granuloma structure, and alters T helper cell responses, leading to impaired immune containment and disease progression. In COVID-19, reduced glutathione levels are associated with redox imbalance, excessive cytokine signaling, endothelial dysfunction, and thromboinflammatory complications, especially in high-risk populations. In both diseases, glutathione depletion reduces host resilience and increases vulnerability to severe outcomes through shared immune and vascular pathways. By unifying disease-specific findings within a host-directed framework, this review highlights glutathione and redox signaling as common vulnerability pathways that help explain overlapping risk profiles for severe tuberculosis and COVID-19. It also places glutathione biology within the broader context of host-directed immunotherapy, emphasizing its potential role in prevention-focused and resilience-based strategies that complement pathogen-targeted treatments. Although current evidence does not support simple claims of disease prevention, it provides strong mechanistic justification for further investigation of glutathione as a modifiable host factor in high-risk populations.}, }

One proposed mechanism is the long-lasting dysregulation of the immune complement system. This systematic review is the first to summarize the current evidence and evaluate the potential role of long-lasting complement activation in people with long COVID. Methods: A systematic electronic search on PubMed, MEDLINE, CINAHL, and Embase was conducted up to 15 October 2025, to identify studies investigating complement activation in people with the post-COVID-19 condition. The Newcastle-Ottawa Scale was used to evaluate the risk of bias and methodological quality. Results: Among the 247 studies initially identified, eleven met the inclusion criteria, comprising 1435 individuals (age: 48.5 years, 70% females) with long COVID and 1124 controls (age: 43.6 years, 60% females). All studies were of a high quality, with scores ranging from 7 to 8 stars (mean: 7.6 ± 0.5). The activation of the classical complement pathway was investigated in nine studies, whereas the lectin, alternative, and terminal complement pathways were each assessed in three studies. Multiple studies investigated several complement pathways. The results were heterogeneous since several markers of complement activation spanning the classical (C2, C4a, C4b, and C1s-C1INH), alternative (Ba, iC3b, and Factor D), and terminal (C5bC6, C5a, C9, and TCC) pathways were elevated, whereas other markers were not significantly different (C3, C4, and C4d) between patients with/without long COVID. In addition, markers spanning the lectin complement pathway (MBL, and MASP1-C1INH) were not significantly different between individuals with and without long COVID. Conclusions: The current evidence suggests potential long-lasting complement system dysregulation in individuals with long COVID, although the clinical significance remains controversial, due to heterogenous findings. Specific post-COVID symptom clusters, such as fatigue, dyspnea, or brain fog, have been linked to a distinct pattern of complement dysregulation. Substantial methodological heterogeneity, including differences in follow-up periods, complement markers, assessment methods, and control groups, along with the small number of available studies, underscores the need for further research to clarify the mechanisms linking complement dysregulation to long COVID.}, }

The primary objective of this article is to synthesize evidence on the prevalence of burnout and PTSD among healthcare workers before and during the COVID-19 pandemic. The secondary objectives are: (a) to examine the mechanisms and empirical evidence linking clinician mental health to medical errors and patient safety outcomes and (b) to analyze the medico-legal implications of this relationship, including malpractice liability, institutional responsibility, and opportunities for policy reform. Materials and Methods: We conducted a narrative review searching PubMed (November 2025-January 2026) using predefined keyword combinations. Inclusion criteria comprised original research, systematic reviews, and meta-analyses examining mental health outcomes or patient safety among clinical staff. Data were synthesized narratively across five thematic domains. Results: Burnout prevalence increased from approximately 32% pre-pandemic to 46-52% during peak periods, with emotional exhaustion reaching 67.5% in some settings. PTSD rates rose to 24-34% among frontline staff, exceeding pre-pandemic levels of 15-20%, with ICU staff particularly affected (27-40%). Substantial overlap exists between conditions (86-98% comorbidity). Physician burnout is associated with 2.72 times higher odds of self-reported errors (95% CI: 2.19-3.37), with each point increase in emotional exhaustion raising the error risk by 5-11%. Mechanisms include cognitive impairment (reduced executive function, g = -0.39; impaired working memory, g = -0.36) and sleep disturbance. Malpractice litigation compounds psychological harm, increasing depression and suicidal ideation. Conclusions: This review, synthesizing data from over 500,000 healthcare workers, demonstrates bidirectional relationships among burnout, PTSD, and medical errors with significant medico-legal ramifications.

We conducted a systematic review and meta-analysis of observational cohort studies (both prospective and retrospective) to quantify the impact of chronic hyperglycemia and glucose instability on disease severity, intensive care requirements, and mortality in patients with COVID-19. Materials and Methods: We searched PubMed, Scopus, and Web of Science from January 2020 to October 2024 for observational cohort studies reporting clinically relevant COVID-19 outcomes stratified by glycemic control or GV. Dysglycemia definitions varied across studies (HbA1c-based chronic hyperglycemia, fasting glucose, or admission/in-hospital hyperglycemia). GV was assessed using metrics including mean amplitude of glycemic excursions (MAGE), standard deviation (SD), coefficient of variation (CV), or maximum daily glucose difference. Twelve studies met inclusion criteria and were included in qualitative synthesis; five studies were eligible for quantitative synthesis of clinical outcomes. Random-effects DerSimonian-Laird models were applied due to anticipated clinical heterogeneity. Heterogeneity was evaluated using Cochran's Q, τ[2], and I[2] statistics. Results: Overall, 12 observational studies (9 prospective and 3 retrospective cohorts; n = 1,008,310 patients) were included. In quantitative analyses of five eligible cohorts, poor glycemic control was associated with a significantly increased risk of severe or critical COVID-19 (pooled RR = 1.75, 95% CI: 1.45-2.11; I[2] = 29%), ICU admission (RR = 1.54, 95% CI: 1.18-2.01), and mechanical ventilation (RR = 1.72, 95% CI: 1.31-2.26). Three studies evaluating GV demonstrated a strong association with adverse outcomes (pooled RR = 2.07, 95% CI: 1.71-2.50; I[2] = 0%); this low heterogeneity should be interpreted cautiously given the limited number of studies. GV remained associated with mortality in multivariable models, indicating that glycemic variability is separately associated with mortality as a clinically relevant prognostic risk marker in hospitalized COVID-19 patients. Conclusions: Both chronic hyperglycemia and elevated glycemic variability are each associated with increased risk of severe COVID-19 outcomes. Glycemic variability appeared to be a consistent, low-heterogeneity prognostic marker of mortality, being separately associated with higher death risk in hospitalized COVID-19 patients, highlighting its potential utility as a dynamic metabolic biomarker. Early identification and targeted management of dysglycemia-especially glucose instability-may improve prognosis in hospitalized COVID-19 patients. PROSPERO: CRD420251250718.}, }

Myocardial injury in COVID-19 results from a complex interplay between direct viral effects and immune-mediated inflammation, supported by histopathological studies revealing macrophage-rich infiltrates, microthrombosis, and supporting fibrosis in isolated areas. In contrast, vaccine-associated myocarditis-reported predominantly following mRNA vaccines-has a self-limiting clinical course, with mechanisms likely involving molecular mimicry, aberrant immune activation, or hypersensitivity reactions, although these pathways require further validation. Although mRNA vaccines have been associated with a small increase in myocarditis, particularly in young men, the risk is significantly lower than that associated with COVID-19 infection, and the cardiovascular benefits of vaccination far outweigh these rare adverse events in most populations. After the end of the pandemic, the number of patients with severe forms of COVID-19 has decreased significantly, but we consider that cardiac involvement remains an important issue for the acute and long-term prognosis of patients with SARS-CoV-2 infection.

Alcohol showed a pooled prevalence of 36.2 percent, cannabis 48.1 percent, and tobacco 11.5 percent. Suicidal ideation was the most frequent outcome, with a pooled prevalence of 36.8 percent among substance users. Most studies reported an increased association between substance use and suicidal behavior compared with pre-pandemic periods. Conclusions: Substance use and suicidal behavior frequently co-occurred during the COVID-19 pandemic, particularly suicidal ideation and alcohol use. These findings highlight the need for integrated mental health and substance use interventions during public health crises.}, }

Respiratory physiotherapy is commonly used to support patients with pulmonary conditions. This systematic review aimed to evaluate the effects of the incentive spirometer on cardiopulmonary, functional and patient-reported outcomes in adults during the acute and post-COVID-19 phases. Methods: A systematic literature search was conducted in PubMed, CINAHL, Scopus, Clinical Trials.gov and Google Scholar to identify studies published between January 2020 and April 2025. Owing to substantial heterogeneity in study design, populations, interventions and outcome measures, quantitative synthesis was not feasible and findings were synthesized narratively. Results: Twelve studies involving 573 participants were included. Within-group analyses showed improvements in pulmonary outcomes (including FEV1, FVC, and oxygen saturation), reductions in dyspnea, and improvements in quality of life following incentive spirometer. Improvements in pulmonary function were reported primarily in post-COVID-19 populations, whereas reductions in anxiety and improvements in quality of life were reported mainly in acute COVID-19 settings. Between-group comparisons demonstrated statistically significant differences in favor of the incentive spirometer for selected pulmonary and functional outcomes (including FVC, DLCO, oxygen saturation, six-minute walk test, and 30 s sit-to-stand test), while no significant differences were observed for other outcomes such as peak expiratory flow, respiratory rate, or heart rate variability. Randomized controlled trials were judged to have a moderate risk of bias, non-randomized studies a moderate-to-serious risk, and certainty of evidence ranged from very low to moderate. Conclusions: Incentive spirometer may support respiratory, functional, and psychological recovery in adults during the acute and post-COVID-19 phases. However, effects vary across outcomes and comparator interventions, and the overall certainty of evidence is low to moderate. Further high-quality research is required to confirm effectiveness and guide optimal clinical use.}, }

MPXV has spread at a rapid pace during the COVID-19 pandemic, causing 10,000+ confirmed cases and ~300 fatalities in 122 countries. This virus comprises two major clades, Clade I (Central African), which is evidently more virulent, and Clade II (West African), which has caused the recent outbreaks across the world and caused fewer deaths. Clinically, Mpox presents as a milder form with fever, lymphadenopathy, and vesiculopustular rash similar to smallpox. Diagnostic measures such as polymerase chain reaction (PCR) are the main diagnostic confirmatory tools. Advanced diagnostics involve electronic microscopy, serology, and immunohistochemistry. Alternative drugs like tecovirimat and brincidofovir have demonstrated potential for treating smallpox, but there is scanty evidence on their efficacy against MPXV. Most recent advancements in the study of vaccines have resulted in the creation and introduction of MVA-BN (JYNNEOS/Imvanex/Imvamune) and ACAM2000 vaccines, which conferred cross-protection against MPXV. MVA-BN is suggested to perform better than other types due to its enhanced safety and immunogenicity. Researchers are also developing DNA and protein subunit vaccines against Mpox to induce specific immune responses by presenting viral proteins. The discovery of novel vaccine candidates and antiviral treatments will be needed to prevent future outbreaks and reduce the global health burden of Mpox. This review focuses on the characterization of MPXV, summarizing current knowledge on its genomic structure, pathogenesis, replication, potential targets of anti-MPXV drugs, clinical features, and epidemiological patterns, along with recent advances in vaccine development.}, }

As healthcare systems face increasing demand and the need for cost-effective care delivery, teletriage services have expanded, particularly following the COVID-19 pandemic. Objective: This narrative review examines the current state of nurse teletriage practice, its effectiveness, safety outcomes, and implementation considerations. A comparative analysis with physician-led teletriage models is provided, and the emerging role of artificial intelligence is explored. Methods: A narrative review of the literature was conducted through searches of multiple databases including PubMed/MEDLINE, CINAHL, Cochrane Library, Embase, Web of Science, and Google Scholar. This approach was selected due to the heterogeneous nature of the teletriage literature, which spans diverse study designs, populations, and outcomes that are not amenable to formal systematic synthesis. Peer-reviewed articles published between 1970 and 2024 examining safety outcomes, effectiveness, and implementation frameworks were reviewed. Results: The available evidence suggests that nurse-led teletriage systems, particularly when supported by computerized decision support systems, can improve patient access to care while maintaining safety standards. Studies indicate that telephone triage nursing does not increase mortality, hospitalization rates, or emergency department referrals when properly implemented. One well-documented physician-led model in Israel reported diagnosis accuracy rates of 98.5% and decision reasonableness rates of 92%, though generalizability across settings requires caution. Key success factors appear to include the use of evidence-based protocols, staff training, technology infrastructure, and quality assurance programs. While these findings are promising, the heterogeneous nature of the included studies and absence of formal quality assessment warrant cautious interpretation. Conclusions: Nurse teletriage appears to be an effective and safe approach to healthcare delivery that addresses challenges in modern healthcare systems. The choice between nurse-led and physician-led models should consider population complexity, case types, available resources, and economic factors. Artificial intelligence technologies offer potential opportunities to enhance teletriage, though careful validation is essential. Future research should focus on long-term outcomes, comparative effectiveness across healthcare systems, and rigorous evaluation of AI applications. Highlights: Telephone triage services, where nurses or physicians assess patients remotely and guide them to appropriate care, have become increasingly important in modern healthcare. This narrative review examines the evidence on nurse-led telephone triage, comparing it with physician-led models and exploring emerging technologies like artificial intelligence. The available evidence suggests that nurse-led systems, when supported by appropriate protocols and training, can safely improve patient access to care while reducing healthcare costs. Physician-led models may offer advantages for complex cases but at higher costs. While artificial intelligence shows promise for enhancing triage accuracy, current evidence specific to telephone triage remains limited. Healthcare organizations should carefully consider their population needs, available resources, and local context when implementing teletriage services.}, }

This narrative review summarizes current evidence on the immunological, clinical, and preventive effects of vitamin D in the context of novel coronavirus disease (COVID-19), post-acute sequelae of SARS-CoV-2 infection (long COVID), and influenza. Mechanistically, vitamin D enhances innate immune defenses through the induction of antimicrobial peptides, including cathelicidin and defensins, and modulates adaptive immunity by suppressing maladaptive Th1/Th17 responses while promoting regulatory T-cell activity. Observational studies have frequently associated vitamin D deficiency with more severe COVID-19 outcomes; however, these associations may be influenced by confounding factors and reverse causality. Some meta-analyses suggest that vitamin D supplementation reduced rates of intensive care unit admission and ventilatory support, particularly among older adults and individuals with low baseline serum 25-hydroxyvitamin D concentrations. Emerging evidence also indicates that inadequate vitamin D status may be associated with an increased risk and symptom burden of long COVID, although causality has not been established. In the case of influenza, a limited number of randomized controlled trials (RCTs) and meta-analyses report a modest but statistically significant reduction in infection risk, especially with daily or weekly vitamin D supplementation in populations with low baseline vitamin D levels. Clinical guidelines consistently recommend maintaining adequate vitamin D status for general health but do not endorse high-dose vitamin D as a treatment for COVID-19 due to inconsistent trial findings. Overall, vitamin D should not be considered a standalone therapeutic agent; rather, maintaining sufficient vitamin D levels represents a low-risk, potentially beneficial strategy to support immune resilience against respiratory viral infections.}, }

However, growing evidence over the last decade has radically changed this paradigm, revealing platelets as dynamic immune and inflammatory effectors that actively participate in host-pathogen interactions. In viral infections, platelets are not merely innocent bystanders but represent key players in a bidirectional and tightly regulated platelet-virus axis that influences viral dissemination, immune activation, endothelial dysfunction, and the development of thrombotic and hemorrhagic complications. Several clinically relevant viruses, including SARS-CoV-2, influenza virus, HIV, dengue virus, and viral hemorrhagic fever-associated pathogens, have been shown to directly or indirectly interact with platelets through surface receptors, immune complexes, and inflammatory mediators, leading to platelet activation, phenotypic reprogramming, and accelerated clearance. These processes contribute to the paradoxical coexistence of thrombocytopenia and hypercoagulability that characterizes many severe viral diseases. Moreover, platelets can act as immune sentinels by sensing viral components, releasing cytokines and chemokines, forming platelet-leukocyte aggregates, and modulating both innate and adaptive immune responses, thereby shaping the clinical course of infection. In this review, we synthesize current evidence on the molecular and cellular mechanisms governing virus-platelet interactions, with particular emphasis on their role in immune-thrombosis, endothelial injury, and organ dysfunction. We further discuss the clinical implications of platelet dysregulation in viral infections, including its potential value as a biomarker of disease severity and as a therapeutic target. Understanding the platelet-virus axis provides a unifying framework to explain the thrombo-inflammatory phenotype of viral diseases and may open new avenues for risk stratification and targeted interventions in affected patients.}, }

Although clinical surveillance provides direct and reliable results, it has limited applicability. Wastewater-based epidemiology (WBE) has therefore emerged as a valuable, non-invasive complementary tool for disease surveillance. It provides a comprehensive picture of virus circulation in a population, including asymptomatic individuals and those who do not seek healthcare. In addition, it facilitates early detection of outbreaks and the collection of epidemiologic data at the community level. However, WBE also presents technical challenges, including variations in sampling and testing protocols, the presence of inhibitors that affect viral RNA extraction, and the need for standardised procedures between studies. These challenges should be addressed for possible future infectious disease outbreaks. One of the challenges facing researchers was to develop efficient methods that could overcome the extraction and detection problems related to inhibitors present in wastewater. To this aim, this systematic review highlights the potential use of WBE, the variety of techniques, and the most effective methods for the detection and quantification of SARS-CoV-2 in wastewater samples. A reproducible electronic search of the literature was conducted in the Web of Science (WoS) and PubMed databases for articles published between 2020 and 2024. Our search revealed that the majority of observed WBE applications emphasised a correlation between SARS-CoV-2 RNA concentration trends in wastewater and epidemiological data. Another relevant issue that the articles often discussed and compared was the techniques used in different steps of sample processing, such as sample collection, concentration and detection, hence the lack of standardised procedures. This paper provides a framework regarding previous research on WBE to gain a better understanding that will lead to functional solutions.}, }

In this review, we provide a comprehensive and technology-driven overview of cutting-edge formulation and manufacturing strategies for pulmonary drug delivery, with particular emphasis on the key process and formulation parameters required to generate effective inhalable systems for the treatment of infectious diseases. Advanced particle-engineering approaches, including spray drying, spray freeze drying, jet milling, and supercritical fluid technologies are discussed as enabling tools to tightly control aerodynamic particle size, morphology, and solid-state properties. In parallel, emerging platforms such as nanoparticle-based delivery systems are examined for their ability to target specific lung cell populations, including epithelial cells and alveolar macrophages, thereby enhancing antimicrobial efficacy. Finally, innovative manufacturing concepts such as microfluidics and three-dimensional (3D) printing are highlighted as promising strategies to improve particle size uniformity, reproducibility, and formulation customization.

Emerging evidence shows that epithelial-mesenchymal transition (EMT) acts as a key factor in the pathogenesis of this idiopathic interstitial lung disease by connecting long-lasting epithelial damage to fibroblast accumulation and fibrotic processes. Viral pathogens, particularly emerging and re-emerging viruses, such as Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), Influenza Virus, and Dengue Virus (DENV) and also those with oncogenic potential such as Epstein-Barr Virus (EBV), Cytomegalovirus (CMV), and Hepatitis C Virus (HCV), have been demonstrated to be significantly associated with impaired epithelial signalling, persistent inflammation, and EMT induction. This underscores the presence of potential mechanistic overlap between viral infections and fibrotic complications of the respiratory system. On the other hand, investigations have also suggested the capacity of Traditional Chinese Medicine (TCM) agents to modulate various EMT-linked pathways, which are simultaneously involved in both viral infections and IPF development. These common signalling pathways include TGF-β, Wnt/β-catenin, PI3K/AKT, and NF-κB signalling, acting as potential therapeutic targets against fibrotic complications such as IPF. The present review aims to comprehensively describe current evidence on the dynamic cross-talk between viral pathogens, particularly SARS-CoV-2, Influenza Virus, and DENV, EMT, and lung fibrosis. Additionally, it critically discusses how TCM-derived bioactive agents can interfere with these interconnected processes.

Patients with an altered sense of smell due to anatomical malformations, trauma, neurodegenerative diseases, surgery, or intranasal lesions were excluded from the study.<br><br>RESULTS: Five studies with 131 participants were included. There were 131 participants, of whom 63 were men and 68 were women. The participants' ages ranged from 16 to 56 years. Almost all studies used a dose of 40 IU, except one that used different doses for different participants. Glycemic assessment was performed in three studies, which showed a very slight decrease in glucose, except in one study in which the drop in glucose reached 10.4 mg/dL. All studies agreed that olfactory function improved after INI administration.<br><br>CONCLUSION: This systematic review concluded that INI can be an effective treatment option for patients with OD. However, further well-designed clinical trials are required to establish robust clinical recommendations.}, }

Influenza, pneumococcal pneumonia, and respiratory syncytial virus infections account for a significant proportion of typical infectious complications and are preventable by vaccination. The immune system is weakened in CKD, reducing vaccination efficacy. Additionally, some patients with CKD receive immunosuppressive medications. The reduced seroreactivity to various vaccines must be considered when selecting vaccines, vaccine doses, and schedules for patients with CKD. Vaccinations are generally safe in CKD and should be widely used in accordance with public health recommendations to reduce morbidity. Immunosuppression after kidney transplant further impairs vaccination responses. Nevertheless, vaccinations can still be effective and provide protection in a relevant number of patients. Patients who have received transplants should generally not receive live vaccines because of the risk of vaccine-induced complications. Vaccination is usually recommended 6 months after transplant, when immunosuppression is less intense than in the early months. This approach may conflict with seasonal vaccinations, which are often omitted. Data show that at least the influenza vaccination can be administered as early as 4 weeks after transplant without additional risk. In all patients with CKD or posttransplant status, omitting recommended vaccinations is a missed opportunity to prevent relevant infectious complications.}, }

However, no study has ever explored whether there is a true therapeutic difference across the populations or these discrepancies are due to additional confounders. Against this background, we performed a systematic review and meta-analysis of randomized trials of colchicine in patients with CAD. The primary endpoints were trial-defined major adverse cardiovascular events (MACE) and serious adverse events (SAEs). Secondary endpoints included all-cause death, measures of ischemia (cardiovascular death, myocardial infarction [MI], any revascularization, stroke) and measures of safety (serious infections or sepsis and gastrointestinal adverse events). All analyses included an interaction term for the clinical presentation. Sensitivity analyses were performed to explore sources of heterogeneity. After literature search, 20 trials encompassing a total of 21,486 patients (65.4% ACS) were included. Colchicine significantly reduced MACE (incidence rate ratio [IRR]: 0.70; 95% CI 0.55-0.87) without increasing risk for SAEs. Colchicine also reduced MI (IRR 0.81; 95% CI 0.70-0.94) and any revascularization (IRR 0.71; 95% CI 0.51-0.99), while increasing the risk of gastrointestinal adverse events (IRR 1.68; 95% CI 1.23-2.28). No statistically significant interaction was noted for clinical presentation for any endpoint, but a significant interaction for the drug dosage administered and the relationship with the COVID-19 pandemic was noted. In conclusion, the use of colchicine in patients with CAD reduces MACE without significantly increasing SAEs compared to control, although increasing gastrointestinal adverse events, without interaction by clinical presentation.}, }

A comprehensive search of major databases (PubMed/MEDLINE, PsycINFO, Web of Science, CINAHL, and Embase) was conducted and supplemented with citation chaining to identify eligible reports spanning January 1st 2020 up to March 18th, 2025. Article screening, full-text review, and data extraction were completed by two independent investigators. Study quality was assessed using the NIH tool for quantitative studies and the Critical Appraisal Skills Program (CASP) framework for qualitative studies.<br><br>RESULTS: A total of 10,005 identified reports were screened, with seven fair-to-good eligible studies included in the final review. Both quantitative (n&#x2009;=&#x2009;4) and qualitative (n&#x2009;=&#x2009;3) studies were included, and spanned multiple states, with most studies (n&#x2009;=&#x2009;3, 42.9%) conducted in California. Healthcare workers reported various mental health conditions such as depression (48%), anxiety (18.8-51.1%), sleep disorders (17.4%), burnout (47.2%) and PTSD (49.3%), albeit significant heterogeneity constrains comparative analysis. Qualitatively, workers experienced considerable isolation, personality shifts, and cognitive dissonance. Risk factors predictive of mental health conditions included increased workload (&#x3b2;&#x2009;=&#x2009;0.18, p&#x2009;<&#x2009;0.001), workplace conflict (&#x3b2;&#x2009;=&#x2009;0.15, p&#x2009;<&#x2009;0.001), female sex (&#x3b2;&#x2009;=&#x2009;0.10, p&#x2009;=&#x2009;0.04), younger age, chronic medical conditions (&#x3b2;&#x2009;=&#x2009;0.09, p&#x2009;=&#x2009;0.03), fears around COVID-19 (&#x3b2;&#x2009;=&#x2009;0.14, p&#x2009;<&#x2009;0.001), and a lack of pandemic safety training (p&#x2009;=&#x2009;0.033). Protective factors included resilience, administrator and peer support, access to needed resources, and a sense of fulfilment and purpose from working with populations in forensic-correctional settings.<br><br>CONCLUSIONS: Systemic reforms including decreased mandatory overtime, staffing, workload distribution, organizational support, training, improved communication, access to adequate resources and psychosocial interventions may help promote wellness and optimize the ability of healthcare workers to provide care in forensic-correctional settings.

Neutralising antibodies (nAbs), along with vaccines and small-molecule drugs, are among the most promising treatments and prevention options against coronaviruses. Here, we focus on Middle East Respiratory Syndrome coronavirus (MERS-CoV) and discuss receptor usage and current progress in antibody research against MERS-CoV infections. First detected in Saudi Arabia and Jordan in 2012, MERS-CoV is a lethal zoonotic pathogen. MERS-CoV infections have been reported by 27 countries between April 2012 till now, with 953 deaths (∼35% mortality) (5 new infections and 4 fatalities reported as of 1 October 2024). WHO identified MERS-CoV as a high-threat pathogen due to its severity, high mortality rate, and potential for epidemic or pandemic spread with recent outbreaks and deaths raising more concerns amidst the COVID-19 pandemic. As of now, there is no antiviral drugs or vaccine against MERS-CoV available. Here we provide a perspective on receptor usage, the risk of MERS-CoV and other CoVs evolution on future pandemics, and the mechanisms of MERS-CoV-derived nAbs. We offer insight into how these antibodies cross-react and cross-neutralise by analysing available structures of spike glycoprotein-antibody complexes. This review provides an update and a basis for the development of antibodies and vaccines for MERS-CoV, and possibly for the designing of next-generation pan-coronavirus vaccines and antivirals.}, }

Ovid MEDLINE and Embase were searched for studies published between December 2019 and May 2024. Observational studies examining adults with no history of type 2 diabetes comparing the development of insulin resistance and beta-cell dysfunction between COVID-19 exposed groups vs. controls were included. Risk of bias was assessed using adapted Newcastle-Ottawa and Joanna Briggs Institute scales. Among 6901 studies screened, 10 met the inclusion criteria. Across these studies, 37 individual measures of insulin resistance and beta-cell dysfunction were reported. Insulin resistance worsened significantly in 16 of 25 (64.0%) comparisons, whereas beta-cell dysfunction worsened significantly in 7 of 12 (58.3%) measures among COVID-19 patients when compared to controls. Five studies were considered low risk of bias. COVID-19 was associated with worsened insulin resistance and beta-cell dysfunction, suggesting infection may be a metabolic stressor that overwhelms gluco-regulatory mechanisms.

This shift necessitates a rigorous quantitative synthesis of how FWAs relate to critical employee and organizational outcomes. This study examines the associations between FWAs and work–life balance (WLB), work–family conflict (WFC), and organizational commitment (OC).<br><br>METHODS: A systematic review and meta&#x2013;analysis was conducted across five electronic databases. Initially, 3,777 records were identified. Following the application of strict inclusion and quality criteria, 38 studies from 19 countries (N&#x2009;=&#x2009;83,951) were selected for analysis. Data were synthesized using the Comprehensive Meta&#x2013;Analysis (CMA 3.0) software, employing a random&#x2013;effects model to calculate pooled effect sizes.<br><br>RESULTS: The findings revealed significant and relatively large positive correlations between FWAs and WLB (r = .39, p < .001) and between FWAs and OC (r = .29, p < .001).

During the COVID-19 pandemic, IMD incidence declined sharply across all age groups, including older adults. Post-pandemic data indicate a re-emergence of IMD among older populations, with incidence in several regions returning to or exceeding pre-pandemic levels by 2023. Across multiple locations, serogroup Y emerged as the dominant or increasingly prevalent serogroup among older adults. CFR varied by region and serogroup and consistently remained high in this age group.<br><br>CONCLUSION: These findings demonstrate the re-emergence of IMD among older adults and highlight the need for strengthened IMD surveillance and serogroup monitoring in this population, to guide prevention strategies and inform public health policy.}, }

Studies in the last few decades have highlighted that factors such as low education, high levels of unemployment, poor housing and reduced access to healthy food are strongly associated with the higher incidence of lifestyle risks-smoking, obesity and physical inactivity. These in turn increase rates of hypertension, dyslipidaemia and diabetes in the population. Beyond lifestyle factors, psychosocial mechanisms such as chronic stress and associated increase in allostatic load, due to long-standing deprivation, contribute to the biological risk of CVD. Early life disadvantage, ethnic and gender inequalities, and delayed management of intermediate risk factors further exacerbate the regional divide in England. Furthermore, the long-term impacts of COVID-19 and healthcare-associated national policies, including austerity-related funding deductions, have intensified pre-existing disparities. Evidence demonstrates that current preventative strategies, such as the National Health Service Health Check, have had limited success in reaching underserved communities, highlighting the need for targeted therapies. The National Institute of Health and Care Research Inequalities Challenge is a remarkable opportunity for the United Kingdom's (UK) leading research organisations to help tackle these inequalities associated with CVD and make a significant difference. Without such efforts, the excess CVD burden is likely to persist, perpetuating entrenched health inequalities. This review examines the different social determinants of health underlying these disparities, with a particular focus on socioeconomic deprivation, lifestyle risk factors, environmental and structural issues.}, }

Black and Hispanic patients remain significantly less likely than White patients to undergo outpatient TJA, even when controlling for clinical comorbidities. Recent data also suggests that residence in socioeconomically disadvantaged neighborhoods is associated with longer lengths of stay and higher early healthcare utilization. Furthermore, sex-based differences have emerged in postoperative pain management, with women demonstrating higher rates of opioid exposure and persistence. While younger, healthier, and privately insured patients have disproportionately benefited from outpatient pathways, those with public insurance or higher comorbidity burdens face persistent structural barriers to candidacy and safe discharge.<br><br>SUMMARY: Achieving equitable outpatient TJA requires a shift from exclusionary risk-screening to an equity-centered framework. This proposed model spans inclusive candidacy, optimization through prehabilitation, care navigation, and the use of site-of-service metrics. Ultimately, mitigating these disparities will require coordinated, multilevel action across policy reform, clinical practice innovation, and community engagement to ensure that the benefits of surgical innovation are accessible to all patient populations.}, }

These responses are accompanied by metabolic disturbances that generate distinct biochemical signatures measurable through advanced analytical platforms, such as mass spectrometry and nuclear magnetic resonance spectroscopy (NMR). Although numerous studies have examined these metabolic alterations, findings remain fragmented across clinical and analytical disciplines, leaving it unclear whether the systemic metabolic response to acute insult is fundamentally conserved or insult-specific. In this comparative review, we consolidate evidence across diverse injury and infection contexts to identify shared metabolic patterns, context-dependent differences, and critical gaps in current understanding. Here, we focus on lipid and lipoprotein profiling of blood plasma and serum. We present exemplar case studies spanning traumatic brain injury, burn injury, and SARS-CoV-2 infection to illustrate how lipid and lipoprotein perturbations differ or converge across insult types. Notable observations include consistently elevated palmitic acid (16:0) and reduced phosphatidylcholine species across all three conditions, suggesting these features may represent cross-condition biomarkers and highlighting the value of comparative metabolic profiling. By integrating evidence across diverse contexts, we propose a framework describing the interplay between lipid metabolism, lipoprotein dynamics, and inflammatory activation. Finally, we discuss the translational potential of metabolic phenotyping in enhancing patient stratification, refining prognostic modelling, and improving patient outcomes.}, }

This review encompasses studies published within the last five years with a focus on original research and systematic reviews that provide molecular, histological, or clinical evidence. The findings show that SARS-CoV-2 can infect ocular tissues through multiple receptors beyond angiotensin-converting enzyme 2 (ACE2), including transmembrane serine protease 2 (TMPRSS2), CD147, alanyl aminopeptidase N (ANPEP), dipeptidyl peptidase 4 (DPP4), angiotensin II receptor type 2 (AGTR2), and polymeric immunoglobulin receptor (PIGR), which are expressed in retinal, conjunctival, corneal, limbal, and photoreceptor cells. The virus may also reach ocular structures via neurovascular invasion. Clinically, patients with coronavirus disease 2019 (COVID-19) may present with a broad spectrum of ophthalmic manifestations, including conjunctivitis, hyperreflective lesions in the inner retinal layers, flame-shaped hemorrhages, cotton-wool spots, retinal pallor, hard exudates, and various forms of maculopathy, such as paracentral acute middle maculopathy and acute macular neuroretinopathy (AMN). These signs reflect both direct viral damage and secondary effects of systemic inflammation and microvascular injury. Understanding the molecular and clinical spectrum of ocular involvement is essential for early diagnosis, appropriate ophthalmologic care, and the prevention of long-term visual sequelae in patients affected by COVID-19.}, }

A database search in PubMed, PsycINFO, and CINAHL identified 357 unique peer-reviewed articles to screen and five were included in the review. Studies were included if they reported empirical data on cannabis use among caregivers for older adults. Of the five included studies, four studies found that caregivers reporting high stress or emotional burden used cannabis to cope, with two finding new or increased use during the COVID-19 pandemic. One study found that using cannabis improved caregivers' self-reported health and well-being; another found positive caregiver attitudes toward recreational cannabis. Two studies found higher caregiver anxiety was associated with increased cannabis use. Despite limited research, these studies underscore the role of cannabis as a potential coping mechanism for caregivers of older adults experiencing emotional burden. Additional research should seek to characterize longitudinal patterns of cannabis use among caregivers and its potential impact on both caregiver and care recipients.}, }

Millions of people have lost their lives due to the infection caused by this virus. The ability of the virus to spread rapidly and infect large numbers of people has highlighted the need to understand its mechanisms of infection. Angiotensin-converting enzyme 2 (ACE2) is an essential receptor for SARS-CoV-2 cell entry. SARS-CoV-2 exhibits a high affinity to this receptor and shows high infectivity, leading to an explosive increase in patients infected with COVID-19. ACE2 is the carboxypeptidase homolog of ACE, which produces angiotensin II, the main active peptide of the renin-angiotensin system. From a pathophysiological perspective, this system regulates vital processes across different organs. Additionally, ACE2 enzyme activity could play a protective role against acute respiratory distress syndrome (ARDS) caused by viral pneumonia. Upon infection, SARS-CoV-2 downregulates the expression of ACE2, which is possibly related to the pathogenesis of ARDS. Since this receptor is present in various other tissues such as the heart, kidney, gastrointestinal tract, reproductive system, and sensory organs, it may contribute to pathological symptoms in these organs. Thus, ACE2 is not only a receptor for SARS-CoV-2 but may also play a crucial role in various aspects of the pathogenesis of COVID-19 and potential post-COVID-19 syndromes. Administering ACE2 could competitively bind to SARS-CoV, thereby reducing viral spike protein from attaching to transmembrane ACE2 and consequently reducing viral cell entry into cells and COVID-19 symptoms. In this review, we first examine the role of ACE2 in the pathophysiology of SARS-CoV-2 across different tissues and propose treatment strategies for COVID-19 that involve ACE2.}, }

We begin with the genomic and structural characteristics of high-consequence zoonotic viruses, highlighting the molecular determinants for virulence, host switching, and immune evasion. The review then provides a comparative review of the emerging vaccine platforms such as mRNA, DNA, viral vector, subunit, and inactivated vaccines based on design rationale, delivery systems, immunogenicity profiles, and global rollouts. At the same time, molecular mechanisms of antiviral drugs acting against viral polymerases, proteases, and entry mechanisms are discussed, and the new challenge of resistance evolution is emphasized. We also highlight recently developed molecular diagnostic tools like CRISPR-based tools, nanopore sequencing, and isothermal amplification technologies that are transforming real-time pathogen diagnosis in veterinary and human medicine.

High rates of severe illness, hospitalizations, and long-term complications highlighted an urgent need for effective therapeutic agents. This necessity drove unprecedented efforts in drug discovery and repurposing. Remdesivir, developed by Gilead Sciences in 2009, was initially designed as a broad-spectrum antiviral targeting Ebola virus disease. Following observations of broad antiviral activity against coronaviruses, remdesivir was granted Emergency Use Authorization by the FDA in May 2020 for hospitalized patients with severe COVID-19. The FDA subsequently issued full approval in October 2020, expanding remdesivir's use to hospitalized adults and pediatric patients aged 12 years or older and weighing at least 40 kg.<br><br>AIM: This paper aims to assess the advantages and limitations of remdesivir in the treatment of COVID-19, drawing on evidence from clinical trials and examining its application in patients with congenital heart disease (CHD).<br><br>METHODS: The literature review was conducted until September 2025 using PubMed and Google Scholar searching for recent clinical trials in addition to relevant reviews.<br><br>RESULTS AND CONCLUSION: Remdesivir has been shown to shorten recovery time and lower mortality risk, particularly in patients at an early stage of infection with mild disease severity or requiring oxygen support. Although early guidelines advised against its use in patients with severe renal impairment, subsequent studies confirmed its safety prompting an FDA label update to allow use regardless of renal function. While some trials reported limited effects, the overall body of evidence supports remdesivir's role in improving clinical outcomes in COVID-19 treatment. In patients with CHD, the uncertain effects of both COVID-19 and remdesivir highlight a key research gap, emphasizing the need to refine existing therapies while following National Institutes of Health (NIH) treatment guidelines.}, }

Driven by worsening air pollution, tobacco use, occupational exposures, the COVID-19 pandemic, and population aging, they show persistently high incidence with rising mortality and disability, posing a major global public-health challenge. Current pharmacotherapies-principally antibiotics, glucocorticoids, β2-adrenoceptor agonists, and antiviral agents-yield only limited benefit and are constrained by adverse reactions such as gastrointestinal disturbances and hepatorenal toxicity, alongside the escalating problem of drug resistance. The development of safer and more effective therapeutics is therefore of considerable clinical and socioeconomic importance. Plant-derived natural products have attracted increasing interest in the management of respiratory diseases. Polydatin (resveratrol-3-O-β-D-glucoside; also known as piceid; PD) is a stilbenoid polyphenol of plant origin that is widely distributed in Polygonum cuspidatum (Japanese knotweed), Polygonum multiflorum, grapes, peanuts, mulberries, blueberries, and rhubarb. Accumulating evidence indicates that PD exerts anti-inflammatory, antioxidant, antimicrobial, immunomodulatory, and metabolic-regulatory activities and shows potential therapeutic value in pulmonary fibrosis, acute lung injury/acute respiratory distress syndrome, pneumonia, lung cancer, and asthma. This review provides a comprehensive synthesis of the multi-target and multi-pathway mechanisms by which PD acts against respiratory diseases, offering a mechanistic rationale and evidence base to support its clinical development.}, }

The hyper-activation of the immune response in COVID-19 patients is associated with disease progression and severity. As a result, immunomodulatory therapies such as colchicine have been suggested to control exaggerated immune response in COVID-19. However, the therapeutic role of colchicine in COVID-19 remains a subject of debate due to conflicting evidence. This review highlights both the beneficial and potentially harmful effects of colchicine in the context of COVID-19. Notably, the therapeutic advantages of colchicine are linked to the suppression of immune cell over-activation, attenuation of oxidative stress, and prevention of thrombo-inflammatory events. Conversely, colchicine may exert negative effects by disrupting microtubule function, impairing autophagic processes, and inducing mitochondrial dysfunction in COVID-19. In conclusion, the overall clinical impact of colchicine plays a critical role in the management of COVID-19.

The conceptualization of the lung-brain axis has advanced our understanding of the bidirectional communication between the respiratory and central nervous systems. Accumulating evidence indicates that pulmonary diseases, including chronic obstructive pulmonary disease, asthma, acute respiratory distress syndrome and infections such as bacterial pneumonia, influenza and Coronavirus Disease 2019, along with airborne environmental exposures, constitute significant risk factors for various neurological disorders. The lung-brain axis is primarily mediated by microbial, immune, neural, metabolic and hormonal pathways. These mechanisms contribute to the disruption of blood-brain barrier integrity, the activation of neuroglial cells and the dysfunction of the cerebrovascular system, ultimately causing neuronal injury and diverse neurological conditions. Environmental factors, notably airborne particulate matter and chemical pollutants, further amplify the crosstalk among these mechanisms, extending the neurological risk. Here, we summarize the current knowledge regarding the association between pulmonary dysfunction and the development and progression of neurodegenerative diseases (such as Alzheimer’s disease and Parkinson’s disease), stroke, anxiety/depression, epilepsy, and migraine. Additionally, potential therapeutic strategies targeting the lung–brain axis are discussed to foster further research in this emerging field. Elucidating the complex interactions within the lung–brain axis will not only deepen our understanding of the shared pathophysiological mechanisms but also open novel avenues for the early diagnosis, prevention, and treatment of related neurological diseases.}, }

Reference lists and trial registries were screened for additional and ongoing studies.<br><br>METHODS: Following the JBI convergent integrated approach and PRISMA 2020 guidelines, quantitative data from randomized controlled trials (RCTs) were pooled in random-effects meta-analyses for family satisfaction and patient anxiety. Numerical findings from non-RCTs were qualitized and synthesized narratively. The qualitative data were subjected to thematic synthesis. All results were integrated into a single line of argument.<br><br>RESULTS: Fifty-four studies were included, comprising 22 qualitative, 25 quantitative, and 7 mixed-methods designs from 19 countries; 92% were conducted during the COVID-19 pandemic. Over half of the studies examined virtual visiting or video communication (57%, n&#x2009;=&#x2009;31), whereas the others evaluated structured patient-status updates, family support teams, dynamic interaction platforms, or interventions for mechanically ventilated or delirious patients. Methodological quality was moderate to high in 96% of the studies. The meta-analysis of three RCTs demonstrated a moderate to strong improvement in family satisfaction (standardized mean difference&#x2009;=&#x2009;0.76, 95% CI 0.45&#x2013;1.06, p&#x2009;<&#x2009;.001) with virtual communication compared with usual care. Pooled effects on patient anxiety (mean difference = -2.19, 95% CI -4.62 to 0.23) and depression were nonsignificant, although qualitative findings consistently described perceived reductions in anxiety, loneliness, and emotional distress. Across study types, digital communication enhanced information sharing, supported shared decision-making, and increased family involvement. Key barriers included technical difficulties, privacy concerns, and staff workload, whereas facilitators comprised user-friendly technology, structured preparation, and continuity through a dedicated contact person.<br><br>CONCLUSIONS: Digital communication in adult ICUs is feasible, acceptable, and beneficial for patients, relatives, and healthcare professionals. Virtual tools improve family satisfaction and complement patient- and family-centred care, but sustainable integration requires clear protocols, staff training, and ethical frameworks beyond pandemic conditions.<br><br>SUPPLEMENTARY INFORMATION: The online version contains supplementary material available at 10.1186/s13054-025-05826-5.}, }

However, HFNC failure can lead to adverse outcomes, including increased mortality. This narrative review examines predictive factors and indices for HFNC failure, including respiratory rate, P/F and S/F ratios, the ROX index, HACOR score, and emerging indices, such as VOX and FOX. Among these, the ROX index and HACOR score currently provide the most robust predictive value, whereas newer tools such as VOX and FOX require further validation. The ROX index, combining oxygenation and respiratory rate, has shown significant predictive value, particularly in COVID-19 patients, though its thresholds and timing for assessment remain variable. Modified versions of the ROX index, incorporating heart rate and PaO2, have improved predictive accuracy. The HACOR score, initially developed for non-invasive ventilation, also predicts HFNC failure but may be less discriminative in emergency settings. Emerging indices such as VOX and FOX offer novel approaches but face clinical application challenges due to measurement complexities. Risk stratification models, scoring systems, ultrasound techniques, and machine learning methods show promise but require further validation. This review highlights the importance of integrating multiple predictive tools and tailoring assessments to individual patient conditions. Future strategies must also account for nursing quality variables to enhance prediction accuracy in real-world settings. Comprehensive training for healthcare professionals and future multicenter, large-scale studies is essential to refine these predictive strategies and improve patient care quality.}, }

Vaccination against the pandemic was considered as an effective tool for the prevention and containment of the virus. Following the outbreak of the Coronavirus pandemic, efforts were made to enhance procurement and distribution of vaccines across countries with the view to containing the pandemic. However, evidence suggested that several factors hindered access, acceptance and use of the COVID-19 vaccines across the globe. This scoping review, thus, explored factors that influenced access, acceptance and use of the COVID-19 vaccines among Ghanaians and strategies that were needed to improve vaccine uptake especially for the vulnerable populations.<br><br>METHODS: We adopted the five-stage analytic framework developed by Arksey and O'Malley to map existing literature on what has been done and documented on the subject.

Health system factors including untimely payment of vaccinators allowances, shortfalls in logistics and vaccines, lack of transport and long queues at vaccination centers affected access and uptake of the COVID-19 vaccines in Ghana. Additionally, beliefs and perceptions including myths, misconceptions and misinformation around the virus and the vaccines affected people's decision-making to participate in the vaccination exercise. Also, negative reportage through social media platforms created mistrust in COVID-19 vaccine intensions.<br><br>CONCLUSION: Even though Ghana made significant progress in addressing the Coronavirus pandemic, hesitancy factors played a crucial role in diminishing Ghana's effort towards meeting global targets in containing the virus and reducing its impact. Strengthening Ghana's public health preparedness and response strategy, through a community-based approach and multi-stakeholder engagement, could improve immunization programs and vaccines uptake in addressing future pandemics.}, }

It exists primarily as ergocalciferol (vitamin D2) and cholecalciferol (vitamin D3), which are biologically inactive until undergoing a sequential hydroxylation in the liver to form 25-hydroxyvitamin D (calcidiol), and subsequently in kidney to form the active metabolite 1,25-dihydroxyvitamin D (calcitriol). By engaging the vitamin D receptor, it exerts immunomodulatory, neuroprotective, and anti-frailty functions. Deficiency in vitamin D has been implicated in a wide range of disorders, including musculoskeletal weakness, frailty, cognitive decline, autoimmune diseases, and respiratory infections. Vitamin D deficiency affects nearly half of the global population and remains a widespread public health challenge, and effective interventions such as food fortification and targeted supplementation should be prioritized in future strategies.<br><br>Vitamin D deficiency represents a modifiable risk factor with implicated effects across systemic, neurocognitive and musculoskeletal systems. Epidemiological evidence links deficiency to increased risk of infection, cognitive decline, frailty and orthopaedic morbidity. In orthopaedic and geriatric populations, maintaining sufficient vitamin D supplementation may reduce fracture and fall risk as well as postoperative complications and infections. These factors are also influenced by vitamin D deficiency-related effects on neurocognition. Vitamin D status may also be relevant in the management of infectious diseases, including respiratory illnesses and COVID-19. This review also discusses mechanistic and practical rationales for clinical translation. Potential interventions include vitamin D co-supplementation, dietary fortification and optimised sun exposure. However, limitations in existing randomised trials underscore the need for consistency in dosing, appropriate formulation, targeted population, as well as baseline deficiency progression status. These insights can guide clinicians, public health policy makers and researchers in developing evidence-based protocols and interventions to reduce vitamin D deficiency-related morbidity.}, }

Therefore, there is a major opportunity in a comprehensive lifelong risk management, which includes individual risk stratification and holistic preventive measures. Definite possibilities for improvement are provided by, e.g., targeted statutory measures for reduction of nicotine consumption and early check-ups in young adulthood (25, 35 and 50 years) for detection of hypertension and other risk factors, screening for familial hypercholesterolemia in children and promotion of vaccination against influenza, pneumococci, severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) and respiratory syncytial virus (RSV), especially for people with heart disease.

The intricate nature of their mechanisms and the impact of the underlying condition make it challenging for clinicians to anticipate the infectious risks and vaccination outcomes for individuals prescribed these therapies. We aimed to summarise the current evidence focusing on the risk of infections, vaccine efficacy and vaccine safety in patients receiving targeted therapies. Our review revealed variable infection risks and vaccine responses in patients on targeted therapies, ranging from dramatic (e.g., alemtuzumab, rituximab) to negligible (e.g., mepolizumab, imatinib). Higher risks of serious infection were associated with receipt of concomitant immunosuppressive medications. Vaccine immunogenicity data were predominantly restricted to COVID-19, influenza, and pneumococcal vaccines, with fewer studies on herpes zoster and hepatitis B vaccines. Vaccine responses were often impaired by many targeted therapies, but rarely eliminated. Therapies with lymphocyte-depleting effects, however, can result in inadequate vaccine responses, and were often affected by underlying conditions and concomitant immunosuppressants. Live vaccine safety remains a prominent concern for patients prescribed targeted therapies, though serious adverse events are rare. Current evidence is largely based on non-randomised trials and observational studies, which limits the strength of conclusions that can be drawn. To address this gap and ensure accurate evaluation of vaccine immunogenicity, clinical efficacy and safety, it is essential that future trials include immunocompromised individuals. Better prediction models or biomarkers for stratifying risk and predicting vaccine efficacy are also important further steps.}, }

Evolving viruses with improved fitness are subject to positive selection and will pass on their genetic information to the next generation. If virus populations experience similar environmental pressure, they may undergo a dynamic process of molecular adaptation, which is known as convergent or parallel evolution (parallelism). Noteworthy, these phenomena are among the underlying mechanisms of cross-species transmission and emergence of novel viruses in the human population with a significant impact on global health. Therefore, it is essential to comprehend the fundamental concept of parallelism as well as its molecular identification. This will contribute to a better preparedness against future viral epidemics and pandemics. In this review, we first describe the basic concept of parallelisms and various selective pressures that drive this process. We highlight viruses that commonly infect humans, including hepatitis C virus (HCV), human immunodeficiency virus (HIV), and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), as examples of rapidly evolving viruses undergoing this evolutionary process.

Recent viral outbreaks such as COVID-19, Human metapneumovirus (HMPV), Zika, Ebola, Nipah, and various influenza viral strains have highlighted the limitations of conventional antivirals. This necessitates the need for targeted, adaptable, and innovative drug delivery platforms. In light of this, LNCs have emerged as versatile systems capable of enhancing drug stability, biodistribution, and cellular uptake.

Despite notable progress, challenges in scalability, stability, and regulatory compliance limit their clinical translation. Hence, techniques such as microfluidics and other continuous manufacturing approaches improve reproducibility and process control. Moreover, artificial intelligence is revolutionizing LNC development by enabling rapid optimization, in silico prediction of pharmacokinetics, and real-time quality monitoring. Incorporating AI-enabled quality-by-design frameworks with state-of-the-art analytics may streamline regulatory approval.

Proteolytic processing of polyproteins is an indispensable regulatory step for virus maturation and replication that is carried out by the virus-encoded and/or cellular proteases. The activity of a viral protease that is expressed as a part of a polyprotein is controlled in part by the self-cleavage (autoprocessing) from the precursor. The mechanism of protease precursor processing has been established at the molecular level for various RNA virus proteases, including human immunodeficiency virus (HIV) and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Both viral protease precursors are processed via intra- (in cis) and intermolecular (in trans) cleavages at the N- and C-termini, respectively, yielding the mature enzyme. The remarkably similar activation mechanisms of HIV and SARS-CoV-2 PRs suggest that other viral proteases are activated similarly. In this review, we provide a detailed overview on the protease precursor autoprocessing mechanism of HIV-1 and SARS-CoV-2 proteases and compare those to the activation mechanism of non-viral proteases from their zymogens. Also, we review the activation mechanism of other ss(+)RNA viruses that utilize the polyprotein pathway for their replication. Based on such comparison, it appears that the protease activation mechanisms of most enveloped ss(+)RNA viruses from their precursors share many common features, although they do not correlate directly with the evolutionary relationships, the presence or absence of viral envelope or the catalytic mechanism of the viral protease.}, }

Following JBI scoping review methodology and PRISMA-ScR guidelines, seven electronic databases will be searched for literature published between January 2022 and 2025. Empirical studies examining educational adaptations and practice-embedded interprofessional strategies implemented during COVID-19 will be included. Two independent reviewers will conduct screening and data extraction, with findings synthesized narratively. IPECP and VUCA frameworks provide an analytical lens for examining identifying of educational and practice adaptations associated with coordinated healthcare responses. Findings are intended to enforce workforce resilience and future preparedness efforts. This protocol has been registered on OSF doi: https://doi.org/10.17605/OSF.IO/A6F3D.}, }

Six studies met the inclusion criteria, and focused on the factors of COVID-19 vaccine acceptance, hesitancy, and access in the DRC.<br><br>RESULTS: Although surveys indicated a high willingness on the part of the people to get vaccinated, only 2.7% of the population were fully vaccinated. The primary barrier to vaccination was safety concerns, specifically, perceptions of the vaccine as new and experimental (84.4%) and fear of side effects (83.3%). Additional hesitancy factors included mistrust in vaccine effectiveness (60.4%) and a general lack of confidence (60.0%). Facilitators of acceptance included prior family vaccination, perceived risk of infection, belief in the existence of the virus, and awareness of vaccination strategies. Sociodemographic factors such as being a healthcare professional or male also positively influenced uptake.<br><br>DISCUSSION: These findings highlight the gap between vaccine willingness and actual coverage in the DRC. Addressing safety concerns and building trust through targeted outreach, especially among key professional groups, may improve vaccine acceptance and equity.}, }

A comprehensive search was conducted in three databases (PubMed, Web of Science, and Scopus) up to January 2025 (included). Studies were included based on PICO criteria, involving adult athletes, original articles, and any quantitative assessment of physical fitness and/or body composition conducted within one month before and two weeks after the lockdown. The Joanna Briggs Institute Critical Appraisal Checklist was used to assess the risk of bias, while the Cochrane Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach evaluated the certainty of evidence. A total of 14 studies (261 athletes) with a low risk of bias met the inclusion criteria. Narrative synthesis revealed that the effects of lockdowns on athletes' physical fitness and body composition were varied, with consistent impairments (e.g., endurance-related fitness), relative stability (e.g., body mass, CMJ height, maximal strength), and mixed results (e.g., sprinting). A meta-analysis of 11 studies indicated a non-significant effect of lockdown on body mass (effect size [ES]=-0.115, 95% confidence interval [CI] -0.214 to 0.164, P=0.797). Similarly, 10 studies showed a variable, non-significant reduction in CMJ height (ES=-0.303, 95% CI -0.655 to 0.045, P=0.097). However, CMJ relative peak power (six studies) demonstrated a trivial-small negative effect (ES=-0.199, 95% CI -0.341 to -0.058, P=0.019). These findings should be interpreted with caution as the certainty of evidence was very low. While evidence remains limited, targeted and individualised training might help mitigate some of the detraining effects observed during a lockdown, particularly in endurance-related fitness outcomes.}, }

Technology-driven interventions, including digital therapeutics, web-based programs, and mobile applications, have expanded treatment access. The COVID-19 pandemic accelerated the adoption of digital approaches, and national policy calls for enhanced use of telehealth and app-based recovery support. However, user engagement with SUD apps remains a challenge.<br><br>OBJECTIVE: This narrative review summarizes evidence on digital interventions for SUDs, emphasizing mobile apps. It examines what differentiates effective interventions, drawing on insights from the broader context of general mobile app use. It also proposes strategies to enhance engagement in digital therapeutics.<br><br>METHODS: We reviewed the literature (2013-2025) on SUD digital interventions, including randomized trials, systematic reviews, and large observational studies of SUD-focused apps. Key findings on clinical efficacy and engagement were extracted, along with examining engagement tactics from mobile gaming and other app domains to inform potential improvements.<br><br>RESULTS: Several apps have demonstrated efficacy in reducing substance use or supporting abstinence, particularly those that integrate evidence-based therapy content, provide personalized feedback, offer craving-management tools, and facilitate connectivity to peer or clinician support. In contrast, apps with minimal interactive content often show no added benefit. A major barrier is sustaining user engagement, as many SUD apps experience a steep drop-off in use after the initial download. Strategies such as gamification, contingency management (utilizing incentives), social networking features, and integration with ongoing care can significantly enhance engagement. Early data suggest that blending these strategies into SUD apps yields higher retention and better clinical results.<br><br>CONCLUSION: Mobile apps are emerging as valuable adjuncts for SUD treatment, but their real-world impact depends on users' engagement with compelling content. By incorporating tangible rewards, personalized and timely interventions, social support, and provider involvement, digital therapies for SUDs enhance engagement and, consequently, improve long-term recovery outcomes.}, }

Recent studies have underscored the pivotal role of TLR7 in shaping immune responses to respiratory viral infections, including SARS-CoV-2, influenza A virus, and respiratory syncytial virus (RSV), as well as in the pathogenesis of systemic autoimmune diseases such as systemic lupus erythematosus (SLE), which can be triggered by the respiratory viral infections. In COVID-19, TLR7 deficiency is associated with severe disease, particularly in males, due to impaired interferon responses and antibody production. In influenza, TLR7 enhances humoral and cytotoxic responses, though its overactivation may contribute to immunopathology. The role of TLR7 in RSV remains controversial, with both protective and detrimental effects reported depending on host and experimental context. In contrast, TLR7 plays a pathogenic role in SLE by amplifying type I interferon signaling and promoting autoreactive B cell activation. This review synthesizes current knowledge on TLR7-mediated signaling across these diseases, highlighting its context-dependent functions and dualistic nature in immunity and disease. We will discuss mechanistic insights, clinical relevance, and emerging therapeutic strategies targeting TLR7, emphasizing the need for precision modulation of this pathway in the treatment of viral infections and autoimmune disorders.}, }

Global comparative data remain limited.<br><br>METHODS: Following PRISMA guidelines (CRD42023481670), a systematic review and meta-analysis was conducted. Cases were categorized into seven subtypes to assess variation across regions.<br><br>RESULTS: 2,031 studies (40,860 cases, 77 countries) were included. Non-invasive forms accounted for 60% (n=24,582) of cases, mainly fungal ball (35%, n=14,280) and allergic FRS (25%, n=10,302). Invasive subtypes were more frequent in tropical climates, with the hyperacute rhino-orbito-cerebral mucormycosis predominating. This subtype differed from acute and subacute invasive FRS in risk factors (diabetes and COVID-19 vs. leukemia) and geography. Aspergillus species appeared in ~60% of cases: A. fumigatus dominated in temperate/continental zones, while A. flavus was frequent in dry/tropical regions.

First-generation modalities, demonstrated by fomivirsen and pegaptanib were limited by vulnerability to nuclease attack, inefficient delivery and immune stimulation were treated with clinical feasibility. Recent clinical achievements, including mRNA vaccinations against COVID-19, have been based on developments in backbone chemistry, nucleoside modifications and targeted delivery including N-acetylgalactosamine (GalNAc) conjugation and lipid nanoparticle (LNP) encapsulation. On this basis, it can be stated that the RNA Therapeutics 2.0 is more stable, tunable and can be targeted to organs and tissues. New methodologies such as circular RNA (circRNAs), self-amplifying mRNAs (saRNAs), splice-switching adenosine specific oligonucleotides (ASOs), small-molecule splicing modulators and adenosine deaminase toward RNA (ADAR)-directed base editors. These new generation systems can be used to make durable protein expression, reversible transcript recoding and precision splicing modulation, extending therapeutic applications to oncology, neurology, metabolic disease and rare genetic disorders. Extrahepatic delivery via innovations in delivery that included ligand-targeted LNPs, peptide conjugates and engineered exosomes is surpassing and artificial intelligence (AI) enhanced design is hastening optimization of RNA sequences, chemistries and vectors.

Vaccine-preventable infections pose significant risks, including increased morbidity and mortality, reduced quality of life, and substantial healthcare costs. Prevention, particularly adult vaccination, plays a vital role in mitigating these outcomes and supporting healthy ageing. While childhood immunization remains essential, a life-course approach including routine older adult vaccination is needed. Coverage among older adults across Europe remains suboptimal owing to factors such as heterogeneous (sub)national policies, health literacy issues, financial barriers, access issues, and persistent structural and societal barriers. To meet these challenges, the Adult Immunization Board (AIB) convened a technical meeting in May 2025, to discuss strategies for improving vaccination in older adults. The meeting explored how older adults are defined in immunization policies (for the meeting, an operational threshold of ≥ 50 years was used, while acknowledging that many national age-based programs commonly start around 60-65 years) and reviewed current adult vaccines and programmatic implementation across six vaccines. Discussions highlighted the need for a life-course approach with coordinated (inter)national policies, clear adult vaccination schedules, dedicated infrastructure and programs, stronger surveillance, and structured follow-up. Key recommendations included shifting from fragmented efforts to cohesive, system-wide approaches. This approach requires addressing organizational challenges with programmatic strategies such as integrating adult vaccination into routine healthcare, providing co-administration guidance, and adapting successful pediatric models for adult programs. This summary presents insights shared during the AIB meeting, highlighting gaps and promising solutions for advancing older adult immunization in Europe. Vaccination must be recognized as an investment in healthy ageing, which is also able to generate a return in economic terms, as part of a holistic health package for older adults, not as an optional add-on to treatment. With older adults now outnumbering children under 5 years globally, it is time to invest equally in their vaccination.}, }

This study assessed how trial size impacts effect estimates, statistical stability, and risk of bias. Following PRISMA guidelines, we identified meta-analyses of COVID-19 treatments included in WHO, NIH, and the LIVING Project. Trials were classified by log-scale sample size, and separate pooled meta-analyses were conducted for large-only, small-only, and combined trials. Comparative metrics included the Ratio of Odds Ratios (ROR), Kappa statistics, Fragility Index (FI), Reverse Fragility Index (RFI), and Cochrane Risk of Bias assessments. Sensitivity analyses applied alternative size thresholds (≥ 1000 participants and median-based cutoffs) and stratified results by treatment and outcome type. Across 25 meta-analyses including 221 RCTs (46 large, 175 small), small trials produced more extreme estimates in 19 analyses and wider confidence intervals in 23. The pooled ROR was 0.85 (95% CI: 0.76-0.95; P = 0.004), decreasing to 0.81 (95% CI: 0.68-0.95; P = 0.011) when limited to small trials published before the first large trial. RORs remained below 1 across treatment and outcome types. Agreement between small and large trials was minimal, while large trials showed substantial agreement with overall estimates. Stability and bias profiles favoured large trials (FI: 14.0 vs. 4.0; RFI: 10.0 vs. 5.0). In conclusion, small RCTs tend to overestimate treatment effects and yield less precise, less stable results. Meta-analyses should prioritise large, high-quality trials and interpret small-study findings with caution, particularly in rapidly evolving research contexts.}, }

We performed a critical narrative review integrating immunological mechanisms, available clinical data, and multidisciplinary expert opinion to inform vaccination strategies for patients with solid tumours treated with BsAbs. BsAbs can induce transient or sustained immune perturbations, including T-cell hyperactivation, lymphocyte redistribution, functional exhaustion, cytokine-mediated immune dysregulation, and, in selected contexts, B-cell impairment. These effects may reduce vaccine-induced humoral and cellular responses and increase vulnerability to infectious complications. Optimization of vaccination status before BsAb initiation is therefore advisable, as pre-treatment immunisation is more likely to achieve effective immune priming. Inactivated vaccines, including influenza, pneumococcal, SARS-CoV-2, hepatitis B (HBV), and recombinant herpes zoster vaccines, can be administered before or, when necessary, during therapy, whereas live attenuated vaccines should be avoided during active treatment. Vaccination timing during BsAb therapy should be individualised, taking into account the treatment schedule and immune recovery. Current recommendations rely largely on indirect evidence from haematological malignancies and other T-cell redirecting therapies. These considerations are essential to support treatment continuity, reduce preventable morbidity, and guide future prospective studies in patients with solid tumors treated with BsAbs.}, }

In this narrative review, we synthesize randomized controlled trials (RCTs), systematic reviews/meta-analyses, and recent guideline and regulatory updates on FMT in UC, and integrate mechanistic insights from microbiome and metabolomics research. Across RCTs, intensive lower-gastrointestinal regimens using pooled, multidonor material, and/or anaerobic processing have most consistently achieved modestly higher steroid-free clinical and endoscopic remission than placebo in mild-to-moderate UC (approximately 25%-32% vs 5%-10% in representative studies), whereas upper-gastrointestinal delivery or oral lyophilized formulations and highly restrictive donor selection have yielded mixed or negative results. Mechanistically, responders commonly demonstrate engraftment of short-chain fatty acid producing taxa and restoration of secondary bile acid pathways. Safety profiles in trials are generally comparable to placebo for common mild adverse events, but rare severe transmissions (e.g., multidrug-resistant Escherichia coli and SARS-CoV-2) have driven stricter donor screening and have limited routine use outside regulated programs. Current guidelines recommend against FMT for UC outside clinical trials. Future work should prioritize standardized protocols, biomarker-guided personalization, combination strategies (diet/priming), and development of defined microbial therapeutics to improve efficacy and safety.}, }

In low-resource countries, inadequate, if not absent, waste management systems lead to unsafe disposal practices, including open burning. While theory-informed approaches are essential for identifying enablers and barriers to target behavior change, their application is limited in these settings. Given the lack of a theory-driven synthesis of behavioral strategies to address plastic waste, this systematic review aimed to: (1) synthesize behavioral interventions related to plastic waste management in low-resource countries; (2) map these interventions to the behavior change wheel (BCW), using the capability-opportunity-motivation-behavior model, and the theoretical domains framework (TDF); and (3) classify implementation strategies to inform theory-driven intervention design. This review is the first to use the BCW to examine behavioral interventions related to plastic waste management in low-resource countries. Nine bibliographic databases: APA PsycInfo, CINAHL, Embase, Environment Complete, Global Health, GreenFile, Health Source: Nursing Academic, PubMed, and Web of Science Core Collection were searched. We included English-language human studies up to 9 April 2025, that evaluated interventions or policies targeting individual- or community-level behaviors related to plastic waste management in low-, lower-middle, or upper-middle income countries. We excluded studies from high-income countries, and those focused on environmental impacts, industrial or municipal waste streams, ecosystems or animals without human behavioral components, COVID-19-specific waste, or hypothetical modeling without real-life interventions. Forty-three studies met the inclusion criteria. Study quality was assessed using the mixed methods appraisal Tool. Interventions spanned 27 low-resource countries and targeted diverse populations, including schoolchildren, households, market vendors, and community organizations. Education was the most frequent BCW intervention function (76.7%), followed by environmental restructuring, incentivization, persuasion, and training. Mapping revealed that behavioral interventions relied most frequently on the TDF domains of environmental context, knowledge, skills, and social influences. Some domains, such as beliefs about capabilities, reinforcement, and identity, received moderate attention, while appealing to emotion or the use of behavioral regulation, were underutilized. Behavioral interventions for plastic waste management in low-resource countries have predominantly emphasized awareness-raising but insufficiently leveraged other BCW intervention functions and TDF domains. Integration of motivational, emotional, and identity-based strategies alongside structural support can enhance the sustainability of behavior change.}, }

Tele-neurology has emerged as a promising strategy to mitigate these barriers, particularly in the wake of the COVID-19 pandemic, which resulted in rapid digital health adoption. This review article examines the development and implementation of tele-neurology initiatives across Latin America, with a focus on Ecuador; drawing on examples such as TeleEEG, telestroke networks, and Project ECHO, I illustrate how digital tools have expanded the reach of neurological services in underserved regions. Despite demonstrable benefits, challenges persist, including uneven digital infrastructure, regulatory gaps, and disparities in access. I argue that tele-neurology must be deliberately integrated into national public health strategies, not merely as a pandemic contingency but as a potential long-term solution for health equity, if done properly. Strategic investments in broadband access, clinician training, sustainable financing, and regional collaboration are essential to scale these innovations. When anchored in strong policy frameworks and aligned with global neurological health goals, tele-neurology could offer a path toward closing the treatment gap and advancing equitable neurological care throughout Latin America.}, }

It is now recognized as a global mental health concern, more prevalent in urban settings and frequently comorbid with psychiatric disorders. In the post - COVID - 19 era, home - centered lifestyles have become increasingly normative, prompting a reconceptualization of hikikomori beyond reduced outing frequency. Drawing on over two decades of clinical and research experience, we propose a psychodynamic (developmental and attachment-informed), transdiagnostic, and multidimensional framework and outline assessment and intervention strategies for urban digital societies.<br><br>RECENT FINDINGS: International frameworks distinguish pathological from non-pathological hikikomori based on psychological distress and functional impairment. Emerging evidence implicates attachment insecurity, early adversity, and transdiagnostic biological pathways involving inflammation, and neurodevelopmental mechanisms. Early-phase pathological hikikomori is associated with increased risk of depression and gaming disorder, with possible relevance of modern-type depression. Digital tools, including online engagement and virtual reality based interventions, may provide low-threshold gateways to reach otherwise hard-to-reach individuals.<br><br>SUMMARY: In contemporary urban life, physical isolation per se is not necessarily pathological. Translating a biopsychosocial-cultural model integrating psychopathology and attachment into structured assessment, family-based approaches, clinical care, and digital interventions is essential to prevent long-term pathological hikikomori.}, }

This article examines the development and operational framework of BQC19, highlighting five key themes central to its success. First, BQC19's anticipatory governance model emphasizes adaptability, leveraging strategic foresight to maintain ethical and efficient operations during the pandemic. Second, the initiative's harmonized yet flexible consent processes ensured participant autonomy and compliance with evolving clinical and public health contexts. Third, BQC19's collaborative governance framework facilitated seamless interinstitutional cooperation, supported by standardized operating procedures and localized manuals of procedures. Fourth, streamlined data access mechanisms, managed by an independent data access committee, promoted ethical and equitable data sharing, balancing privacy considerations with research accessibility. Last, BQC19 demonstrates the transferability of its infrastructure to other health challenges, providing a scalable, ethical, and collaborative model for future public health crises. Through centralized data management, preestablished legal agreements, and tiered access protocols, BQC19 has significantly reduced response times and operational inefficiencies. Its achievements showcase the potential of biobanks in fostering global health collaboration, enabling rapid research mobilization, and addressing emerging health threats. BQC19's legacy lies in its ability to integrate innovation, ethics, and collaboration into a sustainable framework for public health preparedness.}, }

Despite ongoing research, no definitive cure has been identified. Preventive measures, including vaccines and monoclonal antibody-based interventions, have been developed to protect vulnerable populations, and hundreds of therapeutic candidates have been evaluated worldwide. Complementing these strategies, vitamin D and zinc (Zn) supplementation have emerged as promising, accessible adjunctive strategies due to their immunomodulatory and anti-inflammatory properties. This review synthesizes current experimental, clinical, and epidemiological evidence on the roles of vitamin D and Zn in modulating immune responses relevant to SARS-CoV-2 infection. Available data suggest that adequate vitamin D and Zn status may support immune function, reduce excessive inflammation, and potentially mitigate disease severity, particularly in deficient individuals. However, clinical trial outcomes remain heterogeneous. Overall, vitamin D and Zn supplementation may be considered supportive, adjunctive preventive measures.

This review focuses on co-delivered adjuvant drugs and introduces the concept of "mRNA translation boosters" for the first time. mRNA translation boosters are classified as small-molecule compounds and macromolecular agents that improve translational fidelity through mechanisms including blockade of pattern recognition receptors, modulation of inflammatory cascades, facilitation of endosomal escape, and protection against enzymatic degradation. As clinically validated with COVID-19 mRNA vaccines, these boosters have now demonstrated expanded utility in gene editing therapies and protein replacement applications.

Overall, studies most commonly reported that the COVID-19 pandemic had a negative or neutral effect on attitudes, intentions, and actions regarding vaccine acceptance.<br><br>CONCLUSION: This systematic review illustrates how the COVID-19 pandemic influenced vaccine acceptance and decision-making in complex, context-dependent ways, impacting people's thinking and feeling, motivations, practical issues, and social processes around vaccination. The findings highlight the need to understand the specific drivers of vaccine acceptance to design more effective, targeted strategies to improve immunization uptake. The insights from this study can be used to inform evidence-based vaccination catch-up strategies to regain pandemic losses and mitigate factors that deter individuals from seeking vaccination.}, }

This review addresses this gap by critically examining recent advancements and highlighting nanovaccine technologies that have undergone human clinical trials. Using an extensive search on clinicaltrials.org, we explored the diverse applications of nanovaccines, including leading SARS-CoV-2 candidates and platforms targeting other infectious diseases and cancers. We also highlighted foundational research that has enabled clinical investigation of nanovaccines over the past decade, highlighting their potential to address a range of medical conditions. While many technologies have been developed to combat SARS-CoV-2, several key innovations targeted a broader spectrum of diseases. This review details these technologies, focusing on their materials and mechanisms of action in inducing immune protection, while also exploring how nanomedicine facilitates nanovaccine development and introduces novel adjuvant concepts. Finally, we provided a retrospective analysis of the development journey of these platforms, offering insights into the intellectual and technological efforts behind their clinical translation.

This lack of harmonisation made it difficult to compare findings across studies, slowing evidence synthesis, and limiting the usefulness of data for modelling efforts and policy guidance. Drawing on our team's experience synthesising and modelling vaccine immunogenicity data during the pandemic, we discuss the long-term challenges of standardising human immunology research that were highlighted by the COVID-19 pandemic. We argue that vaccine immunogenicity studies require standardised reporting and quality assessment tools. We propose practical solutions to support comparability of laboratory-based practices, while preserving methodological diversity.

Because of these issues, researchers are exploring new approaches using nanotechnology. Quantum dots (QDs) and carbon dots (CDs) are two types of fluorescent nanodots with special optical and surface properties, becoming promising tools for detecting viruses. However, their different physical and chemical characteristics, biocompatibility, and integration potential lead to distinct analytical performances, highlighting the need for a comparative assessment of their applicability in viral biosensing.<br><br>RESULTS: This review systematically analyses recent advances in QD- and CD-based biosensors for viral detection, covering both nucleic acid- and protein-based assays. QDs show advanced techniques, with integration into fluorescence, FRET, ECL, PEC, and lateral-flow formats, enabling multiplexed detection of several viruses, including dengue, HAV, HBV, and SARS-CoV-2. In contrast, CDs are mainly used for single-target fluorescence or electrochemical assays, indicating they are in an earlier stage of development. Comparative studies reveal that QDs-based viral assays can detect targets such as HIV-1 nucleic acids at levels as low as 6.5&#xa0;&#xd7;&#xa0;10[-16]&#xa0;M, which is generally one order of magnitude lower than CDs, though the latter show better biocompatibility and stability. QDs offer a wider range of sensitivity and performance, while CDs provide safer, simpler, and more sustainable sensing options. These differing features define their unique analytical roles and potential for practical use.<br><br>SIGNIFICANCE: By bringing together findings from recent literature studies, this review bridges fundamental nanochemistry with practical virus diagnostics. It explains how QDs and CDs contribute differently to sensitivity, multiplexing, and biosensor integration, providing guidance for selecting suitable nanomaterials in analytical design.

Vaccines have been the most effective strategy for preventing severe illness and death in patients who acquire the infection. Vaccines induce both humoral and cell-mediated immune responses; the latter is crucial in the immune response against SARS-CoV-2, as the effector mechanisms of T-cells are less affected by the high mutation rate of the virus and prevail through memory phenotypes, ensuring long-term protection. mRNA vaccines have been primarily used worldwide to control the COVID-19 pandemic. This platform can protect against different circulating variants and is characterized by generating a robust T-cell response. This review discusses the immune response of T-cells induced by mRNA vaccines against SARS-CoV-2.

Integrated clinical, neuropathological, neuroimaging, and molecular evidence indicates that SARS-CoV-2-associated neurological injury is driven predominantly by receptor-mediated immune and vascular mechanisms rather than widespread productive central nervous system infection. Angiotensin-converting enzyme 2 (ACE2) remains the principal viral entry receptor, while neuropilin-1 (NRP1) facilitates neurovascular and olfactory access in specific contexts. In contrast, CD147 and dipeptidyl peptidase-4 (DPP4) appear to exert indirect modulatory roles through endothelial dysfunction and immune activation rather than acting as dominant neurotropic entry receptors. Toll-like receptors, particularly TLR2, TLR4, and TLR7, amplify neuroinflammatory signaling and contribute to blood-brain barrier disruption, microvascular injury, and sustained microglial activation. Cerebrospinal fluid biomarkers and neuroimaging findings consistently support a dual-pathway model combining limited direct viral presence with predominant immune-mediated injury. Current therapeutic strategies targeting receptor-mediated entry and neuroinflammation remain largely investigational, underscoring the need for biomarker-guided and phase-specific interventions. These findings refine the mechanistic framework of NeuroCOVID and identify translational priorities for acute and long-term neurological management.}, }

Since the onset of the pandemic, there has been a continuous rise in cases of both COVID-19 and long COVID. It is acknowledged that long COVID is a multisystem disorder with a wide range of symptoms; its primary symptoms and indicators include fatigue, dyspnea, anosmia, myalgia, cough, and hyposmia. SARS-CoV-2 has continuously evolved since the wild strain first appeared, resulting in numerous genetic variants. These strains exhibit significant differences in terms of pathogenicity and immune evasion. Key scientific questions remain regarding whether and how these variations influence the development and clinical course of long COVID.

There has been a growing emphasis on online recruitment strategies for most medical specialties. For the last several interview seasons, many national organizations have recommended that fellowship interviews be conducted virtually for all applicants. Social media represents a powerful tool for both the program and the applicants. However, there remains a paucity of data published on social media use for virtual recruitment in pulmonary and critical care medicine (PCCM). Here, we review the available data for virtual recruitment and propose best practices for PCCM programs. Our social media strategy outlines specific and practical steps that form the framework for a social media charter including defining the goal and audience, following institutional guidelines, choosing appropriate platform(s), identifying and defining an account management plan, devising a strategy for content generation and posting, and continuing to reassess and optimize the process. Our best practices provide a practice framework for PCCM programs, both novice and advanced, for social media use. They also emphasize a need for more research on social media's impact on future recruitment cycles while providing a better understanding of current practices for applicant program selection and virtual recruitment.}, }

Bushfires generate waves of air pollution with orders of magnitudes higher than normal background pollution, necessitating studies to understand the physiological impact. Previous work has strongly linked bushfire smoke to respiratory disease (chronic obstructive pulmonary disease COPD, asthma, lung cancer) cardiovascular disease (myocardial infarction, stroke), and increased susceptibility to infection (COVID-19). Nevertheless, the underlying mechanisms of pathogenesis remain unclear. There is little consensus on what in vitro and in vivo techniques are best used to examine disease mechanisms. Individual investigations are useful but a lack of standard methods creates variability and makes comparisons difficult. Developing adaptable in vitro and in vivo models that are replicable, physiologically relevant, and affordable may reduce variability enabling comparisons. These models should also be capable of integrating multiple types of pollutants or reference materials to develop standards that other studies can follow, facilitating comparisons. Here, we discuss advance in vitro and in vivo experimental models to study the impact of bushfire smoke exposure induced pathophysiology. The goal is to improve comparison and translation across studies, and to lay the groundwork for future research into the mechanisms that underpin bushfire smoke-induced pathogenesis to enable the development of preventative measures and effective therapies.}, }

The SARS-CoV-2 spike protein harbors a fatty-acid-binding pocket (FABP) at the interface between two adjacent receptor-binding domains. Ligand engagement at the FABP locks the spike into a non-infectious, closed conformation, thereby impairing the virus's ability to infect new cells. Herein, we summarize the small-molecule inhibitors targeting the FABP that have been described to date, analyzing their binding modes, SAR and mechanisms of action. Because this pocket is conserved across highly pathogenic coronaviruses, targeting it offers a promising strategy for developing novel antivirals with broad-spectrum anti-coronavirus activity. We hope this review will stimulate further research on FABP inhibitors and promote the discovery of broad-spectrum anti-SARS-CoV-2 therapeutics.}, }

The analysis incorporated macro-level determinants, including the Gini index, global quality infrastructure index, median age, and life expectancy. Multivariate meta-regression models was used to account for effect size dependencies, and heterogeneity was assessed using I[2] statistics. The systematic review and meta-analysis was pre-registered at http://www.crd.york.ac.uk (registration number: 651376).<br><br>RESULTS: The analysis included 50 studies encompassing >7 million individuals with some degree of overlap.

WHO recommends passive immunisation to protect infants younger than 6 months and, in some strategies, infants up to age 12 months, but detailed age data are needed to determine optimal timing and impact. Our study estimates age distributions for the full range of RSV outcomes among children younger than 5 years in LMICs.<br><br>METHODS: We conducted a systematic review and meta-analysis of RSV age distributions for seven health or health-care outcomes (hereafter, RSV outcomes): community cases, outpatient or clinic visits, emergency room visits, inpatient ward admissions, intensive care unit (ICU) admissions, facility deaths, and non-facility deaths. Inclusion required at least 30 laboratory-confirmed counts of RSV disease in children younger than 5 years, for a single RSV outcome from a single LMIC in the pre-COVID-19 decade (Jan 1, 2010, to Dec 31, 2019). We invited authors of included studies to share RSV counts by week or month of age. Using a Bayesian hierarchical model, we fitted parametric age distributions (by week for children <5 years) to each dataset, and derived pooled estimates of the mode, median, and mean age for each RSV outcome. The study was registered with PROSPERO (CRD42023435080).<br><br>FINDINGS: We included 160 datasets with 131&#x2008;124 RSV counts in children younger than 5 years.

Emerging evidence suggests that these changes are multifactorial, including altered contact patterns and immunity gap, disruptions and recovery in routine immunization and surveillance, waning or suboptimal vaccine-induced protection, pathogen adaptation, and improved case detection through expanded diagnostic capabilities. Addressing these challenges will require coordinated strategies to restore and optimize immunization delivery, strengthen surveillance and laboratory capacity (including resistance monitoring), and update clinical management guidance in the context of macrolide-resistant B. pertussis. Continued research is needed to define setting-specific drivers and to inform next-generation vaccines and integrated control strategies in the post-pandemic era.}, }

Propolis has been used as a traditional medicine for the treatment of depression and other neurological disorders. This review aims to investigate the clinical studies and various therapeutic potentials associated with propolis, direct the future scope of research, and discuss possible clinical implications. A total of 143 papers were selected using a database comprising Google Scholar, Scopus, PubMed, and Web of Science. Diverse keywords, such as propolis, bee, phytochemistry, pharmacology, and clinical study, were used to search the content. This review highlights the diverse biological activities of propolis, as evidenced by preclinical and clinical studies. In experimental models, propolis extract exhibited antidepressant-like and vasculoprotective effects, primarily through its anti-inflammatory and antioxidant potential. These benefits were associated with the suppression of pro-inflammatory cytokines, chemokines, and angiogenic factors. Propolis extract was found to delay the progression of atherosclerosis by improving lipid metabolism and modulating apoptosis. Furthermore, both in vitro and in vivo investigations suggest that propolis may protect vascular endothelial function due to its antiproliferative activity. Notably, anticancer potential was observed against the ovarian cancer cell line M12.C3.F6. Clinical studies also provided encouraging findings. In patients with type 2 diabetes mellitus, propolis extract has been shown to improve wound healing parameters in diabetic foot ulcers. Another trial reported promising outcomes with propolis extract formulated as niosomal oromucosal-adhesive films for recurrent aphthous ulcers. Overall, these results underline the multifaceted therapeutic promise of propolis across neurological, vascular, oncological, and wound-healing domains. This review summarizes clinical and experimental evidence on the therapeutic potential of propolis. It highlights its immunomodulatory, antioxidant, antimicrobial, antifungal, anticancer (skin, oral, lung, breast, cervical), antidepressant, anxiolytic, cardiovascular, chemopreventive, and anti-angiogenic properties. Several studies, including clinical trials, suggest its potential role in combating COVID-19 and other health conditions. Overall, findings indicate that propolis possesses significant medicinal promise and may serve as a lead candidate for developing novel therapeutic agents.}, }

Vaccination consistently altered amino acid pathways, specifically glutamine, phenylalanine, and tryptophan. Early activation of the kynurenine pathway (1-2 days post-dose) emerged as a predictor of stronger antibody responses. Inactivated vaccines triggered a "Warburg-like" metabolic switch, characterized by increased glycolysis and reduced TCA intermediates. Lipidomic changes were prominent; high baseline ceramides predicted low response, while sphingomyelins and short-chain fatty acids associated with positive immunity.

They experience distressing somatic complaints - such as fatigue, pain, headaches, and brain fog - lasting months or longer which impair quality of life and workability. In this article, we refer to these as persistent physical symptoms (PPS). When diagnosis, advice and care are based solely on a biomedical interpretation of symptoms, patients may not improve. This can result in repeated and often frustrating consultations and investigations. Aim: To outline contemporary theories around PPS for general practitioners, and offer practical, evidence-informed pathways to use in primary care. Methods: Narrative literature review and consensus development with experienced practitioners. Synopsis:Contemporary theories Contemporary theories of PPS provide a coherent framework for understanding symptom persistence and guide treatment. These theories propose that symptoms may arise from brain-based responses to perceived threat, influenced by expectations and learned associations. Such responses can become unhelpful when benign sensations are interpreted as dangerous. Biopsychosocial factors unique to each individual influence these mechanisms which need to be considered when assessing PPS and working towards symptom resolution with the patient. Evidence-informed pathways Key strategies include validating patients' symptoms and emotional experiences, providing clear explanations of symptom persistence, and developing personalised management plans that combine biological, psychological, and social approaches. Such strategies can reduce or resolve symptoms, foster hope and a sense of agency, and often lead to recovery.}, }

A less studied but equally important contributor to viral pathogenesis is viral dissemination, the capacity of a virus to move from the primary site of infection, traverse physiological barriers, and gain access to secondary sites of infection. This dictates viral tropism and pathogenesis, but the mechanisms governing barrier crossing are incompletely understood. While the presence of viral receptors on cells is a major determinant of viral tropism and a prerequisite for infection, it does not completely explain the capacity of viruses to enter a tissue. Our recent work has begun to characterize the contribution of soluble viral proteins, acting as "viral toxins," to viral dissemination, tissue tropism, and overall pathogenesis within an infected host. In this review, we discuss the characteristics of these viral toxins, which are soluble or surface-exposed viral proteins that can interact with endothelial and/or epithelial barriers, as well as immune cells, to trigger signaling pathways, resulting in the transient breakdown of cellular structures maintaining barrier integrity. The disruption of these barriers induces vascular leak and facilitates virus dissemination, influencing viral tropism and pathogenesis. Importantly, blocking this process prevents leak, viral dissemination, and severe disease during infection, highlighting the value of therapeutic intervention against viral toxin activity. Here, we summarize our current understanding of recently discovered viral toxins from the Flaviviridae, Coronaviridae, Nairoviridae, and Filoviridae.}, }

Data from UNAIDS, the World Health Organisation (WHO), and peer-reviewed literature were analysed to assess HIV service delivery in SSA from 2019 to 2024, with special attention to regional disparities and health system adaptations before, during, and after the pandemic. Before the COVID-19 pandemic, Southern and Eastern Africa were nearing the 90-90-90 goals while West and Central Africa made slower progress because of weaker health systems and other situational challenges. Between 2020 and 2022, lockdowns and service disruptions reduced HIV testing, delayed the start of antiretroviral therapy (ART), and led to fewer viral load analyses. To adapt, health systems provided ART for longer periods, offered more community-based care, expanded health worker roles, and used digital tools to maintain services, especially where infrastructure was strong. By 2023 and 2024, most countries in Southern and Eastern Africa were closer to achieving the 95-95-95 targets, while West and Central Africa continued to recover more slowly. The pandemic revealed both strengths and weaknesses in the HIV response in sub-Saharan Africa.

The delivery system has evolved from a passive transporter into an active immunomodulatory component, a critical component that (1) protects the inherently fragile mRNA payload, (2) allows cellular uptake and endosomal escape, and (3) adds its own inherent adjuvant properties to shape the immune response. This review provides a comprehensive summary of the current advancements in mRNA vaccine delivery technologies. We first deconstruct the structure, mechanisms, advantages, and disadvantages of the clinically validated LNP platform. Following this discussion, we highlight the emerging landscape of new systems, including chemically diverse polymeric nanoparticles, biologically-inspired peptide-based carriers, and endogenous extracellular vesicles, potentially overcome current limitations in these delivery systems, including issues with thermostability and targeted delivery. After this, we summarize how these new delivery technologies are being leveraged clinically for a continuum of high-priority infectious diseases, including influenza, RSV, CMV, HIV, Zika, and Rabies.

Macrolides have long been first-line therapy due to favorable safety profiles and low minimum inhibitory concentrations (MICs) in pediatric populations. However, the global surge in macrolide-resistant MP (MRMP) has compromised conventional treatments, creating an urgent need for alternative agents. Mounting evidence supports doxycycline, a second-generation tetracycline, as an effective therapy for pediatric MRMP, particularly post-COVID-19. Compared to azithromycin, doxycycline shortens disease duration, accelerates the resolution of fever and cough, promotes pulmonary infiltrate absorption, and yields robust outcomes in children ≥8 years old. It also reduces corticosteroid use and exhibits a favorable safety profile. For refractory MP pneumonia (RMPP), combination therapy with doxycycline and corticosteroids (eg, methylprednisolone) enhances therapeutic effects. Ongoing research explores innovative combinations and personalized dosing to mitigate resistance. This narrative overview synthesizes recent advances in doxycycline use for pediatric MRMP since the COVID-19 pandemic, aiming to inform evidence-based practice.

However, increasing evidence indicates that ivermectin can produce clinically relevant toxicity under specific conditions, particularly involving the central nervous system. This review integrates findings from controlled human trials, pharmacovigilance data, clinical case reports, experimental animal studies, and environmental investigations to comprehensively characterize the toxicological profile of ivermectin. Early randomized, placebo-controlled studies in healthy volunteers demonstrated that ivermectin is generally well tolerated, even at doses substantially exceeding approved therapeutic levels, with predominantly mild and transient adverse events and no significant neurological toxicity under controlled conditions. In contrast, post-marketing surveillance and real-world clinical reports have identified rare but severe neurotoxic events, including encephalopathy, seizures, coma, and death, occurring after supratherapeutic exposure and, in susceptible individuals, even at standard therapeutic doses. Converging human and animal evidence highlights impairment or saturation of blood-brain barrier protection, particularly dysfunction of P-glycoprotein (ABCB1/MDR1)-mediated efflux, as a central determinant of ivermectin neurotoxicity. Animal studies further demonstrate marked species-, breed-, age-, dose-, and route-dependent susceptibility, with neonatal animals, genetically predisposed dog breeds, and models exposed to transporter inhibition or repeated high-dose regimens showing pronounced vulnerability. While neurotoxicity is often functional and reversible at lower exposures, high or cumulative dosing can lead to structural neuropathology and multi-organ injury. The COVID-19 pandemic amplified these risks through widespread off-label use, especially of veterinary formulations, resulting in a substantial increase in toxic exposures without demonstrated clinical benefit. Overall, ivermectin toxicity emerges as a predictable consequence of interactions between pharmacokinetics, transporter biology, exposure patterns, and host-specific factors rather than an inherent contradiction of its therapeutic value.}, }

Current product labeling recommends caution with vaccine administration in patients taking these medications, particularly live-attenuated vaccines, despite limited evidence of actual risk. Objective: The objective was to review clinical concerns and available evidence, and to provide practical recommendations for vaccination in patients receiving biologics for atopic diseases, with a focus on dupilumab. Methods: A comprehensive PubMed/MEDLINE literature search was conducted to identify relevant studies and clinical guidance with regard to vaccination strategies in patients receiving biologic therapy. The primary search terms included the following: "biologic therapy" or "biologic therapy" or "monoclonal antibodies" combined with "vaccination" or "immunization" or "vaccine response" or "live vaccines" or "inactivated vaccines." Priority was given to randomized controlled trials, large observational studies, and registry data published within the past 10 years. Results: For non-live vaccines, evidence supports safety and efficacy, although results of some studies suggest moderately reduced responses. A randomized controlled trial found comparable antibody responses between dupilumab and placebo groups for tetanus (83.3% versus 83.7%) and meningococcal vaccines (86.7% versus 87.0%). Coronavirus disease 2019 (COVID-19) vaccine studies show mixed results, with some reporting lower antibody levels and neutralization capacity in patients on biologics. For live-attenuated vaccines, emerging evidence challenges traditional prohibitions. Conclusion: Current evidence supports the safety and efficacy of non-live vaccines in patients receiving biologics for atopic diseases, although responses may be moderately reduced. Analysis of emerging data suggests certain live-attenuated vaccines may be safer than previously thought, particularly in pediatric patients on dupilumab. Vaccination decisions should be individualized based on risk-benefit assessment. Further research is needed to establish definitive guidelines, particularly for live vaccines and long-term immunity.}, }

Although individual countries retain distinct systems for resident recruitment, training structure, and surgical exposure, the overarching goal has been to converge toward competency-based education guided by the European Board of Ophthalmology (EBO) and the European Union of Medical Specialists (UEMS). This narrative review draws on official EBO and UEMS policy documents, recent peer-reviewed literature, national curricula, and surveys of residents and educators. It examines the structure and duration of training, curriculum reforms, surgical exposure, simulation, fellowship opportunities, and the influence of European legislation on professional mobility. Residency programs in Europe vary in length from four to six years, with considerable heterogeneity in surgical case volume, fellowship opportunities, and access to simulation. The 2024 European Training Requirements (ETR) introduced Entrustable Professional Activities (EPAs), programmatic assessment, and e-portfolios, providing a common reference for national curricula. The EBO Diploma (EBOD) serves as a recognized benchmark for harmonization. Simulation-based cataract training has moved from optional to integral, though adoption remains inconsistent. Pressures such as the European Working Time Directive (EWTD) and the COVID-19 pandemic have altered clinical exposure, while digital education and mobility programs offer compensatory mechanisms. European ophthalmology training is moving toward harmonized outcomes but retains structural variation between countries. Achieving consistency will require aligning national curricula with the ETR, mandating simulation milestones, investing in faculty development, and formalizing fellowship standards to ensure equitable access and readiness for independent practice.}, }

However, given its potential severity, it is essential to incorporate the different phenotypes into the diagnostic and therapeutic approach to common pediatric diseases and syndromes to minimize both underdiagnosis and overtreatment. The Kawasaki disease phenotype of MIS-C (fKD/MIS-C) and Kawasaki disease (KD) require special attention, as they share multiple clinical and pathophysiological characteristics. While the current evidence on KD is robust regarding treatment, severity, and outpatient follow-up, MIS-C management relies predominantly on expert recommendations. It is crucial to recognize the key common and distinctive features of these entities to optimize diagnosis, identify at-risk groups, and improve therapy during the acute phase and outpatient follow-up. Nonetheless, the long-term implications of fKD/MIS-C have not yet been fully elucidated.}, }

We constructed a taxonomy distinguishing narrow health-related from broader societal values, and traditional from novel values. Value elements in the taxonomy included improved health and reduced treatment costs; improved productivity; improved strain selection, raising vaccine efficacy; greater compliance with vaccine schedules, increasing uptake; improved patient and caregiver health and reduced treatment costs from such greater efficacy and uptake; reduced adverse events, anxiety and vaccination costs from reduced doses; process utilities from increased convenience; higher patient and provider acceptability; increased equity; and health-related R&amp;D spillovers.<br><br>LIMITATIONS: The TLR was non-systematic.

As SARS-CoV-2 continues to evolve, wastewater surveillance has expanded beyond quantifying total viral RNA to also resolving signature mutations and mixed lineage compositions in complex matrices. This review synthesizes end-to-end workflows for variants-directed WBE, spanning sample collection and viral signal enrichment, sequencing-dependent approaches (tiled-amplicon and hybrid-capture sequencing coupled with lineage deconvolution of mixed samples), and sequencing-independent approaches based on targeted mutation detection, including RT-dPCR, allele-specific RT-qPCR, and nested-PCR coupled with LC-MS. We compare these modalities in terms of resolution, sensitivity, turnaround time, and operational constraints, and highlight recurrent bottlenecks such as uneven genome coverage, low-frequency mutation detection, primer/assay drift, and the need for robust quality control and benchmarking under real wastewater conditions. To reduce end-to-end latency and improve sustainability, we outline requirements and research priorities for integrated, automated on-site (or near-site) monitoring systems, emphasizing compact enrichment/extraction modules, field-deployable detection chemistries, and rapid reporting pipelines. Finally, we extend the COVID-era framework beyond SARS-CoV-2, discussing how wastewater and environmental surveillance can be institutionalized as a multi-hazard public health intelligence platform supporting multiplex respiratory panels, pathogen-agnostic sequencing for anomaly detection, mobility-linked sentinel networks, and One Health applications such as antimicrobial resistance monitoring.}, }

While most studies examine inequities in general healthcare utilization, few focus specifically on NCDs services. This review addresses that gap by synthesizing evidence on associated factors of equitable NCDs service utilization and assessing interventions to improve utilization.<br><br>METHODS: A systematic review and meta-analysis were conducted following PRISMA-Equity guidelines, including studies published between 2014 and 2024. Eligible studies examined socioeconomic and demographic associated factors of NCDs service utilization or evaluated interventions to reduce inequities. In the meta-analysis, pooled estimates for NCDs service utilization were performed using a random effects model. Heterogeneity among studies was assessed using I&#xb2; statistics.<br><br>RESULTS: Twenty-three studies were included. Overall, NCDs service utilization showed a clear pro-rich pattern, with wealthier groups consistently utilizing more services. The pooled outpatient NCD service utilization was 52.84% (95% CI: 41.04&#x2013;64.64). Compared with the poorest wealth quintile, higher wealth status was significantly associated with greater NCDs service utilization (AOR&#x2009;=&#x2009;1.44; 95% CI: 1.18&#x2013;1.74).

This review critically analyzes existing literatures on SCLM applications, focusing on key parameters such as lung elastance (E), airway resistance (Rrs), and Dynamic Functional Residual Capacity (dFRC). Methodologies, evaluation metrics, and clinical applications were examined to identify common trends, inconsistences, and research gaps. The findings indicate that E has been the primary focus due to its relevance in assessing lung mechanism, especially under MV. This parameter often evaluated alongside variables like Positive End-Expiratory Pressure (PEEP), Peak Inspiratory Pressure (PIP), Peak Inspiratory Volume (PIV), and Tidal Volume (Vt). Additionally, FRC and Rrs are also considered in some models.

While these exposures typically produce only small pH shifts in healthy adults, older individuals exhibit age-related declines in respiratory, renal, metabolic, and proteostatic resilience that reduce their ability to buffer such disturbances. Because even mild acidosis can influence protein folding and accelerate amyloid formation under conditions of impaired homeostasis, aging populations may be disproportionately susceptible to downstream effects of chronic low-grade CO2 exposure.<br><br>METHODS: This narrative review synthesizes data on age-related changes in ventilation, acid-base regulation, metabolic buffering, and proteostasis, integrating these with biochemical pathways of pH-dependent amyloidogenesis. Evidence from mask-related CO2 exposure studies, protein-misfolding research, and gerontological physiology was analyzed to evaluate whether age-specific vulnerability could plausibly modulate amyloidogenic risk.<br><br>RESULTS: Across multiple studies, mask wearing increases inhaled CO2 concentrations and produces small but measurable reductions in blood pH in some conditions. Although these changes remain within normal physiological range in healthy adults, aging is associated with impaired ventilatory responsiveness to hypercapnia, diminished renal compensation, reduced muscle-based buffering due to sarcopenia, and mitochondrial and proteostatic decline. These changes lower physiological reserve and may magnify the biological impact of minor pH fluctuations. Experimental literature consistently demonstrates that acidity accelerates amyloid formation in proteins relevant to aging disorders-including A&#x3b2;, &#x3b1;-synuclein, IAPP, and &#x3b2;2-microglobulin-while older adults also accumulate comorbidities (chronic kidney disease, diabetes, neurodegeneration) that themselves predispose to acidosis and amyloidogenic stress.<br><br>CONCLUSIONS: Although mask-associated CO2 elevations appear insufficient to induce amyloid formation in isolation, the combination of age-related physiological decline, chronic inflammation, impaired proteostasis, and reduced buffering capacity may heighten vulnerability in older adults. Given global demographic aging, further age-stratified research is needed to clarify long-term implications of repeated low-grade hypercapnia, refine diagnostic approaches for early detection of proteostatic stress, and develop prevention strategies tailored to aging physiology.}, }

Despite decades of research, its extra-skeletal effects remain controversial, largely due to discordant findings across observational studies, Mendelian randomization studies (MRS), and randomized controlled trials (RCTs). Unlike many prior reviews, this state-of-the-art review synthesizes triangulated evidence across these study designs to clarify outcome-specific causal relationships and ongoing controversies.<br><br>RECENT FINDINGS: Triangulated evidence provides strong and consistent support for a causal role of vitamin D in skeletal health, particularly in the prevention and treatment of rickets and osteomalacia, and in fracture risk reduction among vitamin D&#x2013;deficient and older populations. For selected extra-skeletal outcomes, modest and threshold-dependent benefits are observed, including reductions in cancer mortality, protection against autoimmune disorders, most convincingly multiple sclerosis, and decreased risk of acute respiratory infections, including COVID-19, primarily in individuals with low baseline 25(OH)D concentrations. In contrast, associations with cardiovascular disease, metabolic disorders, obesity, and most neuropsychiatric outcomes are not consistently supported by genetic or interventional evidence, suggesting limited or non-causal effects. Across outcomes, evidence indicates a non-linear relationship between vitamin D status and health, with increased risk concentrated at low 25-hydroxyvitamin D concentrations and limited benefit beyond sufficiency. All-cause mortality shows a modest, threshold-dependent association, with supplementation benefits largely confined to deficient or older populations. Key challenges include assay variability, non-linear dose&#x2013;response relationships, and RCT designs that frequently enroll vitamin D&#x2013;replete populations, resulting in substantial methodological heterogeneity and limiting causal inference.<br><br>SUMMARY: Overall, the presented triangulated model may reconcile longstanding inconsistencies by reframing vitamin D as a context-dependent determinant of health. These findings argue against indiscriminate population-wide supplementation and support targeted strategies focused on the identification and correction of deficiency. Vitamin D should be regarded neither as a universal panacea nor as a trivial supplement, but as a context-dependent hormone whose clinical value lies in outcome-specific correction of deficiency.<br><br>GRAPHICAL ABSTRACT: Created in BioRender by Dimitra Petropoulou (January 20, 2026) BioRender.com/rd3udxs.

Other factors such as stress (n = 113), trauma, sunburn, smoking, diet, and sleep were frequently cited but supported by lower-level evidence. Study heterogeneity, a lack of standardized outcomes, and the predominance of observational designs limited meta-analysis and causal inference.<br><br>CONCLUSIONS: These findings highlight the environmental triggers of vitiligo onset and progression. Drugs, chemicals, and infections are key triggers; lifestyle factors require further study.}, }

Most (68%) had a retrospective design in which participants were asked to recall contacts that occurred prior to survey administration and 73% used a single-survey cross sectional design using random (16%) or stratified random (44%) sampling. Relevant contacts were often defined by an exchange of words (77%) or physical touch (59%). A minority of studies differentiated between contacts that occurred outdoors vs. indoors (28%) or allowed participants to report large group contacts separately from individually named contacts (28%).

This article thoroughly examines the complex connection between environmental degradation and the development of new viral diseases. Human activities, such as deforestation, urbanization, and industrial agriculture, have significantly altered ecosystems, increasing the likelihood of virus transmission from animals to humans. The alteration of natural environments brings wildlife species that serve as hosts for several viruses into closer proximity to human populations, thereby promoting the transmission of zoonotic diseases. In addition, climate change and pollution worsen the susceptibility of both animal and human societies to viral epidemics by compromising immune responses and changing the distribution of disease carriers. This paper examines how environmental degradation is associated with viral emergence, drawing on case studies including HIV, Ebola virus disease, and COVID-19, to illustrate shared spillover mechanisms. Evidence from major zoonotic outbreaks, including HIV, Ebola virus disease, and COVID-19, indicates that environmental degradation acts through shared mechanisms, notably habitat fragmentation, biodiversity loss, and intensified human–animal interfaces. Epidemiological and ecological investigations suggest that forest encroachment, wildlife exploitation, and land-use change consistently increase opportunities for viral spillover, underscoring environmental stewardship as a critical component of pandemic prevention. This emphasizes the importance of adopting comprehensive strategies that combine environmental protection with public health efforts to lower the risk of future pandemics. It highlights the need for coordinated global action that integrates ecosystem conservation with public health preparedness to reduce future zoonotic disease risk.}, }

However, while organizational agility has received considerable scholarly attention, research on employee agility as its micro-foundation remains limited and fragmented, leaving substantial gaps in understanding the individual-level factors that shape organizational adaptability. This study presents a comprehensive bibliometric review of research on employee agility over the past 25 years, aiming to map its intellectual, conceptual, and social structures, identify gaps in the existing literature, and outline future research directions. The analysis encompasses 319 publications indexed in Scopus and Web of Science, spanning the period from 2000 to 2025. Using Biblioshiny and VOSviewer, the study examines publication trends, citation networks, thematic structures, and emerging research frontiers. The results reveal a sharp increase in publications since 2020, driven by the COVID-19 pandemic and digital transformation pressures. Three main clusters dominate the field: (1) organisational responses to change and disruption, (2) HRM practices and individual-level mechanisms, and (3) collaboration, knowledge sharing, and digital platforms. Despite these developments, significant gaps remain, including the limited integration of leadership, weak linkage between employee agility and innovation, the divide between HR-driven and digital-driven agility, and the underrepresentation of studies in the public sector and Southeast Asia. By synthesising fragmented insights across two major databases, this study highlights employee agility as a micro-foundation of organisational agility and proposes future research directions focusing on leadership, digital competence, innovation, psychological factors, and public sector contexts. These contributions position employee agility as not only a short-term adaptive capability but also a strategic enabler of innovation and sustainability in dynamic environments.}, }

Transmission of pathogens by flies in the Stomoxys genus is largely mechanical, indicating that they can transmit a wide range of pathogens to a variety of hosts. This study evaluated the diversity of pathogens demonstrably transmitted by a variety of Stomoxys flies, concerning species diversity, host diversity, and geographic distribution. Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines were applied to screen studies based on pathogen type, host species, and experimental transmission outcomes. Journal articles published from 1973 to 2025 were sourced from six electronic databases. After evaluation, 30 studies were eligible for this review. Of these studies, 20% (6/30) reported negative outcomes. Three pathogens (Middle East respiratory syndrome coronavirus, Neorickettsia risticii, and Escherichia coli) were not transmitted by the flies in the experiments. Stomoxys spp. transmitted pathogens to a wide range of hosts (9 mammals) and substrates (blood and tissue culture), but the recorded experiments in camels failed. Three out of ten Stomoxys spp. reported in the studies (S. transvittatus, S. inornatus, and S. omega) failed to transmit pathogens in all attempts. The majority of experimental studies were on S. calcitrans, with very limited studies on other Stomoxys species, highlighting the dearth of information on other species occurring in Africa and Asia. Our study has consolidated the evidence regarding the experimental pathogen transmission by Stomoxys spp., highlighting and demonstrating their epidemiological significance and the need for surveillance and control/prevention strategies.}, }

Moreover, different viruses were shown to be captured by CD169+ cells which could play distinctive role during infections: they could enhance efficient immune responses, but also facilitate pathogen dissemination through viral capture and transfer to permissive cells. This last mechanism has been well documented for HIV-1, where CD169 mediates viral trans-infection of CD4[+] T-cells. CD169 expression is rapidly induced by type-I interferons during acute viral infections and has emerged as a valuable biomarker to distinguish viral from bacterial infection, particularly for COVID-19 and influenza.

However, the prevalence and associated factors among Chinese college students require an updated synthesis. This study aimed to estimate the pooled prevalence of sleep disturbance in this population and to examine potential sources of between-study variation.<br><br>METHODS: A systematic search was conducted in four Chinese databases (CNKI, Wanfang, VIP, and Sinomed) and five international databases (PubMed, EMBASE, Web of Science, Cochrane Library, and PsycINFO) from inception to December 22, 2025. The study protocol was pre-registered in PROSPERO (CRD420251270413). Cross-sectional studies reporting sleep disturbance among Chinese college students assessed using the Pittsburgh Sleep Quality Index were included, with no restrictions on cut-off thresholds. Recall timeframes included the past month, 1&#x2013;2 weeks, or several months. Random-effects meta-analysis was used to pool prevalence estimates with 95% confidence intervals, and a 95% prediction interval was additionally reported for the overall pooled estimate to reflect between-study heterogeneity. Statistical heterogeneity was assessed using the I&#xb2; statistic. Subgroup analyses were performed to explore methodological and population-level factors, and between-group differences were tested using chi-square statistics.<br><br>RESULTS: A total of 232 studies involving 495,641 undergraduate students were included. The pooled prevalence of sleep disturbance was 26.4% (95% confidence interval: 24.6% to 28.3%, 95% prediction interval: 7.4% to 59.1%), with substantial heterogeneity (I&#xb2; = 99.57%). Methodological factors were significantly associated with prevalence estimates, particularly the Pittsburgh Sleep Quality Index cut-off score and the recall timeframe (both P&#x2009;<&#x2009;0.001). Prevalence was highest during the COVID-19 pandemic (33.5%), compared with the pre-pandemic period (24.1%) and the post-pandemic period (21.0%) (P&#x2009;=&#x2009;0.001). Higher pooled estimates were observed in more recent publication periods, increasing from 22.9% in 2014 and earlier to 28.7% in 2020 and later (P&#x2009;=&#x2009;0.018). No statistically significant differences were identified across gender, academic year, major, region, or only-child status. Higher prevalence was observed among smokers, drinkers, and students reporting poorer family economic status, although these differences did not reach statistical significance.<br><br>CONCLUSIONS: Sleep disturbance, as defined by the Pittsburgh Sleep Quality Index, is prevalent among Chinese college students. Estimates should be interpreted cautiously because of extreme heterogeneity and reliance on self-reported, predominantly cross-sectional data. The findings underscore the public health relevance of sleep health on campuses and support continued monitoring and health promotion, as well as more standardized measurement in future studies.<br><br>CLINICAL TRIAL NUMBER: Not applicable.<br><br>SUPPLEMENTARY INFORMATION: The online version contains supplementary material available at 10.1186/s12888-026-07997-z.}, }

The COVID-19 pandemic revealed critical weaknesses in the country's surveillance systems, diagnostic capacity, and outbreak response, underscoring the urgent need for stronger pandemic preparedness and a transition from a reactive, crisis-driven model to a proactive, prevention-focused health system. This study synthesizes existing literature, policy documents, and recent evaluation reports to assess Indonesia's health system performance in RID management and to identify evidence-based priorities for reform. The analysis is structured around five health system components: (1) surveillance and early warning, (2) diagnostic and laboratory capacity, (3) healthcare workforce, (4) public health infrastructure and primary care, and (5) governance and financing. Indonesia demonstrates important strengths, including a nationwide network of more than 10,000 Primary Health Centers (Puskesmas) and proven vaccination campaign capacity. However, significant gaps persist: during COVID-19, Early Warning Alert and Response System (EWARS) reporting completeness dropped from 75% to 53%, rural and remote areas remain underserved by diagnostics, and health workforce distribution continues to be inequitable Priority reforms include scaling up point-of-care diagnostics across all Puskesmas, integrating fragmented surveillance platforms through SatuSehat, empowering community health workers with digital tools, and ensuring sustainable financing for preparedness. Medium-term strategies focus on workforce redistribution and the establishment of regional health security centers, while long-term priorities emphasize predictive health intelligence, resilient supply chains, and nationwide facility upgrades. Building a resilient, prevention-oriented system will require sustained political commitment, innovative financing, and cross-sectoral collaboration, positioning Indonesia not only to strengthen domestic health security but also to serve as a regional leader in epidemic preparedness.}, }

The pathology of Alzheimer's disease (AD), the most common form of dementia, has been linked to the presence of plaques and neurofibrillary tangles in the central nervous system of patients. There are growing indications that risk of developing dementia correlates with several infectious agents, including human herpes viruses, flaviviruses and SARS-CoV-2. This has led to a proposition that AD and other dementias could be considered as having an infectious disease etiology. Whilst the mechanisms behind this remain unclear, intriguing epidemiological data suggest that several vaccinations are correlated with reduced risk for dementia. Intravesicular administration of the tuberculosis vaccine strain Bacille Calmette-Guérin (BCG) has been associated with decreased risk of dementia in bladder cancer patients. This has led to the hypothesis that non-specific effects of vaccinations, mediated through trained innate immunity, provide a mechanistic explanation. Over the last few years, the AS01-adjuvanted recombinant shingles vaccine has also been associated with reduced risk in several studies. Moreover, in a recent study, immunization with the adjuvanted RSV vaccine, also containing AS01, was shown to reduce risk of dementia. Integrating data on BCG and mechanistic hypotheses, recent findings on the AS01 adjuvant, and the role of trained innate immunity, we describe here an immunological model that connects vaccine and adjuvant mode of action with risk of dementia. This immunological model can help shape a research roadmap to further elucidate the mechanisms behind the collective epidemiological data.}, }

A key pathological outcome of PEDV infection is the induction of oxidative stress, which significantly exacerbates intestinal injury and accelerates disease progression. Natural bioactive compounds, sourced from plants, animals, and microorganisms, have been extensively studied for their diverse biological properties, including potent antioxidant, anti-inflammatory, and antiviral activities. These compounds demonstrate significant potential in alleviating oxidative stress and playing a pivotal role in the prevention and management of PEDV infections. This review provides a comprehensive analysis of the mechanisms by which natural bioactive compounds enhance the antioxidant defence system and suppress PEDV replication. Current evidence indicates that these compounds alleviate oxidative stress primarily through the modulation of antioxidant enzyme systems, such as superoxide dismutase (SOD) and glutathione peroxidase (GPx), and the activation of key signalling pathways, including the Nrf2/ARE axis. These actions collectively contribute to reduced viral loads and improved health outcomes in PEDV-infected pigs. Although these findings underscore the potential of natural bioactive compounds, several critical challenges persist, particularly the incomplete elucidation of their mechanisms of action and the substantial costs associated with large-scale applications. Addressing these challenges necessitates further research aimed at uncovering the precise molecular pathways underlying their effects and developing cost-effective strategies to facilitate their practical implementation in the swine industry.}, }

In this context, can we truly balance the benefits and risks of medications? The experience of Covid-19 illustrates the complexity of this concept.

Long COVID continues to challenge healthcare systems, with many healthcare professionals reporting uncertainty about assessment and referral pathways. This updated review examines recent international guidelines alongside Australian services to identify gaps between guidelines and practice.<br><br>METHODS: Between April and October 2025, we searched for guidelines on Long COVID published in English and assessed their quality by applying the AGREE II appraisal tool. We also conducted a grey literature search to profile active Australian services providing Long COVID care.<br><br>RESULTS: Three new or updated guidelines were published in the United States, Canada, and New South Wales, Australia. Together with the World Health Organisation, United Kingdom and New Zealand guidelines identified in the previous review, all emphasise integrated, primary care-led approaches. Notably, Australian service delivery remains fragmented, with a growing number of primary health practitioner-led private services operating largely under a fee-for-service model, leading to variations in access and affordability. Many hospital-based outpatient clinics have been absorbed into existing chronic-disease services. The most fundamental challenge is statistical invisibility: without an activated diagnostic code, services cannot reliably identify or follow people living with Long COVID. This invisibility limits both surveillance and service planning.<br><br>DISCUSSION AND CONCLUSIONS: Australia is currently developing national clinical best-practice guidelines for ME/CFS, which may also benefit Long COVID; however, Australia remains behind comparable nations such as Canada, the United Kingdom, and the United States in developing and implementing the integrated, multidisciplinary care models recommended internationally. This has significant implications, namely that the rapid transition from hospital-based Long COVID clinics to primary care-led services has resulted in fragmented and uncoordinated care. Strengthening Australia&#x2019;s response will require national leadership and investment in workforce training, sustainable funding for care coordination, improved public and professional awareness, the establishment of primary care-led multidisciplinary pathways, and the activation of a dedicated diagnostic code. Also importantly, shifting to a patient-centred approach and patient-practitioner collaborative model of care is essential to prepare the health system for managing Long COVID and future complex, multi-system conditions.<br><br>SUPPLEMENTARY INFORMATION: The online version contains supplementary material available at 10.1186/s12913-026-14268-w.}, }

To date, no systematic review has examined long-term trends in screen time use among children and adolescents that cover periods before and after the onset of the COVID-19 pandemic. This systematic review examined repeated cross-sectional studies to determine whether screen time use among children and adolescents changed over time. This systematic review was registered with PROSPERO (ID: CRD42021243869). The Web of Science, PubMed, Embase, and PsycINFO databases were searched to identify peer-reviewed studies that had been published in English, included data from at least two time points, and focused on children and adolescents between 0 and 19 years of age. The search was conducted without any restrictions on publication year. This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Study quality was assessed using the Quality Assessment Tool for Studies with Diverse Designs. A narrative synthesis was conducted following the Synthesis Without Meta-analysis guidelines. This review identified 60 studies covering the period 1991-2022. The findings indicate that traditional TV watching declined while the use of computers and video games grew. Screen time increased significantly over the years, especially after the COVID-19 pandemic started. The studies reviewed varied in how they defined and measured screen time. The review underscores the importance of continued research and evidence-based policies to guide responsible technology use in the lives of young people.}, }

We investigated the effects of SARS-CoV-2 on various semen parameters, including semen volume, sperm concentration, sperm total count, total motility, progressive motility, morphology, and DNA fragmentation index (DFI). A literature review was conducted on all studies evaluating the impact of SARS-CoV-2 infection on male infertility from the beginning of 2019 through December 2023. Main electronic databases such as PubMed, Scopus, Cochrane Library, and Web of Science were used. The research question was based on the PECO framework, focusing on (Population) exposed to SARS-CoV-2 (Exposure), compared to uninfected men (Comparator), with conventional sperm parameters as the measured Outcome. The studies were divided into two groups for analysis: between-group comparisons, which compared sperm parameters of men recovered from COVID-19 to uninfected controls, and within-subject comparisons, which assessed sperm parameters in the same individuals before and after infection. Standardized mean differences (SMD) were calculated as effect sizes with 95% confidence intervals (CI) for each outcome. The DerSimonian-Laird method estimated between-study variance (τ[2]), while the Jackson method calculated confidence intervals for τ[2] and τ. Publication bias was assessed using funnel plots and Egger's test. This meta-analysis included two types of cohort studies: single-arm studies and those with a control group. In the single-arm studies, a statistically significant decrease in semen volume (p = 0.0023) was observed. Additionally, in the cohort studies with controls, there were statistically significant reductions in sperm concentration (p < 0.0001), total count (p = 0.0001), total motility (p = 0.0009), progressive sperm motility (0.0391), and DFI (0.04). This is the most up-to-date systematic review and meta-analysis incorporating cohort study data.

Emerging evidence shows that residual SARS-CoV-2 antigens, host-derived alarmins, reactivated latent viruses, and mucosal microbiome-derived products from oral-nasopharyngeal and gut reservoirs sustain the chronic activation of pattern-recognition receptors, inflammasomes, and complement pathways. In parallel, deficits in specialized pro-resolving mediators, impaired efferocytosis, and persistent tissue injury prevent physiological termination of inflammation. These unresolved cues drive long-lasting epigenetic and metabolic reprogramming of hematopoietic stem cells and myeloid lineages, creating maladaptive trained immunity states characterized by hyper-responsiveness or exhaustion of these cells. Thromboinflammatory processes, including aberrant NETosis and sustained interface signalingling, further reinforce self-perpetuating inflammatory circuits. Together, these pathways give rise to reproducible molecular endotypes, including thromboinflammatory, interferon-driven, and neuroinflammatory phenotypes, which explain clinical heterogeneity. Framing PASC as a disorder of impaired immune resolution within a mucosal microbial viral context provides a unifying mechanistic scaffold for biomarker identification and host-directed therapies. This review proposes that restoring active resolution programs, rebalancing metabolic-epigenetic networks, and dismantling pathogenic innate feedback loops are promising strategies for reversing the chronic immune imprint of PASC.}, }

Among these, loneliness and chronic diseases were consistently significant risk factors for depression in the elderly, and the strength of the association between loneliness and depression was further enhanced in the post-pandemic period. Notably, the significant association between female gender and depression observed in the pre-pandemic period no longer existed in the post-pandemic period. This change is speculated to be related to adjustments in the coverage of social support after the pandemic, which requires further verification in subsequent studies. Based on the above association characteristics, targeted intervention measures can be adopted in the post-pandemic period, such as striving to alleviate loneliness in the elderly, strengthening health monitoring for key groups including the elderly living alone and those aged&#x2009;&#x2265;&#x2009;70&#xa0;years, and promoting the organic integration of chronic disease management and psychological assessment, so as to effectively reduce the risk of depression in the elderly.<br><br>SUPPLEMENTARY INFORMATION: The online version contains supplementary material available at 10.1186/s12877-026-07088-4.}, }

There is a range of SDL study techniques employed by medical students on placement. The COVID-19 pandemic accelerated the adoption of digital resources, prompting a need to reassess the study techniques that best support clinical-year medical students. However, there is a lack of research on which study techniques Australian clinical-year medical students find most effective. The objective of this study is to evaluate the evidence on student-perceived utility of common study techniques for SDL whilst on clinical placement in Australia. A qualitative scoping review of literature on PubMed and Medline Ovid was performed in 2024. Study inclusion criteria for articles were published articles, English language, publication within 20 years, and focus on clinical-year medical students. Exclusion criteria were review articles, investigations focusing on a specific educational intervention, and studies including only pre-clinical students. Studies were qualitatively appraised and synthesised by tabulation in Microsoft Excel (Microsoft Corp., Redmond, WA, US). Risk of bias analysis was not performed. Nine studies from Australia, the USA, the UK, Thailand, Saudi Arabia, and Malaysia were analysed. This included seven cross-sectional, one mixed-methods, and one qualitative analysis. Sample size ranged from 12 to 350 students. Only two studies were conducted after the COVID-19 pandemic. Overall, the results of the included studies demonstrate a consistent trend towards third-party online tools, including question banks, mobile applications, and revision courses for SDL. The strength of evidence on students' perceived efficacy of study techniques in the post-pandemic era presented is limited due to the small number of included studies and the lack of formal study appraisal. There is also poor generalisability of pre-pandemic and international studies to the contemporary Australian context. As there is a lack of a standardised tool to evaluate study technique utility, comparison between studies is difficult. Ongoing research is required to develop evidence-based guidelines that can assist students in commencing SDL whilst on clinical placement.}, }

Eligible studies included human investigations and relevant animal models reporting genetic, epigenetic, or molecular alterations in autophagy, telomerase, or endothelial pathways with cardiovascular relevance. Non-English publications, studies lacking primary data, and reports unrelated to cardiovascular or systemic disease mechanisms were excluded.

This systematic review and meta-analysis examines pooled prevalence estimates of probable PTSD among this cohort prior to COVID-19 compared to during COVID-19 and investigates time trends in prevalence. Systematic multi-database literature searches were conducted to identify studies published between January 2017 and July 2023. Included studies reported the prevalence of probable PTSD, measured by validated screening tools, in clinical healthcare workers. Two reviewers independently conducted study screening, data extraction, and quality assessment. Random-effects meta-analyses were performed to estimate pooled prevalence of probable PTSD among healthcare workers in each time period. Subgroup analyses were carried out for year, profession, quality of study, COVID-19 mortality rates, and income level within the country of study. Screening identified 21 papers comprising 11,838 healthcare workers published in the 3 years preceding the pandemic, and 129 papers reporting on 130,363 healthcare workers during the pandemic. The pooled prevalence estimate of probable PTSD prior to the pandemic was 15.5% (95% CI: 12.3-19.3%) and this significantly increased during the pandemic to 24.8% (95% CI: 22.0-27.8%), peaking early in the pandemic in 2020 before returning to pre-pandemic levels in 2022. During the pandemic, prevalence estimates were significantly higher among nurses and those in countries with high COVID-19 mortality rates, whilst no significant difference was observed between studies conducted in high-income versus low- and middle-income countries. Substantial heterogeneity was observed. The findings of this review suggest that prevalence of PTSD among healthcare workers significantly increased following the COVID-19 outbreak.

A formal conflict-of-interest policy was developed at the onset of the process and applied throughout. Teleconferences and electronic-based discussion among the chairs, co-chairs, methodologists, and subgroup leads as well as within subgroups, served as an integral part of the guideline development process.<br><br>METHODS: New priority topics and recommendations from the prior guideline iteration were used to identify Population, Intervention, Control, and Outcomes (PICO) questions likely to have new or updated evidence. We conducted a systematic review to identify the best available evidence, summarized the evidence, and then assessed the quality of evidence using the Grading of Recommendations, Assessment, Development, and Evaluation approach. We used the evidence-to-decision framework to formulate recommendations as strong or conditional, or as a good practice statement. "In our practice," statements were included when evidence was inconclusive to issue a recommendation but the panel felt that some guidance based on practice patterns may be appropriate.<br><br>RESULTS: The panel provided 61 statements on the management of children with sepsis or septic shock. Overall, five were strong recommendations, 24 were conditional recommendations, and ten were good practice statements. For 22 PICO questions, no recommendations could be made, but, for seven of these, "in our practice" statements were provided. Compared with the 2020 guidelines, 20 recommendations were new, 13 were updated for clarity and/or new evidence, six were reviewed but not changed, and 22 were carried forward based on consensus of the panel that new evidence was not available. Only three recommendations were based on high or moderate certainty of evidence.<br><br>CONCLUSIONS: Updated management guidelines were issued by a panel of international experts for the best care of children with sepsis or septic shock, acknowledging that most aspects of care continue to have relatively low quality of evidence.}, }

The development of broad-spectrum antivirals (BSAs) focuses either on substances acting directly on viral proteins (direct-acting antivirals [DAA]) or on substances directed at the cell's own proteins (host-targeting antivirals [HTA]). Decades of development have led to the market entry of a number of DAAs with a wide range of antiviral activities; however, their clinical approval has been obtained for individual infections. HTAs have a number of advantages over DAAs, such as a wider range of antiviral activities and a high genetic barrier to viral resistance, which is undoubtedly important when preparing for a battle with an unknown pathogen. The COVID-19 pandemic has allowed for multiple clinical trials for repurposed HTAs, previously licensed for the treatment of other diseases, including cancer. Despite the enormous work done, the arsenal of BSAs capable of protecting against future pandemics caused by pathogen X is very limited. In this review, we described data on the most studied DAAs and HTAs, effective against at least two unrelated viral pathogens, focusing on those that have been studied in late preclinical and clinical trials.

The principal challenge is no longer the absence of treatment options but the limited capacity of traditional care models to deliver guidelinedirected medical therapy (GDMT) consistently and at scale. The COVID-19 pandemic exposed the fragility of hospital-centered HF care, highlighting the need for more resilient, patient-centered management strategies. Remote monitoring (RM) has been proposed as a solution, yet its clinical impact has been inconsistent due to fragmented data streams, declining patient adherence, and heavy reliance on continuous human oversight. Artificial intelligence (AI) offers an opportunity to address these limitations by integrating multidimensional clinical data, enabling earlier detection of deterioration, supporting adherence, and prioritizing clinically meaningful interventions. Emerging evidence suggests that AI-assisted workflows can accelerate GDMT optimization and improve surrogate and clinical outcomes when implemented within supervised care pathways. This has led to the concept of next-generation remote monitoring (NGRM), in which AI analyzes longitudinal physiological and behavioral signals to generate context-aware alerts and actionable recommendations while reducing clinical workload. Successful implementation, however, requires rigorous validation, clear governance, integration with clinical workflows, and safeguards for safety, equity, and accountability. When embedded within structured HF care pathways, AI-enabled monitoring may help bridge the persistent gap between evidence and real-world implementation.}, }

Abnormal G6PD activity (deficiency or overexpression) is closely associated with the pathogenesis of immune-related diseases: G6PD deficiency increases susceptibility to autoimmune diseases (e.g., rheumatoid arthritis, systemic lupus erythematosus) and infectious diseases (e.g., hepatitis, malaria, COVID-19) by inducing oxidative stress and immune cell dysfunction; in tumor immunity, G6PD dualistically promotes tumor cell proliferation while regulating anti-tumor immunity via modulating cytoxic D8[+] T cell exhaustion and macrophage polarization. Additionally, G6PD-targeted immunotherapies, including small-molecule inhibitors and gene therapy, have shown promising preclinical potential for treating immune-related diseases. These findings highlight G6PD as a key metabolic-immune hub, providing critical theoretical basis for understanding immune regulation mechanisms and developing novel diagnostic and therapeutic strategies for autoimmune diseases, infectious diseases, and tumors.}, }

Beyond the direct effects of the viral infection, one of the most significant and concerning issues to emerge is the exacerbated threat of antimicrobial resistance (AMR) by the indirect impacts of COVID-19. Early in the pandemic, widespread empirical antibiotic prescribing occurred despite low bacterial co-infection rates. In addition, azithromycin, whose antiviral effect remains unproven, was frequently used. This high, often unnecessary consumption, coupled with disrupted antimicrobial stewardship (AMS) and infection prevention and control (IPC) programs, created conditions favoring the emergence and spread of AMR. In patients with severe COVID-19, multidrug-resistant organisms were frequently implicated in secondary infections, particularly in intensive care units (ICUs). Nevertheless, previous studies analyzing AMR metrics before and during the COVID-19 pandemic have shown inconsistent results. Strategies to mitigate the COVID-19 pandemic, such as enhanced surveillance, social distancing resulting in lower respiratory infections, and strengthened IPC and targeted AMS interventions, could play protective roles to inhibit the development of AMR. Additionally, targeted interventions-such as prospective audit and feedback, biomarker-guided antibiotic discontinuation, diagnostic stewardship using a rapid molecular test to distinguish viral from bacterial infections, embedding AMS decision support into electronic medical records, and tailoring interventions to high-risk settings such as ICUs-demonstrated the feasibility of reducing unnecessary antimicrobial use (AMU) even during crisis conditions. Also, vaccination against SARS-CoV-2 may indirectly reduce AMU and AMR by lowering the incidence of severe disease and secondary bacterial infections. Future COVID-19-specific AMS frameworks must integrate these experiences during the pandemic. This review synthesizes current evidence on the interplay between COVID-19, AMR, and AMU, and outlines stewardship strategies to reduce AMR in COVID-19 management.}, }

This review encompasses the Korea Disease Control and Prevention Agency COVID-19 response white paper, National Medical Center response report, Ministry of Education and Seoul Metropolitan Office of Education white papers, focusing on pediatric data and policies. Key findings were supplemented with international studies on pediatric COVID-19 epidemiology, vaccination, and educational impacts. Children in Korea accounted for a substantial number of COVID-19 cases during omicron wave, yet severe outcomes remained rare. Surveillance adaptations included dedicated monitoring of pediatric multisystem inflammatory syndrome through antibody testing. The healthcare system rapidly adjusted to pediatric needs by allowing home isolation for mild cases and by permitting caregiver accompaniment during pediatric hospital isolation. Vaccine rollout for adolescents began in 2021 and for ages 5-11 in 2022, with an initial policy focusing on high-risk children and voluntary uptake for others. In the education sector, Korea implemented remote learning infrastructure, distributing devices and expanding internet access to bridge the digital divide. Korea's pandemic response illustrates the importance of pediatric-specific strategies: surveillance, child-friendly healthcare protocols, risk communication to improve vaccine acceptance, and treating schools and child services as essential infrastructure.}, }

This review summarizes evidence from nationwide registries, cohort studies, and clinical trials in Korea, alongside global findings, to describe the epidemiology, risk factors, therapeutic interventions, and prognostic models for severe COVID-19. Between January 2020 and August 2023, Korea reported more than 34 million confirmed cases, with 38,112 classified as severe and 35,608 deaths, yielding one of the lowest case fatality rates among member countries comprising the Organisation for Economic Co-operation and Development. Severity was strongly associated with advanced age and comorbidities such as cardiovascular disease, diabetes mellitus, cancer, psychiatric disorders, and immunocompromised states, including solid organ transplantation and hematologic malignancies. Other risk modifiers included obesity, chronic kidney disease, asthma, and prolonged glucocorticoid therapy. Protective factors included vaccination, regular physical activity, and, in some studies, specific pharmacologic agents. The effectiveness of vaccines was consistently demonstrated, with booster doses markedly reducing hospitalization and mortality, including in high-risk groups such as pregnant women, patients with cancer, and transplant recipients. Antiviral therapies, notably nirmatrelvir/ritonavir and molnupiravir, significantly reduced severe outcomes, while immunomodulators such as dexamethasone and tocilizumab improved recovery in patients with severe disease. Advanced interventions, including extracorporeal membrane oxygenation and lung transplantation, were used for refractory respiratory failure, with favorable survival observed in selected patients. Prognostic models integrating clinical, radiological, and machine learning approaches have been developed to predict disease progression, supporting early risk stratification and resource allocation. The rapid generation of evidence on predicting, preventing, and treating severe disease is a critical element of pandemic preparedness.

Korea's early, coordinated response was associated with low mortality and maintained essential services, yet the prolonged pandemic exposed structural inequalities, workforce strain, and psychosocial impacts. To comprehensively understand these multidimensional effects, this review synthesizes systematic and narrative evidence on the clinical, epidemiologic, and societal consequences of COVID-19 in Korea. We conducted a combined systematic and narrative review of Korean evidence (2020-2025). The systematic review included studies from PubMed, Embase, KoreaMed, and KMbase, supplemented by manual journal searches. Eligible studies addressed key epidemiologic indicators, including seroprevalence, mortality among patients with comorbidities, severe outcomes in high-risk groups, and vaccination coverage by comorbidity. Quality was assessed using Joanna Briggs Institute tools. We additionally examined government white papers, national reports, policy briefs, and peer-reviewed articles to contextualize epidemiologic findings, synthesizing materials across health burden, healthcare system changes, social consequences, and policy responses. Twenty-four epidemiologic studies and 72 narrative sources were included. Seroprevalence remained below 1% during the early pandemic, increasing sharply after omicron's emergence. Patients with chronic illnesses consistently experienced higher risks of severe outcomes and mortality, while high-risk groups showed elevated odds of intensive care use and complications. Alongside clinical patterns, national data documented substantial reductions in outpatient visits, elective procedures, emergency care, and pediatric services. Burnout and psychological distress intensified among healthcare workers, while prolonged distancing and economic disruption contributed to widening social fatigue. Policy responses and vaccination improved population outcomes, although gaps persisted in communication strategies and addressing disparities across age, socioeconomic status, and comorbidity groups. Korea's experience underscores that preparedness must align clinical efficiency with social equity. Strengthening primary and emergency care, ensuring fair compensation and workforce protection, and maintaining transparent risk communication are essential for building a resilient, inclusive public health system to withstand future pandemics.}, }

During the 2024-2025 season, two mRNA vaccines (Pfizer-BioNTech and Moderna) and one recombinant protein vaccine (Novavax) targeting JN.1 lineage were administered primarily to high-risk groups. Beginning in October 2025, two mRNA vaccines (Pfizer-BioNTech and Moderna) adapted to LP.8.1 variant have been introduced as the updated 2025-2026 season formulations.

We summarize the mechanisms that generate CSD, indicators that can be extracted from surveillance data, and the conditions under which signals may be detectable. We then examine case studies to illustrate the opportunities and challenges of applying EWS to VPD resurgence. Theory and computer simulations show that CSD can precede both elimination and resurgence, with increases in variance and autocorrelation calculated from disease surveillance reports emerging as consistent indicators. Empirical evidence supports this potential, though performance depends on noise structure, seasonality, spatial clustering, and outbreak responses. Case studies highlight both successful applications and contexts where signals were weak or absent. EWS offer a promising framework for anticipating VPD resurgence, but further research is required to refine methods, integrate mechanistic and social-behavioral drivers, and evaluate applicability across pathogens and settings.}, }

Slovakia, a central European country with a population of 5.4 million, continues to face significant health and health care system challenges. Slovakia's health system is founded on universal coverage with compulsory health insurance, a broad benefits package and a competitive insurance model. Although life expectancy improved between 2000 and 2019, the COVID-19 pandemic reversed gains, and in 2023 Slovak life expectancy remained three years below the European Union (EU) average. Circulatory diseases and cancer are the leading causes of death, and noncommunicable diseases such as diabetes and mental illness are rising. Nearly one third of all mortality is linked to behavioural risk factors, including poor diet, high smoking rates, low physical activity and obesity. Slovakia's health care system features competition among three insurers - one state-owned (Všeobecná zdravotná poisťovňa, VšZP) and two private. Since major reforms in 2004, the system has decentralized responsibilities and adopted selective contracting to enhance efficiency. However, structural weaknesses remain, particularly in financial sustainability, accessibility and equity. Health spending from public sources was 8.3% of gross domestic product (GDP) in 2024, yet out-of-pocket (OOP) payments account for nearly 19% of expenditures, disproportionately burdening low-income households. Workforce shortages, especially in nursing and primary care, are worsened by emigration and an ageing staff. Urban-rural disparities persist, with modern infrastructure and specialized services concentrated in cities. Digital health advancements, such as the National Health Information System (NHIS), aim to modernize care and facilitate telemedicine, though implementation is uneven. Ongoing reforms target cost containment, infrastructure optimization and integration of long-term care (LTC). Key priorities include addressing regional disparities, improving workforce retention, reducing waiting times and enhancing eHealth adoption. Despite universal coverage, Slovakia must address persistent gaps in health outcomes, resource distribution and system resilience to meet the needs of its population.}, }

Abnormally hard outer shells (M) are associated with burrowing animals, e.g., pangolins, and SARS-CoV-2 likely acquired these shells due to its long-term evolutionary interactions with pangolins. As for virulence, the inner shell of SARS-CoV-2 (N) has been found to exhibit lower disorder than that of SARS-CoV-1. This lower disorder is consistent with the fact that SARS-CoV-2 is less virulent than SARS-CoV-1, as higher disorder in the inner shell is associated with more efficient protein-protein binding during replication. The link between N/M disorder and virulence or infectivity falls under the umbrella of shell disorder models (SDMs), which can connect virulence, infectivity, and long COVID under one coherent concept. Evidence of the reliability and reproducibility of SDMs as applied to COVID-19 is examined. The hard M that is resisting the antimicrobial enzymes in the respiratory system can be extended to immunological enzymes, especially those found in phagocytes such as macrophages, which can therefore become a reservoir for the virus.}, }

Although cases of dermatomyositis (DM), particularly anti-MDA5-positive DM, have been increasingly reported after SARS-CoV-2 vaccination, its clinical spectrum and management remain incompletely defined. We conducted a narrative review of the literature on post-vaccination dermatomyositis, focusing on clinical features, autoantibody profiles, therapeutic approaches, and outcomes. The review was enriched by the inclusion of a new case: a 60-year-old woman who developed anti-MDA5-positive dermatomyositis two weeks after receiving her fourth dose of the BNT162b2 (Pfizer/BioNTech) vaccine. She presented predominantly with cutaneous and articular manifestations in the absence of interstitial lung disease. Treatment with oral prednisone, intravenous alprostadil, and the Janus kinase inhibitor tofacitinib resulted in marked clinical improvement. This case, together with the literature review, illustrates both typical and atypical presentations of vaccine-associated anti-MDA5 DM, highlights diagnostic challenges without lung involvement, and suggests JAK inhibition as a potential therapeutic option, contributing to a more comprehensive understanding of post-vaccination dermatomyositis.}, }

This narrative review explores the causes of this gap, highlighting several examples from early development to final implementation. These show that technical validation alone is insufficient. Success depends on alignment with clinical need, robust external validation, patient empowerment and sustainable funding models. Furthermore, other systemic barriers include data privacy concerns and lack of transparency by commercial companies. To improve adoption and translate promise to practice, more international alignment of regulations and international collaboration is needed. Lessons must be learned from promising initiatives that did not reach clinical care, as much as from their successful counterparts. Ultimately, a comprehensive redesign of healthcare will be undertaken, with digital diagnostics and therapeutics both embedded as critical components rather than add-ons. This demands a multi-stakeholder effort involving governments, regulatory bodies, insurance providers, industry, research funders, hospital leadership, clinicians and, most importantly, patients.}, }

The evidence indicates that GM dysbiosis is a significant risk factor for the susceptibility and severity of various respiratory conditions, including asthma, chronic obstructive pulmonary disease (COPD), cystic fibrosis (CF), and infections, such as COVID-19 and pneumonia. Specific microbial signatures and metabolic profiles, particularly involving short-chain fatty acids (SCFAs), are associated with disease states and outcomes.

She initially presented with progressive abdominal pain and fever, with negative early imaging studies. Three weeks later, computed tomography (CT) demonstrated new hepatic abscesses. Interventional radiology drainage cultures initially grew Streptococcus intermedius, guiding targeted antimicrobial therapy; however, the patient clinically deteriorated with recurrent abscess formation despite drainage and broad-spectrum coverage. Subsequent aspirate cultures from the abscess fluid later grew P. megaterium, though this result was finalized after the patient's death on day 12 of admission despite intensive care and source control attempts.

Asthma was suspected, leading to the performance of SPTs, spirometry, and either a bronchodilator test (in case of an obstructive ventilatory impairment) or MBCT (in case of a normal spirometry) as requested in the pulmonologist referral letter. The spirometry results indicated ILFSI, with a low FEV1 (z-score = -1.74, 79%) while FVC (z-score = -0.97, 88%) and the FEV1/FVC ratio (z-score = -1.35) remained normal. According to the 2022-ERS/ATS guidelines, these findings are considered normal spirometry because of the maintained FVC and FEV1/FVC ratio.

Although protease inhibitors have achieved major clinical success, traditional design strategies face challenges, including resistance development, poor oral exposure of early peptidomimetics, and off-target toxicity of highly reactive covalent warheads. Classical approaches, such as peptidomimetics, macrocyclization, and covalent warhead engineering, are discussed alongside contemporary strategies, including allosteric modulation and targeted protease degradation via proteolysis-targeting chimeras (PROTAC) technology. Particular emphasis is placed on how these strategies address key obstacles, such as resistance evolution, selectivity, metabolic stability, and oral bioavailability. Several quantitative case studies have also demonstrated the growing significance of computational tools in contemporary antiviral discovery. For SARS-CoV-2 main protease (Mpro), these workflows were enabled by the rapid availability of high-resolution experimental crystal structures of the target protein. The evolution of a weak fragment (Kd ≈ 1.7 mM; ΔG ≈ -3.6 kcal/mol) into a covalent inhibitor (QUB-00006-Int-07) with enzymatic inhibition (IC50 ≈ 830 nM) was successfully guided by molecular dynamics (MD) simulations and absolute binding free energy calculations. This was subsequently confirmed experimentally using NMR, ESI-MS, and FRET assays. Furthermore, out of 25 computationally prioritized candidates with Ki values less than 4 μM, 15 active Mpro inhibitors were identified using accelerated free-energy perturbation-based repurposing campaigns. Long-range allosteric pathways connecting the catalytic site to resistance-associated regions and experimentally verified allosteric pockets have also been discovered using dynamic nonequilibrium MD. Together, these integrated in silico approaches enable the early prioritization of high-affinity ligands, mechanistic understanding of resistance, and significant reduction of late-stage attrition in antiviral drug discovery. Through detailed case studies on SARS-CoV-2 main protease (Mpro), Zika virus NS2B-NS3 protease, and Dengue virus NS2B-NS3 protease, the review illustrates how medicinal chemistry principles translate molecular insights into clinically relevant antivirals. Finally, a forward-looking development roadmap is proposed that integrates potency, selectivity, pharmacokinetics, manufacturability, and resistance management toward the goal of broad-spectrum, durable, and adaptable protease-targeted therapeutics development.}, }

With the ubiquity of technology in the classroom and the recent COVID-19 pandemic creating accessibility barriers for students, there is a need for viable digital resources to enhance learning by supplementing traditional textbook studying. This article describes the creation of an annotated, interactive, three-dimensional digital model and presents preliminary data on its effectiveness for students learning musculoskeletal structures of the hip and knee for the first time. The 3D model was developed in Blender using open-source files and was uploaded to the Sketchfab platform. Eighty-one students in the musculoskeletal anatomy course at a large midwestern university took an assessment to measure their baseline anatomical knowledge, studied the testable structures from either the model or textbook images for 10 min, and took a follow-up assessment. Students in the 3D Model Group saw greater increases from their baseline scores and also reported higher confidence in what they had learned, increased ability to visualize anatomical structures, and greater enjoyment of their resource than students who used textbook images. The findings presented here suggest that creating effective, accessible 3D digital resources is feasible for educators without training in technology-related fields and that having access to these resources can be beneficial to first-time learners of anatomy.}, }

This systematic review assessed the cost effectiveness and reporting quality of NPI evaluations across both diseases. The study was registered with PROSPERO (CRD42024552613).<br><br>METHODS: Following the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines, we searched five medical (PubMed, Scopus, EMBASE, CINAHL, and EconLit) and four health technology assessment databases (NHS HTA, CRD DARE, NHS EED, and INAHTA) up to December 2025, including only full economic evaluations. The search strategy incorporated four domains-'influenza,' 'COVID-19,' 'NPIs,' and 'economic evaluation'-and was guided by the WHO NPI framework, encompassing five domains: personal protective, environmental, physical distancing, travel-related, and educational measures. Reporting quality was assessed using the Consolidated Health Economic Evaluation Reporting Standards 2022 (CHEERS 2022) checklist.<br><br>RESULTS: Thirty-three studies (13 influenza, 20 COVID-19), predominantly from high-income countries, were included. School closures, the most frequently evaluated NPI, were generally not cost effective except during severe pandemics or bundled with other measures. Workforce and business closures were cost effective only in high-severity influenza, with inconsistent findings for COVID-19. Social distancing was cost effective for COVID-19 but not for H1N1 influenza. Isolation, lockdowns, and travel restrictions were cost effective only when implemented early. Face masks and hand hygiene, assessed solely for COVID-19, were generally cost effective when implemented alongside other measures. The median CHEERS score was 75.0%, with one study rated excellent.<br><br>CONCLUSION: Our review highlights heterogeneity in cost effectiveness by pandemic severity, intervention type, bundling of measures, and timing. Strategies that combined low-cost NPIs like masks or hand hygiene demonstrated better value, while socially disruptive measures like school and business closure incurred high costs with inconsistent cost-effectiveness outcomes. Integration with vaccines or antivirals further enhanced cost effectiveness. Evidence gaps include the scarcity of evaluations from low-resource settings and variability in country-specific value thresholds. Addressing these gaps is essential for guiding efficient and cost-effective pandemic preparedness.}, }

Data from multiple regions, including Moscow, Saint Petersburg, the Siberian Federal District and others, were analyzed to assess species diversity and epidemiological patterns.<br><br>RESULTS: The species spectrum of NTM in Russia is broad and heterogeneous. M. avium is the predominant species with an average frequency of 30-40%. A secondary group, including M. gordonae (13-25%) and M. intracellulare (12-20%), demonstrates significant prevalence. The remaining species, such as M. fortuitum, M. lentiflavum, M. kansasii, and M. abscessus, exhibit lower but notable frequencies ranging from 3% to 20%. Other species such as M. malmoense, M. xenopi, M. simiae etc. were less common, with frequencies below 5%. Regional differences in species prevalence were pronounced, with M. avium-intracellulare complex dominating in many areas reaching more than 50% of all NTM, while species like M. lentiflavum were more common in specific regions such as the Republic of Komi (44% of all NTM in the region). The COVID-19 pandemic (2020-2023) impacted epidemiological surveillance but did not substantially alter species diversity. Advanced molecular techniques, including whole-genome sequencing, revealed subspecies-level diversity, notably among M. avium and M. abscessus complexes.<br><br>CONCLUSIONS: This study underscores the significant geographic variability and species diversity of NTM in the Russian Federation.

Patients with post-infectious respiratory or cardiovascular sequelae present an increased anesthetic risk due to persistent inflammation, pulmonary fibrosis, reduced lung compliance, and myocardial dysfunction. These alterations predispose to hypoxemia, arrhythmias, and hemodynamic instability during surgery, making preoperative assessment and individualized anesthetic planning essential. Comprehensive evaluation, including functional tests, cardiac and pulmonary imaging, and laboratory analysis, allows early identification of residual organ dysfunction that can compromise perioperative safety. Anesthetic management must be adapted to the patient's physiological condition, emphasizing lung-protective ventilation, cautious fluid therapy, and close hemodynamic monitoring. Regional anesthesia is preferred when feasible to minimize airway manipulation and reduce respiratory complications, while total intravenous anesthesia represents a safer option when general anesthesia is required. Postoperative care focuses on extended respiratory monitoring, multimodal analgesia to limit opioid use, and the implementation of pulmonary physiotherapy and antithrombotic prophylaxis to prevent complications. Psychological support is also recommended to address post-COVID anxiety and fatigue, contributing to holistic recovery. Although clinical guidelines provide useful recommendations, current evidence remains limited and heterogeneous. Further research is required to clarify the pathophysiological mechanisms of long COVID, evaluate anesthetic drug interactions, and develop validated risk stratification tools. Establishing standardized, evidence-based perioperative protocols is essential to improve outcomes and ensure patient safety in individuals with long COVID undergoing emergency surgery.}, }

Analysis of multi-year surveillance data across hemispheres reveals that severe acute respiratory syndrome coronavirus-2 exhibits seasonal divergence, with consistent summer surges in tropical regions, such as India, and winter peaks in temperate climates. We propose that this pattern arises primarily from human (host) behavioural responses to multi-animal tropism to climatic (environment) extremes, which recreate high-risk indoor transmission settings under both heat and cold. Unlike influenza, severe acute respiratory syndrome coronavirus-2 (agent) combines thermal resilience, broad tissue tropism, and efficient pre-symptomatic transmission, allowing persistence beyond classical winter bounds.

Although classically bacterial-driven, virus-associated presentations like herpes simplex virus (HSV)-linked phlyctenular disease, pediatric PKC during acute coronavirus disease 2019 (COVID-19) infection, and molluscum contagiosum-driven keratoconjunctivitis suggest the same antigen-mediated pathway. Photophobia and discomfort are prevalent, and corneal involvement can cause neovascularization, scarring, amblyopia, and perforation. This minireview combines epidemiologic, clinical, and immunopathologic data to identify causes and update care. Practical takeaways: (1) Treat the antigen source (blepharitis/rosacea, chlamydia, parasites) and screen for tuberculosis when risk factors exist. Consider viral triggers when history or exam suggest HSV, recent COVID-19, or eyelid molluscum; (2) Suppress inflammation promptly with a short, carefully tapered course of topical corticosteroids; (3) Use topical cyclosporine as a steroid-sparing agent in recurrent or steroid-dependent disease; and (4) Reduce antigen load with lid hygiene and targeted antimicrobials. Start antitubercular treatment for tuberculosis. If a viral cause is anticipated, add antiviral medication or molluscum lesion eradication to the steroid-sparing regimen. Trigger-focused, steroid-sparing treatment reduces recurrences, vision-threatening consequences, and steroid exposure.}, }

A multidisciplinary panel of experts conducted a comprehensive review of the literature, distinguishing between associative evidence from observational studies and causal inferences derived from interventional trials addressing gut barrier integrity, dysbiosis, intestinal cancer prevention, respiratory infections, and autoimmune diseases. While vitamin D deficiency has been consistently associated with alterations in gut microbiota composition, increased intestinal permeability, impaired immune tolerance, and increased susceptibility to infections and autoimmune conditions, evidence from interventional studies remains more variable. Clinical outcomes are influenced by baseline 25(OH)D status, supplementation dose and formulation, timing of intervention, and disease context. Vitamin D supplementation has shown potential benefits in selected settings (i.e., autoimmune diseases and acute respiratory infections), and particularly in cases of documented deficiency. Given its pleiotropic role and favourable safety profile, appropriate screening and optimization of vitamin D represent a low-cost and potentially impactful strategy to support gut barrier function and immune competence. While further research is needed to define these therapeutic applications, maintaining vitamin D concentrations above 20 or 30 ng/mL in individuals at skeletal or immunological risk emerges as a reasonable clinical target.

Evidence on SARS-CoV-2 sublineages, influenza, respiratory syncytial virus, rhinovirus, adenovirus, human metapneumovirus, human parainfluenza virus, human coronaviruses, and cytomegalovirus has been collected and identified. Identified risk factors include demographic characteristics such as pediatrics and older age, male sex, race (Black, Hispanic, American Indian or Alaska native), preterm birth, and HLA-DQA1, IFNAR2, ST6GAL, and B3GALT5 genetic susceptibility. Behavioral, socioeconomic (low socioeconomic status, crowded living conditions), environmental influences (cold seasons, pollution), smoking, obesity and malnutrition could also exacerbate the risk of infection and adverse outcomes. Comorbidities, such as chronic conditions and immunocompromised states, significantly increase the risk of severe disease and hospitalization. Laboratory indices linked to severe disease outcomes include neutrophilia or neutropenia, lymphopenia, eosinopenia, and elevated C-reactive protein. Viral subtypes, viral load kinetics, vaccination status, and antiviral therapies further delineate risk profiles. Epithelial barrier impairment and underlying chronic airway diseases characterized by type 2 immunity also play a detrimental role in the development and severity of respiratory viral infections. Our findings highlight the need for stratified prevention strategies, which combine universal measures targeting shared determinants with virus-specific interventions addressing unique virological and transmission dynamics.

Influenza A virus (IAV), SARS-CoV-2, and respiratory syncytial virus (RSV) use distinct entry receptors, yet severe disease is repeatedly marked by AEC2 dysfunction, alveolar barrier failure, and dysregulated inflammation. We synthesize cross-virus evidence for convergence on a small set of host hubs: innate sensing and interferon signaling, mitochondria-centered immunometabolism and oxidative stress, post-translational signaling modules, barrier and surfactant programs, and regulated cell-death checkpoints. We summarize structural and post-translational mechanisms by which viral proteins disrupt pattern recognition receptor (PRR)-mitochondrial antiviral signaling protein (MAVS) signaling, couple mitochondrial injury to weakened antiviral responses, and bias epithelial fate toward inflammatory lytic injury. Where AEC2-specific evidence is incomplete, especially for integrated PANoptosis-like programs, we label these elements as working models and highlight validation needs. We compare model systems used to study AEC2 infection, including ALI cultures, organoids, lung-on-chip platforms, and single-cell or network analyses. Finally, we discuss host-directed therapeutic opportunities along the cascade, separating near-term approaches from longer-term platform strategies such as targeted protein degradation and targeted nanodelivery, and noting constraints in distal-lung delivery, onset kinetics, and safety. This AEC2-centered convergence framework supports mechanism-driven interpretation of severe viral pneumonia and guides broader-spectrum intervention concepts.}, }

Studies were included if they examined teleworking in adult workplace environments and reported physical, mental, behavioral, or performance-related outcomes. Data from 67 eligible studies (12 from Japan and 55 from other countries) were analyzed for the physical health, mental health, lifestyle factors, and work performance domains. Cultural and institutional factors were examined to understand the regional differences.ResultsTelework has been linked to musculoskeletal discomfort, sedentary behavior, psychological stress, and unhealthy lifestyle choices. Japanese and international studies have identified these challenges, although the manifestations vary by context. In Japan, inflexible teleworking, inadequate home infrastructure, and an office-centric culture exacerbate negative outcomes, particularly for women and caregivers. International studies have highlighted the benefits of flexible scheduling and organizational support. Cultural norms and institutional readiness mediated these effects.ConclusionsThis review demonstrates the need for evidence-based health standards for next-generation remote work environments including avatar-based systems.

A key question in the context of infection and vaccination is whether SARS-CoV-2 exerts direct oncogenic effects or instead acts as a transient immunological stressor capable of reinforcing tumor-permissive pathways. Current evidence does not support classical viral oncogenesis. Rather, severe infection is characterized by early interferon (IFN) imbalance followed by NF-κB-dominant inflammatory amplification, promoting sustained IL-6/JAK-STAT3 and MAPK signaling, chronic cytokine production, metabolic reprogramming, and impaired antitumor immune surveillance. At the molecular level, viral structural proteins modulate host signaling networks. The spike (S1) protein engages TLR2/TLR4-MyD88 pathways, activating NF-κB and MAPK cascades, while the membrane (M) protein reinforces NF-κB-STAT3 circuits linked to epithelial-mesenchymal transition and inflammatory gene expression. These mechanisms intensify pre-existing oncogenic signaling without initiating malignant transformation. Tissue-specific responses are further shaped by IFN competence, renin-angiotensin system balance, and metabolic context. In parallel, immune evasion programs shared by chronic viral infection and cancer, including checkpoint upregulation, impaired antigen presentation, and suppressive myeloid expansion, may be transiently reinforced following severe infection. In contrast, SARS-CoV-2 vaccination induces spatially restricted, self-limited innate activation without sustained inflammatory signaling or persistent antigen exposure. By preventing severe disease and chronic immune dysregulation, vaccination interrupts pathways hypothesized to intersect with cancer biology, with no evidence of increased cancer incidence. Ongoing longitudinal studies are required to clarify the long-term oncologic implications of post-infectious immune remodeling.}, }

While several of these platforms have reached regulatory approval and widespread clinical employment, others remain under evaluation or in various stages of clinical development. These vaccines have significantly reduced infection rates, severe disease, and hospitalizations, particularly among high-risk group.

The lack of pre-existing immunity to the H2 hemagglutinin (HA) facilitated efficient human-to-human transmission, and by the end of the Summer of 1957, most countries around the world reported increasing influenza cases caused by the new influenza virus subtype. The pandemic lasted until 1958, resulting in millions of infections globally, with 1-4 million estimated deaths. The first vaccines targeting specifically the H2N2 subtype were available in autumn 1957, but their limited immunogenicity hampered a successful fight against the "Asian influenza pandemic". After the pandemic, H2N2 became seasonal in the following years. Most individuals developed immunity against both the H2 HA and N2 neuraminidase (NA) proteins of the virus, and vaccines administered in the early 1960s successfully boosted this immunity. In 1968, the circulating H2N2 was replaced by the H3N2 subtype, and individuals with pre-existing N2 immunity were partially cross-protected against severe H3N2 infection, as the two N2 NAs were antigenically similar. Since the disappearance of H2N2 from the human population in 1968, global H2 immunity has been decreasing. This raises concerns about a possible re-emergence of the H2 subtype from animal reservoirs, where the virus has circulated for decades, into the human population. As preparedness for future pandemics, research on H2-specific vaccines is currently ongoing, with several candidates being tested in preclinical studies and early-phase clinical trials. In contrast to 1957, vaccine technology platforms, but also the assays used to assess vaccine immunogenicity, and efficacy, have significantly improved. This review aims to summarize the key historical milestones of the Asian influenza pandemic, the impact of H2N2 immunity during and after the 1957 pandemic, the immunogenicity of H2N2-specific vaccines in both a pandemic and pre-pandemic situation, and H2N2-specific antiviral treatment.}, }

Recent evidence suggests that lifestyle diseases and viral infections further exacerbate OSA severity through common inflammatory and metabolic pathways. Parallelly, gut dysbiosis has gained recognition as a key mediator which links respiratory, metabolic, and infectious disease processes via the gut-lung axis. This review explores the convergent role of gut microbial dysbiosis across OSA, lifestyle-associated comorbidities such as obesity, diabetes, and cardiovascular disease and viral infections including respiratory syncytial virus (RSV), influenza, dengue, Human Immunodeficiency Virus (HIV), and SARS-CoV-2. Across these conditions, a recurring pattern of reduced beneficial commensals (e.g., Bifidobacterium, Faecalibacterium prausnitzii, Roseburia, Akkermansia muciniphila) and a noted increase of pro-inflammatory taxa (e.g., Escherichia, Streptococcus, Enterobacteriaceae) has been observed. It contributes to epithelial barrier breakdown, endotoxemia, metabolic dysfunction, and immune dysregulation. In OSA patients, intermittent hypoxia is observed that causes gut barrier impairment and microbial translocation, thus amplifying systemic inflammation. Similarly, viral infections reshape the gut ecology, bringing adverse effects to host immunity and respiratory outcomes. The review highlights upon the therapeutic potentials of prebiotics and probiotics supplementation for modulating gut dysbiosis. It discusses the role of these therapeutic interventions in improving metabolic homeostasis, reducing inflammation, and potentially mitigating OSA-related complications. Collectively, this analysis highlights gut dysbiosis as a plausible unifying mechanism connecting lifestyle diseases, viral infections, and OSA, presenting a compelling avenue for integrated, microbiome-targeted interventions.}, }

We focused on the perspectives of all interest-holders: facilities, residents, their relatives and nursing home staff.<br><br>METHODS: We searched MEDLINE and CINAHL and included quantitative studies published in English since the beginning of the pandemic (2020 to 2024). The extracted parameters were initially categorised according to five dimensions: pandemic-related data, facility level, staff level, residents and relatives. Within each dimension, the original terms were compared and inductively organised into (sub-)categories based on conceptual similarities, with synonymous terms subsequently standardised.<br><br>RESULTS: From 82 included articles, 96 different parameters related to COVID-19 in nursing homes were identified. Infection and mortality rates emerged as the pandemic-related data most often reported, particularly within this dimension but also across all dimensions.

Despite extensive research, the evidence on nurse retention remains fragmented and frequently focuses on isolated determinants. This review aimed to synthesize the multifactorial determinants of nurse retention by integrating organizational, relational, and individual perspectives. Methods: An integrative review was conducted following Whittemore and Knafl's approach and reported according to PRISMA 2020 guidelines where applicable. A systematic search of six databases identified studies published between 2016 and 2026 addressing nurse retention in hospital settings. Included studies underwent methodological quality appraisal using validated tools, and findings were synthesized narratively. Results: Twenty-five articles were included. The analysis revealed differences in perspective between nurse managers and nurses regarding the factors that influence retention. Transformational and participative leadership among nurse managers enhanced staff retention through supportive organizational climates and higher professional commitment. For staff nurses, positive work environments, collegial support, and psychological resources such as self-efficacy and resilience were key predictors of intention to stay. These findings can be interpreted through Herzberg's Two-Factor Theory, Self-Determination Theory and Theory of Planned Behavior, which collectively highlight how recognition, autonomy, and competence satisfaction drive nurses' intention to remain in their roles. Conclusions: Nurse retention reflects dynamic, multilevel processes rather than the influence of single determinants. Integrated, theory-informed approaches targeting organizational structures, relational climates, and individual psychological resources are required to strengthen workforce sustainability and support high-quality care delivery.}, }

Human metapneumovirus (hMPV) is a globally prevalent pathogen associated with acute lower respiratory tract infections in infants, older adults, and immunocompromised individuals. Avian metapneumovirus (aMPV) imposes substantial economic losses on the poultry industry through respiratory disease, reproductive impairment, and high mortality in the presence of secondary infections. Despite their distinctive host ranges, hMPV and aMPV share a conserved genomic architecture and encode homologous structural and non-structural proteins that mediate viral entry, replication, assembly, and evasion of host innate immunity. Comparative analysis highlights that both have deeply conserved polymerase and nucleocapsid functions, and yet have a wide range of diversity in the attachment glycoprotein (G) and small hydrophobic protein (SH), reflecting divergent evolutionary pressures in human versus avian hosts that have led to such distinctive differences. The recent emergence and detection of aMPV/A and aMPV/B across the previously aMPV-free United States beginning in late 2023, combined with rising cases globally of hMPV post-SARS-CoV-2 pandemic, underscore the continued challenges of metapneumovirus surveillance and control in humans and animals. This review aims to highlight the current knowledge on the history, molecular virology, pathogenesis, epidemiology, diagnostics, and control strategies for aMPV while drawing mechanistic parallels to hMPV. By contextualizing shared biology and structure alongside host-specific adaptations, we aim to identify key gaps that shape vaccine design, antiviral development, and future research priorities aimed at mitigating the health and economic burden posed by metapneumoviruses found in both birds and humans.}, }

Interestingly, TTS was sharply incremented during and following the COVID-19 pandemic. Despite increased clinical recognition, reliable biomarkers for early diagnosis and prognosis remains limited. Oxidative stress is increasingly recognized as a key mechanism in TTS, acting downstream of sympathetic overactivation, thus contributing to myocardial stunning, endothelial dysfunction, and inflammation. In this context, extracellular vesicles (EVs) have emerged as key mediators of intercellular communication and as potential circulating biomarkers, as they reflect the molecular state of their cells of origin. In this review, we summarize the current diagnostic approaches for TTS, including the InterTAK Diagnostic Score, imaging gold standards, and emerging biomarkers such as circulating miRNAs and EV cargo associated with TTS.

Until 30 years ago, PCR product analyses were generally performed after amplification using gel-based methods. Quantification typically relied on visual inspection or densitometry of end-point products and was therefore relatively unreliable and poorly suited to high-throughput automation. To celebrate real-time PCR's 30-year anniversary of commercial availability, Professor Stephen Bustin, Guest Editor for the special edition, "Advancing Molecular Science Through Reproducible qPCR: MIQE Guidelines and Beyond," asked Russell Higuchi to give a historical account on how his idea of real-time PCR was conceived and brought to fruition. Dr. Higuchi then asked his collaborator, Lincoln McBride, who drove the development of the ABI 7700-the high-throughput real-time PCR instrument that gave researchers access to this technology-to co-author this dual memoir. This story is told from the perspectives of the two scientists most directly responsible for making real-time PCR practical and widely accessible. Taking turns, Russell Higuchi describes the conceptual and experimental steps at Cetus and then Roche that led from homogeneous PCR detection to continuous fluorescence monitoring, whilst Lincoln McBride details ABI's parallel efforts to commercialize Russ's invention. Together, they trace how experimental insight, engineering constraints, product development, and commercial decision-making shaped the Applied Biosystems 7700 Sequence Detection System and established real-time PCR as a practical and reliable quantitative technology. Their team's efforts persevered through technological uncertainty and within a complex corporate collaboration. They share key historical documents in their original form. Their accounts show how the 7700 system emerged as the convergence of chemistry, optics, software, and product development. The eventual global reliance on real-time PCR during the COVID-19 pandemic demonstrated, at unprecedented scale, the profound and enduring impact of these early technical and organizational choices.}, }

It has been suggested that the SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) pathway of entrance into the host cell might be assisted by dipeptidyl peptidase-4 (DPP4), leading to inflammation and cytokine storm, with replication into the airways and unfavorable effects in the lungs. Consequently, the goal of this systematic review is to investigate the most recent data on the effect of DPP-4i (dipeptidyl peptidase-4 inhibitor) medications on clinical outcomes, mainly mortality among COVID-19 patients. Methods: By conducting a systematic search using PubMed and the Cochrane library, observational studies were identified to examine the association between DPP-4i medications and clinical outcomes including mortality, intensive care unit and hospital admissions. The methodologies of included studies were assessed utilizing the Newcastle-Ottawa Scale (NOS). Results: A total of nineteen studies were included with sample sizes varying from over 100 patients to 2.8 million and variant follow-up durations from 30 days up to discharge or death. Most of the population across the studies had COVID-19 for the first time, and the majority were hospitalized. Similarly, mortality definition varied among studies with different time points consisting of 30-day mortality, in-hospital mortality, or all-cause mortality. The majority of the studies identified no effect on mortality by DPP-4i, while a considerable proportion revealed beneficial effects; only four studies showed increased mortality. Conclusions: Real-world data from this review suggested a safe use of DPP-4i among COVID-19 patients; however, randomized clinical trials are required to confirm the beneficial outcomes and safe use.}, }

By combining morphological information from conventional B-mode ultrasound with real-time assessment of microvascular perfusion, CEUS can provide functional insights that improve diagnostic accuracy, guide interventions, and support patient surveillance. Methods: This review summarizes the current evidence on the use of CEUS in major pleuropulmonary disorders, including pneumonia, pleural effusion, pulmonary embolism, neoplasms, and COVID-19-related lung injury. The most relevant clinical studies and meta-analyses were analyzed, focusing on CEUS parameters, diagnostic performance, and integration with other imaging techniques. Results: CEUS enables the differentiation between inflammatory, ischemic, and malignant lesions through qualitative and quantitative analyses of enhancement patterns. Early and homogeneous enhancement is typical of inflammatory or infectious processes, whereas heterogeneous or delayed enhancement with early washout strongly suggests malignancy or ischemia. In pneumonia and pleural infections, CEUS identifies non-perfused or necrotic areas, guiding drainage and evaluating therapeutic responses. In pulmonary embolism, it reveals avascular consolidations corresponding to infarction, even when CT angiography is inconclusive. For peripheral lung tumors, CEUS assesses angiogenesis and vascular supply, correlating perfusion parameters with histopathology, and improving biopsy targeting. Furthermore, in COVID-19 pneumonia, CEUS can detect microvascular alterations related to thrombosis and fibrosis. Conclusions: CEUS is a safe, noninvasive, and radiation-free technique that provides unique real-time information on pulmonary perfusion. Its integration with conventional ultrasound enhances diagnostic precision, optimizes interventional guidance, and allows for dynamic monitoring of treatment response. Future developments in quantitative analysis, artificial intelligence, and targeted contrast agents are expected to further expand CEUS clinical applications in pleuropulmonary imaging.}, }

The thyroid gland is also susceptible, as it contains ACE2 receptors, making it exposed to both direct viral damage and autoimmune-mediated dysfunction. Recent reports document the various thyroid complications that persist well after the acute infection phase. This systematic review investigates the long-term thyroid complications in individuals with a history of SARS-CoV-2 infection. A comprehensive literature search across several databases was conducted. Eligible studies reported new onset long-term thyroid complications occurring post-COVID-19 infection. Abstract and full-text screening as well as data extraction and quality assessment was performed by two independent reviewers. Only 28 studies met our inclusion criteria, reporting 419 patients from 18 countries. These studies included case reports, case series, cohort, and cross-sectional studies. Reported thyroid disorders included subacute thyroiditis, thyrotoxicosis, hyperthyroidism (including Graves' disease), isolated high T3/T4, hypothyroidism, central hypothyroidism, and non-thyroidal illness syndrome (NTIS). While many of these eventually resolved, a significant portion persisted or recurred, especially autoimmune thyroiditis. COVID-19 is associated with a range of long-term thyroid complications. Although some cases are temporary, others last, especially autoimmune thyroid disorders. Proposed mechanisms include direct viral cytotoxicity, cytokine-mediated Hypothalamic-Pituitary-Thyroid (HPT) axis suppression, post-viral autoimmunity, vascular injury, and neuroendocrine disruption. Routine thyroid function monitoring in COVID-19 survivors, particularly those with severe disease or persistent symptoms is recommended, and larger prospective studies are needed to better understand incidence and outcomes.}, }

This review presents recent data on ARI etiology, clinical burden, and antimicrobial resistance (AMR) from Ghana, spanning the pre-COVID-19 era (2010-2019) to the post-pandemic period (2020-2025). Before the COVID-19 pandemic, viral infections, such as respiratory syncytial virus (RSV), rhinoviruses, and influenza viruses, were the major contributors, along with established bacterial pathogens such as Streptococcus pneumoniae and Haemophilus influenzae. Social determinants, including undernutrition and indoor air pollution, also influenced these infections. In the COVID era, we have seen dramatic shifts in pathogen seasonality, the scaling of oxygen delivery systems, and the implementation of genomic surveillance for SARS-CoV-2, as well as new features such as maternal RSV vaccination and monoclonal antibody therapy. Despite its successes in vaccination coverage and health system strengthening, some challenges remain, including fluctuations in implementation and surveillance issues. The simultaneous challenges of pneumonia and hygiene will require integrated, coordinated, multisectoral responses that incorporate surveillance with antibiotic stewardship, sustainable oxygen systems, and interventions for nutrition and environmental health. The review also highlights research priorities and makes policy recommendations well aligned to support national ARI control efforts aimed at reducing child mortality due to ARI and achieving Sustainable Development Goals targets on child health.}, }

This review outlines the numerous intricate considerations involved in establishing suitable assay protocols. Commonly employed M[pro] substrates that exploit different mechanisms for the optical detection of the cleavage reaction are introduced and compared with respect to their suitability for specific assay applications. The contribution of native or tagged forms of M[pro] and of the assay medium to representative kinetic data is debated.

Chest computed tomography (CT) revealed progression of patchy opacities and consolidation in the right upper and middle lobes compared with prior imaging. Next-generation sequencing (NGS) of bronchoalveolar lavage fluid (BALF) detected Aspergillus flavus. Case 2: An 8-year-old girl with fever for 4 days and cough for 2 days was admitted. After admission, recurrent fever occurred; hemophagocytic syndrome and coronavirus disease 2019 (COVID-19)-related multisystem inflammatory syndrome were diagnosed. Sputum culture results were positive for A. fumigatus. Chest CT demonstrated atelectasis of the right upper lobe and left lower lobe. NGS of BALF also detected A. fumigatus. Case 3: A 4-year-old boy was admitted for mesenchymal stem cell infusion. He had undergone bone marrow transplantation 6 months prior to admission. Occasional cough and fever were reported. Chest CT indicated infectious lesions in both lungs. NGS detected A. fumigatus. Bronchoscopy in all 3 children revealed necrotizing tracheobronchitis.

To assess the current state of MDTs targeting stress, anxiety, and depression in adults, we conducted a scoping review using a modified Population, Intervention, Comparison, Outcome (PICO) keyword framework to structure Google search results. Twenty-two commercially available MDTs were identified for inclusion. We organize these MDTs into five principal categories based on underlying treatment strategies: (1) Preference-based music selection; (2) Affective Parameterization; (3) Affect Matching and Compensation; (4) Neural Entrainment; and (5) Biofeedback. We review general evidence supporting each strategy from music neuroscience and therapy research, as well as limited applied research testing specific MDTs. We conclude that, while general evidence supporting musical-based interventions for stress, anxiety, and depression is substantial, evidence for MDTs specifically is presently too limited to draw conclusions about real world effectiveness. Determining whether MDTs are likely to fulfill their potential will require increased focus on rigorous laboratory studies testing specific treatment strategies and randomized double-blind placebo-controlled trials conducted in ecologically valid settings. To support progress in this field, we make recommendations to support the sustainable development of MDTs as evidence-based tools to support mental health and wellbeing.}, }

Blue light exposure from screens disrupts circadian rhythms by suppressing melatonin production, which can worsen sleep disturbances and potentially increase seizure frequency. This review aims to examine the relationships among technology use, sleep disturbances, and seizure control in paediatric patients with epilepsy.<br><br>VIEWS: We conducted a literature review of peer-reviewed studies from databases such as PubMed. The search terms included "blue-light exposure," "screen time," "sleep disturbances," and "epilepsy in children." Studies addressing the effects of blue light, screen time, and digital devices on sleep and seizure control in children with epilepsy were included. Data on sleep quality, seizure frequency, melatonin levels, and the use of mobile applications for sleep and seizure monitoring were analysed. Prolonged screen time was consistently linked to delayed sleep onset, reduced sleep duration, and poorer sleep quality, which may worsen seizure frequency. Children with epilepsy, especially those with photosensitivity, appear particularly susceptible to blue light's adverse effects. Some studies noted reduced melatonin and increased seizure activity following blue light exposure. The review also found growing interest in mobile apps and wearable devices for tracking sleep and seizures, though many tools lack validation.<br><br>CONCLUSIONS: Excessive screen time and exposure to blue light negatively affect sleep and seizure control in children with epilepsy.

This chapter begins by outlining fundamental aspects of virus adsorption and imaging, highlighting, among other factors, the influence of tip-convolution artifacts. These principles are applied to reveal the adsorption behavior of the TGEV coronavirus on surfaces. Subsequent sections detail approaches for probing TMV's mechanical properties through single-indentation experiments and mechanical fatigue protocols. In this section, the mechanical fatigue approach is also discussed when used on 2D arrays of viral coat proteins. The review also discusses how these mechanical techniques can trigger genome release in minute virus of mice (MVM), a process that can alternatively be induced by temperature, as happens in bacteriophage T7. Finally, the chapter illustrates how AFM can serve as a nanomanipulation tool to move individual viruses across surfaces and estimate their adhesion strength.}, }

We estimated meningitis mortality using the Cause of Death Ensemble model (CODEm) and morbidity using DisMod-MR 2.1, incorporating data from vital registration, verbal autopsy, surveillance, hospital data, and systematic reviews. Aetiology-specific estimates were generated with pathogen-linked case-fatality ratios and splined binomial regression models. Risk factor attribution was based on established risk-outcome pairs and population attributable fractions.<br><br>FINDINGS: In 2023, there were 259&#x2009;000 (95% uncertainty interval 202&#x2009;000-335&#x2009;000) global deaths and 2&#xb7;54 million (2&#xb7;20-2&#xb7;93) incident cases of meningitis. Children younger than 5 years accounted for more than a third of deaths (86&#x2009;600 [53&#x2009;300-149&#x2009;000]). Streptococcus pneumoniae, Neisseria meningitidis, non-polio enteroviruses, and other viruses were the leading causes of death, while non-polio enteroviruses caused the most cases. The four WHO-defined preventable meningitis pathogens of interest (S pneumoniae, N meningitidis, Haemophilus influenzae, and Group B streptococcus) contributed to 98&#x2009;700 deaths (77&#x2009;000-127&#x2009;000) and 594&#x2009;000 cases (514&#x2009;000-686&#x2009;000). Low birthweight, short gestation, and household air pollution were the top risk factors for meningitis-related mortality.<br><br>INTERPRETATION: Although mortality and incidence have declined significantly since 1990, progress is insufficient to meet WHO 2030 targets. Despite marked progress in reducing bacterial meningitis via global vaccination campaigns, a substantial meningitis burden persists, attributable both to common pathogens such as S pneumoniae and N meningitidis and to emerging non-bacterial pathogens such as Candida spp and drug-resistant fungi. Achieving WHO goals will require sustained investment in surveillance, vaccination, maternal screening, and health-system strengthening, especially in high-burden settings.<br><br>FUNDING: Gates Foundation, Wellcome Trust, and UK Department of Health and Social Care.}, }

With the onset of the COVID-19 pandemic, the utilization of TD expanded significantly, offering a viable alternative to face-to-face (F2F) consultations, particularly in settings where access to dermatologists are limited.<br><br>OBJECTIVES: This systematic review aimed to evaluate the effectiveness of TD across three key domains: clinical outcomes, patient satisfaction, and cost-effectiveness.<br><br>METHODS: A systematic search was conducted across MEDLINE, Embase, and Web of Science for studies published between 2010 and July 2024. Studies comparing TD with in-person consultations in terms of diagnostic accuracy, patient satisfaction, and cost-effectiveness were included. The quality of the included studies were as assessed using the Newcastle-Ottawa Scale (NOS).<br><br>RESULTS: From 2,768 articles, 23 studies met the inclusion criteria. Clinical outcomes indicated moderate agreement between TD and F2F consultations, with a mean kappa coefficient of 0.57, reflecting diagnostic concordance. Patient satisfaction varied widely, with 26.57% of patients willing to replace F2F consultations with TD. TD was associated with significant cost savings, averaging US$81.31 per patient, with percentage savings ranging from 6.27% to 45.33%, depending on the healthcare system.<br><br>CONCLUSIONS: TD provides moderate diagnostic accuracy, substantial cost savings, and varying degrees of patient acceptance. However, successful implementation requires high-quality imaging, clinician training, and robust technical infrastructure. Further research is needed to optimize TD's role in dermatology, particularly in balancing virtual and F2F care.}, }

Its broad viral attachment capacity arises from structural heterogeneity in sulfation patterns. This review examines HS interactions in enterovirus A71 (EV-A71), severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and chikungunya virus (CHIKV), emphasizing shared features and virus-specific distinctions. HS mediates viral attachment in all three, and additionally promotes SARS-CoV-2 internalization when host receptor angiotensin-converting enzyme 2 is absent. Positively charged residues on the virion dictate HS affinity. High HS affinity enhances in vitro infectivity and plaque size in EV-A71 and SARS-CoV-2, though evidence for CHIKV remains inconclusive. In vivo, elevated HS affinity is associated with viral attenuation and diminished inflammatory responses for both EV-A71 and CHIKV; in EV-A71 specifically, increased HS affinity further correlates with reduced capsid stability and heightened sensitivity to neutralizing antibodies. HS mimetics targeting viral-HS interactions represent promising broad-spectrum antivirals, particularly those advancing in clinical trials.}, }

Among the first approved agents was remdesivir, an injectable nucleoside analogue developed by Gilead Sciences, that led to chain termination of viral RNA synthesis and showed broad antiviral activity against RNA viruses. Early clinical results were mixed: The US ACTT-1 trial reported an accelerated recovery and reduced mortality in treated patients, while the WHO Solidarity and a European trial revealed no impact of remdesivir on mortality. In contrast, a US trial in outpatients demonstrated a clear clinical benefit when treatment was administered early. Molnupiravir, an orally applicable nucleoside analogue developed by Merck, induces lethal mutations in the viral genome rather than chain termination. Molnupiravir showed in vivo antiviral activity against coronaviruses in different animals. In MOVe-OUT trials, molnupiravir reduced the rate of hospitalisation in treated outpatients. In the PANORAMIC trial, molnupiravir reduced the time to recovery in outpatients but not their rate of hospitalisation. No drug effect of molnupiravir was seen in the RECOVERY trial with hospitalised COVID-19 patients. Using structural biology and medicinal chemistry approaches, Pfizer developed nirmatrelvir, an oral inhibitor of the major coronavirus protease. In high-risk but not in standard-risk COVID-19 patients, the combination nirmatrelvir/ritonavir reduced the rate of hospitalisation (EPIC HR and SR trials). Retrospective cohort studies showed treatment effects in defined patient groups. This review compares the efficacy and clinical performance of different antivirals, including emerging drugs such as obeldesivir and alternative protease inhibitors (lopinavir, simnotrelvir). It further examines their roles in prophylaxis, treatment of long covid symptoms, pharmacological considerations and antiviral resistance. Particular attention is given to factors underlying variable outcome of the trials, including viral variant evolution, population immunity increases, disease severity changes and timing of therapy initiation.}, }

The formidable pathogenicity of GAS is fueled by metabolic plasticity that coordinates virulence with niche-specific adaptation. In this minireview, we dissect how GAS functions as a sophisticated metabolic decision-maker, revealing survival strategies of the bacteria that allow persistence and vulnerabilities that can be targeted for therapeutic development. From the oropharynx to the bloodstream, niche-specific carbon sources and availability dictate downstream biosynthetic processes, creating an integrated metabolic network that controls pathogen fitness. Dynamic shifts in central carbon metabolism are orchestrated by an expanded repertoire of global regulators that directly couple nutrient availability to virulence factor expression. The resulting bacterial metabolic byproducts serve as dual-purpose weapons, limiting competition with commensal microbes and reprogramming host cell immune responses. The ability of GAS to fine-tune and couple metabolism to niche-specific survival factors reveals pathogen-specific targets that can be exploited for therapy. We evaluate high-potential therapeutic strategies that aim to disrupt this critical metabolism-virulence nexus. The development of these precision anti-virulence strategies to counter GAS infections is critical in an era of rising antimicrobial resistance.}, }

Understanding effective CT strategies could help governments and health authorities prepare effectively for emergency epidemic or pandemic situations.<br><br>OBJECTIVE: This study aims to systematically review the evidence on the effectiveness of CT across infectious diseases with epidemic or pandemic potential. Effectiveness is measured in terms of impacts on disease transmission, health care use, mortality, or unintended consequences.<br><br>METHODS: We searched 6 bibliographic databases (MEDLINE, Embase, Global Health, CINAHL Ultimate, Cochrane, and Scopus) between November 29 and December 3, 2024, with supplementary citation searching. We sought human studies comparing CT with interventions with no CT or other forms of CT, delivered in the community, in prespecified diseases of epidemic or pandemic potential. We included studies with any measure of disease transmission, related health care use, or unintended consequences of CT and prioritized studies with concurrent comparators. Screening, data extraction, and critical appraisal were performed in duplicate. Due to substantial heterogeneity, a narrative synthesis was performed. This review was informed by meetings with a patient and public involvement and engagement group.<br><br>RESULTS: After deduplication, a total of 12,816 titles and abstracts were screened, with 198 records assessed for eligibility at full text. Five additional studies were found through supplementary searching. Finally, 88 reports (of 86 studies) were included, of which 57 reports (of 55 studies) were prioritized. Two main routes of transmission were represented: respiratory (tuberculosis [TB], 15 studies; COVID-19, 5 studies) and blood-borne or sexually transmitted infections (STIs; 35 studies, of which 13 were in HIV, and 22 were bacterial or parasitic infections). No evidence was found on vector-borne, direct contact, or food- or water-borne routes of transmission. Evidence was highly heterogeneous, and more than half of the studies had notable methodological limitations. While there was no difference between CT and comparator interventions for most outcomes, there was some evidence of reductions in disease prevalence in TB and for provider-initiated CT to be superior to patient-led approaches in STIs. Only 2 studies reported measures of unintended consequences.<br><br>CONCLUSIONS: We found inconsistent evidence for the effectiveness of CT, focused primarily on TB and on contrasts between provider-initiated CT and patient-led referral in STIs and HIV. High heterogeneity in study design precluded clear assertions regarding optimal strategies for CT, including with respect to relevant subgroups. Future work should consider generalizability of CT mechanisms across contexts, including by route of transmission and from the Global South, and a more thorough account of unintended consequences.}, }

This review comprehensively examines the structural characteristics, enzymatic functions, and regulatory mechanisms of CMPK2, emphasizing its significance in maintaining mitochondrial DNA (mtDNA) integrity and energy metabolism. We explore how CMPK2 links mitochondrial stress to inflammation through its involvement in key immune signaling pathways, including the NLRP3 inflammasome and cGAS-STING pathway, thereby modulating innate immune responses. Notably, CMPK2 is upregulated during viral infections, such as SARS-CoV-2 and Zika virus, where it restricts virus replication and enhance antiviral defenses. Furthermore, we discuss the implications of CMPK2 dysregulation in various non-communicable diseases, including systemic lupus erythematosus and neuroblastoma, highlighting its potential as a diagnostic biomarker and candidate therapeutic target. By integrating recent advances in our understanding of CMPK2's roles across infectious and non-infectious diseases, this review establishes CMPK2 as a pivotal node connecting mitochondrial metabolism, immune responses, and disease mechanisms.

Eligible studies were observational and survey-based, reporting prevalence or determinants of individual-level exposure to health misinformation encountered on social media. Exposure was operationalized as (i) perceived exposure (self-reported encountering of misinformation) or (ii) item-level encounter/recognition of predefined misinformation claims framed as prior exposure. Constructs reflecting belief, attitudinal agreement, susceptibility, or behavioral responses were excluded from prevalence pooling to prevent conceptual conflation. Interventional or experimental correction studies were excluded to preserve comparability with naturalistic observational exposure measures. Random-effects meta-analyses were conducted in R (meta/metafor), with heterogeneity quantified using I&#xb2;.

Reported prevalence estimates varied substantially (10%&#x2013;87%) across domains and exposure operationalizations. The pooled prevalence was 59.0% (95% CI: 44.0&#x2013;73.0); however, heterogeneity was extreme (I&#xb2; = 99.8%). Accordingly, the pooled estimate is interpreted as a descriptive contextual summary rather than a generalizable population parameter. Subgroup analyses suggested domain-dependent patterns, with comparatively higher reported exposure in COVID-19 and oral health contexts and lower levels in cancer-related contexts. Across studies, younger age, lower health or digital literacy, and minority ethnicity were recurrently associated with higher reported exposure. Platform-related associations were context-dependent and varied by outcome construct and health domain, indicating that platform effects operate as environmental modifiers rather than intrinsic determinants.<br><br>CONCLUSIONS: Exposure to health misinformation on social media appears common but highly variable across health domains, operational definitions, and platform environments. Given extreme between-study heterogeneity, reliance on cross-sectional self-reported measures, and variability in exposure operationalization, findings should be interpreted as contextual rather than universally generalizable.

This report analyzes the Saudi Arabian experience as a successful hybrid resilience model that synthesized centralized government authority with decentralized private sector agility. Centrally, the National Unified Procurement Company (NUPCO) utilized unified purchasing power to secure international deals, while the Saudi Food and Drug Authority (SFDA) provided regulatory agility by fast-tracking imports and registrations. Complementing this, major private distributors like Al Nahdi Medical Company reported digital logistics investments enabling distribution efficiency.

Similarities between post-COVID and post-infectious Irritable Bowel Syndrome (PI-IBS) suggest that the latter can serve as a useful model for understanding pathophysiological mechanisms and developing therapeutic approaches. Both conditions are functional disorders triggered by an acute infection, with multifactorial etiology and limited biomarker-based diagnostics. The variability of symptoms and the high frequency of comorbidities make these disorders particularly difficult to diagnose. Diagnostic efforts may be further hindered by the stigmatization of such disorders among healthcare providers, the health insurance industry, and the general public. This article explores the parallels between PI-IBS and post-COVID, highlighting, on the one hand, what can be learned from the management of IBS to better address the needs of patients with post-COVID long-term sequelae, and, on the other hand, raising doubts-based on decades of research into drug therapy development for IBS-about the likelihood of a rapidly available treatment for post-COVID.}, }

Since 2023, its high prevalence coupled with rising rates of macrolide resistance has presented substantial challenges in the clinical management of pediatric MP infections. In light of the impact of the COVID-19 pandemic on the epidemiology of respiratory pathogens, this article reviews relevant global studies conducted before, during, and after the pandemic. A comprehensive narrative review approach was adopted, with literature searches conducted in databases including PubMed and Web of Science up to December 2025.The findings reveal notable shifts in the epidemiology of MP in the post-pandemic period: the epidemic season has lengthened with a displaced peak, the proportion of cases among school-aged children has risen, and the incidence of severe Mycoplasma pneumoniae pneumonia (SMPP) has increased. Globally, macrolide-resistant Mycoplasma pneumoniae (MRMP) rates continue to climb, remaining especially high in East Asia (>80%), and are closely linked to specific genotypes such as P1-1 and M4572. Disease severity is associated with both host-derived exaggerated inflammatory responses (e.g., elevated IL-6 and LDH) and the virulence activity of the CARDS toxin. The profile of co-infections has also undergone change. In summary, against a background of reduced pathogen exposure and the formation of immune intervals and high antimicrobial resistance, the COVID-19 pandemic has compounded the clinical complexity of managing MP infections. Future efforts should prioritize enhanced global surveillance, the development of rapid diagnostics and novel therapeutics, and the optimization of antibiotic stewardship strategies.}, }

This scoping review aims to systematically examine the existing literature to explore the mechanisms contributing to the development of CMBs in ARDS and to summarize current evidence on CMBs associated with severe respiratory failure. We conducted a comprehensive search across two databases, PubMed and CENTRAL, and relevant study registries (PROSPERO and Clinicaltrials.gov), between February 1 and March 3, 2025. Eligible studies included those reporting on the presence of CMBs in adult patients with severe respiratory failure or ARDS, regardless of whether mechanical ventilation (MV) was used. Eighteen observational studies involving critically ill patients with respiratory failure or ARDS were included, with sample sizes ranging from 9 to 214 patients. The proposed pathophysiological mechanisms for the development of CMBs include hypoxaemia and inflammation leading to endothelial injury and blood-brain barrier (BBB) dysfunction, cerebral hypoperfusion facilitating interaction between coronavirus disease 2019 (COVID-19) and angiotensin-converting enzyme 2 (ACE2) receptors, microangiopathy with the formation of diffuse microthrombi, and renal failure contributing to uraemia-associated BBB disruption. CMBs were predominantly localized in the corpus callosum and juxtacortical white matter. The majority of patients with CMBs were mechanically ventilated and experienced a prolonged duration of ventilation. Identified risk factors for CMBs development included greater disease severity, coagulation abnormalities, and renal dysfunction. In conclusion, CMBs are increasingly recognized in critically ill patients with ARDS, particularly in the corpus callosum and juxtacortical white matter, but current evidence is associative rather than causal. Their pathophysiology likely involves compromised small vessel integrity due to hypoxia-induced endothelial injury, inflammation, and possible direct viral effects on cerebral microvasculature. These mechanisms are further exacerbated by coagulation abnormalities and disruption of the BBB.}, }

While air quality generally improved in early 2020, this was tempered by increased formation of secondary pollutants (e.g., O3 and secondary particulate matter, PM) in many regions studied. Declines in NOx emissions were largely responsible for the changes in O3, driving decreases in O3 concentrations in remote regions and increases in urban regions due to both decreases in O3 titration by NOx and also nonlinear changes in O3 production. Lower NOx levels also increased the levels of other oxidants (e.g., OH and O3), leading to a general increase in atmospheric oxidation in polluted urban regions. This enhanced oxidation promoted additional PM formation in some regions but was generally outweighed by decreases in primary PM and other secondary precursors (SO2 and VOCs). The COVID-19 pandemic gave rise to large local perturbations in air quality but only modest reductions in the global abundance of short-lived climate forcers (including O3 and PM).}, }

They demonstrate remarkable plasticity by transitioning from proinflammatory (M1) and anti-inflammatory/reparative (M2) phenotypes in response to local signals. Upon exposure to environmental agents, such as particulate matter, atypical respiratory pathogens, opportunistic Gram-negative bacteria, or respiratory viruses, they undergo dynamic activation that profoundly influences their functional repertoire. Acute or chronic environmental/biological insults disrupt normal AM activities such as phagocytosis, efferocytosis, and cytokine production, inciting oxidative stress, inflammasome activation, and in some cases forms of programmed cell death such as pyroptosis. Although these responses are indispensable for eliminating noxious particles and pathogens, such as Mycoplasma pneumoniae or Klebsiella pneumoniae, influenza A, or SARS-CoV-2, they can also derail the resolution phase by perpetuating inflammation, driving tissue remodeling and fibrosis, and thereby fueling chronic lung disorders such as chronic obstructive pulmonary disease (COPD), pneumoconiosis, and post-COVID interstitial lung disease. Moreover, environmental and microbial exposures modify AMs by altering receptor repertoires, intracellular phenotype by signaling cascades, and cross talk with epithelial and mesenchymal cells that collectively determine the disease trajectory. Elucidating how diverse environmental agents, together with pathogens such as M. pneumoniae, K. pneumoniae, influenza A, and SARS-CoV-2, shape AM biology is therefore pivotal for understanding the pathogenesis of COPD, pneumoconiosis, progressive fibrotic lung disease, and COVID-19-related pulmonary sequelae. This review brings together the current insights into exposure-driven modulation of AM functions, highlighting recent advances and identifying knowledge gaps relevant for therapeutic targeting of exposure-induced and pathogen-mediated lung pathology.}, }

Key reasons for recent pertussis outbreaks include suboptimal pertussis vaccination coverage (particularly for vaccination during pregnancy) and growing vaccination hesitancy. During the 2023-2024 pertussis outbreaks in Europe, adolescents aged 10-14 years and 15-19 years had the first and third highest incidence rates, respectively. To reduce pertussis burden, it is essential to strengthen vaccination programs in the indicated target groups. This requires increased awareness among healthcare professionals about the local epidemiology of pertussis and its clinical presentation, alongside reinforcement of the benefits of vaccination for disease prevention. In parallel, robust surveillance systems and strong public health capacity for early disease detection and response are crucial to effectively manage outbreaks and build resilience against future outbreaks. Infants remain at high risk for pertussis, with complications, hospitalisation, and death being more common than in other age groups. Immunisation programmes combining vaccination during pregnancy, to protect newborn infants until their primary immunisation series has induced immunity, and infant immunisation are key to reducing morbidity and mortality. Strategies to improve pertussis vaccination uptake among adolescents and adults, especially those with high-risk medical conditions, are also essential. Strengthening global collaborations to invest in and build surveillance systems capable of identifying and responding to future outbreaks, to align national policies, to scale up immunisation during pregnancy, and to adopt a life-long immunisation approach are needed to better control endemic pertussis and manage future outbreaks.}, }

Connectivity issues, audio distortion, and small sample sizes were common limitations. Risk of bias was moderate overall.<br><br>CONCLUSIONS: Telehealth is a clinically effective, feasible, and secure modality for CLP speech rehabilitation, comparable to in-person therapy when technologically optimized. Hybrid models and caregiver integration are recommended. Large-scale RCTs are needed to confirm long-term efficacy and cost-effectiveness WHAT THIS PAPER ADDS: What is already known on this subject Telehealth has been used for speech therapy in various paediatric populations, with evidence of comparable outcomes to in-person care during the COVID-19 pandemic. However, prior to this review, no systematic synthesis existed specifically evaluating telepractice for speech disorders in children with repaired cleft lip and/or palate, despite their unique needs for targeted articulation and resonance intervention. What this paper adds to existing knowledge This review demonstrates that telehealth-based speech therapy consistently improves articulation accuracy, resonance, and intelligibility in children with repaired cleft lip and palate, with gains equivalent to in-person therapy across synchronous and hybrid models. It identifies platform-specific acoustic fidelity (e.g., Google Meet, optimized hardware) and caregiver engagement as critical enablers, while highlighting connectivity and audio distortion as manageable barriers. These findings establish telepractice as a viable, scalable standard for cleft-related speech rehabilitation. What are the potential or actual clinical implications of this study? Clinicians can confidently implement hybrid telepractice models with encrypted platforms and external microphones to maintain treatment continuity, especially in underserved areas. Routine integration of caregiver training and AI-assisted feedback is recommended to enhance adherence and outcomes. Health systems should prioritize low-bandwidth protocols and standardized acoustic calibration to ensure equitable access.}, }

Compared with control groups (e.g., usual care, exercise advice, or no structured exercise), exercise interventions significantly improved exercise capacity (6-min walk distance), pulmonary function (forced vital capacity and forced expiratory volume in 1&#x202f;s), dyspnea (the modified Medical Research Council scale), physical pain, and health-related quality of life domains. The overall certainty of evidence for all outcome measures ranged from moderate to high.<br><br>CONCLUSION: Exercise programs of at least 6&#x202f;weeks are associated with improved cardiopulmonary function, reduced dyspnea and pain, and enhanced physical and health-related outcomes in patients with post-COVID-19 condition.<br><br>https://www.crd.york.ac.uk/PROSPERO/view/CRD42024538786.}, }

As PH progresses, increased pulmonary vascular resistance places chronic pressure overload on the right ventricle. Initially, the right ventricle adapts through hypertrophic remodeling, thickening the heart wall to maintain cardiac output. Over time, this adaptive phase shifts to maladaptive remodeling, marked by RV dilation, fibrosis, stiffness, and decoupling from the pulmonary artery, known as RV-pulmonary arterial uncoupling. This uncoupling reflects the inability of the right ventricle to sustain contractility against elevated afterload, ultimately leading to right heart failure, the primary cause of death in late-stage PH. Awareness of RV dysfunction has grown, extending beyond PH and pulmonary arterial hypertension to systemic conditions, such as heart failure with preserved ejection fraction, congenital heart disease, COVID-19, and complications of left ventricular assist device implantation. Research is increasingly focused on understanding the molecular and hemodynamic drivers of RV failure, including inflammation and altered cellular signaling. Innovations in imaging and biomarker discovery are improving the detection of maladaptive RV remodeling. Promising treatments, such as the activin signaling inhibitor sotatercept, may reduce pulmonary vascular resistance and support RV recovery. Further work is needed to enhance RV function and prevent failure. This review summarizes current knowledge on RV dysfunction in PH, emphasizing its mechanisms, clinical relevance, and therapeutic potential. Recognizing the right ventricle as a central therapeutic target may lead to more personalized, effective interventions and improved patient outcomes in PH and related conditions.}, }

Coordinated regional collaboration facilitated the detection and tracking of emerging SARS-CoV-2 variants. Local innovation also advanced diagnostic platforms and vaccine development, leading to regionally produced vaccines such as Soberana, Abdala, ARVAC, and Patria. These initiatives generated valuable clinical and immunological data, including characterization of inflammatory biomarkers associated with severe disease and evidence of hybrid immunity in highly exposed populations. However, persistent inequities in healthcare access, research investment, and manufacturing capacity continue to constrain regional self-sufficiency. Although collaboration among academia, industry, and government reduced certain external dependencies, structural limitations in funding stability, regulatory harmonization, and large-scale production remain.

Thus, it demands the urgency and global attention of past pandemics. Over 850 million people are affected, disproportionately impacting people in low- and middle-income countries. Although CKD can be detected with simple and cost-effective testing, it is a silent condition, often remaining asymptomatic until it has progressed to advanced stages where effective treatment options are limited. Early detection relies on systematic population-level screening, especially among individuals with comorbidities. The global response to CKD has remained largely silent: There is limited evidence of prioritization within health agendas and inadequate infrastructure for screening, surveillance, and treatment. Coordinated global action is required to halt this silent "pandemic," especially given advances in care and policy: New effective disease modifying therapies may lead to remission of CKD for many individuals, and the 2025 World Health Organization's adoption of the Kidney Health Resolution at the 78th World Health Assembly prioritizes kidney health to reduce the burden of noncommunicable diseases through promoting early screening, strengthening disease prevention, and improving access to care. In this review, we examine the failure to address the escalating CKD "pandemic" and explore how the use of low-cost and cost-effective screening tools, such as simple urine dipstick testing, and applying lessons learned from the COVID-19 pandemic are critical to further reframing CKD as a public health emergency and prioritizing kidney health on the global agenda.}, }

During the early phase of the COVID-19 pandemic, numerous cluster events were suspected to involve long-distance airborne transmission/inhalation. We conducted a comparative analysis of these cluster events to characterize outbreak settings and associated clinical parameters. Thirteen cluster events from 2020 attributed to the original SARS-CoV-2 strain were examined, including choral activities, indoor sports, and bus tours. Incubation periods and infection-hospitalization rates (IHRs) were compared across settings and against estimates from large-scale cohort studies that predominantly reflect transmission via direct deposition. Statistical analyses were performed using the Mann-Whitney U test, Student's t-test, and Fisher's exact test (p < 0.05). The mean incubation period in suspected long-distance airborne transmission/inhalation cases was 6.1 ± 3.9 days (median: 5 days; N = 176), with indoor sports and choral events showing significantly shorter incubation periods (p = 0.034). The average IHR was 6.7 ± 12.5%, with significantly higher rates in choral clusters (p = 0.013). Age-adjusted IHRs were lower in long-distance airborne transmission/inhalation-related clusters than those reported from contact-tracing datasets. This analysis provides an integrated evaluation of long-distance airborne transmission/inhalation settings and their associated clinical characteristics. Activities involving vigorous respiration may contribute to shorter incubation periods and higher disease severity, potentially reflecting increased viral inoculum at exposure.}, }

It plays a central role in shaping adaptive immunity by promoting the polarization, expansion, and maintenance of T helper 17 (Th17) cells, thereby driving the production of downstream effector cytokines such as IL-17A and IL-22. Under physiological conditions, IL-23 contributes to pulmonary immune homeostasis and host defense against bacterial and fungal pathogens. However, sustained or dysregulated IL-23 signaling promotes chronic inflammation and tissue damage. Beyond autoimmune diseases, where IL-23 is a well-established key mediator linked to disease severity and a validated therapeutic target, it has also emerged as a critical mediator in chronic lung diseases. Enhanced IL-23 signaling has been associated with increased disease severity, corticosteroid resistance, airway remodeling, and progressive tissue fibrosis, highlighting its contribution to both inflammatory and structural components of lung pathology. These findings suggest that IL-23 is not merely a bystander but an active driver of pathogenic processes in the respiratory system. In this review, we synthesize recent advances in understanding the role of IL-23 in chronic obstructive pulmonary disease, asthma, idiopathic pulmonary fibrosis, and coronavirus disease 2019. We further discuss the therapeutic potential of targeting IL-23 as a precision-guided strategy to modulate respiratory inflammation and remodeling, with particular emphasis on corticosteroid resistance, fibrotic endotypes, safety and pharmacologic tradeoffs, and the emerging role of IL-23-related biomarkers and molecular endotyping for precision-guided patient stratification and targeted intervention.}, }

The impaired ion transport leads to thickened mucus secretions, which in turn can cause pancreatic insufficiency, sinusitis, infertility and, particularly, chronic pulmonary infections. While bacterial colonization of the airways has been extensively studied, increasing evidence highlights the significant, yet underappreciated, role of respiratory viruses in exacerbating lung disease in people with CF (pwCF). This review provides a comprehensive overview of the pathogenesis, epidemiology, and clinical impact of key respiratory viruses, including respiratory syncytial virus (RSV), human rhinovirus (HRV), influenza viruses, parainfluenza viruses, coronaviruses, and emerging pathogens such as human bocavirus, as well as relevant non-respiratory viruses, such as Cytomegalovirus (CMV), Epstein-Barr virus (EBV) and hepatitis viruses. Viral infections in pwCF are associated, particularly in pediatric patients, with increased respiratory symptoms, higher hospitalization rate and long-term decline in lung function. Despite a similar incidence of viral infections to non-CF individuals, pwCF often exhibit more severe clinical outcomes, except for SARS-CoV-2 infection, which shows an incidence and severity unexpectedly attenuated in this cohort. Moreover, while CFTR modulators have dramatically improved clinical outcomes in pwCF, their effects on antiviral immunity remain poorly understood and are an area of active investigation. Elucidating virus-host interactions and the impact of CFTR restoration in this context is essential for optimizing preventive and therapeutic strategies against viral infections in CF.}, }

Given the presence of markedly elevated serum autoantibodies against G protein-coupled receptors, high-dose intravenous immunoglobulin therapy was initiated at 400 mg/kg per day for 5 consecutive days. After 4 weeks, a maintenance dose of 500 mg/kg was administered for 1 day, followed by two further maintenance cycles consisting of 500 mg/kg per day for 3 consecutive days, each given at 4-week intervals. In parallel, the patient underwent a cognitive stimulation intervention. Neurological symptoms were assessed with the Fatigue Assessment Scale and the WHO Disability Assessment Schedule 2.0, and the immunological profile was longitudinally analysed during intravenous immunoglobulin treatment. Fatigue scores normalised, neurocognitive performance returned to normal value, and quality of life improved after the first infusion and fully recovered within 1 year. Immunological profiling revealed the presence of an inverted CD4 to CD8 T-cell ratio that persisted during the whole follow-up. We also identified a CD8[+] T cell-monocyte complex and spontaneous IFNγ release. Intravenous immunoglobulin therapy was associated with a significant reduction of these complexes, spontaneous IFNγ and TNF production, markers of endothelial inflammation, and circulating autoantibody titres. This patient provides exploratory evidence that high-dose intravenous immunoglobulin was associated with sustained clinical recovery from long COVID over 1 year of follow-up, accompanied by immunological changes consistent with modulation of post-viral immune dysregulation, including a reduction in pathogenic T cell-monocyte synapses. Although causal inference cannot be established from a single patient, these findings suggest that this cellular interaction can contribute to long COVID and that immunomodulation could represent a rational therapeutic approach to be evaluated in selected patients.}, }

The COVID-19 pandemic redefined expectations for vaccine science, compressing traditional development timelines, and accelerating the adoption of novel platforms, such as mRNA and viral vectors. While these innovations significantly reduced global morbidity and mortality, they also exposed persistent barriers, including unequal distribution and widespread vaccine hesitancy fuelled by misinformation. This review evaluates the biochemical foundations of vaccine design, including antigen selection, adjuvant use, and delivery optimisation, alongside the emerging formulation strategies and vaccine-platforms integration. The review emphasises the need for continuous alignment between scientific progress and equitable access. By integrating historical context, technical advancement, and social determinants, this review highlights the imperatives for future vaccine strategies to be not only scientifically robust, but also globally inclusive and implementation ready. By positioning recent advancements within the historical timeline of vaccine science, this review argues that the post-COVID-19 era represents an acceleration of progress where speed, adaptability and global equity are essential for safeguarding the populations against current and emerging threats from the pandemics and localized infectious challenges in medical emergencies.}, }

The COVID-19 pandemic has had profound and multifaceted effects on healthcare delivery and infection control practices, potentially influencing the epidemiology of CDI.<br><br>OBJECTIVE: To assess whether the coronavirus disease 2019 (COVID-19) pandemic has influenced the incidence of CDI and to explore potential contributing factors.<br><br>METHODS: This systematic review and meta-analysis was conducted in accordance with the PRISMA guidelines. Seven databases were searched for relevant literature published from December 2019 to October 2025. Study quality was assessed via the Newcastle&#x2012;Ottawa Scale (NOS) and the Joanna Briggs Institute (JBI) critical appraisal tools. Random- or fixed-effects models were selected according to heterogeneity. Publication bias was evaluated via funnel plots and Egger's test, and sensitivity analyses were conducted. The primary outcome was the incidence rate of CDI, expressed as cases per 10,000 patient-days. Incidence rate ratios (IRR) were calculated to compare the incidence of CDI between the prepandemic and pandemic periods.<br><br>RESULTS: Sixteen studies were included. The pooled CDI incidence rate was 4.42 (95% CI: 3.37-5.46) per 10,000 patient-days in the prepandemic period and 3.80 (95% CI: 2.63-4.96) per 10,000 patient-days during the pandemic. The pooled incidence rate ratio was 0.80 (95% CI: 0.67-0.97), indicating a significant reduction in the incidence of CDI. This decline was associated with changes in medical practices (e.g., the suspension of nonurgent and high-risk procedures), antimicrobial stewardship practices, and strengthened infection control measures (e.g., enhanced hand hygiene and environmental disinfection) during the pandemic.<br><br>CONCLUSION: Compared with the prepandemic period, the incidence of CDI decreased significantly during the COVID-19 pandemic. This finding suggests that strengthened infection prevention measures, improved antimicrobial stewardship, and adaptations in healthcare delivery may have contributed to reduced CDI transmission. Reinforcing these evidence-based foundational strategies may help mitigate &#x200c;the risk of CDI and other healthcare-associated infections during future public health emergencies.}, }

PubMed, Epistemonikos, LILACS, and Google Scholar were searched for randomized and observational studies evaluating non-pharmacological rehabilitation in adult ICU survivors of COVID-19. Risk of bias was assessed using RoB 2 and ROBINS-I tools. Given substantial clinical and methodological heterogeneity, quantitative meta-analysis was not performed; a structured narrative synthesis was undertaken.ResultsFourteen studies met inclusion criteria. Five incorporated comparator groups, while nine employed uncontrolled pre-post designs. Interventions ranged from early ICU mobilization to inpatient and outpatient pulmonary rehabilitation. Controlled studies reported variable between-group benefits in dyspnea and functional outcomes, whereas observational studies consistently described within-group improvement over time. However, most studies were at moderate to serious risk of bias, and heterogeneity in intervention timing, dosage, and outcome assessment limited comparability.ConclusionsNon-pharmacological rehabilitation in ICU survivors of COVID-19 is associated with improvement over time; however, the certainty of causal effectiveness remains low. ICU survivors constitute a distinct recovery population within the broader post-COVID spectrum. Adequately powered, multicenter randomized trials with standardized protocols and harmonized outcomes are required to establish long-term effectiveness.}, }

Understanding its genomic trajectory and policy implications is critical. Methods This was a retrospective convergent mixed-methods study integrating genomic sequencing (GISAID, INSACOG), epidemiological counts (ICMR, WHO, CDC), and policy/advisory analysis (MoHFW, WHO-SEARO). Data were analysed across January-May 2025 using prevalence tracking, hospitalisation comparisons, and thematic policy review. Results Genomic analyses showed NB.1.8.1 carrying lineage-defining spike mutations (A435S, V445H, T478I) linked to transmissibility and immune escape. While prevalence rose in China, India reported <5% share. Hospitalisation burdens remained lower in India than in China. India's policy response showed increasing alignment between genomic surveillance outputs and subsequent public health advisories, with targeted booster promotion and enhanced surveillance in high-incidence States. Interpretation and conclusions NB.1.8.1 illustrates the dynamic evolutionary trajectory of SARS-CoV-2. India's adaptive genomic surveillance and flexible public health frameworks contributed to mitigating clinical severity, though surveillance gaps and rural under-reporting remain concerns. Sustained genomic tracking, booster equity, and real-time advisory mechanisms are needed to strengthen preparedness.}, }

They were surveyed using a xerostomia assessment questionnaire and underwent the modified Schirmer test (MST) to measure their salivary flow rate. Results Overall, n=31(62%) of participants reported one or more xerostomia-related symptoms after recovery. "Feeling of dry mouth" (n=22, 44%) was the most common, followed by nocturnal water intake (n=18, 36%), difficulty swallowing dry food (n=7, 14%), and reliance on liquids during swallowing (n=6, 12%). Hyposalivation (MST <15 mm at 3 min) was observed in 10% (n=5) of participants, all of whom were infected during the second wave (Delta variant). A significant association was noted between self-reported dry mouth and MST findings (P=0.029). Symptoms persisted up to 15 months post-recovery.

However, it suffers from chronic underfunding and design flaws. Financial sustainability remains a challenge, especially due to low central Spanish government contributions and regional disparities. Nonetheless, the LTC system has yielded significant economic returns through job creation and increased female labour participation. LTC benefits have also influenced family decisions: reducing savings, increasing the supply of informal caregivers and delaying early retirement. The COVID-19 pandemic exposed structural vulnerabilities, particularly in residential care. Moreover, while the navigation across the LTC system ensures horizontal equity, inequity is documented in the form of providing the benefits.<br><br>CONCLUSIONS: After almost two decades of the Spanish LTC system, evidence calls for adequate and stable financing mechanisms to achieve sustainability.

We conducted a systematic review and meta-analysis according to the PRISMA 2020 guidelines. Studies reporting retinal or macular complications post-COVID-19 vaccination were searched via Ovid MEDLINE, Embase, and the Cochrane Library. Extracted data included study demographics, outcome, latency, and vaccine subtype. The risk of bias was assessed, and a random-effects meta-analysis was performed to estimate the pooled relative risk of ocular complications following vaccination. A total of 173 studies were included, with the most frequently reported outcome being retinal vascular occlusions (n = 107). The distribution of ocular complications was significantly different between COVID-19 vaccine and infection exposure (p = 0.014). Most complications occurred within the first month of exposure, particularly among mRNA vaccines, which had a significantly different adverse event rate across vaccine platforms (p = 0.0084). A meta-analysis resulted in a pooled relative risk of 2.40 (95% CI: 0.33-17.73) for retinal vein occlusion following vaccination; however, due to the uncertainty around the estimate, the association remains inconclusive.

Hesitancy toward routine childhood vaccines was generally low (3%-20%), whereas hesitancy toward newer or non-mandatory vaccines, including COVID-19, influenza, and HPV, exceeded 50% in some settings. Studies reporting father-specific data indicated higher hesitancy among fathers, particularly regarding safety, novelty, and possible long-term effects.

Searches were conducted using PubMed and Embase between September 2024 and February 2025, yielding 7572 unique records. After dual screening, 47 articles met inclusion criteria, with an additional 8 identified through citation searching, for a total of 55. Non-English articles were translated using Google Translate. Data were extracted and thematically analyzed through iterative familiarization, keyword identification, coding, and consensus discussion.<br><br>RESULTS: Of the 55 included articles, most originated from the European Region (61%) and the Americas (52%), with additional representation from Africa (19%), the Western Pacific (8%), Eastern Mediterranean (5%), and Southeast Asia (5%). Percentages exceed 100% because several studies reported across multiple regions. Study designs were predominantly descriptive (60%) with fewer randomized controlled trials (22%), observational (18%), and cohort studies (2%). COVID-19 accounted for the majority of articles (58%), followed by HIV/AIDS (20%), Ebola (13%), H1N1 (2%), and Zika (4%); no eligible studies addressed SARS or MERS. Operational themes included policy (73%), resources (55%), networks (53%), infrastructure (47%), technology (45%), study design (31%), and communication (22%). Publications peaked during pandemic years, reflecting intensified research activity. Reported challenges included protocol-practice misalignment, fragmented infrastructure, regulatory bottlenecks, and under-resourced sites. Reported practices included early site engagement in protocol development, streamlined ethics and contracting processes, investment in digital and decentralized infrastructure, and cross-trained staff. Gaps included limited use of adaptive trial designs and insufficient cross-national collaboration.<br><br>CONCLUSIONS: Clinical trial sites implemented systemic operational changes to sustain research during pandemics. Key lessons include the need to strengthen infrastructure, workforce capacity, and institutional adaptability, and the need to address persistent global inequities. Institutionalizing early site engagement, adaptive designs, and equitable collaboration will be essential to enable timely and resilient clinical research responses in future pandemics.}, }

Area postrema syndrome (APS), marked by intractable nausea, vomiting, and hiccups, is a recognized but less common initial manifestation. Post-infectious autoimmunity triggered by SARS-CoV-2 has been increasingly associated with NMOSD pathogenesis; however, the clinical significance of direct viral neuroinvasion and its relationship to divergent patient outcomes remains poorly understood.<br><br>METHODS: We report two female patients who developed isolated APS shortly after COVID-19 infection. Both patients underwent comprehensive neurological evaluation, including brain and spinal magnetic resonance imaging (MRI), cerebrospinal fluid (CSF) analysis with metagenomic next-generation sequencing (mNGS), and serological testing for aquaporin-4 immunoglobulin G (AQP4-IgG), myelin oligodendrocyte glycoprotein immunoglobulin G (MOG-IgG), and glial fibrillary acidic protein immunoglobulin G (GFAP-IgG) using cell-based assays. Clinical outcomes were compared in the context of antibody serostatus and treatment strategies. A review of the relevant literature on post-COVID NMOSD was also performed.<br><br>RESULTS: Both patients presented with intractable vomiting and hiccups following SARS-CoV-2 infection, and MRI demonstrated isolated T2/FLAIR hyperintense lesions in the dorsal medulla consistent with area postrema involvement. SARS-CoV-2 RNA sequences were detected in the CSF of both patients via mNGS, suggesting direct viral neuroinvasion or blood-brain barrier compromise. Despite similar initial presentations, their outcomes diverged dramatically. Patient 1 was AQP4-IgG negative, responded well to immunotherapy with intravenous immunoglobulin and corticosteroids followed by mycophenolate mofetil maintenance, and remained relapse-free at 12-month follow-up with significant lesion regression on MRI. Patient 2 was AQP4-IgG positive in both serum and CSF, and despite acute treatment, experienced a fatal relapse 6 months later with longitudinally extensive transverse myelitis while on low-dose prednisone monotherapy.<br><br>CONCLUSIONS: Isolated APS may represent an important yet under-recognized manifestation of post-COVID-19 autoimmune neuroinflammation. Detection of SARS-CoV-2 in CSF supports a role for direct viral neuroinvasion as a localized inflammatory stimulus. AQP4-IgG serostatus serves as a critical prognostic determinant: seronegativity is associated with a benign, monophasic course, whereas seropositivity mandates prompt initiation of potent immunosuppressive therapy to prevent devastating relapses. Clinicians should maintain a high index of suspicion for NMOSD in patients with unexplained persistent vomiting following COVID-19, and perform urgent neuroimaging and antibody testing for early risk stratification.}, }

The epicenter of clade I mpox is within the Democratic Republic of Congo (DRC) where two subclade consists of Ia and Ib are now in circulation and maintain their transmission from human to human. As of late 2024, worldwide mpox cases had surpassed 100,000 across 127 nations, with the World Health Organization reporting over 260 fatalities. CDC recently reported that the spread of clade I is no longer limited to Africa, highlighting its growing potential to become a pandemic. The World Health Organization (WHO) declared the disease an international public health emergency on August 14, 2024. This undoubtedly raises the question of whether global outbreaks of mpox represent the onset of another full-blown pandemic. Although Monkeypox can lead to other public health issues (especially in areas where it is not usually endemic), it is unlikely to become a pandemic on the same scale as COVID-19. Moreover, it is more containable due to vaccine availability, its transmission dynamics, and lessons learned from COVID-19. Nonetheless, it is still important to remain vigilant to prevent outbreaks from spreading, particularly in vulnerable populations and regions with limited healthcare resources.}, }

These limitations hinder comparisons, emphasising the need for standardised evaluation. This 10-year retrospective cohort study investigates IAN injury rates following mandibular osteotomies, focusing on medium-long term outcomes and risk factors. A retrospective cohort study was conducted at a tertiary orthognathic centre (2014-2024) on sagittal split osteotomies, performed either as stand-alone or as part of bimaxillary surgeries. Altered sensation was assessed via patient-reported outcomes during clinical follow ups (0-60+ months). While a final review was typically conducted at 6 months, extended follow ups addressed nerve symptoms, revision surgeries, or COVID-19 disruptions. Chi squared tests, Fisher's exact test and odds ratios evaluated associations with demographics, split quality, and nerve injuries. The primary outcome was altered sensation at ≥6 months. Of 221 procedures, 75.6% (n = 167) had follow ups ≥6 months, with 44.3% (n = 74/167) reporting altered sensation, primarily in the lower lip. Rates were 49% (n = 49/100) at 6-12 months, 50% (n = 13/26) at 13-18 months, and 29.2% (12/41) beyond 18 months. Females (OR = 1.07) and the 41-50 age group (50%, n = 2/4) showed slightly increased sensory changes, although they were not statistically significant. Unsatisfactory splits had higher altered sensation rates (60%, n = 6/10) compared with satisfactory splits (43.9%, n = 65/148) although these were not statistically significant (p = 0.15). Among documented nerve injuries, 100% (n = 7) resulted in sensory changes at ≥6 months. Altered sensation affected 44.3% (74/167); non-standardised follow up limits interpretation and supports standardised neurosensory reporting.}, }

While clinical management has reduced case-fatality rates, a substantial proportion of patients develop LC, a heterogeneous syndrome with long-term symptoms. This complex continuum requires therapeutic strategies for both the acute and chronic phases. Plasma proteomics has emerged as a powerful tool in precision medicine, offering insights into systemic molecular changes and disease trajectories. Using targeted and untargeted proteomic analyses, researchers can identify disease-relevant pathways, perform cellular deconvolution to assess tissue-specific contributions, and pinpoint therapeutic targets for both acute infection and persistent symptoms. Combined with bioinformatics and machine learning, these proteomic insights support biomarker discovery and drug repurposing strategies.<br><br>SUPPLEMENTARY INFORMATION: The online version contains supplementary material available at 10.1186/s12014-026-09601-8.}, }

Direct testing of pathogens often requires a high-level biosafety containment, which can restrict performance evaluations to smaller scales that may have limited translatability to the complexities of real-world indoor environments. Therefore, using viral surrogates that are safer to work with than target pathogens offers many potential benefits, including aerosol testing in more realistic conditions. This scoping review analyzes surrogate selection and use across aerosol, surface, and suspension-based tests and identifies bridges in surrogate selection considerations. A qualitative analysis of 133 studies was conducted to highlight trends, knowledge gaps, and future directions toward standardized surrogate selection frameworks. This review finds that Enterobacteria phage MS2 (MS2) and other bacteriophages are commonly used due to their practicality and safety. There are limited examples of concurrent pathogen and surrogate testing to assess suitability, which is highly context-dependent on the test conditions. Beyond virucide testing, the surrogate selection considerations discussed herein are informative for research on the persistence, transmission, transport, behavior, and nonchemical management of airborne viruses.}, }

There were 790 patients diagnosed with COVID-19 and 484 controls. Acoustic measurements revealed that COVID-19 patients had an increased harmonic-to-noise ratio (HNR) (27.14 vs. 41.37&#x2009;dB), and increased fundamental frequency (177.66 vs. 172.81&#x2009;Hz), jitter (0.73 vs. 0.31), and shimmer (4.43 vs. 3.42). Auditory-perceptual measurements indicated that COVID-19 patients had an increased Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) score (11.46 vs. 2.15).

The current research suggests negative effects of COVID-19 on the voice; however, this is the first systematic review to summarize its effects with measurable outcomes. More studies with vocal measurements taken at different time points following infection are needed to understand the full long-term effect of COVID-19 on the voice.

Effective control of inflammation reduces CV events, whereas glucocorticoids increase the risk in a dose- and duration-dependent manner, even at ≤ 5 mg prednisolone/day. Disease-modifying antirheumatic drugs especially tumor necrosis factor (TNF) inhibitors, are largely protective through the reduction of systemic inflammation. For patients receiving Janus kinase (JAK) inhibitors or long-term glucocorticoid therapy, a structured CV risk assessment and guideline-based management of modifiable risk factors (including lipid optimization/statin therapy) are essential. Primary prevention should be based on the cardiovascular prevention guidelines of the European Society of Cardiology (ESC). Vaccinations (influenza, COVID-19, pneumococcus, respiratory syncytial virus, zoster) represent an effective pillar of CV prevention in populations at cardiovascular risk; however, evidence in patients with inflammatory rheumatic diseases is still lacking. The main challenge for CV prevention remains implementation: digital clinical reminders/decision support systems and multicomponent strategies can improve the implementation of recommendations.}, }

Most reviews (78%) were rated critically low in quality. Individual-level barriers were dominated by reduced health literacy (reported in 26 reviews), including inadequate access to sign language health information, limited family awareness, and poorer knowledge of medicines and preventive practices. Socioeconomic status, rural residence, minority ethnic background and limited family support were also linked to reduced healthcare access. Environmental factors included communication barriers, low Deaf awareness among healthcare professionals and shortages of qualified interpreters, all of which fostered Deaf people&#x2019;s mistrust and disengagement with healthcare.

This review provides an updated overview of the medicinal chemistry of indolizine and isoindoles, with particular emphasis on compounds demonstrating activities against infectious pathogens. Representative examples are highlighted to illustrate structure-activity relationships (SARs), scaffold-based optimization strategies, and emerging mechanistic insights. Relevant synthetic methodologies are discussed only in the context of biologically active compounds to provide a framework for rational design. Collectively, this review underscores the therapeutic potential of indolizine- and isoindole-derived scaffolds as versatile frameworks for anti-infective drug development and highlights opportunities for further chemical and biological exploration.}, }

This study uses Joint External Evaluation (JEE) scores and After-Action Review (AAR) findings to assess public health emergency preparedness across 15 West African countries and identify gaps between theoretical assessments and operational response capacity.<br><br>METHODS: A mixed-methods approach compared JEE scores (2016-2023) with thematic analysis of AAR findings from major outbreaks. Consistency between JEE-predicted capacities and AAR-reported challenges was assessed using a three-level rating system (High/Moderate/Low) and the Kappa statistic.<br><br>RESULTS: In 68 of 105 technical area comparisons (65%) of cases, JEE scores accurately predicted weaknesses in laboratory systems and workforce development. However, in 37 comparisons (35%) of cases, JEE scores overestimated preparedness, particularly in risk communication(all15 countries,100%), real-time surveillance(13 of 15 countries, 87%), and cross-border coordination, where countries with high scores faced operational failures during outbreaks. AARs revealed logistical bottlenecks, supply chain disruptions, and coordination failures not captured by JEEs. Alignment with SDG 3.d (health security), SDG 10 (inequalities), SDG 17 (partnerships), and SDG 9 (infrastructure) underscores broader development implications.<br><br>CONCLUSION: While JEE is valuable for baseline assessment, it incompletely predicts real-world outbreak response performance. Integrating AAR findings into national planning and refining JEE indicators to include operational metrics will enhance health security evaluations. Regionally coordinated action through WAHO is essential for addressing gaps and building resilient systems aligned with sustainable development goals.}, }

National workforce data, expert commentaries, and strategic frameworks from academic radiology and healthcare leadership literature were reviewed to contextualize current challenges and proposed solutions. The radiology workforce faces escalating pressure driven by rapidly increasing imaging volumes, limited growth in the number of practicing radiologists, and rising attrition rates. Between 2008 and 2018, radiologist workloads nearly doubled while workforce expansion was much smaller, exacerbating workload imbalance, burnout, and professional dissatisfaction. The COVID-19 pandemic exacerbated workforce challenges by causing an exodus of workers and making on-site work more challenging. Although short-term mitigation strategies exist, sustainable long-term solutions require coordinated cultural and structural changes that prioritize strategic hiring, transparent career advancement pathways, protected academic and professional development time, and optimized workflow efficiency supported by technology. In conclusion, effective management of the radiology workforce shortage necessitates integrated operational and cultural approaches, with departments implementing comprehensive and tailored interventions to expand workforce capacity, enhance professional fulfillment, and maintain high-quality patient care.}, }

This article investigates the potential association between modified mRNA (modRNA) COVID-19 vaccinations and the development of haematopoietic cancers. We present a case involving a healthy, young, athletic woman who developed acute lymphoblastic leukaemia (ALL) and lymphoblastic lymphoma (LBL) following her second dose of the Pfizer/BioNTech COVID-19 vaccine (Comirnaty®). This case is part of an expanding body of literature documenting similar occurrences after modRNA vaccinations, which we critically examine. Emerging evidence suggests that the biodistribution and persistence of modRNA, facilitated by lipid nanoparticles, can affect various tissues and organs, including the bone marrow and other blood-forming organs. Notably, modRNA vaccines exhibit a particular affinity for the bone marrow, potentially influencing the immune system at multiple levels and triggering both autoimmune disorders and neoplastic processes. In this article, we assess the risk of developing haematopoietic cancers post-modRNA vaccination based on current scientific literature and explore the reported potential genetic and molecular mechanisms involved in disease pathogenesis. By integrating clinical observations and current research, we aim to provide valuable insights into the potential carcinogenic outcomes associated with modRNA vaccination.}, }

Coronaviruses damage mitochondria in airway epithelial cells (AEC), pulmonary artery smooth muscle cells (PASMC), pulmonary artery endothelial cells, immune cells and cardiomyocytes by causing rapid transcriptomic changes in nuclear-encoded genes regulating mitochondria and by viral proteins interacting with host mitochondrial proteins. Coronavirus infection causes mitochondrial depolarization, mitochondrial transition pore (MTP) opening, inhibition of the electron transport chain (ETC) and ATP synthetic apparatus, increased mitochondrial fission, apoptosis, and impaired mitochondrial oxygen sensing. Within hours of infection, SARS-CoV-2 induces transcriptional reprogramming of genes relevant to the mitochondrial matrix in AECs, downregulating mRNA encoding ETC complex I components and the ATP synthesis complex. These bioenergetic consequences of SARS-CoV-2 mitochondriopathy may contribute to long COVID. Infection also upregulates dynamin-related protein 1 (DRP1), activating mitochondrial fission while promoting apoptosis by activating apoptosis inducing factor (AIF) and caspase 7. Even without infection, transfection with specific coronaviral proteins opens the MTP and depolarizes the mitochondria, or activates DRP1 and AIF, promoting AEC damage or apoptosis, thereby contributing to diffuse alveolar damage. In human PASMCs, coronaviral M and Nsp9 proteins suppress hypoxic pulmonary vasoconstriction (HPV), a homeostatic mechanism in PASMCs that uses a mitochondrial oxygen sensor to redistribute blood flow to well-ventilated lung regions during pneumonia. Impairment of HPV, seen as intrapulmonary shunting, contributes to the profound hypoxaemia in COVID-19 pneumonia. Coronavirus-induced mitochondriopathy may have therapeutic relevance as blocking AIF-induced apoptosis or enhancing HPV appears beneficial in a MHV-1 model of COVID-19 pneumonia.}, }

This review examines the gap between expectations and reality using historical parallels, conceptual considerations, and recent methodological evidence. Experiences with antioxidant supplementation, vitamin D, the microbiome, and the Human Genome Project illustrate a recurring pattern: early studies report large effects that diminish or disappear in larger, higher-quality studies. Meta-epidemiological work and the 'cursed auction' analogy explain why early and small studies systematically overestimate effects. Conceptually, individualized clinical risk remains a group-based construct, constrained by the reference class problem and irreducible uncertainty. Methodologically, many AI models in rheumatology suffer from small and heterogeneous datasets, overfitting, inadequate handling of missing data, poor calibration, and limited external or prospective validation. The failure of COVID-19 prediction models and the neutral trial of the Ada diagnostic assistant in rheumatology illustrate how strong retrospective performance often collapses in real-world use. In contrast, AI performs well in high signal-to-noise domains with abundant, structured data. Overall, AI can generate valuable insights and support narrowly defined tasks, but it cannot yet overcome the fundamental limits of noisy clinical data and group-based risk. Progress in rheumatology will require realistic expectations, large representative datasets, transparent methods, rigorous validation, and a focus on robust, interpretable tools that improve decisions for populations and well-defined patient subgroups rather than precise individual prediction.}, }

Recent regional outbreaks, including the January 2025 surge in northern China, highlight hMPV's capacity to cause significant above-seasonal transmission events, particularly in settings with immunity debt following prolonged non-pharmaceutical interventions. This review synthesizes current knowledge on hMPV epidemiology, genetic diversity, transmission dynamics, pathogenesis, host immune interactions, diagnostic approaches, and therapeutic and vaccine development efforts. A comprehensive literature search was conducted across PubMed, Scopus, Web of Science, and ScienceDirect with no publication date restriction, using MeSH and free-text terms including "hMPV," "epidemiology," "immune response," "diagnosis," "treatment," and "pandemic preparedness." Relevant reference lists were hand-searched to identify additional studies. Eligible articles included molecular, clinical, observational, and epidemiological studies; case reports and commentaries were excluded unless they provided unique outbreak insights. Findings emphasize that hMPV represents a growing public health concern due to limited awareness, diagnostic overlap with other viral pathogens, and the absence of targeted therapeutics or licensed vaccines. Strengthened surveillance, improved diagnostic capacity, and accelerated research into immunopathogenesis and vaccine platforms are urgently needed. Integrating hMPV into regional outbreak preparedness frameworks rather than pandemic-level frameworks applicable to influenza or SARS-CoV-2 while fostering collaborative research and proportionate public health communication, is essential to mitigate its future impact.}, }

The article considers the claim of bioethicists Maxwell J Smith and Ross Upshur that there is 'collective amnesia' when pandemics arise, to foreground the importance of uncovering and evaluating the visual, literary and media histories of pandemics past. Analysis of literary-historical research presented as part of the interdisciplinary 'Media and Epidemics' project, which analysed the visual and literary cultures of historic epidemics of influenza, demonstrates how historic literature and media collides with present-day public health discourse. Examining past epidemics reveals shared issues raised by COVID-19 media reportage concerning the historic role of storytelling, stigmatisation and fears of contagion. While COVID-19 haunts our recent past, there remains '[a]n urgency to understanding how narratives are constructed and understood between communities and their impact on structural factors, such as health policy' which can be enriched through 'a framework of public health humanities'. In conclusion, the proposed antidote to a global 'amnesia' centres on privileging memory, learning actionable lessons and telling stories of disease within collaborative medical humanities forums which unite literature and science.}, }

We conducted a retrospective cohort study of adults with hypertension and no prior cardiovascular events in the Montefiore Health System, comparing those with and without COVID-19 over up to 4.5 years post-infection. Outcomes included first-time myocardial infarction (MI), heart failure (HF), stroke, all-cause mortality, and major adverse cardiovascular events (MACE). Multivariate regression and inverse-probability weighting adjusted for demographics, comorbidities, socioeconomic status, and COVID-19 vaccination. Adjusted hazard ratios (HRs) with 95% confidence intervals were calculated. Sub-analyses examined hypertension stage and acute COVID-19 blood biomarkers in relation to outcomes. Among 75,180 hypertensive patients, hospitalized COVID-19 was associated with increased risk of first-time MI (adjusted HR = 1.40 [1.21-1.63]), HF (1.59 [1.45-1.75]), stroke (1.35 [1.17-1.57]), all-cause mortality (2.51 [2.17-2.90]), and MACE (1.65 [1.54-1.77]) compared to COVID-negative individuals. Non-hospitalized COVID-19 patients had elevated risks of HF (1.17 [1.06-1.30]) and MACE (1.14 [1.05-1.23]). Hospitalized COVID-19 was associated with an increase in MACE risk by 75% in those with normal blood pressure, and by 126% and 148% in those with elevated blood pressure and stage 1 hypertension, respectively. Abnormal C-reactive protein, creatinine, lactate dehydrogenase, D-dimer, hemoglobin, and neutrophil-to-lymphocyte ratio predicted higher MACE risk. COVID-19, irrespective of disease severity, puts hypertensive patients at greater risks of worse cardiovascular outcomes, especially those with more advanced hypertension.

In addition, a supplementary exploratory analysis was performed using laboratory-derived PlGF data to assess analytical variability and biological associations. Non-parametric methods were applied, including Mann-Whitney U testing to compare PlGF distributions by analytical sample classification and Kendall's tau correlation to evaluate associations with gestational age and the sFlt-1/PlGF ratio. The systematic review identified consistent epigenetic alterations involving DNA methylation, histone modifications, and non-coding RNAs across maternal and placental tissues. Supplementary analysis demonstrated significantly higher and more variable PlGF concentrations in analytically classified measured samples compared with accepted samples (P = 0.03), suggesting an influence of analytical factors on biomarker distribution. PlGF levels showed a positive association with gestational age (τ = 0.32, P = 0.04) and an inverse association with the sFlt-1/PlGF ratio (τ = -0.41, P = 0.02). These findings support PlGF as a biologically relevant marker of gestational progression and angiogenic balance while underscoring the importance of rigorous analytical quality control.

Numerous studies have established a consistent association between infections -particularly respiratory infections- and an increased risk of cardiovascular events, stroke, arrhythmias, and both cardiovascular and all-cause mortality. The underlying pathophysiological mechanisms include systemic inflammation, immune activation, endothelial dysfunction, prothrombotic states, sympathetic stimulation, and elevated myocardial oxygen demand. In respiratory infections, these effects are further exacerbated by hypoxemia and impaired gas exchange. Such alterations can trigger de novo cardiovascular events or exacerbate preexisting conditions, such as ischemic heart disease or heart failure. In this context, robust evidence supports the safety of vaccines against Influenza, Pneumococcus, Respiratory Syncytial Virus, COVID-19, and Herpes Zoster in adults, including those with established cardiovascular disease or risk factors. Moreover, these vaccines have demonstrated efficacy in reducing cardiovascular events by mitigating infection-related complications. Notably, influenza vaccination has proven safe even during the acute phase of myocardial infarction, when administered during hospitalization. Despite this strong evidence base, vaccination rates remain suboptimal among individuals with cardiovascular disease, both in Argentina and across Latin America. This consensus document reviews the current evidence linking infections and cardiovascular events, and highlights vaccines as a safe and cost-effective strategy for primary, secondary, and tertiary prevention. It also provides concrete recommendations to improve vaccine coverage and reduce residual cardiovascular risk in the region.}, }

This led to the publication of the New Global ARDS Definition in 2023, which introduced new diagnostic categories and broader diagnostic tools. The ongoing need for refinement, combined with the pathophysiological heterogeneity, motivated an exploration by expert clinician and researchers about the value of defining and subphenotyping ARDS for research, education, and clinical care.

Though historically regarded as inconsequential, recent outbreaks, most notably COVID-19 caused by SARS-CoV-2, highlight their significant impact on global health. SARS-CoV-2 possesses a 27-31 kb, complex genome encoding multiple structural and non-structural proteins. The membrane/matrix (M) glycoprotein is the most abundant structural component of the viral envelope and confers the minimal requirement for virion formation. Its highly conserved structure, featuring three transmembrane domains, facilitates interactions with other viral proteins that are essential for assembly, budding, and maintaining the integrity of the viral envelope. Beyond its canonical functions in virion assembly and egress, emerging evidence suggests the M protein influences early infection processes, modulates host immune responses, and may serve as a promising antiviral target. This mini review consolidates current knowledge on the structure, multifunctional roles, and therapeutic potential of the coronavirus M protein, emphasizing the necessity for further research into its diverse functions throughout the viral lifecycle.}, }

The final search was conducted in January 2024, through the databases MEDLINE Complete, EMBASE, CINAHL, PsycINFO, AMED Allied and Complementary Medicine. Studies were eligible for inclusion if they reported qualitative findings on the (dis-)advantages of teleconsultations for allied health services from a patient's and/or provider's perspective. The screening process was conducted by two independent researchers, while the data extraction and inductive analysis were performed by the first author.<br><br>RESULTS: We identified 116 eligible articles. Eight categories were identified from a patient's perspective, including improved access to care, resource savings, convenience, comfort, reduced infection risk, effects on therapy, privacy, and patient-provider relationship. From the provider's perspective, additional categories included telehealth as a trigger for change and improvement, the patients in their own home, disruptions, interpreters, efficiency, changes to workday, and safety and risks.<br><br>CONCLUSION: While there are clear advantages, such as improved access to care, and disadvantages, such as the lack of hands-on treatment, the impact of telehealth often depends on the individual context of both the provider and the patient. Although some aspects are broadly relevant across all allied health professions, there are notable differences in the suitability of telehealth for specific services. Understanding the disadvantages and advantages of teleconsultations is key to informing policies and identifying suitable applications of telehealth.}, }

Endothelial-to-mesenchymal transition (EndMT) has recently emerged as a critical, yet underrecognized, pathway hijacked by oncoviral pathogens to modulate endothelial plasticity within the cardiovascular system. Accumulating evidence indicates that Oncogenic and non-oncogenic viruses, including Kaposi's sarcoma-associated herpesvirus (KSHV/HHV-8), severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), human immunodeficiency virus (HIV), and other endothelial-tropic viruses, directly manipulate host signalling networks, such as TGF-β, Wnt/β-catenin, Notch, and NF-κB, to induce partial or complete EndMT. This virus-driven EndMT contributes to vascular remodelling, chronic inflammation, aberrant angiogenesis, and the development of oncoviral-associated cardiovascular pathology and vascular tumours. The present review integrates current virological and mechanistic insights into EndMT as a hijacked host process, highlighting its role at the virus-host interface and discussing emerging antiviral and pathway-targeted strategies aimed at limiting oncovirus-mediated endothelial dysfunction.}, }

This review systematically evaluates the role of BCG vaccination in enhancing innate immune responses and its utility against COVID-19, focusing on mechanisms like trained immunity and cross-protection. It also discusses recent studies on BCG's impact on COVID-19 outcomes. Preliminary clinical trial findings suggest potential benefits of BCG vaccination against COVID-19, but the evidence remains inconclusive.

Despite emerging initiatives, most African facilities remain limited to downstream fill-and-finish operations, while full vaccine antigen manufacturing capacity is largely absent. This perspective paper examines the critical role of Technology Transfer (TT) and Intellectual Property (IP) access in achieving Africa's vaccine independence. Effective TT must extend beyond documentation to include unspoken know-how, on-site mentorship, regulatory dossiers, and supply-chain integration. Simultaneously, pragmatic IP frameworks through voluntary licensing, patent pooling, and time-bound waivers are essential to enable lawful and sustainable local production. Drawing lessons from mature European and U.S. ecosystems, the paper highlights the need for regional manufacturing clusters, harmonized regulatory systems under the African Medicines Agency (AMA), and African pooled procurement mechanisms to ensure market viability. Persistent challenges such fragmented regulation, supply-chain fragility, limited skilled human capital, and uncertain financing continue to constrain progress and highlight the imperative for political commitment to be operationalized through sustained structural investments. Africa's vaccine sovereignty will depend on aligning TT with IP reform, regional cooperation, and predictable market assurance, transforming the continent from a dependent recipient into a resilient and globally competitive vaccine producer.}, }

One persistent difficulty is the rapid molecular detection of pathogenic microorganisms and viruses. Taq DNA polymerase remains an essential component for COVID-19 molecular detection. Taq DNA polymerase exhibits a high level of thermostability, which results from tighter hydrophobic packing, increased salt bridges, shortened loops, and proline substitutions that reduce flexibility, enabling activity above 90 °C. In addition, engineered variants address limitations by improving fidelity, processivity, and stability. The enzyme´s thermostability has significantly increased the efficiency, automation, and specificity of PCR. Hot-start modifications using antibodies, aptamers, or chemical inhibitors further reduce non-specific amplification, strengthening its role in sensitive diagnostics. Although Taq polymerase is available from several commercial sources, it is crucial and urgent to produce enzymes recombinantly for use in research and diagnostic procedures. To satisfy the demands of industry, it is necessary to maximize and optimize its production. We provide an overview of the recombinant Taq DNA polymerase´s characteristics, structural features, engineering advances, production background and strategies, and purification history in this paper.

The COVID-19 pandemic has highlighted that a subset of survivors, particularly those with severe pneumonia or acute respiratory distress syndrome, develop persistent fibrosis-like lung abnormalities, including reticulation and traction bronchiectasis, often accompanied by impaired gas transfer. Although the clinical course is heterogeneous and many lesions regress over time, longitudinal studies indicate that structural and functional impairment may persist for years in susceptible individuals. Oxidative stress has emerged as a plausible convergent mechanism linking acute epithelial injury, dysregulated inflammatory resolution, and chronic fibrotic remodeling. Reactive oxygen and nitrogen species amplify inflammatory signaling, promote epithelial cell death and senescence, influence macrophage polarization, and activate canonical profibrotic pathways, notably the TGF-β axis. Redox imbalance is embedded within reinforcing circuits involving NOX4-dependent ROS amplification, mitochondrial dysfunction, endoplasmic reticulum stress, inflammasome activation, and senescence-associated secretory programs. Persistent immune activation and organelle stress may sustain redox dysregulation beyond viral clearance, thereby bridging acute lung injury to maladaptive remodeling. This review integrates epidemiological, clinical, and mechanistic evidence to position oxidative stress as a central mediator of post-viral lung fibrosis and discusses therapeutic and translational implications.}, }

Beyond their classical antimicrobial functions, neutrophils can engage in a specialized defense mechanism by releasing web-like extracellular DNA known as neutrophil extracellular traps (NETs). These extracellular traps are a mesh-like network of chromatin DNA decorated with cellular components, including histones, proteases, and antimicrobial enzymes, that function to contain and limit the spread of pathogens. While NET formation contributes to antiviral immunity, accumulating evidence indicates that excessive or dysregulated NET formation can significantly contribute to immunopathology during viral infections. Thus, depending on the context and outcome, NET formation may be viewed as a double-edged sword. Therefore, understanding the regulatory mechanisms governing NET formation and its harmful effects is critical for developing therapeutic strategies that enhance antiviral defense while minimizing tissue damage. In this review, we provide a comprehensive overview of the molecular mechanisms that drive NET formation and clearance, with a particular focus on how viruses modulate these processes to influence disease outcome. We also discuss the pathways underlying NET formation and subsequent neutrophil cell death (NETosis), including canonical and non-canonical pathways, and highlight key signaling axes involving SYK, MAPKs, and NF-κB. Using SARS-CoV-2 and hepatitis B virus as representative models, we examine how different viral components trigger, exploit, or evade NET targeting and how persistent accumulation of NETs can contribute to hyperinflammation, progressive tissue injury, and post-viral syndromes. We further explore emerging evidence linking impaired NET clearance and neutrophil heterogeneity, particularly low-density neutrophils (LDNs), to chronic inflammation and post-viral sequelae such as long COVID and autoimmune hepatitis. Finally, we summarize current and emerging therapeutic strategies aimed at modulating NET formation or enhancing NET clearance.

Redox-responsive nanoparticles (NPs) provide a promising strategy to improve mRNA delivery by undergoing stimulus-triggered disassembly in the reductive cytosol, facilitating efficient mRNA release, endosomal escape, and enhanced translation. This review elucidates emerging structure-function relationships by systematically linking redox-labile chemistries (e.g., disulfide, diselenide, and polysulfide), carrier type, and NP architecture to key biological outcomes, including endosomal escape, redox responsiveness, transfection efficiency, and biodistribution. We further identify critical translational challenges-such as tumor redox heterogeneity, insufficient systematic preclinical evaluation, and manufacturing constraints-and propose actionable strategies, including multi-stimulus-responsive systems, microfluidic and process-analytical manufacturing, and formulation approaches to improve efficacy, reproducibility, and stability. Collectively, these insights provide a practical framework to guide the rational design and clinical translation of next-generation redox-responsive mRNA delivery platforms.}, }

Search terms were "long COVID" and "stellate ganglion block", yielding 45 results. Studies examining patient outcomes after stellate ganglion block were included. Case reports, case series, basic science studies and previous reviews were excluded. Seven studies met inclusion criteria.<br><br>RESULTS: Patients received a single stellate ganglion block in some studies and multiple stellate ganglion blocks in others. All studies reported symptomatic improvement without control groups. Response rates ranged from 55.8% to 100%.

Scientific advances have elucidated mechanisms such as combinatorial receptor coding and signal amplification. This review summarizes these foundations and examines olfactory dysfunction in COVID-19 and Parkinson's disease (PD). In COVID-19, evidence suggests that SARS-CoV-2 targets sustentacular cells rather than olfactory neurons, causing gene downregulation and parosmia attributed to incomplete peripheral filtering, while direct CNS invasion remains rare. In PD, olfactory loss is a prodromal feature. However, seed amplification assays reveal that alpha-synuclein aggregation in the nasal mucosa does not fully correlate with olfactory dysfunction, as reflected by differences between PD and Multiple System Atrophy. This, together with correlations with cardiac sympathetic denervation, challenges simple pathogen propagation hypotheses. We propose that PD-related hyposmia reflects a systemic vulnerability involving deficits in energy metabolism and neural network organization, rather than solely peripheral protein aggregation. Understanding these pathologies requires a multifaceted approach beyond anatomical lesions.}, }

As approximately 6% of people who have experienced acute COVID-19 are estimated to develop PCC, the potential population is vast. Many of the key symptoms of PCC reflect involvement of the nervous system, ranging from cognitive impairment ('brain fog'), headaches and fatigue to anxiety and depression. This Review summarizes the spectrum of neurological and psychological symptoms that occur following acute SARS-CoV-2 infection, with a particular focus on the international consensus-based core outcome set for PCC. We also explore the proposed underlying mechanisms, including evidence for immune system dysregulation, microvascular dysfunction and volumetric changes on neuroimaging. In addition, we review ongoing and completed large-scale treatment trials. Growing evidence suggests a bidirectional interaction between symptoms traditionally considered neurobiological in origin, such as cognitive deficits and headache, and those within the purview of psychiatry, such as anxiety and depression.

Methods: We conducted a systematic review and meta-analysis of nine high-quality studies (n > 400,000 survivors) in accordance with PRISMA 2020 guidelines. Databases including PubMed/MEDLINE and Scopus were searched through January 2026. A quantitative meta-analysis was performed on six studies using a random-effects model to pool adjusted hazard ratios (aHR). Results: The pooled analysis revealed a significant 35% increased risk of new-onset heart failure following COVID-19 recovery (aHR 1.35; 95% CI: 1.14-1.60; p = 0.001). Significant heterogeneity was observed (I[2] = 92.62%), reflecting diverse risk profiles among survivors. The risk was most pronounced in immunocompromised kidney transplant recipients (aHR 2.32) and younger adults under the age of 65 (aHR 1.53). Subclinical myocardial damage, characterized by reduced left ventricular longitudinal strain, was identified even in survivors who experienced mild initial infections.

Nevertheless, clinical use and medico-legal interpretation of placental findings remain inconsistent. To summarize recent evidence on the relationship between placental vascular malperfusion, perinatal mortality and neonatal brain injury, integrating standardized placental pathology with Doppler and angiogenic biomarkers, and to outline the main medico-legal implications. Methods: A PubMed search using the string "((placenta OR placental pathology) AND (stillbirth OR fetal death) AND (maternal vascular malperfusion OR fetal vascular malperfusion))" yielded 118 records. After excluding reviews, meta-analyses, case reports (except one illustrative SARS-CoV-2 placentitis case), non-human studies and papers without original histopathology, 33 studies were included: observational cohorts and case-control studies with standardized placental assessment, autopsy series, biomarker/Doppler cohorts, mechanistic work, one randomized trial protocol and a small number of focused clinical commentaries. Results: Across these studies, MVM emerges as the dominant placental lesion in pre-eclampsia, FGR and a large proportion of stillbirths, especially in early-onset disease and in association with maternal hypertension. FVM is strongly linked to stillbirth and term neonatal encephalopathy, and specific combinations of MVM, FVM and inflammatory lesions correspond to distinct patterns of brain injury. Large population-based cohorts confirm that maternal hypertensive disorders and placental malperfusion are major upstream causes of intrauterine hypoxia and preterm neonatal death. Doppler velocimetry and angiogenic biomarkers (PlGF, sFlt-1 and their ratio) are strongly associated with an increased likelihood of underlying MVM and adverse neonatal outcomes, although their predictive performance remains probabilistic and context-dependent rather than diagnostic. Mechanistic studies suggest roles for placental genomic instability and altered decidual immunity in defective placentation. Conclusions: Maternal and fetal vascular malperfusion represent converging pathways to FGR, stillbirth, preterm neonatal death and neonatal encephalopathy. Routine, standardized placental examination, interpreted together with Doppler and biomarker data, substantially improves causal attribution and timing of injury, with direct consequences for counselling, prevention and medico-legal assessment.}, }

The global healthcare systems have experienced unprecedented challenges in recent years due to COVID-19 pandemic causing widespread disruptions. Delaying TB diagnosis and treatment led to lower reported incidence but could increase mortality, hindering efforts to eradicate TB.

Following PRISMA guidelines, we searched PubMed and Cochrane Library (January 2020-April 2025) for peer-reviewed studies enrolling adults (≥18 years) with polymerase chain reaction (PCR)/antigen-confirmed SARS-CoV-2 infection and reporting cardiac outcomes ≥ 12 weeks post-infection. Eligible outcomes included imaging-based abnormalities (cardiac magnetic resonance [CMR]: T1/T2 mapping, late gadolinium enhancement [LGE]; echocardiography: left ventricular ejection fraction [LVEF], LV/RV strain). Longitudinal trends of biomarkers (troponin, NT-proBNP, C-reactive protein [CRP]) were also studied. Risk of bias was assessed using joanna briggs institute (JBI) tools; synthesis followed synthesis without metaanalysis (SWiM) principles. Fifteen studies (n ≈ 166,000; 14 cohorts, 1 case report) were included. Across CMR cohorts, global systolic function was largely preserved, but tissue abnormalities were frequent early and improved over time: edema indices normalized by ~ 12 months, while LGE prevalence declined (e.g. 50%→19% in paired scans). However, residual non-ischemic scars and elevated T1/T2 persisted in symptomatic subgroups. Echocardiography showed normal LVEF, but subtle left ventricular global longitudinal strain (LV-GLS) impairment versus controls (e.g. -18.5% vs - 19.3%). Biomarker trends were heterogeneous: natriuretic peptide positivity persisted in patients with prior cardiovascular disease (CVD), while troponin and CRP generally normalized. Large population-based cohorts demonstrated sustained 12-month risk for heart failure, myocarditis, and major cardiovascular events, graded by acute severity. Most patients recover gross systolic function, yet subclinical myocardial changes and elevated population-level cardiovascular risk persist up to 1 year. These findings support risk-stratified follow-up, judicious use of advanced imaging, and preventive cardiology strategies.}, }

The aim of this study was to summarize the epidemiological situation of infectious diseases in Poland in 2023. The ongoing impact of the COVID-19 pandemic and the effects of the influx of refugees to Ukraine were taken into account. MATERIAL AND METHODS. We performed a narrative review of studies published in Epidemiological Chronicle, along with data from the national infectious disease registry, Epibaza, which collects data from epidemiological investigations conducted by the State Sanitary Inspectorate. Mortality data were obtained from reports of the Statistics Poland Office. RESULTS. In 2023, 381,244 cases of COVID-19 and 4,329 deaths due to this disease were recorded. The COVID-19 mortality rate in 2023 was several times lower than in 2022, although COVID-19 still accounted for more deaths than other infectious diseases. An "immunity gap" effect was observed following the COVID-19 pandemic, resulting in a significant increase in the incidence of pertussis (2.5 times compared to 2022), influenza and influenza-like illnesses, and intestinal infections (enteric salmonellosis +57.9%, campylobacteriosis +64.1%, yersiniosis +74.5%, norovirus +27.8%). A reduction in the incidence was observed for rotavirus infections, for which routine infant vaccinations were introduced in 2021. The increase in pneumococcal disease incidence occurred mainly in the adult and senior population. While the number of new HIV diagnoses among Polish nationals is increasing, the number of cases among migrants has declined, although they still account for 25% of all new diagnoses. The incidence of other sexually transmitted infections also continues to increase (compared to 2022, gonorrhoea +110.6%, syphilis +89.6%). CONCLUSIONS. For many diseases, incidence increased compared to previous years, for a variety of reasons, including the persistent "immunity gap" following the pandemic and the specific nature of the vaccination program. The impact of the influx of refugees from Ukraine was minor.}, }

Addressing this major public health challenge has been a long-term priority for the European Union, leading to the establishment of the European Reference Networks (ERNs) in 2017.<br><br>MAIN BODY: ERNs are cross-border networks connecting clinical expert centres to share knowledge, improve and harmonise diagnosis and care for patients with rare and complex diseases. Since their inception, 24 ERNs have united 1,606 expert centres across 375 hospitals in all EU Member States and Norway. Their activities span multidisciplinary clinical collaboration, patient-centred governance, education and training, and the development of clinical guidelines. Over 4900 extremely rare or difficult cases have been discussed among experts without requiring the patients to travel abroad when expertise was not available in their own countries. A key factor for this success is the cross-border IT platform - known as the Clinical Patient Management System 2.0 - provided by the European Commission for medical discussions, which enables experts to share patient data, including medical images and lab results, in a secure and protected environment that is fully compliant with all relevant security and data privacy requirements. ERNs have demonstrated resilience in crises such as the COVID-19 pandemic and the war in Ukraine, providing rapid, coordinated responses to sustain care for vulnerable patient groups. The first formal evaluation in 2023 confirmed that more than 95% of member centres met quality standards, underscoring the networks&#x2019; maturity and effectiveness. Moving into the next phase, the Joint Action JARDIN (2024&#x2013;2027) aims to integrate ERNs into national healthcare systems to ensure sustainability and equitable access to high-quality RD care.<br><br>CONCLUSIONS: ERNs exemplify European solidarity and innovation in healthcare, transforming how rare disease expertise is shared and applied across borders. Their continued integration into national systems will be pivotal to achieving a truly cohesive European Health Union that delivers improved outcomes for all patients with rare and complex diseases.}, }

This review combines phenotypic, functional, and transcriptomic findings to explain the disruption of NK cell subsets in COVID-19. Flow cytometry studies have shown generalised lymphopenia and a significant reduction in the CD56bright and CD56[dim]CD16[+] subsets. This change is linked to an increase in the CD56[dim]CD16[-] and CD56[-]CD16[+] populations, which correlate with disease severity. At the molecular level, there is an imbalance between activating and inhibitory receptors. This includes increases in NKG2A, PD-1, and LAG-3, along with decreases in NKp30, NKp46, and NKG2D. These findings are consistent with an exhausted phenotype and weakened cytotoxicity. Single-cell RNA sequencing (scRNA-seq) studies have identified an increase in proliferative, cytotoxic, and platelet-associated CD56[dim] NK subpopulations in severe cases and a reduction of CD56[bright] cells. Transcriptomic profiling showed that upregulation of interferon-stimulated genes (ISGs) and inflammatory pathways driven by STAT1/3, NF-κB activation, and transforming growth factor-beta (TGF-β) signalling suppresses NK effector functions. Collectively, these findings suggest a model in which progressive NK cell dysfunction may be associated with the immunopathogenesis of COVID-19. The integration of multi-omic and phenotypic approaches provides a comprehensive view of NK cell responses to SARS-CoV-2 and suggests potential biomarkers and therapeutic targets to restore NK cell antiviral activity.}, }

This meta-analysis, which searched Web of Science, Embase, PubMed, and Cochrane Library for reports published up to December 25, 2025, aimed to evaluate trends in the prevalence of M. pneumoniae infections across these three periods to guide clinical practice and public health responses. A total of 70 studies were included, and methodological quality was assessed using the Joanna Briggs Institute criteria. The pooled prevalence of M. pneumoniae infections before, during, and after COVID-19 was calculated in R 4.5.0, with Freeman-Tukey double arcsine transformation for extreme proportions. The prevalence of M. pneumoniae infections before COVID-19, during COVID-19, and after COVID-19 was 21.72% (95% CI: 17.09, 26.73), 10.73% (95% CI: 7.57, 14.35), and 28.64% (95% CI: 22.74, 34.93), respectively. Age-stratified analysis revealed the highest prevalence consistently in children > 6 years (pre-pandemic: 46.35%; during-pandemic: 27.32%; post-pandemic: 41.36%) and the lowest in infants < 1 year (8.21%, 4.87%, and 7.81%, respectively). Seasonally, pre-pandemic prevalence peaked in summer (33.34%) and autumn (31.00%). During the pandemic, overall rates declined but remained highest in autumn (15.51%). Post-pandemic, prevalence rebounded broadly, peaking in autumn (37.97%). In conclusion, this study summarises M. pneumoniae trends in children and adolescents before and after COVID-19, indicating a delayed resurgence following the pandemic, and highlights the need for further research to explain these patterns and improve future pandemic preparedness.}, }

Facilitating a pre-emptive transplant is probably one of the most environmentally friendly interventions available in kidney care, as it avoids dialysis, with its requirements for water and energy. However, transplant assessment also requires scrutiny, as it involves a multitude of tests, often with duplication of tests and sometimes with little, if any, evidence (e.g. cardiac testing of asymptomatic patients). Organ retrieval often involves air travel of either the organ or a surgical team, although more innovative approaches, such as drone transport, are being tested. Transplant anaesthesia also has an environmental footprint linked to volatile substances. Surgical tray optimization is well established in other surgical specialties to reduce the effects of repeatedly sterilizing instruments that are only rarely used. Post-transplant patients have a lot of regular blood tests, and it is time we scrutinise those and find a better balance between safe care and environmental footprint. Virtual appointments have become much more common since the COVID-19 pandemic and we should use them where appropriate, for example in long-term care of stable transplant patients. Transplantation is a very research-oriented specialty, and this also has an environmental footprint that is amenable to intervention. In addition, our congresses and conferences have an environmental footprint, and it is for us to promote meetings with just as much learning and interaction but less travel, waste and energy use. The opportunities are there for us to take and our tips provide ideas for clinical teams to turn kidney transplantation into a showcase for excellent, safe and environmentally friendly care in nephrology.}, }

For adolescents and young adults, there were beneficial effects for personal delivery formats (2.13, 1.09 to 4.40), delivery by community members alongside healthcare professionals (6.42, 1.94 to 25.62), and social factors (2.62, 1.45 to 5.04), and negative effects for decision aids (0.43, 0.18 to 0.98) and human versus non-human interaction (0.47, 0.21 to 1.02). For adults, beneficial effects were shown for human interaction (1.86, 1.42 to 2.45), extended opportunities (1.63, 1.35 to 2.00), help with appointment scheduling (1.38, 1.06 to 1.78), payments to cover costs (1.47, 1.03 to 2.16), and motivational interviewing (1.79, 1.21 to 2.64), and there was some evidence for financial incentives (1.15, 0.99 to 1.35) and information on vaccine safety and/or efficacy (1.15, 0.99 to 1.32). For adults, evidence also showed a negative effect of non-human interaction versus no interaction (0.72, 0.57 to 0.92). Subgroup analyses showed variation for underserved populations and in relation to the covid-19 pandemic (before 2020 and 2020 onwards).<br><br>CONCLUSION: Overall, extended opportunities, appointment scheduling help, financial incentives, payments to cover costs, and motivational interviewing were effective content components of interventions to increase vaccine uptake. Effective delivery components overall were human interaction and delivery by community members alongside healthcare professionals. However, effective components varied by age group, for underserved populations, and in analyses investigating the impact of the covid-19 pandemic. These findings have important implications for designing, optimising, and implementing targeted interventions, highlighting which components are effective across different populations and contexts. Consideration of the economic data on interventions should further support resource informed decision making.}, }

Greater awareness of the neurological impact of respiratory viral infections is crucial to improving patient outcomes and mitigating long-term burden of these diseases.<br><br>RECENT FINDINGS: Recent studies have reinforced the association between respiratory viral infections and a broad spectrum of neurological complications. Evidence accumulated during and after the coronavirus disease 2019 (COVID-19) pandemic has expanded this awareness, and emerging data suggest that immune-mediated mechanisms such as glial cell activation, rather than direct viral neurotropism alone, play a central role in CNS injury. Although diagnostic limitations still exist, some advances have been made to increase specificity of resources available for clinicians, particularly PCR and immunologic profiling. Furthermore, vaccination against certain respiratory viruses may reduce the risk of subsequent neurodegenerative disease, highlighting the potential impact of preventive strategies on long-term neurological burden.<br><br>SUMMARY: Establishing causality between respiratory viral infections and subsequent neurological dysfunction remains challenging given the ubiquitous nature of many respiratory viruses and their capacity to cause lifelong latent or persistent infection. Even though some efforts have been made to optimize diagnosis and treatment, addressing these challenges will require further coordinated efforts across clinicians, researchers and healthcare policymakers.}, }

Using the Consolidated Framework for Implementation Research (CFIR) to guide data extraction and thematic synthesis, we examined training programs focused on pandemic preparedness, including design, delivery, implementation processes, and evaluation strategies.<br><br>RESULTS: Thirty-eight studies met inclusion criteria. Training programs varied in scope, format, and target populations, with most focused on COVID-19 and conducted in low- and middle-income countries. Programs commonly emphasized contact tracing, epidemiology, surveillance, and community engagement. While virtual formats increased accessibility, participants often preferred in-person, interactive learning. Facilitators were associated with perceived success included strong partnerships, culturally tailored materials, and improvement through feedback, while barriers were associated with program challenges included limited infrastructure, unclear learning objectives, lack of sustained funding, and inadequate evaluation. Most programs were reactive and short-term, with minimal input from community stakeholders. Trust, equity, and cultural responsiveness emerged as central themes.<br><br>CONCLUSIONS: Preparedness training programs remain fragmented and overly reliant on crisis-driven implementation. Future programs would benefit from prioritizing sustained investment, co-design with community partners, and use of validated frameworks like CFIR to guide development and evaluation.

We describe common themes and highlight unique strategies, providing a foundation for researchers to devise spatial models most appropriate for future pathogens and epidemics. Our review also categorizes the research questions that were addressed with spatial models, highlights parameter estimation techniques, and describes the cyber infrastructure used for model development.<br><br>METHODS: We conducted a systematic review using Web of Science and a standardized set of keywords, followed by thorough examination of abstracts and full texts to determine which studies met our inclusion criteria. To guide our description and comparisons of models, we developed a Geography, Population, Movement (GPM) framework that conceptualizes the interactions between three distinct subcomponents of any spatial model. The geographic model represents the physical arena in which the model is implemented, the intra-population model describes the transmission and disease processes that occur within distinct spatial units of the geography, and the movement model describes the algorithms that dictate how hosts move among spatial units within the geography.<br><br>RESULTS: The search identified a total of 193 articles, of which 109 were included in our review. The most abundant intra-population modeling methods were agent-based (47.7%) and compartmental modeling (29.4%) approaches. Movement models ranged in complexity, with the most complex models implementing commuter movement among many points of interest in the geographic arena, which were sometimes parameterized by fine-scale mobility data. Geographic models ranged from describing microcosms, such as single classrooms, all the way up to multi-country models. Of the 63.3% of models studies that specified the programming language used, we detected ten different languages, with Matlab and Python being the most frequent, although only 30.6% of studies provided open-access code for their models.

The findings demonstrate that psychosocial risks in Latin America constitute a field in consolidation, characterized by the convergence of clinical, labor, and structural dimensions, and by growing regional visibility in the international literature. However, limitations persist, associated with the predominance of cross-sectional studies, the underrepresentation of informal and precarious sectors, and geographical asymmetries in scientific infrastructure.

Global livestock production now exceeds 24 billion animals annually, and pet ownership has risen to over 70% of households in many developed nations, creating unprecedented interfaces for viral exchange. This heightened contact has multiplied opportunities for zoonotic and reverse-zoonotic transmission, as tragically exemplified by the SARS-CoV-2 pandemic. The fecal virome—defined as the totality of viral nucleic acids in the gastrointestinal tract—represents a crucial, yet largely unexplored, pathway for such exchanges. While the bacterial microbiome’s role is increasingly recognized, the virome’s composition, dynamics, and transmissibility between co-habiting humans and animals remain poorly characterized. This review compiles current evidence on the fecal virome of key domestic animals (equines, livestock, pets) and their human contacts under the “One Health” framework. We critically evaluate methodological approaches—from targeted PCR to viral metagenomics—and highlight the discovery of novel viruses and identification of zoonotic agents through metagenomic approaches. Critically, we identify significant knowledge gaps, including the absence of definitive evidence for contemporary cross-species transmission versus shared ancestry or convergent evolution. We propose a strategic research agenda focused on longitudinal studies of human-animal cohorts, standardized metagenomic methodologies, and functional analyses of the virome. Elucidating the fecal virome at this interface is paramount for developing proactive surveillance strategies to predict and prevent the next emerging viral disease.}, }

Eligible studies focused on non-viral nanoparticle platforms for therapeutic, non-infectious mRNA delivery, including applications in protein replacement, genome editing, and immune modulation. Screening yielded 15 studies for inclusion.<br><br>RESULTS: LNPs remain the most clinically advanced platform for therapeutic mRNA delivery. At the same time, polymeric, peptide-based, exosome-inspired, and hybrid nanoparticle systems are expanding the delivery landscape. Emerging RNA formats, including self-amplifying RNA and circular RNA, show potential to prolong expression at lower doses. Clinically, individualized mRNA neoantigen therapy (mRNA-4157/V940) combined with pembrolizumab reduced recurrence risk by approximately 49% in high-risk melanoma in the KEYNOTE-942 phase 2b trial, supporting phase 3 development. In cystic fibrosis, inhaled CFTR mRNA (ARCT-032) advanced to phase 2 after early phase 1 data demonstrated safety and tolerability.<br><br>DISCUSSION: Evidence for non-viral nanoparticle-mediated mRNA therapeutics is strong in preclinical research and increasingly promising in clinical applications beyond vaccinology. While LNPs dominate current translation, alternative carriers and improved RNA formats may broaden tissue targeting and therapeutic durability. Advances in biodegradable ionisable lipids, organ-selective LNPs, and lyophilised or solid formulations are being developed to address persistent delivery and manufacturing constraints. As the field matures, regulatory and policy frameworks will need to align with therapeutic endpoints and support long-term safety monitoring.}, }

Released during necrosis, apoptosis, and neutrophil extracellular trap (NET) formation, histones act as damage-associated molecular patterns (DAMPs), engaging receptors such as Toll-like receptors (TLR2, TLR4, TLR9) to trigger endothelial dysfunction, platelet activation, and cytokine release. Post-translational modifications (PTMs), including citrullination, acetylation, and methylation, further modulate histone immunogenicity, cytotoxicity, and procoagulant potential. These mechanisms amplify thrombin generation, impair anticoagulant pathways, and promote vascular permeability, positioning histones as central drivers of immunothrombosis in sepsis, stroke, ARDS, COVID-19, and autoimmune disorders. Circulating histones and nucleosomes are emerging as biomarkers for disease severity and prognosis.

Severe COVID-19 cases showed elevated IL-6, TNF-&#x3b1;, and IFN-&#x3b3;, while asymptomatic individuals had broader, milder cytokine profiles. Antibody responses were robust across disease severities, with long-lasting IgG activity. Genetic studies identified HLA-B41, B42, C16, and C17 as risk alleles, while HLA-DQB106, DQB103, and B*15 conferred protection. ACE2 polymorphisms including rs2285666, rs73635825 were reportedly prevalent in Africans and were linked to varied ACE2 expression, viral load, and disease severity.<br><br>CONCLUSION: The findings suggest that immune and genetic adaptations in African populations may have modulated susceptibility and severity of SARS-CoV-2 infection outcomes in Africans.<br><br>https://www.crd.york.ac.uk/PROSPERO/view, identifier CRD420251121731.}, }

Validation is achieved by matching model output to detailed viral load trajectories from trials. Antiviral CTS can be applied at all stages of drug development to viruses with distinct shedding patterns. Models can capture the activity of small molecules, neutralizing antibodies, and cellular therapies, as well as combination strategies to enhance potency and avoid drug resistance. Several principles are observed across antiviral CTS models. First, PK and PD models that recapitulate drug levels and concentration-dependent antiviral activity are often necessary, but never sufficient to predict trial results. VID equations are also required to guide optimal treatment timing because expanding immune responses synergistically eliminate infection but are deleterious if too sustained or intense. Therefore, equivalent antiviral doses may have different efficacy if given during different infection stages. Second, antiviral CTS models identify effective plasma drug concentrations in humans, which are often poorly predicted by in vitro assays. Finally, models that do not consider drug mechanisms lead to incorrect efficacy estimates. Data-validated CTS is increasingly used to inform drug dose and dosing interval, treatment timing and duration, virologic endpoint selection, and sample size, particularly when applied to detailed phase 1 and 2 trial data. Given the high expense of antiviral licensure trials, CTS models are vital to optimize trial efficacy and de-risk the drug development process.}, }

The COVID-19 pandemic disrupted healthcare delivery globally, raising concerns that interruptions to routine NCD care could lead to higher morbidity and mortality among populations requiring ongoing care. Although evidence of the pandemic's impact on NCD care has been documented in high-income settings, the experience of SSA health systems, which entered the pandemic with preexisting infrastructure and workforce limitations, remains incompletely understood. This scoping review aimed to systematically map the evidence on COVID-19's impact on NCD care in SSA and to identify service adaptations implemented to maintain care continuity during the pandemic. Studies examining the COVID-19 pandemic and disruptions in NCD screening, diagnosis, or monitoring among adults in SSA were identified from four electronic databases: PubMed/Medline, Scopus, EBSCOhost, and Web of Science. The search strategy combined Medical Subject Headings (MeSH) terms and keywords related to geographic location (SSA), exposure (COVID-19 pandemic and related public health measures), and outcomes (screening, diagnosis, and monitoring of NCDs). Inclusion was limited to original research published between March 2020 and December 2023, written in English, French, or German, and reporting observational data on pandemic-related disruptions to NCD care. Two reviewers independently screened titles, abstracts, and full texts, with data extraction conducted using a standardized form capturing study characteristics, NCD types examined, nature of documented disruptions, and reported innovations. Twenty-eight studies were eligible for inclusion across seven countries in SSA, with the majority of evidence originating from South Africa and Ethiopia. Included studies were mainly retrospective and cross-sectional, with some using mixed-methods and time-series designs, and examined various NCDs, including diabetes mellitus, hypertension, and cancers. Sample sizes ranged from fewer than 100 participants to datasets exceeding 9 million records. Due to the heterogeneity of study designs, populations, and outcomes, findings were synthesized narratively. Six major themes emerged: disrupted access to routine care, interruptions to diagnostics and monitoring, medicine supply chain challenges, adoption of remote care models, health equity impacts, and clinical outcome implications. The pandemic was associated with widespread barriers to healthcare access, diagnostic delays, and medication shortages, with the implementation of innovations such as telemedicine and community-based delivery often hindered by technological and resource limitations. COVID-19 significantly disrupted NCD care across SSA, though health systems demonstrated notable capacity for adaptation, emphasizing the need for resilient service delivery models and equity-focused monitoring to safeguard care during future health emergencies.}, }

In recent years, PF induced by respiratory viral infections has emerged as a forefront topic in respiratory medicine. However, the dynamic regulatory network linking virus-mediated alveolar epithelial injury, aberrant tissue repair, and fibroblast activation remains incompletely understood. This review focuses on representative respiratory viruses-including Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), seasonal influenza viruses, and highly pathogenic avian influenza viruses-and analyzes, from multiple mechanistic dimensions, how viral infection drives the development of PF. The article analyzes how viral infections contribute to tissue damage and functional loss in the lungs via direct host-cell injury, dysregulated immune responses, and disturbances in epigenetic regulation. In particular, the review highlights the aberrant activation of the transforming growth factor-β (TGF-β)/Smad signaling pathway and virus-induced polarization of alveolar macrophages as key processes in the progression of fibrosis. Furthermore, this review systematically summarizes the shared molecular pathways triggered by viral infections in the development of PF and their potential biomarkers, providing a theoretical basis for targeted therapies. In conclusion, respiratory viruses are not only significant etiological factors in PF, but also accelerate the fibrotic process through immune-fibrotic interactions. This review provides a theoretical framework for a deeper understanding of virus-induced PF and outlines directions for the development of targeted therapies and clinical intervention strategies.}, }

It analyzes traditional approaches such as inactivated and attenuated vaccines in conjunction with innovative technologies, including subunit, viral vector-based, DNA, mRNA, and virus-like particle (VLP) vaccines. Furthermore, novel strategies to enhance vaccination efficacy, including nanoparticle-based and plant-derived vaccines, are examined.

Shortcomings in modern AI include limited training data modalities (i.e., types of input data used for model training), reliance on offline training, and the use of static models. This scoping review provides an overview of evidence that uses AI methods applied to youth mental health (YMH) and provides an assessment of the current state of research that integrates multimodal AI (i.e., models that incorporate multiple data modalities) and/or online learning (i.e., incremental or continual model training from streaming data) for the diagnosis, monitoring, and treatment of YMH-related problems. The findings indicate that research in AI applied to YMH is limited in the areas of multimodal AI and online learning. The number of studies in this field is steadily growing. Studies incorporating online learning demonstrate that this approach enhances model performance and adaptability, which is crucial for developing translational models capable of addressing real-world challenges effectively. Despite these advances, key challenges remain, including the availability and long-term validity of multimodal data, the lack of participant-related information in certain databases and studies, the ethical and logistical difficulties of collecting data from minors, and the computational costs of training robust AI models.}, }

The vaccine cold chain is a complex, highly specialised, temperature controlled supply chain network that extends from the point of vaccine manufacture to dose administration, and has multiple points of vulnerability. Large quantities of vaccines are lost because of excess heat or accidental freezing, resulting in missed opportunities for vaccination. Disruption to the provision of routine vaccines during the covid-19 pandemic resulted in millions of children not being vaccinated. The vaccine cold chain needs strategic prioritisation for investment and innovation so that the next generation of vaccine cold chains for low and middle income countries can be designed towards providing reliable and sustainable vaccine security in an uncertain world of climate change, managing the advent of new vaccine technologies, and narrowing inequalities in global health for resource poor communities.

Although vaccines and repurposed antivirals have reduced disease severity, the continued emergence of SARS-CoV-2 variants and breakthrough infections underscores the need for sustained discovery of novel therapeutics. The main protease (Mpro), an essential and highly conserved enzyme required for viral replication remains a validated and attractive antiviral target. Medicinal plants represent a vast and underexplored source of structurally diverse bioactive compounds with antiviral potential; however, traditional plant-based drug discovery approaches are often constrained by reliance on ethnobotanical knowledge and fragmented screening workflows. This review critically examines emerging strategies that integrate machine learning, LC-MS-based metabolomics and network pharmacology to modernise medicinal plant-based antiviral discovery. We highlight how machine learning enables data-driven prioritisation of candidate compounds and plant species beyond well-studied taxa, while metabolomics provides experimental validation through comprehensive chemical profiling and dereplication. Molecular docking and molecular dynamics further refine candidate selection by evaluating binding modes and stability, whereas network pharmacology offers systems-level insight into multitarget and multipathway effects. Importantly, we discuss key limitations of these approaches, including data bias, model interpretability, and gaps between in silico prediction and experimental validation. By synthesising these methodologies into a unified computational-experimental pipeline, this review provides a critical framework for accelerating the discovery of plant-derived Mpro inhibitors and supports the development of resilient antiviral strategies for current and future pandemics.}, }

It analyses leadership, patient recruitment, and how HIC-based technologies and laboratory platforms shape research agendas. Many influential trials are conceived and sponsored by HIC institutions, with recruitment concentrated in LMICs because of higher disease burden, larger eligible populations and lower costs. Meanwhile, LMIC centers report growing readiness to support randomized controlled trials, and LMIC-conceived, led and completed multicentre studies are increasingly reported. Ongoing concerns include misalignment between donor priorities and national agendas, inequities in authorship and leadership, and ethical challenges related to standards of care, post-trial access, consent and compensation. The review compares regulatory, consent and insurance processes in India and the United States, and highlights enabling factors such as harmonised guidelines, global registries, political goodwill and professional networks.

However, the COVID-19 pandemic has understandably raised concerns among lactating mothers and pregnant women regarding the risks of infection and vaccine safety. Therefore, it is essential to carefully evaluate the potential dangers of COVID-19 transmission within this vulnerable population especially when considering vaccination for pregnant and breastfeeding women. Encouragingly, the United States Food and Drug Administration has granted approval for the use of two COVID-19 vaccines namely, Pfizer-BioNTech COVID-19 and Moderna COVID-19 to contain the spread of the COVID-19 virus. Both vaccines have been approved for administration in pregnant and breastfeeding women, providing much-needed reassurance to those with concerns about vaccine safety. It is important to recognize that the benefits of vaccination for both the mother and the infant far outweigh the risks associated with COVID-19 infection. Therefore, lactating mothers should view vaccination as a vital measure to protect themselves and their infants from the virus. In addition to elaborating on the successes of safety and effectiveness, this review is unique that it also includes current and newly updated evidence published between 2020 and 2025, comprehensively discussing on several newer vaccine platforms together with recent viral variants.

Still, lifelong immunosuppression leaves recipients vulnerable to opportunistic viral infections, which can lead to severe complications such as graft dysfunction and post-transplant lymphoproliferative disorder. With emerging viral threats such as SARS-CoV-2 and arboviruses, alongside persistent challenges posed by CMV, EBV, and BKV, this review is timely in addressing the evolving landscape of post-transplant viral infections and their management. Recent studies highlight how immunosuppression impairs both innate and adaptive antiviral defenses, including diminished toll-like receptor signaling, dysfunction of NK cells, and disrupted T- and B-cell responses. Viruses exploit these deficits through immune evasion strategies, such as MHC-I downregulation and the production of immunosuppressive microRNA. Advances in management include antiviral prophylaxis, adoptive T-cell therapy, and immune monitoring, with emerging therapies like virus-specific T-cell infusions and complement inhibition showing promise. The findings underscore the need for personalized, organ-specific approaches to post-transplant care. Enhanced surveillance, vaccination strategies, and novel immunotherapies are critical in mitigating viral risks. Future research should focus on immune-risk stratification and the development of an adaptable therapeutic approach to enhance transplant outcomes in the face of evolving viral threats.}, }

A 52-year-old Asian woman exhibited generalized myoclonus, ataxia, nystagmus, and dysarthria two weeks after a fever episode, which deteriorated rapidly within a few days. Electromyography (EMG) revealed synchronized bursts in both hands concurrent with myoclonic jerks. The absence of somatosensory evoked potential and lack of correlation between electromyography (EEG) and EMG suggested a subcortical origin of the myoclonus. A post-infectious immune-mediated process was considered the most likely mechanism, given the latency from fever to myoclonus onset, and the absence of other possible etiologies. Treatment with intravenous methylprednisolone led to notable improvement and a good outcome at the two-month follow-up.<br><br>CONCLUSION: Myoclonus arising from subcortical structures can be associated with COVID-19.

In multidisciplinary settings, medical imaging has a role in diagnosing, assessing severity, monitoring progress and delineating anatomical structures involved in diseases. Imaging also helps to elucidate models of disease pathogenesis. In this review, imaging features of COVID-19 lung disease are analysed in the context of pathophysiological processes in different phases of the disease. Radiological evidence is presented for the central role of vasculopathic phenomena in both the acute and post-acute phases of COVID-19. From the outset of the COVID-19 pandemic, a lack of formal collaborative interdisciplinary systems to build models of pathophysiology led to widespread misunderstanding of the lung disease. Specifically, the lack of a systematic multidisciplinary approach to share concepts relating to radiological evidence with collaborators from other medical and scientific fields led to the use of terminology which was, and remains, potentially inappropriate or misleading. In conclusion, imaging is essential to multidisciplinary understanding of COVID-19 vascular pathophysiology. Current evidence should lead to adapted diagnostic guidelines for long COVID. Formation of collaborative systems to build interdisciplinary understanding of disease pathogenesis across all medical and scientific specialties should be a priority at the outset of any future pandemic.}, }

Given their diverse roles, it is not surprising that approximately 5% of genes in eukaryotic cells are involved in lipid biosynthesis pathways. The multifunctional nature of lipids also makes them attractive targets for pathogens, including viruses, as cellular lipids are involved in and manipulated throughout every stage of viral replication. In the initial phase of replication, viruses exploit existing cellular lipids for entry and trafficking. After the replication is established and viral proteins are processed, extensive reprogramming of lipid synthesis and redistribution supports viral replication, assembly, and other processes. This review focuses on how coronaviruses, especially severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), utilize different lipid species and related cellular enzymes to interfere with lipid dynamics and functions and how this affects the different stages of coronaviral replication in vitro.

Self-amplifying RNA encodes a replicase that amplifies intracellular RNA templates, enabling high antigen expression at substantially lower doses than non-replicating mRNA. Circular RNA has a covalently closed topology that confers resistance to exonucleases and supports sustained translation through cap-independent initiation. The evidence base remains asymmetric: saRNA has progressed through multiple human studies, including phase 3 evaluations of COVID-19 vaccines, and has received regulatory authorization in several jurisdictions, whereas circRNA vaccines remain largely preclinical, with limited publicly available human data.

Since its first description in Japan in 2009, C. auris has spread rapidly worldwide, with a marked acceleration following the coronavirus disease 2019 (COVID-19) pandemic. As of December 2025, 84,941 colonization or infection cases have been reported across 82 countries spanning 6 continents. In this review, we summarize the current knowledge of the biology and global epidemiology of C. auris. We first examine its taxonomy, proposed origins, and key biological, genetic, and phenotypic characteristics, with particular emphasis on factors underlying environmental persistence, transmission dynamics, antifungal resistance, and virulence. Drawing on published literature and publicly available surveillance data from national public health authorities worldwide, we provide an updated overview of the global epidemiological landscape and evolving transmission patterns of C. auris. Finally, we discuss potential strategies to mitigate the continued and escalating global spread of this emerging multidrug-resistant fungal pathogen.}, }

In developing countries, especially in Africa, tuberculosis is the leading cause of pericarditis, often associated with HIV. Diagnosis is based on clinical criteria, such as chest pain and electrocardiographic changes, and it can be supported by imaging studies such as echocardiography, cardiac magnetic resonance imaging, and computed tomography. Identification of etiology is crucial to personalized treatment, although the specific cause is often unidentified.

The pathological mechanisms underlying severe COVID-19, along with the relationship to neurological disorders and potential risk for neurodegeneration, remain poorly understood. The aim of this narrative review is to summarize neuropathological features described in postmortem human COVID-19 brains (n = 352). Furthermore, analysis of biofluids and neuroimaging from PASC patients underline long-term changes in the proteome and CNS response following the infection. Postmortem brain studies from severe COVID-19 patients highlight disruption of the fluid-brain barriers and vascular dysregulation defined by endothelial inflammation and disruption, hemorrhages, and hypoxic-ischemic damage. Neuroinflammation, including astrogliosis, microglia nodules and infiltration of adaptive immune cells, has been reported in the olfactory bulb, medulla oblongata, midbrain and cerebellum. Neuronal damage was demonstrated in the hippocampus, midbrain and cerebellum in severe COVID-19 and protein aggregation was observed in the midbrain and entorhinal cortex. Neuropathological burden and elevated blood and/or cerebrospinal fluid (CSF) levels of proinflammatory cytokines (e.g. IL-6) and neuro-axonal proteins (e.g. NfL) correlated with severity of anosmia, memory deficits, and cerebellar ataxia. Elderly patients and/or patients with underlying neurological diseases were more susceptible and had worsened symptoms. Potential disease mechanisms underlying neurological symptoms observed in severe COVID-19 are vascular and fluid-brain barrier abnormalities, chronic neuroinflammation, persistent axonal damage and protein aggregation. In PASC patients, an altered biofluid proteome with increased neuronal proteins and pro-inflammatory cytokines was observed. The pathological burden in affected brain regions may contribute to manifestations such as anosmia, memory deficits, and cerebellar ataxia.}, }

The goal of this study was to systematically review and evaluate the literature on rural US adolescent social media use. Specifically, what is known about their social media use, amount and type of use, and the associations between social media use and health outcomes.<br><br>METHODS: A systematic search was conducted on seven databases: PubMed, CINAHL, SCOPUS, PsycINFO (ProQuest), Web of Science, Embase, and Google Scholar. Studies were eligible for inclusion if they sampled rural US populations, sampled adolescents (ages 10&#x2013;19), and had at least one of the following as an outcome: how much adolescents use social media, how adolescents are using social media including content, and/or whether social media use was associated with a health outcome.<br><br>RESULTS: A total of 34 articles matched the inclusion criteria and were included in analysis (N&#x2009;=&#x2009;22,315). Results suggest that rural US adolescents use social media to the same extent as non-rural adolescents. Rural adolescents with marginalized identities rely on social media to form connections with those with shared identities outside of their geographic area. Social media also fostered an environment for harmful connections, as numerous studies reported cyberbullying. In respect to mental health, using social media was found to be an avenue for coping with anxiety during the COVID-19 pandemic; however, increased time spent on social media did not reduce existing feelings of nervousness, anxiety, depression, or stress in the pandemic. Interventional studies indicated that social media was successfully used as a tool to disseminate health information and provide support to marginalized groups amongst the already hard-to-reach population of rural adolescents.<br><br>CONCLUSIONS: This systematic review highlights the lack of research dedicated to social media use amongst rural US adolescents, despite high prevalence of use.

The review is based on the World Health Organization building blocks to look at the strategic changes that have led to measurable gains in the health of Rwandan people. Good centralized leadership and control have been key to this accomplishment. This made it possible to decentralize service delivery, build excellent health information systems, and invest money in the health workforce. A key part of the transformation is universal health coverage (UHC), especially mutuelle de santé, which increased coverage from 27% in 2004 to more than 85%, hence cutting down out of pocket costs, which improved equity. Integration and use of community health workers (CHWs) have been instrumental in expansion of primary care to the population mostly in rural settings, improving maternal and child life, tuberculosis (TB) treatment through direct observed therapy (DOT), and disease surveillance. These coordinated actions have resulted in substantial reductions in mortality from infectious diseases (HIV/AIDS, TB, and malaria), maternal and child health indicators, and the gradual integration of services for noncommunicable diseases and mental health. Rwanda's health system was stress tested and proved its effectiveness in the COVID-19 and Marburg outbreaks, proving exceptional planning and rapid response capacities. Despite Rwanda's achievement, obstacles still persist, such as reliance on foreign funds, limited human resources lowering the quality-of-service delivery, and mental health challenges still in existence. Rwanda's experience illustrates that a proactive government, citizen participation, and research-based innovation may produce rapid and significant overall health gains, providing a valuable model for similar situations to other countries.}, }

To address these challenges, the present research synthesis is the first to use a comprehensive collection of representative individual participant data from international large-scale assessments. This analysis incorporated cumulative evidence from 1980 to 2022, including 452 probability samples from 90 countries, and covered student and adult populations. The meta-analytic average correlation between math anxiety and math achievement was r = -.26. Moderator analyses revealed novel evidence that this relationship is sensitive to both construct characteristics and individual and contextual factors. Specifically, the negative relationship was weaker for the worry facet of math anxiety compared to its affective and cognitive interference facets, and it was weaker following the onset of the COVID-19 pandemic in 2020. Additionally, the negative relationship was stronger for individuals with average and high levels of math achievement and in countries with higher gross domestic product per capita. Gender differences in the relationship were largely negligible after 2010, although female individuals exhibited a stronger negative relationship in the 1980s and 1990s than male individuals.

My research has sought to elucidate the principles by which the host organism senses, integrates, and regulates responses to viral stress, spanning molecular to organismal levels. Key discoveries include the identification of ACE2 as the functional receptor for SARS-CoV and a critical regulator of disease severity; elucidation of innate-immune overactivation ("cytokine storm") as a driver of fatal pathology; identification of lipid-mediated RNA regulation that restrains excessive inflammation; and discovery of neuro-immune and epigenetic mechanisms linking acute infection to long-term dysfunction. These findings reveal infection as a multi-layered biological reprogramming process involving immunity, metabolism, the nervous system, and chromatin architecture.

This narrative review critically synthesizes current evidence on miRNA dysregulation across the acute and post-acute phases of COVID-19, highlighting their pathogenic roles, clinical relevance, and existing knowledge gaps. During acute infection, altered miRNA profiles-including those associated with immune activation, endothelial dysfunction, and immunothrombosis-reflect both host responses and viral strategies of immune modulation, including miRNAs carried by extracellular vesicles (EVs) and SARS-CoV-2-derived v-miRNAs. In LC, emerging data suggest that persistent miRNA alterations are associated with unresolved inflammation, pulmonary dysfunction, neurological symptoms, and vascular injury, although available studies remain limited and heterogeneous.

Environmental TCS levels have increased significantly following the coronavirus disease 2019 pandemic, posing a potential threat to humans and ecosystems. Epidemiological investigations and toxicological studies have shown that long-term TCS exposure can damage human tissues and organs and induce neurodevelopmental disorders in offspring. However, studies on the mechanisms underlying its neurotoxicity and toxicity risk assessments are limited. This review summarizes the status of environmental and human TCS exposure and systematically outlines its neurotoxic effects. To further elucidate the mechanisms underlying TCS neurotoxicity, using TCS-induced attention-deficit hyperactivity disorder (ADHD) as an example, we constructed an adverse outcome pathway (AOP) framework based on a systematic toxicology approach. We found that TCS increased the expression of cannabinoid receptor 1, which activates the "neuroactive ligand-receptor interaction" pathway, leading to ADHD-like behaviors, including cognitive, learning, and memory deficits, by modulating chemical synaptic transmission and neurotransmitter levels. The AOP framework was further used to assess the associated neurodevelopmental toxicity risks of TCS, contributing to a better understanding of its characteristics and safety. Thus, future research on the mechanisms underlying TCS toxicity and issues related to its detection and regulation should be emphasized.}, }

These are generally high-volume surgical procedures, such as cataract surgery, hip replacement, and knee replacement. Elective surgery waiting times challenge the clinical application of the bioethical principles of beneficence, nonmaleficence, autonomy, and justice. Extensive waiting may prolong time to benefit or even lead to harm. Moreover, failure to receive timely care runs counter to patients' autonomous wishes to be treated without delay. Finally, different principles of distributive justice are likely to contradict each other under the conditions of restrained access to care that exist when patients must wait for care. It is essential to ensure that patients on waiting lists receive fair access to health care services.<br><br>CONCLUSION: This analysis indicates that long waiting lists potentially violate three of the four basic biomedical principles proposed by Beauchamp and Childress. The fourth principle, justice, is also challenged and remains to be analyzed in reference to underlying ethical principles. From an ethical perspective, waiting lists create accountability at the governmental, institutional, and physician levels, although not to an equal degree.}, }

This meta-analysis synthesized the available comparative clinical evidence on the safety and efficacy of MSCs in patients with moderate to critical COVID-19 and examined the reported outcomes relevant to Long-COVID.<br><br>METHODS: We searched the PubMed, Embase, and CNKI databases for original, comparative studies in moderate, severe, or critical COVID-19 published up to September 2, 2024. Twenty-four eligible studies (13 RCTs and 11 non-randomized controlled trials; n&#x2009;=&#x2009;1080) were included in the mortality meta-analysis. Patients were assigned to either the intervention group (MSC therapy plus standard care) or the control group (standard care with or without placebo). The primary efficacy outcome was all-cause mortality, while the primary safety outcomes were adverse events (AEs) and serious adverse events (SAEs). Secondary outcomes included clinical recovery, hospitalization metrics, chest imaging, and inflammatory biomarkers. We performed a pooled meta-analysis on mortality with subgroup analyses (by disease severity, administration route, dosing frequency, and study design), assessment of publication bias (using funnel plots and Egger's test), and evaluation of the quality of evidence via the GRADE approach. AEs/SAEs were analyzed using meta-analysis and descriptive statistics, while other secondary outcomes were summarized descriptively.<br><br>RESULTS: MSC therapy significantly reduced all-cause mortality (MSC: 26.4% vs control: 31.9%; fixed-effect OR&#x2009;=&#x2009;0.74, 95% CI 0.55-0.99), with low heterogeneity (I[2]&#x2009;=&#x2009;2.8%, P&#x2009;=0.422[Q-test]) and no publication bias. The quality of evidence was moderate (according to the GRADE assessment). The subgroup analysis revealed a significant survival benefit in severe/critical patients (OR&#x2009;=&#x2009;0.73, 95% CI 0.54-0.98) but not in studies that included moderate cases (OR&#x2009;=&#x2009;0.91, 95% CI 0.23-3.65). No significant heterogeneity was found across study designs, administration routes, or dosing frequencies, which confirmed the robustness of the primary findings while indicating insufficient evidence to determine the optimal regimen. The secondary outcomes suggested improvements in clinical recovery, pulmonary function, and pro-/anti-inflammatory cytokine balance in patients that received MSC therapy. Limited studies with long-term follow-up indicated potential benefits for Long-COVID outcomes (e.g., fatigue, quality of life, residual CT abnormalities, and exercise tolerance). No significant differences were observed in AEs or SAEs post-MSC infusion, which suggested that MSC therapy was well tolerated.<br><br>CONCLUSION: This meta-analysis indicated that MSC therapy may reduce mortality in patients with severe or critical COVID-19, demonstrating a favorable safety profile and potential benefits for Long-COVID and other viral pneumonias. Further large-scale, rigorous RCTs and mechanistic studies are warranted to strengthen the evidence base and standardize MSC administration regimens (source, dosing, frequency, and intervals) for managing COVID-19, Long-COVID, and other viral pneumonias.}, }

This review integrates core analytical frameworks-sequence alignment and genome annotation; maximum-likelihood and Bayesian phylogenetic/phylodynamic inference; codon-based selection and recombination analyses; and AI-assisted structural prediction combined with deep mutational scanning (DMS)-to convert viral sequences into mechanistic and predictive insight. We emphasize how global surveillance ecosystems (GISRS, GISAID, and Nextstrain) and sustained regional programs reveal genotype turnover, antigenic drift, and seasonality in RSV, HPIV, norovirus, and SARS-CoV-2, enabling near real-time lineage tracking and vaccine-strain deliberation. Mapping positively selected residues and recombination breakpoints onto three-dimensional protein structures clarifies immune escape in key surface glycoproteins (e.g., RSV F/G, HPIV HN/F, norovirus VP1) and strengthens genotype-phenotype interpretation. Comparative reinfection patterns-lifelong immunity in measles versus recurrent RSV/HPIV infections-illustrate how evolutionary rate and antigenic constraint shape population immunity and control strategies. Despite major advances, progress remains constrained by geographic sampling bias, incomplete metadata, uneven computational capacity, and uncertainties in molecular clocks, recombination inference, and machine-learning predictions. The field is now moving toward predictive virology, integrating AI-enabled structural modeling, mutational fitness landscapes, and clinical-immunological metadata within real-time analytical platforms to anticipate immune-escape trajectories. Prioritizing pediatric respiratory pathogens alongside influenza and coronaviruses, and reinforcing equitable data-sharing and governance, will be essential for globally inclusive, forward-looking viral surveillance and intervention.}, }

This review examines the epidemiological trends, diagnosis, treatment, impact of COVID-19, and economic burden associated with thyroid cancer in the Philippines. We conducted a literature search in Scopus and HERDIN to synthesize the existing data on the epidemiology, diagnosis, and management of thyroid cancer in the Philippines. Filipinos exhibit a higher prevalence of BRAFV600E mutations, and thyroid cancer is more common among females and older individuals. Diagnostic procedures include risk assessment, family history evaluation, neck examination, hormone tests, neck ultrasonograms, thyroid scans, and biopsies guided by the Bethesda System. Treatment primarily involves surgery, which is determined by risk classification and disease extent. Total or near-total thyroidectomy is recommended for most cases, followed by postoperative management tailored to individual patient factors. Anaplastic thyroid cancer may require multimodal approaches. The COVID-19 pandemic disrupted healthcare access, leading to delays in thyroid cancer treatment and challenges in monitoring, prompting the adoption of telemedicine. However, the pandemic's psychological impact on thyroid cancer survivors is concerning. The economic burden remains substantial despite health insurance programs. In conclusion, thyroid cancer in the Philippines necessitates enhanced prevention, early detection, determination of risk factors, risk stratification, and treatment strategies. The COVID-19 pandemic emphasized the need for adaptable healthcare systems. This study summarized the epidemiology, diagnosis, and management of thyroid cancer in the Philippines. Implementation of existing policies and further research on the Filipino population is vital to address this growing health concern and ensure improved outcomes for thyroid cancer patients.}, }

While acute COVID-19 is generally milder in children due to a more robust innate immune response, the mechanisms driving the persistence of symptoms in PPCC remain incompletely understood and likely multifactorial. This narrative review synthesizes current epidemiological data and explores the "perfect storm" of immunological and pathophysiological alterations underpinning the condition. We examine critical hypotheses including a dysregulated immune response characterized by altered T-cell subsets, monocyte activation, and autoantibody production. We discuss the potential role of persistent SARS-CoV-2 viral reservoirs in "sanctuary sites" like the gastrointestinal tract and the reactivation of latent viruses such as Epstein-Barr virus (EBV). Furthermore, the review details downstream pathogenic pathways, including vascular endothelial inflammation (thrombo-inflammation), neuroinflammation, and metabolic dysfunctions affecting the mitochondria and tryptophan-kynurenine pathway. Finally, we address the role of microbiome dysbiosis in perpetuating systemic inflammation and the gut-lung axis dysfunction. Given the heterogeneity of clinical presentations, we conclude that PPCC is likely a syndrome of overlapping biological phenotypes. Future research must prioritize identifying these specific biological endotypes to develop targeted diagnostic and therapeutic strategies for the pediatric population.}, }

Although most cases are considered idiopathic, external triggers that can disrupt immune tolerance have been described. Vaccination has been discussed as a potential precipitating factor in autoimmune skin diseases. However, the relationship between vaccination and the induction of pemphigus-related autoantibodies has not been comprehensively summarized. Methods: We conducted a narrative review of all available studies published in the last 25 years identified through medical databases, excluding studies on COVID-19 vaccinations. Reports describing either new-onset pemphigus or exacerbation of preexisting pemphigus with a temporal association to vaccination were included. Clinical characteristics, vaccine type, latency period, direct immunofluorescence findings, and ELISA results for desmoglein autoantibodies were analyzed. In addition, we present our own clinical-laboratory experience illustrating this issue. Results: The current evidence consists predominantly of case reports and small case series. Published cases describe pemphigus vulgaris and pemphigus foliaceus occurring after vaccinations against influenza, hepatitis B, tetanus, diphtheria, pertussis, rabies, and other routinely administered immunizations. The latency period most often ranged from several days to a few weeks. Immunopathological findings were consistent with classical pemphigus diseases, including intercellular IgG deposits in the epidermis and circulating autoantibodies against desmoglein 1 and/or desmoglein 3. Our patient was a 78-year-old woman who developed cutaneous form of pemphigus vulgaris, diagnosed with direct immunofluorescence (DIF) and multiplex ELISA, 10 days after diphtheria-tetanus-pertussis vaccination. The patient had a positive family history of autoimmune blistering disease, namely mucous membrane pemphigoid. Conclusions: Based on the currently available evidence, a direct causal relationship between vaccination and pemphigus diseases cannot be established. Nevertheless, accumulated clinical and serological observations suggest that vaccination may act as a triggering factor in genetically or immunologically predisposed individuals, possibly by amplifying pre-existing subclinical autoreactive immune responses. Further population-based and mechanistic studies are required to clarify this association, while the overall benefits of vaccination remain substantial.}, }

A substantial proportion of adults worldwide are infected with all three viruses and may experience concurrent herpesvirus latency, yet they have largely been studied independently. This review examined whether latent and intermittently reactivating herpesviruses share overlapping inflammatory signatures and whether their combined presence contributes to chronic inflammatory burden. Methods: A narrative integrative review was conducted using MEDLINE, Embase, and Google Scholar (inception-October 2025). Evidence from thirty-one cohort studies and mechanistic investigations spanning virology, immunology, neurology, and clinical medicine was synthesized. Results: Herpesvirus reactivation rates ranged from 23% in general Intensive Care Unit (ICU) populations to 85% in severe COVID-19. Concurrent reactivation of multiple viruses occurred in 34-63% of critically ill patients and was associated with worse clinical outcomes. Notably, simultaneous CMV and EBV reactivation independently predicted mortality (adjusted hazard ratio, 3.17; 95% CI, 1.41-7.13). Across infections, overlapping inflammatory biomarkers, including IL-6, TNF-α, CRP, and PGE2, were consistently elevated, reflecting convergent activation of IFN and NF-κB signaling pathways. Mechanistic studies suggest cross-compartment immune priming, where CMV-driven T-cell exhaustion facilitates EBV reactivation, and viral cytokine signaling enhances HSV-associated neuroinflammation. Conclusions: HSV, EBV, and CMV triple latency may represent an underrecognized contributor to chronic inflammation in immunocompetent hosts.

Clarifying the magnitude of risk, clinical course, and recovery-relative to myocarditis following SARS-CoV-2 infection-is essential for risk-benefit assessment and public health guidance. Methods: We performed a systematic PubMed and Embase search (January 2020-December 2024) and synthesized cohort, registry, and surveillance data on myocarditis incidence and outcomes following mRNA COVID-19 vaccination. Outcomes included incidence, observed-to-expected (OE) or incidence rate (IRRs) ratios, hospitalization, and short-term recovery. Study selection followed PRISMA 2020 systematic review guidelines. Results: Myocarditis following mRNA COVID-19 vaccination was identified as a rare adverse event, most commonly occurring after the second dose and in younger male individuals. Across multiple cohort and registry-based studies, cases were generally mild and self-limited, with most patients recovering without complication. In contrast, myocarditis following SARS-CoV-2 infection was consistently associated with more severe outcomes, including higher rates of hospitalization and mortality. Conclusions: Vaccine-associated myocarditis is rare, typically mild, and self-limited, with excellent short-term recovery; vaccinated individuals also exhibit lower odds of in-hospital death and intubation. In contrast, infection-associated myocarditis is more frequent and severe. Overall, the benefit-risk profile of mRNA vaccination remains strongly favorable.}, }

Despite the development of novel drugs and vaccines, clinical outcomes remain suboptimal for vulnerable populations, including the elderly and those with comorbidities or compromised immunity. Tea polyphenols, a class of structurally diverse and bioactive nutraceuticals, may modulate viral entry, replication, and host inflammatory pathways implicated in disease progression through pleiotropic effects on viral attachment, membrane fusion, intracellular replication, and proteolytic processing. Here, we provide an updated chemo-biological perspective on the antiviral and immunomodulatory mechanisms of tea polyphenols against SARS-CoV-2. Current evidence highlights their potential to serve as promising candidates for further mechanistic and translational investigation as adjunctive strategies and nutraceuticals for COVID-19 management.

Some factors, such as psychological and social barriers, can negatively impact views on vaccines and can contribute to vaccine hesitancy. The primary objective of this structured literature review is to investigate the available evidence relating to factors affecting vaccine hesitancy within several countries in Southeastern Europe.<br><br>METHODS: An electronic database search was conducted to identify studies assessing the public and healthcare professionals' (HCPs) attitudes towards vaccination in Southeastern Europe. These searches were supplemented with grey literature searches. Included studies were conducted in Bulgaria, Croatia, Romania, Serbia, and Slovenia between 1 January 2012 and 31 December 2022.<br><br>RESULTS: Of the 35 studies identified from the database searches, the most prominent theme observed across Romania, Croatia, and Bulgaria was low confidence in COVID-19 vaccines. Across all age groups, COVID-19 vaccine confidence in these regions was highly dependent on whether individuals thought vaccines were safe and effective, as well as their general trust in vaccines. Confidence in COVID-19 vaccines was seen as relatively high, with attitudes towards routine and elective vaccines being generally positive amongst the general public and HCPs, in Romania, Croatia, Serbia and Slovenia. However, uncertainty around the effectiveness of the vaccine still exists. In Bulgaria, trust in routine and elective vaccines remained low in the general public. Complacency and financial constraints were also identified as underlying causes of vaccine hesitancy.<br><br>CONCLUSIONS: The main cause behind vaccine hesitancy in several countries in Southeastern Europe is distrust in vaccine effectiveness and safety. These key findings can be utilised to support evidence-based decisions regarding where to focus resources to improve public and HCP perception of vaccines in Southeastern Europe.}, }

This study conducted a scoping review of the effects of respiratory vaccines in older adults with cardiovascular disease. Methods: We included studies evaluating adults aged ≥ 60 years with cardiovascular disease who received different types of respiratory vaccines. Eligible designs comprised clinical trials, observational cohort studies, and other relevant studies. Editorials, commentaries, and non-original publications were excluded. A comprehensive and targeted literature search was conducted in PubMed, Scopus, EMBASE, and Web of Science from database inception through January 2026. Results: A total of 25 studies were included, encompassing 1,782,787 adults aged ≥ 60 years with cardiovascular disease who received various respiratory vaccines. RSV vaccines were associated with a lower incidence of cardiorespiratory hospitalization and stroke among vaccinated individuals. Pneumococcal vaccines showed that sequential dual vaccination strategies were associated with a lower risk of cardiovascular events. Influenza vaccination was associated with improved cardiovascular outcomes, lower mortality, and reduced adverse events. COVID-19 vaccines were associated with reductions in mortality and hospitalizations. These benefits are particularly relevant in an older population with a high burden of comorbidities; therefore, complete vaccination schedules, including booster doses, should be considered a central strategy for prevention and comprehensive management in this high-risk group. Conclusions: Vaccination against respiratory viruses in older adults with cardiovascular disease demonstrates an overall favorable/acceptable profile of efficacy and safety, with reductions in mortality, hospitalizations, and cardiovascular events, without a significant increase in serious adverse events.}, }

Unlike traditional vaccine platforms, mRNA vaccines depend on highly specialized raw materials, including plasmid DNA (pDNA), nucleotides, enzymes, and lipid nanoparticles (LNP), that are produced by a limited number of global suppliers. These dependencies, combined with platform-specific manufacturing processes and stringent cold chain requirements, introduce vulnerabilities across production, distribution, and regulatory oversight. This narrative review examines the distinctive features of mRNA vaccine supply chains and identifies key challenges and opportunities across three interconnected domains: manufacturing systems, logistics and distribution, and regulatory governance. Drawing on literature published between January 2021 and March 2026, the review synthesizes evidence on supply chain bottlenecks revealed during the COVID-19 pandemic, including upstream raw-material dependencies, limitations in manufacturing scale-up, cold chain constraints, and regulatory fragmentation. Particular attention is given to the implications of these challenges for low- and middle-income countries, where infrastructure, technical capacity, and regulatory resources may limit participation in mRNA vaccine production and deployment. The review also highlights emerging strategies to strengthen supply chain resilience, including diversification of input suppliers, development of regional manufacturing hubs, improvements in vaccine thermostability, regulatory harmonization initiatives, and the use of digital technologies for supply chain management. By integrating insights from manufacturing, logistics, and regulatory perspectives, this study contributes to a better understanding of the structural characteristics shaping mRNA vaccine supply chains and identifies priority areas for strengthening global preparedness for future health emergencies.}, }

These autoantibodies are directed against various receptors in the autonomic and cardiovascular systems, including those targeting proteins of the renin-angiotensin system (RAS). The RAS plays a central role in regulating vascular homeostasis, inflammation, and endothelial function. During SARS-CoV-2 infection, the interaction of the spike (S) protein with angiotensin-converting enzyme 2 (ACE2) can alter the balance of the RAS, favoring an imbalance towards the ACE/Angiotensin II/AT1R axis, known for its pro-inflammatory, pro-thrombotic, and vasoconstrictive properties. Similar pathological mechanisms also come into play in response to vaccinations that use the S protein as an antigen. Studies conducted by other groups and us on patients with PACS and PACVS have revealed the presence of autoantibodies directed against these RAS components and the mechanisms by which these antibodies can worsen the clinical situation. In particular, anti-ACE2, presumably formed by the anti-idiotype network or molecular mimicry, is correlated with PACVS symptoms in many patients. Furthermore, the presence of anti-MAS1 antibodies can reduce the efficiency of the ACE2/Angiotensin-(1-7)/MAS1 axis, which normally acts as a counter-regulator. Considering this evidence, an analysis of RAS molecules and the autoantibodies implicated in reactions to them may be useful for evaluating a state of persistent dysregulation associated with post-vaccination symptoms such as asthenia, headache, skin edema and bruising, cardiovascular alterations, and neurovegetative manifestations. Finally, we offer insights into diagnosing these multifaceted syndromes and working hypotheses to guide research into possible therapeutic approaches.}, }

This review consolidates current understanding of SARS-CoV-2 viral structure, receptor biology, and the gestational regulation of key entry cofactors, including ACE2, TMPRSS2, NRP1, CTSL and FURIN, within reproductive and placental tissues. The review further integrates documented mechanisms of cytokine-mediated immune dysregulation, endothelial injury, thrombo-inflammation, and steroidogenic alteration observed in affected pregnancies, and examines their contribution to placental malperfusion, preeclampsia-like presentations, fetal growth abnormalities and preterm birth. Published molecular and computational studies characterising trophoblast antiviral defenses, receptor expression patterns, and structural determinants of Spike-ACE2 affinity are synthesised to contextualise the biological basis of placental susceptibility and the rarity of confirmed transplacental transmission. Current evidence on maternal clinical outcomes, fetal and neonatal consequences, vaccination efficacy, therapeutic considerations and contemporary management guidelines is also critically reviewed. By integrating molecular, immunological, pathological and clinical insights, this article provides a comprehensive framework for understanding the interaction between SARS-CoV-2 infection and pregnancy-specific physiology, with implications for risk assessment, preventive strategies and maternal-fetal care.}, }

FIP is now a treatable and frequently curable disease. In these revised guidelines, the European Advisory Board on Cat Diseases (ABCD) presents an update on the treatment of FIP, incorporating the findings of new studies including the range of available treatments (such as GS-441524, remdesivir and molnupiravir (EIDD-2801) and its active metabolite EIDD-1931), which varies globally, as well as suggestions for monitoring and prognostic indicators. Tables are used to present easy-to-find information on antiviral and supportive treatments for cats with FIP. GS-441524 is the most extensively studied antiviral for FIP with treatment success rates often exceeding 90%. Remdesivir is primarily reserved as an injectable antiviral for severely affected cats unable to tolerate oral medication; it is usually replaced by oral medication as soon as, and when, possible.

The clinical spectrum is heterogeneous, involving respiratory, cardiovascular, neurological, renal, gastrointestinal, and endocrine systems, thereby posing substantial diagnostic and therapeutic challenges. Despite extensive investigation, the precise immunopathogenic mechanisms underlying LC remain incompletely defined. Accumulating evidence suggests that LC is driven by a multifactorial interplay of persistent viral antigen reservoirs, chronic immune activation, dysregulated innate and adaptive immune responses, autoimmunity, endothelial dysfunction, microvascular injury, and aberrant tissue repair. These systemic immune perturbations manifest variably across different organs, contributing to the diverse clinical phenotypes observed. However, mechanistic clarity is hindered by heterogeneity in study designs, limited longitudinal data, and the absence of standardized immunological profiling.

While these platforms can foster connection, learning, and entertainment, concerns have grown about their potential to influence mental, physical, and social well-being. Research on this topic has expanded rapidly over the past decade, yet much of it remains cross-sectional, limiting insights into long-term outcomes. Longitudinal studies are essential to capture evolving patterns of digital engagement, identify causal relationships, and guide effective policies and interventions that support youth in navigating digital environments. In particular, evidence is needed to distinguish between beneficial and harmful forms of digital engagement, such as social connection versus problematic use, and to understand how these impacts differ across diverse populations and contexts. The COVID-19 pandemic further accelerated young people's technology use, underscoring the urgency of examining both risks and opportunities. This review, therefore, synthesizes longitudinal research to map trends, identify knowledge gaps, and inform future directions.<br><br>OBJECTIVE: The study aimed to systematically identify and map longitudinal studies examining associations between everyday digital technology use (eg, social media, gaming, and internet use) and the health and well-being of youth (25 years or younger) and to chart the types of evidence available by technology category, outcomes, and geographical setting in order to highlight key gaps for future research.<br><br>METHODS: A systematic search of PubMed, Embase, and PsycArticles (2014-2024) was conducted and reported in accordance with PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews). Data extraction covered demographics, digital technology categories, and health outcomes.

Internet use (n=201 studies), social media (n=140 studies), and gaming (n=83 studies) dominated the themes. Mental health was the most frequently assessed outcome, with a focus on anxiety and depression. Geographically, 15% (40/267) of studies originated from low- and middle-income countries, with the majority from high-income settings such as the United States (n=76 studies) and Australia (n=15 studies).

We also identify major gaps in surveillance systems, research capacity, prevention, and clinical management across the region. Sub-Saharan Africa is experiencing one of the fastest global increases in diabetes, with the highest proportion of undiagnosed cases and a projected steep rise in intermediate hyperglycaemia and diabetes by 2050. Urbanisation, ageing, obesity, and lifestyle transitions are major contributors; however, a substantial proportion of type 2 diabetes occurs in lean individuals (BMI <25 kg/m[2]), particularly in rural settings, suggesting distinct metabolic and developmental pathways not captured by models derived from high-income countries. Bidirectional interactions between diabetes and malaria, tuberculosis, HIV, or COVID-19 make disease trajectories complex. Persistent gaps in surveillance, a reliance on modelled estimates, low genomic representation, and constrained access to modern diabetes medications hinder progress.

Despite ongoing surveillance, advances in molecular diagnostics, and research on vaccines and therapeutics, sporadic zoonotic spillovers and healthcare-associated outbreaks still occur, showing that current prevention strategies are still not enough. This review compiles current evidence from epidemiological studies, camel reservoir research, genomic monitoring, and public health reports published between 2012 and April 2025 to identify the key gaps preventing effective containment. Special focus is given to recent genomic discoveries, including post-2022 clade B sublineages, recombination events, and spike protein changes that might affect transmission and the effectiveness of countermeasures. Available data suggest that MERS-CoV epidemiology is driven by repeated camel-to-human transmission, followed by occasional amplification in healthcare settings rather than sustained community spread. High seroprevalence and frequent detection of viral RNA in juvenile camels, seasonal gathering in markets, and extensive animal movement networks contribute to ongoing viral circulation at the animal-human interface. Genomic studies consistently show close phylogenetic relationships between camel and human isolates, confirming recurrent zoonotic transmissions. However, fragmented surveillance systems, delayed genomic data integration, inconsistent biosecurity practices, and limited field evidence for camel vaccination pose major barriers to control. Additionally, hospital outbreaks continue to occur due to delayed diagnosis, overcrowding, and incomplete adherence to infection-prevention protocols, underscoring the need for improved clinical preparedness. Based on the integrated synthesis of epidemiological, veterinary, and genomic evidence, this review proposes an implementation-focused One Health genomic framework tailored to the Saudi context. The proposed roadmap highlights real-time connection of human and camel surveillance, expands genomic sequencing capacity, targets vaccination strategies in camels and high-risk human populations, standardizes biosecurity measures in markets and abattoirs, and strengthens infection control systems in healthcare facilities. Alignment with national governance structures and Saudi Vision 2030 offers a practical pathway for coordinated multi-sectoral action. This review concludes that MERS-CoV is unlikely to be eradicated soon, but it can be effectively managed through a genomics-enabled, operational One Health approach that combines surveillance, vaccination, clinical preparedness, and policy coordination. The model outlined here provides a scalable way to reduce zoonotic spillover risk and strengthen readiness against future coronavirus and emerging zoonotic threats.}, }

This qualitative review of peer-reviewed literature, government reports, and community-led research identified five interconnected themes: (1) community partnerships; (2) Pacific-centred approaches; (3) clear and trusted communication; (4) digital inclusion and literacy skills; and (5) economic support and sustainability. From these themes, key enablers were identified, which included community leadership, trusted communication strategies, and agile local systems, alongside barriers such as underinvestment, digital exclusion, reliance on unpaid labour, and limited inclusion of Pacific leadership in early planning. The findings highlight that Pacific-led systems are not supplementary but an essential public health infrastructure. Embedding these approaches within national emergency planning, through sustainable funding, formal governance roles, and strengthened digital inclusion, offers a pathway to a more equitable, trusted, and resilient pandemic response.}, }

As of early 2026, the global landscape is dominated by highly evolved sublineages of the Omicron (B.1.1.529) variant, including the JN.1-descendent subvariants NB.1.8.1 and XFG. This review provides a comprehensive overview of the molecular mechanisms driving viral fitness, with a primary focus on the structural transformations within the spike (S) protein's receptor-binding domain (RBD), N-terminal domain (NTD), and S2 subunit. We examine the biophysical impacts of pivotal mutations, such as E484 K, K417 N, and F486P, alongside the phenomenon of convergent evolution and epistatic compensation. Furthermore, we provide an integrated analysis of current knowledge regarding the evolving dynamics of humoral and cellular immunity, exploring the challenges posed by immune imprinting and the decline of neutralizing antibody titers against antigenically distant strains. A comparative discussion of SARS-CoV-2 and seasonal influenza highlights divergent evolutionary paces but converging regulatory frameworks for annual vaccine updates. Finally, the current status of next-generation vaccine platforms is evaluated, specifically mosaic nanoparticles and mucosal delivery systems, which aim to provide pan-sarbecovirus protection and interrupt transmission. These insights are integrated into a policy framework focused on annual strain selection and enhanced genomic surveillance for sustainable long-term pandemic management.}, }

Autophagy is an intracellular catabolic pathway involving lysosomal degradation and is closely associated with immunological pathways, effectively combating bacterial, viral, fungal, and parasitic infections. Accumulating evidence suggests that autophagy activation or inhibition by natural products promotes antimicrobial responses against various pathogens. Numerous natural products can modulate autophagy through diverse signaling pathways, suggesting their potential as a host-directed therapeutic strategy that may complement conventional drug regimens or help mitigate drug resistance in various infectious diseases. However, it remains largely unclear whether these effects are mediated by direct modulation of autophagy or indirectly through associated mechanisms, including enhanced immune defense, attenuation of pathological inflammation, or crosstalk with other organelle functions. Additionally, multiple pathogens can evade host responses; thus, autophagy activation may inadvertently create favorable conditions for certain pathogens. This review discusses the current knowledge of natural products in terms of their antimicrobial actions through autophagy regulation, particularly the roles of distinct natural product classes, such as polyphenols, alkaloids, terpenoids, quinones, peptides, and macrolides in modulating autophagy for potentially contributing to control various infectious diseases. Exploring the intricate molecular interplay between natural products and autophagy in limiting infections may provide valuable insights that could inform the development of innovative host-directed antimicrobial treatments based on autophagy regulation.Abbreviations: 3-MA: 3-methyladenine; AM: alveolar macrophages; AMP: antimicrobial peptides; AMPK: 5' adenosine monophosphate-activated protein kinase; ARDS: acute respiratory distress syndrome; ART: artemisinin; ASFV: African swine fever virus; ATG: autophagy related; AZM: azithromycin; BafA1: bafilomycin A1; BECN1: beclin 1; BMDM: bone marrow-derived macrophage; BNIP3: BCL2 interacting protein 3; BNIP3L: BCL2 interacting protein 3 like; CALCOCO2/NDP52: calcium binding and coiled-coil domain 2; CAMKK2: calcium/calmodulin-dependent protein kinase kinase 2; CBD: cannabidiol; CF: cystic fibrosis; CGA: chlorogenic acid; CGAS: cyclic GMP-AMP synthase; CHUK/IKKα: component of inhibitor of nuclear factor kappa B kinase complex; CLP: cecal ligation and puncture; CLR: clarithromycin; CMA: chaperone-mediated autophagy; CoV: coronavirus; DHT: dihydrotanshinone I; EGCG: epigallocatechin-3-gallate; EIF2A: eukaryotic translation initiation factor 2A; EIF2AK2: eukaryotic translation initiation factor 2 alpha kinase 2; ESKAPE: Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter spp.; ESRRA: estrogen related receptor alpha; FOXO1: forkhead box O1; FUNDC1: FUN14 domain containing 1; HBV: hepatitis B virus; HCV: hepatitis C virus; HDT: host-directed therapy; HIV: human immunodeficiency virus; HMGB1: high mobility group box 1; HSV: herpes simplex virus; IAV: influenza A virus; ICT: isocryptotanshinone; IFN: interferon; IKBKB/IKKβ: inhibitor of nuclear factor kappa B kinase subunit beta; IL: interleukin; INH: isoniazid; IRF3: IFN regulatory factor 3; KEAP1: kelch like ECH associated protein 1; LAMP: lysosomal associated membrane protein; LAP: LC3-associated phagocytosis; LPS: lipopolysaccharide; MAP1LC3/LC3: microtubule associated protein 1 light chain 3; MAPK: mitogen-activated protein kinase; MDM: monocyte-derived macrophage; MDR: multidrug-resistant; MON: monotropein; Mtb: Mycobacterium tuberculosis; MTOR: mechanistic target of rapamycin kinase; mtROS: mitochondrial ROS; NET: neutrophil extracellular trap; NFE2L2/Nrf2: NFE2 like bZIP transcription factor 2; NFKB/NF-κB: nuclear factor kappa B; NLRP3: NLR family pyrin domain containing 3; NLRX1: NLR family member X1; NOTCH1: notch receptor 1; NTM: nontuberculous mycobacteria; OMS: ohmyungsamycin; PAK1: p21 (RAC1) activated kinase 1; PINK1: PTEN induced kinase 1; PKM/PKM2: pyruvate kinase M1/2; PLD: phospholipase D; PM: peritoneal macrophage; PPM1A: protein phosphatase, Mg2+/Mn2+ dependent 1A; PRKN/parkin: parkin RBR E3 ubiquitin protein ligase; PtdIns3K: phosphatidylinositol 3-kinase; PtdIns3P: phosphatidylinositol-3-phosphate; PTEN: phosphatase and tensin homolog; RB1CC1/FIP200: RB1 inducible coiled-coil 1; RELA/p65: RELA proto-oncogene, NF-kB subunit; RIF: rifampicin; ROS: reactive oxygen species; RSV: resveratrol; RUBCN/rubicon: rubicon autophagy regulator; SAR: selective autophagy receptor; SIRT: sirtuin; STING1: stimulator of interferon response cGAMP interactor 1; STX17: syntaxin 17; Tat: trans-activator of transcription; TB: tuberculosis; TBK1: TANK binding kinase 1; TFEB: transcription factor EB; TLR: toll like receptor; TNA: tanshinone IIA; TNF: tumor necrosis factor; UA: ursolic acid; ULK1/Atg1: unc-51 like autophagy activating kinase 1; UPR: unfolded protein response; UVRAG: UV radiation resistance associated; VAMP8: vesicle associated membrane protein 8; VDR: vitamin D receptor; WIPI2: WD repeat domain, phosphoinositide interacting 2; ZFYVE1/DFCP1: zinc finger FYVE-type containing 1; ZIKV: Zika virus.}, }

Nonetheless, challenges like stigma, lack of access, and resource limitations persist. The Biopsychosocial Model remains central to social psychiatry, offering an integrated framework that considers biological, psychological, and social dimensions. This comprehensive perspective ensures that interventions target not only symptoms but also contextual factors contributing to mental illness. The future of social psychiatry will be shaped by heightened awareness of social determinants, particularly amid global crises like war or COVID-19. Consistent application of the biopsychosocial model in clinical settings is essential. Policy advocacy focused on housing, employment, and inclusive care-alongside cultural sensitivity and the use of digital tools-will be vital.

In humans, these systems reach exceptional regulatory sophistication and are coordinated through integrated immunological and hemostatic mechanisms forming the frontline of defense. While highly efficient under physiological conditions, these networks can become dysregulated when challenged by overwhelming pathological stimuli. The COVID-19 pandemic exemplified these vulnerabilities, revealing profound inter-individual variability in immune activation that shaped susceptibility, disease progression, and outcomes. Similar variability extends to autoimmune disorders, cancer, and neurodegenerative diseases, where immunity and hemostasis govern detection, response, and chronicity. Artificial-intelligence models now propose an "immunological age," reflecting cumulative immune behavior and predictive disease risk. Nevertheless, pathologies may escape immune-hemostatic control and become refractory to therapy, leading to severe complications or fatal outcomes, as emphasized previously. This review synthesizes current understanding of the molecular, cellular, and systemic interplays linking immunity, inflammation, hemostasis, fibrinolysis, and RAAS. We highlight how these interdependent pathways shape disease expression across infections, autoimmunity, sepsis, malignancy, and cardiometabolic syndromes. In addition, we examine emerging laboratory biomarkers, such as NETs, Annexin A1, micro-RNAs, sACE2, and procoagulant platelets, that now provide unprecedented insights into immunothrombosis and thrombo-inflammation.

However, broader application remains limited by severe toxicities, reduced efficacy toward solid tumours, and the high cost and complexity of ex vivo manufacturing. The autologous nature of most current therapies contributes to variable product quality, lengthy vein-to-vein times, and restricted patient access. In vivo CAR-T therapy has emerged as a potential solution, aiming to generate functional CAR-T-cells within the patient, with several platforms progressing into early Phase I clinical trials. This approach eliminates reliance on patient-derived starting material, reduces manufacturing failure rates, and offers the prospect of off-the-shelf availability at lower cost. Central to in vivo CAR-T development is selecting an appropriate gene delivery platform. Viral vectors, including lentiviral, adenoviral, and adeno-associated viral systems, have an established role in ex vivo CAR-T manufacturing and in vivo gene therapies. Non-viral vectors, such as lipid nanoparticles (LNP) and polyplexes, have garnered increasing attention due to their high packaging capacity, potential for redosing, and validation in large-scale production, as exemplified by mRNA-LNP vaccines against COVID-19. Recently, the in vivo CAR-T engineering toolbox has expanded with DNA-based LNP platforms capable of stably integrating CAR transgenes via transposon systems, fourth-generation T-cell-targeted lentiviral systems that minimise CAR display on vector particles and aberrant splicing, and emerging genome-editing technologies. This review compares viral and non-viral vectors for in vivo CAR-T therapy, evaluating their relative advantages and limitations in terms of safety, efficacy, scalability, analytical methods, regulatory implementation and commercial feasibility.}, }

It is characterized by the delayed and persistent exacerbation of symptoms following even mild physical or cognitive activities. This review presents a systematic review of the pathophysiological mechanisms involved in PEM, proposing a dynamic framework of multi-system interactions that may lead to homeostatic imbalance. The etiology of PEM is multifactorial, potentially involving factors such as the persistent presence of pathogens, exposure to environmental toxins, and genetic predisposition. Collectively, these factors may establish a vulnerable baseline that heightens the body's physiological response to stressors, such as exercise, potentially triggering a pathological reaction. First, mitochondrial dysfunction and metabolic abnormalities may act as potential initiating factors in PEM, manifesting as impaired ATP synthesis, overproduction of reactive oxygen species (ROS), and the accumulation of metabolic byproducts. It is crucial to emphasize that exercise itself induces a 'toxic excitatory effect,' whereby healthy individuals enhance mitochondrial function and antioxidant defenses through physical activity. However, in individuals predisposed to PEM, due to underlying pathological conditions (e.g., sequelae of viral infections), this adaptive process is disrupted, preventing effective restoration of mitochondrial homeostasis and may initiate a potential vicious cycle of dysfunction. Second, ROS and mitochondrial DNA (mtDNA), as damage-associated molecular patterns (DAMPs), along with pathogen-associated molecular patterns (PAMPs), may activate the NLRP3 inflammasome and induce the release of pro-inflammatory cytokines such as IL-1β, IL-6, and TNF-α, potentially transforming localized metabolic stress into a systemic inflammatory response. Subsequently, peripheral inflammation may be transmitted to the central nervous system through disruption of the blood-brain barrier and vagal nerve pathways, activating glial cells and initiating neuroinflammation. This process may ultimately affect the brain's interoceptive network, particularly the insular cortex, resulting in altered perception and processing of signals related to fatigue and pain. Furthermore, mitochondrial dysfunction in neurons may contribute to central energy depletion, which may impair synaptic plasticity and induce cognitive deficits and brain fatigue. Ultimately, this review proposes that PEM may arise from a complex interplay among mitochondrial dysfunction, immune activation, and neuroinflammation, which together form a self-perpetuating loop of "energy exhaustion - inflammation amplification," potentially contributing to the chronic and multi-system nature of PEM symptoms. The integrated "metabolism-immune-neuro" interaction model presented in this article may provide a potential comprehensive framework for understanding PEM and highlights the need for a multi-target, collaborative intervention approach that may help disrupt the pathological cycle.}, }

Many Black people quickly succumbed to Coronavirus Disease 2019 (COVID-19). This paper describes systemic trauma as a lens to conceptualize the effects of COVID-19, racial stress and trauma, and grief. A recount of the events during the year 2020 is reviewed. Racism towards Black people was at an all-time high. Complicated and collective grief was ever-present. As a by-product of COVID-19, economic and health disparities resurfaced to further complicate Black people's well-being. Systemic trauma is described as a comprehensive and inclusive framework that captures the intensity and depth of the trauma Black Americans experienced. We argue that culturally appropriate interventions are needed to help Black people continue to heal from the distress of 2020. Race-informed trauma treatment is a culturally appropriate intervention that facilitates healing, improves the quality of life, and fosters posttraumatic growth for Black Americans. We offer race-informed treatment as a theoretical orientation that can facilitate healing and posttraumatic growth for Black people.}, }

This review aimed to describe published studies in Africa that have utilized ES for the detection of infectious pathogens of public health importance in Africa. The study employed a rapid review approach to synthesize evidence on ES of infectious pathogens in Africa, following guidance from the Cochrane Rapid Reviews Methods. Articles from major databases, including Scopus, PubMed, Science Direct, and Cochrane, were screened using Catchii.org. Duplicates were removed, and data were extracted into Excel, and study quality was appraised using the AXIS tool and a modified Newcastle-Ottawa Scale. The search strategy identified 2,189 articles, of which 90 were found to be eligible. We identified 47 microbial species that have been reported across studies. These consisted of 46.8% bacteria (n = 22), 36.2% viruses (n = 17), 4.3% fungi (n = 2), and 12.7% parasites (n = 6). Among viruses identified, SARS-CoV-2 was the most common, followed by rotaviruses and polioviruses. Vibrio cholerae was mostly reported among bacterial pathogens. The most common sampling method was grab sampling (n = 85, 94.4%), while two-phase separation (n = 22, 37.3%) and filtration (n = 11, 39.3%) were the most frequently used concentration methods for viral and bacterial detection, respectively. ES of infectious pathogens in Africa remains limited. There is a need to expand this to enhance pathogen monitoring, transmission insights, and preparedness for emerging variants.}, }

During the COVID-19 pandemic, SARS-CoV-2-associated myelopathy emerged as a rare para- or postinfectious cause of myelitis. The pandemic coincided with a decline in enterovirus outbreaks and acute flaccid myelitis, which are now re-emerging, underscoring the importance of epidemiologic surveillance. Metagenomic next-generation sequencing is useful in suspected infectious myelopathy because it can identify unexpected pathogens from cerebrospinal fluid, but its imperfect sensitivity and contamination risk mean it should complement rather than replace conventional testing. Growing recognition of compartmentalized central nervous system inflammation and cerebrospinal fluid viral escape in HIV myelopathy has shifted management toward antiretroviral resistance patterns and treatment optimization. Therapeutic advances remain limited and largely pathogen-specific, although targeted approaches such as mogamulizumab for HTLV-1-associated myelopathy are promising.<br><br>SUMMARY: Recent progress in infectious myelopathies has been driven by improved pathogen detection and more tailored diagnostic strategies, although treatment advances are beginning to emerge.}, }

In septic patients, rhIL-7 significantly increased ALC (MD&#x202f;=&#x202f;1.33&#x202f;at 3 weeks; 95% CI [0.29, 2.38]; MD&#x202f;=&#x202f;1.14&#x202f;at 4 weeks; 95% CI [0.02, 2.25]), CD4[+] T-cell counts (MD&#x202f;=&#x202f;0.56&#x202f;at 3 weeks; 95% CI [0.08, 1.05]) and CD8[+] T-cell counts (MD&#x202f;=&#x202f;0.40&#x202f;at 2 weeks; 95% CI [0.05, 0.76]). However, rhIL-7 failed to reduce mortality (RR&#x202f;=&#x202f;1.01; 95% CI [0.36, 2.81]) or the incidence of secondary infections (RR&#x202f;=&#x202f;1.05; 95% CI [0.48, 2.30]) in patients with sepsis. In patients with COVID-19, rhIL-7 did not significantly increase ALC at 30 days (MD&#x202f;=&#x202f;0.46; 95% CI [-0.15, 1.08]) or reduce mortality (RR&#x202f;=&#x202f;0.85; 95% CI [0.55, 1.33]), but it did significantly reduce the incidence of secondary infections (RR&#x202f;=&#x202f;0.58; 95% CI [0.46, 0.74]; p&#x202f;<&#x202f;0.0001). A combined analysis revealed that rhIL-7 significantly increased ALC (MD&#x202f;=&#x202f;1.15&#x202f;at 3 weeks; 95% CI [0.47, 1.84]; MD&#x202f;=&#x202f;0.80&#x202f;at 4 weeks; 95% CI [0.24, 1.36]) and reduced the risk of secondary infections (RR&#x202f;=&#x202f;0.64; 95% CI [0.50, 0.81]), but had no effect on mortality or ICU length of stay.<br><br>CONCLUSION: RhIL-7 effectively ameliorates sepsis-associated lymphopenia but does not improve prognosis.

Plate removal is not routinely conducted in the UK. A 2019-2020 meta-analysis reported a 13.4% removal rate, though regular audits are uncommon. This study evaluates whether audit of local plate removal rates against established benchmarks merits encouragement. A retrospective review was conducted of orthognathic surgery at a tertiary centre (2014-2024). Procedures included Le Fort osteotomy, bilateral sagittal split osteotomy (BSSO), bimaxillary osteotomy (BIMAX), genioplasty, and other mandibular osteotomies. All patients received two postoperative doses of dexamethasone and intravenous antibiotics. Data collected included demographics, smoking status, surgical site, re-plating, and antibiotic use. The primary outcome was return to theatre (RTT) for plate removal or replacement. Chi squared, Fisher's exact, and binomial tests were used to assess statistical significance. Over 10 years, 417 patients underwent 429 orthognathic procedures, including 12 revisions to achieve the desired skeletal and orthodontic outcome. Overall, metalwork removal/adjustment occurred in 46 cases, predominantly within the first year, with infection identified as the leading cause. The removal rate was 10.7% (46/429), consistent with the 13.4% benchmark (p = 0.12). Yearly rates generally aligned with the benchmark, except in 2021, when deviations were likely to have been influenced by COVID-19-related disruptions. Smoking (p = 1.0) and oral antibiotics on discharge (p = 0.09) were not significantly associated with plate removal rates. These findings validate the 13.4% benchmark for metalwork removal. Routine audit and inter-unit collaboration are vital for refining benchmarks and improving patient care.}, }

The COVID-19 pandemic showcased the power of viral kinetics surveillance and modelling; however, our understanding of viral kinetics has been limited to retrospective analyses, convenience samples and bespoke models. To strengthen responses to ongoing and emerging outbreaks, we argue that viral kinetics should be a core component of pathogen surveillance. Building upon insights gained during the COVID-19 pandemic, we review ways that continuous viral kinetic surveillance supports infectious disease response by informing epidemiological parameters, development and deployment of therapeutics, and adaptive policy design. To achieve this, various challenges must be addressed regarding data standards, study design and communication. We advocate for the creation of a global, living library of viral kinetics data, with associated data sharing standards, modelling toolkits and on-demand epidemiological reports. Successfully integrating viral kinetics into active disease surveillance efforts will support both active outbreak response and improve the knowledge base vital for pandemic preparedness.

Many observational studies examined antidiabetic medications use and COVID-19 outcomes. Meta-analyses showed that insulin was linked to worse outcomes, while metformin, sodium-glucose cotransporter 2 (SGLT-2) inhibitors, and glucagon-like peptide-1 (GLP-1) agonists were associated with better outcomes. Findings on dipeptidyl peptidase-4 (DPP-4) inhibitors, pioglitazone, and sulfonylureas were mixed-showing neutral, beneficial, or negative effects. However, randomized controlled trials (RCTs) testing these medications after SARS-CoV-2 infection found no effect on COVID-19 outcomes, implying that their anti-inflammatory effects do not translate into meaningful clinical benefits during acute infection. This discrepancy prompts questioning what observational studies actually measured. Given that many studies applied robust statistical methods, their results are unlikely solely due to confounding or indication bias. We hypothesize that these studies reveal broader cardiovascular effects and illuminate diabetes management more than they inform COVID-19 pathology. Their findings align with current 2022 American Diabetes Association/European Association for the Study of Diabetes (ADA/EASD) consensus guidelines for the management of type 2 diabetes mellitus endorsing metformin, SGLT-2 inhibitors, and GLP-1 agonists as first-line therapies, recommending cautious early insulin use, and reserving DPP-4 inhibitors, sulfonylureas, and pioglitazone for selective cases. This is applicable regardless of COVID-19 status. Further research should determine whether infection-related clinical endpoints, such as mortality or hospitalization from COVID-19 or other infections, might serve as valid surrogate markers for cardiovascular outcomes.}, }

Integrating digital health as part of hybrid care models is essential in designing care pathways that can adapt to different contexts, including future health crises. Although a comprehensive search was conducted, the heterogeneous reporting of care modifications may have influenced the interpretation of the findings. In the future, research may expand the application of hybrid care models to innovative strategies for effective crisis management.}, }

This study investigates the persistence of enveloped viruses, particularly SARS-CoV-2, in three key environments: air, surfaces, and wastewater, with a focus on hospital settings. We present a systematic review of the literature on the environmental persistence of these viruses, complemented by a case study conducted in two reference hospitals in northern Iran. A total of 72 wastewater samples, 46 air samples, and 92 surface samples were collected from COVID-19 wards and analyzed using RT-PCR for the presence of viral RNA. Results indicate notable viral persistence, with detection rates of 21.74% in air samples, 26.09% in surface samples, and 63.89% in wastewater samples. This indicates substantial viral shedding from infected patients, particularly in influent samples, where treatment inefficiency contributed to higher detection. It is important to note that RT-PCR detects viral RNA, which does not necessarily indicate infectivity; however, its presence highlights routes of potential transmission and the need for vigilant environmental management. The findings highlight the critical need for enhanced environmental monitoring and the strict implementation of effective disinfection protocols to mitigate the risk of viral transmission in healthcare settings. The persistence of SARS-CoV-2 in hospital environments underscores the importance of addressing fomite transmission and optimizing ventilation strategies. Overall, this comprehensive approach provides valuable insights into the behavior of enveloped viruses in diverse settings and emphasizes the necessity of integrated surveillance strategies to aid infection control efforts and protect public health.}, }

Here, we advance a perspective that Extracellular Vesicles (EVs) act as active mediators bridging SARS-CoV-2 infection and neurodegenerative processes. As nanoscale messengers capable of crossing the blood-brain barrier, EVs can transmit post-viral signals and orchestrate multi-target gene regulation in recipient cells through their microRNA (EV-miRNA) cargo. Our integrative analysis suggests that EV-miRNAs dysregulated in acute COVID-19, Alzheimer's Disease (AD), and Parkinson's Disease (PD) converge on pathways governing neurovascular integrity, redox and metabolic homeostasis, and neuronal proteostasis. We propose that sustained dysregulation of these interconnected modules-driven by EV-mediated signalling-may underlie the perpetuation of neuro-PASC and accelerate neurodegeneration in susceptible individuals. Viewing EVs as mechanistic agents that both transmit and amplify pathogenic cues reframes them as actionable targets for intervention and risk stratification. This perspective calls for translational frameworks that leverage EVs to illuminate, predict, and modify the trajectory of post-viral neurodegeneration.}, }

Diabetic patients are predisposed to both superficial as well as invasive fungal disease, and account for substantial morbidity and mortality. Recent pandemic of COVID-19 underlined the global problem of mucormycosis, however, the burden of fungal infections among diabetics has a much broader horizon. This review aims to summarise the spectrum of fungal infections encountered among diabetic patients, along with elucidating immunopathogenesis and clinical challenges encountered in diagnosis and management of such infections.<br><br>METHODS: We conducted a narrative review of all published literature focusing on spectrum of fungal infections, immunopathogenesis and clinical challenges encountered in diagnosis and management, among diabetic patients.<br><br>RESULTS: Diabetes mellitus facilitates the acquisition and progression of fungal infections via multiple coordinated mechanisms viz. hyperglycemia, impaired immune (innate and adaptive) response, altered microenvironment and endothelial dysfunction. These changes in the milieu contribute to pervasive clinical presentations, ranging from cutaneous and oral candidiasis to invasive fungal diseases like mucormycosis, aspergillosis and cryptococcosis. Besides predisposing to fungal infections, diabetes also serves as a prognostic factor and has been noted to worsen the outcome. Furthermore, the altered microenvironment affects the pharmacokinetics of antifungal drugs and can also reduce the efficacy of antifungal regime, further convoluting and worsening the progression of disease.<br><br>CONCLUSION: Early diagnosis and management of fungal infections is necessary to mitigate the associated morbidity and mortality among diabetic patients. A multidisciplinary approach is imperative as diabetes hampers the effectiveness of conventional antifungal regimens and facilitates antifungal resistance. Regular monitoring of glycaemic index and compliance for drugs, along with lifestyle modifications desired for optimal levels, is pre-requisite for antifungal therapy to exhibit desired action.}, }

A growing body of evidences have indicated that different dietary components, like polyphenols, may also increase short-chain fatty acids production by gut microbiota, playing a preventative role against various diseases, such as type 2 diabetes (T2D), obesity, cardiovascular diseases (CVD), and even mitigate inflammation attributed to disorders like those observed in COVID-19 and even cancer. Some infectious illnesses alter the microbiome, resulting in a decrease in the production of fermentative products, such as short-chain fatty acids. Managing the microbiome with probiotics to compensate the changes caused by these diseases leads to improvements in the microbiome and a reduction in inflammation. This reduction may even have positive effects in managing cancer.

Communication strategies are pivotal for enhancing vaccine literacy, countering misinformation, and sustaining immunization programs.<br><br>OBJECTIVE: This systematic review evaluates the association between communication channels and vaccine hesitancy and adherence, while examining the moderating role of sociodemographic factors.<br><br>METHODS: A PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses)-compliant search was conducted across PubMed, Scopus, and Web of Science, yielding 17,407 records screened according to predefined eligibility criteria (peer-reviewed studies with N>1000 adults assessing communication media targeting vaccine hesitancy and adherence, excluding pediatric, health care-specific, and non-English research). After full-text assessment, studies were appraised using the Modified Medical Education Research Study Quality Instrument for methodological quality and the Joanna Briggs Institute Critical Appraisal Checklist, ROBIN-I (Risk of Bias in Nonrandomized Studies of Interventions), or RoB 2.0 (Risk-of-Bias 2.0 tool for randomized trials) tools for risk of bias.<br><br>RESULTS: Thirty-six studies were included (26 cross-sectional, 4 quasi-experimental, 4 randomized controlled trials, 1 cohort, and 1 global analysis). Randomized and nonrandomized experimental studies demonstrated that tailored communication strategies delivered via radio, web platforms, and social media significantly improved vaccine acceptance. Adaptive public health campaigns achieved up to an 8% weekly increase in uptake in Madagascar (relative risk 1.08; 95% CI 1.01-1.15) and a 7.8% higher vaccination rate among Nigerian adults at first follow-up compared with controls. Digital and social media campaigns effectively reduced hesitancy and enhanced trust among hesitant pregnant women in the United States. Sociodemographic factors significantly moderated communication outcomes: a COVID-19 chatbot proved most effective among individuals with lower education and minority backgrounds, while religiosity (b=0.17; 95% CI 0.05-0.30; t810=2.80; P=.005) and cultural congruence (odds ratio 1.89; P<.01) influenced message credibility and engagement, respectively. The persuasive effect of online memes on COVID-19 vaccine intentions was not significantly influenced by gender (P=.83), age (P=.60), or political orientation (P=.44). Age-specific effects were observed, with greater responsiveness to a social media campaign among adults aged 25-34 years and reduced hesitancy among older groups. Multiple cross-sectional studies indicated higher adherence among audiences exposed to traditional media (television, radio, newspapers) and lower trust among social media users. Other studies suggested significant influences of gender, age, socioeconomic status, education level, and political orientation.<br><br>CONCLUSIONS: By synthesizing fragmented evidence, this review provides a systematic examination of the interplay between multichannel media and vaccine acceptance. It diverges from existing literature by integrating both traditional and digital media perspectives through the lens of sociodemographic moderation. This work offers a critical framework for public health interventions, advocating for rigorous longitudinal research to establish definitive causal links between communication and behavior. Consequently, these findings support a "precision" communication model, enabling the development of culturally congruent strategies tailored to specific recipient profiles to bolster vaccine adherence.<br><br>TRIAL REGISTRATION: PROSPERO CRD42025637441; https://tinyurl.com/4r9w83kw.}, }

Stress triggers these disorders, precipitating initial episodes and provoking relapses. In this perspective, we argue that the stress system is not merely a threat mechanism but also an ongoing and active monitor of the environment and that resilience is not simply the lack of sensitivity to stress but an active function with an intrinsic neurobiology. Through the interplay of genetic, developmental, and experiential mechanisms, individuals evolve their own "stress-resilience algorithm" that determines their stress reactivity and the resulting adaptive or maladaptive consequences. This algorithm represents a dynamic, lifelong process that is often self-reinforcing. We underscore the importance of focusing on prevention by assessing and enhancing an individual's "stress fitness." This perspective offers a new conceptualization of the neurobiology of stress and resilience as a framework for basic and translational neuroscience research aimed at confronting the challenges of stress disorders.}, }

The data-sparse LMICs employ a multitude of estimation approaches to gauge maternal mortality ratios (MMR); however, their classification of deaths and reproducibility of estimates remain open to discussion. Despite a considerable reduction of MMR levels since 2000, more recently, the MMR levels in countries including the US have resurged due to the sociomedical crises brought about by the COVID-19 pandemic. The United Nations' Sustainable Development Goal (SDG) 3.1 aims to achieve global maternal mortality ratios of less than 70 per 100,000 live births and below 140 per 100,000 live births at the national level by 2030. However, recent projections indicate it will remain unmet by a margin of a million maternal deaths. Many LMICs apply the three-delays framework of maternal deaths that requires verbal autopsy to be used in tandem with the identification of maternal deaths. The three-delays model devised in the mid-1990s allows LMICs to gear their resources towards specific intervention points. A significant portion of the existing literature has focused on the description of the magnitude of the issue and the factors precipitating maternal deaths. Innovative solutions have recently been implemented, such as repurposing military helicopters to reduce the delays in managing obstetric complications. Similarly, prospective studies are required to devise ways to address the sociomedical mechanisms underlying maternal deaths.}, }

Although common, its influence on sexual satisfaction, sexual health, psychological well-being, and relational stability in LDRs remains understudied. Moreover, cultural and population differences shape diverse meanings and perspectives on masturbation.<br><br>OBJECTIVES: We employed a systematic review approach to explore the role of masturbation within long-distance relationships. Specifically, this review aims to examine how masturbation is associated with sexual, relational, and psychological outcomes and how these perspectives vary across cultural contexts.<br><br>METHODS: A systematic review was conducted following the PRISMA guidelines, compiling both quantitative and qualitative studies on masturbation as an alternative sexual activity in LDRs as well as its implications for sexual satisfaction, relationship satisfaction, and psychological well-being.<br><br>RESULTS: Fourteen studies were eligible for further analysis in which men reported higher frequencies of masturbation compared to women, with significant increases observed in the context of long-distance relationships and during COVID-19 quarantine periods. Men were mainly motivated by biological release, orgasm, and stress reduction, often with pornography, whereas women reported broader motives such as relaxation, better sleep, stress relief, and emotional closeness. The effects on sexual satisfaction were mixed: masturbation was reported to be associated with greater body awareness, self-esteem, and relational harmony, yet excessive frequency was linked to lower satisfaction and arousal. Mutual, technology-mediated practices helped maintain intimacy, while excessive solitary use undermined relationship quality. From a sexual health perspective, moderate masturbation may be associated with indirect benefits through improved body awareness, whereas frequent use was linked to poorer experiences. Psychologically, it served as a coping strategy for sleep and stress, but excessive engagement increased anxiety and reduced emotional well-being.<br><br>CONCLUSION: Masturbation appears to be a common and potentially adaptive alternative sexual activity in the context of LDRs and during the COVID-19 pandemic. However, in Eastern contexts, its meaning and impact are strongly shaped by sociocultural and religious norms.}, }

The heterodimeric adaptor Elongin BC (ELOB/ELOC) defies this stereotype: its BC-box-binding groove is a deep, rigid pocket that anchors dozens of cellular and viral partners to cullin-RING ligases and to transcriptional machinery. Recent structural and chemical-biology breakthroughs have converted this once "undruggable" site into a tractable target. A sub-nanomolar peptide derived from the chromatin factor EPOP has been shown to displace native BC-box proteins, trigger apoptosis in multiple cancer lines, and unveil a transcriptomic signature that converges on MYC and cell-cycle control. Parallel fragment screens and crystallography have mapped adjacent hot spots suitable for small-molecule growth, while functional genomics highlights Elongin BC as a pan-cancer dependency and an unexpected regulator of the SARS-CoV-2 co-receptor TMPRSS2. This review synthesizes the structural principles of BC-box recognition, the current state of peptide and fragment-based inhibitors, and the biological consequences of disrupting the Elongin BC hub. We discuss therapeutic prospects in oncology and virology, outline key challenges-delivery, selectivity, and resistance-and propose future directions ranging from stapled-peptide optimization to covalent fragment tethering and PROTAC strategies. Together, these advances position Elongin BC inhibition at the forefront of next-generation PPI drug discovery, offering a unified approach to modulate ubiquitin signaling, epigenetic regulation, and viral entry through a single conserved pocket.}, }

By comparing the genetic sequences of pathogens from different patients and sources, epidemiologists can determine the source of the outbreak and how the disease is spreading through populations. In addition, genome sequencing has the potential to identify mutations that may affect transmissibility, virulence, or resistance to treatment, providing critical insights for public health responses, for instance enabling targeted interventions, such as specific treatments or vaccines. During the last years, this was particularly evident for multiple internationally occurring severe outbreaks caused by either bacteria or virus, with special emphasis during the COVID-19 pandemic, where genome sequencing played a vital role in monitoring the emergence of new variants and informing vaccine strategies.

The overlap between metabolic impairment, viral pathophysiology, and chronic inflammation created a pattern that urged deeper examination. The aim of this paper was to review and synthesize evidence regarding the interaction between diabetes mellitus and COVID-19. We synthesized evidence across mechanistic pathways (immune dysregulation, chronic inflammation, ACE2/DPP-4-related signaling, endothelial dysfunction, and pancreatic involvement) and key clinical outcomes (severity, intensive care unit (ICU) admission, mortality, dysglycaemia/new-onset diabetes, and DKA). This systematic search was conducted in PubMed, Clinical Key, and Google Scholar. The eligibility criteria included papers on adults (≥18 years) with pre-existing diabetes mellitus (type 1 or type 2) or newly diagnosed diabetes/hyperglycemia and confirmed SARS-CoV-2 infection, published between January 2020 and October 2025, in English language. The PRISMA guidelines were used for data extraction. We identified 412 articles, out of which only 30 met all the inclusion criteria. Diabetes was consistently evoked as a major risk factor for severe COVID-19, being associated with higher susceptibility to pneumonia, respiratory failure, ICU admission, and mortality. The explanation lies in the impaired immune system, endothelial dysfunction, and metabolic repercussions imposed by hyperglycemia. Several antidiabetic drugs appeared protective in multiple cohorts. In conclusion, the accumulated evidence underscores the tight interplay between metabolic disease and COVID-19. Essentially, the clinical management of these patients would be a thoughtful selection of antidiabetic therapy and close metabolic monitoring.}, }

As a result, technologies utilizing ozone's microbicidal effects have been developed or improved for cleaning indoor areas, surfaces, and materials, despite ozone's diverse uses being known for years. Ozone offers the advantage of adaptability for both gaseous and aqueous use, depending on the nature of the decontaminated surfaces. Moreover, ozone-infused water is ecologically benign, possesses microbial-fighting capabilities, and synergistically reinforces the biocidal action of other chemical disinfectants. This review aims to summarize the efforts dedicated to harnessing gaseous and aqueous ozone as a valuable means to eliminate the SARS-CoV-2 virus from environments, surfaces, clinical equipment, and office supplies. This review sourced evidence-based articles from electronic databases, including MEDLINE (via PubMed), EMBASE, the Cochrane Library (CENTRAL), and preprint repositories. The findings illustrated that ozone could serve as an additional tool for curbing the proliferation of COVID-19 and other viral infections.

Methods: A focused narrative review (2020-2025) was conducted using clinical, experimental, and consensus evidence. The evidence was synthesized qualitatively, with priority given to cohort studies, meta-analyses, and mechanism-focused studies with clinical relevance. Results: Mucus obstruction ("mucus plugs") is frequent in COPD (41-67%) and is associated with unfavorable outcomes. COPD also increases the risk of post-COVID respiratory sequelae. Bacterial coinfection at presentation is uncommon (3-5%), whereas secondary bacterial infections are more frequent (14-18%), especially in severe disease requiring intensive care, where VA-LRTI/VAP (ventilator-associated lower respiratory tract infection/ventilator-associated pneumonia) become predominant. Sepsis, whether viral or mixed, reflects disease severity and may contribute to functional decline and susceptibility to reinfections; however, the concept of a post-acute "sepsis legacy" in COPD after COVID-19 should currently be regarded as a clinically plausible but still emerging hypothesis rather than an established COPD-specific outcome. During recovery, acute exacerbation risk rises to 5.6% versus 3.9%, peaking in the first 30 days after severe disease (aHR ≈ 8.14). Persistent dyspnea and reduced DLCO (diffusing capacity for carbon monoxide) suggest ARDS-related injury, tissue remodeling, and microvascular dysfunction. Conclusions: In COPD, post-COVID respiratory sequelae result from the interaction of mucus, immunity, and infectious/sepsis-related complications. The first post-discharge month is a critical period requiring careful risk stratification and targeted follow-up.}, }

Post-COVID-19 osteonecrosis of the jaw (PC-ONJ) has been described in association with both COVID-19-associated mucormycosis (CAM) and non-fungal phenotypes. This narrative review aims to synthesize and critically analyze the available evidence regarding terminology and classification, epidemiology and risk factors, pathophysiological mechanisms, clinical and imaging characteristics, diagnostic challenges, and management strategies relevant to oral and maxillofacial surgery practice. Materials and Methods: An extensive literature search was conducted in the PubMed/MEDLINE, Scopus, Web of Science, ScienceDirect, and Google Scholar databases. The search targeted peer-reviewed publications published between 2020 and 2025, reflecting the post-pandemic emergence of this clinical spectrum. Original studies, systematic and narrative reviews, multicenter case series, consensus guidelines, and well-documented case reports were considered. Results: Available data, largely derived from case reports and small series, demonstrate a predominance of maxillary involvement and frequent association with diabetes mellitus and systemic corticosteroid therapy. Proposed mechanisms include COVID-19-associated endothelial dysfunction, microvascular thrombosis, immune dysregulation, metabolic imbalance, and treatment-related effects. Clinically, patients may present with persistent orofacial pain, tooth mobility, exposed or probeable bone, and frequent sinonasal extension, with symptoms sometimes preceding bone exposure. Diagnostic challenges arise from the overlap with medication-related osteonecrosis of the jaw (MRONJ), osteoradionecrosis (ORN), and chronic osteomyelitis. Imaging is essential for assessing disease extent but remains insufficient for etiologic differentiation, making histopathological examination and targeted microbiological investigations necessary, particularly to exclude invasive fungal infection. Conclusions: Management must be etiology-driven. CAM requires urgent antifungal therapy combined with surgical debridement, whereas non-fungal forms are generally managed with conservative surgery and appropriate antimicrobial stewardship. Standardized diagnostic criteria and prospective multicenter studies are needed to reduce nosological ambiguity and optimize clinical decision-making in this emerging post-viral condition.}, }

The vagus nerve, through the cholinergic anti-inflammatory pathway, represents a theoretically attractive therapeutic target for modulating systemic inflammation. Vagus nerve stimulation (VNS) has emerged as a potential adjunctive treatment for COVID-19, with several randomized controlled trials (RCTs) investigating its efficacy on inflammatory biomarkers and clinical outcomes. The quality of this evidence base has not been rigorously evaluated. This systematic review critically appraises all available RCT evidence for VNS in hospitalized COVID-19 patients. Materials and Methods: We systematically searched PubMed, Scopus, Cochrane (CENTRAL), and Web of Science from database inception to January 2026, for RCTs evaluating any form of VNS (invasive, non-invasive, cervical, or auricular) in hospitalized patients with confirmed acute COVID-19. Two reviewers independently screened titles, abstracts, and full texts according to pre-specified eligibility criteria. Risk of bias was assessed using the Cochrane Risk of Bias 2 (RoB 2) tool, with assessments initially performed using multiple artificial intelligence tools and subsequently validated by the authors in accordance with PRISMA 2020 guidelines. Given substantial heterogeneity and high risk of bias, narrative synthesis was performed rather than meta-analysis. Also, GRADE assessment was performed. Results: From 437 records identified, six RCTs comprising 221 patients met the inclusion criteria. Five trials (83%) were rated as high risk of bias, primarily due to inadequate blinding, substantial baseline imbalances, significant missing data and extensive multiple testing without statistical correction. The single double-blind trial with a credible sham control (Rangon et al.) found null results across all outcomes, including clinical progression, ICU transfer, and mortality, while the five "high" risk-of-bias trials generally reported positive findings on various inflammatory markers and clinical outcomes. One trial (Corrêa et al.) measured heart rate variability as a direct indicator of vagal activation and found no change despite claiming anti-inflammatory effects, contradicting the proposed mechanism of action. Significant cognitive findings from an interim analysis (Uehara et al., n = 21) disappeared in the larger completed trial (Corrêa et al., n = 52), providing empirical demonstration of false positive findings in small, underpowered studies. Conclusions: Currently available evidence supporting the use of VNS for acute COVID-19 remains scarce; however, the physiological rationale remains sound, although the absence of reliable target engagement markers in the included studies limits confidence in this treatment method. Large-scale, double-blind, sham-controlled trials are required before VNS can be firmly recommended for COVID-19 management.}, }

The CMGC family comprises a large group of serine/threonine kinases defined by a conserved catalytic core and closely related kinase domains. While several CMGC members have been extensively studied, others, including the RCK and CDKL subfamilies, remain less studied. Here, we synthesize current knowledge of CMGC kinases, emphasizing their structural organization, mechanisms of activation, and roles in infection and disease. CMGC kinases such as CDKs and DYRKs are activated downstream of growth factor signaling to drive proliferative programs. In contrast, other CMGC members respond to cellular stress signals, including stress cytokines, and function during quiescence or adverse conditions to regulate antiproliferative and pro-survival pathways. Through these context-dependent activities, CMGCs govern fundamental cellular processes, including growth, metabolism, transcription, and genome integrity. Although individual CMGC kinases operate within distinct signaling cascades, substantial crosstalk exists among their pathways. Both DNA and RNA viruses exploit host CMGC networks to reprogram the intracellular environment and enhance replication. While CMGC-virus interactions are often proviral, specific CMGC-mediated antiviral responses have been described, notably in SARS-CoV-2 infection. Collectively, CMGC kinases occupy a central position in cellular homeostasis and disease.}, }

These signaling cascades control cytokine production, T cell activity, and antigen presentation. However, many viruses can hijack MAPK pathways to avoid immune detection, promote their replication, and establish chronic infection. In this review, we discuss how different viruses, including HSV-1, HBV, HCMV, and SARS-CoV-2, manipulate MAPK signaling to alter host cell functions. A particular focus is given to the CD1d-iNKT cell axis, which plays a critical role in early antiviral responses but is often disrupted through MAPK-dependent mechanisms. We explore how changes in MAPK signaling affect antigen-presenting cells, drive T cell exhaustion, and reprogram immune cell metabolism, factors that contribute to viral immune evasion. The review also examines therapeutic strategies aimed at targeting MAPKs to improve antiviral immunity. These include small-molecule inhibitors and immune modulators that may enhance antiviral responses while limiting side effects. We emphasize the importance of context, as MAPK-targeted therapies must be carefully timed and tailored to avoid suppressing protective immunity or triggering unwanted inflammation. Overall, this review highlights the therapeutic potential and challenges of targeting MAPK pathways in viral infections and encourages further research into selective, host-directed antiviral strategies.}, }

Approaches include targeting viral transcripts directly (e.g., siRNAs against HBV surface antigen) or host factors critical for viral replication (e.g., anti-miR-122 miravirsen for HCV). The successful development of mRNA vaccines for COVID-19 is highlighted as a major breakthrough, demonstrating the feasibility of rapid RNA vaccine deployment. The manuscript reviews several RNA therapeutics in oncology that have reached clinical trials. These include TargomiR (a miR-16 mimic for mesothelioma), cobomarsen (an anti-miR-155 for lymphomas), and MRX34 (a miR-34a mimic for various solid tumours). The review also covers emerging candidates like an miR-221 inhibitor and various strategies for breast cancer, such as targeting Bcl-2, KRAS, and specific miRNAs. A critical challenge across both fields is developing efficient and safe delivery systems, including lipid nanoparticles, GalNAc conjugates, and bacterial minicells. Despite promising preclinical results, clinical translation has been hampered by issues like insufficient delivery efficiency to human tumours, toxicity, and the complex, interconnected regulatory networks of miRNAs, which can lead to unpredictable off-target effects. Conclusions: While RNA therapeutics hold immense promise, overcoming delivery barriers and enhancing understanding of RNA regulatory networks are essential for future success.}, }

Meanwhile, many computational models utilising the Monte Carlo (MC) technique have been developed as a cost-effective and scalable method for investigating these effects. Hence, this review explores the application of the MC technique in modelling skin pigmentation, focusing specifically on how melanin in the epidermis is represented across different studies. First, the biological mechanisms of pigmentation and current stratification methods are outlined to contextualise the variability in skin tone, followed by the principles of MC modelling, including photon scattering, absorption, reflection, and detection. Following a screening and exclusion process, 50 studies were evaluated in terms of how melanin concentration and distribution are incorporated into MC models and their applications, revealing a range of approaches that include analytical equations, experimental optical property measurements, or hybrid methods. The benefits and limitations of each approach is discussed, in addition to emerging advancements such as heterogeneous melanin distribution and the relation between optical properties and skin colour classification scales. Overall, the review outlines the current methodological approaches utilised for skin pigmentation modelling and offers a reference framework for researchers seeking to improve the representation of skin pigmentation in MC-based optical simulations.}, }

Thematic analysis organised the findings into three main themes: i) the prevalence of sleep quality and physical activity in Asia; ii) the association between sleep quality and physical activity; and iii) sleep quality and physical activity during the COVID-19 outbreak. These findings reveal a high prevalence of sleep deprivation and poor sleep quality among young adults in Asia, whereas the prevalence of physical activity varies. Moreover, the COVID-19 outbreak negatively affected sleep quality and physical activity. Therefore, proactive measures should be implemented to improve sleep quality and promote physical activity, thereby improving physical and mental health.}, }

PubMed, Embase, and Scopus were searched from 2020 to December 31, 2025. Primary outcomes were overall survival (OS) and progression-free survival (PFS); secondary outcomes included objective response rate (ORR) and disease control rate (DCR). Hazard ratios (HRs) and odds ratios (ORs) with 95% confidence intervals (CIs) were pooled using random-effects models.<br><br>RESULTS: Ten observational studies comprising 4,929 patients receiving ICIs were included. COVID-19 vaccination was associated with significantly improved PFS (pooled HR&#xa0;=&#xa0;0.66, 95% CI 0.48-0.90) and OS (pooled HR&#xa0;=&#xa0;0.51, 95% CI 0.39-0.66) compared with no vaccination.

Respiratory epithelial cells (RECs) as the primary targets of SARS-CoV-2 via the ACE2 receptor, act as central mediators of immune crosstalk that balances antiviral defense and immunopathology in COVID-19. Beyond forming a physical barrier against pathogen invasion, RECs regulate bidirectional crosstalk with immune cells (including alveolar macrophages, dendritic cells, neutrophils, and lymphocytes) through multiple mechanisms, such as cytokine signaling, antigen presentation, PD-L1 checkpoint modulation, and renin-angiotensin-aldosterone system (RAAS) dysregulation. Under physiological conditions, these interactions promote viral clearance and epithelial repair; In contrast, dysregulation of such crosstalk leads to excessive inflammatory responses like cytokine storm and impaires tissue regeneration. Elucidating the molecular dynamics underlying REC-immune crosstalk is crucial for gaining insights into the development of targeted therapies (e.g., modulating cytokine signaling, restoring RAAS balance) to mitigate the severity of COVID-19. This review summarized recent findings to clarify how REC-mediated immune crosstalk dictates antiviral responses and pathological outcomes, thereby providing a theoretical basis for optimizing therapeutic strategies that strengthen antiviral immunity while minimizing immunopathology.}, }

Though our search strategy aimed to capture studies from any outbreak since 2014, all quantitative evidence on VAWG impacts, and all but one qualitative study, focused on the COVID-19 pandemic, and only three studies disaggregated outcomes for women versus girls. Overall, our synthesis of the evidence points to increased VAWG during the first year of the COVID-19 pandemic compared with pre-pandemic levels. We identified five broad mechanisms through which violence occurred against women and girls: (1) income loss due to economic shutdown, financial insecurity, and/or job loss, (2) movement restrictions, (3) changes in access to public services, (4) fear of exposure to infectious disease, and (5) a legacy of mistrust in health systems from previous outbreaks. Our study demonstrates the novelty of VAWG monitoring during outbreaks, the need for increased surveillance and the known mechanisms to date through which VAWG may be perpetrated during outbreaks. By implementing both short-term protective measures and long-term structural reforms, outbreak responses may not only break the cycle of VAWG exacerbated by public health emergencies but build resilient systems that protect women, girls and marginalised populations before, during and after crises.}, }

Keywords were selected from the MeSH database. We excluded review articles, books, letters, reports, and other non-original sources, as well as studies that focused on mobile phones or populations other than university students and smartphone users. Additionally, articles addressing pain in other body parts, injuries, and complications from smartphone use, as well as those published during the COVID-19 pandemic, were also omitted. We utilized various keyword combinations related to "university", "students", "smartphone use", "addiction", "overuse", "hand", "pain", "musculoskeletal pain", "wrist", "fingers", "thumb", "risk factors", "characteristics", and "posture" in the search, along with the use of "AND", "OR", or no conjunctions, and the use of quotation marks for one, two, or a few keywords.

A total of 18 studies were selected from 390 primary literature sources, following the PRISMA framework.<br><br>RESULTS: A total of 393 articles were found in the initial search. Duplicate articles were removed, leaving 259 that were examined according to inclusion and exclusion criteria. After assessing the relevance of titles and abstracts, screening, and qualitatively evaluating journals, 18 articles were included in the study. Brazil, Saudi Arabia, and Turkey had the highest number of articles (n&#x2009;=&#x2009;3 or 16.6% of articles). The age group investigated was 18 to 26 years old. Based on the identified risk factors, the articles were discussed in three groups: (1) role of smartphone duration, addiction, and hand pain (83.3% of studies investigated the duration of smartphone use, while 38.8% surveyed smartphone addiction), (2) the effect of smartphone holding posture on the hand and hand pain (38.8% of studies), and (3) the relation of smartphone physical characteristics to hand pain (27.7% of studies). Daily usage duration ranged from less than or equal to 4&#xa0;h/day (53.2%) to 7&#xa0;h or more (73.9%). The reported range of smartphone addiction among students was between 15.9% and 66.6%. The reported prevalence of wrist, hand, and thumb pain was 19.2% to 68.7%. Between 14.75% and 41% of students use their right hand to hold smartphones and type with their right thumb, while 24% to 77.79% use both hands and both thumbs. The size and weight of smartphones can predict hand pain.<br><br>CONCLUSIONS: The amount of time spent using a smartphone, how it is held, how long it has been owned, smartphone addiction, holding posture, frequent thumb movements, preferred hand position, screen size, weight of the smartphone, and smartphone -related the purpose of usage are all risk factors that can lead to pain in the hand, wrist, palm, thumb, and other fingers.}, }

Since the early 1970s, PEDV has shown strong genetic flexibility, the ability to evade immunity, survive in the environment, and spread quickly through connected livestock networks. Major outbreaks in Asia, Europe, and North America, especially the 2013-2014 outbreak in the United States, have revealed key weaknesses in traditional control methods for enteric coronaviruses, especially those that depend on systemic immunization. In this review, we bring together over fifty years of PEDV research to look at how viral evolution, mucosal immune responses, and livestock production systems work together to keep the virus circulating. We point out that changes in the spike gene, including recombination and deletions, along with changes in other viral genes, affect disease severity, immune system recognition of the virus, and the inability of vaccines to provide protection. We also stress the key role of lactogenic immunity and the gut-mammary-secretory IgA system in protecting newborn animals, which helps explain why vaccine inoculations have not been effective in stopping the spread of enteric coronaviruses. By combining evidence from molecular, immune, epidemiological, and systems research, we suggest that PEDV is a strong example for studying how coronaviruses persist under immune pressure in managed animal groups. Using a One Health approach, this review encourages moving away from only reacting to outbreaks and instead focusing on ongoing, genome-based management of coronaviruses in livestock operations.}, }

Despite the increasing VV ECMO use, contemporary guidance on hemodynamic monitoring remains limited and largely experience-based. This scoping review aimed to map available basic and advanced monitoring approaches and to identify current evidence gaps.MethodsPubMed, EMBASE, and Cochrane CENTRAL were searched from inception until September 2025, along with reference lists of relevant articles. We included studies of any design reporting techniques, targets, or protocols for hemodynamic monitoring during VV ECMO.ResultsOf 465 records screened, 106 met inclusion criteria. No protocolized, evidence-based hemodynamic monitoring protocol specific to VV ECMO was identified. The available evidence was heterogeneous and mostly derived from physiologic studies or single-center observational cohorts. Findings were narratively synthesized across three domains: basic bedside monitoring, diagnostic/prognostic tools and advanced assessment of cardiopulmonary interaction. Across studies, no monitoring strategy consistently reduced time-to-wean or mortality. Observational data suggested that care bundles and multidisciplinary approaches may reduce complications. However, the risk of bias limits causal inference.ConclusionsDespite the complex interaction between native cardiovascular function and extracorporeal circulation, VV ECMO lacks consensus on evidence-based hemodynamic monitoring pathways. A pragmatic core monitoring bundle with tiered triggers for escalation is necessary. Future priorities include implementation models based on multidisciplinary teams, specific training, standardized bundles, and multicenter studies aimed to define right ventricular-centered targets to improve safety and clinical decision-making.}, }

A structured data extraction process was applied to collect information on sample characteristics, health-related outcomes, and associated variables (protective and risk factors). Descriptive statistics were used to synthesize frequencies, proportions, and distributions of measurement instruments and constructs across the included studies.<br><br>RESULTS: A total of 223 studies were included. Samples were largely non-probabilistic and female-biased. Ill-being measures appeared exclusively in 66.3% of the studies, while 7.9% focused on well-being, and 25.8% included both. A total of 159 instruments assessing well-being and ill-being were identified. Of these, the majority measured ill-being (118 instruments), followed by instruments assessing well-being (28), and a smaller number addressing both constructs (13). In addition, 154 instruments measuring lifestyle were identified. Lifestyle behaviors were measured in a fragmented, health-risk-oriented manner, often lacking contextual influences. Individual predictors (130) were prioritized over relational and environmental factors (53).

A perplexing clinical phenomenon has been observed: some children with a history of Long COVID exhibit a disproportionately severe inflammatory response and extensive lung injury when encountering common community-acquired pneumonia, such as that caused by Mycoplasma pneumoniae or Streptococcus pneumoniae, inconsistent with their pathogen load. This review aims to dissect this phenomenon and proposes the "Immune Priming and Two-Hit" model as its core pathophysiological framework. This model posits that the Long COVID state constitutes the "first hit," establishing a "primed" or "hyper-reactive" immune baseline through viral persistence, trained immunity-induced monocyte reprogramming, and sustained endothelial dysfunction. Upon the "second hit" of a bacterial infection, this primed immune system triggers a dysregulated, synergistically amplified inflammatory cascade. The mechanisms involve the exponential release of cytokines such as Interleukin-6 (IL-6), IL-1β, and Tumor Necrosis Factor-α (TNF-α), inflammation-mediated immunothrombosis, and excessive activation of Neutrophil Extracellular Trap formation (NETosis), ultimately leading to severe outcomes like Acute Respiratory Distress Syndrome (ARDS) and necrotizing pneumonia. Consequently, identifying and defining this "Hyper-inflammatory endotype" is of critical clinical importance. We define it as an "endotype" to emphasize the distinct, host-determined pathophysiological mechanisms underlying it, rather than merely a collection of clinical manifestations. By monitoring biomarkers such as ferritin, D-dimer, lactate dehydrogenase (LDH), and lymphocyte counts, clinicians may be able to perform early risk stratification of these children. This approach not only facilitates a shift in therapeutic strategy from purely antimicrobial therapy to "host-directed therapy"-emphasizing the necessity of early, adequate corticosteroid use and consideration of anticoagulation-but also provides a new theoretical basis and intervention window for preventing long-term sequelae such as pulmonary fibrosis.}, }

In the current absence of effective monoclonal antibodies to SARS-CoV-2, standard commercial intravenous/subcutaneous immunoglobulin (IVIG/SCIG) lots provide an option for passive immunotherapy since these now consistently contain SARS-CoV-2-reactive antibodies. Strong mechanistic considerations and emerging observational data support the use of IVIG/SCIG as a biologically plausible option for COVID-19 pre-exposure prophylaxis (PreEP) in immunocompromised patients. In this review, we summarize the supporting evidence available and consider optimal use cases. Neutralization capacity against Omicron lineages is consistently reduced and highly variable between lots, and there is an intrinsic several-month lag between donor immunity and product infusion. The available information in literature sources consistently reflects the use of standard replacement dosing of IVIG/SCIG and does not systematically analyze COVID-19-specific safety or outcomes with dose intensification. While the available evidence suggests that IVIG/SCIG may be effective in PreEP, without dedicated randomized or well-controlled human trials, the magnitude of clinical benefit from this intervention remains uncertain, especially against contemporary Omicron sublineages.}, }

The COVID-19 pandemic, together with the increased spread of parasitic diseases driven by climate change and human migration, has renewed interest in metal-based compounds as antiviral and antiparasitic agents. These efforts have been further enabled by advances in computational modeling and mechanistic analysis, allowing rational design strategies that extend beyond in vitro drug screening. This focused review traces a coherent body of work, including studies developed by our research group, illustrating how fundamental coordination chemistry principles can be progressively integrated to address infectious disease challenges. Viral molecular targets, exemplified by the HIV-1 nucleocapsid protein NCp7, a zinc finger protein essential for multiple stages of retroviral replication, demonstrate how combined spectroscopic, mass-spectrometric, and computational approaches enable molecular-level understanding of metal-mediated zinc finger inhibition. Similar principles have been extended to neglected and emerging viral pathogens, including arboviruses such as Zika and chikungunya, where metal-based compounds can be modulated to interfere with different steps of replication cycle. In contrast, kinetoplastids such as Leishmania spp. present a complex intracellular environment in which the biological activity of metal complexes is governed predominantly by redox perturbation, disruption of thiol-dependent metabolism, and mitochondrial dysfunction. By following a continuous methodological and conceptual progression from drug-screening to mechanistic approach and in vivo models, this review highlights this transition and underscores the potential of metallodrugs in infectious disease agents.}, }

Eligible studies involved 229,142 autoimmune patients treated with HCQ, of which 197,118 patients were diagnosed with COVID-19. In 14 observational studies (196,965 patients), HCQ use was associated with a lower overall mortality rate by 21%&#xa0;in patients with autoimmune diseases and COVID-19 (RR 0.79; 95% CI: 0.64-0.97, p = 0.02). This association may reflect a potential survival benefit; however, given the observational nature of the studies included,&#xa0;causal inference cannot be established, and the findings should be interpreted cautiously. There was no significant difference between HCQ-treated patients and untreated patients regarding hospitalization (12 studies with 2,238 patients included), ICU admission (8 studies with 527 patients included), mechanical ventilation (8 studies with 546 patients included), sepsis (2 studies with 132 patients included), or thrombo-embolic events rates (2 studies with 195 patients included) (RR 0.92, 95% CI 0.75- 1.14; p = 0.46), (RR 1.45; 95% CI; 0.82- 2.56, p = 0.2) and (RR 1.28; 95% CI; 0.68- 2.4, p = 0.44), (RR 1.44; 95% CI; 0.57 - 3.65, p = 0.44), (RR 0.89; 95% CI; 0.16-4.97, p = 0.89), respectively. Nonetheless, the incidence of Acute Kidney Injury (AKI) in 2 studies (136 patients) was higher in HCQ-treated groups compared to the untreated groups (RR 2.31; 95% CI; 1.29-4.12, p = 0.0047).<br><br>CONCLUSION: HCQ was associated with a significantly lower overall mortality rate in patients with autoimmune diseases and COVID-19; this association is consistent with its known immunomodulatory properties. On the other hand, it does not prevent COVID-19-related complications and could be associated with an increased risk for developing AKI.

However, their inherent immunogenicity presents a double-edged sword: beneficial adjuvant effects in vaccination can become detrimental inflammatory responses in applications like treating inflammatory/fibrotic diseases or gene editing-based therapies. This review comprehensively evaluates LNP-associated inflammation and mitigation strategies. We begin with an in-depth analysis of molecular mechanisms, detailing how specific lipid components, endocytic pathway activation, and nucleic acid sensing drive immune stimulation. Key modulatory factors, including LNP structural characteristics, administration routes, and biodistribution, are examined. We then explore cutting-edge engineering approaches to circumvent immunogenicity, encompassing structure-guided design of ionizable lipids, sophisticated biomimetic strategies using natural membrane coatings, innovative co-delivery systems incorporating anti-inflammatory agents, and emerging technologies for immune-evasive LNPs. By elucidating the intricate relationship between nanocarrier physicochemical properties and host immune recognition, while addressing translational hurdles, this review provides critical insights for developing safer, next-generation LNPs tailored for diverse therapeutic applications.}, }

Despite long-standing monitoring systems and regulations, comprehensive assessments that combine multiple data sources with health impact analysis are still lacking. This study reviews peer-reviewed studies, haze events from 1983 to 2024, regulatory documents from the Department of Environment, Malaysia, and data from air quality monitoring stations across regions. and presents an integrated assessment of air quality across strategic and important urban, industrial, coastal, and residential areas. It analyses trends in the Air Pollutant Index and PM2.5 levels from 2013 to 2024, and uses exposure-response models to estimate related deaths and economic impacts. Satellite data (MODIS and AERONET) help understand spatial variation and cross-border pollution. Average PM2.5 levels ranged from 8.66-16.77 µg/m[3], consistently above WHO guidelines from 2021. In 2020, PM2.5 exposure was linked to 1.419 early deaths in four urban areas, costing about MYR 2.46 billion (USD 524 million). Population-attributable fractions ranged from 2.6-7.1%, with risk rising by 2.7-7.6% per 10 µg/m[3] increase. The study identified 12 major haze events, notably in 1997 and 2015. COVID-19 restrictions temporarily reduced emissions, but levels quickly rebounded afterward. Conclusively, Malaysia's air quality issues are mainly due to transport, industry, dust, and recurring transboundary haze. Solutions include better source tracking, enhanced secondary pollutant monitoring, integrating health data more effectively, adopting advanced technologies, and aligning policies with WHO standards. Pollution effects are more pronounced in metropolitan regions due to proximity to dense sources.}, }

Inclusion criteria were adults aged 60&#xa0;years, with loneliness as the primary or secondary outcome. Study quality was assessed using GRADE and Cochrane risk of bias tools. Subgroup analyses explored intervention type, measurement scales, national development level, pandemic timing and some secondary outcomes.<br><br>RESULTS: Seventeen studies (n&#x2009;=&#x2009;2423) showed DHIs significantly reduced loneliness scores (standardized mean difference [SMD]&#x2009;=&#x2009;-0.39, 95% CI -0.77 to -0.01).

Envelope glycoprotein function has traditionally been viewed through the lens of kinetic control, where environmental cues like pH trigger irreversible refolding from the pre-fusion conformation to the post-fusion conformation. Single-molecule Förster resonance energy transfer (smFRET) imaging has revealed an additional layer of thermodynamic control that governs the conformational dynamics of envelope glycoproteins in their pre-fusion form. smFRET studies of the envelope glycoproteins from HIV-1, SARS-CoV-2, MERS-CoV, Ebola virus, and influenza A virus demonstrate that these glycoproteins dynamically sample an ensemble of pre-fusion conformations whose relative stabilities respond to pH, receptor binding, ions, and host proteases. This thermodynamic tuning precedes the kinetically controlled transition that promotes membrane fusion. Collectively, smFRET imaging has transformed our understanding of viral entry, illustrating how the pre-fusion energy landscape of envelope glycoproteins is tuned by the host environment to maintain viral fitness.}, }

There is now a substantial body of evidence demonstrating that PiNO is an effective treatment option for managing hypoxaemia during general anaesthesia in horses. The administration of PiNO to well-ventilated alveoli leads to a redistribution of pulmonary blood flow from dependent, nonventilated regions to nondependent, better ventilated regions of the lung. This reduces intrapulmonary shunting and improves indices of oxygenation and oxygen delivery. Whilst much of the evidence is experimental, there are some descriptions of its successful use in client-owned horses undergoing surgery for colic and arthroscopic procedures. As the prototypical delivery device (the NOrse, Datex-Ohmeda Research Department, Helsinki, Finland) has been redeveloped, the use of PiNO in clinical equine anaesthesia may offer a realistic treatment option for the management of hypoxaemia in anaesthetised horses in the near future.}, }

This qualitative study used Self-Determination Theory and the Psychology of Working Theory to explore how motorbike delivery work promotes or undermines riders' psychological needs of competence, relatedness and autonomy. Ten motorbike delivery riders in Johannesburg, Gauteng, participated in twenty semi-structured interviews (two per participant). Hybrid thematic analyses were employed to analyse the data. Findings indicated that, amidst high unemployment and limited job opportunities in South Africa, platform-based motorbike delivery work partially satisfies riders' psychological needs. Relatedness was supported in interactions with customers and co-workers but limited by experiences of social stigmatisation. As independent contractors, riders enjoyed greater labour market flexibility and often earned more than in previous jobs, both of which promoted their autonomy. However, constant concerns regarding personal safety severely undermined this need. Challenges such as limited training and procedural injustice also restricted their need for competence. This study extends the Psychology of Working Theory by demonstrating how structural constraints not only influence the attainment of decent work but also shape the outcomes of decent work, specifically the fulfilment of psychological needs in precarious labour contexts.}, }

The emergence of three zoonotic coronaviruses-severe acute respiratory syndrome coronavirus (SARS-CoV) in 2002, Middle East respiratory syndrome coronavirus (MERS-CoV) in 2012, and SARS-CoV-2 in 2019, has had profound health, economic, and societal consequences and continues to influence global epidemic-preparedness strategies. All three viruses remain on the WHO Blueprint of priority pathogens for research and development. This Review summarises current knowledge on human coronaviruses, drawing lessons from the past 25 years of epidemic outbreaks. The shared and divergent features of SARS-CoV, MERS-CoV, and SARS-CoV-2, including their origins, evolution, transmission determinants, zoonotic transmission, viral entry pathways, pathogenesis, spectrum of clinical manifestations, long-term sequelae, and case-fatality profiles are highlighted. The full range of clinical manifestations, from asymptomatic or atypical presentations to severe acute respiratory and multisystem disease, are outlined together with risk factors for progression and populations with the greatest susceptibility. Diagnostic approaches, including molecular assays, antigen-based tests, and imaging modalities are described alongside current therapeutics, antiviral strategies, immunomodulators, supportive care principles, and evidence from clinical trials. Advances in diagnostics, vaccines, therapeutics, and infection-control practices are examined together with persistent challenges in early recognition, particularly in resource-limited settings. Strengthening multinational clinical trial capacity, leveraging digital innovations, and embedding One Health approaches are essential to mitigating spillover risks and improving global readiness. We review the latest data, identify gaps and opportunities, and outline forward-looking strategies to anticipate and prepare for the threat of future coronaviruses, and other existing or new respiratory pathogens with epidemic potential. Clinicians and other health-care workers play a central role in detecting and reporting possible lethal coronavirus infection including atypical presentations, enabling rapid, coordinated infection control and management responses.}, }

Reported social determinants aligned with structural factors (socioeconomic and political contexts, cultural norms, gender disparities) and intermediary factors such as academic stress, service access, and behavioral patterns including substance use, physical activity, sleep, and diet.<br><br>CONCLUSION: Although many studies addressed social determinants of student mental health in SSA, none provided comparable, multi-country data across HEIs. Most research focused on undergraduate particularly medical students, with limited attention to postgraduate populations. Future work should prioritize multi-country comparative studies and context-specific approaches that strengthen help-seeking and support for at-risk students across diverse SSA settings.}, }

As such, countries adopted a diversity of approaches, providing an opportunity to evaluate the configuration and evolution of border screening systems. The article addresses three questions: (i) how did countries configure their border screening systems for COVID-19? (ii) In what contexts did countries rely on public or private providers of these services? (iii) what do policies and narratives reveal about the perceived role of border screening in global public health? The article contributes to long-standing debates over the private sector's role in public health and the perceived value of border screening measures.<br><br>METHODS: This article presents results from an international comparative study based on tracking the organisation of border screening in eight countries. Secondary data was collected between July 2021 - June 2022 from official government websites and policy publications, private sector sources where relevant, and trusted media sources in each study country. The countries included are Australia, Canada, Germany, Ireland, South Africa, South Korea, Spain, and the United Kingdom.<br><br>RESULTS: All study countries used private provision for pre-departure diagnostic testing for international travellers. In contrast, screening of arriving travellers was more diverse. Countries that opted for private sector post-arrival screening saw governance challenges around accreditation and monitoring of providers, while public service provision saw challenges in capacity and high resource costs. Travel was often framed as a 'luxury,' allowing states to shift responsibility for obtaining tests onto individuals; especially in the context of individuals travelling from low income to high income countries.<br><br>CONCLUSIONS: The different approaches countries followed for screening of departing and incoming travellers suggests wealthy countries were more oriented towards defending their populations against disease importation, rather protecting the international community from disease exportation. These findings provide an opportunity to reflect on the purpose and implementation of border screening. We emphasise a need for further discussion on the efficacy of border screening from both perspectives, given the tendency for countries to rely on these measures.}, }

During the COVID-19 pandemic, breastfeeding support, which was traditionally provided offline, shifted to online platforms. Although these remote services were available before the pandemic began, online interventions emerged as an alternative and proved effective in helping mothers breastfeed during that period. We aimed to explore the existing literature on the experiences of mothers and health care professionals with remote one-to-one synchronous breastfeeding support and to identify the unmet support needs of mothers regarding this type of support. We systematically searched seven literature databases: MEDLINE, CINAHL Plus, MIDIRS, Web of Science, ASSIA, WHO Global Index, and Google Search. Articles published before 2010 and in languages other than English and Bahasa were excluded. A thematic approach was used to synthesise the data. Twenty-one studies were included in this review. Three themes generated from the synthesis: (1) mothers' acceptance of one-to-one synchronous telelactation, (2) benefit of one-to-one synchronous telelactation, and (3) challenges faced in one-to-one synchronous telelactation. In conclusion, mothers generally accepted one-to-one synchronous breastfeeding support as an alternative to in-person sessions, although some challenges remain. Further improvements are needed to address accessibility and scheduling issues.}, }

Although most regress uneventfully, a significant minority risk ulceration, functional compromise, or disfigurement, and therefore require timely intervention. The therapeutic landscape was once dominated by corticosteroids, interferon, and cytotoxic chemotherapeutics of modest efficacy and considerable toxicity. Management was revolutionized in 2008 by the discovery that the beta-blocker propranolol induced prompt and sustained regression. Propranolol has since become the established first-line therapy for IH, with efficacy and safety confirmed by randomized controlled trials and corroborated by observational cohorts. Mechanistically there are multiple temporally stratified actions: immediate vasoconstriction, suppression of angiogenic signalling pathways, induction of endothelial apoptosis, and ultimately the promotion of adipogenic differentiation in keeping with natural involution. Safety is favourable under expert supervision, though hypoglycemia remains the principal preventable hazard, necessitating caregiver education on feeding regimens and "sick day" rules. Rebound growth, encountered in roughly one-fifth of cases, usually responds to re-treatment. Alternative beta-blockers such as atenolol and nadolol provide comparable efficacy with potential advantages in tolerability or dosing convenience. Topical timolol has limited effectiveness for small superficial lesions, while sirolimus, becaplermin gel, laser devices, and surgery may have circumscribed adjunctive roles. Corticosteroids and cytotoxic agents are now confined to salvage use. Contemporary perspectives extend beyond pharmacology to encompass caregiver experience and health-system burden. Recent work highlights the low burden of treatment with propranolol, while digital innovations such as photo-triage during the COVID-19 pandemic illustrate opportunities to reduce healthcare exposure and improve equity of access. This review describes the evolution of drug therapy for IH and integrates mechanistic insights, clinical pragmatism, and patient-centred innovations to chart the current trajectory of care.}, }

Increasing evidence demonstrates that SpO2 may systematically overestimate arterial oxygen saturation (SaO2), particularly in individuals with darker skin pigmentation, thereby increasing the risk of occult hypoxemia-arterial hypoxemia not detected by pulse oximetry. We sought to synthesize current evidence and define implications for pediatric and congenital heart disease populations. We performed a narrative review of experimental physiology studies; observational adult and pediatric cohorts; pediatric COVID-19, ICU, and cardiac ICU investigations; device-comparison analyses; systematic reviews; and regulatory evaluations reporting paired SpO2-SaO2 measurements or validated reference standards stratified by race, ethnicity, or objectively measured skin pigmentation. Data sources included PubMed, MEDLINE, and bibliographies of relevant studies. Experimental data demonstrate directional SpO2 overestimation that increases during hypoxemia. Large adult cohorts confirm higher rates of occult hypoxemia in patients with darker skin pigmentation, findings subsequently replicated in hospitalized children. Emerging pediatric cardiac ICU data suggest that physiologic complexity may further amplify SpO2-SaO2 discordance. Device-comparison studies reveal variability across manufacturers, influenced by calibration datasets and signal-processing algorithms. Across populations, misclassification is most clinically relevant near commonly used escalation thresholds. SpO2 frequently overestimates SaO2 in darker skin pigmentation and during hypoxemia, increasing vulnerability to occult hypoxemia in hospitalized and critically ill children. In pediatric cardiac populations-where narrow saturation thresholds guide management-contextual, bias-aware interpretation of pulse oximetry is essential to support accurate decision-making and equitable care.}, }

Widespread nonpharmaceutical interventions (NPIs) sharply suppressed common pathogens, including human metapneumovirus (HMPV).

Unlike influenza or RSV, HMPV's post-pandemic behavior has challenged long-held assumptions about seasonal respiratory virus dynamics. Traditional late-winter peaks have given way to out-of-season surges, year-round co-circulation with other viruses has become commonplace, and existing surveillance systems designed for a pre-pandemic world have proven inadequate. This review examines HMPV's renewed clinical and public health significance, focusing on epidemiological shifts, health system pressures, diagnostic gaps, and the critical need for coordinated, multi-pathogen preparedness.

Early activities centered around storage and distribution of antitoxins and vaccines. From the 1950s through the early 1990s, pharmacists were facilitating administration of vaccines by other health care providers. In the early 1990s, efforts began to allow pharmacists to administer vaccines, with the first pharmacist immunization training in 1994. By 2009, all 50 states allowed pharmacists to administer vaccines. From the 1990s onward, pharmacists increasingly contributed to national vaccine policies and guidelines, and states expanded their authority to a broader range of patient ages and vaccines. The coronavirus disease 2019 (COVID-19) pandemic opened more opportunities for pharmacy-based involvement, including federal expansion of immunizing authority to children aged 3 years and older, and the authority for pharmacy technicians and student pharmacists to administer vaccines. Pharmacists and their teams administered more than 50% of the COVID-19 vaccines. Today, the majority of adult vaccines are administered in pharmacy-based settings.

Over the past 3 decades, cytosolic and nuclear Fe-S proteins have emerged as integral components of DNA replication and repair machineries, telomere maintenance pathways, transcriptional processes, cell cycle regulation, and protein synthesis. More recently, ISCs were identified in viral proteins, including multiple components of the SARS-CoV-2 replication and transcription complex (RTC), which collectively host seven experimentally verified Fe-S cofactors. The coexistence of multiple ISC-dependent enzymes within both cellular and viral replication machineries raises fundamental questions about how these metal cofactors coordinate genome maintenance, replication, and host-virus interactions. Here, we provide an inventory of known mammalian nucleocytoplasmic Fe-S proteins, discuss mechanisms of ISC acquisition, explore the potential roles of ISCs within cellular and viral replication complexes, and highlight critical gaps in our understanding of ISC delivery, coordination, and function among Fe-S proteins in large multi-subunit assemblies.}, }

Although force signals inherently fluctuate, the ability of skeletal muscles to generate accurate and steady force offers insights into the system's adaptability and its ability to adjust motor control strategies to meet task demands. This systematic review and meta-analysis aimed to synthesize evidence on quadriceps force control in individuals with anterior cruciate ligament (ACL) injury and/or surgical reconstruction (ACLR). Additionally, it sought to explore the relationship between force control measures and physical function outcomes.<br><br>METHODS: A literature search was conducted across several databases, including PubMed, EMBASE, Scopus, Web of Science, and SPORTDiscus. Risk of bias was assessed using the adapted Newcastle-Ottawa tool. The study included individuals with unilateral ACL injury and/or ACLR, with comparisons to uninjured controls or unaffected contralateral limbs. Primary outcomes included torque quality, force accuracy, and force/torque steadiness, while secondary outcomes included function-related clinical questionnaires and performance tests. Eligible studies consisted of observational studies and baseline data from interventional studies published in English. Standardized mean differences (SMDs) were calculated using a random effects meta-analysis.<br><br>RESULTS: A total of 33 studies were included, comprising 20 individuals with ACLR, 12 with ACL injuries, and one with both. The meta-analysis showed significant effects of ACL injury (SMD&#x2009;=&#x2009;0.84) and ACLR (SMD&#x2009;=&#x2009;1.57) on quadriceps torque frequency content. Individuals with ACLR had a greater root mean squared error (RMSE) or absolute error (AE) in force output compared to healthy controls (SMD&#x2009;=&#x2009;0.35) and exhibited a significant difference in the coefficient of variation (CoV) of the force signal (SMD&#x2009;=&#x2009;0.22), indicating impaired force control in those with ACLR.<br><br>CONCLUSIONS: ACL injury impairs quadriceps force control in the injured limb, as shown by torque frequency content analysis. While ACL reconstruction is the gold standard for joint stability, it may not fully restore neuromuscular function, potentially compromising physical functioning.

This review synthesizes evidence on the landscape of pediatric RSV co-infections in this transformed post-pandemic context. RSV co-infection is frequent, with human rhinovirus (HRV) being the most common viral co-pathogen and Streptococcus pneumoniae (Spn) and Haemophilus influenzae (Hi) predominating as bacterial co-infections. Critically, these co-infections are significantly associated with heightened disease severity, including more intense clinical presentations, prolonged hospitalizations, increased intensive care unit (ICU) admission rates, and greater therapeutic complexity. The relaxation of non-pharmaceutical interventions has been linked to a rebound in co-infection rates. While advances in molecular diagnostics have improved detection, and new prophylactics like nirsevimab offer promise, significant challenges remain. These include gaps in understanding pathogenic synergies, inequities in access to novel interventions, and the need for strategies to manage the ongoing evolution of RSV epidemiology. This underscores the necessity for enhanced surveillance, equitable prevention, and targeted research to mitigate the substantial burden of pediatric RSV co-infections.}, }

However, the expanding toolkit of VLP engineering strategies-spanning genetic fusion, modular conjugation, and nucleic acid encapsulation-creates a critical need for a rational selection framework to match technological strengths with specific vaccine objectives. This review addresses this gap by constructing a comparative decision-making framework centered on four core engineering dimensions: cargo flexibility, loading specificity, functional efficiency, and manufacturability. We systematically juxtapose two principal technology streams: (1) the display of protein antigens (through genetic, chemical, and bio-conjugation) and (2) the encapsulation of nucleic acid cargo (via physical, electrostatic, and programmable packaging mechanisms), evaluating each within this unified framework. This technological dissection is directly linked to the development landscape of VLP-based vaccines against major pathogens-including HBV, HPV, malaria, influenza, and SARS-CoV-2-illustrating how strategic choices at the engineering level fundamentally underpin immunogenic potency and translational success. By sequentially considering immunological objectives, antigen compatibility, surface display modality, interior cargo integration, and manufacturing constraints, this framework facilitates rational, stepwise VLP vaccine design. Looking forward, we discuss emerging trends toward modular and computationally guided platforms for antigen placement and scaffold design. By integrating a structured technology assessment with translational insights, this review aims to provide a practical roadmap for the rational design and accelerated development of next-generation, broadly protective VLP-based vaccines.}, }

The current treatment approaches include both endocrine monotherapy and combinational strategies incorporating targeted signaling pathway inhibitors. Despite recent therapeutic advances that have significantly improved patient outcomes, the development of resistance to endocrine therapies leads to relapses and treatment failure. Emerging evidence has shown that long non-coding RNAs (lncRNAs) are therapeutic modulators; however, their involvement in clinical studies has not been much explored. In HR+ breast cancer, lncRNAs influence both sensitivity and resistance to endocrine therapy by modulating estrogen receptor (ER) function, switching between alternative survival pathways, and altering tumor epigenetics and tumor microenvironment. The major focus of this comprehensive review is to understand the role of lncRNAs in overcoming the endocrine resistance issues in the treatment of HR+ breast cancer. It presents a comprehensive approach focused on endocrine therapy mechanisms, resistance, and adaptive escape pathways of HR+ tumor cells. By mapping these mechanisms of endocrine therapy, the review reveals novel therapeutic targets for the treatment of HR+ breast cancer. Lastly, it highlights the specialized lncRNA-based therapeutics for bone metastatic niches in HR+ breast cancer and current approaches of therapeutic targeting of lncRNAs for disease treatment.}, }

Social media mining (SMM) enables real-time monitoring of user-reported health information and serves as a supplement to traditional health data analytics. However, the rapid proliferation of literature has produced fragmentation, and a comprehensive knowledge map regarding SMM is lacking. Further, existing bibliometric reviews in health fields are easily undermined by synonym fragmentation and parameter settings, reducing their robustness. Thus, a more robust, reproducible, and decision-oriented bibliometric framework is required.<br><br>OBJECTIVE: This study aimed to (1) outline key thematic clusters in health-related SMM and map their dynamic evolution, and (2) methodologically demonstrate how machine learning-based bibliometric analysis can strengthen the robustness, transparency, and foresight capacity of evidence synthesis.<br><br>METHODS: This study designed a fully automated and reproducible bibliometric analysis of PubMed journal articles published from 2015 to 2025 (n=250) and analyzed records with both abstracts and keywords (n=189). We performed cleaning and standardization for titles, abstracts, author keywords, and MeSH terms, and carried out an exploratory descriptive analysis to obtain preliminary insights into publication patterns. Subsequently, we used SPECTER2 and PubMedBERT embeddings with keywords and abstracts to construct a hybrid similarity matrix. Then, we applied Uniform Manifold Approximation and Projection for dimensionality reduction, followed by Hierarchical Density-Based Spatial Clustering of Applications with Noise for thematic clustering, and visualized the results in a 3D strategic coordinate system (maturity, influence, and recency). We performed intercluster relationship analysis and time-slice analysis to examine thematic intersections and evolution. To ensure robustness and enhance interpretability, we implemented dual-level validation.<br><br>RESULTS: We identified 6 thematic clusters: cluster 1 (candidate incubator pool of peripheral cross-cutting topics in health-related SMM), cluster 2 (computational methods in health informatics), cluster 3 (public attitudes and sociopsychological determinants), cluster 4 (infodemiology and the COVID-19 information ecosystem), cluster 5 (health communication and public health engagement), and cluster 6 (social media analysis and network methods). Strategic 3D mapping revealed that methodological clusters (clusters 2 and 6) occupied high-maturity and high-influence positions, while application-driven clusters (clusters 3 and 4) occupied high-influence and high-recency positions, representing rapidly expanding frontiers. Clusters 1 and 5 demonstrated strong potential for further growth. Temporal slicing confirmed a trajectory moving from methodological consolidation and thematic diversification to a renewed focus on convergence and problem-solving. Validation showed strong semantic coherence and robustness of the methods and findings.<br><br>CONCLUSIONS: We developed a semantic-structural hybrid bibliometric framework with dual-level validation, reducing synonym fragmentation and parameter sensitivity inherent in traditional approaches.

Non-pharmacological measures-hydration, nasal saline irrigation, and avoidance of irritants-remain the first-line management. Pharmacological therapy may be considered in selected cases where cough is particularly distressing or significantly interferes with sleep; peripherally acting, nonsedative antitussives represent a reasonable option in terms of efficacy and safety. Centrally acting antitussives and unnecessary antibiotics should be avoided. Standardized, high-quality natural medical devices-with appropriate supporting evidence-represent a valid option. Honey-based preparations can be considered as complementary options. The paper also discusses new insights into cough pathophysiology, particularly the role of airway sensory hypersensitivity and neurogenic inflammation, which are paving the way for mechanism-based treatments.<br><br>CONCLUSIONS: This position paper provides an updated, pragmatic framework for the management of acute and post-viral cough in children and adolescents.

Asthma prevalence increases with body mass index, demonstrating distinct phenotypes including atopic, insulin-resistant, dyslipidemic, and non-Th2 neutrophilic subtypes. OSA affects 22% of men and 17% of women, with obesity being the principal modifiable risk factor. OHS occurs in 8-20% of obese patients with sleep-disordered breathing, characterized by daytime hypercapnia (arising from impaired neuromuscular ventilatory drive and progressive nocturnal hypoventilation) and increased cardiovascular mortality. Paradoxically, obesity appears protective in advanced COPD by reducing FRC, thereby increasing inspiratory capacity and limiting dynamic pulmonary hyperinflation, and ARDS-the so-called obesity paradox-while conferring increased risk in COVID-19 pneumonitis. In lung cancer, obesity demonstrates complex relationships with risk and prognosis that vary by sex, smoking status, and disease stage.<br><br>CONCLUSIONS: Obesity-related respiratory disorders represent a multifaceted clinical challenge requiring integrated multidisciplinary approaches.

Of these, 36 RCTs (20,798 participants) compared CP to placebo or standard care, five (604 participants) to standard plasma, and one (190 participants) to human immunoglobulin. In the full review, we performed subgroup analyses by antibody detection, time since symptom onset, country income level, and key comorbidities. Convalescent plasma versus placebo or standard care alone CP does not reduce all-cause mortality at up to day 28 (risk ratio (RR) 0.96, 95% confidence interval (CI) 0.90 to 1.03; 31 RCTs, 20,798 participants; high-certainty evidence). It has little to no impact on the need for invasive mechanical ventilation, or death (RR 1.03, 95% CI 0.98 to 1.08; 8 RCTs, 15,189 participants; high-certainty evidence) and has no impact on whether participants are discharged from hospital (RR 1.00, 95% CI 0.97 to 1.02; 9 RCTs, 13,930 participants; high-certainty evidence). CP may have little to no impact on QoL (MD 1.00, 95% CI -2.14 to 4.14; 1 RCT, 483 participants; low-certainty evidence). CP may have little to no impact on the risk of grade 3/4 adverse events (RR 1.17, 95% CI 0.96 to 1.42; 6 RCTs, 2392 participants; low-certainty evidence). It probably has little to no effect on the risk of serious adverse events (RR 1.19, 95% CI 1.02 to 1.38; 11 studies, 5298 participants; moderate-certainty evidence). Convalescent plasma versus standard plasma The evidence is uncertain about whether CP reduces all-cause mortality at up to day 28 (RR 0.77, 95% CI 0.53 to 1.10; 5 RCTs, 604 participants; very low-certainty evidence) and whether it increases the need for invasive mechanical ventilation, or death (RR 5.59, 95% CI 0.29 to 108.38; 1 study, 34 participants; very low-certainty evidence). The evidence is uncertain about whether convalescent plasma reduces or increases the risk of grade 3/4 adverse events (1 RCT, 248 participants). The evidence is also uncertain about whether CP reduces the risk of serious adverse events (RR 0.82, 95% CI 0.57 to 1.17; 4 RCTs, 447 participants; very low-certainty evidence). No studies in this comparison reported clinical improvement or QoL. Individuals with a confirmed diagnosis of SARS-CoV-2 infection and mild disease Six RCTs investigated the use of CP for 2761 participants with mild disease. Four RCTs (1164 participants) compared CP to placebo or standard care alone, and two (1597 participants) to standard plasma. Convalescent plasma versus placebo or standard care alone The evidence is uncertain about whether CP reduces all-cause mortality at up to day 28 (odds ratio (OR) 1.24, 95% CI 0.33 to 4.60; 3 RCTs, 1004 participants; very low-certainty evidence) and admission to hospital or death within 28 days (RR 0.45, 95% CI 0.04 to 4.81; 2 RCTs, 493 participants; very low-certainty evidence). It may have little to no impact on time to COVID-19 symptom resolution (hazard ratio (HR) 1.05, 95% CI 0.85 to 1.30; 1 RCT, 376 participants) and on the risk of grade 3/4 adverse events (RR 1.29, 95% CI 0.75 to 2.19; 1 RCT, 376 participants), both with low-certainty evidence. The evidence is uncertain about whether CP has an impact on the risk of serious adverse events (RR 0.84, 95% CI 0.56 to 1.26; 2 RCTs, 494 participants; very low-certainty evidence). No studies in this comparison reported other critical outcomes. Convalescent plasma versus standard plasma The evidence is uncertain about whether CP reduces all-cause mortality at up to day 28 (RR 0.41, 95% CI 0.05 to 3.06; 2 RCTs, 1597 participants; very low-certainty evidence). It probably reduces admission to hospital or death within 28 days (RR 0.50, 95% CI 0.32 to 0.78; 2 RCTs, 1597 participants; moderate-certainty evidence). CP may have little to no effect on initial symptom resolution at up to day 28 (RR 1.12, 95% CI 0.82 to 1.54; 1 RCT, 416 participants; low-certainty evidence). Neither study in this comparison reported other critical outcomes.<br><br>AUTHORS' CONCLUSIONS: Compared with placebo or standard care, high-certainty evidence shows that CP does not reduce mortality in individuals with moderate to severe disease and has little to no effect on clinical improvement or worsening. CP probably has little to no effect on serious adverse events. Publication of ongoing studies might resolve some of the uncertainties around CP therapy for people with asymptomatic or mild disease.

These drugs work by blocking two enzymes, COX-1 and COX-2, which regulate the production of prostaglandins, mediators involved in pain, fever, and inflammation. Corticosteroids (CSs) are commonly used in outpatient settings for anti-inflammatory purposes in the treatment of infectious diseases. However, their potential side effects, such as immunosuppression and increased metabolism, can be overlooked, even at low doses. Their use is clearly defined for severe conditions. Other infections, such as community-acquired pneumonia, pharyngotonsillitis, or otitis, do not have supportive data for the use of systemic CSs. For COVID-19, CSs are beneficial for severe cases that require ventilation, while they may not be helpful in mild cases. Infection-induced inflammation is associated with oxidative stress, a condition that arises from an imbalance between reactive oxygen species (ROS) and inadequate antioxidant responses. This stress worsens inflammatory reactions and can lead to severe respiratory infections and tissue damage. Managing oxidative stress is crucial in treating respiratory infections, and both CSs and NSAIDs can help reduce it. NSAIDs are preferred for treating symptoms such as fever and pain during the early phases of infections, especially viral ones, without hindering the immune response. CSs are powerful anti-inflammatory medications that are useful for treating infections in patients with asthma or allergies. However, CSs are not recommended for relieving pain and fever and can weaken the immune response. Both NSAIDs and steroids can mask serious infections, so doctors must be cautious in their use.}, }

Analysis was limited to studies conducted since December 2021 that performed an adjusted multivariate analysis. Quality was assessed using the Newcastle-Ottawa Scale. Summary estimates of adjusted relative risks (aRR) with 95% confidence intervals (CI) and prediction intervals (PI) were calculated overall and for prespecified subgroups. Heterogeneity was summarized visually and with &#x3c4; and 95% PIs. Absolute effects were estimated by applying pooled aRRs to baseline risks to obtain absolute risk reductions (ARRs) and numbers needed to treat (NNTs).<br><br>RESULTS: Forty-seven studies (10,791,211 patients) were included. Pooled aRRs were 0.54 (95% CI, 0.43-0.68) for all-cause hospitalization and 0.45 (0.36-0.56) for COVID-19 hospitalization. Pooled RRs were 0.30 (0.23-0.39) for all-cause mortality and 0.43 (0.32-0.59) for COVID-19 mortality. PIs were&#x2009;<&#x2009;1.0 for COVID-19 hospitalization (0.21-0.96), all-cause mortality (0.11-0.83), and any mortality (0.13-0.88), indicating likely benefit in future studies in similar settings. Subgroup analyses showed larger effects earlier in the Omicron period for hospitalization (RR 0.46 vs 0.68; p&#x2009;=&#x2009;0.0049) and the composite outcome (0.45 vs 0.68; p&#x2009;=&#x2009;0.0078), and a smaller mortality reduction among immunocompromised patients (RR 0.26 vs 0.11; p&#x2009;=&#x2009;0.034). The estimated NNT to prevent a COVID-19 hospitalization for patients at low risk (0.16%), moderate risk (2.2%), and high risk (8.9%) of hospitalization based on a validated risk score were 1148, 84, and 20 respectively.<br><br>DISCUSSION: N-R is associated with reduced hospitalization and death.

In the healthcare industry, it simultaneously accelerates innovation and increases systemic vulnerabilities. This study aims to review and conceptually synthesise the main channels of impact: (1) pharmaceuticals, clinical development, and regulation; (2) supply chains and resilience; (3) service mobility (health tourism); (4) human resources and competencies; (5) digitalization, artificial intelligence (AI), and data governance; (6) ethics, law, and public policy; and (7) sustainability and climate change. The COVID-19 pandemic highlighted the risks associated with global interdependencies, particularly in supply chains, while also demonstrating the innovation-accelerating effects of knowledge sharing and international cooperation. Particular attention is given to artificial intelligence and digital health, which open up new potential for efficiency and quality improvement from research and development through diagnostics to healthcare organization, while simultaneously intensifying concerns related to data protection, cyber security, and liability. Telemedicine, platform-based systems, and real-world data may contribute to addressing the care needs of ageing societies, but only when supported by appropriate competencies and sound data governance. As global data flows intensify, the importance of data protection, bias mitigation, transparency, and accountability correspondingly increases. Through the cultural channels of globalization, health-conscious lifestyles and complementary approaches are also spreading, which we address in a brief, separate subsection. The guidelines of international organizations foster standardization; however, due to differences in local capacities and institutional environments, the effects are not homogeneous. In conclusion, the study emphasises the dual nature of globalization; it expands access and accelerates innovation, while at the same time creating new vulnerabilities-in supply chains, labour mobility, and data security-and, together with climate-related risks, generating complex adaptive pressures for the healthcare industry.}, }

As a key platform for gene therapy vectors, elucidating HAdV's virulence factors is vital for optimizing therapeutic applications and mitigating risks. To achieve productive replication, HAdV strategically neutralizes host immune defenses and induces S-phase pathways essential for viral propagation. This review synthesizes the latest insights into the key pathways through which HAdVs harness these early proteins to enhance virulence, skilfully evading and counteracting host defense mechanisms while propelling viral replication. As foundational platforms for gene therapy vectors (e.g., in oncology and rare disease treatments) and vaccine backbones (e.g., COVID-19 vaccines like ChAdOx1), understanding HAdV's immunoshadowing-the multifaceted strategies used to cloak innate and adaptive immunity-is crucial for enhancing vector safety and efficacy. Recent insights unveil how early viral proteins-including E1A, E1B-55K, E4orf1, E4orf3, E4orf6, and the E3 complex-participate in these processes. This review critically synthesizes these pathways, evaluating study limitations such as reliance on immortalized cell lines that underestimate the role of these proteins in immunological competent cells, and addresses unresolved controversies, including differential immunoshadowing efficacy across HAdV species that impacts vaccine design.}, }

Patients frequently report chronic neurocognitive disorders such as brain fog, significant attention deficits and increased susceptibility to epileptiform discharges. The aim of this review is to systematize the knowledge regarding deviations in quantitative electroencephalography (QEEG) recordings in convalescents and to evaluate the utility of this method as an objective biomarker. This work constitutes a comprehensive literature review integrating the latest data on neuroinflammation, blood-brain barrier damage and changes in cortical oscillatory dynamics induced by the infection. The literature analysis indicates that the virus may induce a pathological excitation and inhibition imbalance (E/I imbalance) in neuronal networks. In QEEG studies this manifests as excessive activity of slow bands (Theta, Delta), a deficit of rhythms responsible for attention and sensorimotor integration (SMR) and a pathologically elevated Theta to Beta ratio (TBR). In conclusion, QEEG can serve as an objective and highly sensitive tool supporting the diagnosis and stratification of patients with neurocognitive complications of Long COVID. The integration of precise electrophysiological phenotyping with targeted behavioral neuromodulation (e.g., EEG-Biofeedback) fits into the paradigm of personalized medicine and offers a prospective strategy for mitigating long-term neurological burdens.}, }

This narrative review examines both classical and contemporary computational approaches used for measles monitoring, prediction, and control, with particular attention given to the emerging role of artificial intelligence (AI). We synthesized findings from 46 studies; 31 focused directly on measles and 15 on methodologically relevant studies from related infectious diseases (COVID-19, influenza, malaria), selected through searches of PubMed, Scopus, Web of Science, IEEE Xplore, and preprint servers, conducted between June and December 2025. Traditional compartmental models (SIR, SEIR, MSEIR), statistical tools (ARIMA, SARIMA), and seroepidemiological analysis provide transparent, well-characterized frameworks for estimating transmission dynamics and simulating intervention scenarios. Spatial modeling, network analysis, and Monte Carlo simulations have added geographic granularity to outbreak characterization. More recently, AI and machine learning (ML) methods, including supervised algorithms (Random Forest, XGBoost, SVM), deep learning architectures (CNN, LSTM), and hybrid mechanistic ML models, have shown improved predictive performance by integrating multiple data sources: epidemiological records, demographic profiles, mobility patterns, and behavioral indicators. AI-based approaches appear most valuable for high-dimensional risk prediction and image-based diagnostic tasks, while classical models retain clear advantages for policy-oriented scenario analysis. However, no AI-based or hybrid model identified in this review has been adopted into routine national measles surveillance or used for vaccination policy decisions at scale. Important challenges remain: data quality varies across settings, model generalizability cannot be assumed, and computational infrastructure disparities limit deployment in high-burden regions. Explainable AI, federated learning, workforce training for model interpretation, and integration of vaccination registries with mobility and genomic surveillance data represent concrete future directions for strengthening computational support for measles elimination.}, }

A well-established finding is sympathetic hyperactivity with reduced vagal tone, typically interpreted as autonomic nervous system dysfunction. Emerging evidence, however, suggests a broader disturbance across multiple neurotransmitter systems. This paper reviews current knowledge on neurotransmitter systems implicated in ME/CFS and Long COVID, focusing on potential mechanisms of dysregulation and their roles in disease pathology and symptom generation, as well as implications for treatment. In addition to abnormalities of the noradrenergic system, disturbances in serotonergic, GABAergic, and glutamatergic signaling have been reported. Contributing factors may include autoimmunity, neuroinflammation, gut dysbiosis, epigenetic influences, and stressors such as orthostatic intolerance, metabolic strain, and pain. A shift favoring excitatory over inhibitory neurotransmission can lead to excessive neural activation, autonomic dysfunction, sensory hypersensitivities, sleep disturbances, and cognitive impairment. Reduced GABAergic tone combined with increased glutamatergic and noradrenergic activity may elevate skeletal muscle tone, contributing to calcium overload, mitochondrial dysfunction, exertional intolerance, and post-exertional malaise. Various pharmacological treatments may partially rebalance these neurotransmitter systems, but limited efficacy highlights the need for systematic investigation and individualized strategies.}, }

During the COVID-19 pandemic, nursing care in some countries faced more challenges. One of these challenges was missed nursing care. This scoping review aims to identify and map the factors influencing missed nursing care in hospital settings during the COVID-19 pandemic in studies conducted in developed and developing countries.<br><br>METHODS: A scoping review was conducted according to methodology recommended by the Joanna Briggs Institute (JBI). We searched five databases-PubMed, Scopus, CINAHL, ProQuest, and Web of Science-as well as the Google Scholar search engine, from December 2019 to July 2025. Keywords of the study were selected according to the Medical Subject Headings (MeSH) and previous research. We included studies in hospital wards that examined missed nursing care and related concepts, specifically those whose data collection periods occurred during the COVID-19 pandemic. Language restrictions were not applied. The factors were derived inductively, considering conceptual similarities, relevance to the core themes, and similarities in meaning, including aspects related to the missed nursing care model, the developed model derived from it related to the factors considered for missed nursing care, and emerging challenges introduced by COVID-19. Findings were reported following the PRISMA-ScR.<br><br>FINDINGS: From the 1966 studies, we included 57 articles in the final review. Among them, 50 were cross-sectional, four were qualitative, two were mixed, and one was quasiexperimental. They were conducted mainly in Iran and the hospital units. Four main themes and nine subthemes emerged (1) work environment (structure, work climate), (2) nurse characteristics (individual and professional, personal), (3) workflow characteristics (intensity, predictability, risk), (4) country (developed, developing). Although the lack of human resources was reported in most studies, it was not the most significant contributing factor.<br><br>CONCLUSION: These findings can inform the development of strategies to address underlying factors affecting workflow, such as nurses' attitudes and the work environment, thereby enhancing adaptability to future global health crises and serving as a crucial policy foundation for mitigating the missed nursing care during health emergencies.<br><br>PRACTICAL IMPLICATIONS: These findings not only complement other global research exploring the reasons behind missed cares in nursing but also offer a framework for understanding and anticipating reported instances of missed care, enabling targeted interventions to address them effectively.}, }

First, to identify trends in research on facemasks and voice production, including thematic clusters and patterns, using bibliometric methods. Second, critically appraise and synthesize findings from primary research studies on the effects of facemask use on voice-related outcomes through a systematic literature review. Third, to determine the pooled effects of facemask use on selected vocal outcomes, where data allow, using meta-analysis.<br><br>RESULTS: In total, 48 publications were included in this review. The term co-occurrence network map generated with VOSviewer showed three clusters: voice-related consequences of mask use during the COVID-19 pandemic,&#xa0;the impact of protective equipment on speech acoustics and intelligibility,&#xa0;and acoustic markers of voice quality in healthy speakers. The overlay visualization map showed that earlier studies emphasized the subjective assessment of the relationship between facemasks and voice production. In contrast, more recent publications reflect a growing interest in the instrumental assessment of the relationship. Most studies based their results on voice acoustic analysis, followed by questionnaires and aerodynamic assessment. The results suggested no significant differences in fundamental frequency, jitter, shimmer, harmonics-to-noise ratio, and maximum phonation time. The results on vocal effort and sound pressure levels are inconsistent. The meta-analysis suggested that facemasks cause a small increase in SPL, but the effect was not statistically significant.<br><br>CONCLUSION: Facemasks create complex communication challenges that extend beyond acoustic changes to encompass multimodal perception disruption and disproportionate impacts on vulnerable populations. While acoustic measurements show minimal direct effects, the elimination of visual speech cues and facial expression recognition may create substantial barriers for individuals with hearing impairments, developmental disabilities, and age-related communication difficulties.}, }

Terms such as hygiene, modes of infection, community spread, quarantine, vaccines, etc. have become part of our daily conversations. As this book's first chapter provided a basic review of proteomic technologies for virologists, this chapter provides a basic review of virology for proteomic scientists. While virologist may find this chapter unsatisfying, hopefully proteomic scientists will learn enough to be able to understand how proteomic technology can be used to further detail the structure, function, and life cycle of viruses.

Pharmaceutical companies and government organizations learned to efficiently work together to produce and distribute vaccines in record time. Although it may have generated controversy, the value in getting vaccinated was revalidated. There were other things that the world learned, although it was not as obvious. The effect of vaccination rate on preventing virus mutation became evident during the pandemic. The original SARS-CoV-2 virus that started the pandemic mutated several times over the course of the pandemic. One thing that became clear during the pandemic was the lack of knowledge on how SARS-CoV-2 infection would affect individuals during the course of the disease. This inability to accurately prognose the disease made it difficult to personalize treatments for specific individuals and the distribution of resources to protect the most vulnerable populations challenging. What is required to increase the accuracy of prognosis is more knowledge about how dynamic changes occur within the host cell during viral infection. Since many proteins become dysregulated during infection, proteomics is a prime technology for gaining this knowledge to increase prognostic capabilities and enable personalized treatments that alleviate the suffering viruses cause on humanity.}, }

This seemingly logical answer, however, does not truly capture the diversity of the human organism. Over the past couple of decades scientists have discovered that humans are a collective of cohabitating human, bacteria, and fungi cells along with countless numbers of viruses. Collectively, these microorganisms are referred to as the microbiome (Lederberg and McCray, The Scientist 15:8, 2001). The most recent estimates suggest the biological material from these microorganisms makes up as much as half of every human. Considering the size of the microbiome, it is not surprising that humans share an intimate relationship with viruses since they will be found wherever life exists.}, }

Besides learning about messenger RNA (mRNA) vaccines, N95 masks, and coronaviruses (CoVs), we became familiar with the term pandemic. Pandemics are not novel. There have been approximately 250 pandemics recorded throughout history since 1200 B.C. with approximately 20 of these resulting in the deaths of more than one million people (https://study.com/learn/lesson/pandemics-in-history.html ; Sampath S et al., Cureus 13:e18136, 2021). The earliest recorded pandemic for which there is detailed information is the Justinian plague (Drancourt M and Raoult D, Clin Microbiol Infect 22:911-915, 2016). This pandemic began in 540 A.D., lasted for two centuries, and was a major factor that hastened the fall of the Roman Empire. So what exactly is a pandemic? At its most basic a pandemic is a disease that is simultaneously occurring worldwide, affecting many individuals. This definition does not include anything about the severity of the disease or the population's immunity. While most people would say that pandemics and epidemics are extremely rare, there have been six just in the last two decades (Bhadoria P et al., J Family Med Prim Care 10:2745-2750, 2021). These include the severe acute respiratory syndrome coronavirus 1 (SARS-CoV-1), swine flu, Middle Eastern respiratory syndrome CoV infection, Ebola virus, Zika virus, and the most recent SARS-CoV-2 pandemic (see Table 9.1).}, }

While its safety and efficacy are well established in adults, data in pediatric populations remain limited and are largely extrapolated from adult studies. Therefore, we aimed to assess the clinical outcomes and safety of RDV in pediatric patients.<br><br>METHODS: We performed a systematic review and meta-analysis of studies evaluating RDV in hospitalized children under 18 years with COVID-19. The primary outcomes were in-hospital mortality and the level of respiratory support (baseline and highest). The secondary outcome was the safety profile of RDV identified by adverse events and treatment discontinuation. Meta-analysis was performed only on patients who received RDV.<br><br>RESULTS: From 1298 records, 16 studies were included. A total of 722 patients who received remdesivir were included in this study. Pooled analysis at admission showed that 28% of patients required no oxygen, 23% needed low-flow oxygen, 21% needed high-flow oxygen, 11% required non-invasive ventilation (NIV), and 9% were treated with mechanical ventilation (MV). During hospitalization, the highest respiratory support required was no oxygen in 27%, low-flow oxygen in 33%, high-flow oxygen in 32%, NIV in 5%, and MV in 19%. Overall mortality was 2% (95% CI: 0.00, 0.04, I[2]&#x2009;=&#x2009;59.81%, p&#x2009;<&#x2009;0.001). The most frequent RDV-related adverse events were elevated ALT in 11% (95% CI: 0.00, 0.42, I[2]&#x2009;=&#x2009;94.02%, p&#x2009;<&#x2009;0.001), increased AST in 10% (95% CI: 0.00, 0.41, I[2]&#x2009;=&#x2009;94.56%, p&#x2009;=&#x2009;<&#x2009;0.001), unspecified liver enzymes elevation in 8% (95% CI: 0.01, 0.20, I[2]&#x2009;=&#x2009;81.84%, p&#x2009;<&#x2009;0.001), and hypertension in 10% (95% CI: 0.00, 0.58, I[2]&#x2009;=&#x2009;97.16%, p&#x2009;<&#x2009;0.001). Bradycardia (3%) and increased creatinine (2%) were also reported.

The COVID-19 pandemic raised concerns that maternal SARS-CoV-2 infection and associated factors, such as fever, inflammation, and psychosocial stress, might elevate teratogenic risk. This systematic review aims to synthesize the evidence on the association between maternal COVID-19 exposure and nonsyndromic CFAs in neonates. We conducted a systematic review in accordance with the PRISMA 2020 guidelines. Major electronic databases (PubMed/MEDLINE, Embase, Web of Science, Cochrane Library, and the WHO COVID-19 Database) were searched from their inception until February 2025. We included studies examining the association between documented maternal COVID-19 infection (before or during pregnancy) and the incidence, type, or severity of CFAs, with a focus on nonsyndromic orofacial clefts (NSOFC). Risk of bias of the studies was assessed using the ROBINS-I tool. Findings were synthesized narratively, and bibliometric analyses, including geo-mapping and conceptual structure mapping, were performed. Eleven studies met the inclusion criteria. The evidence was mixed: smaller regional studies suggested a possible link, particularly with first-trimester infection, which aligns with the critical timing of craniofacial development. However, large-scale, robust epidemiological and registry-based studies from the USA and Nordic countries consistently found no significant association between maternal COVID-19 infection and congenital anomalies. A meta-analysis could not be performed due to study heterogeneity. Maternal stress and fear of COVID-19 were repeatedly highlighted as potential factors, in some cases showing stronger or even paradoxical associations than the infection itself. Research activity was concentrated primarily in Saudi Arabia and the United States. Robust population-level evidence does not currently support a direct, major causal link between maternal SARS-CoV-2 infection and NSOFC. While a modest or context-specific association cannot be entirely excluded, the effects of maternal psychosocial stressors and restricted healthcare access during the pandemic appear to be important explanatory factors that warrant further investigation, independent of the viral infection itself.}, }

SFTSV-induced immunosuppression during infection renders patients highly susceptible to invasive pulmonary aspergillosis. SFTS-associated pulmonary aspergillosis (SAPA) presents major therapeutic challenges and is linked to drastically worsened outcomes, including high mortality. This report aims to highlight the diagnostic and therapeutic challenges of SAPA and emphasize the value of early diagnosis using metagenomic next-generation sequencing (mNGS). CASE REPORT We report a case of a previously healthy 56-year-old male farmer admitted with SFTS. On hospital day 3, when only mild cough had begun, mNGS of both blood and sputum concurrently detected Aspergillus fumigatus alongside SFTSV. This very early, pre-radiographic diagnosis prompted immediate targeted therapy with voriconazole and favipiravir. Despite this, imaging showed progressive pulmonary infiltrates with cavitation. The clinical course was further complicated by severe acute respiratory syndrome coronavirus 2 co-infection, but the patient recovered with intensive care and was discharged on day 24. A review of 13 literature-reported SAPA cases revealed a mortality rate of 30.77% (4/13). CONCLUSIONS SAPA is a severe, rapidly progressive complication of SFTS with high mortality, typically emerging 1-2 weeks after onset. This case highlights the importance of early diagnosis using rapid methods such as mNGS and the need for timely antifungal intervention to improve patient outcomes. Early antifungal therapy in high-risk patients is crucial.}, }

In less than a year, COVID-19 vaccines were developed and distributed. However, global and national distribution efforts faced significant challenges in ensuring equitable access, particularly for vulnerable populations. Despite WHO guidelines for national vaccine allocation, governments encountered difficulties in vaccine allocation and prioritisation. While Indonesia's COVID-19 primary dose coverage surpassed 70%, disparities persisted both across and within provinces as well as among different population groups. Discussion about the definition of vulnerable population and who should be prioritised remains critical to preparing for future pandemics. This paper argues for the establishment of clear guidelines for national governments on the allocation of vaccines, enabling timely action in future pandemics to prevent avoidable deaths and disabilities. Robust governance and data also remain a key area to improve. Drawing on Indonesia's experience with COVID-19, this paper offers recommendations for vaccine allocation during a respiratory pathogen pandemic.}, }

This narrative review summarizes current evidence regarding the impact of the pandemic on sexual behavior, sexual function, and male reproductive health. A comprehensive literature search of recent studies and clinical reports was performed focusing on psychosexual wellbeing, erectile function, fertility, and healthcare access during and after infection or lockdown periods. Current evidence indicates that lockdown-related stress, anxiety, and depression were consistently associated with reduced sexual desire and frequency of sexual activity, as reported in predominantly cross-sectional, questionnaire-based studies conducted during lockdown periods, particularly among couples with children and non-cohabiting partners, whereas alternative sexual practices increased. Sexual activity generally recovered after restrictions were lifted. Emerging data suggest a possible association between COVID-19 and erectile dysfunction mediated by endothelial damage, hypogonadism, and psychological distress, while long-COVID symptoms may further worsen sexual function. Male fertility alterations related to inflammatory and oxidative stress pathways have also been reported. Overall, the pandemic primarily affected sexuality through psychosocial mechanisms, although potential organic effects of SARS-CoV-2 infection on erectile function and fertility cannot be excluded. This review provides an interdisciplinary synthesis of current evidence with a specific focus on clinically relevant urological implications, including erectile dysfunction and male reproductive health, which remain incompletely addressed in the existing literature.}, }

The workshop was structured around four key issues facing those working to improve dog health: 'Supply and Demand', 'Breeding for Health and Well-Being', 'Big Data', and 'Does the Colour Matter? Defining Breed vs. Variety'. The workshop provided an opportunity for participants to meet face-to-face after a five-year hiatus due to COVID-19, on the 10[th] anniversary of the International Partnership for Dogs. Among the 106 decision-makers from 16 countries who attended the workshop, there was broad agreement on several issues during the discussions, such as following the scientific evidence on canine genetics and health, moving away from extreme conformation, and using all available tools, including crossbreeding, to maintain and increase genetic variation within dog breeds. It was agreed that these principles should become priorities for welfare-minded organisations at the national and international levels. Better education of puppy buyers, breeders, show judges, and other relevant parties was recurringly identified as a priority across all four themes of the workshop.<br><br>CONCLUSIONS: In summary, key agreements from the 5th IDHW were that organisations must comply fully with relevant national animal welfare legislation, that organisations must work to eliminate extreme conformations from all dogs and to improve and maintain genetic diversity within subpopulations of dogs, and that organisations should recognise and support crossbreeding as an accepted and valuable tool for modern dog breeding.}, }

We assessed compliance with the 27 PRISMA-DTA items.<br><br>RESULTS: After screening 5252 publications, we included 38 reviews. We found no PRISMA-DTA item with a low reporting frequency. Regarding the number of items reported, 23 (60%) of the included studies reported over 66%, and 15 (40%) reported between 33% and 66%, with none reporting fewer than 33%. None of the included reviews complied with the full PRISMA-DTA checklist.<br><br>CONCLUSIONS: Our meta-epidemiological survey reveals persistent shortcomings in the reporting quality of systematic reviews evaluating rapid antigen test accuracy for SARS-CoV-2. While some items were consistently addressed, numerous critical domains requiring a deeper understanding of the specific diagnostic test accuracy assessment methods showed low reporting adherence.}, }

Established manufacturing methods, including microfluidic mixing and impingement jet mixing, have exhibited excellent scalability, reproducibility, and clinical relevance, most notably during the development of vaccines for SARS-CoV-2. Nevertheless, these techniques are accompanied by challenges related to the handling of organic solvents (ethanol), scalability for personalized medicine, and environmental considerations. This review draws attention to recent innovations in LNP formulation that seek to address these challenges through alternative and complementary approaches. One central focus of this review highlights post-formation encapsulation strategies, utilizing preformed vesicles or other nanostructures. These strategies facilitate modular, on-demand loading of nucleic acids. In addition, organic solvent-free techniques, including thermocycling, calcium-mediated DNA encapsulation, and aqueous sonication, offer new opportunities for biocompatible, streamlined manufacturing. In line with these formulation strategies, the review discusses recent progress in continuous manufacturing platforms, which enable end-to-end process control, real-time analytics, and increased production efficiency. By comparing conventional and emerging techniques, this review provides an overview of the evolving LNP formulation landscape and identifies key opportunities for integrating innovation into conventional production pipelines.}, }

This phenotype could lead to microcirculatory changes that decrease oxygen delivery to tissues because of loss of laminar flow, lack of nitric oxide dependent vasodilation, increased viscosity and abnormal constriction of vascular smooth muscle cells due to neuropathy. There are several ways of identifying patients with endothelial dysfunction and the most used is flow mediated dilation. Many randomized trials have already found significant treatments for endothelial dysfunction and include antihypertensives, statins, beta-blockers, supplements and lifestyle interventions.

The pandemic led to unprecedented increases in healthcare delivery costs, widespread disruption in medical supply chains, workforce instability, and a loss of typical inpatient caregiver support. These challenges affected all levels of care, from primary health services to highly specialized intensive care units (ICUs). Before vaccines were available, ICUs were overwhelmed by critically ill patients requiring mechanical ventilation, saturating capacity and straining staff.ObjectivesThis article seeks to examine the effect that COVID-19 had on ICUs globally, acknowledging its impact with an aim to identify solutions that can be used to help mitigate the overburdening of this limited resource in future pandemics.MethodsA narrative review approach was used, drawing on published literature, observational data, and institutional responses from 2020 to 2025, to analyze structural, operational, and clinical adjustments in ICU design and function.ResultsKey adaptations included physical redesigns, rapid infection-control upgrades, the use of negative pressure rooms, expansion of tele-ICU systems, and virtual family engagement strategies. These interventions were implemented to address ICU crowding, equipment shortages, and staff burnout, and helped to maintain continuity of care during surge conditions.ConclusionsThe COVID-19 pandemic demonstrated the need for ICUs to be more agile, scalable, and future-facing. Lessons learned highlight the importance of preparedness strategies that strengthen ICU resilience and support critical care delivery in future public health emergencies.}, }

The protocol for this systematic review was registered in the PROSPERO database (CRD42024497097). Literature searches in PubMed, Embase, Scopus, and Web of Science (WoS) identified 20,453 studies reporting respiratory viral testing in Europe over the past decade (2012/13-2022/23). Eligible studies were English-language full-text or grey articles with low risk of bias and complete data, and reports that explicitly provided the number of positive airway virus cases (n, virus) and the total infant population (N). Risk of bias was assessed using the Hoy et al. scoring system. Pooled prevalence estimates (pooled proportion [95% CI]) were calculated for pre-, during-, and post-COVID-19 periods using proportional meta-analysis with the MetaProp package in R. Fifty studies before, ten studies during, and 18 studies after the COVID-19 pandemic were eligible for proportional meta-analyses of viral testing in infants. Before the pandemic, the predominant viruses in infants with respiratory infections were Respiratory Syncytial Virus (RSV) (0.48 [0.41-0.56]), Human rhinovirus (HRV) (0.24 [0.18-0.29]), and Influenza virus (IV) (0.08 [0.04-0.12]).

Risk of Bias (RoB) was assessed using the ROBINS-I tool. Meta-analysis and multivariable meta-regression were conducted for studies addressing comparable population-intervention-comparator-outcome (PICO) questions.<br><br>RESULTS: We included 30 studies, comprising 35 design-specific analyses. We identified considerable variability in design elements including risk window length (7-288&#xa0;days), reference period timing (three different ways), and control for COVID-19 disease (five different approaches). Thirteen (37%) design-specific analyses had serious or critical overall RoB. We observed strongest heterogeneity between studies in general population for dose 2 of BNT162b2 and mRNA-1273 compared to unvaccinated individuals/reference period (I[2]&#xa0;=&#xa0;96%, prediction interval (PI) of relative risk 0.40-20.20; I[2]&#xa0;=&#xa0;92%, PI 1.23-88.63, respectively). Meta-regression for the former PICO indicated that after adjusting for age and sex, effect estimates of samples with 28-day risk window were 0.56 times (95% CI 0.43-0.72) lower than those with 7-day risk window, but its overall effect was not significant. The effect of study design, outcome definition, approaches to handle COVID-19 infection and overall RoB were not significant in the meta-regression.<br><br>CONCLUSIONS: There is substantial variation in study design specifications and corresponding heterogeneity in reported effect estimates. Design choices like risk window length may explain some of this heterogeneity, although evidence remains inconclusive. Future vaccine safety studies should include sensitivity analyses to explore the effect of design choices on their findings.}, }

The authors aim through this review to understand how much digital platforms such as JackTrip, Jamulus, Zoom, and Soundtrap have affected the student engagement in musical ensemble practice. The paper emphasizes virtually choreographed concerts not only as a method for being able to continue training when difficulties arise but also to develop creative cooperation, self-management, and more advanced group playing skills. Seventeen peer-reviewed articles from 2020 to 2025 show that low latency platforms such as JackTrip and Jamulus are instrumental in facilitating musical engagement in real-time. Along with this, by using constructivist pedagogical methods like project-based learning, flipped classrooms, and DIY/DIWO, students become relentlessly more creative with music. Tools like Soundtrap help students create ideas asynchronously, while real-time platforms support timing and listening skills. However, there are still problems besides these advantages. Latency, audio compression, the difference in the equipment, and complicated user interfaces make it difficult for everyone to participate equally and for the group to stay together. The review points out that the success of virtual ensemble learning depends on instruction supported by well-aligned technology, which means planning, scaffolding, and technical support as well as flexible roles. This study provides a framework for educators, curriculum developers, and institutions seeking to improve hybrid music education. The right technology with inclusive, reflective teaching, virtual ensembles can become great ways to work together creatively and perform well.}, }

A protocol was registered a priori (PROSPERO ID: CRD42024619193). Systematic searches of MEDLINE and EMBASE databases were conducted in November 2024 and supplemented by conference searches from 2022-2024. Population, Exposure, Comparisons, Outcomes (PECO) criteria were used to screen publications for inclusion. Critical appraisal tools published in the Joanna Briggs Institute (JBI) Handbook for Evidence Synthesis were used to assess the risk of bias of the primary studies included. The outcomes associated with Omicron variants, identified by sequencing or predominance periods, included hospitalization, admission to intensive care, death, and various composite endpoints.<br><br>RESULTS: Thirty-two studies fulfilled the eligibility criteria, most reported on relative disease severity for early Omicron BA.5 (n&#x2009;=&#x2009;23) and XBB (n&#x2009;=&#x2009;24) variants. Overall, COVID-19 severity appeared largely comparable across the various Omicron subvariants. Among the subset of studies that directly compared various severity outcomes to earlier SARS-CoV-2 variants (n&#x2009;=&#x2009;7), some reported modest increases or decreases in severity. However, these differences were generally not statistically significant. Five studies stratifying outcomes by the presence of comorbid conditions noted that comorbidities were predictors of significantly worse COVID-19 disease outcomes (p&#x2009;=&#x2009;0.000-0.027).<br><br>CONCLUSIONS: Overall, this systematic review found the severity of COVID-19 disease to be comparable among Omicron subvariants.

Despite advances in cardiac magnetic resonance imaging and molecular diagnostics, substantial uncertainty persists regarding early diagnosis, etiologic classification, and optimal therapeutic strategies. Current management relies largely on supportive care, as robust randomized evidence guiding immunomodulatory therapy remains limited and confined to selected virus-negative or autoimmune phenotypes. This review synthesizes contemporary evidence on the pathophysiology, diagnostic challenges, and treatment paradigms of acute myocarditis, with a particular focus on the critical distinction between virus-positive and virus-negative disease. We discuss established supportive and guideline-directed therapies, emerging immunomodulatory approaches-including corticosteroids, biologics targeting interleukin-1, complement, and mammalian target of rapamycin pathways-and the evolving role of mechanical circulatory support in fulminant myocarditis. COVID-19 vaccination-related myocarditis is highlighted as a modern example of immune-triggered, predominantly virus-negative myocarditis, illustrating both the generally favorable prognosis and the potential for severe clinical courses. Finally, this review outlines future directions toward precision immunocardiology, emphasizing the integration of endomyocardial biopsy, molecular virology, multi-omics profiling, and artificial intelligence-guided phenotyping to enable mechanism-driven, individualized therapy. Advancing from empirical management to precision-based intervention will be essential to improving outcomes in acute myocarditis.}, }

In pediatrics care in the United States (US), it has become an important approach to expand access to primary and subspecialty care while reducing travel demands and improving continuity of care, particularly for children in remote and underserved communities. Evidence consistently shows that telemedicine can supplement in-person visits while maintaining high levels of family satisfaction and clinical effectiveness among American families. This narrative review was developed to assess the applicability of telemedicine for new immigrant families in the US using a structured literature search across PubMed, Scopus, Google Scholar, and Cochrane of published English literature. Peer-reviewed studies were included if they were conducted in the last 50 years and focused on pediatric patients from birth to 21 years of age. Findings were synthesized to evaluate the acceptance, accessibility, feasibility, and applicability of telemedicine for new immigrant children in the US. Across the reviewed literature, telemedicine has meaningful potential in narrowing health disparities faced by new immigrant families such as transportation, specialist shortages, scheduling delays, limited English proficiency, and difficulty navigating the complex healthcare system. Furthermore, telemedicine can connect families with providers who share similar cultural and linguistic backgrounds, thereby strengthening cultural sensitivity and trust. Still, it comes with several obstacles limiting its use among new immigrant families. From digital divide, poor network coverage, low health literacy, privacy concerns, immigration-related concerns, to mistrust, the challenges are numerous. Studies during the COVID-19 pandemic found low acceptance and infeasibility of telemedicine for new immigrant families. However, telemedicine offers multiple opportunities and future directions to better serve immigrant children and their families. Expanding multilingual telehealth platforms and integrating telemedicine access points into schools, community centers, and immigrant resource hubs can enhance accessibility, usability, and acceptance. Pairing telemedicine with artificial intelligence can have huge future potential and might be a tool for inclusive care at lower cost. Furthermore, policy amendments, particularly broader Medicaid telemedicine coverage and mandates for interpreter integration into telemedicine workflows, are essential for promoting more equitable access with higher acceptance and more applicability for new immigrant children in the US.}, }

This scoping review systematically maps ML applications in zoonotic disease management to identify research trends, methodological approaches, and critical gaps across different epidemiological stages and functional domains. We organize the literature along two dimensions: epidemiological stages, from animal hosts to human populations, and functional domain, including diagnosis, epidemiology, and intervention. We searched PubMed and Web of Science for studies on 14 preselected high-priority zoonotic diseases. The search string combined keywords for the selected diseases, ML techniques, and functional applications (diagnosis, epidemiology, and intervention). A total of 966 studies were included in the final analysis, of which 72.8% focused on COVID-19. Our analysis shows robust ML performance in clinical diagnostics, epidemic forecasting, and intervention optimization within human populations. However, critical gaps persist, only 1.96% of studies examined the animal-human interface, no ML models explicitly targeted spillover prevention, and studies on animal-reservoir surveillance remain limited. All spillover studies originated from high-income or upper-middle-income countries (UMICs), in contrast with low- and lower-middle-income countries (LMICs) contributing 21.4% of human-stage studies. These findings reveal a pronounced mismatch between research investment and spillover risk and highlight the need for greater emphasis on spillover mechanisms, enhanced integration of cross-species transmission dynamics, and methods suitable for surveillance in resource-limited settings. Addressing these imbalances is essential for advancing a shift from reactive outbreak response to proactive spillover prevention within a One Health framework.}, }

Significant heterogeneity was driven by variations in follow-up duration and intravenous immunoglobulin (IVIG) prophylaxis rates (range: 41.8%-81.3%).<br><br>CONCLUSIONS: Teclistamab is associated with a substantial and cumulative infectious burden. The lower infection rates in RWE may reflect shorter follow-up and evolving prophylactic strategies. Standardized infection surveillance, including regular IgG monitoring and consideration of IVIG replacement in patients with low IgG levels, may help optimize the safety of BCMA-directed bispecific therapies.<br><br>https://www.crd.york.ac.uk/prospero/, identifier CRD420261297645.}, }

The long-acting monoclonal antibody nirsevimab has achieved durable, population-level protection against RSV in infants, reducing hospitalizations by 70-90% with no evidence of antigenic escape. In contrast, all neutralizing monoclonal antibodies against SARS-CoV-2 became obsolete within three years due to rapid viral evolution, particularly in the spike receptor-binding domain. This review dissects the mechanistic determinants underlying this divergence. We propose four key principles that govern antibody efficacy against respiratory viruses: (i) targeting a structurally conserved epitope with high fitness cost for escape; (ii) achieving sufficient antibody concentrations in the airway epithelial lining fluid; (iii) the vulnerability of single-epitope strategies against mutable viral targets; and (iv) the auxiliary but non-substitutable role of Fc effector functions. By comparing RSV and SARS-CoV-2, we illustrate how these principles align in successful interventions and fail in others. Finally, we discuss emerging strategies-particularly inhaled delivery and mRNA-encoded antibodies-that may overcome current limitations and enable durable protection against antigenically variable respiratory pathogens.}, }

This review focuses on several diseases representative of the IACI spectrum. These are post-treatment Lyme disease syndrome (PTLDS), long COVID, myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and multiple sclerosis (MS). Their clinical and biological complexity, combined with a lack of clear diagnostic criteria and objective available laboratory biomarkers, makes them difficult to distinguish from conditions with overlapping features. This presents challenges for research studies, as well as diagnosis and clinical management. This diagnostic ambiguity, coupled with heterogeneous patient presentations, has led to challenges in research, including misclassification of study participants and inconsistent or irreproducible findings. Some PTLDS research exemplifies these issues, which also extend to other IACIs. To advance the field, we highlight key methodological refinements and approaches for studying IACIs, including rigorous participant selection, standardized sample collection protocols, and the use of appropriate control groups, including those with microbiologic proof of the initial infection when known and technologically feasible. We also address broader influences on research quality, such as stigma, historical neglect, and the urgency to find treatments, which have contributed to the proliferation of poorly controlled studies and questionable practices. Drawing lessons from past challenges, we propose a path forward grounded in fit-for-purpose methodological rigour to improve scientific understanding and support evidence-based therapeutic development for IACIs.}, }

Repurposing existing medicines with known or potential antiviral activity offers a faster, cost-effective strategy to expand treatment options during public health emergencies. This scan aimed to map current investigational activity involving repurposed medicines for these viruses. A horizon scanning approach was employed, starting with a targeted search in Embase followed by a systematic search of ClinicalTrials.gov to identify developmental stages of relevant technologies. Eligible technologies included UK- or EU-licensed medicines being investigated for antiviral use, while vaccines, unlicensed medicines, and treatments already approved for the target viruses were excluded. From the literature, 196 repurposed technologies were identified, and the expanded search on the clinical trials registry revealed 58 technologies in active clinical development. Interventional trial activity was limited to influenza and SARS-CoV-2, with 29 technologies for SARS-CoV-2 and two influenza technologies advancing to phase III evaluation. For other viruses, candidate repurposed technologies were identified only at preclinical or exploratory stages. Frequently investigated pharmacological classes included direct-acting antivirals, immunomodulators, and anti-inflammatory agents. While repurposing represents a potentially rapid strategy for therapeutic deployment, inclusion in this horizon scan does not imply clinical efficacy.

However, it remains unclear which host factors are robustly engaged across independent Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) RNA interactome studies and to what extent these factors are shared with other RNA viruses. Here, we perform an integrative meta-analysis of eight published SARS-CoV-2 RNA-protein interactomes and compare them with corresponding Influenza A virus, Zika virus, and Dengue virus datasets to define conserved host networks and prioritize candidate host-directed antiviral targets. By integrating multiple datasets and applying ClusterProfiler together with curated pathway resources (KEGG, Reactome, WikiPathways, and Gene Ontology), we systematically characterize the functional landscape of SARS-CoV-2 RNA-protein interactions. The consensus SARS-CoV-2 interactome is enriched for mRNA processing, translation, RNA surveillance and innate immune functions. Cross-viral comparison identifies 275 host proteins shared across all four RNA viruses, forming interconnected modules that include key translation factors (EEF1A1, EIF4A1, EIF3H) and RNA-binding proteins (Nucleolin, ILF3). Drug-target annotation prioritizes 21 proteins with 35 approved or investigational modulators for host-directed antiviral repurposing.

Therefore, clinicians should be aware of all factors that may promote their occurrence, particularly those related to common viral infections such as influenza and SARS-CoV-2. Both influenza and SARS-CoV-2 utilize transferrin receptor 1 (TfR1) to enter host cells; notably, SARS-CoV-2 has been detected in tissues that do not express ACE2. TfR1 is highly expressed on cardiomyocytes, as well as on endothelial cells. Iron deficiency -a common disorder in the general population- promotes overexpression of TfR1, thereby facilitating the entry of SARS-CoV-2 and influenza viruses into cardiomyocytes and endothelial cells. Therefore, an increased expression of the TfR1 on cardiomyocytes may consequently contribute to the development of viral myocarditis, and atrial fibrillation. Finally, TfR1 is involved in viral uptake by endothelial cells and in molecular pathways implicated in thrombus formation. Clinicians should recognize that individuals with iron deficiency and concomitant SARS-CoV-2 or influenza infection may be at increased risk of arterial and venous thrombosis, atrial fibrillation, and viral myocarditis. Given that approximately two billion people worldwide have some degree of iron deficiency-especially older adults and young children-appropriate preventive strategies should be considered.}, }

This study conducted a systematic review and meta-analysis to establish the pooled prevalence of MRSA in Pakistan.<br><br>METHODS: We searched electronic databases (Google Scholar, PubMed, Embase) for studies published between 2015 and 2025. The PRISMA guidelines were followed to conduct this systematic review. Meta-analyses were performed using R Studio software, applying both fixed- and random-effects models to calculate pooled prevalence. The heterogeneity was assessed using the I&#xb2; statistics. Publication bias was assessed using Begg's and Egger's tests. Most studies used cefoxitin disk diffusion to characterize MRSA, while some studies used PCR to detect the mecA gene.<br><br>RESULTS: Sixty-eight studies meeting the inclusion criteria were analyzed. The overall pooled MRSA prevalence was estimated at 50% (95% CI: 45-54%), with I&#xb2; = 98.9). Year-wise subgroup analysis revealed significant variation from 2015 to 2025, with estimates ranging from 64% (95% CI: 26-90%), with I&#xb2; = 96.68 in 2022 to a low of 34% (95% CI: 17-56%), with I&#xb2; = 99.16 in 2020, which may be due to reduced healthcare access and infection control measures implemented during the COVID-19 lockdowns. The pooled estimate among general patients and healthcare personnel was 50% (95% CI: 44-57%), with I&#xb2; = 98.5 and 44% (95% CI: 30-60%), with I&#xb2; = 95.4, respectively. The subgroup differences test (p&#x2009;=&#x2009;0.54) for population type revealed no statistically significant difference. The Begg's test (p&#x2009;=&#x2009;0.2378) and Egger's test (p&#x2009;=&#x2009;0.8893) showed no significant evidence of bias. The significant variation between the two diagnostic methods (p&#x2009;=&#x2009;0.03) showed that the observed heterogeneity may be due to diagnostic methods used across the studies.<br><br>CONCLUSION: The high pooled prevalence of MRSA in Pakistan highlights an urgent need for strengthened antimicrobial stewardship, standardized surveillance systems, and integrated infection prevention strategies.}, }

Although traditional wisdom has considered immunosuppression risky when antimicrobial therapy is required, modern insights into immune biology reveal a more nuanced landscape in which targeted immunomodulators can attenuate harmful inflammation without broadly compromising host defence. This evolution is particularly relevant in paediatrics, influenced by developmental stage, distinct exposure history and patterns of host response. The COVID-19 pandemic catalysed wider acceptance of immunomodulation in infection management, including corticosteroids in children and highlighted safe use of agents such as baricitinib. Platform trials of the hyperinflammatory syndrome (paediatric inflammatory multisystem syndrome temporally associated with SARS-CoV-2) also identified benefits of methylprednisolone and tocilizumab in select groups. For other paediatric infections, including dengue, influenza and Epstein-Barr virus, the evidence remains sparse, with emerging mechanistic and early-phase clinical studies exploring interleukin (IL)-1 blockade, corticosteroids, immunoglobulin and anticytokine biologics. In paediatric sepsis, immunophenotype-guided trials represent a major conceptual advance. Adaptive studies, such as TRIPS and GRACE-2, aim to tailor immunomodulation to hyperinflammation or immunoparalysis, though definitive efficacy data are awaited. Parallel efforts in ARDS explore statins, IL-6 blockade and cell-based therapies, but robust paediatric evidence is still lacking. Collectively, evolving insights and trial designs offer renewed opportunities to use targeted immunomodulation in the management of paediatric infection. Large-scale, collaborative paediatric research networks will be essential to translate these advances and better integrate infection research into everyday paediatric practice.}, }

In this review, we aim to discuss the reasons underlying this increasing interest. First, we describe the different methods used to assess blood pressure variability, including very short-term (beat-to-beat), short-term (24-h ambulatory blood pressure monitoring), mid-term (home self-measurements), and long-term (visit-to-visit measurements), as well as the mathematical indices used to quantify it. We then address the clinical relevance of blood pressure variability. First, increased variability is more prevalent in several health conditions not necessarily related to vascular disease, such as mental illness, severity of COVID-19 infection, bone fractures, and various forms of cognitive impairment. Second, blood pressure variability appears to be involved in the progression from prehypertensive states to established hypertension and, once hypertension is present, in the development of target organ damage. It has also been associated with an increased risk of gestational hypertension, preeclampsia, and adverse neonatal outcomes. Furthermore, blood pressure variability, even independently of mean arterial blood pressure, influences the development, prognosis, and complications of coronary and cerebrovascular disease. Finally, we discuss evidence suggesting that blood pressure variability is associated with both vascular and all-cause mortality.}, }

Eligible articles were those reporting structured change management processes in the context of virtual care published between 1st January 2019-31st December 2023, identified by searching four electronic databases (Scopus, MedLine, PsycInfo and Business Source Premier). Data were extracted and synthesised from the eligible studies.<br><br>RESULTS: Seventeen studies met inclusion criteria describing changes occurring within hospital settings or in community health centres. Kotter's 8-Step Model was the most frequently applied change framework, often combined with other approaches. Commonly enablers included high quality communication among all parties involved and strong leadership. Common barriers included overemphasis on technology at the expense of people and processes, linear application of models, and lack of mechanisms to monitor change progress.<br><br>DISCUSSION: Structured change methodologies were often integrated in a strategic change framework with process improvement methods utilised to support the change process. Managing change relating to the technology with attention to the clinical and people aspects of change was considered a key gap and challenge in the context of virtual care change.

Cancer patients have significantly higher VTE risk than the general population, due to hypercoagulable states and anticancer therapies, with those with advanced malignancies carrying the highest risk. Primary thromboprophylaxis and anticoagulation are pivotal for CAT management. Despite advances, key challenges include different thrombotic and bleeding risks across cancers and how recurrent VTE affects anticoagulation duration. Low-molecular-weight heparin (LMWH) has largely replaced warfarin, and direct oral anticoagulants (DOACs) are challenging LMWH's first-line role with proven efficacy. However, the key dilemma is balancing thromboprophylaxis and treatment against anticoagulant-induced bleeding, particularly in the context of recurrent VTE. Current CAT guidelines show discrepancies and gaps in clinical coverage; some conclusions derived from meta-analyses need validation via more randomized controlled trials. This review synthesizes recent CAT research (focused on VTE) across epidemiology, pathophysiology, laboratory assessments, and management. It analyzes how cancer type, patient conditions, and drug-drug interactions influence anticoagulant selection, supported by a review of the corresponding experimental evidence. Additionally, the article addresses key clinical scenarios (e.g., intracerebral hemorrhage, pregnancy, pediatric and adolescent patients, and COVID-19) to aid clinical decision-making, delineates unresolved clinical controversies, and integrates high-quality cohort/subgroup data to guide meta-analysis validation. By summarizing risk-benefit consideration, this article provides a framework for complex cases and informs future RCT design.}, }

The COVID-19 pandemic has shown us how important it is to have health systems that can quickly find and track new viruses as they spread and has ushered in a new era of genomic surveillance, allowing scientists to track the evolution of the coronavirus, providing public health strategies. Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2), responsible for the COVID-19 pandemic, has been associated with very important global morbidity and mortality. The discovery of SARS-CoV-2 in bats and pangolins in South Asian countries indicates that SARS-CoV-2 likely originated from wildlife being the third highly pathogenic human coronavirus. The increased contagiousness of SARS-CoV-2 virus was due to the spike glycoprotein (S) that favors the attachment of the virus to the cell surface. SARS-CoV-2 infection triggers a damaging triad of oxidative stress, intense inflammation with cytokine storm, and endothelial dysfunction, leading to widespread cellular damage, blood clotting with thrombosis, and organ failure by overwhelming the body's antioxidant defenses, damaging blood vessel linings, and promoting hyperinflammation, all crucial factors in severe COVID disease. The purpose of the review is to make a synthesis of the data known so far about SARS-CoV-2 virus etiology, the complex interactions between the virus and the host, imbalanced immune response and cytokine storm, molecular mechanisms by which the spike protein drives endothelial dysfunction and, multisystemic pulmonary, cardiovascular, neurological, renal involvement.}, }

This review systematically outlines key advancements in organoid-based virology, including the propagation of hard-to-culture pathogens such as human rhinovirus C (HRV-C) and norovirus (NoV), as well as novel insights into viral pathogenesis, including the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and Zika virus (ZIKV) infection, and the translational utility of organoids for antiviral drug screening and preclinical assessment. It further examines the use of organoids in modeling cancer and neurological diseases, compares the strengths and limitations of different cellular sources, and discusses their potential integration with emerging technologies such as CRISPR gene editing and 3D bioprinting. In addition, it maps a translational pathway from molecular mechanisms to clinical practice to facilitate the study of disease mechanisms and accelerate drug and vaccine development. Finally, holistic strategies are proposed to address existing challenges, such as the lack of immune components and inadequate vascularization. Together, these efforts aim to promote the broader adoption of organoid technology across the life sciences and translational medicine.}, }

We conducted a systematic review and meta-analysis, following PRISMA guidelines and PROSPERO registration (CRD42023463720), to estimate PGD prevalence under standardized ICD-11 and DSM-5-TR diagnostic frameworks and to examine potential moderators during the COVID-19 pandemic. PubMed, EMBASE, and the Cochrane Library were searched from inception to October 2024. Eligible studies included adults who experienced bereavement during the pandemic and were assessed using validated PGD instruments (PG-13-R, ICG, BGQ). Random-effects models were applied to pool prevalence estimates, with subgroup and meta-regression analyses. Thirteen studies comprising 5,766 participants were included. The pooled prevalence of PGD during the pandemic period was 24% (95% CI: 13%-36%), with the highest estimates observed in China (43%, 95% CI: 33%-54%). In the overall pooled analysis, studies applying DSM-5-TR criteria yielded lower prevalence estimates than those using ICD-11 criteria (18% vs.26%, p = 0.41). Digital interventions showed no statistically significant pooled effects (Hedges' g = -0.38, 95% CI: -0.90 to 0.14).

Methods A scoping review was conducted using Arksey and O'Malley and Levac frameworks, guided by the PRISMA-ScR checklist. The protocol was registered on the Open Science Framework. Systematic searches were carried out in PubMed, EMBASE, and Scopus for studies published in English between January 2010 and December 2024. Eligible studies included empirical research on barriers to help-seeking among individuals with cancer in India. Titles and abstracts were screened using Rayyan, followed by full-text review. Data were charted and synthesised thematically. Results Of 349 records screened, 30 studies met the inclusion criteria. Barriers were categorised as: financial and economic, lack of awareness/knowledge, cultural stigma and embarrassment, reliance on alternative medicine, systemic and health system inefficiencies, psychological fear and distrust, family and gender bias, and COVID-19-related disruptions. These factors collectively led to delays in presentation, diagnosis, and treatment of cancer in India. Interpretation and conclusions Delays in cancer care in India arise from intersecting socio-economic, cultural, systemic, and gendered barriers. Strengthening insurance coverage, patient navigation, awareness initiatives, gender-sensitive services, and long-term investments in rural infrastructure and psychosocial support are critical to improving timely cancer care.}, }

Available evidence suggests that myocarditis following COVID-19 vaccination remains uncommon at the population level, predominantly affecting younger males and more commonly reported after mRNA-based vaccines. Most reported cases appear to follow a benign and self-limited clinical course. These findings support the overall favorable benefit-risk profile of COVID-19 vaccines while underscoring the need for continued pharmacovigilance and more robust epidemiological studies to better characterize the epidemiology of vaccine-associated myocarditis.}, }

The continuous emergence of variants with enhanced immune evasion capabilities, coupled with the prolonged and debilitating symptoms of Long Coronavirus Disease (Long COVID) such as intermittent dyspnea, persistent fatigue, and cognitive impairment (brain fog), has become a major global concern. The pathogenesis of COVID-19 is a complex interplay of direct viral cytotoxicity and an overwhelming secondary inflammatory response in the host, with the latter being a key driver of immune homeostasis disruption. Accumulating evidence indicates that PANoptosis, an integrated programmed cell death process involving the crosstalk and coordinated activation of apoptosis, pyroptosis, and necroptosis, is closely linked to the cytokine storm syndrome triggered by SARS-CoV-2 infection. As a critical mediator of various infectious diseases, PANoptosis plays a pivotal role in regulating the balance between viral clearance and pathological inflammation. This review specifically targets SARS-CoV-2, adopting a "basic mechanism-molecular regulation-therapeutic target-clinical translation" framework. We elaborate on SARS-CoV-2-induced PANoptosis mechanisms, including its constituent cell death pathways and contributions to cytokine storms. By dissecting the intricate regulatory networks between PANoptosis and interferon (IFN) signaling during viral infection, this work aims to identify potential therapeutic targets and provide novel insights for the development of effective strategies to mitigate severe COVID-19 and its long-term sequelae.}, }

Although the precise cause of MS is unknown, previous studies have found a strong link between MS and certain viral infections, leading researchers to speculate that viruses may play a role in MS pathogenesis by acting as environmental triggers. We present a comprehensive review of viral associations with MS, focusing on viruses with strong evidence for involvement in disease development, including members of the Herpesviridae family-such as Epstein-Barr virus, human herpesvirus 6, varicella-zoster virus, herpes simplex virus 1, cytomegalovirus, and SARS-CoV-2. Those viruses appear to modulate the neuro-immunological system in genetically susceptible individuals, leading to immune-mediated demyelination. Viral exposure is thought to represent an early initiating or permissive event that triggers downstream immune dysregulation, ultimately leading to MS onset in predisposed hosts. Additionally, they can cause latent infections with episodes of reactivation, which might be associated with relapsing presentation of MS. Several theories have been proposed to explain the viral etiology of MS, including molecular mimicry, virus-induced inflammatory response, autoreactive T- and B-cell activation, and increased susceptibility to antigenic exposure. Besides addressing the current knowledge gap, we also highlight future research directions for effective MS management, including developing experimental models and conducting clinical trials, identifying specific biomarkers, and investigating novel antiviral agents. An improved understanding of MS etiology and the role of viruses in its physiopathology may enable more targeted interventions and better treatment outcomes.}, }

These properties impose variation-independent constraints that may serve as potential targets for sequence-agnostic antiviral modulation. Here, a mechanistic hypothesis is proposed in which, under physiologically humid respiratory system conditions, inhalation of low-concentration ethanol vapor may generate a transient, ethanol-enriched microenvironment at airway surface liquid (ASL) and alveolar lining fluid (ALF) interfaces. Rapid vapor-liquid partitioning is hypothesized to permit short-lived interactions between ethanol molecules and viral lipid envelopes during airborne transit or early epithelial contact. Such interactions may transiently increase envelope rigidity, reduce membrane fluidity, constrain spike conformational dynamics, and raise the energetic barrier for membrane fusion, thereby biasing early entry processes against successful infection. This mechanistic framework is grounded in established principles of membrane biophysics, amphiphile-lipid interactions, and diffusion kinetics. It focuses on localized physicochemical modulation at gas-liquid interfaces and does not invoke systemic ethanol exposure, therapeutic dosing, or clinical intervention. In addition, delayed viral entry kinetics arising from altered envelope mechanics may, in principle, modulate the timing of host immune activation, potentially attenuating excessive inflammatory responses. By targeting conserved envelope mechanics rather than sequence-specific viral components, this hypothesis introduces physical microenvironmental modulation as a complementary conceptual domain in antiviral research and provides a foundation for future experimental and computational evaluation of enveloped virus entry dynamics.}, }

However, they present pharmacological limitations, a mixed efficacy profile and target just two coronavirus proteins. To extend the range of druggable coronavirus proteins, researchers explored small molecule N-glycan binders as inhibitors of SARS-CoV-2 spike protein interaction with the cell receptor. Other groups investigated lipopeptides as inhibitors of cell fusion by viral spikes. High throughput screening of chemical libraries yielded viral maturation inhibitors that targeted the viral M protein. Massive screening led to inhibitors of the non-structural coronavirus protein NSP14, a methyltransferase involved in viral mRNA cap synthesis. Machine learning-driven scans of chemical space revealed inhibitors of non-structural coronavirus protein NSP3, a papain-like protease subverting innate immune response to viral infection. A chimera of a nucleotide analogue coupled to an RNase L attractor bound the RNA-dependent RNA polymerase NSP12 and mediated degradation of the viral RNA. Several of these compounds showed comparable or even superior antiviral efficacy as approved COVID-19 drugs in preclinical animal tests. Parallel efforts were made to develop chemical compounds targeting host proteins needed for viral multiplication. Peptidomimetic tetrapeptides acted as inhibitors of the host protease TMPRSS2 involved in cell fusion by the viral spike protein. A repurposed TMPRSS2 inhibitor was tested in COVID-19 patients without demonstrating efficacy. A genetic screen demonstrated an enzyme involved in sphingomyelin synthesis and its inhibitor which impaired SARS-CoV-2 replication. A viral-cell protein interactome study showed 332 cellular proteins interacting with 26 coronaviral proteins. A chemoinformatic search found inhibitors for the interaction of NSP9 with host elongation factor eIF4A and for NSP13 with elongation factor eEF1A.

This review was prospectively registered with PROSPERO (CRD42024503853) and included searches of PubMed, Embase, Global Health, the Cochrane Library, Africa Index Medicus, LILACS, and SciELO. We extracted data on bacteriologically confirmed and smear-positive TB prevalence among adults (aged&#x2009;&#x2265;&#x2009;15 years), stratified by sex. Risk of bias was evaluated using eight criteria specific to prevalence surveys. We fit multi-level Bayesian regression models with study- and country-level random effects to estimate the M:F ratio of TB prevalence (male prevalence divided by female prevalence), overall and for key subgroups. In meta-regression analyses, we estimated how prevalence ratios varied over time and according to known TB risk factors and TB case definitions. We identified 10,124 publications and extracted data from 100 eligible studies representing 102 unique prevalence surveys and 4,658,310 participants (45.6% male) in 33 LMICs. TB prevalence was higher in men than women in 90/102 of the included surveys, with a pooled M:F prevalence ratio of 2.02 (95% credible interval (CrI): 1.71, 2.34) for bacteriologically confirmed TB and 2.38 (95% CrI: 1.91, 2.90) for smear-positive TB. Time trend analyses showed a 2.0% (95% CrI: -0.2, 4.5%) average annual change in the M:F ratio of bacteriologically confirmed TB over the study period. The M:F prevalence ratio was estimated to be higher for countries with greater excess HIV prevalence among men, and countries with greater gender equity (as measured by the United Nation's Gender Development Index). The estimated M:F prevalence ratio was also higher for surveys that did not restrict testing to individuals reporting TB symptoms.

Among the constructs most relevant to this domain are moral distress, work engagement, and meaningful work. This narrative review aimed to synthesize conceptual and empirical evidence on these three constructs and to examine their interrelations and implications for healthcare practice. A selective narrative review of the literature was conducted, integrating theoretical frameworks, systematic and integrative reviews, and empirical studies, resulting in a final synthesis of 41 articles. Moral distress arises when clinicians are prevented from acting in accordance with their ethical convictions, often due to institutional or systemic constraints, and has been consistently associated with burnout, turnover, and compromised quality of care. In contrast, work engagement - characterized by vigor, dedication, and absorption - and meaningful work - reflecting the perception that professional activities have meaning and purpose - function as protective factors that enhance resilience and sustain intrinsic motivation. Evidence highlights the central role of organizational climate, leadership, resource availability, and ethical culture in shaping experiences of distress, engagement, and meaningfulness, a dynamic further intensified during the COVID-19 pandemic. The synthesis emphasizes that organizational and systemic interventions, including ethics consultation, supportive leadership, workflow redesign, and resilience-building programs, are essential to mitigate moral distress and promote engagement and meaningful work. The integration of these constructs aligns with the Quadruple Aim, reinforcing the premise that caring for healthcare professionals is indispensable to caring for patients.}, }

In this review, we summarize the major circuits by which MNPs may transport into and out of the CNS, including blood-brain barrier crossing, nasal-to-brain routes, and glymphatic system transport. Small-sized MNPs are difficult to eliminate from the brain, which may explain why MNPs may accumulate in the brain. We further discuss the potential neurotoxic effects of MNPs, such as inducing synaptic and neuronal injury, promoting neuroinflammation, dysregulating the neuroendocrine system, and modulating the gut-brain axis. MNP-induced CNS toxicity follows a pattern in which increased susceptibility occurs before direct toxicity. We also review evidence that MNPs, together with environmental and genetic factors, may synergistically contribute to cognitive impairment in Alzheimer's disease, motor dysfunction in Parkinson's disease, and depression- and anxiety-like behaviors. Prenatal exposure to MNPs might induce autism spectrum disorder-related phenotypes in offspring. MNPs could also obstruct cerebral vessels and trigger acute cerebrovascular diseases, as well as promote the entry of viruses such as SARS-CoV-2 into the CNS, thereby increasing the occurrence of neurological symptoms. Finally, this review discusses physical, pharmacological, and plastics substitution interventions designed to regulate MNPs transport in the brain and enhance neuroprotection, thereby reducing CNS toxicity of MNPs.}, }

Multi-omics datasets, including genomics, transcriptomics, epigenomics, proteomics and metabolomics provide a complete view of virus-host interactions. However, the integration and interpretation of these high dimensional datasets remain a major challenge. To overcome this, artificial Intelligence (AI), including machine learning (ML) and network-based approaches, has proven to be a powerful tool to analyze, integrate, and interpret multi-omics data. This chapter discusses examples from studies on SARS-CoV-2, HIV, influenza, EBV and others, where AI has been applied to multi-omics research. These studies show how AI-assisted multi-omics approaches are helping in the advancement of viral disease research by providing better understanding of virus induced cellular changes, identifying biomarkers, designing targeted therapies etc. Therefore, integrating multi-omics with AI enables improved diagnosis, treatment, and prevention of viral diseases. We have also discussed challenges faced in combining multi-omics with AI and highlighted future directions that would help in enhancing AI assisted multi-omics research.}, }

The lack of effective therapies for LC is straining healthcare systems worldwide and causing widespread public health and socioeconomic concerns. "Fibromyalgia" is a controversial chronic pain condition of unknown etiology largely attributed to generalized sensory hypersensitivity due to dysregulated central pain processing pathways (i.e. neuroplasting central sensitization). Despite intense research and growing attention in the scientific community, the clinical overlap of fibromyalgia, somatic symptom disorder, and post-viral chronic fatigue, is a medical puzzle yet to be solved, especially when occurring in non-severe infections and previously healthy individuals.<br><br>METHODS: This systematic scoping review covers the empirical findings on new-onset fibromyalgia manifestations after non-hospitalized covid-19. MEDLINE, Web of Science, and APA PsycINFO were searched in a systematic scoping approach for empirical studies on new-onset fibromyalgia after non-severe non-hospitalized covid-19, charting study characteristics and outcome data. A total of 228 records were included.<br><br>FINDINGS: Various types of methods, tools, and study designs are being used for LC research, with inconsistency in key concepts and definitions. This leads to a fragmented understanding of the relationship between SARS-CoV-2 infection and LC. Prevalence studies of post-Covid fibromyalgia are ongoing and susceptible to bias. The empirical evidence supports an overlap between LC, chronic fatigue syndrome, and fibromyalgia but the molecular mechanisms still remain unclear. There are conflicting findings regarding presence of viral particles, central sensitization, autoantibodies, and more.<br><br>DISCUSSION: This review highlights the need for standardized definitions and rigorous methodologies in research on LC. Future research should focus on epidemiological population-based studies with representative sampling and improving methodology, refining evolving definitions, harmonization of research, elucidating neurological mechanisms in hypothesis driven studies, and developing effective therapeutic strategies. The discussion synthesizes findings and offers an integrative mechanism for the pathophysiology of fibromyalgia and multisystem medically unexplained manifestations of LC as a non-autoimmune connective tissue disease. It helps explain neuropsychiatric and psychosomatic manifestations and is used to make testable theory-based predictions for future hypothesis-driven investigations.}, }

While biosafety concerns have restricted postmortem examinations in such contexts, the COVID-19 pandemic has renewed interest in autopsy-based research and highlighted both the potential and the gaps in current biosafety protocols. This narrative review outlines autopsy practices in the context of high-consequence infectious diseases (HCIDs) with a focus on VHFs, summarizes reported autopsy cases, explores alternative postmortem methods and examines the evolution of legal and institutional frameworks in response to the pandemic. A comparison of official international guidelines shows that while detailed autopsy protocols have been published for pathogens requiring BSL-3 containment - particularly in the United States (US) and United Kingdom (UK) - no official procedural guidance seem to be available for performing autopsies under BSL-4 conditions. Instead, current recommendations at this level are limited to postmortem handling and disposal of the deceased. This regulatory and procedural gap underscores the urgent need for harmonized, high-containment autopsy protocols that balance biosafety with scientific value. Developing such frameworks will be essential to improve outbreak preparedness and enabling evidence-based responses to future pandemics globally. Accordingly, we propose a structured, system-based approach to BSL-4 autopsy practice as a foundation for discussion and future guideline development.}, }

Conventional viral detection techniques, although highly specific, often suffer from slow, labour-intensive workflows that limit their applicability for rapid diagnosis. Moreover, their reliability can be compromised by factors such as inadequate technical expertise and improper sample handling, potentially leading to erroneous results. When the global public health system is continuously struggling to control viral diseases like dengue, influenza, hepatitis B, and acquired immunodeficiency syndrome, cutting-edge nanotechnology and biosensor-enabled next-generation diagnostic platforms have shown improved analytical performances. Among these, aptamer-conjugated nanoparticles (ACNPs) have emerged as a promising nanosystem that integrates the high molecular recognition capability of aptamers with the unique physicochemical and optical properties of nanoparticles. Aptamers are short, single-stranded DNA, RNA, or peptide sequences that offer remarkable affinity and selectivity toward diverse viral biomarkers, including proteins, nucleic acids, and intact virions. Their conjugation with nanoparticles imparts superior stability, signal amplification, and biofunctional versatility under physiological conditions. These hybrid systems demonstrate substantial potential in biosensing, bioimaging, and providing enhanced diagnostic precision. This review aims to present the fundamental design principles of ACNP-based detection strategies and to highlight recent advances in viral diagnostics. Additionally, it underscores the underlying sensing mechanisms and analytical advantages, and discusses the current challenges associated with ACNP-enabled diagnostic platforms.}, }

Innovation is often born out of necessity, and during the Coronavirus disease 2019 (COVID-19) pandemic, there was a surge of telemedicine initiatives both in surgical education and surgical care delivery. This has been well documented in high-income countries, but there has been less evaluation of the use and potential application of telemedicine in low- and middle-income countries (LMICs) to support surgical outreach efforts.

A total of 4783 records were initially identified, of which 45 studies met the inclusion criteria, encompassing 468,769 dairy cattle across 10 countries.<br><br>RESULTS: The global pooled bTB prevalence was 6.9% (95% CI: 4.4-9.9). Africa had the highest regional prevalence (12.4%, 95% CI: 6.6-19.7), and Ethiopia the highest among countries (16.6%, 95% CI: 7.8-27.9). Low-income countries showed higher prevalence (16.7%, 95% CI: 8.9-26.3) than others. Rapid antibody tests yielded significantly higher infection rates (24.8%, 95% CI: 9.7-44.1) than other diagnostic methods. Prevalence differed significantly between lactating and non-lactating cows (p&#x202f;<&#x202f;0.05). Other risk factors assessed included breed, sex, age, farming mode, sampling time, sample type, and tuberculin type.<br><br>CONCLUSIONS: bTB remains a significant challenge in dairy production, demanding tailored control strategies adapted to regional contexts. However, the geographic distribution of available studies was heavily skewed, with the majority originating from China and Africa, while regions with advanced control programs were underrepresented. This geographic limitation should be carefully considered when interpreting the global estimates. Surveillance efforts should prioritize high-risk populations, particularly hybrid cattle, aging animals, and lactating cows, through the combined use of interferon&#x2011;&#x3b3; release assays and tuberculin tests.

Increasing evidence indicates that viral infections can alter host miRNA expression profiles, influencing viral replication, immune responses, and disease severity. In this review, we summarize current knowledge on miRNA dysregulation in major pandemic-prone viral infections, including severe acute respiratory syndrome coronavirus (SARS-CoV), SARS-CoV-2, (middle east respiratory syndrome coronavirus) MERS-CoV, and influenza viruses. We also discuss how specific miRNAs may function as antiviral or proviral regulators by targeting viral genomes or key host signaling pathways involved in immune responses and inflammation. Particular attention is given to the potential role of circulating miRNAs as diagnostic or prognostic biomarkers, as well as the emerging concept of miRNA-based therapeutics. While numerous studies report associations between altered miRNA expression and infection outcomes, most findings are derived from relatively small and heterogeneous cohorts and require further validation. Consequently, many proposed miRNA applications remain at an exploratory stage. Nevertheless, advances in high-throughput sequencing, integrative omics approaches, and functional validation studies are expected to improve our understanding of miRNA-mediated regulatory networks during viral infections. These developments may ultimately support the development of host-response biomarkers and therapeutic strategies that contribute to improved surveillance and preparedness for future viral outbreaks.}, }

Despite their importance, quarantine and vaccination alone are insufficient, necessitating advanced approaches for effective viral infection control. One such strategy involves investigating efficacious antiviral agents that don't induce toxicity. Algal polysaccharides represent a significant frontier in pharmacological research for the development of novel antiviral therapeutics. Unlike other sources, marine algae offer an underexploited reservoir of unique metabolites with potent, broad-spectrum antiviral properties. A multitude of studies have recognized numerous algal polysaccharides exhibiting antiviral characteristics, including laminaran, alginate, carrageenan, fucan, and naviculan. Moreover, these polysaccharides exert antiviral effects through diverse mechanisms, including blocking viral attachment and entry into host cells, as well as inhibiting viral genome replication and protein synthesis. The shift towards treatment with polysaccharides derived from marine algae represents a step towards more flexible and resistance-resistant antiviral strategies. By leveraging the gradual evolution of algal metabolites, researchers can develop agents that are not only effective against current threats but also adaptable to changes in the antigenic composition of future viral outbreaks. This review summarizes recent advances in the current understanding of algal polysaccharides, including their production, extraction methods, structural characterization, and applications in gene delivery. It also provides a critical discussion of structure-activity relationships, antiviral mechanisms, and comparative evaluation of different classes of algal polysaccharides to support their advancement as promising natural antiviral agents for future research and therapeutic development.}, }

Because lung injury is driven by uncontrolled inflammation and disruption of the alveolar–capillary barrier, corticosteroids have long been considered a biologically plausible therapy. Over several decades, randomized trials have evaluated different corticosteroid types, doses, durations, and initiation timings in heterogeneous populations, including patients with primary ARDS and those with sepsis or pneumonia complicated by ARDS. The COVID‑19 pandemic provided a unique opportunity to study a more homogeneous cause of ARDS, generating additional evidence supporting corticosteroid efficacy in virus‑related respiratory failure. Despite these advances, clinical practice remains variable worldwide. Evolving definitions, diverse trial designs, and etiologic variability have led to uncertainty regarding indication, optimal dosing, drug selection, and treatment duration. The new global definition of ARDS now includes patients supported with noninvasive ventilation or high‑flow nasal oxygen, raising questions about how evidence derived from invasively ventilated populations applies to these groups. Parallel research identifying inflammatory subphenotypes with potentially divergent treatment responses further underscores the need for individualized, evidence‑based strategies. In this review, we examine conceptual, biological, and clinical considerations and synthesize the available evidence to inform decision‑making. We propose a pragmatic, context‑based framework to guide corticosteroid use in ARDS according to etiology and patient characteristics, emphasizing early initiation—ideally within 24–48 hours—and regimens equivalent to ≥80 mg/day of methylprednisolone or ≥400 mg/day of hydrocortisone for at least seven days, which have demonstrated efficacy with an acceptable safety profile.

Since the COVID-19 pandemic, interest in both static and dynamic modelling has expanded. Therefore, this review aimed to summarize current evidence on the use of longitudinal blood biomarker data in ICU prediction models, assess how the pandemic shaped this research, and report validation strategies.<br><br>METHODS: This scoping review followed the PRISMA-ScR guidelines. PubMed and Google Scholar were searched for studies on blood biomarker trajectory analysis in the ICU published between 2014 and 2025, covering five years before and after the onset of the COVID-19 pandemic.<br><br>RESULTS: Forty-seven studies were included, mainly from North America (47%), Europe (45%), and Asia (34%). ICU and hospital mortality were the predominant outcomes. Although 53% of studies used pre-pandemic data, 94% were published afterwards. The most frequent biomarker categories were immune response (74.5%) and metabolic/organ function (66.0%). Common biomarkers included platelets and lactate (n&#x2009;=&#x2009;9), lymphocytes and mHLA-DR (n&#x2009;=&#x2009;6), and creatinine and interleukin-6 (n&#x2009;=&#x2009;5). Modelling approaches integrated longitudinal regression-based models (31.9%), latent class-based models (44.7%), and machine-learning/data-driven clustering (27.7%). Trajectory patterns varied depending on both biomarker type and modelling technique. Cox regression, Kaplan-Meier, and logistic regression were commonly applied to assess associations with outcomes. Notably, only 21% of studies reported any form of validation, highlighting a major limitation for clinical applicability.<br><br>CONCLUSION: Blood biomarker trajectories have potential to improve dynamic risk prediction and stratification, supporting targeted prevention through early identification of high-risk patterns, and enable more personalized treatment via adaptive, patient-specific approaches. Nevertheless, substantial methodological heterogeneity and the low proportion of validated models limit clinical applicability. Greater standardization and robust validation are essential to facilitate translation into PPPM-oriented intensive care.<br><br>SUPPLEMENTARY INFORMATION: The online version contains supplementary material available at 10.1007/s13167-026-00456-5.}, }

In the post-coronavirus disease (COVID)-19 era, there has been a marked expansion in WALANT-related literature, necessitating synthesis of contemporary evidence to guide clinical practice. This narrative review examines recent WALANT studies organized into six thematic domains: comparative trials versus traditional anesthesia, use in the pediatric population, patient satisfaction and experience, environmental impact, cost comparison and value-based care, and applications beyond the hand and wrist. Comparative studies consistently demonstrate that WALANT provides noninferior functional outcomes and complication rates relative to regional and general anesthesia, with improved intraoperative pain and similar early postoperative pain. Pediatric data support feasibility and high satisfaction in appropriately selected patients, particularly adolescents. Patient satisfaction is uniformly high, with strong willingness to repeat WALANT procedures. WALANT pathways also reduce solid waste and carbon emissions, particularly when procedures are performed outside the main operating room. Cost analyses demonstrate substantial savings driven by decreased anesthesia use and site-of-service optimization. Expanding indications now include proximal upper extremity procedures and select nonupper extremity surgeries, reflecting increasing surgeon experience and confidence. WALANT represents a mature, evidence-supported care pathway that aligns clinical outcomes with patient-centered experience, environmental sustainability, and cost efficiency. Its greatest impact is realized when integrated into procedure room-based workflows with careful patient selection and standardized technique. Future efforts should focus on refining indications, optimizing patient experience, and expanding scalable implementation across diverse practice settings.}, }

The COVID-19 pandemic served as an unprecedented real-world stress test for these technologies, highlighting their potential to accelerate antigen design, guide antibody optimization, and anticipate viral evolution in near real time. AI driven approaches contributed to faster characterization of viral variants, supported vaccine and broadly neutralizing antibodies developments. Despite the significant contributions, the pandemic also revealed important limitations that must be addressed before such approaches can be relied upon as cornerstones of global preparedness. Challenges related to data bias, model interpretability, experimental validation bottlenecks, and integration with existing regulatory frameworks became increasingly apparent. In several cases, the gap between computational promise and translational readiness underscored the need for closer coupling between in silico design, laboratory experimentation, and clinical evaluation. Moreover, the rapid pace of AI innovation often outstripped established regulatory pathways, raising questions about standardization, validation, and long-term safety. This mini review provides a focused overview of recent advances in AI enabled computational protein design, with an emphasis on applications relevant to pandemic response. Drawing on lessons from COVID-19 case studies, it examines translational and regulatory considerations, highlights unresolved controversies, and identifies critical research gaps. Collectively, these insights outline a path toward transitioning AI designed vaccines and antibody therapeutics from reactive emergency tools into proactive, scalable infrastructures for future pandemic preparedness.}, }

Reactive oxygen species (ROS), traditionally associated with molecular damage, are now understood to directly regulate cytoskeletal remodeling, membrane viscoelasticity, mitochondrial dynamics, and mechanotransduction pathways including focal adhesion kinase (FAK), integrins, and Yes-associated protein/transcriptional coactivator with PDZ-binding motif (YAP/TAZ). Conversely, biomechanical forces such as extracellular matrix stiffness, cyclic stretch, and disturbed shear stress modulate intracellular redox signaling through mitochondrial dysfunction, NADPH oxidase activation, and inflammatory pathways. This bidirectional interaction forms a self-amplifying "redox-mechanobiological axis" that contributes to endothelial dysfunction, fibrosis, thrombosis, tumor progression, and viral pathophysiology.Trace elements, particularly selenium, zinc, and iron, emerge as critical modulators of this axis by influencing antioxidant defense systems, cytoskeletal integrity, membrane stability, ferroptosis, and cellular stiffness. Selenium-dependent selenoproteins regulate mitochondrial redox balance and actin organization; zinc stabilizes membrane architecture and mechanosensitive proteins; and iron-mediated Fenton chemistry promotes oxidative injury, ferroptosis, and biomechanical alterations.This review integrates molecular mechanisms, mechanobiological principles, and recent clinical findings-particularly from cardiovascular disease, cancer biology, and COVID-19-to propose a unified framework linking oxidative stress to biomechanical dysfunction. In addition, current controversies, methodological limitations, and future therapeutic directions targeting the redox-mechanobiological axis are critically discussed.}, }

Despite the popularity of traditional statistical approaches, the high dimensionality of transcriptomic data presents challenges for these conventional methods. While artificial intelligence (AI) algorithms have emerged as highly advantageous for handling these complex datasets, there is a lack of evaluation of these approaches in COVID-19 transcriptomic studies. This review aims to provide an evaluation of these studies employed for transcriptomic biomarker discovery in COVID-19 using AI, assessing their study designs, methodologies, and outcomes. Based on a comprehensive search for literature across five databases including Web of Science Core Collection, Scopus, PubMed/MEDLINE, IEEE Xplore Digital Library, and LitCovid from December 2019 to March 2025, this review selected 63 studies for a narrative synthesis of four key sections: (i) The Landscape of AI-Driven COVID-19 Transcriptomics, (ii) Limitations of Studies, (iii) A Proposed AI-Driven Transcriptomics Framework, and (iv) Clinical Translation Challenges, Opportunities, and Future Directions. Our analysis revealed limitations in data quality, sample size, and heterogeneity, as well as methodologies regarding validation and interpretability. Thus, we proposed an evidence-informed workflow that addresses these current limitations in study design, while acknowledging real-world constraints. We further discuss the emerging potential of agentic AI systems as a promising solution to current limitations. By bridging methodological gaps with translation considerations, this review can enhance pandemic response strategies for future emerging infectious diseases. Key Points Applications observed in reviewed studies mainly included applications in diagnosis and severity stratification of COVID-19 patients. The limitations of current studies included small sample sizes, the reliance on public datasets lacking detailed metadata, batch effects and data heterogeneity reducing model robustness, the lack of external validation, risks of data leakage and circular validation leading to inflated performance metrics, and challenges in model interpretability. An evidence-informed AI-driven framework is proposed, acknowledging real-world constraints including small pandemic cohort sizes, domain shift from viral evolution, and resource-limited settings, with emerging agentic AI systems offering potential solutions.}, }

We propose standardized modules for resistance passaging, sequencing and host-side-effect profiling so that monotherapies are assessed not only for antiviral potency but also for durability and host-cell perturbation. For combinations, we discuss Bliss, ZIP, HSA and Loewe models as complementary tools for identifying additive or synergistic regimens while accounting for toxicity, resistance suppression and drug-drug interactions. Finally, we outline how harmonized metrics can support organoid, animal and clinical prioritization, improve machine-learning datasets and guide pandemic response, including rapid monotherapy testing for some DNA viruses and early combination testing for RNA and reverse-transcribing viruses.}, }

We conducted a critical narrative synthesis of post-PHEIC recovery and the transformation of immunization systems in the region from 2023 to 2025.<br><br>METHODS: We thematically analyzed publicly available data from the WHO and other sources using a systems-oriented framework covering immunization coverage, equity, vaccine introductions, disease control, governance, financing, and data systems.<br><br>RESULTS: Regional coverage for most antigens was restored to 2019 pre-pandemic levels by 2024, e.g., three doses of diphtheria-tetanus-pertussis-containing vaccines at 76%. However, progress remains insufficient to meet the Immunization Agenda 2030 (IA2030) target of 90% coverage. In addition, there were 6.7 million zero-dose children in the 2024 birth cohort (6.3% higher than the 6.3 million in 2019), concentrated in a few countries. The IA2030 target is a 50% reduction in the number of zero-dose children by 2030, compared to 2019. Recovery initiatives have restored services, while accelerated introductions (e.g., malaria vaccines introduced in 20 new countries in 2024-2025) signal renewed system momentum. Yet, progress has plateaued at pre-pandemic levels, reflecting structural constraints rather than sustained transformation. Concurrently, recurrent outbreaks of measles, yellow fever, and other vaccine-preventable diseases highlight persistent immunity gaps and surveillance limitations. Structural constraints (including financing fragility, subnational inequities, and system fragmentation) continue to limit sustained progress.<br><br>CONCLUSION: This study offers important insights that can inform immunization policymaking in the WHO African Region and beyond. Current post-PHEIC trends reflect recovery without transformation. Achieving IA2030 targets will require a shift from broad coverage expansion to precision delivery approaches that prioritize zero-dose and underserved populations. Immunization must be positioned as a central pillar of primary health care and health security systems.}, }

Neutralization assays, including live-virus, pseudovirus (PsV), and surrogate assays, offer functional insights into the ability of antibodies to prevent viral entry, though they often require higher biosafety levels and optimization. Serological assays, primarily antibody binding assays and several surrogate neutralization assays, received Emergency Use Authorization (EUA) during the pandemic, supporting seroprevalence efforts. Antibody binding assays and neutralization assays were also widely used in vaccine immunogenicity studies. Despite many standardization initiatives, assay standardization and data harmonization remain challenging and require further efforts. The choice of assay should be guided by study goals: antibody binding assays are preferred for high-throughput monitoring and epidemiological studies, while neutralization assays are essential for assessing functional immunity and variant-specific neutralization and protection.}, }

Objective: We conducted a scoping review to map and synthesize available evidence on how the COVID-19 pandemic has affected human papillomavirus (HPV) vaccination programs in low- and middle-income countries (LMICs) focusing on changes in vaccine delivery and coverage, determinants of uptake, economic and programmatic consequences and vaccine hesitancy. Methods: Inclusion criteria were limited to studies published in the English language between January 2020 to May 2025, and followed JBI and Arksey &amp; O'Malley's scoping review guidelines. The review proceeded through three stages: database searches, gray literature and citation tracking and used a PRISMA-ScR checklist to guide narrative and tabular synthesis. Results: A total of 1063 records, 57 studies were included in the final analysis, and these were spread out across 37 low- and middle-income countries (LMICs) mainly in Africa, Asia, and Latin America. Our analysis revealed that HPV vaccination coverage declined substantially during the COVID-19 pandemic, with reductions of up to 90% reported across the included studies, in the context of school closures, workforce redeployment, and supply-chain disruptions. Recovery efforts also faced major barriers including vaccine hesitancy, misinformation about COVID-19 vaccines, and travel restrictions. Strategies like digital tools, mobile clinics, and community health workers showed promise alongside integrated school- and facility-based approaches, although there is limited evidence on cost-effectiveness and long-term sustainability of these strategies. Conclusions: HPV vaccination in LMICs was significantly disrupted by the COVID-19 pandemic due to unreliable vaccine supply chains, health-worker shortages, and challenges tied to school-based vaccine delivery. Although recovery methods show potential, longer observation periods are needed to determine their full effectiveness.}, }

Despite widespread feline coronavirus infection, only a subset of infected cats progresses to feline infectious peritonitis, indicating that host immune responses are key determinants of disease outcomes. Accumulating evidence indicates that disease severity is driven not only by viral replication but also by macrophage- and monocyte-centered immune signaling, leading to excessive inflammation and systemic immunopathology in the host. Previous vaccine approaches against FIPV have failed to provide consistent protection and, in some cases, have been associated with enhanced disease. These outcomes suggest that vaccine-induced immune responses that recapitulate pathogenic signaling patterns may exacerbate disease rather than confer protection. In this review, we discuss the current knowledge of immune cell signaling pathways implicated in FIPV infection, including innate sensing through Toll-like receptors, downstream mitogen-activated protein kinases and NF-κB signaling, cytokine production profiles, Fc receptor-associated processes, and intracellular pathways such as autophagy, and how these mechanisms shape vaccine-induced immunity. By integrating insights from immune signaling kinetics, antibody functionality, adjuvant-driven pathway engagement, and platform-specific immune signatures, this review emphasizes the need to reframe FIPV vaccine development strategies that actively shape host immune responses. Rather than maximizing immunogenicity, successful vaccine design is likely to depend on limiting sustained macrophage activation and pro-inflammatory cytokine amplification while supporting antiviral immune functions, thereby reducing the risk of antibody-dependent enhancement and immunopathology. Beyond feline diseases, these considerations provide broader lessons for vaccine design in settings where immune-mediated pathology contributes to disease severity.}, }

Although conventional vaccines effectively prevent infectious diseases, their long-term efficacy is often limited by antigenic variation and reliance on a restricted number of licensed adjuvants. BMVs, as self-adjuvanting systems, enable both antigen delivery and innate immune activation. BMVs are nanoscale lipid bilayer structures enriched with pathogen-associated molecular patterns (PAMPs), facilitating their recognition and uptake by antigen-presenting cells. This leads to the activation of pattern recognition receptors and the induction of pro-inflammatory cytokines, type I interferons, and adaptive immune responses, including antibody production and Th1- and Th17-biased cellular immunity. Recent studies highlight the versatility of BMVs as vaccine platforms across bacterial, fungal, and viral infection models. BMVs induce protective immunity by promoting both systemic and mucosal immune responses, thereby reducing bacterial burden and limiting pathogen colonization across diverse infection models. These properties have supported their application in viral vaccine development, including influenza and SARS-CoV-2, with the potential to enhance mucosal immunity. Despite these advantages, challenges remain in standardization, safety, and antigen-loading efficiency. Engineered BMVs incorporating protein or mRNA antigens may further enhance antigen presentation and CD8[+] T cell responses.

Body composition techniques provide more detailed insights into tissue distribution but are constrained by cost and infrastructure requirements. Biochemical indicators offer high sensitivity for detecting metabolic and micronutrient alterations, yet their use in large-scale surveys is restricted by logistical and ethical challenges. The COVID-19 pandemic exposed vulnerabilities in data collection systems and highlighted the need for more resilient surveillance approaches. In parallel, digital technologies have expanded possibilities for data integration and analysis, although their implementation remains uneven across settings. A comprehensive approach to nutritional assessment requires the integration of complementary methods to address the multidimensional nature of malnutrition and chronic disease monitoring.

The pooled proportions of infection in blood donors were 16.6% for Plasmodium spp. and 0.5% for Loa loa. There is a paucity of clinical impact studies on these 'neglected' TTIs, and the available literature suggests impaired levels of immunoglobulin E and albumin. We identified urgent challenges, including awareness among healthcare providers and policymakers, diagnostic and logistical constraints, and low microbial density infections, associated with neglected pathogen-related blood safety.<br><br>CONCLUSION: We opine that providing more epidemiological evidence is crucial to address the above-mentioned challenges for guiding and guaranteeing blood safety in Cameroon.}, }

Such simulations include information on critical structural changes related to diseases, interactions with possible medication, and functionality of proteins. With recently improved speed, accuracy, and accessibility, MD. has become a basic research and drug development tool. From the researcher's point of view, virtual reality has revolutionized how one can conceptualize and interact with molecular structures. Virtual reality (VR) is a method that uses the three-dimensional presentation of biomolecules as manipulable virtual objects for intuitive insight into molecular interactions and structural connections. In this way, virtual technology can be very helpful in investigating complex chemical systems and creating new theories. It facilitates the Cloud-based co-creation of environments in cloud systems for molecular modeling. The same technologies allow real-time research collaboration by sharing and changing virtual molecules. These cooperative situations reward the generation of new ideas and information, which might provide novel discoveries that more direct approaches could not realize. This chapter will discuss the range of computational methods applied to elucidate molecular recognition mechanisms and will cover improved sampling methods and in silico screening. It will also describe how such techniques may be applied to investigate viral proteins and help develop vaccines and drugs during the COVID-19 pandemic. The combination of the predictive power of MD. Simulations with intuitive visualization capabilities from VR would allow researchers to achieve an unprecedented understanding of the molecular origin of many diseases. This should inspire innovation in therapeutic intervention and accelerate discovery in molecular biology.}, }

Physical activity and sleep are modifiable health behaviors that support neurobiological processes underlying learning. While each has been widely examined, research investigating their combined or interactive relationships with learning remains fragmented. This scoping review synthesizes the literature on associations among physical activity, sleep, and cognition in preschool-aged children (3-5 years) and identifies gaps in the integration of these domains.<br><br>METHODS: Electronic databases were searched for peer-reviewed studies published within the past 10 years. Eligible studies included typically developing children aged 3-5 years and examined overlaps between at least two domains: physical activity, sleep, and cognition. Cross-sectional and longitudinal observational studies were included; intervention and review studies, and those conducted during the COVID-19 pandemic, were excluded.<br><br>RESULTS: Thirty-eight studies met the inclusion criteria. Evidence examining physical activity and sleep was limited and inconsistent. Sleep quality indicators (e.g., sleep efficiency and bedtime regularity) were more often reported to be associated with executive function and broader cognitive outcomes than total sleep duration, which showed variable relationships. Findings linking physical activity and cognition were heterogeneous; however, moderate-intensity and cognitively engaging activities were more often reported in association with executive function than total activity or intensity alone.<br><br>CONCLUSIONS: Findings suggest that sleep quality and characteristics of physical activity may be relevant for preschool cognitive outcomes. Greater integration of these domains is needed, and future research should examine physical activity, sleep, and cognition within a single integrated framework to clarify potential interactive pathways linking these behaviors within this evidence base and to inform physical activity recommendations for early childhood development.}, }

Increasing evidence suggests that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection disrupts neuronal redox homeostasis via mitochondrial dysfunction, iron dysregulation, inflammatory signaling, and the depletion of pyridine nucleotide pools. In that context, ferroptosis provides a unifying mechanistic framework linking lipid peroxidation to progressive neuronal injury. This review proposes that neuronal vulnerability might depend not only on the oxidative burden itself but also on the failure of membrane-localized antioxidant defenses. Particular emphasis is placed on the plasma membrane redox system (PMRS), a membrane-associated quinone-reducing network that can support coenzyme Q redox cycling and constrain lipid radical propagation at the plasma membrane. Unlike canonical ferroptosis defense systems that rely predominantly on NADPH, components of the PMRS, particularly cytochrome b5 reductase, can also use NADH, conferring partial metabolic flexibility in conditions of redox stress. We further discuss how SARS-CoV-2-induced NAD[+] depletion might progressively destabilize this membrane-proximal defense architecture, potentially lowering the ferroptotic threshold of vulnerable neurons. Finally, we outline therapeutic strategies that might reinforce PMRS-dependent membrane redox control through NRF2 activation, NAD[+] restoration, coenzyme Q-centered interventions, and modulation of iron-catalyzed lipid oxidation.}, }

This review covers recent progress in mucosal vaccine development. We first discuss the organization of the mucosal immune system, focusing on SIgA induction, tissue-resident memory T (TRM) cells, and resident memory B (BRM) cells. We then examine mucosal adjuvants, from cholera toxin and heat-labile enterotoxin derivatives to stimulator of interferon gene (STING) agonists and a strategy to enhance alum adjuvanticity through neutrophil elastase inhibition. Delivery routes including intranasal, oral, and sublingual administration are reviewed alongside viral vectors, nanoparticles, mRNA-lipid nanoparticles, virus-like particles, and engineered bacterial platforms. The roles of innate immune cells, T helper cell subsets, and the microbiota in shaping vaccine responses are discussed.

While oxygen therapy is lifesaving, accumulating evidence indicates that excessive oxygen exposure can induce significant pathophysiological disturbances, particularly within the cardiovascular and pulmonary systems. Hyperoxia (PaO2 > 100 mm Hg) promotes the generation of reactive oxygen species (ROS), leading to oxidative stress, mitochondrial dysfunction, and the activation of pro-fibrotic pathways. When combined with mechanical ventilation, these effects are further amplified through alterations in intrathoracic pressure, reduced venous return, and increased pulmonary vascular resistance, collectively imposing hemodynamic stress on the myocardium. These mechanical and biochemical perturbations converge to drive structural, functional, and electrical remodeling of the heart, including conduction abnormalities and arrhythmogenesis. Emerging clinical insights, particularly from critically ill and COVID-19 populations, underscore the importance of titrated oxygen strategies that balance adequate tissue oxygenation with minimization of hyperoxic injury. This review synthesizes current evidence on hyperoxia-induced oxidative stress, heart-lung interactions, and mechanisms underlying myocardial remodeling to provide a comprehensive framework for optimizing oxygen therapy.}, }

Herpes simplex virus type 1, human immunodeficiency virus, varicella zoster virus, cytomegalovirus, Epstein-Barr virus, influenza, SARS-CoV-2, West Nile virus, and Zika virus each enter or engage the brain through distinct routes, yet converge on four shared molecular pathways that selectively damage hippocampal circuits: mitochondria-associated membrane (MAM) dysfunction, chronic neuroinflammation, blood-brain barrier (BBB) disruption, and impaired CREB-BDNF signaling. These pathways specifically compromise the dentate gyrus, CA3, and CA1 subfields, producing predictable deficits in pattern separation, associative retrieval, and temporal memory binding. Antiretroviral and antiviral therapies suppress viral replication but fail to reverse organelle-level dysfunction, leaving most hippocampal injury unaddressed. Emerging plasma biomarkers, p-tau217, neurofilament light chain, and GFAP, combined with hippocampal subfield MRI, now enable mechanistic stratification before irreversible circuit loss occurs. This review proposes, as a unifying hypothesis, that virus-associated memory impairment represents a convergent hippocampal syndrome driven by shared downstream pathways, and that combination therapies targeting these pathways simultaneously offer greater therapeutic promise than pathogen-specific approaches alone. The evidentiary basis for this framework varies across pathogens and conditions; direct mechanistic evidence, mechanistic analogy, and preclinical data are distinguished throughout.}, }

Beyond its canonical hemostatic role, PAI-1 has emerged as a pleiotropic mediator of tissue remodeling, fibrosis, metabolic dysfunction, cancer progression, cellular senescence, and age-associated immune dysregulation. A central argument of this review is that PAI-1 should be understood not only as a downstream biomarker of aging-associated pathology, but also as an active effector linking senescence-associated secretory phenotype (SASP) signaling, chronic low-grade inflammation, impaired immune surveillance, fibrotic extracellular matrix remodeling, and a prothrombotic state. In this framework, PAI-1 may function as an immune-aging checkpoint: a molecular node through which senescent, stromal, malignant, and inflammatory cells reinforce immune evasion and tissue dysfunction. Structure-guided drug discovery has enabled the development of small-molecule PAI-1 inhibitors, including TM5275, TM5441, TM5509, and TM5614. Among these, TM5614 is an orally available investigational compound that has progressed to clinical evaluation. Preclinical studies support anti-thrombotic, anti-fibrotic, anti-inflammatory, anti-senescent, and tumor-microenvironment-modulating effects of PAI-1 inhibition, while early clinical studies have evaluated TM5614 in chronic myeloid leukemia, immune-checkpoint-refractory malignant melanoma, non-small-cell lung cancer, and COVID-19-associated pneumonia. This review summarizes the biology of PAI-1, expands the discussion of immunoaging, reviews representative preclinical and clinical data, compares available PAI-1 inhibitors, and discusses the translational opportunities and safety considerations for TM5614 and related compounds.}, }

Prevalence data indicate that approximately one-quarter to one-third of individuals with CF and their caregivers experience clinically significant anxiety or depression. Specifically, pooled global estimates report an anxiety prevalence of 24.9% (95% CI: 20.8-28.9%) and depression prevalence of 13-33% in adults with CF, with caregivers experiencing even higher rates (anxiety: 35-38%; depression: 20-35%). Depression is independently associated with a nearly twofold increase in mortality risk and substantially higher healthcare costs, underscoring its prognostic significance. These mental health comorbidities are consistently associated with reduced treatment adherence, diminished quality of life, increased healthcare utilisation, and decreased survival. Accordingly, psychological well-being has emerged as a key patient outcome that directly shapes engagement with care and the effectiveness of long-term CF management. International CF guidelines now recommend routine mental health screening within multidisciplinary care frameworks. Evidence-based interventions include cognitive-behavioural therapy (CBT), which is endorsed as a primary treatment, although access remains limited, and stepped-care pharmacotherapy, primarily selective serotonin reuptake inhibitors (SSRIs), for moderate to severe symptoms. Telemedicine and other digital health approaches have expanded access to psychological support, with remote CBT and online programmes demonstrating feasibility and symptom improvement during the COVID-19 pandemic and beyond. The advent of CFTR modulator therapies has significantly altered clinical outcomes, enabling many patients to achieve improved lung function and daily functioning. Nevertheless, mental health challenges persist, as individuals navigate new identity shifts and anxieties despite enhanced physical health. The implementation of mental healthcare remains inconsistent; while screening rates have increased, timely follow-up and integrated psychosocial support are frequently insufficient across care centres. This narrative review highlights the ongoing need to integrate mental health management into CF care to optimise adherence, patient outcomes, and long-term survival in the current therapeutic landscape.}, }

Until pre-COVID-19, the most accredited guidelines did not make recommendations for or against the use of these techniques in this clinical condition, and the increased risk of adverse events for patients who failed the non-invasive approach was widely reported in the literature. The most recent guidelines recommend the use of HFNC as a first-line technique in the treatment of de novo acute hypoxemic respiratory failure to avoid the need for tracheal intubation. However, the strength of these recommendations remains weak, the quality of the underlying evidence is poor, and their usefulness in deciding which technique to apply to an individual patient is questionable. Aim: The aim of this review was to provide the reader with some critical tools to interpret the different indications regarding the choice of the best non-invasive support technique to be used in this setting. Methods: To this end, we analyzed the available literature on this topic, privileging the works that are most useful in correlating the practical indications to the pathophysiological assumptions. Results and Conclusions: The notable heterogeneity of the studies on which the current recommendations are based, as well as the affirmation of the concept of patient self-induced lung injury (P-SILI), highlights the importance of assessing each patient's risk of developing this complication, individualizing treatment to the patient's specific needs, and monitoring the patient during treatment.}, }

Following PRISMA 2020 guidelines, studies were classified by geographic scale, modeling approach, data streams, and analytical purpose. The results indicate that Bayesian and compartmental models remained dominant throughout the pandemic, although methodological diversity increased over time with the growing use of machine learning and hybrid frameworks integrating mobility, environmental, and socio-demographic data. Data integration was more common than previously reported. Approximately 30% of studies relied on a single data stream, while 70% incorporated multiple sources, although most multi-source approaches combined only two data types and relatively few studies integrated three or more. Geographic coverage was uneven, with a strong concentration of studies in high-income regions and persistent underrepresentation of low- and middle-income contexts. Models incorporating finer spatial scales and socio-demographic variables more frequently supported geographically targeted interpretation of risk, vulnerability, testing access, and intervention needs. Overall, the findings highlight the importance of multi-source data integration, improved geographic representativeness, and transparent uncertainty communication, alongside the need for FAIR-aligned and equity-aware data infrastructures to strengthen future pandemic preparedness.}, }

This study aims to investigate the impact of a hematological and inflammatory parameter-the platelet-to-lymphocyte ratio (PLR)-on the severity and mortality of COVID-19. Methods: We conducted a comprehensive search of the PubMed database and yielded 75 articles published in the period of 2020-2025, of which 20 studies that evaluated the prognostic value of PLR on hospital admission in COVID-19 patients were included. The review particularly focuses on ROC analyses and reported AUC values. Results: A total of 20 studies were analyzed, including 13 studies assessing disease severity and 14 studies evaluating mortality. Higher PLR values have been observed in patients with a more severe course of COVID-19 compared to those with milder disease, and in non-survivors compared to survivors. However, the literature shows inconsistency regarding the diagnostic utility of PLR based on ROC curve analysis. The reported AUC values ranged from 0.559 to 0.811 for disease severity differentiation and from 0.474 to 0.758 for mortality, which may be related to the heterogeneity of the study populations included in the analysis. Conclusions: PLR may not serve as a direct bridge between inflammation and coagulation in COVID-19-Associated Coagulopathy, but it is indirectly linked to disease severity and mortality, as it reflects changes in both platelet and lymphocyte counts. It is a complementary marker that may assist clinicians in assessing COVID-19 patients but still requires further investigation.}, }

The intrinsic stability of mRNA and its sensitivity to innate immune sensing hinder its capacity for immediate cellular entry, necessitating its need for a delivery system to obtain optimal therapeutic potential. This review explores the innovations in nanocarrier engineering, design principles for lipid nanoparticles-mRNA (LNPs) platforms, and their clinical translation across the prominent indications. It also addresses their safety, immunogenicity, and scalability while addressing the key limitations and manufacturing scalability through comparative platform analysis. Although LNPs usually dominate their delivery through encapsulation and manufacturability, their limitations, like repeat dose reactogenicity and liver tropism, require next-generation designs like SORT lipids, stimuli-responsive hybrids for extrahepatic targeting. In oncology, LNP-mRNA drives the neoantigen vaccines, and rare diseases leverage the transient enzyme replacement. While the safety profiles highlight the innate immune tuning through nucleoside mods and lipid biodegradability, chronic administration risks are still persistent. While there are novel scalability options like microfluidic mixing to support the production gaps in organ selectivity and durability, their adoption is hindered.

The COVID-19 pandemic brought a sharp increase in cases, especially in individuals with diabetes mellitus and those undergoing immunosuppressive treatment, emphasizing significant gaps in our comprehension of disease pathogenesis. Emerging molecular studies have highlighted key virulence factors, such as the CotH family of invasins that facilitate endothelial invasion via interaction with glucose-regulated protein 78 (GRP78), complex iron acquisition systems necessary for fungal growth, and the release of mucoricin, a ricin-like toxin that impairs vascular integrity. Host defense depends mainly on innate immunity, with neutrophils and macrophages working as critical effector cells, while adaptive Th1 and Th17 responses aid in the fungal removal. Mucorales use a variety of immune evasion techniques, such as pathogen-associated molecular pattern (PAMP) masking via cell wall transformations, resistance to phagocytic death, and metabolic utilization of host factors including hyperglycemia and increased free iron in diabetic ketoacidosis (DKA).

Their co-circulation has increased the risk of co-infections, which may result in unpredictable disease progression, increased morbidity, and mortality. This overlap presents a significant challenge in managing outbreaks, as both viruses pose a major public health threat. Vaccines and direct-acting antivirals may be rendered ineffective by viral mutations, making it difficult to address evolving strains. Host-directed antivirals offer a promising alternative, potentially maintaining efficacy against a multitude of variants. Both DENV and SARS-CoV-2 rely on host proteases for viral maturation and entry, with furin playing a crucial role in viral glycoprotein cleavage. In DENV, furin cleaves the prM protein, facilitating virion maturation, while in SARS-CoV-2, the polybasic furin cleavage site in the spike protein enhances viral entry. This makes furin a compelling pan-viral target, where inhibiting furin could reduce viral fitness without relying on viral mutations. This review highlights the therapeutic rationale for targeting furin and discusses luteolin, a furin inhibitor showing antiviral activity against both viruses. Furin-targeted therapies may offer a durable antiviral strategy effective across DENV serotypes, SARS-CoV-2 variants, and co-infection settings.}, }

The demand for testing rapidly exceeded historical norms for respiratory virus diagnostics, necessitating substantial government investment in consumables, assay development, and workforce expansion. This review presents a retrospective evaluation of SARS-CoV-2 diagnostic platforms deployed within the Norfolk and Norwich University Hospital (NNUH) trust and compares them with those implemented by other regional laboratories during the pandemic. It examines the molecular mechanisms, performance, scalability, and specificity of the multiple molecular testing approaches to optimise workflow based on the evolving technology. The integration of complementary platforms through a stratified testing strategy enabled high-throughput population screening while preserving diagnostic resolution for complex respiratory cases, substantially improving laboratory efficiency and resilience. The emerging diagnostic methodologies, RT-LAMP and CRISPR-based assays, are described, and we discuss their potential roles in future outbreaks.

The aim of this review is to assess bat-borne viruses as a potential pandemic risk, with a particular focus on Europe. The presence and activity of bats, as well as diseases emerging in humans in various regions of the world, point to their importance in the context of a possible outbreak of future epidemics. The rate of genetic change observed among viruses requires constant scrutiny on all continents, including Europe. Bats are a considerable source of many zoonotic viruses, including coronaviruses, filoviruses and paramyxoviruses. Among viruses associated with bats, RNA viruses are the dominant ones, characterized by high pathogenicity and often leading to interspecies transmission. The majority (about 80%) of RNA viruses were identified in bats from three families: Vespertilionidae, Rhinolophidae and Pteropodidae. Understanding how viruses are transmitted in the environment and the role of reservoir organisms and intermediate hosts is crucial to determining the level of epidemic risk. This review discuses viruses identified in bats globally, with a special focus on Europe, and evaluates their potential to cause epidemics.}, }

These complexes drive the maturation of pro-inflammatory cytokines IL-1β and IL-18, and initiate gasdermin D (GSDMD)-mediated pyroptosis, a lytic cell death pathway that eliminates intracellular replication niches. This comprehensive review synthesizes the diversified landscape of inflammasome activation during viral infections, extending beyond the canonical NLRP3 inflammasome to include specialized sensors such as NLRP6, NLRP9, NLRP1, NLRP12, and NLRC4. We critically evaluate the evolutionary "arms race" between host defenses and viral pathogens, detailing the sophisticated immune evasion strategies employed by viruses-ranging from the expression of decoy proteins and direct proteolytic cleavage of immune sensors to the manipulation of post-translational modifications (PTMs). Furthermore, we discuss the dual nature of inflammasome activation, which balances protective viral clearance against pathological hyperinflammation, and provide an exhaustive analysis of novel therapeutic strategies, including direct NLR inhibitors and downstream cytokine blockers, currently navigating clinical transition.}, }

Nox are critical components of host defense, generating reactive oxygen species (ROS) that modulate key cellular signaling cascades. Under normal physiological conditions, Nox activity is tightly controlled; however, viral infections frequently disrupt this regulation, leading to aberrant upregulation of specific Nox isoforms. Elevated expression of individual Nox enzymes has been observed in infections such as influenza A and hepatitis C virus, while simultaneous activation of multiple Nox isoforms occurs in HIV and SARS-CoV infections. Similar patterns of dual or multi-isoform Nox activation are also reported in complex disease states, including diabetes, thrombosis, and fibrosis. MicroRNAs play a crucial role in this process by selectively regulating Nox isoform expression during viral infection, thereby remodeling the host redox environment. Nox-derived ROS influence multiple downstream signaling pathways, including SMAD, MAPK, CXCR-mediated signaling, and the JNK/ERK axis, promoting inflammation and fibrosis that worsen viral disease outcomes. Additionally, several FDA-approved drugs, investigational agents, and microRNA-based therapeutics show promise in modulating Nox activity. Therefore, this article substantiates how viral infections reprogram host transcriptomic and redox signaling networks, contributing to viral pathogenesis and offering potential therapeutic intervention strategies.}, }

These viruses induce dysregulated inflammatory responses, typified by cytokine storms that drive extensive tissue damage in pulmonary and extrapulmonary systems, leading to acute respiratory distress syndrome (ARDS) and multi-organ failure. These pathological outcomes are driven by sophisticated mechanisms that manipulate host immune pathways and evade innate and adaptive immune surveillance. The innate immune system plays a pivotal role in the early detection and control of viral infections through mechanisms such as cytoplasmic RNA sensors, Toll-like receptors, interferon signaling, and inflammasome activation. However, these coronaviruses effectively exploit and subvert these processes, suppressing antiviral defenses while amplifying inflammatory cascades. This review delineates the molecular and cellular strategies employed by these pathogens to evade immune recognition and exacerbate immune-mediated tissue injury. Understanding these processes is fundamental for guiding the development of targeted antiviral interventions, immunomodulatory therapeutics, and robust strategies to mitigate the impact of future coronavirus pandemics.}, }

In this review, we integrate recent evidence on Fc effector biology across major viral infections, including severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), influenza virus, human immunodeficiency virus (HIV), Ebola virus (EBOV), and dengue virus (DENV). We discuss how Fc-FcR interactions shape antiviral immune outcomes, modulate vaccine efficacy, and influence the balance between protective immunity and immunopathology, including antibody-dependent enhancement (ADE). We focus on the experimental strategies used to assess Fc-mediated functions and on the inherent limitations of in vitro assays and animal models in defining their physiological relevance in humans. We explore how different vaccine platforms and immunization strategies shape Fc effector profiles, specifically through antibody subclass selection, Fc glycosylation patterns, and engagement with Fcγ receptors. We also summarize emerging approaches to Fc engineering and glycan modification that aim to enhance antibody efficacy while limiting adverse immune activation. This review summarizes current understanding of Fc effector functions in antiviral immunity and discusses their relevance for the design of next-generation vaccines and antibody-based therapies.}, }

With the increase in MMD following the COVID-19 pandemic, there is a dearth of data on its impact on HIV care outcomes, such as viral suppression. Therefore, we conducted a qualitative systematic review to explore how PLWH and healthcare workers (HCWs) perceive the uptake, barriers, challenges, and benefits of MMD, as well as its effects on viral suppression.<br><br>METHODS: In January 2025, following the PRISMA approach, we searched CINAHL, Embase, PubMed, and Scopus databases for articles. Two reviewers independently performed the screen, extraction, and appraisal processes. We descriptively reported the findings in line with our objectives.<br><br>RESULTS: Of the 3521 studies found, only 15 were included in this review, and most were from sub-Saharan Africa. HCWs initiated PLWH on MMD because of the COVID-19 pandemic, particularly to reduce clinic traffic, even when they did not meet the criteria for MMD. The barriers to PLWH initiating MMD, confirmed by HCWs, include privacy concerns and the stigma associated with having multiple antiretroviral therapy (ART) medication bottles and the stockout of ART medications in clinics. Furthermore, some PLWH refused MMD because plenty of ART bottles can increase the risk of unintended HIV disclosure. Confirmed by HCWs, PLWH share their medication with others and, at times, misuse it. Regarding MMD benefits, PLWH reported job stability as a benefit because of reduced permission from work to refill ART medication and waiting time in the clinics, a decrease in stigma and discrimination, and a generally improved HIV care experience; all confirmed by HCWs. Furthermore, HCWs reported benefits, including reduced workload and burnout. Interestingly, unlike PLWH's claim that MMD improved adherence and viral suppression, HCWs reported the opposite.<br><br>CONCLUSION: The COVID-19 pandemic increased MMD rollout to those who met and those who did not meet its criteria, leading to shorter waiting times, job stability, and reduced HCWs' burnout.

The epidemiology of KS is likely underestimated due to diagnostic overlap with other cardiac and allergic conditions and limited awareness across medical specialties. This narrative review focuses on the distinctive features of KS in special populations, emphasizing how patients' age, comorbidities, immune status, and vascular substrate modify presentation, diagnosis, and outcomes. In elderly patients, polypharmacy, increased plaque vulnerability, and endothelial dysfunction favor Type II and III KS. Pediatric cases, although rare, are predominantly Type I and strongly associated with food allergies, insect stings, vaccines, and antibiotics, with under-recognition driven by diagnostic bias and ethical concerns surrounding invasive testing. Patients with coronary stents, cardiac devices, chronic kidney disease, and those receiving dialysis exhibit heightened susceptibility due to chronic inflammation, foreign-body hypersensitivity, and prothrombotic states. Pregnancy and the peripartum period represent a unique immuno-hemodynamic milieu in which Th2 immune shift, increased coronary vasoreactivity, and obstetric triggers can compromise both maternal and fetal perfusion. Additional risk modulation is observed in atopic individuals, asthmatics, patients with autoimmune, inflammatory, oncologic, psychiatric, and neurodevelopmental conditions, as well as in COVID-19 and post-infectious states. We propose a host-modified framework for KS that complements traditional classification by integrating immune phenotype and vascular substrate, enabling improved risk stratification and personalized preventive strategies.}, }

The need for a new study is justified by six key reasons: 1) Monitoring the secular evolution of the disease. 2) Evaluating the impact of new exposures (pollution, vaping, etc.) and phenotypes (COPD in non-smokers, pre-COPD, etc.). 3) Integrating novel tests such as low-dose CT scans or biomarkers for earlier and more accurate diagnosis. 4) Validating new screening tools. 5) Evaluating the quality of care and the burden of disease in the post-COVID-19 era. 6) Creation of a prospective cohort for translational research.

In England, the principal public source for routine surveillance is the NHS England Quarterly Monitoring of Cancelled Operations (QMCO) collection, but direct comparison between NHS trusts and independent-sector providers remains methodologically difficult. This revised narrative review synthesised 10 publicly available NHS England datasets/documents and 13 supporting peer-reviewed or policy sources relevant to elective surgery cancellation and independent-sector provision. Publicly available national time-series data show that last-minute non-clinical cancellation rates have generally remained around 1% of elective admissions since the early 2000s, whereas the proportion of cancelled patients not treated within 28 days increased substantially after the COVID-19 pause in data collection. In the latest official commentary, 21,456 operations were cancelled at the last minute in the third quarter (Q3) 2025/26, and 4,821 patients (22.5%) breached the 28-day standard. Recent provider files identify only a small number of independent-sector organisations. Across the public extracts reviewed from 2021/22 to 2025/26 (Q1-Q3), identifiable independent-sector providers accounted for 296 cancellations versus 337,004 in NHS organisations, contributing under 0.2% of recorded cancellations in each year examined. However, the public files do not provide matched provider-level denominators or case-mix adjustment, and the reporting scope has changed over time. The main conclusion is therefore methodological: current public English data are suitable for surveillance of NHS-funded last-minute cancellations, but they do not permit a fair denominator-matched comparison of day-of-surgery cancellation rates between NHS trusts and private providers. Future comparative work will require linked activity denominators, transparent provider classification, and standardised sector-wide reporting.}, }

Among the critical determinants of COVID-19 vaccine uptake, confidence in the vaccine's efficacy and safety was a significant consideration. Geographic access to vaccination sites hindered uptake; for example, only 9.7% were vaccinated in a hard-to-reach county, compared to 53% in an urban county. Sociodemographic factors, including age, gender, level of education, occupation, and co-morbidity, significantly influenced vaccine uptake in Kenya. Above all, the Ministry of Health's failure to mount a convincing response to myths and misconceptions about the COVID-19 vaccine ultimately affected vaccination coverage nationwide.<br><br>CONCLUSION: Future preparedness must ensure inclusive vaccine strategies led by governments with clear policies and tailored outreach.

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), Influenza A Virus (IAV), and Mycoplasma pneumoniae (MP), as three representative respiratory pathogens, all clinically cause airway epithelial shedding, ciliary dysfunction, and Acute Respiratory Distress Syndrome (ARDS). Notably, they are the common triggers of acute respiratory infections characterized by persistent and severe cough, a clinical hallmark rooted in the structural disintegration of the airway mucosal barrier. However, the molecular mechanisms by which they compromise the airway mucosal barrier exhibit significant heterogeneity. Currently, there is a paucity of systematic reviews offering a comparative analysis between these viral and atypical bacterial pathogens. This review comprehensively examines the pathogenic mechanisms of these three agents across four dimensions: receptor recognition, direct cytotoxicity, immunopathology, and abnormal tissue repair. Studies indicate that during the invasion phase, SARS-CoV-2 relies on the Angiotensin-converting enzyme 2 (ACE2) receptor and Transmembrane protease, serine 2 (TMPRSS2) -mediated membrane fusion; IAV identifies sialic acid receptors via hemagglutinin, whereas MP utilizes specialized attachment organelles for "gliding" colonization. Regarding cellular injury mechanisms, SARS-CoV-2 primarily hijacks the endoplasmic reticulum (ER) to induce stress responses and promote syncytium formation; IAV predominantly targets mitochondria to trigger apoptosis and cellular necrosis; while MP utilizes hydrogen peroxide and Community-Acquired Respiratory Distress Syndrome (CARDS) toxin to implement oxidative damage and vacuolating toxicity. At the immunopathological level, SARS-CoV-2-induced delayed interferon response and cytokine storm, IAV-triggered excessive formation of neutrophil extracellular traps (NETs), and MP-mediated activation of the NOD-like receptor thermal protein domain associated protein 3 (NLRP3) inflammasome are key drivers exacerbating airway injury. Furthermore, distinct acute injury mechanisms determine differentiated long-term prognoses, such as pulmonary fibrosis, airway hyperresponsiveness, and airway remodeling. In summary, elucidating the commonalities and specificities of these mechanisms has significant clinical guidance value for precisely distinguishing clinical phenotypes, predicting disease progression, and developing host-directed therapies targeting specific injury pathways.}, }

The study introduces the "Pandemic Response Pentad," an original conceptual model positioning Legislation as the foundational core, mediated by Governance, to drive three interconnected field operations. Based on this framework, Korea's infectious disease control system is evaluated across four operational domains: (1) governance reform and personnel structure enhancement, (2) epidemiological response capabilities and data utilization, (3) medical response system, including vaccination programs and supply stockpiling, and (4) social response mechanisms, encompassing social distancing and the protection of vulnerable populations. While rapid legislative enactments enabled effective disease control, they also generated profound ethical tensions regarding fundamental human rights. To mitigate these unintended socioeconomic consequences, Korea institutionalized extensive statutory compensation mechanisms for healthcare facilities, small business owners, and vaccine injuries. The findings highlight that advancing national research infrastructure and establishing policy-oriented think tanks for future pandemic preparedness strictly require proactive legislative backing. Ultimately, this study provides valuable insights into the critical interplay between legal mandates and institutional resilience in global health crisis management.}, }

All population-based observational studies reporting incidence or prevalence measures of PNH were included, with no restrictions on age or geography; the synthesis of results focused on studies evaluated as medium or high-quality based on a structured assessment.<br><br>RESULTS: The annual incidence of patients diagnosed with PNH ranged from 0.17 to 0.35 per 100,000 population between 2002 and 2022 in the majority of high-quality studies. Regional variability emerged: studies from countries with high healthcare system quality scores consistently reported higher incidence estimates than those from countries with low scores. Yearly prevalence estimates in 2010-2021 ranged from 1.1 to 2.1 per 100,000 population, while longer-period prevalence (10-17 years) ranged from 1.5 to 6.4 per 100,000 population.<br><br>DISCUSSION: The prevalence of diagnosed PNH has been steadily growing since 2006 across all regions, possibly reflecting improved survival rates following the introduction of effective therapies or improved diagnostic practices. Despite disruptions observed during the COVID-19 pandemic (2020-2021), this upward trend is expected to continue as treatment access improves globally. The lower incidence reported in the regions with lower healthcare quality scores reflects potential underdiagnosis of PNH or unequal access to healthcare, highlighting the need for strengthening healthcare systems to ensure timely diagnosis and access to treatment of PNH.<br><br>CONCLUSIONS: This review provides updated global estimates of the incidence and prevalence of PNH, offers new insights into epidemiological trends, and highlights potential regional inequities in diagnosis and treatment.

The emergence of widespread resistance in the major malaria parasite (Plasmodium falciparum) to first-line treatment drugs has highlighted the need for new antimalarials and smarter drug delivery strategies. Nevertheless, recent successes of the first malaria vaccines (RTS,S/AS01 and R21/MM) have renewed the promise of widely applicable vaccines in the future. Since 2015, the Eastern Mediterranean Region has experienced an overall increase in malaria cases and deaths. In the Arabian Peninsula, while most of the Gulf Cooperation Council (GCC) countries have been declared free of indigenous malaria (Bahrain, Kuwait, Qatar, and the United Arab Emirates), malaria is still endemic in two GCC countries (Saudi Arabia and Oman) and their neighbors (Yemen). Furthermore, a number of factors threaten malaria control in this region, especially antimalarial drug resistance, the emergence of highly invasive mosquito species, increasing average temperatures, and imported malaria.

Its pathogenic mechanisms involve viral persistence, chronic inflammation, immune dysregulation, endothelial dysfunction, and endocrine/metabolic abnormalities. Currently, no specific diagnostic tests exist for LC, highlighting the need for reliable biomarkers. This review synthesizes current evidence on hormonal, metabolic, and metabolite biomarkers in LC. While vitamin D deficiency is prevalent in LC, being associated with neurocognitive symptoms, delayed recovery and poor physical performance, particularly in older adults, its lack of specificity reduces diagnostic utility. Insulin resistance markers consistently correlate with fatigue, mood disturbances, and myalgia, suggesting a distinct metabolic LC phenotype. Lower cortisol frequently correlates with fatigue, sensory disturbances, and neurocognitive symptoms. Alterations in cortisol/adrenocorticotropic hormone, growth hormone, prolactin, and gonadotropins suggest a potential hypothalamic-pituitary axis involvement; however, these abnormalities are often transient, dynamic or nonsignificant. While some patients may exhibit low free triiodothyronine associated with fatigue, no significant incidence of thyroid dysfunction and autoimmunity was associated with LC. Despite the absence of a distinct and consistent metabolomic signature, LC is characterized by the activation of the kynurenine pathway, including increased kynurenine and quinolinic acid, being associated with fatigue, neurocognitive and depressive symptoms. Emerging metabolites of mitochondrial dysfunction and lipid metabolism alterations require further validation. Despite promising findings, evidence remains scattered, hindered by small sample sizes and methodological limitations. Future research should prioritize standardization of biomarker assessment, validation in diverse populations, and exploration of targeted therapeutic interventions.}, }

This study systematically analyzed a decade (2014-2023) of national surveillance data from mainland China, encompassing 50,434 outbreaks, 311,672 illnesses, and 1330 fatalities. The results revealed pronounced geographical disparities, with five provinces (Shandong, Yunnan, Hunan, Guizhou, and Sichuan) collectively accounting for 59.27% of outbreaks. A distinct seasonal peak was observed from June to August, correlated with high temperature and humidity. Poisonous mushrooms were the predominant causative agent, responsible for 50.65% of outbreaks with identified etiology and the highest case fatality. Microbial pathogens, notably Vibrio parahaemolyticus and Salmonella spp., were also major contributors. Most outbreaks and fatalities occurred in household settings, with a notable surge during the COVID-19 pandemic.

Patients requiring dialysis are especially at risk because their survival depends on regular access to complex, resource-intensive treatment. While disaster nephrology literature increasingly addresses preparedness and resilience, it remains unclear how explicitly this literature addresses patient-centered care.<br><br>OBJECTIVE: To map the literature on patient-centered care for patients requiring dialysis during disasters and public health emergencies, with attention to preparedness, continuity of care, communication, access, and vulnerable populations.<br><br>METHODS: A scoping review was conducted using searches in Web of Science, Scopus, and PubMed. Search terms combined concepts related to disaster, emergency, patient-centered care, vulnerability, dialysis, and alternative care facilities. Records were screened for relevance to dialysis care in disasters or public health emergencies, or for conceptual relevance to patient-centered dialysis care in disrupted settings. Both authors conducted screening, eligibility assessment, and data charting, using a predefined set of inclusion criteria and a consistent conceptual framework. The search was intentionally focused to prioritize literature most directly relevant to dialysis-dependent patients in disaster and public health emergency contexts. Forty-three studies were included.<br><br>RESULTS: The included studies comprised reviews, scoping reviews, observational studies, qualitative studies, case studies, program reports, pilot studies, trials, and conceptual papers. The literature clustered around six themes: preparedness for dialysis patients and providers; continuity of care and treatment access; infrastructure, logistics, and resilience; patient awareness, communication, and lived experience; public health emergency adaptations, particularly during COVID-19; and broader frameworks for disaster risk reduction in kidney care. Although relatively few studies explicitly used the term patient-centered care, many addressed closely related domains, including communication, care planning, family involvement, psychosocial support, access, and continuity. Taken together, the findings suggest that patient-centered dialysis care in emergencies is shaped by broader health system factors, including preparedness, coordination, service design, and equity.<br><br>CONCLUSIONS: Patients requiring dialysis are among the most vulnerable groups during disasters and public health emergencies. Existing literature provides a strong foundation in preparedness and continuity of treatment but addresses patient-centered care more often implicitly than explicitly. Future research should develop and test patient-centered indicators for dialysis care in emergencies, including communication, shared planning, caregiver involvement, psychosocial support, and the role of alternative care facilities.}, }

Growing epidemiological and mechanistic evidence implicates neurotropic viral exposomes, defined as cumulative lifetime viral infections, as significant contributors to AD risk. Viral encephalitis and common viral infections, including herpes simplex virus type 1 (HSV-1), human immunodeficiency virus (HIV), cytomegalovirus (CMV), SARS-CoV-2, and influenza, have been associated with an increased incidence of AD/ADRD; however, the molecular mechanisms underlying these associations remain incompletely understood.<br><br>METHODS: A systematic literature review was conducted using PubMed, Web of Science, Scopus, and Google Scholar (1990-2025) to identify epidemiological, experimental, and mechanistic studies linking viral infections to AD-related pathology. Systems biology approaches were applied using Cytoscape, STRING, KEGG, WikiPathways, and Ingenuity Pathway Analysis to construct protein-protein interaction networks and identify convergent biological processes shared between AD and viral host-response pathways. Functional enrichment analyses focused on neuroinflammation, amyloid-&#x3b2; (A&#x3b2;) metabolism, tau pathology, autophagy, and blood-brain barrier (BBB) integrity.<br><br>RESULTS: Across diverse viral infections, strong convergence was observed in innate immune activation pathways, including microglial priming and NLRP3 inflammasome signaling, accompanied by chronic production of proinflammatory cytokines (IL-1&#x3b2;, TNF-&#x3b1;, IFN-&#x3b3;). Multiple viruses modulated amyloidogenic APP processing, impaired A&#x3b2; clearance, promoted tau hyperphosphorylation, disrupted autophagy-lysosomal systems, and compromised BBB integrity. Systems-level analyses revealed overlapping signaling hubs, including NF-&#x3ba;B, MAPK, PI3K-Akt, and cGAS-STING that amplify neurodegenerative cascades, with effects most pronounced in genetically susceptible populations such as APOE4 carriers.<br><br>CONCLUSIONS: Collectively, current evidence supports a mechanistic link between viral exposomes and AD/ADRD mediated through convergent neuroinflammatory, and proteostatic pathways. Although viral infections alone are unlikely to be sufficient to cause AD, recurrent or persistent viral exposures may act as potent disease modifiers that accelerate neurodegenerative processes. Integrating viral biomarkers, genetic risk stratification, and systems biology approaches offers promising opportunities for early diagnosis, prevention, and development of mechanism-guided therapeutic strategies.}, }

The COVID-19 pandemic exposed the risks of highly concentrated production systems and underscored the need for locally anchored manufacturing models capable of responding rapidly to public health emergencies. The Pasteur Network (PN)-a global consortium of 32 public health and research institutes across Africa, Asia, Europe, and the Americas-offers an operational example of decentralized vaccine manufacturing embedded in national public health systems linking regional manufacturing capacity with public health priorities. Here, we examine the contributions and challenges of members within the PN engaged in vaccine manufacturing. Twelve members currently produce more than 525 million doses annually, covering a broad range of human and veterinary vaccines. Embedded within national health systems, the PN members combine research, development, and partial or end-to-end manufacturing capacities, ensuring close alignment with national public health priorities. Several members within the PN also contribute to global initiatives, including the Coalition for Epidemic Preparedness Innovations (CEPI) manufacturing network, reinforcing their role in global preparedness efforts. Despite these strengths, common barriers persist across the PN, including workforce retention challenges, limited sustainable core funding, supply chain vulnerabilities, fragmented regulatory pathways, and insufficient coordination. We argue that the PN illustrates a scalable, public-health-embedded manufacturing model that complements existing industrial and technology-transfer approaches and should inform future global financing and governance.}, }

Advancing age is accompanied by progressive dysfunction of both innate and adaptive immunity, resulting in impaired responses to pathogens and elevated morbidity and mortality. Cellular senescence, a state of permanent cell-cycle arrest with extensive molecular and phenotypic changes, including chromatin remodelling and the senescence-associated secretory phenotype (SASP), has emerged as a key factor in this process. Though initially protective as a tumor-suppressive mechanism, senescence becomes maladaptive with age, contributing to inflammaging, immune dysregulation, and heightened susceptibility to infection. In ocular diseases, such as age-related macular degeneration and chronic keratitis, senescent cells in retinal pigment epithelium and corneal tissues drive persistent inflammation and fibrosis, exacerbating vulnerability to opportunistic pathogens. Pathogens can exploit senescent cells through virulence factors and persistent inflammatory responses, thereby promoting chronic infection and even age-related diseases. Conversely, senescent cells and their SASP can intensify infection severity, as shown in viral infections such as SARS-CoV-2 and bacterial pathogens including Streptococcus pneumoniae and Mycobacterium tuberculosis. This reciprocal relationship illustrates how infection accelerates cellular aging while aging predisposes individuals to more severe infections. Emerging therapeutic strategies targeting senescence, including senolytics and senomorphics, hold promise for mitigating infection-related pathology. In parallel, vaccines and immunotherapies tailored to the aging immune system will be crucial for reducing infection burden in older populations. This review integrates current evidence on the bidirectional interplay between senescence and infection, emphasizing its clinical relevance and potential for translational intervention.}, }

Observational studies comparing RRD patients during COVID-19 LDs or pandemic periods with pre-pandemic controls were included.

Meta-analyses were performed for comparable outcomes using random- or fixed-effects models based on heterogeneity.<br><br>RESULTS: Twenty-nine observational studies involving more than 116,000 eyes were included. COVID-19-related restrictions were associated with a significant reduction in RRD surgical volume (rate ratio 0.71; 95% CI: 0.60-0.84), although marked regional heterogeneity was observed. Marked heterogeneity across studies appeared to be partly related to differences in LD severity, duration, and regional healthcare system burden. Patients presenting during LD periods were significantly less likely to have macula-on RRD (OR = 0.61; 95% CI: 0.46-0.83) and more likely to exhibit moderate-to-severe proliferative vitreoretinopathy (PVR) (OR = 2.58; 95% CI: 1.37-4.87) compared with pre-LD periods. Time from symptom onset to surgery increased during LD periods, while presentation-to-surgery intervals decreased.

As a critical initiator of PANoptosis and a sensor of Z-nucleic acids (e.g., viral RNA replication intermediates), ZBP1 has garnered growing attention in recent years for its critical involvement in various inflammatory diseases. By integrating current research progress, this review further explores the functional roles of ZBP1 in distinct inflammatory diseases and its potential value as a novel therapeutic target. Through systematic collation and analysis of recent studies on the regulatory mechanisms of ZBP1 in systemic inflammation, this review covers a broad range of disease areas, including neuroinflammation, diseases of the digestive, musculoskeletal, circulatory, and endocrine systems, as well as autoimmune diseases, sepsis, and bone marrow failure. Comprehensive analysis of these studies further elucidates the common regulatory mechanisms and disease-specific roles of ZBP1 in diverse inflammatory diseases. ZBP1 exerts diverse functions in inflammatory diseases across multiple organ systems. In the nervous system, it exacerbates brain injury and neuroinflammation by activating the RIPK3 (receptor-interacting protein kinase 3)-MLKL (mixed lineage kinase domain-like protein)-dependent necroptosis pathway. In digestive system diseases, it contributes to the pathological processes of periodontal disease and non-alcoholic steatohepatitis by regulating pyroptosis and inflammatory responses. In the musculoskeletal system, it accelerates the progression of osteoarthritis by facilitating chondrocyte damage and inflammation. In the circulatory system, it mitigates inflammatory responses in myocarditis and heart failure by inhibiting the activation of RIPK3 and NF-κB signaling pathways. In the endocrine system, it is implicated in the development of type 2 diabetes by regulating inflammatory responses and insulin resistance. In the respiratory system, it mediates programmed cell death and inflammatory responses by activating pathways such as ZBP1-RIPK3-MLKL, thereby participating in lung injury processes in diseases such as asthma, ARDS, and COVID-19. In the immune system, it aggravates the pathological progression of systemic lupus erythematosus and rheumatoid arthritis by triggering inflammatory cell death and related signaling pathways. ZBP1 exerts a pivotal role in the onset and progression of systemic inflammation by regulating inflammatory responses and tissue damage through multiple cell death and inflammatory signaling pathways. These findings not only offer novel insights into the mechanistic underpinnings of ZBP1 in systemic inflammation but also lay a theoretical basis for developing ZBP1-targeted therapeutic strategies. Future research should further elucidate the disease-specific mechanisms of ZBP1 in distinct inflammatory disorders and assess its therapeutic potential, thereby providing novel directions and strategies for the management of systemic inflammation- associated diseases.}, }

CRISPR-based diagnostics are uniquely positioned to enable rapid, affordable, and highly accurate nucleic acid testing at both the point-of-care and the point-of-need. In this review, we discuss advances toward deployable CRISPR-based diagnostics. We begin by examining innovations in sample processing methods, emphasizing strategies that reduce equipment requirements and enhance compatibility across diverse sample types and pathogens. We then explore developments in one-pot isothermal and amplification-free approaches, comparing the benefits and tradeoffs associated with each, as well as multiplexing strategies for simultaneous detection of multiple pathogens. Finally, we consider additional factors that impact assay deployability, including reagent lyophilization to minimize cold chain dependence and readout technologies that enable detection in resource-limited settings. We conclude by outlining remaining challenges and opportunities for future progress.}, }

Saudi Arabia's healthcare journey has included major milestones, including the founding of the Ministry of Health in 1951, national immunization programs, the expansion of hospital infrastructure, and the introduction of primary healthcare services. Each era of national development contributed to shaping a system that today serves a rapidly growing and diverse population. Major reforms under the reigns of King Khalid, King Fahd, and King Abdullah significantly improved healthcare access, quality, and health outcomes. These reforms were supported by evolving governance mechanisms, including centralized administration through the Ministry of Health, national development planning, expanded public financing, and regulatory frameworks guiding healthcare delivery. In the contemporary period, under Vision 2030, healthcare transformation has accelerated through initiatives emphasizing public-private partnerships and sustainable financing. Digital health has expanded through national electronic health records, telemedicine platforms, integrated health information systems, and emerging artificial intelligence applications. The healthcare system has also demonstrated resilience in responding to challenges such as the MERS-CoV and COVID-19 pandemics, as well as the health demands of the Hajj pilgrimage. Despite substantial progress, challenges remain, including regional disparities, rising non-communicable diseases, and workforce sustainability. The Saudi experience offers important policy and leadership lessons for countries pursuing large-scale health system reform.}, }

Common effects include enhanced anaerobic glycolysis, depletion of key amino acids, activation of the kynurenine pathway, and disruption of purine signaling. However, each virus leaves a distinct metabolic fingerprint. SARS-CoV-2 infection leads to glucose accumulation, alters late-stage Krebs cycle metabolites, and significantly disrupts nucleotide production. In contrast, influenza viral infection depletes glucose and dampens Krebs cycle activity, with a less consistent impact on nucleotide pathways. Viral proteins, such as SARS-CoV-2 ORF3a and influenza virus NS1, play a crucial role in these metabolic shifts. These changes not only reflect viral strategies but also correlate with disease severity. As metabolomics technologies advance, understanding these virus-specific and shared metabolic changes could unlock new diagnostic tools, prognostic markers, and treatment strategies.}, }

However, over the past two decades, the landscape of infectious diseases in this population has evolved substantially, marked by an increasing burden of emerging and re-emerging pathogens. The global rise in multidrug-resistant bacteria and fungi has complicated antimicrobial management and limited therapeutic options. Concurrently, novel and re-emerging viral threats, most notably severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and other opportunistic viruses have been associated with severe disease, graft dysfunction, and prolonged hospitalization in immunocompromised children. Declining vaccination coverage has further contributed to the resurgence of vaccine-preventable infections such as measles and pertussis, which often present a more aggressive clinical course in PTR. Rare but consequential emerging pathogens, including arboviruses, hepatitis E virus, polyomaviruses, lymphocytic choriomeningitis virus, Enterovirus D68, Mpox (monkeypox virus), avian influenza A(H5N1), and emerging fungi, pose additional risks through both donor-derived transmission and community exposure, particularly in endemic and resource-limited settings. Broader global factors, including climate change, increased travel, and population displacement, have expanded pathogen distribution and exposure risk. Simultaneously, advances in molecular and syndromic diagnostics have improved pathogen detection, identifying infections previously under-recognized in transplant populations. These evolving epidemiological trends highlight the importance of ongoing surveillance, improved vaccination strategies, antimicrobial stewardship, and individualized prevention and treatment approaches. This comprehensive review synthesizes current evidence on most encountered and rare emerging and re-emerging bacterial, viral, and fungal infectious diseases affecting PTR.}, }

Studies that assessed oral curcumin in combination with piperine and reported results related to oxidative stress, inflammation, metabolism, cardiovascular disease, or clinical symptoms were considered eligible. Using accepted methodological standards, the risk of bias was evaluated.<br><br>RESULTS: There were 20 RCTs with sample sizes ranging from 8 to 117 individuals and durations ranging from 1 to 12&#x202f;weeks. Doses of piperine (5-15&#x202f;mg/day) and curcumin (500-1,500&#x202f;mg/day) varied. Fifteen out of twenty trials indicated significant decreases in inflammatory biomarkers [C-reactive protein (CRP), high-sensitivity CRP (hs-CRP), and interleukin-6 (IL-6)]. Of 15 studies evaluating these outcomes, 12 showed improvements in oxidative stress markers, including superoxide dismutase (SOD), total antioxidant capacity (TAC), and malondialdehyde (MDA). Supplementation dramatically decreased fasting blood glucose (FBS), glycated haemoglobin (HbA1C), and Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) in individuals with metabolic syndrome (MetS) and type 2 diabetes. At the same time, 14 out of 18 trials showed reductions in lipid markers (triglycerides (TG), LDL-C, total cholesterol, and HDL-C). After coronary artery bypass grafting and acute myocardial infarction (AMI), cardiovascular populations showed decreases in cardiac damage biomarkers (CK-MB, AST, and ALT). COVID-19, premenstrual syndrome (PMS), dysmenorrhea, and chronic pulmonary illness all showed symptom-based improvements. No significant adverse effects were noted.

MEDLINE, EMBASE, CINAHL, and Scopus were searched from inception to July 2025. Eligible qualitative and mixed-methods studies examined barriers and facilitators to returning to work among working-age adults with post-COVID condition or healthcare professionals involved in their care. Data were synthesized using critical interpretive synthesis, informed by the International Classification of Functioning, Disability and Health framework.ResultsTwenty-nine qualitative or mixed-methods studies (n=1902 participants) were included. Barriers and facilitators operated across domains within broader organizational and systemic contexts. Fluctuating, unpredictable symptoms were major barriers, while gradual rehabilitation and energy management facilitated return to work. Mismatches between work capacity and job demands limited work participation. Environmental barriers included stigma, inflexible policies, limited accommodations, and financial or compensation pressures, while facilitators included flexible work arrangements, supportive leadership, and collaborative planning. Guilt and fear of underperformance were personal barriers, while acceptance and motivation facilitated return to work. Specialists identified fragmented services and limitations of current care models as systemic concerns.ConclusionsPost-COVID condition necessitates flexible, multidisciplinary return-to-work models that accommodate symptom variability and address psychosocial needs.

Traditional pathogen-specific vaccines, although effective for individual diseases, face significant limitations in addressing EIDs due to long development timelines, resource intensity, and restricted adaptability to novel pathogens or variants. Pan-pathogen vaccines-designed to provide broad-spectrum immunity across multiple related or unrelated pathogens-offer a transformative approach to pandemic preparedness. This review presents a comprehensive overview of pan-pathogen vaccinology within the One Health framework, emphasizing the integration of human, animal, and environmental health for proactive disease prevention. We provide explicit definitions for "universal", "broad-spectrum", and "pan-pathogen" vaccines and embed the One Health principle into the full vaccine development lifecycle through real-world case studies, including Nipah virus and rVSV-Ebola. The review highlights strategies for epitope discovery using comparative genomics, evolutionary biology, and immunoinformatics to identify conserved antigenic regions, and details mechanisms of cross-protective immunity mediated by T cells, broadly neutralizing antibodies, mucosal responses, and trained innate immunity with emphasis on their interplay. Advanced vaccine platforms-mRNA, viral vectors, protein subunits, and nanoparticle-based systems-are evaluated for their capacity to deliver multivalent, chimeric, and mosaic antigens. Preclinical and clinical advances against influenza, coronaviruses, flaviviruses, filoviruses, and critically, bacterial, fungal, parasitic, and DNA virus targets are summarized. Ethical, regulatory, and global health considerations for equitable vaccine distribution are discussed, with expanded safety analysis addressing pan-pathogen-specific hazards such as antigenic competition, autoimmunity, and regulatory adaptation. Persistent gaps, including antigenic variability, immune imprinting, safety concerns, and challenges in clinical validation, are identified, alongside controversies surrounding the balance between broad coverage and potential immune escape. Integrating genomic surveillance, predictive modeling, and emerging technologies such as artificial intelligence, systems biology, and synthetic vaccinology is essential to optimize vaccine design and accelerate translational implementation. Collectively, pan-pathogen vaccines represent a proactive, adaptive, and globally coordinated strategy to mitigate future pandemics and strengthen long-term health security.}, }

These cells exhibit remarkable plasticity, enabling them to adopt distinct phenotypes and functional profiles in response to changes in their microenvironment. Biological barriers, such as the blood-brain barrier (BBB) and the intestinal barrier, play a crucial role in maintaining the organism's homeostasis, protecting organs and tissues against pathogens, toxins, and other external factors. Alterations in the permeability of the BBB and the intestinal barrier expose microglia to peripheral molecules, such as cytokines, LPS, and bacterial metabolites. These molecules reach the CNS via systemic circulation, activating microglia through Toll-Like Receptor (TLR) and Nod-like receptor family pyrin domain-containing (NLRP) receptors and lead to a transition in microglial phenotype. Elucidating bidirectional communication between these barriers and microglia holds significant potential for developing novel therapeutic targets, particularly in neurological disorders with limited treatment options.

The Coronavirus Disease 2019 (COVID-19) pandemic, caused by Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2), highlights the interconnectedness of human, animal, and environmental health within the One Health framework. The intestinal microbiome plays a central role in host immunity and systemic homeostasis, and its disruption has been linked to altered disease severity and recovery patterns in COVID-19. Evidence suggests that SARS-CoV-2 infection induces intestinal dysbiosis, modifies immune signaling, and affects the microbiota-gut-brain axis (MGBA), contributing to neuropsychiatric and metabolic complications. This review synthesizes current findings on the intestinal microbiome's role in COVID-19 pathophysiology and recovery, explores emerging therapeutic strategies including probiotics, prebiotics, and fecal microbiota transplantation, and emphasizes the importance of integrating microbiome research into pandemic preparedness through a One Health approach.}, }

Among commonly prescribed ASMs, carbamazepine, valproate, and levetiracetam have been implicated in modulating oxidative stress-related signaling pathways, including Nrf2, NF-κB, and MAPK. Ascorbic acid, a potent antioxidant capable of crossing the blood-brain barrier, has emerged as a promising therapeutic candidate. This review examines the molecular mechanisms underlying ASM-associated oxidative stress in clinical, non-kindled/kindled preclinical, as well as non-epilepsy models, and highlights evidence demonstrating the ability of ascorbic acid to attenuate ROS accumulation, enhance endogenous antioxidant defenses, and modulate redox-sensitive signaling pathways implicated in epileptogenesis and ASM-induced toxicity. Collectively, the available evidence suggests that ascorbic acid has the potential to confer neuroprotection and reduce oxidative injury in epilepsy. Insights presented in this review aim to initiate research focusing on ascorbic acid as an adjuvant in epilepsy. Further studies are warranted to clarify its interactions with ASM metabolism, to optimize dosing strategies, and to establish its translational potential as an adjuvant therapy in clinical epilepsy management.}, }

The co-occurrence of AAV and Evans syndrome (ES) is exceptionally rare and may reflect broader immune dysregulation. A 72-year-old female presented with progressive right-sided hemiplegia and mixed aphasia. Imaging revealed multiple acute cerebral infarcts. Laboratory findings showed anemia, thrombocytopenia, acute kidney injury, and elevated inflammatory markers. Serology confirmed myeloperoxidase (MPO)-ANCA positivity, supporting a diagnosis of AAV, most consistent with microscopic polyangiitis. Subsequent hematological workup supported concurrent autoimmune cytopenias consistent with probable ES. Despite corticosteroids and intravenous immunoglobulin, her condition deteriorated with left middle cerebral artery occlusion; during hospitalization, this deterioration coincided with a SARS-CoV-2 infection. Management was escalated to therapeutic plasma exchange and cyclophosphamide. This regimen stabilized renal and hematological parameters, although severe neurological deficits and thrombocytopenia persisted. This case highlights that stroke may be a catastrophic presenting feature of AAV and that concurrent autoimmune cytopenias may add substantial diagnostic and therapeutic complexity. Early ANCA testing in cryptogenic or progressive stroke with systemic involvement is vital, and management requires careful balance between immunosuppression and infection risk.}, }

This review presents the opinion that the most critical recent developments are not that these proteins are toxic, but how their mechanisms converge. We synthesize evidence from the last two years showing that proteins from diverse, highly infectious virus families with zoonotic potential (e.g. Coronaviridae, Flaviviridae, Orthomyxoviridae) engage shared host pathways. We focus on two convergent mechanisms: (1) the activation of glial Toll-like receptor (TLR)4/TLR2 signaling, which initiates a chronic neuroinflammatory cascade, and (2) the disruption of host proteostasis, which seeds neurodegenerative proteinopathies like alpha-synuclein and tau aggregation. This framework positions post-viral syndromes as mechanistically related disorders and identifies pan-viral therapeutic targets, such as TLR inhibitors and autophagy activators.}, }

We performed statistical analyses using RevMan 5.4, employing the random-effects model, along with Risk Ratio (RR) and Mean Difference (MD) as the effect measures. Our meta-analysis of four RCTs showed that metformin did not significantly reduce the composite outcome of hospitalisation, emergency department (ED) visits, or death, compared with placebo (RR 0.60, 95% CI 0.40-0.90.21). The incidence of all-cause mortality (RR 1.00; 95% CI 0.06-15.91) and serious adverse events (RR 2.86; 95% CI 0.76-10.76) was also comparable between the two groups.

Lyophilization remains a cornerstone technology for enhancing the stability of these formulations; however, the freezing and drying processes impose major stresses that can compromise the integrity of fragile LNPs. This review systematically explores the molecular mechanisms by which lyoprotectants, including sugars, polyols, amino acids, and polymers, mitigate challenges such as ice-induced denaturation, dehydration-driven aggregation, and interfacial destabilization. This review emphasizes the importance of optimized sucrose-trehalose combinations and effective ice-nucleation control in preserving encapsulation efficiency and maintaining particle integrity. Furthermore, the review discusses advanced process optimization tools, including digital twin modeling and in-line Raman spectroscopy, which enhance lyophilization efficiency by reducing primary drying times by up to 40% while ensuring critical quality attributes are preserved. Additionally, emerging applications utilizing novel excipient combinations are highlighted, showcasing their potential to enable refrigerated storage of viral vectors. With 85% of commercial conjugates relying on lyophilization, recent advancements in continuous freeze-drying technology, such as spin-freeze approaches, have achieved cycle times that are three-fold faster. These developments provide a comprehensive roadmap for overcoming cold chain limitations while addressing the stabilization needs of next-generation biologicals, CRISPR-based systems, and personalized medicines.}, }

Despite its high acceptance rate among dental professionals, the perspectives of patients and the public remain less explored. This narrative review synthesizes evidence on public perception, acceptance, utilization, and satisfaction of teledentistry globally.<br><br>METHODS: A comprehensive search was conducted across PubMed, Scopus, EMBASE, Web of Science, Cochrane Database, and Google Scholar for peer-reviewed English articles (2010-2025) using keywords like "teledentistry," "patients," and "public." Included studies assessed patient and public perspectives on teledentistry benefits, barriers, satisfaction, and utilization. Exclusions comprised non-patient or non-English articles. Data from 21 selected studies were narratively synthesized.<br><br>RESULTS: Awareness of teledentistry varied widely (e.g., 64% aware in one Saudi Arabian study vs. 87.3% unaware of teledentistry in a study in Jeddah). Attitudes were generally positive, as seen with 82.4% of the cohort in a Malaysian study, where the convenience of tele-orthodontics and increased safety during COVID-19 were observed, although older adults across the studies and those with lower levels of education reported technological barriers. Acceptance rates of teledentistry were high among patients (70%-87% in Saudi Arabia, the United Kingdom, and Malaysia), particularly when used for triage and follow-ups, but lower for complex treatments (e.g., 35.3% of patients in a Qatar study noted unresolved issues following teledentistry consultations, like pulpitis). Satisfaction was favorable across the cohorts (reaching between 72% and 94% across multiple studies) due to the benefits of reduced treatment time and lower financial cost; however, patient satisfaction declined when they faced dental conditions requiring physical intervention. Key barriers faced by patients and the public to teledentistry included limited awareness, patient concerns with diagnostic accuracy, and technical access issues.<br><br>CONCLUSION: Public perception of teledentistry is moderate, attitudes are broadly positive, and teledentistry is being increasingly accepted with high satisfaction rates for convenient, non-urgent care. However, demographic factors, such as age, education, and location, and clinical limitations for hands-on treatments limit its utilization. Teledentistry is best positioned as a complement to traditional care through hybrid models. Future efforts should prioritize targeted education, improved accessibility, and standardized teledentistry protocols to optimize equitable implementation.}, }

It is currently the most widely used selective SphK2 inhibitor. It simultaneously inhibits three sphingolipid-metabolizing enzymes in human cells-SphK2, dihydroceramide desaturase (DES1), and glucosylceramide synthase (GCS)-leading to depletion of sphingosine 1-phosphate (S1P), accumulation of ceramides and dihydroceramides, and suppression of key pro-survival pathways including pERK, pAKT, and NF-κB.

Since the widespread rollout of SARS-CoV-2 vaccines, several cases of CLs and non-neoplastic lymphoproliferative disorders (nn-LPDs) temporally associated with vaccination have been reported, raising concerns about a potential immunologic link.<br><br>OBJECTIVE: To systematically review the literature on cases of CLs and related nn-LPDs occurring after COVID-19 vaccination, focusing on clinical features, subtype distribution, latency to onset, and proposed pathophysiological mechanisms.<br><br>METHODS: A systematic review was conducted according to PRISMA guidelines. Case reports and series describing new-onset or relapsed CLs or nn-LPDs temporally following SARS-CoV-2 vaccination were included. Demographic, clinical, histological, therapeutic and temporal data were extracted and analysed.<br><br>RESULTS: Fifteen manuscripts encompassing 35 cases met the inclusion criteria. Eighteen (51.4%) were histologically confirmed CLs, most commonly lymphomatoid papulosis (n&#x2009;=&#x2009;9), followed by S&#xe9;zary syndrome (n&#x2009;=&#x2009;3) and mycosis fungoides (n&#x2009;=&#x2009;2). The remaining 17 cases (48.6%) were classified as nn-LPDs, including cutaneous lymphoid hyperplasia, lymphomatoid reactions and CD4+ small/medium T-cell lymphoproliferative disorders. CD30 positivity was noted in 76.2% of the cases with available immunophenotyping. Most patients (80%) received the BNT162b2 (Pfizer-BioNTech) vaccine. In the 17 new-onset CLs, time to onset ranged from 3 to 42&#x2009;days, with most cases clustering within 14&#x2009;days.<br><br>CONCLUSIONS: Most of the cases were low-grade T-cell CLs and nn-LPDs. Although a causal relationship cannot be established, the short latency observed in many new-onset cases raises the possibility that some patients may have harboured an undiagnosed disease, with vaccination acting as a trigger for clinical manifestation or for raised awareness. These findings support indeed the need for continued pharmacovigilance among clinicians, especially in patients with prior or latent lymphoproliferative conditions. Nevertheless, these extremely rare and indolent events should not alter the overall favourable risk-benefit profile of COVID-19 vaccination.}, }

This review aims to address this gap by systematically analyzing the diagnostic and prognostic potential of these neglected biomarkers, with particular emphasis on their mechanistic connections to COVID-19 pathophysiology. Reduced levels of adiponectin and prostacyclin (PGI2) and elevated level of endothelin are associated with endothelial dysfunction, whereas elevated levels of endocan and endoglin are indicative of elevated vascular inflammation. Increased concentrations of markers such as angiopoietin, E-selectin, P-selectin, ICAM-1, and VCAM-1 suggest endothelial activation, while higher levels of fractalkine, galectin, HMGB1, and osteopontin reflect an ongoing inflammatory state. Immunological markers, including HMGB1, neopterin, and serum amyloid A, are significantly elevated, underscoring prolonged immune activation associated with severe COVID-19. Elevated levels of matrix metalloproteinases (MMPs) and soluble urokinase plasminogen activator receptor (SuPAR) highlight tissue remodeling and fibrinolytic imbalance related to vascular injury. Additionally, increases in soluble fms-like tyrosine kinase-1 (sFlt-1) and pentraxin reflect inflammatory pathways that exacerbate endothelial dysfunction. Elevated levels of syndecan-1 reflect endothelial glycocalyx degradation and impaired endothelial barrier integrity. Increased von Willebrand factor (vWF) indicates endothelial activation and injury with a prothrombotic shift. Elevated surfactant protein D (SP-D) is a marker of pulmonary epithelial injury and disruption of the alveolar-capillary interface. Other biomarkers, such as the receptor for advanced glycation end products (RAGE) and MR-proADM, signal oxidative stress and endothelial damage. Collectively, these biomarkers emphasize the extensive vascular and endothelial impairment in COVID-19, suggesting their utility as diagnostic tools and potential targets for therapeutic intervention against the systemic effects of the disease. This review advocates for the integration of these biomarkers into standard monitoring and treatment protocols for COVID-19, thereby enhancing personalized care. Furthermore, our analysis underscores the necessity for additional research into the roles of these biomarkers in other endothelial disorders, ultimately contributing to a more nuanced approach to managing viral infections characterized by vascular complications.}, }

While most comorbidities are difficult to modify in the acute setting, anemia, particularly iron-defi ciency anemia, represents a potentially modifiable risk factor. Clinicians are also often confronted with complex alterations in hemostasis that require rapid assessment and targeted therapeutic interventions, including the optimal use of blood products. This narrative review summarizes the current evidence on Patient Blood Management strategies, including anemia management, the use of small-volume tubes, and the appropriate use of blood products in intensive care unit patients.<br><br>RESULTS: Intravenous iron supplementation can safely raise hemoglobin to a clinically meaningful degree. Erythropoietin therapy may also raise hemoglobin, but its use should remain selective given uncertain thromboembolic risk. Small-volume blood collection tubes and closed blood-conservation systems should be routinely used to reduce iatrogenic anemia. Current evidence supports restrictive red blood cell transfusion strategies in most clinical settings, particularly in patients with gastrointestinal bleeding. Similarly, a restrictive platelet transfusion strategy is supported by current evidence. Prophylactic platelet transfusion should be reserved for high-risk hematologic malignancies. In other critically ill patients with severe thrombocytopenia, a therapeutic (bleeding-driven) approach is preferred. Finally, current evidence does not support prophylactic fresh frozen plasma transfusion in non-bleeding patients.<br><br>CONCLUSIONS: Overall, these findings support the implementation of Patient Blood Management strategies that optimize blood health and promote safer, more individualized care in critically ill patients.}, }

Predefined data items (bibliographic details, epidemic and RL model characteristics, experiments, validation methods, outcomes) were charted and summarized descriptively.<br><br>RESULTS: Of 512 retrieved records, 10 met the inclusion criteria, and three additional studies were identified via reference-list scanning, yielding 13. Five employed value&#x2011;based methods, four policy&#x2011;gradient, and four hybrid; one study additionally incorporated model-based planning. Six simulations relied on compartmental models, six on agent&#x2011;based models, and one on a hybrid model. Action spaces were predominantly discrete restriction levels. Five studies incorporated sequence-modeling techniques to include temporal context into a state space. Eleven studies designed reward functions as a trade-off between pandemic severity and socio-economic cost. According to the reviewed studies, RL policies across various settings outperform heuristic, rule-based, and historical baselines in reducing infections, deaths, or lockdown duration while limiting economic loss.<br><br>CONCLUSIONS: RL shows promise for adaptive epidemic control. Comparison is hampered by simplified economic costs, inconsistent calibration rigor, varied evaluation metrics, and limited uncertainty or policy robustness analysis. Future work should establish common benchmark environments and reporting standards, incorporate empirically grounded economic and behavioral models, adopt uncertainty-aware and probabilistic RL, develop more sophisticated control spaces, investigate more advanced algorithms, and validate learned policies prospectively to enable real-world deployment.}, }

The 5' region comprises an open reading frame (ORF1a) that encodes the polyprotein pp1a and, through a programmed frameshifting event, enables the production of the extended polyprotein pp1ab. These polyproteins are processed by the viral proteases 3CLpro and PLpro into 16 nonstructural proteins (nsps). Nsps 1-11 participate in polyprotein processing, formation, and regulation of the replication-transcription complex, and modulation of host immune responses. Nsps 12-16 form the core of the viral RNA synthesis machinery and are primarily associated with RNA-dependent RNA polymerase activity, proofreading, capping, and RNA modification, while also functioning in coordination with additional nsps. The 3' functional region of the genome encodes structural (S, E, M, and N) and accessory proteins (e.g., 3a, 6, 7a, 8, and 9b) that contribute to viral assembly, replication efficiency, and pathogenicity. Synthesis of pp1ab depends on a programmed -1 ribosomal frameshifting (-1 PRF) event mediated by cis-acting RNA elements that induce a one-nucleotide shift in the 5' direction of the ribosome. This mechanism is critical for maintaining the stoichiometric balance of replication proteins. Here, we review recent current insights into the molecular mechanisms and structural dynamics of -1 PRF in SARS-CoV-2 and discuss its potential as a therapeutic target for antiviral intervention across clinically relevant coronaviruses.}, }

Major cardiotropic and cardioactive viruses-including severe acute respiratory syndrome coronavirus 2, influenza virus, human immunodeficiency virus, arboviruses (dengue virus, chikungunya virus, Zika virus), enteroviruses (coxsackievirus B3), and human cytomegalovirus-contribute to myocardial injury manifesting as myocarditis, pericarditis, arrhythmias, acute and chronic heart failure, and thromboembolic complications. Mechanisms of cardiac involvement are multifactorial, involving direct infection of cardiac cells leading to cytopathic effects and innate immune activation, dysregulated adaptive immune responses promoting myocardial inflammation and fibrosis, electrophysiological disturbances, and systemic effects such as endothelial dysfunction and prothrombotic states that precipitate ischemic events. Clinical manifestations range from subclinical injury to fulminant myocardial inflammation and may also include long-term sequelae, such as post-acute cardiovascular symptoms, as observed in long COVID cases. Therapeutic strategies emphasize early antiviral treatment when effective agents exist, judicious immunomodulation based on viral replication status, and supportive management of cardiac dysfunction and arrhythmias. Prevention through vaccination, personal protective measures, vector control, and optimization of cardiovascular risk factors remains pivotal to reduce the burden of virus-associated cardiovascular diseases. Future research requires improved diagnostic precision, mechanistic elucidation, and randomized trials to optimize antiviral and immunomodulatory interventions and to develop vaccines for currently unmet viral targets. An integrated, mechanism-informed approach across prevention, acute management, and long-term care is essential to mitigate the cardiovascular morbidity and mortality attributable to viral infections.}, }

Conversely, misfolded or aggregated α-syn represents a hallmark of synucleinopathies, including Parkinson's disease. Beyond the nervous system, α-syn has been detected in peripheral compartments, including blood cells and selected epithelial tissues, although the robustness and context dependence of expression outside neuronal and erythroid lineages remain under active investigation. Also, it can be released extracellularly through unconventional secretion or cell damage. These observations have reframed α-syn as an immune-relevant molecule positioned at host-pathogen interfaces, endowed with antimicrobial peptide-like and damage-associated molecular pattern-like properties that enable shaping of both innate and adaptive immunity. Increasing evidence indicates that viral challenge alters α-syn expression, localization, and conformational states in central and peripheral settings, in part through interferon-dependent programs that couple antiviral immunity with cellular homeostasis. A plethora of RNA viruses, such as influenza virus, flavivirus, enterovirus, and coronavirus, perturb α-syn abundance, post-translational modifications, trafficking, secretion, and aggregation propensity. These effects converge on shared mechanisms that include altered proteostasis, autophagy-lysosomal dysfunction, oxidative and mitochondrial injury, and inflammatory signaling. Importantly, outcomes are highly context dependent, ranging from cell-intrinsic antiviral restriction to aggregation-prone states that may fuel chronic inflammation and neurodegeneration. Collectively, the evidence discussed herein supports a dual framework in which α-syn contributes to antiviral defense; yet, under conditions of sustained inflammation or impaired clearance, it may undergo pathological transformation that promotes neuronal damage. Defining when virus-induced α-syn responses are protective versus pathogenic, and clarifying their relevance to human disease, will be critical for developing strategies that target host-virus interactions, neuroinflammation, and α-syn proteostasis in infection-associated synucleinopathies.}, }

Passive immunization represents an encouraging approach, with immunoglobulin Y (IgY) derived from hyperimmunized hen egg yolk emerging as a promising, cost-effective, and ethical alternative to conventional mammalian-derived antibodies. IgY technology addresses challenges including stability, process complexity, and antimicrobial resistance, offering practical advantages for human and animal applications.

Evidence from the IgY literature is broadly encouraging, demonstrating efficacy in pathogen neutralization, virulence attenuation, and hypersensitivity suppression, particularly through intranasal and oral delivery routes. IgY technology represents an affordable and scalable tool for low- and middle-income countries (LMICs) and beyond. Future priorities should include standardized antibody production protocols, optimized formulations and dosing strategies, rational point-of-care diagnostic integration, and well-designed prospective trials in high-burden settings to bring forth IgY technology's translational potential against prevailing and forthcoming respiratory afflictions.}, }

Beyond traditional genome-editing capabilities, newly engineered versions of CRISPR/Cas can be used for programmable transcriptional regulation, epigenetic modification, molecular imaging, and ultrasensitive nucleic acid detection. Specifically, catalytic-inactive Cas proteins like dCas9 and dCas12 retain their ability to bind specific sequences on DNA but do not cleave it. Therefore, these proteins can be reversibly regulated by either CRISPRi or CRISPRa to alter gene expression. Thus, they represent powerful tools for both functional genomic studies and synthetic biological applications. Advances in CRISPR engineering have recently greatly increased the diagnostic potential of Cas12 and Cas13 enzymes. For example, collateral cleavage activity allowed the creation of CRISPR-based diagnostic platforms (SHERLOCK, DETECTR and FELUDA), which can detect target DNA/RNA sequences at high sensitivity and specificity. Moreover, they were demonstrated to work in detecting several infectious pathogens (SARS-CoV-2, Zika virus, and M. tuberculosis) and thus have significant value in point-of-care testing, especially when there is limited availability of resources. CRISPR systems are also being combined with increasing frequency with epigenetic regulators, fluorescence microscopy methods, biosensors, and lab-on-a-chip platforms that incorporate microfluidics to provide improved molecular analysis and automated diagnosis. The purpose of this review is to describe how engineered CRISPR-Cas systems have been developed from primarily genome editing tools into multi-functional platforms for transcriptional regulation, epigenetic engineering, diagnostics, imaging, and emerging microfluidic integrations. Additionally, this review will address some of the current challenges that exist with using CRISPR-based technologies, including off-target effects, delivery efficiency, diagnostic standardization, scaling up production, and translating these technologies clinically.}, }

The available evidence suggests that DFPC can improve convenience, flexibility, and timeliness of first contact for some patients, but these gains are unevenly distributed and depend heavily on system design, workflow integration, and patient capability. Evidence generated during the COVID-19 emergency should not be conflated with the evaluation of routine, policy-driven post-pandemic DFPC, because the goals, constraints, and patient expectations differ across these contexts. We therefore argue that DFPC aligns with PCC only when implemented within a flexible hybrid model that preserves modality choice, supports continuity, provides safe escalation to in-person care, and actively mitigates digital exclusion. Future research should prioritize patient-reported experience, continuity, safety, and equity outcomes under routine post-pandemic conditions.}, }

Studies were systematically selected based on predefined eligibility criteria, and 24 studies examining individual and work-related factors associated with work productivity loss were included. Risk of bias was assessed using the Joanna Briggs Institute critical appraisal tools. Correlation coefficients were synthesized using a random-effects meta-analysis of correlations in STATA 17.0, and heterogeneity was evaluated using the I[2] statistic and Cochran's Q test. Findings: Twenty-one factors were analyzed. Job stress, fear of COVID-19, mental health problems, job insecurity, turnover intention, exhaustion, and job demands exhibited moderate positive correlations with productivity loss during the COVID-19 pandemic. Fear of COVID-19 and mental health problems showed relatively large positive correlations with presenteeism. General health status was the factor most strongly associated with absenteeism, exhibiting a moderate negative correlation.

In terms of antibacterial effects, SCFAs exhibit antibacterial activity against most gut microorganisms, but they support the colonization of a few species (i.e., Campylobacter jejuni). Given the complex interactions between SCFAs and the gut microbiota, as well as their regulatory roles in infection, further investigation of the microbiota-SCFA axis is essential for developing effective strategies to prevent and treat infectious diseases.

Several host factors have been identified as high confidence substrates of 3CL[Pro] which regulates host cellular environment both in an enzyme-dependent and enzyme-independent manner. Degradation of RIG-I, TRIM25 and NLRP12 by 3CL[Pro] downregulates the innate immune response while enzyme-independent interaction with host factors like MAVS promote both its degradation and upregulation. Cellular transcription and translation are altered by interaction of 3CL[Pro] with host proteins. It affects cell-death by interacting with factors like Gal-8, NDP52 and GSDMD. Post-COVID neurodegenerative disorders have been observed due to the downregulation of neuronal factors like NEMO and UBE3A. The spectrum of 3CL[Pro] interaction with the key host factors indicates the alternate role of viral protease that modulates host response during infection.

Primary outcomes included clinical symptoms (Borg score, dyspnea) and physical function (30-s sit-to-stand test, 6-min walking distance). A random-effects model assessed pooled outcomes with heterogeneity (I[2]) and sensitivity analyses along with subgroup analysis. Additionally, publication bias and certainty of evidence using Gradepro was performed. Risk of bias was evaluated using the Cochrane ROB2 tool.<br><br>RESULTS: Twenty-eight randomized controlled trials (RCT's) comprising approximately 1,400 participants were included. TR significantly improved physical function, including the 30&#xa0;s-STS (MD&#x2009;=&#x2009;2.07; 95% CI: 1.24 to 2.90; p&#x2009;<&#x2009;0.00001) and 6MWD (MD&#x2009;=&#x2009;85.83&#xa0;m; 95% CI: 67.14 to 104.52; p&#x2009;<&#x2009;0.00001). Significant reductions were observed in dyspnea (Borg overall MD&#x2009;=&#x2009;-3.74, p&#x2009;=&#x2009;0.003) and fatigue (VASF MD&#x2009;=&#x2009;-1.83, p&#x2009;<&#x2009;0.0001). However, no significant differences were found for HADS-Anxiety (p&#x2009;=&#x2009;0.27) or HADS-Depression (p&#x2009;=&#x2009;0.11). Pulmonary function showed significant gains only in FEV1 change scores (p&#x2009;=&#x2009;0.008). Preliminary data suggests a favorable safety profile; while no serious adverse events were reported across the trials, safety was infrequently listed as a primary outcome.<br><br>CONCLUSION: TR appears to be a promising and well-tolerated modality for enhancing physical capacity and alleviating fatigue in post-COVID-19 patients, though further large-scale studies with safety as a primary endpoint are warranted to definitively establish its safety profile. While physical gains are robust, additional targeted interventions may be necessary to address psychological and pulmonary sequelae.}, }

Electronic databases (PubMed, Embase, CINAHL, Scopus, and Web of Science) were searched from inception to 17 March 2026. Observational studies reporting long-term outcomes of infection-associated urticaria following viral infection were included. Data extraction and risk of bias assessment using the Newcastle-Ottawa Scale were performed independently by two reviewers. Due to substantial heterogeneity, findings were synthesized narratively.<br><br>RESULTS: Five studies involving 596 participants were included. Most cases of infection-associated urticaria occurred during the acute phase of infection and resolved within weeks to months. However, persistence beyond 6 months was reported in up to 9.5% of cases, and a small proportion demonstrated persistent symptoms extending beyond 1 year. Reported recurrence and chronicity rates ranged from approximately 7% to 30%, although several estimates were derived from mixed-etiology cohorts in which infection-related cases were not analyzed separately. Delayed-onset urticaria, particularly following SARS-CoV-2 infection, was associated with an increased likelihood of progression to chronic spontaneous urticaria. However, interpretation is limited by the inclusion of mixed-etiology cohorts in which viral infection was not always laboratory-confirmed or analyzed separately.<br><br>CONCLUSION: Infection-associated urticaria is typically self-limiting; however, a small but potentially clinically relevant subset of patients may develop persistent or chronic symptoms. Recognition of potential risk patterns, particularly delayed-onset urticaria in the context of SARS-CoV-2 infection, may support improved patient counselling and follow-up.

The demand for high-affinity antibodies continues to surge, yet traditional discovery platforms such as hybridoma and phage display suffer from low efficiency, disrupted native pairing, and time-consuming workflows. Single B cell antibody technology overcomes these limitations by directly retrieving naturally paired heavy and light chain sequences from antigen-specific B cells, thereby preserving authentic affinity and specificity. Following its remarkable success in combating human emergencies like COVID-19, this platform is now being rapidly adapted to veterinary viral diseases, a critical effort under the "One Health" framework to safeguard both animal and public health. This review systematically outlines the core principles and workflows of single B cell-based mAb discovery. It then summarizes recent advances in applying this technology to viruses that infect animals and zoonotic viruses, emphasizing how native antibody repertoires have been harnessed to generate high-affinity mAbs. Ultimately, the article concludes with a discussion of current technical challenges, proposing future research directions to improve both the accessibility and efficacy of veterinary immunotherapeutics.}, }

Pregnant individuals may be uniquely susceptible to post-viral fatigue due to immunological and physiological adaptations during gestation. This review consolidates existing data regarding the prevalence, risk factors, and clinical implications of Long COVID-associated fatigue in pregnant individuals. A narrative review was conducted of studies examining fatigue among pregnant individuals with confirmed SARS-CoV-2 infection. Key outcomes included fatigue prevalence, symptom persistence, associated risk or protective factors, and comparisons with non-pregnant populations. Across both the acute and post-acute stages of COVID-19, fatigue emerged as a consistently common symptom. Its prevalence and persistence varied significantly across studies, partly due to heterogeneity in assessment tools and follow-up durations. Severe acute illness, hospitalization, obesity, and smoking during pregnancy were linked to a higher risk of prolonged fatigue, whereas anosmia appeared to act as a potential protective factor. In contrast, comorbidities such as hypertension, diabetes, and lung disease were not significantly linked to fatigue risk. No consistent associations were found with maternal age or alcohol use. Long COVID-related fatigue presents a substantial burden in pregnancy, with implications for maternal health, quality of life, and postpartum recovery. Early recognition, individualized care strategies, and public health interventions targeting modifiable risk factors are essential to support this vulnerable population. Ongoing research is essential to uncover underlying mechanisms and guide evidence-based clinical management.}, }

Integrating routine mental health screening using validated tools such as the CES-D or PHQ-9 into oncology care is essential. Structured interventions including counseling, psych-education, and respite care should be embedded within care pathways.

While the legislative framework allows for the provision of these services in community pharmacies, the process is often complex. This article describes various models for the provision of HIV services in community pharmacies in South Africa through a review of existing policies and legislation. It further discusses barriers and opportunities for the expansion of services. The existing legal framework enables prescribing by healthcare professionals other than medical practitioners through authorisations issued under either the Medicines and Related Substances Act of 1965 or the Nursing Act of 2005. Community pharmacies have extended their role beyond dispensing medication, with the emergence of telehealth and potential initiatives such as Pharmacist-Initiated Management of Antiretroviral Therapy (PIMART). Telehealth, accelerated by the COVID-19 pandemic, provides remote consultations and electronic prescriptions. PIMART, on the other hand, can empower pharmacists to initiate and manage antiretroviral therapy (ART) for HIV patients, a role traditionally reserved for clinicians. Extending Nurse-Initiated Management of Antiretroviral Therapy (NIMART) into the private sector could further increase ART rollout. Despite these advancements made in the last two decades, legislative reforms are necessary to fully realise the potential of community pharmacies for providing HIV services.}, }

Traditional surveillance systems, while foundational to public health, are increasingly limited by delayed reporting, data silos, and fragmented information flows. In response to these limitations, the integration of AI and big data offers new possibilities for enhancing disease detection, monitoring, and response strategies on both local and global scales. This review explores the potential of AI-enabled tools and big data systems to support early outbreak detection, real-time surveillance, and predictive modeling. These technologies facilitate the synthesis of diverse datasets, including clinical, genomic, geospatial, and environmental information, enabling a more holistic understanding of disease patterns. Additionally, AI contributes to improved diagnostic accuracy and optimized resource allocation, which are critical during public health emergencies. However, the adoption of these technologies has not been without challenges. Concerns about data privacy, equity in access, algorithmic bias, and over-reliance on automated systems present significant ethical and operational hurdles. In low-resource settings, limited digital infrastructure further complicates implementation. The review also highlights real-world applications from recent outbreaks, such as COVID-19, influenza, and Zika, to demonstrate both the promise and the limitations of AI-driven surveillance. To move forward responsibly, public health systems must adopt a balanced approach that integrates AI capabilities with human oversight. Strategic investment, cross-sector collaboration, and the development of clear ethical frameworks are essential to unlocking the full potential of big data and AI in infectious disease surveillance.}, }

However, newly emerging species, some exhibiting antifungal resistance, are becoming increasingly common. IA mainly affects immunocompromised individuals, including those with hematological malignancies and solid organ transplant recipients. In recent years, however, new at-risk populations have been identified, regardless of immune status, particularly those with severe viral infections requiring intensive care unit admission. This condition has gained prominence in intensive care unit settings following the recent H1N1 influenza and COVID-19 pandemics. Virus-associated pulmonary Aspergillosis (VAPA) encompasses two distinct entities: influenza-associated pulmonary Aspergillosis (IAPA) and COVID-19-associated pulmonary Aspergillosis (CAPA). These conditions are typically diagnosed in 10-20% of patients with severe influenza or COVID-19 when appropriate diagnostic methods are employed. Key diagnostic tools include bronchoalveolar lavage for fungal culture, galactomannan testing, and Aspergillus PCR, complemented by bronchoscopy to detect invasive Aspergillus tracheobronchitis visually. Azole antifungals are the first-line treatment, with liposomal amphotericin B serving as an alternative in regions with azole resistance. Despite antifungal interventions, IAPA and CAPA are linked to poor outcomes, with fatality rates often surpassing 50%. This review article discusses the pathophysiological mechanisms, clinical characteristics, diagnosis, and treatment of IAPA and CAPA.

The search followed guidance from the Joanna Briggs Institute on conducting systematic scoping reviews, and our reporting is in line with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines for scoping reviews. We included both academic and gray literature in the English language. As this is an emerging field, an additional step involved input from an informal expert group to identify any further tools or approaches. Studies that assessed, described, or discussed approaches to assessing the information environment were included. We excluded papers where the information environment was not the primary focus, or the focus was on individual components only. Two authors (BKW and SVM) independently screened results for inclusion.<br><br>RESULTS: A total of 17 publications were identified through the structured literature and internet searches, with an additional 5 sourced from the informal expert group. The review highlighted a significant variety in the breadth and number of domains covered in an assessment, including information needs, seeking, access, production, engagement, information quality, and reach. Some assessments adopted a comprehensive, systems-oriented approach, examining factors influencing information beyond the individual level to encompass broader systemic dynamics, while others were significantly narrower in scope.<br><br>CONCLUSIONS: The COVID-19 pandemic has intensified interest in understanding how the information environment shapes people's access to, engagement with, and ability to act on health information.

Such infections may affect a range of ocular tissues through mechanisms including direct viral invasion, immune-mediated inflammation, and secondary complications. While the frequency and severity of ocular involvement vary among pathogens, the potential for permanent vision loss, particularly in unvaccinated or immunocompromised individuals, underscores the clinical and public health importance of early recognition and prevention. Conditions such as congenital rubella syndrome, herpes zoster ophthalmicus, and acute retinal necrosis illustrate the breadth of pathology, while emerging infections like COVID-19 and monkeypox further expand the spectrum. Vaccination remains the most effective strategy for mitigating both systemic and ophthalmic sequelae. Greater awareness of ocular manifestations can facilitate earlier diagnosis, enhance outbreak detection, and reinforce the critical role of immunization in preserving vision.}, }

In healthy young individuals, these elements are kept dormant by robust epigenetic mechanisms, primarily DNA methylation and repressive H3K9me3 histone marks. However, this epigenetic silencing deteriorates with age, leading to the reactivation of HERVs, particularly the youngest HERV-K subfamily. This report posits that this HERV awakening is not a passive byproduct of aging but an active, transmissible driver of pathology. The reactivation of HERVs leads to the production of retrovirus-like particles (RVLPs) that can induce senescence in healthy neighboring cells, propagating a contagious aging phenomenon. Furthermore, the accumulation of HERV-derived dsRNA and reverse-transcribed DNA triggers chronic innate immune responses through pathways including cGAS-STING and IFIH1-MAVS, fueling the systemic, low-grade inflammation characteristic of inflammaging, catalytically accelerated by exogenous viral infections. Pathogens such as SARS-CoV-2, Epstein-Barr Virus (EBV), and Herpes Simplex Virus (HSV-1) can directly transactivate HERVs via their own viral proteins, overwhelming the already compromised epigenetic controls in an aging host. This mechanistic link between viral triggers and endogenous retroviral activity is strongly implicated in a range of age-related diseases, including neurodegenerative disorders such as Alzheimer's disease and Amyotrophic Lateral Sclerosis (ALS), where the HERV-K envelope protein is directly neurotoxic. It is also linked to autoimmune diseases like Multiple Sclerosis and various cancers. This report synthesizes these findings and identifies a novel mechanistic link between viral activity, chronic inflammation, and the onset of age-related diseases.}, }

The highest incidence rates persist in low- and middle-income countries, where socioeconomic determinants such as poverty, malnutrition, overcrowded living conditions, and limited access to quality healthcare exacerbate disease transmission and worsen outcomes. The emergence and spread of drug-resistant TB, including multidrug-resistant (MDR-TB), extensively drug-resistant (XDR-TB), and totally drug-resistant (TDR-TB) strains, pose significant challenges to effective treatment and control, contributing to increased mortality and healthcare costs. The coronavirus disease-2019 (COVID-19) pandemic has further disrupted TB services worldwide, causing declines in case detection, delayed diagnoses, and interruptions in treatment, thereby reversing years of progress. Despite the availability of effective vaccines and treatment regimens, gaps in awareness, funding, healthcare infrastructure, and social determinants of health hinder global elimination efforts.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection disrupts redox homeostasis through excessive generation of reactive oxygen and nitrogen species, driving inflammation, endothelial dysfunction, and multi-organ injury. Serum oxidative and antioxidative enzymes, their genetic polymorphisms, and essential micronutrient cofactors have emerged as potential prognostic biomarkers for COVID-19 severity and mortality. Evidence indicates that imbalances in antioxidant enzymes such as superoxide dismutase, catalase, glutathione peroxidase, and glutathione reductase correlate with disease progression, while polymorphisms in GST, superoxide dismutase, CAT, and HO-1 genes may modify susceptibility and outcomes. Biomarkers of oxidative damage, including malondialdehyde, 8-isoprostanes, nitrotyrosine, and protein carbonyls, consistently associate with respiratory failure, intensive care admission, and mortality. Furthermore, micronutrients such as selenium, zinc, copper, manganese, and iron, which act as enzymatic cofactors, influence antioxidant defense capacity and clinical prognosis. Despite promising data, limitations in biomarker standardization and assay specificity remain key challenges for clinical translation. The aim of this systematic review is to integrate enzymatic, genetic, and cofactor-based biomarkers to enhance risk stratification, challenging and to improve prognostic modelling in COVID-19. A better understanding of these biomarkers may facilitate early identification of high-risk patients, guide therapeutic interventions, and ultimately improve clinical outcomes in COVID-19.}, }

However, the growing demand for postoperative rehabilitation has intensified the strain on the physical therapy (PT) workforce. The COVID-19 pandemic accelerated the adoption of telerehabilitation, but evidence regarding its effectiveness, safety, cost-efficiency, and equity after TKA remains scattered. A narrative review of English-language, full-text articles published between January 2018 and May 2025 was performed. PubMed, MEDLINE, and Google Scholar were searched using terms including "telerehabilitation", "virtual physical therapy", and "total knee arthroplasty". Eligible studies were randomized controlled trials (RCTs), cohort studies, case series (n ≥ 10), or systematic reviews/meta-analyses that compared telerehabilitation with conventional in-person rehabilitation after TKA. Outcomes included functional metrics, e.g., Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Oxford Knee Score (OKS), Knee Injury and Osteoarthritis Outcome Score (KOOS), and Knee Society Score (KSS), pain (visual analog scale, VAS), patient satisfaction, adherence, cost/utilization data, and equity indicators. Eight studies (six RCTs, two meta-analyses; n ≈ 2,070) met the inclusion criteria. Interventions included AI-driven apps, video-based therapy, and wearable sensors. Most studies found telerehabilitation to be non-inferior to conventional PT in improving pain, range of motion (ROM), and function. Meta-analyses showed comparable gains in KOOS, ROM, and VAS scores. Cost-effectiveness was favorable in bundled care models, though technology costs were inconsistently reported. No increased adverse events were observed. Digital literacy and broadband access emerged as equity challenges. Telerehabilitation is a safe, effective adjunct to in-person PT following TKA, with potential to expand access and reduce system strain. Hybrid models may offer the most sustainable path forward.}, }

In recent years, increasing evidence has supported the notion that certain viral infections – particularly herpesviruses, the human immunodeficiency virus (HIV), and SARS-CoV-2 – may contribute to neurodegenerative processes either directly or indirectly. It has been demonstrated that chronic inflammation, immune system dysregulation, and blood–brain barrier damage induced by viral agents potentially promote the pathogenesis of dementia, especially Alzheimer’s disease. Simultaneously, remarkable new research has emerged highlighting the potential protective effects of vaccination. According to a study conducted by Stanford University and published in 2025, elderly adults vaccinated against herpes zoster (shingles) exhibited a significantly lower incidence of dementia over a 7-year follow-up period. Researchers identified a 20% relative risk reduction, particularly among women. Other studies have supported similar effects for vaccines against influenza, tetanus, and diphtheria. The aim of our publication was to summarize the causative role of viral infections in dementia and to present the inhibitory effects of vaccines, which likely extend beyond specific antiviral infection prevention. Furthermore, we sought to emphasize the clinical and public health significance of these findings, particularly for the elderly population with compromised immune systems.

Digital health intervention product design and deployment are both important in getting National Health Service trusts, healthcare professionals and patients to engage with a digital health intervention. Projects should work closely with all user groups. Lockdown and the unmet need of a new patient group encouraged those who might otherwise have been reluctant to try a digital health intervention. Many patients and clinics accepted this digital remote support, which helped patients feel cared for while reducing strain on health services. This may encourage acceptance of other digital health intervention, although medical record integration remains a deterrent to clinics.<br><br>FUTURE WORK: This research focused on the development, deployment and evaluation of a digitally enabled rehabilitation programme for long COVID.

It emerged during the pandemic, with patients typically presenting with thrombosis at uncommon sites, thrombocytopenia, and elevated D-dimer levels. VITT antibodies and heparin-dependent antibodies bind to distinct PF4 epitopes. Recently, VITT-like clinical, laboratory, and anti-PF4 antibody features have also been observed in patients with adenoviral infections. Only four pediatric cases of cerebral venous sinus thrombosis (CVST) have been reported.<br><br>CASE REPORT: The patient was a previously healthy 2-year-old girl with no history of heparin exposure or SARS-CoV-2 vaccination. She presented with fever and was diagnosed with adenovirus infection. The fever resolved by day 4, but by day 6 she became increasingly lethargic and experienced vomiting. On day 12, Laboratory data showed severe thrombocytopenia and elevated D-dimer levels. Computed tomography revealed CVST along with a secondary hemorrhage in the right temporal lobe. She underwent hematoma removal with external/internal decompression and was started on continuous intravenous unfractionated heparin, and she was switched to warfarin. The thrombus decreased, platelet count spontaneously increased. Platelet activation assays using acute-phase serum identified a PF4-dependent platelet-activating antibody.<br><br>CONCLUSION: We report a case of CVST in a 2-year-old girl following adenovirus infection. Unlike heparin-induced thrombocytopenia, where heparin exacerbates the condition, it is effective here by competitively inhibiting anti-PF4 antibody binding. In patients with prior adenovirus infection presenting with CVST and thrombocytopenia, anti-PF4 disorders should be considered.}, }

Studies were included if they assessed obstetric and neonatal outcomes following mRNA COVID-19 vaccination in pregnant women. Data were extracted and analyzed using a random-effects model to calculate pooled odds ratios (ORs) and 95 % confidence intervals (CIs). Fifteen studies met the inclusion criteria, encompassing 42,944 vaccinated and 183,733 unvaccinated pregnant women. mRNA vaccination was associated with a significant reduction in preterm delivery (OR 0.743, 95 % CI 0.607-0.911), fetal distress (OR 0.699, 95 % CI 0.546-0.893), neonatal congenital abnormalities (OR 0.712, 95 % CI 0.570-0.889), and NICU admissions (OR 0.718, 95 % CI 0.617-0.836). However, a slight increase in gestational diabetes risk was observed (OR 1.107, 95 % CI 1.054-1.162). mRNA COVID-19 vaccines are safe during pregnancy and associated with reduced risks of adverse obstetric and neonatal outcomes. An observed marginal increase in gestational diabetes risk underscores the need for continuous monitoring. These findings support the inclusion of pregnant women in vaccination campaigns and inform public health policies and clinical practices to improve maternal and neonatal health outcomes.}, }

The agenda was updated in 2017, but since then, important research has been conducted, and major changes have occurred to the global health landscape impacted mainly by the COVID-19 pandemic. Therefore, there is a need to assess advances in zoonotic influenza surveillance methods reported between 2017 and 2024 in order to highlight key achievements and identify remaining gaps that limit their broader implementation, hence informing an update of the research agenda. We conducted a comprehensive literature review of zoonotic influenza surveillance and monitoring, focusing on novel and enhanced methodologies reported globally between 2017 and 2024. A systematic analysis was performed following PRISMA guidelines on 7490 peer-reviewed manuscripts from 2017 to 2024 retrieved from PubMed, of which 164 records were included in this review. Analysis of the information collected indicated several advances and gaps at different levels of surveillance and unmet public health needs. Most countries do not have active and comprehensive surveillance programs for zoonotic influenza at the human-animal interface, which underestimates the true burden of zoonotic influenza diseases. The review concludes with a set of high-priority research recommendations focused on filling gaps in One Health data integration, validation, and field deployment of novel diagnostic technologies, wider adoption of noninvasive and environmental surveillance approaches, and stronger linkage of methodological innovations to risk assessment and policy action. In light of the recent upsurge in H5N1 activity and cross-species transmission, the WHO has convened multiple R&amp;D Blueprint consultations over the past year to prioritize research and development for H5N1 candidate vaccines, diagnostics, and pandemic preparedness. These ongoing initiatives underscore the critical importance of strengthening surveillance at the human-animal interface.}, }

Yet, challenges persist in achieving universal accessibility and utilization. Since the COVID-19 pandemic, shifts have emerged in HPV vaccine research, implementation strategies, and the determinants shaping uptake and delivery, particularly from a global equity perspective.<br><br>METHODS: This is a scoping review examining English-language, peer-reviewed articles published following the onset of the COVID-19 pandemic until the end of 2024. It focuses on the human papillomavirus (HPV) vaccine and factors influencing its uptake. Articles were retrieved from PubMed and Embase databases and screened for relevance using predefined search terms.<br><br>RESULTS: Out of 2755 articles, 349 were included. We identified that most peer-reviewed articles focus on interventions and implementation strategies more than acknowledging geopolitical affairs, gender specificity, religious and ethical dimensions, medical mistrust, or healthcare discrimination. Most of the articles were cross-sectional in nature and most were funded by the National Cancer Institute. Interestingly, we found no peer-reviewed articles on the intersectionality of Judaism and HPV vaccine uptake, with a limited number on Islamic, Christian, or other religious intersectionality. Articles addressing how low- and middle-income countries could be equipped to develop and manage their own vaccine programs and manufacturing were largely absent; instead, cost-effectiveness research focused primarily on the vaccine&#x2019;s ability to reduce disease burden.<br><br>CONCLUSION: Post-pandemic research on HPV vaccination indicates that levels of hesitancy and uptake have remained relatively stable. However, the literature highlights persistent inconsistencies in how the vaccine is prioritized across communities, healthcare professionals, and health systems. Messaging regarding its importance for cancer prevention remains fragmented, while cost barriers and the absence of the vaccine from many national immunization schedules continue to limit access. Notably, ethical, religious, and cultural considerations receive limited attention in current research, despite the pandemic underscoring the global significance of these factors in shaping health behaviors. These findings suggest a need to re-examine how HPV vaccination is framed and advanced as a public health priority within diverse sociocultural and systemic contexts.}, }

Whole-genome sequencing (WGS)-based genomic epidemiology allowed us to gain relevant insights into this upsurge as it was happening. This review integrates the canonical research publication-based approach with genomic data and metadata and identifies a subset of genomic clusters playing a major role in invasive GAS (iGAS) infections worldwide, which were named as Global Pathogenic Lineages (GPLs). The four GPLs broadly coincide with five sequence types (STs): GPL1 with ST28, GPL2 with ST15 and ST315, GPL3 with ST52, and GPL4 with ST39. While non-GPLs clusters maintain a baseline reservoir of antimicrobial-resistance and virulence genes, GPLs show varying but noteworthy resistance profiles and are frequent causes of iGAS. The integration of WGS into routine diagnostics procedures is a forthcoming improvement, aimed not only at informing tailored therapy and implementing infection control strategies, but also to perform continuous surveillance. Ongoing WGS in clinical microbiology, as a matter of fact, will provide unparalleled insights into lineage emergence, transmission dynamics, and the geographic clustering of virulence and resistance determinants.}, }

Our analysis revealed a degree of methodological uniformity as most were quantitative survey-based investigations conducted in Europe and the United States with trust typically operationalized through Likert-scale measures assessing attitudes toward science, scientists, public health authorities, and the vaccines themselves. Conceptual diversity was also evident as although trust was treated as a key explanatory factor in nearly all studies, its referents varied widely, from institutions and information sources to personal dispositions and social dynamics. Similarly, the implications of trust ranged from vaccination intention and motivation to hesitancy and actual uptake. The meta-narrative framework highlighted that attitudinal and contingent trust dominated the literature, while cognitive and affective dimensions were mainly underexplored. Despite the methodological dominance of quantitative approaches, this standardization offers strengths of comparability and policy relevance, but the limited exploration of emotional, relational, and communicative aspects of trust points to missed opportunities for more nuanced understanding.<br><br>CONCLUSION: The meta-narrative approach provided a valuable tool for synthesizing conceptual pluralism.

Their analysis identified three principles to guide the process of developing QLLs: 1) Creating a supportive climate; 2) Choosing the right leaders or facilitators for the process; and 3) Engaging in a scientific approach. Based on these findings, we developed a guide comprising 11 steps, structured into two main phases: preparatory steps for QLL development, and steps for identifying and formulating QLLs. This guide offers a structured process for teams seeking to enhance the rigor, clarity, and potential transferability of the lessons they formulate.}, }

Hence, this systematic review explored those impacts and their sustainability post-pandemic. To conduct this systematic review, a thorough literature search was undertaken in electronic databases such as PubMed, Medline, Web of Science, Google Scholar, databases, Embase, and PsycINFO using relevant keywords. We included articles written in English and published in the last 10 years that reported on the impact of telehealth adoption on various patient outcomes and the impact of sustainability post-pandemic. The findings of this systematic review highlight the remarkable impact of telehealth adoption on patient outcomes and the sustainability of these initiatives post-pandemic. Telehealth has proven to enhance various aspects of healthcare, spanning from prevention to follow-up. Another effect of telehealth adoption is the significant reduction in hospitalizations. Furthermore, telehealth profoundly impacts hospital stays, leading to a decrease in all-cause hospital days per patient by 1.07 (95% confidence interval (CI): 1.76 to 0.39) days and a shorter mean hospital stay for condition-related hospitalizations by 89% (95% CI 1.42 to 0.36), providing evidence of efficient healthcare delivery. There was also a reduction in mortality rates for patients receiving telemedicine interventions. Telehealth is also cost-effective while remaining highly effective. Patient satisfaction is another key outcome of telehealth adoption observed. The convenience and reduced expenses of telehealth have garnered positive feedback from patients, reinforcing the desirability of telehealth as a viable alternative to in-person visits. Despite these numerous benefits, barriers and disparities in telehealth adoption and utilization persist, especially in rural hospitals that face challenges, including a lack of Health Information Exchange (HIE) capacity, limited patient engagement capabilities, and the absence of financial reimbursement. This systematic review underscores the remarkable impact of telehealth adoption on patient outcomes and its sustainability post-pandemic. However, barriers and disparities still exist, requiring attention to ensure equitable access to telehealth services. The evidence supports the continued development and implementation of telehealth initiatives to improve healthcare delivery and patient outcomes post-pandemic.}, }

Gender significantly moderated pandemic-related stress. Higher EE scores in women were linked to isolation and caregiving responsibilities, while men's EE often appeared as reward-seeking. Across diverse measures and regions, women consistently exhibited higher EE scores (Cohen's d&#x202f;=&#x202f;0.39). Young adults and students showed a stronger association with EE, suggesting heightened vulnerability. Key predictors included increased food intake, COVID-19-related stress and lifestyle changes, sleep quality, and physical activity.<br><br>CONCLUSION: The predominance of cross-sectional designs limits the ability to draw causal conclusions, and selection bias in studies, often targeting specific groups, restricts generalizability.

This technology constitutes an advanced therapeutic strategy for selective protein degradation, thereby expanding the horizons of drug design. Its significant therapeutic potential extends to treating cancers, viral infections (e.g., HIV and SARS-CoV-2), and chronic diseases. Recent clinical studies on compounds such as ARV-471 have yielded encouraging results, validating the efficacy of this approach. Over the past decade, PROTAC technology has garnered widespread attention in biomedicine for its promise in developing novel targeted therapies. This review will elucidate the broad therapeutic prospects and future challenges of PROTACs by detailing their mechanism of action, recent advances, progress in targeted therapy research, and current clinical trial landscape.}, }

This review examines how the dimensionality of ZnO nanostructures affects biosensor performance, particularly in terms of charge transport, signal transduction, and biomolecule immobilization. The synthesis approaches are discussed, highlighting how they influence crystallinity, defect density, and surface functionalization potential. The impact of immobilization strategies on sensor stability and sensitivity is also assessed. The role of ZnO in various optical detection schemes, including photoluminescence, surface plasmon resonance (SPR), localized (LSPR), fluorescence, and surface-enhanced Raman scattering (SERS), is reviewed, with emphasis on label-free and real-time detection. Representative case studies demonstrate the detection of clinically and environmentally relevant targets, such as glucose, dopamine, cancer biomarkers, and SARS-CoV-2 antigens, with limits of detection in the pico- to femtomolar range. Recent developments in ZnO-based hybrid systems and their integration into fiber-optic and microfluidic platforms are explored as scalable solutions for portable, multiplexed diagnostics. The review concludes by outlining current challenges related to reproducibility, long-term operational stability, and surface modification standardization. This work provides a framework for understanding structure-function relationships in ZnO-based biosensors and highlights future directions for their development in biomedical and environmental monitoring applications.}, }

Focusing on adenoviruses, influenza, rhinoviruses, RSV, and SARS-CoV-2, we explore a series of molecular case studies that reveal both shared strategies and the diverse molecular innovations these respiratory pathogens use to subvert the nuclear transport machinery. We organize these tactics into six recurring strategies: NPC docking and nuclear entry, inhibition of immune-factor import, hijacking nuclear protein transport and karyopherins, sabotage of host mRNA export, degradation of FG-Nups, and exploitation of mitotic nuclear envelope breakdown. These insights not only illuminate fundamental virus-host conflicts but may also point the way toward new therapeutic vulnerabilities in the viruses' attack strategies.}, }

Our analysis reveals how these determinants reinforce societal divisions, exacerbate health inequalities, and influence adherence to public health measures. Furthermore, we discuss the implications of these findings for designing effective interventions that address the root causes of health polarization.

Owing to its antibacterial and antifungal properties, it is an ingredient in an array of commercial products, such as personal care, medical, acrylic, veterinary, and household items. Recent data reveal its frequent presence and widespread exposure in natural environments and human tissues. Studies across multiple species provide compelling evidence of its endocrine-disrupting effects, especially concerning reproductive hormones.

Numerous studies show effects of perinatal maternal psychological distress (e.g., depression) on child brain and behavior. Less attention has been paid to exposure to external real-world stressors (e.g., objective hardship), which are independent of individual characteristics. We systematically reviewed 39 human studies on perinatal maternal stress from natural disasters and disease outbreaks and associations with children's brain structure and function, behavior, and mental health. Studies have mainly focused on the 1998 Quebec Ice Storm or the COVID-19 pandemic, with a handful from other natural disasters. Prenatal maternal objective hardship is related to brain volumes and functional connectivity, though studies have been small and in overlapping samples; no studies to date have examined postnatal maternal objective hardship and brain. Disaster- and disease-related perinatal hardship is related to multiple domains of neurodevelopmental outcomes, including temperament, cognition, and behaviour, with generally negative outcomes (more hardship predicts worse cognition/behaviour). Early gestational exposure is more associated with cognition, though more research is needed to understand windows of vulnerability. The apparent effects of prenatal objective stress on child behavior may occur in part through child brain alterations. Future studies with larger samples are needed, particularly to understand the effects of exposure timing and type, to further investigate sex differences, and to clarify the role of postnatal maternal objective hardship. The COVID-19 pandemic presents a unique opportunity to do this, and several ongoing studies are likely to provide valuable insight in the coming years.}, }

Treatment with low-dose colchicine has been proposed for the secondary prevention of cardiovascular events in individuals at high cardiovascular risk. A previous Cochrane review showed considerable uncertainty regarding the benefits and harms of this approach.<br><br>OBJECTIVES: To evaluate the benefits and harms of low-dose colchicine in the prevention of cardiovascular events in adults with a history of stable CVD or following myocardial infarction or stroke.<br><br>SEARCH METHODS: We conducted a comprehensive search of the literature until February 2025 using Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, the drugs@FDA database, references of key papers, and references of included studies.<br><br>ELIGIBILITY CRITERIA: Randomised controlled trials (RCTs) comparing the use of low-dose colchicine for a minimum of six months versus any control intervention in patients of any age with cardiovascular disease (i.e. history of stable cardiovascular disease, previous myocardial infarction or stroke).<br><br>OUTCOMES: Our critical outcomes were all-cause mortality, myocardial infarction, and serious adverse events. Our important outcomes were cardiovascular mortality, stroke, all-cause hospitalisations, coronary revascularisation (percutaneous coronary intervention (PCI)/angioplasty or coronary artery bypass graft (CABG)), quality of life, and gastrointestinal adverse events (i.e. diarrhoea, nausea, abdominal pain, or vomiting).<br><br>RISK OF BIAS: Two authors independently assessed the risk of bias using the Cochrane RoB2 tool.<br><br>SYNTHESIS METHODS: We conducted meta-analyses using the random-effects model. We generated forest plots to facilitate visualisation of the data. We did not perform any subgroup analysis. We used GRADE to assess the certainty of evidence for all critical outcomes and for cardiovascular mortality, stroke, and coronary revascularisation. This was carried out by two review authors working independently.<br><br>INCLUDED STUDIES: We included 12 studies involving 22,983 randomised participants. The follow-up in the studies ranged from 6 to 80 months. Overall, 11,524 participants were assigned to low-dose colchicine treatment and 11,459 were assigned to a control intervention, which constituted either usual care plus placebo or usual care only. The doses of colchicine used were 0.5 mg once or twice daily. At baseline, the mean age of participants ranged from 57 to 74 years. Most participants (79.4%) were male.<br><br>SYNTHESIS OF RESULTS: There is high-certainty evidence that low-dose colchicine treatment reduces the risk of myocardial infarction, with a risk ratio (RR) of 0.74 (95% confidence interval (CI) 0.57 to 0.96; 22,153 participants, 8 studies; I[2] = 51%), yielding an absolute risk reduction of 9 fewer events (95% CI 16 fewer to 2 fewer) per 1000 patients, when the myocardial infarction rate is about 4% (36 events per 1000 patients) in the control group. There is also high-certainty evidence that low-dose colchicine reduces the risk of stroke with a RR of 0.67 (95% CI 0.47 to 0.95; 22,483 participants, 10 studies; I[2] = 40%), yielding an absolute risk reduction of 8 fewer events (95% CI 12 fewer to 1 fewer) per 1000 patients, when the stroke rate is about 2% (22 events per 1000 patients) in the control group. There is high-certainty evidence that the use of low-dose colchicine does not increase the rate of serious adverse events (RR 0.98, 95% CI 0.94 to 1.02; 15,677 participants, 4 studies; I[2] = 0%). However, gastrointestinal adverse events were more common under treatment with colchicine (RR 1.68, 95% CI 1.11 to 2.57; 22,185 participants, 10 studies; I[2] = 91%). For all other outcomes assessed, the evidence is of moderate certainty. Colchicine probably results in little to no difference in all-cause mortality (RR 1.01, 95% CI 0.84 to 1.21; 22,747 participants, 10 studies; I[2] = 1%; moderate-certainty evidence), in cardiovascular mortality (RR 0.94, 95% CI 0.73 to 1.22; 22,271 participants; 8 studies; I[2] = 13%; moderate-certainty evidence), and coronary revascularisation (RR 0.83, 95% CI 0.64 to 1.08; 13,705 participants, 5 studies; I[2] = 40%; moderate-certainty evidence). There is no evidence about the benefits or harms of colchicine on quality-of-life or on the risk of all-cause hospitalisation.<br><br>AUTHORS' CONCLUSIONS: People with cardiovascular disease using low-dose colchicine as secondary prevention for at least six months benefit from reduced rates of myocardial infarction and stroke, without an increase in serious adverse events. Moderate-certainty evidence did not show a benefit from low-dose colchicine for the risk of mortality (i.e. all-cause and cardiovascular mortality) or coronary revascularisation rates. Colchicine use was associated with an increased risk of gastrointestinal adverse events, which were typically described as mild and transient in nature. Additional studies are warranted to investigate the benefits and harms of low-dose colchicine in relevant subgroups and in specific indications, such as long-term use in individuals with stable coronary artery disease versus limited-time use following acute coronary syndrome.<br><br>FUNDING: Review author FE was supported by the Margot und Erich Goldschmidt &amp; Peter Ren&#xe9; Jacobson Foundation.

This is a nascent evidence base, lacking robust research designs and characterised by small sample sizes; the results describe the factors observed to be important in the delivery of care. Care provision is extremely variable; no models of optimal care have been put forward or tested. Challenges to care provision occur at every level of the care system. At macro level, service-level agreements and policies vary: at meso level, team-working, communication technology solutions and equipment availability vary: at micro level, GPs' interests in providing PEoLC vary as does their training. No study addresses residents' and relatives' experiences and expectations of GPs' involvement in PEoLC in RACFs.<br><br>CONCLUSIONS: The limited evidence base highlights that GP care at end of life for RACF residents varies greatly, with enablers and challenges at all levels in the existing care systems.

It presents early in life with severe, recurrent opportunistic infections. Early diagnosis and hematopoietic stem cell transplantation (HSCT) are vital for patient survival. Cernunnos/XLF deficiency is an autosomal recessive form of SCID caused by mutations in the NHEJ1 gene, which plays a critical role in repairing DNA double-strand breaks. First described in 2006, this condition remains exceedingly rare, with only about 55 cases reported to date. This study aimed to describe a novel infant with Cernunnos/XLF deficiency and to review previously reported patients carrying the same variant, thereby expanding the clinical spectrum of this rare disease.<br><br>METHODS: With written informed consent, we retrospectively evaluated a pediatric patient with Cernunnos/XLF deficiency followed at our clinic. Demographic, clinical, laboratory, and radiological findings were reviewed. The diagnosis was based on clinical and immunological features and confirmed via clinical exome sequencing. A literature review was conducted to compare the genotype-phenotype correlations of previously reported patients carrying the same NHEJ1 variant.<br><br>RESULTS: We report an infant who was hospitalized at 6.5&#xa0;months of age with a preliminary diagnosis of meningitis and was subsequently diagnosed with Cernunnos/XLF deficiency. The patient exhibited microcephaly, growth retardation, recurrent infections, prolonged SARS-CoV-2 PCR positivity, and localized BCGitis following live Bacillus Calmette-Gu&#xe9;rin (BCG) vaccination. Immunological evaluation revealed T- and B-cell lymphopenia and hypogammaglobulinemia. Genetic testing confirmed a homozygous nonsense mutation in NHEJ1. HSCT from a matched sibling donor was performed.<br><br>CONCLUSION: This study describes a rare case of Cernunnos/XLF deficiency diagnosed in early infancy, underscoring the value of early recognition and the critical role of genetic testing and HSCT. It also expands the clinical spectrum of the disease and provides a comparative perspective with previously reported patients carrying the same mutation. In infants presenting with unexplained infections or complications related to live vaccines, inborn errors of immunity should be considered. Our findings emphasize the importance of timely diagnosis and comprehensive, multidisciplinary follow-up, particularly in patients with additional complications.}, }

While preliminary evidence suggests that telehealth-delivered, remote eating disorder treatment may offer improved accessibility with similar effectiveness to in-person treatment, research on these services remains limited, particularly regarding the communities that are disproportionately affected by barriers to standard care. This scoping review sought to map the existing research on real-world patient outcomes in remote eating disorder treatment, identify knowledge gaps, and prioritize areas for future studies.<br><br>METHODS: This review followed the Joanna Briggs Institute methodology for scoping reviews. It comprises observational evaluations of telehealth-delivered, remote eating disorder treatment conducted in routine clinical settings. An electronic database search was performed in PsycINFO, PubMed, and ProQuest Dissertations &amp; Theses Global in August 2024 and updated in September 2025.<br><br>RESULTS: Following the search and screening process, 27 articles, comprising six case reports and 21 cohort/case series designs, were deemed eligible for inclusion. Remote treatments evaluated differed across level of care, therapeutic modalities, provider types, dosage, and adjunctive technologies used. Just under half of the studies compared outcomes from remote and in-person treatment, while the remainder examined remote treatment alone. Articles were published between 2011 and 2025 and, when excluding case reports, nearly 60% evaluated programs that rapidly transitioned to remote delivery due to COVID-19. While demographic reporting was limited and inconsistent, available information indicated that participants ranged from three to 75 years old and were predominantly White, cisgender women/females diagnosed with anorexia nervosa. Though preliminary, findings tentatively suggest that remote eating disorder treatment can yield improvements across core outcome domains, largely comparable to in-person settings. Less is known about how outcomes may differ across demographic groups.<br><br>CONCLUSIONS: Overall, this body of literature remains small and characterized by limitations and inconsistencies, including differences in the treatment services evaluated as well as disparities in study design, methodology, and reporting. Utilization of remote treatment by historically excluded groups remains low, calling for further reflection around its accessibility for target communities.

We also highlight virus-induced epigenetic changes across diverse cell populations that contribute to COVID-19 pathogenesis. Notably, the virus reprograms hematopoietic stem and progenitor cells, leading to long-lasting alterations in innate immunity, a phenomenon known as "trained immunity." These epigenetic modifications are maintained in differentiated daughter cells and may explain the persistent inflammation and other symptoms of long COVID. Furthermore, we discuss emerging epigenetic biomarkers of disease severity, including methylation signatures in genes such as AIM2, HLA-C, and PARP9, as well as dysregulated miRNA profiles. Understanding this complex interplay between the virus and the host's epigenetic landscape is crucial for developing new therapeutic approaches that target specific epigenetic modifications to suppress pathological processes and improve clinical outcomes for COVID-19 patients.}, }

A comprehensive search of various databases was conducted to identify studies reporting MIS-related complications in pediatric and adult populations post-COVID-19 infection. Screening, data extraction, and cross-checking were performed by two independent reviewers. Only 64 studies met our inclusion criteria, and compiled results revealed that cardiac complications were the predominant manifestation followed by gastrointestinal, hematologic, neurological, and mucocutaneous involvement. Laboratory findings consistently demonstrated elevated inflammatory markers including CRP, ferritin, D-dimer, and IL-6. Most patients required hospitalization, and many needed intensive care; treatment typically involved IVIG, corticosteroids, and biologic therapies. While most patients recovered, a subset experienced persistent complications. These findings highlight the importance of early recognition, multidisciplinary management, and structured follow-up for MIS. Future research is warranted to clarify the underlying mechanisms, risk factors, and long-term outcomes associated with MIS in post-COVID-19 patients.}, }

Recent studies, however, have revealed its extensive therapeutic relevance upon release into circulation, functioning not only as a biomarker for cellular injury but also as an active modulator of cardiovascular homeostasis and critical disease. High levels of circulating DPP3 (cDPP3) have been linked to the causes of cardiogenic shock, septic shock, acute coronary syndromes, heart failure, and serious viral diseases like COVID-19. Its enzymatic breakdown of angiotensin II disrupts vascular tone and myocardial contractility, leading to hemodynamic instability and multi-organ failure. In numerous cohorts, cDPP3 levels reliably correspond with disease severity, acute renal damage, and death, but dynamic trajectories yield superior predictive information relative to single assessments. In addition to risk stratification, translational studies utilizing rodent and porcine models illustrate that antibody-mediated inhibition of cDPP3 with the humanized monoclonal antibody Procizumab reinstates cardiac function, stabilizes renal perfusion, diminishes oxidative stress and inflammation, and enhances survival. First-in-human experiences in patients with refractory septic cardiomyopathy have further emphasized its therapeutic promise. DPP3 is a good example of a biomarker and a mediator in cardiovascular and critical care. Its growing clinical and translational profile makes cDPP3 a strong predictor of bad outcomes and a prospective target for treatment. Ongoing clinical trials using Procizumab will determine if neutralizing cDPP3 can lead to enhanced outcomes in individuals with cardiogenic and septic shock. This review outlines the physiological mechanisms, clinical implications, and emerging therapeutic potential of DPP3 in cardiovascular and critical care. Ongoing trials with Procizumab will clarify whether neutralizing cDPP3 can improve outcomes in patients with cardiogenic and septic shock.}, }

Retention has thus become a critical concern for healthcare institutions. Identifying the factors influencing nurses' turnover intentions (TIs) and improving workplace conditions may help to reduce attrition. This study investigates the relationships among TI, work stress (WS), and job burnout (JB), examining variations across healthcare settings and comparing the periods before and after the COVID-19 pandemic. Methods: This study systematically reviews 28 studies published between 2011 and 2025, retrieved from Taiwan's Master's and Doctoral Thesis Knowledge Value Added System, Airiti Library, and Google Scholar. The review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA) guidelines. The data were analyzed using a combined approach of meta-analysis and structural equation modeling. Results: The findings of this study indicate that WS has a statistically significant impact on TI (path coefficient = 0.281, 95% CI: 0.102 to 0.459, p = 0.002). Similarly, JB significantly influences TI (path coefficient = 0.342, 95% CI: 0.163 to 0.520, p < 0.001). WS also has a strong and significant effect on JB (path coefficient = 0.612, 95% CI: 0.485 to 0.739, p < 0.001). These results suggest that WS has a particularly strong effect on JB among nurses working in non-medical center hospitals in Taiwan. Additionally, no significant differences were found in the relationships among TI, WS, and JB before and after the COVID-19 pandemic. Conclusions: Based on the findings of this study, it is recommended that healthcare administrators closely monitor the stress experienced by nursing staff and identify the key factors that lead to WS and JB. Developing targeted policies for different healthcare settings may help to reduce nurses' intentions to leave their jobs.}, }

Results: Of 5230 records identified (4720 after deduplication), 200 full texts were assessed and 19 were included. Most used horizontal FL across multiple institutions for communicable diseases, COVID-19, tuberculosis and some chronic conditions. Reported gains included privacy preservation across sites, better generalizability from diverse data, near real-time intelligence, localized risk stratification, and support for resource planning. Common barriers were non-IID data, interoperability gaps, compute and network limits in low-resource settings, unclear legal pathways, and concerns about fairness and transparency. Few studies linked directly to formal public-health policy or low-resource deployments.

The gastrointestinal (GI) tract is one of the most vulnerable human organ system to virus-mediated tumorigenesis as a result of frequent exposure to viral infections and various immunological processes. The present review aims to describe the dual roles of viral infections in the development of gastrointestinal cancers (GICs), with a focus on Human Immunodeficiency Virus (HIV) and Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). HIV represents an oncological challenge in the era of effective antiretroviral therapy (ART), where significant immune dysfunction, persistent inflammation, and gut microbiome disruption render infected patients more susceptible to various GICs. On the other hand, SARS-CoV-2 is an emerging viral pathogen whose potential role in oncogenesis remains controversial yet biologically plausible. In this context, SARS-CoV-2 tropism to the gastrointestinal tissues and its capacity to drive cytokine storms, profound dysbiosis, and immune exhaustion raise significant questions regarding its potential to act as a pro-tumorigenic factor.

Diagnosing any of these conditions in a home setting raises both logistical and ethical issues that may prevent home testing from becoming the public health benefit its advocates envision. Over the last century, early home tests such as the first urine glucose screening tests for diabetes and the first home pregnancy tests generated very similar expectations of substantial public health benefits.

Soon after it was disseminated globally, the virus underwent adaptive radiation, resulting in the generation of multiple dominant variants. Later variants drove earlier ones to extinction in a series of selective sweeps. The nature of adaptation was shifting molecular specialization, with the spike protein losing binding affinity toward bat cells to gain affinity toward human cells, losing replicative fitness in lung cells to gain fitness in nasal cells. Evolution of the spike protein was constrained between two beneficial results: enhancing receptor binding and evading neutralizing antibodies. Because there are limited ways of functional improvement, multiple variants converged on the same spike mutations, with higher-impact mutations fixed before lower-impact mutations, giving a new meaning to diminishing-returns epistasis. Later genetic changes became repetitive and cyclical. The Delta variant represented an evolutionary dead end. Evolution of the virus also demonstrated punctuated equilibrium, with saltatory changes producing highly mutated variants, which subsequently experienced gradual structural and functional drifts. While structural proteins experienced strong positive and purifying selections, nonstructural and accessory proteins accumulated neutral and deleterious mutations, most of which remain unfixed. Selection of adaptive missense mutations resulted in deoptimization of codon usage. These phenomena point to Muller's ratchet in action. The higher codon usage score in the initial Omicron variant was probably due to long-term preservation of the virus in an immunocompromised host, where low immune pressure prevented genetic degradation.}, }

Eligible publications included clinical studies reporting immune response to COVID-19 vaccination in CKD patients without dialysis or KT, CKD patients undergoing dialysis, as well as CKD patients with KT. Demographics, measurements and results of their humoral and cellular response were evaluated, and the quality of studies were assessed using the Joanna Briggs Institute (JBI) critical appraisal tool and the Newcastle-Ottawa quality assessment scale (NOS).<br><br>RESULTS: A total of 31 eligible studies were identified. A decreased proportion of patients with KT showed anti-S IgG positivity after the 2[nd] (67%) and 3[rd] (56.6%) dose of vaccination. Similarly, a decreased proportion of these patients presented S-specific T-cell response after the 2[nd] (17.7%) and 3[rd] (12.9%) dose. Though lower anti-S IgG titers in patients with CKD or on dialysis, as well as T-cell response in patients on dialysis were reported to be lower after the 2[nd] or 3[rd] dose of vaccination, conflicting results were reported by other studies. Limited studies on correlated change between humoral and cellular immune response revealed a low rate of co-presence of the two in patients with dialysis, though antibody level was correlated with rate of cellular response, while no such correlation was revealed in patients with KT.<br><br>CONCLUSION: The study provides crucial information on features of humoral and cellular immune responses to COVID-19 vaccinations in CKD patients, and suggests possible directions for strategy of management such as antibody monitoring, additional booster dose or immunomodulatory therapies not only for acute COVID-19 but also for long COVID-19.}, }

In coronavirus disease 2019 (COVID-19), increasing evidence links exhausted T-cell phenotypes with poor clinical outcomes, including severe disease, delayed viral clearance, and persistent symptoms associated with Long COVID. Exhaustion results from prolonged antigenic stimulation and inflammatory signals and is marked by transcriptional reprogramming, metabolic and epigenetic dysregulation, and co-expression of inhibitory receptors such as programmed cell death protein-1 (PD-1), T-cell immunoglobulin and mucin-domain containing-3 (TIM-3), and cytotoxic T-lymphocyte-associated protein 4 (CTLA-4). Notably, exhausted phenotypes in COVID-19 frequently coexist with hyperactivation, raising the unresolved question of whether inhibitory receptor expression reflects transient activation or irreversible dysfunction. Emerging therapeutic strategies to reverse these dysfunctional states include immune checkpoint inhibitors, cytokine modulation, metabolic interventions, and epigenetic therapies, although their clinical translation remains at an early stage. Critical research gaps include the scarcity of longitudinal data, incomplete profiling of T-cell subsets across disease stages during COVID-19 and Long COVID-19, and contradictory evidence of vaccine-induced exhaustion with limited understanding of its consequences. This non-systematic literature review synthesizes current advances in COVID-19 immunopathology and therapeutic strategies, underscoring that understanding T-cell exhaustion is crucial to improving outcomes and shaping next-generation immunotherapies and vaccines.}, }

Screening and data extraction were completed in Covidence by two independent reviewers. Data were analysed using descriptive and inductive content analysis.<br><br>RESULTS: Eighteen articles met inclusion criteria. Key findings were: (1) special medical exemptions are inconsistently granted; (2) individuals seeking special medical exemptions often support vaccination broadly, but express context-specific health concerns; (3) evidence on how vaccines affect the medical conditions underlying exemption requests were often lacking, leaving key gaps for decision-making not addressed by current criteria; (4) trust in clinicians who prioritised individual health needs over strict policy shaped families' subsequent vaccine decision; and (5) special medical exemptions can have wider implications from an individual or interpersonal level to a broader community and policy level.<br><br>CONCLUSION: Special medical exemptions currently lack definitional clarity and standardised criteria, leading to inconsistent and potentially inequitable exemption decisions.

The high sequence conservation across coronaviruses and absence of closely related human proteases make M[pro] an attractive target for selective antiviral interventions. Recent efforts in drug discovery have led to the development of a wide spectrum of M[pro] inhibitors, including covalent peptidomimetics (e.g., nirmatrelvir) and non-covalent small molecules with enhanced pharmacological profiles, such as ensitrelvir. Structure-based drug design, fragment-based drug discovery (FBDD), high-throughput screening (HTS), and in silico approaches have contributed to identification of novel scaffolds and optimization of binding interactions within the catalytic pocket. Non-covalent inhibitors offer reversible binding mechanisms that reduce off-target effects and are particularly promising for clinical translation. However, challenges such as the limited oral bioavailability of peptidomimetic compounds, metabolic instability, and emerging resistance highlight the need for further optimization. Ongoing research is exploring prodrug strategies, advanced delivery systems, and combinatorial regimens that integrate M[pro] inhibitors with other antivirals to achieve synergistic effects and suppress resistance.

The catalytic triad and several functional domains, including the flexible BL2 loop that regulates access to the viral polyprotein substrate and inhibitor, as well as the SUb1 and SUb2 binding sites for ISG15/Ub recognition, are structural features of PLpro.

The proteases of many such pathogens have been cloned, characterized and in some cases also crystallized in complex with inhibitors, but no compounds progressed yet to clinical trials. There are several relevant challenges in designing PIs as novel antivirals, such as: (i) the drug design strategies of peptidomimetic inhibitors, which are many times complex and expensive; (ii) the difficulties in identifying non-peptidomimetic PIs; (iii) the selectivity for the target versus host proteases of the identified PIs; (iv) their metabolism, absorption and in vivo antiviral activity, and, most importantly, (v) the emergence of drug/multidrug resistance due to the high mutation rates of many viruses. Many of these challenges started to be approached by innovative strategies which will be duscussed in the chapter.}, }

Given their relative simplicity and lower resource intensity as compared with invasive mechanical ventilation, these mechanisms of respiratory support represent an attractive opportunity for use in patients with acute respiratory failure in resource-constrained settings. High flow oxygen in particular has the potential to provide high levels of respiratory support with relatively low levels of human and other resources to a wide variety of patients with respiratory failure, including those with delirium or obtundation. Even after the COVID-19 pandemic, during which utilization of these techniques increased in high-income countries, low and lower-middle income countries still have little access to advanced non-invasive respiratory support. Evidence from high-income countries and limited evidence from low-income countries suggest that these respiratory support methods may be particularly beneficial in resource-constrained settings; however, the evidence also suggests that the populations chosen and particularly the attention and resources invested in implementation are critical in ensuring the safety and effectiveness of non-invasive support. While non-invasive respiratory support does not require the complex training and monitoring needed for invasive support (e.g. specific risks associated with the endotracheal tube, sequelae of sedation, complex ventilator modes), it nonetheless requires resources in order to be applied effectively. Particular domains that need careful consideration are: clinical systems of care; oxygen consumption and connector compatibilities; human resources and training; location within the hospital; acceptability; cost; and device characteristics. In addition, ongoing research is needed that includes randomized controlled trials with attention to context, so that clinicians in resource-constrained settings can apply relevant evidence for non-invasive respiratory support for patients in their settings.}, }

A recent global rise in hMPV detections, detailed in reports from China, Europe, and the USA, likely reflects both expanded testing and the re-establishment of seasonal circulation following the COVID-19 pandemic. Co-infections with respiratory viruses, including RSV and influenza, contribute to severe clinical outcomes and hospital burden. Multiplex RT-PCR remains the most sensitive and widely used diagnostic method for detection of hMPV, outperforming conventional PCR approaches, while metagenomic sequencing and CRISPR-based assays are primarily research tools. Diagnostic sensitivity also varies with sample source, and access to advanced technologies remains globally uneven. Despite its growing clinical impact, no approved antiviral is available. Promising candidates, including monoclonal antibodies against the fusion protein, siRNA therapies, and mRNA-based vaccines, are in the early stages of development.

This approach overcomes the long-standing limitation of intracellular delivery of antibody-based biologics. By expressing antiviral nanobodies directly inside infected cells via lipid-nanoparticle-encapsulated mRNA, it becomes possible to disrupt essential protein-protein interactions within viral RTCs. Using SARS-CoV-2 non-structural protein 9 (NSP9) as a proof-of-concept, we show that stabilizing non-functional NSP9 oligomers can inhibit viral replication.

Even in high-resource nations, many individuals still lack adequate care, a gap exacerbated by the COVID-19 pandemic. Brief psychological interventions (BPIs) offer a structured, short-term therapeutic approach to address this need. Typically delivered in fewer than ten sessions, BPIs incorporate evidence-based therapy components and can be administered by paraprofessionals, non-credentialed individuals trained to provide mental health support. This review synthesizes research on paraprofessionally delivered BPIs by describing study characteristics across populations, settings, and intervention modalities, characterizing the paraprofessional workforce, and summarizing reported mental health outcomes and patterns of effectiveness. A PsycINFO and PubMed search identified 47 articles, including 45 unique studies. To provide a clearer picture of effectiveness, box-score analyses were conducted on randomized controlled trials (RCTs) and pilot/feasibility RCTs. Findings indicate that paraprofessional-delivered BPIs, particularly those grounded in cognitive-behavioral therapy (CBT) and delivered remotely, are consistently effective across diverse populations and contexts. The evidence base is strongest for adult populations and posttraumatic stress disorder (PTSD) outcomes, with weaker support for adolescents and school-based programs. Paraprofessionals' cultural and community alignment also enhanced engagement and reduced stigma-related barriers. Nonetheless, inconsistencies in training, supervision, intervention fidelity, and recruitment criteria present challenges for scalability. This review highlights the absence of a rigorously tested definition of BPIs and the lack of consensus on the term paraprofessional. It underscores the need for standardized training and supervision guidelines to ensure fidelity and sustainability. Further research is essential to refine best practices and optimize paraprofessionals' integration into mental health systems, thereby improving accessibility and equity.}, }

Specifically, it examined (1) the types of AI tools in use, (2) their purposes and implementation contexts, and (3) the professional and institutional actors leading these efforts, including the role of nurses.<br><br>METHODS: Using the Joanna Briggs Institute's population, concept, and context framework, a structured search in Ovid MEDLINE was conducted, which was guided by the "5Cs" framework for health emergency preparedness from the World Health Organization (WHO). The search focused on English-language, peer-reviewed studies from 2020 that used AI tools for infectious disease control within real-world public health practice. Nonoriginal articles, simulation-only studies, and studies that lacked real-world implementation were excluded.<br><br>RESULTS: Out of 600 screened studies in Ovid MEDLINE, 10 met the inclusion criteria. Two major AI types were identified: machine learning (ML) algorithms and language-based tools such as chatbots and large language models. ML tools supported outbreak detection, risk stratification, and resource allocation, while language-based tools promoted health communication, particularly around immunization and HIV prevention. Studies were conducted in a diverse range of countries, including several low- and middle-income countries, and used national datasets or surveillance systems. Despite nurses comprising half of the global health workforce, no nursing-affiliated authors were found among first or corresponding authors, and no nurses were represented in the broader authorship of the included studies.<br><br>CONCLUSIONS: AI technologies are being increasingly applied to support public health responses to infectious diseases, with applications ranging from predictive analytics to real-time public engagement. However, adoption remains limited in scale, scope, and professional diversity. The near-total absence of nursing participation in AI-related public health research is particularly striking and represents a missed opportunity for inclusive innovation. Strengthening implementation research and advancing informatics education among nursing professionals are critical next steps to ensure that AI tools reflect the realities of public health practice and promote equitable outcomes.}, }

Recent data indicates that stroke was the third leading cause of death (10.7 % of all deaths), following ischemic heart disease and COVID-19. In 2021, nearly 94 million people were living with the consequences of a stroke, and about 12 million new cases were reported. Major risk factors for stroke include high systolic blood pressure, exposure to ambient particulate matter, smoking, and elevated levels of low-density lipoprotein cholesterol (LDL-C), with LDL-C contributing to nearly one-third of all ischemic strokes. In primary prevention, many at-risk individuals have undiagnosed or poorly managed lipid disorders, including elevated lipoprotein(a). The challenge persists in secondary prevention, where up to 40 % of individuals at risk of recurrent ischemic stroke experience a recurrence within five years. A key reason for this is the inadequate diagnosis and management of lipid disorders, underscoring the necessity for early and intensive (upfront) combination lipid-lowering therapy (LLT) to meet treatment goals promptly after an event. Unfortunately, data indicates that up to 40 % of post-stroke patients receive no LLT, and many more receive inadequate treatment. Additionally, existing guidelines for LLT in both primary and secondary stroke prevention are often inconsistent and outdated. Similarly, the understanding of the effects of LDL-C and LLT on the risks of haemorrhagic stroke and dementia remains limited, emphasizing the need for clear and practical guidance. Thus, within this Consensus Paper we aimed to provide consistent, easy-to-follow, and practical guidance on lipid targets, along with clear pathways for effectively treating patients with lipid disorders who are at risk for stroke and those who have experienced one. This approach is intended to help reduce the risk of recurrent ischemic strokes and their associated complications.}, }

Among desk-based workers, sitting at work contributes substantially to the daily time spent sedentary. Working environment can influence SB. Thus, we aimed to investigate the evidence on the impact of working from home/teleworking (WFH), which is now a common working environment versus working onsite on SB and PA.<br><br>METHODS: We conducted a systematic review comparing SB and PA of workers WFH compared to onsite work. We searched Pubmed, Embase and SPORTDiscus (last search: June 2025). At least two reviewers independently screened the studies and rated the of risk of bias based on adapted existing tools. We included studies on adult workers, which at least part-time WFH with comparison group working onsite, reporting SB or/and PA-outcomes per workday/work time. Data extraction was done by one reviewer and checked by two reviewers. Results were described qualitatively and random-effect meta-analyses for daily sedentary time (ST), sitting breaks, and steps were performed.<br><br>RESULTS: We included 38 studies (from 42 articles, with n&#x2009;=&#x2009;282,264 subjects) comparing WFH and onsite work. Four of these studies were rated as having a &#x201c;low&#x201d; risk of bias. SB was described in 23 studies (with n&#x2009;=&#x2009;209,267 subjects). A meta-analysis of studies reporting quantitative results suggests an increase in ST of 31&#xa0;min (95% CI 14 to 48; I[2]&#x2009;=&#x2009;57.5%; 7 studies) during work hours when WFH. PA was described in 36 studies (with n&#x2009;=&#x2009;270,617 subjects), and the meta-analysis found a decrease in daily steps of 2564 (mean difference: &#x2212;&#x2009;2564; 95% CI -3809 to -1320, 289; I[2]&#x2009;=&#x2009;91.4%; 7 studies) when WFH.<br><br>CONCLUSION: We found SB tends to increase and daily steps tend to decrease when WFH compared to onsite work. Studies of PA varied in their methods and results, and few studies measured movement. As most of the studies (n&#x2009;=&#x2009;31) were conducted during the COVID-19 pandemic, that may have influenced the results. Nevertheless, workplace interventions that aim to reduce SB and promote PA need to be adapted to the home working environment.<br><br>REGISTRATION NUMBER: CRD42022349442.<br><br>SUPPLEMENTARY INFORMATION: The online version contains supplementary material available at 10.1186/s12889-025-24960-x.}, }

The outbreak of COVID-19 in late 2019, which subsequently became a global pandemic, has had a profoundly adverse impact on Nigeria's public health system. Conversely, until its certification by the WHO African Region in 2020, Nigeria was considered a Polio-endemic country. Similarly, Cholera is a recurrent epidemic in Nigeria. It remains an incessant and seasonal public health issue, bedeviling Nigerian society, especially in regions that struggle with inadequate water and sanitation facilities, which are widespread. In Africa's most populous nation, the media have been indispensable and powerful during emergencies, such as disease outbreaks. Consequently, media coverage and reports of COVID-19, Polio, and Cholera in Nigeria are critical areas that provide clear perspectives and require attention, as the media can inform and shape public perception during such outbreaks. This study, therefore, explored the reporting trends on disease outbreaks of COVID-19, Polio, and Cholera in Nigeria. The study was guided by the Arksey and O'Malley framework for Scoping reviews. Out of 250 articles initially identified, 98 met the inclusion criteria, with 79 accessible for analysis. Findings reveal that 90% of studies focused on COVID-19, with comparatively less attention given to other significant outbreaks such as Cholera (6%) and Polio (4%). It was also found that the majority (76%) of the studies only paid little attention to the intervention strategies for managing Polio, Cholera, and COVID-19 19, which the Nigerian mass media dominantly reported, and that most of the studies were on conventional media (newspapers, magazines, radio, and TV) coverage. Significant gaps were found in the reporting of advocacy and behaviour change to mitigate the spread of diseases. There was inadequate evidence on the patterns and directions of media coverage of Polio and Cholera due to the under-coverage of the two diseases. The study concludes that media coverage of disease outbreaks, when sourced from top-rated journals, undoubtedly provides valuable insights into the media's coverage of public health interventions for managing future epidemics.}, }

Lipid nanoparticles (LNPs), the most clinically validated non-viral delivery platform, address these challenges by encapsulating and protecting mRNA, promoting cellular uptake, and mediating endosomal escape. mRNA-LNP vaccines leverage a "rapid design + flexible production" advantage, decisively demonstrated by the success of COVID-19 vaccines such as BNT162b2. This review systematically analyzes mRNA-LNP vaccine development, focusing on core optimization strategies: (1) mRNA sequence engineering (nucleoside modification and UTR/poly(A) tail optimization) to enhance stability and translation efficiency; (2) LNP formulation (component ratio optimization, SPOT strategies, etc.) to modulate immune responses and enable organ targeting; and (3) LNP surface functionalization (with small molecules, peptides, and antibodies) for precise specific cell or organ targeting. Although multiple candidate vaccines for infectious disease prevention and cancer treatment have entered clinical trials, their clinical translation is still limited by insufficient targeting accuracy, potential immunogenicity and toxicity, and the challenge of universal delivery systems. Future breakthroughs require the integration of multidisciplinary innovations, focusing on the development of degradable lipids and novel targeting ligands to improve delivery precision, the application of more biocompatible polymers (such as pSar and POx) to replace PEG to enhance safety, and the use of artificial intelligence (AI) to accelerate LNP formulation design and performance prediction. This review summarizes the key optimization strategies and clinical progress and explores future directions to overcome the existing bottlenecks and promote mRNA-LNP technology as the cornerstone of next-generation precision medicine.}, }

HFNT, delivered through dedicated nasal cannulas, provides low levels of positive airway pressure, anatomical dead space washout, allows good patient tolerance and can be used during CPAP or BiPAP breaks. CPAP and BiPAP, administered through various interfaces (e.g., facemasks, oro-nasal masks, or helmets), can deliver higher positive pressure, thereby increasing end-expiratory lung volume, reducing intrapulmonary shunt and oxygenation, with potential benefits on respiratory mechanics as well. BiPAP also delivers pressure support, aiding CO2 clearance and respiratory muscle unloading, which is especially useful in hypercapnic respiratory failure. Increased intrathoracic pressure also reduces right ventricle preload and left ventricle afterload, which is beneficial in patients with impaired left ventricular function. Non-invasive respiratory support indications depend on the cause of acute respiratory failure. In hypercapnic respiratory failure with respiratory acidosis, BiPAP via facemask is strongly recommended to prevent intubation and reduce mortality. In cardiogenic pulmonary edema, either CPAP or BiPAP is recommended, while HFNT can be useful for patients requiring prolonged support or when CPAP/BiPAP is not tolerated even after ventilator and interface settings optimization. In de-novo acute hypoxemic respiratory failure, HFNT should be considered as the first-line treatment, regardless of the aetiology: however, in COVID-19-related AHRF CPAP can be considered to avoid intubation. The choice of non-invasive respiratory support interface in both cardiogenic and non-cardiogenic AHRF should aim at minimizing leaks, optimizing CO2 clearance, and maximizing patient tolerance. Monitoring is essential during non-invasive respiratory support to assess patient's response to treatment and to avoid delaying invasive respiratory support when needed, particularly in hypoxemic patients to avoid intubation delays and prevent patient-self-inflicted lung injury: physiological parameters, clinical scores, and lung ultrasound may help assess the risk of NIV failure. Monitoring tidal volume is valuable but challenging because of leaks. Though not widely used, esophageal pressure monitoring can assess patient effort and transpulmonary pressure. Additionally, electrical impedance tomography is an emerging tool for detecting asynchronous breathing and pendelluft phenomena.}, }

Data on symptoms of anxiety, depression, and stress, as well as attrition rates, were analysed using frequentist random-effects network meta-analyses. One hundred and forty-two studies with 20,470 participants were included. Emotional freedom technique, art-based therapy, stress management, mindfulness- and acceptance-based intervention, positive psychotherapy, yoga therapy, and cognitive behavioural therapy showed significant effects in reducing anxiety symptoms compared with no treatment and treatment as usual. For depressive symptoms, positive psychotherapy, mindfulness- and acceptance-based intervention, cognitive behavioural therapy, and yoga therapy demonstrated significant superiority over no treatment or treatment as usual, with positive psychotherapy also outperforming expressive writing. Regarding stress symptoms, multi-component therapy and yoga therapy produced greater improvements than no treatment, and positive psychotherapy surpassed expressive writing. In terms of attrition rates, resilience training, art-based therapy and yoga therapy had higher dropout rates than no treatment and several other interventions. Sensitivity analyses yielded largely consistent results, confirming the robustness of the main findings. The confidence ranged from moderate to very low. Publication bias was not observed. This study illuminates and compares the efficacy and attrition rate of several psychosocial interventions in attenuating mental health symptoms among COVID-19-affected individuals.

This narrative review outlines its applications, cost benefits, and adoption barriers. Studies demonstrate high patient satisfaction, especially for postoperative consultations and prostate-specific antigen (PSA) tracking. Virtual care is highly effective for managing conditions like nephrolithiasis and benign ureteric colic; one quality improvement study focusing on ureteric colic successfully avoided 71.1% of face-to-face follow-ups while maintaining high safety and patient satisfaction (93.1%). The financial advantages are significant, with virtual stone clinics reducing waiting times and saving patients an average of $147 to $186 per visit by minimizing travel costs and time away from work. Despite these benefits, widespread adoption faces hurdles. Key challenges include a lack of patient trust in virtual sessions compared to in-person care, particularly among minority groups. Furthermore, technological barriers, such as inadequate digital literacy and a lack of broadband access, disproportionately affect elderly and ethnic minority populations, which risks exacerbating existing health disparities. Telemedicine is also limited by its unsuitability for conditions requiring a physical examination. Addressing these obstacles is essential to ensuring virtual care remains an affordable and equitable component of future healthcare.}, }

However, a problem arises when there is hesitancy by economic agents and their dependents, even when the resource is freely available. This policy problem is analyzed in the context of Ghana's major urban area, Accra, where a cross-section of urban parents are surveyed regarding vaccine hesitancy and whether it extends to their children, with special reference to the COVID-19 vaccine.<br><br>METHODOLOGY: Data on preferences of residents regarding the choice for their dependents to receive the vaccine gathered in 2022. The data was obtained through a cross-sectional online survey of 2000 urban parents in Accra, Ghana. The paper estimates logit and probit regression models and their associated marginal effects to examine the willingness of respondents to allow their children to take the vaccine and the extent of influence of attitudinal and demographic characteristics of respondents.<br><br>FINDINGS: The results first show that urban respondents who had tested for COVID-19, taken the vaccine and were willing to pay for the COVID-19 vaccine are more likely to allow their children to take the vaccine. More so, urban respondents concerned about age group vulnerability of their children, not suffering permanently health conditions, and being infected by others are also more likely to allow their children to take the COVID-19 vaccine.<br><br>PRACTICAL IMPLICATIONS: Based on the findings, this paper recommends to policymakers to strengthen education efforts, with special encouragement for parents to get their children vaccinated. Vaccines are meant to provide immunity to the populace and its hesitancy among the population sets back the public health objective of achieving herd immunity and building a robust pharmaceutical industry while increasing the risk of poor public services and higher public health spending.<br><br>ORIGINALITY/VALUE: This paper offers a novel lens on the sustainability of public health expenditure by examining vaccine hesitancy during a pandemic that caught populations unprepared and distrustful. Using evidence from urban Ghana, it shows how reluctance to accept free vaccines reveals the hidden social costs and governance gaps in public health delivery-an overlooked dimension in discussions of health financing in developing countries.}, }

Thus, their dysfunction leads, among others, to the development of autoimmune diseases. In turn, excessive production of TAM receptors correlates with the invasive phenotype of cancer cells, metastasis, drug resistance, and poor prognosis for patients with cancer. Moreover, activation of these receptors contributes to the promotion of an immunosuppressive tumor microenvironment and evading the immune response by cancer cells.

The COVID-19 pandemic has catalyzed revolutionary advancements in vaccinology, particularly through the rapid development of mRNA and viral vector technologies that enable fast and effective immunization against emerging pathogens. This review highlights the progress in these innovative platforms while addressing the multifaceted challenges, including the critical interplay between outbreak dynamics and vaccine development timelines, which result in safety and efficacy profile challenges, disparities in vaccine access for low- and middle-income countries (LMICs), and complex logistical considerations. Despite the potential of cutting-edge approaches such as nanoparticle-based vaccines, integration of artificial intelligence (AI), issues related to immunogenicity, safety, and public trust remain pressing and necessitate immediate attention. The review highlights the urgent need for adaptable regulatory frameworks that can evolve in response to scientific advancements, and underscores the importance of collaborative global initiatives in addressing disparities in vaccine distribution. By integrating insights from these innovative technologies and the challenges they present, this article aims to provide a comprehensive overview of the current landscape in vaccine development, informing future public health strategies and enhancing global preparedness for emerging infectious diseases.}, }

More broadly, the development of RNA-based drugs represents a real paradigm shift with promising therapeutic applications.

At the pharmacological level, the development of RNA-based drugs marks a breakthrough because these drugs can reach previously "undruggable" pharmacological targets. This clearly represents a step toward the possible establishment of personalized treatments for several difficult-to-treat diseases. This review provides an updated, critical, and comprehensive pharmacological analysis of the current RNA therapeutics landscape, including both approved RNA-based drugs and key investigational candidates. We summarize the state of clinical progress, highlighting pharmacological mechanisms, challenges in drug delivery, tolerability, and clinical outcomes. Our comprehensive overview emphasizes the versatility of RNA-based drugs, illustrating their therapeutic application across various diseases such as cancer, neurodegenerative, cardiovascular, metabolic, rare genetic, and infectious diseases. Also, we uniquely explore the concept of RNA-based drugs repurposing, which may leverage shared pathophysiological mechanisms across diseases to accelerate clinical impact.}, }

Relevant research articles that examined risk factors correlated with mental health symptoms among HCWs during the COVID-19 pandemic in the EMRO region were included. We identified 21,126 studies in total. After eliminating 9,554 duplicates, 11,572 studies were screened. Records were excluded if they were from outside EMRO countries (n&#x2009;=&#x2009;11,220), unrelated to HCWs (n&#x2009;=&#x2009;12), lacked full-text access (n&#x2009;=&#x2009;2), or had only abstracts available (n&#x2009;=&#x2009;16).

These studies indicate a high prevalence of mental health problems, including anxiety, depression, and insomnia. Additionally, risk factors such as female sex and younger ages have been identified as being associated with more frequent or severe mental health symptoms. While the findings suggest significant mental health impacts, it is important to recognize that most of the studies are cross-sectional, providing only snapshots of the data. Consequently, future research should aim to explore long-term trends and causal relationships.

In this article we discuss each of these in relation to decisions about public health and social measures (PHSM) during the coronavirus disease 2019 (COVID-19) pandemic and implications for future research. Reliable research evidence of the effects of interventions is particularly important for decisions about what to do because it provides the best basis for estimating the wanted and unwanted effects of doing something. There was little reliable research of the effects of PHSM during the pandemic. For research evidence to be useful to decision-makers, it must be effectively communicated, including how sure we can be about effects or other research findings. Research evidence is essential for making informed decisions, but it is not sufficient. Decision-makers and those affected by the decision must be able to think critically about what to believe and what to do. Many people lack competences and dispositions for thinking critically about PHSM or other interventions. Judgements about PHSM require democratic input, not just expert input. However, there was little public participation in deliberative or decision-making processes about PHSM during the pandemic. There are important uncertainties about the effects of PHSM, how to effectively communicate decisions and evidence about PHSM, how to foster critical thinking about PHSM and how to effectively engage the public in deliberative and decision-making processes about PHSM. Pandemic research and preparedness planning should address those uncertainties.}, }

This scoping review identifies and analyses published peer-reviewed literature on the impact of shocks on patterns of VAW in the Indo-Pacific region between 1993 and 2024. Our review includes 203 studies from 5 databases comprising books, research articles, and chapters. Health emergencies, particularly COVID-19, accounted for the largest portion of shocks studied, followed by armed conflict and earthquakes. The findings indicate that social, political, and environmental events consistently heighten all forms of VAW, especially domestic violence, intimate partner violence, and sexual violence. The review found limited research across the region with 7 countries (of 46) informing the majority of studies: These countries were not necessarily those countries most affected by these events however. Based on these main findings, we argue that localized research on the impacts of these events on VAW is urgently needed to inform gender-responsive policies that can enhance preparedness and protection in the most affected communities.}, }

SARS-CoV-2 infection triggers innate and adaptive immune responses, but excessive cytokine release can drive hyperinflammation, acute respiratory distress syndrome and poor clinical outcomes. Although serological and molecular assays, such as ELISA and RT-qPCR, remain central to COVID-19 diagnostics, they have limited capacity to reveal host-pathogen interactions at the tissue level. Therefore, profiling the human lung proteome offers a powerful strategy to identify molecular signatures associated with viral pathogenesis and disease severity. This review emphasises emerging technologies that advance lung proteome profiling during SARS-CoV-2 infection. Novel strategies include phage display for high-throughput identification of antibody-antigen interactions, yeast two-hybrid for mapping virus-host protein interactions and lateral flow immunoassays for rapid, point-of-care detection. Conversely, omics-based technologies such as single-cell RNA sequencing, microarrays and mass spectrometry are transforming our understanding of the lung proteome by revealing patterns of gene expression, protein abundance and immune heterogeneity. Therefore, comparing these conventional diagnostic assays with innovative approaches, we highlight their unique contributions to lung proteome research. These tools not only improve diagnostic precision but also hold the potential to uncover biomarkers for early risk stratification and therapeutic targeting.

Among these, chronic alcohol consumption represents a clinically significant, yet often under-addressed, vulnerability factor that may exacerbate both the acute severity and long-term consequences of SARS-CoV-2 infection. This narrative review examines the biological and clinical intersections between alcohol use and COVID-19, focusing on shared mechanisms of immune dysfunction, neuroinflammation, and disruption of the gut-brain axis. We synthesize current findings showing that both conditions compromise innate and adaptive immune responses, alter cytokine signaling, and weaken mucosal and blood-brain barriers. These changes contribute to cognitive and emotional dysregulation and may increase the risk of persistent neuropsychiatric symptoms, including those observed in Long COVID. In addition, we discuss how chronic alcohol use may alter host susceptibility to infection and affect the immune response to vaccination, with implications for treatment outcomes and recovery. Our findings highlight the need to integrate alcohol use disorder into COVID-19 risk assessments, clinical management, and long-term mental health care planning. A multidisciplinary approach is essential to address the overlapping biological pathways that link alcohol-related vulnerability to COVID-19 outcomes.}, }

Here, we analyzed cytokine levels in patients with PASC through a systematic literature search of the PubMed/MEDLINE, Web of Science, and Scopus databases, including articles published up to December 2024. A total of 33 studies (comprising 3294 patients) were included, addressing the long-term sequelae following acute Covid-19 infection. Levels of IL-6, IL-2, MCP-1/CCL2, TNF-α, IFN-γ, and IP-10/CXCL10 were higher in Covid-19 patients with PASC compared to those without PASC, suggesting an inflammatory basis for the persistence of symptoms. Conversely, little or no difference was observed for IL-1β, IL-7, IL-10, IL-4, IL-17A, IL-8, and IL-1α. To assess the duration of the sustained inflammatory response post-infection, cytokine measurements were categorized as < 6 months or ≥ 6 months after diagnosis. IL-6, MCP-1/CCL2, TNF-α, and IFN-γ remained elevated in both time windows, while IL-1β, IL-8, IP-10/CXCL10, IL-2, and IL-10 showed increased levels beyond 6 months post-Covid-19 diagnosis.

This variation on a key theme from George Orwell's Animal Farm underscores a significant issue in public health. Ultimately, optimizing public health begins with understanding population health-particularly when assessing the impact of specific health risks that are often intertwined with both benign and malign health determinants. The objective of this contribution is to provide an overview of sources of bias in epidemiological research, drawing inspiration from the work of Rudolph Agricola-Northern Europe's first humanist and a homo universalis. Agricola's methodological approach distinguished between different categories of informational sources, which he deliberately employed as instruments for structured argumentation. This article presents a contemporary variation of that approach in the form of a complementary taxonomy, outlining examples of material and procedural bias sources that, individually or in combination, can affect estimates of mental health problems. These include the nature of the outcome itself and the context of the sample-covering its vulnerability and exposure profile, as well as broader population characteristics-along with data collection methods and analytical techniques. The value of this structured approach to disentangling bias in modern population health research is illustrated with examples from recent studies on the impacts of disasters and the COVID-19 pandemic. Researchers are encouraged to be modest, to carefully consider "locations" or "origins" of bias, and to interpret study findings with caution-especially when using them to inform public health policy or to make arguments about the nature and severity of population health issues.}, }

Since that original publication, COVID-19 and the increased demand for healthcare have presented additional challenges, and staff wellbeing remains an increasing concern. The aim of the FPHC Wellbeing Group was to develop a FPHC Wellbeing Charter, to put the recommendations of the report into practice in a document that outlines achievable measures for all pre-hospital organisations to improve their staff and volunteers' wellbeing.<br><br>METHODS: Questionnaires and focus groups, alongside a literature search and the original FPHC report were utilised to develop the Charter. This was led by the FPHC Wellbeing Group. Participants were sought from a range of pre-hospital organisations including National Health Service ambulance trusts, air ambulance organisations and voluntary organisations such as Mountain Rescue. The Charter has been reviewed by the FPHC Executive Committee.<br><br>RESULTS: Two hundred eighty-one responses to the questionnaire were obtained and six focus groups were held representing the majority of pre-hospital organisations. As a result of this a FPHC Wellbeing Charter has been developed with four main sections: policies for a good organisation; facilities for a good organisation; support for colleagues in a good organisation and continued professional development, study leave and examination support in a good organisation. Within the policies section there are four sub-sections: rotas and rest; illness/return to work; patient outcome follow-up and parental leave (including maternity policies).<br><br>CONCLUSION: The FPHC Wellbeing Charter outlines 'why' and 'how' organisations can take measures to improve their staff and volunteer's wellbeing. Much of the emphasis of the Charter is on reducing secondary stressors by improving simple things, recognising that whilst pre-hospital clinicians and volunteers are often involved in difficult events, daily stresses have a significant cumulative impact. It is anticipated that this will not be a static document; however, a minimum baseline has been set.}, }

This creates an evolutionary trade-off between avoiding infection and maintaining care for sick group members. This narrative review summarizes research using bacterial endotoxin (lipopolysaccharide, LPS) to experimentally induce sickness, focusing on its effects on social behavior in animals and humans. LPS-treated animals generally show reduced social exploration of healthy conspecifics, while healthy conspecifics tend to avoid them. Such avoidance behavior is influenced by environmental factors such as housing conditions, health status, and social hierarchy. Some species, when sick, show a preference for familiar individuals, and exhibit more affiliative, less aggressive behaviors. In humans, LPS-induced sickness leads to heightened sensitivity to both positive and negative social cues, which may reflect an adaptive response to increased vulnerability. Individuals under LPS also demonstrate an enhanced ability to regulate emotional responses and reduced empathy for others' psychological pain, suggesting a shift towards a more self-focused, energy-conserving state. Sick individuals additionally tend to seek care from those with a history of supportive behavior. Humans can detect sickness in others through olfactory and visual cues, such as odor, facial expressions and posture. As observed during the COVID-19 pandemic, prolonged social isolation negatively affects both infected individuals and their caregivers. Future research should therefore investigate the impact of sickness on higher level social cognitive functioning, as well as the role of modulating variables such as familiarity, sickness severity and sample demographics.}, }

However, the integration of nonrandomized studies (NRSs) may be necessary, as was seen during the COVID-19 pandemic due to the emergence of variants of concern. We aimed to examine the body of evidence, randomized and nonrandomized, on COVID-19 vaccine effectiveness (VE) during the emergence of the Delta variant and to share lessons learned from including nonrandomized evidence alongside randomized evidence in the COVID-NMA living systematic review.<br><br>STUDY DESIGN AND SETTING: The COVID-NMA initiative is an international, living systematic review and meta-analysis that continually synthesized evidence on COVID-19 interventions. For this study, we identified all RCTs and comparative NRSs reporting on VE against the Delta variant from December 2020 (its initial detection) through November 2021 (date of last COVID-NMA NRS search). We conducted two parallel systematic reviews: one focusing on RCTs and the other on NRSs to compare available evidence on VE against the Delta variant. We also compared the publication timelines of the included studies with the global prevalence of the Delta variant, and documented the specific methodological challenges and solutions when including NRSs in living systematic reviews.<br><br>RESULTS: From December 2020 to November 2021, only one RCT reported vaccine efficacy against Delta in a subgroup of 6325 participants, while, during the same period, 52 NRSs including 68,010,961 participants reported VE against this variant. Nevertheless, including NRSs in our living systematic review posed several challenges. We faced difficulties in identifying eligible studies, encountered overlapping studies (ie, NRSs using the same database), and inconsistent definitions of Delta variant cases. Moreover, multiple analyses and metrics for the same outcome were reported without a pre-specified primary analysis in a registry or protocol. In addition, assessing the risk of bias required expertise, standardization, and training.<br><br>CONCLUSION: To remain responsive during public health emergencies, living systematic reviews should implement processes that enable the timely identification, evaluation, and integration of both randomized and nonrandomized evidence where appropriate.<br><br>PLAIN LANGUAGE SUMMARY: When new health treatments are tested, the best way to see how well they work is through randomized controlled trials (RCTs).

However, during the COVID-19 pandemic, scientists also had to rely on other types of studies called nonrandomized studies (NRS) based on real-world data because the virus was changing quickly and required urgent action. Our living systematic review examined how effective COVID-19 vaccines were against the Delta variant, which spread widely from late 2020 to 2021. We wanted to understand what both RCTs and NRSs revealed about vaccine protection at that time. We also aimed to learn about the benefits and challenges of including different kinds of studies. From December 2020 to November 2021, we found that only one RCT reported results specifically for the Delta variant, including just over 6000 people. However, during the same period, 52 NRSs, involving over 68 million people, shared results about vaccine effectiveness against Delta in real-world settings. Including these NRSs were important for answering questions quickly, but it also created challenges. For instance, it was sometimes unclear how studies should be included, as many used the same data sources. Different studies defined "Delta cases" in various ways and often reported several kinds of results without stating which one was most significant. Evaluating the quality of these studies was complex and required special training. We developed rules to handle each of these challenges. In this study, we found that while RCTs remain the gold standard, NRSs provided crucial information during a fast-moving public health emergency. To help patients, doctors, and policymakers get timely answers in the future, living systematic reviews should be designed to include both types of evidence when appropriate, using clear methods to address challenges.}, }

It is well known that drugs can be given through various routes of administration, such as the popular oral, subcutaneous, and intravenous routes. It is quite surprising that formulating these same drugs as nanoparticles (NPs) and administering them to the patient could produce better results. Different studies have shown the effects of nanodrug delivery systems in targeting cancer cells, ameliorating pulmonary arterial hypertension, and providing improved treatments for ophthalmic conditions such as glaucoma. In most studies, nanodrug delivery systems have been shown to exhibit targeted action at the desired site or organ, low toxicity, and fewer systemic side effects. These new insights can provide an enhanced understanding of the benefits of NP formulations of drugs, as well as open up new pathways for future creative techniques in addressing emerging medical conditions. Furthermore, these formulations generally consist of polymer- or liposome-based or coated NPs, as they are easily biodegradable, meaning they have a higher ability to disintegrate and, at the same time, are not harmful to living tissues, thereby displaying greater compatibility. New connections can be established through the utilization of NPs in the treatment of emerging diseases worldwide. Data from these studies could provide a foundation for groundbreaking and innovative strategies in coping with or fighting even the recent COVID-19 pandemic.}, }

The main symptoms of patients are cough, fever, diarrhea, etc. In addition, the COVID-19 genome has strong plasticity, and there is a risk of cross-species transmission. The use of western medicine antibiotics brings good therapeutic effects, but also accompanied by many adverse reactions of physical and mental damage. At present, TCM has achieved remarkable results in the treatment of COVID-19. In addition to enriching the cognitive theories of traditional Chinese medicine in the treatment of COVID-19, studies on the cell signal transduction mechanism of TCM in the treatment of COVID-19 have developed rapidly from the perspective of molecular biology. Through literature search, it is found that the occurrence of COVID-19 is closely related to cellular inflammatory response, immune response, apoptosis, proliferation and other physiological and pathological processes. This study systematically elucidates the molecular mechanisms by which traditional Chinese medicine treats COVID-19 by regulating key signaling pathways such as PI3K/Akt, NF-κB, JAK/STAT, and mTOR. It not only effectively alleviates COVID-19 symptoms and suppresses pulmonary inflammation but also reduces complications and drug-related adverse reactions. The integrated traditional Chinese and Western medicine model demonstrates significant synergistic effects in antiviral treatment and overall regulation. Future research should further explore the cross-mechanisms of signaling pathways, strengthen evidence-based medical validation, promote the modernization of traditional Chinese medicine, and provide safer and more effective treatment strategies for global pandemic control.}, }

This research uses a novel technique, the exit meta-analysis, to conclusively update the evidence of HIV's impact on COVID-19-related mortality, hospitalization, and need for Intensive Care Unit (ICU) admission in severe disease. Methods: A search of PubMed, EMBASE, Cochrane Reviews (CDSR), SCOPUS, CINAHL reviews and Google Scholar databases was conducted up to the 18 January 2024 for meta-analyses and observational studies that reported adjusted associations for the effect of HIV on COVID-19 related mortality, hospitalization, and ICU admission. Evidence from existing meta-analyses was summarized narratively, and an updated meta-analysis was carried out using a bias-adjusted inverse variance heterogeneity model. Subgroup analysis was carried out for age groups and geographical regions. Results: Of 3153 records identified, 20 meta-analyses and 56 primary studies, with a total of 27,936,428 participants, including 655,882 PLHIV, were included. A review of the meta-analyses showed conflicting results for all outcomes. In the updated synthesis, HIV was associated with higher odds of mortality (aOR 1.43, 95% CI: 1.01-1.86, I[2] = 90.7%) and ICU admission (aOR 1.49, 95% CI: 0.67-2.30, I[2] = 88.8%), but not hospitalization (aOR 1.11, 95% CI: 0.78-1.48, I[2] = 97.5%). The results for both ICU admission and hospitalization include the null value, leading to lower certainty. The exit meta-analysis suggested conclusive results for mortality (DAts score = -0.012) and hospitalization (DAts score = -0.014), but not for ICU admission. Conclusions: This exit meta-analysis provides conclusive evidence that HIV increases mortality in people with COVID-19; however, more studies may be required to address ICU admission and hospitalization.}, }

In this review, we describe how N-glycosylation of the Fc fragment of the different antibody classes is carried out, and which oligosaccharides are most commonly found in these antibodies. Subsequently, we summarize the biological effects of N-glycosylation of antibodies: on the binding of antibodies to FcRs (which affects various functions, such as antibody-dependent cellular cytotoxicity, antibody-dependent phagocytosis, and the production of pro- or anti-inflammatory chemokines and cytokines), on the ability of antibodies to activate complement and on the ability of some antibodies to directly neutralize the adhesion of bacteria and viruses to host cells (independently of Fab recognition). We describe how the N-glycosylation profile of antibodies is modified during certain infections (such as tuberculosis, COVID-19, influenza and dengue) and in response to vaccination, and the potential use of this profile to identify the stage and severity of an infection. Finally, we review the importance of N-glycosylation for the pharmacokinetic, pharmacodynamic and safety profiles of therapeutic monoclonal antibodies.}, }

Information searches from online databases and supplementary sources identified 20 articles that met criteria. Student perceptions indicate that these alternative placements supported the learning of interprofessional collaboration competencies. Outcomes mapped against the updated Canadian Interprofessional Health Collaborative Competency Framework indicate that the most frequently reported interprofessional collaboration competency was team communication and the least reported were collaborative leadership and team differences/disagreements processing. Although gains in interprofessional collaboration competencies were reported across the studies, their methodological shortcomings make it difficult to determine whether alternative placements (e.g. online and telephone-based) were better or comparable to traditional placements (i.e. with face-to-face interactions), for interprofessional collaboration competency development. These findings suggest the need for further research assessing the effectiveness and sustainability of alternative placement models.

To improve their stability and extend shelf life, recent studies have been devoted to converting liquid formulations into solid forms using drying technology. Among them, freeze-drying (lyophilization) is an effective strategy that freezes samples and removes moisture through primary (sublimation) and secondary (desorption) drying stages, maximally preserving the structural integrity and biological activity of mRNA vaccines. The significant reduction in moisture content effectively inhibits the rate of hydrolysis of mRNA, which is considered the primary factor contributing to the instability of mRNA vaccines. However, the freeze-drying process itself and its accompanying stresses pose key challenges, involving many critical variables closely related to formulation composition, process parameters, and manufacturing environment. This paper systematically reviews the application of different freeze-drying technologies in mRNA vaccines and the optimization strategies of lyophilized mRNA vaccines, aiming to provide theoretical foundation and guidance for optimizing freeze-drying processes, enhancing vaccine stability and expanding their application scope.}, }

Patients often face individual challenges in dental care. Why patients decide for or against dental treatments can be determined by many factors, e.g., their own financial resources, preferences, and external circumstances. This cross-country study aims to identify those factors.<br><br>METHODS: We systematically searched for literature in the biomedical databases PubMed (including MEDLINE), the Cochrane Library, and Web of Science to identify factors influencing dental treatment decisions across different countries. Factors of choice were extracted from relevant articles to develop a codebook for subsequent qualitative analysis using an inductive thematic analysis approach. Study quality was assessed using the Mixed Methods Appraisal Tool (MMAT). This systematic review followed the guidelines of the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) and the Synthesis Without Meta-analysis (SWiM) statements.<br><br>RESULTS: After multistage screening of N&#x2009;=&#x2009;4,226 publications by two reviewers, N&#x2009;=&#x2009;233 relevant articles of different study designs (qualitative (N&#x2009;=&#x2009;42), quantitative (N&#x2009;=&#x2009;177), and mixed-methods (N&#x2009;=&#x2009;14)) were included in the analysis. Data collection was realized across different settings (e.g., dental practices (N&#x2009;=&#x2009;18)) and approaches (e.g., interviews) in 49 countries. Included articles focused on specific treatments (e.g., caries treatment) or treatments in general (e.g., dental tourism). Across the countries, various factors of choice (n&#x2009;=&#x2009;101) were identified, divided into three categories: (I) "Dentist &amp; dental institution" (e.g., communication), (II) "Patient" (e.g., dental fear), and (III) "Treatment" (e.g., durability). The factors 'out-of-pocket payment' and 'dental fear' were identified in most of the articles (N&#x2009;=&#x2009;136, N&#x2009;=&#x2009;64) and were mentioned most frequently (code frequencies: n&#x2009;=&#x2009;151, n&#x2009;=&#x2009;73).

Frequency of the factor 'dental fear' varied by country. One publication addressed the COVID-19 pandemic. It reported that treatment appointments were postponed and canceled by patients due to their fear of infection with SARS-CoV-2. The quality of the included studies varied considerably.<br><br>CONCLUSIONS: A range of factors influence patients' choice regarding dental treatments. Understanding patients' motivation for seeking dental care can guide the development of interventions (e.g., awareness campaigns and health literacy efforts) that support proactive dental care.

In 2020, we hypothesized that adipose tissue (AT) might serve as a viral reservoir and amplifier of immune responses in SARS-CoV-2 infection. Five years on, accumulating evidence supports this hypothesis. Recent autopsy and in vitro studies support that SARS-CoV-2 disseminates to and may replicate within human adipocytes. While several studies have detected SARS-CoV-2 RNA and proteins in AT, the recovery of infectious virus from this tissue has not yet been demonstrated. This remains a critical gap in our understanding of SARS-CoV-2 viral tropism and replication within adipocytes. Viral entry is mediated via angiotensin-converting enzyme-2 and neuropilin-1 receptors. Infected AT exhibits immune cell infiltration and cytokine activation, implicating it in systemic inflammation. Persistent viral RNA in AT correlates with prolonged metabolic dysfunction. These findings highlight the dual role of AT as a potential viral reservoir and immunometabolic organ. Understanding these mechanisms is critical to mitigating the long-term impact of COVID-19 and guiding responses to future pandemics involving metabolically active tissues.}, }

CCP was successfully deployed in both resource-poor and resource-rich countries, establishing that convalescent plasma (CP) is a feasible option for combating the next pandemic. CCP reduced mortality and progression to hospitalization when used early in the disease with high-titer units. This knowledge was gained from a worldwide effort that included more than 50 countries. However, the deployment of CCP was haphazard and varied among countries. Clinical studies suffered from a lack of standardization regarding study design, CCP antibody dosing, timing of administration, and participant disease severity. Unfortunately, the hard-won knowledge from the serum therapy era in the early 20th century, which indicated that effective antibody therapy requires early use in the disease with a sufficient antibody dose, was largely forgotten. Many studies tested CCP late in the disease or without sufficient antibody titer and thus reported negative findings. Trial heterogeneity made it difficult to combine the results of studies. However, despite tremendous heterogeneity in study design and participant populations, meta-analysis revealed strong signals of efficacy when given early with high antiviral-specific antibody levels. When the next pandemic occurs, humanity is likely to resort to CP again. To avoid another chaotic rollout, planning for CP use should begin well before that emergency arrives and must involve both physician education on the principles of antibody therapy and clinical trial designs that test its efficacy in optimal conditions, which include early use with sufficient antibody doses.}, }

The COVID-19 pandemic disrupted more than three-quarters of CR programs worldwide, exposing deep-rooted limitations in access, infrastructure, and delivery models. At the same time, the pandemic served as a catalyst for innovation. Rapid implementation of virtual, home-based, and hybrid models demonstrated that CR could be delivered flexibly and effectively beyond traditional settings. This review synthesizes emerging evidence and policy responses, highlighting opportunities to modernize CR delivery while embedding equity, patient-centeredness, and digital innovation into routine care. We conclude that the future of CR must be inclusive, technology-enabled, and integrated into the broader continuum of preventive care.

We conducted a systematic review with meta-analysis and trial sequential analysis (TSA) of clinically relevant outcomes from randomized controlled trials (RCTs) of molnupiravir for treatment of nonsevere COVID-19 in adults.<br><br>METHODS: We searched for publications of RCTs of molnupiravir for nonsevere COVID-19 in appropriate bibliographic databases up to 1 February 2025. We pooled appropriate data utilizing an inverse variance, random-effects model, with results expressed as relative risk (RR) with associated 95% confidence intervals (CIs), and statistical heterogeneity between pooled estimates calculated using the I[2] statistic. We appropriately conducted risk of bias assessment for the included RCTs and graded the quality of pooled evidence for each outcome using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach.<br><br>RESULTS: Out of 680 screened literature citations, nine RCTs involving a total of 30,971 patients met the eligibility criteria for inclusion in this review. The majority (78%) of these RCTs were of a low risk of bias. We determined that there was more viral clearance with molnupiravir treatment compared with placebo or no treatment (RR 1.08 [95% CI 1.01-1.16], I[2] 40.8%, five RCTs, 1785 patients, moderate quality evidence) and that treatment with molnupiravir did not reduce the risk of hospitalization (RR 0.73 [95% CI 0.47-1.14], I[2] 58.3%, five RCTs, 28,626 patients; high quality evidence), and all-cause mortality (RR 0.51 [95% CI 0.15-1.69], I[2] 36.8%, four RCTs, 27,445 patients; high quality evidence). We also determined that molnupiravir did not increase adverse or serious adverse reactions. However, TSA suggested more RCTs should be conducted before any conclusions can be reached for viral clearance, all-cause mortality, and adverse reactions, but that further RCTs on the risk of hospitalization and serious adverse reactions may not be needed.<br><br>DISCUSSION: Notwithstanding a paucity of RCTs, our findings suggest that molnupiravir may only be efficacious for clearance of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2; the virus responsible for COVID-19) in adults with nonsevere COVID-19 although the evidence is not sufficient for conclusions to be drawn.

Furthermore, the Coronavirus Disease 2019 (COVID-19) pandemic and subsequent reported ocular diseases have fundamentally changed the landscape of VIOD epidemiology and management. Epidemiological data indicate heterogeneous effects on common infections such as Adenoviral conjunctivitis due to varying compliance with hygiene measures. Concurrently, systemic immunological events, notably those induced by COVID-19 infection or certain vaccinations, have been linked to the reactivation of latent Alphaherpesviruses, including Herpes Simplex Virus (HSV) and Varicella Zoster Virus (VZV). The metagenomic next-generation sequencing (mNGS) offers a significantly improved diagnostic yield (up to 92.7 % in some cohorts) for complex infectious keratitis compared to conventional methods, providing an unbiased tool crucial for timely, targeted treatment. Therapeutic challenges are defined by the persistent threat of antiviral resistance, primarily driven by mutations in the viral Thymidine Kinase (TK) gene. To overcome poor ocular bioavailability, novel drug delivery systems (NDDS), such as Acyclovir-loaded Niosomes and Cubosomes, show promise by enabling sustained drug release and enhanced corneal permeation. Effective future VIOD control requires a multi-pronged strategy integrating robust global surveillance, rapid deployment of advanced molecular diagnostics, and the clinical implementation of resistance-beating therapies delivered via optimized nanocarrier platforms.

Gaining a better understanding of trialists' experiences of adapting interventions for remote delivery will identify where more in-depth investigation and guidance is needed.<br><br>METHODS: The Joanna Briggs Institute (JBI) scoping review guidelines were followed. The search was developed for MEDLINE and adapted for Web of Science, PsycINFO, EMBASE, and Cochrane. Data were extracted on study characteristics, methods reported to adapt interventions, and the challenges and facilitators of the process of adaptation and remote intervention delivery. Data on remote intervention delivery were organised using the upper level of the Behaviour Change Intervention Ontology.<br><br>RESULTS: Fifteen articles were eligible for inclusion describing insights from 16 randomised controlled trials, across a range of populations and trial designs. Most discussion focused on challenges and facilitators of the remote delivery of the complex intervention. These included privacy and safety concerns of intervention delivery within the home setting, and technological issues of remote delivery via video call. The most frequently reported facilitator was the use of an environmental inventory before intervention delivery to check the space in which participants were located, and the materials available to them.<br><br>CONCLUSION: Suitability of an intervention for remote delivery depends not only on whether it is originally delivered via a digital technology, but also the extent to which it requires human facilitation and support.

This review highlights the significance of IL-37 in common respiratory diseases. Specifically, IL-37 can alleviate asthma by inhibiting Th2/Th17 immune responses, inhibiting the release of epithelial-derived alarmins (TSLP and IL-33), and attenuating airway remodeling. In pulmonary infections, IL-37 modulates host responses by mitigating virus-induced hyperinflammation and inhibiting viral replication, as observed in COVID-19 and influenza, while also regulating immunopathology in Mycobacterium tuberculosis and fungal infections. Moreover, in non-small cell lung cancer (NSCLC), IL-37 directly suppresses tumor proliferation and migration, and restrains tumor progression through immunomodulation and angiogenesis regulation. In pulmonary fibrosis, IL-37 reduces collagen deposition and promotes autophagy, thereby counteracting interstitial fibrosis. Collectively, these findings demonstrate that IL-37 serves as a crucial immunomodulator in respiratory diseases, and targeting IL-37 offers novel insights and strategic opportunities for clinical intervention. This review systematically summarizes the molecular mechanisms of IL-37 and discusses its clinical therapeutic potential.}, }

The growing number of models describing individual signaling pathways poses the challenge of integrating them into a cohesive framework. This review aims to identify common components across existing ordinary differential equation models that could serve as key nodes to merge distinct signaling modalities. Proposed models highlight Bcl-2, Bax, Ca[2], and p53 as shared regulators linking autophagy and apoptosis. Necroptosis and apoptosis are interconnected via TNF signaling network and modulated by caspase-8, c-FLIP, and NFκB, with RIPK1 acting as a critical hub directing pathway choice. Pyroptosis and apoptosis are co-regulated by NFκB, tBid, and caspases, while ferroptosis is modeled exclusively as an independent process, separate from other forms of cell death. Furthermore, existing models indicate that ICD intersects with necroptosis during oncolytic virotherapy, with pyroptosis in SARS-CoV-2 infection, and with apoptosis in the context of chemotherapy. Although several models address crosstalk between pairs of cell fate decisions, creating comprehensive frameworks that encompass three or more death modes remains an open challenge.}, }

This may include data from in vitro neutralization testing, real-world studies, and clinical pharmacology studies. There are various clinical pharmacology approaches available to aid in dose selection of COVID-19 mAbs, and the approach used for initial dose selection may differ from that used to justify dose modifications in light of new variants. At present, there is no universally accepted approach that has been shown to work in all circumstances, and most of the available methods lack validation against clinical data.

While its public health benefits are unequivocal, the unprecedented scale of vaccination-reaching billions worldwide-has also enabled the detection of rare autoimmune events, including systemic lupus erythematosus, rheumatoid arthritis, type 1 diabetes, and Guillain-Barré syndrome. Although such events occur in only a small subset of individuals, often influenced by genetic, environmental, or dosage-related factors, they underscore the importance of understanding immune tolerance mechanisms in vaccination. This review synthesizes clinical observations and immunological findings from the COVID-19 vaccination era, highlighting key mechanisms such as molecular mimicry, adjuvant-induced inflammation, bystander activation, epitope spreading, and polyclonal B cell activation. We also consider how novel vaccine platforms, particularly mRNA-based technologies, may influence immune regulation and self-tolerance. Importantly, we discuss the therapeutic management of vaccine-associated autoimmunity, including the use of corticosteroids, intravenous immunoglobulin (IVIG), plasma exchange, disease-modifying anti-rheumatic drugs (DMARDs), and other immunosuppressive agents, many of which have led to favorable clinical outcomes. By integrating mechanistic insights with treatment strategies, this review emphasizes that the overall benefits of COVID-19 vaccination overwhelmingly outweigh the risks, while advocating for continued surveillance, mechanistic research, and risk stratification to inform safer and more targeted vaccination strategies in future pandemics.}, }

The SARS-CoV-2 pandemic brought unprecedented challenges, emerging in the context of extreme globalization and rapid technological development. The speed of viral spread, the highest absolute mortality rate caused by a viral agent in the last 100 years, and the severe economic and social consequences imposed an urgent need for vaccine development on a previously unimaginable timescale. The proven safety and efficacy of inactivated vaccines enabled the development and large-scale application of the first immunizer against SARS-CoV-2 in less than a year after the World Health Organization (WHO) declared the pandemic. In this review, we discuss the importance of inactivated antiviral vaccines and their historical impact in containing highly harmful diseases affecting humanity. We also explore the cellular mechanisms by which inactivated vaccines may induce immunogenic responses against viral pathogens. In addition, we bring to light a discussion about a fast, cost-effective, potentially efficient technology for large-scale immunizer production: High hydrostatic pressure (HHP), a method long supported by decades of preclinical studies and which is especially effective in the context of enveloped viruses. Finally, we discuss the role of inactivated antiviral vaccines in the face of advances in biotechnology and, therefore, the emergence of vaccines that use genetic engineering in their production, such as RNA, DNA and viral vaccines, which have gained special prominence during the COVID-19 pandemic.}, }

Although clinical manifestations are typically mild, these HCoVs exhibit ongoing antigenic drift and have demonstrated the potential to cause severe diseases in certain populations, underscoring the importance of developing targeted and broad-spectrum vaccines. This review systematically examines the pathogenesis, epidemiology, genomic architecture, and major antigenic determinants of seasonal HCoVs, highlighting key differences in receptor usage and the roles of structural proteins in modulating viral tropism and host immunity. We summarize recent advances across various vaccine platforms, including inactivated, DNA, mRNA, subunit, viral-vectored, and virus-like particle (VLP) approaches, in the development of seasonal HCoV vaccines. We specifically summarize preclinical and clinical findings demonstrating variable cross-reactivity between SARS-CoV-2 and seasonal HCoV vaccines. Evidence indicates that cross-reactive humoral and cellular immune responses following SARS-CoV-2 infection or vaccination predominantly target conserved epitopes of structural proteins, supporting strategies that incorporate conserved regions to achieve broad-spectrum protection. Finally, we discuss current challenges in pathogenesis research and vaccine development for seasonal HCoVs.

Using PRISMA guidelines and the PICOS framework, searches across four databases identified 325 articles published between 2010 and 2025, of which 56 (17%) were included for analysis. Thematic synthesis revealed key trends, disease priorities, and surveillance tools. South Africa contributed the highest number of articles (25%), while Sub-Saharan Africa accounted for 54% overall. COVID-19 was the most frequently studied disease (20%), followed by cholera, typhoid, and measles. The Integrated Disease Surveillance and Response (IDSR) framework appeared in 25% of articles, while District Health Information Systems 2 (DHIS2) was referenced in 11%, reflecting modest adoption of digital platforms. Reported challenges included underreporting, inconsistent case definitions, limited digital infrastructure, and weak feedback mechanisms. Although integration of environmental health was widely recommended, it was marginally implemented. Overall, LMICs surveillance systems remain constrained by operational and structural limitations, underscoring the need for digital investment, environmental indicators integration, and community-based approaches to strengthen epidemic preparedness.}, }

SARS-CoV-2 is a particularly severe threat in this population and COVID-19 is associated with higher rates of hospitalization and mortality compared to immunocompetent individuals. Vaccination remains the most effective preventive method. However, immune responses to vaccination in cancer patients are often heterogeneous and weaker than in healthy populations. While booster doses can improve the protection, vaccine effectiveness wanes over time, and some patients may not respond well, with significant variability across cancer types, cancer status and treatment regimens. These observations highlight the importance of more personalized vaccination strategies informed by a thorough understanding of immune correlates of protection, including humoral, cellular, and mucosal immunity. Assessing different layers of immunity requires different experimental approaches, robust assay standardization and data harmonization.

Children and young people are disproportionally challenged in number and severity, which may be explained by the large proportion of genetic conditions among rare diseases (70%-80%). Indeed, an estimated 30% of children with rare diseases do not survive past their fifth birthday. Because rare diseases are frequently missed or diagnosed with a delay of several years and <5% of rare diseases have a licensed treatment, the impact of rare diseases on the indivual affected (independent of age) and wider society is significant. To address these challenges sufficiently, rare disease expert centers combining research activity with patient care are needed to develop diagnostic tests, prognostic tools, and new treatments. This expert-driven approach promises expedited diagnosis and efficacious treatment and care. Although restricted by chronic underfunding, rare disease research keeps delivering new exciting treatment options and technologies, some of which have revolutionized care not only in niche areas of medicine but also common diseases (the use of interleukin-1 blockers in gout or COVID-19-associated hyperinflammation, etc). However, rare disease research and care will only be successful in collaborative, mutidisciplinary and multiprofessional teams that involve patients and families as equal partners and span across institutional and national borders.

Despite their increasing adoption, there is limited systematic evidence evaluating the effectiveness, implementation strategies, and policy implications of social prescriptions in the Korean context.<br><br>METHODS: This study conducted a scoping review of the literature related to social prescriptions in Korea. English- and Korean-language articles were retrieved from five databases (Google Scholar, Web of Science, PubMed, Scopus, and KCI) without time restrictions. The studies were screened and selected based on predefined criteria. Machine learning-based topic modeling (LDA, NMF, and BERTopic) was applied to extract the latent thematic structures from the included studies. The evaluation metrics included coherence score, perplexity, topic diversity, and topic balance-guided model selection. The NMF model was selected for final analysis because of its superior performance.<br><br>RESULTS: Six key thematic categories were identified from 16 studies: (1) Mental Health, (2) evaluation, (3) program, (4) Social Issues, (5) COVID-19, and (6) international comparisons. Mental health and social isolation have emerged as major concerns, particularly in aging rural populations. Programs focusing on gardening, music, and digital platforms have been reported to be effective in improving psychological wellbeing and community engagement. The analysis also highlights the necessity of localized models tailored to Korea&#x2019;s demographic and policy landscape.<br><br>CONCLUSIONS: This study emphasized the need for a comprehensive policy framework for social prescriptions in South Korea. The integration of digital technology for remote delivery, adaptation to rural health gaps, and benchmarking from established international models is recommended.

Among them, the Omicron variant (B.1.1.529) and its sublineages BA.2.75, JN.1.8, and KP.2 have shown enhanced transmissibility and immune evasion, while generally exhibiting reduced lower respiratory tract pathogenicity compared to earlier variants, thereby continuing to pose significant challenges to public health. In India, these variants have significantly shaped the trajectory of the pandemic, necessitating focused evaluation of their biological and clinical impact. This review aims to provide a comprehensive study on the virology, pathophysiology, and systemic manifestations of Omicron and its emerging subvariants upto July 2025. We discuss their mechanisms of entry and replication, interaction with ACE2 and TMPRSS2 receptors, and evasion of host immune responses. Particular emphasis is placed on multi-organ involvement beyond the respiratory system, including neuro-respiratory dysregulation, cardiovascular complications, hepatic injury, gastrointestinal disturbances, and renal dysfunction. Furthermore, we evaluate the effectiveness of available vaccines, antiviral therapies, and diagnostic tools, alongside emerging clinical strategies such as vagus nerve stimulation, thermal modulation, and respiratory muscle training. By integrating molecular insights with clinical outcomes, this review highlights the multifaceted and systemic nature of Omicron-induced disease. We underscore the urgent need for variant-specific immunisation, early intervention strategies, and robust genomic surveillance to mitigate long-term sequelae and guide preparedness for future outbreaks.}, }

Methods: The study was guided by an integrated Patient-Provider Partnership, Engagement, and Collaboration (PEC) framework that influenced patient-provider interaction during the provision of SDOH services. A qualitative study design was applied, and eight quality improvement interviews with healthcare providers were conducted to understand the existing community and health service system context. Six in-depth interviews were conducted with Mandarin-speaking Chinese American caregivers. Interviews were transcribed and coded in Mandarin and then translated into English. Results: Consistent with the PEC framework, we identified cognitive, affective, and communication gaps from both the patient and provider. Caregivers reported unaddressed needs in food, financial security, and mental health. Providers identified gaps in patient workflow, staffing, and the intake form process. Conclusions: Addressing social determinants of health among Chinese American immigrant populations is crucial for mitigating poor health outcomes in children and families. Multi-level community-engaged strategies are needed to alleviate the challenges facing this community. Recommendations for future research should consider the importance of language and cultural affinity, digital intake forms translated into the patient's language, and regular on-site staffing during SDOH screenings.}, }

Valued at approximately USD 53 billion in 2024 and projected to nearly double by 2033, the global POC diagnostics market is driven by infectious disease assays and accelerated by innovations in molecular amplification, biosensors, microfluidics, and artificial intelligence (AI). This review integrates current evidence across technological, clinical, regulatory, and public health domains. Immunoassays remain the backbone of volume deployment, while molecular nucleic acid amplification tests (NAATs) and emerging CRISPR-based platforms achieve laboratory-grade sensitivity at the point of care. AI has transitioned from an experimental tool to an embedded analytical layer that enhances image interpretation, multiplex signal deconvolution, and automated quality control. Rigorous validation, including analytical accuracy, clinical performance in intended-use settings, and usability testing under CLIA guidance, remains central to ensuring reliability in decentralized environments. Regulatory frameworks are adapting in parallel: FDA's lifecycle oversight of AI-enabled devices, the European IVDR's expanded evidence requirements, and the WHO Prequalification all emphasize continuous post-market surveillance. From a public health perspective, POC diagnostics have improved early case detection, treatment initiation, and outbreak containment for HIV, tuberculosis, malaria, influenza, RSV, and COVID-19. Yet persistent challenges (including limited harmonization of standards, uneven reimbursement, and scarce real-world data from low- and middle-income countries) continue to constrain equitable adoption. POC infectious disease diagnostics are thus entering a pivotal phase of digitization and regulatory maturity. Addressing remaining gaps in validation, lifecycle monitoring, and implementation equity will determine whether these technologies achieve their full promise as clinical accelerators and as cornerstones of global infectious disease preparedness.}, }

Yet, criteria separating benefit from futility remain fragmented. Objective: This paper seeks to map contemporary evidence (2015-2025) on outcomes after Intensive Care Unit (ICU) admission in adults with cancer and to identify clinical constellations in which ICU-level care still changes prognosis. Methods: PRISMA-ScR scoping review (PCC framework). PubMed search (2015-2025), dual screening, standardized extraction; narrative/thematic synthesis across six clusters (hematologic, solid tumors, sepsis/non-COVID-19 infection, COVID-19/viral pneumonia, novel/targeted-therapy toxicities, end-of-life/aggressive ICU) were used. No meta-analysis given heterogeneity. Results: Seventy-three studies (>170,000 ICU admissions) were included, mostly cohort designs across 27 countries. ICU mortality ranged 8-72% (weighted mean ≈ 41%); hospital ≈ 38%; 90-day ≈ 46%; 1-year ≈ 62%. About one third of ICU survivors resumed systemic therapy. Benefit concentrated in early admissions, single-organ failure, controlled/remission disease, postoperative/elective monitoring, and reversible treatment-related toxicities (e.g., ICI pneumonitis, CAR-T CRS/ICANS). Futility clustered around ≥3 organ supports, RRT > 7 days, refractory/progressive disease, and ECOG ≥ 3. Sepsis outcomes averaged 45-55% ICU mortality but improved with rapid recognition and source control; COVID-19 mortality was particularly high in hematologic malignancies early in the pandemic, with subsequent declines post-vaccination. Conclusions: In modern oncologic practice, ICU care changes prognosis when the acute physiological insult is reversible and cancer control remains plausible; conversely, high organ-support burden and refractory disease define practical futility thresholds. These signals support time-limited ICU trials, earlier ICU involvement for sepsis/irAEs, and embedded palliative care to align intensity with goals.}, }

To overcome this, developing broad-spectrum nAbs that target the conserved S2 subunit of the spike protein is crucial. Unlike the highly mutable RBD, the S2 region remains structurally conserved, providing a promising foundation for universal protection.

By cleaving polybasic motifs within viral glycoproteins, furin enables the maturation of structural proteins essential for viral entry, fusion, and replication. This mechanism has been documented across a broad spectrum of human pathogens, including SARS-CoV-2, influenza virus, human immunodeficiency virus, human papilloma virus, hepatitis B virus, flaviviruses, herpesviruses, and paramyxoviruses, highlighting furin as a conserved molecular hub in host-virus interactions. Genetic variability within the FURIN gene further modulates infection outcomes. Several single-nucleotide polymorphisms (SNPs), such as rs6226 and rs1981458, are associated with altered COVID-19 severity, whereas variants like rs17514846 confer protection against human papilloma virus infection. Conversely, mutations predicted to reduce enzymatic activity have been linked to attenuated SARS-CoV-2 pathogenesis in certain populations. These findings underscore the importance of considering population genetics when evaluating viral susceptibility and disease progression. Despite advances, unresolved questions remain regarding furin's non-canonical roles in viral life cycles, tissue-specific regulation, and interactions with other host proteases and immune modulators. Targeted inhibition of furin and related convertases represents a promising avenue for broad-spectrum antiviral interventions. Collectively, current evidence positions furin as a central node at the intersection of viral pathogenesis, host genetic variability, and translational therapeutic potential.}, }

Eight patient themes (including symptom burden, identity disruption and stigma) and four professional themes (including recognition, care coordination and holistic care models) were identified. Recognition emerged as a cross-cutting mechanism: validation and consistent pacing guidance facilitated engagement and safer activity, whereas invalidation and inconsistent advice were associated with distress, avoidance, and disengagement. Trajectories showed gradual expansion of multidisciplinary care models, but major capacity and equity gaps persisted. Most studies had low methodological concerns, although heterogeneity in populations and settings was substantial.<br><br>INTERPRETATION: Long COVID is a chronic, biological condition that also intersects with social and psychological dimensions, and may present with episodic, continuous, or progressive trajectories.

This is postulated to be driven by systemic inflammation, endothelial activation and contact activation of the coagulation cascade due to extracorporeal circulation. However, the coronavirus disease 2019 (COVID-19) pandemic revealed a unique hypercoagulable state, termed COVID-19-associated coagulopathy (CAC), also observed in those vaccinated against COVID-19. CAC displays similar physiological manifestations to those of disseminated intravascular coagulation (DIC), characterised by elevated fibrinogen and D-dimer values. The precise pathogenesis of CAC requires further elucidation though proposed mechanisms include: an exaggerated inflammatory response to COVID-19 infection or antibody proliferation due to vaccination, direct epithelial cell damage mediated by angiotensin converting enzyme 2, and 'hypoxithrombosis'. CAC has since provided a unique framework to understand and potentially mitigate coagulation complications encountered during CPB in the post-pandemic era, as it is no longer sufficient to view COVID-19 as a transient influence on surgical risk. Rather, it must be recognized as a persistent modifier of the haemostatic environment across the population, with direct implications upon patient selection, intraoperative management and postoperative care in cardiac surgery. This review examines the pathological drivers behind CAC alongside the insights obtained from CAC management during ECMO deployment, to investigate the potential translation of such knowledge into improved anticoagulation strategies and monitoring during cardiac surgery. The use of alternative anticoagulants including factor XI inhibitors and the modulation of heparinase activity offers promising avenues to attenuate coagulopathies more commonly observed during CPB in the post-pandemic climate, whilst anti-Xa assays and viscoelastic testing have offered applicability to modern perfusion practices. By bridging the knowledge gained during the pandemic with that of conventional CPB, this review aims to inform future strategies for haemostasis management in cardiac surgery in a novel cohort of surgical patients.}, }

A narrative review of experimental and clinical studies investigating ten TLRs in the context of the pulmonary vascular microenvironment and viral infections. Activation of TLR1/2, TLR4, TLR5/6, TLR7/8, and TLR9 converges on the MyD88-NF-κB/IL-6 axis, thereby enhancing endothelial-mesenchymal transition, smooth muscle proliferation, oxidative stress, thrombosis, and maladaptive inflammation, ultimately increasing pulmonary vascular resistance. Conversely, TLR3, through TRIF-IFN-I, preserves endothelial integrity and inhibits vascular remodeling; its downregulation correlates with PAH severity, and poly (I:C) restitution has been shown to improve hemodynamics and right ventricular function. HIV-1, EBV, HCV, endogenous retrovirus K, and SARS-CoV-2 infections modulate TLR circuits, either amplifying pro-remodeling cascades or attenuating protective pathways. The "TLR rheostat" is shaped by polymorphisms, ligand biochemistry, compartmentalization, and biomechanical forces. The balance between MyD88-dependent signaling and the TRIF-IFN-I axis determines the trajectory of PAH. Prospective therapeutic strategies may include TLR3 agonists, MyD88/NF-κB inhibitors, modulation of IL-6, and combination approaches integrating antiviral therapy with targeted immunomodulation in a precision approach.}, }

This review examines the epidemiology, transmission pathways, and mechanisms of microorganisms of public health importance (bacteria, fungi, parasites, and viruses). It highlights the interconnectedness of ecosystems, where the environment plays a central role in the dissemination of pathogens, driven by climate change, globalization, agricultural intensification, and habitat degradation. AMR is a major concern, driven by the indiscriminate use of pharmaceuticals in human, veterinary, and agricultural settings, horizontal gene transfer through mobile genetic elements, and microbial evolution. The study of different pathogens is of great importance due to their high prevalence in different ecosystems, their virulence, clinical interest, and mortality rates produced. Some of them are ESKAPE bacteria, Candida auris, Plasmodium falciparum, and emerging viruses such as SARS-CoV-2, which present complex transmission dynamics influenced by ecological and health determinants. The review also addresses the effects of climate change on the persistence and geographic spread of pathogens. Successful implementation of the One Health program requires intersectoral policies, integrated surveillance systems, prudent use of antimicrobials and investment in translational science. Coordinating these strategies is essential to limit the spread of pathogens, protect biodiversity, and save global health in the face of the growing threat of infectious diseases.}, }

Sequential and simultaneous co-infections exacerbate disease severity, leading to acute respiratory distress syndrome (ARDS), prolonged hospitalization, and increased mortality. Molecular and immunological interactions are complex, context-dependent, and largely unknown. Experimental models of infection that accurately mimic human respiratory physiology are required for the study of viral dynamics, virus-virus interactions, and virus-host interactions. This review outlines a range of complex in vitro and ex vivo models, including organoids, air-liquid interface cultures, lung-on-a-chip platforms, and in vivo animal models, highlighting their ability to simulate the complexity of respiratory co-infections and their limitations. The field has developed significantly, despite challenges like variability across viral strains, timing of infection, and non-standardization of models. Integration of multi-omics technologies and application of highly translational models such as non-human primates and lung-on-a-chip technology are promising avenues to uncover the molecular determinants of co-infection and guide development of targeted therapeutic strategies. Interrelatedness of experimental models and clinical outcomes is highly critical to improve prevention and treatment of respiratory viral co-infections mainly among high-risk populations.}, }

SARS-CoV-2 infection is associated with significant alterations in gut microbial composition, disturbing its homeostasis and promoting a reduction in the abundance of beneficial symbiotic bacteria and an increase in the abundance of opportunistic pathogens. Furthermore, the composition of the gut microbiota may play a role in the prognosis of patients with post-COVID-19 infection. The microbiota of the intestinal tract and the respiratory tract influence each other; therefore, the gut-lung axis has attracted increasing interest in understanding COVID-19. Moreover, the brain-gut axis has been studied, since there have been reports of anxiety and depression along with post-COVID-19 gastrointestinal symptoms. Treatments options for intestinal dysbiosis in Long-COVID patients include probiotics, prebiotics, and fecal microbiota transplantation. These treatments may serve as an approach to improve gastrointestinal symptoms during Long-COVID, increasing microbiome diversity, strengthening the integrity of intestinal barrier functions, and consequently influencing the treatment of COVID-19.}, }

This narrative review explored the literature and structured relevant findings in three key dimensions: (i) the structural and operational limitations of existing surveillance systems for the WHO priority diseases in resource-limited settings including challenges in data integration, laboratory capacity, workforce, and community engagement; (ii) how these surveillance gaps could delay detection and hinder the response to future emerging threats, particularly a hypothetical but inevitable Disease X; and (iii) innovative and context-adapted strategies to strengthen epidemic intelligence including integrated One Health surveillance, digital and genomic tools, participatory approaches, and regional data-sharing mechanisms. We argue that building agile, equity-centered, and decentralized surveillance systems is not only essential for managing known threats, but also foundational to the early detection and rapid containment of the next public health emergency in resource-limited settings. This review uniquely frames surveillance limitations in resource-limited settings as a global security concern and outlines context-adapted, equity-centered innovations to strengthen epidemic intelligence in preparation for Disease X.}, }

These crises exposed the weaknesses of traditional diagnostic models, including long turnaround times, uneven resource distribution, and supply chain bottlenecks. As a result, there is an urgent need for more advanced diagnostic technologies and integrated diagnostics strategies. Our review summarizes key lessons learned from four recent major outbreaks and highlights advances in diagnostic technologies. Among these, molecular techniques such as loop-mediated isothermal amplification (LAMP), transcription-mediated amplification (TMA), recombinase polymerase amplification (RPA), and droplet digital polymerase chain reaction (ddPCR) have demonstrated significant advantages and are increasingly becoming core components of the detection framework. Antigen testing plays a critical role in rapid screening, particularly in settings such as schools, workplaces, and communities. Serological assays provide unique value for retrospective outbreak analysis and assessing population immunity. Next-generation sequencing (NGS) has become a powerful tool for identifying novel pathogens and monitoring viral mutations. Furthermore, point-of-care testing (POCT), enhanced by miniaturization, biosensing, and artificial intelligence (AI), has extended diagnostic capacity to the front lines of epidemic control. In summary, the future of epidemic and pandemic response will not depend on a single technology, but rather on a multi-layered and complementary system. By combining laboratory diagnostics, distributed screening, and real-time monitoring, this system will form a global diagnostic network capable of rapid response, ensuring preparedness for the next global health crisis.}, }

However, cell-free virus spread is vulnerable to host-neutralizing antibodies. As population immunity developed, mutations that confer escape from neutralization were selected. Notably, cell syncytia formation wherein an infected cell fuses with a noninfected cell is a more efficient route of transmission that bypasses humoral immunity. Cell syncytia formation has been implicated in the pathogenicity of SARS-CoV-2 infection whilst compromising host transmission due to impaired whole virion release. Therefore, understanding the mechanisms of virus-mediated cell-cell fusion will aid in identifying and targeting more pathogenic strains of SARS-CoV-2. Whilst the general kinetics of cell-cell fusion have been known for decades, the specific mechanisms by which SARS-CoV-2 induces fusion are beginning to be elucidated. This is partially due to emergence of more reliable, high throughput methods of quantifying and comparing fusion efficiency in experimental models. Moreover, the ongoing inflammatory response and emerging health burden of long COVID may point to cell-cell fusion in the pathogenesis. In this review, we synthesize current understanding of SARS-CoV-2-mediated cell-cell fusion and its consequences on immune escape, viral persistence, and the innate immune response.}, }

Antiseptic mouthwashes were proposed as adjunctive measures to temporarily reduce oral viral load. Objectives: This scoping review aims to investigate the role of the oral cavity in viral infections, focusing on saliva and the use of antiseptic mouthwashes to reduce salivary viral load. Methods: Following the PRISMA-ScR guidelines, PubMed, EMBASE, and Web of Science were searched for human studies (2015-2025) investigating oral viral infections, saliva, or mouthwashes. Eligible studies were classified and analyzed for population, intervention, and outcomes. Results: Twenty-three studies met inclusion criteria (sixteen randomized controlled trials and seven systematic reviews). All included studies focused exclusively on SARS-CoV-2, as no clinical evidence on other oral viruses met the eligibility criteria. Saliva was consistently identified as a reliable, non-invasive specimen reflecting disease dynamics and transmission potential. Mouthwashes containing povidone-iodine, cetylpyridinium chloride, chlorhexidine, hydrogen peroxide or β-cyclodextrin-citrox produced measurable but short-lived reductions in salivary viral load. Heterogeneity and lack of standardized outcomes limited comparability. Conclusions: Antiseptic mouthwashes can provide a transient and complementary reduction in salivary viral load, particularly before aerosol-generating procedures; however, they should be regarded only as adjunctive measures and not as substitutes for standard infection-control protocols.}, }

The rapid outgrowth of the trade's governing legislature, fuelled by contemporary consumer culture and the high degree of trader anonymity provided by the internet, has enabled a high-volume, untraceable and profit-driven market to evolve. Increased demand for puppies, exacerbated by social media trends and the COVID-19 pandemic, is sustained by an online medium that both encourages and capitalises upon modern-day 'click-and-collect' purchase behaviour. Moreover, the internet has only intensified the demand for pedigree and designer crossbreeds, many of which are shown to suffer lifelong physiological disorders caused by the positive phenotyping selection necessary to achieve breed standards. These factors have made puppies an attractively lucrative, low-risk commodity. Evidence of multi-level fraud and organised crime involvement has been revealed along the supply chain, resulting in systemic canine health and welfare issues. Whilst large-scale breeding operations reportedly smuggle unvaccinated puppies onto the British market from endemic (rabies, Leishmania) countries, high densities of pet dogs in urban areas is reportedly leaving high faecal-saturation levels, spreading anthelmic- and antibiotic-resistant pathogens.

Social isolation (SI), defined as the objective reduction in social interaction, poses a significant threat to the integrity of this system. In this review, we synthesize evidence from human and animal studies to elucidate the biological, cognitive, and behavioral consequences of SI on the social brain. We describe how SI acts as a chronic stressor, disrupting structural connectivity, and altering neurotransmitter systems critical for social cognition. These disruptions manifest in altered social behavior, mentalization processes, and emotional reactivity, significantly contributing to increased vulnerability to psychiatric and neurodegenerative disorders, including depression, schizophrenia, substance use disorders, and Alzheimer's disease. Converging findings from studies of evolutionarily conserved mechanisms in rodent and primate models demonstrate that SI compromises neurodevelopment, attenuates neuroplasticity, and triggers maladaptive stress responses, highlighting that social deprivation has profound neurobiological and behavioral consequences that greatly overlap with the pathophysiological changes seen in neuropsychiatric disorders. Furthermore, we explore the role of indirect stressors resulting from SI such as touch deprivation and digital-era social disconnection as contemporary amplifiers of SI's neurobiological impact. In light of public health challenges such as the COVID-19 pandemic, we propose that SI should be recognized not only as a psychosocial condition but as a modifiable risk factor with transdiagnostic significance across psychiatry, neurology, and preventive medicine. Addressing SI through targeted interventions and policy measures is essential for promoting mental resilience and well-being.

While several studies have explored its use, the effectiveness of nurse-led telecare consultations in post-acute stroke care remains unclear.<br><br>OBJECTIVE: This study aimed to evaluate the effectiveness of nurse-led telecare consultation for poststroke management among stroke survivors who were discharged from the hospital and lived in the community.<br><br>METHODS: A systematic search was conducted across 6 databases-CINAHL, MEDLINE, PsycINFO, PubMed, Embase, and CENTRAL-for randomized controlled trials published from inception to February 2025. Included studies examined nurse-led telecare consultations compared to usual care among stroke survivors living in the community. Studies involving individuals who were hospitalized or institutionalized were excluded, along with reviews, abstracts without full texts, non-English or non-Chinese articles, and studies not meeting the criteria for randomized controlled trials. Primary and secondary outcomes included blood pressure (BP), psychological burden, quality of life, medication adherence, health care service use, stroke recurrence, survivor functioning, and coping. Continuous outcomes were analyzed using mean differences (MDs) or standardized MDs with 95% CIs under a random-effects model and dichotomous outcomes using odds ratios with 95% CIs via the Mantel-Haenszel method. Heterogeneity was assessed using the chi-square test and I[2] statistics.<br><br>RESULTS: In total, 9 studies involving 2524 participants were included. Ischemic stroke was the most common type (n=1568, 62.13%) of stroke. Meta-analysis showed that nurse-led telecare significantly increased the likelihood of achieving target BP (odds ratio 2.33, 95% CI: 1.83-2.98; P<.001). For continuous outcomes, pooled analyses showed nonsignificant but directionally favorable reductions in systolic BP (MD -4.83, 95% CI -12.51 to 2.85; I[2] =92%), diastolic BP (MD -6.41, 95% CI -13.76 to 0.93; I[2]=97%), and low-density lipoprotein cholesterol (MD 0.01, 95% CI -0.08 to 0.09; I[2]=97%). Heterogeneity was substantial for several key outcomes (I[2]>90% for systolic BP and diastolic BP). Some outcomes, such as medication adherence and stroke recurrence, were reported by only 1 (11.11%) study. Additional benefits were observed in coping ability and reduced hospital readmissions, but findings for psychological well-being and quality of life were mixed.<br><br>CONCLUSIONS: Nurse-led telecare consultations may support better BP management and coping and reduce hospital readmissions among community-dwelling stroke survivors. However, the pooled effects for continuous outcomes were inconclusive, and heterogeneity remained high. Therefore, these findings should be interpreted with caution, and further high-quality trials with standardized outcome measures and longer-term follow-up are warranted to confirm effectiveness.<br><br>TRIAL REGISTRATION: PROSPERO CRD42023492692; https://www.crd.york.ac.uk/PROSPERO/view/CRD42023492692.}, }

Randomized controlled trials indicated that MVM use improved global cognition, episodic memory, and immediate recall in older or cognitively intact adults, reduced psychological symptoms in healthy individuals, and lowered systolic blood pressure in at-risk populations. However, no benefits were found for all-cause mortality, COVID-19 outcomes, visual acuity, or multiple cognitive domains, and a higher risk of age-related macular degeneration progression was reported. Observational studies found associations between MVM use and a reduced risk of colorectal cancer, coronary heart disease, cataracts, and fragility hip fractures, but not breast or prostate cancer, stroke, or overall mortality. During pregnancy, MVM supplementation was linked to reduced risks of small-for-gestational-age births and pediatric cancers, but not to preterm birth, stillbirth, or low birth weight. Overall, the findings revealed a lack of consistency in the definition of MVM supplementation, and substantial variability in MVM effectiveness depending on population, age, and health status. These results highlighted the importance of shifting from generalized supplementation approaches to more targeted, personalized nutritional strategies to support healthspan and longevity.}, }

While non-COVID patients (n = 138) maintained pre-pandemic outcome levels, COVID-positive patients showed reduced functional independence at discharge, with distinct trajectories based on infection timing, even after controlling for status at admission. Patients infected during rehabilitation (n = 36) experienced longer stays and higher readmission rates compared to those infected pre-admission (n = 87). Qualitative analysis identified psychosocial, discharge planning, and resource management issues affecting both COVID-positive and non-COVID patients, emphasizing the impact of social isolation. Integration of findings led to 5 consensus-based recommendations: adaptation of COVID unit environments, family involvement, socialization promotion, safe care trajectory planning and flexible local management.

Circulating nucleic acids (CNAs), high-mobility group box 1 (HMGB1), von Willebrand factor (vWF), and S100b protein are notable markers of SI, indicative of tissue damage and implicated in thrombotic disorders. Innate immunity, involving cells like macrophages and dendritic cells, recognizes DAMPs via pattern recognition receptors (PRRs) like Toll-like receptors and NOD-like receptors, initiating inflammatory signaling cascades central to SI and its cardiovascular consequences. Thrombosis, a common outcome of SI, underscores the intricate interplay between inflammation and hemostasis, with hypoxia exacerbating thrombotic risk through platelet activation and endothelial dysfunction. The established link between inflammation and thrombosis highlights the clinical significance of SI, where molecules like HMGB1, extracellular RNA (eRNA), and eDNA actively participate in thromboembolic disorders. SI's relevance is particularly evident in COVID-19-induced thrombotic disorders, where dysregulated immune responses and endothelial dysfunction contribute to systemic inflammation and heightened thrombotic risk. Understanding SI's mechanisms in these contexts is vital for developing targeted therapies to mitigate vascular complications and enhance patient outcomes in cardiovascular diseases and COVID-19-associated thrombosis.}, }

Booster-vaccinated individuals exhibited higher compliance than partially vaccinated or unvaccinated counterparts. Unvaccinated individuals intending to vaccinate reported higher risk perception than those refusing vaccination.

Previous iterations of this review provided clear and conclusive evidence of superior test performance in those experiencing possible signs and symptoms of Covid-19. However, test performance in asymptomatic individuals and sensitivity by setting and indication for testing remains unclear. This is the fourth iteration of this review, first published in 2020.<br><br>OBJECTIVES: To assess the diagnostic accuracy of rapid, point-of-care antigen tests (Ag-RDTs) for diagnosis of SARS-CoV-2 infection in asymptomatic population groups.<br><br>SEARCH METHODS: We searched the COVID-19 Open Access Project living evidence database from the University of Bern (which includes daily updates from MEDLINE and Embase and preprints from medRxiv and bioRxiv) on 17 February 2022. We included independent evaluations from national reference laboratories, FIND and the Diagnostics Global Health website. We did not apply language restrictions.<br><br>SELECTION CRITERIA: We included test accuracy studies of any design that evaluated commercially produced, rapid antigen tests in asymptomatic people tested because of known or suspected contact with SARS-CoV-2 infection, known SARS-CoV-2 infection or known absence of infection, or those who were being screened for infection. We included evaluations of single applications of a test (one test result reported per person). Reference standards for presence or absence of infection were any laboratory-based molecular test (primarily reverse transcription polymerase chain reaction (RT-PCR)).<br><br>DATA COLLECTION AND ANALYSIS: We used standard screening procedures with three reviewers. Two reviewers independently carried out quality assessment (using the QUADAS-2 tool) and extracted study results. Other study characteristics were extracted by one review author and checked by a second. We present sensitivity and specificity with 95% confidence intervals (CIs) for each test, and pooled data using the bivariate model. We investigated heterogeneity by including indicator variables in the random-effects logistic regression models. We tabulated results by test manufacturer and compliance with manufacturer instructions for use and according to symptom status.<br><br>MAIN RESULTS: We included 146 study cohorts (described in 130 study reports). The main results relate to 164 evaluations of single test applications including 144,250 unique samples (7104 with confirmed SARS-CoV-2) obtained from asymptomatic or mainly asymptomatic populations. Studies were mainly conducted in Europe (85/146, 58%), and evaluated 41 different commercial antigen assays (test kit). Only six studies compared two or more brands of test. Nearly all studies (96%) used RT-PCR alone to define presence or absence of infection. Risk of bias was high because of participant selection (13, 9%); interpretation of the index test (3, 2%); weaknesses in the reference standard for absence of infection (3, 2%); and participant flow and timing (46, 32%). Characteristics of participants (11, 8%) and index test delivery (117, 80%) differed from the way in which and in whom the test was intended to be used. Estimates of sensitivity varied considerably between studies, with consistently high specificities. Average sensitivity was 55.0% (95% CI 50.9%, 59.0%) and average specificity was 99.5% (95% CI 99.5%, 99.6%) across the 147 evaluations of Ag-RDTs reporting both sensitivity and specificity (149,251 samples, 7636 cases). Average sensitivity was higher when epidemiological exposure to SARS-CoV-2 was suspected (58.6%, 95% CI 51.4% to 65.5%; 43 evaluations; 15,516 samples, 1483 cases) compared to where COVID-19 testing was reported to be widely available to anyone on presentation for testing (53.0%, 95% CI 48.4% to 57.5%; 103 evaluations; 129,032 samples, 5660 cases); however CIs overlapped, limiting the inference that can be drawn from these data. Average specificity was similarly high for both groups (99.4% and 99.6%). Sensitivity was generally lower when used in a screening context (summary values from 40.6% to 42.1% for three of four screening settings) compared to testing asymptomatic individuals at Covid-19 test centres (56.7%) or emergency departments (54.7%). We observed a decline in summary sensitivities as measures of sample viral load decreased. Sensitivity varied between brands. When tests were used according to manufacturer instructions, average sensitivities by brand ranged from 36.3% to 78.8% in asymptomatic participants (14 assays with sufficient data for pooling). None of the assays met the WHO acceptable performance standard for sensitivity (of 80%) based on meta-analysis; however, sensitivities from individual studies (where meta-analysis was not possible) exceeded 80% for three assays. The WHO acceptable performance criterion of 97% specificity was met by all but four assays (based on individual studies or meta-analysis) when tests were used according to manufacturer instructions. At 0.5% prevalence using summary data for asymptomatic people, where testing was widely available and where epidemiological exposure to COVID-19 was suspected, resulting PPVs would be 40% and 33%, meaning that 3 in 5 or 2 in 3 positive results will be false positives, and between 1 in 2 and 2 in 5 cases will be missed.<br><br>AUTHORS' CONCLUSIONS: Evidence for antigen testing in asymptomatic cohorts has increased considerably since the publication of the previous update of this review. Average sensitivities remain lower for testing of asymptomatic when compared to symptomatic individuals; however, there is an indication that sensitivities may be higher where epidemiological exposure to SARS-CoV-2 is suspected compared to testing any asymptomatic individual regardless of indication. Sensitivities were particularly low when antigen tests were used in screening settings.

Primary studies were included if they used qualitative methods reporting findings related to barriers or facilitators to the implementation of AT (eg, ambient and wearable sensors, alarms, telehealth or mobile health [mHealth]) for older adults (from the perspective of either carers or older adults) in community settings. All data were screened independently by two reviewers. Study quality was assessed using the Critical Appraisal Skills Program (CASP). Data from each included study were synthesized using thematic synthesis, before barriers were mapped against the domains of the Technology Acceptance Model (TAM).<br><br>RESULTS: Ninety-five studies were included in the review. The number of studies published in the field of barriers to AT use has increased 3-fold post-COVID-19 in comparison to the previous decade. Ten barriers-privacy, cost, insufficient knowledge, fear of misuse, usability, poor functionality, perceived lack of need, stigma, and lack of human interaction-were identified, as well as three facilitators-awareness of health benefits, targeted training, and user-centered design. Persistent barriers relating to all domains of the TAM were identified, with the majority of these relating to the "behavioral intention to use" domain (cost, privacy, stigma, and fear of misuse). The majority of studies had a moderate/high risk of bias.<br><br>CONCLUSIONS: There remain distinct barriers to sustained usage of AT for the care of older adults, particularly concerning adoption as defined by the TAM.

The negative patient and staff experiences and poor clinical outcomes from overcrowding are evident and necessitate solutions to address this ongoing problem. Hospitals providing ED waiting time estimates to patients and staff are becoming popular; however, the more common methods, such as using rolling averages, suffer from an inability to capture the nuanced relationships within an ED. Recent applications of AI and machine learning (ML) in healthcare raises the possibility of applying these techniques to individualized waiting time predictions in the ED; although, literature on the topic is sparse.<br><br>METHODS: A systematized search was conducted on November 10th, 2025, using the electronic databases CINAHL, EMBASE (OVID), Medline (OVID), PsychINFO, Web of Science, and PubMed. Articles were considered for review if written in English, peer-reviewed, published after 2014, and used AI techniques. Descriptive analysis was performed on the final extracted data to facilitate the identification of common themes across studies. Themes were inferred from the proportional usage among studies, of different data preparation, feature selection, and modeling strategies.<br><br>RESULTS: The search identified 8613 citations that, after a rigorous screening process and critical appraisal, were narrowed down to 15 studies for final review. Most included studies were observational, using historical medical record data to compare modeling techniques or demonstrate a proof of concept. Studies commonly used one or more of ED queue-based, staff/resource-based, patient-based, and time-based feature categories. Incorporated AI methods included Random Forest, Linear Regression, and Least Absolute Shrinkage and Selection Operator (LASSO) techniques, among several others. All forms of AI and ML outperformed traditional rolling average estimates used by hospitals.<br><br>CONCLUSIONS: This review identified applications of AI in predicting individualized patient waiting times in the ED that outperform current waiting time estimate strategies. The use of nonlinear techniques, such as the Random Forest method, or incorporating queue-based feature categories, appeared to provide better performance in predictive estimates. Depending on the end user and modality in which the wait time estimate is conveyed, the importance of model selection is highlighted as a consideration to be made if overestimates or underestimates are preferred.}, }

Genetic association studies for IPF have identified several associations and probable effector genes that could not only help understanding IPF pathogenesis but also develop effective treatments. Assessing genetic overlap between IPF and severe COVID-19, an acute respiratory disease that can trigger pulmonary fibrosis, may reveal shared aetiology and mechanisms, thereby supporting the development of common treatments.<br><br>METHODS: We carried out genome-wide association studies (GWAS), post-GWAS, and rare variant analyses using whole genome sequencing data from the 100,000 Genomes Project IPF cohort (n = 586). We performed a meta-analysis combining 100 kGP with published IPF GWASs (total 11,746 cases and 1,416,493 controls). We tested inhibition in vitro for a probable effector gene of an identified association. We also investigated genetic colocalisation between IPF and severe COVID-19 and leveraged their genetic correlation through multi-trait meta-analysis for discovery.<br><br>FINDINGS: IPF meta-analysis identified an additional association at 1q21.2 (rs16837903, OR [95% CI] = 0.88 [0.85, 0.92], P = 9.5 &#xd7; 10[-9]), which was replicated in independent data. MCL1, one of the probable effector genes of the 1q21.2 signal has a known antiapoptotic role, but MCL1 inhibition in vitro did not selectively deplete senescent alveolar epithelial cells. Rare variant burden analysis identified ANGPTL7, a secreted glycoprotein involved in the regulation of angiogenesis, as an IPF candidate gene (OR [95% CI] = 28.8 [8.51, 97.4], P = 6.7 &#xd7; 10[-8]). We discovered additional shared genetic loci between IPF and severe COVID-19 at 1q21.2, 6p24.3, and 16p13.3, with probable effector genes MCL1, DSP, and RHBDF1, implicating regulation of apoptosis, cell adhesion, and epidermal growth factor signalling, respectively. The genetic correlation between IPF and severe COVID-19 was rg [95% CI] = 0.39 [0.25, 0.53]. Using multi-trait meta-analysis, we identified and replicated an additional candidate IPF signal at 2p16.1 with probable effector gene BCL11A, a regulator of haematopoiesis and lymphocyte development.<br><br>INTERPRETATION: These findings prioritise probable effector genes mediating IPF risk and identify potential therapeutic targets that require validation, with genes colocalising with severe COVID-19 suggesting potential for developing common treatments.<br><br>FUNDING: None.}, }

Social and structural factors influence individuals' trust in health care and engagement in health-promoting behaviors. This study investigates racial-ethnic differences in COVID-19 prevention behaviors and beliefs among public housing residents in the South Bronx, NYC. Data come from the Nurse-Community-Family Partnership study, a randomized controlled trial conducted during the COVID-19 pandemic. The analytic sample (n = 200) was limited to adult participants who identified as non-Hispanic Black, Hispanic Black, Hispanic White, or Hispanic Other. Multilevel logistic regression models estimated odds ratios and 95% confidence intervals, adjusted for sex, age, and education. The odds of receiving a COVID-19 vaccine were 3.8 times greater for Hispanic White participants and 2.5 times greater for Hispanic Other participants than for non-Hispanic Black participants. In addition, the odds of practicing social distancing were 2.2 times greater for Hispanic Other participants than for non-Hispanic Black counterparts. COVID-19-related government mistrust was associated with an 88% decrease in the odds of vaccinating, a 58% decrease in the odds of practicing social distancing, and a 77% decrease in the odds of mask-wearing. COVID-19 vaccine mistrust was associated with a 93% decrease in the odds of vaccination. When adjusted for mistrust, differences in vaccination rates by racial-ethnic groups were no longer significant. Addressing mistrust is pivotal for improving public health outcomes. Interventions that enhance trust in health institutions through cultural competence, community engagement, and greater representation in health care can help bridge the gap in prevention behaviors among racially minoritized groups.}, }

Studies explored the experiences of women in various forms of informal work including sex workers, domestic workers, traders/vendors and home-based workers. Four themes were generated: (1) exacerbation of existing vulnerabilities; (2) negotiation of risks and resilience; (3) interconnectedness of health and wellbeing stressors; and (4) variable experiences across social locations. Financial strain from livelihood loss was the primary stressor during the pandemic, and through cascading effect impacted other health and wellbeing domains. Stressors experienced were deeply interrelated and shaped by structural determinants - socioeconomic, political and cultural - as well as pandemic response policies.

Financial constraints, geographical barriers, and awareness gaps influenced healthcare utilization for NCDs. While 60.5% relied on government services for affordability, 39.4% preferred private care for faster access. Out-of-pocket expenses, particularly for hemodialysis and cardiac interventions, posed a major financial burden. Treatment adherence varied by 70.1% among diabetic patients but only 32.4% among hypertensive women. Stockouts of essential medications in public hospitals and high costs of branded drugs in private facilities further restricted access. Emergency care utilisation was high for ischemic heart disease, while CKD patients faced long-term financial strain due to dialysis and frequent hospitalisations.

In the aftermath of the COVID-19 pandemic, cases of major depressive disorder (MDD) or clinical depression have risen by 28% particularly among women and young adults. Characterized by persistent low mood, cognitive impairment, suicidal ideation, sleep disturbances, appetite changes, and fatigue, depression continues to impose a profound public health burden, compounded by the limited efficacy of current treatments and the lack of reliable diagnostic or predictive biomarkers. While the gut microbiota has been extensively implicated in depression's pathophysiology, emerging evidence indicates that the oral microbiome which ranks second only to the gut in microbial diversity also plays a significant role in neuropsychiatric health. Oral microbial dysbiosis may contribute to depression through immune, inflammatory, and neuroactive pathways, positioning the oral microbiome as both a potential non-invasive biomarker and a novel therapeutic target. Incorporating oral microbial profiling into clinical research could not only refine our understanding of depression's underlying mechanisms but also facilitate the development of microbiome-based strategies in precision psychiatry. This growing recognition highlights the importance of expanding research beyond the gut-brain axis to encompass the oral-brain axis as an integral component in the quest for effective diagnostics and interventions.}, }

Adaptive platform trials (APTs) have been promoted as a solution, offering a framework that tests multiple therapies under a single protocol, with arms added or dropped as evidence accumulates. However, their advantages come with trade-offs that warrant scrutiny. In this review, we critically appraise 3 landmark APTs. The I-SPY2 trial accelerated Phase II oncology research by utilizing Bayesian adaptive randomization and surrogate endpoints; however, much of its efficiency stemmed from relying on intermediate outcomes, which may not reliably predict survival. RECOVERY demonstrated the power of scale on a pragmatic UK-wide platform, but its success reflected health system infrastructure, political leadership, and the unique circumstances of the COVID-19 pandemic as much as its design. REMAP-CAP, a perpetual platform trial for pneumonia, rapidly switched to pandemic mode in 2020 and tested COVID-19 therapies using Bayesian models and response-adaptive randomization (RAR); however, the RAR amplified random noise in some domains, exposing patients to interventions later shown to be ineffective. A recent systematic review confirmed wide heterogeneity in APTs and suboptimal reporting. APTs are not inherently better than classical RCTs. Gains in speed may depend on less rigorous endpoints, complex adaptive methods, or streamlined oversight, each of which introduces new risks of error. As APTs spread to new fields such as transfusion medicine, clinicians and researchers must learn to recognize both the potential benefits and the pitfalls of this design.}, }

Of the 15 remaining, seven assessed burnout or emotional exhaustion, seven assessed anxiety, and seven assessed depression (there was overlap). Only two studies were longitudinal and they focussed on burnout; the remaining 13 were cross-sectional in design. Questionnaires were used to assess severity scores. Mean severity scores for all outcomes appear to fluctuate across the pandemic, but are always high. Loss-to-follow up &#x2013; indicated in the longitudinal studies &#x2013; could mean a healthy worker effect (e.g. workers who fall ill and drop out of the study) biases both severity scores per se and their associations with other factors toward null in studies. Differences in- and associations with- outcome scores are reported for sex, age, job experience, cognitive-, personality-, and emotional intelligence-associated factors (e.g. extraversion, presenteeism, openness, resilience, clarity, repair), work-related factors (e.g. student issues, professional support, technology), and COVID-19 associated factors (e.g. family member vulnerability). There are differences in some findings across studies.<br><br>DISCUSSION: The COVID-19 pandemic presented a unique situation in which to study factors that contribute to -or provide protection against- burnout, anxiety, and depression. Female teachers may be a higher-risk group for depression. Potential factors that could be modified to mitigate outcomes, albeit identified as associating factors from mostly cross-sectional studies, include emotional intelligence training at the individual level and professional support at a systems level.

The non-united array of chronic, multisystemic events, such as fatigue, cognitive deficit, respiratory dysfunction, cardiovascular abnormalities, and neuropsychiatric disorders characterize this sequela, which is referred to as LCS. LCS is much more than the starting viral insult, as it causes long-term complications that impact various organ systems. The current review questions the pathophysiological mechanisms of LCS, including scrutinizing the importance of the dysregulation of immunity, the persistence of viral reservoirs, endothelial dysfunction, autonomic imbalance, and mitochondrial injury. We highlight the heterogeneity of the syndrome and the associated diagnostic and treatment difficulties. In addition, we stress the urgency of powerful biomarkers that will be used to diagnose LCS as early as possible and monitor it over time. Present treatment strategies, including pharmacologic therapy (immunomodulators, anticoagulants, antiviral medications, etc.) and non-pharmacologic treatment (rehabilitative programs, etc.) are discussed against the backdrop of recent clinical findings. This review incorporates the recent literature and presents a review of potential treatment options that alleviate symptoms and improve the quality of life of LCS patients. Finally, this integrated synthesis can be used by both clinicians and researchers to gain practical information on the diagnosis, treatment, and future treatment directions of LCS.}, }

While previous reviews have examined the association between long-term care staffing and care outcomes for residents, none have examined specifically how staffing structures affect the care-workers themselves.<br><br>OBJECTIVE: The aim of this review is to investigate how staffing structures impact the quality of work-life, work-related outcomes of care-workers and the context that affects staffing decisions.<br><br>METHODS: A narrative scoping review of primary empirical peer-reviewed literature was conducted to examine how long-term care staffing structures impact quality of work-life and work outcomes of care-workers in OECD countries. PubMed, CINAHL, and Scopus databases were searched for relevant articles published within the past 10&#xa0;years. Searches yielded 4561 unique articles, which were independently screened by pairs of reviewers, of which 76 articles were included. Data were extracted and synthesized to examine the ways in which staffing structures impact the workforce, what structures existed, and how they came to be.<br><br>RESULTS: Contextual factors shaped staffing decisions in long-term care, including both organizational/regulatory practices and external issues. These included market-based ideologies, increased care complexity, regulatory requirements, COVID-19, and organizational fiscal austerity, which affected the quality of work-life and work outcomes for care-workers. These factors contributed to chronic understaffing, restructuring of skill mix, and greater reliance on agency workers. Consequences for care-workers included work intensification, unpaid labour, and strained team dynamics, particularly where registered nurse oversight was limited. While some homes developed adaptive strategies to buffer these effects, inadequate staffing often eroded job quality, undermined teamwork, and contributed to job dissatisfaction, turnover, presenteeism, and adverse physical and psychological health outcomes.<br><br>CONCLUSIONS: This review shows that staffing structures have consequences for quality of work-life and work outcomes. A reliance on lean staffing eventually destabilizes the workforce, perpetuating recruitment and retention issues. This review suggests that to create and maintain a strong long-term care workforce, sufficient staffing with the right skills and competencies need to be a priority in improvement initiatives.<br><br>REGISTRATION: Not registered.}, }

With the outbreak of the COVID-19 pandemic, the usage of TCS has significantly increased, leading to a growing pollution issue that has attracted considerable attention. Therefore, assessing the current TCS pollution status is vital. This review discusses distribution and migration of TCS across various environmental matrices and wastewater treatment systems. Especially, the study summarizes the concentration differences of TCS in human and biological tissues across different countries, finding higher TCS pollution levels in economically developed and densely populated regions. TCS detection methods provide technical support for assessing the distribution of TCS pollution. This paper evaluates the advantages and disadvantages of various pretreatment methods while exploring the development of different detection techniques. Optimized methods are now capable of analyzing TCS in complex matrices, with some methods achieving detection limits in the nanogram range. Notably, TCS has toxic hazards, and can be transformed into more toxic substances in the environment. It induces adverse effects on organismal growth, development, and reproduction, including inhibiting photosynthesis, reducing hatch rates, and increasing cancer incidence. Therefore, developing effective TCS removal technologies is important for environmental protection and human health. This paper systematically analyzes degradation pathways and removal efficiencies of various TCS removal technologies, offering theoretical guidance for TCS pollution management. In summary, this study offers new theoretical insights and practical solutions for tackling TCS pollution, supporting environmental management and public health policy development.}, }

This rapid scoping review examined how three selected healthcare system factors, which we have called 'drivers'-antimicrobial use, infection prevention and control and health system use-were affected by COVID-19 and how they have impacted resistance.<br><br>METHODS: Peer-reviewed searches were performed in MEDLINE, Embase and Cochrane on 19 December 2022 and updated on 25 February 2023 and 1 September 2023. Results of these searches were integrated with an initial search run on 19 October 2022, using the WHO COVID-19 Research Database. References of included studies were also searched to identify any additional relevant studies. Data on the three drivers from included studies were assessed to determine whether they influenced the emergence, spread or number of resistant infections due to antimicrobial-resistant organisms. Studies were then mapped to identify literature gaps and assessed for equity considerations and quality of evidence.<br><br>RESULTS: 63 studies were analysed. Reported COVID-19 changes to antimicrobial use were associated with increased AMR burden in hospital settings. Conversely, the infection prevention and control measures implemented to reduce COVID spread may have decreased resistance in community settings. Differences in health system use during the COVID-19 pandemic may have increased resistance, although we identified knowledge gaps on COVID-19-related changes in health system use. Few studies considered equity in their analyses and no studies directly mentioned equity. All included studies had a moderate to high risk of bias.<br><br>CONCLUSIONS: COVID-19 led to mixed effects on AMR, which depended on the setting and context. There is a need for more rigorous studies that examine how COVID-19 impacted the health system as well as socioeconomic determinants to provide evidence for future pandemics or health crises. Our findings also underscore the importance of integrating antimicrobial stewardship, robust infection prevention and equity-focused surveillance into pandemic preparedness to mitigate AMR risks in future public health emergencies.}, }

The recent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak resulted in significant morbidity and mortality worldwide, seriously impacting human health and the global economy. Given the lack of effective and specific therapeutics against most emerging or reemerging viruses, the development of effective therapeutic measures against such viruses is urgently needed. Most RNA viruses have RNA-dependent RNA polymerase (RdRp), which is indispensable for the replication and transcription of viral genomes. Moreover, the core structural features of viral RdRps are functionally essential and conserved across a wide range of viruses. Thus, viral RdRp serves as a promising target for broad-spectrum antivirals. In this study, we screened nucleoside analogues from a compound library of Hokkaido University, identifying 2-thiouridine (s2U) as a broad-spectrum antiviral ribonucleoside analogue. In particular, s2U exhibited potent antiviral activity against several positive-strand RNA [ssRNA(+)] viruses, including orthoflaviviruses such as DENV and coronaviruses such as SARS-CoV-2. s2U inhibited RNA synthesis catalyzed by viral RdRp, thereby reducing viral RNA replication and improving the survival rate of mice challenged with lethal DENV2 or SARS-CoV-2 in our animal models. In addition to the potent antiviral activities in vitro and in vivo, s2U exhibited no significant toxicity, suggesting its potential as a broad-spectrum antiviral agent against ssRNA(+) viruses, including orthoflaviviruses and coronaviruses.}, }

In this review, we investigated the seasonality of 15 viral infections in Korea. We analyzed viruses for which national surveillance data are available from the Korea Disease Control and Prevention Agency, including influenza virus, respiratory syncytial virus (RSV), rhinovirus, parainfluenza virus, metapneumovirus, human bocavirus, seasonal coronaviruses, enterovirus, adenovirus, norovirus, rotavirus, Japanese encephalitis virus, Hantaan virus, varicella-zoster virus, and mumps virus. In temperate climates, such as that in Korea, winter peaks are commonly observed for influenza, RSV, and norovirus infections, whereas enteroviruses are more prevalent in summer and early autumn. Parainfluenza viruses exhibit type-specific seasonality (circulating in warmer months from spring to autumn). During the coronavirus disease 2019 pandemic (2020-2021), the incidence of most respiratory and gastrointestinal viral infections analyzed in this study declined substantially owing to non-pharmaceutical interventions, such as social distancing and mask-wearing. After the preventive measures were relaxed, many viruses initially exhibited delayed or atypical seasonal peaks. However, by 2024, the seasonality of most, but not all, viral infections had largely returned to their pre-pandemic patterns. We also reviewed factors influencing viral seasonality, including climatic conditions, vector activity, human behavior, immunity, and viral genetic variation. These findings highlight the dynamic nature of viral seasonality and reinforce the importance of timely surveillance and flexible public health responses tailored to each country's epidemiological landscape.}, }

This study analyses obesity mortality trends from 1968 to 2021, focusing on disparities across age, sex, race, and geographic regions. This population-based descriptive study used national mortality data from the CDC WONDER. Obesity deaths among individuals aged ≥25 years, recorded as the underlying cause, were identified using ICD codes from 1968 to 2021. Age-adjusted mortality rates (AAMRs) per 100 000 individuals were calculated. Temporal trends were analysed using Joinpoint regression. From 1968 to 2021, 174 625 obesity deaths were recorded. AAMRs increased from 1.15 (95% CI: 1.09-1.22) in 1968 to 3.39 (95% CI: 3.31-3.46) in 2019; AAMR rates increased from 3.39 (95% CI: 3.31-3.46) in 2019 to 4.54 (95% CI: 4.45-4.62) in 2021. The decline was noted from 1968 to 1985, followed by an increase until 2019; there was a substantial increase from 2019 to 2021 during the COVID-19 pandemic. Males had higher AAMRs than females during the latter part of the study period. Racial disparities persisted, with Black or African American individuals having higher AAMRs than White individuals during the study period.

However, much of the evidence lacks detail to provide thorough accounts of such events. Nevertheless, we aimed to systematically gather the most comprehensive account of all publicly known incidents involving chemical weapons throughout history. We identified 121 instances of chemical weapon use between 10,000 BCE and October 2023 spanning 49 countries and causing at minimum 2,110,360 injuries and 2,930,769 deaths. Across the 121 incidents, at least 165 chemical agents were used. Of the known chemical agents, the top three were sulphur mustard (n = 16, 12.1%), hydrogen cyanide (n = 12, 7.3%) and chlorine gas (n = 11, 6.7%).

It begins by defining sustainable diets as those that are healthful, have low environmental impacts, are affordable, and culturally acceptable. The discussion includes the history of research on sustainable diets, from initial studies focused on environmental impacts to more recent, comprehensive frameworks that integrate affordability, cultural relevance, and nutritional adequacy as key dimensions of diet sustainability. In addition, the paper highlights recent innovations, such as the Planetary Health Diet of EAT-Lancet and the SHARP model, and the conflicts and optimum trade-offs between sustainability and nutrition, particularly within low- and middle-income countries. Case descriptions of Mediterranean Diet with a focus on Traditional Lebanese Diet, and African Indigenous Foods demonstrate culturally confined dietary patterns associated with sustainability objectives. These examples show that sustainable diets are not a single set of prescriptions, but a series of multiple pathways that are shaped by local food environments, ecological belts, and sociocultural heritages. The paper also describes major policy and governance activities necessary to promote sustainable diets. Finally, the paper addresses measurement challenges and advocates for better indicator options to measure sustainable food systems in all their facets and for participatory and context-specific approaches. The discussion concludes that fairer and culturally diverse inclusion strategies, system change, and political determination are imperative in achieving sustainable diets. Diets able to sustain are posited as agents capable of driving the 2030 agenda, enhancing planetary health and social integrity.}, }

Over the past century, whole-cell pertussis (wP) and acellular pertussis (aP) vaccines were developed and widely adopted, leading to a substantial reduction in the number of pertussis cases. Currently, various strategies are employed to protect different segments of the population, including primary immunization, toddler and school-age boosters, adult boosters, and vaccination in pregnancy (ViP). Nonetheless, pertussis remains a global health challenge with periodic outbreaks occurring every 2-5 years. The non-pharmacological measures implemented during the COVID-19 pandemic resulted in a drastic reduction in the circulation of B. pertussis. However, post-pandemic, there has been a resurgence in pertussis cases. This review aims to explore the post-pandemic global pertussis outbreaks and identify underlying trends to gain insights into the potential contributing factors. As of June 2025, pertussis outbreaks with diverse epidemiological patterns have been reported in at least 42 countries, including 30 aP and 12 wP vaccine-using countries. Some common observations among these countries include low infant immunization rates and an absence of vaccination programs for specific populations such as school-aged children, adults, and pregnant individuals. Additionally, in countries with extensive immunization schedules and high vaccination uptake, outbreaks have occurred in regions with low vaccination coverage rates (VCRs). Multiple interrelated factors may have contributed to the post-pandemic pertussis outbreaks, such as the cyclic epidemiology of pertussis, low VCR, waning vaccine-derived immunity, low uptake of boosters, and lack of lifelong protection through regular boosters. To effectively mitigate the incidence of pertussis outbreaks, it is crucial to administer regular booster vaccinations throughout an individual's lifetime, with particular emphasis on at-risk populations and pregnant individuals.

Low-dose, short-course corticosteroids probably reduce short-term mortality in severe pneumonia (15 studies, 2445 participants; risk ratio [RR], 0.73 [95% CI, 0.57 to 0.93]; I [2&#x2009;]= 14%; moderate certainty) and ARDS (5 studies, 1014 participants; RR, 0.77 [CI, 0.61 to 0.99]; I [2&#x2009;]= 23%; moderate certainty). Corticosteroids may reduce secondary shock in severe pneumonia (9 studies, 1690 participants; RR, 0.49 [CI, 0.26 to 0.92]; I [2&#x2009;]= 55%; low certainty).

This narrative review synthesizes applications reported in the 2022-2025 literature across human, microbial, and viral systems, drawing on peer-reviewed studies as our data source. Representative examples include modeling of SARS-CoV-2 spike and nucleocapsid proteins in virology, assisting cryo-EM interpretation of bacterial ribosomal and membrane-protein complexes in microbiology, and refining conformational hypotheses for human GPCRs in biomedicine. Across these cases, AlphaFold predictions have complemented experimental workflows by accelerating hypothesis generation, improving model fitting within ambiguous density regions (poorly resolved areas of cryo-EM maps), and guiding mutagenesis strategies to probe dynamic conformational states. We also summarize recent method extensions: AlphaFold-Multimer improves multi-chain complex assembly prediction, while molecular dynamics (MD) simulations augment AlphaFold's static models by sampling conformational flexibility and testing stability. Despite these advances, important limitations remain-particularly for intrinsically disordered regions, protein-ligand and protein-cofactor interactions, and very large or transient assemblies-and current community benchmarks indicate that approximately one-third of residues may lack atomistic precision, underscoring uncertainty in flexible or modified segments. Framed within a clear chronological window and evidence base, our analysis highlights both the practical impact and the remaining challenges of integrating AlphaFold with experiment, outlining priorities where further methodological innovation and orthogonal validation are needed.}, }

Measures were defined as any quantitative or qualitative evaluation of performance or impact of virtual care on processes, outcomes, or systems. Articles were excluded if they were not a literature review (eg, primary results, commentaries, letters, protocols), dealt exclusively with pediatric populations, were published in a language other than English, or were abstracts only. Measures from retained articles (1233) were thematically grouped against the Proctor Implementation Research Outcomes framework. The study was reported according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guideline extension for scoping reviews.<br><br>RESULTS: There has been substantial growth in the virtual care literature, particularly since the start of the COVID-19 pandemic. The majority of articles (900/1233, 73.0%) evaluated client outcomes, including satisfaction with virtual care, usability or functionality of platforms, or clinical outcomes. Relative to the other domains of the Proctor framework, implementation measures were poorly defined, and many of the measures were proxy rather than direct measures. Despite the potential impacts of virtual care on health equity, most studies examining health equity were purely qualitative. Measures of safety, privacy, and security of virtual care were sparse and poorly defined. Caregivers play an important role in facilitating virtual visits and providing informal technical support; however, few studies examined implementation or satisfaction with virtual care from the perspective of caregivers. Additionally, clinician experience and acceptance of virtual care have implications for availability and adoption; however, relative to patients, few articles examined this perspective.<br><br>CONCLUSIONS: Our study highlights gaps in current evaluations of virtual care. Work is needed to improve the quality and standardization of virtual care evaluation to ensure reproducibility, generalizability, and comparability of findings. Additionally, compliance with existing measure definitions and conventions should extend to virtual care. Finally, additional theoretical work is needed to standardize and conceptually frame future virtual care evaluations. Future studies should include both the caregiver and clinician as unique perspectives in evaluations and should embed systematic evaluations of the impact of social determinants of health on virtual care access, adoption, and perceptions of care.}, }

Consequently, developing effective viral inhibitors is a critical public health priority. Beyond antiviral drugs, a promising therapeutic strategy involves using immunomodulators, which are antiviral agents that enhance the host's immune system against infection. Phytochemicals (PCHs) derived from plants exhibit diverse bioactive properties, including significant antioxidant and immunomodulatory effects. Notably, PCHs have attracted considerable attention due to their broad-spectrum inhibitory actions against numerous viruses, including SARS-CoV-2, dengue virus, hepatitis viruses, and herpes viruses. Recent research has shown how PCHs may target specific signaling pathways implicated in a cytokine storm, a potentially fatal clinical syndrome characterized by an excessive production of pro-inflammatory cytokines and immune cell activation. Numerous studies have investigated the immunomodulatory effects of PCHs on immune function, specifically their ability to regulate key cellular and molecular interactions within the immune system. Additionally, by modulating host immunity, PCHs can enhance the antiviral response. Furthermore, these substances interfere with complex cellular signaling networks, emphasizing their efficacy in preventing viral infections. This review examines the significant and advanced mechanisms PCHs influence immune function during viral illnesses. We subsequently evaluate the potential applications of PCHs as immunomodulatory agents for treating viral infections and discuss their current clinical limitations.}, }

Sustainability efforts should focus on high-impact areas like energy use, equipment manufacturing, and waste, rather than eliminating valuable pharmacological options. Patient safety and evidence-based practice must remain central as we strive toward a more responsible, nuanced environmental approach in anaesthesia.}, }

In response to the COVID-19 pandemic, the Korea Disease Control and Prevention Agency promptly implemented testing, treatment, and social distancing measures. Only a thorough analysis can evaluate the efficacy of the agency’s COVID-19 response policies. It would be challenging to characterize the lessons and preventative actions learned from the findings as accurate insights. This paper analyzes the COVID-19 pandemic response strategy and governance from January 2020 to December 2021 by placing actions taken within the conceptual framework of infectious disease management policy. This strategy establishes a valuable policy evaluation framework that can integrate limitations of policy decisions in response to pandemic infectious diseases with imbalancing ripple effects. Infectious disease control countermeasures provoke an unexpected secondary outcome, like reduced economic growth or social isolation. It is very difficult to balance these negative consequences with the effectiveness of preventing infectious diseases. In other words, infectious disease prevention strategies can be specific obligations in specific contexts that are derived from ex post accountability. Therefore, infectious disease response policy assessment requires a step-by-step framework to evaluate potential negative impacts, and it is important to set parameters in advance to resolve competing interests arising in particular contexts.}, }

Wastewater surveillance systems can detect emerging infectious diseases or new viral variants in a community earlier than hospital-based clinical surveillance systems, thereby preventing the spread of infections. In particular, it provides a foundation for rapid response to variants with higher transmissibility and virulence. This study aims to examine how wastewater-based pathogen surveillance can be applied to monitor pathogen mutations through case studies from various countries worldwide. Moreover, wastewater surveillance is more cost-effective than mass testing in areas with low clinical testing rates and large populations. Genomic analysis of wastewater can detect several pathogens that may not be captured by clinical surveillance, thereby providing critical information for predicting the emergence of potential variants. In conclusion, wastewater-based pathogen surveillance is a valuable tool in public health management to respond to infectious diseases. It enables the monitoring of infectious disease spread and pathogen mutation trends. In addition, it can function as an early warning system through the analysis of wastewater from communities.}, }

According to the World Health Organization (WHO), approximately 320,000 measles cases were reported worldwide in 2023, 1.8 times higher than approximately 170,000 cases in 2022. Even in countries verified as measles-eradication countries, community epidemics have been observed mainly among unvaccinated and incompletely vaccinated people. The WHO indicated that low vaccination rates and increased international travel are the main causes of the rapid increase in measles outbreaks. During the COVID-19 pandemic, vaccination services were suspended or delayed in many countries, significantly decreasing vaccination rates. Simultaneously, as travel restrictions eased, population movement increased worldwide, creating an environment that made it easy for the measles virus to spread to various regions. The WHO has set the goal of eradicating measles by 2030, and important strategies include maintaining and strengthening vaccination rates, strengthening quarantine, patient surveillance, public health education, and information sharing through international cooperation. As of 2022, the Republic of Korea has maintained a relatively high vaccination rate by meeting the standards for maintaining herd immunity of over 95% recommended by the WHO, with a secondary vaccination rate of 95%. However, there is a risk of transmission through certain age groups and overseas inflows where vaccination rates are relatively low. Therefore, in areas with an active measles outbreak, it is essential to be vaccinated before traveling to areas where outbreaks are increasing, and careful monitoring is necessary to prevent domestic inflow.}, }

The numbers of AEs per ICSR and AE types as well as the probability of having a serious AE per ICSR were lower in the ROK than in the UK. These findings could imply that the ROK might have adopted different standards and processes from those in the UK.

Injectable vaccines often fail to induce effective mucosal immunity, and their efficacy is further compromised by maternally derived antibodies. Oral and intranasal mucosal vaccines offer promising alternatives, enabling localized and durable protection. This review summarizes recent advances in mucosal vaccines against SeCoVs, focusing on antigen delivery platforms and mucosal immune activation. Novel antigen delivery platforms, including nanoparticles (NPs), hydrogels, engineered probiotics, recombinant viral vectors, and eukaryotic expression systems, have improved antigen stability and facilitated transport across the epithelium to mucosal inductive sites. Moreover, targeting strategies that focus on microfold cells (M cells) and dendritic cells (DCs) enhance antigen uptake and presentation. These delivery systems promote mucosal immune activation by inducing secretory IgA (sIgA), maintaining Th1/Th2 balance, and promoting the generation of T and B cells. In addition, the incorporation of adjuvants further strengthens these responses, resulting in more robust and durable protection. By synergistically integrating advanced mucosal vaccine delivery systems with rational adjuvant strategies, this review provides theoretical and practical perspectives for the development of safe, effective, and broadly protective mucosal vaccines targeting SeCoVs infections.}, }

Additionally, vaccine-induced immune thrombotic thrombocytopenia (VITT), linked to adenoviral vector vaccines, presents unique surgical challenges due to a heightened risk of thrombosis and bleeding. This review focuses on the surgical management of COVID-19-associated aortic thrombosis and VITT-related large-vessel occlusions.<br><br>RESULTS: Surgical intervention in COVID-19-associated aortic thrombosis depends on thrombus burden, patient stability, and associated comorbidities. Open thrombectomy, aortic bypass, and hybrid endovascular techniques have been employed, with perioperative anticoagulation being critical to prevent recurrence. High thrombus burden cases often require open repair, while endovascular approaches are preferred in high-risk patients. Mortality rates remain elevated (up to 30%), with post-surgical complications including recurrent thrombosis and limb loss. In VITT cases, surgical revascularization is complicated by thrombocytopenia and a prothrombotic state, necessitating non-heparin anticoagulation and close hematologic monitoring. Delayed diagnosis and inappropriate anticoagulation significantly worsen outcomes.<br><br>CONCLUSION: The surgical management of aortic thrombosis in COVID-19 and VITT patients requires a multidisciplinary approach, incorporating vascular surgery, hematology, and intensive care. Early intervention with individualized surgical and anticoagulation strategies is crucial in optimizing outcomes. Further research is needed to refine surgical decision-making, improve postoperative anticoagulation protocols, and enhance patient survival in these complex thrombotic conditions.}, }

Plain-Language Summary: Staying socially connected is important for older adults' health, well-being, and overall quality of life. This review explored how older adults use digital technologies, such as video calls, email, text messaging, and social media, to stay in touch and participate socially. Interest in these technologies has grown in recent years, especially during the COVID-19 pandemic. Most research focused on communication with family and friends; fewer studies examined forming new relationships online or the quality of online interactions. Digital tools can reduce loneliness and support participation, particularly when in-person contact is limited. However, more research is needed to understand usage patterns and the adoption of these tools in daily life, especially among underrepresented groups. This knowledge can help occupational therapy practitioners better support older adults in using technology to promote meaningful social connections.}, }

Diabetes mellitus is a major comorbidity associated with higher infection risk, severe disease, and mortality in COVID-19 patients. This review examines the bidirectional relationship between COVID-19 and diabetes, focussing on immunometabolic mechanisms, post-COVID metabolic effects, and therapeutic implications. A comprehensive literature search was conducted in PubMed, Scopus, and Web of Science for articles published until May 2025 using the terms "COVID-19," "SARS-CoV-2," "diabetes," and "immunometabolism." Peer-reviewed studies addressing clinical, molecular, or therapeutic interactions between the two diseases were included. Evidence shows that SARS-CoV-2 infection aggravates metabolic dysfunction through immune dysregulation, cytokine-mediated inflammation, and β-cell injury. Hyperglycemia promotes viral replication and inflammatory damage, creating a vicious cycle that worsens outcomes. Reports also indicate an increased risk of new-onset and post-COVID diabetes. Certain antidiabetic agents, such as metformin and GLP-1 receptor agonists, may improve prognosis via anti-inflammatory and metabolic effects. Diabetes significantly amplifies the severity of COVID-19 through intertwined metabolic and immune mechanisms. Understanding these interactions provides new insights into disease management and supports the development of targeted immunometabolic therapies for improving outcomes in diabetic patients affected by COVID-19.}, }

Vaccination has played a crucial role in reducing severe disease and mortality, but the impact of the different vaccine combinations on the development and resolution of Long COVID remains a topic of debate. This review synthesizes current evidence on how different vaccine platforms, dosing strategies and booster doses influence the immunological response, protection, incidence, severity, and persistence of Long COVID symptoms. We discuss key immunological mechanisms by which vaccination may modulate and protect post-COVID syndrome outcomes, including its effects on viral clearance, immune response reprogramming, inflammation, and autoimmunity, seeking to combat misinformation and concepts spread by fake news. The review also highlights controversies and research gaps, such as variability in vaccine response among different populations and the role in the selection of more transmissible and virulent SARS-CoV-2 variants, as well as the potential differences between vaccine-induced and infection-induced immunity, and the role of pre-existing immune conditions in this scenario.}, }

Angiotensin converting enzyme-2 (ACE2) and its interaction with the SARS-CoV-2 Spike glycoprotein, which mediates fusion of the virion envelope with the target cell membrane, have emerged as a major pharmacological target, as disruption of the Spike-ACE2 interaction prevents cells from becoming infected and hence from producing viral progeny. Moreover, the dysregulation of ACE2 that occurs in the context of SARS-CoV-2 infection may have broader implications for COVID-19 pathogenesis.

Preclinical research has propelled the launch of clinical trials with results from initial studies recently published. A systematic review is needed to evaluate trial designs, outcomes, product characterization and safety profiles to identify barriers and inform future research directions.<br><br>METHODS: A systematic search of the literature was conducted (1946 to September 19, 2024) to identify clinical studies using cell-derived EVs. We extracted aspects of study design, diseases being treated, characteristics of trial subjects, isolation methods and characterization of EVs, details of product administration, main conclusions, and aspects of potential study bias.<br><br>RESULTS: Twenty-five published clinical trials were included for analysis. COVID-19 and associated acute respiratory distress syndrome (ARDS) were studied most frequently (n = 8, 32 %). Wound healing was the second largest disease category (n = 5, 20 %). Seven studies (28 %) were controlled trials. Mesenchymal stromal cells (MSCs) were the most common source of EVs (20 studies, 80 %), with 494 patients receiving MSC-EVs for various indications. Most trials (68 %, n = 17) used ultracentrifugation as the primary method for EV isolation. An individual patient data meta-analysis of controlled COVID-19/ARDS trials investigating MSC-EVs (n = 3; 5 intervention groups) revealed an odds ratio (OR) for mortality of 0.46 (95 % CI 0.26 - 0.81; p = 0.0073). The benefits of EVs to improve wound healing are less clear with no controlled studies of MSC-EVs and no clear benefit reported in 2 controlled studies of other cell-based EVs. Although administration of EVs was generally well tolerated, safety conclusions remain preliminary given that only one serious adverse event was explicitly reported, and adverse event reporting was often incomplete.<br><br>CONCLUSIONS: Clinical trials of cell-derived EVs demonstrate marked heterogeneity but potential promise using MSC-EVs to treat COVID-19/ARDS, although efficacy in wound healing is less clear. More controlled studies are needed to optimize and confirm these initial results and to establish a more definitive understanding of the safety profile of EV therapy.}, }

Latine communities experience disproportionately poor COVID-19 and other communicable disease outcomes. The objective of this study is to test psychometric properties of widely used vaccine hesitancy and vaccine acceptance measures among diverse U.S. Latine populations.<br><br>METHODS: We conducted a psychometric meta-analysis of 13,406 Latine survey participants between 2021 and 2023 from 10&#xa0;U.S. Rapid Diagnostics for Underserved Populations Initiative sites. Separate vaccine hesitancy and vaccine acceptance checklists were evaluated using two-parameter logistic item response theory modeling to assess item difficulty, discrimination, and measurement invariance across 6 pandemic waves. External validity was tested with vaccination status and vaccine course completion.<br><br>RESULTS: Vaccine acceptance items performed well in terms of measuring persons low to high in the trait and performed well at differentiating respondents. Generally, the vaccine hesitancy items displayed greater range and variance across the trait of hesitancy (item difficulties) than vaccine acceptance items. Equal slope discrimination could be assumed for the hesitancy items across pandemic waves, but scalar invariance was rejected, indicating that level of endorsement (item difficulties) increased over waves. Both metric invariance and scalar invariance were rejected for vaccine acceptance items, indicating both discrimination and difficulty increased across waves. External validity was supported for vaccine acceptance but not hesitancy. The point biserial correlation for vaccine acceptance was significantly associated with vaccination status (r&#xa0;=&#xa0;0.53, p&#xa0;<&#xa0;.001) and course completion (r&#xa0;=&#xa0;0.09, p&#xa0;<&#xa0;.001).<br><br>CONCLUSIONS: Item characteristics suggest both vaccine acceptance items and hesitancy items exhibited acceptable measurement properties, but vaccine acceptance met thresholds for consistency and external validity. This is the first psychometric testing of these vaccination attitudes measures, adding to validated measures for future use in Latine populations. Moreover, findings corroborate growing evidence of the dissociation between acceptance and hesitancy as constructs related to vaccination attitudes.}, }

Beyond acute infection, growing evidence suggests that persistent exposure to SARS-CoV-2 spike protein, whether through infection or vaccination, may sustain inflammatory pathways that contribute to tumour progression and immune modulation. This review explores the overlap between post-COVID inflammation, particularly in Long-COVID syndromes and the tumour microenvironment (TME), focusing on key mediators such as IL-6, TNF-α, IL-1β, and NF-κB. We revisit the concept of the cytokine storm in the context of persistent inflammation, spike protein immunogenicity and immune exhaustion, proposing a model in which chronic inflammatory signalling may disrupt tumour immune surveillance, reawaken dormant cancer cells and compromise the efficacy of immunotherapies. Comparative analysis with other cancer types highlights shared pathways of oncogenic inflammation. Lastly, we outline emerging therapeutic strategies to mitigate these effects, including cytokine-targeted interventions and immunomodulatory screening in post-COVID cancer patients. These post-pandemic insights call for urgent translational research to ensure effective and safe cancer immunotherapy in the evolving inflammatory landscape.}, }

By comparing the analytical performance of test systems and highlighting their limitations, EQA super challenges and the examination results collected by them are valuable contributions for post-market surveillance of diagnostic tests, aid harmonisation in laboratory medicine, and help to identify areas for improvement for manufacturers, policy makers, and regulators.

Recent advances in nucleic acid-based platforms, particularly mRNA and DNA vaccines, have accelerated clinical translation, especially following the success of mRNA vaccines against SARS-CoV-2. These innovations have enabled improved antigen delivery, immunogenicity, and flexibility through structural modifications such as self-amplifying or chemically modified mRNAs. In parallel, peptide-based vaccines have evolved through the incorporation of long synthetic peptides and the identification of tumor-specific neoantigens. Other strategies include dendritic cell-based vaccines and whole tumor cell approaches. Neoantigen vaccines have demonstrated a favorable safety profile and the ability to elicit robust CD4[+] and CD8[+] T cell responses across various cancer types and disease stages. Optimal efficacy, however, depends on careful antigen selection, favoring clonal, driver mutations, and timely administration, ideally in early-stage or minimal residual disease settings to circumvent immune evasion and systemic immunosuppression. The tumor microenvironment (TME) critically shapes vaccine responsiveness, influenced by both tumor-intrinsic factors (e.g., antigen presentation defects, HLA loss) and extrinsic immunosuppressive cells. High tumor mutational burden and inflamed TMEs correlate with stronger responses, but encouraging outcomes have also been observed in "cold" tumors. Combining vaccines with ICIs, chemotherapy, or cytokine therapies can enhance efficacy by overcoming immune resistance. Optimizing clinical trial design and ensuring cost-effectiveness will be essential for translating personalized cancer vaccines into routine clinical practice.}, }

However, increased longevity does not always translate into enhanced health. While genetic and environmental factors influence lifespan, evidence indicates that targeted interventions can substantially enhance the likelihood of reaching 100 years. This study aimed to characterize disease and risk factor patterns among the oldest-old to identify actionable targets for promoting health and functional capacity in this rapidly growing population.<br><br>METHODS: This study identified 18 countries with the largest populations aged 95 years and older using data from the Global Burden of Disease (GBD) 2023 study and the United Nations World Population Prospects 2024. Disability-adjusted life years (DALYs), years of life lost (YLLs), and years lived with disability (YLDs) from 1990 to 2023 were quantified, ranked, and visualized across three major cause categories (non-communicable, communicable and nutritional diseases, and injuries) and risk factors (behavioral, environmental/occupational, and metabolic) by using the GBD 2023 estimates. Temporal trends were assessed using estimated annual percentage change derived from log-linear regression models, calculated separately for periods before and after the COVID-19 pandemic peak. K-means clustering was employed to identify cross-country burden patterns, with the optimal number of clusters determined via the silhouette method. Temporal trends in health-adjusted life expectancy (HALE) were examined, and frontier analysis was applied to estimate the potential for further HALE improvement across countries.<br><br>RESULTS: From 1990-2023, the absolute disease burden among individuals aged 95&#x202f;+&#x202f;years increased more than fivefold, primarily driven by non-communicable diseases, accounting for &#x223c;86&#x202f;% of the total DALYs. Ischemic heart disease remained the leading cause, particularly for YLLs, followed by Alzheimer's disease and other dementias, which predominated in YLDs, followed by stroke and chronic kidney disease. During the COVID-19 pandemic peak (2019-2021), mental health disorders, including depression and anxiety, demonstrated a marked increase. Cluster analysis in 2023 revealed two distinct national patterns: one dominated by acute cardiovascular conditions and the other by chronic multi-system diseases. Absolute burdens of metabolic, behavioral, and environmental/occupational risk factors increased over time, although their relative contributions declined; high systolic blood pressure (YLLs), high fasting plasma glucose (YLDs), and kidney dysfunction remained the leading risk factors. The average HALE increased from 1.86 years in 1990-2.16 years in 2019, declined during the pandemic, and partially recovered by 2023. Frontier analysis indicated nearly a twofold potential for further HALE improvement under current socioeconomic conditions.<br><br>CONCLUSION: The 95&#x202f;+&#x202f;-year-old population exhibits distinctive patterns of disease burden that have shifted substantially over the past three decades. Despite cross-national differences, cardiometabolic diseases and risk factors, along with multisystem comorbidities from the brain and kidneys, remain the primary drivers. Integrated strategies addressing biological, social, and environmental factors may enhance intrinsic capacity and promote healthy aging in the oldest old.}, }

However, the mechanism remains unclear. This report describes three cases of COVID-19-associated LVV with elevated anti-angiotensin-converting enzyme 2 (ACE2) antibodies.<br><br>CASE PRESENTATIONS: The first case was a 59-year-old man who developed a persistent headache and fever 2&#xa0;weeks after SARS-CoV-2 infection. FDG-PET/CT revealed diffuse vascular inflammation extending from the carotid arteries to the abdominal aorta. The second case was a 71-year-old man who presented with prolonged fever after SARS-CoV-2 infection. Imaging demonstrated vascular wall enhancement and FDG uptake from the thoracic aorta to the iliac aorta. The third case was a 67-year-old man who had persistent fever 10&#xa0;days after COVID-19, with FDG-PET/CT showing uptake from the ascending aorta to the aortic arch. In all cases, workups for immune and infectious diseases were negative. Symptoms and inflammatory markers resolved spontaneously or with nonsteroidal anti-inflammatory drugs. Serum anti-ACE2 IgG was positive during the active phase in all three patients and became negative during remission.<br><br>DISCUSSION: We have encountered three cases of COVID-19-associated LVV with elevated anti-ACE2 antibodies that normalized after clinical remission. There have been multiple reports of LVV following SARS-CoV-2 infection, with onset typically within weeks of infection, and of elevated anti-ACE2 antibody levels in patients with COVID-19-related neurological complications. Further studies are warranted to determine if anti-ACE2 antibodies are associated with the pathogenesis of post-COVID-19 vasculitis.}, }

Of the 116 articles published between January 2024 and June 2025 that mentioned "trust" and "mistrust", only 17 directly engaged with trust in science. Analysis revealed an emphasis on the epistemic aspects of science, with limited attention to affective or political dimensions, and a disproportionate focus on global issues such as COVID-19 and climate change rather than local issues. There was a marked lack of an explicit definition or conceptualisation of 'trust' in the papers. We argue that science education research would benefit from interdisciplinary perspectives on trust, including frameworks on the emotional, relational, and ideological characterisations of trust. Such multiplicity of perspectives is relevant to science education given educational contexts inherently embody not only epistemic but also social, political and affective dimensions. Suggestions are made for future directions in science education research for a critical yet balanced account so that trust in science can be appropriated.}, }

PMH proposes that long-term coevolution reduces parasite peptide vocabularies and drives convergence toward host repertoires - a pattern that can help to infer a parasite's original host.

These individuals have increased vulnerability to vaccine-preventable infectious diseases, and their immune response to vaccination is often weaker than that of immunocompetent individuals. Therefore, whenever possible, it is important to assess vaccine response (serological or other). Emphasis is placed on adapting vaccination to the net state of immunosuppression, following a careful evaluation of risks, indications, contraindications, and the optimal timing for administration. Whenever feasible, vaccination should be carried out before the initiation of pharmacological immunosuppression, prior to splenectomy, or before receiving a solid organ transplant. Immunocompromised individuals are categorised into groups such as those with immune-mediated inflammatory diseases, individuals who have undergone splenectomy, recipients of solid organ or haematopoietic transplants, people living with HIV, and those with congenital immunodeficiencies (inborn errors). The article describes vaccination recommendations for different clinical scenarios and types of immunosuppression. Vaccines against respiratory viral diseases, including influenza, COVID-19, and respiratory syncytial virus, as well as hepatitis A and B, varicella-zoster, and vaccines protecting against encapsulated bacteria such as pneumococci, meningococci, and Haemophilus influenzae, are discussed. Some vaccination recommendations in the context of travel and post-exposure prophylaxis in high-risk situations are included. The article also addresses the importance of vaccinating household contacts and healthcare professionals for additional protection. Finally, it highlights that ongoing advancements in vaccines and vaccination guidelines require continuous updates.}, }

The Healthcare Safety Investigation Branch has issued a safety recommendation aimed at improving fetal growth monitoring strategies and reducing risk for babies.<br><br>OBJECTIVES: The objective was to summarise available evidence to inform the Healthcare Safety Investigation Branch recommendation. The review comprised four research questions on: effects of fetal growth monitoring on neonatal/parental outcomes; effects of implementing fetal growth monitoring guidelines on neonatal/parental outcomes; accuracy of fetal growth monitoring strategies for predicting smallness for gestational age neonates/fetal growth restriction and factors affecting the accuracy of fetal growth monitoring strategies.<br><br>METHODS: Nineteen databases were searched from 2000 to March 2023 and were updated September 2023. Pregnant people with and without risk factors were included. Each review question had further eligibility criteria. For accuracy results, summary estimates of the sensitivity and specificity with 95% confidence intervals for the prediction of smallness for gestational age at delivery were calculated. Random-effects models were used for the meta-analysis of clinical outcomes. Further outcomes, including the results of risk of bias assessments, were summarised narratively.<br><br>RESULTS: Fifty-eight studies (78 publications) were included in the review. Q1 - Antenatal identification of smallness for gestational age pregnancies was associated with increased rates of intervention (two retrospective cohort studies, n&#x2005;=&#x2005;100, 198 and 2928), but the available evidence did not support an effect on stillbirths or neonatal outcomes. Q2 - Meta-analysis (three observational studies and one randomised controlled trial, n&#x2005;=&#x2005;318,523) indicated that implementation of the Growth Assessment Protocol was associated with a reduction in the risk of stillbirth and risk ratio of 0.79 (95% confidence interval 0.74 to 0.84). Meta-analyses (one observational study and one randomised controlled trial, n&#x2005;=&#x2005;11,978) indicated that Growth Assessment Protocol implementation was associated with a reduction in the risk of 5-minute Apgar score <&#x2005;7, risk ratio of 0.78 (95% confidence interval 0.64 to 0.95); however, the effect estimate for neonatal intensive care unit admission was highly uncertain, 0.59 (95% confidence interval 0.02 to 20.03). Q3 (53 studies) and Q4 (15 studies) - regarding accuracy, the highest sensitivity for both general and high-risk populations was achieved using a combination of estimated fetal weight and abdominal circumference tests, where the threshold was defined as either parameter <&#x2005;10th percentile. No clear trends were observed for the type of reference charts, either for the use of general versus local reference charts (either the estimated fetal weight or birthweight) or for the use of non-sex-specific versus sex-specific birthweight reference charts (nine studies).<br><br>LIMITATIONS AND CONCLUSIONS: There is limited evidence linking fetal growth monitoring tests results to the changes in fetal/neonatal outcomes. There is some evidence supporting the reduction of adverse outcomes by Growth Assessment Protocol implementation. Testing during the third trimester is likely to result in more accurate prediction of smallness for gestational age at birth than earlier testing. Use of a locally derived reference chart for estimated fetal weight may result in optimised sensitivity for a given birthweight reference chart (definition of smallness for gestational age).<br><br>FUTURE WORK: Large diagnostic cohort studies and comparative studies are needed to further examine whether and how fetal growth monitoring testing and implementation of guidance can affect clinical outcomes.<br><br>STUDY REGISTRATION: This study is registered as PROSPERO CRD42023408030.<br><br>FUNDING: This award was funded by the National Institute for Health and Care Research (NIHR) Evidence Synthesis programme (NIHR award ref: NIHR135862) and is published in full in Health Technology Assessment; Vol. 29, No. 62.

This review lays bare the lack of robust experimental data to establish the actual existence of P-SILI.<br><br>RECENT FINDINGS: At the height of the COVID-19 pandemic, world-renowned investigators argued that P-SILI was responsible for much of the lung injury in COVID-19 and recommended radical alterations in ventilator management: avoidance of noninvasive ventilation, preemptive intubation, widespread use of neuromuscular blockers to decrease patient-generated tidal volume, and postponement of ventilator weaning. When debated to provide proof for the existence of P-SILI, proponents imparted sparse unconvincing rejoinders.<br><br>SUMMARY: In a scientific debate, the party making a new claim carries the burden of proof, not the side defending the preexisting state of knowledge (analogous to a defendant's presumption of innocence until evidence is produced to the contrary). Claims for the existence of P-SILI are based on the shakiest of circumstantial evidence. Six decades of research on how to prudently select settings and remove/wean the ventilator at the earliest time were abrogated during a pandemic on the warrant of an unproven hypothetical entity.}, }

The quality of the included studies was assessed using the COREQ checklist. A total of 43 qualitative studies were included in the final review.<br><br>RESULTS: Based on COREQ evaluation, most studies demonstrated good methodological quality, with a mean score of 25.81 out of 32 (range: 17-29); no study fully satisfied all COREQ criteria. Thematic synthesis revealed two main categories: (i) Emotional Challenges, which encompassed psychological, physical, technological, and social dimensions; (ii) Coping Strategies, which were classified into cognitive (mindset-based), behavioral (function-based), and technology-assisted strategies. These findings highlight the emotional complexity and adaptability of older adults during isolation.<br><br>CONCLUSIONS: Contrary to initial assumptions of vulnerability, many older adults approached the pandemic with rational understanding and adaptive responses. By drawing on past life experiences, they actively organized coping mechanisms to navigate the crisis. These insights emphasize the need for health policymakers to invest in resilience-building initiatives, such as digital literacy training and community-based emotional and physical support programs.

Virtual examinations for the elbow, shoulder, hip, and knee have been successfully modified for remote assessment. The modifications of some tests now allow patients to perform self-tests under physician guidance using household tools. Randomized controlled trials (RCTs) demonstrate that telehealth consultations are not inferior to in-person evaluations in clinical decision-making. Limitations include the inability to replicate certain hands-on maneuvers, disparities in digital access among minority and low-income populations, and variable patient adherence. To optimize remote care, standardized telehealth protocols, improved image transmission, and targeted patient preparation are required.

Multiple challenges remain, including inequitable access to care, limited organ donation, and structural inefficiencies in allocation systems. To review the current status of LT in Mexico, describe historical trends, highlight significant barriers to progress, and discuss potential opportunities for program expansion. We conducted a narrative review incorporating data from the National Transplant Center (Centro Nacional de Trasplantes in Spanish), relevant peer-reviewed literature, and global benchmarks. The analysis focused on trends in liver transplant volume, donor types, etiology shifts, institutional disparities, and the impact of the coronavirus disease 2019 (COVID-19) pandemic. LT activity in Mexico increased from 25 transplants in 1999 to 297 in 2023. However, over 68% of transplants are concentrated in Mexico City, and only eight centers perform more than ten LTs per year. Deceased donors account for most grafts, while living donor transplants remain rare and mostly limited to private institutions. The national waiting list functions primarily as a registry rather than a priority-based allocation system. The COVID-19 pandemic further disrupted transplant programs, particularly in the public sector. Innovative approaches such as donation after circulatory death, hepatitis C virus-positive donor utilization, and advanced perfusion technologies are currently unavailable or underutilized in Mexico. Mexico's LT system faces geographic, regulatory, and resource-related limitations.

We searched five electronic databases for publications on health visiting during the COVID-19 pandemic from October 2022 to April 2023. This was followed by citation searching and review of organisational websites. Programme theory was iteratively refined through discussions with the team, professional stakeholders and people with lived experience and was translated into key findings and recommendations.<br><br>RESULTS: One hundred and eighteen documents informed this review; most focused on health visiting in England (56%) or the United Kingdom (34%), with relatively few from Wales (6%), Scotland (3%) and Northern Ireland (1%). Documents highlighted the widespread, uneven and lasting impact of the COVID-19 pandemic on babies and families. Findings revealed significant concerns expressed by both families and practitioners and corresponding actions taken by health visiting services. These concerns and responses emphasised the flexibility and resourcefulness of health visitors, the vital role of trusting relationships between health visitors and families and the importance of holistic assessments for early intervention. Changes in service delivery were varied and were not always evaluated or sustainable. While the data illuminated some of the hidden complexities of health visiting practice, limited evidence was found on decision-making at organisational and managerial levels during the pandemic response.<br><br>EVIDENCE LIMITATIONS: Included papers were predominantly from an advocacy or practitioner perspective, and few focused on health visiting in Scotland, Wales and Northern Ireland. Our focus on the universal health visiting pathways meant that documents pertaining to additional support received by the most vulnerable families might have been excluded. Experiences of Black, Asian and minority ethnic families and staff were illustrated in several papers.<br><br>CONCLUSIONS: The COVID-19 pandemic highlighted the essential role of health visitors in safeguarding child and family well-being in the United Kingdom. While digital adaptations provide necessary continuity, face-to-face interactions remain essential for effective health visiting. The crisis exposed pre-existing workforce pressures and inconsistencies in service provision, emphasising the need for adequate support and funding. Policy-makers must recognise the complexity of health visiting and ensure sustained investment in universal home visiting services. Future resilience requires a realistic understanding of health visitors' work, integration into broader child health policies and enhanced interagency collaboration to address inequalities and improve long-term public health outcomes.<br><br>FUTURE WORK: Our implications for policy-makers will be translated into reflexive questions to prompt critical thinking about health visiting services in local areas.

This SARS-CoV 2 induced fibrosis initiates cascade of proinflammatory responses such as cytokine release. EMT (Epithelial-mesenchymal transition) is a central event in post COVID 19 pulmonary fibrosis which is characterized by the accumulation of stimulated fibroblast and myoblast, finally epithelial morphology changed to mesenchymal traits. This transformation is marked by the loss of intercellular adhesion and polarity. A study of SARS-CoV 2 pathogenesis and EMT can provide insights to pulmonary fibrosis. Hence identification of biomarkers of EMT activation helps early diagnosis and determination of therapeutic approaches against pathogenesis. This review focusing on the mechanism of post-covid 19 pulmonary fibrosis through EMT with a special importance to TGF-β/Smad, NF-κB pathways and oxidative stress. Previous studies marked the EMT induced fibronectin, collagen deposition that can potentially disrupt lung structure and its function. SARS CoV 2 infection can trigger Hyper activation of profibrotic pathways like TGF-β/Smad, NF-κB pathways that maintain EMT via downregulation of E-Cadherin and upregulation of vimentin, fibronectin and α-SMA. SARS-CoV spike-protein binds to AEC-2 cells initiates cytokine storm followed by amplified NF-κB pathway, and oxidative stress. Elevated activation of this pathway increases Snail, Slug, Twist expression that leads to EMT. Moreover, increased ROS production creates fibrotic environment in lung. This review examined the mechanism behind the pulmonary fibrosis by analyzing interplay between the SARS-CoV 2 infection and EMT, providing effective therapeutic strategies to prevent EMT.}, }

During the outbreak, medical regulatory authorities introduced several principles for outbreak control, with the World Health Organization emphasizing three key strategies: prevention, early detection, and treatment. In this context, technological advancements have played a critical role, particularly nanotechnology, which has emerged as a promising platform for medical innovation. Its applications span multiple sectors, including healthcare, environmental protection, and diagnostics. These applications offer unmatched potential to enhance personal protective equipment, develop antiviral surface coatings, and engineer rapid point-of-care diagnostics. Nanotechnology contributed significantly to combating COVID-19, enhancing prevention through nanofiber-enhanced masks and nanoparticle-based disinfectants; facilitating diagnosis via gold nanoparticles (AuNPs) and magnetic nanoparticle biosensors, quantum dots, and artificial intelligence-integrated nanosensors; and supporting treatment efforts through lipid nanoparticle (LNP) vaccines, virus-like particles, and targeted drug delivery systems. We highlight key nanomaterials such as silver nanoparticles, copper nanoparticles, AuNPs, zinc oxide nanoparticles, and selenium nanoparticles, alongside advanced formulations like LNPs and polymeric nanocarriers, exploring their mechanisms of viral inactivation, sensitive detection, and controlled delivery of therapeutics. Furthermore, this review addresses critical regulatory and translational challenges and post-pandemic adaptations of nanotechnologies for emerging viral threats.}, }

This review critically examines the double-edged nature of POCT, balancing its clear clinical and operational advantages against persistent challenges of accuracy, quality assurance, governance, and cost-effectiveness. The scope of POCT technologies ranges from simple lateral-flow assays to advanced molecular platforms, increasingly integrated with digital health ecosystems. Their clinical utility is evident in emergency medicine, chronic disease management, and resource-limited settings, where timely results reduce delays, hospital stays, and downstream complications, while supporting personalized and preventive care. The COVID-19 pandemic further highlighted the flexibility and scalability of POCT during public health emergencies. However, these benefits are countered by risks of variable analytical performance, inadequate training of non-laboratory operators, fragmented data integration, and economic trade-offs from high per-test costs and potential overuse. Governance frameworks-anchored in ISO 22870 (and now ISO 15189:2022), rigorous quality management, connectivity solutions, and multidisciplinary oversight-are essential to ensuring safe, effective, and sustainable implementation. Successful programs demonstrate that strong laboratory leadership, continuous training, and robust data integration mitigate risks while maximizing impact. Ultimately, POCT should be viewed not as a replacement but as a complement to central laboratory services, whose value is realized only through thoughtful deployment and governance. With advancing technology and improved oversight, POCT can be harnessed as a powerful adjunct in modern healthcare, turning its double-edged potential into a precise tool for patient-centered diagnostics.}, }

We included observational studies with raw data of adherence to handwashing (rates of acceptability of handwashing, daily habitual handwashing and key-moment handwashing) during VRID pandemics/epidemics. Pooled rates and effect of handwashing were calculated by random-effects model and generalised linear model.<br><br>RESULTS: We analysed 108 articles, generating 227 datasets. During VRID epidemics/pandemics, the global pooled rate of daily handwashing was 72.23% (95% CI 66.95% to 76.95%). The lowest rate was observed in Africa (pooled rate 59.46%, 95% CI 50.73% to 67.68%) and among public transportation workers (18.15%, 95% CI 6.54% to 41.26%). Global pooled rate of key moment handwashing was 65.11% (95% CI 59.74% to 70.28%), with the lowest rate being after handshaking (36.40%, 95% CI 18.49% to 56.52%) and among the elderly (22.86%, 95% CI 16.77% to 29.58%) and was higher during the COVID-19 pandemic than the 2009 H1N1 pandemic (72.02% vs 31.33%). The pooled rate of global acceptability of handwashing was 90.01% (95% CI 83.73% to 94.05%).

In African societies, solidarity is rooted in the relational philosophy of ubuntu, where individual identity is understood as inseparable from the community, emphasising collective well-being and mutual care. This is reflected in practices, such as community-based caregiving for the sick and elderly, traditional healing networks and shared child-rearing. In parts of West Africa, for example among the Igbo, co-wives may sleep over at the home of a bereaved wife to provide emotional support and boost morale during mourning.In contrast, European models of solidarity are often institutionalised and rights-based, focusing on balancing individual autonomy with collective welfare within legal frameworks. This paper explores these two distinct approaches to solidarity and examines their implications in global health, especially in the context of the COVID-19 pandemic and other global health crises. Ubuntu's emphasis on communal responsibility offers a valuable framework for addressing health inequities, suggesting that global health is a shared responsibility that transcends national borders and individual interests. Conversely, European solidarity, shaped by enlightenment principles and liberal democratic traditions, often prioritises individual rights and institutional mechanisms to ensure health equity. This dialectical exploration highlights the evolving nature of solidarity in a globalised world, where African and European models of solidarity are increasingly hybridised to address global health disparities. Drawing on examples such as the Ritshidze community-led HIV care monitoring initiative in South Africa, alongside international efforts like COVAX, this paper evaluates how solidarity, in both its African and European forms, can influence global health policy and collective action, promoting more inclusive and equitable health systems worldwide.}, }

Based on clinical observations, it has been revealed that the virus can easily disturb the function of various organs in the body. Besides its main damage to the respiratory system, the extra-pulmonary manifestations are deemed to be common in affected patients even after COVID-19 vaccination. COVID-19 has been accompanied by various types of skin manifestations, including varicella-like exanthemas, dengue-like petechial rashes, or urticarial eruptions. However, not only have viral rashes been related to COVID-19, but also other types of skin symptoms that are reminiscent of a vascular disease, such as acro-ischaemic lesions. This literature review aims to provide information on various forms of COVID-19-induced vasculitis and vasculitis following vaccination. It has been hypothesized that various forms of vasculitis can be considered as pathological consequences following SARS-CoV-2 infection. Numerous suggested mechanisms are involved in vasculitis, including the deregulation of the immune system, increased activation of mastocyte, augmented production of proinflammatory cytokines, which in turn lead to indirect endothelial damage, complement system activation, recruitment of neutrophils, and deposition of immune complexes. Based on previous studies, the mRNA-based COVID-19 vaccine is much more implicated in relation to vasculitis. SARS-CoV-2 and COVID-19 vaccination lead to the onset and relapse of different types of vasculitis that should be clinically evaluated by exact monitoring.}, }

This study examines and analyzed South Korea's hospice response policies during the pandemic. It draws on empirical data from domestic and international literature reviews and relevant websites. This study aimed to provide foundational data and policy recommendations for future pandemic preparedness. The findings revealed that, owing to the national response policy focused on infectious disease control and hospital bed allocation, 21 of the 88 inpatient hospice units in South Korea were closed, with their beds repurposed Therefore, hospice palliative care services became a "negotiable service" largely excluded from pandemic response policies. Strict visitation policies lowered hospice service utilization and disrupted service continuity. Emergency care support helped to mitigate care gaps; however, hospice care was limited in addressing patients' specialized needs, demonstrating structural fragmentation within the health and welfare systems.

Diverse clinical manifestations, chronic course, and incompletely understood pathophysiology-including hypotheses involving viral persistence, immune dysregulation, autoimmunity, endothelial dysfunction, and metabolic reprogramming-impede the development of diagnostic criteria, biomarkers, and targeted therapies. We conducted a critical review of 101 Long COVID omics studies, focusing on the computational methods used and their methodological quality. Using standardized criteria, we evaluated study design, statistical rigor, reproducibility, and clinical relevance across genomics, epigenomics, transcriptomics, proteomics, metabolomics, and multiomics integration, and mapped these findings onto regulatory and translational frameworks. Despite substantial methodological heterogeneity, convergent biological signals emerged. Genomic studies implicate risk loci in immune and cardiopulmonary pathways. Epigenomic analyses identify differentially methylated regions in immune and circadian genes. Transcriptomic studies reveal persistent dysregulation of innate immune and coagulation pathways, as well as reproducible molecular endotypes. Proteomic studies consistently show abnormalities in the complement cascade and coagulation, with a small panel of complement proteins showing highly reproducible changes across independent cohorts. Metabolomic studies demonstrate sustained mitochondrial dysfunction and altered cellular bioenergetics for up to two years after infection. Multiomics integration supports at least two major endotypes, characterized by predominant inflammatory versus metabolic dysregulation, and provides a basis for patient stratification and computational treatment discovery. Machine learning models frequently achieve high classification performance, but are rarely externally validated. Critical limitations restrict clinical translation. Most studies are underpowered relative to analytical complexity, use heterogeneous case definitions and controls, and report platform-specific signatures with limited overlap. External validation, preregistered analysis plans, and regulatory-aligned assay development are uncommon. To date, no regulatory-approved diagnostic assay or evidence-based therapeutic intervention has directly emerged from these computational findings. Future progress requires harmonized phenotyping protocols, adequately powered longitudinal cohorts with external validation, integration of spatial omics and explainable artificial intelligence, and early engagement with regulatory and health-technology assessment pathways. This review provides a critical assessment and a translational roadmap, outlining how methodologically robust computational omics can be advanced toward clinically actionable tools for Long COVID.}, }

Many innate and adaptive immune functions of DCs are regulated by cathepsins, proteolytic enzymes primarily found in acidic endolysosomal compartments. Different DC subsets exhibit distinct cathepsin expression patterns, influencing their functional capacities and interactions with viruses. In DCs, cathepsins contribute to virus sensing through innate receptors, regulate cytokine production and DC migration, and are essential for viral antigen degradation and loading onto MHC molecules for T-cell activation. Many viruses, however, have evolved mechanisms to alter cathepsin expression and activity, thereby subverting DC function and promoting their own persistence. Indeed, cathepsins can facilitate viral entry into DCs, promote viral replication, and support immune evasion strategies. In this review, we summarize recent advances in understanding the role of cathepsins in DC-virus interactions, emphasizing both how DCs exploit cathepsins to generate protective immune responses and how viruses manipulate cathepsin activity to their advantage. We particularly focus on clinically relevant viral pathogens, including HIV, influenza virus, hepatitis C virus, human cytomegalovirus, Ebola virus, and SARS-CoV-2, to illustrate the multifaceted influence of cathepsins on DC biology during viral infection.}, }

Advances in next-generation sequencing have transformed mycobiome research, revealing fungal diversity and its impact on health and disease. This review examines the mycobiome's composition and function across major body sites, including the gut, mouth, lungs, reproductive tract and skin. It also explores connections between fungal imbalances (dysbiosis) and diseases such as neurological disorders, cancer and post-COVID-19 complications. Despite progress, challenges persist, including the need for better culture-independent diagnostic tools and standardized research methods. Combining culturomics and metagenomics could help overcome these limitations and identify new treatment targets.

Among these, the - 216G/T (rs712829) single nucleotide polymorphism (SNP), located in the EGFR promoter region, is gaining attention for its potential clinical relevance. This narrative review aims to provide a comprehensive chronological overview of the discovery, functional implications, clinical relevance, and broader oncological and non-oncological associations of the EGFR - 216G/T SNP. Relevant studies were identified from 2005 to 2025 through literature searches across publicly available databases and bibliographies of key publications. This SNP was associated to increased EGFR promotor activity, pleural metastasis, susceptibility to EGFR mutations, NSCLC risk, and different inter-individual and inter-ethnic allele frequencies. Conflicting findings regarding survival outcomes and toxicity underscore the need for further validation. Beyond NSCLC, this SNP has demonstrated relevance in colorectal cancer, glioma, breast cancer, cardiovascular disease, and even COVID-19 susceptibility. The - 216G/T polymorphism represents a promising germline biomarker for NSCLC susceptibility.

Methods: We systematically searched PubMed, Scopus, ScienceDirect, Web of Science, and CINAHL for studies published between January 2020 and July 2025. Eligible studies reported mean and standard deviation values for job satisfaction among physicians and nurses in healthcare settings across the specified timeframes. Studies were excluded if they assessed other types of satisfaction or combined data across COVID periods. Pooled standardized mean difference (SMD) was calculated using random-effects models in R. Results: Before COVID-19, the SMD was -2.40 (95% CI -8.05 to 3.26; I[2] = 98%). During the pandemic, the estimate was 1.39 (95% CI -0.57 to 3.35; I[2] = 91.5%), and post-pandemic, it remained small (SMD = 0.29; 95% CI -1.63 to 2.22; I[2] = 95.8%). Emergency care during COVID showed a significant advantage for physicians (SMD = 0.29; 95% CI 0.05 to 0.52; I[2] = 0%). Post-COVID, mixed settings slightly favored physicians (SMD = 0.06), while primary care favored nurses (SMD = -0.30); subgroup differences were significant. Conclusions: The findings reveal that job satisfaction is not solely determined by professional role but is significantly influenced by temporal and contextual factors. Job satisfaction is shaped more by temporal and contextual factors than by professional role. While no consistent differences were observed pre-pandemic, emergency care favored physicians during COVID, and post-pandemic trends showed modest advantages for nurses in primary care and physicians in mixed settings. Due to the methodological limitations of this meta-analysis, including high heterogeneity, reliance on cross-sectional data, and very low/low certainty of evidence, these results should be interpreted with caution.}, }

Videoconferencing can support social connections, but the role of aging-in-place organizations (AIPOs), such as senior centers and Area Agencies on Aging, in facilitating adoption is poorly understood. This review examined how AIPOs use relational videoconferencing to promote social engagement among older adults. Methods: We applied a hybrid methodology combining a scoping review with latent topic modeling to contextualize and analyze the evidence base. Exploratory searches revealed limited literature specifically addressing AIPO involvement; therefore, we first conducted latent topic modeling of the broader literature on social videoconferencing among older adults to establish a thematic foundation for the subsequent PRISMA-guided scoping review. Thematic analysis of this broader corpus, identified through 2021 database searches, applied Latent Dirichlet Allocation (LDA) to a collection of peer-reviewed articles. Subsequent refinement of this corpus by removing non-primary research and non-AIPO records produced the narrower PRISMA subset used for the scoping review. The scoping review followed JBI guidelines and was based on database searches (EBSCOhost: MEDLINE, AgeLine, SocINDEX, Health Source: Nursing/Academic Edition, and Family &amp; Society Studies Worldwide; ProQuest Social Science Premium Collection; and PubMed, including MEDLINE, PMC, and in-process content) for peer-reviewed studies published between 2011 and 2025. Inclusion criteria required primary research involving adults aged 65 years or older, use of videoconferencing technology for social engagement, and reference to AIPOs or analogous community-based aging services. The protocol was post-registered with the Open Science Framework. Results: The LDA analysis of 101 peer-reviewed articles identified six latent themes describing the broader research landscape: problem of isolation, character of socialization, physical health, technology as intervention, technology as social medium, and supportive environments. This thematic framework informed the scoping review, which screened 1908 records and retained 25 publications (representing 24 unique studies) explicitly referencing AIPO involvement in relational videoconferencing. Only one study predated COVID-19. Mapping these studies to the LDA-derived themes revealed the least consistent coverage to be in supportive environments and physical health, particularly among AIPOs other than senior or community centers. Conclusions: Relational videoconferencing has potential to sustain and expand older adults' social connections, but evidence mapped through the scoping review shows that documentation of how AIPOs support adoption is sparse. The hybrid approach advances understanding of videoconferencing in aging contexts and identifies priorities for documenting, comparing, and refining AIPO practices to inform future interventions and policy.}, }

A Scoping Review.}, journal = {Healthcare (Basel, Switzerland)}, volume = {13}, number = {23}, pages = {}, pmid = {41373396}, issn = {2227-9032}, abstract = {Background/Objectives: Trauma-related distress poses significant mental health challenges, with psychotherapy serving as a primary intervention. The Walters Method is a promising new alternative that may help where traditional methods fall short (i.e., in complex or violent cases), but before it can be implemented widely, the existing evidence on the effectiveness of other psychotherapies for trauma-related distress must be mapped to see how and where it relates to other techniques. The aim of this scoping review was to provide an overview of existing evidence on the effectiveness of psychotherapy for trauma-related distress. Methods: A scoping review was conducted to better understand the effectiveness of psychotherapies for trauma-related distress (including PTSD, acute stress disorder, or other serious mental health issues). Results: Thirty-three articles were analysed. Included articles included adults with PTSD, incarcerated women, childbirth trauma survivors, female survivors of sexual abuse, hospitalised COVID-19 patients, adults with serious mental illness, veterans and active soldiers, firefighters, and refugees. Eye Movement Desensitisation and Reprocessing and Cognitive Behavioural Therapy were the most studied and effective treatments. Prolonged Exposure and Narrative Exposure Therapy were less common but noteworthy. Other therapies, including psychodynamic approaches, are seldom studied but have proven effective when explored, highlighting knowledge gaps and potential missed opportunities. Success with these alternative approaches-especially in complex trauma cases like intimate partner violence or child loss where EMDR and CBT may be less effective-suggests they have potential, but further research is needed for validation. Conclusions: This review offers novel contributions to the field by emphasising innovative therapeutic perspectives that extend beyond traditional, more studied, evidence-based approaches such as CBT and EMDR, thereby expanding treatment options for diverse clinical presentations. Alternative therapies show promise, particularly for complex trauma cases like intimate partner violence or child loss where established approaches may be less effective; however, further research is needed to validate their efficacy across diverse populations. Selection of psychotherapy should be based on clients' goals and comfort, and the cultural and contextual compatibility between the person and intervention. Future research should prioritise underexplored therapies to address current knowledge gaps and improve treatment accessibility for varied clinical needs.}, }

Resveratrol, a natural polyphenol with antiviral, anti-inflammatory, and microbiota-modulating properties, has been proposed to interrupt this pathogenic feedback. To our knowledge, this is the first narrative review focused on resveratrol's antiviral activity in pediatric viral infections, concurrently evaluating its impact on the gut microbiota and their interrelationship. We synthetized preclinical and the limited available pediatric clinical data regarding resveratrol's effect on SARS-CoV-2, respiratory syncytial virus, influenza, rotavirus, and norovirus, extracting information on the models, routes of administration, dosages, mechanisms, and outcomes. Resveratrol interferes with viral lifecycles via diverse mechanisms (modulation of host signaling cascades, capsid or structural protein interactions, and suppression of pro-viral chaperones) while concurrently reshaping the gut microbiota (reducing opportunistic taxa and enriching beneficial genera such as Bifidobacterium and Lactobacillus) leading to improved short-chain fatty acid profiles, barrier integrity, and dampened inflammation. Intranasal resveratrol in children shows clinical benefit, while oral use is underexplored and limited by poor bioavailability; adult data hint at supportive microbiome and anti-inflammatory effects if the delivery is optimized. These dual antiviral and microbiome-directed effects position resveratrol as a promising adjunct in pediatric viral disease management, though well-powered pediatric clinical trials are needed to define dosages, delivery strategies, and the contribution of microbiota-mediated synergy.}, }

The aim of this narrative review is to integrate current evidence on the molecular and cellular mechanisms underlying chronic neuroinflammation following viral infections, with a focus on dysregulated innate immune responses, macrophage-microglia interactions, oxidative-mitochondrial stress, and impaired inflammation resolution pathways. Our synthesis shows that prolonged activation of macrophages and glial cells promotes the continuous release of pro-inflammatory mediators, while defective phagocytosis and inadequate clearance of cellular debris maintain an inflammatory microenvironment. Mitochondrial dysfunction further amplifies immune activation by stimulating metabolic stress and reactive oxygen species production. In parallel, deficiencies in mediators specialized in inflammation resolution impede the transition from inflammation to resolution, allowing neuroimmune imbalance and nociceptive sensitization to persist long after virus clearance. Key conclusions indicate that these interconnected mechanisms collectively contribute to the long-term neurological symptoms observed in post-viral states, including cognitive impairment, neuropathic pain, and fatigue. Emerging therapeutic strategies targeting cytokine signaling, microglial reactivity, mitochondrial function, and resolution pathways are promising, but remain insufficiently validated in clinical practice. Overall, evidence suggests that post-viral neuroinflammation results from the convergence of sustained immune activation and failure of endogenous resolution mechanisms, highlighting the need for further mechanistic studies and targeted interventions.}, }

Methods: Current Mg studies report ratios between serum Mg and calcium (Ca) using four interchangeable expressions (i.e., molar or weight calculations of Mg/Ca or Ca/Mg). We propose a scale using ratios of serum Mg and Ca to assess Mg status, unified for all four expressions. We explore its application for case studies and published research. Results:Case Studies (4)-the proposed serum Mg/Ca scale showed better Mg diagnostic value than serum Mg alone. Published Studies-A. The proposed Mg/Ca scale's "depleted Mg" status predicted mortality among hospitalized COVID-19 patients in ROC/AUC analyses. B. The serum Ca/Mg proposed scale, when applied to "healthy" adults with "normal" serum Mg, exposed a "seriously depleted" to "adequate" range of Mg status. C. In a study of periodontal disease, patients designated "adequate" or "mild" Mg depletion by the proposed scale showed greater 5-year improvement than those with scale's "moderate to serious" Mg depletion status. D. Finally, the proposed scale demonstrated appropriate diagnostic value of serum Ca/Mg in acute coronary syndrome patients only when "corrected Ca" was NOT used in ratio calculation. Conclusions: The proposed scale needs both total serum Ca and Mg measures in identical units, i.e., mg/dL or mg% (for weight ratios); mmol/L or mEq/L (for molar ratios). Authors/reviewers/editors need to take care when reporting units/methodology of serum Mg and Ca ratios for clear reporting as to weight or molar ratio and use of total or corrected values. Future trials and statistical testing are needed to determine whether ratios between serum Mg and Ca yield more precise measures of physiological Mg status than serum Mg alone. Our findings indicate the proposed scale is worthy of further study as a marker of Mg deficit.}, }

This interdisciplinary review critically examines how these disruptions have influenced both food approach and food avoidance patterns, offering a structured analysis of eight key behavioral parameters: Hunger (H), Food Responsiveness (FR), Emotional Overeating (EOE), Enjoyment of Food (EF), Satiety Responsiveness (SR), Emotional Under Eating (EUE), Food Fussiness (FF), and Slowness in Eating (SE). Drawing on recent literature, we highlight significant shifts in these traits-such as heightened hedonic hunger, age-related changes in food preferences, and gender-specific emotional-satiety dynamics-underscoring the complex interplay between emotional states, physiological cues, and behavioral tendencies. Grounded in the systematic examination of peer-reviewed studies in the post-COVID period, this review offers a robust and comprehensive synthesis of current evidence. The novelty of this work lies in its integration of findings into targeted proposition statements for each parameter, visually supported by original flow charts. These culminate in the development of a "Consumers' Eating Behavior Index"-a conceptual tool designed to guide researchers, healthcare professionals, and policymakers in understanding and responding to post-pandemic dietary transformations. By emphasizing the emotional and psychological dimensions of eating, this index offers a timely framework for designing tailored public health interventions that promote sustainable nutritional habits.

Being considered vulnerable and at risk of infection, cancer patients have been prioritized for COVID-19 vaccination and vaccinated repeatedly because of the short time protection provided by these vaccines. Recently, a surge in the incidence and rapid progression of cancers has been observed in many countries, which could (at least partially) represent cancers undiagnosed or untreated during the pandemic. It has also been suggested that the SARS-CoV-2 itself or even the anti-COVID-19 mRNA vaccines could have contributed to the recurrence and worse clinical outcome in cancer patients, given the high incidence of COVID-19 in hospitalized patients and that these patients have been vaccinated with priority several times and in a short period. Although it appears extremely unlikely that SARS-CoV-2 and anti-COVID-19 mRNA vaccines elicit genotoxic events and cause neo-cancerogenesis in a short time, they could still cause non-genotoxic pro-carcinogenic effects by triggering an exaggerated inflammatory reaction, compromising immune homeostasis, stimulating cell proliferation, and negatively affecting cellular stress response and damage repair machinery. This could result in the promotion of regrowth of dormant micrometastases or relapses of stable minimal residual disease. Such a harmful outcome may likely result from a synergy between the virus and the vaccine, especially in multi-vaccinated and multi-infected individuals. Here, I bring the cell pathologist's point of view and discuss the multiple possible mechanisms by which the virus and the anti-COVID-19 mRNA vaccine might favor tumorigenesis. While a causal link cannot be established at this stage, knowledge of potential carcinogenic risks could help doctors and health policymakers take the best actions to protect vulnerable patients and convince the vaccine developer to design a vaccine free from such harm.}, }

This umbrella review aimed to synthesise review-level evidence on the impact of the COVID-19 pandemic on QoL across the general population, including children, adolescents, adults, and older people. Methods: A systematic search of databases (MEDLINE (PubMed); EBSCOHost; Scopus; Google Scholar) and review repositories was conducted to identify systematic reviews, meta-analyses, and scoping reviews published between 2019 and 2025. Eligible reviews (2019-2025, English, peer-reviewed) included narrative, systematic and meta-analytic syntheses of quantitative, qualitative or mixed-methods evidence examining the impact of the COVID-19 pandemic on quality of life in the general population, using validated QoL measures. The review followed Joanna Briggs Institute methodology for umbrella reviews, with data synthesised narratively by QoL domain and population group. Results: Nine reviews met the inclusion criteria, encompassing 272 primary studies. Most reported declines in QoL across psychological, physical, and social domains. Children and adolescents experienced reductions in emotional and social functioning. Working-age adults reported psychological strain linked to economic and health-related stressors, while older adults were vulnerable to isolation and reduced social QoL. Environmental and structural factors also influenced QoL. Sociodemographic disparities were observed, with lower QoL reported among women, younger individuals, and those with lower socioeconomic status.

Limited evidence is available concerning the surgical outcomes of patients with congenital gastrointestinal malformations and perioperative SARS-CoV-2 infection. This study examines the scientific evidence on SARS-CoV-2 infection and congenital gastrointestinal malformations requiring surgery in children. Material and Methods. We performed a systematic review of studies reporting data on children with congenital gastrointestinal malformations and SARS-CoV-2 infection, published in international databases (PubMed and Embase) from pandemic inception up to August 2024. Studies not reporting data on the SARS-CoV-2 infection status on patients with congenital digestive malformation were excluded. We assessed the quality of the included studies according to the Joanna Institute (JBI) appraisal checklist, adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines, and registered the protocol with the PROSPERO database (CRD42024550744). Results. From the 902 titles retrieved, eight observational studies met the inclusion criteria comprising 29 patients from countries with different socioeconomic statuses. Most patients were neonates (75%) with a median age of 3 days at diagnosis and male to female ratio of 2:1. In total, 18 (62%) presented upper gastrointestinal tract anomalies, including esophageal atresia ± tracheoesophageal fistula (n = 10, 34.48%), duodenal atresia (n = 3, 10.3%), and congenital hypertrophic pyloric stenosis (n = 5, 17.2%). Lower digestive tract malformations (11, 38%) included anorectal malformations (n = 6, 20.6%), intestinal atresia (n = 3, 10.3%), Hirschsprung disease (n = 1, 3.44%), and Meckel's diverticulum (n = 1, 3.44%). Surgeries were primarily emergency or urgent procedures and only pyloromyotomy (5/5) was consistently operated minimally invasively. SARS-CoV-2 infection was identified mainly on routine screening (>95%). Of 29 patients, 85% were discharged home, and no postoperative surgical mortality and significant complications directly associated with COVID-19 were identified, although routine postoperative morbidity not linked to SARS-CoV-2 was observed. Conclusions. Pediatric patients with congenital gastrointestinal malformationsand perioperative SARS-CoV-2 infection typically have mild illness and favorable surgical outcomes. SARS-CoV-2 positivity alone should not delay essential surgery when infection control measures are ensured. Standardized, multicenter studies are needed to clarify perioperative risks to and inform management of this high-risk group.}, }

The percentage of neutrophils (&#x2265;50%) was higher than that of lymphocytes/monocytes [12/26 (46.2%) vs. 7/26 (26.9%), respectively]. Polymerase chain reaction (PCR) on PF was positive for SARS-CoV-2 in 6/23 cases (26.1%) and for other pathogens in 8 (5 bacteria and 3 fungi). Almost all patients underwent thoracentesis and the medical treatment received by the cases with positive PCR for SARS-CoV-2 on PF varied.

This study provides a systematic review of the literature on the relationship between domain-specific self-efficacy and motivation among university students, adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. From an initial pool of 5,890 articles sourced from the Education Resources Information Centre (ERIC), Scopus, and Web of Science (WoS) databases, 31 studies published between 2019 and 2024 were analyzed. Our findings underscore a predominantly positive correlation between domain-specific self-efficacy and motivation. Higher levels of self-efficacy are consistently linked to increased motivation, suggesting that enhancing self-efficacy could be a crucial strategy for boosting student motivation and, thus, academic success. Notably, many studies focus on Asian regions, highlighting both the universality and cultural specificity of these findings. However, the presence of an outlier study that found no significant relationship between self-efficacy and motivation indicates the complexity of these constructs and the potential impact of situational factors, warranting further investigation. Additionally, this review reveals a growing academic interest in self-efficacy and motivation, particularly within social sciences and education. This trend underscores the importance of a multidisciplinary approach to understanding the intricate dynamics between self-efficacy and motivation. The documented rise in research attention reflects a growing recognition of the critical role that self-efficacy and motivation play in student learning outcomes. In conclusion, this systematic review not only highlights the significant positive impact of domain-specific self-efficacy on student motivation but also calls for more nuanced studies. Future research should explore under-represented contexts and examine the broader implications of these findings across diverse educational and cultural settings.}, }

This review comprehensively synthesizes the recent advancements in mRNA cancer vaccine development, emphasizing three critical domains: mechanistic innovations, clinical translation, and ongoing challenges. Technologically, advancements in nucleotide modification, lipid nanoparticle (LNP) delivery systems, and AI-driven neoantigen selection have significantly improved vaccine stability, immunogenicity, and personalization. Clinically, more than 150 trials have demonstrated the synergistic efficacy of mRNA vaccines (e.g., mRNA-4157/V940, BNT122) in combination with immune checkpoint inhibitors (ICIs), particularly in melanoma, with Phase III trials currently underway. Individualized neoantigen vaccines targeting patient-specific mutations have shown unprecedented response rates (> 50% in certain cohorts), while shared-antigen vaccines are progressing for high-incidence cancers. However, several critical challenges remain: (1) overcoming immunosuppressive tumor microenvironments (TME), (2) addressing systemic toxicities and LNP-related limitations, (3) scaling up cost-effective personalized manufacturing, and (4) optimizing targeted delivery. Future research directions encompass self-amplifying mRNA constructs, novel biomaterial vectors, neoadjuvant applications, and multi-omics integration for next-generation vaccine development. With rapid industrialization and evolving regulatory frameworks, mRNA vaccines are well-positioned to revolutionize precision cancer immunotherapy despite persistent translational barriers.}, }

SC administration offers multiple benefits, including potential for at-home administration, enhanced patient compliance, reduced hospital congestion, lowered health care costs, and improved sustainability by reducing drug wastage and minimizing environmental impact. However, for many biologics, the shift to SC administration requires the development of high-concentration monoclonal antibody products (HCmAP) due to the need for large dose volumes. Here we explore the impact of the COVID-19 pandemic on immunotherapy administration and the imperative of adopting SC administration. We discuss challenges encountered throughout the manufacturing, shipping, storage, and delivery of HCmAP. A central hurdle identified involves the biophysical instability and the large increase in viscosity of these biologics due to increased antibody concentration. Further complications can arise from "non-ideality" effects through molecular crowding or co-exclusion effects (macromolecules blocking the free movement in solution of other macromolecules) and elevated macromolecular interactions. For reducing the viscosity for a given concentration of antibody, the main excipients reported are salts and amino acids, with Arg-HCl demonstrating particularly improved formulation viscosity in an HCmAP. However, excipients with viscosity-lowering effects can also impact protein stability. The journey to discover suitable excipient strategies remains ongoing, combined with emerging approaches such as molecular engineering and computational techniques, with the ultimate aim of facilitating the successful integration of SC administration for economic savings, environmental sustainability, and social equity.}, }

Here, three UK labs made crucial contributions revealing how the spike protein targets human cells and how therapies of vaccines and neutralising nanobodies work, enabled largely through biophysical innovations of cryo-electron microscopy. Here, we discuss leading-edge innovations which resulted from discovery-led British "Physics of Life" research (capturing blends of physical-life sciences research in the UK including biophysics and biological physics) and have matured into wide-reaching sustainable commercial ventures enabling translational impact. We describe the biophysical science which led to these academic spinouts, presenting the scientific questions that were addressed through innovating new techniques and approaches. We consider these examples through the lens of opportunities and challenges for academic biophysics research in partnership with British industry. We highlight how commercial breakthroughs have emerged organically from fundamental research rather than from technology-first approaches but also discuss lessons to learn from past failures. Finally, we propose recommendations concerning future resourcing and structuring of UK biophysics research and the training and support of its researchers to ensure that UK plc punches above its weight in biophysics innovation and a need to educate the policymakers and public that an absence of basic science impoverishes innovation.}, }

This destruction is primarily driven not by the bacteria themselves, but by the host's dysregulated immune response to a dysbiotic subgingival biofilm. Bacterial colonization in periodontal disease (PD) triggers both innate and adaptive immune responses. Furthermore, numerous viruses-including human cytomegalovirus (HCMV), Epstein-Barr virus (EBV), and herpes simplex virus (HSV)-have been linked to periodontal disorders and contribute to the etiopathogenesis of periodontitis alongside bacteria. Since its emergence in 2020, COVID-19 has posed a significant global health threat. SARS-CoV-2 infection within the periodontium may induce local inflammation, potentially exacerbating PDs. Given that viral replication and persistence in tissues are thought to increase with the severity of inflammation, the presence of these viruses may be linked to the development and progression of periodontitis. The current study is unique in its synthesis of data on a wide spectrum of viruses associated with periodontitis.

PRP occurred both after the first dose (14/30, 46.6%) and at subsequent doses of the vaccine. The majority of patients re-exposed to new doses (6/9, 66%) experienced clinical exacerbation. Post-vaccination PRP responds well to both traditional and biologic treatments, with only 4/30 (13.3%) showing no resolution.<br><br>CONCLUSIONS: In conclusion, PRP post-vaccination is rare and likely underdiagnosed, but recognizing the association is important to evaluate any new exposures to the trigger. A thorough patient history, including recent vaccinations, is crucial.}, }

The aim of this review is to summarize these aspects for pediatric pulmonologists. Narrow nasal passages, a small pharynx and larynx, in combination with relative macroglossia, other airway malformations, and generalized muscular hypotonia, lead to glossoptosis, which in very young infants frequently causes obstructive sleep apnea syndrome. If left untreated, this is associated with impaired cognitive development. The children also suffer from chronic rhinitis. Together with recurrent silent aspirations resulting from the typical dysphagia of children with Trisomie 21 and immune dysregulation, lower respiratory tract infections are common and often severe. Viral infections caused by RSV, influenza, and SARS-CoV-2 more frequently lead to hospitalizations and have a much higher mortality rate than in healthy children. Children with Down syndrome are also more likely to develop chronic wheezing. The development of pulmonary hypertension may rarely occur even without an associated heart defect.

The impact of poor preparedness on the health, social, and economic effects of the 1918 influenza pandemic, the 2001 anthrax attacks, and the COVID-19 crisis is devastating. Standard methods, such as quarantine and serology, as well as traditional inoculations, offered basic defences but were often reactive, slow, and unfair. The recent scientific and technological progress has altered the concept of biosecurity preparedness by providing new instruments of early detection, quick reaction, and fair health solutions. Artificial intelligence-based epidemic prediction, next-generation sequencing, CRISPR-based diagnostics, and digital epidemiology are emerging technologies that enable near-real-time surveillance. New therapeutic agents and vaccines, such as mRNA and DNA platforms, monoclonal antibodies, and nanobody therapies, have enhanced response capabilities. Containment measures based on robotics, biosensors, nanotechnology-based PPE, and portable biocontainment units have simultaneously improved frontline safety. Sensitive health information and enhanced coordination are today secured with the help of digital and cyber-biosecurity tools. Nonetheless, the innovations have ethical, legal, and equity issues, which point to the need to govern responsibly and make them accessible to all. This review brings forth the incorporation of emerging technologies with international cooperation, fair systems, and responsive policies as the keys to developing resilient and future-orientated systems that could help alleviate natural, accidental, and intentional biosecurity threats.}, }

Here, we argue that epistasis-where the phenotypic effects of mutations or gene variants are dictated by the presence of other mutations or genes-should become a focus of genomic epidemiology. To demonstrate this, we present the results of a systematic review of the literature on epistasis in viruses, focusing on three major human viral systems: (i) influenza, (ii) SARS-CoV-2, and (iii) human immunodeficiency virus, as well as two other bodies of the literature mainly focusing on nonhuman viruses: (iv) tobacco etch virus and (v) experimental evolution of viruses. Our systematic review of these five bodies of the literature highlights that epistasis is prevalent in host-virus systems of various kinds, manifesting within and between different loci, with effects of different magnitudes and directions, and shaping various phenotypic traits of epidemiological interest. At the same time, our systematic review demonstrates that our ability to draw general conclusions about the direction and magnitude of epistasis in viral evolution is constrained by several factors: the idiosyncrasies of virus-host systems, biases in the underlying data collection exercises, and the limitations of existing methods. Moving forward, we encourage collaborations between genomic epidemiologists and evolutionary biologists to identify and measure epistasis in studying the evolution of viral pathogens.}, }

Data extracted included telemedicine medium used, accuracy of diagnosis, cost, impact on patient transfer volume, and timeline for assessment. Study quality was assessed using the MINORS scale.ResultsOf the 15 included studies, eight assessed diagnostic accuracy, four evaluated cost savings, four examined patient transfers, five reported on efficiency, and three investigated access to care.

Commonly referred to as agroinfiltration, scaled-up versions of this manufacturing process have now become helpful in the fight against global health issues, such as those rapidly evolving virus strains causing influenza or coronavirus disease 2019. In the past decades, considerable efforts have been deployed to improve the efficacy of Agrobacterium-mediated expression, including through the development of new binary vectors, the design of strong promoters, and the deployment of approaches to increase levels and stability of transgene mRNAs. By comparison, much less attention has been given to understanding the effects that agroinfiltration unavoidably has on host plants, including the infiltration process itself, the perception of Agrobacterium and the subsequent accumulation of recombinant products throughout the expression phase.

Thematic analysis of our review revealed that mental health disorders now affect nearly one in eight people worldwide, yet up to 75% of those in LMICs receive no treatment due to stigma, underfunding, workforce shortages, and fragmented systems, perpetuating a widening "treatment and care gap." Social inequities, harmful cultural norms, conflict, climate change, and gender disparities further amplify the risk and economic burden, projected to exceed US$6 trillion by 2030. Innovative financing approaches, including public-private partnerships and models from countries such as Norway and Australia, offer promising strategies for sustainable investments. The COVID-19 pandemic intensified mental health challenges but also raised global awareness, with leaders such as the United Nations Secretary-General and the United States Surgeon General foregrounding mental health crises in the public consciousness. Advocacy initiatives, including the FundaMentalSDG campaign, Lancet Commissions, Global Mental Health Action Network, and Global Mental Health Peer Network, have been pivotal in elevating mental health within the Sustainable Development Goals (SDGs) and linking it to social determinants. Emerging solutions include rights-based frameworks that emphasize participation and anti-discrimination, scaling up task-sharing and expanded roles for non-specialists through programs such as the World Health Organization's Mental Health Gap Action Programme, community-based interventions like Zimbabwe's Friendship Bench, and integration of mental health into primary care with dedicated counsellors, structured referral pathways, and digital innovations promising improved access and personalization. Sustained progress requires intersectoral collaboration across health, education, labor, and social sectors; embedding mental health into national health information systems; and investing in culturally adapted promotion and prevention interventions throughout the life course. Strengthening political commitment, global-local leadership, financing frameworks, and workforce capacity, particularly through continuous professional development and lived-experience participation, will accelerate progress toward the SDGs, underscoring the imperative for equitable financing and sustained political will globally.}, }

We elucidate how customized delivery platforms, particularly lipid nanoparticles, augment the stability and immunogenicity of parasite-derived mRNA cargo by safeguarding it from degradation and promoting uptake by antigen-presenting cells. Our findings suggest that mRNA technology provides a particularly adaptable strategy to targeting complicated parasite life cycles and efficiently modulating host immune responses. However, important challenges, such as cold-chain logistics, scalability, clinical trial design for diverse populations, and managing public opinion, must be solved beforehand. Future initiatives must priorities the creation of thermostable formulations and effective community participation strategies.

This scoping review aimed to explore how the COVID-19 pandemic affected vascular access practices and catheter-related complications, with the objective of mapping innovations, identifying emerging trends, and summarizing preventive and therapeutic strategies. The review followed PRISMA-ScR guidelines and was registered in PROSPERO (CRD420251027530). A systematic search was conducted in PubMed[®], EMBASE[®], EBSCO-CINAHL[®], and CENTRAL for English-language studies published between January 2020 and May 2025 addressing catheter-related complications in COVID-19 patients, including catheter-related bloodstream infections (CRBSI), central line-associated bloodstream infections (CLABSI), catheter-related thrombosis (CRT), and accidental catheter removal. Among 521 screened articles, 58 met the inclusion criteria. Most studies reported higher rates of CRBSI, CLABSI, CRT, and accidental removal in COVID-19 patients, especially in critical care settings. Arterial catheters were also associated with elevated risks of thrombosis and infection during the pandemic. Mid-thigh femoral access sites emerged as practical alternatives to reduce central line use and healthcare personnel exposure. Technological advances, including power-injectable catheters, ultrasound-guided insertion, intracavitary ECG for tip confirmation, and securement tools such as cyanoacrylate glue and subcutaneous anchor systems, improved safety and reduced mechanical and infectious complications. Chlorhexidine-based antisepsis, antimicrobial-impregnated devices, and disinfectant caps effectively decreased CRBSI and CLABSI rates. In older, comorbid patients-now representing the majority of COVID-19 hospitalizations-nutritional and anticoagulant therapy must be carefully balanced to minimize bleeding and thrombotic risks. In conclusion, the pandemic catalyzed significant innovation and adaptation in vascular access practices. Integrating portable technologies, infection prevention strategies, and alternative access routes has enhanced patient care and established new standards for managing intravenous therapy in high-risk, resource-constrained settings.}, }

Data were obtained through these regulatory bodies and direct researcher communication rather than through systematic searches.<br><br>SELECTION CRITERIA: Data sources required secondary population-based data to identify pregnancies with COVID-19, along with hospitalization, diagnostic and medication codes. Eligibility for the meta-analysis was determined through protocol evaluation and researcher consultations.<br><br>DATA COLLECTION AND ANALYSIS: PRISMA-IPD and Cochrane guidelines for prospective meta-analysis were followed. Protocols and definitions were standardized across sources, and a common R script was developed. Initially, crude and adjusted relative risks (aRR) with 95% confidence intervals (CI) were calculated to assess adverse outcomes in pregnant women with and without COVID-19 in each data source. Estimates were stratified by trimester at infection and hospitalization status. Subsequently, data were pooled using a random-effects meta-analysis.<br><br>MAIN RESULTS: Data from 10 sources across seven countries contributed to the meta-analysis, including 86&#x2009;210 pregnant women diagnosed with COVID-19, of whom 4.4% were hospitalized. Non-hospitalized pregnant women with COVID-19 had no increased risks of adverse outcomes compared to pregnant women without COVID-19. However, hospitalized women with COVID-19 in each trimester had higher risks of cesarean section, preterm birth, and LBW compared to pregnant women without COVID-19.

TLRs contribute to these responses by increasing the levels of cytokines, interleukins, and other inflammatory mediators through multiple pathways. Located both intracellularly and on the surface of various cells and tissues, including vascular smooth muscles (VSMs) and myocardium cells, TLRs play distinct roles in innate immune activation, such as recognizing pathogen-associated molecular patterns (PAMPs) and activating downstream signaling pathways. In the context of COVID-19, TLRs are critically involved in the pathophysiology by mediating excessive inflammatory responses that exacerbate disease severity, influencing both the acute phase and long-term outcomes. It has been observed that inflammatory diseases such as atherosclerosis, viral myocarditis, and other comorbidities associated with the spread of COVID-19 have increased, although the exact mechanisms remain not fully understood. Nonetheless, there is evidence of TLR-mediated increased pro-inflammatory signaling by different mechanisms in these diseases. This review explains the role of TLRs in various inflammatory diseases related to COVID-19, including viral myocarditis, acute lung infections, and atherosclerosis. Furthermore, the review discusses various herbal drugs, such as Platycodon grandiflorum, Acanthopanax senticosus, Scutellaria baicalensis Georgi, and Engelhardia roxburghiana, and their mechanisms of action on TLRs, including NF-κB, MyD88-dependent, MyD88-independent pathways, and Plasmacytoid DCs. Enhanced clarity on TLRs' specific contributions to COVID-19 pathophysiology and stronger evidence supporting herbal interventions targeting TLRs could improve the impact and applicability of these findings in clinical settings.}, }

By subverting autophagy, SARS-CoV-2 proteins such as ORF3a, ORF7a, and NSP6 inhibit autophagosome-lysosome (APG-L) fusion, generating "incomplete autophagy" that permits viral persistence and drives hyperinflammation. Transcription factor EB (TFEB), a master regulator of lysosomal biogenesis and autophagy, has emerged as a central player in the host response to coronavirus infection. TFEB orchestrates the expression of genes required for lysosomal function and autophagic flux while also shaping immune processes, including cytokine production, interferon-stimulated gene expression, and inflammasome clearance. This mini review synthesizes current knowledge on the TFEB-ALP axis in COVID-19 pathogenesis, highlighting its influence on acute immunopathology and its potential contribution to post-acute sequelae (Long COVID). Restoring TFEB activity and autophagic flux may counteract SARS-CoV-2 evasion strategies and restrain aberrant inflammatory responses. Harnessing the TFEB-autophagy pathway as a host-directed therapeutic strategy could help rebalance immune homeostasis, limit tissue damage during acute infection, and mitigate persistent inflammatory sequelae in Long COVID.}, }

Recent evidence suggests an increased prevalence in normal-weight and obese children. Under-recognition of patients with normal or high BMI can lead to delayed diagnosis and serious complications. The present study aimed to determine the BMI status of children with CeD at diagnosis and before gluten-free diet (GFD). A systematic review and meta-analysis was conducted following the PRISMA and MOOSE guidelines and after PROSPERO registration (CRD42023390243). The information sources, including PubMed, Scopus, and Web of Science, were systematically searched through 30 September 2025 to identify relevant articles. The study's eligibility criteria included observational studies, such as retrospective, cross-sectional, and prospective designs, with participants whose CeD diagnosis was confirmed by a gastroenterologist and who reported BMI data at the time of diagnosis. Heterogeneity among studies was assessed using the I[2] statistic. Funnel plots and Egger's test were also used to examine publication bias. The risk of bias of studies was assessed using the Newcastle-Ottawa (NOS) scale. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) framework was used to determine the certainty of the evidence. Overall, 32 studies including 14,169 children with CeD were investigated. The pooled prevalence of underweight and overweight/obesity at diagnosis was 15.3% (10.8-20.4%) and 10.5% (5.7-16.4%), respectively. Subgroup analysis by WHO region revealed a marked heterogeneity (I[2] > 90%), with the highest prevalence of underweight observed in the Eastern Mediterranean Region (EMRO) (31.9%). On the other hand, the highest prevalence of overweight/obesity was observed in the European Region (EURO) (12.0%) and the Western Pacific Region (WPRO) (21.4%). A key finding was a significant difference across World Bank income groups; underweight prevalence was nearly four times higher in low- and middle-income countries (LMICs), 35.48 (24.29, 47.51), compared with high-income countries, 9.58 (6.88, 12.63). The certainty of the evidence for all pooled prevalence estimates was rated as very low due to serious inconsistency and imprecision.<br><br>CONCLUSIONS: &#xa0;The prevalence of normal weight and overweight/obesity in children with celiac disease at diagnosis was higher than that of underweight, mainly in high-income countries. This finding challenges the traditional belief about the CeD and emphasizes its diagnosis in children with suspicious symptoms, regardless of their BMI status. This approach will lead to earlier diagnosis, improving clinical outcomes and quality of life for patients in the long term.<br><br>WHAT IS KNOWN: &#x2022; The clinical presentation of celiac disease is evolving, and its association with underweight is inconsistent. &#x2022; The structural effects of COVID-19 on the developing brain remain poorly understood due to limited pediatric imaging studies.<br><br>WHAT IS NEW: &#x2022; This is the first meta-analysis focused exclusively on children, revealing that the majority (70.2%) present with a normal BMI at diagnosis. &#x2022; The clinical inconsistency in BMI presentation is strongly linked to income levels; underweight prevalence is nearly four times higher in LMICs (35.5%) than in high-income countries (9.6%).}, }

However, as of 2021, it remained one of the three Western European countries with the highest rates of new HIV infections and AIDS cases. Initially shaped by HIV exceptionalism, Portugal began transitioning to a universal testing strategy in 2011. This study provides a historical and policy review of the evolution of HIV testing in Portugal, focusing on alignment with international guidelines and national implementation outcomes.<br><br>METHODS: We conducted a narrative policy review covering the period from 1998 to 2024. Our analysis drew on scientific literature, national health plans, surveillance reports, and international guidelines. Documents were selected through structured searches in multiple academic databases and government repositories using relevant Portuguese and English search terms. Thematically coded findings were mapped chronologically and assessed against evolving WHO and CDC recommendations.<br><br>RESULTS: Portugal gradually moved from a targeted testing approach to a more comprehensive, universal strategy. Key policy shifts occurred in 2011 and 2017, accompanied by an expansion of testing modalities, including self-testing and community-based testing. Despite these developments, implementation has been uneven. The lack of standardized protocols, limited integration into primary healthcare, and regional disparities tied to a contract-based health system have contributed to inconsistent service delivery. Additionally, testing uptake among older adults, migrants, and other key populations remains suboptimal. The COVID-19 pandemic temporarily disrupted testing services but also accelerated the use of self-testing strategies.<br><br>DISCUSSION: Portugal's experience illustrates the challenges of operationalizing universal HIV testing within a hybrid public-private healthcare system. Although policies increasingly reflect international best practices, structural barriers continue to hinder equitable implementation.<br><br>CONCLUSION: To close existing testing gaps, Portugal must strengthen implementation by standardizing procedures, improve disaggregated data collection in monitoring systems, and ensure greater integration of HIV testing in primary healthcare.

Five databases (PubMed, IEEE, Springer, ScienceDirect, ACM) were searched for peer-reviewed articles published between January 2019 and July 2025. Eligible studies applied predictive algorithms - excluding those focused on COVID-19 - to forecast ED visits. Extracted data included modeling approaches, feature types, evaluation metrics, and validation methods.<br><br>RESULTS: Eleven studies met the inclusion criteria. Classical models such as ARIMA and SARIMA remain in use, but ML (e.g., XGBoost, Random Forest) and DL (e.g., LSTM, CNN) showed higher predictive accuracy, especially with high-dimensional, nonlinear data. Incorporating external variables-such as weather (temperature, humidity, wind), air quality, and calendar events-consistently improved performance. Common metrics included Mean Absolute Error (MAE), Root Mean Squared Error (RMSE), and Mean Absolute Percentage Error (MAPE), with MAPE ranging from 3&#xa0;% to 18&#xa0;%. Few studies performed external validation, and only a minority employed explainable AI methods (e.g., SHAP) to address interpretability.<br><br>CONCLUSIONS: AI-based models offer strong potential for ED demand forecasting, particularly when integrating environmental and temporal features. However, limited external validation and lack of interpretability remain significant barriers to clinical adoption.

As these programs expand, the management of the extensive data they generate becomes increasingly complex, highlighting the need for structured digital solutions. This narrative review article presents a pragmatic framework aimed at clarifying big data analytics tailored to the needs and practices of healthcare professionals and administrators, focusing on effective integration into routine screening workflows. To achieve effective data utilization, the process begins with systematic archiving, which involves cloud-based storage solutions capable of securely maintaining various data formats in compliance with regulatory standards, thus ensuring long-term accessibility and continuity. Subsequent real-time processing of screening data facilitates rapid decision-making and patient management by providing immediate validation and analysis, essential for maintaining the responsiveness of screening services. Transformation processes play a critical role in converting diverse data inputs into standardized, consistent formats, enabling seamless communication and exchange among multiple healthcare systems. Integration further builds upon this standardization, merging data from different healthcare providers and diagnostic centers into centralized analytical platforms. This unified approach enables comprehensive patient monitoring and supports predictive modeling for early identification of at-risk individuals. Advanced analytics, particularly process mining and predictive techniques, reveal inefficiencies within screening workflows, highlighting areas needing improvement. These methods help healthcare managers to streamline operations, optimize resources, and enhance overall program performance. Real-time visualization tools provide administrators with continuous, practical insights into operational dynamics, despite existing challenges related to data governance and system interoperability. This article illustrates these concepts through concrete examples from the colorectal cancer screening program in Northern Portugal and the response to the COVID-19 pandemic. The colorectal cancer screening scenario demonstrates how structured data management significantly boosts operational efficiency and healthcare accessibility. Meanwhile, the COVID-19 experience highlights the importance of having flexible digital infrastructures capable of quickly adapting to unexpected crises. Finally, ongoing investments in digital infrastructure, professional training, and comprehensive data governance are crucial for sustaining these improvements. This review provides clear, actionable knowledge to support healthcare professionals in adopting big data analytics effectively within preventive healthcare programs.}, }

The aim of this review is to discuss the current epidemiology of MERS-COV both in humans and animals, during and post the COVID-19 pandemic. We have found that MERS-COV is still evolving in camels with new lineages being detected in Saudi Arabia. Although the number of human cases has decreased, there is a gradual resurgence in the number of cases. Furthermore, many cases are being reported without exposure to camels and/or raw products, nor contact with known human cases. This necessitates global efforts in the surveillance of asymptomatic carriers in the community, role of unknown animal reservoirs in the virus spread if any, as well as extensive genomic surveillance of the virus. This is in order to unveil and assess the genetic changes that the virus is undergoing and their according effect on the viral fitness, tropism, and virulence. These efforts are crucial for potential future pandemic preparedness, understanding the modes of transmission, as well as drug and vaccine development for MERS-COV.}, }

To meet this need, the European Medicines Agency and other health authorities expected that, in addition to routine signal detection, COVID-19 vaccine manufacturers should leverage observed-to-expected (O/E) analyses unconventionally as a quantitative method for signal detection of adverse events of special interest (AESIs). The objective of O/E analyses in vaccine signal detection was to determine if AESIs were occurring at a higher-than-expected rate in the vaccinated population in comparison with an unexposed population. The use of O/E was intended to mitigate the challenge of analyzing large volumes of individual case safety reports (ICSRs) received over a very short period following mass vaccination campaigns. The "Beyond COVID-19 Monitoring Excellence" (BeCOME) initiative, a non-competitive voluntary initiative launched in 2022 by COVID-19 vaccine Marketing Authorization Holders (MAHs) and key stakeholders, was established to align systems, enhance processes, and foster innovation in post-marketing vaccine monitoring, building on lessons from the pandemic. A dedicated working group was created to review and share MAHs' experience on O/E analyses used as an additional tool for signal detection during the COVID-19 pandemic. This review presents the industry perspective on using O/E analyses for COVID-19 vaccine signal detection, including challenges and limitations encountered, and proposes best practices for future improvement. Despite the priority and resources devoted to O/E analyses, no de novo signals resulting in the identification of safety concerns were detected using this methodology during the COVID-19 pandemic. O/E analyses are most useful when source data are accurate and there is a high level of confidence in the assumptions and parameters used. In the context of the COVID-19 pandemic, confidence in certain assumptions and parameters was low, limiting the value of O/E analyses in signal detection. Nevertheless, O/E analyses applied for signal refinement, as traditionally used, proved to be useful. Industry experiences support maintaining O/E analyses as a tool for signal refinement and standardizing methodological approaches as much as possible to enhance its future application and comparability across stakeholders.}, }

Pathogens such as Helicobacter pylori Staphylococcus aureus, Escherichia coli, SARS-CoV-2, and hepatitis viruses, alter host metabolic signaling through inflammatory, mitochondrial, and hormonal pathways, reshaping glucose and lipid homeostasis. In turn, diabetic immune impairment amplifies susceptibility to pneumonia, urinary tract infections, and chronic wound infections, reinforcing a pathogenic feedback loop. Emerging therapeutic strategies including nanotechnology enabled, therapeutics, gene, and stem cell based interventions and next-generation incretin agonists- including tirzepatide and CagriSem offer promising avenues to restore both metabolic balance and immune resilience. Additionally, foundational strategies such as lifestyle modifications, medical nutrition therapy, and vaccination remain essential components of disease control. Understanding infections as dynamic modulators of metabolic homeostasis reframes diabetes not merely as an endocrine disorder, but as a systemic immunometabolic disease.

New treatments may be developed through a better understanding of the molecular processes underlying viral replication. The low-density lipoprotein receptor (LDLR) serves as a critical entry portal for a diverse range of infectious agents, facilitating the initiation and perpetuation of their infection cycles. Furthermore, numerous viruses, such as the dengue virus and the hepatitis C virus (HCV), depend on host cholesterol (CHO) for replication and spread. Consequently, targeting the LDLR with pharmacological agents presents a promising therapeutic strategy for a broad spectrum of viral infections, including those caused by human immunodeficiency virus (HIV), HCV, and severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2). In addition, human metapneumovirus (HMPV) is a leading cause of respiratory infections in young children, underscoring the need for effective treatments. This research investigates the role of the LDLR in HMPV and other emerging viruses. A key finding is that HMPV infection depends on LDLR-mediated pathways, as evidenced by the rapid recovery observed after exogenous CHO administration.

Far from being inert genetic fossils, HERVs have co-evolved with their hosts, acquiring regulatory and functional roles that influence development, immunity and disease. In this comprehensive review, we examine the origin, evolutionary dynamics and structural diversity of HERVs, emphasising their integration, genomic organisation and mosaic recombination patterns. We further highlight how epigenetic modifications, intracellular factors such as transcriptional regulators, hormones and cytokines, and environmental influences regulate HERV expression. By synthesising current evidence linking HERV activity to immune modulation, tumourigenesis, autoimmunity and neurodegenerative processes, we provide an integrated perspective on their dual role as drivers of pathology and contributors to normal physiology. Our analysis underscores that HERVs are not only markers of past infections but also active genomic elements with potential clinical implications, from biomarker discovery to novel therapeutic targets, making their systematic investigation timely and highly relevant.}, }

We set out to try to simplify this process by reviewing the epidemiology of a range of pathogens with pandemic potential and seeing whether they fall into groups with shared epidemiological traits.<br><br>METHODS: We reviewed the epidemiological characteristics of 19 different pathogens with pandemic potential (those on the WHO priority list of pathogens, different strains of influenza and Mpox). We extracted data on key parameters (reproduction number serial interval, proportion of presymptomatic transmission, case fatality risk and transmission route) and applied an unsupervised learning algorithm. This combined Monte Carlo sampling with ensemble clustering to classify pathogens into distinct epidemiological archetypes based on their shared characteristics.<br><br>RESULTS: From 154 articles we extracted 302 epidemiological parameter estimates. The clustering algorithms categorise these pathogens into six archetypes (1) highly transmissible Coronaviruses, (2) moderately transmissible Coronaviruses, (3) high-severity contact and zoonotic pathogens, (4) Influenza viruses (5) MERS-CoV-like and (6) MPV-like.<br><br>CONCLUSION: Unsupervised learning on epidemiological data can be used to define distinct pathogen archetypes.

Over the past decade, advances in polymerase chain reaction (PCR), next-generation sequencing (NGS), digital PCR, isothermal amplification, and CRISPR-based assays have enhanced pathogen identification, antimicrobial resistance profiling, and outbreak investigation. These technologies have been instrumental in detecting and monitoring emerging and re-emerging viral pathogens such as SARS-CoV-2, Nipah, Zika, H5N1 avian influenza, Mpox, Ebola, Marburg, and MERS-CoV. Molecular diagnostics also play a critical role in antimicrobial resistance surveillance and hospital infection control by enabling high-resolution tracking of resistance genes and pathogen transmission dynamics. Despite these achievements, challenges remain regarding implementation costs, technical expertise, infrastructure, and the need for global standardization. Future directions focus on developing cost-effective, point-of-care molecular platforms, integrating artificial intelligence and bioinformatics for enhanced interpretation, and applying these technologies within One Health and environmental surveillance frameworks. These innovations will be pivotal for early outbreak detection, real-time data-driven decision-making, and equitable access to advanced diagnostics worldwide.

Wastewater surveillance can detect pathogens that circulate throughout society, including asymptomatic infections, thereby allowing early outbreak warnings. However, several error factors must be considered when applying wastewater surveillance for COVID-19. This study examines the key error factors in COVID-19 wastewater surveillance and discusses their future applicability in Japan.Methods A literature search was conducted using PubMed and Ichushi-Web to review the studies on wastewater surveillance for COVID-19. The search included combinations of the keywords "wastewater," "sewage," "COVID-19," "SARS-CoV-2," "fecal/urine," and "surveillance/survey/detection." A narrative review was conducted based on the search results.Results A total of 2,108 articles were identified in PubMed, of which 19 were included in this review. In addition, six academic articles were retrieved from Google Scholar, and two government reports and guidelines were included in this review. The sampling methods and environmental factors such as wastewater temperature, transit time, and composition can be potential sources of error in wastewater surveillance. Furthermore, the standardization of these factors is difficult. The prevalence of COVID-19, population size, and population mobility in the target area also influence data interpretation. Additionally, because wastewater surveillance often lacks detailed patient background information such as age, sex, and exact locations of affected individuals, data interpretation can be more challenging than clinical testing-based surveillance, thus potentially limiting its applicability. However, compared to large-scale clinical screening, wastewater surveillance is significantly more cost-effective, rapid, and suitable for continuous monitoring. With regard to statistical analysis, sample normalization is crucial for accurate comparisons across samples, regions, and time periods. A low signal-to-noise ratio during COVID-19 wastewater surveillance requires significant smoothing procedures to extract meaningful signals.Conclusion Wastewater surveillance for COVID-19 is subject to errors from several sources. Nevertheless, it offers advantages over clinical surveillance that include lower expected costs and capacity for continuous monitoring across broad geographic areas. In conclusion, it is essential to understand the advantages and limitations of both clinical and wastewater surveillance and appropriately integrate both approaches for optimal utilization.}, }

PubMed, Embase and Web of Science were searched systematically according to eligibility criteria to March 2024, with an update in May 2025. Random-effects meta-analyses using the 'dmetar' package (V.0.0.9000) in R V.4.3.1 were performed for studies comparing individuals with and without brain fog. Bias was assessed using the National Institutes of Health Study Quality Assessment Tools.<br><br>FINDINGS: Of 3077 records screened, 65 studies met inclusion criteria: 40 investigated brain fog in long covid and 25 in chemotherapy populations. Considerable variation in assessment tools was observed. Montreal Cognitive Assessment was the most common cognitive test in long covid studies; Functional Assessment of Cancer Therapy-Cognitive Function was most used in chemotherapy studies. Nine long covid studies were eligible for meta-analysis. Compared with controls, individuals with brain fog had significantly lower cognitive performance (Hedge's g=-0.63, 95%&#x2009;CI -1.15 to -0.12), higher fatigue (Hedge's g=2.64, 95%&#x2009;CI 0.41 to 4.86) and more depressive symptoms (Hedge's g=1.48, 95%&#x2009;CI 0.40 to 2.55). Heterogeneity was high (I[2]>70%). No chemotherapy studies were appropriate for meta-analysis, preventing direct comparison of brain fog features between long covid and chemotherapy groups.<br><br>CONCLUSIONS: Brain fog in long covid and chemotherapy populations is associated with cognitive complaints, fatigue and mood disturbance, though assessment methods differ widely. To improve comparability and clinical understanding, we propose adoption of consistent tools and definitions in future studies.

The most prescribed drugs were hydroxychloroquine (64.3%, i.e. 41.9% of all patients), corticosteroids (31.0%, i.e. 21.0%) and lopinavir/ritonavir (30.8%, i.e. 12.0%). Corticosteroids was used worldwide with similar rates in Asia, Europe and North America. Hydroxychloroquine dominated prescriptions in Africa, Europe and North America. Asia exhibited unique features: less frequent hydroxychloroquine use, higher oseltamivir use and exclusive use of umifenovir. In Europe, repurposed drugs prescription was the highest in Spain and Italy.

COVID-19 causes pulmonary and extra-pulmonary manifestations. One of the most common extra-pulmonary manifestations is gastrointestinal (GI) manifestation. Enteric COVID-19 triggers changes in the diversity of gut microbiota (dysbiosis). Dysbiosis of gut flora increases gut permeability, resulting in secondary bacterial infections, systemic inflammation, and injury of the peripheral organs. Dysbiosis may affect the immune system and pulmonary response to the SARS-CoV-2 invasion, suggesting a link between the lungs and gut through the gut-lung axis. Intestinal inflammation caused by SARS-CoV-2 infection induces leaky gut with subsequent transmission of toxins and antigens to the systemic circulation, causing further worsening of the septic condition in COVID-19 patients. Therefore, the anti-inflammatory agents' interruption of the gut-lung axis may reduce respiratory complications due to intestinal inflammation in COVID-19. Rifaximin (RXM) is a semi-synthetic antibacterial drug derived from natural rifamycin that acts locally within GI by inhibiting bacterial RNA polymerase and reducing the bacterial population and associated intestinal inflammation. RXM inhibits bacterial adherence to the intestinal epithelial lining and translocation across this GI lining. RXM has anti-inflammatory effects by inhibiting the release of pro-inflammatory cytokines and modulating the gut pregnane X receptor (PXR). RXM acts as a prebiotic in maintaining the growth of gut microbiota and may prevent the development of COVID-19-induced dysbiosis. Therefore, RXM could be effective in managing COVID-19 and associated inflammatory complications. Therefore, this review aims to discuss the potential role of RXM in managing COVID-19.}, }

After analyzing the studies, the most common short-term consequences, such as obesity, sleep disorders, and dry eye syndrome, were identified. Many studies have highlighted the impact of particularly long periods of screen time, more than 3-4 hours. The health consequences that manifest themselves later include hypertension, cardiovascular disease, and myopia. This impact also extends to mental health, where there is a clear correlation between long screen time and a higher incidence of anxiety, depression, and behavioral problems. Evidence indicates an increase in children's screen time since the COVID-19 pandemic. Due to the continuing high level of screen time, associated not only with entertainment but also with the transfer of certain activities to an online format, despite the end of the pandemic, public health interventions and educational strategies are urgently needed to mitigate these negative effects and promote a healthy lifestyle among children, which will translate into the health of the entire population in the future.}, }

Breast cancer is a heterogeneous disease and many of its subtypes are immunologically cold tumours, which has limited the progress of immunotherapy in this field. Recent studies have highlighted the potential of mRNA vaccines to reshape the tumour immune microenvironment in breast cancer. These vaccines can enhance antigen presentation, activate T cell responses, and convert immunologically cold tumours into immune-active ones. This review provides a comprehensive overview of recent advances in mRNA vaccine development for breast cancer with a focus on antigen selection, mRNA design, and delivery strategies. It also examines findings from both preclinical and clinical studies as well as recent progress in industrial development.

Genetic predisposition, environmental factors such as infections and stress, disruptions in the gut microbiome, excessive iodine intake, and epigenetic changes have all been implicated in the development of GD. The recent pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) posed a serious global health crisis. The emergence of COVID-19 vaccines has been pivotal in combating the viral infection and its spread. However, reports of rare adverse events, including the development of autoimmune disorders such as GD following vaccination, have raised concerns. Autoimmune factors play a critical role in the pathogenesis of GD, particularly through the production of autoantibodies targeting the thyroid gland. In this review, reported cases are critically analyzed to elucidate commonalities and potential triggers for the development of this autoimmune disorder, highlighting the vital role of autoimmune mechanisms in inducing GD. We also discuss the molecular mechanisms underlying vaccine-induced autoimmunity, including antigen presentation, bystander activation, molecular mimicry, and the induction of inflammatory factors following vaccination. Understanding these mechanisms in COVID-19 vaccine-induced GD could enhance patient care and guide vaccination policies.}, }

SIRT1 influences the expression of angiotensin-converting enzyme 2 (ACE2), the primary receptor for SARS-CoV-2, thereby potentially mitigating viral entry and replication. Natural activators of SIRT1, such as resveratrol, have been shown to enhance its activity, offering promising avenues for therapeutic interventions aimed at bolstering the immune response during COVID-19.

Observational studies were included if they employed cross-sectional or longitudinal designs and reported the prevalence of SI before and after the pandemic across global regions.<br><br>RESULTS: The analysis included 354 cross-sectional studies (N = 8,247,875) and 27 longitudinal studies. In cross-sectional studies, the pooled prevalence of SI was 13.20% [95% CI 12.06%-14.42%]. Pre-pandemic prevalence was 12.52% [95% CI 8.46%-18.14%], and post-pandemic prevalence was 13.24% [95% CI 12.07%-14.50%], with no significant difference. Meta-regression analysis identified three moderators. Specifically, larger sample sizes (n) were associated with lower prevalence (&#x3b2; = -0.232, P < 0.0001); higher study quality predicted lower prevalence (&#x3b2; = -0.278, P < 0.001); and studies on adults reported significantly lower prevalence than adolescents (&#x3b2; = -0.366, P < 0.05). Conversely, time progression during the pandemic, development level, geographical area, gender and measurement method did not show significant independent effects. Interaction analyses also found no significant moderating effect of economic development level or geographical area on the temporal trend of SI prevalence. Longitudinal analysis found no significant increase in prevalence from the pre-pandemic to the post-pandemic period (P = 0.101). However, a small but significant increase occurred between early and late stages within the pandemic (&#x3b2; = 0.265, P = 0.021). Subgroup analyses showed no significant moderation of these temporal changes.<br><br>CONCLUSIONS: The COVID-19 pandemic's impact on SI was dynamic. While no significant prevalence change was found between pre- and post-pandemic periods, a significant increase occurred as the crisis progressed. This deteriorating trend was more pronounced in adolescents, identifying them as a key vulnerable group. Methodologically, findings were moderated by the measurement instrument, study quality and sample size, with evidence suggesting potential small-study effects. These findings underscore the need for robust mental health surveillance and targeted interventions for at-risk populations during prolonged public health crises.The protocol was registered on PROSPERO (CRD42024603151).}, }

Following duplicate removal and eligibility screening, 14 peer-reviewed studies published between 2020 and 2025 were included. An integrative narrative approach was used to synthesize evidence on social media behavior, misinformation dynamics, and digital health campaigns. The analysis was grounded in infodemiological and infoveillance frameworks as established by Eysenbach, incorporating insights from psychology, media studies, and public health.<br><br>RESULTS: Memes function as emotionally salient and visually potent carriers of health-related narratives. While they can simplify complex messages and foster adaptive humor during crises, they are also susceptible to distortion, particularly in echo chambers and conspiracy communities. Findings reveal that misinformation-laden memes often leverage humor and disgust to bypass critical thinking, and their viral potential is linked to emotional intensity. However, memes have also been successfully integrated into prebunking strategies, increasing engagement and reducing susceptibility to false claims when culturally tailored. The review identifies key mechanisms that enhance or hinder the infodemiological value of memes, including political orientation, digital literacy, and narrative framing.<br><br>CONCLUSIONS: Memes are a double-edged sword in the context of infodemics. Their integration into infodemic surveillance and digital health campaigns requires a nuanced understanding of their emotional, cultural, and epistemic effects. Public health institutions should incorporate meme analysis into real-time infoveillance systems, apply evidence-based meme formats in prebunking efforts, and foster digital literacy that enables critical meme consumption.

We include 29 studies documenting the use of a broad range of advanced and straightforward machine-learning techniques to study infectious and chronic diseases such as COVID-19 (4 studies, 13.8%), malaria (5, 17.2%), and cervical cancer (2, 6.9%). Countries with high internet and mobile phone penetration have higher representation. Based on identified gaps, we make research and policy recommendations to enhance the contribution of these tools in advancing health in Africa. These include investing in studies on chronic diseases and implementing frameworks to address geographic inequity.}, }

Within the broader resurgence of IMD observed since relaxation of quarantine measures introduced to mitigate the impact of the COVID-19 pandemic, there has been a notable increase in reporting of such atypical cases. The aim of this review is to summarize epidemiological, diagnostic, and treatment aspects of non-meningeal forms of IMD in older patients, with a focus on meningococcal pneumonia. By convention, laboratory confirmation requires N. meningitidis detection by culture, polymerase chain reaction (PCR), or antigen detection. In most cases, presentation of meningococcal pneumonia is similar to that of other forms of community-acquired pneumonia, and cerebrospinal fluid sampling may be non-informative. This places a premium on early blood culture for N. meningitidis, allied with testing of respiratory samples (e.g., broncho-alveolar washes). Many cases are linked to isolates of serogroups Y and W. When confirmed, treatment with third-generation cephalosporins is generally preferred. Chemoprophylaxis and vaccination of close contacts is essential for controlling onward meningococcal disease transmission and prevention of further cases.}, }

Older adults, often burdened by multimorbidity, frailty, and immunosenescence, are highly vulnerable to vaccine-preventable diseases such as influenza, pneumococcal pneumonia, COVID-19, respiratory syncytial virus (RSV), pertussis, and herpes zoster (HZ). Despite the availability of effective vaccines, immunization coverage in LTCFs remains inadequate, hindered by fragmented national policies, insufficient mandates, and systemic neglect of adult vaccination. In many settings, vaccination uptake is not even systematically monitored, leaving policymakers and clinicians without reliable data to identify gaps or measure progress. The COVID-19 pandemic underscored these vulnerabilities, temporarily spurring emergency vaccination efforts but failing to establish sustainable, life-course immunization frameworks. This consensus document, developed by the European Interdisciplinary Council on Ageing (EICA) following the San Servolo (Venice, Italy) 2025 meeting, synthesizes evidence on intrinsic and environmental infection risk factors in LTCFs, the health and economic burden of infections, and the persistent gaps in vaccine uptake among both residents and staff. We highlight the cost-effectiveness of preventive interventions, the critical role of non-pharmacological infection control measures, and the need to address antimicrobial resistance through integrated vaccination strategies. The Council emphasizes that routine adult vaccination must become a structural element of care planning for ageing populations, supported by digital registries, systematic assessments at LTC admission, co-administration strategies, and robust staff engagement. Stronger global and national policy leadership is urgently needed to align LTCF immunization with life-course approaches and primary healthcare integration. Protecting frail older adults from infectious diseases is not only a clinical necessity but also a societal obligation-central to safeguarding dignity, resilience, and healthy ageing in Europe and beyond.}, }

However, little is known about the needs of family members when collaborating specifically with support staff caring for their relative. This scoping review provides an overview of existing literature to inform future research.<br><br>METHOD: The review was conducted in accordance with the PRISMA for Scoping Review statement. Seven databases were systematically searched in April 2022 (with a final update in May 2025). Studies that were published in English in peer-reviewed journals and examined the needs and experiences of family members collaborating with support staff in residential care settings were considered for inclusion. The Mixed Methods Appraisal Tool was used to assess risk of bias and a thematic synthesis was conducted to analyse the data.<br><br>RESULTS: Ten articles met the inclusion criteria. Four studies focused on family members' experiences following a relative's transition from institutional or hospital settings, one study on sibling-staff collaboration, one on the roles of adult siblings, one exploring family experiences during the COVID-19 pandemic, one on parental perceptions of communication, one on family experiences postabuse inquiry and one focused on collaboration within hospital settings. The studies involved relatives with severe (n&#x2009;=&#x2009;1), mild, severe and profound (n&#x2009;=&#x2009;1), severe to profound (n&#x2009;=&#x2009;1) or profound intellectual disabilities (n&#x2009;=&#x2009;3). Four did not mention the level of intellectual disability. The synthesis yielded four analytical themes: (1) complexities in building personal relationships amidst changing contexts (n&#x2009;=&#x2009;8), (2) navigating how to address unmet needs and the vulnerability it exposes (n&#x2009;=&#x2009;3), (3) a desire for partnership and recognition (n&#x2009;=&#x2009;10) and (4) a desire for staff to uphold their relative's quality of life (n&#x2009;=&#x2009;10).<br><br>DISCUSSION: This review highlights key areas for future research, including how family characteristics, disability severity and living arrangement can influence needs and experiences when collaborating with support staff. Additionally, further insight is needed on what impacts the dynamic nature of family-staff relationships. Lastly, understanding the views and experiences of support staff regarding family involvement is important, as it can aid the development of collaboration that is sensitive to their specific needs.}, }

The primary outcome of interest was the change in fracture incidence, analysed using risk ratios (RR) with 95% confidence intervals (CI) in Review Manager 5.4. Subgroup analyses were performed by sex, geographic region, and fracture type.<br><br>RESULTS: Nine studies meeting the inclusion criteria were analysed. Overall, "all types" of osteoporotic fractures showed a significant decrease during the pandemic (RR = 0.85, 95% CI 0.80-0.91, p&#x2009;<&#x2009;0.0001). Specifically, forearm fractures decreased significantly (RR = 0.87, 95% CI 0.79-0.96, p&#x2009;=&#x2009;0.002).

The prevalence of insomnia generally increases with age, often persisting into adulthood if unaddressed. Insomnia is exceedingly common among those with developmental disabilities and is frequently comorbid with a great range of psychiatric diagnoses. The COVID-19 pandemic has only increased the prevalence of insomnia among children and adolescents. Health care providers are routinely called upon to treat insomnia in the pediatric population. Psychoeducation and behavioral interventions, especially cognitive behavioral therapy for insomnia (CBT-I), remain the first line treatments, given empirical evidence for their efficacy and success in relapse prevention. However, medications are frequently employed in clinical practice, despite the fact that no medications are approved by the Food and Drug Administration (FDA) for the treatment of pediatric insomnia. This review was designed to educate and support practitioners who are treating children and adolescents who struggle with insomnia. A thorough narrative review was completed to identify all published medication studies of pediatric insomnia; the identified studies are described and then graded into four categories according to the strength of the evidence supporting their use, side effect profiles, co-morbidities, and overall risk vs. benefit of each pharmacological treatment. This review will help practitioners in making clinical decisions for their pediatric patients who suffer with insomnia.}, }

Meanwhile, published research continues to offer insight into the efficacy of probiotics as antiviral agents. Various clinical findings reveal those specific probiotic strains aid in the prevention of viral and bacterial infections. Probiotics have been used to prevent and treat common viral infections such as rotavirus, coronavirus, hepatitis, human papillomavirus, human immunodeficiency virus, and herpes simplex viruses etc. The studies compiled in this review demonstrate the value of probiotics in the treatment and prevention of several viral infections using in vitro and in vivo trials in both experimental animals and humans and also provide perspectives on probiotics' probable antiviral mechanisms. Although the initial findings are promising, the current research is limited by small sample sizes, short study durations, and a lack of diversity in population groups. Consequently, further research with larger, more diverse cohorts and extended follow-up periods is necessary to thoroughly assess and confirm the effectiveness of this probiotic treatment against these severe infectious diseases.}, }

During the COVID-19 pandemic, nursing care in some countries faced more challenges. One of these challenges was missed nursing care. This scoping review aims to identify and map the factors influencing missed nursing care in hospital settings during the COVID-19 pandemic in studies conducted in developed and developing countries.<br><br>METHODS: A scoping review was conducted according to methodology recommended by the Joanna Briggs Institute (JBI). We searched five databases-PubMed, Scopus, CINAHL, ProQuest, and Web of Science-as well as the Google Scholar search engine, from December 2019 to July 2025. Keywords of the study were selected according to the Medical Subject Headings (MeSH) and previous research. We included studies in hospital wards that examined missed nursing care and related concepts, specifically those whose data collection periods occurred during the COVID-19 pandemic. Language restrictions were not applied. The factors were derived inductively, considering conceptual similarities, relevance to the core themes, and similarities in meaning, including aspects related to the missed nursing care model, the developed model derived from it related to the factors considered for missed nursing care, and emerging challenges introduced by COVID-19. Findings were reported following the PRISMA-ScR.<br><br>FINDINGS: From the 1966 studies, we included 57 articles in the final review. Among them, 50 were cross-sectional, four were qualitative, two were mixed, and one was quasiexperimental. They were conducted mainly in Iran and the hospital units. Four main themes and nine subthemes emerged (1) work environment (structure, work climate), (2) nurse characteristics (individual and professional, personal), (3) workflow characteristics (intensity, predictability, risk), (4) country (developed, developing). Although the lack of human resources was reported in most studies, it was not the most significant contributing factor.<br><br>CONCLUSION: These findings can inform the development of strategies to address underlying factors affecting workflow, such as nurses' attitudes and the work environment, thereby enhancing adaptability to future global health crises and serving as a crucial policy foundation for mitigating the missed nursing care during health emergencies.<br><br>PRACTICAL IMPLICATIONS: These findings not only complement other global research exploring the reasons behind missed cares in nursing but also offer a framework for understanding and anticipating reported instances of missed care, enabling targeted interventions to address them effectively.}, }

Traditional vaccine approaches have achieved tremendous successes but often fall short for pathogens like Mycobacterium tuberculosis (TB), which evades host immunity through complex mechanisms, and for multidrug-resistant ESKAPE bacteria, where antibiotic resistance and antigenic variability complicate effective vaccine development. The COVID-19 pandemic spurred unprecedented advances in vaccine technology - particularly mRNA vaccines - reviving interest in novel platforms for bacterial diseases. Here we review next-generation vaccine strategies, focusing on nucleic acid-based platforms such as mRNA, DNA, and self-amplifying RNA (saRNA), as well as viral vector vaccines. We also examine nanoparticle technologies that serve as delivery systems or adjuvant platforms across these approaches. We discuss the unique opportunities of mRNA vaccines to induce both robust antibody and T-cell responses required for intracellular infections like TB, as well as the challenges of antigen discovery and delivery (e.g. lipid nanoparticles). Each platform's mechanism, immunogenic profile, current development status, and challenges are analyzed, including comparative insights. We highlight recent progress such as mRNA vaccine candidates against TB entering clinical trials and saRNA prototypes protecting against plague in animals. Finally, we provide a perspective on the future of vaccine strategies to combat antimicrobial resistance (AMR) - emphasizing the integration of multiple platforms, global collaborative efforts, regulatory pathways, and the translational hurdles that must be overcome to bring these next-generation vaccines from bench to bedside.}, }

This article provides a comprehensive review of the participation of Chinese vaccine companies in the global aid market, with particular attention to their changing roles, underlying motivations, and persistent challenges as latecomers from the Global South. Drawing on around 80 industry and policy documents, publicly available datasets, and 10 semi-structured interviews with industry and government stakeholders, this study uses documentary synthesis and thematic analysis to show that COVID-19 marked a critical turning point, accelerating Chinese vaccine manufacturers' international engagement while exposing persistent structural barriers. Unlike earlier studies, this review shows that Chinese vaccine enterprises' engagement in the global aid market is shaped not only by strategic market ambitions and alignment with national public health priorities, but also by enduring structural constraints such as geopolitical tensions, institutional mistrust, talent shortages, and reputational vulnerabilities. By situating Chinese enterprises within broader debates on non-state actors in global health, the study advances existing literature and offers policy-relevant insights to strengthen their capacity and influence in promoting equitable vaccine access.}, }

SARS-CoV-2 spike proteins interact with the human angiotensin-converting enzyme 2 (ACE2) receptor, together with accessory molecules that facilitate viral entry, through its spike receptor-binding domain (RBD). Although ACE2 is the primary receptor required for viral replication, its expression patterns do not fully correlate with viral distribution or tissue pathology. Moreover, SARS-CoV-2 has been shown to infect cells and tissues lacking detectable ACE2 expression. Viral entry via ACE2-independent pathways may also confer resistance to some monoclonal antibodies (Abs) targeting the spike RBD that block ACE2-mediated binding. These observations highlight the potential significance of ACE2-independent entry factors in SARS-CoV-2 infection, particularly in vaccinated individuals with Abs directed against ACE2-dependent viral entry. In this review, we discuss the emerging roles of ACE2-independent entry factors in SARS-CoV-2 infection and the immune responses. These factors include CD147, AXL, CD169/Siglec-1, CD209L, CD209, CLEC4G, ASGR1, LDLRAD3, TMEM30A, TMEM106B, transferrin receptor 1, GPR78, integrin α5β1, KREMEN1, LFA-1, and CD4. While ACE2 remains central to viral replication, ACE2-independent entry appears sufficient to elicit immune responses. Therefore, future investigations are warranted to elucidate the roles of ACE2-independent mechanisms in immune-mediated pathology and viral evolution, independent of immune pressure targeting ACE2-mediated entry in previously infected or vaccinated individuals.}, }

Owing to these facts, the first empirical study intends to investigate the empirical relationship between COVID-19, environmental pollution, and food shortage. We employ rolling window multiple correlation analysis on worldwide daily data of COVID-19 cases, carbon emissions, and food shortage news index from 22nd January 2020 to 29th November 2021. The results reveal a significant correlation between bivariate and multivariate cases over time. In bivariate cases, we find asymmetric but insignificant correlations between COVID-19 vs. food security and food security vs. CO2 emissions, except for a significant interconnection between COVID-19 vs. CO2 emissions at different periods.

However, this syndrome is poorly understood and has been recorded to include many systemic manifestations, including neurological, respiratory, cardiovascular, gastrointestinal, dermatological, psychosocial, and metabolic systems. Constitutional symptoms also include fatigue, insomnia, body weight changes, poor attention span, hair loss, sexual dysfunction, myalgia, and joint pain, with fatigue being the most common. Given the various proposed mechanisms published in the literature, the postulated mechanisms and pathways are discussed in this paper to contribute to the understanding of defining this syndrome. In this review article, the authors first explored how endothelial damage from COVID infection can lead to a hypercoagulable state. In addition, the effects of an insufficient initial immune response can lead to viral persistence alongside a potentially prolonged hyperactive immune response that includes a cytokine storm and mast cell activation syndrome. Furthermore, the viral persistence can be exacerbated by antibody-dependent enhancement or complicated by molecular mimicry. Current pharmacological therapies are explored and evaluated to investigate their efficacy in addressing this complex and chronic presentation. This review article has been written after an extensive literature review to increase the understanding and awareness regarding Long COVID, as a sincere effort to direct further research for an effective diagnosis and management.}, }

Even single amino acid substitutions might impact viral invasion, receptor binding, immune evasion, or transmissibility, as illustrated by recent influenza, SARS-CoV-2 and other emerging viruses' outbreaks. Understanding these processes requires linking molecular variation to phenotypic consequences. This review summarizes five experimental and computational technologies-pseudovirus systems, minigenome assays, display systems, deep mutational scanning (DMS), and in silico modeling-that together form an iterative framework for studying viral adaptation. A representative integration of DMS with reverse genetics has validated computationally predicted escape mutations and revealed trade-offs between binding and replication that conventional assays could not capture. We discuss each approach's strengths and limitations, highlighting how their coordinated use supports mechanism-based evaluation and data-driven design of vaccines and antiviral strategies.}, }

Studies have reported elevated levels of autoimmune antibodies in patients with Coronavirus Disease-19 (COVID-19), however, the exact prevalence remains poorly undocumented. This study aims to evaluate the prevalence of autoantibodies in COVID-19 patients compared to unaffected individuals.<br><br>METHODS: Electronic searches were conducted using the Cochrane Library, PubMed, Embase, Web of Science, Chinese Biological Medicine Database (CBM), China National Knowledge Infrastructure (CNKI), WANFANG, and Chinese Weipu (VIP). The case-control studies investigating the presence of autoantibodies in the serum of COVID-19 patients and control subjects published were included in this meta-analysis. The search covered November 2019, to December 2025. Studies were rigorously screened based on predefined inclusion and exclusion criteria. Quality assessment was performed using a modified version of the Newcastle-Ottawa scale (NOS). The odds ratios (ORs) for autoantibody seropositivity were calculated using RevMan 5.3. Sensitivity analysis was conducted to evaluate the stability results, and publication bias was assessed using Egger&#x2019;s test and funnel plot.<br><br>RESULTS: A total of 17 studies involving 1652 COVID-19 patients and 1455 control subjects met eligibility criteria for inclusion in the meta-analysis. The overall OR for antinuclear antibodies (ANAs) was 2.90 [95% confidence interval (CI): 1.36&#x2013;6.18], for anti-cardiolipin antibodies (ACAs) was 3.34 (95% CI: 2.14&#x2013;5.21), for anti-&#x3b2;2-glycoprotein 1 antibodies (anti-&#x3b2;2GP1) was 1.87 (95% CI: 1.00&#x2013;3.49) and that for anti-cytoplasmic neutrophil antibodies (ANCAs) was 8.49 (95% CI: 3.38&#x2013;21.33). Among the 11 studies assessing ANAs, the quality varied widely, resulting in considerable heterogeneity in the meta-analysis results. Heterogeneity across studies on ANAs may partially stem from differences in assay manufacturers as well as variations in the working cut-off dilution used for IIF. Egger&#x2019;s test reports indicated statistically significant publication bias among the included studies on ANAs.<br><br>CONCLUSIONS: This study suggests a higher seroprevalence of autoantibodies, including ANAs, ACAs, anti-&#x3b2;2GP1, and ANCAs in COVID-19 patients compared to control subjects.

In December 2024, there was news about increased cases of human metapneumovirus (HMPV) in China, when 6.2% and 5.4% of positive respiratory illnesses and admissions, respectively, were linked to HMPV, surpassing adenovirus, rhinovirus, and COVID-19. There have been concerns about it becoming another epidemic, and by implication, a pandemic, especially as the world is gradually recovering from COVID-19 and its devastating impacts. Currently, there is no directly acting antiviral drug targeting HMPV, and this has left a gap in its treatment and management, especially in the young, elderly, and immunocompromised, who are prone to having severe manifestations. As the immune system is crucial in fighting and eliminating the infection, modulating the immune system directly or indirectly can treat HMPV. The lung that was initially known to be sterile is now found to house different populations of microorganisms, including bacteriome, virome, and mycobiome. The lung microbiome modulates HMPV infection. The presence of pathobionts like H. influenzae enhances HMPV infection and severity. The detection of the microbiome was made possible by the advent of cutting-edge technologies like next-generation sequencing and bioinformatics tools. The combination of Recombinase Polymerase Assay, CRISPR-Cas12a, and Fluorescence Assay has been used in the rapid detection of HMPV in China. The microbiome plays a crucial role in shaping the immune system. Exploring such can be a way of managing HMPV. Probiotics, prebiotics, and postbiotics are ways in which the microbiota can be manipulated to limit adverse drug reactions. These can be explored in HMPV diagnosis, treatment, and prevention.}, }

We synthesized published literature, official reports, and surveillance data, analyzing COVID-19 transmission using the epidemiological triangle model. Comparative case studies from South Korea, New Zealand, and the United Kingdom were examined to assess intervention effectiveness. National surveillance systems, outbreak response mechanisms, and public communication strategies were critically reviewed. Our findings show that disparities in testing, data transparency, and infrastructure shaped outcomes globally. Surprisingly, many high-income countries underperformed despite prior preparedness rankings. Countries implementing early lockdowns, equitable vaccine rollouts, and consistent public messaging achieved better control. However, asymptomatic transmission, weak surveillance integration, and delayed policy actions hindered containment. Vaccine inequity and fragmented data systems further limited coordinated response. Future preparedness must emphasize early interventions, sustained surveillance investment, transparent communication, and equitable access to care.

The COVID-19 pandemic has exacerbated the problem by increasing alcohol abuse and hospitalisations for ALD. Since there are no approved therapies for ALD, promoting abstinence from alcohol is the primary approach. However, the mechanisms by which alcohol induces fat accumulation in the liver, the disease's initial stage, are not fully understood. This knowledge gap hampers the development of new treatments for ALD. This review aims to explore research on alcohol-induced fatty liver and compare it with metabolic-associated fatty liver disease. The goal is to merge these findings with current knowledge of ALD and hepatic lipid metabolism, including fatty acid oxidation, lipogenesis, and very-low-density lipoprotein (VLDL) secretion. Besides lipid metabolism, factors like inflammation, oxidative stress, cellular hypoxia, and autophagy also contribute to ALD's development and progression. By identifying gaps in understanding the molecular mechanisms of ALD progression, this review suggests future research directions.

Among cordyceps types, Cordyceps militaris (CM) is the most commercially useful owing to its ease of artificial cultivation for mass production. In contrast, other types, such as Ophiocordyceps sinensis, are expensive and difficult to collect. Therefore, numerous studies have explored the therapeutic potential and active constituents of CM. The therapeutic use of CM is based on its various pharmacological activities, including immunomodulatory, anti-tumor, antioxidant, anti-diabetic, anti-obesity, and neuroprotective activities, of which the immunomodulatory effects have been the most studied. CM contains active constituents such as nucleosides (cordycepin and adenosine), polysaccharides, peptides, proteins, sterols, glycolipids, and carotenoids. Recent studies show that CM extract, cordycepin, and polysaccharides exert immunomodulatory effects in response to the immune environments. They enhance innate and cell-mediated adaptive immunity not only under normal conditions but also in immunosuppressed states induced by cyclophosphamide, interleukin-4, tumor culture supernatant, methotrexate, cancer cell-line-xenografts, influenza virus, and severe acute respiratory syndrome coronavirus 2. Meanwhile, they suppress an overactivated immune system stimulated by factors such as angiotensin II ± vascular endothelial growth factors, concanavalin A, 2,4-dinitrophenyl (DNP)-serum albumin ± DNP-specific immunoglobulin E, lipopolysaccharide (LPS), lipoteichoic acid, phytohemagglutinin, phorbol myristate acetate plus calcium ionophore A23187, calcium chloride, cecal ligation and puncture ± LPS, dextran sodium sulfate, monosodium iodoacetate, ovalbumin, myelin oligodendrocyte glycoprotein 25-35, monosodium urate, and Western diet by ameliorating innate and humoral adaptive immune responses. This study reviewed recent and notable literature evaluating the immunomodulatory potentials of CM extract, cordycepin, and polysaccharides.

This scoping review aims to identify and synthesise evidence from suicide and self-harm prevention interventions implemented in all types of humanitarian settings, globally, that have been evaluated for their effectiveness in improving suicide and self-harm-related outcomes. We systematically searched eight electronic databases, including two grey literature databases, and relevant organisational websites for records published through November 2024 and in any language. Screening was done using the Covidence platform, with each record independently screened by two reviewers. Among other preselected inclusion criteria, studies must have conducted a quantitative evaluation of the effectiveness of an intervention on improving suicide and self-harm-related outcomes during a humanitarian crisis to be included for data extraction. Data extraction and quality assessment were both conducted by two authors. In all, 6,209 records were screened at the title and abstract phase; 104 were included for full text screening; and 23 studies were included for data extraction. Most studies were conducted during the coronavirus disease 2019 pandemic (COVID-19), and in high-income countries. Evaluated interventions encompassed various approaches, including psychotherapeutic, practical, and pharmacological assistance, often employing multiple components. The majority targeted the general population, were delivered via remote modalities and relied on mental health specialists for their administration. Overall, 15 (65.2%) interventions were associated with statistically significant positive effects on suicide and or self-harm-related outcomes. Promising approaches include cognitive behavioural therapy-based text services, skills-building programmes, and strategies that foster supportive environments for high-risk individuals. These findings highlight both promising approaches and critical gaps in suicide prevention efforts in humanitarian settings. The limited evidence base - particularly in LMICs and with particularly at-risk populations - alongside the increasing frequency of humanitarian crises, underscores the urgent need for future implementation and associated research of suicide and self-harm prevention initiatives within humanitarian contexts.}, }

Although often overshadowed by respiratory syncytial virus (RSV) and influenza, hMPV contributes substantially to the global burden of respiratory disease, particularly among young children, older adults, and immunocompromised populations. The COVID-19 pandemic further altered the epidemiology of respiratory viruses, disrupting established seasonal patterns and creating immunity gaps that have fueled unusual hMPV outbreaks in recent years. Despite its clinical relevance, hMPV remains underdiagnosed due to limited awareness, restricted access to reliable diagnostic tools, and frequent co-infections that obscure its contribution to disease severity. Currently, no licensed antivirals or vaccines exist, leaving supportive care as the only treatment option. Ongoing research into monoclonal antibodies, vaccine candidates, and combined RSV-hMPV preventive strategies offers promise but remains in early stages. In the context of global interconnectedness and the demonstrated capacity of respiratory viruses to cause widespread disruption, hMPV raises important concerns as a potential emerging public health threat. While unlikely to cause pandemic-scale disruption, hMPV's endemic circulation and disproportionate impact on vulnerable populations warrant its recognition as an emerging threat demanding proactive public health intervention and sustained investment in prevention strategies. This review examines hMPV's evolving role as a public health threat in the post-COVID-19 landscape, where altered epidemiological patterns and increased surveillance have highlighted its underappreciated impact.}, }

Although there is not yet a true cure for Long COVID, many patients benefit substantially from rehabilitation strategies, medications, and social support resources that are available in Missouri. The purpose of this article is to review the definition and epidemiology of Long COVID, provide practical guidance for Long COVID assessment and management especially in the primary care setting, and increase awareness of regional resources for people in Missouri who are living with Long COVID and for the clinicians who are caring for them.}, }

In August 2024, Colombia reported 6 million infections and a 2.2% mortality rate related to COVID-19. Post-COVID-19 syndrome (PCS) is a chronic condition occurring after the acute infection, typically characterized by fatigue, weakness, pain, and sarcopenia, impacting the patient's quality of life (QoL). This systematic review aimed to identify musculoskeletal sequelae, including peripheral muscle strength, fatigue, and QoL, in patients with PCS. Methods: We searched the PubMed, Scopus, and Web of Science databases for cross-sectional, case-control, and cohort studies focusing on musculoskeletal sequelae in patients with COVID-19 infection published between 2020 and 2025. Study quality and risk of bias were assessed using the MINORS and the ROBINS-E scales, respectively. Results: Thirteen studies (n = 5657 patients) met the eligibility criteria. Seventy-six percent of studies indicated muscle weakness as the most common sequela, primarily in older adults and individuals with comorbidities (obesity, diabetes, and chronic obstructive pulmonary disease). General fatigue (reported in 76% of the studies) significantly influenced patients' daily lives, whereas 90% of patients reported some level of deterioration in their QoL, primarily regarding mental health, bodily pain, and physical performance. Conclusions: Patients with PCS who required mechanical ventilation showed reduced muscle strength and poor physical performance, especially older adults. Inactive individuals had worse musculoskeletal sequelae, while physical activity was associated with better strength levels. Although QoL improved after 12 months, the combination of aerobic exercise with adequate nutrition is essential to promote muscle recovery, reduce fatigue, and improve overall functional capacity in post-COVID-19 patients.}, }

Even though existing studies have reported structural changes in the post-COVID-19 period, the results remain highly inconsistent and controversial. As such, identifying an imaging biomarker for post-COVID brains is still under investigation. This review aims to comprehensively summarize the structural MRI (sMRI) studies that focus on volumetric brain changes at least two weeks following COVID-19 infection. Methods: A systematic literature search was conducted on PubMed, SCOPUS, Web of Science, EMBASE, and Google Scholar up to 9 September 2025. Studies that utilized sMRI to assess volumetric brain changes post-COVID at greater than two weeks following infection were included. Exclusion criteria encompassed research involving pediatric or adolescent populations and imaging modalities other than sMRI. Preprints, reviews, case reports, case series and post-mortem studies were also excluded. Results: Forty-one studies satisfied the inclusion criteria and consisted of 2895 patients and 1729 healthy controls. Despite the wide variability in image acquisition protocols, data processing methods, and comorbidities between studies, multiple studies reported statistically significant volumetric reductions in the hippocampus, amygdala, thalamus, basal ganglia, nucleus accumbens and the cerebellum months to years after infection, especially in older hospitalized patients with severe COVID-19. Conclusions: The emerging literature reports long-term volume changes across various brain regions in individuals previously infected with COVID-19; however, the evidence is inconsistent. Specific imaging biomarkers following exposure to SARS-CoV-2 infection and the underlying mechanisms of these changes are yet to be identified. Future studies with harmonized imaging protocols, longitudinal designs, and integrated biomarker and clinical data are needed to define robust biomarkers and elucidate the pathophysiology of these findings.}, }

These VOCs provide valuable information about metabolic markers linked with COVID-19. They have opened opportunities to develop sensors for COVID-19 screening based on breath analysis. These sensors have the potential to provide the rapid detection of viruses in healthcare settings. RT-PCR, as a conventionally adopted diagnostic method, has a detection limit around 10-100 RNA copies/mL, with an accuracy of around 95%. Gas sensors have demonstrated VOC detection limits at the ppm level in COVID-19 EB and have displayed a sensitivity and specificity of 98.2% and 74.3%, respectively. Multiple gas sensors combined with machine learning algorithms have the potential to enhance the specificity of VOC detection. In addition to having an accuracy similar to that of the PCR method, the VOC-based diagnosis of COVID-19 offers unique advantages in terms of non-invasive and rapid detection. This review provides an overview of state-of-the-art gas sensors developed for COVID-19 detection. Despite there being significant developments in this field, there are certain challenges that still need to be addressed-these include the impact of environmental factors, the specificity of detection, the sensing range, and precision limitations, leading to accuracy issues. Despite these existing challenges, the integration of gas sensors with machine learning methods can enhance the accuracy of the detection of COVID-19. Future research directions are proposed to validate and standardize the application of gas sensors for COVID-19 in clinical settings.}, }

While the epidemiological evidence points to a disruption in the early- and mid-stage diagnostic process, which causes a shift to late-stage lung cancer discovery with no impact on its actual prevalence, an alternative hypothesis based on the intersection of viral and cancer biology could have a real effect on lung carcinogenesis as an independent phenomenon. By weaving together population-level trends, mechanistic insights, and translational oncology, we discuss whether the pandemic-associated decline in lung cancer diagnoses reflects primarily a temporary diagnostic artifact or whether it also reveals biologically relevant intersections between SARS-CoV-2 and pulmonary oncogenesis. The COVID-19 pandemic, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has exerted profound and multifaceted effects on global healthcare systems, altering patterns of disease detection, management, and outcomes across nearly all medical disciplines. These disruptions generated what has been termed a "diagnostic deficit", producing a backlog of undetected cancers that have only partially been recovered in subsequent years. This phenomenon, sometimes described as a "COVID-19 debt" in oncology, is thought to contribute to excess late-stage diagnoses and potentially worse medium-term survival outcomes. Beyond the disruption of medical systems, the pandemic also raised a more speculative but biologically intriguing question: could SARS-CoV-2 infection itself, through direct or indirect mechanisms, influence lung cancer biology? Our review aims to critically synthesize the evidence across seven domains to address this dual hypothesis. (1) We examine the observed effects of the pandemic on cancer incidence, highlighting global registry and health-system data; (2) we review SARS-CoV-2 infection biology, including viral entry, replication, protein functions, and treatment implications; (3) we summarize the pathogenesis of lung cancer; (4) we explore the role of immune checkpoints in tumor immune evasion, followed by (5) analyses of immune dysregulation in acute infection and (6) in long COVID; and (7) finally, we evaluate proposed oncogenic mechanisms of SARS-CoV-2, integrating molecular virology with cancer immunology. We conclude that the "diagnostic deficit" phenomenon was a reality during and immediately post-pandemic. However, a definitive answer to the questions related to the impact of the infection as an independent phenomenon would require advanced research information covering the biology of the viral infection and lung cancer oncogenesis: processes that are not currently implemented in routine clinical laboratory investigations.}, }

While valued since the 1960s for its ability to inhibit bacterial fatty acid synthesis, its environmental persistence, ecotoxicity, and bioaccumulative potential have raised significant global concern. The increased use of disinfectants during the COVID-19 pandemic has further exacerbated its prevalence as an aquatic pollutant. In the environment, TCS is distributed through water bodies and sediments, undergoing processes such as biodegradation and photochemical degradation. Its bioaccumulation poses a substantial threat to aquatic organisms, particularly fish. A growing body of research indicates that TCS acts as an endocrine disruptor and developmental toxicant, with documented adverse effects encompassing impaired embryonic and larval development, skeletal malformations, and induction of oxidative stress, mitochondrial dysfunction, DNA damage, and inflammatory responses. Furthermore, TCS exposure is linked to reproductive toxicity, including altered sex hormone levels and diminished reproductive capacity. This review consolidates current knowledge on the chemical properties, environmental fate, biodegradation pathways, and ecotoxicological impacts of TCS, with a specific emphasis on its multifaceted health risks to fish. The synthesis aims to provide a foundation for future research, inform environmental risk assessments, and support the development of evidence-based regulatory measures.}, }

This systematic review and meta-analysis aimed to synthesize evidence on the impact of FCN interventions on QoL and clinical outcomes in post-COVID and people living with chronic conditions managed in community and home settings. Methods: Following PRISMA 2020 guidelines, we searched PubMed, Scopus, CINAHL, PsycINFO, Embase, and Cochrane Library (January 2020-November 2024). Eligible studies were randomized controlled trials evaluating FCN-led interventions. Primary outcomes were QoL (measured with validated tools) and glycemic control (HbA1c). Secondary outcomes included hospital readmissions, anxiety, depression, and self-care abilities. Risk of bias was assessed using the Cochrane RoB2 tool for randomized controlled trials. Random-effects meta-analyses were performed, with heterogeneity evaluated by I[2]. The protocol was prospectively registered in PROSPERO (CRD42024567890) before data extraction. Results: Seventy-one studies (n = 19,390) were included. Interventions comprised home visits, telehealth, patient education, and case management. Pooled analyses demonstrated significant improvement in QoL (SMD 0.34, 95% CI 0.18-0.50) and reduction in HbA1c (-0.47%, 95% CI -0.69 to -0.25). FCN interventions also reduced hospital readmissions (RR 0.74, 95% CI 0.62-0.89) and improved mental health outcomes. Most studies were judged at low to moderate risk of bias. Conclusions: FCN-led interventions significantly enhance QoL, mental health, and clinical outcomes while reducing hospital readmissions. These findings highlight the strategic importance of integrating FCNs into community-based healthcare models.}, }

In Australia, there is a funded immunisation program for both adults and children aimed at preventing and controlling vaccine-preventable respiratory infections (VPRI), such as pneumococcal disease (PD), influenza A/B, respiratory syncytial virus (RSV) infection, and COVID-19. This narrative review outlines the current Australian adult and paediatric immunisation guidance for VPRIs. It also examines the literature that supports the current risk group recommendations, including the clinical and economic burden of VPRIs, vaccination effectiveness, and coverage. Gaps in current risk group definitions, as well as additional risk groups that could be included in vaccine recommendations, are also discussed. Further research is needed to determine the optimum age for vaccination in adults which may enable alignment of age recommendations across different VPRIs. Individuals with multiple risk factors, commonly referred to as risk stacking, are at a greater risk of developing severe disease for VPRIs. This emphasises the importance of vaccinating these individuals. More research is needed to evaluate the effectiveness of vaccines in older adults and to create more effective vaccines for high-risk paediatric groups, such as those with compromised immunity or for children who have undergone haematopoietic stem cell transplantation.}, }

This review examines the impact of the administration of prime and booster vaccine doses in the same (ipsilateral) versus the opposite arms (contralateral) on vaccine immunogenicity. We review animal model and human studies evaluating the impact of ipsilateral versus contralateral COVID-19 and non-COVID-19 vaccine boosting on immunologic outcomes with a focus on the germinal center response, antibody production, and T cell activation. While some studies suggest that ipsilateral administration may enhance the quality of germinal center B cell responses and antibody magnitude, data across different studies have been inconsistent. Relatively few studies have compared ipsilateral versus contralateral boosting, and differences in study design and outcomes have limited the ability to draw conclusions as to whether one is superior to the other. This review highlights a noteworthy and underexplored area in vaccinology and the need for future research to clarify whether ipsilateral/contralateral boosting strategies matter. To answer this question, high-quality, randomized controlled trials evaluating different types of vaccines that consider immunologic mechanisms, capture key time points and appropriate specimens, and evaluate early and long-term immunogenicity endpoints are required.}, }

Scholars across disciplines proposed numerous-and often competing-terms and theories to explain these disparities. In this review and within the context of the COVID-19 pandemic, we assess the usage, definition, and appropriateness of these terms and their linked theories or frameworks. Methods: We conducted a scoping review aiming to clarify key definitions, concepts, and frameworks of eight prominent terms used in the literature regarding COVID-19 global and/or regional vaccine inequities (i.e., vaccine nationalism, vaccine apartheid, vaccine colonialism, vaccine imperialism, vaccine racism, vaccine diplomacy, vaccine solidarity, and vaccine internationalism). The methodology followed the Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines for Scoping Reviews and included papers from January 2020 to the end of October 2024. Results: We included 79 papers in our study. The majority (71%) were published in 2021-2022, with less than one-quarter authored by scholars from LMICs. Vaccine imperialism was consistently defined but rarely used, while vaccine nationalism and vaccine apartheid appeared more frequently with varied meanings. Yet, in most cases, all of these concepts identified economic interests of vaccine-producing countries as the root cause of the observed vaccine inequities. Vaccine diplomacy showed similar ambiguity, viewed by some as worsening inequities and by others as potentially mitigating them. The terms vaccine racism, vaccine colonialism, and vaccine solidarity were not explicitly identified but appear to be embedded within the definitions of other prominent terms detected. Conclusions: Across the preselected terms examined, we found numerous-and often conflicting-definitions, revealing the fragmented and competing understandings of the major drivers fueling global vaccine inequities. This lack of coherence inhibits evidence synthesis or shared theoretical progress but, most importantly, might undermine current and future efforts to address these inequities.}, }

Pipelines, including decentralized approaches and federated learning, are now being built that will democratize access and facilitate the next generation of AI tools for the global epilepsy community. Despite this, enduring issues remain incompletely addressed. For example, AI requires high volumes of data, leading to concerns about ethical ownership, stewardship, and privacy. Few AI-based tools have progressed from derivation to validation stages, and only rare exceptions undergo real-world evaluation. Inadvertent harmful algorithmic and decision allocation biases also continue to represent major risks to the global epilepsy population. Additional barriers include geographical disparities in computing resources, proprietary ownership of electronic health records, EEG, and brain-imaging platforms, and greenhouse gas emissions related to the demanding power requirements of AI. Therefore, to fully avail ourselves of the benefits of AI, we assert that ethical, equitable, and effective AI for epilepsy requires collaboration from the entirety of the global epilepsy community.

Mobile Addiction Treatment Units (MATU) are vans, vehicles, or portable clinics that provide low-threshold, low-barrier, community-based services for addiction treatment including opioid agonist medications. MATUs are a point of entry for care, particularly for individuals who have faced barriers to access at in-person healthcare facilities.<br><br>OBJECTIVE: This narrative review aims to synthesize and conduct a thematic analysis of the research on implementation and outcomes of MATUs in the United States. Our study's primary objectives were threefold: 1) to evaluate MATU program reach, 2) to evaluate MATU program effectiveness, and 3) to evaluate MATU program implementation.<br><br>METHODS: We identified studies examining MATUs by searching electronic databases MEDLINE (Ovid), Embase (Elsevier), PsycINFO (EBSCO), and Web of Science Core Collection (Clarivate). Records were selected for full-text review if their abstract referenced any mobile modality for substance use treatments. Exclusion criteria included review articles, opinion articles, theoretical articles, abstracts, dissertations, studies conducted outside of the United States, and studies focused solely on mobile harm-reduction interventions without offering medication treatment for SUD. This review is reported per the Preferred Reporting Items of Systematic Reviews and Meta-Analyses for Scoping Review (PRISMA-ScR) guidelines.<br><br>RESULTS: A total of 2,232 articles were screened at the title and abstract level, of which 83 were assessed for full text eligibility. The 34 articles selected for inclusion were varied in methodology, and included randomized controlled trials (RCTs), observational studies, cohort studies, and mixed-methods research. The most common study locations were Baltimore, MD (10 studies), Boston, MA (5 studies), Philadelphia, PA (4 studies), and New Haven, CT (3 studies). Regarding reach, four studies were conducted during the COVID-19 pandemic. Six studies were conducted primarily in a population experiencing homelessness; two studies were conducted primarily in populations with criminal justice involvement; four studies were conducted primarily in youth or young-adult populations; three studies were conducted in rural populations. In these settings, MATUs successfully engaged vulnerable and underserved populations, delivering comprehensive care that combined harm reduction, primary care, and mental health services. These units demonstrated potential to enhance health outcomes, reduce stigma, increase treatment retention rates in marginalized populations compared to office-based programs, and tackle social determinants of health. Common challenges included patient engagement, logistical and regulatory barriers, and financial sustainability, all compounded by limited space, staffing, and resources, while homelessness, encampment removals, and the COVID-19 pandemic further disrupted care continuity (J Subst Abuse Treat 120:108149, 2021; Front Public Health 11:1154813, 2023; J Subst Use Addict Treat 159:209272, 2024; J Subst Use Addict Treat 164, 2024; Health Place 28:153-66, 2014; Addict Sci Clin Pract 18:71, 2023).<br><br>CONCLUSION: MATUs proved to be innovative and effective in addressing OUD and related issues for vulnerable populations traditionally lacking access to care. However, ongoing efforts to overcome implementation challenges and ensure sustainable funding and resources are crucial for their continued success and expansion. Future research should focus on large-scale, quantitative studies, particularly in diverse and rural settings, to better understand their long-term impact and sustainability.}, }

Of all the identified structural proteins and non-structural proteins within the coronaviruses, nucleocapsid (N) protein is highly conserved and is the most abundant viral protein in infected host cells. N protein regulates the more complex and diverse mechanisms through which viruses suppress host immunity. In this review, we analyzed the basic structure of coronavirus N protein, and further elaborate on its multifaceted regulatory functions in the virion assembly, pathogenesis, host innate immune responses, as well as the innate immunity-related programmed cell death and cell cycle, and also other cell processes. A better understanding of the immune evasion strategy regulated by N protein will help to provide a theoretical basis for the development of broad-spectrum anti-coronavirus drugs targeting N proteins.}, }

MRJPs are the primary constituents of RJ and have demonstrated significant potential as antiviral agents. MRJPs exhibit antiviral effects against various viruses, including HCV, HBV, HIV, and SARS-CoV-2. Previous research has indicated that MRJPs can interfere with viral replication by targeting specific stages of the viral life cycle, such as by inhibiting key enzymes, including RNA-dependent RNA polymerase and reverse transcriptase. They also block viral entry into host cells and influence immune responses. In addition to their direct antiviral actions, MRJPs exhibit antioxidant, anti-inflammatory, and immunomodulatory properties, further enhancing their therapeutic potential. Despite these promising preclinical findings, further mechanistic and translational investigations are required to validate and enhance the therapeutic potential of MRJPs.

The need for species typing in diagnostics is also becoming more pressing with the emergence of drug-resistance, especially of Leishmania tropica. Serological tests are unable to do this, while techniques that can, like PCR, require complex and expensive machinery. Isothermal assays like LAMP offer a promising solution, but more work also remains, as few species-specific LAMP assays have been developed thus far and CL in Ethiopia is particularly neglected. Additionally, since the COVID-19 pandemic, many cheap isothermal diagnostic devices have been produced, which have yet to be tested in the diagnosis of CL.

Neurological examination presented with pyramidal tract signs and sensory deficits in both lower limbs. Cerebrospinal fluid oligoclonal bands were positive. Brain MRI showed subtle corticospinal tract hyperintensities, whereas spinal MRI findings remained normal throughout the course. Somatosensory-evoked potentials (SEP) demonstrated absent right N20 and bilateral P37 responses, localizing dysfunction to the thoracic cord. Treatment with intravenous methylprednisolone pulse therapy with plasma exchange resulted in marked clinical recovery and SEP normalization, with only mild residual paresthesia at two-year follow-up.<br><br>DISCUSSION: The present case illustrates the clinical utility of SEPs for monitoring disease activity and establishing objective criteria for treatment escalation in post-COVID-19 MRI-negative myelitis.

It creates a critical gap for rapid, accessible, portable and non-invasive health assessment. AI-powered Nanosensors for Breathomics Diagnostics (AND) platforms have emerged as a transformative solution to this complex global problem, integrating highly sensitive nanomaterials with advanced machine intelligence to detect disease biomarkers in exhaled breath. These platforms have already demonstrated high performance, with reports of 90-95% diagnostic accuracy for conditions such as lung cancer and achieving sub-ppb detection limits. These platforms are not limited to controlled laboratory settings but have been employed to monitor a spectrum of diseases, including cancer, asthma, diabetes, coronavirus disease, and renal failure. Their integration into wearable systems, smartphones, smart masks and multimodal laboratory systems further extends their applications in predictive analytics, personalised medicine and real-time human-machine interaction. However, challenges related to data standardisation, sensor selectivity, ethical AI, and clinical validation have limited their commercialization. It necessitates solutions such as Explainable AI, physics-informed modelling, network theory, and the development of large-scale clinical breath databases to enhance clinical reliability, model robustness, diagnose sensor drift, and attain transparency. This article critically details the recent progress and charts a new path forward for translating AND platforms from research to clinical reality as next-generation healthcare.}, }

We aim to quantify the relative risk of new-onset autoimmune diseases following COVID-19 and its modifiers through a systematic review and meta-analysis of population-based cohort studies. MEDLINE, Embase, Cochrane Library, and Web of Science were searched to March 31, 2025, for cohort studies comparing individuals with and without confirmed COVID-19. Random-effects meta-analysis estimated pooled hazard ratios (HRs) with 95% CIs. Subgroup analyses examined the severity of acute COVID-19, vaccination status, and demographics. Risk of bias was evaluated with the Newcastle-Ottawa Scale, certainty of evidence with GRADE, and publication bias with funnel plots and Egger's test. The review protocol was prospectively registered in PROSPERO (CRD42025646186). Seventeen cohort studies, including over 250 million person-years, were included. COVID-19 was associated with a 49% increased risk of new-onset autoimmune-related diseases (AIRD; HR = 1.49, 95% CI: 1.21-1.83; p = 0.0002). Significant associations (p < 0·05) were observed for 17 of 23 outcomes, with the strongest risks in antiphospholipid syndrome (HR = 2·16), ANCA-associated vasculitis (HR = 2·15), mixed connective tissue disease (HR = 2·12), and immune thrombocytopenic purpura (HR = 1·87). Risk was higher after severe infection (HR = 1.70), but was reduced in vaccinated individuals (HR = 0.56, compared to 1.42 in unvaccinated individuals). The certainty of evidence was moderate for conditions with large effect sizes, but low overall, reflecting heterogeneity across studies and the non-randomized design of the included studies. SARS-CoV-2 infection increases the risk of autoimmune diseases, particularly those affecting vascular and connective tissue. Risk is amplified by severe infection and attenuated by vaccination. These findings highlight the necessity of vaccination and targeted follow-up in severe COVID survivors.}, }

In addition, various government agencies have implemented "infectious disease preparedness" to mitigate future outbreaks. This review highlights conventional and advanced methods for infectious disease diagnosis with an emphasis on emerging mass spectrometry methods. Conventional methods for pathogen identification, such as culture-based techniques and molecular methods, have limitations with respect to sensitivity, specificity, and turnaround time. Recent advances in high-resolution mass spectrometry have revolutionized the field of infectious disease biomarker discovery. These techniques enable the comprehensive profiling of metabolites in various biological samples, identification of disease-specific biomarkers, and elucidation of complex host-pathogen interactions. While liquid chromatography-mass spectrometry has been extensively used to identify metabolic alterations in diseases, such as COVID-19, tuberculosis, pneumonia, and influenza, this often requires the use of body fluids. On the other hand, advances in gas chromatography-high resolution mass spectrometry are enabling noninvasive detection of infectious diseases by means of breath-based volatile organic compounds. These methods offer high sensitivity and specificity, enabling the detection of low-abundance biomolecules and the elucidation of complex biological pathways. This review further examines the limitations of each approach while emphasizing the essential applications of metabolomics in infectious disease diagnosis.}, }

While there has been significant focus on remote work in other sectors such as healthcare and tech industries, there have been no scoping reviews on remote service delivery in crime victim services. Using the PRISMA-ScR framework for scoping reviews, we identified 27 studies on remote or hybrid services in victim service agencies that met our inclusion criteria (empirical studies on remote and/or hybrid work in community- and/or systems-based victim service agencies, written in English). Studies were examined regarding the (a) methods and data used in empirical studies; (b) provider-level and client-level challenges and benefits; and (c) recommendations. Findings show that most studies were exploratory or descriptive in nature, collected qualitative data from service providers, and were conducted, at least in part, to learn about the impact of the COVID-19 pandemic. Common provider-level challenges included technological barriers, concerns about the security of online services, and the development of rapport with clients virtually, while strengths included personal-professional flexibility, new collaborations, and work productivity/efficiency. Client-level challenges included technology access, digital literacy, and confidentiality and safety concerns, while strengths included increased access to services, reduced cost, and increased anonymity of online services. Results suggest that we need additional, rigorous evaluation research to understand how processes and outcomes differ between remote and in-person services for crime victims and victim service providers.}, }

Innovations in the technologies used within healthcare services both influence and are influenced by the nursing profession and its practices. These technological developments help create new roles, support nurses in fulfilling their responsibilities, and enable the delivery of more efficient and safer patient care. To meet the demands of the future, nurses must adapt to emerging technologies and provide evidence-based care using these innovations. For instance, future gerontological nurses may act as care supervisors, overseeing robots tasked with monitoring vital signs, checking blood glucose levels, detecting pressure ulcers, or assessing fall risks. While technological advancements may reduce the demand for nursing labor, they also offer protective benefits. During the COVID-19 pandemic, the use of humanoid robots helped minimize the exposure of healthcare workers, including nurses, to the virus-thus reducing physical contact while maintaining essential care. In Wuhan, where the outbreak was first reported, robots were employed to perform tasks traditionally carried out by healthcare professionals, such as taking oral swabs, conducting basic diagnostics (e.g., using ultrasound or stethoscopes), cleaning and disinfecting patients, administering medications, delivering meals, and monitoring vital signs and body temperature. Despite a potential decrease in the number of nurses required for routine procedures, the demand for professional nurses to manage complex tasks and provide emotional care will increase. Therefore, this study aims not only to inform readers about the impact of technology on nursing practice and the profession but also to support future research in this area. To adequately prepare the nurses of tomorrow, it is essential for nurse educators, administrators, and students both undergraduate and graduate to embrace technology and actively work to expand their knowledge. Enhancing technological literacy is critical to ensuring competent and future-ready nursing professionals.}, }

The Caregiver Skills Training program aims to address this disparity by equipping caregivers with practical skills. This scoping review examines the cultural adaptations, facilitators, and barriers to the implementation of Caregiver Skills Training, focusing on its accessibility, feasibility, and acceptability. A comprehensive search of ERIC, PsycINFO, PubMed, and Web of Science identified eligible studies that reported cultural or linguistic adaptations of Caregiver Skills Training. Forward searches and manual reference checks supplemented the review. Data were extracted using the Cultural Adaptation Checklist framework and analyzed for patterns in adaptation, training, barriers, and facilitators. Seventeen studies across Asia, Africa, Europe, and North America highlighted diverse adaptations in language, content, and delivery methods. Facilitators included community partnerships and task-shifting with non-specialists, while barriers involved logistical challenges, stigma, and resource constraints. Caregiver Skills Training's flexible, culturally responsive framework makes it a viable model for scaling autism interventions globally. Tailored adaptations and strong support systems for facilitators are essential to overcoming systemic challenges and ensuring equitable access in low- and middle-income countries.Lay abstractHow the Caregiver Skills Training Program Helps Families WorldwideThe Caregiver Skills Training program was designed to help families of children with autism and other developmental challenges in low-resource settings. Caregiver Skills Training empowers parents and caregivers by teaching them practical strategies to improve their child's communication, social interaction, and daily living skills. This program is unique because it does not require a formal diagnosis and is designed to be delivered by trained non-specialists, such as community health workers. A review of 17 studies from different countries examined how the Caregiver Skills Training program was adapted to fit the cultural and practical needs of families in each region. For example, materials were translated, simplified, and paired with visual aids to help parents with lower literacy levels. Non-specialist facilitators helped make the program more accessible, and online or hybrid delivery methods increased participation during the COVID-19 pandemic. However, challenges remain. Families often face barriers like limited transportation, stigma, and lack of Internet access, which can prevent them from fully participating in the program. Facilitators also need more training and support to maintain program quality. Despite these obstacles, Caregiver Skills Training shows promise as a global solution to bridge the gap in autism care, especially in underserved communities. This review highlights the importance of adapting programs like Caregiver Skills Training to meet the unique needs of families worldwide, ensuring that every child has the opportunity to thrive, regardless of where they live.}, }

Under physiological conditions, it acts as a dynamic scaffold, interacting with monocarboxylate transporters (MCTs), integrins, and cyclophilin A (CyPA) to orchestrate spermatogenesis, embryo implantation, and neural network function. Pathological overexpression of CD147 induces the secretion of matrix metalloproteinases (MMPs), epithelial-mesenchymal transition (EMT), metabolic reprogramming, and immune evasion, functioning as an independent prognostic biomarker in multiple malignancies. Beyond oncology, CD147 is exploited as an entry receptor for pathogens, including SARS‑CoV‑2, HIV‑1, Plasmodium falciparum, and contributes mechanistically to cardiovascular, autoimmune, and neurodegenerative diseases. Notably, CD147 acts as a fundamental "Energy-Structure Coupler," coordinating metabolic flux (via MCTs) with morphogenetic plasticity (via integrins/MMPs) to maintain cellular homeostasis. This review summarizes current insights into CD147's molecular structure, isoforms, post-translational modifications, and signaling pathways, highlighting its pivotal roles across cancer, infection, autoimmunity, and cardiovascular disease. Finally, we discuss challenges such as the "specificity paradox" and propose emerging strategies to exploit CD147 as a precision biomarker and therapeutic target across diverse diseases.}, }

Direct viral injury to the endothelium and an exaggerated inflammatory "cytokine storm" and complement activation disrupt normal hemostasis and create a prothrombotic environment. This scoping review aims to synthesize and compare the mechanisms, risk factors, and antithrombotic strategies associated with venous and arterial thrombosis in COVID-19.<br><br>METHODS: A scoping review of English-language studies indexed in PubMed/Medline, OVID, and Wiley Library was conducted from January 2020 to June 2024. Search terms related to COVID-19, thrombotic complications, pathophysiological mechanisms, and antithrombotic therapies were included. Clinical trials, cohort and retrospective observational studies, systematic reviews, meta-analyses, and case reports are included. Two reviewers independently screened titles, abstracts, and full texts for relevance and extracted data to map current evidence on venous and arterial thrombosis in COVID-19.<br><br>RESULTS: COVID-19-related coagulation problems can cause both venous and arterial thrombosis. Venous thromboembolism, which includes deep vein thrombosis and pulmonary embolism, occurs in about 4% to 15% of hospitalized patients and can increase to 30% in those in intensive care, even with standard prevention. Elevated D-dimer levels are strongly associated with a higher risk of clot formation. Arterial clots, like strokes or heart damage, are less common but generally more serious, caused by platelet activation, inflammation, and small vessel blockage rather than just slow blood flow in veins. Evidence indicates that low-molecular-weight heparin is the preferred anticoagulant because it reduces both inflammation and clotting. Therapeutic doses may be especially beneficial for high-risk patients, and continuing clot prevention after hospital discharge helps lower the risk of late clots without significantly increasing bleeding risk.<br><br>CONCLUSION: Recognition of COVID-19-associated coagulopathy underscores the necessity of early risk stratification and individualized anticoagulation to mitigate thrombotic events and improve outcomes. Extended post-discharge prophylaxis appears promising in reducing late thrombotic complications. Future research should aim to refine optimal anticoagulant regimens and determine ideal prophylaxis duration for COVID-19-related thrombosis to reduce morbidity and mortality rates.}, }

The outcomes were VTE and ATE, including deep vein thrombosis, pulmonary embolism, myocardial infarction, and stroke. The effect sizes were combined using a random-effects model with inverse variance weighting, and a 95% confidence interval was calculated through arcsine transformation. A total of 224 studies was included. The occurrence of VTE was 5.8% (95% CI, 5.0%-6.7%, I2 = 99.912%; 91 studies; 4,545,285 patients).

This meta-analysis synthesizes prospective cohort studies to estimate the prevalence of Long COVID symptoms and identify risk factors. Methods: We systematically searched PubMed for prospective cohort studies (2020-2025) on Long COVID, focusing on prevalence and risk factors. Studies with ≥100 participants and follow-up ≥3 months were included. Data were extracted on symptom prevalence (e.g., fatigue, dyspnoea) and risk factors (e.g., sex, hospitalization). Random-effects models were used to pool prevalence and odds ratios (OR). Risk of bias was assessed using the Newcastle-Ottawa Scale (NOS). Results: Fourteen prospective studies (n = 168,679) were included. Pooled prevalence of Long COVID was 18.0% (95% CI: 12.5-23.5%, I[2] = 9.8%) among survivors followed for ≥6 months. Fatigue (41.0%, 95% CI: 33.2-49.4%) and dyspnoea (22.5%, 95% CI: 15.6-29.8%) were the most common symptoms. Female sex (OR = 1.52, 95% CI: 1.25-1.92) and prior hospitalization (OR = 2.35, 95% CI: 1.98-2.90) were significant risk factors. High heterogeneity (I[2] > 90%) was noted. Conclusions: Long COVID affects over one-fifth of SARS-CoV-2 survivors, with fatigue and dyspnoea persisting in many. Female sex and severe acute infection increase risk.

Among the cardiac complications of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), atrial fibrillation (AF)-especially new-onset atrial fibrillation (NOAF)-has emerged as a major determinant of disease severity and prognosis. Clinical studies and meta-analyses show that 5-10% of hospitalized COVID-19 patients develop AF, with markedly higher rates in critically ill individuals. Both pre-existing and NOAF are independently associated with increased risks of intensive care admission, mechanical ventilation, thromboembolic events, and mortality. The underlying mechanisms involve a combination of cytokine-mediated inflammation, endothelial dysfunction, microvascular injury, and dysregulation of the renin-angiotensin-aldosterone system (RAAS). Viral downregulation of angiotensin-converting enzyme 2 (ACE2) receptors contributes to myocardial fibrosis, while hypoxia, oxidative stress, and autonomic imbalance further promote electrical remodeling and arrhythmogenesis. Post-infectious studies indicate that atrial structural changes and autonomic dysfunction may persist for months, predisposing survivors to recurrent arrhythmias. Technological advances in telecardiology and digital medicine have provided new tools for early detection and long-term monitoring. Wearable electroencephalography (ECG) devices, implantable loop recorders (ILRs), and artificial intelligence (AI)-based diagnostic algorithms enable continuous rhythm surveillance and individualized management, improving outcomes in post-COVID patients. This review summarizes current evidence on the epidemiology, pathophysiology, clinical implications, and monitoring strategies of AF in COVID-19. It underscores the importance of integrating telemedicine and AI-assisted diagnostics into cardiovascular care to mitigate the long-term arrhythmic and systemic consequences of SARS-CoV-2 infection.}, }

It possesses antimicrobial properties and is available in solution, dermal spray, and scar gel forms. Objectives/Methods: This review presents data from studies on the clinical use of HOCl in various specialties, including dermatology, surgery, dentistry, ophthalmology, and rhinology. Results: Due to its anti-inflammatory/antimicrobial/immunomodulatory and healing properties, HOCl is advantageous in treating various skin disorders: ulcus cruris (and wound care), diabetic ulcers, atopic dermatitis, seborrheic dermatitis, pruritus, acne vulgaris, etc. Also, the application of a HOCl spray/gel after surgical procedures may prevent infection, reduce inflammation, and accelerate healing. HOCl is also effective and safe for the prevention and treatment of hypertrophic and keloid scars. Growing evidence shows a broader role for HOCl in limiting cancer cell survival and slowing tumor growth. It is also important in treating various viral infections like SARS-CoV-2 (coronavirus), influenza, and herpes, thereby helping to prevent the spread of aerosols. In addition, since HOCl is an endogenous compound naturally present in mammals with a high safety profile, it may be an effective bacterial disinfectant in dental waterlines. In ophthalmology, adjuvant treatment with HOCl ophthalmic spray can reduce the duration of antibiotic/corticosteroid use, even in severe blepharitis. To fully harness the protective/therapeutic properties of HOCl, future advancements will rely on the development of new chemical compounds and sophisticated pharmaceutical formulations. Conclusions: The majority of clinical studies have confirmed that HOC1 is useful in therapy, although the results are not entirely consistent. Further research is essential to optimize HOCl dosing and to develop controlled-release systems aimed at maximizing its anti-inflammatory and photoprotective effects while minimizing tissue irritation and damage.}, }

The presence of SARS-CoV-2 in the oral cavity and periodontium raises questions about its potential impact on periodontal health. Methods: A comprehensive literature search was conducted in PubMed using terms related to LC (e.g., "long-COVID," "post-acute sequelae of SARS-CoV-2 infection," "PASC," "post-COVID-19," "long-haul COVID") and oral/periodontal diseases (e.g., "periodontal disease," "periodontitis," "gingiva," "oral disease," "dental"), filtered for English-language full-text articles published from 2019 to 2024. The search yielded 260 articles, which were supplemented with targeted searches on pathogenesis, immune mechanisms, microbiome alterations, and clinical outcomes, resulting in approximately 248 studies included in this review. Results: LC exhibits systemic immunoinflammatory dysregulation, including neutrophil activation, elevated pro-inflammatory cytokines, and complement activation, overlapping with mechanisms implicated in periodontitis. LC also leads to gastrointestinal and pulmonary dysbiosis, with potential effects on oral microbial communities. Gingival epithelium and periodontal ligament cells express ACE2, which is increased in periodontitis, facilitating viral entry. LC has been associated with reactivation of herpesviruses, such as Epstein-Barr virus, which are linked to autoimmune disorders and periodontitis. Conclusions: LC may act as a systemic risk factor for periodontitis. This review provides the theoretical foundation for the interactions between LC and oral health and highlights priorities for future epidemiologic and mechanistic research to better understand these relationships.}, }

This review aimed to synthesize global evidence on the cost-effectiveness of key COVID-19 control strategies, including vaccination, testing, and social distancing and to identify methodological, contextual, and equity-related determinants of their economic value. Methods: A narrative literature review was conducted using peer-reviewed studies published between January 2020 and September 2025 and indexed in PubMed, Scopus, and Web of Science. Eligible studies included economic evaluations and modeling analyses addressing COVID-19 interventions in healthcare, community, or educational settings. Data on costs, outcomes, and methodological features were extracted and synthesized descriptively. Results: Across 74 included studies, vaccination-particularly with messenger RNA (mRNA) platforms-emerged as the most cost-effective intervention across all settings, often cost-saving among high-risk populations. Combined or layered strategies integrating vaccination, testing, and selective social distancing consistently outperformed single interventions in both health and economic outcomes. Early and targeted implementation yielded the highest cost-effectiveness by preventing exponential transmission and healthcare overload. However, heterogeneity in modeling assumptions, analytic perspectives, and outcome measures limited comparability. Few studies applied extended or distributional cost-effectiveness frameworks to address equity, while indirect and long-term effects such as productivity losses and "long COVID" were frequently omitted. Conclusions: COVID-19 interventions are most efficient when early, targeted, and adaptive to local epidemiologic conditions. Integrating equity, methodological consistency, and broader societal impacts into future evaluations will strengthen evidence-based, economically sustainable pandemic preparedness and response strategies.}, }

Eight electronic databases were searched (MEDLINE, PsycINFO, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Social Sciences Citation Index (SSCI), Social Policy and Practice (SPP), Applied Social Sciences Index and Abstracts (ASSIA), MedRxiv and Research Square) for English language qualitative studies. Reference lists of relevant literature reviews and reference lists of articles were hand-searched for additional potentially relevant articles. Duplicates were removed, and articles were screened for titles and abstracts, followed by full-text screening. The Mixed Methods Appraisal Tool (MMAT) was used to assess the quality of the included studies (n = 70). Data were synthesised using thematic synthesis. Seven major and three minor themes were identified. The major themes related to (i) children and young people's experiences of COVID-19; (ii) exacerbated pre-existing disparities relating to income, employment and housing security, health insurance and immigration status; (iii) lack of knowledge and information about COVID-19 and COVID-19 misinformation; (iv) racial history of medicine and treatment of racialised populations; (v) contemporary experiences of racism; (vi) impact on physical and mental health and wellbeing; (vii) concerns about safety at work. Minor themes related to (a) experiences of intercommunity mutual aid; (b) adherence to preventative guidance/COVID-19 restrictions; (c) the role of faith.

A growing body of evidence suggests that viruses with dermatologic manifestations may play a significant role in the pathogenesis of neurologic disorders. Summary: Although individual viruses have been studied in isolation, the skin-brain axis in viral infections remains incompletely characterized. This review synthesizes existing knowledge and highlights gaps in understanding the mechanisms linking cutaneous viral infections to neurologic disease. We explore the principal mechanisms linking viral skin infections to central and peripheral nervous system damage, including direct neuroinvasion, immune-mediated injury, and vascular or endothelial dysfunction. Particular attention is given to herpesviruses, retroviruses, enteroviruses, and respiratory viruses, which have been associated with conditions such as dementia, multiple sclerosis, myelopathies, Guillain-Barré syndrome, and the post-acute neurologic sequelae of COVID-19. Furthermore, we discuss the role of neuroinflammation in viral-associated neurodegeneration and highlight emerging evidence supporting the recombinant zoster vaccine (Shingrix) as a potential modulator of neuroinflammatory processes and a protective factor against dementia. Conclusions: Cutaneous viral infections extend beyond local skin pathology, contributing to a broad spectrum of neurologic complications through intertwined infectious and inflammatory mechanisms. A clearer understanding of how peripheral viral activity shapes central nervous system vulnerability remains a major unmet need. A multidisciplinary approach integrating dermatologic and neurologic perspectives is essential for early recognition and prevention. While observational studies suggest that zoster vaccination may reduce viral reactivation and modulate neuroinflammatory pathways, definitive evidence of neuroprotection is still lacking. Future studies should clarify causal relationships, test mechanistic hypotheses regarding skin-brain immune crosstalk, and explore vaccine-mediated neuroprotection as a novel therapeutic strategy.}, }

Clinically, FM is measured indirectly as its derivative, soluble fibrin monomer complexes (SFMC), which is also often referred to as FM throughout the clinical literature. FM participates in a complex regulatory network modulating thrombin generation and fibrinolysis, interacting with platelet receptors, including integrin αIIbβ3 and GPVI, and engaging GPIb-vWF interactions. This comprehensive review examines FM's molecular mechanisms in haemostatic regulation and evaluates clinical evidence for FM as a biomarker. Particular focus is placed on FM's utility for risk stratification across thrombotic conditions, including disseminated intravascular coagulation, venous thromboembolism, ischemic stroke, myocardial infarction, and COVID-19-associated coagulopathy. Current challenges, including assay standardization and universal cut-off values, are discussed. By synthesizing mechanistic insights with clinical data, this integrated perspective may accelerate the translation of FM biology into improved risk assessment tools and novel therapeutic strategies.}, }

During viral infections, PTMs are shown to play a multitude of roles in viral replication, host interaction, and immune evasion. Thus, these modifications can influence infectivity, with direct impact on the anti-viral host immune responses and potentially viral adaptation across species. This field is still scarcely explored, whilst understanding PTMs is not only important to advance the knowledge of virus pathology but also potentially to provide insights for vaccine development. In this review, we attempt to summarize the latest findings mainly published over the last 10 years, focusing on the roles of PTMs involved in virus infection and anti-viral immune responses, in the context of relevant human respiratory infections: influenza A virus (IAV), respiratory syncytial virus (RSV), and SARS-CoV-2. We decided to concentrate on these three viruses because they currently represent a global health problem due to recurrent outbreaks and pandemic potential. A deeper characterization of the PTMs may help in understanding virus-host interaction with possible implications on curative strategies. Further, we will report on cutting-edge technologies to study in vitro virus infection in different cellular-based systems. In particular, we describe and discuss the application of 2D and 3D lung organoid cell-culture systems as in vitro models to mimic respiratory environments and to study the PTMs in a controlled setting. Finally, we will discuss the importance of PTMs in the context of next-generation vaccine design, especially for their potential role to offer effective protection against respiratory viruses.}, }

Currently, the design and preparation of nucleic acid delivering systems face many scientific problems and technical challenges. Breaking through the technical bottlenecks in intraneous delivery of nucleic acid molecules is anticipated to open a new era of efficient, precise and safe nucleic acid drugs.

Diabetes remains one of healthcare's toughest challenges, demanding round-the-clock monitoring and treatments that adapt to each patient's needs.

Meanwhile, AI-through machine learning (ML) and deep learning (DL)-brings fresh capabilities for catching diabetes early, assessing patient risk, and spotting complications like eye and nerve damage before they become serious. We examined recent research on these technologies, particularly their roles in predicting who might develop diabetes, using Natural Language Processing (NLP) to decode messy patient records, and supporting doctors through clinical decision support systems (CDSS). Our findings reveal that telemedicine works-it helps patients control their blood sugar better and keeps them satisfied with their care. However, not everyone has equal access to technology, and some healthcare providers remain skeptical. AI diagnostic tools, especially for eye screening, now match human doctors in accuracy. Though merging these technologies could revolutionize personalized diabetes care, we first need to tackle real-world obstacles: ensuring fair access for all patients, protecting sensitive health data, and making different systems work together seamlessly.}, }

The COVID-19 pandemic disrupted hRSV transmission due to non-pharmaceutical interventions (NPI), resulting in atypical circulation patterns, earlier seasonal peaks, and increased post-pandemic prevalence. Two key factors are proposed to underlie these changes: a reduced specific immune response due to decreased viral exposure and the emergence of novel hRSV variants. These factors contributed to a larger cohort of immunologically naïve children and lower levels of maternally derived antibodies, increasing susceptibility to severe hRSV disease, particularly in infants and children. Additionally, adults experienced waning immunity following prolonged periods of limited hRSV circulation. The post-pandemic resurgence was accompanied by the emergence of novel hRSV variants with altered transmissibility and virulence, such as GB5.0.6a in Europe and B.D.E.1 in China. These variants may reflect mutations driven by the reduced immunity, though further research is needed to assess their pathogenicity. Understanding the interplay between the reduced immunity due to NPI and virological factors is essential for addressing hRSV epidemiology. Enhanced molecular surveillance and immunological monitoring are crucial for guiding vaccination strategies and protecting vulnerable populations against future hRSV outbreaks.}, }

Data extraction captured study design, participant population, and factors influencing trial enrolment. Findings were thematically analysed, with subgroup synthesis for underserved populations, including pregnant individuals, parents, ethnic minority groups, and LGBTQ+ communities.<br><br>RESULTS: Analysis of the 145 included studies identified five themes for enablers and four themes for barriers. Safety concerns were the most frequent deterrent, particularly for proxy decision-makers such as parents and pregnant participants. Institutional mistrust and misinformation were consistent barriers, with the COVID-19 pandemic heightening distrust of governments and pharmaceutical companies and amplifying misinformation through social media. Additional barriers included sociocultural expectations and logistical burdens, particularly in low-resource settings. Enrolment was enabled by altruistic motivations, perceived personal or community benefit, transparent safety communication, logistical ease, and community engagement. Community-led engagement, culturally concordant staff, and proportionate incentives were consistently associated with improved enrolment.<br><br>CONCLUSIONS: Vaccine trial participation is shaped by a dynamic risk-benefit calculus that manifests differently across populations. Addressing inequities requires sustained community partnerships, culturally competent trial design, proportionate material support, and proactive communication strategies to counter misinformation. These findings provide actionable guidance for designing more inclusive vaccine trials.}, }

Global estimates indicate that the incidence of ILDs has risen by over 50% in the recent years. In India, epidemiological data remain limited and inconsistent due to heterogeneity in diagnostic criteria and regional disparities, impeding accurate burden estimation and policy prioritization.<br><br>MAIN TEXT: Among ILDs, progressive fibrotic forms, idiopathic pulmonary fibrosis (IPF) in particular, cause substantial morbidity and mortality. Many ILDs progress to irreversible fibrosis, leading to declining lung function, impaired quality of life and shortened survival. Timely and precise diagnosis of progressive fibrotic (PF)-ILDs is imperative to facilitate early therapeutic intervention and potentially slow down fibrotic progression. Diagnostic evaluation necessitates high-resolution computed tomography, histopathological examination and multidisciplinary team consensus, all of which&#xa0;are often unavailable or prohibitively expensive outside tertiary care centres in India. Therapeutic options are confined primarily to two antifibrotic agents approved for IPF, which modestly attenuate disease progression but do not significantly improve survival in patients. Access to these therapies is limited by cost, lack of proper insurance coverage and non-uniform healthcare infrastructure. Clinical presentation is often delayed owing to low disease awareness and referral gaps. Although, pulmonary fibrosis following novel coronavirus disease 2019 has attracted recent attention, it constitutes a minor fraction of the PF-ILD burden. Despite the high morbidity and mortality associated with PF-ILDs, these conditions are inadequately represented in India's health policy instruments, research agendas and funding priorities.<br><br>CONCLUSIONS: The burden of PF-ILDs in India demands an urgent policy response, which involves integrating ILDs into national non-communicable disease frameworks, expanding diagnostic capacity in secondary care, improving affordability and access to antifibrotic drugs and supporting multicentre registries for surveillance and research. Addressing these gaps could reduce disease impact domestically and provide a model for other low- and middle-income countries confronting similar challenges in tackling fibrotic lung diseases.}, }

Nevertheless, many challenges remain to be overcome, including immunogenicity and toxicities, excessive liver accumulation, limited endosomal escape ability, low tissue bioavailability, poor mucosal immunity, and the need for cold chain storage. In recent years, extracellular vesicles (EVs) have emerged as an attractive mRNA delivery platform due to their favorable properties, such as low immunogenicity, natural capability to deliver RNAs, intrinsic targeting capacity, and the ability to negotiate with physiological barriers.

Post-translational modifications, especially phosphorylation, are pivotal in the lifecycle of these viruses. Phosphorylation affects key processes such as viral replication, transcription, assembly, and release, thereby influencing their propagation in host cells. Viral infection can also trigger kinase-associated pathways within host cells, activating host cell phosphatases and related signaling cascades. This results in alterations to host phosphorylation states, aggravating cellular pathology and facilitating viral proliferation.

The expression and secretion of PRL are influenced by several factors such as suckling, thyrotropin-releasing hormone (TRH), cytokines, dopamine, estrogen, and vasoactive intestinal polypeptide. It operates through a complex receptor, which is expressed in mammary gland cells, pancreatic beta cells, adipocytes, and immune cells. PRL is essential for various physiological functions, in particular milk production, breast development, metabolism, and immune regulation. Serum PRL levels fluctuate daily and can be affected by exercise, diet, and stress. Hyperprolactinemia is linked to autoimmune diseases and viral infections. In viral infections such as HIV, HCMV, HCV, and COVID-19, PRL levels are often increased, which may influence the immune responses. PRL can modulate the activity of various immune cells, including T cells, B cells, natural killer cells, and macrophages, mounting an effective immune response against viral infections. Moreover, PRL influences the production of cytokines that mediate and regulate immunity and inflammation. PRL stimulates B cells to produce antivirus antibodies that are essential for neutralizing viruses and preventing their spread within the body. PRL levels, varying by sex and life stage, may affect immune responses and susceptibility to viral infections. Moreover, overexpression of PRL was indicated in various autoimmune diseases. Overall, PRL is a complex hormone with significant implications for endocrine function, immune regulation, and immune responses to viral infections, highlighting the need for further research into its diverse roles in health and disease.

Infections of the human reproductive system and associated reproductive disorders pose a significant global public health challenge, characterized by diverse pathogens and complex pathogenic mechanisms. Recent research has revealed that ferroptosis plays a critical role in the pathological processes of many of these infections. This review systematically elaborates on the central mechanistic role of ferroptosis in various pathologies of the reproductive system. These include CD4[+] T cell depletion and immunological non-response in Human Immunodeficiency Virus (HIV) infection, the development of Human Papillomavirus (HPV)-associated cervical cancer, Staphylococcus aureus-induced endometritis and mastitis, as well as male infertility, pre-eclampsia, and ovarian cancer linked to Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection. Despite the diversity of the pathogens, they can all trigger ferroptosis through common mechanisms, such as disrupting the Nrf2/GPX4 antioxidant axis, impairing the System Xc[-]-GSH-GPX4 pathway, and inducing dysregulation of iron metabolism. Furthermore, ferroptosis interacts intricately with pyroptosis and apoptosis, forming a complex network that collectively regulates the outcome of infections and the extent of tissue damage. Notably, ferroptosis plays a context-dependent dual role in various reproductive system infections. During the initial phases of infection, it exerts a protective effect by eliminating pathogens and curbing infection progression. In contrast, during advanced or chronic stages, ferroptosis exacerbates tissue injury and promotes disease pathogenesis. The ferroptosis pathway holds great therapeutic promise, either through inhibitors that safeguard host cells or inducers that eradicate drug-resistant bacteria by triggering a "ferroptosis-like" state. Nevertheless, challenges remain for clinical translation, as the ferroptosis network is incompletely understood, and the tissue selectivity and long-term safety of targeted drugs are unverified. Future studies must elucidate host-pathogen interactions to develop precise targeted therapies.}, }

Controlled human infection models (CHIMs) using attenuated viral strains may offer an efficient and safe way to do this.<br><br>OBJECTIVE: Our aim was to systematically examine the literature for attenuated, but replication competent, strains of Coalition for Epidemic Preparedness Innovations (CEPI) identified priority pathogens (Ebola, Lassa virus, Nipah virus, Rift Valley fever virus, chikungunya virus and Middle East respiratory syndrome-related coronavirus) that have been administered to humans.<br><br>DESIGN: A comprehensive literature search of multiple databases was performed by an information specialist. All search results were screened by two authors against inclusion/exclusion criteria from a pre-specified protocol. The primary outcome was confirmation that the administered viral strain could subsequently be recovered from participants. The secondary outcome was attenuated virus safety.<br><br>RESULTS: Our searches yielded 13078 results and 5998 articles remained for screening after removing duplicates and animal studies. Subsequently, 351 articles were selected for full text review and nine were included for data extraction. Four distinct attenuated strains were identified across two priority pathogens - TSI-GSD-218 and VLA1553 for chikungunya virus and MP-12 and hRVFV-4s for Rift Valley Fever virus. Attenuated virus was recovered for each strain except hRVFV-4s. There were no major safety concerns for these identified strains in Phase 1-3 studies.<br><br>CONCLUSIONS: We have identified three attenuated viral strains that may be amenable to development into novel CHIMs for two priority pathogens. Of these, VLA1553 for chikungunya is a licenced and commercially available vaccine product suitable for use in CHIM. There is a research gap for the creation of new attenuated mutants that could be utilised in CHIM for other priority pathogens.}, }

Two reviewers independently selected studies, extracted data, and assessed risk of bias (Cochrane RoB 2). A narrative synthesis was performed due to substantial heterogeneity across studies.<br><br>RESULTS: We included 48 RCTs. DB protocols were highly heterogeneous, with parameters varying widely in breathing frequency (2-10 breaths/min), session duration (3-45&#x202f;min), and total duration (single session to 12 weeks). Methodological quality was a significant concern (only 2.12&#x202f;% of outcomes low risk of bias). Consistent benefits were found for gastroesophageal reflux disease (GERD) (including reduced medication use), anxiety, post-COVID-19 syndrome, and gestational diabetes). In healthy adults, DB showed acute cardiovascular benefits. However, evidence was inconsistent for chronic obstructive pulmonary disease, and DB was less effective than standard care after cardiac surgery. Safety was underreported (18.75&#x202f;% of studies), but no serious adverse events were noted.<br><br>CONCLUSIONS: DB is a promising complementary therapy for specific conditions, including GERD, but the evidence base is constrained by methodologically weak and heterogeneous primary studies. Future research requires rigorous, standardized trial designs to establish its clinical value. Despite these limitations, DB is a low-cost, accessible, and apparently safe intervention for select conditions.}, }

Age-related dysbiosis, with imbalance between symbionts and pathobionts, can in fact fuel chronic inflammation (inflammaging) and promote frailty. In older individuals, GM composition is characterized by marked inter-individual variability and consistently influenced by environmental exposures. Studies conducted in animals and closed human communities suggest that social contacts are associated with horizontal transmission of commensal bacteria, enhancing biodiversity and preventing dysbiosis. Recent studies also suggest transmission of intestinal commensal bacteria from animals to humans sharing the same household. Bacterial populations residing on environmental surfaces may also have an influence on GM composition. In this framework, impoverishment of social relationships in older individuals may not be only associated with cognitive and emotional disengagement, but also with unfavorable changes in GM composition, driven by isolation and top-down neuromodulation of intestinal function. In fact, studies conducted during forced social distancing in the COVID-19 pandemic suggest GM changes pointing towards dysbiosis. Therefore, the detrimental consequences of social isolation for health outcomes of older individuals, including frailty progression towards disability, could be at least partly mediated by GM dysbiosis. Conversely, interventions aimed at restoring sociality, including animal-assisted activities, could expose older individuals to a range of novel bacterial species helping to counteract GM dysbiosis. This perspective article critically discusses the concept of social microbiome, its possible relevance for maintenance of good health in human beings, and its implications for the care of older patients.}, }

A scoping review was conducted as per the updated Preferred Reporting Items for Systematic Reviews and Meta-analyses extension for Scoping Reviews (PRISMA-ScR) checklist. Using the PCC (Population, Concept, and Context) framework, search keywords and search strategies were developed. Electronic databases were searched using specific search terms and the last search date noted as February 8, 2025. A thematic content analysis was carried out to identify the themes and subthemes by a deductive approach. Fourteen studies were included as the potential sources of evidence in this review. The study population included 493,819 adolescents from Australia, Hong Kong, Italy, Poland, Saudi Arabia, and the USA. The themes identified were inequity, attitude and behaviour, knowledge and communication, and engagement and influence. The COVID-19 pandemic generated a negative parental attitude towards HPV vaccines for a brief period. The adolescent HPV vaccine acceptance mainly depended on strong parental support and appropriate access to healthcare professionals and vaccination services. Travel restrictions, lockdowns, school closures, and social distancing contributed to significant HPV vaccine hesitancy in high income countries.}, }

Azole resistance is widespread in several clades, whereas resistance to amphotericin B and echinocandins is increasingly reported, particularly in high-endemic settings.

However, its epidemiological profile has shifted in recent years, with a rising incidence among critically ill patients in intensive care units (ICUs), many of whom lack classical risk factors. This change is driven by increased use of corticosteroids and immunomodulatory therapies, the growing prevalence of chronic lung disease, and severe viral pneumonias such as influenza and COVID-19. In these patients, airway epithelial injury, immune dysregulation, and mechanical ventilation facilitate fungal invasion even in the absence of profound immunosuppression. Corticosteroids play a central role in IPA pathogenesis. While they limit hyperinflammation, they simultaneously impair fungal clearance by suppressing NF-κB signaling, downregulating TNF-α production, and promoting IL-10 secretion, resulting in a Th2-skewed immune profile. Neutrophil recruitment persists but becomes dysregulated, contributing to tissue injury rather than effective pathogen elimination. Corticosteroids may also directly enhance Aspergillus growth, further compounding risk. Diagnosis of IPA in ICU patients remain challenging because radiological hallmarks such as the halo sign are uncommon, and distinguishing colonization from invasive disease is difficult. Serum and bronchoalveolar lavage galactomannan, β-D-glucan assays, and PCR can improve early detection, but no single test is definitive in this heterogeneous population. As much as possible, high-quality lower respiratory tract samples should be obtained. Furthermore, effective treatment requires not only timely diagnosis, but also careful selection of antifungal taking into consideration pharmacologic challenges of ICU patients and pharmacodynamics of antifungals. Recognition of high-risk patients such as those receiving corticosteroids, those with chronic lung disease, severe viral pneumonia, or requiring invasive ventilation is critical to improve outcomes. Mortality in this group can exceed that of neutropenic patients, underscoring the need for heightened clinical suspicion and timely antifungal therapy. A deeper understanding of the immunopathogenesis of IPA in non-neutropenic patients, particularly the dual effects of corticosteroids on inflammation and host defense, may inform risk stratification and guide earlier intervention. Enhanced surveillance, prompt diagnostic workup, and judicious use of immunomodulatory therapy represent key strategies to mitigate the rising burden of this devastating infection in ICU settings.}, }

The updated recommendations prioritize vaccination with LP.8.1-adapted vaccines for high-risk groups-adults aged 65 years and older, individuals aged 6 months and older at increased risk for severe disease, and residents of facilities vulnerable to infection-while vaccination remains available for all individuals aged 6 months and older. A single-dose strategy is generally recommended, although older adults and immunocompromised individuals may consider an additional dose at 6-month intervals in consultation with healthcare professionals. These updates aim to refine Korea's COVID-19 vaccination strategy and sustain protection in high-risk populations, with recommendations remaining subject to revision as new evidence and epidemiological conditions evolve.}, }

In the context of patients experiencing various physical and mental symptoms that persist long after the acute phase of coronavirus disease 2019 (COVID-19) infection, the diagnosis and management of PASC has emerged as a novel public health challenge. These guidelines are intended to provide standardized diagnostic and management recommendations applicable to the Korean healthcare setting and were developed through a comprehensive review of existing guidelines from organizations such as the World Health Organization, the United States National Institutes of Health, the United Kingdom National Institute for Health and Care Excellence, and the European Society of Clinical Microbiology and Infectious Diseases, along with the latest meta-analyses and Korean cohort studies. PASC is defined as the persistent presence of symptoms and signs lasting more than 3 months after COVID-19 diagnosis for which the symptoms cannot be explained by alternative diagnoses. The revised guidelines emphasize the importance of integrated management for patients with PASC, including a multidisciplinary approach considering risk groups, symptom-specific assessment, and rehabilitation and psychological interventions, based on a total of 32 key questions. This revision reflects rapidly evolving research trends regarding the long-term effects of COVID-19 and is expected to serve as an evidence-based standard guideline for future patient care, clinical research, and health policy development in Korea.}, }

Long COVID is a complex, multisystem disorder that can affect nearly every organ system and is strongly linked with the incidence of diabetes and other chronic conditions. Increasing evidence also connects persistent SARS-CoV-2 infection with the development of new-onset diabetes and other metabolic disorders. In this review, we assess the current evidence and discuss the incidence of new-onset diabetes, along with the pathobiological mechanisms by which SARS-CoV-2 may contribute to the progression of both new-onset type 1 and type 2 diabetes mellitus (T1DM and T2DM). We summarize the latest understanding of the molecular and cellular mechanisms underlying SARS-CoV-2-associated new-onset diabetes. Potential mechanisms include direct damage to pancreatic β-cells, inflammation, insulin resistance, and autoimmune responses. Dysregulation of the ACE2/renin-angiotensin system (RAS) pathway has been linked to multiple inter-organ pathologies, and increased inflammatory cytokines together with dysregulation of interferon regulatory factors (IRFs)-such as overexpression of IRF1-appear to represent key mechanistic links to widespread tissue damage and metabolic alterations. Moreover, the presence of viral RNA or viral RNA fragments may directly damage pancreatic islets, contributing to insulin resistance and β-cell dysfunction that, in turn, may promote the development of new-onset diabetes. In light of these findings, this review further examines evidence supporting the persistence of SARS-CoV-2 RNA in PASC reservoir tissues, including the pancreas, and its potential association with the development of new-onset diabetes mellitus.}, }

Eligible studies included randomized controlled trials (RCTs), cohort studies, case-control studies, self-controlled case series, and pharmacovigilance database analyses reporting myocarditis or GBS outcomes in adolescents receiving BNT162b2 or mRNA-1273. The search was conducted in June 2025, and all published studies were included. Risk of bias was assessed using the Cochrane RoB-2 tool, Newcastle-Ottawa Scale, or adapted criteria for pharmacovigilance studies. Effect measures were expressed as incidence rate or incidence rate ratios (IRRs) with 95% confidence intervals (CIs). Meta-analyses were conducted using random-effects models. Ten studies met the inclusion criteria. Myocarditis incidence was elevated in adolescent and young adult males, particularly after the second dose. Pooled analyses indicated a higher risk with mRNA-1273 compared to BNT162b2 (pooled IRR ≈ 3.9), although heterogeneity was very high (I[2] > 95%). For GBS, global pharmacovigilance data suggested only a modest association with mRNA vaccines (ROR 9.66), substantially weaker than for adenoviral vector or influenza vaccines. COVID-19 mRNA vaccination in adolescents is associated with a small but measurable increased risk of myocarditis, particularly in males, after the second dose, with a higher incidence following mRNA-1273. No consistent evidence of increased GBS risk was observed. Absolute risks remain low, and outcomes are generally favorable compared to SARS-CoV-2 infection. Continued surveillance and long-term follow-up are warranted.}, }

Ensuring equitable healthcare access for older adults with NCDs is a pressing challenge. Mobile health clinics and telehealth services have emerged as key strategies to reach underserved elderly populations and maintain continuity of NCD care in remote or resource-limited settings.<br><br>OBJECTIVE: To examine current mobile clinic initiatives and telehealth outreach in Thailand focused on elderly care and NCD management, and to evaluate their impact on healthcare access and outcomes for older adults.<br><br>METHODS: We conducted a narrative review of published literature, policy reports, and program descriptions on mobile health clinics and telehealth interventions in Thailand, with emphasis on applications for older adults and chronic disease care (eg, diabetes, hypertension). A comprehensive search (2010-2025) of PubMed, Google Scholar, and Thai government/organization websites identified relevant sources. Data on intervention models, settings, target populations, and reported outcomes were extracted. In total, 15 key publications and reports were reviewed, from which 8 major mobile clinic or telehealth initiatives were identified.<br><br>RESULTS: Mobile health clinics have expanded primary care access for vulnerable elderly in both urban and rural areas. The Thai Red Cross Society's mobile clinic serves remote mountainous communities and provides primary care, NCD screenings, vaccinations, and medications to about 5,000 underserved people annually. Past mobile outreach programs have uncovered many untreated cases-in one survey, 58% of hypertensive and 75% of diabetic elderly were first diagnosed via a mobile unit. Telehealth services have likewise grown substantially. During the COVID-19 pandemic, telemedicine was rapidly adopted for routine consultations and chronic disease follow-ups. The National Health Security Office (NHSO) introduced a nationwide telemedicine service under the Universal Coverage Scheme, enabling remote consultations and medication deliveries for stable chronic NCD patients, ensuring continuity of care during lockdowns. Numerous telehealth applications emerged (public and private); for example, smartphone apps like MorDee ("Good Doctor") gained wide usage in Thailand. In an urban pilot "Dusit Telemedicine" model, integrating community clinics with a tertiary hospital, over 300 elderly patients received teleconsultations, reducing overcrowding. An acceptance study in this Bangkok pilot found older generations significantly less likely to adopt telemedicine than younger people - perceived ease of use was a strong predictor of acceptance (adjusted OR 3.95 for usability). Community-based telehealth pilots in rural areas, such as a Chiang Mai program using Community Health Leaders, demonstrated high satisfaction (&#x2265;90%) and successful NCD risk screenings, but also highlighted the need for training and support for both health workers and patients.<br><br>CONCLUSION: Mobile clinics and telehealth are complementary strategies for enhancing healthcare delivery to elderly Thais with NCDs. Mobile clinics physically bring essential services to those unable to travel, while telehealth connects patients to providers for continuous care and monitoring. The Thai experience illustrates that integrating these innovations into primary healthcare systems can enhance equity of care for aging populations. Continued support, digital literacy training for seniors, and policy integration of telehealth into the health system are recommended to ensure healthy aging under universal health coverage.}, }

Thrombospondin-1 (Thbs1/TSP1), a multifunctional glycoprotein significantly upregulated during inflammation, exemplifies a dualistic regulator with context-dependent roles. Through modulation of cytokine networks and inflammatory cell activity (notably macrophages), Thbs1 critically governs inflammatory responses. Acute respiratory distress syndrome (ARDS), a life-threatening condition fueled by systemic inflammation secondary to infection or trauma, presents complex pathophysiology requiring elucidation. COVID-19 research highlights elevated Thbs1 expression in severe patients, where it demonstrates protective effects against pulmonary damage primarily via extracellular matrix protection, inhibition of neutrophil serine proteases, and TGF-β-dependent repair pathways. However, paradoxical evidence indicates that dysregulated Thbs1 can also contribute to ARDS pathogenesis, potentially by amplifying inflammation, promoting thromboinflammation, or driving fibrosis. Mechanistic insights reveal Thbs1's influence on ARDS progression through ECM remodeling, serine protease inhibition, and TGF-β activation. While significant progress has been made in understanding Thbs1 signaling, the precise mechanisms dictating its context-dependent switch between protective and pathogenic functions in inflammatory pathways remain a critical area for future investigation.}, }

Its classic clinical features include prolonged fever, bilateral conjunctival injection, changes in the lips and oral cavity, cervical lymphadenopathy, rash, and extremity changes. Acute jaundice and liver dysfunction are atypical manifestations of KD. Cases in which jaundice is the initial presenting symptom-especially when accompanied by Torque Teno Virus (TTV) infection-are rarely reported.<br><br>CASE PRESENTATION: We describe a 17-month-old boy diagnosed with incomplete Kawasaki disease (IKD), who initially presented with persistent fever, jaundice, and elevated liver enzymes. At disease onset, characteristic mucocutaneous signs of KD were absent. As the illness progressed, the patient developed dorsal foot edema, erythematous lips, and cervical lymphadenopathy. On the ninth day of illness, echocardiography revealed dilation of the left coronary artery, confirming a retrospective diagnosis of IKD. Additionally, high-throughput sequencing of peripheral blood identified TTV type 28. The patient was treated with intravenous immunoglobulin, methylprednisolone, and hepatoprotective agents. Following treatment, his fever resolved, jaundice subsided, liver function normalized, and coronary artery dimensions gradually returned to within the normal range.<br><br>CONCLUSIONS: This case highlights an atypical presentation of IKD, characterized by early-onset jaundice and later development of coronary artery dilation, in a patient also infected with TTV. To our knowledge, this is the first reported case of IKD associated with acute icteric hepatitis and TTV infection. This case may inform clinical evaluation in similar presentations and contribute to future research on the etiology of KD.}, }

The COVID-19 pandemic has accelerated the adoption of IoT devices, particularly wearable medical devices, which enable real-time health monitoring and advanced remote health management. Globally, the increased adoption of IoT in health care has improved efficiency, enhanced patient care, and generated substantial economic value.<br><br>OBJECTIVE: This review aims to conduct a comprehensive meta- and weight analysis of quantitative studies to identify the most influential predictors and theoretical frameworks explaining the adoption of IoT in health care.<br><br>METHODS: We searched databases, including Web of Science and PubMed, for quantitative studies on IoT health care adoption, with the last search conducted in early July 2025. Inclusion criteria comprised peer-reviewed articles written in English that employed a quantitative approach to IoT health care technology adoption. Studies were excluded if they did not report the significance of relationships, involved technologies without IoT features or were outside the scope, or examined target variables irrelevant to the analysis. The weight analysis identified the pathways with the most significant effects. A meta-analysis using a random-effects model was conducted to estimate combined effect sizes and their statistical significance. The results from both methods were then integrated to visualize the most frequently used theoretical frameworks. Risk of bias and heterogeneity were assessed using a funnel plot, Egger regression test, the I2 statistic, and subgroup analysis, which indicated no strong evidence of publication bias but revealed a high level of heterogeneity.<br><br>RESULTS: Analysis of 115 datasets from 109 papers identified the Technology Acceptance Model and the Unified Theory of Acceptance and Use of Technology (UTAUT) as the primary frameworks for explaining IoT adoption in health care. Incorporating context-specific variables-such as health consciousness, innovativeness, and trust-into these traditional technology acceptance frameworks enhances the understanding of IoT adoption. Although high heterogeneity suggests a need to refine theoretical models to account for regional contexts, universal adoption drivers such as performance expectancy and effort expectancy remain consistent.<br><br>CONCLUSIONS: Behavioral intention is the most frequently studied variable in IoT health care adoption, whereas attitude, performance expectancy, effort expectancy, and task-technology fit remain underexplored. While adoption theories from the information systems field, such as the TAM, are predominantly used, integrating context-specific constructs and theories-such as trust and innovativeness-can provide deeper insights into IoT adoption in health care. The strongest and most consistent predictors of behavioral intention were attitude, performance expectancy, habit, self-efficacy, functional congruence, and benefits. Additionally, social influence, facilitating conditions, trust, and aesthetic appeal demonstrated promising or strong effects. By contrast, variables such as privacy and security, barriers, vulnerability, severity, compatibility, financial cost, health, and technology anxiety were generally inconsistent or not statistically significant.}, }

Given the growing prevalence of long-COVID worldwide, understanding how SARS-CoV-2 affects hippocampal structure and function has become an urgent scientific and clinical priority. The hippocampus-crucial for memory, emotional regulation, and executive functioning-is especially susceptible to viral-driven neuroinflammatory cascades. SARS-CoV-2 triggers astrocyte and microglia activation, disrupts blood-brain barrier integrity, and induces cytokine-mediated neurotoxicity, ultimately impairing neuroplasticity and neurogenesis. These mechanisms converge to produce cognitive and affective disturbances-most notably fatigue, apathy, low mood, and executive dysfunction-that typify dysexecutive syndrome in long-COVID. This review synthesizes current evidence from clinical and experimental studies, integrating findings on viral neurotropism, hippocampal hypometabolism, and astrocyte-mediated neurodegeneration. Distinctions between depressive symptoms driven by neuroinflammation and classical depressive disorders are clarified to improve diagnostic accuracy and guide personalized treatment. Emerging data on the neuroprotective role of COVID-19 vaccination-particularly its capacity to modulate microglial activation and support hippocampal neurogenesis-are also examined. Overall, the findings underscore the need for targeted therapeutic strategies aimed at modulating neuroinflammation and supporting hippocampal plasticity, including cognitive rehabilitation approaches. Longitudinal studies are essential to elucidate the enduring impact of SARS-CoV-2 on hippocampal function and to inform effective clinical interventions.}, }

We aim to cover the immune system, the cardiopulmonary system, the musculoskeletal system, and the central nervous system (brain function), particularly among older adults, college students, and individuals with post-acute sequelae of COVID-19 (Long-COVID). The COVID-19 pandemic has given us many lessons, learned from the death of six million lives and tremendous disturbance to human life. First, we need to continue to investigate cellular and molecular mechanisms that mediate various organistic failures resulting from the viral infection. Such investigations are the only way to completely understand the etiology of the diseases and to develop new drugs and vaccines. The molecular pathways that transmit the signals of viral infection to each organ system are different requiring both basic and clinical research. Available evidence suggests that mitochondrial dysfunction, reduced microcirculation and latent immune activation play a major role, eventually impairing cardiovascular tolerance and peripheral bioenergetics. Second, the COVID-19 pandemic has manifested major disturbances to human lifestyles with reduced PA and exercise standing out as a major factor. Conversely, physical inactivity due to social confinement and mental/psychological stresses has been clearly linked to intensified pathogenic symptoms and amplification of adverse effects on multiple physiological systems. If not intervened, this interaction can lead to Long-COVID, a dangerous futile circle to cause systemic failure. Finally, the COVID-19 pandemic has exerted differential impacts on different populations. Thus, the strategy to develop and conduct to cope with the negativity of pandemic needs to be specific, flexible and tailored to fit different patient populations.}, }

To characterize the nature and scope of these reports, a systematic literature search from January 2020 to October 2025 was conducted based on specified eligibility criteria. A total of 69 publications met inclusion criteria: 66 article-level reports describing 333 patients across 27 countries, 2 retrospective population-level investigations (Italy: ~300,000 cohort, and Korea: ~8.4 million cohort) quantified cancer incidence and mortality trends among vaccinated populations, and one longitudinal analysis of ~1.3 million US miliary service members spanning the pre-pandemic through post-pandemic periods. Most of the studies documented hematologic malignancies (non-Hodgkin's lymphomas, cutaneous lymphomas, leukemias), solid tumors (breast, lung, melanoma, sarcoma, pancreatic cancer, and glioblastoma), and virus-associated cancers (Kaposi and Merkel cell carcinoma). Across reports, several recurrent themes emerged: (1) unusually rapid progression, recurrence, or reactivation of preexisting indolent or controlled disease, (2) atypical or localized histopathologic findings, including involvement of vaccine injection sites or regional lymph nodes, and (3) proposed immunologic links between acute infection or vaccination and tumor dormancy, immune escape, or microenvironmental shifts. The predominance of case-level observations and early population-level data demonstrates an early phase of potential safety-signal detection. These findings underscore the need for rigorous epidemiologic, longitudinal, clinical, histopathological, forensic, and mechanistic studies to assess whether and under what conditions COVID-19 vaccination or infection may be linked with cancer.}, }

This scoping review examined the health needs and key determinants affecting migrant populations in transit, specifically pregnant women and children travelling from their countries of origin to their intended destination countries, with the aim of identifying major barriers and proposing strategies for improved health outcomes. We screened 1202 sources of evidence using five databases (PubMed, Scopus, Europe PMC, CINAHL, and Medline) as well as grey literature. Seven studies met the inclusion criteria. Data were drawn from peer-reviewed literature, charted using a standardized framework, and analysed thematically. Key barriers included financial constraints, language obstacles, and limited access to healthcare services. Although humanitarian organizations offered some support, significant unmet needs remain, including exposure to transactional sex, absence of respectful maternity care, and restricted access to essential health services. These challenges are exacerbated in conflict and crisis settings. The review underscores the importance of addressing key determinants, including location, language, financial capacity, and community support, to improve health outcomes for pregnant women and children under five on the move.

Over the past two decades, researches have demonstrated that white adipose tissue (WAT) browning is an effective strategy to enhance energy expenditure. However, a growing body of evidence indicates that the browning process frequently occurs in a variety of chronic disease states, though its pathophysiological significance remains unclear. This review summarized evidence of pathological browning observed in human diseases and animal models, including breast cancer, colorectal cancer (CRC), clear cell renal cell carcinoma (ccRCC), kidney health, burn injury, atherosclerotic, SARS-CoV-2 and sepsis. Despite distinct pathological contexts, adipose tissue browning is consistently observed. This suggests that browning may not simply serve its classical metabolically protective role, but instead reflect an atypical response to pathological stress. It is currently unclear whether this is a compensatory mechanism by the organism in a diseased state or merely a byproduct of the disease process. Whether this response is adaptive or a cause of disease progression remains unresolved. Future research should therefore focus on identifying the triggers and functional outcomes of pathological browning to better understand adipocyte plasticity and its role in disease progression.}, }

Here, we report a case of AKI caused by osmotic nephropathy in a patient with underlying CKD following the initiation of an SGLT2 inhibitor. We also review previously reported cases of SGLT2 inhibitor-associated osmotic nephropathy. A 71-year-old man with type 2 diabetes and CKD developed oliguric AKI, with his serum creatinine level increasing from 2.0 to 8.3 mg/dL, one month after initiating dapagliflozin. During this period, he experienced transient appetite loss associated with a COVID-19 infection. Despite initial management for presumed prerenal AKI, his renal function did not improve with intravenous fluid therapy, and he required hemodialysis. Kidney biopsy revealed characteristic features of osmotic nephropathy, including numerous isometric vacuoles within the epithelial cells of proximal tubules with preserved brush borders. His renal function began to improve approximately two weeks after discontinuation of the SGLT2 inhibitor, and eventually returned to baseline. This case and literature review highlight the potential for osmotic nephropathy as a rare but reversible complication of SGLT2 inhibitor therapy, which may be triggered by volume depletion, particularly in diabetic patients with pre-existing renal dysfunction. Recognition of this underdiagnosed entity is crucial for timely diagnosis and appropriate management.}, }

This systematic review assesses the trends and triggers of HZ as well as the impact after the pandemic, focusing on the changes in the incidence rate among adult and pediatric patients during the last 10 years. All studies published between the years of 2014 and 2024 were accrued, based on a systematic review conducted following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Relevant articles were identified from searches of databases and other sources. Eligibility criteria of studies were applied, and qualitative and quantitative syntheses of studies were performed. A total of 11 studies were included in the review, which examined the association between COVID-19, vaccination, and HZ risk. Several studies suggested that psychological stress and immune dysfunction could be risk factors for HZ incidence. HZ cases after COVID-19 vaccination have been reported, although causation is not established. Based on countries in which COVID-19 was diagnosed, hospitalizations are estimated at 14.4 per 100,000 inhabitants (0.6 to 32.9 per 100,000), and mortality was 1.3 per 100,000, points in this IR Batch (assuming that these are of all diagnosed cases). The risk of HZ reactivation may be increased following COVID-19 infection and vaccination. Higher hospitalization rates with higher mortality risks and neurological consequences were also observed in some populations. Strengthening HZ vaccination programs and studying post-COVID-19 immune responses further can be essential for reducing long-term health risks.}, }

This review article examines the role of biosimilars, mainly in gynecological cancers. The primary focus of this article is to compare the efficacy, safety, and cost-effectiveness of biosimilars, as well as to explore the barriers that restrict their widespread adoption. A comprehensive literature review was conducted, analyzing various studies, regulatory guidelines, and the latest data on biosimilars for the treatment of gynecological cancers. Pivotal trials, such as the GOG-0218, ICON7, and RUBY, were reviewed to assess the efficacy, safety, and cost-effectiveness of these biosimilars. This review highlights key oncologic therapies, including bevacizumab, trastuzumab, pembrolizumab, and their biosimilars, mainly for gynecological cancers. Additionally, this review considers the challenges of immunogenicity, interchangeability, and clinician awareness. After reviewing the latest peer-reviewed literature and related online materials, we found that biosimilars demonstrate comparable efficacy and safety to their reference biologics while also being more cost-effective. Recent clinical trials support the role of biosimilars in limiting the progression of disease and improving overall survival while reducing the financial burden of cancer treatments.}, }

This review focuses on four main topics: (i) coronavirus genome packaging signals (PSs)-how they are found and the function they serve; (ii) the viral components that recognize the PS in order to bring about selective gRNA packaging; (iii) coronavirus nucleocapsid structure and assembly; and (iv) the relationship between nucleocapsid protein phosphorylation and nucleocapsid assembly versus RNA synthesis.

Through anti-inflammatory feedback mechanisms, cytokines contribute to resolution while promoting inflammation in the early stages. The IRE1&#x3b1;-XBP1 axis is activated by SARS-CoV-2-induced endoplasmic reticulum stress, which increases cytokine production and modifies autophagic flux. Concurrently, extracellular vesicles containing cytokines, damage-associated molecular patterns, and viral components are released as secretory autophagy reroutes cytoplasmic cargo toward multivesicular bodies and amphisomes, increasing paracrine immune activation. Suppressed degradative autophagy and increased secretory autophagy-mediated inflammatory signaling are the hallmarks of this pathological state.<br><br>CONCLUSIONS: In severe COVID-19, targeted autophagy restoration is a promising therapeutic approach to restore immune responses, reduce excessive inflammation, and encourage the resolution of cytokine storms.

Although systemic cytokine storm has been reported as a significant factor, the particular intracellular processes through which these viruses affect bone homeostasis are still poorly understood. Recent studies underscore Liquid-Liquid Phase Separation (LLPS) and RNA-Binding Proteins (RBPs) as significant regulatory mechanisms manipulated by these viruses. Particularly, the SARS-CoV-2 Nucleocapsid protein exploits its intrinsically disordered regions to promote LLPS, facilitating viral assembly by the active inhibition of a key host anti-viral mechanism, known as host Stress Granules. Studies suggest that this biophysical interaction can affect the stability of the HuR RBD, impairing the nuclear β-catenin localization and then Wnt-mediated osteogenesis. Despite increasing recognition of post-viral musculoskeletal complications, the mechanistic links between viral persistence, host RBP dysfunction, and impaired bone remodeling remain poorly defined. This review incorporates viral LLPS, stress granule impairment, and osteogenic signaling into a unified 'Two-Hit' pathogenic framework. It also addresses key knowledge gaps, including the lack of longitudinal clinical validation and in vivo evidence associating LLPS impairment to skeletal disorders. Interestingly, this framework represents translational opportunities for dual-action therapeutic strategies that simultaneously impair viral condensates and recover host RBP-associated osteogenic signaling. Targeting the virus-host phase interface can introduce a potential approach not only for antiviral therapies but also for inhibiting post-viral musculoskeletal complications.}, }

Although this phenomenon is known and experienced by everyone, its assessment is not straightforward. The lack of consensus on its definition, complex etiology, and multidimensional nature means that a large number of outcomes exist and continue to be reviewed. However, it seems essential that its assessment be better defined and standardized to understand the effects of physical therapy. To provide an initial exploratory overview, we conducted a rapid scoping review of the various fatigue assessments used in physiotherapy interventions or performed by physical therapists. A total of 139 articles published between 2020 and July 31, 2025 were included and explored. We found 43 different outcomes used across 46 population groups. While the most well-known chronic conditions such as cancer, multiple sclerosis (MS), and coronavirus disease 2019 (COVID-19) are representative, their assessment methods do not appear to be harmonized. These findings from the study support the idea that fatigue remains a complex phenomenon to assess. However, it appears that the lack of justification for the choice of an outcome prevents a better understanding of the reproducible effects on fatigue in physiotherapy interventions.}, }

RNase L degrades host and viral ssRNA, affecting diverse cellular processes including translational arrest, interferon response, and apoptosis, all of which are thought to restrict viral replication. Recent studies of recessive inborn errors of human OAS1, OAS2, and RNase L, however, revealed that for SARS-CoV-2 infection, the main protective action of this pathway in natura may be through restricting phagocyte-driven postviral inflammation rather than restricting early viral replication in the respiratory tract. This finding is consistent with the identification of gain-of-function OAS1 mutations in humans with autoinflammation also driven by myeloid cells. Here, we retrace the investigation of the OAS-RNase L pathway, focusing on these recent in natura studies in humans that reposition the pathway as a determinant of the inflammatory response under natural conditions of infection.}, }

The increasing demand for diagnostic radiography services, driven by advancements in medical technology, an aging population, and the prevalence of chronic diseases, exacerbates these shortages. The COVID-19 pandemic further highlighted workforce vulnerabilities, increasing workloads and burnout. This review examines HHR shortages in radiography in Australia and proposes strategies for sustainable workforce development.<br><br>KEY FINDINGS: The aging radiography workforce, with a significant portion nearing retirement, intensifies HHR shortages. The pandemic disrupted education and training, delaying the entry of new professionals and increasing turnover intentions among existing staff. The result being delayed imaging services, increased wait times, and potentially compromised patient outcomes. To address these challenges, a multifaceted strategy is proposed. Policy changes and government initiatives, including funding educational programs and recognizing internationally trained radiographers, can provide immediate relief. Expanding enrolment capacities and developing new training programs are essential. Retention strategies, including improving working conditions and career advancement opportunities, are crucial for workforce stability. Promoting advanced practice models can optimize task distribution and better utilize specialized skills. Leveraging technology, such as artificial intelligence and telehealth, can enhance productivity and extend service reach.<br><br>CONCLUSION: A comprehensive approach combining policy changes, educational initiatives, retention strategies, technology integration, international recruitment, and awareness campaigns is essential for addressing HHR shortages in radiography. By implementing these strategies, the radiography workforce can be better equipped to meet the growing demands of healthcare, ensuring optimal patient outcomes and the sustainability of health services.<br><br>IMPLICATIONS FOR PRACTICE: Strengthening the radiography workforce will ensure timely and effective healthcare delivery, support health interventions, and progress towards universal health coverage and Sustainable Development Goals.}, }

Yet a mechanistic explanation of disease induction and maintenance is lacking. This hinders the discovery and implementation of biomarkers and treatment options, and ultimately the establishment of effective clinical resolution. Here, we propose that acute viral infection results in (in)direct endothelial dysfunction and senescence, which at the blood-brain barrier, cerebral arteries, gastrointestinal tract, and skeletal muscle can explain symptoms. The endothelial senescence-associated secretory phenotype (SASP) is proinflammatory, pro-oxidative, procoagulant, primed for vasoconstriction, and characterized by impaired regulation of tissue repair, but also leads to dysregulated inflammatory processes. Immune abnormalities in ME/CFS and long COVID can account for the persistence of endothelial senescence long past the acute infection by preventing their clearance, thereby providing a mechanism for the chronic nature of ME/CFS and long COVID. The systemic and tissue-specific effects of endothelial senescence can thus explain the multisystem involvement in and subtypes of ME/CFS and long COVID, including dysregulated blood flow and perfusion deficits. This can occur in all tissues, but especially the brain as evidenced by findings of reduced cerebral blood flow and impaired perfusion of various brain regions, post-exertional malaise (PEM), gastrointestinal disturbances, and fatigue. Paramount to this theory is the affected endothelium, and the bidirectional sustainment of immune abnormalities and endothelial senescence. The recognition of endothelial cell dysfunction and senescence as a core element in the aetiology of both ME/CFS and Long COVID should aid in the establishment of effective biomarkers and treatment regimens.}, }

Advantages such as mobility, ease of use and lack of requirement for cleaning staff during the COVID-19 pandemic led to a global increase in usage, with many companies developing SUFB as part of their bronchoscopy portfolio. In parallel, there has been more attention and initiatives to minimise the risk of infection transmission related to bronchoscopy. RFB requires maximum adherence to manufacturer-recommended cleaning protocols. However, evidence of transmissible organisms after cleaning is reported in healthcare settings of all types.

Recent data show a critical role of neutrophils at various stages of viral and bacterial infections, revealing how early activation of neutrophils could help mitigate infectious diseases. It could prevent the gradual overactivation of subclasses of neutrophils and probably not induce it. In respiratory virus infections, an immune delay of several days allows the development of a high viral load supporting infectivity towards further hosts when a delayed and increased immune response takes place. Virus variants will optimize immune delay towards highest infectivity, supporting pandemic potential. The influenza virus, coronavirus, and several major bacterial infections exhibit such immune delay capability. Recurrent urinary tract infections (rUTI) are common, often associated with the causative uropathogenic E. coli (UPEC) that has this capability, suggesting that immune delay is crucial in the pathogenesis of rUTI and other widespread bacterial infections. Counteracting immune delay, therefore, is a promising approach for mitigating infectious diseases with epidemic and pandemic presence or potential. Previously proven low-frequency electromagnetic field (LF-EMF)-induced neutrophil activation is such an approach.}, }

Their high mutation rates undermine the effectiveness of conventional direct-acting antivirals (DAAs) and facilitate drug resistance. As obligate intracellular parasites, RNA viruses rely extensively on host cellular machinery and metabolic pathways throughout their life cycle. This dependency has prompted a strategic shift in antiviral research-from targeting the mutable virus to targeting relatively conserved host dependency factors (HDFs). In this review, we systematically analyze how RNA viruses exploit HDFs at each stage of infection: utilizing host receptors for entry; remodeling endomembrane systems to establish replication organelles; hijacking transcriptional, translational, and metabolic systems for genome replication and protein synthesis; and co-opting trafficking and budding machinery for assembly and egress. By comparing strategies across diverse RNA viruses, we highlight the broad-spectrum potential of HDF-targeting approaches, which offer a higher genetic barrier to resistance, providing a rational framework for developing host-targeting antiviral therapies.}, }

The hypothesis described here proposes that Long COVID is best understood as a disorder of persistent immune dysregulation, with chronic macrophage activation representing the fundamental underlying pathophysiology. Unlike transient post-viral syndromes, Long COVID involves a sustained innate immune response, particularly within monocyte-derived macrophages, driven by persistent spike protein (peripherally in MAIT cells and centrally in Microglial cells), epigenetic imprinting, and gut-related viral reservoirs. These macrophages are not merely activated temporarily but also become epigenetically "trained" into a prolonged inflammatory state, as demonstrated by enduring histone acetylation markers such as H3K27acDNA Reprogramming. It is proposed that recognizing macrophage activation as the central axis of Long COVID pathology offers a framework for personalized risk assessment, targeted intervention, and therapeutic recalibration.}, }

Long COVID (LC) is characterized by persistent symptoms such as fatigue, dyspnea, cognitive impairment, and palpitations. Mechanistically, SARS-CoV-2 induces direct endothelial injury, promotes a pro-inflammatory cytokine milieu, and activates platelets, leading to immunothrombosis and impaired fibrinolysis. Consequently, patients exhibit microthrombosis, elevated plasma D-dimer, fibrinogen dysregulation, and persistent hypercoagulability. Clinically, this translates into an increased risk of venous thromboembolism, including deep vein thrombosis and pulmonary embolism, as well as arterial thrombotic events such as myocardial infarction and stroke, which may persist months after acute infection. Understanding the interplay between endothelial injury, inflammation, and coagulation is crucial for risk stratification and the development of preventive and therapeutic strategies. We conducted a systematic narrative review of the literature, including human clinical and mechanistic studies identified through PubMed, Scopus and Web of Science up to 30 September 2025.

However, a clear classification of these cognitive deficits and molecular blood events over time is still lacking. This narrative review summarizes the neuropsychological consequences of COVID-19 and evidence of altered cytokines and BBB disruption as potential mediators of cognitive impairment across post-infection phases. Post-COVID-19 cognitive dysfunction appears to follow a temporal course, evolving from acute focal deficits in attention, working memory, and executive function to more persistent multidomain impairments. We reviewed key cytokines released into the blood during COVID-19 infection, including antiviral (IFNγ, CXCL1, CXCL10), inflammatory (IL-1β, IL-2, IL-4, IL-6, IL-7, IL-8, IL-10, GM-CSF, TNFα), and monocyte chemoattractants (MCP1/CCL2, MCP3/CCL7, MIP-1α/CCL3, GM-CSF, G-CSF). This analysis shows that several inflammatory and viral cytokines remain elevated beyond the acute phase and are associated with cognitive deficits, including IL-6, IL-13, IL-8, IL-1β, TNFα, and MCP1 in long-term post-COVID-19 patients. In addition, we examined studies analyzing changes over time in neurovascular unit proteins as biomarkers of BBB disruption, including extracellular matrix proteins (PPIA, MMP-9), astrocytes (S100β, GFAP), and neurons (NFL). These proteins are elevated in acute COVID-19 but generally return to control levels within six months, suggesting BBB restoration. However, in patients followed for over a year, BBB disruption persists only in those with cognitive impairment and is associated with systemic inflammation, with TGFβ as a related biomarker. Although cognitive sequelae can persist for over 12 months after SARS-CoV-2 infection, further studies are needed to investigate long-term neurocognitive outcomes and their link to sustained proinflammatory cytokine elevation and brain impact.}, }

The COVID-19 era reshaped control norms-normalizing N95 use during surges, ventilation improvements, and routine multiplex PCR-creating an opportunity to strengthen hospital outbreak management. Methods: We conducted a targeted narrative review of WHO/CDC/Infectious Diseases Society of America (IDSA) guidance and peer-reviewed studies (January 2015-August 2025), emphasizing adult inpatient care. This narrative review synthesizes recent evidence and discusses theoretical implications for practice, rather than establishing formal guidelines. Evidence was synthesized into pragmatic practice statements on detection, diagnostics, isolation/cohorting, antivirals, chemoprophylaxis, vaccination, surveillance, and communication. Results: Early recognition and test-based confirmation are pivotal. For inpatients, nucleic-acid amplification tests are preferred; negative antigen tests warrant PCR confirmation, and lower-respiratory specimens improve yield in severe disease. A practical outbreak threshold is ≥2 epidemiologically linked, laboratory-confirmed cases within 72 h on the same ward. Effective control may require immediate isolation or cohorting with dedicated staff, strict droplet/respiratory protection, and daily active surveillance. Early oseltamivir (≤48 h from onset or on admission) reduces mortality and length of stay; short-course post-exposure prophylaxis for exposed patients or staff lowers secondary attack rates. Integrated vaccination efforts for healthcare personnel and high-risk patients reinforce workforce resilience and reduce transmission. Conclusions: A standardized, clinician-led bundle-early molecular testing, do-not-delay antivirals, decisive cohorting and Personal protective equipment (PPE), targeted chemoprophylaxis, vaccination, and disciplined communication- could help curb transmission, protect vulnerable patients and staff, and preserve capacity. Hospitals should codify COVID-era layered controls for seasonal influenza and rehearse unit-level outbreak playbooks to accelerate response and recovery.

Methods: We performed a systematic review and meta-analysis of adults (≥18 years) initiated on HFNC in non-ICU wards. Primary outcomes were in-hospital (or 28-day) mortality and ICU transfer; where available, we compared mortality for HFNC vs. conventional oxygen therapy (COT) in do-not-intubate (DNI) cohorts. Observational studies and trials were eligible. Random-effects models synthesized proportions and risk ratios; risk of bias (ROBINS-I/RoB 2) and certainty (GRADE) were assessed. Results: Ten studies met the inclusion criteria for any-ward HFNC; subsets contributed data to pooled analyses. Across all non-ICU wards (general wards plus step-up IMCU/HDU), pooled mortality was 14.0% (95% CI 4.6-35.5; I[2] ≈ 92%). Pooled ICU transfer after ward/step-up HFNC start was 20.0% (95% CI 6.3-48.1; I[2] ≈ 97%). Restricted to internal medicine/respiratory wards, pooled mortality was 19.8% (95% CI 7.1-44.2; I[2] ≈ 95%) and ICU transfer 31.2% (95% CI 9.9-65.0; I[2] ≈ 97%). In step-up units (IMCU/HDU), ICU transfer appeared lower and less variable (22.0% [95% CI 16.5-28.8]; I[2] ≈ 10%), suggesting environment-dependent outcomes. In a multicenter DNI COVID-19 cohort, HFNC vs. COT showed no clear mortality difference (RR ≈ 0.90, 95% CI 0.75-1.08; adjusted OR ≈ 0.72, 95% CI 0.34-1.54). Certainty of evidence for all critical outcomes was very low due to observational design, high inconsistency, and imprecision. Conclusions: HFNC outside the ICU is feasible, but it is related to nontrivial mortality and frequent escalation-particularly on general wards-while step-up units demonstrate more reproducible trajectories. Outcomes appear strongly conditioned by care environment, staffing, monitoring, and escalation pathways. Given very low certainty and substantial heterogeneity, institutions should pair ward HFNC with protocolized reassessment and rapid response/ICU outreach, and future research should prospectively compare ward HFNC pathways against optimized COT/NIV using standardized outcomes.}, }

Unlike conventional monoclonal antibody (mAb) therapies, which rely on labor-intensive and time-consuming cell culture production, mRNA-encoded antibodies offer a faster, scalable, and cell-free approach that bypasses protein purification and cold-chain constraints. This strategy has demonstrated considerable promise during the COVID-19 pandemic, where Moderna's mRNA-1940, an mRNA-based neutralizing antibody targeting the SARS-CoV-2 spike protein, entered preclinical and early-phase trials within months of viral emergence, underscoring the potential for rapid response in outbreak settings. The platform leverages advances in nucleoside-modified mRNA, codon optimization, and lipid nanoparticle (LNP) delivery systems to achieve transient, high-level expression of functional antibodies with reduced innate immune activation. Beyond COVID-19, mRNA-encoded antibody approaches have been explored in preclinical models of Zika virus, Ebola virus, and rabies, where a single intramuscular dose provided prophylactic and therapeutic benefits in animal models. As the world faces recurrent viral threats, the development of mRNA-encoded antibodies as a plug-and-play system offers a compelling, adaptable, and clinically feasible strategy for infectious disease preparedness.

These interactions determine the molecular stability, reactivity and solubility of drugs in different biocompatible solvents. The knowledge about their absorption, distribution, metabolism, transport and bioavailability can be enhanced from their molecular interactions data. There have been reports of improved solubility and stability of drugs like metformin hydrochloride and hydralazine hydrochloride in aqueous solutions of carbohydrates and amino acids, which has an immediate effect on their bioavailability and treatment efficacy. Moreover, the COVID-19 pandemic has reestablished the importance of this review, as some drugs were clinically approved after proving their activity and efficacy during this phase. The antivirals favipiravir, remdesivir and two repurposed drugs, antimalarial hydroxychloroquine and metabolic inhibitor 2-deoxy-d-glucose (2-DG) were approved during this phase based on their available physicochemical data. These results established the clinical efficacy and dependency of drugs on their solvation environment, highlighting the pharmacological importance of studying molecular interactions in addition to their theoretical significance. The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) model was adopted to conduct this systematic review, covering scientific articles from 2000 to 2025 to ensure a careful evaluation of recent advancements. This review focuses on the molecular interactions of various drugs with different biological solvent systems, using physicochemical, spectroscopic, and computational methods. It critically examines drug-solvent interactions by specifying quantitative physicochemical (free energy changes), spectral (binding constant) and computational metrics (binding affinity). This integrated approach provides a novel molecular-level insight into the structural, solvation, and interaction behavior of drugs under physiological conditions. The integration of molecular dynamics, artificial intelligence/machine learning tools, and experimental validation represents a prospective approach for addressing current limitations, contributing to the development of precision in drug delivery strategies for personalized medications. This review could be substantial for biochemical and medicinal sectors with important implications in formulation, stability, bioavailability, and solubility of drugs in clinical pharmacology. The outcome may provide an important basis for advanced research in future, serving the scientific community in understanding pharmacokinetics and pharmacodynamics of drug interactions. This can further strengthen the advanced research in future, involving drug-solvent interactions, which ultimately improves the safety, treatment efficacy and delivery performance of the drugs.}, }

Papers were further filtered using a structured screening process to ensure empirical and intervention-based modelling.<br><br>DATA EXTRACTION AND SYNTHESIS: Data were extracted from eligible studies and categorised according to modelling approaches, data sources, intervention types and reported effectiveness. Descriptive synthesis was performed to summarise modelling trends and intervention performance. Studies were classified into major intervention categories, including tracing, testing and isolation (TTI); physical and social distancing (PSD); vaccination; lockdowns; mask-wearing; home office or stay-at-home (HOSH) and health infrastructure enhancement (HIE).<br><br>RESULTS: Out of 2297 studies identified, 126 met inclusion criteria. Compartmental models were the most frequently used approach, primarily relying on case and death counts to assess intervention impact. The most commonly reported effective interventions were TTI, PSD, vaccination, lockdowns, mask-wearing and HOSH. When considering effectiveness relative to study frequency, the top six interventions were TTI, HOSH, mask-wearing, HIE, PSD and lockdowns. The relatively lower representation of vaccination reflects that most included studies were conducted during the early stages of the pandemic, before widespread vaccine rollout and availability of empirical vaccination data.<br><br>CONCLUSIONS: This review highlights the critical role of data-driven models in guiding COVID-19 response strategies. Evidence supports the combined effectiveness of non-pharmaceutical interventions, robust testing and tracing systems and health infrastructure strengthening. Real-world impact, however, remains dependent on local healthcare capacity, socioeconomic conditions and cultural contexts. Continued research is essential to refine adaptive modelling approaches and strengthen preparedness for future public health emergencies.}, }

The complexity of its pathogenic mechanisms and host interactions urgently requires high-fidelity animal models to support research. Humanized mouse models break the species barrier through gene editing and immune reconstitution technologies, providing a key tool to simulate human infection characteristics and pathological processes. A number of studies have reported the application of humanized mouse models in the fields of COVID-19 research, such as SARS-CoV-2 pathogenesis, anti-SARS-CoV-2 drug discovery and vaccine development, etc. The present review aimed to systematically document the latest advances in the application of humanized mouse models based on different construction strategies, such as receptor humanization, immune system humanization and composite humanization. These models have not only elucidated the pathogenicity differences and immune escape mechanisms of SARS-CoV-2 variants, but have also validated the efficacy of broad-spectrum anti-SARS-CoV-2 strategies, including angiotensin-converting enzyme 2-targeted therapies, antibody cocktail regimens and mucosal vaccines. Additionally, humanized mouse models have played a pivotal role in investigating the mechanisms underlying long COVID. By revealing the multi-system pathogenic mechanisms of pulmonary fibrosis, neurodegeneration and intestinal microbiota dysregulation, these models provide a theoretical foundation for the development of targeted intervention strategies.}, }

NO sits at the crossroads of these pathways, acting both as an antiviral modulator of spike-ACE2 interactions and as a downstream mediator of Mas-dependent endothelial protection. This review summarizes evidence on NO across three layers: (i) viral entry (S nitrosylation of spike/ACE2, protease modulation), (ii) cardiovascular comorbidities (hypertension, obesity, diabetes) where ACE2 downregulation impairs endothelial NO synthase (eNOS)-dependent NO production and promotes thrombosis and microvascular dysfunction, and (iii) neurovascular/ neurodegenerative sequelae, in which renin-angiotensin-aldosterone system (RAAS) dysregulation along with imbalance between protective eNOS/nNOS and inflammatory iNOS fosters blood-brain barrier disruption, microthrombosis, and cognitive impairment. Shared mechanisms - endotheliitis, microvascular dysfunction, and neuroinflammation may explain convergent risks for cardiac injury and cognitive decline in long COVID-19. Putative therapeutic strategies may include restoring physiological NO (via Mas agonism, Ang-(1-7), inhibition of Ang 1-7 degradation and recombinant ACE2), pulmonary-selective inhaled NO, hybrid S nitrosylated agents, and selective attenuation of iNOS/peroxynitrite alongside endothelial support. Targeted modulation - enhancing eNOS/nNOS while constraining iNOS offers a unified framework to mitigate both cardiovascular and neurodegenerative consequences of COVID-19.}, }

Among the purinergic receptors expressed in these cells, P2Y14 has gained increasing attention in recent years for its role in modulating neutrophil recruitment and activation in inflammatory contexts. This receptor is activated mainly by uridine diphosphoglucose (UDP-glucose) and other UDP-sugars released during cellular stress or damage. Through the activation of G protein-coupled pathways, particularly via Gi/o and RhoA signaling, P2Y14 influences key neutrophil functions, including chemotaxis, cytoskeletal rearrangements, and oxidative responses. Despite its pro-inflammatory potential, and the increasing amount of literature data in recent years, P2Y14's complete physiological and pathological roles remain underexplored. Literature data also highlight its involvement in diseases like glioblastoma and COVID-19, where, due to increased neutrophil infiltration, it exacerbates inflammation, tissue damage, and stress. Therefore, targeting P2Y14 may be a promising strategy to modulate neutrophil chemotaxis and mitigate unwanted harmful inflammatory responses. This review discusses the characteristics and signaling mechanisms of P2Y14 in neutrophils, as well as the relevant implications of this pathway for neutrophil function.}, }

Eligible studies were those on adults (&#x2265;18 years) with confirmed severe acute respiratory syndrome coronavirus 2 infection and that included intubation and mortality as primary outcomes. Risk of bias was assessed using the National Institutes of Health Quality Assessment Tool for Observational Cohorts and the Cochrane Risk of Bias tool.

We asked, "What is known about how mental health practitioners view the integration of smartphone apps into their practice?" Further, this scoping review explored the factors that might influence integration of smartphone apps into practice, such as practitioner and client characteristics, app design and functionality, and practitioner views.<br><br>METHODS: We conducted a systematic search of 3 databases that yielded 38 studies published between 2018 and 2025, involving 1894 participants across various mental health disciplines, most predominantly psychologists and psychiatrists. Data were collected on practitioner and client characteristics, app functionality, and factors deemed important or influencing practitioners' opinions about app integration.<br><br>RESULTS: The included studies were most likely to explore use of apps outside the clinical session and focused on self-management apps for mental health monitoring and tracking, and for collecting data from the patient. Fewer studies explored use of apps within-session, or practitioner-guided apps.

Despite their advantages in terms of durability, affordability, and ease of production, the accumulation of plastics has resulted in considerable pollution. The SARS-CoV-2 pandemic further exacerbated plastic consumption, particularly in medical supplies, intensifying the plastic waste crisis. The majority of plastics are not recycled and eventually degrade into microplastics (MPs) and nanoplastics (NPs), which pose substantial risks to ecosystems and human health. MPs and NPs enter the body through inhalation, ingestion, or skin contact and have been found in biological samples such as blood, faeces, and lung fluids. Their presence has been linked to diseases affecting the lungs, cardiovascular system, and intestines, as well as cancer and viral infections. This review highlights how MPs and NPs contribute to the spread of infectious diseases by creating a habitat called the "plastisphere," which promotes microbial growth and serves as a reservoir for pathogens, emphasising their effects on viral persistence, infection dynamics, and immune modulation. Unlike previous reviews mainly focused on toxicological or microbiological aspects, this work integrates environmental, virological, and immunological evidence to outline how MPs/NPs may reshape virus-host interactions. By identifying critical knowledge gaps, such as the quantitative impact of MPs/NPs on viral stability and immune disruption, this review provides a background for future experimental and epidemiological research.

Predominantly expressed by neutrophils and monocytes, CLP is released in response to infection or inflammation and serves as a potent antimicrobial and pro-inflammatory mediator.<br><br>METHODS: We performed a systematic search of electronic databases to identify studies evaluating serum CLP in inflammatory diseases.<br><br>RESULTS: Serum CLP levels are elevated in numerous inflammatory conditions, making it a valuable biomarker for disease activity, prognosis, and therapeutic monitoring. In rheumatoid arthritis (RA), CLP reflects disease severity more accurately than conventional markers like CRP and ESR, correlates with radiographic progression, and is strongly expressed at inflammation sites. In juvenile idiopathic arthritis (JIA), serum CLP levels are significantly higher in active, treatment-na&#xef;ve patients and correlate well with clinical activity. In spondyloarthritis (SpA), especially ankylosing spondylitis, CLP levels tend to be elevated, though results vary among studies. In inflammatory bowel disease (IBD), CLP is proposed as a non-invasive marker for disease burden and response to treatment. It is especially useful in systemic inflammation assessment. Elevated CLP levels are also observed in psoriasis, Beh&#xe7;et's disease, ANCA-associated vasculitis, and preeclampsia. CLP has emerged as a promising prognostic marker in bacterial infection and coronavirus disease 2019 (COVID-19), with higher levels correlating with ICU admission and disease severity.<br><br>CONCLUSIONS: Serum CLP is a promising inflammatory biomarker, though disease specificity remains limited.}, }

Beyond the prevention of neurological injury associated with seasonal influenza, vaccination may help mitigate vascular and neuroinflammatory injury underlying cognitive impairment. Influenza infection can cause a marked short‑term increase in myocardial infarction risk, and acute infections have also been associated with transient increases in stroke risk. Experimental models show prolonged microglial activation and synaptic loss even from non-neurotropic strains - processes likely modulated by vaccination. Epidemiologic data consistently support this evidence; a 2023 meta-analysis, including observational studies, of ~ 2.09 million adults identified a 31% lower risk of incident dementia; US matched cohorts demonstrated 40% lower risk of Alzheimer's disease (absolute decrease 3.4%); Veterans Health data showed a 0.86 hazard ratio for dementia; and UK Biobank data showed lower risk for all-cause (0.83 h), and vascular dementia (0.58 h) with a dose-response association by vaccination term. Randomized trials suggest fewer adverse cardiovascular events in vaccine recipients giving even more biological plausibility to this concept. Despite that, prevention through influenza vaccination is not fully realized in older adults due to low levels of perceived risk, vaccine confidence, and variations in clinical practice guidance. This public health perspective reviews the physiopathological and epidemiological evidence in support of influenza vaccination as a pragmatic, dementia risk-modifying intervention within healthy aging strategies and encourages the inclusion of vaccination status in hospital discharge and chronic-care pathways, integration of cognitive outcomes in monitoring, and equity-centered research to eliminate barriers to behavioral and implementation.}, }

This review synthesizes emerging evidence on shared pathophysiological pathways and evaluates the therapeutic potential of dietary and weight management strategies.<br><br>RECENT FINDINGS: Cognitive symptoms such as brain fog and memory deficits are among the most persistent and disabling features of long COVID. Obesity is associated with more severe manifestations through pathways involving chronic systemic inflammation, compromised blood-brain barrier integrity, and neuroimmune dysregulation. Concurrently, malnutrition and poor diet quality including low intake of antioxidants, omega-3 fatty acids, and micronutrients may impair neuroplasticity and delay recovery. Interventions such as Mediterranean and ketogenic dietary patterns, as well as structured weight loss programs, show promise in reducing inflammation and improving cognitive outcomes. Obesity and suboptimal nutritional status amplify the neurocognitive burden of long COVID through shared pathophysiological mechanisms. Integrated care models that incorporate metabolic screening, nutritional assessment, and individualized dietary interventions may improve recovery trajectories. Public health strategies that address food quality, obesity prevention, and equitable access to nutrition care are essential for long-term resilience in the post-COVID era.}, }

Clinical translation of small interfering RNA (siRNA), however, faces substantial obstacles, notably cross-strain universality, off-target effects, and targeted delivery. This review summarizes recent advances in RNAi-mediated inhibition of coronaviruses at the genomic level, emphasizing RNAi applications to impede SARS-CoV-2 replication and transmission. By evaluating RNAi strategies aimed at specific viral components-RNA-dependent RNA polymerase (RdRp), spike protein (S), envelope protein (E), membrane protein (M), nucleocapsid protein (N), and other essential genes-we illustrate the distinct specificity and efficacy of RNAi across binding sites and identify candidate universal targets for human-transmitted coronaviruses. We also assess the strengths and limitations of delivery platforms, including liposomes, polymers, nanoparticles, and viral vectors.

While the escalating impact of intimate partner violence during the COVID-19 pandemic has been widely acknowledged, there remains a need for a comprehensive systematic review that synthesizes existing literature. This review seeks to address this gap by providing an inclusive assessment of the global landscape of intimate partner violence during and after the pandemic, thereby informing more effective prevention and intervention strategies.<br><br>METHODS: A systematic literature search was conducted on PubMed, Google Scholar, and Scopus databases using different MeSH terms. A total of 445 relevant articles were identified initially, and after thorough screening, 54 articles were included in the review.<br><br>RESULTS: The lockdown had several negative consequences, including job losses, economic vulnerability, and health issues due to prolonged loneliness and uncertainty. An increase in emergency hotline or Women's Helpline calls was observed. Globally, intimate partner violence surged during the lockdown and persisted into 2023, causing severe and lasting health, psychological, and reproductive consequences for victims. Our results showed that COVID-19 increased the risk of partner violence: post-COVID intimate partner violence risk greater than pre-COVID risk (0.33 vs. 0.28, respectively).<br><br>CONCLUSION: Although COVID-19 increased the risk of intimate partner violence, this review also stresses a high global prevalence of intimate partner violence, not restricted to the pandemic and lockdowns.

It is well known that conflict is accompanied not only by significant losses among both military personnel and civilians but also by rising levels of stress and stress-related disorders within the general population. Stress is bidirectionally connected with the state of the gut microbiota through the gut-brain axis. Dietary factors and eating behaviours also play crucial roles in shaping gut microbiota composition. On the one hand, conflict negatively affects food availability and dietary patterns, leading to reduced meal frequency and potentially diminishing microbiota diversity. On the other hand, stress-induced alterations in eating behaviour, such as bulimia or anorexia, can further impair gut microbiota composition. Additionally, individuals in conflict zones face heightened risks of infectious diseases due to disrupted vaccination schedules, poor sanitation, and limited access to clean drinking water. Stress-related immune changes may increase susceptibility to infections and raise the likelihood of adverse outcomes. Moreover, the frequent use of antibiotics to treat infections during conflicts contributes to reduced gut microbiota diversity. This review narratively examines the complex interactions among stress, immune responses, dietary patterns, infectious diseases, and gut microbiota in conflict-affected areas, and provides new perspectives on the role of artificial intelligence in modelling such comorbid pathologies.}, }

Although repeated booster vaccinations enhance protection against severe illnesses in immunocompromised individuals, they remain at heightened risk of adverse outcomes. This underscores the crucial need for effective pharmacologic strategies to prevent and treat infection. This review examines current strategies for preventing severe COVID-19 in patients with HM, focusing on pre-exposure prophylaxis and early treatment of COVID-19. New monoclonal antibodies have been developed, offering effective pre-exposure prophylaxis. Antiviral agents and monoclonal antibodies demonstrated efficacy in limiting severe COVID-19 outcomes in patients with HM, though some patients, particularly the elderly, remain at risk of critical illness and death. Prolonged infection over months is also common, particularly in patients with lymphoid malignancies. Sustained viral shedding and ongoing mutation may be associated with chronic symptoms and is the likely source of several novel variants of concern that prolonged the pandemic. While HM subtype and advanced age are risk factors for severe or persistent COVID-19, there are no accurate tools for predicting individual risk. Given this uncertainty, prompt medical consultation, timely prescription of antiviral agents, and close monitoring are essential to minimize the risk of adverse outcomes in this vulnerable population.}, }

This perspective highlights five studies on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), human immunodeficiency virus type 1 (HIV-1), monkeypox virus (MPXV), influenza A virus (IAV), and Hepatitis B virus (HBV), revealing novel resistance mechanisms and innovative strategies. For SARS-CoV-2, GC376's flexible benzyl group overcomes nirmatrelvir resistance. HIV-1's non-nucleoside reverse transcriptase inhibitors (NNRTIs) 5i3 adapts to resistant mutants via a quinazoline scaffold, while MPXV's tecovirimat acts as a "molecular glue" stabilizing F13 dimers. Expanding these paradigms, we present groundbreaking insights: An indazole-based IAV inhibitor (compound 24) disrupts the conserved PA-PB1 heterodimer, showing sub-micromolar potency against resistant strains. For HBV, a hydrophobic tagging degrader (HyT-S7) induces HBc degradation, bypassing resistance mutations impairing traditional capsid modulators.

This review explores the role of oxidative stress and trace element deficiencies in the pathogenesis of bronchiolitis and its long-term sequelae. Infants with reduced lung function due to prematurity or congenital airway anomalies exhibit heightened susceptibility to RSV infection. Growing evidence implicates oxidative stress and deficiencies in zinc, selenium, and magnesium as significant contributors to disease progression. Impaired antioxidant defenses exacerbate viral inflammatory responses, leading to prolonged symptoms and recurrent wheezing with potential developmental delays. Studies consistently demonstrate that children with bronchiolitis exhibit elevated oxidative stress markers and reduced antioxidant capacity, with trace element deficiencies correlating with disease severity. Reduced defenses against oxidative stress may be associated with recurrent wheezing episodes, which are more frequent after rhinovirus bronchiolitis than after RSV bronchiolitis. Thus, RSV and rhinovirus (RV) bronchiolitis may unmask pre-existing vulnerabilities rather than directly causing long-term damage associated with later asthma. Micronutrient supplementation, particularly zinc and selenium, has shown potential in reducing respiratory infection duration and severity. COVID-19 pandemic evidence further supports nutritional status as a key modulator of respiratory disease outcomes, with nutraceuticals like curcumin and flavonoids demonstrating anti-inflammatory benefits. Given the safety and accessibility of micronutrient supplementation, early nutritional assessment and intervention in high-risk infants may offer a cost-effective strategy to improve long-term respiratory outcomes. Bronchiolitis should be viewed as a clinical signal warranting proactive, holistic pediatric care rather than merely an acute illness.}, }

Environmental surveillance, particularly through wastewater monitoring, has proven valuable for tracking viral circulation and variant shift during the COVID-19 pandemic, yet its application to HEV is still limited. In this review, we systematically analyzed HEV sequences across Europe, focusing on environmental sources from a genetic perspective. Of more than 13,100 HEV sequences deposited in the NCBI database, only 2.4 % (316/13,118) originated from environmental samples, including wastewater, surface water, and biosolids. Additional typing data from the literature revealed highly uneven geographic distribution, with 97 % of environmental sequences reported from Italy, France, the United Kingdom (UK), Spain, Sweden, and Germany. HEV-3 was the dominant genotype, while HEV-1 and HEV-4 were occasionally detected. Subtypes 3c and 3f were most common, but their prevalence varied across countries and sample types. Some countries, such as France, Sweden, and the UK, exhibited divergent subtype patterns between humans, animals, and environmental sources, whereas others, such as Spain and Germany, showed more consistent distributions. These findings highlight the importance of integrating clinical, veterinary, and environmental surveillance to better understand HEV transmission in Europe under a One Health framework. However, the scarcity of environmental data, technical challenges in sequencing, and lack of standardized protocols limit comprehensive assessment of HEV circulation.

It often results from disrupted sleep patterns and shift work and increases the risk of critical incidents in the clinical practice. Anesthetists are particularly affected as irregular working hours and frequent night shifts disrupt their circadian rhythms. Although fatigue is reversible with appropriate measures, it remains largely unrecognized as a structural issue within the German healthcare system.Over recent decades the working conditions across European healthcare settings have steadily deteriorated, a trend that culminated during the COVID-19 pandemic. This period clearly highlighted the urgent need to prioritize the well-being of healthcare professionals. The aim of this review article is to raise awareness of fatigue and provide insights into effective management strategies. It explores both international concepts and local solutions relevant to the German system.This review and analysis are based on studies and material developed as part of the European "Fatigue Project" and the "Fight Fatigue" campaign. It examines the effects of fatigue across all career stages and identifies practical strategies for risk reduction.The results show that fatigue affects anesthetists at all stages of their careers. Structured fatigue management is therefore a vital component of sustainable healthcare provision. In particular, fatigue risk management systems and optimized shift work planning have proven effective in reducing the burden on personnel and enhancing patient safety.}, }

Studies were included if they evaluated crowding causes, consequences, or interventions, using metrics such as ED length of stay, boarding, or left without being seen. Four reviewers independently screened titles, abstracts, and full texts. Study quality was assessed using the Scottish Intercollegiate Guidelines Network (SIGN) critical appraisal tools. This review was registered with PROSPERO (CRD420251117676).<br><br>RESULTS: Of 23,408 studies identified, 226 met inclusion criteria. Most studies were retrospective (83%) and of low (62%) or acceptable (35%) quality. Crowding was primarily driven by input (high patient volumes, limited primary care access), throughput (staffing shortages, laboratory and imaging delays), and output (boarding, late discharges) factors. Adverse effects included increased mortality, treatment delays, prolonged inpatient stays, higher rates of patients leaving without being seen, and reduced patient satisfaction. Effective strategies included provider-in-triage, nurse-initiated orders, and split-flow models. Output-focused interventions, such as active bed management and early discharge protocols, required system wide coordination. The COVID-19 pandemic shifted patient volumes and led to innovative solutions such as drive-through clinics and repurposed spaces to alleviate surges.<br><br>CONCLUSION: ED crowding is a persistent global issue with significant clinical and operational consequences.

PF-07321332 (nirmatrelvir) emerged as a potential oral clinical candidate within ∼ 6 months from the time discovery efforts were first initiated. The review also delves into a discussion around the successful use of quantitative fluorine-19 nuclear magnetic resonance spectroscopy in the characterization of the human mass balance and excretion pathways of nirmatrelvir. Human absorption, distribution, metabolism, and excretion data that emerged from the fluorine-19 nuclear magnetic resonance study were used to support the Emergency Use Authorization and new drug application filing, which was accepted by regulatory agencies worldwide.

There have been over 228,000 excess CVD deaths through 2022,1 undoubtedly partially due to the COVID-19 pandemic, but the mortality rate continues to rise (arguably due to the rising epidemic of obesity and diabetes). CVD remains the leading cause of death in developed countries, accounting for over 30% of deaths, and risk estimation is a cornerstone approach to guiding CVD prevention in clinical medicine. Data from the CDC reveal that 36% of US adults have no CVD risk factors, 35% have 1, and 29% have 2 or more risk factors. The age-adjusted percentage of adults with 2 or more CVD risk factors has increased between 2013-2014 to August 2021-August 2023, especially in older age groups.2 Assessing the risk for CVD mortality is essential for the disability and life insurance industry required to assess that risk at a single point in time (at the issuance of an insurance policy). Evaluating this risk requires careful attention to modifiable and non-modifiable factors, including hypertension and other co-morbidities, abnormal lipid profiles, and lifestyle inequalities. The goal of this treatise is to evaluate the various CVD calculators, but also to review other risk factors that may not be routinely sought in estimating CVD risk. The importance of apolipoproteinB (apoB) and lipoprotein A (LpA) as better risk predictors than just elevated LDL levels will be emphasized, and evidence of systemic inflammation and insulin resistance will be proposed as essential early indicators of future cardiovascular disease.}, }

These small non-coding RNAs inhibit translation by binding to target mRNAs, often within a complex regulatory network involving other RNA species such as circular RNAs and long non-coding RNAs. miRNAs are now recognised as central players in the pathogenesis, immune modulation, and progression of infectious diseases. In this review, we thoroughly examine studies published over the past five years, focusing on miRNAs involved in immune regulation during four major viral infections: severe acute respiratory syndrome coronavirus 2, hepatitis B virus, human immunodeficiency virus, and herpes simplex virus. Our analysis centres on the core signalling pathways most frequently targeted by miRNAs: NF-κB, MAPK, JAK-STAT, TGF-β/Smad, and pattern-recognition receptor-associated cascades. Among the miRNAs most prominently implicated are miR-21, miR-146a, miR-150, and miR-155. These miRNAs modulate key signalling pathways, thereby influencing macrophage polarisation, T- and natural killer cell activity, antigen presentation, and inflammatory cytokine production. In addition, virus-encoded miRNAs and ceRNA or extracellular vesicle-mediated interactions are discussed where mechanistically validated, illustrating virus-specific regulatory layers. Collectively, this integrative synthesis underscores the pivotal roles of miRNAs in orchestrating antiviral immunity and highlights their potential as biomarkers and therapeutic targets in viral infections. A better understanding of miRNA-mediated immunoregulation may pave the way for precision interventions aimed at improving immune control and patient outcomes.}, }

Although these approaches achieve excellent results, venetoclax doublets have diminished efficacy in high-risk biological subgroups, and indefinite covalent Bruton tyrosine kinase inhibitor (cBTKI) is associated with cumulative cardiovascular and infectious toxicity. Triplet regimens for treatment of CLL involve simultaneous use of cBTKI, venetoclax, and anti-CD20 monoclonal antibody. Three major frontline Phase 3 trials (CLL-13/GAIA, AMPLIFY, and A041702) have demonstrated higher rates of undetectable minimal residual disease (uMRD) and longer remissions with triplets than doublets, particularly in patients with IGHV-unmutated (IGHV-U) disease. However, this comes at the cost of increased infectious toxicity, particularly with COVID-19, and thus has translated into a variable impact on progression-free survival (PFS) and, to-date, no overall survival (OS) benefit. Although there are promising Phase 2 data for triplets in patients with TP53 aberrant or relapsed disease, the heterogeneity of treatment duration/MRD definition, lack of control arm, and potential increased toxicity make it premature to use triplets in these groups. We recommend considering triplets in treatment naïve CLL patients with IGHV-U, TP53 wild type, anticipated low incidence/good tolerance of Gr ≥ 3 infection (<70 years old, no major comorbidity and fully immunized) who are well informed and prioritize maximal time off therapy at the expense of increased short-term logistical complexity. Future triplet research should focus on randomized trials in specific genomic subgroups, incorporating novel agents (e.g., non-covalent BTKI, BTK degrader, and next-generation BCL2 inhibitors) and new ways of adapting treatment duration to maximize efficacy and minimize toxicity.}, }

Understanding where SARS-CoV-2 fits, whether it behaves like influenza and dengue or follows an entirely different pattern, is essential for diagnosis, management, and planning long-term care. We conducted a systematic review following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines (PROSPERO: CRD420251064831). Searches across PubMed, Scopus, and Web of Science (2000-2025) identified 24 eligible studies, including observational cohorts, clinical trials, case series, autopsy work, and national surveillance data. Because of the wide variation in study design and reporting, a narrative synthesis was used. Across the 24 studies, COVID-19 exhibited the widest and most severe spectrum of neurological involvement. Reported central nervous system complications included ischemic stroke, encephalopathy or encephalitis, seizures, and extensive microglial and white-matter injury in fatal cases. Peripheral complications were also prominent, such as anosmia, demyelinating neuropathies, Guillain-Barré syndrome (GBS), chronic inflammatory demyelinating polyneuropathy, functional movement disorders, and persistent abnormalities on nerve conduction testing long after recovery. In contrast, neurological complications from influenza were less frequent and mostly involved encephalitis/encephalopathy, seizures, meningitis, GBS, or myelitis, with generally low mortality. Dengue virus has been associated with a spectrum of direct neurotropic effects and immune-mediated syndromes, including encephalitis, GBS, myelitis, brachial neuritis, and myositis. Most patients recovered, and mortality remained low. Compared with influenza and dengue, COVID-19 stands out for both the breadth and severity of its neurological manifestations, as well as the persistence of symptoms in many survivors. These findings highlight the need for early neurological evaluation in COVID-19, structured follow-up after recovery, and more consistent research methods to allow better comparisons across viral infections.}, }

Barriers to care-such as stigma, cost, and limited access in rural areas-mean that many nurses remain untreated. Digital mental health interventions (DMHIs) offer scalable, flexible, and often anonymous support tailored to nurses' schedules and risks. These include teletherapy platforms, AI-driven chatbots and support systems, mobile mental health apps, and hybrid digital-human models. Recent studies (2020-2025) suggest DMHIs can reduce anxiety, depression, and burnout while improving resilience, job satisfaction, and retention. However, obstacles such as unequal access, variable digital literacy, privacy concerns, and limited long-term evidence slow adoption. This review synthesizes current research on DMHI types and efficacy, and examines factors affecting their accessibility and integration into nursing practice.

Intensive care workers and doctors tended to have better knowledge compared with other settings or HCWs. Regarding attitudes, PPE and gatekeeping visitation caused strain, and some HCWs felt that guidance lacked relevance to their setting. Finally, regarding practices, this review found that HCWs would risk assess what PPE to wear. An enhanced level of PPE than advised was worn when patients were symptomatic. However, HCWs would remove PPE when they felt it reduced effective communication or patient safety was at risk. Clearer communication of the evidence behind IPC guidance and tailored guidance for each setting may improve HCWs' KAP and thus reduce HCAIs. Future research should determine KAP of other IPC apart from PPE. Non-medical HCWs should also be included as they constitute a significant proportion of patient-facing staff.}, }

This review synthesizes historical and contemporary evidence across viral, bacterial, fungal, and parasitic threats to characterize how diverse pathogens emerge and spread. Foundational events such as the 1918 influenza pandemic, mid-century influenza pandemics, the emergence of HIV/AIDS, and the eradication of smallpox provide context for understanding modern disease dynamics. In recent decades, coronaviruses including SARS, MERS, and SARS-CoV-2, pandemic H1N1, avian influenza subtypes, and major arboviruses such as dengue, chikungunya, Zika, West Nile virus, and yellow fever have demonstrated the rapidity with which zoonotic pathogens can disseminate globally. Viral hemorrhagic fevers including Ebola, Marburg, Lassa, and Crimean-Congo hemorrhagic fever remain critical threats, especially in regions with limited health-care capacity. Concurrently, antimicrobial resistance, the emergence of Candida auris, and the climate-driven expansion of endemic mycoses involving Histoplasma, Coccidioides, and Blastomyces highlight the increasing importance of fungal pathogens. Parasitic diseases such as artemisinin-resistant malaria, zoonotic trypanosomiasis, and expanding Leishmania transmission reflect shifting ecological conditions. These patterns are shaped by intersecting drivers including deforestation, wildlife trade, agricultural intensification, urban crowding, conflict, and rapid microbial evolution that enable spillover and sustained transmission. Although advances in genomic surveillance, metagenomic diagnostics, mRNA vaccines, monoclonal antibodies, and broad-spectrum antivirals have strengthened global response capacity, substantial gaps persist in equity, surveillance, and access to countermeasures. Strengthening One Health systems and resilient public health infrastructures is essential to anticipate and mitigate emerging infectious threats.}, }

Emerging evidence suggests that MCCIs are on the rise because of the growing use of motorcycles for transport and delivery services, even though road safety overall has improved. We sought to review regional evidence on MCCIs' patterns, key risk factors, and temporal trends to inform policy interventions and research priorities for effective prevention.<br><br>METHODS: A scoping review was conducted in accordance with the PRISMA-ScR guidelines. Articles on GCC MCCIs published from July 2008 to October 2025, examining injury patterns, mortality, and safety practices, were included in the review. Search was conducted across PubMed, Scopus, Google Scholar, and grey literature sources. The GCC consists of six countries: Saudi Arabia (KSA), Qatar, Kuwait, the United Arab Emirates (UAE), Bahrain, and Oman.<br><br>RESULTS: Of 1344 studies identified, 9 met the inclusion criteria and were analyzed. The GCC has seen an increase in the number of motorcycles registered, resulting in higher MCC rates over time. During the COVID-19 pandemic, these rates surged again as the delivery sector grew. MCCI victims were mainly young males (mean age of 29 years). Extremity injuries were the most frequent (two-thirds), followed by head injuries (20-41%), often associated with poor helmet use compliance (range 13-17%). Delivery riders represented a high-risk subgroup, reflecting occupational exposure, fatigue, and time pressure. Despite advances in trauma care, geographic gaps persist. Helmet use non-compliance, alcohol use, and inadequate documentation remain significant risk factors. Extremity injuries were the most common in the GCC.<br><br>CONCLUSION: MCCIs in the GCC are on the rise with high rates of extremity and head trauma. Poor helmet use compliance is a significant factor. Therefore, we suggest strengthening helmet use laws and safety standards, increasing community efforts, and establishing motorcycle lanes with lower speed limits. Protection for riders at work should be enhanced. Road infrastructure and robust data systems also need improvement.}, }

We synthesised evidence on catch-up vaccination strategies and interventions, delivery platforms, uptake and coverage, and contextual barriers and enablers in LMICs.<br><br>METHODS: We searched Embase, Medline, PsycINFO, Global Health, Web of Science and grey literature sources (including websites of international and national public health organisations and agencies) for primary studies and reports on catch-up vaccination strategies and interventions, delivery platforms, uptake and coverage, and contextual barriers and enablers targeting adolescents (9-18&#xa0;years) and, or adults (&#x2265;19&#xa0;years) in migrants (foreign-born, including refugees) and internally displaced people (IDPs; displaced within national borders) across 136 LMICs, (from January 1st 2000 to February 1st 2025; all languages). Study quality was accessed using ROBINS-I, CASP, AACODS and, AGREE II tools.<br><br>RESULTS: Thirty-seven records met the inclusion criteria (13 peer-reviewed, 24 grey literature), reporting catch-up vaccination activities across 16 LMICs. Most studies were conducted in Uganda (n&#xa0;=&#xa0;6), Bangladesh (n&#xa0;=&#xa0;4), Lebanon (n&#xa0;=&#xa0;3), and Kenya (n&#xa0;=&#xa0;3). Interventions reached &#x2265;48,000 migrants, refugees, and IDPs (primarily Rohingya refugees in Bangladesh during COVID-19 catch-up campaigns). Populations targeted included mostly refugees (n&#xa0;=&#xa0;16 studies; 43.2%), general migrants (n&#xa0;=&#xa0;14; 37.8%), and IDPs (n&#xa0;=&#xa0;5; 13.5%), with a smaller number involving mixed or other migrant groups (n&#xa0;=&#xa0;4; 10.8%). The most frequently delivered vaccines were measles-rubella (n&#xa0;=&#xa0;12; 32.4%), COVID-19 primary-series catch-up (n&#xa0;=&#xa0;9; 24.3%), HPV (n&#xa0;=&#xa0;6; 16.2%), polio OPV/IPV (n&#xa0;=&#xa0;5; 13.5%), and Hepatitis B (n&#xa0;=&#xa0;3; 8.1%). Catch-up vaccine delivery most commonly occurred through primary care via opportunistic offers (n&#xa0;=&#xa0;11) and mobile/outreach delivery (n&#xa0;=&#xa0;11), with additional implementation in fixed posts in camps/settlements (n&#xa0;=&#xa0;7), supplemental immunisation activities (SIAs) (n&#xa0;=&#xa0;6), school-linked delivery (n&#xa0;=&#xa0;5), and hospital/outpatient opportunistic vaccination (n&#xa0;=&#xa0;4). High uptake (&#x2265;85%) was reported where access barriers were minimised (e.g., walk-in availability, extended hours) was paired with community or peer engagement and simple recall systems (SMS or e-booking). Reported barriers included documentation/entitlement checks, language barriers, and fragmented or non-interoperable vaccination records.<br><br>CONCLUSIONS: Migrants remain at risk of under-immunisation, and greater emphasis must be placed on promotion of vaccination across the life-course for missed vaccines, doses, and boosters.

No increase in overdose rates was associated with allowing for additional take-home doses of methadone. However, access to treatment, even telehealth, remains difficult for individuals due to a lack of OUD treatment providers and access to the internet. More needs to be done to address the opioid overdose crisis, especially among AI/AN communities. Research focused on cultural strategies to address this health disparity is desperately needed.

TLR agonists have emerged as promising adjuvants to enhance the efficacy of viral vaccines by modulating immune responses, improving antigen presentation, and promoting both humoral and cellular immunity. This review comprehensively summarizes the classification, signaling mechanisms, and immunomodulatory functions of cell-surface and intracellular TLRs. It further discusses the application of TLR agonists as adjuvants in vaccines against major viruses, including HBV, HCV, HIV, SARS-CoV-2, influenza, and flaviviruses. Key findings from preclinical and clinical studies highlight the potential of TLR agonists to overcome immune tolerance, enhance vaccine immunogenicity, and provide broad-spectrum protection. Finally, it points toward the "integration of precision adjuvants with novel vaccine platforms" as a core future direction, laying a theoretical and applied foundation for TLR agonists to become the next generation of viral vaccine adjuvants.}, }

Searches were performed in PubMed through 08/31/2025 with no geographic restrictions. Key study characteristics extracted: country, time period, population, parameters adjusted for underreporting, and the adjustment multipliers used. A high-level quality assessment of evidence was conducted, building on Drummond checklist and CHEERS. Given the qualitative nature of the question and the expected heterogeneity in study designs, the results were summarized qualitatively.<br><br>RESULTS: A total of 20 studies met the inclusion criteria. Of these, 14 (70%) reported numerical adjustment factors, and the remaining 30% did not report a numerical factor. The studies covered diverse geographic regions and time frames, with adjustments applied to parameters such as infections, hospitalizations, and mortality. The study quality was moderate to high. The multipliers used ranged widely across studies: 1 to 5 for mortality, 1 to 5 for hospitalizations, and 1 to 10 for infections, where a value higher than 1.0 reflects an adjustment factor for underreporting. The methodologies used to estimate underreporting varied, including comparisons to excess mortality data, Monte Carlo simulations, and validation against external datasets.<br><br>LIMITATIONS: Most studies used pandemic time horizons.<br><br>CONCLUSIONS: This review identified 14 modelling studies reporting numerical adjustment factors. The studies used diverse approaches and adjustment factors, reflecting variability in data availability and estimation methods. Recognizing and standardizing these adjustments is crucial for improving the accuracy and comparability of health economic analyses that inform policy decisions. Further research could refine underreporting estimates and assess their impact on economic model outcomes.}, }

Recent research has sought to investigate the connection between newly emerged viruses, such as COVID-19, or medications like Anti-Tumor Necrosis Factor Alpha (anti-TNF-&#x3b1;), and the development, progression, and treatment approaches of IgAV in IBD patients, and vice versa. Certain recent research is centered on a particular age groups or the condition of the initial illness. IgAV has been observed for numerous years following the diagnosis of IBD, displaying manifestations in the skin, joints, kidneys, and gastrointestinal tract. IBD encompassing Crohn's disease and ulcerative colitis, and IgAV share immunological overlaps via dysregulated IgA production, genetic loci like HLA-DQA1/DQB1, and environmental triggers such as infections amid gut dysbiosis. IgAV often emerges as an IBD sequela or anti-TNF-&#x3b1; therapy complication, with TNF blockade potentially disrupting B-cell maturation, fostering Gd-IgA1 complexes, and neutrophil-driven inflammation. (31) studies encompassing (83) patients with co-occurring IBD and IgAV, predominantly males (60.2%) and younger individuals with confirmed dual diagnoses (95.2%). Compared to UC, more severe CD phenotypes and extended disease duration correlate with increased IgAV risk. Anti-TNF inhibitors appear to substantially contribute to IgAV onset in IBD patients. Most affected individuals develop IBD initially, followed by IgAV, whereas only a minority experience IBD subsequent to IgAV diagnosis. Ceasing anti-TNF-&#x3b1; therapy post-IgAV diagnosis may lead to IgAV resolution but could also trigger disease recurrence. The study's limited sample size has hindered the researchers from reaching conclusions via a meta-analysis. Additionally, the criteria utilized for IBD diagnosis have displayed inconsistency across all studies. Patients with IBD are at higher risk of developing IgAV, thus a high level of suspicion and prompt diagnostic assessment are crucial. To date, there have been no previous systematic reviews or meta-analyses highlighting a link between IgAV and IBD. Therefore, this systematic review is a pivotal endeavor to elucidate the complex relationship between these conditions, shaping future research in this area.}, }

A deeper understanding of the biology of SARS-CoV-2 was instrumental in facilitating the development of protective vaccines and new therapeutics, as well as evaluating the impact of drug re-purposing to limit the pandemic. To date, approximately 13.64 billion vaccine doses have been administered; with approximately 67% of the global population having completed their primary series of COVID-19 vaccinations. The FDA has authorised the use of several repurposed drugs to combat the disease and while these developments have been instrumental in curbing the pandemic, the approved therapies have shown poor efficacy in cases of severe disease. Furthermore, several vaccine candidates received FDA approval following clinical trials where they proved to be both safe and efficacious. These vaccines were sanctioned for emergency roll-out to the global population, conferring herd immunity and reducing both infections and related mortalities. However, these vaccines are not without flaws and are limited by short term immune responses and poor efficacy against emerging variants, which has resulted in slip-through infections. Hence, efforts to develop potent drugs and vaccines are continuing. In these efforts, physiologically relevant models of SARS-CoV-2 infection are critical.

The organisms implicated in conjunctivitis associated with DED were Coxsackie A24virus, Staphylococcus, and Mycoplasma. There were no immunocompromised patients in any of the studies except HIV. Nine studies established DED diagnosis based on symptoms alone, seven on signs alone, and 12 on symptoms and signs (at least abnormal Schirmer or tear break-up time, but not DEWS II criteria). The severity of DED symptoms was usually mild. HIV and hepatitis C showed no difference in tear volume and stability between cases and healthy controls. Advanced stages of hepatitis (stage 4 to stage 6) showed worse tear film parameters than the initial stages. Tear volume and stability were affected in 1/5th of patients post-COVID-19. Absolute tear deficiency (zero Schirmer) was reported in two patients after Epstein-Barr virus and HIV infection that improved with intravenous acyclovir, cyclosporin A, and prednisolone in EBV infection only. Very few studies reported the management of postinfectious DED with artificial tears and had fair outcomes.<br><br>CONCLUSION: Bacterial and viral infections can have DED as sequelae, although the infectious agent has not been isolated from the ocular surface in reported studies. DED is usually mild to moderate symptomatically, and tear film parameter levels do not meet DEWS II diagnostic criteria.

The viruses responsible for these outbreaks, such as SARS-CoV, MERS-CoV, Zika, Ebola, Nipah, avian influenza, and, most recently, SARS-CoV-2, typically originate in wildlife, highlighting the complex relationship between ecological systems and human activities. Human-wildlife interactions have markedly increased due to disruptions in environmental and geographic boundaries, primarily driven by urbanization, deforestation, intensified agricultural practices, and climate change. These factors contribute to an environment that facilitates zoonotic transmission spillover. This narrative review summarizes current research on the ecological, geographic, and human factors influencing zoonotic virus transmissions. It emphasizes how these viruses adapt to human hosts and cross species barriers via direct contact, vector-borne transmission, intermediate carriers, and environmental contamination. Moreover, the review discusses how the genomic plasticity of viruses enhances their transmissibility and facilitates adaptation to new hosts, thereby increasing the risk of epidemics and pandemics. The review further underscores the importance of ecological boundaries in mitigating spillover events and advocates for a One Health approach that integrates human, animal, and environmental health. This approach is essential for predicting, detecting, and preventing future outbreaks. In conclusion, the review emphasizes the importance of interdisciplinary research, proactive surveillance, habitat preservation, and policy interventions that address the underlying ecological factors contributing to zoonotic outbreaks. Restoring ecological barriers and implementing sustainable practices to minimize the interaction between wildlife and humans, while bolstering global biosecurity, are essential measures to mitigate the risk of future pandemics.}, }

Yet, large-scale production and purification of such complex proteins remain costly and can restrict patient access. A promising alternative is to improve in vivo expression capabilities, which will reduce manufacturing burdens and improve safety and tolerability. Multiple gene delivery platforms - ranging from mRNA and viral vectors to engineered cell therapies - have matured considerably, as a direct result of years of clinical experience and growing regulatory confidence. The rapid deployment of mRNA vaccines against SARS-CoV-2, the clinical success of adeno-associated virus (AAV)- and lentiviral-based interventions, and the approval of chimeric antigen receptor (CAR)-T cell therapies highlight the potential of these technologies to transform how we deliver Ab therapeutics. While these approaches hold the promise to treat genetic aberrations in patients, they may also contribute considerably to advancing conventional Ab therapeutics against viral infections and other diseases through local persistence of the proteins. Looking forward, in situ expression may confer even more benefits for engineered Ab-like molecules, thereby compensating for possibly shorter half-lives and overcoming challenges in in vitro production and purification. Therefore, in this review, we critically evaluate how these established and emerging gene therapy platforms can be harnessed to expand access, and discuss possibilities to improve in situ availability through the choice of transient or stable expression systems to increase the efficacy of Abs and other therapeutic proteins. Furthermore, we explore the current landscape of technological advancements, identify key translational challenges, and project future directions for optimizing these approaches towards widely applicable clinical interventions.}, }

MDA5 functions as a cytoplasmic sensor for viral double-stranded RNA. The expression level of anti-MDA5 antibodies is positively correlated with disease severity.

Various supervised, unsupervised, deep learning, and time-series models were compared based on their predictive accuracy, scalability, interpretability, computational demands, and real-time feasibility. Comparative analysis showed that Random Forest (RF) achieved R[2] values of 0.80 and Root Mean Square Error (RMSE) 0.54 for COVID-19 trend forecasting, outperforming linear regression. Support Vector Machines (SVM) improved pathogen classification accuracy by ∼20% compared with traditional analytical techniques. Artificial Neural Networks (ANN) estimated pathogen prevalence with R = 0.81-0.92 and mean squared, while Long Short-Term Memory (LSTM) networks achieved R[2] ≈ 0.81 (test) and 0.94 (train) for multi-community forecasting.

A systematic review and meta-analysis were conducted. Two researchers independently screened the literature, extracted data, and assessed methodological quality. The pooled mean score was calculated using random-effects or fixed-effects models, with subgroup analysis to explore heterogeneity.Ethical considerationsEthical approval was not required as the review synthesized publicly available data.ResultsThis study included 16 articles, involving 5824 participants. The meta-analysis showed that the pooled mean total MISS-HP score for nurses was 42.12 (95% CI: 40.70-43.53). Among the dimensions, the pooled mean score for Loss of religion/spiritual faith was the highest at 5.68 (95% CI: 4.61-6.74), while the pooled mean score for religious struggles was the lowest at 2.26 (95% CI: 1.13-3.40).

During the early months of the COVID-19 pandemic, symptoms of anxiety and depression became more prevalent, and many mental health services were compromised by pandemic-related factors; however, whether the COVID-19 pandemic accelerated pre-existing long-term trends of increasing incidence of mental health disorders, especially in children and adolescents, is unclear. Little research has been done in low-income and middle-income countries, or regarding post-COVID-19 condition (also known as long COVID), which emerged as a multisystem condition with mental health implications. Vulnerable populations, including socioeconomically disadvantaged and minoritised groups, faced disproportionate mental health impacts and limited access to care during the COVID-19 pandemic, reflecting systemic, pre-pandemic inequalities. Bold implementation of existing evidence-based mental health support for vulnerable communities, ambitious trials of novel interventions, and systematic pooling of rapidly accumulating evidence about best healh care should be priorities in future pandemics.}, }

Guided by four questions relating to system adaptations, approaches to inequities, financing strategies, and evidence gaps, we synthesised evidence from a structured literature search (2020-24), expert consultation, and lived experience. We found that public health systems embedded infodemic management, expanded digital services, and mobilised community workforces, but responses varied in equity and effectiveness. Although gender, age, socioeconomic, and racial disparities worsened during the COVID-19 pandemic, social protection, gender-sensitive policies, school-based services, and culturally adapted interventions showed promise. High-income countries buffered shocks with welfare measures while low-income and middle-income countries faced sharp fiscal constraints. Few studies evaluated cost-effectiveness or equity impacts of psychosocial interventions. Building resilient, equitable mental health systems requires integrated policies spanning communication, digital and community care, gender-responsive and youth-responsive strategies, and sustainable financing, alongside investment in longitudinal and cross-national research.}, }

Among multiple implementations of this technology, pulsatile oxygen saturation (SpO2) is a core medical technology and is being rapidly adopted in consumer health. However, despite its long history of clinical use, recent findings indicate that the accuracy of pulse oximetry may be affected by various factors and biases. For example, the COVID-19 pandemic showed that pulse oximeters exhibited flaws in accuracy due to the skin pigmentation of patients with darker skin. Thus, the future of this technology, particularly in consumer health devices, needs to be built on foundations that account for such biases. This chapter reviews the principles of pulse oximetry, sources of its artifacts, calibration methods, and the factors that may cause inaccuracy in pulse oximeters, particularly pertinent to two-wavelength pulse oximetry. Drawing upon recent research and clinical insights, we review the multifaceted nature of pulse oximetry biases, including motion artifacts, skin pigmentation, body mass index, environmental variables, device calibration, and nail polish, among others.}, }

The search was conducted in October 2024 on PubMed, Scopus, and Web of Science. Reviews published in English between the years 2009&#x2013;2024, reporting data on COVID-19, H1N1, influenza or seasonal flu, measles, or Mpox, and documenting gaps or challenges in the response to these outbreaks at healthcare facility level were included.<br><br>RESULTS: A total of 21 reviews were included: they were systematic, scoping, narrative, rapid, or integrative. The studies included in the reviews were mostly conducted in the United Kingdom, Italy, Spain, and France. The studies included different levels of healthcare facilities, namely hospitals, primary healthcare, and prehospital settings. Findings were classified according to the 4S surge capacity framework and were related to staff (n&#x2009;=&#x2009;18), stuff (n&#x2009;=&#x2009;14), space (n&#x2009;=&#x2009;7), and system (n&#x2009;=&#x2009;18).

Mechanisms are multifactorial, involving ACE2-linked epithelial/neuromuscular effects, persistent low-grade inflammation, microbiota dysbiosis with reduced short-chain fatty acids, altered serotonin signaling, barrier dysfunction, and psychosocial stress acting along the gut-brain axis. Emerging data indicate dyspnea and depression further mediate the COVID-19-to-IBS pathway, underscoring biopsychosocial endotypes.<br><br>CONCLUSIONS AND INFERENCES: This review indicates that following infection with SARS-CoV-2, DGBI, particularly IBS, occurs in 7.2% patients on follow-up.

Brain computed tomography (CT) revealed bilateral occipital diffuse hypodensity. Throughout her hospitalization, she exhibited elevated blood pressure necessitating intravenous treatment. The initial brain MRI revealed T2-weighted image hyperintensity at the parietal and occipital levels, indicative of vasogenic edema. These neuroimaging findings were suggestive of posterior reversible encephalopathy syndrome (PRES). Euvolemic hyponatremia with concurrent low serum osmolality and high urine osmolality and sodium was observed, indicating a syndrome of inappropriate antidiuretic hormone (SIADH). Throughout the patient's stay, her level of consciousness exhibited significant improvement. However, she developed ascending symmetrical limb weakness and progressive loss of reflexes, along with a severe motor deficit and gait disturbance, accompanied by arterial blood pressure fluctuations and other signs of autonomic dysfunction. Clinical manifestations, neurophysiological findings, and laboratory results were indicative of Guillain-Barre Syndrome (GBS), leading to a conclusive diagnosis of GBS with dysautonomia triggered by a COVID-19 infection.<br><br>CONCLUSION: This case reveals the relevance of diagnosing autonomic dysfunction (including PRES) as the initial manifestation of GBS linked to COVID-19 infection and the importance of early diagnosis to prevent potential complications.}, }

Currently classified as a Category 5 virus (for which medical institutions and individuals primarily implement preventive measures independently, without significant administrative intervention such as isolation), COVID-19 infections continue to peak biannually, currently driven by the Nimbus variant, a derivative of the Omicron strain. This situation necessitates ongoing vigilance in infection prevention efforts. While it is well-established that environmental factors, such as proper ventilation, are crucial in mitigating the risk of COVID-19 transmission, it has become evident that variations in individual susceptibility exist; some individuals contract the virus while others do not, even in identical environments. Personal factors, including pre-existing medical conditions, influence this disparity. This narrative review examines personal factors related to general health assessments within the workplace, incorporating data from systematic reviews and meta-analyses, as well as insights from both international and domestic academic societies. Although the strength of evidence varies, factors such as male gender, smoking, alcohol consumption, obesity, inadequate sleep, insufficient physical activity, hypertension, hyperlipidemia, diabetes, and chronic obstructive pulmonary disease have been identified as contributors to the severity and onset of COVID-19, as well as its associated mortality.}, }

This meta-analysis evaluates the protective role of BCG vaccination in preventing COVID-19 among healthcare workers (HCWs). A systematic review and meta-analysis were conducted of randomized controlled trials (RCTs) that reported the effect of BCG vaccination for COVID-19 prevention in HCWs compared with placebo. Nine RCTs were included, with a total of 10,295 HCWs. Pooled odds ratios (ORs) and mean differences (MDs) were calculated using random- and fixed-effects models to assess the impact on symptomatic COVID-19, severe disease, hospitalization, seropositivity, duration of illness, and serious adverse events. Heterogeneity was evaluated using I[2] statistics. BCG vaccination did not significantly reduce the risk of symptomatic COVID-19 (OR = 1.05, 95% CI: 0.94-1.17, p = 0.43, I[2] = 47%), severe COVID-19 (OR = 1.20, 95% CI: 0.97-1.48, p = 0.09, I[2] = 0%), or hospitalization (OR = 1.04, 95% CI: 0.71-1.50, p = 0.86, I[2] = 0%).

Viral fusion glycoproteins are prominent antigens on the surface of virions and are essential for the virus life cycle. Therefore, they are a primary target for the humoral immune system and the basis for the design of vaccines. Antibodies which target viral fusion glycoproteins can neutralize viral infectivity and activate the immune system in several distinct ways.

Leading journals included Frontiers in Immunology, PLoS ONE, and Scientific Reports. The United States produced the largest share of publications, followed by Canada and Spain, with notable contributions from the University of British Columbia and Université de Montréal. Influential authors such as Côté HCF, Pick N, and Maan EJ have advanced research, particularly in the areas of HIV and tuberculosis. Keyword analysis highlighted two dominant themes: immune ageing and infection-related stress. Malaria research was comparatively scarce, underscoring a gap for future investigation.

It was conducted in accordance with PRISMA guidelines, and the study protocol was registered in PROSPERO (CRD420251179614). A total of 38 studies published between 2020 and 2025 were analyzed, involving more than 20,000 participants from various countries. Most studies were cross-sectional, although some longitudinal and quasi-experimental studies were also included. The results showed a consistent association between higher levels of physical activity and lower levels of stress, depression, and anxiety, as well as an increase in subjective wellbeing. In addition, mediators such as sleep quality and resilience, and moderators such as gender or internet use, were identified. The effects were more significant when physical activity was combined with other healthy habits such as good sleep and low sedentary behavior. Although most of the studies were not experimental, the evidence suggested a possible beneficial causal effect of exercise. The need for comprehensive interventions in universities was highlighted, promoting physical activity as a preventive and therapeutic strategy to improve the mental health of students.

The widespread administration of the COVID-19 vaccine has further accelerated research into the precise therapeutic potential of mRNA technologies. Since mRNA doesn't integrate with the host genome, the safety and versatility of mRNA-based therapeutics make them an iconic candidate in targeted therapies. Due to a surge in innovation efforts, biomodification of the molecular signatures of mRNAs like the 5'cap, untranslated regions (UTRs), and the poly(A) tail are being developed to increase translation efficacy. Recent advancements in chemical modifications, codon optimization techniques, and targeted delivery methods have significantly enhanced the stability of synthetic mRNAs while concurrently reducing their immunogenicity. Various mRNA manufacturing and synthesizing methods are investigated in this review, focusing on their scalability and limitations. mRNA therapeutic strategies can be divided into protein replacement, immune modulation, and cellular modulation.

However, the efficacy of CP from COVID-19 patients remains controversial and uncertain based on current randomized controlled trials (RCTs). There is an urgent need to establish the efficacy and safety of CP for COVID-19 patients as soon as possible.<br><br>OBJECTIVE: To verify the efficacy and safety of CP using high-quality, double-blinded, parallel-arm, placebo-controlled randomized clinical trials, and to provide evidence-based support for the clinical application of CP against COVID-19.<br><br>METHODS: Electronic databases such as Embase, PubMed, and Web of Science were searched from inception to October 18, 2024. This meta-analysis synthesized dichotomous outcomes, including 28-day mortality, hospitalization rates, invasive mechanical ventilation, adverse events (AEs), and serious AEs, using an intention-to-treat (ITT) analysis. Statistical analysis was performed using Review Manager (RevMan) 5.4.1, the Mantel-Haenszel (M-H) statistical method, and a random effects (RE) analysis model. Risk ratios (RRs) and their 95% confidence intervals (CIs) were used as effect measures. Two reviewers independently searched, screened, and included eligible clinical trials, extracted relevant data, and assessed risks of bias (ROB) using the Cochrane ROB tool 1.0 and RevMan 5.4.1. The RRs and 95% CIs in this meta-analysis were computed as dichotomous outcomes. Statistical heterogeneity, subgroup analysis, and sensitivity analysis were conducted to explore heterogeneities and their causes. The quality of evidence was evaluated, and recommendations for clinical practice were based on the GRADE approach. The prospective meta-analysis protocol was registered on PROSPERO.<br><br>RESULTS: A total of 996 references were identified through database and manual searches. Nine eligible double-blinded, parallel-arm, placebo-controlled randomized clinical trials, involving 1898 subjects in the intervention group and 1696 in the control group, were included in the meta-analysis. Seven, four, three, three, and three trials were judged as low ROB for mortality, hospitalization rates, invasive mechanical ventilation, AEs, and serious AEs, respectively. The remaining trials were deemed high-risk for their respective outcomes. The meta-analysis on hospitalization rates was abandoned due to high heterogeneity (I&#xb2;=92%) among the included trials. The RRs, 95% CIs, and P-values were as follows: 0.78 [0.62, 0.97], P&#x2009;=&#x2009;0.03 for mortality; 0.84 [0.50, 1.42], P&#x2009;=&#x2009;0.51 for invasive mechanical ventilation; 1.01 [0.78, 1.32], P&#x2009;=&#x2009;0.92 for AEs; and 0.96 [0.73, 1.28], P&#x2009;=&#x2009;0.80 for serious AEs, all with low or medium levels of heterogeneity. These results suggest that CP infusion in COVID-19 patients reduced mortality by 22% and exhibited excellent safety without reducing the incidence of invasive mechanical ventilation. Sensitivity analysis on mortality, using the combined effect measure (RR 0.83 [0.66, 1.06], I&#xb2;=0%, Z&#x2009;=&#x2009;1.46, P&#x2009;=&#x2009;0.14) after excluding the study by O'Donnell, showed no significant difference between the intervention and control groups, implying that the excluded study might have a stronger effect in reducing mortality.

However, its role in long-term service models, equity, and health-system performance remains incompletely defined. This narrative review aimed to provide an up-to-date synthesis of the evidence on teledentistry across clinical specialties, populations, and settings, and to discuss implications for practice, policy, and future research. Electronic databases were searched from inception to December 2025 for studies evaluating teledentistry or related digital remote dental services. Eligible sources included observational and interventional studies, reviews, economic evaluations, implementation reports, and key professional or policy documents. Data were organized thematically around clinical effectiveness, patient and provider experience, cost and resource use, equity and access, regulatory frameworks, and emerging technologies. Across settings, teledentistry supports accurate diagnosis and triage for selected indications, particularly in orthodontics, pediatric dentistry, and community-based screening. Most studies report gains in access, reduced need for travel, and high levels of patient satisfaction, especially in rural, institutionalized, and otherwise underserved groups. Evidence for long-term clinical outcomes, cost-effectiveness, and the impact on oral-health inequities is promising but remains heterogeneous and often limited by small samples, short follow-up, and methodological constraints. Successful programs depend on reliable infrastructure, integration with electronic records, clear clinical protocols, appropriate training, and supportive legal and reimbursement frameworks, while concerns persist about data protection, medico-legal responsibility, and the potential for digital services to widen rather than narrow gaps between population groups. Overall, teledentistry should be viewed as a component of planned hybrid oral healthcare models rather than a substitute for in-person care. Future work needs pragmatic comparative studies, robust economic analyses, and equity-focused evaluations. Under these conditions, teledentistry has the potential to contribute meaningfully to more accessible, continuous, and person-centered oral healthcare.}, }

TeleSRH use declined since the COVID-19 pandemic's peak but remains higher than pre-pandemic. Evidence comes mostly from poor-quality studies. TeleSRH increases access and adherence to STI prevention (e.g., pre-exposure prophylaxis for HIV). Tele-follow-up may safely facilitate HIV care continuity. For CC/FP, TeleSRH is comparable to in-person care for patient satisfaction and uptake; patients are less likely to select long-acting reversible contraception but post-initiation tele-follow-up may increase its continuation rates. Vasectomy completion rates may be similar between pre-procedural counseling via telehealth versus in-person. TeleSRH's potential benefits might include reduced travel time, wait times, no-show rates, and clinic human resource burden (via tele-triaging) and increased preventative screening rates for STIs and non-communicable diseases, prescription refill rates, ability to receive confidential care in preferred settings, and rural/marginalized community outreach. Implementation challenges span technological and capital constraints, provider availability, staff capability building, restrictive policies, language incompatibility, and patient mistrust.

Their strong antimicrobial activity and chemical stability make them valuable in applications but also highly persistent and toxic when released into aquatic environments. This problem has become increasingly relevant during and after the COVID-19 pandemic, when global use of QAC-based disinfectants increased drastically, resulting in their frequent detection in municipal, hospital, and industrial effluents. The concentrations of QACs reported in wastewater range from trace levels to several mg/L, often reaching inhibitory thresholds for biological treatment processes. Although surfactants are not listed in any current European directive, the revised Directive (EU) 2024/1440 classifies micropollutants as a priority group, imposing stricter environmental quality standards and mandatory monitoring requirements. Within this regulatory framework, QACs are recognized as compounds of emerging concern, and their effective removal from wastewater has become a critical challenge. This review summarizes the current knowledge on conventional treatment technologies (coagulation, adsorption, ion exchange, advanced oxidation, and biological processes) and membrane-based methods (ultrafiltration, nanofiltration, reverse osmosis, forward osmosis, and hybrid systems) for the removal of cationic surfactants from water and wastewater.

Because early identification of individuals at risk for severe illness is essential, this study systematically evaluated the association between thyroid dysfunction and COVID-19 severity. A comprehensive search of major databases identified 4260 records, of which 13 observational studies met the eligibility criteria, yielding a total of 2829 patients from diverse geographical regions. Mild, moderate, and non-ICU patients were categorized as the non-severe group, while the severe-to-critical group included patients classified as severe or critical, those requiring ICU admission, or hospitalized in dedicated COVID-19 wards according to the criteria used in the original studies. The pooled analysis demonstrated that total and free triiodothyronine (TT3 and FT3) levels were consistently lower in patients with more severe disease, and thyroid dysfunction was associated with 4.8-fold higher odds of severe-to-critical COVID-19. Although thyroid-stimulating hormone (TSH) levels were reduced in patients with COVID-19 compared with non-infected individuals, TSH alone did not predict disease severity. Higher TT3 and FT3 concentrations were consistently associated with a milder clinical course. These findings suggest that thyroid function tests may provide useful prognostic information in patients with COVID-19. The observed hormonal patterns may reflect alterations along the hypothalamic-pituitary-thyroid axis; however, this interpretation remains hypothetical and requires confirmation through studies incorporating direct pituitary hormone assessment.

Both of these conditions also increased during the COVID-19 pandemic. The purpose of this systematic review was to describe how the association between food insecurity and GBV across multiple global regions during the COVID-19 pandemic impacted women. The review aims to inform equity-driven interventions and policy development in the event for use during future emergency crises.<br><br>METHODS: The social-ecological model (SEM) and the intersectionality framework were the frameworks used for this systematic review. The PRISMA guidelines guided this systematic review methodology. The literature search was conducted using the APA PsycINFO, CINAHL, MEDLINE, PubMed, and Web of Science databases in November 2025. The inclusion criteria were as follows: (1) studies conducted during the COVID-19 pandemic; (2) studies that assessed the association between food insecurity and GBV among women during the COVID-19 pandemic; and (3) studies published in English in peer-reviewed journals. The exclusion criterion was any study that was not primary research. The Quality Assessment Tool for Studies with Diverse Designs (QATSDD) was used for quality appraisal. Thematic analysis, guided by Hennink and colleagues (2020), was used to synthesize the results.<br><br>RESULTS: Thirty-two studies were included in the data analysis. At the individual level, food insecurity and GBV during the COVID-19 pandemic were associated with a greater likelihood of reporting mental health conditions such as anxiety and depression. Additionally, being an immigrant was associated with a high risk of experiencing food insecurity and GBV. At the relationship level, food insecurity and GBV were associated with household instability and family dysfunction. At the community level, the association was influenced by poverty and limited employment opportunities. At the societal level, restrictive COVID-19 policies and prevailing cultural norms contributed to intensifying food insecurity and GBV.<br><br>CONCLUSION: This study offers support for strengthening crisis&#x2012;response systems across socio-ecological levels that incorporate gender-sensitive food security and violence prevention strategies during public health emergencies.

A broad range of in silico, cryoelectron microscopy and physicochemical approaches indicate that the RBD becomes accessible after a ganglioside-induced conformational rearrangement originating in the N-terminal domain (NTD) of one protomer and propagating to the neighboring RBD. We previously identified a triad of amino acids, Q134-F135-N137, as a strictly conserved element on the NTD. In the present review, we integrate a series of structural and experimental data revealing that this triad may act as a conformational transducer connected to a chain of residues that are capable of transmitting an internal conformational wave within the NTD. This wave is generated at the triad level after physical interactions with lipid raft gangliosides of the host cell membrane. It propagates inside the NTD and collides with the RBD of a neighboring protomer, triggering its unmasking. We also identify a chain of aromatic residues that are capable of controlling electron transfer through the NTD, leading us to hypothesize the existence of a dual conformational/quantum wave. In conclusion, the complete conservation of the Q134-F135-N137 triad despite six years of extensive NTD remodeling underscores its critical role in the viral life cycle. This triad represents a potential Achilles' heel within the hyper-variable NTD, offering a stable target for therapeutic or vaccinal interventions to disrupt the conformational wave and prevent infection.

Initially developed for epilepsy, VNS has since been applied to treat resistant depression, stroke recovery, and inflammatory conditions. Transcutaneous VNS (tVNS) now offers a noninvasive alternative, fueling clinical trials in disorders ranging from rheumatoid arthritis and migraines to long COVID-19. Mechanistic studies suggest that afferent and efferent vagal fibers modulate immune responses, mood regulation, and neurotransmitter systems. The SPARC initiative has accelerated mapping of vagal circuits, enabling more precise approaches to stimulation. Despite progress, the results remain mixed: while some patients experience lasting symptom relief, others respond no better than to placebo. Depression studies, in particular, highlight both the promise and the complexity of VNS, as inflammation, motivation circuits, and gut-brain signaling emerge as key modulators. Next-generation closed-loop devices and circuit-specific targeting may improve efficacy and reduce adverse effects. VNS research thus lies at the intersection of neuromodulation, psychiatry, and immunology-offering hope for hard-to-treat conditions, yet demanding rigorous trials to separate myths from medicine.

Eligibility criteria included the English- and Russian-language literature published from 1998 onwards, focusing on nine post-Soviet states. Sources of evidence comprised searches in Google Scholar, ScienceDirect, SSRN, Heliyon, MEDLINE/PubMed, and official government websites. Data were charted by three independent reviewers using a standardized form, with discrepancies resolved by senior reviewers. The review identifies persistent gaps in communication during health crises, with a particular focus on the COVID-19 pandemic, where centralized and hierarchical information flows often undermine transparency and responsiveness, as well as further increased health inequalities between rural and urban health outcomes. Despite ongoing reforms, the communication dimension of healthcare systems remains underdeveloped. Findings reveal that centralized and top-down communication remains a dominant feature across the region, hindering timely dissemination of information and limiting the capacity to counter misinformation, as both misinformation and disinformation sometimes emerge from the government. Ultimately, this review contributes a critical analysis of these systematic communication failures and underscores the need to strengthen public health communication and reduce health inequalities. To do it, governments must prioritize transparency, disclose decision-making processes, and rely on evidence-based messaging to build trust. Effective crisis response requires not only government leadership but also the active engagement of the medical and patient communities, supported by civil society and independent media. This review points out the need for more inclusive, transparent, and trust-oriented communication strategies to enhance public health preparedness and resilience in nine Eastern European and Central Asian contexts.}, }

A central focus is the host cellular response to the viral infection, with particular emphasis on the role of cytokines. Cytokines play a dual role in antiviral defense: they contribute to the inhibition of viral replication and facilitate the clearance of pathogens, yet dysregulated cytokine responses can result in severe immunopathology. Interferons (type I, type II, and type III) and other cytokines are pivotal in activating intracellular antiviral mechanisms and in orchestrating the recruitment of immune cells through extracellular signaling. Effective immune responses to viral infections are governed not only by primary immune cells-such as dendritic cells, T lymphocytes, and B lymphocytes-but also by the local cytokine milieu shaped by infected and neighboring cells. Given the presence of endogenous inhibitors and autoantibodies in vivo, it is essential to evaluate the functional activity of cytokines in clinical samples.

In this paper, we summarize the most recent current evidence on how the spike protein structurally evolves, on changes in key non-structural proteins, such as nsp14, and on host factors, such as TMPRSS2 and neuropilin-1. These changes, together, shape viral entry, replication fidelity and interferon antagonism. Given the emerging Omicron variants of SARS-CoV-2, recent articles in the literature, cryo-EM analyses, and artificial intelligence-assisted mutational modeling were analyzed to infer and contextualize mutation-driven mechanisms. It is through these changes that the virus adapts and evolves, such as optimizing angiotensin-converting enzyme binding, modifying antigenic surfaces, and accumulating mutations that affect CD8[+] T-cell recognition. Multi-omics data studies further support SARS-CoV-2 pathogenesis through convergent evidence linking viral adaptation to host immune and metabolic reprogramming, as occurs in myocarditis, liver injury, and acute kidney injury. By integrating proteomic, transcriptomic, and structural findings, this work presents how the virus persists and dictates disease severity through interferon antagonism (ORF6, ORF9b, and nsp1), adaptive immune evasion, and metabolic rewiring. All these insights underscore the need for next-generation interventions that provide a multidimensional framework for understanding the evolution of SARS-CoV-2 and guiding future antiviral strategies.}, }

Most studies focus on acute illness or mixed-age cohorts, with limited data specific to children aged 0-12 years. Objectives: This study aimed to systematically identify, evaluate, and synthesise evidence on post-acute (≥30 days) and long-term (≥90 days) kidney outcomes following SARS-CoV-2 infection or MIS-C in children aged 0-12 years, including chronic kidney disease (CKD), eGFR decline, proteinuria, haematuria, hypertension, and need for kidney replacement therapy. Methods: We searched MEDLINE, Embase, CINAHL, and PubMed (December 2019-30 November 2025), following PRISMA 2020 guidelines and a registered PROSPERO protocol (CRD420251241949). Observational studies reporting kidney outcomes ≥30 days post-infection in children aged 0-12 years were included. Risk of bias was assessed using the Newcastle-Ottawa Scale or ROBINS-I. Owing to heterogeneity and absence of ≥3 comparable datasets, a narrative synthesis was performed. Results: Seven studies met inclusion criteria (five MIS-C cohorts, two acute COVID-19 cohorts). Only a subset provided extractable data specific to children aged 0-12 years. Follow-up ranged from 30 days to 12 months; four studies reported outcomes ≥ 180 days. Across all studies, no incident CKD, sustained eGFR decline, or kidney replacement therapy were reported among children completing long-term follow-up; however, most long-term outcome data were derived from MIS-C cohorts with median ages around 8-11 years that included some adolescents, rather than exclusively children aged 0-12 years. One MIS-C study reported long-term hypertension in 14% of children. A cross-sectional Italian cohort of mild COVID-19 demonstrated hyperfiltration, proteinuria, and microhaematuria at ~3 months, though chronicity could not be assessed due to absence of baseline values. A large US EHR-based cohort identified increased CKD risk after COVID-19 in the broader < 21-year population; however, 0-12-year-specific event counts were not reported, preventing quantitative synthesis for young children. Conclusions: Evidence on long-term kidney outcomes after SARS-CoV-2 infection in children aged 0-12 years remains limited, and only a small subset of studies provided extractable, age-specific data. On the other hand, MIS-C cohorts generally show favourable renal recovery, small sample sizes, lack of control groups, and short follow-up restrict confidence in these findings. Large paediatric EHR studies suggest potential long-term renal risk in broader paediatric populations, highlighting the need for age-stratified, prospective cohorts with serial eGFR, urine studies, and blood pressure assessments. Until definitive evidence emerges, structured renal follow-up may be warranted for children with AKI or MIS-C during COVID-19.}, }

Parents of children with NDDs face a complex socio-emotional reality. They may experience high levels of stress, fatigue, depression, and feelings of guilt and uncertainty, and they are often left feeling isolated and unsupported. All of these factors increase their socio-emotional vulnerability and affect their children's wellbeing. A significant part of the available evidence has focused on parents of typically developing children or on a single construct. For these reasons, and considering the impact of the COVID-19 pandemic, the aim of this study was to review interventions targeting the improvement of the socio-emotional wellbeing of parents of children with NDDs, in order to characterise recent research, the specific constructs addressed, and the effectiveness of interventions. Methods: No prior protocol/registration. ERIC and Web of Science databases (selected for their broad multidisciplinary coverage in psychology and social sciences) were searched from 2020-2025 (last search: 7 September 2025), limited to English/Spanish publications. Inclusion criteria encompassed parents/primary family caregivers of children with NDDs receiving socio-emotional programs. Two independent reviewers screened the titles/abstracts and full texts, resolving disagreements through discussion. Following PRISMA 2020 guidelines, this systematic review employed narrative synthesis without risk-of-bias assessment and included 16 studies (approximately, 1100 participants). Results: The analysis indicated a scarce but growing scientific output, with a complex methodological landscape showing promising preliminary convergence in intervention outcomes. Interventions effects appeared mediated by cultural suitability, accessibility, and contextual alignment.

Following the success of COVID-19 mRNA vaccines, mRNA-based cancer vaccines targeting melanoma antigens have emerged as a promising therapeutic direction. This review summarizes current evidence on mRNA melanoma vaccines, focusing on two leading delivery platforms: lipid nanoparticles (LNPs) and dendritic cell (DC) vaccines. A comprehensive search of MEDLINE, Embase, and Scopus from 2015 to 2025 identified clinical trials, preclinical studies, and review articles evaluating mRNA vaccine constructs and delivery strategies. Completed clinical studies demonstrate that personalized LNP-formulated mRNA vaccines can enhance neoantigen-specific T-cell responses and improve recurrence-free survival, particularly when combined with immune checkpoint inhibitors. DC-based mRNA vaccines also show potent immunogenicity, with stronger responses observed when DC maturation is optimized. Ongoing trials continue to investigate next-generation LNP formulations, DC priming strategies, and personalized neoantigen approaches. Overall, current evidence indicates that both LNP and DC platforms can augment antitumor immunity by broadening T-cell responses and enhancing checkpoint inhibition. Continued refinement of delivery vehicles, neoantigen selection, and scalable manufacturing processes will be essential to realizing the full clinical potential of mRNA vaccines in melanoma.}, }

Severe Acute Respiratory Syndrome CoronaVirus 2 (SARS-CoV-2) may gain access from the nasal cavity to the brain (neurotropism), and the olfactory route has been proposed as a peripheral site of virus entry. COVID-19 is a risk factor for developing Alzheimer's Disease (AD), an age-dependent and progressive neurodegenerative disorder characterized in affected patients by early olfaction dysfunction that precedes signs of cognitive decline associated with neurodegeneration in vulnerable brain regions of their limbic system. Here, we summarize the recent literature data supporting the causal correlation between the persistent olfactory deterioration following SARS-CoV-2 infection and the long-delayed manifestation of AD-like memory impairment. SARS-CoV-2 infection of the olfactory neuroepithelium is likely to trigger a pattern of detrimental events that, directly and/or indirectly, affect the anatomically interconnected hippocampal and cortical areas, thus resulting in tardive clinical dementia. We also delineate future advancement on pharmacological and rehabilitative treatments to improve the olfactory dysfunction in patients recovering even from the acute/mild phase of COVID-19.

Interstitial lung disease (ILD) is the major long-term complication of COVID-19 disease leading to progressive lung fibrosis and reduced respiratory function. The aim of this narrative review is to provide an updated overview of post-COVID-19 ILD by examining research publications and clinical guidelines selected from PubMed, Web of Science, and major respiratory medicine journals from 2020 to 2025. Methods: ILDs are diagnosed by medical history, physiological examination, pulmonary function tests, and chest X-ray or high-resolution computed tomography (HRCT) scan. Lung biopsy, especially cryobiopsy or video-assisted thoracoscopic (VATS) biopsy, can be performed to define histological patterns and confirm the diagnosis. Results: Post-COVID-19 ILD is a chronic condition characterized by long-term respiratory symptoms, radiological findings, and reduced lung function. Fibrotic injury is a consequence of the initial infection and could be influenced by persistent inflammation and dysregulated tissue repair. Risk factors include severe acute illness, advanced age, male sex, and smoking. Clinical course and prognosis of post-COVID-19 ILD is uncertain, as most patients experience gradual improvement or stability, whereas others develop progressive lung function decline. Treatment of post-COVID-19 ILD is not presently defined by guidelines but comprises corticosteroids, antifibrotics (including new drugs such as nerandomilast), supportive oxygen, pulmonary physiotherapy rehabilitation, smoking cessation, and vaccination. Conclusions: ILD represents a significant long-term complication of COVID-19 infection. Further investigations are required to better understand its pathophysiology and clinical management. As research progresses, more effective diagnostic and therapeutic strategies are expected to emerge.}, }

This family belongs to the order Nidovirales and is divided into four main genera: α-CoV, β-CoV, γ-CoV and δ-CoV. It is particularly noteworthy that representatives of β-CoV have caused serious epidemics in humans, such as the outbreaks of SARS-CoV, MERS-CoV, and COVID-19 caused by SARS-CoV-2. Although the clinical manifestations of CoVs can range from mild cold-like symptoms to severe respiratory diseases, they share common features in their structure, modes of transmission, and natural reservoirs. Identifying natural reservoirs, as well as establishing intermediate hosts, is crucial for understanding the mechanisms of interspecies transmission of CoVs. These processes are often mediated by molecular interactions between viral spike (S) proteins and cellular receptors of different species, which contribute to zoonotic outbreaks. Thus, the interaction of various species and the study of these processes of viral spread, cross-species transmission, and pathogen evolution play a key role in ensuring global biological safety. Therefore, we conducted this review to summarize the data from existing studies focused on the taxonomy of CoVs, their main types, natural reservoirs, intermediate hosts, pathways of interspecies transmission, and the significance of the One Health concept as an interdisciplinary approach to monitoring, prevention and control of CoV infections at the intersection of human, animal, and environmental health. We examined databases such as PubMed, Science Direct, Web of Science, and Google Scholar to identify relevant scientific articles in English available for such a review. The aim of this work is to study the taxonomy and classification of coronaviruses, as well as to identify their natural reservoirs, intermediate hosts, and applicable control measures. A review of human and animal coronaviruses has revealed their evolutionary diversity, their main natural reservoirs, their intermediate hosts, and their interactions with cellular receptors. This information allows for a better understanding of the mechanisms by which the viruses are transmitted from animals to humans.

Three categories of microbial input appear to repeatedly trigger these "plasmablast storms": latent herpesvirus reactivations (Epstein-Barr virus, cytomegalovirus, human herpesvirus-6, varicella-zoster virus), acute respiratory or gastrointestinal infections including SARS-CoV-2, and chronic oral or gut dysbiosis. Although biologically distinct, these stimuli converge on innate sensing pathways driven by pathogen-associated molecular patterns such as unmethylated CpG DNA, single-stranded RNA, lipopolysaccharide, and bacterial lipoglycans. Through Toll-like receptors and type I interferon signalling, microbial signatures accelerate class switching, amplify inflammatory cytokine milieus, and lower B-cell activation thresholds, enabling rapid plasmablast mobilisation. Dysbiosis further maintains B cells in a hyper-responsive state by disrupting mucosal homeostasis and altering microbial metabolite profiles, thereby reducing the stimulus required to trigger plasmablast bursts. Once generated, these waves of oligoclonal plasmablasts home to inflamed tissues, where chemokine and adhesion landscapes shape their retention during flares. Emerging evidence suggests that such episodic plasmablast expansions promote autoantibody diversification, somatic hypermutation, and epitope spreading, progressively eroding tolerance. This review synthesizes these insights into a unified model in which infections and dysbiosis promote microbe-licensed plasmablast storms that influence the tempo and severity of autoimmune disease.}, }

This review summarizes the current knowledge on PEDV structural proteins, with an emphasis on membrane proteins as regulators of porcine innate immune responses. The molecular characteristics and intracellular localization of membrane proteins were described, and the reported effects on interferon signaling, inflammatory pathways, and cellular stress responses were examined. Findings from related coronaviruses were incorporated to highlight the conserved features and virus-specific differences in membrane protein-mediated host modulation. Available evidence suggests that membrane protein-associated interference with innate immune signaling may contribute to intestinal immune dysregulation and disease severity in neonatal piglets.

Methods: We conducted a narrative review supported by a structured literature search (PubMed/MEDLINE, Scopus, Web of Science; 1 January 2014-30 November 2025), with a narrative synthesis of observational studies, registry analyses, and meta-analyses addressing COVID-19-related changes in gastric cancer epidemiology, diagnosis, treatment, vaccination, and telemedicine. A PRISMA-style flow diagram was used to illustrate study selection. Results: Elective endoscopy volumes fell by up to 80%, leading to diagnostic backlogs and increased proportions of advanced-stage gastric cancer. Surgical postponements, modified chemotherapy and radiotherapy schedules, and reduced molecular/genetic testing further compromised outcomes. Conversely, vaccination, telemedicine, capsule endoscopy, and adaptive triage frameworks enabled partial recovery of services. Geographical variations were observed in the recovery of gastric cancer care services, with regions that had established screening infrastructure generally resuming activity more rapidly, whereas others experienced ongoing delays and diagnostic backlogs. Conclusions: This review integrates epidemiological, diagnostic, and therapeutic evidence to demonstrate how COVID-19 redefined gastric cancer care. By highlighting regional disparities and outlining a conceptual model for oncologic resilience, it provides an innovative framework for future crisis preparedness.

Methods: A narrative synthesis was undertaken after a systematic search of medical and engineering databases to 10 October 2025. Studies applying telemedicine, telehealth, telepresence or teleradiology to OMFS practice were eligible, including trials, observational cohorts, technical reports and surveys. Data were extracted in duplicate and organized thematically; heterogeneity precluded meta-analysis. Results: Fifty studies met the inclusion criteria. Telemedicine was mainly used for preoperative consultation and triage, postoperative follow-up, trauma teleradiology and tele-expertise, oncologic and oral medicine follow-up, temporomandibular disorders, and education or humanitarian work. In low-risk outpatient and postoperative settings, remote consultations showed high concordance with in-person plans, similar complication or reattendance rates, reduced travel, and high satisfaction. In trauma networks, telemedicine supported timely triage and reduced unnecessary inter-hospital transfers. Evidence in oral oncology and complex mucosal disease was more cautious, favouring hybrid models and escalation to face-to-face assessment. Data on cost-effectiveness and impacts on equity were limited. Conclusions: Telemedicine in OMFS has moved from niche innovation to a pragmatic adjunct across the clinical pathway.

In SARS-CoV-2, the correlation between inflammatory cytokines, such as IL-1, IL-6, and MCP-1, found in cerebrospinal fluid and brain tissues, indicates significant neurovascular inflammation. Astrogliosis and microglial nodules were observed, further emphasizing the inflammatory response triggered by the viral infections, again in parallel to those found in the brains of PWH. Epidemiologic data indicate that although SARS-CoV-2 infection rates in PWH mirror those in People without HIV (PWoH) populations, Long-COVID prevalence is markedly higher among PWH. Evidence of overlapping cognitive impairment, mental health burden, and persistent neuroinflammation highlights diagnostic complexity and therapeutic gaps. Despite plausible mechanistic synergy, direct neuropathological confirmation remains scarce, warranting longitudinal, biomarker-driven studies. Understanding these interactions is critical for developing targeted interventions to mitigate CNS injury and improve outcomes.}, }

This situation highlights the pressing demand for antiviral drugs employing novel mechanisms of action. Pentacyclic triterpenoids (PTs), a structurally varied group of compounds derived from plants, exhibit both antiviral and anti-inflammatory activities, making them attractive candidates for further therapeutic development. These natural products, along with their saponin derivatives, show broad-spectrum inhibitory effects against multiple SARS-CoV-2 variants (from Alpha to Omicron) via interactions with multiple targets, such as the spike protein, main protease (Mpro), RNA-dependent RNA polymerase (RdRp), and inflammatory signaling pathways. This review consolidates recent findings on PTs and their saponins, emphasizing their influence on the key structural features required for inhibiting viral attachment, membrane fusion, reverse transcription, and protease function. We systematically summarized the structure-activity relationships and their antiviral results of PTs based on different target proteins in existing studies. Furthermore, this work points toward new strategies for designing multi-target PT-based inhibitors with improved efficacy against Omicron and future variants.}, }

This review article discusses the eminence of nanobiosensors, as state-of-the-art tools, to investigate and clarify the connection between SARS-CoV-2 pathogenesis and gut microbiome imbalance. Nanobiosensors are uniquely advantageous owing to their sensitivity, selectivity, specificity, and reliable monitoring capabilities, making them well-suited for identifying both viral particles and microbial markers in biological samples. We explored a range of nanobiosensor platforms and their potential use for concurrently monitoring the gut dysbiosis induced by different pathological conditions. Additionally, we explore how advanced sensing technologies can shed light on the mechanisms driving virus-induced dysbiosis, and the implications for disease progression and patient outcomes. The integration of nanobiosensors with microfluidic devices and artificial intelligence algorithms has also been explored, highlighting the potential of developing point-of-care diagnostic tools that provide comprehensive insights into both viral infection and gut health. Utilizing nanotechnology, scientists and healthcare professionals may gain a more profound insight into the complex interaction dynamics between SARS-CoV-2 infection and the gut microenvironment.

This heightened vulnerability stems from multifactorial immune impairment, including defects in innate and adaptive immunity, chronic inflammation related to abnormal hemodynamics and hypoxia, reduced thymic function, and genetic syndromes affecting both cardiac and immune development. Viral pathogens-particularly respiratory syncytial virus (RSV), influenza viruses, and SARS-CoV-2-account for most infections, although bacterial pathogens remain relevant, especially in postoperative settings. Methods: This narrative review summarizes current evidence on infection susceptibility in children with CHD, the epidemiology and clinical relevance of major respiratory pathogens, and the effectiveness of available preventive measures. Literature evaluating immunological mechanisms, infection burden, vaccine effectiveness, and passive immunization strategies was examined, along with existing national and international immunization guidelines. Results: Children with CHD consistently exhibit higher rates of hospitalization, intensive care unit admission, mechanical ventilation, and mortality following respiratory infections. RSV, influenza, and SARS-CoV-2 infections are particularly severe in this population, while bacterial infections, though less common, contribute substantially to postoperative morbidity. Preventive options-including routine childhood vaccines, pneumococcal and Haemophilus influenzae type b vaccines, influenza vaccines, COVID-19 mRNA vaccines, and RSV monoclonal antibodies-demonstrate strong protective effects. New long-acting RSV monoclonal antibodies and maternal vaccination markedly enhance prevention in early infancy. However, vaccine coverage remains insufficient due to parental hesitancy, provider uncertainty, delayed immunization, and limited CHD-specific evidence. Conclusions: Respiratory infections pose a significant and preventable health burden in children with CHD. Enhancing the use of both active and passive immunization is essential to reduce morbidity and mortality. Strengthening evidence-based guidelines, improving coordination between specialists and primary care providers, integrating immunization checks into routine CHD management, and providing clear, condition-specific counseling to families can substantially improve vaccine uptake and clinical outcomes in this vulnerable population.}, }

Heterogeneous seroconversion rates and conflicting safety reports complicate the formulation of clear clinical guidelines. This systematic review and meta-analysis aim to aggregate existing evidence to determine the precise seroconversion and safety profiles of COVID-19 vaccines and identify key factors influencing immune response in SOTRs.<br><br>METHODS: A comprehensive literature search was conducted identifying 125 studies evaluating WHO/FDA-authorized vaccines in SOTRs. Outcomes were the pooled seroconversion proportion and safety profile. Subgroup analyses were performed based on vaccine type, transplanted organ, number of doses, and prior SARS-CoV-2 infection status, confirmed by leave-one-out sensitivity analysis and bootstrap methods.<br><br>RESULTS: Most studies assessed mRNA-based vaccines (123/125, 98.4%). The overall pooled seroconversion proportion across all SOTRs was significantly blunted at 0.49 (95% CI, 0.43 to 0.55), demonstrating high heterogeneity (I[2] = 94.2%). Seroconversion showed a clear positive dose-response relationship, increasing from 27% after one dose to 84% after four doses. Prior COVID-19 infection was the strongest predictor of a response, resulting in a pooled seroconversion of 0.90 (95% CI, 0.82 to 0.94; I[2] = 0%). Organ-specific analyses revealed the highest response in Liver recipients (0.80) and the lowest in Lung recipients (0.29). Vaccine platform analysis showed that the highest response was with mRNA-1273 (0.55) and the lowest with CoronaVac (0.29). The safety profile was limited.<br><br>CONCLUSIONS: SOTRs exhibit profound hypo responsiveness to COVID-19 vaccines; however, the extreme heterogeneity observed across studies necessitates a cautious interpretation of pooled seroconversion estimates. While the data indicates a significant dose-response relationship favoring an aggressive, multi-dose strategy, the apparent safety profile may reflect under-reporting and limited follow-up rather than confirmed safety equivalence. Rare but clinically critical outcomes, such as acute allograft rejection, remain inadequately characterized in the current literature. Consequently, while the prioritization of multi-dose regimens and hybrid immunity is supported to maximize protection, clinicians must recognize that individual responses remain highly variable, and the long-term immunological impact of repeated stimulation requires further standardized investigation.}, }

Among adults with solid tumors and hematological malignancies, infections are a major contributor to morbidity and mortality, with respiratory infections playing a particularly significant role. These infections not only reduce life expectancy but can also delay cancer therapy, negatively affect treatment outcomes, and increase healthcare costs. In recent years, the burden of respiratory infections in this population has been driven by influenza virus, SARS-CoV-2, respiratory syncytial virus, Streptococcus pneumoniae, and Bordetella pertussis. Effective vaccines are available for all these pathogens and are recommended for adults with cancer, yet vaccination uptake remains suboptimal despite their heightened vulnerability. This review provides practical guidance for healthcare professionals on vaccinating adults with cancer against respiratory infections, summarizing key information to help clinicians address vaccination-related complacency, confidence, and convenience. Evidence from studies in both the general population and cancer patients consistently shows that vaccination benefits outweigh potential risks, with adverse event rates comparable to those seen in individuals without cancer. Early vaccination is encouraged, as there is limited justification for delaying immunization even when immune responses may be reduced. Vaccine dosing aligns with recommendations for the general population, with important exceptions. Live attenuated vaccines should be avoided because of the risk of replication and disease in immunocompromised patients, and selected groups may require booster doses to achieve adequate protection. Notably, cancer immunotherapy does not appear to impair vaccine-induced immune responses.}, }

Motor symptoms improved (SMD -0.46, 95% CI -0.69 to 0.24; P=.001), and ADL showed substantial impairment reduction (SMD -0.79, 95% CI -1.04 to -0.54; P=.002).

It preferentially infects the respiratory epithelium and affects infants, the elderly, and immunocompromised populations. The clinical manifestations of the HMPV range from mild upper respiratory symptoms to severe diffuse bronchopneumonia. As of late 2024 and early 2025, HMPV has been responsible for 6.2% of positive respiratory illness tests and 5.4% of respiratory-associated hospitalizations in China, surpassing COVID-19, rhinovirus, and adenovirus. HMPV is a non-segmented, negative-sense single-stranded RNA virus with a genome of about 13.3 kb, and it is genetically related to Orthopneumovirus, particularly respiratory syncytial virus (RSV). Its transmission occurs primarily within households, and the virus poses significant risks to vulnerable populations. Immunologic responses to HMPV infections are diverse, with limited lasting immunity, leading to frequent reinfections. Diagnosis is problematic due to overlapping clinical manifestations of the disease alongside other respiratory viruses like RSV and influenza. Presently, no vaccines or antiviral treatments are available for HMPV, though several vaccine candidates are under investigation, including mRNA-1653 and IVX-A12, which have shown promising results in Phase I and Phase II clinical trials. Recent advances in understanding HMPV's molecular biology and immune modulation have led to exploring new therapeutic strategies, including monoclonal antibodies, fusion inhibitors, and RNA interference-based therapies.}, }

A remarkable recent discovery is that human autoantibodies (autoAbs) neutralizing the activities of IFN-Is phenocopy inborn errors of immunity and markedly exacerbate susceptibility to life-threatening infections. Development of these pathogenic autoAbs in humans is strongly linked to genetic and nongenetic factors affecting thymic function, and they are estimated to be present in >100 million people worldwide with a prevalence that increases with age. Here, we review major advances from the last few years that have improved our mechanistic understanding of human IFN-I autoAb development and function, as well as their association with a significant proportion of different severe viral diseases. In particular, we highlight how neutralizing IFN-I autoAbs can persist in individuals for decades, compromising IFN-I-mediated defenses, and underlying subsequent critical infections with diverse pathogens, including SARS-CoV-2, West Nile virus, tick-borne encephalitis virus, seasonal influenza viruses, herpesviruses, and rare zoonoses caused by MERS-CoV, flaviviruses, and avian H5N1 influenza A virus. Furthermore, we discuss how neutralizing IFN-I autoAbs facilitate severe adverse events with live-attenuated viral vaccines, such as the yellow fever or chikungunya virus vaccines, and suggest how implementation of IFN-I autoAb diagnostics in at-risk populations may be clinically beneficial with current prophylactic or therapeutic options. Finally, in the context of new experimental insights into how autoAbs block the ability of IFN-Is to engage with the IFNAR1/IFNAR2 receptors, we detail future opportunities to design advanced novel therapeutic strategies that might specifically mitigate IFN-I autoAb pathogenic effects.}, }

This scoping review evaluated current evidence on the use of CCM in assessing corneal nerve fibre changes across neurodegenerative diseases (NDDs) and explored its potential as a paraclinical diagnostic and monitoring tool. A comprehensive search of PubMed and Scopus was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews guidelines to identify studies reporting quantitative CCM metrics, including corneal nerve fibre density (CNFD), corneal nerve branch density (CNBD) and corneal nerve fibre length (CNFL). Both cross-sectional and longitudinal studies of patients with NDDs were included, and findings were narratively synthesised. 50 studies were included: Parkinson's disease (n=13), multiple sclerosis (n=11), cerebrovascular accidents (n=7), post-COVID-19 neuropathy (n=5), amyotrophic lateral sclerosis (n=4), chronic inflammatory demyelinating polyneuropathy (n=4), Alzheimer's disease (n=3), Fabry disease (n=2) and neurofibromatosis type 1 (n=1). CNFL and CNFD were consistently reduced in Parkinson's disease, multiple sclerosis, cerebrovascular accidents, amyotrophic lateral sclerosis, chronic inflammatory demyelinating polyneuropathy and post-COVID-19 neuropathy, whereas CNBD results were inconsistent. The strongest evidence supported the role of CCM in Parkinson's disease and multiple sclerosis. CNFL and CNFD emerged as the most reliable CCM-derived metrics across NDDs, supporting their potential as objective biomarkers for neurodegeneration. While findings support the potential of CCM as a paraclinical diagnostic tool, methodological heterogeneity in image acquisition, analysis software and study design limited comparability.

Two key concepts for understanding emotional responses during this period include Sense of Control (SoC) and Locus of Control (LoC). The SoC refers to the general perception of personal agency, while the LoC is a more specific framework that classifies control perceptions as either internal (believing one has control over life events) or external (attributing outcomes to external forces). Previous studies indicate that a more external LoC and a low SoC are associated with greater psychological vulnerability in stressful contexts, such as during the pandemic, which can amplify symptoms of anxiety and depression. This integrative review aims to gather and synthesize studies that explore the relationship between LoC and/or SoC and symptoms of anxiety and depression during the COVID-19 pandemic.<br><br>MAIN TEXT: A systematic search was conducted in PubMed, Scopus, and BVS databases, focusing on studies published within the last 5&#xa0;years. Quantitative studies with adult samples were considered eligible while excluding those with specific pre-existing conditions. After removing duplicates, titles and abstracts were screened, resulting in 12 full-text studies to be reviewed. Of these, nine met inclusion and exclusion criteria and were included in the analysis. An emerging pattern showed that individuals with external LoC and low SoC had higher levels of anxiety and depression during the COVID-19 pandemic. The role of LoC and SoC as moderators of psychological distress was documented, reinforcing prior evidence that individuals with an external LoC are more vulnerable to mental health challenges in times of crisis. Furthermore, these constructs influenced behavioral responses to the pandemic, with higher SoC and internal LoC associated with more proactive and responsible coping strategies.<br><br>CONCLUSION: Both LoC and SoC play critical roles in understanding the psychological impacts of the pandemic. Despite populational and methodological diversity, most studies point to a clear correlation between perception of control and levels of anxiety and depression, highlighting the importance of interventions that increase the perception of personal control to reduce psychological distress.}, }

Despite differences in viral biology and transmission, mounting evidence reveals a convergent theme of maternal immune activation during pregnancy. Even without vertical transmission, virus-elicted maternal immune responses alter the maternal-fetal interface and gut microbiome, reshaping fetal immunity and birth outcomes. These immune perturbations increase susceptibility to infections, neurodevelopmental disorders, and immune-mediated diseases later in life. Here, we discuss viral immune evasion strategies that modulate maternal immunity and review current clinical and emerging therapeutic approaches aimed at mitigating long-term consequences in exposed children. Understanding how prenatal viral exposure shapes lifelong health is critical for developing targeted interventions and reducing postnatal disease burden.}, }

Research on the reverse genetics of coronaviruses has always been a hot spot. Coronavirus cannot only infect mammals, but also infect humans, showing its wide host adaptability. The mutation ability of the coronavirus is extremely strong. Recently, the rapid mutation rate of SARS-CoV-2 has made the development of vaccines and therapeutic methods face great challenges. At present, reverse genetics technology is a molecular biology tool. This process primarily involves cloning the full-length genome cDNA of the virus onto a vector, and then reproducing the modified progeny virus in the cell to achieve accurate modification of the virus's genetic characteristics. This technology can explore the external characteristics of mutants and the evolution of their traits through artificial operations, such as knockout and site-directed mutagenesis of specific genes, and then reveal the biological functions of genes. This article will review the research progress of the coronavirus reverse genetic operating system. In the past research, reverse genetics technology has made remarkable progress in the field of coronavirus research. Researchers have successfully constructed various reverse genetic systems for coronaviruses, including IBV, SARS-CoV-2, and MERS-CoV.

Initially identified as a syndecan-binding molecule, syntenin has since emerged as a central hub connecting membrane receptors to intracellular signaling pathways that regulate adhesion, motility, immune signaling, and cellular plasticity. While extensively studied in cancer and neural development, recent discoveries reveal that a wide range of viruses exploit syntenin to facilitate their replication, assembly, or dissemination. This review consolidates current evidence across diverse viral infections to elucidate the molecular mechanisms underlying the interaction between syntenin and viruses. Coronaviruses utilize syntenin to link PDZ-binding motifs to p38 MAPK-driven inflammation and endosomal entry. Papillomaviruses and Epstein-Barr virus hijack the CD63-syntenin-ALIX complex to control vesicle-mediated trafficking. Hepatitis C virus employs it to secrete E2-coated, antibody-resistant exosomes. Dengue virus harnesses its mosquito homolog AeSyntenin to package sfRNA for transmission. Human T-cell leukemia virus type 1 employs its Tax-1 oncoprotein to bind the PDZ domains of syntenin, remodel extracellular vesicle cargo, and promote viral spread. In contrast, during human immunodeficiency virus infection, syntenin restricts viral fusion at the plasma membrane, though the nucleocapsid mimics its PDZ tandem to promote virion release. Collectively, these findings establish syntenin as a dynamic regulator at the host-virus interface, capable of exerting both proviral and antiviral effects. Emerging pharmacological strategies targeting syntenin PDZ domains further underscore its potential as a broad-spectrum, host-directed antiviral target.}, }

Telerehabilitation—defined as the delivery of rehabilitation services via electronic information and communication technologies (e.g., video conferencing and phone calls for improved access; mobile apps, websites, and virtual reality (VR) for enhanced engagement and self-management)—offers a potentially promising alternative to overcome these obstacles (Buckingham et al., JMIRx Med 3:e30516, 2022). This narrative review synthesizes evidence from studies conducted between January 2000 and November 6, 2025 on telerehabilitation’s role in UI management in women, focusing on stress UI, PFMT efficacy, and comparative outcomes with in-person therapy. It addresses gaps in prior systematic reviews by focusing on patient-centered designs and cultural adaptations. Key findings from 25 included studies indicate that telerehabilitation is feasible, effective in reducing UI symptoms, improving quality of life (QoL), and enhancing adherence, particularly through mobile apps and group-based interventions (Asklund et al., Neurourol Urodyn 36:1369-76, 2017; Sjostrom et al., BJU Int 112:362-72, 2013; Hoffman et al., Gynecol Scand 96:1180-7, 2017). However, limitations include heterogeneity in interventions, small sample sizes in many studies, lack of long-term data, absence of male participants, limited validation in rural or cognitively impaired populations, and insufficient cultural adaptations for diverse groups. Recommendations include developing tailored telerehabilitation programs incorporating biofeedback and interdisciplinary approaches to address UI holistically. This review highlights telerehabilitation’s potential as a scalable, cost-effective intervention, particularly post-COVID-19, and calls for further research in diverse female populations.}, }

In Ukraine, the estimated burden is approximately 75,000 patients, although national data remain limited. Since 2016, the Amosov National Institute of Cardiovascular Surgery in Kyiv has been a leading center for HOCM surgery, primarily performing septal myectomy (SM) with concomitant mitral valve (MV) repair. This review summarizes the evolution of the Institute's surgical program, outcomes, and challenges faced under extraordinary circumstances.<br><br>METHODS: Institutional experience with SM and MV repair between 2016 and 2025 was reviewed. Preoperative evaluation included transthoracic echocardiography (TTE), cardiac magnetic resonance (CMR) imaging, and/or computed tomography (CT). A refined transaortic SM technique was applied to optimize septal resection, relieve left ventricular outflow tract (LVOT) obstruction, and address dynamic mitral regurgitation (MR).<br><br>RESULTS: SM consistently reduced LVOT gradients and eliminated MR in the majority of patients. In-hospital mortality remained below 1%, with a low incidence of major complications directly attributable to myectomy.

Male infertility represents both a biomedical challenge and a societal concern. Our review considers COVID-19's biophysical mechanisms affecting the male reproductive system and focuses on the prognostic implication. Current evidence highlights two primary pathways of SARS-CoV-2 impact: hyperthermia and oxidative stress. The first pathway, as reported, significantly increases sperm aneuploidy and, as a result, has adverse effects on spermatogenesis and causes sperm DNA breaks. The second pathway of coronavirus impact on infertility is oxidative stress. During it, the level of formation of reactive oxygen species (ROS) increases and damages sperm membrane by lipid peroxidation. These mechanisms are interrelated, as fever-induced oxidative stress may alter redox-active metal homeostasis, further exacerbating cellular damage. Understanding these pathogenic processes enables targeted therapeutic development and preventive strategies for COVID-19-related male reproductive dysfunction.}, }

In China, the National Health Commission of China announced that patients with COVID-19 who were treated with traditional Chinese medicines (TCMs) combined with antiviral drugs effectively alleviated their symptoms and recovered. Among these TCMs, Xuebijing (XBJ) injection plays an important role in the treatment of patients with COVID-19.

In response, Egypt has pioneered contextually grounded adaptive approaches, such as task shifting, integrating mental health into primary care, and developing culturally-adapted psychosocial interventions led by trained non-specialists. The COVID-19 pandemic accelerated this trajectory of modernization. Telepsychiatry services, nationwide psychosocial support hotlines, AI-driven tools, and the establishment of Egypt's dedicated psychiatric COVID-19 hospital highlight the country's capacity for rapid, context-sensitive adaptation to innovate while remaining anchored in its cultural fabric. Together, these developments illustrate how mental health systems can evolve by embracing tradition as a resource rather than a barrier, and by leveraging technology to expand equity, accessibility, and cultural relevance. This review positions Egypt as a powerful case study of how cultural heritage and adaptive, problem-driven strategies can be innovatively harmonized to shape the future of mental health care in the region, where originality lies in contextual responses rather than technological novelty.}, }

This study compares the incidence of seizures before and during the Omicron variant period to determine if certain variants increase risk. Using PRISMA-P protocol, four databases (PubMed, Embase, Scopus, Web of Science) were searched. Cohort studies reporting febrile seizures in children (up to 18 years of age) with confirmed SARS-CoV-2 infection were included. We provide descriptive summaries of the incidence of febrile seizures across hospital, emergency, and community settings, as well as a meta-analysis between Omicron-predominant and pre-Omicron periods. We included 36 studies comprising 82,591 children with SARS-CoV-2 infection, of whom 2051 experienced febrile seizures. In 29 studies of hospitalized children with SARS-CoV-2, the incidence of febrile seizures varied widely, with a median of 7 per 100 (range 1.06-25.54) children. High heterogeneity was observed, and studies from emergency and community settings were underpowered. Seven studies found that unvaccinated children hospitalized with SARS-CoV-2 had more febrile seizures during the Omicron-predominant (median 11.8 per 100) than during the pre-Omicron period (median 0.7 per 100). The pooled incidence was 11.27 per 100 cases for the Omicron-predominant and 0.66 per 100 for the pre-Omicron period (p < 0.0001).<br><br>CONCLUSION: There was a trend toward more reported febrile seizures among hospitalized children with SARS-CoV-2 during the Omicron-predominant than the pre-Omicron period.

Advances in connectivity, artificial intelligence (AI), and wearable devices are facilitating the early detection of clinical deterioration, personalized interventions, and improved self-management, thereby optimizing the use of healthcare resources. Strong evidence supports the benefits of telemonitoring in COPD, particularly in reducing exacerbations and hospital admissions, whereas results are more heterogeneous in asthma and emerging conditions such as interstitial lung diseases. Telemonitoring systems leverage AI-driven analytical frameworks and interoperable digital platforms to process and interpret large volumes of patient data, enabling both automated responses and targeted human interventions. Key challenges include ensuring patient engagement, addressing digital literacy and inequities in access, safeguarding data privacy, and integrating digital solutions into standard care and reimbursement frameworks. The COVID-19 pandemic accelerated the adoption of telemonitoring, confirming its feasibility and acceptability, but also revealed persistent gaps in long-term cost-effectiveness and implementation strategies. Future directions should focus on integrating telemonitoring with AI-supported, coordinated clinical decision-making, enhancing system interoperability, and above all, prioritizing equitable access to digital care. Telemonitoring is poised to become a central component of respiratory patient management, although its large-scale implementation will require overcoming existing technical, ethical, and organizational barriers to fully realize its clinical potential.}, }

While observational studies suggest a benefit from antifungal prophylaxis, its efficacy remains unconfirmed by randomized trials, and its impact on clinical outcomes is unclear.<br><br>METHODS: We conducted a systematic review and meta-analysis (PROSPERO: CRD42023462988) of nine ICU-based studies, comparing antifungal prophylaxis (primarily inhaled amphotericin B or systemic posaconazole) with standard care. The primary outcome was CAPA incidence; secondary outcomes included mortality, time to CAPA onset, and ICU length of stay. Risk of bias was assessed using ROBINS-I, with publication bias evaluated via Egger&#x2019;s test and funnel plot symmetry. Subgroup and sensitivity analyses were performed to assess heterogeneity and robustness.<br><br>RESULTS: Among 1,321 patients included, antifungal prophylaxis significantly reduced CAPA incidence (RR 0.21, 95% CI 0.14&#x2013;0.33; p&#x2009;<&#x2009;0.001) and CAPA risk (OR 0.22, 95% CI 0.12&#x2013;0.40; p&#x2009;<&#x2009;0.001). Inhaled amphotericin B demonstrated consistent benefit (RR 0.18, 95% CI 0.06&#x2013;0.52; p&#x2009;=&#x2009;0.001), whereas systemic posaconazole showed variable results. No significant effects were observed on mortality (RR 1.05; p&#x2009;=&#x2009;0.69), time to CAPA onset (MD &#x2212;0.33&#x2009;days; p&#x2009;=&#x2009;0.73), or ICU stay duration (MD 1.59&#x2009;days; p&#x2009;=&#x2009;0.34).

The favorable profile of topical amphotericin B necessitates direct comparison with systemic azoles in future trials. Prospective, randomized studies are imperative to validate these findings for universal application, refine prophylactic regimens for broader populations, and assess long-term clinical and economic impacts.<br><br>SUPPLEMENTARY INFORMATION: The online version contains supplementary material available at 10.1186/s12879-026-12694-z.}, }

Following this onset, their needs for mental health services have only increased. Yet, researchers encounter barriers to confronting these crises. The effects of therapies tested in controlled trials in the present day appear to be no more potent than those of their predecessors tested in trials conducted decades ago. Across these decades of scholarly work, researchers have invested far more of their efforts toward improving technologies for therapies than they have toward improving technologies for the assessment tools used to estimate therapeutic effects. The tools used today look a lot like those used in the 1970s-mainly surveys and interviews-and our strategies for integrating the data these tools produce focus on the sliver of their data that converge or yield the same results about youth mental health. Decades of work reveal that these integration strategies are incompatible with the data conditions that typify youth mental health assessments. We must invest in innovative assessment tools and integration strategies that capitalize on all the valid data produced by these conditions. This paper details pioneering directions in future research about psychological assessment. We describe the conceptual foundations underlying these research directions and highlight recent work by the authors and others supporting this pursuit. If we empower the assessment researchers of today to develop technologically innovative assessment tools and integration strategies, then we equip the therapy researchers of tomorrow to demonstrate that investing in therapy technologies pays off.}, }

However there is increasing awareness of defects in other cellular processes, that can predispose to severe infectious disease. Recently, defects in autophagy-related genes or -processes have been demonstrated to predispose to life-threatening viral diseases, including defects in autophagy-related genes in patients with herpes simplex virus and varicella zoster virus infections in the central nervous system, as well as impairment of noncanonical antiviral immunity in critical COVID-19. However, the molecular mechanisms and complex intersections between autophagy, metabolism, cell death, and inflammation, and how defects in autophagy-related proteins may interfere with these cellular processes, are only now starting to emerge. This review presents the current knowledge on inborn errors of autophagy discovered in patients with severe viral infection and discusses some of the remaining knowledge gaps in our understanding of how autophagy processes act against viruses, how immunopathology and lack of viral control ensues when they fail, and how these insights may be translated into clinical medicine.}, }

Further research is required to evaluate the diagnostic accuracy, cost-effectiveness, and performance of POC tools in forensic settings. Comprehensive guidelines and standardized operating procedures should be developed to ensure the successful implementation of POC diagnostics in forensic investigations.

Some patients progress to pure red cell aplasia (PRCA) and/or megakaryocytic aplasia, often following prior chemotherapy or radiotherapy. Similar to Good syndrome and PRCA, thymectomy fails to alleviate AA, and spontaneous improvement is rare. Treatment options for thymoma-related aplastic anemia include cyclosporine A (CsA) monotherapy, CsA combined with glucocorticoids, thrombopoietin receptor agonists (TPO-RAs), and allo-HSCT.

Recent epidemiological studies have indicated a markedly increased incidence of myocarditis following SARS-CoV-2 infection and mRNA COVID-19 vaccinations (to a lesser extent) compared to pre-pandemic statistics. While a significant number of cases follow a mild and self-limiting disease course, severe manifestations can lead to arrhythmias, heart failure, or even sudden cardiac death. Importantly, accumulating evidence indicates that even mild myocarditis confers an elevated long-term risk of adverse cardiovascular outcomes. Beyond clinical and imaging-based observations, recent advances highlight a critical role for host genetic susceptibility in modulating immune responses, myocardial injury, and disease severity. This review provides a comprehensive synthesis of the etiology, pathophysiological mechanisms, clinical spectrum, diagnostic approaches, and evidence-based management of COVID-19-associated myocarditis, while critically integrating emerging genetic and transcriptomic insights that may explain disease heterogeneity, variable inter-individual susceptibility, and long-term prognosis.

These resources can also help safety management practices today as the pandemic begins to wind down.<br><br>CONCLUSIONS: Future research should focus on identifying ways to strengthen employees' social and psychological resources without relying on disasters. To this end, an integration of conservation of resource theory and behavioral theory may be useful.}, }

This review defines programmable LNPs as systems whose composition and interfacial chemistry are tuned to control organ tropism, cell specificity, intracellular trafficking, and immune interactions. We summarize design rules across four core components (ionizable lipid, phospholipid, cholesterol, PEG-lipid) and highlight levers like apparent pKa optimization (∼6-7 for hepatic delivery), biodegradable linkers, PEG-anchor-dependent shedding, ligands (e.g., GalNAc), and selective organ-targeting (SORT) lipids that redirect biodistribution beyond the liver. We survey advances in data-guided formulation, including DNA-barcoded in vivo libraries, machine learning, and physics-based prediction, plus scalable manufacturing (microfluidics, confined impinging-jet mixing, tangential-flow filtration) and Quality-by-Design with process-analytical technologies. A comprehensive characterization toolkit (size/ζ-potential, cryo-EM/SAXS, RNA encapsulation and integrity, apparent pKa, in vivo barcoding) maps to critical quality attributes. Applications span vaccines, protein replacement, siRNA/ASO delivery, and CRISPR platforms, with clinical examples like patisiran, COVID-19 and RSV mRNA vaccines, in-human transthyretin (TTR) editing, and individualized melanoma vaccination. We analyze translational constraints like endosomal escape, reactogenicity and anti-PEG immunity, complement activation, and lot-to-lot control, plus success factors: corona-aware design, dose-efficient potency at low lipid burden, redosing strategies, and fit-for-purpose biomarkers. Together, programmable LNPs offer a generalizable path to extrahepatic, cell-aware RNA medicine when coupled to rigorous analytics and platform manufacturing.}, }

In South Africa, the first case was confirmed in early March 2020. According to the WHO, disruptions in essential services due to the COVID-19 pandemic occurred worldwide. The COVID-19 pandemic affected access to maternal and child health (MCH) services in many countries, including South Africa. The study aimed to map and describe the existing evidence on the impact of the COVID-19 pandemic on the access to and delivery of maternal, neonatal, and child health (MNCH) services in South Africa.<br><br>METHODOLOGY: This was a scoping review of studies published between 2020 and 2023. We searched databases such as PubMed, MEDLINE, EBSCOhost, and Google Scholar. Data were exported to the Rayyan software, where screening, checking of duplicates, and selection of final studies for review were performed. The information from the identified studies was exported to ATLAS.ti 23.1 software for analysis. Content analysis was performed, and data were presented in predetermined themes using the MCH cascade.<br><br>RESULTS: The results from 25 articles showed a mixed view, whereby some studies showed a decrease at the beginning of the pandemic in April 2020, in the uptake of family planning, antenatal care, labor and delivery, postnatal care, under-five immunizations, and cervical cancer screening services. However, other studies found increased uptake of family planning, antenatal care, labor and delivery, and under-five immunization services. Some studies showed resilience in the overall first antenatal visits, adolescents' visits to family planning, and postnatal care, as they remained constant.<br><br>CONCLUSION: The findings show both positive and negative impacts of the COVID-19 pandemic on MNCH services in South Africa. While the pandemic significantly disrupted access to essential services, some areas demonstrated resilience, with increased visits for antenatal care, adolescent family planning, and postnatal services. These insights are critical for guiding decision-makers, health managers, and frontline healthcare workers in preparing for future public health emergencies. Ensuring continuity of MNCH services during crises must be a priority. Strengthening the health system and building resilience are essential to safeguard MCH, even in the face of disruptions.}, }

A systematic search was conducted in MEDLINE, EMBASE, and Web of Science for peer-reviewed literature published up to 31 July 2024. Studies were included if they reported public health actions in response to WES related to infectious diseases in human populations. Two reviewers independently screened studies and extracted data on public health responses, sampling, and analytical methods.<br><br>RESULTS: Of the 6,630 articles screened, 49 met the inclusion criteria. Most studies (92%) were published between 2021 and 2024, with SARS-CoV-2 as the primary focus (82%), followed by poliovirus (16%). Research was largely conducted in high-income regions: North America (51%), Asia (22%), and Europe (14%). Target populations included urban residents (57%) and on-campus students (31%) and local authorities were more often involved in WES efforts than national agencies (51% vs. 33%). In 75% of studies, at least two public health actions were implemented, and 20% reported five or more. The most common actions related to reactive disease control (n = 69), including testing, isolation, and contact tracing. Proactive disease control actions (n = 33) and public health communication (n = 22) were also described. Weekly sampling (57%) and composite methods (67%) were most used. Manhole sampling, despite equal frequency with treatment plant sampling (35%), led to significantly more public health actions (61 vs. 35). Long-term surveillance was often reported but rarely sustained. Quantitative and molecular analyses dominated; sequencing was rarely used (4%).<br><br>CONCLUSION: While reporting on public health actions following WES remains limited, this review illustrates its potential to inform timely, local interventions. Future studies should broaden pathogen targets, embed public health action planning in study design, and expand WES use in low-resource settings.}, }

IPD-MAs enable researchers to more effectively separate spurious heterogeneity related to differences in measurement from clinically relevant heterogeneity from differences in underlying risk or distribution of factors that modify disease progression. This tutorial describes the steps needed to conduct an IPD-MA of an emerging pathogen and how IPD-MAs of emerging pathogens differ from those of well-studied exposures and outcomes. We discuss key statistical issues, including participant- and study-level missingness and complex measurement error, and present recommendations. We review how IPD-MAs conducted during the COVID-19 response addressed these statistical challenges when harmonizing and analyzing participant-level data related to an emerging pathogen.

As a leading member of the ESKAPE group, A. baumannii has accumulated extensive resistance to multiple antibiotic classes, including carbapenems, resulting in the widespread emergence of multidrug-resistant (MDR), extensively drug-resistant (XDR), and pan-drug-resistant (PDR) strains. This review provides a chronological overview of the evolution of antimicrobial therapies used against A. baumannii, spanning the early era of penicillins and tetracyclines to contemporary agents such as eravacycline and ceftazidime-avibactam. We delineate the molecular mechanisms underlying resistance development, including carbapenemase production, robust RND efflux systems, horizontal gene transfer, biofilm formation, and the global dissemination of high-risk international clones (IC1-IC9). The compounding impact of the COVID-19 pandemic on the spread of carbapenem-resistant A. baumannii (CRAB) is also examined. A special emphasis is placed on Zosurabalpin, a first-in-class macrocyclic peptide antibiotic with a unique mechanism of action that targets the LptB2FG complex essential for lipooligosaccharide (LOS) transport and outer membrane assembly. Preclinical data and emerging clinical findings highlight its potent activity against highly resistant CRAB strains and its ability to circumvent conventional resistance pathways, marking it as a promising candidate in the antimicrobial pipeline. Finally, we evaluate the limitations of current treatment modalities and explore emerging strategies, including phage therapy, novel target discovery, and non-traditional therapeutics, offering a forward-looking perspective on restoring and sustaining effective anti-Acinetobacter interventions.}, }

Key limitations include poor test specificity, the absence of potent antivirals or therapeutic vaccines, lack of curative therapy, no demonstrated population-level benefit, and psychosocial harms associated with diagnosis. Current practice instead emphasizes diagnostic testing in symptomatic persons and targeted screening in defined contexts&#x2014;such as among people with HIV in specific clinical situations, sex partners of those with HSV-2 infection, certain pregnant women, persons seeking sexual health care, and persons with recurrent or atypical symptoms&#x2014;where results may directly inform management.

New evidence demonstrating that interventions can achieve measurable population-level reductions in disease burden or transmission, together with future advances in diagnostics and therapeutics, may eventually justify integrating routine HSV-2 screening into broader contexts, including into HIV prevention and care.}, }

Yet, while RNA-LNPs have reached clinical maturity, their DNA counterparts remain comparatively underexplored, despite holding great promise for gene replacement and genome-editing therapies. In this review, we turn the spotlight on DNA-loaded LNPs, examining how their structure, composition, and biological behavior differ from RNA-LNPs, their natural point of reference, and from earlier lipid-based systems such as cationic liposome/DNA complexes (lipoplexes). DNA-LNPs tend to form larger, more heterogeneous, and often multilamellar particles due to the intrinsic stiffness and high charge density of DNA. These distinctive features call for dedicated design strategies, including the use of cationic lipids, pre-condensation agents, and optimized PEGylation schemes. Moreover, DNA profoundly influences the biomolecular corona that forms in biological fluids, which in turn shapes immune recognition, circulation, and tissue targeting. By highlighting these unique physical and biological challenges, this review underscores the need to move beyond simply adapting RNA-based formulations. Instead, a cargo-informed design approach will be key to unlocking the full therapeutic potential of DNA-LNPs in next-generation gene delivery.}, }

The clinical phenomenology of motor tics ranges from mild twitches affecting a single facial muscle to orchestrated contractions of different muscular districts resembling purposeful behaviors. Likewise, the repertoire of vocal tics (also called phonic tics) covers the whole spectrum between isolated grunting noises and meaningful strings of words. Simple and complex tics arguably sit on a continuum of symptom severity and respond to the same treatment interventions. The diagnosis of Gilles de la Tourette syndrome (GTS) is based on the presence of multiple motor tics plus at least one vocal tic, with onset before the age of 18 years and chronic course. It has been argued that the different tic disorders belong to a spectrum of increasing complexity, from the transient form (provisional tic disorder), through persistent motor or vocal tic disorder, to GTS. However, the clinical phenotype of GTS stands out because of the frequent association with specific behavioral problems, ranging from tic-related obsessive-compulsive disorder to other neurodevelopmental conditions. The diagnosis of tic disorders is based on clinical observation and requires expertise. The recent outbreak of functional tics, documented across several countries during the COVID-19 pandemic, introduced unprecedented challenges to the differential diagnosis of neurodevelopmental tics.}, }

Until the early 2010s, functional tic disorders were rather uncommon in the differential diagnosis of tics, and only few cases describing their features had been published. However, over the past 10 years there has been a steady increase in the frequency of these cases that peaked throughout the COVID-19 pandemic. On the one hand, the rise in functional tic cases created new challenges of diagnosis and treatment. At the same time, it also pushed the field forward to delineate helpful clinical clues, as well as to work toward specific consensus diagnostic criteria for functional tics and tic-like behaviors. Here, we first provide a historical summary on the debate between neurodevelopmental and functional tics. We then track relevant literature on functional tics and tic-like cases and discuss their salient features, such as an acute onset with severe symptoms and complex repetitive behaviors that typically occur in late adolescence or early adulthood, a large variability of symptoms including spontaneous symptom remissions and re-emergence, and a high prevalence of phonations and vocalizations with the common use of swearwords or variable sentences. In addition, it is common to see an overlap with additional functional neurologic symptoms, such as functional tremor or nonepileptic seizures. In diagnostically challenging cases, neurophysiologic evaluation, including surface electromyography and electroencephalography, may be useful, and markers such as the premotor potential (Bereitschaftspotential) and event-related desynchronization/synchronization may hold promise. Effective management of functional tics begins with an accurate diagnosis and often requires a multidisciplinary approach. Cognitive-behavioral therapy and the Comprehensive Behavioral Intervention for Tics may be particularly useful, alongside addressing comorbid psychiatric conditions. Currently there is an absence of standardized treatment protocols; individualized care plans tailored to each patient's specific needs are generally the most effective approach.}, }

We aimed to characterize the risk of hospitalization and death in real-world US clinical practice for untreated patients at high-risk for progression to severe COVID-19 and critically assess differences in patient populations.<br><br>METHODS: We conducted a systematic literature review to identify US real-world evidence studies (December 21, 2021 &#x2013; January 30, 2024) of patients aged 12&#x2009;years and older diagnosed with mild-to-moderate COVID-19, at high risk for progression to severe COVID-19, and treated with nirmatrelvir/ritonavir (NMV/r) or untreated/best supportive care. Primary outcomes were reported risks of all-cause hospitalization, death, and hospitalization or death at 1&#x2009;month. To account for heterogeneity across studies and confounding within studies, outcomes were estimated as: 1) observed risk, untreated risk as reported, 2) within-study adjusted risk, applying an adjusted treatment effect within studies to calculate risk in the untreated population, and 3) adjusted and standardized estimate, using the relative risk reduction for all-cause hospitalization or death from the study with highest validity.<br><br>RESULTS: Of 1023 studies screened, we retained 23 for data extraction after applying inclusion and exclusion criteria (384,793 NMV/r patients from 22 studies; 1,062,757 no treatment from 14 studies). Studies were heterogenous, primarily retrospective, utilizing claims (e.g., TriNetX) and integrated health system data (e.g., Veterans Affairs). Most (n&#x2009;=&#x2009;21, 91%) were US only; 20 (87%) were cohorts from December 2021 onward.

However, durable clinical benefit is achieved in only a subset of patients, and resistance to ICIs remains a major clinical challenge. Mechanistically, resistance arises from multiple, often overlapping processes, including inadequate tumor antigen presentation, dysfunctional T-cell priming and expansion, and the presence of physical and immunosuppressive barriers within the tumor microenvironment that limit immune cell infiltration and effector function. Cancer vaccines have re-emerged as a rational immunotherapeutic strategy to overcome these obstacles by inducing de novo or amplifying pre-existing tumor-specific immune responses, thereby enhancing long-term immunological memory while maintaining a favorable safety profile. Advances in antigen discovery, neoantigen prediction, and vaccine platforms have accelerated the development of both personalized and off-the-shelf neoantigen vaccines. Although personalized neoantigen vaccines have gained considerable attention following the success of mRNA-based COVID-19 vaccines, off-the-shelf approaches offer advantages in scalability, cost, and manufacturing timelines, facilitating broader clinical implementation. Accumulating preclinical and clinical evidence suggests that cancer vaccines are more effective in the adjuvant setting than in the metastatic setting, where high tumor burden and an immunosuppressive tumor microenvironment constrain vaccine-induced immune responses. Consistent with their limited efficacy as monotherapy, contemporary clinical trials increasingly evaluate cancer vaccines in combination with ICIs or other immunotherapeutic agents to enhance T-cell activation, reverse immune suppression, and restore antitumor immunity. This review synthesizes current mechanistic insights, highlights ongoing clinical efforts, and discusses future directions for rational cancer vaccine development in lung cancer, with an emphasis on overcoming resistance to ICI.}, }

Classical approaches (such as inactivated, live attenuated, and recombinant) can be shown to have reduced the burden of infectious diseases; however, they are also limited by their inability to scale production and prolonged development, as well as cold-chain limitations. The lacks became apparent through the pandemic and drove the demand for more agile, adaptive technology that COVID-19 has highlighted. The current review questions the goal of streamlining the immunization approaches in the face of emerging pathogens through a structured narrative comparison of immunogenicity, safety, efficacy, and platform stability of modern vaccination platforms within a narrative review framework. This analysis is anchored by a narrative synthesis of immunological, regulatory, and clinical literature between 2018 and 2025. Messenger RNA (mRNA)-based vaccines have demonstrated strong immunogenicity and practical efficacy in the real world, as well as varying safety profiles across platforms and the potential of new modalities that will be developed both to treat infectious diseases and to be applied in other contexts. The discussion also dwells upon the flexibility of regulation, unequal distribution, and surveillance-based pharmacovigilance. This review can be used to compile a thoroughly comparative view of modern vaccines, based on bringing together mechanistic insights and implementation barriers, which can guide future innovation and policy reconciliation and global resilience. It makes inferences in support of the more progressive, equity-based paradigm of pandemic preparedness and immunization strategy in the 21st century. This review highlights how mRNA technology has transformed the landscape of vaccinology, offering a foundation for faster, safer, and more equitable global immunization strategies in the post-pandemic era.}, }

Rural older adults, a uniquely vulnerable population, face barriers to accessing these tools due to rurality and usability challenges. Although a growing body of literature examines the acceptability and usability of digital tools among rural older adults, no study has synthesized this research to establish best practices.<br><br>OBJECTIVE: This study aims to review existing literature on digital health tools for rural older adults, highlighting key lessons learned about their acceptability and identifying strategies to improve usability for this population.<br><br>METHODS: Following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, this study reviewed literature that investigated the role of digital health tools on the health outcomes of rural older adults (ie, at least 60 years old). The literature was retrieved from 5 electronic databases through June 2023. This study and all reviewed literature were conducted in the United States. Guided by a systematic process, 2 reviewers assessed relevant articles for eligibility, analyzed data, and extracted relevant content. The extracted findings were organized according to the evidence-based technology acceptance model, which assesses the acceptability of a technology by its usefulness, ease of use, and intention to use.<br><br>RESULTS: The preliminary title review produced 7728 results, and 38 eligible manuscripts were included in the final review. Studies included both rural older adults and providers of rural older adults as participants. Digital health tools included, but were not limited to, videoconferencing, phone calls, telehealth monitoring, telemedicine appointments, and computer-based interventions. Findings on the usefulness of digital health tools by rural older adults were mixed. While digital health tools were useful for overcoming barriers to accessing care, these tools were less useful for rural older adults with limited digital literacy. Additionally, some studies described that the technology was easy but difficult to use when faced with environmental barriers, equipment issues, and discomfort with the technology. Rural older adults often reported an intention to use the technology after the study. Yet, on a few occasions, participants who preferred in-person care visits or did not have buy-in on the technology reported no intention to use the technology again.<br><br>CONCLUSIONS: Our review highlights that rural older adults and their providers generally view digital health tools as acceptable for delivering care and, in some cases, as a viable alternative to in-person clinic visits. While certain barriers impacted the acceptance of these tools among rural older adults, many of these challenges were not directly linked to their age or rural location; thus, they are potentially applicable to urban older adults.<br><br>TRIAL REGISTRATION: PROSPERO CRD42021287924; https://www.crd.york.ac.uk/PROSPERO/view/CRD42021287924.}, }

MicroRNAs (miRNAs) have emerged as critical regulators of host pathogen interactions by modulating innate immunity, inflammatory signaling, and viral replication. This review focuses on respiratory RNA and DNA viruses that primarily infect the airways, including influenza viruses, RSV, human metapneumovirus, rhinoviruses, adenoviruses, and SARS-CoV-2. Several miRNAs, including miR-155 and miR-146a, are upregulated during infections with SARS-CoV-2, influenza, and RSV, where they fine-tune interferon and NF-κB signaling pathways. In contrast, downregulation of miR-21, miR-223, and let-7 family members has been linked to enhanced viral replication and dysregulated immune responses. Moreover, miR-122, miR-29a, and miR-124 have gained attention as potential therapeutic targets or prognostic biomarkers due to their roles in modulating viral load, cytokine production, and tissue injury. This review synthesizes current evidence on miRNA-mediated regulation of respiratory viruses, evaluates their promise as therapeutic candidates and diagnostic tools, and discusses delivery systems designed for targeted miRNA modulation. Despite promising advances, challenges remain in achieving tissue-specific delivery, avoiding immune off-target effects, and validating efficacy in clinical settings. Most of the available data are derived from in vitro or animal models and heterogeneous clinical cohorts, so conclusions about causality and therapeutic efficacy should be viewed as provisional and highlight significant translational gaps. Finally, we outline major challenges and future research directions needed to translate miRNA-targeted therapies into clinically viable antiviral strategies. Insights from these emerging studies position miRNA-targeted interventions as a potential new class of antiviral therapeutics and underscore the need for rigorous, translational research to realize their clinical utility.}, }

Recent studies suggest that alterations in gut microbiota can influence disease progression, immune responses, and clinical outcomes. The bidirectional relationship between the gut microbiota and the host immune system is crucial in shaping responses to infection. Furthermore, dysbiosis has been linked to exacerbated inflammation, impaired mucosal barrier function, and altered drug metabolism, thereby complicating both disease pathogenesis and treatment efficacy. This review examines the interplay between viral infections and gut microbiota dysbiosis, with a focus on the underlying mechanisms and potential therapeutic strategies to modulate host immunity. We also evaluate the potential of microbiome-based interventions, such as probiotics, prebiotics, and fecal microbiota transplantation, as therapeutic strategies for restoring microbial balance and mitigating the severity of infections. The paper underscores the need for further research to optimize microbiota-targeted therapies and integrate them into clinical practice, offering a comprehensive approach to managing dysbiosis in viral infectious diseases.}, }

We synthesized evidence suggesting that LC arises from intersecting pathways including viral persistence, intestinal dysbiosis and barrier compromise with microbial translocation, innate immune activation with neutrophil extracellular traps (NET) and thromboinflammation, and immune dysregulation with features of exhaustion and autoimmunity. These processes adversely impact blood-brain barrier (BBB) function and lead to neuroinflammation. We propose a mechanistic model in which viral antigens and translocated microbial products amplify pro-inflammatory networks promoting immunothrombosis and tissue hypoperfusion. Hematogenous and gut-brain pathways may then deliver inflammatory mediators to the central nervous system (CNS), resulting in BBB disruption and glial activation that underpin nervous system disorders in LC. Treatment regimens aimed at lowering antigen load, restoring mucosal barrier integrity and modulating myeloid/coagulation pathways may warrant investigation as novel therapeutic strategies to treat LC.}, }

The combined prevalence rate of CFS was 45.2% after 4 weeks in patients with novel coronavirus. Women, people over 40 years of age, and low-income people are susceptible groups, which have a significant impact on immune, nervous, endocrine, and other system functions. First, from the perspective of epidemiology, this paper reviews the global epidemic trend of CFS, the differences in incidence and prevalence in different regions and populations, and risk factors such as heredity, infection, and childhood trauma. Second, the development of diagnostic techniques for CFS, including the evolution of clinical diagnostic criteria, research progress on immune and metabolic biomarkers, and the application of MRI and other imaging techniques in the diagnosis of CFS, is described, followed by an in-depth discussion of the genetics of CFS, including genetic susceptibility, genomic association, and familial aggregation. The pathophysiological mechanism of CFS was also analyzed, revealing abnormalities in NK cell function and immune factors in the immune system, dysfunction of the hypothalamic-pituitary-adrenal axis in the neuroendocrine system, and disorders of energy and lipid metabolism in the metabolic system. This paper focuses on the study of acupuncture and moxibustion treatment of CFS, traces back to the historical application of acupuncture and moxibustion treatment of CFS, analyzes the relationship between the pathological mechanism of CFS and acupuncture and moxibustion intervention, expounds the theoretical basis of traditional Chinese medicine and modern mechanism of action of acupuncture and moxibustion treatment, and introduces the results of clinical trials, efficacy evaluation methods, and individualized treatment strategies for acupuncture and moxibustion treatment of CFS. The innovative application of acupuncture techniques, such as electroacupuncture and acupoint catgut embedding, as well as the synergistic effect of acupuncture combined with traditional Chinese medicine and psychotherapy, are shown. At the same time, disputes and challenges in the efficacy, safety, and ethics of acupuncture treatment for CFS were pointed out, and future research directions, potential breakthroughs, and international cooperation opportunities of acupuncture treatment for CFS are discussed.

In the absence of specific drugs and vaccines for controlling SEVs in the pig production, this review summarizes the inhibitory effects of natural products against these major porcine enteric viruses. Specifically, it focuses on recent studies regarding the anti-SEVS activities of traditional Chinese medicine (TCM) compound formulas, herbal extracts, pharmaceutical monomers, and natural metabolites. The review elaborates on how these natural products exert antiviral activities against SEVs, highlighting their potential as alternative or complementary agents for controlling porcine enteric viral infections.

Epidemiological surveillance indicates that Streptococcus pneumoniae remains the most frequent etiological agent and the leading cause of mortality. However, with the advent of new diagnostic techniques, viral etiology has gained priority. Chest X-ray is considered mandatory to confirm the diagnosis and establish the spread. Microbiological, antigen, molecular, biomarker, and carriage tests have specific indications and a role to play in reconsidering empirical treatments. Severity scales are useful for defining the site of care, and the most validated prognostic models are PSI and CURB-65. When antibacterial treatment is appropriate, aminopenicillins ± beta-lactamase inhibitors are the preferred treatment, with the addition of a macrolide in severe cases. Pseudomonas and methicillin-resistant Staphylococcus aureus should be considered primarily in patients with a history of prior infection/colonization or severe structural lung disease. Shortened courses have gained support in the literature, and once clinical stability is achieved, it is suggested that treatment be continued for 3-5 days for CAP managed in an outpatient/general ward setting, and 5-7 days for CAP requiring intensive care. The role of corticosteroids in reducing mortality has been documented in severe forms. The benefit of neuraminidase inhibitors for influenza is of low certainty and relatively marginal. Treatments that have had an impact on reducing mortality from severe-critical COVID-19 are corticosteroids, IL-6 receptor blockers, and baricitinib.}, }

Since pregnant and breastfeeding women are often excluded from clinical vaccine trials, including those assessing toxicity, there is limited knowledge about this vulnerable population and their offspring. In this context, preclinical studies designed to assess the effects of vaccine and therapeutic candidates on reproduction and development must rely on in vivo models that accurately replicate key aspects of the pathogenesis observed in human disease. When evaluating the reproductive toxicity of vaccines, it is essential not only to assess potential effects on fertility, embryogenesis, development, and reproduction, but also to consider the interactions of the vaccine with the immune system of both the mother and her offspring.

The latter condition gained international attention during the rollout of vaccines against SARS-CoV-2. Since then, an increased awareness for anti-PF4 mediated disorders arose and patients were recognized with anti-PF4 disorders occurring without prior heparin or adenoviral vector vaccine exposure. These disorders include various acute and chronic VITT-like conditions, i.e. post-viral VITT, diaplacentally transmitted anti-PF4 antibodies in neonatal stroke, monoclonal gammopathies of thrombotic significance (MGTS) and chronic autoimmune VITT of unknown origin. All anti-PF4 related disorders share key serological and immunopathological features with VITT, such as the formation of immune complexes and platelet activation via the Fcγ receptor IIA (FcγRIIA). Via their activation, platelets form procoagulant, aggregatory and secretory phenotypes shaping their interplay with neutrophils, monocytes, and coagulation factors to amplify thrombotic responses. Integrating recent mechanistic insights, clinical observations and diagnostic developments, this review proposes an updated conceptual framework for anti PF4-related immunothrombosis. We aim to raise awareness among clinicians and researchers, to promote early diagnosis and encourage further translational research towards improved therapeutic strategies in this clinically significant area.}, }

A trial sequential analysis was conducted for mortality and pressure injuries.<br><br>RESULTS: Seven studies (six observational and one RCT) involving 996 patients (592 prolonged and 404 standard) were included in the study. Prolonged prone positioning showed a nonsignificant trend towards lower mortality (33.8% vs. 39.8%, RR: 0.81, 95% confidence interval: 0.60-1.09; P = 0.16) and a borderline increase in pressure injuries (30.2% vs. 26.2%; relative risk (RR) 1.27, 95% confidence interval: 1.00-1.62; P = 0.05).

The multifactorial pathophysiology underlying PASC remains incompletely understood, limiting the development of effective management strategies. Increasing evidence suggests that both immune dysregulation and hemostatic imbalance play central roles in post-COVID-19 complications. Megakaryocytes, key regulators of platelet production and coagulation, have emerged as potential contributors to sustained thrombo-inflammatory processes following SARS-CoV-2 infection. In parallel, afucosylated IgG antibodies have been strongly implicated in exaggerated immune activation and hyperinflammatory responses during acute COVID-19. The persistence of such antibody glycosylation patterns beyond the acute phase raises the possibility that they may also contribute to chronic immune and vascular alterations observed in PASC. This narrative review explores the potential interplay between megakaryocyte dysfunction and afucosylated IgG antibodies in the pathogenesis of PASC. By examining mechanisms identified during acute SARS-CoV-2 infection, we discuss how prolonged immune-hemostatic crosstalk may promote persistent inflammation, endothelial dysfunction, and microvascular abnormalities. Understanding these interconnected pathways may provide mechanistic insight into the heterogeneity of PASC manifestations and help identify novel therapeutic targets for long-term post-COVID-19 sequelae.}, }

It continues to be a major contributor to global disease, and death, with low- and middle-income countries (LMICs) experiencing a disproportionate impact. India, as one of the largest LMICs, plays a significant role in global COPD-related mortality and disability-adjusted life years (DALYs). In India, COPD continues to be underrecognized owing to limited spirometry availability, inconsistent diagnostic approaches, and weak surveillance systems. Previous prevalence estimates are both outdated and methodologically inconsistent, while the COVID-19 pandemic may have further shifted disease trends. This systematic review and meta-analysis seeks to bridge these gaps by delivering current, standardized, and comprehensive prevalence data.<br><br>OBJECTIVE: To estimate the pooled prevalence of spirometry-confirmed COPD among Indian adults and identify key demographic and environmental correlates through a systematic review and meta-analysis of observational studies.<br><br>METHODS: This systematic review and meta-analysis aimed to determine the prevalence of spirometry-confirmed COPD among Indian adults. The study was registered in PROSPERO (CRD420251140678) and conducted in accordance with PRISMA guidelines. Literature searches were carried out in PubMed, EMBASE, Scopus, and Web of Science up to June 9, 2025, using relevant MeSH terms and keywords on COPD, prevalence, and India. Eligible studies included observational designs reporting spirometry-based COPD prevalence in adults; studies relying on non-spirometry diagnosis, qualitative designs, interventions, or non-English publications were excluded. Three reviewers independently screened records, extracted study and population data, and evaluated methodological quality using the Joanna Briggs Institute (JBI) checklist. Pooled prevalence was calculated using a random-effects model. Heterogeneity was assessed with I[2] and Cochran&#x2019;s Q, complemented by Baujat and Galbraith plots. Subgroup and sensitivity analyses examined variations by diagnostic criteria, demographics, and exposures, while publication bias was tested using funnel plots, Egger&#x2019;s and Begg&#x2019;s methods, and trim-and-fill analysis.<br><br>RESULTS: Twenty-three studies comprising 27,319 Indian adults were included. The pooled prevalence of COPD was 13% (95% CI: 9%&#x2013;18%), with substantial heterogeneity (I[2]&#x2009;=&#x2009;99.8%). Higher prevalence was observed among smokers (37%), elderly adults (&#x2265;&#x2009;60&#xa0;years: 27%), males (16%), and biomass fuel users (8%). Studies using GOLD criteria reported a higher prevalence (15%) than those using FEV&#x2081;/FVC&#x2009;<&#x2009;LLN (10%). Hospital-based studies showed a greater prevalence (27%) than community-based ones (12%). Regional variation was notable, with North India reporting the highest prevalence (19%) and West India the lowest (7%). Sensitivity analyses confirmed the robustness of findings; publication bias was minimal and did not significantly affect pooled estimates.<br><br>CONCLUSION: COPD remains a significant and underrecognized public health challenge in India. As all included studies were appraised as good quality using the JBI tool, the evidence base is strong and supports reliable pooled estimates. Therefore, our conclusions emphasize the importance of routine spirometry-based screening, targeted interventions for high-risk groups, and integration of COPD surveillance into India&#x2019;s NCD framework, while reinforcing gender-sensitive strategies and clean fuel initiatives as evidence-based measures to reduce disease burden and guide policy planning.<br><br>SUPPLEMENTARY INFORMATION: The online version contains supplementary material available at 10.1186/s12890-026-04134-0.}, }

Even before the pandemic, certain traditional vaccines (such as BCG) demonstrated "cross-protection" effects beyond their target diseases. The trained immunity (TRIM) theory offers a promising path to develop broad-spectrum, effective, and durable vaccines. This review summarizes core advances in TRIM within vaccinology, systematically outlining vaccine design strategies based on this concept for the first time. These strategies encompass vaccine-mediated cross-protection, methods to enhance vaccine potency and persistence, pathways to achieve broad-spectrum effects, and regulatory characteristics involving immune recognition, antigen delivery, safety, and tolerability. This study explores the synergistic effects and application prospects of TRIM adjuvants such as β-glucan and Toll-like receptor (TLR) agonists. The impact of transgenerational immune effects on offspring immune function provides a crucial direction for future research. It also highlights current limitations in studies regarding persistence, individual variability, and risks of excessive inflammation. Existing vaccines capable of inducing TRIM will inspire next-generation vaccine development. Innovative applications of this vaccine category can propel the advancement of trained immunity-based vaccines (TIbVs). This review proposes an innovative approach─the "Vaccine Immunity Foundation Hypothesis." This lays the groundwork for designing next-generation vaccines and advancing the clinical translation of TRIM therapies, establishing a theoretical foundation for developing broad-spectrum, highly effective, durable, and safe immune protection strategies.}, }

Despite significant advances, mRNA remains inherently unstable under physiological conditions due to its susceptibility to degradation by ubiquitous ribonucleases and physicochemical factors, making its storage, transport and clinical application challenging. This review explores the critical determinants influencing mRNA stability and discusses how chemical engineering strategies are suited to enhance mRNA stability, including 5' cap modification, poly(A) tail engineering, optimization of untranslated regions, as well as coding sequence refinements, reversible 2'-OH acylation, the development of circular RNA constructs and self-amplifying RNA systems. We also discuss efforts towards mRNA immunogenicity regulation and advanced mRNA delivery systems, along with progress in storage and transport solutions, which have further contributed to addressing stability concerns. Finally, we discuss the remaining challenges in clinical translation and provide forward-looking perspectives on emerging mRNA-based technologies.}, }

Family-Centered Care (FCC), which ensures parental presence and participation, is recognized as the standard of practice to mitigate psychological distress and trauma in critically ill children. However, infection control mandates [most notably during the coronavirus disease 2019 (COVID-19) pandemic] and resource limitations often necessitate restrictive visitation policies, leaving children in an "unaccompanied" state. This separation from parents constitutes a significant deviation from the standard care model and poses a unique psychological risk. A systematic synthesis of the specific psychological impacts of this parental absence and adaptive strategies to effectively intervene within this context remains underdeveloped. This narrative review aims to analyze the primary psychological consequences of parental absence for children in the PICU and to explore the intervention strategies adapted to mitigate these effects.<br><br>METHODS: We reviewed journal articles from the past 15 years (2010-2024) that analyze and discuss the psychological impact and intervention strategies of unaccompanied patients in pediatric intensive care units.<br><br>KEY CONTENT AND FINDINGS: Our analysis indicates that an unaccompanied state is a significant, independent risk factor for psychological morbidity in PICU patients, markedly exacerbating separation anxiety, fear, loneliness, and depressive symptoms, which may also impede physiological recovery. Effective interventions must focus on mitigating the trauma of separation. The core strategy identified is "Virtual Family-Centered Care" (e.g., re-establishing family connection and participation in rounds via video technology). Other critical interventions include alternative socio-emotional support from the healthcare team (especially Child Life Specialists), professional psychological therapies, and environmental optimization to reduce threat perception.<br><br>CONCLUSIONS: We conclude that while parental presence is irreplaceable, PICUs must adopt innovative interventions, particularly technology-assisted virtual connections, to protect the psychological well-being of unaccompanied children whenever visitation is necessarily restricted.}, }

This study employs a systematic analysis method based on clinical trial registries to conduct a descriptive statistical analysis of mRNA vaccine-related trials registered in the ClinicalTrials.gov database from March 2000 to July 2025. We compared characteristics such as the number of trials, geographical distribution, study type, funding sources, trial design, and indications, and used chi-square tests and Fisher's exact tests for inter-group difference analysis. The results show that the number of mRNA vaccine clinical trials has experienced explosive growth after the pandemic, presenting obvious pandemic-driven characteristics and geographical differences. There are significant differences in registration characteristics and trial design among China, the United States, and Europe (p<0.01). Indications have rapidly expanded from infectious diseases to multiple fields such as tumors, autoimmune diseases, and metabolic diseases, indicating that mRNA technology is transforming from an infectious disease prevention tool into a platform technology with broad therapeutic potential. From the perspective of clinical trial registration, this study provides empirical evidence for understanding the global research status, regional strategy differences, and future development directions of mRNA vaccines. It offers insights for vaccine development planning, international regulatory coordination, and global clinical trial strategic planning, assisting researchers, enterprises, and policymakers in making optimal decisions.}, }

It is important to attempt to reduce the growth of this trend, especially among susceptible individuals, considering that it increased because of the COVID-19 pandemic. Natural language processing (NLP) provides various tools that allow for the analysis of texts to predict the presence of suicidal ideation. This work aims to conduct a systematic literature review to extract the computational techniques for identifying suicidal ideation in texts written in natural language.<br><br>METHODS: The PRISMA 2020 method was used, which was divided into nine phases, and three inclusion criteria and two exclusion criteria were established for the selection of studies. The searches were conducted through high-level academic databases such as Scopus, IEEE Xplore, ACM Digital Library, Springer, and Web of Science. The risk of bias was assessed using AMSTAR 2. Potential biases identified include a lack of linguistic and cultural diversity and the predominance of data from social networks. A narrative synthesis was used to analyze and compare the findings qualitatively.<br><br>RESULTS: In the end, 25 studies related to computational methods for detecting suicidal ideation in texts written in natural language were identified. The techniques mainly focus on transformer-based models such as BERT and hybrid methods, which combine this architecture with neural networks such as CNN and LSTM. There are also approaches with hierarchical attention mechanisms. Some studies employed additional techniques such as feature extraction with TF-IDF and pre-trained embeddings to improve model performance.<br><br>DISCUSSION: Limitations in the evidence include the lack of linguistic and cultural diversity and the predominance of data from social networks. These results indicate that computational techniques have high potential to support early prevention strategies for suicidal ideation. However, expanding the diversity of linguistic contexts and improving understanding of the models among non-experts, such as physicians and other interested individuals, is necessary.}, }

A comprehensive search of PubMed, Scopus, Web of Science, and Google Scholar identified 13 eligible case reports published between 2020 and 2024. Because all available evidence consisted solely of individual case descriptions without comparator groups, the review followed PRISMA 2020 guidelines and employed qualitative narrative synthesis rather than meta-analysis. Across the included cases, patients consistently presented with hallmark features of AOSD, including high spiking fever, arthritis or arthralgia, markedly elevated ferritin levels, and, in several instances, the characteristic salmon-colored rash. Symptom onset typically occurred within four to fifteen days following vaccination. Although these cases demonstrate recognisable clinical patterns, the absence of denominator data, lack of population-based studies, and inherent publication bias prevent estimation of incidence or risk, and no causal relationship with vaccination can be inferred. All reported patients responded favorably to corticosteroids, with some requiring biologic therapy for disease control. These findings highlight the importance of clinician awareness when evaluating persistent febrile or inflammatory symptoms in recently vaccinated individuals, while emphasising that COVID-19 vaccination remains overwhelmingly safe. Larger registries, pharmacovigilance data, and controlled studies are needed to clarify potential risk factors and guide future revaccination decisions.}, }

Through specific examples of implemented programmes, including the NHS Diabetes Prevention Programme and the NHS Type 2 Diabetes Path to Remission Programme, I highlight important fundamental principles when making the case for, and implementing, national policy. First, ensure granular data collection to support evaluation and exploit data linkages to harness the power of real-world datasets. Second, where good evidence exists, implement evidence-based policy; where good evidence does not exist but political pressures to implement are being brought to bear, pilot and evaluate. Third, when the opportunity arises, rapidly translate new high-quality evidence into policy and practice. And fourth, support and protect the workload of healthcare professionals, particularly of those working in primary care. Then, through an epidemiological lens, I highlight: how the COVID-19 pandemic further unlocked the potential of national routinely collected electronic healthcare datasets; how, through application of these datasets, it has been possible to demonstrate improvements in diabetes complications and mortality through routine care delivery; and how it has been possible to demonstrate the next epidemiological transition in the global diabetes epidemic to multimorbidity/multiple long-term conditions.}, }

In the current COVID-19 global health crisis, achieving a better understanding of the aging immune system proves to be an imperative step in preventing and treating respiratory viral infections in older patients. Furthermore, many common respiratory viruses infecting older adults, including human metapneumovirus and parainfluenza virus, do not have licensed vaccines, thereby increasing the risk of severe infection in the aged host. Moreover, given the slowed immune response of older adults, vaccine efficacy for respiratory viruses such as influenza in older adults is minimal, indicating the need to develop more potent vaccines. A better understanding of the aging immune system would allow vaccines to target immunological deficits in the aged host. Three aspects of the aging immune system affect the response to respiratory viruses and vaccines: [1] innate immunity [2], the “inflammaging” hypothesis, and [3] the adaptive immune response. Several innate immune cells (neutrophils, macrophages, dendritic cells, and natural killer cells) as well as adaptive immune cells (T and B lymphocytes) exhibit significant functional impairment in older adults. The inflammaging hypothesis bridges the innate and adaptive arms of the immune system.

Although travel enhances global interactions, it also poses risks to public health through the potential transmission of diseases. The rapid global transmission of infectious diseases, exemplified by the outbreaks of COVID-19 and Zika virus, underscores the critical need for in-depth research into travel-associated disease dissemination. When individuals travel, they are exposed to a variety of diverse microbial environments, which can affect their healthy microbiome. In this review, we introduce the concept of "travel microbiota" to encapsulate the dynamic shifts in human microbial communities induced by travel across different transportation modes. This disruption can affect metabolic and immune functions and potentially facilitate the spread of diseases. Given these implications, it is crucial to investigate how different modes of transportation affect the human microbiota. Our study reviews the impact of travel on the human microbiota, highlighting differences across transportation modes. The objective is to establish a framework for understanding travel health and the role of microbiota in managing travel-related health risks. A comprehensive understanding of this relationship is essential for developing preventive strategies to safeguard and restore the human microbiota.<br><br>METHODS: To provide the specific content, relevant publications were identified on Google Scholar, PubMed, and Science Direct using specific keywords such as dysbiosis, gut, health, microbiome, microbiota, pathogens, travel, and transportation. We did not add any limits to the publication date during the inclusion of papers. However, it is noteworthy that the initial reports, including the aforementioned keywords, have been published starting from 2015.<br><br>CONCLUSION: Travel has a profound impact on the human microbiota, and it is essential to consider the implications associated with various modes of transportation. Traveling through various modes of transportation, such as roadways, airways, and maritime, has significantly influenced human microbiota. Moreover, it acts as a dynamic interface for microbial exchange driving rapid shift in microbial diversity, community convergence, and the diversification of resistant genes. However, the underlying mechanism of these changes remains elusive. By integrating evidence across multiple modes of transportation, this review highlights travel as an underrecognized determinant of microbiome variability and introduces the term "Travel microbiota". Moreover, this review is pivotal for understanding the ways in which travel alters microbial diversity and developing effective interventions. It is imperative to conduct future research that focuses on conducting large-scale longitudinal studies to assess the effects of traveling on microbial composition and to develop potential preventive measures.}, }

These symptoms are characterized by the triumvirate of post-acute COVID-19 (vaccination) syndrome symptoms: post-exertional malaise, fatigue, and cognitive impairment, commonly referred to as brain fog. These symptoms can be recreated through perturbations that disrupt mitochondria, and spike protein has been observed to disrupt mitochondria in vitro, providing mechanistic support for this relationship. Post-acute COVID-19 (vaccination) syndrome patients suffer from a severely decreased lactate threshold and can experience symptoms of overexertion even at low power output. Furthermore, biopsies have revealed disrupted mitochondria, and energetics and physiological studies have shown that lipid oxidation constitutes a significantly reduced fraction of total energy production/consumption in post-acute COVID-19 (vaccination) syndrome patients. This review explores the therapeutic axes of lactate, carbon dioxide, and fatty acid oxidation for resolving the energy production challenges in post-acute COVID-19 (vaccination) syndrome, suggesting interventions that increase the lactate threshold, increase tissue oxygenation (paradoxically through increasing partial pressure of CO2), and increase the rates at which lipids are oxidized relative to carbohydrates. Analogies from the world of exercise science are introduced, comparing post-acute COVID-19 (vaccination) syndrome to an overabundance of fast-twitch muscle fibers, with oxygenation similar to that experienced at high altitude, and presenting as an inverse 'fat adaptation' phenomenon, as observed in endurance athletes, especially those adopting low-carbohydrate diets.}, }

MIS-C is characterized by inflammation in several organ systems, including the heart, lungs, kidneys, brain, skin, and eyes. Although MIS-C symptoms can vary widely, typical symptoms include fever, stomach ache, nausea, vomiting, diarrhea, rash, red eyes, and exhaustion. Although the pathogenesis of MIS-C is not yet fully understood, studies have shown that an uncontrolled immunological response known as a "cytokine storm" may play a role in the development of MIS-C. Several studies have related micronutrient deficiencies to chronic immunological activation, increased inflammation, increased cytokine production, and increased chance of developing a persistent viral infection. Studies have shown that children with MIS-C had lower micronutrients, including vitamin D, C, and zinc, than do healthy kids. Deficits in these nutrients, which are crucial for controlling the immunological response, may make the immune system less able to fight off infections and cause MIS-C. In conclusion, research on the connection between MIS-C and micronutrient deficiencies is still in its early stages. Although there is some evidence linking the two, additional research is required to determine a cause and effect.}, }

Although the clinical presentation and diagnostic criteria are widely established, the precise mechanisms underlying GBS are complex and poorly understood. This review summarizes current literature on the interplay of post-infectious triggers, molecular mimicry, and host susceptibility as influenced by genetic and epigenetic variables. Infectious pathogens such as Campylobacter jejuni, cytomegalovirus, Epstein-Barr virus, and, more recently, Zika and SARS-CoV-2 operate as initiators via molecular mimicry, in which pathogen antigens imitate peripheral nerve components, triggering the formation of autoreactive antibody and T-cell responses. Acute inflammatory demyelinating polyneuropathy (AIDP) is characterized by demyelination and inflammatory cytokine responses, whereas acute motor axonal neuropathy (AMAN) is associated with ganglioside-targeting antibodies and axonal loss. Genetic polymorphisms, such as those in HLA, TLR4, MMP9, and CD1A, influence vulnerability to the disease and its progression. Given that many patients experience persistent sensory, motor, and autonomic dysfunction despite treatment, the identification of long-term complications highlights the necessity of customized rehabilitation and long-term follow-up. Traditional therapeutic techniques, such as plasma exchange and intravenous immunoglobulin, remain in use, but current trials on complement inhibitors, antibody-degrading enzymes, and mesenchymal stem cell therapies indicate a move toward mechanism-driven approaches.

While bacterial pathogens such as Porphyromonas gingivalis are well-known contributors, emerging evidence indicates the role of viruses, especially herpesviruses, in the onset and progression of periodontal tissue destruction. In this review, the interplay between viral infections and periodontal health was explored, with an emphasis on the immunopathological mechanisms in which different viruses such as human herpesvirus, Epstein-Barr virus, and human cytomegalovirus aggravate periodontal tissue destruction. These viruses impair host defenses, promote bacterial colonization, and alter cytokine responses, leading to periodontal tissue damage. The review also addresses the impact of systemic viral infections, such as HIV and COVID-19, on periodontal diseases. Elevation in inflammatory mediators, including interleukin-6, link periodontitis with adverse clinical outcomes in viral infections. Moreover, interactions between P. gingivalis and respiratory viruses suggest oral pathogens may also influence systemic disease severity. Advances in diagnosis using molecular technology have improved viral detection in periodontal tissues, and previous studies support the use of antiviral therapies and gene-targeted interventions as potential adjuncts to traditional periodontal care.

Emerging evidence demonstrates that spike protein-mediated effects, independent of productive viral infection, disrupt endothelial homeostasis through angiotensin-converting enzyme 2 (ACE2) dysregulation, integrin engagement, altered calcium signaling, junctional protein remodeling, oxidative stress, and pro-inflammatory and pro-apoptotic pathways. This review is intentionally focused on spike (S) protein-driven mechanisms of endothelial dysfunction; pathogenic vascular effects attributed to other SARS-CoV-2 structural proteins, including the nucleocapsid (N) protein, are beyond the scope of this discussion.

Recently, research has emphasized the importance of hematological parameters associated with inflammation, which can be easily analyzed through routine blood tests. Combining these parameters may have predictive value for various diseases, including pulmonary tuberculosis and even help monitor the effectiveness of treatment. Since there is no single hematological or inflammatory biomarker that provides precise and dynamic information about the success or failure of treatment, identifying individual markers or sets of biomarkers with higher sensitivity and specificity is essential. This is particularly important since sputum culture conversion at two months remains insufficiently sensitive and microscopy conversion has limited sensitivity and specificity in detecting treatment failure. Also, the analysis of the impact of the standard directly observed treatment, short-course regimen on pathogenic mechanisms also focuses on how it influences the interaction between inflammation and oxidative tissue degradation, by measuring plasma levels of glutathione. Utilizing a combination of hematological, inflammatory, and antioxidant biomarkers offers significant insights into systemic inflammatory responses in pulmonary tuberculosis patients, both before commencing treatment and during the entire duration of antituberculosis therapy. Combining different inflammatory parameters into a multiple biomarker can significantly enhance the accuracy of predicting prognosis and response to antibiotic chemotherapy. Identifying an optimal combination of biomarkers with predictive value is crucial for assessing treatment response and evaluating the effectiveness of anti-TB medication. Rather than developing or testing a composite prediction model, this review summarizes reported performance metrics from individual studies and highlights priorities for future prospective validation of integrated biomarker panels.}, }

Published studies describing dermatologic findings in patients aged 0-18 years were reviewed. The analysis revealed a broad heterogeneity of skin manifestations in both conditions, ranging from classic polymorphous rash and acral erythema to atypical presentations, including annular, psoriasiform, vesiculobullous, urticarial, and erythema nodosum-like lesions. Reactivation at Bacillus Calmette-Guérin vaccination sites and associated mucocutaneous findings, such as conjunctivitis and oral changes, emerged as supportive diagnostic clues, particularly for incomplete KD. Considerable overlap in cutaneous phenotypes between KD and MIS-C was observed, especially in patients with persistent fever and systemic inflammation, highlighting the risk of diagnostic delay. These findings underscore the importance of recognizing atypical dermatologic patterns as part of an integrated diagnostic approach, as delayed identification may increase the risk of cardiovascular complications.

This review analyzes more than 100 PLpro-ligand co-crystal structures and summarizes the major binding modes between these ligands and PLpro. Most of these ligands bind to sites analogous to those targeted by the classical non-covalent inhibitor GRL0617, primarily involving the P3 and P4 subsites and the BL2 loop. Based on these structural insights, optimized inhibitors have expanded targeting beyond the canonical binding site to auxiliary regions such as the BL2 groove and the Val70 site, and in some cases toward the catalytic Cys111 buried within a narrow pocket. Certain ligands identified through various screening approaches bind to non-canonical or allosteric regions, such as the S1 and S2 sites or the zinc-finger domain, engaging PLpro through distinct interaction modes and thereby offering additional opportunities for PLpro inhibitor design. The review also discusses potential strategies for future PLpro inhibitor development informed by recent structural advances. Taken together, these structural and functional insights support ongoing efforts in the structure-guided design and optimization of PLpro inhibitors.}, }

These characteristics frequently compromise the durability of existing vaccines and antiviral therapies, highlighting the urgent need for new antiviral agents. Alkaloids, a structurally diverse class of nitrogen-containing natural compounds, have gained attention for their ability to interfere with multiple stages of the viral life cycle, including entry, replication, protein synthesis, and host immune modulation. To our knowledge, this review compiles all currently reported alkaloids with antiviral activity against RNA viruses and summarizes their proposed mechanisms of action, distinguishing evidence from in vitro, in vivo, and in silico studies. Quaternary alkaloids are discussed separately because their permanent ionic charge enables distinctive interactions with membranes and host pathways. Although many findings are promising, clinical translation remains limited by incomplete mechanistic validation, scarce in vivo data, suboptimal bioavailability, narrow therapeutic windows, and inconsistent experimental methodologies. To advance the field, future research should prioritize RT-qPCR-based antiviral evaluation to accurately quantify viral replication, incorporate mechanistic assays to clarify modes of action, apply structure-activity relationship (SAR) approaches for rational optimization, and expand in vivo pharmacokinetic and efficacy studies to assess therapeutic feasibility. Overall, alkaloids represent a promising yet underdeveloped reservoir for next-generation antiviral discovery against rapidly evolving RNA viruses.}, }

Emerging evidence suggests that the linkage between audiovestibular dysfunction and long COVID-19 syndrome might rely on (a) direct inner ear system damage related to viral invasion and consequent inflammation, (b) micro thromboembolic events, which might result from the COVID-19-induced autoimmune reaction against endothelial cells, and consequent transient-ischemia and hypoxia of the auditory pathways, (c) the disturbed nerve conduction in vestibulocochlear nerves due to viral invasion, and finally (d) altered auditory cortex function, either imbalanced central gain or neurotransmitter disturbance. However, most of the aforementioned mechanism remained hypothetic and still needed further studies to approve or refute. This systematic review synthesizes current evidence on the characteristics, pathophysiology, diagnostic approaches, and management of audiovestibular dysfunction related to long COVID-19 syndrome.

HR-HPV prevalence in men is high, with global estimates of 21% for male genital infections. While the HPV vaccination programme has expanded to include boys, challenges remain, including a decline in vaccine uptake due to COVID-19 disruptions, vaccine hesitancy, and misinformation. These barriers hinder the full potential of vaccination efforts.

We suggest a more inclusive approach to HPV prevention, emphasising the need for targeted vaccination and screening programs for men. A gender-neutral approach is crucial to reducing the global burden of HPV-related diseases and moving closer to the goal of eradicating HPV infections worldwide.}, }

This paper aims to systematically review the longitudinal relationship between loneliness and psychosis spectrum continuum, addressing two fundamental questions: (1) is loneliness a risk factor for the development of psychosis, and (2) does psychosis increase the risk of experiencing loneliness?<br><br>STUDY DESIGN: A comprehensive search of 5 electronic databases yielded a total of 4386 records, from which 10 observational studies were finally included.<br><br>STUDY RESULTS: Six studies investigated the first research question, and all of them identified a significant association between loneliness and the subsequent incidence of psychosis (question 1). Conversely, 4 studies explored the second research question, with 3 suggesting that individuals within the psychosis spectrum may face heightened susceptibility to loneliness (question 2). The remaining study, conducted during the COVID-19 pandemic, did not yield significant findings. Assessment of methodological quality indicated predominantly moderate-to-high-quality studies.<br><br>CONCLUSIONS: The findings underscore the need for further research, particularly longitudinal prospective studies, to clarify whether the observed association between loneliness and psychosis is direct or whether it is instead moderated or mediated by other variables. Overall, the available evidence provides stronger support for loneliness as a potential risk factor for the onset of psychosis, although the number of longitudinal studies addressing this question remains very limited. Addressing these gaps in knowledge could inform the development of targeted prevention programs and interventions for people with psychotic spectrum disorders.}, }

First, temperature was the dominant driver: each 1&#xb0;C increase reduced respiratory syncytial virus (RSV; RR 0.13, 95% CI 0.08-0.22), influenza virus (IV; RR 0.37, 95% CI 0.23-0.58), human metapneumovirus (HMPV; RR 0.48, 95% CI 0.32-0.73), SARS-CoV-2 (RR 0.52, 95% CI 0.35-0.78), and human coronavirus (HCoV; RR 0.21, 95% CI 0.07-0.61) risks, but increased parainfluenza virus (PIV; RR 2.35, 95% CI 1.46-3.77) and human bocavirus (HBoV; RR 1.86, 95% CI 1.04-3.32) risks. Second, other climate factors showed selective effects: higher humidity decreased IVB risk (RR 0.61, 95% CI 0.40-0.94) but increased enterovirus risk (RR 2.21, 95% CI 1.08-4.51); precipitation decreased IV risk (RR 0.67, 95% CI 0.51-0.89) but increased PIV risk (RR 1.91, 95% CI 1.21-2.99); wind speed amplified IV (RR 1.51, 95% CI 1.01-2.27) and HCoV transmission (RR 5.36, 95% CI 3.43-8.38). Third, climate-zone analyses revealed substantial heterogeneity: in temperate regions, low temperature and humidity increased the risk of most infections (except PIV and HBoV); risks of SARS-CoV-2 and SARS-CoV risks decreased in temperate but increased in continental regions; RSV and HMPV showed greater sensitivity in tropical regions; while in arid regions, MERS-CoV risk increased with temperature but decreased with humidity and wind speed.<br><br>CONCLUSION: This analysis identified climate-sensitive VRIs with temperature as key predictor, pathogen-specific sensitivities, and distinct regional patterns, informing targeted climate-based intervention strategies.}, }

This narrative review, following PRISMA-ScR (Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Narrative Reviews) guidelines, collected evidence from 2020 to 2025 to examine the connection between denture use, systemic comorbidities, and fungal complications in elderly individuals after COVID-19. A total of 21 of 104 studies were included, covering case-control, cross-sectional, cohort, and retrospective studies from India, Europe, the Middle East, and North America. Several studies have reported higher rates of oral fungal colonization among denture wearers,with Candida albicans being the most frequently isolated species, followed by resistant strains such as Candida auris. However, these observations are primarily derived from heterogeneous observational studies and should therefore be interpreted as associative rather than causal. COVID-19-related mucormycosis (CAM) was primarily reported as rhino-orbito-cerebral disease, with oral manifestations including palatal necrosis, gingival ulcers, and tooth mobility. Key risk factors identified include diabetes mellitus, corticosteroid therapy, prolonged intensive care unit (ICU) stays, and poor denture hygiene. Mortality related to CAM ranged from 18% to 56%, while candidiasis, though less deadly, significantly affected oral function, nutrition, and overall quality of life. Diagnostic methods included clinical and intraoral examinations, microbiological cultures, imaging techniques, and emerging salivary biomarkers. Treatments included systemic antifungal medications, surgical removal, and prosthesis disinfection, highlighting the important role of prosthodontists in prevention and rehabilitation. Knowledge gaps remain regarding the predictive value of oral lesions for systemic infections, the long-term effects of COVID-19 on the oral microbiome, and the need to standardize denture hygiene protocols. This review emphasizes the importance of integrated dental and medical care in reducing morbidity and mortality among denture-wearing older adults recovering from COVID-19, while recognizing that early oral findings may serve as warning indicators rather than definitive predictors of systemic infection.}, }

While gain-of-function mutations in IFIH1 have been linked with systemic inflammatory diseases, loss-of-function remains less well understood. This systematic review, following Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidance, explored how IFIH1/MDA5 loss-of-function affects susceptibility to virus infections and/or contributes to inflammatory diseases. Sixteen loss-of-function variants affecting IFIH1 were discussed across 33 studies. Loss-of-function variants were consistently associated with increased susceptibility and/or severity of virus infections, including severe acute respiratory syndrome coronavirus (SARS-CoV2) and human immunodeficiency virus (HIV). Several rare biallelic IFIH1 mutations lead to profound immunodeficiency, while heterozygous mutations associate with milder clinical presentations. Likely through dampening IFN responses, several variants protect from the development of inflammatory diseases, including type 1 diabetes and hypothyroidism. However, IFIH1 deficiency is also implicated in the development of inflammatory diseases, including inflammatory bowel disease. Moreover, the presence of inactivating anti-MDA5 antibodies may alter the clinical phenotypes and prognosis of dermatomyositis and infections with SARS-CoV2. Though their exact impact on MDA5 function has not been confirmed experimentally, anti-MDA5 antibodies may result in loss-of-function and impaired host defence against viruses. Loss of IFIH1/MDA5 activity has diverse effects on anti-viral immunity, associated damage and susceptibility to inflammatory disease, but also protection against organ-specific immune-mediated pathology. Findings highlight the importance of IFIH1 in immune regulation and warrant future studies exploring its potential as a diagnostic and therapeutic target.}, }

Key achievements included integrated vector management, community engagement, and strengthened cross-border initiatives. However, interruptions during the COVID-19 pandemic and a resurgence of malaria in 2022, largely associated with imported infections, operational disruptions, and emerging vector threats, highlighted vulnerabilities in elimination-phase systems.

Microglia, neutrophils, oxidative stress mediators such as reactive oxygen species (ROS), lipid peroxidation products (e.g., malondialdehyde), and nitrosative stress markers (e.g., nitrite and nitrate) play important roles in neuroinflammatory mechanisms. Microglial cells acquire a proinflammatory phenotype through interactions with endogenous or exogenous compounds, including cell debris, abnormally modified proteins (including Aβ species and alpha-synuclein), and pathogens (e.g., SARS-CoV-2). They produce many inflammatory mediators and promote the activation of adjacent brain cells and leukocyte infiltration, including polymorphonuclear neutrophils. Accumulation of neutrophils in the central nervous system (CNS) leads to the secretion of more proinflammatory mediators, such as cytokines, proteases, and oxidants, and the formation of neutrophil extracellular traps (NETs). These processes are associated with the pathological activation of microglial cells, cell death, consequent influence on neuronal functions, or even neuronal death, which is a hallmark of CNS disorders. In this review, we address the importance of inflammatory mechanisms and oxidative stress in the CNS associated with Parkinson's disease, Alzheimer's disease, and the neuronal effects observed in coronavirus disease 2019 (COVID-19), as observed by the abnormal activation of central and peripheral immune cells, such as microglia and neutrophils. We also discuss emerging evidence linking SARS-CoV-2 infection to neuroinflammatory mechanisms that could contribute to neurodegenerative complications.}, }

Despite advancements in medical mycology, IPA continues to pose significant diagnostic and therapeutic challenges, contributing to high global morbidity and mortality. Diagnostic accuracy remains limited due to nonspecific clinical manifestations and the suboptimal performance of conventional tools such as bronchoalveolar lavage culture and galactomannan testing. However, recent innovations including polymerase chain reaction-based molecular assays, lateral flow devices, and immuno-positron emission tomography/magnetic resonance imaging offer improved sensitivity, specificity, and speed. Therapeutically, triazoles remain the cornerstone of IPA management, complemented by echinocandins and liposomal amphotericin B in refractory cases. The role of combination therapy and antifungal susceptibility testing is growing in response to rising azole resistance. Additionally, novel antifungal agents and immunotherapeutic approaches are currently under clinical investigation. Effective management of IPA requires a timely, multidisciplinary approach that combines advanced diagnostics with personalized antifungal strategies. Continued research is essential to standardize molecular techniques, refine immunotherapy, and expand access to next-generation antifungals to reduce the global burden of this life-threatening infection. This review aims to synthesize current evidence on the diagnosis and treatment of IPA, critically evaluate the strengths and limitations of existing diagnostic and therapeutic approaches, and explore emerging strategies to enhance clinical outcomes in the context of rising antifungal resistance.}, }

Added to these are the increased rates of morbidity and mortality from having limited healthcare services available due to a lack of funding, poor disease surveillance systems, and entrenched systemic weaknesses. The purpose of this systematic review was to report the prevalence of infectious diseases in Jordan and Palestine in order to inform the development of targeted public health programs that use both standard and novel approaches to reduce the region's disease burden.<br><br>METHOD: As defined by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, the review included prospective, retrospective, cross-sectional, and case series studies published from January 2021 to February 2024. Non-English studies were excluded due to resource limitations, as were studies published before the COVID-19 pandemic (i.e., before January 2021) to focus on post-COVID-19-pandemic trends. We used diagnostic techniques (screening, laboratory, and confirmatory tests) to test for microorganisms in adults and children from at-risk populations in Jordan and Palestine. Test-negative controls were contrasted with patients who had positive test results. A manual reference screening process was added to a systematic search of PubMed and Scopus. Full-text, English-language publications published after January 2021 were eligible; protocols, reviews, case reports, and articles written in languages other than English were not. The Rayyan platform was used by two reviewers to independently screen studies. Infection type, causative microorganism, symptoms, mortality, risk factors, seasonal fluctuations, and study details (author, year, location, design, and participant characteristics) were among the extracted data. The Hoy 2012 Checklist was used to evaluate the risk of bias. Open Meta (Analyst) was used to analyze the 13 studies that satisfied the inclusion criteria. Study design, risk of bias, heterogeneity, publication bias, indirection, imprecision, effect size, and residual confounding were all considered when grading the quality of the evidence using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach.<br><br>RESULTS: The results revealed that four studies addressed the prevalence of Brucella infection in Jordan and Palestine. The pooled estimate was 42.2% (95% CI: 18.8%-65.6%, I [2]: 99.7%, P: 0.001, n&#x2009;=&#x2009;4 studies, 4,483 patients). In the studies that addressed diarrhea, in 31 of 159 (19.5%) cases, 20 were caused by Entamoeba (12.6%), 10 were caused by Blastocystis (6.3%), and 1 (0.6%) was caused by Cryptosporidium. As some cases had more than one parasite, the certainty of evidence (COE) was assessed as very low. The pooled estimate for viral causative agents of respiratory tract infections was 60% (95% CI: 11.8%-100%), while for bacterial causes, the pooled estimate was 24.4% (95% CI: 0%-68.3%). Respiratory syncytial virus (RSV) was the most common agent, with a pooled estimate of 57.9% (95% CI: 29.8%-85.9%), while influenza had a pooled estimate of 28.4% (95% CI: 5.3%-51.5%). Furthermore, two studies addressed the prevalence of meningitis in pediatric patients. In adult patients, of 192 patients known to have meningitis, a causative agent was identified in only 86 cases, with 83 (49%) classified as aseptic meningitis.<br><br>CONCLUSION: The review addressed the limitations of diagnostic capacity, reporting systems, and population-level data concerning high-burden and emerging pathogens within Jordan and Palestine. Specifically, the growth in the number of cases with respiratory tract infections, protozoal diarrheal diseases, and brucellosis indicates that improvements in surveillance systems and diagnostic processes need to be standardized and implemented throughout Jordan and Palestine to provide accurate and reliable diagnoses. In addition, improving the quality and quantity of the data and incorporating new technologies and other innovative approaches as a complement to existing public health indicators within Jordan and Palestine would be beneficial for better detecting these diseases at the earliest possible time and would provide the opportunity to establish evidence-based disease management strategies within the region.}, }

We discuss the possible mechanisms behind the delayed resurgence, including waning immunity and the persistence of M. pneumoniae reservoirs. There have been contrasting reports on disease severity with notable differences in severity between children and adults, with young adults showing marked vulnerability. The inability of M. pneumoniae diagnostic tests to differentiate between infection and carriage poses a continuing challenge: in daily clinical practice as well as in the interpretation of study results. Furthermore, several studies report safety and utility for tetracyclines and fluoroquinolones as treatment alternatives to macrolide antibiotics.<br><br>SUMMARY: The global resurgence of M. pneumoniae following COVID-19 pandemic restrictions has provided a unique opportunity to study its epidemiology and pathophysiology, which has advanced our understanding of M. pneumoniae infections in children.}, }

Recent data highlights its essential role beyond haemostasis, in the development of venous thrombosis (VT) and endothelial dysfunction influenced by genetic and acquired factors. This review summarizes the biology, synthesis, and activation of FVIII, emphasizing its role in thrombin generation and endothelial dysfunction. FVIII is implicated in inflammatory and thrombotic disorders, such as COVID-19, sepsis, and cancer-associated thrombosis. Although anticoagulant medication indirectly reduces elevated FVIII levels, direct intervention is constrained by the associated bleeding risks. Novel approaches like RNA interference, gene editing, and endothelial-specific modulation might offer compelling opportunities for the regulation of FVIII. This study highlights the potential of FVIII as a diagnostic and therapeutic target in thrombosis by integrating molecular insights with clinical data, hence promoting future precision-based therapies.}, }

These inflammatory diseases include airway inflammation, asthma, bacterial antigens-induced tonsil epithelial inflammation, chronic obstructive pulmonary disease (COPD), cystic fibrosis (CF), COVID-19, acute lung injury, and lung cancer. This review summarizes the relevant molecular mechanisms of inflammatory diseases in the respiratory tract and the progress of natural bioactive components in inflammatory diseases in the respiratory tract. The natural bioactive components have good therapeutic or intervention effects on inflammatory airway diseases in vitro, in vivo, and in clinical trials. The information on inflammatory diseases in the respiratory tract and natural bioactive ingredients in anti-inflammatory diseases were collected from famous literature databases such as Web of Science, PubMed, and Google Scholar, with keywords including bioactive components, inflammatory diseases, respiratory tract, and so forth. The bioactive phytochemicals, such as curcumin, ginsenoside, safranal, melatonin, could improve inflammatory diseases through the regulation of PI3K/Akt, NF-κB, NRF2/HO-1, MAPK, cAMP-PKA, and MEK/ERK Signaling pathways. Further high-quality studies are still needed to firmly establish the clinical efficacy of bioactive ingredients.

PPIs irreversibly inhibit the H+/K+-ATPase enzyme in gastric parietal cells, effectively reducing gastric acid secretion. These drugs are widely prescribed for conditions like gastroesophageal reflux disease (GERD), peptic ulcer disease, eradication of Helicobacter pylori and as a prevention against bleeding from gastrointestinal tract. The review article highlights significant drug interactions associated with PPIs. Omeprazole, for instance, can interfere with the metabolism of clopidogrel, reducing its antiplatelet efficacy, which may have clinical implications. The article also discusses other drug interactions, including anticoagulants (e.g., warfarin), selective serotonin reuptake inhibitors (SSRIs), and immunosuppressive and chemotherapeutic drugs, as well as the side effects associated with taking PPIs. Long-term use of PPIs is linked to plenty of adverse effects, such as vitamin B12 and calcium deficiencies, which can lead to bone fractures. An increased risk of infections, including Clostridium difficile and small intestinal bacterial overgrowth (SIBO), is also noted. Cardiovascular risks, such as myocardial infarction and stroke, are observed in some patients on high-dose or prolonged PPI therapy. In rare cases, nephrotoxicity and hepatotoxicity are reported. Additionally, the document examines the potential role of PPIs in exacerbating certain cancers, such as gastric adenocarcinoma, and in influencing the severity of COVID-19 symptoms. PPIs are proven effective in treating GERD and preventing complications from nonsteroidal anti-inflammatory drugs (NSAIDs), particularly in reducing the risk of NSAID-induced ulcers. The document stresses the importance of understanding drug interactions and the need for individualized treatment to minimize adverse effects. Ongoing research into PPIs' long-term safety and efficacy remains essential, particularly given their widespread use in clinical practice.}, }

This review initially examines the primary physiological activities, mechanisms of action, and challenges related to TFs. It subsequently details the formation mechanism of enzyme-catalyzed TFs from catechins. Building upon this groundwork, this review assesses the recent advancements in two in vitro synthesis methods of TFs: enzymatic oxidation and nonenzymatic synthesis. Finally, the challenges that arise during the large-scale industrial implementation of these synthesis techniques are analyzed, and research strategies aimed at mitigating these issues are suggested. The primary goal of this review was to provide insightful perspectives and guidance for prospective research and industrial utilization of TFs.}, }

The clinical picture is dominated by neuropathic pain, often accompanied by autonomic symptoms of variable severity. The underlying causes encompass metabolic conditions like diabetes mellitus, immuno-mediated disorders, infection, exposure to toxins, and gain-of-function variants in the genes encoding the Nav1.7, Nav1.8, and Nav1.9 sodium channel subunits, though the list of associated diseases continues to grow. Recently, increased attention has focused on immune-mediated forms, which led to the identification of potentially treatable subgroups. These discoveries have advanced our understanding of pathophysiological mechanisms.<br><br>RECENT FINDINGS: Recent studies have broadened the spectrum of underlying conditions associated with SFN, including immune-mediated forms and links to SARS-CoV-2 infection and vaccines. Studies on genetic variants linked to unique clinical presentations have also yielded new insights.

New questions were asked about theranostics, working remotely, hypofractionation and the impact of COVID-19 on work practices.<br><br>RESULTS: The census was sent to 591 radiation oncologists with an overall response rate of 52%. Almost half of respondents (n&#x2009;=&#x2009;94/210; 45%) indicated that COVID-19 had no impact on the uptake of hypofractionation. Hypofractionation was most used by respondents in breast and prostate treatment (n&#x2009;=&#x2009;134/200; 67% and n&#x2009;=&#x2009;112/194; 58% respectively). Five respondents (n&#x2009;=&#x2009;5/270; 2%) currently practise in theranostics, with the majority treating thyroid cancers within the public sector. Just under half (n&#x2009;=&#x2009;81/167; 49%) of invited trainees responded. The majority felt that COVID-19 had a negative impact on their training. There has been a decrease in the number of new fellows seeking to complete further fellowships. Employment remains at very high levels for new fellows (>&#x2009;98%).<br><br>CONCLUSION: The impact of COVID-19 on local practices and workloads was not as significant as seen overseas.

Studies using [18F]-FDG positron emission tomography (FDG-PET) have revealed diverse abnormalities in brain glucose metabolism during the post-acute phase of COVID-19. We conducted a systematic review and meta-analysis to assess the spatial distribution and heterogeneity of brain metabolic changes in patients in the post-acute phase of COVID-19 relative to controls. We searched the MEDLINE, EMBASE, and CENTRAL databases in June 2025 for studies reporting FDG-PET data in patients with post-acute COVID-19 who have persistent neurological symptoms. Of the 14 eligible studies (584 scans), 13 reported glucose hypometabolism across frontoparietal regions, with the frontal cortex being the most consistently affected. This finding was confirmed by meta-analysis, which revealed a large and significant effect in the frontal cortex (Hedges' g = 1.34; 95% CI: 0.79-1.88; p < 0.001), despite high heterogeneity (I[2] = 93.6%). The systematic review indicates that brain metabolism generally improves over time, with widely varying recovery timelines, and consistently correlates hypometabolism with neurological symptom burden. These findings underscore the clinical relevance of frontoparietal hypometabolism in post-acute COVID-19 and its association with neurocognitive deficits, highlighting the need for longitudinal, quantitative PET studies to elucidate temporal dynamics and inform therapeutic development.}, }

Important strides have been made in recent years in vaccination, drug prophylaxes and the use of growth-factor support. We detail these changes to the respective recommendations here.Patients with malignant disease are recommended to receive vaccinations against common respiratory pathogens (COVID-19, influenza, pneumococci, and RSV). For both influenza (now trivalent vaccine) and pneumococci (now PCV20), the preferred vaccine has changed. A VZV vaccination using an inactivated virus-subunit is also recommended to prevent reactivations. The profound B-cell depletion caused by CAR-T cell therapy is increasingly being considered in vaccination recommendations.In high-risk situations, antibiotic prophylaxis using fluoroquinolones can be used. However, due to increasing resistance and significant side effects, this approach is being critically evaluated.Posaconazole is recommended as the standard prophylaxis for patients with neutropenia >7 days (<0,5G/L) and hematologic malignancies. Isavuconazole offers an effective alternative for patients who cannot tolerate posaconazole. Interactions between antifungal agents and oncological therapies are becoming increasingly relevant, with particular attention to the CYP-450-enzyme inducing/inhibiting substances. Non-pharmacological measures to prevent fungal infections are now part of the recommendations. These include smoking cessation.Pharmacological prophylaxis for COVID-19 is generally not recommended.The thresholds for primary growth-factor-support have been lowered: G-CSF is generally recommended if the risk of febrile neutropenia is >20%, or, if patient inherent risk factors are present, >10%. A new long-acting, non-PEG-containing G-CSF preparation was approved in 2024.Good collaboration between oncologists and general practitioners is essential to translate these recommendations into clinical practice.}, }

Despite the widespread prevalence of olfactory disorders, the pathophysiological mechanisms of their development, as well as the molecular basis of their association with the underlying disease, remain incompletely understood. The current work formulates a new concept of the origin of olfactory disorders, linking a decrease in the activation of olfactory neurons and their death to the fibrillogenesis of odorant-binding proteins (OBPs), which are the primary participants of olfactory perception. The potential triggers of OBPs' amyloidogenesis in vivo are discussed, such as molecular crowding, components of nasal medications, environmental factors, and cross-seeding with viral and bacterial amyloids. Several ways of impairment of olfactory signaling as a result of fibrillogenesis of OBPs are formulated: complete loss of OBPs functionality following amyloid formation; mechanical blockage of the membranes of sensory neurons and damage to chemoreceptors on their surface, preventing olfactory signaling; cytotoxic effect of OBPs' amyloid on sensory neurons and other cells of the olfactory epithelium. The proposed concept offers a novel perspective on the pathogenesis of olfactory dysfunction, as well as its possible association with amyloidoses, including in neurodegenerations, and infectious diseases. It opens prospects for the development of new therapeutic approaches to the treatment of olfactory disorders.}, }

However, the inherent variability in model performance due to random weight initialization raises questions about the reliability and consistency of these architectures for time series analysis. This study addresses this concern by conducting a comprehensive benchmark evaluation of nine neural network architectures: vanilla RNN, LSTM, GRU, and six hybrid configurations (RNN-LSTM, RNN-GRU, LSTM-RNN, GRU-RNN, LSTM-GRU, and GRU-LSTM). Performance evaluation was conducted using Monte Carlo simulation with 100 iterations across three real-world datasets: sunspot activity, Indonesian COVID-19 cases, and dissolved oxygen concentration measurements. Statistical analysis employed the Friedman test to assess performance differences across architectures. Results showed no statistically significant differences among the nine architectures. Despite the lack of statistical significance, consistent performance patterns emerged favoring LSTM-based hybrid architectures. The LSTM-GRU and LSTM-RNN configurations demonstrated superior performance across multiple evaluation metrics, with LSTM-RNN excelling in sunspot and dissolved oxygen forecasting, while standalone LSTM showed optimal performance for COVID-19 prediction. These findings provide evidence-based guidance for architecture selection in time series forecasting applications, suggesting that while statistical equivalence exists among architectures, LSTM-based hybrids offer practical advantages in terms of consistency and robustness across diverse temporal patterns.}, }

The complex and intricate ecology of bat viromes results largely from species diversity, roosting patterns, social structures, immunological adaptations, and their remarkable longevity, especially compared to other small mammals such as rodents. These traits allow bats to carry pathogenic viruses without visible clinical symptoms over extended periods. This review delves into the virome of bat populations focusing on major families like Coronaviridae, Filoviridae, Paramyxoviridae and the evolutionary processes leading to their diversity, persistence within populations, and spill-over. The human-induced environmental disturbance in the form of deforestation, cultivation, urbanization, and wildlife trade has increased direct or indirect contact among bats, humans, and domestic animals, increasing the chances of spill-over. The study of historical events in the form of SARS, MERS, Nipah, Ebola is used for practical implications. We also discuss the behavioral and seasonal variations among intra-colony transmission, the role of intermediate hosts, and the critical need of having an effective One Health-based surveillance system. The understanding of ecological and evolutionary drives behind bat virome is necessary for anticipating zoonotic spill-over events, which can be used as a foundation for public health strategies. Finally, the necessity of integrating virology, ecology, and global health policy perspective in human health policy-making is also discussed, in the context of bat virome research, to prevent future pandemics.}, }

We conducted a scoping review to comprehensively map and summarise the evidence on both admission avoidance and early-supported discharge up until now.<br><br>DESIGN: A scoping review of randomised controlled trials (RCTs), conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis: extension for Scoping Reviews (PRISMA-ScR) guidelines.<br><br>DATA SOURCES: Ovid MEDLINE, Embase, CINAHL and Web of Science were systematically searched up to July 2024 ELIGIBILITY CRITERIA FOR SELECTING STUDIES: We included English-language RCTs published from 2005 onwards, involving adults (&#x2265;18 years) receiving acute care at home who would otherwise require hospital admission. Eligible studies evaluated admission avoidance or early supported discharge within HaH settings for acutely ill patients. Studies focusing on outpatient care, non-acute conditions or interventions not aligning with the widely accepted HaH definition were excluded. COVID-19-related studies were also excluded to avoid context-specific bias.<br><br>DATA EXTRACTION AND SYNTHESIS: Two reviewers independently extracted data on study characteristics, interventions and outcomes including mortality, length of stay, escalation rates, costs and patient and caregiver satisfaction. Implementation facilitators and barriers were also collected. Discrepancies were resolved by a third reviewer. Results were synthesised descriptively in accordance with PRISMA-ScR guidelines.<br><br>RESULTS: Nine RCTs were identified. The review shows that the HaH model is at least as safe as usual care, with lower or comparable mortality rates. Length of stay varied, with some studies reporting longer stays in the HaH group due to cautious clinical practices. Cost analyses often indicate lower healthcare costs with staffing as the largest expense. Patient and caregiver satisfaction was high, but essential implementation factors were not clearly addressed.<br><br>CONCLUSION: The HaH model represents a promising alternative to acute inpatient care for suitable patients. Future research should focus on conducting larger RCTs, expanding the range of conditions suitable for HaH. Despite favourable clinical outcomes, substantial implementation barriers remain underexplored in current RCTs. This underscores the need to identify strategies for successful implementation, including the integration of technological advancements and qualitative insights into patient and caregiver experiences.}, }

A literature search of MEDLINE, Embase, Web of Science, and Scopus was conducted to identify studies published until March 2024 focusing on telemedicine services for LGBTQIA + individuals. Data extraction captured study characteristics, telemedicine applications, and patient and provider satisfaction, and was synthesized to map current knowledge and identify gaps. Thirty-eight studies, comprising observational studies and one randomized controlled trial, were included, encompassing 21,774 participants. Telemedicine facilitated access to gender-affirming care, reduced mental health disparities, and supported HIV and STI testing, with high satisfaction reported among patients and providers. It was particularly effective in reducing appointment no-show rates, enabling remote initiation of pre-exposure prophylaxis for HIV, and offering mental health support through virtual counseling. The studies also highlighted increased telemedicine adoption for follow-up visits and medication management. However, challenges like digital privacy concerns, technological accessibility, and cultural competence were identified. Telemedicine holds significant potential to improve healthcare access and outcomes for LGBTQIA + populations, particularly in rural and underserved areas. Future efforts should focus on enhancing provider training, ensuring digital equity, and developing culturally competent telehealth models to fully realize these benefits. The findings can inform the design of inclusive telemedicine policies and services tailored to the needs of LGBTQIA + individuals.}, }

The unusual severity of liver injury and clustering of cases in immunocompetent children have prompted investigations into whether HAdV is truly hepatotropic or merely an incidental finding. Several hypotheses have been proposed, including adenovirus infection, prior severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection or adeno-associated virus-2 (AAV2) with a helper virus (HAdV) co-infection.

The review further discusses how the emergence of coronavirus disease (COVID-19) influenced CRBSI rates and prevention strategies in the post-COVID-19 era. Methods: A targeted literature search was conducted of Embase, Ovid MEDLINE, and EBM Reviews. Where applicable, supplemental hand searches were performed to identify evidence for gaps in the targeted search results. The authors reviewed each study and selected those for inclusion based on the population, intervention, comparison, outcomes, and study design (PICOS) criteria. Relevant studies were assessed for inclusion in the present review. Results: Both "active" methods (scrubbing, flushing, and locking) and "passive" methods (disinfection caps) have consistently been shown to reduce CRBSI risk when assessed individually. These practices have markedly improved CRBSI rates over the past two decades, although there are ongoing gaps in catheter care and adherence to best practices. COVID-19 reversed the trend towards improving CRBSI rates, and persistent challenges for nurse staffing and training have resulted in a failure to return to pre-COVID-19 CRBSI rates in the current post-COVID-19 era. These challenges are further compounded by limited rigorous comparative evidence assessing the relative efficacy of individual CRBSI prevention methods. Conclusions: Improving adherence to hub disinfection, along with catheter care and maintenance protocols, is essential for the prevention of CRIs. Further, innovative approaches for simplifying protocols and "forcing function" may increase compliance with CRBSI prevention strategies. In our practice, we routinely use disinfection caps in addition to standard scrubbing and flushing, alongside increased training and monitoring procedures. Additional studies are needed to assess which individual or combination prevention strategies are most efficacious and feasible in the post-COVID-19 era.}, }

Several infectious diseases caused by pathogens such as SARS-CoV-2, Ebola, Zika, Dengue, Marburg viruses, Mycobacterium tuberculosis, etc. have caused a devastating impact on lives and livelihoods around the world. To counter these diseases, medical experts rely on conventional techniques, which include microscopy and serological testing. However, these conventional methods are hindered by several trade-offs, including high cost, longer processing times, low sensitivity, and a likelihood of false positive results. Biomedical sensors have gained momentum in clinical diagnostics due to their low cost, portability, and sensitivity, among other advantages. To improve their performance, scientists have incorporated nanomaterials. Other techniques used to enhance the performance of nanobiosensors include multiplex testing, point-of-care testing (POCT), and smart sensing.<br><br>METHODOLOGY: Thus, in this review, we present a comprehensive overview of the state-of-the-art nanobiosensors for detecting infectious diseases.

The review presents a comprehensive overview of the technical principles underlying digital image acquisition, addressing factors such as lighting conditions, device variability, color spaces, and image formats, and examines their impact on analytical accuracy and reproducibility. A wide array of laboratory experiments is discussed, spanning analytical and physical chemistry, with applications in colorimetric assays, fluorescence, flame emission, titrations, and chemical equilibrium studies. Digital imaging has been successfully applied to quantify various analytes, including food dyes, proteins, pharmaceuticals, cations, and anions. The review also emphasizes the pedagogical benefits of these approaches, particularly in remote and resource-limited settings where students can perform meaningful scientific investigations using their own devices. The integration of digital imaging into laboratory instruction promotes student engagement, autonomy, and inquiry-based learning. Its widespread adoption was further accelerated by the COVID-19 pandemic, which demonstrated the feasibility of at-home experimentation. As imaging technologies continue to advance, their potential to democratize access to scientific tools and enhance chemical education is expected to expand, fostering a more inclusive, innovative, and effective approach to laboratory science.}, }

This nucleoside exerts its effects via four G protein-coupled receptors-A1, A2A, A2B, and A3-each displaying distinct roles during renal injury. The A1 receptor primarily protects renal tissue under ischemic conditions by reducing metabolic demand, while the A2A receptor promotes anti-inflammatory and vasodilatory effects, improving renal perfusion and attenuating leukocyte infiltration. The A2B receptor, upregulated under hypoxic or injury conditions, is involved in anti-inflammatory actions and vascular integrity, especially in renal tubular and endothelial cells. Conversely, activation of the A3 receptor is generally linked to adverse outcomes, including increased apoptosis and greater tissue damage. Therapeutic strategies targeting adenosine receptors are being actively explored: selective A1 and A2A agonists show potential for promoting renal recovery, while A3 antagonists helped counteract the harmful effects of A3 activation. The review also discusses advances from recent studies (2022-2024), including insights on COVID-19-associated AKI and the nuanced roles of A1 and A3 receptors in different pathological contexts. Additionally, the therapeutic promise of inhibiting adenosine-degrading enzymes, such as ADA and adenosine kinase (ADK), is highlighted. Novel mechanistic insights and recent literature are integrated, providing a comprehensive overview that expands upon previous reviews.

In 2021, it was proposed that the cytokine storm observed in patients with severe COVID-19 may be initiated by sensing of cytoplasmic DNA released by micronuclei, which arises as a consequence of virus-induced genomic instability. Subsequent studies have described the presence of micronuclei and other genotoxic and cytotoxic markers in COVID-19 patients. However, the association between the development of a cytokine storm and cytoplasmic DNA sensing remains to be fully elucidated. In this review, we summarize current evidence on the dysregulated cytokine production in response to the detection of genetic material during SARS-CoV-2 infection. We focused mainly on the dysregulated production of cytokines induced by the activation of cytosolic DNA sensing pathways that promote inflammation. We emphasize the need to analyze the contribution of these signaling complexes to COVID-19 pathophysiology. DNA sensing amplifies the inflammatory response and plays a crucial role in the pathogenesis of severe disease manifestations observed in infected patients. Understanding this complex interplay can provide insights into potential therapeutic targets aimed at mitigating the hyper-inflammatory responses seen in severe COVID-19 cases.}, }

With the COVID-19 pandemic casting new light on these inequities, we conducted a scoping review to determine how much has been written on ethical issues in rural health research and which ethical issues are most prevalent. Four overarching ethical themes emerged through the search: resource inequity, underrepresentation, the benefits of community-based research, and challenges related to participant autonomy. Additionally, the search revealed a dearth of articles on ethical issues in rural health research, particularly in the United States. Thus, we propose four recommendations to revitalize and guide ethics discussions of research in rural communities, including growing the literature on ethical issues in rural U.S. communities, encouraging collaboration between rural health and bioethics researchers, improving recognition of rural heterogeneity, and addressing new issues in light of COVID-19. Acting on these recommendations would expand and support rural research efforts and ultimately help ameliorate rural-urban health inequities.}, }

Analogous to an FBI agent, host cells have numerous molecular "detectives" that recognize viral nucleic acids (NAs). These include RIG-I, MDA5, LGP2, TLR3, TLR7, TLR8, DHX36, DICER1, PKR, OAS1, ZAP, and NLRP1/6 for viral RNA, as well as cGAS, TLR9, AIM2, IFI16, IFIX, Ku70, MRE11, RNA polymerase III, hnRNPA2B1, LRRFIP1, DAI, DHX9 and DDX41 for viral DNA.

The health implications for this generation are especially concerning, as childhood-onset obesity has more severe health consequences than weight gain that begins in adulthood, including increased risk of type 2 diabetes and diabetes-related complications. The complexity of obesity treatment has been challenging, including remarkable heterogeneity in obesity phenotypes and treatment responses among both adults and children. Many in the field have therefore highlighted a need for precision medicine approaches in obesity treatment across age-groups. This includes a need for precision risk stratification to better target treatment intensity, which will require a better understanding of the earliest stages of metabolic syndrome pathophysiology. The health, function, and distribution of adipose tissue have been established as important determinants of metabolic health in both childhood- and adult-onset obesity, making adipose tissue a promising target for understanding phenotypic heterogeneity in obesity.

Parameters of adipose tissue dysfunction are better predictors of metabolic syndrome than body size, and therefore adipose tissue represents a prime candidate for research approaches in understanding the pathophysiology of insulin resistance and in identifying biomarkers of future prognosis. Expanded developmental research on pediatric adipose tissue in both mice and humans is needed to understand the pathophysiology of childhood-onset obesity and to develop precision treatment approaches.}, }

Toxin-producing bacteria, such as Staphylococcus aureus and Pseudomonas aeruginosa, pose severe risks by producing virulence factors that impair immune function, delay wound healing and exacerbate systemic inflammation. These challenges are amplified in the presence of SARS-CoV-2, as the viral-induced immune dysregulation and cytokine storms worsen clinical outcomes, leading to higher rates of morbidity and mortality. This review explores the interplay between viral and bacterial infections in burn patients during the COVID-19 pandemic, focusing on the role of bacterial toxins, including superantigens from S. aureus and exotoxins from P. aeruginosa in driving hyperinflammatory responses. These synergistic effects complicate treatment by increasing the likelihood of systemic complications, prolonged hospital stays and MDR infections. To address these challenges, we discuss innovative therapeutic strategies, including endotoxin adsorption therapy to reduce systemic inflammation, immunomodulatory treatments to control cytokine storms and bacteriophage therapy for targeting MDR pathogens. Advanced wound care techniques and rapid diagnostic tools, such as CRISPR-based molecular assays, are highlighted as essential for timely and effective intervention. This review underscores the urgent need for integrated approaches that combine targeted diagnostics, advanced therapeutics and robust infection control measures. These insights aim to improve outcomes for burn patients co-infected with bacterial pathogens and SARS-CoV-2, offering valuable guidance for future pandemic preparedness and burn care protocols.}, }

Using PubMed and Google Scholar, peer-reviewed articles and documents were analyzed to assess sources, impacts, and policy effectiveness. Microplastics contaminate rivers, soil, air, fertilizers, and food products. The dominant polymers, including polyethylene, polypropylene, polystyrene, polyethylene terephthalate, and polyamide, originate from fishing nets, industrial discharge, and urban waste, threatening ecosystems and food chains. Plastic pollution is exacerbated by transboundary river systems, excessive plastic production, use of single-use plastics, and ineffective waste management. The Meghna, Karnaphuli, and Rupsha Rivers transport 1 million metric tons of mismanaged waste annually to coastal areas. The plastics industry, employing 1.2 million people across 5,000 manufacturers, has increased per capita plastic consumption from 3 kg in 2005 to 9 kg in 2020, worsening waste accumulation. The COVID-19 pandemic accelerated the crisis, with polythene bag usage increasing to 21 billion, generating 78,433 tons of waste. Plastic pollution costs USD 39 million annually, affecting tourism, fisheries, and municipal budgets, and microplastic contamination threatens seafood exports. Clean-up costs consume 30% of Bangladesh's environmental budget. Using an agent-based system dynamics model, simulations predict that per capita plastic waste will rise to 11.6 kg by 2040, with landfill accumulation reaching 70,000 tons and riverine discharge increasing from 512 to 834 tons, raising the plastic waste footprint index (PWFI) to 24. Policy 2, which implements 69% conversion, 80% source separation, and 50% riverine discharge reduction, proves most effective, lowering PWFI to 1.07 and ensuring sustainable waste management. However, an integrated approach combining research, policy enforcement, technological innovation, and global collaboration is crucial. Strengthening the waste management framework, regulatory enforcement, and sustainable economic strategies will enable Bangladesh to mitigate microplastic pollution, advance its circular economy, and contribute to global environmental conservation.}, }

Patient preferences for physician attire varied significantly by clinical context, medical specialty and physician gender. In outpatient and primary care settings, mixed evidence was reported, with some studies suggesting that a combination of casual attire and white coats may foster approachability and communication, while others showed no clear preference. In contrast, in high-acuity settings such as emergency rooms and operating theatres, scrubs were consistently favoured, indicating moderate to strong evidence for the association with professionalism and preparedness. During the COVID-19 pandemic, patients expressed stronger preferences for scrubs and PPE, emphasising infection prevention and hygiene. Gender-specific findings indicated that male physicians were perceived as more professional when wearing formal attire with white coats, while female physicians in similar attire were often misidentified as nurses or assistants. Specialty-based differences were also observed, with preferences for white coats in dermatology, neurosurgery and ophthalmology, while scrubs were preferred in anaesthesiology and gastroenterology.<br><br>CONCLUSION: This study demonstrates that physician attire consistently and significantly impacts patients' perceptions of professionalism, trust and communication.

The review included all the English-language written peer-reviewed and grey literature reporting on vaccination in Botswana, to broaden coverage in recognition of limited publications on COVID-19 vaccinartion in Botswana. Non-English articles were excluded due to limited translation resources. Due to the heterogeneity of studies, a narrative synthesis approach was used to collect, synthesize, and map the literature.<br><br>RESULTS: As of 31 December 2021, 80.6% of the Botswana national target of 1,390,856 people over 18 years had received at least one dose of a COVID-19 vaccine, while 71.9% were fully vaccinated. Various vaccine distribution channels were utilized, including public facilities and outreaches, to improve access and uptake of vaccines. COVID-19 vaccine acceptance was considered generally high (73.4% amongst adults), and found positively associated with the male gender, those with comorbidities, those with non-restrictive religious beliefs, and those aged 55-64 years who thought the vaccine was safe for use. COVID-19 vaccine delivery relied on existing Expanded Program on Immunization (EPI) structures and therefore experienced to existing EPI challenges including, lack of transport, shortage of human resources, and vaccine stock-outs.<br><br>CONCLUSIONS: Under-performance of immunization programs at the district level, characterized by declining immunization coverage and inadequate outreach services, exacerbates disparities in vaccine access.

Beyond their classical antimicrobial functions, neutrophils contribute to pulmonary injury via the release of reactive oxygen species, proteolytic enzymes, and neutrophil extracellular traps (NETs). To identify targets for treatment, it was found that epigenetic mechanisms, including histone modifications, hypomethylation, hypermethylation, and non-coding RNAs, regulate neutrophil phenotypic plasticity, survival, and inflammatory potential. It has been identified that neutrophils in ARDS patients exhibit abnormal methylation patterns and are associated with altered gene expression and prolonged neutrophil activation, thereby contributing to sustained inflammation. Histone citrullination, particularly via PAD4, facilitates NETosis, while histone acetylation status modulates chromatin accessibility and inflammatory gene expression. MicroRNAs have also been shown to regulate neutrophil activity, with miR-223 and miR-146a potentially being biomarkers and therapeutic targets. Neutrophil heterogeneity, as evidenced by distinct subsets such as low-density neutrophils (LDNs), varies across ARDS etiologies, including COVID-19. Single-cell RNA sequencing analyses, including the use of trajectory analysis, have revealed transcriptionally distinct neutrophil clusters with differential activation states. These studies support the use of epigenetic inhibitors, including PAD4, HDAC, and DNMT modulators, in therapeutic intervention. While the field has been enlightened with new findings, challenges in translational application remain an issue due to species differences, lack of stratification tools, and heterogeneity in ARDS presentation. This review describes how targeting neutrophil epigenetic regulators could help regulate hyperinflammation, making epigenetic modulation a promising area for precision therapeutics in ARDS.}, }

Paradoxically, the same initiating pathophysiology may underpin the systemic findings in COVID-19 infection, namely the multiorgan SARS-CoV-2 infection-induced vascular pathologies and brain-body-wide systemic pro-inflammatory signaling, depending on the concentration and exposure to infecting SARS-CoV-2 viruses. This common initiating microdamage is suggested to be the primary damage or the acquired channelopathy of the Piezo2 ion channel, leading to a principal gateway to pathophysiology. This Piezo2 channelopathy-induced neural switch could not only explain the initiation of disrupted cell-cell interactions, metabolic failure, microglial dysfunction, mitochondrial injury, glutamatergic synapse loss, inflammation and neurological states with the central involvement of the hippocampus and the medulla, but also the initiating pathophysiology without SARS-CoV-2 viral intracellular entry into neurons as well. Therefore, the impairment of the proposed Piezo2-induced quantum mechanical free-energy-stimulated ultrafast proton-coupled tunneling seems to be the principal and critical underlying COVID-19 infection-induced primary damage along the brain axes, depending on the loci of SARS-CoV-2 viral infection and intracellular entry. Moreover, this initiating Piezo2 channelopathy may also explain resultant autonomic dysregulation involving the medulla, hippocampus and heart rate regulation, not to mention sleep disturbance with altered rapid eye movement sleep and cognitive deficit in the short term, and even as a consequence of long COVID. The current opinion piece aims to promote future angles of science and research in order to further elucidate the not entirely known initiating pathophysiology of SARS-CoV-2 infection.}, }

Session 3 focussed on the atypical lymphoid proliferations associated with therapeutic interventions. Forty-four cases were submitted representing a broad spectrum of lymphoproliferative disorders (LPDs) encountered in the settings of immunosuppressive and immunomodulatory therapies, various interventions for solid tumor treatment, drug reaction with eosinophilia and systemic symptoms (DRESS), CAR T-cell therapy for B-cell lymphomas, Bruton tyrosine kinase inhibitors (BTKI) for SLL/CLL treatment, ABL-kinase inhibitor dasatinib, and COVID-19 vaccination. The cases of this session highlighted the importance of having sufficient clinical information including drug history and distribution of disease in order to achieve reliable diagnosis. Among LPDs associated with immunosuppressive and immunomodulatory therapies, the most challenging were T- and NK-derived infiltrates as they ranged from non-clonal to clonal. DRESS-associated lymphadenopathy exhibited variable histologic patterns with the most difficult differential diagnosis being with a T-cell lymphoma. LPDs observed after CAR T-cell therapy for B-cell neoplasms exhibited unexpected phenotypes resulting either from lineage switching/transdifferentiation, or from harvested T-cells already harbouring cancer-associated variants. Temporary interruption of BTKI treatment for CLL/SLL due to surgical procedures led to a "Pseudo-Richter transformation" that disappeared after reintroduction of therapy. Dasatinib led to a lymphadenopathy with a peculiar florid follicular hyperplasia that regressed after discontinuation of therapy. The findings of the few thoroughly studied COVID-19 vaccination associated lymphadenopathy cases reflected a disordered immune response.

The idea centres on coining the advantages of both materials while attempting to overcome the limitations inherent to each component, thus improving biocompatibility, drug loading, stability, size uniformity, and controlled release properties. Since their emergence over two decades ago, LPN have attracted growing interest in various therapeutic areas such as cancer, neurological disorders, osteoarthritis, and COVID-19 viral infections. Their structural diversity has expanded from the classical polymeric core-lipid shell to its inverse structure of lipid core-polymeric shell and homogeneous lipid-polymer blends, producing nine types of LPN under these structural classes. Correspondingly, preparation strategies have evolved from two-step methods to integrated one-step method of nanoprecipitation, single-emulsification-solvent evaporation, and double-emulsification-solvent evaporation in the early 2010s. More recently, novel methods such as self-assembly, modified ionic gelation, modified ethanolic injection, film rehydration, and hot-melt emulsification have been introduced, with hot-melt emulsification showing particular promise for scalability. In this context, the present review proactively introduces an updated structural classification and proposes a revision of existing formulation strategies by expanding the one-step and two-step framework to incorporate emerging methods tailored for dermatological applications. While LPN are often portrayed as a better version of lipid and polymeric-based nanoparticles, their practical applicability in dermatological treatments remains an open question. Therefore, this review evaluates LPN's clinical and translational potential in dermatology applications such as, wounds, skin infections, dermatitis, psoriasis, skin cancer, pain management, and cosmetic applications.}, }

Long COVID in adults is frequently characterized by symptoms of fatigue and breathlessness but brain-fog, joint and muscle pain have been reported much more commonly in adult follow-up than CYP. The most common persisting symptoms experienced by CYP after COVID-19 infection in initial studies, often with less than a year of follow-up, were fatigue, headache, shortness of breath and persisting loss of smell and taste. With longer follow-up, up to 2&#x200a;years, the commonest symptoms still include not only fatigue, headache and shortness of breath but also sleep difficulties, whereas loss of smell and taste persisted only in a minority. However, many symptoms were almost as common in test-negative controls, raising questions about the causal role of SARS-CoV-2 virus. Predictors of long COVID, as defined, were female sex, history of asthma, allergy problems, learning difficulties at school and family history of ongoing COVID-19 problems.<br><br>SUMMARY: The implications of the findings for clinical practice and research are that long COVID is not the same in CYP as adults; both their physical and mental health should be studied; and intervention trials are needed.}, }

Lessons from low- and middle-income countries (LMICs) shaped healthcare practices in a high-income setting. We describe how the FIGO Postpartum Intrauterine Device Initiative, implemented across six LMICs, informed the development of a postpartum contraception program in a UK-based NHS trust. Despite the well-documented benefits of postpartum family planning (PPFP), implementing dedicated PPFP services in the UK has been challenging due to fragmented healthcare funding and cross service integration barriers. The COVID-19 pandemic created an urgent need for adaptation, providing a unique opportunity to rapidly establish a comprehensive local PPFP service. We outline how strategies from LMICs - including task-sharing, provider training, and policy advocacy - were directly applied to overcome these barriers and drive successful implementation.

ILD is an umbrella term, with idiopathic pulmonary fibrosis (IPF) being a prime focus because of its progressive and severe form. Out of 300 underlying etiologies, ILD is one of the major reasons for global morbidity and mortality. This review offers a comprehensive overview of six main categories of ILD covering autoimmune, idiopathic interstitial pneumonia, hypersensitivity pneumonitis, drug-induced, infection-related, and unclassified ILD that underscore the complexity of diagnosis and treatment challenges. This review also provides an evidence-based overview of recent advancements in the diagnosis and management of ILD, with precision pharmacotherapy, multidisciplinary care, and emerging therapeutic strategies. From clinical trial data, it also recommends the disease-specific use of pharmacological agents-such as pirfenidone and nintedanib for IPF, and mycophenolate mofetil for connective tissue disease-associated ILD. The manuscript also emphasizes the evolving role of non-pharmacological interventions, including the 6-minute walk test and pulmonary rehabilitation, in enhancing functional capacity and quality of life. To address the current global health concerns, topics of post-COVID-19 ILD and immune checkpoint inhibitor-associated lung disease are integrated. Additionally, future directions are explored, including the role of lung transplantation and novel antifibrotic therapies like anti-Transforming Growth Factor (TGF)-β antibody cocktails. Together, these insights aim to refine diagnostic precision, personalize treatment, and improve clinical outcomes across the heterogeneous ILD spectrum.}, }

MicroRNAs (miRNAs)-small non-coding RNAs involved in gene regulation-play a pivotal role in this process by modulating immune responses, inflammation, and cellular stress. Altered miRNA expression patterns during and after infection contribute to the pathogenesis of Long COVID. While conventional miRNA detection techniques have been valuable, they face limitations in sensitivity, throughput, and detecting RNA modifications. This review highlights Oxford Nanopore Sequencing (ONS) as a promising alternative, offering real-time, long-read, amplification-free RNA sequencing that preserves native modifications. ONS enables direct sequencing of full-length miRNAs and their precursors, providing novel insights into miRNA processing and regulatory roles.

However, COVID-19 pandemic has worsened the disparities in NCDs care and services in Sub-Saharan Africa (SSA). To date, there is limited synthesized evidence on the impact of COVID-19 on NCDs care and service delivery in this region. Therefore, this review aims to examine the impact of the COVID-19 pandemic on NCDs care and service in SSA.<br><br>METHOD: A systematic search was conducted on various databases and grey literature sources, including PubMed, CINAHL, Web of Science, Embase, Scopus, Google Scholar, and the World Health Organization database. Studies evaluating the impacts of COVID-19 on the management and provision of major NCDs care in SSA were included. Data extraction and review were performed using the JBI SUMARI and PRISMA 2020 checklist, and a narrative synthesis approach was used due to the high heterogeneity of the included studies.

Ultimately, 18 studies (13 quantitative and 5 qualitative) were included. The review identified significant disruptions in delivery of care for NCD care across SSA during the pandemic. It include substantial reduction in outpatient attendance, delayed or cancelled diagnostic service and compromised disease management. These disruptions were influenced by healthcare system overloads, patient fears of contracting COVID-19, and public health measures limiting access to routine care. The studies emphasize an urgent need for adaptive strategies to maintain continuity of care for individuals with NCD during health crises.<br><br>CONCLUSION: The provision of healthcare services for NCDs experienced substantial disruptions during the COVID-19 pandemic, leading to a shift towards managing emergency care. Individuals with NCDs have encountered increased risks of morbidity and mortality due to the delayed access to essential care amidst the pandemic. Emergent solutions like digital health technologies have shown potential in enhancing NCD care access during such crises. Moving forward, it is critical that countries prioritize NCD care and integrate robust systems to ensure the continuous provision of essential services, regardless of the COVID-19 pandemic and other healthcare emergencies.}, }

This life-threatening syndrome results from alveolar-capillary membrane injury, causing refractory hypoxemia and respiratory failure. Early detection and management are critical to treat the underlying cause, provide protective lung ventilation, and, eventually, improve patient outcomes. The 2012 Berlin definition standardized ARDS diagnosis but excluded patients on non-invasive ventilation (NIV) or high-flow nasal cannula (HFNC) modalities, which are increasingly used, especially after the COVID-19 pandemic. By excluding these patients, diagnostic delays can occur, risking the progression of lung injury despite ongoing support. Indeed, sustained, vigorous respiratory efforts under non-invasive modalities carry significant potential for patient self-inflicted lung injury (P-SILI), underscoring the need to broaden diagnostic criteria to encompass these increasingly common therapies. Recent proposals expand ARDS criteria to include NIV and HFNCs, lung ultrasound, and the SpO2/FiO2 ratio adaptations designed to improve diagnosis in resource-limited settings lacking arterial blood gases or advanced imaging. However, broader criteria risk overdiagnosis and create challenges in distinguishing ARDS from other causes of acute hypoxemic failure. Furthermore, inter-observer variability in imaging interpretation and inconsistencies in oxygenation assessment, particularly when relying on non-invasive measurements, may compromise diagnostic reliability. To overcome these limitations, a more nuanced diagnostic framework is needed-one that incorporates individualized therapeutic strategies, emphasizes lung-protective ventilation, and integrates advanced physiological or biomarker-based indicators like IL-6, IL-8, and IFN-γ, which are associated with worse outcomes. Such an approach has the potential to improve patient stratification, enable more targeted interventions, and ultimately support the design and conduct of more effective interventional studies.}, }

This scoping review aims to (1) provide a comprehensive overview of pharmacy technicians' involvement in immunization services across various healthcare settings and countries, and (2) conduct a comparative analysis of training curricula for pharmacy technicians on immunization. Methods: A scoping review was conducted following the Arksey and O'Malley framework. A comprehensive search of the PubMed and Scopus databases was performed using keywords and MeSH terms such as "pharmacy technician(s)", "immunization", "vaccination", "role", and "involvement". Studies included assessed pharmacy technicians' roles in vaccine administration, training, and public health outcomes. Descriptive and thematic analyses were used to synthesize the findings. In addition, a supplementary analysis of immunization training curricula was conducted, reviewing programs from different countries to identify similarities, differences, and gaps in course structure, content, and delivery formats. Lastly, a comprehensive toolkit was developed, offering guidelines intended to facilitate the implementation of immunization training programs. Results: A total of 35 articles met the inclusion criteria, primarily from the United States of America (n = 30), Canada (n = 2), Ethiopia (n = 1), Denmark (n = 1) and United Kingdom (n = 1). The findings indicate that pharmacy technicians contribute significantly to vaccine administration, patient education, and workflow optimization, particularly in community pharmacies. The COVID-19 pandemic accelerated their involvement in immunization programs. Key challenges include regulatory barriers, a lack of standardized training, and resistance from other healthcare professionals. Facilitators include legislative support (e.g., the PREP Act), structured training programs, and collaborative pharmacist-technician models. Conclusions: Pharmacy technicians can play a vital role in expanding immunization services, improving vaccine uptake, and reducing pharmacist workload. Addressing regulatory inconsistencies, enhancing training, and fostering interprofessional collaboration are crucial for their effective integration of immunization programs. Since immunization by pharmacy technicians is not yet allowed in many EU countries, this review will provide a foundational basis to address their potential to support the healthcare workforce and improve access to immunization services.}, }

Increasing evidence implicates viral infections as significant environmental contributors, particularly during sensitive neurodevelopmental periods. This review synthesises current findings on the viral hypothesis of schizophrenia, encompassing a wide array of neurotropic viruses, including influenza viruses, herpesviruses (HSV-1 and 2, CMV, VZV, EBV, HHV-6 and 8), hepatitis B and C viruses, HIV, HERVs, HTLV, Zika virus, BoDV, coronaviruses (including SARS-CoV-2), and others. These pathogens can contribute to schizophrenia through mechanisms such as direct microinvasion, persistent central nervous system infection, immune-mediated neuroinflammation, molecular mimicry, and the disturbance of the blood-brain barrier. Prenatal exposure to viral infections can trigger maternal immune activation, resulting in cytokine-mediated alterations in the neurological development of the foetus that persist into adulthood. Genetic studies highlight the role of immune-related loci, including major histocompatibility complex polymorphisms, in modulating susceptibility to infection and neurodevelopmental outcomes. Clinical data also support the "mild encephalitis" hypothesis, suggesting that a subset of schizophrenia cases involve low-grade chronic neuroinflammation. Although antipsychotics have some immunomodulatory effects, adjunctive anti-inflammatory therapies show promise, particularly in treatment-resistant cases. Despite compelling associations, pathogen-specific links remain inconsistent, emphasising the need for longitudinal studies and integrative approaches such as viromics to unravel causal relationships. This review supports a "multi-hit" model in which viral infections interfere with hereditary and immunological susceptibilities, enhancing schizophrenia risk. Elucidating these virus-immune-brain interactions may facilitate the discovery of biomarkers, targeted prevention, and novel therapeutic strategies for schizophrenia.}, }

COVID-19, caused by SARS-CoV-2, shares several systemic immunohematologic disturbances with IPF, including cytokine storms, endothelial injury, and prothrombotic states. Unlike general comparisons of viral infections and chronic lung disease, this review offers a focused analysis of the shared hematologic and immunologic mechanisms between COVID-19 and IPF. Our aim is to better understand how SARS-CoV-2 infection may worsen disease progression in IPF and identify converging pathophysiological pathways that may inform clinical management. We conducted a narrative synthesis of the peer-reviewed literature from PubMed, Scopus, and Web of Science, focusing on clinical, experimental, and pathological studies addressing immune and coagulation abnormalities in both COVID-19 and IPF. Both diseases exhibit significant overlap in inflammatory and fibrotic signaling, particularly via the TGF-β, IL-6, and TNF-α pathways. COVID-19 amplifies coagulation disturbances and endothelial dysfunction already present in IPF, promoting microvascular thrombosis and acute exacerbations. Myeloid cell overactivation, impaired lymphocyte responses, and fibroblast proliferation are central to this shared pathophysiology. These synergistic mechanisms may accelerate fibrosis and increase mortality risk in IPF patients infected with SARS-CoV-2.

This narrative review aimed to synthesize global epidemiological trends of syphilis from 2015 to 2025, with a focus on surveillance gaps, regional disparities, and structural determinants. Methods: A broad narrative approach was used to collect and analyze epidemiological data from 2015 to 2025. The literature was retrieved from databases (PubMed, Scopus) and official reports from the WHO, CDC, and ECDC. Included materials span observational studies, surveillance reports, and modeling data relevant to global trends and public health responses. Results: Globally, syphilis incidence has increased, with notable surges in North America, Europe, and Asia. MSM remain disproportionately affected, while congenital syphilis is resurging even in high-income countries. Low- and middle-income countries report persistent burdens, especially among women of reproductive age, often exacerbated by limited screening and surveillance infrastructure. The COVID-19 pandemic disrupted syphilis-related services and further exacerbated underreporting, hindering timely detection and response efforts. Surveillance systems vary widely in their completeness and quality, which significantly hinders global data comparability and coordinated public health responses. Conclusions: Despite its curability, syphilis continues to spread due to fragmented prevention strategies, inequities in access to care, and insufficient surveillance. Strengthening diagnostic access, integrating prevention efforts into broader health systems, and addressing social determinants are essential. Improved surveillance, equitable access, and innovation-including diagnostics and potential vaccine research-are critical to controlling the global syphilis epidemic.}, }

At present, a gap exists in understanding the relationship between excessive trading behavior and problem gambling, especially during the COVID-19 period. This narrative review analyzed (1) the changes in trading and gambling activity during the COVID-19 pandemic, (2) whether the pattern of trading activity resembles problem gambling, and (3) whether excessive trading and problem gambling share similar consequences.<br><br>METHODS: We searched databases such as Medline, PsychINFO, Scopus, and Google Scholar using relevant keywords, and included 60 reports for narrative synthesis.<br><br>RESULTS: During the COVID-19 pandemic, there were major changes to trading behavior, possibly due to market sentiments and psychology, personal financial needs, social media influence, and the behavior of other investors. The progression of the pandemic led to an increase in brokerage account openings and an increase in trading activities among existing investors, likely due to the development of digital trading platforms that enhanced accessibility for technology-adept investors. There was also a shift from gambling at physical destinations to online gambling, with an increase in frequency and spending among individuals who continued gambling. Feelings of boredom, stress, and the need for relaxation may motivate people to engage in gambling.<br><br>CONCLUSION: Individuals who engaged in excessive trading and problem gambling shared similar traits and may thus face similar psychiatric consequences. The findings indicate that we can apply the diagnostic criteria for pathological gambling and gambling disorders to excessive trading, given that many of these individuals meet the criteria for an addictive disorder.}, }

Unlike traditional cell therapies that rely on engraftment, MSCs primarily function through paracrine signaling-secreting bioactive molecules like vascular endothelial growth factor (VEGF), transforming growth factor-beta (TGF-β), and exosomes. These factors contribute to tissue repair, promote angiogenesis, and modulate immune responses in damaged or inflamed tissues. Recent studies have identified mitochondrial transfer as a novel therapeutic mechanism, where MSCs donate mitochondria to injured cells, restoring their bioenergetic function. This has expanded the therapeutic potential of MSCs to include conditions such as acute respiratory distress syndrome (ARDS) and myocardial ischemia. Clinically, MSCs have shown efficacy in diseases like graft-versus-host disease (GVHD), Crohn's disease, and COVID-19. Trials such as REMODEL and REMEDY have demonstrated improved clinical outcomes, further validating MSC-based interventions. However, several challenges remain, including variability in cell potency, poor engraftment, and inconsistent results across clinical trials. Advances in genetic engineering such as CRISPR-modified MSCs and biomaterial scaffolds are being developed to enhance therapeutic efficacy and cell survival. Additionally, AI-driven platforms are being utilized to personalize MSC therapy and optimize cell selection. Innovative approaches like 3D bioprinting and scalable manufacturing are paving the way for more consistent and precise therapies. Moving forward, the integration of mechanistic insights with robust quality control and regulatory frameworks essential to translating MSC therapies from bench to bedside and ensuring their reliable application in clinical practice.}, }

PASC has highly variable clinical presentations, and likely includes multiple molecular subtypes, but it remains poorly understood from a molecular and mechanistic standpoint. This hampers the development of rationally targeted therapeutic strategies. The NIH-sponsored "Researching COVID to Enhance Recovery" (RECOVER) initiative includes several retrospective/prospective observational cohort studies enrolling adult, pregnant adult and pediatric patients respectively. RECOVER formed an "OMICS" multidisciplinary task force, including clinicians, pathologists, laboratory scientists and data scientists, charged with developing recommendations to apply cutting-edge system biology technologies to achieve the goals of RECOVER. The task force met biweekly over 14 months, to evaluate published evidence, examine the possible contribution of each "omics" technique to the study of PASC and develop study design recommendations. The OMICS task force recommended an integrated, longitudinal, simultaneous systems biology study of participant biospecimens on the entire RECOVER cohorts through centralized laboratories, as opposed to multiple smaller studies using one or few analytical techniques. The resulting multi-dimensional molecular dataset should be correlated with the deep clinical phenotyping performed through RECOVER, as well as with information on demographics, comorbidities, social determinants of health, the exposome and lifestyle factors that may contribute to the clinical presentations of PASC. This approach will minimize lab-to-lab technical variability, maximize sample size for class discovery, and enable the incorporation of as many relevant variables as possible into statistical models. Many of our recommendations have already been considered by the NIH through the peer-review process, resulting in the creation of a systems biology panel that is currently designing the studies we proposed. This system biology strategy, coupled with modern data science approaches, will dramatically improve our prospects for accurate disease subtype identification, biomarker discovery and therapeutic target identification for precision treatment. The resulting dataset should be made available to the scientific community for secondary analyses. Analogous system biology approaches should be built into the study designs of large observational studies whenever possible.}, }

Therefore, this review systematically evaluates the effectiveness of telemedicine interventions in educating parents or caregivers after pediatric surgery, with respect to caregiver knowledge and self-efficacy in postoperative care, caregiver satisfaction, and postoperative clinical outcomes.<br><br>METHODS: Following the PRISMA guidelines, we searched three databases, PubMed, Scopus, and LILACS, for articles published between 2013 and 2023 that involved patients aged 0-18&#x202f;years who underwent surgery and caregivers who received some form of education through telemedicine. We evaluated the effectiveness of telemedicine for educational purposes by assessing caregiver knowledge, satisfaction, and patient morbidities. Bias was analyzed using the RoB2 and ROBINS-I tools. The certainty of the presented evidence was assessed using the GRADE guidelines. The SWiM guideline was employed to report a structured narrative synthesis from the combined results. The protocol was registered in the International Prospective Register of Systematic Reviews (CRD42024545858).<br><br>RESULTS: Four studies were included from 2,163 records initially registered: two randomized controlled trials (RCTs) and two uncontrolled before-after (UCBAs) studies. In the RCTs, caregiver knowledge was significantly higher in the telemedicine intervention group (p&#x202f;<&#x202f;0.05); in one UCBA, caregiver knowledge increased over time. All studies reported high satisfaction with telemedicine, with the RCTs showing significantly higher satisfaction levels than control groups (p&#x202f;<&#x202f;0.05). One UCBA also reported a significant improvement in patient continence. Bias was assessed as moderate in the RCTs and high in the UCBAs.

Given rapid population ageing in Sub-Saharan Africa, alongside worsening deprivation, this paper offers an interrogation of existing evidence and exposes concomitant shortfalls in the knowledgebase. Scoping review methodology was employed using PRISMA Guidelines which systematically searched and screened three academic databases. At the global level, climate shifts and natural disasters, pandemics and epidemics such as Coronavirus-2019 and HIV/AIDS affect food insecurity. At a national level, food and welfare systems play a comparatively well-researched role in food insecurity among older persons. Community factors; levels of self-mobilisation or actions of civil society, and intrahousehold dynamics of kinship and associated resource distribution also proved important variables in determining food insecurity. Finally, demographic characteristics; age, marital status, gender, physical and cognitive abilities and coping mechanisms are discussed. In critical review, the work identifies two salient shortcomings in the understanding of food insecurity among older persons. One, extant research fails to account for path dependency, either within the lives of older persons, or socio-economic and political structures surrounding them. The findings, therefore, call for greater impetus upon the adoption of a life-course perspective. Two, scholars have failed to acknowledge older persons' role in shaping these structures and the food/welfare matrix at large. The work concludes by advocating for further theoretical development toward a comprehensive political economy of food insecurity, accounting for changes in the life-course of the individual, and the food, family and welfare systems in which they find themselves.}, }

This review examines the multifaceted effects of the COVID-19 pandemic on maternity staff and the challenges encountered during this period.<br><br>METHODS: This scoping review adhered to the methodologies outlined by Arksey &amp; O'Malley and the Joanna Briggs Institute. We searched six bibliographic databases for English and German articles published between January 2020 and September 2023 that addressed the pandemic's impact on maternity staff in OECD countries. The themes and subthemes were deductively established from the extracted results, synthesized into descriptive narratives and charted within a schematic diagram. The reporting followed the PRISMA-ScR statement.<br><br>RESULTS: This scoping review included 83 articles. Key findings were categorized into the two broader topics "structural challenges" and "mental health impacts on the workforce". Structural challenges included staff shortages, restructuring, inadequate personal protective equipment (PPE), transition to virtual communication, managing SARS-CoV-2 positive patients, and restrictions on accompanying persons. Mental health impacts were significant, with increased levels of anxiety, stress and moral dilemmas among staff. Despite these challenges, a strong sense of occupational solidarity was observed.<br><br>CONCLUSIONS: The findings emphasize the need for improved support systems for maternity care staff during pandemics to mitigate these adverse effects. Recommendations include better resource allocation, enhanced mental health support, and clear communication strategies to navigate future healthcare crises effectively. These results may inform pandemic preparedness for future health crises.<br><br>TRIAL REGISTRATIONS: This scoping review was registered with OSF on October 24th, 2023 and the published protocol is openly available via https://doi.org/10.17605/OSF.IO/AVYDX.}, }

Incidence in the pediatric population could reach 2 per 100,000 per year, and COVID-19 infection is a significant risk factor, which increases the possibility of having an infection by 40 times. Early detection results in catching the disease early and consequently improves outcomes. Clinical presentation of viral myocarditis in children could vary from mild prodromal symptoms to severe heart failure. Clinical examination, electrocardiogram, and chest X-ray may give clues for physiological and structural signs usually associated with the disease. However, they are inconclusive as they lack both accuracy and specificity. Biomarkers used to track the disease usually lack sensitivity and specificity. Cardiac magnetic resonance (CMR) is the imaging of choice to diagnose viral myocarditis by showing edema and late gadolinium enhancement. Point-of-care ultrasound has been approved as a good imaging method for early detection. It can be used as an effective screening tool for high-risk patients. Positron emission tomography scan is very sensitive in detecting disease early in its acute phase, especially if combined with CMR. All imaging studies are prone to interpretation bias, leading to a misdiagnosis. Endomyocardial biopsy is the gold standard method for diagnosis. However, it is time-consuming and ineffective as an early detection tool. Artificial intelligence (AI) helps with interpretation, decreasing bias, improving accuracy, and saving time and manpower. With more research and evidence, adopting AI-based methods to diagnose myocarditis in pediatrics could offer early detection, reduce costs, and save time for early intervention. Genetics helps identify inflammatory pathways involved in vulnerable patients, and genetic therapy may suppress disease progression by mitigating these pathways. Research focused on children is highly encouraged, and collaboration between healthcare institutions to develop telemedicine-based programs is influential.}, }

Datasets that linked insurance claims or EHR with external sources (e.g. public health HIV surveillance, social systems) had the richest findings. PLWH who maintained care for HIV and comorbidities, including COVID-19, had similar health outcomes to peers living without HIV. Mental health, substance use disorders, and HPV-related cancers remain prevalent in PLWH. HIV stigma and racial disparities in non-HIV comorbidity care were detected. These findings reinforce evidence of improving general health for PLWH as research and evidence-based treatment progress, and the utility of Big Data for PLWH in public health emergencies like COVID-19.

Randomized controlled trials assessing the effects of online exercise (OE) versus no exercise or face-to-face exercise (FFE) in healthy adults were included. Effect sizes (standardized mean difference [SMD]) were pooled using robust variance estimation. The quality of the included studies was assessed by 2 independent reviewers applying the PEDro scale, and publication bias was checked by means of funnel plots. To determine the certainty about the evidence, the results were rated by means of the GRADE (Grading of Recommendations, Assessment, Development, and Evaluations) criteria.<br><br>RESULTS: A total of 18 articles with moderate to high methodological quality (7/10 points on the PEDro scale), including a total of 3571 participants, were identified. Visual inspection of funnel plots provided indications of a publication bias for 2 out of 16 outcomes. According to the meta-analysis, OE was superior to no exercise regarding strength (SMD=0.61, 95% CI 0.06 to 1.15, n=5 studies), balance (SMD=0.52, 95% CI 0.06 to 0.99, n=4 studies), endurance (SMD=0.85, 95% CI -0.01 to 1.70, n=5 studies), PA (SMD=0.46, 95% CI 0.05 to 0.87, n=5 studies), depression (SMD=1.08, 95% CI -0.01 to 2.16, n=4 studies), mood or emotion (SMD=0.47, 95% CI 0.05 to 0.90, n=5 studies), mental well-being (SMD=0.79, 95% CI 0.06 to 1.52, n=4 studies), and self-efficacy (SMD=1.1, 95% CI 1.03 to 1.17, n=3 studies). Compared to FFE, OE was noninferior (P>.05) except for gait speed which improved more following FFE (SMD=0.25, 95% CI 0.24 to 0.26, n=2 studies). The certainty about the evidence (GRADE criteria) was low to moderate for all comparisons.<br><br>CONCLUSIONS: OE represents an effective strategy to improve PA, physical function, and mental health in healthy adults and may hence help combat physical inactivity. However, despite the encouraging findings, some limitations need to be tackled before drawing definitive conclusions. These, inter alia, include a small total number of studies and substantial between-trial heterogeneity for some outcomes.

We explored the implications of telehealth on the quality of care for Medicaid beneficiaries with ADHD and TS, highlighting the benefits, challenges, and policy considerations. Telehealth has increased access to behavioral health services, including for ADHD and TS, by reducing geographic and financial barriers to care. The expanded use of telehealth has allowed patients to more easily interact with health care providers, and it particularly benefits those with limited access to specialized care. However, challenges remain, such as concerns about stimulant misuse in online ADHD treatments and the limited privacy offered in home telehealth settings. Furthermore, disparities in broadband access may exacerbate existing inequalities in care. Despite telehealth's potential to increase access to specialized care, the quality of telehealth provided is not guaranteed. Current quality measures for Medicaid telehealth services, especially for ADHD and TS, are insufficient. While some Medicaid programs have integrated telehealth into quality reporting, a need exists for more tailored measures that assess the unique needs of people with ADHD and TS. We recommend the development of quality measures for ADHD and TS, performance improvement projects for these conditions, better alignment of Medicaid managed care oversight, and research into the long-term outcomes of telehealth for care of people with ADHD and TS. Such efforts would support continued Medicaid telehealth expansion while ensuring high-quality care.}, }

This phenomenon, termed post-COVID-19 condition and also known as long COVID, has been a source of controversy among physicians, as presentation of long COVID has been a somewhat mysterious constellation of signs and symptoms that seem mostly impervious to efficacious treatment. Although a considerable amount has been learned about the pathophysiology and other biomedical features of long COVID, the epidemiologic parameters of long COVID, including incidence and prevalence, are uncertain in the United States and globally. The best estimates are that millions of people have long COVID. Despite the declining incidence of COVID-19, the low case fatality of long COVID suggests that its prevalence is poised to continue to grow. This increasing prevalence of long COVID presents a challenge for the public health sector. Here, we examine the public health implications of long COVID. We offer policy recommendations, including ending congratulatory talk that the pandemic is over, encouraging more focused attention from the United States and global nongovernmental organizations, and establishing a multinational research initiative to better understand and respond to long COVID and other postviral and postinfectious chronic conditions. Although COVID-19 may not be as widespread and disruptive as in the early months of the pandemic, it would be a mistake to presume that, because the acute crisis is behind us, the pandemic is past.

This study explores how social media text mining can support these priorities by providing valuable insights into public sentiment, vaccine hesitancy, and the emergence of novel viral strains. By analyzing online conversations, researchers can gain a deeper understanding of questions and concerns surrounding booster shots, enabling the development of targeted public health initiatives to address vaccine reluctance and promote booster uptake. Moreover, social media data can assist governments in identifying areas with high vaccine hesitancy or low vaccination rates, allowing for the strategic allocation of resources and interventions. Importantly, this study also highlights the potential of social media text mining to serve as an early warning system for new viral variants. By monitoring discussions related to symptoms and outbreaks, researchers can detect risks before they become widespread, informing timely public health responses and mitigation strategies. Complementing these surveillance efforts, the study emphasizes the significance of pattern prediction, which leverages historical data and models to forecast disease dynamics and guide resource allocation. By integrating social media data with epidemiological and clinical information, more accurate and responsive pandemic management strategies can be implemented. Ultimately, this research underscores the critical role of continuous pandemic monitoring and pattern prediction in the post-vaccination phase, enabling evidence-based decision-making and the effective control of infectious diseases. The insights gained from this study can inform the development of robust, data-driven frameworks for pandemic preparedness and response in the aftermath of widespread vaccination campaigns.}, }

Flavivirus vaccines are believed to confer protection primarily through antibody responses; however, the role of T cells in vaccine immunity remains less explored despite demonstrated contribution in the response to natural infection. This review examines T cell responses induced by licensed or developing flavivirus vaccines, their contribution to protection, and key findings highlighting the importance of cellular immunity. We discuss the role of memory T cells, including CD4+ and CD8+ subsets, in flavivirus vaccine-induced immunity and compare the immunogenicity of live attenuated versus inactivated vaccines. We also discuss the significance of T cell immunity, cross-reactivity, and vaccine platform design in shaping durable and broad protection. Additionally, we broaden the discussion toward other human RNA viruses, including the influenza virus and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). A better understanding of the role of T cell immunity will be essential for optimizing the use of current flavivirus vaccines and developing next-generation approaches capable of providing long-lasting immunity against emerging and re-emerging flavivirus threats.}, }

These infections have had recent publications about neurodevelopmental impacts.<br><br>RECENT FINDINGS: Children with congenital cytomegalovirus infection, especially those with symptomatic infection, are at a high risk for developmental delays. They also seem to be at an increased risk for autism spectrum disorder. Studies indicate that prenatal exposure to severe acute respiratory syndrome coronavirus 2 may also be a risk factor for developmental delay and that all children exposed prenatally should be followed more closely for early neurodevelopment. Children with congenital Zika syndrome and birth defects are at risk for a range of neurodevelopmental sequalae and at high risk for early mortality. However, normocephalic children with antenatal Zika virus exposure are also at risk for a range of neurodevelopmental effects including lower cognitive performance at school age.<br><br>SUMMARY: Congenital and perinatal infectious exposures increase the risk for impaired child neurodevelopment.

Its importance has been recently highlighted by COVID-19. However, IAQ significantly impacts public health, concerning not only respiratory, but also cardiovascular diseases. The World Health Organization defines One Health as "an approach to designing and implementing programmes, policies, legislation and research in which multiple sectors communicate and work together to achieve better public health outcomes". This scoping review fills a gap in the literature by exploring the One Health approach, which integrates human, animal, and environmental health, applied to the study of airborne transmission. We searched various databases for articles that assessed microbiological IAQ using the One Health approach. Eligible documents assessed air contamination, with a focus on infectious threats and antimicrobial resistance. Our work maps the topics covered, the methodologies employed, and the evidence gaps identified. Our literature search yielded 8471 articles, from which 18 studies were selected for detailed analysis. Findings indicate that the One Health approach effectively addresses the complex challenge of airborne microbiological contamination. This approach comprises a comprehensive view of topics, contexts, agents and methodologies employed to study airborne transmission in indoor spaces. The agents included range from influenza, legionella and others, to the dispersal of mycotoxins and antibiotic resistance genes. The role of animals in diverse human-animal interaction settings was highlighted as a significant factor influencing IAQ, particularly in relation to zoonotic spillover risks, and the airborne transmission of antimicrobial resistance. The review also identified evidence gaps in research and highlighted the need for interdisciplinary collaboration. Incorporating One Health principles into IAQ research is essential for developing comprehensive health strategies that can address both current and emerging infectious threats. Future research should prioritise settings involving animal-human indoor interactions, focusing on workplace contamination, zoonotic spillover, emergent threats, and the airborne transmission of antimicrobial resistance, to ensure a robust framework for safeguarding global health.}, }

Andrographis paniculata (Burm. f.) Nees (AP), with known anti-inflammatory and antiviral properties, has been explored as adjunctive therapy for COVID-19, but its clinical evidence remains inconclusive. We hypothesized that AP-derived compounds may improve symptoms and inflammatory responses in mild-to-moderate COVID-19. This systematic review and meta-analysis aimed to evaluate the clinical and biological effects of AP-derived compounds, its extract (APE), or its derivatives in patients with mild-to-moderate COVID-19. A systematic search was conducted in PubMed, EMBASE, CENTRAL, and EBSCO Open Dissertations from January 2020 to October 2024. Randomized controlled trials (RCTs) examining the effects of single-herb AP products compared to antivirals or supportive care (SC) in patients with mild-to-moderate COVID-19 were included if they reported clinical recovery, fever or cough resolution, C-reactive protein (CRP), or interleukin-6 (IL-6) levels. Risk of bias (RoB) was assessed using Cochrane RoB 2.0. A random-effects model was used to estimate pooled effects of included trials, expressed as relative risk (RR) and mean difference (MD) with 95% confidence intervals (CIs). Six RCTs involving 660 adults aged 18 to 60 were included. Compared to antivirals or SC, single-herb AP products showed no significant improvements in fever resolution (RR 1.12; 95%CI 0.90 to 1.38; I[2] = 0.0%) or cough resolution (RR 0.98; 95%CI 0.74 to 1.31; I[2] = 47.0%). No significant differences were observed in serum CRP (MD -0.04; 95%CI -0.26 to 0.18; I[2] = 0.0%) and IL-6 levels (MD -0.07; 95%CI -0.17 to 0.03; I[2] = 0.0%). While some studies not included in the meta-analysis suggested early reductions in CRP and IL-6, the findings were inconsistent. RoB was high for fever resolution but low for biomarkers. Mild adverse events, primarily liver enzyme elevations, resolved without severe complications. Our systematic review and meta-analysis suggest a potential role for AP extract and its derivatives as adjunctive therapy for COVID-19, with trends indicating possible benefits in symptom improvement and inflammation reduction. These findings highlight the need for further research to explore AP as a complementary therapeutic strategy in COVID-19 management.<br><br>https://www.crd.york.ac.uk/PROSPERO/view/CRD42024608858, identifier CRD42024608858.}, }
