covid-19

Coronavirus disease 2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS coronavirus 2, or SARS-CoV-2), a virus closely related to the SARS virus. The disease was discovered and named during the 2019-20 coronavirus outbreak. Those affected may develop a fever, dry cough, fatigue, and shortness of breath. A sore throat, runny nose or sneezing is less common. While the majority of cases result in mild symptoms, some can progress to pneumonia and multi-organ failure. The infection is spread from one person to others via respiratory droplets produced from the airways, often during coughing or sneezing. Time from exposure to onset of symptoms is generally between 2 and 14 days, with an average of 5 days. The standard method of diagnosis is by reverse transcription polymerase chain reaction (rRT-PCR) from a nasopharyngeal swab or sputum sample, with results within a few hours to 2 days. Antibody assays can also be used, using a blood serum sample, with results within a few days. The infection can also be diagnosed from a combination of symptoms, risk factors and a chest CT scan showing features of pneumonia. Correct handwashing technique, maintaining distance from people who are coughing and not touching one's face with unwashed hands are measures recommended to prevent the disease. It is also recommended to cover one's nose and mouth with a tissue or a bent elbow when coughing. Those who suspect they carry the virus are recommended to wear a surgical face mask and seek medical advice by calling a doctor rather than visiting a clinic in person. Masks are also recommended for those who are taking care of someone with a suspected infection but not for the general public. There is no vaccine or specific antiviral treatment, with management involving treatment of symptoms, supportive care and experimental measures. The case fatality rate is estimated at between 1% and 3%. The World Health Organization (WHO) has declared the 2019-20 coronavirus outbreak a Public Health Emergency of International Concern (PHEIC). As of 29 February 2020, China, Hong Kong, Iran, Italy, Japan, Singapore, South Korea and the United States are areas having evidence of community transmission of the disease.

Renin as a Prognostic Marker in Intensive Care and Perioperative Settings: A Scoping Review.

Anesthesia and analgesia, 138(5):929-936.

Serum renin increases in response to sympathetic nerve activation and hypotension. Recent studies have reported the association of serum renin levels with adverse clinical outcomes in acute care settings. This scoping review aimed to systematically review the available literature on renin as a prognostic marker in intensive care and perioperative patients. We searched for studies published since inception until March 31, 2023, which assessed the association between serum renin levels and clinical outcomes or the effect of synthetic angiotensin II administration on serum renin levels in critically ill and perioperative patients in PubMed, Embase, and the Cochrane Library. The primary outcome was mortality at the longest follow-up; the secondary outcomes were adverse renal outcomes (ie, acute kidney injury, the need for renal replacement therapy, and major adverse kidney events), hemodynamic instability, outcomes to angiotensin II administration, and prognostic performance for mortality when compared with lactate. Among the 2081 studies identified, we included 16 studies with 1573 patients (7 studies on shock, 5 on nonspecific critical illness, 2 on cardiac surgery, 1 on noncardiac surgery, and 1 on coronavirus disease 2019). A significant association between serum renin levels and poor outcomes was identified in 14 studies, with 10 studies demonstrating an association with mortality. One post hoc analysis found that angiotensin II administration reduced mortality in patients with markedly elevated renin values. Two studies showed that renin was superior to lactate as a prognostic marker of mortality. Our scoping review showed that elevated serum renin levels may be associated with clinically relevant outcomes among various perioperative and intensive care populations. Increased serum renin levels may identify patients in which synthetic angiotensin II administration improves clinical outcomes and may outperform serum lactate in predicting mortality.

Therapeutic considerations for prevention and treatment of thrombotic events in COVID-19.

Thrombosis update, 10:100126.

Thrombosis is a known complication of SARS-CoV-2 infection, particularly within a severely symptomatic subset of patients with COVID-19 disease, in whom an aggressive host immune response leads to cytokine storm syndrome (CSS). The incidence of thrombotic events coinciding with CSS may contribute to the severe morbidity and mortality observed in association with COVID-19. This review provides an overview of pharmacologic approaches based upon an emerging understanding of the mechanisms responsible for thrombosis across a spectrum of COVID-19 disease involving an interplay between immunologic and pro-thrombotic events, including endothelial injury, platelet activation, altered coagulation pathways, and impaired fibrinolysis.

DeSa COVID-19: Deep salient COVID-19 image-based quality assessment.

Journal of King Saud University. Computer and information sciences, 34(10):9501-9512.

This study offers an advanced method to evaluate the coronavirus disease 2019 (COVID-19) image quality. The salient COVID-19 image map is incorporated with the deep convolutional neural network (DCNN), namely DeSa COVID-19, which exerts the n-convex method for the full-reference image quality assessment (FR-IQA). The glaring outcomes substantiate that DeSa COVID-19 and the recommended DCNN architecture can convey a remarkable accomplishment on the COVID-chestxray and the COVID-CT datasets, respectively. The salient COVID-19 image map is also gauged in the minuscule COVID-19 image patches. The exploratory results attest that DeSa COVID-19 and the recommended DCNN methods are very good accomplishment compared with other advanced methods on COVID-chestxray and COVID-CT datasets, respectively. The recommended DCNN also acquires the enhanced outgrowths faced with several advanced full-reference-medical-image-quality-assessment (FR-MIQA) techniques in the fast fading (FF), blocking artifact (BA), white noise Gaussian (WG), JPEG, and JPEG2000 (JP2K) in the distorted and undistorted COVID-19 images. The Spearman's rank order correlation coefficient (SROCC) and the linear correlation coefficient (LCC) appraise the recommended DCNN and DeSa COVID-19 fulfillment which are compared the recent FR-MIQA methods. The DeSa COVID-19 evaluation outshines 2.63% and 2.62% higher compared the recommended DCNN, and 28.53% and 29.01% esteem all of advanced FR-MIQAs methods on SROCC and LCC measures, respectively. The shift add operations of trigonometric, logarithmic, and exponential functions are mowed down in the computational complexity of the DeSa COVID-19 and the recommended DCNN. The DeSa COVID-19 more superior the recommended DCNN and also the other recent full-reference medical image quality assessment methods.

The role of micronutrients in the management of COIVD-19 and optimizing vaccine efficacy.

Human nutrition & metabolism, 27:200141.

Since COVID-19 was declared as a pandemic, a race between researchers has begun to deeply examine the mechanism of the virus and how to combat it. Few clinical investigations and studies have paid attention to the role of micronutrients in the disease's course and how it may affect the disease outcomes. Micronutrients have a noticeable effect on the host immune system regulation, as well as micronutrients insufficiencies where they can affect the host immune response against SARS-CoV-2 by, for example, altering the production and the function of the inflammatory cytokines such as IFN-γ, IFN-α, TNF and interleukins. Recent studies have shown that low levels of vitamin D, vitamin C, vitamin A, zinc, selenium, copper and magnesium have a great clinical impact on COVID-19 patients, where, they are linked to prolong hospital stay, increase the mortality rate and raise the complications rate related not only to the respiratory system but also to the other systems. Optimizing the need for these micronutrients will act as a productive factor by decreasing the incidence of COVID-19 infection, lowering the rate of complications, and improving the disease prognosis and outcomes. Optimal micro-nutrition supports and contributes to the efficiency of COVID-19 vaccine. The aim of this review is to highlight the role of different micronutrients in the management of COVID-19 and optimizing vaccines, and to revile the clinical effects of micronutrients deficiencies on patients with COVID-19.

Wet wipes contribution to microfiber contamination under COVID-19 era: An important but overlooked problem.

Environmental challenges (Amsterdam, Netherlands), 5:100267.

Wet wipes for disinfection, sanitizing, and medical purposes, like personal protective equipment, have witnessed an upsurge in production and use as a result of COVID-19 outbreak. They are a potential source of microfibers and have recently been found in COVID-19 plastic litter survey campaigns conducted in a few marine environments around the world. This mini-review highlights wet wipes as a one of the key debris items contributing to the growing COVID-19-related microplastic pollution, and there are significant gaps in our understanding of microfiber release under different environmental conditions, morphological, and chemical degradation signatures, necessitating a comprehensive study of disinfectant wipes. Thus, we urge microplastic researchers to investigate the environmental implications of wet wipes in order to keep the total estimate of the plastic problem up to date and manage the associated environmental challenges.

[Respiratory physiotherapy in post-COVID-19: a decision-making algorithm for clinical practice].

Open respiratory archives, 4(1):100139.

The outbreak of COVID-19 has posed a great challenge for the healthcare system which has been later aggravated by the need of managing clinical manifestations and potential sequelae in COVID-19 survivors. In this context, respiratory Physiotherapy emerges as a cornerstone in the interdisciplinary management warranted in this population. Given that the implementation and resources available for the interdisciplinary therapeutic interventions in Spain is scarce, it is essential to perform a comprehensive, exhaustive and personalised assessment. This will allow us to establish more accurate selection criteria in order to optimise the use of existing human and material resources. To this end, we propose here a decision-making algorithm for clinical practice to assess the clinical manifestations in people recovered from COVID-19 based on well-established, validated tests and assessment tools. This algorithm can be used at any clinical practice environment (primary care/community or hospital-based), combined with a patient-centered model and the use of community and e-Health resources and its application to improve the Physiotherapy care of these patients in the COVID-19 era.

Declining carbon emission/concentration during COVID-19: A critical review on temporary relief.

Carbon trends, 5:100131.

In December 2019 the deadly pandemic COVID-19 traumatized mankind through its lethal impact. To seize the outbreak, nationwide/region-based lockdown strategies were adopted by most of the COVID-19 affected countries. This in turn resulted in restricted transportation via surface, water, and air, as well as significantly reduced working hours of the industry sectors, so on and so forth. The obvious outcome was a sudden discernible decline in atmospheric adulteration. Accordingly, the anthropogenic emissions at the global and regional/local scales were examined during the lockdown period by several researchers using both or either satellite-based and ground-based monitoring. Among several other air-contaminants, carbon has a dominant toxicological profile causing adverse health effects and thereby attracting researches interest in carbon-release probing during the systematic confinement period imposed by the ruling authorities across the globe. The results of those studies indicated a confirmed decline in carbon emission/concentration making the air more breathable for the period. In this review, the studies related to anthropogenic emissions of carbon during the lockdown period are accounted for by compiling the recently reported data from published articles.

The role of airborne particles and environmental considerations in the transmission of SARS-CoV-2.

Geoscience frontiers, 12(5):101189.

Corona Virus Disease 2019 (COVID-19) caused by the novel coronavirus, results in an acute respiratory condition coronavirus 2 (SARS-CoV-2) and is highly infectious. The recent spread of this virus has caused a global pandemic. Currently, the transmission routes of SARS-CoV-2 are being established, especially the role of environmental transmission. Here we review the environmental transmission routes and persistence of SARS-CoV-2. Recent studies have established that the transmission of this virus may occur, amongst others, in the air, water, soil, cold-chain, biota, and surface contact. It has also been found that the survival potential of the SARS-CoV-2 virus is dependent on different environmental conditions and pollution. Potentially important pathways include aerosol and fecal matter. Particulate matter may also be a carrier for SARS-CoV-2. Since microscopic particles can be easily absorbed by humans, more attention must be focused on the dissemination of these particles. These considerations are required to evolve a theoretical platform for epidemic control and to minimize the global threat from future epidemics.

The role of continuous renal replacement therapy (Crrt) in Coronavirus disease 2019 (Covid-19) patients.

Trends in anaesthesia & critical care, 39:12-18.

Even without the presence of the novel Coronavirus disease 2019 (COVID-19), acute kidney injury has been a serious problem in medicine for decades, with mortality rate up to 70% among those who eventually required renal replacement therapy, and the number has not changed significantly for the last 30 years despite major advances in technology and experience. On the other hand, even without acute kidney injury, COVID-19 was a major cause of death globally in the year 2020, but the occurrence of acute kidney injury among COVID-19 patients is an independent risk factor of increased mortality. Continuous renal replacement therapy has been recommended to treat acute kidney injury in COVID-19 patients instead of conventional intermittent hemodialysis. Moreover, its use might have another beneficial role in stopping the progression of severe COVID-19 by removing pro-inflammatory cytokines during cytokine storm syndrome, which is postulated as the pathophysiology behind severe and critically severe cases of COVID-19. This review will cover a brief history of continuous renal replacement therapy and its modalities, before digging up more into its use in COVID-19 patients, including the optimum filtration dose and timing, membrane filtration used, vascular access, anticoagulation therapy, and drug dosing adjustment during continuous renal replacement therapy.

Food science and COVID-19.

Food science and human wellness, 10(1):1-5.

Theories proposing a role of specific dietary components or food supplements in the prevention or treatment of COVID-19 have received extensive social media coverage. A multitude of scientific publications have also pointed to the importance of food and nutrition in combating the COVID-19 pandemic. The present perspective critically addresses the question of what food science can actually contribute in this context. Animal studies suggest that micronutrients, food bioactives or functional foods may carry the potential to augment viral defense. However, the specific roles of food components in viral infectious diseases in humans remain unclear. Rigorous research assessing the efficacy of food compounds in counteracting infections would require long-term randomized controlled trials in large samples. While no foods, single nutrients or dietary supplements are capable of preventing infection with COVID-19, a balanced diet containing sufficient amounts of macronutrients and diverse micronutrients is a prerequisite of an optimally functioning immune system. High-energy diets and obesity are major risk factors for a more severe course of COVID-19. Therefore, population-wide body weight control and weight reduction in overweight people are important preventive measures. Diet may play a beneficial role in maintaining a healthy body weight and preventing non-communicable conditions.

Clinica e investigacion en ginecologia y obstetricia pii:S0210-573X(23)00076-X [Epub ahead of print].

There is very limited evidence regarding the use of prone position as part of the treatment of severe ARDS in pregnant patients. Currently, recommendations for invasive ventilatory management in this population are very scarce and are based on the extrapolation of conclusions obtained in studies of non-pregnant patients. The available literature asserts that the anatomy and physiology of the pregnant woman undergoes complex adaptive changes that must be considered during invasive ventilatory support and prone position. With prone ventilation, the benefits obtained for the couple far outweigh the eventual risks. Adequate programming of the mechanical ventilator correlates with a clear and simple concept: individualization of support. In any case, the decision on the timing of termination of pregnancy should be based on adequate multidisciplinary clinical judgment and should be supported by strict monitoring of the product.

The neurological manifestations and complications of the acute phase of COVID-19 are numerous. They mainly concern the central nervous system in the frequent forms of encephalopathy, encephalitis and neurovascular pathologies. Peripheral neurological manifestations mainly include acute polyneuropathies such as Guillain-Barré syndrome and intensive care neuromyopathies. Most of these manifestations were described during the first wave of the pandemic. The epidemiological, clinical, paraclinical, pathophysiological and therapeutic aspects are addressed in this general review of the literature published from 2020 to early 2023.

The plausible effects of wearing face masks on sports performance - A scoping review.

Science & sports pii:S0765-1597(23)00133-8 [Epub ahead of print].

OBJECTIVES: The objectives of this scoping review are to discuss, firstly, the positive aspects of wearing face masks during training (such as a barrier to COVID-19 transmission, air pollutant exposure, and adding load on respiratory resistance flow); secondly, the negative aspects (adverse effects on body temperature and hypoxia risks); and thirdly, the training responses of wearing face masks on aerobic and anaerobic performance.

NEWS: Besides social distancing and hand hygiene, wearing a face mask is proposed to be the prime advocacy for virus containment. During the period of high risk of contamination, the return to sport guidelines proposed by international and national sport federations included wearing face masks during training sessions. However, it is necessary to discuss the pros and cons of wearing face masks during exercise.

PROSPECTS: Although it was essential to wear a face mask during exercise or sport-specific training, there is conflicting evidence on the implications of the use of face masks on physical, physiological as well as psychological well-being or performance. Based on the conflicting empirical findings and anecdotal evidence, certain recommendations have been made for adequate use of face masks during exercise; both to break the chain of transmission and prevent the physiological compromise expected from wearing face masks during exercise. The present review can help stakeholders balance sport guidelines in the event of a respiratory virus pandemic with athlete safety.

CONCLUSION: Conflicting evidence of mechanistic links between the dose of exercise and the possible adverse effects associated with exercising with face masks is available. Adequately powered studies with strong methodological quality on appropriate selection of masks and usage based on the intensity, duration, and type of sport, age, and gender is needed now for the stakeholders to make informed decisions with respect to exercising with face masks.

Seminal fluid changes in the COVID-19 era: During infection and Post-vaccination.

Gynecology and obstetrics clinical medicine, 3(2):88-93.

Coronavirus disease 2019 (COVID-19) predilection for angiotensin-converting enzyme 2 (ACE2) receptors allows its entrance and replication; however, they are not biochemically required for viral fusion into the cell membrane. Testicular tissue has abundant ACE2 receptors, making it a target for the COVID-19 virus. Seminal fluid parameters are measures of male fertility. Changes in semen parameters have been caused by coronavirus disease and vaccines. Some attribute that effect to direct hematogenic spread to the testis; others propose that the excessive immunological response triggered by the infection causes a deleterious effect. An unsubstantiated claim questioned whether the SARS-CoV-2 vaccine could trigger an unintentional immunological response that would impair male fertility once receiving the vaccine. Extensive research confirms the transient nature of those changes that affect sperm motility and count with full recovery post-COVID-19 infection and after vaccination. The vaccine's safety was reaffirmed; however, there are currently no recommendations for screening sperm donors. Research is warranted to guarantee the safety of couples undergoing assisted reproduction.

High flow nasal oxygen (HFNO) in the treatment of COVID-19 infection of adult patients from - An emergency perspective: A systematic review and meta-analysis.

Trends in anaesthesia & critical care, 50:101238.

Coronavirus disease 2019 (COVID-19) is an infectious disease caused by SARS-CoV-2, which was first discovered in Wuhan, China. The disease has grown into a global pandemic causing mild to moderate symptoms in most people. The disease can also exhibit serious illnesses, especially for patients with other chronic diseases such as cardiovascular diseases, diabetes, chronic respiratory disease, or cancer. In such cases of severe illness, high flow nasal oxygen (HFNO) has been used to provide oxygenation to COVID-19 patients. However, the efficiency of HFNO remains uncertain, prompting the conduction of this systematic review to evaluate the effectiveness of the therapy. A thorough search for relevant and original articles was carried out on five electronic databases, including ScienceDirect, PubMed, Cochrane Library, Embase, and Google Scholar. No time limitation was placed during the search as it included all the articles related to COVID-19 from 2019 to 2022. The search strategy utilized in this systematic review yielded 504 articles, of which only 10 met the eligibility criteria and were included. Our meta-analysis reveals that HFNO success rate was higher than HFNO failure rates (0.52 (95% CI; 0.47, 0.56) and 0.48 (95% CI; 0.44, 0.53), respectively), however, the difference was statistically insignificant. HFNO was associated with a significant decrease in mortality and intubation rates (0.28 (95% CI; 0.19, 0.39) and 0.28 (95% CI; 0.18, 0.41), respectively). Our statistical analysis has shown that significantly lower ROX index (5.07 ± 1.66, p = 0.028) and PaO2/FiO2 (100 ± 27.51, p = 0.031) are associated with HFNO failure, while a significantly lower respiratory rate (RR) (23.17 ± 4.167, p = 0.006) is associated with HFNO success. No statistically significant difference was observed in SpO2/FiO2 ratio between the HFNO success and failure groups (154.23 ± 42.74 vs. 124.025 ± 28.50, p = 0.62, respectively). Based on the results from our meta-analysis, the success or failure of HFNO in treating COVID-19 adult patients remains uncertain. However, HFNO has been shown to be an effective treatment in reducing mortality and intubation rates. Therefore, HFNO can be recommended for COVID-19 patients but with close monitoring and should be carried out by experienced healthcare workers.

Immunosuppressed persons are a heterogeneous population that represents approximately 3 % of the adult population. They are more vulnerable to infectious agents, such as SARS-CoV-2. This is reflected by a reduced response to vaccination, a higher rate of progression towards a severe form of the disease, and recurrent or persistent infections associated with intra-host viral evolution. This review summarizes the evidence regarding vaccine efficacy, clinical and virological singularities, and the management in immunosuppressed patients.

Overview of the recent advances in porcine epidemic diarrhea vaccines.

Veterinary journal (London, England : 1997), 304:106097.

Vaccination is the most effective means of preventing and controlling porcine epidemic diarrhea (PED). Conventional vaccines developed from porcine epidemic diarrhea virus (PEDV) GI-a subtypes (CV777 and SM98) have played a vital role in preventing classical PED. However, with the emergence of PEDV mutants in 2010, conventional PEDV GI-a subtype-targeting vaccines no longer provide adequate protection against PEDV GII mutants, thereby making novel-type PED vaccine development an urgent concern to be addressed. Novel vaccines, including nucleic acid vaccines, genetically engineered subunit vaccines, and live vector vaccines, are associated with several advantages, such as high safety and stability, clear targeting, high yield, low cost, and convenient usage. These vaccines can be combined with corresponding ELISA kits to differentiate infected from vaccinated animals, which is beneficial for disease confirmation. This review provides a detailed overview of the recent advancements in PED vaccines, emphasizing on the research and application evaluation of novel PED vaccines. It also considers the future directions and challenges in advancing these vaccines to widespread use in clinics.

Telemedicine-Based Cognitive Examinations During COVID-19 and Beyond: Perspective of the Massachusetts General Hospital Behavioral Neurology & Neuropsychiatry Group.

The Journal of neuropsychiatry and clinical neurosciences, 36(2):87-100.

Telehealth and telemedicine have encountered explosive growth since the beginning of the COVID-19 pandemic, resulting in increased access to care for patients located far from medical centers and clinics. Subspecialty clinicians in behavioral neurology & neuropsychiatry (BNNP) have implemented the use of telemedicine platforms to perform cognitive examinations that were previously office based. In this perspective article, BNNP clinicians at Massachusetts General Hospital (MGH) describe their experience performing cognitive examinations via telemedicine. The article reviews the goals, prerequisites, advantages, and potential limitations of performing a video- or telephone-based telemedicine cognitive examination. The article shares the approaches used by MGH BNNP clinicians to examine cognitive and behavioral areas, such as orientation, attention and executive functions, language, verbal learning and memory, visual learning and memory, visuospatial function, praxis, and abstract abilities, as well as to survey for neuropsychiatric symptoms and assess activities of daily living. Limitations of telemedicine-based cognitive examinations include limited access to and familiarity with telecommunication technologies on the patient side, limitations of the technology itself on the clinician side, and the limited psychometric validation of virtual assessments. Therefore, an in-person examination with a BNNP clinician or a formal in-person neuropsychological examination with a neuropsychologist may be recommended. Overall, this article emphasizes the use of standardized cognitive and behavioral assessment instruments that are either in the public domain or, if copyrighted, are nonproprietary and do not require a fee to be used by the practicing BNNP clinician.

Telemedicine and Its Perceptions in a Border Community: A Review of How Health Care Technology Has Helped Increase Access.

Telemedicine journal and e-health : the official journal of the American Telemedicine Association, 30(4):987-993.

Introduction: Telemedicine is a practical way of offering medical services to remote and underserved areas. During the COVID-19 pandemic, telemedicine has provided convenient access to health care and has overcome barriers such as distance that prevent patients from receiving care. Border populations are impacted by this change in health care delivery. The goal of this study was to investigate how a border patient population perceives their experiences with telemedicine. Methods: We utilized telephone surveys of patients who had a recent telehealth visit at the Texas Tech University Health Science Center (TTUHSC) Family Medicine Center clinic in El Paso, Texas. Survey measures included patients' demographics, a quality assessment of the patients' most recent telehealth visit and their experience, a comparison of the patients' telehealth visit to past in-person visits, and a rating of their telehealth visit. Result: Over 2,000 individuals (n = 2,040), primarily Hispanic females, older than the age of 44 years were identified for potential inclusion in the study. Of these, 928 had a contact attempt, of which 1,378 could not be contacted, 592 were invited, 70 declined leading to a response rate of 67.6% (number invited/completed the survey). Most patients agreed that during their most recent telehealth visit their clinician listened well (98.7%), spent adequate time with them (98.2%), was prompt (94.5%), explained things well (98.0%), and was someone they would recommend to others (97.2%). When comparing telehealth to in-person visits, patients reported the following: less wait time, easier convenience, and similar quality between virtual and in-person visits. Patients rated both their likelihood of using telehealth again and their likelihood of recommending telehealth to others as an 8.68 out of 10, on average. Patients 65 years old or older had 3.17 times greater likelihood of satisfaction with virtual visits when compared with patients younger than 45 years old (confidence interval [95% CI], 1.24-11.11). Patients also had less satisfaction with virtual visits if they had lower educational attainment (odds ratio = 0.10; 95% CI, 0.01-0.81). Conclusions: We found that individuals in a border community had a positive experience with telehealth primary care visits. This approach may improve access to health care.

COVID-19 infection and metabolic comorbidities: Mitigating role of nutritional sufficiency and drug - nutraceutical combinations of vitamin D.

Human nutrition & metabolism, 31:200179.

The vulnerability of human health is amplified in recent times with global increase in non-communicable diseases (due to lifestyle changes and environmental insults) and infectious diseases (caused by newer pathogens and drug-resistance strains). Clinical management of diseases is further complicated by disease severity caused by other comorbid factors. Drug-based therapy may not be the sole approach, particularly in scenarios like the COVID-19 pandemic, where there is no specific drug against SARS-CoV-2. Nutritional interventions are significant in armouring human populations in disease prevention, and as adjunctive therapy for disease alleviation. Amidst ongoing clinical trials to determine the efficacy of Vit. D against infections and associated complications, this review examines the pleiotropic benefits of nutritional adequacy of vitamin D (Vit. D) in combating viral infections (COVID-19), its severity and complications due to co-morbidities (obesity, diabetes, stroke and Kawasaki disease), based on research findings and clinical studies. Supplements of Vit. D in combination with other nutrients, and drugs, are suggested as promising preventive-health and adjunct-treatment strategies in the clinical management of viral infections with metabolic comorbidities.

Utilization of pumpkin, pumpkin powders, extracts, isolates, purified bioactives and pumpkin based functional food products: A key strategy to improve health in current post COVID 19 period: An updated review.

Applied food research, 2(2):100241.

Progression of today's world has been given setback due to the adversity of a novel, viral and deadly outbreak COVID 19, which raised the concerns of the scientists, researchers and health related officials about the inherent and adaptive immune system of the living body and its relation with healthy diet balanced with pharma foods. Choice of right food can help to build and boost adaptive immunity and pumpkin due to excellent profile of functional and nutraceutical constituents must be the part of both infected and non-infected person's daily diet. Vitamins, minerals, phenolic acids, essential oils, peptides, carotenoids and polysaccharides present in pumpkin could accommodate the prevailing deficiencies in the body to fought against the pathogens. Pumpkins are well equipped with nutraceuticals and functional ingredients therefore, consumption and processing of this remarkable fruit must be encouraged as pharma food due to its antihyperlipidemic, antiviral, anti-inflammatory, antihyperglycemic, immunomodulatory, antihypertensive, antimicrobial and antioxidant potential, and these pharmacological properties of pumpkin are directly or indirectly related to the COVID 19 outbreak. Utilization of pumpkin has a domain in the form of powders, extracts, isolates, and pumpkin incorporated food products. A wide range of healthy, nutritious and functional food products has been developed from pumpkin, which includes juice, soup, porridge, chips, biscuits, bread, cake, bar and noodles. In recent times some innovative and novel technologies have been applied to process and preserve pumpkin for its enhanced shelf life and bioaccessibility of nutrients. Need of healthy eating in current post COVID 19 period is very crucial for healthy population, and medicinal foods like pumpkin, and bioactive compounds present in this functional food could play a vital role in developing a healthy community around the globe.

Guillain-Barre syndrome: An autoimmune disorder post-COVID-19 vaccination?.

Clinical immunology communications, 2:1-5.

SARS-CoV-2 causes Coronavirus Disease 2019 (COVID-19), an infectious condition that can present none or one or more of these symptoms: fever, cough, headache, sore throat, loss of taste and smell, aches, fatigue and musculoskeletal pain. For the prevention of COVID-19, there are vaccines available including those developed by Pfizer, Moderna, Sinovac, Janssen, and AstraZeneca. Recent evidence has shown that some COVID-19-vaccinated individuals can occasionally develop as a potential side effect Guillain-Barre syndrome (GBS), a severe neurological autoimmune condition in which the immune response against the peripheral nerve system (PNS) can result in significant morbidity. GBS had been linked previously to several viral or bacterial infections, and the finding of GBS after vaccination with certain COVID-19, while rare, should alert medical practitioners for an early diagnosis and targeted treatment. Here we review five cases of GBS that developed in different countries after COVID-19 vaccination.

COVID-19 vaccination in pregnancy: A review of maternal and infant benefits.

Gynecology and obstetrics clinical medicine, 2(3):124-128.

Pregnant women with COVID-19 are more likely to be admitted to the intensive care unit and their babies born prematurely. Clinical trials excluded pregnant women from the vaccine and safety data were limited. However, an increasing number of studies have demonstrated the safety and immunogenicity of the COVID-19 vaccines for pregnant women and their babies including evidence of maternal transfer of antibodies. In addition to these benefits, the vaccines are proved to be effective for both the pregnant women and infants. The current evidence supports the safety, immunogenicity of the COVID-19 vaccine and its effectiveness in reducing the theoretical risk of the infection among pregnant women and their infants. This review summarizes the recent data on the beneficial effects of COVID-19 immunization on both the pregnant mother and infant.

The interplay between inflammation and thrombosis in COVID-19: Mechanisms, therapeutic strategies, and challenges.

Thrombosis update, 8:100117.

Coronavirus disease 2019 (COVID-19), caused by a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), can cause life-threatening pathology characterized by a dysregulated immune response and coagulopathy. While respiratory failure induced by inflammation is the most common cause of death, micro-and macrovascular thrombosis leading to multiple organ failure are also causes of mortality. Dysregulation of systemic inflammation observed in severe COVID-19 patients is manifested by cytokine release syndrome (CRS) - the aberrant release of high levels of proinflammatory cytokines, such as IL-6, IL-1, TNFα, MP-1, as well as complement. CRS is often accompanied by activation of endothelial cells and platelets, coupled with perturbation of the balance between the pro-and antithrombotic mechanisms, resulting in thrombosis. Inflammation and thrombosis form a vicious circle, contributing to morbidity and mortality. Treatment of hyperinflammation has been shown to decrease thrombosis, while anti-thrombotic treatment also downregulates cytokine release. This review highlights the relationship between COVID-19-mediated systemic inflammation and thrombosis, the molecular pathways involved, the therapies targeting these processes, and the challenges currently encountered.

Venous thromboembolism risk, prophylaxis and management in cancer patients with COVID-19: An unmet medical need.

Thrombosis update, 6:100098.

Cancer patients exhibit an increased risk of venous thromboembolism (VTE), with VTE being the second leading cause of morbidity and mortality in these patients. The implementation of lockdowns following the COVID-19 pandemic has resulted in decreased mobility and delayed access to care, thus further increasing the susceptibility to VTE. Cancer patients may also be at a higher risk of SARS-CoV-2 infection and have been shown to be more likely to experience severe COVID-19 disease compared to patients without cancer. Given that both cancer and COVID-19 exhibit a hypercoagulable state, stasis of blood flow, and endothelial injury, cancer patients with COVID-19 constitute a vulnerable population with a high risk of thrombosis and bleeding. However, to date there are limited studies evaluating whether cancer patients infected with SARS-CoV-2 have a higher VTE incidence than COVID-19 patients without cancer, how to assess the risk of VTE, prophylaxis and treatment in this special population. Herein, we highlight the urgent need for studies in cancer patients with COVID-19 to ensure appropriate patient care and improve clinical outcomes.

Conceptualizing a novel Hybrid Decontamination System (HDS) based on UV/H2O2 treatment for the enhanced decontamination and reuse of N95 FFRs.

Environmental challenges (Amsterdam, Netherlands), 5:100276.

The ongoing Pandemic of COVID-19 caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has severely stressed the worldwide healthcare system and has created dangerous shortages of personal protective equipment (PPE) including N95 filtering facepiece respirators (FFRs). Even though suppliers struggled to meet global demand for N95 masks at an unprecedented level, a shortage of FFR appears as a significant factor in the transmission of the disease to frontline workers. CDC, USA has mentioned that FFR decontamination and reuse may be necessary during times of shortage to ensure guaranteed availability. Hence present stressed condition faced by the healthcare sector seeks for an affordable decontamination strategy that can be replicated easily broadening the utility of FFR decontamination across a range of healthcare settings. After reviewing available literature on the various disinfection techniques that may be used for the decontamination of FFRs, a first of its kind, portable Hybrid Decontamination System/procedure has been conceptualized and designed. This system combines the disinfecting properties of both vaporous hydrogen peroxide (VHP) and ultra-violet C irradiation (UV C) to ensure maximum decontamination of N95 respirators. The instrument will be equipped with a hydrogen peroxide chamber and UV light source. Sterilization of the FFRs will be done through treatment with VHP followed by UV light treatment. The proposed system will allow the user to completely sterilize the FFRs in a time-efficient manner.

The "original antigenic sin" and its relevance for SARS-CoV-2 (COVID-19) vaccination.

Clinical immunology communications, 1:13-16.

Imprinting of the specific molecular image of a given protein antigen into immunological memory is one of the hallmarks of immunity. A later contact with a related, but different antigen should not trigger the memory response (because the produced antibodies would not be effective). The preferential expansion of cross-reactive antibodies, or T-lymphocytes for that matter, by a related antigen has been termed the original antigenic sin and was first described by Thomas Francis Jr. in 1960. The phenomenon was initially described for influenza virus, but also has been found for dengue and rotavirus. The antibody dependent enhancement observed in feline coronavirus vaccination also may be related to the original antigenic sin. For a full interpretation of the effectivity of the immune response against SARS-CoV-2, as well as for the success of vaccination, the role of existing immunological memory against circulating corona viruses is reviewed and analyzed.

Current research in behavioral sciences, 2:100011.

BACKGROUND: The coronavirus pandemic appeared as the worst global health disaster of the century. Since the advent of the Second world war-2, humankind has experienced the most challenging health emergencies. The novel respiratory disease (SARS-CoV-2) emerged in Wuhan at the end of December 2019.

AIM: The study focuses on providing education through the educational system with a mode of delivery using digital solutions with a new paradigm method.

METHOD: This research incorporates the statistical data related to the Pakistani Ministry of Health's coronavirus epidemic to draw the results.

RESULTS: WHO reported more than 51.949 million confirmed COVID-19 patients in more than 200 territories and countries. This epidemic caused more than 1.282 million deaths; however, more than 36.49 million people have recovered from the infection of the deadly disease COVID-19, as of November 11, 2020. The COVID-19 has put forward unique challenges in personal and social life spheres. The precautionary measures, including social distancing, called for abrupt closure of educational institutions, leaving the digital solutions as the primary mean of continuity in educational activities.

CONCLUSION: The current review looks into the dynamics of embracing the change in the educational system, ranging from delivery mode to shifting to a new paradigm moving to digital solutions. This study looks into the challenges, issues, barriers, and success parameters of Pakistan's online learning management system. From the preparedness phase to the actual implementation of the learning system at higher education, the level is noteworthy. The private sector has provided higher, secondary, and primary levels; the private sector came forward to maintain learning continuity. The review suggests a way forward ahead for the educational system's continuity and sustainability in the coronavirus pandemic and educational institutions' crises.

Use of 3D printed connectors to redesign full face snorkeling masks in the COVID-19 era: A preliminary technical case-study.

Annals of 3D printed medicine, 3:100023.

The COVID-19 pandemic resulted in severe shortages of personal protection equipment and non-invasive ventilation devices. As traditional supply chains could not meet up with the demand, makeshift solutions were developed and locally manufactured by rapid prototyping networks. Among the different global initiatives, retrofitting of full-face snorkeling masks for Non-Invasive-Ventilation (NIV) applications seems the most challenging. This article provides a systematic overview of rapid prototyped - 3D printed - designs that enable attachment of medical equipment to snorkeling masks, highlighting potential and challenges in additive manufacturing. The different NIV connector designs are compared on low-cost 3D fabrication time and costs, which allows a rapid assessment of developed connectors for health care workers in urgent need of retrofitting snorkeling masks for NIV purposes. Challenges and safety issues of the rapid prototyping approach for healthcare applications during the pandemic are discussed as well. When critical parameters such as the final product cost, geographical availability of the feedstock and the 3D printers and the medical efficiency of the rapid prototyped products are well considered before deploying decentralized 3D printing as manufacturing method, this rapid prototyping strategy contributed to reduce personal protective equipment and NIV shortages during the first wave of the COVID-19 pandemic. It is also concluded that it is crucial to carefully optimize material and printer parameter settings to realize best fitting and airtight connector-mask connections, which is heavily depending on the chosen feedstock and type of printer.

Consent in covid: A researcher's dilemma.

Trends in anaesthesia & critical care, 38:10-12.

An informed consent is a vital component of health care and forms an important component of any research study. Informed consent is the process where a health care provider educates a patient about the risks, benefits, and alternatives of a given procedure or intervention. A proper consent is imperative to ensure safety of the patients. However, obtaining a consent in the hospital settings has become a matter of concern in the times of this coronavirus-19 (COVID-19) pandemic. This brief review describes the additional complexities added to the consent for research and the various modifications needed in view of this pandemic. The current consent proformas need to be modified and individualised to the patient ensuring patient safety during research in the ongoing pandemic. We need to become more familiar with the technology and electronic tools as the acceptable alternative tools of communication in the current scenario. There is a need to incorporate a separate covid consent with due consideration to deferred consent, pre-emptive consent or waiver of a consent.

Printing in a Pandemic: 3D printing solutions for healthcare during COVID-19. A Protocol for a PRISMA systematic review.

Annals of 3D printed medicine, 2:100015.

INTRODUCTION: The COVID-19 pandemic had an unprecedented global socioeconomic impact. Responses to pandemics include strategies to accumulate vast stockpiles of vital medical equipment. In such times of desperation, 3D-printing could be a life-saving alternative.

METHODS: We undertook a PRISMA systematic review of 3D printing solutions in response to COVID-19 utilising the PICO methodology. The objectives were to identify the uses of 3D printing during the COVID-19 pandemic, determine the extent of preclinical testing, comparison to commercial alternatives, presence of regulatory approvals and replicability regarding the description of the printing parameters and the availability of the print file.

RESULTS: Literature searches of MEDLINE (OVID interface)/ PubMed identified 601 studies. Of these, 10 studies fulfilled the inclusion and exclusion criteria. Reported uses of 3D printing included personal protective equipment (PPE), nasopharyngeal swabs and adjunctive anaesthetic equipment. Few studies undertook formal safety and efficacy testing before clinical use with only one study comparing to the commercial equivalent. Six articles made their model print files available for wider use.

CONCLUSION: We describe a protocol for a systematic review of 3D-printed healthcare solutions in response to COVID-19. This remains a viable method of producing vital healthcare equipment when supply chains are exhausted. We hope that this will serve as a summary of innovative 3D-printed solutions during the peak of the pandemic and also highlight concerns and omissions regarding safety and efficacy testing that should be addressed urgently in preparation for a subsequent resurgences and future pandemics.

Environmental challenges induced by extensive use of face masks during COVID-19: A review and potential solutions.

Environmental challenges (Amsterdam, Netherlands), 3:100039.

The ongoing COVID-19 disease significantly affects not only human health, it also affects the wealth of country' economy and everyday routine of human life. To control the spread of the virus, face mask is used as primary personal protective equipment (PPE). Thus, the production and usage of face masks significantly increase as the COVID-19 pandemic still escalating. Further, most of these masks contain plastics or other derivatives of plastics. Therefore, this extensive usage of face masks generates million tons of plastic wastes to the environments in a short span of time. This study aims to investigate the environmental impact induced by face mask wastes and sustainable solution to reduce this waste. An online survey was carried out to identify the types of face mask and number of masks used per week by an individual from 1033 people. Based on this survey and available literature, this study quantifies the amount of plastics waste generated by face masks. However, this survey was limited with certain ages, country and durations (July-August 2020). Thus, the prediction of plastic waste generation, only provide fundamental knowledge about the mask wastes. Results revealed that there is a huge plastic waste remained in land and marine environment in the form of mask waste, which will contribute to micro-plastic pollution. Therefore, this paper also highlights the sustainable approach to the mask production by integrating the use of natural plant fiber in the woven face mask technology to reduce the plastic waste induced by masks. Further, upcycling the mask waste and producing construction materials also discussed.

Nitric oxide and viral infection: Recent developments in antiviral therapies and platforms.

Applied materials today, 22:100887.

Nitric oxide (NO) is a gasotransmitter of great significance to developing the innate immune response to many bacterial and viral infections, while also modulating vascular physiology. The generation of NO from the upregulation of endogenous nitric oxide synthases serves as an efficacious method for inhibiting viral replication in host defense and warrants investigation for the development of antiviral therapeutics. With increased incidence of global pandemics concerning several respiratory-based viral infections, it is necessary to develop broad therapeutic platforms for inhibiting viral replication and enabling more efficient host clearance, as well as to fabricate new materials for deterring viral transmission from medical devices. Recent developments in creating stabilized NO donor compounds and their incorporation into macromolecular scaffolds and polymeric substrates has created a new paradigm for developing NO-based therapeutics for long-term NO release in applications for bactericidal and blood-contacting surfaces. Despite this abundance of research, there has been little consideration of NO-releasing scaffolds and substrates for reducing passive transmission of viral infections or for treating several respiratory viral infections. The aim of this review is to highlight the recent advances in developing gaseous NO, NO prodrugs, and NO donor compounds for antiviral therapies; discuss the limitations of NO as an antiviral agent; and outline future prospects for guiding materials design of a next generation of NO-releasing antiviral platforms.

Obesity is a chronic disease that leads to an increased risk of mortality and morbidity, and the impact of the COVID-19 pandemic may create a new health challenge. There is clear evidence showing that some biological and social factors associated with obesity involve an increased risk of COVID-19 infection, hospitalization, and greater severity compared to people with normal weight. Undoubtedly, obesity involves a low-grade proinflammatory state that produces a dysregulation of the immune system that compromises its ability to respond to respiratory infection by COVID-19 and so produces a worsening of the disease. In this review, the main epidemiological and pathophysiological data that associate obesity with COVID-19 are described.

An Intensive Care Unit (ICU) is an organized system for the provision of care to critically ill patients that provides intensive and specialized medical and nursing care, an enhanced capacity for monitoring, and multiple modalities of physiologic organ support to sustain life during a period of life-threatening organ system insufficiency. While this availability of trained manpower and specialized equipment makes it possible to care for critically ill patients, it also presents singular challenges in the form of man and material management, design concerns, budgetary concerns, and protocolization of treatment. Consequently, the establishment of an ICU requires rigorous design and planning, a process that can take months to years. However, the Coronavirus disease-19 (COVID-19) epidemic has required the significant capacity building to accommodate the increased number of critically ill patients. At the peak of the pandemic, many countries were forced to resort to the building of temporary structures to house critically ill patients, to help tide over the crisis. This narrative review describes the challenges and lessons learned while establishing a 250 bedded ICU in a temporary structure and achieving functionality within a period of a fortnight.

Effect of awake prone positioning in COVID-19 patients- A systematic review.

Trends in anaesthesia & critical care, 36:17-22.

BACKGROUND: Prone positioning is known to reduce mortality in intubated non-COVID-19 patients suffering from moderate to severe acute respiratory distress syndrome (ARDS). However, studies highlighting the effect of awake proning in COVID-19 patients are lacking. We aim to conduct a systematic review of the available literature to highlight the effect of awake proning on the need for intubation, improvement in oxygenation and mortality rates in COVID-19 patients with ARDS.

METHOD: - A systematic search of 2 medical databases (PubMed, Google Scholar) was performed until July 5, 2020. Thirteen studies fulfilled the inclusion criteria, and 210 patients were included for the final analysis.

RESULT: -Majority of the patients were above 50 years of age with a male gender predominance (69%). Face mask (26%) was the most common interface used for oxygen therapy. The intubation and mortality rates were 23.80% (50/210) and 5.41% (5/203) respectively. Awake proning resulted in improvement in oxygenation (reported by 11/13 studies): improvement in SpO2, P/F ratio, PO2 and SaO2 reported by 7/13 (54%), 5/13 (38%), 2/13 (15%) and 1/13 (8%) of the studies. No major complications associated with prone positioning were reported by the included studies.

CONCLUSION: Awake prone positioning demonstrated an improvement in oxygenation of the patients suffering from COVID-19 related respiratory disease. Need for intubation was observed in less than 30% of the patients. Thus, we recommend early and frequent proning in patients suffering from COVID-19 associated ARDS, however, randomized controlled trials are needed before any definite conclusions are drawn.

Insights into neurological dysfunction of critically ill COVID-19 patients.

Trends in anaesthesia & critical care, 36:30-38.

Novel coronavirus spread rapidly around the world infecting millions of people. It was thus declared a pandemic. This new virus damages the lungs. In the most severe cases, it leads to acute respiratory failure that requires intensive care treatment. However, many clinical reports have listed different neurological symptoms, leading to increased interest in the neurological involvement of COVID-19. Various pathophysiological mechanisms have been proposed to explain these neurological aspects. Direct viral invasion of the nervous system, systemic cytokine storm and severe hypoxemia are key factors in the development of symptoms. Critically ill patients present several additional risk factors for nervous system damage. Reasons for these include deep sedation and extended muscular paralysis, bed rest for several days, and the inability to receive proper physical rehabilitation. After ICU treatment, COVID-19 patients generally require an extensive rehabilitation program. However, distancing restrictions mean that in many cases physiotherapists are unable to enter ICUs, delaying the process of rehabilitation.

Speech intelligibility in respiratory protective equipment - Implications for verbal communication in critical care.

Trends in anaesthesia & critical care, 36:23-29.

Respiratory protective equipment (RPE) such as filtering facepiece respirators, elastomeric respirators and powered air-purifying respirators are routinely worn in the critical care unit as a component of personal protective equipment (PPE) when caring for patients with coronavirus disease 2019 (COVID-19). It is the authors' anecdotal experience that RPE may, however, inadvertently interfere with verbal communication between critical care staff. The literature pertaining to the effects of RPE wear on verbal communication was therefore reviewed. A literature search returned 98 articles, and 4 records were identified from other sources; after screening for content relevancy, 15 experimental studies were included in the narrative synthesis. Previous studies in both healthcare and other occupational settings suggest a detrimental impact on speech intelligibility, varying according to RPE type and test conditions. The effects of background noise and potential for increased cognitive load through compensatory behaviours are also identified. The clinical significance of these effects remains uncertain though, as evidence measuring clinical outcomes or errors is lacking. Mitigating strategies include increasing speech intelligibility through environmental changes and technology; modifying verbal communication strategies; and decreasing reliance on verbal communication where possible.

Use of Conventional Chest Imaging and Artificial Intelligence in COVID-19 Infection. A Review of the Literature.

Open respiratory archives, 3(1):100078 pii:S2659-6636(20)30090-4.

The coronavirus disease caused by SARS-Cov-2 is a pandemic with millions of confirmed cases around the world and a high death toll. Currently, the real-time polymerase chain reaction (RT-PCR) is the standard diagnostic method for determining COVID-19 infection. Various failures in the detection of the disease by means of laboratory samples have raised certain doubts about the characterisation of the infection and the spread of contacts. In clinical practice, chest radiography (RT) and chest computed tomography (CT) are extremely helpful and have been widely used in the detection and diagnosis of COVID-19. RT is the most common and widely available diagnostic imaging technique, however, its reading by less qualified personnel, in many cases with work overload, causes a high number of errors to be committed. Chest CT can be used for triage, diagnosis, assessment of severity, progression, and response to treatment. Currently, artificial intelligence (AI) algorithms have shown promise in image classification, showing that they can reduce diagnostic errors by at least matching the diagnostic performance of radiologists. This review shows how AI applied to thoracic radiology speeds up and improves diagnosis, allowing to optimise the workflow of radiologists. It can provide an objective evaluation and achieve a reduction in subjectivity and variability. AI can also help to optimise the resources and increase the efficiency in the management of COVID-19 infection.

Graphene-based field-effect transistor biosensors for the rapid detection and analysis of viruses: A perspective in view of COVID-19.

Carbon trends, 2:100011.

Current situation of COVID-19 demands a rapid, reliable, cost-effective, facile detection strategy to break the transmission chain and biosensor has emerged as a feasible solution for this purpose. Introduction of nanomaterials has undoubtedly improved the performance of biosensor and the addition of graphene enhanced the sensing ability to a peerless level. Amongst different graphene-based biosensing schemes, graphene field-effect transistor marked its unique presence owing to its ability of ultrasensitive and low-noise detection thereby facilitating instantaneous measurements even in the presence of small amounts of analytes. Recently, graphene field-effect transistor type biosensor is even successfully employed in rapid detection of SARS-CoV-2 and this triggers the interest of the scientific community in reviewing the current developments in graphene field-effect transistor. Subsequently, in this article, the recent progress in graphene field-effect transistor type biosensors for the detection of the virus is reviewed and challenges along with their strengths are discussed.

Nanoparticles as delivery vehicles for antiviral therapeutic drugs.

Engineered regeneration, 2:31-46.

With the ongoing COVID-19 pandemic still escalating, many researchers are turning to nanotechnology as a method of treatment not only for this pandemic, but in preparation for the pandemics of the future. Given both a wide variety of biomaterials at their disposal and the recent rise of nanotechnology, scientists now have the means to release and distribute therapeutic drugs in a variety of ways. Such a variety permits medical professionals the ability to choose biomaterials and methods that would provide the best release and treatment methodologies for the viral ailment they are attempting to remedy. This integrative review discusses context of previous pandemics, viral pathogenesis, issues associated with the current state of antiviral delivery systems, numerous biomaterials used for this purpose, and further information regarding the ongoing global COVID-19 pandemic.

The role of wastewater treatment plants as tools for SARS-CoV-2 early detection and removal.

Journal of water process engineering, 38:101544.

The world is facing the third coronavirus caused pandemic in less than twenty years. The SARS-CoV-2 virus not only affects the human respiratory system, but also the gastrointestinal tract. The virus has been found in human feces, in sewage and in wastewater treatment plants. It has the potential to become a panzootic disease, as it is now proven that several mammalian species become infected. Since it has been shown that the virus can be detected in sewage even before the onset of symptoms in the local population, Wastewater Based Epidemiology should be developed not only to localize infection clusters of the primary wave but also to detect a potential second, or subsequent, wave. To prevent a panzootic, virus removal techniques from wastewater need to be implemented to prevent the virus dissemination into the environment. In that context, this review presents recent improvements in all the fields of wastewater treatment from treatment ponds to the use of algae or nanomaterials with a particular emphasis on membrane-based techniques.

Neurologia (Barcelona, Spain), 35(9):646-654.

INTRODUCTION: Numerous cases have been reported of patients with symptoms of Guillain-Barré syndrome associated with COVID-19, but much information is still lacking on this association and its implications. The objective of this review is to analyse the available evidence on this topic in the adult population.

MATERIAL AND METHODS: A systematic review was conducted of studies published on scientific databases: PubMed, Cochrane, Science Direct, Medline, and WHO COVID-19 database.

RESULTS: We identified 47 studies, which were analysed and completed using the Covidence platform; the final analysis included 24 articles, with a total of 30 patients.

CONCLUSIONS: We found a strong association between both conditions; furthermore, the studies analysed highlight differences in the presentation of the disease, with greater severity of symptoms in Guillain-Barre syndrome associated with COVID-19.

Acta otorrinolaringologica espanola, 71(6):367-378.

The appearance of a new coronavirus disease called COVID-19 at the end of 2019 and its pandemic expansion in the world has changed the usual practice of the specialty of Otorhinolaryngology (ENT). After a phase of exponential growth of infections, it has been possible to enter a phase of control of the spread of the disease in which the possibility of infection persists, and the appearance of new cases is considered acceptable by the health system.The aim of this document is to review the available evidence and propose strategies and recommendations for the medical-surgical practice of otorhinolaryngology and head and neck surgery, which allow establishing the usual activity, adapting the safety and efficacy standards to the current situation. Therefore, it is required to identify and classify patients according to criteria of infectious-immunological status, and to establish recommendations for protection in consultations, hospitalization and the operating room, which avoid the transmission of the disease to other users and healthcare personnel, in the specific context of the development of our specialty. This document is the result of the collaboration of all the scientific commissions and the SEORLCCC COVID-19 committee.

[Olfactory dysfunction in COVID-19, a review of the evidence and implications for pandemic management].

Acta otorrinolaringologica espanola, 71(6):379-385.

There is debate as to whether olfactory dysfunction should be considered a symptom of COVID-19 infection. We undertook a systematic literature review of the articles indexed in PubMed on olfactory disorders in viral respiratory tract conditions, with special emphasis on COVID-19. The main objective was to find evidence of clinical interest to support the relationship between anosmia and COVID-19. Olfactory disorders in upper respiratory tract infections are frequent, most caused by obstruction due to oedema of the nasal mucosa. Occasionally, post-viral sensorineural olfactory dysfunction occurs, with a variable prognosis. The evidence on anosmia in COVID-19 patients is extremely limited, corresponding to a level 5 or D of the Centre for Evidence-Based Medicine. According to the available evidence, it seems reasonable to apply isolation, hygiene and social distancing measures in patients with recent olfactory disorders as the only symptom, although the usefulness of diagnostic tests for this type of patient should be studied.

Is the prone position indicated in critically ill patients with SARS-CoV-2 during the peri-operative period?.

Trends in anaesthesia & critical care, 34:38-41.

Coronaviruses including SARS-CoV-2 are a large family of viruses that cause illnesses ranging from the common cold to more severe diseases. A SARS-CoV-2 is a new strain that has not been previously identified in humans. The majority of critically ill patients admitted to intensive care units with confirmed severe infection with SARS-CoV-2 developed an acute respiratory distress like syndrome. The main objective of this opinion paper is to raise the discussion about the possible benefit of keeping the patient with COVID-19 disease and acute hypoxemic respiratory failure (AHRF) in the prone position during the perioperative period, especially where this position is not a required factor for the surgical or invasive procedure. We believe that the prone position, due to its favorable pulmonary physiology, can improve the V̇/Q̇ ratio in the perioperative period.

Emerging patterns of hypercoagulability associated with critical COVID-19: A review.

Trends in anaesthesia & critical care, 34:4-13.

While the COVID-19 pandemic sweeps the world, much evidence is being gathered regarding its novel pathological mechanisms. It is the authors' clinical experience that patients in the intensive care unit suffering from COVID-19 are extremely pro-coagulable, with venous and arterial thromboembolism frequently observed, and losses of vascular access lines and filtration circuits to thrombosis now commonplace. Here, we explore the evidence for hypercoagulability in this group, presenting evidence of both a localised pulmonary hypercoagulability, and a systemic hypercoagulability resulting in thrombosis distant to the pulmonary vasculature. Furthermore, we discuss the possible risk factors exacerbated by, or selected for in COVID-19. We review the available evidence for use of plasma D-dimer as a prognostic marker, exploring the possibility that it acts as a marker of a COVID-19-associated hypercoagulability. We review the evidence for a pro-coagulant subtype of disseminated intravascular coagulation, discussing its clinical significance. Finally, we discuss the current evidence surrounding treatment of COVID-19 hypercoagulability, including prophylactic and treatment-dose heparin, thrombolytic agents, antiplatelet agents, and direct thrombin inhibitors, among others. We suggest areas in which further investigation is urgently needed to reduce the startling incidence of thrombosis in this group, a complication no doubt contributing to morbidity and mortality.

The COVID-19 pandemic caused by the SARS-CoV-2 virus has caused tens of thousands of deaths in Spain and has managed to breakdown the healthcare system hospitals in the Community of Madrid, largely due to its tendency to cause severe pneumonia, requiring ventilatory support. This fact has caused our center to collapse, with 130% of its beds occupied by COVID-19 patients, thus causing the absolute cessation of activity of the urology service, the practical disappearance of resident training programs, and the incorporation of a good part of the urology staff into the group of medical personnel attending these patients. In order to recover from this extraordinary level of suspended activity, we will be obliged to prioritize pathologies based on purely clinical criteria, for which tables including the relevance of each pathology within each area of urology are being proposed. Technology tools such as online training courses or surgical simulators may be convenient for the necessary reestablishment of resident education.

Open respiratory archives, 2(3):179-185.

The state of alarm declared by the Spanish government as the main measure for preventing contagion has involved a change in the clinical management of chronic patients. Although new communication technologies offer us many ways to establish direct but remote contact, the peculiarities of the COPD patient often mean that their healthcare is reduced to telephone calls. The challenge of caring for COPD patients is made even more complex when it has to be delivered over the phone. The interview must be conducted without examining the patient, without performing additional tests, and without checking their inhalation technique. Therefore, healthcare providers who conduct these interviews must be trained to perform them properly in order to make the right decisions. This document is aimed at healthcare professionals who need to provide some form of telephone care to COPD patients during the SARS-CoV-2 pandemic and is based on the authors' experience in telephone interviews conducted during this period. It summarizes essential aspects of how this interview should be approached, how to conduct it, what factors should be kept in mind, how to organize the interview, and how to keep patients informed. It is very likely that from now on this type of interview will be common practice in the care of our patients, so we need to learn how to structure a new model of healthcare for many of the clinical visits that have until now been conducted face-to-face.

Prevention and control strategies of general surgeons under COVID-19 pandemic.

Surgery in practice and science, 1:100008.

The novel coronavirus SARS-CoV-2 and the disease caused by it, COVID-19, have spread to virtually all countries worldwide within just a few months. The economic and sanitary impact has been enormous. In March 2020, the World Health Organization declared COVID-19 a pandemic. How to effectively prevent and control SARS-CoV-2 transmission while providing care to surgical patients during the pandemic is a crucial topic. In order to minimize the risk of cross-infection between patients and physicians, many hospitals have taken measures to limit outpatient services, elective hospitalizations, and the number of operations. Based on the prevention and control measures stipulated by major medical institutions in China, this overview provides recommendations for surgeons from three aspects: outpatient treatment, ward management and perioperative protection. Telemedicine should be encouraged as a means of social distancing. Outpatient examination should be selected. Reasonable spatial arrangement and effective environmental disinfection are important for ward management. Patient selection for surgery and timing of operations should be carefully discussed within multi-disciplinary teams. Appropriate personal protective equipment should be worn adapted to the situational risk. On December 31, 2019, China reported to the WHO Country Office a pneumonia of unknown cause detected in Wuhan [1], [3]. Subsequently, the disease later named COVID-19 affected a substantial proportion of the population in Wuhan and spread to other areas of China. Relying on a nationwide shutdown and mandatory quarantine, China has effectively curtailed the domestic outbreak. However, due to the high transmissibility of SARS-Cov-2 and the mobility of people, COVID-19 spread to the rest of the world. Many hospitals worldwide were faced with confirmed and suspected SARS-Cov-2 infections, putting a huge strain on the safety of patients and employees. Consequently, surgical patients who seek medical care during the COVID-19 pandemic present significant challenges. This paper summarizes medical care and infection prevention and control in general surgery patients during the COVID-19, pandemic in the light of the current situation in China. It provides reference for surgeons and decision makers in health care in other countries suffering from the COVID-19 pandemic.

Inhibitory effect of food-functioned phytochemicals on dysregulated inflammatory pathways triggered by SARS-CoV-2: a mechanistic review.

Critical reviews in food science and nutrition [Epub ahead of print].

Inflammatory cascades of the dysregulated inflammatory pathways in COVID-19 can cause excessive production of pro-inflammatory cytokines and chemokines leading to cytokine storm syndrome (CSS). The molecular cascades involved in the pathways may be targeted for discovery of new anti-inflammatory agents. Many plant extracts have been used clinically in the management of COVID-19, however, their immunosuppressive activities were mainly investigated based on in silico activity. Dietary flavonoids of the extracts such as quercetin, luteolin, kaempferol, naringenin, isorhamnetin, baicalein, wogonin, and rutin were commonly identified as responsible for their inhibitory effects. The present review critically analyzes the anti-inflammatory effects and mechanisms of phytochemicals, including dietary compounds against cytokine storm (CS) and hyperinflammation via inhibition of the altered inflammatory pathways triggered by SARS-CoV-2, published since the emergence of COVID-19 in December 2019. Only a few phytochemicals, mainly dietary compounds such as nanocurcumin, melatonin, quercetin, 6-shagoal, kaempferol, resveratrol, andrographolide, and colchicine have been investigated either in in silico or preliminary clinical studies to evaluate their anti-inflammatory effects against COVID-19. Sufficient pre-clinical studies on safety and efficacy of anti-inflammatory effects of the phytochemicals must be performed prior to proper clinical studies to develop them into therapeutic adjuvants in the prevention and treatmemt of COVID-19 symptoms.

Seasonal influenza vaccine performance and the potential benefits of mRNA vaccines.

Human vaccines & immunotherapeutics, 20(1):2336357.

Influenza remains a public health threat, partly due to suboptimal effectiveness of vaccines. One factor impacting vaccine effectiveness is strain mismatch, occurring when vaccines no longer match circulating strains due to antigenic drift or the incorporation of inadvertent (eg, egg-adaptive) mutations during vaccine manufacturing. In this review, we summarize the evidence for antigenic drift of circulating viruses and/or egg-adaptive mutations occurring in vaccine strains during the 2011-2020 influenza seasons. Evidence suggests that antigenic drift led to vaccine mismatch during four seasons and that egg-adaptive mutations caused vaccine mismatch during six seasons. These findings highlight the need for alternative vaccine development platforms. Recently, vaccines based on mRNA technology have demonstrated efficacy against SARS-CoV-2 and respiratory syncytial virus and are under clinical evaluation for seasonal influenza. We discuss the potential for mRNA vaccines to address strain mismatch, as well as new multi-component strategies using the mRNA platform to improve vaccine effectiveness.

Effect of Surfactant Therapy on Clinical Outcomes of COVID-19 Patients With ARDS: A Systematic Review and Meta-Analysis.

Cureus, 16(3):e56238.

INTRODUCTION: The COVID-19 pandemic has brought unprecedented challenges, not only in terms of public health but also in the realm of innovative therapeutic approaches to combat the severe respiratory complications associated with the virus. The effect of surfactant therapy on reducing mortality in COVID-19 patients with acute respiratory distress syndrome (ARDS) hasn't been explored before.

METHODS: We conducted a search on PubMed, Scopus, Science Direct, and Clinicaltrials.gov to identify relevant studies, incorporating subject headings and keywords related to "Surfactant Therapy," "COVID-19," and "ARDS." Binary random effects were used to estimate the odds ratio (OR) for 28-day mortality, and continuous random effects were used to estimate the mean difference (MD) for length of hospitalization with their respective 95% confidence interval (CI). Analysis was performed with RevMan Version 5.4.1 (The Cochrane Collaboration, London, GBR).

RESULTS: We included four studies with 126 patients. Patients who received surfactant had lower odds of mortality (OR 0.53, 95% CI (0.23, 1.20), p=0.13) and a shorter duration of hospital stay (MD -5.69, 95% CI [-7.06, -4.30], p <0.00001) compared to patients who did not receive surfactant therapy. However, the findings regarding mortality were not statistically significant.

CONCLUSIONS: The COVID-19 patients with ARDS who received surfactant therapy had lower hospitalization stays and mortality rates, indicating that surfactant therapy may improve clinical outcomes in COVID-19 patients with ARDS. However, the results were not significant, and further research with more prospective studies and randomized clinical trials (RCTs) with larger sample sizes is needed to confirm these findings and assess their practical significance and generalizability.

Potential strategies for supporting mental health and mitigating the risk of burnout among healthcare professionals: insights from the COVID-19 pandemic.

EClinicalMedicine, 71:102562.

Healthcare professionals (HCPs) experienced prolonged stressful conditions during the coronavirus disease 2019 pandemic, and the global situation (particularly in the United Kingdom) meant that they continue to sustain mental stress related to the subsequent cost-of-living and healthcare budgeting crises. The psychological toll on HCPs may lead to increased staff attrition, adversely impacting the quality of patient care and work security. To help mitigate this psychological impact, the current evidence is strongly supportive of healthcare providers consistently adopting programmes fostering improvement in coping and resilience, facilitating healthy lifestyle, and allocating some resources for therapeutic strategies (e.g. cognitive behavioural therapy-based strategies and other strategies specified to trauma-related issues) which can be delivered by trained professionals. We stress that some approaches are not a one-size-fits-all strategy, and we also highlight the need to encourage treatment-seeking among those who need it. These strategies are highly relevant to healthcare employers and policymakers to support all HCPs in settings marked by prolonged periods of stress. The investment in these strategies are expected not only to reduce staff attrition in the long-term, but are likely to add to the cost-effectiveness of overall healthcare budgetary allocation.

Therapeutic development targeting host heparan sulfate proteoglycan in SARS-CoV-2 infection.

Frontiers in medicine, 11:1364657.

The global pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has led to an urgent need for effective therapeutic options. SARS-CoV-2 is a novel coronavirus responsible for the COVID-19 pandemic that has resulted in significant morbidity and mortality worldwide. The virus is known to enter host cells by binding to the angiotensin-converting enzyme 2 (ACE2) receptor, and emerging evidence suggests that heparan sulfate proteoglycans (HSPGs) play a crucial role in facilitating this process. HSPGs are abundant cell surface proteoglycan present in many tissues, including the lung, and have been shown to interact directly with the spike protein of SARS-CoV-2. This review aims to summarize the current understanding of the role of HSPGs in SARS-CoV-2 infection and the potential of developing new therapies targeting HSPGs.

A review on Gaucher disease: therapeutic potential of β-glucocerebrosidase-targeted mRNA/saRNA approach.

International journal of biological sciences, 20(6):2111-2129.

Gaucher disease (GD), a rare hereditary lysosomal storage disorder, occurs due to a deficiency in the enzyme β-glucocerebrosidase (GCase). This deficiency leads to the buildup of substrate glucosylceramide (GlcCer) in macrophages, eventually resulting in various complications. Among its three types, GD2 is particularly severe with neurological involvements. Current treatments, such as enzyme replacement therapy (ERT), are not effective for GD2 and GD3 due to their inability to cross the blood-brain barrier (BBB). Other treatment approaches, such as gene or chaperone therapies are still in experimental stages. Additionally, GD treatments are costly and can have certain side effects. The successful use of messenger RNA (mRNA)-based vaccines for COVID-19 in 2020 has sparked interest in nucleic acid-based therapies. Remarkably, mRNA technology also offers a novel approach for protein replacement purposes. Additionally, self-amplifying RNA (saRNA) technology shows promise, potentially producing more protein at lower doses. This review aims to explore the potential of a cost-effective mRNA/saRNA-based approach for GD therapy. The use of GCase-mRNA/saRNA as a protein replacement therapy could offer a new and promising direction for improving the quality of life and extending the lifespan of individuals with GD.

Covid-19 pandemic? Mental health implications among nurses and Proposed interventions.

AIMS public health, 11(1):273-293.

BACKGROUND: With its abrupt and huge health and socio-economic consequences, the coronavirus disease (COVID-19) pandemic has led to a uniquely demanding, intensely stressful, and even traumatic period. Healthcare workers (HCW), especially nurses, were exposed to mental health challenges during those challenging times.

OBJECTIVES: Review the current literature on mental health problems among nurses caring for COVID-19 patients.

METHODS: This is a narrative review and critical evaluation of relevant publications.

RESULTS: Nurses experienced higher levels of stress, burnout, anxiety, depression, frustration, stigma, and depersonalization compared to other HCW. Factors that increased this symptomatology included concerns about infection or infection of family members, inadequate staff protective equipment, extended working hours, insufficient information, a reduced sense of security, and post-traumatic stress disorder. The factors that improved the psychopathology included a general positive attitude, job satisfaction, adequate information and education, harmonious group relationships, post-traumatic development, emotional intelligence, psychological counseling, mindfulness-based stress reduction, stable leadership, guidance, and moral and practical administrative support.

CONCLUSIONS: Recent studies clearly show that nurses, especially women, are the most vulnerable subgroup among HCW and are particularly prone to mental health impacts during the COVID-19 pandemic. The documented mental health vulnerability of frontline nursing staff during the COVID-19 pandemic requires preventive nursing management actions to increase resilience and to develop relevant defense mechanisms.

Residents and Fellows of US Medical Residencies and Fellowships Strongly Prefer In-Person to Virtual Conference Format: A Cross-sectional Survey.

JB & JS open access, 9(2):.

INTRODUCTION: Medical conferences are an integral aspect of medical education as they allow attendees to stay up to date with recent advancements in medicine, to develop presentation and communication skills, and to network and establish connections with professionals in their field of interest. But, when the coronavirus disease 2019 (COVID-19) pandemic was declared in March 2020, face-to-face medical conferences were suspended, and conference organizers began shifting their meetings to virtual platforms. These new virtual conferences afforded medical residents and fellows the unique opportunity to attend conferences from the comfort of their own home or workplace; however, the virtual meeting platforms did not provide attendees with the same networking experiences as in-person conferences. Since the end of the COVID-19 public health emergency, medical conferences are now faced with the question of whether they should remain virtual, shift back to in-person meetings, or develop a hybrid model of both options. Thus, the purpose of this study was to analyze medical resident and fellow sentiments and preferences by comparing virtual and in-person conference formats.

METHODS: A voluntary electronic survey was distributed to medical residents and fellows across the United States through their program coordinators and directors.

RESULTS: The main findings of this study suggest that medical residents and fellows largely prefer in-person conferences (85%) as compared to a virtual format because of the networking opportunities afforded to them along with the development of camaraderie with their peers. The findings in this study suggest that the largest benefit in attending a virtual conference is the flexibility to attend from any location (79% important or very important), which offered convenience, flexibility, and comfort to participants (n = 100).

CONCLUSION: These results support our hypothesis that despite the convenience and portability afforded by attending conferences virtually, medical residents and fellows still ultimately prefer to attend conferences in person. Overall, the findings in this study are of relevance to conference organizers in understanding the driving forces behind attendance and should be considered in determining meeting format.

Unlocking the potential of nanocarrier-mediated mRNA delivery across diverse biomedical frontiers: A comprehensive review.

International journal of biological macromolecules pii:S0141-8130(24)01944-5 [Epub ahead of print].

Messenger RNA (mRNA) has gained marvelous attention for managing and preventing various conditions like cancer, Alzheimer's, infectious diseases, etc. Due to the quick development and success of the COVID-19 mRNA-based vaccines, mRNA has recently grown in prominence. A lot of products are in clinical trials and some are already FDA-approved. However, still improvements in line of optimizing stability and delivery, reducing immunogenicity, increasing efficiency, expanding therapeutic applications, scalability and manufacturing, and long-term safety monitoring are needed. The delivery of mRNA via a nanocarrier system gives a synergistic outcome for managing chronic and complicated conditions. The modified nanocarrier-loaded mRNA has excellent potential as a therapeutic strategy. This emerging platform covers a wide range of diseases, recently, several clinical studies are ongoing and numerous publications are coming out every year. Still, many unexplained physical, biological, and technical problems of mRNA for safer human consumption. These complications were addressed with various nanocarrier formulations. This review systematically summarizes the solved problems and applications of nanocarrier-based mRNA delivery. The modified nanocarrier mRNA meaningfully improved mRNA stability and abridged its immunogenicity issues. Furthermore, several strategies were discussed that can be an effective solution in the future for managing complicated diseases.

Neuroinvasion and neurotropism of severe acute respiratory syndrome coronavirus 2 infection.

Current opinion in microbiology, 79:102474 pii:S1369-5274(24)00050-X [Epub ahead of print].

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of coronavirus disease 2019, contributes to neurological pathologies in nearly 30% of patients, extending beyond respiratory symptoms. These manifestations encompass disorders of both the peripheral and central nervous systems, causing among others cerebrovascular issues and psychiatric manifestations during the acute and/or post-acute infection phases. Despite ongoing research, uncertainties persist about the precise mechanism the virus uses to infiltrate the central nervous system and the involved entry portals. This review discusses the potential entry routes, including hematogenous and anterograde transport. Furthermore, we explore variations in neurotropism, neurovirulence, and neurological manifestations among pandemic-associated variants of concern. In conclusion, SARS-CoV-2 can infect numerous cells within the peripheral and central nervous system, provoke inflammatory responses, and induce neuropathological changes.

Renal implications of coronavirus disease 2019: insights into viral tropism and clinical outcomes.

Current opinion in microbiology, 79:102475 pii:S1369-5274(24)00051-1 [Epub ahead of print].

In recent years, multiple coronaviruses have emerged, with the latest one, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), causing a global pandemic. Besides respiratory symptoms, some patients experienced extrapulmonary effects, such as cardiac damage or renal injury, indicating the broad tropism of SARS-CoV-2. The ability of the virus to effectively invade the renal cellular environment can eventually cause tissue-specific damage and disease. Indeed, patients with severe coronavirus disease 2019 exhibited a variety of symptoms such as acute proximal tubular injury, ischemic collapse, and severe acute tubular necrosis resulting in irreversible kidney failure. This review summarizes the current knowledge on how it is believed that SARS-CoV-2 influences the renal environment and induces kidney disease, as well as current therapy approaches.

SARS-CoV-2 vaccines and myocarditis.

Clinical medicine (London, England), 23(5):495-502.

The development of safe and effective vaccines against severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) was a major turning point in the fight against the Coronavirus 2019 (COVID-19) pandemic. However, pharmacovigilance has revealed a small but significant incidence of cardiac inflammation manifesting clinically as myocarditis or pericarditis, particularly in younger vaccine recipients. The incidence is the highest among men under age 40 within a week of receiving the second dose of the mRNA vaccine. In this review, we summarise the evidence for, and guidelines in relation to, SARS-CoV2 vaccine-related myocarditis.

The impact of COVID-19 pandemic on gambling: A systematic review.

Addictive behaviors, 155:108037 pii:S0306-4603(24)00086-8 [Epub ahead of print].

BACKGROUND AND AIMS: Since the COVID-19 outbreak, people's habits changed radically. In fact, to limit the spread of SARS-CoV-2, governments implemented restrictive measures that influenced the lives of individuals. The aim of this systematic review is to analyze the impact of COVID-19 on gambling by examining three different outcomes: frequency, expenditure, and transition among possible types of gambling.

METHODS: All studies assessing the impact of restrictive measures implemented to limit the spread of SARS-CoV-2 on gambling were included. For the search, two different databases were used: Pubmed and CINAHL. Moreover, two different populations were analyzed: the general population, and subjects who used to gamble before SARS-CoV-2 pandemic. All qualitative studies, reports not based on peer-review, and papers in which the statistical unit was not the subject but the gambling or wagering operators were excluded.

RESULTS: From the search, 408 reports were identified. Of these, 28 were included in the systematic review. From the studies, a strong reduction in the frequency and expenditure of land-based gambling emerged, while the results about online gambling were different among the studies. However, a reduction was observed assessing sports betting, and an increase emerged considering online casino and skill games. Finally, a significant migration from land-based gambling to online platforms was identified. The main reasons for these findings were the physical closures of land-based gambling venues and the more time spent at home, the suspension or cancelation of sporting events on which subjects used to bet, and more mental health issues during this challenging period.

CONCLUSIONS: The COVID-19 pandemic greatly affected subjects' habits, including gambling, by reducing land-based gambling and sports betting, and increasing gambling on online platforms. This shift poses significant challenges, requiring a comprehensive approach to monitor and mitigate the negative consequences of this increase in online gambling caused by the pandemic.

Curcumin as a natural potential drug candidate against important zoonotic viruses and prions: A narrative review.

Phytotherapy research : PTR [Epub ahead of print].

Zoonotic diseases are major public health concerns and undeniable threats to human health. Among Zoonotic diseases, zoonotic viruses and prions are much more difficult to eradicate, as they result in higher infections and mortality rates. Several investigations have shown curcumin, the active ingredient of turmeric, to have wide spectrum properties such as anti-microbial, anti-vascular, anti-inflammatory, anti-tumor, anti-neoplastic, anti-oxidant, and immune system modulator properties. In the present study, we performed a comprehensive review of existing in silico, in vitro, and in vivo evidence on the antiviral (54 important zoonotic viruses) and anti-prion properties of curcumin and curcuminoids in PubMed, Google Scholar, Science Direct, Scopus, and Web of Science databases. Database searches yielded 13,380 results, out of which 216 studies were eligible according to inclusion criteria. Of 216 studies, 135 (62.5%), 24 (11.1%), and 19 (8.8%) were conducted on the effect of curcumin and curcuminoids against SARS-CoV-2, Influenza A virus, and dengue virus, respectively. This review suggests curcumin and curcuminoids as promising therapeutic agents against a wide range of viral zoonoses by targeting different proteins and signaling pathways.

Neutrophil Extracellular Traps in Cardiovascular and Aortic Disease: A Narrative Review on Molecular Mechanisms and Therapeutic Targeting.

International journal of molecular sciences, 25(7):.

Neutrophil extracellular traps (NETs), composed of DNA, histones, and antimicrobial proteins, are released by neutrophils in response to pathogens but are also recognized for their involvement in a range of pathological processes, including autoimmune diseases, cancer, and cardiovascular diseases. This review explores the intricate roles of NETs in different cardiovascular conditions such as thrombosis, atherosclerosis, myocardial infarction, COVID-19, and particularly in the pathogenesis of abdominal aortic aneurysms. We elucidate the mechanisms underlying NET formation and function, provide a foundational understanding of their biological significance, and highlight the contribution of NETs to inflammation, thrombosis, and tissue remodeling in vascular disease. Therapeutic strategies for preventing NET release are compared with approaches targeting components of formed NETs in cardiovascular disease. Current limitations and potential avenues for clinical translation of anti-NET treatments are discussed.

Smelling TNT: Trends of the Terminal Nerve.

International journal of molecular sciences, 25(7):.

There is very little knowledge regarding the terminal nerve, from its implications in the involvement and pathogenesis of certain conditions, to its embryological origin. With this review, we try to summarize the most important evidence on the terminal nerve, aiming to clarify its anatomy and the various functions attributed to it, to better interpret its potential involvement in pathological processes. Recent studies have also suggested its potential role in the control of human reproductive functions and behaviors. It has been hypothesized that it plays a role in the unconscious perception of specific odors that influence autonomic and reproductive hormonal systems through the hypothalamic-pituitary-gonadal axis. We used the PubMed database and found different articles which were then selected independently by three authors. We found 166 articles, of which, after careful selection, only 21 were analyzed. The terminal nerve was always thought to be unimportant in our body. It was well studied in different types of animals, but few studies have been completed in humans. For this reason, its function remains unknown. Studies suggest a possible implication in olfaction due to the anatomical proximity with the olfactive nerve. Others suggest a more important role in reproduction and sexual behaviors. New emerging information suggests a possible role in Kallmann syndrome and COVID-19.

The Influence of Microglia on Neuroplasticity and Long-Term Cognitive Sequelae in Long COVID: Impacts on Brain Development and Beyond.

International journal of molecular sciences, 25(7):.

Microglial cells, the immune cells of the central nervous system, are key elements regulating brain development and brain health. These cells are fully responsive to stressors, microenvironmental alterations and are actively involved in the construction of neural circuits in children and the ability to undergo full experience-dependent plasticity in adults. Since neuroinflammation is a known key element in the pathogenesis of COVID-19, one might expect the dysregulation of microglial function to severely impact both functional and structural plasticity, leading to the cognitive sequelae that appear in the pathogenesis of Long COVID. Therefore, understanding this complex scenario is mandatory for establishing the possible molecular mechanisms related to these symptoms. In the present review, we will discuss Long COVID and its association with reduced levels of BDNF, altered crosstalk between circulating immune cells and microglia, increased levels of inflammasomes, cytokines and chemokines, as well as the alterations in signaling pathways that impact neural synaptic remodeling and plasticity, such as fractalkines, the complement system, the expression of SIRPα and CD47 molecules and altered matrix remodeling. Together, these complex mechanisms may help us understand consequences of Long COVID for brain development and its association with altered brain plasticity, impacting learning disabilities, neurodevelopmental disorders, as well as cognitive decline in adults.

Possible Role of Cannabis in the Management of Neuroinflammation in Patients with Post-COVID Condition.

International journal of molecular sciences, 25(7):.

The post-COVID condition (PCC) is a pathology stemming from COVID-19, and studying its pathophysiology, diagnosis, and treatment is crucial. Neuroinflammation causes the most common manifestations of this disease including headaches, fatigue, insomnia, depression, anxiety, among others. Currently, there are no specific management proposals; however, given that the inflammatory component involves cytokines and free radicals, these conditions must be treated to reduce the current symptoms and provide neuroprotection to reduce the risk of a long-term neurodegenerative disease. It has been shown that cannabis has compounds with immunomodulatory and antioxidant functions in other pathologies. Therefore, exploring this approach could provide a viable therapeutic option for PCC, which is the purpose of this review. This review involved an exhaustive search in specialized databases including PubMed, PubChem, ProQuest, EBSCO, Scopus, Science Direct, Web of Science, and Clinical Trials. Phytocannabinoids, including cannabidiol (CBD), cannabigerol (CBG), and Delta-9-tetrahydrocannabinol (THC), exhibit significant antioxidative and anti-inflammatory properties and have been shown to be an effective treatment for neuroinflammatory conditions. These compounds could be promising adjuvants for PCC alone or in combination with other antioxidants or therapies. PCC presents significant challenges to neurological health, and neuroinflammation and oxidative stress play central roles in its pathogenesis. Antioxidant therapy and cannabinoid-based approaches represent promising areas of research and treatment for mitigating adverse effects, but further studies are needed.

Beyond Borders of the Cell: How Extracellular Vesicles Shape COVID-19 for People with Cystic Fibrosis.

International journal of molecular sciences, 25(7):.

The interaction between extracellular vesicles (EVs) and SARS-CoV-2, the virus causing COVID-19, especially in people with cystic fibrosis (PwCF) is insufficiently studied. EVs are small membrane-bound particles involved in cell-cell communications in different physiological and pathological conditions, including inflammation and infection. The CF airway cells release EVs that differ from those released by healthy cells and may play an intriguing role in regulating the inflammatory response to SARS-CoV-2. On the one hand, EVs may activate neutrophils and exacerbate inflammation. On the other hand, EVs may block IL-6, a pro-inflammatory cytokine associated with severe COVID-19, and protect PwCF from adverse outcomes. EVs are regulated by TGF-β signaling, essential in different disease states, including COVID-19. Here, we review the knowledge, identify the gaps in understanding, and suggest future research directions to elucidate the role of EVs in PwCF during COVID-19.

Vitamin D Supplementation in Neonatal and Infant MIS-C Following COVID-19 Infection.

International journal of molecular sciences, 25(7):.

To date, the SARS-CoV-2 pandemic still represents a great clinical challenge worldwide, and effective anti-COVID-19 drugs are limited. For this reason, nutritional supplements have been investigated as adjuvant therapeutic approaches in disease management. Among such supplements, vitamin D has gained great interest, due to its immunomodulatory and anti-inflammatory actions both in adult and pediatric populations. Even if there is conflicting evidence about its prevention and/or mitigation effectiveness in SARS-CoV-2 infection, several studies demonstrated a strict correlation between hypovitaminosis D and disease severity in acute COVID-19 and MIS-C (multisystem inflammatory syndrome in children). This narrative review offers a resume of the state of the art about vitamin D's role in immunity and its clinical use in the context of the current pandemic, specially focusing on pediatric manifestations and MIS-C. It seems biologically reasonable that interventions aimed at normalizing circulating vitamin D levels could be beneficial. To help clinicians in establishing the correct prophylaxis and/or supportive therapy with vitamin D, well-designed and adequately statistically powered clinical trials involving both adult and pediatric populations are needed. Moreover, this review will also discuss the few other nutraceuticals evaluated in this context.

The Three-Dimensional Reference Interaction Site Model Approach as a Promising Tool for Studying Hydrated Viruses and Their Complexes with Ligands.

International journal of molecular sciences, 25(7):.

Viruses are the most numerous biological form living in any ecosystem. Viral diseases affect not only people but also representatives of fauna and flora. The latest pandemic has shown how important it is for the scientific community to respond quickly to the challenge, including critically assessing the viral threat and developing appropriate measures to counter this threat. Scientists around the world are making enormous efforts to solve these problems. In silico methods, which allow quite rapid obtention of, in many cases, accurate information in this field, are effective tools for the description of various aspects of virus activity, including virus-host cell interactions, and, thus, can provide a molecular insight into the mechanism of virus functioning. The three-dimensional reference interaction site model (3D-RISM) seems to be one of the most effective and inexpensive methods to compute hydrated viruses, since the method allows us to provide efficient calculations of hydrated viruses, remaining all molecular details of the liquid environment and virus structure. The pandemic challenge has resulted in a fast increase in the number of 3D-RISM calculations devoted to hydrated viruses. To provide readers with a summary of this literature, we present a systematic overview of the 3D-RISM calculations, covering the period since 2010. We discuss various biophysical aspects of the 3D-RISM results and demonstrate capabilities, limitations, achievements, and prospects of the method using examples of viruses such as influenza, hepatitis, and SARS-CoV-2 viruses.

Properties and Mechanisms of Deletions, Insertions, and Substitutions in the Evolutionary History of SARS-CoV-2.

International journal of molecular sciences, 25(7):.

SARS-CoV-2 has accumulated many mutations since its emergence in late 2019. Nucleotide substitutions leading to amino acid replacements constitute the primary material for natural selection. Insertions, deletions, and substitutions appear to be critical for coronavirus's macro- and microevolution. Understanding the molecular mechanisms of mutations in the mutational hotspots (positions, loci with recurrent mutations, and nucleotide context) is important for disentangling roles of mutagenesis and selection. In the SARS-CoV-2 genome, deletions and insertions are frequently associated with repetitive sequences, whereas C>U substitutions are often surrounded by nucleotides resembling the APOBEC mutable motifs. We describe various approaches to mutation spectra analyses, including the context features of RNAs that are likely to be involved in the generation of recurrent mutations. We also discuss the interplay between mutations and natural selection as a complex evolutionary trend. The substantial variability and complexity of pipelines for the reconstruction of mutations and the huge number of genomic sequences are major problems for the analyses of mutations in the SARS-CoV-2 genome. As a solution, we advocate for the development of a centralized database of predicted mutations, which needs to be updated on a regular basis.

An Update on Myocarditis in Forensic Pathology.

Diagnostics (Basel, Switzerland), 14(7):.

In forensic medicine, myocarditis is a complicated topic in the context of sudden death and medical malpractice. A good knowledge of the etiopathology, histopathology, and available literature are both indispensable and essential for the correct management and evaluation of the causal link. Some agents, which are rarely lethal for humans, are not necessarily related to death from myocarditis, even if an infection in other organs such as the gastrointestinal tract is documented. The diagnosis of the causes of death is often difficult and confusing. In some cases, the hypothetical diagnosis of myocarditis as the cause of death is formulated by deduction, causing error and misleading the correct temporal evaluation of pathological events. We reviewed the literature realizing that histomorphological data are scarce and often poorly documented. Only after COVID-19 have the histomorphological aspects of myocarditis been better documented. This is due to poor autopsy practice and poor accuracy in identifying the specific histotype of myocarditis with identification of the responsible agent. We believe that four points are essential for a better understanding and complete diagnosis of the disease: (1) clinical classification of myocarditis; (2) etiological classification of myocarditis; (3) pathophysiology of viral and bacterial infections with host response; and (4) histopathological diagnosis with precise identification of the histotype and pathogen. In the review we provide histological images from authoritative scientific references with the aim of providing useful information and food for thought to readers.

The Respiratory Mechanics of COVID-19 Acute Respiratory Distress Syndrome-Lessons Learned?.

Journal of clinical medicine, 13(7):.

Acute respiratory distress syndrome (ARDS) is a well-defined clinical entity characterized by the acute onset of diffuse pulmonary injury and hypoxemia not explained by fluid overload. The COVID-19 pandemic brought about an unprecedented volume of patients with ARDS and challenged our understanding and clinical approach to treatment of this clinical syndrome. Unique to COVID-19 ARDS is the disruption and dysregulation of the pulmonary vascular compartment caused by the SARS-CoV-2 virus, which is a significant cause of hypoxemia in these patients. As a result, gas exchange does not necessarily correlate with respiratory system compliance and mechanics in COVID-19 ARDS as it does with other etiologies. The purpose of this review is to relate the mechanics of COVID-19 ARDS to its underlying pathophysiologic mechanisms and outline the lessons we have learned in the management of this clinic syndrome.

Drivers of COVID-19 Outcomes in Long-Term Care Facilities Using Multi-Level Analysis: A Systematic Review.

Healthcare (Basel, Switzerland), 12(7):.

This study aimed to identify the individual, organizational, and environmental factors which contributed to COVID-19-related outcomes in long-term care facilities (LTCFs). A systematic review was conducted to summarize and synthesize empirical studies using a multi-level analysis approach to address the identified influential factors. Five databases were searched on 23 May 2023. To be included in the review, studies had to be published in peer-reviewed journals or as grey literature containing relevant statistical data. The Joanna Briggs Institute critical appraisal tool was employed to assess the methodological quality of each article included in this study. Of 2137 citations identified after exclusions, 99 records met the inclusion criteria. The predominant individual, organizational, and environmental factors that were most frequently found associated with the COVID-19 outbreak comprised older age, higher dependency level; lower staffing levels and lower star and subset domain ratings for the facility; and occupancy metrics and co-occurrences of outbreaks in counties and communities where the LTCFs were located, respectively. The primary individual, organizational, and environmental factors frequently linked to COVID-19-related deaths comprised age, and male sex; higher percentages of racial and ethnic minorities in LTCFs, as well as ownership types (including private, for-profit, and chain membership); and higher occupancy metrics and LTCF's size and bed capacity, respectively. Unfolding the risk factors collectively may mitigate the risk of outbreaks and pandemic-related mortality in LTCFs during future endemic and pandemics through developing and improving interventions that address those significant factors.

Ritonavir: 25 Years' Experience of Concomitant Medication Management. A Narrative Review.

Infectious diseases and therapy [Epub ahead of print].

Ritonavir is a potent inhibitor of the cytochrome P450 3A4 enzyme and is commonly used as a pharmacokinetic (PK) enhancer in antiviral therapies because it increases bioavailability of concomitantly administered antivirals. Decades of experience with ritonavir-enhanced HIV therapies and, more recently, COVID-19 therapies demonstrate that boosting doses of ritonavir are well tolerated, with an established safety profile. The mechanisms of PK enhancement by ritonavir result in the potential for drug-drug interactions (DDIs) with several classes of drugs, thus making co-medication management an important consideration with enhanced antiviral therapies. However, rates of DDIs with contraindicated medications are low, suggesting these risks are manageable by infectious disease specialists who have experience with the use of PK enhancers. In this review, we provide an overview of ritonavir's mechanisms of action and describe approaches and resources available to mitigate adverse events and manage concomitant medication in both chronic and short-term settings.

Advance care planning in the treatment of implantable left ventricular assist device: a republication of the review published in Japanese Journal of Artificial Organs.

Journal of artificial organs : the official journal of the Japanese Society for Artificial Organs [Epub ahead of print].

Advance care planning (ACP) is essential in managing serious and chronic illnesses to ensure that patients receive care aligned with their personal values, goals, and preferences. This review focuses on integrating ACP in the treatment of patients receiving implantable left ventricular assist devices (VADs). The heart failure palliative care team developed a unique advance directive form and pamphlet to facilitate ACP discussions, emphasizing not only medical treatment preferences but also patients' values and life goals.The study highlights the distinction between bridge to transplantation (BTT) and destination therapy (DT) in VAD patients, with different goals and considerations for ACP. The use of decision aids developed especially for DT candidates as a communication tool helps in sharing patients' wishes and facilitates shared decision-making, particularly in the complex decisions surrounding DT therapy.Challenges in implementing ACP, such as time constraints due to urgent medical conditions, difficulties in patient communication, and the recent COVID-19 pandemic, are addressed. The need for a comprehensive healthcare system capable of supporting patients' ACP wishes, especially in the community setting, is also pointed out.Future directions include not only developing materials to ease ACP discussions and ensuring that ACP content is shared among healthcare providers to foster collaborative and detailed planning, but also a call for widespread adoption of ACP in Japan.This is a translation of a paper written in Japanese Journal of Artificial Organs (Vol. 52, No. 1, pp. 89-92) with additions and corrections.

Widespread uptake of a future gonorrhea vaccine could decrease the burden of disease and limit the spread of antibiotic resistance. However, gonorrhea vaccination will occur in the backdrop of the roll-out of the coronavirus disease 2019 (COVID-19) vaccine, which could have influenced parental perceptions about other, non-COVID-19 vaccines. In an internet-based cross-sectional survey, 74% of parents would get a gonorrhea vaccine for their child, and this was higher among those whose trust in pharmaceutical companies increased since the start of the COVID-19 pandemic. About 60% of adults aged 18 to 45 would receive a vaccine for themselves.

Gut Microbiota: A Potential Player in Psychiatric Symptoms during COVID-19.

The world journal of biological psychiatry : the official journal of the World Federation of Societies of Biological Psychiatry [Epub ahead of print].

OBJECTIVES: This study aims to explore the potential interconnections among gut microbiota, COVID-19 infection, depression and anxiety disorder. Additionally, it tries to assess potential therapeutic interventions that may improve the dysbiosis of gut microbiota.

METHODS: To achieve these objectives, we reviewed existing literature, encompassing studies and critical reviews that intersect the domains of gut microbiota, COVID-19, depression and anxiety disorders.

RESULTS: The findings highlight a notable correlation between the dysbiosis of gut microbiota and psychiatric symptoms in the context of COVID-19. Specifically, there is a marked reduction in the populations of bacteria that generate anti-inflammatory short-chain fatty acids (SCFAs), alongside a rise in the prevalence of gut bacterial clusters linked to inflammatory processes. Furthermore, several potential treatment strategies were summarized for improving the dysbiosis.

CONCLUSIONS: Gut microbiota plays a significant role in psychiatric symptoms during COVID-19, which has significant implications for the study and prevention of psychiatric symptoms in major epidemic diseases.

Fibromyalgia: one year in review 2024.

Clinical and experimental rheumatology pii:20957 [Epub ahead of print].

Fibromyalgia (FM) remains a condition with a pathogenesis that is not completely understood, affecting a significant portion of the global population. This article summarises the main advances in FM during the last year. Even in 2023, research on FM was notably active. From a clinimetric perspective, studies have been conducted to evaluate the possibilities of interchanging the primary indices of disease severity, primarily for studies with substantial case numbers. Regarding FM pathogenesis, ongoing research focuses on small fiber neuropathy: some studies have documented its association with central sensitisation, while others have revealed distinct sensory profiles in patients with FM and small fiber neuropathy compared to those solely with small fiber neuropathy. Dorsal root ganglia seem to play a crucial role in the pathogenesis of FM as they host satellite glial cells, which are targeted by pain-driving immunoglobulin G. These antibodies have been identified in a subset of patients exhibiting high symptom severity. An important study conducted on animal models confirmed the role of neuroinflammation at the level of dorsal root ganglia, in this case mediated by polymorphonuclear neutrophils. Mounting evidence underscores the link between COVID-19 and the persistence of FM symptoms after recovery. In identifying potential biomarkers aiding FM diagnosis, research has also concentrated on studying the expression of specific circulating microRNAs. Recent discoveries have unveiled novel therapeutic strategies for FM, especially focused in non-pharmacological interventions. This includes a focus on non-invasive brain stimulation and exercise programs, all directed towards relieving symptoms and improving functionality in individuals affected by the condition.

However, growing demand for clinical placements continues to be a challenge in providing sufficient RPL opportunities. The COVID-19 pandemic forced academic institutions to rethink the delivery of traditional clinical training and innovations in online clinical learning experiences, specifically livestreamed clinical experiences, have emerged which show promise in addressing the capacity limitations of traditional placements. Although previous reviews have explored the use of livestreamed clinical experiences during the pandemic, there is a lack of rigorous theoretical framing to support these innovations.

OBJECTIVES: The aim of this review is two-fold: to examine the effectiveness of livestreamed clinical experiences through an experience-based learning (ExBL) theory perspective and to provide practical recommendations to optimise and implement these innovations.

METHODS: A review of literature was conducted to identify journal articles published between September 2019 and January 2023 reporting on innovations relating to livestreamed clinical experiences. The search focused on undergraduate and postgraduate medical education but relevant evidence from other healthcare professions were also included due to a limited evidence base. Strengths and weaknesses were derived from the literature and analysed in relation to ExBL components.

RESULTS: Principal strengths of livestreamed clinical experiences included expanded access to RPL opportunities and medical specialties, enhanced standardisation of learning experiences and positive perceptions from students regarding convenience. Clinical educators found these innovations enabled teaching at scale. Patients did not perceive such innovations to negatively impact their standard of care. Limitations included the inability to practice physical examination skills, challenges in ensuring learner engagement and connectivity issues.

CONCLUSION: Livestreamed clinical experiences have the potential to effectively expand placement capacity and provide high-quality educational experiences for medical students. Although certain limitations exist, technological and pedagogical adaptations can help overcome these challenges. The application of theoretical frameworks to future online innovations will be fundamental to ensure effective clinical learning.

Ivermectin: A Multifaceted Drug With a Potential Beyond Anti-parasitic Therapy.

Cureus, 16(3):e56025.

Ivermectin was first discovered in the 1970s by Japanese microbiologist Satoshi Omura and Irish parasitologist William C. Campbell. Ivermectin has become a versatile pharmaceutical over the past 50 years. Ivermectin is a derivative of avermectin originally used to treat parasitic infections. Emerging literature has suggested that its role goes beyond this and may help treat inflammatory conditions, viral infections, and cancers. Ivermectin's anti-parasitic, anti-inflammatory, anti-viral, and anticancer effects were explored. Its traditional mechanism of action in parasitic diseases, such as scabies and malaria, rests on its ability to interfere with the glutamate-gated chloride channels in invertebrates and the lack of P-glycoprotein in many parasites. More recently, it has been discovered that the ability of ivermectin to block the nuclear factor kappa-light-chain enhancer of the activated B (NF-κB) pathway that modulates the expression and production of proinflammatory cytokines is implicated in its role as an anti-inflammatory agent to treat rosacea. Ivermectin has also been evaluated for treating infections caused by viruses, such as SARS-CoV-2 and adenoviruses, through inhibition of viral protein transportation and acting on the importin α/β1 interface. It has also been suggested that ivermectin can inhibit the proliferation of tumorigenic cells through various pathways that lead to the management of certain cancers. The review aimed to evaluate its multifaceted effects and potential clinical applications beyond its traditional use as an anthelmintic agent.

ESP Quick Facts

ESP Origins

In the early 1990's, Robert Robbins was a faculty member at Johns Hopkins, where he directed the informatics core of GDB — the human gene-mapping database of the international human genome project. To share papers with colleagues around the world, he set up a small paper-sharing section on his personal web page. This small project evolved into The Electronic Scholarly Publishing Project.

ESP Support

In 1995, Robbins became the VP/IT of the Fred Hutchinson Cancer Research Center in Seattle, WA. Soon after arriving in Seattle, Robbins secured funding, through the ELSI component of the US Human Genome Project, to create the original ESP.ORG web site, with the formal goal of providing free, world-wide access to the literature of classical genetics.

ESP Rationale

Although the methods of molecular biology can seem almost magical to the uninitiated, the original techniques of classical genetics are readily appreciated by one and all: cross individuals that differ in some inherited trait, collect all of the progeny, score their attributes, and propose mechanisms to explain the patterns of inheritance observed.

ESP Goal

In reading the early works of classical genetics, one is drawn, almost inexorably, into ever more complex models, until molecular explanations begin to seem both necessary and natural. At that point, the tools for understanding genome research are at hand. Assisting readers reach this point was the original goal of The Electronic Scholarly Publishing Project.

ESP Usage

Usage of the site grew rapidly and has remained high. Faculty began to use the site for their assigned readings. Other on-line publishers, ranging from The New York Times to Nature referenced ESP materials in their own publications. Nobel laureates (e.g., Joshua Lederberg) regularly used the site and even wrote to suggest changes and improvements.

ESP Content

When the site began, no journals were making their early content available in digital format. As a result, ESP was obliged to digitize classic literature before it could be made available. For many important papers — such as Mendel's original paper or the first genetic map — ESP had to produce entirely new typeset versions of the works, if they were to be available in a high-quality format.

ESP Help

Early support from the DOE component of the Human Genome Project was critically important for getting the ESP project on a firm foundation. Since that funding ended (nearly 20 years ago), the project has been operated as a purely volunteer effort. Anyone wishing to assist in these efforts should send an email to Robbins.

ESP Plans

With the development of methods for adding typeset side notes to PDF files, the ESP project now plans to add annotated versions of some classical papers to its holdings. We also plan to add new reference and pedagogical material. We have already started providing regularly updated, comprehensive bibliographies to the ESP.ORG site.

With the world now in the middle of a new and rapidly spreading pandemic, now is the time to read this book, originally published in 2012, that describes animal infections and the next human pandemic (that's actually the book's subtitle). You would be hard pressed to find a more relevant explanation of how this got started and why there will be more after this one. R. Robbins

Papers in Classical Genetics

The ESP began as an effort to share a handful of key papers from the early days of classical genetics. Now the collection has grown to include hundreds of papers, in full-text format.

Digital Books

Along with papers on classical genetics, ESP offers a collection of full-text digital books, including many works by Darwin and even a collection of poetry — Chicago Poems by Carl Sandburg.

Timelines

ESP now offers a large collection of user-selected side-by-side timelines (e.g., all science vs. all other categories, or arts and culture vs. world history), designed to provide a comparative context for appreciating world events.

Biographies

Biographical information about many key scientists (e.g., Walter Sutton).

Selected Bibliographies

Bibliographies on several topics of potential interest to the ESP community are automatically maintained and generated on the ESP site.
