Viruses are a major health problem for the general public and at risk populations.Normally, detection of antibody titers is the gold standard for determining theeffectiveness of the immune system following natural or vaccine caused immunization.However, determining the effectiveness of other parts of the immune system are lesscommon due to the difficulties with testing. Furthermore, there is a critical need toaddress other therapies in case vaccination is not successful in immuncompromisedpopulations. Exercise has been shown to increase the strength of the immune systemagainst many types of viruses and therefore could be simple way to improve immunityagainst the COVID-19 virus. The aim of this research is to determine the effects ofexercise on anti-viral immunity against many types of common viruses before and aftervaccination. We hypothesize that exercise will enhance the anti-viral immunity before andafter vaccination.Up to 30 healthy volunteers (age 18-44 years) will be recruited to participate in thisstudy. For completion of Aim 1, three visits are needed totaling around 7 hours of thepatient's time and for Aim 2, three visits are needed totaling around 4.5 hours of thepatient's time. The initial visit will be for pre-screening and if deemed healthy enoughto participate, an exercise test to determine the VO2 max of the participant will beconducted. The following visits will require a trained phlebotomist to insert anin-dwelling catheter and participants will undergo a 20-minute incremental exercisetrial. Approximately 50mL of blood will be collected at four different timepoints: atrest, 60% VO2 max, 80% VO2 max, and 1-hr post-exercise. All four collected blood sampleswill be used to expand viral specific T-cells and compare IFN-γ rele

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused pandemic sinceoutbreak in 2020.Patients with chronic liver disease (CLD) are at higher risk ofmortality and morbidity due to COVID-19. Despite there is a large number of clinicaltrials of COVID-19 vaccines, only a few participants with chronic liver diseases wereincluded.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused pandemic sinceoutbreak in 2020. Patients with cancers may be at higher risk than those without cancerfor coronavirus disease 2019 (COVID-19). At present, limited data are available on thesafety and immunogenicity of COVID-19 vaccination for patients with cancer.

The coronavirus (COVID-19) pandemic is a significant psychological stressor thatthreatens the onset of a mental health crisis in the US. Fear and anxiety about COVID-19and its economic impact, as well as loneliness due to the required social isolation, aredriving the mental health impacts of COVID-19; in a recent Kaiser Family Foundation poll,45% of respondents reported that the coronavirus has had a negative impact on theirmental health. This is reflected in Southeastern Ohio. In data that the investigatorscollected from 317 Ohio University faculty, staff, and students from late May to earlyJune, 39% reported moderate-to-severe levels of anxiety, 41% reported moderate-to-severelevels of depression and 57% reported the COVID-19 outbreak was impacting their sense ofsocial connection much or very much. Despite the significant community need foraccessible and affordable care, there are currently no evidence-based interventions forindividuals coping poorly with coronavirus-related distress. The investigators havedeveloped a virtual group-based intervention targeting cognitive biases that amplify theexperience of stress and anxiety (i.e., amplifying cognitions; Coping withCoronavirus-Related Emotion and Worry [COPING CREW]). The next step in developing thisintervention in a scientifically rigorous manner is to refine the manual and proceduresand conduct a pilot test of the intervention.

Evaluation of the efficacy of the AstrazenicaCovid 19 vaccine to develop IgG antibody andits level based on th12 weeks program. Also to follow the changes of markers ofcoagulation (D-dimer) after vaccination compared to the basic level. A cardiologyconsultant will follow D-Dimer results to be managed properly if there is a need. As itis expected to receive Sinopharm vaccine there will be comparison between results of thetwo types of vaccine. To our knowledge this will be the first study done on Egyptianpopulation.

This is an interventional new drug clinical trial for a Phase 2 randomized, double-blind,and placebo control study using intravenous injection of allogeneic adipose stem cells(Celltex AdMSCs) for subjects with severe COVID-19.

SARS-CoV2 is responsible for a pandemic that has been evolving for approximately 18months. The virus' capacity for dissemination and its virulence are responsible forsignificant morbidity and mortality. The initial lack of knowledge of the pathogen and ofthe pathophysiology underlying the potential severity of the disease, particularly in therespiratory tract, led to numerous therapeutic attempts in this emergency context,centered on the control of an obviously exaggerated inflammatory response. A large numberof studies remained of insufficient quality to lead to relevant and applicableconclusions. Secondly, the benefit of corticosteroid therapy has been demonstrated in twotrials. Although Dexamethasone remains the only corticosteroid to improve survival, theseresults have reinforced the hypothesis of the interest of treatments reducing theinflammatory response, particularly cytokine. The widespread use, in the absence ofscientific data, of interleukin-6 receptor inhibitors (Sarilumab and Tocilizumab) hasbeen structured around studies whose results remain uncertain to this day because of theheterogeneity of the population treated and the results observed. A possible survivalbenefit seems to emerge for resuscitation patients who have not yet required invasiveventilation, the other situations being probably associated with the absence of effect oreven the potential danger of this treatment. Tocilizumab is notably associated in theliterature with the risk of secondary infections and mucosal healing abnormalities,favoring bleeding complications and digestive perforations. The objective of this studyis to evaluate the risk of digestive complications (hemorrhage, perforation,diverticulitis) and infectious complications related to the use of Tocilizumab accordingto the severity of the patients.

This is a phase Ⅰ/Ⅱ, single-center, randomized, double-blind, placebo-controlled study,to evaluate the safety, tolerability and immunogenicity of the recombinant COVID-19vaccine (Sf9 cells) in the subjects from healthy aged 6-17 years with immunizationprocedures 0, 21, 42 days and doses (10μg/20μg/40μg).

This is an open label randomized controlled clinical trial which was designed to confirmthe potential efficacy and safety of favipiravir in the management of patients with mildto moderate COVID-19 compared to best supportive care.

The aim of this study is to determine the impact of systemic immunosuppression onsustained antibody COVID-19 concentrations in patients with IBD who received a COVID-19vaccine.
