Clinical Trials and Expanded Access

The main aim of the study is to estimate the potential efficacy of i.v. canrenone as add-on therapy on maximal medical treatment versus maximal medical treatment alone in treating moderate-to-severe ARDS due to SARS-CoV-2.

This 2-arm clustered, randomized community trial will test a multilevel, COVID-19 testing and linkage to care (eg, health insurance, medical appointments, community resources, contact tracing) intervention against a nontailored, attention-control condition on uptake of COVID-19 testing with adult African American church-affiliated members at 6 months. Contact tracing approval (beliefs and participation contact tracing) and COVID19 prevention behaviors will also be examined. Findings from this study could provide a theory-based, multilevel model for delivering scalable, wide-reaching COVID-19 testing and linkage to care services, including contact tracing, by supporting African American faith leaders with culturally-appropriate, easy-to-use tools and health agency partnerships.

This study was aimed to evaluate the post-infection cognitive functions of adult individuals with COVID-19. 50 individuals with COVID-19 and 50 healthy control groups were included in the study. Cognitive functions of individuals with COVID19 compared with healthy individuals.

The increased risk of transmission of COVID-19 infection causes the incidence of death in health workers to escalate. It requires further research on risk factors and intervention in health worker professionals, especially on immunity factors and nutritional status. Quality of diet and nutrition is very important to support the immune system when infected. Several probiotic strains have been shown to decrease the duration and incidence of diarrhea and respiratory infections, suggesting the Gut-Lung Axis pathway. Some probiotics also improve the balance of diversity in the composition of the gut microbiota and affect body weight in obese people. Probiotics have also been shown to improve vitamin D absorption. A combination of vitamin D and probiotics may be an alternative to reduce gut dysbiosis that will directly or indirectly reduce the risk and severity of viral infections including SARS-CoV-2.

Background: Some people have allergic reactions to COVID-19 mRNA vaccines. Researchers want to learn more about these reactions to provide guidance on who can safely receive the vaccines, including a second dose in people who had a reaction to the first. Objective: To study the safety of giving a second mRNA COVID-19 vaccine dose to people who had a systemic allergic reaction to their first dose. Eligibility: People aged 18-69 who had a systemic allergic reaction to their first dose of COVID-19 vaccine. Design: Individuals who have underlying health issues may need to come to the NIH for screening tests to make sure they are safe to receive the vaccine . People who are eligible to participate in the study will be admitted to the NIH hospital and stay for at least 4 days. They will give a urine sample. They will have a nasal swab SARS-CoV-2 test. They will have an intravenous line placed in each arm. They will get the study vaccine (Pfizer-BioNTech COVID-19 vaccine) and one dose of placebo on different days. They will have breathing tests. They may have clinical photography if they develop a rash. Participants will have 3 follow-up visits . They will have allergy skin testing at one visit. Drops of different allergens or controls will be placed on their back or arm. The skin under each drop will be scratched with a tool. If the results are negative, a small amount of allergen will be injected just below the surface of their skin. Participation will last for 6 months .

Since the beginning of the pandemic, several authors (Lee, 2020; Sahu, 2020; Zhai & Du, 2020) have highlighted the various challenges faced by university students, as well as their negative effects on their mental health. A deterioration in their mental health was observed, particularly during lockdown, with very high levels of anxiety and depressive symptoms (Essadek & Rabeyron, 2020; Husky et al., 2020; Le Vigouroux et al., 2021; Odriozola-González et al., 2020). In addition, COVID-19 has brought about a digital revolution in higher education (Strielkowski, 2020). However, distance learning was not without consequences on student stress (IAU, 2020). The detrimental effects of distance education, in terms of stress and anxiety, could also have important consequences for students' learning and academic success. Our research proposes to evaluate effects of an intervention focused on stress and learning on mental health and learning strategies. This intervention will be proposed to students from University of Nimes. Its primary objective is to prevent psychological health alterations and to improve students' learning strategies. Three groups will be constituted: a group that will participate in an online program (online group), a group will participate in a hybrid program, i.e. with online content and face-to-face support (hybrid group) and a group that will not be receiving any interventions (control group). The investigators plan to include between 150 and 200 university students, between 40 and 70 in each group. The levels of mental health and learning strategies of the two experimental group (online and hybrid group) will be compared to a control group with the realization of pre and post intervention measures. Sociodemographic (e.g., level education) and situational variables (e.g., diagnostic of COVID-19) will be considered in the analyses.

This phase II trial studies the immune response to COH04S1 compared to Emergency Use Authorization (EUA) SARS-COV-2 vaccine in patients with blood cancer who have received stem cell transplant or cellular therapy. COH04S1 belongs to a category called modified vaccinia Ankara (MVA) vaccines, created from a new version of MVA, called synthetic MVA. COH04S1 works by inducing immunity (the ability to recognize and fight against an infection) to SARS-CoV-2. The immune system is stimulated to produce antibodies against SARS-CoV-2 that would block the virus from entering healthy cells. The immune system also grows new disease fighting T cells that can recognize and destroy infected cells. Giving COH04S1 after cellular therapy may work better in reducing the chances of contracting coronavirus disease 2019 (COVID-19) or developing a severe form of COVID-19 disease in patients with blood cancer compared to EUA SARS-CoV-2 vaccine.

The long-term goal of the study is to mitigate the spread of the pandemic in miners, a population of high-risk, rural essential workers who are susceptible and vulnerable to COVID-19, partly based on exposure to particulate air pollution, and who are predominantly racial/ethnic minorities in New Mexico (NM) (3, 11). The study objective is to provide proof-of-principle for frequent point-of-care molecular testing as a workplace surveillance tool to monitor and prevent the spread of SARS-CoV-2 infection in this unique population. The central hypothesis is that frequent workplace molecular surveillance is an effective method to reduce SARS-CoV-2 infection and discover novel host risk factors for the virus. The site of molecular surveillance (intervention site) will be a surface coal mine in McKinley County, NM, located just outside the Eastern Agency of the Navajo Nation, comprised of 66% minority miners. This site offers a unique opportunity for a community-based study of SARS-CoV-2 infection in this population. Miners at the intervention site will provide nasal swabs before beginning their work shift on alternate days that will be analyzed with a 'screening' molecular test (12). This test is ideal because it is low cost, simple, portable, point-of-care, rapid, and can be performed by minimally trained professionals in low-infrastructure settings. The control site is a similar coal mine in Campbell County, Wyoming (WY). Both mines, operated by the same company, have similar engineering, administrative, and personal protective measures in place. The rationale for this study is to establish the suitability of longitudinal molecular surveillance to prevent and control SARS-CoV-2 infection in this unique population by completing the following specific aims.
