COVID-19 Clinical Trials and Expanded Access

The current outbreak of Covid-19 requires the wearing of FFP2 respiratory protective devices by healthcare personnel to limit their contamination. However, there is currently a shortage of masks in France due to insufficient national stocks while the disease is spreading. There is an urgent need to save FFP2 masks to enable healthcare personnel to continue to provide care in complete safety. Contamination of staff due to insufficient masks would have consequences by limiting access to care for infected patients and putting caregivers at potential risk of death. Caregiver protection is also intended to contain the risk of nosocomial epidemics. We propose the use of ARFC masks by Covid-19+ units. These ARFC masks provide optimal security against the risk of aerosolization of contaminated biological liquids. They are masks modified to be usable by civilians, resulting from the technology of combat masks, specially designed for use in NRBC (Nuclear, Radiological, Biological and Chemical) atmosphere.

This study is a randomized controlled trial (RCT) of the four-week Healthy Minds Program (HMP) app Foundations training in employees of a mid-size urban school district in the United States during the summer of 2020, in the midst of the novel coronavirus pandemic. A 3-month follow-up in the fall of 2020 will also be conducted. Participants will be recruited via email and mailed postcards, and will first complete an online screen. Eligible participants will then enter a waiting zone for between 2-days and 2-weeks before they are sent the online pre-test. Upon completion of the pre-test, participants will be assigned to condition via a simple random number generator. If assigned to the intervention (i.e., the Healthy Minds Program App), participants will receive instructions and support in downloading and activating the app. Every 7-days over the 4-week intervention period participants in both conditions will complete the same set of measures. A full battery of measures will be administered a second time post-test, following the 4-week intervention period. Three-months after post-test, a follow-up assessment will be conducted. The investigators predict that participants assigned to the intervention will demonstrate significantly reduced psychological distress after the intervention, and these decreases will persist at the 3-month follow-up. Further, it is hypothesized that baseline participant characteristics and early experience of the intervention will predict treatment adherence, study drop-out and outcomes, and that treatment engagement will moderate outcomes.

We have developed an online learning resource designed to support healthcare staff during and after the COVID-19 pandemic. This resource has been produced in anticipation of the psychological effect of working during this time. This is an open access, free, online resource available here: https://www.nottingham.ac.uk/toolkits/play_22794 It is designed to be relevant for healthcare staff, and we are evaluating it now with healthcare students as our next generation of healthcare staff. We are interested in knowing more about your views of healthcare students towards this package. This will help us to determine its value as a learning resource to support psychological wellbeing in healthcare students, alongside other welfare supports. The aim is to describe the views of healthcare students towards an e-learning package developed in response to COVID-19 on Psychological Wellbeing for Healthcare Workers.

Several recent studies point to the possibility of the new coronavirus (SARS-Cov2), which currently causes pandemic COVID-19, to infiltrate the central nervous system (CNS) and cause primary damage to neural tissues, increasing the morbidity and mortality of these patients. A pathophysiological hypothesis for insulting the CNS would be the impairment of cerebral compliance (CC), because elevation of intracranial pressure (ICP), but due to the invasive nature of the methods available for ICP evaluation, this hypothesis has so far not been verified. Recently, a noninvasive technique was developed to evaluate CC (B4C sensor), making it possible to analyse CC in patients outside the neurosurgical environment. Therefore, the main objective of this study was to assess the presence of CC impairment in patients with COVID-19, and observe potential influences of this syndrome on cerebral hemodynamics.

Several studies have shown that smokers have a higher risk of developing a severe form of COVID-19 once a person has been infected. This is explained by the damage caused by smoking at the bronchopulmonary level and an overexpression of some coronavirus receptors at the pulmonary level when exposed to tobacco. In contrast, recent data indicate that smokers are proportionally less infected with the COVID-19 virus since all available cohort data from around the world show a very low rate of smokers among COVID-19 infected subjects. The mechanisms at the origin of this protective effect are not known. All of these data lead us to question the real role of nicotine in the protective effect of tobacco observed in the general population against infection by the COVID-19 virus. The objectives are : - To show that subjects taking nicotine substitutes as part of a smoking cessation program are less infected with COVID-19 than non-smokers. - To show that active smokers are less infected with COVID-19 than non-smokers. - To compare the percentage of positive serological tests in subjects taking nicotine substitutes to the percentage of positive serological tests in active smokers.

The aim of this study is to assess the effect of a home-based exercise training during social isolation due to covid-19 pandemic in patients who undertook bariatric surgery.

The authors hypothesized that inhaled sedation, either with isoflurane or sevoflurane, might be associated with improved clinical outcomes in patients with COVID-19-related ARDS, compared to intravenous sedation. The authors therefore designed the "Inhaled Sedation for COVID-19-related ARDS" (ISCA) non-interventional, observational, multicenter study of data collected from the patients' medical records in order to: 1. assess the efficacy of inhaled sedation in improving a composite outcome of mortality and time off the ventilator at 28 days in patients with COVID-19-related ARDS, in comparison to a control group receiving intravenous sedation (primary objective), 2. investigate the effects of inhaled sedation, compared to intravenous sedation, on lung function as assessed by gas exchange and physiologic measures in patients with COVID-19-related ARDS (secondary objective), 3. report sedation practice patterns in critically ill patients during the COVID-19 pandemics (secondary objective).

This study is a randomized, double-blinded, and placebo controlled phase 1&2 clinical trial of the SARS-CoV-2 inactivated vaccine manufactured by Sinovac Life Sciences Co. , Ltd. The purpose of this study is to evaluate the safety and immunogenicity of the experimental vaccine in healthy elderly aged 60 years and above.

In this study, the investigators propose to analyse the clinical data of all patients admitted in Geneva University Hospitals (HUG) or in a care center in Geneva who are diagnosed with COVID-19. CVD being one of the most important risk factors for developing a severe form of the disease, the investigators will explore the prognosis and clinical outcomes of those patients according to their CVD history as well as newly onset CVD during hospitalization. Moreover, as further evidence is needed on the use of renin-angiotensin-aldosterone system (RAAS) inhibitors for SARS-CoV-2 infected patients, the investigators will study prognosis and outcomes according to the patients' medications. Finally, the investigators propose to evaluate hospital length of stay and cost. The aim, therefore, is to collect information and scientific evidence from patients hospitalized and diagnosed positive for COVID-19, in order to evaluate if previous (or newly onset) CVD may influence outcomes and costs.

Convalescent plasma has been shown to be safe and effective for treatment of several diseases. Preliminary data indicates that it is safe and effective for treatment of COVID. However, data is limited to small studies and case series on severely ill patients. In a preliminary safety study 10 patients with severe COVID-19, defined as requiring supplementary oxygen, having fever and a duration of illness less than 11 days were treated with 200 ml of CP. CP was given as a slow infusion without obvious adverse events. Eight patients had viremia. One patient rapidly cleared the virus and recovered following CP treatment. CP infusion did not appear to clear viremia in 7/8 patients. Five of these were eventually admitted to ICU. Thus CP did not appear to cause acute toxicity but did not seem to be effective at the dose used. Viremia seemed to be a marker of a high risk of disease progression The proposed study thus aims to treat a high risk population identified by having viremia irrespective of but hopefully before they develop pulmonary injury such that they require supplementary oxygen therapy. Moreover the dose of plasma will be increased incrementally with the aim of clearing viremia as our initial study indicates that continued viremia is driving COVID-19.
