COVID-19 Clinical Trials and Expanded Access

The purpose of this study is to determine whether sleep disturbances in children aged 7 to 12 during COVID-19 containment are more prevalent in children who received routine psychiatric care before containment compared to children who don't have any psychiatric care.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is currently spreading rapidly around the globe, causing a major public health issue. There is currently very few data about the impact of COVID-19 on pregnancy, and potential in utero infection. This is a prospective observational study of COVID-19 diagnosed pregnant patients. This objective is to examine the impact of COVID-19 during pregnancy on the rates of obstetric and perinatal complications.

This interventional study will investigate the effect of daily use of a mindfulness app on measures of participant anxiety, well-being, and future outlook during the Covid-19 pandemic, by comparing pre-intervention survey responses to post-intervention survey responses.

Coronavirus COVID-19 is an emerging virus also called Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). Eighty percent of patients are poor or asymptomatic. However, there are major respiratory complications for some patients, requiring intensive care hospitalization and possibly leading to death in 5% of cases. One of the hypotheses put forward is that much of the pathophysiology is due to endothelial dysfunction associated with disseminated intravascular coagulation. The covid-19 pathology could induce coagulation impairment as observed during sepsis. An increase in D-dimer levels during covid-19 disease is itself associated with excess mortality. While D-dimers are highly sensitive, they are not specific for clotting activity. They may be increased in many other circumstances, particularly in inflammation. On the other hand, the infection stimulates the release of extracellular vesicles. These vesicles, of multiple cellular origin, are an actor of vascular homeostasis, and participate in the state of hyperactivation of coagulation. They have a major role in the prothrombotic state and the development of coagulopathy associated with sepsis. The aim of our monocentric prospective study would be to study early and more specific markers of hypercoagulability and markers of routine endothelial dysfunction, as soon as the patient is hospitalized, in order to predict the risk of hospitalization in intensive care.

This study is a case-control study to characterize the molecular and cellular anomalies of the olfactory epithelium of COVID-19 patients with isolated anosmia, by comparison with the olfactory epithelium of non-infected subjects.

The International Registry of Coronavirus Exposure in Pregnancy (IRCEP) is a prospective cohort study of pregnant and recently pregnant women who have been tested for SARS-CoV-2 (regardless of the result) or have been clinically diagnosed with COVID-19 by a health care professional. Data from the IRCEP will be used to evaluate the impact of COVID-19 on pregnancy and birth outcomes.

The administration of Calcifediol in patients with COVID-19, will reduce the development of SARS and the worsening of the various phases of the syndrome. Reducing at least 25% in ICU admission and death from the process, reducing days of hospitalization, facilitating the recovery of the same, acting significantly and positively, in any of its phases throughout the natural history of illness. As a treatment with extensive experience of clinical use, safe, inexpensive, and potentially very effective, it will have a highly efficient cost-benefit impact on the prevention of SARS.

The objective of the study is to develop and validate a molecular diagnostic strategy (RT-ddPCR multiplex) of COVID-19 based on a saliva sample and alternative to the RT-qPCR method, in order to : 1. to compensate for the risk of a shortage of diagnostic kits, reagents and materials necessary for molecular diagnosis; 2. to increase the molecular diagnostic capacity of COVID-19 at the Rouen University Hospital; 3. and to have a method compatible with screening extended to populations at risk.

The SARS-CoV-2 pandemic has resulted in an international shortage of the nasopharyngeal (NP) swabs used to collect sample for virological testing. This shortage has become a crisis as testing capacity is growing, and threatens to become the bottleneck at University of Virginia Health System and in the Commonwealth of Virginia, as it already is in other testing centers. To resolve this crisis, a team in the Clinical Microbiology Laboratories at University of Virginia Medical Center has been working closely with biomedical engineers in the University of Virginia (UVA), School of Engineering and with high volume domestic manufacturers developing injection molded polypropylene flocked nylon NP swab. This prototype will be tested for non-inferiority relative to existing, already validated NP swabs ("control swab") for purposes of molecular microbiology: i.e. the polymerase chain reaction (PCR) tests used for virological testing for SARS-CoV-2. Specifically, the nasopharynx of patients with Covid-19 and patients under investigation (PUI) for Covid-19, the disease caused by SARS-CoV-2, will be swabbed using a prototype swab and a control swab (the standard of care swab), and test for concordance of SARS-CoV-2. In all cases the swab will be transported in validated FDA cleared viral transport medium (VTM) as per standard operating procedure at University of Virginia Medical Center.

The purpose of this study is to determine whether a higher dose of low molecular weight heparin (enoxaparin 40 mg b.i.d.) is superior than the standard prophylaxis dose (enoxaparin 40 mg o.d.) in reducing thromboembolic events in COVID-19 patients.
