COVID-19 Clinical Trials and Expanded Access

To provide optimal care to patients and to maintain long-term institutional viability, Transplant Centres (TC) must have an awareness of their patients' health status, their health care needs and priorities, as well as their access to information and health care. For example, it is critical that TCs understand whether their patients are medically suitable for transplant, whether transplantation remains a priority for their patients, how best to communicate with their patients, and whether their patients have sufficient access to medications and health care to undergo transplant safely. The COVID-19 pandemic has had a tremendous impact on people and institutions around the country in a short period of time. At this time, little is known regarding its impact on the transplant community specifically. For example, it has been reported that around 8 million French applied for partial unemployment benefit over the past month, but it is not known if this has affected transplant patients. It has been reported that people with significant chronic medical conditions and those with compromised immune systems may be at increased risk of dying from the COVID-19, but it is not known if this has affected patients' interest in receiving transplants at this time. The "Société Francophone de Transplantation (SFT)" published recommendations at the beginning of the pandemic in order to limit the rate of infection in these high-risk population. The purpose of this study is to better understand the impact of COVID-19 on patients on the waiting list and transplant patients. Further, a better understand on how patients have received information about this pandemic and how best to communicate with them.

The purpose is to investigate the COVID-19 prevalence, associated morbidity and long-term cognitive deficits in consecutive patients presenting with acute neurological symptoms

The article presents a protocol of a cross-sectional study of mental health of pregnant women in relation to the COVID 19 pandemic. The primary aim is to compare differences in anxiety and depression scores of pregnant women between countries affected by the COVID-19 pandemic. The secondary aim is to assess demographic, economic, and social aspects affecting maternal anxiety and depression scores among pregnant women worldwide in the time of the COVID-19 pandemic. Finally, investigators will be able to compare differences in perception of the different aspects of the COVID-19 pandemic (social distancing, restrictions related to delivery) between countries and according to the epidemic status (number of infected patients, number of reported deaths). The comparisons will also be done according to COVID-19 status of the participants.

Background: Researchers think that people s mental health and behavior will be very affected by the steps taken to slow the spread of COVID-19, such as social distancing. Also, the threat of disease and death, to people and their loved ones, can cause much stress. Researchers want to learn more about these stressors and how they are affecting people. Objective: To study the relationship of affective, cognitive, and behavioral responses to stressors related to COVID-19 with neuroimaging and behavioral data collected before COVID-19. Eligibility: English-speaking adults age 18 and older Design: This online study will include both new participants and those who have taken part in past National Institute of Mental Health studies. All will complete the same surveys and tasks. Participants will give their name and email address. They will get a username and password. The file that links their username to their personal data will be kept secure. Participants will complete a set of surveys about the following: - Sociodemographic data, such age, race, and income - Education and work status - Mental and medical illness and treatment - Family medical history - Mood - COVID-19 experience - Anxiety - Substance and alcohol use - Attention control - Other mental health related topics. Participants will complete a finger-tapping task. For this, they will press a key a certain number of times in a limited period. They will get to practice the task. After the task, they will complete a survey about it. It will take about 1 hour to complete the surveys and the task. About 8 months later, participants will be contacted to repeat the surveys and task. Compensation is provided.

Collect informations on the health status of transplanted patients (kidney, kidney / pancreas, pancreas or pancreatic islet) during the COVID-19 pandemic. All informations will be collected by short questionnaire via phone.

The Harnessing Online Peer Education COVID-19 (HOPE COVID-19) intervention will assess whether a peer-led online support community can improve behavioral health outcomes related to COVID-19.

The purpose of this study is to evaluate the safety of administration of plasma containing antibodies to the SARS-CoV-2 virus (i.e., convalescent plasma) and if it is able to prevent disease or lessen the severity of disease in individuals who are at high risk of developing COVID-19 due to a recent exposure. This study will also measure the level of anti-SARS-CoV-2 antibodies in patient's blood after the administration of the convalescent plasma.

The new Severe acute respiratory syndrome coronavirus (SARS-CoV-2) named coronavirus disease 2019 (COVID-19) is currently responsible for a pandemic spread of febrile respiratory infections, responsible for a veritable global health crisis. In adults, several evolutionary patterns are observed: i) a/pauci-symptomatic forms; ii) severe forms immediately linked to rare extensive viral pneumonia; and iii) forms of moderate severity, some of which progress to secondary aggravation (Day 7-Day 10). Children can be affected, but are more rarely symptomatic and severe pediatric forms are exceptional. Like some other coronaviruses (SARS-CoV and Middle East respiratory syndrome coronavirus (MERS-CoV)), these differences in clinical expression could be based on a variability in the immunological response, notably either via inhibition of the type I interferon (IFN-I) response, or on the contrary an immunological dysregulation responsible for a "cytokine storm" associated with the aggravation. Little is known about the impact of these innate immune response abnormalities on the adaptive response. In addition, certain genetic factors predisposing to a state of "hyper-fragility" and certain viral virulence factors could also be predictive of the clinical response. In this context, the main hypothesis is that the virological analysis and the initial biological and immunological profiles are correlated with the initial clinical presentation of COVID-19 infection. In particular, children forms and pauci-symptomatic disease in adults may be linked to a more robust innate immune response, including better production of IFN-I.

A rapid oxygen desaturation has observed in patients with COVID-19 which have seriously respiratory failure and most of them have intubated and connected to the mechanical ventilator. Finally, many of them have died during the process. ORF8 and superficial glycoproteins of a novel coronavirus bind to porphyrin on haemoglobin molecules and inhibit heme metabolism in an erythrocyte. However, it is not clarify the effects of the novel coronavirus on mean corpuscular volume (MCV), mean corpuscular of haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC).

This is a PET/CT study using the 18F-αvβ6-binding-peptide.The goal of this study is to evaluate this peptide in patients after infection with SARS CoV2.
