COVID-19 Clinical Trials and Expanded Access

This multicenter, randomized, double-blind, placebo-controlled clinical trial will evaluate the efficacy and safety of intravenous Sodium Nitrite Injection for treatment of patients infected with COVID-19 who develop lung injury and require mechanical ventilation.

The investigators aimed to investigate the clinical and epidemiological characteristics of neonates who will be born to Covid-19 positive mothers in Turkey. It is a multicentric prospective cohort study designed and destined only in Turkey. The investigators are planning to admit more than 20 Neonatal Intensive Care Units into the survey; nevertheless, the total number may change according to the prevalence of Covid-19 in neonates. The investigators will also inquire into vertical transmission by collecting cord blood, placental, and postnatal serum samples to test for Covid-19 PCR and Covid-19 Ig M and IgG values from the neonates.

The World Health Organization (WHO) declared in early 2020 the emergence of a new highly contagious SARS-CoV-2 coronavirus responsible for a global public health emergency. In France, the first cases of contamination have been reported since the end of January 2020, and the first death in mid-February 2020. Then, data published by Public Healh France reported an increasing and rapidly exponential number of contaminations. First cases have been identified on a cluster mode, then rapidly spreading in some French departments and regions, indicating rapid kinetics of virus spread. Given the magnitude of the situation both French territory and neighboring European territories (mainly Italy), the government mobilized the entire health system to critically manage this epidemic. This exceptional and unprecedented pandemic deeply impacted the health structures, disrupting healthcare organizations. All caregivers, including all student nurses, actively participated in the mobilization and strengthening of care teams. The health crisis exposed the population of caregivers to potentially traumatic events which can have major repercussions on their health state. The description and identification of the risk factors of the occurrence of post traumatic stress disorders in student nurses during the health crisis would allow to provide avenues for improving training devices and to facilitate health workers access to specific psychological care particularly dedicated to the student nurses population needs.

Background: COVID-19 virus infection differs among people. Some people have no or mild symptoms. For others, COVID-19 is life threatening and causes damage to the body s organs. Researchers want to better understand the virus to learn how to kill it. Objective: To understand how the COVID-19 virus causes wide differences in how sick one can become from the infection. Eligibility: People ages 18-80 with COVID-19 infection Design: Participants will be screened with a review of their medical records. Participants who enter the study at the beginning of their COVID-19 infection will stay in the hospital until they are healthy enough to go home. Those who enter after they have recovered may need to stay in the hospital 1-2 nights to perform the study tests. Participants will have MRI and CT scans of the brain, heart, and lungs. They will lie in a machine that takes pictures of the body. For the MRI, soft padding or a coil will be placed around their head and chest. They may receive a dye injected into a vein. Participants will have an ultrasound of the kidneys and heart. Participants will provide blood and urine samples. They will provide nasal swabs. Participants will have a bronchoscopy. A thin tube will be placed through the nose or mouth into the airway. Saltwater will be squirted into the lungs and removed by suction. Participants may provide a spinal fluid sample. A needle injected into the spinal canal will obtain fluid. Participants will have lung and heart function tests. At various points after recovery, participants will repeat many of these tests.

The COVID-19 pandemic is a traumatic event which could lead to a greater risk of developing post-traumatic stress disorder, especially in cancer patients who feel more at risk of contracting the virus, and fear developing serious symptoms. The study's primary objective is to measure the presence of a potential post-traumatic stress disorder in cancer patients, and to assess the associated factors. The secondary objectives are to measure patients' anxiety, as well as their perception of both the management of their cancer care, and their fear of a cancer recurrence. It is a prospective, multi-centric study using self-assessing survey offered to cancer patients currently under ongoing care or treatment. The surveys will be sent by post at the beginning of the study, and again 6 months later. Expecting a participation rate of 40%, 4000 patients will be contacted, over a period of 3 months, in order to receive 1600 responses, and 640 responses 6 months later. Researching the factors associated with the appearance of post-traumatic stress could lead to better screening of patient disorders in highly anxiety-provoking crisis situations. As a result, it would lead to an improvement of their care, healthcare organization, and their follow-up in the case of a new epidemic or any other stressful event of this magnitude. Furthermore, promoting the patient's expression capabilities favors their implication in their care, and facilitates the development of health democracy.

Primary Objective: To determine the maximum tolerated dose (MTD) of SAR442257 administered as a single agent in patients with relapsed and refractory multiple myeloma (RRMM) and relapsed and refractory non-Hodgkin lymphoma (RR-NHL), and determine the recommended Phase 2 dose (RP2D) Secondary Objectives: - To characterize the safety profile of SAR442257 - To characterize the pharmacokinetics (PK) profile of SAR442257 - To evaluate the potential immunogenicity of SAR442257 - To assess preliminary evidence of antitumor activity

This is a multi-centered, retrospective, observational study aimed at observing the current status of the management of gastrointestinal surgery during the COVID-19 pandemic, particularly the changes on surgery protocols and other key aspects of surgical workflow, so as to share experience with colleagues both domestic and abroad.

Study Objective: To test if early preemptive hydroxychloroquine therapy can prevent disease progression in persons with known symptomatic COVID-19 disease, decreasing hospitalizations and symptom severity.

The medical and paramedical staff of the front-line services are potentially exposed to SARS-CoV-2. Therefore, despite the application of standard protective measures, it is possible that a certain number of these personnel have already contracted SARS-CoV-2, including in its asymptomatic form. Serological testing in this context would be useful for deploying immune healthcare workers as to limit the risk of viral infection and transmission. Therefore, it is of utmost importance to prove that the serological response entails the production of neutralizing antibodies.

The purpose of this study assess the efficacy and safety of anti-SARS-CoV-2 convalescent plasma in hospitalized patients with acute respiratory symptoms up to 14 days after the onset of initial symptoms.
