Active clinical trials for "COVID-19"

Multisystem inflammatory syndrome in children (MIS-C) is a rare severe complication to SARS-CoV-2 infection in children. It has been reported to occur in approximately one of 3,000 to 4,000 unvaccinated children during the COVID-19 waves dominated by variant Alpha of SARS-CoV-2. However, the incidences following SARS-CoV-2 infection with variant delta and omicron, as well as among vaccinated children and adolescents with SARS-CoV-2 is yet unexplored. The investigators aim to estimate the incidence of MIS-C and in vaccinated and unvaccinated children and adolescents following variants delta and omicron, and other complications of SARS-CoV-2 including complication due to SARS-CoV-2 lock-down, based on a nationwide prospective population-based cohort study.

The coronavirus disease 2019 (COVID-19) caused by the infection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)，resulting in more than 82 million confirmed cases and caused around 1.8 million deaths, as of 2 January 2021. The ongoing pandemic still poses unprecedented global threat to public health system worldwide. On December 31, 2020, the joint prevention and control agency of China Council announced that Sinopharm SARS-CoV-2 inactivated vaccine had been conditionally approved by National Medical Products Administration, and the protection rate was 79.34%. So far, more than 198 vaccines were currently in preclinical or clinical development. The investigators aimed to initiate an observational cohort of healthy individuals injected with SARS-CoV-2 Vaccine, which will perform a longitudinal, comprehensive analysis of the SARS-CoV-2 vaccine Induced adaptive immune responses.

The purpose of this study is to monitor short-term changes in tissue oxygen saturation and local blood flow as results of changing from supine to prone position in ARDS COVID-19 patients

The main overarching aim of this study is to build a research clinic, as part of the NoRCoRP platform covering Nottingham and Nottinghamshire to facilitate learning and research in the whole population of patients who have had COVID-19.

The aim of this study is to confirm or rule out the residual presence and viability of SARS- CoV-2 in the respiratory tract and lung parenchyma of patients previously infected with SARS-CoV-2. Presence and viability of SARS-CoV-2 in lung tissue will be assessed with reverse transcriptase-polymerase chain reaction (PCR) and viral culture. The histological location of residual SARS-CoV-2 will be determined with fluorescence immunohistochemistry and single molecule fluorescence in situ hybridization, targeting viral proteins and RNA respectively.

For the last years, studies have described the " Post-intensive care Syndrome " (PICS), which consists in alteration of quality of life, cognition, autonomy and psychological disorders within the months after intensive-care. Patients with COVID-19 in intensive care units are at high risks to develop PICS. The primary objective is to analyse the incidence of the post-traumatic stress disorder at 12 months after intensive-care for a COVID-19 Acute Respiratory Distress Syndrome (ARDS).

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes coronavirus disease 2019 (COVID-19). The global outbreak of COVID-19 is a major public health problem. COVID-19 causes a wide range of symptoms. These symptoms range from mild breathing problems to life-threatening problems or death. Some people have no symptoms. This study aims to learn how acute and late immune responses to COVID-19 lead to different outcomes. The immune system is the body s defense against germs, including viruses, that invade the body. Objective: To characterize the immune responses during and after SARS-CoV-2 infection and determine if there is any relationship to clinical course and outcome. Eligibility: People ages 0 99 who have confirmed or suspected SARS-CoV-2 infection, people who are not infected despite heavy exposure, and relatives of enrolled participants. Design: This is a sample collection protocol to receive send-in biological specimens for exploratory studies, including gene testing. Participants will not be seen at the NIH for study visits. Study staff will talk with participants health care providers to screen them for the study. Participants enrolled into the protocol will send samples and clinical information at least once and more often if the participant has COVID-19. All participants will provide blood samples and possibly stool. We may also ask for left over specimens from any medical procedures completed as part of medical care. The study staff will also request participants health care providers to complete a survey to collect demographic and medical data. Some of this information may need to be provided directly by the participant. Pregnant individuals are invited to participate and may be asked to give cord blood samples after delivery. Study findings that affect participants health may be shared with their health care provider. Depending on findings, participants may be contacted to take part in other NIH studies.

The non-essential and non-urgent follow-up consultations of patients living with HIV were postponed or transformed into "teleconsultation" or exchanges of e-mails between practitioners and patients during COVID-19 epidemic. This change in care can have an impact on follow-up and access to treatment for PVVIH.

The Cooper vitamin D3 study is a randomized study investigating whether daily vitamin D3 supplementation can prevent respiratory tract infections, influenza-like illness and covid-19 in hospital workers.

This project will address key testing challenges in Utah schools by building on collaborations with public school districts, private schools, charter schools and with Utah Department of Health on coronavirus disease (COVID-19) testing and existing infrastructure. The study team will work closely with schools and the Utah public health system to implement and test a shovel-ready and scalable health information technology approach that delivers automated text messages (TM) to students' parents and faculty/staff members around COVID-19 testing. In addition, some students and faculty/staff will receive a health navigator (HN) follow-up to ensure that tests are completed. Families (both of students and faculty/staff members) will be offered the recently FDA-approved in-home serial testing approach if accessing in-person testing is a challenge. While this project is focused on COVID-19 testing, in the case that the COVID-19 vaccination becomes more relevant or is the priority of the school, the study team is able to tailor the intervention to focus on the vaccine as well.
