Filter by:This before-and-after study aims to evaluate the usefulness and efficacy of a personalized computerized cognitive training (CCT) to improve cognitive function among people with post-acute sequelae of COVID-19 (PASC).
This study is a non-randomized observation and comparison of immune response between bacteriologically confirmed TB patients under treatment cohort who received COVID-19 vaccine (n=54) vs healthy individuals (n=54). Each participant will receive single or double doses of one of COVID-19 vaccines (Pfizer-BioNTech COVID-19 vaccine, AstraZeneca vaccine or Janssen Ad26.COV2.S COVID-19 vaccine) in the deltoid muscle of the non-dominant arm. Study Duration approximately 1 year. The main focus of this study is to compare the humoral and cellular immunological responses of the COVID-19 vaccines between bacteriologically confirmed TB patients under treatment vs healthy individuals. This study is funded by the Wellcome Trust. The grant reference number is 220211/A/20/Z.
A single COVID-19 booster dose has been recommended in the United States for adolescents aged ≥12 years to enhance protection against SARS-CoV-2 infection. This study will assess the efficacy of a one-time reminder/recall for COVID-19 booster dose among eligible adolescents in a regional healthcare system.
COVID-19 infection during pregnancy is associated with increased risk of pre-eclampsia, preterm birth and stillbirth. Pregnant people with COVID-19 have a higher rate of ICU admission and intubation than those who are not pregnant. COVID-19 vaccine is recommended before pregnancy and during pregnancy to decrease these risks. Despite the benefits of COVID-19 vaccination, only 71% of pregnant women were vaccinated for COVID-19 as of June 2022 (most prior to pregnancy), with a much lower rate of 58% among non-Hispanic Black women. An effective intervention is needed to improve COVID vaccination rates for pregnant people overall. In this study, the investigators will perform a randomized controlled trial aimed at practice change in obstetricians' offices, with an overall goal of increasing maternal COVID-19 vaccination rates.
An AstraZeneca-sponsored observational, electronic healthcare record (EHR)-embedded retrospective cohort study to assess the real-world effectiveness of EVUSHELD against SARS-CoV-2 infection, COVID-19-related hospitalization, and other COVID-19 related outcomes in the total EUA-eligible patient population treated in DoD Health system.
This trial is a clinical study to evaluate the safety of sequential boosters of novel coronavirus mRNA vaccine in adults aged 18 years and older who have completed three doses of novel inactivated coronavirus vaccination. According to the results of the previous phase I clinical trial, the incidence of adverse reactions in the 0.3 ml dose group was lower than that in the 0.5 ml dose group, and the degree of adverse reactions was weaker. The dose of 0.3ml was chosen for the current study, and a 1-dose immunization program was completed for safety observation.
The purpose of this study is to learn about the safety and effects of nirmatrelvir/ritonavir for the potential treatment of COVID-19 rebound. The study is seeking participants who: - Have completed treatment with nirmatrelvir/ritonavir - Have a rebound in COVID-19 symptoms - Are SARS-CoV-2 (COVID-19) positive All study medications will be taken 2 times a day by mouth for 5 days. The first dose of study medication is taken at the study clinic and the rest at home. We will examine the experiences of people receiving the study medicines to those who do not. This will help us determine if the study medicines are safe and effective. People taking part will be in this study for about 24 weeks. Enrolled participants will need to visit the study clinic at least 8 times during the study.
The rate of nosocomial SARS-CoV2 infections found in the different studies since the beginning of the pandemic is very variable (<1% in hospitals in the USA to about 20% in a British hospital). Mortality related to these nosocomial SARS-CoV2 infections is higher than in the general population. The risk factors identified for this nosocomial acquisition are multiple. We were confronted with nosocomial acquisitions and cluster situations in the services, without exhaustive data to measure these phenomena, and we lacked data to consider areas for improvement. The objectives of this study are to determine the proportion of nosocomial SARS COV 2 infections in the total number of patients hospitalized with a Covid-19 infection at the CHR Metz-Thionville in 2021, and to describe the characteristics of this population.
The aim of the study is to characterize and to quantify SARS-CoV-2 strains in stools, in comparison with the viral strains in respiratory samples, from patients hospitalized for COVID-19. The methods will be standard ddPCR quantifying SARS-CoV-2 RNA and next generation sequencing-whole genome sequencing. The expected results will allow us to better understand SARS-CoV-2 dynamics and compartmentalization, both in the respiratory tract and in digestive-related tissues, according to the evolution of SARS-CoV-2 variants.
The primary objectives of this study are to establish exercise training as a novel intervention to treat Long COVID and characterize the cardiorespiratory and autonomic physiology in these patients to precisely characterize mechanisms contributing to this syndrome.
