Active clinical trials for "COVID-19"

This is a phase 2b prospective, randomized, single-blind, controlled trial of a single subcutaneous injection of peginterferon lambda-1a versus placebo for prevention of SARS-CoV-2 infection in non-hospitalized participants at high risk for infection due to household exposure to an individual with coronavirus disease (COVID-19). The study will also evaluate the regimens participants with asymptomatic SARS-CoV-2 infection detected at study entry. All participants will be followed for up to 12 weeks.

this study adopted a cross-sectional study, collected the medical history and symptoms of patients infected with Covid-19 through a questionnaire survey, and made statistical analysis, so as to provide better clinical guidance.

Sarcopenia is a risk factor for adverse outcome in critically ill patients. Sarcopenia might be estimated from muscle surface measure on tomodensitometry. The purpose of the study is to identify if muscle surfaces measured on thoracic tomodensitometry are associated with mortality in patients with acute respiratory distress syndrome due to SARS-Cov-2.

To identify the pattern of presentation of COVID-19 in patients with chronic respiratory diseases To asses the severity of COVID-19 in patients with chronic respiratory diseases To identify the outcome of COVID-19 in patients with chronic respiratory diseases

This study is to clarify the clinical characteristics of severe and critical COVID-19 from March 1st ,2022 to June 9th, 2022 in Shanghai and to explore the relationship between the characteristics and prognosis in these patients.

The purpose of this study is to investigate the correlation of intention to receive COVID-19 vaccine, recommendation behavior, and 5C psychological antecedents among Nurses. The results can be used to assist suggestions in the health education provided by nurses on the topic of COVID-19 pneumonia and its vaccination. The purpose of the study is also wants to build a basis for future research and public support in vaccine decision-making, as well as to enhance the promotion of vaccine policy and enhance the resilience of the whole population during the pandemic ear.

aim of the research is to detect hematological abnormalities in covid 19 patients and its correlation with the severity and outcome of the disease.

Estimating and recording the rate of occurrence of pulmonary and cardiovascular complications during the perioperative period in patients with past covid infection

The main objective of this research is to identify and characterize the different molecular variants of SARS-CoV-2, emerging and / or circulating in several countries of Sub-Saharan Africa (Burkina Faso, Côte d'Ivoire, Gabon, Mali, Chad and Republic of Congo) and determine their role in the evolution of the pandemic.

This study is the second cross-sectional study conducted in the region. In the first cross sectional study, conducted in the winter of 2020, we aimed to estimate the seroprevalence of SARS-CoV-2 IgG antibodies among blood donors in Sarajevo Canton. We also assessed immune durability among seropositive participants after 6 months. In total, of 1015 blood donors aged 18-65 years in Sarajevo Canton between 2 November and 3 December 2020 were recruited and population-weighted seroprevalence in Sarajevo Canton was 19.2% (95% CI: 16.7-21.6%). The aim of this second cross-sectional study is to measure the seroprevalence SARS-CoV-2 antibodies and assess antibody kinetics in the blood donor population after 12 months.
