Active clinical trials for "Coronavirus Infections"

This is a randomised controlled experiment in the form of a web based survey study which randomly exposes participants to different forms of public health messages, after which participants will be assessed on their intent to take up the COVID-19 vaccine, recommend the vaccine, and also willingness to propagate the exposed message.

Observational program, double-blind, placebo-controlled to study the preventive efficacy of the BiVac polio (Oral polio vaccine, divalent, live attenuated of types 1 and 3 vaccine against the incidence of acute respiratory infections, including COVID-19

Popular topic:Clinical trials of the consistency and non-inferiority bridging between batches of recombinant new coronavirus vaccine (CHO cells) Research purpose:Main purpose:1)To evaluate the interbatch consistency of immunogenicity of three batches of recombinant Novel Coronavirus vaccine (CHO cells) following process validation in 18-59 year olds. 2)To evaluate the non-inferiority of immunogenicity of recombinant Novel Coronavirus vaccine (CHO cells) from the combined batch and pilot scale batch after process validation in 18-59 years of age. Secondary purpose:1)To evaluate the safety of each batch of recombinant Novel Coronavirus vaccine (CHO cells) in patients aged 18-59 years.2)To evaluate the non-inferiority of immunogenicity of recombinant Novel Coronavirus vaccine (CHO cells) from the combined batch and commercial batch after process validation in 18-59 years of age. Overall design:This trial adopts a randomized, double-blind, parallel controlled trial design. Study population:The study involved people aged 18-59. Test groups:A total of 1680 subjects were enrolled in this clinical trial and randomly divided into 4 groups at 1:1:1:1 (pilot scale batch: process verification batch 1: process verification batch 2: process verification batch 3) , 420 cases per group.

Coronavirus disease 2019 (COVID-19) can cause variable symptoms ranging from mild common cold-like symptoms to severe life threatening pneumonia. Recent studies show severe outcomes of COVID-19 patients specially in males who suffer from androgenetic alopecia, would be significant and is of particular interest of this study and could help further support the hypothesis that anti-androgen therapy might represents an additional potential intervention against severe COVID-19.

Coronavac, one of the vaccines developed within the scope of combating the COVID-19 pandemic that has surrounded the world for a year, started to be applied in the first healthcare workers in our country. In this important step taken to end the pandemic, information on vaccines is still limited. Most vaccines, including the Coronavac vaccine, are applied with approval for emergency use before phase 3 studies are fully completed. While investigating the effect of the vaccine on the virus, possible side effects should also be considered. In this context, it is not known whether the vaccine has an effect on the menstrual cycle, especially of women of reproductive age. Our primary aim in our study is to evaluate the effect of the vaccine on the menstrual cycle and if the vaccine has any effect on the menstrual cycle, what kind of changes this effect causes.

The aim of this study is to analyze whether COVID-19 causes a delay in the diagnosis of gastric cancer patients particularly in the TNM staging of the tumor, or not and to compare the number of newly diagnosed patients with gastric cancer before and during the COVID-19 pandemic period.

COVID-19 infection is the cause of the current pandemic, responsible for loss of life and disability at a rate unseen before. Among survivors, the infection may cause lasting damage, such as permanent loss of lung function. This study aims to investigate if pulmonary rehabilitation done via supportive devices may reduce or prevent lung function injury. Patients will be chosen among COVID-19 patients who require hospitalization. Patients then will be divided into two groups, those who had used said devices, and compare them to those who had not used them for any reason. After a month, two groups will be evaluated by respiratory function tests, which are expected to provide the results required for a proper comparison. Pulmonary rehabilitation provided by the supportive devices is expected to either lessen or eliminate a loss of pulmonary function over time, compared to the group who did not use them.

The effects of Coronavirus Disease (COVID-19), a multisystem disease, on the body system and functions are being investigated all over the world. Examining the effect of exercise capacity, which is an important marker of cardiovascular risk in young individuals with COVID-19, will allow the planning of exercise and physical activity programs according to the needs of that specific population. The objectives of this project are:(1) To compare the submaximal and maximal exercise capacity of young adults aged between 18-30 who have had COVID-19 with healthy individuals in the same age group (2) To determine the roles of muscle strength, respiratory functions, fatigue, dyspnea, and physical activity level on exercise capacity evaluated by two different tests in young adults survived from COVID-19.

Clinical trials of prevention modalities for Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection and coronavirus disease (COVID-19) and pneumonia are underway under separate protocol(s) for close contacts (i.e., household contacts, [e.g.,3502]) of infectious (index) individuals (3502-01). Characterizing the index individuals within households will ascertain the risk of exposure for the contact participant. These data will be used to strengthen the precision of efficacy estimates. This ancillary observational study will assess the cofactors for infectiousness among index individuals whose close contacts are enrolled in COVID-19 prevention clinical trials. Additionally, this study will assess post-acute sequelae of SARS-CoV-2 infection in index individuals that are more than two weeks past their initial diagnosis.

An outbreak of Corona virus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-coV-2) occurred in Wuhan city, Hubei province, China in December 2019. Pulmonary health has been the main focus of studies of COVID-19, current articles show that cutaneous signs appear in COVID-19 patients, their identification may be vital to early diagnosis and lead to possible better prognosis in COVID-19 patients
