Active clinical trials for "COVID-19"

The impact of the COVID-19 pandemic has heavily influenced routine medical care. In the first months of the pandemic, healthcare authorities restricted medical care to emergency procedures, postponing elective surgical activity. Conversely, screening programmes and planned examinations have been temporarily suspended or delayed. Gradually, elective surgery and clinical activities have resumed, thanks to the weakening of the pandemic, to a better organization of the healthcare systems and to the diffusion of COVID-19 vaccines. In the present study, we aim to evaluate the impact of the COVID-19 pandemic on surgery for thyroid carcinoma. Particularly, we aim to investigate whether the delay in operations, screening programmes, and planned examinations for patients under follow-up after thyroid surgery have led to an increased number of aggressive tumours. To evaluate this aspect, we aim to compare the patients who had undergone thyroidectomy for thyroid cancer before the COVID-19 pandemic (from February 2019 to February 2020), during the first phase of the pandemic (from March 2020 to September 2020), and after the first phase of the COVID-19 pandemic (from October 2020 to October 2021).

This study will target Madison Metropolitan School District (MMSD) school children ages 4-19 and staff who have not had a previous positive COVID-19 test within the past 3 months. It will enroll children and adults for 1-3 days to explore whether serial "at-home" BinaxNOW testing is feasible and non-inferior to "at school" single PCR testing for the evaluation of symptomatic individuals with a negative initial BinaxNOW. It will also explore whether lollipop swabs are more acceptable and perform as well as nasal swabs with polymerase chain reaction (PCR) testing.

The next phase of the COVID-19 pandemic is likely to see a surge in an associated chronic cardiopulmonary disease that will challenge health systems. Recovered patients are presenting with persistent dyspnea at the Duke Pulmonary Post-COVID clinic. Evidence is now mounting that recovered patients have significant residual pulmonary disease, while myocardial injury has also been increasingly reported. To optimally care for these patients, Duke Pulmonary study team must comprehensively assess and monitor the changes in cardiopulmonary function and relate the changes to physiologic and quality of life outcomes. The study team will deploy cutting-edge MRI to fully characterize cardiopulmonary function in enrolled 30 subjects (accrual 23 subjects) at time point 60-120 days post recovery and 6-9 months later. Cardiac MRI will assess the myocardial status and right ventricular function, while hyperpolarized 129Xe MRI will provide a 3D assessment of pulmonary ventilation, interstitial barrier integrity, and pulmonary vascular hemodynamics. The overall objective outlined in this study is to demonstrate the feasibility and value of comprehensive longitudinal imaging characterization of cardiopulmonary structure and function in patients recovered from Covid-19.

The investigators will carry out a randomised trial of free face mask distribution in Stovner District, Oslo, Norway. Ten grocery stores will serve as study sites. Over three weeks the stores will be randomised daily to having "corona hosts" outside their entrance, handing out face masks to customers. The investigators will compare the proportion of customers who wear face masks as they enter the store in stores with or without face mask distribution.

The objective is to demonstrate if there is no increase in the risk of Sars-Cov-2 salivary carriage 7 days after a concert in the group participating in the event compared to a non participating group who stayed at home. The hypothesis is that a systematic screening of Sars-Cov-2 within the 3 days before the event allows to control the risk of transmission and prevent cluster of transmission during the concert.

This study evaluates the feasibility of an early occupational therapy (OT) protocol in critical adult patients requiring mechanical ventilation with Covid-19.

CORONAVIT is an open-label, phase 3, randomised clinical trial testing whether implementation of a test-and-treat approach to correction of sub-optimal vitamin D status results in reduced risk and/or severity of COVID-19 and other acute respiratory infections.

Originally, the study was planned to include two parts, i.e., Part A and Part B, however Part B was skipped due to changes in the overall clinical development plan. The conducted Part A was a dose-finding part to investigate the optimal dose, allowing dose adjustments upwards and downwards in younger participants. Doses tested in older participants were chosen based on acceptability of dosing in younger participants.

Electronic-nose had been used to diagnose other infectious lung diseases, such as tuberculosis. Universitas Gadjah Mada has developed an electronic-nose device which is easy-to-use, portable, and can be manufactured at a low price. Here the investigators test the electronic-nose to diagnose COVID-19 in Indonesia.

This study will compare two drugs (hydroxychloroquine and azithromycin) to see if hydroxychloroquine is better than azithromycin in treating outpatients with suspected or confirmed COVID-19.
