Active clinical trials for "COVID-19"

The Therma COVID-19 Rapid Antigen Test is an in vitro rapid, lateral flow immunoassay intended for the qualitative detection of SARS-CoV-2 nucleocapsid protein antigens in human saliva specimens. This test is intended for near-patient use at the point-of-care or lay person, self-use in a non-laboratory or home setting using saliva samples from individuals with or without symptoms of COVID-19. The Therma COVID-19 Rapid Antigen Test will be compared to a Health Canada approved RT-PCR COVID-19 test. Nasopharyngeal (for RT-PCR) samples will be collected at a COVID-19 Testing centre and saliva (for the rapid antigen test) samples will be collected and compared. The prospective, observational, feasibility study will test 300 participants to establish the performance characteristics of the test on saliva specimens.

The purpose of this study is to determine whether trained medical detection dogs can accurately detect the presence of COVID-19 in people infected with the virus, or using samples of their clothing or body odour. The study will train dogs to identify and discriminate between individuals wearing clothing collected from people infected with SARS-CoV-2 and uninfected individuals under semi-field conditions.Following this training, field testing will be used to determine whether trained dogs can distinguish between people infected with SARS-CoV-2 and uninfected individuals, producing estimates of dogs' sensitivity and specificity.

Evaluating the performance of the Sofia SARS Antigen FIA

The purpose of this research project is to study small airways physiological function in patients with chronic obstructive lung disease or COVID-19 and explore the relationship with in-vivo microanatomical small airway structure as measured by OCT. Correlating endobronchial assessment with multiple breath nitrogen washout and impulse oscillometry will allow the characterisation of the relationship between small airway structural findings and these validated investigations. A small volume lung wash, endobronchial brushings and the collection of a limited number of endobronchial cryobiopsy samples will be performed to better understand the endobronchial environment of the small airways through inflammatory studies. Following the completion of any such work, residual samples will be stored in a "bio-bank" to enable the completion of future work. Understanding the relationship with symptom-based quality of life scoring questionnaires and a functional assessment of exercise capacity will help elucidate the clinical impact of in-vivo small airways findings.

All hospitalised patients with COVID-19 who have positive RT-PCR for SARS-COV-2 will be included in the study. The patients will be divided into two groups, as diabetics and non-diabetics. The COVID-19 patients' medical records will be evaluated and compared in terms of the duration of hospitalization, the presence of lung involvement in Computerised Tomography, the need for intensive care unit and mortality rates in patients with and without diabetes.

Digital misinformation has been flagged as a major risk of the 21st century, with an estimated cost of $78 billion to the global economy each year. Given this scope, we propose to characterize how misinformation is spread via messenger platforms (e.g. WhatsApp). Specifically, we seek to: Identify metrics of potential misinformation (Aim 1). This is based on the hypothesis that although message contents are highly private, proxy markers can be used to identify potential misinformation. Understand the base-rate by which misinformation is shared via messaging applications (Aim 2). This is founded on the hypothesis that misinformation is endemic on messaging platforms, and thus needs to be documented. Identify "super spreaders" responsible for sending and receiving a large volume of misinformation (Aim 3). Here, we hypothesise that a small group of super spreaders are responsible for the bulk of misinformation-sharing on messaging applications. The thrust of this work aligns with both government priorities and the grant's thematic areas, providing actionable findings that are timely amidst a worldwide surge of misinformation.

The purpose of the research is to evaluate new blood tests, which measure immunity to the COVID-19 coronavirus after vaccination. These tests will be used to measure T-cell and antibody immunity after COVID-19 vaccination. Recent studies show that less than one-fifth of chronically immunosuppressed transplant recipients developed anti-receptor-binding domain antibodies after the first dose of the Pfizer vaccine (Boyarski, 2021). ood sampling at periodic intervals. These samples will be used to measure T-cell and antibody immunity to the COVID-19 coronavirus.

The aim of the study will be to determine the epidemiological and clinical features of COVID-19 cases, immunological and virological courses, interaction with nutritional status, and response to treatment for COVID-19 patients admitted to treatment centers in Ethiopia. Methods: This multi-site cohort enrolls, patients with confirmed COVID-19 infection admitted to treatment centers will be enrolled irrespective of their symptoms and followed up for 12 months. Baseline epidemiological, clinical, laboratory and imaging data will be collected from treatment records, interviews, physical measurements and biological samples. Endline data involves treatment and prognostic outcomes to be measured using different biomarkers and clinical parameters, The patients will be followed up in the selected treatment centers for COVID-19 infection. For all data collected both descriptive and multivariable analyses will be performed to isolated determinants of the treatment outcome and prognosis to generate relevant information for informed prevention and case management.

Use of rapid serological tests to assess the vulnerability to SARS-CoV-2 infection of subjects aged 4-16 years old and cohabiting with at least one family member who tested positive to SARS-CoV-2

This project is an unfunded collaboration of approximately 30 emergency departments across Europe led by the EUSEM research network. It involves collection of data in relation to determining the epidemiology and outcome of adult patients who present to emergency departments with a suspected Covid infection.
