Active clinical trials for "COVID-19"

This study aims to conduct formative usability and internal validation of the COVID-19 rapid diagnostic test tool based on DNA aptamers, involving 200 patients to assess aspects of experimental setup, testing center, testing kit configuration, designing algorithms or workflows for clinical trials, and also assess initial accuracy by validating with the patient's PCR test results.

Aim of the study is to evaluate the presence of SARS-CoV2 RNA in the saliva of patients with suspected or confirmed COVID-19 in order to validate the analysis of this type of sample for the diagnosis of SARS-CoV2 infections.

Since the first report of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant of concern (VOC) P.1 in Manaus, Brazil, a rapid spread of this lineage across the country has been observed. Recent studies indicate that this variant is associated with higher transmissibility; it is not known whether it is associated with clinical severity and higher mortality rates. This is a retrospective cohort study carried out at Hospital de Clínicas de Porto Alegre. Adult patients aged 18 years or more and 65 years or less who were admitted to the hospital due to symptomatic COVID-19 from June 2020 to May 2021 and had a reverse transcriptase-polymerase chain reaction (RT-PCR) cycle threshold value for either SARS-CoV-2 N1 or N2 target ≤ 25 were eligible to the study. Samples from 86 patients (43 from June 2020 to November 2020 and 43 from February 2021 to May 2021) were sequenced for further evaluation. These dates were defined since the emergence of P.1 lineage in late January. Clinical data regarding ventilatory support, date of onset of symptoms, laboratory findings and mortality were collected from each patient. This retrospective cohort aims to assess whether the number of days needed for supplementary oxygen either by noninvasive ventilation or high-flow nasal cannula from onset of symptoms differs among patients infected with the P.1 SARS-CoV-2 variant and those infected with other variants.

In Kuwait, the total number of COVID-19 confirmed cases exceeds 5000 patients. Risk factors of possible risk factors of confirmed COVID-19 infection that developed major organ dysfunction are not yet identified among patients in Kuwait. we aimed to describe the clinical characteristics of hospitalized symptomatic COVID-19 positive patients, assess possible risk factors of confirmed COVID-19 infection who developed major organ dysfunction, determine risk factors for renal dysfunction and their outcome and assess the response of critically ill patients to different therapeutic modalities.

In the context of the COVID-19 pandemic, the role of the gut microbiome is yet unknown. The aim of this trial is to evaluate the clinical contribution of the gut microbiome composition and diversity on the disease severity and to estimate the viral load in stool samples.

The scope of this study is to validate the Pine Trees Health COVID-19 Molecular Test with unique clinical specimens from across two (2) geographically diverse point-of-care testing sites in the United States. The results will be analyzed and compared against results from the CDC 2019- Novel Coronavirus (2019-nCoV) Real-Time RT-PCR Diagnostic Panel. The primary objective is to generate clinical performance data for the Pine Trees Health COVID19 molecular diagnostic test in the point-of-care setting.

Retrospective, observationnal study. Evaluation of the association between plasmatic SARS-CoV-2 RNA and day 60 mortality in ICU adult COVID-19 patients.

Severe COVID-19 prognostic factors have been studied worldwide throughout the pandemic, but there is considerable variability. Therefore, the investigators will summarize the identified prognostic factors in the international literature and will conduct a retrospective cohort study to identify the prognostic factors of severe COVID-19 in hospitalized patients of the Hospital de la Santa Creu i Sant Pau in Barcelona (Spain) between March 2020 and February 2021, compare them with those mentioned in the international literature and establish those most adequate to our population.

Investigators aimed to better understand the pathophysiology of SARS-CoV-2 pneumonia in non-critically ill hospitalized patients secondarily presenting with clinical deterioration and increase in oxygen requirement

Objectives This survey aims at reporting the immediate impact of the COVID-19 epidemic on outpatients followed in Physical and Rehabilitation Medicine (PRM). It focuses on the disruption of PRM healthcare services during the quarantine period in France between 2020 March 17th and May 11th and on its medical consequences. Method This observational study was conducted in the PRM department of a French University Hospital. Outpatients whose PRM medical consultation had been cancelled were contacted by phone between April 9th, 2020 and May 7th, 2020. A structured questionnaire was fulfilled for each patient. Demographical and medical data were recorded, including the disabling diseases motivating the PRM outpatients' follow-up. The necessity to perform an immediate phone consultation or to schedule an urgent consultation within the next 3 weeks constituted the main judgment criterion. Other recorded criteria were: the reason for this urgent need of a medical consultation, the access to other medical services during the quarantine period, the interruption of home-based rehabilitation services and its perceived consequences for the patients.
