Active clinical trials for "COVID-19"

On January 30, 2020, the WHO declared COVID-19 a global health emergency. Children were affected with less severe forms. Niger had implemented measures in a context where children are a source of contamination. The objective was to determine the factors associated with COVID-19 in children in Niger from February to August 2020 through an analysis of the national database.

Aim of the study is to find the prevalence of thrombophilic gene methylene tetrahydrofolate reductase (MTHFR) gene polymorphism in a sample of COVID-19 patients, aiming at early detection of MTHFR mutant patients and guiding preventive therapy.

SARS-COV-2 infection reframed medical knowledge in many aspects, yet there is still a lot to be discovered. our aim is to evaluate neurological impact of covid-19; if there is any.

PRactice of Ventilation and Adjunctive Therapies in COVID-19 Patients. An observational study of ventilation practice and adjunctive therapies in critically ill, invasively ventilated COVID-19 patients during the first and second surge of COVID-19 in the Netherlands.

The aim of this study is to evaluate the protective measures and awareness of dentists working in Turkey regarding the COVID-19 pandemic.

In the retrospective case series, consecutive COVID-19 patients admitted from June 1 to December 31, 2020, were analyzed. A 1:1 matched cohort was created by propensity score-matched analysis. Demographic data, laboratory findings, comorbidities, treatments, and in-hospital outcomes were collected and compared between COVID-19 patients with and without statin use.

Determine the consequences of COVID-19 pandemic on routine targeted surgeries. Five surgical procedures were considered : cataract surgery, hip and knee arthoplasties, coronary revascularisation by angioplasty and definitive cardiac stimulation. The objective of the study is to quantify changes of these procedures in 2020 and in 2021 (up to June) compared to 2019 taking into account their annual evolution and according to the type of operation (primary or reoperation/revision) and emergency status, if applicable.

This is an observational cross sectional study included 202 patients diagnosed to have COVID-19. The study was conducted at Zagazig University Isolation Hospitals from the period of March 2020 to June 2021. The study was approved by Zagazig University Ethics Committee (number 9229). A written informed consent was obtained from all participants. Inclusion criteria: The study includes laboratory confirmed COVID-19 patients (confirmed by real-time polymerase chain reaction) admitted l during the period of the study. The patients were classified into two groups, group A included mild/moderate cases, group B included severe/critical cases according to the following criteria. Severity of COVID-19 was graded as follows: mild; mild clinical symptoms, no pneumonia on lung CT; moderate: fever, cough and lung CT with pneumonia; severe: respiratory distress (respiratory rate > 30 /min, oxygen saturation (O2Sat) ≤ 93 percent at rest and/or ratio of arterial oxygen partial pressure to fractional inspired oxygen ≤300 mmHg (PaO2/FIO2); and critical: aforementioned criteria of respiratory failure receiving mechanical ventilation, shock, and/or organ failure other than lung and/or intensive care unit (ICU) hospitalization. All participants were subjected to full history taking including smoking history and comorbidity profile. Clinical symptoms including: fever, cough, dyspnea, myalgia, hemoptysis, sore throat, diarrhea, loss of smell and anorexia were recorded. Radiological assessment by initial chest x ray then CT chest as possible and appropriate. Routine laboratory investigations: Complete blood count (CBC), coagulation profile, serum biochemical tests (including renal and liver function, and electrolytes), laboratory investigation to assess severity of COVID-19: lactate dehydrogenase (LDH), myocardial enzymes (CPK-MB), serum ferritin, D dimer and arterial blood gases analysis. Patients were followed up for the need for ICU and mechanical ventilation (MV), duration till conversion, total length of stay and final outcome whether survived or died were recorded.

The investigators hypothesize that early mobility condition and muscle power may be the predictive factors for Coronavirus disease 2019(COVID-19) patients' activity prognosis and hospitalization days. To prove our hypothesis, the investigators proposed a retrospective cohort study to see if ICU mobility scale(ICUMS) and Medical Research Council Sum Score(MRCSS) can predicted the patients' Barthel index after discharge and hospitalization days.

The study assesses the efficacy and safety of administration of hyperimmune plasma in hospitalized COVID-19 patients. Efficacy was measured as 28-day mortality following convalescent plasma transfusion. Safety was measured as the rate of adverse reactions. to plasma infusion.
