Active clinical trials for "COVID-19"

Among the distinctive features of Covid-19, numerous reports have stressed the importance of vascular damages associated with coagulopathy onset. Microparticles (MPs) shed by apoptotic/stimulated cells are reliable markers of vascular damage released upon pro-inflammatory conditions and behave as active participants in the early steps of clot formation. In addition, MPs carry ACE1 and ACE2, the cell-entry receptor for SARS-Cov2 in the vasculature and up-regulate ACE1 expression in neighbouring endothelial cells. This may contribute to unopposed angiotensin II accumulation which further exacerbate tissue injury and promote both inflammation and thrombosis. The aim of the study is to evaluate the impact of circulating MPs on ACE2 expression, the cell-entry receptor for SARS-Cov2 on endothelial cells.

During COVID-19 epidemic, hydroxychloroquine was proposed and authorized as a possible key agent in the treatment of COVID-19 hospitalized pneumonia, including in France. Gautret et al. proposed the combination regimen with azithromycin. However only one study reported the interest of azithromycin alone. Retrospective study reporting the impact of the anti-infective agents used during the pandemic in a tertiary care hospital, using azithromycin with or without hydroxychloroquine.

In a case-series analysis, up to 20 patients undergoing elective or urgent/emergent surgery that are COVID-19 positive will be approached for patient consent. OR PathTrac (RDB Bioinformatics, Omaha, NE 68154) collection kits will be utilized for sampling of 48 sampled time/locations per patient. Patient sampling locations will include the nasopharynx and oropharynx. Operating room environmental locations will include areas in the patient care arena such as the anesthesia machine. Samples of each location will be obtained before and after treatment with UV-C (Helios, Surfacide), germicidal, ultraviolet light and other infection control practices that are currently in place, such as utilization of preoperative chlorhexidine wipes, nasal iodine, improved hand hygiene, and improved vascular care. UV-C light for environmental cleaning is not regulated by the FDA. Samples will be processed by RT-PCR for presence of SARS-CoV-2 nucleic acid. Positive samples will be sent to Dr. Stanley Perlman's lab to assess viability. Samples will also be assessed for S. aureus as a process control. We will characterize the epidemiology of perioperative SARS-CoV-2 spread as a quality improvement initiative to improve our current perioperative infection control bundle and to serve as the platform for national dissemination of a perioperative COVID-19 defense strategy.

This study aims to analyze the online learning of veterinary anatomy during COVID-19 pandemic lockdown.

The prevalence and typical patterns of neurological complications in hospitalized COVID-19 patients admitted to the intensive care units of the University Hospital Zurich will be investigated. The impact of neurological complications among COVID-19 patients on mortality, functional outcome, and organizational outcomes will be analyzed.

Rationale: The clinical manifestations of SARS-CoV-2 infection in children are poorly characterized. Preliminary findings indicate that they may be atypical. There is a need to identify the spectrum of clinical presentations, predictors of severe disease (COVID-19) outcomes, and successful treatment strategies in this population. Goals: Primary - Describe and compare characteristics of confirmed SARS-CoV-2 infected children with symptomatic test-negative children. Secondary - 1) Describe and compare confirmed SARS-CoV-2 infected children with mild versus severe COVID-19 outcomes; 2) Describe healthcare resource utilization for, and outcomes of, screening and care of pediatric COVID-19 internationally, alongside regional public health policy changes. Methods: This prospective observational study will occur in 50 emergency departments across 11 countries. We will enroll 12,500 children who meet institutional screening guidelines and undergo SARS-CoV-2 testing. Data collection focuses on epidemiological risk factors, demographics, signs, symptoms, interventions, laboratory testing, imaging, and outcomes. Collection will occur at enrollment, 14 days, and 90 days. Timeline: Recruitment will last for 12 months (worst-case model) and will begin within 7-14 days of funding notification after ongoing expedited review of ethics and data sharing agreements. Impact: Results will be shared in real-time with key policymakers, enabling rapid evidence-based adaptations to pediatric case screening and management.

The objective of this study is to evaluate the clinical characteristics and outcomes of critically ill patients with COVID-19 admitted to the intensive care unit. A Multicenter Observational Study.

We hypothesized: During the COVID-19 pandemic, the sleep quality of pregnant women decreases. During the COVID-19 epidemic, the stress level of pregnant women increases. During the COVID-19 epidemic, the level of physical activity of pregnant women decreases. Aims: The aim of the study is to determine the sleep quality, stress level and physical activity level of pregnant women who maintain the home quarantine during the COVID-19 pandemic.

Aim of the study is to investigate whether the Covid-19 is found in the vaginal swab samples of female patients diagnosed with covid-19, to evaluate the presence of Covid-19 and the risk of transmission of Covid-19 by intercourse or vaginal delivery.

This study seeks to determine how COVID-19 affects the clinical outcome of patients with chronic liver disease, and whether the clinical course of COVID-19 is influenced by underlying chronic liver disease.
