Active clinical trials for "COVID-19"

Introduction: The SARS-Cov-2 outbreak in France and the concomitant massive increase in the number of cases requiring hospital management create a major risk of COVID-19 infection for hospital staff. In addition to nosocomial transmission, the health care workers (HCWs), defined as persons serving in health care settings who have the potential for direct or indirect exposure to patients or infectious materials, are also exposed to community transmission. Whether HCWs acquire infection at work or in the community is important to adapt protection measures. A few studies investigated COVID-19 infection among medical and nursing personnel. However, none have analyzed all categories of hospital staff. As of April 9, 2020, a total of 9,282 US HCWs with confirmed COVID-19 had been reported to CDC (US), however description of occupational activities was not available. Therefore, limited information is available about COVID-19 infection among HCWs. Thus, the objectives of the sdudy are to estimate the incidence of symptomatic SARS-CoV-2 infection in HCWs in five university hospitals (including geriatric hospitals) of the great Paris area and to estimate both nosocomial and community risk factors. Method: A prospective and retrospective cohort study that includes all hospital staff (including medical and nursing personnel, health care managers, laboratory, radiology, reception staffs, stretcher-bearers, etc.) working in different departments of five university hospitals (acute medical centers and geriatric hospitals) in the great Paris area (9 000 HCWs). Incidence of symptomatic SARS-CoV-2 infection will be estimated with its 95%CI. Individual and contextual risk factors will be analyzed using multilevel multivariate logistic regression modelling to account for clustering and confounding. Conclusion This study should make it possible to better characterize SARS-Cov-2 contamination of HCWs and to estimate the share of nosocomial transmission.

This study aims to investigate outcomes and predictors of outcome after extracorporeal membrane oxygenation (ECMO) therapy for severe acute respiratory syndrome (ARDS) in COVID-19 patients.

The overall goal is to study the immune response to SARS-CoV-2 infection over the period of one year in the blood of a representative cohort of ETH students/employees.

The hospitalization of a patient in intensive care is a traumatic experience for his family members. With the current COVID-19 epidemic, in view of the high risk of contamination, drastic measures to limit the transmission are necessary, with the creation of spaces dedicated to the care of Covid+ patients, and family are not allowed to visit. At the Strasbourg University Hospital, visits were prohibited from the start of the epidemic. Information concerning the patient's state of health is therefore delivered to families by telephone, on call by the healthcare team only, every day before 6 p.m. or in the event of a serious event at any time. The primary purpose of this project is to assess the psychological impact of the hospitalization of a loved one in intensive care for Covid-19 infection at 3 months post-hospitalization, in a context of pandemic with ban on visits.

In severe COVID-19 pulmonary failure, the profound hypoxemia is mainly related to pulmonary vasodilation with altered hypoxic pulmonary vasoconstriction (HPV). Besides prone positioning, other non-ventilatory strategies may reduce the intrapulmonary shunt. This study has investigated almitrine, a pharmacological option used in standard care to improve oxygenation. A case control series of mechanically ventilated confirmed COVID-19 patients was recorded. At stable ventilatory settings, consecutive patients received two doses of almitrine (4 and 12 mcg/kg/min) at 30-45 min interval each, and were compared to 7 "control" COVID-matched patients conventionally treated. The end-point was the reduction of intra-pulmonary shunt, with an increase in partial pressure of arterial oxygen (PaO2) and central venous oxygen saturation (ScvO2).

The purpose of this study is to perform a secondary analysis of pre-existing de-identified limited datasets obtained from sites participating in Tier 1 (STUDY20040154: Neurologic Manifestations of COVID 19 in Children) and Tier 2 (STUDY20040278: Neuro COVID - Outcomes). The data will be used to determine the prevalence and severity of neurological symptoms among patients requiring critical care admission for confirmed or suspected novel coronavirus (COVID-19) and to determine the predictors for limitation of care in the study population, as well as, the prognosis of neurologically injured patients admitted to the ICU during the COVID-19 crisis. This study is sponsored by the Pediatric Neurocritical Care Research Group (PNCRG) and sponsored and funded in part by the Neurocritical Care Society.

CON-VINCE (COvid-19 National survey for assessing VIral spread by Non-affected CarriErs) is a national, monocentric, and longitudinal study aiming to evaluate the spread dynamics of the COVID-19 disease within the Luxembourgish population. Participants who are clinically asymptomatic or present with only mild symptoms will be followed up longitudinally, regularly tested for SARS-CoV-2 by RT-PCR, antibody status, and subjected to an epidemiological, clinical and biological phenotyping to better understand the nature, dynamics of infectivity and spread of the virus in the population. CON-VINCE will also track the psychological and socio-economic impact of long-term containment measures on the general population.

This is a protocol-driven observational study of lung ultrasound and focused echocardiography images obtained in the Emergency Department (ED) and Intensive Care Unit (ICU) settings as a part of existing standard of care. The objectives of this study are as follows: To characterize various clinical and cardiopulmonary ultrasound findings and describe their relationship with the clinical course of patients with COVID-19 in the ED and ICU. To describe, develop, and validate a prediction tool that can accurately predict the need for invasive mechanical ventilation (IMV) and acute respiratory failure in COVID-19 patients using clinical, laboratory, and ultrasound data.

Mortality rates caused by SARS CoV-2 differ between countries and this difference might be explained by several reasons. Childhood vaccination rate is thought to be one of them. Therefore present study aimed to examine the possible relationship between DTaP (diphtheria, tetanus, pertussis) and measles vaccination rates of Organization for Economic Co-operation and Development (OECD) countries and case fatality rate (CFR) caused by SARS CoV-2.

This study will study the potential utility of the Quantra QPlus System in patients inflicted with COVID-19 disease.
