Case Fatalities in Hospitalised COVID-19 Patients in the UK
Covid19This study will investigate how the case fatality in hospitalised patients with COVID-19 has changed throughout the pandemic. It will also explore possible mechanisms that could be driving these changes. This analysis will enhance our understanding of the virus, which will be important for researchers and clinicians to respond appropriately.
Evolution of COVID-19 in Anticoagulated or Antiaggregated Patients (CORONA Study)
Covid19CORONA is a retrospective, observational, one center study to investigate the clinical evolution (in terms of survival and thromboembolic complications) of patients on chronic treatment with anticoagulants or antiplatelet agents who are admitted to the hospital for COVID-19 compared with patients who do not receive anticoagulants or antiplatelet agents.
SARS-CoV-2 /COVID-19 Admission Screening in a University Hospital Setting
Covid19SARS-CoV-2The proportion of asymptomatic carriers of SARS-CoV-2 remains elusive, so the potential benefit of systematic screening during the SARS-CoV-2-pandemic is controversial. We investigate the proportion of asymptomatic inpatients who were identified by systematic screening for SARS-CoV-2 upon hospital admission. Adult patients admitted to the University Hospital Basel from 01.04.-14.06.2020 were routinely tested for SARS-CoV-2 within 72 hours of admission by nasopharyngeal swabs. Each patient screened during the study period was retrospectively classified symptomatic or asymptomatic for COVID-19 based on medical chart review.
Characterizing the Immune Response and Neuronal Damage in COVID-19
SARS-CoV InfectionCovid-19The Investigators plan to study the innate and adaptive immune response, the inflammatory response, and associated complications such as complement activation and neurological damage in SARS-Cov-2 infected individuals. Patients with mild, moderate and severe COVID-19 disease will be enrolled.
MYocardial DOmmages Related to COVID-19
Covid19Non Ischemic Myocardial Injury3 moreMyocardial injury, as assessed by elevation of cardiac troponins (Tnc), is frequent among patients with COVID-19. Although rare autopsy cases reported COVID-19 related myocardial inflammation, the origin of Tnc elevation is unknown to date. Several cardiac causes, such as myocarditis, non-ischemic myocardial injury (NIMI), or myocardial infarction (MI) may lead to Tnc kinetic. Our work will test the hypothesis that during SARS-Cov2 infection, the elevation of cardiac biomarkers could be linked to the occurrence of myocarditis.
COVID-19 Seroprevalence Study in ITM Staff
Covid19In Belgium, the corona virus disease 2019 (COVID-19) epidemic is in the growing phase of its second wave. The Belgian crisis cell is balancing between allowing the economy to recover and minimize the disease spread. To decide which containment measures should be maintained, reinstalled or suspended, information on what proportion of people has been infected and on possible risk factors for virus transmission can be helpful. This study will be conducted on staff members of the ITM. All staff members will be invited to participate. Participants will be asked to have a blood sample drawn for detections of antibodies against SARS-CoV-2 (using one of these two commercial assays: Anti-SARS-CoV-2 ELISA (EUROIMMUN) or WANTAI SARS-CoV-2 Ab ELISA (WANTAI SARS-CoV-2 Diagnostics)) and to complete a questionnaire about their exposure, both within and outside the ITM, to the SARS-CoV-2, and about their health and symptoms. The primary objective is to estimate the occurrence rate of anti-SARS-CoV-2 antibodies or seroprevalence in ITM staff. Secondary objective is to estimate the SARS-CoV-2 seroprevalence in ITM staff member groups, stratified by variables obtained through the questionnaire, such as age, gender, symptoms, exposure to COVID-19 patients/samples, comorbidities, adherence to containment measures.
COVID EHR COHORT at the University of Wisconsin
COVID-19Cancer4 moreThis cohort study will obtain electronic health record (EHR) data (limited data set) from 21 health systems affiliated with the Cancer Center Cessation Initiative (C3I) network or health systems with large numbers of COVID-19 patients to explore whether smoking status, cancer history, and other risk factors among patients diagnosed with COVID-19 are associated with mortality and/or COVID-19 disease severity/complications. Each site will provide data from their health system EHR on a regular basis that includes all patients identified as having COVID-19 at some point in the interval from February 1, 2020, through January 31, 2022.
Place of Circulating Biomarkers and Respiratory Eicosanoids in the Prognosis of Severe Forms of...
CoronavirusCovid19The research is a prospective, multicentric (Groupe hospitalier Paris Saint-Joseph, Centre Hospitalier de Versailles André Mignot and Centre Hospitalier Victor Dupouy), non-interventional, prospective study. It aims at measuring eicosanoids at different stages of Covid-19 infection.
Prognostication of Recovery in Early Disorders of Consciousness After COVID-19
Covid19Coma1 moreThe primary aim of this research proposal is to use multimodal metrics (e.g., clinical data and advanced neuroimaging) in the early (i.e., acute hospitalization) phase of recovery from COVID-19-related disorders of consciousness to predict outcome at 3, 6, and 12 months post-hospitalization. We aim to construct an algorithm that synthesizes the results of these metrics to help predict recovery.
European Pathology Laboratories and COVID-19
Clinical Practice During the COVID-19 CrisisThe infectivity of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), notably when handling human samples, remains poorly understood, as well as the impact of the COVID-19 pandemic in routine clinical and molecular pathology practice, and for personal working in pathology laboratories. This study evaluates the consequences of the COVID-19 crisis in clinical and molecular pathology laboratories in Europe mostly those orientated for diagnosis of thoracic diseases.
