Obesity and Mortality of Critically Ill Patients With COVID-19

COVIDSevere Acute Respiratory Syndrome2 more

Disproportionate impact of COVID-19 in patients with obesity is now well established. Obesity is associated with severe forms of COVID-19 and may be a risk factor of intensive care unit (ICU) admission. Obesity is associated with COVID-19 related hospital death in a large United Kingdom cohort study. However, there is a gap of knowledge on assessment of outcomes such as severity of Acute Respiratory Distress syndrome (ARDS), duration of hospitalisation and mortality in ICU. Moreover, an obesity survival paradox has been observed in patients with ARDS. This raises the question whether the obesity paradox has been broken by COVID-19. The investigators aim to explore risk factors of in-ICU death for patient with COVID-19, including obesity and other chronic diseases and to describe the clinical course and outcomes, including the management of acute respiratory failure and other intensive care management.

Identify the Viral Epitopes of Memory CD8 T Cells From Individuals That Have Recovered From SARS-CoV-2 InfectionDetermine Which SARS-CoV-2 Proteins Are Frequently Recognized by T Cells in Patients With Varying HLA Types

The COVID-19 pandemic is a global emergency threatening to take millions of lives in the United States and around the world. There is no current vaccine strategy against COVID-19 infection caused by a novel coronavirus named SARS-CoV-2. Studies with a related coronavirus called SARS-CoV-1 that caused the SARS outbreak in 2003 indicated that memory CD8+ T cells recognizing viral epitopes persisted for more than 6 years post infection while neutralizing antibodies and memory B cells were short-lived and were undetectable after a short period of time (Tang et al., 2011; Peng et al., 2006; Channappanavar et al., 2014). Thus, including viral epitopes that are recognized by memory CD8+ T cells is imperative for vaccines that can provide long-term immunity against SARS-CoV-2. In this study, blood samples from COVID-19 patients who have recovered from the infection will be used to identify the viral epitopes recognized by their memory CD8+ T cells. This will be accomplished using a genome-wide, high-throughput screening technology developed at Harvard Medical School (Kula et al., 2019) and licensed by the study sponsor, TScan Therapeutics. A 24,000-member library that tiles across all ~100 viral isolates of SARS-CoV-2 that have been sequenced so far has already been synthesized at TScan. Blood samples from convalescent patients are urgently needed to identify T cell receptors and immunogenic viral epitopes on SARS-CoV-2. It is the hope that these data will inform development of a vaccine with the potential for long-lasting protection against SARS-CoV-2.

Characterizing SARS-CoV-2-specific Immunity in Individuals Who Have Recovered From COVID-19

SARS-CoV-2COVID-19

The purpose of this study is to learn more about infection with and recovery from the virus called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Some people know this virus by the name "coronavirus." It can cause the disease called COVID-19. The information gained from the study will be used to help develop better tests for SARS-CoV-2 infection and COVID-19 disease and may help in developing future vaccines and treatments by allowing researchers to determine the difference between the body's immune response to natural SARS-CoV-2 infection and immunization with a SARS-CoV-2 vaccine.

Prediction of Acute Kidney Injury in Patients With COVID-19

Acute Kidney InjuryCOVID-191 more

The two biomarkers determined in urine, "Tissue Inhibitor of Metalloproteinases 2 (TIMP-2)" and "Insulin-like Growth Factor-Binding Protein 7 (IGFBP7)", can indicate the occurrence of Acute kidney injury (AKI) in cardiac surgery and critically ill patients at an early stage. However, no data are available whether these parameters can also predict the occurrence of AKI in the context of COVID-19 infection. An early prediction of AKI can be helpful for the optimisation of therapeutic management to improve patient outcome and for the triage of patients. The aim of this observational study is to evaluate whether the biomarker [TIMP- 2]*[IGFBP7] can predict the occurrence of AKI in critically ill patients suffering from SARS-CoV2 associated acute respiratory distress syndrome.

Surgical Telemedicine in the COVID-19 Pandemic Era

COVIDSurgery

The current COVID-19 pandemic has caused delays in initial or follow-up encounters between surgical patients and physicians. While this delay allows for resource allocation to those most severely affected by the pandemic, surgeons are faced with potential important delays in diagnosis and the expanding backlog of elective cases and initial evaluations. This project will assess surgeon and patient telemedicine perspectives. Pre-pandemic views on telemedicine among a cohort of surgeons will be obtained and compared to views at 3 months from the peak of the pandemic. Patients will be surveyed following telemedicine appointments with an anonymous questionnaire to learn about patient receptiveness to telemedicine. Barriers to implementation will be addressed throughout the duration of the study.

EuRopean Study of MAjor Infectious Disease Syndromes Related to COVID-19

COVID-19SARS-CoV 2

Background Rapid European COVID-19 Emergency Research response (RECoVER), is a project involving 10 international partners that has been selected for funding by the European Union under the Horizon 2020 research framework responding to call topic SC1-PHE-CORONAVIRUS-2020: Advancing knowledge for the clinical and public health response to the SARS-CoV-2 epidemic. MERMAIDS 2.0 is the hospital care study within RECOVER. Rationale Detailed patient-oriented studies are needed to determine the spectrum of SARS-CoV-2 disease and the combined influences of age, comorbidities and pathogen co-infections on the development of severe disease, together with virological and immunological profiles. This research is key to understanding the pathophysiology and epidemiology of this new disease, as well as to identifying potential targets for therapeutic or preventive interventions. Objective To establish the prevalence, disease spectrum and severity, clinical features, risk factors, spread and outcomes of novel 2019 coronavirus infection (SARS-CoV-2) in Hospital Care. Study design Prospective observational cohort study in selected European countries. Study population Children and adults with 1) acute respiratory illness (ARI) presenting to hospital care during the SARS-CoV-2 epidemic (including both COVID-19 and non-COVID-19 patients) and 2) patients with confirmed COVID-19 infection, but with atypical presentation (non-ARI) or with nosocomial acquisition. Sites can optionally participate in the following tiers: Tier 1 (Clinical data and biological sampling) - Clinical samples and data will be collected on enrolment day and then at scheduled time points. Tier 2 (Clinical data an extended biological sampling). - incl. PBMC collection Optional add-on study In a subset of sites and patients, COVID-19 positive patients will be followed post-discharge for 6 months to study clinical recovery and long-term sequelae Main study parameters/endpoints: Prevalence of COVID-19 among patients with acute respiratory illness. COVID-19 disease spectrum and host and pathogen risk factors for severity. Long-term sequelae of COVID-19 requiring hospital care. Proportion hospital-acquired COVID-19 infections and characteristics of nosocomial transmission. Study Duration Scheduled 2 years and based on COVID-19 dynamics. Nature and extent of the burden associated with participation, benefit and group relatedness This study is observational in nature. There will be no direct benefit to research participants. The study may include biological sampling in addition to sampling required for medical management. The results of the tests done on these samples may not contribute to improving the participant's health. Minimal inconvenience and discomfort to the participant may arise from study visits and biological sampling.

Stress Biomarkers Leading to Professional Burnout Among People Involved in a Mobile Intensive Care...

Occupational Stress

This study is aiming at investigating whether professional burnout in people involved in the mobile intensive care unit (in French: Element Mobile de Réanimation, EMR) in Mulhouse (France) can be predicted upstream by a low mindfulness level (as a protective factor) or by a dysregulation of stress pathways with a high level of perceived stress towards an emotional event (psychological index of allostatic load), i.e. an early and silent dysfunctional physiological response (measured by the electrophysiological and biological measurements of allostasis load and parasympathetic brake). It is part of a global approach aiming at identifying levers to prevent the allostatic load of occupational stress related to large-scale health crises.

COVID-19 OUTBREAK AND SOLID ORGAN TRANSPLANTATION (SOT) : AN INTERNATIONAL WEB-BASED SURVEY

COVID-19 OUTBREAK AND SOLID ORGAN TRANSPLANTATION

Background COVID-19 has brought into questioning the equitable distribution of resources. Solid Organ Transplants (SOT) are life-saving procedures. Rapid changes in the management of patients are occurring, with potential for inequity. Drawing on professionals across transplant specialities, we investigated resource distribution specifically for SOT to guide healthcare policies. A multidisciplinary team developed a survey. The survey included demographic questions to contextualise respondents, questions on resource allocation for SOT. Multiple strategies were used to distribute the survey internationally. Descriptive, uni-multivariate ordinal regressions analysis were performed. Open comments were analysed using qualitative methods.
