Immune Response of Asymptomatic EHPAD Employees Infected With COVID-19

COVID-19

The investigators performed in April 2020, a screening campaign of asymptomatic staff working in elderly nursing homes in Paris France (EHPAD), where the virus had been circulating actively in March and April 2020. Among 241 employees tested in four nursing homes, 32 (13.2%) were asymptomatic carriers of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-Cov-2). Few data are available concerning the humoral immune response of asymptomatic carriers, the elicitation and duration of neutralizing antibodies and the duration of protection. The purpose of the study is to determine whether these asymptomatic persons develop a humoral immune response, whether this immune response is durable and whether it is protective against the risk of reinfection

Remote Monitoring of COVID-19 Positive Outpatients

Covid19

This study seeks to evaluate how secondary data retrieved from remote physiological monitoring performed during routine outpatient/at-home care periods can allow for the discovery of novel physiomarkers that predict acute deterioration or hospitalization among people testing positive for Coronavirus Disease 2019 (COVID-19).

CAPTION AI to Minimize Risk of COVID Exposure

COVID-19

Participants scheduled for for an echocardiogram (echo) and being evaluated for, or is positive for COVID-19 will be asked if they would be willing to have their echo done using a new software program on one of the hand-held ultrasound scanners. The new software program guides the investigator, or any other non-sonographer, to take the best possible pictures of the participants heart. The prior version of this software is already being used clinically and is FDA approved. The main reason for using the updated version is that it's faster and better in terms of guiding the user.

Serology to COVID-19 for Recording Exposures and Evaluating Needs

Covid19Coronavirus1 more

As the global and pandemic spread of the novel coronavirus (SARS-CoV-2, COVID-19) continues, many knowledge gaps remain with regard to the epidemiology and transmission of infection, as well as the normal immunological responses after viral exposure. Cincinnati had its first confirmed case of COVID-19 on March 14, 2020, and despite extensive shelter-in-place and social distancing efforts, community spread continues at over 150-200 new cases per week. As new residents and fellows arrive in July 2020 to Cincinnati Children's Hospital Medical Center (CCHMC), many of whom come from metropolitan areas across the country, it is imperative that investigators determine the current prevalence of infection, measure the cumulative incidence of infection over the next 12-24 months, investigate the normal antibody patterns after infection, and help elucidate what constitutes a protective immunological response. The investigators have a unique but time-limited opportunity to optimally track the epidemiology and natural history of SARS-CoV-2 infection among trainees at CCHMC, including risk factors for transmission and immunological recovery. SCREEN will investigate epidemiological and immunological features of SARS-CoV-2 virus infection within the cohort of CCHMC residents and fellows who have patient contact. By collecting and analyzing weekly serial samples for SARS-CoV-2 (nasal swab for virus by PCR) and monthly serological exposure (serum antibodies by ELISA), the investigators will determine the prevalence and cumulative incidence of infection by SARS-CoV-2; the investigators will also document the antibody responses over time and identify cases of apparent viral recrudescence or re-infection.

Risk Factors for COVID-19 Mortality

COVID-19 Virus InfectionPopulation at Risk1 more

COVID-19 pandemic has deeply burdened hospitals all over the world. A two-stage disease has been hypothesized due to quick worsening of clinical status after 7-10 days from the beginning of first symptoms, generally flu-like symptoms. Predicting clinical worsening could help to address major efforts towards higher risk patients. During the last year most observational studies, generally retrospective, has been conducted, identifying some risk factors such as age, obesity, male gender, cardiovascular disease, COPD, diabetes etc. The study goal is to collect systematically a variegate amount of clinical, biometric, laboratory and radiological data from patients admitted to the Emergency Medicine Ward of Piacenza Hospital (Italy), in order to prospectively analyze what characteristics are associated to higher risk of mortality.

Biomarkers for Dexamethasone Response in Sars-Cov-2 / COVID-19 Pneumonia

PneumoniaViral1 more

The primary objective of this study is to demonstrate (at the time of admission) biomarkers of interest (Human Plasma BAK125 panel + interferon panel) for dexamethasone responders versus non-responders in SARS-CoV-2 hypoxemic pneumonia. The secondary objectives are to describe and compare between groups: The number of days without mechanical ventilation The need for mechanical ventilation 28-day mortality Progression towards acute respiratory distress syndrome (ARDS) Change in the qSOFA score Length of hospitalization The change in the extent of lesions on thoracic computed tomography scan between inclusion and D7 (or the day of discharge from hospital if <D7) Change in biomarkers on D0, D2, D4, D7 (NFS, liver tests (ASAT, ALAT), Creatinine, Albumin, CRP, D-dimers, Ferritin, LDH, lymphocyte phenotyping) Demonstrate other biomarkers of interest from the usual management (NFS, liver function tests (ASAT, ALAT), Creatinine, Albumin, CRP, D-dimers, Ferritin, LDH, lymphocyte phenotyping) Change in biomarkers evaluated by mass spectrometry (on a blood sample) on D0 and D7 +/- 2 days The initial viral load (within 48 hours preceding D0) and at D7 of inclusion estimated from the nasopharyngeal SARS-CoV-2 RT-PCR Initial SARS-CoV-2 serology and on D7 from inclusion The A38G polymorphism of the gene coding for Club Cell Secretory Protein (CCSP) for each patient Short-term complications related to corticosteroid therapy The quantitative and qualitative impact of corticosteroid therapy on lymphocytes from patients with COVID-19.

COVID-19 Serological Testing of Patients With a Mental Disorder From the Catchment Area of the Capital...

Covid19Severe Mental Disorder

The pandemic of coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has lately caused worldwide health problems. Patients suffering from a severe mental disorder are at increased risk for infectious diseases. The primary aim of the present surveillance study is to perform COVID-19 serological testing on patients with a diagnosis of schizophrenia, schizoaffective disorder or a bipolar affective disorder. Patients from the catchment area of the Capital Region of Denmark will be COVID-19 tested at baseline (0 months) and again at 6 and 12 months, in order to follow the spread of COVID-19 among this vulnerable patient population.

A Wearable, Battery-free Screening System for SARS-CoV-2, the Virus Causing COVID-19 Infection

Covid19

The corona virus disease (COVID) pandemic has highlighted the importance of rapid, readily available screeners and diagnostics to identify infected individuals. Recent studies have demonstrated that portable electronic nose sensing devices can detect volatile organic compounds (VOCs). These compounds are end products of human metabolism or of enteric bacteria and are excreted through the skin or exhaled breath. Importantly, the sensing devices can be adapted into a wearable device providing continuous monitoring. Our goal is to develop a battery-free, electronic nose sensor to serve as a screener and detect VOC patterns associated to patients with symptomatic and asymptomatic COVID-19 without being invasive. To test the screening ability, devices will be worn by COVID-19 positive and negative patients hospitalized at Nebraska Medicine.
