Filter by:This study is a non-randomized, quasi-experimental, monocentric study comparing two prenatal monitoring modes in low-risk pregnancy: including at least one remote consultation (phone or teleconsultation) versus face-to-face adapted to confinement. The quality of care perceived by the pregnant women were evaluated according to monitoring modes set up during the COVID-19 pandemic confinement period. The women included planned to give birth at the regional academic Maternity of Nancy, France.
This is a Phase 1/2/3, randomized, placebo-controlled, observer-blind, dose-finding, vaccine candidate-selection, and efficacy study in healthy individuals. The study consists of 2 parts: Phase 1: to identify preferred vaccine candidate(s) and dose level(s); Phase 2/3: an expanded cohort and efficacy part. The study will evaluate the safety, tolerability, and immunogenicity of 3 different SARS-CoV-2 RNA vaccine candidates against COVID-19 and the efficacy of 1 candidate: - As a 2-dose (separated by 21 days) schedule; - At various different dose levels in Phase 1; - As a booster; - In 3 age groups (Phase 1: 18 to 55 years of age, 65 to 85 years of age; Phase 2/3: ≥12 years of age [stratified as 12-15, 16-55 or >55 years of age]). The candidate selected for efficacy evaluation in Phase 2/3 is BNT162b2 at a dose of 30 µg. Participants who originally received placebo will be offered the opportunity to receive BNT162b2 at defined points as part of the study. In order to describe the boostability of BNT162, and potential heterologous protection against emerging SARS-CoV-2 VOCs, an additional dose of BNT162b2 at 30 µg will be given to Phase 1 participants approximately 6 to 12 months after their second dose of BNT162b1 or BNT162b2. This will provide an early assessment of the safety of a third dose of BNT162, as well as its immunogenicity. The assessment of boostability will be further expanded in a subset of Phase 3 participants at selected sites in the US who will receive a third dose of BNT162b2 at 30 µg or a third and potentially a fourth dose of prototype BNT162b2VOC at 30 µg (BNT162b2s01, based upon the South African variant and hereafter referred to as BNT162b2SA). A further subset of Phase 3 participants will receive a third, lower, dose of BNT162b2 at 5 or 10 µg. To further describe potential homologous and heterologous protection against emerging SARS-CoV-2 VOCs, a new cohort of participants will be enrolled who are COVID-19 vaccine-naïve (ie, BNT162b2-naïve) and have not experienced COVID-19. They will receive BNT162b2SA given as a 2-dose series, separated by 21 days. To reflect current and anticipated recommendations for COVID 19 vaccine boosters, participants in C4591001 who meet specified recommendations and have not already received one, will be offered a third dose of BNT162b2 after their second dose of BNT162.
Covid-19 (English acronym meaning coronavirus disease 2019) is an emerging infectious disease caused by a strain of coronavirus called SARS-CoV-2. The current pandemic has resulted in a significant number of admissions in the emergency room (ER) due to suspicion of COVID-19 infection. Use of lung ultrasound is standard practice to diagnose acute respiratory failure in ER. Recently, typical lung ultrasonographic characteristics of COVID-19 disease has been described. During the COVID-19 pandemic, the use of this tool could be of interest in order to allow an early, simple and reliable triage in patients with suspected COVID-19 infection admitted in ER. In addition, the visualization of early signs in specific areas could be a predictive marker of the severity of the disease. The objective of this project will be to study the association between the signs on lung ultrasound and the result of RT-PCR in patients with suspected COVID-19 infection in the ER.
The SARS-CoV-2 pandemic has resulted in an international shortage of the nasopharyngeal (NP) swabs used to collect sample for virological testing. This shortage has become a crisis as testing capacity is growing, and threatens to become the bottleneck at University of Virginia Health System and in the Commonwealth of Virginia, as it already is in other testing centers. To resolve this crisis, a team in the Clinical Microbiology Laboratories at University of Virginia Medical Center has been working closely with biomedical engineers in the University of Virginia (UVA), School of Engineering and with high volume domestic manufacturers developing injection molded polypropylene flocked nylon NP swab. This prototype will be tested for non-inferiority relative to existing, already validated NP swabs ("control swab") for purposes of molecular microbiology: i.e. the polymerase chain reaction (PCR) tests used for virological testing for SARS-CoV-2. Specifically, the nasopharynx of patients with Covid-19 and patients under investigation (PUI) for Covid-19, the disease caused by SARS-CoV-2, will be swabbed using a prototype swab and a control swab (the standard of care swab), and test for concordance of SARS-CoV-2. In all cases the swab will be transported in validated FDA cleared viral transport medium (VTM) as per standard operating procedure at University of Virginia Medical Center.
Characterization of fungal infections in COVID-19 infected and mechanically ventilated patients in ICU
The purpose of this study is to asses the efficacy of the Gammacore device reducing the need for mechanical ventilation in patients diagnosed of Covid-19
This concerns a single-center prospective interventional cohort study. Laboratory-confirmed COVID-19 patients will be asked to donate blood at at least two different timepoints. This will allow us to investigate T and B cell evolutions during the course of infection and recovery. The expected duration of the study is four months or the total duration of the SARS-CoV-2 circulation in Belgium (whichever is shortest).
COVID-19 Active Research Experience (CARE) is an observational, direct-to-participant, web-based, longitudinal study of adults with COVID-19 or COVID-19 like illness or who were vaccinated against COVID-19 to better understand risk factors, symptoms, and treatments for COVID-19 illness and vaccine safety and effectiveness.
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.
EVIDENCE is a non interventional, French, multicenter study. Patients will be screened by local severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) immunoassay in their oncology department (rapid diagnostic test (RDT) or enzyme-linked immunosorbent assay (ELISA)). In patients with positive local SARS-CoV-2 immunoassay, a centralized SARS-CoV-2 ELISA will be performed in order to double check the immune response of all patients considered immune by local immunoassay.
