Filter by:The main objective of this CorDial-S proof-of-concept study is to evaluate the ability to detect COVID-19 infection in nasopharyngeal swabs with CorDial-S and compare it to the PCR technique currently in use. Saliva analysis will be the subject of secondary analysis. The CorDial-S medical device could allow the specimens to be analyzed using a small portable device and the results to be returned in minutes to the medical team and the patient, and communicated in real time with a telemedicine and remote monitoring system to the health authorities to allow the necessary protective, containment and therapeutic management measures to be put in place if necessary. The benefits would be 1. greater sensitivity 2. a great speed because 8tests could be performed at the same time with a result in a few minutes 3. a very high specificity at least equivalent to PCR. This new diagnostic strategy could become extremely valuable in the fight against COVID-19, especially in the case of very long-term persistence and incomplete vaccination of the French and foreign population.
The main objective of this cohort is to characterize COVID-19 patients hospitalized in infectious disease department. The collection of clinical and biological data from start of hospitalization to long-term follow up will contribute to a better description of the patient care, to the identification of predisposition to complication related to the disease, and to the evaluation of the impact of different therapeutical strategies.
The study aims to investigate SARS-CoV-2 susceptibility, transmission and disease severity in healthcare workers and patients. Residual specimens from an existing collection of samples in viral inactivating buffer and derivatives and serum from the Crick COVID-19 Consortium Testing centre (Cohort A1) and additional biological material collected prospectively (Cohorts A2 and B) will be used for research into SARS-CoV-2 transmission, evolution and immune control. This testing centre is a partnership between UCLH and The Francis Crick Institute to provide COVID 19 RT PCR testing for healthcare workers (HCWs) and patients in London Hospitals and care homes. A third group (Cohort C) of the study will allow for collaborative work with other REC approved research studies that have used the Crick COVID-19 Consortium Testing centre and will involve the use of study samples already collected from each study to be analysed under the SARS-CoV-2 Longitudinal Study end points
Analysing ths spread of COVID-19 epidemics in a timely manner is key to implementing public health control strategies. The investigators propose to analyse a large set of laboratory SARS-CoV-2 RT-PCR data to explore potential links between Ct values and epidemic parameters.
As part of the Coronavirus Infectious Disease 2019 (COVID19) pandemic, the hospital care system is facing a major strain. Patients with SARS-Cov2 (severe acute respiratory syndrome coronavirus 2 ) infection can worsen very quickly, possibly presenting, within hours, severe respiratory failure requiring urgent specialized care. Therefore, it is essential to develop emergency assessment tools to assess relevant criteria to decide which patients must be kept under hospital monitoring and which patients can be treated on outpatient care. The aim of this study is to assess the efficacy of STST in the decision to hospitalize patients consulting emergency department for a SARS-Cov2 infection. The investigators wish to show that the addition of this test to the usual hospitalization criteria reduces the proportion of patients hospitalized 48 hours after their first visit to the emergency department.
This study will evaluate the associations between vascular parameters and clinical outcomes in patients hospitalized with COVID-19. The vascular function and structure of individuals with COVID-19 admitted to the General Hospital of the University of Sao Paulo will be assessed in the first 72 hours of hospitalization. Then, participants will be followed up until hospital discharge/death. Logistical regressions will be run to evaluate if vascular function/structure can predict ICU admissions, intubation, thrombosis or death.
There is an unmet need to evaluate the impact of sub-clinical/mild COVID19 disease in the outpatient setting on prevalent and incident renal injury, as this data is currently unavailable. To capture the diversity of race/ethnic risk and COVID19 related municipal shelter-in-place guidance, the investigators will enroll COVID19-negative and COVID19-positive samples balanced by race/ethnicity from 3 different states, California, Michigan, and Illinois. Study endpoints will be assayed from urine samples mailed to the study team at 2, 6, and 12 months after their date of PCR test, with no requirement for these individuals to leave their homes to participate.
COVID-19, the coronavirus responsible for the pandemic that began at the end of 2019 in China, spreads through respiratory droplets and direct contact. The most common symptoms of the disease include fever, cough, asthenia or myalgia, wheezing and headache, and the most serious complication is acute respiratory distress syndrome (ARDS). The new coronavirus has continued to spread to multiple countries and continents so much so that the epidemic was declared a Public Health Emergency of International Interest (PHEIC) by the World Health Organization (WHO) on January 30, 2020. In the first phase of emergency worldwide, characterized by high morbidity and mortality, scientific interest has been mainly directed to the study of the transmission mechanisms of the infection, diagnostic tools and therapies for ARDS, especially in elderly and co-morbid patients. Interest has rapidly spread to other categories of patients and in particular to pregnancy, on which the virus could impact in different ways, with consequences for both the mother and the fetus. A recent systematic review that included all published reports on Coronaviruses (COVID-19, SARS, and MERS) in pregnancy showed that preterm delivery is the most frequently reported adverse event in these women, and that COVID-19 is associated with an increased risk of preeclampsia and caesarean section. Nonetheless, the limited sample size, the main inclusion of cases reported for acute respiratory symptoms, the lack of information on previous pathologies potentially capable of complicating pregnancy, do not allow for the extrapolation of strong evidence on the course of infection in pregnancy. Therefore, the current status of the scientific literature does not allow for general and wide-ranging implications. THe investigators therefore believe it is particularly useful to investigate maternal and fetal outcomes in this new broader scenario, including all pregnancies associated with asymptomatic or symptomatic SARS-CoV-2 infection, found in any gestational period, in order to evaluate in a "real world scenario" "Actual rates of maternal-fetal and neonatal adverse events
The SARS-Cov2 pandemic remains associated with many concerns. One of the them is the real frequency of likely re-infection and subsequently the level of protection conferred by the acquired immunity following primary-infection. We propose to analyze a large set of laboratory data produced since the early beginning of the SARS-Cov2 spread in the French population to identify recurrent infection events and, more generally, gain insight about infection kinetics.
Countries that have not carried out universal mass vaccination against tuberculosis (BCG) have been shown to have higher incidence and death rates due to COVID-19 than countries with mass, long-term BCG immunization programmes. The aim of the study is to answer the following questions: 1. Does BCG vaccination affect the course of COVID-19 (number of cases/deaths/severity of symptoms)? 2. Will the course of COVID-19 be milder among subjects with a negative TB skin test (PPD RT 23 SSI) after an additional dose of BCG than in case of non-vaccinated subjects? 3. Do people with a positive TB skin test have a milder course of COVID-19 infection than people with a negative test result? A multicenter, randomized, partially blinded, placebo-controlled study will be conducted in Rzeszow/Krakow/ Katowice/Warsaw on a group of 1000 volunteers, health care workers according to the following schedule: V 0-1: inclusion/informed consent/interview; V2: administration of TB skin test/anti-SARS-CoV-2 IgG test/serum banking*; V3: TB skin test (TST) interpretation and subjects' division into three groups: (I) positive TST - observation; (II) negative TST- BCG-10 vaccination; (III) negative TST - placebo. Division into groups II and III based on randomisation; V4: serum banking*. Parallel beginning from V3, weekly telephone monitoring participants' health status; In case of COVID-19 symptoms a nasopharyngeal swab to confirm SARS-CoV-2 infection + serum banking*. V5: 3 months after vaccination at the end of the study: history/anti-SARS-CoV-2 IgG test, serum banking*. Statistical analysis - comparison of the course of COVID-19 in groups: (I) with positive TST + observation, (II) with negative TST + BCG, (III) with negative TST + placebo - should demonstrate whether mass BCG vaccination has an impact on the incidence and course of COVID-19. * to measure the level of cytokines involved in cell-mediated immunity process
