Filter by:There is no predictive tool for patients admitted to the emergency department with a suspicion of Covid-19 that will worsen secondarily and require a heavy lifting. In a context of saturation of the healthcare system by the pandemic at Covid-19,it is essential to identify specific, accessible prognostic markers via minimally invasive sampling with low risk of infection for personnel caregiver, for optimal allocation of resuscitation resources. This study proposes to evaluate the biological markers of routine care known to be associated with resuscitation admission in relation to hospitalization on conventional service for the prediction of worsening of patients admitted to the emergencies for Covid-19.
Arriving in December 2019, Coronavirus COVID-19 infection is causing a global pandemic with high morbidity and mortality among adults and especially seniors. The child appears little or no affected by this infection. It is estimated that the child could be asymptomatic or pauci-symptomatic carrier and thus be vector of the disease. For this reason, measures have been taken to close schools and contain populations in a large number of countries, including France. However, there are no data on the prevalence of COVID-19 in children.
Background: Aim: To demonstrate the efficacy of low-dose hydroxychloroquine as primary prevention in healthcare workers Design, participants and interventions: Prospective, randomized, parallel group, double-blinded, placebo controlled, study. including 440 participants who will be randomised to 2 treatment arms: hydroxychloroquine or placebo. Outcome variables: symptomatic or asymptomatic SARS-CoV-2 infection confirmed by PCR, viral load during SARS-CoV-2 infection, seroconversion during the study period, incidence of any acute respiratory infection, days of sick leave. Statistical considerations: No trials have been published investigating the efficacy of HCQ as primary prophylaxis of SARS-CoV-2 infection in health care workers. Thus, sample size calculations in the proposed trial are based on the investigators' best estimates for several parameters. In accordance to the effect of oseltamivir against symptomatic influenza, we assumed an approximate effectiveness of approximately 60% (HR of 0.4) (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6464969/) as realistic. As a prophylactic intervention with HCQ, which may have side effects and for which supply shortage can be expected, was judged justifiable only if its effectiveness is high, we based our sample size consideration on a HR of 0.3. To estimate the probability of an event in both the experimental and the control group, very little data is available. In a Dutch point-prevalence study 0-10% of health-care workers were infected depending on the healthcare institution, depending on the hospital. This point-prevalence study was performed between 6 and 9 March, when the reported number of cases in the Netherlands was 33 and 77, respectively, according to the RIVM (https://www.rivm.nl/nieuws/resultaat-steekproef-4-ziekenhuismedewerkers-heeft-coronavirus). Additionally, in an a report published in the Lancet, 20% of responding healthcare workers in Italy were found to be infected with SARS-CoV2 within less than one month (https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(20)30627-9/fulltext). Several media reports indicate that this proportion is similar across various healthcare institutions and countries (https://www.nytimes.com/2020/03/24/world/europe/coronavirus-europe-covid-19.html) and (https://www.aljazeera.com/news/2020/03/spain-tightens-restrictions-week-lockdown-begins-2003 30191539568.html). As the proposed study will be performed in a high-risk setting, we assumed an event (i.e. PCR positivity) probability of 10% in the control group and 3% in the experimental arm after the maximum study period. In summary, a sample size of 210 participants per arm is necessary to detect a HR of 0.3 with a power of 80.3% with an alpha-error of 0.05. To account for drop-outs and asymptomatic, undetected infection at inclusion or past infection with existing immunity, an additional 10 participants will randomized per treatment arm. The overall study population is therefore 440 participants. Statistical analysis will be based on two populations: A Modified Intention to Treat population excluding those who withdrew consent after randomization and those with a positive serology at baseline. And a per protocol population including all randomized subjects who completed at least 3 out of 4 follow-up visits and took at least 80% of all doses of study medication.
The coronavirus disease 2019 (COVID-19) outbreak is now considered as a public health emergency of international concern by the World Health Organization. In the context of the health emergency, research on the pathogen (the SARS-CoV-2 coronavirus), the disease and the therapeutic care is being organized. Research projects require the use of biological samples. This study aims at setting up a collection of biological samples intended for application projects in any discipline. The main objective of the study is to collect, process and store biological samples from patients and caregivers infected with SARS-CoV-2 (COVID-19) at the biological ressources center of the Bordeaux University Hospital.
Coronavirus 2019 (COVID-19) is a respiratory tropism virus transmitted through droplets emitted into the environment of infected persons. The symptoms can be extremely varied and the course can range from spontaneous healing without sequelae to death. Currently, the diagnosis of certainty for resuscitation patients (by definition "severe") is based on searching for a fragment of virus genetic material within the epithelial cells of the respiratory tree, up and/or down, by PCR. It is to be expected that the epidemic peak will make it difficult (if not impossible) to respect the stereotypical path that is currently in place, due to the lack of space in the specific unit. This will require optimization of care pathways and use of the specific sectors. It is therefore necessary to define the simple criteria, available from the moment patients are admitted, to predict the result of the COVID-19 PCR.
This study explores whether patients acutely hospitalized may have shorter hospitalization and fewer admittances at Intensive Care Units by treatment with azithromycin and hydroxychloroquine.
The Novel Coronavirus (2019-nCoV), also known as Wuhan coronavirus, causes the 2019-nCoV acute respiratory disease.
The Novel Coronavirus (2019-nCoV), also known as Wuhan coronavirus, causes the 2019-nCoV acute respiratory disease. The number of patients infected by 2019-nCoV in Italy closely followed an exponential trend, and Italy reported the highest number of infected patients and deaths in the world excluding China.
Infection with the SARS-CoV-2 coronavirus strain is associated with severe morbidity and mortality estimated today from 2% to 4%. Elderly patients or patients with serious chronic conditions justifying hospitalization are particularly at risk. The risk of infection with SARS-CoV-2 during hospitalization is also substantial and increased in fragile patients. Several cases of infection among Healthcare Professionals had been reported. The hypothesis is that similar to the corona virus agent responsible for SRAS and the influenza virus, nosocomial outbreaks of SARS-CoV-2 to be feared. Health care professionals and caregivers are populations-at-risk as they are exposed in the community and can transmit SARS-CoV-2 to hospitalized patients, and are also exposed to hospitalized patients infected with SARS-CoV-2. Describing hospital-acquired cases and SARS-CoV-2 infection transmission chains in healthcare settings is vitally essential to achieve control of this epidemic. To improve the quality of care and patient safety, this data must be accompanied by an analysis of the impact of infection control measures. In addition, an effective infection control program is urgently required to control the spread of the virus and protect both uninfected patients who require care for other medical or surgical conditions as well as health care professionals. The main objective of this prospective, non-interventional - observational, hospital based study in adults and children is to describe and document suspected or confirmed cases of nosocomial SARS-CoV-2 infection, the clinical spectrum and the determinants (risk factors/protective factors) at participating hospitals. Characterization of the clinical features of the SARS-CoV-2 infection will help to identify potential sources of virus transmission as rapidly as possible and enable implementation of appropriate hygiene practices in hospitals.
This study series consists of four related studies and aims to explore and describe many important elements of alopecia areata over three key areas: (1) the current epidemiology of alopecia areata, (2) the prevalence and incidence of psychiatric co-morbidities in people with alopecia areata, (3) the prevalence and incidence of autoimmune and atopic conditions in people with alopecia areata, and (4) the incidence of common infections in people with alopecia areata.
