Filter by:The COVID-19 global pandemic has led to a major professional and social national reorganization: professional because it involves a redeployment of medical staff and material resources, and social because it imposes prolonged containment measures on an entire population. The maxillofacial trauma activity is mainly linked to sports or leisure accidents, fights and road accidents. It seems to appear since the beginning of containment measures a significant drop in maxillofacial trauma activity at the national level, which, if it is demonstrated in a significant way in several French hospital centers, would allow to redeploy the material and human resources related to this activity on sectors in tension due to the pandemic.
Study of the cellular immune response during the SARS-CoV-2 infection and identify cytokinic profiles in caregivers exposed to the virus with asymptomatic forms of COVID19, patients with an asymptomatic form followed in ambulatory care and patients hospitalized in the infectious disease department or in resuscitation at the CHU de Nice COVID-19 according to their clinical symptomatology and the kinetics of clinical aggravation using functional tests evaluating the Th1 type immune response. The project is divided into a clinical component comprising the study of the immune response in different populations and a cellular component focusing on the in vitro study of different immunomodulating treatments on their ability to induce an anti-viral Th1
Participants will be randomized in a 1:1 ratio to receive Colchicine plus current care per UCLA treating physicians versus current care per UCLA treating physicians alone (control arm). Importantly, this adaptive trial design allows for patients in either study arm to receive other investigational drugs for COVID-19 as new science emerges.
Off label study to evaluate the efficacy of HCQ for pre-exposure prophylaxis (PrEP) to prevent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. 350 participants will be assigned to the group that takes HCQ or the group that opts to not take the study medication. Participants will be NYULH HCW at high risk for occupational exposure to SARS-CoV-2. Study timepoints will include screening/enrollment, 30 day, 60 day, and 90 day visits. Questionnaires, and DBS will be collected in all timepoints.
Loss of sense of smell and taste has been anecdotally reported during the covid-19 epidemic. The study investigators wanted to describe the prevalence of olfactory and gustatory dysfunction and assess the factors associated with positive SARS-CoV-2 infection.
This is a Phase II study. This research study is being conducted to use convalescent donor plasma in seriously ill patients who have COVID-19.
Context: On March 11, the World Health Organization (WHO) announced the current corona virus disease 2019 (COVID-19) outbreak as a pandemic. The first laboratory-confirmed case of COVID-19 in Austria was announced on February 27, 2020. Since then, the incidence of infection follows a gradual increase. Measurements taken by the Austrian government include travel restrictions, closing of national borders, social distancing, a mandatory use of facemasks in public, and closing of stores and restaurants. The underlying aim of those imposed restrictions is to contain the viral transmission and to slow spreading of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Objectives: The aims of this study are to determine i) how many employees in Austrian trauma hospitals and rehabilitation facilities have virus specific IgG and IgM antibodies against SARS-CoV-2, ii) how many are active virus carriers (symptomatic and asymptomatic), iii) how many employees are in their incubation period during the study period, and iv) to calculate the SARS-CoV-2 prevalence together with a specific occupation associated infection risk within the different specifications of health care workers. Study Design: Open uncontrolled observational cross-sectional study. Setting/Participants: A total of 4000 employees in 11 Austrian trauma hospitals and rehabilitation facilities of the Austrian Social Insurance for Occupational Risks (AUVA) will be invited to participate in the study. Study Interventions and Measures: An antibody test for SARS-CoV-2 specific IgG and IgM antibodies, and a RT-PCR test based on oropharyngeal swab samples, as well as laboratory-based antibody tests using ELISA, will be implemented to ensure protection and preservation of health in hospital staff and are not part of the study. The tests will be conducted twice, with approximately two weeks in between testing. The results of the tests will be used for statistical analysis in this study together with a questionnaire including questions related to personal health, traveling activities, living situation, as well as inquiries of symptoms and comorbidities.
Rationale : The emergence of the novel, pathogenic SARS-coronavirus 2 (SARS-CoV-2) threatens public health. To date, there are no effective drug option to prevent the infection, nor therapeutics for controlling the deadly COVID-19. However, the majority of patients infected with SARS-Cov-2 eliminate the virus by mounting a protective antiviral immune response, associated in particular with the production of neutralizing antibodies. Neutralizing antibodies could be of particular interest for therapeutic purposes, but also for preventive applications, to protect people who have never been in contact with the virus, or immunocompromised patients. The objectives of this study are : - To generate human monoclonal antibodies neutralizing SARS-Cov-2 from immortalized B cells of convalescent patients. - To compare the serological profiles between convalescent patients that develop mild or uncomplicated illness and convalescent patients that develop a more severe disease, that required hospitalization and oxygen support. - To compare for each patient the neutralizing efficiency of plasma to the neutralizing capacities of the monoclonal antibodies generated with immortalized B cells.
University of Warwick (Coventry, UK) and NTUU "Igor Sikorsky" Kyiv Polytechnic Institute (Kyiv, Ukraine), together with ClickMedix LLC, have developed an app and a chatbot "AiM COVID" for efficient monitoring and mitigation of COVID-19. These products are available for free download on computers and mobile phones. These can be used by a wide range of users from various sectors - patients and people living with them, doctors, nurses, specialists, community health workers, hospitals, clinics, hospital IT staff, MHFA, and insurance companies.
The Nancy Cov-H-AKI: study is a prospective, non-randomized, monocenter study performed in patients hospitalised for either the severe or the critical form of Covid-19. The main objective of the Nancy Cov-H-AKI study is to evaluate the association of variations (from inclusion to 72H post-inclusion) of 5 blood-based cardio-vascular-renal biomarkers selected a priori, cardiac (NT-proBNP), coagulation (D-dimers), related to the renin angiotensin aldosterone system (ACE2) and renal (Penkid, and NGAL) with the appearance of acute kidney injury KDIGO grade 1 or higher OR cardiac injury in patients hospitalised for either the severe or the critical form of Covid-19
