Filter by:There is evidence that CV-19 is associated with joint symptoms, but there are no specific data on the temporomandibular joint (TMJ). It is also known that the systemic health status can impact the immune system. Given all this, this study aimed to investigate the effect of CV-19 and systemic health status, as determined by the American Society of Anesthesiologists (ASA) Physical Status Classification System 12, on TMJ in patients with TMJ complaints using the DC/TMD scale.
The inactivated Booster Phase 3 study aims to determine the efficacy, safety, and immunogenicity of inactivated COVID-19 vaccines in subjects with a minimum of 90 days and a maximum of 270 days after the second dose of CoronaVac vaccine.
The occurrence of renal failure during severe forms of COVID-19 is common (20-35% of patients treated in intensive care) and associated with an unfavorable short-term prognosis, but the medium-term renal outcome is not is not known. The aim of the study is to establish the frequency of chronic kidney failure after AKI KDIGO 2 and 3 occurring during severe COVID-19 in intensive care.
The newly emerged corona virus disease 2019 (COVID-19) has spread to all over the world, with recent estimates of more than 236 million cases diagnosed and led to 4.8 million deaths as November 20211 .Therapeutic approaches are needed to improve outcomes in patients with COVID-19 since no antiviral agent has yet been proved to be conclusively beneficial in COVID-19 infection,especially in patients with mild to moderate degree of severity There has been growing interest in the anti-parasitic drug,ivermectin, which previously was studied as an antiviral, anti-inflammatory and anti-cancer actions2 .It was also reported to have an in-vitro activity against SARS-CoV-23 .Its antiviral properties was due to the action on importin 2/1 mediated nuclear transport. Ivermectin prevents the binding of viral proteins to importin 2/1 rendering the viral proteins unable to enter the nucleus and cause infection4. Several clinical studies have found a beneficial effect of ivermectin in COVID-195-9 However, some study did not find significant difference between the patient group receiving ivermectin and control group10 .Until now, the controlled trials evaluating ivermectin in COVID-19 are lacking. Ivermectin is safe, with reported side effect of less than 1%. Hence it is essential to conduct a clinical trial with ivermectin in patients with COVID-19 .The objective of this study is to establish the efficacy of ivermectin for COVID-19 patients with mild to moderate disease, compare to usual case alone.
Ventilator Associated Pneumonia (VAPs) are a very common side effect in intensive care units. They are the leading causes of nosocomial infections and excess mortality in intensive care units: associated with a controversial death rate of around 13%. VAPs complicate about 40-50% of COVID-19 acute respiratory distress syndrome (ARDS) and the mortality would be twice higher. Thus, in this context of the COVID-19 pandemic, this represents a considerable rate of patients. Unfortunately, the risk factors for VAPs are poorly understood and the bacterial ecology varies around the world. Also, facing a high prevalence of multi-resistant bacteria in this population, the choice of probabilistic antibiotic therapy is complex and represents a considerable impact for care. New microbiological rapid diagnostic techniques have appeared in recent years, among them the FilmArray® seems to present interesting diagnostic performances with the ability to detects resistance to antibiotics. This technique has been studied in acute community pneumonia but has not been validated in VAP and even less during the COVID-19 period. Investigators decide to conduct this study to investigate if the early identification of the pathogens and their mechanism of resistance using FilmArray® would improve the relevance of the antibiotic treatment. The aim of this project is to evaluate the contribution of a rapid diagnostic technique to the management of Ventilator Associated Pneumonia during COVID-19 acute respiratory distress syndrome before an interventional study.
Investigation of the reactogenicity and immunogenicity of homologous and heterologous vaccine combinations with regard to the formation of SARS-CoV-2 antispike antibodies in health care workers after basic immunization and boost vaccination
The main objective of the study is to assess the level of vaccination coverage (VC) against COVID-19 among migrants, homeless and travelling community, according to their living conditions and housing. The secondary objectives are : - to compare the estimated level of vaccination coverage in the different sites and strata (emergency shelters/hotels, camps, workers' hostels, on the street) with the estimated level in the general population of the same territory obtained from the French Health Insurance data (SIVAC). - identify the obstacles and leverage of vaccination (i.e. mobile team) according to living conditions and habitat (socio-demographic factors, personal health history, vaccine adherence, local health policies, etc.).
SARS-COV-2 infection is responsible for a potentially severe primarily respiratory infection called COVID19. A large proportion of patients, in particular in severe forms, present with thrombotic manifestations (DVT, EP, stroke, thrombosis of dialysis circuits, etc.). A significant proportion is also a carrier of circulating anticoagulant (ACC or LA), making it possible to suggest a diagnosis of APS. This type of autoantibody results in a spontaneous prolongation of the TCA uncorrected by a control serum therefore is quickly diagnosed using standard hemostasis The objective of this study is to describe the diagnosis of thrombotic complications in COVID19 patients presenting a positive lupus anticoagulant type test (LA) or aPL and the associated clinical and biological elements that may have favored thrombosis.
Alsace was particularly and early on affected by SARS-CoV-2 and quickly implemented a reduction in scheduled admissions and non-urgent surgical interventions, making it possible to reduce requests for labile blood products linked to non-urgent surgical procedures. as has been reported in the literature; the population containment measures also led to a major reduction in traffic - and consequently accidents on the public roads. At the same time, other demands for blood products related to activities such as onco-hematology were little affected. Finally, the blood banks have adapted their collection procedure. To answer these questions, we propose to conduct a retrospective study over two parallel periods of 2019 and 2020 of the consumption of blood products on the one hand and the availability of stocks on the other hand.
As the investigators need data on long term outcome of Covid-19, especially respiratory sequelae, a national cohort is required. To better evaluate the potential respiratory sequelae after SARS-CoV-2 infection, it is fundamental to include patients with different management at the acute phase of the Covid-19: ambulatory management, hospitalization in non ICU and in ICU units. That is why the investigators will conduct a national cohort study with all components of french pneumology which will give the investigators the opportunity to include patients in general hospital, in university hospital and in private structure. As it is a "real life" study, the investigators will include all patients who will have a consultation with a pneumologist for an evaluation 5 to 7 months after a Covid-19 infection whatever their acute disease management. The investigators will collect all available data on Covid-19 acute phase, on patients characteristics and comorbidities, on persistent symptoms after Covid-19, on exams results during the outcome evaluation (CT-scan, 6 min walk test, spirometry and DLCO, blood gas, VO2 max if realized).
