There are about 36633 clinical studies being (or have been) conducted in France. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The purpose of this study is to define seroprevalence of anti-SARS-CoV2 among children of Hospital Workers in APHP, particularly exposed population, according to parents' SARS-CoV2 serological status.
Hospital mortality attributed to SARS-CoV-2 in France increased daily by 28% in the week before confinement. The week following this decision, the daily increase was 30%. During the week of the second week of confinement, it started a decline of 19% estimated over the last 5 days, reaching the cumulative number of 2606 deaths on 29/3 (site https://www.eficiens.com/coronavirus- personal statistics / and calculation). The diagnosis of viral carriage by RT-PCR is reserved for symptomatic cases among caregivers, due to the shortage of available tests and the cumbersome implementation. The carrier diagnosis is the benchmark, on which are implemented the therapeutic strategies and established the national statistics. It can present false negatives, linked to a research too early or too late in relation to the infection, or to a technical defect of the nasal swab sample. Caregivers on the front line in patient care, in hospitals or in the city, have only partial access to this diagnostic test, depending on the existence of symptoms. The implementation of a systematic serological screening, planned by the government and which cannot be based only on the search for the virus, will make it possible to inform the caregivers presenting symptoms or not, of their serological status, and therefore of their degree immunity or, on the contrary, susceptibility to infectious contacts. It should therefore be very voluntarily requested. On the occasion of this screening, the constitution of the COVID-3S cohort will make it possible to verify the degree of contamination in an asymptomatic population, information which is sorely lacking for the estimation of the immune coverage of the population. The implementation of the Covid-3S study will be based on the work of the National Reference Center of Pr B Lina, from the COVID-SER cohort, for the selection of the most efficient test (s). It seems useful to initiate the constitution of this cohort as soon as possible in relation to the evolution of the epidemic. Pending receipt of official recommendations, the lack of knowledge of the performance of serological tests means that it should be applied first to health professionals, better able to appreciate its limits, for the initial period before determining a validated serological screening strategy. Once the strategy has been specified, the gradual expansion of screening to the patient population will provide a more representative basis for the construction of epidemiological models for evaluating strategies.
COVID-19 is a new emerging disease caused by infection with the SARS-CoV-2 coronavirus, with no specific therapeutic options. Since the end of February 2020, the Strasbourg University Hospital (HUS) had faced a sudden increase of patients with COVID-19 resulted from a SARS-CoV-2 superspreading event (religious meeting). Infected individuals went to regional hospitals, and this led to a cluster of infected healthcare workers at the Strasbourg University Hospitals from the first week of March. To date, several hundred Strasbourg hospital workers have presented a SARS-CoV-2 infection confirmed by the RT-PCR test from a nasopharyngeal sample. Most of them developed a mild form of COVID-19. It is important to understand how far the infection has spread in the hospital staff, and to which extent the individuals who have been infected develop antibodies against SARS-CoV-2.
The intensive care unit occupies a particular place in our health care system. The urgency of the clinical situations, the proportion of deaths encountered, and the daily workload is likely to generate suffering among staff. The health crisis linked to SARS-COV-2 is unprecedented and has leads to the unprecedented mobilisation of care providers, particularly in the ICU. Faced with the massive and growing influx of patients, human, therapeutic and material resources are overwhelmed and the teams are faced with an unusually heavy workload in a context of extreme tension. These professionals are thus exposed to a risk of over-investment, in a context of acute and repetitive stress, over an indeterminate period of time combining workload, emotional intensity with specific ethical issues, simultaneously affecting the professional sphere but also the personal and family sphere (confinement, risk of contamination). Now more than ever, the mental health of caregivers is an important concern, as highlighted by the CCNE. Mental health is understood in the way in which the individual responds specifically to work-related suffering by developing individual and collective defensive strategies. Thus, the issue of mental health in the ICU cannot be considered without taking into account the strategies that professionals put in place to combat stress and to contribute or not to the construction and stabilization of the work collective (collaboration, support). Ethical and/or psychological support systems have been set up in most of the establishments involved in the care of Covid-19 patients. However, the adequacy of these systems relative to the needs of professionals during and after the crisis is not yet known. We hypothesize that the psychological and social repercussions of this pandemic as well as the individual and collective strategies deployed by ICU care providers to deal with it will evolve in view of the progression of the crisis but also of the various types of support, particularly psychological and/or ethical, available to them.
This controlled-randomized trial compares the artificial intelligence Genius® system assisted (Genius+) to standard (Genius-) colonoscopy. The aim of this study was to evaluate the impact of Genius® system on ADR in routine colonoscopy. The secondary aims will be the impact of Genius® system on polyp detection rate (PDR), serrated polyp detection rate (SPDR), advanced neoplasia detection rate (ANDR), mean number of polyps (MNP), polyp type and localization, and operator type (according to basal ADR).
This study aims at defining the role of O-GlcNAcylation is in the physiopathology of systemic lupus erythematosus (SLE). O-GlcNAcylation is a metabolic pathway potentially implicated in SLE with potential for the discovery of new therapeutic strategies.
Hypertrophic cardiomyopathy (HCM) is a frequent cardiac pathology with an estimated prevalence of 1/500 in France. The main risk factor for sudden death in this pathology is the presence and extent of left ventricular obstruction. To date, the only method allowing a reliable assessment of the extent of left ventricular obstruction is Doppler echocardiography. All patients with HCM should undergo cardiac magnetic resonance imaging (MRI) to confirm the diagnosis and for the detection of fibrosis, but conventional sequences cannot reliably assess the obstruction. 4D-flow MRI provides a complete coverage of an entire volume with the ability to simultaneously measure the outputs of all vessels within that volume in a single sequence and might be able to quantify left ventricular obstruction. The main objective of this study is to compare the quantification of left ventricular obstruction in hypertrophic cardiomyopathy by Doppler echocardiography and 4D flow MRI.
Severe infections (sepsis) are a common cause of admission to the intensive care unit. They represent a significant health risk for patients in the short and medium term. They are particularly linked to a change in the function of immune cells. In some patients, a state of pseudo-dormancy of monocyte and macrophage-type immune cells, called immunosuppression of myeloid cells, is observed. This situation leads to a worsening of the infection, so it should be avoided because it represents a danger for the patient even when they ar receiving antibiotics. At present, these events are still very poorly understood. Research is essential to understand how this state of immunosuppression of myeloid cells is established in order to adapt existing treatments or find new ones. Laboratory studies on animal models of septicaemia have shown that this state of immunosuppression of myeloid cells is closely linked to a change in the production of energy by myeloid cells (monocytes and macrophages). The functioning of the mitochondria ("energy factory" of the cells) in these cells is impaired. Thus, restoring mitochondrial function in myeloid cells could be a therapeutic solution against the immunosuppression of myeloid cells during severe septicaemia. The objective of this study is to verify whether alterations in mitochondrial function in myeloid cells also occur in patients with bacterial infection compared to patients without bacterial infection.
The induction of general anaesthesia is associated with a fall in lung volume due in particular to a decrease in muscle tone and the formation of denitrogenation atelectasis. Many recent studies insist on the need to apply a so-called "protective" strategy of intraoperative ventilation, which combines the use of recruitment manoeuvres, reduced tidal volume (Vt) (6-8ml/kg) and positive expiratory pressure (PEEP) to prevent these phenomena. However, the setting of PEEP remains debated and several authors agree on the need to individualize ventilatory parameters, particularly in obese patients, without describing the individualization tools. In the ICU, it has been shown that electrical impedance tomography (EIT) can be used to individualise the PEEP level in a simple and non-invasive way. Therefore, we wish to determine whether the use of this technique during general anaesthesia allows for the individualization of PEEP, and whether the value determined is correlated with the body mass index (BMI).
The purpose of this study is to evaluate the efficacy of a treatment regimen of JNJ-73763989 + pegylated interferon alpha-2a (PegIFN-alpha-2a) + nucleos(t)ide analog (NA).
