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 research hypothesis is that access to prevention and harm and risk reduction associated with the use of psychoactive substances in a sexual context is insufficient for MSM practicing chemsex. This would lead to a lack of awareness of the risks taken and insufficient or inadequate strategies to protect themselves. This qualitative study has a comprehensive objective. The aim is to identify the risks perceived by MSM practicing Chemsex and their coping strategies. The study is based on individual semi-directed interviews and focus group. The criteria for inclusion are: an age greater than or equal to 18 years, being a man having sex with men and having used psychoactive substances in a sexual context at least once in the past 12 months. Participants were recruited through a gay geo-social networking app on mobile phones on a voluntary basis. At the same tim+e, flyers presenting the study are also distributed to the "chemsex" consultations at the Montpellier University Hospital in France as well as to an association fighting against AIDS in Montpellier. Data are subjected to an inductive method analysis, bringing out by constant comparison conceptualizing categories illustrating the experience and making it possible to identify and understand the risks felt and the coping strategies.
This study aims at the assessment of eye movement during autobiographical retrieval (i.e., retrieval of personal memories) in patients with Alzheimer's Disease.
The main objective is to detect with TESLA multiparametric 3 MRI, the MRI secondary changes to protontherapy irradiation and to correlate them with TEL mapping, physical dose and biological dose. A model should thus be able to be proposed at the end of the study.
The purpose of this case-control study is to assess the association of the current and former consumption of tobacco and nicotine in the risk of acquisition of severe acute respiratory syndrome 2 (SARS-CoV-2). the investigators will send a structured interview by mail regarding use of tobacco and nicotine to 2500 healthcare workers (1250 cases with a positive Real Time Polymorphism Chain Reaction (RT-PCR) and 1250 controls with a negative PCR) who were tested in Paris for in March and April, 2020. OR will be estimated by conditional logistic regression modelling with matching for sex and age.
The aim of this study is to assess the nasal and conjunctival response in subjects allergic to birch pollen during controlled exposures in the ALYATEC environmental exposure chamber (EEC)
This study compares the diagnostic performance of a nasopharyngeal swab antigenic test versus the RT-PCR Covid-19 reference test performed with the AllplexTM 2019-nCoV kit (Seegene, South Korea) in symptomatic children presenting at the hospital.
Objective measurement of physical activity has several advantages compared to declarative measures: exemption from memory bias and desirability bias, more precise evaluation, taken into account activities of low intensity, measurement of physical activity and sedentariness profiles (number and duration of periods of activity, number of breaks in sedentary lifestyles). The aim of this study is to assess the early postoperative mobility of patients who have undergone pulmonary excision by thoracoscopy or robot surgery using ActiGraph GT3X accelerometer. This assessment will serve as a reference element for further studies.
The management of patients with primary immune deficiency is increasingly codified, however contraception and pregnancy have not yet extensively studied or codified, and the medical monitoring and the prevention of infectious complications thus remains at the discretion of the practitioner. The aim the research is to study the obstetric features and outcome of patients with primary immune defects.
This study aims at evaluating the prevalence of Clonal Hematopoiesis of Indeterminate Potential (CHIP) in patients over 75 presenting with a first cardio-vascular event (CVE). The investigators will also determine if CHIPs are more frequent in this population compared to a control cohort without CVE. An association between CHIP, a systemic inflammation and increased atherosclerosis will also be assessed.
The NEwTON AF study is a multi-center, global, prospective, single arm study to establish the safety and effectiveness of the IntellaNav StablePoint Catheter and Force-Sensing System in subjects with symptomatic, drug refractory, recurrent paroxysmal atrial fibrillation.
