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.
This is a prospective study involving 50 patients, with acute SARS-CoV-2 infection and a positive RNA detection. Men will give semen, saliva, urine and blood specimens following RT-PCR diagnosis and 15, 30, 60 and 90 days after. SARS-CoV-2 RNA will be detected in seminal plasma, native semen cells and processed spermatozoa. The purpose of this study is to seek the presence of SARS-CoV-2 in semen, to determine its localization and infectiousness and to assess the efficiency of spermatozoa processing methods to obtain virus free spermatozoa.
The purpose of this study is to assess whether immunosuppressive therapies used by patients with chronic inflammatory rheumatic diseases have an impact on the viral load and the humoral and cellular responses during viral infection with SarSCoV2, compared to members of their family cluster infected with the same viral strain.
Iron is a biologically essential micronutrient. Iron deficiency alters erythropoiesis and is considered as a major cause of disability worldwide. Interestingly, iron overload is never observed in cystic fibrosis contrarily to others chronic respiratory diseases. Moreover, iron deficiency reported prevalence in CF is very high (up to 60% in retrospective series) and is correlated to an alteration of respiratory function. Cystic fibrosis patients should be tested annually for iron deficiency. Serum ferritin is the best diagnosis tool for iron deficiency (specificity 87% for a threshold < 30 µg/L). Previously published studies used less performant markers such as serum iron (< 12 µmol/L) or transferrin saturation (< 12%), which are markedly influenced by the systemic inflammation. CF patients experiences frequent pulmonary exacerbations leading to systemic inflammation: iron stores should therefore be assessed at optimal time with no inflammation. The I-MUCO study aims to determine the exact prevalence of iron deficiency in CF patients. We aimed to identify risk factors for iron deficiency onset.
The study investigators hypothesize that Clostridium butyricum and Clostridium neonatal will be more frequently found in the stool of preterm infants with ulcerative necrotizing enterocolitis compared to healthy matched control infants. Systematic daily samples should show that the kinetics of colonization precedes the onset of the pathology. Finally, the systematic ecological survey at the time of infection could help understand the mode of acquisition and transmission of these bacteria.
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.
Chronic urticaria affects up to 1% of the population. Chronic urticaria refractory to updosing antihistamines can benefit from OMALIZUMAB, which is an anti-IgE IgG1 monoclonal antibody administrated every 4 weeks subcutaneously which represents a cost of nearly 800€/month excluding nurse fees. Efficacy and good tolerance have already been demonstrated in real-life large cohorts of patients. A 6 months treatment duration is proposed before evaluating the efficacy and discontinuating the treatment in the absence of adequate response. Mean duration of chronic urticaria is 3 to 5 years with high standard deviations. Therefore, optimal duration of treatment with OMALIZUMAB is unknown and discontinuation modalities differ between physicians. The aim of this study is to evaluate the mean duration between initiation and first discontinuation of OMALIZUMAB in patients treated for chronic urticaria and explore the different factors influencing this duration and its outcome.
Xerostomia is defined as the subjective sensation of dry mouth, and may be associated with a reduction in saliva secretion and composition. It is one of the most common complaints found in patients after irradiation in the head and neck area. This complaint is found in a large majority of patients during radiotherapy, continuing for several years after stopping radiotherapy (93% during radiotherapy and 40 to 60% after two years post-radiotherapy). The advent of IMRT (Intensity-Modulated Radiation Therapy) has reduced this complaint, but it still concerns 40% of patients undergoing post-radiotherapy affecting the head and neck. Xerostomia is responsible for pronunciation difficulties, dysphagia, dysgeusia, alteration of the oral condition leading to a significant alteration of the quality of life. This complaint is maximal in the first six months following radiotherapy, then stabilizes or even regresses in the year following radiotherapy but can persist well beyond the end of the irradiation. At present, there are few treatments that have been shown to be truly effective. Systemic treatments (sialogues, cholinergic agonists, parasympathomimetic and muscarinic agonists, corticosteroids, etc.) allow partial improvement with delayed and not prolonged effectiveness. Many studies evaluating the efficacy of these therapies have shown contradictory and insufficient results (less than half of the patients present an improvement under treatment), without ever allowing a complete cure. Surgical treatments by submaxillary gland transfer have also been studied, but at the price of significant morbidity (cervicotomy, risk to the chin nerve in post-radial areas, etc.). Conformational radiotherapy with intensity modulation has made it possible to reduce the severity of xerostomia but does not make it possible to free oneself from this complication. Patients often find themselves reduced to symptomatic adjunctive treatments (gland massage, sprays, hydration, acupuncture...) without curative treatment. There is therefore a real need to respond to the complaint expressed by many patients by proposing an effective and long-lasting therapy.
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 objective of this study is to collect data from a large cohort of individuals with DMD and BMD focusing on the neurobehavioural aspects of these conditions and their correlation to the location of the DMD gene mutation.
