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 study aims to analyse, in vivo, the interplay between microglial activation and tau pathology in Alzheimer's disease (AD) using [18F]-DPA-714 and [18F]-Ro948 tracers by Position Emission Tomography (PET), and their consequences on synaptic density using [11C]-UCB-J, a recent PET radioligand. By coupling advanced neuroimaging techniques in AD patients, while comparing them to controls, we will be able to study, for the first time in humans, the interaction between neuroinflammation, tau pathology, synaptic density, and their impact on AD progression. Joint analyses of peripheral immune biomarkers, carried out as a secondary objective, will further aim at defining peripheral correlates of this interplay. Overall, we aim to refine AD subgroup classification in order to improve and to refine the design of new therapeutic trials.
Motor learning is crucial for human daily routine, involving the acquisition of new movements. It consists of an online acquisition phase followed by offline consolidation, where motor memory is organized into stable representations. Acquisition can be achieved through physical practice (PP, overt repetition of movement) or mental rehearsal using motor imagery (MI). Recent studies suggest that high-intensity interval physical exercise (HIIE) enhances motor learning, particularly during consolidation, by promoting neural plasticity mediated by brain-derived neurotrophic factor (BDNF). However, the impact of HIIE on sequential motor consolidation with PP or MI remains poorly understood. In contrast, sleep deprivation (SD) reduces BDNF release and neural plasticity. Limited research has explored the effects of SD on motor acquisition, especially sequential motor learning. Considering the opposing effects of HIIE and SD, performing HIIE after SD may protect motor consolidation processes. This study aims to examine the influence of HIIE on sequential motor learning using PP or MI under both sleep-deprived and normal sleep conditions. Six groups, each comprising 12 participants, will learn an 8-item bimanual sequence. - MI group: acquired the motor sequence mentally during training - MI+HIIE group: acquired the motor sequence mentally and achieve a HIIE before the consolidation - PP: acquired the motor sequence physically - PP+HIIE group: acquired the motor sequence physically and achieve a HIIE before the consolidation - SD+PP group: one night of sleep deprivation prior physical motor acquisition with PP and consolidation - SD+PP+HIIE group: one night of sleep deprivation prior physical motor acquisition and HIIE before consolidation. All groups will be tested on the sequence at the beginning and the end of the acquisition phase (pre- and post-acquisition), and after the physical exercise (i.e. HIIE) or the rest period (post-exercise). Hypothesis of this study are : - Acute physical exercise (HIIE) would enhance the consolidation of motor memory (post-exercise) after physical and mental acquisition (PP,MI) compared to conditions without exercise. - One night of sleep deprivation would affect the acquisition and consolidation of motor learning. Physical exercise would compensate for the detrimental effects of sleep deprivation on the consolidation of motor learning.
This Phase 2, randomized, double-blind, multicenter, induction and maintenance study is designed to evaluate the safety and efficacy of RVT-3101 in adult participants with moderate to severe active Crohn's disease.
An evaluation study of the impact of the Axomove Therapy® medical device on subacute or chronic low back pain patients leaving rehabilitation centres to facilitate self-rehabilitation. A prospective, randomized, open-label, multicentre study whose main objective is to evaluate the effectiveness of the Axomove Therapy Medical Device on disability reduction (Oswestry disability index score) patients with subacute or chronic low back pain requiring rehabilitation.
Heart failure reaches 1.5 million people in France and is responsible for 200,000 hospitalizations per year. Over the past ten years, new therapies have emerged (treatment of martial deficiency, Entresto, iSGLT2). Hospitalization in a context of acute heart failure is a moment of choice in the history of the disease to introduce recommended treatments under closer supervision (clinical, biological) than in ambulatory, and allows a decrease in hospitalizations, morbidity and mortality. The purpose of this study is to describe the introduction of heart failure drugs (including iSGLT2) in real-life settings in patients hospitalized for decompensated heart failure.
The appearance of revascularization edema of the lower limb is a frequent complication in peripheral vascular surgery. It can lead to a delay in healing and even to trophic disorders. The prevention and treatment of this complication have so far been limited to postural measures (elevation of the limbs), in the absence of other recommendations and given the contraindication of elastic compression. Inelastic compression is another mode of compression sometimes used in the treatment of lymphedema. It exerts a stable continuous pressure regardless of the patient's position. The investigator's aim is to demonstrate that compression with inelastic bands, applied under good conditions, does not have a major effect on distal arterial vascularization in arterial patients who have undergone revascularization by supra-articular bypass or endovascular treatment of the lower limb.
The goal of this clinical trial is compare the quality of sexual life at 6 months after tubal ligation, depending on whether it was performed by abdominal laparoscopy or by vNOTES, on the basis of a non-inferiority hypothesis. Participants will answer on the FSFI-19 questionnaire and quality of sexual life will be evaluated according to the score obtained at 6 months post-operative compared to pre-operative.
The goal of this clinical trial is to evaluate the impact of a phone call before the simulation CT scan in management of care of patients with prostate cancer.
Febrile neutropenia (NF) is a common serious complication of cancer chemotherapy. Outpatient management of chemotherapy treatments is made essential by the volume of patients treated, respect for their quality of life and the lack of hospitalization resources. The prevention of NF is well documented and its success depends on the risks of developing NF related to the type of chemotherapy protocol used and the profile of the patient and his disease. Pegfilgrastim (G-CSF, biosimilar medicine) injection has been shown to prevent (febrile) neutropenia. It is routinely prescribed on an outpatient basis for patients treated with chemotherapy (CT), several thousand times a year in our geographical area. In order to take into account patient preferences and help clinical decision-making, this study will be conducted on the basis of self-administered questionnaires. The aim of the research is to assess patient preference for receiving administration of PELGRAZ (Accord Healthcare) using a prefilled syringe or a prefilled pen device. In a second step, this study will evaluate the learning of the patient and his autonomy during a pen self-injection guided by a nurse.
Accidental dural puncture is an uncommon complication of epidural analgesia and can cause postdural puncture headache.
