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.
Through this phase IV study, multicenter prospective exploratory, uncontrolled, the investigators propose to identify MRI predictive factors of treatment response, using diffusion MRI sequences, in addition to conventional sequences. The primary objective is to study the links between changes on MRI diffusion and response to treatment with Tysabri to 2 years. The secondary objective is to compare the evolution of diffusion MRI data with the volumetric MRI data.
This study aims to demonstrate that presurgical assessement of patients' risk factors and surveillance during surgery, both performed by nurses, are not inferior to anesthetic team's care, concerning the rate of complications in cataract surgery with topical anesthesia. The nurse performs the triage of patients based on a chart of risk factors assessment. The triage, according to the presence or not of risk factors, leads to patients' care by an anesthetic team (medical anesthesist for pre-surgical assessement and anesthetic nurse for surveillance during surgery) or to patients' pre-surgical assessement and surveillance during surgery both performed only by nurses. In the control group, all patients are taken care of by an aesthetic team, with medical pre surgical assessement and surveillance during surgery both performed by anesthetic nurses.
Sepsis remains a major cause of death in developed countries. A better understanding of the mechanisms involved in the regulation of inflammatory and immune response of patients with severe sepsis is an important step that could open the way for new therapeutic approaches.
The dimethyl fumarate is an oral drug, indicated in the treatment of the relapsing-remitting multiple sclerosis (MS) , which efficacy and safety has been assessed and validated in two randomised, placebo phase-controlled III international studies, organized by the pharmaceutical company developing the molecule. TECFIDERA® (dimethyl-fumarate) has received European approval on January 30, 2014, for the treatment of adult patients with relapsing remitting MS. Treatment with dimethyl fumarate is introduced as part of the usual care under supervision of a physician experienced in the treatment of the disease. It has proved effective to reduce the number of relapses in patients with recurring-remitting MS and reduce the number of patients who have relapses during treatment. The objective of the study is to observe, in real conditions, on the one hand the tolerance and the other evolution, clinical and radiologic disease in patients already treated by dimethyl-fumarate and collect long-term safety data.
The aim of the research is to detect prematurely vulnerable patients needing a global coverage in integrated care with a created and metrological validated score.
The objective of this study is to compare two methods of pelvic floor muscle training: reference method versus CMP ® method ( (Connaissance et Maîtrise de Périnée : Knowledge and Control of Perineum)
Femtosecond laser-assisted cataract surgery consists in nuclear lens fragmentation, followed by ultrasound phacoemulsification of nuclear lens, which is then removed. It can be assumed that fragmenting the nuclear lens in more pieces could facilitate the post-laser ultrasound phacoemulsification to extract the lens, with a lesser amount of ultrasonic energy. The decrease of ultrasonic energy delivered during cataract surgery is beneficial to the patient because it optimizes the vitality of corneal endothelial cells, which ensure corneal transparency.
HIV-infected patients with intermediate-high risk have a high prevalence of CAD and a substantial proportion of obstructive CAD. Degree of stenosis is associated with immunoactivation (lymphocyte and monocyte) and microbial translocation
The link between the products of synthetic chemistry and cancer is at the heart of much research. Recent work has identified the use of plant protection agents by farmers as a risk factor for developing non-Hodgkin lymphoma, including diffuse large B cell lymphoma (DLBCL) is the most common histology. Different biological models were used to understand the role of pesticides in lymphomagenesis. To summarize, most pesticides act at the cellular and molecular level, on different signaling pathways. After metabolized by cytochrome P450, these compounds generally become pro-oxidants. The increase in reactive oxygen species rate (SAR) causes the activation of signaling pathways involved in cell proliferation and survival. But deregulation of oxidative status does not in itself justify the specificity of the impact of pesticides on specific pathologies. Several agents have a genotoxic effect, others induce the activation of signaling pathways by binding to transcription factors and others have immunomodulating properties.
TB remains a health problem in France with about 5,000 new cases per year. Development of new screening tests is a priority for TB. The main objective of the study is to evaluate performances of innovative blood tests to identify active tuberculosis in adults patients living in low-prevalence country. Adult patients with possible TB from will be tested for the presence of antibodies directed against M. tuberculosis selected antigens. Positive and negative predictive values will be established based on TB culture results.
