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 evaluate direct costs of Venous Leg Ulcers (VLU) management when two different compression systems are used.
The goal of this study is to evaluate the effects of deferiprone, an iron-chelating drug, in patients with Parkinson's disease. Participants will be randomized to receive one of four different dosages of deferiprone or placebo, and will take the assigned study product twice a day for nine months.
The Radial Artery Deviation And Reimplantation (RADAR) technique is a new approach for the construction of hemodialysis arteriovenous fistula. In this technique, the radial artery pedicle is deviated towards the minimally dissected cephalic vein at the wrist. The aim of this study is to compare the safety and efficacy of this technique with the traditional end-cephalic to side-radial arteriovenous fistula, currently used as a first line vascular access in hemodialysis patients. The hypothesis is that the minimal dissection concept used in the RADAR inhibits venous juxta-anastomotic neointimal hyperplasia and stenosis, and lead to higher rates of maturation and patency.
The main objective of the study is to evaluate the effect on intestinal permeability of a supplementation with Lactibiane Tolérance® for 4 weeks (28 days) in patients suffering from irritable bowel syndrome (IBS) with diarrhea predominance. Secondary objectives of the study are to evaluate the effects of supplementation with Lactibiane Tolérance® for 4 weeks (28 days) in patients suffering from IBS with diarrhea predominance on intestinal permeability, inflammation of the digestive tract, symptoms and comfort. Single-center study in single open arms: 30 volunteer adults suffering from Irritable Bowel Syndrome (IBS) with diarrhea predominance and matching the criteria of inclusion and non-inclusion listed below.
The evaluation of the impact of environment on the incidence of cancer is a major public health issue. Increased knowledge in this area is necessary for the implementation of primary prevention means with appropriate preventive measures but also to the implementation of secondary prevention measures with targeted screening actions. Among the environmental exposures that may lead to cancer, mutagenic environments are of major importance, and the causal link between environmental genotoxicity and cancer has been established for a long time. It is also well established that susceptibility to mutation is highly variable among individuals. This is explained by genetic polymorphisms of genes involved in metabolism and in genome stability. The identification of biomarkers of exposure to mutagenic environments is necessary for assessing the impact of an environment in humans. Some studies in animals have shown that the PIG-A gene may be a biomarker of exposure to a mutagenic environment. In particular, a significant increase in erythrocyte PIG-A mutants has been demonstrated in rats after a genotoxic exposure to cisplatin, but it has so far not been evaluated in humans. One study of healthy volunteers shows that the frequency of PIG-A mutated cells in humans can be estimated efficiently and reliably. The PIG-A gene meets all the necessary criteria for a sentinel gene for tracking of spontaneous somatic mutation frequency or induced a mutagenic environment: ubiquitous expression, phenotypic change linked to a mono-allelic mutation viability of mutated cells , spectrum off inactivating mutations (deletions, substitutions, chromosomal rearrangements). Finally, the detection of the disappearance of glycosylphosphatidylinositol on the plasma membrane is easily achievable by flow cytometry.
Investigators sought to demonstrate that the increase in the stroke volume during a dobutamine stress echocardiography might impact the prognosis of a patient addressed for a low flow low gradient suspected severe aortic valve stenosis.
Dystonia is defined as a syndrome of sustained muscle contractions resulting in repetitive movements and abnormal postures. DYT1 is the most common form of genetic dystonia, but the link between genomic mutations and phenotypic expression remains largely unknown. Furthermore, secondary forms of dystonia have highlighted the role of the basal ganglia, particularly the putamen in the pathophysiology of the disease. Experimental results in a genetic model of dystonia in rodents suggest that cholinergic inter-neurons (ACh-I) of the putamen play a critical role in the pathological process of plasticity in the cortico-striatal synapse. However, these results have not been demonstrated in humans.
Description of clinical and anatomical features and long-term follow-up for patients with ALK rearrangement and treated by crizotinib
This study aims to characterize the diagnostic performance of immunological testing of occult gastrointestinal bleeding in stool in the population aged over 75 years with iron deficiency anemia. As secondary objectives, the study aims to: - determine a threshold of positivity optimizing the immunoassay performance for the study population, in accordance with the probabilities of error (false positives, false negatives) and weights (defined by expert consensus) allocated to these errors. - Assess the benefit of a double measure of bleeding (two stools) by immunoassay compared to a single measure.
Background Women with rare diseases resulting in motor disabilities wishing to become mother face a major challenge. The investigators hypothesize that provided with adequate support, they are able to achieve a successful pregnancy and to offer their child a safe family environment. Methods To test this hypothesis, the investigators shall conduct a prospective observational prospective survey of a consecutive series of volunteer pregnant women or mothers of children less than 14 months, with motor impairment, participating in a program of parenting support developed in our institution. Primary outcome: social environment, child development, mother-infant attachment, mother- infant interactions Secondary outcome: social and demographic characteristics, severity of motor impairment, associated impairment, perinatal morbidity for the mother and the infant (composite indicator), emotional status, and the needs expressed by women regarding the level of medical or social care. Analysis The investigators shall describe the distribution of the primary outcome measurements in the subgroup of women with motor impairment related to a rare disease. The investigators shall compare this distribution to the expected distribution in the general population, and to that observed in women with motor impairment unrelated to a rare disease. The investigators shall also study primary outcome measurements as a function of the severity of maternal disability, of the mother's social characteristics and emotional status. The investigators shall also describe the distribution the distribution of perinatal morbidity globally, and as a function of the potential explanatory variables mentioned above. The investigators shall also report on the opinion of women regarding the support they were offered so far, and the support they declare they should benefit from.
