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 project proposes to adapt monthly the existing ICOPE (Integrated Care for Older People) MONITOR program for elderly myeloma patients. This adaptation aims to detect earlier functional decline and prevent loss of autonomy.
The goal of this observational study is to identify diagnostic and prognostic biomarkers for endometriosis using menstrual blood, an easily accessible yet overlooked biological fluid in women of reproductive age, affected or not by endometriosis The main questions it aims to answer are: - are there relevant differences in the menstrual blood of women affected by endometriosis compared to women without endometriosis? - do some of these differences disappear or lessen when the disease is treated by surgery? Participants will answer questions relevant to endometriosis and provide menstrual blood 1 to 3 times (self-collected with a menstrual cup). A subgroup of participants affected by endometriosis that will undergo surgery for their regular care will provide menstrual blood before and after their surgery. Researchers will compare the menstrual blood of women with and without endometriosis, and before and after surgery to see if they can identify significant differences.
Crohn's disease (CD) belongs to chronic inflammatory bowel diseases (IBD) affecting over 2 million individuals in the North America and 3.2 million in Europe with an increasing incidence rate in newly industrialized countries experiencing a westernization of lifestyle (1). This highly disabling disease affects patients' life in several ways with severe complications requiring surgery for half of them and is responsible for considerable economic burdens (2,3). Decades of research displayed that CD pathogenesis is determined by inappropriate immune responses towards luminal microbiota in genetically susceptible hosts. Genome-wide association studies (GWAS) have identified autophagy as one of the main pathways associated with susceptibility to CD (4-6). Autophagy is a dynamic process of the lysosomal catabolism, called autophagy flux, which is crucial to degrade and recycle obsolete and deleterious cytosolic components of the cell (7). Autophagy is also the main cell-autonomous process to fight intracellular microorganisms by degrading them, and by contributing to antimicrobial host immune responses. However, the functional consequences of polymorphisms affecting autophagy-associated genes on the dynamic process of autophagy and its real impact on CD pathogenesis remain largely unknown. In addition, CD is associated with a gut microbiota dysbiosis, as exemplified by the higher prevalence of AIEC (a bacterium eliminated by autophagy) in ileal mucosa of CD patients (8-10). Hence, autophagy defect, linked to autophagy SNPs, could contribute to CD-related dysbiosis and to CD activity and severity. Beyond, CD-associated abnormalities of the autophagy flux may affect the composition of the autophagic cargoes, as well as the one of other vesicular pathway, such as exosomes, known to influence autophagy. These impairments could affect at longer term both cell activities and immune responses, especially in antigen presenting cells, which drive host immune responses. The TOPIC project concerns translational research, in which we plan to generate a prospective cohort of CD patients giving up the unique opportunity to collect clinical data, to analyse simultaneously the autophagy flux, genetic variants of interest (from blood samples) and intestinal microbiota (from intestinal samples) and allowing to perform more fundamental studies. The results of the fundamental part will allow a better understanding of the pathophysiology of CD, and ultimately better management of these patients.
The goal is to perform a first evaluation of the capabilities of a new generation of non-invasive magnetoencephalography whole head device using optically pumped magnetometers using Helium 4 as the sensitive element (OPM He4) to record brain magnetic activities. The investigators will record 1) healthy subjects stimulated with visual, auditory, somesthesic and motor stimuli and 2) athletes who suffered a mild concussion. The main hypothesis is that the OPM magnetoencephalographs (MEG) system will be able to detect brain activity. The secondary hypothesis is that the data recorded with the OPM MEG system will allow to reconstruct maps of the brain activity. To test the main hypothesis, they will compare the signal to noise ratio of brain activities between a classical MEG system and the new OPM He4 MEG. The secondary hypothesis will be tested through a comparison of the maps of brain activity obtained thanks to the data recorded with a classical MEG system and the new OPM He4 MEG.
This is a multicenter genetic study aimed at identifying new genes/variants associated with sudden infant death syndrome (SIDS) based on whole-genome sequencing of family trios
This study will evaluate orally administered RVU120, a novel small molecule Cyclin-dependent Kinase (CDK) 8/19 inhibitor, in terms of erythroid hematologic improvement (HI-E) and safety in participants with lower-risk myelodysplastic syndrome (MDS). Responding patients are eligible to continue treatment until loss of response/disease progression.
The aim of this study is to describe, using a non-interventional survey, the relevant aspects of health in adults with ADRD for the patients themselves, their carers and healthcare professionals. Commonalities and differences between these three stakeholders and according to the severity of the dementia will also be studied.
Immune checkpoint inhibitors (ICIs), such as anti-PD-1/PD-L1 agents, initially evaluated in advanced non-curative pathologies, are now being evaluated in adjuvant or even neoadjuvant curative treatment conditions. This paradigm shift is leading to the treatment of young women, particularly in the context of gestational trophoblastic tumours. Given the potential autoimmune side-effects affecting endocrine functions, as well as their impact on maternal-foetal tolerance mechanisms, accurate assessment of post-ICT fertility is necessary. In the coming years, treatment with anti-PD-L1 (avelumab) could become a cornerstone of the therapeutic strategy for patients with gestational trophoblastic tumours. However, these patients are often young and of childbearing age, so safety of use in terms of fertility and successful pregnancies is an essential factor in the widespread use of immunotherapy as a treatment option. Some studies have reported the possibility of conceiving after avelumab treatment, but no cohort has been reported. This study aims to explore fertility and the course of potential pregnancy in 50 patients treated with anti-PD-L1 (avelumab) over the last 5 years in several French centres.
Fibula free flap is the gold standard for mandibular reconstruction. The shape of the fibula requires osteotomy that can be performed with a custom surgical guide. The use of surgical guide shorten surgical time, enhances the precision of the surgeon and reduces morbidity. Since 2008 custom surgical guide have been used in the hospital department and the clinical team have noticed a number of elements, which leads investigator to think that it would be possible to perform this kind of procedure using an universal guide. The aim of this study is to assess the possibility to perform mandibular fibula free flap reconstruction with an universal guide.
Peripheral arteriopathy disease (PAD) affects 1 million people in France. In its most advanced stage: chronic permanent ischemia also called critical ischemia, the prognosis of patients is burdened with a one-year mortality rate of 30%. Chronic permanent ischemia results from a lack of oxygen supply to the microcirculatory network, responsible for tissue death and the development of trophic disorders. In this context, many studies have focused on the contribution of hyperbaric oxygen therapy, however none demonstrates with certainty its beneficial effect with a heavy set-up for teams and patients. Furthermore, it appears that normobaric oxygen therapy could have its place in this context by temporarily restoring a sufficient level of transcutaneous oxygen. However, even if normobaric oxygen therapy is common practice although empirical for some practitioners, no data demonstrates its real interest. The purpose of this study is therefore to report the proportion, in usual practice, of patients with permanent chronic ischemia of the lower limb(s), benefiting from normobaric oxygen therapy, but also to show the interest of the contribution of this therapy in usual comprehensive management of these patients. This is a pilot study, after which, if the hypothesis is confirmed, it may be proposed to carry out a randomized study, on a large scale, in order to validate the use of normobaric oxygen therapy in the context of chronic permanent ischemia.
