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 aim of the present study is to determine the prevalence of cardiometabolic and infectious disease in La Reunion (french oversea department and region of France). Known or suspected risk factor for these diseases will also be assessed, such as microbiota, cognitive impairement, social inequalities, and genetics.
Keratopathy of patients with aniridia leads to epithelial scarring disorders and a progressive clouding of the cornea linked to this abnormal healing (fibrosis). Treatment with autologous serum is usually undertaken to promote epithelial healing. However, autologous serum does not prevent the formation of fibrosis, whereas growth factor-rich plasma appears to be associated with a reduction in the in vitro expression of fibrosis markers. This study seeks to compare the in vitro healing and anti-fibrotic properties of autologous serum and growth factor rich plasma from aniridia patients and healthy controls.
Non-pathological stress has an adaptive value, allowing a person to prepare for the demands of everyday life and increasing chances of survival in the face of danger. To "cope", the individual responds with behavioural, emotional and cognitive strategies (coping strategies). Coping aims to modify the problem causing the stress (problem-focused coping) or to regulate the emotional responses associated with the problem (emotion-focused coping), or it can be focused on avoidance (psychologically and/or physically avoiding the source of the stress). Coping is therefore not positive or negative per se and the strategies used by an individual can be positively or negatively associated with resilience. Thus, the mechanisms by which coping strategies, whether dispositional or situational, induce resilience or, conversely, the development of symptoms linked to stress and PTSD remain poorly understood. To detect and characterize some of these mechanisms, the present research focuses on high-level capacities closely linked to coping and resilience and involved in stress and psychotrauma, namely cognitive control (notably attentional and executive processes that allow for adaptive control of cognition and behaviour) and emotional regulation (processes allowing the triggering, inhibition, maintenance or modulation of emotions). The global research program includes different studies aimed at analyzing and screening for factors, or complexes of factors, that may be involved in the modulation of PTSD symptomatology in adults, based on a dimensional process-oriented and integrative approach. The present study will examine the relationship between the severity and nature of the symptoms of PTSD (e.g. avoidance) and the different processes considered. The primary objective is to examine the impact of the preferential use of habitual coping strategies (emotion-focused, problem-focused or avoidance-focused coping) on the severity of PTSD symptoms. Another objective is to explore the interrelationships, in the modulation of symptoms, between these (specific) coping strategies and the more general and stable self-regulatory capacities, namely emotional regulation and cognitive control. 50 patients aged between 18 and 65 years, followed for a definite diagnosis of PTSD, will participate and complete a set of self-questionnaires and neuropsychological tests.
In this study, researchers will learn more about a study drug called BIIB080. The study will focus on participants with mild cognitive impairment or mild dementia due to AD. The main question researchers are trying to answer is if BIIB080 can slow the worsening of AD more than placebo. It will focus on what dose of BIIB080 slows worsening of AD the most. To help answer this question, researchers will use the Clinical Dementia Rating-Sum of Boxes, also known as the CDR-SB. - Clinicians use the CDR-SB to measure several categories of dementia symptoms. - The results for each category are added together for a total score. Lower scores are better. Researchers will also learn more about the safety of BIIB080. The study will be split into 2 parts. The 1st part is the Placebo-Controlled Period. The 2nd part is the Long-Term Extension Period. The 2nd part of the study will help researchers learn about the long-term safety of BIIB080, and how it affects the participant's daily life, thinking, and memory abilities in the longer term. A description of how the study will be done is given below. - After screening, participants will first receive either a low dose or high dose of BIIB080, or a placebo, as an injection into the fluid around the spinal cord (cerebrospinal fluid). A placebo looks like the study drug but contains no real medicine. - Participants will receive BIIB080 or placebo once every 12 weeks or 24 weeks. - After 76 weeks of treatment in the Placebo-Controlled Period, eligible participants will move onto the Extension Treatment period, which will last 96 weeks. - In the extension period, participants who received placebo will be switched to high dose BIIB080 every 12 or 24 weeks. - Participants may be in the study for up to 201 weeks, or about 4 years. This includes the screening and follow-up periods. - Participants can continue to take certain medications for AD. Participants must be on the same dose of medication for at least 8 weeks before the screening period. - After the screening period, most participants will visit the clinic every 6 weeks.
Platelet Transfusion Refractoriness is one of the severe complications after multiple transfusions in patients with severe thrombopenia. Platelet Transfusion Refractoriness is characterized by inefficient transfusion and arise from allo-antibodies specific of platelets antigenes, mostly carried by HLA-I molecules.
The primary objective of this clinical investigation is to evaluate acute safety and efficacy of the S.M.A.R.T. RADIANZ™ Vascular Stent System, when used with the BRITE TIP RADIANZ™ Guiding Sheath and SABERX RADIANZ™ PTA Balloon Catheter, to deploy the S.M.A.R.T.™ Nitinol Stent, in the treatment of patients with obstructive iliac or femoropopliteal arterial disease via radial artery access.
Dendritic cells (DC) paly a key role in the induction and chronicity of psoriasis by capturing the antigenes and activating the T cell repsonse. This activation requires their migration from the cutaneous sensitisation site to the lymph nodes. This migration requires an important intracellular metabolic activity, with a strong involvmenet of glucdic metabolism. This activity is linked with the systemic activity. This study aims to compare the migration and the phenotypic and metabolic caracteristics of blood and skin DCs in patients with or without psoriasis and with or without type 2 diabetes,
This study involves young adults from the PRALIMAP-INES trial and student volunteers from the University of Lorraine, who are overweight or obese. For young adults from the PRALIMAP-INES trial, the proposed research is a continuation of the PRALIMAP-CINeCO research (part 1). For students at the University of Lorraine, the proposed research is aimed at volunteer students who are overweight or obese, via the University of Lorraine's Student Health Service (SSE). Young adults and overweight or obese students not receiving medical care at the time of the inclusion visit (4th measurement time for PRALIMAP-INES participants and 1st time for others) will be offered the chance to take part in a randomized trial comparing the acceptability of health e-coaching versus referral to standard care. Experimental group: health e-coaching Control group: usual care system Primary objective : To determine the effectiveness of an e-health coaching intervention using new technologies that promotes changes in eating and physical activity behavior in overweight and obese young adults aged 20, an intervention targeting the development of autonomous self-regulation. Secondary objectives : 1. Determine the acceptability of health e-coaching: acceptability of new technologies (container), acceptability of personalized health e-coaching (content). 2. Determine the effectiveness of health e-coaching on the criteria of corpulence (BMI; body composition), changes in eating behaviors (TCA), emotion management skills and social interaction skills. 3. Evaluate the benefit of health e-coaching alone or combined with the previous intervention received in the PRALIMAP-INÈS trial on primary and secondary endpoints. 4. Evaluate and compare participation in a health promotion program over two life periods (adolescence and young adulthood) for young adults from the PRALIMAP-INÈS trial. 5. Evaluate the effectiveness of health e-coaching (reinforcement of autonomous self-regulation and changes in eating behaviors and physical activity practices/time spent sitting) according to the dose of intervention received by young adults (received-treatment analysis). 6. Determine the cost-efficiency and cost-utility ratios by means of a medico-economic evaluation based on the incremental cost of the e-coaching intervention in relation to the usual care offered by the health care system (ICER: Incremental Cost-Effectiveness Ratio).

The use of simulation is recommended in anesthesiology education. Given a large number of residents, all of them will not be active participants during high-fidelity simulation sessions but will only be observers. To increase the positive effects of the simulation when the learner is in the role of observer, some authors have proposed to strengthen the educational effect through the use of an observer tool that observers must complete by analyzing the progress of the task performed by their colleagues. This is a list describing the set of key points to be achieved. However, data concerning the educational value of these observer tools are limited. Studies on the use of these tools during crisis management training in the operating room assessed by high-fidelity simulation have shown improved learning outcomes for technical skills but no study has evaluated yet their effect on non-technical skills. The effect on these skills can hardly be assessed by measuring the resident's perception or knowledge and an objective assessment of performance is necessary. The objective of this study will be to evaluate if using an observer tool (OT) dedicated to non-technical skills improves the learning of these skills in anesthesia residents during high-fidelity simulation.
