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.
Sleep apnea-hypopnea syndrome (SAHS) is a disorder of nocturnal ventilation due to the occurrence abnormally frequent pauses in breathing. It is a public health problem that currently affects 13 % of men and 6% of women between 30 and 70 years old. Sleep apneas are conventionally divided into obstructive and central apneas, depending on the persistence or no respiratory movements and the existence or not pharyngeal collapse during apnea. There are upper airway characterization studies (VAS) in patients with syndrome sleep apnea/hypopnea (OSAS). These physiological characterization studies (measurement of critical closing pressure (Pcrit) of the VAS) and anatomical (transcutaneous ultrasound of the muscles of the floor of the mouth, the base of the tongue, or by a acoustic pharyngometry of the VAS) are interested separately to different parameters without searching correlation with the severity of sleep apnea nor their potential as a screening tool for OSAS in patients at risk. The investigators hypothesize that a strong correlation and constant exists between the physiological collapsibility of VAS, the anatomical measurements of the VAS and the degree of severity of OSAS. Thus, the aim of this descriptive study is to characterization as complete as possible of the VAS of apneic patients in a homogeneous population and a better understanding of the pathophysiological obstructive events in patients without factor obvious risk.
The goal of this clinical trial is to assess the safety and efficacy of three intravenous injections of the extracellulat vesicle-enriched secretome of cardiovascular progenitor cells in severely symptomatic patients with drug-refractory left ventricular (LV) dysfunction secondary to non-ischemic dilated cardiomyopathy. The main questions it aims to answer are: - Are these repeated injections safe and well tolerated? - Do they improve cardiac function and, if yes, to what extent?
The Toxoplasma gondii parasite causes toxoplasmosis. It is characterized by persistent cysts mostly localised in the brain and ocular areas. In the case of immunodeficiency, those cysts are likely to reactivate. During pregnancy, an infection exposes the foetus to a variety of consequences, from severe neurologic lesions to subclinical forms at birth. However, those forms are likely to complicate at any age to toxoplasmic retinochoroiditis, that can unpredictably recur with severe functional consequences. Pregnancy may stimulate lesions or their recurrences, putting the foetus at risk of contamination because of the release of tachyzoites in the bloodstream. The occurrence of these complications is poorly known, especially with congenital toxoplasmosis. Nevertheless, this information is essential to take care of patients, particularly women with congenital toxoplasmosis, usually worried about the consequences of a pregnancy. As a precaution, women with congenital toxoplasmosis follow a specific ophthalmologic, and trimonthly monitoring, composed of fundus examinations during pregnancy and in postpartum. To eliminate the contamination risk, serological examinations at birth and one year later are done on their kids. The aim of this study is to estimate the risk of toxoplasmic retinochoroiditis during pregnancy and the impact on their children. Retrospective and prospective data from the Lyon Cohort of Maternal and Congenital Toxoplasma Infections will be used. As a result of to this study, the investigators expect to provide better information to women suffering from congenital toxoplasmosis about their own ocular safety during pregnancy, and the safety of their child(ren). The investigators seek to provide new national and international recommendations about these patients and their children's care.
The aim of this study is to understand and interpret the determinants that lead pregnant women to refer more to a health professional in order to better meet the patient's request.
Narcolepsy is a chronic disabling neurologic disorder mainly characterised by excessive daytime sleepiness. Type 1 narcolepsy is associated with a deficit of hypocretin in the cerebrospinal fluid responsible for the cataplexy symptom while type 2 shows a normal hypocretin level and no cataplexy. While the development of narcolepsy is independent of parental social level, narcolepsy has a significant influence on educational level, grading, social outcome, and welfare consequences. Several studies assessed global cognition efficiency, mood, and attention in narcoleptic patients but only a few specifically measured social cognition and mostly without a control group. In a population of narcoleptics children, a severe impairment in social cognition is described for 20% of the group, contrary to 2 % for the control group. The literature also depicts some impairments in decision making, somatic and cognitive emotions responses but the emotion recognition seems to be preserved. A better understanding of the social and cognitive aspects of narcolepsy could lead to a better treatment of the disease in its entirety, including if relevant specific cognitive behavioural therapy. The protocol consists in a psychometric evaluation including several questionnaires in order to assess social cognition. It will be proposed to patients with type 1 or type 2 narcolepsy and patients with idiopathic hypersomnia.
Due to increasing of life expectancy, patients with von Willebrand disease are exposed to age-related pathologies such as cancer or cardiovascular diseases. Management of thrombotic events is challenging given the inherent bleeding risk in von Willebrand disease. Few data are currently available in the literature. The aim of the study is to describe the frequency and nature of arterial and venous thromboembolic events and atrial fibrillation in patients with von Willebrand disease in the West of France. The investigators will perform a retrospective multicenter study conducted in the von Willebrand population of the French West. Von Willebrand adult patients followed in one of the French West medical centers participating in the study, who presented deep vein thrombosis, pulmonary embolism, ischemic stroke, transient ischemic attack, acute coronary syndrome, acute limb ischemia, atrial fibrillation, arteriopathy of the lower limbs, angina will be eligible.
The aim of the study is to compare the skeletal and dental maxillary expansion obtained with an Hyrax tooth-borne expander anchored either on the 2nd deciduous molars (V) or on the 1st permanent molars (6)
Laparoscopic appendectomy is a very common intervention in pediatric surgery. To improve outcomes, some teams have developed the use of single-site laparoscopic appendectomy (SILAP). Nevertheless, there is no consensus yet and no published data on the better perioperative analgesia, and different modalities including general intravenous analgesia, locoregional pre-operative analgesia and local analgesia can be used.
The aim is to evaluate the effectiveness of the device (emergency kit and video-medical control in emergency call centers) in reducing deep night hospitalizations of elderly people living in retirement homes.
Mixed qualitative and quantitative study, in two phases: Creation of a self-rehabilitation program based on people's daily living activities and designed with and for them. Randomized controlled study to explore whether there is a potential benefit for patients with chronic stroke to use a self-rehabilitation program.
