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.
SITUATION ON RESEARCH Diastolic heart failure (HF) or heart failure with preserved systolic function (SF) is the primary cause of heart failure in the elderly (over 2/3 of heart failure in patients over 60 years). Its main cause is hypertension. The diagnosis of diastolic heart failure is still controversial in clinical practice. It is based on ultrasound and biological criteria (or MRI). Basically, it is concerned patients making acute pulmonary edema with preserved SF and high BNP. It is now recognized that the "primum movens" of this type of HF is increased myocardial stiffness secondary to LVH. Noninvasive assessment of this parameter would allow a more accurate and reliable diagnosis because not dependent on load conditions unlike the ejection fraction (EF) and trans-mitral Doppler. However, the absence of non-invasive tool for the direct evaluation of the diastolic stiffness (so-called passive) prevents to date to use this diagnostic parameter. The investigators propose here to evaluate noninvasively myocardial stiffness in elderly patients with diastolic heart failure using a new imaging tool that uses an innovative ultrasonic technology, the ultrafast echo associated with its elastography function "ShearWave Imaging" (SWI). The investigators work for several years in collaboration with the Langevin Institute on this technology which was recently validated in experimental models. Its principle is based on the creation of a shear wave from a standard ultrasound and calculating the velocity of this wave with the high time resolution of the ultrasound probe, this being correlated with the speed myocardial stiffness. The human study was recently made possible by the development of a phased array probe having the opportunity to work with elastography mode (SWI). PURPOSE OF RESEARCH The goal will be to demonstrate the interest of the non-invasive evaluation by ultrafast echo (SWI) of myocardial stiffness in the diagnosis of diastolic heart failure in the elderly.
NK (Natural Killer) cells are important in the fight against tumor, especially for the control of cancer metastasis. The purpose of this prospective study is to evaluate the impact on lymphocytes NK functions and development of an everolimus treatment in women treated for a metastatic breast cancer. In particular, the study of lymphocytes NK functions and development under everolimus treatment could permit to validate an early biomarker of the impact of everolimus on these NK cells.
The purpose of this study is to determine whether etrasimod (APD334) is a safe and effective treatment for ulcerative colitis after 52 weeks of treatment.
The aim of the study is to prove the efficacy and safety of pallidal DBS in HD patients and to show superiority of DBS on motor function in the stimulation group compared to stimulation-off group
Cataract is the clouding of the lens of the eye, which initially prevents clear vision and eventually progresses to blindness if left untreated. Cataract remains the leading cause of blindness and an important cause of visual impairment across the globe. Cataract surgery by ultrasonic phacoemulsification is the most common surgery practiced in France (600 000/year) Two sub-categories of phacoemulsification coexist : Endocapsulars techniques represented by Divide-and-Conquer and Phaco-Chop ; and Supracapsular techniques mainly represented by Subluxation (similar to Tilt-and-Tumble) The corneal endothelium plays an important role in maintaining the dehydrated state and the transparency of the cornea. Some degree of endothelial cell loss invariably occurs in all types of cataract surgery but the amount of endothelial cell loss may varies with the type of surgical technique The aim of the study is to evaluate the density of the central corneal endothelial cells before and after cataract surgery comparing two phacoemulsification techniques (Divide-and-Conquer vs Subluxation)
Allergy is a very common problem and can be a handicap in everyday life, specially when symptoms occur at work place. Some persons working with drosophila developed respiratory symptoms. Investigators tried to analyze if these manifestations could be due to a specific allergy to drosophila.
Ventilation-associated pneumonia is the main site of healthcare-associated infections in the severe trauma patient, with a mean incidence rate of 35%. Ventilator-associated pneumonia increases morbi-mortality, length of stay in intensive care and overall management costs. As was recalled by the jury of the 2008 SFAR-SRLF consensus conference on the prevention of nosocomial infections contracted in intensive care, success in this preventive endeavour depends on a number of measures: orotracheal intubation route, maintaining tube cuff pressure between 25 and 30 cm H2O, maintaining a semi-seated position ≥30°, nasal and oropharyngeal care at regular intervals, striving to avoid unscheduled extubation, and use of a written sedation-analgesia algorithm allowing for early weaning from ventilation. Devices ensuring continuous pneumatic control of tube cuff pressure are more efficient in maintaining tracheal balloon pressure than intermittent adjustments using a hand-held manometer. In one study, these devices clearly facilitated diminution of microaspiration of gastric contents and of ventilator-associated pneumonia incidence density (9.7 vs. 22 VAP/1000 days of mechanical ventilation; p = 0.005). The investigators are putting forward the hypothesis that by adjoining a device providing continuous pneumatic regulation of tube cuff pressure to an overall strategy aimed at ventilator-associated pneumonia prevention (including semi-recumbent position ≥30°, oro-nasal-pharyngeal care at regular intervals and reduced risk exposure) can decrease VAP incidence by 50% in severely traumatised patients whose condition necessitates mechanical ventilation of an expected duration exceeding 48h. Ours is the first large-scale study to evaluate the interest of an innovative technology bundle on decrease of ventilator-associated pneumonia incidence in one of the intensive care populations the most at risk, namely severe trauma patients, a population presently benefiting from the other recommended preventive measures.
Due to different study designs, the sponsor separated Part C into a separate registration (NCT04958642), leaving Parts A/B here in NCT02534844. This study is to find out how safe and effective VTS-270 is for patients with Niemann-Pick Type C1 (NPC1) disease who have neurologic symptoms (listed under Keywords). In Parts A/B, two out of every three patients will receive the study drug. The third patient will receive 1 to 2 small needle pricks at the location where the LP and IT injection is normally made (sham control). In Part C, all participants will receive study drug, as described in the Part C registration record. Start date for this record is the first day a participant was enrolled in Parts A/B. The trial is actually continuing until the last primary outcome measure of safety data are collected from Part C participants. The last primary outcome measure of safety, along with final adverse events results will be posted in the separate Part C registration record.
The primary objective of this study is to evaluate the effect of presatovir on nasal respiratory syncytial virus (RSV) viral load in RSV-positive lung transplant (LT) recipients with acute respiratory symptoms.
The objective is to study the relation between the reorganization of the central auditory system, and the psychophysical deficits in binaural hearing in subjects with single sided deafness.
