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 main hypothesis is the nicotine is associated with a modification of retinal micro-vascularization. Patients will be recruited during their ophthalmologic consultation at the Rothschild Foundation, an OCT-A will be realized and data relating to medical history, oral contraceptive intake and nicotine consumption via cigarette or e-cigarette data will be collected. The objective is to seek an association between retinal vascular density and inhaled nicotine intake.
The hypothesis is that in patients with stroke, abnormalities of retinal microvascularization shown on color fundus photography and the depletion of retinal capillary density evaluated by OCT-A are markers of acute impairment of microcirculation of the central nervous system and are correlated with lesions on brain imaging. Patients hospitalized for stroke MRI-confirmed, will be included. An ophthalmologic assessment including color fundus photography (CFP) and OCT-A will be carried out after stabilization and at 3 months follow-up. Outcomes assessor will be blinded.
Some fibromyalgia patients may use inappropriate emotional regulation strategies to respond to pain. Rumination could be one of this inefficient regulation strategies. The investigators believe that the use of rumination strategies to respond to the discomfort of daily physical activity would maintain and aggravate a negative emotional state after the effort. Distraction would be a more effective strategy to cope with pain. From this data, the investigators want to explore the causal link between rumination and negative affectivity after physical activity in fibromyalgia using an experimental design.
Multicenter, open-label, safety and tolerability study of ascending doses of HepaStem in patients with cirrhotic and pre-cirrhotic non-alcoholic steato-hepatitis (NASH) to determine the safety and tolerability of ascending single and repeated doses of HepaStem administered to patients with cirrhotic and pre-cirrhotic non-alcoholic steato-hepatitis (NASH)
Spaceflight induces detrimental changes in most organ systems with both acute changes and chronic adaptations. For example, acute fluid shifts associated with weightlessness (also called - improperly - microgravity) cause initial rapid cardiovascular alterations, whereas the chronic changes are more reflective of cardiovascular deconditioning and cerebrovascular/ocular adaptations (Pavy-Le Traon et al., 2007). Long-duration stays in weightlessness have resulted in ocular structural and functional adaptations in some astronauts, which has been termed the Spaceflight Associated Neuro-ocular Syndrome (SANS ; see review in Lee et al., 2018). The leading hypothesis is that ocular changes are the consequence of chronic exposure to the weightlessness-induced headward (cephalad) fluid shift experienced by all astronauts. Countermeasures targeted to reverse this fluid shift, including lower body negative pressure and veno-occlusive thigh cuffs, have been proposed and tested in ground-based studies using a head-down tilt model of the cephalad fluid shift. However, the amount of fluid shift reversal required to prevent the development of SANS has not been investigated or determined. Similarly, artificial gravity through centrifugation has been proposed as a SANS countermeasure, given its ability to reverse headward fluid shifts and its efficacy as a countermeasure to long-duration bed rest-induced cardiovascular adaptations (long-duration bed rest is widely employed to simulate the effects of microgravity on various physiological systems). However, the minimum level of artificial gravity required also has not been investigated. The primary objective of this study is to characterize cardiovascular, cerebrovascular, and ocular changes across a range of gravity levels to identify a threshold of gravitational load that can serve as a countermeasure to SANS during future spaceflight missions.
The objective of this research work is two-fold: (i) to conduct a systematic literature review to identify surrogate endpoints in this specific drug class (review registered in the PROSPERO database) and (ii) to assess the surrogate properties of candidate surrogate endpoints in the specific context of melanoma cancer.
The main objective of this work is to validate in French the questionnaire EARS, adapted to chronic low back pain. Physical exercise is often recognized as necessary for primary and secondary prevention and treatment of chronic diseases. This is particularly true of chronic low back pain. It is therefore of paramount importance that compliance with such treatment be assessed to allow for readjustments, as well as drug treatment. No gold standard6-7 measured patient adherence to exercise programs until the creation of the EARS in 2016 by E.Godfrey and his team (Exercise Adherence Rating Scale, literally "joining physical exercise programs") EARS is a reliable and validated psychometric assessment questionnaire that assesses adherence to prescribed physical exercise in chronic low back pain.
Ceftolozane/tazobactam is a new antibiotic with broad spectrum activity. This molecule is currently one of the most active beta lactams against Pseudomonas aeruginosa and its spectrum of activity also includes enterobacteriaceae producing a broad spectrum beta-lactamase (EBLSE). Ceftolozane/tazobactam is currently marketed for the treatment of complicated intra-abdominal infections and complicated urinary tract infections. These intra-abdominal and urinary infections are mainly caused by enterobacteriaceae (Escherichia coli, Klebsiella pneumoniae) and more rarely by P. aeruginosa. Concerning enterobacteriaceae, French epidemiology reports a prevalence of BLSE of between 10 and 15% in E. coli and 10%-30% in K. pneumoniae.
Hepatocellular carcinoma (HCC) is a common tumor (the 8th leading cause of cancer in France) and has a poor prognosis. It is the 3rd leading cause of cancer deaths in the world. In the early stages (low tumor mass), HCC can be treated for curative purposes by surgical resection, percutaneous ablation or liver transplantation. When the tumor mass is larger (> 3 nodules) but remains confined to the liver, the standard treatment is hepatic intra-arterial chemoembolization (TACE). In the event of failure of the latter or if the tumor dissemination progresses in the portal venous system or in the form of metastases, the systemic treatments are then indicated. In 1st line, the reference treatment is a tyrosine kinase inhibitor (ITK) Sorafenib. Cabozantinib obtained the European and French authorization (AMM) in November 2018 for its use in case of failure of Sorafenib in patients with HCC. The main objective is the evaluation of the safety of Cabozantinib administered to patients with intermediate HCC ineligible for chemoembolization or advanced HCC after failure of Sorafenib and possibly another systemic anticancer line.
Colonoscopy is the gold standard for colorectal cancer prevention by allowing the resection of superficial colorectal adenomas or adenocarcinomas. This protection, more effective in the left colon than in the right colon, is imperfect and there are some adenomas and cancers omitted during colonoscopy. The G-EYE colonoscope equipped with an integrated distal balloon would better unfold the haustrations and stabilize the endoscope. Thus, the detection rate of adenomas would be improved by this better vision. The main objective of this study is to confirm that the use of the G-EYE colonoscope allows better detection of adenomatous polyps, decrease the rate of omitted adenomes and then is more effective.
