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 rationale of this research is to determine if patients with lupus and presenting retinal "pseudo-drusen-like" deposits have genetic and complement-related similarities with AMD patients. Based on the results obtained, this study could lead to future research that could better target the treatment of patients with lupus or patients with AMD (Age related Macular Degeneration). The primary objective is to check if patients with lupus, treated or not with antimalarial drugs, with "pseudo-drusen-like" deposits have a different complement profile (functional exploration of complement, complement factors, genetic complement polymorphisms involved in AMD) compared to patients without "pseudo-drusen-like" deposits.
Foot surgery is a painful surgery that is usually scheduled in outpatients. A good management of analgesia is the crucial point. Regional anesthesia (RA) is the gold standard, that provides good anesthesia and a long duration of analgesia. The sciatic nerve block (or its branches) is the most adapted analgesic technique. Limitation of proximal sciatic block is the motor block of the ankle and results in the impossibility, for the patient, to walk during the early post-operative period. Distal block of the sciatic nerve (tibial and fibular nerve blocks), at the level of the ankle, has been proposed to maintain the mobility of the ankle, to make deambulation with crutches easier. Nevertheless, the lack of sensibility of the heel remains a limitation for early walking, even with adapted shoes (ie : Barouk). A specific anesthesia of the distal part of the foot, respecting the heel, could be the best option to provide an early deambulation and a suitable analgesia. Ultrasound identification and specific anesthesia of the branches supplying the distal part of the foot (medial and lateral plantar nerves) could meet this dual objective : good anesthesia and suitable analgesia for early deambulation. This study is a feasibility study of a specific block of the plantar branches of the tibial nerve, to preserve the sensibility of the heel, in case of foot surgery. The safety of the procedure will be assessed according to the rate of postoperative dysesthesia.
A prospective, multicenter, open label, randomized phase III study to evaluate efficacy and safety of FFX versus CPI-613 + mFFX in patients with metastatic adenocarcinoma of the pancreas with age range of 18 to 75 years
Approximately 2000 patients eligible for elective treatment with a Carotid Stent according to hospital routine practice in centers across Europe will be enrolled in the study. The maximum number of patients enrolled at each site will be not limited. Follow-ups are scheduled at discharge, 30 days, and 1 year, as per local practice. Each patient will have follow-up contacts via hospital visit and/or telephone.
Hypertension is common disorder after renal transplantation and is associated with mortality. Calcineurin Inhibitor (CNI), by activating NCC cotransporter, may be a major determinant of hypertension, included in a "Gordon like" syndrome. However, prevalence of NCC activation by CNI is unknown. Our objective is to determine the prevalence of NCC activation three months after transplantation in patient treated by CNI.
Elucidating the structure-function relationship of the brain is one of the main open questions in neuroscience. The capabilities of diffusion MRI-based (dMRI) techniques to quantify the connectivity strength between brain areas, namely structural connectivity (SC), in combination with modalities such as electroencephalography (EEG) to quantify brain function have enabled advances in this field. However, so far the actual relationship between SC measures and measures of information transport between neuronal patches has not been determined. In this project, we aim to establish a relationship between dMRI SC measures, direct measures of electrical properties of the human brain cortex obtained with electrocorticography (ECoG), and response elicited by direct electrostimulation of the brain (DES). Ten patients operated on awake surgery for brain tumor removal will be included. First, a dMRI will be acquired prior to the surgery, in order to extract SC indices through probabilistic tractography. Then, intrasurgical cortico-cortical electrical measures will be obtained by ECoG electrodes positioned on the predefined cortical terminations of the designated bundles. These measures will be correlated to functional responses obtained during the cortical cartography, following the common DES procedure. The results of this multi-modal approach combining structure and function explorations of the brain should help to elucidate the relationship between non-invasive (dMRI) SC measures and cortico-cortical transmission properties (delays, transfer functions), and should boost the understanding of cognitive function as well as neurosurgical planning for the treatment of pathologies such as brain tumor resection and drug-resistant epilepsy.
Assessment of the mutational profile of the residual clone and the distribution of lymphocyte subpopulations at 3 years of treatment with ibrutinib This project has an epidemiological part: to establish the percentage of patients, in a real-life situation, still undergoing treatment 3 years after its initiation, as well as a biological part: to determine the evolution of the clone and the prevalence of BTK mutations and PLCg2 in the absence of clinical or biological criteria for scalability.
The purpose of this study is to determine if tofacitinib is safe and effective in subjects with active ankylosing spondylitis.
The possibility of exploring the lungs by lung ultrasound, a non-invasive tool, is becoming increasingly popular for anesthesiologists. Recently, Lichtenstein has described the FALLS protocol (Fluid Administration Limited by Lung Sonography) which uses the potential of pulmonary ultrasound to evaluate early pulmonary overload due to fluid administration at a subclinical stage. Indeed, fluid administration can generate a sub-clinical interstitial syndrome that can be detected by passing from a profile A to a profile B in lung ultrasound. The transition from a profile A to a profile B therefore corresponds to the transition from a state of preload dependent to a state of preload independence. However, this tool has not been studied in the operating room. The main objective of this study will be to study the correlation between pulmonary ultrasound and SV variation measured by esophageal Doppler during fluid administration in patients with haemodynamic optimisation in the operating room during digestive, urological, gynecological and orthopedic surgeries. The main expected result is the following: good correlation between the absence of increased SV in the esophageal Doppler and the appearance of a B-profile lung ultrasound fluid administration in the operating room.
Familial hypercholesterolemia (FH) is an autosomal dominant genetic disorder characterized by elevated plasma levels of LDL-C cholesterol. This early and significant elevation of LDL-C triggers premature atherosclerosis, particularly coronary artery disease. The initiation and management of LDL-C therapies is based on cardiovascular risk assessment. Although this is undoubtedly higher than in normocholesterolemic patients, a significant heterogeneity in heFH patients still persists that is not completely explained. Moreover, the evaluation of cardiovascular risk in patients with heFH is difficult for many reasons: non-validity of risk scores, futility of a risk calculation limited to 10 years in a young patient, late positivity of stress tests . Therefore, there is a clear need for new cardiovascular risk assessment tools to identify higher risk heFH patients who could benefit from early and aggressive treatment. The Coronary Artery Calcium (CAC) Score has been widely studied in the US and validated in European recommendations, and has shown the best reclassification index for patients at intermediate cardiovascular risk. A CAC score of zero is associated with a very low risk of event irrespective of the number of risk factors. Non-calcified plaques are by definition not detected by ACC and patients with CAC = 0 may only have soft non-calcified plaques. The prevalence of these non-calcified plaques in very high-risk patients with acute coronary syndrome is 5%. The prevalence in FH patients is unknown. It has also been shown that the extent of the atherosclerotic burden is related to cardiovascular risk. CAC score has been poorly evaluated in heFH patients. However, hypercholesterolemia and calcifications have been shown to be correlated: supra-aortic calcified masses in homozygous FH patients, early calcifications associated with chronic exposure to high LDL-C (cholesterol burden, equivalent to cigarettes) and finally, the calcifying role of statins. The early increase of LDL-C in patients with genetic forms of FH causes premature cardiovascular damage. Investigators' hypothesis is that patients with FH have earlier coronary atheroma (and thus calcifications and non-calcified plaques) due to exposure early in life to high levels of LDL-cholesterol.
