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 goal of our project is the study of subcutaneous and visceral (SAT and VAT) adipose tissue taken during bariatric surgery (Single port sleeve gastrectomy) of subjects with HIV infection, anf morbid obesity with undetectable viral load (VL) and having HIV lipohypertrophy particularly truncal. The study covers both the morphology of adipocytes,fibrosis, immune activation and inflammation, gene expression, pharmacology of antiretroviral drugs (ARV) and the measurement of viral replication in the adipose tissue and the plasma before and after bariatric surgery.
Recent epidemiological studies in France showed a high prevalence of obesity (14.5%) and its strong increase in the last 20 years. Among the many complications associated with obesity, liver complications (steatosis and steatohepatitis [NASH]) are among the most common. Semaphorins were described in the early 1990. More than 20 types of these proteins have been reported to date. These proteins were used for neural development. Since many functions have also been described. The semaphorins are involved in numerous physiological or physiopathological processes (cardiac morphogenesis, vascular growth, tumor progression), the regulation of immune cells and liver fibrosis. Preliminary studies have allowed to show that dendritic cells infiltrate adipose tissue and initiate the activation of T cells and inflammation. Immune semaphorin are new players in the regulation of inflammation and immune reactions. The role of immune semaphorin in regulating inflammation in the two compartments (liver and adipose tissue) could be a crucial step that could lead to more severe liver damage. Its dysregulation could explain NASH injuries. The goal is to identify a new mode of regulation of cellular homeostasis in the fatty liver disease. These factors may serve as diagnostic markers or future therapeutic targets.
The purpose of this study is to demonstrate that the biliary concentration of TCR is a good marker of its immunosuppressive activity.
Although practiced for many years, surgical correction of scoliosis is relatively subject published for idiopathic scoliosis and a few published for other types of scoliosis. This study involves a creation of an observatory of patients undergoing scoliosis by ST2R reduction technique (Simultaneous Translation on Two Rods) associated with the PASS ® system. The main objective is to analyze the three-dimensional correction of the deformity after intervention and its maintenance over time depending on the etiology of scoliosis. This research is conducted in pediatric surgery services specialized in this technique. Correcting radiographic parameters is directly related to the surgical procedure. The quality of life of patients is indirectly affected by the surgery. Secondary objectives are to analyze the surgical technique and to evaluate its impact on the quality of life of patients. This study will firstly to have a better understanding in: - Scoliosis of the children and adolescents and their surgical treatment; - The impact of the surgical procedure by the ST2R technique on the three-dimensional correction, and the patient's quality of life; and secondly, better management of patients requiring surgery for scoliosis as well as a public health impact.
The Exploration Center for Prevention and Treatment of Atherosclerosis (CEPTA, Bordeaux Hospital University) showed that following myocardial infarct (MI) or ischemic stroke (TIA or stroke), the global management (medical and educational) of patients led to very long-term satisfactory results in terms of reduction of cardiovascular (CV) risk and morbidity and mortality. However, the specific effect of therapeutic education beyond the conventional treatment has never been an adequate assessment. The following at 1 year of this study will show the evolution of chronic long-term CV disease in patients who received therapeutic education, and to explain the mechanisms. The challenge of this project is to demonstrate for the first time the superiority of therapeutic education and conventional care and propose a modeling program for national diffusion. Patients who experienced a CV event (MI, stroke) will be randomized into 2 groups of 165 patients each: 1) receiving conventional treatment alone; 2) receiving conventional treatment + CEPTA program. The study was built for a 1-year follow-up period, to demonstrate the impact of therapeutic education on evolution of risk factors, physical, psychological and social health of patients. The main benefit of this study for the patient is the implementation of an optimized treatment and long-term monitoring by a cardiology referral center.
Mild traumatic brain injury (mTBI) is a very common reason for presentation to pediatric emergency departments. So as not to overlook the risk of complications, which occur at a rate of 0-7%, measures such as cranial computed tomography (CCT-scan) and/or short inpatient observation are prescribed. Ultimately, the majority of these measures could be avoided and a large Australian cohort shows that the risk of brain tumors is 2.44 times higher for children who had a CCT-scan (3.24 for age 1-4 years). Assay of a sensitive biomarker in blood, such as the S100B protein, has the potential to reduce the number of these unnecessary measures.
The hypothesis implies that this work is the use of hyperoxia during cardiopulmonary bypass by his heart preconditioning effect is associated with a lower incidence of cardiac arrhythmias (atrial fibrillation, tachycardia or ventricular fibrillation) and lesions of myocardial ischemia-reperfusion injury in cardiac surgery postoperative.
Behavioural disorders are very common right from the initial stage of dementia and contribute to loss of autonomy. Behavioural dysexecutive disorders have a particular status due to their prevalence and their diagnostic importance, as they often constitute the initial symptoms of Frontotemporal Dementia (FTD), Semantic Dementia (SD) and Huntington's disease (HD) and they are classically more frequent in vascular dementia (VaD) than in Alzheimer's disease (AD). The presence of these disorders at the stage of Mild Cognitive Impairment (MCI) has only been partially evaluated and would increase the risk of progression to dementia. These classical data are based on non-standardized assessments and non-validated diagnostic criteria. The Groupe de Reflexion pour l'Evaluation des Fonctions EXécutives (GREFEX) has developed a standardized assessment tool for behavioural dysexecutive disorders, the Behavioural Dysexecutive Syndrome Inventory (BDSI) and has validated diagnostic criteria for this syndrome.
This study was comprised of three substudies. The objective of Substudy 1 was to characterize the dose-response, efficacy, and safety of upadacitinib compared to placebo in inducing clinical remission to identify the induction dose of upadacitinib for further evaluation in Substudy 2. The objective of Substudy 2 was to evaluate the efficacy and safety of upadacitinib compared to placebo in inducing clinical remission in participants. The objective of Substudy 3 was to evaluate the efficacy and safety of upadacitinib compared to placebo in achieving clinical remission in participants who had a response following induction with upadacitinib.
Aspiration pneumonia is a dreaded complication of anaesthesia because of its prevalence (1/3,886 cases in elective anaesthesia and 1/895 cases in emergency settings) and its high morbidity and mortality (3 to 9%). This chemical and/or infectious pneumonia is secondary to passage of the gastric contents into the unprotected upper airways during general anaesthesia. The prognosis depends on three factors: the presence of food debris, and the acidity and volume of the gastric contents. To prevent this complication, the French society of anaesthesia and intensive care recommends preoperative fasting rules and, in patients presenting risk factors for aspiration, the use of antacids and rapid sequence intubation. This preventive strategy is associated with certain adverse events: deferred operative procedures, discomfort and hypoglycaemia secondary to fasting, more frequent anaphylactic complications, and memory of anaesthetic induction. Over recent years, ultrasound has become more widely used by anaesthetists for local anaesthesia, vascular catheterization, haemodynamic monitoring and, more recently, 2D ultrasound estimation of intragastric volume. However, 2D ultrasound estimation of intragastric volume presents several limitations: because of the complex shape of the stomach, this technique requires a long learning curve and the measured volume is poorly correlated with reference techniques (MRI and 99Tc scintigraphy). Two studies have recently measured intragastric volume by three dimensional ultrasound with promising results.
