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.
This study will investigate the efficacy and safety of "deep" rTMS on neuropathic pain or fibromyalgia. It will be randomized and sham controlled and will last 3 months. Patients will be randomized to receive acctive rTMS or sham rTMS and will receive repeated rTMS sessions (5 daily sessions then one session per week then every 2 to 3 weeks for up to 10 weeks).
This study focuses on a population of adult patients placed under peripheral Veno-Arterial Extracorporeal Membrane Oxygenation (VA-ECMO) for refractory cardiogenic shock. Cardiogenic shock, primarily caused by myocardial infarction, is associated with a high mortality rate that remains around 50%, despite advancements in the field of coronary reperfusion. VA-ECMO is a rapidly growing cardiac support technique worldwide. Its goal is to improve peripheral organ perfusion even as myocardial damage continues, thereby enhancing the prognosis of patients with severe multiorgan failure. VA-ECMO is a temporary cardio-respiratory support technique based on the principle of extracorporeal circulation. However, patients under VA-ECMO are at risk of experiencing various complications, including infectious, thromboembolic, hemorrhagic complications, or malfunctions of the ECMO machine itself, with the incidence increasing with the duration of assistance. Numerous authors and scientific reviews highlight the increased risk of Acute Pulmonary Edema (APE) in patients under peripheral VA-ECMO, attributing it to the elevation of afterload induced by retrograde arterial reinfusion against the residual native blood flow, hypothetically leading to an increase in Pulmonary Artery Occlusion Pressure (PAOP). This phenomenon is presumed to intensify as the VA-ECMO reinfusion rate increases. Furthermore, APE under ECMO-VA represents a turning point in the patient's course. Brechot et al. demonstrated that patients who developed APE under VA-ECMO had a prolonged ECMO duration, a higher reliance on mechanical ventilation, an extended stay in critical care, and a higher mortality rate compared to patients who had previously undergone a left ventricular unloading technique (aimed at reducing PAOP and the risk of APE). However, until now, no physiological study has assessed the specific effect of the variation in peripheral VA-ECMO flow on the change in PAOP during a dedicated protocol. It is with the aim of addressing this question that the investigators are considering the PAPO-Flow study.
Cardiopulmonary bypass (CPB) surgery present risk of acute postoperative neurological complications. These complications are most often postoperative cognitive dysfunction (confusion, cognitive disorders, executive disorders) with a prevalence of up to 40% at 5 years, and ischemic (stroke) with an incidence of between 0.4 and 14%. The causes are usually multifactorial, but altered cerebral perfusion during CPB surgery is an important prognostic factor. Data regarding the effect of deep hypothermia on cerebral perfusion during CPB in adult are scarce. Currently, aortic arch replacement following aortic dissection or aneurysm, and pulmonary artery endarterectomy (PAE) in the treatment of pulmonary hypertension of post embolic origin are performed under deep hypothermia. In this latter indication, the need to obtain a completely bloodless operating field necessitates complete circulatory arrest during short period of time to enable the surgeon to optimally remove the clot materials located into the pulmonary arteries. To protect the brain and avoid irreversible brain injury during circulatory arrest(s), body temperature is lowered at 18-20°C. Deep hypothermia can lead to significant arterial vasoconstriction, which can reduce the blood supply to the brai. It also increases the solubility of CO2 in the blood, leading to respiratory alkalosis, which can also lead to vasoconstriction of cerebral vessels, increasing the risk of ischemic lesions. In adult there is no consistent data on the cerebral perfusion during PAE surgery under deep hypothermia at 18-20°C. Animal studies showed that cerebral regulation seems to be preserved under these conditions. A better understanding of the effect of deep hypothermia on cerebral perfusion during PAE surgery is essential to adapt our management to limit the occurrence of postoperative neurological complications.
Ambispective post-market data collection on visual symptoms, patient satisfaction and surgeon experience with the TECNIS PC IOL.
The goal of this randomised controlled, cross-over clinical trial is to compare High Flow Nasal Cannulas (HFNC) and Continuous Positive Airways Pressure (CPAP) in neonates over 34 weeks' amenorrhoea (SA) up to children weighing less than 20 kg with respiratory failure. The main question it aims to answer is the non-inferiority of high flows of high-flow nasal cannula compared with CPAP by analysis of diaphragmatic contraction (EAdi (Electrical activity of diaphragm)). Participants with respiratory failure and need of non invasive ventilation and nasogastric tube will receive 4 different increasing flows of HFNC and Positive End-Expiratory Pressure of 7 cmH2O with CPAP during 30 minutes for each flow rate and CPAP. The electrical activity of diaphragm and clinical data of the patient upon each flow and support will be collected. According to the cross-over procedure, the patients will change groups (increasing flows of HFNC or CPAP) in order to perform the remaining analysis.
The purpose of this study is to assess the safety, tolerability, drug levels, drug effects, and impact on disease severity of BMS-986326 in participants with moderate-to-severe atopic dermatitis (AD).
Acute liver failure in cirrhotic patients is associated with a one-month mortality of 48%. Encephalopathy, largely related to hyperammonemia, is a frequent complication of liver failure and is a poor prognostic marker. Lactulose decreases ammonia by acidification of the colon, replacement of urease-producing bacteria and creation of a laxative effect. Thus, the administration of lactulose in patients with severe hepatic encephalopathy reduces mortality by more than 40%. In intensive care patients, lactulose is often administered rectally. The use of simple rectal tubes is associated with frequent leakage of lactulose as well as faecal discharge and therefore risks of infection and skin lesions. Balloon rectal tubes with a drug delivery valve have recently been developed and used in this indication. The aim of this study is therefore to describe the use of these balloon rectal tubes to administer Lactulose in severe hepatic encephalopathy. This suggests that ammonia reduction in these patients may prolong survival time. No studies have described the administration of Lactulose via the rectal route with a balloon tube. The descriptive methodology is therefore appropriate. This is a preliminary study allowing data collection to establish the methodology for a subsequent clinical trial.
The goal of this prospective, interventional study is to evaluate the mechanisms of acquired resistance to amivantamab monotherapy in patients with advanced NSCLC with EGFR ins20. The main question it aims to answer is: What are the mechanisms of acquired resistance to amivantamab monotherapy in this population of patients ? How anticipate the efficacy of subsequent systemic therapies ? After this information session, the participant will be asked to sign the study informed consent. A blood samples (2*10 mL on ethylenediaminetetraacetic acid (EDTA)) will be taken at time of disease progression and will be sent for central liquid biopsy ctDNA analysis. If available, tumor tissue will also be sent for DNA NGS analysis.
Graft versus Host Disease (GVHD) is frequent after allogeneic stem cell transplantation (alloSCT). GVHD occurs following 2 patterns : acute GVHD (aGVHD) or chronic GVHD (cGVHD). The latter occurs in nearly 50% of patients and its pathogenesis remains poorly understood. Previous translational studies have delineated biological immune dysregulation involved in cGVHD and facilitated the development of new drug and therapeutic strategies. New aspects of T and B cells collaboration in the context of cGVHD using blood description of a key player called TFH, classicaly involved in germinal center reaction, were previously uncovered (Forcade et al, Blood 2016). Previous studies in the context of auto-immune inflammation (lupus nephritis) or organ transplant rejection, suggested that target tissue could contain accessory lymphoid structures (TLS). The description of such structures in cGVHD target tissue would give the opportunity to directly analyze immune key player involved the pathogenesis of cGVHD.
