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 aims of the current study are as follows: i) Investigate the relationships between indices derived from ultrafast ultrasound imaging and Pditw, ii) Investigate the relationships between indices derived from ultrafast ultrasound imaging and diaphragm EMG, iii) Investigate the performance of ultrafast ultrasound for the diagnosis of diaphragm dysfunction, iv) Investigate the ability of ultrafast ultrasound imaging to decipher the cause of diaphragm dysfunction i.e. contractility alteration and/or phrenic nerves conduction defect.
The aim of this study is to understand how audiometric, cognitive and electrophysiological results relate to sentence recognition score in adults using currently a Nucleus cochlear implant.
Treatment of intrahepatic cholangiocarcinoma (ICC) remains difficult. Many patients have unresectable tumors, and survival after resection was only slightly improved with the use of adjuvant capecitabine. One of the major prognostic factors is the resection margin, patients with invaded (R1) or narrow (<5mm) margins having a higher risk of recurrence. Selective Internal Radiation Therapy (SIRT) with Yttrium-90 microspheres (also known as SIRT) is an interesting treatment in unresectable ICC. In a phase 2 study, the investigators showed a response rate of 39% and a disease control rate of 98%. Interestingly, 9 of the 41 patients were able to see their tumors downstages to surgery. It was also recently suggested in a retrospective study that patients resected after SIRT had a better prognosis than patients that could be operated upfront, despite less favorable initial tumor characteristics. Given the absence of validated neoadjuvant treatment, the promising activity of SIRT and chemotherapy combination in the unresectable setting, and the prognostic significance of close surgical margins, the aim of this trial is therefore to study this combination treatment in the neoadjuvant setting of resectable ICC.
This study aims at assessing whether electric cardioversion can act as a discriminant factor between patients requiring Pulmonary Vein Isolation (PVI) procedure alone or PVI procedure combined with substrate modulation. All included patients will undergo an electric cardioversion, then: - Patients with electric cardioversion success will be treated as per Standard of Care and according to ESC recommendations (2020). A prospective registry will be implemented for these patients. - Patients with electric cardioversion failure will be randomized in the study between 2 ablative procedures: - PVI procedure alone - PVI procedure combined with substrate modulation
The glycocalyx is a fibrillary lining structure that covers the inner surface of blood vessels. Composed of glycoproteins and polysaccharides, it is an essential determinant of vascular endothelial physiology: it limits coagulation activation and adapts capillary perfusion. Studies have shown glycocalyx alteration in various vascular and autoimmune pathologies such as diabetes, high blood pressure, chronic renal failure, ischemic heart disease, stroke, dementia, septic shock, and several other inflammatory pathologies with a common basis in vascular insufficiency. Glaucoma is a progressive, chronic and asymptomatic optic neuropathy characterized by visual field damage and abnormalities of the optic nerve head. Two hypotheses have been proposed as a basis for this progressive damage: - the mechanical theory, which explains the papillary excavation by a compression of the optic nerve head under the effect of high intraocular pressure; and - the ischemic theory, explained by a circulatory insufficiency at the level of the blood capillaries of the retina and especially of the optic nerve head. This latter theory is related to several pathologies that have circulatory insufficiency as common underlying pathophysiology, and in which damage to the glycocalyx has been well studied. Glycocalyx damage has rarely been studied in glaucoma. Yang et al. showed that the glycocalyx, present in Schlem's canal, plays a major role in the transduction of shear stress and regulation of outflow resistance to the aqueous humor, which may constitute an interesting biomarker for glaucomatous pathologies.
The role of hamstring has been studied in anterior cruciate ligament (ACL) injury prevention, mainly to counteract the anterior tibial translation , especially when contracting eccentrically, but also with passive stiffness. However, little is known about the passive hamstring stiffness after ACL reconstruction (ACLR). The primary objective of this study is to evaluate the passive stiffness of hamstring muscles after ACLR by using an isokinetic device. Secondary, we aimed to test the individual and surgical characteristics associated with hamstring stiffness and the impact of hamstring stiffness on RTS and knee re-injury. The hypotheses are that hamstring stiffness will be lower in the ACLR leg compared to the uninjured leg and to healthy individuals. Also, we hypothesized that hamstring stiffness will be lower after hamstring autograft compared to patellar tendon autograft and will increase progressively after ACLR to be symmetrical at the time for RTS. Also, we hypothesized that hamstring stiffness could be associated with better outcomes at RTS (RTS at same level and lower re-injury rates)
Intra-abdominal candidiasis remains the first origin of invasive candidiasis in critically ill patients with a mortality up to 60%. This high mortality is partly related to delay of anti-fungal treatment administration. According to experts in the field, new diagnostic methods to rapidly detect Candida in intra-abdominal infections is mandatory because the current strategies suffer from a lack of both sensitivity and specificity. The calscreener (SYMCEL®) is a new diagnostic tool to rapidly identify the presence of pathogens in biological samples based on micrometabolic activity detection. This technology also allows to measure the metabolic activity of pathogens. The ICCA project will test the feasibility, the accuracy and the diagnostic performance of the calscreener on an existing biological collection of peritoneal fluid. This collection came from a cohort of critically ill patients with intra-abdominal infection which required abdominal surgery. Intra-abdominal infections consist of bacterial peritonitis and intra-abdominal candidiasis. The presence of pathogens (bacteria and yeast) is already known, the peritoneal fluid being stored after routine analysis (bacteriology / mycology). In addition to the detection / identification of yeast will be investigated in this project, the cal screener will be used to evaluate the metabolic profile of Candida albicans in the peritoneal fluid, alone and with bacteria. This objective aims to evaluate the virulence of Candida in the peritoneal fluid from a metabolic perspective. The results will be compared to phenotypic and molecular evaluation.
A long-term venous access is frequently required in patient management. Currently, it is ensured by using the long peripheral intravenous catheters (Midline) or peripheral inserted central catheters (PICC line). Either is inserted into a peripheral vein of the upper arm and extends to the distal axillary vein. If the indications for the two catheters can sometimes be debated, the Midline catheter seems to be more and more used. The complications related to the use of PICC lines have been well described in literature, whereas the comparison of the two catheter-related complications has been less analysed. The aim of this study is to compare the incidences of catheter-related bloodstream infections linked to PICCs and Midlines.
BK virus (BKV) infection has a major negative impact on transplant recipients. No BKV-specific antiviral therapy is available, so there is an urgent need to develop new anti-BKV preventive and therapeutic strategies.
Background Transcatheter pulmonary valve implantation (TPVI) is indicated to treat right ventricular outflow tract dysfunction in patients with congenital heart diseases. Long-term outcomes following this procedure using the new generation SAPIEN 3 valve is little known. Purpose This study aims to report mid-term outcomes in a large cohort of patients who had TPVI using the SAPIEN 3 valve. Methods We designed a retrospective multicentre observational registry of patients undergoing TPVI with the SAPIEN 3 valve across centres in Europe, Middle-east and Canada. Patient-related, procedural, and mid-term outcomes data will be characterized.
