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 aim of this study is to assess whether changes in the plethysmography variability index, during a tidal volume challenge, can reliably detect simultaneous changes in arterial blood pressure pulsatility, in patients hospitalized in intensive care unit. If results will be positive, this will allow the test to be performed even in the absence of an invasive arterial catheter.
The prevalence of erectile dysfunction (ED) is about 10% in the general population, but increases with age, ranging from 9.1% in men 40-49 years to 55% in men >70. The major risk factors for ED are as follows: diabetes; heart conditions; tobacco use; obesity; injuries to the nerves that control erection; medications such as antidepressants; psychological conditions such as stress, anxiety, or depression; and drug or alcohol use (4). The International Index of Erectile Function (IIEF5) is a simple and well-validated tool for the evaluation of ED (5) and is considered the gold standard for the diagnosis and evaluation of symptom severity. The link between cirrhosis and ED has been suggested in a recent study, showing ED was also impacted by liver failure, portal hypertension and other known risk factors. In the investigators team, they showed, additionally, that neurocognitive impairment is associated with ED in cirrhosis (data not published). The prevalence of ED after liver transplantation (LT) varies among series, ranging from 66 to 86%. After LT, on the one hand, improvement of liver function and bioavailable testosterone favours the improvement of ED. On the other hand, immunosuppressive agents are suspected to worsen it. ED's reversibility has also been discussed; nevertheless, data are scarce and heterogeneous. In the investigators group, they can perform in routine a neurocognitive evaluation of patients with cirrhosis thanks to a neuropsychologist experienced in cognitive disorders occurring in patients with cirrhosis. The aims of this study are: 1) to compare the prevalence of erectile dysfunction (ED) in a population of patients with cirrhosis before liver transplantation (LT) and one year after LT; (2) to describe factors associated with ED before and after LT, with a special focus of hormonal profile, neurocognitive impairment, multimodal brain Magnetic resonance imaging (MRI) and of the type of immunosuppressive therapy used; (3) to assess the impact of ED on sexual partner; (4) to evaluate the efficacy of the treatment with phosphodiesterase-5 inhibitors (PDE-5) drugs after LT. Methods: neurocognitive tests will be performed by an expert neuropsychologist. Biological evaluation will include an evaluation of liver function, hormonal assessment (bioavailable testosterone). MRI acquisition protocol will include anatomical sequences (3D-T1, FLAIR, T2, T2 *), diffusion tensor imaging (DTI) and two single voxel MR spectroscopy acquisitions. Evaluation will be performed before LT and 1 year after LT.
The objective of this study is to evaluate the immune profile of plasma cells and immune effector cells in paired peripheral whole blood and bone marrow samples from MM patients by standardized flow cytometry. The quantitative and/or qualitative variation of these immune effectors according to the different status of myeloma pathology (diagnosis, relapse or refractory). It is interesting to assess the extent to which a particular immune profile is associated with a better therapeutic response for a given treatment. In addition, the study will validate the stability of the samples between T0 (< 4 hours after sampling) and T0 + 72 hours.
Patient preference and experience can impact patients' adherence and persistence regarding a treatment, especially when switching. A number of factors contribute to this, including their beliefs, fears, expectations, and overall knowledge. This is compounded by the fact that many switched patients are not trained on how to use the new injection device. Specifically, some patients report a degraded experience with current adalimumab biosimilars (40mg/0.8mL) as compared to the originator: injections appear more painful and seem to cause more bruising. Indeed, treatment-related factors such as treatment volume or the presence of citrate have the potential to negatively impact patient experience and contribute to local reactions at or around the injection site, such as pain and swelling. Yuflyma® (CT-P17 adalimumab), developed by Celltrion Inc., is a biosimilar of the anti-TNF treatment adalimumab, having obtained a marketing authorisation from the European Commission on 11th February 2021 (addressed to Celltrion Healthcare). Yuflyma® is the first high-concentration adalimumab biosimilar (40mg/0.4mL) available in France, which makes the product similar to the currently available adalimumab originator formula in terms of drug concentration. Studying patient experience over the course of a switch involves querying patients at the time of prescription, while they are still under the previous treatment, and for the following 3 months, during which they have been able to pick up their prescribed medication from a pharmacy and have started using the new treatment. Describing patient experience over the course of a switch from another adalimumab (originator or biosimilar) to Yuflyma® would contribute to identifying significant factors which contribute to patient experience and satisfaction. Our primary objective is to assess patients' overall satisfaction with the injection after the switch to the high-concentration adalimumab biosimilar Yuflyma®, at 3 months following the initiation, compared to their experience with the previous adalimumab. - Overall satisfaction with the injection (7-level likert) before initiation - Overall satisfaction with the injection (7-level likert) 3 months after initiation
Pilot, prospective, monocentric study aimed at evaluating the rate of patients with circulating "cancer cell/macrophage" hybrid cells in the peripheral blood and the evolution of this rate over time. The study will be conducted on a population of patients with leiomyosarcoma and treated in the context of routine care. 20 patients will be included: - 10 patients with localized disease. - 10 patients with metastatic disease. For each included patient, blood samples will be collected during baseline visit and up to 24 months after inclusion.
Alzheimer's disease (AD) has gradually become one of the major global public health issues due to its prevalence, which increases with age and life expectancy, and the economic cost of caring for patients whose cognitive decline progressively leads to loss of functional autonomy. The diagnosis of AD is based on a multidisciplinary approach, involving, among other things, evaluation of the medical history together with clinical symptoms and signs, neuropsychological tests and neuroimaging. The quantification of cerebrospinal fluid (CSF) core biomarkers (amyloid beta peptides [Ab1-40 and Ab1-42], total tau [t-tau] and its phosphorylated form on threonine 181 [p-tau(181)]) has progressively proven utility for the diagnosis of AD and its prodromal forms. CSF biomarkers are now included in international guidelines for the diagnosis of AD in research settings and clinical practice and the Alzheimer's Association appropriate use criteria for the use of lumbar puncture and CSF testing in the diagnosis of AD have been published. Such biochemical diagnostics are currently implemented in many specialized centers around the world. Recent progress in the biological diagnosis of AD is considerable, with the possibility, thanks to ultra-sensitive tests realized notably with the SIMOA technology, of having Ab1-40, Ab1-42, t-tau and p-tau(181) also detectable in the blood using commercial kits. The performance for AD detection has been evaluated by many groups including on retrospective samples. It is now essential to evaluate the interest of blood-based biomarkers of AD, prospectively and in real life condition to confront them with pre-analytical and analytical variabilities. It is also important to position them in relation to CSF analysis and AD management, from risk assessment, diagnosis, to therapeutic strategies.
In patients with persistent AF (PsAF), ablation limited to pulmonary vein (PV) isolation is the most straightforward approach, but results only in 50% of arrhythmia freedom at 1 year follow-up. Substrate modification strategies have failed to demonstrate their superiority with variable reported success rate. The Marshall network is a highly arrhythmogenic structure that has not been systematically targeted so far, probably because of the absence of dedicated tools to make its ablation simple and easy. We sought to investigate the use of a specific catheter for visualization and ethanolization of vein of Marshall allowing to systematically include this target in the ablation set. The main objective of this study is to demonstrate the feasibility to use the Targeted Endovascular Delivery (TED) catheter specifically for visualization and ethanolization of vein of Marshall.
An Open-label Extension Study to Evaluate Long-term Efficacy and Safety of Odevixibat (A4250) in Children with Biliary Atresia
The dual isotope method has been recently developed and used to evaluate indispensable amino acid (IAA) digestibility of various protein food such as legumes, eggs and chicken meat in healthy adults and children. The dual isotope method is an indirect method based on the measurement in plasma of absorbed IAA from a deuterium (2H) intrinsically labeled test protein compared against the same IAA of a carbon 13 (13C) intrinsically labeled standard protein of known digestibility or crystalline amino acids (AA) of theoretical 100% digestibility. However, digestibility data estimated with the dual isotope method have not been directly compared with ileal IAA digestibility directly determined through ileal digesta sampling. The goal of this study is to assess the IAA digestibility of intrinsically 2H-hen's egg in healthy volunteers using both indirect and direct methods.
