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 goal of this clinical trial is to compare two guiding catheters in patients with coronary artery disease during a percutaneous coronary intervention between Guidex® Guiding catheter (DEMAX) and Launcher™ coronary guide catheters (Medtronic). The main question[s] it aims to answer are: - Aren't the safety of medical devices inferior to each other? - Aren't the efficacyof medical devices inferior to each other? Participants will be randomized (1:1) and have a percutaneous coronary interventionwith one of the two guiding catheters.
Currently, measurement of transdiaphragmatic pressure (Pdi) using oesophageal and gastric balloons is the gold standard for the assessment of diaphragmatic effort. This technique is relatively invasive and its interpretation may be complex. The diaphragmatic longitudinal strain (LSdi) and strain rate (LSRdi) might provide additional information in the assessment of diaphragmatic effort and movement during SBT, allowing early detection of diaphragmatic dysfunction. Patients will be monitored during a 30-120 minutes SBT consisting of no assistance on the ventilator using CPAP with a pressure level of 0 cmH2O. Parameters to evaluate diaphragm function will include diaphragmatic strain (LSdi and LSRdi), diaphragmatic thickening fraction (TFdi), and airway occlusion pressure (ΔP0.1 and ΔPocc). These parameters will be measured immediately before ('baseline') the SBT, as well as 2 minutes ('early' assessment), 15 ('intermediate' assessment) and 30 minutes ('late' assessment) after the beginning of the SBT.
The main objective of this study is to demonstrate that 15 transcranial direct current stimulation (tDCS) sessions of 30 minutes at 2 mA intensity are effective to reduce suicidal ideation
This project will explore the involvement of the serotonin system in the pathophysiology of PD-related central pain. Thus, the serotonin system will be evaluated in PD patients with and without central pain who will benefit from brain positron emission tomography (PET) allowing in vivo imaging of 5HT1A receptors and multimodal brain MRI including morphometric imaging and functional connectivity (resting state acquisition).
The hypothesis is that Nasal High Flow therapy for patients with Hypercapnic Acute Respiratory Failure without acidosis, in addition to standard treatment would improve the care.
Evaluation of the safety and performance of the Navitor TAVI System in a Global Study
When performing coronary angiography in a stable situation, the identification of an intermediate coronary lesion (between 50 and 70%) is common, and requires additional functional evaluation. The gold standard for this evaluation is Fractional Flow Reserve (FFR). FFR is a flow ratio transformed into a pressure ratio by simplification, neglecting some parameters, especially microcirculatory resistance. The aim of this study is to investigate hemodynamic and structural assessment induced in specific conditions, and their repercussion on functional assessment by FFR to implement the diagnostic approach and personalize it for each patient.
Therapeutic advances in oncology have transformed the prognosis of cancer patients, placing a significant number of them either in a context of recovery or in prolonged remission close to a chronic disease. Thus, the reconquest of a life after cancer becomes possible but raises many challenges for the patient, his entourage, the medical profession and our society. One of the major challenges is the detection and management of treatment side effects for all patients. In addition to the standard organic assessment (glycaemia, creatinine, liver test, blood count), we are mainly interested in muscle deconditioning and cognitive impairment, which are particularly disturbed in these populations. After the evaluation day, patients are referred to the most appropriate structures (Adapted physical activity, sports for health, and rehabilitation at Henry Gabriel Hospital). JUMP research is part of axis 2 of the 2021-2030 cancer plan: "Limiting sequelae and improving quality of life", through sheets 1 (research) / 6 (access and quality) / 7 (prevention). This leads to the concrete implementation on the territory of adapted care channels in the city: medical structure, physiotherapy, Adapted Physical Activity (APA) structures, associative structures; which makes it possible to develop and strengthen the city-hospital link. Finally, it allows the patient to take ownership and get involved in the project, allowing in the future to make them truly active in they care and to advise and motivate their peers. This non-interventional research is classified as "research involving human subjects", class 3 . The objective of this research is to evaluate the impact of cancer on the musculoskeletal system and to test ultrasound as a clinical examination for the detection of sarcopenia in this population.
Post-exposure prophylaxis (PEP) using doxycycline 200 mg within 24 hours of unprotected sexual intercourse to prevent sexually transmitted infections has demonstrated a reduction in the incidence of chlamydial and syphilis infections and syphilis infection by 70% and 73% in men who have sex with men (MSM) undergoing pre-exposure prophylaxis prophylaxis (PrEP) for HIV. Other studies are underway or in development on doxycycline prophylaxis for bacterial STIs, which are particularly common in this population. Monitoring adherence to PEP is of great interest in guaranteeing the effectiveness of this strategy and to be able to assess the uptake of PEP among PrEP users. Among the many methods for assessing adherence, measuring drug concentrations is a more accurate measure of adherence than self-reporting. The therapeutic monitoring of doxycycline and the assessment of adherence have been described using plasma and hair samples, allowing estimation of intake over the last 3-4 days and 4 months, respectively. Nevertheless, these biological matrices present several limitations for application in clinical practice: reflecting the duration of exposure should be more in line with the frequency of visits (2 months), and the collection of hair samples may be difficult due to refusal or short hair. On the other hand, interpretation of the hair assay is limited by the degradation of doxycycline in this matrix, which could lead to underestimation of drug intake. By Therefore, new biological matrices are needed for more accurate assessment of doxycycline adherence in post-exposure prevention monitoring. The objective is to evaluate the pharmacokinetics of doxycycline in plasma, whole blood, dried blood spots (DBS), urine and hair after a single dose of doxycycline in men using oral doxycycline for post-exposure prophylaxis of sexually transmitted infections (syphilis or Chlamydia trachomatis) and having sex with men.
Alternating Hemiplegia of Childhood (AHC) is a very rare neurological disorder of genetic origin, combining paroxysmal episodes and neurodevelopmental impairment. The disease is generally sporadic, and its incidence has been estimated at 1 in 100,000 births, with around 500 cases published worldwide. The true prevalence of AHC may be underestimated due to a lack of understanding of the disease and a high degree of phenotypic heterogeneity. It should be noted that, to date, it is difficult to assess the clinical characteristics of AHC patients in a homogeneous way. The lack of disease-specific clinical outcome measures therefore constitutes a critical node for advancing AHC research. In addition, recognition of the pattern of movement disorders and the ability to classify their severity are very important and useful for the clinician. Homogeneous disease assessment will help plan rehabilitative and pharmacological interventions, facilitate monitoring of treatment outcomes, and predict prognosis. This is why an AHC assessment scale have been developed in collaboration with clinical teams from the IAHCRC consortium. The scale has already been tested and validated on Italian and Spanish patients. The aim of this study is therefore to validate the use of this same scale on our French population of AHC patients. The hypothesis of the study is that the practical use of this scale specific to alternating hemiplegia is reproducible. To this end, all the items on the scale will be scored independently for each patient by 4 neuropediatricians with expertise in the disease, in order to observe the reproducibility of the results obtained with this scale. The scale will be used for twenty AHC patients of all ages.
