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.
Follow-up of patients with complex congenital heart disease (CHD) usually involves ultrasound imaging or even MRI or CT scans of the heart and stress testing. But these examinations can be challenged in terms of their sensitivity. Thus, the development of non-invasive jugular venous and radial arterial pressure sensors, reflecting the hemodynamic function of the right heart, would be very useful to the clinician responsible for early detection of a deficit in right ventricular function.
The patient is randomized to one of the following groups: - Experimental group: Radiotherapy in painting dose on histoscannographic mapping - Control group: standard pan-sinus radiotherapy
Time processing is fundamental to survival and goal reaching in humans. Different time scales (seconds, minutes, and beyond) are processed through specific cognitive processes involving different neural representations. It is generally agreed that time scale in seconds-to-minutes range named "interval timing" would be anatomically linked to the striatum. Indeed, it is possible to demonstrate a deficit of interval timing processes in patients suffering from striatal damage (Huntington's disease). However, recent findings show involvement of a second brain structure, the hippocampus, in interval timing processing in the minutes range, suggesting an interaction between the striatum and hippocampus. Presumably, patients with hippocampal damage (Alzheimer's disease) would specifically show a decrease in performance for this minutes-range time scale. This study aims to provide a better understanding of the role of the striatum in the treatment of time and its interactions with other brain structures such as the hippocampus. More specifically, it is unclear whether the striatum plays a platform role that would always be involved regardless of the time scale, as suggested by the unified model of time or whether different brain structures is solicited according to the time scale, as suggested by the modular system model. In order to elucidate these issues, a potential double dissociation between brain structures and time scales will be tested.
The PROFA study is an international, multi-centric observational and validation study to assess the patient-reported, psychosocial and economic outcomes of patients with Friedreich Ataxia (FA). Eligible patients will be recruited from six study centers in Germany, Austria and France. Patients will complete a baseline assessment via face-to-face interviews at the study centers and multiple momentary follow-up assessments via a mobile-health app at home daily to monthly for six months. Study results will gain essential and in-depth insights into the daily life of patients with FA.
Hypnosis is a technique allowing the patient to focus his mental attention on a thought or a sensation, with the aim of reducing or modulating the intensity of a negative feeling or an ordeal encountered during the course of treatment. This tool can be used when patients are faced with chronic disorders (pain, anxiety, ...) or iatrogenic effects (nausea, asthenia, ...). The patient is referred to hypnosis care by the doctor, psychologist or paramedics who follow him, when they detect a need. Several scientific studies have shown the effectiveness of hypnosis in improving the quality of life of patients with breast cancer and in reducing pain during invasive procedures. On the other hand, in hematology, no research has measured the evolution of anxiety, over time, in patients receiving hypnotherapy.
Hyponatremia is a frequent complication of subarachnoid hemorrhage (SAH) with a prevalence of 30 to 50% in patients with this condition. This hydro-electrolytic disorder is responsible for an increase in morbidity with the appearance of neurological disorders. Also, it has been shown that there are ionic changes in the cerebrospinal fluid and a probable alteration of the blood-brain barrier in patients with SAH. The kinetics and relationship between hyponatremia and these changes remain unknown. The main objective of the study is to determine whether the change in cerebrospinal fluid (CSF) composition, precedes the development of hyponatremia. For this, the investigators propose to study the evolution of the CSF ionogram with the blood ionogram. Furthermore, they will perform additional analyses on the basis of a control group (CSF of patient with normal pressure hydrocephalus) to determine the effect of SAH on ionic changes. The hypothesis of the study is that there is a correlation between the change in CSF blood ionogram and the development of hyponatremia between day 0 and day 14.
The management of locally advanced cervical cancer (Figo >IB) is based on radiochemotherapy (RCT) followed by brachytherapy. At present there is no personalized treatment, all patients undergoing radiochemotherapy will follow a conventional treatment by external radiotherapy (46 Gy in 23 sessions associated with cisplatin (CDDP) weekly) and brachytherapy to achieve a total equivalent biological dose around 80-90 Gy).The efficacy of this treatment has been proven for most patients, almost 80% being in complete response after RCT. Nevertheless, on an individual scale, there remains a significant variation in the tumor response, with patients who respond from the first week of treatment, "early responders" or, on the contrary, others who present significant tumor residues after external beam radiotherapy.Various macroscopic tumor volume (GTV) response patterns have been identified based on magnetic resonance imaging (MRI) at diagnosis and MRI before brachytherapy, implying very different clinical target volumes for brachytherapy technique. The difference in tumor volume response has been identified as having a major impact on treatment response. This is the first study attempting to evaluate tumor response in real time during radiochemotherapy treatment. Knowing the tumor response during treatment will make it possible to modify the management of locally advanced cervical cancer, several therapeutic options might then be discussed depending on the early response to treatment: dose de-escalation for early responders, reduction of time total treatment, personalization of brachytherapy management (technique and dose). This observational study will allow rapid identification of responder and non-responder patients and might be used as a basis for personalized treatment strategies
Research hypothesis - Recent studies have shown that high-dimensional descriptors of the cardiac function can be efficiently exploited to characterize targeted pathologies. In this project, the investigators hypothesize that echocardiograms possess a wealth of information that is currently under-exploited and that, combined with relevant patient data, will allow the development of robust and accurate digital tools for etiological diagnosis. Objectives - Based on key advances recently obtained in image analysis, notably by members of the consortium, the objective of this project is to develop rigorous and explainable cardiac disease prediction models from echocardiography based on the transformer paradigm (AI). The strength of this study lies in the development of a strong AI framework to model the complex interactions between high-quality image-based measurements extracted from echocardiograms and relevant patient data to automatically predict etiological diagnosis of cardiac diseases
Obesity is recognized as a major public health problem. Recent research suggests the involvement of the gut microbiota in the development of obesity. Indeed, obese people are characterized by a dysbiotic intestinal microbiota. Periodontitis are chronic inflammatory oral pathologies linked to an imbalance between the bacterial etiological factor, oral dysbiosis, and the host's immune defenses.They lead to the destruction of the supporting tissues of the tooth and an apical migration of the periodontal attachment system, thus leading to the formation of the pathognomonic entity of the disease, the periodontal pocket.the presence of bacteria of oral origin such as Porphyromonas gingivalis (Pg) has been demonstrated in the adipose tissue of obese patients inducing a chronic low-grade inflammatory response by macrophages which leads to the proliferation of adipocyte precursors predisposing to obesity. The main objective is to assess the average amount of Porphyromonas gingivalis (Pg) in the saliva of obese people (BMI ≥ 30) with periodontitis.
This is a prospective, randomized, double-blind, parallel-group controlled trial. The aim of this research project is to compare the clinical benefits achieved in patients with Borderline Personality Disorder (BPD) following two types of intervention: ccPAS active or ccPAS sham.
