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.
Intra-hospital transport is a frequent procedure in the ICU, involving patients with the highest severity scores. Although some studies estimate the rate of adverse events to be around 33% during intra-hospital transport, including 4% of serious adverse events, the epidemiological data available is small, heterogeneous, and probably subject to methodological bias. The aim of this study observational prospective observatoinal study is to determine: - the different practices existing between ICUs ("practice survey") - the occurrence of adverse events during intra-hospital transport provided by intensive care units (epidemiological study)
Primary Sjögren syndrome (pSS) is a systemic autoimmune disease that mainly affects the exocrine glands leading to severe dryness of mucosal surfaces, principally in the mouth and eyes. The other clinical manifestations are fatigue and musculoskeletal pain. Diagnosis of pSS associates clinical abnormalities with specific antibodies (Ro/SSA and La/SSB antibodies) or histopathological criteria of a minor salivary gland biopsy (the presence and number of lymphocytic focus, as well as chronicity findings like acinar atrophy, ductal dilatation or fibrosis). Apart from its variable sensitivity, one of the weaknesses of minor salivary gland biopsy is the delay in obtaining the result due to the time required to prepare the sample for histological analysis. Our group recently demonstrated the use of full-field optical coherence tomography (FF-OCT) to visualize structural changes associated with the inflammatory processes in Giant Cell Arteritis (temporal artery biopsy examination). It may suggests a further use of dynamic FF-OCT of minor salivary gland biopsy to visualize structural changes associated with the lymhocytic focus to ensure rapid on-site diagnosis of pSS.
Voice recordings taken prior to the start of repetitive transcranial magnetic stimulation (rTMS) therapy will be used to develop a predictive model of treatment response using machine learning for patients with major depressive disorders (MDD).
Changes in heart rate variability following a single session of rTMS will be tested as a predictor of response to a course of 30 rTMS sessions in patients with major depressive disorder (MDD).
Lichen planus (LP) is a chronic inflammatory disease of unknown aetiology, affecting the skin and mucous membranes, characterised by a CD8+ cytotoxic T-cell infiltrate, associated with epithelial cell death and disruption of the basement membrane zone. In previous work, T cell antigen receptor (TCR) repertoire studies were performed. In all patients tested, whether with erosive or non-erosive LP, unique nucleotide sequences, called clonotypes, have been identified. They appear during the process of TCR gene rearrangement. These clonotypes are specific for human papillomavirus (HPV) in blood and lesions, suggesting antigenic stimulation of these clonotypes by a viral epitope of HPV, which crosses with an epitope on keratinocytes. The diagnosis of LP is made on the basis of clinical and histological criteria, but in some patients and in some anatomical locations, the diagnosis is difficult to make and LP may be confused with other skin conditions.
The aim is to improve the diagnosis of chronic lower limb venous thrombosis before a lower limb venous recanalization procedure. Additionally, if the MRI scores are comparable to those of the CT, MRI would reduce radiation exposure and limit the need for foot vein punctures that accompany CT use.
The team hypothesizes that fully automatic analysis of AAA could provide increased performance (decreased duration of segmentation with increased reproducibility and decreased inter and intraobserver variability) to detect aortic aneurysmal sac enlargement (volumes and diameters) and predict the risk of complications during the procedure and during follow-up (MAE, MACE, MALE, Stroke) compared to standard methods of measurement relying on approximate maximum sac diameter.
"Weaning from mechanical ventilation is a crucial step in the intensive care unit. Several factors complicate weaning and increase the risk of failure. To predict the success of extubation, the spontaneous ventilation test (T-Tube) remains essential. Despite this, the failure rate is around 10-20%. Failed extubation is not without consequences, since it increases the risk of pneumopathy and mortality. It therefore seems essential to identify potential extubation failures using effective predictive criteria. Several of these predictive criteria have been studied separately in the literature, but are still not widely used in practice. Many studies have sought to identify these predictive criteria, without actually linking them. However, when combined in a single assessment prior to extubation, they could represent a reliable prediction and decision-making aid. In the intensive care unit at Hôpital Bichat Claude Bernard, a team of physiotherapists dedicated solely to this unit carries out a routine EPIC Assessment, combining several criteria, some of which have individually demonstrated their reliability in predicting extubation outcome. Physiotherapists are health professionals working as part of the intensive care team, and are well versed in issues relating to bronchial congestion, respiratory function and muscle strength, whether for breathing or locomotion. Similarly, their involvement in issues relating to swallowing disorders acquired in intensive care gives them an overall view of the patient's ability to protect his or her airway post-extubation. The EPIC Assessment has been designed by them to address these issues. With the help of this assessment, and by following the cut-offs of the various criteria, they link the different criteria making up the EPIC Assessment and communicate a ""favorable"" or ""unfavorable"" opinion for extubation. Our hypothesis is that the EPIC Assessment is, in addition to its interpretation by physiotherapists, a reliable tool for predicting the outcome of extubation."
Primary hyperparathyroidism has been associated with an impaired quality of life. Surgery has been suggested to improve this outcome in patients with baseline quality of life impairment; however, few studies have used specific tool for quality of life assessment this pathology, none being validated in French version. The aim of this study is to validate the parathyroid assessment of symptoms (PAS) questionnaire in French language to evaluate quality of life impairment and the impact of surgery in patients with primary hyperparathyroidism.
Squamous cell carcinoma (SCC) could be a very aggressive cancer and has a bad prognosis if not detected early and thus is associated with high mortality. The development of simple and reliable biomarkers for the early detection of SCC is one of the solutions to better diagnose, treat these tumors, evaluate and monitor treatments, and hence reduce mortality. In a previous work, the investigators demonstrated the ability of Proton Magnetic resonance spectroscopy (1H-MRS) to non-invasively assess spectroscopic and metabolic profiles of tongue tissue in healthy subjects. In the present work, the investigators challenge the use of in-vivo 1H-MRS as a potential method for non-invasive metabolic monitoring of patients with squamous cell carcinoma of the tongue undergoing therapy. Thus the main objective is to study the spectroscopic and metabolic differences, e.g. including variation in the metabolite TMA-Cho (trimethylamine-choline), of tongue tissue between healthy subjects and in patients with squamous cell carcinoma of the tongue, before and after surgery.
