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.
Thrombo-embolic venous diseases are represented by deep venous thrombosis and/or pulmonary embolism. In some patients with repeated thrombosis or occurrence of thrombosis in unusual sites, the etiological workup remains negative, which represents a problem for the management of the anticoagulant treatments. Recently, two factors have been identified as important in the physiopathology of hemostasis and coagulation: the presence of clonal hematopoiesis of indetermined potential (CHIP) and the formation of neutrophil extracellular traps (NETs). In this study, these two factors will be studied in patients with repeated venous thrombosis or thrombosis occurring in unusual site.
Reality-monitoring characterizes the ability to determine whether information was perceived in the environment or only imagined . Impaired reality-monitoring abilities have been associated with hallucinations in patients with schizophrenia and patients with Parkinson's disease. The investigators hypothesize a link between dopaminergic (DA) transmission and reality-monitoring.
The aim of the study is to assess the correlation between orthodontic treatment and temporomandibular joint (TMJ). For that, an evaluation with a virtual articulator (Modjaw) is carried out before and after the treatment. The condylar course are compared. Furthermore, the eventual TMJ symptoms are also compared before and after.
Medico-Economic Randomized Trial comparing Focal HIFU Treatment to Radical Prostatectomy in Patients with Favorable Intermediate Risk Prostate Cancer
In this prospective, post-market, multi-site, open-label, crossover trial, women with urinary incontinence requiring the use of diapers (changes complets (French term)) at night will be 1:1 randomized to a treatment sequence using two devices (PureWick™ System and Hollister® Female Urinary Pouch External Collection Device) and followed for approximately 10 weeks through 2 treatment phases. The primary objectives are to evaluate safety (skin injury) and efficacy (capture rate). Safety will be assessed using the Draize Scale and efficacy will be measured based on daily urine capture rate.
As the occurrence of thrombosis in post surgery is rare, it seemed difficult to study only this one. This is why we decided to test the bioimpedance, temperature and green, red and infrared light absorption measurements of the prototype during the weaning of the flap during surgery. Indeed, during weaning the investigators voluntarily interrupt the arterial and venous flow to transfer the flap to the breast. This weaning corresponds to a thrombosis model. The patients will benefit from an "improved" postoperative monitoring. Indeed, in addition to the classical clinical monitoring, they will benefit from an additional monitoring during 5 days thanks to the realization of an ultrasound of the flap which will be carried out every 6 hours the first 24 hours then every 12 hours. This protocol is therefore a feasibility study for the collection of data of interest.
Sixty percent of newly diagnosed head and neck squamous cell carcinomas (HNSCCs) are at a locally advanced (LA) stage. Depending on tumor site, stage, and resectability, locoregional failure rates can range from 35% to 65%. The persistence of residual disease at the end of treatment is a major prognostic element but is not always reliably assessed by current imaging techniques. Up to 40-50% of patients have residual adenomegaly and only 30% have viable disease when further adenectomy is performed. Sensitive and reproducible detection of residual disease after treatment is a major challenge in this patient category. 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography-computed tomography (PET/CT) guided surveillance, with a negative predictive value of 95-97%, has proven to be non-inferior to cervical curage in HNSCCs with residual adenomegaly. Cervical curage is now indicated only if the response assessed by PET-CT is incomplete. Nevertheless, the ability of PET-CT to predict treatment failure is unsatisfactory due to a high frequency of false positives, because of inflammatory changes, with a positive predictive value of about 20-50%. Circulating tumor DNA (ctDNA) may provide a more reliable assessment of response to potentiated radiotherapy. Liquid biopsy monitoring of response in patients treated with potentiated radiation therapy for locally advanced HNSCCs a has been shown to be feasible. In 85% of patients, ctDNA is detectable and correlates significantly with tumor volume and response to treatment. In addition, one study showed that post-radiotherapy analysis of circulating HPV16 viral DNA (cvDNA) in patients with HPV16-related HNSCCs complemented PET-CT and helped guide management decisions. HPV16 cvDNA and PET-CT have similar negative predictive values, whereas the positive predictive value is higher for HPV16 cvDNA (100% versus 50%). Nevertheless, current data are insufficient to allow routine use of this marker. This is a multicenter, single arm, open study for patients with a locally advanced head and neck cancer for which a potentiated radiotherapy is indicated.
The assessment of digestive inflammation and disease activity in paediatrics Crohn's disease (CD) is currently based on anamnestic, clinical and paraclinical elements such as the paediatric CD activity index (wPCDAI) , faecal calprotectin measuring or digestive endoscopy. Infrared thermal imaging is based on capturing electromagnetic waves, on a specific Wavelength, emitted by the human body surface and representing local thermic-metabolic activity. It concern metabolic activity in digestive inflammations. Infrared imaging is a non-invasive, contactless, stressless technique that assess the variations in skin surface temperature of the patient's entire abdomen or more targeted areas in a single photography. This technique would be useful for determination of Crohn's disease activity, inflammation's degree and partial mapping of inflammatory lesions. In a specific room with a patient lying, the investigators will determine the abdominal infrared radiation with a FLIR® thermal camera. This will be correlated with the measurement of the faecal calprotectin concentration and the composite CD activity index wPCDAI. All measurements will be performed during the standard follow-up of Crohn disease. No additional follow will be necessary.
In patients with severe obesity, bariatric surgery provides consistent and long-term weight loss. BMI ≥50kg / m2 is an independent factor of increased morbidity / mortality in bariatric surgery compared with patients weighing less than 50 kg / m2 (1.2% and 0.8%) mainly due to technical difficulties. Preoperative weight loss reduces this morbidity / mortality. Recent studies have shown that blocking blood vessels to a particular portion of the stomach (bariatric or left gastric artery embolization) can temporarily decrease levels of the appetite inducing hormone ghrelin, and result in weight loss. The purpose of this study was to evaluate the safety and effectiveness of the association bariatric embolization before sleeve gastrectomy in super obese patients.
