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.
One-tenth of the population suffers from insomnia, increasing their risk on other health problems such as depression. Self-reported sleep quality only was historically leading for insomnia diagnosis, but more recently a state of 24-hour hyperarousal has been associated with insomnia, either physiological (increased heart rate, higher frequency EEG) or predominant cognitive-emotional hyperarousal (worry, rumination, repetitive thoughts). Strong evidence shows that those suffering from insomnia with physiological hyperarousal are at higher risk of short and long term severe health problems such as inflammation and hypertension than the group without physiological hyperarousal. The neurophysiological basis of these insomnia phenotypes has however barely been investigated, although its results can have major consequences for how this limiting condition will be treated. To support the development of a differential diagnosis of insomnia, structural and functional brain connectivity in insomnia patients with different levels of hyperarousal will be investigated and related to sleep variables. Investigators will compare the insomnia group to a normal sleeping control group. Investigators expect that the emotion processing circuit (amygdala-ventromedial prefrontal cortex) is a) more affected in insomniacs compared to normal sleeping controls and b) the directionality of this effect to depend on the level and type of hyperarousal in insomniacs. Further, investigators expect c) amygdala activity to be positive correlated with physiological hyperarousal level and d) prefrontal activity to be positively correlated with cognitive-emotional hyperarousal level. Investigators expect a higher physiological hyperarousal level to be reflected in affected afferent pathways of the amygdala towards the ventromedial prefrontal cortex and investigators expect higher cognitive-emotional hyperarousal to be related to affected efferent pathways from the ventromedial prefrontal cortex to the amygdala. Investigators expect sleep quality to play a mediating role in both types of hyperarousal and their brain activation patterns in insomnia patients and normal sleeping controls. These data can lead to the definition of new insomnia phenotypes and to new customized and effective insomnia treatment, focused not only on improving sleep but also on changing dysfunctional hyperarousal levels that currently put insomniacs at risk of numerous severe health problems.
The goal of this study is to identify the prognostic factors of quality of life in patients with psychogenic non-epileptic seizures
Endoscopic sinus surgery (ESS) is a prevalent surgical procedure. It is required in many chronic rhinosinusitis for whom the medical treatment failed. In order to improve the postoperative management of patients treated with ESS, we aim to assess the analgesic action of local injection of ropivacaine in the nasal fossa.
This is a prospective, observational, multicenter study conducted during 1 year in adult and paediatric intensive care units equipped with the EZ-KINOX™ system. A maximum of 250 patients (newborns to adults, suffering from Pulmonary Arterial Hypertension (PAH) associated with cardiac surgery or Persistent Pulmonary Hypertension in the Newborn (PPHN) receiving iNO through the integrated delivery and monitoring EZ-KINOX™ system was planned to be included. The study is strictly non-interventional with the aim of describing current practices and therefore did not affect the patient usual management.
The objective of the project is to establish the 3D velocity mapping of the hepatic vasculature and its consistency
The femoral approach is the preferred vascular access for the set-up of emergency catheters in severely traumatized patient. This location combines simplicity and speed of installation, it allows the simultaneous set-up of arterial and venous catheters, and is a provider of few complications and failures. The ultrasound guidance has greatly reduced installation times, failures and complications related to the set-up of central venous catheter. This was amply demonstrated in the internal jugular and subclavian site outside of extreme emergency situations (Fragou M et al 2011, Farrell J et al 1997, Karakistos et al 2006). The benefit of ultrasound guidance for the set-up of arterial and venous catheters in the femoral emergency has not been evaluated in terms of reduction in complications. Then the main objective of this study is to demonstrate that the ultrasound guidance reduces early complications related to the set-up of arterial and venous catheters in the femoral emergency, among severely traumatized patient compared to the reference anatomical technique.
The development of the retinal vascular network is generally complete during the 3rd trimester of pregnancy but may continue during the first 15 days of life. This late maturation may cause problems in pre-term births and may result in immature vascularization of the retina, a condition called retinopathy of prematurity. Among the different factors affecting the development of the retinal vasculature, the tissue level of omega-3 polyunsaturated fatty acids (PUFA) appears to be a crucial element, as does the form of the PUFA present in the tissues (nature of the phospholipids in their membranes). This project aims to show a possible association between levels of omega-3 PUFA and the onset of retinopathy of prematurity (ROP).
The study aims to construct and validate a self-administrated questionnaire to assess the patients' perception of patient safety in surgical care units. The originality of the study is to perform sociological interviews of hospitalized patients to assess their own perception on the safety of their care and to create corresponding items which will be included in a new questionnaire. In a second step, patients' perception of patient safety will be assessed in numerous surgical care units in France, in order to analyze the psychometric properties of the questionnaire and consequently to validate the questionnaire. The patients' perception will be compared to the healthcare professionals' perception on patient safety and to the patient safety strategies in place in the care units.
RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. AGuIX particles may increase the effectiveness of radiation therapy by making tumor cells more sensitive to radiation. PURPOSE: This first-in-man Phase I trial will study the side effects and best dose of AGuIX when injected together with whole brain radiation therapy in treating patients with multiple brain metastases. The effectiveness of the combination of AGuIX and radiation therapy will be also assessed.
The purpose of this study is to assess the degree of agreement of the measurement of differential renal function in living donors by CT (computed tomography) and SPECT (single photon emission computed tomography).
