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.
Squamous cell carcinomas (SCC) are the second most common skin cancer in humans. The incidence of SCCs in the USA in 2012 was estimated at 700,000 casesSCCs have a metastatic course in 3% to 5% of cases that is of poor prognosis. In men, the SCCs of the scalp represent the most frequent location of the head and neck, the 3rd location of the whole body. The SCCs of the scalp are more undifferentiated than in other locations. In addition, actinic keratoses of scalp, precursors of SCC, are more resistant to treatment than in other areas. These particularities of the SCCs of the scalp suggest the existence of specific factors at the epidermis level of the scalp. UV-induced damage to DNA is the defining event in skin photocarcinogenesis. It has already been shown that DNA damage induced by UV and the kinetics of repair of this damage may vary with age or phototype of patients, but the topographic variation of DNA damage has never been studied, although it is known that gene expression in skin cells may differ from one region of the body to another. the hypothesis is therefore that the particular characteristics of KAs and SCCs at the scal level could be explained by an increased sensitivity to UV-induced damage. It is planned to study UV-induced damage and its repair at the scalp level in humans compared to the forearm.
Preoperative anemia, bleeding and transfusions have been recognized as a "Deadly triad" in cardiac surgery associated with an increased morbidity,mortality, and costs related. Thus strategies to reduce unnecessary RBC transfusions and to optimize preoperative anemia must be developed .The study evaluate an individual blood conservation strategy based on patient blood management bundles in cardiac surgery patients: optimisation perioperative hemoglobin level by erythropoietin and ferric carboxymaltose (Ferinject) associated with the use of ScV02 to guide perioperative erythrocyte transfusion.
The 22q11.2 microdeletion syndrome (22q11.2DS) is a rare disease with a psychiatric phenotype. Indeed, the diagnosis of schizophrenia is made in 5 to 10% of adolescents and 25 to 40% of adults carrying the 22q11DS. Thus, although this pathology has been able to provide a genetically homogeneous model for the study psychosis etiology, it is not currently possible to establish a link between genomic rearrangement and psychotic symptoms. However, this robust model of genetic vulnerability could provide us a lot of translational informations about schizophrenia genetics. To go furthermore, twin studies have provided us precious data for the study of hereditary diseases. Combining this two approaches, the translational 22q11.2 project proposes a molecular study of two monozygotic 22q11.2DS twins discordant for the psychiatric phenotype -one carrying schizophrenia and the other having no psychiatric symptoms-.
Achieving the optimal sedation level for patient management is not always possible using our standard intravenous medications in Pre-hospital Emergency medicine. Inhaled sedation is possible with the Anesthetic-conserving device with a standard respirator. The pharmacodynamics and pharmacokinetics of halogenated agents allow deep sedation quickly after absorption. The feasibility of inhaled sedation has never been studied in hospital.
Continuous Positive Airway Pressure (CPAP) is the reference treatment of patients suffering from Obstructive Sleep Apnea Syndrome (OSAS).This device functions as a pneumatic stent that stabilizes the upper airway, prevents periodic collapses during sleep.The correction of abnormal respiratory events during sleep allows improvement of symptoms related to OSAS and restores quality of life.The purpose of this study is to validate the efficacy of a new CPAP brand developed by Sleepinnov©.
The harmful effects of stress on health professionals are expressed both in terms of their health (physical or mental) and the quality of work (reduced memory capacity, deterioration in patient care). These adverse effects highlight the importance of implementing effective coping strategies and/or early learning of stress management methods in medical training programs. Relaxation breathing techniques coupled with heart rate variability (HRV) biofeedback is one of the new techniques used to reduce the stress level. No research has yet tested the effects of HRV induced by relaxation breathing technique before managing a simulated critical situation.
In the VECTOR trial, the aim is to analyze, in case of SVS+ occlusions, a first line Embotrap II added to CA combined strategy compare to CA alone strategy. Many practitioners are convinced that a first line strategy with CA alone is easy, safe, rapid and efficient. Maybe, after two, three, four ... passes and with the secondary help of a combined strategy, a high rate of eTICI 2b/3 could be reached with a CA first line strategy. But this could go with a higher number of passes, a waste of time and a suboptimal angiographic results (eTICI 2b) due to distal emboli, especially in case of friable, non-well organized, red blood cell rich (RBC) i.e. SVS + thrombi (25-28). This could, be related to worst clinical outcome at 3 months. VECTOR asks a relevant question: Do the invetigators have to add the use of an Embotrap II or III to the CA, from the first passes, in case of SVS+ clots?
This is a biomedical research study on the determination of adrenal steroids. It has been proposed in recent years as a tool for the diagnostic orientation of an adrenal pathology. The main objective is to analyze the distribution of blood and urinary adrenal steroid values in a population of 60 controls. The secondary objective is to establish reference values for each of these parameters, if their distribution permits, and to study the possible link between the blood pressure level, the orthostatism state, the potassium level and these adrenal steroids.
Transferrin saturation coefficient and ferritinemia in diagnosis of iron deficiency
His-Ventricle (HV) measurement is only obtained invasively using transvenous catheters. This kind of procedure is routinely performed but some risks of complication exist. HV interval prolongation is correlated with increased risk of occurrence of complete atrioventricular block which could lead to syncope or cardiac sudden death. A new non invasive, high density and high fidelity system (BioSemi, BioSemi B.V., Amsterdam, Netherlands) can theorically collect such electrophysiological signal using a signal averaging acquisition method. We want to assess the possibility of non invasive HV interval measurement using this new device.
