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.
Self-swabbing requires less personal protective equipment and could allow to test more people and even to do quick self-diagnosis if antigenic tests are available. In a preliminary study on 190 medical students, the investigators have shown that self and conventional swabbing were identically well-accepted with equivalent level of pain and discomfort induced by swabbing. In a sub-group of this sample, the investigators have shown that the quality of the 2 sampling methods were equivalent. The goal of this large study in the general population is to confirm these findings in an adequately powered study. Such results would allow to develop self-swabbing for large screening campaigns and eventually self-diagnosis using antigenic tests.
Endometriosis is an inflammatory condition that is often treated by surgery. MRI and ultrasound are used for the preoperative morphological assessment. Currently, only surgery allows the exhaustive and qualitative diagnosis of lesions. The PET scan, fixing in certain inflammatory pathologies and in certain cases of endometriosis, could refine this assessment by evaluating the location of the lesions.
Normal-protein and low-AGE through raw or rare proteins diet versus normal-protein and high-AGE diet in stage IIIa-b renal failure patients
Almost 85% of new therapeutic molecules are abandoned before the clinical trial stage. Most of these failures currently concern cancer therapies. In order to optimize the development of these molecules and allow the development of precision medicine, an innovative screening device that is as close as possible to in vivo is necessary. For this reason, the platform the investigators are setting up takes into account tumor vascularization as well as the 3D microenvironment. The platform the investigators intend to set up is based on 4 cornerstones: - the formation of patient-derived organoids seems to be the best option to take into account the microenvironment and cellular interactions. - the vascular network: the formation of a peri-tumoral vascular network, either by using HUVECS cells or by using endothelial cells from the patient. - the extracellular matrix, and the set of proteins it contains, is a major element of in vivo interaction. Moreover, the presence of a matrix is a key element for the development of vascularization in vitro. - Functional tumor microenvironment: peri-tumor vascularization is necessary but not sufficient to claim to recreate a tumor microenvironment. It must be functionalized, and this implies the use of a microfluidic system. This ready-to-use platform will be used on tumor biopsies of the patient, to constitute a tool for personalized medicine. This could even be a future component of decision at multidisciplinary board meetings. The main objective of our research is the constitution of organoids derived from the patient in order to select, via a screening device, the best anti-tumor therapy to administer to the patient. A secondary objective is to collect lymphocytes from the patient's blood in order to test the effectiveness of therapies mediated by the immune system (immunotherapy).
Toxoplasmosis is a parasitic disease caused by Toxoplasma gondii and transmitted to humans through the consumption of raw or undercooked infected meat and / or by poorly washed vegetables. It can be transmitted from the pregnant woman to the fetus when infection occurs during pregnancy leading to congenital toxoplasmosis. Once infected, it is considered that the subject harbors cyst forms of the parasite in the muscles and brain for life with a risk of reactivation when immunocompromised. Recently, questions have been raised about the persistence of these cysts. Currently, only serological diagnosis can demonstrate the infection. This is done by detecting IgM and IgG directed against the parasite. Although humoral immunity is useful to diagnose toxoplasmosis, the cellular immunity is responsible of the main protective role during infection with the secretion of cytokines such as gamma interferon. In some situations, the serological diagnosis is limited: in immunocompromised subjects, some immunocompetent patients, in children with congenital toxoplasmosis, in which the anti T. gondii antibodies are no longer detectable. In order to have a true evaluation of the capacities of the immune system of each individual against T. gondii infection, it is necessary to evaluate the effector immune cells. The main objective of this protocol is to set up a cellular test with the stimulation of lymphocyte by T. gondii. For this objective, 20 subjects (10 positive, 10 negative for Toxoplasmosis serology) will be included. The secondary objective will be to compare the cellular diagnosis (evaluation by ELISA of the secretion of gamma interferon in the supernatant of cells stimulated by the Ag) with the serological diagnosis (IgG and IgM Alinity Abbott and Western blot LD Bio) in 3 groups of 10 patients: chronically infected patients, uninfected patients, patients with congenital toxoplasmosis as well as to assess the persistence or not of cellular and humoral immunity against T. gondii in 10 patients who had acute toxoplasmosis with a known date infection more than 10 years. Thus, 60 patients will be included for a total study period of 24 months. This study will thus allow the sponsor to have a clear understanding whether a subject is able or not to react against T. gondii infection.
Antibiotic resistance is a major threat in modern medicine. Overuse of antibiotics is an important driver of antibiotic resistance. However, some authors have shown that up to 50% of antibiotic treatments in critically ill patients are inappropriate, mostly because they are used in patients with non-bacterial infections. In order to improve antibiotic use, several antibiotic stewardship programs have been implemented worldwide. However, only few of them have taken into account the determinants of prescribing behaviors. Yet, these determinants have been shown to play a role among general practitioners of hospital doctors. Nevertheless, none of these factors have been studied among intensivists. The current project represent phase 1 of the study : construction and validation of a questionnaire.
Assess the values of train-of-four ratios with the TetraGraph and thoses obtained with the TOFscan during recovery of neuromusculat function in surgical patients who have been administred rocuronium. Primary outcome : value of TOFratio with the TetraGraph when TOFratio of TOFscan is greater than or equal to 90% Pilot study : no hypothesis
Isolated tubal torsion is a very rare event already in adults (1: 1.5 million women), it remains exceptional in children without being able to find a prevalence in the literature. The causes can be malformative or idiopathic, but even that remains unknown. Because of the scarcity, surgical treatment is not standardized and left to the good care of the surgeon in charge.
In France, stroke is the leading cause of non-traumatic acquired motor disability in adults, the second leading cause of major cognitive impairment, and the third leading cause of death in men and women. The average age of onset is 73 years (70 years for men, 76 years for women). All types combined, approximately 100,000 patients are hospitalized for stroke each year, approximately 40,000 people die and 30,000 have serious after-effects at one year. The spectrum of functional sequelae ranges from motor and sensory impairment to cognitive impairment; moreover, 30 to 50% of patients have a recurrence within 5 years. Data from the Dijon Stroke Registry showed in 2011 that only 36% of people who had a stroke between 2000 and 2009 were symptom-free 1 month after the event; 22% of patients had mild or moderate disability according to the modified Rankin Scale (mRS); and 42% were unable to walk without assistance or had died. Based on 2009 self-reported data, more than one in two (51%) of those with a history of stroke with sequelae reported significant difficulty or inability to walk 500 meters; 45% had difficulty with at least one activity of daily living. The mortality rate was 44.7 per 100 000 persons in 2013. Cerebral infarctions (CIs) account for the majority of strokes (70-75%). In 2014, despite a 12.5% decrease from 2008, hospital case fatality for CIs remained high at 9%. In 2015, the case fatality rate was 10.7% at 30 days and 11.9% at 1 year. Thirty-day mortality alone concentrated nearly half (47%) of the 1-year mortality.
Sleep Apnea Syndrome (SAS) is highly prevalent in acute stroke and it is related to worst outcome. We aim to assess if SAS treatment, started immediately after acute ischemic stroke, impacts infarct growing and clinical prognosis.
