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.
The goal of this retrospective study is to evaluate the proportion of seroconversion after 2 doses mRNA anti-SARS-CoV2 vaccination in a cohort of high risk liver transplanted patients. Seroprevalence is a secondary objective in order to identify seronegative patients with a history of COVID-19 (ie who lost antibodies) and seropositive patients with no history of COVID-19. The hypothesis is that the degree of immunosuppression is determinant on the seroconversion rate and therefore, although at higher risk of severe forms of COVID-19, liver transplanted patients have a lower chance of being protected after vaccination. Seroconversion rate in previously seronegative and with no history of COVID-19 liver transplanted patients is the main evaluation criteria. The factors associated with the absence of seroconversion will be identified as a potential tool to better adapt the vaccination strategy in this population. The rate of seroconversion after the 1st dose will also be evaluated. Safety of the 1st and 2nd injection will be reported as well as their value to predict seroconversion. A control group of patients listed for transplantation will also be included both in the seroprevalence and the seroconversion analysis. Persistance of the antibodies in long-term after transplantation and after transplantation for the patients who have been vaccinated before transplantation will also be reported.
The surgical technique of Musset has shown its effectiveness for the cure of recto-vaginal fistulas. Recto-vaginal fistulas are mostly post-obstetric (88%). The objective of this study is to investigate the outcome of patients who underwent a Musset surgical technique, as well as their postoperative functional and anatomical results at a distance from the procedure.
The primary objective of the study is to demonstrate that the ECCO2R pulsatile configuration prevents the Willebrand factor high molecular weight multimers decrease observed under continuous blood flow configurations. The secondary objectives are to quantify the CO2 extracorporeal removal in the pulsatile configuration, to describe complications (hemorrhagic, thrombotic and hemolytic), to describe patients' gas exchanges under ECCO2R, to describe the clinical course of the patients under ECCO2R as well as during the whole stay in the Intensive Care Unit (ICU).
Analysis of gut microbiota becomes more and more accessible in recent years. Experimental data in both animal and human studies have demonstrated that imbalance of the gut microbiota which is called symbiosis may participate in an accelerated procedure of ageing as well as the expression of frailty phenotype. People living with HIV (PLHIV) present markers of phenotypic frailty on average 10 years before uninfected people. In this population structural and functional modifications of GALT (Gut Associated Lymphoid Tissue) are observed early after HIV infection and persist despite virological suppression on ART (AntiRetroviral Treatment). These GALT modifications are associated with microbial translocation that is also correlated with immune activation and dysbiosis. The objective of study is to explore gut microbiota of PLWH over 5 years, as well as to study associations of its longitudinal evolution with frailty markers and burden of comorbidities.
This retrospective monocentric study aims at comparing multimodality endoscopic biliary drainage versus percutaneous radiologic biliary drainage in case of perihilar malignant obstruction. Data from patients admitted in the Nancy University Hospital, France, between january 2016 and march 2022 with jaundice and perihilar obstruction will be retrospectively collected.
Assessment of the level of oral comprehension of the intensive care patient is essential to improve their care because they have often troubles like delirium.
The main objective of this study is to find out whether young MSM (men who have sex with men) believe it is important for their GP to be informed of their sexual orientation, in order to improve their clinical, especially with HPV vaccination. The secondary objective is to analyze the state of knowledge about the HPV vaccine and the value of HPV vaccine in this target population.
Operative hysteroscopy (OH) is an endoscopic technique for the treatment of benign intrauterine lesions and in particular uterine fibroids. The limit of this technique is the duration of the operation which is correlated with the operative risks. Thus, when there is a large fibroid or several fibroids, this technique can sometimes not be used or require several sessions. Today there is a new technique of HO that theoretically allows a gain in operative time. There are few comparative studies showing a clinically interesting gain in operating time. The aim of this study is to compare the operative time between the classical HO technique by resection and the vaporization technique. This is a randomized, single-center study. The study population corresponded to women aged over 18 years requiring operative hysteroscopy for fibroids. After obtaining informed consent, patients will be randomized into two groups: a vaporization hysteroscopy group and a resection hysteroscopy group. The primary endpoint will be operative time. The secondary endpoints will be intraoperative characteristics and complications (amount of distension fluid used, cervical injury, uterine perforation), immediate postoperative data (pain) and medium-term data (postoperative synechiae). The starting hypothesis is that the technique of hysteroscopy by vaporization would reduce the operative time by 30%. The number of subjects required per group will be 27 patients, or 54 patients in total over 24 months. The expected results are a significant decrease in operative time with the vaporization hysteroscopy technique. This would be important because the reduction in operative time is associated with a reduction in complications of operative hysteroscopy and the possibility of treating larger fibroids with this technique.
Immunotherapy (IO), such as treatment with anti-PD-1, PD-L1, or CTLA-4 inhibitors, is a rapidly expanding treatment for multiple metastatic cancers with improved survival for certain cancers. However, the optimal duration of immunotherapies is currently unknown. Our hypothesis is that a reduced dose intensity of IO could be as effective as the current standard treatment in term of prevention of the disease progression. If proved right, this study will have a positive medico-economic impact by reduction of the costs associated with the treatment and the toxicity, and an increase of the patients' quality of life.
The purpose of the study is to assess the success of a single administration of Staccato alprazolam compared with placebo both in rapidly terminating a seizure episode within 90 seconds and with no recurrence of seizure(s) up to 2 hours after investigational medicinal product (IMP) administration.
