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.
Platelets are circulating blood cells. They bind to each other and to the damaged vessel wall to prevent excessive bllod loss. Unlike quantitative platelet defects, there is no automated, simple test to diagnose qualitative platelets defects. However, these defects expose to bleeding in a surgical situation and could explain the transfusion inefficiency of some platelet concentrates. In recent decades, considerable progress has been made in understanding qualitative platelet disorders. In this project, we propose to submit blood donors to a standardized hemorrhagic diathesis questionnaire and to compare the prevalence of platelet function abnormalities in blood donors with and without hemorrhagic diathesis.
The indications that motivated the decision to transfuse (or not) were analyzed to verify compliance with HAS recommendations. Medical records from 57 premature infants < 32 weeks hospitalized between 2016 -2017 were retrospectively analysed, especially all the events related to monitoring of hemoglobin level and RBC transfusions during the first month of life. The criteria (postnatal age, rate of haemoglobin, type of breathing assistance, oxygen needing, medullary regeneration) on which rely the decision process in the HAS algorithm for the RBC transfusion were also considered, as well as the final decision actually adopted for each case (transfused/ not transfused). All this made it possible to determine the kappa coefficient for evaluation of agreement with HAS new guidelines in the investigator's medical staff.
Pancreatic cancer has a 5-year overall survival rate around 5%. It is the 6th most common cancer in France (11 600 new annual cases in 2012) and the 4th leading cause of cancer deaths in France and Europe. Many translational research has tried to identify biomarkers in pancreatic cancer. Only the expression of hENT1 evaluated on the tumor tissue with the mouse antibody seems really relevant by providing a predictive value of the effectiveness of gemcitabine adjuvant. In a metastatic situation, there is no predictive marker of the effectiveness of chemotherapy treatments. GemciTest(TM), studied in this study, is developed by the company Acobiom. Test based on the qRT-PCR technology that allows the establishment of a molecular signature of 10 genes that showed its interest as a biomarker in 60 patients with metastatic pancreatic adenocarcinoma treated with gemcitabine. Retrospective analysis differentiated 2 patient populations: - 22 patients with a "favorable" expression gene with a median survival of 14.9 months - 35 patients with an "adverse" expression gene with a median survival of 5.1 months Primary objective: To evaluate in patients with pancreatic cancer, treated with Gemcitabine alone or combined (nab-paclitaxel) or with Folfirinox, the prognostic value of the GemciTest(TM) test on overall survival and response to treatment. To realize this study, only one 2.5 mL blood sample is taken before starting chemotherapy. The standard practice data is then saved. 100 patients will be included.
Patients will be recruited on each site according to inclusion criteria. Participants willing to participate will received an information sheet and a consent form. After given their consent to participate, they will receive a questionnaire composed of 13 choice questions. In this DCE, patients will be asked to choose which one of two hypothetical patients (Patient A and Patient B) suffering from sarcopenia with different levels of outcomes deserves the most the treatment. After completion of the choice tasks, respondents will be asked how difficult they found the choice tasks on a seven-point scale and to questions on their socio-economic and disease characteristics.
The current study aimed to estimate the one-year incidence of unfitness for the job in an occupational health service, and to describe their aetiology and the characteristics of the unfit employees
Lymphomagenesis is partially known, and some risk factor are identified like those inducing immune deficiencies: chronic exposure to HIV, immune suppressor therapies or commun variable immunodeficiency. Parts of the mechanisms leading to NHL development after pesticide exposure are the disruption of immune surveillance against cancer cell. Pro-oncogenic action of metabolites is the most important mechanisms of action for pesticides. Thus, pesticides are metabolized in pro-oxidant compounds disturbing the redox homeostasis in the haematopoietic and immune cells precursors, promoting proliferation and survival, and inducing DNA breaks. Some of them induce direct DNA breaks and non-conform reparation, leading to activation of oncogenes; and other induces transcription factors for oncogenic signalling pathways. DNA reparation and adaptation to a higher ROS level are associated with resistance against cytotoxic chemotherapy treatment with induction of detoxification mechanism by tumour cells. That DNA repair pathways, which are targeted by chemotherapy could also explain a part of chemo-resistance. It was therefore suggested that DLBCL dependence to specific DNA repair pathways could be targeted to hamper repair of intrinsic DNA damage occurring during B-lymphoma cells proliferation or to increase DNA damage induced by chemotherapy.
Performing a phenome-wide association study (PheWAS) identifying clinical diagnoses associated with a polygenic predictor of Thyroid stimulating hormone (TSH) levels identified by a previously published genome-wide association study (GWAS). PheWAS will be applied in an electronic-health-record (EHR) cohort including North American (n: 37,154) and European participants using 1,318 phenotypes.
this study evaluates of the efficacy of sodium oxybate on excessive daytime sleepiness using Epworth sleepiness scale over 8 weeks compared to placebo
The purpose of this study is to assess the efficacy of INCMGA00012 in participants with locally advanced or metastatic squamous carcinoma of the anal canal (SCAC) who have progressed after platinum-based chemotherapy.
Pneumococcal infections are frequent and serious. Streptococcus pneumoniae is the leading cause of community-acquired pneumonia in adults. In metropolitan France, there are 6000 to 7000 bacteremic pneumococcal infections each year, with a mortality rate of 10 to 30% in adults. To fight against these bacterial infections, vaccines have been developed. At a time when antibiotic savings and the fight against antimicrobial resistance are major public health issues, vaccination is a first choice option to slow the development of pneumococcal resistance. Thus, after these different actions, the proportions of pneumococci with decreased susceptibility to penicillin G fell from 53 to 22%. While there is a significant decrease in invasive pneumococcal disease in children since the use of conjugate vaccines (vaccination of up to 94% of children), the rate of invasive Pneumococcal disease in adults has decreased less significantly. In March 2017, the High Council of Public Health (HCSP) proposed the vaccination of all non-immunocompromised adults at risk and immunocompromised patients. Awareness-raising among vaccinating physicians seems essential, especially in recent years when the value of vaccination is threatened by speculation about its efficacy and toxicity. However, the investigators know that vaccination aims not only to protect the individual, but also the population, especially children and the elderly and the fragile people. Thus, in the context of pneumococcal vaccination, identifying one or more profiles of patients at risk in the absence of vaccination could be particularly beneficial. Indeed, if the physician knows about the population at risk of not being vaccinated, it will be better able to identify patients at risk of not being protected against pneumococcus.
