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.
More than 80% of patients with upper gastrointestinal bleeding (UGIB) are hospitalized after their visit to the emergency department (ED). However, some of these hospitalizations do not seem justified. Several clinical scores have been developed to classify patients according to their risk of death or need for therapeutic intervention. The aims of this study are: 1. to describe the characteristics of patients hospitalized for UGIB after their visit to the ED 2. to assess the predictive factors of hospital intervention or death 3. to assess the accuracy of existing prognostic scores to classify patients according their risk of death or need for therapeutic intervention (external validation) and to identify low-risk patients not requiring intervention. 4. Depending on the results, a new score could be derived to identify patients at low risk for intervention or death.
Methotrexate is one of the immunosuppressants used in chronic inflammatory bowel disease (IBD). It is indicated as monotherapy for induction and maintenance treatment of Crohn's disease (CD), or in combination with anti-tumor necrosis factor (TNF) agents for prevention of immunization. The main objective is to assess the persistence rate of methotrexate treatment in patients followed for chronic inflammatory bowel disease (IBD).
Between 2 and 3 million non-melanoma skin cancers and 132,000 melanoma skin cancers occur globally each year. Sun protection continues to be a major public health issue and has always been a priority research area for Pierre Fabre laboratories. The involvement of ultraviolet radiation of the solar spectrum in skin carcinogenesis is well known, through its ability to damage the DNA of skin cells and the induction of oxidative processes. The aim of this exploratory study is to perform the quantification of: - DNA photoproducts excised from the genome by the biological repair systems in urine samples - cellular DNA damage in the epidermis following chronic exposure to natural sunlight. This study will allow us to better understand and quantify the benefit of sunscreens on photoinduced cellular damage and their elimination in urine.
The facial emotion recognition is a basic social skill for successful social interactions. Several meta-analyses and recent studies found impairments of the perception of facial emotions in patients with euthymic bipolar disorder. Few studies compared recognition of facial emotions impairments during euthymia in patients with bipolar disorder type 1 and 2. These studies included low population samples (N<60). There were discrepancies in results of these studies. Szanto suggested that facial emotion recognition impairments were correlated with suicidal risk and social isolation. These impairments should be taking into account regarding psycho-social treatments in patients with bipolar disorder. This study aims to evaluate facial emotion recognition in patients with bipolar I and II disorders compared to healthy controls, using the facial emotion recognition test (TREF). The objective of the present study is to compare TREF scores in a group of patients with bipolar 1, a group of patients with bipolar 2 disorder and a group with healthy controls. In addition, the investigators will investigate the relationships between TREF scores and levels of self-esteem and mental well-being.
Military personnel are called upon to serve in hot, dry or humid climates, which places great demands on their ability to tolerate heat. Induced heat stress can impair performance and lead to pathologies. Faced with the challenges of global warming, this issue is becoming increasingly important in the practice of sport. While hyperthermia is known to impair endurance performance, the underlying thermophysiological responses and regulatory mechanisms during prolonged exercise remain poorly understood. The effects of hyperthermia on mental performance raise questions about the degradation of interoceptive capacities and the deleterious impact on behavioral regulation, an important component of thermal risk management in ultra-endurance exercise. What's more, despite the muscular and hydromineral consequences (rhabdomyolysis, renal failure, dehydration) of prolonged exercise, few data are available on recovery kinetics. A better understanding of the factors conditioning recovery quality could help limit the deleterious consequences of ultra-endurance exercise.
In this study, the investigators aim to validate a non-invasive marker of fluid-responsiveness in children with acute circulatory failure based on standardized abdominal compression. This would allow physicians to identify which patient could benefit from a fluid expansion, thus avoiding a potentially useless or even dangerous fluid expansion, leading to fluid overload. To this end, the investigators will evaluate the diagnostic accuracy (sensitivity and specificity) of stroke volume variation induced by standardized abdominal compression for the diagnosis of fluid responsiveness (based on the gold-standard test: significant increase in cardiac index after fluid expansion).
Anxiodepressive symptoms are frequently observed in Parkinson's disease patients. These non motor psychiatric charateristics of the disease negatively impairs quality of life, and may impair well-being or therapeutical observance. The objective of this study is to determine if psychological ressources are associated to anxiodepressive symptoms, to parkinson well-being and therapeutical observance. It will be interesting to determine if the presence of some - or multiple- psychological ressources could prevent patients from anxiety, depression, impaired well-being and impaired observance. This study will analyse retrospectively psychological scalescompleted by 30 parkinson's disease patients through previous psychological interviews. The scales investigate anxiety, depression, well-being, psychological ressources, and therapeutical observance. The results will highlight the importance of working on psychological ressources with Parkinson's disease patients through psychotherapy, in order to improve their well-being, positive emotions and maybe contribute to better therapeutical observance.
perform a study in VigiBase® to assess if clozapine was associated with an over-reporting of infections and to characterize those infections. The investigators also decided to assess the dose dependency associated with those infections.
Frequency of Inflammatory Bowel Diseases in children (IBD)-Crohn's disease (CD), Ulcerative colitis (UC) is constantly increasing. Pediatric-onset IBD represent a different nosological entity (from adult IBD) because of their major inflammatory activity, their significant anatomical extent and their stenotic and/or fistulizing character sometimes from diagnosis. Intestinal lesions are due to dysregulation of the intestinal immune system but the cause is unknown. The investigators hypothesize that extranuclear DNA participates in the amplification of the inflammatory response at the intestinal and blood levels during pediatric IBD through the cGAS-STING pathway. The investigators will analyse blood and fecal samples, and colonic biopsies issued from ill children and control participants on age of 6 to 17 years. The investigators think that this study will provide a better understanding of the mechanisms involved in pediatric IBD, assess the place of the cGAS-STING pathway, identify potential biomarkers of pediatric IBD and new potential therapeutic targets based in particular on the inhibition of the cGAS-STING pathway.
Rhizarthrosis (trapeziometacarpal osteoarthritis) is the most common primary osteoarthritis of the hand, and a source of major functional impact, as it affects the thumb. Non-surgical therapeutic means are currently limited to wearing an immobilization splint, analgesics and oral non-steroidal anti-inflammatory drugs. These symptomatic treatments are of limited effectiveness and do not prevent from progression of the osteoarthritis disease. The most effective treatments currently recognized are surgical, but they also have their limits. Cell therapy is considered as a promising approach to treat tissue damage including osteoarthritis. Mesenchymal stromal cells are excellent candidates for achieving this type of result, because they can differentiate into the different tissues from the mesoderm (cartilage, bone, muscle, tendons, fat, dermis, conjunctive matrix, etc.). In addition, unlike cells from the embryonic cord, the risk of teratoma or tumor does not exist. Mesenchymal stem cells have regenerative and immunomodulatory properties but the methods of collection, preparation, combination with substances such as hyaluronic acid, or PRP, or platelet concentrates, will obviously influence the effectiveness of the results. . Nanofat autografts are obtained in a simple way, in a closed circuit, preserving the stromal mesenchymal cells in large numbers with a minimum impact on the cellular elements. The preparation remains simple and inexpensive, but it is nevertheless necessary to characterize these emulsified preparations biologically before using them as cell therapy. The main objective of this study is to characterize a nanofat autograft on a biological level.
