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.
Today, to understand pathogenic mechanisms involved in periodontitis remains a challenge to identify biomarkers or therapeutic targets to improve prevention and screening, as well as the effectiveness of periodontitis treatments. The aim is to characterize, in vivo, specific molecular markers reflecting the activity of the pathology, which could lead to - improve the knowledge of the pathogenesis of periodontitis; - determine target molecules involved in tissue destruction; - determine molecular profiles of patients at local and systemic risk; - determine therapeutic targets For this purpose, biological samples will be collected (plaque, saliva, crevicular fluid) from patients with periodontitis stage 3 or 4 versus patients with a healthy periodontium. Biological samples will be collected before and all along the periodontal treatment. Gingiva explants collection will be sampling within the surgical procedures (if they are needed). The primary objective is to investigate tissue and cellular expression of molecular markers associated with periodontal destruction during periodontitis in relation to periodontal infection and systemic changes in host response. A characterization of the cytokines in gingival fluid and unstimulated saliva (Luminex® technique) of patients with periodontitis versus without periodontitis will be done. The secondary objective is to study the influence of periodontitis on systemic pathologies via serum analysis of molecules and bacteria involved in periodontal destruction. Immunofluorescence evaluation of protein expression and distribution (inflammatory mediators, inflammatory pathway signaling proteins) in gingival explants, characterization of proteases (MMP) present in gingival fluid and unstimulated saliva (Luminex® technique) and microbiological analysis of the subgingival biofilm (by quantitative PCR).
This study aims at evaluating, in chronic kidney disease patients on dialysis, the effect of acute per- or pre-dialytic physical exercise on regional myocardial function and myocardial stunning, blood viscosity, arterial stiffness, variability of sinus rhythm, dialysis efficacy, inflammation, mineral and bone disorders, myokines and cardiac remodeling markers.
Undernutrition is a frequent problem in hospitals (at least 30% of patients, SENECA-NHANES studies). Its impact on morbidity and mortality is well known in gerontology, oncology and intensive care. There are very few neurovascular studies dealing with the consequences of undernutrition present before the stroke. Indeed, most of the medical literature concerns only undernutrition acquired after a stroke. The investigator propose to analyze medical data from a cohort of patients over 70 years of age thrombolysed and/or thrombectomized in the neurovascular department between the years 2014 and 2019.
To better characterize the neonatal hypotonia associated with in utero exposure to antidepressants, so far limited to clinical cases, we will perform an observational retrospective pharmacovigilance study, using two databases. First, disproportionality analysis in Vigibase®, the World Health Organization global database, will be perform between antidepressant drugs and neonatal hypotonia . Second, narratives from the French National Pharmacovigilance Database will be extracted.
BIOTRONIK cobalt chromium balloon-expandable Dynetic-35 stent in association with Passeo-35 Xeo peripheral dilation catheter for the treatment of peripheral iliac lesions
The study will be offered to all women who are consultant for an abortion plan are seen in consultation at the orthogeny center where the study will be conducted. Of these 700 women, about 10% will not agree to participate in the study and 10% will not meet the inclusion criteria. Thus it's plane to include 560 patients in the study.
The objective of this single arm, post market, clinical study is to evaluate the performance of Gynecare TVT EXACT® Continence System in women undergoing retropubic mid-urethral sling surgery for Stress Urinary Incontinence (SUI).

A Global, Phase 2 Study of ARX788 in HER2-positive Metastatic Breast Cancer Patients who were previously treated with T-DXd
Chronic idiopathic pruritus (CIP) is a frequent and disabling condition, for which there is no specific treatment. It was shown previously that hypnosis can relieve painful sensations. Pain and pruritus share many similarities regarding sensory receptors and pathways, suggesting that hypnosis might help relief CIP.
