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.
Venous congestion in transplanted or re-implanted tissues remains a common and chal-lenging complication in plastic and reconstructive surgery. Local application of medicinal leeches is effective to reduce postoperative venous congestion of the flap and to restore normal blood flow. However, leech therapy is associated with a number of risks, including infections. Indeed, leeches maintain a symbiotic relationship with Aeromonas species in order to digest blood in their gut. Aeromonas spp. infections can occur 1 to 30 days post-application of leeches and are associated with a dramatic decrease in flap salvage rates (88 to 30%). For these reasons, prophylactic antibiotics and, external decontamination are widely recommended throughout the course of leech therapy. The aim of this study is to investigate the prevalence of side effects (anemia and infection) from patients treated with leeches in French Hospital.
Because of metastatic Non-Small Cell Lung Cancer (mNSCLC) and its treatments, patients suffer from numerous symptoms such as dyspnea, muscle atrophy, pain, fatigue, loss of appetite, altered physical condition and lung function, which may further impair the patient's overall condition. Nevertheless, it has been suggested that physical exercise could improve response to treatment at the clinical level due to its known effects on the immune system. Moreover, preclinical studies have shown that exercise performed during chemotherapy administration could result in physiological benefits such as improved intra-tumoral infusion and drug delivery. The ERICA study aims to assess the feasibility of an acute physical exercise immediately before immunotherapy and chemotherapy administration in patients with mNSCLC.
The objective of this study is to evaluate the effects of regular physical practice on fatigue, quality of life and kinesiophobia in patients treated at the ICO in Angers, regardless of the type of cancer and the type of treatment.
The Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is a new coronavirus discovered in December 2019 in Wuhan, China and currently responsible of a worldwide outbreak and the death of more than 55,000 patients in France. The more severe form of COVID-19 disease induces a pneumonia with profound hypoxemia which may require invasive mechanical ventilation. It is estimated that 5% of COVID-19 patients are admitted to the Intensive Care Unit (ICU) for management. Hospital mortality in patients who develop severe acute respiratory distress syndrome (ARDS) ranges between 40% and 60%. The investigators purpose to investigate the pathological findings of COVID-19 patients who died from ARDS in the ICU by doing post-mortem lung biopsies
Double-blind, randomized, placebo-controlled, Phase 3 study to investigate the efficacy and safety of odevixibat compared to placebo in Patients with Alagille Syndrome.
Posterior cranial fossa craniectomy has been shown to improve patient survival. The level of autonomy, disability and quality of life of survivors has been little studied and still underresearched,. In this context, an assessment of the level of disability and of the quality of life after performing a posterior craniectomy seems relevant.
Introduction: Complex abdominal aortic aneurysms (CAA) are defined as abdominal aneurysms that are anatomically unsuitable for a standard endovascular repair because of a short infrarenal neck or no infrarenal neck. These CAAA are usually treated either by fenestrated endovascular aortic repair (FEVAR) or open repair (OR). Data comparing these thechniques remain scarce, mainly consisting of systematic reviews based on retrospective studies. Although mid-term and long-term results remain uncertain, FEVAR has gained widespread acceptance in the vascular community. However, this practice is not evidence base. Beyond clinical results, whether FEVAR is cost-effective or not is not demonstrated. A randomized controlled trial comparing FEVAR and OR is unlikely to be conducted since centers have developed specific expertise and practice, and most of surgeons are not keen to randomize patients. Thus, we believe that a prospective comparative multicentric cohort, with a propensity score and minimization of selection, classification and confusion bias is the most realistic way to provide reliable comparative data on cost effectiveness of FEVAR and OR. Overall, 382 patients are expected to be included (159 in each group). Objective: The objective of this prospective non-randomized comparative multicenter cohort study is to compare the cost effectiveness incremental ratio at 36 months of FEVAR and OR for CAAA. Method: Patients with CAAA discussed for FEVAR or OR in 37 french vascular centers in during a two years inclusion period constitute the population study. Preoperative and postoperative clinical and imaging data will are collected prospectively in eCRF forms. QOL before and after treatment is assessed by the E5D5L. The follow-up period is three years. The primary outcome is the Incremental cost-utility ratio (cost/QALY) at 36 months. We plan to minimize indication biases by using a proposensity score (proposnsity score maching and Inverse probablility of treatment weighting) based on clinical and anatomic characteristics. Patient at prohibitive risk for OR are excluded. Patient anatomically unsuitable for FEVAR are also excluded . Conclusion: This study should provided valuable data on cost effectiveness of FEVAR for CAAA. Sub-goup analysis will be also conducted.
PTH secretion defects (grouped under the name hypoparathyroidism) are due to abnormalities in the PTH gene, abnormalities in the development of the parathyroid glands which synthesize PTH or abnormalities of the calcium sening receptor whose role is to adapt PTH level to ambient calcium level. In contrast, primary hyperparathyroidism in children is also exceptional; expressed by hypercalcemia, with a renal and bon risk. Pseudo-hypoparathyroidism, now known under the term inactivating PTH / PTHrP Signaling Disorder or iPPSD, are rare pathologies characterized by resistance to the action of PTH sometimes associated with other symptoms, in particular chondrodysplasia. They are linked to a defect in the action of a factor in the signaling pathway of G protein-coupled receptors that activate the production of cyclic AMP (cAMP). IPPSDs are most often due to a molecular defect in the GNAS gene, subject to parental imprint. Fibrous dysplasia / McCune-Albright syndrome is a rare disease caused by somatic "gain-of-function" mutations in the GNAS gene located on chromosome 20q13 leading to activation of the protein Gαs and inappropriate production of intracellular cyclic adenosine monophosphate (cAMP). The clinical phenotype is determined by the location and extent of the tissues affected by this mutation. Autotaxin (ATX) is a protein secreted by different tissues including the liver, fatty tissue, and bone. Today, ATX is described as the major source of LPA in the bloodstream. LPA interacts with one of its receptors on the surface of the cell membrane. Depending on the receptor engaged, one or more Gα subunits (G12 / 13, GQ, Gi / o or Gs) will activate multiple cell signaling pathways. In bone, ATX is expressed by osteoclasts and osteoblasts. Recent laboratory data have shown that PTH stimulates ATX expression in osteoblasts in a dose-dependent manner. The objective of this study is to provide clinical proof of concept that the PTH / Gαs / ATX pathway is truly significant in physiology and pathology, by studying the full spectrum of PTH and GNAS pathologies. If this proof of concept is obtained, therapeutic applications will probably be possible in the long term.
While absolute quantification in 18F-FDG PET (Positon Emission Tomography) is widely used in clinical routine, absolute quantification in SPECT (Single Photon Emission Computed Tomography) is under development and its clinical interest remains to be demonstrated. Recent studies carried out on bone scan recordings show the potential interest of quantification indexes such as SUV (Standard Uptake Value).
A coronavirus pandemic began on 12/31/2019 with a first Chinese patient. As of 04/04/2020, the epidemic affects more than 190 countries with more than 50 million official contaminations and 1,251,000 deaths. (Univ J Hopkins). This virus causes a pathology ranging from simple flu-like symptoms in 80% of cases to acute respiratory distress syndromes requiring intensive care in 5% of cases and a death rate of 1.4 to 4% of cases. Viral contamination is airborne and fecal A first epidemic wave crossed France in March / April 2020 then a second in October / November with a source of contamination which began in mid-August 2020. The sources of propagation are not well known (what places, what times, what contacts…? ) In the context of the health crisis linked to the coronavirus, knowledge of the sources of propagation of this 2nd wave is an important issue to guide end of lockdown and second lockdown policies.
