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 aim of the study is to understand the structural and functional modifications of the host, the microorganisms, and their interactions (host/microorganism relationship) before and after the RV3278A - ET0943 product application
The main objective of this retrospective cohort is to evaluate the impact of the first epidemic wave during lockdown on bacteremia epidemiology in one French University Hospital.
This aims to clinically validate, on a large population, a tumor detection aid software which has already been trained on a representative French population (from several hospital centers and liberals from several departments in the west and east of France). This population consists of 1000 patients who have been treated for breast cancer (histologically proven by breast biopsy) and whose investigators have mammograms performed at the time of diagnosis. The control population consists of the unaffected breast of each patient (with the exception of the rare cases of bilateral cancers). This innovative software has the main feature of recognizing healthy breast tissue, allowing the radiologist to focus on breast tissue at risk, improving the management of medical time and the management of "difficult" files.
cephaloceles are rare lesions of the petrous apex, inconsistently listed as meningoceles or arachnoid cysts. They're consistent with a herniation posterolateral of the Meckel cavum within the petrous apex. These lesions may be the cause of a symptomatology varied, or be discovered by chance in subjects who have not been asymptomatic. Currently, there is no evidence in the literature a simple, fast and reproducible radiological marker that allows for the diagnosis of cephaloceles of the petrous apex, in particular the small ones. The purpose of this study is to validate a radiological benchmark simple and reproducible, the trigeminal petrol line, in order to improve the diagnosis of petrous apex cephaloceles
Congenital obstructive megaureter is a urinary malformation affecting the ureterovesical junction and causing obstruction to the flow of urine. It is the second most common cause of hydronephrosis. This malformation affects four times more boys than girls and is bilateral in 25% of cases. It is also associated with contralateral renal dysplasia in 15% of cases. The obstruction is linked to aperistalsis and hypertrophy of the circular muscle bundles and increased collagen 1 level. This malformation is accessible to antenatal screening from the second trimester. It falls within the scope of CAKUT and requires regular monitoring. Indeed, this uropathy can cause repeated pyelonephritis, kidney scarring and affected kidney function.
Banff classification stands as gold standard and international consensus for the identification, diagnosis and categorization of renal allograft pathology. In addition to multiple revision dedicated to the clarification and refinement of these diagnostic categories, a special attention is now dedicated to the development of automated protocols serving the use of artificial intelligence in digital pathology. To be integrated in the actual early post-transplant monitoring procedure, such original approach is considered to match various growing expectations of clinicians and pathologists regarding the future of transplant nephropathology : decrease inter-observer variability, reduce human errors and limit time-consuming analysis of kidney biopsy. Among these, an accelerated reading and access to Banff diagnostic criteria could help initiating both appropriate and immediate treatment to improve graft survival in kidney transplant recipients. Yet conventional histopathology still requires the preparation of a paraffin block, sections as well as subsequent colorations that altogether delay the final pathological diagnosis and urge the need for additional diagnostic modalities. Designed to overcome this critical limitation, the HARBOR study intends to test the performance of direct histopathological examination of fresh kidney biopsy with full-field optical coherence tomography for the identification of Banff elemental lesions and diagnostic categories.
This is a multi-centre, observational, non-comparative, retrospective cohort study designed to evaluate the long-term safety and effectiveness of osilodrostat in non-CD CS patients. Patients treated with oral osilodrostat regardless of the duration of their treatment will be followed retrospectively for up to 36 months after initiating osilodrostat.
Calcifying uremic arteriolopathy (or uremic calciphylaxis) is a rare disease (prevalence <1% of dialysis patients), but the prognosis is often catastrophic. The main non-modifiable risk factors are age, female gender, diabetes, obesity and length of time on dialysis. Today, there is no specific treatment for this pathology, and the therapeutic management is poorly codified. However, it is commonly accepted that the treatment is based on the control of risk factors, local care, and the possible addition of treatment with sodium thiosulfate. Hyperbaric oxygen therapy has also been proposed by some authors, but remains not very accessible in practice. Recently, it has been proposed to use Rheopheresis as an adjuvant treatment for severe forms of uraemic calciphylaxis. It is a technique of apheresis in double filtration, allowing the extraction of molecules of high molecular weight, and thus the improvement of the rheological conditions of microcirculation. The expected effect is the improvement of tissue oxygenation and the acceleration of the healing of skin lesions, with the consequent reduction of infectious complications. The aim of this study is to propose a large national retrospective study, studying the evolution of patients with uremic calciphylaxis and treated by rheopheresis, compared to a control group. This will allow to have a more precise idea of the contribution of Rheopheresis in this indication.
New pain assessment parameter, called the Variation Coefficient of Pupillary Diameter (VCPD) described. This parameter allows evaluating the pain of patients during uterine contractions in obstetrical labor, and postoperatively in recovery room. This parameter also allows evaluating the level of pain in Intensive Care Unit (ICU), in intubated or tracheotomized patients moderately sedated (Riker score 3 or 4).
Hereditary hemorrhagic telangiectasia (HHT) or Osler-Weber-Rendu syndrome patients are carriers of a heterozygous mutation of the activin receptor-like kinase 1 (ACVRL1), Endoglin (ENG) or Mothers against decapentaplegic homolog 4 (SMAD4) gene. HHT involves the Bone Morphogenetic Protein 9 (BMP9)/Activin receptor-Like Kinase 1 (ALK1)-endoglin signalling pathway. BMP9 is a growth factor that binds to ALK1 receptor and to endoglin its co-receptors and physiologically activates Smad signaling pathway. Endothelial cells in HHT patients display half expression of functional ALK1 receptors or endoglin co-receptors or of the transcription factor SMAD4, which should lead to effects on the functions of these cells. The identification of differences in gene expression between endothelial cells from HHT patients and healthy donors will allow the identification of new functions or new target pathways for therapy. Circulating endothelial cells are rare in the bloodstream in adults, but are present in greater quantities in cord blood.
