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.
Acute kidney injury (AKI) is a common disorder and associated with high morbidity and mortality. However, distinguishing transient AKI from persistent AKI may help in individualizing treatment and limit short and long term consequences of AKI. Previous studies suggested usual urinary indices to perform poorly for separating transient from persistent AKI in an unselected population of critically ill patients. The recent KDIGO (Kidney Disease Improving Global Outcomes) guidelines underlined the need for additional strategies in estimating renal short term prognosis. Recently, a Furosemide stress test (FST) was validated in a cohort of unselected critically ill patients. This stress test performance was found to be good in predicting capacity to identify those patients that will progress to advanced stage AKI. Additionally, FST performance was higher than those of usual renal biomarker. The limited sample size of this preliminary study however precluded adjustment for usual confounders including oliguria. The primary objective of this study is to assess diagnostic performance of FST in differentiating transient and persistent AKI. Secondary objectives are to assess diagnostic performance of FST in predicting need for renal replacement therapy, and to confirm FST results after adjustment for confounders.
Recent data published by various laboratories as well as our preliminary data tend to prove that near-infrared spectroscopy can be used to determine the lateralization of language as part of the preoperative assessment for drug-resistant epilepsy. The reference test used up until very recently was the Wada test, which consisted of injecting an anaesthetic (generally amobarbital sodium) into one of the internal carotid arteries (right or left) in order to determine the predominant cerebral hemisphere for language. This invasive test has been progressively replaced by fMRI, which is nevertheless difficult to perform in children under the age of 7 years. NIRS therefore appears to be a useful alternative, which, in contrast with fMRI, can be easily repeated and allows simple investigation of the various facets of language (e.g. expressive, receptive). In the GRAMFC unit, the investigators have acquired a unique know-how in the field of high-resolution NIRS, both in epilepsy and in the development of language structures.
Bacterial infections are a major cause of mortality in cirrhotic patients in the context of gastrointestinal bleeding or spontaneous bacterial peritonitis (SBP). Rapid diagnosis of SBP is therefore an important research goal because the gold standard neutrophil count in ascitic fluid cannot be performed 24 hours a day in all healthcare structures. The use of urine dipsticks in ascites cannot be recommended at the present time due to their insufficient sensitivity with an unacceptable risk of false-negatives in the context of a fatal disease for which effective antibiotic therapy is available. Ascitic fluid lactoferrin assay has recently been demonstrated to be a very good diagnostic test for SBP. The investigators plan to conduct a prospective study on lactoferrin as well as procalcitonin (PCT) to determine the best laboratory test(s) for the rapid, automated diagnosis of SBP. These tests will be compared with the Aution® urine dipstick, which has been shown to present better diagnostic sensitivity than the Multistix® dipstick . This single-centre study (Amiens University Hospital) will be performed in the context of routine clinical practice on ascitic fluid that is usually incinerated.
A multicenter, randomized, double-blinded, placebo-controlled study of two dosing frequencies of recombinant Interleukin-7 (CYT107) treatment to restore absolute lymphocyte counts in sepsis patients; IRIS-7A (Immune Reconstitution of Immunosuppressed Sepsis patients). A parallel study will be performed in United State of America to allow a common statistical analysis of the primary end points and analysis for the enrolled patient population.
Holders children with intellectual disabilities have great difficulty in adapting to social situations and relationships.Cognitive impairment associated with intellectual disability are important factors to understand their difficulties in processing social information. In the field of recognition of facial emotions in particular, basic cognitive processes such as visuospatial and attentional functions, are heavily involved.Cognitive remediation is a management tool widely used by practitioners to help patients who experience cognitive difficulties. Currently, no program can meet specific and validated the problems are children with intellectual disabilities manner in their daily functioning.
THEODORA is a prospective pilot clinical trial aiming at first to evaluate and validate the predictive value of the A & MS bioassays on tumor control by radiotherapy.
TRACES trial is a multicenter randomized double blind placebo control therapeutic and pharmaco-biological dose ranging study to measure the effect on blood loss reduction of a single intravenous infusion of two doses regimens (standard dose and low dose) of TA administered at the onset of an active PPH (>800mL) during elective or non-emergent CS and to correlate this clinical effect with the biological effect of fibrinolysis inhibition and the pharmacodynamic measure of TA uterine bleeding and venous blood concentration.
At hospital, short term actions are used (adaptation of meals, oral supplementation…) to fight malnutrition. Oral supplementation can have a positive impact on weight gain. But actions should continue at home, particularly to maintain autonomy for elderly. The hypothesis is that practical workshop about enrichment and interest of foods can help malnourished patients to change their eating habits. The main goal of this study is to evaluate the effects of this workshop on improving nutritional status, measured by Mini Nutritional Assessment
The transient global amnesia (IA) is defined clinically as a temporary suspension and isolated from the ante and retrograde memory, totally regressing within 24 hours. The causes of AI remain unknown. The diagnosis of IA is based on consensus clinical criteria including the absence of associated location marks. In clinical practice, the MRI is often performed in conjunction with clinical examination because it ensures the absence of differential diagnoses, including stroke. The visualization of MRI signal abnormalities related to AI directly dependent on the completion time of the review in relation to the onset of symptoms. Typically, no signal abnormality is visible in the hyperacute phase (ie D0-D1) while punctate appear hyperintense on diffusion sequences in hippocampal structures from J2 to J7 to disappear completely. It has been previously demonstrated that the use of higher values of b and / or a better spatial resolution significantly increases the sensitivity of the broadcasting sequence for the detection of these abnormalities hippocampal signal. At St. Joseph Hospital, Investigators explore the AI suspected patients with diffusion tensor sequence (DTI) on our high resolution 3T MRI. Compared to the classical diffusion sequence, DTI is characterized by the use of a greater number of directions in which the diffusion gradients are applied. One advantage of this technique is to be able to perform tractography of white matter fibers. Thus the "connectome" is a new technique for post-processing of DTI images based tractography and to assess all the networks of nerve fibers in the brain. By this technique, the values of average diffusivity (MD) and fractional anisotropy (FA) can be measured along each of the studied nerve fibers. Group studies thus become feasible to compare quantitatively healthy subjects and patients groups in terms of structural differences within the connectome. The contribution of this technique was recently highlighted in patients with temporal lobe epilepsy.
Venous Thromboembolic Disease (VTE) in SCI patients is very common, its prevalence is 60 to 80% against 10-20% in the general population. The risk of VTE is very important in the first weeks after spinal cord injury, and then declines with a prevalence of VTE slightly higher than the general population after 12 weeks. However there is no prospective study of incidence of VTE in SCI patients after 3 months. The investigators wish to conduct such a study during the year following spinal cord injury with performing venous Doppler ultrasound of the lower limbs 6, 9 and 12 months of the initial injuryassociated with a standardized clinical assessment, to know the incidence of VTE and determine prognostic factors for VTE.
