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.
Familial amyloid neuropathies (FAP) are hereditary disease due to a mutation of the tranthyretin gene (TTR). These neuropathies are severe and life frightening. Asymptomatic carrier of TTR mutation are now detected in large TTR-FAP family. However, it is very hard to detect the moment where a TTR mutation carrier become symptomatic: too early diagnosis exposes the patients to side effect of the treatment and too late diagnosis exposes the patient to disease progression and clinical sequels. Neurological monitoring comprises clinical examination, electrophysiology and imaging. Sensitivity and specificity of these tools are not sufficient and we have to develop new biomarkers sensitive enough to detect modifications under treatment and the moment where a TTR mutation carrier become symptomatic Magnetic resonance imaging (MRI) can well evaluate neuromuscular diseases. Electrophysiological examination is also a good tool to evaluate NAF. MUNIX is a technique that permits to estimate the number of motor unit in one muscl. MUNIX is related to the disability in chronic inflammatory neuropathies and could be more sensitive than clinical scales and other electrophysiological data to detect modification of the disease in TTR-FAP. The objective of this exploratory study is to test the applicability of MUNIX and MRI as early measures for detecting the transition from asymptomatic to symptomatic TTR-FAP. In symptomatic TTR-FAP we will determine if MUNIX and MRI data are related to clinical deficiency and disability of the patients. This is a transversal exploratory study. If we manage to demonstrate that MRI and MUNIX can segregate symptomatic versus asymptomatic TTR mutation gene carriers, we will propose a longitudinal study with a follow up of more asymptomatic gene carriers.
The intermediate coronary stenoses defined by a degree of stenosis from 40 to 70 % are frequent. The Flow Fraction Reserve (FFR), realized during coronarography, is an hemodynamic evaluation by the functional impact measuring the loss of load in upstream / approval of the stenosis inthe basal state and in situation of hyperemia led by adenosine. Further to the study FAME, the threshold of definition of the significant character of one Stenosis was fixed for a value of FFR = 0,80. However, the impact forecasts intermediate values badly known rest. We hypothetized that coronary stenosis associated with borderline values of FFR 0.81-0.85 were associated with a higher rate of clinical events than those with a FFR >0.85
The purpose of this study is to confirm the clinical validity and the performance of the Monocyte Width Distribution (MDW) parameter to detect the development of sepsis in a prospective study of Emergency Department (ED) adults who have blood draw including Complete Blood Count with differential (CBC-DIFF) ordered upon presentation in a Spanish & French hospital and to verify cut-off for Tri-potassium ethylenediaminetetraacetic acid (K3EDTA).
Over 30% of hospitalized patients are malnourished. These figures range from 20% to 60% in geriatric units. Undernutrition results either from a decrease in energy intake, an increase in needs, an increase in losses or a combination of these three causes. As a factor in mortality, morbidity and lengthening the time of hospital stays, undernutrition induces health costs 45 to 102% higher than a person who is not undernourished. The nutritional management of patients initially includes hygieno-dietary advice, then the implementation of an oral nutritional supplementation (ONS). A recent study conducted by our teams highlighted the low ONS consumption among women compared to men (39.48% vs 73.41%). Interviews with patients showed that 13 out of 17 had a negative opinion of ONS. The aim of this study is to show, on a larger scale, whether ONS consumption differs according to sex and if so, to highlight the obstacles to this consumption through the implementation of semi-directive interviews with patients. Ultimately, this research will lead to the implementation of alternative strategies to improve ONS consumption and to a better understanding of the obstacles to ONS consumption.
Patients with unilateral transmission hypoacusis due to otosclerosis undergoing stapedectomy surgery will be prospectively included. They will be undergoing a free field vocal audiometry using the Oldenburg MATRIX software to evaluated the squelch effect gain between audiometry before and after 9months after surgery. Our hypothesis is to show a squelch effect with the rehabilitation of the binaural audition.
The purpose of this study is to determine T-cell mediated inflammatory immune response in some participants previously exposed to atabecestat.
Comparison of subcostal and transhepatic views to measure inferior vena cava diameter by echocardiography in intensive care unit patients
Assess prevalence of urinary functional disorders in women of 40 and more, visiting a general practitioner, occupational medicine or health examination center in Puy-de-Dôme. Study conducted for a month using a self-filled survey distributed by secretaries or nurses.
The EDSS score is the reference tool for rating disability in patients with multiple sclerosis. It is used in both daily monitoring and clinical research studies. Its main shortcoming lies in its imprecise and variable nature, with significant inter-examiner variability. This variability is the consequence of the complexity of the score rating and also of its subjective nature. The application developed aims to reduce the risk of rating error, and to homogenize the results obtained regardless of the examiner and his experience in using the score.
In order to develop an innovative device to study infectious keratitis, we need to illuminate the cornea of patients suffering from an infectious keratitis with red or near-infrared light. Because of technical reasons the shortest possible wavelength (red) presents advantages.
