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 research addresses the question of the number of participants needed to identify as many usability-induced errors as possible in the context of summative usability tests. The research addresses also the impact of the ecological validity of the test environment on the number of usability-induced errors uncovered.
The clinical finding of skin rashes which appear after a vitamin C deficiency in Long Term Care Unit leads us to believe that the institutional diet could predispose to this kind of deficiency. Vitamin C has a key role into the struggle against oxidant stress and is involved into the connective tissue formation of the skin and the vascular endothelium. Vitamin C deficiency affects currently 15 to 25% of the elderly over 65 years old reaching 15% women and 20% men after 65 according to Johnston and Al. It concerns mainly the people in precarious situations (persons without fixed homes, ethyl-smoking persons) and elderly over 65 years. Hypovitaminosis C, defined by plasma level between 5 mg/L and 15 mg/L (28.41 to 85.23 µmol/L), is currently undiagnosed, especially with people with a risk of food deficiency and its prevalence increases with age. The treatment consists of a daily oral supplementation of 1 gram of vitamin C/d for 15 days. A minimum intake of 10 mg/D of vitamin C is required to prevent scurvy and maintain a total pool of 350 mg. A diet modification by a systematic intake of 2 glasses of fresh orange juice and/or the consumption of raw fruits and vegetables would prevent the appearance of scurvy.
The aim of the present study is to compare the effect of an exercise performed 180 or 30 minutes before lunch on the energy intake of adolescents with obesity.
Patients with COPD have lower capability of activating their muscles. At the cortical level, force production is not only controlled by contralateral primary motor cortex but also by ipsilateral motor cortex. The aim of this study is to determine whether ipsilateral areas are functionally impaired in COPD.
Old age (> 60 years) is at high risk to develop major depression disorders (MDD). MDD doubles the risk for subsequent cognitive disorders and dementia. Apathy (i.e. the lack of motivation) is a core problem in depression in older age and is frequently associated with cognitive decline in people who have mild cognitive disorders. The investigator propose here to combine actimetry (the measurement of motor activity using a simple device worn at the wrist) and brain imaging to show that it's possible to measure apathy using actimetry in a population of elders with MDD. Having shown that apathy can reliably be measured with actimetry and that it is associated with brain abnormalities, the investigator will be able to test whether actimetry can predict cognitive decline in elders with MDD and can be routinely used in a day-to-day medical practice.
Limited data is available for end of life care in hematologic malignancies, moreover with thrombocytopenic patients. Thrombopenia is a frequent complication, specific of bone marrow involvement in those diseases or its treatments. Yet, a few studies was interested in, whereas platelet transfusion is the only treatment indicated. As it represent a scarce, limited resource, the ethical principles are in conflict in this setting and there's a lack of recommendation. The final decision is take by the clinician and his patient, but no study exist in representation of the two parts. We provide a qualitative study to understand what this decision is made of.
Little knowledge exist on the short and long-term ophthalmological effect of the dialysis. Some studies stated a variation of the thickness subfoveal choroidal before and after a session of dialyse as well as variations of the coat of optical fibers measured in OCT. The Optical Coherence Tomography angiography OCT is a not invasive imaging technique which is now a part of examinations of investigation in imaging of retina. This technique allows to study the retinal macula vascularization without injection of contrast agent and thus allows to deepen the knowledge in medical domains where the exploration was to limited because of the invasive character of the examinations. The hypothesis of this project is that hemodynamic change during the hemodialysis may lead fine variations of the retinal vascularization in the short-term (the day of the dialysis) but also in the longer term (over 1 year).
Better understanding of the specificities of the vaccine response in patients with COPD
TIPIC syndrome (previously called carotidynia) is a rare entity of unknown cause, where the patient has a temporary cervical pain associated with a suggestive inflammation around the carotid artery. Usually considered as a unique and benign episode, some patients have recurrences and the follow-up is usually short. In this study the investigators aim to evaluate patients who presented a TIPIC episode at least 3 months before, clinically and with a cervical doppler ultrasound
SIFI SpA had developed Eyestil Plus®. It is sterile eyedrops without preservatives with a physiological pH containing sodium hyaluronate. Its intended purpose is to moisturize, lubricate and protect the ocular surface and gives temporary relief to burning, irritation and dry eye-related discomfort, and other complaints induced, for example, by: prolonged use of either soft, semi rigid or rigid contact lenses; exposure to environmental factors (air conditioning, exposure to solar radiation, wind, smoke, pollution, severe climatic conditions, dust); ocular fatigue caused by studying, working, driving or prolonged exposure to electronic devices. Eyestil Plus® is CE marked but not available yet in all European countries. Considering the European regulatory change on medical devices - from a Directive (Directive 1993/42/EEC) to a Regulation (MDR 2017/745) that now requires clinical evidence of device performance and safety; SIFI Spa decided to implement the present clinical comparative performance study. The choice of Vismed Multi® as the comparator has been done since it is the current French standard of care treatment for patients with moderate to severe dry eyes.
