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.
According to 2011 HAS recommendations, early detection of Alzheimer disease is the major objective in order to allow an earlier care and support. These recommendations strengthen general practitioner role, who plays a key role in the identification of cognitively impaired patients. HAS recommendations are the use of MMSE like test (Mini Mental State Examination) at general practitioner office. A self-screening test, without medical presence, would allow a self-administered cognitive assessment by the patient. A review of the literature about self-administered cognitive tests has been realized. The Self-Administered Gerocognitive Examination (SAGE) has been chosen. It is a brief, valid and reliable cognitive assessment tool, rated on 22 points, which allows an early detection of cognitive impairment, with a sensitivity close to the MMSE test. Nevertheless, SAGE has never been tested at home without medical supervision. In this study, the investigators will determine if SAGE scores at home correlates with MMSE scores at general practitioner office. Patients with inclusion criteria will be recruited during the general practitioner consultation and will have a clinical assessment included MMSE and clinical data collection. Then, SAGE will be given to the patient in order to be completed at home without medical supervision and send to the general practitioner.
This study purpose is to evaluate the association between Retinal Vein Occlusion and Obstructive Sleep Apnea.
Many factors are known to influence the acquisition of bone capital, especially estrogens in women. Estrogens have a major role in bone growth and the acquisition of bone mass peaks during puberty. This peak of bone mass is an important determinant of the risk of osteoporotic fracture in adulthood. It is known that estrogen deficiency increases the rate of bone remodeling and engenders an imbalance between resorption and bone formation, which can lead to osteoporosis. Oral estroprogestin contraceptives have an anti-gonadotropic effect and suppress estrogen secretion by the ovaries. However, studies in adolescents and young adults are rare and evidence of an effect on bone is still inconclusive, although there is increasing evidence that oral estroprogestin contraceptives in teenage girls may compromise the performance of the bone mass. Macro progestins treatments are prescribed in France to patients with contraindications to estroprogestin treatments. This practice is french and few recommendations exist on the use of these molecules by the oral route. There are no studies that describe the impact of these oral treatments on the bone health of young women treated. The Department of endocrinology, gynecology and pediatric diabetes of Necker-Enfants Malades hospital, follows many young girls taking a macro progestin treatment. This study is exclusively descriptive and will focus on the clinical and medical datas available on the bone health of these patients.
Lipin-1 deficiencies are responsible for severe rhabdomyolysis and muscle pain in childhood. A specific treatment does not exist. Our research team (Pr de Lonlay, Pr Van-Endert, Marine Madrange and Perrine Renard) identified the mechanism of this disease and propose a treatment to decrease rhabdomyolysis outcome and muscle pain. Further to a CPP approval in 2015, several patients have been treated by Hydroxychloroquine Sulfate off label use on a compassionate basis. The objective of this retrospective study is to describe the safety and efficacy of Hydroxychloroquine Sulfate given on a compassionate basis to patients suffering from Lipin-1 deficiency within a period between 6 and 36 months.
Sarcopenia is a loss of muscle mass and function that develops during aging. But sarcopenia is also observed in several other conditions: chronic diseases, cancers, viral infections, renal / respiratory insufficiency, immobility, obesity with low physical activity. This sarcopenia is named secondary sarcopenia to distinguish it from the age-associated primary sarcopenia. During prolonged hospitalizations in intensive care, a significant loss of muscular mass and function is also observed. This acute sarcopenia or Intensive Care Unit-Acquired Weakness (ICU-AW) may persist for several months after discharge from hospital. In addition to the loss of autonomy, the reduction of muscle mass has important metabolic implications, ranging from insulin resistance to modification of myokines production. Sarcopenia greatly increases the morbidity and mortality of patients regardless of its cause. The aim of our project is to identify the molecular mechanisms implicated in sarcopenia from different origin. We will particularly focus our work on the metabolic properties, the proliferation/ differentiation and regeneration capacities of the satellite cells (adult muscle stem cells). These satellite cells will be purified from quadriceps biopsies of human volunteers recruited at CHU Montpellier. These satellite cells will also be used to test the ability of some wild aromatic plants from south of France to improve cell survival and differentiation. This will allow us to identify the molecular mechanisms involved in sarcopenia development and identify potential therapeutic molecules.
General anesthesia (GA) is a state of loss of consciousness induced by anesthetic products. In a GA, two classes of products are usually used: on the one hand, hypnotics that are responsible for the sleep component (hypnosis) and memory loss (amnesia), and on the other hand opioids that have an analgesic role. The doses of hypnotic and morphine necessary to achieve this state of loss of consciousness and lack of response to painful stimulation vary from subject to subject, and during surgery depending on the intensity of the stimulus, requiring permanent adaptation to avoid overdose or underdosing, responsible for morbidity. Several monitors of the hypnotic component have been developed in recent years, which can now be used routinely, such as the Bispectral Index (BIS) or Spectral Entropy. However, there is currently no clinically validated technique for monitoring pain or the effect of opioids in the operating room. Spectral analysis of the electroencephalogram (EEG) revealed a significant decrease (-30%) in alpha spectral power, observed specifically in painful experimental conditions in healthy awake subjects. On the other hand, a painful experience is accompanied by transient changes in various parameters under vegetative control, whether cardiovascular, cutaneous or pupillary, essentially underpinned by the activation of the sympathetic system. The investigators hypothesize that a real-time dynamic analysis of the spectral power of EEG combined with that of cardiovascular vegetative parameters, cutaneous conductance and pupillary diameter is likely to be a marker of nociception under GA.
The study aims to investigate the inflammatory response of endothelial cells to various stimulations, in particular the production of IL33 and of endocan in response to allergens, agonists of microorganisms and pollutants. For that purpose, this project attempts to set up a biological collection of lung and umbilical cord endothelial cells. Lung endothelial cells are resected from a surgical specimen, resulting from a lung cancer surgery. Umbilical cord-derived endothelial cells are taken from the umbilical cord collected during the delivery.
A pioneer study demonstrated a proof of concept for IS-FISH with the new ISX technology. This state of the art technology has been recently acquired by the CHU of Amiens. In the present study the investigators want to establish a workflow for simultaneous immunostaining and characterization of FISH cytogenetic pathological signals with the imaging flow cytometer ISX, such as chromosomic gains, losses and translocations in multiple myeloma (MM). The gold standard technology for the detection of prognostic cytogenetic aberrations in MM is a FISH analysis after bone marrow (BM) plasma cells sorting (PCS).2,3 In MM, plasma cells isolation is usually based on CD38 and/or CD138 expression. Cytogenetic risk stratification is guided by the detection of 4 chromosomal aberrations: TP53 and CDKN2C deletions, CKS1B gains and t(4;14) translocation. Thanks to ISX technology the investigators may avoid cumbersome task of cell sorting (outsourced service for our hospital) meanwhile measuring precisely and qualitatively aberrant FISH signals on a large amount of cells.
