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 this study is to know the difference between protein profiles (multi-analyte profile) of PH1 patients, idiopathic hypercalciuria (IH) patients and PH1 patients 'siblings. Idiopathic hypercalciuria is a less severe kidney disease that PH1, which also leads to the formation of kidney stones. The aim is to identify patterns of discriminating markers associated with primary hyperoxaluria type 1 (PH1) that will significantly improve clinical diagnosis and prognosis.
Alzheimer's disease and related syndromes (AD) is a disease affecting memory but also the relationship with the environment and empower people. Patients with AD present in 90% of cases of behavioral disorders and of these behavioral disorders include agitation, apathy but also sleep disorders by circadian rhythm impairment.. No study has shown proven efficacy on the behavior of patients with AD. The main objective of the study was to assess the influence of environmental light nighttime sleep of residents.
Management of analgesia and sedation is an integral component of the medical care of a critically-ill child. Its role is to assure comfort and safety to a patient undergoing painful cares and technical procedures; it can also be, in particular situations like acute respiratory distress syndrome or acute brain injury, a full processing treatment. Sedation involves, most of the time, the association of an opioid and a sedative. The use of these drugs is difficult in children, because of a specific metabolism, inducing tolerance and withdrawal in case of prolonged administration. The COMFORT-BEHAVIOR (COMFORT-B) scale is a validated, simple, reliable and reproducible score evaluating sedation and analgesia. Sedation scoring systems must be used regularly to avoid inadequate sedation. Excessive sedation is associated with poor outcomes like prolonged mechanical ventilation, longer hospitalisation and more frequent withdrawal symptoms. Adult and paediatric data suggest that goal-directed sedation algorithms allow a more appropriate adaptation of the treatment to the patient's need and permit a reduction in the duration of mechanical ventilation. The objective was to evaluate the impact of a nurse-driven sedation protocol in a paediatric intensive care unit on duration of mechanical ventilation, total doses and duration of medications, Paediatric Intensive Care Unit (PICU) length of stay, incidence of ventilator-associated-pneumonia and occurrence of withdrawal.
Borderline personality disorder (BPD) is characterized by a pervasive pattern of instability and impulsivity. Several North American prospective studies support the high level of mental health care utilization in this population. There is little data in other systems of health organization, such as France. Furthermore, little is known on the variables associated with the mental health service utilization among BPD patients. The main objective was to compare the utilization of mental health care among BPD patients, to the general population and patients with another personality disorder (PD) and to describe the demographic and clinical factors associated with the group of patients who use the most health care.
Sickle cell disease (SCD) is an inherited disorder characterized by recurrent painful crises with ischemia resulting from vascular occlusion. Adults with SCD have increased arterial stiffness and reduced flow-mediated dilation (FMD), due to impaired release of substances such as nitric oxide. The present study assess the vascular properties of carotid and brachial arteries in children with SCD compared with a control group without cardiovascular risk factors.
Adolescent idiopathic Scoliosis (AIS) is the most common spine pathology. It is opposed to secondary scoliosis due to chronic diseases. Many hypotheses have been made to elucidate the origin of this illness. Recently, the melatonin pathway has been investigated as pinealectomy of the chicken creates a scoliosis that resembles AIS and melatonin supplementation reverses the process. In addition administration of melatonin to AIS patients improved the pathology. However this hypothesis has shown controversial results. Recent studies have demonstrated melatonin cellular resistance in osteoblastic cells from AIS patients. Melatonin acts through G protein coupled receptor (GPCR), mainly using the Gi pathway. In AIS osteoblasts, this pathway is blocked leading to a decrease in the inactivation of the adenylyl cyclase and therefore maintenance of high level of cyclic adenosine monophosphate (cAMP) concentrations in the cells. As modulation of cAMP is important for osteogenesis such resistance may be critical for the initiation or the development of AIS. Gi signalization is used by several other GPCR, thus, this hormonal resistance could logically be found in other hormonal or mediator pathways. A precedent study previously focused on ghrelin in AIS, and demonstrated that AIS patients possess elevated plasmatic values of ghrelin. This study also observed decreased response to ghrelin in AIS cultures osteoblasts.
The risk of delayed cerebral ischemia (DCI) after subarachnoid hemorrhage (SAH) is associated with large cerebral artery vasospasm, but vasospasm is not a strong predictor for DCI. Assessment of cerebral autoregulation with transcranial Doppler (TCD) may improve the prediction of DCI. The aim of this prospective study was to assess the value of TCD-derived variables to be used alone or in combination for prediction of DCI
The objective is to compare women's platelet answer in the last month of pregnancy to women old enough to procreate, no pregnancy and without hormonal treatment. The hypothesis of research is that the decrease of platelet answer in pregnant women could not only limit the occurence of embolic accidents but also explain the lowest incidence of the arterial thrombosis in comparison with the venous thrombosis.
Background / Rationale at. The mild head injury. In France, the incidence of head injuries is estimated at 100,000 per year in France. 80% of mild head trauma. This is a pattern of frequent use of the health system. The reason for consultation, benign appearance, present a significant risk of complication. In 15 to 25% of the evolution of head injury is unfavorable. Disorders of attention, memory disorders, psychiatric events and mood changes may occur. These symptoms are grouped into a syndrome, post-concussion syndrome. The post-concussion syndrome: It affects approximately 20,000 people per year in France. This is a common disease and most undervalued in the general population. diagnostic criteria post-concussional disorder according to DSM-IV (Diagnostic and Statistical Manual). Symptoms may persist for more than 3 months after head injury. This syndrome is responsible for suffering, personal and professional sound and quality of life of patients. It is particularly debilitating in everyday life, and can have disastrous consequences on their family, social, cultural and professional. It gives rise to many financial implications with compensation requirements and expertise consultations. Intention of work In a recent study by a team of neuropsychologists Kremlin Bicetre, it has been shown that screening and early treatment of post-concussion syndrome from the slight head injury prevents chronicity of symptoms.
Pericardial syndrome includes pericardites acute pericardial effusion and cardiac tamponade, recurrent pericarditis squeezing chronic pericarditis. The etiologies are very numerous and can be classified as infectious, neoplastic, metabolic or systemic, toxic causes. Diagnosis is difficult, and 80% of etiologies remain classified idiopathic. In their laboratory to improve the diagnosis of this syndrome investigators have developed a strategy of systematic prescription of biological tests by kit. This prescription by 'kit' strategy proved its interest by comparison with an intuitive requirement of biological. In this study investigators want to improve the diagnostic causative of pericarditis by implementing a new diagnostic strategy. This new strategy includes (i) samples additional less invasive for the patient, the swab pharyngeal and nasal, (ii) the addition of at the outset of more effective diagnostic techniques: specific Polymerase Chain Reaction (PCR)
