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 hypothesis is that from a cluster defined by a confirmed positive case of COVID-19 and its contact cases, it is possible to study the different expressions and clinical evolutions of COVID-19 infection and to explore the biological profiles related to the observed clinical history. Certain biological determinants (virological, immunological, microbological or gentic) could indeed be correlated with the clinical presentation and/or be useful for personalized care. The main objective is to study the relationship between the biological profiles observed and the clinical evolutions within the same cluster of transmission of the coronavirus SARS-CoV-2 (positive COVID-19 cases and contact subjects).
The purpose of this study is to evaluate the performance of different methods for measuring factor IX activity levels in haemophilia B patients treated with eftrenonacog-alfa and assess its pharmacodynamics (PD) in a real-life setting.
The recent and unexpected occurrence of patients with the development of skin lesions on the hands and/ or feet has been described recently. As these cases occurred contemporaneously with the Coronavirus Disease 2019 (COVID-19) and as it was the most often occurrence of de novo frostbites, the question raised of whether there is a direct link between the occurrence of these lesions and infection of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) the responsible for CoVID-19. Indeed, mechanisms of these lesions and the precise correlation with Sars-CoV-2 remains poorly understood. Therefore, this study aim to: 1. Determine the possible link with this virus, 2. Understand the mechanisms involved in the pathogenesis of these lesions.
The psychoBehçet'study is aimed at evaluating the psychological and neurocognitive symptoms in 25 consecutive patients followed for Behçet's disease. This is a monocentric, observational, non interventional study.
Migraine is very frequent (15% of the general population). During attacks, many subjects with migraine have allodynia (pain induced by normally non-painful stimuli), photophobia (hypersensitivity to light), phonophobia (hypersensitivity to sound) or osmophobia (hypersensitivity to odours). The goal of the present study is to validate a new questionnaire made of 4 parts evaluating the presence of these 4 types of hypersensitivity, both during or between migraine attacks. It will allow to look for associations of these 4 symptoms and association of hypersensitivity with patients' or migraine's characteristics.
The purpose of the study is to assess seroprevalence of COVID-19 infection in a cohort of HIV + patients and in a cohort of patients taking PrEP by emtricitabine / tenofovir.
In last decades, several advances in the neuro-intensive management have lead to decrease mortality in Intensive Care Units. A significant morbidity remains as patients survive after a traumatic coma with uncertain quality of awakening and a high risk of functional disability. Predicting awareness recovery and functional disability of those who will awake constitutes a major challenge to inform patients' relatives, to give the best chances in terms of rehabilitation resources or to adapt intensive cares to a reasonable level. Tools currently available are not sufficient neither to predict bad awakening outcome nor to predict good functional outcome. In many countries, life's support cessation is a constant call for robust evaluation as soon as possible in ICU but it is mandatory to reach a positive predictive value of non-awaking close to 100%. Many clinical, electro-physiological, biological, radiological and functional parameters have been conducted with comatose patients assuming the purpose to predict outcome. Regarding unfavourable outcome, the gold standard is the abolition of the N20 component of somatosensory evoked potentials but the specificity is high enough only for patients with anoxic coma. Several neurophysiological markers such as MMN, P300 are correlated to a favourable outcome but the sensitivity and specificity remains low for patients who suffered a severe traumatic brain injury. New Diffusion Tensor imaging sequences provide complementary information to detect small structural lesions (diffuse axonal lesions). Recently, functional MRI analyzing Resting State has also been proposed as a prognostic marker during coma. PET using Fluoro-Desoxy-Glucose is able to assess the metabolism in key regions of the awakening network in either anaesthesia or sleep. Recent studies have reported interesting results at the chronic stage but to our knowledge, these tools have only been used to address pathophysiology's issues and never to improve coma prognosis at the initial stage. We hypothesize that the heterogeneity of the population requires a global and accurate assessment of the central nervous system, combining structural, metabolic and functional information in order to refine the prognosis. Our protocol integrates in one-sequence most radiological markers of brain injury within a unique PET-MRI in Lyon. Our most relevant originality consists in confronting FDG-PET and MRI sequences to a large clinical, electrophysiological and biological battery. The added clinical value would be to question the synergistic effect of each parameter and to find out which ones are the most useful for awakening prediction, as they have not been compared in a multi-parametric database. PET-MRI, as a new device combining physiological and prognostic questioning, allows us: - to implement a more integrative physio-pathological analysis - to avoid the cofounding effect of awareness' fluctuations in recording simultaneously multiple functional imaging techniques. The RS will be analyzed at 2 epochs in order to assess the stability of brain connectivity, related to neuronal activity (glucose metabolism) and brain perfusion. The interest of imaging result will be compared across morphological and functional sequences and in comparison, to classical marker (clinical, electrophysiological and behavioural) to build the most precise prognostic tool for acute comatose patients in ICU or diagnostic/prognostic tool for chronic patients in rehabilitation unit.
On-call work is an integral part of senior and junior patricians in a critical care department. Several studies have examined the effect of sleep deprivation on physicians on call and the impact of sleep deprivation on the quality of patient care. Some of these studies have shown that practitioners' concentration capacities have deteriorated as the guard progresses. However, few studies have looked at the physical activity of practitioners over a period of on-call time (distance covered, number of steps,...), as well as other parameters than the time spent in communication over the telephone. The age and seniority of practitioners seem to be factors that can influence these different parameters, and there are few figures in the literature.
Although outpatient surgery is increasing in France, particularly in paediatrics, compliance with analgesics prescriptions and pain management on return home remain poorly controlled parameters, although they are essential for optimal care. This is due, among other things, to parents' lack of knowledge and fears about the medicines prescribed to them. The paediatric anaesthesia unit of the Rouen University Hospital has set up a website for families to improve understanding of and compliance with the prescription of painkillers and thus improve the management of postoperative pain.
1. Inclusion of 5 families Inclusions will be made by the clinical genetics department of the Rouen University Hospital (monocentric study) and will correspond to trios of parents + child with unexplained developmental abnormalities. The inclusion of patients will be integrated in routine care and will have as immediate benefit for the included families the extensive analysis of the proband and their parents' genomes by short and long read sequencing techniques, which represent the most comprehensive diagnostic tests for developmental diseases, and which are not currently routinely available. Inclusion in clinical genetics by clinicians accustomed to prescribing genome-wide analyses will allow clear and complete information to families. Collection of consents. The trio's DNA will already be available at the molecular genetics laboratory, and a new blood sample may be proposed if necessary. Collection of sperm from the father. 2. Identification of a large set of de novo mutations. Extraction of blood DNA and sending for sequencing of the complete genome to the National Centre for Research in Human Genomics (CNRGH, Evry), in the framework of a collaboration already initiated. Analysis of the sequencing data thanks to the already existing expertise in Rouen. Identification of about 40-120 de novo mutations per trio. At this stage: interpretation of the variations identified with the secondary objective of identifying the cause of the disease in children. Long read genomes will allow to phase the de novo variants to the paternal or to the maternal haplotype. 3. Search for de novo mutations in paternal sperm samples. Extraction of spermatic DNA. Design of a sequencing panel targeting the genetic variations identified in the different trios. Preparation of the libraries, targeted high throughput sequencing at great depth thanks to the techniques and equipment already operational. Specific search for the de novo variations identified in the probands (in 2.), with for each evaluation of (i) the presence of the variation in the sperm sample, (ii) the quantity of mosaicism, reflecting the proportion of carrier spermatozoa and therefore the risk of recurrence, (iii) the presence of my variation in the blood sample of both parents in deep sequencing.
