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 MR sequence called MR-ASL is used to measure cerebral perfusion in children. This ASL sequence is used with a unique post-labeling delay (PLD) due to the technical impossibility of setting different post-labeling delays. The use of a single post-labeling, chosen by the pediatric radiology department of the Necker hospital, optimal in children without arteriopathy, may not be suitable for the lengthened arterial transit time of the spins marked in the pathological carotid network of a child with arterial disease. Recently, ASL sequences with multiple delays (multi-PLD, called eASL) have been developed to overcome this limitation in arterial disease. To date, their use in the pre- and post-treatment evaluation of a child with acute or chronic arterial disease has not been evaluated. The study hypothesis is that this eASL sequence is more efficient than single-delay ASL in measuring cerebral perfusion. The study will be performed in a population of children with acute or chronic arterial disease.
Women living with HIV are unsufficiently screened for cervix cancer although they have a higher risk of developping it, resulting in many obstacles. Offering a new screening technique, more accessible and which doesn't require gynecologic examination, could help improving this coverage rate. Human Papillomavirus (HPV) screening have a higher-performance for cervix cancer than smear test. Self-collected vaginal swabs are as efficient as vaginal swabs performed by clinicians. They are also shown as acceptable among general population but only one study in South Africa has been performed on women living with HIV. In addition, recent studies on urine self-sampling for high risk HPV (HR-HPV) screening report satisfactory performance. The main hypothesis is that self-collected vaginal swabs and urine self-sampling are also acceptable among women living with HIV in the CoreVIH Ile de France Nord (CoreVIH) cohort.
BKvirus associated nephropathy (BKvAN) is a major complication in kidney transplantation. Due to BKvirus (BKv) intra-graft replication, BKvAN affects nearly 10% of patients and causes graft loss in more than 50% of cases. Without current antiviral therapy, the treatment consists of minimizing immunosuppression, secondarily exposing the patient to a graft rejection risk. Impaired BKv specific T cell response plays a crucial role in the BKvAN pathophysiology. Several teams, including ours, have demonstrated a profound impairment of BKv specific T cell response during BKvAN. Immunovirological monitoring allows an individual assessment of viral reactivation risk based on the anti-viral immune response. Our group has developed the NEPHROVIR method. This non-invasive biological method allows the identification of BKvAN risk level. The aim of this work is to evaluate, by the NEPHROVIR method, the risk to develop a BKvAN with renal impairment in kidney transplant recipients with sustained BKv viremia. The investigators propose the BK-VIR study. This is a prospective multicentric study involving 100 kidney transplant recipients with sustained BKv viremia. The aim of this work is to evaluate the NEPHROVIR method as an innovative immunovirological surveillance method for predicting the risk of BKvAN occurrence. The characterization of individual BKvAN risk level could help in the individualized follow-up and management of immunosuppression in patients. The long-term objective would be to diagnose very early, or even anticipate, the occurrence of BKvAN and to allow early readjustment of the immunosuppressive treatment.
This is a retrospective, mono centric, exploratory study to assess the incidence of a genomic alteration: NTRK gene fusion, in adult gliomas and brain metastases.
Chemotherapy-induced peripheral neuropathy (CIPN) is one of the most frequent side effects caused by antineoplastic agents, with a prevalence from 19% to over 85%. Clinically, CIPN is a mostly sensory neuropathy that may be accompanied by motor and autonomic changes of varying intensity and duration. Due to its high prevalence among cancer patients, CIPN constitutes a major problem for both cancer patients and survivors as well as for their health care providers, especially because, at the moment, there is no single effective method of preventing CIPN; moreover, the possibilities of treating this syndrome are very limited. The phycocyanin (PC), a biliprotein pigment and an important constituent of the blue-green alga Spirulina platensis, has been reported to possess significant antioxidant and radical-scavenging properties, offering protection against oxidative stress. Study hypothesis is that phycocyanin may give protection against oxaliplatin-induced neuropathy in the treatment of gastro intestinal cancers including oesogastric, colo-rectal and pancreatic cancers. This trial will be a randomised placebo-controlled study.
Bronchospasm during anaesthesia is a rare but potentially life-threatening event. They are classically part of IgE-dependent anaphylaxis but can also occur as an independent clinical entity, triggered by inflammatory factors such as smoking, chronic bronchitis, asthma, overweight and mechanical factors such as tracheal intubation. The etiological diagnosis is currently established during an allergy-anaesthesia consultation after skin testing for drugs used for induction of anaesthesia and antibiotic therapy when it is attributable. The aim of this study was to determine the characteristics that differ between 2 groups: isolated non-allergic bronchospasm and bronchospasm as part of an immediate allergic hypersensitivity reaction.
Standard treatment for oropharynx cancer is radiotherapy by intensity modulation with only one planification before treatment. Adaptative radiotherapy integrates one or several planifications during treatment radiotherapy in order to take into account anatomic modifications that occurs. Adaptative radiotherapy is very expensive, complex and is consuming human resources as well as equipment. ARTIX study (NCT01874587) entitled "Phase III trial testing the benefit of intensity-modulated radiotherapy with weekly replanifications versus intensity modulated radiotherapy with only one planification in locally advanced oropharynx carcinoma for decreasing xerostomia" is completed and clinical data from this study are used to analyse if xerostomia is decreased when adaptative radiotherapy is used. ARTOME study will assess cost-efficiency and cost utility between standard treatment (one pretherapeutic planification) and experimental treatment (weekly replanifications during treatment). Clinical data from ARTIX study will be used for ARTOME study.
The investigators wish to set up a pharmaco-epidemiological cohort within the Hospital Territorial Groups of the Cévennes-Gard Camargue, East-Hérault and Haute-Garonne and West Tarn on a specific population, patients undergoing immunotherapy for cancer, as currently there is no data available under "real life" conditions following anti-COVID vaccination19. The hypothesis is that patients undergoing immunotherapy will not develop more vaccine-related adverse events than those observed in the efficacy and safety validation studies of the BNT162b2 mRNA Covid-19, mRNA-1273 SARS CoV-2, Oxford/AstraZeneca and Ad26COV2.S, JMJ Vaccine or J & J COVID-19 Vaccine.
Cerebrovascular Accident affects the majority of the elderly population and its frequency is constantly increasing. The resulting deficits are numerous and lead in particular to an alteration in the quality of walking and autonomy. Numerous rehabilitation techniques have been described. In practice, correction instructions are often given by the therapist while the motor activity is being performed. Walking is a complex activity, as is the processing of dual-task information in elderly stroke patients. It therefore appears interesting to separate the time of motor realization and that of correction instructions. Investigators therefore propose firstly to film the patient during the performance of a walking activity and then, secondly, to analyse the video with the patient, which thus represents a source of delayed feedback. The main objective of the study is to observe the effects of this practice on walking speed. Investigators are comparing two groups of patients: the control group receiving conventional rehabilitation and the experimental group receiving conventional rehabilitation plus sessions with the video tool. They expect to observe a greater improvement in walking speed in the experimental group.
Scientific research on pruritus is in intensive development, with significant advances in understanding its pathophysiology. The causes of pruritus are very huge; they can be classified into different categories; we can find dermatological causes, systemic causes, neuropathic or neurological causes, psychogenic or even idiopathic causes. The diagnosis of psychogenic pruritus is often over stated, when no cause is found; therefore, it is important to see what is really relieving from psychic so as not to over-diagnose and adopt a therapy more in line with the real problem of the patient. In daily practice, it seems to have a tendency to separate psychogenic and neurogenic etiologies in the diagnosis of neuropathic or psychogenic pruritus. In the case of patients with psychogenic pruritus and neuropathic pruritus, no study has attempted to study the respective part of psychogenic and neurogenic components. Consequently, it would therefore be interesting to assess the areas of superposition and distinction of neuropathic and psychogenic pruritus. The aim of this pilot study is to assess the psychogenic and neurogenic components of psychogenic pruritus and neuropathic pruritus in order to improve understanding of the mechanism and therefore their management. The main objective of this study is to highlight the differences and the potential common characteristics between psychogenic and neuropathic pruritus in order to improve the differential diagnosis between these two pathologies. The secondary objective of this study is to describe the psychogenic and neurogenic characteristics of psychogenic and neuropathic pruritus.
