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.
Impact of attention on obsessive through the THOUGHT-scale (Troublesome Human Obsessions and Untargeted General Habitual Thoughts Scale): a description of the content of thoughts according to the level of attention demanded by the environment in patients with obsessive disorder compulsive disorder (OCD) and patients without OCD" Validation of THOUGHTS.
Several studies have demonstrated that vitamin D deficiency at birth is a risk factor of bronchopulmonary dysplasia. However, in an animal model of bronchopulmonary dysplasia vitamin D overdose has also been associated with an increased mortality and an increased lung injury. Such vitamin D overdose has been frequently reported in hospitalized neonates receiving the current supplementation. The hypothesis is that vitamin D overdose is an independent risk factor of bronchopulmonary dysplasia or death among infants born below 31 weeks gestational age excluding infants with vitamin D deficiency. This retrospective cohort study will include all infants born before 31 weeks of gestation (WG), who were hospitalized in a tertiary neonatal intensive care unit (NICU) during at least 10 days, for who at least one 25OH vitamin D determination was performed before 36 WG corrected age and whose parents are not opposed to the study. A descriptive analysis of the cohort depending on the occurrence of vitamin D overdose will be performed. A multivariate analysis will determine if vitamin D overdose is an independent risk factor of bronchopulmonary dysplasia or death among preterm infants, adjusting on the covariates known to be associated with bronchopulmonary dysplasia.
PLATA aims to develop an algorithm to identify vocal biomarkers of Alzheimer's dementia. Using data collected as part of routine care, speech patterns will be compared to known biomarkers of Alzheimer's disease, such as amyloid 1-42 and p-Tau in CSF (cerebrospinal fluid). If biomarkers of speech can be identified in Alzheimer's disease, it is possible that patients and research participants will no longer need to undergo need to undergo the intensive and invasive baseline biomarker methods currently used, such as lumbar punctures and PET scans.
Follow-up of patients with complex congenital heart disease (CHD) usually involves ultrasound imaging or even MRI or CT scans of the heart and stress testing. But these examinations can be challenged in terms of their sensitivity. Thus, the development of non-invasive jugular venous and radial arterial pressure sensors, reflecting the hemodynamic function of the right heart, would be very useful to the clinician responsible for early detection of a deficit in right ventricular function.
The patient is randomized to one of the following groups: - Experimental group: Radiotherapy in painting dose on histoscannographic mapping - Control group: standard pan-sinus radiotherapy
Time processing is fundamental to survival and goal reaching in humans. Different time scales (seconds, minutes, and beyond) are processed through specific cognitive processes involving different neural representations. It is generally agreed that time scale in seconds-to-minutes range named "interval timing" would be anatomically linked to the striatum. Indeed, it is possible to demonstrate a deficit of interval timing processes in patients suffering from striatal damage (Huntington's disease). However, recent findings show involvement of a second brain structure, the hippocampus, in interval timing processing in the minutes range, suggesting an interaction between the striatum and hippocampus. Presumably, patients with hippocampal damage (Alzheimer's disease) would specifically show a decrease in performance for this minutes-range time scale. This study aims to provide a better understanding of the role of the striatum in the treatment of time and its interactions with other brain structures such as the hippocampus. More specifically, it is unclear whether the striatum plays a platform role that would always be involved regardless of the time scale, as suggested by the unified model of time or whether different brain structures is solicited according to the time scale, as suggested by the modular system model. In order to elucidate these issues, a potential double dissociation between brain structures and time scales will be tested.
The PROFA study is an international, multi-centric observational and validation study to assess the patient-reported, psychosocial and economic outcomes of patients with Friedreich Ataxia (FA). Eligible patients will be recruited from six study centers in Germany, Austria and France. Patients will complete a baseline assessment via face-to-face interviews at the study centers and multiple momentary follow-up assessments via a mobile-health app at home daily to monthly for six months. Study results will gain essential and in-depth insights into the daily life of patients with FA.
Hypnosis is a technique allowing the patient to focus his mental attention on a thought or a sensation, with the aim of reducing or modulating the intensity of a negative feeling or an ordeal encountered during the course of treatment. This tool can be used when patients are faced with chronic disorders (pain, anxiety, ...) or iatrogenic effects (nausea, asthenia, ...). The patient is referred to hypnosis care by the doctor, psychologist or paramedics who follow him, when they detect a need. Several scientific studies have shown the effectiveness of hypnosis in improving the quality of life of patients with breast cancer and in reducing pain during invasive procedures. On the other hand, in hematology, no research has measured the evolution of anxiety, over time, in patients receiving hypnotherapy.
Immune-checkpoint inhibitors (ICIs) have radically changed the therapy of cancer in recent years. ICIs promote antitumor immune response inhibiting one of the following immune checkpoints: cytotoxic T-lymphocyte antigen-4 (CTLA-4; ipilimumab), programmed death-1 (PD-1: pembrolizumab, nivolumab, and cemiplimab), and programmed death ligand-1 (PD-L1: atezolizumab, durvalumab, and avelumab). Despite the desired effect as cancer treatment, ICIs can break immune tolerance to self-antigens and induce specific toxicities known as immune-related adverse events (irAEs), that may affect both peripheral and central nervous system (Neurological immune mediated adverse events, NirAEs). The pathogenic mechanisms underlying NirAEs are probably heterogeneous, as reflected by the variety of clinical phenotypes and severity. NirAEs are rare, but there is some concern that the incidence may increase in the next future, in particular because ICIs are being used more and more for cancers commonly associated with paraneoplastic neurological syndromes (e.g. small-cell lung cancer). Moreover, NirAEs are usually severe, and often fatal. Indeed, irAEs-related complications are the most common cause of death among these patients. On the other hand, these patients usually have a good tumor response to immunotherapy. There is some evidence that irAEs may predict ICIs efficacy and consequently NirAE surivors are likely to have longer life expectancy than non-NirAE patients. Therefore, it is of utmost importance to better characterize the long-term outcomes of NirAE patients in terms of neurologic disability and mortality, and to identify predictors of severe NirAEs. So far, only few studies with sufficient follow-up have been published on the topic, and they included only small number of patients. The aims of our study is to characterize the main clinical and paraclinical features of NirAEs in a large cohort of NirAE patients, to assess long-term outcomes and to identify prognostic factors. This study will help define new guidelines regarding NirAE prediction and management.
Hyponatremia is a frequent complication of subarachnoid hemorrhage (SAH) with a prevalence of 30 to 50% in patients with this condition. This hydro-electrolytic disorder is responsible for an increase in morbidity with the appearance of neurological disorders. Also, it has been shown that there are ionic changes in the cerebrospinal fluid and a probable alteration of the blood-brain barrier in patients with SAH. The kinetics and relationship between hyponatremia and these changes remain unknown. The main objective of the study is to determine whether the change in cerebrospinal fluid (CSF) composition, precedes the development of hyponatremia. For this, the investigators propose to study the evolution of the CSF ionogram with the blood ionogram. Furthermore, they will perform additional analyses on the basis of a control group (CSF of patient with normal pressure hydrocephalus) to determine the effect of SAH on ionic changes. The hypothesis of the study is that there is a correlation between the change in CSF blood ionogram and the development of hyponatremia between day 0 and day 14.
