tDCS is a technique emerging as a prospective therapy for neurologic, psychiatric and addictive disorders. Specifically, fronto-temporal tDCS, with anodal stimulation over the left dorsolateral prefrontal cortex (DLPFC) and cathodal stimulation over the left temporo-parietal junction (TPJ), has been reported to reduce treatment-resistant auditory hallucinations (AH), negative symptoms and insight of the illness in schizophrenia. However, despite an increasing use in clinical settings, tDCS suffers from limitations, especially regarding the strength and the duration of therapeutic effects. Some imaging reports suggest that tDCS effects are not restricted to the brain areas located under the electrodes, but spread through distributed cortical networks functionally connected with the targets and reach subcortical areas. Overall, these studies suggest that tDCS modulates functional connectivity within and across resting-state networks and brain activity. However, these effects are currently described at different levels depending on the imaging technique used. Moreover, the majority of studies have focused on motor cortex stimulation, while the specific effects of fronto-temporal tDCS are scarce. Finally, effects of the stimulation applied online are rarely inspected. According to the therapeutic effects of fronto-temporal tDCS on schizophrenia and the dopaminergic pathophysiological hypothesis of schizophrenia, the effect of fronto-temporal tDCS on dopaminergic transmission is of major interest. As the cortex is densely connected with basal ganglia areas, tDCS effects are probably capable to reach subcortical dopaminergic areas. Indeed, recent fMRI studies highlighted subcortical effects of tDCS applied at the cortical level including modulations of cortico-striatal and thalamo-cortical functional connectivity. In addition, some studies suggest that cortical stimulation by other approaches, such as transcranial magnetic stimulation (rTMS) modulates dopaminergic transmission. However, tDCS effects on dopaminergic transmission have been investigated only indirectly. Finally, information about biological effects of tDCS is scattered and creating a coherent ensemble is a mandatory and critical step to understand the mechanisms of action of tDCS. According to the hypothesis that fronto-temporal tDCS modulates brain activity, connectivity and dopaminergic transmission, the aim of this project is to reveal the combined neurobiological impact of an online single session of fronto-temporal tDCS in a unique experiment by developing a simultaneous multimodal imaging approach (PET-MRI). The online implementation of the stimulation will allow deciphering changes induced during and after stimulation. As a first step before investigating patients with schizophrenia, healthy subjects will be involved in the present study. The distributed changes will be explored at rest through: - Spontaneous functional connectivity assessed by functional magnetic resonance imagery (fMRI). - Brain activity assessed by cerebral blood flow quantitatively and directly measured by arterial spin labelling (ASL). - Connectivity assessed by diffusion tensor imaging (DTI). - Specific and localized dopaminergic transmission evaluated by positron emission tomography (PET) using dopaminergic D2 subtype receptor availability via [11C]raclopride binding. The pioneering aspects of the project are to use an innovative simultaneous multimodal imaging system, adopt the tDCS montage used in our validated therapeutic context and apply tDCS online. We expect that our unique approach will provide an imaging biomarker essential to improve our understanding of: 1. the "normal brain" and further deficient mechanisms underlying schizophrenia as well as neurological disorders. 2. neurobiological effects of tDCS in order to: - Bring key element of the proof of concept of tDCS - Optimize tDCS in a therapeutic context - Suggest a marker of the therapeutic response
The primary purpose of this study was to assess the noninferiority of ravulizumab compared to eculizumab in adult participants with PNH who were clinically stable after having been treated with eculizumab for at least 6 months.
This study evaluates the link between genetic polymorphisms as r7903146, rs12255372 of TCF7L2 gene and the risk of developing hyperglycemia during Intensive care unit stay
The nociceptif system of the newborn child is functional from 22 to 23 weeks of pregnancy. During the delivery the baby is exposed to multiple exterior factors and he is capable to memorize the pain .Recent epidemiologic studies showed that the coverage of pain was insuffcient and also an increase of analgesic means. Normally the pain coverage have to be managed and group every painful gesture. In fact all these recommandations are not followed by medical team. The aim of the study is to evaluate the prevalence of this type of pain as to set up an adequate coverage.
Post-thrombotic syndrome (PTS) is a frequent and burdensome complication of deep-vein thrombosis (DVT). In the absence of curative treatment of established PTS, its management is based on the prevention of its occurrence thanks to anticoagulants and compression stockings. So far, predictors of disabling PTS are unknown precluding from optimally selecting patients for invasive (early thrombus removal) or innovative/expensive treatments. In addition, little is known on the incidence of PTS in the very long-term. Objectives: To assess, 12 years after a symptomatic venous thromboembolic (VTE) event, Primary objective: incidence and severity of PTS after a lower limb DVT. Main Secondary objectives: 1. Incidence and severity of PTS according to VTE initial presentation (isolated distal DVT, isolated proximal DVT, PE + DVT). 2. Incidence and risk factors of disabling PTS Methods: Very long-term follow-up (12 years) of patients recruited in the large, multicentre, prospective, observational OPTIMEV study for a suspicion of VTE confirmed or ruled out with objective tests (Clinical Trials NCT00670540). All patients with a DVT, an isolated PE and a random selection of controls (VTE - patients without any history of VTE after the 3 years of follow-up) will first benefit from a phone-PTS assessment. Those patients presenting at least a mild venous insufficiency and a selection of controls will undergo a clinical follow-up visit with clinical and Compleat Ultra Sound (CUS) assessment of PTS/venous insufficiency and an assessment of quality of life. Perspectives: Improving our knowledge of PTS' incidence and predictors and of the impact of usual treatment. Better selecting patients eligible for invasive/innovative/expensive preventative procedures.
