Efficacy of an internet-based psychological intervention for problem gambling and gambling disorder: study protocol for a randomized controlled trial
2021
Gambling Disorder is a prevalent non-substance use disorder, which contrasts with the low number of people requesting treatment. Information and Communication Technologies (ICT) could help to enhance the dissemination of evidence-based treatments and considerably reduce the costs. The current study seeks to assess the efficacy of an online psychological intervention for people suffering from gambling problems in Spain. The proposed study will be a two-arm, parallel-group, randomized controlled trial. A total of 134 participants (problem and pathological gamblers) will be randomly allocated to a waiting list control group (N = 67) or an intervention group (N = 67). The intervention program i…
ATRIAL FIBRILLATION AND MILD COGNITIVE IMPAIRMENT: WHAT CORRELATION?
2006
ATRIAL FIBRILLATION AND MILD COGNITIVE IMPAIRMENT: WHAT CORRELATION? Aim. Atrial fibrillation (AF), in addition to macroembolic complications, may also produce multiple cerebral ischemic areas due to microembolic phenomena and transient hypoperfusion, eventually leading to a progressive cognitive impairment and even to acclaimed vascular dementia. The aim of this study was to evaluate the prevalence of cognitive impairment in patients with AF. The reported results concern data obtained at the moment of recruitment. Methods. The authors studied 42 patients with a history of non valvular AF (paroxysmal, persistent, recurrent or permanent) and 40 homogenous controls in sinus rhythm without pre…
Intérêt du growth differentiation factor 15 (GDF15) comme biomarqueur pronostique après la survenue d'un Accident Vasculaire Cérébral ischémique (AVC)
2018
Introduction Le GDF15 est un biomarqueur de mauvais pronostic dans certaines pathologies cardiovasculaires comme le syndrome coronarien aigu. Son interet dans le domaine de AVC n’a ete que peu etudie a ce jour. Objectifs Notre travail consistait a l’evaluation des taux de GDF15 chez des patients hospitalises a la phase aigue d’un AVC ischemique traites par fibrinolyse et/ou thrombectomie. L’objectif principal etait d’evaluer l’association entre les taux de GDF15 et la recuperation fonctionnelle a 3 mois. Methodes Au total, 174 patients ont ete inclus entre le 16/01 et le 30/09/2017. Le consentement etait recueilli oralement. Des prelevements biologiques ont ete realises a l’admission du pat…
Impact of t-PA administration on brain BDNF levels in physiological conditions and in circulating BDNF levels in ischemic conditions : Human and anim…
2014
Our objective was to test the hypothesis that the beneficial effect of the administration of the recombinant form of tissue plasminogen activator (rt-PA) in ischemic stroke patient not only results from its fibrinolytic activity but also from its ability to increase brain-derived neurotrophic factor (BDNF) in the brain. To this end, we conducted an initial study to evaluate the effect of rt-PA on brain BDNF levels in healthy animals. In a second study, we investigated the effect of rt-PA on serum BDNF levels in ischemic stroke patients and in animals subjected to permanent focal cerebral ischemia. Blood samples were obtained from patient on admission (D0), D1, D7 and D90 after stroke and in…
O2.1. FIRST EPISODE PSYCHOSIS PATIENTS ACROSS EUROPE DIFFER IN INTELLECTUAL QUOTIENT (IQ) AND EXPOSURE TO ENVIRONMENTAL HAZARDS
2018
Abstract Background Children who later develop Schizophrenia on average are more likely to present with lower IQ; this has been considered evidence for the neurodevelopmental theory of schizophrenia. Though, recent studies have shown that first episode psychosis patients with a history of cannabis use have significantly higher premorbid and current IQ compared to those who never used it. This suggests that abnormal early neurodevelopment does not explain the aetiology of all cases of Schizophrenia, leaving space to environmental hazards. The present study aims to: investigate differences in IQ, as a marker of neurodevelopment, and in exposure to environmental risk factors in a large sample …
Specific transfer effects following variable priority dual-task training in older adults
2016
International audience; Purpose: Past divided attention training studies in older adults have suggested that variable priority training (VPT) tends to show larger improvement than fixed priority training (FPT). However, it remains unclear whether VPT leads to larger transfer effects. Methods: In this study, eighty-three older adults aged between 55 and 65 received five 1-hour sessions of VPT, FPT or of an active placebo. VPT and FPT subjects trained on a complex dual-task condition with variable stimulus timings in order to promote more flexible and self-guided strategies with regard to attentional priority devoted to the concurrent tasks. Real-time individualized feedback was provided to e…
Chicken adaptive response to low energy diet: main role of the hypothalamic lipid metabolism revealed by a phenotypic and multi-tissue transcriptomic…
2019
AbstractBackgroundProduction conditions of layer chicken can vary in terms of temperature or diet energy content compared to the controlled environment where pure-bred selection is undertaken. The aim of this study was to better understand the long-term effects of a 15%-energy depleted diet on egg-production, energy homeostasis and metabolism via a multi-tissue transcriptomic analysis. Study was designed to compare effects of the nutritional intervention in two layer chicken lines divergently selected for residual feed intake.ResultsChicken adapted to the diet in terms of production by significantly increasing their feed intake and decreasing their body weight and body fat composition, whil…
Covert digital manipulation of vocal emotion alter speakers' emotional states in a congruent direction
2016
International audience; Research has shown that people often exert control over their emotions. By modulating expressions, reappraising feelings, and redirecting attention, they can regulate their emotional experience. These findings have contributed to a blurring of the traditional boundaries between cognitive and emotional processes, and it has been suggested that emotional signals are produced in a goal-directed way and monitored for errors like other intentional actions. However, this interesting possibility has never been experimentally tested. To this end, we created a digital audio platform to covertly modify the emotional tone of participants' voices while they talked in the directi…
A Roma founder BIN1 mutation causes a novel phenotype of centronuclear myopathy with rigid spine
2018
ObjectiveTo describe a large series of BIN1 patients, in which a novel founder mutation in the Roma population of southern Spain has been identified.MethodsPatients diagnosed with centronuclear myopathy (CNM) at 5 major reference centers for neuromuscular disease in Spain (n = 53) were screened for BIN1 mutations. Clinical, histologic, radiologic, and genetic features were analyzed.ResultsEighteen patients from 13 families carried the p.Arg234Cys variant; 16 of them were homozygous for it and 2 had compound heterozygous p.Arg234Cys/p.Arg145Cys mutations. Both BIN1 variants have only been identified in Roma, causing 100% of CNM in this ethnic group in our cohort. The haplotype analysis confi…
One year of training with FES has impressive beneficial effects in a 36-year-old woman with spinal cord injury
2015
International audience; CONTEXT:Reductions of muscular and cardiorespiratory functions are often observed in people with spinal cord injury (SCI) and several studies demonstrated the benefits of aerobic and strengthening exercise training for this population. Functional Electrical Stimulation (FES) of paralyzed muscles has been proposed as a strategy to assist patients in executing functional movement but its utilization during long durations has never been investigated. The purpose of the present study was to assess the effects of a one-year training program with FES (strengthening and rowing) in one subject with SCI. Evoked torque, quadriceps muscle thickness, aerobic exercise capacity an…
