Background Current standardized treatments for cognitive impairment in attention-deficit/hyperactivity disorder remain limited and their efficacy restricted. Transcranial direct current stimulation (tDCS) is a promising tool enhancing performance several neuropsychiatric disorders. Nevertheless, the effects of tDCS reducing patients with (ADHD) have not yet been investigated. Methods A parallel, randomized, double-blind, sham-controlled trial was conducted to examine on modulation inhibitory...
The COVID-19 pandemic, caused by the highly transmissible SARS-CoV-2 virus, has overloaded health systems in many contexts Conant and Wolfe (2008). Brazil experienced more than 345,000 deaths, as of April/2021 (2008), with dire consequences for country's public private systems. This paper aims to estimate synchronization graph between cities' contagion waves from data records. For this purpose, Motif–Synchronization method Magwire et al. (2011) was applied publicly available records...
Abstract The dynamical approach represents a new branch in the understanding of functional brain networks. Using simple indices to represent time connectivity and topological stability, we evaluated hypothesis increased stability during meditative state comparison relaxation state. We used way consider evolution synchronization patterns electroencephalography (EEG) data. time-varying graph motif method were combined build set graphs representing for 29 EEG electrodes. analysed these...
Children with cerebral palsy (CP) perform less physical activity than their typically developing peers (TDP). Pain, important comorbidity in children CP, restrains levels of activity.This study aims at exploring the influence chronic pain CP and TDP.24-hour heart rate was registered four groups children: TDP, without pain. Heart based indexes (MET percentages, energy expenditure) were computed. A self-reported diary activities rated fatigue intensity.Children reported more painful higher TDP...
Individuals with sickle cell disease (SCD) exhibit changes in static brain connectivity rest. However, little known as chronic pain associated hip osteonecrosis affects dynamic during rest and the motor imagery task. The aim of this study was to investigate characteristics functional individuals SCD secondary osteonecrosis. This is a cross-sectional comparing healthy (n = 18) 22). were stratified into high- or low-intensity groups based on intensity at time assessment. Dynamic assessed...
The aim of this study was to characterize the dynamic brain networks underlying affective modulation pleasant, unpleasant, and neutral image perception due painful stimulations in healthy subjects.Forty volunteers, 20 men women, participated study. Brain activity recorded by 64-channel electroencephalography. After data cleaning, functional were built through use motif synchronization method.We found that increased cerebral connectivity left hemisphere under pain condition broke connection...
To effectively combat the COVID-19 pandemic, countries with limited resources could only allocate intensive and non-intensive care units to a low number of regions. In this work, we evaluated actual displacement infected patients in search care, aiming understand how networks planned hospitalizations take place. assess flow outside place residence, used concepts complex networks. Our findings indicate that current distribution health facilities Bahia, Brazil, is not sufficient reduce...
Aim: Children with cerebral palsy (CP) have increased pain sensitivity and recurrent episodes; however, is underreported in children intellectual impairment. Cardiac autonomic regulation imbalanced chronic conditions neurological disorders. This study aims at exploring the autonomous nervous system of CP compared typically developing peers (TDP).Method: Heart rate variability (HRV) was recorded during 24 hours 26 TDP, examined offline baseline (sleeping, seated rest) spontaneous events. Pain...
This paper studies the association between dengue cases and climatic variables in city of São Paulo, Brazil, period from 2001 to 2011. The main hypothesis is that conditions, such as precipitation, humidity temperature, are all correlated spread Paulo. Randomization Spearman rank correlation applied over collected dataset, estimated results show only a higher temperature an increase notification new further reinforcing fact Aedes aegypti mosquito known survive distinct greatly adapting...
A doença de Alzheimer (DA) é a principal forma demência entre idosos e caracteriza-se, do ponto vista neuropatológico, pela presença emaranhados neurofibrilares deposição amiloide, que ocasiona perda da conectividade funcional em estágios pré-clínicos doença. Este trabalho visa comparar padrões topológicos (temporais espaciais) cerebral cortical indivíduos sem com DA diferentes (DA muito leve, leve moderado grave). Os dados EEG, 19 eletrodos (Sistema 10-20) foram cedidos um estudo realizado...
To effectively combat the COVID-19 pandemic, state government of Bahia, Brazil, has distributed intensive and non-intensive care units along nine regions that divide such patients could be easily hospitalized in health located at same where they live. However, observed hospitalizations networks for shows a considerable number had to travel beyond their region residence hospitalized. Hence, this study indicates current distribution is not sufficient reduce distances traveled by requiring...
