What we need to know about exercise, neurodegenerative disease and ageing? A Systematic Review.

As doenças neurode-generativas são caracterizadas por um conjunto de patologias crónicas e irreversíveis do sistema nervoso. Até ao momento não foram realizadas revisões de literatura que relacionem o exercício, as doença neurodegenerativas e o envelhecimento. Assim, o objetivo desta revisão sistemática foi analisar a literatura actual sobre os efeitos e associações entre o exercício físico em quatro doenças neurodegenerativas: Alzheimer, Parkinson, Huntington e Demência Vascular.Neurodegenerative diseases are characterized by a set of chronic and irreversible pathologies of the nervous system. As well as know, no literature reviews have been conducted to link exercise, neurodegenerative disease and ageing. Therefore, the aim of this systematic review was to analyse the current literature about the effects and associations amongst exercise on four neurodegenerative diseases: Alzheimer, Parkinson, Huntington and Vascular Dementia.info:eu-repo/semantics/publishedVersio

Acute exercise improves cognition in the depressed elderly: the effect of dual-tasks

OBJECTIVE: The goal of this study was to assess the acute effect of physical exercise on the cognitive function of depressed elderly patients in a dual-task experiment. INTRODUCTION: Physical exercise has a positive effect on the brain and may even act as a treatment for major depressive disorder. However, the effects of acute cardiovascular exercise on cognitive function during and after one session of aerobic training in elderly depressive patients are not known. METHODS: Ten elderly subjects diagnosed with major depressive disorder performed neuropsychological tests during and after a moderate physical exercise session (65-75%HRmax). A Digit Span Test (Forward and Backward) and a Stroop Color-Word Test were used to assess cognitive function. The elderly participants walked on an electric treadmill for 30 minutes and underwent the same cognitive testing before, during, immediately after, and 15 minutes after the exercise session. In the control session, the same cognitive testing was conducted, but without exercise training. RESULTS: The results of the Digit Span Test did not change between the control and the exercise sessions. The results of the Stroop Color-Word Test improved after physical exercise, indicating a positive effect of exercise on cognition. CONCLUSIONS: These data suggest that the cognitive functions of depressed elderly persons, especially attention and inhibitory control, are not impaired during and after an acute session of physical exercise. In contrast, the effect of dual-tasks showed beneficial results for these subjects, mainly after exercise. The dual-task may be a safe and useful tool for assessing cognitive function

Sono, estresse, fadiga e funcionamento executivo do Policial Rodoviário Federal no Rio Grande do Sul.

Brazil is among the top 10 countries with the highest number of deaths from road traffic accidents. Within this scenario are the Federal Highway Police (FHP), who carry out overt patrols, seeking to ensure public safety and preservation of life. A cross-sectional observational study with an analytical descriptive approach was conducted, investigating the sleep quality, stress, fatigue, and executive functioning of these professionals, aimed at updating the institutional health intervention guidelines. We identified a prevalence of individuals with impaired sleep quality, and the presence of chronic fatigue and vulnerability to work stress, in infrastructure and routine (EVENT test). This factor relates to issues such as of working double shifts, health problems and accidents at work.  O Brasil está entre os 10 países com maior número de óbitos por acidentes de trânsito. Esse problema diz respeito ao cenário em que atuam os Policiais Rodoviários Federais (PRFs), os quais realizam patrulhamento ostensivo visando à segurança e à preservação da vida. Com o objetivo de atualizar diretrizes institucionais de intervenção em saúde para esses profissionais, passamos a investigar qualidade do sono, estresse, fadiga e funcionamento executivo, utilizando como delineamento um estudo observacional do tipo transversal com abordagem descritiva analítica. Identificamos prevalência de profissionais com comprometimento na qualidade do sono, e presença de fadiga crônica e de vulnerabilidade ao estresse no trabalho, no item infraestrutura e rotina (teste EVENT). Esse fator está relacionado a questões como dobrar jornada de trabalho, problemas de saúde e acidentes de trabalho.

Educomunicação e suas áreas de intervenção: Novos paradigmas para o diálogo intercultural

oai:omp.abpeducom.org.br:publicationFormat/1O material aqui divulgado representa, em essência, a contribuição do VII Encontro Brasileiro de Educomunicação ao V Global MIL Week, da UNESCO, ocorrido na ECA/USP, entre 3 e 5 de novembro de 2016. Estamos diante de um conjunto de 104 papers executivos, com uma média de entre 7 e 10 páginas, cada um. Com este rico e abundante material, chegamos ao sétimo e-book publicado pela ABPEducom, em seus seis primeiros anos de existência. A especificidade desta obra é a de trazer as “Áreas de Intervenção” do campo da Educomunicação, colocando-as a serviço de uma meta essencial ao agir educomunicativo: o diálogo intercultural, trabalhado na linha do tema geral do evento internacional: Media and Information Literacy: New Paradigms for Intercultural Dialogue
