Mortalidade atribuível às doenças cardiovasculares em adultos jovens residentes no Brasil

Introduction: cardiovascular diseases are the leading causes of death in the world. Despite the reduction in CVD incidence and mortality in the 20th century, the values remain high in the 21st century. In Brazil, there is a gap in population studies that estimated standardized mortality rates from cardiovascular diseases in young adults. Objective: to assess the trend in mortality from cardiovascular diseases in young adults, according to sex, age group and regions of Brazil. Methods: ecological time series study using official secondary data from Mortality Information Systems (SIM). All deaths from cardiovascular diseases (I00-I-99) in young adults aged 20-49 years, residing in Brazil, in the period from January 1, 2008 to December 31, 2017, were considered. Data were extracted from the Department of Informatics of the SUS (DATASUS). The Prais-Winsten regression model was used and the Annual Percentage Variation (APV) was calculated. All analyzes were performed in STATA 14.0 software. Results: during the period 2008-2017, 294,232 deaths (8.7%) from cardiovascular disease were identified in young adults aged 20-49 years. A reduction in CVD mortality was identified in all regions of Brazil, except for individuals aged 20-24 years, residing in the Northeast region, which showed an increase (APC: 2.45%) (p<0.05) 2013 -2017. The greatest variation in the mortality trend occurred in the South region (APC: -25.2%). While the smallest change in mortality trend occurred in the Northeast region (APC: -8.8%). The annual decline was smaller in the second quinquennium (2013-2017) compared to the first (2008-2012). Furthermore, the decline was more pronounced among women (APC: -2.51%) (p<0.05) 2008-2012 and in young adults aged 40-44 years (APC: -2.91%) (p<0.05) 2008-2012. Furthermore, the trend in CVD mortality stabilized from 2013 onwards in males (p>0.05). Conclusion: the results demonstrate a decreasing trend in mortality from Cardiovascular Disease in young adults in Brazil, between 2008-2017. It is concluded that there is inequality in the trend of mortality from CVD according to sex, age group and regions of Brazil.Introdução: doenças Cardiovasculares são as principais causas de morte no mundo. Apesar da redução da incidência e mortalidade por DCV no século XX, os valores permanecem elevados no século XXI. No Brasil, há lacuna de estudos populacionais que estimaram as taxas padronizadas de mortalidade por doenças cardiovasculares em adultos jovens. Objetivo: avaliar a tendência da mortalidade por doenças cardiovasculares em adultos jovens, segundo sexo, faixa etária e regiões do Brasil. Método: estudo de séries temporais com uso de dados secundários oficiais dos Sistemas de Informações sobre Mortalidade (SIM). Foram consideradas todas as mortes por doenças cardiovasculares (I00-I-99) em adultos jovens faixa etária 20-49 anos, residentes no Brasil, no período de 01 de janeiro de 2008 a 31 de dezembro de 2017. Os dados foram extraídos do Departamento de Informática do SUS (DATASUS). Foi utilizado o modelo de regressão Prais-Winsten e calculada a Variação Percentual Anual (VPA). Todas as análises foram realizadas no software STATA 14.0. Resultados: durante período 2008-2017, foram identificadas 294.232 mortes (8,7%) por doença cardiovascular em adultos jovens com idade entre 20-49 anos. Identificou-se a redução da mortalidade por DCV em todas as regiões do Brasil, exceto nos indivíduos de 20-24 anos, residentes na região Nordeste, a qual apresentou aumento (VPA: 2,45%) (p<0,05) 2013-2017. A maior variação da tendência de mortalidade ocorreu na região Sul (VPA: -25,2%). Enquanto a menor variação de tendência da mortalidade ocorreu na região Nordeste (VPA: -8,8%). O declínio anual foi menor no segundo quinquênio (2013-2017) em comparação ao primeiro (2008-2012). Além disso, o declínio foi mais acentuado entre as mulheres (VPA: -2,51%) (p<0,05) 2008-2012 e em adultos jovens com idade entre 40-44 anos (VPA: -2,91%) (p<0,05) 2008-2012. Ademais, a tendência de mortalidade por DCV se estabilizou a partir de 2013 no sexo masculino (p>0,05). Conclusão: os resultados demonstram tendência decrescente da mortalidade por Doença Cardiovascular em adultos jovens no Brasil, entre 2008-2017. Conclui-se que existe desigualdade na tendência de mortalidade por DCV segundo sexo, faixa etária e regiões do Brasil

Methodological validation of a vertical ladder with low intensity shock stimulus for resistance training in C57BL/6 mice: Effects on muscle mass and strength, body composition, and lactate plasma levels

The objective of this study was to evaluate the effects of a vertical ladder device for resistance exercises with or without electrical shock stimulus on muscle strength, body composition, limb volume, muscle fibres and plasma lactate and glycemia of female mice. This device is represented by a vertical ladder with electrostimulation. It was analysed in groups of C57BL/6 mice practicing spontaneous physical activity in enriched environment, practicing resisted climbing exercises, practicing resistance exercises with the utility model in question and controls. The acute effects of blood lactate and dark light-box behaviour, and the short-term chronic effects of muscle strength, limb volume, body composition, muscle fibre area, and central and light-dark quantification were verified. According to the findings, the vertical electrostimulation ladder model presented acute effects on lactate levels, similar to other experimental models of resistance exercise and physical activity. The behaviour in the light-dark box test showed no difference between the groups. Regarding the short-term chronic response, the best results were obtained in the impact-stimulated resistive exercise in the limb traction muscle variables, greater brown adipose tissue weight, greater quadriceps femoral muscle structure, limb and greater weight number of nuclei in the skeletal striated muscle fibres. The use of the prototype showed similarities in the acute and chronic adaptations expected in resistance training. However, new study proposals should be encouraged, as the data presented here are the first notes on the use of this utility model.We would like to thank the Foundation for Research Support of the Minas Gerais State (FAPEMIG; grant numbers: PPM-00029-17 and DEG-00010-16); National Council for Scientific and Technological Development (CNPq, grant number: 150038/2017-8 and 430759/2016-9); and the Coordination of Improvement of Higher Education Personnel (CAPES) for the support to carry out this study.

Malformações Arteriovenosa Cerebrais: uma revisão bibliográfica / Cerebral Arteriovenous Malformations: a bibliographic review

Esse estudo foi realizado com o intuito de realizar uma revisão sistemática dentro da literatura cientifica para poder melhor organizar o raciocínio clínicos quanto ao diagnóstico, tratamento e consequências de pacientes portadores de Malformações Arteriovenosa Cerebrais (MAV), uma vez que seu diagnóstico não é fácil de se realizar e a abordagem terapêutica varia de individuo em indivíduo. Contudo, entende-se que o MAV pode ser um dos diagnósticos diferenciais para tratamento de outras patologias através da apresentação da sintomatologia apresentadas pelo paciente admitidos em pronto atendimentos e que procuram clínicas de neurologia e/ou neurocirurgia para tratamento das sintomatologias mais brandas

Comparison of cognitive functions among frail and prefrail older adults: a clinical perspective

To compare cognitive function among frail and prefrail older adults. Design: Cross-sectional clinical study. Participants: Fifty-one non-institutionalized older individuals participated in this study. Measurements: Cognitive functions were evaluated through Mini-Mental State Examination (Global Cognition), Digit Span Forward (short-term memory), Digit Span Backward (working memory), Verbal Fluency Test (semantic memory/executive function). Data were compared using parametric and non-parametric bivariate tests. Binary logistic regression was used to test a frailty prediction model. Statistical significance was defined as p <= 0.01 to compare groups. In the regression model, the p value was set to be <= 0.05. Results: Statistically significant differences were observed in global cognition, and short-term memory between frail and prefrail individuals (p <= 0.01). Global cognition explained 14-19% of frailty's model. Conclusion: According to our findings, the evaluation of cognitive functions among older persons with frailty and prefrailty provides important complementary information to better manage frailty and its progression312297301COORDENAÇÃO DE APERFEIÇOAMENTO DE PESSOAL DE NÍVEL SUPERIOR - CAPESFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE MINAS GERAIS - FAPEMIGsem informaçãosem informaçã
