FUNDAMENTO: O papel do estresse oxidativo em pacientes idosos hipertensos com síndrome de apneia-hipopneia obstrutiva do sono (SAHOS) é desconhecido. Objetivo: O objetivo foi avaliar os níveis de Big Endotelina-1 (Big ET-1) e Óxido Nítrico (NO) em pacientes idosos hipertensos com e sem SAHOS moderada a grave. MÉTODOS: Os voluntários permaneceram internados durante 24 horas. Obtivemos os seguintes dados: índice de massa corporal (IMC), Monitorização Ambulatorial da Pressão Arterial (MAPA) - 24 horas, e medicação atual. Sangue arterial foi coletado às 7:00 h e às 19:00 h para determinar níveis plasmáticos de NO e Big ET-1. A oximetria de pulso foi realizada durante o sono. A correlação de Pearson, Spearman e análise de variância univariada foram utilizadas para a análise estatística. RESULTADOS: Foram estudados 25 sujeitos com SAHOS (grupo 1) e 12 sem SAHOS (grupo 2), com idades de 67,0 ± 6,5 anos, 67,8 ± 6,8 anos, respectivamente. Não foram observadas diferenças significativas entre os grupos em IMC; no número de horas de sono; PA diastólica e sistólica em 24 h; PA de vigília; PA no sono; ou medicamentos usados para controlar a PA. Não foram detectadas diferenças nos níveis de NO e Big ET-1 plasmáticos às 19:00 h, mas às 7:00 h os níveis de de Big ET-1 foram mais altos (p = 0,03). No grupo 1, correlação negativa também foi observada entre a saturação de oxihemoglobina arterial média e a PA sistólica - 24 horas (p = 0,03, r = -0,44), e Big ET-1 (p = 0,04, r = 0,41). CONCLUSÕES: Na comparação entre idosos hipertensos com e sem SAHOS com PA e IMC semelhantes, observou-se níveis mais elevados de Big ET-1 após o sono no grupo SAHOS. Os níveis de NO não diferiram entre os pacientes hipertensos com ou sem SAHOS.

Background:Cardiovascular diseases are the leading cause of death in Brazil. The better understanding of the spatial and temporal distribution of mortality from cardiovascular diseases in the Brazilian elderly population is essential to support more appropriate health actions for each region of the country.Objective:To describe and to compare geospatially the rates of mortality from cardiovascular disease in elderly individuals living in Brazil by gender in two 5-year periods: 1996 to 2000 and 2006 to 2010.Methods:This is an ecological study, for which rates of mortality were obtained from DATASUS and the population rates from the Brazilian Institute of Geography and Statistics (Instituto Brasileiro de Geografia e Estatística). An average mortality rate for cardiovascular disease in elderly by gender was calculated for each period. The spatial autocorrelation was evaluated by TerraView 4.2.0 through global Moran index and the formation of clusters by the index of local Moran-LISA.Results:There was an increase, in the second 5-year period, in the mortality rates in the Northeast and North regions, parallel to a decrease in the South, South-East and Midwest regions. Moreover, there was the formation of clusters with high mortality rates in the second period in Roraima among females, and in Ceará, Pernambuco and Roraima among males.Conclusion:The increase in mortality rates in the North and Northeast regions is probably related to the changing profile of mortality and improvement in the quality of information, a result of the increase in surveillance and health care measures in these regions.

Abstract Casual blood pressure measurements have been extensively questioned over the last five decades. A significant percentage of patients have different blood pressure readings when examined in the office or outside it. For this reason, a change in the paradigm of the best manner to assess blood pressure has been observed. The method that has been most widely used is the Ambulatory Blood Pressure Monitoring - ABPM. The method allows recording blood pressure measures in 24 hours and evaluating various parameters such as mean BP, pressure loads, areas under the curve, variations between daytime and nighttime, pulse pressure variability etc. Blood pressure measurements obtained by ABPM are better correlated, for example, with the risks of hypertension. The main indications for ABPM are: suspected white coat hypertension and masked hypertension, evaluation of the efficacy of the antihypertensive therapy in 24 hours, and evaluation of symptoms. There is increasing evidence that the use of ABPM has contributed to the assessment of blood pressure behaviors, establishment of diagnoses, prognosis and the efficacy of antihypertensive therapy. There is no doubt that the study of 24-hour blood pressure behavior and its variations by ABPM has brought more light and less darkness to the field, which justifies the title of this review.

Introduction: It is a big challenge that devolopes in a family with the birth ofdisabled or handycapped child. The siblings of the disabled or handicapped child aredealt with issues like sufferings, sickness, weakness and even death. Furthermorethey have to take part in assisting and care of the disabled or challenged child. Theexperience they make as they grow up with a disabled or handycapped sibling is aburden more than a challenge lies on the support service options they are entitled.The choices are from the representatives of social organisations to professional help.Aim of this work is to analyse the necessity of support services for the siblings of thedisabled or handycapped child. To achieve this, a retrospective analysis of the peoplewho were affected by such a situation is necessary.Material and Methods: Structured, guidelined, problem centered personnalinterviews with affected siblings. The method was chosen against the background ofadequate affected siblings with necessary informations, knowledge and experience.Nine interviewees were selected and requested for cooperation per e-mail. FourInterviews were done personnally and five through telephone.Result: All the interviewees had disabled or handicapped or diseased siblings. Someof the interviewees knew there was something not in order with thier sibling beforethier preschool age. Some of them noticed thier siblings as "different" through theinteractions with other schoolmates. All the interviewees except the ones who werementally challenged siblings were well informed by their parents about the situation.The limitations of the siblings were very complex. The interviewees had a lot oflimitations and obligations for themselves because of the disability of their siblings.All but one of the interviewees could atleast think of one nice experience with thiermentally or physically challenged sibling. There was also negative experiences withanxiety, anger and rag

Under greenhouse conditions cultivars Davis, IAC 73-228, PI 227.687, PI 171.451, and PI 229.358 of soybean were compared. PI 171.451 showed lower dry weight of stem in relation to Davis. Higher pod numbers produced by PI 227-687, IAC 73-228, and PI 229. 358 as compared to Davis were observed. Cultivars PI 227.687 and IAC 73-228 produced larger seed numbers. A larger weight of 100 seeds in Davis, PI 229.358, and PI 171. 45I cultivars was observed. The last two cultivars are sources of resistance against pests of soybean.
