RESUMO Este estudo investigou a relação entre suporte social, características sociodemográficas, clínicas e adesão ao Tratamento Antirretroviral (TARV) utilizando o questionário Social Support Inventory for People who are HIV Positive or Have AIDS. Para isso, foram avaliados 119 usuários HIV-positivos - dos quais 53,8% eram homens. Em relação à disponibilidade e satisfação, os valores médios foram de 3,37 (DP=1,00) para o suporte instrumental e 3,48 (DP=1,06) para o suporte emocional. Observaram-se diferenças significativas na disponibilidade e satisfação do suporte social com variáveis sociodemográficas e clínicas. Verificou-se que, quanto maior a disponibilidade e a satisfação com o suporte social, maior o OR para a adesão ao tratamento. O desenvolvimento de estratégias de apoio social pode contribuir positivamente para o controle da doença e melhor qualidade de vida dos usuários.

RESUMO:Foram analisadas sementes de castanhas-do-pará sem casca adquiridas a granel no comércio varejista de Curitiba. Os teores de umidade, lipídios e minerais foram determinados de acordo com a metodologia proposta pelo Instituto Adolfo Lutz. O teor de carboidratos foi obtido por diferença. As quantidades de proteínas, fibra alimentar, selênio e aflatoxinas totais foram determinadas segundo metodologia da Association of Official Analytical Chemists. As determinações analíticas mostraram que 100g de sementes de castanha-do-pará contêm elevado valor calórico (691 kcal), 14,28g ± 0,08 de proteínas, 67,52g ± 0,45 de lipídeos, 6,56g de carboidratos, 3,64g de fibra alimentar, 3,65g ± 0,03 de minerais e 0,425mg de selênio. O teor de aflatoxinas totais inferior a 1,00µg/kg indicou a segurança da amostra em relação a este metabólito tóxico. A ingestão diária recomendada de selênio é de 0,034mg; 7g da amostra de castanha-do-pará (2 unidades) correspondem a 87,65% das necessidades diárias Palavras chaves: Composição nutricional, Bertholletia excelsa Bonpl., Selênio, Aflatoxinas ABSTRACT:Shelled Brazil nuts purchased in retail stores in Curitiba were analysed. The moisture, total fat and ash were determined according to the methodology proposed by Adolfo Lutz Institute. The carbohydrate content was performed by diference. The amounts of proteins, dietary fiber, selenium and total aflatoxins were determined according to the methodology of Association of Official Analytical Chemists. The analysis showed that 100g of this product contain high caloric value (691 kcal), 14,28g ± 0,08 of proteins, 67,52g ± 0,45 of total fat, 6,56g of carbohydrates, 3,64g of dietary fiber, 3,65g ± 0,03 of ash, 0,425mg of selenium. The total aflatoxins value lower than 1,00µg/kg indicated the safety of this sample relative to this toxic metabolite. The recommended daily intake of selenium is 0,034mg; 7g of Brazil nut (2 units) provide 87,65% of the daily needs.

Context: Hepatitis E virus (HEV) is well-known to be transmitted by the fecal-oral route. In addition, several studies in Europe and Asia had reported potential HEV transmission associated with blood transfusion, but this route is still uncertain.Objective: The aim of this study was to estimate the anti-HEV IgG seroprevalence among blood donors around the world using the Bayesian-based methods.Evidence Acquisition: A systematic review was performed using the PubMed/Medline, Scopus, Web of Science and Cochrane Library databases using the terms "prevalence", "hepatitis E" and "blood donors". Studies with a timeframe from inception to March 2016, in Roman characters, that had outcomes of interest such as prevalence of IgG antibodies were included. The estimation of anti-HEV IgG (presented as the event rate and 95% confidence intervals, CI) was performed using a Bayesian-based random effect model using the Comprehensive Meta-Analysis software, version 2. Pairwise meta-analyses and chi-square tests were used to assess significant differences between different sexes and ages. Results and Conclusions:Of the retrieved studies, 71 met the inclusion criteria, comprising a total of 113 316 blood donors. The prevalence rate was statistically significant in males and over 40 years old donors (P < 0.05). The overall estimation of the anti-HEV IgG prevalence was 0.058 (CI 95%: 0.049 -0.068). Subgrouping by region, the estimates were higher for Asia and the Middle East, respectively: 0.113 (CI 95%: 0.040 -0.278) and 0.112 (CI 95%: 0.081 -0.152). Europe, Africa, Oceania and America had an estimated prevalence between 0.014and 0.088. A relevant prevalence of anti-HEV IgG among blood donors was found worldwide, especially in Asia and the Middle East and in males and donors over 40 years. This review reinforces the view that HEV parenteral route infection needs to be further investigated and possibly screened for in transfused blood.
