Purpose: This randomized, split-mouth, triple-blind clinical study evaluated the effect of application of nanoencapsulated eugenol (NE) on the absolute risk and intensity of tooth sensitivity (TS) resulting from in-office bleaching.Methods: Fifty-six patients received a NE in one hemiarch and a placebo gel in the other hemiarch, determined by random sequence, before in-office bleaching. A visual analogue scale (VAS) (0-10) and a numeric rating scale (NRS) (0-4) were used to record TS during bleaching and 1 and 48 h after bleaching. The tooth color was performed from baseline to 2 weeks after bleaching with shade guides (ΔSGU) and a spectrophotometer (ΔE ab , ΔE 00, and WI D ). The TS was assessed through the McNemar test (α = 0.05) and by the Wilcoxon signed-rank test (NRS) and paired t-test (VAS). The paired test-t was employed to compare the color changes (ΔSGU and ΔE ab , ΔE 00, and WI D ). The significance level was 5%.Results: No statistically significant difference was found in the absolute risk or intensity of TS between both groups (p > 0.05). A significant color change was observed in both groups (p > 0.05). Conclusion:Administration of the gel containing NE before the in-office dental bleaching did not reduce the TS and did not interfere in the bleaching effect.Clinical relevance statement: The use of desensitizing gel containing NE did not reduce in-office bleaching-induced tooth sensitivity.

Currently the Virtual Learning Environments -(AVA) are being used in the teachinglearning process Algorithms and Computer Programming -(APC) in hybrid modes. However, there is no consensus about which platforms are best suited to this purpose. Trying to answer this question, it is this work a systematic mapping databases as IEEE Xplorer and Brazilian Informatics Symposium on Education -SBIE between the years 2011 to 2016. Therefore, the objective of this study was to review the literature to some of the main tools that influence the virtual learning APC. Of the 62 preselected articles remaining 12, of which only 2 articles feature comparison between the different platforms and tools used for the APC of teachinglearning. Resumo. Atualmente os Ambientes Virtuais de Aprendizagem -(AVA) estão sendo utilizados no processo de ensino-aprendizagem de Algoritmos e Programação de Computadores -(APC), em modalidades híbridas. Entretanto, não há um consenso sobre quais plataformas são mais adequadas a esta finalidade. Tentando responder essa questão, faz-se neste trabalho um mapeamento sistemático em bases de dados como IEEE Xplorer e Simpósio Brasileiro de Informática na Educação -SBIE, entre os anos de 2011 a 2016. Assim, objetiva-se neste trabalho fazer um levantamento bibliográfico a cerca das principais ferramentas que influenciam no aprendizado virtual de APC. Do total de 62 artigos pré-selecionados, restaram 12, dos quais apenas 2 artigos apresentam comparação entre as diferentes plataformas e ferramentas usadas para o ensino-aprendizagem de APC.

This clinical trial evaluated the effect of the coadministration of ibuprofen/caffeine on bleaching-induced tooth sensitivity (TS). A triple-blind, parallel-design, randomized clinical trial was conducted on 84 patients who received ibuprofen/caffeine or placebo capsules. The drugs were administered for 48 hours, starting 1 hour before the in-office bleaching. Two bleaching sessions were performed with 35% hydrogen peroxide gel with 1-week interval. TS was recorded up to 48 hours after dental bleaching with a 0-10 visual analogic scale (VAS) and a 5-point numeric rating scale (NRS). The color was evaluated with VITA Classical and VITA Bleachedguide scales (ΔSGU) and VITA Easyshade spectrophotometer (ΔE*ab and ΔE00). The absolute risk of TS in both groups was evaluated using Fischer's exact test. Comparisons of the TS intensity (NRS and VAS data) were performed by using the Mann-Whitney test and a two-way repeated measures ANOVA, respectively. The color alteration between the groups was compared with the Student's t test. The significance level was 5%. There was no statistically significant difference between the groups for the absolute risk of TS (p = 1.00) or for the intensity of TS (p > 0.05). A bleaching of approximately 7 shade guide units was observed on the Vita Classical and Vita Bleachedguide scales, with no statistical difference between the groups. It was concluded that coadministration of ibuprofen and caffeine did not reduce the absolute risk or intensity of TS and did not interfere with the efficacy of dental bleaching.

Trata-se de um estudo transversal, realizado entre idosos fisicamente ativos participantes do Projeto de Extensão “Feliz Idade” e idosos sedentários, com o objetivo de comparar os níveis glicêmicos, de colesterol e dados antropométricos de idosos sedentários com os de idosos ativos. A coleta de dados ocorreu por meio de exame sanguíneo e antropométrico, e apontou que as variáveis colesterol total, LDL, pressão arterial sistólica, frequência cardíaca e respiratória apresentaram diferença significativa entre idosos ativos e sedentários. Concluiu-se que a prática regular de atividades físicas por idosos se mostrou significativamente benéfica nos níveis de colesterol total e LDL, na pressão arterial sistólica, e na frequência cardíaca e respiratória.

Introduction:In Brazil, AIDS has been described as a multi-faceted pandemic. This study aimed to describe the trends of AIDS in São Mateus microregion, in Espírito Santo, and in Brazil, from 1999 to 2008. Methods: Data were collected from the Notification Offences System, and a trend analysis was made. Results: Microregion-based results are close to the state and national levels but with particular features that indicate the presence of regional sub-epidemics. Conclusions: Despite progress in nearly thirty years of the epidemic, AIDS remains an incurable disease, and prevention is still the best defense against it together with the implementation of specific public policies.

O perfil da pandemia de Aids vem sendo marcado pela feminização,envelhecimento, pauperização, heterossexualização e interiorização. A microrregião São Mateus é limítrofe aos estados da Bahia e Minas Gerais, caracterizada por carência social e grande afluxo de pessoas em busca de atividades econômicas e acesso a serviços de saúde. Objetivou-se descrever a tendência da Aids segundo categoria exposta, na Microrregião São Mateus, no Espírito Santo (ES) e no Brasil, no período de 1999 a 2008. Os dados foram coletados no Sistema de Informação de Agravos e Notificações (SINAM); realizou-se análise de tendência no programa GENES. No geral, a primeira, segunda e quarta maior média de casos ocorreu na exposição heterossexual, ignorada e usuários de drogas  injetáveis, respectivamente. Por área avaliada, a transmissão homossexual foi a terceira maior no ES e Brasil e quinta maior na Microrregião; transmissão vertical (TV) terceira maior na Microrregião e sexta maior no Brasil e ES. As tendências foram crescentes em todas as categorias na Microrregião; somente nas ignoradas, usuários de drogas injetáveis e TV no ES; e ignorada e TV no Brasil. A Microrregião apresentou perfil semelhante ao estadual e nacional, mas com particularidades que apontam para a presença de subepidemias regionais.
