RESUMO
Introdução: A depressão exerce um impacto importante na qualidade de vida dos idosos, sendo imprescindível a compreensão dos fatores de risco para o desenvolvimento da doença, para que profissionais de saúde atuem no planejamento e implementação de ações direcionadas à promoção de saúde desse público. Objetivo:Analisar a prevalência de transtorno depressivo maior em idosos atendidos em um centro de referência do norte de Minas Gerais, avaliando associações com fatores de risco sociodemográficos. Material e Métodos: Realizou-se um estudo transversal e documental, a partir de 3362 prontuários de pacientes atendidos no Centro de Referência em Montes Claros, Minas Gerais, Brasil, no período entre janeiro de 2008 e dezembro de 2011. Para análise do quadro de depressão, foram utilizados dados do diagnóstico a partir do DSM-IV. Foram realizados testes de qui-quadrado e exato de Fisher para determinar fatores sociodemográficos associados àocorrência de depressão. Resultados:Odiagnóstico de transtorno depressivo maior esteve presente na maioria dos idosos (56,8%). Foi encontrada associação estatisticamente significativa na presença de transtorno depressivo maior em idosos do sexo feminino (p<0,001), não casados (p<0,001) e não alfabetizados (p<0,002). Não houve relação estatisticamente significativa entre as variáveis idade e presença de transtorno depressivo maior nos idosos estudados (p=0,599). Conclusão:Aalta prevalência do transtorno depressivo maior nos idosos desta pesquisa, bem como a identificação dos fatores associados chama atenção para necessidade de políticas de atenção voltadas para prevenção e detecção precoce do transtorno depressivo maior, de forma a atender a suas demandas e proporcionar uma longevidade com qualidade de vida.
Introduction: Depression has an important impact on thequality of life of older people. It is imperative to understand the risk factors to the development of the disease. This understanding is critical to health professionals,once they have to plan and implement actions aimed at health promotion for that population. Objective: Analyze the prevalence of major depressive disorder in older peopleattending a reference center in the North of Minas Gerais State, in order to establish associations among the disorder andsociodemographic risk factors.Material andMethods:We conducted a cross-sectionaland documentary study from 3362 records of patients treated at a Reference Center in the city of Montes Claros, Minas Gerais State, Brazil from January 2008 to December 2011. For depression condition analysis, we used the categorical classification of mental disorders (DSM-IV). We used Fisher's exact test and chi-square test to determine sociodemographic factors associated with depression.Results: The majority of older people (56.8%) were diagnosed with major depressive disorder. A statistically significant association was found between major depressive disorder and female (p <0.001), unmarried (p<0.001) and non-literate (p<0.002)older people. There was no statistically significant relation between age and the presence of major depressive disorder (p=0.599).Conclusion: The high prevalence of major depressive disorder found among older people, as well as the identification of associated factors, draws attention to the need for attention policies aimed at prevention and early detection of major depressive disorder in order to meet their demands and provide longevity with quality of life.

O objetivo desse estudo foi avaliar a adesão de meninas com idade entre 11 e 13 anos à vacina contra o papilomavírus humano no Brasil. Trata-se de um estudo retrospectivo, descritivo, transversal, com abordagem quantitativa e de caráter exploratório, utilizando-se a base de dados do Sistema de Informações do Programa Nacional de Imunizações. Em 2014, foi administrado um total de 7.436.841 doses de vacinas, a maior cobertura vacinal foi na região Sudeste e a menor na região Norte. A cobertura da primeira dose da vacina foi de 99,84%, no entanto, a cobertura vacinal da segunda dose foi de 55,65%, verificando-se redução significativa da adesão quando comparada à primeira dose. É relevante a necessidade de instituir medidas públicas e educativas, com o intuito de ampliar a cobertura da segunda dose nos próximos anos e, consequentemente, evitar a transmissão do vírus (AU).
The objective of this study was to evaluate the compliance of girls aged 11 to 13 years to the human papillomavirus vaccine in Brazil. This is a retrospective, descriptive, cross-sectional study with a quantitative and exploratory approach, using the information system database of the Brazilian Immunization Program. In 2014, a total of 7,436,841 doses of vaccines was administered, with the highest vaccination coverage in the Southeast region, and the lowest in the North region. The coverage for the first dose of the vaccine was 99.84%; however, the vaccine coverage of the second dose was 55.65%, with a significant reduction in compliance when compared to the first dose. The findings reveal the need to establish public and educational measures, in order to expand the coverage of the second dose in the coming years, and, consequently, to prevent the transmission of the virus (AU).

The mechanisms of immune response following yellow fever (YF-17DD) vaccination are still poorly understood. In this study, we have performed a longitudinal investigation (days 0, 7, 15 and 30) to characterize the cytokine profile of innate and adaptive immunity following YF-17DD first-time vaccination. Data from non-stimulated cultures demonstrated a prominent participation of the innate immunity with increased frequency of TNF-α(+) neutrophils and IFN-γ(+) NK-cells at day 7 besides TNF-α(+) monocytes at day 7, day 15 and day 30. Increased frequency of IL-10(+) monocytes was observed at day 15 and day 30, and decreased percentage of IL-4(+) NK-cells were detected at day 7, day 15 and day 30. Time-dependent and oscillating cytokine pattern was observed in CD4(+) T-cells, with low percentage of IL-12(+), IL-4(+) and IL-10(+) cells at day 7 and increased frequency of TNF-α(+) cells at day 15 besides IFN-γ(+) and IL-5(+) cells at day 15 and day 30. Later changes with increased percentage of IL-12(+) and IL-5(+)CD8(+) T-cells were observed at day 30. Increased frequency of IL-10(+) B-cells was observed at day 15, when seroconversion was detected in all vaccinees. The overall cytokine analysis of non-stimulated leukocytes showed a transient shift towards a pro-inflammatory profile at day 7, mainly due to changes in the innate immunity, which draws back toward a mixed/regulatory pattern at day 15 and day 30. The changes induced by the in vitro YF-17DD vaccine-stimulation were mainly observed at day 0 and day 7 (before seroconversion) with minor changes at day 15 and day 30 (after seroconversion). These data support the hypothesis that a complex network with mixed pro/anti-inflammatory cytokine profile is associated with the establishment of the protective immunity following YF-17DD primo-vaccination, free of adverse events.

Yellow fever (YF) vaccines (17D-204 and 17DD) are well tolerated and cause very low rates of severe adverse events (YEL-SAE), such as serious allergic reactions, neurotropic adverse diseases (YEL-AND), and viscerotropic diseases (YEL-AVD). Viral and host factors have been postulated to explain the basis of YEL-SAE. However, the mechanisms underlying the occurrence of YEL-SAE remain unknown. The present report provides a detailed immunological analysis of a 23-year-old female patient. The patient developed a suspected case of severe YEL-AVD with encephalitis, as well as with pancreatitis and myositis, following receipt of a 17D-204 YF vaccination. The patient exhibited a decreased level of expression of Fc-gammaR in monocytes (CD16, CD32, and CD64), along with increased levels of NK T cells (an increased CD3(+) CD16(+/-) CD56(+/-)/CD3(+) ratio), activated T cells (CD4(+) and CD8(+) cells), and B lymphocytes. Enhanced levels of plasmatic cytokines (interleukin-6 [IL-6], IL-17, IL-4, IL-5, and IL-10) as well as an exacerbated ex vivo intracytoplasmic cytokine pattern, mainly observed within NK cells (gamma interferon positive [IFN-gamma(+)], tumor necrosis factor alpha positive [TNF-alpha(+)], and IL-4 positive [IL-4(+)]), CD8(+) T cells (IL-4(+) and IL-5(+)), and B lymphocytes (TNF-alpha(+), IL-4(+), and IL-10(+)). The analysis of CD4(+) T cells revealed a complex profile that consisted of an increased frequency of IL-12(+) and IFN-gamma(+) cells and a decreased percentage of TNF-alpha(+), IL-4(+), and IL-5(+) cells. Depressed cytokine synthesis was observed in monocytes (TNF-alpha(+)) following the provision of antigenic stimuli in vitro. These results support the hypothesis that a strong adaptive response and abnormalities in the innate immune system may be involved in the establishment of YEL-AND and YEL-AVD.
