OBJETIVO: Analisar a percepção do estado de saúde dos idosos da Região Metropolitana de Belo Horizonte. MÉTODO: Utilizaram-se dados da Pesquisa por Amostra de Domicílio (PAD/MG), realizada em 2009 pela Fundação João Pinheiro. Foi examinada e entrevistada amostra probabilística de 963 pessoas com idade igual ou maior a 60 anos residentes na Região Metropolitana de Belo Horizonte. A variável dependente foi a autopercepção do estado de saúde e as variáveis independentes foram: presença de doenças que exigem acompanhamento constante, tabagismo, prática regular de atividade física, trabalho, recebimento de aposentadoria e escolaridade. Foram conduzidas análises descritivas e análises de associação estatística por meio dos testes Qui-Quadrado e T Student. RESULTADO: Dos entrevistados, 58,2% são do sexo feminino, com idade média de 69,4 anos e 44% relataram o estado de saúde como sendo "muito bom e bom", e 10,7%, "ruim ou muito ruim". Dos idosos que relataram ter problema de saúde que exigem acompanhamento constante (n = 960), 42% possuem hipertensão arterial. Da população pesquisada, 78,5% sabem ler e escrever um bilhete simples, 67,9% receberam aposentadoria ou pensão no mês de referência da pesquisa, 25% dos idosos relataram praticar atividade física regularmente. A autopercepção do estado de saúde se apresenta pior nos idosos que relataram presença de doenças crônicas, baixa escolaridade, menor ocupação laboral e redução das práticas de atividade física (P<0,05). Os resultados podem ser considerados uma ajuda na busca do desenvolvimento de ações e programas de atendimento população mineira idosa.

Auditory information is initially processed in the cochlear nuclei before being relayed to the brain. The cochlear nuclei are subdivided into dorsal, anterior ventral, and posterior ventral domains, each containing several subtypes of neurons that are thought to play discrete roles in the processing of sound. However, the ontogeny of these neurons is poorly understood, and this gap in knowledge hampers efforts to understand the basic neural circuitry of this nucleus. Here, we reveal that Bhlhb5 is expressed in both excitatory (unipolar brush cells) and inhibitory neurons (cartwheel cells) of the DCN during development. To gain genetic access to Bhlhb5-expressing neurons in the DCN, we generated a Bhlhb5::flpo knockin allele. Using an intersectional genetic strategy, we labeled cartwheel cells, thereby providing proof of concept that subpopulations of Bhlhb5-expressing neurons can be genetically targeted. Moreover, fate-mapping experiments using this allele revealed that Bhlhb5 is required for the proper development of the DCN, since mice lacking Bhlhb5 showed a dramatically diminished number of neurons, including unipolar brush and cartwheel cells. Intriguingly, the Bhlhb5::flpo allele also genetically labels numerous other regions of the nervous system that process sensory input, including the dorsal horn, the retina, and the nucleus of the lateral olfactory tract, hinting at a more general role for Bhlhb5 in the development of neurons that mediate sensory integration.

We collected acute-phase and convalescent-phase serum samples from Brazilian patients who presented with exanthem of unknown origin and evaluated these samples by means of an immunoblot assay for seroconversion to human herpesvirus 6 (HIV-6) or human herpesvirus 7 (HIV-7). Measles or rubella had been clinically diagnosed in all these patients, but their sera were negative for antibodies to both measles virus and rubella virus. Twenty percent of the patients clearly seroconverted to HHV-6 after manifestation of the exanthem, and 8% seroconverted to HHV-7. All seroconversions to HHV-6 occurred in children aged < or = 5 years; a 41% frequency of seroconversion to HHV-6 was noted among children between 3 months and 23 months of age, whereas seroconversions to HHV-7 were detected during infancy and through adulthood. Our data indicate that primary infections due to HHV-6 or HHV-7 can be misdiagnosed as measles or rubella.

The dizziness symptom was highly prevalent in the population of Minas Gerais during the assessed month of the investigation. Dizziness was prevalent in adults and the elderly and showed a statistical association with socioeconomic and demographic characteristics, as well as the assessed health status.

A última década no Brasil foi marcada por grandes investimentos no setor imobiliário, incluindo a construção de unidades habitacionais para famílias de baixa renda. A despeito do volume de investimentos, a análise dos indicadores das carências habitacionais que pautaram as políticas públicas revela uma relativa persistência do chamado déficit habitacional. A análise deste indicador no período de 2007 a 2014 mostra que, dos quatro componentes que o integram, um tem chamado a atenção pelo seu crescimento: o ônus excessivo com aluguel urbano. Com o intuito de compreender o comportamento dos componentes do déficit habitacional e, em particular do ônus excessivo com aluguel urbano, o presente artigo traz uma reflexão conceitual do indicador à luz do referencial teórico da ecologia política urbana e de uma análise comparativa entre as metodologias de cálculo do déficit habitacional em países latino-americanos. A reflexão proposta neste trabalho pretende contribuir com a revisão crítica do indicador e aprimoramento do cálculo das carências habitacionais no Brasil.Palavras–chave: déficit habitacional, ônus com aluguel, ecologia política urbana, América Latina.Abstract The last decade in Brazil was marked by substantial investments in the real state sector, including the construction of new housing units for low-income households. Despite such a significant flow of resources, an appraisal of indicators related to housing needs that have guided public policies in the sector exposes a relative persistence of the so-called housing shortage. An analysis of the housing shortage indicator between 2007 and 2014 shows that one of its four essential components, the urban rental affordability stress, was the main responsible for the observed growth tendency. In order to understand the behavior of the components of the housing shortage and, particularly, of the urban rental affordability stress, the paper brings a conceptual discussion regarding the housing shortage indicator, by means of the theoretical framework provided by urban political ecology, as well as of a comparative analysis between the different calculation methodologies for this indicator adopted by Latin American countries. The proposed debate aims to contribute to a critical review of the housing shortage indicator and the improvement of the calculation of housing needs in Brazil.Keywords: housing shortage, rental affordability stress, urban political ecology, Latin America.
