Projeto "Animar sem quedas": reflexões sobre lazer e saúde / Project "Animar sem quedas": reflections about leisure and health

Além da prática de exercícios físicos, a participação em atividades de lazer pode contribuir com uma vida mais saudável para os indivíduos. Com o intuito de tecer reflexões acerca dessas temáticas, o objetivo deste estudo é discutir como o Projeto Animar sem Quedas tem contribuído com a vida de quem o vivencia, no sentido de identificar possíveis transformações a partir da participação neste projeto. A opção metodológica foi a técnica do grupo focal, uma técnica de pesquisa qualitativa, que obtém dados a partir de reuniões em grupo. Partindo dos resultados identificados, destacamos que, para os idosos, usufruir de boa saúde é atribuído aos benefícios que a prática de exercícios físicos lhes proporciona e que as atividades de lazer contribuem para aumentar sua autoestima, pois se sentem reinseridos na sociedade, e assim, mais felizes, valorizados e respeitados.

Besides the practice of physical exercises, participation in leisure activities can contribute to a healthier life of people. In order to make reflections about these themes, the aim of this study is to discuss how the Project Animar Sem Quedas has contributed to the lives of those who live it, in the meaning to identify possible changes from the participation in this project. The methodological option was the focal group technique, a qualitative research technique, which gets data from group meetingsThe methodological option was the focal group technique, a qualitative research technique, which gets data from group meetings. From the identified results, we emphasize that, for the elderly, enjoy good health is attributed to the benefits that physical exercise provides them and that leisure activities contribute to increase their self-esteem because they feel reintegrated in society, and so, happier, valued and respected.

Frequency of polymorphisms of genes coding for HIV-1 co-receptors CCR5 and CCR2 in a Brazilian population

Entry of human immunodeficiency type 1 virus (HIV-1) into target cells requires both CD4and one of the chemokine receptors. Viruses predominantly use one, or occasionally both, of the major co-receptors CCR5 and CXCR4, although other receptors, including CCR2B and CCR3, function as minor co-receptors. A 32-nucleotide deletion (delta32) within the beta-chemokine receptor 5 gene (CCR5) has been described in subjects who remain uninfected despite extensive exposition to HIV-1. The heterozygous genotype delays disease progression. This allele is common among Caucasians, but has not been found in people of African or Asian ancestry. A more common transition involving a valine to isoleucine switch in transmembrane domain I of CCR2B (64I), with unknown functional consequences, was found to delay disease progression but not to reduce infection risk. As the Brazilian population consists of a mixture of several ethnic groups, we decided to examine the genotype frequency of these polymorphisms in this country. There were 11.5 percent CCR5 heterozygotes among the HIV-1 infected population and 12.5 percent among uninfected individuals, similar to data from North America and Western Europe. The prevalence of CCR2-64I homozygotes and heterozygotes was 0.06 and 15.2 percent, respectively, also similar to what is known for North America and Western Europe
