Abstract Background Antioxidant nutrient intake and the lesser formation of free radicals seem to contribute to chronic diseases. The aim of the present study was to evaluate the intake profile of the main dietary antioxidants in a representative sample of the adult Brazilian population and discuss the main consequences of a low intake of these micronutrients on overall health. Methods The sample comprised 2344 individuals aged 40 years or older from 150 cities and was based on a probabilistic sample from official data. The research was conducted through in-home interviews administered by a team trained for this purpose. Dietary intake information was obtained through 24-h recall. The Nutrition Data System for Research software program was used to analyze data on the intake of vitamins A, C and E, selenium and zinc, which was compared to Dietary Reference Intakes (DRIs). Differences in intake according to sex, anthropometrics, socioeconomic status and region were also evaluated. The SPSS statistical package (version 13) was used for the statistical analysis. P-values < 0.05 were considered significant. Results Higher proportions of low intake in relation to recommended values were found for vitamin E (99.7%), vitamin A (92.4%) and vitamin C (85.1%) in both genders. Intake variations were found between different regions, which may reflect cultural habits. Conclusion These results should lead to the development of public health policies that encourage educational strategies for improving the intake of micronutrients, which are essential to overall health and prevention of non-communicable diseases.

Abstract Background This article aims to discuss the incorporation of traditional time in the construction of a management scenario for pink shrimp in the Patos Lagoon estuary (RS), Brazil. To meet this objective, two procedures have been adopted; one at a conceptual level and another at a methodological level. At the conceptual level, the concept of traditional time as a form of traditional ecological knowledge (TEK) was adopted. Method At the methodological level, we conduct a wide literature review of the scientific knowledge (SK) that guides recommendations for pink shrimp management by restricting the fishing season in the Patos Lagoon estuary; in addition, we review the ethno-scientific literature which describes traditional calendars as a management base for artisanal fishers in the Patos Lagoon estuary. Results Results demonstrate that TEK and SK describe similar estuarine biological processes, but are incommensurable at a resource management level. On the other hand, the construction of a “management scenario” for pink shrimp is possible through the development of “criteria for hierarchies of validity” which arise from a productive dialog between SK and TEK. Conclusions The commensurable and the incommensurable levels reveal different basis of time-space perceptions between traditional ecological knowledge and scientific knowledge. Despite incommensurability at the management level, it is possible to establish guidelines for the construction of “management scenarios” and to support a co-management process.

Inclusive business is a term currently used to explain the organizations that aim to solve social problems with efficiency and financial sustainability by means of market mechanisms. It can be said that inclusive businesses are those targeted at generating employment and income for groups with little or no market mobility, in keeping with the standards of so-called "decent jobs" and in a self-sustaining manner, i.e., generating profit for the enterprises, and establishing relationships with typical business organizations as suppliers of products and services or in the distribution of this type of production. This article discusses the different concepts found in the scientific literature on inclusive businesses. It also analyses data from a survey conducted with the audiences of Social Corporate Responsibility seminars held by FIEMG. This analysis reveals that prospects, risks and idealizations similar to those found in inclusive business theories can also be found among individuals that run social corporate responsibility projects, even if this designation is new for them. The connection between companies and poverty, especially in relation to inclusive businesses, seems full of stumbling blocks and traps in the Brazilian context.

OBJETIVO: Avaliar a contribuição cientifica de cirurgiões da coluna brasileiros não somente em número de publicações, mas também em relação à qualidade entre Janeiro de 2000 e Dezembro de 2011. MÉTODOS: Uma pesquisa das publicações de cirurgiões da coluna brasileiros em relação à coluna ou medula espinhal foi realizada utilizando uma base de dados online; Pubmed.gov. Os resultados foram limitados para artigos publicados entre Janeiro de 2000 e Dezembro de 2011. Um total de 1.778 artigos foram encontrados após a pesquisa no Medline. Após critérios de exclusão, 206 foram selecionados. A qualidade dos periódicos foi medida através do Fator de Impacto (FI), e do Qualis CAPES e a qualidade do artigo pela classificação de Oxford. RESULTADOS: Um aumento no número de publicações de cirurgiões da coluna brasileiros foi observado. 45,1% das publicações foram nos últimos 4 anos (2008 - 2011). Estudos clínicos e relatos de caso foram os tipos de artigos mais frequentemente publicados (37,5% vs 31,1%). Um aumento no número de publicações brasileiras em periódicos não-brasileiros foi observado nos últimos anos (linear-by-linear association: 5.449, P = 0.020). A publicação Arquivos de Neuro-psiquiatria foi o periódico em que os artigos foram mais frequentemente publicados (n=67, 32%). O FI das publicações variou de 0.021 a 8.017. A análise da qualidade das publicações demonstrou que a maioria delas forneceu NE 4 (N = 113, 54.9%) ou 5 (N = 45, 21,8%). CONCLUSÃO: Houve um aumento no número e na qualidade das publicações de cirurgiões da coluna brasileiros nos últimos anos. Além disso, o número de publicações de brasileiros em periódicos não-brasileiros aumentou nos últimos anos.
