Institucionalização da Vigilância Alimentar e Nutricional no Brasil: uma breve revisão

This study aimed to conduct a literature review of the Food and Nutrition Surveillance (FNS) construction process in Brazil. The research was carried out in the first trimester of 2015, using electronic databases whose reliability level is recognized by the academic community, as well as existing records in the libraries of the School of Public Health of Minas Gerais and in the René Rachou Research Center. The descriptors used were: ‘demographic transition’, ‘epidemiological transition’, ‘nutritional transition’, ‘nutrition surveillance’, ‘food and nutrition surveillance system’, combined with ‘Brazil’, in Portuguese, published from January 1978 to March 2015. Out of the 270 works found, only 52 were selected for detailed analysis: 14 of them addressed the “Legal and historical milestones of food surveillance”; 24 focused on “System of Food and Nutrition Surveillance System”; 23 addressed to “Nutritional Deviations”, and 12 discussed “Demographic, Epidemiological and/or Nutritional Transition”. The present review described the process of construction of FNS, taking into account the attempts of deployment of different information systems in some Brazilian states; the strategies used to disseminate and increase the scope of the proposed systems; the difficulties faced by professionals and managers, accompanied by the current drawbacks and challenges for implementation of food surveillance all over Brazil.Este trabalho se propôs a fazer uma revisão da literatura que contempla o processo de construção da Vigilância Alimentar (VAN) no Brasil. O estudo foi realizado no primeiro trimestre de 2015, utilizando as bases de dados eletrônicas com nível de confiabilidade reconhecido pelo meio científico, somadas aos registros existentes nas bibliotecas da Escola de Saúde Pública de Minas Gerais e do Centro de Pesquisas René Rachou. Foram utilizados os descritores ‘transição demográfica’, ‘transição epidemiológica’, ‘transição nutricional’, ‘vigilância nutricional’, ‘sistema de vigilância alimentar e nutricional’ em associação ao termo ‘Brasil’, em português, no período de janeiro 1978 a março de 2015. Dos 270 trabalhos encontrados, apenas 52 permaneceram para análise detalhada, sendo que 14 abordavam a temática “Marcos legais e históricos da VAN”; 24, o “Sistema de Vigilância Alimentar e Nutricional”; 23 abordavam os “Desvios Nutricionais”; e 12, a “Transição Demográfica, Epidemiológica e/ou Nutricional”. Descreveu-se o processo de construção da VAN no Brasil, contemplando: as tentativas de implantação de diferentes sistemas de informação em alguns estados brasileiros; as estratégias utilizadas para dar visibilidade e elevar a cobertura dos sistemas propostos; as dificuldades enfrentadas pelos profissionais e gestores, apresentando os entraves e desafios atuais para realização da Vigilância Alimentar no território nacional

Biological aspects of crosses between Triatoma maculata (Erichson, 1848) and Triatoma pseudomaculata Corrêa & Espínola, 1964 (Hemiptera: Reduviidae)

Due to morphological similarities between Triatoma maculata and T. pseudomaculata, which comprise the "maculate complex", both had been regarded as the same species until 1964. Considering that the studies on triatomine hybridization permit hypotheses formulation concerning origin and divergence of species, enabling a quantitative analysis of taxonomic relationships between species, the present investigation was aimed at broadening further understanding related to the capacity of hybrid production by determining the degree of reproductive isolation between T. maculata and T. pseudomaculata. Our results have demonstrated that T. maculata and T. pseudomaculata showed no differences regarding reproduction patterns and they are able to cross, generating infertile hybrids
