RESUMOObjetivo: Este estudo teve como objetivo analisar as competências profissionais dos enfermeiros que atuam na estratégia saúde da família (ESF). Métodos: Utilizou-se o método de revisão integrativa, e a coleta de dados foi realizada na Biblioteca Virtual em Saúde (BVS) agregada as bases de dados LILACS, BDENF e SciELO, no ano de 2015. Resultados: Identificou-se 9 artigos, publicados nos últimos 10 anos. Discussão: Houve consenso entre os autores relacionando a capacidade do enfermeiro no desenvolvimento de competências associadas a funções diversificadas (coordenação, gerenciamento, assistência, cuidar e organização), realizadas durante o desenvolvimento de suas atividades na ESF. Para melhor entendimento as competências do enfermeiro para atuar na ESF foram organizadas em categorias: competência assistencial; competência gerencial e competência educacional. Conclusão: As competências profissionais identificadas podem oferecer subsídios para traçar diretrizes para a construção do perfil do enfermeiro que atua na ESF e sistematizar efetivamente as práticas de cuidado por esse profissional. Palavras-chave:Competência Profissional; Enfermeiros; Estratégia Saúde da Família. ABSTRACT Objective:This study aimed to analyze the professional skills of nurses working in family health strategy (ESF). Methods: We used the integrative review method, and the data collection was performed in the Virtual Health Library (VHL) aggregate the databases LILACS, and SciELO BDENF in 2015. Results: We identified 9 articles published in the last 10 years. Discussion: There was consensus among the authors relating to nurses' ability to develop skills associated with diverse functions (coordination, management, assistance, care and organization), carried out during the development of its activities in the ESF. To better understand the nurse's skills to work in the ESF were organized into categories: care competence; managerial competence and educational expertise. Conclusion: The identified professional skills can provide insight to draw guidelines for the construction of the nurse's profile engaged in the ESF and effectively systematize the practices of care for this professional.

Aedes aegypti is the principal vector of the arboviruses—yellow fever, dengue virus, chikungunya, and zika virus. Given the epidemiological importance of this mosquito, its capacity to adapt to different habitats, and its resistance to many types of control measures, systematic research into the genetic variability of the populations of this mosquito is one of the most important steps toward a better understanding of its population structure and vector competence. In this context, the present study verified the presence of distinct genetic lineages of Ae. aegypti in areas with high infestation rates, based on the analysis of microsatellite markers. The samples were collected in nine municipalities with high building infestation rates in the Mid-North region of Brazil. Six microsatellite loci were genotyped in the 138 samples, producing a total of 32 alleles, varying from one to nine alleles per locus in each of the different populations. The AMOVA revealed greater within-population genetic differentiation with high fixation rates. The general analysis of population structure, based on a Bayesian approach, revealed K = 2, with two Ae. aegypti lineages that were highly differentiated genetically. These data on the connectivity of the populations and the genetic isolation of the lineages provide important insights for the development of innovative strategies for the control of the populations of this important disease vector.
