Processo de trabalho na estratégia de saúde da família: uma perspectiva a partir da equipe de saúde bucal

Abstract: The Family Health Strategy (FHS) have been introduced in Brazil with the purpose of reorganizing the health working process, particularly at the primary health care level, and in this restructuring movement the oral health team (OHT) has important role aiming at changing de health services. The objective of this paper was to understand the dynamics of the working process in the FHS from the perspective of the local teams and to carry out an analysis about the performance of the OHT regarding the principles of the FHS, in consonance with the Unique Health System. The researched sample was constituted of 196 health workers (dentists, dental hygiene technicians and auxiliaries of dental clinic) at the Health Units of the Municipal Health System of Curitiba. Data were collected through structured questionnaire with a response rate of 93,3%. The analysis indicated an important participation of the OHT in the Local Health Council (78,7%). Most of the dentists (79,3%) evaluated that the users of the local services have hindered access to the specialties. It is concluded that the OHT incorporated the conceptual bases and principles of the FHS in a coherent way, however there is a need for investments in the permanent education, above all about principles of multidisciplinary work; more intensive use of the epidemiology; appropriate use of tools for family approaching, besides improving the access to more complex levels of care.

The influence of nicotine in healing of small bowel anastomoses in rats: angiogenesis and miofibroblasts

Abstract: Objective: to know the effect of nicotine on angiogenesis and myofibroblast formation in anastomoses of the small bowel of rats. Methods: we randomly divided 60 Wistar rats into the groups Nicotine (N) and control (C), according to the proposed treatment. Each group was subdivided into three subgroups according to the time interval used for the evaluation (7, 14 or 28 days). The N group with 30 animals received nicotine subcutaneously at a dose of 2mg/kg body weight, diluted in 0.3ml of 0.9% saline, twice daily for 28 days prior to the operation, and for more 7, 14 or 28 days, depending on the subgroup. The C group (also 30 animals) received only saline on the same conditions and time intervals. After 28 days we carried out an end-to-end anastomosis 10cm distal to the duodenojejunal flexure in each rat. After 7, 14 or 28 days after surgery, we euthanized ten animals of each group, sent specimens of the anastomosis areas, 1cm proximal to 1cm distal, to counting of blood vessels and myofibroblasts through immunohistochemical staining by the application of monoclonal anti-factor VIII antibodies and anti-smooth muscle alpha-actin. Results: the administration of nicotine led to the decrease in the number of blood vessels measured on the 28th postoperative day and the number of myofibroblasts measured on the seventh day following completion of the anastomoses. Conclusion: administration of nicotine was deleterious on angiogenesis and myofibroblast formation in rats' small intestine anastomoses.

Análise do Sistema Nacional de Inovação no setor de energia na perspectiva das políticas públicas brasileiras

Abstract: Este articulo analiza el Sistema Nacional de Innovacion (SNI) brasileno desde la perspectiva de las politicas publicas establecidas en el Plan de Accion en Ciencia, Tecnologia e Innovacion para el sector de energia durante el periodo de 2007 a 2011, es decir, trata de responder a esta pregunta: "La politica nacional de ciencia, tecnologia e innovacion para el sector de energia ha contribuido a construir un entorno favorable a la innovacion?". El marco de referencia es la teoria del SNI. Para lograr este objetivo, se aborda el sistema nacional y sectorial de innovacion, las politicas publicas para el sector, los actores involucrados en el sistema, las acciones y las inversiones para cualificacion de personas y esfuerzos de investigacion y desarrollo (I&D), destacando las inversiones publicas y privadas. Este estudio tiene una naturaleza cualitativa, con caracter exploratorio y descriptivo y utiliza fuentes secundarias de datos, como sitios web, revistas especializadas, articulos cientificos y referencias, haciendo hincapie en articulos cientificos y datos gubernamentales disponibles en la World Wide Web. Los resultados apuntaron que el SNI se encuentra en fase de consolidacion, pero hay indicios de que este, sumado a las acciones estrategicas para el sector de energia, ha contribuido a proporcionar un entorno favorable a la innovacion.
