Knowing the enemy: ant behavior and control in a pediatric hospital of Buenos Aires

Ant control is difficult in systems even where a variety of control strategies and compounds are allowed; in sensitive places such as hospitals, where there are often restrictions on the methods and toxicants to be applied, the challenge is even greater. Here we report the methods and results of how we faced this challenge of controlling ants in a pediatric hospital using baits. Our strategy was based on identifying the species present and analyzing their behavior. On the one hand, we evaluated outdoors in the green areas of the hospital, the relative abundance of ant genera, their food preferences and the behavioral dominances. On the other hand, control treatments were performed using separately two boron compounds added to sucrose solution which was not highly concentrated to avoid constrains due to the viscosity. Most of the species in the food preference test accepted sugary food; only one species was recorded to visit it less than the protein foods. This result was consistent with the efficacy of control treatments by sugary baits within the rooms. For species that showed good acceptance of sugar solutions in the preference test outdoors, sugar bait control indoors was 100& effective. Conversely, for the only species that foraged significantly less on sugar food, the bait treatment was ineffective. This work reveals the importance of considering the behavior and feeding preferences of the species to be controlled by toxic baits.Fil: Josens, Roxana Beatriz.

Enfermeiras americanas do Serviço Especial de Saúde Pública e a formação de recursos humanos na Enfermagem Brasileira

RESUMO Objetivo Historicizar as mudanças na formação de recursos humanos em enfermagem no Brasil, no período de 1942 a 1961, a partir da presença de 35 enfermeiras americanas designadas para trabalhar em cooperação com o SESP. Método O estudo utilizou como fontes relatórios redigidos pelas enfermeiras, que descrevem suas impressões, sugestões e atividades desenvolvidas no país, e foram analisadas a partir da análise de discurso de Michel Foucault. Resultados O período mencionado foi marcado pela presença americana nos projetos de enfermagem desenvolvidos pelo Serviço Especial de Saúde Pública (SESP). Os discursos indicaram que o período foi marcado por muitas mudanças na enfermagem brasileira, em especial no que diz respeito à captação e formação de recursos humanos para a profissão. Conclusão Pode-se afirmar que elas, através de seus discursos e influência, foram centrais para a consolidação de um novo paradigma na formação de profissionais de enfermagem no Brasil

2 nd Brazilian Consensus on Chagas Disease, 2015

Abstract Chagas disease is a neglected chronic condition with a high burden of morbidity and mortality. It has considerable psychological, social, and economic impacts. The disease represents a significant public health issue in Brazil, with different regional patterns. This document presents the evidence that resulted in the Brazilian Consensus on Chagas Disease. The objective was to review and standardize strategies for diagnosis, treatment, prevention, and control of Chagas disease in the country, based on the available scientific evidence. The consensus is based on the articulation and strategic contribution of renowned Brazilian experts with knowledge and experience on various aspects of the disease. It is the result of a close collaboration between the Brazilian Society of Tropical Medicine and the Ministry of Health. It is hoped that this document will strengthen the development of integrated actions against Chagas disease in the country, focusing on epidemiology, management, comprehensive care (including families and communities), communication, information, education, and research
