ABSTRACT. Distribution, abundance and diversity of Simuliidae (Diptera) in an impacted watershed in southern Brazil. This study was carried out in two areas with different degrees of environmental degradation in the Caí river basin, in Rio Grande do Sul. One sampling area is less altered and the other is strongly impaired by organic pollutants from avian and swine production. The larvae and pupae of simulids were collected using artificial substrates that remain submersed in streams for 14 days. In all sampling sites water was collected simultaneously for physical-chemical and microbiological analysis. In the less disturbed area eleven species were collected with the following frequencies: Psaroniocompsa incrustata (42.95%), P. auripellita (17.66%), Chirostilbia pertinax (16.86%), Inaequalium subclavibranchium (8.43%), I. nogueirai (5.80%), P. anamariae (3.69%), I. clavibranchium (1.58%), C. riograndense (0.92%), Lutzsimulium hirticosta (0.92%), I. botulibranchium (0.79%), Thyrsopelma itaunense (0.40%). In the more disturbed area only six species were collected: C. pertinax (84.31%), C. riograndense (7.52%), T. itaunense (4.68%), P. incrustata (2.94%), I. subclavibranchium (0.33%), Ectemnaspis dinellii (0.22%). The concentrations of nitrate and nitrite had the greatest variations and allowed us to distinguish the sampling sites by to water quality. The nitrate concentration was significatively correlated with the occurrence of C. pertinax (r 2 = 0,54; P < 0,03) and T. itaunense (r 2 = 0,55; P < 0,03) while the nitrite concentration with C. riograndense (r 2 = 0,64; P < 0,02). These data can be useful for integrated black flies control programs, currently in use in at least 170 municipalities of Rio Grande do Sul.
Introduction:Panstrongylus megistus is commonly found in wild environments of the State of Rio Grande do Sul, Brazil. The aim of this study was to characterize the network of refuges used by triatomine in a forest fragment of Porto Alegre and to identify Trypanosoma cruzi infection, associated hosts and the epidemiological importance of both hosts and triatomines. Methods: Techniques including the spool-and-line method and active searching (transects) were used to identify natural foci. Results: The food source for each triatomine was determined using the precipitin test, and the infection of marsupials was determined by xenodiagnosis. A total of 33 adults (domestic environment) and 27 nymphs (wild environment) of P. megistus were found in addition to 43 Didelphis albiventris specimens. The infection rates of triatomine adults, triatomine nymphs and opossums with T. cruzi I were 64%, 73% and 69%, respectively. Birds, rodents and opossums were the main resources used by triatomine. Conclusions: This work presents the fi rst characterization of a natural focus of P. megistus in Rio Grande do Sul. The natural characteristics of this focus and its implication in the transmission of T. cruzi are discussed.
O Programa Pesquisa para o Sistema Único de Saúde: gestão compartilhada em saúde (PPSUS) é uma iniciativa de descentralização de fomento à pesquisa em saúde para promover o desenvolvimento científico e tecnológico de cada Unidade Federativa brasileira. Este artigo tem por objetivo apresentar os principais indicadores gerenciais e a aplicabilidade para o SUS dos resultados das pesquisas financiadas pelo PPSUS no estado do Paraná. Foram analisados dados de 2004 a 2013 disponíveis na plataforma Pesquisa Saúde do Decit/SCTIE/MS. Os dados quantitativos foram analisados por meio de frequências absolutas e relativas e medidas de tendência central. Os dados qualitativos relativos à aplicabilidade dos resultados para o SUS foram categorizados, descritos e analisados seguindo o método proposto por Minayo para análise de conteúdo. O Paraná participou de cinco edições do PPSUS com 246 projetos financiados, envolvendo R$ 16.095.000,00 em recursos financeiros. As temáticas de pesquisa mais frequentes estavam relacionadas às doenças não transmissíveis (19,84%) e transmissíveis (18,62%). As pesquisas financiadas concentraram-se em Curitiba, Londrina e Maringá. A aplicabilidade dos resultados das pesquisas no SUS focou a possibilidade de disponibilizar propostas alternativas e/ou melhorias para o apoio terapêutico na assistência à saúde, gerar conhecimento para compreender o processo saúde-doença e subsidiar a formulação das políticas/programas/estratégias e a tomada de decisão. O aumento do aporte de recursos financeiros e do número de projetos de pesquisa financiados indicam a ampliação do Programa no estado e os resultados dos estudos apresentam potencial para contribuir para diversas esferas do setor saúde, da assistência à gestão.
