Planejamento e gestão do processo de trabalho em saúde: avanços e limites no Subsistema de Atenção à Saúde Indígena do SUS

The Indigenous Health Care Subsystem (SasiSUS), as part of the Brazilian National Health System (SUS), is responsible for health care for indigenous peoples in Brazil. At the local level, the Special Indigenous Health Districts (DSEI) are responsible for managing, planning, and organizing the work process of the multidisciplinary indigenous health teams (EMSI), which provide primary health care for this population. The objective of the study was to analyze how the planning and the management of the EMSI work process occurs. A holistic multiplecase study was carried out, considering seven DSEI as units of analysis. The main source of data used were interviews and, in a complementary way, direct observation. The results indicated that, in general, planning is present in the organization of the teams’ work process, with variations between the DSEI. Carrying out the planned actions was related to the availability of different resources: adequate functioning of the information system and the intra and intersectoral articulation of SasiSUS. As a conclusion, the need to radicalize participation in planning and management, necessary for a coordinated action to guarantee differentiated care and the principles of SUS, was pointed out.O Subsistema de Atenção à Saúde Indígena (SasiSUS), como parte do Sistema Único de Saúde (SUS), é responsável pela atenção à saúde dos povos indígenas do Brasil. Em âmbito local, são os Distritos Sanitários Especiais Indígenas (DSEI) os responsáveis pela gestão, planejamento e organização do processo de trabalho das equipes multidisciplinares de saúde indígena (EMSI), que realizam a atenção primária à saúde para essa população. O objetivo do estudo foi analisar como ocorrem o planejamento e a gestão do processo de trabalho das EMSI. Foi realizado um estudo de casos múltiplos holístico, considerando sete DSEI como unidades de análise. A principal fonte de dados utilizada foi a entrevista e, de forma complementar, a observação direta. Os resultados indicaram que, de forma geral, o planejamento está presente na organização do processo de trabalho das equipes, com variações entre os DSEI. A efetivação das ações planejadas foi relacionada à disponibilidade de diferentes recursos: funcionamento adequado do sistema de informação e a articulação intra e intersetorial do SasiSUS. Como conclusão, apontouse a necessidade de radicalização da participação no planejamento e na gestão, necessária a uma ação coordenada para garantia da atenção diferenciada e dos princípios do SUS

Instituto Oswaldo Cruz. Rio de Janeiro, RJ, BrasilNo Brasil, a área endêmica para oncocercose está restrita a Amazônia, em Terra Indígena Yanomami. O Programa Brasileiro de Eliminação da Oncocercose (PBEO) adota como principal estratégia de controle o tratamento em massa dessa população com Ivermectina, estando em consonância com o Programa para Eliminação da Oncocercose nas Américas (OEPA) e os outros cinco países endêmicos na América Latina \2013 México, Guatemala, Equador, Colômbia e Venezuela. De acordo com estratégias de monitoramento definidas pela Organização Mundial da Saúde (OMS), foi realizado esse estudo visando à disponibilização de ferramentas para avaliação do estado epidemiológico da oncocercose baseadas em análises de parâmetros entomológicos, fornecendo subsídios para medidas e as ações efetivas de controle. Foram realizadas, de 2009 a 2011, avaliações entomológicas, moleculares e epidemiológicas nos três polos base sentinelas para o PBEO \2013 Xitei (subpolo Ketaa e Watatase), Balawau (subpolo Maxapapi e Wanapiu) e Toototobi (subpolo Xiroxiropiu) para o monitoramento do impacto das estratégias de controle do PBEO/OEPA na transmissão da oncocercose no Brasil. Para análise dos parâmetros entomológicos foram realizadas capturas sistemáticas mensais de simulídeos, de 4-8 dias consecutivos de 7-18h Para análise molecular, grupos de até 50 fêmeas foram organizados de acordo com a espécie e outros parâmetros, separados em cabeças e corpos e cada grupo foi testado para a presença de DNA do parasito por PCR-ELISA. Do total de 74.397 simulídeos capturados (54% S. guianense; 40% S. incrustatum; 6% S. oyapockense), 16.971 foram coletados em Xitei/Watatase, 22.910 em Xitei/Ketaa, 2.301 em Balawaú/Maxapapi, 10.986 em Balawaú/Wanapiu e 21.229 de Toototobi. Do total de 1559 pools examinados (821 de Xitei, 302 de Balawaú e 436 de Toototobi), a prevalência estimada de S. guianense infectado foi de 1,0/2.000 simulídeos (95% LSIC \2013 2,2) no polo base Toototobi e 0,5/2.000 simulídeos (95% LSIC \2013 1,4) no polo base Balawaú. Simulim incrustatum e S. oyapockense não apresentaram nenhum pool considerado positivo. Neste estudo, o uso de diagnóstico molecular combinado com a identificação e aspectos bionômicos das espécies vetores e análises epidemiológicas possibilitou avaliar as informações sobre o estado da transmissão da oncocercose após a intervenção de 15 anos de tratamento com ivermectina. Com base nos parâmetros entomológicos de prevalência da infectividade (TI) e o potencial de transmissão anual (PTA) detectado abaixo do preconizado para as áreas sentinela foi possível verificar para período estudado a supressão da transmissão da oncocercose nas três áreas sentinela \2013 Xitei, Balawaú e ToototobiAbstract: In Brazil, the onchocerciasis endemic area is restricted to the Amazon region, in the Yanomami area. The Brazilian Program to Eliminate Onchocerciasis (PBEO) adopts as the most important strategy to control the mass treatment of this population with Ivermectina, and so does the Onchocerciasis Elimination Program for the Americas (OEPA), as well as the other five endemic countries in Latin America - Mexico, Guatemala, Equador, Colombia and Venezuela. According to the strategies defined by the World Health Organization (WHO) this study was done aiming the availability of tools for the evaluation of the epidemiological status onchocerciasis based on entomologic parameters, offering subsidies for the study and effective controlling actions. Were conducted, from 2009 to 2011, entomological, molecular and epidemiological evaluations in three sentinels areas under surveillance of PBEO \2013 Xitei (Ketaa and Watatase), Balawau (Maxapapi and Wanapiu) and Toototobi (Xiroxiropiu) to monitor the PBEO/OEPA controlling strategies impact in the onchocerciasis transmission in Brazil. To analyze the entomological parameters, monthly, simulids captures from 4-8 consecutive days, between the hours of 7am\20136pm were done. For the molecular analysis, groups of up to 50 females were organized according to species and other parameters, separated in heads and bodies and each group was tested through PCR-ELISA, for the presence of the DNA parasite From a total of 74,397 captured simulids (54% S. guianense, 40% S. incrustatum; 3% S. oyapockense); 16,971 were captured from Xitei/ Watatase, 22,910 from Xitei/Ketaa, 2,301 from Balawau/Maxapapi, 10,986 from Balawau/Wanapiu and 21,229 from Toototobi. In a total of 1,559 pools examined (821 from Xitei, 302 from Balawau and 436 from Toototobi), the estimated prevalence of infected S. guianense was 1.0/2,000 simulids (95% L SIC\20132.2) in the Toototobi area, and 0.5/2,000, simulids (95% L SIC \2013 1.4) in the Balawau area. Simulium incrustatum and S. oyapockense did not present any pool considered positive. In this study, the use of molecular diagnostic combined with the identification and bionomic aspects of the vector species, and epidemiologic analysis, assisted in the evaluation of the Onchocerciasis transmission after 15 years of Ivermectina treatment, there are presenting an updated epidemiological profile of the disease in the Brazilian Amazon. Based on entomological parameters of prevalence of infectivity (IT) and the potential for transmission (PTA) detected below levels considered the sentinel areas was verified for the period studied the suppression of onchocerciasis transmission in the three sentinel areas\2013 Xitei, Balawaú e Toototob

Detection of Onchocerca volvulus (Nematoda: Onchocercidae) infection in vectors from Amazonian Brazil following mass Mectizan distribution

Detection of Onchocerca volvulus in Simulium populations is of primary importance in the assessment of the effectiveness of onchocerciasis control programs. In Brazil, the main focus of onchocerciasis is in the Amazon region, in a Yanomami reserve. The main onchocerciasis control strategy in Brazil is the semi-annually mass distribution of the microfilaricide ivermectin. In accordance with the control strategy for the disease, polymerase chain reaction (PCR) was applied in pools of simuliids from the area to detect the helminth infection in the vectors, as recommended by the Onchocerciasis Elimination Program for the Americas and the World Health Organization. Systematic sampling was performed monthly from September 1998 to October 1999, and a total of 4942 blackflies were collected from two sites (2576 from Balawaú and 2366 from Toototobi). The molecular methodology was found to be highly sensitive and specific for the detection of infected and/or infective blackflies in pools of 50 blackflies. The results from the material collected under field conditions showed that after the sixth cycle of distribution of ivermectin, the prevalence of infected blackflies with O. volvulus had decreased from 8.6 to 0.3% in Balawaú and from 4 to 0.1% in Toototobi

Ecotopes, Natural Infection and Trophic Resources of Triatoma brasiliensis (Hemiptera, Reduviidae, Triatominae)

Triatoma brasiliensis is considered as one of the most important Chagas disease vectors in the northeastern Brazil. This species presents chromatic variations which led to descriptions of subspecies, synonymized by Lent and Wygodzinsky (1979). In order to broaden bionomic knowledge of these distinct colour patterns of T. brasiliensis, captures were performed at different sites, where the chromatic patterns were described: Caicó, Rio Grande do Norte (T. brasiliensis brasiliensis Neiva, 1911), it will be called the "brasiliensis population"; Espinosa, Minas Gerais (T. brasiliensis melanica Neiva & Lent 1941), the "melanica population" and Petrolina, Pernambuco (T. brasiliensis macromelasoma, Galvão 1956), the "macromelasoma population". A fourth chromatic pattern was collected in Juazeiro, Bahia the darker one in overall cuticle coloration, the "Juazeiro population". At the sites of Caicó, Petrolina and Juazeiro, specimens were captured in peridomiciliar ecotopes and in wilderness. In Espinosa the specimens were collected only in wilderness, even though several exhaustive captures have been performed in peridomicile at different sites of this municipality. A total of 298 specimens were captured. The average registered infection rate was 15% for "brasiliensis population" and of 6.6% for "melanica population". Specimens of "macromelasoma" and of "Juazeiro populations" did not present natural infection. Concerning trophic resources, evaluated by the precipitin test, feeding eclecticism for the different colour patterns studied was observed, with dominance of goat blood in household surroundings as well as in wildernes

Morphological Studies on the Triatoma brasiliensis Neiva, 1911 (Hemiptera, Reduviidae, Triatominae) Genital Structures and Eggs of Different Chromatic Forms

Triatoma brasiliensis is considered one of the most important Chagas disease vectors being a widespread species in semiarid areas of northeastern Brazil. The species displays distinct chromatic patterns of the cuticle in different localities. Four populations were analyzed in this study: 1-Caicó, Rio Grande do Norte, it will be called the brasiliensis population; 2-Espinosa, Minas Gerais, the melanica population; 3-Petrolina, Pernambuco, the macromelasoma population, and 4-Juazeiro, Bahia, the darker one in overall cuticle coloration, the Juazeiro population. In order to differentiate the four populations of T. brasiliensis, a comparative morphological analysis of external genital structures and of eggs were carried out. The analysis of the male genital structures evidenced minor individual structural variations that did not correlate with chromatic differences or the geographical origins, emphasizing the importance of examining sufficiently large and representative samples before using minor genital variations for taxonomic diagnosis. By scanning electron microscopy of the egg exochorion, each chromatic population presented a distinct ornamentation pattern. The melanica population differed mainly from the other populations studied since it had about 40.6%, 69.6% and 76.6% more perforations, on each cell exochorion, than the brasiliensis, the Juazeiro and the macromelasoma populations respectively. In the melanica population the perforation layout is also peculiar, with densely distributed perforations over all the egg surface. Morphometric measures of the eggs showed statistically significant differences: the macromelasoma population presented the longest length (2.43 mm) while the shortest was recorded in the brasiliensis population (2.29 mm)
