Seasonal variation in container productivity and infestation levels by Aedes aegypti were evaluated in two areas with distinct levels of urbanization degrees in Rio de Janeiro, a slum and a suburban neighborhood. The four most productive containers can generate up to 90% of total pupae. Large and open-mouthed containers, such as water tanks and metal drums, located outdoors were the most productive in both areas, with up to 47.49% of total Ae. aegypti pupae collected in the shaded sites in the suburban area. Water-tanks were identified as key containers in both areas during both the dry and rainy seasons. Container productivity varied according to seasons and urbanization degree. However, the mean number of pupae per house was higher in the suburban area, but not varied between seasons within each area (P > 0.05). High infestation indexes were observed for both localities, with a house index of 20.5-21.14 in the suburban and of 9.56-11.22 in the urban area. This report gives potential support to a more focused and cost-effective Ae. aegypti control in Rio de Janeiro.

Transfusion-transmitted malaria is rare, but it may produce severe problem in the safety of blood transfusion due to the lack of reliable procedure to evaluate donors potentially exposed to malaria. Here, we evaluated a new enzyme-linked immunosorbent assay malaria antibody test (ELISA malaria antibody test, DiaMed, Switzerland) to detect antibodies to Plasmodium vivax (the indigenous malaria) in the blood samples in the Republic of Korea (ROK). Blood samples of four groups were obtained and analyzed; 100 samples from P.vivax infected patients, 35 from recovery patients, 366 from normal healthy individuals, and 325 from domestic travelers of non-endemic areas residents to risky areas of ROK. P.vivax antibody levels by ELISA were then compared to the results from microscopic examination and polymerase chain reaction (PCR) test. As a result, the ELISA malaria antibody test had a clinical sensitivity of 53.0% and a clinical specificity of 94.0% for P.vivax. Twenty out of 325 domestic travelers (6.2%) were reactive and 28 cases (8.6%) were doubtful. Of the reactive and doubtful cases, only two were confirmed as acute malaria by both microscopy and PCR test. Thus we found that the ELISA malaria antibody test was insufficiently sensitive for blood screening of P.vivax in ROK.

In this study, IgA1 levels in the milk and serum of puerperae were compared and a correlation was established between the levels of this immunoglobulin and the occurrence of parasitism. Eighty-three paired milk and serum samples were obtained from puerperal and IgA1 levels were analyzed. In addition, the presence of intestinal parasites in stool samples from these puerperae was determined. Twelve puerperae tested positive for intestinal parasites and all their samples presented an IgA1 ELISA Index > 1. There was a correlation between serum and milk IgA1 levels and puerperae with any parasite in their stool (r = 0.6723; p = 0.0166). This finding may reinforce the importance of breast-feeding for the protection of neonates.

Cardiac damage is a frequent manifestation of Chagas disease, which is caused by the parasite Trypanosoma cruzi. Selenium (Se) is an essential micronutrient, the deficiency of which has been implicated in the development of cardiomyopathy. Our group has previously demonstrated that Se supplementation prevents myocardial damage during acute T. cruzi infection in mice. In this study, we analyzed the effect of Se treatment in cases of T. cruzi infection using prevention and reversion schemes. In the Se prevention scheme, mice were given Se supplements (2 ppm) starting two weeks prior to inoculation with T. cruzi(Brazil strain) and continuing until 120 days post-infection (dpi). In the Se reversion scheme, mice were treated with Se (4 ppm) for 100 days, starting at 160 dpi. Dilatation of the right ventricle was observed in the infected control group at both phases of T. cruzi infection, but it was not observed in the infected group that received Se treatment. Surviving infected mice that were submitted to the Se reversion scheme presented normal P wave values and reduced inflammation of the pericardium. These data indicate that Se treatment prevents right ventricular chamber increase and thus can be proposed as an adjuvant therapy for cardiac alterations already established by T. cruziinfection.

Leishmania spp are distributed throughout the world and different species are associated with varying degrees of disease severity. However, leishmaniasis is thought to be confined to areas of the world where its insect vectors, sandflies, are present. Phlebotomine sandflies obtain blood meals from a variety of wild and domestic animals and sometimes from humans. These vectors transmit Leishmania spp, the aetiological agent of leishmaniasis. Identification of sandfly blood meals has generally been performed using serological methods, although a few studies have used molecular procedures in artificially fed insects. In this study, cytochrome b gene (cytB) polymerase chain reaction (PCR) was performed in DNA samples isolated from 38 engorged Psychodopygus lloydi and the expected 359 bp fragment was identified from all of the samples. The amplified product was digested using restriction enzymes and analysed for restriction fragment length polymorphisms (RFLPs). We identified food sources for 23 females; 34.8% yielded a primate-specific banding profile and 26.1% and 39.1% showed banding patterns specific to birds or mixed restriction profiles (rodent/marsupial, human/bird, rodent/marsupial/human), respectively. The food sources of 15 flies could not be identified. Two female P. lloydi were determined to be infected by Leishmania using internal transcribed spacer 1 and heat shock protein 70 kDa PCR-RFLP. The two female sandflies, both of which fed on rodents/marsupials, were further characterised as infected with Leishmania (Viannia) braziliensis. These results constitute an important step towards applying methodologies based on cytB amplification as a tool for identifying the food sources of female sandflies.

Remote sensing and geographical information technologies were used to discriminate areas of high and low risk for contracting kala-azar or visceral leishmaniasis. Satellite data were digitally processed to generate maps of land cover and spectral indices, such as the normalised difference vegetation index and wetness index. To map estimated vector abundance and indoor climate data, local polynomial interpolations were used based on the weightage values. Attribute layers were prepared based on illiteracy and the unemployed proportion of the population and associated with village boundaries. Pearson's correlation coefficient was used to estimate the relationship between environmental variables and disease incidence across the study area. The cell values for each input raster in the analysis were assigned values from the evaluation scale. Simple weighting/ratings based on the degree of favourable conditions for kala-azar transmission were used for all the variables, leading to geo-environmental risk model. Variables such as, land use/land cover, vegetation conditions, surface dampness, the indoor climate, illiteracy rates and the size of the unemployed population were considered for inclusion in the geo-environmental kala-azar risk model. The risk model was stratified into areas of "risk"and "non-risk"for the disease, based on calculation of risk indices. The described approach constitutes a promising tool for microlevel kala-azar surveillance and aids in directing control efforts.

Phlebotomine sandflies are the vectors for the protozoan parasites that cause leishmaniasis. The present study investigated the species composition of sandfly fauna in the rural district of Taquaruçú, municipality of Palmas, state of Tocantins, Brazil and compared the diversity of species among intradomicile, peridomicile and forest environments during the dry and rainy seasons. Sandflies were collected using CDC light traps over the course of three months during the dry and rainy seasons. A total of 767 specimens were captured, belonging to different 32 species. The most abundant species were Micropygomyia goiana (Martins, Falcão & Silva), Sciopemyia sordellii (Shannon & Del Ponte), Evandromyia carmelinoi (Ryan Fraiha, Lainson & Shaw), Evandromyia termitophila (Martins, Falcão & Silva), Nyssomyia whitmani (Antunes & Coutinho) and Lutzomyia longipalpis (Lutz & Neiva). The highest species diversity (30) and the greatest percentage of specimens (78.3%) were obtained during the rainy season. During the dry season, the species richness and abundance were greater in domestic environments. However, during the rainy season, the forest displayed the highest species richness and the domestic environment exhibited the greatest species abundance. Several important vector species are reported in this study.

Levando em conta os vários estudos e reflexões a respeito do novo modelo de assistência ao parto e nascimento (assistência humanizada), e trabalhando como enfermeira obstétrica em um Centro de Parto Normal, surgiu o questionamento a respeito desse conceito, devido às diversas conotações dadas a esse termo. Este artigo foi produzido com a finalidade de divulgar nossa proposta de substituição da expressão "assistência humanizada ao parto", por "assistência obstétrica centrada nas necessidades da parturiente", e de discorrer como essa assistência é prestada no Centro de Parto Normal do Hospital Geral de Itapecerica da Serra (SP), que segue um protocolo de condutas obstétricas e normas preconizadas pelo Ministério da Saúde.

Inúmeros estudos têm sido realizados com a finalidade de contribuir para a prevenção do trauma perineal no parto normal. O objetivo do presente estudo foi relacionar a altura do períneo, duração do período expulsivo, variedade de posição no desprendimento cefálico, tipo de puxo, presença de circular de cordão, peso do recém-nascido e ardor na vulva ao urinar com a ocorrência de lacerações perineais. A pesquisa foi realizada em 2003, no Centro de Parto Normal do Amparo Maternal, com uma amostra de 67 parturientes sem partos vaginais anteriores. Os resultados mostraram que não houve diferença estatisticamente significante em relação às variáveis analisadas.

Este estudo objetivou identificar e comparar o traço e estado de ansiedade, no 10º dia pós-parto e estado de ansiedade no 30º dia puerperal, das nutrizes primíparas e multíparas que apresentaram indicadores de hipogalactia e nutrizes com galactia normal; verificar possíveis relações entre o estado de ansiedade das nutrizes nesses dois momentos com a presença dos indicadores de hipogalactia. É um estudo exploratório/descritivo, cujos dados foram obtidos com 168 nutrizes e seus filhos, por meio de entrevistas realizadas em consulta de enfermagem nos 10º e 30º dias pós-parto. Os resultados obtidos mostraram que as primíparas e multíparas hipogalactas e as primíparas com galactia normal apresentaram traço de ansiedade mais elevado do que os estados de ansiedade por ocasião do 10º e 30º dia pós-parto. Houve remissão dos sinais maternos de ansiedade, com o passar do tempo, que pode ter sido decorrente da correção da técnica da amamentação e apoio às nutrizes.

Investiga-se a percepção de enfermeiras obstétricas sobre sua competência na atenção ao parto normal (PN) hospitalar. Os dados foram coletados em pesquisa qualitativa, através de entrevistas individuais semi-estruturadas, realizadas em um hospital universitário de Porto Alegre, e submetidos à análise de conteúdo. A análise foi embasada nos referenciais que definem competência profissional como a capacidade de mobilizar diferentes conhecimentos, dependendo dos problemas da prática a resolver. Para as entrevistadas, a competência para atender o PN hospitalar é multidimensional, embora tenham enfatizado sua dimensão técnica. Essa ênfase é justificada pela insegurança resultante da falta de espaço para realizarem este atendimento, em função de disputas com médicos e deficiências na formação. O desejo de serem competentes no atendimento ao PN não se traduz, porém, na consciência das suas responsabilidades na transformação deste cenário. Isso sugere que, para agir nesta direção, seria necessário, não só desenvolver competência técnica, mas também ético-política.

O objetivo foi descrever os resultados maternos e perinatais da assistência no Centro de Parto Normal Casa de Maria (CPN-CM), na cidade de São Paulo. A amostra probabilística foi de 991 parturientes e seus recém-nascidos, assistidos entre 2003 e 2006. Os resultados mostraram que 92,2% das parturientes tiveram um acompanhante de sua escolha e as práticas mais utilizadas no parto foram banho de aspersão ou imersão (92,9%), amniotomia (62,6%), deambulação (47,6%), massagem de conforto (29,8%) e episiotomia (25,7%). Com relação aos recém-nascidos, 99,9% apresentaram índice de Apgar = 7 no quinto minuto; 9,3% receberam aspiração das vias aéreas superiores; nenhum necessitou ser entubado; e 1,4% foram removidos para o hospital. O modelo de assistência praticado no CPN-CM apresenta resultados maternos e perinatais esperados para mulheres com baixo risco obstétrico, sendo alternativa segura e menos intervencionista no parto normal.

Este estudo busca entender as justificativas dos trabalhadores de um Centro Obstétrico do Sul do Brasil para a utilização de práticas do parto normal consideradas prejudiciais pela Organização Mundial da Saúde. A pesquisa é do tipo exploratória, desenvolvida em julho de 2009, por meio de entrevista com 23 trabalhadores. Na análise, houve a conformação de três núcleos temáticos: Ações e condutas na dependência do trabalhador de saúde; Práticas rotineiras como facilitadoras do trabalho e Restrição da participação da parturiente no processo decisório. Algumas justificativas para o emprego das práticas: perpetuação de modelos inadequados, facilitação para a assistência no momento do parto e autoritarismo que alguns trabalhadores exercem sobre a parturiente por acreditarem serem detentores do conhecimento.

Abstract OBJECTIVE To describe the stages of construction and validation of an instrument in order to analyze the adherence to best care practices during labour and birth. METHOD Methodological research, carried out in three steps: construction of dimensions and items, face and content validity and semantic analysis of the items. RESULTS The face and content validity was carried out by 10 judges working in healthcare, teaching and research. Items with Content Validity Index (CVI) ≥ 0.9 were kept in full or undergone revisions as suggested by the judges. Semantic analysis, performed twice, indicated that there was no difficulty in understanding the items. CONCLUSION The instrument with three dimensions (organization of healthcare network to pregnancy and childbirth, evidence-based practices and work processes) followed the steps recommended in the literature, concluded with 50 items and total CVI of 0.98.
