Necessidade de aprimoramento do atendimento à saúde no sistema carcerário

OBJETIVO Analisar a estrutura física, as condições de trabalho dos profissionais da saúde e o delineamento de processos estabelecidos em unidades prisionais. MÉTODOS Foram analisados 34 centros de detenção provisória e 69 unidades prisionais masculinas e seis femininas do Estado de São Paulo, Brasil, em 2009. Foi desenvolvido instrumento autoaplicativo para coleta de dados quantitativos sobre as características de estrutura, equipamento e pessoal para atendimento à saúde nas unidades prisionais. A análise de variância (ANOVA) ou equivalente não paramétrico e os testes de Qui-quadrado ou Fisher foram utilizados para comparação de variáveis contínuas ou categóricas, respectivamente, entre os grupos estudados. RESULTADOS Os principais problemas foram o retardo nos resultados de exames laboratoriais e de imagem. Quanto às equipes, grande maioria apresentou condições próximas da proposta pela Comissão InterGestores Bipartite 2013, mas sem que isso se refletisse em melhoria dos indicadores. Com relação ao processo, observou-se que mais de 60,0% das unidades prisionais estão localizadas em cidades pequenas, sem condições estruturais de saúde para garantir o atendimento secundário ou terciário para continuidade do processo de tratamento. CONCLUSÕES O perfil apresentado das unidades prisionais do País poderá ser utilizado para planejamento e acompanhamento de ações futuras para melhoria contínua das condições estruturais de saúde.

Fatores associados à persistência à terapia hormonal em mulheres com câncer de mama

OBJETIVO Analisar os fatores associados à persistência à hormonioterapia para câncer de mama visando à melhoria da qualidade do cuidado prestado. MÉTODOS Estudo longitudinal a partir de dados secundários. Foi analisada uma coorte de 5.861 mulheres com câncer de mama registradas em diferentes bancos de dados do Instituto Nacional de Câncer e do Sistema Único de Saúde. Todas as pacientes foram tratadas nesse hospital, que dispensa a medicação gratuitamente, e o período de seguimento foi de janeiro de 2004 a outubro de 2010. Variáveis sociodemográficas, comportamentais, clínicas, de estilos de vida e de aspectos do serviço de saúde integraram-se à análise para testar associação com a persistência ao tratamento hormonal, pelo método de Kaplan-Meier e Riscos Proporcionais de Cox. RESULTADOS A persistência geral à hormonioterapia foi de 79,0% ao final do primeiro ano e 31,0% em cinco anos de tratamento. O risco de descontinuidade à hormonioterapia mostrou-se maior entre mulheres com idade inferior a 35 anos, com estadiamento mais grave (III e IV), usuárias de álcool, que realizaram quimioterapia, e para cada hospitalização, cada exame e cada mês, entre o diagnóstico e o início do tratamento adicional. Na direção oposta, o risco de descontinuidade mostrou-se menor entre as mulheres com nível médio e superior de escolaridade, com companheiro, com história familiar de câncer, submetidas à cirurgia e que tiveram consultas com mastologista e com oncologista clínico. CONCLUSÕES Das mulheres com câncer de mama, 69,0% não persistiram ao término de cinco anos do tratamento hormonal, aumentando o risco de uma resposta clínica inadequada. Os resultados mostram aspectos do cuidado que podem conduzir a melhores respostas ao tratamento.

Proposta conceitual de telessaúde no modelo da pesquisa translacional

OBJETIVO Rever relação conceitual entre telessaúde e pesquisa translacional. MÉTODOS Realizou-se busca bibliográfica sobre telessaúde nas bases Scopus, Cochrane BVS, Lilacs e Medline com a finalidade de encontrar experiências de telessaúde conjugadas com a discussão da pesquisa translacional em saúde. A busca recuperou oito estudos, que basearam a análise dos modelos das cinco etapas da pesquisa translacional com os múltiplos fluxos de política pública no contexto brasileiro da telessaúde. Esses modelos foram aplicados às atividades de telessaúde da Rede de Bancos de Leite Humano, na Rede Universitária de Telemedicina. RESULTADOS O ciclo da pesquisa translacional do leite humano coletado, armazenado e distribuído apresentou iniciativas de telessaúde integradas, tais como videoconferências, softwares e portais de síntese do conhecimento, compondo elementos de um ecossistema de informação, mediado por tecnologias da informação e comunicação no sistema de saúde. CONCLUSÕES A telessaúde deve ser compreendida como conjunto de atividades em rede mediadas por computação e que promovem a translação do conhecimento entre pesquisa e serviços de saúde.

Integração e continuidade do cuidado em modelos de rede de atenção à saúde para idosos frágeis

Foi realizada revisão crítica da literatura sobre modelos que tenham avaliado a efetividade de redes assistenciais integradas e coordenadas para a população idosa. Foram pesquisadas as seguintes bases bibliográficas: Pubmed, The Cochrane Library, Lilacs, Web of Science, Scopus e SciELO. Doze artigos sobre cinco modelos diferentes foram incluídos para a discussão. A análise da literatura mostrou que a prestação de serviços pautava-se na atenção básica incluindo serviços domiciliares. Os usuários contavam com a integração de atenção primária, hospitalar, centros dia, serviços domiciliares e serviços sociais. O plano de cuidados e a gestão de caso foram elementos chaves para a continuidade de cuidado. Essa abordagem mostrou-se efetiva nos estudos, reduzindo o uso da atenção hospitalar, o que resultou em economia para o sistema financiador. Houve redução da prevalência de perda funcional, melhora na satisfação e na qualidade de vida dos usuários e de seus familiares. A análise da literatura reforça a necessidade de se modificar a abordagem de assistência à saúde dos idosos, e a integração e coordenação dos serviços são formas eficientes para iniciar essa mudança.

Principal components and generalized linear modeling in the correlation between hospital admissions and air pollution

OBJECTIVE To analyze the association between concentrations of air pollutants and admissions for respiratory causes in children. METHODS Ecological time series study. Daily figures for hospital admissions of children aged < 6, and daily concentrations of air pollutants (PM10, SO2, NO2, O3 and CO) were analyzed in the Região da Grande Vitória, ES, Southeastern Brazil, from January 2005 to December 2010. For statistical analysis, two techniques were combined: Poisson regression with generalized additive models and principal model component analysis. Those analysis techniques complemented each other and provided more significant estimates in the estimation of relative risk. The models were adjusted for temporal trend, seasonality, day of the week, meteorological factors and autocorrelation. In the final adjustment of the model, it was necessary to include models of the Autoregressive Moving Average Models (p, q) type in the residuals in order to eliminate the autocorrelation structures present in the components. RESULTS For every 10:49 μg/m3 increase (interquartile range) in levels of the pollutant PM10 there was a 3.0% increase in the relative risk estimated using the generalized additive model analysis of main components-seasonal autoregressive – while in the usual generalized additive model, the estimate was 2.0%. CONCLUSIONS Compared to the usual generalized additive model, in general, the proposed aspect of generalized additive model − principal component analysis, showed better results in estimating relative risk and quality of fit.

Back pain in adults living in quilombola territories of Bahia, Northeastern Brazil

OBJECTIVE To analyze the factors associated with back pain in adults who live in quilombola territories. METHODS A population-based survey was performed on quilombola communities of Vitória da Conquista, state of Bahia, Northeastern Brazil. The sample (n = 750) was established via a raffle of residences. Semi-structured interviews were conducted to investigate sociodemographics and employment characteristics, lifestyle, and health conditions. The outcome was analyzed as a dichotomous variable (Poisson regression). RESULTS The prevalence of back pain was of 39.3%. Age ≥ 30 years and being a smoker were associated with the outcome. The employment status was not related to back pain. CONCLUSIONS The survey identified a high prevalence of back pain in adults. It is suggested to support the restructuring of the local public service in order to outline programs and access to healthy practices, assistance, diagnosis, and treatment of spine problems.

Acute Hepatitis B in a patient previously positive for antibody to surface antigen (anti-HBs) determined by radioimmunoassay: case report and review of the literature

The determination of anti-HBs as a screening test before vaccination has been advisable in order to encounter immune individuals that don't need to receive vaccine protection. A case-report is presented and three other cases are reviewed from the literature. Anti-HBs was positive in these health-care personnels that developped typical acute B hepatitis. Different subtyping involving the d/y determinants were found in the first case, but false-positive anti-HBs even with high titres, determined by RIA, were found in the other cases. Concomitant determination of anti-HBc or absence of screening tests seem to be more reasonable policies until a low-cost and risk-free vaccine is produced.

An ELISA method using serum derived HDAg for the sorological detection of HDV antigens and antibodies

One of the main difficulties related to the detection of the Hepatitis Delta Virus (HDV) antigen and antibody has been the source of the needed HD antigen since HDV containing human and animal livers are very difficult to obtain and since yield is low. This fact prompted us to try to use the serum of patients in the acute phase of HDV infection as a source of HDAg and turn to enzyme immunoassays (EIA) instead of RIA for the sake of easiness and economy in the amount of HDAg needed. The antigen for EIA was obtained from patients during the acute phase of HDV infection and the antibody from patients who have been carriers for many years. For the detection of the antigen, a sandwich type method was employed, whereas for the antibody a competition assay was developed. In order to assess the relative specificity and sensibility of the test, the antibody assay was compared to a commercial RIA (C. RIA, Abbott) and to a non-commercial RIA (NC RIA). Forty-two sera were tested by the two methods and only in two cases discrepant results were obtained. Its is concluded that: 1) sera from patients in the acute and chronic phases of HDV infection can be used as source of both antigen and antibody, for immunoassays; 2) EIA and RIA have comparable relative specificity and sensibility and 3) EIA is easier to perform, cheaper, non-hazardous, has a longer shelf-life and saves scarce HDAg.

Hepatitis B vaccine - proposal for a standardized assessment of immune response

The authors developed a comparative study of the various methods of assessment of immune response to Hepatitis B vaccine. Eighty-six health care professionals underwent a vaccination programme with three doses of plasma-derived vaccine against Hepatitis B (H-B-Vax, Merck, Sharp & Dohme) given intra-muscularly. Assessment of immune response was carried out three months after the end of the programme, by radioimmunoassay (RIA) and enzymeimmunoassay (EIA). The results showed that the semi-quantitative assessment of Anti-HBs antibodies by RIA or EIA was perfectly comparable to the reference method (quantitative determination of antibodies by RIA). In view of these findings, the authors suggest a standardization of assessment of immune response to the vaccine, thus permitting correct planning of booster doses and easier comparison between different studies

Associantion between leprosy and hepatitis B infecion: a survey in Goiânia, Central Brazil

This investigation presents the results of Hepatitis B virus screening among leprosy patients conducted in Central Brazil as a preliminary information for a HBV vaccination programme. The main objectives were to assess the seroprevalence of HBV serum markers among lepromatous patients and to analyse institutionalization as risk factor for HBV infection in this population. Two groups of lepromatous patients were studied, 83 outpatients and 171 institutionalized ones. Screening for HBV serum markers included the detection of HBsAg, anti-HBc by radioimmune assay (RIA). The prevalence of carrier state (HBsAg) was 4.8% and 8.8% among outpatients and institutionalized, respectively, (p>0.05). Seroprevalence of exposure (all markers) was statistically significant different between outpatients (16.9%) and institutionalized ones (50.3%). Institutionalized patients had an almost four fold risk of HBV infection when compared to the outpatients, and the highest risks were among patients with more than 21 years of residence in the colony, after adjusting for age and sex.

PRETERM BIRTH AND FETAL GROWTH RESTRICTION IN HIV-INFECTED BRAZILIAN PREGNANT WOMEN

Introduction: Maternal HIV infection and related co-morbidities may have two outstanding consequences to fetal health: mother-to-child transmission (MTCT) and adverse perinatal outcomes. After Brazilian success in reducing MTCT, the attention must now be diverted to the potentially increased risk for preterm birth (PTB) and intrauterine fetal growth restriction (IUGR). Objective: To determine the prevalence of PTB and IUGR in low income, antiretroviral users, publicly assisted, HIV-infected women and to verify its relation to the HIV infection stage. Patients and Methods: Out of 250 deliveries from HIV-infected mothers that delivered at a tertiary public university hospital in the city of Vitória, state of Espírito Santo, Southeastern Brazil, from November 2001 to May 2012, 74 single pregnancies were selected for study, with ultrasound validated gestational age (GA) and data on birth dimensions: fetal weight (FW), birth length (BL), head and abdominal circumferences (HC, AC). The data were extracted from clinical and pathological records, and the outcomes summarized as proportions of preterm birth (PTB, < 37 weeks), low birth weight (LBW, < 2500g) and small (SGA), adequate (AGA) and large (LGA) for GA, defined as having a value below, between or beyond the ±1.28 z/GA score, the usual clinical cut-off to demarcate the 10th and 90th percentiles. Results: PTB was observed in 17.5%, LBW in 20.2% and SGA FW, BL, HC and AC in 16.2%, 19.1%, 13.8%, and 17.4% respectively. The proportions in HIV-only and AIDS cases were: PTB: 5.9 versus 27.5%, LBW: 14.7% versus 25.0%, SGA BW: 17.6% versus 15.0%, BL: 6.0% versus 30.0%, HC: 9.0% versus 17.9%, and AC: 13.3% versus 21.2%; only SGA BL attained a significant difference. Out of 15 cases of LBW, eight (53.3%) were preterm only, four (26.7%) were SGA only, and three (20.0%) were both PTB and SGA cases. A concomitant presence of, at least, two SGA dimensions in the same fetus was frequent. Conclusions: The proportions of preterm birth and low birth weight were higher than the local and Brazilian prevalence and a trend was observed for higher proportions of SGA fetal dimensions than the expected population distribution in this small casuistry of newborn from the HIV-infected, low income, antiretroviral users, and publicly assisted pregnant women. A trend for higher prevalence of PTB, LBW and SGA fetal dimensions was also observed in infants born to mothers with AIDS compared to HIV-infected mothers without AIDS.

Spatial distribution of leprosy in areas of risk in Vitoria, State of Espirito Santo, Brazil, 2005 to 2009

Introduction Leprosy remains a relevant public health issue in Brazil. The objective of this study was to analyze the spatial distribution of new cases of leprosy and to detect areas with higher risks of disease in the City of Vitória. Methods The study was ecologically based on the spatial distribution of leprosy in the City of Vitória, State of Espírito Santo between 2005 and 2009. The data sources used came from the available records of the State Health Secretary of Espírito Santo. A global and local empirical Bayesian method was used in the spatial analysis to produce a leprosy risk estimation, and the fluctuation effect was smoothed from the detection coefficients. Results The study used thematic maps to illustrate that leprosy is distributed heterogeneously between the neighborhoods and that it is possible to identify areas with high risk of disease. The Pearson correlation coefficient of 0.926 (p = 0.001) for the Local Method indicated highly correlated coefficients. The Moran index was calculated to evaluate correlations between the incidences of adjoining districts. Conclusions We identified the spatial contexts in which there were the highest incidence rates of leprosy in Vitória during the studied period. The results contribute to the knowledge of the spatial distribution of leprosy in the City of Vitória, which can help establish more cost-effective control strategies because they indicate specific regions and priority planning activities that can interfere with the transmission chain.

Factors related to severe dengue during an epidemic in Vitoria, State of Espirito Santo, Brazil, 2011

Introduction The prognosis of dengue depends on early diagnosis and treatment, which can help prevent severe forms whose characteristics were evaluated here. Methods A cross-sectional study was conducted involving dengue cases in Vitória, State of Espírito Santo, Brazil, in 2011. Results Two health regions registered 56.3% of 371 cases of severe dengue. Of these cases, 21.3% presented with dengue hemorrhagic fever. There were associations between dengue hemorrhagic fever with younger ages and a longer time before receiving care. Conclusions There was a greater involvement of dengue hemorrhagic fever in young people. Delay in care, poor urban quality and high endemicity were identified as possible risk factors for dengue severity.

Species of the subfamily Triatominae Jeannel, 1919 (Hemiptera: Reduviidae) present in the Collection of Chagas Disease Vectors (FIOCRUZ-COLVEC), State of Minas Gerais

Introduction Biological collections are depositories of information on different species and contribute to the knowledge, protection, conservation and maintenance of biodiversity. Methods A list of triatomine species currently included in the Collection of Chagas Disease Vectors (FIOCRUZ-COLVEC) was prepared from the database made available by the Reference Center on Environmental Information. Results COLVEC curatorship houses 4,778 specimens of triatomines, of which 811 come from other American countries (Argentina, Bolivia, Colombia, Costa Rica, the United States of America, Guatemala, Mexico, Peru, Uruguay and Venezuela) and 3,967 are autochthonous from Brazil. Altogether, 56 species of Chagas disease vectors are represented in the COLVEC: two species of the Tribe Cavernicolini Usinger, 1944; fifteen species of the tribe Rhodniini Pinto, 1926, of which 12 are of the genus Rhodnius and 3 are of the genus Psamolestes; and 39 species of the tribe Triatomini Jeannel, 1919, represented by the genus Dipetalogaster, two species of the genus Eratyrus, two of the genus Meccus, seven of the genus Panstrongylus and 27 of the genus Triatoma. Conclusions This list provides important data on the diversity of triatomines currently included in COLVEC, including the expanded area of Panstrongylus lutzi occurrence in the municipalities Pirapora and Januária, State of Minas Gerais. The maintenance and expansion of the collection ensures the preservation of biodiversity and further studies.

Hyperhomocyst(e)inemia in chronic stable renal transplant patients

PURPOSE: Hyperhomocyst(e)inaemia is an important risk factor for atherosclerosis, which is currently a major cause of death in renal transplant patients. The aim of this study was to assess the influence of immunosuppressive therapy on homocyst(e)inemia in renal transplant recipients. METHODS: Total serum homocysteine (by high performance liquid chromatography), creatinine, lipid profile, folic acid (by radioimmunoassay-RIA) and vitamin B12 (by RIA) concentrations were measured in 3 groups. Group I patients (n=20) were under treatment with cyclosporine, azathioprine, and prednisone; group II (n=9) were under treatment with azathioprine and prednisone; and group III (n=7) were composed of renal graft donors for groups I and II. Creatinine, estimated creatinine clearance, cyclosporine trough level, lipid profile, folic acid, and vitamin B12 concentrations and clinical characteristics of patients were assessed with the aim of ascertaining determinants of hyperhomocyst(e)inemia. RESULTS: Patient ages were 48.8 ± 15.1 yr (group I), 43.3 ± 11.3 yr (group II); and 46.5 ± 14.8 yr (group III). Mean serum homocyst(e)ine (tHcy) concentrations were 18.07 ± 8.29 mmol/l in renal transplant recipients; 16.55 ± 5.6 mmol/l and 21.44 ± 12.1 mmol/l respectively for group I (with cyclosporine) and group II (without cyclosporine) (NS). In renal donors, tHcy was significantly lower (9.07 ± 3.06 mmol/l; group I + group II vs. group III, p<0.008). There was an unadjusted correlation (p<0.10) between age (r=0.427; p<0.005) body weight (r=0.412; p<0.05), serum creatinine (r=0.427; p<0.05), estimated creatinine clearance (r=0.316; p<0.10), and tHcy in renal recipients (group I +II). Independent regressors (r²=0.46) identified in the multiple regression model were age (coefficient= 0.253; p=0.009) and serum creatinine (coefficient=8.07; p=0.045). We found no cases of hyperhomocyst(e)inemia in the control group. In contrast, 38% of renal recipients had hyperhomocyst(e)inemia: 7 cases (35%) on cyclosporine and 4 (45%) without cyclosporine, based on serum normal levels. CONCLUSIONS: Renal transplant recipients frequently have hyperhomocyst(e)inemia. Hyperhomocyst(e)inemia in renal transplant patients is independent of the scheme of immunosuppression they are taking. The older the patients are and the higher are their serum creatinine levels, the more susceptible they are to hyperhomocyst(e)inemia following renal transplantation.
