Economic Cost of Air Pollution in Cubatao - SP Based on Health Expenses Related to Diseases of the Respiratory and Circulatory Systems

The aim of this research was to evaluate economic costs of respiratory and circulatory diseases in the municipality of Cubatao, in the state of Sao Paulo, Brazil. Data on hospital admissions and on missed working days due to hospitalization (for age group 14 to 70 years old) from the database of Sistema Unico de Sa de (SUS - Brazilian National Health System) were used. Results: Based on these data, it was calculated that R$ 22.1 million were spent in the period 2000 to 2009 due to diseases of the respiratory and circulatory systems. Part of these expenses can be directly related to the emission of atmospheric pollutants in the city. In order to estimate the costs related to air pollution, data on Cubatao were compared to data from two other municipalities that are also located at the coast side (Guaruja and Peru be), but which have little industrial activity in comparison to Cubatao. It was verified that, in both, average per capita costs were lower when compared to Cubatao, but that this difference has been decreasing in recent years.

Measuring the burden of disease in Shandong province : an adoption of the disability-adjusted life year [应用伤残调整寿命年测量山东省居民疾病负担]

Objective To estimate the burden of diseases in Shandong province by the means of DALY (Disability- adjusted life year) thus to investigate the key public health problems referencing for health policy making. Methods DALYs were calculated following the procedures developed for the Global Burden of Disease (GBD) study to ensure comparability. We measured YLLs using the mortality data of 19 Disease Surveillance Points (DSPs) in Shandong Province during 2000 and 2005. YLDs were estimated based on data for WPRO in the 2002 GBD study published by WHO. Results During this period, the average DALYs loss by all causes for the residents of DSPs in Shandong was 149.74 per thousand persons each year. Noncommunicable diseases accounted for 76.63% of the disability adjusted life years, communicable diseases and other disorders represented 14.13%, and injuries 9.24%. Nearly half of the DALYs (45%) happened among the elderly (60+). Malignant neoplasm was the number one cause of DALYs loss in the male, followed by neuropsychiatric disorder, injury, cerebrovascular disease, heart disease，etc. However, neuropsychiatric disorder possessed the largest single contributor to DALY in the female and followed by heart disease, malignant neoplasm, cerebrovascular disease and respiratory disease. Conclusion Non-communicable diseases such as circulatory diseases, neuropsychiatric disorders and malignant neoplasms were the main causes of disease burden in Shandong province. The importance of neuropsychiatric disorders was more striking and should be recognized properly. The lack of morbidity data is the main limitation of this study.

Prevenção das doenças cerebrovasculares no Brasil, no âmbito da atenção primária à saúde

As doenças crônicas não transmissíveis (DCNT) estão posicionadas no topo das enfermidades em termos de morbimortalidade, no Brasil e no mundo. Entre estas, as doenças cardiovasculares (DCV), e particularmente, as cerebrovasculares (DCbV), produzem um impacto significativo sobre a autonomia das pessoas, desfalcando a força de trabalho das nações e gerando um alto custo para a previdência social de todos os países. No Brasil, só muito recentemente as enfermidades circulatórias passaram a ser contempladas por políticas públicas formuladas pelo Ministério da Saúde (MS), não só pela manutenção destas doenças em altos patamares de morbimortalidade, mas também pelo crescimento exponencial de alguns dos seus fatores de risco. Partindo do pressuposto que as políticas e programas oficiais não estão sendo efetivamente implementados no âmbito da Atenção Primária à Saúde (APS), o objetivo do presente estudo foi investigar e analisar como estas iniciativas do MS vem sendo efetivamente executadas em Juiz de Fora-MG. A estratégia utilizada para essa investigação consistiu em uma pesquisa qualiquantitativa com base em observação, documentos e entrevistas semi-estruturadas com os diferentes componentes profissionais das Equipes de Saúde da Família de três unidades básicas de saúde do município citado. Foram entrevistados 40 profissionais de saúde, entre médicos, enfermeiros e agentes comunitários de saúde, buscando-se entender como os programas governamentais com interface com a prevenção das doenças cardiovasculares e, em especial, cerebrovasculares, vêm sendo implementados ao nível do Programa de Saúde da Família. Na comparação entre o que é recomendado nos programas governamentais e o que vem sendo executado nas UBS, concluiu-se que ainda há um longo caminho a ser percorrido para que estes programas sejam efetivamente implementados na porta de entrada do sistema de saúde.

Efeitos de modificação dietética associada ou não a uma rotina de exercícios aeróbicos na microcirculação em modelo animal de obesidade exógena

A obesidade atinge proporções epidêmicas em países industrializados e está relacionada a uma série de doenças metabólicas e circulatórias. Nesse contexto, a atividade física, tratamento não farmacológico da obesidade, acessível a diversas populações e está relacionada com a redução do risco cardiovasvascular mesmo. O objetivo deste trabalho foi avaliar, após mudança ou não da dieta, associação ou não a um programa de treinamento aeróbico (PTA) durante 8 semanas, a possível reversibilidade dos danos causados por uma dieta hiperlipídica por 12 semanas. Para tal, 120 hamsters machos da espécie Mesocricetus auratus, com massa corporal de 60 g, foram distribuídos em quatro grupos, cada um subdividido em três subgrupos, com dez animais para diferentes análises. Os grupos Obeso Controle (OBC) e Obeso Exercitado (OBEX) receberam a ração hiperlipídica por 20 semanas, com adição do PTA ao grupo OBEX nas últimas 8 semanas. Os Obeso Ração Padrão (OBRP) e Obeso Ração Padrão/Exercício (OBRP/EX) tiveram a ração modificada para comercial padrão e adição do PTA ao grupo OBRP/EX após as 12 semanas iniciais. Para as análises microcirculatórias, a bolsa da bochecha foi usada para determinação do número máximo de extravasamentos induzidos por 30 min de isquemia seguida de reperfusão e da reatividade microvascular após a aplicação tópica de acetilcolina e nitroprussiato de sódio. No sangue coletado foi avaliado o perfil lipídico, glicemias quinzenais e leptina. As expressões de eNOS e iNOS foram determinadas na aorta por imunoblotting e a composição corporal avaliada nos tecidos adiposos visceral, urogenital e retroperitoneal, retirados no dia do experimento. Os resultados foram analisados com os métodos o teste estatístico de análise de variância (One Way ANOVA - Teste de Kruskal-Wallis), seguido pelo pós-teste de Dunn. Resultados mostram que a modificação dietética, associada ou não ao PTA, reduziu significativamente a massa corporal (p<0,0001), comprimento naso-anal (p=0,0011) e tecido adiposo (visceral [p<0,0001], urogenital [p=0.0004] e retroperitoneal [p= 0,0083]). Nas análises sanguíneas não foram encontradas diferenças com relação ao perfil lipídico e glicemia, já na leptina houve uma redução significativa (p=0,0039). A análise da reatividade microvascular mostrou melhora significativa na vasodilatação endotélio-dependente nos grupos submetidos à modificação dietética associada ou não ao PTA. Nas medidas de permeabilidade a macromoléculas houve redução significativa no número de extravasamentos nos grupos submetidos à modificação dietética associada ou não ao PTA, (5 min [p= 0,0207] e 10 min [p= 0,0057]). Houve um aumento na expressão de eNOS nos grupos submetidos à modificação dietética associada ou não ao PTA, em comparação ao grupo OBC (p=0,0352). Os resultados mostraram que a modificação dietética, associada ao protocolo de treinamento aeróbico melhora a vasodilatação endotélio-dependente, aumenta a expressão da óxido nítrico sintase endotelial e reduz o número de extravasamentos induzidos por isquemia e reperfusão, mesmo sem melhoras nos marcadores bioquímicos tradicionais como glicemia e perfil lipídico.

Fractal structures in stenoses and aneurysms in blood vessels

Recent advances in the field of chaotic advection provide the impetus to revisit the dynamics of particles transported by blood flow in the presence of vessel wall irregularities. The irregularity, being either a narrowing or expansion of the vessel, mimicking stenoses or aneurysms, generates abnormal flow patterns that lead to a peculiar filamentary distribution of advected particles, which, in the blood, would include platelets. Using a simple model, we show how the filamentary distribution depends on the size of the vessel wall irregularity, and how it varies under resting or exercise conditions. The particles transported by blood flow that spend a long time around a disturbance either stick to the vessel wall or reside on fractal filaments. We show that the faster flow associated with exercise creates widespread filaments where particles can get trapped for a longer time, thus allowing for the possible activation of such particles. We argue, based on previous results in the field of active processes in flows, that the non-trivial long-time distribution of transported particles has the potential to have major effects on biochemical processes occurring in blood flow, including the activation and deposition of platelets. One aspect of the generality of our approach is that it also applies to other relevant biological processes, an example being the coexistence of plankton species investigated previously.

Perfil de mortalidade de idosos no Rio Grande do Norte: estudo comparativo entre duas faixas etárias e fatores relacionados

Measures of mortality represent one of the most important indicators of health conditions. For comprising the larger rate of deaths, the study of mortality in the elderly population is regarded as essential to understand the health situation. In this sense, the present study aims to analyze the mortality profile of the population from 60 to 69 (young elders) and older than 80 years old (oldest old) in the Rio Grande do Norte state (Brazil) in the period 2001 to 2011, and to identify the association with contextual factors and variables about the quality of the Mortality Information System (SIM). For this purpose, Mortality Proportional (MP) was calculated for the state and Specific Mortality Rate by Age (CMId) , according to chapters of ICD- 10, to the municipalities of Rio Grande do Norte , through data from the Mortality Information System (SIM) and the Brazilian Institute of Geography and Statistics (IGBE). In order to identify groups of municipalities with similar mortality profiles, Nonhierarchical Clustering K-means method was applied and the Factor Analysis by the Principal Components Analysis was resort to reduce contextual variables. The spatial distribution of these groups and the factors were visualized using the Spatial Analysis Areas technique. During the period investigated, 21,813 younger elders deaths were recorded , with a predominance of deaths from circulatory diseases (32.75%) and neoplasms (22.9 %) . Among the oldest old, 50,637 deaths were observed, which 35.26% occurred because of cardiovascular diseases and 17.27% of ill-defined causes. Clustering Analysis produced three clusters to the two age groups and Factor Analysis reduced the contextual variables into three factors, also the sum of the factor scores was considered. Among the younger elders, the groups are called misinformation profile, development profile and development paradox, which showed a statistically significant association with education and poverty and extreme poverty factors, factorial sum and the variable related to underreporting of deaths. Misinformation profile remained in the oldest old group, accompanied by the epidemiological transition profile and the epidemiological paradox, that were statistically associated with the development and health factor, as well as with the variables that indicate the SIM quality: proportion of blank fields about the schooling and underreporting. It proposed that the mortality profiles of the younger elders and oldest old differ on the importance of the basic causes and that are influenced by different contextual aspects , observing that 60 to 69 years group is more affected by such aspects. Health inequalities can be reduced by measures aimed to improve levels of education and poverty, especially in younger elders, and by optimizing the use of health services, which is more associated to the oldest old health situation. Furthermore, it is important to improve the quality of information for the two age groups

O estudo traça um perfil da morbi-mortalidade feminina no Estado de São Paulo, com enfoque nos problemas reprodutivos. A mortalidade foi estudada nos períodos 1979-81; 1986-88 e 1993-5, a partir do Sistema de Informação em Mortalidade (SIM/DATASUS) e a morbidade de 1996 foi obtida do Sistema de Informações Hospitalares (SIH/DATASUS). O artigo discute as principais causas de internação e morte das mulheres e aponta os desafios para as políticas públicas voltadas a saúde da mulher.

Estudo de sobrevivência de uma coorte de pessoas de 60 anos e mais no município de Botucatu (SP) - Brasil

O aumento proporcional do número de idosos na população tem motivado estudos no sentido de melhorar a qualidade de vida desta faixa etária através de políticas sociais e, entre elas, o planejamento em saúde. Com o objetivo de conhecer riscos de mortalidade para a população de sessenta anos e mais, um estudo de sobrevida foi realizado rastreando, no ano de 1992, os idosos participantes de um inquérito de morbidade referida realizado na cidade de Botucatu em 1983/84. Foram localizados 89,6% destes idosos. Curvas de sobrevivência foram calculadas com o método de Kaplan-Meier e a análise de riscos, utilizando-se a Regressão Múltipla de Cox ajustando-se o modelo agregando as variáveis por blocos. Para o sexo masculino foram encontradas associadas, independentemente, ao aumento da mortalidade as seguintes categorias de variáveis: idade de 70 anos e mais: Hazard Ratio (HR)=2,4 (1,6 - 3,7); salário menor que um salário mínimo: HR=2,2 (1,3 - 3,8); ter outras rendas: HR=2,2 (1,3 - 3,9); ser o chefe da família ou seu cônjuge: HR=2,3 (1,2 - 2,4); referência de doenças do aparelho circulatório: HR=1,6 (1,1 - 2,4); referência de diabetes mellitus: HR=3,0 (1,3 - 7,0). Para o sexo feminino, foram encontradas associadas a idade de 70 anos e mais: HR=4,6 (3,0 - 7,1); referência de diabetes mellitus: HR=3,0 (1,7-5,3) e ter outras rendas: HR=2,0 (1,1 - 4,0).

Mortalidade de idosos em município do Sudeste brasileiro de 2006 a 2011

O objetivo foi descrever a mortalidade entre idosos em Araraquara (SP), no período de 2006 a 2011. Estudo epidemiológico descritivo, tendo como fontes de dados o Sistema de Informações sobre Mortalidade e a Fundação Sistema Estadual de Análise de Dados. Foi calculada razão entre coeficientes de mortalidade por ponto (R) e por intervalo de 95% de confiança (IC95%). Observou-se mais de 60% dos idosos com nível baixo de escolaridade, sendo que 76% faleceram em hospitais. Entre 2006 e 2008, as diferenças foram estatisticamente significantes entre homens e mulheres, predominando as doenças circulatórias com R = 1,41 (IC95%:1,24-1,58), respiratórias com R = 1,49 (IC95%:1,22-1,76) e neoplasias com R = 1,79 (IC95%: 1,40-2,18). Entre 2009 e 2011, obteve-se, para as causas circulatórias R = 1,18 (IC95%:1,03-1,33), sendo significativas as diferenças para as respiratórias com R = 1,33 (IC95%:1,11-1,55) e câncer sendo R = 1,94 (IC95%:1,53-2,35). O diabetes mellitus e as causas externas apareceram, respectivamente, como quarta e quinta causas de mortes mais frequentes na população idosa. O padrão de mortalidade encontrado ressalta a importância de ações voltadas à redução das principais causas de morte, como o incremento da cobertura da vacina contra a influenza e o controle da hipertensão arterial e do diabetes mellitus.

Tendência de mortalidade de idosos por doenças crônicas no município de Marília-SP, Brasil: 1998 a 2000 e 2005 a 2007

OBJECTIVE: to describe elderly mortality from cardiovascular and respiratory diseases and neoplasms in Marilia (SP). METHODS: this is a descriptive study of mortality from three diseases as defined by the 10th International Classification of Diseases, between 1998-2000 and 2005-2007. Mortality Information System records were used. Mortality rates by age and sex were calculated. RESULTS: circulatory diseases were the main causes of death among the elderly (39.25%). Neoplasm decline was noticed in both sexes and in those aged 60-69, particularly prostate cancer in men (-83.86%) and breast cancer (-70.96%) in this age group. Deaths from respiratory diseases increased in patients aged 80 and older: 39.31% in men and 57.92% in women. CONCLUSION: mortality from circulatory diseases and neoplasms among the elderly showed a decline, with increased mortality from respiratory system problems in patients 80 years of age and older.

Clima e vulnerabilidade socioespacial: uma avaliação dos fatores de risco na população urbana do município de São Luís (MA)

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)

Impact of urban atmospheric environment on hospital admissions in the elderly

OBJECTIVE: To analyze the impact of intra-urban atmospheric conditions on circulatory and respiratory diseases in elder adults. METHODS: Cross-sectional study based on data from 33,212 hospital admissions in adults over 60 years in the city of Sao Paulo, southeastern Brazil, from 2003 to 2007. The association between atmospheric variables from Congonhas airport and bioclimatic index, Physiological Equivalent Temperature, was analyzed according to the district's socioenvironmental profile. Descriptive statistical analysis and regression models were used. RESULTS: There was an increase in hospital admissions due to circulatory diseases as average and lowest temperatures decreased. The likelihood of being admitted to the hospital increased by 12% with 1 degrees C decrease in the bioclimatic index and with 1 degrees C increase in the highest temperatures in the group with lower socioenvironmental conditions. The risk of admission due to respiratory diseases increased with inadequate air quality in districts with higher socioenvironmental conditions. CONCLUSIONS: The associations between morbidity and climate variables and the comfort index varied in different groups and diseases. Lower and higher temperatures increased the risk of hospital admission in the elderly. Districts with lower socioenvironmental conditions showed greater adverse health impacts.

Cause-Specific Long-Term Mortality in Survivors of Childhood Cancer in Switzerland: A Population Based Study.

Survivors of childhood cancer have a higher mortality than the general population. We describe cause-specific long-term mortality in a population-based cohort of childhood cancer survivors. We included all children diagnosed with cancer in Switzerland (1976-2007) at age 0-14 years, who survived ≥5 years after diagnosis and followed survivors until December 31, 2012. We obtained causes of death (COD) from the Swiss mortality statistics and used data from the Swiss general population to calculate age-, calendar year- and sex-standardized mortality ratios (SMR), and absolute excess risks (AER) for different COD, by Poisson regression. We included 3'965 survivors and 49'704 person years at risk. Of these, 246 (6.2%) died, which was 11 times higher than expected (SMR 11.0). Mortality was particularly high for diseases of the respiratory (SMR 14.8) and circulatory system (SMR 12.7), and for second cancers (SMR 11.6). The pattern of cause-specific mortality differed by primary cancer diagnosis, and changed with time since diagnosis. In the first 10 years after 5-year survival, 78.9% of excess deaths were caused by recurrence of the original cancer (AER 46.1). Twenty-five years after diagnosis, only 36.5% (AER 9.1) were caused by recurrence, 21.3% by second cancers (AER 5.3) and 33.3% by circulatory diseases (AER 8.3). Our study confirms an elevated mortality in survivors of childhood cancer for at least 30 years after diagnosis with an increased proportion of deaths caused by late toxicities of the treatment. The results underline the importance of clinical follow-up continuing years after the end of treatment for childhood cancer. This article is protected by copyright. All rights reserved.

Recent changes in heart failure hospitalisations in Australia

Aim: To assess trends in admissions of patients with heart failure (HF) to all hospitals in Australia between 1996-1997 and 2003-2004. Methods and results: We carried out a retrospective analysis of the official population-based National Hospital Morbidity Data in Australia. Although the absolute number of separations with a principal diagnosis of HF remained stable, the age- and sex-standardized separation rate for HF recorded as principal diagnosis decreased from 2.0 per 1000 population in 1996-1997 to 1.6 per 1000 population in 2003-2004. The corresponding values for HF recorded in any diagnostic position were 7.7 and 4.7 per 1000 population. Men had higher in-hospital mortality than women (8.9% versus 8.1%,p < 0.001) and also a larger decrease in this measure over the study period (21.9% versus 14.4%). While the geometric mean length of stay for HF as principal diagnosis fell from 5.4 days in 1996-1997 to 4.9 days in 2003-2004, the proportion of bed-days related to such diagnoses relative to total bed days attributed to circulatory diseases increased from 12.8% to 13.7% (p < 0.001). Conclusion: There were no increase in number of admissions involving HF and standardized rates of hospital separations with HF fell in Australia between 1996 and 2004. The explanation for the observed declines in in-hospital case fatality and the separation rates should be sought in whole-of-community studies. (c) 2006 European Society of Cardiology.
