Women using addictive substances during pregnancy: the effects of substance abuse on the prenatal and postnatal development of child Blanka Nechanská Abstract Background: Substance abuse among pregnant women represents a public health issue internationally, associated with high costs to the society and at the personal level for the women and children involved. Aims: The aim of the study was to determine the basic socioeconomic characteristics of women with substance use disorder during pregnancy and selected characteristics neonatal outcomes their children. Another goal was to study the morbidity in children prenatally exposed to addictive substances by studying hospitalizations up to three years of age. Material and methods: Series of analysis within database-linkage study combining data on pregnancy and neonatal outcomes with data from in-patient treatment in CR in 2000-2014 was performed. The sample consisted of pregnant women diagnosed with substance use disorder during pregnancy and women from general population, and their children. Neonatal outcomes were gestational age, birth weight and length, preterm birth, and intrauterine growth restriction (Small-for-Gestational-Age, SGA). Information on the number of hospita- lizations, treatment time and diagnostic groups according to ICD-10 were outcomes of...

O objetivo deste estudo foi analisar a distribuição espacial dos óbitos por tuberculose pulmonar e sua relação com indicadores sociais em São Luís-MA. Trata-se de um estudo ecológico em que foram considerados os óbitos ocorridos na zona urbana do município entre 2008 e 2012, segundo as causas A15.0 a A15.3 e A16.0 a A16.2 (CID-10), disponíveis no Sistema de Informação sobre Mortalidade. Procedeu-se inicialmente as análises univariada e bivariada das variáveis sociodemográficas e operacionais dos óbitos investigados. Para construção dos indicadores sociais utilizou-se a análise de componentes principais, sendo selecionadas variáveis das áreas de ponderação do Censo Demográfico de 2010. Recorreu-se à regressão linear múltipla, pelo método dos mínimos quadrados e à regressão espacial para análise da relação de dependência espacial entre os indicadores sociais e as taxas de mortalidade padronizadas pela idade por meio do Teste Global I de Moran. Utilizou-se ainda técnicas de estatística de varredura para a detecção de aglomerados espaciais e espaço- temporais dos óbitos nos setores censitários do município, sendo empregado o modelo discreto de Poisson. A geocodificação dos óbitos foi processada no TerraView versão 4.2.2, sendo considerados também nas análises os softwares Arcgis-versão 10.1, Statistica versão 12.0, OpenGeoDa versão 1.0, R versão 3.0.2 e SaTScanTM versão 9.2. Em todos os testes, foi fixado o nível de significância em alfa de 5% (p< 0,05). Identificou-se 193 indivíduos que evoluíram para óbito por tuberculose pulmonar, com idade mediana de 52 anos, sendo maior percentual referente ao sexo masculino (n=142; 73,60%), raça/cor parda (n=133; 68,91%), estado civil solteiro (n=102; 53,13%), ensino fundamental completo (n=64; 33,16%) e com ocorrência do óbito no hospital (n=143; 74,08%). Observou-se que não ter assistência médica previamente ao óbito teve associação estatisticamente significativa com a realização de necropsia (p=0,001). Foram geocodificados 95% dos óbitos e as taxas de mortalidade por tuberculose pulmonar padronizadas pela idade variaram de 0,00 a 8,10 óbitos/100.000 habitantes-ano. Na construção dos indicadores sociais, duas novas variáveis surgiram, apresentando variância total de 73,07%. A primeira componente (56,75%) foi denominada indicador de bem-estar social e a segunda (16,32%), indicador de iniquidade social, que, na regressão linear múltipla, apresentou-se estatisticamente significante (R2 =23,86%; p=0,004), verificando-se posteriormente a existência de dependência espacial (Moran I=0,285; p<0,001), sendo o Erro Espacial o melhor modelo explicativo. Foi possível evidenciar ainda que áreas de ponderação com alta e intermediária iniquidade social apresentaram as maiores taxas de mortalidade. Na análise de varredura espacial, identificou-se dois aglomerados espaciais, sendo um de alto risco relativo (RR=3,87; p<0,001) e outro de baixo (RR=0,10; p=0,002), enquanto que a análise espaço-temporal evidenciou apenas um aglomerado de alto risco relativo (RR=3,0; p<0,001) que ocorreu entre novembro de 2008 e abril de 2011. A investigação revelou áreas prioritárias para investimentos em tecnologias de saúde e um perfil de população fatalmente atingida pela doença, evidenciando aspectos importantes a serem considerados em termos de gestão e organização dos serviços de saúde para a equidade no acesso. / This study aimed to analyze the spatial distribution of deaths by pulmonary tuberculosis and the relation with social indicators, in São Luís-MA. It is an ecological study that considered deaths occurring in the urban area of the municipality, between 2008 and 2012, according to causes A15.0 to A15.3 and A16.0 to A16.2 (ICD-10), which are available in the Mortality Information System. It was initially used univariate and bivariate analyzes of demographic and operational variables from the investigated deaths. For the construction of social indicators, it was possible to use the principal components analysis, with variables selected from weighting areas of the Population Census, in 2010. It was utilized the multiple linear regression through the method of least squares and spatial regression to analyze the spatial dependence relationship between social indicators and standardized mortality rates by age, and with the Global I Test of Moran. Also, it was possible to use statistical techniques of scanning for detecting spatial-temporal and spatial clusters of deaths, in the municipality census tracts, and with the use of Poisson\'s discrete model. The geocoding of deaths was processed in TerraView version 4.2.2, and it was also considered, in the analysis, the softwares Arcgis version 10.1, Statistica version 12.0, OpenGeoDa version 1.0, R version 3.0.2 and SaTScanTM version9.2. It was fixed, in all tests, the level of significancein alpha of 5% (p<0.05). It was identified 193 individuals who died due to pulmonary tuberculosis, with a median age of 52 years, with higher percentage for males (n=142, 73.60%), mulatto race (n=133, 68.91%), single marital status (n=102, 53.13%), complete primary school (n=64, 33.16%), and with deaths at the hospital (n=143, 74.08%). It was seen that having no medical care prior to death was statistically associated with the performance of necropsy (p=0.001). It was possible to geocode 95% of deaths, and death rates due to pulmonary tuberculosis standardized by age ranged from 0.00 to 8.10 deaths per 100.000 inhabitants a year. In the construction of social indicators, two new variables emerged and showed a total variance of 73.07%. The first (56.75%) was denominated indicator of social welfare, and the second (16.32%) as an indicator of social inequity, which was statistically significant in the multiple linear regression (R2 =23.86 %, p=0.004). It was verified the existence of spatial dependence (Moran I=0.285, p<0.001), and the Spatial Error was the best explanatory model. It was also possible to show that weighting areas with high and intermediate social inequity presented the highest mortality rates. In the analysis of spatial scan, it was identified two spatial clusters, one of relatively high risk (RR=3.87, p<0.001) and the other one of low risk (RR=0.10, p=0.002). On the other hand, the spatial-temporal analysis evidenced only a cluster of relatively high risk (RR=3.0, p<0.001), which happened between November, 2008 and April, 2011. The research revealed priority areas for investments on health technology, and population profile fatally afflicted by the disease. It also pointed important aspects to be considered in terms of management and organization of health services for an equity access.

A saúde pública no país é uma área de alta demanda, dependente de tecnologia cara e de rápida obsolescência, com custos operacional e de manutenção altos, e com uma cobrança de crescimento ininterrupto, decorrente tanto do aumento vegetativo dos usuários, quanto da instabilidade social, quando os desempregados perdem a condição de se utilizar da saúde suplementar e migram para a rede pública. Há um agravamento de tal situação pela dispersão geográfica da população, pelo tamanho do país. O Sistema Único de Saúde, através do PlanejaSUS, tem um esforço continuado de planejar o funcionamento da saúde pública no país, para o que se utiliza, entre outros recursos, dos seguintes sistemas: de Informações sobre Nascidos Vivos; de Informação de Agravos de Notificação; de Informações Hospitalares; e de Informação de Mortalidade. Com o objetivo de identificar o grau de consistência dos mesmos, foi feito um levantamento de periódicos dos últimos 5 anos, de artigos que apontavam tal característica. Mediante a utilização de recortes dos artigos, análise e tabulação de resultados, identificou-se o predomínio de deficiências de pessoal e de qualidade das informações, estas últimas decorrentes das primeiras. Em apenas um caso houve queixa da infraestrutura de tecnologia da informação. Conclui-se pela priorização de trabalhos de persuasão e capacitação de funcionários; por um ajuste na expectativa pela precisão dos sistemas, já que por seu macro dimensionamento, face à dispersão geográfica e ao grande número de pessoas envolvidas, são sistemas com tendência natural à instabilidade; pelo papel que pesquisas como as apresentadas nos artigos podem fazer no controle de tais sistemas; pela consistência apresentada atualmente pelos sistemas, que embora não seja ótima, tem sustentado inúmeras pesquisas cujos resultados são validados por subsídios da literatura e cruzamento de bancos de dados. Aventa-se ainda a possibilidade de, em um trabalho de parceria entre universidades, centros de pesquisa, e o Sistema Único de Saúde, este último estabeleça alguns eixos e categorias, e estimule continuadamente pesquisas voltadas para identificação do nível de consistência dos sistemas mencionados, pesquisas estas cujos resultados poderão funcionar na redução da instabilidade dos mesmos / Public health in the country is a department of high demand, dependent on expensive technology and quick obsolescence, with high operational and maintenance costs, and with a charge of uninterrupted growth, due to both the vegetative growth of users, and the social instability, when the unemployed lose the condition of using additional health system and migrate to the public service.

The Sistema Único de Saúde (Unified Health System), through the PlanejaSUS, mantain a continued effort of planning the operation of public health in the country, for what it use, among other features, the following systems: information on live borns; reportable diseases information; hospital information; and mortality information. In order to identify the consistency degree of these systems was made a survey of the past 5 years, using articles that pointed such feature. Using cutouts of articles, analysis and tabulation of results, it was identified the predominance of disabilities of personnel and quality of the information, the latter arising out of the first.

The mortality of thoracic aortic diseases (mainly aneurysms and dissections) is high, even with surgical treatment. Epidemiology and long-term outcomes are incompletely investigated. Stroke is a major complication contributing to mortality, morbidity, and possibly to reduced quality of life. Study I Increasing incidence of thoracic aortic diseases 1987 – 2002 was demonstrated (n=14229). Annual number of operations increased eight-fold. Overall long-time survival was 92%, 77%, and 57% at 1, 5, and 10 years. Risk of operative and long-term mortality was reduced across time. Study II 2634 patients operated on the proximal thoracic aorta (Swedish Heart Surgery register) were examined. Aortic valve replacement, coronary revascularization, emergency operation, and age were independently associated with surgical death. Long-term mortality was similar for aneurysms and dissections. Operative mortality was reduced (13.7% vs 7.2%) for aneurysms but remained unchanged (22.3% vs 22.4%) for dissections across time. Study III 65 patients underwent selective antegrade cerebral perfusion (SACP) uni- or bilaterally. Stroke was significantly more common after unilateral SACP (29% vs 8%, p=0.045), confirmed by propensity score-matched analysis. Subclavian artery cannulation with Seldinger-technique entailed vascular complication in one case (1.5%). Study IV Near-infrared spectroscopy (NIRS) was used to monitor cerebral tissue saturation (rSO2) during SACP in 46 patients. Lower rSO2 were encountered (1) in patients suffering a stroke (2) with unilateral SACP, and (3) in the affected hemisphere of stroke victims. A decrease of rSO2 by 14 – 21% from baseline increased the risk of stroke significantly. Study V Quality of life (QoL) in 76 survivors of thoracic aortic surgery was examined with the SF-36 health questionnaire. Except for pain, QoL was reduced in all dimensions. QoL was not affected by acuity of operation. Tendencies of lower QoL after descending aortic operations, after major complications, and with persistent dysfunction were non-significant.
