The impact of cardiopulmonary bypass time on the Sequential Organ Failure Assessment score after cardiac surgery.

OBJECTIVES: Postoperative organ dysfunction is common after cardiac surgery, particularly when cardiopulmonary bypass (CPB) is used. The Sequential Organ Failure Assessment (SOFA) score is validated to predict morbidity and mortality in cardiac surgery. However, the impact of CPB duration on postoperative SOFA remains unclear. METHODS: This is a retrospective study. Categorical values are presented as percentages. The comparison of SOFA groups utilized the Kruskal-Wallis chi-squared test, complemented by ad hoc Dunn's test with Bonferroni correction. Multinomial logistics regressions were employed to evaluate the relationship between CPB time and SOFA. RESULTS: A total of 1032 patients were included. CPB time was independently associated with higher postoperative SOFA scores at 24 h. CPB time was significantly higher in patients with SOFA 4-5 (**P = 0.0022) or higher (***P < 0.001) when compared to SOFA 0-1. The percentage of patients with no/mild dysfunction decreased with longer periods of CPB, down to 0% for CPB time >180min (50% of the patients with >180m in of CPB presented SOFA ≥ 10). The same trend is observed for each of the SOFA variables, with higher impact in the cardiovascular and renal systems. Severe dysfunction occurs especially >200 min of CPB (cardiovascular system >100 min; other systems mainly >200 min). CONCLUSIONS: CPB time may predict the probability of postoperative SOFA categories. Patients with extended CPB durations exhibited higher SOFA scores (overall and for each variable) at 24 h, with higher proportion of moderate and severe dysfunction with increasing times of CPB.

Clinical Assessment of Short (> 6 mm and ≤ 8.5 mm) Implants in Posterior Sites with an Average Follow-Up of 74 Months: A Retrospective Study.

PURPOSE: To evaluate the survival and success rates of short (> 6 mm and ≤ 8.5 mm) implants after at least 2 years of functional loading. Implants were assessed using clinical parameters such as marginal bone loss (MBL), pocket depth (PD), keratinized mucosa width (KMW), bleeding on probing (BoP), and the peri-implant condition (mucositis or peri-implantitis). Any correlations between clinical parameters were analyzed. MATERIALS AND METHODS: This observational and retrospective study included 114 posterior maxillary and mandibular implants placed in 27 women and 38 men with a mean age of 68.04 ± 9.07 years. Patients included in the study had received at least one short implant between 2001 and 2013, such that each implant was in occlusal function for at least 2 years by 2015. Patients with only long (≥ 10 mm) implants, patients with any systemic condition, and smokers were excluded from the study. PD, KMW, peri-implant condition, BoP, and MBL were the clinical parameters assessed in the study. Data on prosthesis type (single or splinted) and implant features were also obtained. All data were submitted to analysis via Mann-Whitney unpaired test, with a significance level of P < .05. Spearman correlation coefficient was also measured to verify the negative or positive correlation. RESULTS: The mean follow-up time was 74.08 months, and mean implant success and survival rates were 87.63% and 94.74%, respectively. There were 6 implant failures (5.26%). A total of 66 (59.46%) prostheses were screw-retained implant-supported restorations, and 45 (40.54%) were cemented. A total of 93 (86.49%) short implants were splinted to another implant, and 15 out of 111 (13.51%) restorations were single implants. Keratinized mucosa was missing around 43 (39%) implants, whereas PD was measured to be between 0 and 3 mm in 64.86% of implants and ≥ 4 mm in 31.53% of implants. MBL was ≤ 1.5 mm in 71.17% of cases and > two-thirds the length of the implant in 2.71% of cases. Mucositis and peri-implantitis were found in 22.52% and 7.21% of implants, respectively. The correlation coefficient showed a positive result for PD and MBL (0.11; P = .368) and negative results for PD and KMW (-0.42; P = .002) and KMW and MBL (-0.19; P = .183). CONCLUSIONS: Within the limitations of this study, it is possible to conclude that short implants are a feasible treatment option for dental rehabilitation. They are considered an excellent alternative to complex procedures and have high survival rates after at least 2 years of follow-up, with compatible peri-implant local tissue response. Moreover, a significant negative correlation between KMW and PD was observed.

Sequential Organ Failure Assessment Score in the ICU As a Predictor of Long-Term Survival After Cardiac Surgery.

OBJECTIVES: The Sequential Organ Failure Assessment (SOFA) score is a predictor of mortality in ICU patients. Although it is widely used and has been validated as a reliable and independent predictor of mortality and morbidity in cardiac ICU, few studies correlate early postoperative SOFA with long-term survival. DESIGN: Retrospective observational cohort study. SETTING: Tertiary academic cardiac surgery ICU. PATIENTS: One-thousand three-hundred seventy-nine patients submitted to cardiac surgery. INTERVENTIONS: SOFA 24 hours, SOFA 48 hours, mean, and highest SOFA scores were correlated with survival at 12 and 24 months. Wilcoxon tests were used to analyze differences in variables. Multivariate logistic regressions and likelihood ratio test were used to access the predictive modeling. Receiver operating characteristic curves were used to assess accuracy of the variables in separating survivor from nonsurvivors. MEASUREMENTS AND MAIN RESULTS: Lower SOFA scores have better survival rates at 12 and 24 months. Highest SOFA and SOFA at 48 hours showed to be better predictors of outcome and to have higher accuracy in distinguishing survivors from nonsurvivors than initial SOFA and mean SOFA. A decreasing score during the first 48 hours had mortality rates of 4.9%, while an unchanged or increased score was associated with a mortality rate of 5.7%. CONCLUSIONS: SOFA score in the ICU after cardiac surgery correlated with survival at 12 and 24 months. Patients with lower SOFA scores had higher survival rates. Differences in survival at 12 months were better correlated with the absolute value at 48 hours than with its variation. SOFA score may be useful to predict long-term outcomes and to stratify patients with higher probability of mortality.

Tracking the emergence of disparities in the subnational spread of COVID-19 in Brazil using an online application for real-time data visualisation: A longitudinal analysis.

BACKGROUND: Brazil is one of the countries worst affected by the COVID-19 pandemic with over 20 million cases and 557,000 deaths reported by August 2021. Comparison of real-time local COVID-19 data between areas is essential for understanding transmission, measuring the effects of interventions, and predicting the course of the epidemic, but are often challenging due to different population sizes and structures. METHODS: We describe the development of a new app for the real-time visualisation of COVID-19 data in Brazil at the municipality level. In the CLIC-Brazil app, daily updates of case and death data are downloaded, age standardised and used to estimate the effective reproduction number (Rt ). We show how such platforms can perform real-time regression analyses to identify factors associated with the rate of initial spread and early reproduction number. We also use survival methods to predict the likelihood of occurrence of a new peak of COVID-19 incidence. FINDINGS: After an initial introduction in São Paulo and Rio de Janeiro states in early March 2020, the epidemic spread to northern states and then to highly populated coastal regions and the Central-West. Municipalities with higher metrics of social development experienced earlier arrival of COVID-19 (decrease of 11·1 days [95% CI:8.9,13.2] in the time to arrival for each 10% increase in the social development index). Differences in the initial epidemic intensity (mean Rt ) were largely driven by geographic location and the date of local onset. INTERPRETATION: This study demonstrates that platforms that monitor, standardise and analyse the epidemiological data at a local level can give useful real-time insights into outbreak dynamics that can be used to better adapt responses to the current and future pandemics. FUNDING: This project was supported by a Medical Research Council UK (MRC-UK) -São Paulo Research Foundation (FAPESP) CADDE partnership award (MR/S0195/1 and FAPESP 18/14389-0).

Report 46: Factors driving extensive spatial and temporal fluctuations in COVID-19 fatality rates in Brazilian hospitals.

The SARS-CoV-2 Gamma variant spread rapidly across Brazil, causing substantial infection and death waves. We use individual-level patient records following hospitalisation with suspected or confirmed COVID-19 to document the extensive shocks in hospital fatality rates that followed Gamma's spread across 14 state capitals, and in which more than half of hospitalised patients died over sustained time periods. We show that extensive fluctuations in COVID-19 in-hospital fatality rates also existed prior to Gamma's detection, and were largely transient after Gamma's detection, subsiding with hospital demand. Using a Bayesian fatality rate model, we find that the geographic and temporal fluctuations in Brazil's COVID-19 in-hospital fatality rates are primarily associated with geographic inequities and shortages in healthcare capacity. We project that approximately half of Brazil's COVID-19 deaths in hospitals could have been avoided without pre-pandemic geographic inequities and without pandemic healthcare pressure. Our results suggest that investments in healthcare resources, healthcare optimization, and pandemic preparedness are critical to minimize population wide mortality and morbidity caused by highly transmissible and deadly pathogens such as SARS-CoV-2, especially in low- and middle-income countries. NOTE: The following manuscript has appeared as 'Report 46 - Factors driving extensive spatial and temporal fluctuations in COVID-19 fatality rates in Brazilian hospitals' at https://spiral.imperial.ac.uk:8443/handle/10044/1/91875 . ONE SENTENCE SUMMARY: COVID-19 in-hospital fatality rates fluctuate dramatically in Brazil, and these fluctuations are primarily associated with geographic inequities and shortages in healthcare capacity.

Higher risk of death from COVID-19 in low-income and non-White populations of São Paulo, Brazil.

INTRODUCTION: Little evidence exists on the differential health effects of COVID-19 on disadvantaged population groups. Here we characterise the differential risk of hospitalisation and death in São Paulo state, Brazil, and show how vulnerability to COVID-19 is shaped by socioeconomic inequalities. METHODS: We conducted a cross-sectional study using hospitalised severe acute respiratory infections notified from March to August 2020 in the Sistema de Monitoramento Inteligente de São Paulo database. We examined the risk of hospitalisation and death by race and socioeconomic status using multiple data sets for individual-level and spatiotemporal analyses. We explained these inequalities according to differences in daily mobility from mobile phone data, teleworking behaviour and comorbidities. RESULTS: Throughout the study period, patients living in the 40% poorest areas were more likely to die when compared with patients living in the 5% wealthiest areas (OR: 1.60, 95% CI 1.48 to 1.74) and were more likely to be hospitalised between April and July 2020 (OR: 1.08, 95% CI 1.04 to 1.12). Black and Pardo individuals were more likely to be hospitalised when compared with White individuals (OR: 1.41, 95% CI 1.37 to 1.46; OR: 1.26, 95% CI 1.23 to 1.28, respectively), and were more likely to die (OR: 1.13, 95% CI 1.07 to 1.19; 1.07, 95% CI 1.04 to 1.10, respectively) between April and July 2020. Once hospitalised, patients treated in public hospitals were more likely to die than patients in private hospitals (OR: 1.40%, 95% CI 1.34% to 1.46%). Black individuals and those with low education attainment were more likely to have one or more comorbidities, respectively (OR: 1.29, 95% CI 1.19 to 1.39; 1.36, 95% CI 1.27 to 1.45). CONCLUSIONS: Low-income and Black and Pardo communities are more likely to die with COVID-19. This is associated with differential access to quality healthcare, ability to self-isolate and the higher prevalence of comorbidities.

Geographic access to COVID-19 healthcare in Brazil using a balanced float catchment area approach.

The rapid spread of COVID-19 across the world has raised concerns about the responsiveness of cities and healthcare systems during pandemics. Recent studies try to model how the number of COVID-19 infections will likely grow and impact the demand for hospitalization services at national and regional levels. However, less attention has been paid to the geographic access to COVID-19 healthcare services and to hospitals' response capacity at the local level, particularly in urban areas in the Global South. This paper shows how transport accessibility analysis can provide actionable information to help improve healthcare coverage and responsiveness. It analyzes accessibility to COVID-19 healthcare at high spatial resolution in the 20 largest cities of Brazil. Using network-distance metrics, we estimate the vulnerable population living in areas with poor access to healthcare facilities that could either screen or hospitalize COVID-19 patients. We then use a new balanced floating catchment area (BFCA) indicator to estimate spatial, income, and racial inequalities in access to hospitals with intensive care unit (ICU) beds and mechanical ventilators while taking into account congestion effects. Based on this analysis, we identify substantial social and spatial inequalities in access to health services during the pandemic. The availability of ICU equipment varies considerably between cities, and it is substantially lower among black and poor communities. The study maps territorial inequalities in healthcare access and reflects on different policy lessons that can be learned for other countries based on the Brazilian case.

Zika epidemic and microcephaly in Brazil: Challenges for access to health care and promotion in three epidemic areas.

Since 2015 Brazil has experienced the social repercussions of the Zika virus epidemic, thus raising a debate about: difficulties of diagnosis; healthcare access for children with Zika Congenital Syndrome (ZCS); the search for benefits by affected families; social and gender inequalities; and a discussion on reproductive rights, among others. The objective of this article is to analyse access to specialized health services for the care of children born with ZCS in three North-eastern states of Brazil. This is an exploratory cross-sectional study which analyses recorded cases of microcephaly at the municipal level between 2015 and 2017. Most of the cases of ZCS were concentrated on the Northeast coast. Rio Grande do Norte and Paraiba had the highest incidence of microcephaly in the study period. The states of Bahia, Paraiba and Rio Grande do Norte were selected for their high incidence of microcephaly due to the Zika Virus. Socio-territorial vulnerability was stratified using access to microcephaly diagnosis and treatment indicators. The specialized care network was mapped according to State Health Secretaries Protocols. A threshold radius of 100 km was stablished as the maximum distance from municipalities centroids to specialised health care for children with microcephaly. Prenatal coverage was satisfactory in most of the study area, although availability of ultrasound equipment was uneven within states and health regions. Western Bahia had the lowest coverage of ultrasound equipment and lacked health rehabilitation services. ZCS's specialized health services were spread out over large areas, some of which were outside the affected patients' home municipalities, so displacements were expensive and very time consuming, representing an extra burden for the affected families. This study is the first to address accessibility of children with microcephaly to specialised health care services and points to the urgent need to expand coverage of these services in Brazil, especially in the northeastern states, which are most affected by the epidemic.

Disparities in travel times between car and transit: Spatiotemporal patterns in cities.

Cities worldwide are pursuing policies to reduce car use and prioritise public transit (PT) as a means to tackle congestion, air pollution, and greenhouse gas emissions. The increase of PT ridership is constrained by many aspects; among them, travel time and the built environment are considered the most critical factors in the choice of travel mode. We propose a data fusion framework including real-time traffic data, transit data, and travel demand estimated using Twitter data to compare the travel time by car and PT in four cities (São Paulo, Brazil; Stockholm, Sweden; Sydney, Australia; and Amsterdam, the Netherlands) at high spatial and temporal resolutions. We use real-world data to make realistic estimates of travel time by car and by PT and compare their performance by time of day and by travel distance across cities. Our results suggest that using PT takes on average 1.4-2.6 times longer than driving a car. The share of area where travel time favours PT over car use is very small: 0.62% (0.65%), 0.44% (0.48%), 1.10% (1.22%) and 1.16% (1.19%) for the daily average (and during peak hours) for São Paulo, Sydney, Stockholm, and Amsterdam, respectively. The travel time disparity, as quantified by the travel time ratio [Formula: see text] (PT travel time divided by the car travel time), varies widely during an average weekday, by location and time of day. A systematic comparison between these two modes shows that the average travel time disparity is surprisingly similar across cities: [Formula: see text] for travel distances less than 3 km, then increases rapidly but quickly stabilises at around 2. This study contributes to providing a more realistic performance evaluation that helps future studies further explore what city characteristics as well as urban and transport policies make public transport more attractive, and to create a more sustainable future for cities.

Análise de dimensões do acesso à saúde das crianças com Síndrome Congênita de Zika (SCZ) na Região Metropolitana do Rio de Janeiro / Dimensional analysis of access to health of children with Congenital Zika Syndrome (CZS) in the Metropolitan Region of Rio de Janeiro

Resumo Desde 2015 a população brasileira vive com as repercussões da epidemia de Zika, levantando o debate sobre as dificuldades de diagnóstico e acesso aos cuidados para crianças com Síndrome Congênita do Zika. As regiões Nordeste e Sudeste foram as mais atingidas, desafiando-nos a caracterizar o acesso à saúde das crianças portadoras da Síndrome Congênita do Zika nessas regiões. O objetivo deste artigo é analisar a disponibilidade e a acessibilidade dos serviços de saúde para a reabilitação das crianças com Síndrome Congênita do Zika na Região Metropolitana do Rio de Janeiro. A metodologia consistiu no mapeamento dos casos de Síndrome Congênita do Zika entre 2015 e 2017 na Região Metropolitana do Rio de Janeiro por bairros de residência e relacionados com a localização das unidades de reabilitação indicadas no Protocolo da Secretaria de Estado de Saúde do Rio de Janeiro. Como resultado foram identificados 202 casos de Síndrome Congênita do Zika na Região Metropolitana do Rio de Janeiro no período de 2015 a 2017. A região teve 85% de todos os casos do estado do Rio de Janeiro, o município do Rio de Janeiro concentrou 63% dos casos. A acessibilidade nesse município é a melhor se comparada com os demais da região metropolitana, dado que é a capital do estado e concentra grande parte dos serviços especializados em saúde materno-infantil.

Abstract Since 2015, the Brazilian population has lived with the repercussions of the Zika epidemic, raising the debate on the difficulties of diagnosis and access to care for children with Congenital Zika Syndrome (CZS). The Northeast and Southeast regions were the hardest hit, challenging us to characterize the access to health of children with ZCS in these regions. The aim of this paper is to analyse the availability and accessibility of health services for the rehabilitation of children with CZS in the Rio de Janeiro Metropolitan Region (RMRJ). The methodology consisted of mapping the cases of CZS between 2015 and 2017 in RJRM by neighbourhoods of residence and related to the location of rehabilitation units indicated in the Protocol of the Rio de Janeiro State Secretariat of Health (SES/RJ). As a result, 202 cases of CZS were identified in the RMRJ from 2015 to 2017. The RMRJ had 85% of all cases in the state of Rio de Janeiro, the municipality of Rio de Janeiro concentrated 63% of the cases. Accessibility in this municipality is better compared to the others in the RMRJ, as it is the state capital and concentrates most of the specialized services in maternal and child health.

Mobilidade urbana e o acesso ao Sistema Único de Saúde para casos suspeitos e graves de Covid-19 nas vinte maiores cidades do Brasil / Nota Técnica n. 14 (Dirur) : Mobilidade urbana e o acesso ao Sistema Único de Saúde para casos suspeitos e graves de Covid-19 nas vinte maiores cidades do Brasil

A iminência da crise do sistema de saúde causada pela Covid-19 exige inúmeras ações emergenciais. Entre estas, é essencial para o planejamento dos serviços de saúde ter um diagnóstico de quais áreas das cidades têm menos acesso a equipamentos de saúde, e quais são os hospitais que poderão ter maior sobrecarga de demanda por internações. Esta nota técnica tem como objetivos: (1) estimar quantas são e onde moram as pessoas mais vulneráveis com maior dificuldade de acessar equipamentos de saúde; e (2) apontar quais são os estabelecimentos de saúde que poderão ter maior estrangulamento de demanda, considerando-se sua capacidade de oferta de leitos de unidades de tratamento intensivo (UTIs). Este trabalho analisou a capacidade de suporte do SUS, apresentando estimativas da quantidade de leitos de UTI/respiradores por pessoa de cada hospital nos maiores municípios do Brasil. Os resultados apontam que os maiores municípios do Brasil têm um número de leitos de UTI adulto com respiradores disponíveis ao SUS muito próximo do mínimo desejável, segundo o Ministério da Saúde. No entanto, esse valor pode ficar muito abaixo do necessário para lidar com um grande crescimento da demanda de internações, mesmo caso os cenários mais otimistas de propagação da Covid-19 no Brasil se confirmem. Os resultados apontam uma situação ainda mais preocupante nas periferias dos grandes centros urbanos, onde, via de regra, a baixa oferta de equipamentos de saúde, combinada com piores condições de urbanização e de renda, aumentam o potencial de propagação da Covid-19 diante de uma baixa capacidade de atendimento do sistema de saúde. Esses resultados podem ajudar a identificar quais unidades de saúde poderiam receber aportes de recursos suplementares para ampliação de sua capacidade. Uma análise mais detalhada desses resultados poderia apontar também quais são os bairros das cidades onde a construção de hospitais de campanha seria mais eficaz quanto ao aumento do acesso da população aos serviços de saúde.

Desigualdades socioespaciais de acesso a oportunidades nas cidades brasileiras ­ 2019 / Texto para Discussão (TD) 2535 : Desigualdades socioespaciais de acesso a oportunidades nas cidades brasileiras ­ 2019

Um dos principais objetivos das políticas de transporte urbano é facilitar o acesso das pessoas a oportunidades de emprego, serviços de saúde e educação, atividades culturais e de lazer. No entanto, os estudos e as políticas de mobilidade urbana no Brasil costumam dar ênfase aos desafios de reduzir congestionamentos e o tempo que as pessoas gastam no trânsito, ao passo que dedicam pouca atenção ao tema da acessibilidade urbana. Este estudo apresenta os primeiros resultados do Projeto Acesso a Oportunidades, e faz um retrato das desigualdades de acesso a oportunidades nas maiores cidades brasileiras no ano de 2019, com estimativas de acesso a empregos, serviços de saúde e educação. Nesta edição, o estudo inclui estimativas de acessibilidade por modos de transporte ativo (a pé e de bicicleta) para as vinte maiores cidades do país, e por transporte público para sete grandes cidades (São Paulo, Rio de Janeiro, Belo Horizonte, Recife, Fortaleza, Porto Alegre e Curitiba). O projeto combina dados de registros administrativos, pesquisas amostrais, dados de imagens de satélite e de mapeamento colaborativo, para se calcular os níveis de acessibilidade em alta resolução espacial, e desagregados por grupos socioeconômicos segundo nível de renda e cor/raça. Os resultados revelam dois padrões gerais. Em todas as vinte cidades estudadas, a concentração de atividades nas áreas urbanas centrais aliada à performance/conectividade das redes de transporte leva a áreas de alta acessibilidade próximas ao centro das cidades, em contraste com regiões de periferia marcadas por desertos de oportunidades. Ainda, os resultados apontam que a população branca e de alta renda tem em média mais acesso a oportunidades de trabalho, saúde e educação do que a população negra e pobre em todas as cidades estudadas, independentemente do meio de transporte considerado. Os resultados e bases de dados do Projeto Acesso a Oportunidades são disponíveis publicamente, criando rico material que pode ser utilizado para guiar o planejamento e avaliação de políticas públicas que promovam cidades sustentáveis e inclusivas.

Determinants of Stroke in Brazil: A Cross-Sectional Multivariate Approach from the National Health Survey.

OBJECTIVE: The objective of this study was to investigate the association between biological-health, socioeconomics, and behavioral determinants and stroke by evaluating the risk of stroke in the presence of each or all determinants grouped in a multivariate model. METHODS: This study is a transversal secondary data analysis of the Brazilian National Health Survey, released by the Brazilian Institute of Geography and Statistics. The prevalence, prevalence ratios, and confidence intervals were calculated for the main outcome. A multivariate regression model was applied, with the stroke as outcome and all other variables with a P value of .20 or lower in the univariate analysis included as explanatory variables to adjust for potential confounders and effect modifiers. RESULTS: The mean age was 43.3 ± 16.6 years, ranging from 18 to 101 years. The prevalence of hypertension was 21.4%, and with regard to lifestyle habits, it was observed that 20.0% had smoked but stopped and 29.7% practiced physical activity in the last 30 days. The regression model showed that the odds ratio in the final model was weighted, with low schooling, smoking habit, overweight, low physical activity practice, diabetes, and hypertension being significantly associated with stroke. CONCLUSION: The multivariate model showed that the chance of stroke is high, both combined or isolated.

Determinantes do emprego secundário e informalidade: evidências adicionais para o mercado de trabalho brasileiro / Determinants of secondary employment and informality: additional evidence for the Brazilian labor market / Determinantes del empleo secundario e informalidad: evidencias adicionales para el mercado de trabajo brasileño

O objetivo deste estudo é analisar os fatores que determinam a escolha de um indivíduo por um emprego secundário e como tal decisão está relacionada com a informalidade. Para tanto, a partir dos dados da Pesquisa Nacional por Amostra de Domicílios (PNAD) contínua, é estimado um modelo logit de efeitos aleatórios para verificar os fatores que influenciam nesta decisão de inserção. Os resultados apontam que o rendimento do trabalho principal, a escolaridade e a informalidade no emprego principal influenciam positivamente na decisão dos trabalhadores em ingressar em um emprego secundário.

This study aims to analyze the factors that determine an individual's choice of having secondary employment and how this decision is related to informality. To that end, based on data from "Pesquisa Nacional por Amostra de Domicílios (PNAD) contínua", we estimate a random effects Logit model to verify factors influencing this decision of insertion. Results indicate that the main work income, schooling and informality in the main employment have a positive influence on the worker's decision to seek secondary employment.

Para ello, a partir de los datos de la Pesquisa Nacional por Amostra de Domicílios (PNAD) contínua, se estima un modelo logit de efectos aleatorios para verificar los factores que influyen en esta decisión de inserción laboral. Los resultados apuntan a que el rendimiento del trabajo principal, la escolaridad y la informalidad en el empleo principal influyen positivamente en la decisión de los trabajadores de obtener en un empleo secundario.

Socioeconomic and regional differences in active transportation in Brazil.

OBJECTIVE: To present national estimates regarding walking or cycling for commuting in Brazil and in 10 metropolitan regions. METHODS: By using data from the Health section of 2008's Pesquisa Nacional por Amostra de Domicílio (Brazil's National Household Sample Survey), we estimated how often employed people walk or cycle to work, disaggregating our results by sex, age range, education level, household monthly income per capita, urban or rural address, metropolitan regions, and macro-regions in Brazil. Furthermore, we estimated the distribution of this same frequency according to quintiles of household monthly income per capita in each metropolitan region of the country. RESULTS: A third of the employed men and women walk or cycle from home to work in Brazil. For both sexes, this share decreases as income and education levels rise, and it is higher among younger individuals, especially among those living in rural areas and in the Northeast region of the country. Depending on the metropolitan region, the practice of active transportation is two to five times more frequent among low-income individuals than among high-income individuals. CONCLUSIONS: Walking or cycling to work in Brazil is most frequent among low-income individuals and the ones living in less economically developed areas. Active transportation evaluation in Brazil provides important information for public health and urban mobility policy-making. OBJETIVO: Apresentar estimativas nacionais sobre o deslocamento a pé ou de bicicleta no trajeto casa-trabalho no Brasil e em 10 de suas regiões metropolitanas. MÉTODOS: Utilizando dados do Suplemento sobre Saúde da Pesquisa Nacional por Amostra de Domicílios de 2008, estimamos a frequência de pessoas empregadas que se deslocam a pé ou de bicicleta no trajeto casa-trabalho estratificada por sexo, e segundo faixa etária, escolaridade, renda domiciliar per capita, residência em área urbana ou rural, regiões metropolitanas e macrorregiões do país. Adicionalmente, estimamos a distribuição da mesma frequência segundo quintos da distribuição da renda domiciliar per capita em cada região metropolitana. RESULTADOS: Um terço dos homens e mulheres empregados desloca-se a pé ou de bicicleta de casa para o trabalho no Brasil. Em ambos os sexos, esta proporção diminui com o aumento da renda e da escolaridade e é maior entre os mais jovens, entre os que residem em área rural e naqueles residentes na região Nordeste. A depender da região metropolitana, a prática de deslocamento ativo entre os mais pobres é de duas a cinco vezes maior do que entre os mais ricos. CONCLUSÕES: O deslocamento a pé ou de bicicleta para o trabalho no Brasil é mais frequente entre os mais pobres e entre pessoas que vivem em áreas e regiões economicamente menos desenvolvidas. A avaliação do deslocamento ativo no País traz informações importantes para a discussão de políticas públicas de mobilidade.

Socioeconomic and health conditions associated with quality of life of elderly quilombolas / Condiciones socioeconómicas y de salud asociadas con la calidad de vida de ancianos quilombolas / Condições socioeconômicas e de saúde associadas à qualidade de vida de idosos quilombolas

ABSTRACT This study aimed to identify the socioeconomic and health conditions associated with quality of life of elderly quilombolas. Cross-sectional, epidemiological and census study, conducted with 427 elderly individuals of a quilombola population enrolled in Family Health Strategies of 17 quilombas communities in Vitória da Conquista, Bahia, four districts of the region. Data collection was performed using tools and analyzed based on descriptive statistics and Spearman correlation (rsp). The factors associated with some areas of Quality of Life and the General Quality of Life Index included the per capita income, the self-assessment of health status and the classification of depression cases, which most strongly affected the quality of life of the elderly quilombolas investigated. The expanded access to health services and the integrality of health care for this group are essential, particularly involving Family Health Teams.

Depending on the metropolitan region, the practice of active transportation is two to five times more frequent among low-income individuals than among high-income individuals. CONCLUSIONS Walking or cycling to work in Brazil is most frequent among low-income individuals and the ones living in less economically developed areas. Active transportation evaluation in Brazil provides important information for public health and urban mobility policy-making

RESUMO OBJETIVO Apresentar estimativas nacionais sobre o deslocamento a pé ou de bicicleta no trajeto casa-trabalho no Brasil e em 10 de suas regiões metropolitanas. MÉTODOS Utilizando dados do Suplemento sobre Saúde da Pesquisa Nacional por Amostra de Domicílios de 2008, estimamos a frequência de pessoas empregadas que se deslocam a pé ou de bicicleta no trajeto casa-trabalho estratificada por sexo, e segundo faixa etária, escolaridade, renda domiciliar per capita, residência em área urbana ou rural, regiões metropolitanas e macrorregiões do país. Adicionalmente, estimamos a distribuição da mesma frequência segundo quintos da distribuição da renda domiciliar per capita em cada região metropolitana. RESULTADOS Um terço dos homens e mulheres empregados desloca-se a pé ou de bicicleta de casa para o trabalho no Brasil. Em ambos os sexos, esta proporção diminui com o aumento da renda e da escolaridade e é maior entre os mais jovens, entre os que residem em área rural e naqueles residentes na região Nordeste. A depender da região metropolitana, a prática de deslocamento ativo entre os mais pobres é de duas a cinco vezes maior do que entre os mais ricos. CONCLUSÕES O deslocamento a pé ou de bicicleta para o trabalho no Brasil é mais frequente entre os mais pobres e entre pessoas que vivem em áreas e regiões economicamente menos desenvolvidas. A avaliação do deslocamento ativo no País traz informações importantes para a discussão de políticas públicas de mobilidade.

[Association between psychosocial aspects of work and quality of life among motorcycle taxi drivers]. / Associação entre aspectos psicossociais do trabalho e qualidade de vida de mototaxistas.

This study aimed to evaluate the quality of life of motorcycle taxi drivers and the association with psychosocial characteristics of their work. This was a cross-sectional epidemiological study with a sample of 400 motorcycle taxi drivers in Jequié, Bahia State, Brazil. The study used a form containing demographic and socioeconomic data, WHO Quality of Life-Bref Questionnaire (WHOQOL-Bref), and the Job Content Questionnaire (JCQ). Motorcycle taxi drivers with greater decision-making control over their work showed better self-rated quality of life in the psychological domain; those with high psychological demands presented better self-rated quality of life in the social relations and environmental domains; those with high strain and active work showed better self-rated quality of life in the social and environmental domains. The psychosocial work environment and especially decision-making autonomy were thus important determinants of self-rated quality of life in this group of motorcycle taxi drivers.

Associação entre aspectos psicossociais do trabalho e qualidade de vida de mototaxistas / Association between psychosocial aspects of work and quality of life among motorcycle taxi drivers / Asociación entre aspectos psicosociales del trabajo y calidad de vida de mototaxistas

Este estudo objetivou avaliar a qualidade de vida de mototaxistas e sua relação com os aspectos psicossociais do trabalho. Estudo epidemiológico, transversal, realizado com 400 mototaxistas do Município de Jequié, Bahia, Brasil. Utilizou-se um formulário contendo dados sociodemográficos, o WHO Quality of Life-Bref Questionnaire (WHOQOL-Bref) e o Job Content Questionnaire (JCQ). Os resultados evidenciaram que mototaxistas com alto controle sobre o trabalho apresentaram melhor percepção de qualidade de vida no domínio psicológico; os que possuem alta demanda psicológica apresentaram melhor percepção de qualidade de vida nos domínios relações sociais e meio ambiente; aqueles com alta exigência e com trabalho ativo apresentaram melhor percepção de qualidade de vida nos domínios relações sociais e meio ambiente. Assim, o ambiente psicossocial do trabalho, e, especialmente, o controle sobre o trabalho, são importantes determinantes da percepção da qualidade de vida dos mototaxistas.

[Mental health policies in Santa Catarina in the 1970s: the vanguard of Brazilian psychiatry?]. / Politicas de saude mental em Santa Catarina nos anos 1970: vanguarda na psiquiatria brasileira?

Highlighting the social and economic context, the article examines the changes in psychiatric care in the state of Santa Catarina from 1971 through 1975. Guided by experts from the Pan American Health Organization, the state government devised a mental health policy that was based on U.S. experiences in preventive and community psychiatry under the Kennedy administration (1961-1963) and that was in tune with the guidelines laid out by Brazil's National Social Security Division (Divisão Nacional de Previdência Social). As a product of qualitative research based on interviews with professionals involved in the development of these initiatives in the 1970s, the article discusses the background to the 1980s and 1990s psychiatric reform in Brazil and reflects on the historical role of these initiatives in Santa Catarina.
