Thyroid Cancer Incidence and Mortality by Socioeconomic Level in the State of São Paulo, Brazil 2001-2017.

OBJECTIVE: Thyroid cancer is rising largely due to greater detection of indolent or slow-growing tumors; we sought to compare the incidence and mortality profiles of thyroid cancer in the State of São Paulo by socioeconomic status (SES). METHODS: Data on thyroid cancer cases diagnosed from 2003 to 2017 in the Barretos Region and from 2001 to 2015 in the municipality of São Paulo were obtained from the respective cancer registries. Corresponding death data were obtained from a Brazilian public government database. Age-standardized rates were calculated and presented as thematic maps. The rates were also calculated by SES and spatial autocorrelation was assessed by global and local indices. RESULTS: There were 419 cases of thyroid cancer and 21 deaths in Barretos, contrasting with the highly populated São Paulo, with 30 489 cases and 673 deaths. The overall incidence rates in São Paulo (15.9) were three times higher than in Barretos (5.7), while incidence rates in women were close to five times higher in Barretos and four times higher in São Paulo than in men. Mortality rates were, in relative terms, very low in both regions. A clear stepwise gradient of increasing thyroid cancer incidence with increasing SES was observed in São Paulo, with rates in very high SES districts four times those of low SES (31.6 vs 8.1). In contrast, the incidence rates in Barretos presented little variation across SES levels. CONCLUSION: Thyroid cancer incidence varied markedly by SES in São Paulo, with incidence rates rising with increasing socioeconomic index. Overdiagnosis is likely to account for a large proportion of the thyroid cancer burden in the capital.

Bayesian modeling of hematologic cancer and vehicular air pollution among young people in the city of São Paulo, Brazil.

Traffic-related air pollution is being associated with hematologic cancer in young individuals. This study performed a spatial analysis of the hematologic cancer incidence and mortality among younger people, using a Bayesian approach, to associate with traffic density in the city of São Paulo, Brazil. Two databases were employed: incidence (2002-2011) and mortality (2002-2013). The relationships between the cases of hematologic cancer and the covariates - traffic density, the Municipal Human Development Index (MHDI), and population density - were evaluated using a Besag-York-Mollié ecological model with relative risks (RRs) estimates. Per 1-unit standard-deviation increase in traffic density, in the MHDI, and in population density, the RR for the incidence was 1.06 (95% CI: 0.97-1.14), 1.28 (95% CI: 1.16-1.42), and 1.01 (95% CI: 0.94-1.08), respectively. For mortality, no covariates were considered risk factors. Our findings suggest significant association between living in regions with better socioeconomic conditions, where traffic density is usually higher, and risk of hematologic cancer in younger people.

Incidence and mortality for respiratory cancer and traffic-related air pollution in São Paulo, Brazil.

BACKGROUND: Multiple lines of evidence have associated exposure to ambient air pollution with an increased risk of respiratory malignancies. However, there is a dearth of evidence from low-middle income countries, including those within South America, where the social inequalities are more marked. OBJECTIVES: To quantify the association between exposures to traffic related air pollution and respiratory cancer incidence and mortality within São Paulo, Brazil. Further, we aim to investigate the role of socioeconomic status (SES) upon these outcomes. METHODS: Cancer incidence between 2002 and 2011 was derived from the population-based cancer registry. Mortality data (between 2002 and 2013) was derived from the Municipal Health Department. A traffic density database and an annual nitrogen dioxide (NO2) land use regression model were used as markers of exposure. Age-adjusted Binomial Negative Regression models were developed, stratifying by SES and gender. RESULTS: We observed an increased rate of respiratory cancer incidence and mortality in association with increased traffic density and NO2 concentrations, which was higher among those regions with the lowest SES. For cancer mortality and traffic exposure, those in the most deprived region, had an incidence rate ratio (IRR) of 2.19 (95% CI: 1.70, 2.82) when comparing the highest exposure centile (top 90%) to the lowest (lowest 25%). By contrast, in the least deprived area, the IRR for the same exposure contrast was.1.07 (95% CI: 0.95, 1.20). For NO2 in the most deprived regions, the IRR for cancer mortality in the highest exposed group was 1.44 (95% CI: 1.10, 1.88) while in the least deprived area, the IRR for the highest exposed group was 1.11 (95% CI: 1.01, 1.23). CONCLUSIONS: Traffic density and NO2 were associated with an increased rate of respiratory cancer incidence and mortality in São Paulo. Residents from poor regions may suffer more from the impact of traffic air pollution.

Sociodemographic, anthropometric and behavioural risk factors for ultra-processed food consumption in a sample of 2-9-year-olds in Brazil.

OBJECTIVE: The present study aimed to identify food patterns among 2-9-year-olds and investigate sociodemographic, anthropometric and behavioural predictors of less healthy dietary patterns. DESIGN: Cross-sectional study. Parents of 2-9-year-olds completed an FFQ and factor analysis was applied to identify dietary patterns. Parents also completed questionnaires assessing sociodemographic, anthropometric and behavioural characteristics of parents and children, including parental feeding practices. SETTING: Participants were recruited from private schools of Campinas and São Paulo, SP, Brazil, between April and June 2014. SUBJECTS: Parents of 2-9-year-olds (n 929). RESULTS: Two dietary patterns emerged: 'traditional food' and 'ultra-processed food'. Lower maternal education (OR=2·05, P=0·010) and higher maternal weight status (OR=1·43, P=0·044) were associated with a greater likelihood of the ultra-processed food pattern. Lower perceived parental responsibility for adequacy of food group intake (OR=2·41, P=0·020), and lower scores on the parental feeding practices of 'Healthy Eating Guidance' (OR=1·83, P<0·001) and 'Monitoring' (OR=2·52, P<0·001), were also associated with the presence of this pattern, as was higher child's screen use during mealtimes (OR=1·61, P=0·004). CONCLUSIONS: The present study is the first to evaluate associations between less healthy dietary patterns of Brazilian 2-9-year-olds and parental feeding practices. Our findings highlight sociodemographic, anthropometric and behavioural factors within families that could be used to target tailored policies to at-risk populations.

Relationships between parent feeding behaviors and parent and child characteristics in Brazilian preschoolers: a cross-sectional study.

BACKGROUND: Eating habits formed in early childhood are influenced by parental feeding behaviors, warranting investigation of predictors and correlates of parent feeding. We aimed to describe relationships between parental feeding practices and parent and child characteristics in a sample of Brazilian preschoolers. METHODS: Four hundred and two parents of preschoolers enrolled in private schools of São Paulo and Campinas, Brazil, completed a Brazilian version of the Comprehensive Feeding Practices Questionnaire, as well as questions about parental attitudes, child food intake, other obesity-associated behaviors, and socioeconomic and demographic characteristics. We ran bivariate logistic regression models examining associations between independent variables and each feeding practice. Next, we ran multiple logistic regression models predicting each parental feeding practice. RESULTS: Greater 'Restriction for Weight Control' and 'Restriction for Health' were associated with lower maternal education (OR = 2.42 (CI 95% 1.07-5.48) and 2.79 (CI 95% 1.25-6.22), respectively), and with higher concern about child overweight (OR = 2.46, CI 95% 1.64-3.69 for 'Restriction for Weight Control', only), while greater 'Pressure' was associated with greater concern about child underweight (OR = 2.30, CI 95% 1.53-3.47) and lower maternal BMI (OR = 0.94, CI 95% 0.88-1.00). Greater use of 'Emotion Regulation/ Food as Reward' was associated with lower maternal education (OR = 2.22, CI 95% 1.05-4.71). In analyses of positive feeding practices, lesser use of 'Healthy Eating Guidance' and 'Monitoring' was associated with greater intake of less healthy foods in children (OR = 1.53 (CI 95% 1.01-2.32) and OR = 1.94 (CI 95% 1.27-2.97), respectively), and greater use of screen devices (OR = 1.59 (CI 95% 1.04-2.44) and OR = 1.57 (CI 95% 1.03-2.39), respectively). Lesser use of 'Healthy Eating Guidance' was additionally associated with higher maternal BMI (OR = 1.09, CI 95% 1.03-1.16), and lesser use of 'Monitoring' with lesser perceived parent responsibility for child feeding (OR = 1.68, CI 95% 1.12-2.52). CONCLUSIONS: Our results demonstrate diverse socioeconomic, anthropometric and behavioral correlates of parent feeding in a large Brazilian sample of parents of preschoolers.

Validation of the comprehensive feeding practices questionnaire in parents of preschool children in Brazil.

BACKGROUND: Recent national surveys in Brazil have demonstrated a decrease in the consumption of traditional food and a parallel increase in the consumption of ultra-processed food, which has contributed to a rise in obesity prevalence in all age groups. Environmental factors, especially familial factors, have a strong influence on the food intake of preschool children, and this has led to the development of psychometric scales to measure parents' feeding practices. The aim of this study was to test the validity of a translated and adapted Comprehensive Feeding Practices Questionnaire in a sample of Brazilian preschool-aged children enrolled in private schools. METHODS: A transcultural adaptation process was performed in order to develop a modified questionnaire (43 items). After piloting, the questionnaire was sent to parents, along with additional questions about family characteristics. Test-retest reliability was assessed in one of the schools. Factor analysis with oblique rotation was performed. Internal reliability was tested using Cronbach's alpha and correlations between factors, discriminant validity using marker variables of child's food intake, and convergent validity via correlations with parental perceptions of perceived responsibility for feeding and concern about the child's weight were also performed. RESULTS: The final sample consisted of 402 preschool children. Factor analysis resulted in a final questionnaire of 43 items distributed over 6 factors. Cronbach alpha values were adequate (0.74 to 0.88), between-factor correlations were low, and discriminant validity and convergent validity were acceptable. CONCLUSIONS: The modified CFPQ demonstrated significant internal reliability in this urban Brazilian sample. Scale validation within different cultures is essential for a more comprehensive understanding of parental feeding practices for preschoolers.

Evolution of hospital spending with drug-related psychiatric hospital admissions. / Evolução dos gastos hospitalares com internações psiquiátricas por drogas.

OBJECTIVE: To analyse the trend of expenditure on drug-related psychiatric hospital admissions in Maringá, Paraná, Brazil, from 1999 to 2012. METHOD: Ecological time series research with secondary data from the hospital information system of the unified health system ("SIH-SUS"). The records of admissions with a main diagnosis of drug abuse were used to calculate average expenditure. Chapter V of the ICD-10 was used to classify the most frequent diagnoses, namely abuse of alcohol, cannabis, cocaine, and psychoactive substances. The trend was expressed using a polynomial regression model. RESULTS: Average expenditure showed an increasing trend for cocaine and other psychoactive substances, and a decreasing trend for cannabis. Average expenditure for illicit drugs increased significantly. CONCLUSION: The scarcity of economic studies on this subject calls for national studies that address expenditure with drug-related hospital admission to promote the implementation of a psychosocial, outpatient and hospital care network in accord with public healthcare expenditure.

[Development and validation of the Family Vulnerability Index to Disability and Dependence (FVI-DD)]. / Desenvolvimento e validação do índice de vulnerabilidade de famílias a incapacidades e dependência (IVF-ID).

This exploratory, descriptive, cross-sectional, and quantitative study aimed to develop and validate an index of family vulnerability to disability and dependence (FVI-DD). This study was adapted from the Family Development Index, with the addition of social and health indicators of disability and dependence. The instrument was applied to 248 families in the city of Sao Paulo, followed by exploratory factor analysis. Factor validation was performed using the concurrent and discriminant validity of the Lawton scale and Katz Index. The descriptive level adopted for the study was p < 0.05. The final vulnerability index comprised 50 questions classified into seven factors contemplating social and health dimensions, and this index exhibited good internal consistency (Cronbach's alpha = 0.82). FVI-DD was validated using both the Lawton scale and Katz Index. We conclude that FVI-DD can accurately and reliably assess family vulnerability to disability and dependence.

COVID-19 Mortality among Hospitalized Patients: Survival, Associated Factors, and Spatial Distribution in a City in São Paulo, Brazil, 2020.

The aims of this study were to analyze patient survival, identify the prognostic factors for patients with COVID-19 deaths considering the length of hospital stay, and evaluate the spatial distribution of these deaths in the city of Jundiaí, São Paulo, Brazil. We examined prognostic variables and survival rates of COVID-19 patients hospitalized at a reference hospital in Jundiaí, Brazil. A retrospective cohort of hospitalized cases from April to July of 2020 was included. Descriptive analysis, Kaplan-Meier curves, univariate and multivariate Cox regression, and binary logistic regression models were used. Among the 902 reported and confirmed cases, there were 311 deaths (34.5%). The median survival was 27 days, and the mean for those discharged was 46 days. Regardless of the length of hospital stay, desaturation, immunosuppression, age over 60, kidney disease, hypertension, lung disease, and hypertension were found to be independent predictors of death in both Cox and logistic regression models.

Cancer inequalities in incidence and mortality in the State of São Paulo, Brazil 2001-17.

BACKGROUND: Cancer disparities exist between and within countries; we sought to compare cancer-specific incidence and mortality according to area-level socioeconomic status (SES) in the State of São Paulo, Brazil. METHODS: Cancer cases diagnosed 2003-2017 in the Barretos region and 2001-2015 in the municipality of São Paulo were obtained from the respective cancer registries. Corresponding cancer deaths were obtained from a Brazilian public government database. Age-standardized rates for all cancer combined and the six most common cancers were calculated by SES quartiles. RESULTS: There were 14,628 cancer cases and 7513 cancer deaths in Barretos, and 472,712 corresponding cases and 194,705 deaths in São Paulo. A clear SES-cancer gradient was seen in São Paulo, with rates varying from 188.4 to 333.1 in low to high SES areas, respectively. There was a lesser social gradient for mortality, with rates in low to high SES areas ranging from 86.4 to 98.0 in Barretos, and from 99.2 to 100.1 in São Paulo. The magnitude of the incidence rates rose markedly with increasing SES in São Paulo city for colorectal, lung, female breast, and prostate cancer. Conversely, both cervical cancer incidence and mortality rose with lower levels of SES in both regions. CONCLUSIONS: A clear SES association was seen for cancers of the prostate, female breast, colorectum, and lung for São Paulo. This study offers a better understanding of the cancer incidence and mortality profile according to SES within a highly populated Brazilian state.

Survival inequalities in head and neck cancers: A hospital-based cohort study.

BACKGROUND: We investigated whether the socioeconomic status (SES) influenced survival rates in oropharynx cancers (OPC), oral cavity cancers (OCC), and larynx cancers (LC) in Brazilian patients. METHODS: This hospital-based cohort study assessed the age-standardized 5-year relative survival (RS) using the Pohar Perme estimator. RESULTS: Overall, we identified 37 191 cases, and 5-year RS were 24.4%, 34.1%, and 44.9% in OPC, OCC, and LC, respectively. In multiple Cox regression, the highest risk of death occurred in the most vulnerable social strata for all subsites-that is, illiterates or patients relying on publicly funded healthcare services. Disparities increased over time by 34.9% in OPC due to the rising of survival rates in the highest SES, whereas they reduced by 10.2% and 29.6% in OCC and LC. CONCLUSIONS: The potential inequities were more significant for OPC than for OCC and LC. It is urgent to tackle social disparities to improve prognoses in highly unequal countries.

The impact of late diagnosis on the survival of patients following their first AIDS-related hospitalization in Belo Horizonte, Brazil.

The purpose of this study is to estimate the survival probability of patients following their first admission for the treatment of AIDS to an infectious disease reference hospital in Belo Horizonte, Brazil, during 2005. Study subjects were monitored during a 12-month period to identify factors associated with survival probability. Late diagnosis was recorded among many of the 250 study subjects: almost half (44.8%) were diagnosed less than 30 days prior to or during their hospitalization. A high mortality rate was also detected: 39.6% of the subjects died during the 12 months of monitoring. The cumulative survival probability of the cohort group was estimated at 68.0% after 3 months and at 61.2% after 12 months. However, certain patient subgroups analyzed had even lower cumulative survival probabilities after 12 months of monitoring: if diagnosed during hospitalization, it was estimated at only 48.0% and those with no record of antiretroviral treatment had a 48.5% cumulative survival probability. Patients with severe anemia had the lowest survival probability, similar among the two lymphocyte count groups (<1000 mm(3) and ≥1000 mm(3)), the former with a 45.5% survival probability and the latter with a 46.7% one. The proportional death risk was 2.5-fold higher for men residing in other area than the capital city of the State of Minas Gerais and greater metropolitan region when compared with women residing there. The findings of this study highlight the importance of early diagnosis for predicting patient survival and reinforce the necessity of facilitating HIV diagnosis.

Factors associated with work ability and intention to leave nursing profession: a nested case-control study.

This study aims to identify factors associated with impaired work ability and intention to leave the nursing profession. This is a case-control nested within a cross-sectional study. Samples were randomly selected for work ability (475 controls and 158 cases) and intention to leave profession (454 controls and 151 cases). Data on demographic, lifestyle, occupational features, work environment, work ability and intention to leave profession were collected. Multiple logistic regression analysis was performed. Factors associated with work ability impairment were: risk for moderate (OR=1.28) and high (OR=2.26) job strain, effort-reward imbalance (OR=2.82), high overcommitment (OR=1.77), situations that may contribute to musculoskeletal pain/injury with moderate (OR=1.82) or high (OR=2.58) exposures, degree level (OR=2.13) or elementary/high school level (OR=1.67), and low physical activity (OR=1.74). Age of 31-40 years (OR=0.26) and ≥41 years (OR=0.27) were protective factors. Factors associated with intention to leave profession were: high risk for job strain (OR=1.81), effort-reward imbalance (OR=3.25), situations that may contribute to musculoskeletal pain/injury with high exposure (OR=1.54), and insomnia symptoms (OR=2.72). Age >40 years was a protective factor (OR=0.50). Individual characteristics and occupational conditions were associated with work ability impairment and intention to leave profession. Measures to improve working conditions and individual resources were recommended.

Religiosity as a potential mediator for violence in childhood and adulthood: results from a Brazilian nationally representative survey.

OBJECTIVES: Although previous studies have investigated the role of religiosity in violence outcomes, there is a lack of studies including this aspect as a mediator for violence in childhood and adulthood. This study aimed to investigate the relationship between religiosity and violence in childhood, as well as the possible mediating role of religiosity between suffering violence in childhood and suffering and/or perpetrating violence in adulthood. DESIGN: Cross-sectional population-based study carried out from November 2011 to March 2012. SETTING: Face-to-face surveys (at participants' homes) were performed in a Brazilian nationally representative sample. PARTICIPANTS: A total of 3378 adults (aged 19 years and above) were included. PRIMARY AND SECONDARY OUTCOMES MEASURES: The association between suffering violence in childhood and religiosity, and the mediating role of religiosity between childhood and adulthood violence were analysed using logistic regression models. RESULTS: Religiosity was associated with childhood violence, showing that those who suffered less violence in childhood were more religious in adulthood and considered religion more important in their lives. However, while there was a significant association between suffering violence during childhood and suffering and/or perpetrating violence in adulthood, religiosity did not mediate this relationship. CONCLUSIONS: Although religious individuals self-reported less violence suffered in childhood, religiosity did not show evidence of being a potential mediator for childhood and adulthood violence (experienced and/or perpetrated). These results could help researchers explore this phenomenon, and aid health professionals and managers when proposing future interventions.

Temporal trends in leptospirosis incidence and association with climatic and environmental factors in the state of Santa Catarina, Brazil. / Tendência temporal da leptospirose e sua associação com variáveis climáticas e ambientais em Santa Catarina, Brasil.

Leptospirosis is a zoonosis with epidemic potential, especially after heavy rainfall causing river, urban and flash floods. Certain features of Santa Catarina's coastal region influence these processes. Using negative binomial regression, we investigated trends in the incidence of leptospirosis in the six municipalities with the highest epidemic peaks between 2000 and 2015 and the climatic and environmental variables associated with the occurrence of the disease. Incidence was highest in 2008 and 2011, and peaks occurred in the same month or month after disasters. Incidence showed a strong seasonal trend, being higher in summer months. There was a decrease trend in incidence across the six municipalities (3.21% per year). The climatic and environmental factors that showed the strongest associations were number of rainy days, maximum temperature, presence of flash floods, and river flooding. The impact of these variables varied across the municipalities. Significant interactions were found, indicating that the effect of river flooding on incidence is not the same across all municipalities and differences in incidence between municipalities depend on the occurrence of river flooding.

A leptospirose é uma zoonose que apresenta potencial epidêmico, principalmente após fortes chuvas que acarretam inundações, alagamentos e enxurradas. Algumas características da região costeira de Santa Catarina, localizada no Sul do Brasil, influenciam nesses processos. Portanto, a partir do estudo da leptospirose nos seis municípios do estado com as maiores incidências e picos epidêmicos de 2000 a 2015, buscou-se conhecer a tendência dessa doença e as variáveis climáticas e ambientais associadas à sua ocorrência, ajustando dois modelos com resposta binomial negativa. As maiores incidências foram encontradas em 2008 e 2011, com picos no mesmo mês ou no posterior aos eventos de desastres. A incidência apresentou forte comportamento sazonal, sendo maior nos meses do verão. Observou-se tendência de queda na incidência dos municípios estudados, estimada em 3,21% ao ano. Os fatores climáticos e ambientais mais fortemente associados foram o número de dias de chuva, a temperatura máxima e a presença de enxurrada e de inundação, com diferentes impactos entre os municípios. Houve interações significativas, indicando que o efeito de inundações na incidência não é o mesmo em todos os municípios e que as diferenças nas incidências entre os municípios dependem da ocorrência ou não de inundações.

Working conditions are associated with the occurrence of sleepiness of nursing professionals: a case-control study.

Objectives: To identify the factors associated with the occurrence of sleepiness among nursing professionals. Material and Methods: A case-control study nested in a cross-sectional one, conducted with 364 controls and 121 cases. Data on demographic and occupational characteristics were collected, as well as about lifestyle, physical and psychosocial work environment and somnolence. A multiple logistic regression analysis was performed. Results: The independent factors associated with the presence of sleepiness were as follows: imbalance between efforts and rewards (ORa=3.81; p<0.001), high overcommitment (ORa=3.20; p<0.001), workload equal to or greater than 45 hours a week (ORa=2.30; p=0.001), situations that can generate pain/injury with moderate or high exposure (ORa=1.85; p=0.037), and night work (ORa=1.71; p=0.038). The model was adjusted by gender and age group. Conclusion: Individual and historical-occupational characteristics and, mainly, those related to the physical and psychosocial work environment, were associated with the occurrence of sleepiness. Public and institutional preventive policies must include improvements in the conditions of the physical and psychosocial work environment, as well as strengthening of the individual resources.

Effects of age, period, and birth cohort on homicide mortality in the city of São Paulo, Brazil, from 1996 to 2015.

Although São Paulo is the most populous city in Brazil - one of the world's most violent countries - a significant reduction in its homicide mortality rate (HMR) has been detected. This study aims to estimate the effects of age, period, and birth cohort on the trend of homicide mortality according to sex in the city of São Paulo, from 1996 to 2015. An ecological study was undertaken with data on deaths by homicide for both sexes, in all age brackets, in the city of São Paulo. Poisson models were adjusted for each sex to estimate the age-period-cohort effects. In total, 61,833 deaths by homicide were recorded among males and 5,109 among females. Regardless of the period, the highest HMR occurred in the 20-24 age bracket. Higher HMRs were found in those born in the 1970s and 1980s. The complete model, with age-period-cohort effects, were the best fit to the data. The risk of death by homicide declined over the periods, with lower intensity in the final five years (2011-2015), for both males (RR = 0.48; 95%CI: 0.46; 0.49) and females (RR = 0.52; 95%CI: 0.47; 0.57). A reduction was found in the risk of homicide, regardless of the sex or age bracket, and also in recent cohorts. However, the intensity of such reductions has been decreasing over time, which suggests that the public policies adopted have limited potential to maintain these achievements.

[Time trend in hospitalizations from motor vehicle accidents in the city of São Paulo, Brazil, 2000-2019]. / Tendência temporal das internações por acidentes de trânsito na cidade de São Paulo, Brasil, 2000-2019.

This study assessed the hospitalization rates from motor vehicle accidents in the Brazilian Unified National Health System (SUS) in residents of the city of São Paulo, Brazil, from 2000 to 2019, according to sex, age bracket, and means of transportation (pedestrians, cyclists, motorcyclists, and motor vehicle occupants). A segmented regression model with negative binomial response was adjusted with inflection points to accommodate possible changes in trends. 189,765 hospitalizations were recorded during the study period, mostly males (80.5%) and from 20 to 49 years of age (71.2%). The most frequent type of accident involved motorcyclists (42.8%), followed by run-over pedestrians (33.7%). In general, the period from 2000 to 2007 was marked by increasing hospitalization rates from motor vehicle accidents involving all means of transportation, in both sexes, and in most age brackets. The year when the rates stopped increasing (or in some cases began to drop) differed according to the means of transportation. For vehicle occupants and cyclists, the trend in most age brackets turned downward in 2008, but the same did not happen with pedestrians and motorcyclists until 2012. Starting in 2015, the decline stopped in pedestrians, and the rates in cyclists turned upward again in most age brackets. For motorcyclists, the rates turned upward again in men 20 to 59 years of age (7.2% per year, exceeding 140 per 100,000 inhabitants in 2019) and in women 15 to 39 years of age (4.9% per year). The benefits of traffic safety measures implemented thus far in Brazil may have reached their limit, so that the current control and prevention measures need to be revised.

Este estudo avaliou a tendência das taxas de internação por acidentes de trânsito no Sistema Único de Saúde (SUS), de residentes no Município de São Paulo, Brasil, entre 2000 e 2019, segundo sexo, faixa etária e meio de transporte (pedestres, ciclistas, motociclistas e ocupantes de veículo). Foi ajustado um modelo de regressão segmentada com resposta binomial negativa, com pontos de inflexão para acomodar possíveis mudanças de tendência. Foram registradas 189.765 internações durante o período de estudo, a maioria de homens (80,5%) com idade entre 20 e 49 anos (71,2%). O tipo de acidente mais frequente foi com motocicleta (42,8%), seguido dos atropelamentos de pedestres (33,7%). De um modo geral, o período de 2000 a 2007 foi marcado pelo crescimento das taxas de hospitalização por acidentes de trânsito para todos os meios de transporte, em ambos os sexos e na maioria das faixas etárias. O momento em que as taxas pararam de crescer ou que eventualmente passaram a cair foi diferente para os diferentes meios de transporte. Para ocupantes de veículos e ciclistas, a tendência na maioria das faixas etárias inverteu-se para uma de queda em 2008, mas para pedestres e motociclistas, isto só ocorreu em 2012. A partir de 2015, a queda cessou em pedestres e as taxas em ciclistas voltaram a subir, na maioria das faixas etárias. Para motociclistas, as taxas voltaram a crescer em homens de 20 a 59 anos (7,2% ao ano, atingindo valores superiores a 140 por 100 mil habitantes em 2019) e em mulheres, de 15 a 39 anos (4,9% ao ano). É possível que os benefícios das medidas de segurança implementadas até agora tenham atingido seu limite, de modo que as atuais medidas de controle e prevenção devem ser revistas.

Este estudio evaluó la tendencia de las tasas de internamiento por accidentes de tránsito en el Sistema Único de Salud, de residentes en el Municipio de São Paulo, Brasil, entre 2000 y 2019, según sexo, franja de edad y medio de transporte (peatones, ciclistas, motociclistas y ocupantes de vehículo). Fue ajustado a un modelo de regresión segmentada con respuesta binomial negativa, con puntos de inflexión para acomodar posibles cambios de tendencia. Se registraron 189.765 internamientos durante el período de estudio, la mayoría de hombres (80,5%) con edad entre 20 y 49 años (71,2%). El tipo de accidente más frecuente fue con motocicleta (42,8%), seguido de atropellamientos de peatones (33,7%). De modo general, el período de 2000 a 2007 estuvo marcado por el crecimiento de las tasas de hospitalización por accidentes de tránsito para todos los medios de transporte, en ambos sexos, y en la mayoría de las franjas de edad. El momento en el que las tasas pararon de crecer, o que eventualmente pasaron a caer, fue diferente para los diferentes medios de transporte. En el caso de ocupantes de vehículos y ciclistas, la tendencia en la mayoría de las franjas de edad se invirtió hacia una caída en 2008, pero en peatones y motociclistas, esto solo ocurrió en 2012. A partir de 2015, la caída cesó en peatones y las tasas en ciclistas volvieron a subir, en la mayoría de las franjas de edad. Para los motociclistas, las tasas volvieron a crecer en hombres de 20 a 59 años (7,2% al año, alcanzando valores superiores a 140 por 100 mil habitantes en 2019) y en mujeres, de 15 a 39 años (4,9% al año). Es posible que los beneficios de las medidas de seguridad implementadas hasta ahora hayan alcanzado su límite, de modo que las actuales medidas de control y prevención deben ser revisadas.

Residential traffic exposure and lymphohematopoietic malignancies among children in the city of São Paulo, Brazil: An ecological study.

BACKGROUND: Despite widespread evidence that air pollution is carcinogenic, there is little evidence from low-middle income countries, especially related to childhood malignancies. We examined the role of traffic related pollution on lymphohematopoietic malignancies among under-14 s in Sao Paulo. METHODS: All incident cases between 2002 and 2011 were collected from a population-based registry. Exposures were assigned on residential address at diagnosis via traffic density database (for the year 2008) and a satellite derived NO2 land use regression model (averaged between 1997 and 2011). Incidence rate ratios (IRRs) were calculated via Poisson Regression adjusted by age, gender and socioeconomic status (SES), with additional stratification by SES. RESULTS: A positive association between traffic and NO2 with some lymphohematopoietic malignancies was observed with the degree of effect differing by SES. For example, lymphoid leukemia IRRs in the lower SES group were 1.21 (95 % CI: 1.06, 1.39) for traffic density and 1.38 (95 % CI: 1.13, 1.68) for NO2. In the higher group they were 1.06 (95 % CI: 1.00, 1.14) and 1.37 (95 % CI: 1.16, 1.62). CONCLUSION: NO2 and traffic density were associated with Hodgkin lymphoma and lymphoid leukemia among children in São Paulo. Differing IRRs by gender and SES group indicate differences in underlying risk and/or exposure profiles.

A palliative prognostic score for terminally ill children and adolescents with cancer.

BACKGROUND: The loss of a child is considered the hardest moment in a parent's life. Studies addressing length of survival under pediatric palliative care are rare. The aim of this study was to improve a survival prediction model for children in palliative care, as accurate information positively impacts parent and child preparation for palliative care. PROCEDURE: Sixty-five children referred to a pediatric palliative care team were followed from August 2003 until December 2006. Variables investigated (also included in previous studies) were: diagnosis, home care provider, presence of anemia, and performance status score given by the home care provider. Clinical variables such as symptom number were also used to test the score's ability to predict survival. RESULTS: The length of survival prognostic score was validated using the above variables. The number of symptoms at transition to palliative care does not improve the score's predictive ability. The sum of the single scores gives an overall score for each patient, dividing the population into three groups by probability of 60-day survival: Group A 80.0%, Group B 38.0%, and Group C 28.5% (P < 0.001). CONCLUSION: A pediatric palliative care score based on easily accessible variables is statistically significant in multivariate analysis. Factors that increase accuracy of life expectancy prediction enable adequate information to be given to patients and families, contributing to therapeutic decision-making issues.
