Apparent prevalence and risk factors for bovine tuberculosis in the state of Paraná, Brazil: an assessment after 18 years since the beginning of the Brazilian program.

Bovine tuberculosis (bTB) impacts considerably animal production and one health worldwide. To describe the prevalence, risk factors, and spatial pattern of the disease in the state of Paraná, Brazil, a cross-sectional study was conducted from September 2018 to February 2019. The area was divided into seven regions. Within each region, farms were randomly selected, and a predetermined number of cows was selected and tested by a comparative cervical tuberculin test. 17,210 animals were tested across 1757 farms. Herd prevalence of bTB-infected herds in Paraná was 2.5% [1.87-3.00%]. It has varied from 0.8 to 3.98% among seven regions, with clustering being detected in the west, central, and northeast areas. Animal prevalence was 0.35% [0.21-0.59%] and has varied from 0.08 to 0.6% among the pre-set regions. No major shifts in the prevalence of bTB were detected since 2007. Large-sized herds, dairy production, and feeding with whey were detected to be correlated with the presence of bTB. Exclusively among dairy herds, veterinary assistance from cooperatives, possession of self-owned equipment to cool milk, and feeding with whey were correlated with the disease. Considering these results, it is recommended that the state of Paraná seek to implement a surveillance system for the detection of bTB-infected herds transforming them into free ones, if possible, incorporating elements of risk-based surveillance. Health education is also recommended to inform farmers about the risks of introducing animals without testing and of feeding raw whey to calves.

Seroprevalence and risk factors for bovine brucellosis in the state of Paraná, Brazil: an analysis after 18 years of ongoing control measures.

Seroprevalence and risk factors of bovine brucellosis (Brucella abortus) in herds and cattle were estimated by a cross-sectional study in the state of Paraná, Brazil. The state was divided into seven regions and a random, two-stage sampling was performed on properties and cattle from each region between 2018 and 2019. Serum samples were collected from 11,592 cows over 24 months from 1,757 properties and a questionnaire was applied to identify potential risk factors. As recommended by the National Program for the Control and Eradication of Animal Brucellosis and Tuberculosis (PNCEBT), serological testing for the detection of anti-Brucella antibodies included the buffered plate agglutination test (screening test) and the fluorescence polarization assay (confirmatory test). The seroprevalence of bovine brucellosis on properties and in cattle was 4.87% (95% confidence interval [CI]: 3.98-5.93%) and 2.24% (95% CI: 1.47-3.41%), respectively. Multiple logistic regression analysis identified larger herd size and failure to test for brucellosis as risk factors for the presence of anti-B. abortus antibodies. These results demonstrate no change in the prevalence when comparing initial studies conducted in 2002. Given our findings, it is recommended that policies for brucellosis control include a widespread vaccination program for higher prevalence areas and eradication approach to lower prevalence areas. All steps related to correct immunization of the herds should be verified and improved by training and education. Health education action must be carried out informing farmers about the risks of introducing animals not tested for brucellosis into their herds and the benefits of testing their herds regularly.

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.

Intra-urban spatial variability of breast and cervical cancer mortality in the city of São Paulo: analysis of associated factors. / Variabilidade espacial intraurbana da mortalidade por câncer de mama e do colo do útero no município de São Paulo: análise dos fatores associados.

OBJECTIVE: To identify spatial variability of mortality from breast and cervical cancer and to assess factors associated in the city of São Paulo. METHODS: Between 2009 and 2016, 10,124 deaths from breast cancer and 2,116 deaths from cervical cancer were recorded in the Mortality Information System among women aged 20 years and over. The records were geocoded by address of residence and grouped according to Primary Health Care coverage areas. A spatial regression modeling was put together using the Bayesian approach with a Besag-York-Mollié structure to verify the association of deaths with selected indicators. RESULTS: Mortality rates from these types of cancer showed inverse spatial patterns. These variables were associated with breast cancer mortality: travel time between one and two hours to work (RR - relative risk: 0.97; 95%CI - credible interval: 0.93-1.00); women being the head of the household (RR 0.97; 95%CI 0.94-0.99) and deaths from breast cancer in private health institutions (RR 1.04; 95%CI 1.00-1.07). The following variables were associated with mortality from cervical cancer: travel time to work between half an hour and one hour (RR 0.92; 95%CI 0.87-0.98); per capita household income of up to 3 minimum wages (RR 1.27; 95%CI 1.18-1.37) and ratio of children under one year of age related to the female population aged 15 to 49 years (RR 1.09; 95%CI 1.01-1.18). CONCLUSION: The predicted RR for mortality from these cancers were calculated and associated with the socioeconomic conditions of the areas covered.

OBJETIVO: Identificar a variabilidade espacial da mortalidade por câncer de mama e colo do útero e avaliar fatores associados à mortalidade por esses cânceres no município de São Paulo. MÉTODOS: Entre 2009 e 2016 foram registrados, no Sistema de Informações sobre Mortalidade, 10.124 óbitos por câncer de mama e 2.116 óbitos por câncer do colo do útero em mulheres com 20 anos e mais. Os registros foram geocodificados por endereço de residência e agregados segundo território adstrito. Foram realizadas modelagens de regressão espacial utilizando-se a abordagem bayesiana com estrutura de Besag-York-Mollié para verificar a associação dos óbitos com indicadores selecionados. RESULTADOS: As taxas de mortalidade por esses cânceres apresentaram padrões espaciais inversos. As variáveis associadas à mortalidade por câncer de mama foram: tempo de deslocamento para o trabalho entre uma e duas horas (risco relativo ­ RR 0,97; intervalo de credibilidade ­ IC95% 0,93­1,00); mulheres responsáveis pelo domicílio (RR 0,97; IC95% 0,94­0,99) e óbitos por câncer de mama ocorridos em estabelecimentos privados (RR 1,04; IC95% 1,00­1,07). À mortalidade por câncer do colo do útero, estiveram associados: tempo de deslocamento para o trabalho entre meia e uma hora (RR 0,92; IC95% 0,87­0,98); rendimento domiciliar até três salários-mínimos (RR 1,27; IC95% 1,18­1,37); e razão de menores de um ano em relação à população feminina de 15 a 49 anos (RR 1,09; IC95% 1,01­1,18). CONCLUSÃO: Foram calculados os RR preditos para a mortalidade por esses cânceres, que estiveram associados às condições socioeconômicas das áreas de abrangência.

Adverse event classification and signal detection of data from the customer service and pharmacovigilance of a multinational veterinary pharmaceutical company.

The pharmacovigilance of a veterinary company may include the analysis of spontaneous reports of adverse events (AE) related to its products. The present study developed an AE classification flowchart to analyze AE notified to the customer service and pharmacovigilance department of a multinational veterinary pharmaceutical company in Brazil. The product-AE binomials using the flowchart were characterized in terms of their frequencies and subsequently, three signal detection models were used: Reporting Odds Ratio, Bayesian confidence propagation neural network, and Gamma Poisson Shrinker. The signals detected with the three methods were classified according to their intensity, always with the most intense signal in the first position. Among the signals detected by the three methods, the positions of each signal were summed to obtain an aggregated classification that considered the results of the three methods and allowed a serial interpretation. Among the 531 reports, 20 types of AE; 88 product-AE binomials were identified. From the total of reports, seven were signs identified by the three methods. The classification of AE following explicit criteria and the combined use of more than one signal detection method enhances spontaneous-reports-based pharmacovigilance.

Spatio-temporal dynamics of dengue-related deaths and associated factors.

Since the reintroduction of dengue viruses in 1987, Sao Paulo State (SP), Brazil, has experienced recurrent epidemics in a growing number of municipalities, each time with more cases and deaths. In the present study, we investigated the spatio-temporal dynamics of dengue-related deaths and associated factors in SP. This was an ecological study with spatial and temporal components, based on notified dengue-related deaths in the municipalities of SP between 2007 and 2017. A latent Gaussian Bayesian model with Poisson probability distribution was used to estimate the standardized mortality ratios (SMR) for dengue and relative risks (RR) for the socioeconomic, demographic, healthcare-related, and epidemiological factors considered. Epidemiological factors included the annual information on the number of circulating serotypes. A total of 1,019 dengue-related deaths (0.22 per 100,000 inhabitant-years) between 2007 and 2017 were confirmed in SP by laboratory testing. Mortality increased with age, peaking at 70 years or older (1.41 deaths per 100,000 inhabitant-years). Mortality was highest in 2015, and the highest SMR values were found in the North, Northwest, West, and coastal regions of SP. An increase of one circulating serotype, one standard deviation in the number of years with cases, and one standard deviation in the degree of urbanization were associated with increases of 75, 35, and 45% in the risk of death from dengue, respectively. The risk of death from dengue increased with age, and the distribution of deaths was heterogeneous in space and time. The positive relationship found between the number of dengue serotypes circulating and years with cases at the municipality/micro-region level indicates that this information can be used to identify risk areas, intensify surveillance and control measures, and organize healthcare to better respond to this disease.

One Health of Peripheries: Biopolitics, Social Determination, and Field of Praxis.

Amid the urgency to solve countless and severe health problems, asking what is health or who can and must have it may seem like a waste of time. However, some responses can reveal prevailing practices that divert attention from fundamental problems, thus maintaining privileges and deepening health inequities. One Health of Peripheries arises from these questions and takes three interdependent senses. The first refers to attributes determining the well-being and suffering of peripheral multispecies collectives: a state, a process, the realization of capacities. The second problematizes marginalizing apparatuses that define health and who can and should have it. The third encompasses practices in more-than-human social spaces in which, and through which, One Health is experienced, understood, and transformed. The qualification of health as "one" does not refer to the lack of plurality, nor to the simple aggregation of health fragments (human + animal + environmental), but to the complexity of health in a field with peripheral places, ensuing from margins to privilege those who are inside and legitimize the exploitation of those who are outside. The interaction among margins creates degrees and kinds of privilege and vulnerability that materialize epidemiologic profiles while articulating different peripheral strengths and needs supports a collective resistance to break margins. Social determination, a key concept in the (Latin American) collective health movement, underlies such profiles. However, this movement overlooks the more-than-human dimension of social determination; that is to say, One Health of Peripheries is a blind spot of collective health. The cartography of One Health of Peripheries has unique needs regarding participation, research, and inclusive policies for the decolonial promotion of healthy lifestyles.

From Modern Planetary Health to Decolonial Promotion of One Health of Peripheries.

The concept of Planetary Health has recently emerged in the global North as a concern with the global effects of degraded natural systems on human health. It calls for urgent and transformative actions. However, the problem and the call to solve it are far from new. Planetary health is a colonial approach that disregards alternative knowledge that over millennia have accumulated experiences of sustainable and holistic lifestyles. It reinforces the monolog of modernity without realizing that threats to "planetary health" reside precisely in its very approach. It insists on imposing its recipes on political, epistemological, and ontological peripheries created and maintained through coloniality. The Latin American decolonial turn has a long tradition in what could be called a "transformative action," going beyond political and economic crises to face a more fundamental crisis of civilization. It deconstructs, with other decolonial movements, the fallacy of a dual world in which the global North produces epistemologies, while the rest only benefit from and apply those epistemologies. One Health of Peripheries is a field of praxis in which the health of multispecies collectives and the environment they comprise is experienced, understood, and transformed within symbolic and geographic peripheries, ensuing from marginalizing apparatuses. In the present article, we show how the decolonial promotion of One Health of Peripheries contributes to think and advance decentralized and plural practices to attend to glocal realities. We propose seven actions for such promotion.

Pink October and mammograms: when health communication misses the target. / Outubro Rosa e mamografias: quando a comunicação em saúde erra o alvo.

Breast cancer is the most frequently diagnosed type of cancer and is the leading cause of death from cancer in the female population. Screening mammograms and early treatment are the most frequently used means to attempt to reduce this mortality and are promoted during Pink October, an annual awareness-raising campaign. However, recent studies have correlated the increase in screening with higher morbidity and mortality, due to overdiagnosis and overtreatment. The current study assessed searches related to breast cancer and mammogram in Google Trends from 2004 to 2019 in terms of trend, seasonality, and distribution in Brazilian states. The study also evaluatedH the correlation between the number of searches in Google Trends and the number of screening mammograms. The two series showed a seasonal pattern with peaks in October, and there was an excess in tests performed outside the recommended age bracket. Pink October transmitted and popularized health information and induced behaviors related to this information, which are three desirable aspects in health communication and education. However, the campaign also generated an excess in screening mammograms and did not encourage autonomy and free and informed consent. Pink October revealed both the potential of mass communication in health and the need for messages to be aligned with the best available scientific evidence.

O câncer de mama é o tipo de câncer mais diagnosticado e a principal causa de morte por câncer na população feminina. As mamografias de rastreamento e o tratamento precoce são geralmente os meios mais utilizados na tentativa de reduzir essa mortalidade e são incentivados no Outubro Rosa, uma campanha de divulgação anual. Contudo, estudos recentes têm relacionado o aumento do rastreamento com uma maior morbimortalidade em razão do sobrediagnóstico e do sobretratamento. No presente estudo, avaliaram-se as buscas relativas ao câncer de mama e à mamografia no Google Trends, entre 2004 e 2019, em termos da tendência, da sazonalidade e da distribuição nas Unidades Federativas brasileiras. Avaliou-se também a correlação entre a quantidade de buscas no Google Trends e a quantidade de exames de rastreamento mamográfico. As duas séries tiveram um padrão sazonal com picos em outubro, e houve excesso de exames realizados fora da faixa etária recomendada. O Outubro Rosa transmitiu informações de saúde, as popularizou e induziu comportamentos relativos a informações transmitidas; três aspectos desejáveis na comunicação e na educação em saúde. Porém, gerou um excesso de mamografias de rastreamento e não incentivou a autonomia e o consentimento livre e esclarecido. O Outubro Rosa mostrou o potencial da comunicação em saúde para massas e a necessidade de que as mensagens sejam alinhadas com as melhores evidências científicas.

Total antibiotic use in a state-wide area and resistance patterns in Brazilian hospitals: an ecologic study.

INTRODUCTION: Use of antibiotic and bacterial resistance is the result of a complex interaction not completely understood. OBJECTIVES: To evaluate the impact of entire antimicrobial use (community plus hospitals) on the incidence of bloodstream infections in intensive care units adjusted by socioeconomic factors, quality of healthcare, and access to the healthcare system. DESIGN: Ecologic study using a hierarchical spatial model. SETTING: Data obtained from 309 hospitals located in the state of São Paulo, Brazil from 2008 to 2011. PARTICIPANTS: Intensive care units located at participant hospitals. OUTCOME: Hospital acquired bloodstream infection caused by MDRO in ICU patients was our primary outcome and data were retrieved from São Paulo Health State Department. Socioeconomic and healthcare indexes data were obtained from IBGE (Brazilian Foundation in charge of national decennial census) and SEADE (São Paulo Planning and Development Department). Information on antimicrobial sales were obtained from IMS Brazil. We divided antibiotics into four different groups (1-4). RESULTS: We observed a direct association between the use of group 1 of antibiotics and the incidences of bloodstream infections caused by MRSA (1.12; 1.04-1.20), and CR-Acinetobacter sp. (1.19; 1.10-1.29). Groups 2 and 4 were directly associated to VRE (1.72; 1.13-2.39 and 2.22; 1.62-2.98, respectively). Group 2 was inversely associated to MRSA (0.87; 0.78-0.96) and CR-Acinetobacter sp. (0.79; 0.62-0.97). Group 3 was inversely associated to Pseudomonas aeruginosa (0.69; 0.45-0.98), MRSA (0.85; 0.72-0.97) and VRE (0.48; 0.21-0.84). No association was observed for third generation cephalosporin-resistant Klebsiella pneumoniae and Escherichia coli. CONCLUSIONS: The association between entire antibiotic use and resistance in ICU was poor and not consistent for all combinations of antimicrobial groups and pathogens even after adjusted by socioeconomic indexes. Selective pressure exerted at the community level seemed not to affect the incidences of MDRO infection observed in intensive care setting.

Can sterilization help to prevent roaming in owned dogs and cats?

In many locations, the highest proportion of roaming dogs and cats, might have owners. The prevention of roaming in owned dogs and cats is a key intervention to reduce the number of unsupervised animals in public spaces. Sterilization is an important population management intervention but it is unclear if, apart from its effects on birth rates and animal behavior, it also affects the roaming status of owned dogs and cats. We formulated a directed acyclic graph to represent a causal hypothesis regarding the effect of sex, age and sterilization on roaming behavior in owned dogs and cats. The causal hypothesis was tested using survey data and Bayesian multilevel logistic regressions. The odds of roaming were lower in sterilized dogs and cats but the credible interval (CI) supported the effect of sterilization only for dogs. The odds of roaming were higher in both male dogs and cats and the CI supported the effect of sex. The CI did not support the effect of age on roaming, irrespective of species. If the observed association between sterilization and roaming was causal, then sterilization may contribute to a reduction in roaming. Studies on other populations and the exploration of other potential determinants of roaming are required to better understand the causal relationship between sterilization and roaming.

Spatial pattern of mortality from breast and cervical cancer in the city of São Paulo.

OBJECTIVE: To verify the spatial pattern of mortality from breast and cervical cancer in areas of primary health care, considering socioeconomic conditions. METHODS: This is an ecological study, from January 2000 to December 2016. The study area is the municipality of São Paulo, Brazil, and its 456 coverage areas of primary health units. Information on deaths of women aged 20 years or over were geocoded according to residence address. We calculated mortality rates, standardized by age, and smoothed by the local empirical Bayesian method, and grouped into three or two years to reduce the random fluctuation of the data. In addition, bivariate global and local Moran indexes were calculated to verify the existence of spatial agglomeration of standardized mortality rates with a domain of socioeconomic condition, elaborated based on the Índice Paulista de Vulnerabilidade Social (IPVS - São Paulo Index of Social Vulnerability). RESULTS: The success rate of geocoding was 98.9%. Mortality from breast cancer, without stratification by time, showed a pattern with higher rates located in central regions with better socioeconomic conditions. It showed a decrease at the end of the period and a change in spatial pattern, with increased mortality in peripheral regions. On the other hand, mortality from cervical cancer remained with the highest rates in peripheral regions with worse socioeconomic conditions, despite being reduced over time. CONCLUSION: The spatial pattern of mortality from the studied cancers, over time, suggests association with the best socioeconomic conditions of the municipality, either as protection (cervical) or risk (breast). This knowledge may direct resources to prevent and promote health in the territories.

Size, spatial and household distribution, and rabies vaccination coverage of the Brazilian owned-dog population.

Dog rabies and human rabies transmitted by dogs can be prevented through adequate dog vaccination coverage. For surveillance purposes, this coverage must be calculated using accurate population size estimates to avoid misleading conclusions. We used data from a Brazilian national survey comprising 64,348 households, to calculate point estimates and confidence intervals of the size, household density, and rabies vaccination coverage of the owned-dog population in Brazilian federative units. We also evaluated the precision of owned-dog population size estimates, based on the extrapolation among different areas, of the mean number of dogs per household and the human/dog ratio. The estimated owned-dog population size in Brazil was 52,198,324 (95% CI = 51,028,583-53,368,066) and the dog vaccination coverage was 80.09% (95% CI = 79.09%-81.09%). Both estimates had marked variation across Brazilian federative units and urban/rural strata. Only two of the 27 federative units had a confidence interval in rural vaccination coverage above 70% and six did not pass this threshold in their urban stratum. For the first time, we reported probabilistic estimates for an entire country and its main administrative areas. The estimated coverage for the country was high because the most populated federative unit also had high coverage. The mean number of dogs per household and the human/dog ratio were useful as survey estimates to characterize owned-dog density. However, the simple extrapolation of these parameters resulted in estimates of owned-dog population sizes with large errors (up to 254%) that must be interpreted with caution to avoid misleading conclusions. To evaluate the dog population size, we recommend the use of probabilistic sampling designs instead of simple human/dog ratio extrapolations, and the inclusion of animal-related questions in censuses and national surveys to obtain reliable estimates to support improvements in animal and human health.

Environmental and socioeconomic analysis of malaria transmission in the Brazilian Amazon, 2010-2015.

OBJECTIVE: To analyze the environmental and socioeconomic risk factors of malaria transmission at municipality level, from 2010 to 2015, in the Brazilian Amazon. METHODS: The municipalities were stratified into high, moderate, and low transmission based on the annual parasite incidence. A multinomial logistic regression that compared low with medium transmission and low with high transmission was performed. For each category, three models were analyzed: one only with socioeconomic risk factors (Gini index, illiteracy, number of mines and indigenous areas); a second with the environmental factors (forest coverage and length of the wet season); and a third with all covariates (full model). RESULTS: The full model showed the best performance. The most important risks factors for high transmission were Gini index, length of the wet season and illiteracy, OR 2.06 (95%CI 1.19-3.56), 1.73 (95%CI 1.19-2.51) and 1.10 (95%CI 1.03-1.17), respectively. The medium transmission showed a weaker influence of the risk factors, being illiteracy, forest coverage and indigenous areas statistically significant but with marginal influence. CONCLUSIONS: As a disease of poverty, the reduction in wealth inequalities and, therefore, health inequalities, could reduce the transmission considerably. Besides, environmental risk factors as length of the wet season should be considered in the planning, prevention and control. Municipality-level and fine-scale analysis should be done together to improve the knowledge of the local dynamics of transmission.

Field-testing a single-dose immunocontraceptive in free-ranging male capybara (Hydrochoerus hydrochaeris): Evaluation of effects on reproductive physiology, secondary sexual characteristics, and agonistic behavior.

Controlling wildlife populations to mitigate human-wildlife conflicts and the spread of zoonotic diseases is an ever-growing necessity. The objective of this study was to evaluate a single-dose anti-gonadotropin-releasing hormone vaccine (GonaCon, USDA/NWRC, Fort Collins, CO, USA) as a non-lethal alternative for population control in free-ranging, synanthropic male capybara. In addition to infertility efficacy of this treatment, potential effects on the alpha male's secondary sexual characteristics and agonist behavior need to be assessed because any alterations in these factors could lead to population management failure. The treatment group (n = 3) received 1 mL of the anti-GnRH vaccine, intramuscularly, and the control group (n = 2) a 1 mL sham vaccine. Reproductive behavior and social group dynamics were monitored for 30 days prior to inoculation (June 2017) with continuous observations occurring during the study period. Antifertility effects were assessed by conducting exams of testicular morphology, semen characteristics, and histological analysis (after 270 days via hemi-gonadectomy). Compared to the control group, the testicles of the treated males had severe atrophy (P <  0.05), oligozoospermia and greater numbers of sperm cells in a static developmental phase. Courtship and agonistic alpha male behavior were not altered, and the group's social integrity was maintained. Results indicate there was 100% infertility in capybara males, observed throughout the study period of 18 months, and equally important, the male's alpha characteristics were not affected by the treatment, which is imperative for successful capybara population control efforts.

[Influence of vehicular traffic density on hospital admissions due to respiratory tract cancer in the city of São Paulo, Brazil]. / Influência da densidade de tráfego veicular na internação por câncer do aparelho respiratório no Município de São Paulo, Brasil.

Pollution related to traffic is a major problem in urban centers and a large portion of the population is vulnerable to its health effects. This study sought to identify a potential association between hospital admissions due to respiratory tract cancer and vehicular traffic density in the city of São Paulo, Brazil. It is an ecological study of the public (Hospital Inpatient Authorization - AIH, in Portuguese) and private (Hospital Inpatient Communication - CIH, in Portuguese) health care systems, from 2004 to 2006, geocoded by individuals' residential addresses. Using a Besag-York-Mollié ecological model, we initially evaluated the relationship between number of cases of hospital admission due to respiratory tract cancer in each weighting area and the standardized co-variables: traffic density and Municipal Human Development Index (MHDI) as indicator of socioeconomic status. Using a classic Poisson model, we then evaluated the risk associated with growing traffic density categories. The Besag-York-Mollié model estimated a RR = 1.09 (95%CI: 1.02-1.15) and RR = 1.19 (95%CI: 1.10-1.29) of admission due to respiratory tract cancer for each increase of one standard deviation of traffic and MHDI, respectively. The Poisson model also showed a clear exposure-response gradient for admission due to respiratory tract cancer (IRR = 1.11; 95%CI: 1.07-1.15, for each 10 units of added traffic density). This study suggests that there is an association between residing in areas with high traffic density and hospital admissions due to respiratory tract cancer in the city of São Paulo.

A poluição relacionada ao tráfego é um grande problema nos centros urbanos, e uma grande parcela da população fica vulnerável aos seus efeitos à saúde. Este trabalho teve como objetivo identificar potencial associação entre as internações hospitalares por câncer do aparelho respiratório com a densidade de tráfego veicular no Município de São Paulo, Brasil. É um estudo ecológico com dados de internações hospitalares por câncer dos sistemas público (Autorização de Internação Hospitalar - AIH) e particular (Comunicação de Internação Hospitalar - CIH), de 2004 a 2006, geocodificados por endereço de residência do indivíduo. Mediante um modelo ecológico de Besag-York-Mollié foi avaliada inicialmente a relação entre o número de casos de internação por câncer do aparelho respiratório em cada área de ponderação e as covariáveis padronizadas: densidade de tráfego e Índice de Desenvolvimento Humano Municipal (IDHM) como indicador de status socioeconômico. Sequencialmente, com um modelo clássico de Poisson, procedeu-se uma avaliação do risco associado às categorias crescentes de densidade de tráfego. O modelo de Besag-York-Mollié estimou um RR = 1,09 (IC95%: 1,02-1,15) e RR = 1,19 (IC95%: 1,10-1,29) de internação por câncer do aparelho respiratório, para cada aumento de um desvio padrão da densidade de tráfego e IDHM, respectivamente. Foi também evidenciado pelo modelo de Poisson um claro gradiente de exposição-resposta para internação por câncer respiratório (IRR = 1,11; IC95%: 1,07-1,15, para cada dez unidades de acréscimo da densidade de tráfego). Este trabalho sugere que há associação entre residir em áreas com alta densidade de tráfego e internação por câncer do aparelho respiratório no Município de São Paulo.

La contaminación relacionada con el tráfico es un gran problema en los centros urbanos, y una gran parte de la población es vulnerable a sus efectos para la salud. El objetivo de este trabajo fue identificar la potencial asociación entre los internamientos hospitalarios por cáncer del aparato respiratorio con la densidad del tráfico vehicular en el Municipio de São Paulo, Brasil. Es un estudio ecológico con datos de internamientos hospitalarios por cáncer de los sistemas público (Autorización de Internación Hospitalaria - AIH) y particular (Comunicación de Internación Hospitalaria - CIH), de 2004 a 2006, geocodificados por dirección de residencia del individuo. Mediante el modelo ecológico de Besag-York-Mollié se evaluó inicialmente la relación entre el número de casos de internamiento por cáncer del aparato respiratorio en cada área de ponderación y covariables estandarizadas: densidad de tráfico e Índice de Desarrollo Humano Municipal (IDHM), como indicador de estatus socioeconómico. Secuencialmente, con un modelo clásico de Poisson, se procedió a una evaluación del riesgo asociado a las categorías crecientes de densidad de tráfico. El modelo de Besag-York-Mollié estimó un RR = 1,09 (IC95%: 1,02-1,15) y RR = 1,19 (IC95%: 1,10-1,29) de internamiento por cáncer del aparato respiratorio, para cada aumento de un desvío estándar de la densidad de tráfico e IDHM, respectivamente. Se evidenció también, a través del modelo de Poisson, un claro gradiente de exposición-respuesta para el internamiento por cáncer respiratorio (IRR = 1,11; IC95%: 1,07-1,15, para cada 10 unidades de incremento de la densidad de tráfico). Este trabajo sugiere que existe una asociación entre residir en áreas con alta densidad de tráfico y el internamiento por cáncer del aparato respiratorio en el Municipio de São Paulo.

Spatiotemporal dynamics and risk factors for human Leptospirosis in Brazil.

Leptospirosis is an emerging neglected tropical disease with a worldwide significant global health burden. Between 2000 and 2016, there were 63,302 cases of human leptospirosis and 6,064 deaths reported in Brazil. We modeled the spatiotemporal risk dynamics of human leptospirosis morbidity and lethality, and attributed an easily interpretable risk-based priority index (PI) for all Brazilian federative units to suggest improvements to the national surveillance system. We also developed a conceptual framework of causality and estimated the effects of environmental and socioeconomic determinants of morbidity and lethality. Spatiotemporal risk patterns of morbidity and lethality differed. For morbidity, the pattern was mainly spatial, whereas lethality was mainly explained by the spatiotemporal interaction. The hypothesized causal model explained a relevant fraction of the heterogeneity in the spatial and spatiotemporal interaction patterns. The increase in soil moisture, precipitation, poverty, and the decrease in the proportion of urban households, acted as risk factors. The increase in the proportion of households in which waste is directly collected and in temperature were preventive factors. The structured temporal trend was increasing for morbidity and decreasing for lethality. In terms of morbidity, it was clear that the prioritization should be focused in a couple of states, mainly Acre. In terms of lethality, the allocation of resources need not be as asymmetric, but there was nonetheless a prioritization order. The proposed approach can be used to characterize spatiotemporal dynamics of other diseases and to inform decision makers.

Problematizando as alteridades para uma compreensão feminista e decolonial da Saúde Única em Periferias / Problematizing alterities for a feminist and decolonial understanding of One Health of Peripheries

Resumo Neste trabalho, refletimos sobre o modo como diversas figuras de alteridade são alvo de marginalização e o que isso implica em termos de reconhecimento nas gramáticas políticas que estabelecem quem pode se tornar um sujeito da saúde. A partir de contribuições feministas e decoloniais, discutimos algumas premissas ontológicas acerca da relação entre humanos, não humanos e a natureza, para alargar o entendimento da Saúde Única em Periferias. Também incorporamos narrativas de adolescentes que moram na favela Jardim São Remo (São Paulo, SP) e atuam como Agentes Mirins da Saúde Única em Periferias. Em diálogo com eles, exploramos o processo de exclusão constitutiva das favelas, apoiado em retóricas que não reconhecem a pluralidade das configurações coletivas e reforçam a figura das favelas como ameaça à segurança pública. Em contraposição a esse projeto, trazemos os princípios de reflorestamento e da confluência de alteridades significativas para reforçar a justiça multiespécie promovida pela práxis da Saúde Única em Periferias.

Abstract In this work, we reflect on how different figures of alterity are targets of marginalization and what this implies in terms of recognition in political grammars that establish who can become a subject of health. Based on feminist and decolonial contributions, we discuss some ontological assumptions about the relationship between humans, non-humans, and nature to broaden the understanding of the One Health of Peripheries. We also incorporate some narratives of adolescents who live in the Jardim São Remo favela (São Paulo, SP) and act as One Health of Peripheries Young Agents. In dialogue with them, we explore the process of constitutive exclusion of favelas, based on rhetorics that do not recognize the plurality of collective configurations and reinforce the figure of favelas as a threat to public security. In contrast to this project, we bring the principles of reforestation and confluence of significant alterities to reinforce the multispecies justice promoted by the praxis of One Health of Peripheries.

Companion animal demography and population management in Pinhais, Brazil.

We used a two-stage cluster sampling design to estimate the population sizes of owned dogs and cats in Pinhais, Brazil. For dogs, we simulated the population dynamics using a compartmental model of coupled differential equations, incorporating uncertainties in a global sensitivity analysis and identifying the most influential parameters through local sensitivity analysis. The calibration with the known human population improved precision in population size for dogs but not for cats. Population pyramids had a wide base, and the apparent population turnover was lower than the net population gain. Most immigrants came from the state capital. Projected dog and human growth rates between 2017 and 2027 were positive and similar, while the projected proportion of sterilized dogs decreased over the same period. The main reason provided for not sterilizing animals was the cost of the procedure, even though there were free alternatives. The demographic characterization made in the present study will serve for future comparisons and as a reference in epidemiological contexts. The simulations indicated what to expect in specific scenarios and stressed the need to increase current sterilization rates.
