Spatio-temporal dynamics of visceral leishmaniasis in Brazil: A nonlinear regression analysis.

AIMS: This study describes the spatio-temporal dynamics of new visceral leishmaniasis (VL) cases notified in Brazil between 2001 and 2020. METHODS AND RESULTS: Data on the occurrence of the disease were obtained by means of the Notifiable Diseases Information System of the Brazilian Ministry of Health. Joinpoint, temporal generalized additive models and conditional autoregressive (CAR) models were used to analyse the temporal evolution of the rates in Brazil, states and regions. Spatio-temporal generalized additive and CAR models were used to identify the distribution of annual risks of VL occurrence in the Brazilian territory in relation to variation in the spatial average. There were 63,966 VL cases in the target period (3.198 cases/year), corresponding to a mean incidence rate of 1.68 cases/100,000 inhabitants. Of these, 4451 resulted in deaths, which gives a mean mortality rate of 0.12 deaths/100,000 inhabitants and a case fatality of 6.96%. The highest incidence rate was found in the North region, followed closely by the Northeast region, which presented the second and first highest mortality rates, respectively. For all of Brazil, and in the Northeast region, there were stability in the incidence rates, while the other regions showed an increasing trend in different time segments in the period: Central-West up to 2011, North up to 2008, Southeast up to 2004, and South up to 2010. On the other hand, all regions experienced a reduction in incidence rate during the last years of the series. The Northeast region had the highest number of municipalities with statistically significant elevated relative risks. The spatio-temporal analysis showed the highest risk area predominantly in the Northeast region in the beginning of the time series. From 2002 to 2018, this area expanded to the interior of the country. CONCLUSIONS: The present study has shown that VL has expanded in Brazil. However, the North and Northeast regions continue to have the highest incidence, and the risk of infection has decreased in recent years.

Efeito da idade-período-coorte na mortalidade por câncer do colo do útero no Centro-Oeste do Brasil, 1980-2019 / Age-period-cohort effect on cervical cancer mortality in the Center-West of Brazil, 1980-2019 / Efecto edad-período-cohorte en la mortalidad por cáncer de cuello uterino en el Centro-Oeste de Brasil, 1980-2019

Objetivos: analisar o efeito da idade-período-coorte nas taxas de mortalidade por câncer do colo do útero no Centro-Oeste do Brasil. Métodos: estudo ecológico de séries temporais, de 1980 a 2019, cujas fontes de dados foram o Sistema de Informação sobre Mortalidade e as estimativas populacionais do Instituto Brasileiro de Geografia e Estatística. Modelos de efeito idade-período-corte com distribuição de Poisson foram usados. Resultados: observaram-se 19.260 óbitos, correspondente à taxa de mortalidade padronizada média de 17,23/100 mil mulheres. O efeito da idade indicou aumento progressivo das taxas com o avançar da idade. O efeito do período evidenciou redução do risco de morte no Distrito Federal (2015-2019), Mato Grosso do Sul (2010-2014) e Mato Grosso (2010-2019), além de aumento em Goiás (2015-2019). O efeito da coorte revelou aumento do risco de morte para as nascidas antes de 1950-1954 e redução nas gerações a partir de 1955-1959. Conclusão: há evidências de efeito da idade-período-coorte na mortalidade por câncer do colo do útero no Centro-Oeste brasileiro, o que demanda fortalecimento de ações para sua prevenção e controle voltadas para mulheres de coortes e idades sob maior risco de morrer por essa causa.

Objectives: to analyze the effect of age-period-cohort on cervical cancer mortality rates in the Center-West of Brazil. Methods: ecological time series study from 1980 to 2019, utilizing data from the Mortality Information System and population estimates from the Brazilian Institute of Geography and Statistics. Age-period-cohort effect models with Poisson distribution were employed. Results: 19,260 deaths were observed, corresponding to an average standardized mortality rate of 17.23/100,000 women. The age effect indicated a progressive increase in rates as age advanced. The period effect showed a reduction in the risk of death in the Federal District (2015-2019), Mato Grosso do Sul (2010-2014), and Mato Grosso (2010-2019), as well as an increase in Goiás (2015-2019). The cohort effect showed an increase in the risk of death for those born before 1950-1954 and a reduction in the generations from 1955-1959 onwards. Conclusion: there is evidence of an age-period-cohort effect on mortality from cervical cancer in the Brazilian Center-West, which calls for the strengthening of actions for its prevention and control aimed at women of cohorts and ages at greater risk of dying from this cause.

Tendência temporal da mortalidade por homicídios femininos por arma de fogo nos estados da região Nordeste do Brasil no período 2000-2019 / Temporal trends in female firearm homicides across states in the Northeast of Brazil during the period 2000-2019

Resumo O objetivo deste artigo é analisar a tendência temporal dos homicídios femininos perpetrados por arma de fogo nos estados nordestinos, no período de 2000 a 2019. Estudo ecológico, com dados de homicídios por arma de fogo em mulheres com 10 ou mais anos, registrados no Sistema de Informação Sobre Mortalidade. Os dados de mortalidade e os dados populacionais foram obtidos junto ao Departamento de Informática do Sistema Único de Saúde. Após a correção dos registros de óbito para qualidade e cobertura dos óbitos, as taxas de mortalidade foram calculadas Tendências foram avaliadas por regressão binomial negativa, classificadas de acordo com o valor do risco relativo e valor de p. Calculou-se a variação percentual anual média das taxas de mortalidade. A região apresentou 4,40 homicídios por arma de fogo por 100 mil mulheres no período do estudo, maiores coeficientes em Alagoas (5,40), na faixa etária de 15-19 anos (5,84), e via pública (1,58). As tendências foram ascendentes, com exceção de Pernambuco em que foi descendente, e estacionárias em Alagoas. Os homicídios por arma de fogo em via pública apresentaram maior percentual de aumento no período estudado. Observou-se tendência ascendente nos homicídios femininos perpetrados por arma de fogo na maioria dos estados nordestinos.

Abstract This article aims to analyze temporal trends in female firearm homicides in the Northeast of Brazil during the period 2000-2019. We conducted an ecological study using data on firearm homicides of women aged 10 years and over obtained from the Mortality Information System. The population data were taken from the 2010 Census. Homicide rates were calculated after correcting the data to account for differences in the quality and coverage of death records. Trends were assessed using negative binomial regression and described using relative risk and p values. Average annual percentage changes in homicide rates were also calculated. The regional firearm homicide rate during the study period was 4.40 per 100,000 women. Rates were highest in the state of Alagoas (5.40), the 15-19 age group (5.84) and in public thoroughfares (1.58). Trends were upward across all states except Pernambuco, where they were downward, and Alagoas, where rates were stationary. The place of occurrence with the highest percentage increase in firearm homicides over the study period was public thoroughfares. Female firearm homicides showed an upward trend across most northeastern states.

Efeitos de idade, período e coorte na mortalidade por câncer de próstata em homens no estado do Acre, oeste Amazônico brasileiro / Effects of age, period, and cohort on mortality by prostate cancer among men in the state of Acre, in the Brazilian Western Amazon

Resumo O objetivo foi analisar os efeitos de idade, período e coorte de nascimento na evolução temporal da mortalidade por câncer de próstata em homens no estado do Acre, no período de 1990 a 2019. Trata-se de um estudo ecológico de tendência temporal, que foi avaliada pelo método de joinpoint, estimando as variações percentuais anuais das taxas de mortalidade. Os efeitos idade-período-coorte de nascimento foram calculados pelo modelo de regressão de Poisson, utilizando as funções estimáveis. A taxa de mortalidade apresentou incremento de 2,20% (IC95%: 1,00-3,33) no período estudado. A mortalidade aumentou com a idade. Foi observado risco relativo (RR) de 0,67 (IC95%: 0,59-0,76) entre 2005 e 2009, de 0,76 (IC95%: 0,67-0,87) a partir de 2005 e de 1,44 (IC95%: 1,25-1,68) a partir de 2015. As coortes de 1910 a 1924 apresentaram redução do risco (RR < 1) quando comparadas à coorte de referência (1935). Quanto ao período, sugere-se que a instituição de políticas públicas e o estabelecimento de diretrizes podem ter auxiliado para maior acesso ao diagnóstico, em consonância com o efeito de coorte. Esses achados contribuem para melhor compreensão do cenário epidemiológico do câncer de próstata em regiões com condições socioeconômicas mais vulneráveis.

Abstract The present study aimed to analyze the effects of age, time period, and birth cohort on the temporal evolution of mortality rates due to prostate cancer in men from the state of Acre, Brazil, in the period of 1990 to 2019. This is an ecological study in which the temporal trend was evaluated by the joinpoint method, estimating the annual percentage variations of the mortality rates. The age-period-birth cohort effects were calculated by using the Poisson Regression method, using estimation functions. The mortality rates showed an increase of 2.20% (95%CI: 1.00-3.33) in the period studied, tended to increase with age. A relative risk (RR) of 0.67 (95%CI: 0.59-0.76) was observed between 2005 and 2009, 0.76 (95%CI: 0.67-0.87) from 2005 on, and 1.44 (95%CI: 1.25-1.68) from 2015 on. The cohorts from 1910 to 1924 presented a risk reduction (RR < 1), when compared to the reference cohort (1935). Regarding the time period, the creation of public policies and the establishment of guidelines are suggested as factors which may have contributed to more access to diagnosis, in consonance with the cohort effect. These findings can contribute to a better understanding of the epidemiological scenario of prostate cancer in regions that are more vulnerable in terms of socioeconomic conditions.

Description of vaccination coverage and hesitancy obtained by epidemiological survey of children born in 2017-2018, in Belo Horizonte and Sete Lagoas, Minas Gerais, Brazil / Descripción de la cobertura de vacuna y de las vacunaciones obtenidas por la encuesta epidemiológica de niños nacidos en 2017-2018, en Belo Horizonte y Sete Lagoas, Minas Gerais / Descrição da cobertura e da hesitação vacinal obtida por inquérito epidemiológico de crianças nascidas em 2017-2018, em Belo Horizonte e Sete Lagoas, Minas Gerais

ABSTRACT Objective To describe vaccination coverage and hesitation for the basic children's schedule in Belo Horizonte and Sete Lagoas, Minas Gerais state, Brazil. Methods Population-based epidemiological surveys performed from 2020 to 2022, which estimated vaccine coverage by type of immunobiological product and full schedule (valid and ministered doses), according to socioeconomic strata; and reasons for vaccination hesitancy. Results Overall coverage with valid doses and vaccination hesitancy for at least one vaccine were, respectively, 50.2% (95%CI 44.1;56.2) and 1.6% (95%CI 0.9;2.7), in Belo Horizonte (n = 1,866), and 64.9% (95%CI 56.9;72.1) and 1.0% (95%CI 0.3;2.8), in Sete Lagoas (n = 451), with differences between socioeconomic strata. Fear of severe reactions was the main reason for vaccination hesitancy. Conclusion Coverage was identified as being below recommended levels for most vaccines. Disinformation should be combated in order to avoid vaccination hesitancy. There is a pressing need to recover coverages, considering public health service access and socioeconomic disparities.

Racial inequalities in child vaccination and barriers to vaccination in Brazil among live births in 2017 and 2018: an analysis of a retrospective cohort of the first two years of life / Desigualdades raciales en la vacunación infantil y obstáculos para la vacunación en Brazil entre nacidos vivos en 2017 y 2018: análisis de uma cohorte retrospectiva de los dos primeros años de vida / Desigualdades raciais na vacinação infantil e nos obstáculos à vacinação no Brasil entre nascidos vivos em 2017 e 2018: análise de uma coorte retrospectiva dos dois primeiros anos de vida

ABSTRACT Objective To describe timely vaccination completion and obstacles in the first 24 months of life in Brazil, examining associations with maternal race/skin color. Methods Study participants were 37,801 children born in 2017 and 2018 included in the National Immunization Coverage Survey. We calculated prevalence and 95% confidence intervals for timely vaccine completeness and obstacles at 5, 12 and 24 months of life, according to maternal race/skin color. Associations were analyzed using logistic regression. Results 7.2% (95%CI 6.3;8.2) of mothers faced difficulties in taking their children to be vaccinated, and 23.4% (95%CI 21.7;25.1) were not vaccinated when taken. These proportions were 75% (95%CI 1.25;2.45) and 97% (95%CI 1.57;2.48) higher, respectively, among Black mothers. At least one vaccination was delayed among 49.9% (95%CI 47.8;51.9) and 61.1% (95%CI 59.2;63.0) of children by 5 and 12 months, respectively. These rates were higher among Black/mixed race mothers. Conclusion There are racial inequalities in both the obstacles faced and in vaccination rates in Brazil.

Longitudinal study of humoral immunity against SARS-CoV-2 of health professionals in Brazil: the impact of booster dose and reinfection on antibody dynamics.

Introduction: The pandemic caused by SARS-CoV-2 has had a major impact on health systems. Vaccines have been shown to be effective in improving the clinical outcome of COVID-19, but they are not able to fully prevent infection and reinfection, especially that caused by new variants. Methods: Here, we tracked for 450 days the humoral immune response and reinfection in 52 healthcare workers from Brazil. Infection and reinfection were confirmed by RT-qPCR, while IgM and IgG antibody levels were monitored by rapid test. Results: Of the 52 participants, 19 (36%) got reinfected during the follow-up period, all presenting mild symptoms. For all participants, IgM levels dropped sharply, with over 47% of them becoming seronegative by the 60th day. For IgG, 90% of the participants became seropositive within the first 30 days of follow-up. IgG antibodies also dropped after this period reaching the lowest level on day 270 (68.5 ± 72.3, p<0.0001). Booster dose and reinfection increased the levels of both antibodies, with the interaction between them resulting in an increase in IgG levels of 130.3 arbitrary units. Conclusions: Overall, our data indicate that acquired humoral immunity declines over time and suggests that IgM and IgG antibody levels are not associated with the prevention of reinfection.

Female Homicides in Brazil and Its Major Regions (1980-2019): An Analysis of Age, Period, and Cohort Effects.

The objective was to analyze the temporal effects of age, period, and cohort on mortality from all female homicides, and from female homicides and by firearms, in Brazil from 1980 to 2019. Data were accessed from Brazilian health records. There was an increase in the risk of death in the 2000s in the North and Northeast regions and a decrease in the Southeast, South, and Midwest. Younger women had a higher risk of death than women born between 1950 and 1954. The findings may be correlated with the inefficiency of the Brazilian state in protecting female victims of violence.

Temporal patterns, spatial risks, and characteristics of tegumentary leishmaniasis in Brazil in the first twenty years of the 21st Century.

BACKGROUND: Tegumentary leishmaniasis (TL) is a significant public health issue in Brazil. The present ecological study describes the clinical and epidemiological characteristics of TL cases reported in the country, and analyzes the spatial and temporal patterns of the incidences and risks of occurrence across the five geopolitical regions and 27 federative units. METHODOLOGY/PRINCIPAL FINDINGS: Data regarding new cases of TL notified between 2001 and 2020 were obtained from the Information System for Notifiable Diseases of the Brazilian Ministry of Health. Joinpoint and spatial and temporal generalized additive models were used to establish trends in the evolution of TL during the target period. The incidence rate for the entire period was 226.41 cases/100,000 inhabitants. All regions of Brazil showed trends of decreasing incidence rates, albeit with fluctuations at specific times, with the exception of the Southeast where rates have increased since 2014, most particularly in Minas Gerais state. The disease was concentrated predominantly in the North region, with Acre state leading the incidence rank in the whole country, followed by Mato Grosso (Midwest), Maranhão and Bahia (Northeast) states. The spatial distribution of the risk of TL occurrence in relation to the annual averages was relatively stable throughout the period. The cutaneous form of TL was predominant and cases most frequently occurred in rural areas and among men of working age. The ages of individuals contracting TL tended to increase during the time series. Finally, the proportion of confirmations by laboratory tests was lower in the Northeast. CONCLUSION/SIGNIFICANCE: TL shows a declining trend in Brazil, but its widespread occurrence and the presence of areas with increasing incidence rates demonstrate the persistent relevance of this disease and the need for constant monitoring. Our findings reinforce the importance of temporal and spatial tools in epidemiologic surveillance routines and are valuable for targeting preventive and control actions.

Comparison of diagnostic performance of RT-qPCR, RT-LAMP and IgM/IgG rapid tests for detection of SARS-CoV-2 among healthcare workers in Brazil.

BACKGROUND: COVID-19 has become a major public health problem after the outbreak caused by SARS-CoV-2 virus. Great efforts to contain COVID-19 transmission have been applied worldwide. In this context, accurate and fast diagnosis is essential. METHODS: In this prospective study, we evaluated the clinical performance of three different RNA-based molecular tests - RT-qPCR (Charité protocol), RT-qPCR (CDC (USA) protocol) and RT-LAMP - and one rapid test for detecting anti-SARS-CoV-2 IgM and IgG antibodies. RESULTS: Our results demonstrate that RT-qPCR using the CDC (USA) protocol is the most accurate diagnostic test among those evaluated, while oro-nasopharyngeal swabs are the most appropriate biological sample. RT-LAMP was the RNA-based molecular test with lowest sensitivity while the serological test presented the lowest sensitivity among all evaluated tests, indicating that the latter test is not a good predictor of disease in the first days after symptoms onset. Additionally, we observed higher viral load in individuals who reported more than 3 symptoms at the baseline. Nevertheless, viral load had not impacted the probability of testing positive for SARS-CoV-2. CONCLUSION: Our data indicates that RT-qPCR using the CDC (USA) protocol in oro-nasopharyngeal swabs samples should be the method of choice to diagnosis COVID-19.

The influence of the age-period-cohort effects on male suicide in Brazil from 1980 to 2019.

Suicide is a complex and multi-determined phenomenon. Higher rates are observed in men and are related to multiple risk factors, including mental disorders, financial crises, unemployment, and easy access to highly lethal means of perpetration, such as firearms. We studied the effects of age, period, and cohort (APC) on total and firearm-related suicides in men in Brazil and its major regions from 1980 to 2019. Death records were extracted from the Brazilian Ministry of Health's Mortality Information System. Estimable functions were used to estimate APC models, through the Epi library of the R statistical program, version 4.2.1. During the study period, Brazil had an average rate of 10.22 deaths per 100,000 men. Among regions, rates ranged from 8.62 (Northeast) to 16.93 (South). The same profile was observed in suicides by firearms. After estimating the APC models, we observed a temporal trend of increasing total suicides for Brazil and regions, except for the South region, where the trend was stationary. The trend was downward for firearm suicides for all locations. A positive gradient was observed in the mortality rate with advancing age for total suicides; and peak incidence between 20-29 years, with subsequent stabilization, for suicides perpetrated by firearms. There was a reduction in the risk of death for suicides perpetrated by firearms in relation to the reference period (1995-1999) for all locations, except in the North region, where the effect was not significant. The younger generations from the 1960s onwards had a higher risk of death from total suicide and a lower risk for those perpetrated by firearms in relation to the reference cohort (1950-1954). We observed a reduction in the mortality trend for suicides perpetrated by firearms, a reduction in the risk of death in the 2000s and for men born after 1960. Our results suggest reducing the risk of death from suicide by firearms in Brazil and regions. However, there is an upward trend in mortality from total suicides in the study period (1980-2019) and for younger cohorts.

Spatio-temporal relative risks and priority areas for visceral leishmaniasis control in Brazil, between 2001 and 2020.

Visceral leishmaniasis (VL) is a pressing public health problem in Brazil. The proper implementation of disease control programs in priority areas is a challenge for healthcare managers. The present study aimed to analyze the spatio-temporal distribution and identify high risk areas of VL occurrence in the Brazilian territory. We analyzed data regarding new cases with confirmed diagnosis of VL in Brazilian municipalities, from 2001 to 2020, extracted from the Brazilian Information System for Notifiable Diseases. The Local Index of Spatial Autocorrelation (LISA) was used to identify contiguous areas with high incidence rates in different periods of the temporal series. Clusters of high spatio-temporal relative risks were identified using the scan statistics. The accumulated incidence rate in the analyzed period was 33.53 cases per 100,000 inhabitants. The number of municipalities that reported cases showed an upward trend from 2001 onward, although there was a decrease in 2019 and 2020. According to LISA, the number of municipalities considered a priority increased in Brazil and in most states. Priority municipalities were predominantly concentrated in the states of Tocantins, Maranhão, Piauí, and Mato Grosso do Sul, in addition to more specific areas of Pará, Ceará, Piauí, Alagoas, Pernambuco, Bahia, São Paulo, Minas Gerais, and Roraima. The spatio-temporal clusters of high-risk areas varied throughout the time series and were relatively higher in the North and Northeast regions. Recent high-risk areas were found in Roraima and municipalities in northeastern states. VL expanded territorially in Brazil in the 21st century. However, there is still a considerable spatial concentration of cases. The areas identified in the present study should be prioritized for disease control actions.

Estudo exploratório acerca da prevalência do alto risco para eventos coronários na população brasileira: evidências da Pesquisa Nacional de Saúde 2013 / Exploratory study on the prevalence of high risk for coronary events in the Brazilian population: evidence from National Health Survey 2013

Resumo Introdução: As doenças do aparelho circulatório representam a principal causa de adoecimento e mortes na população mundial. Objetivo: Estimar a prevalência de alto risco para evento coronário (ARC) e os fatores associados na população adulta brasileira. Método: Estudo transversal, com base nos dados da Pesquisa Nacional de Saúde 2013. Para os indivíduos classificados em ARC, segundo a primeira fase de estratificação da I Diretriz Brasileira de Prevenção Cardiovascular, avaliou-se a associação dessa condição com variáveis sociodemográficas, condição de saúde e hábitos e estilo de vida. A análise estatística foi realizada em três etapas: descritiva, bivariada e múltipla. Consideraram-se os pesos amostrais e o efeito de desenho do plano de amostragem complexo, utilizando-se da biblioteca survey do programa estatístico R, versão 3.2.2. Resultados: A prevalência de ARC na população brasileira foi de 11,06% (IC95% 10,83-11,29). Observou-se maior proporção de ARC com o avançar da idade, em indivíduos residentes no centro-sul, que autoavaliaram a saúde como ruim/muito ruim, ex-fumantes e hipertensos. Conclusões: A população brasileira apresentou alta prevalência de ARC e, assim, possui mais de 20% de risco de um evento coronário agudo nos próximos dez anos, caso medidas de prevenção e controle não sejam tomadas.

Abstract Background: Diseases of the circulatory system are the leading cause of illness and death in the world population. Objective: Estimate the prevalence of high risk for coronary events (HRC) and associated factors in the Brazilian adult population. Method: This is a cross-sectional study, based on data from the National Health Survey 2013. The association of this condition with sociodemographic, health condition, and habits and lifestyle was evaluated for individuals as in HRC, according to the first stratification phase of the I Brazilian Directive of Cardiovascular Prevention. Statistical analysis was performed in three stages: descriptive; bivariate; and multiple analysis. Sampling weights and design effect of the complex sampling plan were considered, using the survey library of the statistical program R, version 3.2.2. Results: The prevalence of HRC in the Brazilian population was 11.06% (95%CI 10.83-11.29). A higher prevalence of HRC was observed with advancing age, in individuals living in the Central-South, who self-rated their health as poor/very poor, former smokers, and individuals with systemic arterial hypertension. Conclusions: The Brazilian population presented a high prevalence of HRC and, thus, has a more than 20% risk of an acute coronary event in the next ten years, if prevention and control measures are not taken.

Laboratory profile after mining dam breach: Brumadinho Health Project results.

OBJECTIVE: To evaluate changes in selected laboratory tests in the population included in the Brumadinho Health Project, according to the exposure to the dam failure. METHODS: Cross-sectional study carried out on representative sample of residents (≥12 years) in Brumadinho, Minas Gerais, including: 1) non-exposed; 2) directly affected by tailings sludge; 3) residents in mining area. The prevalence of abnormal results of blood count, total, HDL and LDL cholesterol, triglycerides, aspartate aminotransferase, alanine aminotransferase, creatinine, urea, estimate of glomerular filtration rate (eGFR) and high-sensitivity C-reactive protein (hs-CRP) were estimated. The Prevalence Ratios (PR) and 95% Confidence Intervals (95%CI) of having an abnormal laboratory finding were estimated using Generalized Linear Models with Poisson probability distribution. Crude and adjusted models were estimated for age range, gender, diabetes, body mass index, smoking, hypertension. RESULTS: After adjusting, there was no difference in PR between the three populations for most tests, with the exception of the population residing in an area with mining activity and not directly affected by the mud, with a lower chance of having altered total cholesterol (PR: 0.84; 95%CI 0.74-0.95) and a higher chance of having altered HDL cholesterol (PR: 1.26; 95%CI 1.07-1.50), hs-CRP (PR: 1.19; 95%CI 1.04-1.37), and eGFR <60mL/min/1,73 m2 (PR: 1.51; 95%CI 1.05-2.19). CONCLUSION: No significant differences were found in the prevalence of biochemical and hematological alterations between the populations directly exposed and not exposed to tailings. Only the group residing in the mining area had a higher prevalence of alterations related dyslipidemia, renal disease, and inflammation.

ArboAlvo: stratification method for territorial receptivity to urban arboviruses.

OBJECTIVE: To present the urban arboviruses (dengue, zika and chikungunya) stratification methodology by the territorial receptivity Index, an instrument for the surveillance and control of these diseases, which considers the heterogeneity of an intra-municipal territory. METHODS: Ecological study that uses as unit of analysis the areas covered by health centers in Belo Horizonte. For the development of a territorial receptivity index, indicators of socio-environmental determination of urban arboviruses were selected in order to integrate the analysis of main components. The resulting components were weighted by the analytic hierarchy process and combined via map algebra. RESULTS: The territorial receptivity index showed great heterogeneity of urban infrastructure conditions. The areas classified with high and very high receptivity correspond to approximately 33% of the occupied area and are mainly concentrated in the administrative planning regions of East, Northeast, North, West, and Barreiro, especially in areas surrounding the municipality. When the density of dengue cases and Aedes eggs, from 2016, were superimposed with the stratification by the index of territorial receptivity to urban arboviruses, areas of very high receptivity had a high density of cases and Aedes eggs - higher than that observed in other areas of the city, which corresponds to a very small percentage of the municipal territory (13.5%). CONCLUSION: The analyses indicate the need for the development of adequate surveillance and control actions for each context, overcoming the logic of homogeneous allocation throughout the territory.

Inequalities in Temporal Effects on Cervical Cancer Mortality in States in Different Geographic Regions of Brazil: An Ecological Study.

Cervical cancer is a public health issue with high disease burden and mortality in Brazil. The objectives of the present study were, firstly, to analyze age, period, and cohort effects on cervical cancer mortality in women 20 years old or older from 1980 to 2019 in the North, South, and Southeast Regions of Brazil; and secondly, to evaluate whether the implementation of a national screening program and the expansion of access to public health services impacted the examined period and reduced the risk of death compared with previous years and among younger cohorts. The effects were estimated by applying Poisson regression models with estimable functions. The highest mortality rate per 100,000 women was found in Amazonas (24.13), and the lowest in São Paulo (10.56). A positive gradient was obtained for death rates as women's age increased. The states in the most developed regions (South and Southeast) showed a reduction in the risk of death in the period that followed the implementation of the screening program and in the cohort from the 1960s onwards. The North Region showed a decreased risk of death only in Amapá (2000-2004) and Tocantins (1995-2004; 2010-2019). The findings indicate that health inequities remain in Brazil and suggest that the health system has limitations in terms of decreasing mortality associated with this type of cancer in regions of lower socioeconomic development.

Differences in prescribed medicine availability in Primary Health Care: evidence from the Prover Project. / Diferenças na disponibilidade de medicamentos prescritos na Atenção Primária: evidências do Projeto Prover.

This is a cross-sectional study on the availability of prescribed medicines in Primary Health Care (PHC), with a probabilistic sample of 1,221 users of public pharmacies in a health pole municipality in Minas Gerais, in 2017. Medicine availability indicators were estimated, and a hierarchical logistic regression was performed, according to the behavioral model of health service use. Only 39.3% of patients received all medicines in the prescribed quantities. The most and the least available medicines were, respectively, those for the digestive system/metabolism, and for blood and hematopoietic organs. Full availability of the prescribed treatment was associated with higher schooling (≥ 8 years OR: 1.7; 95% CI: 1.3-2.4); proximity to the pharmacy (≤15 min OR: 1.7; 95% CI: 1.2-2.3); absence of out-of-pocket expenditure on medicines (OR: 2.2; 95% CI: 1.7-2.9), and a smaller number of prescription drugs (≤ 2 OR: 3.2; 95% CI: 2.3-4.4; 3/4 OR: 1.6; 95% CI: 1.2-2.1). These results showed differences in medicine availability within the Brazilian Unified Health System (SUS), and highlighted the need to reorganize the dispensing services network and pharmaceutical procurement planning, as well as to develop public policies to protect the vulnerable population.

Estudo transversal da disponibilidade de medicamentos prescritos na Atenção Primária, com amostra probabilística de 1221 usuários das farmácias públicas de município polo de saúde em Minas Gerais, em 2017. Foram estimados indicadores de disponibilidade dos medicamentos e realizou-se regressão logística hierárquica, segundo o modelo comportamental de uso de serviços de saúde. Apenas 39,3% dos usuários receberam todos os medicamentos nas quantidades prescritas. Os medicamentos mais e menos disponíveis foram, respectivamente, os que atuam no sistema digestivo/metabolismo, e no sangue e órgãos hematopoiéticos. A disponibilidade integral do tratamento se mostrou associada a mais escolaridade (≥ 8 anos OR: 1,7; IC 95%: 1,3-2,4); proximidade até a farmácia (≤15 min OR: 1,7; IC 95%: 1,2-2,3); ausência de gastos privados com medicamentos (OR: 2,2; IC 95%: 1,7-2,9) e menor número de medicamentos prescritos (≤ 2 OR: 3,2; IC 95%: 2,3-4,4; 3/4 OR: 1,6; IC 95%: 1,2-2,1). Esses resultados mostram diferenças na disponibilidade de medicamentos dentro do SUS, evidenciando a necessidade de reorganização da rede de atendimento dos serviços de dispensação e do planejamento das aquisições de medicamentos, além da proposição de políticas públicas que priorizem a população mais vulnerável.

Mudanças no acesso gratuito a medicamentos prescritos no sistema público de saúde no Brasil / Changes in the free access to prescribed medicines in the public health system in Brazil

Resumo Introdução Os medicamentos são a intervenção terapêutica mais utilizada e a mais custo efetiva para o tratamento de diversas patologias. A falta de acesso a medicamentos entre grupos com menores condições socioeconômicas representa uma iniquidade nos cuidados com a saúde. Nesse sentido, o fornecimento gratuito de medicamentos pelo setor público é essencial para a promoção da equidade. Objetivo Avaliar a mudança, no tempo, da prevalência de acesso gratuito, pela população adulta brasileira, a medicamentos prescritos no Sistema Único de Saúde (SUS) ao longo de 10 anos. Método Análise dos dados, por regressão logística, das Pesquisas Nacionais por Amostra de Domicílios (PNAD) realizadas no Brasil em 1998, 2003 e 2008. A variável de interesse foi o acesso gratuito a medicamentos prescritos. Resultados O acesso gratuito a medicamentos pelo Sistema Único de Saúde aumentou ao longo do tempo. Indivíduos com renda socioeconômica mais baixa tiveram maior chance de acesso a medicamentos e esse cenário se manteve constante ao longo dos anos avaliados. Conclusão Os achados revelam a importância do SUS como ferramenta efetiva para a promoção do acesso a medicamentos, especialmente para os indivíduos mais pobres. Entretanto, a redução da desigualdade no acesso a medicamentos permanece como desafio.

Abstract Background The medicines are the most used and most effective therapeutic intervention for the treatment of various pathologies. The lack of access to medicines among groups with lower socioeconomic conditions represents an inequity in health care. In this sense, the public supply of medicines is free of charge by the public sector to promote equity. Objective To evaluate the change, in time and prevalence of free access, by the Brazilian adult population, to medicines prescribed in the Unified Health System (SUS) over 10 years. Method Data came from the National Household Sample Surveys (PNAD) conducted in Brazil in 1998, 2003 and 2008. The dependent variable was free access to prescribed medicines. Results Free access to medicines in the SUS increased over time. Individuals with lower socioeconomic income had higher chance to access the medicines and this scenario remained constant over the years evaluated. Conclusion The findings reveal the importance of SUS as an effective tool for promoting access to medicines, especially for the poorest individuals. However, reducing inequality in access to medicines remains a challenge.
