ABSTRACT

Resumo O objetivo deste estudo é detectar as áreas de maior risco para óbitos de crianças e adolescentes de 5 a 14 anos no estado de Mato Grosso entre os anos de 2009 e 2020. Estudo ecológico, tipo exploratório, cuja unidade de análise foram os municípios. Considerando dados de mortalidade do SIM e os demográficos do IBGE, o estudo utilizou a estatística multivariada para a identificação dos clusters espaço-temporais de sobrerrisco de mortalidade nesta faixa etária. Dos 5 aos 9 anos, dois clusters de alto risco de mortalidade foram detectados; o mais provável localizado na mesorregião sul (RR: 1,6; LRV: 8,53). Dentre os 5 clusters detectados na faixa etária dos 10 aos 14 anos, o principal foi localizado na mesorregião norte (RR: 2,26; LRV: 7,84). Foi identificada redução das taxas de mortalidade na faixa etária mais jovem e aumento destas taxas na faixa etária mais velha. A identificação destes clusters, cuja análise merece ser replicada a outras partes do território nacional, é a etapa inicial para a investigação de possíveis fatores associados à morbi-mortalidade deste grupo ainda pouco explorado e para o planejamento de intervenções adequadas.


Abstract The study aimed to detect high-risk areas for deaths of children and adolescents 5 to 14 years of age in the state of Mato Grosso, Brazil, from 2009 to 2020. This was an exploratory ecological study with municipalities as the units of analysis. Considering mortality data from the Mortality Information System (SIM) and demographic data from the Brazilian Institute of Geography and Statistics (IBGE), the study used multivariate statistics to identify space-time clusters of excess mortality risk in this age group. From 5 to 9 years of age, two clusters with high mortality risk were detected; the most likely located in the state's southern mesoregion (RR: 1.6; LRT: 8,53). Among the 5 clusters detected in the 10-14-year age group, the main cluster was in the state's northern mesoregion (RR: 2,26; LRT: 7,84). A reduction in mortality rates was observed in the younger age group and an increase in these rates in the older group. The identification of these clusters, whose analysis merits replication in other parts of Brazil, is the initial stage in the investigation of possible factors associated with morbidity and mortality in this group, still insufficiently explored, and for planning adequate interventions.

ABSTRACT

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.

ABSTRACT

The present study characterized the cattle movement network in the state of Goiás, Brazil, in the period from 2010 to 2016, by identifying the areas of greatest flow and the purposes for which these animals were moved. For this, an analysis of the data referring to 4,697,239 animal transit guides (GTA), specifically for bovines, issued between the years 2010 to 2016 was carried out. Data such as the number of animals transported, origin and destination, as well as purpose of movement (slaughter, finishing, reproduction, post-weaning, auctions, sports, exhibitions, exports, and others) were evaluated. The data were subjected to descriptive analysis, in which the animal movements were divided into quartiles. There was an intense movement of cattle throughout the state, mainly for the purposes of finishing and slaughter. Identifying the areas with the highest flow of animals, such as the northwest and south regions, is an important tool for planning actions and applying preventive measures against the spread of infectious agents through the territory of Goiás.


No presente estudo, foi caracterizada a rede de trânsito de bovinos no estado de Goiás, Brasil, durante o período de 2010 a 2016, identificando-se as áreas de maior fluxo e as finalidades do trânsito desses animais. Para isso, foi realizada uma análise dos dados referentes a 4.697.239 guias de trânsito animal (GTA), especificamente de bovinos, emitidas entre os anos de 2010 a 2016. Avaliaram-se informações como número de animais transitados, origem e destino, bem como finalidade de movimentação desses animais (abate, engorda, reprodução, recria, leilão, esporte, exposição, exportação, entre outras). Os dados foram submetidos à análise descritiva, optando-se pela divisão da movimentação animal em quartis. Observou-se haver trânsito intenso de bovinos em todo o estado, principalmente com a finalidade de engorda, recria e abate. A identificação das áreas que apresentam maior fluxo de animais, como as regiões noroeste e sul, torna-se uma importante ferramenta no planejamento das ações e na aplicação de medidas preventivas contra a disseminação de agentes infecciosos pelo território goiano.

ABSTRACT

Southern Brazil concentrates a considerable number of cases of cutaneous leishmaniasis reported since 1980, and Paraná is the state that most records CL cases in the region. The main sand fly species incriminated as vectors of Leishmania (Viannia) braziliensis (Vianna,1911) are Migonemyia (Migonemyia) migonei (França, 1920), Nyssomyia (Nyssomyia) neivai (Pinto, 1926) and Nyssomyia (Nyssomyia) whitmani (Antunes & Coutinho, 1936). In this study, we evaluated areas with climatic suitability for the distribution of these vectors and correlated these data with CL incidence in the state. The occurrence points of Mg. migonei, Ny. neivai, and Ny. whitmani were extracted from a literature review and field data. For CL analysis in the state of Paraná, data were obtained from the Informatics Department of the Unified Health System of Brazil (DATASUS), covering the period from 2001 to 2019. The layers of bioclimatic variables from the WorldClim database were used in the study. Species distribution modeling was developed using the MaxEnt Software version 3.4.4. ArcGIS software version 10.5 was used to develop suitability maps and the graphical representation of disease incidence. The AUC values were acceptable for all models (> 0,8). Bioclimatic variables BIO13 and BIO14 were the most influential in the distribution of Mg. migonei, while BIO19 and BIO6 were the variables that most influenced the distribution of Ny. neivai, and Ny. whitmani was most influenced by variables BIO5 and BIO9. During 19 years, 4992 cases of CL were reported in the state by 286 municipalities (71,6%). Northern Paraná showed the highest number of areas with very high and high climatic suitability for the occurrence of these species, coinciding with the highest number of CL cases. The modeling tools allowed analyzing the association between climatic variables and the geographical distribution of CL in the state. Moreover, they provided a better understanding of the climatic conditions related to the distribution of different species, favoring the monitoring of risk areas, the implementation of preventive measures, risk awareness, early and accurate diagnosis, and consequent timely treatment.

ABSTRACT

RESUMEN En Ecuador las especies exóticas invasoras (EEI) provocan consecuencias negativas en los aspectos ecológicos, económicos y de seguridad alimentaria. Los agroecosistemas hacen parte de los sectores productivos a nivel mundial, pero son vulnerables a sufrir invasiones biológicas por la constante actividad humana y por el traslado de vegetación, tierra y semillas, por lo que deben ser constantemente monitoreados, pues desempeñan un papel importante en la economía al ser fuente de empleo. El objetivo de esta investigación fue evaluar la influencia potencial de las EEI sobre los agroecosistemas de Ecuador continental a través del modelado del nicho ecológico. Se usó como método de modelación el algoritmo de máxima entropía y se emplearon los registros de presencia de seis especies de plantas, tres insectos y un molusco en sus regiones nativas y en zonas invadidas a nivel mundial. Los registros provienen de Global Biodiversity Information Facility y de Tropicos. Como variables explicativas se emplearon 19 variables bioclimáticas y seis variables de vegetación. Se obtuvieron los mapas de distribución geográfica potencial, las áreas de superposición de la distribución de las especies y la delimitación de las zonas de mayor riesgo. Se determinó que las condiciones ambientales de las regiones Sierra y Amazónica son idóneas para una posible invasión de seis y siete especies. Además, más del 50 % de la cobertura agropecuaria del país podría ser afectada por las especies Wasmannia rochai, Spondias purpurea L., Lissachatina fúlica y Conium maculatum L., siendo los cultivos de ciclo corto los más vulnerables a la invasión por estas especies.


ABSTRACT In Ecuador, invasive alien species (IAS) cause negative consequences in ecology, economy, and food security. Agroecosystems belong to one of the productive sectors worldwide but are vulnerable to biological invasions by constant human activity and the transfer of vegetation, soil, and seeds, so they must be constantly monitored because of their important role in the economy to be a source of employment. The objective of this research was to evaluate the potential influence of IAS on the agroecosystems of continental Ecuador through the modeling of the ecological niche. The maximum entropy algorithm was used as a modeling method, and the presence register in the native region and invaded areas at a global level of six plant species, three insect species and one mollusc species were used. Data were obtained from the Global Biodiversity Information Facility and Tropicos. As explanatory variables, 19 bioclimatic variables, and six vegetation variables were used. Maps of potential geographical distribution, the overlap areas of the distribution of the species, and the delimitation of the zones of greater risk were obtained. It was determined that the environmental conditions of the Sierra and the Amazonian regions are ideal for a possible invasion of most species. Moreover, more than 50 % of the agricultural coverage of the country could be affected by Wasmannia rochai, Spondias purpurea L., Lissachatina fulica, and Conium maculatum L., with short cycle crops being the most vulnerable to invasion.

ABSTRACT

Objetivo: describir la distribución espacial y temporal de los virus del dengue, zika y Chikungunya en Colombia e identificar si existe agregación espacial, temporal y espacio-temporal. Métodos: se desarrolló un estudio descriptivo de la distribución espacial y temporal de los virus del Dengue (2006-2017), Zika (2015-2017) y Chikungunya (2014-2017) en Colombia, utilizando los principios de la estadística espacial, específicamente en el análisis exploratorio de datos espaciales. Resultados: se identificaron zonas de Colombia donde se presenta una mayor densidad y prevalencia de casos. A partir de los 1124 municipios analizados para cada evento (casos de Dengue, Zika y Chikungunya), se comprobó con significancia estadística (p<0.05) la existencia de dos conglomerados espacio-temporales, en la zona sur-occidental de la región andina y en la región de la Orinoquia. Conclusiones: Se demostró la existencia de dos conglomerados para los eventos Dengue, Zika y Chikungunya que podría establecerse como zonas de mayor riesgo de co-infección.


Objective: to describe the spatial and temporal distribution of dengue, zika and Chikungunya viruses in Colombia and to identify clusters at spatial, temporal and space-temporal levels. Methods: A descriptive study was developed about the space and time distribution of the Dengue virus (2006-2017), Zika (2015-2017) and Chikungunya (2014-2017) in Colombia, using principles of spatial statistics, namely the spatial data exploratory analysis. Results: Areas of Colombia were identified where there is a higher density and prevalence of cases and were analyzed 1124 municipalities for each event (cases of Dengue, Zika and Chikungunya). Significant clusters (P<0.05) were proven in spatial, temporal and space-temporal analysis, in the south-western zone of the Andean region and in the Orinoquia region. Conclusions: Two conglomerates were confirmed for the Dengue, Zika and Chikungunya events, that could be established as areas of higher risk of co-infection.

ABSTRACT

A Hanseníase ainda é um problema para a saúde pública e um desafio para os países endêmicos, principalmente em regiões de fronteira, onde o fluxo migratório é intenso. O estudo tem como objetivo identificar as áreas de risco para a ocorrência da hanseníase e verificar sua relação com os determinantes sociais em Foz do Iguaçu-PR. Estudo ecológico que considerou os casos novos de hanseníase notificados no município de Foz do Iguaçu no período de 2003 a 2015 e as unidades de análise foram os setores censitários urbanos. Foi realizada análise descrita dos casos novos. Em sequência, para a identificação das áreas de risco para a ocorrência da hanseníase utilizou-se a Estatística de varredura espacial e espaçotemporal e para identificação das áreas de risco para incapacidades, recorreu-se a varredura espacial e ao Estimador de intensidade Kernel. A investigação da dependência espacial foi verificada através do Moran Global, Getis-Ord G e Gi*. O Índice de Moran Bivariado Global (IMBG), Regressão por Mínimo Quadrados (OLS) e Regressão Geograficamente Ponderada (GWR) foi utilizada para verificar a associação dos determinantes sociais e o risco de adoecimento por hanseníase. Foram notificados 840 casos, onde a taxa de detecção de casos novos em homens foi 25,6/100.000 hab. e 24,9/100.000 hab. para mulheres, houve predomínio da raça/cor amarela (78,6/100.000 hab.), faixa etária >=60 anos (71,5/100.000 hab.) e ensino fundamental incompleto (60/100.000 hab.). As áreas de risco para a hanseníase e incapacidade grau 2 se concentraram no Distrito Sanitário Sul, Leste, Norte e Nordeste do município; regiões estas, caracterizadas por alta densidade populacional e pobreza. Os determinantes sociais renda (IMBG: 0,1273; p=0,001), número de moradores (IMBG: 0,0703; p=0,008), domicílios sem saneamento básico (IMBG: 0,0743; p= 0,025), pessoas da raça/cor preta (IMBG: 0,0397; p= 0,04), parda (IMBG: 0,1017; p= 0,002) e indígena (IMBG: 0,0976; p= 0,005) apresentaram correlativa positiva com o risco de hanseníase. As análises de regressão revelaram que a proporção de domicílios com renda mensal domiciliar per capita maior de um salário mínimo (? = 0,025, p = 0,036) apresenta risco menor de adoecimento por hanseníase. Enquanto, as pessoas de raça/cor parda (? = -0,101, p = 0,024) apresentam maior risco de adoecimento por hanseníase. Os resultados do estudo apontam que existe associação entre os determinantes sociais e o risco de adoecimento por hanseníase no município investigado. O investimento em políticas públicas para melhoria de distribuição de renda pode favorecer a mudança deste quadro. Os achados podem contribuir para nortear ações em saúde que auxiliem no combate e controle da hanseníase nesta região de fronteira


Leprosy is still a public health problem and a challenge for endemic countries, especially in border regions where migration flows are intense. The study aims to identify the risk areas for the occurrence of leprosy and to verify its relation with the social determinants in Foz do Iguaçu-PR. An ecological study that considered the new cases of leprosy reported in Foz do Iguaçu from 2003 to 2015 and the units of analysis were the urban census sectors. A descriptive analysis of the new cases was performed in order to identify the risk areas for the occurrence of leprosy, the spatial and time-spacial scanning statistics were used and the spatial scan and Kernel intensity estimator were used to identify areas of risk for disabilities. The investigation of spatial dependence was verified through Global Moran, Getis-Ord G and Gi *. The Global Bivariate Moran Index (IMBG), Minimum Squares Regression (OLS) and Geographically Weighted Regression (GWR) were used to verify the association of social determinants and the risk of illness due to leprosy. 840 cases were reported, where the detection rate of new cases in men was 25.6/100,000 inhabitants and 24.9/100,000 inhabitants for women, there was a predominance of yellow color / race (78.6/100,000 inhabitants), age group >=60 years (71.5/100,000 inhabitants) and incomplete elementary school (60/100,000 inhabitants). Areas at risk for leprosy and degree of disability 2 were concentrated in the South, East, North and Northeast Health District of the city; regions, characterized by high population density and poverty. The social determinants of income (IMBG: 0.1273, p = 0.001), number of residents (IMBG: 0.0703, p = 0.008), households without basic sanitation (IMBG: 0.0743, p = 0.025) (IMBG: 0.0976, p = 0.04), black color/race (IMBG: 0.1017, p = 0.002) and native color/race (IMBG: 0.0976; p = 0.005) presented a positive correlation with the risk of leprosy. The regression analysis revealed that the proportion of households with monthly household income per capita greater than a minimum wage (? = 0.025, p = 0.036) had the lowest risk of illness due to leprosy. While people of black race/color (? = -0.101, p = 0.024) are at higher risk of illness due to leprosy. The results of the study indicate that there is an association between the social determinants and the risk of illness due to leprosy in the city under investigation. The investment in public policies to improve income distribution can favor the change of this framework. The findings may contribute to health actions that help combat and control leprosy in this border region

ABSTRACT

A leptospirose é uma grave zoonose associada às áreas de baixa renda dos centros urbanos. Embora roedores urbanos sejam considerados como principal reservatório para a leptospirose, o cão também pode desenvolver a doença e se tornar carreador assintomático. O objetivo do presente trabalho foi utilizar a metodologia estatística baseada na teoria de processos pontuais espaciais, buscando identificar a forma como se distribuem os cães sororreagentes para a leptospirose e seus determinantes de risco em uma vila na cidade de Curitiba. A análise do modelo possibilitou identificar as regiões de sobre-risco, onde o risco de soropositividade canina à leptospirose é significativamente maior. A relação significativa do efeito espacial no desenvolvimento da doença, além das variáveis estudadas, revela que não apenas um, mas a ação conjunta dos fatores relacionados ao animal, ao proprietário e ao ambiente influencia o risco maior da doença nos locais de maior efeito espacial. O resultado da análise indica claramente os territórios em maior risco na região da Vila Pantanal, possibilitando o planejamento de ações mais específicas e dirigidas a essas áreas em um contexto de vigilância da saúde.


Leptospirosis is a serious zoonotic disease associated to low income areas of urban settings. Although rodents are considered the main reservoir for urban leptospirosis, dogs may also develop the disease and become asymptomatic carriers. The objective of this study was to apply a statistical method based on the spatial point processes theory for canine leptospirosis to identify how seroreagents dogs are spatially distributed and their risk determinants in a village of Curitiba city. The model analysis allowed the identification of over-risk regions, where seropositivity risk for canine leptospirosis was significantly higher, revealing that not just one, but the combination of animal, owner and environment factors influenced the disease risk within areas with greater spatial effect. Analysis of results clearly identified the highest risk areas in the Pantanal Village, allowing the establishment of more specific preventive actions and focused on risk areas as priority for public health surveillance.

ABSTRACT

INTRODUCTION: Leptospirosis is a zoonotic disease, the primary hosts of which are wild, synanthropic, and household animals. Humans behave as terminal and accidental hosts. The prevalence of leptospirosis depends on carrier animals that disseminate the agent, on the environmental survival of this agent, and on the contact of susceptible individuals. Each serovar has one or more hosts with different adaptation levels. The focuses of leptospirosis are infected, sick, and asymptomatic animals, which are considered to be sources of environmental infection. This study aimed to determine the risk areas for leptospiral infection in stray dogs and patients diagnosed with leptospirosis from 2006 to 2008 in Maringá, State of Paraná, Brazil. METHODS: Three hundred and thirty-five stray dogs and 25 patients were studied. Serum from both animals and patients was examined by the microscopic serum agglutination test to study anti-leptospiral antibodies. To determine the risk areas and the spatial distribution of the disease, thematic maps were designed. RESULTS: Forty-one (12.2 percent) dogs positive for one or more leptospire serovars were observed, the most frequent serovars being Pyrogenes (43.9 percent), Canícola (21.9 percent), and Copennhageni (19.5 percent). Among the humans, 2 (8 percent) were positive for serovars Pyrogenes and Hardjo Prajitno and for Pyrogenes and Cynopteri. CONCLUSIONS: Spatial analysis showed that the risk for dogs and humans in the City of Maringá to become infected with leptospires exists in both the central and the peripheral areas, a fact that reinforces the relevance of this study and of continuous epidemiological and environmental surveillance actions to control the disease in animals and in humans.


INTRODUÇÃO: Leptospirose é uma zoonose que tem como hospedeiros primários os animais silvestres, sinantrópicos e domésticos. Os humanos comportam-se como hospedeiros terminais e acidentais. Sua prevalência depende dos animais portadores que disseminam o agente, de sua sobrevivência ambiental e do contato de pessoas susceptíveis. Cada sorovar tem um ou mais hospedeiros com diferentes níveis de adaptação. Os focos de leptospirose devem-se aos animais infectados, doentes e assintomáticos, considerados como fontes de infecção ambiental. O objetivo deste estudo foi determinar áreas de risco da infecção leptospírica em cães errantes e pacientes com diagnóstico de leptospirose nos anos de 2006 a 2008, em Maringá, Estado do Paraná, Brasil. MÉTODOS: Foram estudados 335 cães errantes e 25 pacientes. Os soros, tanto dos animais como dos pacientes, foram examinados pela prova de soroaglutinação microscópica (SAM), para pesquisa de anticorpos antileptospíricos. Para determinar áreas de risco e a distribuição espacial da doença foram elaborados mapas temáticos. RESULTADOS: Foram observados 41(12,2 por cento) cães positivos para um ou mais sorovares de leptospiras, e os mais frequentes foram: Pyrogenes (43,9 por cento), Canícola (21,9 por cento) e Copennhageni (19,5 por cento). Nos humanos, a positividade foi de 2 (8 por cento) para os sorovares, Pyrogenes e Hardjo Prajitno e, Pyrogenes e Cynopteri. CONCLUSÕES: A análise espacial revelou que o risco de cães e humanos, no município de Maringá, se infectar com leptospiras está presente tanto em áreas centrais como periféricas, fato que reforça a relevância deste estudo e de ações contínuas de vigilância epidemiológica e ambiental para o controle da doença tanto nos animais como no homem.

ABSTRACT

INTRODUÇÃO: No Tocantins, a malária apresenta comportamento diferenciado entre as microrregiões, com predominância dos casos importados. Este estudo descreve a análise espacial da malária no estado, no período de 2003 a 2008, buscando identificar nas microrregiões a incidência de casos autóctones e importados, bem como a procedência destes últimos. MÉTODOS: Trata-se de um estudo retrospectivo, pautado em dados secundários, que teve como fonte de dados o Sistema de Informações de Vigilância Epidemiológica - Malária (SIVEP-Malária), analisados através dos softwares estatísticos Epi Info versão 3.5.1. e Bioestat versão 5.0. RESULTADOS: Constatou-se que a malária não teve distribuição homogênea em todos os municípios. A área de maior prioridade agregou municípios localizados nas microrregiões oeste do estado, fronteira com o Pará, onde também se concentram o maior número de casos autóctones. A associação entre os casos autóctones e importados e as espécies de Plasmodium mostrou uma diferença estatisticamente significativa (G = 54,25; p < 0,0001). Das oito microrregiões, Miracema do Tocantins, Araguaína e Bico do Papagaio agruparam 75,8 por cento dos casos, e nessas, onze municípios se sobressaíram. Quanto à procedência, o Estado do Pará apresentou ampla distribuição com 85,5 por cento do total, seguido por Guiana Francesa com 7,4 por cento. CONCLUSÕES: Os resultados demonstraram a predominância dos casos importados e a diferença entre os municípios e microrregiões, apontando pela influencia de estados vizinhos na determinação das áreas de maior risco. Esses dados são importantes, pois contribuem para orientação e direcionamento das políticas públicas para o agravo no Tocantins.


INTRODUCTION: In Tocantins, the behavior of malaria differs between microregions, with predominance of imported cases. This study describes a spatial analysis on malaria in the state covering 2003 to 2008, which sought to identify the incidence of autochthonous and imported cases, and the origin of the latter, in the microregions. METHODS: This was a retrospective study using secondary data. The data source was the epidemiological surveillance information system for malaria (SIVEP-Malária), and the data were analyzed using the Epi Info version 3.5.1 and Bioestat version 5.0 statistical software. RESULTS: It was found that malaria was not homogeneously distributed in all municipalities. The area of highest priority comprised municipalities located in microregions in the west of the state, at the border of Pará, which also had the highest number of autochthonous cases. The association between the autochthonous and imported cases and the Plasmodium species showed a statistically significant difference (G = 54.25; p < 0.0001). Among the eight microregions, Miracema do Tocantins, Araguaína and Bico do Papagaio accounted for 75.8 percent of the cases and, among these, eleven municipalities stood out. Regarding provenance, the State of Pará showed widespread distribution with 85.5 percent of the total, followed by French Guiana with 7.4 percent. CONCLUSIONS: These results demonstrated the predominance of imported cases and the difference between municipalities and microregions, and showed the influence of neighboring states in determining the areas of greatest risk. These data are important, since they contribute towards guiding and directing public policies regarding this disease in Tocantins.
