Abstract The Pantanal is the largest seasonal freshwater wetland on Earth, characterized by the seasonal flooding and complex mosaic vegetation, which determines its biodiversity. Among this biodiversity, dung beetles (Coleoptera: Scarabaeidae: Scarabaeinae) are a group of insects that perform important ecological functions, such as: nutrient cycling, seed dispersion and parasite control. In order to mitigate the lack of information on dung beetle fauna of the Brazilian Pantanal, we conducted a bibliographic search of virtually all literature published until november-2020 on dung beetles sampled in the Pantanal. In addition, we had accessed to the records the largest collection of the dung beetle species from Brazilian Pantanal. We recorded 68 dung beetle species of 30 genera. The genera Canthon Holffmanseg 1847 is the most diverse with 13 species recorded. Although our knowledge about the dung beetle fauna in this ecosystem is still incipient, our results demonstrated a high richness of dung beetles in the Brazilian Pantanal. In addition, our study provides first list of dung beetle species and an illustrated dichotomy key to identify genera and some species occurring in the Brazilian Pantanal. Thus, the use of this guide for identification of dung beetle species and a list of species can be important tools to help researchers and provide incentive for new inventories on dung beetle fauna in the Brazilian Pantanal.

Resumo O Pantanal é a maior área úmida sazonal de água doce Neotropical da Terra, caracterizada pelas inundações sazonais e pela complexa vegetação em mosaico, que determina sua biodiversidade. Dentre essa biodiversidade, os besouros rola-bosta (Coleoptera: Scarabaeidae: Scarabaeinae) são um grupo de insetos que desempenham importantes funções ecológicas, tais como: ciclagem de nutrientes, dispersão de sementes e controle de parasitas. A fim de mitigar a falta de informações sobre a fauna de besouros rola-bosta do Pantanal brasileiro, realizamos uma pesquisa bibliográfica de praticamente toda a literatura publicada até novembro de 2020 sobre besouros rola-bosta amostrados no Pantanal. Além disso, acessamos os registros da maior coleção da espécie de rola-bosta do Pantanal brasileiro. Registramos 68 espécies de besouros rola-bosta de 30 gêneros. O gênero Canthon Holffmanseg 1847 é o mais diverso com 13 espécies registradas. Embora nosso conhecimento sobre a fauna de rola-bostas neste ecossistema ainda seja incipiente, nossos resultados demonstraram uma alta riqueza de besouros rola-bosta no Pantanal brasileiro. Além disso, nosso estudo fornece a primeira lista de espécies de besouros rola-bosta e uma chave de dicotomia ilustrada para identificar gêneros e algumas espécies encontrados no Pantanal brasileiro. Assim, a utilização deste guia para identificação das espécies de besouros rola-bostas e uma lista de espécies podem ser ferramentas importantes para auxiliar pesquisadores e incentivar novos inventários sobre a fauna de besouros rola-bostas no Pantanal brasileiro.

ABSTRACT: Sjögren syndrome is the second most common chronic autoimmune disease, environmental and hereditary mechanisms causes an autoimmune epithelitis that affect the exocrine glandular tissue mainly, but also other organs; because this broad spectrum of clinical characteristics, the diagnostic and treatment become a challenge. Studies has shown that 0.1-0.6 % of the population is affected, with predominance of females over males (9:1). In Colombia there are few descriptive epidemiological studies and characterization of the affected population. Clinical and epidemiological characterization of Sjögren syndrome patients. A descriptive cross-sectional observational study was conducted, 409 clinical histories of patients with the syndrome at San Ignacio University Hospital from 2012 to 2019 were analized. The data collected were subjected to a descriptive statistic. The average age of diagnosis was 59 years, the ratio female: male 9:1 (91.7 % and 8.3 % respectively), the highest frequency of the syndrome was found in the 51 to 60 years old group (131) followed by the 61 to 70 years old group (114). The most common clinical manifestation was xerostomia (90 %), minor salivary gland biopsy was the most frequent test requested (65 %). The osseoarticular involvement was the most frecuent concomitant disease. Although the etiology of Sjögren syndrome is little known, its characterization, as well as the identification of the diagnostic and therapeutic means used, is of great help in understanding the disease; this information will allow the development of increasingly effective and specific treatments. More studies are required, in different locations, which will highlight the differences between populations.

RESUMEN: El síndrome de Sjögren es la segunda enfermedad autoinmune crónica más prevalente; factores hereditarios y medioambientales interactúan provocando una “epitelitis autoinmune” que daña el tejido glandular exocrino principalmente, pero también a otros órganos; debido a esta heterogeneidad clínica, el diagnóstico y tratamiento constituyen un desafío. Estudios demuestran que afecta al 0,1-0,6 % de la población, con predilección por el sexo femenino (9:1). En Colombia existen pocos estudios epidemiológicos descriptivos y de caracterización en este síndrome. Caracterizar los parámetros clínicos y epidemiológicos de pacientes con síndrome de Sjögren. Se realizó un estudio observacional descriptivo de corte transversal, se revisaron historias clínicas de 409 pacientes con el síndrome que asistieron al Hospital Universitario San Ignacio entre 2012 y 2019. Los datos se analizaron usando estadística descriptiva. La edad promedio de diagnóstico fue 59 años, la relación mujer: hombre 9:1, (91,7 % y 8,3 % respectivamente). Hubo mayor prevalencia en pacientes de 51 a 60 años (131) seguido por los de 61-70 años (114). La manifestación clínica más común fue la xerostomía (90 %); la biopsia de glándula salival menor fue el examen complementario más solicitado (65 %). El compromiso óseo-articular, fue la enfermedad concomitante más asociada. La etiología de la enfermedad es poco conocida, sin embargo, su caracterización, así como la identificación de medios diagnósticos y terapéuticos ayuda en la comprensión de la clínica; dicha información permitirá el desarrollo de tratamientos cada vez más efectivos y específicos.

Abstract Background: Loud sound has a negative impact on the health of the neonate in the short and long term. Its reduction is a problem in the newborn intensive care unit (NICU). Objective: To determine the decibel levels inside and outside the incubator before and after speaking in the NICU of a tertiary care hospital. Material and methods: An experimental, analytical, prospective, cross-sectional study was carried out, accepted by the ethics committee. Decibels were measured before and after speaking inside and outside the incubator, and decibel levels were compared between shifts. Results: When comparing the average decibels inside the incubator before speaking, we found an average of 60 ± 3.8 and after speaking 65 ± 4 being statistically significant (< 0.001). The total average of decibels outside the incubator before speaking was 64.1 ± 3.7 and after speaking 69.1 ± 3.9 being statistically significant (< 0.001). Conclusions: After talking and comparing the decibels inside vs. outside, we found that outside the incubator is 4 decibels higher than inside (p < 0.001). When comparing the shifts, the evening shift was the noisiest and the night shift the least.

Abstract: Introduction: teratomas are the most common extragonadal germ cell neoplasm in neonates, but they can have different locations. We describe the diagnostic-therapeutic process of three newborns with this type of tumor. Cases presentation: these are three neonates in whom, before birth, a tumor was detected by echocardiography in different locations: orbit, oropharynx, and sacrococcygeal. All three underwent surgical resection in the perinatal stage. By histopathology, the report was a mature teratoma. Alpha-fetoprotein and human chorionic gonadotropin levels confirmed the diagnosis. At the age of six months, the postoperative course has been satisfactory. Conclusions: identification of teratomas during gestation is important for management planning at birth. Complete surgical resection is the treatment of choice, and serum levels of tumor markers should be part of long-term surveillance.

Resumen: Introducción: los teratomas constituyen la neoplasia germinal extragonadal más común en neonatos, pero pueden tener diferentes localizaciones. Presentamos tres recién nacidos con este tipo de tumores, a fin de dar a conocer el proceso diagnóstico-terapéutico. Presentación de los casos: se trata de tres RN en quienes, antes del nacimiento, se detectó la presencia de una tumoración por ecocardiografía en localizaciones diferentes: órbita, orofaringe y sacrococcígeo. En los tres se realizó resección quirúrgica en la etapa perinatal; por histopatología el reporte fue de teratoma maduro. Los niveles de alfafetoproteína y de la gonadotropina coriónica humana confirmaron el diagnóstico. A la edad de seis meses, la evolución postoperatoria ha sido satisfactoria. Conclusiones: la identificación de teratomas durante la gestación es importante para la planeación del manejo al nacimiento. La resección completa es el tratamiento de elección, y los niveles séricos de marcadores tumorales deben formar parte de la vigilancia a largo plazo.

Objective: To describe the methodological and operational aspects of the Cancer Surveillance Project and its associated factors: population-based and hospital-based registry (VIGICAN), in Mato Grosso (MT). Methods: VIGICAN was divided into two projects: an extension one, which updated the data from the Population-Based Cancer Registry (RCBP) of MT in the period 2008 to 2016; and one of research, which collected primary data, through individual interviews and analysis of medical records of people with a diagnosis of cancer, aged 18 years or over, treated at reference hospitals for oncology. To analyze the factors associated with cancer, the following variables were collected: socioeconomic and demographic, social support, status and health behavior, and environmental exposure. Results: In the períod from 2008 to 2016, approximately one hundred thousand cases of cancer (incident and prevalent) were reported in the RCBP Cuiabá and Interior. After validation procedures, fifty thousand incident cases were chosen. The survey interviewed 1,012 patients, 38.2% living in the municipalities of Cuiabá and Várzea Grande, 60.4% in the interior of the state and 1.4% in other states. Preliminary data revealed that the majority were female (55.0%) and younger than 60 years (54.3%). Among those interviewed, 7.2% reported smoking tobacco, 15.5% consumed alcoholic beverages (15.5%) and 32.7% lived close to crops. Conclusion: The development of these projects allowed the integration of education with health services and will enable the recognition of specificities and different exposure scenarios and factors associated with cancer in the Mato Grosso territory.

RESUMEN: Los viveros forestales que producen seedlings de especies nativas deben poner a disposición una alta diversidad forestal para satisfacer las demandas de los proyectos de recuperación. De esta forma, comprender el comportamiento de las diferentes especies y mejorar la tecnología de producción califica el manejo y reduce las pérdidas. Por lo tanto, se estudió el efecto de la adición de polímero hidroretenedor al sustrato sobre el desempeño de tres especies nativas cultivadas en condiciones de vivero. El diseño experimental fue completamente al azar con un esquema factorial. Se investigaron rasgos de supervivencia, morfológicos y fisiológicos en plántulas. En general, se observó que las especies estudiadas resultaron aptas para la técnica de trasplante con alta supervivencia a pesar de la influencia negativa del hidrogel sobre esta variable en las plántulas. Por otro lado, el uso de polímero hidroretenedor mejoró el crecimiento en altura, diámetro del tallo y la calidad de estas plántulas, demostrando ser una estrategia viable en la producción de seedlings nativas en un vivero.

SUMMARY: Forest nurseries that produce native species seedlings need to make heigh forestry diversity available to supply the demands of forest ecosystem recovery projects. In this way, understanding the behavior of different species and improving production technology improve management and reduce losses. We here studied the effect of the water-retaining polymer addition to the substrate on the performance of three native species grown under nursery conditions. The experimental design was completely randomized with a factorial scheme. Survival, morphological and physiological attributes of seedlings were investigated. In general, it was observed that studied species proved to be suitable for the subculturing technique, with high survival despite of hydrogel negative influence on this variable in seedlings. On the other hand, the use of water-retaining polymer improved growth in height, stem diameter and seedlings quality, demonstrating to be a viable strategy in native seedlings production in a nursery.

Resumen El agente causal de la enfermedad por coronavirus (COVID-19), asociado a síndrome respiratorio agudo grave (SARS-CoV-2), genera un espectro de síntomas que afectan fundamentalmente el sistema respiratorio, el sistema nervioso central (SNC), la regulación hemostásica y el sistema inmune. La parálisis bilateral de cuerdas vocales (PBCV) es una entidad cuya incidencia en infectados se desconoce, bien porque no se presentan durante el tiempo suficiente o por la dificultad de establecer una causalidad directa con el virus. La infección vírica, como causa de PBCV, está descrita en la literatura y se sospecha que una parte de los casos idiopáticos corresponden a infecciones víricas no diagnosticadas. Aunque los mecanismos neurotrópicos no están completamente aclarados para el SARS-CoV-2, existen indicios sólidos para asegurar su potencial neuroinvasivo. Las causas traumáticas, neoplásicas y neurológicas son las etiologías más comunes de PBCV, sin que se pueda descartar el origen vírico. Es plausible una causalidad entre el COVID-19 y la PBCV, que requerirá mayores estudios a corto y largo plazo. Presentamos una serie de casos que sostienen y discuten la hipótesis en consideración.

Abstract The agent that causes the coronavirus disease (COVID-19), associated with the severe acute respiratory syndrome (SARS-CoV-2), produces a spectrum of symptoms that mainly affect the respiratory system, the central nervous system (CNS), the regulation of hemostasis and the immune system. Bilateral vocal fold paralysis (BVFP) is a condition of unknown incidence among infected patients, either because it is short-lived or because of the difficulty in establishing a direct cause to the virus. Viral infection has been described in the literature as a cause of BVFP and there is the suspicion that a proportion of the idiopathic cases are due to undiagnosed viral infections. Although the neurotropic mechanisms for SARS-CoV-2 remain unclear, there is strong evidence to ensure its neuroinvasive potential. The most frequent etiologies of BVFP are trauma, neoplasm, and neurological, but a viral origin should not be ruled out. Causality between COVID-19 and BVFP is plausible and will require further study in the short and long term. We present a case series that support and discuss the hypothesis under consideration.

RESUMEN La curcumina contrarresta diversas patologías como el cáncer o enfermedades neuro-degenerativas. Sin embargo, su solubilidad es baja en soluciones acuosas limitando su aplicabilidad. Esta investigación elaboró una nanoemulsión estable de aceite en agua (O/W) a base de oleorresina deCúrcuma longa(ORC) para ser aplicada a bebida acuosa como una posible alternativa al uso de colorantes artificiales como la tartrazina. Se formularon y prepararon dos tipos de nanoemulsión: Oleorresina (EORC) y curcumina comercial 75 % (ECC). Estas se caracterizaron mediante el porcentaje de retención de curcumina (CR), contenido de fenoles totales (TPC); estabilidad física y tamaño de partícula (TP) por microscopía electrónica de transmisión (TEM). Se obtuvieron nanoemulsiones estables con TP de 10,201 nm y 13,847 para EORC y ECC respectivamente. EL CR hallado fue de 67,13 % (EORC) y 81,991 % (ECC); y, el contenido de fenoles para EORC fue de 35,466 y 36,128 mg EAGL/L para ECC. Igualmente, se obtuvieron bebidas acuosas a base de EORC con un CR de 80, 014 %. La bebida con EORC presentó mayor turbidez en comparación a la ECC y la tartrazina (control). Se obtuvieron nanoemulsiones y bebidas estables con aspectos diferenciables como color, turbidez, tamaño de partícula, separación de fases/tiempo. La EORC presentó mayor CR, por lo tanto, puede ser una alternativa potencial como colorante y antioxidante en bebidas acuosas.

ABSTRACT Curcumin counteracts over different pathologies like cancer or neurodegenerative diseases. However, its solubility is low in aqueous solutions therefore limiting its applicability. This study worked on obtaining an oil-in-water (O/W) stable oleoresin-based emulsion of Curcuma longa (ORC) to be applied into an aqueous beverage as an alternative to artificial colorants such as tartrazine. Two types of nanoemulsion were formulated and prepared: Oleoresin (EORC), and commercial curcumin 75 % (ECC). They were differentiated by percentage curcumin retention (CR), total phenol content (TPC); physical stability, and particle size (TP) under a Transmission Electron Microscopy (TEM). Two stable nanoemulsions were obtained with a TP of 10,201nm (EORC), and 13,847 nm for ECC. CR observed for EORC was 67,136 % and 8,991 % for ECC. Total Phenol content of 35,466 and 36,128 mg EAG/L respectively. Same way, aqueous beverages with EORC were processed and showed a CR of 80,014 %. EORC beverage presented higher turbidity compared to ECC and tartrazine (as control). Emulsions and beverages revealed settle aspects like color, turbidity; particles size or phase/time division. EORC exhibited greater CR which could be a possible alternative as colorant and antioxidant in aqueous beverages

Abstract This study aimed to evaluate the effect of synchronization with prostaglandin F2α in Baixadeiro mares during the rainy and dry seasons. Fourteen mares were synchronized by administering two doses of 1 mL prostaglandin PGF 2α and monitored by rectal palpation and ultrasound for the assessment of follicular development and uterine echotexture. Of this total, nine mares allowed the collection of blood, in which the blood was collected by venipuncture of the jugular vein to determine progesterone (P4) by ELISA. Mares showed no differences (P > 0.05) in weight, body score condition (BSC), tone, uterine edema, frequency of ovulation, synchronization interval, estrus, and the total number of follicles between periods. However, there was a difference in large increased follicle diameter (P < 0.05) during the dry season. The average concentrations of P4 in mares differed (P < 0.05) between the pre- and post-ovulatory phases for both seasons and after ovulation, with higher concentrations in the rainy season. Furthermore, statistical differences in daily light (P < 0.05) were observed between the dry and rainy periods. Thus, we conclude that mares from the genetic grouping Baixadeiro showed no reproductive seasonality, though there was a difference in luminosity between the rainy and dry seasons. The treatment with two doses of PGF 2α was effective in synchronizing the mares, promoting the return of estrus in the dry and rainy periods. The mares remaining cyclically active throughout the year provided there were appropriate forage availability and quality levels to allow for normal values of body weight and condition.

RESUMO O conhecimento das transformações de fase e o papel de diferentes parâmetros no desempenho de sistemas ligados a fosfato são de extrema importância para o campo refratário. Os efeitos do agente de endurecimento, da concentração de ácido fosfórico e dos aditivos no tempo de endurecimento, resistência ao impacto a frio, módulo de ruptura a quente, resistência à abrasão e resistência ao choque térmico dos sistemas refratários quimicamente ligados ao fosfato foram avaliados. O tempo de endurecimento foi menor para misturas contendo cimento (CaO) e uma menor concentração de ácido. Misturas com maior concentração de ácido apresentaram melhor resistência mecânica, à abrasão e ao choque térmico. Apesar de aumentar a resistência mecânica a frio e a abrasão dos materiais, o Budit 6H impactou negativamente as propriedades quentes. Para o aditivo Fabutit761, não houve formação de fase líquida em temperaturas intermediárias e esse aditivo aumentou a resistência mecânica a frio, mas também impactou negativamente a resistência mecânica a quente. As composições contendo cimento como agente endurecedor, ácido fosfórico a 40° Be e aditivo Fabutit761 como fonte extra de fosfato apresentaram um melhor conjunto de propriedades.

ABSTRACT The knowledge of the phase transformations and the role of different parameters in the performance of phosphate-bonded systems are of utmost importance for the refractory field. The effect of the setting agent, phosphoric acid concentration and additives on the setting time, cold crush strength, hot modulus of rupture, abrasion resistance, and thermal shock resistance of the phosphate chemically bonded refractory systems was evaluated. The setting time was shorter for mixtures containing cement (CaO) and a lower acid concentration. Mixtures with a higher acid concentration presented better mechanical, abrasion and thermal shock resistance. In spite of increasing the cold mechanical resistance and abrasion of the materials, the Budit 6H negatively impacted the hot properties. For Fabutit761, there was no liquid phase formation at intermediate temperatures and this additive increased the cold mechanical strength, but it also negatively impacted the hot mechanical strength. Compositions containing cement as a setting agent, 40°Be phosphoric acid and Fabutit761 additive as an extra source of phosphate presented a better set of properties.

To analyze the factors associated with cancer, the following variables were collected: socioeconomic and demographic, social support, health status and behavior, and environmental exposure. Results: In the 2008-2016 period, approximately one hundred thousand cases of cancer (incident and prevalent) were reported in the PBCR Cuiabá and PBCR Interior. After validation procedures, 50 thousand incident cases were elected. The survey interviewed 1,012 patients, 38.2% living in the municipalities of Cuiabá and Várzea Grande, 60.4% in small cities of the state, and 1.4% in other states. Preliminary data showed that the majority were women (55.0%) and younger than 60 years of age (54.3%). Among the interviewees, 7.2% reported smoking tobacco, 15.5% consumed alcoholic beverages (15.5%), and 32.7% lived nearby crops. Conclusion: The development of these projects allowed the integration of education with health services and will enable the recognition of specificities and different exposure scenarios and factors associated with cancer in the Mato Grosso territory.

ABSTRACT Objective: Analyze the temporal trend and spatial distribution of the incidence rate of dengue cases in Paraná and its regions between 2012 to 2021 and investigate associated sociodemographic and environmental variables. Methods: Ecological study with temporal and spatial analysis of the dengue incidence rate reported in the Disease and Notification Information System (SINAN) in the period 2012 to 2021 and investigation of sociodemographic and environmental variables. To identify differences between municipal incidence rates the Mann-Whitney and Kruskal-Wallis test followed by Dunn’s test for multiple comparisons were used. Prais-Winsten regression was used for temporal trend analysis and for spatial analysis the univariate and bivariate Local Moran analysis were applied. Results: 548,683 cases of dengue were confirmed in the period, the highest state incidence rate was observed in 2020, with 15 health regions presenting more than 500 cases/100,000 inhabitants. Higher incidences were observed among women, age group of 20-59 years and white color/race. Despite annual variations, a stationary trend was observed for incidence rates according to sex, age group, color/race and macro-region. More than half of the municipalities in Paraná formed spatial clusters (Moran’s I=0.679), where 73 (18.3%) municipalities with high incidence rate formed clusters. High-High clusters of dengue incidence rate with urbanization and High-Low clusters of incidence rate with vegetation cover were observed. Conclusion: Sociodemographic and environmental determinants were related to the high incidence rates of dengue and heterogeneous spatial distribution in the state of Paraná, indicating the need to strengthen health surveillance actions.

Resultados: Foram confirmados 548.683 casos de dengue no período, apresentando a maior taxa de incidência estadual em 2020, com 15 regionais de saúde registrando mais de 500 casos/100 mil habitantes. Maiores incidências ficaram entre mulheres, faixa etária de 20-59 anos e cor/raça branca. Apesar de variações anuais, observou-se tendência estacionária para incidência segundo sexo, faixa etária, cor e macrorregião. Mais da metade dos municípios paranaenses formou aglomerados espaciais (Moran’s 1=0,679) — 73 (18,3%) municípios com alta taxa de incidência formaram agrupamentos. Foram identificados agrupamentos da taxa de incidência da dengue com o grau de urbanização (alto-alto) e com o percentual de cobertura vegetal natural (alto-baixa). Conclusão: Determinantes sociodemográficos e ambientais relacionaram-se com as altas taxas de incidência da dengue e com a distribuição espacial heterogênea no estado do Paraná, indicando a necessidade do fortalecimento das ações de vigilância em saúde.

RESUMO Objetivo: Analisar a tendência temporal e a distribuição espacial da taxa de incidência de casos de dengue no Paraná e suas regiões entre 2012 e 2021 e investigar variáveis sociodemográficas e ambientais associadas. Métodos: Estudo ecológico com análises temporais e espaciais da taxa de incidência da dengue registrada no Sistema de Informação de Agravos de Notificação, de 2012 e 2021, e investigação de variáveis sociodemográficas e ambientais. Para analisar as taxas de incidência municipais foram utilizados os testes de Mann-Whitney e Kruskal-Wallis, seguidos do teste de Dunn para múltiplas comparações. Utilizou-se para análise da tendência temporal a regressão de Prais-Winsten, e para a análise espacial, o índice de Moran Local univariado e bivariado.

ABSTRACT Objective: Analyze the temporal trend and spatial distribution of the incidence rate of dengue cases in Paraná and its regions between 2012 to 2021 and investigate associated sociodemographic and environmental variables. Methods: Ecological study with temporal and spatial analysis of the dengue incidence rate reported in the Disease and Notification Information System (SINAN) in the period 2012 to 2021 and investigation of sociodemographic and environmental variables. To identify differences between municipal incidence rates the Mann-Whitney and Kruskal-Wallis test followed by Dunn’s test for multiple comparisons were used. Prais-Winsten regression was used for temporal trend analysis and for spatial analysis the univariate and bivariate Local Moran analysis were applied. Results: 548,683 cases of dengue were confirmed in the period, the highest state incidence rate was observed in 2020, with 15 health regions presenting more than 500 cases/100,000 inhabitants. Higher incidences were observed among women, age group of 20-59 years and white color/race. Despite annual variations, a stationary trend was observed for incidence rates according to sex, age group, color/race and macro-region. More than half of the municipalities in Paraná formed spatial clusters (Moran’s I=0.679), where 73 (18.3%) municipalities with high incidence rate formed clusters. High-High clusters of dengue incidence rate with urbanization and High-Low clusters of incidence rate with vegetation cover were observed. Conclusion: Sociodemographic and environmental determinants were related to the high incidence rates of dengue and heterogeneous spatial distribution in the state of Paraná, indicating the need to strengthen health surveillance actions.
