Abstract Objective: To verify the students’ perception about diabetes in public schools. Methods: Descriptive cross-sectional study, with students’ interview to access their diabetes knowledge (signs and symptoms, food, and diabetes self-care at school). Content analysis was used for the open question, expressed by number of occurrences, and frequencies, means and standard deviations for the other results. Results: 302 students, with 9,1±1,5 years and 54% female. For “what is diabetes” there were 91 occurrences associated with negative consequences. For 95.4% of interviewees, people with diabetes cannot eat sweets, and for 32.8% diabetes is transmitted from person to person. Only 34.8% stated that the classmate with diabetes can participate in physical/recreational activities; and 32.1% replied that he/she could not have a snack with the others. Only 29.2% of the interviewees recognized that the classmate with diabetes would need to have something with sugar to eat/drink in case he/she feel bad. Conclusions: These results reinforce the need for action of diabetes education to improve students' knowledge and perception about diabetes in the school, as well as better management for students with this condition at that environment.

ABSTRACT Numerous tests employed to predict cardiac and functional status are expensive and not widely accessible for a considerable number of patients, particularly those diagnosed with Chagas disease (CD) residing in remote and endemic regions. To date, there is no knowledge of studies that have validated instruments that address functionality in an expanded way, including the biopsychosocial factors in patients with CD. This study aims to evaluate the psychometric properties of the World Health Organization Disability Assessment Schedule (WHODAS 2.0), in its 12-item shortened version (WHODAS-12) when applied to patients with CD. This is a cross-sectional study of a prospective cohort that follows individuals with CD (SaMi-Trop). Data collection took place between October 2019 and March 2020. In the interviews, sociodemographic information, life habits, clinical information, and indicators of disability measured by WHODAS-12 were collected. Descriptive analysis, internal consistency and construct validity of the instrument were performed. A total of 628 patients with CD were interviewed, most were women (69.5%), their mean age was of 57 years, and most declared an average self-perception of health (43.4%). The 12 items of WHODAS-12 were distributed into three factors, which together account for 61% of the variance. The Kaiser–Meyer–Olkin (KMO) index was 0.90, indicating adequacy of the sample for factor analysis. The internal consistency of the global scale showed alpha = 0.87. The percentage of incapacity was 16.05%, indicating mild incapacity for the evaluated patients. WHODAS-12 is a valid and reliable measure to assess the disability of the Brazilian population with CD.

ABSTRACT Chagas disease (CD) is a neglected disease caused by the protozoan Trypanosoma cruzi. It has high morbidity and mortality rates and mainly affects socially vulnerable populations. This is a cross-sectional study, with retrospective and prospective data collection. Using questionnaires applied to environmental surveillance coordinators, we characterized the status of CD surveillance activities in municipalities endemic for the disease in Northern Minas Gerais State (MG) and Jequitinhonha Valley (Vale do Jequitinhonha). Moreover, we spatialized the vulnerability index for chronic CD in the study area. The population consisted of 22 environmental surveillance coordinators, active in 2020, from Northern MG and Jequitinhonha Valley, 21 municipalities included in the SaMi-Trop research project, and Montes Claros municipality. After applying the questionnaires to the coordinators, a descriptive analysis of the variables was performed. To characterize the active municipalities, the explanatory variables collected in the questionnaire were compared with the dichotomous variable. Bivariate descriptive analysis was performed. Finally, geoprocessing techniques were used to spatialize the data and prepare maps. Regarding the team of endemic combat agents (ECA), 90.9% reported the lack of a specific team for CD vector control actions. Of the 22 municipalities participating in this study, nine were active (41.1%). Only 25% (n=2) of active municipalities (9% of the municipalities studied) met the target of visiting 50% of households per year. Finally, 81.1% of the coordinators stated that in their municipality, they developed actions linked to primary health care (PHC). The implementation of CD surveillance activities weakened in the endemic region. Few municipalities have a surveillance team, with low regularity of active surveillance and noncompliance with the program’s goal. The results suggest insufficient recording of activities in the information system, considering that there are municipalities that report performing the activities, but no production record was observed in the system.

ABSTRACT Background: Chagas disease (ChD) is a neglected tropical disease that is caused by the protozoan parasite Trypanosoma cruzi and can negatively impact quality of life (QoL). This study aimed to assess and compare QoL between individuals with and without ChD. Methods: This cross-sectional study was performed within a concurrent cohort study (REDS). The participants were derived from two blood donation centers: São Paulo capital and Montes Claros, Minas Gerais, Brazil. Participants with ChD were identified in blood donations by serological diagnosis between 2008 and 2010, and those without ChD were donors with negative serology identified during the same period. QoL was assessed using the World Health Organization Quality of Life-BREF questionnaire. Logistic regression was used to compare sociodemographic and clinical characteristics between the groups, and mean, standard deviation, and beta regression were used to compare QoL. Results: In total, 611 individuals participated in the study (328 with ChD and 283 without ChD). Participants with ChD had lower QoL in the physical (p=0.02) and psychological (p<0.01) domains than did individuals without CD. Conclusions: Individuals with ChD had worse QoL perceptions. These results provide a comprehensive understanding of the impact of ChD on individuals' QoL, while also highlighting potential opportunities for improving the care and treatment of those affected.

Resumo A composição florística dos campos rupestres compreende um mosaico de espécies com adaptações distintas, exibindo alta diversidade e endemismo. Entretanto, as plantas dos campos rupestres possuem dependência às condições específicas do local e sua reprodução quase sempre é limitada, tornando difícil a regeneração natural após perturbações. O banco de sementes do solo representa um fator potencial para a regeneração deste ambiente. Objetivou-se avaliar o banco de sementes do solo de diferentes profundidades de uma área de campo rupestre, coletado em duas estações climáticas e submetido a duas condições de luminosidade. Foram coletadas amostras compostas de serapilheira e de solo (0-5 cm) em 13 parcelas de 100 m2, em uma área de campo rupestre na Serra do Cipó (Minas Gerais), nas estações seca e chuvosa. As amostras foram submetidas às condições de luminosidade pleno sol e sombreamento. No total, emergiram 185 plântulas pertencentes a 31 espécies e a nove famílias botânicas. As famílias com maior riqueza foram Cyperaceae, Poaceae e Asteraceae. Houve variação de riqueza, abundância e composição florística entre as profundidades do solo, mas não foi observada variação em relação à estacionalidade e às condições de luminosidade. As amostras de solo apresentaram valores superiores dos parâmetros avaliados em relação àquelas da serapilheira, mostrando que o banco de sementes é mais representativo no solo. Esses resultados demonstram que existe potencial de regeneração do campo rupestre por meio do banco de sementes do solo.

Abstract The floristic composition of the rupestrian grasslands comprises a mosaic of species with different adaptations exhibiting high diversity and endemism. However, the plant species from rupestrian grasslands are dependent on site-specific conditions and their reproduction is almost always limited, making natural regeneration after disturbances difficult. The soil seed bank represents a potential factor for the regeneration of this environment. The objective was to evaluate the soil seed bank of different depths of a rupestrian grassland area, collected in two climatic seasons and submitted to different light conditions. The samples composed of litter and soil (0-5 cm) were collected in 13 plots of 100 m2, in a rupestrian grassland area in Serra do Cipó (Minas Gerais state), in dry and rainy seasons. The samples were subjected to full sun and shading conditions. In total, 185 seedlings of 31 species and nine botanical families emerged. The richest families were Cyperaceae, Poaceae and Asteraceae. There was variation in richness, abundance and floristic composition among the soil strata, but no variation was observed in relation to seasonality and light conditions. The soil samples presented higher values of the evaluated parameters in relation to those ones of litter, showing that the seed bank is more representative in the soil stratum. These results demonstrate that there is potential for rupestrian grassland regenerations through the seed bank, especially the soil stratum.

ABSTRACT The SaMi-Trop project is a cohort study conducted in 21 municipalities of endemic areas of Chagas disease, including 1,959 patients with chronic Chagas cardiomyopathy. In this article we updated the results of the project, adding information from the second cohort visit. Trypanosoma cruzi-seropositive patients were enrolled from the primary care Telehealth service in Minas Gerais State, Brazil. The eligibility criterium for the second visit was the participation in the baseline evaluation. Of 1,959 participants at the baseline assessment, 1,585 (79.9%) returned after two years for the second evaluation. The mortality rate was 6.7%, but varied from 0.9% to 18.2% when it was stratified by certain clinical characteristics. A lower age-adjusted NT-Pro-BNP level (less than 300) and a prior benznidazole treatment were associated with lower mortality. There was an improvement in most quality of life domain scores. Participants have also reported fewer signs and symptoms and greater use of medication. The second follow-up visit will be complete in Oct 2021.

Abstract Many factors can influence the structures and distributions of plant communities. Plant diversity of swamp forests reflect responses to water stress conditions. We evaluated the floristic diversity, structure, and composition of the regenerating shrub-tree species of six swamp forests in veredas ecosystems (northern Minas Gerais, Brazil), and the floristic similarities between them. All individuals ≥ 1 cm in diameter at ground level and < 3 cm in diameter at breast height were sampled in one hundred 25 m2 plots in each area. A total of 5442 individuals were recorded, distributed among 134 species, 85 genera, and 47 botanical families, with a diversity (Shannon) of 3.38 and equability (Pielou) of 0.69. Beta diversity was high, while similarities between the areas were low, with only two species common to all six sites. The forests showed different compositions, diversities, and natural regeneration structures, reflecting their ecotone nature and past anthropic impacts.

RESUMO A ferrugem asiática da soja (FAS), causada pelo fungo Phakopsora pachyrhizi, é uma das doenças mais severas na cultura. Dentre as estratégias para seu manejo propõe-se a utilização de genótipos com resistência horizontal ou parcial, ainda restritos no mercado, mas promissores pela durabilidade da resistência. O objetivo deste trabalho foi avaliar a resistência de diferentes genótipos de soja à ferrugem asiática para futura utilização em programas de melhoramento. Na safra 2015/2016, foram avaliados 11 genótipos de soja provenientes do LAGER-UFU e a cultivar Desafio 8473 (padrão de suscetibilidade) frente à infecção artificial e natural de P. pachyrhizi no campo. Com os dados de severidade da FAS, calculou-se a área abaixo da curva de progresso da doença (AACPD). O percentual de área foliar afetada e os valores da AACPD dos genótipos avaliados oscilaram de 1,56 a 80,75 e de 380,62 a 975,62, respectivamente. Os genótipos L-210, L-166, L-268, L-203, L-279, L-224, L-216 e L-218 apresentam menores valores de AACPD, indicando resistência parcial, enquanto os genótipos L-144, L-104, L-266 e a cv. Desafio 8473 apresentaram maiores valores de AACPD, portanto, com menor resistência parcial ou suscetíveis. Ainda assim, os genótipos L-144, L-104 e L-266 apresentaram coeficientes de progresso da severidade da doença de 1,8 a 2,0 vezes menores comparativamente à cv. Desafio 8473. Conclui-se que os genótipos do Programa de Melhoramento Genético da UFU (LAGER-UFU), apresentam potencial de utilização no desenvolvimento de cultivares de soja resistentes à P. pachyrhizi.

ABSTRACT Asian soybean rust (ASR), caused by the fungus Phakopsora pachyrhizi, is one of the most severe diseases that affect the crop. Among management strategies is the use of genotypes with horizontal or partial resistance, which are still restricted in the market but promising due to their resistance durability. The objective of this study was to evaluate the resistance of different genotypes to Asian soybean rust for future use in breeding programs. In the 2015/2016 crop season, 11 soybean genotypes from LAGER-UFU and cv. Desafio8473 (susceptibility pattern) were evaluated for artificial and natural infection by P. pachyrhizi in the field. ASR severity data were used to calculate the area under the disease progress curve (AUDPC). The percentage of affected leaf area and the AUDPC values of the evaluated genotypes ranged from 1.56 to 80.75% and from 380.62 to 975.62, respectively. The genotypes L-210, L-166, L-268, L-203, L-279, L-224, L-216 and L-218 have lower AUDPC values, indicating partial resistance, while the genotypes L-144, L-104, L-266 and cv. Desafio 8473 showed higher AUDPC values and therefore lower partial resistance or susceptibility. Even so, the genotypes L-144, L-104 and L-266 showed coefficients of disease severity progress 1.8 to 2.0-fold lower than those of cv. Desafio 8473. In conclusion, the genotypes from UFU Breeding Program (LAGER-UFU) showed potential to be used in the development of soybean cultivars resistant to P. pachyrhizi.

Abstract INTRODUCTION: Female sex workers (FSWs) are considered a bridge for transmission of pathogens from high-risk to general populations. We assessed the epidemiological status of syphilis in FSWs along the Pará highway system. METHODS: Two hundred and twenty-two FSWs were interviewed and samples were analyzed using rapid qualitative tests and real-time polymerase chain reaction. RESULTS: The prevalence of syphilis was high (36.94%). The high rate of prostitution, use of illicit drugs, and search for financial resources increased Treponema pallidum transmission through unprotected sex. CONCLUSIONS: Several characteristics of FSWs were identified, which reinforce the need for measures guaranteeing their health and protection.

Abstract INTRODUCTION: Herein, we assessed the seroprevalence and spatial distribution of Leishmania infantum in dogs in Garanhuns, Northeastern Brazil. METHODS: Sera samples (n = 242) were analyzed using an enzyme-linked immunosorbent assay (ELISA). The spatial distribution of dogs seropositive for anti-Leishmania infantum antibodies was evaluated using kernel density estimation. RESULTS: A total of 2.4% (6/242) of the animals were seropositive for anti-Leishmania infantum antibodies. The kernel map showed their distribution to be heterogeneous over the city, with a hotspot in the northeastern region. CONCLUSIONS: The reported data illustrate the circulation of parasites of the genus Leishmania in a canine population.

Abstract Background: Individuals with sickle cell anemia may suffer symptomatic or silent cerebral infarcts leading to neurocognitive complications. This study investigated the cognitive and intellectual performance of children and adolescents with sickle cell anemia. Methods: The socioeconomic status, clinical aspects and behavioral profile of 15 young individuals with sickle cell anemia were evaluated. The Wechsler Intelligence Scale for Children, the Developmental Neuropsychological Assessment Test, and the Child Behavior Checklist were applied. Results: Participants with a history of stroke had lower intelligence quotient (IQ) scores. Alterations were found in attention and executive functioning, language, verbal and visual memory, visuospatial processing and sensorimotor skills. These alterations were found both in the children and adolescents who had had a cerebral infarction and in those who apparently had not. In the majority of cases, there were learning difficulties, a history of repeating school years and a need for specialist educational support. The most common additional diagnoses in accordance with the Diagnostic and Statistical Manual of Mental Disorders IV were depressive disorder, anxiety disorder and somatic disorder, as well as conditions associated with physical and psychosocial repercussions of sickle cell anemia. Conclusion: As sickle cell anemia is considered a progressive cerebral vasculopathy, it is a potential risk factor for neurocognitive and psychosocial development. Therefore, periodic neuropsychological and behavioral evaluations of children and adolescents with sickle cell anemia may represent a useful measure to reduce long-term biopsychosocial repercussions.

Abstract: An integrative literature review was conducted to synthesize available publications regarding the potential use of serological tests in leprosy programs. We searched the databases Literatura Latino-Americana e do Caribe em Ciências da Saúde, Índice Bibliográfico Espanhol em Ciências da Saúde, Acervo da Biblioteca da Organização Pan-Americana da Saúde, Medical Literature Analysis and Retrieval System Online, Hanseníase, National Library of Medicine, Scopus, Ovid, Cinahl, and Web of Science for articles investigating the use of serological tests for antibodies against phenolic glycolipid-I (PGL-I), ML0405, ML2331, leprosy IDRI diagnostic-1 (LID-1), and natural disaccharide octyl-leprosy IDRI diagnostic-1 (NDO-LID). From an initial pool of 3.514 articles, 40 full-length articles fulfilled our inclusion criteria. Based on these papers, we concluded that these antibodies can be used to assist in diagnosing leprosy, detecting neuritis, monitoring therapeutic efficacy, and monitoring household contacts or at-risk populations in leprosy-endemic areas. Thus, available data suggest that serological tests could contribute substantially to leprosy management.

A pesquisa estimou prevalência e fatores associados ao risco cardiovascular elevado (RCE), a partir da obesidade abdominal, em uma amostra de 316 policiais militares (PMs) de uma cidade de grande porte do Nordeste do Brasil. Os preditores selecionados foram: sexo, idade, situação conjugal, graduação, função e tempo na polícia, nível de atividade física e tabagismo. Empregou-se a regressão logística de Poisson, com variância robusta, para avaliar a associação entre RCE e fatores sociodemográficos, comportamentais e relacionados ao trabalho policial. O RCE ocorreu em 32,3% dos PMs pesquisados. Na análise ajustada, sexo (RP: 2,39; IC95%: 1,20-4,77), tempo na polícia (RP: 1,74; IC95%: 1,17-2,58) e nível de atividade física (RP: 1,36; IC95%: 1,00-1,83) foram associados com o RCE entre os policiais, ajustados por graduação.

This research estimated the prevalence and factors associated with high cardiovascular risk (HCR), evaluating from abdominal obesity in a sample of 316 military policemen of a large city in Northeastern Brazil. Predictors: gender, age, marital status, graduation, function and time in the police, level of physical activity and smoking. We used the Poisson regression with robust variance to assess the association between HCR and sociodemographic, behavioral and work-related factors. The HCR occurred in 32.3% of subjects surveyed. In the adjusted analysis, gender (OR: 2.39, IC95%: 1.20-4.77), time in the police (OR: 1.74, IC95%: 1.17-2.58) and physical activity level (OR: 1.36, IC95%: 1.00-1.83) were associated with HCR among subjects, adjusted for graduation.

Este estudio estima la prevalencia y los factores asociados con alto riesgo cardiovascular (RCV) de la obesidad abdominal en una muestra de 316 policía militar de una gran ciudad en el noreste de Brasil. Los predictores: género, edad, estado civil, la graduación, la función y el tiempo en la policía, el nivel de actividad física y el tabaquismo. Se utilizó la regresión de Poisson con varianza robusta para evaluar la asociación entre RCV y los predictores socio demográficos, conductuales y relacionados con el trabajo policial. El RCV se produjo en el 32,3% de los sujetos. En el análisis ajustado, género (RP: 2.39; IC95%: 1,20-4.77), tiempo en policía (RP: 1.74; IC95%: 1,17-2.58) y el nivel de actividad física (RP: 1,36; IC95%: 1,00-1.83) se asociaron con RCV entre los sujetos, ajustado para la graduación.
