Abstract The study provides the first record of Eumops glaucinus in the Maranhão state, located in the northern region of Brazil. The collected specimen was a non-lactating adult female, with grayish pelage, broad ears, smooth face, a well-developed and squarish tragus, and elongated snout. The combined analysis of the morphological and molecular data (COI, Cyt b, and rRNA 16S genes) confirmed the occurrence of E. glaucinus in the state of Maranhão. This record extends the known species range area by 660 km easternward from the closest locality, Belém, Pará.

Abstract The bat genus Sturnira is widely distributed in the Neotropical region, from northwestern Mexico to northern Argentina, and four species occur in Brazil: Sturnira lilium, Sturnira giannae, Sturnira magna, and Sturnira tildae. The present study is the first to record Sturnira tildae in the state of Maranhão, Brazil, based on morphological and molecular diagnoses. The specimen was identified based on its cranial and morphometric traits. The diagnostic traits include discreetly bilobed inner upper incisors with a broad base, lower first and second molars with lingual cusps separated by shallow grooves, and forearm longer than 45 mm. The molecular sequences of Cytochrome C Oxidase Subunit 1 (COI) and 16S rRNA genes confirmed the morphological identification and thus the occurrence of Sturnira tildae in the Amazon biome of Maranhão. This record represents an eastward extension of the known distribution of the species in the Amazonia, to Cândido Mendes, Maranhão, within an area dominated by dense rainforest and influenced by tides.

Abstract INTRODUCTION We aimed to analyze trends in Schistosomiasis positivity, mortality, and hospitalization rates in Northeast Brazil. METHODS We conducted an ecological study using data from the Brazilian Schistosomiasis Control Program, and Hospital and Mortality Information Systems. A joinpoint regression model was used for temporal analysis. RESULTS The positivity(−4.7%;p<0.001) and hospitalization(−17.7%;p<0.001) rates declined globally, while the mortality remained stationary (−0.8%;p>0.05). However, the hospitalization in Alagoas(27.1%;p<0.001) and Pernambuco (35.1%;p<0.001), and the mortality in Bahia(2.9%;p<0.001) and Sergipe(4.1%;p<0.001), increased. CONCLUSIONS Schistosomiasis mansoni represents an important public health problem in Pernambuco, Alagoas, Sergipe, and Bahia.

Abstract Objective: to test the hypothesis that acute physical exercise would change the fatty acids in the serum of individuals with increased body weight. Method: sixty-six sedentary women with excess weight were included in the sample (BMI = 29.6 ± 4.2). They were aged 24.4 ± 3.6 years and were randomly divided into control and exercise groups. After 12 hours fasting, basal blood collection was performed. Twelve hours after the first collection, the exercise group was submitted to a physical exercise session with energy expenditure of 250 kcal. The volunteers underwent a second blood collection 24 hours after the first one and dosed the fatty acids: pelargonic, azelaic, elaidic and oleic. Results: physical exercise did not change the fatty acid profile response for both the intragroup analysis and intergroup analysis. Exercise group: pelargonic (before = 0.12 ± 0.06% vs after = 0.15 ± 0.14%, p = 0.507); azelaic (before = 20.3 ± 10.5% vs after = 27.7 ± 25.4%, p = 0.295); elaidic (before = 0.03 ± 0.01% vs after = 0.04 ± 0.01%, p = 0.328); oleic (before = 16.1 ± 7.4% vs after = 20.3 ± 14.6%, p = 0.236). Control group: pelargonic (before = 0.70 ± 0.45% vs after = 0.71 ± 0.51%, p = 0.776); azelaic (before = 62.1 ± 26% vs after = 57.1 ± 27%, p = 0.197); elaidic (before = 0.05 ± 0.02% mg/dl vs after = 0.05 ± 0.03%, p = 0.530); oleic (before = 26.8 ± 22.7% mg/dl vs after = 29.0 ± 22.4%, p = 0.525). Conclusion: in women with overweight, low intensity physical exercise is not capable of changing the medium-chain fatty acids in the first 12 hours.

Resumen Objetivo: probar la hipótesis de que ejercicio físico agudo cambiaría los ácidos grasos en el suero de las personas con mayor peso corporal. Método: se incluyeron en la muestra sesenta y seis mujeres sedentarias con exceso de peso (IMC = 29.6 ± 4.2). Tenían una edad de 24,4 ± 3,6 años y se dividieron aleatoriamente en grupos de control y ejercicio. Después de 12 horas de ayuno, se realizó la extracción de sangre basal. Doce horas después de la primera extracción, el grupo de ejercicio se sometió a una sesión de ejercicio físico con un gasto de energía de 250 kcal. Los voluntarios se sometieron a una segunda extracción de sangre 24 horas después de la primera con dosificación de los ácidos grasos: pelargónico, azelaico, elaídico y oleico. Resultados: el ejercicio físico no modificó la respuesta del perfil de ácidos grasos para el análisis intragrupo y el análisis intergrupo. Ejercicio grupo: pelargónico (antes = 0,12 ± 0,06% vs después = 0,15 ± 0,14%, p = 0,507); azelaico (antes = 20,3 ± 10,5% vs después = 27,7 ± 25,4%, p = 0,295); elaídico (antes = 0,03 ± 0,01% vs después = 0,04 ± 0,01%, p = 0,328); oleico (antes = 16,1 ± 7,4% vs después = 20,3 ± 14,6%, p = 0,236). Grupo de control: pelargónico (antes = 0,70 ± 0,45% vs después = 0,71 ± 0,51%, p = 0,776); azelaico (antes = 62,1 ± 26% vs después = 57,1 ± 27%, p = 0,197); elaídico (antes = 0,05 ± 0,02% mg/dl vs después = 0,05 ± 0,03%, p = 0,530); oleico (antes = 26.8 ± 22,7% mg/dl vs después = 29,0 ± 22,4%, p = 0,525). Conclusión: en mujeres con sobrepeso, el ejercicio físico de baja intensidad no produce ningún cambio en los ácidos grasos de cadena media en las primeras 12 horas.

RESUMO A elevação de 1% no HDL-C associa-se à redução de 3% nas taxas de mortalidade cardiovascular. Contudo, praticar exercícios a ponto de gerar alterações benéficas do HDL-C ainda é controverso. Portanto, o objetivo deste estudo foi avaliar se existe benefício do exercício físico sobre os níveis de HDL-C. Trata-se de uma revisão sistemática de metanálises, de artigos indexados ao PubMed/MEDLINE, SciELO e LILACS. Utilizaram-se os termos, Lipoproteins, Cholesterol, HDL, Exercise and Resistance Training. Critérios de inclusão: metanálises publicadas até 22 de janeiro de 2015, com o exercício como forma de intervenção e com desfecho no HDL-C. Critérios de exclusão: Não citação de efeitos de confusão, avaliação do HDL-C como desfecho secundário ou intervenção dietética. Com relação ao resultado do treinamento aeróbico, avaliamos oito estudos. Quatro foram significantes para aumento de HDL-C. Destes, a menor duração em semanas foi 21,8 ± 19,5 e a maior foi 35,3 ± 31,8; a menor frequência foi 3,5 ± 1,0 e a maior, 4,0 ± 1,1; a menor intensidade/%VO2máx foi 64,8% e a maior, 69,2 ± 10,1. Quatro estudos não foram significantes, sendo a menor duração em semanas 10,7 ± 3,2 e a maior, 23,19 ± 17,7; a menor frequência foi 3,7 ± 0,8 e a maior foi 4,75 ± 2,5; a menor intensidade/%VO2máx foi 64,2 ± 9,4 e a maior, 74,7 ± 11,8. Treinamento resistido: Nenhum dos três estudos foi significante. Treinamento combinado: Um único estudo apresentou aumento dos níveis de HDL-C (diferença média [IC 95%]: 0,08 (IC 95%, 0,05-0,12 mmol/l]). Concluímos que não é possível afirmar que o treinamento aeróbico, resistido ou combinado, proporcionam aumentos significantes nos níveis de HDL-C, o que limita sua prescrição como terapia eficiente para aumento de HDL-C.

ABSTRACT The 1% increase in HDL-C is associated with a 3% reduction in cardiovascular mortality rates. However, exercising to the point of generating beneficial changes in HDL-C is still controversial. Therefore, the objective of this study was to evaluate whether there is a benefit of physical exercise on HDL-C levels. This is a systematic review of meta-analyses in articles indexed to PubMed/MEDLINE, SciELO and LILACS. We used the terms Lipoproteins, Cholesterol, HDL, Exercise and Resistance Training. Inclusion criteria: Meta-analyses published until January 22, 2015, with exercise as an intervention and with HDL-C endpoint. Exclusion criteria: No citation of confounding effects, assessment of HDL-C as a secondary endpoint, or dietary intervention. Regarding the aerobic training results, we evaluated eight studies. Four were significant for increased HDL-C. Of these the shortest duration in weeks was 21.8±19.5 and the highest was 35.3±31.8; the lowest frequency was 3.5±1.0 and the highest 4.0±1.1; the lowest intensity/%VO 2max was 64.8% and the highest 69.2±10.1. Four studies were not significant, being the shortest duration in weeks: 10.7±3.2 and the highest 23.19±17.7; the lowest frequency was 3.7±0.8 and the highest was 4.75±2.5; the lowest intensity/%VO 2maxwas 64.2±9.4 and the highest 74.7 ± 11.8. Resistance training: None of the three studies was significant. Combined training: A single study showed an increase in HDL-C levels (mean difference [95% CI]: 0.08 [95% CI, 0.05 -0.12 mmol/L]).We concluded that it is not possible to state that aerobic training, resisted or combined, provides significant increases in HDL-C levels, which limits its prescription as an efficient therapy for HDL-C increase.

RESUMEN Un aumento de 1% en el HDL-C se asocia con una reducción del 3% en las tasas de mortalidad cardiovascular. Sin embargo, el ejercicio hasta el punto de generar cambios beneficiosos en el HDL-C sigue siendo controvertido. Por lo tanto, el objetivo de este estudio fue evaluar si existe un beneficio del ejercicio sobre los niveles de HDL-C. Se trata de una revisión sistemática de los metaanálisis de artículos indexados a PubMed/MEDLINE, SciELO y LILACS. Utilizamos los términos Lipoproteins, Cholesterol, HDL, Exercise and Resistance Training. Criterios de inclusión: metaanálisis publicados hasta el 22 de enero de 2015, con el ejercicio como una intervención y el resultado de HDL-C. Criterios de exclusión: No se mencionan los efectos de confusión, la evaluación de HDL-C como criterio secundario de valoración o intervención dietética. Como resultado del entrenamiento aeróbico, se evaluaron ocho estudios. Cuatro fueron significativos en relación al aumento de HDL-C. De estos, el tiempo más corto en semanas fue de 21,8 ± 19,5 y el más largo fue de 35,3 ± 31,8; la frecuencia más baja fue de 3,5 ± 1,0 y la más alta fue de 4,0 ± 1,1, la intensidad/%VO 2máx más baja fue 64,8% y la más alta fue 69,2 ± 10.1 Cuatro estudios no fueron significativos, siendo la menor duración en semanas de 10,7 ± 3,2, y la más grande de 23,19 ± 17,7; la frecuencia más baja fue de 3,7 ± 0,8 y la más alta fue 4,75 ± 2,5; la intensidad/%VO 2máxmás baja fue de 64,2 ± 9,4 y la más alta fue 74,7 ± 11.8. Entrenamiento de resistencia: Ninguno de los tres estudios fue significativo. Entrenamiento combinado: Un único estudio presentó un aumento de los niveles de HDL-C (diferencia promedio [IC 95%]: 0,08 [IC 95%, 0,05-0,12 mmol/l]). Llegamos a la conclusión de que no es posible decir que el entrenamiento aeróbico, de resistencia o combinado, proporciona un aumento significativo de los niveles de HDL-C, lo que limita su prescripción como terapia efectiva para aumentar el HDL-C.

RESUMO Neste estudo prospectivo foi avaliada a influência do polimorfismo -351A/G XbaI do gene do receptor de estrogênio alfa (ESR-1) sobre o desempenho cognitivo global em idosos muito idosos (≥ 75 anos) saudáveis durante um ano. Métodos Os indivíduos foram divididos em dois grupos de acordo com a presença ou ausência de declínio cognitivo. Dados cognitivos foram relacionados à informação genética. Resultados O genótipo XbaI -351 AA foi mais comum entre indivíduos que apresentaram declínio cognitivo, enquanto carreadores do alelo -351G demonstraram estabilidade ou melhora cognitiva. Conclusão Estes resultados sugerem que ESR-1 poderia estar associado ao declínio cognitivo em curto prazo em idosos saudáveis, possivelmente por meio de propriedades neuroprotetoras do estrogênio, mesmo em cérebros idosos saudáveis.

ABSTRACT This prospective study aimed to evaluate the influence of the -351A/G XbaI polymorphism in the estrogen receptor-alpha (ESR-1) gene on global cognitive scores of a community sample of healthy oldest-old individuals within one year of follow up. Methods The individuals were categorized in two groups according to the presence or absence of cognitive decline. Cognitive data were related to genetic information. Results The XbaI -351 AA genotype was more common among cognitive decliners, while -351G allele carriers showed cognitive stability or improvement. Conclusion These results suggest that ESR-1 could be associated with one-year cognitive decline in healthy oldest-old individuals, since the estrogen pathway may be involved with neuroprotection, even in healthy brain aging.
