Abstract Regular physical exercise is considered an effective method for preserving and improving balance in elderly women. However, it is unclear whether resistance and aerobic exercises have the same effect on balance in elderly women. With this in mind, the aim of this study is to compare the effects of resistance and aerobic training on balance and concern about falls in elderly women. For this purpose, elderly women from the resistance training group (RTG; n = 15) and the aerobic exercise group (AEG; n = 15) had their physical activity level, balance and concern about falls evaluated. No significant differences were observed between the groups in physical activity level (χ²= 0.240; gl= 1; p<0.624). However, the elderly women from the RTG showed better performance in the balance test (49.8±3.85) and low concern about possible falls (18.3±1.44), when compared to the elderly women from the AEG (balance: 28 .13±4.24; χ² Wald (1) = 176.778; p<0.0001; concern about possible falls: 33.0±5.93; χ² Wald (1) = 87.5; p<0.001). In view of this, we can conclude that elderly women who practiced resistance training showed better balance and less concern about possible falls compared to those who practiced aerobic exercises.

Resumo A prática regular de exercício físico tem sido considera uma conduta eficiente para melhorar o equilíbrio de idosos. Porém, não está muito claro se os exercícios físicos resistido e aeróbio resultam no mesmo efeito sobre o equilíbrio em mulheres idosas. Pensando nisso, o objetivo deste estudo foi comparar os efeitos dos treinamentos resistido e aeróbio sobre o equilíbrio e a preocupação com quedas em idosas. Para tal, foram avaliadas idosas do grupo treinamento resistido (GTR; n = 15) e do grupo aeróbio (GEA; n = 15). Foram mensurados o nível de atividade física, o equilíbrio e a preocupação com a queda. Nenhuma diferença significativa entre grupos foi observada no nível de atividade física (χ²= 0,240; gl= 1; p<0,624). Porém, as idosas do GTR apresentaram melhor desempenho no teste de equilíbrio (49,8±3,85) e baixa preocupação com uma possível queda (18,3±1,44), quando comparadas com as idosas do GEA (equilíbrio: 28,13±4,24; χ² Wald (1) = 176,778; p<0,0001; preocupação com uma possível queda: 33,0±5,93; χ² Wald (1) = 87,5; p<0,001). No presente estudo, podemos concluir que idosas praticantes de treinamento resistido apresentaram melhor equilíbrio e menor preocupação com uma possível queda em relação às idosas praticantes de exercício aeróbio.

Resumo: Este estudo buscou identificar a composição da ictiofauna do rio Muzambinho, um tributário de terras altas do Rio Paraná. Também buscamos investigar se as cachoeiras da região podem servir de barreiras para dispersão de espécies de peixes. Para isso, foram realizadas coletas em 34 pontos do Rio Muzambinho, com diferentes técnicas. Ao todo foram registradas 37 espécies de peixes, sendo algumas endêmicas e a maioria nativa. Dentre essas espécies algumas são predominantes em locais degradados e podem ser usadas como bioindicadores. Os resultados também demonstram que há uma zonação na composição ictiofaunística no Muzambinho que segrega a fauna em três sessões separadas por cachoeiras, Baixo Muzambinho, Alto Muzambinho e São Domingos. Concluímos que para a ideal preservação da ictiofauna do rio Muzambinho é necessária a preservação independente de suas sessões o que garantiria a manutenção de linhagens naturalmente isoladas.

Abstract: This study sought to identify the ichthyofauna composition of the Muzambinho River, an upland tributary of the Paraná River. We also investigate whether waterfalls in the region can serve as barriers to the dispersal of fish species. For this purpose, collections were carried out at 34 points on the Muzambinho River using different techniques. In all, 37 species were recorded, some of which were endemic, and the majority were native. Among these species, some are predominant in degraded places and can be used as bioindicators. The results also demonstrate zonation in the ichthyofauna composition in Muzambinho that segregates the fauna into three sessions separated by waterfalls: Lower Muzambinho, Upper Muzambinho, and Sao Domingos. We conclude that, for the ideal preservation of the ichthyofauna of the Muzambinho River, it is necessary to preserve its sections independently, which would guarantee the maintenance of naturally isolated strains.

RESUMO CONTEXTO: As doenças inflamatórias intestinais (DII) são afecções inflamatórias crônicas de caráter recorrente, cujas taxas de incidência e prevalência têm aumentado, inclusive no Brasil. A longo prazo, são responsáveis por danos estruturais que impactam na qualidade de vida, morbidade e mortalidade dos pacientes. OBJETIVO: Avaliar o perfil dos médicos que atendem pacientes com DII, assim como as características deste atendimento, demandas não atendidas e dificuldades. MÉTODOS: Um questionário contendo 17 variáveis foi elaborado e enviado para médicos, selecionados a partir do cadastro da Comissão das Estaduais do Grupo de Estudos da Doença Inflamatória Intestinal do Brasil (GEDIIB), totalizando 286 médicos de 101 cidades brasileiras distribuídas por 21 estados e Distrito Federal. RESULTADOS: A maioria dos médicos que respondeu o questionário foram Gastroenterologistas e Coloproctologistas. Mais de 60% tinham até 20 anos de atuação na especialidade e 53,14% trabalhavam em três locais ou mais. A dificuldade no acesso ou liberação de medicamentos ficou evidenciada neste questionário, assim como a dificuldade no encaminhamento para profissionais não médicos que atuam em DII. Mais de 75% dos médicos relataram dificuldades para realização de enteroscopia por duplo balão e cápsula endoscópica, e 67,8% para realização da calprotectina. Em relação ao número de pacientes atendidos por cada médico, foi evidenciado que não há uma concentração de pacientes sob a responsabilidade de poucos médicos. O infliximabe e o adalimumabe foram os biológicos mais utilizados e ficou evidenciada prescrição maior de derivados de 5-ASA para retocolite ulcerativa quando comparada à doença de Crohn. Os corticoides foram prescritos para uma parcela menor de pacientes em ambas doenças. Os temas “falha a terapia biológica” e “novas drogas” foram referidos como aqueles com maior prioridade para discussão em eventos científicos. Em relação às possíveis diferenças entre cada região e o restante do país, os médicos da região Norte relataram maior dificuldade no acesso a exames complementares e os médicos da região Nordeste, maior dificuldade no acesso ou liberação de medicamentos. CONCLUSÃO: Os dados obtidos por meio deste estudo mostram o perfil do atendimento médico especializado em DII e podem se constituir em ferramenta útil para para elaboração de políticas governamentais e para sociedade brasileira como um todo.

ABSTRACT BACKGROUND: Inflammatory bowel diseases (IBD) are chronic inflammatory affections of recurrent nature whose incidence and prevalence rates have increased, including in Brazil. In long term, they are responsible for structural damage that impacts quality of life, morbidity and mortality of patients. OBJECTIVE: To describe the profile of physicians who treat IBD patients as well as the characteristics of IBD care, unmet demands and difficulties. METHODS: A questionnaire containing 17 items was prepared and sent to 286 physicians from 101 Brazilian cities across 21 states and the Federal District, selected from the register of the State Commission of the “Study Group of Inflammatory Bowel Disease of Brazil” (GEDIIB). RESULTS: The majority of the physicians who answered the questionnaire were gastroenterologists and colorectal surgeons. More than 60% had up to 20 years of experience in the specialty and 53.14% worked at three or more locations. Difficulties in accessing or releasing medicines were evident in this questionnaire, as was referrals to allied healthy professionals working in IBD-related fields. More than 75% of physicians reported difficulties in performing double-balloon enteroscopy and capsule endoscopy, and 67.8% reported difficulties in measuring calprotectin. With regard to the number of patients seen by each physician, it was shown that patients do not concentrate under the responsibility of few doctors. Infliximab and adalimumab were the most commonly used biological medicines and there was a higher prescription of 5-ASA derivatives for ulcerative colitis than for Crohn’s disease. Steroids were prescribed to a smaller proportion of patients in both diseases. The topics “biological therapy failure” and “new drugs” were reported as those with higher priority for discussion in medical congresses. In relation to possible differences among the country’s regions, physicians from the North region reported greater difficulty in accessing complementary exams while those from the Northeast region indicated greater difficulty in accessing or releasing medicines. CONCLUSION: The data obtained through this study demonstrate the profile of specialized medical care in IBD and are a useful tool for the implementation of government policies and for the Brazilian society as a whole.

Abstract Introduction: Coronary artery bypass grafting (CABG) is the most frequently performed heart surgery in Brazil. Recent international guidelines recommend that national societies establish a database on the practice and results of CABG. In anticipation of the recommendation, the BYPASS Registry was introduced in 2015. Objective: To analyze the profile, risk factors and outcomes of patients undergoing CABG in Brazil, as well as to examine the predominant surgical strategy, based on the data included in the BYPASS Registry. Methods: A cross-sectional study of 2292 patients undergoing CABG surgery and cataloged in the BYPASS Registry up to November 2018. Demographic data, clinical presentation, operative variables, and postoperative hospital outcomes were analyzed. Results: Patients referred to CABG in Brazil are predominantly male (71%), with prior myocardial infarction in 41.1% of cases, diabetes in 42.5%, and ejection fraction lower than 40% in 9.7%. The Heart Team indicated surgery in 32.9% of the cases. Most of the patients underwent cardiopulmonary bypass (87%), and cardioplegia was the strategy of myocardial protection chosen in 95.2% of the cases. The left internal thoracic artery was used as a graft in 91% of the cases; the right internal thoracic artery, in 5.6%; and the radial artery in 1.1%. The saphenous vein graft was used in 84.1% of the patients, being the only graft employed in 7.7% of the patients. The median number of coronary vessels treated was 3. Operative mortality was 2.8%, and the incidence of cerebrovascular accident was 1.2%. Conclusion: CABG data in Brazil provided by the BYPASS Registry analysis are representative of our national reality and practice. This database constitutes an important reference for indications and comparisons of therapeutic procedures, as well as to propose subsequent models to improve patient safety and the quality of surgical practice in the country.

Abstract Objective: To report the early results of the BYPASS project - the Brazilian registrY of adult Patient undergoing cArdiovaScular Surgery - a national, observational, prospective, and longitudinal follow-up registry, aiming to chart a profile of patients undergoing cardiovascular surgery in Brazil, assessing the data harvested from the initial 1,722 patients. Methods: Data collection involved institutions throughout the whole country, comprising 17 centers in 4 regions: Southeast (8), Northeast (5), South (3), and Center-West (1). The study population consists of patients over 18 years of age, and the types of operations recorded were: coronary artery bypass graft (CABG), mitral valve, aortic valve (either conventional or transcatheter), surgical correction of atrial fibrillation, cardiac transplantation, mechanical circulatory support and congenital heart diseases in adults. Results: 83.1% of patients came from the public health system (SUS), 9.6% from the supplemental (private insurance) healthcare systems; and 7.3% from private (out-of -pocket) clinic. Male patients comprised 66%, 30% were diabetics, 46% had dyslipidemia, 28% previously sustained a myocardial infarction, and 9.4% underwent prior cardiovascular surgery. Patients underwent coronary artery bypass surgery were 54.1% and 31.5% to valve surgery, either isolated or combined. The overall postoperative mortality up to the 7th postoperative day was 4%; for CABG was 2.6%, and for valve operations, 4.4%. Conclusion: This first report outlines the consecution of the Brazilian surgical cardiac database, intended to serve primarily as a tool for providing information for clinical improvement and patient safety and constitute a basis for production of research protocols.

Abstract: En | Text: En | PDF: En

Kaposi's sarcoma is a multifocal vascular lesion of low-grade potential that is most often present in mucocutaneous sites and usually also affects lymph nodes and visceral organs. The condition may manifest through purplish lesions, flat or raised with an irregular shape, gastrointestinal bleeding due to lesions located in the digestive system, and dyspnea and hemoptysis associated with pulmonary lesions. In the early 1980s, the appearance of several cases of Kaposi's sarcoma in homosexual men was the first alarm about a newly identified epidemic, acquired immunodeficiency syndrome. In 1994, it was finally demonstrated that the presence of a herpes virus associated with Kaposi's sarcoma called HHV-8 or Kaposi's sarcoma herpes virus and its genetic sequence was rapidly deciphered. The prevalence of this virus is very high (about 50%) in some African populations, but stands between 2% and 8% for the entire world population. Kaposi's sarcoma only develops when the immune system is depressed, as in acquired immunodeficiency syndrome, which appears to be associated with a specific variant of the Kaposi's sarcoma herpes virus. There are no treatment guidelines for Kaposi's sarcoma established in Brazil, and thus the Brazilian Society of Clinical Oncology and the Brazilian Society of Infectious Diseases developed the treatment consensus presented here.

Nos últimos anos o DNA barcoding surgiu como uma ferramenta rápida, precisa e eficiente para identificar espécies. Considerando a dificuldade na identificação de algumas espécies de Parodontidae da bacia do rio da Prata e da ausência de dados moleculares para o grupo, testamos a eficácia do código de barras de DNA e discutimos a importância do uso de diferentes abordagens para resolver problemas taxonômicos. Oito espécies foram analisadas com sequencias parciais do gene citocromo c oxidase I. A distância genética média K2P intraespecífica foi de 0,04% comparado com 4,2% para distância genética média K2P interespecífica. As análises de distância mostraram dois pares de espécies com divergência genética K2P inferior a 2%, mas o suficiente para separar estas espécies. Apareiodon sp. e A. ibitiensis, consideradas a mesma espécie por alguns autores, mostraram 4,2% de divergência genética, confirmando serem espécies diferentes. Amostras de A. affinis dos rios Uruguai e Paraguai apresentaram 0,3% de divergência genética, indicando um maior grau de relação entre elas, no entanto, esses exemplares divergiram em 6,1% em relação aos exemplares do alto rio Paraná, o que indica que estes últimos representam uma espécie potencialmente nova. Os resultados mostraram a eficácia do método de DNA barcoding na identificação das espécies analisadas, os quais, em conjunto com os dados morfológicos e citogenéticos disponíveis auxiliam na identificação inequívoca das espécies.

In the past years, DNA barcoding has emerged as a quick, accurate and efficient tool to identify species. Considering the difficulty in identifying some Parodontidae species from the La Plata basin and the absence of molecular data for the group, we aimed to test the effectiveness of DNA barcoding and discuss the importance of using different approaches to solve taxonomic problems. Eight species were analyzed with partial sequences of Cytochrome c oxidase I. The mean intraspecific K2P genetic distance was 0.04% compared to 4.2% for mean interspecific K2P genetic distance. The analyses of distance showed two pairs of species with K2P genetic divergence lower than 2%, but enough to separate these species. Apareiodon sp. and A. ibitiensis, considered as the same species by some authors, showed 4.2% genetic divergence, reinforcing their are different species. Samples of A. affinis from the Uruguay and Paraguay rivers presented 0.3% genetic divergence, indicating a close relationship between them. However, these samples diverged 6.1% from the samples of the upper Paraná River, indicating that the latter represents a potentially new species. The results showed the effectiveness of the DNA barcoding method in identifying the analyzed species, which, together with the morphological and cytogenetic available data, help species identification.

Foram realizadas análises citogenéticas e moleculares em representantes do gênero Piabina. O estudo envolveu especificamente as espécies P. argentea e P. anhembi coletadas nas áreas das bacias hidrográficas dos rios Paranapanema e Tietê (Brasil). Os dados sugerem que a espécie P. argentea coletada nas bacias dos rios Paranapanema e Tietê podem representar mais de uma espécie. As amostras analisadas diferem por particularidades citogenéticas e nas análises moleculares utilizando-se sequências parciais dos genes COI e CytB, revelando três grupos distintos de P. argentea com distâncias genéticas suficientes para sustentar a conclusão de que as três amostras analisadas são unidades taxonômicas distintas.

Cytogenetic and molecular analyses were carried out in fish representative of the genus Piabina. This study specifically involved the species P. argentea and P. anhembi collected from areas of the Paranapanema and Tietê River basins, Brazil. Our findings suggest that fish classified as Piabina argentea in the Paranapanema and Tietê Rivers may represent more than one species. The samples analyzed differed by cytogenetic particularities and molecular analyses using partial sequences of the genes COI and CytB as genetic markers revealed three distinct groups of P. argentea with genetic distances sufficient to support the conclusion that the three samples analyzed are three distinct taxonomic units.

Objetivou-se no presente estudo, estimar a diversidade genética entre 75 clones F1, 19 variedades locais ou "landraces" e seis cultivares comerciais, sugerir com base na dissimilaridade e no desempenho agronômico, subamostras com potencial para uso em programas de hibridação ou como cultivares e estimar a contribuição relativa de cada característica fenotípica para a diversidade. As subamostras foram avaliadas por meio de sete caracteres quantitativos relacionadas à parte aérea e à produção de raízes tuberosas em experimento realizado em Lavras, Minas Gerais. O delineamento utilizado foi um látice simples 10x10, com parcelas de 2,4 m² e quatro plantas úteis. A divergência genética foi expressa por meio da distância generalizada de Mahalanobis, com posterior agrupamento das subamostras pelo método de otimização de Tocher. A contribuição relativa das características para a diversidade baseou-se no método de Singh (1981). Há divergência genética entre as subamostras estudadas, sendo as subamostras 60, 61, 66 e 67 potencialmente úteis a participarem de fases seguintes em um programa de melhoramento. O rendimento de biomassa da parte aérea e o número de raízes tuberosas por planta foram mais importantes para a discriminação das subamostras.

The objective of the present study was to estimate the genetic diversity among 75 F1 clones, 19 landraces and six commercial cultivars and to suggest on the basis of dissimilarity and the agronomic performance the accessions potential by use full as cultivars or for breeding programs. In addition this study aimed at to estimate the relative contribution of phenotypic traits for the diversity. The accessions were evaluated using seven quantitative traits related to shoot and roots production in experimental trial conducted in Lavras, Minas Gerais State. The design was a simple lattice 10x10, in which plots of 2.4 m², and four useful plants. The genetic diversity was expressed by the generalized Mahalanobis distance, with subsequent grouping of the accessions by Tocher's optimization procedure. The relative contribution of traits to the diversity based method of Singh (1981). There are genetic differences between the accessions studied. The accessions 60, 61, 66 and 67 are potentially useful to participate in phases in a breeding program. The yield of shoots biomass and roots number per plant were more important for accession discrimination.

Abstract: En | Text: En | PDF: En

Catfishes of the genus Pseudoplatystoma are very important species due to both their high commercial value and their ecological role as voracious predators. They undertake lengthy migratory movements during their life-cycle, this including reproductive migration which occurs from October to December in the rainy season. In the present study, seven microsatellite loci were analyzed to access genetic variability in two samples of P. reticulatum from the Upper Paraguay Basin. The loci were highly polymorphic (mean = 7.28). According to all analysis, the two samples of P. reticulatum revealed pronounced genetic differentiation. Fst value was 0.2290, Rst value 0.1067 and AMOVA 22.90% (Fst) and 10.67% (Rst), all being highly significant (p < 0.001). The division of the fishes into two groups was confirmed by microsatellite multi-locus Bayesian assignment testing. The results obtained present evidence of genetic structuring in a P. reticulatum population.
