ABSTRACT The piramutaba, Brachyplatystoma vaillantii is a freshwater catfish that is the most abundant fishery resource in the Amazon estuary. Piramutaba trawling is done on industrial fishing scale and is characterized by the presence of many freshwater and marine bycatch species, with and without commercial value. Here we describe the bycatch of the industrial fishery of piramutaba in the Amazon estuary and evaluate the relationship of two important environmental factors, depth and salinity, with the accidental capture of freshwater and marine fishes in the Amazon estuary in the rainy and dry seasons. We identified 21 cartilaginous fish species (19.1% freshwater and 80.9% marine) and 125 bony fish species (25.6% freshwater and 74.4% marine). The bycatch included 64 species without commercial value (43% of all bycatch species), which are always discarded. Freshwater and estuarine fishes exhibited significantly higher abundances in shallower environments, while marine fishes were similarly abundant along the entire depth gradient. On the contrary, the abundance of freshwater fishes significantly decreased, and that of estuarine and marine fishes significantly increased with increasing salinity. Regarding the conservation status of the bycatch species, one is classified as vulnerable (VU), and seven as critically endangered (CR). The information on the bycatch of piramutaba fishery in the Amazon estuary is important to subsidize regional fisheries policies and the management of protected areas.

RESUMO A piramutaba, Brachyplatystoma vaillantii é um bagre de água doce que representa o recurso pesqueiro mais abundante no estuário amazônico. O arrasto da piramutaba é feito em escala industrial, caracterizado pela presença de muitas espécies de água doce e marinha capturadas de forma incidental, com e sem valor comercial. Aqui descrevemos a captura incidental da pesca industrial de piramutaba no estuário amazônico e avaliamos a relação de dois fatores ambientais, profundidade e salinidade, com a captura incidental de espécies de água doce e marinhas nas estações chuvosa e seca. Identificamos 21 espécies de peixes cartilaginosos (19,1% de água doce e 80,9% marinhos) e 125 espécies de peixes ósseos (25,6% de água doce e 74,4% marinhos). A captura incidental incluiu 64 espécies sem valor comercial (43% de todas as espécies capturadas) que sempre são descartadas. Os peixes de água doce e estuarinos exibiram abundâncias significativamente maiores em ambientes mais rasos, enquanto os peixes marinhos foram igualmente abundantes ao longo de todo o gradiente de profundidade. Inversamente, a abundância de peixes de água doce diminuiu significativamente, e a de peixes estuarinos e marinhos aumentou significativamente em salinidades maiores. Em relação ao estado de conservação das espécies capturadas, uma é reconhecida como vulnerável (VU) e sete como criticamente ameaçadas (CR). As informações sobre a captura incidental da pesca da piramutaba no estuário amazônico são fundaentais para subsidiar políticas pesqueiras regionais e gestão de áreas protegidas.

Abstract Objective To verify the performance of the Net Promoter Score (NPS) as a tool to assess parental satisfaction in pediatric intensive care units (PICUs). Methods The authors conducted an observational cross-sectional multicenter study in the PICUs of 5 hospitals in Brazil. Eligible participants were all parents or legal guardians of PICU-admitted children, aged 18 years or over. The NPS was administered together with the EMpowerment of PArents in THe Intensive Care (EMPATHIC-30), used as the gold standard, and a sociodemographic questionnaire. For analysis, the results were dichotomized into values greater than or equal to the median of the tests. The associations between the 2 tools were evaluated and the distribution of their results was compared. Results The parents or legal guardians of 78 PICU-admitted children were interviewed. Of the respondents, 85% were women and 62% were in a private hospital. The median NPS was 10 (IQR, 10-10), and the median EMPATHIC-30 score was 5.7 (IQR, 5.4-5.9). Compared with the gold standard, the NPS had a sensitivity of 100% at all cutoff points, except at cutoff 10, where the sensitivity was slightly lower (97.5%). As for specificity, NPS performance was poorer, with values ranging from 0% (NPS ≥ 5) to 47.4% (NPS = 10). Conclusions NPS proved to be a sensitive tool to assess parental satisfaction, but with poor ability to identify dissatisfied users in the sample.

RESUMO Objetivo Avaliar a sequência de ressonância magnética blood-oxygen-level-dependent (BOLD) realizada em um equipamento 3 Tesla para medir a biodisponibilidade do oxigênio do tecido pelo valor de R2* na diferenciação de necrose tubular aguda e rejeição aguda, comparando à biópsia renal (padrão-ouro). Métodos Estudo unicêntrico, prospectivo, com pacientes submetidos a transplante renal de 2013 a 2014, que desenvolveram disfunção do enxerto menos de 4 semanas após o transplante. Todos os pacientes foram submetidos à ressonância magnética abdominal 3 Tesla com o mesmo protocolo, seguida de duas sequências BOLD e biópsia renal. Resultados Foram incluídos 12 homens (68,75%) e três mulheres (31,25%). Foram realizadas 19 biópsias renais percutâneas (quatro pacientes necessitaram de segunda biópsia devido à alteração nos achados clínicos). Os resultados histopatológicos incluíram dez casos de necrose tubular aguda, quatro de rejeição aguda e cinco casos de outros diagnósticos (miscelânea). A comparação entre os quatro grupos de interesse não mostrou diferenças significativas em relação ao R2* no córtex (p=0,177). Quanto ao R2* da medula, observaram-se diferenças significativas (p=0,033), com miscelânea e necrose tubular aguda apresentando valores mais baixos quando comparados aos demais. Conclusão A ressonância magnética BOLD 3 Tesla é uma técnica viável que indiretamente utiliza a concentração de oxigênio no tecido em enxertos renais e pode ser usada para a diferenciação entre rejeição aguda e necrose tubular aguda.

ABSTRACT Objective To evaluate the ability of blood-oxygen-level-dependent (BOLD) magnetic resonance imaging at 3 Tesla to measure tissue oxygen bioavailability based on R2* values, and to differentiate between acute tubular necrosis and acute rejection compared to renal biopsy (gold standard). Methods A prospective, single-center study, with patients submitted to renal transplantation between 2013 and 2014, who developed graft dysfunction less than 4 weeks after transplantation. All patients were submitted to abdominal magnetic resonance imaging at 3 Tesla using the same protocol, followed by two BOLD sequences and kidney biopsy. Results Twelve male (68.75%) and three female (31.25%) patients were included. A total of 19 percutaneous renal biopsies were performed (four patients required a second biopsy due to changes in clinical findings). Pathological findings revealed ten cases of acute tubular necrosis, four cases of acute rejection, and five cases with other (miscellaneous) diagnoses. Comparison between the four groups of interest failed to reveal significant differences (p=0.177) in cortical R2* values, whereas medullary R2* values differed significantly (p=0.033), with lower values in the miscellaneous diagnoses and the acute tubular necrosis group. Conclusion BOLD magnetic resonance imaging at 3 Tesla is a feasible technique that uses indirect tissue oxygen level measurements to differentiate between acute rejection and acute tubular necrosis in renal grafts.

RESUMO CONTEXTO: A efetividade da colonoscopia no rastreamento do câncer colorretal (CCR) depende de indicadores de qualidade, sendo a taxa de detecção de adenoma (TDA) a mais importante. A taxa de detecção de pólipos serrilhados proximais (TDPSp) tem sido estudada como um potencial indicador de qualidade para a colonoscopia. OBJETIVO: O objetivo é analisar e comparar a diferença de TDA e TDPSp entre pacientes submetidos à colonoscopia de rastreamento e uma população não selecionada com outras indicações para colonoscopia, incluindo vigilância e diagnóstico. MÉTODOS: Esta é uma coorte histórica de pacientes submetidos à colonoscopia no serviço de endoscopia digestiva de um hospital terciário. Das 1554 colonoscopias realizadas, 573 pacientes foram excluídos. Os 981 pacientes restantes foram divididos em dois grupos: pacientes submetidos à colonoscopia de rastreamento (n=428; 43,6%); pacientes com outras indicações, incluindo vigilância e diagnóstico (n=553; 56,4%). RESULTADOS: A taxa de detecção de adenoma do grupo com outras indicações (50,6%) foi superior à do grupo de rastreamento (44,6%; P=0,03). Em relação ao TDPSp, não houve diferença entre os dois grupos (triagem 13,6%; outras indicações 13,7%; P=0,931). Não houve diferença significativa na idade média (P=0,259) ou na proporção de homens e mulheres (P=0,211) entre os grupos. CONCLUSÃO: A taxa de detecção proximal de pólipos serrilhados mostrou uma diferença insignificante entre os grupos com diferentes indicações para colonoscopia e poderia ser utilizada como um indicador complementar a TDA. Isso beneficiaria colonoscopistas com baixo volume de colonoscopias ou baixo volume de colonoscopias de rastreamento.

ABSTRACT BACKGROUND: The effectiveness of colonoscopy for colorectal cancer (CRC) screening depends on quality indicators, which adenoma detection rate (ADR) being the most important. Proximal serrated polyp detection rate (pSPDR) has been studied as a potential quality indicator for colonoscopy. OBJECTIVE: The aim is to analyze and compare the difference in ADR and pSPDR between patients undergoing screening colonoscopy and an unselected population with other indications for colonoscopy, including surveillance and diagnosis. METHODS: This is a historical cohort of patients who underwent colonoscopy in the digestive endoscopy service of a tertiary hospital. Out of 1554 colonoscopies performed, 573 patients were excluded. The remaining 981 patients were divided into two groups: patients undergoing screening colonoscopy (n=428; 43.6%); patients with other indications including surveillance and diagnosis (n=553; 56.4%). RESULTS: Adenoma detection rate of the group with other indications (50.6%) was higher than that of the screening group (44.6%; P=0.03). In regarding pSPDR, there was no difference between pSPDR in both groups (screening 13.6%; other indications 13.7%; P=0.931). There was no significant difference in the mean age (P=0.259) or in the proportion of men and women (P=0.211) between both groups. CONCLUSION: Proximal serrated polyp detection rate showed an insignificant difference between groups with different indications and could be used as a complementary indicator to adenoma detection rate. This could benefit colonoscopists with low colonoscopy volume or low volume of screening colonoscopies.

Abstract Background: Primary care physicians have difficulty dealing with patients who have HF with preserved LVEF(HFpEF). The prognosis of HFpEF is poor, and difficult to predict on primary care. Objective: The aim of the study is to apply the H2FPEF score to primary care patients and verify its power to assess the risk of death or hospitalization due to cardiovascular disease. Methods: This longitudinal study included 402 individuals, with signs or symptoms of HF, aged≥45 years and, underwent an evaluation which included clinical examination, BNP and echocardiogram. The diagnosis of HFpEF was confirmed by the criteria of the European Society of Cardiology. After five years, the patients were reassessed as to the occurrence of the composite outcome, death from any cause or hospitalization for cardiovascular disease. H2FPEF used six variables: body mass index, medications for hypertension, age, pulmonary artery systolic pressure, atrial fibrillation and E/e' ratio ranged from 0 to 9 points. The level of statistical significance was p<0.05. Results: HFpEF was diagnosed in 58(14.4%). Among patients with H2FPEF≥4, 30% had HFpEF and in those with a score≤4, HFpEF was present in 12%. Patients with HFpEF and H2FPEF≥4 had 53% of outcomes, whereas patients with HFpEF and a score ≤4 had a 21% of outcomes. BNP values were higher in patients with HFpEF compared to those without HFpEF(p<0.0001). Conclusion: H2FPEF≥4 indicated a worse prognosis in patients with HFpEF assisted in primary care. H2FPEF may be a simple and useful tool for risk stratification in patients with HFpEF at the primary care.

Resumen Antecedentes: La hipertensión es responsable de un gran número de muertes debido a cardiopatías e ictus. Un paso esencial para su control es la identificación de factores modificables predictivos de la hipertensión. Objetivos: Calcular la relación entre ingesta de sal, ácido úrico sérico e hipertensión incidental en un centro de atención primaria. Métodos: Cohorte retrospectiva del estudio CAMELIA, en el que se incluyó una muestra no aleatorizada de 1.098 participantes con edades ≥ 20 años, obtenida de un programa de atención primaria. Originalmente, la muestra incluía sujetos hipertensos, diabéticos y no diabéticos/no hipertensos. Para el análisis, se estudiaron 258 participantes con presión arterial (PA) inferior a 140/90 mm Hg, sin prescripción de fármacos antihipertensivos, y no diabéticos. Transcurridos cinco años de la primera visita, se revisaron sus historias médicas. Se dividió a los pacientes en dos grupos, con arreglo a su PA en la primera visita: grupo con PA normal (PA sistólica ≤ 120 mm Hg y PA diastólica ≤ 80 mm Hg), y grupo con PA alta-normal BP (PA sistólica 121-139 mm Hg y/o PA diastólica 81-89 mm Hg). Resultados: En el análisis multivariante, la PA alta-normal, hiperuricemia e ingesta de sal ≥ 6 g/día predijeron la hipertensión incidental. En los participantes del grupo de PA normal, la ingesta elevada de sal confirió el mayor riesgo. En el grupo de PA alta-normal, el tabaquismo y el ácido úrico sérico fueron los factores más importantes. Conclusión: En una población sana, multiétnica y normotensa, procedente de un programa de atención primaria urbana la PA alta-normal, hiperuricemia e ingesta elevada de sal constituyeron los factores predictivos de la hipertensión incidental.

Abstract Background: Hypertension is responsible for a substantial number of deaths due to cardiovascular disease and stroke. A crucial step toward its control is the identification of modifiable predictors of hypertension. Objectives: To estimate the relationship between salt intake, serum uric acid and incident hypertension in a primary care setting. Methods: Retrospective cohort of the CAMELIA study in which a non-randomized sample of 1098 participants who were ≥ 20 year-old was recruited from a primary care program. Originally, the sample consisted of hypertensive, diabetic and non-diabetic/non-hypertensive subjects. For the analysis, 258 participants with blood pressure (BP) lower than 140/90 mm Hg not using antihypertensive drugs and without diabetes mellitus were included. Five years after the first visit, their medical records were reviewed. Patients were divided into two groups according to BP in the first visit: normal BP group (systolic BP ≤ 120 mm Hg and diastolic BP ≤ 80 mm Hg) and high-normal BP group (systolic BP 121-139 mm Hg and/or diastolic BP 81-89 mm Hg). Results: In multivariate analysis, high-normal BP, hyperuricemia and salt intake ≥ 6 g/day predicted incident hypertension. In participants of thenormal BP group, high salt intake conferred the highest risk. In the high-normal BP group, smoking and serum uric acid were found to be the most important ones. Conclusion: In a healthy, multiethnic, and normotensive population from an urban primary care program, high-normal BP, hyperuricemia and high salt intake were found to be predictors of incident hypertension.

Resumen Introducción: La disnea es el síntoma más común en la insuficiencia cardíaca. En los ancianos es común en la enfermedad pulmonar obstructiva crónica y la depresión. Objetivo: Estimar la prevalencia de disnea de esfuerzo, ortopnea y disnea paroxística nocturna y su asociación con enfermedades crónicas en la atención primaria. Métodos: Estudio transversal, parte del estudio Digitalis, que incluyó a 633 individuos, entre 45 y 99 años de edad, registrados en un programa de atención primaria en Niterói, Brasil. Todos los participantes se sometieron a evaluaciones clínicas, recolección de sangre y orina, y respondieron a un cuestionario en un solo día. Se usaron autorrelatos para el diagnóstico de las enfermedades. Resultados: De los 633 individuos, el 30% presentó disnea. En el análisis crudo la enfermedad pulmonar obstructiva crónica mostró las asociaciones más fuertes con los tres tipos de disnea, seguidos por la depresión y la insuficiencia cardíaca. La enfermedad pulmonar obstructiva crónica, evaluada de forma aislada, no presentó ningún caso de disnea paroxística nocturna, y la insuficiencia cardíaca por sí sola mostró una relación muy fuerte con este tipo de disnea. Conclusiones: El comportamiento diferente de las asociaciones de los tipos de disnea con las principales enfermedades crónicas en pacientes en atención primaria puede ayudar a una mejor caracterización de los pacientes con insuficiencia cardíaca.

Abstract Background: Dyspnea is the most common symptom in heart failure. In the elderly, it is common in chronic obstructive pulmonary disease and depression. Objective: To estimate the prevalence of dyspnea on exertion, orthopnea and paroxysmal nocturnal dyspnea and its association with chronic diseases in primary care. Methods: A cross-sectional study, part of the Digitalis Study, including 633 individuals, between 45 to 99 years old, registered in a primary care program in Niteroi, Brazil. All participants underwent clinical evaluations, blood and urine collection, and responded to a questionnaire in a single day. Self-reports were used for the diagnosis of diseases. Results: Of the 633 individuals, 30% had dyspnea. In the crude analysis, chronic obstructive pulmonary disease showed the strongest associations with the three types of dyspnea, followed by depression and heart failure. Chronic obstructive pulmonary disease alone did not present any cases of paroxysmal nocturnal dyspnea, and heart failure alone showed a very strong relationship with this type of dyspnea. Conclusions: The different behavior of the associations of the types of dyspnea with major chronic diseases in patients in primary care can help in the better characterization of patients with heart failure.

Resumo Fundamento: O remodelamento ventricular esquerdo (RVE) está relacionado a desfechos não fatais e fatais. Objetivo: Descrever os padrões geométricos do VE e suas associações. Métodos: Um total de 636 indivíduos entre 45 e 99 anos no Rio de Janeiro, Brasil, foi submetido a avaliação clínica, exames laboratoriais, eletrocardiograma e ecocardiograma com Doppler tecidual (EDT). A diferença entre as categorias foi testada com Kruskall-Wallis com testes post hoc, uma vez que todas as variáveis estudadas não são normalmente distribuídas e o qui-quadrado de Pearson (variáveis categóricas). As ORs brutas e ajustadas foram estimadas por regressão logística. O nível de significância foi de 5% para todos os testes. Os indivíduos tinham RVE caracterizada como: geometria normal (GN), remodelamento concêntrico (RC), hipertrofia concêntrica (HC) e hipertrofia excêntrica (HE). Resultados: A prevalência de padrões alterados foi de 33%. Os sujeitos apresentaram GN (n = 423; 67%); HE (n = 186; 29%); HC (n = 14; 2%); e RC (n = 13; 2%). As variáveis sexo, idade, escolaridade e razão albumina/creatinina (A/C) mostraram relação com a chance de HE, mesmo após o ajuste. Conclusão: Aproximadamente um terço dos indivíduos estudados apresentavam RVE e corriam risco de desenvolver insuficiência cardíaca. A/C alterada na urina foi associada à HE, indicando uma relação precoce entre disfunção cardíaca e renal.

Abstract Background: Left ventricular remodeling (LVR) is related to both non-fatal and fatal outcomes. Objective: To describe the geometric patterns of the LV and their associations. Methods: A total of 636 individuals between the ages of 45 and 99 years in Rio de Janeiro, Brazil, were submitted to clinical evaluation, laboratory tests, electrocardiogram, and tissue Doppler echocardiography (TDE). The difference between categories was tested with Kruskall-Wallis with post hoc tests, once all variables studied are non-normally distributed and Pearson’s Qui-square (categorical variables). Gross and adjusted ORs were estimated by logistic regression. The level of significance was 5% for all tests. Subjects had LVR characterized as: normal geometry (NG), concentric remodeling (CR), concentric hypertrophy (CH), and eccentric hypertrophy (EH). Results: The prevalence of altered patterns was 33%. Subjects presented NG (n = 423; 67%); EH (n = 186; 29%); CH (n = 14; 2%); and CR (n = 13; 2%). The variables of gender, age, level of education and albumin/creatinine ratio (A/C), showed a relationship with the chance of EH even after adjustment. Conclusion: Approximately one third of the studied individuals had LVR and were at risk for developing heart failure. Altered A/C in urine was associated with EH, indicating an early relationship between cardiac and renal dysfunction.

Resumo Objetivo: A presente pesquisa buscou analisar se os indicadores de mercado, de forma complementar aos indicadores contábeis, têm capacidade de antecipar alterações (downgrades ou upgrades) nas avaliações de classificação de risco (rating) dos bancos no Brasil. Metodologia: Regressões lineares em modelos probit, a partir de uma amostra coletada das bases de dados Economática e Standard & Poor’s/Fitch, entre os anos de 2010 e 2014. Resultados: Os indicadores de mercado Risco Soberano e Crescimento do PIB, quando associados aos indicadores contábeis ligados à Qualidade de Ativos, Liquidez, Risco, Capital e Rentabilidade, têm poder preditivo para alterações da classificação de risco dos bancos no Brasil. Em janelas anteriores à alteração do Rating dos bancos, o mercado não precificou as alterações de rating. Tais evidências sugerem que o risco soberano e fatores econômico-sistêmicos podem ser utilizados como sinalizadores de risco em mercados voláteis e de grande incerteza. Contribuições: Diferentemente do que ocorre nos países desenvolvidos, o mercado acionário brasileiro, jovem e pouco representativo da economia, não foi capaz de antecipar alterações no rating dos bancos. A pesquisa antecipa informações aos investidores que auxiliam na decisão de comprar, de manter ou de vender títulos, além de sinalizar que o sistema financeiro está mais suscetível a choques macroeconômicos em economias instáveis.

Abstract Purpose: This work aims to analyze whether market indicators, in complementarity to accounting indicators, have the ability to anticipate changes (upgrades or downgrades) in the assessments of risk rating (rating) of banks in Brazil. Design/methodology/approach: We used information based on the merger of two databases, Economatica and Standard & Poor’s/Fitch, from 2010 to 2014, and linear regressions based on probit models. Findings: Our results show that market-based indicators as Sovereign Risk and GDP growth, together with accounting-based indicators as asset quality, liquidity, risk, capital and profitability, have predictive power for risk rating changes of banks in Brazil. The results still show that the market did not price changes in Brazilian banks’ ratings in windows ending in the event date. Such evidence suggest that Sovereign Risk and economic-systemic factors can be used to proxy for risk in volatile markets with high uncertainty. Originality/value: Unlike in developed countries, the Brazilian stock market, young and not very representative of the economy, was not able to anticipate changes in the banks' rating. This study anticipates information to investors who aid in the decision to buy, hold or sell securities, and signals that the financial system is more susceptible to macroeconomic shocks in unstable economies.

RESUMO: O comprimento do hipocótilo tem-se destacado como potencial descritor da cultura da soja, no entanto, não se tem informação sobre o seu comportamento ao longo de várias épocas de plantio. Diante disto, objetivou-se identificar cultivares de soja com estabilidade e previsibilidade de comportamento quanto ao comprimento do hipocótilo por meio de redes neurais e metodologias tradicionais de adaptabilidade e estabilidade. Analisou-se 16 cultivares de soja em seis épocas de plantio, em condições de casa de vegetação. Em cada época, adotou-se o delineamento em blocos casualizados com quatro repetições, sendo a unidade experimental composta por três plantas e usou-se a média da parcela na análise. Os dados de comprimento de hipocótilo foram analisados por meio da análise de variância e teste de Tukey e, posteriormente, procedeu-se análises por meio do Método Tradicional, Plaisted e Peterson, Wricke, Eberhart e Russell e Redes Neurais Artificiais. Identificou-se efeito significativo (p<0,01 pelo teste F) para Cultivares x Épocas, Épocas e Cultivares. As cultivares BRS810C, BRSMG760SRR, TMG1175RR e BMX Tornado RR apresentaram menores médias, alta estabilidade e adaptabilidade geral quanto ao comprimento do hipocótilo de soja; enquanto que, a cultivar BG4272 apresentou maior média, alta estabilidade e adaptabilidade geral. A identificação de cultivares de soja de comportamento previsível e estável, quanto ao comprimento do hipocótilo, contribui para o Melhoramento da Soja no tocante ao melhor conhecimento do potencial descritor e à possibilidade de incremento do número de descritores.

ABSTRACT: The length of the hypocotyl has been highlighted as a potential descriptor of the soybean crop. However, there is no information available in the published literature about its behavior over several planting times. The present study aimed to identify soybean cultivars with stability and predictability of hypocotyl length behavior through neural networks and traditional adaptability and stability methodologies. We analyzed 16 soybean cultivars in 6 planting seasons under greenhouse conditions. In each season, a randomized block design with 4 replications was adopted. The experimental unit was composed of 3 plants. The plot mean was used in the analysis. Hypocotyl length data were analyzed by analysis of variance and Tukey’s test. Then analyses were carried out using the Traditional Method, Plaisted and Peterson, Wricke, Eberhart and Russell, and Artificial Neural Networks. A significant effect (p<0.01 by the F test) was identified for Cultivars versus Planting Season and Planting Seasons and Cultivars. Cultivars BRS810C, BRSMG760SRR, TMG1175RR, and BMX Tornado RR showed lower averages, high stability, and general adaptability regarding soybean hypocotyl length whereas the cultivar BG4272 presented higher mean, high stability, and general adaptability. Identification of soybean cultivars of predictable and stable behavior as to hypocotyl length contributes to Soybean Improvement as it further our knowledge on the potential descriptor and the possibility of increasing the number of descriptors.

ABSTRACT Background: Dynamic-contrast enhanced (DCE) sequence is used to increase detection of small lesions, based on increased vascularization. However, literature is controversy about the real incremental value of DCE in detection of clinically significant (CS) prostate cancer (PCa), since absence of enhancement does not exclude cancer, and enhancement alone is not definitive for tumor. Purpose: To test the hypothesis that DCE images do not increase CS PCa detection on MRI prior to biopsy, comparing exams without and with contrast sequences. Material and Materials and Methods: All men who come to our institution to perform MRI on a 3T scanner without a prior diagnosis of CS PCa were invited to participate in this study. Reference standard was transrectal prostate US with systematic biopsy and MRI/US fusion biopsy of suspicious areas. Radiologists read the MRI images prospectively and independently (first only sequences without contrast, and subsequently the entire exam) and graded them on 5-points scale of cancer suspicion. Results: 102 patients were included. Overall detection on biopsy showed CS cancer in 43 patients (42.2%), clinically non-significant cancer in 11 (10.8%) and negative results in 48 patients (47%). Positivities for CS PCa ranged from 8.9% to 9.8% for low suspicion and 75.0% to 88.9% for very high suspicion. There was no statistical difference regarding detection of CS PCa (no statistical difference was found when compared accuracies, sensitivities, specificities, PPV and NPV in both types of exams). Inter-reader agreement was 0.59. Conclusion: Exams with and without contrast-enhanced sequences were similar for detection of CS PCa on MRI.

ABSTRACT Purpose: Ultrasound-magnetic resonance imaging (US-MRI) fusion biopsy (FB) improves the detection of clinically significant prostate cancer (PCa). We aimed to compare the Gleason upgrading (GU) rates and the concordance of the Gleason scores in the biopsy versus final pathology after surgery in patients who underwent transrectal ultrasound (TRUS) systematic random biopsies (SRB) versus US-MRI FB for PCa. Materials and Methods: A retrospective analysis of data that were collected prospectively from January 2011 to June 2016 from patients who underwent prostate biopsy and subsequent radical prostatectomy. The study cohort was divided into two groups: US-MRI FB (Group A) and TRUS SRB (Group B). US-MRI FB was performed in patients with a previous MRI with a focal lesion with a Likert score ≥3; otherwise, a TRUS SRB was performed. Results: In total, 73 men underwent US-MRI FB, and 89 underwent TRUS SRB. The GU rate was higher in Group B (31.5% vs. 16.4%; p=0.027). According to the Gleason grade pattern, GU was higher in Group B than in Group A (40.4% vs. 23.3%; p=0.020). Analyses of the Gleason grading patterns showed that Gleason scores 3+4 presented less GU in Group A (24.1% vs. 52.6%; p=0.043). The Bland-Altman plot analysis showed a higher bias in Group B than in Group A (-0.27 [-1.40 to 0.86] vs. −0.01 [-1.42 to 1.39]). In the multivariable logistic regression analysis, the only independent predictor of GU was the use of TRUS SRB (2.64 [1.11 – 6.28]; p=0.024). Conclusions: US-MRI FB appears to be related to a decrease in GU rate and an increase in concordance between biopsy and final pathology compared to TRUS SRB, suggesting that performing US-MRI FB leads to greater accuracy of diagnosis and better treatment decisions.

RESUMO O desenvolvimento das habilidades orais em língua estrangeira enfrenta muitas dificuldades no contexto educacional brasileiro, nas modalidades tanto presencial quanto a distância, o que indica uma demanda por maneiras efetivas de ensinar e aprender habilidades orais em inglês. Abordando uma perspectiva ecológica, esta pesquisa buscou investigar as affordances de tecnologias digitais para desenvolver as habilidades orais em língua inglesa por meio das percepções de estudantes de Letras da Universidade Federal de Minas Gerais que usaram ferramentas e aplicativos da internet para realizar tarefas semanais de uma disciplina on-line. Para o grupo de aprendizes em questão, as tecnologias digitais interativas permitiram o planejamento e a (re)gravação de suas produções orais, assim como a prática da compreensão oral, possibilitando que eles identificassem seus erros e dificuldades.

ABSTRACT Both in face-to-face and distance learning, the development of oral skills in foreign languages faces many difficulties in the Brazilian educational context, which indicates a great demand for effective ways of teaching and learning oral English skills. From an ecological perspective, this study aimed at investigating the affordances of digital technologies for developing oral skills in English through the perceptions of Languages and Literature students of the Federal University of Minas Gerais that used internet tools and apps to do weekly assignments from an online course. For this group of learners, the digital interactive technologies allowed them not only to plan and (re)record their oral production, but also to practice the oral comprehension, being capable of identifying their mistakes and difficulties.
