ABSTRACT Objective: To report outcomes from the largest multicenter series of penile cancer patients undergoing video endoscopic inguinal lymphadenectomy (VEIL). Materials and Methods: Retrospective multicenter analysis. Authors of 21 centers from the Penile Cancer Collaborative Coalition-Latin America (PeC-LA) were included. All centers performed the procedure following the same previously described standardized technique. Inclusion criteria included penile cancer patients with no palpable lymph nodes and intermediate/high-risk disease and those with non-fixed palpable lymph nodes less than 4 cm in diameter. Categorical variables are shown as percentages and frequencies whereas continuous variables as mean and range. Results: From 2006 to 2020, 210 VEIL procedures were performed in 105 patients. Mean age was 58 (45-68) years old. Mean operative time was 90 minutes (60-120). Mean lymph node yield was 10 nodes (6-16). Complication rate was 15.7%, including severe complications in 1.9% of procedures. Lymphatic and skin complications were noted in 8.6 and 4.8% of patients, respectively. Histopathological analysis revealed lymph node involvement in 26.7% of patients with non-palpable nodes. Inguinal recurrence was observed in 2.8% of patients. 10y- overall survival was 74.2% and 10-y cancer specific survival was 84.8%. CSS for pN0, pN1, pN2 and pN3 were 100%, 82.4%, 72.7% and 9.1%, respectively. Conclusion: VEIL seems to offer appropriate long term oncological control with minimal morbidity. In the absence of non-invasive stratification measures such as dynamic sentinel node biopsy, VEIL emerged as the alternative for the management of non-bulky lymph nodes in penile cancer.

RESUMO O objetivo deste estudo foi avaliar o efeito de frequências de irrigação e volumes de substratos sobre a massa de frutos, qualidade de frutos e eficiência do uso da água de melão cantaloupe em ambiente protegido. O estudo foi conduzido na Universidade Federal de Rondonópolis, MT, de fevereiro a agosto de 2021, em delineamento de blocos ao acaso em esquema fatorial 3 × 4 com quatro repetições. Os volumes de substrato utilizados nos vasos plásticos foram de 5, 10 e 15 dm3 e as frequências de irrigação foram uma vez ao dia, duas vezes ao dia, três vezes ao dia e uma vez a cada dois dias. As características avaliadas foram massa de fruto, espessura da polpa, eficiência de uso da água, teor de sólidos solúveis e acidez titulável. As frequências de irrigação de uma e três vezes ao dia apresentaram melhor desempenho para massa de fruto e espessura da polpa. A eficiência do uso da água foi maior para a frequência de três vezes ao dia. Com exceção da acidez titulável, os volumes de substrato de 10 e 15 dm3 apresentaram os maiores desempenhos para todas as variáveis avaliadas. Quanto ao teor de sólidos solúveis os frutos apresentaram níveis que os classificaram como frutos extra, de alta qualidade e indicados para exportação.

ABSTRACT The objective of this study was to evaluate the effect of irrigation frequencies and substrate volumes on fruit mass, fruit quality and water use efficiency of cantaloupe melon in protected environment. The study was conducted at the Federal University of Rondonópolis, MT, Brazil, from February to August 2021, in randomized block design in a 3 × 4 factorial scheme with four replicates. The substrate volumes used in plastic pots were 5, 10 and 15 dm3 and the irrigation frequencies were once a day, twice a day, three times a day and once every other day. The characteristics evaluated were fruit mass, pulp thickness, water use efficiency, soluble solids content, and titratable acidity. The irrigation frequencies of once and three times a day showed the best performance for fruit mass and pulp thickness. The water use efficiency was higher for the frequency of three times a day. With the exception of titratable acidity, the substrate volumes of 10 and 15 dm3 showed the highest performances for all the variables evaluated. As for the soluble solids content, all fruits showed levels that classified them as extra fruits, of high quality and indicated for exportation.

Abstract Wear resistance is a fundamental property which defines the lifetime of cutting tools, but the investigation of wear performance of alternative hard materials for traditional WC-Co composites are recent. The present work evaluated the pin-on-disk wear behavior and mechanical properties, i.e., hardness and fracture toughness of spark plasma sintered Al2O3 matrix composites with additions of 5, 15, 25 or 30%wt of niobium carbide NbC. The wear resistance was observed to increase as a function of the NbC content, even though the hardness reached a plateau at 25%wt NbC. The composite behavior was compared to that of other alumina composite tool materials proving to be a promising material for applications such as ceramic cutting tools. The composition A95N5 presented the best combination of values of wear rate: 8.9 mm3/N.m, hardness equal to (17.36±1.72) GPa and fracture toughness of (3.2±0.6) MPa. m1/2.

Abstract Aims: Movement specific warm-up is a widely accepted practice in the sports environment; however, little is known regarding the ideal intensity of its performance. To verify the effects of adding high-intensity sets to the warm-up on strength, muscular electrical activity, and body temperature in the bench press exercise. Methods: Twelve men (21±1.7 years, 23.9±3.5 kg.m2) were evaluated by a maximal repetition test (1-RM), after which the volunteers performed three procedures: Low-intensity warm-up (LIW), low-intensity warm-up with high-intensity sets (WHI), and no warm-up (CON). Next, they performed maximal isometric voluntary contractions (MIVC) of the chest press to assess the electromyographic activity of the pectoralis major, peak rate of force, development (RFDpeak), and maximum strength (Smax). The skin temperature was evaluated before starting the test. Results: No between-condition differences (p≤0.05) were found for Smax (CON = 320.3±83.8 N; LIW = 300.1±131.6 N, HIW = 327.0±113.9 N; p = 0.689), RFDpeak (CON = 4399±1776 Ns-1; LIW = 3476±1905 Ns-1; HIW = 4715±2184 Ns-1; p = 0.243), skin temperature (CON = 34.0±1.0 °C, LIW = 34.9±0.8 °C, HIW = 34.8±1.1 °C; p = 0.078) or myoelectric activity according to the root mean square index of sternocostal (p = 0.402) and clavicular (p = 0.535) heads, as well as the median frequency data of sternocostal (p = 0.169) and clavicular heads (p = 0.456). Conclusion: In conclusion, the proposed warm-up protocols were not able to modify strength, muscle electrical activity, or skin temperature in the bench press exercise.

Abstract: En | Text: En | PDF: En

The need to increase the product’s shelf life and the growing concern to minimize the use of synthetic products encouraged the researchers to evaluate the antioxidant activity and quantify phenolic compounds as chlorogenic acid, caffeic acid, rutin, quercetin and apigenin through the use of HPLC, in 29 accesses of Capsicum baccatum. Capsicum baccatum var. pendulum is one species of the Capsicum genus widely consumed in Brazil. It is the second largest pepper produced in the world. However, its chemical composition and mainly its extract antioxidant activity have been poorly reported in literature. In order to deepen the study of the access properties relating the antioxidant activity versus content of phenolic compounds. It is suggested that the BRS, 1643a, 1611 and 1613, accession could be used as natural antioxidants in the food industry.

RESUMO Racional: A volumetria por tomografia computadorizada (VTC) é uma ferramenta útil para a previsão do peso do enxerto (PE) para o transplante hepático com doador vivo (TFDV). Poucos estudos examinaram a correlação entre o VTC e PE no parênquima hepático normal. Objetivo: Analisar a correlação entre VTC e PE em uma população adulta de doadores para o TFDV e realização de revisão sistemática dos modelos matemáticos existentes para calcular o peso de enxertos hepáticos parciais. Métodos: Foram revisados retrospectivamente 28 doadores consecutivos submetidos à hepatectomia direita para o TFDV entre janeiro de 2009 a janeiro de 2013. Todos os doadores eram adultos saudáveis com VTC pré-operatório. Os enxertos foram perfundidos com solução de preservação HTK. O volume estimado foi obtido por VTC e estes valores foram comparados com o peso real do enxerto, o qual foi aferido depois da hepatectomia e perfusão do enxerto. Resultados: A mediana do PE real foi de 782,5 g, média de 791,43±136 g, variando de 520-1185 g. A mediana do volume estimado do enxerto foi de 927,5 ml, média de 944,86±200,74 ml e variou de 600-1477 ml. A regressão linear volume estimado do enxerto e PE real foi significativamente linear (PE=0.82 do volume estimado do enxerto, r2=0,98, declive=0,47, desvio-padrão de 0,024 e p<0,0001). Correlação linear de Spearman foi de 0,65, com IC de 95% do 0,45-0,99 (p<0,0001). Conclusão: A regra de "um-para-um" não deve ser empregada em pacientes com parênquima hepático normal. A melhor estimativa do peso do enxerto hepático de doador vivo pode ser alcançado através da multiplicação do VTC por 0,82.

ABSTRACT Background: Computed tomography volumetry (CTV) is a useful tool for predicting graft weights (GW) for living donor liver transplantation (LDLT). Few studies have examined the correlation between CTV and GW in normal liver parenchyma. Aim: To analyze the correlation between CTV and GW in an adult LDLT population and provide a systematic review of the existing mathematical models to calculate partial liver graft weight. Methods: Between January 2009 and January 2013, 28 consecutive donors undergoing right hepatectomy for LDLT were retrospectively reviewed. All grafts were perfused with HTK solution. Estimated graft volume was estimated by CTV and these values were compared to the actual graft weight, which was measured after liver harvesting and perfusion. Results: Median actual GW was 782.5 g, averaged 791.43±136 g and ranged from 520-1185 g. Median estimated graft volume was 927.5 ml, averaged 944.86±200.74 ml and ranged from 600-1477 ml. Linear regression of estimated graft volume and actual GW was significantly linear (GW=0.82 estimated graft volume, r2=0.98, slope=0.47, standard deviation of 0.024 and p<0.0001). Spearman Linear correlation was 0.65 with 95% CI of 0.45 - 0.99 (p<0.0001). Conclusion: The one-to-one rule did not applied in patients with normal liver parenchyma. A better estimation of graft weight could be reached by multiplying estimated graft volume by 0.82.

Resumo A Bacia Hidrográfica Rio do Campo está situada no terceiro planalto paranaense, na porção média entre os rios Ivaí e Piquiri, Sul do Brasil, entre as coordenadas 23° 53’ e 24°10’ de Latitude Sul e 52°15’ e 52°31’ de Longitude Oeste. A bacia ocupa área de 384 Km2, sendo 247 km2 no município de Campo Mourão e 137 km2 no município de Peabiru, no estado do Paraná. O Rio do Campo é um afluente da margem esquerda do Rio Mourão, que deságua no Rio Ivaí. O objetivo deste trabalho foi monitorar a qualidade da água do rio Km 119 e rio do Campo, afluentes do Rio Mourão, com coletas mensais de amostras de água para determinação do pH, temperatura, turbidez, demanda bioquímica de oxigênio, oxigênio dissolvido, coliformes fecais, sólidos totais, nitrogênio total, nitrogênio amoniacal, nitrito, nitrato e fósforo total. Os resultados obtidos foram comparados aos limites estabelecidos na legislação ambiental vigente para poluentes na água e aplicados na determinação do Índice de Qualidade das Águas (IQA) usado pelo Instituto das Águas do Paraná, órgão ambiental fiscalizador. A má qualidade observada nestes rios é preocupante para a região que usufruiu destas águas como principal fonte de abastecimento público. Resultados de matéria orgânica, coliformes totais e fósforo total extrapolaram os padrões estabelecidos na Resolução CONAMA 357/2005 para rio classe 2, especialmente à jusante do rio Km 119 e do Rio do Campo, devido à influência significativa da atividade antrópica urbana pela falta de tratamento terciário e rural pela falta de saneamento básico nesta área. Os resultados do IQA do Rio Km 119 e Rio do Campo indicam que as águas podem ser classificadas com qualidade média em 71% e boa em 29% nos pontos avaliados.

The Campo River basin is located on the third plateau of the Paraná State or trap plateau of Paraná, at the middle portion between the rivers Ivaí and Piquiri, southern Brazil, between the coordinates 23° 53 and 24° 10’ South Latitude and 52° 15’ and 52° 31’ West Longitude. The basin has 384 Km² area, being 247 km2 in the municipality of Campo Mourão and 137 km2 in the municipality of Peabiru, in Paraná State. The Campo River is a left bank tributary of the Mourão River, which flows into the Ivaí River. The objective of this study was to monitor water quality in the Km 119 River and the Campo River, tributaries of the Mourão River, with monthly collection of water samples to determine pH, temperature, turbidity, biochemical oxygen demand, dissolved oxygen, fecal coliforms, total solids, total nitrogen, ammoniacal nitrogen, nitrite, nitrate and total phosphorus. The results obtained were compared with the indices established by the environmental legislation and applied in the determination of the Water Quality Index (WQI) used by the Water Institute of Paraná State, regulating environmental agency. Poor water quality in these rivers presents a worrying scenario for the region, since this river is the main source of water supply for the public system. Results of organic matter, fecal coliforms and total phosphorus were higher than the limits established by Resolution CONAMA 357/2005 to river class 2, specially at downstream of the Km 119 River and the Campo River, due to the significant influence of the urban anthropic activity by the lack of tertiary treatment and also rural by the lack of basic sanitation in this area. Results of WQI of Km 119 River and do Campo River indicated that water quality can be classified as average in 71% and good in 29% of the sites evaluated.

Com o intuito de verificar a qualidade microbiológica de afluentes e efluentes de uma estação de tratamento de esgoto (ETE), um monitoramento de oito meses foi realizado para examinar a presença de coliformes totais e fecais, e de adenovírus (HAdV), enterovírus (EV), rotavírus do genogrupo A (GARV) e torque teno vírus (TTV), em amostras de esgoto tratado da ETE São João/Navegantes, em Porto Alegre-RS, Brasil. Um total de 16 amostras foi coletado, sendo oito de afluente (esgoto bruto, anterior ao tratamento) e oito de efluente (esgoto tratado). Os níveis de coliformes totais e fecais variaram entre 3,6 × 10(4) e 4,4 × 10(7) MPN/100 mL e 2,9 × 10³ e 1,7 × 10(7) MPN/100 mL, respectivamente, tendo sido estes detectados em todas as amostras. No esgoto bruto, foram detectados os genomas virais de HAdV (25%) e GARV (28,6%). A análise das amostras de efluente revelou a presença de fragmentos genômicos de HAdV (50%), EV (37,5%) e TTV (12,5%). Todas as amostras, independentemente do mês analisado, possibilitaram a detecção de pelo menos um gênero viral, exceto no mês de abril. Altas taxas de detecção viral foram observadas em amostras de esgoto tratado (62,5%), sendo que o HAdV foi detectado em 80% dessas amostras de efluente positivas. Os resultados mostram que aprimoramentos no processo de tratamento e monitoramento do esgoto são necessários para reduzir a carga viral e bacteriológica no ambiente do Sul do Brasil. Ao conhecimento dos autores, este é o primeiro estudo de monitoramento de genomas virais em amostras de afluente e efluente de uma ETE localizada em Porto Alegre-Rio Grande do Sul, Brasil.

In order to verify the microbial quality of the influents and effluents of one STP from southern Brazil, an eight-month survey was conducted to examine the presence of total and fecal coliforms and of adenovirus (HAdV), enterovirus (EV), genogroup A rotaviruses (GARV) and Torque teno virus (TTV), in treated effluent samples from São João/Navegantes STP, Porto Alegre (Brazil). A total of 16 samples were collected, eight of influent (raw sewage, prior to treatment), and the other eight of the effluent (post-treatment sewage). Total and fecal coliform levels ranging from 3.6 × 10(4) to 4.4 × 10(7) MPN/100 mL and 2.9 × 10³ to 1.7 × 10(7) MPN/100 mL, were detected in all samples. In raw sewage, HAdV (25%) and GARV (28.6%) viral genomes were detected. The analysis of effluent samples revealed the presence of HAdV (50%), EV (37.5%), and TTV (12.5%) genomic fragments. All samples, regardless of the month analysed, presented detection of a least one virus genus, except for in April. Higher virus detection rates were observed in treated sewage samples (62.5%), and in 80% of them (effluent positive samples) HAdV was detected. Results showed that improvements in sewage monitoring and treatment processes are necessary to reduce the viral and bacterial load on the environment in southern Brazil. To the knowledge of the authors, this is the first study showing the monitoring of viral genomes in influent and effluent samples from a STP located in Porto Alegre (Rio Grande do Sul, Brazil), southern Brazil.
