Conclusion: in adult patients with chronic renal failure, sarcopenia prevailed in subjects with fair and poor quality of life.

Abstract Licania macrophylla is a medicinal plant from the Amazon. It is mainly used in the form of a decoction and has been reported to contain several phenolic compounds. However, the effect of seasonality on the phenolic composition and antioxidant potential of this plant has not been well studied, especially in the Amazon region, an area affected by the rainy and less-rainy seasons. Therefore, we evaluated the seasonality of these aromatic compounds and the antioxidant potential of the extracts from L. macrophylla stem bark. We also determined the correlation between the extraction methods used and precipitation levels during each period for 1 year. The total flavonoid and phenolic content, DPPH-scavenging potential, percentage of phosphomolybdenum complex reduction, and iron-reducing power were quantified. The levels of phenolic compounds were the highest in June, whereas those of flavonoids were the highest in September and October; however, these differences were not significant. The extracts from April, November, and June showed the best results for DPPH scavenging, phosphomolybdenum reduction, and iron reduction power, respectively. Significant differences in the phenolic content and DPPH-scavenging activity were observed between the more- and less-rainy seasons. The total phenolic content was positively correlated with FRAP and DPPH, whereas flavonoid levels were negatively correlated.

Abstract This study’s main highlight to the effect of replacement of milk by different proportions of concentrated whey in the elaboration of ice creams and the characterization of their physicochemical and microstructural properties. Ice creams have high levels of total solids, acidity, and low pH values. All ice creams exhibited Newtonian fluid behaviors while the Power and Casson Law model adequately explained the flow properties. Viscosity and hysteresis area increased as a higher ratio of concentrated whey was added. Ice cream formulations containing a higher proportion of milk showed greater brightness, the ice creams showed a greenish-yellow coloring tendency. The overrun values ranged from 27 to 44%, and ice cream with partial replacement of milk by concentrated whey showed greater resistance to melting. The addition of concentrated whey did not influence the size of the ice crystals, fat globules, and air bubble diameters. However, the higher total solids content influenced the texture of the ice creams, promoting smoother and creamy ice creams. These results highlight the application of concentrated whey on the 50% substitution level, thus being an attractive alternative for the food industry, mainly about the cost-benefit and added value to the product, by enhancing the color, flavor, and texture.

Abstract Freeze concentration process was used to concentrate milk until the third stage of freeze concentration. Thus, two samples of ice creams were manufacture, one with milk and the other with concentrated milk from the first stage of block freeze concentration, and denominated ice cream 1 and ice cream 2, respectively. Both ice creams were characterized according to physicochemical characteristics, overrun, microscopy, melting rate, texture, color, and rheological properties. The use of concentrated milk influenced the physicochemical properties of ice cream 2, promoting an increase in the total solids, protein, carbohydrates, and ashes content. Moreover, it was noted that ice cream 2 had a higher overrun, lower firmness, smaller ice crystals, and tended to color greenish and yellowish, however had a higher melting rate and larger hysteresis area. The models of the Power Law and Casson satisfactorily described the rheological behavior of ice creams, which proved to be a Newtonian fluid.

Resumo O objetivo deste estudo foi identificar membros da família Sarcocystidae em aves silvestres de vida livre naturalmente infectadas e resgatadas no estado de Minas Gerais, Brasil. Coração e cérebro de 44 aves silvestres foram avaliados por bioensaio em camundongos para detecção de T. gondii e extração de DNA para Nested-PCR do gene 18S do DNA ribossomal de membros da família Sarcocystidae. As amostras positivas foram sequenciadas, analisadas, editadas e comparadas com sequências depositadas no GenBank. Toxoplasma gondii foi isolado de seis (13,6%) das 44 aves. DNA de T. gondii foi identificado em 10/44 (22,7%) das 44 aves. As sequências amplificadas exibiram 100% de similaridade com o DNA da cepa ME49 de T. gondii. DNA de Sarcocystis (99% de similaridade) foi identificado em 5/44 (11,4%) das 44 aves. T. gondii e Sarcocystis spp. são encontrados, comumente, em aves silvestres no estado de Minas Gerais, Brasil.

Abstract This study aimed to identify members of the Sarcocystidae family in naturally infected wild birds at a rescue center in the state of Minas Gerais, southeastern Brazil. The heart and brain of 44 wild birds were evaluated by bioassay in mice to detect T. gondii, and extracted DNA was used for nested PCR of the 18S ribosomal DNA gene to detect members of the Sarcocystidae family. The positive samples were sequenced, assembled, edited and compared with sequences deposited in GenBank. Toxoplasma gondii was isolated from six (13.6%) out of 44 birds. Toxoplasma gondii DNA was identified in 10/44 (22.7%) of the birds. The amplified sequences exhibited 100% similarity with the DNA of the ME49 strain of T. gondii. Sarcocystis DNA (99% similarity) was identified in 5/44 (11.4%) of the birds. T. gondii and Sarcocystis spp. are common in wild birds in Minas Gerais, Brazil.

RESUMO Objetivo Comparar a força de fixação dos parafusos para artrodese subtalar. Métodos Oito pares de pés de cadáveres frescos foram submetidos à artrodese da articulação subtalar com dois parafusos canulados de 7,3mm. A randomização foi usada para atribuir a orientação do parafuso, de modo que um pé em cada par foi designado com orientação de dorsal para plantar (Grupo DP), e o outro pé com orientação de plantar para dorsal (Grupo PD). Técnica cirúrgica padrão com radioscopia foi usada para os procedimentos. Após a fixação, cada amostra foi testada até a falha com um dispositivo Bionix®858 MTS, aplicando força axial descendente a uma distância para criar torque. O torque de falha foi comparado entre os Grupos DP e PD, usando o teste t de Student, com p=0,05 usado para determinar significância estatística. Resultados A análise estatística demonstrou que a média do torque até a falha favoreceu ligeiramente o Grupo DP (37,3Nm) em relação ao PD (32,2Nm). No entanto, a diferença entre os dois grupos não foi estatisticamente significativa (p=0,55). Conclusão Na artrodese subtalar, não há diferença significativa na força de compressão entre as orientações dos parafusos dorsal-plantar e plantar-dorsal. A abordagem escolhida pelo cirurgião deve ser baseada em outros fatores, sem preocupação com a força biomecânica da orientação dos parafusos.

ABSTRACT Objective To compare screw fixation strength for subtalar arthrodesis. Methods Eight matched pairs of cadaver feet underwent subtalar joint arthrodesis with two 7.3mm cannulated screws. Randomization was used to assign screw orientation, such that one foot in each pair was assigned dorsal to plantar screw orientation (DP Group), and the other foot, plantar to dorsal orientation (PD Group). Standard surgical technique with fluoroscopy was used for each approach. Following fixation, each specimen was loaded to failure with a Bionix ® 858 MTS device, applying a downward axial force at a distance to create torque. Torque to failure was compared between DP and PD Groups using Student’s t test, with p=0.05 used to determine statistical significance. Results Statistical analysis demonstrated that the mean torque to failure slightly favored the DP Group (37.3Nm) to the PD Group (32.2Nm). However, the difference between the two groups was not statistically significant (p=0.55). Conclusion In subtalar arthrodesis, there is no significant difference in construct strength between dorsal-to-plantar and plantar-to-dorsal screw orientation. The approach chosen by the surgeon should be based on factors other than the biomechanical strength of the screw orientation.

Abstract The need to optimize the management and the use of the excreta is due to the fact that animal species do not take advantage of 100 % of the nutrients consumed of the food, the excrement being a potential source of these. The amount and quality of excretion depends on factors such as food, animal species, production status, health status and type of facilities. Integrated models for waste management should consider the revaluation of these as raw material, in order to develop technologies that enable the recovery of nutrients. Pig waste silage, compost, vermicompost, and anaerobic digestion systems are part of these schemes. On the other hand, the importance of bioremediation lies in the use of the metabolic potential of microorganisms to transform organic pollutants, and can be used to clean contaminated spaces or water. The technological adoption strategy is designed and started by establishing the characteristics of the material to be treated, its conditioning and the conditions of operation of the process, to select the criteria and methods for its scaling in any production system.

Resumen La optimización del manejo y utilización de las excretas, se debe a que las especies animales no aprovechan el 100 % de los nutrientes consumidos del alimento, siendo la excreta una fuente potencial de estos. La cantidad y calidad de la excreta depende de factores como el alimento, especie animal, etapa productiva, estado de salud y tipo de instalaciones. Los modelos integrados para manejo de residuos pecuarios, deben considerar la revalorización de estos como materia prima, con objeto de desarrollar tecnologías que habiliten la recuperación de nutrientes. El ensilaje de cerdaza, la composta, vermicomposta y los sistemas de digestión anaerobia forman parte de estos esquemas. Por otro lado, la importancia de la bio-remediación radica en la utilización del potencial metabólico de los microorganismos para transformar los contaminantes orgánicos, pudiéndose utilizar para limpiar espacios o aguas contaminadas. La estrategia de adopción tecnológica se diseña y se inicia a través de establecer las características del material a tratar, su acondicionamiento y las condiciones de operación del proceso, para seleccionar los criterios y métodos para su escalamiento en cualquier sistema de producción.

SUMMARY: Laparoscopic cholecystectomy is the treatment indicated for cholelithiasis, however the procedure is not free of complications or concomitant morbidity. It is possible that, due to collateral ductal lesions, bleeding occurs with the possibility of surgery conversion and undesirable results. For a correct approach to the region it is essential to identify the cystohepatic trigone (CHT) and its components, as well as the ligation and section of the cystic artery (AC). Knowing the high variability of CA, the aim of this work was to identify the number, origin, path and relationship of CA with the CHT and its variations using angiotomography by means of a 64-slice detector tomograph in the preoperative period of 30 female patients, between 24 and 54 years old, with clinically diagnosed cholelithiasis and by echo sonography. The AC in 76.67 % was unique and was within the CHT, in 16.67 % it was unique and was observed outside the CHT. In 6.67 %, two ACs were observed, one inside and one outside the TCH. In 66.67 % of cases, CA originated normally from the right hepatic artery. The traceability of AC was 53.3 % moderately visible and 46.7 % excellent traceability. In conclusion, the identification of AC and its anatomical variations can be determined in the preoperative period and can be useful to improve the surgical plan in patients with cholelithiasis, providing information on the procedure, optimizing it and reducing the risks of possible bleeding related complications.

RESUMEN: La colecistectomía laparoscópica es el tratamiento indicado en la colelitiasis, sin embargo el procedimiento no está exento de complicaciones o morbilidad concomitante. Es posible que, debido a lesiones ductales colaterales, ocurra sangrado con posibilidad de conversión de la cirugía e indeseables resultados. Para un correcto abordaje de la región se hace fundamental la identificación del trígono cistohepático (TCH) y sus componentes, a su vez de la ligadura y sección de la arteria cística (AC). Conociendo la elevada variabilidad de la AC, el objetivo de este trabajo consistió en identificar el número, origen, trayecto y relación de la AC con el TCH y sus variaciones, utilizando angiotomografía por medio de un tomógrafo detector de 64 cortes, en el preoperatorio de 30 pacientes de sexo femenino, entre 24 y 54 años de edad, con colelitiasis diagnosticadas clínicamente y por ecosonografía. La AC en el 76,67 % era única y se encontraba dentro del TCH, en el 16,67 % era única y se observó fuera del TCH. En el 6,67 % se observaron dos AC, una dentro y otra fuera del TCH. En el 66,67 % de los casos la AC se originaba de manera normal de la arteria hepática derecha. La trazabilidad de la AC fue en el 53,3 % medianamente visible y en el 46,7 % de trazabilidad excelente. En conclusión, la identificación de la AC y sus variaciones anatómicas se puede determinar en el preoperatorio y puede ser útil para mejorar el plan quirúrgico en pacientes con colelitiasis, brindando información al procedimiento, optimizarlo y disminuir los riesgos de eventuales complicaciones relacionados con sangrado.

Resumo Objetivou-se avaliar a capacidade para o trabalho de mototaxistas e sua associação com fatores sociodemográficos, laborais e qualidade de vida. Estudo transversal, realizado com 392 mototaxistas, utilizando-se formulário com dados sociodemográficos, laborais, Índice de Capacidade de Trabalho e o WHOQOL-bref. Empregou-se análise descritiva e inferencial. A prevalência de capacidade para o trabalho moderada/boa foi de 51%. Mototaxistas com 40 ou mais anos tiveram aumento de 31% na capacidade baixa para o trabalho (RP: 1,31; IC 95%: 1,07; 1,61) comparados aos mais jovens. Mototaxistas de 21 a 29 e de 30 a 39 anos apresentaram maiores medianas para absenteísmo (p = 0,023) e prognóstico próprio sobre a capacidade de trabalho no futuro (p < 0,001). Houve maior proporção para doenças diagnosticadas entre aqueles com cinco anos ou mais na profissão (p = 0,003) e para prognóstico próprio naqueles com cinco anos ou menos (p < 0,001). Mototaxistas com capacidade moderada/boa apresentaram melhor percepção de qualidade de vida no domínio físico (p < 0,001). A capacidade baixa para o trabalho de mototaxistas foi associada à maior exposição aos fatores nocivos que afetam sua qualidade de vida e força de trabalho. É necessário priorizar políticas públicas e ações educativas para minimizar essa exposição.

Abstract This study evaluated the work capacity of motorcycle taxi drivers and its association with sociodemographic and work and quality of life factors. This is a cross-sectional study realized with 392 motorcycle taxi drivers that used a form containing demographic and labor data, Work Capacity Index, the WHOQOL-bref. We employed a descriptive and inferential analysis. The moderate/good prevalence work capacity was 51%. Motorcycle taxi drivers aged 40 years and over recorded a 31% increase in low work capacity (PR: 1.31; 95% CI: 1.07; 1.61) compared to younger workers. Motorcycle taxi drivers aged 21-29 and 30-39 years evidenced a higher median for absenteeism (p = 0.023) and self-prognosis regarding future work capacity (p < 0.001). A greater proportion of diseases diagnosed among those with five or more years of service (p = 0.003) and of self-prognosis in those with five years or less of service (p < 0.001) was observed. Motorcycle taxi drivers with moderate/good capacity showed better perception of quality of life in the physical realm (p < 0.001). Work capacity of motorcycle taxi drivers was associated with higher exposure to noxious factors that affect their quality of life and work force. Priority public policies and educational actions are required to minimize this exposure.

RESUMO O texto segue a trajetória da produção de F. Weffort sobre o chamado “populismo” e mostra seus efeitos no debate dos “movimentos sociais urbanos” e também dos “novos personagens em cena” , defendendo uma história intelectual centrada em ideias e nas tensões entre intelectualidade e expectativas políticas. A observação de inflexões e continuidades na tese populista permite chegar a dois resultados. A miríade de conceitos que marcou, em parte, a gênese da discussão brasileira sobre movimentos sociais nasce como crítica e adesão à herança weffortiana. Além disso, o artigo mostra que os novos conceitos não se gestam em algo como um “campo acadêmico”, e sim nascem de inspirações e influências daquele conjunto de intelectuais e das apostas por eles forjadas em seus núcleos na sociedade civil (o Cedec, no caso) ou nas relações com outros atores civis e partidários.

ABSTRACT The text follows the trajectory of F. Weffort’s production of so-called “populism” and shows its effects in the debate of “urban social movements” (JA Moisés) and also of the “new characters on the scene” (MC Paoli and E. Sader), defending an intellectual history centered on ideas and tensions between intellectuality and political expectations. The observation of inflections and continuities in the populist thesis leads to two results. The myriad concepts that marked, in part, the genesis of the Brazilian discussion of social movements are born as criticism and adherence to the Weffortian heritage. Moreover, the article also shows that the new concepts are not created in an “academic field”, but are born of the inspirations and influences of that group of intellectuals and the bets they forge in their nuclei in civil society or in relations with other civil and partisan actors.

ABSTRACT Objective: Determine the presence of anterior chamber bacterial contamination during cataract surgery. Methods: A cross-sectional case-series study was conducted of patients undergoing cataract surgery at the Ocular Microsurgery Service of Ramón Pando Ferrer Cuban Institute of Ophthalmology from January 2015 to December 2016. Personal ocular and systemic pathological antecedents, associated risk factors and perioperative complications, were related to the presence of anterior chamber bacterial contamination at the end of surgery. Patients were randomly selected in the operating room. The sample was composed of 200 patients, who were divided into three groups according to the surgeons' experience. Results: At the start of the surgical procedure, 100 % of the cultures were negative, whereas at the end 3 % bacterial growth was detected. Gram-positive germs were the most common (66.6 %), with Staphylococcus epidermidis isolated in 50 % of the cases. No significant relationship was found between personal ocular or systemic pathological antecedents and associated risk factors. Posterior capsule rupture was the most frequent intraoperative complication, with 4.7 % bacterial growth detected. Conclusion: Low frequency of anterior chamber contamination was detected at the end of cataract surgery, and the germs commonly found are related to the ocular surface microbiota.

RESUMEN Objetivo: Determinar la existencia de contaminación bacteriana en cámara anterior durante la cirugía de catarata. Métodos: Se realizó un estudio transversal de serie de casos, en el cual participaron los pacientes sometidos a cirugía de catarata en el Servicio de Microcirugía Ocular del Instituto Cubano de Oftalmología “Ramón Pando Ferrer”, en el período comprendido de enero del año 2015 a diciembre 2016. Se relacionaron los antecedentes patológicos personales oculares y sistémicos, los factores de riesgo asociados y las complicaciones transoperatorias con la presencia de bacterias en la cámara anterior al final de la cirugía. Los pacientes fueron seleccionados aleatoriamente en el salón de cirugía. La muestra quedó constituida por 200 pacientes y divididos en tres grupos dependiendo de la experiencia de los cirujanos. Resultados: Al inicio del proceder quirúrgico, el 100 % de los cultivos fueron negativos, mientras que al final de la cirugía se detectó crecimiento bacteriano en el 3 %. Los gérmenes Gram positivos fueron los de mayor frecuencia (66,6 %) donde el Staphylococcus epidermidis se aisló en un 50 % de los casos. No existió relación significativa entre antecedentes patológicos personales oculares, sistémicos y los factores de riesgo asociados. La ruptura de la cápsula posterior fue la complicación transoperatoria más frecuente y al 4,7 % se le detectó crecimiento bacteriano. Conclusión: Se detecta una baja frecuencia de contaminación de la cámara anterior al final de la cirugía de catarata y los gérmenes comúnmente encontrados están relacionados con la microbiota de la superficie ocular.

ABSTRACT Swine production generates every day a large amount of residues, including nutrients and microorganisms, which potentially contribute to contamination of air, water and soil, and generation of unpleasant odors. Many strategies have been developed in order to mitigate the contaminant effect of swine manure and to take advantage of its nutrients and beneficial compounds; silage is an example of these, and consists in swine manure fermentation mainly under anaerobic conditions. The aim of this study was to assess the effect of applying a process of silage to swine manure added with two different sources of carbohydrates and two different sources of lactic-acid bacteria, under the reduction of different microbiological indicators. Through the process, it was observed the reduction of pH levels (until reaching 4.6) and microbial content, mainly for coliforms (reduction greater than 5 log), molds and yeasts, and total elimination of enterococci. On the other hand, significant decline was not reported for the lactic-acid bacteria content, main responsible of fermentation process. Best results were observed through using sorghum as a source of carbohydrates and cheese whey as a source of lactic-acid bacteria, for both, decrease of pH and reduction of some microbiological indicators, including bacteria that produce sulfuric acid. Therefore, silage process, applied to swine manure, induces the decrease of pH for action of lactic-acid bacteria until limit the survival of bacteria associated with fecal contamination, making of swine a transformed and microbiologically safe residue for its handling and subsequent use.

RESUMEN La actividad porcina genera diariamente una gran cantidad de residuos conformados por nutrientes y microorganismos que potencialmente contribuyen a la contaminación de agua, aire y suelos, y la subsecuente generación de olores desagradables. Diversas estrategias se han desarrollado para mitigar el efecto contaminante de las excretas porcinas y aprovechar sus nutrientes; tal es el caso del ensilaje, que consiste en la fermentación de las excretas. En este estudio se evaluó el efecto del ensilaje del estiércol porcino adicionado con dos fuentes diferentes de carbohidratos y dos fuentes de bacterias ácido lácticas, sobre la reducción de diferentes grupos de microorganismos. Durante el proceso se observó la disminución del pH (hasta 4.6) y la carga microbiana, sobre todo para organismos coliformes (reducción mayor a 5 logaritmos) y hongos y levaduras, así como la eliminación total del grupo de enterococos; mientras que el contenido de bacterias ácido lácticas, principales responsables de la fermentación, permaneció constante. Los mejores resultados se observaron mediante el uso de sorgo como fuente de carbohidratos en combinación con suero de leche, subproducto de la elaboración de queso, como fuente de bacterias ácido lácticas, tanto en disminución del pH como en la reducción de algunos indicadores microbiológicos, incluidas las bacterias productoras de ácido sulfhídrico. Mediante el ensilaje del estiércol porcino se favorece la disminución del pH por acción de las bacterias ácido lácticas a niveles que limitan la sobrevivencia de microorganismos asociados a contaminación fecal, y lo transforman en un producto seguro, desde la perspectiva microbiológica, para su manejo y posible aprovechamiento subsecuente.

RESUMO Introdução: Descrita em 1983 e de sólida aplicação clínica, o impacto da Microcirurgia Endoscópica Transanal sobre a função anorretal permanece pouco conhecido. Os objetivos do presente estudo foram avaliar o impacto da Microcirurgia Endoscópica Transanal na função anorretal conforme avaliações clínica (Wexner score) e funcional (manometria anorretal) antes e após a cirurgia. Método: Prospectivamente, 23 pacientes consecutivos com lesões retais foram operados com o uso do equipamento TEO® (Karl Storz, Tuttlingen, Alemanha). Para todos os pacientes, o valor do escore de Wexner foi obtido antes e após a cirurgia (7, 30 e 90 dias) e a eletromanometria anorretal foi realizada antes da cirurgia e também no pós-operatório (30 e 90 dias). Resultados: Quatorze pacientes eram homens. A idade média foi 53,7 (24-81) anos. A distância média da lesão à linha pectínea foi de 7 (2-15) cm. A histopatológica revelou adenoma em 14 (61%), tumor neuroendócrino em 5 (21,7%); carcinoma invasivo em 3 (13%) e pólipo hiperplásico em 1 (4,3%) caso. A duração média do seguimento pós-operatório foi de 5 (3-7) meses. O escore de Wexner foi significativamente menor aos 30 dias em comparação com 7 dias (Wilcoxon; p = 0,03). A capacidade retal foi significativamente menor aos 30 dias após a cirurgia e recuperada aos 90 dias após a cirurgia (ANOVA; p = 0,04). Conclusões: Após Microcirurgia Endoscópica Transanal, um impacto modesto na função anorretal pode ser observado. O comprometimento transitório resulta de perda de capacidade retal e não por comprometimento dos esfíncteres anais cessando completamente 90 dias após a cirurgia.

ABSTRACT Introduction: Described in 1983 and with a stable clinical application, the impact of Transanal Endoscopic Microsurgery on anorectal function remains unknown. The objectives of the present study were to evaluate the impact of Transanal Endoscopic Microsurgery on anorectal function according to clinical (Wexner score) and functional (anorectal manometry) evaluations before and after surgery. Method: Prospectively, 23 consecutive patients with rectal lesions were operated using TEO® equipment (Karl Storz, Tuttlingen, Germany). For all patients, the value of Wexner score was obtained before and after surgery (7, 30 and 90 days) and anorectal electromanometry was performed before surgery, and also postoperatively (30 and 90 days). Results: Fourteen patients were men. The mean age was 53.7 (24-81) years. The mean distance from the lesion to the pectineal line was 7 (2-15) cm. The histopathologic analysis revealed adenoma in 14 (61%); neuroendocrine tumor in 5 (21.7%); invasive carcinoma in 3 (13%); and hyperplastic polyp in 1 (4.3%) case. The mean duration of postoperative follow-up was 5 (3-7) months. Wexner score was significantly lower at 30 days compared to 7 days (Wilcoxon; p = 0.03). Rectal capacity was significantly lower 30 days after surgery and recovered at 90 days of surgery (ANOVA; p = 0.04). Conclusions: After Transanal Endoscopic Microsurgery, a modest impact on anorectal function can be observed. The transient impairment results from loss of rectal capacity and not from impairment of the anal sphincters, being completely resolved 90 days after surgery.
