ABSTRACT Introduction: colonoscopy is the best method for detecting polyps, with a reduction in colorectal cancer mortality of 29% and reaching 47% for distal tumors. However, it fails to demonstrate a significant reduction in proximal colon cancer mortality, and is the most common segment with interval neoplasm. The present study aimed to evaluate the impact on detection of polyps of a second sequential evaluation of cecum and ascending colon, with or without the use of indigo carmine chromoendoscopy. Methods: prospective, non-randomized clinical trial. Patients were divided into two groups. The first (G1) underwent a routine colonoscopy, followed by a second endoscopy assessment of ascending colon and cecum. The second group (G2) underwent a routine colonoscopy, followed by a second assessment of the ascending colon and cecum with indigo carmine chromoendoscopy. Results: In total, 203 patients were analyzed, 101 in the G1 and 102 in the G2. Newer polyps were identified in both groups after the second assessment with a significantly higher number of polyps detected in the patients in the G2 (p=0.0001). The number of patients who had at least one polyp in the two endoscopic assessments was significantly higher in the G2 (53 or 52% vs 27 or 26.7%, p=0.0002). In the second endoscopic assessment, the number of polyps found was also significantly higher in the G2 (50 or 76.9%) compared to the G1 (15 or 23.1%), p<0.0001. Conclusions: the second assessment with dye-based chromoendoscopy increases the detection of polyps in the ascending colon and cecum.

RESUMO Introdução: a colonoscopia é o melhor método para detecção de pólipos, com redução da mortalidade por câncer colorretal de 29% e chegando até 47% para tumores distais. No entanto, existe falha em demonstrar redução significativa na mortalidade no cólon proximal sendo o segmento mais comum de neoplasia de intervalo. O presente estudo avaliou o impacto na detecção de pólipos em uma segunda avaliação sequencial do ceco e cólon ascendente, com ou sem o uso de cromoendoscopia com Indigo carmim. Métodos: estudo prospectivo, não randomizado. Os pacientes foram divididos em dois grupos. O primeiro (G1) foi submetido à colonoscopia de rotina, seguida de segunda avaliação endoscópica do cólon ascendente e ceco. O segundo grupo (G2) foi submetido à colonoscopia de rotina, seguida de segunda avaliação do cólon ascendente e ceco com cromoendoscopia com índigo carmim. Resultados: no total, foram analisados 203 pacientes, sendo 101 do G1 e 102 do G2. Novos pólipos foram identificados em ambos os grupos após a segunda avaliação com número significativamente maior de pólipos detectados nos pacientes do G2 (p=0,0001). O número de pacientes que apresentaram pelo menos um pólipo nas duas avaliações endoscópicas foi significativamente maior no G2 (53 ou 52% vs 27 ou 26,7%, p=0,0002). Na segunda avaliação endoscópica, o número de pólipos encontrados também foi significativamente maior no G2 (50 ou 76,9%) em relação ao G1 (15 ou 23,1%), p<0,000. Conclusão: a segunda avaliação com cromoendoscopia com índigo carmim aumenta a detecção de pólipos no cólon ascendente e no ceco.

Abstract We present an unusual case of a 67-year-old woman with an incidental finding of a cardiac mass on a chest computed tomography. Coronary angiotomography confirmed the diagnosis of right coronary artery aneurysm, with 5.7×5.7 cm. The patient underwent aneurysm resection and coronary bypass surgery, with subsequent histologic study suggestive of arteritis sequelae. Giant coronary artery aneurysms have a high risk of complications and aneurysm exclusion must be beneficial. This is a rare condition that can also be part of a systemic inflammatory disease.

Abstract The objective was to develop and characterize biodegradable films with antimicrobial and antioxidant action, using poly(butylene adipate-co-terephthalate) (PBAT) incorporated with OEO - essential oil (Origanum vulgare). The degradation temperature of the OEO increased after incorporation into the PBAT matrix, however, the degradation of the matrix did not undergo considerable changes. The films showed increase in elongation and modulus of elasticity with presence of OEO, however, it reduced the maximum tension. The permeability of the films was reduced with OEO presence. The spectra (FTIR) showed the presence of the functional groups attributed to the bioactive compounds (Carvacrol) of OEO. The films presented high antioxidant activity and effective antimicrobial action, reducing Staphylococcus aureus in 53 days and psychrotrophic microorganisms in up to 28 days of storage. The films showed to be efficient with antioxidant activity and antimicrobial action with indication to be used as packaging of sliced mozzarella cheese.

Resumo O objetivo do estudo foi avaliar composição química, perfil fermentativo, população de microrganismos e recuperação de matéria seca (RMS) de silagem de cana-de-açúcar contendo níveis crescentes (0, 25, 50 e 75%, na base da matéria natural) de amendoim forrageiro (Arachis pintoi cv. Belmonte), tratadas ou não com Lactobacillus buchneri. Usou-se o esquema fatorial 4×2, no delineamento inteiramente casualizado, com três repetições. Verificou-se efeito de interação níveis de amendoim forrageiro e inoculante para teores de matéria seca, proteína bruta, fibra em detergente neutro e ácido, ácidos orgânicos e etanol, população de bactérias láticas e leveduras, perdas por gases e por efluente e RMS. Houve efeito de níveis de amendoim forrageiro no teor de hemicelulose, nitrogênio insolúvel em detergente ácido, pH e nitrogênio amoniacal. Verificou-se que o aumento de níveis de amendoim forrageiro incrementou teor de proteína e diminuiu teor de fibra, além de reduzir a produção de etanol e de efluente. Recomenda-se inclusão de 40% a 75% de amendoim forrageiro na ensilagem de cana-de-açúcar para melhorar a composição química e o perfil de fermentação. A inoculação com L. buchneri associada ao amendoim forrageiro aumenta a concentração de ácidos antifúngicos na silagem e decresce a população de leveduras e a produção de etanol.

Abstract There is evidence for the beneficial effects of forage peanut on the nutritive value and fermentation profile of silages; however, its effects on sugarcane silage have not been determined. The objective of the study was to evaluate the chemical composition, fermentation profile, microbial composition, and dry matter recovery (DMR) of sugarcane silage containing various amounts of forage peanut (Arachis pintoi cv. Belmonte) (0%, 25%, 50%, and 75% on a fresh matter basis), treated or untreated with Lactobacillus buchneri. A completely randomized 4 × 2 factorial design was used with three replications. The interaction between forage peanut levels and inoculant influenced the concentrations of dry matter, crude protein, neutral detergent fiber and acid detergent fiber, organic acids and ethanol, populations of lactic acid bacteria and yeast, gas and effluent losses, and DMR. Forage peanut levels had effects on dry matter, hemicellulose, acid detergent insoluble nitrogen, pH, and ammonia nitrogen. Increasing proportions of forage peanut increased the protein content and decreased the fiber content in the silage, while also reducing the production of ethanol and effluent. We recommend the inclusion of 40%–75% forage peanut in the sugarcane ensilage to improve the chemical composition and fermentation profile. Furthermore, inoculation with L. buchneri associated with forage peanut increases the concentration of antifungal acids in the silage and decreases the yeast population and ethanol production.

A series of tetrakis-β-diketonate Q+[Ln(β-dik)4]–, where Ln = GdIII or EuIII, Q = ammonium cations and β-dik = tta (2-thenoyltrifluoracetone) or bmdm (1-(4-tert-butylphenyl)-3-(4-methoxyphenyl)-1,3-propanedione) have been synthesized and characterized. The environment surrounding the EuIII ion depends on the lateral groups of the ligand and on the alkyl chains of the counter ion Q. The shortest lifetime (τ) = 0.29 ms, and lowest quantum efficiencies (η) = 24%, were obtained for (N(C12H25)2(CH3)2)+[Eu(bmdm)4]–, while (N(C4H9)4)+[Eu(bmdm)4]– has the longest τ = 1.04 ms and η = 90%. The Judd-Ofelt intensity parameters (Ω2 and Ω4) strongly changes for tta series pointing to stronger ion-dipole interactions between the –CF3 group with the ammonium cations. The agreement between the experimental results of photoluminescence and theoretical data suggests that the geometries optimized by the Sparkle model are correct. These results point to potential candidates for building up Langmuir-Blodgett (LB) luminescent films, since it is possible to maximize the intermolecular interactions and the photoluminescent properties of tetrakis LnIII complexes.

O presente artigo descreve o caso de uma paciente de 54 anos com perda de peso, dor abdominal e ascite. A ultrassonografia mostrou espessamento endometrial, e a histeroscopia por vídeo revelou uma cavidade uterina com formações que apresentavam aspecto de algodão cobrindo toda a superfície endometrial e os óstios tubários. Uma avaliação anatomopatológica diagnosticou tuberculose endometrial. O tratamento foi com esquema terapêutico padronizado (etambutol, isoniazida, pirazinamida e rifampicina), e a paciente evoluiu com melhora clínica e cavidade uterina normal na histeroscopia. Considerando a falta de achados histeroscópicos patognomônicos do distúrbio, é importante divulgar as imagens do caso.

Abstract Endometrial tuberculosis is a rare diagnosis in the postmenopausal period, and it can mimic a carcinoma. The present article describes the case of a 54-year-old female patient with weight loss, abdominal pain, and ascites. An ultrasonography showed endometrial thickening, and a video hysteroscopy revealed a uterine cavity with formations with cotton aspect covering the entire endometrial surface and the tubal ostia. An anatomopathological evaluation diagnosed endometrial tuberculosis. The treatment was with a standardized therapeutic scheme (ethambutol, isoniazid, pyrazinamide and rifampicin), and the patient evolved with clinical improvement and normal uterine cavity at hysteroscopy. Considering the lack of pathognomonic hysteroscopic findings of the disorder, it is important to disclose the images of the case.

Objetivo: Determinar la composición, parámetros químicos de fermentación, y calidad del ensilaje elaborado a partir de residuos procedentes de la producción de palmito de Palma Real. Métodos: Tres tipos de ensilaje hechos con los residuos generados a partir de la producción de palmito fueron evaluados: 1) ensilaje de hojas, 2) ensilaje de vainas, y 3) ensilaje compuesto (hojas + vainas). Los residuos tratados fueron empacados en silos experimentales y distribuidos en un diseño completamente al azar con 10 repeticiones. Las medias fueron comparadas mediante la prueba de Tukey, con un nivel de significancia del 5%. Resultados: El ensilaje de hojas mostró el pH más alto (p<0,05) y el nivel más bajo de nitrógeno amoniacal (p<0,05) en comparación con los otros ensilajes. No se observaron diferencias (p>0,05) en los ácidos láctico y butírico, mientras que el ácido acético fue mayor en el ensilaje de vainas y en el compuesto en relación con el otro ensilaje. La materia seca (MS) y el contenido de proteína cruda (PC) fueron mayores (p<0,05) en el ensilaje de hojas. Los contenidos de fibra detergente neutra fueron mayores (p<0,05) en los ensilajes de vainas, seguido por los ensilajes de hojas y compuesto, respectivamente. El contenido de lignina fue más alto (p<0,05) en el ensilaje de vainas. Conclusiones: Según los parámetros fermentativos, los residuos de la producción de palmito de Palma Real tienen potencial para la producción de ensilaje. Sin embargo, se deben considerar las diferencias en la composición de los ensilajes al momento de alimentar rumiantes.

Abstract Background: Production of heart-of-palm from Alexander palm tree generates a waste that could be used as silage for feeding ruminants. Objective: To evaluate the chemical composition, fermentation parameters, and quality of silage made from waste of heart-of-palm production using Alexander palm. Methods: Three types of silage made from waste of heart-of-palm production were evaluated: 1) leaf silage, 2) sheath silage, and 3) compound (leaf + sheath) silage. The processed waste was packed in experimental silos and distributed in a completely randomized design with 10 replications. Means were compared pairwise using Tukey’s test at the 5% significance level. Results: Leaf silage had the highest pH (p<0.05) and the lowest ammonia nitrogen (p<0.05) in relation to the other silages. No difference was observed (p>0.05) for lactic and butyric acids, whereas acetic acid was higher (p<0.05) in the sheath and compound silages. Dry matter and crude protein contents were the highest (p<0.05) in leaf silage. Neutral detergent fiber was higher (p<0.05) in sheath silage, followed by leaf and compound silages, respectively. The highest lignin content (p<0.05) was observed in sheath silage. Conclusions: Based on the fermentative parameters, waste from heart-of-palm from Alexander palm tree has potential for silage production. However, differences in silage composition at the time of feeding ruminants should be considered.

No entanto, as diferenças na composição das silagens devem ser consideradas quando oferecidas para animais ruminantes.

Abstract: The genus Dermocystidium is very comprehensive in the host and site of infection, however this is the first report of the occurrence of Dermocystidium sp. in the gills of Nile tilapia. This study was carried out in a fish farming located in the state of Santa Catarina, Brazil. No mortalities were reported in the facility studied and the animals were clinically healthy. During the histopathological analysis of the gills, 8.33% of the fish presented spores of Dermocystidium sp. in the gill tissue. The spores reported herein had a mean length and width of 6.206 x 5.233 μm and a refractile body diameter of 1.965 μm and were studied by histopathology and Transmission Electron Microscopy. This study highlights the importance of a new branchial pathogen in farmed tilapia, as well as to its pathogenic potential, considering the outbreaks of mortalities associated with other fish species.

ABSTRACT This study aimed to characterize the metazoan parasitic fauna associated with freshwater farmed ornamental fish in Southern Brazil. Between July 2014 and January 2015, a total of 423 fish belonging to nine species were examined: Pterophylum scalare, Betta splendens, two varieties of Carassius auratus, Danio rerio, Xiphophorus helleri, two varieties of Xiphophorus maculatus, Poecilia sphenops, Tanichthys albonubes and Puntius sachsii. In each fish collection, the water quality parameters were measured. Specimens were obtained from three ornamental fish farms located in three micro-regions in the State of Santa Catarina (Araquari, Biguaçu and Camboriú). Parasitological indexes were obtained after qualitative and quantitative parasitological analysis. Monogenean parasites, nematodes, and cestodes were found in all facilities. Nevertheless, nematodes and monogeneans presented 100% of prevalence in P. scalare from Araquari. From the analyzed species, P. scalare showed the highest parasite richness.

ABSTRACT The ornamental fish aquaculture represents a consolidated market worldwide. In Brazil, the major volume of commercialized freshwater ornamental fish is originated from fish farms managed by small and midsized farmers. The aim of this study was to characterize the metazoan parasitic fauna associated with the main freshwater ornamental fish farmed in Southern Brazil. Between July 2014 and January 2015, 423 fishes belonging to nine freshwater species were examined: angelfish Pterophylum scalare, siamese fighting fish Betta splendens, telescope and comet goldfish Carassius auratus, zebrafish Danio rerio, blood red swordtail Xiphophorus helleri, caramel and wagtail platy fish Xiphophorus maculatus, black molly Poecilia sphenops, white cloud mountain minnow Tanichthys albonubes and goldfinned barb Puntius sachsii. Water quality was measured in fishponds from each facility. Specimens were obtained from three ornamental fish farms located in three micro-regions in the State of Santa Catarina (Biguaçu, Camboriú e Joinville). Parasitological indexes were obtained after parasitological analysis of mucus, gills, and eyes. Trichodinids, Piscinoodinium pillulare, and Ichthyophthirius multifiliis were found in all fish farms analyzed. However, P. pillulare showed the greatest prevalence and mean intensity, compared to the other protozoa analyzed. 75% prevalence and mean intensity 57.5 were observed in the gills of P. scalare from fish farm Araquari. This study showed that fish farm Biguaçu, was the facility presenting the greatest parasite diversity. P. scalare and C. auratus were the most parasitized fish species presenting the higher richness when compared to another species. These ornamental species are widely traded and require greater care in cultivation because it is essential to produce healthy fish with attractive features accepted by the market.

ABSTRACT The objective of this study was to evaluate the chemical composition and the fermentative parameters of heart of palm waste produced from Alexander Palm, ensiled with chemical additives. Treatments consisted of silage of the sheath with or without calcium oxide. In the silage without calcium oxide, we evaluated the control silage (without additive) and the silage enriched with 5.0 g kg−1 urea (urea). In the silage with calcium oxide, we evaluated the silage enriched with 5.0 g kg−1 calcium oxide (control) and the silage enriched with 5.0 g kg−1 urea and 5.0 g kg−1 calcium oxide (urea). Experimental silos were distributed in a completely randomized design in a 2 × 2 factorial arrangement (inclusion or lack of lime × inclusion or lack of urea), with four replicates. Crude protein concentration was greater in the silages that received urea, whereas in the case of neutral detergent fiber and acid detergent fiber, the lowest levels were found in the control silage. Control silage had the lowest pH (3.75) and the silages that received lime displayed the lowest lactic acid content. Effluent losses were greater in the control silage and in the silage with lime (56.1 kg t−1 and 58.4 kg t−1, respectively). Silages prepared with waste from heart of palm production and enriched only with urea showed a better chemical composition and improved fermentation parameter estimates. We recommend the use of this waste only with additives that can improve the chemical characteristics of the forage. Without additives, unwanted fermentation processes may occur and compromise the quality of the silage.

ABSTRACT Increasing antimicrobial resistance in Salmonella species has been a serious problem for public health worldwide. This study examines Salmonella spp. recovered from foods and clinical samples on serotype, antimicrobial resistance and PFGE genotypes. It identified 91 salmonellae, belonging to 31 different serotypes, from 36 isolates from food and 55 clinical samples. Salmonella Infantis (16.5%) and Salmonella Enteritidis (13.7%) are the most common among food isolates, whereas Salmonella Enteritidis (29.0%) and Salmonella Typhimurium (16.0%) mainly causes human salmonellosis. Antimicrobial susceptibility data showed that 63.0% of the isolates were fully susceptible to 12 antibiotics tested. Nalidixic acid showed high resistance rates, 32.7% and 25.0% of the clinical isolates and food, respectively. Three main PFGE types: A (Salmonella Enteritidis), B (Salmonella Infantis) and C (Salmonella Schwarzengrund) comprised isolates recovered from foods and clinical samples. Our results indicate that the clonal groups were both causing diseases and food contamination, emphasizing the need to maintain a system of surveillance for foodborne disease.

RESUMO Objetivo: analisar os fatores associados ao óbito em pacientes com lesão diafragmática atendidos em hospital de referência para o trauma. Métodos: estudo retrospectivo de pacientes com lesão do diafragma atendidos no Hospital Risoleta Tolentino Neves da Universidade Federal de Minas Gerais entre janeiro de 2010 e dezembro de 2014. Foi utilizado o Banco de Registros de Trauma Collector® (MD, USA). Utilizaram-se dados demográficos, localização da lesão diafragmática, lesões associadas de outros órgãos, número de lesões associadas, tipo de abordagem terapêutica, complicações e o escore de gravidade Injury Severity Score (ISS). A variável de interesse foi a ocorrência de óbito. Resultados: foram identificados 103 pacientes e a incidência de óbito foi de 16,5%. Lesões penetrantes ocorreram em 98% dos pacientes. Em análise univariada a mortalidade foi maior em pacientes cujo tratamento foi não operatório, sem rafia (p=0,023), e menor em pacientes submetidos à rafia diafragmática (p<0,001). O aumento do número de lesões associou-se ao aumento da incidência de óbitos (p=0,048). Em análise multivariada, ISS>24 (OR=4,0; p=0,029) e rafia do diafragma (OR=0,76; p<0,001) associaram-se à mortalidade. Conclusão: os achados indicam que a ruptura traumática do diafragma raramente se apresenta como lesão isolada, estando associada frequentemente à lesão de outros órgãos, especialmente fígado e vísceras ocas. Pode-se afirmar que a mortalidade foi mais elevada entre aqueles com ISS>24.

ABSTRACT Objective: to analyze the factors associated with death in patients with diaphragmatic injury treated at a trauma reference hospital. Methods: we conducted a retrospective study of patients with diaphragm injury attended at the Risoleta Tolentino Neves Hospital of the Federal University of Minas Gerais, between January 2010 and December 2014. We used The Collector® database of trauma records (MD, USA). We gathered data on demographics, location of the diaphragmatic lesion, site and number of associated lesions, type of therapeutic approach, complications and Injury Severity Score (ISS). The variable of interest was the occurrence of death. Results: we identified 103 patients and mortality was 16.5%. Penetrating lesions occurred in 98% of patients. Univariate analysis showed a mortality higher in patients whose treatment was non-operative, without closing of the defect (p=0.023), and lower in patients submitted to diaphragmatic suturing (p<0.001). The increase in the number of lesions was associated with an increase in mortality (p=0.048). In multivariate analysis, ISS>24 (OR=4.0, p=0.029) and diaphragmatic suturing (OR=0.76, p<0.001) were associated with mortality. Conclusion: The findings indicate that the traumatic rupture of the diaphragm rarely presents as an isolated lesion, being frequently associated with injuries of other organs, especially the liver and hollow viscera. Mortality was higher among those with ISS>24.

ABSTRACT Parasitic isopods of fishes usually show wide distribution and low host specificity. This study investigated the occurrence of gill parasites in 120 specimens of spotted goatfish Pseudupeneus maculatus, marine fish of great economic importance for fishery community. The fish were captured monthly in the Coast of Pernambuco State, Northeast Brazil, between October 2012 and September 2013. Eleven isopods were found and identified as Rocinela signata. We observed lower infections in the gills of P. maculatus (prevalence 8.3%, mean intensity 1.6±0.3 and mean abundance 0.1±0.3) when compared to other studies of different host fishes from geographically close locations. This parasite has been reported from a wide variety of fish species, not only in Brazil, but also in the eastern Atlantic and the Pacific oceans. This is the first report of R. signata in spotted goatfish.
