Abstract Background: The emergence of multidrug-resistant NDM-1-producing enterobacteriaceae strains has become a threat to inpatients, especially to immunosuppressed ones, such as kidney transplant recipients. NDM-1 is a carbapenemase that makes gram-negative bacteria resistant to many types of antibiotics. The incidence of carbapenemase-producing enterobacteria infection in solid organ transplant recipients is around 3 to 10%, with a mortality rate of up to 30%. Methods: We present a case series of 4 patients with NDM-1-producing enterobacteria isolated in urine cultures or rectal swabs. We also conducted a cross-sectional study 30 days after patient identification, collecting surveillance cultures (rectal swab) from all inpatients to assess the extent of spread of this resistance mechanism; a total of 101 patients were included. Results: Two patients were adequately treated with negative control cultures. The other two patients were not treated because they were asymptomatic and had subsequent negative urine cultures. No new colonization was identified in the cross-sectional screening, and no new cases of urinary NDM-1 infection were recorded after a 4-year follow-up. Conclusion: Surveillance for infections caused by multidrug-resistant strains in hospitals treating immunosuppressed patients should be continued and prompt action should be taken in cases of outbreaks of multidrug-resistant infections.
Resumo Histórico: O surgimento de cepas multirresistentes de enterobacteriaceae produtoras de NDM-1 tornou-se uma ameaça para pacientes hospitalizados, especialmente para os imunossuprimidos, como os receptores de transplante renal. NDM-1 é uma carbapenemase que torna as bactérias gram-negativas resistentes a muitos tipos de antibióticos. A incidência de infecção por enterobactérias produtoras de carbapenemas em receptores de transplante de órgãos sólidos é de cerca de 3 a 10%, com uma taxa de mortalidade de até 30%. Métodos: Apresentamos uma série de casos de 4 pacientes com enterobactérias produtoras de NDM-1 isoladas em culturas de urina ou esfregaços retais. Também realizamos um estudo transversal 30 dias após a identificação do paciente, coletando culturas de vigilância (esfregaço retal) de todos os pacientes internados para avaliar a extensão de disseminação deste mecanismo de resistência; foram incluídos um total de 101 pacientes. Resultados: Dois pacientes foram tratados adequadamente com culturas de controle negativo. Os outros dois pacientes não foram tratados porque eram assintomáticos e tiveram culturas de urina negativas subsequentes. Não foi identificada nenhuma nova colonização na triagem transversal, e não foram registrados novos casos de infecção urinária por NDM-1 após um acompanhamento de 4 anos. Conclusão: A vigilância de infecções causadas por cepas multirresistentes em hospitais que tratam pacientes imunossuprimidos deve ser continuada e devem ser tomadas medidas imediatas em casos de surtos desses tipos de infecções.

RESUMO Aplicações exógenas de compostos químicos estimulam modificações no metabolismo vegetal e conferem tolerância a diferentes estresses ambientais, incluindo o déficit hídrico. Esta pesquisa teve como objetivo avaliar os efeitos do uso de ácido salicílico (AS) e prolina na redução do estresse hídrico em uma variedade tradicional de feijão-caupi em um clima típico do semiárido brasileiro. Foi utilizado um delineamento inteiramente casualizado em esquema fatorial 2 × 4 com cinco repetições. Foram utilizadas duas lâminas de irrigação, correspondentes a 100% (W100) e 50% da evapotranspiração diária (W50) e quatro tratamentos com atenuadores: controle (água destilada), AS (550 mg L-1), prolina (690 mg L-1) e 690 mg L-1 prolina + 550 mg L-1 AS. Os elicitores promoveram alterações no metabolismo osmótico e antioxidante, o que pode contribuir para o mecanismo de tolerância das plantas de feijão-caupi sob restrição hídrica. A aplicação de ácido salicílico aumentou a síntese de osmorreguladores, a concentração de proteínas e modulou a atividade de enzimas antioxidantes em plantas de feijão-caupi sob estresse. A concentração de prolina aumentou sinergicamente nas plantas tratadas com prolina e AS, principalmente em 50% de reposição de água.
ABSTRACT Exogenous applications of chemical compounds stimulate changes in plant metabolism and promote tolerance to different environmental stresses, including water deficit. This study aimed to evaluate the ability of salicylic acid (SA) and proline (PRO) to reduce water stress in a traditional variety of cowpea in a typical Brazilian semiarid climate. A completely randomized design was used in a 2 × 4 factorial scheme, with five replicates. Two irrigation regimes were evaluated corresponding to 100% (W100) and 50% of daily evapotranspiration (W50), respectively, with the addition of the following four attenuators: control (distilled water), SA (550 mg L-1), PRO (690 mg L-1), and 690 mg L-1 PRO + 550 mg L-1 SA. The treatments promoted changes in osmotic and antioxidant metabolism, which may contribute to the tolerance mechanisms of cowpea plants to water stress. The application of SA increased osmoregulator synthesis and protein concentrations, and modulated antioxidant enzyme activity in the cowpea plants under water stress. PRO concentrations increased synergistically in plants treated with PRO and SA, particularly in 50% of water replacement.

The copper alloy UNS-C27200 is a binary brass, composed of 38wt%Zn, beeing one of the most used in the industry. The union of Cu-Zn alloys by conventional welding by fusion in thin plates presents several challenges. The Friction Stir Welding (FSW) process performs the union of two, or more materials, through a rotating tool that travels throughout the welding region. One the great advantages of FSW is working below the melting point of the material, which reduces the change in the microstructure and properties of the material, when compared to conventional welding processes. Due to the lack of research on FSW process in lap brass joints with thin thicknesses, the present work aims to expand these studies in order to contribute to future research. Eight conditions were evaluated, varying rotation and welding speed. In the best results by visual inspection, analyzes of microstructure, temperature, microhardness and mechanical strength were performed. The better welding results were obtained with ω=1050 rpm and ν=20 mm/min. There was reduction of approximately 50% between Stir Zone and Base metal. The mechanical strength was affected by the pin hole resulting from the process. The microstructure revealed a homogeneous mixture in the stir zone and no defects were detected.

Abstract The Program for Biodiversity Research (PPBio) is an innovative program designed to integrate all biodiversity research stakeholders. Operating since 2004, it has installed long-term ecological research sites throughout Brazil and its logic has been applied in some other southern-hemisphere countries. The program supports all aspects of research necessary to understand biodiversity and the processes that affect it. There are presently 161 sampling sites (see some of them at Supplementary Appendix), most of which use a standardized methodology that allows comparisons across biomes and through time. To date, there are about 1200 publications associated with PPBio that cover topics ranging from natural history to genetics and species distributions. Most of the field data and metadata are available through PPBio web sites or DataONE. Metadata is available for researchers that intend to explore the different faces of Brazilian biodiversity spatio-temporal variation, as well as for managers intending to improve conservation strategies. The Program also fostered, directly and indirectly, local technical capacity building, and supported the training of hundreds of undergraduate and graduate students. The main challenge is maintaining the long-term funding necessary to understand biodiversity patterns and processes under pressure from global environmental changes.

RESUMO O carcinoma de células escamosas é uma neoplasia maligna que afeta as estruturas e os tecidos da cavidade oral. Interleucinas (IL) sintetizadas a partir de um tumor modulam uma cascata de reações que poderá influenciar o prognóstico da doença. Objetiva-se investigar na literatura se as interleucinas são mediadores que influenciam negativamente ou positivamente o prognóstico de pacientes com carcinoma de células escamosas intraoral. Um estudo de revisão sistemática foi realizado segundo as instruções do Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). As bases de dados PubMed (incluindo MedLine), Scopus, Web of Science, SciELO e Latin American and Caribbean Health Sciences (LILACS) foram utilizadas como fontes de estudo primárias; OpenGrey e OpenThesis, utilizadas para pesquisar a "literatura cinzenta". A busca realizada em sete bases de dados gerais resultou em um conjunto de 858 estudos, enquanto a realizada em duas bases de dados para literatura cinza, em 82 estudos, totalizando 940 pesquisas. Destas, 15 foram selecionadas para a presente revisão sistemática (oito estudos apresentaram baixo risco de viés; quatro, moderado risco de viés; e três, alto risco de viés). Apesar de poderem atuar nas vias de resposta imune antitumoral, as IL avaliadas nesta revisão (IL-4, IL-6, IL-8, IL-10, IL-12 e IL-13) tendem a apresentar uma resposta associada à intensificação do processo de carcinogênese e ao prognóstico desfavorável em pacientes portadores do carcinoma de células escamosas intraoral.
ABSTRACT Squamous cell carcinoma is a malignant neoplasm that affects the structures and tissues of the oral cavity. Interleukins (IL) synthesized from a tumor modulate a cascade reaction that may influence the prognosis of the disease. We aim to investigate in the literature whether interleukins are mediators that negatively or positively influence the prognosis of patients with oral squamous cell carcinoma. A systematic review study was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes (PRISMA) instructions. PubMed (including MedLine), Scopus, Web of Science, SciELO and Latin American and Caribbean Health Sciences (LILACS) databases were used as the primary sources for the study; OpenGrey and OpenThesis were used to search for "gray literature". The search conducted in seven general databases resulted in a set of 858 studies, while the search conducted in two databases for gray literature resulted in 82 studies, totaling 940 studies. From these, 15 studies were selected for this systematic review (eight studies presented low bias risk; four studies presented moderate bias risk; and three studies presented high risk of bias). Although they may act on the anti-tumor immune response pathways, the IL evaluated in the present systematic review (IL-4, IL-6, IL-8, IL-10, IL-12 and IL-13) tend to present a response associated with the intensification of carcinogenesis and poor prognosis in patients with oral squamous cell carcinoma.

Abstract The aim of this investigation was to study the degradation of tributyl phosphate (TBP) in aqueous solution by heterogeneous photocatalysis (UV-C/TiO2). To perform the investigation, aqueous solutions containing the contaminant were exposed to UV radiation in the absence or presence of TiO2 in suspension or supported on a Fe-Cr metal alloy plate. TBP analyses before and after the treatment were performed by Ultra-Performance Liquid Chromatography (UPLC) in order to quantify the contaminant degradation. The results showed that the TiO2 photocatalytic system was able to remove TBP from the solution and the formation of some by-products was observed. TiO2 photocatalytic systems were able to reduce acute toxicity in an Artemia Salina bioassay according to the increase in LC50 from 10.2 ± 0.5%(v/v) to 16.9 ± 0.6 %(v/v) for the immobilized system and to levels which were not possible to detect by the applied method any more for the suspension system.

Improving the development of modified release matrix systems strictly depends on selecting an appropriate agent capable of controlling the drug's release. In this study, Adenanthera pavonina galactomannan was investigated as a potential basis for developing a controlled release of rutin. This galactomannan was extracted, purified and characterized by GPC, NMR and FT-IR spectroscopy. The mannose/galactose ratio (M/G) of 1.46 was calculated by the relative area from signals of the anomeric region of 1H-NMR spectrum. The main chain of this galactomannan consists of β(1®4)-D-mannose and α(1®6)-D-galactose linked units (1H-decoupled 13C NMR, 13C DEPT 135º NMR and HSQC spectra). The sustained-release tablets containing rutin and galactomannan were compared with the extensively investigated hydrophilic matrix HPMC. Drug release analysis revealed similar release mechanism for both matrices. A new formulation for controlled drug delivery from water-swellable matrix systems is proposed.

ABSTRACT Ischemia is responsible for many metabolic abnormalities in the heart, causing changes in organ function. One of modifications occurring in the ischemic cell is changing from aerobic to anaerobic metabolism. This change causes the predominance of the use of carbohydrates as an energy substrate instead of lipids. In this case, the glycogen is essential to the maintenance of heart energy intake, being an important reserve to resist the stress caused by hypoxia, using glycolysis and lactic acid fermentation. In order to study the glucose anaerobic pathways utilization and understand the metabolic adaptations, New Zealand white rabbits were subjected to ischemia caused by Inflow occlusion technique. The animals were monitored during surgery by pH and lactate levels. Transcription analysis of the pyruvate kinase, lactate dehydrogenase and phosphoenolpyruvate carboxykinase enzymes were performed by qRT-PCR, and glycogen quantification was determined enzymatically. Pyruvate kinase transcription increased during ischemia, followed by glycogen consumption content. The gluconeogenesis increased in control and ischemia moments, suggesting a relationship between gluconeogenesis and glycogen metabolism. This result shows the significant contribution of these substrates in the organ energy supply and demonstrates the capacity of the heart to adapt the metabolism after this injury, sustaining the homeostasis during short-term myocardial ischemia.

RESUMO: Avaliou-se neste estudo a atividade antimicrobiana e a toxicidades aguda e crônica do extrato da entrecasca de Stryphnodendron adstringens. A partir do extrato seco, obtido através da maceração estática da casca do caule em etanol de cereais, foi realizada a quantificação de taninos totais (32,7%) pelo método de Folin-Denis. A atividade antimicrobiana do extrato seco extraído de cascas do caule de S. adstringens foi avaliada pela técnica de disco-difusão para os micro-organismos Escherichia coli (ATCC 25922) e Staphylococcus aureus (ATCC 25923) nas concentrações de 200, 400 e 600μL/mL. Os testes de concentração inibitória mínima revelaram que 600μL/mL inibiu o crescimento dos dois micro-organismos testados; o mesmo resultado foi observado para atividade bactericida na concentração de 600μL/mL sobre essas espécies. Efeitos tóxicos sistêmicos agudos e crônicos do extrato seco de S. adstringens administrados por gavagem foram estudados em ratos Wistar, utilizando as doses de 400, 600 e 800mg/kg. Foi observada degeneração hepática no grupo de animais que receberam 800mg/kg tanto no estudo da toxicidade aguda quanto crônica, que pode indicar algum grau de toxicidade de S. adstringens nessa concentração. Considerando o amplo uso de S. adstringens como fitoterápico para humanos e animais, atenção deve ser dispensada para ingestão em altas doses mediante os efeitos tóxicos observados neste estudo.
ABSTRACT: This study evaluated the antimicrobial activity and acute or chronic toxicity of the extract of Stryphnodendron adstringens. The stem bark dry extract was obtained by static maceration with ethanol. Quantification of tannins was performed by the Folin-Denis method, which indicated a total tannin content of 32.7%. The antimicrobial activity of the dry extract of S. adstringens was evaluated by agar-based disk diffusion assay with Escherichia coli (ATCC 25922) and Staphylococcus aureus (ATCC 25923) in the concentration of 200, 400 and 600μL/mL. The results indicated that 600μL/mL inhibited microbial growth, i.e. had antimicrobial activity against these species. Acute and chronic toxic effects of S. adstringens was evaluated in Wistar rats treated with 200, 400, 600 and 800mg/kg of extract, administrated by gavage. Liver degeneration was observed in the group of rats receiving 800mg/kg in chronic exposure, what may indicate some degree of toxicity at this concentration. However, no systemic toxicity was observed at lower doses. Considering the broad use of S. adstringens as a phytotherapeutic agent for various human and animal diseases and the livertoxicity observed at high concentrations, attention should be paid to the possible adverse effect of using the extract from this plant at high concentration.

ABSTRACT Background. Hepatocellular carcinoma (HCC) is the most common malignancy that develops in cirrhotic livers. Its clinical and epidemiological characteristics and mortality rates vary according to geographical region. The objective of this study was to evaluate the clinical profile, epidemiological characteristics, laboratory parameters, treatment and survival of patients with HCC. Material and methods. Patients with HCC seen between 2000 and 2012 were studied. The Kaplan-Meier method was used for survival analysis according to variables in question. Results. The study included 247 patients with a mean age of 60 ± 10 years. There was a predominance of males (74%). The main etiologies of HCC were HCV infection (55%), excessive alcohol consumption (12%), and HBV infection (8%). Liver cirrhosis was present in 92% of cases. The mean tumor number and diameter were 2 and 5 cm, respectively. Patients meeting the Milan criteria corresponded to 43% of the sample. Liver transplantation was performed in 22.4% of patients of the Milan subset and in 10% of the whole sample. The overall mean survival was 60 months, with a 1-, 3- and 5-year survival probability of 74%, 40% and 29%, respectively. Lower survival was observed among patients with alcoholic etiology. Survival was higher among patients submitted to liver transplantation (P < 0.001), TACE (P < 0.001), or any kind of treatment (P < 0.001). However, no difference was found for surgical resection (P = 0.1) or sorafenib (P = 0.1). Conclusion. Patients with HCC were mainly older men diagnosed at an advanced stage. Treatment was associated with better overall survival, but few patients survived to be treated.

RESUMOObjetivo:analisar a implantação de registro de trauma em hospital universitário com atendimento ao SUS, bem como, sua capacidade em identificar pontos para melhorada qualidade no atendimento.Métodos:o grupo de coleta de dados foi composto por alunos dos cursos de medicina e enfermagem, orientados pelos coordenadores do projeto. Utilizamos o software itreg (ECO Sistemas-RJ/SBAIT) como ferramenta de banco de dados. Vários "filtros" de qualidade foram propostos no intuito de selecionar os casos a serem revistos no processo de controle de qualidade.Resultados:entre março e novembro de 2014, foram inseridos no itreg dados de 1344 vítimas de trauma. Cerca de 87% foram vítimas de trauma fechado, 59,6% apresentaram RTS>7,0 e, 67%, ISS<9. Os registros foram completos em 292 casos, que foram selecionados para a revisãono programa de qualidade. Os filtros de auditoria mais frequentemente anotadosforam a laparotomia após quatro horas da admissão e a drenagem dos hematomas subdurais agudos após quatro horas da admissão. Identificamos vários pontos a serem desenvolvidos, como o controle da "supertriagem" de doentes, a necessidade de diminuição do número de exames de imagem negativos, o desenvolvimento de protocolos para passagem de acessos venosos centrais e tratamento de trauma craniencefálico grave.Conclusão:o Registro de Trauma traz uma visão clara dos pontos a serem melhorados no atendimento ao traumatizado, contudo, há características específicas na implantação desta ferramenta.
ABSTRACTObjective:to analyze the implementation of a trauma registry in a university teaching hospital delivering care under the unified health system (SUS), and its ability to identify points for improvement in the quality of care provided.Methods:the data collection group comprised students from medicine and nursing courses who were holders of FAPESP scholarships (technical training 1) or otherwise, overseen by the coordinators of the project. The itreg (ECO Sistemas-RJ/SBAIT) software was used as the database tool. Several quality "filters" were proposed to select those cases for review in the quality control process.Results:data for 1344 trauma patients were input to the itreg database between March and November 2014. Around 87.0% of cases were blunt trauma patients, 59.6% had RTS>7.0 and 67% ISS<9. Full records were available for 292 cases, which were selected for review in the quality program. The auditing filters most frequently registered were laparotomy four hours after admission and drainage of acute subdural hematomas four hours after admission. Several points for improvement were flagged, such as control of overtriage of patients, the need to reduce the number of negative imaging exams, the development of protocols for achieving central venous access, and management of major TBI.Conclusion: the trauma registry provides a clear picture of the points to be improved in trauma patient care, however, there are specific peculiarities for implementing this tool in the Brazilian milieu.

This paper describes the studies performed to determine the purity of aldrin samples, an organochlorine pesticide, using the mass balance approach. The organic impurities were identified and quantified by gas chromatography-mass spectrometry (GC-MS), gas chromatography with flame ionization detection (GC-FID) and gas chromatography with electron capture detector (GC‑µECD) using two columns: DB-35ms (intermediate polarity) and DB-XLB (low polarity). The water content was determined by Karl Fischer coulometric titration, and the inorganics were analyzed by inductively coupled plasma mass spectrometry (ICP-MS). The aldrin contents determined by mass balance and quantitative nuclear magnetic resonance (qNMR) were compared. The obtained results were validated through the participation of the National Institute of Metrology, Quality and Technology (Inmetro) in the key-comparison CCQM-K55.b organized by the Organic Analysis Working Group/International Bureau of Weights and Measures (OAWG/BIPM).

Objectives To evaluate if the different results of prostate cancer risk between black and white Brazilian men may be associated with the varying methodology used to define participants as either Blacks or Whites. Patients and Methods We evaluated median PSA values, rate of PSA level ≥4.0 ng/mL, indications for prostate biopsy, prostate cancer detection rate, biopsy/cancer rate, cancer/biopsy rate, and the relative risk of cancer between blacks versus whites, blacks versus non-blacks (browns and whites), non-whites (browns and blacks) versus whites, African versus non-African descendants, and African descendants or blacks versus non-African descendants and non-blacks. Results From 1544 participants, there were 51.4% whites, 37.2% browns, 11.4% blacks, and 5.4% African descendants. Median PSA level was 0.9 ng/mL in whites, browns, and non-African descendants, compared to 1.2 ng/mL in blacks, and African descendants or blacks, and 1.3 ng/mL in African descendants. Indications for prostate biopsy were present in 16.9% for African descendants, 15.9% of black, 12.3% of white, 11.4% for non-African descendants, and 9.9% of brown participants. Prostate cancer was diagnosed in 30.3% of performed biopsies: 6.2% of African descendants, 5.1% of blacks, 3.3% of whites, 3.0% of non-African descendants, and 2.6% of browns. Conclusions Median PSA values were higher for Blacks versus Whites in all classification systems, except for non-white versus white men. The rate of prostate biopsy, prostate cancer detection rate, and relative risk for cancer was increased in African descendants, and African descendants or blacks, compared to non-African descendants, and non-African descendants and non-blacks, respectively.

Resumo Um levantamento atualizado das plantas com sementes e análises relevantes acerca desta biodiversidade são apresentados. Este trabalho se iniciou em 2010 com a publicação do Catálogo de Plantas e Fungos e, desde então vem sendo atualizado por mais de 430 especialistas trabalhando online. O Brasil abriga atualmente 32.086 espécies nativas de Angiospermas e 23 espécies nativas de Gimnospermas e estes novos dados mostram um aumento de 3% da riqueza em relação a 2010. A Amazônia é o Domínio Fitogeográfico com o maior número de espécies de Gimnospermas, enquanto que a Floresta Atlântica possui a maior riqueza de Angiospermas. Houve um crescimento considerável no número de espécies e nas taxas de endemismo para a maioria dos Domínios (Caatinga, Cerrado, Floresta Atlântica, Pampa e Pantanal), com exceção da Amazônia que apresentou uma diminuição de 2,5% de endemicidade. Entretanto, a maior parte das plantas com sementes que ocorrem no Brasil (57,4%) é endêmica deste território. A proporção de formas de vida varia de acordo com os diferentes Domínios: árvores são mais expressivas na Amazônia e Floresta Atlântica do que nos outros biomas, ervas são dominantes no Pampa e as lianas apresentam riqueza expressiva na Amazônia, Floresta Atlântica e Pantanal. Este trabalho não só quantifica a biodiversidade brasileira, mas também indica as lacunas de conhecimento e o desafio a ser enfrentado para a conservação desta flora.
Abstract An updated inventory of Brazilian seed plants is presented and offers important insights into the country's biodiversity. This work started in 2010, with the publication of the Plants and Fungi Catalogue, and has been updated since by more than 430 specialists working online. Brazil is home to 32,086 native Angiosperms and 23 native Gymnosperms, showing an increase of 3% in its species richness in relation to 2010. The Amazon Rainforest is the richest Brazilian biome for Gymnosperms, while the Atlantic Rainforest is the richest one for Angiosperms. There was a considerable increment in the number of species and endemism rates for biomes, except for the Amazon that showed a decrease of 2.5% of recorded endemics. However, well over half of Brazillian seed plant species (57.4%) is endemic to this territory. The proportion of life-forms varies among different biomes: trees are more expressive in the Amazon and Atlantic Rainforest biomes while herbs predominate in the Pampa, and lianas are more expressive in the Amazon, Atlantic Rainforest, and Pantanal. This compilation serves not only to quantify Brazilian biodiversity, but also to highlight areas where there information is lacking and to provide a framework for the challenge faced in conserving Brazil's unique and diverse flora.
