Injury to the Superior Gluteal Artery during Intramedullary Fixation of a Proximal Femoral Fracture - A Case Report

Proximal femoral fractures represent a health problem of global proportions. Iatrogenic vascular lesion in the treatment of these fractures is an unusual potentially lethal complication, reported in only 0.2% of trochanteric fractures treated with intramedullary implants. Superior gluteal artery injury is extremely rare, with only two cases reported in literature.info:eu-repo/semantics/publishedVersio

Quantized Nambu-Poisson Manifolds in a 3-Lie Algebra Reduced Model

We consider dimensional reduction of the Bagger-Lambert-Gustavsson theory to a zero-dimensional 3-Lie algebra model and construct various stable solutions corresponding to quantized Nambu-Poisson manifolds. A recently proposed Higgs mechanism reduces this model to the IKKT matrix model. We find that in the strong coupling limit, our solutions correspond to ordinary noncommutative spaces arising as stable solutions in the IKKT model with D-brane backgrounds. In particular, this happens for S^3, R^3 and five-dimensional Neveu-Schwarz Hpp-waves. We expand our model around these backgrounds and find effective noncommutative field theories with complicated interactions involving higher-derivative terms. We also describe the relation of our reduced model to a cubic supermatrix model based on an osp(1|32) supersymmetry algebra.Comment: 22 page

Trabalho educativo do enfermeiro na Estratégia Saúde da Família: dificuldades e perspectivas de mudanças

Este estudo objetivou conhecer as dificuldades e perspectivas de mudanças que os enfermeiros identificam no desenvolvimento das ações educativas na Estratégia Saúde da Família (ESF). Trata-se de uma pesquisa qualitativa descritivo-exploratória. Os dados foram coletados junto a 20 enfermeiros que atuam na ESF, no âmbito da 10ª Regional de Saúde do Paraná, por meio de entrevistas semiestruturadas, no mês de abril de 2010, as quais foram submetidas à análise de conteúdo. Os resultados demonstraram que os enfermeiros enfrentam dificuldades no desenvolvimento da educação em saúde junto aos usuários, à equipe, aos gestores e quanto à falta de recursos físicos, materiais e financeiros. Mas, a partir das dificuldades sentidas, buscam alternativas diversificadas para superá-las e sugerem modificações visando à melhoria na atenção primária à saúde da população, principalmente, no que tange ao trabalho educativo

Rarity of monodominance in hyperdiverse Amazonian forests.

Tropical forests are known for their high diversity. Yet, forest patches do occur in the tropics where a single tree species is dominant. Such "monodominant" forests are known from all of the main tropical regions. For Amazonia, we sampled the occurrence of monodominance in a massive, basin-wide database of forest-inventory plots from the Amazon Tree Diversity Network (ATDN). Utilizing a simple defining metric of at least half of the trees ≥ 10 cm diameter belonging to one species, we found only a few occurrences of monodominance in Amazonia, and the phenomenon was not significantly linked to previously hypothesized life history traits such wood density, seed mass, ectomycorrhizal associations, or Rhizobium nodulation. In our analysis, coppicing (the formation of sprouts at the base of the tree or on roots) was the only trait significantly linked to monodominance. While at specific locales coppicing or ectomycorrhizal associations may confer a considerable advantage to a tree species and lead to its monodominance, very few species have these traits. Mining of the ATDN dataset suggests that monodominance is quite rare in Amazonia, and may be linked primarily to edaphic factors
