An iliac-appendiceal fistula causing gastrointestinal bleeding

© 2019 The Authors Aortoenteric fistulas are an uncommon cause of gastrointestinal bleeding, and iliac-appendiceal fistulas are an even rarer cause. We describe a case of an iliac-appendiceal fistula in a patient who presented several months after aortic reconstruction with gastrointestinal bleeding. An extensive workup revealed that the source of bleeding was localized to the appendiceal orifice. The patient underwent an appendectomy with a two-stage procedure involving the iliac graft for definitive repair and ultimately recovered well. Despite the rarity of aortoenteric and iliac-appendiceal fistulas causing gastrointestinal bleeding, keeping a high index of suspicion in patients with a prior vascular repair can prevent death

A factor confirmation and convergent validity of the " areas of worklife scale" (AWS) to Spanish translation

Background: Perceived incongruity between the individual and the job on work-life areas such as workload, control, reward, fairness, community and values have implications for the dimensions of burnout syndrome. The “Areas of Work-life Scale” (AWS) is a practical instrument to measure employees´ perceptions of their work environments. AIMS: Validate a Spanish translation of the AWS, and it relationship with Masclach Burnout Inventory dimensions. Methods: The study was conducted in three medium-sized hospitals and seven rural and urban Primary Care centres (N = 871) in Spain. The “Maslach Burnout Inventory General Survey” (MBI-GS) and AWS were applied. We developed a complete psychometric analysis of its reliability, and validity. Results: Data on the reliability supported a good internal consistency (Cronbach a between .71, and .85). Construct validity was confirmed by a six factor model of the AWS as a good measure of work environments (¿2 (352) = 806.21, p < 0.001; ¿2/df = 2.29; CFI = 0.935, RMSEA = 0.039); concurrent validity was analysed for its relationship with other measures (opposing dimensions to burnout, and MBI), and each correlation between dimensions and subdimensions were statistically significant; as well, predictive validity, by a series of Multiple Regression Analysis examined the resulting patterns of the Confirmatory Factor Analysis (CFA) confirms the relationship between the work-life areas and burnout dimensions. Conclusions: Leiter and Maslach’s AWS has been an important instrument in exploring several work-life factors that contribute to burnout. This scale can now be used to assess the quality of work-life in order to design and assess the need for intervention programs in Spanish-speaking countries

Direct multiple-point geostatistical simulation of edge properties for modeling thin irregularly-shaped surfaces

Thin irregularly-shaped surfaces such as clay drapes often have a major control on flow and transport in heterogeneous porous media. Clay drapes are often complex curvilinear 3-dimensional surfaces and display a very complex spatial distribution. Variogram-based stochastic approaches are often also not able to describe the spatial distribution of clay drapes since complex, curvilinear, continuous and interconnected structures cannot be characterized using only two-point statistics. Multiple-point geostatistics aims to overcome the limitations of the variogram. The premise of multiple-point geostatistics is to move beyond two-point correlations between variables and to obtain (cross) correlation moments at three or more locations at a time using "training images" to characterize the patterns of geological heterogeneity. Multiple-point geostatistics is able to reproduce thin irregularly-shaped surfaces such as clay drapes but is often computationally intensive. To capture the thin surfaces, a small grid cell size should be adopted for the training image. This results in large training images and a large search template size and thus a large CPU and RAM demand (Huysmans and Dassargues, 2009)

Compartilhar tarefas? Papéis e funções de pai e mãe na família contemporânea

Este estudo apresenta uma análise do exercício e da divisão de papéis e funções desempenhados por progenitores na criação e educação de seus filhos em idade escolar. Utilizou-se uma amostra de 100 famílias de nível sócio-econômico médio residentes na cidade de Porto Alegre. Foi utilizado um questionário elaborado pelo grupo de pesquisa Dinâmica das Relações Familiares. Os resultados obtidos demostraram que, de forma geral, existe um bom nível de concordância entre as respostas de pais e mães (40%) no que se refere a divisão de tarefas na criação dos filhos. Além disso, a análise de Clusters permitiu identificar dois grupos quanto ao desempenho das principais tarefas realizadas na família em relação à educação dos filhos. O Grupo I (49%) caracterizou-se por ser a mãe a principal responsável, enquanto o Grupo II (51%) caracterizou-se por haver uma divisão igualitária das tarefas entre o pai e a mãe
