ABSTRACT
Abstract Mycotic pseudoaneurysms of the superficial femoral artery (SFA) are rare and are usually secondary to colonization of an atherosclerotic plaque during an episode of bacteremia. We describe the case of a 68 year-old diabetic male who presented to the Emergency Department with pyrexia and a painful expanding mass in the left thigh. He had a history of diarrhea and had been treated 16 days earlier for an SFA pseudoaneurysm that had been excluded with a covered stent with no adjunctive antibiotic therapy. Angio CT showed an abscess surrounding femoral vessels and stent thrombosis. Under general anesthesia, we performed extensive debridement, removal of the endovascular material, SFA ligation, and empirical antibiotic therapy. Blood and tissue cultures were positive for Escherichia coli. At the 3-months follow up visit, the patient reported he had no claudication. In selected patients, mycotic pseudoaneurysms can be treated by SFA ligation.
Resumo Pseudoaneurismas micóticos da artéria femoral superficial (AFS) são raros, e geralmente são secundários à colonização de uma placa aterosclerótica durante bacteremia. Relatamos o caso de um paciente masculino diabético de 68 anos que chegou ao Serviço de Emergência com pirexia e massa expansiva dolorosa na coxa esquerda. Apresentava histórico de diarreia e havia sido tratado 16 dias antes para pseudoaneurisma da AFS, que foi excluído com stent coberto e sem antibioticoterapia adjuvante. A angiotomografia computadorizada demonstrou um abscesso ao redor dos vasos femorais e trombose do stent. Sob anestesia geral, realizamos desbridamento extenso, remoção do material endovascular, ligadura de AFS e antibioticoterapia empírica. Culturas de sangue e tecidos foram positivas para Escherichia coli. Na consulta de seguimento aos 3 meses, o paciente negou claudicação. Em pacientes selecionados, pseudoaneurismas micóticos podem ser tratados com ligadura de AFS.

RESUMO: O estudo objetivou analisar a estrutura fatorial e as propriedades psicométricas da Escala de Suporte à Transferência de Treinamento (ESTT) e sua relação com a efetividade do treinamento no trabalho. Um total de 1.540 funcionários de um banco estatal brasileiro participou do estudo respondendo à ESTT e à escala de impacto do treinamento no trabalho em amplitude depois de realizar um curso online. Foram realizadas análises de consistência interna, fatorial confirmatória e de regressões múltiplas. Uma estrutura com três fatores foi encontrada, bem como um alto nível de ajuste para os modelos. As medidas apresentam evidências de validade de construto e o suporte percebido pelos participantes esteve positivamente relacionado com a transferência de competências para o trabalho e desempenho geral.
ABSTRACT: This study aimed to analyze the factor structure and psychometric properties of a Training Transfer Support Scale (STTS) and its relationship with the effectiveness of training at work. A total of 1,540 employees of a public Brazilian bank participated in this study by responding to the STTS and a measure of transfer of training after taking part in an online course. Reliability analysis, confirmatory factor analysis, and multiple regressions were conducted. A three-factor structure was found and a high level of fit for the models. Evidence of the construct validity of the measures was obtained, and the participants' perception of support was positive related to the transfer of training to the workplace and overall performance.
ABSTRACT
Abstract Since learning strategies seem to be an important set of variables to explain the effectiveness of training and e-learning in organizations is here to stay, this paper aimed to analyze the factor structure and psychometric properties of a Learning Strategies Scale (LSS) and its relationship with the training transfer in an e-learning corporate context. A total of 3600 employees of a Brazilian bank participated in this study by responding to the LSS after taking part in an online course. We measured training transfer with self-evaluation and hetero-evaluation scales. Internal consistency, confirmatory factor analysis, and multiple regressions were conducted. A four-factor structure and an acceptable level of fit for the model were found. All types of learning strategies were related to training transfer in self-evaluation, and the cognitive and help-seeking strategies contributed to explain training transfer in hetero-evaluation. As a reliable and valid measure that predicts the effectiveness of training and job performance, participants should be advised about the learning strategies that produce better performance results at the workplace. Future research should use it in different contexts and samples, analyzing its relationships with other workplace variables.

Background: Postoperative leaks are the most undesirable complication of bariatric surgery and upper gastrointestinal (GI) series are routinely ordered to rule them out. Despite the published literature recommending against its routine use, it is still being customarily used in Chile. Aim: To examine the usefulness of routine upper GI series using water-soluble iodinated contrast media for the detection of early postoperative leaks in patients undergoing bariatric surgery. Material and Methods: A cohort of 328 patients subjected to bariatric surgery was followed from October 2012 to October 2013. Most of them underwent sleeve gastrectomy. Results: Upper GI series on the first postoperative day were ordered to 308 (94%) patients. Postoperative leaks were observed in two patients, with an incidence of 0.6%. The sensitivity for upper GI series detection of leak was 0% and the negative predictive value was 99%. Conclusions: Routine upper GI series after bariatric surgery is not useful for the diagnosis of postoperative leak, given the low incidence of this complication and the low sensitivity of the technique.

En 47 pacientes a quienes se les efectuó un reservorio urinario continente, revisamos los estudios radiológicos realizados como control de su intervención quirúrgica. El radiólogo debe estar familiarizado con estas nuevas técnicas para efectuar una correcta evaluación posterior de ellas
