Travellers' Types

This paper uses subjects’ self-reported justifications to explain discrepancies between observed heterogeneous behavior and the unique equilibrium prediction in a one-shot traveler’s dilemma experiment (TD). Principal components (PC) analysis suggests that iterative reasoning, aspiration levels, competitive behavior, attitudes towards risk and penalties and focal points may be behind different choices. Such reasons are coherent with same subjects’ behavior in other tests and experiments in which these particular issues are prominent. Overall, we identify types of subjects whose motivations are consistent across tasks.

Collision tumour involving a rectal gastrointestinal stromal tumour with invasion of the prostate and a prostatic adenocarcinoma

Background: Gastrointestinal stromal tumours (GISTs) are the most common primary mesenchymal neoplasia in the gastrointestinal tract, although they represent only a small fraction of total gastrointestinal malignancies in adults (<2%). GISTs can be located at any level of the gastrointestinal tract; the stomach is the most common location (60-70%), in contrast to the rectum, which is most rare (4%). When a GIST invades into the adjacent prostate tissue, it can simulate prostate cancer. In this study, we report on a case comprising the unexpected collision between a rectal GIST tumour and a prostatic adenocarcinoma. Findings: We describe the complexity of the clinical, endoscopic and radiological diagnosis, of the differential diagnosis based on tumour biopsy, and of the role of neoadjuvant therapy using imatinib prior to surgical treatment. Conclusions: Although isolated cases of coexisting GISTs and prostatic adenocarcinomas have reviously been described, this is the first reported case in the medical literature of a collision tumour involving a rectal GIST and prostatic adenocarcinoma components.

Celiac disease in the Mediterranean area

Background: The World Gastroenterology Organization recommends developing national guidelines for the diagnosis of Celiac Disease (CD): hence a profile of the diagnosis of CD in each country is required. We aim to describe a cross-sectional picture of the clinical features and diagnostic facilities in 16 countries of the Mediterranean basin. Since a new ESPGHAN diagnostic protocol was recently published, our secondary aim is to estimate how many cases in the same area could be identified without a small intestinal biopsy. Methods: By a stratified cross-sectional retrospective study design, we examined clinical, histological and laboratory data from 749 consecutive unselected CD children diagnosed by national referral centers. Results: The vast majority of cases were diagnosed before the age of 10 (median: 5 years), affected by diarrhea, weight loss and food refusal, as expected. Only 59 cases (7.8%) did not suffer of major complaints. Tissue transglutaminase (tTG) assay was available, but one-third of centers reported financial constraints in the regular purchase of the assay kits. 252 cases (33.6%) showed tTG values over 10 times the local normal limit. Endomysial antibodies and HLA typing were routinely available in only half of the centers. CD was mainly diagnosed from small intestinal biopsy, available in all centers. Based on these data, only 154/749 cases (20.5%) would have qualified for a diagnosis of CD without a small intestinal biopsy, according to the new ESPGHAN protocol. Conclusions: This cross-sectional study of CD in the Mediterranean referral centers offers a puzzling picture of the capacities to deal with the emerging epidemic of CD in the area, giving a substantive support to the World Gastroenterology Organization guidelines.

Infraestructuras verdes : análisis de la práctica de los anillos verdes

En los últimos años, alcanzar la Economía Verde parece ser la aspiración perseguida por la sociedad, dado que representa un paso decisivo para lograr el Desarrollo Sostenible y con ello una ciudad sostenible. Sin embargo, las ciudades de todo el mundo han experimentado cambios en su fisonomía debido a los continuos procesos de urbanización que han fomentado un crecimiento desmedido de las mismas, además de generar una serie de efectos negativos que las alejan del camino hacia la sostenibilidad. De tal manera, que a medida que dicho crecimiento aumenta, cada vez son menores las áreas verdes localizadas en las periferias de las ciudades. Para responder a estos problemas asociados al crecimiento urbano y, por ende, al consumo de tierra, se han diseñado diversos instrumentos entre los que destaca la práctica de los Anillos Verdes, siendo el estudio de dicha práctica el objetivo de este trabajo. Con el fin de tener una amplia visión de la implementación de la práctica de los Anillos Verdes, en primer lugar, se describen de manera general algunos casos a nivel internacional, para, a continuación, profundizar en algunas de las principales prácticas europeas y españolas, confirmando, de este modo, que representan una práctica muy extendida en Europa, mientras que en España todavía se encuentran en un estado emergente.

Diseño y fabricación de un instrumento coaxial para cirugía laparoscópica.

[ES]En este trabajo se ha diseñado un producto secundario con una fijación extra en formato trocar para operaciones percutáneas dirigidas por sistemas de imagen. Este instrumento que hasta ahora era inexistente en el mercado actuará como túnel, permitiendo la introducción de agujas de radiofrecuencia y biopsia por su interior. La particularidad de este producto es el diseño del sistema de sujeción, que garantizará al cirujano que el punto a intervenir sea el mismo durante toda la operación. Este diseño se ha realizado después de hacer un estudio en profundidad de las alternativas existentes de los sistemas de fijación en el campo de la medicina oncológica y el sector industrial. Además se detalla el material de cada elemento del producto en base a la norma sanitaria correspondiente, también se explica el proceso más adecuado para la fabricación de dichos elementos y por último se realiza un cálculo sencillo del pandeo de la aguja, que garantice un uso óptimo del instrumento.
