Realizado en la Escuela Politécnica Superior, por 7 profesores del centro. El objetivo era construir una herramienta software que asista al alumno de Ingeniería Técnica en Informática de Gestión e Ingeniería Informática en la elaboración del diseño de diagramas de clases y posterior implementación de sistemas software a través de un mapeo en lenguaje Java. El proyecto se ha desarrollado en 10 fases: 1. Fijación de objetivos y plan detallado; 2. Especificación del proyecto; 3. Análisis; 4. Diseño; 5. Implementación y pruebas unitarias en fases iterativas, con realimentación al diseño; 6. Pruebas de integración; 7. Liberación del prototipo de la aplicación; 8. Revisión y correcciones al prototipo; 9. Explotación de la aplicación; 10. Publicación de memoria y conclusiones. Junto a la memoria con los conocimientos técnicos se adjunta un CD-ROM con el software. Se ha conseguido una herramienta práctica y efectiva en base al objetivo propuesto y el mejor resultado es el de la generación del código.

Acute-on-chronic liver failure (ACLF) is characterized by acute decompensation (AD) of cirrhosis, organ failure(s), and high 28-day mortality. We investigated whether assessments of patients at specific time points predicted their need for liver transplantation (LT) or the potential futility of their care. We assessed clinical courses of 388 patients who had ACLF at enrollment, from February through September 2011, or during early (28-day) follow-up of the prospective multicenter European Chronic Liver Failure (CLIF) ACLF in Cirrhosis study. We assessed ACLF grades at different time points to define disease resolution, improvement, worsening, or steady or fluctuating course. ACLF resolved or improved in 49.2%, had a steady or fluctuating course in 30.4%, and worsened in 20.4%. The 28-day transplant-free mortality was low-to-moderate (6%-18%) in patients with nonsevere early course (final no ACLF or ACLF-1) and high-to-very high (42%-92%) in those with severe early course (final ACLF-2 or -3) independently of initial grades. Independent predictors of course severity were CLIF Consortium ACLF score (CLIF-C ACLFs) and presence of liver failure (total bilirubin ≥12 mg/dL) at ACLF diagnosis. Eighty-one percent had their final ACLF grade at 1 week, resulting in accurate prediction of short- (28-day) and mid-term (90-day) mortality by ACLF grade at 3-7 days. Among patients that underwent early LT, 75% survived for at least 1 year. Among patients with ≥4 organ failures, or CLIF-C ACLFs >64 at days 3-7 days, and did not undergo LT, mortality was 100% by 28 days. CONCLUSIONS Assessment of ACLF patients at 3-7 days of the syndrome provides a tool to define the emergency of LT and a rational basis for intensive care discontinuation owing to futility.

This paper presents work done at Medical Minner Project on the TREC-2011 Medical Records Track. The paper proposes four models for medical information retrieval based on Lucene index approach. Our retrieval engine used an Lucen Index scheme with traditional stopping and stemming, enhanced with entity recognition software on query terms. Our aim in this first competition is to set a broader project that involves the develop of a configurable Apache Lucene-based framework that allows the rapid development of medical search facilities. Results around the track median have been achieved. In this exploratory track, we think that these results are a good beginning and encourage us for future developments.
