[Es]El objetivo de esta investigación ha sido analizar la implicación o compromiso de nuestros estudiantes con sus centros escolares. La implicación posee un componente conductual (la participación) y un componente psicológico (la identificación con el centro escolar). La muestra está compuesta por 656 alumnos de 14 colegios del País Vasco y Cataluña, divididos según diferentes tipologías de centro: 179 en pública-primaria, 151 alumnos en concertada-primaria, 203 alumnos en pública¬-secundaria y 123 alumnos en concertada-secundaria. Los resultados indican que las percepciones en las escalas de participación e identificación son más altas en los centros concertados, de primaria y con una sola línea educativa y modelo lingüístico. Así mismo hemos comprobado que existen correlaciones entre las dos dimensiones de la implicación y las variables independientes analizadas: autoconcepto y motivación académica, tipología de centro, trabajo de los profesores y el entorno familiar.

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.

RESUMEN Introducción: La cirugía extracorpórea es el procedimiento quirúrgico torácico en la que se accede a las cavidades del corazón para realizar recambios valvulares, puentes cardiopulmonares y otras intervenciones. Se accede al mediastino mediante esternotomía. Una maquina asumirá la función del corazón, realizando la circulación extracorpórea mientras este es intervenido. El paciente será derivado a las unidades de cuidados intensivos, donde deberá ser controlado por el personal sanitario controlando los dispositivos y catéteres, disminuyendo las posibles complicaciones postoperatorias. Objetivo: Conocer las complicaciones postoperatorias de la cirugía extracorpórea, describir las complicaciones postoperatorias más habituales de la cirugía, analizar las variables con mayor influencia en esta cirugía y comparar los beneficios de la cirugía extracorpórea frente a la revascularización miocárdica sin cirugía extracorpórea, mediante el análisis de fuentes de datos. Material y métodos: Se ha realizado una búsqueda bibliográfica informatizada en las bases de datos Cuiden, Pubmed, Elservier, CSIC, Dialnet y Google Académico de fuentes de datos actuales sobre la cirugía extracorpórea, mediante unos criterios de inclusión y exclusión determinados. Está dividida en 3 partes: investigación, selección y extracción de datos. Resultados: Se han analizado 8 estudios. Se han dividido en diferentes grupos, la muestra de los estudios analizados va desde 11 pacientes hasta 18.252, midiendo variables de dolor, sangrado, reintervención y otras. Conclusiones: La complicación más frecuente en el postoperatorio es el dolor. Muchas de las complicaciones se dan habitualmente en las primeras 24 horas posteriores a la intervención. Tiene un índice de mortalidad bajo, pero es mayor que en la revascularización miocárdica sin cirugía extracorpórea.

The present corpus study aimed to examine whether Basque (OV) resorts more often than Spanish (VO) to certain grammatical operations, in order to minimi ze the number of arguments to be processed before the verb. Ueno & Polinsky (2009) argue that VO/OV languages use certain grammatical resources with different frequencies in order to facilitate real-time processing. They observe that both OV and VO languages in their sample (Japanese, Turkish and Spanish) have a similar frequency of use of subject pro-drop; however, they find that OV languages (Japanese, Turkish) use more intransitive sentences than VO languages (English, Spanish), and conclude this is an OV-specific strategy to facilitate processing. We conducted a comparative corpus study of Spanish (VO) and Basque (OV). Results show (a) that the fre- quency of use of subject pro-drop is higher in Basque than in Spanish; and (b) Basque does not use more intransitive sentences than Spanish; both languages have a similar frequency of intransitive sentences. Based on these findings, we conclude that the frequency of use of grammatical resources to facilitate the processing does not depend on a single typological trait (VO/OV) but it is modulated by the concurrence of other grammatical feature.
