Les projets bilingues et la méthodologie EMILE dans l´enseignement bilingue en Aragon. Vers un enseignement bilingue effectif

Hablar una lengua extranjera hoy en día es una necesidad.Los gobiernos de los paises se han visto en la necesidad de crear programas bilingues en las escuelas. Estos proyectos bilingues son diferentes en todos los paises y segun el contexto de enseñanza pero todos tienen en común la enseñanza de otras asignaturas en lengua extranjera, las que llamamos AELEX. En este trabajo vamos a analizar como las asignauras AELEX se enseñan, el modelo y cuales son los procesos a tener en cuenta para que el alumnado adquiera los contenidos en lengua extranjera.

Coronariografía por tomografía computarizada de doble fuente

La tomografía computarizada multicorte (TCMC) permite estudiar las arterias coronarias de forma no invasiva. A pesar de la elevada resolución espacial y temporal de los equipos de sesenta y cuatro cortes (TCMC- 64) esta técnica no se encuentra exenta de limitaciones. La tomografía computarizada de doble fuente (TCDF) permite estudiar las arterias coronarias con gran calidad diagnóstica en todos los sujetos independien- temente de su frecuencia cardiaca sin necesidad, por tanto, de emplear betabloqueantes. En este trabajo se describen los estudios por TCDF de tres pacientes con elevada frecuencia cardiaca y gran variabilidad del ritmo. Se demuestra la utilidad de esta técnica para obtener estudios de excelente calidad diagnóstica en casos en que la coronariografía por TCMC-64 convencional presenta limitaciones. INGLÉS: Multidetector computed tomography (MDCT) has been demonstrated to be a very useful technique to non-invasively study coronary arteries. Despite the high spatial and temporal resolution of 64-slice MDCT scanners, this technique has several limitations. Dual-source computed tomography (DSCT) allows to study coronary arteries with excellent diagnostic quality in all subjects independent of the heart rate, thus avoiding the use of beta-blockers. In this article DSCT studies from three subjects with elevated heart rate and irregular heart rhythm are described. Usefulness of this technique to obtain studies of excellent quality in cases in which conventional 64-row-MDCT might present limitations is emphasized

Valoración global del corazón en el paciente con transplante cardiaco mediante tomografía computarizada de doble fuente

In routine clinical practice surveillance of heart transplant recipients is usually performed using echocardiography and conventional coronary angiography. The latter permits diagnosis and follow-up of coronary allograft vasculopathy. However, this procedure is invasive and is not free of complications. Conventional multislice computed tomography (MSCT) has been shown to be a useful non-invasive tool for ruling out coronary artery disease and evaluating cardiac function. However, due to its limited temporal resolution betablocker administration is required, and its usefulness in certain patient populations with restricted response to this medication, such as heart transplant recipients, may therefore be limited. Dual-source CT (DSCT) allows evaluation of the coronary arteries in all individuals independent of their heart rate. In the case presented here, we demonstrate that DSCT may be useful for evaluating cardiac function and ruling out coronary allograft vasculopathy in heart transplant recipients

Miocarditis aguda: diagnóstico mediante resonancia magnética cardiaca

Cardiomyopathies are a common cause of morbidity and mortality. Myocarditis, which is included among specific cardiomyopathies, frequently presents non-specific clinical manifestations and thus may be difficult to diagnose, or even be misdiagnosed. Traditionally employed diagnostic techniques, including endomyocardial biopsy, have been shown to be of limited value. Following its overall implantation in clinical practice, cardiac magnetic resonance imaging (MRI) is nowadays widely considered to be the best non-invasive diagnostic tool available for diagnosing myocarditi

Dual-source CT for visualization of the coronary arteries in heart transplant patients with high heart rates

OBJECTIVE. The purpose of this study was to evaluate the quality of dual-source CT images of the coronary arteries in heart transplant recipients with high heart rates. SUBJECTS AND METHODS. Contrast-enhanced dual-source CT coronary angiography was performed on 23 heart transplant recipients (20 men, three women; mean age, 61.1 ± 12.8 years). Data sets were reconstructed in 5% steps from 30% to 80% of the R-R interval. Two blinded independent readers using a 5-point scale (0, not evaluative; 4, excellent quality) assessed the quality of images of coronary segments. RESULTS. The mean heart rate during scanning was 89.2 ± 10.4 beats/min. Interobserver agreement on the quality of images of the whole coronary tree was a kappa value of 0.78 and for selection of the optimal reconstruction interval was a kappa value of 0.82. The optimal reconstruction interval was systole in 17 (74%) of the 23 of heart transplant recipients. At the best reconstruction interval, diagnostic image quality (score ≥ 2) was obtained in 92.1% (303 of 329) of the coronary artery segments. The mean image quality score for the whole coronary tree was 3.1 ± 1.01. No significant correlation between mean heart rate (ρ = 0.31) or heart rate variability (ρ = 0.23) and overall image quality score was observed (p = not significant). CONCLUSION. Dual-source CT acquisition yields coronary angiograms of diagnostic quality in heart transplant recipients. Mean heart rate and heart rate variability during scanning do not have a negative effect on the overall quality of images of the coronary arteries

Análisis del riesgo kárstico en medios urbanos asentados sobre depósitos aluviales cementados (mallacán) en la Cuenca del Ebro (España)

Los procesos kársticos en medios urbanos pueden representar un riesgo significativo para la seguridad vial y constructiva. En este trabajo se presenta un estudio integrado de prospección geofísica, análisis superficial y ensayos mecánicos. Se identifica y delimita un dispositivo geométrico de tipo colapso y se aprecia que el mayor riesgo repentino se asocia a sectores marginales del colapso que presenta una orla de cavidades en el subsuelo. Los ensayos geomecánicos muestran una alta compacidad de los materiales naturales parcialmente cementados, lo que podría tomarse como indicador de estabilidad. En realidad, esta compacidad permite el sostenimiento inestable de cavidades propagadas desde el substrato hasta cerca de la superficie, siendo éste el mayor riesgo que aquí se trata de valorar. Active karst processes in urban settings can represent a significative hazard for the population and to buildings and other facilities. In this work, an integrated analysis by means of geophysical survey, surficial analysis and geomechanical tests is presented. The obtained results permit to identify a collapsed geometry where the more sudden hazards are related to the noncollapsed marginal areas of the sinkhole. The geomechanical tests show a high alluvial resistance due to the partial carbonatic cementation with apparent higher stability. However, cementation allows the individualization and the propagation of underground cavities up to near-surface levels being the highest hazard to be analyzed in these contexts

Familias y Docentes: garantes del aprendizaje durante el confinamiento = Families and teachers: guarantees of learning during confinement

p. 353-370El cierre de los centros educativos en España ha supuesto una adaptación inmediata sobre la forma de garantizar el aprendizaje. Los docentes han tenido que adaptarse de manera inmediata a un entorno digital de enseñanza y las familias han debido de atender con garantías a las tareas virtuales de sus hijos. El presente estudio tiene dos objetivos: a) analizar las variables relativas a la relación existente entre la familia, los centros educativos y los docentes, así como sus problemas para apoyar a los alumnos; b) analizar el efecto que tiene el modelo de enseñanza empleado por el docente en el seguimiento de la enseñanza virtual. Se ha utilizado una metodología cuantitativa con un diseño ex post facto descriptivo por encuesta, en el que han participado 3700 docentes y 5867 familias de todo el territorio español. Las principales dificultades se han encontrado en la falta de apoyo por parte de la administración y en la formación en competencia digital del profesorado. También ha quedado de manifiesto la necesidad de trabajar la autonomía y la autorregulación de los estudiantes y además existieron deferencias significativas en función del modelo de enseñanza (centrado en contenido versus en competencia) de los docentes.S

Detection of active hepatitis C in a single visit and linkage to care among marginalized people using a mobile unit in Madrid, Spain

Background: The burden of hepatitis C virus (HCV) infection among marginalized people in Spain is high, despite the fact that HCV prevalence has decreased in recent years. We aimed to assess the effectiveness of a simplified point-of-care (PoC) model for screening for active HCV infection via a mobile unit and subsequent linkage to care with the assistance of navigators. Methods: We carried out a prospective study on 2001 participants from Madrid, Spain. A nurse and a navigator/educator screened for hepatitis C in a mobile unit, using the OraQuick HCV Rapid Antibody Test and Xpert HCV VL Fingerstick assay. Participants with active HCV were referred to the hospital the same day with a navigator for evaluation and treatment of HCV. Results: Overall, 1621 (81%) participants had not been exposed to HCV, 380 (18.9%) were positive for HCV antibodies, and 136 (6.8%) had active hepatitis C. Among the latter, 134 (98.5%) received the HCV screening results, 133 (97.8%) had an appointment at the hospital, 126 (92.8%) were seen by a physician once they were at the hospital, and 105 (77.2%) started HCV treatment. Being over 50 years old and a person who uses drugs, particularly people who inject drugs (PWID), was directly associated with active hepatitis C (p<0.05). PWID were the only patients with HCV reinfection (4.3% in people without recent injecting drug use and 5.9% in people with recent injecting drug use). Among PWID, no income and daily alcohol intake were also directly associated with active hepatitis C. People with recent injecting drug use showed the lowest rates of attendance at the hospital (91.8%) and starting HCV treatment (70.4%). Conclusion: HCV screening using a two-step PoC-based strategy and its linkage to care was extremely efficient for identifying and treating marginalized people with active hepatitis C, thanks to the use of a mobile unit with personnel and technical equipment, an interdisciplinary team, and collaboration between institutions.This work was funded by a research grant from Gilead Science (IN-ES-987-5391 and GLD20_0144) and Instituto de Salud Carlos III (ISCII; grant numbers PI20CIII/00004 and RD16CIII/0002/0002 to SR).
