Doce años después.... recuperamos el saber acumulado y elaboramos una nueva propuesta docente para los estudiantes de Tecnología educativa de la Universidad de Barcelona

En este artículo se relatan los cambios introducidos en nuestra propuesta docente de la asignatura de Tecnología Educativa en la Universidad de Barcelona y se intenta mostrar el trabajo, el conocimiento y el saber acumulado en todos estos años. El texto se divide en dos bloques. El primero, describe la propuesta actual y el recorrido realizado desde el curso 1993/94. Es una síntesis – con las limitaciones que conlleva – donde se destaca el sentido y algunos cambios significativos para las profesoras y profesores de la asignatura, en su intento de alejarse de una práctica docente de tradición reproductora, que la mayoría de las alumnas y los alumnos habían experimentado en propuestas educativas anteriores. El segundo, recoge algunas de sus voces y nos muestra como se han apropiado y han significado el trabajo realizado durante este curso 2004/05. La valoración de los alumnos y alumnas, es un mosaico de testimonios que nos permite comprender o, al menos, intuir el sentido que ha podido tener para ellas y ellos esta vivencia. Algunos de éstos son reveladores en cuanto confirman o desmienten tópicos o creencias, asumidas por el profesorado, y por mostrar elementos sutiles que quizás durante las sesiones de clase pasaron desapercibidos.In this article we describe the changes introduced in our educational proposal of the subject of Educational Technology in the University of Barcelona and we show the work and the knowledge accumulated in every year. The text is divided in two blocks. The first one, describes the current proposal and the journey carried out from the course 1993/94. It is a synthesis, where he/she stands out the sense and some significant changes for the teachers of the subject, in their intent of moving away from an educational practice of reproductional tradition that most of the students had experienced in previous educational proposals. The second, it picks up some of their voices and it shows us like they have appropriated and they have meant the work carried out during this course 2004/05. The valuation of the students, it is a mosaic of testimonies that allows us to understand this experience

Recognition and activation of the plant AkT1 potassium channel by the kinase CIPK23

Plant growth largely depends on the maintenance of adequate intracellular levels of potassium (K1). The families of 10 Calcineurin B-Like (CBL) calcium sensors and 26 CBL-Interacting Protein Kinases (CIPKs) of Arabidopsis (Arabidopsis thaliana) decode the calcium signals elicited by environmental inputs to regulate different ion channels and transporters involved in the control of K1 fluxes by phosphorylation-dependent and -independent events. However, the detailed molecular mechanisms governing target specificity require investigation. Here, we show that the physical interaction between CIPK23 and the noncanonical ankyrin domain in the cytosolic side of the inward-rectifier K1 channel AKT1 regulates kinase docking and channel activation. Point mutations on this domain specifically alter binding to CIPK23, enhancing or impairing the ability of CIPK23 to regulate channel activity. Our data demonstrate the relevance of this protein–protein interaction that contributes to the formation of a complex between CIPK23/CBL1 and AKT1 in the membrane for the proper regulation of K1 transport

Differential clinicopathological and molecular features within late-onset colorectal cancer according to tumor location

Background: Since there is a predilection of some clinical and molecular features for a given tumor location, we assessed whether this can be confirmed in late-onset colorectal cancer (LOCRC). Results: Right colon cancers showed features associated with sporadic Microsatellite Instability: predominance of female cases and BRAF mutations, and an important mucinous component. Left colon cancers developed a higher number of polyps and multiple primary CRCs, showed the strongest familial component, and had better prognosis. Rectal cancers showed a predominantly sporadic phenotype, with worse prognosis and a CpG Island Methylator Phenotype (CIMP)-High. No copy number alterations (CNAs) greater than or equal to 50% were observed in this LOCRC group, and the most recurrent alterations were losses at 5q13 and 14q11, and gains at 7q11, 7q21-q22, 19p13-p12, 19q13 and 20p11-q11. KRAS and PIK3CA were the only mutated genes showing differences according to the tumor location, mainly for right colon cancers. Materials and Methods: We analyzed clinical and molecular characteristics of LOCRC at different tumor locations in order to determine if there are differential phenotypes related with the location in the colon. Conclusions: Categorizing LOCRC according to tumor location appears to be an adequate first step to resolving the heterogeneity of this subset of CRCThis work was funded by Projects PI10/0683, PI13/01741, PI13/0127 and PI14/00459 from the Spanish Ministry of Health and Consumer Affairs and FEDER, and was approved by the Ethics Committee of our Institutio

Lung cancer in Spain: information from the Thoracic Tumors Registry (TTR study)

[Background] Lung cancer remains a leading cause of cancer incidence and mortality worldwide. Although Spain contributes to global statistics related to cancer, it is difficult to discern aspects linked to clinical presentation of the disease or molecular testing. The Thoracic Tumor Registry (TTR) was created with the aim of filling this gap.[Methods] Observational cohort multicenter study performed in Spain, including patients with lung cancer or other types of thoracic tumors undergoing active treatment or palliative care only. Enrollment took place between August 2016 and December 2018. The evaluation included a review of demographic, epidemiological, clinical and molecular data.[Results] A total of 6,600 patients diagnosed with non-small cell lung cancer (NSCLC) were recruited at 56 Spanish hospitals. The mean age at diagnosis was 64 years. The majority of patients (80%) presented with advanced disease, being adenocarcinoma the most frequent histological type. Up to 86% of patients were current- or ex-smokers, with men starting to smoke earlier than women (average age 17.9 vs. 19.2 years). Sixty-seven percent of patients underwent some type of molecular testing. Mutations in EGFR and KRAS genes were found in 18% and 28% of patients, respectively.[Conclusions] Our findings suggest that the TTR study accurately describes the clinical reality of lung cancer in Spain, including useful information on smoking status as well as molecular profiling and tumor histology, and can therefore be used to drive improvements in health care. Social and political pressure to reduce tobacco consumption among the population should be reinforced, particularly among youth.This work was supported by Grupo Español de Cáncer de Pulmón (GECP), Novartis, Lilly and Merck Sharp & Dohme (MSD)

Estudio cycEVA: casos y controles para la estimación de la efectividad de la vacuna antigripal en España, 2008-2013

Fundamentos: Desde 2008-09 la efectividad de la vacuna (EV) antigripal en España se estima con el estudio de casos y controles para la evaluación de la EV antigripal (cycEVA), componente español de la red europea (Influenza-Monitoring Vaccine Effectiveness (I-MOVE). El objetivo es describir la evolución del estudio cycEVA durante las cinco temporadas del período 2008/09– 2012/13. Métodos: Se analizaron los siguientes indicadores: 1) participación de los médicos/pediatras centinela (MP); 2) población y periodo de estudio, 3) calidad de los datos y 4) difusión de los resultados mediantes publicaciones. Se calculó el porcentaje anual de cambio constante de los indicadores analizándose su tendencia mediante el test de Cochran-Armitage. Resultados: El número de MP participantes aumentó de 164 en 2008-09 hasta 246 en ediciones posteriores. El porcentaje de médicos que reclutaron al menos un paciente experimentó un cambio anual significativo (PCA) del 15,33%. El porcentaje de pacientes reclutados incluidos en el análisis aumen- tó del 77% en 2008-09 a más del 95% en las siguientes ediciones (PCA=5,91%). El porcentaje de casos y controles participantes en cycEVA sobre el total de pacientes que contribuyeron al estudio europeo I-MOVE osciló entre el 23% en la edición piloto y 30% en la temporada 2011-12. Los resultados finales se difundieron en revistas científicas con un factor de impacto situado en el cuartil 2 y en 2010-11 y 2011-12 se publicaron resultados preliminares en revistas con un factor de impacto situado en el cuartil 1 (97 citas). Conclusiones: La experiencia del estudio cycEVA se reflejó en una mejora en la oportunidad e impacto de sus resultados, cruciales para orientar las recomendaciones anuales de vacunación antigripal

La convivencia en los centros educativos de educación básica en Iberoamérica

La presente aportación recoge la visión de 46 especialistas de quince países iberoamericanos sobre las formas de entender y promover la convivencia escolar en los centros educativos de los distintos países. Sus aportaciones son un conjunto de descripciones, experiencias y valoraciones significativas y en relación al contexto considerado. Las aportaciones no buscan tanto radiografiar la temática a nivel teórico como presentar lo más significativo de cada realidad y las propuestas que, al respecto, se realizan. La orientación es claramente organizativa, si consideramos que una parte común de todas las aportaciones tiene que ver con las políticas de convivencia escolar, programas aplicados, aspectos organizativos a nivel de institución, experiencias significativas y retos para la mejora. Se cubre así y de nuevo un propósito fundamental de la Red AGE, como es el de fomentar el intercambio de experiencias, la promoción del conocimiento sobre administración y gestión educativa y la reflexión sobre la práctica de la gestión. La finalidad última es la de mejorar el funcionamiento de los centros educativos (y, a través de ellos, de los sistemas educativos), procurando sean de calidad y un instrumento para el cambio profesional y social

Development and validation of a nomogram to predict kidney survival at baseline in patients with C3 glomerulopathy

10 p.-4 fig.-2 tab. 1 graph. abst.Background: C3 glomerulopathy is a rare and heterogeneous complement-driven disease. It is often challenging to accurately predict in clinical practice the individual kidney prognosis at baseline. We herein sought to develop and validate a prognostic nomogram to predict long-term kidney survival.Methods: We conducted a retrospective, multicenter observational cohort study in 35 nephrology departments belonging to the Spanish Group for the Study of Glomerular Diseases. The dataset was randomly divided into a training group (n = 87) and a validation group (n = 28). The least absolute shrinkage and selection operator (LASSO) regression was used to screen the main predictors of kidney outcome and to build the nomogram. The accuracy of the nomogram was assessed by discrimination and risk calibration in the training and validation sets.Results: The study group comprised 115 patients, of whom 46 (40%) reached kidney failure in a median follow-up of 49 months (range 24–112). No significant differences were observed in baseline estimated glomerular filtration rate (eGFR), proteinuria or total chronicity score of kidney biopsies, between patients in the training versus those in the validation set. The selected variables by LASSO were eGFR, proteinuria and total chronicity score. Based on a Cox model, a nomogram was developed for the prediction of kidney survival at 1, 2, 5 and 10 years from diagnosis. The C-index of the nomogram was 0.860 (95% confidence interval 0.834–0.887) and calibration plots showed optimal agreement between predicted and observed outcomes.Conclusions: We constructed and validated a practical nomogram with good discrimination and calibration to predict the risk of kidney failure in C3 glomerulopathy patients at 1, 2, 5 and 10 years.Work on this study was supported by the Instituto de Salud Carlos III / Fondo Europeo de Desarrollo Regional (ISCIII/FEDER; grants PI16/01685 and PI19/1624) and Red de Investigación Renal (RD12/0021/0029; to M.P.) and the Autonomous Region of Madrid (S2017/BMD-3673; to M.P.).
