Eficacia escolar y pruebas PISA. Factores del éxito escolar

El proyecto de tesis doctoral que aquí se propone supone una continuación de los proyectos de investigación realizados previamente por el Grupo de Evaluación Educativa y Orientación (GE2O) integrante del Grupo Consolidado Grupo de Investigación en Interacción y eLearning (GRIAL) y del Instituto Universitario de Ciencias de la Educación de la Universidad de Salamanca (IUCE), al amparo de convocatorias nacionales para la financiación de proyectos de I+D desde el periodo 2007-2009 hasta la actualidad. Las pruebas estandarizadas como la que nos atañe, PISA, tienen como objetivo conocer la situación actual de los sistemas educativos en diferentes partes del mundo según sus diferentes características, las socioeconómicas entre ella

A multilevel investigation of factors related to achievement in Ireland and Spain using PISA data

The Program for International Assessment (PISA) is a methodology for making comparative judgments about the quality of education systems. Celebrated by proponents as a transparent process that allows policy makers produce data informed judgments about relative quality of their national education system PISA – and through it the OECD – has become a key vehicle for informing and explaining educational policy development. This paper explores the Irish and Spanish outcomes of the 2018 round of PISA. It examines the contextual factors that are associated with performance at student and school level while at the same time developing a multi-level statistical model to explain divergent school performance profiles It finds that issues associated with the socio-economic level of the students, the repetition rate, and student age are common across all domains in both countries. It suggests that the socio-economic status of Spanish students at school level is not significant, that the shortage of teachers in Ireland affects student performance, and that immigrant status does not disadvantage Spanish student performance. It concludes by suggesting that studies involving a wider application of the model be undertaken to assess possible social, economic, and cultural causes that may explain the differences in variable significance in each country

Use of eltrombopag for patients 65 years old or older with immune thrombocytopenia

Background Eltrombopag is useful for immune thrombocytopenia (ITP). However, results of clinical trials may not accurately mirror clinical practice reality. Here we evaluated eltrombopag for primary and secondary ITP in our ≥65‐year‐old population. Methods A total of 106 primary ITP patients (16 with newly diagnosed ITP, 16 with persistent ITP, and 74 with chronic ITP) and 39 secondary ITP patients (20 with ITP secondary to immune disorders, 7 with ITP secondary to infectious diseases, and 12 with ITP secondary to lymphoproliferative disorders [LPD]) were retrospectively evaluated. Results Median age of our cohort was 76 (interquartile range, IQR, 70‐81) years. 75.9% of patients yielded a platelet response including 66.2% complete responders. Median time to platelet response was 14 (IQR, 8‐21) days. Median time on response was 320 (IQR, 147‐526) days. Sixty‐three adverse events (AEs), mainly grade 1‐2, occurred. The most common were hepatobiliary laboratory abnormalities (HBLAs) and headaches. One transient ischemic attack in a newly diagnosed ITP and two self‐limited pulmonary embolisms in secondary ITP were the only thrombotic events observed. Conclusion Eltrombopag showed efficacy and safety in ITP patients aged ≥65 years with primary and secondary ITP. However, efficacy results in LPD‐ITP were poor. A relatively high number of deaths were observed

Growth hormone remodels the 3D-structure of the mitochondria of inflammatory macrophages and promotes metabolic reprogramming

IntroductionMacrophages are a heterogeneous population of innate immune cells that support tissue homeostasis through their involvement in tissue development and repair, and pathogen defense. Emerging data reveal that metabolism may control macrophage polarization and function and, conversely, phenotypic polarization may drive metabolic reprogramming.MethodsHere we use biochemical analysis, correlative cryogenic fluorescence microscopy and cryo-focused ion-beam scanning electron microscopy.ResultsWe demonstrate that growth hormone (GH) reprograms inflammatory GM-CSF-primed monocyte-derived macrophages (GM-MØ) by functioning as a metabolic modulator. We found that exogenous treatment of GM-MØ with recombinant human GH reduced glycolysis and lactate production to levels similar to those found in anti-inflammatory M-MØ. Moreover, GH treatment of GM-MØ augmented mitochondrial volume and altered mitochondrial dynamics, including the remodeling of the inner membrane to increase the density of cristae.ConclusionsOur data demonstrate that GH likely serves a modulatory role in the metabolism of inflammatory macrophages and suggest that metabolic reprogramming of macrophages should be considered as a new target to intervene in inflammatory diseases

Use of eltrombopag for secondary immune thrombocytopenia in clinical practice.

Eltrombopag is a second-line treatment in primary immune thrombocytopenia (ITP). However, its role in secondary ITP is unknown. We evaluated the efficacy and safety of eltrombopag in secondary ITP in daily clinical practice. Eighty-seven secondary ITP patients (46 with ITP secondary to autoimmune syndromes, 23 with ITP secondary to a neoplastic disease subtype: lymphoproliferative disorders [LPDs] and 18 with ITP secondary to viral infections) who had been treated with eltrombopag were retrospectively evaluated. Forty-four patients (38%) had a platelet response, including 40 (35%) with complete responses. Median time to platelet response was 15 days (95% confidence interval, 7-28 days), and was longer in the LPD-ITP group. Platelet response rate was significantly lower in the LPD-ITP than in other groups. However, having achieved response, there were no significant differences between the durable response of the groups. Forty-three patients (49·4%) experienced adverse events (mainly grade 1-2), the commonest being hepatobiliary laboratory abnormalities. There were 10 deaths in this case series, all of which were related to pre-existing medical conditions. In routine clinical practice, eltrombopag is effective and well-tolerated in unselected patients with ITP secondary to both immune and infectious disorders. However, the response rate in LPD-ITP is low

Patients awaiting surgery for neurosurgical diseases during the first wave of the COVID-19 pandemic in Spain: a multicentre cohort study.

The large number of infected patients requiring mechanical ventilation has led to the postponement of scheduled neurosurgical procedures during the first wave of the COVID-19 pandemic. The aims of this study were to investigate the factors that influence the decision to postpone scheduled neurosurgical procedures and to evaluate the effect of the restriction in scheduled surgery adopted to deal with the first outbreak of the COVID-19 pandemic in Spain on the outcome of patients awaiting surgery. This was an observational retrospective study. A tertiary-level multicentre study of neurosurgery activity between 1 March and 30 June 2020. A total of 680 patients awaiting any scheduled neurosurgical procedure were enrolled. 470 patients (69.1%) were awaiting surgery because of spine degenerative disease, 86 patients (12.6%) due to functional disorders, 58 patients (8.5%) due to brain or spine tumours, 25 patients (3.7%) due to cerebrospinal fluid (CSF) disorders and 17 patients (2.5%) due to cerebrovascular disease. The primary outcome was mortality due to any reason and any deterioration of the specific neurosurgical condition. Second, we analysed the rate of confirmed SARS-CoV-2 infection. More than one-quarter of patients experienced clinical or radiological deterioration. The rate of worsening was higher among patients with functional (39.5%) or CSF disorders (40%). Two patients died (0.4%) during the waiting period, both because of a concurrent disease. We performed a multivariate logistic regression analysis to determine independent covariates associated with maintaining the surgical indication. We found that community SARS-CoV-2 incidence (OR=1.011, p Patients awaiting neurosurgery experienced significant collateral damage even when they were considered for scheduled procedures

Métodos de innovación docente aplicados a los estudios de Ciencias de la Comunicación

Se analiza el fenómeno de la implantación del Espacio Europeo de Educación Superior (EEES) a los estudios de Ciencias de la Comunicación, desde el punto de vista del profesorado. En este sentido se analizan experiencias educativas como: cuadernos de visionado para la iniciación de los alumnos en el comentario fílmico; la utilización didáctica de recursos audiovisuales; el uso de películas como herramientas en la educación de estudiantes; el uso de la televisión informativa; y la aplicación de técnicas de aprendizaje colaborativo entre otras propuestas. Asimismo, se estudia el estado de implantación del EEES en España y se describen propuestas de aplicación del mismo a diferentes áreas de los estudios de Ciencias de la Comunicación. También se dedican estudios a la descripción de nuevas estrategias docentes en el marco del EEES y se proponen fórmulas de evaluación de los aprendizajes. Por último se presta atención a la aplicación de las Tecnologías de la Información y la Comunicación a los citados estudios y se definen nuevas herramientas para apoyar a los estudiantes en su labor.MadridBiblioteca de Educación del Ministerio de Educación, Cultura y Deporte; Calle San Agustín 5 -3 Planta; 28014 Madrid; Tel. +34917748000; [email protected]
