    Durante los últimos años, la investigación educativa ha arrojado resultados positivos acerca de la utilización de enfoques de enseñanza STEM integrados para abordar el estudio de las ciencias de manera holística y contextualizada. Sin embargo, a pesar de estos resultados, la aplicación real de estos enfoques en las aulas escolares es puntual. Con el objetivo de revertir esta situación, este trabajo, enmarcado dentro del proyecto europeo botSTEM, busca favorecer la aplicación de enfoques de enseñanza STEM integrados en educación infantil, a través de la colaboración activa con los maestros y maestras en el diseño e implementación de secuencias didácticas STEM, gracias a la utilización de la Teoría de la Variación. Este objetivo será abordado a través de la presentación de un estudio preliminar de carácter cualitativo y cuyos resultados han permitido plantear el diseño de un futuro estudio interrumpido por la crisis sanitaria del COVID-19

    Presentamos el caso de una probable neurotoxicidad inducida por cefepima en una mujer pluripatológica de 82 años. La pacienteingresa en nuestro hospital por un aflojamiento séptico de prótesis de rodilla requiriendo un recambio de la misma. Treinta días después,la paciente es re-intervenida por presentar mala evolución clínica y se le inicia antibioticoterapia empírica con cefepima 2gcada 12 horas. A los tres días, se observa un cuadro de desorientación, agitación, afasia mixta, hemiplejia y presencia de movimientostónico-clónicos, juntamente con un deterioro de la función renal. Se sospecha de neurotoxicidad inducida por cefepima y se retiracon recuperación total a las 72 horas

    Sex and gender differences in acute stroke care: metrics, access to treatment and outcome. A territorial analysis of the Stroke Code System of Catalonia

    Introduction: Previous studies have reported differences in the management and outcome of women stroke patients in comparison with men. We aim to analyze sex and gender differences in the medical assistance, access to treatment and outcome of acute stroke patients in Catalonia. Patients and methods: Data were obtained from a prospective population-based registry of stroke code activations in Catalonia (CICAT) from January/2016 to December/2019. The registry includes demographic data, stroke severity, stroke subtype, reperfusion therapy, and time workflow. Centralized clinical outcome at 90 days was assessed in patients receiving reperfusion therapy. Results: A total of 23,371 stroke code activations were registered (54% men, 46% women). No differences in prehospital time metrics were observed. Women more frequently had a final diagnosis of stroke mimic, were older and had a previous worse functional situation. Among ischemic stroke patients, women had higher stroke severity and more frequently presented proximal large vessel occlusion. Women received more frequently reperfusion therapy (48.2% vs 43.1%, p < 0.001). Women tended to present a worse outcome at 90 days, especially for the group receiving only IVT (good outcome 56.7% vs 63.8%; p < 0.001), but not for the group of patients treated with IVT + MT or MT alone, although sex was not independently associated with clinical outcome in logistic regression analysis (OR 1.07; 95% CI, 0.94–1.23; p = 0.27) nor in the analysis after matching using the propensity score (OR 1.09; 95% CI, 0.97–1.22). Discussion and conclusion: We found some differences by sex in that acute stroke was more frequent in older women and the stroke severity was higher. We found no differences in medical assistance times, access to reperfusion treatment and early complications. Worse clinical outcome at 90 days in women was conditioned by stroke severity and older age, but not by sex itself

    Effectiveness of thrombectomy in stroke according to baseline prognostic factors: inverse probability of treatment weighting analysis of a population-based registry

    Background and Purpose In real-world practice, the benefit of mechanical thrombectomy (MT) is uncertain in stroke patients with very favorable or poor prognostic profiles at baseline. We studied the effectiveness of MT versus medical treatment stratifying by different baseline prognostic factors. Methods Retrospective analysis of 2,588 patients with an ischemic stroke due to large vessel occlusion nested in the population-based registry of stroke code activations in Catalonia from January 2017 to June 2019. The effect of MT on good functional outcome (modified Rankin Score ≤2) and survival at 3 months was studied using inverse probability of treatment weighting (IPTW) analysis in three pre-defined baseline prognostic groups: poor (if pre-stroke disability, age >85 years, National Institutes of Health Stroke Scale [NIHSS] >25, time from onset >6 hours, Alberta Stroke Program Early CT Score 3), good (if NIHSS <6 or distal occlusion, in the absence of poor prognostic factors), or reference (not meeting other groups’ criteria). Results Patients receiving MT (n=1,996, 77%) were younger, had less pre-stroke disability, and received systemic thrombolysis less frequently. These differences were balanced after the IPTW stratified by prognosis. MT was associated with good functional outcome in the reference (odds ratio [OR], 2.9; 95% confidence interval [CI], 2.0 to 4.4), and especially in the poor baseline prognostic stratum (OR, 3.9; 95% CI, 2.6 to 5.9), but not in the good prognostic stratum. MT was associated with survival only in the poor prognostic stratum (OR, 2.6; 95% CI, 2.0 to 3.3). Conclusions Despite their worse overall outcomes, the impact of thrombectomy over medical management was more substantial in patients with poorer baseline prognostic factors than patients with good prognostic factors

    Sovereign bond spreads determinants in Latin American countries: Before and during the XXI financial crisis

    10.1016/j.ememar.2013.08.004This paper aims to identify the main determinants of sovereign bond spreads in seven Latin American countries and verify the existence of contagion effect over these markets during the last financial crisis. We apply a panel data framework and find that the inflation, terms of trade ratio and the external debt and international reserves (both as percentage of GDP) are key drivers of sovereign bond spreads. Moreover, we test the crisis impact over emerging economies. Our results show that the crisis has a statistically significant impact on the EMBIG spreads since 2008
