Enseñanza de las ciencias : revista de investigación y experiencias didácticas
1993
Resumen basado en el de la publicación Resumen en inglés ¿La educación sanitaria es lo mismo que la educación para la salud? ¿Qué factores hay que tener en cuenta al configurar un plan de estudios para la educación de la salud? ¿Es necesario tratar asuntos de salud tales como higiene, vacunaciones, etc., para desarrollar este tipo de educación para las escuelas? Estas son solo algunas de las preguntas que se plantean y se muestra el uso de fuentes que determinan un plan de estudios, como en el caso específico de Alimentación-Nutrición. ESP

Inferencia Estadística (2010/11)
2010
Los contenidos de la materia , tras repasar y consolidar algunas cuestiones del cálculo de probabilidades , especialmente las distribuciones multivariantes y las derivadas de las distribución normal, se centran en los recursos teóricos fundamentales para resolver los dos problemas esenciales de la inferencia estadística: la estimación de parámetros y el contaste de hipótesis
Methodological analysis of the spanish production on doctoral thesis in mathematical education (1976-1998)
2004
This study shows a comprehensive vision of the Mathematics Education at methodological level, using as base the doctoral dissertations (thesis) accomplished in Spanish universities between the years 1976-1998. A central finding of this study has been the design of an evaluation methodological instrument, which will be useful for the future analysis of research. In addition general recommendations are offered with the aim to improve quality of the research in Mathematics Education.
Non-immune hydrops fetalis: Two case reports
2021
BACKGROUND Fetal hydrops is a serious condition difficult to manage, often with a poor prognosis, and it is characterized by the collection of fluid in the extravascular compartments. Before 1968, the most frequent cause was the maternal-fetal Rh incompatibility. Today, 90% of the cases are non-immune hydrops fetalis. Multiple fetal anatomic and functional disorders can cause non-immune hydrops fetalis and the pathogenesis is incompletely understood. Etiology varies from viral infections to heart disease, chromosomal abnormalities, hematological and autoimmune causes. CASE SUMMARY A 38-year-old pregnant woman has neck lymphoadenomegaly, fever, cough, tonsillar plaques at 14 wk of amenorrhea…
Reacciones de cicloadición formal enantioselectivas con isocianoacetatos
2020
En la presente tesis doctoral se ha llevado a cabo el estudio de la cicloadición formal [3+2] enantioselectiva de isocianoacetatos a diferentes electrófilos para la formación de nuevas estructuras cíclicas nitrogenadas. Para ello, se ha desarrollado un método catalítico cooperativo consistente en un organocatalizador bifuncional de tipo escuaramida y óxido de plata como ácido de Lewis. En el primer capítulo se ha estudiado la reacción de adición de isocianoacetatos a trifluoroacetofenonas para la obtención de 2-oxazolinas con dos centros estereogénicos consecutivos, siendo uno de ellos cuaternario y estando sustituido con un grupo trifluorometilo. Se ha estudiado el alcance y las limitacion…
Eye tracking and the translation process: reflections on the analysis and interpretation of eye-tracking data
2014
Eye tracking has become increasingly popular as a quantitative research method in translation research. This paper discusses some of the major methodological issues involved in the use of eye tracking in translation research. It focuses specifically on challenges in the analysis and interpretation of eye-tracking data as reflections of cognitive processes during translation. Four types of methodological issues are discussed in the paper. The first part discusses the preparatory steps that precede the actual recording of eye-tracking data. The second part examines critically the general assumptions linking eye movements to cognitive processing in the context of translation research. The thir…
Intravenous high-dose furosemide and hypertonic saline solutions for refractory heart failure and ascites.
2011
Several studies have shown the efficacy of hypertonic saline solution infusion in conditions in which regional organ blood flow is impaired. Our group has shown that treatment of patients with diuretic-resistant heart failure with high-dose furosemide plus hypertonic saline is effective and well tolerated, improving symptoms of congestion, reducing plasma levels of markers of neurohormonal and inflammatory activation, decreasing hospital readmission rates, and reducing long-term mortality. The same regimen was shown to be better than repeated paracentesis in patients with cirrhosis and refractory ascites, yielding better control of ascites, pleural effusions, and/or leg edema without an inc…
Assessing the impact of COVID-19 on the management of patients with liver diseases: A national survey by the Italian association for the study of the…
2020
Abstract Background The COVID-19 pandemic had a huge impact on national and regional health systems. The impact of SARS-CoV-2 on the quality of care for patients with liver disease is still unknown. Aims The Italian Association for the Study of the Liver (AISF) conducted a survey to assess the impact of SARS-CoV-2 on hepatology units activities in Italy. Methods A prospective web-based survey was proposed to all AISF active members. The survey was available online from April 8 2020, to May 3 2020, (lockdown phase in Italy). Results 194 AISF members answered the questionnaire, most of whom were specialists in Gastroenterology (41%) or Internal Medicine (28%), and worked in Northern Italy (51…
Immune-inflammatory and metabolic effects of high dose furosemide plus hypertonic saline solution (HSS) treatment in cirrhotic subjects with refracto…
2016
Introduction Patients with chronic liver diseases are usually thin as a result of hypermetabolism and malnutrition expressed by reduced levels of leptin and impairment of other adyponectins such as visfatin. Aims We evaluated the metabolic and inflammatory effects of intravenous high-dose furosemide plus hypertonic saline solutions (HSS) compared with repeated paracentesis and a standard oral diuretic schedule, in patients with cirrhosis and refractory ascites. Methods 59 consecutive cirrhotic patients with refractory ascites unresponsive to outpatient treatment. Enrolled subjects were randomized to treatment with intravenous infusion of furosemide (125-250mg⁄bid) plus small volumes of HSS …
