Encuesta de evaluación de la "usabilidad" de la sede web de la Biblioteca Universitaria de Córdoba

Comunicación presentada a las XV Jornadas Bibliotecarias de Andalucía: Bibliotecas, rompiendo barreras, tejiendo redes. Córdoba, 15-17, Octubre, 2009La unión cada vez más estrecha entre la biblioteca universitaria y su sede web es incuestionable. Este trabajo es un estudio de usabilidad de la sede web de la Biblioteca Universitaria de Córdoba. El estudio se ha llevado a cabo realizando una encuesta de evaluación entre dos grupos de usuarios/alumnos, con dos ediciones sucesivas de la página, y un tercer grupo de usuarios/expertos, con la última edición. Los resultados obtenidos muestran considerables diferencias en la forma de interactuar con el sitio web entre los dos primeros grupos de usuarios con respecto al tercero. El estudio de usabilidad ha sido una herramienta muy útil que, además, nos permitirá desarrollar futuras mejoras del sitio web que cumplan con las necesidades y expectativas de los usuarios

Role of age and comorbidities in mortality of patients with infective endocarditis

[Purpose]: The aim of this study was to analyse the characteristics of patients with IE in three groups of age and to assess the ability of age and the Charlson Comorbidity Index (CCI) to predict mortality. [Methods]: Prospective cohort study of all patients with IE included in the GAMES Spanish database between 2008 and 2015.Patients were stratified into three age groups:<65 years,65 to 80 years,and ≥ 80 years.The area under the receiver-operating characteristic (AUROC) curve was calculated to quantify the diagnostic accuracy of the CCI to predict mortality risk. [Results]: A total of 3120 patients with IE (1327 < 65 years;1291 65-80 years;502 ≥ 80 years) were enrolled.Fever and heart failure were the most common presentations of IE, with no differences among age groups.Patients ≥80 years who underwent surgery were significantly lower compared with other age groups (14.3%,65 years; 20.5%,65-79 years; 31.3%,≥80 years). In-hospital mortality was lower in the <65-year group (20.3%,<65 years;30.1%,65-79 years;34.7%,≥80 years;p < 0.001) as well as 1-year mortality (3.2%, <65 years; 5.5%, 65-80 years;7.6%,≥80 years; p = 0.003).Independent predictors of mortality were age ≥ 80 years (hazard ratio [HR]:2.78;95% confidence interval [CI]:2.32–3.34), CCI ≥ 3 (HR:1.62; 95% CI:1.39–1.88),and non-performed surgery (HR:1.64;95% CI:11.16–1.58).When the three age groups were compared,the AUROC curve for CCI was significantly larger for patients aged <65 years(p < 0.001) for both in-hospital and 1-year mortality. [Conclusion]: There were no differences in the clinical presentation of IE between the groups. Age ≥ 80 years, high comorbidity (measured by CCI),and non-performance of surgery were independent predictors of mortality in patients with IE.CCI could help to identify those patients with IE and surgical indication who present a lower risk of in-hospital and 1-year mortality after surgery, especially in the <65-year group

El derecho a los derechos : infancias y adolescencias en Cuba

«El derecho a los derechos. Infancias y adolescencias en Cuba», constituye un título atractivo y seductor, en el que se ofrece al lector una mirada crítica a retos, problemáticas y cuestiones teórico-prácticas en la protección integral de los niños, niñas y adolescentes. Profesionalidad, originalidad, impronta y opinión personal de cada uno de los autores signaron la concepción del libro. De igual forma, un lenguaje apropiado que se sustrae de tecnicismos barrocos y excesivos para facilitar la lectura. Es una obra pensada desde la academia para impactar la realidad social. (...) engrosa los estudios sobre infancia y adolescencia existentes, es expresión de un saber especializado, tanto a nivel de la investigación científica como de la práctica y la gestión institucional estatal y de la sociedad civil. No busca ser meta, punto de llegada, al contrario, es una propuesta que invita permanentemente al debate, la discusión teórica, la reflexión, al examen de las formas de hacer y al pensamiento crítico.

Contemporary use of cefazolin for MSSA infective endocarditis: analysis of a national prospective cohort

Objectives: This study aimed to assess the real use of cefazolin for methicillin-susceptible Staphylococcus aureus (MSSA) infective endocarditis (IE) in the Spanish National Endocarditis Database (GAMES) and to compare it with antistaphylococcal penicillin (ASP). Methods: Prospective cohort study with retrospective analysis of a cohort of MSSA IE treated with cloxacillin and/or cefazolin. Outcomes assessed were relapse; intra-hospital, overall, and endocarditis-related mortality; and adverse events. Risk of renal toxicity with each treatment was evaluated separately. Results: We included 631 IE episodes caused by MSSA treated with cloxacillin and/or cefazolin. Antibiotic treatment was cloxacillin, cefazolin, or both in 537 (85%), 57 (9%), and 37 (6%) episodes, respectively. Patients treated with cefazolin had significantly higher rates of comorbidities (median Charlson Index 7, P <0.01) and previous renal failure (57.9%, P <0.01). Patients treated with cloxacillin presented higher rates of septic shock (25%, P = 0.033) and new-onset or worsening renal failure (47.3%, P = 0.024) with significantly higher rates of in-hospital mortality (38.5%, P = 0.017). One-year IE-related mortality and rate of relapses were similar between treatment groups. None of the treatments were identified as risk or protective factors. Conclusion: Our results suggest that cefazolin is a valuable option for the treatment of MSSA IE, without differences in 1-year mortality or relapses compared with cloxacillin, and might be considered equally effective
