    El presente estudio se desarrolla durante el segundo cuatrimestre del curso académico 2008-09, y tiene su origen en el planteamiento del uso socio-pedagógico de los blogs como recurso educativo en la asignatura Didáctica General, impartida en la Facultad de Formación del Profesorado de la Universidad de Extremadura. El estudio se fundamenta a través de diversos objetivos, los cuales guiaron la investigación llevada a cabo, y de los cuales podríamos destacar algunos como, conocer una herramienta social relacionada con la tecnología web 2.0, adquirir las competencias necesarias para el manejo de los blogs como recurso didáctico en el desarrollo académico y profesional de los futuros estudiantes, capacidad para expresar y difundir las ideas previas sobre el concepto de Didáctica a través de una aplicación del software social, fomentar el papel activo del discente, crear comunidades de conocimientos compartidos, y por último, elaborar un repositorio (básico) de unidades didácticas para futuras promociones académicas. A través de una metodología de corte cualitativa y descriptiva, el estudio permite llegar a diferentes conclusiones en lo que respecta a la incorporación de los blogs como herramienta didáctica en las aulas universitarias. Por ejemplo, reafirmar por parte de los estudiantes que los blogs son fáciles de elaborar y utilizar, favorecen la expresión de sus ideas y pensamientos, potencian la creación de comunidades de conocimientos, y que su utilización en el contexto universitario es una práctica adecuada y útil

    El estudio presentado tiene su origen en el planteamiento del uso socio-pedagógico de los blogs como recurso educativo en la asignatura Didáctica General, impartida en la Facultad de Formación del Profesorado de la Universidad de Extremadura. Esta investigación pretende que los estudiantes aprendan a utilizar los cuadernos de bitácoras (blogs) como recursos didácticos para la formación de futuros profesionales de la educación, de modo que cada estudiante se convierta en agente activo de su proceso de construcción del conocimiento, realizar una aproximación conceptual al término de unidad didáctica y elaborar un repositorio de éstas.MurciaUniversidad de Murcia, Facultad de Educación; Campus Universitario de Espinardo; 30100 Murcia; +34968364019; +34968364146; [email protected]

    Therapeutically-induced stable disease in oncology early clinical trials.

    RATIONALE:The RECIST guideline defines four categories of response to treatment for cancer patients according to post-baseline changes in tumor burden, hence ignoring disease history. However, if left untreated, tumors grow exponentially, implying that pretreatment changes in tumor size are key to thoroughly assess efficacy. We present a model-based approach to estimate the rates of changes in tumor mass, before and after treatment onset. METHODS:Sixty-eight patients were eligible for the analysis of tumor size data from a Phase 1 study evaluating the effect of emactuzumab. In addition to tumor size measured at baseline and every six weeks during treatment, a pre-baseline measurement was gathered for each patient. A longitudinal regression model was used to estimate the rates of tumor size change before and after treatment onset. RESULTS:The median pre-treatment tumor growth exponential rate was equal to 0.022 month-1, corresponding to a tumor size doubling time of 4 months, and the on-treatment median tumor shrinkage exponential rate was equal to 0.001 month-1. Among sixteen patients categorized as stable disease per RECIST, only five had similar slopes before and after treatment while nine actually improved. One patient in particular had a therapeutically induced stabilization of the disease. CONCLUSION:Our analysis emphasizes the importance of collecting pre-baseline scans to distinguish therapeutically induced stable disease from cases where the tumor growth is not perturbed by treatment

    Dalcetrapib, a cholesteryl ester transfer protein modulator, under development to increase high-density lipoprotein cholesterol and potentially decrease cardiovascular risk, will potentially be co-prescribed to women on oral contraceptive (OC). Objective: Assess the effect of dalcetrapib on the pharmacokinetics and ability to suppress ovulation of Microgynon® 30, a representative monophasic OC. Materials and methods: A single-center, randomized, open-label, two-period crossover study in healthy women receiving monophasic OC. Subjects received Microgynon® 30 (ethinylestradiol 0.03 mg/levonorgestrel 0.15 mg) once daily for 21 days followed by 7 treatment-free days (run-in period), then were randomized to Microgynon® 30 daily for 21 days with or without dalcetrapib 900 mg daily for Day 1 - 14. Plasma ethinylestradiol and levonorgestrel were measured on Day 14, and luteinizing hormone, follicle stimulating hormone, progesterone and estrogen from Day 11 - 14. The primary endpoint plasma exposure (AUC 0-24and C max) on Day 14 was evaluated for ethinylestradiol and levonorgestrel. Safety was monitored throughout. Results: 30 subjects were randomized. The exposure of ethinylestradiol and levonorgestrel was similar when Microgynon® 30 was administered with or without dalcetrapib; for ethinylestradiol the geometric mean ratio %, (90% confidence interval (CI)) for AUC0-24 and C max were 92 (86 - 98) and 105 (95 - 115) and for levonorgestrel 92 (88 - 96) and 93 (87 - 99), respectively. Concentrations of luteinizing hormone, follicle stimulating hormone, estrogen and progesterone were comparable between treatments. Conclusions: Dalcetrapib has no clinically relevant effect on the pharmacokinetics of ethinylestradiol and levonorgestrel. Contraceptive efficacy of Microgynon® 30 is not anticipated to be compromised by co-administration of dalcetrapib. ©2012 Dustri-Verlag Dr. K. Feistle
