Engineering Final Project supervised in an adaptive way with Moodle support

For the current Engineering degrees, it’s necessary to design a monitoring process in order to supervise the subject called “Final Degree Project”. This method must be able to manage and evaluate the process of completing the project and submitting the documentation. This paper describes the design of an adaptive method and how to put this mechanism into practice using the learning management system Moodle. Adaptivity provides the chance to study different scenarios that can be produced in cooperation with students and their tutors. The conclusions of this work show a high level of satisfaction with the adaptive method used in the subject

The learning improvement of engineering students using peer-created complementary resources

In any organization, the individual is considered an issuer of knowledge who can improve corporate knowledge, and learning is considered to be a key factor in promoting the creation of knowledge. As the knowledge of the individual increases, the organization''s knowledge also increases. The same happens in educational institutions, but there is a tendencyinmost educational methodologies to consider the studentasamere recipient of knowledge. Thispaper presents a model where the student is shown as a knowledge issuer both for their own benefit and for their peers. The key idea is the transfer of knowledge produced by students to organizational knowledge through the knowledge management system the Collaborative Academic Resources Finder (BRACO, for its acronym in Spanish). At the same time, certain quantitative measurement instruments provide insight into student perception of the use of this knowledge in a particular subject in their engineering degree studies as well as the measure of BRACO impact on their learning outcomes. The results of this workshow that an experimental group obtained higher scores in tests than a control group. Results alsoshow that BRACO had a significant impact on learning, and students promoted, organized and used the resources generated by fellow students

Pilot test for validation of an instrument of Knowledge management in the massive open online context

Knowledge management is a systematic process that deals with looking for, filtering, introducing and using information with the support of information technologies. The objective of using knowledge management depends on the sector that uses it. In companies, it is a value in the balance, in education it is a way to improve the successful of students. The massive open online courses (MOOC) are a topic in which it has been done little researching into the area of knowledge management. In this work, it will be presented a measurement instrument of knowledge management processes on MOOC. The model is based on a previous model used in business who has been adapted to the intercultural, massive and informal context of MOOC. The model was made with the help of an expert panel and its internal consistence was assessing with the Alpha Cronbach technique obtaining general scores over 0.9

Active surveillance in prostate cancer: role of available biomarkers in daily practice

Prostate cancer (PCa) is the most commonly diagnosed cancer in men. The diagnosis is currently based on PSA levels, which are associated with overdiagnosis and overtreatment. Moreover, most PCas are localized tumours; hence, many patients with low-/very low-risk PCa could benefit from active surveillance (AS) programs instead of more aggressive, active treatments. Heterogeneity within inclusion criteria and follow-up strategies are the main controversial issues that AS presently faces. Many biomarkers are currently under investigation in this setting; however, none has yet demonstrated enough diagnostic ability as an independent predictor of pathological or clinical progression. This work aims to review the currently available literature on tissue, blood and urine biomarkers validated in clinical practice for the management of AS patients

Variabilidad dentro del Registro Nacional multicéntrico en Vigilancia Activa; cuestionario a urólogos

Introducción: Nuestro objetivo principal es describir la utilización actual en España de la vigilancia activa (VA) identificando áreas de potencial mejora. Métodos: Un cuestionario generado en AEU/PIEM/2014/0001 (NCT02865330) fue remitido a todos los investigadores asociados (IA) durante los meses de enero-marzo del 2016. Incluía 7 dominios diferentes cubriendo diferentes aspectos en VA. Resultados: Treinta y tres de cuarenta y un IA respondieron el cuestionario. La VA es principalmente controlada por los Servicios de Urología (87,9%). Hubo una gran heterogeneidad en las clásicas variables clínico-patológicas como criterios de selección. La densidad de antígeno prostático específico (PSAd) solo se usaba en el 36,4% IA. La RMmp era claramente infrautilizada como estadificación inicial (6%). Solo el 27,3% reconocía un alto nivel de experiencia en RMmp de sus colegas radiólogos. Con relación a la biopsia de confirmación, la mayoría de los centros utilizaban la vía transrectal y solo 2/33 la vía transperineal/software de fusión. La mitad de los IA entrevistados pasaron a tratamiento activo ante progresión patológica a Gleason 7 (3 + 4). No existió consenso en cuanto a cuándo pasar a estrategia de observación. Conclusiones: El estudio demostró la infrautilización del consentimiento informado y de los cuestionarios de calidad de vida. El PSAd no se incluía como elemento decisor en la estrategia inicial en la mayoría. Se plasmó una desconfianza en la experiencia de los urólogos con la RMmp y una infrautilización de la vía transperineal, así como la no existencia de consenso en los protocolos de seguimiento y en los criterios de tratamiento activo., confirmando la necesidad de estudios prospectivos analizando el papel de la RMmp y los biomarcadores. Background: Our main objective was to report the current use of active surveillance in Spain and to identify areas for potential improvement. Methods: A questionnaire generated by the Platform for Multicentre Studies of the Spanish Urology Association (AEU/PIEM/2014/0001, NCT02865330) was sent to all associate researchers from January to March 2016. The questionnaire included 7 domains covering various aspects of active surveillance. Results: Thirty-three of the 41 associate researchers responded to the questionnaire. Active surveillance is mainly controlled by the urology departments (87.9%). There was considerable heterogeneity in the classical clinical-pathological variables as selection criteria. Only 36.4% of the associate researchers used prostate-specific antigen density (PSAd). Multiparametric magnetic resonance imaging (mpMRI) was clearly underused as initial staging (6%). Only 27.3% of the researchers stated that their radiology colleagues had a high level of experience in mpMRI. In terms of the confirmation biopsy, most of the centres used the transrectal pathway, and only 2 out of 33 used the transperineal pathway or fusion software. Half of the researchers interviewed applied active treatment when faced with disease progression to Gleason 7 (3+4). There was no consensus on when to transition to an observation strategy. Conclusions: The study showed the underutilisation of informed consent and quality-of-life questionnaires. PSAd was not included as a decisive element in the initial strategy for most researchers. There was a lack of confidence in the urologists’ mpMRI experience and an underutilisation of the transperineal pathway. There was also no consensus on the follow-up protocols and active treatment criteria, confirming the need for prospective studies to analyse the role of mpMRI and biomarkers

4kscore test, prostate cancer prevention trial-risk calculator y european research screening prostate-risk calculator en la predicción del cáncer de próstata de alto grado; estudio preliminar

Introducción: Frente al sobrediagnóstico y al sobretratamiento en cáncer de próstata (CaP) se establecen estrategias terapéuticas como la vigilancia activa o la terapia focal, o métodos para precisar el diagnóstico del CaP de alto grado (CaP-AG), Gleason = 7, como la resonancia magnética multiparamétrica o nuevos marcadores como el 4Kscore Test (4KsT).: Es nuestro propósito testar mediante un estudio piloto la capacidad del 4KsT como identificador de CaP-AG (suma de Gleason = 7) en biopsia de próstata (Bx) y compararlo con otros modelos pronósticos multivariantes disponibles, como el Prostate Cancer Prevention Trial-Risk Calculator 2.0 (PCPTRC 2.0) y el European Research Screening Prostate Cancer-Risk Calculator 4 (ERSPC-RC 4). Material y métodos: Cincuenta y un pacientes sometidos a BxP según práctica clínica habitual, con un mínimo de 10 cilindros. Diagnóstico de CaP-AG consensuado por 4 uropatólogos. Comparación de las predicciones ofrecidas por los diferentes modelos mediante prueba U Mann-Whitney, áreas bajo la curva ROC (AUC) (test de DeLong), funciones de densidad de probabilidad, diagramas de caja y curvas de utilidad clínica (CUC). Resultados: Un 43% presentaron CaP y un 23,5% CaP-AG. Las medianas de probabilidad de 4KsT, PCPTRC 2.0 y ERSPC-RC 4 fueron significativamente diferentes entre los pacientes con CaP-AG y no CaP-AG (p = 0,022), siendo más diferenciadas en el caso de 4KsT (mediana en CaP-AG: 51,5% [percentil 25-75: 25-80,5%], frente a 16% [P 25-75: 8-26,5%] en no CaP-AG [p = 0,002]). Todos los modelos mostraron AUC por encima de 0,7 sin diferencias significativas entre ninguno de ellos y 4KsT (p = 0,20). Las funciones de densidad de probabilidad y diagramas de caja muestran una buena capacidad discriminativa, especialmente en los modelos de ERSPC-RC 4 y 4KsT. Las CUC muestran como un punto de corte del 9% de 4KsT identifica a todos los CaP-AG y permite un ahorro del 22% de biopsias, similar a lo que ocurre con los modelos de ERSPC-RC 4 y un punto de corte del 3%. Conclusiones: Los modelos predictivos evaluados ofrecen una buena capacidad de discriminación del CaP-AG en Bx. 4KsT es un buen modelo clasificatorio en su conjunto, seguido de ERSPC-RC 4 y PCPTRC 2.0. Las CUC permiten sugerir puntos de corte de decisión clínica: 9% para 4KsT y 3% en ERSPC-RC 4. Este estudio preliminar debe ser interpretado con cautela por su limitado tamaño muestral. Introduction: To prevent the overdiagnosis and overtreatment of prostate cancer (PC), therapeutic strategies have been established such as active surveillance and focal therapy, as well as methods for clarifying the diagnosis of high-grade prostate cancer (HGPC) (defined as a Gleason score =7), such as multiparametric magnetic resonance imaging and new markers such as the 4Kscore test (4. KsT).By means of a pilot study, we aim to test the ability of the 4. KsT to identify HGPC in prostate biopsies (Bx) and compare the test with other multivariate prognostic models such as the Prostate Cancer Prevention Trial Risk Calculator 2.0 (PCPTRC 2.0) and the European Research Screening Prostate Cancer Risk Calculator 4 (ERSPC-RC 4). Material and methods: Fifty-one patients underwent a prostate Bx according to standard clinical practice, with a minimum of 10 cores. The diagnosis of HGPC was agreed upon by 4 uropathologists. We compared the predictions from the various models by using the Mann-Whitney U test, area under the ROC curve (AUC) (DeLong test), probability density function (PDF), box plots and clinical utility curves. Results: Forty-three percent of the patients had PC, and 23.5% had HGPC. The medians of probability for the 4. KsT, PCPTRC 2.0 and ERSPC-RC 4 were significantly different between the patients with HGPC and those without HGPC (p=.022) and were more differentiated in the case of 4. KsT (51.5% for HGPC 25-75 percentile: 25-80.5%] vs. 16% P 25-75: 8-26.5%] for non-HGPC; p = 002). All models presented AUCs above 0.7, with no significant differences between any of them and 4. KsT (p=.20). The PDF and box plots showed good discriminative ability, especially in the ERSPC-RC 4 and 4. KsT models. The utility curves showed how a cutoff of 9% for 4. KsT identified all cases of HGPC and provided a 22% savings in biopsies, which is similar to what occurs with the ERSPC-RC 4 models and a cutoff of 3%. Conclusions: The assessed predictive models offer good discriminative ability for HGPCs in Bx. The 4. KsT is a good classification model as a whole, followed by ERSPC-RC 4 and PCPTRC 2.0. The clinical utility curves help suggest cutoff points for clinical decisions: 9% for 4. KsT and 3% for ERSPC-RC 4. This preliminary study should be interpreted with caution due to its limited sample size

Validación de un instrumento para la medida de los procesos de gestión del conocimiento en entornos masivos en línea [Validation of an instrument to assess the knowledge management processes in massive open online enviroment, a MOOC]

La gestión del conocimiento es un valor en alza en nuestra sociedad, en el mundo empresarial es sabido que una empresa tiene un valor “intangible” además del contable, que es función de su “saber-hacer”. Aunque se ha hecho mucha investigación sobre gestión del conocimiento en entornos empresariales, se han realizado pocos trabajos en el mundo de la educación y mucho menos en el entorno de los cursos masivos abiertos on-line (MOOC). En este trabajo presentamos la adaptación a los MOOC de un instrumento de medida de los procesos de gestión del conocimiento. La validación de este instrumento se ha realizado con un panel de expertos y con una prueba piloto valorada usando la técnica de Alfa de Cronbach, obteniéndose valores por encima de 0.7 para todos los ítems del instrumento. [Knowledge management is a rising topic in our society. In the business environment, a company has an accounting value and an immaterial value. The immaterial value depends on company know-how. Although a lot of research has done about knowledge management in business context, few works has done in educational context and still less work has done in massive open online courses (MOOC). In this communication, an adaptation of an assessment instrument in knowledge management processes in massive online courses context is advanced. The adaptation of the instrument was done with the support of an expert panel and a pilot test that was rated using the Alpha Cronbach technique. The instrument received a grade upper than 0.7 for each item of the instrument.
