- ItemEnhancing Feedback Uptake and Self-Regulated Learning in Procedural Skills Training(2024) Villagrán Gutiérrez, Ignacio Andrés; Hernández Román, Rocío Belén; Schuit Condell, Gregory Kees; Neyem, Hugo Andrés; Fuentes Cimma, Javiera Carolina; Larrondo Vergara, María Loreto; Margozzini Delorenzo, Elisa; Hurtado Bunster, María Teresa; Iriarte Vásquez, Zoe; Miranda Mendoza, Constanza Sofía; Varas Cohen, Julián Emanuel; Hilliger Carrasco, IsabelRemote technology has been widely incorporated into health professions education. For procedural skills training, effective feedback and reflection processes are required. Consequently, supporting a self-regulated learning (SRL) approach with learning analytics dashboards (LADs) has proven beneficial in online environments. Despite the potential of LADs, understanding their design to enhance SRL and provide useful feedback remains a significant challenge. Focusing on LAD design, implementation, and evaluation, the study followed a mixed-methods two-phase design-based research approach. The study used a triangulation methodology of qualitative interviews and SRL and sensemaking questionnaires to comprehensively understand the LAD’s effectiveness and student SRL and feedback uptake strategies during remote procedural skills training. Initial findings revealed the value students placed on performance visualization and peer comparison despite some challenges in LAD design and usability. The study also identified the prominent adoption of SRL strategies such as help-seeking, elaboration, and strategic planning. Sensemaking results showed the value of personalized performance metrics and planning resources in the LAD and recommendations to improve reflection and feedback uptake. Subsequent findings suggested that SRL levels significantly predicted the levels of sensemaking. The students valued the LAD as a tool for supporting feedback uptake and strategic planning, demonstrating the potential for enhancing procedural skills learning.
- ItemEnteroparasitosis en la población de la tercera edad consultante en centros médicos de la Pontificia Universidad Católica de Chile, 1997(1998) Chen Shu Hsing; Codoceo Perez, Ana Carolina; Carrasco Salazar, Oriana Romanet; Torres Hidalgo, Marisa Lorena De Los LourLa población senil rara vez ha sido estudiada específicamente para determinar prevalencia de enteroparasitosis y sus repercusiones. Por lo anterior, se realizó un estudio retrospectivo a partir de 493 exámenes coproparasitológicos seriados analizados por técnica de PAF y Téleman y 9 Test de Graham realizados a pacientes senescentes en el laboratorio de parasitología de la Pontificia Universidad Católica de Chile, entre el 1° de Enero al 31 de Diciembre de 1997. Los resultados fueron analizados por sexo, edad, especies, y estación del año. Al analizar los resultados se encontró presencia de parásitos y/o comensales un 37,7% de los exámenes, de los cuales un 38,7% corresponde a parásitos, un 26,3% a comensales y un 34,9% ambos 20,3% presentó una sola especie, siendo el agente más frecuente el protozoo Blastocystis hominis 23,1%, seguido por los comensales Endolimax nana y Entamoeba coli con 14,1% y 12,7% respectivamente. Afecta en forma similar a ambos sexos y sin variación significativa estacional. A diferencia de los grupos pediátricos, Giardia lamblia no constituyó un agente frecuente en la tercera edad. Finalmente se considera necesario fomentar la realización de nuevos estudios que permitan conocer y mejorar aún más el manejo de la patología del paciente senescente, dada la mayor esperanza de vida que existe para éstos actualmente en las puertas del siglo XXI.
- ItemUpper-Limb Disability and the Severity of Lymphedema Reduce the Quality of Life of Patients with Breast Cancer-Related Lymphedema(2023) Ramirez Parada, Karol Lilia; González Santos, Angela ; Riady Aleuy, Layla ; Pinto, Mauricio P.; Ibáñez Cáceres, Carolina; Merino Lara, Tomás Rodrigo; Acevedo Claros, Francisco Nicolás; Walbaum García, Benjamín Vicente; Fernández Verdejo, Rodrigo ; Sánchez Rojel, César GiovanniBreast cancer-related lymphedema (BCRL) is characterized by arm swelling, pain, and discomfort, reducing the quality of life (QoL) of affected individuals. BRCL is caused via the blockage or disruption of the lymphatic vessels following cancer treatments, leading to an accumulation of fluid in the affected arm. While current BCRL rehabilitation treatments seek to reduce arm swelling, our study aimed to examine the impact of both the magnitude of lymphedema (ΔVolume) and arm disability on three dimensions of QoL: social, physical, and psychological. Using the Disabilities of the Arm, Shoulder, and Hand questionnaire (DASH) and the Upper Limb Lymphedema 27 questionnaire (ULL) in a group of 30 patients, we found that the magnitude of lymphedema (ΔVolume) was associated with the social dimension of QoL (r = 0.37, p = 0.041), but not with other dimensions. On the other hand, arm disability was associated with all evaluated dimensions of QoL (social, physical, and psychological: p < 0.001, p = 0.019, and p = 0.050 (borderline), respectively). These findings suggest that BCRL rehabilitation strategies should not only aim to reduce the magnitude of lymphedema but should also seek to improve or preserve arm functionality to enhance the QoL of BCRL patients.
