    Abstract Background Isolated Left Ventricular Non-compaction (LVNC) is an uncommon disorder characterized by the presence of increased trabeculations and deep intertrabecular recesses. In adults, it has been found that Ejection Fraction (EF) decreases significantly as non-compaction severity increases. In children however, there are a few data describing the relation between anatomical characteristics of LVNC and ventricular function. We aimed to find correlations between morphological features and ventricular performance in children and young adolescents with LVNC using Cardiovascular Magnetic Resonance (CMR). Methods 15 children with LVNC (10 males, mean age 9.7 y.o., range 0.6 - 17 y.o.), underwent a CMR scan. Different morphological measures such as the Compacted Myocardial Mass (CMM), Non-Compaction (NC) to the Compaction (C) distance ratio, Compacted Myocardial Area (CMA) and Non-Compacted Myocardial Area (NCMA), distribution of NC, and the assessment of ventricular wall motion abnormalities were performed to investigate correlations with ventricular performance. EF was considered normal over 53%. Results The distribution of non-compaction in children was similar to published adult data with a predilection for apical, mid-inferior and mid-lateral segments. Five patients had systolic dysfunction with decreased EF. The number of affected segments was the strongest predictor of systolic dysfunction, all five patients had greater than 9 affected segments. Basal segments were less commonly affected but they were affected only in these five severe cases. Conclusion The segmental pattern of involvement of non-compaction in children is similar to that seen in adults. Systolic dysfunction in children is closely related to the number of affected segments.

    Medical education is undergoing significant transformations to better align with evolving healthcare needs. In 2015, the Pontificia Universidad Católica de Chile implemented a major curricular reform in its School of Medicine, shifting from a traditional 7-year program to an integrated, competency-based 6-year curriculum. This study aimed to assess the academic outcomes, clinical competencies, and differences in student well-being between both curricula. Methods:We conducted a prospective, longitudinal, comparative study of two cohorts: the last cohort under the traditional curriculum and the first cohort under the new curriculum. Three measurements were carried out along the study program: at the beginning, at the middle and at the last year of the program. Academic performance, professionalism, and clinical competencies were evaluated using standardized written tests, OSCEs and the National Medical Exam (EUNACOM). In addition, we compared the courses grades and attrition statistics along the studies. At these three points, students also answered a range of self-reporting instruments regarding distress, burnout, wellbeing, mindfulness, empathy and the educational environment. Results: Both cohorts achieved similar average grades and EUNACOM scores. The new curriculum cohort had a significantly lower course failure rate (7.6% vs 13%, p<0.01) and better outcomes in professionalism and communication. Final OSCE scores were slightly higher in Obstetrics/Gynecology and Family Medicine. Despite these improvements, both cohorts showed high and increasing levels of stress, burnout, and declining empathy, particularly in the final years. While the elevated levels of stress and anxiety observed among medical students are extensively documented in the literature, the COVID-19 pandemic may have exerted an additional influence on these outcomes. Conclusion: The new curriculum maintained academic performance while enhancing professionalism and reducing failure rates and training time. However, persistent mental health challenges underscore the need for stronger and more effective support systems. These findings reveal the value of competency-based education while highlighting the importance of holistic curricular evaluation.

    Resultados inmediatos y alejados del switch arterial en pacientes con dextrotransposición de grandes arterias: experiencia de 20 años
    (2013) Becker Rencoret, Pedro Antonio; Delgado, M.; Frangini Sanhueza, Patricia Andrea; González, R.; Urcelay Montecinos, Gonzalo; Clavería Rodríguez, Cristian; Garay Walls, Francisca; Zelada, Pamela; Springmüller P., Daniel; Lema F., Guillermo; Cerda, J.; Heusser Risopatron, Felipe
    Objetivos: Comunicar los resultados de la operación de switch arterial en pacientes portadores de dextro Transposición de Grandes Arterias (D-TGA) y evaluar su evolución en el tiempo. Pacientes y Método: Estudio retrospectivo de pacientes sometidos a switch arterial entre mayo de 1992 y noviembre de 2012. Se comparó período 1 (1992 a 2002) con período 2 (2003 a 2012). Se definió D-TGA simple aquella sin lesiones asociadas y D-TGA compleja aquella con asociación de comunicación interventricular o coartación aórtica. Resultados: Un total de 108 pacientes componen la serie, 44 en el período 1 y 64 en el período 2, sin diferencias demográficas y anatómicas entre ambos períodos. Setenta tenían D-TGA simple y 38 D-TGA compleja. La mortalidad operatoria en el período 1 fue 33% versus 8,4% en el período 2 (p< 0.025); hubo tendencia a mayor mortalidad en pacientes con anatomía coronaria compleja. Se observó una disminución del riesgo relativo de mortalidad de 68,7% en el período 2. El 28,7% presentaron complicaciones postoperatorias, sin diferencias entre ambos períodos. Un paciente falleció en forma alejada. La mediana de seguimiento fue de 60 meses y la supervivencia de 84,25% a 10 y 20 años. Se realizaron 16 re intervenciones, principalmente plastías percutáneas de ramas pulmonares. La mayoría de los pacientes se mantenían asintomáticos. La mortalidad operatoria de los últimos 5 años fue 2,6%. Conclusiones: La mortalidad operatoria ha disminuido significativamente a lo largo de 20 años; persiste un mayor riesgo en ciertos patrones de anatomía coronaria. La supervivencia alejada y libre de reintervenciones es muy favorable.
