Medical education for undergraduate research: Proposals from the experience of two national student conferences of the Universidad de Valparaíso. / Educación médica para la investigación en pregrado: propuestas desde la experiencia de dos congresos estudiantiles nacionales de la Universidad de Valparaíso.

Introduction: Scientific research promotes the development of essential skills for medical practice. However, student participation in research projects is low, with multiple limitations and students' perceptions of deficient research skills. This study aims to describe the organization of the two medical student conferences held by the Scientific Society of Medical Students of the Universidad de Valparaíso and to analyze the papers presented. Finally, we make recommendations for promoting scientific research among medical students. Methods: An analytical cross-sectional study was conducted, including all the presentations given at the conferences. Results: The conferences comprised four phases: registration, evaluation, selection, and presentation. A total of 399 papers were received. A total of 157 case reports and 12 cross-sectional studies were presented, including 797 authors (56.7% women) from 21 universities. Most of the first authors were women in the internship cycle at public universities. The specialties with the highest representation were internal medicine (32.5%), pediatrics (18.3%) and surgery (13%). In the case reports, the best-evaluated section was the title (6.66 ± 0.76), and the worst-evaluated section was the discussion (6.17 ± 0.84). The case reports from private universities scored significantly higher in six of the eight items assessed. Conclusions: Greater participation was represented by students in their internship cycle presenting case reports. The worst evaluated section was the discussion, which could reflect difficulties in the research process. It is crucial to increase student participation from the first years of the career and encourage their involvement in research. More studies are needed to evaluate student participation and barriers to scientific research.

Introducción: La investigación científica fomenta el desarrollo de competencias esenciales para la práctica médica. Sin embargo, la participación estudiantil en proyectos de investigación es baja, con múltiples limitaciones y percepción de habilidades investigativas deficientes por parte de los estudiantes. Los objetivos de este estudio son describir la organización de las dos jornadas de estudiantes de medicina realizadas por la Sociedad Científica de Estudiantes de Medicina de la Universidad de Valparaíso y caracterizar los trabajos presentados. Finalmente, se realizan recomendaciones para la promoción de la investigación científica en estudiantes de medicina. Métodos: Se realizó un estudio transversal analítico que incluyó todos los trabajos presentados en las jornadas. Resultados: Las jornadas comprendieron cuatro fases: inscripción, evaluación, selección y presentación. Se recibieron 399 trabajos. Se presentaron 157 reportes de caso y 12 estudios transversales, incluyendo 797 autores (56,7% mujeres) de 21 universidades. Mayormente, los primeros autores fueron mujeres cursando el ciclo de internados en universidades estatales. Las especialidades con mayor representación fueron medicina interna (32,5%), pediatría (18,3%) y cirugía (13%). En los reportes de caso, la sección mejor evaluada fue el título (6,66 ± 0,76) y la peor evaluada la discusión (6,17 ± 0,84). Los reportes de caso provenientes de universidades privadas obtuvieron una calificación significativamente mayor en seis de los ocho ítems evaluados. Conclusiones: La mayor participación estuvo representada por estudiantes cursando el ciclo de internados que presentaron reportes de caso. La sección peor evaluada fue la discusión, lo que podría reflejar dificultades en el proceso de investigación. Es crucial aumentar la participación estudiantil desde los primeros años de la carrera y fomentar su involucramiento en investigación. Se requieren más estudios para evaluar la participación y las barreras estudiantiles en investigación científica.

Kresimir Krnjevic (1927-2021) and GABAergic inhibition: a lifetime dedication.

After over seven decades of neuroscience research, it is now well established that γ-aminobutyric acid (GABA) is the main inhibitory neurotransmitter in the brain. In this paper dedicated to Kresimir Krnjevic (1927-2021), a pioneer and leader in neuroscience, we briefly highlight the fundamental contributions he made in identifying GABA as an inhibitory neurotransmitter in the brain and our personal interactions with him. Of note, between 1972 and 1978 Dr. Krnjevic was a highly reputed Chief Editor of the Canadian Journal of Physiology and Pharmacology.

Establishing a national strategy for shared research resources in biomedical sciences.

Contemporary science has become increasingly multi-disciplinary and team-based, resulting in unprecedented growth in biomedical innovation and technology over the last several decades. Collaborative research efforts have enabled investigators to respond to the demands of an increasingly complex 21st century landscape, including pressing scientific challenges such as the COVID-19 pandemic. A major contributing factor to the success of team science is the mobilization of core facilities and shared research resources (SRRs), the scientific instrumentation and expertise that exist within research organizations that enable widespread access to advanced technologies for trainees, faculty, and staff. For over 40 years, SRRs have played a key role in accelerating biomedical research discoveries, yet a national strategy that addresses how to leverage these resources to enhance team science and achieve shared scientific goals is noticeably absent. We believe a national strategy for biomedical SRRs-led by the National Institutes of Health-is crucial to advance key national initiatives, enable long-term research efficiency, and provide a solid foundation for the next generation of scientists.

A US Rectal Cancer Consortium Study of Inferior Mesenteric Artery Versus Superior Rectal Artery Ligation: How High Do We Need to Go?

BACKGROUND: The optimal level of pedicle ligation during proctectomy for rectal cancer, either at the origin of the inferior mesenteric artery or the superior rectal artery, is still debated. OBJECTIVE: The objective was to determine whether superior rectal artery ligation portends equivalent technical or oncologic outcomes. DESIGN: This was a retrospective analysis of a rectal cancer database (2007-2017). SETTINGS: The study was conducted at 6 tertiary referral centers in the United States (Emory University, University of Michigan, University of Pittsburgh Medical Center, The Ohio State University Wexner Medical Center, Vanderbilt University Medical Center, and Washington University School of Medicine in St. Louis). PATIENTS: Patients with primary, nonmetastatic rectal cancer who underwent low anterior resection or abdominoperineal resection were included. MAIN OUTCOME MEASURES: Anastomotic leak, lymph node harvest, locoregional recurrence-free survival, recurrence-free survival, and overall survival were measured. RESULTS: Of 877 patients, 86% (n = 755) received an inferior mesenteric artery ligation, whereas 14% (n = 122) received a superior rectal artery ligation. A total of 12%, 33%, 24%, and 31% were pathologic stage 0, I, II, and III. Median follow-up was 31 months. Superior rectal artery ligation was associated with a similar anastomotic leak rate compared with inferior mesenteric artery ligation (9% vs 8%; p = 1.0). The median number of lymph nodes removed was identical (15 vs 15; p = 0.38). On multivariable analysis accounting for relevant clinicopathologic factors, superior rectal artery ligation was not associated with increased anastomotic leak rate, worse lymph node harvest, or worse locoregional recurrence-free survival, recurrence-free survival, or overall survival (all p values >0.1). LIMITATIONS: This was a retrospective design. CONCLUSIONS: Compared with inferior mesenteric artery ligation, superior rectal artery ligation is not associated with either worse technical or oncologic outcomes. Given the potential risks of inadequate blood flow to the proximal limb of the anastomosis and autonomic nerve injury, we advocate for increased use of superior rectal artery ligation.

ESTUDIO DEL CONSORCIO DE CNCER DE RECTO DE ESTADOS UNIDOS DE LIGADURA BAJA DE LA ARTERIA MESENTRICA INFERIOR CONTRA LIGADURA ALTA DE LA ARTERIA MESENTRICA INFERIOR QU TAN ALTO DEBEMOS EXTENDERNOS: ANTECEDENTES:el nivel óptimo de la ligadura del pedículo en la proctectomía para el cáncer de recto, ya sea en el origen de la arteria mesentérica inferior o en la arteria rectal superior aún no esta definido.OBJETIVO:El objetivo era determinar si la ligadura de la arteria rectal superior pronostica resultados técnicos u oncológicos similares.DISEÑO:Análisis retrospectivo de una base de datos de cáncer de recto (2007-2017).ESCENARIO:el estudio se realizó en seis centros de referencia de tercer nivel en los Estados Unidos (Universidad de Emory, Universidad de Michigan, Centro médico de la Universidad de Pittsburgh, Centro médico Wexner de la Universidad Estatal de Ohio, Centro médico de la Universidad de Vanderbilt y Escuela de Medicina de la Universidad de Washington en St. Louis).PACIENTES:Se incluyeron pacientes con cáncer de recto primario no metastásico que se sometieron a resección anterior baja o resección abdominoperineal.PRINCIPALES VARIABLES ANALIZADAS:Se midió la fuga anastomótica, los ganglios linfáticos recuperados, la sobrevida sin recidiva locorregional, la sobrevida sin recidiva y la sobrevida global.RESULTADOS:De 877 pacientes, en el 86% (n = 755) se realizó una ligadura de la arteria mesentérica inferior, y en el 14% (n = 122) se realizó una ligadura de la arteria rectal superior. El 12%, 33%, 24% y 31% estaban en estadio patológico 0, I, II y III respectivamente. La mediana de seguimiento fue de 31 meses. La ligadura de la arteria rectal superior se asoció con una tasa de fuga anastomótica similar a la ligadura de la arteria mesentérica inferior (9 vs 8%, p = 1,0). La mediana del número de ganglios linfáticos extirpados fue idéntica (15 contra 15, p = 0,38). En el análisis multivariado que tiene en cuenta los factores clínico-patológicos relevantes, la ligadura de la arteria rectal superior no se asoció con una mayor tasa de fuga anastomótica, una peor cosecha de ganglios linfáticos o una peor sobrevida libre de recurrencia locorregional, sobrevida libre de recurrencia o sobrevida global (todos p> 0,1).LIMITACIONES:Diseño retrospectivo.CONCLUSIONES:En comparación con la ligadura de la arteria mesentérica inferior, la ligadura de la arteria rectal superior no se asocia a peores resultados técnicos ni oncológicos. Debido a los riesgos potenciales de un flujo sanguíneo inadecuado del muñon proximal de la anastomosis y la lesión de los nervios autonómicos, proponemos una mayor realización de la ligadura de la arteria rectal superior.
