Análisis de la difusión y utilidad percibida a través de la implementación de una plataforma de formación virtual durante la pandemia por COVID-19 / Analysis of the broadcasting and perceived utility through the implementation of a virtual training platform during the pandemic

Introducción: La pandemia de COVID-19 ha afectado a las oportunidades de formación de los profesionales sanitarios, en parte porque se anularon muchos cursos presenciales. En este estudio se analizan los resultados de participación y satisfacción de las sesiones del Aula Virtual AEC durante su primer año. Métodos: El Aula Virtual AEC incluye un formato combinado de seminarios semanales emitidos en directo que pueden ser visionados en diferido. En este estudio se evalúan los resultados en sus primeros 12 meses, considerando el número de participantes en directo, el número de visualizaciones en diferido y el alcance global, así como los resultados de la encuesta de satisfacción realizada en cada una de las sesiones (1-10) Resultados: Desde el 16 de abril de 2020 hasta el 15 de abril de 2021 se realizaron 50 sesiones del Aula Virtual AEC. El alcance medio de las sesiones ha sido de 509 ± 288 visualizaciones con un rango entre 196 y 1490. En los picos de la pandemia se observó un descenso de los participantes en directo: 275 ± 135 vs. 391 ± 233 (p = 0,032) La puntuación media sobre el formato fue 8,46 ± 0,31/10. Las sesiones mejor puntuadas fueron las de temática relacionada con coloproctología con una diferencia estadísticamente significativa en la puntuación media 8,79 ± 0,42 vs. 8,39 ± 0,27 (p = 0,035). Un 90,76% de usuarios consideraron las sesiones útiles. Un 97,2% consideraban que deben mantenerse tras la pandemia. Conclusiones: El Aula Virtual AEC ha tenido muy buenos resultados en los primeros 12 meses de desarrollo, resultando ser una herramienta útil de docencia quirúrgica que previsiblemente sobrevivirá a la época de pandemia.

Introduction: The SARS-CoV-2 pandemic has affected training opportunities for healthcare professionals partly because face to face courses were cancelled. This study analyzes the results of participation and satisfaction of the AEC Virtual Classroom sessions during the first year. Methods: The AEC Virtual Classroom includes a combined format of weekly Webinar broadcast live that can be viewed on a delayed basis in a virtual platform. In this study, the results in its first year are evaluated considering the number of live participants, the delayed views and the global reach; as well as the results of the satisfaction survey in each of the sessions (0–10). Results: From 16/04/2020 to 15/04/2021, 50 sessions of the Virtual Classroom AEC were held. The average scope of the sessions was 509 ± 288 views with a range between 196 and 149. At the times of highest incidence of cases during the pandemic, a decrease in live participants was observed 275 ± 135 vs. 391 ± 233 (p = 0.032). The mean score on the format was 8.46 ± 0.31/10. The best-scored sessions were those of the subject related to coloproctology with a statistically significant difference in the mean score 8.79 ± 0.42 vs. 8.39 ± 0.27 (p = 0.035). 90% of users considered the sessions useful. 97.2% of respondents believe that the sessions should be maintained after the pandemic. Conclusions: The AEC Virtual Classroom has a very good results in the first year, proving to be a useful surgical teaching tool that will foreseeably survive once the pandemic is over. (AU)

Management of Leak after Single Anastomosis Duodeno-Ileal Bypass with Sleeve Gastrectomy.

The single anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI-S) has been introduced in the past few years for the treatment of morbid obesity. SADI-S has shown good results in terms of long-term results and short-term complications. However, the management of patients undergoing SADI-S and suffering from a leak is a great challenge for surgeons. We present an extensive review of the currently available literature on the management of leak after SADI in morbid obese (MO) patients. We aim at providing objective information regarding the optimal management, including diagnosis, technical options for the different strategies that have been proposed, to facilitate the selection of the best individual approach for each MO patient.

Pentoxifylline, tocopherol, and clodronate for the treatment of mandibular osteoradionecrosis: a systematic review.

OBJECTIVE: The purpose of this study was to evaluate the healing benefit provided by the antioxidant and antifibrotic properties of pentoxifylline-tocopherol or pentoxifylline-tocopherol-clodronate in combination therapy for osteoradionecrosis. STUDY DESIGN: We searched for relevant reports in PubMed by using a combination of "osteoradionecrosis" and the following keywords: "pentoxifillyne," "tocopherol," "vitamin E," or "clodronate." We considered articles in English or Spanish, with no limitations on the publication date. RESULTS: The combination of pentoxifylline plus tocopherol with or without clodronate was found to be effective for the treatment of mandibular osteoradionecrosis, although data were generally scarce and mostly came from retrospective case series. CONCLUSIONS: This drug therapy is well tolerated and could be promising for the treatment of mandibular osteoradionecrosis, but prospective randomized controlled clinical trials are needed for further clarification.

Efecto citoprotector del tacrolimus a dosis bajas sobre islotes de Langeerhans en cultivo sometidos a estímulos por citocinas del rechazo agudo / Cytoprotective effect of low-dose tacrolimus on islets of Langerhans in cultures subjected to stimulation by acute rejection cytokines

Introducción La mejoría de los resultados en el trasplante de islotes pancreáticos se debe en gran parte a la introducción de nuevos protocolos de inmunosupresión que incluyen, entre otros, tacrolimus a bajas dosis. Este fármaco tiene efectos antioxidantes y antiapoptóticos que podrían ser de utilidad en la prevención del rechazo primario. Objetivos Evaluar la respuesta in vitro a tacrolimus a bajas dosis en islotes de rata estimulados con citocinas proinflamatorias implicadas en el rechazo primario de islotes. Material y método Se cultivaron islotes de rata en medio RPMI determinándose producción de lipoperóxido (LPO) y óxido nítrico (NO) y marcadores de apoptosis (nucleosomas y Bcl-2) en presencia de IL-1 (50UI/ml) e IF-γ (1000UI/ml) y adición de tacrolimus (FK-506; 5ng/ml).Resultados Tras la estimulación se apreció un aumento muy significativo (p<0,01) de los marcadores de estrés oxidativo (LPO 10,1±1,16pmol/islote x 24; NO 19,1±3,28pmol/islote x 24h) y apoptosis (nucleosomas 0,24±0,04; Bcl-2 0,69±0,212). Dichos efectos fueron contrarrestados de manera significativa tras añadir tacrolimus, siendo la reversión completa (p NS frente a controles) en el caso de la producción de lipoperóxidos (1,58pmol/islote x 24h) y óxido nítrico (9,81pmol/islote x 24h) así como en el descenso de Bcl-2 (1,37±0,23Ui/islote).Conclusiones El efecto citoprotector in vitro del tacrolimus a bajas dosis sobre islotes estimulados con citocinas proinflamatorias consigue aminorar la generación de estrés oxidativo y la activación de la apoptosis, habitualmente implicados en el rechazo en las primeras 48h postimplante (AU)

Introduction The improvement in pancreatic islet transplantation results is due to immunosuppression protocols that include, among others, low-dose tacrolimus. Both anti-inflammatory and anti-oxidant effects of tacrolimus could be useful in preventing primary rejection. Aim To evaluate in vitro islet low-dose tacrolimus response after pro-inflammatory stimulation. Material and methodsIsolated rat islets were cultured in RPMI medium in the presence of IL-1 (50UI/mL) plus IF-γ (1000UI/mL) and tacrolimus (5ng/mL). The 24h production of lipoperoxide (LPO) and nitric oxide (NO) were measured as oxidative stress markers. Determination of apoptosis markers (nucleo some content and Bcl-2) was also performed. Results Oxidative stress (LPO 10.1±1.16pmol/islet x 24; NO 19.1±3.28pmol/islet x 24h) and apoptosis (nucleosome 0.24±0.04UI/islet; Bcl-2 0.69±0.212UI/islet) markers showed a very significant increase after cytokine stimulation (p<0.01). Both effects improved by adding tacrolimus to the medium. Protective effect was complete when lipoperoxide (1.58pmol/islet x 24h), nitric oxide (9.81pmol/islet x 24h) and Bcl-2 (1.37±0.23UI/islet) were determined. Conclusion In vitro cytoprotective effect of low-dose tacrolimus on isolated rat islets decreases both oxidative stress and apoptosis markers after stimulation of pro-inflammatory mediators (AU)

INTRODUCTION: The improvement in pancreatic islet transplantation results is due to immunosuppression protocols that include, among others, low-dose tacrolimus. Both anti-inflammatory and anti-oxidant effects of tacrolimus could be useful in preventing primary rejection. AIM: To evaluate in vitro islet low-dose tacrolimus response after pro-inflammatory stimulation. MATERIAL AND METHODS: Isolated rat islets were cultured in RPMI medium in the presence of IL-1 (50 UI/mL) plus IF-gamma (1000 UI/mL) and tacrolimus (5 ng/mL). The 24 h production of lipoperoxide (LPO) and nitric oxide (NO) were measured as oxidative stress markers. Determination of apoptosis markers (nucleosome content and Bcl-2) was also performed. RESULTS: Oxidative stress (LPO 10.1+/-1.16 pmol/islet x 24; NO 19.1+/-3.28 pmol/isletx24 h) and apoptosis (nucleosome 0.24+/-0.04 UI/islet; Bcl-2 0.69+/-0.212 UI/islet) markers showed a very significant increase after cytokine stimulation (p<0.01). Both effects improved by adding tacrolimus to the medium. Protective effect was complete when lipoperoxide (1.58 pmol/isletx24 h), nitric oxide (9.81 pmol/isletx24 h) and Bcl-2 (1.37+/-0.23 UI/islet) were determined. CONCLUSION: In vitro cytoprotective effect of low-dose tacrolimus on isolated rat islets decreases both oxidative stress and apoptosis markers after stimulation of pro-inflammatory mediators.

[Current status of islet transplantation]. / Estado actual del trasplante de islotes pancreáticos.

Due to the numerous advances in islet transplantation in the last few years, clinical outcomes following this procedure are continually improving. Novel immunosuppression protocols, improved donor and recipient selection, and careful attention to the process of organ extraction, preservation and islet isolation have contributed to long-term success. The present article reviews the results of clinical islet transplantation and their relationship with the different advances introduced. The use of new islet sources such as living and non-heart-beating donors, as well as recent advances in our knowledge of the mechanisms of rejection and its prevention, are also reviewed.

Estado actual del trasplante de islotes pancreáticos / Current status of islet transplantation

El trasplante de islotes pancreáticos mejora día a día sus resultados clínicos gracias a numerosas mejoras en el proceso desarrolladas en los últimos años. Tanto los nuevos protocolos de inmunosupresión como la selección de los donantes y receptores, así como un especial cuidado en la obtención, preservación y procesamiento de los páncreas, han hecho posible conseguir controles glucémicos prolongados. Uno de los objetivos principales de esta revisión es presentar la evolución de los resultados en humanos a medida que estos cambios han ido introduciéndose. Asimismo, se revisa el empleo de nuevas fuentes de islotes, como son el donante vivo y el donante a corazón parado, junto con los nuevos hallazgos en el conocimiento de los mecanismos de rechazo y las nuevas opciones terapéuticas desarrolladas para prevenirlo (AU)
