Bacterias aisladas del jugo de fique con actividad antagónica sobre phytophthora infestans (mont.) de bary

Phytophthora infestans (Mont.) de Bary, causa pérdidas considerables en todas las áreas donde se cultivan Solanáceas. Su manejo se realiza por métodos químicos, biológicos y tradicionalmente por los agricultores utilizando jugo de fique. Se aislaron bacterias presentes en el jugo de fique y se evaluó el antagonismo contra P. infestans empleando el principio de la técnica de Bauer–Kirbyel. Se seleccionó el aislado con mayor inhibición para realizar una fermentación en jugo de fique estéril y pruebas de antagonismo contra P. infestans en cajas de agar tomate enmendadas con caldo fermentado. Finalmente, se realizó la caracterización molecular del aislado seleccionado mediante la secuencia parcial del gen ribsomal 16S rRNA. Se obtuvo 41 aislados, de los cuales ocho presentaron inhibición del crecimiento In Vitro de P. infestans. Se seleccionó el aislado M46 para las pruebas de antagonismo en placas de agar tomate enmendadas con 200 µL de caldo fermentado y se alcanzó un porcentaje de inhibición del 95,4% del crecimiento de P. infestans. El aislado M46 se identificó como Bacillus sp con un porcentaje de identidad del 85% con B. cereus. La cepa de Bacillus sp M46 tiene potencial como agente de control para el patógeno P. infestans

Responsabilidad social empresarial centrada en el bienestar de los colaboradores. Marco de realidad actual

Los desafíos contemporáneos para las organizaciones en el contexto de culturas, política y economías mundializadas han provocado un mayor interés por la puesta en escena de actividades dirigidas a potenciar la competitividad de las empresas. En este sentido, a mediados del siglo XX se empezó a gestar la Responsabilidad Social Empresarial, como una vía para garantizar el desarrollo de las empresas privadas, sin dejar de lado las acciones responsables en defensa de los diferentes actores involucrados (stakeholders) en los diferentes procesos empresariales. De acuerdo con lo anterior, se ha planteado una revisión documental teórica y empírica en donde se pueda visibilizar las tendencias investigativas y los posibles vacíos de conocimiento en los cuales el investigador posee oportunidad de gestar nuevos conocimientos. Para el desarrollo del presente artículo se tomó como base documentos teóricos para la implementación de la Responsabilidad Social Empresarial en las organizaciones además de artículos empíricos. Los primeros, provienen principalmente de instructivos, manuales, normas y libros que exponen ampliamente los fundamentos. Mientras los documentos empíricos, muestran los resultados de investigaciones ejecutadas en casos concretos en donde se identificó un problema a resolver, y se deseó describir una realidad concreta relacionada con la Responsabilidad Social Empresarial y el bienestar de los colaboradores. Para llevar a cabo esta indagación se utilizó una búsqueda sistemática dentro de repositorios de artículos investigativos y fuentes de publicaciones especializadas en Responsabilidad Social Empresarial

Las organizaciones desde una mirada del desarollo sostenible

En el presente libro se articulan en dos líneas, a saber, las organizaciones desde la región y las organizaciones desde el emprendimiento y la gestión. En la primera se analizan diferentes temáticas que dejan ver el uso adecuado de la ciencia y la tecnología, reconociendo el rol de los sectores tanto público como privado y de la sociedad civil en el desarrollo, productividad y competitividad de las organizaciones, por lo que se tienen temáticas como normas internacionales, emprendimiento, tasa representativa del mercado, direccionamiento estratégico en el sector de obras civiles, precios internos y externos del tipo de cambio, que permitan comprender la dinámica contemporánea de las organizaciones, a partir de las experiencias de los diferentes actores que participan en escenarios inclusivos, con el propósito de evidenciar los elementos de competitividad y perdurabilidad que contribuyen a la internacionalización organizacional.La segunda línea trata de las organizaciones en la región, donde se muestran resultados de investigaciones, como las tendencias mundiales en el sector funerario, estrategias de innovación empresarial y responsabilidad social empresarial para Mipymes. Usos agroindustriales de la hoja de coca, factores de competitividad en la ganadería, en el sector metalmecánico, redes socio institucionales en el sector lácteo, imagen comercial de empresario, estrategia de encadenamiento, patios productivos, aplicación del modelo desing thinking, gestión del conocimiento en Mipymes industriales, ecosistema de emprendimiento, microempresas sostenibles, territorios de paz que dejan ver las nuevas tendencias y temáticas de creatividad e innovación para fortalecer la pedagogía, las competencias, las redes de emprendimiento a través de las herramientas, modelos y estructuras de los esquemas emprendedores, que permitan la continua evolución de los mercados emergentes y sus diferentes actores

Colombian surgical outcomes study insights on perioperative mortality rate, a main indicator of the lancet commission on global surgery – a prospective cohort studyResearch in context

Summary: Background: Surgical care holds significant importance in healthcare, especially in low and middle-income countries, as at least 50% of the 4.2 million deaths within the initial 30 days following surgery take place in these countries. The Lancet Commission on Global Surgery proposed six indicators to enhance surgical care. In Colombia, studies have been made using secondary data. However, strategies to reduce perioperative mortality have not been implemented. This study aims to describe the fourth indicator, perioperative mortality rate (POMR), with primary data in Colombia. Methods: A multicentre prospective cohort study was conducted across 54 centres (hospitals) in Colombia. Each centre selected a 7-day recruitment period between 05/2022 and 01/2023. Inclusion criteria involved patients over 18 years of age undergoing surgical procedures in operating rooms. Data quality was ensured through a verification guideline and statistical analysis using mixed-effects multilevel modelling with a case mix analysis of mortality by procedure-related, patient-related, and hospital-related conditions. Findings: 3807 patients were included with a median age of 48 (IQR 32–64), 80.3% were classified as ASA I or II, and 27% of the procedures had a low-surgical complexity. Leading procedures were Orthopedics (19.2%) and Gynaecology/Obstetrics (17.7%). According to the Clavien–Dindo scale, postoperative complications were distributed in major complications (11.7%, 10.68–12.76) and any complication (31.6%, 30.09–33.07). POMR stood at 1.9% (1.48–2.37), with elective and emergency surgery mortalities at 0.7% (0.40–1.23) and 3% (2.3–3.89) respectively. Interpretation: The POMR was higher than the ratio reported in previous national studies, even when patients had a low–risk profile and low-complexity procedures. The present research represents significant public health progress with valuable insights for national decision-makers to improve the quality of surgical care.
