Infancia, dictadura y resistencia: hijos e hijas de la izquierda chilena (1973-1989)

(Descriptivo) En este artículo de investigación recuperamos la voz de los hijos-niños e hijas-niñas de la gente militante de la izquierda de Chile, a partir del análisis de sus producciones simbólicas y registros de la vida cotidiana tales como cartas, dibujos, objetos realizados entre 1973 y 1989, y entrevistas registradas en documentales de la época que se encuentran actualmente en el Museo de la Memoria y los Derechos Humanos de Santiago de Chile, analizadas desde la perspectiva de los nuevos estudios de la infancia. Reflexionamos respecto al modo en que los niños y niñas elaboran su juicio y sentido de la realidad y construyen un sentido ético que dialoga con la herencia intergeneracional, pero la excede, reflejando su activa participación en la construcción de una comunidad afectiva que trasciende los vínculos consanguíneos

RESUMEN Este estudio describe el efecto del aceite de canola sobre las proporciones de colesterol y vitamina E (α and γ tocopherol) en piernas y pechugas de pollos broiler. Ciento veinte pollos broiler de 1 d de edad fueron aleatoriamente asignados dentro de cuatro grupos de 32 pollos cada uno. Cada grupo fue dividido en cuatro subgrupos de ocho pollitos, los que recibieron una de las cuatro dietas conteniendo: 15% de aceite con diferentes porcentajes de aceite de canola (dieta 1: 0%; 2: 5%; 3: 10%; y 4: 15%) por 31 días. Los animales fueron sacrificados al día 45 para la obtención de muestras. Colesterol en piernas y γ tocoferol en piernas y también en pechugas no mostraron una tendencia clara acorde incrementaba el contenido de aceite de canola y decrecía el de aceite de maíz en las dietas (a pesar de las mayores proporciones de γ tocoferol encontradas en el aceite de maíz). En conclusión las proporciones de vitamin E encontradas en el aceite de canola no influenciaron las proporciones de vitamina E en el tejido muscular en pollos broiler. Palabras clave: antioxidantes: α tocoferol, γ tocoferol, carne de pollo. SUMMARY This article describes the effect of canola oil on cholesterol and vitamin E (α and γ tocopherol) proportion in broiler chicken legs and breast. One hundred and twenty eight 1-day old broiler chickens w e r e randomly assigned into 4 groups of 32 chicks each. Each group was divided into 4 subgroups of 8 chicks which received one of the four d i e t s c o n t a i n i n g 15% oil with different percentages of canola oil (diet 1: 0%; 2: 5%; 3: 10%; and 4: 15%) for 31 days. Animals were sacrificed at day 45 to obtain samples. Cholesterol in legs and γ tocopherol in legs and also chicken breast did not show a clear trend according increased canola and decreased corn oil in the diets (despite of the higher γ tocopherol proportions found in corn oil). In conclusion vitamin E proportions found in canola oil did not influence vitamin E proportions in muscle tissue in broiler chickens

Delayed colorectal cancer care during covid-19 pandemic (decor-19). Global perspective from an international survey

Background The widespread nature of coronavirus disease 2019 (COVID-19) has been unprecedented. We sought to analyze its global impact with a survey on colorectal cancer (CRC) care during the pandemic. Methods The impact of COVID-19 on preoperative assessment, elective surgery, and postoperative management of CRC patients was explored by a 35-item survey, which was distributed worldwide to members of surgical societies with an interest in CRC care. Respondents were divided into two comparator groups: 1) ‘delay’ group: CRC care affected by the pandemic; 2) ‘no delay’ group: unaltered CRC practice. Results A total of 1,051 respondents from 84 countries completed the survey. No substantial differences in demographics were found between the ‘delay’ (745, 70.9%) and ‘no delay’ (306, 29.1%) groups. Suspension of multidisciplinary team meetings, staff members quarantined or relocated to COVID-19 units, units fully dedicated to COVID-19 care, personal protective equipment not readily available were factors significantly associated to delays in endoscopy, radiology, surgery, histopathology and prolonged chemoradiation therapy-to-surgery intervals. In the ‘delay’ group, 48.9% of respondents reported a change in the initial surgical plan and 26.3% reported a shift from elective to urgent operations. Recovery of CRC care was associated with the status of the outbreak. Practicing in COVID-free units, no change in operative slots and staff members not relocated to COVID-19 units were statistically associated with unaltered CRC care in the ‘no delay’ group, while the geographical distribution was not. Conclusions Global changes in diagnostic and therapeutic CRC practices were evident. Changes were associated with differences in health-care delivery systems, hospital’s preparedness, resources availability, and local COVID-19 prevalence rather than geographical factors. Strategic planning is required to optimize CRC care
