Objetivo: caracterizar demográfica, clínica y quirúrgicamente, los casos de histerectomías, abdominales y vaginales, realizados en el Hospital Daniel Alcides Carrión entre enero a diciembre del 2010. Métodos: estudio de tipo observacional, descriptivo, transversal y retrospectivo realizado en el Hospital Nacional Daniel Alcides Carrión. Se incluyó a toda la población de pacientes sometidas a histerectomía entre enero a diciembre 2010. Se pesquisaron los reportes operatorios de Sala de Operaciones, luego, se revisaron las historias clínicas. La presente investigación fue aprobada por el comité metodológico y ético del hospital en cuestión. Resultados: en el tiempo de estudio, se realizaron en total 243 histerectomías. 172 casos (70,8%) fueron histerectomías abdominales y 71 casos (29,2%) fueron histerectomías vaginales. La edad promedio de las pacientes fue 51,5 ±11,1 ...

Secondary forests and coffee cultivation systems with shade trees might have great potential for carbon sequestration as a means of climate change adaptation and mitigation. This study aimed to measure carbon stocks in coffee plantations under different managements and secondary forest systems in the Peruvian Amazon rainforest (San Martín Region). The carbon stock in secondary forest trees was estimated using allometric equations, while carbon stocks in soil, herbaceous biomass, and leaf litter were determined through sampling and laboratory analysis. The biomass carbon stock in secondary forests was 132.2 t/ha, while in coffee plantations with Inga sp. shade trees it was 118.2 t/ha. Carbon stocks were 76.5 t/ha in coffee with polyculture farming, and the lowest amount of carbon was found in coffee without shade trees (31.1 t/ha). The carbon sequestered by coffee plants in all agrofores...
