Objetivo: Determinar el efecto antibacteriano in vitro de Solanum tuberosum “papa” fermentado (tocosh) frente a una cepa de Helicobacter pylori ATCC 43504 y comparar con el efecto antibacteriano in vitro de Amoxicilina, Metronidazol y Claritromicina. Metodología: Se realizó un estudio preexperimental, in vitro, prospectivo y analítico, se seleccionó una muestra conformada por 28 repeticiones, 14 para el grupo experimental y 14 para grupo control, realizadas en las placas Petri con la cepa de Helicobacter pylori ATCC 43504. Se preparó una solución hidroalcohólica a 60° mediante la combinación de alcohol etílico al 96% y agua destilada. Se evaluó la inhibición del crecimiento antibacteriano in vitro mediante el método de Microdilución en caldo con lectura por resazurina previamente cultivado en Caldo BHI suplementado con suero fetal bovino (10%) e isovitalex (1%). Resulta...

Background. In Latin America, the prevalence of end-stage kidney disease (ESKD) has risen tremendously during the last decade. Previous studies have suggested that receiving dialysis at high altitude confers mortality benefits; however, this effect has not been demonstrated at >2000 m above sea level (masl) or in developing countries. Methods. This historical cohort study analyzed medical records from six Peruvian hemodialysis (HD) centers located at altitudes ranging from 44 to 3827 masl. Adult ESKD patients who started maintenance HD between 2000 and 2010 were included. Patients were classified into two strata based on the elevation above sea level of their city of residence: low altitude (<2000 masl) and high altitude (2000 masl). Death from any cause was collected from national registries and Cox proportional hazards models were built. Results. A total of 720 patients were enrolled a...
