Antecedentes: se ha reportado una asociación entre el aumento del consumo de bebidas azucaradas y varias enfermedades metabólicas. Objetivo: evaluar el efecto del consumo de bebidas azucaradas sobre la obesidad en un periodo de 12 meses en mexicanos de 15 a 19 años. Métodos: el diseño del estudio fue prospectivo, con 12 meses de seguimiento. Se midieron el peso, la talla y la circunferencia de cintura (CC), y se calculó el puntaje z de índice de masa corporal (IMC). Se aplicó un cuestionario sobre consumo de 19 bebidas. ⋯ Al final del estudio, un 25% de los participantes consumían más de 50 g de azúcar proveniente de las bebidas. Quienes consumieron 50 g de azúcar o más al día presentaron mayor riesgo de aumentar la CC ≥ 2 cm (RR = 1,19, IC 95%, 1,03-1,39, p = 0,02). Quienes mantuvieron el consumo de bebidas azucaradas durante 12 meses, al compararlo con los que disminuyeron el consumo a 10 g/día, presentaron 71% más probabilidades de aumentar a un puntaje de IMC ≥ 2 (RR = 1,71, IC 95%, 1,03-2,86, p = 0,039). Conclusión: el alto consumo de bebidas azucaradas aumentó las probabilidades de aumentar de peso y de circunferencia de cintura.

The objective of this study was to isolate endophytic fungi producing paclitaxel from yew for the purpose of paclitaxel manufacture. Surface sterilized bark of Taxus wallichiana var. mairei was used as source material and potato dextrose agar culture medium was used in isolation of endophytic fungi. Fungal cultures were extracted with a mixture of chloroform / methanol (1:1, v/v) and the paclitaxel in the extracts was determined and authenticated with LC-MS. ⋯ The paclitaxel productivity in whole PDB culture and that in spent culture medium from this strain is 0.0153 mg/L and 0.0119 mg/L respectively. The paclitaxel content in dry mycelium is 0.27 mg/kg. This isolated endophytic fungus produced paclitaxel at a considerable level and shows potentiality as a producing strain for paclitaxel manufacture after strain improvement.

to determine the prevalence of malnutrition in patients aged 65 years or more at admission and factors associated with its presence. Analyze excess hospital stay (EHS), economic impact and premature readmission rate associated with hospital malnutrition in elderly patient. ⋯ hospital malnutrition in elderly patients remains an unsolved problem, given the high prevalence found, associated to an excess of hospital stay and increased hospital costs, especially in patients with moderate to severe malnutrition. The CONUT is a nutritional screening tool very useful for the speed and validity of their results, and allows detecting patients at risk or nutritional alert without lead to increased costs.
