Do low serum micronutrient concentrations predict frailty among older women living in the community?
Low serum micronutrient concentrations are an independent risk factor for frailty among disabled older women, and the risk of frailty increases with the number of micronutrient deficiencies.
Fentanyl is commonly used in surgical procedures in which there is a substantial risk of focal cerebral ischemia. Fentanyl did not affect cerebral injury produced by focal ischemia in the rat. The data suggest that, in doses that produce respiratory depression and muscle rigidity, fentanyl does not reduce the tolerance of the brain to a focal ischemic insult.
