Are serum retinyl esters associated with biochemical markers of liver dysfunction in adult participants in the third National Health and Nutrition Examination Survey ( NHANES III ) , 1988 -- 1994?
The prevalence of serum retinyl ester concentrations >10% of the total vitamin A concentration in the NHANES III sample was substantially higher than expected but elevated retinyl ester concentrations were not associated with abnormal liver function.
EUS is safe and accurate for tumor and node staging in esophageal cancer. The combination of CT plus EUS appears to be accurate for locoregional staging in esophageal cancer.
