Lurz E, et al. - Experts sought to investigate whether children with end-stage liver disease (ESLD) could have smaller psoas muscle surface area (PMSA) than healthy controls. In children with ESLD, PMSA was significantly lower compared with healthy age- and gender-matched controls. In children with the advanced liver disease, PMSA could represent a novel objective nutritional biomarker as this finding was independent of growth in ESLD subjects.
