Energy Balance and Nutrition Status: A Prospective Assessment of Patients Undergoing Liver Transplantation.

Background: Energy balance (EB) and its relation to nutrition status throughout the perioperative period of liver transplantation (LTx) patients has been poorly reported in the literature, and this is the primary objective of the current study.

Methods: A prospective observational study was conducted with patients undergoing LTx, who were assessed before and after the operation. Resting energy expenditure, total energy expenditure (TEE), dietary intake, and EB were evaluated, as well as anthropometry, handgrip strength, and standard phase angle (SPA).
