Biomarker Proenkephalin Investigated in Diagnosis of Acute Kidney Injury

Liver transplantation (LT) is the only treatment available for patients with end-stage liver disease, such as liver cancer or acute and subacute liver failure. Among the various types of postoperative organ damage, acute kidney injury (AKI) is particularly prevalent, developing in 5% to 20% of patients undergoing major non-cardiac surgery. More...
