Prediction and detection models for acute kidney injury in hospitalized older adults.

BMC medical informatics and decision making Mar 29, 2016
BACKGROUND: Acute Kidney Injury (AKI) occurs in at least 5 % of hospitalized patients and can result in 40-70 % morbidity and mortality. Even following recovery, many subjects may experience progressive deterioration of renal function. The heterogene...

RenalGuard system in high-risk patients for contrast-induced acute kidney injury.

American heart journal Dec 17, 2015
BACKGROUND: High urine flow rate (UFR) has been suggested as a target for effective prevention of contrast-induced acute kidney injury (CI-AKI). The RenalGuard therapy (saline infusion plus furosemide controlled by the RenalGuard system) facilitates ...
