Early acute kidney injury (AKI) diagnosis is needed to pursue treatment trials. We evaluated cystatin C (CysC) as an early biomarker of serum creatinine (SCr)-AKI and an alternative to define AKI. ⋯ Our findings do not support replacing SCr by CysC to define AKI. Early ICU CysC predicts SCr-AKI development and combined SCr-CysC-AKI definition leads to stronger AKI biomarker associations.

Maintaining hemoglobin (Hgb) levels within a target range is difficult. Non-invasive hematocrit monitoring (NIVH) continuously monitors both the hematocrit and percent change in intravascular blood volume in real time. Based on the data reported here, NIVH can be utilized as a tool for anemia management in pediatric hemodialysis patients. ⋯ The newly derived pediatric equation (pHgb = 0.28*CRIT Hct + 2.5) improved the prediction capability compared to the standard equation with lower false-negative and false-positive rates.
