Meta AnalysisOff-pump coronary artery bypass surgery and acute kidney injury: a meta-analysis of randomized controlled trials.
Off-pump coronary artery bypass grafting (CABG) has been advocated to cause less inflammation, morbidity, and mortality than the more traditional on-pump technique. This meta-analysis compares these two surgical techniques with respect to causing acute kidney injury (AKI). ⋯ Off-pump CABG may be associated with a lower incidence of postoperative AKI but may not affect dialysis requirement, a serious complication of cardiac surgery. However, the different definitions of AKI used in individual trials and methodological concerns preclude definitive conclusions.

Multicenter Study Comparative StudyOutcome of acute kidney injury with different treatment options: long-term follow-up.
The multicenter Stuivenberg Hospital Acute Renal Failure 4 study investigated outcome in patients with acute kidney injury (AKI) stratified according to disease severity by the Stuivenberg Hospital Acute Renal Failure score. Patients in need of renal replacement therapy (RRT) received intermittent RRT or continuous RRT. This study investigated long-term mortality, renal function, comorbidity, and quality of life. ⋯ Long-term outcome of AKI consists of a high additional mortality unrelated to treatment modality offered during hospitalization, varying evolution of renal recovery, and many comorbidities, but a mental health at the same level as the general population.

Comparative StudyCystatin C as a marker of acute kidney injury in the emergency department.
The diagnosis of acute kidney injury (AKI) is usually based on changes in serum creatinine, which is a poor marker of early renal dysfunction. The discriminative and predictive abilities of serum and urinary cystatin C were examined for the prediction of AKI. ⋯ Serum cystatin C is an early, predictive biomarker of AKI, which outperforms serum creatinine in the heterogeneous emergency department setting. However, neither biomarker discriminated between AKI and CKD. Additional biomarkers continue to be needed for improved specificity in the diagnosis of community-acquired AKI.
