Multicenter Study Comparative Study Observational StudyA Prospective International Multicenter Study of AKI in the Intensive Care Unit.
AKI is frequent and is associated with poor outcomes. There is limited information on the epidemiology of AKI worldwide. This study compared patients with AKI in emerging and developed countries to determine the association of clinical factors and processes of care with outcomes. ⋯ This study contrasts the clinical features and management of AKI and demonstrates worse outcomes in emerging than in developed countries. Differences in variations in care may explain these findings and should be considered in future trials.

Multicenter Study Observational StudyBiomarker Enhanced Risk Prediction for Adverse Outcomes in Critically Ill Patients Receiving RRT.
Higher plasma concentrations of inflammatory and apoptosis markers in critically ill patients receiving RRT are associated with RRT dependence and death. This study objective was to examine whether plasma inflammatory (IL-6, -8, -10, and -18; macrophage migration inhibitory factor) and apoptosis (death receptor-5, tumor necrosis factor receptor I and II) biomarkers augment risk prediction of renal recovery and mortality compared with clinical models. ⋯ This study suggests that a simple four-variable clinical model with plasma IL-8 had predictive value for renal recovery and mortality. These findings require external validation but could easily be used by clinicians.

Multicenter Study Comparative Study Observational StudyAn Incident Cohort Study Comparing Survival on Home Hemodialysis and Peritoneal Dialysis (Australia and New Zealand Dialysis and Transplantation Registry).
Home dialysis is often recognized as a first-choice therapy for patients initiating dialysis. However, studies comparing clinical outcomes between peritoneal dialysis and home hemodialysis have been very limited. ⋯ Home hemodialysis was associated with superior patient and technique survival compared with peritoneal dialysis.

Randomized Controlled Trial Multicenter Study Observational StudyAssociation of BP with Death, Cardiovascular Events, and Progression to Chronic Dialysis in Patients with Advanced Kidney Disease.
The optimal BP target to reduce adverse clinical outcomes in patients with CKD is unclear. This study examined the relationship between BP and death, cardiovascular events (CVEs), and kidney disease progression in patients with advanced kidney disease. ⋯ In patients with advanced kidney disease not undergoing dialysis, higher PP was strongly associated with CVE whereas higher SBP and DBP were associated with progression to long-term dialysis. These results suggest that SBP and DBP should not be the only factors considered in determining antihypertensive therapy; elevated PP should also be considered.

Randomized Controlled Trial Multicenter StudyObstructive Sleep Apnea Severity and Overnight Body Fluid Shift before and after Hemodialysis.
Obstructive sleep apnea is associated with significantly increased cardiovascular morbidity and mortality. Fluid overload may promote obstructive sleep apnea in patients with ESRD through an overnight fluid shift from the legs to the neck soft tissues. Body fluid shift and severity of obstructive sleep apnea before and after hemodialysis were compared in patients with ESRD. ⋯ Fluid overload influences overnight rostral fluid shift and obstructive sleep apnea severity in patients with ESRD undergoing intermittent hemodialysis. Although no benefit of hemodialysis on obstructive sleep apnea severity was observed in the whole group, the change in obstructive apnea-hypopnea index was significantly correlated with the change in fluid overload after hemodialysis. Moreover, the subgroup with lower fluid overload posthemodialysis showed a significantly lower obstructive sleep apnea severity, which provides a strong incentive to further study whether optimizing fluid status in patients with obstructive sleep apnea and ESRD will improve the obstructive apnea-hypopnea index.
