SummaryBackground and objectives The effect of in-hospital education on the adoption of home dialysis (peritoneal dialysis [PD] and home hemodialysis [HHD]) after an unplanned dialysis start is unknown.Design, setting, participants, & measurements Clinical demographics of consecutive patients acutely initiating hemodialysis (HD) from January 2005 to December 2009 were abstracted using institutional electronic records. All patients received multimedia chronic kidney disease education by the same advanced care nurse practitioner before discharge from the hospital. Clinical characteristics of patients choosing home dialysis or staying on in-center HD were compared. Results

The concentration or appearance rate of cancer antigen 125 (CA125) in peritoneal dialysis (PD) effluent has been used for many years as a biomarker for mesothelial cell mass in patients on PD. However, this marker has limitations, and emerging evidence has raised doubts as to its significance. This review explores our current understanding of CA125, its prominent role in studies of "biocompatible" PD solutions, and the ongoing uncertainty concerning its interpretation as a measure of mesothelial cell health.
