CommentMeasuring risk in end-stage renal disease: is N-terminal pro brain natriuretic peptide a useful marker?
Natriuretic peptides are important in the maintenance of body volume homeostasis. There has been interest in utilizing the levels of these peptides to diagnose and prognosticate cardiovascular disease. In end-stage renal disease, the diagnostic utility of these peptides is limited. Madsen et al. report that levels of N-terminal pro brain natriuretic peptide (NT-proBNP) levels offer important information on the risk of mortality in patients undergoing hemodialysis.

CommentRenal albumin handling: a look at the dark side of the filter.
Renal albumin handling is of major interest because albuminuria is an important risk factor for reno-cardiovascular diseases. In this issue a challenging study attempts to shift the paradigm of very low fractional albumin filtration and degradation in proximal tubule cells. The conclusions are of great potential relevance but require urgent validation so that we gain a clearer view of the dark side of the glomerular filter.
