Efficacy of drug-coated balloon catheters for patients with short-term recurrent dysfunction of arteriovenous fistula.

Background: In this study, we aimed at clarifying the usefulness of drug-coated balloon catheters (DCBs) for arteriovenous fistulas (AVFs) that repeatedly undergo restenosis over a short period and to examine the factors that influence the patency period after DCB use.

Methods: This retrospective observational study was conducted using IN.PACT AV in 29 cases of AVFs with repeated restenosis within approximately 3 months, and temporary patency before and after DCB use in the same patients was compared.

Role of endothelial hyaluronan in peritoneal membrane transport and disease conditions during peritoneal dialysis.

Peritoneal membrane dysfunction in peritoneal dialysis (PD) is primarily attributed to angiogenesis; however, the integrity of vascular endothelial cells can affect peritoneal permeability. Hyaluronan, a component of the endothelial glycocalyx, is reportedly involved in preventing proteinuria in the normal glomerulus. One hypothesis suggests that development of encapsulating peritoneal sclerosis (EPS) is triggered by protein leakage due to vascular endothelial injury.

The impact of hemodialysis schedules on the day of the week of hospitalization for cardiovascular and infectious diseases, over a period of 20 years.

There have been no studies as yet that have evaluated how hemodialysis (HD) schedules affect the day of the week of hospitalization for cardiovascular diseases (CVDs) and infectious diseases (IDs), over a period of time. Herein, we performed a retrospective observational cohort study (1995-2014) evaluating 11,111 hospitalizations in 1,953 patients with end-stage renal disease, receiving HD 3 times a week (following either a Monday-Wednesday-Friday [MWF] schedule or a Tuesday-Thursday-Saturday [TTS] schedule) or receiving frequent HD (FHD) at least 4 times a week. Overall, hospitalization rates for CVDs and IDs were the highest on Monday in the MWF schedule and Tuesday in the TTS schedule compared to the average rates for all the days of the week.
