Editor's choice - comparison of outcomes after open surgical and endovascular lower extremity revascularisation among end stage renal disease patients on dialysis.
This study compared outcomes of different revascularization surgeries among end stage renal disease (ESRD) patients with peripheral arterial disease (PAD). There is a high risk of complications for this surgery. Outcomes of endovascular revascularization (ER) and open surgical revascularisation (OSR) were compared. Outcomes measured included mortality and major amputation. There is a lower mortality risk for ER versus OSR. OSR has better 30-day limb salvage although there are similar long-term outcomes.

Gender disparities in vascular access surgical outcomes in elderly hemodialysis patients.
In this study, the investigators assessed clinically relevant arteriovenous fistulas (AVF) and arteriovenous grafts (AVG) surgical outcomes in elderly male and female patients initiating hemodialysis with a central venous catheter (CVC). The investigators concluded that while AVFs should be considered the preferred vascular access in most circumstances, clinical AVF surgical outcomes were uniformly worse in females. They suggest that clinicians should also consider AVGs as a viable alternative in elderly female patients initiating hemodialysis with a CVC to avoid extended CVC dependence.

Vascular access type, inflammatory markers, and mortality in incident hemodialysis patients: the Choices for Healthy Outcomes in Caring for End-Stage Renal Disease (CHOICE) study.
The researchers investigated the association between access type and inflammatory marker levels in 583 dialysis patients. They found that central venous catheters, compared with arteriovenous fistulas, are associated with a greater state of inflammation and the association of catheter use and mortality may be mediated by access-induced inflammation.

Leveraging practice-based research networks to accelerate implementation and diffusion of chronic kidney disease guidelines in primary care practices: a prospective cohort study.
This study was conducted to determine whether practice-based research networks (PBRNs) could increase dissemination, implementation, and diffusion of evidence-based treatment guidelines for chronic kidney disease by leveraging early adopter practices. After the intervention, the initial four PBRNs increased the use of ACEIs/ARBs, discontinuation of NSAIDs, testing for anemia, and testing and/or treatment for vitamin D deficiency. Most were able to recruit two additional practices, which also increased their use of ACEIs/ARBs and testing and/or treatment of vitamin D deficiency. The researchers concluded that, with some assistance, early adopter practices can facilitate the diffusion of evidence-based approaches to other practices.

An instrumental variable approach finds no associated harm or benefit with early dialysis initiation in the United States.
The estimated glomerular filtration rate (eGFR) at dialysis initiation has been rising. This study described geographic variation in estimated glomerular filtration rate (eGFR) at dialysis initiation and determine its association with mortality. It found no associated harm or benefit with early dialysis initiation in the United States.

Dialysis chains and placement on the waiting list for a cadaveric kidney transplant.
The purpose of this paper is to investigate the effect of dialysis facility chain status on renal transplantation therapy. The researchers concluded that dialysis chain affiliation expands previously observed ownership-related differences in placement on the waiting list, and for-profit ownership of dialysis chain facilities appears to be a significant impediment to access to renal transplants.

Objective sleep, a novel risk factor for alterations in kidney function: the CARDIA study.
The investigators determined the association between objectively measured sleep and 10-year changes in estimated glomerular filtration rate. They found that, in this community-based sample, shorter sleep and poorer sleep quality were related to higher kidney filtration rates over 10 years.

The effect of the Statewide Sharing variance on geographic disparity in kidney transplantation in the United States.
This study examined the effect of Statewide Sharing on geographic allocation disparity over time between donor service areas (DSAs) within Tennessee and Florida and compared them with geographic disparity between the DSAs within a state for all states with more than one DSA (California, New York, North Carolina, Ohio, Pennsylvania, Texas, and Wisconsin). Findings suggested that changes which are untested run the risk of unintended consequences, and Statewide Sharing should be further studied and considered.

Biomarkers of vascular calcification and mortality in patients with ESRD.
This study evaluated the association between selected calcification biomarkers and long-term mortality in a large prospective cohort of dialysis patients. It found that factors such as osteoprotegerin and fetuin-A may be risk factors for all-cause and cardiovascular mortality in patients undergoing dialysis, but they do not improve risk prediction.

Meta-analysis of the effect of automated contrast injection devices versus manual injection and contrast volume on risk of contrast-induced nephropathy.
The researchers conducted a meta-analysis examining the currently published evidence on the reduction of contrast volume and the possible reduction of contrast-induced nephropathy (CIN) with the use of automated contrast injectors (ACIs) versus manual injection. They found that the incidence of contrast-induced nephropathy was significantly reduced by 15% for those using ACIs compared with manual injection.
