Comparative effectiveness and safety of oral anticoagulants across kidney function in patients with atrial fibrillation.
Patients with atrial fibrillation and severely decreased kidney function were excluded from the pivotal non-vitamin K antagonist oral anticoagulants (NOAC) trials, thereby raising questions about comparative safety and effectiveness in patients with reduced kidney function. This study aimed to compare oral anticoagulants across the range of kidney function in patients with atrial fibrillation.

Comparative effectiveness of high-dose versus standard-dose influenza vaccine among patients receiving maintenance hemodialysis.
This study compared outcomes of routine dialysis patients who received either the standard dose vaccine (SDV) for influenza or a high-dose vaccine (HDV). Out of 22,215 influenza patient-seasons among adults 65 years and older, 97.4% received SDV and 2.6% received HDV. There did not seem to be any additional protection provided by the HDV for all-cause mortality or influenza-related outcomes.

Long-term outcomes of arteriovenous fistulas with unassisted versus assisted maturation: a retrospective national hemodialysis cohort study.
The authors retrospectively compared patients with assisted versus unassisted arteriovenous fistula (AVF) maturation for post-maturation AVF outcomes, including functional primary patency loss, AVF abandonment, and frequency of interventions. For the studied group of patients undergoing assisted AVF maturation, they observed a positive association between the number of pre-maturation AVF interventions and the likelihood of functional primary patency loss and frequency of post-maturation interventions.

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.

Comparative effectiveness of management strategies for renal artery stenosis: an updated systematic review.
This study compared benefits and harms of percutaneous transluminal renal angioplasty with stent placement (PTRAS) versus medical therapy alone in adults with atherosclerotic renal artery stenosis (ARAS). The strength of evidence regarding the relative benefits and harms of PTRAS versus medical therapy alone for patients with ARAS is low.

Management of renal masses and localized renal cancer: Systematic review and meta-analysis.
This review aimed to summarize evidence on effectiveness and comparative effectiveness of active surveillance (AS), thermal ablation (TA), and radical (RN) or partial nephrectomy (PN) for patients with a renal mass suspicious for localized renal cancer. It concluded that comparative studies demonstrated similar cancer-secific survival across management strategies, with some differences in renal functional outcomes, perioperative outcomes, and postoperative harms that should be considered when choosing a management strategy.

Comparative effect of contrast media type on the incidence of contrast-induced nephropathy: a systematic review and meta-analysis.
This review compared contrast-induced nephropathy (CIN) risk for contrast media within and between osmolality classes in patients receiving diagnostic or therapeutic imaging procedures. No differences were found in CIN risk among types of low-osmolar contrast media (LOCM). Iodixanol had a slightly lower risk for CIN than LOCM, but the lower risk did not exceed a criterion for clinical importance.

Effectiveness of prevention strategies for contrast-induced nephropathy: a systematic review and meta-analysis.
N-acetylcysteine, sodium bicarbonate, statins, and ascorbic acid have been studied for reducing contrast-induced nephropathy (CIN). This study evaluated the comparative effectiveness of interventions to reduce CIN in adults receiving contrast media. It concluded that the greatest reduction in CIN was seen with N-acetylcysteine plus IV saline in patients receiving LOCM and with statins plus N-acetylcysteine plus IV saline.

Comparative effectiveness of iron and erythropoiesis-stimulating agent dosing on health-related quality of life in patients receiving hemodialysis.
The researchers examined the independent associations of bolus versus maintenance iron dosing and high versus low erythropoiesis-stimulating agents (ESA) dosing on health-related quality of life (HRQoL). They found that for individuals with low baseline hemoglobin levels, higher ESA dosing and bolus iron dosing were associated with slightly higher HRQoL scores in follow-up.

Comparative short-term safety of sodium ferric gluconate versus iron sucrose in hemodialysis patients.
Despite different pharmacologic properties, little is known about the comparative safety of sodium ferric gluconate versus iron sucrose in hemodialysis patients. This study found that, overall, the 2 iron formulations studied exhibited similar safety profiles; however, ferric gluconate was associated with a slightly decreased risk for infection-related outcomes compared to iron sucrose among patients with a hemodialysis catheter.

Effect of intravenous iron use on hospitalizations in patients undergoing hemodialysis: a comparative effectiveness analysis from the DEcIDE-ESRD study.
The researchers studied the association of receipt of intravenous iron with hospitalizations in an incident cohort of hemodialysis patients. They concluded that a higher cumulative dose of intravenous iron may not be associated with increased risk of hospitalizations in hemodialysis patients. While clinical trials are needed, employing higher iron doses to reduce erythropoiesis-stimulating agents does not appear to increase morbidity in routine clinical care.

Validation study of medicare claims to identify older US adults with CKD using the Reasons for Geographic and Racial Differences in Stroke (REGARDS) Study.
The researchers compared characteristics and outcomes for individuals with chronic kidney disease (CKD) defined using laboratory measurements versus claims data from 6,982 study participants who had Medicare fee-for-service coverage. They found that CKD, whether identified using a claims-based algorithm or through estimated glomerular filtration rate or albumin-creatinine ratio measurements, is associated with increased risk for all-cause mortality and end-stage renal disease (ESRD).

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.
