Impact of quality improvement initiatives to improve CKD referral patterns: a systematic review protocol.

Introduction: Chronic kidney disease (CKD) is a global-health problem. A significant proportion of referrals to nephrologists for CKD management are early and guideline-discordant, which may lead to an excess number of referrals and increased wait-times. Various initiatives have been tested to increase the proportion of guideline-concordant referrals and decrease wait times.

Salvage of Malfunctioning Peritoneal Dialysis Catheters: An Algorithm for Recanalization and Repositioning.

A peritoneal dialysis catheter salvage algorithm was developed and performed for 40 patients with documented catheter malfunction (obstruction and/or malposition) referred to the interventional radiology suite. This procedure utilized a metallic stiffener for repositioning and rotating dual guide wires for recanalization. A retrospective analysis of 35 cases of fluoroscopic manipulation showed that in 83% of the cases, the catheters were successfully repositioned and/or recanalized, and in 59%, they remained patent at 30 days.

Effectiveness of a simple intervention for prevention of catheter-associated urinary tract infections on a medical hospital unit.

Background: Urinary tract infections (UTI) are one of the most common hospital-acquired infections with 80% as a result of urinary catheterisation.

Aim/objective: This study examined the impact of a simple intervention consisting of a daily chart reminder in patients with indwelling urinary catheters (IUC) on the duration of catheter use and the incidence of catheter-associated UTIs (CAUTIs).

Methods: The trial used a prospective pretest-post-test design with a control group over a six-month period conducted on two medical units of a community teaching hospital.

Electronic Advice Request System for Nephrology in Alberta: Pilot Results and Implementation.

Background: Residents of rural areas of Alberta face significant barriers regarding access to specialist care, resulting in delays in provision of optimal care. Electronic referral and consultation systems are promising tools for facilitating timely access to specialist care, especially for people living in rural locations.

Objective: To report our initial experience with the launch of an electronic advice request system for ambulatory kidney care in Alberta, Canada.

Buttonhole versus rope-ladder cannulation of arteriovenous fistulas for hemodialysis: a systematic review.

Background: The buttonhole technique is an alternative method of cannulating the arteriovenous fistula (AVF) in hemodialysis (HD), frequently used for home HD patients. However, the balance of risks and benefits of the buttonhole compared with the rope-ladder technique is uncertain.

Study Design: A systematic review of randomized trials and observational studies (case reports, case series, studies without a control group, non-English studies, and abstracts were excluded).

Intensive glycemic control in type 2 diabetics at high cardiovascular risk: do the benefits justify the risks?

Perkovic et al. use novel data from the ADVANCE study to report on the potential renal benefits of standard glycemic control, compared with intensive glycemic control (mean hemoglobin A1c 7.3 and 6.

Association between glycemic control and adverse outcomes in people with diabetes mellitus and chronic kidney disease: a population-based cohort study.

Background: Better glycemic control as reflected by lower hemoglobin A(1c) (HbA(1c)) level may prevent or slow progression of nephropathy in people with diabetes mellitus (DM). Whether a lower HbA(1c) level improves outcomes in people with DM and chronic kidney disease (CKD) is unknown.

Methods: From all people with serum creatinine measured as part of routine care in a single Canadian province from 2005 through 2006, we identified those with CKD based on laboratory data (estimated glomerular filtration rate [eGFR], <60.

Glycemic control and the risk of death in 1,484 patients receiving maintenance hemodialysis.

Background: It is controversial whether tighter glycemic control is associated with better clinical outcomes in people with kidney failure. We aim to determine whether worse glycemic control, measured using serum glucose and hemoglobin A(1c) (HbA(1c)) levels, is independently associated with higher mortality in patients undergoing maintenance hemodialysis.

Study Design: Retrospective cohort study.

Statins for treatment of dyslipidemia in chronic kidney disease.

Dyslipidemia is a potent cardiovascular (CV) risk factor in the general population. Elevated low-density lipoprotein cholesterol (LDL-C) and/or low high-density lipoprotein (HDL-C) are well-established CV risk factors, but more precise determinants of risk include increased apoprotein B (ApoB), lipoprotein(a) [Lp(a)], intermediate and very low-density lipoprotein (IDL-C, VLDL-C; "remnant particles"), and small dense LDL particles. Lipoprotein metabolism is altered in association with declining glomerular filtration rate such that patients with non dialysis-dependent chronic kidney disease (CKD) have lower levels of HDL-C, higher triglyceride, ApoB, remnant IDL-C, remnant VLDL-C, and Lp(a), and a greater proportion of oxidized LDL-C.

Combination therapy with an angiotensin receptor blocker and an ACE inhibitor in proteinuric renal disease: a systematic review of the efficacy and safety data.

Blockade of the renin-angiotensin system with either an angiotensin-converting enzyme (ACE) inhibitor or an angiotensin receptor blocker (ARB) was shown to decrease urinary protein excretion and slow the progression of both diabetic and nondiabetic proteinuric renal disease. The safety and efficacy of combined ACE-inhibitor and ARB therapy is not well established. We conducted a systematic review and meta-analysis of randomized trials evaluating the combination of an ACE inhibitor and an ARB in patients with chronic proteinuric renal disease.

Vascular access complications in daily dialysis: a systematic review of the literature.

Patients treated for end stage renal disease (ESRD) have a shorter life expectancy and a poorer quality of life than the general population. In an attempt to improve outcomes for this patient population, a few novel therapeutic approaches have been undertaken. With hemodialysis, an increase in dialysis frequency and/or time has been associated with improvements in anemia, left ventricular hypertrophy, hypertension, hyperphosphatemia, nutrition and quality of life.

Frequency-dependent regulation of cardiac Na(+)/Ca(2+) exchanger.

The activity of the cardiac Na(+)/Ca(2+) exchanger (NCX1.1) undergoes continuous modulation during the contraction-relaxation cycle because of the accompanying changes in the electrochemical gradients for Na(+) and Ca(2+). In addition, NCX1.

Inhibition of Na+/Ca2+ exchange by KB-R7943: transport mode selectivity and antiarrhythmic consequences.

The Na+/Ca2+ exchanger plays a prominent role in regulating intracellular Ca2+ levels in cardiac myocytes and can serve as both a Ca2+ influx and efflux pathway. A novel inhibitor, KB-R7943, has been reported to selectively inhibit the reverse mode (i.e.
