Over 40% of US and Canadian adults have low basic literacy levels, suggesting that eHealth resources are likely to be inaccessible to large segments of the population. Using(More)
OBJECTIVE This study's objective was to assess knowledge of phosphorus compared with other nutrients in patients undergoing maintenance dialysis (MD). DESIGN We compared knowledge of phosphorus vs. other nutrients important to the MD diet (potassium, sodium, and protein) in patients undergoing hemodialysis (HD) and peritoneal dialysis (PD). We further(More)
BACKGROUND Chronic kidney disease (CKD) affects up to 19.2 million Americans, and untreated kidney disease can progress to kidney failure. Patient education is an important part of slowing disease progression, but the ability of health professionals to provide this education is limited by time constraints. To date, there have been no systematic evaluations(More)
BACKGROUND Hypomagnesaemia is a common side effect of cyclosporin A (CsA) therapy. Animal studies suggest that magnesium (Mg) supplementation inhibits chronic CsA nephropathy. METHODS To determine if low Mg levels correlate with true CsA-induced nephrotoxicity in humans, we examined kidney transplant biopsy records at our centre for all transplant(More)
Calciphylaxis is a rare and debilitating vasculopathy predominantly seen in patients with renal failure. The proposed mechanism of injury is active vascular calcification with associated elevated parathyroid hormone, hypercalcemia, or hyperphosphatemia. With improved pharmacologic agents including non-calcium containing phosphate binders, vitamin D(More)
One in nine adults in the United States has chronic kidney disease (CKD). Randomized studies show electronic health (e-health) systems improve health outcomes in chronic disease. This study describes a systematic evaluation of available CKD Web sites. We evaluated Web sites for educating patients with CKD, focusing on three specific design issues:(More)
Karyomegalic tubulointerstitial nephritis is a rare disease of uncertain etiology, which leads to progressive renal failure. Here, we report on a 39-year-old patient who presented with asymptomatic progressive decline of renal function. Two sequential renal biopsies demonstrated chronic tubulointerstitial nephritis with bizarre and dramatic enlargement of(More)
BACKGROUND Local television is the primary news source for the majority of Americans. This study aims to describe how local news reports on kidney disease. METHODS Using our searchable database of health-related late local news segments from 2002, we identified stories with the key words kidney, hypertension, blood pressure, or diabetes. This database is(More)
