New long-distance audio/video and data communications links among health-care facilities promise to reduce rural patients' travel time and waiting time for subspecialty consultations. To offer a satisfactory alternative to face-to-face examination, the long-distance system must meet the subspecialty's minimum criteria. For pediatric cardiology in(More)
BACKGROUND Anti-angiogenic therapy targeted at vascular endothelial growth factor (VEGF) is now used to treat several types of cancer. We did a systematic review of randomized controlled trials (RCTs) to summarize the adverse effects of vascular endothelial growth factor inhibitors (VEGFi), focusing on those with vascular pathogenesis. METHODS AND(More)
Heparin is used as an interdialytic locking solution for hemodialysis (HD) central venous catheters (CVCs). The purpose of this study was to compare effectiveness of two heparin concentrations (10,000 and 1,000 U/mL) in preventing catheter malfunction. We compared two time periods: a 6-month period with heparin 10,000 U/mL and a 3-month period with heparin(More)
OBJECTIVE To investigate the interobserver reliability and diagnostic validity of a commercial electronic stethoscope for pediatric telecardiology. MATERIALS AND METHODS Pairs of blinded pediatric cardiologists made independent diagnoses, recommendations concerning follow-up echocardiography, and specific judgments regarding heart sounds, murmurs, and(More)
BACKGROUND Although primary care physicians (PCPs) are often responsible for the routine care of older adults with chronic kidney disease (CKD), there is a paucity of evidence regarding their perspectives and practice of conservative (non-dialysis) care. We undertook a qualitative study to describe barriers, facilitators and strategies to enhance(More)
