OBJECTIVES To review and synthesize the literature in the following areas: the association of specific circulating 25(OH)D concentrations with bone health outcomes in children, women of reproductive age, postmenopausal women and elderly men; the effect of dietary intakes (foods fortified with vitamin D and/or vitamin D supplementation) and sun exposure on(More)
Osteoporosis is the most common cause of fragility fractures. Bone remodelling is essential for repairing damaged areas within bone to preserve bone strength and for assisting in mineral homeostases. In young adults, bone remodelling is usually balanced with approximately as much bone replaced as is removed during each remodelling cycle. However, when(More)
BACKGROUND Many residents of the United States and Canada depend on dietary sources of vitamin D to help maintain vitamin D status. Because few natural food sources contain vitamin D, fortified foods may be required. OBJECTIVE We aimed to determine the effects of vitamin D-fortified foods on serum 25-hydroxyvitamin D [25(OH)D] concentrations. DESIGN We(More)
BACKGROUND Serum creatinine concentration is an inadequate screening test for chronic kidney disease, especially in elderly patients. We hypothesized that laboratory reporting of estimated glomerular filtration rate (GFR) accompanied with an educational intervention would improve recognition of chronic kidney disease (CKD). METHODS We conducted a(More)
This study's aim was to develop and pilot test an evidence-based decision aid for postmenopausal women with osteoporosis who are considering options to prevent fractures. The aid was based on the Ottawa Decision Support Framework, and integrated evidence from our Cochrane systematic reviews. Following development by a panel of experts in osteoporosis and(More)
BACKGROUND Troponin T (cTnT) and troponin I (cTnI) are present in the sera of some heart failure (HF) patients and have potential importance as prognostic markers. OBJECTIVE To prospectively evaluate the prognostic value of cTnT and cTnI in well-characterized HF patients and clarify their relationship to other clinical markers of HF severity. METHODS(More)
The optimal frequency of intravenous (IV) bisphosphonate administration is unclear. We thus performed a study evaluating the effects of switching from 3–4 to 12 weekly therapy in patients with biochemically defined low-risk bone metastases. Patients with serum C-telopeptide (CTx) levels ≤600 ng/L after ≥3 months of 3–4 weekly IV pamidronate were switched to(More)
OBJECTIVES To determine the sensitivity of the venous lactate level at presentation for acute myocardial infarction (AMI) in emergency department (ED) patients with chest pain. METHODS A prospective, double-blind observational study was done in a tertiary care ED. From January to April 2000, all consecutive patients presenting with chest pain were(More)
1110 CLINICAL CHEMISTRY, Vol. 30, No. 6, 1984 the 19 with albumin values 36 g/L had low FF4 values by GC2 and after chart review were classified as patients with nonthyroidal illness, a condition in which one can observe low FF4 values with normal or slightly abovenormal thyrotropin (8). In addition, we noted that 10 of the 15 patients with albumin >36 g/L(More)
