PURPOSE To determine the effect of supplementation with calcium citrate on circulating lipid concentrations in normal older women. SUBJECTS AND METHODS As part of a study of the effects of calcium supplementation on fractures, we randomly assigned 223 postmenopausal women (mean [+/- SD] age, 72 +/- 4 years), who were not receiving therapy for(More)
The central role of the multifunctional protein nephrin within the macromolecular complex forming the glomerular slit diaphragm is well established, but the mechanisms linking the slit diaphragm to the cytoskeleton and to the signaling pathways involved in maintaining the integrity of the glomerular filter remain incompletely understood. Here, we report(More)
BACKGROUND Perimenopausal and postmenopausal fractures are well-recognized, strong, independent predictors of subsequent fractures. However, it is unknown whether premenopausal fractures are predictive of postmenopausal fractures. OBJECTIVE To determine whether self-reported fractures sustained before the age of 50 years are associated with fractures(More)
AIM Treatment of vitamin D deficiency is an important aspect of the management of osteoporosis, particularly in the elderly. Most well-described regimens in current use involve daily dosing and thus require long-term compliance to be effective. In New Zealand, no preparation containing only low-dose vitamin D suitable for daily use is available. We describe(More)
The measurement of biochemical markers of bone turnover is integral to the diagnosis and management of Paget's disease. Recently, there has been a proliferation of new markers and a move to carry out existing assays on automated platforms. We have assessed the performance of seven currently available markers in 20 patients with Paget's disease undergoing(More)
Renal tubular reabsorption is important for extracellular fluid homeostasis and much of this occurs via the receptor-mediated endocytic pathway. This pathway is disrupted in Dent's disease, an X-linked renal tubular disorder that is characterized by low-molecular-weight proteinuria, hypercalciuria, nephrolithiasis, and renal failure. Dent's disease is due(More)
AIMS/HYPOTHESIS The role of peri-islet CD45-positive leucocytes, as one component of insulitis, in beta cell death during human type 1 diabetes remains unclear. We undertook a case study, comparing and quantifying leucocytes in the peri- and intra-islet areas in insulin-positive and -negative islets, to assess whether peri-islet leucocytes are pathogenic to(More)
Recently several studies in adolescent girls or premenopausal women have implicated the calcium sensing receptor (CASR) gene A986S polymorphism in calcium and bone metabolism. However, the role of this genetic variant in postmenopausal women, specifically the development of osteoporosis, is unknown. This study reports the findings of a randomized,(More)
OBJECTIVE To examine the factors influencing the levels of sex hormone-binding globulin (SHBG) in normal postmenopausal women by assessing the relationship between SHBG and measured anthropometric, metabolic and hormonal variables. DESIGN Cross-sectional, observational study. SUBJECTS AND METHODS Seventy normal postmenopausal women aged 47-71 years(More)
OBJECTIVE To prospectively assess bone density and the factors determining the rate of bone loss over a 10-year period of postmenopausal life. DESIGN Prospective, observational study. METHODS One hundred and four normal White postmenopausal women, baseline mean age 59 years (range 47-71 years) completed the study (mean duration of follow-up 10.2 years,(More)
