TL;DR: BTM hold promise in fracture risk prediction and for monitoring treatment and Uncertainties over their clinical use can be in part resolved by adopting international reference standards.

TL;DR: Sex hormone concentrations were strongly associated with several established or suspected risk factors for breast cancer, and may mediate the effects of these factors on breast cancer risk.
Journal ArticleDOI
Effects of skin thickness, age, body fat, and sunlight on serum 25-hydroxyvitamin D.
TL;DR: The results suggest that the tendency for serum 25(OH)D to fall with age is due in part to the age-related decline in skin thickness.
Journal ArticleDOI
HYDROXYLASE ENZYMES OF THE VITAMIN D PATHWAY: Expression, Function, and Regulation
TL;DR: Vitamin D is a secosteroid that is metabolically activated and degraded through the actions of three cytochrome P450 hydroxylase enzymes, resulting in synthesis of the pleiotropic hormone 1,25-dihydroxyvitamin D (1,25VD), which regulates over 60 genes whose actions include those associated with calcium homeostasis and immune responses as well as cellular growth, differentiation, and apoptosis.
Journal ArticleDOI
International Osteoporosis Foundation and International Federation of Clinical Chemistry and Laboratory Medicine position on bone marker standards in osteoporosis.
Samuel D Vasikaran,Cyrus Cooper,Richard Eastell,Andrea Griesmacher,Howard A. Morris,Tommaso Trenti,John A. Kanis +6 more
TL;DR: The IOF/IFCC recommends one bone formation marker and one bone resorption marker to be used as reference markers and measured by standardised assays in observational and intervention studies to enlarge the international experience of the application of markers to clinical medicine and to help resolve uncertainties over their clinical use.
