The diagnosis of osteoporosis
TL;DR: This paper summarizes issues and proposes diagnostic criteria for osteoporosis for practical use and addresses a number of problems which need to be addressed in adapting a conceptual definition for clinical use.
Journal ArticleDOI

TL;DR: A microsatellite within intron 3 of the transcription factor 7–like 2 gene (TCF7L2; formerly TCF4) was associated with type 2 diabetes mellitus and is thought to act through regulation of proglucagon gene expression in enteroendocrine cells via the Wnt signaling pathway.
Journal ArticleDOI
Effects of raloxifene on bone mineral density, serum cholesterol concentrations, and uterine endometrium in postmenopausal women.
Pierre D. Delmas,Nina H. Bjarnason,Bruce H. Mitlak,Anne-Catherine Ravoux,Aarti Shah,William J. Huster,Draper Michael William,Claus Christiansen +7 more
TL;DR: Daily therapy with raloxifene increases bone mineral density, lowers serum concentrations of total and low-density lipoprotein cholesterol, and does not stimulate the endometrium.
Journal ArticleDOI
Effects of oral ibandronate administered daily or intermittently on fracture risk in postmenopausal osteoporosis.

TL;DR: This is the first study to prospectively show antifracture efficacy for the intermittent administration of a bisphosphonate in osteoporotic women with prevalent vertebral fracture.
Journal ArticleDOI

TL;DR: A genome-wide association study for type 2 diabetes (T2D) in Icelandic cases and controls is conducted, and it is found that a previously described variant in the transcription factor 7-like 2 gene (TCF7L2) gene conferred the most significant risk.
