Vertebral fracture risk (VFR) score for fracture prediction in postmenopausal women
SUMMARY:
Early prognosis of osteoporosis risk is not only important to individual patients but is also a key factor when screening for osteoporosis drug trial populations. We present an osteoporosis fracture risk score based on vertebral heights. The score separated individuals who sustained fractu…

Is bone quality associated with collagen age?
The World Health Organization defines osteoporosis as a systemic disease characterized by decreased bone tissue mass and microarchitectural deterioration, resulting in increased fracture risk. Since this statement, a significant amount of data has been generated showing that these two factors do not…

The effects of oral calcitonin on bone collagen maturation: implications for bone turnover and quality
Anti-resorptive strategies may affect bone collagen maturation differently depending on the mode of action. Orally administrated calcitonin resulted in a dose dependent inhibition of bone resorption but did not change bone collagen maturation. This may reflect aspects of bone quality.

Bone turnover and bone collagen maturation in osteoporosis: effects of antiresorptive therapies
Bone collagen maturation may be important for anti-fracture efficacy as the reduction in risk is only partly explained by a concomitant increase in BMD during anti-resorptive therapy. Different treatments caused diverse profiles in bone collagen degradation products, which may have implications for …

Osteoclasts prefer aged bone
We investigated whether the age of the bones endogenously exerts control over the bone resorption ability of the osteoclasts, and found that osteoclasts preferentially develop and resorb bone on aged bone. These findings indicate that the bone matrix itself plays a role in targeted remodeling of age…

Assessment of osteoclast number and function: application in the development of new and improved treatment modalities for bone diseases
Numerous experimental and clinical observations suggest that overall changes in bone resorption during menopause or treatment with hormone replacement therapy (HRT) are combined effects of changes in osteoclast number and function. Moreover, due to a coupling between osteoclastic bone resorption and…
