'Magic formula' accurately predicts fracture risk in osteoporotic women
Researchers have developed a mathematic formula to predict a woman's risk of osteoporotic fracture. The equation has proved 75 percent accurate and will allow physicians to tailor their treatment strategies to help women prevent fractures of fragile bones. The study appears in the October issue of Radiology.

Estrens might not be the answer for osteoporosis
A new study appearing in the September issue of the Journal of Clinical Investigation indicates that caution might be needed if a new group of drugs known as estrens are to be developed for the treatment of osteoporosis. The researchers found that although estrens improved bone strength in mice with osteoporosis, they also had adverse effects on reproductive organs and human breast cancer cells.

Calcium-rich foods include milk, cheese, yoghurt, greens, broccoli, sardines, beans and peas. The mineral is added to many breakfast cereals, snack bars and drinks as manufacturers try to woo the parental market.

Growing body of research links lead to osteoporosis
Bolstered by recent laboratory findings, researchers at the University of Rochester Medical Center are embarking on a National Institutes of Health-funded clinical study to better understand the deceptive role environmental lead exposure plays in bone maturation and loss. The clinical trial is the latest in a growing body of research that is putting yet one more notch in the belt of diseases attributed to lead, and this time, researchers say, its target is older adults at risk for osteoporosis.

GENOMOS: Weak Links found between COL1A1 Polymorphism, BMD, and Fracture Risk
One out of every two women and one in eight men over 50 will have an osteoporosis-related fracture in their lifetime. Osteoporosis is characterized by low bone mass and structural deterioration of bone tissue, and often progresses without overt symptoms or pain until a bone breaks. Fractures occur typically in the hip, spine, and wrist. Currently, there is no accurate measure of overall bone strength. Bone mineral density (BMD) is frequently used as a proxy measure, but it can explain only a modest proportion of fracture risk.

Denosumab may show promise in the treatment of osteoporosis
Amgen (NASDAQ: AMGN), the world's largest biotechnology company, announced today the publication of Phase 2 data demonstrating twice-yearly injections of denosumab (previously referred to as AMG 162), a RANK Ligand inhibitor, significantly increased bone mineral density (BMD) in the total hip, lumbar spine, distal 1/3 radius and total body compared to placebo. The results of this one-year study appeared in the Feb. 23, 2006 issue of the New England Journal of Medicine. Data results also included an open-label FOSAMAX� (alendronate)* arm of the same clinical trial.

New insights into anti-osteoclastogenic action of vitamin D

Adequate Vitamin D Maintains Calcium Metabolism
Calcium intake levels of more than 800 mg/day may be unnecessary for maintaining calcium metabolism if vitamin D status is adequate, according to a study in the November 9 issue of JAMA. The importance of adequate vitamin D status for optimum bone health has received increased recognition in recent years, with higher recommended intake levels being proposed by some investigators, according to background information in the article. The ideal intake is not known, and different criteria have been proposed for estimating population requirements. Serum 25-hydroxyvitamin D has been the generally accepted indicator of vitamin D status, but no universal consensus has been reached regarding which serum values constitute sufficiency. An inverse relationship between serum 25-hydroxyvitamin D and serum parathyroid hormone (PTH) is well established. Parathyroid hormone is a major hormone maintaining normal serum concentrations of calcium and phosphate and is itself regulated through levels of calcitriol and serum calcium. An insufficiency of vitamin D or calcium is generally associated with an increase in PTH.

In fact, more than a third of patients who were thought to have low-risk injuries actually have additional damage that may include significant fractures with the potential to produce serious spinal problems if not detected and treated properly.

Serial bone mineral density (BMD) measurements can improve fracture risk accuracy
Scientists from the Garvan Institute of Medical Research in Sydney, Australia, are suggesting a new approach to determining the risk of fracture in individuals with the brittle bone disease, osteoporosis, which could have treatment implications. Their finding, published in the Journal of Bone and Mineral Research, is based on data from a fifteen-year epidemiology study and shows that calculating bone loss, by having at least two bone mineral density (BMD) measurements taken a minimum of 1-2 years apart, can improve the accuracy of fracture risk assessment.
