NEW YORK (Reuters Health)—Various image analysis techniques show sex-specific patterns of bone deterioration at the hip, suggesting that men and women should be assessed differently for hip fracture risk, researchers say. “One major contribution of this work is the integration of data-driven computational anatomy approaches, which showed that proximal femur fragility linked to fracture seems…

The Right Load: Insights into Age-Impaired Mechanoadaptive Cortical Bone Response
Aging bones lose their ability to mechanoadapt, but new research suggests age-related adaptation failure may result from insufficient mechanical stimulus…
A Parathyroid Hormone Both Builds & Destroys Bone
SAN DIEGO—A hormone secreted by the parathyroid gland is both a builder and a destroyer of bone in humans, with important implications for a variety of conditions treated by rheumatologists. In the Oscar Gluck, MD, Memorial Lecture at the 2017 ACR/ARHP Annual Meeting Nov. 3–8, Henry Kronenberg, MD, chief of the Endocrine Division at Massachusetts…
3 Experts Discuss Bone Health
SAN DIEGO—At the 2017 ACR/ARHP Annual Meeting Nov. 3–8, experts discussed improving bone health in the U.S., gave tips on bone health disorders in pediatrics and reviewed new translational science findings for joint conservation in early osteonecrosis. E. Michael Lewiecki, MD, director of the New Mexico Clinical Research & Osteoporosis Center in Albuquerque, N.M., called…
Baseline Bone Measures Predict Risk of Fragility Fracture in Postmenopausal
NEW YORK (Reuters Health)—Baseline measures of bone density, microarchitecture and strength predict the risk of fragility fractures in postmenopausal women, according to results from the Calgary CaMOS cohort. Changes in bone health were not associated with fracture risk, however, said Dr. Lauren A. Burt from the University of Calgary, Canada, who worked on the study….
Changes in Bone Markers Predict Fracture Reduction with Anti-Resorptive Drug
NEW YORK (Reuters Health)—Treatment-related changes in bone formation markers predict vertebral-fracture reduction with anti-resorptive drug therapy, according to a meta-regression analysis of 14 clinical trials. “These results may be useful for the development of new osteoporosis treatments or when considering new populations or dosing regimens with existing treatments,” Dr. Douglas C. Bauer from the University…
MIF Cytokine May Impact Inflammation, Bone Formation in Ankylosing Spondylitis
What factors drive inflammation and progressive disease in ankylosing spondylitis (AS)? The answers have long eluded rheumatologists. Although 90% of patients with AS test positive for the HLA-B27 gene, pieces remain missing in our understanding of this chronic, inflammatory disease, which often leads to pain, spinal fusion and, in about half of patients, gut involvement,…
New Data May Explain the Role of Sclerostin in Bone Formation
New research in mice shows that sclerostin deficiency may play a significant role in bone formation, possibly despite skeletal age. In the study, sclerostin-deficient mice more readily formed cortical bone and had increases in periosteal bone formation rates, as well as increased expression of the Wnt inhibitor Dkk1, than controls…
Novel Bone Drug Promising in Postmenopausal Osteoporosis
NEW YORK (Reuters Health)—The investigational drug romosozumab led to gains in hip bone mineral density (BMD) that were not seen with teriparatide in older women with osteoporosis transitioning from bisphosphonate therapy in the STRUCTURE study. Amgen’s romosozumab is a monoclonal antibody that inhibits sclerosin, a negative regulator of bone formation. In addition to stimulating bone…
U.S. Senate Mulls Bare-Bones Healthcare Bill; Marathon of Voting Expected
WASHINGTON (Reuters)—U.S. Senate Republicans embarked on Thursday on another push to unravel Obamacare, working on a stripped-down bill after failing to pass broader legislation and complete a seven-year campaign to gut a law that extended health coverage to millions. Republicans leaders hope a so-called skinny bill can draw enough votes to pass despite unified Democratic…
