Bone resorption is regulated by various cytokines. In postmenopausal osteoporosis, bone loss due to estrogen deficiency is closely related to the production of bone-resorbing cytokine. Especially, the increased production of IL-1, IL-6 and TNF-α could induce the expression of RANKL in bone tissues to enhance osteoclastogenesis. Relationship between estrogen deficiency and various cytokines is important to clarify the pathogenesis of postmenopausal osteoporosis.

Osteoporosis increases fracture risk and reduces quality of life in menopausal women. Although physical activity, such as walking and bone joint exercise, is known to help maintain bone health, its effectiveness needs further examination. The aim of this study was to analyze the effects of physical activity, in particular walking and bone joint exercise, on enhancing bone remodeling in menopausal women.

Background: The associations between thyroid cancer and skeletal outcomes have not been thoroughly investigated. We aimed to investigate the risk of osteoporotic fractures in patients with thyroid cancer compared to that in a matched control group.

Methods: This retrospective cohort study included 2,514 patients with thyroid cancer and 75,420 matched controls from the Korean National Health Insurance Service-National Sample Cohort (NHIS-NSC, 2006-2019).

Fracture Prevention with Infrequent Zoledronate in Women 50 to 60 Years of Age.

N Engl J Med

January 2025

From the Department of Medicine, University of Auckland, Auckland, New Zealand (M.J.B., Z.N., A.M., C.G., V.P., B.M., A.G., I.R.R., G.G., A.H.); the Department of Psychology, Stanford University, Stanford, CA (C.G.); and the Department of Radiology, Starship Hospital, Auckland, New Zealand (S.B.).

Background: Zoledronate prevents fractures in older women when administered every 12 to 18 months, but its effects on bone density and bone turnover persist beyond 5 years. Whether infrequent zoledronate administration would prevent vertebral fractures in early postmenopausal women is unknown.

Methods: We conducted a 10-year, prospective, double-blind, randomized, placebo-controlled trial involving early postmenopausal women (50 to 60 years of age) with bone mineral density T scores lower than 0 and higher than -2.

Effect of romosozumab on bone mineral density and trabecular bone score in premenopausal women with low bone mass.

Osteoporos Int

January 2025

Department of Internal Medicine, Severance Hospital, Endocrine Research Institute, Yonsei University College of Medicine, 50-1 Yonsei-Ro, Seodaemun-gu, Seoul, 03722, Republic of Korea.

Unlabelled: We investigated the efficacy of romosozumab in premenopausal women with low bone mass. Romosozumab substantially increased bone mineral density and trabecular bone score in these women, aligning with its proven therapeutic benefits for postmenopausal osteoporosis.

Purpose: Romosozumab, an anti-sclerostin antibody, is a promising anabolic agent that increases bone formation and decreases bone resorption.

Background: Patients with Parkinson's disease (PD) and atypical parkinsonian syndromes are at increased risk of falls and should be actively screened and treated for osteoporosis. In 2024, the Royal Australian College of General Practitioners (RACGP) revised their practice guidelines for diagnosing and managing osteoporosis in postmenopausal women and men aged over 50 years.

Objective: We conducted the first Australian study to audit these guidelines in patients with PD and atypical parkinsonian syndromes.
