Vitamin D modulates bisphosphonate (BP) efficacy, but its contribution to bone mineral density (BMD) after BP discontinuation is not known. To address this topic, we performed a retrospective analysis of postmenopausal women exposed to alendronate (ALN) to treat osteoporosis who regularly continued the supplementation of cholecalciferol or calcifediol at recommended doses. In the ninety-six recruited women (age 61.1 ± 6.9 years), ALN was administered for 31.2 ± 20.6 months and then discontinued for 33.3 ± 18.9 months. The modification of 25(OH)D serum levels over time was associated with a change of alkaline phosphatase (r = -0.22, = 0.018) and C-terminal collagen type 1 telopeptide (r = -0.3, = 0.06). Women in the tertile of the highest increase in 25(OH)D level showed a 5.7% BMD gain at lumbar spine, that was twice as great in comparison with participants with a lower 25(OH)D variation. At a multiple regression analysis, BMD change was associated with time since menopause (ß = 2.28, SE 0.44, < 0.0001), FRAX score for major fracture (ß = -0.65, SE 0.29, = 0.03), drug holiday duration (ß = -2.17, SE 0.27, < 0.0001) and change of 25(OH)D levels (ß = 0.15, SE 0.03, = 0.0007). After ALN discontinuation, improving the vitamin D status boosts the ALN tail effect on BMD.

Vitamin D is crucial for maintaining bone health and development, and bone mineral accumulation during childhood and adolescence affects long-term bone health. Vitamin D deficiency has been widely recognized as one of the main causes of osteoporosis and fractures, especially during the growth and development stage of children. Recent studies have shown that vitamin D deficiency may affect the deviation of bone development in children by mediating lipid metabolism disorders, but its specific mechanism of action has not been fully elucidated.

Background: Menopause driven decline in estrogen exposes women to risk of osteoporosis. Detection of early onset and silent progression are keys to prevent fractures and associated burdens.
Methods: In a discovery cohort of 120 postmenopausal women, we combined repeated quantitative pulse-echo ultrasonography of bone, assessment of grip strength and serum bone markers with mass-spectrometric analysis of exhaled metabolites to find breath volatile markers and quantitative cutoff levels for osteoporosis.

This study aims to develop and validate different radiomics models based on thoracic and upper lumbar spine in chest low-dose computed tomography (LDCT) to predict low bone mineral density (BMD) using quantitative computed tomography (QCT) as standard of reference. A total of 905 participants underwent chest LDCT and paired QCT BMD examination were retrospectively included from August 2018 and June 2019. The patients with low BMD (n = 388) and the normal (n = 517) were randomly divided into a training set (n = 622) and a validation set (n = 283).

Medium chained triglycerides (MCT) ketogenic diet is being extensively investigated for its neuroprotective effects against adverse effects associated with aging and neurodegenerative disorders. Aging is a common risk factor for the development of both osteoporosis and neurological disorders. Hence, suppression of aging and age-related neurodegeneration might contribute to delaying skeletal aging.

Purpose: The purpose of this study is to assess the effect of perioperative testosterone supplementation on orthopedic surgical outcomes.
Methods: Three online databases were searched from database inception until September 2024. Three reviewers independently screened all titles, abstracts, and full-texts of articles investigating perioperative testosterone use in orthopedic surgery.
