ABSTRACT Introduction: Use of androgen deprivation therapy (ADT) in carcinoma prostate (CaP) has deleterious effect on bone mineral density (BMD) leading to increase incidence of osteoporosis and skeletal-related events. We evaluated bone health status and impact of bone-directed therapy (BDT) and ADT on BMD in these patients from Jan 2015-Dec 2018. Materials and Method: Baseline bone health was assessed using Tc-99 MDP Bone scan/ DEXA scan for patients on ADT. Monthly zoledronic acid (ZA) was given to high-risk candidates (T-score ≤ 2.5 or previous hip/vertebral fracture) or Skel et al. metastatic patients who were rec...

ABSTRACTAlthough strong evidence exists that certain activities can increase bone density and structure in people, it is unclear what specific mechanical factors govern the response. This is important because understanding the effect of mechanical signals on bone could contribute to more effective osteoporosis prevention methods and efficient clinical trial design. The degree to which strain rate and magnitude govern bone adaptation in humans has never been prospectively tested. Here, we studied the effects of a voluntary upper extremity compressive loading task in healthy adult women during a 12 ‐month prospective perio...

This study was performed in 886 elderly men from the Swedish cohort of the Osteoporotic Fractures in Men (MrOS) study. Urinary samples, bone mineral density (BMD), smoking data, and other background information were obtained at baseline in 2002–2004. Urinary cadmium was analyzed in baseline samples and adjusted for creatinine. The cohort was followed up until August 2018 for fracture incidence, based on the X‐ray register. Medi ation analysis was conducted to evaluate the indirect effect (via cadmium) of smoking on both BMD and fractures. Time to first fracture was analyzed using the accelerated failure time (AFT) ...

ABSTRACTInvestigations into the effects of bone ‐targeted exercise programs on musculoskeletal health and function in men are limited. The purpose of the Lifting Intervention For Training Muscle and Osteoporosis Rehabilitation for Men (LIFTMOR‐M) trial was to examine the efficacy and safety of two novel, supervised, eight‐month, twice‐wee kly exercise programs in middle‐aged and older men with low BMD. Men with low proximal femur and/or LS BMD were recruited and randomized to high‐intensity progressive resistance and impact training (HiRIT) or machine‐based isometric axial compression (IAC). Intervention resp...

This study assessed whether MBBF in the femoral neck (FN) is preserve d in the context of inhibited remodeling in subjects receiving denosumab.This open ‐label study enrolled postmenopausal women with osteoporosis who had received ≥2 doses of denosumab (60 mg subcutaneously Q6M) per standard of care and were planning elective total hip replacement (THR) owing to osteoarthritis of the hip. Transverse sections of the FN were obtained after THR and analyzed histomorphometrically. MBBF, based on fluorochrome labeling and presence of smooth cement lines, was evaluated in cancellous, endocortical, and periosteal envelopes o...

ABSTRACTSeveral epidemiological studies have reported a relationship between statin treatment and increased bone mineral density (BMD) and reduced fracture risk, but the mechanism underlying the purported relationship is unclear. We used Mendelian randomization (MR) to assess whether this relationship is explained by a specific effect in response to statin use or by a general effect of lipid lowering. We utilized 400 single ‐nucleotide polymorphisms (SNPs) robustly associated with plasma lipid levels as exposure. The outcome results were obtained from a heel estimated BMD (eBMD) genomewide association study (GWAS) from t...

ABSTRACTIn the growing skeleton, angiogenesis is intimately coupled with osteogenesis. Chronic, high doses of glucocorticoids (GCs) are associated with decreased bone vasculature and induce osteoporosis and growth failure. The mechanism of GC ‐suppression of angiogenesis and relationship to osteoporosis and growth retardation remains largely unknown. Type H vessels, which are regulated by preosteoclast (POC) platelet‐derived growth factor–BB (PDGF‐BB), are specifically coupled with bone formation and development. We determined th e effect of GCs on POC synthesis of PDGF‐BB in relation to type H vessel formati...

CONCLUSIONS: The correlation between increase of inflammatory markers and increased risk of osteoporotic fractures and the lack of difference between Crohn's disease and ulcerative colitis suggest a central role of inflammation over malabsorption in this population.

(International Osteoporosis Foundation) As globally active organizations in the musculoskeletal field, the International Osteoporosis Foundation (IOF) and the Fragility Fracture Network (FFN) have complementary visions and missions dedicated to reducing the fragility fracture burden for the benefit of patients and healthcare systems worldwide. A new collaboration agreement between the organizations will help to optimize and strengthen their common mission, setting the framework for greater collaboration, joint opportunities, and optimization of resources.
