Aseptic loosening and menopause‑induced osteoporosis are caused by an imbalance between bone formation and osteolysis. With an aging population, the probability of simultaneous occurrence of such conditions in an elderly individual is increasing. Strontium ranelate (SR) is an anti‑osteoporosis drug that promotes bone formation and inhibits osteolysis. The present study compared the effects of SR with those of the traditional anti‑osteoporosis drug alendronate (ALN) using an ovariectomized mouse model of osteolysis...

Purpose: Osteoporosis is asymptomatic morbidity of the elderly which develops slowly over several years. Osteoporosis diagnosis has typically involved Fracture Risk Assessment (FRAX) followed by dual energy X-ray absorptiometry (DXA) in specialist care. Point-of-care pulse-echo ultrasound (PEUS) was developed to overcome DXA-related access issues and to enable faster fracture prevention treatment (FPT) initiation. The objective of this study was to evaluate the cost-effectiveness of two proposed osteoporosis management (POMs: FRAX→PEUS-if-needed→DXA-if-needed→FPT-if-needed) pathways including PEUS compared with the current osteoporosis management (FRAX→DXA-if-needed→FPT-if-needed)...

Multiple Vertebral Fractures after Denosumab Discontinuation: How to Avoid Them? Abstract. Denosumab is a monoclonal antibody raised against the RANK ligand that inhibits the maturation and activity of osteoclasts. It decreases bone resorption, increases bone density and reduces fracture risk. However, after its discontinuation, a significant rebound effect appears that lasts about two years. It results in increased markers of bone remodeling, a loss of bone density that may be greater than gain, and an increased risk of multiple vertebral fractures...

Dysregulated Wnt signaling is associated with the pathogenesis of cancers, fibrosis, and vascular diseases. Inhibition of Wnt signaling has shown efficacy in various pre-clinical models of these disorders. One of the key challenges in developing targeted anti-cancer drugs is to balance efficacy with on-target toxicity. Given the crucial role Wnts play in the differentiation of osteoblasts and osteoclasts, acute inhibition of Wnt signaling is likely to affect bone homeostasis. In this study, we evaluated the skeletal effect of small molecule inhibitor of an o-acyl transferase porcupine (PORCN) that prevents Wnt signaling by blocking the secretion of all Wnts...

Many cancers such as human breast cancer and lung cancer easily metastasize to bones, leading to the formation of secondary tumors in advanced stage. Based on the CD44-targeted effect of oHA and bone-targeted effect of ALN, we prepared a reduction-responsive, CD44 receptor-targeting and bone-targeting nano-micelle, called CUR-loaded ALN-oHA-S-S-CUR micelles. In this study, we aimed to evaluate the antitumor activity and bone-targeting ability of CUR-loaded ALN-oHA-S-S-CUR micelles. The in vivo experiment results showed that a larger number of micelles was gathered in the bone metastatic tumor tissue and reduced the bone destruction...
