Article Abstract
Purpose Of Review: The aim of treatment in patients at high risk for fractures is to reduce the risk of a first or a subsequent fracture. New data are available on the antifracture effects and side-effects of antiresorptive and osteoanabolic drugs, and new emerging therapies with new modes of action are on the horizon.
Recent Findings: Calcium and vitamin D intake should be sufficient, but not too high. Vertebral, nonvertebral (including hip fracture) prevention with antiresorptive drugs such as bisphosphonates (alendronate, risedronate and zoledronic acid) and denosumab exceeds the risk of rare side-effects such as atypical femur fracture and osteonecrosis of the jaw. Teriparatide is an osteoanabolic drug that improves quality of life in severe osteoporosis. Strontium ranelate decreases dynamic parameters of bone formation during the first year of treatment, and could increase the risk of cardiovascular events in high-risk patients. Initiation of and adherence to fracture prevention drugs are still low. New potential developments in antiresorptive drugs include odanacatib, a selective inhibitor of cathepsin K, and, in osteoanabolic drugs, monoclonal antibodies against sclerostin.
Summary: These recent data indicate that fracture prevention with antiresorptives and teriparatide is effective with a reasonable safety profile. Odanacatib and antisclerostin are promising new drugs with new mechanisms of action, as they are able to disconnect the normal coupling between bone resorption and bone formation.

Lee's TRIAD-osteoporosis, fragility fracture, and bone health optimization.
Arch Osteoporos
January 2025
Beacon Hospital, 1, Jalan 215, Section 51, Off Jalan Templer, 46050, Petaling Jaya, Selangor, Malaysia.
Unlabelled: Osteoporosis, fragility fractures, and bone health optimization share the same pathophysiology, diagnostic tools, risk assessment, and treatments. Grouping them into "Lee's TRIAD" allows surgeons and physicians to collaborate more efficiently, using unified principles and strategies for managing these conditions.
Purpose: The primary goal of osteoporosis management is to prevent fragility fractures, which occur from falls from standing height or less in individuals over fifty.
Are Dietary Patterns Relevant for Reducing the Risk of Fractures and Sarcopenia?

Purpose Of Review: This review aims to summarise recent evidence on the effects of dietary patterns on the risk of bone fractures and sarcopenia.
Recent Findings: Several dietary patterns have been investigated in relation to musculoskeletal health, including Mediterranean Dietary Patterns (MDP), Dietary Inflammatory Indices, vegetarian and vegan diets. Adherence to 'healthier' dietary patterns appears to be protective against fractures and sarcopenia, with the strongest protective associations found between the MDP and fractures.
Early and multiple doses of zoledronate mitigates rebound bone loss following withdrawal of RANKL inhibition.

Rebound bone loss following denosumab discontinuation is an important barrier in the effective long-term treatment of skeletal disorders. This is driven by increased osteoclastic bone resorption following the offset of RANKL inhibition, and sequential osteoclast-directed therapy has been utilised to mitigate this. However, current sequential treatment strategies intervene following the offset of RANKL inhibition and this approach fails to consistently prevent bone loss.

Chronic exposure to stress has been considered a risk factor for hypertension, which is also associated with increased bone resorption. This review aimed to investigate the effect of acute and chronic stress, associated with hypertension, on the skeletal system. A comprehensive search was conducted across multiple databases, focusing on peer-reviewed articles published in English.

This Therapeutic Letter considers the evidence for inhaled corticosteroids (ICS) as a treatment for Chronic Obstructive Pulmonary Disease (COPD). Drug therapy aims to alleviate symptoms, enhance functional capacity and prevent exacerbations, but has not consistently shown to reduce mortality or improve quality of life based on randomised trials.Inhaled corticosteroids have shown limited benefits for COPD symptoms and exacerbations but increased risks of serious harms.
