The impact of androgen deprivation therapy on bone microarchitecture in men with prostate cancer: A longitudinal observational study (The ANTELOPE Study).

Introduction: Androgen Deprivation Therapy (ADT) for prostate cancer (PC) has substantial negative impacts on the musculoskeletal system and body composition. Many studies have focused on the effects of ADT on areal bone mineral density (aBMD), but aBMD does not capture key determinants of bone strength and fracture risk, for example volumetric bone density (vBMD), geometry, cortical thickness and porosity, trabecular parameters and rate of remodelling. More specialist imaging techniques such as high-resolution peripheral quantitative computed tomography (HR-pQCT) have become available to evaluate these parameters.

Prolonged bone health benefits for breast cancer patients following adjuvant bisphosphonate therapy: the BoHFAB study.

Adjuvant bisphosphonates are often recommended in postmenopausal women with early breast cancer at intermediate-to-high risk of disease recurrence, but the magnitude and duration of their effects on bone mineral density (BMD) and bone turnover markers (BTMs) are not well described. We evaluated the impact of adjuvant zoledronate on areal BMD and BTMs in a sub-group of patients who had completed the large 5-yr randomized Adjuvant Zoledronic Acid to Reduce Recurrence (AZURE) trial. About 224 women (recurrence free) who had completed the AZURE trial within the previous 3 mo were recruited from 20 UK AZURE trial sites.

Bone remodeling and responsiveness to mechanical stimuli in individuals with type 1 diabetes mellitus.

Type 1 diabetes mellitus (T1DM) has been linked to increased osteocyte apoptosis, local accumulation of mineralized lacunar spaces, and microdamage suggesting an impairment of the mechanoregulation network in affected individuals. Diabetic neuropathy might exacerbate this dysfunction through direct effects on bone turnover, and indirect effects on balance, muscle strength, and gait. However, the in vivo effects of impaired bone mechanoregulation on bone remodeling in humans remain underexplored.

DXA-based statistical models of shape and intensity outperform aBMD hip fracture prediction: A retrospective study.

Areal bone mineral density (aBMD) currently represents the clinical gold standard for hip fracture risk assessment. Nevertheless, it is characterised by a limited prediction accuracy, as about half of the people experiencing a fracture are not classified as at being at risk by aBMD. In the context of a progressively ageing population, the identification of accurate predictive tools would be pivotal to implement preventive actions.

Fat, adipokines, bone structure and bone regulatory factors associations in obesity.

Context: Obese (OB) adults (BMI ≥ 30) have a higher bone mineral density (BMD) and more favourable bone microarchitecture than normal-weight (NW) adults (BMI 18.5-24.9).
