Validation of FRAX and the impact of self-reported falls among elderly in a general population: the HUNT study, Norway

AbstractSummaryFracture Risk Assessment Tool (FRAX) without bone mineral density (BMD) for hip fracture prediction was validated in a Norwegian population 50 –90 years. Fracture risk increased with higher FRAX score, and the observed number of hip fractures agreed well with the predicted number, except for the youngest and oldest men.Self-reported fall was an independent risk factor for fracture in women.IntroductionThe primary aim was to validate FRAX without BMD for hip fracture prediction in a Norwegian population of men and women 50 –90 years. Secondary, to study whether information of falls could improve prediction of fractures in the subgroup aged 70–90 years.MethodsData were obtained from the third survey of the Nord-Tr øndelag Health Study (HUNT3), the fracture registry in Nord-Trøndelag, and the Norwegian Prescription Database (NorPD), including 15,432 women and 13,585 men.FRAX hip without BMD was calculated, and hip fractures were registered for a median follow-up of 5.2  years.The number of estimated and observed fractures was assessed, ROC curves with area under the curve (AUC), and Cox regression analyses. For the group aged 70 –90 years, self-reported falls the last year before HUNT3 were included in the Cox regression model.ResultsThe risk of fracture increased with higher FRAX score. When FRAX groups were categorized in a 10-year percentage risk for hip fracture as follows,

AbstractSummaryWe found that the MRI T2* value is moderately negatively correlated with the bone mineral density assessed with quantitative computed tomography in evaluating osteoporosis in postmenopausal women and may have some potential in assessing severity of lumbar osteoporosis for scientific research.PurposeTo investigate the T2* quantitative measurement in magnetic resonance imaging (MRI) and its correlation with the bone mineral density (BMD) values evaluated with quantitative computed tomography (QCT) in women with postmenopausal lumbar vertebrae osteoporosis.Materials and methodsEighty-seven postmenopausal women ...

ConclusionOur simulations indicate that up to 50% reduction in radiation dose through sparse sampling can be used for FE-based prediction of femoral failure load. Sparse-sampled MDCT may allow fracture risk prediction and treatment monitoring in osteoporosis with less radiation exposure in the future.

AbstractBackgroundOsteoporosis is the most common condition contributing to 95% of fractures in older patients hospitalized for fracture treatment. Despite the significant impact of fragility fractures on patient morbidity and mortality, efforts in optimizing osteoporotic treatment and prevention remain inadequate. In contrast, in patients with limited life expectancy, withholding specific osteoporosis drug treatment appears reasonable. The threshold between under- and overtreatment is still unclear.MethodsIn 2016, we implemented a fracture liaison service (FLS) for 18  months to improve the quality of osteoporosis ca...

AbstractPurpose of ReviewThis review updates readers on recent developments in the assessment of cortical bone fragility in vivo. The review explains the clinical need that motivated the development of Cortical Bone Mechanics Technology ™ (CBMT) as a scientific instrument, its unique capabilities, and its necessary further development as a medical device.Recent FindingsClinical experience with dual-energy X-ray absorptiometry has led to calls for new clinical methods for assessing bone health. CBMT is a noninvasive, dynamic 3-point bending test that makes direct, functional measurements of the mechanical properties o...

ABSTRACTVitamin D (VitD) is commonly prescribed to normalise deficiencies and to treat osteoporosis. However, the effect VitD supplements have on skeletal muscle health is equivocal. While VitD is known to play a role in the various processes that maintain muscle integrity and function, recent studies utilising high bolus dose VitD supplementation has demonstrated an increased risk of falls. Thus, the aim of this study was to investigate the effects of high VitD supplementation on skeletal muscle function with and without exercise enrichment. Four ‐week old C57BL/10 mice (n = 48) were separated into either norm...
