TL;DR: This was a preliminary case-control study to evaluate the potential diagnostic value of TBS as a complement to bone mineral density (BMD), by comparing postmenopausal women with and without fractures.

TL;DR: The World Health Organization FRAX tool improves targeting of pharmacologic therapy by combining clinical risk factors and estimating 10-yr fracture probability and it is suggested that the time has come for clinicians to consciously recognize muscle weakness as a risk factor for fracture.

TL;DR: There was high agreement between all DXA systems for estimation of BMC and body composition, and cross-calibration equations should be used to examine data across systems to avoid erroneous conclusions.

TL;DR: It can be concluded, in older women, that FFM is significantly correlated with BMD independently of height and fat mass, although the correlation was weaker when corrected for body weight.

TL;DR: Comparability of LDF measurements to other clinical and research bone density assessment modes, and enable assessment of BMD in children with disabilities, who are particularly prone to low trauma fractures of long bones, and for whom traditional DXA measurement sites are not feasible are demonstrated.

TL;DR: Until there is improved assay standardization and subsequent evidence-based consensus, it seems premature to recommend widespread screening 25(OH)D measurement, but selectively obtaining 25( OH)D measurements in individuals at clinical risk for vitamin D deficiency and/or those most likely to promptly experience benefits from supplementation seems appropriate.

TL;DR: Smaller bone size, and a strikingly lower muscle mass compared with men appear to underlie these findings.

TL;DR: RJL-BIA could be a valid method for assessing body composition of overweight/obese postmenopausal women once appropriate validated regression equations have been developed.

TL;DR: Mortality after osteoporotic hip fracture in Thais was extremely high, especially in the first year, about 8 times higher than that in the age-adjusted general population.

TL;DR: The benefits and limitations of the ISCD OPs are reviewed with emphasis on areas of controversy, including misunderstanding of the process used to establish them and the way that they are intended for use in clinical practice.

TL;DR: Two-thirds of professional cyclists had abnormally low BMD values, as measured by dual-energy X-ray absorptiometry Lunar DPX-NT, SV 4.0 in 23 professional male cyclists.

TL;DR: The contribution of body composition and strength variables to BMD varied by site as FM was more important for total body, forearm and spine BMD, and LBS exerted greater influence on the hip sites.

TL;DR: In COPD patients the risk of osteoporosis is high, in particular at severe stages of the disease, but seems to be due to traditional risk factors, such as older age, female gender, low BMI, history of smoking and fractures, GC treatment.

TL;DR: FRAX scores generated without T-scores may lead to treatmentRecommendations for patients who have normal bone mineral density and no treatment recommendations for patientsWho have osteoporosis.

TL;DR: Evaluated gender differences in total and regional body composition changes according to age and Tanner stage by dual-energy X-ray absorptiometry in Korean found females have lower android-gynoid percent fat ratio than males at Tanner stages 4 and 5 (p<0.01).

TL;DR: The precision for direct DXR was highly satisfactory both in vitro and in vivo, and values may differ between the radiographic equipment, and follow-up measurements should be performed with the same X-ray equipment.

TL;DR: This is a collection of scientific essays based on presentations and discussions at the 2008 Santa Fe Bone Symposium, held on August 1-2, 2008, in Santa Fe, New Mexico, USA.

TL;DR: Urgent strategies for the prevention and treatment of osteoporosis, and hence hip fracture, are needed.

TL;DR: In this article, the effect of anthropometry and biochemical parameters on peak bone density and its determinants in a healthy cohort of young adult male paramilitary personnel was evaluated by dual-energy X-ray absorptiometry in 473 healthy men aged 21-40 years.

TL;DR: Gender comparison showed significantly increased SOS values measured both at radius and at tibia in girls more than 13 yr of age compared with aged-matched boys, and subjects that spend more than 3h of daily "screen time" (television and personal computer) showed significantly decreased SOS valuesMeasurements of radius and tibial speed of sound showed a gradual increase of absolute values.

TL;DR: Overall, AA subjects had denser bones than CA subjects, but there were no racial differences in bone size, and the idea that higher hip fracture rates in women compared with men are associated with smaller bone size is supported.

TL;DR: Diagnostic criteria for postmenopausal osteoporosis using central dual-energy X-ray absorptiometry (DXA) T-scores have been widely accepted but the validity of these criteria for other populations, including premenopausal women and young men, has not been established.

TL;DR: DXA is a suitable tool to evaluate densitometric measurements at the mid-third part of the tibia and the influence of physical activity on that bone site and area, BMC, and BMD values were significantly higher in athletes compared with those of controls.

TL;DR: For longitudinal studies, the Stratec XCT 3000 can replace the XCT 2000 with minimal influence on bone and muscle parameters and Bland and Altman plots showed excellent agreement between instruments for all variables.

TL;DR: The prevalence of osteoporosis is high in all sites studied and is almost universal in the OF patients, seen even in young patients with less severe forms of the disease.

TL;DR: Both FM and FFM are important contributors to bone density although the balance of importance is slightly different between BMD and BMAD.

TL;DR: Sievänen's distal radius formulae were applied to derive indices of bone geometry, volumetric bone mineral density (vBMD), and strength from DXA data; results were compared to peripheral quantitative computed tomography (pQCT) output.

TL;DR: Findings indicate that ibandronate treatment preserves bone strength by maintaining good quality trabecular microarchitecture in women with postmenopausal osteoporosis.
