Direct Comparison of the Precision of the New Hologic Horizon Model With the Old Discovery Model
Previous publications suggested that the precision of the new Hologic Horizon densitometer might be better than that of the previous Discovery model, but these observations were confounded by not using the same participants and technologists on both densitometers. We sought to study this issue methodically by measuring in vivo precision in both densitometers using the same patients and technologists. Precision studies for the Horizon and Discovery models were done by acquiring spine, hip, and forearm bone mineral density twice on 30 participants. (Source: Journal of Clinical Densitometry)

Proceedings of the 2017 Santa Fe Bone Symposium: Insights and Emerging Concepts in the Management of Osteoporosis
The 18th Annual Santa Fe Bone Symposium was held on August 4 –5, 2017, in Santa Fe, New Mexico, USA. The symposium convenes health-care providers and clinical researchers to present and discuss clinical applications of recent advances in research of skeletal diseases. The program includes lectures, oral presentations by endocrinology fellows, case-based pan el discussions, and breakout sessions on topics of interest, with emphasis on participation and interaction of all participants. Topics included the evaluation and treatment of adult survivors with pediatric bone diseases, risk assessment and management of atypical fe...

Adaptive Bone Remodeling With New Design of the ABG Stem. Densitometric Study
To establish the pattern of bone remodeling caused by a cementless, anatomic implant, we intend to evaluate the changes in bone mineral density observed after surgery in the Gruen zones. A controlled, prospective study was carried out, in which a group of 37 patients with primary coxarthrosis were densitrometrically analyzed over the 1 year period following the implant of an ANATO stem (Stryker). The patient's healthy hip was taken as the control. Any differences in the remodeling pattern were compared according to age, body mass index, and implant size.

The Prediction of Body Composition in African Americans From Spine and Hip Dual-Energy Absorptiometry
Body composition, the makeup of the body's fat and lean tissue, is associated with important health outcomes and provides useful clinical information. Although body composition can be measured with total body dual-energy X-ray absorptiometry (DXA), this is rarely performed. As an alternative to total body DXA measurement, methods for estimation of body composition have been developed. These methods use soft tissue measures from spine and hip DXA to predict body composition and include prediction equations previously published by Leslie and proprietary equations within General Electric densitometry software.

Effects of Contrast Enhancement on In-Body Calibrated Phantomless Bone Mineral Density Measurements in Computed Tomography
We aimed to test the potential of phantomless volumetric bone mineral density (PLvBMD) measurements for the determination of volumetric bone mineral density (vBMD) in routine contrast-enhanced computed tomography (CECT). We evaluated 56 tri-phasic abdominal computed tomography scans, including an unenhanced scan as well as defined CECT scans in the arterial and portalvenous phase. PLvBMD analysis was performed by 4 radiologists using an FDA-approved tool for phantomless evaluation of bone density (IntelliSpace, Philips, The Netherlands).

Dual-energy X-ray Absorptiometry Quality Matters
Errors in radiologic tests occur (1 –3). However, there is a clinical perception among osteoporosis specialists that errors in dual-energy X-ray absorptiometry (DXA) performance and reporting are extremely common (4,5) and recent evidence reinforces this belief (6–8). These errors are not inconsequential, and they have the potenti al to cause inappropriate clinical management (9), potentially affecting up to 40% of patients in 1 report (7). Possible reasons for such a high error rate include a decline in DXA reimbursement (10), the belief that DXA can be automated with results requiring no human oversight, and failure ...

The Relevance of Osteoclastic and Osteoblastic Activity Markers Follow-Up in Patients on Antiresorptive Osteoporosis Treatment
In general, markers of bone formation and markers of bone resorption are changing synergistically, so the monitoring of any osteoclastic and any osteoblastic marker should reflect the rate of bone transformation. The aim of the study is to monitor the bone metabolism markers in postmenopausal women with osteoporosis and osteopenia along with the variations caused by the effects of bisphosphonate therapy. The study involved 55 women of average age of 57.95 years, with osteopenia or osteoporosis. The patients with osteoporosis were treated with bisphosphonates (75  mg once a week); the laboratory tests were performed befor...
