Quantitative ultrasound (QUS) has emerged as an engineering technology for monitoring bone quantity and quality. It has been shown to correlate well to both fracture risk and mechanical properties. Bone loss in space in zero-gravity is known to be rapid (e.g., approximately 2% per month in average) and leads to increased fracture risk and longer earth-bound recovery periods. The current researc...

the akhal-teke is an ancient horse originat-ing from asia where it was used by nomadic tribes and used as a warhorse. lameness examinations require proper interpretation of clinical and radiographic findings. therefore, understanding of normal radiographic findings of the foot is necessary. although the radiographic appearance of the normal foot must be understood to recognize abnormalities ,th...

BACKGROUND The objective of this study was to investigate if application of United Kingdom National Osteoporosis Society (UK-NOS) triage approach, using calcaneal quantitative ultrasound (QUS), phalangeal radiographic absorptiometry (RA), or both methods in combination, for identification of women with osteoporosis, would reduce the percentage of women who need further assessment with Dual Ener...

The aim of this study was to establish reference data for the quantitative ultrasound (QUS) of the calcaneus and for the bone mineral densities (BMD) of the calcaneus and distal forearm, and to evaluate the correlation between QUS parameters and BMD in a Korean population. We performed a cross-sectional study involving 3,053 subjects (1,225 men and 1,828 women). QUS was conducted on the calcane...

OBJECTIVE To estimate the effect of demographic, social, behavioural and anthropometric factors on quantitative ultrasound (QUS) parameters in an urban population. METHODS Cross-sectional evaluation of consecutive subjects selected as part of the EPIPorto study, Portugal. Information was obtained on demographic, social, clinical and behavioural characteristics using a standard protocol. Calca...

Sedentary lifestyle contributes to osteoporosis and fragility fracture risks among modern humans, but whether such risks are prevalent in physically active preindustrial societies with lower life expectancies is unclear. Osteoporosis should be readily observable in preindustrial societies if it was regularly experienced over human history. In this study of 142 older adult Tsimane forager-hortic...

As an emerging alternative to current radiation-based bone densitometry techniques, there is a growing interest in the use of quantitative ultrasound (QUS) measurements for the noninvasive assessment of fracture risk in the management of osteoporosis. However, there are also a multiplicity of technologically different QUS devices available on the market and, so far, no study has compared heel a...

Background: A better understanding of how bone mineral density and vitamin D levels are associated with femoralneck and intertrochanteric hip fractures may help inform healthcare providers. We asked: 1) In patients age ≥ 55 years,is there a difference in quantitative ultrasound of the heel (QUS) t-score between patients with fractures of the femoralneck and those with fractures of the intertroc...

INTRODUCTION The results of studies examining the influence of subclinical hypothyroidism (SCH) and levothyroxine (L-T4) replacement therapy on bone have generated considerable interest but also controversy. The present research aims to evaluate the effects of L-T4 treatment on different skeletal sites in women. MATERIAL AND METHODS A group of 45 premenopausal (mean age: 43.62 ±6.65 years) an...
