Lower peripheral quantitative computed tomography (pQCT)-derived leg muscle density has been associated with fragility fractures in postmenopausal women. Limb movement during image acquisition may result in motion streaks in muscle that could dilute this relationship. This cross-sectional study examined a subset of women from the Canadian Multicentre Osteoporosis Study. pQCT leg scans were qualitatively graded (1-5) for motion severity. Muscle and motion streak were segmented using semi-automated (watershed) and fully automated (threshold-based) methods, computing area, and density...

Patients with end-stage renal disease (ESRD) on maintenance hemodialysis (HD) exhibit osteoporosis and increased fracture risk. Dual-energy X-ray absorptiometry scan measurements and calculation of fracture risk assessment toll score underestimate fracture risk in these patients and do not estimate bone quality. Trabecular bone score (TBS) has been recently proposed as an indirect measure of bone microarchitecture. In this study, we investigated alterations of bone quality in patients with ESRD on HD, using TBS...

Identifying modifiable factors that influence bone status during adulthood to maximize bone quality is a potential primary strategy in the prevention of osteoporosis in later life. We investigated the impact of body height, body weight, body mass index, and body composition on calcaneal bone characteristics as measured with quantitative ultrasound in 441 Chinese adults (238 women) aged 20-55 yr from the middle areas of China. Body composition, including fat-free mass (FFM), muscle mass, and fat mass were obtained by bioelectrical impedance analysis...

In HIV-infected patients, combined antiretroviral therapy (cART) is associated to adipose tissue redistribution known as lipodystrophy and associated cardiometabolic risk. This study aimed to evaluate the evolution of body composition in HIV-infected patients, with and without lipodystrophy, over 2 yr. We evaluated anthropometric parameters and body composition by whole-body dual-energy X-ray absorptiometry in 144 HIV-infected patients on cART. We defined lipodystrophy by fat mass ratio. Lipodystrophy was present in 45...

Trabecular bone score (TBS) is a gray-level texture measure derived from lumbar spine dual-energy X-ray absorptiometry (DXA) images that predicts fractures independent of bone mineral density (BMD). Increased abdominal soft tissue in individuals with elevated body mass index (BMI) absorbs more X-rays during image acquisition for BMD measurement and must be accommodated by the TBS algorithm. We aimed to determine if the relationship between BMI and TBS varied between 2 major manufacturers' densitometers, because different densitometers accommodate soft tissues differently...

Polycystic ovary syndrome (PCOS) is an endocrine disorder affecting women of reproductive age manifesting with polycystic ovaries, menstrual irregularities, hyperandrogenism, hirsutism, and insulin resistance. The oligomenorrhea and amenorrhea characteristic to PCOS are associated with low bone mineral density (BMD); conversely, the hyperandrogenism and hyperinsulinemia may elicit a protective effect on BMD. As bone geometric properties provide additional information about bone strength, the objective of this study was to compare measures of hip geometry in women with PCOS to a healthy female population...

The aim of this study was to compare bone variables in active overweight/obese men and sedentary overweight/obese men. Thirty-seven active overweight/obese men and 45 sedentary overweight/obese men participated in this study. Weight and height were measured, and body mass index was calculated. Body composition and bone variables (bone mineral content [BMC], bone mineral density [BMD], geometric indices of hip bone strength, and trabecular bone score) were measured by DXA. Physical activity level, daily calcium intake, daily protein intake, and sleep duration were measured by validated questionnaires...

Osteoporosis is known as a degenerative disease of the skeletal system and its main complication is fracture, which influences quality of life in the elderly. There are 4 major blood groups in humans based on the presence of A and B antigens. According to the investigations, there are reported relations between blood types and some diseases. In this study, the association between the ABO blood group and the prevalence of osteoporosis and osteopenia in an elderly population was investigated. Medical records of 990 elderly people were investigated in a cross-sectional study and the association between their blood group and the incidence of osteoporosis and osteopenia was analyzed using SPSS version 17...

Osteoporosis is commonly perceived to be a disease confined to aging females, despite ongoing educational interventions. There are few data on the temporal change of dual-energy X-ray absorptiometry (DXA) use in aging males compared to females. Australian Medicare DXA claims between 1995 and 2015 were analyzed to investigate gender differences and temporal change of DXA use in males and females aged 45-85 yr. In females aged 45-54 and 55-64 yr, there was a progressive increase in DXA claims per capita between 1995 until 2002, with little subsequent change from 2002 to 2015 in the younger group, but a slow subsequent increase in females aged 55-64 yr...

Osteonecrosis of the jaw (ONJ) has been associated with antiresorptive therapy in both oncology and osteoporosis patients. This debilitating condition is very rare and advances in diagnosis and management may now effectively reduce the risk of its development and offer valuable treatment options for affected patients. This paper provides a case-based review of ONJ and application of the International Task Force on ONJ (referred to as the "Task Force") recommendations for the diagnosis and management of ONJ...

High-resolution peripheral quantitative computed tomography (HR-pQCT) quantifies bone microstructure and density at the distal tibia where there is also a sizable amount of myotendinous (muscle and tendon) tissue (MT); however, there is no method for the quantification of MT. This study aimed (1) to assess the feasibility of using HR-pQCT distal tibia scans to estimate MT properties using a custom algorithm, and (2) to determine the relationship between MT properties at the distal tibia and mid-leg muscle density (MD) obtained from pQCT...

This cross-sectional population-based study aimed to evaluate the relationships of muscle-mass and body-fat phenotypes to 10-yr risk of cardiovascular disease (CVD) events and eligibility for lipid management. Participants were Korean adults (N = 7315; 3163 men, 4152 women) aged 40-79 yr, free from stroke and coronary heart disease, who provided complete data for estimating 10-yr CVD risk and body composition during the Fifth Korea National Health and Nutrition Examination Survey (2009-2010). Four levels of combined muscle mass and body fat were determined using sex-specific quintiles of appendicular skeletal muscle mass divided by height squared, and sex-specific quintiles of total body fat percentage...

Current guidelines recommend bone mineral density (BMD) measurement in asymptomatic men above age 70 years and vertebral fracture (VF) assessment above 80 years with T-score <-1.0 with risk factors. We studied the prevalence of osteoporosis and morphometric VF in asymptomatic males aged 60 years and above in North India. Free-living community-dwelling men (n = 241, age: mean ± standard deviation 68.0 ± 6.2 years) underwent a detailed history, physical examination, biochemical evaluation, and BMD measurements at 3 sites: lumbar spine, total hip (TH), and femoral neck (FN)...

Berardinelli-Seip congenital lipodystrophy (BSCL) is a rare autosomal recessive syndrome characterized by a difficulty storing lipid in adipocytes, low body fat, hypoleptinemia, and hyperinsulinemia. We report here laboratory, bone mineral density (BMD), and bone mineral content findings of 21 patients (24.1 ± 8.4 yr old, 14 females, 18 diabetics, 5.3% total body fat) with BSCL. The mean leptin was very low (0.91 ± 0.42 ng/mL), and the mean values of the Z-scores for all studied sites were positive, except for the 33% radius (Z-score -0...
