Association between speed of sound of calcaneal bone assessed by quantitative ultrasound and sarcopenia in a general older adult population: A cross-sectional study. J Orthop Sci 2019; 24:906-911. [PMID: 30733130 DOI: 10.1016/j.jos.2019.01.003] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/23/2018] [Revised: 12/28/2018] [Accepted: 01/09/2019] [Indexed: 12/18/2022]
Abstract
BACKGROUND Lower calcaneal speed of sound may be related to sarcopenia because sarcopenia and osteopenia/osteoporosis show a linked relationship in older adults. The purpose of this study is to clarify whether the speed of sound of calcaneal bone assessed by quantitative ultrasound is associated with sarcopenia in a community-dwelling older adult population. METHODS This was a cross-sectional observational study. The participants in the study were recruited from a group of individuals who had registered for an annual town-sponsored medical check-up. The inclusion criteria for participation in the study were (1) aged older than 40 years, (2) living independently, and (3) able to walk without assistance. Those who had nursing care insurance were excluded. Four hundred sixty-seven residents (182 men, 285 women) were registered in the study. Demographic information, fall history, muscle mass index, grip strength, and gait speed were assessed. The speed of sound through the calcaneal bone was evaluated using a CM-200 sonometer. The assessment for sarcopenia is based on the recommendations of the Asian Working Group for Sarcopenia. RESULTS Speed of sound was positively correlated with muscle mass index and gait speed in men, and was positively correlated with grip strength and gait speed in women, when adjusted for age and body mass index. In a multivariate logistic regression analysis adjusted for age and sex and other confounders, speed of sound was independently related with lower gait speed and sarcopenia in women. Speed of sound under 1470.5 m/sec had discriminated for sarcopenia in females. CONCLUSION We propose that the speed of sound of calcaneal bone may be used to screen for sarcopenia in women. Sarcopenia should be considered if the speed of sound value is less than 1470.5 m/s in older women.

A Cross-Sectional Study of the Association between Autoantibodies and Qualitative Ultrasound Index of Bone in an Elderly Sample without Clinical Autoimmune Disease. J Immunol Res 2018; 2018:9407971. [PMID: 29854851 PMCID: PMC5952466 DOI: 10.1155/2018/9407971] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2017] [Revised: 03/05/2018] [Accepted: 03/17/2018] [Indexed: 12/15/2022] Open
Abstract
Bone loss is characteristic of the ageing process and a common complication of many autoimmune diseases. Research has highlighted a potential role of autoantibodies in pathologic bone loss. The confounding effects of immunomodulatory drugs make it difficult to establish the contribution of autoantibodies amongst autoimmune disease sufferers. We attempted to examine the relationship between autoantibodies and bone mass in a population of 2812 elderly participants without clinical autoimmune disease. Serum samples were assayed for a panel of autoantibodies (anti-nuclear, extractable nuclear antigen, anti-neutrophil cytoplasmic, thyroid peroxidase, tissue transglutaminase, anti-cardiolipin, rheumatoid factor, and cyclic citrullinated peptide). Bone mass was measured using quantitative ultrasound (QUS) of the calcaneus. The relationship between each autoantibody and bone mass was determined using linear regression models. Anti-nuclear autoantibodies were the most prevalent, positive in approximately 11%, and borderline in roughly 23% of our sample. They were also the only autoantibody observed to be significantly associated with QUS index in the univariate analysis (n = 1628; r = -0.20; 95% CI: -0.40-0.00; p = 0.046). However, statistical significance was lost after adjustment for various other potential confounders. None of the other autoantibodies was associated with QUS index in either univariate or multivariate analysis. We are limited by the cross-sectional nature of the study and the low prevalence of autoantibodies in our nonclinical sample.

Abstract
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. Bivariate correlation analysis demonstrated a significant negative correlation between age and broadband ultrasound attenuation (BUA), speed of sound (SOS), and stiffness index (SI) both in men (r = -0.177, p < 0.05; r = -0.499, p < 0.001; r = -0.530, p < 0.001, respectively) and women (r = -0.344, p < 0.001; r = -0.336, p < 0.001; r = -0.369, p < 0.001, respectively). Body height, body weight, FFM, and muscle mass had positive correlations with BUA, SOS, and SI in both genders, with FFM having the strongest correlation with BUA, SOS, and SI in men (r = 0.351, p < 0.001; r = 0.391, p < 0.001; r = 0.406, p < 0.001, respectively) and women (r = 0.331, p < 0.001; r = 0.288, p < 0.001; r = 0.324, p < 0.001, respectively). Fat mass had a positive correlation with BUA (r = 0.331, p < 0.001), SOS (r = 0.288, p < 0.001), and SI (r = 0.324, p < 0.001) in women, which was not found in men. Multivariate regression analysis revealed that, in both genders, FFM was a positive predictor for all 3 quantitative ultrasound variables.

Abstract
Purpose/introduction The present study investigates potential associations between liquid chromatography-mass spectrometry (LC-MS) measured sex hormones, dehydroepiandrosterone sulphate, sex hormone-binding globulin (SHBG) and bone ultrasound parameters at the heel in men and women from the general population. Methods Data from 502 women and 425 men from the population-based Study of Health in Pomerania (SHIP-TREND) were used. Cross-sectional associations of sex hormones including testosterone (TT), calculated free testosterone (FT), dehydroepiandrosterone sulphate (DHEAS), androstenedione (ASD), estrone (E1) and SHBG with quantitative ultrasound (QUS) parameters at the heel, including broadband ultrasound attenuation (BUA), speed of sound (SOS) and stiffness index (SI) were examined by analysis of variance (ANOVA) and multivariable quantile regression models. Results Multivariable regression analysis showed a sex-specific inverse association of DHEAS with SI in men (Beta per SI unit = − 3.08, standard error (SE) = 0.88), but not in women (Beta = − 0.01, SE = 2.09). Furthermore, FT was positively associated with BUA in men (Beta per BUA unit = 29.0, SE = 10.1). None of the other sex hormones (ASD, E1) or SHBG was associated with QUS parameters after multivariable adjustment. Conclusions This cross-sectional population-based study revealed independent associations of DHEAS and FT with QUS parameters in men, suggesting a potential influence on male bone metabolism. The predictive role of DHEAS and FT as a marker for osteoporosis in men warrants further investigation in clinical trials and large-scale observational studies. Population-based data of healthy men and women from the general population Sex hormone panel measured by liquid chromatography-mass spectrometry (LC-MS) Associations of dehydroepiandrosterone sulphate and free testosterone with bone ultrasound parameters in men Estrone, androstenedione and SHBG were not associated with bone ultrasound parameters in both sexes.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2017; 14:ijerph14070736.

Abstract
Risk factors for osteoporosis may vary according to different populations. We aimed to investigate the relationship between risk factors of osteoporosis and bone health indices determined via calcaneal quantitative ultrasound (QUS) in a group of Malaysian women aged 50 years or above. A cross-sectional study was performed on 344 Malaysian women recruited from a tertiary medical centre in Kuala Lumpur, Malaysia. They answered a self-administered questionnaire on their social-demographic details, medical history, lifestyle, and physical activity status. Their height was measured using a stadiometer, and their body composition estimated using a bioelectrical impedance device. Their bone health status was determined using a water-based calcaneal QUS device that generated three indices, namely speed of sound (SOS), broadband ultrasound attenuation (BUA), and stiffness index (SI). A T-score was computed from SI values using a reference database from a mainland Chinese population. Women with three or more lifetime pregnancies, who were underweight and not drinking coffee had a significantly lower BUA. Stepwise multiple linear regression showed that SOS was predicted by age alone, BUA and SI by years since menopause, body mass index (BMI), and number of lifetime pregnancies, and T-score by years since menopause and percentage of body fat. As a conclusion, suboptimal bone health in middle-aged and elderly Malaysian women as indicated by QUS is associated with old age, being underweight, having a high body fat percentage, and a high number of lifetime pregnancies. Women having several risk factors should be monitored more closely to protect their bones against accelerated bone loss.

Abstract
OBJECTIVE Abnormal secretion of thyroid hormones, growth hormone, cortisol and androgens influences body composition. We hypothesised that higher cortisol excretion, in combination with higher androgen and IGF-I concentrations, had a synergistic, favourable effect on body mass and bone. DESIGN, PATIENTS AND METHODS This was a cross-sectional study on a population sample of 290 women and 93men. The mean age was 65.4±7.2yearsinwomen and 59.7±10.0yearsinmen. Body composition was assessed with bioimpedance, and skeletal health with calcaneal quantitative ultrasound and fracture rate. The influence of urinary free cortisol (UFC), serum DHEAs (women), testosterone (men), free T4andIGF-I on the outcome was studied with regression analyses adjusted for age and body mass index. RESULTS In women, higher concentrations of UFC, DHEAs, IGF-I and lower free T4, were associated with higher fat-free mass. Only a higher UFC concentration was associated with favourable calcaneal measurements. In men, higher testosterone was associated with higher fat-free mass and lower fat mass. Higher IGF-I concentration, but not UFC, was independently associated with higher fat-free mass in men. Interaction analyses did not reveal any additive effects of hormones on body composition or bone in either sex. In both men and women, only age was associated with osteoporotic fractures. CONCLUSION Serum concentrations of androgens together with IGF-I were positively associated with body composition in both sexes. Urinary cortisol was positively associated with fat-free mass and bone status in women only. Increasing age, but not hormones, was the major determinant of osteoporotic fractures in this population sample.

Abstract
CONTEXT Canagliflozin is a sodium glucose cotransporter 2 inhibitor developed to treat type 2 diabetes mellitus (T2DM). OBJECTIVE Our objective is to describe the effects of canagliflozin on bone mineral density (BMD) and bone biomarkers in patients with T2DM. DESIGN This was a randomized study, consisting of a 26-week, double-blind, placebo-controlled period and a 78-week, double-blind, placebo-controlled extension. SETTING This study was undertaken in 90 centers in 17 countries. PATIENTS Patients were aged 55-80 years (N = 716) and whose T2DM was inadequately controlled on a stable antihyperglycemic regimen. INTERVENTIONS Canagliflozin 100 or 300 mg or placebo were administered once daily. OUTCOME AND MEASURES BMD was assessed using dual-energy x-ray absorptiometry at weeks 26, 52, and 104. Bone strength was assessed using quantitative computed tomography and finite element analysis at week 52. Serum collagen type 1 β-carboxy-telopeptide, osteocalcin, and estradiol were assessed at weeks 26 and 52. RESULTS Canagliflozin doses of 100 and 300 mg were associated with a decrease in total hip BMD over 104 weeks, (placebo-subtracted changes: -0.9% and -1.2%, respectively), but not at other sites measured (femoral neck, lumbar spine, or distal forearm). No meaningful changes in bone strength were observed. At week 52, canagliflozin was associated with an increase in collagen type 1 β-carboxy-telopeptide that was significantly correlated with a reduction in body weight, an increase in osteocalcin, and, in women, a decrease in estradiol. CONCLUSIONS In older patients with T2DM, canagliflozin showed small but significant reductions in total hip BMD and increases in bone formation and resorption biomarkers, due at least in part to weight loss.

Abstract
Obesity is often considered to have a protective effect against osteoporosis. On the other hand, several recent studies suggest that adipose tissue may have detrimental effects on bone quality. We therefore aimed to investigate the associations between body mass index (BMI), waist circumference (WC), visceral adipose tissue (VAT) or abdominal subcutaneous adipose tissue (SAT), and bone stiffness. The study involved 2685 German adults aged 20-79 years, who participated in either the second follow-up of the population-based Study of Health in Pomerania (SHIP-2) or the baseline examination of the SHIP-Trend cohort. VAT and abdominal SAT were quantified by magnetic resonance imaging. Bone stiffness was assessed by quantitative ultrasound (QUS) at the heel (Achilles InSight, GE Healthcare). The individual risk for osteoporotic fractures was determined based on the QUS-derived stiffness index and classified in low, medium, and high risk. Linear regression models, adjusted for sex, age, physical activity, smoking status, risky alcohol consumption, diabetes, and height (in models with VAT or abdominal SAT as exposure), revealed positive associations between BMI, WC, VAT or abdominal SAT, and the QUS variables broadband-ultrasound attenuation or stiffness index. Moreover, BMI was positively associated with speed of sound. Our study shows that all anthropometric measures including BMI and, WC as well as abdominal fat volume are positively associated with bone stiffness in the general population. As potential predictors of bone stiffness, VAT and abdominal SAT are not superior to easily available measures like BMI or WC.

Abstract
The association of vitamin D status with bone mineral density (BMD) and Quantitative Ultrasound measurements (QUS) has been inconsistent in previous studies, probably caused by moderating effects. This study explored (1) the association of vitamin D status with QUS and BMD, and (2) whether these associations were modified by body mass index (BMI), age, gender, or physical activity. Two-independent cohorts of the Longitudinal Aging Study Amsterdam (LASA-I, 1995/1996, aged ≥65; LASA-II, 2008/2009, aged 61-71) and baseline measurement of the B-vitamins for the prevention of osteoporotic fractures (B-PROOF) study (2008-2011, aged 65+) were used. QUS measurements [broadband ultrasound attenuation (BUA) and speed of sound (SOS)] were performed at the calcaneus in all three cohorts (N = 1,235, N = 365, N = 1319); BMD was measured by Dual X-ray absorptiometry (DXA) in B-PROOF (N = 1,162 and 1,192 for specific sites) and LASA-I (N = 492 and 503). The associations of vitamin D status with BUA and BMD were modified by BMI. Only in persons with low-to-normal BMI (<25 kg/m(2)) and serum 25(OH)D <25 nmol/L was associated with lower BUA as compared to the reference group (≥50 nmol/L) in LASA-I and B-PROOF. Furthermore, in LASA-I, these individuals had lower BMD at the hip and lumbar spine. In LASA-II, no associations with BUA were observed. Vitamin D status was not associated with SOS, and these associations were not modified by the effect modifiers tested. The association between vitamin D status and BUA and BMD was modified by BMI in the older-aged cohorts: there was only an association in individuals with BMI <25 kg/m(2).
