OBJECTIVES: One of the important risk factors of falling is decreased muscle mass and muscle strength. Recently, there has been an increasing concern on the role of vitamin D in muscle strength and physical activity. Aim of our study is to examine the relationships between vitamin D status and muscle mass and muscle strength in middle-aged healthy adults. METHODS: Subjects were 40 healthy volunteers aged 42.0 ± 10.6 years old. Evaluation was made for serum vitamin D₃ metabolites including 25-hydroxyvitamin D₃ [25(OH)D₃] and 24,25-dihydroxyvitamin D₃ [24,25(OH)₂D₃] concentrations, lower limb muscle strength, and dietary intake by food frequency questionnaire. Body composition was measured by dual-energy X-ray absorptiometry (DXA), and appendicular skeletal mass index (ASMI) was calculated as skeletal muscle mass/squared height. RESULTS: 70% of the subjects had vitamin D insufficiency/deficiency (serum total 25(OH)D < 20 ng/mL), and female subjects had significantly lower serum total 25(OH)D level compared with males. Vitamin D insufficiency/deficiency group had significantly higher body fat, lower SMI and muscle strength, probably reflecting higher percentage of female subjects. Serum vitamin D₃ metabolites levels were significantly correlated with whole and site-specific ASMI, and lower limb muscle strength, except for the correlation between serum 24,25(OH)₂D₃ concentration and lower limb muscle strength. In addition, serum 25(OH)D₃ level was a positive significant predictor for both ASMI and lower limb muscle strength, while serum 24,25(OH)₂D₃ level was not their significant predictor. CONCLUSIONS: Serum 25(OH)D₃ level was significantly correlated with both skeletal muscle mass and lower limb muscle strength.

OBJECTIVES: This study aimed to investigate the correlation between bone mineral density (BMD) and the turnover rate [√(MoMf²+ MoMr²), multiple of median formation (MoMf) was calculated as bone-specific alkaline phosphatase (BAP) value/18.6 and multiple of median resorption (MoMr) as tartrate-resistant acid phosphatase 5b (TRACP-5b) value/463] and the balance (MoMf/MoMr) and to compare differences in therapeutic effects evoked by differences in previous treatments. METHODS: In 51 osteoporotic women treated with bisphosphonates (BPs) or selective estrogen receptor modulators (SERMs), BMD was measured at 0, 24, and 48 weeks after denosumab administration. The values of BAP and TRACP-5b were measured at 0, 4, 12, 24, 36, and 48 weeks. RESULTS: The turnover rate decreased at week 4 and decreased further at week 12. The balance indicated a relative predominantly formative state at week 4. This balance became higher in the SERM group than in the BP group at week 4. A correlation was observed between the rate of BMD change and turnover rate at weeks 0 and 4. CONCLUSIONS: It is necessary to evaluate the turnover rate and balance to determine the therapeutic effect of denosumab, which induces dissociation between the trends in the bone turnover markers. Turnover rate and balance during the early stages of denosumab treatment may be predictive factors of BMD. When switching from bone resorption inhibitors to denosumab, it was necessary to consider the beginning values that were affected by the previous treatment. The state of relative anabolism is greater at 4 weeks when the previous treatment involved SERMs rather than BPs.

OBJECTIVES: This is an open labeled and retrospective cohort study which compared the effectiveness and safety of ibandronate (IBN) and minodronate (MIN) combined with eldecalcitol (ELD) in primary osteoporosis of women. METHODS: One hundred and forty-eight primary osteoporotic women were classified into 3 groups; 1) intravenous IBN combined with oral ELD (IBN + ELD group, N = 50; 81.8 ± 6.2 years), 2) oral MIN combined with oral ELD (MIN + ELD group, N = 50; 77.2 ± 6.9 years) and 3) oral ELD alone (ELD group, N = 48; 75.0 ± 8.3 years). For statistical analysis, L-BMD, H-BMD, serum corrected Ca, serum iP, intact-PTH, TRACP-5b, BAP, serum Hcy, eGFR and urine Ca/Cr ratio were measured until 12 months after the start of therapy. RESULTS: L-BMD values increased significantly in both IBN + ELD and MIN + ELD group, however, H-BMD increased significantly in the IBN + ELD group only. TRACP-5b values decreased rapidly during the first 6 months in both IBN + ELD and MIN + ELD group. However, BAP value in the IBN + ELD group decreased more gradually compared with that in the MIN + ELD group. Both serum Ca value and urine Ca/Cr ratio tended to increase, and the eGFR value decreased significantly in each group. CONCLUSIONS: IBN combined with ELD administration can act more effectively to increase BMD compared with MIN combined with ELD administration. Differences of decreasing rate in TRACP-5b and BAP value may lead to differences of increased rate of BMD in the IBN + ELD and MIN + ELD group. Because many cases of osteoporosis are elderly persons associated with chronic kidney disease, monitoring of kidney function and concentration of Ca in blood and urine is essential.

OBJECTIVES: The aim of this study was to investigate associations between skeletal muscle mass and bone mineral density according to gender and skeletal sites. METHODS: Using the data from Korean National Health and Nutrition Examination Survey (KNHANES IV) 2009, a total of 711 males and 847 females over 65 years of age were evaluated. Bone mineral density (BMD) and body composition were assessed using dual-energy X-ray absorptiometry. RESULTS: Relative appendicular skeletal muscle (RASM) was positively related with the femur BMD with a stronger relationship in males (r = 0.207, p < 0.001) than in females (r = 0.095, p < 0.05). However, lumbar spine BMDs in both males and females did not show any significant associations with the RASM value. In the logistic regression for osteoporosis expressed as a decrease of risk per increase of RASM by 1 standard deviation (SD) of the same sex healthy reference group, the age- and BMI-adjusted odds ratio (OR) for osteoporosis was 0.42 (95% CI 0.12–0.76) in the femur neck and 0.24 (95% CI 0.07–0.76) in the total hip for males. Among females, the age- and BMI-adjusted OR for osteoporosis was 0.65 (95% CI 0.33–1.00), which showed importance only in the total hip. CONCLUSIONS: Higher RASM was significantly associated with lower risk for osteoporosis and the areas at the femur neck and total hip appeared to more likely be affected positively by muscle. Moreover, because males showed faster muscle loss with aging than females, the bones of males may be more prone to favorable effects of muscle.

Osteoporosis prevention and osteoporosis exercise in community-based public health programs.
Osteoporosis and Sarcopenia.2017;3(1):18-31. doi:10.1016/j.afos.2016.11.004
Osteoporosis is a serious public health concern worldwide, and community-based public health programs that increase osteoporosis preventive behaviors are ideal to combat this major public health issue. A review of community-based public health programs for osteoporosis prevention show that programs vary in numerous ways and have mixed results in increasing osteoporosis preventive behaviors, although most programs have had success in significantly increasing calcium intake, only a few programs have had success in significantly increasing weightbearing exercise. Regarding calcium intake, all community-based public health programs that implemented: 1) at least one theoretical behavior change model, such as the health belief model, or 2) bone mineral density (BMD) testing for osteoporosis screening, have shown success in significantly increasing calcium intake. As community-based public health programs for osteoporosis prevention have shown limited success in increasing weight-bearing exercise, an additional review of community-based public health programs incorporating osteoporosis exercise showed that they have high compliance rates to increase weight-bearing exercise, but require high-intensity weight-bearing exercise of 80–85% 1-repetition maximum to significantly increase BMD to prevent osteoporosis. In the prevention of osteoporosis, for community-based public health programs to be most effective, they should implement theoretical behavior change models and/or BMD testing for osteoporosis screening, along with high-intensity resistance training. Recommendations for future research to further study effective community-based public health programs are also provided.

Determination of normative reference for the definition of sarcopenia among Filipinos.
Osteoporosis and Sarcopenia.2016;2(3):186-190. doi:10.1016/j.afos.2016.07.004
BACKGROUND: At present, there is no normative value that can be used in the definition of sarcopenia in the Philippines. OBJECTIVE: We identified the reference cut-off values for: 1) muscle mass using bioimpedance analysis; 2) grip strength; 3) usual gait speed; 4) timed get-up-and-go; and 5) short physical performance battery in the Philippines in order to adapt the European Working Group on Sarcopenia in Older People (EWGSOP) criteria for the definition of sarcopenia. METHODS: Two hundred seventy six (135 males and 141 females) healthy Filipino adults, between 20 and 40 years, were included in this cross sectional study. A Fresenius Body Composition Monitor was used to measure lean tissue mass (LTM) and lean tissue index (LTI). A dynamometer was used to measure grip strength. Usual gait speed, timed get-up-and-go, and short physical performance battery were also determined. RESULT: The normative references for males and females, respectively, for LTI were 17.10 + 2.337 kg/m² and 12.63 + 2.119 kg/m²; for usual gait speed were 1.06 + 0.251 m/sec and 0.930 + 0.144 m/sec; and for grip strength were 39.76 + 7.567 kg and 26.68 + 5.243 kg. The sarcopenia cut-points for the males and females, respectively, for LTI were <12.50 kg/m² and <8.33 kg/m²; for usual gait speed were <0.55 m/sec and <0.65 m/sec; and for grip strength were <24.54 kg and <16.10 kg. CONCLUSION: This study presents cut-points for the determination of sarcopenia at-risk population among Filipinos.

The purpose of this study was to investigate the causes of failure to return to the pre-fracture place of residence at hospital discharge following an operation for a hip fracture and to continue medical treatment for osteoporosis. Herein, we discuss methods for improving discharge protocols for these patients. We examined patients who sustained osteoporotic fractures and were operated on for a hip fracture between 2001 and 2003 (83 males and 386 females; 81.2 ± 9.0 years old) and between 2011 and 2013 (121 males and 462 females; 83.1 ± 9.3 years old). In a follow-up study, we examined patients who moved into our related rehabilitation institution over a 3-year period, from 2011 to 2013. The incidence of hip fractures had increased from 2001-2003 to 2011-2013 in both genders, and it tended to increase in patients greater than 80 years of age in male and 90 years of age in female. The most common destination residence after discharge from the rehabilitation institution was the pre-fracture place of residence. The Barthel Index at discharge from the rehabilitation institution was significantly lager in patients who returned to the pre-fracture place of residence compared to those who returned to nursing home and our hospital. These results suggest improved mobility and ADL level of patients enable them to return to the pre-fracture place of residence. We propose the construction of a feedback system that aids in a medical pass to increase the ambulant consultation rate for orthopedics and prevent fragile fractures.

OBJECTIVE: The purpose of this study was to evaluate changes in bone quantity based on bone mineral density (BMD) and bone quality based on trabecular bone score (TBS) in Graves' disease patients after anti-thyroid therapy. RESEARCH DESIGN AND METHOD: This retrospective study included premenopausal female and male patients with Graves' disease who received BMD measurement more than two times during treatment. BMD and thyroid function tests with free thyroxine (FT4), total triiodothyronine (T3), thyroid stimulating hormone (TSH), and TSH receptor antibody (TRAb) levels were collected two times during follow-up. TBS was calculated using TBS insight® software (version 2.1) from dual-energy X-ray absorptiometry images. RESULTS: Thirty Graves' disease patients (17 males, 56%; 13 premenopausal females, 44%) with a mean age of 35.3 ± 9.9 years were included. The mean follow-up period was 20.7 ± 8.5 months. The median levels of FT4, TSH and TRAb improved at follow-up [2.55 ng/dL (Interquartile range (IQR) 2.07-3.78) to 1.28 ng/dL (IQR 1.23-1.39), 0.015 mIU/L (IQR 0.01-0.04) to 0.89 mIU/L (IQR 0.35-1.55), 17.0 IU/L (IQR 5.0-40.3) to 5.0 IU/L (5.0-6.0), respectively; p < 0.001]. Median BMD (lumbar spine) values also improved from 1.118 g/cm² (IQR 1.000-1.119) to 1.167 g/cm² (IQR 1.050-1.219) ( p = 0.001) at follow-up. TBS increased from 1.377 (IQR 1.299-1.422) to 1.390 (IQR 1.327-1.430) after treatment ( p = 0.038). CONCLUSIONS: Both bone quality and density improved after anti-thyroid treatment in premenopausal female and male Graves' disease patients.
