A recently developed diagnostic tool, trabecular bone score (TBS), can provide quality of trabecular microarchitecture based on images obtained from dual-energy X-ray absorptiometry (DXA). Since patients receiving glucocorticoid are at a higher risk of developing secondary osteoporosis, assessment of bone microarchitecture may be used to evaluate risk of fragility fractures of osteoporosis. In this pre-post study of female patients, TBS and fracture risk assessment tool (FRAX) adjusted with TBS (T-FRAX) were evaluated along with bone mineral density (BMD) and FRAX. Medical records of patients with (n=30) and without (n=16) glucocorticoid treatment were retrospectively reviewed. All patients had undergone DXA twice within a 12- to 24-month interval. Analysis of covariance was conducted to compare the outcomes between the two groups of patients, adjusting for age and baseline values. Results showed that a significant lower adjusted mean of TBS (p=0.035) and a significant higher adjusted mean of T-FRAX for major osteoporotic fracture (p=0.006) were observed in the glucocorticoid group. Conversely, no significant differences were observed in the adjusted means for BMD and FRAX. These findings suggested that TBS and T-FRAX could be used as an adjunct in the evaluation of risk of fragility fractures in patients receiving glucocorticoid therapy.

We present a case of pulmonary carcinosarcoma. The patient is a 31-year-old man with a history of infectious mononucleosis in whom a right lung mass was found. His age is lower than the mean age at which pulmonary carcinosarcoma is usually reported. Chest CT scan showed a lobulated 29-mm mass in the right upper lung and multiple hypervascular liver nodules. FDG PET/CT showed increased FDG uptake in the right upper lung nodule (SUVmax, 4.1). However, the hepatic radiouptake showed only background activity. The liver nodules were stable at the 1-year follow-up period and were suggestive of hemangiomas.

Background and Objectives: The burden of osteoporosis is projected to increase. Identification and prompt intervention for osteoporotic fractures are important. Adjusting the Fracture Risk Assessment (FRAX®) tool with trabecular bone score (TBS) could improve risk prediction. However, little is known about whether TBS-adjusted FRAX® would change the proportion of individuals qualified for osteoporosis intervention. Therefore, the aim of the present study was to compare the proportions of Taiwanese adults who qualified for intervention, according to the FRAX® and TBS-adjusted FRAX®, with stratification by sex, age group, and glucose regulation status. Materials and Methods: A medical record review on adults 50–90 years who had undergone a general health examination in a regional hospital in Taiwan was conducted. FRAX® and TBS-adjusted FRAX® were calculated. FRAX® cut-points of ≥ 20% for major osteoporotic fracture and ≥3% for hip fracture were adopted to identify individuals qualified for osteoporosis intervention. Individuals were classified as prediabetes and diabetes if their HbA1c was 5.7–6.4% and >6.4%, respectively. Results: A total of 8098 individuals with a mean age of 61.0 years were included. The proportion of men qualified for intervention for hip fracture was significantly lower according to TBS-adjusted FRAX® (17.2%) compared with FRAX® (20.7%) (p < 0.001), with a similar pattern across all three age groups and in those with prediabetes. In contrast, the proportion of women qualified for intervention for major osteoporotic fracture was significantly higher according to TBS-adjusted FRAX® (4.6%) compared with FRAX® (3.7%) (p < 0.001), particularly among those with prediabetes 60–69 years. Conclusions: TBS-adjusted FRAX® led to small but significant changes in the proportions of individuals qualified for intervention in specific age groups and glucose regulation status.

Purpose. To examine the association between fracture risk assessment tool (FRAX) scores and coronary artery calcification (CAC) score in adults. Methods. The medical records of 81 adults who underwent both coronary computed tomography and bone mineral density (BMD) studies in a package during their health exams were reviewed at a regional hospital in Southern Taiwan. Data collected included health history, anthropomorphic characteristics, clinical laboratory results, and BMD. Fracture risk was determined using FRAX. Univariate and multivariate linear regression analysis were used to assess the association between CAC score and 10-year probability of hip fracture (HF) and major osteoporotic fracture (MOF) determined by FRAX. Results. The mean age of the patients was 55.8 years, and 63.0% were male. Univariate linear regression analysis showed that increases in MOF and HF risks, as measured by FRAX, were significantly and positively associated with CAC score. Multiple linear regression analysis adjusting for potential confounders showed that CAC score remained significantly associated with four FRAX indicators, including right MOF (r=0.45, P<0.001), left MOF (r=0.31, P=0.021), right HF (r=0.38, P=0.001), and left HF (r=0.23, P=0.049). Conclusions. Increased risks of MOF and HF as determined by FRAX were significantly and independently associated with CAC score.

Purpose. This study is aimed at determining whether bone mineral density (BMD) values are related to atherogenic indexes (AIs) and could predict the risk of cardiovascular disease (CVD) in southern Taiwanese adults. Methods. Medical records of 3249 adults who underwent health examinations between June 2014 and February 2018 at a regional hospital in southern Taiwan were reviewed. Data collected included health history, anthropomorphic characteristics, exercise habits, diets (vegetarian or nonvegetarian), clinical laboratory results (lipid profile, systemic blood pressure (SBP), glucose level, creatinine (Cre) level, and hemoglobin (Hb) level), and bone mineral density (BMD), which were used to identify the associations of these parameters, especially BMD, with lipid profile and calculated AIs through simple and multiple linear regressions. Results. The mean age of the patients was 58.0 years, and 71.4% were male. Body mass index (BMI), SBP, glucose level, Cre level, Hb level, and all BMD values were positively correlated with triglyceride (TG) level and AIs and were negatively correlated with high-density lipoprotein cholesterol (HDL-C) level. The significant positive correlations of BMD at all the measured sites with AIs remained after adjusting for age, sex, SBP, glucose level, Cre level, Hb level, smoking, exercise habits, and vegetarian state. The expanded adjusting model for TG/HDL-C remained significant at all the BMD measured sites in nonobese men, at bilateral femoral neck and total hips in nonobese women, and at the bilateral total hips in obese women. Conclusions. AIs are predictive markers for CVD, and BMD values are predictors of AIs, especially the novel AI, i.e., TG/HDL-C ratio, in nonobese adult men and women after dividing the patients into subgroups to eliminate the effect of BMI as a confounding factor. Thus, BMD values could predict AIs of CVD, especially in nonobese adults.

The effect of a vegetarian diet on bone health remains controversial. This retrospective medical record review compared changes in bone mineral density (BMD) and trabecular bone score (TBS) between vegetarian and non-vegetarian middle-aged and older women who underwent two general health examinations (T1 and T2) that were approximately three years apart. Generalized estimating equations were used to compare the change in lumbar spine and bilateral hip BMD and TBS over time. At T1, the mean age of the patients was 56.6 years (standard deviation 9.7 years) and the mean interval between T1 and T2 was 2.7 years. For women aged 40–55 years, compared with non-vegetarians, vegetarians were significantly associated with a larger reduction in lumbar spine BMD (p < 0.001) and left hip femoral neck BMD (p = 0.015) over the three-year interval. On the contrary, changes in BMD were not significant at any site in women aged ≥ 56 years. Moreover, the changes in BMD and TBS over the three-year interval did not significantly differ between vegetarian and non-vegetarian women aged 65–90 years. In conclusion, for women aged 40–55 years, vegetarian diets reduced bone quantity, as measured by BMD, but not bone quality, as measured by TBS.
