Abstract
BACKGROUND Vertebral compression fractures (VCFs) in older adults cause considerable health and socioeconomic burdens due to worsening ability to perform activities of daily living. The long-term effects of VCFs on patient outcomes, particularly prolonged analgesic use and functional decline, remain unknown. The aims of this study were to examine long-term clinical outcomes and to determine the risk factors for persistent pain and functional disability after VCFs. METHODS This retrospective cohort study evaluated mortality, duration of analgesic use, and changes in care requirements in older adults with VCFs using claims data from a suburban prefecture in the Greater Tokyo Area. Patients were included if they were ≥65 years of age and had been diagnosed with a VCF between June 2014 and February 2019, as determined on the basis of International Classification of Diseases, Tenth Revision (ICD-10) codes; we also used claims data that could determine whether the patients underwent imaging examinations. Patients who discontinued outpatient visits within 1 month after the VCF diagnosis were excluded. RESULTS We included 18,392 patients with VCFs and a mean age of 80 years. Seventy-six percent of patients were women, and the median follow-up period was 670 days. At the index VCF diagnosis, 3,631 patients (19.7%) were care-dependent. Overall, 968 patients (5.3%) died within 1 year. Among the 8,375 patients who received analgesics, 22% required analgesics for >4 months. Factors associated with prolonged analgesic use for >1 year were female sex (odds ratio [OR], 1.39 [95% confidence interval (CI), 1.16 to 1.65]) and VCFs in the thoracolumbar region (OR, 1.95 [95% CI, 1.50 to 2.55]) or lumbar region (OR, 1.59 [95% CI, 1.23 to 2.04]) (the reference was the thoracic region). The care needs of 1,510 patients (8.2%) increased within 1 year. Patients with a preexisting care dependency had a 10 times higher risk of increased care need (30.2% [1,060 of 3,509]) than those who had been independent at the time of the index diagnosis (3.0% [450 of 14,761]) (p < 0.001). CONCLUSIONS Individuals with preexisting care dependency were more likely to experience functional decline following VCFs than those who were independent, which underscores the need for intensive and appropriate allocation of health-care resources to care-dependent patients.

Abstract
[Purpose] This study aimed to investigate the effect of the location of electrode attachment in transcutaneous electrical nerve stimulation on pain relief in patients with lumbar vertebral body fractures. [Participants and Methods] This study included 59 patients with lumbar vertebral body fractures, who were randomly assigned to receive transcutaneous electrical nerve stimulation to the lumbar region, lower limbs, or upper limbs, or no treatment, over a 4-week period. Pain, activities of daily living, and pain catastrophizing were assessed. [Results] Compared with the control group, transcutaneous electrical nerve stimulation to the lumbar region or lower limbs significantly reduced pain levels in the first 2 weeks. Although, activities of daily living and pain catastrophizing improved over time, no significant differences were observed between the groups. [Conclusion] Transcutaneous electrical nerve stimulation provides pain relief to patients during the early stages of lumbar vertebral body fractures. However, it had no effect on the activities of daily living, pain catastrophizing, or long-term pain-relief. For lumbar vertebral body fracture pain relief, transcutaneous electrical nerve stimulation electrodes should be attached to the lumbar region or lower limbs.

[PMID: 37905358 DOI: 10.1002/pmrj.13092] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2022] [Revised: 10/07/2023] [Accepted: 10/16/2023] [Indexed: 11/02/2023]
Abstract
BACKGROUND Vertebral compression fractures, which are commonly associated with older age and osteoporotic fractures, have an increased risk of re-fracture. Therefore, improving balance is important to prevent falls. The minimal important change (MIC) has been recommended for interpreting clinically meaningful changes in rating scales. The MIC of the Berg Balance Scale (BBS) for use in older women with vertebral compression fractures has not been established. OBJECTIVE To identify the MIC of the BBS that can be used in older women with vertebral compression fractures using predictive modeling methods and the receiver-operating characteristic (ROC)-based method. DESIGN A retrospective longitudinal multicenter study. PATIENTS Sixty older women (mean age ± standard deviation: 84.1 ± 7.0 years) with vertebral compression fractures who were unable to ambulate independently on a level surface. METHODS A change of one point in the Functional Ambulation Category (FAC) was used as an anchor to calculate the MIC of the BBS based on the change between admission and discharge. We calculated the MIC for the women whose FAC score improved by ≥1 point. We used three anchor-based methods to examine the MIC: the ROC-based method (MICROC), the predictive modeling method (MICpred), and the MICpred-based method adjusted by the rate of improvement and reliability of transition (MICadj). RESULTS Thirty-nine women comprised the "important change" group based on their FAC score improvement. In this group, the MICROC (95% confidence interval [CI]) value of the BBS was 10.0 points (5.5-15.5), with an area under the curve of 0.71. The MICpred (95% CI) value was 9.7 (8.1-11.0), and the MICadj (95% CI) was 7.0 (5.5-8.5) points. CONCLUSION For women with vertebral compression fractures who are unable to ambulate independently, a 7.0-point improvement in the BBS score may be a useful indicator for reducing the amount of assistance required for walking.

Osteoporos Int 2024; 35:795-804. [PMID: 38261013 DOI: 10.1007/s00198-024-07025-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/06/2023] [Accepted: 01/13/2024] [Indexed: 01/24/2024]
Abstract
Teriparatide and denosumab, anti-osteoporosis medications with different mechanisms, have been widely used in the patients with osteoporotic vertebral fracture (OVF) considered as advanced osteoporosis. Teriparatide has been shown to enhance bone formation and fracture healing in OVF, but there are still no sufficient evidences discussing about the role of denosumab in newly developed OVF. In this study, we found the similar radiological deformation and functional outcomes of conservative treatment with teriparatide and denosumab in thoracolumbar (TL) OVF, and teriparatide showed a more frequent incidence of fracture union with paravertebral bone bridge formation compared to denosumab. INTRODUCTION Teriparatide and denosumab have been widely used to treat advanced osteoporosis and prevent subsequent fractures in patients with OVCF. Unlike teriparatide, which is considered to be effective in fracture healing, there is still no clear role and evidence for the effect of denosumab in acute OVCF. This study compared the radiological and functional outcomes of conservative treatment with teriparatide and denosumab in TL-OVF. METHODS This retrospective study enrolled 78 women with mean age of 74.69 ± 7.66 (60-92) years diagnosed as a TL-OVF with no neurological deficits. All patients were treated conservatively with teriparatide (34 of group T, once-daily 20 μg) or denosumab (44 of group D, once-6 months 60 mg) for 6 months. We evaluated the radiological deformation (kyphotic angle, segmental vertebral kyphotic angle, and compression ratio) and the incidence of fracture union with paravertebral bone bridge formation (FUPB) and functional outcomes using the visual analog scale (VAS) and Oswestry Disability Index (ODI) at 0, 3, and 6 months. RESULTS In the radiological deformation and functional outcomes, there were no significant differences at 0, 3, and 6 months between the two groups (P > 0.05). However, the incidence of FUPB at 6 months was higher in group T (20/34, 58.8%) compared to group D (11/44, 25.0%) (P = 0.004), and teriparatide was the most statistically significant factor for achieving FUPB (OR 4.486, P = 0.012) in multivariable logistic analysis. CONCLUSIONS Teriparatide and denosumab, despite of their different pharmacological mechanisms, showed similar radiological deformation and functional outcomes in the conservative treatment of TL-OVF. However, teriparatide showed a significantly higher incidence of fracture union with paravertebral bone bridge formation.

Abstract
BACKGROUND Early assessment of the risk of nonunion in osteoporotic vertebral compression fracture (OVCF) is beneficial to early clinical decision making. However, a comprehensive understanding of the risk factors for OVCF nonunion is lacking. METHODS We conducted a case-control study to investigate risk factors for OVCF nonunion. Patients who underwent surgery for nonunited OVCFs between January 2011 and December 2021 were eligible for inclusion as cases. Patients with successful OVCF healing confirmed by MRI over the same period were identified as controls. Patient demographics, comorbidities, and fasting blood test data were extracted for analysis. RESULTS A total of 201 patients with nonunited OVCFs and 1044 controls were included to evaluate the risk factors for nonunited OVCFs. There were statistically significant differences in sex, age, number of patients with hypertension, number of patients on bed rest after OVCF and T-score of BMD between the two groups. Logistic regression showed that female patients had a higher risk of OVCF nonunion than male patients and that smoking, drinking, diabetes, and hypertension were risk factors for nonunion of OVCFs, while bed rest and spinal support were protective factors against nonunion of OVCFs. We also found that age, BMD, FBG, and β-CTX were positively correlated with nonunited OVCFs, and that HGB and 1,25-(OH)2VitD3 level were negatively correlated with nonunited OVCFs. CONCLUSION Smoking, drinking, diabetes and hypertension were risk factors for nonunion of OVCFs, while bed rest and spinal support were protective factors against nonunion of OVCFs. Age, BMD, FBG and β-CTX were positively correlated with nonunited OVCFs, while HGB and 1,25-(OH)2VitD3 level were negatively correlated with nonunited OVCFs. Based on the results of our study, we suggest that bed rest or spinal support for at least 3 consecutive weeks is necessary to reduce the risk of OVCFs nonunion.

Abstract
BACKGROUND Lower mortality has been demonstrated when vertebral compression fractures (VCFs) are treated surgically (vertebral augmentation) vs. conservatively. AIMS To analyze the overall survival in patients over 65 who suffer a VCF, to review the principal causes of death, and to detect which factors are associated with a greater risk of mortality. METHODS Patients over 65 years old diagnosed with acute, non-pathologic thoracic or lumbar VCF, treated consecutively from January 2017 to December 2020, were retrospectively selected. Those patients with follow-ups under 2 years or who required arthrodesis were excluded. Overall survival was estimated by the Kaplan-Meier method. Differences in survival were tested through the log-rank test. Multivariable Cox regression was used to assess the association of covariates and time to death. RESULTS A total of 492 cases were included. Overall mortality was 36.2%. Survival rate at 1-, 12-, 24-, 48-, and 60-month follow-up was 97.4%, 86.6%, 78.0%, 64.4%, and 59.4%, respectively. Infection was the leading cause of death. The independent factors associated with a higher mortality risk were age, male, oncologic history, non-traumatic mechanism, and comorbidity during hospitalization. No statistical difference was found when comparing the two survival curves by treatment (vertebral augmentation vs. conservative) over time. CONCLUSION Overall mortality rate was 36.2% after a median follow-up of 50.5 months (95% CI 48.2; 54.2). Age, male sex, history of oncological disease, non-traumatic mechanism of the fracture, and any comorbidity during hospitalization were identified as variables independently associated with a higher risk of mortality following a VCF in the elderly.

Abstract
This systematic review and meta-analysis examined the association between race and ethnicity and fracture risk in the United States. We identified relevant studies by searching PubMed and EMBASE for studies published from the databases' inception date to December 23, 2022. Only observational studies conducted in the US population that reported the effect size of racial-ethnic minority groups versus white people were included. Two investigators independently conducted literature searches, study selection, risk of bias assessment, and data abstraction; discrepancies were resolved by consensus or consultation of a third investigator. Twenty-five studies met the inclusion criteria, and the random-effects model was used to calculate the pooled effect size due to heterogeneity between the studies. Using white people as the reference group, we found that people of other races and ethnic groups had a significantly lower fracture risk. In Black people, the pooled relative risk (RR) was 0.46 (95% confidence interval (CI), 0.43-0.48, p < 0.0001). In Hispanics, the pooled RR was 0.66 (95% CI, 0.55-0.79, p < 0.0001). In Asian Americans, the pooled RR was 0.55 (95% CI, 0.45-0.66, p < 0.0001). In American Indians, the pooled RR was 0.80 (95% CI, 0.41-1.58, p = 0.3436). Subgroup analysis by sex in Black people revealed the strength of association was greater in men (RR = 0.57, 95% CI = 0.51-0.63, p < 0.0001) than in women (RR = 0.43, 95% CI = 0.39-0.47, p < 0.0001). Our findings suggest that people of other races and ethnic groups have a lower fracture risk than white people.

Abstract
Osteoporotic vertebral fractures are recognized as a serious problem in the aging society. In this study, we found that the cumulated ambulation score predicts returning home in patients with osteoporotic vertebral fractures. The cumulated ambulation score is an important piece of information in determining the destination of patients with osteoporotic vertebral fractures. PURPOSE Osteoporotic vertebral fractures are a serious problem affecting the health status of the elderly, and if they require inpatient treatment, they may have difficulty deciding where to discharge. The study's purpose is to investigate whether the cumulated ambulation scores predict returning home for hospitalized osteoporotic vertebral fractures patients. METHODS The subjects were 120 osteoporotic vertebral fractures patients aged 65 years or older who were admitted to our hospital between April 2015 and March 2022. The cumulated ambulation scores for all subjects were measured in the 3-days right after admission. A multivariable analysis was performed with the dependent variable as whether the patient returned home and the independent variable as the cumulated ambulation score. Three models were created from the measured cumulated ambulation score, and each model was analyzed as an independent variable (model 1; score on the 1st day, model 2; total score on the 2-days, model 3; total score on the 3-days). RESULTS The length of hospitalization for the osteoporotic vertebral fracture's patients were 11.8 ± 5.3 days, and 80 (66.7%) returned home. Multivariable analysis showed that cumulated ambulation score was a predictor of returning home (model 1, odds ratio: 3.151, 95% confidence interval: 2.074-5.203; model 2, odds ratio: 2.234, 95% confidence interval: 1.685-3.187; model 3, odds ratio: 1.929, 95% confidence interval: 1.535-2.599). CONCLUSION The cumulated ambulation score of patients with osteoporotic vertebral fractures right after admission is a factor that affected returning home and is useful in determining where patients are discharged.

Abstract
In this population-based, cross-sectional study, we investigated vertebral fracture (VF) prevalence among Chinese postmenopausal women. We found 14.7% of population had VFs, which increased with age. Age ≥ 65 years, hip fracture, and densitometric osteoporosis were significantly associated with VFs. The prevalence of osteoporosis was remarkably high. PURPOSE To investigate VF prevalence among Chinese postmenopausal women in this population-based, randomized-sampling, cross-sectional study. METHODS The investigator obtained lists of women from communities. Randomization was performed using SAS programming based on age group in each region. Postmenopausal women aged ≥ 50 years in the urban community were included. The investigator interviewed subjects to collect self-reported data and measured BMD. Spine radiographs were adjudicated by Genant's semi-quantitative method. VFs were defined as fractures of at least one vertebra classified by Genant's score 1-3 and were analyzed using descriptive statistics. RESULTS A total of 31,205 women listed for randomized sampling from 10 Tier-3 hospitals at 5 regions. Of 2634 women in the full analysis set, 14.7% (388/2634, 95% CI: 13.4, 17.1) had prevalent VFs. VF prevalence increased with age (Cochran-Armitage test p < 0.0001) and was significantly higher in women aged ≥ 65. VF prevalence did not differ between North (14.4%, 95% CI: 12.5, 16.4) and South China (15.1%, 95% CI: 13.3, 17.1). In women with no prior VFs, prevalent VFs were 12.4% (95% CI: 11.2, 13.7). Age ≥ 65 years (OR: 2.57, 95% CI: 1.91, 3.48), hip fracture (OR: 2.28, 95% CI: 1.09, 4.76), and densitometric osteoporosis (OR: 2.52, 95% CI: 1.96, 3.22) were significantly associated with prevalent VFs. Prevalence of osteoporosis was 32.9% measured by BMD and 40.8% using NOF/IOF clinical diagnosis criteria. CONCLUSION VFs are prevalent among Chinese postmenopausal women who were ≥ 50 years and community-dwelled. Osteoporosis prevalence is remarkable when fragile fractures were part of clinical diagnosis.

Percutaneous kyphoplasty combined with zoledronic acid for the treatment of primary osteoporotic vertebral compression fracture: a prospective, multicenter study. Arch Orthop Trauma Surg 2022:10.1007/s00402-022-04557-4. [PMID: 35933563 DOI: 10.1007/s00402-022-04557-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/18/2022] [Accepted: 07/16/2022] [Indexed: 11/02/2022]
Abstract
INTRODUCTION To explore the therapeutic efficacy of percutaneous kyphoplasty (PKP) combined with zoledronic acid (ZOL) in postmenopausal women and adult men with osteoporotic vertebral compression fracture (OVCF). MATERIALS AND METHODS A total of 238 patients with OVCF were randomly assigned to the control or ZOL group: 119 patients were treated with only PKP (control group), and 119 were treated with ZOL infusion after PKP (ZOL group). Clinical, radiological and laboratory indices were evaluated at follow-up. RESULTS The visual analog scale (VAS) score and Oswestry Disability Index (ODI) were significantly higher in both groups post-treatment than at baseline (all p < 0.01). The bone mineral density (BMD) of the proximal femoral neck and height of the injured vertebra were significantly increased after treatment compared with before treatment, and the Cobb angle of the injured vertebra was significantly decreased in both groups (all p < 0.01). However, the bone metabolism indices (type I procollagen amino-terminal peptide (PINP), beta type I collagen carboxy-terminal peptide (β-CTX), and osteocalcin in the N-terminal molecular fragment (NMID)) were significantly lower post-treatment than at baseline in only the ZOL group (all p < 0.01). The VAS score, ODI, BMD, PINP level, β-CTX level, NMID level, vertebral height and Cobb angle of the injured vertebra were significantly higher in the ZOL group than in the control group (all p < 0.01). There were no significant differences in the postoperative bone cement leakage rate between the two groups. At follow-up, new OVCFs were experienced by 16 patients in the control group and 2 patients in the ZOL group (p < 0.01). CONCLUSION The therapeutic efficacy of PKP combined with ZOL for primary OVCF is clinically beneficial and warrants further study.

[PMID: 34906740 DOI: 10.1016/j.spinee.2021.12.007] [Citation(s) in RCA: 34] [Impact Index Per Article: 17.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/23/2021] [Revised: 12/07/2021] [Accepted: 12/07/2021] [Indexed: 02/03/2023]
Abstract
BACKGROUND CONTEXT In the context of the population growing and aging worldwide, the epidemiology, and burden of vertebral fracture have not been comprehensively analyzed. PURPOSE To delineate the global number and rate of incidence, prevalence and burden of vertebral fracture in 2019, and the temporal trends from 1990 to 2019 by location, age, sex, and the socio-demographic index (SDI). STUDY DESIGN/SETTING A cross-sectional study using data from the Global Burden of Disease Study 2019 (GBD study 2019). PATIENT SAMPLE Patients with vertebral fracture documented in medical records or registrations and included in the GBD study 2019 from different countries worldwide. OUTCOME MEASURES Age standardized incidence rate (ASIR), age standardized prevalence rate (ASPR), and age standardized years lived with disability (YLDs). METHODS The GBD study 2019 was used to obtain data for this analysis. The incidence, prevalence and disability were analyzed by location, year, sex, age, and SDI. DisMod-MR 2.1, a Bayesian meta-regression tool, was used to produce the estimates for each value after adjustment for age, sex, and other variables. Estimated annual percentage change (EAPC) was calculated to represent the temporal trends from 1990 to 2019. Spearman's rank order correlation was used to determine the correlation between SDI and the incidence and burden of vertebral fracture. This work was supported by the Key Research and Development Program of Hubei Province of China (No. 2020BCB049), and no conflicts of interest-associated biases existed in this study. RESULTS Globally, there were 8.6 million (95% uncertainty interval [UI], 6,6-11,3 million) incident cases, 5.3 million (95% UI, 4.6-6.2 million) prevalent cases, and 0.55 million (95% UI, 0.37-0.77 million) YLDs of vertebral fracture. Compared with 1990, the number of incident cases and YLDs in 2019 increased by 38% (95% UI, 23%-48%) and 75% (95% UI, 65%-85%), respectively, while the ASIR (EAPC, -0.28; 95% CI, -0.41 to -0.14), ASPR (EAPC, -0.12; 95% CI, -0.22 to -0.02) and age standardized YLD rate (ASYR) (EAPC, -0.13; 95% CI, -0.23 to -0.04) decreased during this period. High ASIR, ASPR and ASYR were commonly seen in high-SDI countries, such as high-income North America, Australia, Central and Eastern Europe. In the country level, positive correlations were observed between SDI and ASIR (rho, 0.596; p<.001) and ASYR (rho, 0.413; p<.001). Males had higher ASIR and ASYR worldwide in each year from 1990 to 2019. However, the incidence, and YLD rates in females surpassed that in males after 65 years of age. Increasing trends were observed for both incidence and YLD rates with age. Falls were the leading cause for vertebral fracture across all ages. CONCLUSIONS The past thirty years have seen increasing numbers but decreasing rates of global incidence, prevalence, and disability of vertebral fractures, resulting from the growing population worldwide. With population aging, efforts are still in urgent need to address vertebral fracture related health outcomes.

Abstract
To identify patients at a high risk for primary and secondary osteoporotic fractures using fracture risk assessments performed using the current method and the proposed method, in an acute care hospital and to identify departments where high-risk patients are admitted. This retrospective study included patients aged 40-90 years who were hospitalized at Fujita Health University Hospital. We collated the clinical data and prescriptions of all study participants. We also gathered data pertaining to risk factors according to Fracture Risk Assessment Tool (FRAX). Of the 1,595 patients, the mean number of major osteoporotic fracture risk predicted using FRAX was 11.73%. The department of rheumatology showed the highest fracture risk (18.55 ± 16.81) and had the highest number of patients on medications that resulted in reduced bone mineral density (1.07 ± 0.98 medication). Based on the FRAX, the proportion of patients in the high-risk group in this department was significantly higher compared with those in the remaining departments with respect to glucocorticoid administration, rheumatoid arthritis, and secondary osteoporosis. However, the departments included in the high-risk group were not necessarily the same as the departments included in the top group, based on the administered medications. FRAX score is calculated based on various risk factors; however, only glucocorticoid corresponds to medications. We should focus on medication prescription patterns in addition to FRAX to improve fracture risk assessment in hospital-wide surveillance. Therefore, we recommend the use of FRAX along with the prescribed medications to identify departments that admit high-risk patients.

Abstract
UNLABELLED This population-based cohort study with a 3-year follow-up revealed that the annual incidence rates of vertebral fracture (VF) and severe VF (sVF) were 5.9%/year and 1.7%/year, respectively. The presence of mild VF at the baseline was a significant risk factor for incident sVF in participants without prevalent sVF. INTRODUCTION This study aimed to estimate the incidence of morphometric vertebral fracture (VF) and severe VF (sVF) in men and women and clarify whether the presence of a mild VF (mVF) increases the risk of incident sVF. METHODS Data from the population-based cohort study, entitled the Research on Osteoarthritis/Osteoporosis Against Disability (ROAD) study, were analyzed. In total, 1190 participants aged ≥ 40 years (mean age, 65.0 ± 11.2) years completed whole-spine lateral radiography both at the third (2012-2013, baseline) and fourth surveys performed 3 years later (2015-2016, follow-up). VF was defined using Genant's semi-quantitative (SQ) method: VF as SQ ≥ 1, mVF as SQ = 1, and sVF as SQ ≥ 2. Cumulative incidence of VF and sVF was estimated. Multivariate logistic regression analyses were performed to evaluate risk factors for incident sVF. RESULTS The baseline prevalence of mVF and sVF were 16.8% and 6.0%, respectively. The annual incidence rates of VF and sVF were 5.9%/year and 1.7%/year, respectively. The annual incidence rates of sVF in participants without prevalent VF, with prevalent mVF, and with prevalent sVF were 0.6%/year, 3.8%/year, and 11.7%/year (p < 0.001), respectively. Multivariate logistic regression analyses in participants without prevalent sVF showed that the adjusted odds ratios for incident sVF were 4.12 [95% confident interval 1.85-9.16] and 4.53 [1.49-13.77] if the number of prevalent mVF at the baseline was 1 and ≥ 2, respectively. CONCLUSIONS The annual incidence rates of VF and sVF were 5.9%/year and 1.7%/year, respectively. The presence of prevalent mVF was an independent risk factor for incident sVF.

Much lower prevalence and severity of radiographic osteoporotic vertebral fracture in elderly Hong Kong Chinese women than in age-matched Rome Caucasian women: a cross-sectional study. Arch Osteoporos 2021; 16:174. [PMID: 34783904 DOI: 10.1007/s11657-021-00987-6] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/18/2021] [Accepted: 08/17/2021] [Indexed: 02/03/2023]
Abstract
INTRODUCTION Many earlier studies reported that East Asians and Caucasians have similar radiographic osteoporotic vertebral fracture (OVF) prevalence. Since elderly Chinese's osteoporotic hip fracture prevalence is half (or less than half) of that of their age-match Caucasians, we hypothesize that elderly Chinese's OVF prevalence could be only half, or even less than half, of that of their age-match Caucasians. MATERIALS Age-matched (mean: 74.1 years; range: 65-87 years) elderly women's radiographs (T4-L5) were from two OVF population-based epidemiological studies conducted in Hong Kong (n = 200) and in Rome (n = 200). All radiographs were double read by one reader in Hong Kong and one reader in Rome. Radiological osteoporotic vertebral deformity (ROVD) classification included no ROVD (grade 0), and ROVDs with < 20%, 20 ~ 25%, ≥ 25% ~ 1/3, ≥ 1/3 ~ 40%, ≥ 40% ~ 2/3, and ≥ 2/3 height loss (grade 1 ~ 6) as well as endplate/cortex fracture (ECF). Spinal deformity index (SDI) was calculated with each vertebra assigned a score of 0, 0.5, 1, 1.5, 2, 2.5, and 3 for no ROVD or ROVDs grade 1 ~ 6. RESULTS Seventy-seven (38.5%) Chinese subjects and 123 Italian subjects (61.5%) had ROVD respectively (p < 0.0001). Chinese subjects had ECF in 52 (26%) cases involving 100 vertebrae, while Italian subjects had ECF in 93 (47%) cases involving 230 vertebrae. ROVDs in Italian subjects tended to be more severe (total and mean SDI: 454.5 and 3.71 for Italian, and 212 and 2.72 for Chinese, p < 0.05), more likely to be multiple, more likely to have severe and collapsed grades. The slope of the relationship between age vs. SDI was steeper for the Italian subjects than for the Chinese subjects, suggesting ROVD severity developed faster for aging Italian subjects. A trend suggested earlier onset of ROVD among Italian. CONCLUSION OVFs in Chinese women tend to be less common, less severe, and less likely to have multiple fractures.

Abstract
INTRODUCTION Red blood cell distribution width (RDW) has been evaluated as a potential screening marker for cancer and prognostic marker in heart failure and coronary heart disease. Recent studies have been suggested the association of RDW with mortality in patients with hip fracture and arthroplasty. Objective of this study was to investigate whether RDW as a prognostic marker is significant in patients with osteoporotic vertebral fracture (OVF). MATERIALS AND METHODS Total of 460 patients with fresh OVF from January 2014 and September 2017 were assessed for a 1-year follow-up period. The cutoff value for RDW was set at 15%, and outcomes of conservative treatment of OVF were evaluated using the Japanese Orthopaedic Association (JOA) scores, Barthel index, and walking state. RESULTS Of the total 460 patients, 125 patients (27.2%) had an elevated RDW. RDW value was not correlated with osteoporotic parameters. Both JOA score and Barthel index were significantly lower at 1 year after treatment in the elevated RDW group. In the elevated RDW group, 21 patients died within 1 year (mortality 16.8%) compared with 7 patients (mortality 2.1%) in the non-elevated RDW group; this was statistically significant. Multivariate statistical analysis showed elevated RDW, independent walk before OVF and skeletal muscle mass index (SMI) remained independent factors associated with abasia after OVF affected. CONCLUSION Elevated RDW was associated with the poor clinical outcomes of conservative treatment of an OVF, independent of osteoporosis or severity of the OVF. RDW provides prognostic information for risk stratification as a senescence biomarker.

Abstract
UNLABELLED This study assessed the cost effectiveness of romosozumab versus teriparatide, both sequenced to alendronate, for the treatment of severe postmenopausal osteoporosis in Japan, using bone mineral density (BMD) efficacy data. Results show that romosozumab/alendronate produces greater health benefits at a lower cost than teriparatide/alendronate. INTRODUCTION This study aims to assess the cost effectiveness of romosozumab versus teriparatide, both sequenced to alendronate, for the treatment of severe postmenopausal osteoporosis in Japanese women previously treated with bisphosphonates. METHODS A Markov model was used to assess the relative cost effectiveness of 1 year of romosozumab versus 2 years of teriparatide, both sequenced to alendronate for a total treatment duration of 5 years. Outcomes for a cohort of women with a mean age of 78 years, a T-score ≤-2.5 and a previous fragility fracture were simulated over a lifetime horizon. The analysis was conducted from the perspective of the Japanese healthcare system and used a discount rate of 2% per annum. To inform relative fracture incidence, the bone mineral density (BMD) advantage of romosozumab over teriparatide was translated into relative risks of fracture, using relationships provided by a meta-regression of osteoporosis therapy trials. Outcomes were assessed in terms of lifetime costs (2020 US dollars) and quality-adjusted life years (QALYs). RESULTS Base case results showed that, compared with teriparatide/alendronate, romosozumab/alendronate reduced costs by $5134 per patient and yielded 0.045 additional QALYs. Scenario analyses and probabilistic sensitivity analysis confirmed that results are robust to uncertainty in model assumptions and inputs. CONCLUSION Results show that romosozumab/alendronate produces greater health benefits at a lower total cost than teriparatide/alendronate.

Abstract
Osteoporosis is a bone disease classified by deterioration of bone microarchitecture and decreased bone strength, thereby increasing subsequent risk of fracture. In the United States, approximately 54 million adults aged 50 years and older have osteoporosis or are at risk due to low bone mass. Osteoporosis has long been viewed as a chronic health condition affecting primarily non-Hispanic white (NHW) women; however, emerging evidence indicates racial and ethnic disparities in bone outcomes and osteoporosis management. The primary objective of this review is to describe disparities in bone mineral density (BMD), prevalence of osteoporosis and fracture, as well as in screening and treatment of osteoporosis among non-Hispanic black (NHB), Hispanic, and Asian adults compared with NHW adults living on the US mainland. The following areas were reviewed: BMD, osteoporosis prevalence, fracture prevalence and incidence, postfracture outcomes, DXA screening, and osteoporosis treatments. Although there are limited studies on bone and fracture outcomes within Asian and Hispanic populations, findings suggest that there are differences in bone outcomes across NHW, NHB, Asian, and Hispanic populations. Further, NHB, Asian, and Hispanic populations may experience suboptimal osteoporosis management and postfracture care, although additional population-based studies are needed. There is also evidence that variation in BMD and osteoporosis exists within major racial and ethnic groups, highlighting the need for research in individual groups by origin or background. Although there is a clear need to prioritize future quantitative and qualitative research in these populations, initial strategies for addressing bone health disparities are discussed. © 2021 American Society for Bone and Mineral Research (ASBMR).

Abstract
INTRODUCTION The presence of existing osteoporotic vertebral fracture (OVF) increases the mortality risk. However, the influence of the characteristics of OVF is unclear. This study aimed to investigate the influence of new OVF on patients' long-term prognosis using our past cohort study. METHOD This is an extension study of our cohort study carried out between 2005 and 2007. In the present extension study, of 420 patients, 197 whose contact information was available at the 6-month follow-up were included in the telephone survey in 2018. Five patients refused to participate in the survey, and 82 could not be contacted. Eventually, 110 patients were enrolled. Of the Demographic data, radiological findings, medical history, and clinical outcome were investigated at injury onset and at the 6-month follow-up. A proportional hazard model was used to investigate the risk factors for mortality. RESULTS Among 110 patients, 33 died. Male sex and low body mass index (BMI <18.5 kg/m2) were significant risk factors for mortality [hazard ratio (HR) = 6.40, 1.01-40.50; 5.24, 1.44-19.04, respectively]. The history of stroke and liver disease increased the risk of mortality (HR = 13.37, 1.93-92.7; 6.62, 1.15-38.14, respectively). As regards radiological findings, local kyphosis progression per 1° or ≥7° were significant risk factors of mortality (HR = 1.20, 1.06-1.36; 5.38, 1.81-16.03, respectively). CONCLUSIONS A telephone survey at 12 years after the occurrence of OVF analyzed risk factors for mortality and showed that a progression of local kyphosis in fractures between injury onset and 6 months after injury was a risk factor of poor prognosis.

Abstract
Study Design A prospective cohort study. Purpose This study aimed to reveal physical functions and comorbidity affecting collapse at ≥4 weeks after hospital admission of patients with osteoporotic vertebral fracture. Overview of Literature Only a few studies have investigated the influence of physical function and activity on collapse in patients with osteoporotic vertebral fractures. Methods This prospective cohort study analyzed patients with osteoporotic vertebral fractures admitted to the hospital between March 2018 and October 2019. Logistic regression analysis was performed to explore the predictors of vertebral collapse at >4 weeks after admission. Model 1 used basic medical information and physical functions at admission; model 2 used basic medical information and physical function and activity at >4 weeks after admission. Results In the model 1 results of logistic regression analysis, cardiovascular disease (odds ratio [OR], 12.27; 95% confidence interval [CI], 1.28–117.91) was extracted as a factor affecting vertebral collapse at ≥4 weeks after admission. In the model 2 results of logistic regression analysis, cardiovascular disease (OR, 34.57; 95% CI, 2.53–471.74), movement control during one leg standing at 4 weeks (OR, 7.25; 95% CI, 1.36–38.71), and Pain Catastrophizing Scale score at 4 weeks (OR, 1.11; 95% CI, 1.01–1.21) were extracted as factors affecting vertebral collapse at ≥4 weeks after admission. Conclusions Our results indicate that physical functions and comorbidity affect collapse at ≥4 weeks after admission in patients with osteoporotic vertebral fractures.

Abstract
OBJECTIVES This study aimed to identify factors, including physical functions and activities that affect quality of life (QOL) at discharge among patients with osteoporotic vertebral fractures. METHODS Patients with osteoporotic vertebral fractures were included in our prospective cohort study. Multiple regression analysis was performed to determine the predictors of QOL at discharge using two models: model 1, basic medical information and physical functions at admission, and model 2, basic medical information, physical function, and activity after 4 weeks of admission. RESULTS Multiple regression analysis (standard partial regression coefficients) using model 1 identified L2 to L4 bone mineral density (-0.2), Visual Analog Scale for pain during activity at admission (-0.31), and Revised Hasegawa Dementia Scale (HDS-R) score at admission (0.64) as factors affecting QOL at discharge. Multiple regression analysis using model 2 identified HDS-R at admission (0.64), Pain Catastrophizing Scale score at 4 weeks (-0.34), and knee extension muscle strength at 4 weeks (0.28) as factors affecting QOL at discharge. CONCLUSIONS Our results suggest that if patients have high bone mineral density, intense pain, and low cognitive function at admission, then low QOL at discharge will be predicted; however, improvement of pain catastrophizing and knee extension muscle strength during first the 4 weeks of admission may be able to improve QOL at discharge. Because patients in this study were Japanese only, it is important to exercise caution when applying our results to other populations.

Abstract
The increase in the incidence of hip fractures over time disappeared in Northern European and North American Caucasians after 2000, while an increase was observed in Asian countries including Japan until 2010. However, a decrease in the incidence was observed after 2010. The prevalence of vertebral fractures in Asians, Europeans, and American Caucasians is similar, and the incidences of clinical and morphometric vertebral fractures are higher in Asians compared with European Caucasians. The decrease in the incidence of vertebral fractures over time has been observed in Japan. Although the stabilization or decrease over time in the incidence of hip and vertebral fractures have been observed, the number of patients with these fractures is expected to increase rapidly with increases in the elderly population. Multidisciplinary measures to prevent fragility fractures are an urgent issue in Asia at this time. This narrative review outlines the recent trends in incidence and future burdens of hip fracture and vertebral fracture in Asia.

Abstract
Backgroud The purpose of this study was to investigate the characteristics of osteoporotic vertebral compression fractures (OVCFs) in Korean postmenopausal women and the association between OVCFs and clinical factors such as age, bone mineral density (BMD), and quality of life. Methods According to the population distribution in four regions in Korea, 1,281 postmenopausal female patients were recruited from nationwide orthopedic outpatient clinics. Radiologic, asymptomatic, and within 3 months of OVCF groups were analyzed based on age, fracture location, and prevalence according to BMD. In addition, BMD, T-score, body mass index, and European Quality of Life-5 Dimensions (EQ-5D) were investigated in the three groups, and the differences between groups were compared and analyzed. Results The prevalence of radiologic OVCFs at the T11–L1 was 3.7 times higher in the 70s group (44.0%) than in the 50s group (11.9%). Femur and total hip BMD were significantly lower in patients with thoracolumbar junction fractures than in patients with L2–5 fractures, whereas no difference was observed in lumbar spine BMD. Of the three OVCF groups, the within 3 months of OVCF group had the lowest lumbar spine T-score of −2.445. The asymptomatic OVCF group also showed significantly lower lumbar spine T-score than did the group without radiologic OVCFs (p < 0.001). The EQ-5D showed a significant decrease in the radiologic OVCF group (p < 0.001) and within 3 months of OVCF group (p < 0.001). Conclusions The prevalence of OVCFs in the thoracolumbar junction rapidly increases with old age and low BMD in Korean postmenopausal women. Femur and total hip BMD are more predictive of thoracolumbar junction fractures than lumbar spine BMD. Patients with radiologic OVCFs had a significantly lower quality of life than no OVCF group. Therefore, this study shows it is important to treat and prevent osteoporosis before an OVCF occurs.

Abstract
Study Design Combination of retrospective and prospective study. Purpose We aimed to compare the clinical outcomes between local fixation surgery and spinopelvic fixation surgery for the treatment of kyphosis secondary to osteoporotic vertebral fractures with spinopelvic malalignment. Overview of Literature The clinical characteristics of patients with rigid kyphosis due to osteoporotic vertebral fracture differ from that of middle-aged patients with vertebral fractures in terms of bone fragility and presence of spinopelvic malalignment. Little is known about the surgical strategies for these deformities, most especially the extent of fusion of vertebra involved. Methods We analyzed 24 patients with vertebral osteotomy at the level of the fracture and spinal fixation without pelvic fixation (local group), and 22 patients with vertebral osteotomy and pelvic fixation (pelvic group). Radiographic parameters, the incidence of proximal junctional kyphosis (PJK), distal junctional kyphosis (DJK), rod fractures, and the Oswestry Disability Index (ODI) were compared between the two groups over a 2-year follow-up period. Results In the pelvic group, postoperative spinopelvic parameters significantly improved, with the improvements maintained. No remarkable changes in spinopelvic parameters were seen in the local group. The mean ODI scores 2 years after surgery were 45.3 and 33.0 in the local and pelvic group, respectively (p-value <0.05). There was no significant difference in the incidence of PJK in the local and pelvic groups, but there was a higher rate of DJK (41.7%) in the local group. In contrast, rod fractures were more common in the pelvic group (45.5%). Patients with DJK had higher ODI scores 2 years after surgery (52.0 in DJK patients vs. 34.8 in non-DJK patients; p-value <0.05). Conclusions For patients with rigid kyphosis due to osteoporotic vertebral fractures, better spinopelvic alignment and health-related quality of life can be achieved through extensive corrective surgery with pelvic fixation.

Abstract
UNLABELLED We aim to investigate the nationwide prevalence of asymptomatic radiographic vertebral fracture in Thailand. We found 29% of postmenopausal women had at least one radiographic vertebral fracture. The prevalence was significantly higher among women with osteoporosis at the total hip (TH) region which implies that TH bone mineral density is a determinant of vertebral fracture risk. INTRODUCTION Radiographic vertebral fracture is associated with an increased risk of osteoporotic fracture and mortality in postmenopausal women. We designed a study to determine the prevalence of asymptomatic vertebral fractures in postmenopausal Thai women. METHODS The study was designed as a cross-sectional investigation at five university hospitals so as to achieve representation of the four main regions of Thailand. Radiographs were taken from 1062 postmenopausal women averaging 60 years of age. The presence of vertebral fracture was assessed by the Genant's semiquantitative method with three independent radiologists. Respective bone mineral density was measured by dual-energy X-ray absorptiometry (DEXA) at the lumbar spine (LS), femoral neck (FN), and total hip (TH). RESULTS Among the 1062 women, 311 were found to have at least one radiographic vertebral fracture-yielding a prevalence of 29% (95% CI 23.6-32.0%)-and 90 (8.5%, 95% CI 6.8-10.2%) had at least two fractures. The prevalence of vertebral fracture increased with advancing age. Most fractures occurred at one vertebra (71%) and only 29% at multiple vertebrae. The prevalence of vertebral fracture was significantly higher among women with osteoporosis compared with non-osteoporosis at the TH region. There was no significant difference in the prevalence among women with or without osteoporosis at the LS or FN. CONCLUSIONS Radiographic vertebral fractures were common among Thai postmenopausal women (~ 29%). These findings suggest that approximately one in three postmenopausal women has undiagnosed vertebral fracture. Radiographic diagnosis should therefore be an essential investigation for identifying and confirming the presence of vertebral fractures.

Abstract
BACKGROUND AND PURPOSE Most patients become physically inactive after vertebral compression fracture and thus need help for early mobilization. This study sought to investigate the effect of early rehabilitation on activities of daily living in patients following acute vertebral compression fracture. METHODS We conducted this retrospective cohort study with a hospital-based database created by the Japan Medical Data Center and comprising data from a Diagnosis Procedure Combination survey from more than 100 acute care hospitals across Japan. Data of consecutive inpatients hospitalized because of thoracic and/or lumbar compression fractures from 2014 to 2018 were extracted. We compared characteristics and outcomes between patients who underwent early rehabilitation (early rehabilitation group) and those who did not undergo rehabilitation (no rehabilitation group). The primary outcome measure was Barthel Index improvement. RESULTS After applying exclusion criteria, a total of 8493 eligible patients with acute vertebral compression fracture were included in this study. The unadjusted data showed significantly greater Barthel Index improvement (72.5% vs 60.3, P < .001) and a higher rate of discharge to home (82.9% vs 77.4, P < .001) among patients in the early rehabilitation group compared with the no rehabilitation group. After adjustment by propensity score analysis, significant between-group differences were found. CONCLUSION Early rehabilitation could possibly be a feasible alternative for maintenance of the Barthel Index in patients with acute vertebral compression fracture.

Abstract
The objective of the present multicenter randomized study was to compare weekly teriparatide with alendronate in their inhibition of vertebral collapse, effects on delayed union, pain relief, and improvement of quality of life (QOL) in women with new osteoporotic vertebral fractures within 1 week after onset of the fracture. Patients were randomly allocated to the teriparatide and alendronate groups. Vertebral collapse, low back pain assessed by a visual analog scale, and QOL assessed by EuroQol 5 dimension at weeks 1, 2, 4, 8, and 12 after the start of the treatment were compared between the groups. Lumbar bone mineral density (BMD) at baseline and week 12 and the rate of delayed union at week 12 were also compared. Each group consisted of 48 subjects. Vertebral collapse progressed over time in both groups, with no significant difference between the groups. Pain on rising up from lying position, turning over in bed, and resting in the lying position improved over time in both groups, with no significant difference between the groups. There were no significant differences in increase in BMD and delayed union. QOL in the teriparatide group showed significant improvement in comparison with that in the alendronate group at week 12. The weekly formulation of teriparatide showed comparable inhibition of vertebral collapse, increase in BMD, promotion of bone union, and improvement of pain and significant improvement of QOL at week 12 in comparison with alendronate in patients with a new osteoporotic vertebral fracture within 1 week after onset of the fracture. The weekly formulation of teriparatide may have improved components of QOL other than pain at week 12.

Dimorphism in axial and appendicular dimensions, cortical and trabecular microstructure and matrix mineral density in Chinese and Caucasian women. Bone 2019; 128:115039. [PMID: 31437567 DOI: 10.1016/j.bone.2019.115039] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/24/2019] [Revised: 08/02/2019] [Accepted: 08/16/2019] [Indexed: 12/27/2022]
Abstract
INTRODUCTION Appendicular fractures are less common in Chinese than Caucasian women. Bone mineral density (BMD) is lower, not higher than in Caucasians because Chinese have smaller appendicular dimensions than Caucasians. However, smaller bones may offset the liability to fracture by being assembled with a more robust microstructure. We hypothesized that Chinese assemble an appendicular skeleton with a thicker, less porous and more mineralized cortex that is less deteriorated in advanced age than in Caucasians. METHODS We compared anthropometry in 477 Chinese and 278 Caucasian women and compared bone microstructure using high-resolution peripheral quantitative computed tomography in another cohort of 186 Chinese and 381 Caucasian women aged 18 to 86 years, all living in Melbourne, Australia. Trabecular plate (p) and rod (r) bone volume/total volume (BV/TV) were quantified using individual trabecula segmentation (ITS). Bone strength was estimated using micro-finite element analysis (μFEA). RESULTS Premenopausal Chinese were shorter than Caucasian women, mainly due to shorter leg length. Distal radial total cross sectional area (CSA) was 14.8% smaller (p < 0.001). After adjusting for age and total CSA, Chinese had similar cortical and medullary areas but 0.30 SD lower cortical porosity and 0.27 SD higher matrix mineral density (both p < 0.05). Trabecular plate-to-rod ratio was 0.55 SD higher due to a 0.41 SD higher pBV/TV and 0.36 SD lower rBV/TV (p ranging 0.001 to 0.023). Chinese also had 0.36 SD greater whole bone stiffness and 0.36 SD greater failure load than Caucasians (both p < 0.05). After adjusting for age and total CSA, postmenopausal Chinese had 3.3% smaller cortical area, medullary area was 2.1% larger, cortical porosity was no lower, matrix mineral density and pBV/TV were no higher compared with Caucasians at the distal radius. Whole bone stiffness was 0.39 SD lower and failure load was 0.40 SD lower in Chinese (both p < 0.05). CONCLUSION Chinese build a more robust skeleton than Caucasians during growth, an advantage not observed in advanced age due to greater bone loss or race-specific secular trends in bone morphology.

Abstract
Background Osteoporosis is a major global public health problem in the current aging era. Osteoporosis is often diagnosed only after patients have a fracture that causes a severe decline in ability to perform activities of daily life. Although the current criterion standard for diagnosing osteoporosis is dual-energy X-ray absorptiometry (DXA), this modality remains less prevalent among general practitioners in geriatric medicine. The aim of this study was to determine the diagnostic utility of visual inspection of lumbar radiography in detecting bone mineral density (BMD) decline. Material/Methods We retrospectively reviewed medical data of 78 patients who underwent both lateral lumbar radiography and DXA. Board-certified radiologists determined the clinical grade of each patient’s condition according to the semiquantitative (SQ) method of lumbar fracture assessment. We compared the grades and young adult means of BMD in the lumbar spine and hips as measured using DXA. Results BMD of the femoral neck was significantly lower in patients with severe osteoporosis (grades 2 and 3 as classified using the SQ method) than in those with mild osteoporosis (grades 0 and 1; P<0.05). A receiver operating characteristic curve analysis showed that the SQ method can help predict the decrease in BMD (young adult mean score of <70%) in the femoral neck with moderate accuracy (sensitivity, 0.621; specificity, 0.829; area under the curve, 0.742). Conclusions These results suggest that lateral lumbar radiography can provide useful information about bone mineral status and can serve as a tool for osteoporosis screening by general practitioners.

Abstract
The objective of this study was to investigate the incidence of vertebral fractures (VFx) and the value of physical function (PF) and body composition (BC) for predicting VFx in a Japanese population. This study included 307 subjects (113 men, 194 women) at least 40 years of age who were assessed at community health check-ups in 2008 and 2016. PF was assessed by grip strength and by single-leg stance, timed up-and-go, and 30-s chair stand tests, each scored from 0 to 3 for a possible total of 12 points (higher scores reflect lower function). BC was scored on bioelectrical impedance measurements of trunk and appendage muscle volume, with 6 possible points. We diagnosed radiological VFx semiquantitatively on lateral views of the lumbar spine, and measured bone mineral status by quantitative ultrasound (QUS) of the calcaneus. We conducted logistic regression analysis with VFx as the dependent variable and age, sex, BMI, QUS, PF score, and BC score as independent variables. In 8 years, 36 participants (12%) sustained new VFx. After correcting for age, sex, BMI, and QUS, the odds of VFx increased with a PF score ≥ 8 (OR 5.6; 95% CI 1.21-25.90; P = 0.028) and increased further with a PF + BC score ≥ 9 (OR 8.1; 95% CI 1.80-36.00; P < 0.01). Both PF and BC are important for predicting fragility fractures. The scoring system used here may reflect small differences better than categorical (single cutoff) definitions of poor function.

Abstract
STUDY DESIGN A propensity score matching study. OBJECTIVE The aim of this study was to assess the cost-effectiveness of balloon kyphoplasty (BKP) in Japan. SUMMARY OF BACKGROUND DATA Osteoporotic vertebral fracture (OVF) is a common disease in elderly people. In Japan, the incidence of painful OVF in 2008 was estimated as 880,000, and approximately 40% of patients with painful OVF are hospitalized due to the severity of pain. Japan is the front runner among super-aged societies and rising health care costs are an economic problem. METHODS BKP and nonsurgical management (NSM) for acute/subacute OVF were performed in 116 and 420 cases, respectively. Quality-adjusted life years (QALY) and incremental costs were calculated on the basis of a propensity score matching study. QALY was evaluated using the SF-6D questionnaire. Finally, using a Markov model, incremental cost-effectiveness ratios (ICERs) were calculated for 71 matched cases. RESULTS In the comparison between BKP and NSM, mean patients age was 78.3 and 77.7 years, respectively (P = 0.456). The BKP procedure cost 402,988 JPY more than NSM and the gains in QALY at the 6-month follow-up were 0.153 and 0.120, respectively (difference = 0.033). ICERs for 3 and 20 years were 4,404,158 JPY and 2,416,406 JPY, respectively. According to sensitivity analysis, ICERs ranged from 652,181 JPY to 4,896,645 JPY (4418-33,168 GBP). CONCLUSION This study demonstrated that BKP is a cost-effective treatment option for OVF in Japan. However, the effect might be blunted in patients aged > 80 years. Further research is necessary to elucidate the cost-effectiveness of BKP in this population. LEVEL OF EVIDENCE 4.

Abstract
UNLABELLED A model-based cost-effectiveness analysis was performed to evaluate the cost-effectiveness of implementing the clinical guideline for the treatment for glucocorticoid-induced osteoporosis (GIO). The treatment indication for GIO in the current Japanese clinical guidelines is likely to be cost-effective except for the limited patients who are at low risk for fracture. INTRODUCTION The purpose of this study was to evaluate the cost-effectiveness of implementing the clinical guideline for the treatment for glucocorticoid-induced osteoporosis (GIO) from the perspective of the Japanese healthcare system. METHODS A patient-level state transition model was developed to predict lifetime costs and quality-adjusted life years (QALYs) in postmenopausal Japanese women with osteopenia or osteoporosis using glucocorticoid (GC). An annual discount rate of 2% for both costs and QALYs was applied. The incremental cost-effectiveness ratio (ICER) of 5-year alendronate therapy compared with no therapy was estimated with different combinations of the risk factors such as starting age (45, 55, or 65), femoral neck BMD (% young adult mean (YAM) of 70%, 75%, or 80%), dose of GC (2.5, 5, or 10 mg per day), and the presence of previous fracture (yes or no). RESULTS For 55-year-old women using GC with a BMD of 75% of YAM, the ICER ranged from $10,958 to $ 29,727 per QALY. Scenario analyses indicated that the lower age, the lower BMD, the higher dose of GC, and the presence of previous fracture associated with lower ICER. The best-case scenario was 45-year-old women with a BMD of 70% of YAM, GC dose of 10 mg per day, and previous fracture, and resulted in healthcare cost-savings. The worst-case scenario was 65-year-old women with a BMD of 80% of YAM, GC dose of 2.5 mg per day, and no previous fracture, and resulted in the ICER of $66,791 per QALY. Sensitivity analyses in the worst-case scenario showed that the annual discount rate for costs and health benefit had the strong influence on the estimated ICER. Although the ICER was influenced by other parameters such as disutility due to vertebral fracture, efficacy of alendronate, and so on, the ICERs remained more than $50,000 per QALY. CONCLUSIONS The cost-effectiveness of preventive alendronate therapy for postmenopausal women with osteopenia or osteoporosis using GC is sensitive to age, BMD, GC dose, and the presence of previous fracture. Our analysis suggested that the treatment indication for postmenopausal women with osteopenia or osteoporosis using GC in the current Japanese clinical guidelines is likely to be cost-effective except for the limited patients who are at low risk for fracture.

Abstract
OBJECTIVES The purpose of this study was to investigate the treatment outcomes and prognostic factors of medication-related osteonecrosis of the jaw (MRONJ) in Japanese patients. PATIENTS AND METHODS Among 409 cases, treatment outcomes and prognostic factors were investigated in 275 patients. In statistical analyses, the 1-year cumulative curative rate was calculated with the Kaplan-Meier method, and significance was examined with the Wilcoxon test. Cox's proportional hazards regression analysis was used for the multivariate analysis. RESULTS Resolution of the disease was achieved in 137 out of 275 MRONJ patients (49.8%). One-year cumulative curative rates were 39.8% in stage 1 patients, 26.3% in stage 2, and 19.0% in stage 3. The 1-year cumulative curative rates of treatment interventions were 17.2% for conservative treatment, 34.5% for sequestrectomy, and 40.7% for extended surgery including bone resection and segmental resection. As the prognostic factors of treatment outcomes, the type of medication, stage of MRONJ, and type of surgical intervention were identified as independent factors in a multivariate analysis. CONCLUSION These results suggest that surgical interventions may lead to a good prognosis in MRONJ patients. CLINICAL RELEVANCE This study indicated that surgical intervention for MRONJ might lead to improvement of prognosis and quality of life in MRONJ patients.

Abstract
Introduction Osteoporosis is a pathological state with an unbalanced bone metabolism mainly caused by accelerated osteoporotic osteoclast activity due to a postmenopausal estrogen deficiency, and it causes some kinds of pain, which can be divided into two types: traumatic pain due to a fragility fracture from impaired rigidity, and pain derived from an osteoporotic pathology without evidence of fracture. We aimed to review the concepts of osteoporosis-related pain and its management. Methods We reviewed clinical and basic articles on osteoporosis-related pain, especially with a focus on the mechanism of pain derived from an osteoporotic pathology (i.e., osteoporotic pain) and its pharmacological treatment. Results Osteoporosis-related pain tends to be robust and acute if it is due to fracture or collapse, whereas pathology-related osteoporotic pain is vague and dull. Non-traumatic osteoporotic pain can originate from an undetectable microfracture or structural change such as muscle fatigue in kyphotic patients. Furthermore, basic studies have shown that the osteoporotic state itself is related to pain or hyperalgesia with increased pain-related neuropeptide expression or acid-sensing channels in the local tissue and nervous system. Traditional treatment for osteoporotic pain potentially prevents possible fracture-induced pain by increasing bone mineral density and affecting related mediators such as osteoclasts and osteoblasts. The most common agent for osteoporotic pain management is a bisphosphonate. Other non-osteoporotic analgesic agents such as celecoxib have also been reported to have a suppressive effect on osteoporotic pain. Conclusions Osteoporotic pain has traumatic and non-traumatic factors. Anti-osteoporotic treatments are effective for osteoporotic pain, as they improve bone structure and the condition of the pain-related sensory nervous system. Physicians should always consider these matters when choosing a treatment strategy that would best benefit patients with osteoporotic pain.

Abstract
Fragility fractures in the elderly is an ongoing concern for orthopaedic surgeons. A 50-year-old woman has a 40% chance of having a vertebral compression fracture in her lifetime. The incidence of vertebral fractures, reported to be more than 10 times higher than that of femoral fractures, is estimated as 1–1.5 million per year in Japan. Vertebral fractures often occur without a fall, whereas the majority of nonvertebral fractures are the consequence of falls; the site of the nonvertebral fracture appears to be dictated by the type of fall. Distal radial fractures commonly occur as a consequence of hand protection during the fall. In older patients, falling load tends to directly affect shoulder and hip joints and lead to proximal humeral and femoral fractures. The incidence of vertebral fractures is increased in women over 50 yr of age, following the same trend as osteoporosis prevalence. Conversely, the mean age for proximal femoral fractures is around 80 yr, and more than 75% of femoral fractures occur in individuals over the age of 75. The prognostic risk of aging is 11-fold greater than that of reduced bone mineral density, and age is another risk factor for femoral fractures. Prophylactic therapy for osteoporosis and femoral fractures was shown to more effective in women in their 70s than in those over the age of 80. Although several approaches, including exercise therapy, vitamin D administration, and environmental adjustment at home, have been reported to be effective in fall prevention, effective fracture prevention approaches in frail elderly individuals have not yet been well established.

Abstract
AIMS/INTRODUCTION There are various causes of incident bone fracture. Not only aging, low bone mineral density and history of previous fracture, but also diabetes mellitus and inflammation are regarded as risk factors for fracture. The purpose of the present study was to verify the association of glycemic control or one inflammatory marker with incident fracture in a large-scale Japanese cohort. MATERIALS AND METHODS The present study was carried out at the Hiroshima Atomic Bomb Casualty Council and included 6,556 participants (2,785 men and 3,771 women, aged 55-87 years) who underwent annual health examinations and were followed for 7.4 years. Information about incident fractures was collected at interviews. Participants were classified into three groups: normal, borderline and diabetes mellitus according to glycohemoglobin levels (treated diabetes patients were included in the diabetes mellitus group). Furthermore, participants were classified into four additional groups by glycemic control (diabetes mellitus or non-diabetes mellitus) and C-reactive protein (CRP) levels (low or high). Hazard ratios (HRs) of diabetes mellitus, CRP and their combined risk of incident fracture were evaluated. RESULTS After adjusting for age, bone mineral density and previous fracture, CRP was associated with increased fracture risk (in men HR 1.04, 95% confidence interval [CI]: 1.003-1.06; in women HR 1.07, 95% CI: 1.03-1.13), and diabetes mellitus predicted fracture risk in men (HR 1.31, 95% CI: 1.02-1.51). Fracture risk was significantly higher among the diabetes mellitus with high CRP group compared with the non-diabetes mellitus with low CRP group (in men HR 1.47, 95% CI: 1.02-1.98; in women HR 1.41, 95% CI: 1.04-1.92). CONCLUSIONS Among a Japanese cohort, CRP measurements were helpful to detect high fracture risk in patients with type 2 diabetes mellitus.

Abstract
UNLABELLED Model-based economic evaluation was performed to assess the cost-effectiveness of zoledronic acid. Although zoledronic acid was dominated by alendronate, the incremental quality-adjusted life year (QALY) was quite small in extent. Considering the advantage of once-yearly injection of zoledronic acid in persistence, zoledronic acid might be a cost-effective treatment option compared to once-weekly oral alendronate. INTRODUCTION The purpose of this study was to estimate the cost-effectiveness of once-yearly injection of zoledronic acid for the treatment of osteoporosis in Japan. METHODS A patient-level state-transition model was developed to predict the outcome of patients with osteoporosis who have experienced a previous vertebral fracture. The efficacy of zoledronic acid was derived from a published network meta-analysis. Lifetime cost and QALYs were estimated for patients who had received zoledronic acid, alendronate, or basic treatment alone. The incremental cost-effectiveness ratio (ICER) of zoledronic acid was estimated. RESULTS For patients 70 years of age, zoledronic acid was dominated by alendronate with incremental QALY of -0.004 to -0.000 and incremental cost of 430 USD to 493 USD. Deterministic sensitivity analysis indicated that the relative risk of hip fracture and drug cost strongly affected the cost-effectiveness of zoledronic acid compared to alendronate. Scenario analysis considering treatment persistence showed that the ICER of zoledronic acid compared to alendronate was estimated to be 47,435 USD, 27,018 USD, and 10,749 USD per QALY gained for patients with a T-score of -2.0, -2.5, or -3.0, respectively. CONCLUSION Although zoledronic acid is dominated by alendronate, the incremental QALY is quite small in extent. Considering the advantage of annual zoledronic acid treatment in compliance and persistence, zoledronic acid may be a cost-effective treatment option compared to alendronate.

Abstract
UNLABELLED A model-based cost-effectiveness analysis was performed to evaluate the cost-effectiveness of secondary fracture prevention by osteoporosis liaison service (OLS) relative to no therapy in patients with osteoporosis and a history of hip fracture. Secondary fracture prevention by OLS is cost-effective in Japanese women with osteoporosis who have suffered a hip fracture. INTRODUCTION The purpose of this study was to estimate, from the perspective of Japan's healthcare system, the cost-effectiveness of secondary fracture prevention by OLS relative to no therapy in patients with osteoporosis and a history of hip fracture. METHODS A patient-level state transition model was developed to predict lifetime costs and quality-adjusted life years (QALYs) in patients with or without secondary fracture prevention by OLS. The incremental cost-effectiveness ratio (ICER) of secondary fracture prevention compared with no therapy was estimated. Sensitivity analyses were performed to examine the influence of parameter uncertainty on the base case results. RESULTS Compared with no therapy, secondary fracture prevention in patients aged 65 with T-score of -2.5 resulted in an additional lifetime cost of $3396 per person and conferred an additional 0.118 QALY, resulting in an ICER of $28,880 per QALY gained. Deterministic sensitivity analyses showed that treatment duration and offset time strongly affect the cost-effectiveness of OLS. According to the results of scenario analyses, secondary fracture prevention by OLS was cost-saving compared with no therapy in patients with a family history of hip fracture and high alcohol intake. CONCLUSIONS Secondary fracture prevention by OLS is cost-effective in Japanese women with osteoporosis who have suffered a hip fracture. In addition, secondary fracture prevention is less expensive than no therapy in high-risk patients with multiple risk factors.

Abstract
UNLABELLED Although an osteoporosis screening program has been implemented as a health promotion project in Japan, its cost-effectiveness has yet to be elucidated fully. We performed a cost-effectiveness analysis and found that osteoporosis screening and treatment would be cost-effective for Japanese women over 60 years. INTRODUCTION The purpose of this study was to estimate the cost-effectiveness of osteoporosis screening and drug therapy in the Japanese healthcare system for postmenopausal women with no history of fracture. METHODS A patient-level state transition model was developed to predict the outcomes of Japanese women with no previous fracture. Lifetime costs and quality-adjusted life years (QALYs) were estimated for women who receive osteoporosis screening and alendronate therapy for 5 years and those who do not receive the screening and treatments. The incremental cost-effectiveness ratio (ICER) of the screening option compared with the no screening option was estimated. Sensitivity analyses were performed to examine the influence of parameter uncertainty on the base case results. RESULTS The ICERs of osteoporosis screening and treatments for Japanese women aged 50-54, 55-59, 60-64, 65-69, 70-74, and 75-79 years were estimated to be $89,242, $64,010, $40,596, $27,697, $17,027, and $9771 per QALY gained, respectively. Deterministic sensitivity analyses showed that several parameters such as the disutility due to vertebral fracture had a significant influence on the base case results. Applying a willingness to pay of $50,000 per QALY gained, the probability that the screening option became cost-effectiveness estimated to 50.9, 56.3, 59.1, and 64.7 % for women aged 60-64, 65-69, 70-74, and 75-79 years, respectively. Scenario analyses showed that the ICER for women aged 55-59 years with at least one clinical risk factor was below $50,000 per QALY. CONCLUSIONS In conclusion, dual energy X-ray absorptiometry (DXA) screening and alendronate therapy for osteoporosis would be cost-effective for postmenopausal Japanese women over 60 years. In terms of cost-effectiveness, the individual need for osteoporosis screening should be determined by age and clinical risk factors.

Abstract
In a 2-year randomized, placebo-controlled study of 665 Japanese patients with primary osteoporosis, once-yearly administration of zoledronic acid (5 mg) reduced the risk of new morphometric vertebral fractures. INTRODUCTION The purpose of this study was to determine the efficacy and safety of once-yearly intravenous infusion of ZOL in Japanese patients with primary osteoporosis. METHODS This was a two-year multicenter, randomized, placebo-controlled, double-blind, parallel-group comparative study (ZONE Study). Subjects were 665 Japanese patients between the ages of 65 and 89 years who had prevalent vertebral fracture. Subjects were randomly assigned to receive once-yearly intravenous infusion of 5 mg of ZOL or placebo at baseline and 12 months. RESULTS The 2-year incidence of new morphometric vertebral fracture was 3.0 % (10/330 subjects) in the ZOL group and 8.9 % (29/327) in the placebo group (p = 0.0016). The 24-month cumulative incidence of new morphometric vertebral fracture was 3.3 % in the ZOL group versus 9.7 % in the placebo group (log-rank test: p = 0.0029; hazard ratio: 0.35; 95 % confidence interval: 0.17-0.72). The cumulative incidence of any clinical fracture, clinical vertebral fracture, and non-vertebral fracture was significantly reduced in the ZOL group by 54, 70, and 45 %, respectively, compared to the placebo group. At 24 months, ZOL administration increased bone mineral density in the lumbar spine, femoral neck, and total hip (t test: p < 0.0001). No new adverse events or osteonecrosis of the jaw were observed in this study. CONCLUSIONS Once-yearly administration of ZOL 5 mg to Japanese patients with primary osteoporosis reduced the risk of new morphometric vertebral fractures and was found to be safe.

Abstract
OBJECTIVE In the very elderly, their general condition and poor compliance with drug regimens can render the treatment of low back pain (LBP) difficult. We report the effectiveness of a less-invasive treatment for intractable LBP from superior cluneal nerve entrapment neuropathy (SCN-EN) and gluteus medius muscle (GMeM) pain. PATIENTS AND METHODS Between April 2013 and March 2015, we treated 17 consecutive elders with LBP, buttock pain, and leg pain. They were 4 men and 13 women ranging in age from 85 to 91 years (mean 86.6 years). We carefully ascertained that their symptoms were attributable to SCN-EN and GMeM pain. The median follow-up period was 21.5 ± 12.2 months (range 2-35 months). RESULTS SCN-EN was diagnosed in 15 patients (28 sites) and GMeM pain in 14 (27 sites). In 5 patients, we obtained symptom control by local block (Numerical Rating Scale for LBP: declined from 7.8 to 0.8 [P < 0.05], Roland-Morris Disability Questionnaire score: declined from 16.5 to 5.2). The other 12 were operated under local anesthesia (SCN neurolysis, GMeM decompression). As 3 patients reported the persistence of leg pain postoperatively, they subsequently underwent peroneal nerve neurolysis and surgery for tarsal tunnel syndrome. These treatments resulted in significantly symptom abatement (Numerical Rating Scale: from 8.2 to 1.7, Roland-Morris Disability Questionnaire score: from 12.8 to 8.6; P < 0.05). CONCLUSIONS Even very old patients with intractable LBP, buttock pain, and leg pain due to SCN-EN or GMeM pain can be treated successfully by peripheral block and less-invasive surgery under local anesthesia.

Significance of the Pars Interarticularis in the Cortical Bone Trajectory Screw Technique: An In Vivo Insertional Torque Study. Asian Spine J 2016; 10:901-906.

Abstract
STUDY DESIGN Retrospective study. PURPOSE Cortical bone trajectory (CBT), a more medial-to-lateral and shorter path than the traditional one for spinal fusion, is thought to be effective for severely degenerated vertebrae because screws are primarily stabilized at the posterior elements. We evaluated the efficacy of this approach through in vivo insertional torque measurement. OVERVIEW OF LITERATURE There has been only one prior in vivo study on CBT insertional torque. METHODS Between January 2013 and April 2014, a total of 22 patients underwent posterior lumbar fusion using the CBT technique. The maximum insertional torque, which covers the radial strength needed for insertion, was measured for 113 screws, 8 of which were inserted for L5 spondylolysis. The insertional torque for cases with (n=8) and without (n=31) spondylolysis of L5 were compared using one-way analysis of variance (ANOVA). To evaluate vertebral degeneration, we classified 53 vertebrae without spondylolysis by lumbar radiography using semiquantitative methods; the insertional torque for the 105 screws used was compared on the basis of this classification. Additionally, differences in insertional torque among cases grouped by age, sex, and lumbar level were evaluated for these 105 screws using ANOVA and the Tukey test. RESULTS The mean insertional torque was significantly lower for patients with spondylolysis than for those without spondylolysis (4.25 vs. 8.24 in-lb). There were no statistical differences in insertional torque according to vertebral grading or level. The only significant difference in insertional torque between age and sex groups was in men <75 years and women ≥75 years (10 vs. 5.5 in-lb). CONCLUSIONS Although CBT should be used with great caution in patient with lysis who are ≥75 years, it is well suited for dealing with severely degenerated vertebrae because the pars interarticularis plays a very important role in the implementation of this technique.

Abstract
BACKGROUND Vertebral fractures are the most common type of osteoporotic fracture among women, but estimates of their prevalence and incidence during middle-age are limited. The development of vertebral morphometry (VM) using dual energy X-ray absorptiometry (DXA) makes it more feasible to measure VM in large, longitudinal, observational studies. We conducted this study to: 1) contribute to the scant knowledge of the prevalence, incidence and risk factors for vertebral deformities in middle-aged women; and 2) to evaluate the performance of DXA-based VM measurement in a large, community based sample. METHODS The sample is derived from the Study of Women's Health Across the Nation (SWAN), a multi-site, community-based, longitudinal cohort study of the MT. Using Hologic QDR 4500A instruments, we acquired initial VM measurements in 1446 women during calendar years 2004-2007; in 2012-2013, a follow-up VM was obtained in 1108. Annually, lumbar spine (LS) and femoral neck (FN) bone mineral density (BMD) were measured and participant characteristics were assessed with standardized instruments. Multivariable logistic regression models examined the relations between prevalent deformity and relevant characteristics. Analyses of characteristics associated with prevalent deformity were restricted to 824 women who had not taken bone active medications since SWAN baseline. We calculated incident deformity per person year (PY) of observation, standardized to 1000 person-years. RESULTS The cranial portion of the VM image yielded the lowest proportions of readable vertebrae: from T4 through T6, between 43% and 63% of vertebral bodies were evaluable. Greater BMI was associated with fewer readable levels (B = -0.088, p<0.0001). In the baseline sample of 1446 women, the prevalence of vertebral deformity was 3.2% (95% CI: 2.3, 4.1). The relative odds of deformity increased by 61% per SD decrement in baseline LS BMD (p = 0.02) and were 67% greater per SD decrement in baseline FN BMD (p = 0.04). Odds of prevalent deformity increased by 21% per year increment in age (p = 0.02). On average, 1108 women were followed for 6.8 years (SD 0.5 years, range 5.1-8.3 years) and we observed an incidence of 1.98 vertebral deformities per 1000 PY. In the longitudinal sample, 628 participants had never used bone active medications; their vertebral deformity incidence was 2.8 per 1000 PY. CONCLUSION Prevalence of vertebral deformity in SWAN participants aged 50-60 years was low and lower bone density at the LS and FN was strongly related to greater risk of prevalent deformity. Only about half of the vertebral levels between T4-T6 could be adequately imaged by DXA. Greater BMI is associated with fewer readable vertebral levels.

Abstract
The aim of this study was to investigate if differences in leg positioning affect spinal bone mineral density (BMD) measurements and the detection of low bone mass. Subjects included 1039 Japanese patients, 878 women and 161 men (mean ages: 67 and 71 years, respectively). Spinal BMD (L1-4) was measured using dual-energy X-ray absorptiometry (DXA) with patients lying in 2 different positions: (1) supine on the scanning table with hips flexed and knees flexed over a 90° support pad (the standard position) and (2) simply supine (the supine position). Predictive indices were calculated for spinal DXA acquired with patients in the supine position. A BMD T-score of -2.5 or lower was set as the threshold for low bone mass. For the standard and the supine positions during scanning in women, BMDs were 0.911 and 0.915 g/cm(2), respectively; in men, they were 1.117 and 1.124 g/cm(2), respectively. The estimated systematic bias in BMD between the positions was 0.42% (95% confidence interval: 0.24, 0.59; p = 0.009). Random errors in the densitometry measurements for the standard and supine positions were 0.66% and 0.84%, respectively. There was no significant difference between the errors (p= 0.164). The likelihood ratios of a positive and negative test for the detection of low bone mass following supine DXA were 121.0 and 0.066, respectively, compared with results acquired using the standard position. In conclusion, DXA measurements acquired with patients in the supine position slightly overestimated BMD vs the standard position. However, the clinical equivalency between the positioning methods for DXA is preserved to the extent that low bone mass can be reliably detected in the supine position.

Risk factors for vertebral compression fractures in preoperative chemoradiotherapy with gemcitabine for pancreatic cancer. Radiother Oncol 2016; 118:424-9. [PMID: 26806264 DOI: 10.1016/j.radonc.2016.01.006] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2015] [Revised: 01/05/2016] [Accepted: 01/10/2016] [Indexed: 10/22/2022]
Abstract
BACKGROUND AND PURPOSE Preoperative chemoradiotherapy (CRT) with gemcitabine (GEM) for pancreatic cancer is often accompanied by vertebral compression fractures (VCFs). This study aimed to establish the incidence of VCFs and identify the related risk factors (RFs) to elucidate how to decrease the overall incidence of VCF. MATERIAL AND METHODS We investigated 220 patients with resectable or borderline-resectable pancreatic cancers who had completed preoperative CRT between 2006 and 2011. The RFs associated with VCF were analyzed in a total of 1308 thoracolumbar vertebral bodies. RESULTS Thirty-seven VCFs occurred in 25 patients (11%); the cumulative incidence at two years was 18.9%. Univariate analysis revealed female sex, age and high daily GEM concentration during radiotherapy as RFs for VCF. The multivariate mixed effects logistic regression model demonstrated that the most responsible factor was radiation dose (p<0.001). We estimated the radiation condition resulting in a fracture incidence of ⩽5% by counting the patient's number of the three RFs. For patients with three factors, the mean vertebral dose was 22.0 Gy. CONCLUSIONS The RFs for VCF after CRT were identified. The side effect of VCF might be avoided by regulating the radiation dose to neighboring vertebral bodies after considering the RFs.

Abstract
Vertebral fractures are one of the most common fractures associated with skeletal fragility and can cause as much morbidity as hip fractures. However, the epidemiology of vertebral fractures differs from that of osteoporotic fractures at other skeletal sites in important ways, largely because only one quarter to one-third of vertebral fractures are recognized clinically at the time of their occurrence and otherwise require lateral spine imaging to be recognized. This article first reviews the prevalence and incidence of clinical and radiographic vertebral fractures in populations across the globe and secular trends in the incidence of vertebral fracture over time. Next, associations of vertebral fractures with measures of bone mineral density and bone microarchitecture are reviewed followed by associations of vertebral fracture with various textural measures of trabecular bone, including trabecular bone score. Finally, the article reviews clinical risk factors for vertebral fracture and the association of vertebral fractures with morbidity, mortality, and other subsequent adverse health outcomes.

Abstract
Despite experimental and animal evidence showing the detrimental effects of platelet-activating factor (PAF) on bone metabolism, there are no clinical studies relating PAF to osteoporosis-related phenotypes. This case-control study investigates the association between plasma PAF, osteoporotic vertebral fracture (VF), and bone mineral density (BMD) in postmenopausal Korean women. Among 474 eligible women not taking any drug or having any disease that could affect bone metabolism, we identified 73 cases defined as subjects with radiological VF. The controls were randomly selected from the remaining 401 subjects and matched 1:1 to cases in terms of both age and body mass index (BMI). Lateral thoracolumbar radiographs, BMD, and plasma PAF levels were determined for all subjects. Postmenopausal women with VF demonstrated 34.6 % higher plasma PAF levels than subjects without VF after adjusting for age, BMI, smoking habits, alcohol intake, regular exercise, and parental history of osteoporotic fractures (P = 0.021). Multiple logistic regression analyses revealed that the odds ratio for VF linearly increased across increasing PAF quartiles (P for trend = 0.040) and the odds for VF were 2.88-fold higher in subjects in the highest quartile in comparison with those in the lowest quartile (95 % CI 1.04-8.01). Plasma PAF levels were inversely correlated with BMD at various sites (γ = -0.253 to -0.176, P = 0.003-0.041). These findings suggest that plasma PAF may be a potential biomarker for predicting poor bone health in postmenopausal women.

Abstract
Loss of bone and muscle with advancing age represent a huge threat to loss of independence in later life. Osteoporosis represents a major public health problem through its association with fragility fractures, primarily of the hip, spine and distal forearm. Sarcopenia, the age related loss of muscle mass and function, may add to fracture risk by increasing falls risk. In the context of muscle aging, it is important to remember that it is not just a decline in muscle mass which contributes to the deterioration of muscle function. Other factors underpinning muscle quality come into play, including muscle composition, aerobic capacity and metabolism, fatty infiltration, insulin resistance, fibrosis and neural activation. Genetic, developmental, endocrine and lifestyle factors, such as physical activity, smoking and poor diet have dual effects on both muscle and bone mass in later life and these will be reviewed here. Recent work has highlighted a possible role for the early environment. Inflammaging is an exciting emerging research field that is likely to prove relevant to future work, including interventions designed to retard to reverse bone and muscle loss with age.

Age-related normative values of trabecular bone score (TBS) for Japanese women: the Japanese Population-based Osteoporosis (JPOS) study. Osteoporos Int 2015; 26:245-52.

Abstract
UNLABELLED Trabecular bone score (TBS), a surrogate measure of bone microarchitecture, represents fracture risk independently of bone density. We present normative TBS values from a representative population study of Japanese women. This database would enhance our understanding of trabecular bone microarchitecture and improve osteoporosis management. INTRODUCTION TBS is a texture parameter that quantifies local variation in gray level distribution within dual-energy X-ray absorptiometry (DXA) images of the lumbar spine. While TBS is associated with fracture risk independently of areal bone mineral density (aBMD), normative TBS values have only been reported for Caucasian women. This study provides age-specific normative values of TBS from a representative sample of Japanese women. METHODS We randomly selected 4,550 women aged 15-79 years from 7 areas throughout Japan. Women younger than 20 years and those with any medical history which might affect bone metabolism were excluded, and the remaining 3,069 with at least two assessable vertebrae from the first to the fourth vertebrae were subjected to analysis. TBS values were calculated from spine DXA images using TBS iNsight software (Med-Imaps, France). Age-related models of TBS were constructed using piecewise linear regression analysis. RESULTS Participant age, body mass index (BMI), spine aBMD, and TBS (mean ± SD) were 48.7 ± 16.8 years, 22.9 ± 3.4, 0.888 ± 0.169 g/cm(2), and 1.187 ± 0.137, respectively. A three-piece linear regression model of TBS on age explained 70.7% of the total variance in TBS and comprised very small age-related changes in the youngest segment of the regression line, rapid loss in the middle segment, and small loss in the oldest segment. TBS was lower in Japanese women than in Caucasian women across all age ranges, with the difference increasing with age up through 65 years. CONCLUSIONS The normative values of TBS for Japanese women presented here would enhance our understanding of trabecular bone microarchitecture and help improve the management of osteoporosis.

Abstract
Purpose To systematically review the literature describing the efficacy, effectiveness, and safety of raloxifene for postmenopausal Japanese women with osteoporosis or low bone mass (osteopenia). Materials and methods Medline via PubMed and Embase was systematically searched using prespecified terms. Retrieved publications were screened and included if they described randomized controlled trials or observational studies of postmenopausal Japanese women with osteoporosis or osteopenia treated with raloxifene and reported one or more outcome measures (change in bone mineral density [BMD]; fracture incidence; change in bone-turnover markers, hip structural geometry, or blood–lipid profile; occurrence of adverse events; and change in quality of life or pain). Excluded publications were case studies, editorials, letters to the editor, narrative reviews, or publications from non-peer-reviewed journals; multidrug, multicountry, or multidisease studies with no drug-, country-, or disease-level analysis; or studies of participants on dialysis. Results Of the 292 publications retrieved, 15 publications (seven randomized controlled trials, eight observational studies) were included for review. Overall findings were statistically significant increases in BMD of the lumbar spine (nine publications), but not the hip region (eight publications), a low incidence of vertebral fracture (three publications), decreases in markers of bone turnover (eleven publications), improved hip structural geometry (two publications), improved blood–lipid profiles (five publications), a low incidence of hot flushes, leg cramps, venous thromboembolism, and stroke (12 publications), and improved quality of life and pain relief (one publication). Conclusion Findings support raloxifene for reducing vertebral fracture risk by improving BMD and reducing bone turnover in postmenopausal Japanese women with osteoporosis or osteopenia. Careful consideration of fracture risk and the risk–benefit profile of antiosteoporosis medications is required when managing patients with osteoporosis.
