  • The effect of a multidisciplinary co-management program for the older hip
           fracture patients in Beijing: a “pre- and post-” retrospective study
    • Abstract: Summary Hip fracture becomes a major public health issue with the growing aging population. This study evaluated a multidisciplinary co-management program for older hip fracture patients and found it significantly improved the best practice indicators. It provided preliminary evidence to support the use of such intervention in hip fracture management. Purpose/introduction Hip fracture leads to high morbidity and mortality in older people. A previous study found a significant disparity in hip fracture management in Beijing Jishuitan Hospital (JSTH) compared to best practice care in the United Kingdom (UK). Following this audit, JSTH launched a multidisciplinary co-management care plan for older hip fracture patients. This study aims to evaluate the effect of this program on the six standards recommended in the UK hip fracture best practice guidelines. Methods In this retrospective study, electronic medical record data were collected before and after the intervention. Eligible patients were aged ≥ 65 years, had X-ray confirmed hip fracture, and were admitted to JSTH within 30 days of injury. Patient demographic information, time from emergency department presentation to admission, time from admission to surgery, pressure ulcers, osteoporosis assessment, and falls prevention were collected. Multivariable logistic and median regression models were used for binary and continuous outcomes respectively. Segment regression was also performed for time-related outcomes. Results A total of 3540 eligible patients were identified. After the intervention, half of the patients who received co-management received surgery within 48 h of ward admission compared to 6.4% previously, 0.3% (vs 1.4%) developed pressure ulcers, and 76% (vs 19%) received osteoporosis assessment. No significant differences were observed in fall assessment rates. However, there was a higher rate of ward admission within 4 h of arrival in emergency for patients admitted pre-intervention (61% vs 34%). Conclusions The introduction of the co-management model significantly reduced the time from admission to surgery and improved other practice outcomes. A multicenter randomized controlled trial is needed to evaluate the impact of this model on patient health outcomes.

  • Adherence to bisphosphonates in the general population: a study in
           patients referred to a primary care service
    • Abstract: Purpose The aim of the study was to evaluate the adherence to treatment with bisphosphonates in women with postmenopausal osteoporosis referred to a primary care clinic. Methods A total of 7257 outpatients were referred to the primary care service where the study was conducted. We retrieved data of postmenopausal women to which bisphosphonates have been prescribed in the period January 1, 2000–December 31, 2014, and analyzed the group of patients who had discontinued the drug. Results The total number of women treated with bisphosphonates was 285 (mean age 72 ± 9.8 years). At the time the data were retrieved, 157 (55% of the total) had discontinued therapy. Among them, 119 (41.7%) agreed to participate in the study. They reported the following reasons for treatment discontinuation: withdrawal by another physician (40%), lack of motivation (20%), absence of BMD improvement (14%), uncomfortable way of drug administration (11%), side effects (6%), fear of side effects (1.6%), high number of concomitant medications (0.8%), and others (6.6%). Sixty patients (50.4%) discontinued therapy within 2 years, 27 patients (23%) > 2 and ≤  5 years and 32 (27%) after 5 years. Conclusions Our study demonstrates that more than half of women with postmenopausal osteoporosis referred to a primary care service discontinued bisphosphonates before the clinical effect can be seen and mostly because of advice by physicians not initially prescribing the drug. There is an inappropriate management of bisphosphonate therapy in terms of therapeutic efficacy and strategies aimed at ameliorating clinical management of osteoporosis patients are warranted.

  • Oral bisphosphonate use and the risk of female breast, ovarian, and
           cervical cancer: a nationwide population-based cohort study
    • Abstract: Summary Bisphosphonate use was not associated with the risk of female breast, ovarian, or cervical cancer. The results according to bisphosphonate type or concurrent drug uses were not associated with the cancer risk. The protective effect of bisphosphonate use on female breast cancer was significant in the low comorbidity group. Purpose Despite the antitumor mechanisms, the effect of bisphosphonates on the risk of cancer is still unclear. We investigated the association between oral bisphosphonate use and the development of female breast, ovarian, and cervical cancer. Methods We accomplished a population-based cohort study using the National Health Insurance Services (NHIS) database. A total of 204,525 participants were included in a cohort, and we identified the incident cases of each cancer from 2007 to 2013. We assessed cumulative bisphosphonate exposure from 2003 to 2006 using the defined daily dose (DDD) system. Hazard ratios (HRs) and their 95% confidence intervals (CIs) were presented to assess the association between bisphosphonate use and cancer incidence using multivariate Cox proportional hazard regression models. Subgroup analyses were performed to assess cancer development according to risk factors and concurrent drug use. Results There was a total of 1547, 266, and 370 incident cases of female breast, cervical, and ovarian cancer, respectively, during the study period of 1,367,294 person-years. Bisphosphonate exposure was not significantly associated with risk of female breast (adjusted HR (aHR), 0.78; 95% CI, 0.60–1.02), ovarian (aHR, 1.30; 95% CI, 0.82–2.07), nor cervical cancer (aHR, 0.70; 95% CI, 0.44–1.12). Further subgroup analyses also revealed no statistically significant effects of bisphosphonate use with various risk factors and concurrent drug use. Conclusions Our study showed no significant associations between bisphosphonate exposure and female breast, cervical, and ovarian cancer. In the future, large prospective studies or a meta-analysis would be needed to verify the associations.

  • Predictors of long-term survival after hip fractures'—5-year results
           of a prospective study in Germany
    • Abstract: Summary The incidence of hip fractures is increasing due to demographic transition. Data on long-term survival and influencing factors are sparse. Our prospective observational study with 395 patients shows a survival of 38% after 5 years. Significant risk factors were male gender, higher age, lower Barthel Index, lower Charlson Comorbidity Score, lower Mini-Mental State Examination, and delirium during hospitalization. Purpose The incidence of hip fractures is increasing due to demographic transition. Until now, they are associated with poor results and high mortality rates. Data on long-term survival and influencing factors are sparse. Therefore, a prospective observational study was conducted. Methods Patients ≥ 60 years with hip fracture were included in this prospective study between 2009 and 2011. Demographic parameters, as well as ASA Score, pre-fracture Barthel Index and EQ-5D, Mini-Mental State Examination, Charlson Comorbidity Score, fracture type, type of surgical treatment, place of discharge, and arising complications were registered. Outcome parameter was survival during a 5-year follow-up period. Results A total of 539 patients attended to our emergency room during the period of recruitment. The recruitment rate was 75%. A total of 402 patients were included; 7 were lost to follow-up, and 152 (38%) survived the study period. The mortality was more than 25% in the first year after fracture. Subsequently, it was between 7 and 9% per year. In the multivariate analysis, significant risk factors for dying were male gender (p = 0.002), higher age (p < 0.001), lower Charlson Comorbidity Score (p = 0.033), lower Barthel Index (p = 0.024), lower Mini-Mental State Examination (p = 0.002), and occurrence of delirium during hospitalization (p = 0.008). Conclusion Our results confirm poor results of geriatric patients after hip fracture. While early results might be influenced by optimal fracture care, long-term results seem to be determined by not changeable patient factors. Nevertheless, more than one third of surviving patients after 5 years justify the elaborate treatment algorithms for these fragile patients.

  • The 2018 Guidelines for the diagnosis and treatment of osteoporosis in
           Greece
    • Abstract: Summary We report the updated guidelines for the management of osteoporosis in Greece, which include guidance on fracture risk assessment, diagnosis-pharmacological treatment-follow-up of osteoporosis based on updated information, and national evidence from Greek clinical practice and the healthcare setting. Purpose The purpose of this report was to update the Guidelines for the Management of Osteoporosis in Greece that was published in 2011. Methods In line with the GRADE system, the working group initially defined the main clinical questions that should be addressed when dealing with the diagnosis and management of osteoporosis in clinical practice in Greece. Following a literature review and discussion on the experience gained from the implementation of the 2011 Guidelines transmitted through the national electronic prescription network, the Hellenic Society for the Study of Bone Metabolism (HSSBM) uploaded an initial draft for an open dialogue with the relevant registered medical societies and associations on the electronic platform of the Greek Ministry of Health. After revisions, the Central Health Council approved the final document. Results The 2018 Guidelines provide comprehensive recommendations on the issues of the timing of fracture risk evaluation and dual-energy X-ray absorptiometry (DXA) measurement, interpretation of the DXA results, the diagnostic work-up for osteoporosis, the timing as well as the suggested medications for osteoporosis treatment, and the follow-up methodology employed during osteoporosis treatment. Conclusions These updated guidelines were designed to offer valid guidance on fracture risk assessment, diagnosis-pharmacological treatment-follow-up of osteoporosis based on updated information and national evidence from clinical practice and the healthcare setting. Clinical judgment is essential in the management of every individual patient for the purpose of achieving the optimal outcome in the safest possible way.

  • Stages of sarcopenia, bone mineral density, and the prevalence of
           osteoporosis in older women
    • Abstract: Summary A better understanding of the relationship between osteoporosis and sarcopenia may help to develop effective preventive and therapeutic strategies. In the present study, the association between different stages of sarcopenia, BMD, and osteoporosis was examined. The salient findings indicate that a dose–response relationship exists between sarcopenia stages and bone-related phenotypes. Purpose To assess the association between sarcopenia stages, bone mineral density (BMD), and the prevalence of osteoporosis in older women. Methods Two hundred thirty-four women (68.3 ± 6.3 years) underwent body composition and BMD measurements using dual-energy X-ray absorptiometry. Quadriceps isokinetic torque was evaluated, and the timed up-and-go test was conducted as a measure of function. Sarcopenia stages were classified according to European Working Group on Sarcopenia in Older People (EWGSOP): nonsarcopenia, presarcopenia, sarcopenia, and severe sarcopenia. Osteoporosis was defined as BMD value (hip or spine) 2.5 standard deviations below a young-adult reference population. Between-group differences were examined using ANOVA for continuous variables and chi-squared for categorical variables. Logistic regression was performed to evaluate the association between sarcopenia stages and osteoporosis. Results Rates of osteoporosis were 15.8%, 19.2%, 35.3%, and 46.2% for nonsarcopenia, presarcopenia, sarcopenia, and severe sarcopenia, respectively (P = 0.002). Whole-body and femoral neck BMD values were significantly lower among all sarcopenia stages when compared to nonsarcopenia (all P values < 0.05, η2p 0.113 to 0.109). The severe sarcopenia group also showed significantly lower lumbar spine BMD values and T-scores (both P values < 0.05; η2p 0.035 and 0.037, respectively). When clustered, sarcopenia and severe sarcopenia exhibited lower BMD values for all sites (all P values < 0.01), and presented a significantly higher risk for osteoporosis (odds ratio 3.445; 95% CI 1.521–7.844). Conclusion The observed results provide support for the concept that a dose–response relationship exists between sarcopenia stages, BMD, and the presence of osteoporosis. These findings strengthen the clinical significance of the EWGSOP sarcopenia definition and indicate that severe sarcopenia should be viewed with attention by healthcare professionals.

  • Epidemiological and clinical study of hip fracture in hospitalized elderly
           patients in Shanghai, China
    • Abstract: Summary In this study, we attempted to determine the epidemiology and clinical characteristics of hip fracture in the elderly. We find that elderly people with hip fracture have multiple comorbidities and suffer numerous complications. Introduction We attempted to explore the epidemiology and clinical characteristics of hip fracture in the elderly. Methods One thousand five hundred thirty-nine patients aged over 65 years were included in the retrospective study. From the medical records, information was gathered about pre-fracture conditions, as well as fracture type, surgical details, laboratory indicators, postoperative complications, length of stay, outcomes, and costs of hospitalization. Binary logistic regression was used to screen for potential risk factors for perioperative complications and postoperative death, and general linear models were used to determine factors that influenced the cost of surgical treatment. Results The average age of hip fracture patients in our study was 82.20 ± 6.82 years old, and the male-to-female ratio was 1:2.82. In 1356 patients who underwent hip surgery, the incidence of perioperative complications was 6.71% (91/1356), and the postoperative mortality rate was 1.11% (15/1356). Factors associated with perioperative complications were male sex, heart function class III or higher, serum albumin < 35 g/L, respiratory diseases, and perioperative blood transfusion (P < 0.05). Perioperative blood transfusion was an independent risk factor for postoperative death after hip fracture in the elderly (P < 0.05). The main factors that influenced hospitalization expenses related to elderly hip fracture patients were type of surgery, method of anesthesia, length of stay, perioperative complications, and outcomes (P < 0.05). Conclusions Elderly people with hip fracture have multiple comorbidities and suffer numerous complications. Thus, randomized intervention studies should focus on prevention of complications that might be avoidable.

  • Revised FRAX®-based intervention thresholds for the management of
           osteoporosis among postmenopausal women in Sri Lanka
    • Abstract: Summary This paper revised the fixed intervention thresholds (ITs) based on the Sri Lankan fracture risk assessment tool (FRAX) published in 2013 and introduced new ITs, hybrid and two-tier, aiming to help clinicians in the management of postmenopausal osteoporosis. The hybrid and two-tier ITs have a better discriminatory power than age-dependent and revised fixed ITs. Introduction This study revised the Sri Lankan FRAX®-based intervention thresholds (ITs) previously published in 2013. Method Age-dependent ITs were estimated, from 50–80 years with 5-year intervals, using a Sri Lankan FRAX® algorithm for a woman with a BMI of 24.8 kg/m2 and history of prior fragility fracture without other clinical risk factors. Data of 653 postmenopausal women were used in estimating fixed, hybrid, and two-tier ITs. ITs were determined using the ROC curve and partial Youden index. New ITs were validated using data of 356 postmenopausal women who underwent DXA and 62 women who had a recent fragility fracture. Women in the two groups (n = 653 and n = 356) came from the Southern Province and had undergone DXA in our state-owned tertiary care hospital as a part of their routine clinical assessment. Results The mean (SD) age and BMI of the subjects (n = 653) were 62 (8) years and 24.8 (1.2) kg/m2, respectively. Age-dependent ITs of major osteoporotic fracture risk (MOFR) and hip fracture risk (HFR) ranged from 2.7 to 18% and from 0.4 to 7.1%. The best fixed ITs for women aged 50–80 years were 9% for MOFR and 3% for HFR. In the hybrid method, MOFR of 6% and HFR of 2% were found appropriate for women aged < 70 years. These were combined with age-dependent ITs for women aged 70 years and above. In the two-tier system, two sets of ITs were calculated (ITs of MOFR/HFR for women aged < 70 years and ≥ 70 years were 6%/2% and 12%/5%, respectively). When age-dependent ITs were considered the reference standard, sensitivities of the fixed, hybrid, and two-tier ITs were 0.63, 0.73, and 0.74, respectively. The specificities were 0.76, 0.86, and 0.80 in the same order. Sensitivities of the age-dependent, fixed, hybrid, and two-tier ITs in identifying a woman with an incident fracture were 26%, 48%, 61%, and 61%, respectively. Conclusions The new fixed MOFR is slightly lower than the previous value and hybrid and two-tier ITs perform better than age-dependent and fixed ITs.

  • Association between serum high-density lipoprotein cholesterol and bone
           health in the general population: a large and multicenter study
    • Abstract: Summary This study was a cross-sectional study and enrolled 14,147 participants after excluding. We performed a large number of data analyses to indicate that HDL-C levels were related to bone health. A high HDL-C level is an independent risk factor for bone loss both in males and females. Introduction Serum high-density lipoprotein cholesterol (HDL-C), usually called “good” cholesterol, is beneficial for preventing cardiovascular diseases. Previous studies have indicated that HDL-C levels may be related to bone mass. We performed a cross-sectional study to examine the relationship between HDL-C levels and bone mass, both in men and women. Methods A total of 14,147 Chinese participants from five medical centers were enrolled in this study. Pearson’s correlation analyses, linear regression analyses, one-way ANOVAs, and logistic regression analyses were performed to assess the relationship between HDL-C levels and bone mass in various cohorts. Results Binary logistic regression analyses (after adjusting the confounding factors) indicated that a higher HDL-C level among males leads to a higher risk of at least osteopenia [OR (95% CI) = 1.807 (1.525, 2.142)] and osteoporosis [OR (95% CI) = 1.932 (1.291, 2.892)]. In the female group, the ORs of HDL-C for at least osteopenia [OR (95% CI) = 1.390 (1.100, 1.757)] and osteoporosis [OR (95% CI) = 1.768 (1.221, 2.560)] were still significant after adjusting for potential confounding factors except BMI. Data-standardized bivariate logistic regression analyses indicated that an increase in age is a stronger risk factor for osteoporosis and at least osteopenia than is higher HDL-C levels in females. Conclusions A high HDL-C level is an independent risk factor for bone loss both in males and females. Compared with high HDL-C levels, an increase in age and menopause have a much more negative effect on bone mass in females.

  • The association between hepatitis and osteoporosis: a nested case-control
           study using a national sample cohort
    • Abstract: Summary The prevalence of hepatitis B was higher in osteoporosis patients than the control group, especially in females. However, the prevalence of hepatitis C was not different. The matching for various factors improved to have same conditions between osteoporosis patients and the control group. Purpose Although chronic liver disease, including hepatitis B and hepatitis C, has been associated with osteoporosis in previous studies, the evidence was insufficient, and some findings were inconsistent. The aim of this study was to evaluate the relationship between hepatitis B or hepatitis C and osteoporosis. Methods We used the Korean National Health Insurance Service-National Sample Cohort with ≥ 50-year-old participants from 2002 to 2013. Age was determined at osteoporosis diagnosis. We extracted 68,492 osteoporosis patients (ICD-10 codes E7001–E7004, HC341–HC345) with a 68,492-member control group at a ratio of 1:1 by age, sex, income, region of residence, hypertension, diabetes, and dyslipidemia. We analyzed previous histories of hepatitis B (ICD-10 codes B18.0–B18.1) and hepatitis C (ICD-10 code B18.2) in the osteoporosis patients and control groups. The logistic regression with the crude and adjusted model was analyzed. Additionally, subgroup analyses divided by age and sex were performed. Results The adjusted odds ratios for hepatitis B and hepatitis C were 1.19 (95% confidence interval (CI) = 1.11–1.28, P < 0.001) and 1.04 (95% CI = 0.90–1.19, P > 0.05), respectively, in osteoporosis patients. Subgroup analyses showed that the risk of hepatitis B was higher in osteoporosis patients in female groups but not in male groups. Conclusion Hepatitis B virus infection might be a risk factor for osteoporosis.

  • Effects of denosumab on bone metabolism and bone mineral density in kidney
           transplant patients: a systematic review and meta-analysis
    • Abstract: Objective The use of immunosuppressive agents, especially glucocorticoids, are associated with increased risks of bone loss in kidney transplant patients. Denosumab, a potent antiresorptive agent, has been shown to increase bone mineral density (BMD) in patients with CKD. However, its effects on bone metabolism and BMD in kidney transplant patients remain unclear. Methods A literature search was conducted using MEDLINE, EMBASE, and Cochrane Database from inception through April 2018 to identify studies evaluating denosumab’s effect on changes in bone metabolism and BMD from baseline to post-treatment course in kidney transplant patients. Study results were pooled and analyzed utilizing random-effects model. The protocol for this systematic review is registered with PROSPERO (International Prospective Register of Systematic Reviews; no. CRD42018095055). Results Five studies (a clinical trial and four cohort studies) with a total of 162 kidney transplant patients were identified. The majority of patients had a baseline eGFR ≥ 30 mL/min/1.73 m2. After treatment (≥ 6 to 12 months), there were significant increases in BMD with standardized mean differences (SMDs) of 3.26 (95% CI 0.88–5.64) and 1.83 (95% CI 0.43 to 3.22) for lumbar spine and femoral neck, respectively. There were also significant increases in T scores with SMDs of 0.92 (95% CI 0.58 to 1.25) and 1.14 (95% CI 0.17 to 2.10) for lumbar spine and femoral neck, respectively. After treatment, there were no significant changes in serum calcium (Ca) or parathyroid hormone (PTH) from baseline to post-treatment course (≥ 6 months) with mean differences (MDs) of 0.52 (95% CI, − 0.13 to 1.16) mmol/L and − 13.24 (95% CI, − 43.85 to 17.37) ng/L, respectively. The clinical trial data demonstrated more asymptomatic hypocalcemia in the denosumab (12 episodes in 39 patients) than in the control (1 episode in 42 patients) group. From the cohort studies, the pooled incidence of hypocalcemia following denosumab treatment was 1.7% (95% CI 0.4 to 6.6%). All reported hypocalcemic episodes were mild and asymptomatic, but the majority of patients required Ca and vitamin D supplements. Conclusion Among kidney transplant patients with good allograft function, denosumab effectively increases BMD and T scores in the lumbar spine and femur neck. From baseline to post-treatment, there are no differences in serum Ca and PTH. However, mild hypocalcemia can occur following denosumab treatment, requiring monitoring and titration of Ca and vitamin D supplements.

  • The epidemiology of osteoporosis, associated fragility fractures, and
           management gap in China
    • Abstract: Background Osteoporosis has been one of the most common but largely under-diagnosed clinical problems among elderly population. The disease burden is even greater in China because of limited medical resources and large population size. This article is aimed to provide an overview of disease burden, secular trend, and management gap of osteoporosis and related fractures in China. Methods Based on the related studies published in English and Chinese from 1990 to 2017, we investigated the prevalence/incidence of osteoporosis and osteoporotic fracture in Chinese mainland, Hong Kong, and Taiwan, characterizing the secular trend and disease burden in different regions. Strict inclusion criteria were applied to control the study quality. We further examined the diagnosis and treatment gap of osteoporosis management observed in clinical practice in China and summarized the efforts made by Chinese government and scholars to combat this situation. Results Twenty-seven studies concerning osteoporosis prevalence in China (including Chinese mainland, Hong Kong, and Taiwan) met the inclusion criteria and were included in the final analysis. Another 15 studies about hip fracture incidence and 13 studies about vertebral fracture prevalence/incidence were also included. The epidemiological data varied greatly across studies due to different design and population included. A higher prevalence was indicated in female population, older age groups, and residents in northern China compared to their counterparts. Though attenuated increased rates or slight decline patterns have been observed in Hong Kong and Taiwan, osteoporotic fracture incidence still showed steady increase in Chinese mainland. The diagnosis and treatment of osteoporosis as well as post-fracture management were still insufficient in China. Conclusion Due to its silent nature, osteoporosis and its related fractures remain largely under-diagnosed and under-managed in China. It also highlights the scarcity of high-quality studies specifically focus on longtime documentation of disease burden change and male population, especially in mainland area.

  • Body compositions differently contribute to BMD in different age and
           gender: a pilot study by QCT
    • Abstract: Summary The study was to investigate the correlation between body compositions and bone mineral density (BMD) and to evaluate the body composition contribution to BMD. In male, LM showed positive effect on BMD. In female, SAT showed positive, and FM and F/L showed negative effect on BMD. Purpose The purpose of the study was to investigate the correlation between body compositions and bone mineral density (BMD) performed by quantitative computed tomography (QCT), and to evaluate the body composition contribution to BMD. Methods Three hundred ninety-four participants, including 122 male (31%) and 272 female (69%), were divided into groups by gender, age, and BMD. BMD and body compositions [including fat mass (FM), lean mass (LM), bone mass/lean mass ratio (B/L), fat mass/lean mass ratio (F/L), total adipose tissue (TAT), subcutaneous adipose tissue (SAT), visceral adipose tissue (VAT)] were retrospectively compared among groups using one-way ANOVA or t test. A stepwise multivariate analysis was used to evaluate the body composition contribution to BMD and produced models. Results In male, BMD got decreased with age (P < 0.05). LM increased before 30–49 years, then decreased (P < 0.05). TAT and SAT decreased with age (P < 0.05). LM in OP group was lower than those in the other two groups (P < 0.05). Through stepwise multivariate analysis, LM firstly got into model 1 (M1, β = 0.589). In female, BMD, LM TAT, and VAT were increased before 30–49 years, then decreased (P < 0.05). FM and F/L increased with age (P < 0.05). SAT decreased with age (P < 0.05). FM and F/L in OP group were higher than those in other groups. LM, B/L, TAT, and SAT in the OP group were lower than those in the other groups (P < 0.05). SAT entered the M1 with a maximum β value (β = 0.584). Conclusions BMD and body compositions displayed different characteristics with age. In male, LM showed positive effect on BMD. In female, SAT showed positive, and FM and F/L showed negative effect on BMD.

  • Celiac disease and severe vitamin D deficiency: the case for anti-tissue
           transglutaminase antibody screening
    • Abstract: Summary Vitamin D-deficient Saudi adolescent girls were screened for anti-tissue transglutaminase (IgA-tTG) antibodies to determine whether the presence of severe vitamin D deficiency was associated with celiac disease. All 9 participants who were positive for IgA-tTG antibodies had severe vitamin D deficiency (25(OH)D < 12.5 nmol/l), suggesting that this population should be screened for celiac disease. Purpose The current cross-sectional study aimed to see if severe vitamin D deficiency is associated with celiac disease (CD) among Saudi adolescent girls. Methods A total 200 adolescent females aged 13–19 years old with vitamin D deficiency (serum 25(OH)D < 50 nmol/l) were screened for IgA tTG (anti-tissue transglutaminase antibodies). Results Of the 200 girls, 9 (4.5%) were positive for IgA tTG antibodies; all of whom had serum 25(OH)D < 12.5 nmol/l. A strong significant inverse association was observed between tTG antibody levels and serum 25(OH)D (R = − 0.53; p < 0.001) among antibody negative participants. Finally, participants with positive IgA tTG antibodies was 37.2 times higher for participants with 25(OH)D < 12.5 nmol/l than those whose vitamin D status was higher [OR = 37.2 (95% CI 4.6–299.7) (p = 0.0002)]. Conclusion The data suggests that CD maybe a risk factor for severe vitamin D deficiency and that patients presenting with very low levels of 25(OH)D of less than 12.5 nmol/l—in the absence of an obvious cause—may need to be screened for CD.

  • Physical activity as measured by accelerometer in NHANES 2005–2006 is
           associated with better bone density and trabecular bone score in older
           adults
    • Abstract: Summary In an analysis of NHANES 2005–2006, older, but not younger, women and men with higher levels of physical activity had higher TBS, total hip T-score, and femoral neck T-score. Even modest levels of physical activity may be a crucial component of bone health maintenance. Purpose Physical activity is associated with improved bone parameters in adolescence, but it is not clear if this persists into adulthood. Further, it is unclear how low levels of physical activity as measured by accelerometer may impact bone parameters. Methods We analyzed data from subjects from NHANES 2005–2006 over the age of 20 who had accelerometry and bone mineral density (BMD) testing. We analyzed women and men separately and grouped by over or under 50 years of age: 484 younger women, 486 older women, 604 younger men, and 609 older men. Moderate-to-vigorous physical activity (MVPA) was categorized as low (less than 5 min daily), intermediate (5–20 min daily), or high (at least 20 min daily). Results Among younger women and men, there was no significant relationship between MVPA and BMD or trabecular bone score (TBS). Conversely, older women with intermediate and high MVPA had higher TBS (1.360 ± 0.008 and 1.377 ± 0.009 vs 1.298 ± 0.010, p < 0.001), total hip T-score (− 1.02 ± 0.13 and − 0.90 ± 0.09 vs. − 1.51 ± 0.08, p < 0.01), and femoral neck T-score than women with low MVPA, respectively. Similarly, older men with high MVPA had higher TBS, total hip T-score, and femoral neck T-score than men with intermediate and low MVPA. Conclusions Older, but not younger, women and men with higher levels of activity had higher BMD and TBS. Benefits were noted with as little as 5–20 min of daily physical activity. Our results suggest that physical activity is a crucial component of bone health maintenance.

  • The Dutch Hip Fracture Audit: evaluation of the quality of
           multidisciplinary hip fracture care in the Netherlands
    • Abstract: Summary The nationwide Dutch Hip Fracture Audit (DHFA) is initiated to improve the quality of hip fracture care by providing insight into the actual quality of hip fracture care in daily practice. The baseline results demonstrate variance in practice, providing potential starting points to improve the quality of care. Purpose The aim of this study is to describe the development and initiation of the DHFA. The secondary aim is to describe the hip fracture care in the Netherlands at the start of the audit and to assess whether there are differences in processes at baseline between hospitals. Methods Eighty-one hospitals were asked to register their consecutive hip fracture patients since April 2016. In 2017, the first full calendar year, the case ascertainment was determined at audit level. Three quality indicators were used to describe and assess the care process at audit and hospital level: the proportion of completed variables at discharge and at 3 months after operation, time to surgery and orthogeriatric management. Results Sixty (74%) hospitals documented 14,274 patients in the DHFA by December 2017. In 2017, the case ascertainment was 58% and the average proportion of completed variables was 77%: 91% at discharge and 30% at 3 months. The median time to operation was 18 h (IQR 7–23) for American Society of Anesthesiologists score (ASA) 1–2 patients and 21 h (IQR 13–27) for ASA 3–4 patients. Of patients aged 70 years and older, 78% received orthogeriatric management. At hospital level, all three indicators showed significant practice variance. Conclusion Not all hospitals participate in the DHFA, and the data gathering process needs to be further optimized. However, the baseline results demonstrate an apparent variance in hip fracture practice between hospitals in the Netherlands, providing potential starting points to improve the quality of hip fracture care.

  • Exploring the association between number, severity, location of fracture,
           and occiput-to-wall distance
    • Abstract: Summary This study of women with a suspected vertebral fracture determined the association between vertebral fracture characteristics and posture. The number of fractures was associated with posture. Severity of fracture was associated with posture when adjusting for pain. Fracture characteristics explain some variability in posture in women with a suspected vertebral fracture. Purpose Osteoporotic vertebral fractures are associated with increased morbidity and mortality. An accumulation of vertebral fractures may lead to forward head posture, which has been independently associated with mortality. It is unclear how fracture characteristics, including the number, severity, and location of fracture, contribute to occiput-to-wall distance (OWD). Methods This was a cross-sectional secondary data analysis using baseline data from a randomized controlled trial, in community-dwelling women aged 65 years and older with a suspected vertebral fragility fracture. Lateral thoracic and lumbar spine radiographs were used to determine the number, location, and severity of fracture. Occiput-to-wall distance (OWD) was used to assess forward head posture. Pain during movement (0–10 scale) and age were considered as confounding variables. Multivariable regression models were used to evaluate relationships between fracture variables and OWD. Results Participants (n = 158) were of mean age 75.9 (SD 6.5) years with a mean (SD) BMI = 26.7 (5.3) kg/m2, OWD = 5.7 (4.6) cm, and number of fractures = 2.4 (2.4). In unadjusted analyses, the number of fractures (B = 0.82, 95% CI = 0.04, 1.59) was associated with OWD. When adjusting for pain, severity of fractures (B = 1.08, 95% CI = 0.001, 2.15) was independently associated with OWD. Location was not associated with OWD in any of the models. Conclusions The number of fractures was significantly associated with OWD in the unadjusted model, explaining more of the variability in OWD than other fracture characteristics. Severity of fracture was associated with OWD in the adjusted model. However, pain may confound the relationship between OWD and fracture characteristics.

  • Bone age as a correction factor for the analysis of trabecular bone score
           (TBS) in children
    • Abstract: Summary Trabecular bone score (TBS) is a tool to improve evaluation of DXA scans, barely used in children. We proposed to evaluate TBS with bone age (BA) compared to chronological age (CA). In girls, TBS value using BA is constant until age 8, and in boys until age 10, and then starts to increase steadily. This data may help widen TBS use in pediatric populations. Introduction Trabecular bone score (TBS) is a software-based tool for the analysis of DXA images to assess bone microarchitecture in the lumbar region. It is used widely in adults to improve evaluation of fracture risk, yet it has been rarely studied in children and no normal curves have been developed for pediatrics. The purpose of this study was to evaluate bone (skeletal) age compared to chronological age to determine which is better in the pediatric population since both bone age (BA) and trabecular density are equally susceptible to change in response to similar factors. Methods Total body, lumbar region, and non-dominant hand scans were obtained with an iDXA device in all participants. DXA scans of lumbar region for TBS analysis and AP images of non-dominant hand-for-BA were obtained for 565 children (269 female) aged 4to 19. Results Simple correlation was calculated and r2 values for TBS and chronological age were obtained by linear regression, with low correlations (0.36 for boys and 0.38 for girls), and then we created Loess curves to show the change for consecutive ages. In girls, the curve forms a U shape with a nadir point at approximately age 10. We then replaced chronological age with BA, and significant change was seen in the girls’ curve, where a turning point is seen at age 8. In boys, a similar trend shows a turning point at age 10. Finally, BA-corrected TBS curves were constructed using LMS, obtaining curves with percentiles. Conclusions The use of BA in the analysis and interpretation of TBS may help widen its use in pediatric populations by enabling the appearance of normative data, but more information is needed to confirm this finding.

  • Risk factors for conservative treatment failure in acute osteoporotic
           vertebral compression fractures (OVCFs)
    • Abstract: Summary This study aimed to identify risk factors for failure of conservative treatment of acute OVCFs. The results showed age, BMD, BMI, mFI, and IVC were high-risk factors for failure of conservative treatment of acute OVCFs. Purpose This study aimed to identify risk factors for failure of conservative treatment of acute osteoporotic vertebral compression fractures (OVCFs). Methods This is a retrospective study of patients presenting with acute OVCFs who were initiated on conservative treatment for 3 weeks. Conservative treatment was considered to have failed if patients were not satisfied with pain relief or there were bed rest-related complications. These patients progressed to operation. Patients were divided into a conservative treatment failure group (group A) and a conservative treatment group (group B). X-ray, computed tomography and magnetic resonance imaging of two groups were performed on the first visit to our department due to OVCFs. Recorded data for comparison among groups included age, gender, fracture level, bone mineral density (BMD), body mass index (BMI), modified frailty index (mFI), whether the fractures were multiple (≥ 2 vertebral bodies was defined as multiple vertebral fractures) or combined with old fractures, and whether intervertebral cleft (IVC) was present. Results We collected data from 173 patients who underwent conservative treatment of acute OVCF in our hospital. Of these, 71 had conservative treatment failure, while 102 patients succeeded in long-term conservative treatment. After logistic regression analysis, age, BMD, BMI, mFI, and IVC were identified as high-risk factors for conservative treatment failure (P < 0.05). Age, BMD, BMI, and mFI were included in receiver operating characteristic curve analysis, the result showed that the cutoff value of age was 73.5 years old, of BMI was 23.65 kg/m2, of BMD was − 3.45, and mFI was 2.5. Conclusion According to the results of this study, patients with high-risk factors should be actively observed during conservative treatment, especially for patients with all of the above risk factors, but further research would be required before considering early-stage treatment policy change.
