Abstract
Osteoporosis and cardiovascular disease frequently occur together in older adults; however, a causal relationship between these 2 common conditions has not been established. By the time clinical cardiovascular disease develops, it is often too late to test whether vascular dysfunction developed before or after the onset of osteoporosis. Therefore, we assessed the association of vascular function, measured by tonometry and brachial hemodynamic testing, with bone density, microarchitecture, and strength, measured by HR-pQCT, in 1391 individuals in the Framingham Heart Study. We hypothesized that decreased vascular function (pulse wave velocity, primary pressure wave, brachial pulse pressure, baseline flow amplitude, and brachial flow velocity) contributes to deficits in bone density, microarchitecture and strength, particularly in cortical bone, which is less protected from excessive blood flow pulsatility than the trabecular compartment. We found that individuals with increased carotid-femoral pulse wave velocity had lower cortical volumetric bone mineral density (tibia: -0.21 [-0.26, -0.15] standardized beta [95% CI], radius: -0.20 [-0.26, -0.15]), lower cortical thickness (tibia: -0.09 [-0.15, -0.04], radius: -0.07 [-0.12, -0.01]) and increased cortical porosity (tibia: 0.20 [0.15, 0.25], radius: 0.21 [0.15, 0.27]). However, these associations did not persist after adjustment for age, sex, height, and weight. These results suggest that vascular dysfunction with aging may not be an etiologic mechanism that contributes to the co-occurrence of osteoporosis and cardiovascular disease in older adults. Further study employing longitudinal measures of HR-pQCT parameters is needed to fully elucidate the link between vascular function and bone health.

Heliyon 2022; 8:e12266. [PMID: 36582704 PMCID: PMC9792747 DOI: 10.1016/j.heliyon.2022.e12266] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2022] [Revised: 10/14/2022] [Accepted: 11/30/2022] [Indexed: 12/15/2022] Open
Abstract
The present study was carried out to assess the possible changes in mandibular bone density according to age and gender through dental panoramic radiographs (PAN). More specifically, the region of the mandibular oblique line. Materials & methods A group of 374 dental patients previously treated in the Ribeirão Preto Dental School (FORP/USP) was included in the study. The complete dental profiling of all the subjects (including PAN images) was previously available in the archive of the same institution. Those subjects were separated into four groups considering age and gender: Group 1-100 young adult men (21.48 ± 3.34 y. o.), Group 2-100 young adult women (20.66 ± 1.52 y. o.), Group 3-87 postmenopausal women (74.07 ± 9.82 y. o.), and Group 4-87 men over 70 years old (75.92 ± 8.71 y. o.). A new index called "W-index" (WI) was proposed for analyzing the possible difference in mandibular bone density. This new index is the ratio between the average pixel value of the image area of the mandibular ramus (AVMR) and the average pixel value of the image area of the mandibular oblique line (AVOL) (WI = AVMR/AVOL). WI was measured for each subject on each PAN and statistical analysis was performed to search how well WI can characterize each study group. Results The largest difference in WI is observed when we compare older subjects (WI 0.73 ± 0.11) with younger subjects (0.89 ± 0.05). WI also varies significantly with gender but in a smaller amount. Mean WI for old women (0.68 ± 0.11) was found lower than for old men (0.77 ± 0.09), and mean WI for young women (0.89 ± 0.05) was also inferior to young men (0.91 ± 0.05). The differences in WI observed in the subject group were tested for a significance level of α = 0,01. We speculate that WI refers to an aspect of bone mineral density. First, the sharp contrast of the mandibular oblique line may signify the loss of mandibular bone mass. And second, it showed to vary significantly with gender and age, but with higher intensity with age. Clinical significance WI might be used in the future for low bone mineral density risk assessment.

Abstract
The prevalence of multiple falls is higher in older women, and knee pain is associated with multiple falls in women; thus, it is important to detect individuals at risk of fractures among women with knee osteoarthritis. We aimed to clarify the association between knee osteoarthritis and the quantitative ultrasound (QUS) parameter, and investigate the clinical relevance of the QUS parameter with osteoarthritis-related characteristics in women with knee osteoarthritis. This was a cross-sectional study. We recruited 101 women with knee osteoarthritis at a local orthopedic hospital and 102 healthy individuals from the community. Heel QUS measurements were performed using the QUS device, measuring the stiffness index. We also assessed knee pain, quadriceps strength, and physical activity in women with knee osteoarthritis. We fitted a multiple regression model to estimate the association between knee osteoarthritis and the stiffness index. We also fitted 3 multiple regression models to investigate the clinical relevance of the QUS parameter with osteoarthritis-related characteristics in women with knee osteoarthritis. Compared with the control group, individuals with grade 2 osteoarthritis did not demonstrate a significant difference in stiffness index (p = 0.68); however, those with grade 3 osteoarthritis (p < 0.001) and 4 (p < 0.001) showed a lower stiffness index than that of the control group. Additionally, although the QUS parameter did not show an association with knee pain score (p = 0.70) or quadriceps strength (p = 0.11), we found a significant association between the QUS parameter and physical activity (p = 0.003). Our results demonstrate that women with moderate or severe knee osteoarthritis showed lower QUS parameters compared to healthy women, and the QUS parameter was associated with physical activity in women with knee osteoarthritis.

The São Paulo Ageing and Health (SPAH) study. Osteoporos Int 2021; 32:747-757. [PMID: 33037462 DOI: 10.1007/s00198-020-05669-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/15/2020] [Accepted: 10/05/2020] [Indexed: 10/23/2022]
Abstract
UNLABELLED We ascertained the incidence of non-vertebral fracture in a low-income Brazilian elderly cohort. To the best of our knowledge, this is the first population-based study to demonstrate the frequency of non-vertebral fracture in elderly Latin Americans. Age, prior fracture, and bone mineral density (BMD) at hip were predictors of fracture. INTRODUCTION No data on incidence of osteoporotic non-vertebral fracture have been reported in low-income countries where the population's aging has been faster. Even in developed countries, currently available prospective data on major fracture rates beyond hip are scarce. The aim of this study is to describe the incidence and risk factors for non-vertebral fracture in a longitudinal prospective Brazilian population-based elderly cohort. METHODS Seven hundred seven older adults (449 women, 258 men) were evaluated at baseline and after a mean follow-up of 4.3 ± 0.8 years. Clinical questionnaire, bone mineral density (BMD), and laboratory tests were performed at baseline. New non-vertebral fracture (hip, proximal humerus, rib, forearm) was determined during the follow-up. Multivariate Poisson regression models were used to identify independent predictors of fracture. RESULTS The age-standardized incidence of non-vertebral fracture was 1562.3/100,000 (1085.7-2248.1/100,000) person-years (pyr) in women and 632.8/100,000 (301.7-1327.3/100,000) in men. Concerning to hip fractures, the incidence was 421.2/100,000 (210.7-842.3/100,000) pyr in women and 89.9/100,000 (12.7-638.5/100,000) in men. In a multivariate analysis, age (RR 2.07, 95% CI 1.13-3.82, p = 0.019, each 10-year increase), prior non-vertebral fracture (RR 3.08, 95% CI 1.36-6.95, p = 0.007), and total hip BMD (RR 1.68, 95% CI 1.11-2.56, p = 0.015, each 1 SD decrease) were predictors of new non-vertebral fracture. In men, fitting a model of risk factors for fracture was prevented by the limited number of events in male sample. CONCLUSION This is the first population-based study to ascertain the incidence of major non-vertebral fractures in elderly Latin Americans, confirming the high frequency of the disorder. Age, prior fracture, and hip BMD were predictors of the short-term incidence of fracture.

Abstract
Osteoporosis and ischemic heart disease (IHD) represent important public health problems. Existing research suggests an association between the two conditions beyond that attributable to shared risk factors, with a potentially causal relationship. In this study, we tested the association of bone speed of sound (SOS) from quantitative heel ultrasound with (i) measures of arterial compliance from cardiovascular magnetic resonance (aortic distensibility [AD]); (ii) finger photoplethysmography (arterial stiffness index [ASI]); and (iii) incident myocardial infarction and IHD mortality in the UK Biobank cohort. We considered the potential mediating effect of a range of blood biomarkers and cardiometabolic morbidities and evaluated differential relationships by sex, menopause status, smoking, diabetes, and obesity. Furthermore, we considered whether associations with arterial compliance explained association of SOS with ischemic cardiovascular outcomes. Higher SOS was associated with lower arterial compliance by both ASI and AD for both men and women. The relationship was most consistent with ASI, likely relating to larger sample size available for this variable (n = 159,542 versus n = 18,229). There was no clear evidence of differential relationship by menopause, smoking, diabetes, or body mass index (BMI). Blood biomarkers appeared important in mediating the association for both men and women, but with different directions of effect and did not fully explain the observed effects. In fully adjusted models, higher SOS was associated with significantly lower IHD mortality in men, but less robustly in women. The association of SOS with ASI did not explain this observation. In conclusion, our findings support a positive association between bone and vascular health with consistent patterns of association in men and women. The underlying mechanisms are complex and appear to vary by sex. © 2020 The Authors.

Abstract
OBJECTIVE The majority of the published studies ascertaining the relationships between low bone mineral density (BMD) and mortality highlighted the elderly population with limited sample size. Our study aimed to ascertain the relationships in general population. METHODS This study ascertained the relationships between BMD levels in femur and lumbar spine with all-cause and cause-specific mortality in the National Health and Nutrition Examination Survey (NHANES) (n = 15,076, mean age 48.6 years). Cox proportional hazards models were adopted to calculate the hazard ratios (HR) and the corresponding 95% confidence intervals (CIs) for mortality. RESULTS During a 6.8-year median follow-up, 1216 men and women in the cohort died. There was a higher risk of all-cause mortality among participants with osteoporosis compared with normal in the regions of total femur (HR = 1.36, 95% CI = 1.07-1.73), femur neck (HR = 1.41, 95% CI = 1.11-1.78), intertrochanter (HR = 1.34, 95% CI = 1.05-1.72), as well as overall (HR = 1.36, 95% CI = 1.09-1.69). Non-linear dose-response analyses showed a statistically significant L-shaped association for all-cause mortality with BMD increment in the regions of total femur, femur neck, trochanter, and intertrochanter. The protective role of higher BMD level in femur for decreased risk of cancer mortality and heart diseases mortality was more evident in male participants and female participants, respectively. CONCLUSIONS In summary, our results revealed that maintaining normal BMD is critical to lower the risk of mortality. The association between higher BMD level in femur and decreased risk of cancer as well as heart diseases mortality varies by gender.

Abstract
Age‐related bone loss is common in older adults. However, the association of low bone mass with incident disability and mortality is not well established. A sample of 738 participants in the Rush Memory and Aging Project (MAP) was evaluated at baseline for bone mineral density (BMD) using quantitative ultrasound at the calcaneus. An annual interview assessed basic activities of daily living (BADL), instrumental activities of daily living (IADL), mobility disability, and history of hip fracture. The associations between baseline BMD and risk of death; incident BADL, IADL, and mobility disability; and hip fracture were investigated using Cox hazard models, adjusting for age, sex, education, race, and body mass index (BMI). The robustness of our findings was evaluated by adjusting for confounding factors and health conditions including joint pain, musculoskeletal medications, smoking status, motor function, global cognition, falls, cardiovascular events, and diabetes. Participants were on average (mean ± SD) 80.9 ± 7.0 years old, 72% female, and 3.8% black, with a baseline BMI of 27.3 ± 5.4 kg/m2, and a baseline of BMD of 0.44 ± 0.14 g/cm2. In models adjusted for age, sex, education, race, and BMI, lower BMD was associated with a higher rate of death (hazard ratio [HR] 1.20; 95% confidence interval [CI], 1.08–1.33), incident BADL disability (HR 1.20; 95% CI, 1.05–1.37), and hip fracture (HR 2.57; 95% CI, 1.72–3.82), but not of IADL disability (HR 1.00; 95% CI, 0.85–1.17) or mobility disability (HR 1.13; 95% CI, 0.97–1.32). The association between BMD and mortality was not significant in fully adjusted models, but the BMD and BADL associations remained significant in models adjusting for both demographic variables and BMD‐modifying health conditions. BMD is associated with incident disability in older adults. © 2020 The Authors. JBMR Plus published by Wiley Periodicals LLC on behalf of American Society for Bone and Mineral Research.

Abstract
INTRODUCTION The importance of this study is to devise an efficient tool for assessing frailty in the ED. The goals of this study are 1) to correlate ultrasonographic (US) measurements of muscle thickness in older ED patients with frailty and 2) to correlate US-measured sarcopenia with falls, subsequent hospitalizations and ED revisits. METHODS Participants were conveniently sampled from a single ED in this prospective cohort pilot study of patients aged 65 or older. Participants completed a Fatigue, Resistance, Ambulation, Illness and Loss of Weight (FRAIL) scale assessment and US measurements of their upper arm muscles, quadricep muscles, and abdominal wall muscles thickness. We conducted one-month follow-up phone calls to assess for falls, ED revisits, and subsequent hospital visits. RESULTS We enrolled 43 patients (mean age of 78.5). Ultrasound measurements of the three muscle groups were not significantly different between frail and non-frail groups. Frail participants had greater bicep asymmetry (a difference of 0.47 cm vs 0.24 cm, p < .01). A predictive logistic regression model using average quadriceps thickness and biceps asymmetry was found to identify frail patients (AUC of 0.816). Participants with subsequent falls had smaller quadriceps (1.18 cm smaller, p < .01). Subsequently hospitalized patients were found to have smaller quadriceps muscles (0.54 cm smaller, p = .03) and abdominal wall muscles (0.25 cm smaller, p = .01). CONCLUSION US measurements of sarcopenia in older patients had mild to moderate associations with frailty, falls and subsequent hospitalizations. Further investigation is needed to confirm these findings.

Abstract
UNLABELLED There was a U-shaped association between hip BMD and all-cause mortality, with the lowest mortality in the 90th percentile in males. However, there was an inverse linear relationship in females. In contrast, the association between lumbar spine BMD and mortality was less evident in males, with no association in females. INTRODUCTION Bone mineral density (BMD) is reported inversely associated with mortality. Although some previous studies provided evidence for nonlinear associations, these were not adequately assessed in most previous works. METHODS We evaluated the nonlinear relationship between BMD and mortality in Asians. Our study involved 8629 participants in the Dong-gu study from 2007 to 2010. Cox proportional hazard regression was used to calculate hazard ratios (HRs) according to BMD categories after adjusting for potential confounders. During a follow-up of 6.7 ± 1.4 years, 712 participants died. RESULTS There was a U-shaped association between hip BMD and all-cause mortality, with the lowest mortality in the 90th percentile in males. However, there was an inverse linear relationship in females. In males, compared with the 75th to 95th percentile group, the < 2.5th percentile group had a 3.89 (95% CI 2.41-6.28)-fold higher risk and the 2.5th to 5th percentile group had a 2.51 (95% CI 1.25-5.04)-fold higher risk. The HR was 2.51 (95% CI 1.25, 5.04) in the > 97.5th percentile group. In females, compared with that in the 75th to 95th percentile group, the HR was 2.33 (95% CI 1.24, 4.39) in the < 2.5th percentile group. In contrast, the association between lumbar spine BMD and mortality was less evident in males, with no association in females. CONCLUSION In conclusion, this study shows that the association between BMD and mortality varies by gender and that high and low BMD are predictors of all-cause mortality in males.

Abstract
Background Accelerated atherosclerosis is considered to be the linking factor between low bone mineral density (BMD) and increased cardiovascular events and mortality, while some coronary angiographic studies do not support this point. In this study, we attempt to provide a distinct comprehensive view of the relationship between BMD and the angiographically determined coronary atherosclerotic burden. Methods A total of 459 consecutive patients with stable chest pain suspected of coronary artery disease (CAD) underwent both dual-energy X-ray absorptiometry scan and selective coronary angiography. The association between BMD and global coronary atherosclerotic plaque burden as represented by the multivessel involvement and the modified Gensini score was analyzed. Results Multivariable analysis revealed that the low BMD at femoral neck and total hip was an independent correlate of multivessel CAD. The T-scores measured at femoral neck and total hip were both negatively and independently associated to the modified Gensini score. These inversely correlated relationships between BMD and CAD were not observed at lumbar spine 1–4. Conclusion This cross-sectional study elucidated an inverse relationship between hip BMD and the modified Gensini score, and low hip BMD values (T-scores) were significantly and independently associated with increased risk of multivessel coronary disease in patients hospitalized for stable chest pain.

Abstract
This study aimed to determine the association between areal and volumetric bone mineral density (BMD) with all-cause mortality in patients with type 2 diabetes (T2D). Associations between BMD and all-cause mortality were examined in 576 women and 517 men with T2D in the Diabetes Heart Study. Volumetric BMD in the thoracic and lumbar spine was measured with quantitative computed tomography. Areal BMD (aBMD) in the lumbar spine, total hip, femoral neck, ultradistal radius, mid radius, and whole body was measured using dual X-ray absorptiometry. Association of BMD with all-cause mortality was determined using sequential models, stratified by sex: (1) unadjusted; (2) adjusted for age, race, smoking, alcohol, estrogen use; (3) model 2 plus history of cardiovascular disease, hypertension, and coronary artery calcification; (4) model 3 plus lean mass; and (5) model 3 plus fat mass. At baseline, mean age was 61.2 years for women and 62.7 years for men. At mean 11.0 ± 3.7 years' follow-up, 221 (36.4%) women and 238 (43.6%) men were deceased. In women, BMD at all skeletal sites (except spine aBMD and whole body aBMD) was inversely associated with all-cause mortality in the unadjusted model. These associations remained significant in the mid radius (hazard ratio per standard deviation = 0.79; p = 0.0057) and distal radius (hazard ratio per standard deviation = 0.76; p = 0.0056) after adjusting for all covariates, including lean mass. In men, volumetric BMD measurements but not aBMD were inversely associated with mortality and only in the unadjusted model. In this longitudinal study, lower baseline aBMD in the radius was associated with increased all-cause mortality in women with T2D, but not men, independent of other risk factors for death.

Abstract
Background The purpose of this study was to determine whether or not circuit training at home affects the calcaneus quantitative ultrasound status as well as other indices of body composition among undergraduate female students. Methods Forty-one adolescents were recruited (18.5 ± 0.6 years old). The stiffness index of the calcaneus, broadband ultrasound attenuation of the calcaneus, speed of sound of the calcaneus, and body frame index. This was a three-month intervention study, so the measurements were conducted at baseline, 2 months later, and 3 months later while the subjects underwent circuit training at home. The subjects were divided into two groups: namely, the exercising group and non-exercising group. Results In the exercising group, broadband ultrasound attenuation of the calcaneus was higher 2 months later (p = 0.033) as well as 3 months later (p = 0.036), and the speed of sound of the calcaneus was higher 3 months later (p = 0.018). In addition, the muscle mass was strongly positively correlated with the calcaneus QUS-SOS (p = 0.004), while the body fat percentage was a strongly negatively correlated with the calcaneus QUS-BUA (p = 0.043). In the non-exercising group, the stiffness index of the calcaneus was higher 2 months later (p = 0.002) as well as 3 months later (p = 0.002). Furthermore, the body percentage was strongly positively correlated with the calcaneus QUS-SI (p = 0.009). Conclusions These findings suggest that the calcaneus quantitative ultrasound status and muscle mass while losing fat mass may be improved by means of a simple exercise regimen within a short period among undergraduate female students.

Abstract
An increasing evidence base suggests that low bone mineral density (BMD) and fractures are associated with cardiovascular disease (CVD). We conducted a systematic review and meta-analysis summarizing the evidence of low BMD and fractures as risk factors for future CVD. Two independent authors searched major databases from inception to August 1, 2016, for longitudinal studies reporting data on CVD incidence (overall and specific CVD) and BMD status and fractures. The association between low BMD, fractures, and CVD across longitudinal studies was explored by calculating pooled adjusted hazard ratios (HRs) ±95% confidence intervals (CIs) with a random-effects meta-analysis. Twenty-eight studies (18 regarding BMD and 10 fractures) followed a total of 1,107,885 participants for a median of 5 years. Taking those with higher BMD as the reference, people with low BMD were at increased risk of developing CVD during follow-up (11 studies; HR = 1.33; 95%CI, 1.27 to 1.38; I2 = 53%), after adjusting for a median of eight confounders. This finding was confirmed using a decrease in one standard deviation of baseline BMD (9 studies; HR = 1.16; 95% CI, 1.09 to 1.24; I2 = 69%). The presence of fractures at baseline was associated with an increased risk of developing CVD (HR = 1.20; 95% CI, 1.06 to 1.37; I2 = 91%). Regarding specific CVDs, low BMD was associated with an increased risk of developing coronary artery disease, cerebrovascular conditions, and CVD-associated death. Fractures at baseline was associated with an increased risk of cerebrovascular conditions and death due to CVD. In conclusion, low BMD and fractures are associated with a small, but significant increased risk of CVD risk and possibly death. © 2017 American Society for Bone and Mineral Research.

Abstract
OBJECTIVE It is highly debated whether associations between osteoporosis and atherosclerosis are independent of cardiovascular risk factors. We aimed to explore the associations between quantitative ultrasound (QUS) parameters at the heel with the carotid artery intima-media thickness (IMT), the presence of carotid artery plaques, and the ankle-brachial index (ABI). METHODS The study population comprised 5680 men and women aged 20-93 years from two population-based cohort studies: Study of Health in Pomerania (SHIP) and SHIP-Trend. QUS measurements were performed at the heel. The extracranial carotid arteries were examined with B-mode ultrasonography. ABI was measured in a subgroup of 3853 participants. Analyses of variance and linear and logistic regression models were calculated and adjusted for major cardiovascular risk factors. RESULTS Men but not women had significantly increased odds for carotid artery plaques with decreasing QUS parameters independent of diabetes mellitus, dyslipidemia, and hypertension. Beyond this, the QUS parameters were not significantly associated with IMT or ABI in fully adjusted models. CONCLUSIONS Our data argue against an independent role of bone metabolism in atherosclerotic changes in women. Yet, in men, associations with advanced atherosclerosis, exist. Thus, men presenting with clinical signs of osteoporosis may be at increased risk for atherosclerotic disease.

Abstract
OBJECTIVE Vertebral fracture is the most common osteoporotic fracture, affecting quality of life and increasing mortality. Epidemiological data on incidence of vertebral fracture are scarce in Brazil and throughout Latin America. Our aim was to determine vertebral fracture incidence and risk factors in a female Brazilian population. SUBJECTS AND METHODS Postmenopausal women with low bone mass were studied from the Brazilian placebo group of Arzoxifene Generations Trial (n = 974), followed for up to 5 years. The primary endpoint was new vertebral fractures, detected by X-Ray. Experimental design defined two strata: A. Osteoporosis or previous vertebral fracture with osteopenia; B. Osteopenia without previous fracture. Previous fracture, T-score, ionized calcium, alkaline phosphatase, creatinine and glucose were analyzed at baseline. Crude and adjusted incidence rates of vertebral fractures were estimated and Poisson regression model was used. RESULTS Incidence rate was 7.7 (95% CI of 5.4 to 10.9) per 1,000 person-years (PY), increasing as a function of age. Women with new vertebral fractures had higher prevalence of previous nonvertebral fracture after menopause, were older and had lower lumbar spine (LS) T-score. Fracture risk increased by 46% for each unit reduction in LS T-score. Variables correlated with new vertebral fracture were age (p = 0.034), LS T-score, stratum A (p = 0.001 for both) and previous nonvertebral fracture after menopause (p = 0.019). In the final model, LS T-score was the strongest predictor. CONCLUSIONS Incidence rate of vertebral fracture of 7.7 per 1,000 PY. Age and previous fractures were associated with new vertebral fracture, but LS T-score was the most important predictor.

Abstract
Previous studies have shown a relationship between osteoporosis and increased mortality risk. However, none of these studies performed a concomitant evaluation of the parathyroid hormone (PTH)-calcium-vitamin D axis and bone mass to accurately determine the contribution of each of these parameters to survival in older subjects. Thus, we sought to investigate the association between bone parameters and mortality in a longitudinal, prospective, population-based cohort of 839 elderly subjects. Clinical data (including history of fractures and cardiovascular events) were assessed using a specific questionnaire. Laboratory exams, including serum 25OHD and PTH, were also performed. Bone mineral density (BMD) at the lumbar spine and hip were evaluated using DXA. All analyses were performed at baseline (2005 to 2007). Mortality was recorded during follow-up. Multivariate Cox proportional regression was used to compute hazard ratios for all-cause and cardiovascular mortality. Over a mean 4.06 ± 1.07 years, there were 132 (15.7%) deaths. These individuals were compared to 707 subjects who were alive at the end of the coverage period for mortality data collection. In a multivariate Cox proportional hazards model, age (HR 1.32; 95% CI, 1.13 to 1.55; p = 0.001, for each 5-year increase), male gender (HR 1.90; 95% CI, 1.30 to 2.79; p = 0.001), recurrent falls (more than two in the previous year; HR 1.65; 95% CI, 1.06 to 2.56; p = 0.026), diabetes mellitus (HR 2.17; 95% CI, 1.46 to 3.21; p < 0.001), low physical activity score (HR 1.78; 95% CI, 1.14 to 2.79; p = 0.011), prior cardiovascular event (HR 1.76; 95% CI, 1.18 to 2.63; p = 0.006), total hip BMD (HR 1.41; 95% CI, 1.15 to 1.72; p = 0.001, per each 1 SD decrease), and intact PTH (iPTH) (HR 1.06; 95% CI, 1.04 to 1.08; p < 0.001, per each 10 pg/mL increase) were independently associated with all-cause mortality. The subjects in the highest quartile of PTH (>49 pg/mL) were at a higher risk of cardiovascular death (HR 3.09; 95% CI, 1.36 to 6.99; p = 0.007) compared with the subjects in the lowest quartile (<26 pg/mL). Low BMD and higher PTH were significantly associated with mortality in community-dwelling older adults. These findings support the notion that careful screening of these bone parameters might lead to better management of older patients and improve outcomes in this population. © 2016 American Society for Bone and Mineral Research.

[PMID: 27215171 DOI: 10.1016/j.medengphy.2016.04.018] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2015] [Revised: 02/11/2016] [Accepted: 04/23/2016] [Indexed: 11/30/2022]
Abstract
This work represents a study of a mathematical model that describes the biological response to different mechanical stimuli in a cellular dynamics model for bone remodelling. The biological system discussed herein consists of three specialised cellular types, responsive osteoblasts, active osteoblasts and osteoclasts, three types of signalling molecules, transforming growth factor beta (TGF-β), receptor activator of nuclear factor kappa-b ligand (RANKL) and osteoprotegerin (OPG) and the parathyroid hormone (PTH). Three proposals for mechanical stimuli were tested: strain energy density (SED), hydrostatic and deviatoric parts of SED. The model was tested in a two-dimensional geometry of a standard human femur. The spatial discretization was performed by the finite element method while the temporal evolution of the variables was calculated by the 4th order Runge-Kutta method. The obtained results represent the temporal evolution of the apparent density distribution and the mean apparent density and thickness for the cortical bone after 600 days of remodelling simulation. The main contributions of this paper are the coupling of mechanical and biological models and the exploration of how the different mechanical stimuli affect the cellular activity in different types of physical activities. The results revealed that hydrostatic SED stimulus was able to form more cortical bone than deviatoric SED and total SED stimuli. The computational model confirms how different mechanical stimuli can impact in the balance of bone homeostasis.

Low heel ultrasound parameters predict mortality in men: results from the European Male Ageing Study (EMAS). Age Ageing 2015; 44:801-7. [PMID: 26162912 PMCID: PMC4547925 DOI: 10.1093/ageing/afv073] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2014] [Accepted: 02/02/2015] [Indexed: 11/24/2022] Open
Abstract
Background: low bone mineral density measured by dual-energy x-ray absorptiometry is associated with increased mortality. The relationship between other skeletal phenotypes and mortality is unclear. The aim of this study was to determine the relationship between quantitative heel ultrasound parameters and mortality in a cohort of European men. Methods: men aged 40–79 years were recruited for participation in a prospective study of male ageing: the European Male Ageing Study (EMAS). At baseline, subjects attended for quantitative ultrasound (QUS) of the heel (Hologic—SAHARA) and completed questionnaires on lifestyle factors and co-morbidities. Height and weight were measured. After a median of 4.3 years, subjects were invited to attend a follow-up assessment, and reasons for non-participation, including death, were recorded. The relationship between QUS parameters (broadband ultrasound attenuation [BUA] and speed of sound [SOS]) and mortality was assessed using Cox proportional hazards model. Results: from a total of 3,244 men (mean age 59.8, standard deviation [SD] 10.8 years), 185 (5.7%) died during the follow-up period. After adjusting for age, centre, body mass index, physical activity, current smoking, number of co-morbidities and general health, each SD decrease in BUA was associated with a 20% higher risk of mortality (hazard ratio [HR] per SD = 1.2; 95% confidence interval [CI] = 1.0–1.4). Compared with those in higher quintiles (2nd–5th), those in the lowest quintile of BUA and SOS had a greater mortality risk (BUA: HR = 1.6; 95% CI = 1.1–2.3 and SOS: HR = 1.6; 95% CI = 1.2–2.2). Conclusion: lower heel ultrasound parameters are associated with increased mortality in European men.

Abstract
UNLABELLED The relationship between bone quantitative ultrasound (QUS) and fracture risk was estimated in an individual level data meta-analysis of 9 prospective studies of 46,124 individuals and 3018 incident fractures. Low QUS is associated with an increase in fracture risk, including hip fracture. The association with osteoporotic fracture decreases with time. INTRODUCTION The aim of this meta-analysis was to investigate the association between parameters of QUS and risk of fracture. METHODS In an individual-level analysis, we studied participants in nine prospective cohorts from Asia, Europe and North America. Heel broadband ultrasonic attenuation (BUA dB/MHz) and speed of sound (SOS m/s) were measured at baseline. Fractures during follow-up were collected by self-report and in some cohorts confirmed by radiography. An extension of Poisson regression was used to examine the gradient of risk (GR, hazard ratio per 1 SD decrease) between QUS and fracture risk adjusted for age and time since baseline in each cohort. Interactions between QUS and age and time since baseline were explored. RESULTS Baseline measurements were available in 46,124 men and women, mean age 70 years (range 20-100). Three thousand and eighteen osteoporotic fractures (787 hip fractures) occurred during follow-up of 214,000 person-years. The summary GR for osteoporotic fracture was similar for both BUA (1.45, 95 % confidence intervals (CI) 1.40-1.51) and SOS (1.42, 95 % CI 1.36-1.47). For hip fracture, the respective GRs were 1.69 (95 % CI, 1.56-1.82) and 1.60 (95 % CI, 1.48-1.72). However, the GR was significantly higher for both fracture outcomes at lower baseline BUA and SOS (p < 0.001). The predictive value of QUS was the same for men and women and for all ages (p > 0.20), but the predictive value of both BUA and SOS for osteoporotic fracture decreased with time (p = 0.018 and p = 0.010, respectively). For example, the GR of BUA for osteoporotic fracture, adjusted for age, was 1.51 (95 % CI 1.42-1.61) at 1 year after baseline, but at 5 years, it was 1.36 (95 % CI 1.27-1.46). CONCLUSIONS Our results confirm that quantitative ultrasound is an independent predictor of fracture for men and women particularly at low QUS values.

Abstract
Calcaneal quantitative ultrasound can be used to predict osteoporotic fracture risk, but its ability to monitor therapy is unclear possibly because of its limited precision. We developed a quantitative ultrasound device (foot ultrasound scanner) that measures the speed of sound at the heel with the aim of minimizing common error sources like the position and penetration angle of the ultrasound beam, as well as the soft tissue temperature. To achieve these objectives, we used a receiver array, mechanics to adjust the beam direction and a foot temperature sensor. In a group of 60 volunteers, short-term precision was evaluated for the foot ultrasound scanner and a commercial device (Achilles Insight, GE Medical, Fairfield, CT, USA). In a subgroup of 20 subjects, mid-term precision (1-mo follow-up) was obtained. Compared with measurement of the speed of sound with the Achilles Insight, measurement with the foot ultrasound scanner reduced precision errors by half (p < 0.05). The study indicates that improvement of the precision of calcaneal quantitative ultrasound measurements is feasible.

Abstract
Although a high serum low-density lipoprotein cholesterol (LDL-C) level is an established risk factor for atherosclerosis, it is unclear whether it is associated with osteoporosis. In this study, the associations between the serum LDL-C level and bone mineral density (BMD), bone metabolic markers, and the presence of prevalent vertebral or non-vertebral fractures were examined. A total of 211 healthy postmenopausal women (age range, 46-80 years) who visited a community health center were recruited consecutively. Their radiographic and biochemical characteristics were collected. Prevalent vertebral and non-vertebral fractures were found in 49 (23.2%) and 36 (17.1%) subjects, respectively. Simple regression analyses showed that the serum LDL-C level was not significantly correlated with lumbar or femoral BMD or serum levels of total amino-terminal propeptide of type I collagen (PINP) or carboxy-terminal telopeptide of type I collagen (CTX). Logistic regression analyses adjusted for age and BMI showed that the increased serum LDL-C level was selected as an index affecting the presence of prevalent non-vertebral fractures, but not vertebral fractures. This result was still significant after additional adjustments for years since menopause, physical activity, previous cardiovascular events, bone markers, BMD, serum Ca, P, Cr, 25(OH)D, grip strength, tandem gait test, and use of drugs for hyperlipidemia [odds ratio 1.76 (1.13-2.73), p=0.012]. These findings suggest that a high serum LDL-C level may be a risk factor for prevalent non-vertebral fragility fractures independent of bone turnover, bone mass, vitamin D insufficiency, or frail status in postmenopausal women, and that it may be detrimental to bone, as well as blood vessels.

Abstract
Osteoporotic fractures impose severe physical, psychosocial, and financial burden both to the patient and the society. Studies on the prevalence of osteoporosis and fragility fractures in Brazil show a wide variation, due to differences in sample size, the population studied, and methodologies. Few studies have been conducted in Brazil about the cost-effectiveness analyses of different intervention options aimed at the diagnosis and treatment of osteoporosis. Investigation and treatment strategies based on cost-effectiveness and scientific evidence are essential in the preparation of public health policies with the ultimate goal of reducing the incidence of fractures and, consequently, the direct and indirect costs associated with them. This article reviews the Brazilian burden of osteoporosis in terms of the prevalence and fractures attributable to the disease, the costs related to the investigation and management, as well as the impact of osteoporosis on the population as a whole and on affected individuals.

Abstract
BACKGROUND Evidence suggest that there are connections between osteoporosis and cardiovascular diseases. OBJECTIVES The aim of the study was to analyze the relationship between radiological measurements of abdominal aorta calcifications (AAC) and bone mineral density (BMD) in postmenopausal women. METHODS In this cross-sectional study were included 125 postmenopausal women 50-84 years of age. BMD of the spine and hip was measured by dual energy X-ray absorptiometry (DXA). AAC were assessed by lateral radiographs of lumbar spine (L1-L4), using the antero-posterior severity score (0-24). Vertebral fractures were evaluated from T4 to L4 using Genant's semiquantitative method. RESULTS Forty-one (32.8%) patients had osteoporosis and 61 (48.8%) had AAC with a mean score of 3.1. Postmenopausal women with AAC were older and had significantly lower femoral neck and trochanteric BMD than subjects without AAC (all p < 0.01). There were no significant differences in the frequency of fractures between subjects with AAC and those without AAC (p > 0.05). In univariate analysis, age, height, weight, femoral and trochanter BMD were significantly associated with the severity of AAC score. In multiple regression analysis, femoral neck BMD, but not lumbar spine, trochanter BMD or age, was an independent predictor of AAC. CONCLUSIONS Reduced femoral neck BMD is negatively associated with the presence of AAC in postmenopausal women. The association between BMD and AAC seems to be age-independent, which suggests a common pathogenesis for bone loss and vascular calcifications.

Abstract
BACKGROUND Pediatric patients undergoing allogeneic hematopoietic cell transplant (HCT) are at risk for low bone mineral density, which may due, in part, to low 25-hydroxyvitamin D levels. PROCEDURE We compared the serum 25-hydroxyvitamin D status of 22 pediatric HCT patients with 100 healthy pediatric controls. We determined the prevalence of and risk factors for 25-hydroxyvitamin D insufficiency and deficiency. RESULTS Serum 25-hydroxyvitamin D levels were lower in the pediatric HCT patients at time of transplant than healthy pediatric controls (median 19.5 ng/ml vs. 31.0 ng/ml, P < 0.001). Of HCT patients, 27% were 25-hydroxyvitamin D deficient (<15 ng/dl) and 68% insufficient (15-29 ng/dl), compared with 4% and 40%, respectively, of healthy pediatric controls (P < 0.001). In multivariable analysis, treatment with HCT, decreased ambient ultraviolet light exposure, non-Caucasian race, and older age were associated with decreased serum 25-hydroxyvitamin D levels. No association was found between 25-hydroxyvitamin D levels and gender, body mass index, dietary vitamin D intake, or patient-reported vitamin D supplementation. Few patients in either group reported sunscreen use, vitamin D supplementation, or recommended dietary vitamin D intake. CONCLUSIONS At time of transplant, pediatric HCT patients frequently have 25-hydroxyvitamin D insufficiency/deficiency, and this occurs more commonly than in the healthy pediatric population. HCT patients rarely follow recommended guidelines to take supplemental vitamin D, consume the Recommended Daily Allowance for vitamin D, or regularly use sunscreen. Further studies are needed to determine whether vitamin D insufficiency/deficiency persists long term in HCT patients and requires dietary and behavioral interventions.

Abstract
Introduction The high prevalence of chronic hepatitis C (CHC) and its consequent cirrhosis has been associated with bone fragility. Whether CHC may cause bone and mineral abnormalities in the absence of hepatocellular dysfunction is still unknown. In this study we aimed to determine the prevalence of osteoporotic vertebral fractures and low BMD measurements in men with non-cirrhotic CHC. Risk factors for low BMD and fractures were also investigated. Methods Morphometric vertebral fractures and BMD measurements were performed in 60 non-cirrhotic untreated men with CHC and 59 healthy controls, matched for age and gender, weight and current smoking. Serum CTx, calcium, phosphate, intact PTH, alkaline phosphatase and vitamin D (25OHD) concentrations were measured in all participants. Clinical risk factors for low BMD and fractures were evaluated by a structured questionnaire as well as details regarding HCV infection. Results Trochanter and total femur BMD were significantly lower in CHC patients as compared to healthy men (p = 0.04). In men 50 years and older, the prevalence of osteoporosis was significantly higher among CHC patients (p = 0.01). Lower levels of physical activities and more often report of prolonged immobilization were observed among CHC patients (p<0.05). Liver inflammation and fibrosis, viral load and genotype did not correlate with BMD measurements. Bone markers and 25OHD concentrations were similar in both groups. Only a few vertebral fractures were observed. Conclusions Our results demonstrate that non-cirrhotic untreated CHC patients have lower BMD at the femur as compared to healthy men in spite of the absence of significant bone and mineral abnormalities.

Abstract
The aim of this study is to describe the prevalence of fractures in men with rheumatoid arthritis (RA) and identify potential risk factors associated with skeletal fragility. We consecutively studied 50 men with RA. Clinical risk factors were evaluated by clinical questionnaire, functional capacity by M-HAQ1, and disease activity by DAS-28. RA men were compared to 52 healthy controls paired for age and BMI. Bone mineral density (BMD) and quantitative ultrasound (QUS) at the heel were performed in all participants. Morphometric vertebral fractures (VF) were classified by a semiquantitative method. Men with RA were 51.7 years old on average and had mean disease duration of 115 months. Fragility fractures were found in 40% of individuals, of which 36% were VF, significantly higher than in healthy controls (p < 0.01). Age, anthropometric data, and lifestyle were similar between RA men with and without fractures. About 94% of the men with RA were on long-term glucocorticoid (GC) use. Patients with fractures were more frequently positive for rheumatoid factor (RF), had longer morning stiffness, and higher DAS-28 when compared to patients without fractures (p ≤ 0.05). In addition, they had significantly lower spine and hip BMD as well as a lower stiffness index (p ≤ 0.05). There was no statistically significant correlation between fracture and cumulative GC use. The final model of logistic regression showed a significant association and interaction between lower weight and physical activity in men with RA and fragility fractures. RA in men as well as in women is a risk factor for fragility fractures. The risk of fractures is higher in patients with positive RF, prolonged morning stiffness, higher scores of disease activity, and lower values of BMD and QUS.

Abstract
Cardiovascular disease and osteoporosis are important causes of morbi-mortality in the elderly and may be mutually related. Low bone mineral density (BMD) may be associated with increased risk of cardiovascular events. We investigated the prevalence of low bone mass and fractures in metabolic syndrome patients with acute coronary events. A case-control study was conducted with 150 individuals (30-80years-old) with metabolic syndrome. Seventy-one patients had had an acute coronary syndrome episode in the last 6months (cases) and the remaining 79 had no coronary event (controls). Cases and controls were matched for gender, BMI and age. DXA measurements and body composition were performed while spine radiographs surveyed for vertebral fractures and vascular calcification. Biochemical bone and metabolic parameters were measured in all patients. No statistically significant difference in BMD and the prevalence of osteopenia, osteoporosis and non-vertebral fractures was observed between cases and controls. The prevalence of vertebral fractures and all fractures was higher in the cases (14.1 versus 1.3%, p=0.003 and 22.5versus7.6%, p=0.010, respectively). Male gender (OR=0.22 95% CI 0.58 to 0.83, p=0.026) and daily intake of more than 3 portions of dairy products (OR=0.19 95% CI 0.49 to 0.75, p=0.017) were associated with lower prevalence of fractures. Cases had higher risk for fractures (OR=4.97, 95% CI 1.17 to 30.30, p=0.031). Bone mass and body composition parameters were not associated with cardiovascular risk factors or bone mineral metabolism. Patients with fragility fractures had higher OPG serum levels than those without fractures (p<0.001). Our findings demonstrated that patients with recent coronary events have a higher prevalence of vertebral fractures independently of BMD.

Abstract
UNLABELLED Meta-analysis of prospective studies shows that quantitative ultrasound of the heel using validated devices predicts risk of different types of fracture with similar performance across different devices and in elderly men and women. These predictions are independent of the risk estimates from hip DXA measures. INTRODUCTION Clinical utilisation of heel quantitative ultrasound (QUS) depends on its power to predict clinical fractures. This is particularly important in settings that have no access to DXA-derived bone density measurements. We aimed to assess the predictive power of heel QUS for fractures using a meta-analysis approach. METHODS We conducted an inverse variance random effects meta-analysis of prospective studies with heel QUS measures at baseline and fracture outcomes in their follow-up. Relative risks (RR) per standard deviation (SD) of different QUS parameters (broadband ultrasound attenuation [BUA], speed of sound [SOS], stiffness index [SI], and quantitative ultrasound index [QUI]) for various fracture outcomes (hip, vertebral, any clinical, any osteoporotic and major osteoporotic fractures) were reported based on study questions. RESULTS Twenty-one studies including 55,164 women and 13,742 men were included in the meta-analysis with a total follow-up of 279,124 person-years. All four QUS parameters were associated with risk of different fracture. For instance, RR of hip fracture for 1 SD decrease of BUA was 1.69 (95% CI 1.43-2.00), SOS was 1.96 (95% CI 1.64-2.34), SI was 2.26 (95%CI 1.71-2.99) and QUI was 1.99 (95% CI 1.49-2.67). There was marked heterogeneity among studies on hip and any clinical fractures but no evidence of publication bias amongst them. Validated devices from different manufacturers predicted fracture risks with similar performance (meta-regression p values > 0.05 for difference of devices). QUS measures predicted fracture with a similar performance in men and women. Meta-analysis of studies with QUS measures adjusted for hip BMD showed a significant and independent association with fracture risk (RR/SD for BUA = 1.34 [95%CI 1.22-1.49]). CONCLUSIONS This study confirms that heel QUS, using validated devices, predicts risk of different fracture outcomes in elderly men and women. Further research is needed for more widespread utilisation of the heel QUS in clinical settings across the world.

Abstract
The prevalence of osteoporosis is expected to increase with the ageing of the world's population. This article reviews the epidemiology, risk factors and health burden of osteoporosis. In the Global Burden of Disease (GBD) Study 2005, osteoporosis is studied as a risk factor for fracture by considering the bone-mineral-density (BMD) measurement as the continuous exposure variable. We have performed a systematic review seeking population-based studies with BMD data measured by dual-X-ray absorptiometry (DXA). The femoral neck was selected as the unique location and all values were converted into Hologic(®) to enable inclusion of worldwide data for analysis. Provisional results on mean BMD values for different world regions are shown in age breakdowns for males and females 50 years or over, as well as mean T-scores using the young, white, female reference of National Health and Nutrition Examination Survey (NHANES) III. Results show remarkable geographical differences and a time trend towards improvement of the BMD values in Asian and European populations.

Abstract
Osteoporosis is a systemic disorder characterized by generalized decrease in bone mineral density. Dental implantology is a specialty with high predictability when both quantity and quality of the bone are respected. Therefore, the diagnosis and the implant treatment in patients with osteoporosis are important. In the current study, a literature review about osteoporosis and dental implant therapy was conducted. PubMed, Cochrane, ISI, Dentistry Oral Science, SciELO, and Bireme databases were consulted over the last 20 years. English- and Portuguese-language articles were included in this revision. Some authors stated that the osteoporotic bone is similar to the proposed model of bone type IV. Randomized clinical studies reported implant failure in patients with osteoporosis after menopause. Studies that contraindicate the use of implants in patients with osteoporosis infer that the impaired bone metabolism led to reduction of bone healing around the implants. Nevertheless, other authors believe that the presence of osteoporosis is not a definitive condition to contraindicate the therapy with dental implants. In these cases, the dentist should perform a proper treatment planning, modifying the implant geometry, and use larger implant diameter and with surface treatment. Thus, osteoporosis is not a contraindication for implant surgery because an accurate analysis of bone quality by means tomography is performed.

Abstract
SUMMARY We studied the nature of the relationship between bone mineral density (BMD) and the risk of death among elderly men. BMD was associated with mortality risk and was independent of adjustments for other co-morbidities. A piecewise linear function described the relationship more accurately than assuming the same gradient of risk over the whole range of BMD (p = 0.020). Low BMD was associated with a substantial excess risk of death, whilst a higher than average BMD had little impact on mortality. INTRODUCTION Previous studies have demonstrated an association between low BMD and an increased risk of death among men and women. The aim of the present study was to examine the pattern of the risk in men and its relation to co-morbidities. METHODS We studied the nature of the relationship between BMD and death among 3,014 elderly men drawn from the population and recruited to the MrOS study in Sweden. Baseline data included general health questionnaires, life style questionnaires and BMD measured using DXA. Men were followed for up to 6.5 years (average 4.5 years). Poisson regression was used to investigate the relationship between BMD, co-morbidities and the hazard function of death. RESULTS During follow-up, 382 men died (all-cause mortality). Low BMD at all measured skeletal sites was associated with increased mortality. In multivariate analyses, the relationship between BMD and mortality was non-linear, and a piecewise linear function described the relationship more accurately than assuming the same gradient of risk over the whole range of BMD (p = 0.020). CONCLUSIONS Low BMD is associated with a substantial excess risk of death compared to an average BMD, whereas a higher than average BMD has a more modest effect on mortality. These findings, if confirmed elsewhere, have implications for the constructing of probability-based fracture risk assessment tools.

Abstract
Introduction Both cardiovascular disease and osteoporosis are important causes of morbidity and mortality in the elderly. The co-occurrence of cardiovascular disease and osteoporosis prompted us to review the evidence of an association between cardiovascular (CV) disease and osteoporosis and potential shared common pathophysiological mechanisms. Methods A systematic literature search (Medline, Pubmed and Embase) was conducted to identify all clinical studies that investigated the association between cardiovascular disease and osteoporosis. Relevant studies were screened for quality according to guidelines as proposed by the Dutch Cochrane Centre and evidence was summarized. Results Seventy studies were included in this review. Due to a large heterogeneity in study population, design and outcome measures a formal meta-analysis was not possible. Six of the highest ranked studies (mean n = 2,000) showed that individuals with prevalent subclinical CV disease had higher risk for increased bone loss and fractures during follow-up compared to persons without CV disease (range of reported risk: hazard ratio (HR) 1.5; odds ratio (OR) 2.3 to 3.0). The largest study (n = 31,936) reported a more than four times higher risk in women and more than six times higher risk in men. There is moderate evidence that individuals with low bone mass had higher CV mortality rates and incident CV events than subjects with normal bone mass (risk rates 1.2 to 1.4). Although the shared common pathophysiological mechanisms are not fully elucidated, the most important factors that might explain this association appear to be, besides age, estrogen deficiency and inflammation. Conclusions The current evidence indicates that individuals with prevalent subclinical CV disease are at increased risk for bone loss and subsequent fractures. Presently no firm conclusions can be drawn as to what extent low bone mineral density might be associated with increased cardiovascular risk.

Abstract
Fractures are the main problems related to bone fragility in postmenopausal women and account for the increase in the risk of new fractures, mortality, and costs. This study's objective was to verify the occurrence of vertebral fragility fracture and correlate it with demographic, behavioral, and clinical factors in a Brazilian population. The cross-sectional study was based on a random sample of elderly women living in Chapecó, Santa Catarina State, Brazil. The sample consisted of 186 white women over 60 years of age. Of these, 48.9% had asymptomatic vertebral fractures, with higher prevalence in T11-12 and L4-5. Adjusted analysis showed a gradient between age and vertebral fracture, while fracture prevalence was 2.3 times higher in women over 80 years. Fracture prevalence was 1.44 times higher in sedentary as compared to non-sedentary women. Due to the high prevalence of asymptomatic vertebral fractures, the authors suggest the use of spinal x-rays in elderly women for fracture screening and prevention.

Abstract
The epidemiology of osteoporotic fractures varies widely among countries and is primarily related to differences in the population and utilization of public healthcare services. Since 1994, over 200 studies about osteoporosis and fractures have been conducted in Brazil, among which 60 have described the current epidemiological status. This work is a compilation of studies published in scientific journals (PubMed, MedLine, Lilacs, SciELO Database) with the respective highlights. Overall, these studies show moderate incidence of hip fracture in subjects over 50 years old. However, the prevalence of all types of bone fragility fracture is higher, ranging from 11% to 23.8%. In addition, there is a high incidence of recurrent falls, which are the main extra-skeletal factor associated with these fractures. According to the national studies, 12 months after femoral fractures, the mortality rate ranged between 21.5% and 30%, and there was also a high rate of physical impairment, deterioration of the quality of life and excessive burden to the healthcare system. Considering its high prevalence and associated mortality and physical impairment, osteoporosis and its main consequence, bone fragility fractures, must be considered a major public health problem in our country.

Abstract
OBJECTIVE To know the morbid-mortality following an osteoporotic hip fracture in elderly patients living in São Paulo. PATIENTS AND METHODS This study evaluated prospectively all patient over 60 years admitted in 2 school-hospitals in the city of São Paulo in a following 6-month period due to a osteoporotic proximal femur fracture. All of them filled up the Health Assessment Questionnaire (HAQ) and had their chart reviewed. After 6 months they were re-interviewed. Linear regression analysis was utilized to determine the factors related to functional ability. RESULTS 56 patients were included (mean age 80.7 +/- 7.9 years old, 80.4% females). After the 6-month follow up the mortality rate was 23.2%. Only 30% of the patients returned to their previous activities, and 11.6% became totally dependent. Factors related to worse functional ability after fracture were HAQ before fracture, institutionalization after fracture and age (r(2) 0.482). The diagnosis of osteoporosis was informed only by 13.9% of them, and just 11.6% received any treatment for that. CONCLUSION Our results showed the great impact of these fractures on mortality and in the functional ability of these patients. Nevertheless, many of our physicians do not inform the patients about the diagnosis of osteoporosis and, consequently, the treatment of this condition is jeopardized.

Abstract
UNLABELLED The Brazilian Osteoporosis Study (BRAZOS) is the first epidemiological study carried out in a representative sample of Brazilian men and women aged 40 years or older. The prevalence of fragility fractures is about 15.1% in the women and 12.8% in the men. Moreover, advanced age, sedentarism, family history of hip fracture, current smoking, recurrent falls, diabetes mellitus and poor quality of life are the main clinical risk factors associated with fragility fractures. INTRODUCTION The Brazilian Osteoporosis Study (BRAZOS) is the first epidemiological study carried out in a representative sample of Brazilian men and women aged 40 years or older with the purpose of identifying the prevalence and the main clinical risk factors (CRF) associated with osteoporotic fracture in our population. METHODS A total of 2,420 individuals (women, 70%) from 150 different cities in the five geographic regions in Brazil, and all different socio-economical classes were selected to participate in the present survey. Anthropometrical data as well as life habits, fracture history, food intake, physical activity, falls and quality of life were determined by individual quantitative interviews. The representative sampling was based on Brazilian National data provided by the 2000 and 2003 census. Low trauma fracture was defined as that resulting of a fall from standing height or less in individuals 50 years or older at specific skeletal sites: forearm, femur, ribs, vertebra and humerus. Sampling error was 2.2% with 95% confidence intervals. Logistic regression analysis models were designed having the fragility fracture as the dependent variable and all other parameters as the independent variable. Significance level was set as p < 0.05. RESULTS The average of age, height and weight for men and women were 58.4 +/- 12.8 and 60.1 +/- 13.7 years, 1.67 +/- 0.08 and 1.56 +/- 0.07 m and 73.3 +/- 14.7 and 64.7 +/- 13.7 kg, respectively. About 15.1% of the women and 12.8% of the men reported fragility fractures. In the women, the main CRF associated with fractures were advanced age (OR = 1.6; 95% CI 1.06-2.4), family history of hip fracture (OR = 1.7; 95% CI 1.1-2.8), early menopause (OR = 1.7; 95% CI 1.02-2.9), sedentary lifestyle (OR = 1.6; 95% CI 1.02-2.7), poor quality of life (OR = 1.9; 95% CI 1.2-2.9), higher intake of phosphorus (OR = 1.9; 95% CI 1.2-2.9), diabetes mellitus (OR = 2.8; 95% CI 1.01-8.2), use of benzodiazepine drugs (OR = 2.0; 95% CI 1.1-3.6) and recurrent falls (OR = 2.4; 95% CI 1.2-5.0). In the men, the main CRF were poor quality of life (OR = 3.2; 95% CI 1.7-6.1), current smoking (OR = 3.5; 95% CI 1.28-9.77), diabetes mellitus (OR = 4.2; 95% CI 1.27-13.7) and sedentary lifestyle (OR = 6.3; 95% CI 1.1-36.1). CONCLUSION Our findings suggest that CRF may contribute as an important tool to identify men and women with higher risk of osteoporotic fractures and that interventions aiming at specific risk factors (quit smoking, regular physical activity, prevention of falls) may help to manage patients to reduce their risk of fracture.

Abstract
UNLABELLED In a cohort of 5,201 women [72.3 +/- 5.3 years] from 58 primary care centers in Spain, followed for three years, no relationship between heel QUS parameters and overall mortality was found. However, a significant relationship between a low speed of sound (SOS) and vascular mortality was observed. INTRODUCTION An inverse relationship between mortality and bone mineral density measured by dual-energy absorption densitometry or quantitative bone ultrasound (QUS) has been described. The aim of the present study was to test this relationship in the ECOSAP cohort, a 3-year prospective study designed to assess the ability of heel QUS and clinical risk factors to predict non-vertebral fracture risk in women over 64. METHODS A cohort of 5,201 women [72.3 +/- 5.3 years] was studied. QUS was assessed with the Sahara(R) bone sonometer. Women attended follow-up visits every 6 months. Physicians recorded if the patient died and cause of death. Hazard rates (HR) of all-cause and vascular mortality per one standard deviation reduction in QUS parameters were determined. RESULTS One hundred (1.9%) women died during a median of 36.1 months follow-up, for a total of 14,999 patient-years, 42 because of vascular events (both cardiovascular and cerebrovascular). After adjusting for age, none of the QUS variables showed statistically significant differences between the patients who died and the survivors. In the final multivariate model, adjusted for age, current thyroxine and hypoglycaemic drug use, chronic obstructive pulmonary disease and decreased visual acuity, SOS was marginally non-significant: (HR: 1.19; 0.97-1.45). However, each 1 SD reduction in SOS was associated with a 39% increase in vascular mortality (HR: 1.39; 1.15-1.66). CONCLUSIONS In our cohort, SOS was related with vascular mortality, but not overall mortality.

Abstract
This multicenter, open-label study evaluated the effects of short-term risedronate on bone resorption and patient satisfaction in postmenopausal women with osteoporosis in Brazil. Entry requirements included: osteoporosis of the spine/femoral neck diagnosed by a bone mineral density (BMD) T-score<or=-2.5 or radiographic fragility fracture within the last year and no treatment with osteoporosis medication in the preceding 3 mo. Patients were treated with once weekly risedronate of 35 mg for 12 wk. Patients also received 1000 mg calcium carbonate and 400 IU vitamin D. The main outcome was the effect on bone resorption, as assessed by the quantification of serum C-telopeptide of type I collagen (CTX). Of the 556 women screened, 480 women received >or=1 dose of study drug (intent-to-treat [ITT] population), and 390 completed treatment (81%). After 12 wk, CTX decreased in 94% of patients (from 0.419+/-0.234 to 0.158+/-0.171 microg/L, p<0.0001). Mean CTX reduction was 60.6%. Patient satisfaction was good/excellent in 91.7% of patients. A total of 156 adverse events (AEs) were reported by 113 (23.5%) patients in the ITT population. Digestive symptoms emerged or worsened in 7.1% and 3.5%, respectively. Five patients (1.0%) experienced serious AEs, not considered to be related to risedronate. In conclusion, risedronate significantly reduced serum CTX after 12-wk treatment. Almost all patients reported good/excellent satisfaction.

Quantitative ultrasound in the management of osteoporosis: the 2007 ISCD Official Positions. J Clin Densitom 2008; 11:163-87. [PMID: 18442758 DOI: 10.1016/j.jocd.2007.12.011] [Citation(s) in RCA: 248] [Impact Index Per Article: 15.5] [Reference Citation Analysis] [Abstract] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/05/2007] [Accepted: 12/05/2007] [Indexed: 12/19/2022]
Abstract
Dual-energy X-ray absorptiometry (DXA) is commonly used in the care of patients for diagnostic classification of osteoporosis, low bone mass (osteopenia), or normal bone density; assessment of fracture risk; and monitoring changes in bone density over time. The development of other technologies for the evaluation of skeletal health has been associated with uncertainties regarding their applications in clinical practice. Quantitative ultrasound (QUS), a technology for measuring properties of bone at peripheral skeletal sites, is more portable and less expensive than DXA, without the use of ionizing radiation. The proliferation of QUS devices that are technologically diverse, measuring and reporting variable bone parameters in different ways, examining different skeletal sites, and having differing levels of validating data for association with DXA-measured bone density and fracture risk, has created many challenges in applying QUS for use in clinical practice. The International Society for Clinical Densitometry (ISCD) 2007 Position Development Conference (PDC) addressed clinical applications of QUS for fracture risk assessment, diagnosis of osteoporosis, treatment initiation, monitoring of treatment, and quality assurance/quality control. The ISCD Official Positions on QUS resulting from this PDC, the rationale for their establishment, and recommendations for further study are presented here.

Low bone mineral density and mortality in men and women: the Third National Health and Nutrition Examination Survey linked mortality file. Ann Epidemiol 2008; 18:847-50. [PMID: 18809342 DOI: 10.1016/j.annepidem.2008.07.003] [Citation(s) in RCA: 34] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2008] [Revised: 06/19/2008] [Accepted: 07/10/2008] [Indexed: 11/21/2022]
Abstract
PURPOSE The aim of this study is to determine the association of bone mineral density and mortality over a median follow-up of 9 years. METHODS The baseline data used are from the Third National Health and Nutrition Examination Survey (NHANES III), a nationally representative sample of non-institutionalized civilians. A cohort of 5,769 non-Hispanic whites, non-Hispanic blacks, and Mexican Americans aged 50 years and older at baseline (1988-1994) was followed through 2000 for overall mortality using the restricted-use NHANES III Linked Mortality File (1,741 deaths). Total proximal femoral bone mineral density was measured by dual-energy x-ray absorptiometry and categorized into quartiles. Cox proportional hazards models were used to estimate the relative risk of death after adjusting for multiple risk factors. RESULTS Compared with subjects in the highest quartile of bone mineral density, those in the lowest quartile had greater risk of death (relative risk, 1.53; 95% confidence interval: 1.08-2.18; P=0.02). There was no significant interaction of bone mineral density with race or ethnicity. CONCLUSION Low bone mineral density was associated with increased risk of death.

Abstract
For the detection and management of osteoporosis and osteoporosis-related fractures, quantitative ultrasound (QUS) is emerging as a relatively low-cost and readily accessible alternative to dual-energy X-ray absorptiometry (DXA) measurement of bone mineral density (BMD) in certain circumstances. The following is a brief, but thorough review of the existing literature with respect to the use of QUS in 6 settings: 1) assessing fragility fracture risk; 2) diagnosing osteoporosis; 3) initiating osteoporosis treatment; 4) monitoring osteoporosis treatment; 5) osteoporosis case finding; and 6) quality assurance and control. Many QUS devices exist that are quite different with respect to the parameters they measure and the strength of empirical evidence supporting their use. In general, heel QUS appears to be most tested and most effective. Overall, some, but not all, heel QUS devices are effective assessing fracture risk in some, but not all, populations, the evidence being strongest for Caucasian females over 55 years old. Otherwise, the evidence is fair with respect to certain devices allowing for the accurate diagnosis of likelihood of osteoporosis, and generally fair to poor in terms of QUS use when initiating or monitoring osteoporosis treatment. A reasonable protocol is proposed herein for case-finding purposes, which relies on a combined assessment of clinical risk factors (CR.F) and heel QUS. Finally, several recommendations are made for quality assurance and control.
