Health-related quality of life in postmenopausal women with low BMD with or without prevalent vertebral fractures

Osteoporosis is associated with depression among older adults: a nationwide population-based study in the USA from 2005 to 2020

OBJECTIVES

The global prevalence of osteoporosis is rising, yet it is unclear whether people with osteoporosis have a higher risk of depression than those without osteoporosis.

STUDY DESIGN

A cross-sectional study.

METHODS

We used nationally representative data from the US National Health and Nutrition Examination Survey (NHANES) in 2005-2006, 2007-2008, 2009-2010, 2013-2014, and 2017-2020. The diagnosis of osteoporosis was based on the bone mineral density of the femoral neck measured by dual-energy X-ray absorptiometry. Depression was assessed by the Patient Health Questionnaire-9 (PHQ-9), with a score ≥5 as depressive symptoms and a score ≥10 as probable depression. We used logistic regression models to evaluate the association between osteoporosis and depressive symptoms and probable depression.

RESULTS

We included 11,603 adults (aged 50 years and older, 52.3% male) and observed 5.2% of them had osteoporosis. 31.9% of these osteoporotic people had depressive symptoms, and 10.0% had probable depression. Compared to participants without osteoporosis, those with osteoporosis were 1.73 times more likely to experience depressive symptoms (odds ratio [OR] = 1.73, 95% confidence interval [CI] 1.20-2.50) and 1.91 times more likely to experience probable depression (OR = 1.91, 95% CI 1.02-3.59), after adjusting for sex, age, race/ethnicity, education, marital status, family income, body mass index, smoking, physical activity, and alcohol abuse. Moderate-to-vigorous activities mediated the associations between osteoporosis and depression and depressive symptoms.

CONCLUSIONS

Osteoporosis is an independent risk factor for depression. This study highlights the need to evaluate the mental well-being of patients with osteoporosis in clinical and primary health care.

Proportion of Hidden Vertebral Fractures Among Egyptian Males With Fragility Hip Fractures in the Emergency Room of Ain Shams University Hospitals

Background Fragility fractures are linked to significant costs for society as well as significant pain and suffering, disability, and even death. It is well-recognized that osteoporosis-related fragility fractures raise the risk of subsequent fragility fractures. One of the most frequent osteoporotic fractures brought on by low bone mineral density and other risk factors is vertebral fractures. Considering that most vertebral fractures are asymptomatic and not clinically identified, proactive screening could stop additional impairment. Objective The current study aims to determine the prevalence and risk factors of hidden vertebral fractures in Egyptian males who have fragility hip fractures. Patients and methods A cross-sectional case-control study examining the correlation of risk factors between cases (fragility hip fracture and vertebral fractures) and a control group (fragility hip fracture without vertebral fracture) was carried out from September 2020 to September 2021 on patients visiting the orthopedic emergency department of a university hospital in Cairo, Egypt. Males who presented to the emergency room (ER) with fragility hip fractures and were 40 years of age or older met our inclusion criteria. For every patient who presented with a fragility hip fracture, standard lateral and anteroposterior radiographs of the dorso-lumbar spine were taken. Results A total of 43,935 patients visited the orthopedic emergency room (ER) throughout the study period; 13,034 of those patients were men, accounting for 29.7% of all orthopedic ER visits. Our inclusion criteria for fragility hip fractures were met by 132 male participants. The screening lumbosacral plain X-rays identified 27 (20.5%) of the 132 patients as having concomitant vertebral fractures in addition to the fragility hip fractures. Concomitant hidden vertebral fractures among Egyptian males with other fragility fractures, particularly fragility hip fractures, are predicted by the number of co-morbid diseases, hypertension, and continuous use of steroids and anti-epileptics. Conclusion Most fragility fractures are avoidable. Because one fragility fracture increases the likelihood of others, early detection is crucial. To prevent complications and mortality, it is important to identify and manage individuals who have a fragility hip fracture as they frequently have concurrent hidden vertebral fractures. Predictive risk factors for fragility vertebral fractures include hypertension, the number of concomitant illnesses, and chronic drugs (anti-epileptics and steroids).

Low disease activity state associated with fewer incident vertebral fractures in Mestizo women with systemic lupus erythematosus

BACKGROUND

Low disease activity state (LDAS) has been linked to a significant reduction in flares and damage accrual in patients with systemic lupus erythematosus (SLE); however, the effect of LDAS on the risk of vertebral fractures (VFs) in subjects with SLE is unknown, considering that low bone mineral density (BMD) and VF are frequent in SLE.

OBJECTIVE

to evaluate whether achieving LDAS ≥50% of the observation time prevents new VF and BMD changes in Mestizo women.

METHODS

We carried out a longitudinal, observational, and retrospective study. Mestizo women with SLE were included for a median of an 8-year follow-up. LDAS was described as Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) score ≤4, prednisone ≤7.5 mg/day, and stable immunosuppressive therapies. BMD measurements and lateral thoracic and lumbar radiographs for a semiquantitative analysis for VF were assessed at baseline and during the follow-up. Uni- and multivariable interval-censored survival regression models were carried out.

RESULTS

We included 110 patients: 35 (31.8%) had new VF. A total of 56 patients (50.1%) achieved LDAS ≥50% of the time during the follow-up and achieved a significantly lesser risk of incident VF (HR = 0.16; 95% CI, 0.06-0.49). After adjusting by age, BMI, menopause, prevalent VF, baseline BMD, cumulative glucocorticoid use, and anti-osteoporotic therapy, LDAS-50 was significantly related to a decrease in the risk of a new VF (HR = 0.39; 95% CI, 0.16-0.98). There was no association between LDAS and BMD measurement changes. When only patients on LDAS but not in remission (n = 43) were evaluated for the risk of incident VF, both uni- and multivariate analyses were significant (HR = 0.12; 95 CI, 0.04-47; p = 0.001, and HR = 0.26; 95% CI, 0.7-0.88; p = 0.03).

CONCLUSIONS

LDAS ≥50% of the time was significantly associated with a diminished risk of new VF in Mestizo women with SLE, even in patients not in remission. However, LDAS did not help modify BMD changes over time.

Fracture risk among patients with cancer compared to individuals without cancer: a population-based study

BACKGROUND

Patients with cancer may be at increased risk of osteoporosis and fracture; however, gaps exist in the existing literature and the association between cancer and fracture requires further examination.

METHODS

We conducted a population-based cohort study of Ontario patients with cancer (breast, prostate, lung, gastrointestinal, haematologic) diagnosed between January 2007 to December 2018 and 1:1 matched non-cancer controls. The primary outcome was incident fracture (end of follow-up December 2019). Multivariable Cox regression analysis was used to estimate the relative fracture risk with sensitivity analysis accounting for competing risk of death.

RESULTS

Among 172,963 cancer patients with non-cancer controls, 70.6% of patients with cancer were <65 years old, 58% were female, and 9375 and 8141 fracture events were observed in the cancer and non-cancer group, respectively (median follow-up 6.5 years). Compared to non-cancer controls, patients with cancer had higher risk of fracture (adjusted HR [aHR] 1.10, 95% CI 1.07-1.14, p < 0.0001), which was also observed for both solid (aHR 1.09, 95% CI 1.05-1.13, p < 0.0001) and haematologic cancers (aHR 1.20, 95% CI 1.10-1.31, p < 0.0001). Sensitivity analysis accounting for competing risk of death did not change these findings.

CONCLUSIONS

Our study indicates that patients with cancer are at modest risk of fractures compared to non-cancer controls.

Histomorphometric analysis of osteocyte density and trabecular structure of 92 vertebral bodies of different ages and genders

BACKGROUND

Knowledge of the histomorphometric structure of the vertebral body and factors influencing the structure is essential for a fundamental understanding of osteoporosis and osteoporotic fractures. The present study is focused on osteocyte density - a parameter seldom investigated so far - and trabecular width as well as bone area over tissue area in human vertebral bodies.

METHODS

Ninety-two vertebral body specimens (C5, C6, Th8, Th12, L1, L2) from 12 males and seven females were studied (Ethics Application Number A 2017-0072). The prepared vertebral specimens were extracted from the ventral aspect with a Jamshidi needle®. The punches were decalcified and subsequently H&E stained. Using the Fiji/Image J program (version 1.53 f, Wayne Resband, National Institute of Mental Health, USA), osteocyte numbers were counted per calcified bone surface, and the trabecular width and bone area of trabecular bone were measured. The collected data were analyzed using the statistical software package SPSS, version 23.0 (SPSS Inc., Chicago, USA). Pearson's correlation coefficient was used for correlation analyses. Multiple linear regression analyses were also performed.

RESULTS

Osteocyte density did not differ significantly in comparisons based on gender and age (≤65 years; ≥66 years). Men had wider trabeculae (p < 0.001) and a higher bone area over tissue area (BA/TA, %) (p = 0.025) than women. Individuals over 65 years of age had thinner trabeculae (p < 0.001) and a smaller BA/TA (%) (p < 0.001) than younger individuals. Multiple linear regression analyses were performed to determine the influence of 'gender' and 'age' on trabecular width and bone area over tissue area. The R² was 0.388 for trabecular width and 0.227 for BA/TA (%). Per year of life, trabecular width decreases by 0.368 µm (β < 0.001) and BA/TA (%) by 0.001% (β = 0.001). Men have on average 8.2 µm wider trabeculae than women (β = 0.035). A negative correlation (r = -0.275) was observed between trabecular width and osteocyte density. The wider the trabeculae, the fewer osteocytes per mm² (p = 0.008).

CONCLUSIONS

Surprisingly, we found no difference in osteocyte density with reference to age or gender. However, we did register significant age- and gender-related differences in bone area over tissue area and trabecular thickness. The age-related differences were more pronounced, implying that age-dependent loss of bone structure may be more important than differences between genders.

Comparison of Efficacy of Percutaneous Vertebroplasty versus Percutaneous Kyphoplasty in the Treatment of Osteoporotic Vertebral Asymmetric Compression Fracture

BACKGROUND

This study aims to compare the clinical efficacy of percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP) in the treatment of osteoporotic vertebral asymmetric compression fracture (OVACF).

METHODS

This study retrospectively reviewed the patients who were diagnosed with OVACF between September 2015 and July 2019. Forty-one patients received PVP surgery (group A), and 44 patients received PKP surgery (group B). The visual analog scale, Oswestry Disability Index, scoliosis angle (SA), height of long side, height of short side (HS), and lateral height difference (LHD) before operation and 3 days and 1 year after operation were compared between both groups. The operation time, fluoroscopic time, hospital stay, cement volume, and complications were also compared between both groups.

RESULTS

The visual analog scale and Oswestry Disability Index differed significantly between the groups 1 year after operation (P < 0.05). Compared with the preoperative results, there were significant differences in SA, height of long side, HS, and LHD 3 days and 1 year after operation (P < 0.05). Compared with group A, group B showed significantly better in SA, HS, and LHD in group B 3 days and 1 year after operation (P < 0.05). More patients in group A suffered cement leakage and scoliosis than group B after operation (P < 0.05).

CONCLUSIONS

In our study, PVP and PKP are both effective in the treatment of OVACF, but PKP surgery had better long-term clinical efficacy.

Zoledronate Reduces Height Loss Independently of Vertebral Fracture Occurrence in a Randomized Trial in Osteopenic Older Women

Vertebral fractures are associated with height loss, reduced quality of life, and increased mortality and are an important endpoint for osteoporosis trials. However, height loss is associated with quality of life and mortality independent of associations with fracture. We have used data from a recent 6-year trial of zoledronate in 2000 osteopenic women aged >65 years to assess the impact of the semiquantitative and quantitative components of the definition of vertebral fracture on the outcome of that trial, to determine what factors impacted on height loss and to test whether height loss can be used as a surrogate for vertebral fracture incidence. In the trial protocol, an incident vertebral fracture was defined as a change in Genant grade plus both a 20% and 4 mm decrease in a vertebral height. The addition of the quantitative criteria reduced the number of fractures detected but did not change the size of the anti-fracture effect (odds ratios of 0.49 versus 0.45) nor the width of the confidence intervals for the odds ratios. Multivariate analysis of baseline predictors of height change showed that age accelerated height loss (p < 0.0001) and zoledronate reduced it (p = 0.0001). Incident vertebral fracture increased height loss (p = 0.0005) but accounted for only 0.7% of the variance in height change, so fracture could not be reliably inferred from height loss. In women without incident vertebral fractures, height loss was still reduced by zoledronate (height change: zoledronate, -1.23; placebo -1.51 mm/yr, p < 0.0001). This likely indicates that zoledronate prevents a subtle but widespread loss of vertebral body heights not detected by vertebral morphometry. Because height loss is associated with quality of life and mortality independent of associations with fracture, it is possible that zoledronate impacts on these endpoints via its effects on vertebral body integrity. © 2022 American Society for Bone and Mineral Research (ASBMR).

Risk factors for future osteoporosis in perimenopausal Japanese women

OBJECTIVE

The aims of this study were to investigate trends in bone mineral density (BMD) loss and related factors in early postmenopausal women in Japan, identify risk factors for future osteoporosis, and predict osteoporosis before it occurs.

METHODS

The study population consisted of women who were 50 to 54 years old at the time of the survey in 2002 or 2006. The study included a questionnaire and physical measurement findings (BMD, height, body weight [WT], body mass index [BMI], and handgrip strength). One hundred sixty-seven women continued to participate in the study and had BMD measurements at the 9- or 10-year follow-up of the Japanese Population-based Osteoporosis study. Statistical analyses were performed using Pearson correlation to examine each factor of physical measurement and BMD for lumbar spine (LS) and femoral neck (FN). The receiver operating characteristic curve of this data was also predictive of osteoporosis in 2011 for 2002 data; BMD at the age of 50 to 54 years was then used to predict the likelihood of being diagnosed with osteoporosis 9 and 10 years later.

RESULTS

At the baseline in 2002 and 2006, WT, BMI, height, and handgrip strength were positively correlated with BMD. The optimal cutoff values for BMD in 2006 to predict osteoporosis in 2016 were LS less than 0.834 g/cm 2 and FN less than 0.702 g/cm 2 . These data were also predictive of osteoporosis in 2011 for 2002 data; applying this to the 2002 data, LS/FN had a sensitivity of 92%/100%, a specificity of 87%/81%, a positive predictive value of 55%/48%, and a negative predictive value of 98%/100%. The larger WT and BMI also resulted in a greater decrease in BMD of FN after 9 or 10 years.

CONCLUSIONS

We have identified a cutoff value for BMD to predict future osteoporosis in menopausal women and found a negative correlation between WT and BMI in menopausal women and changes in BMD of the FN over the next 10 years.

Defining the optimum strategy for identifying adults and children with coeliac disease: systematic review and economic modelling

BACKGROUND

Coeliac disease is an autoimmune disorder triggered by ingesting gluten. It affects approximately 1% of the UK population, but only one in three people is thought to have a diagnosis. Untreated coeliac disease may lead to malnutrition, anaemia, osteoporosis and lymphoma.

OBJECTIVES

The objectives were to define at-risk groups and determine the cost-effectiveness of active case-finding strategies in primary care.

DESIGN

(1) Systematic review of the accuracy of potential diagnostic indicators for coeliac disease. (2) Routine data analysis to develop prediction models for identification of people who may benefit from testing for coeliac disease. (3) Systematic review of the accuracy of diagnostic tests for coeliac disease. (4) Systematic review of the accuracy of genetic tests for coeliac disease (literature search conducted in April 2021). (5) Online survey to identify diagnostic thresholds for testing, starting treatment and referral for biopsy. (6) Economic modelling to identify the cost-effectiveness of different active case-finding strategies, informed by the findings from previous objectives.

DATA SOURCES

For the first systematic review, the following databases were searched from 1997 to April 2021: MEDLINE® (National Library of Medicine, Bethesda, MD, USA), Embase® (Elsevier, Amsterdam, the Netherlands), Cochrane Library, Web of Science™ (Clarivate™, Philadelphia, PA, USA), the World Health Organization International Clinical Trials Registry Platform ( WHO ICTRP ) and the National Institutes of Health Clinical Trials database. For the second systematic review, the following databases were searched from January 1990 to August 2020: MEDLINE, Embase, Cochrane Library, Web of Science, Kleijnen Systematic Reviews ( KSR ) Evidence, WHO ICTRP and the National Institutes of Health Clinical Trials database. For prediction model development, Clinical Practice Research Datalink GOLD, Clinical Practice Research Datalink Aurum and a subcohort of the Avon Longitudinal Study of Parents and Children were used; for estimates for the economic models, Clinical Practice Research Datalink Aurum was used.

REVIEW METHODS

For review 1, cohort and case-control studies reporting on a diagnostic indicator in a population with and a population without coeliac disease were eligible. For review 2, diagnostic cohort studies including patients presenting with coeliac disease symptoms who were tested with serological tests for coeliac disease and underwent a duodenal biopsy as reference standard were eligible. In both reviews, risk of bias was assessed using the quality assessment of diagnostic accuracy studies 2 tool. Bivariate random-effects meta-analyses were fitted, in which binomial likelihoods for the numbers of true positives and true negatives were assumed.

RESULTS

People with dermatitis herpetiformis, a family history of coeliac disease, migraine, anaemia, type 1 diabetes, osteoporosis or chronic liver disease are 1.5-2 times more likely than the general population to have coeliac disease; individual gastrointestinal symptoms were not useful for identifying coeliac disease. For children, women and men, prediction models included 24, 24 and 21 indicators of coeliac disease, respectively. The models showed good discrimination between patients with and patients without coeliac disease, but performed less well when externally validated. Serological tests were found to have good diagnostic accuracy for coeliac disease. Immunoglobulin A tissue transglutaminase had the highest sensitivity and endomysial antibody the highest specificity. There was little improvement when tests were used in combination. Survey respondents (n = 472) wanted to be 66% certain of the diagnosis from a blood test before starting a gluten-free diet if symptomatic, and 90% certain if asymptomatic. Cost-effectiveness analyses found that, among adults, and using serological testing alone, immunoglobulin A tissue transglutaminase was most cost-effective at a 1% pre-test probability (equivalent to population screening). Strategies using immunoglobulin A endomysial antibody plus human leucocyte antigen or human leucocyte antigen plus immunoglobulin A tissue transglutaminase with any pre-test probability had similar cost-effectiveness results, which were also similar to the cost-effectiveness results of immunoglobulin A tissue transglutaminase at a 1% pre-test probability. The most practical alternative for implementation within the NHS is likely to be a combination of human leucocyte antigen and immunoglobulin A tissue transglutaminase testing among those with a pre-test probability above 1.5%. Among children, the most cost-effective strategy was a 10% pre-test probability with human leucocyte antigen plus immunoglobulin A tissue transglutaminase, but there was uncertainty around the most cost-effective pre-test probability. There was substantial uncertainty in economic model results, which means that there would be great value in conducting further research.

LIMITATIONS

The interpretation of meta-analyses was limited by the substantial heterogeneity between the included studies, and most included studies were judged to be at high risk of bias. The main limitations of the prediction models were that we were restricted to diagnostic indicators that were recorded by general practitioners and that, because coeliac disease is underdiagnosed, it is also under-reported in health-care data. The cost-effectiveness model is a simplification of coeliac disease and modelled an average cohort rather than individuals. Evidence was weak on the probability of routine coeliac disease diagnosis, the accuracy of serological and genetic tests and the utility of a gluten-free diet.

CONCLUSIONS

Population screening with immunoglobulin A tissue transglutaminase (1% pre-test probability) and of immunoglobulin A endomysial antibody followed by human leucocyte antigen testing or human leucocyte antigen testing followed by immunoglobulin A tissue transglutaminase with any pre-test probability appear to have similar cost-effectiveness results. As decisions to implement population screening cannot be made based on our economic analysis alone, and given the practical challenges of identifying patients with higher pre-test probabilities, we recommend that human leucocyte antigen combined with immunoglobulin A tissue transglutaminase testing should be considered for adults with at least a 1.5% pre-test probability of coeliac disease, equivalent to having at least one predictor. A more targeted strategy of 10% pre-test probability is recommended for children (e.g. children with anaemia).

FUTURE WORK

Future work should consider whether or not population-based screening for coeliac disease could meet the UK National Screening Committee criteria and whether or not it necessitates a long-term randomised controlled trial of screening strategies. Large prospective cohort studies in which all participants receive accurate tests for coeliac disease are needed.

Insuffizienzfrakturen der Wirbelsäule in Abhängigkeit von der spongiösen Knochendichte

Hintergrund

Das Risiko für osteoporotische Insuffizienzfrakturen (Fx) am Achsenskelett steigt mit zunehmender Abnahme der Knochendichte, wobei sich thorakal und thorakolumbal eine Häufung findet. Um die unterschiedliche Verteilung von Fx entlang der Wirbelsäule (WS) besser zu verstehen, wurden morphologische und osteodensitometrische Untersuchungen mittels Computertomographie (CT) in den verschiedenen WS-Abschnitten durchgeführt. Zudem war zu klären, ob die bei CT-Untersuchungen aus anderen Indikationen gefunden Hounsfield-Einheiten (HE) mit der Knochendichte korrelieren und Anlass für eine osteologische Diagnostik sein könnten.

Material und Methoden

Von 26 Körperspenden wurden die gesamten WS in einem Plexiglas-Wasser-Phantom fixiert und mittels hochauflösende Spiral-CT analysiert. Zusätzlich erfolgte die Messung der CT-morphologischen Spongiosadichte in HE von C3 bis S2 (624 Wirbelkörper). Der Knochenmineralgehalt (KMG, mg/ml) wurde ermittelt und zur Abschätzung einer Osteoporose (OPO) herangezogen.

Ergebnisse

Bei allen WS lag eine OPO vor. Bei einem KMG unterhalb von 60 mg/ml fanden sich signifikant vermehrte Sinterungsfrakturen im thorakalen und thorakolumbalen Bereich. Osteoporotische Insuffizienzfrakturen im HWS-Bereich fanden sich insgesamt nicht. Die Spongiosadichte war signifikant höher in den zervikalen (Median 188,6 HE) als in den lumbalen (Median 63,6 HE) und sakralen (Median 25,5 HE) Wirbelkörpern aller untersuchten WS.

Schlussfolgerung

Ein KMG-Verlust der Wirbelkörperspongiosa führt zu einem erhöhten Fx-Risiko, welches sich auch bei den verwendeten WS findet. Jedoch wird im zervikalen Bereich ein scheinbarer Schwellenwert für das Auftreten von Sinterungsfrakturen nicht unterschritten. Einen Schwellenwert für HE zu finden, wäre für die klinische Praxis relevant.

Managements of osteoporotic vertebral compression fractures: A narrative review

Osteoporotic vertebral compression fractures (OVCFs) are the most common fragility fracture and significantly influence the quality of life in the elderly. Currently, the literature lacks a comprehensive narrative review of the management of OVCFs. The purpose of this study is to review background information, diagnosis, and surgical and non-surgical management of the OVCFs. A comprehensive search of PubMed and Google Scholar for articles in the English language between 1980 and 2021 was performed. Combinations of the following terms were used: compression fractures, vertebral compression fractures, osteoporosis, osteoporotic compression fractures, vertebroplasty, kyphoplasty, bisphosphonates, calcitonin, and osteoporosis treatments. Additional articles were also included by examining the reference list of articles found in the search. OVCFs, especially those that occur over long periods, can be asymptomatic. Symptoms of acute OVCFs include pain localized to the mid-line spine, a loss in height, and decreased mobility. The primary treatment regimens are pain control, medication management, vertebral augmentation, and anterior or posterior decompression and reconstructions. Pain control can be achieved with acetaminophen or nonsteroidal anti-inflammatory drugs for mild pain or opioids and/or calcitonin for moderate to severe pain. Bisphosphonates and denosumab are the first-line treatments for osteoporosis. Vertebroplasty and kyphoplasty are reserved for patients who have not found symptomatic relief through conservative methods and are effective in achieving pain relief. Vertebroplasty is less technical and cheaper than kyphoplasty but could have more complications. Calcium and vitamin D supplementation can have a protective and therapeutic effect. Management of OVCFs must be combined with multiple approaches. Appropriate exercises and activity modification are important in fracture prevention. Medication with different mechanisms of action is a critical long-term causal treatment strategy. The minimally invasive surgical interventions such as vertebroplasty and kyphoplasty are reserved for patients not responsive to conservative therapy and are recognized as efficient stopgap treatment methods. Posterior decompression and fixation or Anterior decompression and reconstruction may be required if neurological deficits are present. The detailed pathogenesis and related targeted treatment options still need to be developed for better clinical outcomes.

Breaking strength and bone microarchitecture in osteoporosis: a biomechanical approximation based on load tests in 104 human vertebrae from the cervical, thoracic, and lumbar spines of 13 body donors

Background

The purpose of the study was to investigate associations between biomechanical resilience (failure load, failure strength) and the microarchitecture of cancellous bone in the vertebrae of human cadavers with low bone density with or without vertebral fractures (VFx).

Methods

Spines were removed from 13 body donors (approval no. A 2017-0072) and analyzed in regard to bone mineral density (BMD), Hounsfield units (HU), and fracture count (Fx) with the aid of high-resolution CT images. This was followed by the puncture of cancellous bone in the vertebral bodies of C2 to L5 using a Jamshidi™ needle. The following parameters were determined on the micro-CT images: bone volume fraction (BVF), trabecular thickness (Tb.Th), trabecular separation (Tb.Sp), degree of anisotropy (DA), trabecular number (Tb.N), trabecular pattern factor (Tb.Pf), and connectivity density (Conn.D). The axial load behavior of 104 vertebral specimens (C5, C6, T7, T8, T9, T12, L1, L3) was investigated with a servohydraulic testing machine.

Results

Individuals with more than 2 fractures had a significantly lower trabecular pattern factor (Tb.Pf), which also proved to be an important factor for a reduced failure load in the regression analysis with differences between the parts of the spine. The failure load (FL) and endplate sizes of normal vertebrae increased with progression in the craniocaudal direction, while the HU was reduced. Failure strength (FS) was significantly greater in the cervical spine than in the thoracic or lumbar spine (p < 0.001), independent of sex. BVF, Tb.Th, Tb.N, and Conn.D were significantly higher in the cervical spine than in the other spinal segments. In contrast, Tb.Sp and Tb.Pf were lowest in the cervical spine. BVF was correlated with FL (r = 0.600, p = 0.030) and FS (r = 0.763, p = 0.002). Microarchitectural changes were also detectable in the cervical spine at lower densities.

Conclusions

Due to the unique microarchitecture of the cervical vertebrae, fractures occur much later in this region than they do in the thoracic or lumbar spine.

Clinical predictors of incipient vertebral fractures and bone mineral density in kidney transplant patients

PURPOSE

Kidney transplant recipients are prone to metabolic bone diseases and consequent fractures. This study aimed to evaluate the incidence of incipient vertebral fractures, osteopenia, osteoporosis, and the clinical factors associated with incipient vertebral fractures in a group of kidney transplant patients.

METHODS

Two hundred sixty-four patients (F/M 124/140, 45.3 ± 13 years) who had undergone kidney transplantation in tertiary care centers were included. Vertebral fractures were assessed semiquantitatively using conventional thoracolumbar lateral radiography in 202 of the patients.

RESULTS

Vertebral fractures were observed in 56.4% (n = 114) of the study group. The frequency of osteoporosis was 20.0% (53 of 264 patients), and osteopenia was 35.6% (94 of 264 patients). Bone mineral density (BMD) levels were in the normal range in 40.3% (n = 46) of the subjects with vertebral fractures. It was in the osteoporotic range in 20.1% (n = 23) and the osteopenic range in 40.3% (n = 46). Vertebral fractures were associated with age, duration of hemodialysis, BMI, and femoral neck Z score (R² 37.8%, p = 0.027).

CONCLUSION

As incipient vertebral fractures can be observed in patients with normal BMD levels in kidney transplant recipients, conventional X-ray screening for vertebral fractures may be beneficial for a proper therapy decision of metabolic bone disease in kidney transplant recipients.

The cumulative incidence of and risk factors for morphometric severe vertebral fractures in Japanese men and women: the ROAD study third and fourth surveys

This population-based cohort study with a 3-year follow-up revealed that the annual incidence rates of vertebral fracture (VF) and severe VF (sVF) were 5.9%/year and 1.7%/year, respectively. The presence of mild VF at the baseline was a significant risk factor for incident sVF in participants without prevalent sVF.

INTRODUCTION

This study aimed to estimate the incidence of morphometric vertebral fracture (VF) and severe VF (sVF) in men and women and clarify whether the presence of a mild VF (mVF) increases the risk of incident sVF.

METHODS

Data from the population-based cohort study, entitled the Research on Osteoarthritis/Osteoporosis Against Disability (ROAD) study, were analyzed. In total, 1190 participants aged ≥ 40 years (mean age, 65.0 ± 11.2) years completed whole-spine lateral radiography both at the third (2012-2013, baseline) and fourth surveys performed 3 years later (2015-2016, follow-up). VF was defined using Genant's semi-quantitative (SQ) method: VF as SQ ≥ 1, mVF as SQ = 1, and sVF as SQ ≥ 2. Cumulative incidence of VF and sVF was estimated. Multivariate logistic regression analyses were performed to evaluate risk factors for incident sVF.

RESULTS

The baseline prevalence of mVF and sVF were 16.8% and 6.0%, respectively. The annual incidence rates of VF and sVF were 5.9%/year and 1.7%/year, respectively. The annual incidence rates of sVF in participants without prevalent VF, with prevalent mVF, and with prevalent sVF were 0.6%/year, 3.8%/year, and 11.7%/year (p < 0.001), respectively. Multivariate logistic regression analyses in participants without prevalent sVF showed that the adjusted odds ratios for incident sVF were 4.12 [95% confident interval 1.85-9.16] and 4.53 [1.49-13.77] if the number of prevalent mVF at the baseline was 1 and ≥ 2, respectively.

CONCLUSIONS

The annual incidence rates of VF and sVF were 5.9%/year and 1.7%/year, respectively. The presence of prevalent mVF was an independent risk factor for incident sVF.

Exploring the Association between Pain and Fracture Characteristics in Women with Osteoporotic Vertebral Fractures

Purpose: The purpose of this study was to estimate the association between pain and the number, severity, and location of fractures in women with osteoporotic vertebral fractures. Method:We used an 11-point numeric pain rating scale to assess pain during movement in the preceding week and lateral spinal radiographs to confirm number, location, and severity of vertebral fractures. In model 1, we assessed the association between pain during movement and the number, severity, and location of fractures. We adjusted model 2 for pain medication use and age. Results: The mean age of participants was 76.4 (SD 6.9) years. We found no statistically significant associations between pain and fracture number (estimated β = 0.23, 95% CI: ‒0.27, 0.68), fracture severity (estimated β = ‒0.46, 95% CI: ‒1.38, 0.49), or fracture location at T4–T8 (estimated β = 0.06, 95% CI: ‒1.26, 1.34), T9–L1 (estimated β = 0.35, 95% CI: ‒1.17, 1.74), or L2–L4 (estimated β = 0.40, 95% CI: ‒1.01, 1.75). Age and pain medication use were not significantly associated with pain. Model 1 accounted for 4.7% and model 2 for 7.2% of the variance in self-reported pain. Conclusion: The number, location, and severity of fractures do not appear to be the primary explanation for pain in women with vertebral fractures. Clinicians must consider other factors contributing to pain.

[Topical issues of rehabilitation of patients with osteoporotic vertebral fractures]

The literature review analyzed 20 Russian and 69 foreign publications on the rehabilitation of elderly patients with osteoporotic vertebral fractures. The article deals in detail with the prevalence, medical and social significance of pathological osteoporotic fractures, including vertebral deformities. The data confirming the importance of osteoporosis for physical and rehabilitation medicine specialists are presented. Changes in the quality of life, functional and gate disorders associated with osteoporotic vertebral fractures are described. Based on the available literature data, the principles of rehabilitation of patients with osteoporotic vertebral compression fractures are formulated, including the effectiveness of various methods of physical therapy, mechanotherapy and apparatus physiotherapy. From the standpoint of evidence-based medicine, the role of orthotics in the complex rehabilitation of such patients is described. Based on the analysis of literature data, it was concluded that the problem of osteoporosis is relevant for physicians working in the field of rehabilitation medicine; osteoporotic vertebral fractures are characterized by a high prevalence over the age of 50 years and are associated with a decrease in the quality of life, motor and functional limitations, and an increased risk of death, and well-planned medical rehabilitation programs including physical exercises, physiotherapy and orthotics can significantly improve patient functionality.

The association between incident vertebral deformities, health-related quality of life and functional impairment: a 10.7-year cohort study

We aimed to describe longitudinal changes in health-related quality of life (HRQoL) measures associated with incident vertebral deformities (VDs) over 10.7 years. Incident VDs are associated with clinically significant functional impairment in men, and reduction in overall HRQoL in older women. Increasing severity and number of incident VDs are associated with clinically meaningful functional impairment in men, but not women.

INTRODUCTION

To describe associations between incident VD and changes in HRQoL and functional ability in older adults over 10.7 years.

METHODS

Participants (n = 780) underwent whole-body dual-energy X-ray absorptiometry (DXA) scans at baseline, 2.5, 5.1 and 10.7 years later. VD was defined as ≥ 25% reduction in anterior height relative to posterior height of vertebrae from T4 to L4. An incident VD was defined as a new VD at any follow-up visit. Assessment of Quality of Life (AQoL-4D) questionnaire and Health Assessment Questionnaire-Disability Index (HAQ-DI) were used to assess HRQoL and functional impairment. Changes in AQoL and HAQ-DI associated with incident VD were analysed using multilevel mixed-effects linear regression. Log binomial regression was used to examine clinically relevant changes and effects of severity and number of VD.

RESULTS

The incidence of VD was 37% over 10.7 years. In women, incident VDs were associated with annual reduction in AQoL utility score (β = -0.005, 95% CI -0.008 to -0.002). Men had increased risk of clinically significant reduction in HAQ-DI (IRR = 1.76, 95% CI 1.07-2.89). Men had increased risk of clinically important functional impairment with increasing severity (IRR 1.76, 95% CI 1.04-2.95 for mild vs IRR 1.98, 95% CI 1.13-3.47 for moderate to severe VD) as well as number of incident VD (IRR 1.85, 95% CI 1.17-2.93 for one vs IRR 1.88, 95% CI 0.94-3.78 for ≥ 2 VDs). Such associations were not observed in women.

CONCLUSIONS

Incident VDs are associated with clinically significant functional impairment in men, and reduction in overall HRQoL in older women. Increasing severity and number of incident VDs are associated with clinically meaningful functional impairment in men, but not women.

Vertebral fracture: epidemiology, impact and use of DXA vertebral fracture assessment in fracture liaison services

Vertebral fractures are independent risk factors for vertebral and nonvertebral fractures. Since vertebral fractures are often missed, the relatively new introduction of vertebral fracture assessment (VFA) for imaging of the lateral spine during DXA-measurement of the spine and hips may contribute to detect vertebral fractures. We advocate performing a VFA in all patients with a recent fracture visiting a fracture liaison service (FLS). Fracture liaison services (FLS) are important service models for delivering secondary fracture prevention for older adults presenting with a fragility fracture. While commonly age, clinical risk factors (including fracture site and number of prior fracture) and BMD play a crucial role in determining fracture risk and indications for treatment with antiosteoporosis medications, prevalent vertebral fractures usually remain undetected. However, vertebral fractures are important independent risk factors for future vertebral and nonvertebral fractures. A development of the DXA technology, vertebral fracture assessment (VFA), allows for assessment of the lateral spine during the regular DXA bone mineral density measurement of the lumbar spine and hips. Recent approaches to the stratification of antiosteoporosis medication type according to baseline fracture risk, and differences by age in the indication for treatment by prior fracture mean that additional information from VFA may influence initiation and type of treatment. Furthermore, knowledge of baseline vertebral fractures allows reliable definition of incident vertebral fracture events during treatment, which may modify the approach to therapy. In this manuscript, we will discuss the epidemiology and clinical significance of vertebral fractures, the different methods of detecting vertebral fractures, and the rationale for, and implications of, use of VFA routinely in FLS. • Vertebral fracture assessment is a tool available on modern DXA instruments and has proven ability to detect vertebral fractures, the majority of which occur without a fall and without the signs and symptoms of an acute fracture. • Most osteoporosis guidelines internationally suggest that treatment with antiosteoporosis medications should be considered for older individuals (e.g., 65 years +) with a recent low trauma fracture without the need for DXA. • Younger individuals postfracture may be risk-assessed on the basis of FRAX® probability including DXA and associated treatment thresholds. • Future fracture risk is markedly influenced by both site, number, severity, and recency of prior fracture; awareness of baseline vertebral fractures facilitates definition of true incident vertebral fracture events occurring during antiosteoporosis treatment. • Detection of previously clinically silent vertebral fractures, defining site of prior fracture, might alter treatment decisions in younger or older FLS patients, consistent with recent IOF-ESCEO guidance on baseline-risk-stratified therapy, and provides a reliable baseline from which to define new, potentially therapy-altering, vertebral fracture events.

Comparison of Quality of Life and Bone Mass Density among Postmenopausal Women: A Cross-sectional Study

Background

Postmenopausal women are at highest risk of developing osteoporosis, since their bone mineral density is reduced due to decrease in estrogen level. Various other physiological, emotional, and psychological changes jeopardize the health of these vulnerable females in total and reduce their quality of life (QoL).

Aims and Objectives

To compare the QoL and bone mass density (BMD) among normal BMD, osteopenic, and osteoporotic postmenopausal women.

Setting and Design

A cross-sectional observational study was conducted in the outpatient department of physical medicine and rehabilitation at a tertiary care center of northern India from August 2019 to February 2020.

Materials and Methods

Baseline sociodemographic characteristics of all postmenopausal women were collected using a quantitative tool. Assessment of QoL was done by pretested and validated QUALEFFO-41 scale. For all the women, a bone mineral densitometry test was performed on the L1-L4 lumbar spine, femoral neck, and forearm by the dual-energy X-ray absorptiometry method.

Statistical Analysis

One-way ANOVA test was used to compare the mean BMD values across the three groups. Determination of predictive factors for QoL was performed using stepwise logistic regression analysis.

Results

Significant differences were noted for the mean values of the three domains, i.e., pain, physical, and social function (P < 0.01). Women with osteoporosis had significantly higher pain scores as compared to others. Among those with osteoporosis, the pain scores have significantly increased gradually as age increases.

Conclusion

Postmenopausal women with osteopenia and osteoporosis have poor QoL as compared to those with normal BMD.

Development and Testing of the Quality of Life Osteoporosis Scale-Nonvertebral Fractures (QoLOS-NVFX)

The aim of this study was developing and testing a new tool for measuring quality of life (QoL) in patients with osteoporosis who had experienced nonvertebral fractures (NVFXs). Two main phases were carried out. First, the tool was developed based on expert opinion through three focus groups. Second, the tool was tested with exploratory factor analysis and confirmatory factor analysis in a sample of 458 postmenopausal women. The reliability of the developed Quality of Life Osteoporosis Scale-Nonvertebral Fractures (QoLOS-NVFX) was measured using Cronbach's α, maximal reliability (MR), composite reliability (CR), and average variance extracted (AVE). The QoLOS-NVFX resulted in a unidimensional scale with 23 items and showed good reliability, with a Cronbach's α of 0.94, an MR of 0.96, a CR of 0.96, and an AVE of 0.70. The QoLOS-NVFX shows good psychometric properties and can be used to assess the impact of NVFX on QoL in osteoporotic women. Furthermore, it can be easily used in clinical practice and research.

Impact of Bone Fracture on Muscle Strength and Physical Performance-Narrative Review

PURPOSE OF REVIEW

Low muscle strength and poor physical performance are associated with high risk of fracture. Many studies assessed clinical and functional outcomes of fractures. Fewer studies analyzed the impact of fractures on muscle strength and physical performance.

RECENT FINDINGS

Vertebral fractures (especially multiple and severe ones) are associated with back pain, back-related disability, lower grip strength, lower strength of lower limbs, lower gait speed, and poor balance. Patients with hip fracture have slower gait and lower quadriceps strength. Non-vertebral fractures were associated with lower strength of the muscles adjacent to the fracture site (e.g., grip strength in the case of distal radius fracture, knee extensors in the case of patellar fracture) and poor physical function dependent on the muscles adjacent to the fracture site (e.g., limited range of motion of the shoulder in the case of humerus fracture, gait disturbances in the case of the ankle fracture). Individuals with a fracture experience a substantial deterioration of muscle strength and physical performance which exceeds that related to aging and is focused on the period close to the fracture occurrence. After fracture, muscle strength increased and physical performance improved. The rate of normalization depended partly on the therapeutic approach and on the rehabilitation program. A subgroup of patients, mainly the elderly, never returns to the pre-fracture level of physical performance. The permanent decline of physical function after fracture may be related to the limitation of movements due to pain, low physical activity, poor health before the fracture, and reduced efficacy of retraining after immobilization.

Quality of Life Changes in Women with Osteoporotic Vertebral Fractures and Possibility of its Improvement Using New Complex of Physical Therapy Including Mechanotheraputic Technologies

Objective. To assess quality of life (QOL) in people with osteoporotic (OP) vertebral fractures (VFs) and evaluate effect of new complex of physical rehabilitation including mechanotherapeutic technologies on QOL of those patients. Material and methods. At the 1st stage the study group was comprised of 60 women 40–80 years old with OP VFs. The comparison group (n=60) was formed from patients with OP without any fracture enrolled by the twin-pair method. 2nd stage was carried out inthe form of a prospective controlled open study. 120 patients with OP VFs were randomized to the intervention group (group 1, n=60)which received a new complex of physical therapy including mechanotherapeutic technologies, and control (group 2, n=60) which received only complex of physical exercises. Results. In patients with VFs a significant decrease in main QOL domains such as severity of pain, daily living activity, mobility, mental state, general health and general QUALEFFO-41 scale was revealed (p<0.05 vs comparison group). Administration of a new physical rehabilitation complex resulted in pain reduction and improvement of such QOL aspects as house jobs, mobility and mental state(p<0.05 at 21st day vs baseline). Therapy effect on pain syndrome, daily living activity, mobility and overall QOL remains for at least 4 weeks after the rehabilitation course (p<0.05 at 70th day vs baseline). Conclusion. New physical therapy complex including mechanotherapeutic technologies can be recommended for rehabilitation of patients with osteoporotic VFs to increase QOL and to reduce back pain.

Evaluation of pain, quality of life, and patient satisfaction in parenterally treated patients with postmenopausal osteoporosis

Objectives

This study aims to evaluate pain, quality of life, and patient satisfaction in parenterally treated patients with postmenopausal osteoporosis (OP).

Patients and methods

Between May 2016 and January 2018, a total of 138 patients (mean age 63.78 years; range, 50 to 70 years) with postmenopausal OP were retrospectively analyzed. All patients were previously treated with denosumab (DEN) and parenteral forms of bisphosphonates such as zoledronic acid (ZOL) and ibandronate (IBN). The pain severity was evaluated using the Visual Analog Scale (VAS) and Brief Pain Inventory-Short Form (BPI-SF). The quality of life was evaluated using the Quality of Life Questionnaire of the European Foundation for Osteoporosis (Qualeffo-41). For the evaluation of patient satisfaction, a three-item questionnaire including satisfaction with the medication, route, and frequency of administration was applied.

Results

Of the patients, 50 received DEN, 48 received ZOL, and 40 received IBN treatment. There was no significant difference in any of the pain parameters. All domains of the Qualeffo-41 were similar among the three groups. The patients in the DEN group were more satisfied with their medication (DEN: 88%, ZOL: 43.75%, and IBN: 52.5%), its administration route (DEN: 84%, ZOL: 43.8%, and IBN: 57.5%), and the frequency of its administration (DEN: 84%, ZOL: 56.25%, and IBN: 52.5%) (p=0.0001).

Conclusion

Neither of the medication showed a superior effect on quality of life. However, patients were more satisfied with medications used in a six-month interval and applied subcutaneously. Of these three treatment options, DEN seems to be a step ahead in terms of patient satisfaction.

Fractures are common within 18 months following first-line R-CHOP in older patients with diffuse large B-cell lymphoma

Diffuse large B-cell lymphoma (DLBCL) and osteoporotic fracture are both more common in older patients. Exposure to R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone) is likely to increase the risk of fracture, but evidence is lacking to define fracture incidence in this group. Data on consecutive patients with DLBCL aged ≥70 years treated with 1 to 8 cycles of full or attenuated R-CHOP were retrospectively collected across 10 UK centers (2009-2019). Patients were followed up from starting R-CHOP for a minimum of 6 months and censored at 18 months; at last follow-up if <18 months; or at progression or death. Of 877 patients identified, 148 were excluded: 121 had progression or died before 6 months; 23 had follow-up <6 months. Across 729 remaining patients, the median age was 77 years, and 68% had an Eastern Cooperative Oncology Group performance status of 0 to 1. Eighty-one fractures occurred within 18 months of follow-up; 42 were symptomatic, including 30 requiring hospital attendance or admission. The cumulative fracture incidence was 6.2% (95% confidence interval [CI], 4.7-8.2) at 6 months; 9.7% (95% CI, 7.8-12.1) at 12 months; and 11.4% (95% CI, 9.3-14.0) at 18 months. Multivariate analysis identified a predisposing history (osteoporosis, osteopenia, prior fracture, and rheumatoid arthritis [RhA]), DLBCL bone involvement at baseline, and receipt of prephase steroids as independent risk factors for fracture. There is a clinically relevant fracture risk and significant associated morbidity in older patients receiving R-CHOP. Careful attention to bone health is warranted in older patients receiving R-CHOP. Randomized studies are required to better define the most effective strategies to reduce fracture risk.

Depression, Quality of Life, and Self-Esteem of Moroccan Postmenopausal Women with Osteoporosis before the Occurrence of Fractures

Objectives

Previous researches have investigated depression in postmenopausal women (PMW) with osteoporosis and fractures, but little is known regarding Moroccan PMW without fractures. We investigated depression prevalence and severity in Moroccan PMW with osteoporosis without fractures and its relationship with quality of life (QoL) and physical and psychological state.

Methods

This cross-sectional study enrolled 100 PMW with osteoporosis without fractures. Depressive symptoms, QoL, self-esteem, and fatigue were evaluated using the Patient Health Questionnaire-9 (PHQ-9), Arabic version of ECOS-16 questionnaire, Rosenberg self-esteem scale, and Arabic version of the Multidimensional Assessment of Fatigue scale, respectively. A questionnaire including sociodemographic factors, bone density features, pain intensity, and sleep disturbance was completed.

Results

Overall, 58% patients suffered from depression and 55% from pain (63.8% depressed women vs. 42.9% nondepressed patients; P = 0.03). Bone mineral density, lumbar spine T-score, ECOS-16, and self-esteem in depressed and nondepressed women were 0.791 (0.738–0.840) vs. 0.835 (0.790–0.866); −3.25 (−3.8 to −2.875) vs. −2.9 (−3.425 to −2.700), P = 0.02; 2.338 ± 0.605 vs. 1.638 ± 0.455; and 13.517 ± 5.487 vs. 18.404 ± 5.771, P < 0.0001, respectively. Depression severity correlated with pain, QoL, self-esteem, and fatigue (r = 0.367, r = −0.390, r = −0.390, and r = 0.369, respectively; P < 0.0001) as well as lumbar spine bone mineral density and T-score (r = −0.258 and r = −0.255, respectively; P = 0.01). Multiple linear regression analysis revealed impaired QoL (β = 0.526; P < 0.0001), fatigue (β = 0.177; P = 0.02), and lower self-esteem (β = −2.170; P = 0.005) as the strongest risk factors of depression.

Conclusions

Our study shows that even without fractures, Moroccan PMW with osteoporosis suffered from depression, pain, impaired QoL, and lower self-esteem.

Vertebroplasty with posterior spinal fusion for osteoporotic vertebral fracture using computer-assisted rod contouring system: A new minimally invasive technique

•

Surgical treatment of osteoporotic vertebral fracture (OVF) is challenging.

•

A new minimally invasive technique of posterior spinal fusion was performed for OVF.

•

This technique would be beneficial for elderly or immunocompromised patients.

Introduction

Surgical treatment of osteoporotic vertebral fracture (OVF) has been challenging for spine surgeons, because there are potential risks of instrumentation failure; such as screw loosening, loss of correction, or pseudarthrosis, due to bone fragility in elderly patients with several comorbidities.

Presentation of case

A 68-year-old female presented with a severe low back pain and bilateral thigh pain. She had a history of systemic scleroderma, which was complicated by interstitial lung disease. Although she initially underwent non-surgical treatment with bracing for 7 months, her symptoms had progressively deteriorated, and her radiographs showed non-union at L1 and progressive kyphotic deformity at the thoracolumbar spine. Because an anterior approach was inadvisable due to interstitial lung disease, vertebroplasty with posterior spinal fusion was performed using percutaneous pedicle screws (PPS) at the upper most and lowest instrumented vertebra combined with sublaminar taping and computer-assisted rod contouring system. Good bony union was achieved with no screw loosening at 1-year follow-up.

Discussion

Various surgical procedures have been applied according to the fracture type or medical condition of the patient. Minimally invasive posterior spinal fusion would be a less invasive approach in patients with poor medical condition. PPS can prevent the excessive dissection of paravertebral muscles, and this is especially advantageous at the proximal and distal end of long constructs. A recent computer-assisted rod contouring system accurately matches each screw head resulting in reduced strength of the screw-bone interface.

Conclusion

This technique would be beneficial in the elderly or immunocompromised patients with OVF.

Unknown osteoporosis in older patients admitted to post-acute rehabilitation

BACKGROUND

Osteoporotic fractures are associated with increased morbidity, mortality, and increased health care use. As the number of older adults increases, identifying those at increased risk for osteoporotic fractures has become of utmost importance to providing them with preventive and therapeutic interventions.

AIMS

To determine the prevalence of unknown clinical and densitometric osteoporosis and to investigate the performance of different diagnostic strategies for osteoporosis in elderly patients admitted to rehabilitation.

METHOD

This is an observational study. Eligible participants were older adults admitted to rehabilitation in an academic hospital in Switzerland over an 11-month period. Patients with previously unknown osteoporosis underwent dual-energy X-ray absorptiometry (DXA), vertebral fracture assessment (VFA), and history review for past fractures.

RESULTS

Complete assessment was available for 252 patients. Previously undiagnosed osteoporosis was identified in 62.3% of these patients, a proportion that was higher among women (71.5%) than men (44.8%). DXA proved most sensitive, followed by VFA and history review. Results differed across gender: DXA remained the most sensitive single test among women, but VFA proved most sensitive in men. The best test to combine with history review was DXA in women (detection increasing from 47.5 to 93.2%) and VFA in men (detection increasing from 35.9 to 84.6%).

CONCLUSIONS

Prevalence of previously unknown osteoporosis appears very high in elderly patients admitted to post-acute rehabilitation. The combination of history review of previous fractures with DXA in women and with VFA in men appears the best two-step strategy to improving detection of osteoporosis in this population.

The incidence and risk factors for adjacent vertebral fractures in community-dwelling people with prevalent vertebral fracture: the 3rd and 4th survey of the ROAD study

In this 3-year follow-up study of 66 community-dwelling adults with severely deformed vertebral fractures, the annual incidence of adjacent vertebral fracture (AVF) was 6.1%/year. Lower bone mineral density at the femoral neck and spinopelvic malalignment were risk factors for AVF.

PURPOSE

This study aimed to clarify the incidence and risk factors of adjacent vertebral fractures (AVFs)-fractures adjacent to a prevalent vertebral fracture (VF)-using an established population-based cohort from the ROAD study.

METHODS

Among the 1213 participants who underwent whole-spine radiography in ROAD's third (2012-2013, the baseline) and fourth surveys (2015-2016, the follow-up), 66 (12 men, 54 women) had at least one VF at the baseline. VF and AVF were determined radiographically using Genant's semi-quantitative (SQ) method, where VF was SQ ≥ 2 and AVF was a one-level cranial or caudal vertebra with an SQ grade one or more higher at the follow-up. An interviewer-administered questionnaire was applied, and anthropometric measurements and bone mineral density (BMD) measurements at the lumbar spine and femoral neck were performed. Sagittal imbalance of the spine was defined as a mismatch between pelvic incidence and lumbar lordosis (PI-LL) of > 20°. Multivariate logistic regression analyses were performed to identify risk factors for AVF.

RESULTS

AVF occurred in 12 participants (1 man, 11 women). The annual incidence of AVF was estimated at 6.1%/year. Logistic regression analyses revealed that lower BMD at the femoral neck and PI-LL > 20° were risk factors for AVF.

CONCLUSIONS

The annual incidence of AVF in a general population with prevalent VF was 6.1%/year. In addition, lower BMD at the femoral neck and PI-LL > 20° were risk factors for AVF.

The epidemiology of osteoporosis

INTRODUCTION

With a worldwide ageing population, the importance of the prevention and management of osteoporotic fragility fractures is increasing over time. In this review, we discuss in detail the epidemiology of fragility fractures, how this is shaped by pharmacological interventions and how novel screening programmes can reduce the clinical and economic burden of osteoporotic fractures.

SOURCES OF DATA

PubMed and Google Scholar were searched using various combinations of the keywords 'osteoporosis', 'epidemiology', 'fracture', 'screening', `FRAX' and 'SCOOP'.

AREAS OF AGREEMENT

The economic burden of osteoporosis-related fracture is significant, costing approximately $17.9 and £4 billion per annum in the USA and UK.

AREAS OF CONTROVERSY

Risk calculators such as the web-based FRAX® algorithm have enabled assessment of an individual's fracture risk using clinical risk factors, with only partial consideration of bone mineral density (BMD).

GROWING POINTS

As with all new interventions, we await the results of long-term use of osteoporosis screening algorithms and how these can be refined and incorporated into clinical practice.

AREAS TIMELY FOR DEVELOPING RESEARCH

Despite advances in osteoporosis screening, a minority of men and women at high fracture risk worldwide receive treatment. The economic and societal burden caused by osteoporosis is a clear motivation for improving the screening and management of osteoporosis worldwide.

Quality of Life among Iranian Postmenopausal Women: A Systematic Review and Meta-Analysis

Menopause can cause mental, physical, vasomotor, and sexual symptoms and problems, which negatively affect the quality of life (QOL). The aim of this study was to systematically evaluate QOL among Iranian postmenopausal women. This systematic review was conducted on cross-sectional studies that were published between 2000 and 2018. An online search to find studies published in English or Persian was conducted in the databases of Web of Science, PubMed, ScienceDirect, Scopus, Google Scholar, Scientific Information Database, Magiran, and IranMedex. Search key terms were "quality of life", "menopause", and "Iran". Fourteen studies were eligible for this study. The Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist was used for quality appraisal. The mean and standard deviation of QOL and its domains were extracted from the selected studies. Study data were analyzed using the Review Manager (v. 5.0) and the STATA (v. 12.0) software. The mean of total QOL among 3413 postmenopausal women was 57.89±12.8 (in the possible range of 0–174). The means of its vasomotor, psychosocial, physical, and sexual domains were 7.86±2.14, 19.43±2.05, 40.58±3.33, and 6.71±1.77, respectively. The QOL among Iranian postmenopausal women is nearly higher than the moderate level. The lowest and the highest levels of QOL are related to the physical and sexual domains, respectively. Health authorities need to develop educational interventions to promote postmenopausal women’s QOL, particularly in the physical domain.

The prevalence and incidence of vertebral fractures in end-stage renal disease and the role of parathyroid hormone

The risk of vertebral fracture is unclear in end-stage renal disease. We report a high vertebral fracture prevalence and incidence in transplantation-eligible patients on dialysis, suggesting that these patients may benefit from radiographic screening for vertebral fractures. Parathyroid hormone had a U-shaped association with vertebral fracture risk.

INTRODUCTION

Vertebral fractures are often overlooked, but even undiagnosed vertebral fractures negatively impact physical functioning, quality of life, and mortality. The risk of vertebral fractures in end-stage renal disease (ESRD) patients is unclear, and parathyroid hormone (PTH) might play a role in the development of vertebral fractures. We therefore determined vertebral fracture prevalence and incidence in ESRD patients and assessed associations of vertebral trabecular bone mineral density (BMD) and PTH with vertebral fracture.

METHODS

In 146 transplantation-eligible patients on dialysis, we determined vertebral fractures on lateral chest radiographs, which image the thoracic and upper lumbar spine. We determined incident vertebral fractures in 70 patients with follow-up radiographs (23 received a kidney transplant) after median 1.8 years. Vertebral trabecular BMD was measured with computed tomography, and PTH measured with 2-site immunoassays, categorized in tertiles with the middle tertile as reference. We used Poisson regression to assess associations of vertebral trabecular BMD and PTH with vertebral fracture.

RESULTS

Mean age of the study population was 52 ± 13 years, and 98 (67%) were male. Median dialysis duration was 26 (IQR 13-55) months. Vertebral fractures were present in 50/146 patients (34%) and incident vertebral fractures occurred in 20/70 patients (29%). Vertebral trabecular BMD was not associated with vertebral fracture prevalence (relative risk 0.97, 95% CI 0.89 to 1.04). For the lowest PTH tertile (< 11 pmol/L), the relative risk of vertebral fracture was greater although not significant (2.28, 95% CI 0.97 to 5.97) and was significantly greater for the highest PTH tertile (≥ 30 pmol/L; 2.82, 95% CI 1.22 to 7.27) after adjustment for potential confounders.

CONCLUSIONS

The prevalence and incidence of vertebral fractures is high even in relatively young and healthy ESRD patients. Vertebral trabecular BMD is not associated with vertebral fracture, and the association of PTH with vertebral fracture risk appears U-shaped. Nevertheless, our study did not measure vertebral BMD using DXA and assessed vertebral fractures using lateral chest radiographs and not spine radiographs.

Neglected bodily senses in women living with vertebral fracture: a focus group study

OBJECTIVE

Older women are at particular risk of osteoporosis. Among women with osteoporosis, fractures of the vertebra (vertebral fracture) are common, hard to detect and associated with risk of further fracture. Identifying vertebral fracture in a timely manner allows instigation of preventive measures to reduce the risk of further fracture. Although detection of vertebral fracture requires spinal radiograph, many women do not receive referral. To begin development of a screening tool to identify women in need of referral we undertook a qualitative study to characterize women's experiences of vertebral fracture, using Eccleston's 'Ten Neglected Bodily Senses'.

METHODS

Four qualitative focus groups were conducted with women who had been diagnosed with vertebral fracture (n = 19, age 60-91 years). Data were audio-recorded, transcribed and analysed thematically using the 'Ten Neglected Bodily Senses'.

RESULTS

Women's experiences of vertebral fractures related to seven senses: pain, movement, fatigue, balance, pressure, appetite and breathing. Pain was the dominant sense and all participants explained how pain increased with activity, reaching a crescendo, and described strategies to minimize this disruption. Most participants had become physically shorter, making some feel 'squashed', putting pressure on other body parts. Some described appetite loss or a sense of restricted breathing. Participants experienced a sense of being 'pulled' forwards, impacting on balance and exacerbating fear of falling.

CONCLUSION

The study found senses that have not been previously described in the experiences of women with vertebral fracture. These will be used to inform the design of a new screening tool for use in primary care.

Lupus nephritis

Lupus nephritis (LN) is a form of glomerulonephritis that constitutes one of the most severe organ manifestations of the autoimmune disease systemic lupus erythematosus (SLE). Most patients with SLE who develop LN do so within 5 years of an SLE diagnosis and, in many cases, LN is the presenting manifestation resulting in the diagnosis of SLE. Understanding of the genetic and pathogenetic basis of LN has improved substantially over the past few decades. Treatment of LN usually involves immunosuppressive therapy, typically with mycophenolate mofetil or cyclophosphamide and with glucocorticoids, although these treatments are not uniformly effective. Despite increased knowledge of disease pathogenesis and improved treatment options, LN remains a substantial cause of morbidity and death among patients with SLE. Within 10 years of an initial SLE diagnosis, 5-20% of patients with LN develop end-stage kidney disease, and the multiple comorbidities associated with immunosuppressive treatment, including infections, osteoporosis and cardiovascular and reproductive effects, remain a concern. Clearly, early and accurate diagnosis of LN and prompt initiation of therapy are of vital importance to improve outcomes in patients with SLE.

High bone marrow fat in patients with Cushing's syndrome and vertebral fractures

PURPOSE

The evaluation of skeletal fragility in Cushing's syndrome (CS) is a clinical challenge, since dual-energy X-ray absorptiometry (DXA) does not capture abnormalities in bone microstructure induced by glucocorticoid excess. Hypercortisolism was shown to increase bone marrow adiposity, but it is still unknown whether high bone marrow fat (BMF) as measured by vertebral magnetic resonance spectroscopy may predict fracture risk in this clinical setting. In this cross-sectional study, we evaluated the association between BMF and vertebral fractures (VFs) in patients with CS.

METHODS

Twenty patients (5 M, age 44 ± 13 years) with active CS were evaluated for morphometric VFs, lumbar spine BMF, and bone mineral density (BMD). Fifteen healthy volunteers (4 M, age 43 ± 12 years) acted as control group for BMF evaluation.

RESULTS

BMF was significantly higher in CS patients vs. controls (52.0% vs. 27.0%, p < 0.01), and was directly correlated with patients' age (p = 0.03), 24-hours urine-free cortisol (p = 0.03), midnight serum cortisol (p = 0.02), and serum CTX (p = 0.01). Patients with VFs (13 cases) showed significantly higher BMF vs. patients without VFs (65.0% vs. 24.0%, p = 0.03). Fractured patients with either normal BMD or osteopenia showed comparable BMF to fractured patients with either osteoporosis or low BMD for age (p = 0.71). When the analysis was restricted to patients with normal BMD or osteopenia, VFs were still significantly associated with higher BMF (p = 0.05).

CONCLUSIONS

This study provides a first evidence that vertebral adiposity may be a marker of hypercortisolism-induced skeletal fragility and measurement of spine BMF could have a role in the diagnostic work-up for the assessment of fracture risk in CS.

Associations between health-related quality of life, physical function and pain in older women with osteoporosis and vertebral fracture

Background

Osteoporosis and vertebral fractures represent a major health burden worldwide, and the prevalence of osteoporosis is expected to increase as the world’s population ages. Suffering from vertebral fracture has a substantial impact on the individual’s health-related quality of life (HRQoL), physical function and pain. Complex health challenges experienced by older people with osteoporosis and vertebral fractures call for identification of factors that may influence HRQoL, as some of these factors may be modifiable. The objective is to examine the independent associations between HRQoL, physical function and pain in older women with osteoporosis and vertebral fracture.

Methods

This study has a cross-sectional design, using data from 149 home-dwelling Norwegian women with osteoporosis and vertebral fracture, aged 65+. Data on HRQoL (Short Form 36 (SF-36), Quality of Life Questionnaire of the European Foundation for Osteoporosis (QUALEFFO-41)), physical function (walking speed, balance and strength), pain, as well as sociodemographic information were collected. Simple linear regression analyses were conducted and multivariable regression models were fitted to investigate the associations.

Results

Lower levels of HRQoL were significantly associated with lower levels of physical function, measured by walking speed, and higher levels of pain. Pain was significantly associated with all of the subscales in SF-36, with the exception of Mental Health and Mental Component Score, and all the subscales of QUALEFFO-41. Walking speed was significantly associated with 5 of 8 subscales of SF-36 (except Bodily Pain, Vitality, Mental Health and Mental Component Score), and with 4 of 6 subscales of QUALEFFO-41 (except Score Pain and Mood).

Conclusion

This study shows that pain and walking speed were, independently of one another, associated with HRQoL in older women with osteoporosis and vertebral fracture. These findings can inform clinicians and health managers about the importance of pain management and exercise interventions in health care for this group. Future research should address interventions targeting both physical function and pain with HRQoL as an outcome.

Impact of fractures on quality of life in patients with osteoporosis: a US cross-sectional survey

Objective: To evaluate the impact of osteoporosis-related fractures on health-related quality of life (HRQoL). Methods: Data were obtained from the 2016 Adelphi US Osteoporosis Disease Specific Programme™, a cross-sectional survey of physicians and their male and female patients with osteoporosis. Patient-reported outcomes (PRO) measures included the European Quality of Life 5 Domains (EQ-5D), European Quality of Life Visual Analog Scale (EQ-VAS), and Osteoporosis Assessment Questionnaire short-version (OPAQ-SV; physical, emotional, and symptom domains). Associations between PRO scores and the number and site of fractures were evaluated using ANOVA. Multivariate analyses were conducted using linear regression. Results: Physicians provided records for 1848 patients with osteoporosis. Of these, 981 (53.1%) completed the patient survey, data for the number of fractures were available for 935/981 (95.3%), and 185/935 (19.8%) had a history of fracture. Experiencing fractures significantly influenced scores on all PRO measures (p < .0001). Hip and spine fractures were associated with the greatest reduction in most PRO scores. The number of fractures, age, body mass index, and Charlson Comorbidity Index (CCI) were significantly associated with PRO measures (p < .05) in multivariate analyses. In patients with a fracture, fracture site, CCI, gender (EQ-5D and EQ-VAS), and age (OPAQ-SV physical only) were significantly associated with PRO measures. Conclusions: In patients with osteoporosis, fractures are associated with lower HRQoL and lower overall health status. Fracture history, fracture site, age, and comorbidity burden significantly influence HRQoL in individuals with osteoporosis. These data suggest the need for interventions to reduce the risk of fractures in patients with osteoporosis.

Differences in prevalence and associated factors between mild and severe vertebral fractures in Japanese men and women: the third survey of the ROAD study

Vertebral fracture (VF) is a common osteoporotic fracture, while its epidemiology varies according to regions and ethnicities, little is known about it in Japan. Using whole-spine radiographs from a population-based cohort study, the Research on Osteoarthritis/Osteoporosis Against Disability study 3rd survey performed in 2012-2013, we estimated the sex- and age-specific prevalence of VF in the Japanese. Genant's semiquantitative method (SQ) was used to define VF; SQ ≥ 1 as VF, SQ = 1 as mild VF, SQ≥ 2 as severe VF. We also revealed accurate site-specific prevalence, and associated factors with mild and severe VF. The participants were 506 men [mean age 66.3 years, standard deviation (SD):13.0] and 1038 women (mean age 65.3 years, SD: 12.6). The prevalence of VF in participants aged under 40, in their 40s, 50s, 60s, 70s, and ≥ 80 years was 17.4, 7.9, 18.5, 25.6, 26.3, and 41.5%, respectively, in men, and 2.9%, 2.4%, 7,3, 10.3, 27.1, and 53.0%, respectively, in women. Men had a significantly higher prevalence of mild VF (21.2%) than women (10.0%, p < 0.001); whereas, severe VF was significantly more prevalent in women (9.1%) than in men (4.7%, p = 0.003). VF was distributed with 2 peaks regarding site; one large peak at the thoracolumbar region, and another at the middle thoracic lesion. Low back pain and decreased walking ability were independently associated with severe VF, but not with mild VF, after adjustment for participant characteristics. Decreased walking ability was associated with multiple VFs in women, but not in men.

Simple methods for the estimation and sensitivity analysis of principal strata effects using marginal structural models: Application to a bone fracture prevention trial

In randomized clinical trials, it is often of interest to estimate the effect of treatment on quality of life (QOL), in addition to those on the event itself. When an event occurs in some patients prior to QOL score assessment, investigators may compare QOL scores between patient subgroups defined by the event after randomization. However, owing to postrandomization selection bias, this analysis can mislead investigators about treatment efficacy and result in paradoxical findings. The recent Japanese Osteoporosis Intervention Trial (JOINT-02), which compared the benefits of a combination therapy for fracture prevention with those of a monotherapy, exemplifies the case in point; the average QOL score was higher in the combination therapy arm for the unfractured subgroup but was lower for the fractured subgroup. To address this issue, principal strata effects (PSEs), which are treatment effects estimated within subgroups of individuals stratified by potential intermediate variable, have been discussed in the literature. In this paper, we describe a simple procedure for estimating the PSEs using marginal structural models. This procedure utilizes SAS code for the estimation. In addition, we present a simple sensitivity analysis method for examining the resulting estimates. The analyses of JOINT-02 data using these methods revealed that QOL scores were higher in the combination therapy arm than in the monotherapy arm for both subgroups.

Exercise for improving outcomes after osteoporotic vertebral fracture

BACKGROUND

Vertebral fractures are associated with increased morbidity (e.g. pain, reduced quality of life) and mortality. Therapeutic exercise is a non-pharmacological conservative treatment that is often recommended for patients with vertebral fractures to reduce pain and restore functional movement. This is an update of a Cochrane Review first published in 2013.

OBJECTIVES

To assess the effects (benefits and harms) of exercise intervention of four weeks or greater (alone or as part of a physical therapy intervention) versus non-exercise/non-active physical therapy intervention, no intervention or placebo among adults with a history of vertebral fractures on incident fragility fractures of the hip, vertebra or other sites. Our secondary objectives were to evaluate the effects of exercise on the following outcomes: falls, pain, physical performance, health-related quality of life (disease-specific and generic), and adverse events.

SEARCH METHODS

We searched the following databases until November 2017: the Cochrane Library (Issue 11 of 12), MEDLINE (from 2005), Embase (from 1988), CINAHL (Cumulative Index to Nursing and Allied Health Literature, from 1982), AMED (from 1985), and PEDro (Physiotherapy Evidence Database, from 1929). Ongoing/recently completed trials were identified by searching the World Health Organization International Clinical Trials Registry Platform and ClinicalTrials.gov. Conference proceedings were searched via ISI and SCOPUS, and targeted searches of proceedings of the American Congress of Rehabilitation Medicine and American Society for Bone and Mineral Research. Search terms or MeSH headings included terms such as vertebral fracture AND exercise OR physical therapy. For this update, the search results were limited from 2011 onward.

SELECTION CRITERIA

We included all randomized controlled trials and quasi-randomized trials comparing exercise or active physical therapy interventions with placebo/non-exercise/non-active physical therapy interventions or no intervention implemented in individuals with a history of vertebral fracture.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected trials and extracted data using a pre-tested data extraction form. Disagreements were resolved by consensus, or third-party adjudication. We used Cochrane's tool for assessing risk of bias to evaluate each study. Studies were grouped according to duration of follow-up (i.e. a) 4-12 weeks; b) 16-24 weeks; c) 52 weeks); a study could be represented in more than one group depending on the number of follow-up assessments. For dichotomous data, we reported risk ratios (RR) and corresponding 95% confidence intervals (95% CI). For continuous data, we reported mean differences (MD) of the change from baseline and 95% CI. Data were pooled for Timed Up and Go test, self-reported physical function measured by the QUALEFFO-41 physical function subscale score (scale of zero to 100; lower scores indicate better self-reported physical function), and disease-specific quality of life measured by the QUALEFFO-41 total score (scale of zero to 100; lower scores indicate better quality of life) at 12 weeks using a fixed-effect model.

MAIN RESULTS

Nine trials (n = 749, 68 male participants; two new trials in this review update) were included. Substantial variability across the trials prevented any meaningful pooling of data for most outcomes. Risk of bias across all studies was variable; low risk across most domains in four studies, and unclear/high risk in most domains for five studies. Performance bias and blinding of subjective outcome assessment were almost all high risk of bias.One trial reported no between-group difference in favor of the effect of exercise on incident fragility fractures after 52 weeks (RR 0.54, 95% CI 0.17 to 1.71; very low-quality evidence with control: 184 per 1000 and exercise: 100 per 1000, 95% CI 31 to 315; absolute difference: 8%, 95% CI 2 to 30). One trial reported no between-group difference in favor of the effect of exercise on incident falls after 52 weeks (RR 1.06, 95% CI 0.53 to 2.10; very low-quality evidence with control: 262 per 1000 and exercise: 277 per 1000; 95% CI 139 to 550; absolute difference: 2%, 95% CI -12 to 29). These findings should be interpreted with caution because of the very serious risk of bias in these studies and the small sample sizes resulting in imprecise estimates.We are uncertain that exercise could improve pain, self-reported physical function, and disease-specific quality of life, because certain studies showed no evidence of clinically important differences for these outcomes. Pooled analyses revealed a small between-group difference in favor of exercise for Timed Up and Go (MD -1.13 seconds, 95% CI -1.85 to -0.42; studies = 2), which did not change following a sensitivity analysis (MD -1.09 seconds, 95% CI -1.78 to -0.40; studies = 3; moderate-quality evidence). Exercise improved QUALEFFO-41 physical function score (MD -2.84 points, 95% CI -5.57 to -0.11; studies = 2; very low-quality evidence) and QUALEFFO-41 total score (MD -3.24 points, 95% CI -6.05 to -0.43; studies = 2; very low-quality evidence), yet it is unlikely that we observed any clinically important differences. Three trials reported four adverse events related to the exercise intervention (costal cartilage fracture, rib fracture, knee pain, irritation to tape, very low-quality evidence).

AUTHORS' CONCLUSIONS

In conclusion, we do not have sufficient evidence to determine the effects of exercise on incident fractures, falls or adverse events. Our updated review found moderate-quality evidence that exercise probably improves physical performance, specifically Timed Up and Go test, in individuals with vertebral fracture (downgraded due to study limitations). However, a one-second improvement in Timed Up and Go is not a clinically important improvement. Although individual trials did report benefits for some pain and disease-specific quality of life outcomes, the findings do not represent clinically meaningful improvements and should be interpreted with caution given the very low-quality evidence due to inconsistent findings, study limitations and imprecise estimates. The small number of trials and variability across trials limited our ability to pool outcomes or make conclusions. Evidence regarding the effects of exercise after vertebral fracture in men is scarce. A high-quality randomized trial is needed to inform safety and effectiveness of exercise to lower incidence of fracture and falls and to improve patient-centered outcomes (pain, function) for individuals with vertebral fractures (minimal sample size required is approximately 2500 untreated participants or 4400 participants if taking anti-osteoporosis therapy).

Treatment of Glucocorticoid-Induced Osteoporosis with Bisphosphonates Alone, Vitamin D Alone or a Combination Treatment in Eastern Asians: A Meta-Analysis

Background:

Glucocorticoid (GC)-induced osteoporosis and fractures have become a serious problem for Eastern Asians. Bisphosphonates (BPs), vitamin D and a combination treatment are effective methods to prevent and treat GC-induced osteoporosis.

Objective:

The study aimed to compare the efficacy of BPs, vitamin D and a combination treatment for preventing and managing GC-induced osteoporosis in Eastern Asians.

Methods:

A comprehensive search in the PubMed, EMBASE, Web of Science and Cochrane CENTRAL databases was undertaken for randomized controlled trials (RCTs) on the effect of BPs, vitamin D and the combination treatment on GCs-induced osteoporosis in Eastern Asian populations. Primary outcome measures were the change in bone mineral density (BMD) and bone turnover markers. The final search was performed in March 2019.

Results:

Nine RCTs were included. A total of 545 patients met the inclusion criteria. Compared with vitamin D, BPs and the combination treatment significantly alleviated osteoporosis of the spine and femoral neck in Eastern Asians with GC-induced osteoporosis. At the same time, the change in serum bone-specific alkaline phosphatase (BAP) and serum C-telopeptide of type I collagen (CTX) levels was observed to be significantly less with BPs and the combination treatment with vitamin D alone. No significant difference was found between BPs and the combination treatment in the markers mentioned above.

Conclusion:

Compared with vitamin D alone, BPs alone and the combination treatment were significantly effective on Eastern Asians with GC-induced osteoporosis. Compared with the combination treatment, BPs alone were observed to be effective enough to increase the BMDs of the spine and femoral neck on both sides and thus prevent GC-induced osteoporosis in Eastern Asians.

Relationship Between L4/5 Lumbar Multifidus Cross-Sectional Area Ratio and Fall Risk in Older Adults with Lumbar Spinal Stenosis: A Retrospective Study

Various factors, including spinal deformities and trunk muscle atrophy, greatly affect the fall risk among older adults with lumbar spinal stenosis (LSS). However, the etiology of falls in older adults with degenerative LSS and trunk muscle atrophy is poorly understood. We investigated the association between trunk muscle atrophy and falls in older LSS patients. This retrospective study included 99 hospitalized older adults with LSS. Participants completed self-reported fall score questionnaires and were divided into the fall risk (n = 30) and non-fall risk (n = 69) groups. The patients' low back pain visual analog scale score, Geriatric Depression Scale score, sagittal vertical axis, L4/5 lumbar multifidus cross-sectional area ratio (LMCSAR), and center of pressure (COP) values during quiet standing were evaluated. The fall risk group had a lower L4/5 LMCSAR (p = 0.002) and increased COP excursion (p = 0.034) than the non-fall risk group. No significant differences were observed in the other measured variables between the two groups. The L4/5 LMCSAR (p < 0.001) and COP (p = 0.024) were related to fall risk and may be useful in fall risk assessment in such populations. Strategies aimed at enhancing controlled lumbar segmental motion and improving trunk muscle stability or mass may decrease the fall risk in this cohort.

Osteoporosis and vertebral fracture are associated with deterioration of activities of daily living and quality of life in patients with type 2 diabetes mellitus

Patients with type 2 diabetes mellitus (T2DM) have an increased risk of fragility fracture. However, whether diabetes-related osteoporosis independently contributes to the deterioration of activities of daily living (ADLs) and quality of life (QOL) is unclear. This cross-sectional study investigated the association between osteoporosis, ADLs, and QOL in 309 patients with T2DM. ADLs and QOL were assessed using Barthel Index (BI) and a SF-36 questionnaire. Multiple logistic regression analyses adjusted for age, gender, T2DM duration, body mass index, hemoglobin A1c, estimated GFR, diabetic neuropathy, retinopathy, nephropathy, cardiovascular disease, cerebrovascular disease, peripheral artery disease, and anti-diabetic treatments were conducted. The number of patients with osteoporosis or vertebral fracture was 166 (53.7%) and 118 (38.2%), respectively. Osteoporosis was significantly associated with lower general health (GH), social functioning (SF), and role emotional (RE) (OR 2.56, 1.79, and 1.92, respectively; all p values < 0.05 at least) and marginally associated with lower BI (OR 2.39, p = 0.068). Moreover, the presence of vertebral fracture grade 2 or 3 was significantly associated with lower BI, bodily pain (BP), GH, vitality, SF, and RE (OR 2.58, 2.01, 3.64, 1.99, 2.18, and 1.97, respectively; all p values < 0.05 at least). Osteoporosis and severe vertebral fracture were associated with the deterioration of ADLs and QOL independently of other diabetic complications. Therefore, the management of diabetes-related osteoporosis is an important strategy to avoid the deterioration of ADLs and QOL in T2DM.

Surgical Treatment of Osteoporotic Vertebral Fracture with Neurological Deficit-A Nationwide Multicenter Study in Japan

Introduction

The prevalence of patients with osteoporosis continues to increase in aging societies, including Japan. The first choice for managing osteoporotic vertebral compression fracture (OVF) is conservative treatment. Failure in conservative treatment for OVF may lead to non-union or vertebral collapse, resulting in neurological deficit and subsequently requiring surgical intervention. This multicenter nationwide study in Japan was conducted to comprehensively understand the outcomes of surgical treatments for OVF non-union.

Methods

This multicenter, retrospective study included 403 patients (89 males, 314 females, mean age 73.8 ± 7.8 years, mean follow-up 3.9 ± 1.7 years) with neurological deficit due to vertebral collapse or non-union after OVF at T10-L5 who underwent fusion surgery with a minimum 1-year follow-up. Radiological and clinical outcomes at baseline and at the final follow-up (FU) were evaluated.

Results

OVF was present at a thoracolumbar junction such as T12 (124 patients) and L1 (117 patients). A majority of OVF occurred after a minor trauma, such as falling down (55.3%) or lifting objects (8.4%). Short segment fusion, including affected vertebra, was conducted (mean 4.0 ± 2.0 vertebrae) with 256.8 minutes of surgery and 676.1 g of blood loss. A posterior approach was employed in 86.6% of the patients, followed by a combined anterior and posterior (8.7%), and an anterior (4.7%) approach. Perioperative complications and implant failures were observed in 18.1% and 41.2%, respectively. VAS scores of low back pain (74.7 to 30.8 mm) and leg pain (56.8 to 20.7 mm) improved significantly at FU. Preoperatively, 52.6% of the patients were unable to walk and the rate of non-ambulatory patients decreased to 7.5% at FU.

Conclusions

This study demonstrated that substantial improvement in activity of daily living (ADL) was achieved by fusion surgery. Although there was a considerable rate of complications, fusion surgery is beneficial for elderly OVF patients with non-union.

Systemic Complications of Acromegaly and the Impact of the Current Treatment Landscape: An Update

Acromegaly is a chronic systemic disease with many complications and is associated with increased mortality when not adequately treated. Substantial advances in acromegaly treatment, as well as in the treatment of many of its complications, mainly diabetes mellitus, heart failure, and arterial hypertension, were achieved in the last decades. These developments allowed change in both prevalence and severity of some acromegaly complications and furthermore resulted in a reduction of mortality. Currently, mortality seems to be similar to the general population in adequately treated patients with acromegaly. In this review, we update the knowledge in complications of acromegaly and detail the effects of different acromegaly treatment options on these complications. Incidence of mortality, its correlation with GH (cumulative exposure vs last value), and IGF-I levels and the shift in the main cause of mortality in patients with acromegaly are also addressed.

An assessment of the relation between bone mineral density and clinic-demographic properties and life quality during postmenopausal period

OBJECTIVES

This study was conducted to assess the relation between bone mineral density (BMD) and clinic-demographic properties and life quality during postmenopausal period.

METHODS

The study group consisted of 172 postmenopausal women who applied to the physical therapy and rehabilitation outpatient clinic at a training and research hospital in Ankara, the capital of Turkey. The Survey Form, The 36-item Short Form Health Survey (SF-36) and the FRAX™ were used as data collection tools in this study.

RESULTS

The osteoporosis and osteopenia frequencies were respectively 28.5% and 42.4% in this study. The 10-year major osteoporotic fracture risk was 5.15% and the femur fracture risk was estimated as 0.9%. In this study, there was a positive and significant relation found between the L1⁢-⁢4 and FN T-score and SF-36 scale score average (p< 0.05). There was a significant relation between the body mass index and SF-36 subscale 'mental health' (p< 0.05). In this study, the most significant determinant of life quality was exhibited as the "L1⁢-⁢4 T-score" (β= 55.509, p= 0.000).

CONCLUSIONS

We determined that approximately one of every four women had osteoporosis and as the BMD dropped, the life quality of the women declined. Hence, we think that improving the awareness of health professionals working in this field is essential.

Cost-Effectiveness of Pharmacological Treatments for Osteoporosis Consistent with the Revised Economic Evaluation Guidelines for Canada

Introduction. Given the lack of independent analyses comparing numerous pharmacotherapies for osteoporosis, the study objective was to identify the optimal osteoporosis treatment based on a woman's age, fracture history, and ability to tolerate oral bisphosphonates adopting practices recommended in the recently revised Canadian guidelines. Methods. A cost utility analysis from the health care system perspective compared alendronate, etidronate, risedronate, zoledronate, denosumab, and no pharmacotherapy using a Markov model incorporating data on fracture risk and their associated costs, mortality, and disutility and treatment effect. Stratified analysis was conducted based on age, fracture history, and ability to tolerate oral bisphosphonates. Expected lifetime outcomes were obtained through probabilistic analysis with scenario analyses addressing methodological and structural uncertainty. Results. For women able to tolerate oral bisphosphonates, risedronate and etidronate were dominated. Compared to no therapy, alendronate was either dominant or was associated with a low incremental cost per QALY (quality-adjusted life years) gained (ICER)-less than CAN$3,751 based on age and fracture history. In comparison with alendronate, both zoledronate and denosumab were either dominated or associated with a high ICER-greater than CAN$660,000 per QALY. For women unable to tolerate bisphosphonates, dependent on age and fracture history, the ICER for zoledronate versus no therapy ranged from CAN$17,770 to CAN$94,365 per QALY. For all strata, denosumab was dominated by zoledronate or had an ICER greater than CAN$3.0 million. Scenario analyses found consistent findings. Conclusions. Based on a threshold of CAN$50,000 per QALY, alendronate is optimal for osteoporotic women who can tolerate oral bisphosphonates regardless of age or fracture history. For women unable to tolerate oral bisphosphonates, zoledronate is optimal for women with previous fracture or aged 80 to 84 or over 90 with no previous fracture.

Overwhelming Underuse of Bisphosphonates in French Nursing Home Residents After Proximal Femoral Fracture

OBJECTIVE

To evaluate the prescription of bisphosphonates in female nursing home residents aged 75 and older with a history of proximal femoral fracture.

DESIGN

Observational descriptive study, led in Brest, France, between June and August 2015.

SETTING

12 nursing homes in Brest, France.

PARTICIPANTS

Female nursing home residents, aged 75 and older, with a history of proximal femoral fracture were included. Exclusion criteria were contraindications to bisphosphonate treatment and residents restricted to bed and chair.

MEASUREMENTS

The primary endpoint was the evaluation of prescription of bisphosphonates at the time of the study. The secondary endpoints were to evaluate vitamin D supplementation and factors associated with bisphosphonate prescription.

RESULTS

12 of the 116 included residents (10.3 %) received bisphosphonates. 66.4 % received vitamin D supplementation.

CONCLUSION

Despite successive French and international recommendations, there is still a very important underuse of treatment by bisphosphonates in old institutionalized female patients with a very high risk of fracture.

Health-related quality of life in Romanian postmenopausal women with osteoporosis and fragility fractures

Objectives

Osteoporosis is a common skeletal disorder characterized by decreased bone mass and increased susceptibility to fractures, which are associated with pain and decrease in physical function, social function, and well-being, which are all aspects of quality of life (QoL). The purpose of this study was to evaluate the burden of osteoporosis and fragility fractures in Romanian postmenopausal women from Cluj County using the 36-Item Short Form Health Survey (SF-36) and Quality of life questionnaire of the European Foundation for Osteoporosis (QUALEFFO-41) questionnaires.

Materials and methods

An analytical cross-sectional study on 364 postmenopausal women was carried out between June 2016 and August 2017 in the Clinical Rehabilitation Hospital in Cluj-Napoca, Cluj County, Romania. Data were collected by interview and from the medical documents: clinical and demographic data, personal medical history, risk factors for osteoporosis, and bone mineral density at the lumbar spine and femur. The patients included in the study were asked to complete the Romanian versions of the SF-36 and QUALEFFO-41 questionnaires.

Results

Women with osteoporosis had significantly lower scores in the SF-36 domains (P<0.001) than healthy controls. In the osteoporosis group, a significant association was found in the SF-36 pain domain, where women with a history of fracture had higher scores (P=0.035). As for QUALEFFO-41, a statistical significance was found in the total score (P<0.05), revealing a significantly lower QoL in osteoporotic women with a history of fracture.

Conclusion

The SF-36 scores registered a loss of QoL in women with osteoporosis. The QUALEFFO-41 total score was significantly lower in the osteoporosis associated with fracture, revealing a lower health-related QoL in these patients.
