Influence of Ethnicity and Deprivation on Occurrence of Paget'S Disease in Greater Manchester, UK.

There is important variation in the occurrence of Paget's disease in different regions and populations. There are though few data concerning the occurrence of clinically diagnosed disease in black and ethnic minority groups in the United Kingdom (UK). We undertook an anonymised search using an integrated primary and secondary care-based database in Greater Manchester, covering a population of over 3 million people. We looked also among those with a first positive COVID test, the influence of Paget's disease on subsequent admission to hospital within 28 days. Within our database, there were 534,571 people aged 60 years and over alive on 1 January 2020. The majority were white (84%) with 4.7% identifying as Asian or Asian British, and 1.27% Black or Black British. There were 931 with clinically diagnosed Paget's disease. Overall prevalence in the greater Manchester area was 0.174%. Prevalence was higher in men than women (0.195 vs 0.155%). Compared to the prevalence of Paget's in whites (0.179%) the prevalence was lower among those identifying as Asian or Asian British (0.048%) and higher among those identifying as Black or Black British (0.344%). Prevalence increased with increasing deprivation. Clinically diagnosed Paget's disease is uncommon affecting 0.174% of men and women aged 60 or more years. Within Greater Manchester, it was more common in those identifying as Black or Black British and less common in those identifying as Asian or Asian British.

Hyponatremia, hypernatremia and impairment of functional, psychological and sexual domains.

OBJECTIVE: To determine the influence of serum sodium on physical, psychologic and sexual function. METHODS: This is a cross-sectional survey on 3340 community-dwelling men aged 40-79 years from a prospective cohort study in eight European countries, the European Male Ageing Study (EMAS). Participants filled-out the Short Form-36 (SF-36), the Physical Activity Scale for the Elderly (PASE), and the EMAS sexual function questionnaire. For all the analyses, serum sodium corrected for glycaemia ([Na+]G) was used. RESULTS: The relationship between [Na+]G and SF-36 physical function score (F = 3.99; p = 0.01), SF-36 mental health score (F = 7.69; p < 0.001), and PASE score (F = 14.95; p < 0.001) were best described by a quadratic equation, with worse scores for [Na+]G in either the lowest or the highest ends of the range. After dividing the sample into [Na+]G < 136 mmol/L (n = 81), 136-147 mmol/L (n = 3223) and > 147 mmol/L (n = 36), linear regression analyses with linear spline functions adjusted for confounders did not confirm these relationships. Similarly, erectile dysfunction and [Na+]G, were in a quadratic relationship (F = 9.00; p < 0.001). After adjusting for confounders, the linear regression with spline functions denoted a significantly worsened erectile function for increases in serum [Na+]G > 147 mmol/L (B = 0.15 [0.04;0.26], p < 0.01) but no relationship with [Na+]G < 136 mmol/L. Likewise, the relationship of [Na+]G with concerns about sexual dysfunction was confirmed only for men with serum [Na+]G > 147 mmol/L. CONCLUSIONS: This is the first study supporting an association between [Na+]G and sexual function. A worsening of erection and concerns about sexual function were observed for the highest values of [Na+]G, independently of other relevant factors.

The Impact of Frailty and Deprivation on the Likelihood of Receiving Primary Total Hip and Knee Arthroplasty among People with Hip and Knee Osteoarthritis.

BACKGROUND: Among people with hip and knee osteoarthritis (OA), increasing deprivation is associated with reduced likelihood of receiving hip and knee arthroplasty (THA, TKA). OBJECTIVES: To assess whether higher levels of frailty in the most deprived neighbourhoods explains the association between greater neighbourhood deprivation and reduced likelihood of receiving THA and TKA among people with hip and knee OA. DESIGN: Longitudinal cohort study. SETTING: Linked primary and secondary care electronic medical records and national mortality data. PARTICIPANTS: 104,913 individuals with incident hip OA and 216,420 with incident knee OA. MEASUREMENTS: Frailty was assessed using a frailty index and categorised as fit, mild, moderate, and severe frailty. Neighbourhood deprivation was assessed using the index of multiple deprivation (IMD). RESULTS: Compared to those in neighbourhoods in the least deprived quintile of IMD, those in neighbourhoods in the fourth and fifth quintile of IMD (most deprived), respectively, were less likely to receive THA, adjusted subhazard ratio (95% CI), 0.90 (0.87, 0.93) and 0.77 (0.74, 0.80), over a mean follow up of 4.4 years, with similar results for TKA. Higher levels of frailty at OA diagnosis were associated also with reduced likelihood of receiving THA and TKA. The association, however, between deprivation and likelihood of receiving THA and TKA could not be explained by increased levels of frailty among those living in the most deprived areas. CONCLUSIONS: Further work is needed to understand why those in the most deprived areas are less likely to receive THA and TKA.

Frailty among Older Adults and Its Distribution in England.

BACKGROUND: Information on the spatial distribution of the frail population is crucial to inform service planning in health and social care. OBJECTIVES: To estimate small-area frailty prevalence among older adults using survey data. To assess whether prevalence differs between urban, rural, coastal and inland areas of England. DESIGN: Using data from the English Longitudinal Study of Ageing (ELSA), ordinal logistic regression was used to predict the probability of frailty, according to age, sex and area deprivation. Probabilities were applied to demographic and economic information in 2020 population projections to estimate the district-level prevalence of frailty. RESULTS: The prevalence of frailty in adults aged 50+ (2020) in England was estimated to be 8.1 [95% CI 7.3-8.8]%. We found substantial geographic variation, with the prevalence of frailty varying by a factor of 4.0 [3.5-4.4] between the most and least frail areas. A higher prevalence of frailty was found for urban than rural areas, and coastal than inland areas. There are widespread geographic inequalities in healthy ageing in England, with older people in urban and coastal areas disproportionately frail relative to those in rural and inland areas. CONCLUSIONS: Interventions aimed at reducing inequalities in healthy ageing should be targeted at urban and coastal areas, where the greatest benefit may be achieved.

Long-term cost-effectiveness of screening for fracture risk in a UK primary care setting: the SCOOP study.

Community-based screening and treatment of women aged 70-85 years at high fracture risk reduced fractures; moreover, the screening programme was cost-saving. The results support a case for a screening programme of fracture risk in older women in the UK. INTRODUCTION: The SCOOP (screening for prevention of fractures in older women) randomized controlled trial investigated whether community-based screening could reduce fractures in women aged 70-85 years. The objective of this study was to estimate the long-term cost-effectiveness of screening for fracture risk in a UK primary care setting compared with usual management, based on the SCOOP study. METHODS: A health economic Markov model was used to predict the life-time consequences in terms of costs and quality of life of the screening programme compared with the control arm. The model was populated with costs related to drugs, administration and screening intervention derived from the SCOOP study. Fracture risk reduction in the screening arm compared with the usual management arm was derived from SCOOP. Modelled fracture risk corresponded to the risk observed in SCOOP. RESULTS: Screening of 1000 patients saved 9 hip fractures and 20 non-hip fractures over the remaining lifetime (mean 14 years) compared with usual management. In total, the screening arm saved costs (£286) and gained 0.015 QALYs/patient in comparison with usual management arm. CONCLUSIONS: This analysis suggests that a screening programme of fracture risk in older women in the UK would gain quality of life and life years, and reduce fracture costs to more than offset the cost of running the programme.

Screening for high hip fracture risk does not impact on falls risk: a post hoc analysis from the SCOOP study.

A reduction in hip fracture incidence following population screening might reflect the effectiveness of anti-osteoporosis therapy, behaviour change to reduce falls, or both. This post hoc analysis demonstrates that identifying high hip fracture risk by FRAX was not associated with any alteration in falls risk. INTRODUCTION: To investigate whether effectiveness of an osteoporosis screening programme to reduce hip fractures was mediated by modification of falls risk in the screening arm. METHODS: The SCOOP study recruited 12,483 women aged 70-85 years, individually randomised to a control (n = 6250) or screening (n = 6233) arm; in the latter, osteoporosis treatment was recommended to women at high risk of hip fracture, while the control arm received usual care. Falls were captured by self-reported questionnaire. We determined the influence of baseline risk factors on future falls, and then examined for differences in falls risk between the randomisation groups, particularly in those at high fracture risk. RESULTS: Women sustaining one or more falls were slightly older at baseline than those remaining falls free during follow-up (mean difference 0.70 years, 95%CI 0.55-0.85, p < 0.001). A higher FRAX 10-year probability of hip fracture was associated with increased likelihood of falling, with fall risk increasing by 1-2% for every 1% increase in hip fracture probability. However, falls risk factors were well balanced between the study arms and, importantly, there was no evidence of a difference in falls occurrence. In particular, there was no evidence of interaction (p = 0.18) between baseline FRAX hip fracture probabilities and falls risk in the two arms, consistent with no impact of screening on falls in women informed to be at high risk of hip fracture. CONCLUSION: Effectiveness of screening for high FRAX hip fracture probability to reduce hip fracture risk was not mediated by a reduction in falls.

Systematic screening using FRAX® leads to increased use of, and adherence to, anti-osteoporosis medications: an analysis of the UK SCOOP trial.

In the large community-based SCOOP trial, systematic fracture risk screening using FRAX® led to greater use of AOM and greater adherence, in women at high fracture risk, compared with usual care. INTRODUCTION: In the SCreening of Older wOmen for Prevention of fracture (SCOOP) trial, we investigated the effect of the screening intervention on subsequent long-term self-reported adherence to anti-osteoporosis medications (AOM). METHODS: SCOOP was a primary care-based UK multicentre trial of screening for fracture risk. A total of 12,483 women (70-85 years) were randomised to either usual NHS care, or assessment using the FRAX® tool ± dual-energy X-ray absorptiometry (DXA), with medication recommended for those found to be at high risk of hip fracture. Self-reported AOM use was obtained by postal questionnaires at 6, 12, 24, 36, 48 and 60 months. Analysis was limited to those who initiated AOM during follow-up. Logistic regression was used to explore baseline determinants of adherence (good ≥ 80%; poor < 80%). RESULTS: The mean (SD) age of participants was 75.6 (4.2) years, with 6233 randomised to screening and 6250 to the control group. Of those participants identified at high fracture risk in the screening group, 38.2% of those on treatment at 6 months were still treated at 60 months, whereas the corresponding figure for the control group was 21.6%. Older age was associated with poorer adherence (OR per year increase in age 0.96 [95% CI 0.93, 0.99], p = 0.01), whereas history of parental hip fracture was associated with greater rate adherence (OR 1.67 [95% CI 1.23, 2.26], p < 0.01). CONCLUSIONS: Systematic fracture risk screening using FRAX® leads to greater use of AOM and greater adherence, in women at high fracture risk, compared with usual care.

Association between Bone marrow lesions & synovitis and symptoms in symptomatic knee osteoarthritis.

OBJECTIVE: Bone marrow lesions (BMLs) on MRI are typically subchondral in location, however, a proportion occur at knee ligament attachments and also include a cyst-like component. Our aim was to determine whether the volume of BML subtypes and synovial tissue volume (STV) was associated with symptoms in symptomatic knee OA. METHOD: Images were acquired in a sub-sample who had taken part in a randomised trial of vitamin D therapy in knee OA (UK-VIDEO). Contrast-enhanced (CE) MRI was performed annually. In those who had ≥1 follow-up and a baseline scan (N = 50), STV and BML volume was assessed. BMLs were categorised by location and by the presence/absence of a cyst-like component. WOMAC was assessed annually. We used fixed-effects panel-regression modelling to examine the association between volume and symptoms. RESULTS: There was no association between knee pain and total subchondral BML volume (b = 0.3 WOMAC units, 95% CI -0.3 to 1.0) or total ligament-based BML volume (b = 1.9, 95% CI -1.6 to 5.3). The volume of subchondral BMLs with a cyst-like component was not associated with pain (b = 0.8, 95% CI -0.5 to 2.1) however, the volume of the cyst-like component itself was associated with pain (b = 51.8, 95% CI 14.2 to 89.3). STV was associated with pain (b = 2.2, 95% CI 0.6 to 3.7). CONCLUSION: The volume of the cyst-like component from subchondral BMLs with a cyst-like component was associated with knee pain. BML location, however, did not influence symptoms. STV was also associated with knee symptoms.

Accuracy of injection and short-term pain relief following intra-articular corticosteroid injection in knee osteoarthritis - an observational study.

BACKGROUND: Intra-articular corticosteroid injections (IACI) are effective treatments for pain in knee osteoarthritis (KOA) but treatment response varies. There is uncertainty as to whether structural factors such as accurate placement of IACI affect outcome. We examined this question in a pragmatic observational study, using ultrasound (US) to verify accuracy of IACI. METHODS: 105 subjects with KOA (mean age 63.1 years, 59% female) routinely referred for IACI underwent assessment of demographic factors, x-ray and US of the knee before aspiration and IACI (based on clinical landmarks) with 40 mg triamcinolone acetonide with lignocaine plus a small amount of atmospheric air by an independent physician. US demonstration of intra-articular mobile air, i.e. a positive air arthrosonogram, was used to determine accurate placement of injection. Both patients and injecting physicians were blind to the US findings. Pain at baseline, three and nine weeks post injection was assessed using the 500 mm WOMAC pain subscale and response defined as ≥ 40% reduction in pain from baseline. Inter-observer reliability of air-arthrosonogram assessment was good: κ 0.79 (three raters). RESULTS: Sixty-three subjects (60.6%) were responders at three weeks and 43 (45.7%) at nine weeks. Seventy-four subjects (70.5%) had a positive arthrosonogram. A positive air arthrosonogram did not associate with a higher rate of response to treatment (p 0.389 at three weeks, p 0.365 at nine weeks). There was no difference in US effusion depth, power Doppler signal or radiographic grade between responders and non-responders to the injection, but female gender associated with response at 3 weeks and previous injection with non-response at 9 weeks. CONCLUSIONS: Accurate intra-articular injection of corticosteroid results did not result in superior outcome in terms of pain compared to inaccurate injection in symptomatic knee OA.

Bone turnover predicts change in volumetric bone density and bone geometry at the radius in men.

Peripheral quantitative computed tomography scans of the distal and midshaft radius were performed in 514 European men aged 40-79 years at baseline and a median of 4.3 years later. Age-related changes in volumetric bone mineral density (vBMD) and bone geometry were greater in men with higher biochemical markers of bone turnover at baseline. INTRODUCTION: This study aimed to determine prospective change in bone density and geometry at the radius in men and examine the influence of bone turnover markers and sex hormones on that change. METHODS: Men aged 40-79 years were recruited from population registers in Manchester (UK) and Leuven (Belgium). At baseline, markers of bone formation (P1NP and osteocalcin) and resorption (ß-cTX and ICTP) were assessed. Total and bioavailable testosterone and oestradiol were also measured. Peripheral quantitative computed tomography (pQCT) was used to scan the radius at distal and midshaft sites at the baseline assessment and a median of 4.3 years later. RESULTS: Five hundred fourteen men, mean (SD) age of 59.6 (10.5) years, contributed to the data. At the midshaft site, there was a significant decrease in mean cortical vBMD (-0.04 %/year), bone mineral content (BMC) (-0.1 %/year) and cortical thickness (-0.4 %/year), while total and medullary area increased (+0.5 and +2.4 %/year respectively). At the distal radius, total vBMD declined (-0.5 %/year) and radial area increased (+0.6 %/year). Greater plasma concentrations of bone resorption and formation markers were associated with greater decline in BMC and cortical area at the midshaft and total vBMD at the distal site. Increased bone resorption was linked with an increase in total and medullary area and decrease in cortical thickness at the midshaft. Sex hormone levels were unrelated to change in pQCT parameters. CONCLUSIONS: Age-related changes in vBMD and bone geometry are greater in men with higher biochemical markers of bone turnover at baseline. Sex hormones have little influence on change in pQCT parameters.

Ethnic differences in bone geometry between White, Black and South Asian men in the UK.

Relatively little is known about the bone health of ethnic groups within the UK and data are largely restricted to women. The aim of this study was to investigate ethnic differences in areal bone mineral density (aBMD), volumetric bone mineral density (vBMD), bone geometry and strength in UK men. White European, Black Afro-Caribbean and South Asian men aged over 40years were recruited from Greater Manchester, UK. aBMD at the spine, hip, femoral neck and whole body were measured by DXA. Bone geometry, strength and vBMD were measured at the radius and tibia using pQCT at the metaphysis (4%) and diaphysis (50% radius; 38% tibia) sites. Adjustments were made for age, weight and height. Black men had higher aBMD at the whole body, total hip and femoral neck compared to White and South Asian men independent of body size adjustments, with no differences between the latter two groups. White men had longer hip axis lengths than both Black and South Asian men. There were fewer differences in vBMD but White men had significantly lower cortical vBMD at the tibial diaphysis than Black and South Asian men (p<0.001). At the tibia and radius diaphysis, Black men had larger bones with thicker cortices and greater bending strength than the other groups. There were fewer differences between White and South Asian men. At the metaphysis, South Asian men had smaller bones (p=0.02) and lower trabecular vBMD at the tibia (p=0.003). At the diaphysis, after size-correction, South Asian men had similar sized bones but thinner cortices than White men; measures of strength were not broadly reduced in the South Asian men. Combining pQCT and DXA measurements has given insight into differences in bone phenotype in men from different ethnic backgrounds. Understanding such differences is important in understanding the aetiology of male osteoporosis.

The effect of vitamin D supplementation on knee osteoarthritis, the VIDEO study: a randomised controlled trial.

OBJECTIVE: Epidemiological data suggest low serum 25-hydroxyvitamin D3 (25-OH-D3) levels are associated with radiological progression of knee osteoarthritis (OA). This study aimed to assess whether vitamin D supplementation can slow the rate of progression. METHOD: A 3-year, double-blind, randomised, placebo-controlled trial of 474 patients aged over 50 with radiographically evident knee OA comparing 800 IU cholecalciferol daily with placebo. Primary outcome was difference in rate of medial joint space narrowing (JSN). Secondary outcomes included lateral JSN, Kellgren & Lawrence grade, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain, function, stiffness and the Get up and Go test. RESULTS: Vitamin D supplementation increased 25-OH-D3 from an average of 20.7 (standard deviation (SD) 8.9) µg/L to 30.4 (SD 7.7) µg/L, compared to 20.7 (SD 8.1) µg/L and 20.3 (SD 8.1) µg/L in the placebo group. There was no significant difference in the rate of JSN over 3 years in the medial compartment of the index knee between the treatment group (average -0.01 mm/year) and placebo group (-0.08 mm/year), average difference 0.08 mm/year (95% confidence interval (CI) [-0.14-0.29], P = 0.49). No significant interaction was found between baseline vitamin D levels and treatment effect. There were no significant differences for any of the secondary outcome measures. CONCLUSION: Vitamin D supplementation did not slow the rate of JSN or lead to reduced pain, stiffness or functional loss over a 3-year period. On the basis of these findings we consider that vitamin D supplementation has no role in the management of knee OA.

Lower bone turnover and relative bone deficits in men with metabolic syndrome: a matter of insulin sensitivity? The European Male Ageing Study.

We examined cross-sectional associations of metabolic syndrome and its components with male bone turnover, density and structure. Greater bone mass in men with metabolic syndrome was related to their greater body mass, whereas hyperglycaemia, hypertriglyceridaemia or impaired insulin sensitivity were associated with lower bone turnover and relative bone mass deficits. INTRODUCTION: Metabolic syndrome (MetS) has been associated with lower bone turnover and relative bone mass or strength deficits (i.e. not proportionate to body mass index, BMI), but the relative contributions of MetS components related to insulin sensitivity or obesity to male bone health remain unclear. METHODS: We determined cross-sectional associations of MetS, its components and insulin sensitivity (by homeostatic model assessment-insulin sensitivity (HOMA-S)) using linear regression models adjusted for age, centre, smoking, alcohol, and BMI. Bone turnover markers and heel broadband ultrasound attenuation (BUA) were measured in 3129 men aged 40-79. Two centres measured total hip, femoral neck, and lumbar spine areal bone mineral density (aBMD, n = 527) and performed radius peripheral quantitative computed tomography (pQCT, n = 595). RESULTS: MetS was present in 975 men (31.2 %). Men with MetS had lower ß C-terminal cross-linked telopeptide (ß-CTX), N-terminal propeptide of type I procollagen (PINP) and osteocalcin (P < 0.0001) and higher total hip, femoral neck, and lumbar spine aBMD (P ≤ 0.03). Among MetS components, only hypertriglyceridaemia and hyperglycaemia were independently associated with PINP and ß-CTX. Hyperglycaemia was negatively associated with BUA, hypertriglyceridaemia with hip aBMD and radius cross-sectional area (CSA) and stress-strain index. HOMA-S was similarly associated with PINP and ß-CTX, BUA, and radius CSA in BMI-adjusted models. CONCLUSIONS: Men with MetS have higher aBMD in association with their greater body mass, while their lower bone turnover and relative deficits in heel BUA and radius CSA are mainly related to correlates of insulin sensitivity. Our findings support the hypothesis that underlying metabolic complications may be involved in the bone's failure to adapt to increasing bodily loads in men with MetS.

The efficacy of intra-articular steroids in hip osteoarthritis: a systematic review.

OBJECTIVE: International guidelines recommend intra-articular steroid injections (IASIs) in the management of hip osteoarthritis (OA), though these recommendations are extrapolated primarily from studies of knee OA. The aim of this systematic review was to assess the efficacy of IASI on pain in hip OA. METHODS: MEDLINE, EMBASE, AMED, CINAHL Plus, Web of Science and the Cochrane Central Register of Controlled Trials were searched to May 2015. Randomised controlled trials (RCTs) assessing the efficacy of hip IASI on pain were included. Pre-specified data was extracted using a standardised form. Quality was assessed using the Jadad score. RESULTS: Five trials met the inclusion criteria. All had a small number of participants (≤101). All studies reported some reduction in pain at 3-4 weeks post-injection compared to control. Based on data from individual trials the treatment effect size was large at 1 week post-injection but declined thereafter. A significant (moderate effect size) reduction in pain was reported in two trials up to 8 weeks following IASI. Pooled results of two trials (n = 90) showed an increased likelihood of meeting the Outcome measures in Rheumatology Clinical Trials (OMERACT)-Osteoarthritis Research Society International (OARSI) response criteria at 8 weeks post-IASI, odds ratio 7.8 (95% confidence interval (CI): 2.7-22.8). The number needed to treat to achieve one OMERACT-OARSI responder at 8 weeks post-injection was 2.4 (95% CI: 1.7-4.2). Hip IASI appear to be generally well tolerated. CONCLUSIONS: Hip IASI may be efficacious in short-term pain reduction in those with hip OA though the quality of the evidence was relatively poor. Further large, methodologically rigorous trials are required to verify whether intra-articular corticosteroids are beneficial and for how long.

Synovial volume vs synovial measurements from dynamic contrast enhanced MRI as measures of response in osteoarthritis.

OBJECTIVE: Synovium is increasingly a target of osteoarthritis (OA) treatment, yet its optimal measurement is unclear. Using dynamic contrast enhanced (DCE) MRI in knee OA patients before and after intraarticular steroid injection, we compared the responsiveness of static synovial volume measures to measures of dynamic changes in synovial enhancement, changes that are strongly related to synovial vascularity. METHODS: Ninety three patients underwent DCE-MRI before and 1-2 weeks after intra-articular injection of 80 mg methylprednisolone. Synovium was segmented and volume, relative enhancement rate (RER), maximum relative enhancement (REmax), late relative enhancement (RElate) and pharmacokinetic parameters (K(trans), ve) were calculated. KOOS (​knee injury and osteoarthritis outcome score) pain score was recorded before and after injection. Standardized change scores were calculated for each parameter. Linear regression and Pearson's correlations were used to investigate the relationship between change in MRI parameters and change in pain. RESULTS: The change in standardized score for the measures of synovial enhancement, RElate and REmax were -0.58 (95% CI -0.79 to -0.37) and -0.62 (95% CI -0.83 to -0.41) respectively, whereas the score for synovial volume was -0.30 (-0.52 to -0.09). Further, change in knee pain correlated more strongly with changes in enhancement (for both REmax and RElate, r = -0.27 (95% CI -0.45 to -0.07)) than with changes in synovial volume -0.15 (-0.35 to 0.05). CONCLUSION: This study suggests DCE-MRI derived measures of synovial enhancement may be more sensitive to the response to treatment and more strongly associated with changes in pain than synovial volume and may be better outcomes for assessment of structural effects of treatment in OA.

Vertebral Scheuermann's disease in Europe: prevalence, geographic variation and radiological correlates in men and women aged 50 and over.

UNLABELLED: In 27 centres across Europe, the prevalence of deforming spinal Scheuermann's disease in age-stratified population-based samples of over 10,000 men and women aged 50+ averaged 8% in each sex, but was highly variable between centres. Low DXA BMD was un-associated with Scheuermann's, helping the differential diagnosis from osteoporosis. INTRODUCTION: This study aims to assess the prevalence of Scheuermann's disease of the spine across Europe in men and women over 50 years of age, to quantitate its association with bone mineral density (BMD) and to assess its role as a confounder for the radiographic diagnosis of osteoporotic fracture. METHODS: In 27 centres participating in the population-based European Vertebral Osteoporosis Study (EVOS), standardised lateral radiographs of the lumbar and of the thoracic spine from T4 to L4 were assessed in all those of adequate quality. The presence of Scheuermann's disease, a confounder for prevalent fracture in later life, was defined by the presence of at least one Schmorl's node or irregular endplate together with kyphosis (sagittal Cobb angle >40° between T4 and T12) or a wedged-shaped vertebral body. Alternatively, the (rare) Edgren-Vaino sign was taken as diagnostic. The 6-point-per-vertebral-body (13 vertebrae) method was used to assess osteoporotic vertebral shape and fracture caseness. DXA BMD of the L2-L4 and femoral neck regions was measured in subsets. We also assessed the presence of Scheuermann's by alternative published algorithms when these used the radiographic signs we assessed. RESULTS: Vertebral radiographic images from 4486 men and 5655 women passed all quality checks. Prevalence of Scheuermann's varied considerably between centres, and based on random effect modelling, the overall European prevalence using our method was 8% with no significant difference between sexes. The highest prevalences were seen in Germany, Sweden, the UK and France and low prevalences were seen in Hungary, Poland and Slovakia. Centre-level prevalences in men and women were highly correlated. Scheuermann's was not associated with BMD of the spine or hip. CONCLUSIONS: Since most of the variation in population impact of Scheuermann's was unaccounted for by the radiological and anthropometric data, the search for new genetic and environmental determinants of this disease is encouraged.

Associations of obesity with socioeconomic and lifestyle factors in middle-aged and elderly men: European Male Aging Study (EMAS).

BACKGROUND: Social and lifestyle influences on age-related changes in body morphology are complex because lifestyle and physiological response to social stress can affect body fat differently. OBJECTIVE: In this study, we examined the associations of socioeconomic status (SES) and lifestyle factors with BMI and waist circumference (WC) in middle-aged and elderly European men. DESIGN AND SETTING: A cross-sectional study of 3319 men aged 40-79 years recruited from eight European centres. OUTCOMES: We estimated relative risk ratios (RRRs) of overweight/obesity associated with unfavourable SES and lifestyles. RESULTS: The prevalence of BMI ≥ 30 kg/m(2) or WC ≥ 102 cm rose linearly with age, except in the eighth decade when high BMI, but not high WC, declined. Among men aged 40-59 years, compared with non-smokers or most active men, centre and BMI-adjusted RRRs for having a WC between 94 and 101.9 cm increased by 1.6-fold in current smokers, 2.7-fold in least active men and maximal at 2.8-fold in least active men who smoked. Similar patterns but greater RRRs were observed for men with WC ≥ 102 cm, notably 8.4-fold greater in least active men who smoked. Compared with men in employment, those who were not in employment had increased risk of having a high WC by 1.4-fold in the 40-65 years group and by 1.3-fold in the 40-75 years group. These relationships were weaker among elderly men. CONCLUSION: Unfavourable SES and lifestyles associate with increased risk of obesity, especially in middle-aged men. The combination of inactivity and smoking was the strongest predictor of high WC, providing a focus for health promotion and prevention at an early age.

Impact of femoral neck and lumbar spine BMD discordances on FRAX probabilities in women: a meta-analysis of international cohorts.

There are occasional marked discordances in BMD T-scores at the lumbar spine (LS) and femoral neck (FN). We investigated whether such discordances could contribute independently to fracture prediction using FRAX. We studied 21,158 women, average age 63 years, from 10 prospective cohorts with baseline FRAX variables as well as FN and LS BMD. Incident fractures were collected by self-report and/or radiographic reports. Extended Poisson regression examined the relationship between differences in LS and FN T-scores (ΔLS-FN) and fracture risk, adjusted for age, time since baseline and other factors including FRAX 10-year probability for major osteoporotic fracture calculated using FN BMD. To examine the effect of an adjustment for ΔLS-FN on reclassification, women were separated into risk categories by their FRAX major fracture probability. High risk was classified using two approaches: being above the National Osteoporosis Guideline Group intervention threshold or, separately, being in the highest third of each cohort. The absolute ΔLS-FN was greater than 2 SD for 2.5% of women and between 1 and 2 SD for 21%. ΔLS-FN was associated with a significant risk of fracture adjusted for baseline FRAX (HR per SD change = 1.09; 95% CI = 1.04-1.15). In reclassification analyses, only 2.3-3.2% of the women moved to a higher or lower risk category when using FRAX with ΔLS-FN compared with FN-derived FRAX alone. Adjustment of estimated fracture risk for a large LS/FN discrepancy (>2SD) impacts to a large extent on only a relatively small number of individuals. More moderate (1-2SD) discordances in FN and LS T-scores have a small impact on FRAX probabilities. This might still improve clinical decision-making, particularly in women with probabilities close to an intervention threshold.

Late-onset hypogonadism and mortality in aging men.

CONTEXT: Late-onset hypogonadism (LOH) has recently been defined as a syndrome in middle-aged and elderly men reporting sexual symptoms in the presence of low T. The natural history of LOH, especially its relationship to mortality, is currently unknown. OBJECTIVE: The aim of this study was to clarify the associations between LOH, low T, and sexual symptoms with mortality in men. DESIGN, SETTING, AND PARTICIPANTS: Prospective data from the European Male Aging Study (EMAS) on 2599 community-dwelling men aged 40-79 years in eight European countries was used for this study. MAIN OUTCOME MEASURE(S): All-cause, cardiovascular, and cancer-related mortality was measured. RESULTS: One hundred forty-seven men died during a median follow-up of 4.3 years. Fifty-five men (2.1%) were identified as having LOH (31 moderate and 24 severe). After adjusting for age, center, body mass index (BMI), current smoking, and poor general health, compared with men without LOH, those with severe LOH had a 5-fold [hazard ratio (HR) 5.5; 95% confidence interval (CI) 2.7, 11.4] higher risk of all-cause mortality. Compared with eugonadal men, the multivariable-adjusted risk of mortality was 2-fold higher in those with T less than 8 nmol/L (irrespective of symptoms; HR 2.3; 95% CI 1.2, 4.2) and 3-fold higher in those with three sexual symptoms (irrespective of serum T; compared with asymptomatic men; HR 3.2; 95% CI 1.8, 5.8). Similar risks were observed for cardiovascular mortality. CONCLUSIONS: Severe LOH is associated with substantially higher risks of all-cause and cardiovascular mortality, to which both the level of T and the presence of sexual symptoms contribute independently. Detecting low T in men presenting with sexual symptoms offers an opportunity to identify a small subgroup of aging men at particularly high risk of dying.
