    Low body mass index (BMI) is a risk factor for fracture, but little is known about the association between high BMI and fracture risk. We evaluated the association between BMI and fracture in the Osteoporotic Fractures in Men Study (MrOS), a cohort of 5995 US men 65 years of age and older. Standardized measures included weight, height, and hip bone mineral density (BMD) by dual-energy X-ray absorptiometry (DXA); medical history; lifestyle; and physical performance. Only 6 men (0.1%) were underweight (<18.5 kg/m(2)); therefore, men in this category were excluded. Also, 27% of men had normal BMI (18.5 to 24.9 kg/m(2)), 52% were overweight (25 to 29.9 kg/m(2)), 18% were obese I (30 to 34.9 kg/m(2)), and 3% were obese II (35 to 39.9 kg/m(2)). Overall, nonspine fracture incidence was 16.1 per 1000 person-years, and hip fracture incidence was 3.1 per 1000 person-years. In age-, race-, and BMD-adjusted models, compared with normal weight, the hazard ratio (HR) for nonspine fracture was 1.04 [95% confidence interval (CI) 0.87-1.25] for overweight, 1.29 (95% CI 1.00-1.67) for obese I, and 1.94 (95% CI 1.25-3.02) for obese II. Associations were weaker and not statistically significant after adjustment for mobility limitations and walking pace (HR = 1.02, 95% CI 0.84-1.23, for overweight; HR = 1.12, 95% CI 0.86-1.46, for obese I, and HR = 1.44, 95% CI 0.90-2.28, for obese II). Obesity is common among older men, and when BMD is held constant, it is associated with an increased risk of fracture. This association is at least partially explained by worse physical function in obese men.

    Previous studies in older men have not evaluated whether loss of BMD or BMC accelerates nonlinearly with age. This study aimed to describe hip bone loss (both in BMC and BMD) in older men and to test whether BMD loss accelerates with age in an exponential manner in a cohort of 4720 community-dwelling men >or=65 yr of age. Men had two to three measures of femoral neck (FN) BMD (by DXA) over an average follow-up of 4.6 yr. Change in BMD during follow-up was estimated from mixed effects regression models; the significance of a quadratic term for age was evaluated. Mean FN BMD loss was 0.013 g/cm(2) (-1.72%) during follow-up. The quadratic term for age was significant, and the model showed that bone loss accelerated with age. Estimated loss of FN BMD over follow-up for men 85 yr of age (0.021 g/cm(2)) was 2.5 times greater than the loss expected for men 65 yr of age (0.008 g/cm(2)); such bone loss in 85-yr-old men may be sufficient to increase the risk of hip fracture by 25% (HR per 0.021 g/cm(2) cross-sectional decrease in FN BMD: 1.25; 95% CI: 1.18-1.31) over 4.6 yr. Men with lower BMD at baseline lost the most BMD over follow-up. Although average bone loss over time is modest in older men, there is considerable variability in rate of loss. Older men and those with lower BMD lose bone more rapidly, offering potential explanation for the increasing risk of fracture with advancing age.

    Objective To study the causes and consequences of radiologically confirmed rib fractures (seldom considered in the context of osteoporosis) in community dwelling older men. Design Prospective cohort study (Osteoporotic Fractures in Men (MrOS) Study). Setting and participants 5995 men aged 65 or over recruited in 2000-2 from six US sites; 99% answered mailed questionnaires about falls and fractures every four months for a mean 6.2 (SD 1.3) year follow-up. Main outcome measures New fractures validated by radiology reports; multivariate Cox proportional hazard ratios were used to evaluate factors independently associated with time to incident rib fracture; associations between baseline rib fracture and incident hip and wrist fracture were also evaluated. Results The incidence of rib fracture was 3.5/1000 person years, and 24% (126/522) of all incident non-spine fractures were rib fractures. Nearly half of new rib fractures (48%; n=61) followed falling from standing height or lower. Independent risk factors for an incident rib fracture were age 80 or above, low bone density, difficulty with instrumental activities of daily living, and a baseline history of rib/chest fracture. Men with a history of rib/chest fracture had at least a twofold increased risk of an incident rib fracture (adjusted hazard ratio 2.71, 95% confidence interval 1.86 to 3.95), hip fracture (2.05, 1.33 to 3.15), and wrist fracture (2.06, 1.14 to 3.70). Only 14/82 of men reported being treated with bone specific drugs after their incident rib fracture. Conclusions Rib fracture, the most common incident clinical fracture in men, was associated with classic risk markers for osteoporosis, including old age, low hip bone mineral density, and history of fracture. A history of rib fracture predicted a more than twofold increased risk of future fracture of the rib, hip, or wrist, independent of bone density and other covariates. Rib fractures should be considered to be osteoporotic fractures in the

    Purpose To evaluate the utility of recommended laboratory testing to identify secondary causes in older men with osteoporosis, we examined prevalence of laboratory abnormalities in older men with and without osteoporosis. Methods 1572 men aged ≥65 years in the Osteoporotic Fractures in Men study completed bone mineral density (BMD) testing and a battery of laboratory measures, including serum calcium, phosphorus, alkaline phosphatase, parathyroid hormone (PTH), thyroid-stimulating hormone (TSH), 25-OH vitamin D, total testosterone, spot urine calcium/creatinine ratio, spot urine albumin-creatinine ratio, creatinine-derived estimate glomerular filtration rate, 24-hour urine calcium, and 24-hour urine free cortisol. Using cross-sectional analyses, we calculated prevalence ratios (PR) and 95% confidence intervals (CI) for the association of any and specific laboratory abnormalities with osteoporosis, and the number of men with osteoporosis needed to test to identify one additional laboratory abnormality compared to testing men without osteoporosis. Results Approximately 60% of men had ≥1 laboratory abnormality in both men with and without osteoporosis. Among individual tests, only vitamin D insufficiency (PR, 1.13; 95% CI, 1.05–1.22) and high alkaline phosphatase (PR, 3.05; 95% CI, 1.52–6.11) were more likely in men with osteoporosis. Hypercortisolism and hyperthyroidism were uncommon and not significantly more frequent in men with osteoporosis. No osteoporotic men had hypercalciuria. Conclusions Though most of these older men had ≥1 laboratory abnormality, few routinely recommended individual tests were more common in men with osteoporosis than in those without osteoporosis. Possibly excepting vitamin D and alkaline phosphatase, benefit of routine laboratory testing to identify possible secondary causes in older osteoporotic men appears low. Results may not be generalizable to younger men or to older men in whom history and exam findings raise clinical

    We evaluated the performance of the Fracture Risk Calculator (FRC) in 5893 men who participated in the baseline visit (March 2000-April 2002) of the Osteoporotic Fractures in Men Study. FRC estimates for 10-yr hip and major osteoporotic (hip, clinical spine, forearm, and shoulder) fractures were calculated and compared with observed 10-yr fracture probabilities. Possible enhancement of the tool's performance when bone mineral density (BMD) was included was evaluated by comparing areas under receiver operating characteristic curves and by Net Reclassification Improvement (NRI). A total of 5893 men were followed-up for an average of 8.4 yr. For most quintiles of predicted fracture risk, the ratios of observed to predicted probabilities were close to unity. Area under the curves improved when BMD was included (p<0.001; 0.79 vs 0.71 for hip fracture and 0.70 vs 0.66 for major osteoporotic fracture, respectively). Using National Osteoporosis Foundation clinical treatment thresholds, BMD inclusion increased NRI significantly, 8.5% (p<0.01) for hip and 4.0% (p=0.01) for major osteoporotic fracture. We conclude that the FRC calibrates well with hip and major osteoporotic fractures observed among older men. Further, addition of BMD to the fracture risk calculation improves the tool's performance.

    Dietary protein is a potentially modifiable risk factor for fracture. Our objectives were to assess the association of protein intake with incident fracture among older men and whether these associations varied by protein source or by skeletal site. We studied a longitudinal cohort of 5875 men (mean age 73.6 ± 5.9 years) in the Osteoporotic Fractures in Men (MrOS) study. At baseline, protein intake was assessed as percent of total energy intake (TEI) with mean intake from all sources = 16.1%TEI. Incident clinical fractures were confirmed by physician review of medical records. There were 612 major osteoporotic fractures, 806 low-trauma fractures, 270 hip fractures, 193 spine fractures, and 919 non-hip non-spine fractures during 15 years of follow-up. We used Cox proportional hazards models with age, race, height, clinical site, TEI, physical activity, marital status, osteoporosis, gastrointestinal surgery, smoking, oral corticosteroids use, alcohol consumption, and calcium and vitamin D supplements as covariates to compute hazard ratios (HRs) with 95% confidence intervals (CIs), all expressed per unit (SD = 2.9%TEI) increase. Higher protein intake was associated with a decreased risk of major osteoporotic fracture (HR = 0.92; 95% CI, 0.84 to 1.00) with a similar association found for low-trauma fracture. The association between protein and fracture varied by protein source; eg, increased dairy protein and non-dairy animal protein were associated with a decreased risk of hip fracture (HR = 0.80 [95% CI, 0.65 to 0.98] and HR = 0.84 [95% CI, 0.72 to 0.97], respectively), whereas plant-source protein was not (HR = 0.99 [95% CI, 0.78 to 1.24]). The association between protein and fracture varied by fracture site; total protein was associated with a decreased risk of hip fracture (HR = 0.84 [95% CI, 0.73 to 0.95]), but not clinical spine fracture (HR = 1.06 [95% CI, 0.92 to 1.22]). In conclusion, those with high protein intake

    Trabecular bone score (TBS) has been shown to predict major osteoporotic (clinical vertebral, hip, humerus, and wrist) and hip fractures in postmenopausal women and older men, but the association of TBS with these incident fractures in men independent of prevalent radiographic vertebral fracture is unknown. TBS was estimated on anteroposterior (AP) spine dual-energy X-ray absorptiometry (DXA) scans obtained at the baseline visit for 5979 men aged ≥65 years enrolled in the Osteoporotic Fractures in Men (MrOS) Study and its association with incident major osteoporotic and hip fractures estimated with proportional hazards models. Model discrimination was tested with Harrell's C-statistic and with a categorical net reclassification improvement index, using 10-year risk cutpoints of 20% for major osteoporotic and 3% for hip fractures. For each standard deviation decrease in TBS, there were hazard ratios of 1.27 (95% confidence interval [CI] 1.17 to 1.39) for major osteoporotic fracture, and 1.20 (95% CI 1.05 to 1.39) for hip fracture, adjusted for FRAX with bone mineral density (BMD) 10-year fracture risks and prevalent radiographic vertebral fracture. In the same model, those with prevalent radiographic vertebral fracture compared with those without prevalent radiographic vertebral fracture had hazard ratios of 1.92 (95% CI 1.49 to 2.48) for major osteoporotic fracture and 1.86 (95% CI 1.26 to 2.74) for hip fracture. There were improvements of 3.3%, 5.2%, and 6.2%, respectively, of classification of major osteoporotic fracture cases when TBS, prevalent radiographic vertebral fracture status, or both were added to FRAX with BMD and age, with minimal loss of correct classification of non-cases. Neither TBS nor prevalent radiographic vertebral fracture improved discrimination of hip fracture cases or non-cases. In conclusion, TBS and prevalent radiographic vertebral fracture are associated with incident major osteoporotic fractures in older men independent of each other

    Almost 30% of hip fractures occur in men; the mortality, morbidity, and loss of independence after hip fractures are greater in men than in women. To comprehensively evaluate risk factors for hip fracture in older men, we performed a prospective study of 5994 men, primarily white, age 65+ years recruited at six US clinical centers. During a mean of 8.6 years of 97% complete follow-up, 178 men experienced incident hip fractures. Information on risk factors including femoral neck bone mineral density (FNBMD) was obtained at the baseline visit. Cox proportional hazards models were used to calculate the hazard ratio (HR) with 95% confidence intervals; Fine and Gray models adjusted for competing mortality risk. Older age (≥75 years), low FNBMD, currently smoking, greater height and height loss since age 25 years, history of fracture, use of tricyclic antidepressants, history of myocardial infarction or angina, hyperthyroidism or Parkinson's disease, lower protein intake, and lower executive function were all associated with an increased hip fracture risk. Further adjustment for competing mortality attenuated HR for smoking, hyperthyroidism, and Parkinson's disease. The incidence rate of hip fracture per 1000 person-years (PY) was greatest in men with FNBMD T-scores hip fracture at rates of 14.52 versus 0.88 per 1000 PY in men age hip fracture. Many of these assessments can easily be incorporated into routine clinical practice and may lead to improved risk stratification. © 2016 American Society for Bone and Mineral Research. © 2016 American Society for Bone and Mineral Research.

    Normal mineral metabolism is critical for skeletal integrity, and recently serum fibroblast growth factor 23 (FGF23) levels were found to be directly related to overall fracture risk in elderly Swedish men. To confirm this association, we performed a prospective case-cohort study to understand the relation of FGF23 and fracture risk in older white men enrolled in the Osteoporotic Fractures in Men (MrOS) study. In the cohort of 5994 men attending the baseline MrOS examination, we evaluated a subgroup of 387 men with incident nonvertebral fracture including 73 hip fractures and a sample of 1385 men randomly selected from the cohort with baseline mineral and calcium hormone measurements. FGF23 was measured in baseline serum samples by ELISA (Millipore, Billerica, MA, USA). Modified Cox proportional hazards models that account for case-cohort study design were used to estimate the relative hazards (RH) of fracture in men across quartiles of FGF23. Subjects were also stratified by renal function, and RH per strata was estimated in men with the highest quartile of FGF23 compared with quartiles 3, 2, and 1. Overall, there was no difference in risk of nonspine or hip fracture by baseline FGF23. However, associations differed by strata of eGFRCrCy . Among men with eGFRCrCys 60 mL/min/1.73 m2 (304/1370 fractures) the RH was 0.91 (95% CI 0.66-1.25) after adjustment for age, clinic site, body mass index, race, total hip bone mineral density, vitamin D, parathyroid hormone, alcohol use, physical activity, fracture history, and serum phosphorus. Serum FGF23 levels are not associated with incident fractures in elderly men overall. However, higher levels of serum FGF23 are associated with fracture risk in those with poor renal function.

    Low 25-hydroxyvitamin D (VitD), low sex hormones (SH), and high sex hormone binding globulin (SHBG) levels are common in older men. We tested the hypothesis that combinations of low VitD, low SH, and high SHBG would have a synergistic effect on bone mineral density (BMD), bone loss, and fracture risk in older men. Participants were a random subsample of 1468 men (mean age 74 years) from the Osteoporotic Fractures in Men Study (MrOS) plus 278 MrOS men with incident nonspine fractures studied in a case-cohort design. "Abnormal" was defined as lowest quartile for VitD (59 nM). Overall, 10% had isolated VitD deficiency; 40% had only low SH or high SHBG; 15% had both SH/SHBG and VitD abnormality; and 35% had no abnormality. Compared to men with all normal levels, those with both SH/SHBG and VitD abnormality tended to be older, more obese, and to report less physical activity. Isolated VitD deficiency, and low BioT with or without low VitD, was not significantly related to skeletal measures. The combination of VitD deficiency with low BioE and/or high SHBG was associated with significantly lower baseline BMD and higher annualized rates of hip bone loss than SH abnormalities alone or no abnormality. Compared to men with all normal levels, the multivariate-adjusted hazard ratio (95% confidence interval [CI]) for incident nonspine fracture during 4.6-year median follow-up was 1.2 (0.8-1.8) for low VitD alone; 1.3 (0.9-1.9) for low BioE and/or high SHBG alone; and 1.6 (1.1-2.5) for low BioE/high SHBG plus low VitD. In summary, adverse skeletal effects of low sex steroid levels were more pronounced in older men with low VitD levels. The presence of low VitD in the presence of low BioE/high SHBG may contribute substantially to poor skeletal health.

    The association between vitamin D status and diabetes risk is inconsistent among observational studies, and most of the available studies have been with women. In the present study we investigated the association between serum 25-hydroxyvitamin D (25(OH)D) levels and incident type 2 diabetes (T2D) in older men (≥65years old) who participated in the multisite Osteoporotic Fractures in Men (MrOS) study enrolled from March 2000 to April 2002. Baseline 25(OH)D levels were available in 1939 subjects without prevalent T2D. Clinical information, body mass index (BMI) and other factors related to T2D were assessed at the baseline visit. Incident diabetes, defined by self-report and medication use, was determined over an average follow-up of 6.4years. At baseline, participants were, on average, 73.3 (±5.7) years old, had a mean BMI in the overweight range (27.2kg/m(2)±3.6) and had total serum 25(OH)D of 26.1ng/ml (±8.3). Incident diabetes was diagnosed in 139 subjects. Cox regression analysis showed a trend toward a protective effect of higher 25(OH)D levels with a lower risk of T2D (HR 0.87, 95% CI: 0.73-1.04 per 1 SD increase of 25(OH)D). After adjusted for BMI and other potential confounders, the relationship between 25(OH)D levels and incident diabetes was further attenuated (HR 1.03, 95% CI 0.85-1.25). No significant difference in the incidence of diabetes emerged after analyzing study subjects according to baseline 25(OH)D quartiles. In conclusion, 25(OH)D levels were not associated with incident T2D in older men.

    The lifespan of men is increasing and this is associated with an increased prevalence of osteoporosis in men. Osteoporosis increases the risk of bone fracture. Fractures are associated with increased disability and mortality, and public health problems. We review here the study of osteoporosis in men as obtained from a longitudinal cohort of community-based older men, the Osteoporotic Fractures in Men Study (MrOS).

    A higher serum phosphorus level is associated with cardiovascular disease (CVD) events among community-living populations. Mechanisms are unknown. The ankle-brachial index (ABI) provides information on both atherosclerosis and arterial stiffness. In this cross-sectional study (2000-2002), the authors evaluated the association of serum phosphorus levels with low ( or =1.40 or incompressible) ABI as compared with intermediate ABI in 5,330 older US men, among whom the mean serum phosphorus level was 3.2 mg/dL (standard deviation, 0.4), 6% had a low ABI, and 5% had a high ABI. Each 1-mg/dL increase in serum phosphorus level was associated with a 1.6-fold greater prevalence of low ABI (95% confidence interval (CI): 1.2, 2.1; P < 0.001) and a 1.4-fold greater prevalence of high ABI (95% CI: 1.0, 1.9; P = 0.03) in models adjusted for demographic factors, traditional CVD risk factors, and kidney function. However, the association of phosphorus with high ABI differed by chronic kidney disease (CKD) status (in persons with CKD, prevalence ratio = 2.96, 95% CI: 1.61, 5.45; in persons without CKD, prevalence ratio = 1.14, 95% CI: 0.81, 1.61; interaction P = 0.04). In conclusion, among community-living older men, higher phosphorus levels are associated with low ABI and are also associated with high ABI in persons with CKD. These associations may explain the link between serum phosphorus levels and CVD events.

    This prospective case-cohort study aimed to map the distribution of bone density in the proximal femur and examine its association with hip fracture. We analyzed baseline quantitative computed tomography (QCT) scans in 250 men aged 65 years or older, which comprised a randomly-selected subcohort of 210 men and 40 cases of first hip fracture during a mean follow-up period of 5.5 years. We quantified cortical, trabecular, and integral volumetric bone mineral density (vBMD), and cortical thickness (CtTh) in four quadrants of cross-sections along the length of the femoral neck (FN), intertrochanter (IT), and trochanter (TR). In most quadrants, vBMDs and CtTh were significantly (p hip fracture, we merged the two quadrants in the medial and lateral aspects of the FN, IT, and TR. At most sites, QCT measurements were associated significantly (p hip fracture, the hazard ratio (HR) adjusted for age, body mass index (BMI), and clinical site for a 1-SD decrease ranged between 2.28 (95% confidence interval [CI], 1.44-3.63) to 6.91 (95% CI, 3.11-15.53). After additional adjustment for total hip (TH) areal BMD (aBMD), trabecular vBMDs at the FN, TR, and TH were still associated with hip fracture significantly (p fracture significantly (p > 0.05) better than TH aBMD. With an area under the receiver operating characteristic curve (AUC) of 0.901 (95% CI, 0.852-0.950), the regression model combining TH aBMD, age, and trabecular vBMD predicted hip fracture significantly (p hip fracture risk and highlight trabecular vBMD at the FN and TR as an independent risk factor.

    Context: Periodontitis is an inflammatory disease of tooth-supporting tissue leading to bone destruction and tooth loss. Periodontitis affects almost 50% of adults greater than 30 years of age. Objective: This study evaluated the association between biomarkers linked to bone formation and resorption with the occurrence and progression of periodontal disease in older men (≥65 y). Design: The Osteoporotic Fractures in Men (MrOS) study is a prospective, observational study among men 65 years of age and older. Setting: This ancillary study, Oral and Skeletal Bone Loss in Older Men, was conducted at two of the six MrOS study sites (Birmingham, AL and Portland, OR). Patients: Patients underwent medical and dental evaluation. Diagnoses of periodontitis were based on clinical attachment loss, pocket depth, calculus, plaque, and bleeding on a random half-mouth. Bone metabolism biomarkers included serum levels of calcium, phosphate (Pi), alkaline phosphatase, albumin, carboxy-terminal collagen crosslinks (CTX), N-terminal propeptides of type I procollagen, isoform 5b of tartrate-resistant acid phosphatase, and urine alpha- carboxy-terminal collagen crosslinks (alpha-CTX) and beta-CTX and serum levels of calciotropic hormones vitamin D (25(OH)D) and PTH. Main Outcome Measures: The aim of this study is to correlate bone metabolism biomarkers with prevalence and progression of periodontal disease in older men. Results: Patients with more severe periodontitis had significantly higher levels of PTH (P trend = .0004), whereas 25(OH)D was lower (P trend = .001). In a subset of men reevaluated at a second dental visit, improvement of periodontitis was associated with lower alpha-CTX, beta-CTX, and CTX levels at baseline after adjusting for age, site, and body mass index. Conclusion: This study suggests that a distinct set of biomarkers of bone metabolism are associated with more severe periodontal disease (PTH, 25(OH)D) and periodontal progression (alpha-CTX, beta-CTX, and CTX

    This study examined stereotypes of older lesbians and gay men. Key findings are that older lesbians and gay men were perceived as similar to older heterosexual women and men with regard to aging stereotypes, such as being judicious. At the same time, sexual minorities were targets of unique stereotypes. Consistent with the implicit inversion…

    No studies have compared how well different prediction models discriminate older men who have a radiographic prevalent vertebral fracture (PVFx) from those who do not. We used area under receiver operating characteristic curves and a net reclassification index to compare how well regression-derived prediction models and nonregression prediction tools identify PVFx among men age ≥65 yr with femoral neck T-score of -1.0 or less enrolled in the Osteoporotic Fractures in Men Study. The area under receiver operating characteristic for a model with age, bone mineral density, and historical height loss (HHL) was 0.682 compared with 0.692 for a complex model with age, bone mineral density, HHL, prior non-spine fracture, body mass index, back pain, grip strength, smoking, and glucocorticoid use (p values for difference in 5 bootstrapped samples 0.14-0.92). This complex model, using a cutpoint prevalence of 5%, correctly reclassified only a net 5.7% (p = 0.13) of men as having or not having a PVFx compared with a simple criteria list (age ≥ 80 yr, HHL >4 cm, or glucocorticoid use). In conclusion, simple criteria identify older men with PVFx and regression-based models. Future research to identify additional risk factors that more accurately identify older men with PVFx is needed.

    Full Text Available Although osteoporosis mainly affects women, it could also be seen in men. The aims of the this study were to evaluate the risk factors for osteoporosis in men and to determine their relationships with each other. 49 men with osteoporosis were enrolled in the study. The participants completed a questionnaire covering education, work, alcohol intake, smoking, milk consumption, physical activity and oral glucocorticoid therapy. Additionally, Beck Depression and Visual Analogue Scales were used to assess depression and back pain level. Bone mineral density measurements of the lumbar spine (L2-L4, neck of femur and Ward’s triangle zone were performed by means of dual energy x-ray absorptiometer (DEXA. Dorsal, lumbar x-ray images were taken. According to WHO criteria, patients having Tscores of BMD ≥ -2.5 SD were included. In all patients, positive correlation between the length of education and exercise (r=0.305, p=0.03 and a negative correlation with milk consumption (r= -0.428, p=0.002 were found. Beck Deepression Scale scores were lower in working patients (r=0.457, p=0.001. There was positive corelation between Beck Depression and Visual Analogue Scales values (r=0.376, p=0.01. In men, life style and habits of the individual could be risk factors for osteoporosis and these issues should be taken into consideration before the planning of the treatment.

    Uric acid (UA) is produced from purines by the enzyme xanthine oxidase, and elevated levels may cause arthritis and kidney stones. Conversely, UA also appears to function as an antioxidant and may protect against the oxidative stress associated with aging and disease. We performed a prospective fracture case-cohort study to understand the relation of UA and fracture risk in older men enrolled in the Osteoporotic Fractures in Men (MrOS) study. In the cohort of 5994 men aged 65 years and older attending the baseline MrOS examination, we evaluated a subgroup 1680 men in a case-cohort study design. The analytic group included 387 men with incident nonspine fractures (73 hip) and a random sample of 1383. Serum UA was measured in baseline serum samples. Modified proportional hazards models that account for case-cohort study design were used to estimate the relative hazards (RH) of hip and nonspine fracture in men for serum UA. Models were adjusted for age, race, clinic site, body mass index, vitamin D, parathyroid hormone, walking speed, Physical Activity Scale for the Elderly (PASE) score, frailty, and total. Subjects with incident nonspine fractures were older, had lower total hip bone mineral density (BMD), and higher serum phosphorus. There was an 18% decreased risk of nonspine fractures (95% confidence interval [CI] 0.71-0.93; p = 0.003) per 1 SD increase of baseline serum and 34% decreased risk of nonspine fractures in quartile 4 of UA versus quartiles 1, 2, and 3 (95% CI 0.49-0.89; p = 0.028) compared with nonfracture cases after multivariate adjustment. Hip fractures were not significantly associated with UA. Total hip BMD was significantly higher in the group of men with high UA levels compared with lower UA levels and increased linearly across quartiles of UA after multivariate adjustment (p for trend = 0.002). In summary, higher serum UA levels were associated with a reduction in risk of incident nonspine fractures but not hip fractures and higher hip BMD.

    Full Text Available Abstract Background Osteoporosis is a serious health problem that worsens the quality of life and the survival rate of individuals with this disease on account the osteoporotic fractures. Studies have long focused on women, and its presence in men has been underestimated. While many studies conducted in different countries mainly assess health-related quality of life and identify fracture risks factors in women, few data are available on a Spanish male population. Methods/Design Observational study. Study population Men ≥ 40 years of age with/without diagnosed osteoporosis and with/without osteoporotic fracture included by their family doctor. Measurements The relationship between customary clinical risk factors for osteoporotic fracture and health-related quality of life in a Spanish male population. A telephone questionnaire on health-related quality of life is made. Statistical analysis The association between qualitative variables will be assessed by the Chi-square test. The distribution of quantitative variables by Student's t-test. If the conditions for using this test are not met, the non-parametric Mann-Whitney's U test will be used. The validation of the results obtained by the FRAX™ tool will be performed by way of the Hosmer-Lemeshow test and by calculating the area under the Receiver Operating Characteristic (ROC curve (AUC. All tests will be performed with a confidence intervals set at 95%. Discussion The applicability and usefulness of Health-related quality of life (HRQOL studies are well documented in many countries. These studies allow implementing cost-effective measures in cases of a given disease and reducing the costly consequences derived therefrom. This study attempts to provide objective data on how quality of life is affected by the clinical aspects involved in osteoporosis in a Spanish male population and can be useful as well in cost utility analyses conducted by health authorities. The sample selected is not based

    Adipocytes and osteoblasts share a common progenitor, and there is, therefore, potential for both autocrine and endocrine effects of adiponectin on skeletal metabolism. The aim of the present study was to determine whether high serum adiponectin was associated with an increased risk of fracture in elderly men. We studied the relationship between serum adiponectin and the risk of fracture in 999 elderly men drawn from the general population and recruited to the Osteoporotic Fractures in Men (MrOS) study in Gothenburg, Sweden. Baseline data included general health questionnaires, lifestyle questionnaires, body mass index (BMI), bone mineral density (BMD), serum adiponectin, osteocalcin, and leptin. Men were followed for up to 7.4 years (average, 5.2 years). Poisson regression was used to investigate the relationship between serum adiponectin, other risk variables and the time-to-event hazard function of fracture. Median levels of serum adiponectin at baseline were 10.4 µg/mL (interquartile range, 7.7-14.3). During follow-up, 150 men sustained one or more fractures. The risk of fracture increased in parallel with increasing serum adiponectin (hazard ratio [HR]/SD, 1.46; 95% confidence interval [CI], 1.23-1.72) and persisted after multivariate-adjusted analysis (HR/SD, 1.30; 95% CI, 1.09-1.55). Serum adiponectin shows graded stepwise association with a significant excess risk of fracture in elderly men that was independent of several other risk factors for fracture. Its measurement holds promise as a risk factor for fracture in men.

    Full Text Available Stephen E Borst, Thomas MulliganGeriatrics Research, Education, and Clinical Center, North Florida/South Georgia Veterans Health System, Gainesville, FL, USAAbstract: Despite intensive research on testosterone therapy for older men, important questions remain unanswered. The evidence clearly indicates that many older men display a partial androgen deficiency. In older men, low circulating testosterone is correlated with low muscle strength, with high adiposity, with insulin resistance and with poor cognitive performance. Testosterone replacement in older men has produced benefits, but not consistently so. The inconsistency may arise from differences in the dose and duration of testosterone treatment, as well as selection of the target population. Generally, studies reporting anabolic responses to testosterone have employed higher doses of testosterone for longer treatment periods and have targeted older men whose baseline circulating bioavailable testosterone levels were low. Most studies of testosterone replacement have reported anabolic that are modest compared to what can be achieved with resistance exercise training. However, several strategies currently under evaluation have the potential to produce greater anabolic effects and to do so in a safe manner. At this time, testosterone therapy can not be recommended for the general population of older men. Older men who are hypogonadal are at greater risk for the catabolic effects associated with a number of acute and chronic medical conditions. Future research is likely to reveal benefits of testosterone therapy for some of these special populations. Testosterone therapy produces a number of adverse effects, including worsening of sleep apnea, gynecomastia, polycythemia and elevation of PSA. Efficacy and adverse effects should be assessed frequently throughout the course of therapy.Keywords: aging, testosterone, hypogonadism, physical function

    Hyponatremia may be a risk factor for fracture. To determine the relationship between hyponatremia and fracture we conducted cross-sectional and longitudinal analyses using data from the Osteoporotic Fractures in Men Study (MrOS). The MrOS study enrolled 5122 community dwelling men aged ≥ 65 years from six centers across the United States. We excluded men taking bisphosphonates, those with unknown medication history, those without serum sodium measures, or those with out of range assays for serum sodium. Serum sodium was measured at study entry. Subjects were followed for fractures (nonspine (including hip), hip, and incident and prevalent morphometric) for up to 9 years. We used cox proportional hazards models to analyze the association between serum sodium levels (<135mmol/L versus ≥135mmol/L) and risk of nonspine and hip fractures, with results presented as hazard ratios (HR) and 95% confidence intervals (CI). We examined the association between morphometric vertebral fractures and serum sodium using logistic regression models, presented as odds ratios (OR) and 95% CI. Hyponatremia was observed in 64 men (1.2% of the cohort). After adjusting for age, BMI, study center, and other covariates, we found that, compared to men with serum sodium ≥ 135mmol/L, those with serum sodium <135mmol/L, had an increased risk hip fracture (HR=3.04; 95% CI: 1.37 to 6.75), prevalent (OR=2.46; 95% CI: 1.22 to 4.95) and incident (OR=3.53; 95% CI: 1.35 to 9.19) morphometric spine fractures but not nonspine fractures (OR=1.44; 95% CI: 0.85 to 2.44). Adjusting for bone mineral density did not change our findings. Our data demonstrate that hyponatremia is associated with up to a doubling in the risk of hip and morphometric spine fractures, independent of BMD. Further studies, to determine how hyponatremia causes fractures and if correction of hyponatremia decreases fractures, are needed. PMID:25294595

    Cytokines play major roles in regulating bone remodeling, but their relationship to incident fractures in older men is uncertain. We tested the hypothesis that men with higher concentrations of pro-inflammatory markers have a higher risk of fracture. We used a case-cohort design and measured inflammatory markers in a random sample of 961 men and in men with incident fractures including 120 clinical vertebral, 117 hip, and 577 non-spine fractures; average follow-up 6.13 years (7.88 years for vertebral fractures). We measured interleukin (IL)-6, C-reactive protein (CRP), tumor necrosis factor alpha (TNFα), soluble receptors (SR) of IL-6 (IL-6SR) and TNF (TNFαSR1 and TNFαSR2), and IL-10. The risk of non-spine, hip, and clinical vertebral fracture was compared across quartiles (Q) of inflammatory markers using Cox proportional hazard models with tests for linear trend. In multivariable-adjusted models, men with the highest (Q4) TNFa cytokine concentrations and their receptors had a 2.0-4.2-fold higher risk of hip and clinical vertebral fracture than men with the lowest (Q1). Results were similar for all non-spine fractures, but associations were smaller. There was no association between CRP and IL-6SR and fracture. Men in the highest Q of IL-10 had a 49% lower risk of vertebral fracture compared with men in Q1. Among men with ≥3 inflammatory markers in the highest Q, the hazard ratio (HR) for hip fractures was 2.03 (95% confidence interval [CI] 1.11-3.71) and for vertebral fracture 3.06 (1.66-5.63). The HRs for hip fracture were attenuated by 27%, 27%, and 15%, respectively, after adjusting for appendicular lean mass (ALM), disability, and bone density, suggesting mediating roles. ALM also attenuated the HR for vertebral fractures by 10%. There was no association between inflammation and rate of hip BMD loss. We conclude that inflammation may play an important role in the etiology of fractures in older men. © 2016 American Society for Bone and Mineral Research.

    The adrenal-derived hormones dehydroepiandrosterone (DHEA) and its sulfate (DHEAS) are the most abundant circulating hormones and their levels decline substantially with age. DHEAS is considered an inactive precursor, which is converted into androgens and estrogens via local metabolism in peripheral target tissues. The predictive value of serum DHEAS for fracture risk is unknown. The aim of this study was, therefore, to assess the associations between baseline DHEAS levels and incident fractures in a large cohort of older men. Serum DHEAS levels were analyzed with mass spectrometry in the population-based Osteoporotic Fractures in Men study in Sweden (n = 2568, aged 69 to 81 years). Incident X-ray validated fractures (all, n = 594; non-vertebral major osteoporotic, n = 255; hip, n = 175; clinical vertebral, n = 206) were ascertained during a median follow-up of 10.6 years. DHEAS levels were inversely associated with the risk of any fracture (hazard ratio [HR] per SD decrease = 1.14, 95% confidence interval [CI] 1.05-1.24), non-vertebral major osteoporotic fractures (HR = 1.31, 95% CI 1.16-1.48), and hip fractures (HR = 1.18, 95% CI 1.02-1.37) but not clinical vertebral fractures (HR = 1.09, 95% CI 0.95-1.26) in Cox regression models adjusted for age, body mass index (BMI) and prevalent fractures. Further adjustment for traditional risk factors for fracture, bone mineral density (BMD), and/or physical performance variables as well as serum sex steroid levels only slightly attenuated the associations between serum DHEAS and fracture risk. Similarly, the point estimates were only marginally reduced after adjustment for FRAX estimates with BMD. The inverse association between serum DHEAS and all fractures or major osteoporotic fractures was nonlinear, with a substantial increase in fracture risk (all fractures 22%, major osteoporotic fractures 33%) for those participants with serum DHEAS levels below the median (0.60 μg/mL).

    Full Text Available Abstract Background Osteoporosis and osteoporotic fracture in men are significant public health problems in an aging society. However, information on male osteoporosis remains impressively lacking, especially for Asians. We designed the Fujiwara-kyo Osteoporosis Risk in Men (FORMEN study as an ancillary study of a cohort study, the Fujiwara-kyo study, to determine risk factors for osteoporotic fractures in Japanese men. Methods/Design Design: A community-based single-centre prospective cohort study with at least a 5-year follow-up Subjects: All the male participants of the Fujiwara-kyo study who were living in the four cities studied, aged 65 years and older, and able to walk without aid from others. Primary outcome: Incidence of osteoporotic fractures including vertebral and clinical non-vertebral fractures. Additional outcomes: Change in bone mineral density (BMD, change in hip geometry, onset of receiving benefits from Long-term Care Insurance (LCI, health-related quality of life, and mortality. Baseline measurements: BMD at the lumbar spine (LS and hip (TH, hip geometry, vertebral deformity assessment, bone turnover markers, physical and cognitive performance, various medical and lifestyle factors, and geriatric psychosocial measures confirmed by interviews based on self-administrated questionnaires. Outcome surveillance: Annual mail surveys and a follow-up survey at the fifth year comprising similar items to the baseline study will be used to determine the outcomes. Receipt of benefits from LCI and mortality will be obtained from the city governments. Current status: The baseline study was conducted for 2174 eligible men, and 2012 completed the study and were eligible for follow-up. Prevalence rates of osteoporosis (BMD 2.5 SD or more below the young adult mean (YAM and low BMD (BMD 1 SD or more below YAM in at least one of LS and TH were calculated to be 4.4% and 41.8%, respectively.

    Hip fractures are the most devastating consequence of osteoporosis and impact 1 in 6 white women leading to a two- to threefold increased mortality risk in the first year. Despite evidence of inflammatory markers in the pathogenesis of osteoporosis, few studies have examined their effect on hip fracture. To determine if high levels of inflammation increase hip fracture risk and to explore mediation pathways, a case-cohort design nested in a cohort of 4709 white women from the Study of Osteoporotic Fractures was used. A random sample of 1171 women was selected as the subcohort (mean age 80.1 ± 4.2 years) plus the first 300 women with incident hip fracture. Inflammatory markers interleukin-6 (IL-6) and soluble receptors (SR) for IL-6 (IL-6 SR) and tumor necrosis factor (TNF SR1 and TNF SR2) were measured, and participants were followed for a median (interquartile range) of 6.3 (3.7, 6.9) years. In multivariable models, the hazard ratio (HR) of hip fracture for women in the highest inflammatory marker level (quartile 4) was 1.64 (95% confidence interval [CI], 1.09-2.48, p trend = 0.03) for IL-6 and 2.05 (95% CI, 1.35-3.12, p trend hip fracture was 1.51 (95% CI, 1.07-2.14) and 1.42 (95% CI, 0.87-2.31) compared with women with zero to one marker(s) in the highest quartile (p trend = 0.03). After individually adjusting for seven potential mediators, cystatin-C (a biomarker of renal function) and bone mineral density (BMD) attenuated HRs among women with the highest inflammatory burden by 64% and 50%, respectively, suggesting a potential mediating role. Older white women with high inflammatory burden are at increased risk of hip fracture in part due to poor renal function and low BMD. © 2014 American Society for Bone and Mineral Research.

    Many fractures occur in individuals without osteoporosis defined by areal bone mineral density (aBMD). Inclusion of other aspects of skeletal strength may be useful in identifying at-risk subjects. We used surrogate measures of bone strength at the radius and tibia measured by peripheral quantitative computed tomography (pQCT) to evaluate their relationships with nonvertebral fracture risk. Femoral neck (FN) aBMD, measured by dual-energy X-ray absorptiometry (DXA), also was included. The study population consisted of 1143 white men aged 69+ years with pQCT measures at the radius and tibia from the Minneapolis and Pittsburgh centers of the Osteoporotic Fractures in Men (MrOS) study. Principal-components analysis and Cox proportional-hazards modeling were used to identify 21 of 58 pQCT variables with a major contribution to nonvertebral incident fractures. After a mean 2.9 years of follow-up, 39 fractures occurred. Men without incident fractures had significantly greater bone mineral content, cross-sectional area, and indices of bone strength than those with fractures by pQCT. Every SD decrease in the 18 of 21 pQCT parameters was significantly associated with increased fracture risk (hazard ration ranged from 1.4 to 2.2) independent of age, study site, body mass index (BMI), and FN aBMD. Using area under the receiver operation characteristics curve (AUC), the combination of FN aBMD and three radius strength parameters individually increased fracture prediction over FN aBMD alone (AUC increased from 0.73 to 0.80). Peripheral bone strength measures are associated with fracture risk and may improve our ability to identify older men at high risk of fracture.

    Prior studies suggest that increased urine albumin is associated with a heightened fracture risk in women, but results in men are unclear. We used data from Osteoporotic Fractures in Men (MrOS), a prospective cohort study of community-dwelling men aged ≥65 years, to evaluate the association of increased urine albumin with subsequent fractures and annualized rate of hip bone loss. We calculated albumin/creatinine ratio (ACR) from urine collected at the 2003-2005 visit. Subsequent clinical fractures were ascertained from triannual questionnaires and centrally adjudicated by review of radiographic reports. Total hip BMD was measured by DXA at the 2003-2005 visit and again an average of 3.5 years later. We estimated risk of incident clinical fracture using Cox proportional hazards models, and annualized BMD change using ANCOVA. Of 2982 men with calculable ACR, 9.4% had ACR ≥30 mg/g (albuminuria) and 1.0% had ACR ≥300 mg/g (macroalbuminuria). During a mean of 8.7 years of follow-up, 20.0% of men had an incident clinical fracture. In multivariate-adjusted models, neither higher ACR quintile (p for trend 0.75) nor albuminuria (HR versus no albuminuria, 0.89; 95% CI, 0.65 to 1.20) was associated with increased risk of incident clinical fracture. Increased urine albumin had a borderline significant, multivariate-adjusted, positive association with rate of total hip bone loss when modeled in ACR quintiles (p = 0.06), but not when modeled as albuminuria versus no albuminuria. Macroalbuminuria was associated with a higher rate of annualized hip bone loss compared to no albuminuria (-1.8% more annualized loss than in men with ACR fracture associations. In these community-dwelling older men, we found no association between urine albumin levels and risk of incident clinical fracture, but found a borderline significant, positive association with rate of hip bone loss. © 2016 American Society for Bone and Mineral Research. © 2016 American Society for Bone and

    The optimal approach for selecting men for bone mineral density (BMD) testing to screen for osteoporosis is uncertain. To compare strategies for selecting older men for screening BMD testing. Prospective cohort study. A total of 4043 community-dwelling men aged ≥70 years at four US sites. BMD at the total hip, femoral neck, and lumbar spine using dual-energy x-ray absorptiometry (DXA). Sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio, negative likelihood ratio, and area under the receiver operating curve (AUC) of the Osteoporosis Self-Assessment Tool (OST) and Fracture Risk Assessment Tool (FRAX) without BMD to discriminate between those with and without osteoporosis as defined by World Health Organization (WHO) diagnostic criteria, and between those recommended and not recommended for pharmacologic therapy based on the National Osteoporosis Foundation (NOF) guidelines. Among the cohort, 216 (5.3%) had a BMD T-score ≤ -2.5 at the femoral neck, total hip, or lumbar spine, and 1184 (29.2%) met criteria for consideration of pharmacologic therapy according to NOF guidelines. The OST had better discrimination (AUC 0.68) than the FRAX (AUC 0.62; p = 0.004) for identifying T-score-defined osteoporosis. Use of an OST threshold of <2 resulted in sensitivity of 0.83 and specificity of 0.36 for the identification of osteoporosis, compared to sensitivity of 0.59 and specificity of 0.59 for the use of FRAX with a cutoff of 9.3% 10-year risk of major osteoporotic fracture. The OST performs modestly better than the more complex FRAX in selecting older men for BMD testing to screen for osteoporosis; the use of either tool substantially reduces the proportion of men referred for BMD testing compared to universal screening. Of 1000 men aged 70 and older in this community-based cohort, the use of an OST cutoff of <2 to select men for BMD testing would result in 654 men referred for BMD testing, of whom 44 would be

    Elevated vertebral bone marrow fat (BMF) among individuals with osteoporosis has been established in histomorphometric studies. Several studies have found a negative correlation between BMF and bone mineral density (BMD) at the spine in men and women across different age groups. Animal studies have also observed bone loss with increased BMF in mice with induced diabetes. Our study objective was to test the hypothesis that the association between BMF and BMD varies by diabetic status. We performed a cross-sectional study of 156 men aged 74-96years from the Osteoporotic Fractures in Men study at the Pittsburgh clinical site. All men had spine BMF scans using proton magnetic resonance spectroscopy and spine and hip BMD scans by dual-energy X-ray absorptiometry. BMF was expressed as lipid to "lipid+water" ratio (%). Men were considered diabetic if they self-reported a physician diagnosis of diabetes, diabetes medication or had a fasting glucose ≥126mg/dl. Men with diabetes (n=38) had a significantly higher spine BMF (58.9 vs. 54.6%, p=0.0035), spine BMD (1.20 vs. 1.10g/cm(2), P=0.007) and total hip BMD (1.00 vs. 0.94g/cm(2), p=0.04) than those without, while no differences were observed for body weight, body mass index or waist circumference. Pearson correlation tests showed no significant correlation of spine BMF with age or BMD in non-diabetics. Significant inverse correlations were observed between BMF and BMD (-0.30 for femoral neck and -0.39 for total hip) among diabetic men. In conclusion, men with diabetes had a higher BMF compared to non-diabetic men. The correlation between BMF and BMD differed by diabetes status. Further investigation of the association of diabetes with BMF and BMD may provide a better understanding of the high fracture rates among individuals with diabetes despite their higher BMD.

    Full Text Available In men aged less than 60, the association of serum and urinary levels of biochemical bone turnover markers (BTMs and bone mineral density (BMD is weak or not significant. After this age, higher BTM levels are correlated weakly, but significantly, with lower BMD and faster bone loss. Limited data from the cohort studies suggest that BTM measurement does not improve the prediction of fragility fractures in older men in comparison with age, BMD, history of falls and fragility fractures. Testosterone replacement therapy (TRT decreases bone resorption. During TRT, bone formation markers slightly increase (direct effect on osteoblasts, then decrease (slowdown of bone turnover. Bisphosphonates (alendronate, risedronate, ibandronate, zoledronate induce a rapid decrease in bone resorption followed by a milder decrease in bone formation. In men receiving antiresorptive therapy for prostate cancer, zoledronate, denosumab and toremifene decrease significantly levels of bone resorption and bone formation markers. Teriparatide induced a rapid increase in serum concentrations of bone formation markers followed by an increase in bone resorption. We need more studies on the utility of BTM measurement for the improvement of the persistence and adherence to the anti-osteoporotic treatment in men.

    Accentuated kyphosis is associated with adverse health outcomes, including falls and fractures. Low bone density is a risk factor for hyperkyphosis, and each vertebral fracture adds roughly 4° to forward spine curvature. Sex steroids, in particular low bioavailable estradiol and high sex hormone-binding globulin (SHBG), are associated with bone loss and high SHBG is associated with vertebral fractures in older men. We, therefore, hypothesized that low bioavailable estradiol and high SHBG would be associated with worse kyphosis. To test this hypothesis, we examined the cross-sectional associations between individual bioavailable sex hormones and SHBG with radiographically assessed kyphosis. Participants included 1500 men aged 65 and older from the Osteoporotic Fractures in Men (MrOS) Study, in whom baseline measures of kyphosis and sex hormones were available. Modified Cobb angle of kyphosis, calculated from T4 through T12, was assessed from supine lateral spine radiographs. Serum total estradiol and total testosterone were measured by mass spectrometry, and bioavailable sex steroids were calculated from mass action equations. After adjustment for age and other confounding variables, no association was found between bioavailable estradiol or testosterone and Cobb angle, either when kyphosis was analyzed as a continuous variable or dichotomized into highest versus lower three quartiles. In linear regression models adjusted for age and clinic site, there was a significant association between SHBG and kyphosis (parameter estimate = 0.76 per SD increase, p = 0.01). In the fully adjusted model, this association was weakened and of only borderline statistical significance (parameter estimate = 0.61 per SD, p = 0.05). Logistic models demonstrated similar findings. Although associated with bone loss, we did not demonstrate that low bioavailable estradiol translates into worse kyphosis in older men. High SHBG is associated with bone loss and vertebral

    Full Text Available Abstract Research in the field of older gay men remains scarce. This exploratory study examines older gay men's experiences in the construction of family integrity (versus disconnection and alienation. The family integrity approach is a developmental perspective that links ego integrity to a larger process of constructing meaning within the family system. The sample comprises ten participants (from 60 to 88 years old. A semi-structured interview was conducted and submitted to content analysis. The main findings suggest three experiences in older gay men's construction of family integrity: (i influence of homosexuality throughout life; (ii establishing a family of choice; (iii creating a legacy associated with homosexuality. Family integrity in older gay men seems to evolve from disclosure at a young age to making homosexuality a legacy in old age.

    The knowledge about vitamin B(12) and folic acid levels in preserving bone mass in older men is limited. In this retrospective study, we aimed to find out whether levels of vitamin B(12) and folic acid are related to BMD in older men. Two hundred and sixty-nine older men were included in the study. Forty-two (15.6%) of them had osteoporotic, 150 (55.8%) had osteopenic, and 77 (28.6%) had normal BMD. Vitamin B(12) and folic acid levels were categorized as indicating normal, borderline, or low vitamin statuses. Femur neck densities showed statistically significant differences in subjects having low, borderline, and normal vitamin B(12), respectively. There were no significant differences between the three tertiles of vitamin B(12) in femur total, trochanteric, and intertrochanteric densities. After adjustment for age, body mass index (BMI), alcohol, smoking, and exercise with analysis of covariance, the difference was still statistically significant between two groups for femur neck density (p=0.011). No significant difference was observed between the groups of folic acid in any femur sites. We found that the normal level of vitamin B(12) in older men may be related to a decrease of femur neck bone loss. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

    This secondary analysis of qualitative interviews describes how older Swedish men approach the caregiver role for a wife with dementia, over time. An increasing number of male caregivers will become primary caregivers for partners living with dementia at home, and they will likely be caregivers for an extended period of time. It has been stated that caregiving experiences influence how older men think of themselves. The theoretical starting point is a constructivist position, offering an understanding of older caregiving men's constructions and reconstructions of themselves and their caregiver roles. Seven men, who were cohabiting with their wives, were interviewed on up to five occasions at home during a 5- to 6-year period. The findings comprise three themes; me and it, me despite it, it is me, depict how these men gradually take on and normalise the caregiving tasks, and how they develop and internalise a language based on their caring activities. The results provide understanding about the relationship between men as caregivers and how this influences them as individuals. By careful attention to each caregiving man's individual needs rather than making gendered assumptions about men and caring, the aim of the caregiver support for men might best target men's own meaning to the caring in their the everyday practices. © 2017 Nordic College of Caring Science.

  6. Bone Turnover Does Not Reflect Skeletal Aging in Older Hispanic Men with Type 2 Diabetes

    The paradox of fragility fracture in the presence of non-osteoporotic bone mineral density in older patients with type 2 diabetes mellitus (DM2) makes it difficult to clinically predict fracture in this vulnerable group. Serum osteocalcin (OC), a marker of bone turnover, increases with normal skeletal aging indicating risk of fracture. However, OC has been reported to be lower in patients with DM2. An inverse association between higher glycated hemoglobin levels (HbA1c) and lower serum OC in older DM2 patients triggered discussions encouraging further investigation. A key question to be answered is whether changes in glucose metabolism is responsible for bone metabolic changes, ultimately leading to increased risk of fragility fractures in DM2 patients. While these studies were conducted among Caucasian and Asian populations, this has not been studied in Hispanic populations who suffer from a higher prevalence of DM2. The Cameron County Hispanic Cohort (CCHC) in Texas is a homogeneous Hispanic cohort known to have high prevalence of DM2 (30%). Our preliminary data from this cohort reported OC levels lower than the suggested threshold for fragility fracture in post-menopausal women. We further investigated whether bone turnover in older CCHC adults with DM2 show a normal pattern of skeletal aging. Samples and data were obtained from a nested cohort of 68 (21 men and 47 women) Hispanic older adults (=50 years) who had a diagnosis of DM2. Given high prevalence of uncontrolled DM2 in this cohort, we divided population into two groups: i) poor DM2 control with HbA1c level =8 (48% men and 38% women) and ii) good DM2 control with HbA1c level <8). A crosssectional analysis documented associations between serum OC and age adjusted HbA1c levels. There was no direct association between age and OC concentrations in our study. Higher HbA1c was associated with lower serum OC in men (odds ratio -6.5, 95% confidence interval -12.7 to - 0.3, p < 0.04). No significant associations

    The most consistent biodemographic correlate of sexual orientation in men is the number of older brothers (fraternal birth order). The mechanism underlying this effect remains unknown. In this article, I provide a direct test pitting prenatal against postnatal (e.g., social/rearing) mechanisms. Four samples of homosexual and heterosexual men (total n = 944), including one sample of men raised in nonbiological and blended families (e.g., raised with half- or step-siblings or as adoptees) were studied. Only biological older brothers, and not any other sibling characteristic, including nonbiological older brothers, predicted men's sexual orientation, regardless of the amount of time reared with these siblings. These results strongly suggest a prenatal origin to the fraternal birth-order effect.

    Late-onset hypogonadism is an underdiagnosed and easily treated condition defined by low serum testosterone levels in men older than 65 years. When treated, a significant improvement in quality of life may be reached in this rapidly rising sector of the population. During the evaluation, laboratory tests and a full medication review should be performed to exclude other illnesses or adverse effects from medications. The major goal of treatment in this population is treating the symptoms related to hypogonadism. There has not been clear evidence supporting universally giving older men with low serum testosterone levels and hypogonadal symptoms testosterone replacement therapy.

    Hip fracture risk is known to be related to material properties of the proximal femur, but fracture prediction studies adding richer quantitative computed tomography (QCT) measures to dual-energy X-ray (DXA)-based methods have shown limited improvement. Fracture types have distinct relationships to predictors, but few studies have subdivided fracture into types, because this necessitates regional measurements and more fracture cases. This work makes use of cortical bone mapping (CBM) to accurately assess, with no prior anatomical presumptions, the distribution of properties related to fracture type. CBM uses QCT data to measure the cortical and trabecular properties, accurate even for thin cortices below the imaging resolution. The Osteoporotic Fractures in Men (MrOS) study is a predictive case-cohort study of men over 65 years old: we analyze 99 fracture cases (44 trochanteric and 55 femoral neck) compared to a cohort of 308, randomly selected from 5994. To our knowledge, this is the largest QCT-based predictive hip fracture study to date, and the first to incorporate CBM analysis into fracture prediction. We show that both cortical mass surface density and endocortical trabecular BMD are significantly different in fracture cases versus cohort, in regions appropriate to fracture type. We incorporate these regions into predictive models using Cox proportional hazards regression to estimate hazard ratios, and logistic regression to estimate area under the receiver operating characteristic curve (AUC). Adding CBM to DXA-based BMD leads to a small but significant (p fracture, with AUC increasing from 0.78 to 0.79, assessed using leave-one-out cross-validation. For specific fracture types, the improvement is more significant (p fractures and 0.76 to 0.82 for femoral neck fractures. In contrast, adding DXA-based BMD to a CBM-based predictive model does not result in any significant improvement. © 2015 The Authors. Journal of Bone and Mineral Research published by

    Full Text Available Low levels of testosterone are manifested by erectile dysfunction, reduced sexual desire, and loss of morning erections with increasing numbers of men are being diagnosed and require treatment. The prevalence rates of testosterone deficiency vary according to different studies but may be as high as 40% in populations of patients with type 2 diabetes. There is increasing evidence that testosterone deficiency is associated with increased cardiovascular and all-cause mortality. Screening for low testosterone is recommended in a number of high risk groups including those with type 2 diabetes and metabolic syndrome. There are recent data to suggest that testosterone replacement therapy may reduce cardiovascular mortality as well as improving multiple surrogate markers for cardiovascular events. Specific clinical trials of testosterone replacement therapy are needed in selected populations but in the meantime we must treat patients based on the best current evidence.

This study assessed this training method in healthy older (45–60 years. men. Initially, 35 older men performed an incremental isometric exercise test to determine the linearity of the heart rate versus percentage peak EMG (%EMGpeak and systolic blood pressure versus %EMGpeak relationship. Thereafter, 20 participants were allocated to a training or control group. The training group performed three double-leg isometric sessions per week for 8 weeks, at 85% of peak heart rate. The training resulted in a significant reduction in resting systolic (11 ± 8 mmHg, P < 0.05 and mean arterial (5 ± 7 mmHg, P < 0.05 blood pressure. There was no significant change in resting systolic blood pressure for the control group or diastolic blood pressure in either group (all P > 0.05. These findings show that this training method, used previously in young men, is also effective in reducing resting systolic and mean arterial blood pressure in older men.Keywords: electromyography, resting blood pressure, heart rate

    Low bone mineral density (BMD) increases fracture risk; how changes in BMD influence fracture risk in older men is uncertain. BMD was assessed at two to three time points over 4.6 years using dual-energy X-ray absorptiometry (DXA) for 4470 men aged ≥65 years in the Osteoporotic Fractures in Men (MrOS) Study. Change in femoral neck BMD was estimated using mixed effects linear regression models. BMD change was categorized as "accelerated" (≤-0.034 g/cm(2) ), "expected" (between 0 and -0.034 g/cm(2) ), or "maintained" (≥0 g/cm(2) ). Fractures were adjudicated by central medical record review. Multivariate proportional hazards models estimated the risk of hip, nonspine/nonhip, and nonspine fracture over 4.5 years after the final BMD measure, during which time 371 (8.3%) men experienced at least one nonspine fracture, including 78 (1.7%) hip fractures. Men with accelerated femoral neck BMD loss had an increased risk of nonspine (hazard ratio [HR] = 2.0; 95% confidence interval [CI] 1.4-2.8); nonspine/nonhip (HR = 1.6; 95% CI 1.1-2.3); and hip fracture (HR = 6.3; 95% CI 2.7-14.8) compared with men who maintained BMD over time. No difference in risk was seen for men with expected loss. Adjustment for the initial BMD measure did not alter the results. Adjustment for the final BMD measure attenuated the change in BMD-nonspine fracture and the change in BMD-nonspine/nonhip relationships such that they were no longer significant, whereas the change in the BMD-hip fracture relationship was attenuated (HR = 2.6; 95% CI 1.1-6.4). Total hip BMD change produced similar results. Accelerated decrease in BMD is a strong, independent risk factor for hip and other nonspine fractures in men.

    Young African-American (AA) men who have sex with men (YAAMSM) have experienced the greatest proportional increase in new HIV cases compared with other groups. Bridging sexual partnerships between YAAMSM and older aged cohorts with higher rates of primary HIV infection has emerged as an important independent risk factor for the development of HIV. We explored reasons young AAMSM cite for being attracted to and seeking an older partner and the interpersonal needs met within older sexual partnerships. Seventeen in-depth semistructured qualitative interviews were conducted in YAAMSM residing in a midsized urban city with high HIV prevalence. Two coders independently evaluated transcribed data to identify/collapse codes that emerged. We analyzed data using categorical and contextualizing analytic methods. Two themes emerged from the text for seeking an older sexual partner: the emotional maturity the older partner represented and the ability of the older partner to expose the younger partner to more life experiences. In addition, two themes emerged around attraction: support and physical attractiveness of the older partner. Few men described seeking age-discordant relationships for the sole purpose of exchange sex. Older partners during first same-sex experience helped younger partners sort through sexual position and how to perform in relationships. These interviews suggest that YAAMSM may be seeking older partners to fulfill desires to be in a stable, emotionally mature relationship and for exposure in the larger community. Prevention strategies aimed at targeting adolescent MSM age-discordant relationships will need to address the interpersonal needs met within older sexual partnerships.

    Osteoporosis-related fractures constitute a major health concern not only in women but also in men. Insulin-like growth factor 1 (IGF-1) is a key determinant of bone mass, but the association between serum IGF-1 and incident fractures in men remains unclear. To determine the predictive value of serum IGF-1 for fracture risk in men, older men (n = 2902, mean age of 75 years) participating in the prospective, population-based Osteoporotic Fractures in Men (MrOS) Sweden study were followed for a mean of 3.3 years. Serum IGF-1 was measured at baseline by radioimmunoassay. Fractures occurring after the baseline visit were validated. In age-adjusted hazards regression analyses, serum IGF-1 associated inversely with risk of all fractures [hazard ratio (HR) per SD decrease = 1.23, 95% confidence interval (CI) 1.07-1.41], hip fractures (HR per SD decrease = 1.45, 95% CI 1.07-1.97), and clinical vertebral fractures (HR per SD decrease = 1.40, 95% CI 1.10-1-78). The predictive role of serum IGF-1 for fracture risk was unaffected by adjustment for height, weight, prevalent fractures, falls, and major prevalent diseases. Further adjustment for bone mineral density (BMD) resulted in an attenuated but still significant association between serum IGF-1 and fracture risk. Serum IGF-1 below but not above the median was inversely related to fracture incidence. The population-attributable risk proportion was 7.5% for all fractures and 22.9% for hip fractures. Taken together, older men with low serum IGF-1 have an increased fracture risk, especially for the two most important fracture types, hip and vertebral fractures. The association between serum IGF-1 and fracture risk is partly mediated via BMD.

We examined these issues in a study of older British men. Methods Cross-sectional study of 4252 men aged 60–79 years selected from one socially representative general practice in each of 24 British towns and who attended for examination between 1998 and 2000.

Analyses were based on 3603 men measured in or close to ( Results The COHb distribution was positively skewed. Geometric mean COHb level was 0.46% and the median 0.50%; 9.2% of men had a COHb level of 2.5% or more and 0.1% of subjects had a level of 7.5% or more. Factors which were independently related to mean COHb level included season (highest in autumn and winter, region (highest in Northern England, gas cooking (slight increase and central heating (slight decrease and active smoking, the strongest determinant. Mean COHb levels were more than ten times greater in men smoking more than 20 cigarettes a day (3.29% compared with non-smokers (0.32%; almost all subjects with COHb levels of 2.5% and above were smokers (93%. Pipe and cigar smoking was associated with more modest increases in COHb level. Passive cigarette smoking exposure had no independent association with COHb after adjustment for other factors. Active smoking accounted for 41% of variance in COHb level and all factors together for 47%. Conclusion An appreciable proportion of men have COHb levels of 2.5% or more at which symptomatic effects may occur, though very high levels are uncommon. The results confirm that smoking (particularly cigarette smoking is the dominant influence on COHb levels.

    Synthetic salmon calcitonin at a dose of 100 MRC units daily was administered to nine biopsy-proven osteoporotic men, aged 50 years and older, for one to two years. Two additional groups of men with comparable degrees of osteoporosis received either multivitamins alone or multivitamins plus a calcium supplement. The group treated with salmon calcitonin increased their total body calcium by 3% at the end of two years, whereas no change was seen in the other two groups. This result was not statistically significant because of dispersion of the data. There was also no significant changes in bone mineral content of the distal forearm. Four of the nine men treated with calcitonin had increases in total body calcium, which exceeded the reproducibility of the in vivo neutron activation method by 2 SD (SD +- 1.1%). The mean increase in total body calcium in these four patients was 8% compared to a mean decrease of 2 to 4% in the remainder. New vertebral compression and/or collapse was significantly less frequent in the group treated with calcitonin (1.0 +- 0.6 per patient) compared to the other two groups (2.4 +- 0.8 and 2.0 +- 0.6 per patient). These data support the thesis that calcitonin can increase skeletal mass in selected osteoporotic patients and justify further studies to detect responsive patients and to amplify the effect of calcitonin in such patients. 5 references.

    We used data from the Osteoporotic Fractures in Men (MrOS) study to test the hypothesis that men with higher levels of bone turnover would have accelerated bone loss and an elevated risk of fracture. MrOS enrolled 5995 subjects >65 yr; hip BMD was measured at baseline and after a mean follow-up of 4.6 yr. Nonspine fractures were documented during a mean follow-up of 5.0 yr. Using fasting serum collected at baseline and stored at -190 degrees C, bone turnover measurements (type I collagen N-propeptide [PINP]; beta C-terminal cross-linked telopeptide of type I collagen [betaCTX]; and TRACP5b) were obtained on 384 men with nonspine fracture (including 72 hip fractures) and 947 men selected at random. Among randomly selected men, total hip bone loss was 0.5%/yr among those in the highest quartile of PINP (>44.3 ng/ml) and 0.3%/yr among those in the lower three quartiles (p = 0.01). Fracture risk was elevated among men in the highest quartile of PINP (hip fracture relative hazard = 2.13; 95% CI: 1.23, 3.68; nonspine relative hazard = 1.57, 95% CI: 1.21, 2.05) or betaCTX (hip fracture relative hazard = 1.76, 95 CI: 1.04, 2.98; nonspine relative hazard = 1.29, 95% CI: 0.99, 1.69) but not TRACP5b. Further adjustment for baseline hip BMD eliminated all associations between bone turnover and fracture. We conclude that higher levels of bone turnover are associated with greater hip bone loss in older men, but increased turnover is not independently associated with the risk of hip or nonspine fracture.

    Excess thyroid hormone is associated with increased bone loss and fracture risk in older women, but few data exist for men. We sought to determine if thyroid function is independently associated with bone loss and fracture risk in older men. Data were analyzed from the Osteoporotic Fractures in Men (MrOS) study, a cohort of community-dwelling U.S. men aged 65 years and older. Using a case-cohort design, fasting baseline serum archived at -80°C was assayed for thyroid-stimulating hormone (thyrotropin) (TSH) and free thyroxine (FT4) in 397 men with confirmed nonspine fracture, including 157 hip fractures, and 1420 randomly selected men without fracture. TSH and FT4 were analyzed as continuous variables and as thyroid function categories (subclinical hyperthyroid, euthyroid, and subclinical hypothyroid). Hip dual-energy X-ray absorptiometry (DXA) (Hologic QDR4500) was measured at baseline and after a mean follow-up of 4.6 years. Incident nonspine fractures were centrally adjudicated. Bone loss was evaluated with multivariate regression methods and fractures risk was evaluated using hazard models that accounted for the case-cohort sampling, adjusted for age, clinic-site, body mass index (BMI), race, physical activity, corticosteroid use, smoking, alcohol intake, and thyroid medication use. In fully adjusted analyses, TSH was not associated with risk of nonspine fracture (relative hazard [RH] 0.92 per SD decrease in TSH; 95% confidence interval [CI], 0.74-1.14), but was significantly associated with risk of hip fracture (RH 1.31; 95% CI, 1.01-1.71), which persisted among normal range TSH values (RH 1.21; 95% CI, 1.00-1.47). There was no association between TSH or FT4 and bone loss, and fracture risk did not differ significantly by thyroid function category. We conclude that although neither TSH nor FT4 are associated with bone loss, lower serum TSH may be associated with an increased risk of hip fractures in older men.

    The purpose of the study was to determine if leg strength limits VO2 max and the ability to reach a plateau during VO2 max test in older men during cycle ergometry. Men aged 70-80 years were randomly selected into a strength training (ST, n=12) 3 times weekly for 16 weeks, followed by 4 weeks detraining or a non-training control group (C, n=12). Leg strength and VO2 max were assessed every 4 weeks for 20 weeks; body composition and cardiac function were assessed before and after 16 weeks training and after 4 weeks detraining. Leg strength, upper leg muscle mass (ULMM), arterial-venous O2 difference (a-v O2 difference) and VO2 max increased in the ST group (95±0.6%, 7±0.7%. 6.2±0.5% and 8±0.8%, respectively; PVO2 max and a-v O2 difference returned to pre-training levels. There was no change in the ability of the participants to reach a plateau during VO2 max testing over the 20-week study. These findings indicate that leg strength may not limit either VO2 max or the ability to plateau during VO2 max tests in older men during cycle ergometry. © Georg Thieme Verlag KG Stuttgart · New York.

    @@ Two manuscripts were recently published in the New England Journal of Medicine [1, 2] that re-late to testosterone deficiency and treatment in older men. To many readers, both these studies will seem to be dealing with the same topic in a complementary manner: the first [ 1 ] looks at how to define an illness and the second [2] looks at how to treat it (or maybe not treat it). If perceived as having stringent logical (and clinical) progression, these papers could have a major impact not only on andrology but on medicine in general.

    Full Text Available OBJECTIVES: To assess erectile function in middle-aged and older men with asexuality status and further analyze their specific reasons for this condition. SUBJECTS AND METHODS: Men who had regular sexual intercourse attempts (sex frequency ≥ 1 time per month were classified into mild erectile dysfunction (ED, moderate to severe ED and non-ED according to International Index of Erectile Function-5, and men having no sexual intercourse attempts for at least 6 months were defined as having an asexuality status. The risk factors associated with ED were collected in a sample of 1,531 Chinese men aged 40 to 80 years, and the self-report reasons for asexuality were recorded in asexual cohort individually. Comparative analyses and multivariate regression models were conducted among these groups. RESULTS: The prevalence rates of ED and asexuality status were 49.9% and 37.2%. The asexuality status group had higher risk factors than the moderate to severe ED group in terms of old age (age ≥ 65, adjusted odds ratio (OR 17.69 versus (Vs. 7.19, diabetes (crude OR: 2.40 Vs. 2.36 and hypertension (crude OR: 1.78 Vs. 1.72. The specific reasons for the asexuality status were "erectile difficulty" (52.9%, "do not care about sexuality" (53.5%", "no longer necessary to have sexuality at this age" (47.7%, "severe stress" (44.4%, "severe fatigue" (26.3% and "masturbation" (26.9%. CONCLUSIONS: Men with an asexual status suffer from higher risk factors for ED than men with moderate to severe ED. The majority of this asexual status could be attributed to a full ED, although the reasons for this transient asexuality also involved sexual attitudes and interests, sexual partners and masturbation.

    Frailty is common in the elderly and predisposes to ill-health. Some symptoms of frailty overlap those of thyroid dysfunction, but it is unclear whether differences in thyroid status influence risk of frailty. We evaluated associations between thyroid status and frailty in older men. Cross-sectional epidemiological study. Community-dwelling men aged 70-89 years. Circulating thyrotropin (TSH) and free thyroxine (FT(4) ) were assayed. Frailty was assessed as ≥3 of the Fatigue, Resistance, Ambulation, Illnesses and Loss (FRAIL) scale's 5 domains: fatigue; resistance (difficulty climbing flight of stairs); ambulation (difficulty walking 100 m); illness (>5); or weight loss (>5%), blinded to hormone results. Of 3943 men, 27 had subclinical hyperthyroidism, 431 subclinical hypothyroidism and 608 were classified as being frail (15·4%). There was an inverse log-linear association of TSH with FT(4). There was no association between TSH and frailty. After adjusting for covariates, men with FT(4) in the highest two quartiles had increased odds of being frail (Q3:Q1, odds ratio [OR] = 1·32, 95% confidence interval [CI] = 1·01-1·73 and Q4:Q1, OR = 1·36, 95% CI = 1·04-1·79, P = 0·010 for trend). Higher FT(4) was associated with fatigue (P = 0·038) and weight loss (P < 0·001). The association between FT(4) and frailty remained significant when the analysis was restricted to euthyroid men. High-normal FT(4) level is an independent predictor of frailty among ageing men. This suggests that even within the euthyroid range, circulating thyroxine may contribute to reduced physical capability. Further studies are needed to clarify the utility of thyroid function testing and the feasibility of preventing or reversing frailty in older men. © 2012 Blackwell Publishing Ltd.

    We evaluated the associations between loneliness and subjective appraisals of marital relationship as well as reciprocal associations of loneliness in married men and women. The Health and Retirement Study is a national survey of older adults over the age of 50, residing in the US. This study is based on a paper and pencil questionnaire administered in the year 2006. Overall, 2723 couples completed this questionnaire. Loneliness was evaluated using the three-item version of the Revised University of California Los Angeles Loneliness Scale. A non-recursive path analysis was conducted. The model suggested that subjective appraisals of the relationship with spouse play a major role in one's sense of loneliness. In addition, loneliness in men and women shares reciprocal associations. The model explained 24% and 29% of the variability in loneliness reported by married men and women, respectively. Results indicate that capitalizing and enhancing one's social life might also be beneficial for his or her partner. Any intervention to alleviate loneliness in married couples has to take into consideration their perceived marital relationship as well as the reciprocal associations of loneliness in married men and women.

    To determine if older men who use computers have lower risk of developing dementia. Cohort study of 5506 community-dwelling men aged 69 to 87 years followed for up to 8.5 years. Use of computers measured as daily, weekly, less than weekly and never. Participants also reported their use of email, internet, word processors, games or other computer activities. The primary outcome was the incidence of ICD-10 diagnosis of dementia as recorded by the Western Australian Data Linkage System. 1857/5506 (33.7%) men reported using computers and 347 (6.3%) received a diagnosis of dementia during an average follow up of 6.0 years (range: 6 months to 8.5 years). The hazard ratio (HR) of dementia was lower among computer users than non-users (HR = 0.62, 95%CI = 0.47-0.81, after adjustment for age, educational attainment, size of social network, and presence of depression or of significant clinical morbidity). The HR of dementia appeared to decrease with increasing frequency of computer use: 0.68 (95%CI = 0.41-1.13), 0.61 (95%CI = 0.39-0.94) and 0.59 (95%CI = 0.40-0.87) for less than weekly, at least weekly and daily. The HR of dementia was 0.66 (95%CI = 0.50-0.86) after the analysis was further adjusted for baseline cognitive function, as measured by the Mini-Mental State Examination. Older men who use computers have lower risk of receiving a diagnosis of dementia up to 8.5 years later. Randomised trials are required to determine if the observed associations are causal.

Age was inversely correlated with WBBMD (r = -0.20 and FNBMD (r = -0.21 but not with LSBMD (r = 0.03. Body mass index and weight showed a strong positive correlation with WBBMD (r = 0.48 and 0.54, LSBMD (r = 0.37 and 0.45 and FNBMD (r = 0.42 and 0.48. Correlation with height was positive but weaker. No significant bone loss at the lumbar spine level was observed as the population aged. FNBMD and WBBMD decreased significantly only in the last decade (age 70-79 studied. BMD was higher for Brazilian men as compared to Brazilian women at all sites. No significant differences were observed between Brazilian and the US/European male population for BMD in the femoral neck. BMD measured by dual-energy X-ray absorptiometry in South American men is reported here for the first time. A decrease in FNBMD was detected only later in life, with a pattern similar to that described for the US/European male population.

    Fracture risk is determined by bone strength and the risk of falls. The relationship between serum sex steroids and bone strength parameters in men is well known, whereas the predictive value of sex steroids for falls is less studied. The aim of this study was to assess the associations between serum testosterone (T) and estradiol (E2) and the likelihood of falls. Older men (aged ≥65 years) from the United States (n = 1919), Sweden (n = 2495), and Hong Kong (n = 1469) participating in the Osteoporotic Fractures in Men Study had baseline T and E2 analyzed by mass spectrometry. Bioavailable (Bio) levels were calculated using mass action equations. Incident falls were ascertained every 4 months during a mean follow-up of 5.7 years. Associations between sex steroids and falls were estimated by generalized estimating equations. Fall rate was highest in the US and lowest in Hong Kong (US 0.50, Sweden 0.31, Hong Kong 0.12 fall reports/person/year). In the combined cohort of 5883 men, total T (odds ratio [OR] per SD increase = 0.88, 95% confidence interval [CI] 0.86-0.91) and BioT (OR = 0.86, 95% CI 0.83-0.88) were associated with incident falls in models adjusted for age and prevalent falls. These associations were only slightly attenuated after simultaneous adjustment for physical performance variables (total T: OR = 0.94, 95% CI 0.91-0.96; BioT: OR = 0.91, 95% CI 0.89-0.94). E2, BioE2, and sex hormone-binding globulin (SHBG) were not significantly associated with falls. Analyses in the individual cohorts showed that both total T and BioT were associated with falls in MrOS US and Sweden. No association was found in MrOS Hong Kong, and this may be attributable to environmental factors rather than ethnic differences because total T and BioT predicted falls in MrOS US Asians. In conclusion, low total T and BioT levels, but not E2 or SHBG, are associated with increased falls in older men. © 2017 American Society for Bone and Mineral Research.

    Mangweth-Matzek, Barbara; Hoek, Hans W

    2017-08-18

    We summarized recent literature on the epidemiology and treatment of eating disorders in middle-aged and older women and men. The prevalence of eating disorders according to DSM-5 criteria is around 3.5% in older (>40 years) women and around 1-2% in older men. The majority of those eating disordered persons are not in treatment. There are new terms like 'perimenopausal eating disorders' and 'muscularity-oriented eating disorders' indicating the impact of the aging process and sex-specific differences. Disordered eating and eating disorders occur in both women and men of all ages. Medical complications because of age, the stigma of eating disorders in a still 'untypical' age, and the glorification of sports activity often hinder the recognition of eating disorders in midlife and older persons. Treatment approaches should consider treatment strategies tailored for older women and men, addressing the context of midlife and aging.

    Objective: To investigate the correlation between serum Omentin-1 levels and the presence of osteoporosis in older men. Methods: Serum Omentin-1, bone turnover biochemical markers, and bone mineral density (BMD) were determined in 45 older men with osteoporosis or 45 older men without osteoporosis (65e70 years old). Results: Omentin-1 levels were increased in older men with osteoporosis, and the differences remained significant after con-trolling for fat mass. Omentin-1 was negatively correlated with BMD. In a multiple linear stepwise regression analysis, Omentin-1, lean mass, but not fat mass, were independent predictors of BMD for the combined group. Significant negative correlations between Omentin-1 and bone-specific alkaline phosphatase (BAP) and bone cross-linked N-telopeptides of typeⅠcollagen (NTX) were found. Omentin-1 was also independently associated with BMD and bone turnover markers in older men with osteoporosis and control groups that were considered separately. Conclusions: Omentin-1 is an independent predictor of BMD in older men with osteoporosis, and it is negatively correlated with bone turnover biochemical markers. It is suggested that Omentin-1 may exert a negative effect on bone mass through the regulation of the osteoblast differentiation in the older men with osteoporosis.

  1. Changes in community mobility in older men and women. A 13-year prospective study.

    Full Text Available Community mobility, defined as "moving [ones] self in the community and using public or private transportation", has a unique ability to promote older peoples' wellbeing by enabling independence and access to activity arenas for interaction with others. Early predictors of decreased community mobility among older men and women are useful in developing health promoting strategies. However, long-term prediction is rare, especially when it comes to including both public and private transportation. The present study describes factors associated with community mobility and decreased community mobility over time among older men and women. In total, 119 men and 147 women responded to a questionnaire in 1994 and 2007. Respondents were between 82 and 96 years old at follow-up. After 13 years, 40% of men and 43% of women had decreased community mobility, but 47% of men and 45% of women still experienced some independent community mobility. Cross-sectional independent community mobility among men was associated with higher ratings of subjective health, reporting no depression and more involvement in sport activities. Among women, cross-sectional independent community mobility was associated with better subjective health and doing more instrumental activities of daily living outside the home. Lower subjective health predicted decreased community mobility for both men and women, whereas self-reported health conditions did not. Consequently, general policies and individual interventions aiming to improve community mobility should consider older persons' subjective health.

    Objectives To test the hypothesis that men and women with both low bone mineral density and sarcopenia have a higher risk of fracture than those with only one or neither conditions. Design The Osteoporotic Fractures in Men study and the Study of Osteoporotic Fractures in women are prospective observational studies with a mean follow up of 9 years (2000–2012) and 8years (1997–2009) respectively. Setting US clinical centers Participants 5,544 men (mean age=73.7 years) and 1,114 women (mean age=77.6 years); all ≥age 65; able to walk without assistance, and without bilateral hip replacement. Measurements Sarcopenia was defined as low appendicular lean mass plus either slowness or weakness; and low bone mineral density, by the World Health Organization definition of T-scoresarcopenia (N=3367 men, 308 women); sarcopenic only (N=79 men; 48 women); low bone mineral density only (N=1986 men; 626 women), and low bone mineral density and sarcopenic (N=112 men; 132 women). Results Compared to men with normal bone mineral density and no sarcopenia, the Hazard ratio [HR] for fracture was 3.79 (95% confidence interval [CI], 2.65–5.41) among men with low bone mineral density and sarcopenia, 1.67 (95% CI, 1.45–1.93) among men with low bone mineral density only, and 1.14 (95% CI, 0.62–2.09) among men with sarcopenia only. Women with low bone mineral density and sarcopenia (HR, 2.27; 95% CI, 1.37–3.76), and women with low bone mineral density alone (HR, 2.62; 95% CI, 1.74–3.95), but not women with only sarcopenia had increased risk of fracture compared to normal women. Conclusion Men with both low bone mineral density and sarcopenia are at especially high risk of fracture. PMID:26310882

    2003-09-01

    Sex differences in fatigue resistance of the adductor pollicis (AP) muscle were studied in 24 older adults who were divided into three groups: 12 older men (69.8 +/- 4.60 years), 6 older women not on hormone replacement therapy (HRT) (70.2 +/- 4.02 years), and 6 older women on HRT (68.7 +/- 6.47 years). Fatigue in the AP muscle was induced using an intermittent (5 s contraction, 5 s rest) submaximal voluntary contraction (50% of maximal voluntary contraction (MVC)) protocol, which was continued until exhaustion (i.e., when subjects could either no longer maintain a 5-s contraction at 50% MVC or when the MVC was deemed to be lower than the target force). There was no effect of HRT on MVC or time to fatigue (TTF); therefore, the older women were pooled as one subject group. At baseline, men were stronger than women for MVC (75.9 +/- 18.8 N in men vs. 56.8 +/- 10.0 N in women; P 0.20), nor was there a significant relationship between baseline muscle force and TTF (r = 0.14). There was also no difference in the pattern of fatigue and recovery between the men and women. These results suggest that there is no difference in endurance or fatigue characteristics of the AP muscle in men and women over the age of 65 years, and that baseline muscle force does not predict fatigue resistance in this muscle.

    The study of major life events and their effects on well-being has considerable relevance for scientific disciplines and policy making in understanding the consumer behaviour of older people. There is evidence of differences in reactions to and coping with stress between males and females but relatively little knowledge about such gender differences amongst older people, especially in middle-income countries. This study of older Malaysians looked at both coping strategies and gender differences in reactions to stress when people are confronted with certain life events. Seventeen major life events were used in interviews with 645 respondents aged 50 years or older in five major urban areas in Peninsular Malaysia. The analysis showed older women tended to experience higher levels of chronic stress than older men. They also had more health problems, had lower levels of self-esteem and were less satisfied with life. Whilst the results showed little support for gender differences in coping behaviours, stress had a significant influence on the way older men and women change store preferences. A hypothesis that older women would use more emotion-focused coping strategies was not supported. Knowledge of how older Malaysians cope with life events and stress and especially in this instance with regard to consumption behaviour, is likely to be of considerable academic and policy related interest.

    Osteoporosis per se is not a harmful disease. It is the sequela of osteoporosis and most particularly the occurrence of osteoporotic fracture that makes osteoporosis a serious medical condition. All of the preventative measures, investigations, treatment and research into osteoporosis have one primary goal and that is to prevent the occurrence of osteoporotic fracture. Vertebral fracture is by far and away the most prevalent osteoporotic fracture. The significance and diagnosis of vertebral f...

  10. "Macho men" and preventive health care: implications for older men in different social classes.

    Springer, Kristen W; Mouzon, Dawne M

    2011-06-01

    The gender paradox in mortality--where men die earlier than women despite having more socioeconomic resources--may be partly explained by men's lower levels of preventive health care. Stereotypical notions of masculinity reduce preventive health care; however, the relationship between masculinity, socioeconomic status (SES), and preventive health care is unknown. Using the Wisconsin Longitudinal Study, the authors conduct a population-based assessment of masculinity beliefs and preventive health care, including whether these relationships vary by SES. The results show that men with strong masculinity beliefs are half as likely as men with more moderate masculinity beliefs to receive preventive care. Furthermore, in contrast to the well-established SES gradient in health, men with strong masculinity beliefs do not benefit from higher education and their probability of obtaining preventive health care decreases as their occupational status, wealth, and/or income increases. Masculinity may be a partial explanation for the paradox of men's lower life expectancy, despite their higher SES.

    Older prisoners are the fastest growing group of prisoners in most countries. They have high rates of physical and psychiatric co-morbidity, compared to community dwelling older persons and also compared with other prisoner groups. Very high rates of mental illness have been found in remand (pre-trial) prisoners when compared with other prisoner groups; however to date there have been no studies examining older male and female remand prisoners. A retrospective chart review was conducted of all remands, to a male and a female prison, over a six and half-year period. Demographic data were collected pertaining to psychiatric and medical diagnoses and seriousness of offending. We found rising numbers of older prisoners amongst male remand prisoners. Older remand prisoners had very high rates of affective disorder and alcohol misuse. They had rates of psychotic illnesses and deliberate self-harm comparable to younger remand prisoners. High rates of vulnerability were found among older prisoners and older prisoners had a greater need for general medical and psychiatric services than younger prisoners. We also found comparable offending patterns with younger prisoners and high rates of sexual offending among the older male prisoner group. Given the ageing population of many countries it is likely the numbers of older prisoners will continue to grow and given their high levels of both physical and psychiatric illness this will have implications for future service delivery.

    Male hypogonadism, defined as clinical features of androgen deficiency combined with confirm-ed unequivocally low testosterone levels [1], is a straightforward diagnosis in younger men with underlying testicular and pituitary pathology. The diagnosis of hypogo-nadism in older men is challenging,because of the non-specificity of symptoms and the age-related decline in testosterone levels which is accelerated by chronic disease and obesity.

    Full Text Available This article presents the results of a multidisciplinary study which investigated the effects of a period with floorball training on health status, psychological health and social capital of older men. Thirty-nine untrained men aged 69.9 ± 0.6 (range: 65–76 were randomized into a group playing floorball (n = 22 or a group playing petanque (n = 17 one hour twice a week for 12 weeks. Both groups filled out the Health Survey Short Form (SF-12 and the Hospital Anxiety and Depression Scale (HADS before and after the 12-week intervention. Linear regression analyses with bootstrapping showed that the men in the floorball group improved in the SF-12 composite score for mental health, as well as the HADS subscales anxiety and depression, compared to the men in the petanque group. In addition, 21 interviews were conducted with a sample of the men engaged in floorball. According to the statements in the interviews, the men in the floorball group experienced a high degree of solidarity and group cohesion which seemed to have increased their social capital during the intervention. In particular, the fun and joyful experiences of playing led to a high degree of social connectedness, which were mentioned by many of the men as the main reason for their participation throughout the 12-week period. The statistical results and the interview findings suggest that participation in a ball game such as floorball has several benefits regarding health status, psychological health and social capital and in addition that playing floorball is experienced as enjoyable amongst older men. Thus, it can be concluded that floorball is an activity that benefits older men and should be provided in relevant contexts, such as e.g. sport clubs or centres for seniors.

    We examined correlations between echo intensity and muscle strength and endurance. Rectus femoris echo intensity, maximal voluntary contraction (MVC) force and time to task failure during a 50% MVC task were determined for 12 younger (mean age = 25 y) and 13 older (mean age = 74 y) men. Bivariate correlations between echo intensity and normalized MVC force were similar for younger and older men, but was only statistically significant for the latter (younger r = -0.559, p = 0.059; older r = -0.580, p = 0.038). When all patients were combined, the correlation was significant (r = -0.733, p correlations were not observed for time to task failure (younger r = -0.382, p = 0.221; older r = -0.347, p = 0.246; all patients r = -0.229, p = 0.270). Rectus femoris echo intensity is associated with muscle strength, but not endurance, in younger and older men. Copyright © 2017 World Federation for Ultrasound in Medicine & Biology.

    A convenience sample of 176 healthy, community-dwelling, inactive older adults (mean age 70 ± 5 years; 62 males, 114 females) were tracked for one year. The purpose was to describe the exercise modality choices older adults make one year following participation in an exercise and education intervention. Telephone follow-up contacted 137 participants (78%, men = 50, women = 87) and 62% of the men and 69% of the women reported to be "currently exercising." Exercising independently was the most common type of exercise reported by 81% and 64% of men and women, respectively. Walking was the most commonly reported modality by both genders. The setting of exercise was most often reported to be at home or outside for both men and women. The main reason for continued participation at 12 months was for overall health (50% of men and 40% of women). Little variation was observed for exercise modality choice. Future interventions should consider a variety of exercise and physical activity opportunities for older adults.

  1. Andropause or male menopause? Rationale for testosterone replacement therapy in older men with low testosterone levels.

    Cunningham, Glenn R

    2013-01-01

    To provide rationale for testosterone replacement therapy (TRT) in older men with low testosterone levels and symptoms consistent with testosterone deficiency. The relevant literature was reviewed using PubMed. Cross-sectional and longitudinal population-based studies indicate that total and free testosterone levels fall with aging, and they may be accompanied by symptoms consistent with androgen deficiency. Testosterone treatment of younger men with very low testosterone levels and hypothalamic, pituitary, or testicular disease is associated with improvements in symptoms, body composition, bone density, and hematocrit/hemoglobin. Studies evaluating testosterone treatment of older men with low testosterone levels are limited, but they suggest some increase in fat free mass, some decrease in fat mass, and some increase in bone density of the lumbar spine and femoral neck. The Testosterone Trial should provide definitive information regarding the potential benefits of TRT in men ≥65 years of age. If efficacy is confirmed, we will still need more information regarding the risks of TRT in older men.

  2. Ground reaction forces and kinematics in distance running in older-aged men.

    2003-07-01

    The biomechanics of distance running has not been studied before in older-aged runners but may be different than in younger-aged runners because of musculoskeletal degeneration at older age. This study aimed at determining whether the stance phase kinematics and ground reaction forces in running are different between younger- and older-aged men. Lower-extremity kinematics using three-dimensional motion analysis and ground reaction forces (GRF) using a force plate were assessed in 16 older-aged (55-65 yr) and 13 younger-aged (20-35 yr) well-trained male distance runners running at a self-selected (SRS) and a controlled (CRS) speed of 3.3 m.s-1. The older subjects ran at significantly lower self-selected speeds than the younger subjects (mean 3.34 vs 3.77 m.s-1). In both speed conditions, the older runners exhibited significantly more knee flexion at heel strike and significantly less knee flexion and extension range of motion. No age group differences were present in subtalar joint motion. Impact peak force (1.91 vs 1.70 BW) and maximal initial loading rate (107.5 vs 85.5 BW.s-1) were significantly higher in the older runners at the CRS. Maximal peak vertical and anteroposterior forces and impulses were significantly lower in the older runners at the SRS. The biomechanics of running is different between older- and younger-aged runners on several relevant parameters. The larger impact peak force and initial loading rate indicate a loss of shock-absorbing capacity in the older runners. This may increase their susceptibility to lower-extremity overuse injuries. Moreover, it emphasizes the focus on optimizing cushioning properties in the design and prescription of running shoes and suggests that older-aged runners should be cautious with running under conditions of high impact.

  3. Testosterone Replacement Therapy and Mortality in Older Men.

    Hackett, G I

    2016-02-01

    While US testosterone prescriptions have tripled in the last decade with lower trends in Europe, debate continues over the risks, benefits and appropriate use of testosterone replacement therapy (TRT). Several authors blame advertising and the availability of more convenient formulations, whilst others have pointed out that the routine testing of men with erectile dysfunction (ED) (a significant marker of cardiovascular risk) and those with diabetes would inevitably increase the diagnosis of hypogonadism and lead to an increase in totally appropriate prescribing. They commented that this was merely an appropriate correction of previous under-diagnosis and under-treatment in line with evidence based guidelines. It is unlikely that persuasive advertising or convenient formulations could grow a market over such a sustained period if the treatment was not effective. Urologists and primary care physicians are the most frequent initiators of TRT usually for ED. Benefits are clearly established for sexual function, increase in lean muscle mass and strength, mood and cognitive function, with a possible reduction in frailty and osteoporosis. There remains no evidence that TRT is associated with increased risk of prostate cancer or symptomatic benign prostatic hyperplasia, yet the decision to initiate and continue therapy is often decided by urologists. The cardiovascular issues associated with TRT have been clarified by recent studies showing that therapy associated with clear increases in serum testosterone levels to the normal range is associated with reduced all-cause mortality. Studies reporting to show increased risk have been subject to flawed designs with inadequate baseline diagnosis and follow-up testing. Effectively, they have compared non-treated patients with under-treated or non-compliant subjects involving a range of different therapy regimes. Recent evidence suggests long-acting injections may be associated with decreased cardiovascular risk, but the

  4. Is testosterone treatment dangerous for the cardiovascular system in older hypogonadal men?

    Full Text Available The relationship between testosterone deficiency syndrome (TDS and men's vascular health has a great impact in the modern approach to the aging male. There is good evidence that low testosterone (T is associated with erectile dysfunction (ED and that ED is a strong marker for cardiovascular risk; also, TDS is frequently associated with increased cardiovascular and all-cause mortality. Noteworthy, the occurrence of increased levels of glucose, total cholesterol, low-density lipoprotein, pro-inflammatory cytokines, and myointimal carotid thickness may be associated with reduced T levels especially in cardiac older frail men. Screening for low T should be mandatory in high risk groups including those with type 2 diabetes, metabolic syndrome and obesity. The rising demand from patients to be treated for ED associated with TDS will increase the prescribing of T and facilitate future long-term studies on its impact on cardiovascular disease (CVD. Recent studies suggest warnings with regard to T prescription in older frail men, but we regret that these studies had consistent bias in inclusion criteria and statistical evaluation. Data from studies conducted in more selected populations suggest that T replacement therapy may improve multiple surrogate markers for CVD as well as reducing cardiovascular mortality. After analyzing the most important studies' limitation, we can conclude that at present there is insufficient evidence of a causal relationship between T therapy and adverse cardiovascular outcomes to support against T supplementation in older hypogonadal frail men.

    An augmented pulmonary artery wedge pressure (PAWP) response may explain exercise intolerance in some humans. However, routine use of exercise hemodynamic testing is limited by a lack of data from normal older men and women. Our objective was to evaluate the exercise PAWP response and the potential for sexual dimorphism in healthy, nondyspneic older adults. Thirty-six healthy volunteers (18 men [54 ± 7 yr] and 18 women [58 ± 6 yr]) were studied at rest (control) and during two stages of semi-upright cycle ergometry, at heart rates of 100 bpm (light exercise) and 120 bpm (moderate exercise). Right heart catheterization was performed to measure pulmonary pressures. The PAWP response to exercise was assessed in context of exercise work rate and body size. At control, PAWP was similar between men and women. Work rates were significantly smaller in women at comparable HR (P relative to the increase in cardiac output did not exceed 2 mm Hg·L·min in any volunteer at moderate exercise. The similar rise in the PAWP response to submaximal exercise occurs despite lower work rate in healthy older women compared with men, even when adjusted for smaller body size. It is important to consider sex in the development of normal reference ranges for exercise hemodynamic testing.

    This study investigated the effects of resistance training (RT) on the metabolism of testosterone (T) in younger (n=5, 28±3yrs.) and older (n=8, 70±2yrs.) men. Experimental heavy resistance exercises (5×10RM leg presses) were performed before and after a 12-month of RT. No age differences were found in the production or metabolic clearance rate of T (determined by stable isotope dilution method), skeletal muscle androgen receptor content or serum LH concentrations due to acute or chronic RT. The T production capacity response to gonadotropin stimulation and the concentrations of the urinary T metabolites (androsterone and etiocholanolone) were lower in the older compared to younger men (p<0.05-0.01). This study further showed that RT may have acute effect on T production and clearance rates, while the exercise-induced increases in serum T appeared to be induced by decreased metabolic clearance rate of T. Attenuated T production capacity and urinary excretion of T metabolites in older men may reflect the known reduction in testicular steroidogenesis upon aging. No changes were observed in T metabolism due to RT indicating a homeostatic stability for this hormone in men of different ages.

    The prevalence of frailty increases, whereas testosterone decreases, as men age. Low testosterone may be a risk factor for development of this syndrome. Our objective was to determine whether testosterone levels are associated with frailty. We conducted a prospective cohort study. Between 2001 and 2004, frailty was assessed in 3616 community-dwelling men aged 70-88 yr. Frailty was reassessed in 1586 men aged 76-93 yr in 2008-2009. Frailty was assessed with the FRAIL scale, comprising five domains: fatigue, difficulty climbing a flight of stairs, difficulty walking more than 100 m, more than five illnesses present, or weight loss greater than 5%. Testosterone, SHBG, and LH were assayed at baseline. Free testosterone was calculated using mass action equations. At baseline, 15.2% of men (n = 548) were frail (at least three deficits), increasing to 23.0% (n = 364) at follow-up. At baseline, each 1 sd decrease in total or free testosterone level was associated with increased odds of frailty [odds ratio (OR) = 1.23; 95% confidence interval (CI) = 1.11-1.38, and OR = 1.29; 95% CI = 1.15-1.44 for total and free testosterone, respectively]. Lower LH was associated with reduced odds of frailty (OR = 0.88; 95% CI = 0.81-0.95). Adjustments were made for age, body mass index, smoking, diabetes, social support, and other covariates. At follow-up, only lower free testosterone levels (OR = 1.22; 95% CI = 1.05-1.42) predicted frailty. Lower free testosterone was independently associated with frailty at baseline and follow-up. Randomized trials should explore whether testosterone therapy can prevent the development of frailty.

    An association between increased risk of mortality and disruptions in rest/activity circadian rhythms (RAR) has been shown among adults with dementia and with metastatic colorectal cancer. However, the association among a more general population of older adults has not been studied. Our study population consisted of 2964 men aged > or = 67 yrs of age enrolled in the Outcomes of Sleep Disorders in Older Men (MrOS Sleep) Study. Rest/activity patterns were measured with wrist actigraphy. RAR parameters were computed and expressed as quintiles, and included acrophase (time of peak activity level), amplitude (peak-to-nadir difference), mesor (middle of the peak), pseudo F-value (overall circadian rhythmicity), beta (steepness), and alpha (peak-to-trough width). After adjustment for multiple potential confounders, men in the lowest quintile of pseudo F-value had a 57% higher mortality rate (hazard ratio [HR] = 1.57, 95% CI, 1.03-2.39) than men in the highest quintile. This association was even stronger with increased risk of cardiovascular disease-related mortality (CVD) (HR = 2.32, 95% CI, 1.04-5.22). Additionally, men in the lowest quintile of acrophase had a 2.8-fold higher rate of CVD-related mortality (HR = 2.84, 95% CI, 1.29-6.24). There was no evidence of independent associations with amplitude, mesor, alpha, beta, and mortality risk. Older men with less robust RAR and earlier acrophase timing have modestly higher all-cause and CVD-related mortality rates. Further research should examine potential biological mechanisms underlying this association.

    This study focused on changes in 10-year patterns of alcohol consumption among older women and men, late-life and life history predictors of drinking problems, and gender differences in these predictors. A sample of late-middle-aged community residents (N = 1291) who had consumed alcohol in the past year or shortly before was surveyed at baseline and 1 year, 4 years and 10 years later. At each contact point, participants completed an inventory that assessed their alcohol consumption, drinking problems and health-related and life context factors. Participants also provided information about their life history of drinking. Over the 10 years, the proportion of individuals who consumed alcohol declined. Among individuals who continued to drink, women and men showed comparable declines in alcohol consumption, minor concomitants of alcohol consumption and drinking problems. In addition to the amount of alcohol consumption, smoking, friends' approval of drinking and avoidance coping consistently predicted late-life drinking problems. With respect to life history factors, heavy drinking, drinking problems and increased drinking in response to life events were related to a higher likelihood of late-life drinking problems; obtaining help from family members and friends and, among men, participation in Alcoholics Anonymous, were related to a lower likelihood of problems. Older women and men show comparable declines in alcohol consumption and drinking problems. Specific late-life social context and coping variables, and life history indices, are risk factors for late-life drinking problems among both women and men.

    The decline in testosterone with age has been associated with specific physical changes that affect quality of life and life expectancy, although a cause-and-effect relationship is yet to be established. While female menopause is rapid and well described, "male menopause" or androgen decline in older men is gradual and marked by nonspecific symptoms. This makes diagnosis of true testosterone deficiency and prediction of response to testosterone replacement therapy (TRT) challenging. This article reviews androgen decline in men, focusing on those over age 40, and covers symptoms, indications, contraindications,diagnosis, treatments, and the risks and benefits of treatment [corrected].

    The aging of the human immunodeficiency virus type 1 (HIV-1)-infected population obligates a focus on the interaction between aging, comorbid conditions, and HIV-1. We recruited a cohort of HIV-1-infected men aged ≤ 35 years or ≥ 50 years who were receiving fully suppressive antiretroviral therapy (ART). We analyzed plasma markers of inflammation; T-cell activation, exhaustion, proliferation; and innate cellular subsets and functional capacity. Levels of lipopolysaccharide and the plasma marker of chemokine (C-C motif) ligand 2 were significantly elevated in older HIV-infected men despite comparable cellular phenotypes. Compared with similarly age-stratified uninfected subjects, older HIV-1-infected adults were also more frequently in the upper quartile of soluble CD14 expression.

    Improving physical function and mobility in a continuously expanding elderly population emerges as a high priority of medicine today. Muscle mass, strength/power, and maximal exercise capacity are major determinants of physical function, and all decline with aging. This contributes to the incidence of frailty and disability observed in older men. Furthermore, it facilitates the accumulation of body fat and development of insulin resistance. Muscle adaptation to exercise is strongly influenced by anabolic endocrine hormones and local load-sensitive autocrine/paracrine growth factors. GH, IGF-I, and testosterone (T) are directly involved in muscle adaptation to exercise because they promote muscle protein synthesis, whereas T and locally expressed IGF-I have been reported to activate muscle stem cells. Although exercise programs improve physical function, in the long-term most older men fail to comply. The GH/IGF-I axis and T levels decline markedly with aging, whereas accumulating evidence supports their indispensable role in maintaining physical function integrity. Several studies have reported that the administration of T improves lean body mass and maximal voluntary strength in healthy older men. On the other hand, most studies have shown that administration of GH alone failed to improve muscle strength despite amelioration of the detrimental somatic changes of aging. Both GH and T are anabolic agents that promote muscle protein synthesis and hypertrophy but work through separate mechanisms, and the combined administration of GH and T, albeit in only a few studies, has resulted in greater efficacy than either hormone alone. Although it is clear that this combined approach is effective, this review concludes that further studies are needed to assess the long-term efficacy and safety of combined hormone replacement therapy in older men before the medical rationale of prescribing hormone replacement therapy for combating the sarcopenia of aging can be established

    Full Text Available Abstract Background Data on physical activity in older adults in Germany is scarce. The aim of this study was to analyze physical activity patterns and to explore factors associated with physical activity in different domains, i.e. sporting activities (SA and domestic activities (DA, in older men and women. Methods As part of the 7-year follow-up telephone interviews of the getABI cohort (community-dwelling older adults in Germany, the PRISCUS-PAQ was used to survey participants about their everyday physical activity patterns. Time per week (hh:mm spent in SA and DA (heavy housework, gardening was analyzed for men and women. Multivariate logistic regression analyses were performed in order to assess the odds of participating in SA and DA for at least 2.5 hours/week in association with sociodemographic factors, a broad range of physical health-related factors and interview date (season of the year. Results A total of 1,610 primary health care patients (51.6% women with a median age of 77 (range 72-93 years were included in the analyses. Men engaged in SA more often than women (01:45 vs. 01:10, whereas women did more DA per week than men (04:00 vs. 03:00. Being interviewed in spring or summer was associated with increased performance of DA in both sexes. Participation in these activities was reduced in more highly educated men and women. Living alone increased the odds of sports participation in women, but not in men. Most physical health-related factors were only selectively associated with either SA or DA, in men or women, respectively. The need for a walking aid was the only factor that consistently lowered the odds of being active in both activity domains and sexes. Conclusions This exploratory study delivers reliable and relevant data on the participation in and correlates of sporting and domestic activities of community-dwelling older adults for whom there had previously been only limited information at a population level in Germany

    The present study elucidated the effects of habitual rowing exercise on arterial stiffness and plasma levels of the vasoconstrictor endothelin-1 and the vasodilator nitric oxide (NO) in older men. Eleven rowers (68.0 ± 1.6 years) and 11 sedentary control older men (64.9 ± 1.1 years) were studied. Peak oxygen uptake (36.0 ± 1.7 vs. 27.7 ±1.9 ml · kg(-1) · min(-1)), leg press power (1346 ± 99 vs. 1077 ± 68 W), and HDL-cholesterol (75 ± 5 vs. 58 ±3 mg · ml(-1)) were higher and triglyceride (78 ± 9 vs. 120 ± 14 mg · ml(-1)) was lower in rowers than in control participants (all P cardio-ankle vascular index) and plasma endothelin-1 and NOx (nitrite + nitrate) levels did not differ between the two groups. These results suggest that habitual rowing exercise in older men is associated with high muscle power and aerobic capacity, and favourable blood lipid profile without affecting arterial stiffness or plasma levels of endotheline-1 and NO.

    Full Text Available It has been hypothesized that cellular damage caused by oxidative stress is associated with late-life depression but epidemiological evidence is limited. In the present study we evaluated the association between urinary 8-iso-prostaglandin F2α (8-iso-PGF2α, a biomarker of lipid peroxidation, and depressed mood in a large sample of community-dwelling older adults. Participants were selected from the Health, Aging and Body Composition study, a community-based longitudinal study of older persons (aged 70-79 years. The present analyses was based on a subsample of 1027 men and 948 women free of mobility disability. Urinary concentration of 8-iso-PGF2α was measured by radioimmunoassay methods and adjusted for urinary creatinine. Depressed mood was defined as a score greater than 5 on the 15-item Geriatric Depression Scale and/or use of antidepressant medications. Depressed mood was present in 3.0% of men and 5.5% of women. Depressed men presented higher urinary concentrations of 8-iso-PGF2α than non-depressed men even after adjustment for multiple sociodemographic, lifestyle and health factors (p = 0.03, Cohen's d = 0.30. This association was not present in women (depressed status-by-sex interaction p = 0.04. Our study showed that oxidative damage may be linked to depression in older men from a large sample of the general population. Further studies are needed to explore whether the modulation of oxidative stress may break down the link between late-life depression and its deleterious health consequences.

    Fall-induced injuries in persons aged 65 years and older are a major public health problem. Data regarding circumstances leading to specific injuries, such as traumatic brain injury (TBI) and hip fractures in older adults are scarce. To investigate the activity distributions leading to indoor and outdoor falls requiring an emergency department (ED) visit, and those resulting in TBIs and hip fractures. 5880 older adults who visited the ED due to a fall. Data is descriptive and stratified by age and gender. Two-thirds of all falls occurred indoors. However, there were higher proportions of outdoor falls at ages 65-79 years (48%). Walking up or down stairs (51%) and housekeeping (17%) were the most common indoor activities leading to a TBIs. Walking (42%) and sitting or standing (16%) was the most common indoor activities leading to a hip fracture. The most common outdoor activities were walking (61% for TBIs and 57% for hip fractures) and cycling (10% for TBIs and 24% for hip fractures). In the present study we found that the indoor activities distribution leading to TBIs and hip fractures differed. Notably, about half of the traumatic brain injuries and hip fractures in men and women aged 65-79 years occurred outdoors. This study provides new insights into patterns leading to injurious falls by age, gender and injury type, and may guide the targeting of falls prevention at specific activities and risk groups, including highly functional older men and women.

    Context: Prior studies suggested a role for the arginine vasopressin (AVP) system in the pathogenesis of diabetes. Prospective studies on the association between copeptin (the C-terminal fragment of AVP hormone) and incident diabetes are limited. Objective: We have examined the association between plasma copeptin and the risk of incident diabetes in older men. Design: The British Regional Heart Study was a prospective study with an average of 13 years follow-up. Setting: General practices in the United Kingdom were studied. Participants: Participants were 3226 men aged 60 to 79 years with no prevalent diabetes. Outcome: We measured 253 patients with incident diabetes. Results: Copeptin was positively and significantly associated with renal dysfunction, insulin resistance (homeostasis model assessment of insulin resistance), metabolic risk factors (waist circumference, blood pressure, triglycerides, and liver function), C-reactive protein, tissue plasminogen activator, and von Willebrand factor (endothelial dysfunction) but not with plasma glucose. The risk of incident diabetes was significantly elevated only in men in the top fifth of the copeptin distribution (>6.79 pmol/L), and this risk persisted after adjustment for several diabetes risk factors including metabolic risk factors and C-reactive protein (adjusted hazard ratio in the top fifth vs the rest = 1.78 [95% confidence interval, 1.34–2.37]). Risk was markedly attenuated although it remained significant after further adjustment for homeostasis model assessment of insulin resistance and plasma glucose (adjusted hazard ratio = 1.47 [1.11–1.97]). The increased risk was seen even when the analysis was restricted to men with no chronic kidney disease or to men with no impaired fasting glucose (<6.1 mmol/L). Conclusion: Copeptin is associated with a significantly increased risk of diabetes in older men. The association is partly mediated through lower insulin sensitivity. The findings suggest a potential role

    This study examines different types and sources of social support in relation to psychological distress levels among older Australian gay men. A national community-based survey was conducted involving 242 gay-identified men aged 50 years and older. In univariable regressions, psychological distress was less likely if men were receiving emotional support, practical support, or had a sense of belonging, and also if they had a greater number of close friends and received some or a lot of support from family and gay friends but not from straight friends. Of all these factors, a multivariable regression showed that receiving emotional support was the only significant independent factor. Emotional support appears to play a greater role in the mental health of older gay men than many other types and sources of support. Ensuring access to emotional support may need to be considered when promoting healthier aging among gay men.

    The association between sex hormones and sex hormone binding globin (SHBG) with vertebral fractures in men is not well studied. In these analyses, we determined whether sex hormones and SHBG were associated with greater likelihood of vertebral fractures in a prospective cohort study of community dwelling older men. We included data from participants in MrOS who had been randomly selected for hormone measurement (N=1463, including 1054 with follow-up data 4.6years later). Major outcomes included prevalent vertebral fracture (semi-quantitative grade≥2, N=140, 9.6%) and new or worsening vertebral fracture (change in SQ grade≥1, N=55, 5.2%). Odds ratios per SD decrease in sex hormones and per SD increase in SHBG were estimated with logistic regression adjusted for potentially confounding factors, including age, bone mineral density, and other sex hormones. Higher SHBG was associated with a greater likelihood of prevalent vertebral fractures (OR: 1.38 per SD increase, 95% CI: 1.11, 1.72). Total estradiol analyzed as a continuous variable was not associated with prevalent vertebral fractures (OR per SD decrease: 0.86, 95% CI: 0.68 to 1.10). Men with total estradiol values ≤17pg/ml had a borderline higher likelihood of prevalent fracture than men with higher values (OR: 1.46, 95% CI: 0.99, 2.16). There was no association between total testosterone and prevalent fracture. In longitudinal analyses, SHBG (OR: 1.42 per SD increase, 95% CI: 1.03, 1.95) was associated with new or worsening vertebral fracture, but there was no association with total estradiol or total testosterone. In conclusion, higher SHBG (but not testosterone or estradiol) is an independent risk factor for vertebral fractures in older men.

    Full Text Available Purpose. To examine the associations of optimism and pessimism with all-cause, cardiovascular disease (CVD, coronary heart disease (CHD, and cancer mortality in a population-based sample of older men and women followed ≤12 years. Methods. 367 men and 509 women aged ≥50 from the Rancho Bernardo Study attended a 1999–2002 research clinic visit when demographic, behavioral, and medical history were obtained and completed a 1999 mailed survey including the Life Orientation Test-Revised (LOT-R. Mortality outcomes were followed through 2012. Results. Average age at baseline was 74.1 years; during follow-up (mean = 8.1 years, 198 participants died, 62 from CVD, 22 from CHD, and 49 from cancer. Total LOT-R, optimism and pessimism scores were calculated. Participants with the highest optimism were younger and reported less alcohol use and smoking and more exercise. Cox proportional hazard models showed that higher total LOT-R and optimism, but not pessimism scores, were associated with reduced odds of CHD mortality after adjusting for age, sex, alcohol, smoking, obesity, physical exercise, and medication (HR = 0.86, 95% CI = 0.75, 0.99; HR = 0.77, 95% CI = 0.61, 0.99, resp.. No associations were found for all-cause, CVD, or cancer mortality. Conclusions. Optimism was associated with reduced CHD mortality in older men and women. The association of positive attitudes with mortality merits further study.

    Older HIV-infected gay men may experience multiple forms of stigma related to sexual orientation (homonegativity), HIV (HIV stigma), and age (ageism), all of which can negatively impact quality of life (QOL). Our purpose was to determine predictors of homonegativity, internalized HIV stigma, and ageism, and stigma experiences that were predictive of QOL. Sixty HIV-infected gay men, ages 50-65 years, participated. Younger age and emotion-focused coping were significantly predictive of homonegativity, accounting for 28% of variance. Younger age, support group participation, medications per day, social support, and emotion-focused coping predicted internalized HIV stigma, accounting for 35% of variance. Problem-focused coping predicted ageism, accounting for 7% of variance. In regression analysis, the three types of stigma accounted for 39% of variance in QOL (homonegativity 19%, internalized HIV stigma 19%, ageism 0.5%). Study findings may help researchers develop interventions to alleviate multiple stigma experiences of HIV-infected older gay men, thus improving QOL.

    The purpose of this study was to determine the potential relationship between muscle power of the lower extremities and the physical activity in older men with chronic obstructive pulmonary disease (COPD). Forty-four men (70.3 ± 6.7 years old) with moderate-to-severe COPD completed the 6-min walk test (6MWT), BODE (body mass index, obstruction, dyspnea, and exercise), a one-repetition maximum strength of the quadriceps femoris (1RMQF), and muscle power at 50% and 70% 1RMQF. Physical activity was measured using an accelerometer. The 6MWT was associated with muscle power at 50% 1RMQF (r = .40; P = .013) but not muscle power at 70% 1RMQF (r = .24; P = .15) or 1RMQF (r = .13; P = .44). Light-intensity activity was positively correlated with muscle power at 50% 1RMQF (r = .52; P = .001). Lower limb muscle power is associated with the 6MWT and light-intensity activities in older men with COPD.

This research article examines health literacy and health-seeking behaviors among elderly men in Jamaica, in order to inform health policy. This is a descriptive cross-sectional study. A 133-item questionnaire was administered to a random sample of 2,000 men, 55 years and older, in St Catherine, Jamaica. In this study, 56.9% of urban and 44.5% of rural residents were health literate. Only 34.0% of participants purchased medications prescribed by the medical doctor and 19.8% were currently smoking. Despite the reported good self-related health status (74.4% and high cognitive functionality (94.1% of the older men, only 7.9% sought medical care outside of experiencing illnesses. Thirty-seven percent of rural participants sought medical care when they were ill compared with 31.9% of their urban counterparts. Thirty-four percent of the participants took the medication as prescribed by the medical doctor; 43% self-reported being diagnosed with cancers such as prostate and colorectal in the last 6 months, 9.6% with hypertension, 5.3% with heart disease, 5.3% with benign prostatic hyperplasia, 5.3% with diabetes mellitus, and 3.8% with kidney/bladder problems. Approximately 14% and 24% of the participants indicated that they were unaware of the signs and symptoms of hypertension

    Racial/ethnic minorities tend to underutilize hospice services. Guided by Andersen behavioral health model, the purpose of this study was to explore the predictors of the willingness to use hospice services in racially/ethnically diverse older men and women. Data were drawn from the Survey of Older Floridians: 504 non-Hispanic whites, 360 African Americans, 328 Cuban Americans, and 241 non-Cuban Hispanics. In each group, logistic regression models of the willingness to use hospice were estimated. A greater likelihood of willingness was observed among younger non-Hispanic whites and among African Americans with fewer functional disabilities. In non-Cuban Hispanics, English proficiency increased the willingness by 3.1 times. Findings of the study identified group-specific factors contributing to the willingness to use hospice services and hold implications for tailored intervention programs. © The Author(s) 2015.

    Full Text Available The aim of this study was to examine the effects of resistance training on hematological blood markers in older individuals. Twenty-nine men and women participated to this study. Subjects were randomized in 2 groups: (1 control (n=13 and (2 resistance training (n=16. At baseline and after the intervention, subjects were submitted to a blood sample to determine their hematological profile (red blood cells, hemoglobin, hematocrit, platelets, leukocytes, neutrophils, lymphocytes, monocytes, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, red cell distribution width. At baseline, no difference was observed between groups. Moreover, we found no significant difference after the intervention on any of these markers. A 6-month resistance program in healthy older individuals seems to have no beneficial nor deleterious effects on hematological blood parameters. However, resistance training was well tolerated and should be recommended for other health purposes. Further studies are needed to confirm these results in a large population.

    We compared the walking economy in older participants with and without type 2 diabetes. Walking economy was determined in 115 older participants with type 2 diabetes and 130 older control participants without diabetes by continuously measuring oxygen uptake during a treadmill test in which the work rate was at a constant speed of 2 mph and a grade of 0% for a duration of 10 minutes. Participants also completed a Balke treadmill protocol for the determination of peak oxygen uptake, defined as the highest oxygen uptake value attained during the final work stage attained. Fractional utilization was then calculated as the walking economy oxygen uptake divided by peak oxygen uptake, expressed as a percentage. Compared to those without diabetes, participants with type 2 diabetes were older (p=0.042), had higher prevalence of men (p=0.034), obesity (p=0.010), chronic kidney disease (p=0.020), peripheral artery disease (p=0.024), and had a higher body mass index (p=0.025), and waist/hip ratio (p=0.006). After adjusting for these variables, the participants with diabetes had higher walking economy (peconomy in the diabetic participants is further magnified by their lower aerobic fitness, thereby leading to a higher fractional utilization of oxygen consumed during a given walking task.

    This study compared the intensity and energy cost of playing 9 holes of golf with 40 min of lawn mowing in older men and determined whether both met the current recommendations for health benefits. Eighteen men (age 71.2 +/- 4.4 yr, BMI 27.3 +/- 2.3; M +/- SD) completed a graded treadmill test. During golfing and lawn-mowing field tests, oxygen consumption and walking velocity and distance were measured using a portable metabolic system and global positioning system receiver. The net energy costs of golfing and lawn mowing were 310 and 246 kcal, respectively. The average intensities in metabolic equivalents of golfing and lawn mowing were 2.8 +/- 0.5 and 5.5 +/- 0.9, respectively. Both lawn mowing and golfing met the original intensity and energy expenditure requirements for health benefits specified by the American College of Sports Medicine in 1998, but only lawn mowing met the 2007 intensity recommendations.

    Background Antihypertensive drugs are prescribed commonly in older adults for their beneficial cardiovascular and cerebrovascular effects, but few studies have assessed antihypertensive drugs’ adverse effects on non-cardiovascular outcomes in routine clinical practice. Objective To evaluate, among older adults, the association between antihypertensive medication use and physical performance, cognition, and mood. Design and Setting Prospective cohort study in a Veterans Affairs primary care clinic, with patients enrolled in 2000–2001 and assessed for medication use, comorbidities, health behaviors, and other characteristics; and followed-up 1 year later. Participants 544 community-dwelling hypertensive men over age 65 years. Measurements Timed chair stands; Trail Making Test part B; and Centers for Epidemiologic Studies Depression (CES-D) scores. Results Participants had a mean age of 74.4 ± 5.2 years and took a mean of 2.3 ± 1.2 antihypertensive medications at baseline. After adjustment for age, comorbidities, level of blood pressure, and other confounders, each 1-unit increase in antihypertensive medication “intensity” was associated with a 0.11-second (95% confidence interval, 0.05–0.16) increase in the time required to complete the timed chair stands. No significant relationship was found between antihypertensive medication intensity and outcomes for Trail Making B or CES-D scores. Conclusions A higher cumulative exposure to antihypertensive medications in community-living older men was associated with adverse effects on physical performance, but not on the cognitive or depression measures available in this study. Clinicians should consider non-cardiovascular related adverse effects when treating older males taking multiple antihypertensive medications. PMID:17899299

    There is evidence showing an important role of estrogens in men's health. We aimed to evaluate whether estradiol levels are associated with overall mortality and specific fatal events.We measured estradiol levels in 2,078 men who were routinely referred for coronary angiography (1997-2000).The main outcome measures were Cox proportional hazard ratios (HRs) for mortality from all causes, from cardiovascular and non-cardiovascular causes including cancer according to estradiol levels.Multivariable HRs (with 95% confidence intervals) for all-cause, non-cardiovascular, and cancer mortality were 1.43 (1.08-1.91), 2.11 (1.34-3.34), and 2.27 (1.00-5.19), respectively, in the fourth estradiol quartile as compared to the first. There was no significant association of estradiol levels with cardiovascular mortality. In multivariate adjusted analyses, higher estradiol levels in men were significantly associated with prevalent strokes, peripheral vascular disease, and carotid artery stenosis compared to lower estradiol levels.High levels of estradiol are associated with all-cause and non-cardiovascular mortality in a large cohort of older men referred to coronary angiography. Further studies are warranted to confirm our results and to elucidate the underlying mechanisms. Georg Thieme Verlag KG Stuttgart · New York.

  14. Quantitative and theoretical analyses of the relation between older brothers and homosexuality in men.

    2004-09-21

    Meta-analysis of aggregate data from 14 samples representing 10,143 male subjects shows that homosexuality in human males is predicted by higher numbers of older brothers, but not by higher numbers of older sisters, younger brothers, or younger sisters. The relation between number of older brothers and sexual orientation holds only for males. This phenomenon has therefore been called the fraternal birth order effect. Research on birth order, birth weight, and sexual orientation suggests that the developmental pathway to homosexuality initiated by older brothers operates during prenatal life. Calculations assuming a causal relation between older brothers and sexual orientation have estimated the proportion of homosexual men who owe their sexual orientation to fraternal birth order at 15% in one study and 29% in another. The maternal immune hypothesis proposes that the fraternal birth order effect reflects the progressive immunization of some mothers to male-specific antigens by each succeeding male fetus and the increasing effects of such immunization on sexual differentiation of the brain in each succeeding male fetus. There are at least three possible mechanisms by which the mother's immune response could influence the fetus: the transfer of anti-male antibodies across the placenta from the maternal into the fetal compartment, the transfer of maternal cytokines across the placenta, and maternal immune reactions affecting the placenta itself. This hypothesis is consistent with recent studies showing that the quantity of fetal cells that enter the maternal circulation is greater than previously thought, and that the number of male-specific proteins encoded by Y-chromosome genes is greater than previously thought.

    IMPORTANCE Recent studies have yielded conflicting results as to whether testosterone treatment increases cardiovascular risk. OBJECTIVE To test the hypothesis that testosterone treatment of older men with low testosterone slows progression of noncalcified coronary artery plaque volume. DESIGN, SETTING, AND PARTICIPANTS Double-blinded, placebo-controlled trial at 9 academic medical centers in the United States. The participants were 170 of 788 men aged 65 years or older with an average of 2 serum testosterone levels lower than 275 ng/dL (82 men assigned to placebo, 88 to testosterone) and symptoms suggestive of hypogonadism who were enrolled in the Testosterone Trials between June 24, 2010, and June 9, 2014. INTERVENTION Testosterone gel, with the dose adjusted to maintain the testosterone level in the normal range for young men, or placebo gel for 12 months. MAIN OUTCOMES AND MEASURES The primary outcome was non calcified coronary artery plaque volume, as determined by coronary computed tomographic angiography. Secondary outcomes included total coronary artery plaque volume and coronary artery calcium score (range of 0 to >400 Agatston units, with higher values indicating more severe atherosclerosis). RESULTS Of 170 men who were enrolled, 138 (73 receiving testosterone treatment and 65 receiving placebo) completed the study and were available for the primary analysis. Among the 138 men, the mean (SD) age was 71.2 (5.7) years, and 81%were white. At baseline, 70 men (50.7%) had a coronary artery calcification score higher than 300 Agatston units, reflecting severe atherosclerosis. For the primary outcome, testosterone treatment compared with placebo was associated with a significantly greater increase in noncalcified plaque volume from baseline to 12 months (from median values of 204 mm3 to 232 mm3 vs 317 mm3 to 325 mm3, respectively; estimated difference, 41 mm3; 95%CI, 14 to 67 mm3; P = .003). For the secondary outcomes, the median total plaque volume increased

    Thyroid hormones regulate cellular survival and metabolism; however, their association with cancer incidence and death has not been well explored. Our aim was to examine the relationship between thyrotropin (TSH) and free thyroxine (FT4) with cancer incidence (all cancers, prostate, colorectal and lung cancer). Associations with cancer-related deaths were also explored. A prospective cohort study involving community-dwelling men aged 70-89 years. Thyroid hormones were measured in 3836 men between 2001 and 2004. Competing risks analyses were used to perform longitudinal analyses with results expressed as subhazard ratios (SHR). Outcomes were ascertained through electronic linkage until 20 June 2013. Mean age was 77·0 ± 3·6 years. A total of 864 men developed cancers, and 506 experienced cancer-related deaths. A total of 340, 136 and 119 men developed prostate, colorectal and lung cancers, respectively. After adjustments, there were no associations between TSH and incidence of all cancers, prostate or lung cancer. Higher TSH was associated with increased colorectal cancer incidence (SHR = 1·19, 95% CI 1·00-1·42; P = 0·048 for every 1 SD increase in log TSH). This association was strengthened after excluding the first year of follow-up (SHR = 1·23, 95% CI 1·02-1·48, P = 0·028). FT4 was not associated with incidence of all cancers, prostate, colorectal or lung cancer. Thyroid hormones were not associated with cancer-related deaths. In community-dwelling older men, FT4 was not associated with cancer incidence. Higher TSH is independently associated with increased incidence of colorectal cancer. Further investigation is warranted to determine whether a causal relationship exists. © 2016 John Wiley & Sons Ltd.

    We examine the associations between different patterns of sexual behavior and function and three indicators of subjective well-being (SWB) covering eudemonic, evaluative, and affective well-being in a representative sample of partnered older people. Using data from a Sexual Relationships and Activities Questionnaire (SRA-Q) in Wave 6 of the English Longitudinal Study of Ageing, latent class analysis identified groups characterized by distinctive patterns of sexual behavior and function and then examined their link to SWB. Eudemonic SWB was measured using a revised 15-item version of the CASP-19, evaluative SWB using the Satisfaction With Life Scale, and affective SWB using the 8-item version of the Centre for Epidemiologic Studies-Depression scale. Sexual behavior and function was best described by six classes among men and five classes among women. These ranged from high sexual desire, frequent partnered sexual activities, and few sexual problems (Class 1) to low sexual desire, infrequent/no sexual activity, and problems with sexual function (Class 5([women])/6([men])). Men and women who reported either infrequent/no sexual activity, or were sexually active but reported sexual problems, generally had lower SWB than those individuals identified in Class 1. Poorer SWB in men was more strongly associated with sexual function difficulties, whereas in women desire and frequency of partnered activities appeared more important in relation to SWB. Within the context of a partnered relationship continuing sexual desire, activity and functioning are associated with higher SWB, with distinctive patterns for women and men. © The Author 2016.

    Full Text Available Examination of predictors of late-life cognitive functioning is particularly salient in at-risk older adults, such as those who have been recently hospitalized. Sleep and inflammation are independently related to late-life cognitive functioning. The potential role of sleep as a moderator of the relationship between inflammation and global cognitive functioning has not been adequately addressed. We examined the relationship between self-reported sleep duration, inflammatory markers, and general cognitive functioning in hospitalized older men. Older men (n=135; Mean age=72.9 ± 9.7 years were recruited from inpatient rehabilitation units at a VA Medical Center to participate in a cross-sectional study of sleep. Participants completed the Mini-Mental State Examination and Pittsburgh Sleep Quality Index, and underwent an 8am blood draw to measure inflammatory markers [i.e., C-reactive protein (CRP, tumor necrosis factor alpha (TNFα, soluble intercellular adhesion molecule-1 (sICAM-1, and interleukin-6 (IL-6]. Hierarchical regression analyses (controlling for age, education, race, depression, pain, health comorbidity, and BMI revealed that higher levels of CRP and sICAM are associated with higher global cognitive functioning in older men with sleep duration ≥6 hours (β=-0.19, β=-0.18, p’s.05. In elderly hospitalized men, sleep duration moderates the association between inflammation and cognitive functioning. These findings have implications for the clinical care of older men within medical settings.

    AMP-activated protein kinase (AMPK) is a key energy-sensitive enzyme that controls numerous metabolic and cellular processes. Mammalian target of rapamycin (mTOR) is another energy/nutrient-sensitive kinase that controls protein synthesis and cell growth. In this study we determined whether older versus younger men have alterations in the AMPK and mTOR pathways in skeletal muscle, and examined the effect of a long term resistance type exercise training program on these signaling intermediaries. Older men had decreased AMPKα2 activity and lower phosphorylation of AMPK and its downstream signaling substrate acetyl-CoA carboxylase (ACC). mTOR phosphylation also was reduced in muscle from older men. Exercise training increased AMPKα1 activity in older men, however, AMPKα2 activity, and the phosphorylation of AMPK, ACC and mTOR, were not affected. In conclusion, older men have alterations in the AMPK-ACC and mTOR pathways in muscle. In addition, prolonged resistance type exercise training induces an isoform-selective up regulation of AMPK activity. PMID:23000302

    Full Text Available BACKGROUND: There is a lack of evidence on the contribution of mild cognitive impairment (MCI to institutionalization in older adults. This study aimed to evaluate a range of risk factors including MCI of institutionalization in older men. METHODS: Men aged ≥70 years (n = 1705, participating in the Concord Health and Ageing in Men Project, Sydney, Australia were studied. Participants completed self-reported questionnaires and underwent comprehensive clinical assessments during 2005-2007. Institutionalization was defined as entry into a nursing home facility or hostel at any time over an average of 5 years of follow-up. Cox regression analysis was conducted to generate hazard ratios (HR with 95% confidence intervals (CI. RESULTS: A total of 125 (7.3% participants were institutionalized. Piecewise Cox proportional models were generated and divided at 3.4 years (1250 days of follow-up due to violation of the proportional hazards assumption for the association between MCI and institutionalization (χ(2 = 6.44, p = 0.01. Dementia, disability in Activities of Daily Living (ADL and Instrumental Activities of Daily Living (IADL, poor grip strength, few social interactions, being a Non-English speaking immigrant and age were predictive of institutionalization during both time periods, whereas MCI (HR = 4.39, 95%CI 2.17-8.87 only predicted institutionalization in the period beyond 3.4 years of follow-up. Being married (HR = 0.42, 95%CI: 0.24-0.72 was protective only during the period after 3.4 years of follow-up. DISCUSSION: In this study, the strongest predictors of institutionalization were dementia, MCI, ADL and IADL disability. MCI was not a predictor of early institutionalization but became a significant predictor beyond 3.4 years of follow-up.

    The aim of this cross-sectional study was to concurrently assess musculo-articular stiffness (MAS) and muscle stiffness (MS) of the knee extensors in younger and older individuals. Fourteen young (22.1 ± 3.0 years old) and 12 older (65.4 ± 5.7 years old) men were tested for maximal voluntary contraction (MVC), rate of torque development (RTD), muscle thickness, MAS, and MS of knee extensors. MVC, RTD, and muscle thickness were higher in the younger group (288.6 vs. 194.3 Nm, 1319.5 vs. 787.0 Nm s(-1), 23.1 vs. 17.7 mm, respectively, P < 0.05). MAS normalized to the load supported (30% of MVC) was not different between groups (87.9 vs. 88.5 Nm(-1) kg(-1)), whereas the older group exhibited a higher level of normalized MS (23.2 vs. 18.6 Nm(-1) kg(-1), P < 0.05). Determinants of MS have been highlighted along with their role in elevated MS. The unaltered level of MAS, which is functionally important in an aging population, might be achieved through a decrease in tendon stiffness. Copyright © 2012 Wiley Periodicals, Inc.

    The aim of this study was to determine how rated appetite relates to the amount eaten in a meal in healthy older people. On two study days, 32 healthy older men (n = 16) and women (n = 16) aged 65-85 years, recruited by advertisement, consumed a standardised breakfast and 4 h later were offered lunch from which they could eat freely. Foods eaten at lunch were weighed and energy intake calculated from nutrient composition data. Appetite was assessed at baseline and at 30-min intervals between meals by line ratings of hunger, fullness, nausea and how much could be eaten. The optimum time for correlations both among appetite ratings and between appetite and lunch intake was just before the lunch. Mean coefficients of repeatability (21-38 mm) and correlation coefficients (0.67-0.71) at that point in time were similar to those reported previously in young adults. Thus, in older and well as young adults, the size of a meal is most closely related to rated appetite just before the meal.

    Previous research shows that older men tend to have lower nutritional intakes and higher risk of under-nutrition compared with younger men. The objectives of this study were to describe energy and nutrient intakes, assess nutritional risk and investigate factors associated with poor intake of energy and key nutrients in community-dwelling men aged ≥75 years participating in the Concord Health and Ageing in Men Project - a longitudinal cohort study on older men in Sydney, Australia. A total of 794 men (mean age 81·4 years) had a detailed diet history interview, which was carried out by a dietitian. Dietary adequacy was assessed by comparing median intakes with nutrient reference values (NRV): estimated average requirement, adequate intake or upper level of intake. Attainment of NRV of total energy and key nutrients in older age (protein, Fe, Zn, riboflavin, Ca and vitamin D) was incorporated into a 'key nutrients' variable dichotomised as 'good' (≥5) or 'poor' (≤4). Using logistic regression modelling, we examined associations between key nutrients with factors known to affect food intake. Median energy intake was 8728 kJ (P5=5762 kJ, P95=12 303 kJ), and mean BMI was 27·7 (sd 4·0) kg/m2. Men met their NRV for most nutrients. However, only 1 % of men met their NRV for vitamin D, only 19 % for Ca, only 30 % for K and only 33 % for dietary fibre. Multivariate logistic regression analysis showed that only country of birth was significantly associated with poor nutritional intake. Dietary intakes were adequate for most nutrients; however, only half of the participants met the NRV of ≥5 key nutrients.

    East and South Asian male immigrants show markedly low odds of prostate cancer screening as compared to U.S.-born men. However, knowledge about these immigrants' culture-based screening behavior and barriers to screening is extremely limited. This study investigates factors influencing receipt of prostate cancer screening among Korean American immigrant men, particularly investigating culture's impact on screening behaviors. Data were collected through a convenience and purposive sampling technique from 134 Korean American males aged 50 and older recruited in New York City. A structured questionnaire was used and cultural variables were measured by adopting items from Tang and colleagues' work. Approximately 60 % of the sample had received a prostate-specific antigen (PSA) test in their lifetime, and of these, about 66 % reported having done so in the previous 12 months. Logistic regression analysis revealed that a crisis-oriented intervention approach was associated with a substantially reduced likelihood of screening. A positive correlation was noted between the use of Eastern medicine and PSA test receipt. Further analysis revealed a significant interaction effect between use of Eastern medicine and age in predicting PSA test uptake. Culture-specific intervention strategies for increasing prostate cancer screening in this group are discussed, with particular attention to increasing pertinent health literacy. Health professionals should consider the cultural domain when working with Korean immigrant men in order to provide culturally competent care.

    Full Text Available Purpose. To evaluate the cost-effectiveness of denosumab versus other osteoporotic treatments in older men with osteoporosis from a US payer perspective. Methods. A lifetime cohort Markov model previously developed for postmenopausal osteoporosis (PMO was used. Men in the model were 78 years old, with a BMD T-score of −2.12 and a vertebral fracture prevalence of 23%. During each 6-month Markov cycle, patients could have experienced a hip, vertebral or nonhip, nonvertebral (NHNV osteoporotic fracture, remained in a nonfracture state, remained in a postfracture state, or died. Background fracture risks, mortality rates, persistence rates, health utilities, and medical and drug costs were derived from published sources. Previous PMO studies were used for drug efficacy in reducing fracture risk. Lifetime expected costs and quality-adjusted life-years (QALYs were estimated for denosumab, generic alendronate, risedronate, ibandronate, teriparatide, and zoledronate. Results. Denosumab had an incremental cost-effectiveness ratio (ICER of $16,888 compared to generic alendronate and dominated all other treatments. Results were most sensitive to changes in costs of denosumab and the relative risk of hip fracture. Conclusion. Despite a higher annual treatment cost compared to other medications, denosumab is cost-effective compared to other osteoporotic treatments in older osteoporotic US men.

    According to mathematical modeling, HIV is more likely to spread through a population of men who have sex with men when high numbers practice versatile anal sex roles, that is, engage in both insertive (IAI) and receptive anal intercourse (RAI). Yet, actual patterns of versatility remain largely unknown, particularly among older men who currently face growing rates of HIV. In this study, 1,135 Australian gay men aged 40 years and older completed a national online survey of their sexual health and behavior over the past 12 months. Of men who had anal intercourse, 62 % engaged in both IAI and RAI. Factors associated with being versatile included younger age (P = 0.01), higher income (P = 0.009), and larger numbers of sexual partners (P = 0.003). Among men with multiple sexual partners, 20 % were highly versatile, that is, reported similar numbers of IAI and RAI partners. Having HIV (P = 0.003) and living in a rural area (P = 0.04) were significantly associated with being highly versatile. These data point to high rates of versatility among older Australian gay men, with implications for mathematical predictions of change in HIV epidemics and for the design of future HIV prevention strategies.

    Risk for suicide is elevated among older men. We examined whether value placed on autonomy amplifies the relation between depressive symptoms and suicide risk differently for older men and women. Participants were 98 community-dwelling older adults, M age 73.6 (SD = 8.6), 65.1% female, 93.1% White. Questionnaires measured suicide risk (SBQ-R), depressive symptoms (CESD), and value placed on autonomy (PSI-II autonomy). Among men, depressive symptoms were associated with suicide risk only when PSI-II autonomy was elevated. Among women, greater depressive symptoms were associated with suicide risk at all levels of PSI-II autonomy. Further research on attitudes toward autonomy is warranted.

    Compared with young adults, older adults have significantly impaired capacities to resist oxidative damage when faced with acute stress such as ischemia/reperfusion. This impairment likely contributes to increased morbidity and mortality in older adults in response to acute trauma, infections, and the susceptibility to diseases such as atherosclerosis, cancer, diabetes, and Alzheimer's disease. Consumption of foods high in polyphenols, particularly anthocyanins, have been associated with improved health, but the mechanisms contributing to these salutary effects remain to be fully established. This study tested the hypothesis that consumption of tart cherry juice containing high levels of anthocyanins improves the capacity of older adults to resist oxidative damage during acute oxidative stress. In a double-blind, placebo-controlled, crossover design, 12 volunteers [6 men and 6 women; age 69 ± 4 y (61–75 y)] consumed in random order either tart cherry juice or placebo (240 mL twice daily for 14 d) separated by a 4-wk washout period. The capacity to resist oxidative damage was measured as the changes in plasma F2-isoprostane levels in response to forearm ischemia-reperfusion (I/R) before and after each treatment. The tart cherry juice intervention reduced the I/R-induced F2-isoprostane response (P < 0.05), whereas placebo had no significant effect. The tart cherry juice intervention also reduced basal urinary excretion of oxidized nucleic acids (8-hydroxy-2′-deoxyguanosine, 8-hydroxyguanosine) (P < 0.05) but not urinary excretion of isoprostanes. These data suggest that consumption of tart cherry juice improves antioxidant defenses in vivo in older adults as shown by an increased capacity to constrain an oxidative challenge and reduced oxidative damage to nucleic acids.

    Physical activity is recommended for older adults, including those with knee pathology. However, demands on the knee during popular recreational activities are unclear. The study purpose was to determine knee biomechanics in healthy older men during golf and bowling and compare them to activities of daily living. Three-dimensional motion analysis was used to determine knee biomechanics in 19 healthy males (45-73 years): 11 golfers and eight bowlers. Subjects performed walking, stair ascent, stair descent, and either golf or bowling. Comparisons were made between the recreational activity and activities of daily living. During bowling, flexion angle at peak extensor moment was as high as during stair descent, and peak extensor moment was as high as during stair ascent. For the golf lead knee, flexion angle at peak extensor moment and peak extensor moment were as high as during stair ascent, and peak abduction moment, internal and external rotation angles were larger than during all activities of daily living. Peak external rotation angle for the golf trail knee was larger than all activities of daily living. The greatest challenge for the knee of healthy older males during bowling is eccentric control of knee flexion. Golf poses challenges in all three planes of motion for the lead knee and in the transverse plane for the trail knee. Comparing mechanical demands on the knee during bowling and golf to those of stair negotiation provides a reference for clinicians when recommending recreational activities for older adults with knee pathology.

    Men who have sex with men (MSM) continue to be disproportionately affected by HIV in the US. HIV among older adults also continues to be an important public health problem. Age is associated with disclosure of HIV serostatus and self-efficacy for condom use. However, studies examining self-efficacy and disclosure among older MSM (age 50 and older) living with HIV are lacking. The aim of this study was to assess the associations between being 50 and older, and disclosure behaviors, intentions and attitudes, and self-efficacy for condom use, disclosure, and negotiation for safer sex practices among HIV-positive MSM. Data were gathered from 340 participants at the baseline assessment of a longitudinal disclosure intervention study. Linear regression was used to determine the association between being older (age 50 and older) and disclosure behaviors, intentions and attitudes, and self-efficacy for condom use, disclosure, and negotiation for safer sex practices. After adjusting for time since diagnosis and number of sexual partners, MSM aged 50 and older scored lower in disclosure behavior (β = -7.49; 95% CI: -14.8, -0.18) and in self-efficacy for negotiation of safer sex practices (β = -0.80; 95% CI: -1.57, -0.04) compared to MSM 18-34 years. Intervention and prevention programs should endeavor to improve disclosure and self-efficacy for negotiating safer sex practices among older HIV-positive MSM. More health care providers should initiate sexual health discussions, especially among older HIV-positive MSM populations, which may help to improve their disclosure behavior and self-efficacy for negotiating safer sex practices.

    Objective Previous studies of handedness and cognitive function rely on self-classification and yield inconsistent results. This study examines the associations of self-reported versus grip-strength-based handedness with cognitive function in healthy older men and women. Design Cross-sectional study. Setting 1988–91 follow-up clinic visit and 1991 mailed survey. Participants 684 men and 985 women aged 55–95 who were community dwelling. Measurements Cognitive function was assessed with 12 tests and grip strength was measured by hand-held dynamometer. Self-reported handedness was obtained with a mailed survey. Results By self-report, 92.1% of men and women were right-handed; 2.0% were left handed. By grip strength, in men, 64.3% were right-handed, 22.5% left-handed, and 13.2% ambidextrous. In women, 61.3% were right-handed, 17.3% left-handed, and 21.4% ambidextrous. No cognitive function differences were found by self-reported handedness in either sex (p’s>0.10). However, based on grip strength, left-handed women scored poorer than right-handed or ambidextrous women in immediate and delayed memory, attention, and verbal fluency (p’sambidextrous individuals based on grip strength were more likely to show poor cognitive function on 4 of 5 tests. Conclusion Grip strength is a useful alternative to self-reports for classifying handedness. Left-handedness by grip-strength, may be related to poorer cognitive function; this association may vary by gender. PMID:18953462

    Protein-rich supplements are used widely for the management of malnutrition in young and older people. Protein is the most satiating of the macronutrients in young. It is not known how the effects of oral protein ingestion on energy intake, appetite, and gastric emptying are modified by age. The aim of the study was to determine the suppression of energy intake by protein compared with control and underlying gastric-emptying and appetite responses of oral whey protein drinks in eight healthy older men (69-80 yr) compared with eight young male controls (18-34 yr). Subjects were studied on three occasions to determine the effects of protein loads of 30 g/120 kcal and 70 g/280 kcal compared with a flavored water control-drink (0 g whey protein) on energy intake (ad libitum buffet-style meal), and gastric emptying (three-dimensional-ultrasonography) and appetite (0-180 min) in a randomized, double-blind, cross-over design. Energy intake was suppressed by the protein compared with control (P = 0.034). Suppression of energy intake by protein was less in older men (1 ± 5%) than in young controls (15 ± 2%; P = 0.008). Cumulative energy intake (meal+drink) on the protein drink days compared with the control day increased more in older (18 ± 6%) men than young (1 ± 3%) controls (P = 0.008). Gastric emptying of all three drinks was slower in older men (50% gastric-emptying time: 68 ± 5 min) than young controls (36 ± 5 min; P = 0.007). Appetite decreased in young, while it increased in older (P protein-induced suppression of energy intake by whey protein compared with young controls, so that in the elderly men, protein ingestion increased overall energy intake more than in the young men.

    In this article we describe the connections between prostate cancer support groups (PCSGs) and men's health literacy and consumer orientation to health care services. The study findings are drawn from participant observations conducted at 16 PCSGs in British Columbia, Canada and 54 individual interviews that focused on men's experiences of attending group meetings. Men's communication and interactions at PCSGs provide important insights for how men talk about and conceptualize health and illness. For example, biomedical language often predominated at group meetings, and men used numbers and measures to engage with risk discourses in linking prostate cancer markers to various treatment options and morbidity and mortality rates. Many groups afforded opportunities for men to interact with health care providers as a means to better understand the language and logic of prostate cancer management. The health literacy skills fostered at PCSGs along with specific group-informed strategies could be mobilized in the men's subsequent clinical consultations. Consumer discourses and strategies to contest power relations with health care professionals underpinned many men's search for prostate cancer information and their commitment to assisting other men. Key were patients' rights, and perhaps responsibility, to compare diverse health products and services in making decisions across the entire trajectory of their prostate cancer. Overall, the study findings reveal PCSGs as having the capacity to contest as well as align with medical expertise and services facilitating men's transition from patient to informed health care consumers. The processes through which this occurs may direct the design of older men's health promotion programs.

    It remains unknown if inactivity changes the mechanical properties of the human patellar tendon in younger and older healthy persons. The purpose was to examine the effects of short-term unilateral immobilization on the structural and mechanical properties of the patellar tendon in older men and younger men, in vivo. Eight older men and eight younger men underwent 14 days of unilateral immobilization. All individuals were assessed on both sides before and after the intervention. MRI was used to assess whole patellar tendon dimensions. The mechanical properties of the patellar tendon were assessed using simultaneous force and ultrasonographic measurements during isometric ramp contractions.

    Full Text Available BACKGROUND: In many communities, older men (i.e., over 25 years of age have not come forward for Voluntary Medical Male Circumcision (VMMC services. Reasons for low demand among this group of men are not well understood, and may vary across geographic and cultural contexts. This paper examines the facilitators and barriers to VMMC demand in Turkana County, Kenya, with a focus on older men. This is one of the regions targeted by the VMMC program in Kenya because the Turkana ethnic group does not traditionally circumcise, and the rates of HIV and STD transmission are high. METHODS AND FINDINGS: Twenty focus group discussions and 69 in-depth interviews were conducted with circumcised and uncircumcised men and their partners to elicit their attitudes and perceptions toward male circumcision. The interviews were conducted in urban, peri-urban, and rural communities across Turkana. Our results show that barriers to circumcision include stigma associated with VMMC, the perception of low risk for HIV for older men and their "protection by marriage," cultural norms, and a lack of health infrastructure. Facilitators include stigma against not being circumcised (since circumcision is associated with modernity, protection against disease including HIV, and cleanliness. It was also noted that older men should adopt the practice to serve as role models to younger men. CONCLUSIONS: Both men and women were generally supportive of VMMC, but overcoming barriers with appropriate communication messages and high quality services will be challenging. The justification of circumcision being a biomedical procedure for protection against HIV will be the most important message for any communication strategy.

    Osteoporosis and consequent fracture are not limited to postmenopausal women. There is increasing attention being paid to osteoporosis in older men. Men suffer osteoporotic fractures about 10 years later in life than women, but life expectancy is increasing faster in men than women. Thus, men are living long enough to fracture, and when they do the consequences are greater than in women, with men having about twice the 1-year fatality rate after hip fracture, compared to women. Men at high risk for fracture include those men who have already had a fragility fracture, men on oral glucocorticoids or those men being treated for prostate cancer with androgen deprivation therapy. Beyond these high risk men, there are many other risk factors and secondary causes of osteoporosis in men. Evaluation includes careful history and physical examination to reveal potential secondary causes, including many medications, a short list of laboratory tests, and bone mineral density testing by dual energy X-ray absorptiometry (DXA) of spine and hip. Recently, international organizations have advocated a single normative database for interpreting DXA testing in men and women. The consequences of this change need to be determined. There are several choices of therapy for osteoporosis in men, with most fracture reduction estimation based on studies in women.

    2003-09-01

    Trauma-related nightmares in posttraumatic stress disorder (PTSD) rarely respond to pharmacologic treatment. Neurobiologic data suggest that enhanced brain responsiveness to adrenergic stimulation may contribute to the pathophysiology of trauma-related nightmares in PTSD. Nine older men with chronic PTSD secondary to military or Holocaust trauma were prescribed the lipophilic alpha-1 adrenergic antagonist prazosin for treatment-resistant trauma-related nightmares. Prazosin 2 mg to 4 mg 1 hour before bedtime substantially reduced nightmares and moderately or markedly reduced overall PTSD severity in 8 of 9 subjects. Prazosin was well tolerated. These open-label results are consistent with demonstrated therapeutic efficacy of prazosin for PTSD nightmares and sleep disturbance in a recent placebo-controlled trial in Vietnam veterans.

    Fear of falling (FF) can have multiple adverse consequences in the elderly. Although there are various fall prevention programs, little is known of FF and its associated characteristics. This study examined FF-associated physical and psychosocial factors in older Chinese men living in a veterans home in southern Taiwan. Subjects with a recent episode of delirium, of bed-ridden or wheelchair-bound status, severe hearing impairment or impaired cognition were excluded. Overall, 371 residents (mean age 82.1 ± 5.11 years, all males) participated. The prevalence of FF was 25.3%. Univariate analysis revealed that subjects in the FF group were older age, having lower education level, poorer sitting and standing balance, poorer activities of daily living (ADL), more depressive symptoms, higher chances of using walking aids, neurologic diseases, and a history of fall within the past 6 months. Logistic regression showed that depressive symptoms (odds ratio = OR = 6.73, 95%CI: 3.03-14.93, p FF.

    Objectives. We investigated associations between stress and mental health (positive affect, depressive symptoms) among HIV-negative and HIV-positive midlife and older gay-identified men, along with the mediating and moderating effects of mastery and emotional support. We also studied the mental health effects of same-sex marriage. Methods. We obtained data from self-administered questionnaires completed in 2009 or 2010 by a subsample (n = 202; average age = 56.91 years; age range = 44–75 years) of participants in the University of California, Los Angeles component of the Multicenter AIDS Cohort Study, one of the largest and longest-running natural-history studies of HIV/AIDS in the United States. Results. Both sexual minority stress (perceived gay-related stigma, excessive HIV bereavements) and aging-related stress (independence and fiscal concerns) appeared to have been detrimental to mental health. Sense of mastery partially mediated these associations. Being legally married was significantly protective net of all covariates, including having a domestic partner but not being married. Education, HIV status, and race/ethnicity had no significant effects. Conclusions. Sexual minority and aging-related stress significantly affected the emotional lives of these men. Personal sense of mastery may help to sustain them as they age. We observed specific mental health benefits of same-sex legal marriage. PMID:22390515

    The pineal gland produces the hormone melatonin, and its volume may influence melatonin levels. We describe an innovative method for estimating pineal volume in humans and present the association of pineal parenchyma volume with levels of the primary melatonin metabolite, 6-sulfatoxymelatonin. We selected a random sample of 122 older Icelandic men nested within the AGES-Reykjavik cohort and measured their total pineal volume, their parenchyma volume, and the extent of calcification and cysts. For volume estimations we used manual segmentation of magnetic resonance images in the axial plane with simultaneous side-by-side view of the sagittal and coronal plane. We used multivariable adjusted linear regression models to estimate the association of pineal parenchyma volume and baseline characteristics, including 6-sulfatoxymelatonin levels. We used logistic regression to test for differences in first morning urinary 6-sulfatoxymelatonin levels among men with or without cystic or calcified glands. The pineal glands varied in volume, shape, and composition. Cysts were present in 59% of the glands and calcifications in 21%. The mean total pineal volume measured 207 mm(3) (range 65-536 mm(3)) and parenchyma volume 178 mm(3) (range 65-503 mm(3)). In multivariable-adjusted models, pineal parenchyma volume was positively correlated with 6-sulfatoxymelatonin levels (β = 0.52, p pineal assessment, we found pineal parenchyma volume to be positively correlated with 6-sulfatoxymelatonin levels, in line with other recent studies.

    The role of socioeconomic status in hip fracture incidence is unclear. In a diverse population of elderly, higher education was found to be associated with lower, whereas living alone, compared to being married/cohabiting, with higher hip fracture risk. Educational level and marital status may contribute to hip fracture risk. The evidence on the association between socioeconomic status and hip fracture incidence is limited and inconsistent. We investigated the potential association of education and marital status with hip fracture incidence in older individuals from Europe and USA. A total of 155,940 participants (79 % women) aged 60 years and older from seven cohorts were followed up accumulating 6456 incident hip fractures. Information on education and marital status was harmonized across cohorts. Hip fractures were ascertained through telephone interviews/questionnaires or through record linkage with registries. Associations were assessed through Cox proportional hazard regression adjusting for several factors. Summary estimates were derived using random effects models. Individuals with higher education, compared to those with low education, had lower hip fracture risk [hazard ratio (HR) = 0.84, 95 % confidence interval (CI) 0.72-0.95]. Respective HRs were 0.97 (95 % CI 0.82-1.13) for men and 0.75 (95 % CI 0.65-0.85) for women. Overall, individuals living alone, especially those aged 60-69 years, compared to those being married/cohabiting, tended to have a higher hip fracture risk (HR = 1.12, 95 % CI 1.02-1.22). There was no suggestion for heterogeneity across cohorts (P heterogeneity > 0.05). The combined data from >150,000 individuals 60 years and older suggest that higher education may contribute to lower hip fracture risk. Furthermore, this risk may be higher among individuals living alone, especially among the age group 60-69 years, when compared to those being married/cohabiting.

    Purpose: There is little evidence comparing complications after intensity-modulated (IMRT) vs. three-dimensional conformal radiotherapy (CRT) for prostate cancer. The study objective was to test the hypothesis that IMRT, compared with CRT, is associated with a reduction in bowel, urinary, and erectile complications in elderly men with nonmetastatic prostate cancer. Methods and Materials: We undertook an observational cohort study using registry and administrative claims data from the SEER-Medicare database. We identified men aged 65 years or older diagnosed with nonmetastatic prostate cancer in the United States between 2002 and 2004 who received IMRT (n = 5,845) or CRT (n = 6,753). The primary outcome was a composite measure of bowel complications. Secondary outcomes were composite measures of urinary and erectile complications. We also examined specific subsets of bowel (proctitis/hemorrhage) and urinary (cystitis/hematuria) events within the composite complication measures. Results: IMRT was associated with reductions in composite bowel complications (24-month cumulative incidence 18.8% vs. 22.5%; hazard ratio [HR] 0.86; 95% confidence interval [CI], 0.79-0.93) and proctitis/hemorrhage (HR 0.78; 95% CI, 0.64-0.95). IMRT was not associated with rates of composite urinary complications (HR 0.93; 95% CI, 0.83-1.04) or cystitis/hematuria (HR 0.94; 95% CI, 0.83-1.07). The incidence of erectile complications involving invasive procedures was low and did not differ significantly between groups, although IMRT was associated with an increase in new diagnoses of impotence (HR 1.27, 95% CI, 1.14-1.42). Conclusion: IMRT is associated with a small reduction in composite bowel complications and proctitis/hemorrhage compared with CRT in elderly men with nonmetastatic prostate cancer.

    Concurrent training is an effective method for increasing skeletal muscle performance in aging individuals, but controversy exists as to whether chronic neuromuscular and functional adaptations are affected by the intra-session exercise sequence. Therefore the aim of this study was to evaluate the effect of concurrent endurance and power-like strength training exercise sequence on muscular and functional adaptations of older participants. Thirty-six healthy older men not engaged in systematic exercise training programs for at least 6 months were divided into a control group (CON; 65.8±5.3 years), or in the training groups: endurance-strength (ES; 63.2±3.3 years), or strength-endurance (SE; 67.1±6.1 years). Training groups underwent 12 weeks of concurrent endurance and power-like strength training, starting every exercise session with either endurance (in ES) or strength (in SE) exercises. Measurements included knee extension one repetition maximum (1RM), knee extension power, 30 second sit-to-stand test (30SS), maximum vastus lateralis surface electromyographic activity, and rectus femoris echo intensity (RFEI). Significant increases in maximal strength (ES +18±11.3%; SE +14.2±6.0%; p≤0.05), peak power (ES +22.2±19.4%; SE +26.3±31.3%; p≤0.05), and 30SS performance (ES +15.2±7.2%; SE +13.2±11.8%; p≤0.05) were observed only in the training groups, with no differences between ES and SE. Maximum muscular activity was greater after 12weeks at training groups (p≤0.05), and reductions in RFEI were found only in ES and SE (p≤0.05). These results demonstrate that concurrent strength and endurance training performed twice a week effectively increases muscular performance and functional capacity in older men, independent of the intra-session exercise sequence. Additionally, the RFEI decreases indicate an additional adaptation to concurrent training.

    We tested responses to ozone (O{sub 3}) under simulated {open_quotes}worst-case{close_quotes} ambient exposure conditions. Subjects included 9 men who had severe chronic obstructive pulmonary disease (COPD) with subnormal carbon monoxide diffusing capacity (i.e., an emphysemic component) and 10 age-matched healthy men. Each subject was exposed to 0.24 ppm O{sub 3} and to clean air (control) in an environmentally controlled chamber at 24{degrees}C and 40% relative humidity. Exposures were randomized, they occurred 1 wk apart, and they lasted 4 h. During each half-hour interval, light exercise occurred (e.e., average ventilation 20 l/mm) for 15 min. during both control and O{sub 3} exposures, group mean symptom intensity and specific airway resistance (SRaw) increased, whereas forced expiratory performance decreased. The healthy subgroup`s mean arterial oxygen saturation (SaO{sub 2}) rose slightly, and the COPD subgroup`s mean SaO{sub 2} declined slightly, during exercise. Group mean forced expiratory volume in 1 s (FEV{sub 1.0}) declined significantly in O{sub 3} exposures, compared with controls (p {approx}.01). Mean excess FEV{sub 1.0} loss after 4 h in O{sub 3} (relative to control) was 8% of the preexposure value in the COPD subgroup, compared with 3% in the healthy subgroup (p > .05 [nonsignificant]). Overall FEV{sub 1.0} loss during O{sub 3} exposures, including exercise effects, averaged 19% in the COPD subgroup, compared with 2% in the healthy subgroup (p < .001). Symptoms, SRaw, and SaO{sub 2} responses, as well as healthy subjects` postexposure bronchial reactivity, differed little between O{sub 3}-exposed and control subjects. We therefore concluded that in older men with or without severe COPD, O{sub 3} causes lung dysfunction under {open_quotes}worst-case{close_quotes} ambient exposure conditions, despite older subjects` comparative unresponsiveness to O{sub 3}. 30 refs., 2 figs., 2 tabs.

    The aim of the present study was to examine the relationship between markers of oxidative stress and erythrocyte antioxidant enzyme activity and physical activity in older men and women. The present study included 481 participants (233 men and 248 women) in the age group 65-69 years (127 men and 125 women) and in the age group 90 years and over (106 men and 123 women). The classification of respondents by physical activity was based on answers to the question if, in the past 12 months, they engaged in any pastimes which require physical activity. The systemic oxidative stress status was assessed by measuring plasma iso-PGF2α and protein carbonyl concentration as well as erythrocyte antioxidant enzymes activity, i.e., superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), and glutathione reductase (GR). The concentration of plasma iso-PGF2α and protein carbonyls (CP) was lower in groups of younger men and women compared to the respective older groups. In all examined groups, physical activity resulted in decrease of these oxidative stress markers and simultaneously caused adaptive increase in the erythrocyte SOD activity. Additionally, in active younger men CAT, GPx, and GR activities were higher than in sedentary ones. In conclusion, oxidative stress increase is age-related, but physical activity can reduce oxidative stress markers and induce adaptive increase in the erythrocyte antioxidant enzyme activity, especially SOD, even in old and very old men and women. © 2013.

    Evidence-based health promotion programs are effective at reducing health risks and healthcare costs among older adults, but few men participate in the programs. This mixed methods study aimed to gain insight into the barriers to recruiting and engaging older men in evidence-based health promotion programs offered by the Healthy Aging Regional Collaborative of South Florida (HARC). Fourteen program coordinators participated in a focus group to identify barriers and strategies to improve male participation, and 49 instructors participated in a survey to triangulate the findings. Themes among barriers to male participation included women outnumbering men in the implementation sites and programs, conflict between male gender roles and the programs, and preference for other activities. Themes among strategies included public support of programs by male community leaders, program advertisements featuring males, and adapting program content. Survey results supported themes identified in the focus group. Nearly 78% of the survey respondents agreed that the perception of exercise programs as feminine was a barrier and over 90% of the survey respondents believed program advertisements featuring men would increase male participation. Findings indicate that health promotion programs and recruiting strategies need to be tailored to the unique needs and preferences of older men to improve participation.

    Although numerous studies of non-Hispanic Whites and Blacks show that social integration and social support tend to favor longevity, it is unclear whether this general pattern extends to the Mexican American population. Building on previous research, we employed seven waves of data from the Hispanic Established Populations for the Epidemiologic Study of the Elderly to examine the association between perceived social support trajectories and the all-cause mortality risk of older Mexican Americans. Growth mixture estimates revealed three latent classes of support trajectories: high, moderate, and low. Cox regression estimates indicated that older Mexican American men in the low support trajectory tend to exhibit a higher mortality risk than their counterparts in the high support trajectory. Social support trajectories were unrelated to the mortality risk of older Mexican American women. A statistically significant interaction term confirmed that social support was more strongly associated with the mortality risk of men.

    To determine whether objectively measured physical activity levels are associated with physical function and mobility in older men. Cross-sectional. Academic research center. Eighty-two community-dwelling men aged 65 and older with self-reported mobility limitations were divided into a low-activity and a high-activity group based on the median average daily physical activity counts of the whole sample. Physical activity according to triaxial accelerometers; physical function and mobility according to the Short Physical Performance Battery (SPPB), gait speed, stair climb time, and a lift-and-lower task; aerobic capacity according to maximum oxygen consumption (VO(2) max); and leg press and chest press maximal strength and peak power. Older men with higher physical activity levels had a 1.4-point higher mean SPPB score and a 0.35-m/s faster walking speed than those with lower physical activity levels. They also climbed a standard flight of stairs 1.85 seconds faster and completed 60% more shelves in a lift-and-lower task (all P<.01); muscle strength and power measures were not significantly different between the low- and high-activity groups. Correlation analyses and multiple linear regression models showed that physical activity is positively associated with all physical function and mobility measures, leg press strength, and VO(2) max. Older men with higher physical activity levels demonstrate better physical function and mobility than their less-active peers. Moreover, physical activity levels are predictive of performance in measures of physical function and mobility in older men. Future work is needed to determine whether modifications in physical activity levels can improve or preserve physical performance in later life. © 2010, Copyright the Authors.

    1. A postprandial fall in blood pressure (BP) in older men and women increases the risks of falls and impaired cerebral perfusion. Postprandial hypotension has been suggested to be greater in hypertensive subjects, particularly in those on antihypertensive medication. 2. Caffeine, given as tablets or as strong coffee, may attenuate postprandial falls in BP in older subjects, but findings are not consistent. 3. In a randomized controlled intervention in 171 healthy non-smokers over the age of 50 years, we compared the effects of coffee-drinking with abstaining from caffeine in normotensives (NT), untreated hypertensives (UNHT) and subjects on drug treatment for hypertension (TRHT). Tea drinking was a third intervention used only in TRHT. 4. After adjustment for the effects of the initial value on changes in BP, there were no significant differences related to hypertension or to hypertensive agents in the magnitude of postprandial falls in BP. 5. After the intervention, changes in fasting supine and standing systolic BP and heart rate (HR) were not significantly different from controls in NT, UNHT and TRHT, but fasting supine and standing diastolic BP were significantly higher in coffee drinkers in the UNHT group. 6. In normotensive coffee drinkers there was a significant reduction in the postprandial fall in supine systolic BP of 4.1 mmHg (+/- s.e.m. 1.1) and in standing systolic BP of 5.2 +/- 1.6 mmHg. Among untreated hypertensives, abstainers showed a significant attenuation of the postprandial fall in supine, but not standing, systolic BP. Among treated hypertensives who were tea drinkers the postprandial fall decreased for supine systolic BP by 3.8 +/- 1.2 mmHg (P = 0.029) and for standing systolic BP by 5.2 +/- 2.1 mmHg. 7. Both tea and coffee were potentially beneficial in decreasing postprandial falls in systolic BP, but coffee drinking may increase fasting diastolic pressures in untreated hypertensives.

    Full Text Available The purpose of present research was to investigate the effect of low and moderate intensity aerobic exercises on sleep quality in older adults. The statistical sample included 45 volunteer elderly men with age range of 60-70 years old that divided randomly in two experimental groups (aerobic exercise with low and moderate intensity and one control group. The maximum heart rate (MaxHR of subjects was obtained by subtracting one's age from 220. Furthermore, based on aerobic exercise type (40-50% MaxHR for low intensity group and 60-70% MaxHR for moderate intensity group the target MaxHR was calculated for each subject. The exercise protocol consisted of 8 weeks aerobic exercises (2 sessions in per-week based on Rockport one-mile walking/running test and the control group continued their daily activities. All subjects in per-test and post-test stages were completed the Petersburg Sleep Quality Index (PSQI. Results in post-test stage showed that there were significant differences between control and experimental groups in sleep quality and its components (P<0.05. Also, the Tukey Post Hoc showed that the moderate intensity group scores in sleep quality and its components were better than other groups (P<0.05. Finally, the low intensity group scores were better than control group (P<0.05. Generally, the present research showed that the aerobic exercises with moderate intensity have a positive and significant effect on sleep quality and its components. Thus, based on these findings, the moderate intensity aerobic exercises as a useful and medical method for improve the sleep quality among community older adults was recommended.

    Full Text Available Abstract Background Fragile X syndrome (FXS is the most common inherited form of intellectual disability, and is the most common single-gene disorder known to be associated with autism. Despite recent advances in functional neuroimaging and our understanding of the molecular pathogenesis, only limited neuropathologic information on FXS is available. Methods Neuropathologic examinations were performed on post-mortem brain tissue from three older men (aged 57, 64 and 78 years who had received a clinical or genetic diagnosis of FXS. In each case, physical and cognitive features were typical of FXS, and one man was also diagnosed with autism. Guided by reports of clinical and neuroimaging abnormalities of the limbic system and cerebellum of individuals with FXS, the current analysis focused on neuropathologic features present in the hippocampus and the cerebellar vermis. Results Histologic and immunologic staining revealed abnormalities in both the hippocampus and cerebellar vermis. Focal thickening of hippocampal CA1 and irregularities in the appearance of the dentate gyrus were identified. All lobules of the cerebellar vermis and the lateral cortex of the posterior lobe of the cerebellum had decreased numbers of Purkinje cells, which were occasionally misplaced, and often lacked proper orientation. There were mild, albeit excessive, undulations of the internal granular cell layer, with patchy foliar white matter axonal and astrocytic abnormalities. Quantitative analysis documented panfoliar atrophy of both the anterior and posterior lobes of the vermis, with preferential atrophy of the posterior lobule (VI to VII compared with age-matched normal controls. Conclusions Significant morphologic changes in the hippocampus and cerebellum in three adult men with FXS were identified. This pattern of pathologic features supports the idea that primary defects in neuronal migration, neurogenesis and aging may underlie the neuropathology reported in FXS.

    A prospective observational study was conducted to test the hypothesis that relative deprivation was associated with incident physical or cognitive disability, independent of absolute income. Study subjects consist of 9463 non-disabled people aged 65+ years in the Aichi Gerontological Evaluation Study (AGES), Aichi prefecture, Japan. Baseline mail-in survey in 2003 gathered information on income, educational attainment, lifestyle factors (smoking, alcohol consumption and health check-up) and healthcare utilisation. Three-year incidence of disability was assessed through public long-term care insurance databases and resident registry. A total of 7673 subjects (81%) with complete information were analysed. Our measure of relative deprivation was the Yitzhaki index across eight reference groups, which calculates the deprivation suffered by each individual as a function of the aggregate income shortfall for each person relative to everyone else with higher incomes in that person's reference group. Cox regression demonstrated that, after controlling for sociodemographic factors (including absolute income), the hazard ratio (and 95% confidence intervals) of incident physical/cognitive disability per one standard deviation increase in relative deprivation ranged from 1.13 (0.99 to 1.29) to 1.15 (1.01 to 1.31) in men and from 1.11 (0.94 to 1.31) to 1.18 (1.00 to 1.39) in women, depending on the definition of the reference group. Additional adjustment for lifestyle factors attenuated the hazard ratios to statistical non-significance. Relative deprivation may be a mechanism underlying the link between income inequality and disability in older age, at least among men. Lifestyle factors in part explain the association between relative deprivation and incident disability.

    Objectives Across the lifespan, women live longer than men but experience higher rates of disability. To more completely evaluate these gender differences, the current study set out to compare the trajectories and burden of disability over an extended period of time between older men and women. Design Prospective, longitudinal study with 13.5 years of follow-up. Setting Greater New Haven, Connecticut. Participants 754 persons, aged 70 years or older, who were initially community-living and nondisabled in their basic activities of daily living. Measurements Disability in 13 basic, instrumental and mobility activities was assessed during monthly interviews, while demographic and clinical covariates were measured during comprehensive assessments every 18 months. Results Five distinct trajectories were identified over successive 18-month intervals: independent, mild disability, mild to moderate disability, moderate disability, and severe disability. Women were more likely than men to experience the moderate and severe disability trajectories, but were less likely to transition from the independent trajectory to a worse disability trajectory during the subsequent 18-month interval. Women were also less likely to die after each of the five trajectories, and these differences were at least marginally significant for all but the independent trajectory. Over the entire duration of follow-up, women suffered from a greater burden of disability than men, but these differences were greatly attenuated after adjustment for the baseline levels of disability. Conclusions Gender differences in disability over an extended period of time can be explained, at least in part, by the higher mortality experienced by older men and the higher initial levels of disability among older women. These results suggest the need to take a life-course approach to better understand gender differences in disability. PMID:23294968

    Adults with HIV infection are living into old age. It is critical we investigate positive constructs such as resilience and mastery to determine factors associated with psychological well-being. We examine HIV-related factors, adverse conditions, and psychosocial characteristics that are associated with resilience (the ability to bounce back) and mastery (sense of self-efficacy). We analyzed 2014 data from the longitudinal study Aging with Pride: National Health, Aging, and Sexuality/Gender Study (NHAS), focusing on a subsample of 335 gay and bisexual older men. Multivariate linear regression was used to identify factors that contributed or detracted from resilience and mastery in the sample recruited from 17 sites from across the United States. Resilience and mastery were independently associated with psychological health-related quality of life. In multivariate analysis, adjusting for demographic characteristics, previous diagnosis of depression was negatively associated with resilience. Time since HIV diagnosis was positively associated with mastery whereas victimization was negatively associated with mastery. Social support and community engagement were positively associated with both resilience and mastery. Individual and structural-environmental characteristics contributed to resilience and mastery. These findings can be used to develop interventions incorporating an increased understanding of factors that are associated with both resilience and mastery. © The Author 2017.

    The aging of the human immunodeficiency virus type 1 (HIV-1)–infected population obligates a focus on the interaction between aging, comorbid conditions, and HIV-1. We recruited a cohort of HIV-1–infected men aged ≤35 years or ≥50 years who were receiving fully suppressive antiretroviral therapy (ART). We analyzed plasma markers of inflammation; T-cell activation, exhaustion, proliferation; and innate cellular subsets and functional capacity. Levels of lipopolysaccharide and the plasma marker of chemokine (C-C motif) ligand 2 were significantly elevated in older HIV-infected men despite comparable cellular phenotypes. Compared with similarly age-stratified uninfected subjects, older HIV-1–infected adults were also more frequently in the upper quartile of soluble CD14 expression. PMID:26494772

    The prevalence of depression, erectile dysfunction (ED), and coronary heart disease (CHD) increases with age, and the symptoms related to these three illnesses are closely interlinked. The term "DEC syndrome" is introduced to refer to this triad of comorbid conditions. When a patient presents with one component of the DEC syndrome, physicians should also screen for the other two components. Studies have shown that depression may predispose an individual to an increased risk of developing CHD, and older men with CHD are more likely to be depressed. Likewise, patients with ED are more likely to be clinically depressed, and patients with clinical depression often have ED. Furthermore, patients presenting with ED are often hypertensive, and thus have a significantly higher prevalence of cardiovascular complications. Multifactorial problems require multifactorial approaches, and the care of older men can improve if physicians are aware of this interlinked syndrome.

    Full Text Available Introduction/Purpose: A number of studies have investigated the effect of training with a moderate exercise dose (3–6 h/weekly on the inflammatory profile in blood, and the data are inconsistent. Cross-sectional studies indicate a positive effect of physical activity level on inflammation levels and risk of metabolic disease. However, it is not clear whether this may be dose dependent and if very prolonged repeated exercise therefore may be beneficial for low-grade inflammation. Based on this we studied how excessive repeated prolonged exercise influenced low-grade inflammation and adipose tissue anti-inflammatory macrophage content in six older male recreationally trained cyclists. Low-grade inflammation and adipose tissue macrophage content were investigated in six older trained men (age: 61 ± 4 years; VO2peak: 48 ± 2 mL kg−1 min−1 following repeated prolonged exercise.Methods: Cycling was performed daily for 14 days covering in total 2,706 km (1,681 miles. Maximal oxygen uptake (VO2peak was measured before and after the cycling. Duration and intensity of the exercise were determined from heart rates sampled during cycling. An adipose tissue biopsy from subcutaneous abdominal fat and a blood sample were obtained at rest in the overnight fasted state before and after the cycling. Anti-inflammatory adipose tissue macrophages (ATM were immunohistochemically stained in cross sectional sections using a CD163 binding antibody. The ATM and adipocyte sizes were analyzed blindly.Results: The cyclists exercised daily for 10 h and 31 ± 37 min and average intensity was 53 ± 1% of VO2peak. Body weight remained unchanged and VO2peak decreased by 6 ± 2% (P = 0.04. Plasma inflammatory cytokines, TNFα and IL-18 remained unchanged, as did hsCRP, but plasma IL-6 increased significantly. CD163 macrophage content remained unchanged, as did adipocyte cell size. The HbA1c was not significantly decreased, but there was a trend (P < 0.07 toward an

    Full Text Available Reduced activity of the potent anabolic effectors: insulin-like growth factor-I (IGF-I and fibroblast growth factor-2 (FGF-2, play a role in aging associated muscle loss. The effect of fitness level on IGF-I and FGF-2 responses to all-out anaerobic exercise in older men was studied. Twenty four healthy older males: 12 higher fit (58 ± 1y and 12 lower fit (59 ± 1y underwent the Wingate anaerobic test. Serum levels of IGF-I and FGF-2 were measured before, immediately after exercise, and 50 min into recovery. Immediately post exercise, the average peak power output and serum lactate were higher (p < 0.05 in the higher fit (446.0 ± 14. 9 kgm·min-1 for mean (± SD peak power and 12.6 ± 1.1 mml·l-1 for lactate compared with the lower fit individuals (284.0 ± 6.5 kgm·min-1 and 8.5 ± 0.7 mml·l-1, respectively. Pre-exercise IGF-I was lower and FGF-2 was higher in the higher fit (335.0 ± 54.0 ng·ml-1 and 1.6 ± 0.1 ng·ml-1, respectively compared with lower fit individuals (402.0 ± 50.0 ng·ml-1 and 1.4 ± 0.2 ng·ml-1, respectively. Following the anaerobic exercise, in both groups, FGF-2 decreased dramatically (p < 0.05; in the higher fit individuals FGF-2 level was 0.4 ± 0.1 pg·ml-1 compared to 0.1 ± 0.02 pg·ml-1 in the lower fit individuals. In contrast to FGF-2, IGF-I increased transiently to levels of 405.0 ± 62.0 ng·ml-1 in the higher fit individuals and to levels of 436 ± 57.0 ng·ml-1 in the lower fit individuals. However, the IGF-I elevation was significant (p < 0. 05 only in the higher fit individuals. In conclusion, the present study demonstrates that during aging, fitness level can alter circulating levels of IGF-I and FGF-2. Furthermore, fitness level can affect the response of both mediators to all-out anaerobic exercise.

    Full Text Available Background: An extensive search of the literature found no studies that have examined functional capacity [Activities of Daily Living (ADL and Instrumental Activities for Daily Living (I ADL] of Jamaican older men as well as factors that determine their functional capacity. Aims: The current study examines 1 ADL, 2 (I ADL, 3 self-reported health status, 4 functional capacity, and 5 factors that determine functional capacity of older men. Methods and Method: Stratified multistage probability sampling technique was used to draw a sample of 2,000 55+ year men. A132-item questionnaire was used to collect the data. Descriptive statistics provide background information on the sample, cross tabulations were used to examine non-metric variables and logistic regression provides a model of predictors of functional capacity. Result: Fifty-five percent of sample indicated good current health status. Four percent was mostly satisfied with life; 21.7% had moderate dependence; 77.1% had high dependence (i.e. independence; 1.2% had low dependence; 21.9% were ages 75 years and older; 35.6% were ages 65 to 74 years and 42.6% reported ages 55 to 64 years. Functional capacity can be determined by church attendance (β=0.245; 95% CI: 0.264, 1.291; social support (β=0.129; 95% CI: 0.129, 0.258, area of residence (β=-0.060; 95% CI: -0.427, -0.061 and lastly by age of respondents. Conclusion: Ageing in explains deterioration in their (I ADL, suggesting the challenges of ageing men’s independence. More rural men were rarely satisfied with life; but more of them had a greater functional capacity than urban men. Depression was found to negatively relate to functional capacity, and church attendees had a greater functional status than non-attendees

    This study aims to identify the common risk factors for mortality in community-dwelling older men. A prospective population-based study was conducted with a median of 6.7 years of follow-up. Participants included 1705 men aged ≥70 years at baseline (2005-2007) living in the community in Sydney, Australia. Demographic information, lifestyle factors, health status, self-reported history of diseases, physical performance measures, blood pressure, height and weight, disability (activities of daily living (ADL) and instrumental ADLs, instrumental ADLs (IADLs)), cognitive status, depressive symptoms and blood analyte measures were considered. Cox regression analyses were conducted to model predictors delete time until of mortality. During follow-up, 461 men (27 %) died. Using Cox proportional hazards model, significant predictors of delete time to time to mortality included in the final model (p high blood pressure, hypercholesterolaemia, overweight and obesity and diabetes, were not independent predictors of mortality in this population of older men.

    Importance Most cognitive functions decline with age. Prior studies suggest that testosterone treatment may improve these functions. Objective To determine if testosterone treatment compared with placebo is associated with improved verbal memory and other cognitive functions in older men with low testosterone and age-associated memory impairment (AAMI). Design, Setting, and Participants The Testosterone Trials (TTrials) were 7 trials to assess the efficacy of testosterone treatment in older men with low testosterone levels. The Cognitive Function Trial evaluated cognitive function in all TTrials participants. In 12 US academic medical centers, 788 men who were 65 years or older with a serum testosterone level less than 275 ng/mL and impaired sexual function, physical function, or vitality were allocated to testosterone treatment (n = 394) or placebo (n = 394). A subgroup of 493 men met criteria for AAMI based on baseline subjective memory complaints and objective memory performance. Enrollment in the TTrials began June 24, 2010; the final participant completed treatment and assessment in June 2014. Interventions Testosterone gel (adjusted to maintain the testosterone level within the normal range for young men) or placebo gel for 1 year. Main Outcomes and Measures The primary outcome was the mean change from baseline to 6 months and 12 months for delayed paragraph recall (score range, 0 to 50) among men with AAMI. Secondary outcomes were mean changes in visual memory (Benton Visual Retention Test; score range, 0 to −26), executive function (Trail-Making Test B minus A; range, −290 to 290), and spatial ability (Card Rotation Test; score range, −80 to 80) among men with AAMI. Tests were administered at baseline, 6 months, and 12 months. Results Among the 493 men with AAMI (mean age, 72.3 years [SD, 5.8]; mean baseline testosterone, 234 ng/dL [SD, 65.1]), 247 were assigned to receive testosterone and 246 to receive placebo. Of these groups, 247 men in the

    Gay Community Attachment has proved a significant predictor of successful behavior change among gay-identifying men in response to HIV/AIDS. Related work at Macquarie University, Sydney, Australia, indicated that attachment to gay community is not a simple issue; rather, complex issues of sexual identity formation, the constraints of social inequality and localized sexual cultures inhibit the process of attachment and, therefore, successful HIV prevention. This paper discusses some of the findings from close-focus (qualitative) research on older homosexually active men which explore in depth the dynamic whereby these men attached themselves to gay community in terms of an analysis of class, generation, and the interplay with self-construction and masculinity.

    Age-related increases in ectopic fat accumulation are associated with greater risk for metabolic and cardiovascular diseases, and physical disability. Reducing skeletal muscle fat and preserving lean tissue are associated with improved physical function in older adults. PPARγ-agonist treatment decreases abdominal visceral adipose tissue (VAT) and resistance training preserves lean tissue, but their effect on ectopic fat depots in nondiabetic overweight adults is unclear. We examined the influence of pioglitazone and resistance training on body composition in older (65-79 years) nondiabetic overweight/obese men (n = 48, BMI = 32.3 ± 3.8 kg/m(2)) and women (n = 40, BMI = 33.3 ± 4.9 kg/m(2)) during weight loss. All participants underwent a 16-week hypocaloric weight-loss program and were randomized to receive pioglitazone (30 mg/day) or no pioglitazone with or without resistance training, following a 2 × 2 factorial design. Regional body composition was measured at baseline and follow-up using computed tomography (CT). Lean mass was measured using dual X-ray absorptiometry. Men lost 6.6% and women lost 6.5% of initial body mass. The percent of fat loss varied across individual compartments. Men who were given pioglitazone lost more visceral abdominal fat than men who were not given pioglitazone (-1,160 vs. -647 cm(3), P = 0.007). Women who were given pioglitazone lost less thigh subcutaneous fat (-104 vs. -298 cm(3), P = 0.002). Pioglitazone did not affect any other outcomes. Resistance training diminished thigh muscle loss in men and women (resistance training vs. no resistance training men: -43 vs. -88 cm(3), P = 0.005; women: -34 vs. -59 cm(3), P = 0.04). In overweight/obese older men undergoing weight loss, pioglitazone increased visceral fat loss and resistance training reduced skeletal muscle loss. Additional studies are needed to clarify the observed gender differences and evaluate how these changes in body composition influence functional status.

    The anabolic effects of nutrition on skeletal muscle may depend on adequate skeletal muscle perfusion, which is impaired in older people. Cocoa flavanols have been shown to improve flow-mediated dilation, an established measure of endothelial function. However, their effect on muscle microvascular blood flow is currently unknown. Therefore, the objective of this study was to explore links between the consumption of cocoa flavanols, muscle microvascular blood flow, and muscle protein synthesis (MPS) in response to nutrition in older men. To achieve this objective, leg blood flow (LBF), muscle microvascular blood volume (MBV), and MPS were measured under postabsorptive and postprandial (intravenous Glamin (Fresenius Kabi, Germany), dextrose to sustain glucose ∼7.5 mmol·L(-1)) conditions in 20 older men. Ten of these men were studied with no cocoa flavanol intervention and a further 10 were studied with the addition of 350 mg of cocoa flavanols at the same time that nutrition began. Leg (femoral artery) blood flow was measured by Doppler ultrasound, muscle MBV by contrast-enhanced ultrasound using Definity (Lantheus Medical Imaging, Mass., USA) perflutren contrast agent and MPS using [1, 2-(13)C2]leucine tracer techniques. Our results show that although older individuals do not show an increase in LBF or MBV in response to feeding, these absent responses are apparent when cocoa flavanols are given acutely with nutrition. However, this restoration in vascular responsiveness is not associated with improved MPS responses to nutrition. We conclude that acute cocoa flavanol supplementation improves muscle macro- and microvascular responses to nutrition, independently of modifying muscle protein anabolism.

    Although trials have shown that exercise has positive effects on bone mineral density (BMD), the majority of exercise trials have been conducted in older women. The aim of this study was to systematically review trials examining the effect of weight-bearing and resistance-based exercise modalities on the BMD of hip and lumbar spine of middle-aged and older men. Eight electronic databases were searched in August 2012. Randomised controlled or controlled trials that assessed the effect of weight-bearing and resistance-based exercise interventions on BMD measured by dual-energy x-ray absorptiometry, and reported effects in middle-aged and older men were included. Eight trials detailed in nine papers were included. The interventions included walking (n = 2), resistance training (n = 3), walking + resistance training (n = 1), resistance training + impact-loading activities (n = 1) and resistance training + Tai Chi (n = 1). Five of the eight trials achieved a score of less than 50% on the modified Delphi quality rating scale. Further, there was heterogeneity in the type, intensity, frequency and duration of the exercise regimens. Effects of exercise varied greatly among studies, with six interventions having a positive effect on BMD and two interventions having no significant effect. It appears that resistance training alone or in combination with impact-loading activities are most osteogenic for this population, whereas the walking trials had limited effect on BMD. Therefore, regular resistance training and impact-loading activities should be considered as a strategy to prevent osteoporosis in middle-aged and older men. High quality randomised controlled trials are needed to establish the optimal exercise prescription.

    Background Dementia and affective and psychotic symptoms are commonly associated with Parkinson’s disease, but information about their prevalence and incidence in community representative samples remains sparse. Methods We recruited a community-representative sample 38173 older men aged 65–85 years in 1996 and used data linkage to ascertain the presence of PD, affective disorders, psychotic disorders and dementia. Diagnoses followed the International Classification of Disease coding system. Age was recorded in years. Follow up data were available until December 2011. Results The mean age of participants was 72.5 years and 333 men (0.9%) had PD at study entry. Affective and psychotic disorders and dementia were more frequent in men with than without PD (respective odds ratios: 6.3 [95%CI = 4.7, 8.4]; 14.2 [95%CI = 8.4, 24.0] and 18.2 [95%CI = 13.4, 24.6]). Incidence rate ratios of affective and psychotic disorders were higher among men with than without PD, although ratios decreased with increasing age. The age-adjusted hazard ratio (HR) of an affective episode associated with PD was 5.0 (95%CI = 4.2, 5.9). PD was associated with an age-adjusted HR of 8.6 (95%CI = 6.1, 12.0) for psychotic disorders and 6.1 (95%CI = 5.5, 6.8) for dementia. PD and dementia increased the HR of depressive and psychotic disorders. Conclusions PD increases the risk of affective and psychotic disorders, as well as dementia, among community dwelling older men. The risk of a recorded diagnosis of affective and psychotic disorders decreases with increasing age. PMID:27689715

    Weight loss is associated with bone loss; however, it is unclear whether loss of fat or loss of lean body mass plays the key role in this relationship. The aim of this longitudinal analysis was to clarify the relationship between hip BMD, hip BMC and whole body BMC with changes in fat and lean tissue mass in older men. The Concord Health and Aging in Men Project (CHAMP) is a population-based study in Sydney, Australia, involving 1705 men aged 70-97 years. Bone mineral density (BMD) of the total hip, and bone mineral content (BMC) of the hip and whole body (WB), lean mass and fat mass were measured with Dual X-ray Absorptiometry (DXA). Multivariate linear regression models were used to assess relationships. Over 2.2 years of follow-up, 368(33%) men lost at least 2% of their body weight, which included a mean loss of 0.8 kg/year of lean body mass and 0.9 kg/year of fat body mass. Fat loss was strongly associated with BMD loss in men who lost weight. As a group, weight losers lost 1.0% of hip BMD annually compared to 0.2% in men who gained weight, with each kilo of fat loss associated with 0.6%/year hip BMD loss (ploss in weight losers, however, lean mass change was associated with BMD change in men who gained weight (0.3% hip BMD increase per kilo increase of lean mass pfat plays an important role in this relationship, which may reflect the additional metabolic function of adipose tissue.

    The underlying factors related to the divergent findings of age-related fatigue for dynamic tasks are not well understood. The purpose here was to investigate age-related fatigability and recovery between a repeated constrained (isokinetic) and an unconstrained velocity (isotonic) task, in which participants performed fatiguing contractions at the velocity (isokinetic) or resistance (isotonic) corresponding with maximal power. To compare between tasks, isotonic torque-power relationships were constructed prior to and following both fatiguing tasks and during short-term recovery. Contractile properties were recorded from 9 old (~75 years) and 11 young (~25 years) men during three testing sessions. In the first session, maximal power was assessed, and sessions 2 and 3 involved an isokinetic or an isotonic concentric fatigue task performed until maximal power was reduced by 40 %. Compared with young, the older men performed the same number of contractions to task failure for the isokinetic task (~45 contractions), but 20 % fewer for the isotonic task (p contraction strength, angular velocity, and power were reduced by ~30, ~13, and ~25 %, respectively, immediately following task failure, and only isometric torque was not recovered fully by 10 min. In conclusion, older men are more fatigable than the young when performing a repetitive maximal dynamic task at a relative resistance (isotonic) but not an absolute velocity (isokinetic), corresponding to maximal power.

    The purpose of this study was to investigate the effects of 8weeks at 6g per day of RAR CLA versus placebo on cognitive function and handgrip performance in older men and women. Sixty-five (43 women, 22 men) participants (mean±SD; age=72.4±5.9yrs; BMI=26.6±4.2kg·m(-2)) were randomly assigned to a RAR CLA (n=30: 10 men, 20 women) or placebo (PLA; high oleic sunflower oil; n=35: 12 men, 23 women) group in double-blind fashion and consumed 6g·d(-1) of their allocated supplement for 8weeks. Before (Visit 1) and after supplementation (Visit 2), subjects completed the Serial Sevens Subtraction Test (S7), Trail Making Test Part A (TMA) and Part B (TMB), and Rey's Auditory Verbal Learning Test (RAVLT) to measure cognitive function. The RAVLT included 5, 15-item auditory word recalls (R1-5), an interference word recall (RB), a 6th word recall (R6), and a 15-item visual word recognition trial (RR). For handgrip performance, subjects completed maximal voluntary isometric handgrip strength (MVIC) testing before (MVICPRE) and after (MVICPOST) a handgrip fatigue test at 50% MVICPRE. Hand joint discomfort was measured during MVICPRE, MVICPOST, and the handgrip fatigue test. There were no treatment differences (p>0.05) for handgrip strength, handgrip fatigue, or cognitive function as measured by the Trail Making Test and Serial Seven's Subtraction Test in men or women. However, RAR CLA supplementation improved cognitive function as indicated by the RAVLT R5 in men. A qualitative examination of the mean change scores suggested that, compared to PLA, RAR CLA supplementation was associated with a small improvement in joint discomfort in both men and women. Longer-term studies are needed to more fully understand the potential impact of RAR CLA on cognitive function and hand joint discomfort in older adults, particularly in those with lower cognitive function.

    Although diet quality is implicated in cardiovascular disease (CVD) risk, few studies have investigated the relation between diet quality and the risks of CVD and mortality in older adults. This study examined the prospective associations between dietary scores and risk of CVD and all-cause mortality in older British men. A total of 3328 men (aged 60-79 y) from the British Regional Heart Study, free from CVD at baseline, were followed up for 11.3 y for CVD and mortality. Baseline food-frequency questionnaire data were used to generate 2 dietary scores: the Healthy Diet Indicator (HDI), based on WHO dietary guidelines, and the Elderly Dietary Index (EDI), based on a Mediterranean-style dietary intake, with higher scores indicating greater compliance with dietary recommendations. Cox proportional hazards regression analyses assessed associations between quartiles of HDI and EDI and risk of all-cause mortality, CVD mortality, CVD events, and coronary heart disease (CHD) events. During follow-up, 933 deaths, 327 CVD deaths, 582 CVD events, and 307 CHD events occurred. Men in the highest compared with the lowest EDI quartile had significantly lower risks of all-cause mortality (HR: 0.75; 95% CI: 0.60, 0.94; P-trend = 0.03), CVD mortality (HR: 0.63; 95% CI: 0.42, 0.94; P-trend = 0.03), and CHD events (HR: 0.66; 95% CI: 0.45, 0.97; P-trend = 0.05) but not CVD events (HR: 0.79; 95% CI: 0.60, 1.05; P-trend = 0.16) after adjustment for sociodemographic, behavioral, and cardiovascular risk factors. The HDI was not significantly associated with any of the outcomes. The EDI appears to be more useful than the HDI for assessing diet quality in relation to CVD and morality risk in older men. Encouraging older adults to adhere to the guidelines inherent in the EDI criteria may have public health benefits.

    Correctly identifying other's emotional states is a central cognitive component of empathy. We examined the role of fluid cognitive performance for empathic accuracy for happiness in the daily lives of 86 older couples (mean relationship length = 45 years; mean age = 75 years) on up to 42 occasions over 7 consecutive days. Men performing better on the Digit Symbol test were more accurate in identifying ups and downs of their partner's happiness. A similar association was not found for women. We discuss the potential role of fluid cognitive performance and other individual, partner, and situation characteristics for empathic accuracy. (PsycINFO Database Record

    A limited number of publications have documented the effects of acute alcohol administration among older adults. Among these, only a few have investigated sex differences within this population. The current project examined the behavioral effects of acute low- and moderate-dose alcohol on 62 older (ages 55-70) male and female, healthy, light to moderate drinkers. Participants were randomly assigned to one of three dose conditions: placebo (peak breath alcohol concentration [BrAC] of 0 mg/dL), low (peak BrAC of 40 mg/dL), and moderate (peak BrAC of 65 mg/dL). Tasks assessed psychomotor, set-shifting, and working memory performance. Better set-shifting abilities were observed among women, whereas men demonstrated more efficient working memory, regardless of dose. The moderate-dose group did not significantly differ from the placebo group on any task. However, the low-dose group performed better than the moderate-dose group across measures of set shifting and working memory. Relative to the placebo group, the low-dose group exhibited better working memory, specifically for faces. Interestingly, there were no sex by dose interactions. These data suggest that, at least for our study's task demands, low and moderate doses of alcohol do not significantly hinder psychomotor, set-shifting, or working memory performance among older adults. In fact, low-dose alcohol may facilitate certain cognitive abilities. Furthermore, although sex differences in cognitive abilities were observed, these alcohol doses did not differentially affect men and women. Further investigation is necessary to better characterize the effects of sex and alcohol dose on cognition in older adults.

    Estimates of body-composition change in older adults are mostly derived from cross-sectional data. We examined the natural longitudinal patterns of change in fat-free mass (FFM) and fat mass (FM) in older adults and explored the effect of physical activity, weight change, and age on these changes. The body composition measured by hydrodensitometry and the level of sports and recreational activity (SRA) of 53 men and 78 women with a mean (+/-SD) initial age of 60.7 +/- 7.8 y were examined on 2 occasions separated by a mean (+/-SD) time of 9.4 +/- 1.4 y. FFM decreased in men (2.0% per decade) but not in women, whereas FM increased similarly in both sexes (7.5% per decade). Levels of SRA decreased more in men than in women over the follow-up period. Baseline age and level of SRA were inversely and independently associated with changes in FM in women only. Neither age nor level of SRA was associated with changes in FFM in men or women. Weight-stable subjects lost FFM. FFM accounted for 19% of body weight in those who gained weight, even in the presence of decreased levels of SRA. Loss of FFM (33% of body weight) was pronounced in those who lost weight, despite median SRA levels >4184 kJ/wk. On average, FM increased; however, the increase in women was attenuated with advancing age. The decrease in FFM over the follow-up period was small and masked the wide interindividual variation that was dependent on the magnitude of weight change. The contribution of weight stability, modest weight gains, or lifestyle changes that include regular resistance exercise in attenuating lean-tissue loss with age should be explored.

    Full Text Available Salt intake has been implicated in the pathogenesis of abdominal aortic aneurysm (AAA through studies in rodent models but not previously studied in humans. The aim of this study was to examine the association between reported addition of salt to food and the prevalence of AAA.A risk factor questionnaire which contained a question about salt intake was included as part of a population screening study for AAA in 11742 older men. AAA presence was assessed by abdominal ultrasound imaging using a reproducible protocol.The prevalence of AAA was 6.9, 8.5 and 8.6% in men who reported adding salt to food never, sometimes and always, respectively, p = 0.005. Addition of salt to food sometimes (odds ratio [OR]: 1.22, 95% confidence interval [CI]: 1.03-1.44 or always (OR: 1.23, 95% CI 1.04-1.47 was independently associated with AAA after adjustment for other risk factors including age, waist-hip ratio, blood pressure, history of hypertension, high cholesterol, angina, diabetes, myocardial infarction and stroke. Salt intake was also independently associated with aortic diameter (beta 0.023, p = 0.012. In men with no prior history of hypertension, high cholesterol, angina, myocardial infarction or stroke (n = 4185, the association between addition of salt to food sometimes (OR: 1.41, 95% CI 0.96-2.08 or always (OR: 1.52, 95% CI 1.04-2.22 and AAA remained evident.Reported salt intake is associated with AAA in older men. Additional studies are needed to determine whether reducing salt intake would protect against AAA.

    Full Text Available Several studies on elder abuse indicate that a large number of victims are women, but others report that men in later life are also significantly abused, especially when they show symptoms of disability and poor health, and require help for their daily activities as a result. This study focused on the prevalence of different types of abuse experienced by men and on a comparison of male victims and non-victims concerning demographic/socio-economic characteristics, lifestyle/health variables, social support and quality of life. Additionally, the study identified factors associated with different types of abuse experienced by men and characteristics associated with the victims.The cross-sectional data concerning abuse in the past 12 months were collected by means of interviews and self-response during January-July 2009, from a sample of 4,467 not demented individuals aged between 60-84 years living in seven European countries (Germany, Greece, Italy, Lithuania, Portugal, Spain and Sweden. We used a multilevel approach, within the framework of an Ecological Model, to explore the phenomenon of abuse against males as the complex result of factors from multiple levels: individual, relational, community and societal.Multivariate analyses showed that older men educated to higher levels, blue-collar workers and men living in a rented accommodation were more often victims than those educated to lower levels, low-rank white-collar workers and home owners, respectively. In addition, high scores for factors such as somatic and anxiety symptoms seemed linked with an increased probability of being abused. Conversely, factors such as increased age, worries about daily expenses (financial strain and greater social support seemed linked with a decreased probability of being abused.Male elder abuse is under-recognized, under-detected and under-reported, mainly due to the vulnerability of older men and to social/cultural norms supporting traditional male

    Ageing is associated with frailty and decreased anabolic hormones, insulin-like growth factor-I (IGF-I) and testosterone. We hypothesized that components of the IGF-I system, in conjunction with testosterone, modulate frailty risk in the elderly. We examined associations between IGF-I, its binding proteins IGFBP1 and IGFBP3 and testosterone with frailty in men. Observational study of 3 447 community-dwelling men aged 70-89 years assessed in 2001-04, with 1 654 reassessed in 2008-09. Baseline total IGF-I, IGFBP1, IGFBP3 and testosterone were assayed. Frailty was assessed using the FRAIL scale, comprising 5 domains: fatigue; difficulty climbing stairs; difficulty walking >100 m; >5 illnesses; weight loss >5%. Men with ≥ 3 domains were considered frail. At baseline, 527 men (15·3%) were frail. Frail men had lower IGFBP3 (3 630 ng/ml vs not frail: 3 800 ng/ml, P < 0·001) and comparable IGFBP1 (23·5 vs 21·5 ng/ml, P = 0·09). In multivariate analyses, higher IGFBP1 was associated with increased prevalence of frailty (highest vs lowest quartile Q4:Q1, adjusted odds ratio [OR] = 1·39, 95% CI = 1·03-1·88). New-onset frailty arose in 260 (17·5%) of 1 484 men. Lower baseline IGF-I predicted new-onset frailty (Q1:Q4 OR = 1·48, 95% CI = 1·00-2·20) as did higher IGFBP1 (Q4:Q1 OR = 1·59, 95% CI = 1·01-2·50). Men with both IGF-I and free testosterone in Q1 had greater odds of prevalent frailty (OR = 2·13, 95% CI = 1·54-2·95). Older men with higher IGFBP1 level, or both lower IGF-I and testosterone, are more likely to be frail, while those with lower IGF-I and higher IGFBP1 are more likely to become frail. Components of the IGF-I system may be biomarkers or independent predictors of frailty. © 2012 Blackwell Publishing Ltd.

    Full Text Available The present study determined the effects of muscular endurance strength training on maximum strength and power, functional capacity, muscle activation and hypertrophy in older men and women. Eighty-one men and women acted as an intervention group while 22 acted as non-training controls (age range 64–75 y. Intervention training included super-sets (i.e., paired exercises, immediately performing the second exercises following completion of the first with short rest intervals (30–60 s between sets at an intensity of 50–60% one-repetition maximum (1-RM for 15–20 repetitions. Concentric leg press actions measured maximum strength (1-RM and concentric peak power. Functional capacity was assessed by maximum speed walking tests (i.e., forward walk, backward walk, timed-up-and-go, and stair climb tests. Quadriceps muscle activation was assessed by surface electromyogram and twitch interpolation technique. Vastus lateralis cross-sectional area was measured by panoramic ultrasound. Compared to control, the intervention groups increased maximum strength (1-RM; men: 10 ± 7% vs. 2 ± 3%, women: 14 ± 9% vs. 1 ± 6% both P < 0.01 and vastus lateralis cross-sectional area (men: 6 ± 7% vs. −3 ± 6%, women: 10 ± 10% vs. 0 ± 4% both P < 0.05. But there were no between-group differences in peak power, muscle activation or functional capacity (e.g., stair climb; men: −5 ± 7% vs. −4 ± 3%, women: −5 ± 6% vs. −2 ± 5% both P > 0.05. While benefits occurred during muscular endurance strength training, specific stimuli are probably needed to target all aspects of age-related health.

    Although AIDS mental health research has recently devoted more attention to the psychosocial needs of older adults living with human immunodeficiency virus (HIV) disease, studies of this population have typically combined older African-American and white participants into one large sample, thereby neglecting potential race differences. The current study examined race differences in stressor burden, ways of coping, social support, and psychological distress among late middle-aged and older men living with HIV/AIDS. Self-administered surveys were completed by 72 men living with HIV/AIDS in New York City and Milwaukee, WI (mean age = 53.4 years). Older African-American and white men experienced comparable levels of stress associated with AIDS-related discrimination, AIDS-related bereavement, financial dilemmas, lack of information and support, relationship difficulties, and domestic problems. However, in responses to these stressors, older African-American men more frequently engaged in adaptive coping strategies, such as greater positive reappraisal and a stronger resolve that their future would be better. Compared to their African-American counterparts, HIV-infected older white men reported elevated levels of depression, anxiety, interpersonal hostility, and somatization. African-American men also received more support from family members and were less likely to disclose their HIV serostatus to close friends. As AIDS becomes more common among older adults, mental health-interventions will increasingly be needed for this group. The development of intervention programs for this group should pay close attention to race-related differences in sociodemographic, psychosocial, and behavioral characteristics. PMID:11052457

    In rural western Kenya, older Samia women, often victims of forced marriage in youth, are refusing traditional widow inheritance (remarriage) and renewed male domination after a husband's death. They make their refusals in the strategic public discourse of funeral speeches. The ability of older women to bring about change in female roles and power is related to their positions in extended families and support from 'saved' Christians. Examination of Samia women's everyday resistance to patriarchal power reveals the dynamics of gender relations within the overlapping power structures of kinship hierarchies, marriage, and religion (Christianity). It is also an example of religious renewal as a force in social change.

    A significant proportion of screen-detected men with prostate cancer is likely to be overtreated, especially in older age groups. We aim to find which groups of screen-detected older men (65+) benefit the most from Immediate Radical Treatment or Active Surveillance (AS) for prostate cancer, depending on age, screening history, health status and prostate cancer stage at detection. We used a microsimulation model (MISCAN) of the natural history of prostate cancer based on ERSPC data. Individual life histories are simulated with US comorbidity lifetables based on a random sample of MEDICARE data. Different screening histories are simulated and we count outcomes for men screen-detected from ages 66 to 72. For immediately treated men with low-risk disease (≤ T2a, Gleason 6) the probability of overtreatment ranges from 61% to 86% decreasing to between 37 and 46%, if they are assigned to AS. For intermediate risk men (≤ T2, Gleason 3 + 4) overtreatment ranges from 23 to 60%, which reduces to between 16 and 31% for AS. For high risk men (T3, or ≥ Gleason 4 + 3), overtreatment ranges from 11 to 51%. The disease stage at screen-detection is a critical risk factor for overtreatment. For low risk men, AS seems to significantly reduce overtreatment at a modest cost. For intermediate risk men, the decision between immediate treatment or AS depends on age and comorbidity status. Men screen-detected in a high risk disease stage may benefit from immediate treatment even beyond age 69.

    That many older individuals continue to engage in various forms of sexual expression well into later life is now well established in the literature. To date, however, only a small body of qualitative research has examined older men's experiences and understandings of sex in later life. Likewise, the ways in which older men's discussions on sex may be used as an avenue for "doing" masculinity remain underexplored. Older men are particularly interesting in this regard, as they inhabit an increasingly subordinated position in relation to hegemonic masculine ideals because of their age. To what extent might this limit or, alternatively, open up the possibilities for sexual expression and subjectivity in later life? Drawing on a subset of findings from Sex, Age, and Me: A National Study with Australian Women and Men Aged 60 and Older, data from qualitative interviews with 27 Australian men were explored in this article. The first Australian study of its kind, we argue that older men who engage in heterosexual relationships draw on a diverse and complex array of discursive positions regarding sex, relationships, and masculinity in making sense of their experiences of sex in later life. Older men are a heterogeneous group, and their experiences and understandings of sex do not simplistically follow "decline" or "success" narratives of aging. The findings of this research build upon and extend emerging research illustrating the centrality of intimacy to older men's sexual lives, while simultaneously highlighting the ways in which the body and discursive constructions of sex intersect to shape older men's sexual subjectivities.

    Previous studies have shown that higher aerobic fitness is related to higher cognitive function and higher task-related prefrontal activation in older adults. However, a holistic picture of these factors has yet to be presented. As a typical age-related change of brain activation, less lateralized activity in the prefrontal cortex during cognitive tasks has been observed in various neuroimaging studies. Thus, this study aimed to reveal the relationship between aerobic fitness, cognitive function, and frontal lateralization. Sixty male older adults each performed a submaximal incremental exercise test to determine their oxygen intake (V·O2) at ventilatory threshold (VT) in order to index their aerobic fitness. They performed a color-word Stroop task while prefrontal activation was monitored using functional near infrared spectroscopy. As an index of cognitive function, Stroop interference time was analyzed. Partial correlation analyses revealed significant correlations among higher VT, shorter Stroop interference time and greater left-lateralized dorsolateral prefrontal cortex (DLPFC) activation when adjusting for education. Moreover, mediation analyses showed that left-lateralized DLPFC activation significantly mediated the association between VT and Stroop interference time. These results suggest that higher aerobic fitness is associated with cognitive function via lateralized frontal activation in older adults.

    We examined use of complementary and alternative medicine (CAM) for health and well-being by older women and men. Data were from the 2007 National Health Interview Survey, representing 89.5 million Americans ages 50+. Multivariate logistic regression accounted for the survey design. For general health, 52 million people used CAM. The numbers for immune function, physical performance, and energy were 21.6, 15.9, and 10.1 million respectively. In adjusted results, women were much more likely than men to use CAM for all four reasons, especially energy. Older adults, particularly women, could benefit from research on CAM benefits and risks.

  16. Fertility and sexual life of men after their forties and in older age

    Owing to the demographic development, the aging male will require more consideration in future. In contrast to a rapid decline of estradiol during menopause in women, the process of aging in the male is retarded and subject to high individual variations. Impairment of spermatogenesis is observed as a continuous process occurring over decades. However, only about 50% of men in their eighties show complete loss of fertility. In principle, spermatogenesis may be retained well into senescence. Of importance for the individual health condition is the fact that the number of Leydig cells declines with advancing age. Thus, altered sex hormone concentrations in aging men result from both functional disturbances and a gradual reduction in Leydig cells. Furthermore, an impaired feed-back mechanism of the pituitary-gonadal axis occurs, with disappearance of the circadian testosterone (T) rhythm. LH and FSH levels are increased, and a reduced bioavailability of sex hormones is observed. Lower total testosterone concentrations in men over 60 years are accompanied by clinical signs of reduced virility, such as decreased muscle mass and strength as well as reduced sexual hair growth and libido. An age-related decline in androgen secretion and plasma testosterone levels therefore suggests the use of androgen supplementation. However, there is a lack of risk-benefit long-term studies. Increased research in the male is mandatory to meet the requirements of the aging population. This should include the availability of precise epidemiological data about the frequency of partial androgen deficiency in aging males (PADAM).

    Decline in linguistic function has been associated with decline in cognitive function in previous research. This research investigated the informativeness of written language samples of Australian men from the Health in Men's Study (HIMS) aged from 76 to 93 years using the Computerised Propositional Idea Density Rater (CPIDR 5.1). In total, 60,255 words in 1147 comments were analysed using a linear-mixed model for statistical analysis. Results indicated no relationship with education level (p = 0.79). Participants for whom English was not their first learnt language showed Propositional Idea Density (PD) scores slightly lower (0.018 per 1 word). Mean PD per 1 word for those for whom English was their first language for comments below 60 words was 0.494 and above 60 words 0.526. Text length was found to have an effect (p = <0.0001). The mean PD was higher than previously reported for men and lower than previously reported for a similar cohort for Australian women.

    To present the study design and baseline results of the longitudinal International Mobility in Aging Study (IMIAS) on gender differences in physical performance and mobility disability prevalence in five diverse societies. Data are from surveys on random samples of people aged 65-74 years at Canadian (Kingston, Ontario; Saint-Hyacinthe, Quebec), Mediterranean (Tirana, Albania) and Latin American sites (Natal, Brazil; Manizales, Colombia) (N=1995). Mobility disability was defined as reporting difficulty in walking 400m or climbing stairs. Activities of daily living (ADL) disability was based on any self-reported difficulty in five mobility-related ADLs. The short physical performance battery (SPPB) was used to assess physical performance. Poisson regression models were fitted to estimate prevalence ratios. Age-adjusted prevalence of low SPPB, mobility disability and ADL disability were higher in women than in men in all sites except for Kingston. After adjustment for education and income, gender differences in SPPB and ADL disability attenuated or disappeared in Saint-Hyacinthe and Manizales but remained large in Tirana and Natal and mobility disability remained more frequent in women than in men at all sites except Kingston. After further adjustment by chronic conditions and depressive symptoms, gender differences in mobility remained large at all sites except Kingston but only in Tirana did women have significantly poorer physical performance than men. Results provide evidence for gender as a risk factor to explain poorer physical function in women and suggest that moving toward gender equality could attenuate the gender gap in physical function in old age.

    The examination of mechanisms contributing to the age-related reductions in rapid velocity development is limited. The purpose of this study was to examine the influence of muscle cross-sectional area (CSA) and echo intensity (EI) on plantarflexor rate of velocity development (RVD) in older adults. Twenty-two men (mean ± SD age = 69 ± 3 years) performed three maximal plantarflexion voluntary isokinetic muscle actions at a velocity of 2.09 rad · s(-1). Peak RVD was determined as the peak derivative of the velocity-time curve from the onset of velocity development to the onset of the load range. B-mode ultrasound was used to examine CSA and EI from the lateral and medial gastrocnemius. Plantarflexor RVD was related to EI (r = -0.491, P = 0.020), but not CSA (r = -0.003, P = 0.989). The findings of the present investigation suggest that alterations in muscle tissue composition (i.e., increase in intramuscular fat and/or fibrous tissue) may influence the ability of older adults to rapidly accelerate their limb.

    Living arrangements of older adults have changed worldwide with increasing solitary and non-spouse households, which could affect social care systems. However, the relationship between these households and disability onset has remained unclear. We examined the relationship between living arrangements and the onset of basic activities of daily living disability in older adults, with a focus on gender differences and cohabitation status of those without a spouse. Data from 6600 men and 6868 women aged 65 years or older without disability were obtained from the Aichi Gerontological Evaluation Study Project in Japan. Onset of disability was followed for 9.4 years. Disability was assessed based on Long-term Care Insurance System registration. A hierarchical Cox proportional hazards model was conducted to examine the risk of living alone and living only with non-spousal cohabitants compared to those living with spouses. Men living only with non-spousal cohabitants and those living alone were significantly more likely to develop disability after controlling for health and other covariates (hazard ratio = 1.38 and 1.45, respectively), while a significant difference was found only for women living alone (hazard ratio = 1.19). The risk of living with non-spousal cohabitants was marginally stronger in men, indicated by the interaction effect model (p = .08). A series of hierarchical analyses showed that social support exchange explained 24.4% and 15.8% of the excess risk of disability onset in men living alone and those living only with non-spousal cohabitants, respectively. A subsequent analysis also showed that support provision by older adults more greatly explained such excess risk than receiving support from others. Older men without spouses were more likely to develop disability onset regardless of cohabitants. Health professionals should consider programs that enhance social support exchange, particularly support provision by older adults who are at risk of

    Low levels of 25-hydroxyvitamin D [25(OH)D] and free testosterone (FT) are both associated with increased mortality. Experimental studies show a complex interplay of vitamin D and androgen metabolism suggesting that a deficiency of both hormones may be associated with a particularly adverse clinical outcome. To evaluate the impact of parallel FT and 25(OH)D deficiency in a large cohort of older men. We measured total testosterone (TT), sex hormone-binding globulin and 25(OH)D levels in 2069 men who were routinely referred for coronary angiography (1997-2000). Cox proportional hazard ratios (HRs) (with 95% confidence intervals) for mortality from all causes, cardiovascular and noncardiovascular causes according to combined deficiency of FT and 25(OH)D. In multivariate-adjusted analyses, we found an increased risk for all-cause mortality, cardiovascular and noncardiovascular mortality for men in the lowest FT [HR 1·26 (1·03-1·54), 1·24 (0·96-1·60) and 1·39 (1·00-1·93), respectively] and 25(OH)D quartile [HR 1·77 (1·47-2·13), 1·65 (1·29-2·10) and 1·89 (1·38-2·60) respectively] compared with men in higher FT and 25(OH)D quartiles. There was no independent association of TT levels with mortality. Multivariate-adjusted HRs progressively increased with the number of hormones (FT and 25(OH)D) in the lowest quartile [0 vs 2 hormone deficiencies: 2·11 (1·60-2·79) for all cause, 1·77 (1·23-2·55) for cardiovascular and 2·33 (1·45-3·47) for noncardiovascular mortality, respectively]. A combined deficiency of FT and 25(OH)D is significantly associated with fatal events in a large cohort of men referred for coronary angiography. © 2012 Blackwell Publishing Ltd.

    Forty people over 60 years of age took part in longitudinal research over the course of a year on the impact of the HIV epidemic in southern Uganda. In this paper we focus mainly on the data from 26 of the 40 who were HIV-positive. While we observed that feelings of depression were frequently experienced by many of the people in our study, the state of 'being depressed' was not constant. Participants regularly expressed economic frustration (because of a lack of money to buy food and other commodities including sugar and soap); medical problems (including those related to HIV) as well as old age, the burden of dependents (including concerns about school fees for grandchildren), feelings of sadness and isolation, and a lack of support from others, as well as stigma, whether real or perceived. However, while worries, sorrow and despondent thoughts were reported in many of the interviews across the study, moods fluctuated moving from happiness and hope, to sadness and despair, from month to month. Concerns regarding the psychological wellbeing amongst older people, including those living with HIV and older carers in Uganda deserve greater attention.

    Reduced sleep duration has been increasingly reported to predict obesity. However, timing and regularity of sleep may also be important. In this study, the cross-sectional association between objectively measured sleep patterns and obesity was assessed in two large cohorts of older individuals. Wrist actigraphy was performed in 3053 men (mean age: 76.4 years) participating in the Osteoporotic Fractures in Men Study and 2985 women (mean age: 83.5 years) participating in the Study of Osteoporotic Fractures. Timing and regularity of sleep patterns were assessed across nights, as well as daytime napping. Greater night-to-night variability in sleep duration and daytime napping were associated with obesity independent of mean nocturnal sleep duration in both men and women. Each 1 h increase in the standard deviation of nocturnal sleep duration increased the odds of obesity 1.63-fold (95% confidence interval: 1.31-2.02) among men and 1.22-fold (95% confidence interval: 1.01-1.47) among women. Each 1 h increase in napping increased the odds of obesity 1.23-fold (95% confidence interval: 1.12-1.37) in men and 1.29-fold (95% confidence interval: 1.17-1.41) in women. In contrast, associations between later sleep timing and night-to-night variability in sleep timing with obesity were less consistent. In both older men and women, variability in nightly sleep duration and daytime napping were associated with obesity, independent of mean sleep duration. These findings suggest that characteristics of sleep beyond mean sleep duration may have a role in weight homeostasis, highlighting the complex relationship between sleep and metabolism.

    An inverse relationship between overweight and mortality (the "obesity paradox") is well documented, but there are scarce data on how body weight during the life course affects this relationship. In the Helsinki Businessmen Study, we examined the effect of weight trajectories on incident disability, frailty, and mortality by stratifying 1,114 men (mean age of 47 years in 1974) into the following 4 groups based on body mass index (weight (kg)/height (m)(2)) values measured twice, in 1974 and 2000: 1) constantly normal weight (n = 340, reference group); 2) constantly overweight (n = 495); 3) weight gain (n = 136); and 4) weight loss (n = 143). Twelve-year mortality rates (from 2000 to 2012) and frailty and mobility-related disability in late life were determined. Compared with constantly normal weight, weight loss was associated with disability (odds ratio (OR) = 2.4, 95% confidence interval (CI): 1.1, 4.9) and frailty (OR = 3.7, 95% CI: 1.3, 10.5) in late life. Constant overweight was associated with increased disability (OR = 1.9, 95% CI: 1.1, 3.2). Men with constantly normal weight had the fewest comorbidities in late life (P obesity paradox in late life when earlier weight trajectories were taken into account.

    Active ageing is a key to healthy ageing; shopping behaviour is an economically relevant activity of the elderly. Analysis was based on the NAHSIT 1999-2000 dataset. A total of 1841 representative free-living elderly Taiwanese people were selected and information included demographics, socioeconomic status, health behaviours, shopping frequencies, physical function and cognitive function. These data were linked to official death records. Cox proportional hazard models were used to evaluate shopping frequency on death from 1999-2008 with possible covariate adjustment. Highly frequent shopping compared to never or rarely predicted survival (HR 0.54, 95% CI 0.43 to 0.67) with adjustment for physical function and cognitive function and other covariates HR was 0.73 (95% CI 0.56 to 0.93). Elderly who shopped every day have 27% less risk of death than the least frequent shoppers. Men benefited more from everyday shopping than women with decreased HR 28% versus 23% compared to the least. Shopping behaviour favourably predicts survival. Highly frequent shopping may favour men more than women. Shopping captures several dimensions of personal well-being, health and security as well as contributing to the community's cohesiveness and economy and may represent or actually confer increased longevity.

    Sarcopenia is associated with adverse health outcomes. This study investigated whether skeletal muscle gene expression was associated with lean mass and grip strength in community-dwelling older men. Utilising a cross-sectional study design, lean muscle mass and grip strength were measured in 88 men aged 68-76 years. Expression profiles of 44 genes implicated in the cellular regulation of skeletal muscle were determined. Serum was analysed for circulating cytokines TNF (tumour necrosis factor), IL-6 (interleukin 6, IFNG (interferon gamma), IL1R1 (interleukin-1 receptor-1). Relationships between skeletal muscle gene expression, circulating cytokines, lean mass and grip strength were examined. Participant groups with higher and lower values of lean muscle mass (n = 18) and strength (n = 20) were used in the analysis of gene expression fold change. Expression of VDR (vitamin D receptor) [fold change (FC) 0.52, standard error for fold change (SE) ± 0.08, p = 0.01] and IFNG mRNA (FC 0.31; SE ± 0.19, p = 0.01) were lower in those with higher lean mass. Expression of IL-6 (FC 0.43; SE ± 0.13, p = 0.02), TNF (FC 0.52; SE ± 0.10, p = 0.02), IL1R1 (FC 0.63; SE ± 0.09, p = 0.04) and MSTN (myostatin) (FC 0.64; SE ± 0.11, p = 0.04) were lower in those with higher grip strength. No other significant changes were observed. Significant negative correlations between serum IL-6 (R = -0.29, p = 0.005), TNF (R = -0.24, p = 0.017) and grip strength were demonstrated. This novel skeletal muscle gene expression study carried out within a well-characterized epidemiological birth cohort has demonstrated that lower expression of VDR and IFNG is associated with higher lean mass, and lower expression of IL-6, TNF, IL1R1 and myostatin is associated with higher grip strength. These findings are consistent with a role of proinflammatory factors in mediating lower muscle strength in community-dwelling older men.

    The high relevance of sarcopenia for the aging societies of most developed nations is emphasized by its recent inclusion in the ICD-10-CM (M62.84). However, diagnosing sarcopenia is a daunting task. Apart from varying definitions, the proper assessment of recognized sarcopenia criteria is time and cost consuming. A short and inexpensive screening tool may thus be welcome for clinicians and others working in the area of gerontology. Recently, a simple questionnaire was provided (SARC-F) that may adequately realize this aim. The purpose of this study is to compare established sarcopenia definitions (European Working Group on Sarcopenia in Older People [EWGSOP], Foundation National Institute of Health [FNIH], International Working Group on Sarcopenia [IWGS]) with the SARC-F. Our hypothesis was that the diagnostic overlap between the SARC-F and sarcopenia as determined by these recognized definitions was too low to reliably diagnose sarcopenia. Seventy-four community-dwelling German men aged 70 years and older with established sarcopenia according to EWGSOP and/or FNIH and/or IWGS were screened with the SARC-F questionnaire. Applying the definitions of EWGSOP, IWGS, and FNIH, 66.2, 43.2, and 50% of the cohort were classified sarcopenic, respectively. The SARC-F identified 33.5% of the cohort as sarcopenic. The predictive power of the SARC-F increased when men were classified as sarcopenic according to 2 (57.1%) or all (78.8%) sarcopenia definitions. The diagnostic overlap with the 3 sarcopenia definitions varied between 38.8% (SARC-F-FNIH) and 54.1% (SARC-F-IWGS). In comparison, the overlap of diagnosed sarcopenia ranged from 27.0% (FNIH-IWGS) to 49.0% (IWGS-EWGSOP) among the definitions themselves. Only 12.2% of the men met all 3 sarcopenia definitions. The diagnostic overlap with respect to sensitivity of the SARC-F and present sarcopenia definitions was at least as high as the range of the diagnostic overlap of these approaches themselves. Thus, although the

    This study examined the effects of abilities as a young adult, an engaged lifestyle, personality, age, and health on continuity and change in intellectual abilities from early to late adulthood. A battery of measures, including a verbal and nonverbal intelligence test, was given to 326 Canadian army veterans. Archival data provided World War Two enlistment scores on the same intelligence test for this sample: Results indicated relative stability of intellectual scores across 40 years, with increases in vocabulary and decreases in arithmetic, verbal analogies, and nonverbal skills. Young adult intelligence was the most important determinant of older adult performance. Predictors for verbal intelligence were consistent with an engagement model of intellectual maintenance but also indicated the importance of introversion-extraversion and age. Nonverbal intelligence in late life was predicted by young adult nonverbal scores, age, health, and introversion-extraversion.

    Osteoporosis is a systemic disorder predominantly affecting postmenopausal women but also men at an advanced age. Both genders may suffer from low-energy fractures of, for example, the proximal humerus when reduction of the bone stock or/and quality has occurred.The aim of the current study was to compare the amount of bone in typical fracture zones of the proximal humerus in osteoporotic and non-osteoporotic individuals.The amount of bone in the proximal humerus was determined histomorphometrically in frontal plane sections. The donor bones were allocated to normal and osteoporotic groups using the T-score from distal radius DXA measurements of the same extremities. The T-score evaluation was done according to WHO criteria. Regional thickness of the subchondral plate and the metaphyseal cortical bone were measured using interactive image analysis.At all measured locations the amount of cancellous bone was significantly lower in individuals from the osteoporotic group compared to the non-osteoporotic one. The osteoporotic group showed more significant differences between regions of the same bone than the non-osteoporotic group. In both groups the subchondral cancellous bone and the subchondral plate were least affected by bone loss. In contrast, the medial metaphyseal region in the osteoporotic group exhibited higher bone loss in comparison to the lateral side.This observation may explain prevailing fracture patterns, which frequently involve compression fractures and certainly has an influence on the stability of implants placed in this medial region. It should be considered when planning the anchoring of osteosynthesis materials in osteoporotic patients with fractures of the proximal humerus.

    Full Text Available We examined long-term patterns of stressful life events (SLE and their impact on mortality contrasting two theoretical models: allostatic load (linear relationship and hormesis (inverted U relationship in 1443 NAS men (aged 41–87 in 1985; M = 60.30, SD = 7.3 with at least two reports of SLEs over 18 years (total observations = 7,634. Using a zero-inflated Poisson growth mixture model, we identified four patterns of SLE trajectories, three showing linear decreases over time with low, medium, and high intercepts, respectively, and one an inverted U, peaking at age 70. Repeating the analysis omitting two health-related SLEs yielded only the first three linear patterns. Compared to the low-stress group, both the moderate and the high-stress groups showed excess mortality, controlling for demographics and health behavior habits, HRs = 1.42 and 1.37, ps <.01 and <.05. The relationship between stress trajectories and mortality was complex and not easily explained by either theoretical model.

    Loneliness is a predictor of mortality and increased cardiovascular morbidity. Inflammation is a potential pathway through which loneliness might impact health. The aim of the study was to investigate the relationship between loneliness and inflammatory interleukin-6 (IL-6), interleukin-1 receptor antagonist (IL-1Ra) and monocyte chemotactic protein-1 (MCP-1) responses to standardized mental stress. A secondary purpose was to evaluate whether individual variations in cortisol responses influenced the hypothesised relationship between loneliness and inflammation. Saliva samples and blood were taken from 524 healthy middle-aged men and women from the Whitehall II cohort at baseline, immediately after the stress tasks and 45min later. Loneliness was measured using the revised UCLA loneliness scale. Greater loneliness was associated with larger IL-6 (p=0.044) and IL-1Ra (p=0.006) responses to psychological stress and higher MCP-1 (ploneliness in women, with the odds of being a cortisol responder decreasing with increased loneliness independently of covariates (p=0.008). The impact of loneliness on health in women may be mediated in part through dysregulation of inflammatory and neuroendocrine systems.

    To determine how much physical activity (PA) is needed to protect against diabetes onset in older adults, whether protection is greater among overweight individuals, and whether taking up moderate activity in later life is beneficial. Men (4,252) from a U.K. population-based cohort self-reported usual PA (regular walking and cycling, recreational activity, and sport) in 1996 and in 1998-2000, alongside other health behaviors and medical history. Fasting blood lipids were measured. Median follow-up was 7.1 years, during which 135 cases of type 2 diabetes (validated self-report) occurred. Among 3,012 men free from cardiovascular disease and diabetes in 1998-2000, 9% reported no usual leisure-time PA, 23% occasional PA, and 15% vigorous PA. Compared with men reporting no activity, men reporting occasional, light, moderate, moderately vigorous, and vigorous PA had lower diabetes risks: hazard ratio (HR) 0.58 (95% CI 0.33-1.02), 0.39 (0.20-0.74), 0.38 (0.19-0.73), 0.39 (0.20-0.77), and 0.33 (0.16-0.70), respectively; P (trend) = 0.002, adjusted for age, social class, tobacco, alcohol, diet, and blood lipids. Adjustment for BMI, waist circumference, or fasting insulin attenuated HRs. HRs were stronger in men with BMI ≥28 vs. activity or less in 1996 and 2000, men who became at least moderately active by 2000 or remained at least moderately active at both times had adjusted HRs of 0.62 (0.34-1.12) and 0.51 (0.31-0.82), respectively. Even light PA markedly reduced diabetes risk in older men, especially among the overweight or obese. Taking up or maintaining at least moderate PA in older adulthood strongly protected against diabetes.

    The objective of this study is to examine associations between Hb levels and sarcopenia, low muscle strength, functional measures, and activities of daily living (ADL) and instrumental ADL (IADL) disabilities in older Australian men. Men aged 70 years and older (2005-2007) from the Concord Health and Ageing in Men Project were assessed at baseline (n = 1,705), 2 years (n = 1,367), and 5 years (n = 958). The main outcome measurements were walking speed, muscle strength, ADL and IADL disabilities, and sarcopenia using the Foundation for the National Institutes of Health criteria (low appendicular lean mass adjusted for body mass index sarcopenia, slow walking speed, poor grip strength, inability to perform chair stands, and ADL and IADL disabilities in unadjusted, age-adjusted, and multivariate-adjusted analysis. The highest value of the Youden Index for Hb was 14.2g/dL for sarcopenia and grip strength, 14.5g/dL for walking speed, and 14.4g/dL for all other outcomes. Declines in Hb levels over time are associated with poor functional outcomes. The risks and benefits of interventions to increase Hb among older men warrant further investigation to differentiate whether this is an active contributor to age-related debility or a passive biomarker of it. © The Author 2016.

    Full Text Available Abstract Background Tocopherols may protect against prostate cancer and cardiovascular disease (CVD. Methods We assessed the effect of walnuts, which are rich in tocopherols, on markers of prostate and vascular health in men at risk for prostate cancer. We conducted an 8-week walnut supplement study to examine effects of walnuts on serum tocopherols and prostate specific antigen (PSA. Subjects (n = 21 consumed (in random order their usual diet +/- a walnut supplement (75 g/d that was isocalorically incorporated in their habitual diets. Prior to the supplement study, 5 fasted subjects participated in an acute timecourse experiment and had blood taken at baseline and 1, 2, 4, and 8 h after consuming walnuts (75 g. Results During the timecourse experiment, triglycerides peaked at 4 h, and gamma-tocopherol (γ-T increased from 4 to 8 h. Triglyceride – normalized γ-T was two-fold higher (P = 0.01 after 8 versus 4 h. In the supplement study, change from baseline was +0.83 ± 0.52 μmol/L for γ-T, -2.65 ± 1.30 μmol/L for alpha-tocopherol (α-T and -3.49 ± 1.99 for the tocopherol ratio (α-T: γ-T. A linear mixed model showed that, although PSA did not change, the ratio of free PSA:total PSA increased and approached significance (P = 0.07. The α-T: γ-T ratio decreased significantly (P = 0.01, partly reflecting an increase in serum γ-T, which approached significance (P = 0.08. Conclusion The significant decrease in the α-T: γ-T ratio with an increase in serum γ-T and a trend towards an increase in the ratio of free PSA:total PSA following the 8-week supplement study suggest that walnuts may improve biomarkers of prostate and vascular status.

    2016-11-01

    Full Text Available Aims/hypothesis Existing studies suggest that decreased branched-chain amino acid (BCAA catabolism and thus elevated levels in blood are associated with metabolic disturbances. Based on such information we have developed a hypothesis how BCAA degradation mechanistically connects to tricarboxylic acid (TCA cycle, intramyocellular lipid storage and oxidation thus allowing more efficient mitochondrial energy production from lipids as well as providing better metabolic health. We analyzed whether data from aged Finnish men are in line with our mechanistic hypothesis linking BCAA catabolism and metabolic disturbances. Methods Older Finnish men enriched with individuals having been athletes in young adulthood (n=593; mean age 72.6 ± 5.9 years responded to questionnaires, participated in a clinical examination including assessment of body composition with bioimpedance and gave fasting blood samples for various analytes as well as participated in a 2 hour 75 g oral glucose tolerance test. Metabolomics measurements from serum included BCAAs (isoleucine, leucine and valine.Results Out of the 593 participants 59 had previously known type 2 diabetes, further 67 had screen-detected type 2 diabetes, 127 IGT and 125 IFG while 214 had normal glucose regulation. There were group differences in all of the BCAA concentrations (p≤0.005 for all BCAAs, such that those with normal glucose tolerance had the lowest and those with diabetes mellitus had the highest BCAA concentrations. All BCAA levels correlated positively with body fat percentage (r=.29 - .34, p<.0001 for all. Expected associations with high BCAA concentrations and unfavorable metabolic profile indicators from metabolomics analysis were found. Except for glucose concentrations, the associations were stronger with isoleucine and leucine than with valine. Conclusions/interpretation The findings provided further support for our hypothesis by strengthening the idea that the efficiency of BCAA catabolism

    Relative deprivation of income is hypothesised to generate frustration and stress through upward social comparison with one's peers. If psychosocial stress is the mechanism, relative deprivation should be more strongly associated with specific health outcomes, such as cardiovascular disease (compared with other health outcomes, eg, non-tobacco-related cancer). We evaluated the association between relative income deprivation and mortality by leading causes, using a cohort of 21 031 community-dwelling adults aged 65 years or older. A baseline mail-in survey was conducted in 2003. Information on cause-specific mortality was obtained from death certificates. Our relative deprivation measure was the Yitzhaki Index, derived from the aggregate income shortfall for each person, relative to individuals with higher incomes in that person's reference group. Reference groups were defined according to gender, age group and same municipality of residence. We identified 1682 deaths during the 4.5 years of follow-up. A Cox regression demonstrated that, after controlling for demographic, health and socioeconomic factors including income, the HR for death from cardiovascular diseases per SD increase in relative deprivation was 1.50 (95% CI 1.09 to 2.08) in men, whereas HRs for mortality by cancer and other diseases were close to the null value. Additional adjustment for depressive symptoms and health behaviours (eg, smoking and preventive care utilisation) attenuated the excess risks for mortality from cardiovascular disease by 9%. Relative deprivation was not associated with mortality for women. The results partially support our hypothesised mechanism: relative deprivation increases health risks via psychosocial stress among men. Published by the BMJ Publishing Group Limited.

    Osteoporosis is a common disease causing fracture in older populations. Abnormal apoptosis of osteoblasts contributes to the genesis of osteoporosis. Inhibiting apoptosis of osteoblasts provides a promising strategy to prevent osteoporosis. The proliferation of osteoblasts isolated from osteoporotic patients or healthy subjects was determined by MTT assay. Apoptosis was determined by Annexin V/PI assay. Protein expression was measured by western blot. The proliferation of osteoblasts isolated from osteoporotic patients was inhibited and the apoptosis level of these cells was higher than the osteoblasts from healthy subjects. Incubation with psoralen or estradiol significantly enhanced the proliferation and decreased the apoptosis level of osteoporotic osteoblasts. Western blot demonstrated that psoralen or estradiol treatment downregulated the expression of IRE1, p-ASK, p-JNK, and Bax. Meanwhile, expression of Bcl-2 was upregulated. Pretreatment by IRE1 agonist tunicamycin or JNK agonist anisomycin attenuated the effect of psoralen on osteoporotic osteoblasts. Psoralen inhibited apoptosis of osteoporotic osteoblasts by regulating IRE1-ASK1-JNK pathway.

    This study examined the effect of strength training (ST) and short-term detraining on maximum force and rate of force development (RFD) in previously sedentary, healthy older men. Twenty-four older men (70-80 years) were randomly assigned to a ST group (n = 12) and C group (control, n = 12). Training consisted of three sets of six to ten repetitions on an incline squat at 70-90% of one repetition maximum three times per week for 16 weeks followed by 4 weeks of detraining. Regional muscle mass was assessed before and after training by dual-energy X-ray absorptiometry. Training increased RFD, maximum bilateral isometric force, and force in 500 ms, upper leg muscle mass and strength above pre-training values (14, 25, 22, 7, 90%, respectively; P force and RFD of older men. However, older individuals may lose some neuromuscular performance after a period of short-term detraining and that resistance exercise should be performed on a regular basis to maintain training adaptations.

    Full Text Available Abstract Background There is increasing interest in hormone replacement therapy to improve health and quality of life (QoL of older men with age-related decline in hormone levels. This paper reports the preliminary development and evaluation of the psychometric properties of a new individualised questionnaire, the A-RHDQoL, measuring perceived impact of age-related hormonal decline on QoL of older men. A-RHDQoL design was based on the HDQoL for people with growth hormone (GH deficiency and the ADDQoL (for diabetes. Methods Internal consistency reliability and some aspects of validity of the A-RHDQoL were investigated in a cross-sectional survey of 128 older men (age range: 64 – 80 yrs, being screened for inclusion in a trial of GH and testosterone (T replacement, and who completed the A-RHDQoL once. Respondents rated personally applicable life domains for importance and impact of their hormonal decline. A single overview item measured present QoL. Serum levels of Insulin-like Growth Factor-I and total T were measured. Results Of the 24 A-RHDQoL domains, 21 were rated as relevant and important for older men. All domains were perceived as negatively impacted by hormonal decline. The most negatively impacted domains were: memory (-4.54 ± 3.02, energy (-4.44 ± 2.49, sex life (-4.34 ± 3.08 and physical stamina (-4.29 ± 2.41, (maximum range -9 to +9. The shorter 21-domain A-RHDQoL had high internal consistency reliability (Cronbach's alpha coefficient = 0.935, N = 103 and applicable domains could be weighted and summed into an overall Average Weighted Impact score. The questionnaire was acceptable to the majority of respondents and content validity was good. The single overview item measuring present QoL correlated significantly with total T levels [r = 0.26, p Conclusion The new 21-item A-RHDQoL is an individualised questionnaire measuring perceived impact of age-related hormonal decline on the QoL of older men.

  3. Osteoporotic fractures: a brain or bone disease?

    Science.gov (United States)

    Birge, Stanley J

    2008-06-01

    Osteoporosis is a skeletal disorder that predisposes individuals to increased risk of fracture. However, most osteoporotic fractures occur in women who do not meet criteria for osteoporosis. Hence, bone density, by itself, is a relatively poor predictor of fracture. Age and age-related factors are now recognized as increasingly important in determining fracture risk. Osteoporotic fractures are associated with increased disability and mortality, suggesting that osteoporosis may be a clinical manifestation of an underlying disease process affecting multiple systems. The systems affected, the musculo-skeletal system and the central nervous system, are shared in many respects with the frailty syndrome. Vitamin D deficiency is a major contributor to the frailty syndrome, osteoporosis, and osteoporotic fractures. Its effects are mediated by the development of cerebrovascular disease, postural instability, muscle weakness, and bone fragility. Thus, osteoporotic fractures result from both a bone and brain disease.

    To determine the association of weight loss with risk of clinical fractures at the hip, spine, and pelvis (central body fractures [CBFs]) in older men with and without accounting for the competing risk of mortality, we used data from 4523 men (mean age 77.5 years). Weight change between baseline and follow-up (mean 4.5 years between examinations) was categorized as moderate loss (loss ≥10%), mild loss (loss 5% to models with death as a competing risk. During an average of 8 years, 337 men (7.5%) experienced CBF and 1569 (34.7%) died before experiencing this outcome. Among men with moderate weight loss, CBF probability was 6.8% at 5 years and 16.9% at 10 years using Kaplan-Meier versus 5.7% at 5 years and 10.2% at 10 years using a competing risk approach. Men with moderate weight loss compared with those with stable weight had a 1.6-fold higher adjusted risk of CBF (HR 1.59; 95% CI, 1.06 to 2.38) using Cox models that was substantially attenuated in models accounting for competing mortality risk and no longer significant (subdistribution HR 1.16; 95% CI, 0.77 to 1.75). Results were similar in analyses substituting hip fracture for CBF. Older men with weight loss who survive are at increased risk of CBF, including hip fracture. However, ignoring the competing mortality risk among men with weight loss substantially overestimates their long-term fracture probability and relative fracture risk. © 2016 American Society for Bone and Mineral Research. © 2016 American Society for Bone and Mineral Research.

    We describe levels of sexual activity, problems with sexual functioning, and concerns about sexual health among older adults in the English Longitudinal Study of Ageing (ELSA), and associations with age, health, and partnership factors. Specifically, a total of 6,201 core ELSA participants (56 % women) aged 50 to >90 completed a comprehensive Sexual Relationships and Activities questionnaire (SRA-Q) included in ELSA Wave 6 (2012/13). The prevalence of reporting any sexual activity in the last year declined with age, with women less likely than men at all ages to report being sexually active. Poorer health was associated with lower levels of sexual activity and a higher prevalence of problems with sexual functioning, particularly among men. Difficulties most frequently reported by sexually active women related to becoming sexually aroused (32 %) and achieving orgasm (27 %), while for men it was erectile function (39 %). Sexual health concerns most commonly reported by women related to their level of sexual desire (11 %) and frequency of sexual activities (8 %). Among men it was level of sexual desire (15 %) and erectile difficulties (14 %). While the likelihood of reporting sexual health concerns tended to decrease with age in women, the opposite was seen in men. Poor sexual functioning and disagreements with a partner about initiating and/or feeling obligated to have sex were associated with greater concerns about and dissatisfaction with overall sex life. Levels of sexual activity decline with increasing age, although a sizable minority of men and women remain sexually active until the eighth and ninth decades of life. Problems with sexual functioning were relatively common, but overall levels of sexual health concerns were much lower. Sexually active men reported higher levels of concern with their sexual health and sexual dissatisfaction than women at all ages. Older peoples' sexual health should be managed, not just in the context of their age, gender

    Androgen deprivation therapy (ADT) is an effective treatment for men with advanced prostate cancer, but loss of bone mineral density (BMD) is a major risk factor for fractures. This analysis evaluated the relative effectiveness of osteoporosis treatments using BMD as a surrogate endpoint for fragility fractures in men on continuous ADT. We included randomized controlled trials studying bisphosphonates, denosumab, toremifene, and raloxifene in patients with non-metastatic prostate cancer on ADT for review. Primary outcomes included percentage change in BMD from baseline at total hip, lumbar spine and femoral neck sites. We also recorded incidence rates of any fractures. Network meta-analysis was done to evaluate change in BMD. Out of 270 identified articles, 13 RCTs were included for analysis. The largest BMD improvement compared to placebo at 12 months for total hip site was: raloxifene 3.70% (95% credible interval [CrI], 1.48-5.92%), lumbar spine: zoledronic acid 6.96% (CrI:-5.34-8.52%) and femoral neck: risedronate 6.77% (CrI:-6.87-20.27%). Two studies reported fractures as outcome measure. Toremifene and denosumab studies reported improved incidence of new vertebral fracture outcome vs placebo (2.5% vs 4.9%; p<0.05 and 1.0% vs 3.3%; p=0.004, respectively) at 2-year timepoint. Denosumab and zoledronic acid may have stronger evidence, but all treatments are effective in reducing the rate of bone loss in our patient population. The key policy implication is that men who are at risk for fracture should receive some form of osteoporosis treatment. Choosing the optimal drug should be based on efficacy, safety, product availability, patient preferences and costs. This article is protected by copyright. All rights reserved.

    The purpose of this investigation was to examine the effects of aging and aerobic fitness on exercise- and methylcholine-induced sweating responses during heat acclimation. Five younger [Y group - age: 23+/-1 (SEM) years; maximal oxygen consumption (V.O2max): 47+/-3 ml.kg-1.min-1], four highly fit older (HO group - 63+/-3 years; 48+/-4 ml.kg-1.min-1) and five normally fit older men (NO group - 67+/-3 years; 30+/-1 ml.kg-1.min-1) who were matched for height, body mass and percentage fat, were heat acclimated by daily cycle exercise ( 35% V.O2max for 90 min) in a hot (43°C, 30% RH) environment for 8 days. The heat acclimation regimen increased performance time, lowered final rectal temperature (Tre) and percentage maximal heart rate (%HRmax), improved thermal comfort and decreased sweat sodium concentration similarly in all groups. Although total body sweating rates (M.sw) during acclimation were significantly greater in the Y and HO groups than in the NO group (Prates (m.sw) on chest, back, forearm and thigh changed in all groups by the acclimation. The HO group presented greater forearm m.sw (30-90 min) values and the Y group had greater back and thigh m.sw (early in exercise) values, compared to the other groups (PHO>NO, and on the forearm Y=HO>NO. No group differences were observed for activated sweat gland density at any site. The SGO at the respective sites increased in the post-acclimation test regardless of group (Pincrease was lower in the NO (Pexercised at the same relative exercise intensity. Furthermore, the changes induced by acclimation appear associated with an age-related decrease in V.O2max. However methylcholine-activated SGO and the magnitude of improvement of SGO with acclimation are related not only to V.O2max but also to aging, suggesting that sensitivity to cholinergic stimulation decreases with aging.

    This study investigated the effects of resistance training (RT) performed with different frequencies, including a follow-up period, on cardiorespiratory fitness in healthy older individuals. Eighty-eight men and women (69±3years, 167±9cm and 78±14kg) were randomly placed into four groups: training one- (M1=11, W1=12), two- (M2=7, W2=14), or three- (M3=11, W3=13) times-per-week or a non-training control group (MCon=11, WCon=9). During months 1-3, all subjects trained two-times-per-week while during the subsequent 6months, training frequency was set according to the group. Oxygen consumption (cycling economy: CE), gross efficiency (GE), blood lactate concentrations (La) and heart rate (HR) were evaluated during a submaximal cycle ergometer test. Hemoglobin (Hb), hematocrit (Hct), heart rate (HRrest) and body composition by DXA were also measured at rest. Maximal strength was measured by a 1-RM leg press test. Most improvements in CE, GE, La and HR occurred in all groups during months 1-3. No additional statistically significant improvements were observed during months 4-9, although effect sizes for the change in CE and GE at higher workloads indicated a dose-response pattern in men (CE at 75W: M1 g=0.13, M2 g=-0.58, M3 g=-0.89; 100W: M1 g=0.43, M2 g=-0.59, M3 g=-0.68) i.e. higher training frequency (two- and three-times-per-week versus one-time-per-week) led to greater improvements once the typical plateau in performance had occurred. Hb increased in W1 and W2, while no changes were observed in Hct or HRrest. 1-RM increased from months 1-3 in all intervention groups (except M2) and from month 4-9 only in M3 and in all women intervention groups. During follow-up, maximal strength was maintained but cycling economy returned to the baseline values in all training groups. These data indicate that RT led to significant improvements in cardiorespiratory fitness during the initial 3months of training. This was partly explained by the RT protocol performed but further

    Obesity is increasing, yet despite the necessity of maintaining muscle mass and function with age, the effect of obesity on muscle protein turnover in older adults remains unknown. Eleven obese (BMI 31.9 ± 1.1 kg · m(-2)) and 15 healthy-weight (BMI 23.4 ± 0.3 kg · m(-2)) older men (55-75 years old) participated in a study that determined muscle protein synthesis (MPS) and leg protein breakdown (LPB) under postabsorptive (hypoinsulinemic-euglycemic clamp) and postprandial (hyperinsulinemic hyperaminoacidemic-euglycemic clamp) conditions. Obesity was associated with systemic inflammation, greater leg fat mass, and patterns of mRNA expression consistent with muscle deconditioning, whereas leg lean mass, strength, and work done during maximal exercise were no different. Under postabsorptive conditions, MPS and LPB were equivalent between groups, whereas insulin and amino acid administration increased MPS in only healthy-weight subjects and was associated with lower leg glucose disposal (LGD) (63%) in obese men. Blunting of MPS in the obese men was offset by an apparent decline in LPB, which was absent in healthy-weight subjects. Lower postprandial LGD in obese subjects and blunting of MPS responses to amino acids suggest that obesity in older adults is associated with diminished muscle metabolic quality. This does not, however, appear to be associated with lower leg lean mass or strength.

    The hormonal response of 32 older men (70-80years) to a bout of sub-maximum aerobic exercise was examined before, after 16weeks of resistance or aerobic training and again after 4weeks of detraining. Blood samples were obtained at rest and immediately post sub-maximum exercise (30min @ 70% VO(2) max) to determine the concentrations of growth hormone (GH), insulin-like growth factor-1 (IGF-1), testosterone (Test), sex hormone-binding globulin (SHBG) and the calculation of free testosterone (FT). Both training groups had significant increases in leg strength and VO(2) max after 16weeks training but leg strength and VO(2) max returned to pre-training levels in the aerobic training and resistance training groups, respectively. During the 20week study there was no change in resting concentrations of any hormones among the three groups. There was no increase in GH, IGF-1 or SHBG immediately post sub-maximum exercise in any of the groups before training, after 16weeks training or after 4weeks detraining. Testosterone and FT increased immediately post sub-maximum exercise within all groups before training, after 16weeks training and after 4weeks detraining with the increase in Test and FT higher after 16weeks of resistance training compared to before training and after 4weeks detraining within the resistance training group. The increased responsiveness of Test and FT after 16weeks of resistance training was lost after 4weeks of detraining. Our results indicate that some physiological and hormonal adaptations gained after 16weeks training are lost after only 4weeks detraining.

    Several studies have reported smaller hippocampal volume in patients with depression. However, the temporality of the association is undetermined. One hypothesis is that hippocampal atrophy might be a susceptibility factor for depression. In the present study, we assessed whether hippocampal atrophy was associated with subsequent depressive symptoms in a cohort of older French adults (n = 1,309) who were 65–80 years of age and enrolled into the study in 1999–2001 in Dijon, France. Subjects were followed for more than 10 years. Participants underwent 2 cerebral magnetic resonance imaging scans, one at baseline and one at the 4-year follow-up. We used linear mixed models to estimate the associations of hippocampal atrophy with 1) the average depressive symptom scores over follow-up (using the Center for Epidemiologic Studies-Depression scale) measured biennially over the subsequent 6 years and 2) changes in symptom scores over follow-up. In women, a 2-standard-deviation increase in annual hippocampal atrophy was associated with a 1.67-point (95% confidence interval: 0.59, 2.77) increase in the average depressive symptom score over follow-up and with a 1.97-point (95% confidence interval: 0.68, 3.24) increase in scores over the 2 subsequent years but not with later changes in symptoms. No association was detected in men. Accounting for potential selective attrition (using inverse probability weights) did not alter results. Hippocampal atrophy was associated with more subsequent depressive symptoms and with shorter-term worsening of symptoms in women. PMID:25086051

    Recently, low systolic blood pressure (SBP) was found to be associated with an increased risk of death from vascular diseases in a rural elderly population in Korea. However, evidence on the association between low SBP and vascular diseases is scarce. The aim of this study was to prospectively examine the association between low SBP and mortality from all causes and vascular diseases in older middle-aged Korean men. From 2004 to 2010, 94 085 Korean Vietnam War veterans were followed-up for deaths. The adjusted hazard ratios (aHR) were calculated using the Cox proportional hazard model. A stratified analysis was conducted by age at enrollment. SBP was self-reported by a postal survey in 2004. Among the participants aged 60 and older, the lowest SBP (low SBP was weaker than that in those aged 60 years or older. Our findings suggest that low SBP (<90 mmHg) may increase vascular mortality in Korean men aged 60 years or older.

    To determine the clinical efficacy of percutaneous vertebroplasty in cases of painful and medically intractable osteoporotic vertebral compression fracture. Ninety-eight patients (20 men and 78 women: mean age, 69 years) underwent 122 percutaneous vertebroplasty procedures for the treatment of osteoporotic vertical compression fracture. For the evaluation of bone mass, bone densitometry was performed in 45 patients, and to assess the recent evolution of the fracture, all 98 underwent MRI. Percutaneous vertebroplasty involves percutaneous transpedicular puncture of the involved verteb666rae followed by the injection of a polymethylmethacrylate(PMMA)-Barium mixture into the vertebral body. To assess leakage of the mixture into the epidural tissue, neural foramina, venous plexus and paravertebral tissue, we then immediately obtained a computerized tomographic (CT) scan, assessing the clinical efficacy of the procedure on the basis of time required for pain relief (defined as more than 60% reduction of initial pain), and time required for ambulation without significant pain. Percutaneous vertebroplasty was successful in all patients. Pain relief was accomplished within 1-5 (mean, 1.8) days and early ambulation without significant pain was possible within 2-15 (mean, 3.3) days. Post-procedural CT scanning revealed leakage of the PMMA-barium mixture into paravertebral tissue(n=41).the paravertebral venous plexus (n=34) and epidural tissue (n=4). No neural foraminal leakage was identified, and no procedure-related complication requiring surgical treatment occurred. Percutaneous vertebroplasty is an effective new interventional procedure for the treatment of osteoporotic vertebral compression fracture. It relieves pain, provides early mobilization, and strengthens involved vertebral bodies.

  16. Women Are Diagnosed with Type 2 Diabetes at Higher Body Mass Indices and Older Ages than Men: Korea National Health and Nutrition Examination Survey 2007-2010

    Science.gov (United States)

    2014-01-01

    Background Many epidemiologic studies have shown that women with type 2 diabetes have an increased risk of developing cardiovascular disease compared with men with diabetes. The aim of this study is to elucidate whether disparities of adiposity, age and insulin resistance (IR) at the time of diabetes diagnosis exist between women and men in the adult Korean population. Methods Data from The Korea National Health and Nutrition Examination Survey, performed in Korea from 2007 to 2010, were used. In the survey, anthropometric data and blood samples were obtained during a fasting state. IR and β-cell function were calculated using the homeostasis model assessment (HOMA-IR and HOMA-β, respectvely). Results The mean age of diabetes diagnosis was 58.5 years in women and was 55.1 years in men (P=0.015). The mean body mass index (BMI) of newly diagnosed diabetes subjects was 26.1 kg/m2 in women and 25.0 kg/m2 in men (P=0.001). The BMI was inversely related to age in both genders, and the higher BMI in women than men was consistent throughout all age groups divided by decade. The HOMA-IR in women with diabetes is higher than in men with diabetes (7.25±0.77 vs. 5.20±0.32; P=0.012). Conclusion Korean adult women are diagnosed with type 2 diabetes at higher BMI and older age than men and are more insulin-resistant at the time of diabetes diagnosis. This may help explain why women with diabetes have an increased risk of developing cardiovascular disease after the diagnosis of diabetes, compared to men. PMID:24627831

  19. Inhibition of Midkine Augments Osteoporotic Fracture Healing.

    Directory of Open Access Journals (Sweden)

    Melanie Haffner-Luntzer

    Full Text Available The heparin-binding growth and differentiation factor midkine (Mdk is proposed to negatively regulate osteoblast activity and bone formation in the adult skeleton. As Mdk-deficient mice were protected from ovariectomy (OVX-induced bone loss, this factor may also play a role in the pathogenesis of postmenopausal osteoporosis. We have previously demonstrated that Mdk negatively influences bone regeneration during fracture healing. Here, we investigated whether the inhibition of Mdk using an Mdk-antibody (Mdk-Ab improves compromised bone healing in osteoporotic OVX-mice. Using a standardized femur osteotomy model, we demonstrated that Mdk serum levels were significantly enhanced after fracture in both non-OVX and OVX-mice, however, the increase was considerably greater in osteoporotic mice. Systemic treatment with the Mdk-Ab significantly improved bone healing in osteoporotic mice by increasing bone formation in the fracture callus. On the molecular level, we demonstrated that the OVX-induced reduction of the osteoanabolic beta-catenin signaling in the bony callus was abolished by Mdk-Ab treatment. Furthermore, the injection of the Mdk-Ab increased trabecular bone mass in the skeleton of the osteoporotic mice. These results implicate that antagonizing Mdk may be useful for the therapy of osteoporosis and osteoporotic fracture-healing complications.

    Older men have lower T levels, but whether differences in circulating T or its metabolites dihydrotestosterone (DHT) or estradiol (E2) contribute to cardiovascular disease remains controversial. We tested the hypothesis that plasma T, DHT, and E2 are differentially associated with the incidence of myocardial infarction (MI) and stroke in older men. Plasma total T, DHT, and E2 were assayed using liquid chromatography-mass spectrometry in early-morning samples from 3690 community-dwelling men aged 70-89 years. Outcomes of the first hospital admission or death due to MI or stroke were ascertained by data linkage. Mean follow-up was 6.6 years. Incident MI occurred in 344, stroke in 300, and neither in 3046 men. In a multivariate analysis adjusting for age and other risk factors, T, DHT, and E2 were not associated with incident MI [fully adjusted hazard ratio (HR) for T in quartile (Q) 4 vs Q1: 0.92, 95% confidence interval (CI) 0.66-1.28; DHT: 0.83, 95% CI 0.59-1.15; E2: 0.84, 95% CI 0.62-1.15]. Higher T or DHT was associated with a lower incidence of stroke (T: Q4: Q1 fully adjusted HR 0.56, 95% CI 0.39-0.81, P = .002; DHT: 0.57, 95% CI 0.40-0.81, P = .002). E2 was not associated with stroke (HR 0.76, 95% CI 0.54-1.08, P = .123). Higher plasma T or DHT is a biomarker for reduced risk of stroke but not MI. Androgen exposure may influence outcomes after rather than the incidence of MI, whereas androgens but not E2 are independent predictors of stroke risk. Randomized clinical trials are needed to clarify the impact of modifying T or DHT on the risk of stroke in aging men.

    Full Text Available Objective. To investigate effects of weight loss on adipokines and health measures in obese older adults with symptomatic knee osteoarthritis. Methods. Participants were randomly assigned to either weight loss (WL (men: 12, women: 14 or weight stable (WS group (men: 12, women: 13. WL intervention included meal replacements and structured exercise training. Measurements of leptin, adiponectin, soluble leptin receptor, lifestyle behaviors, and body composition were collected at baseline and 6 months. Univariate analysis of covariance was performed on 6 month variables, and Spearman and partial correlations were made between variables. Results. Weight loss was 13.0% and 6.7% in WL for men and women, respectively. Women in WL had lower whole body and trunk fat than WS. The leptin : adiponectin ratio was lower for women in WL than WS at 6 months, with no group differences in adipokines for men. Leptin and free leptin index correlated with body fat in both genders at baseline. Interestingly, only women showed reductions in leptin (P<0.100 and correlations between the percentage change leptin and trunk fat and the percentage changes in free leptin index with total fat and trunk fat. Partial correlations between 6 month adipokines after adjustments for covariates and group/time period show potential multivariate influences. Conclusions. In the presence of an effective weight loss intervention in older obese adults, there are significant relationships between weight and fat loss and leptin in women, but not men, suggesting gender-specific features of adipokine metabolism in this age group.

    Osteoporosis has finally been recognized as an important disorder in men. Men have osteoporotic fractures about 10 years later in life than women. Owing to increasing life expectancy, more fractures are predicted. Important risk factors for men include advancing age, smoking or chronic obstructive pulmonary disease, glucocorticoid therapy, and androgen deprivation therapy for prostate cancer. Other groups at risk for osteoporosis include those with alcohol abuse, men on enzyme-inducing antise...

  3. Does growth hormone therapy in conjunction with resistance exercise increase muscle force production and muscle mass in men and women aged 60 years or older?

    1999-01-01

    Improved muscle protein mass and increments in maximum voluntary muscle force have rarely been observed in men and women aged 60 years and older who were treated with rhGH. Although rhGH administration has been reported to increase lean body mass in older men and women, it is doubtful that this increase is localized to skeletal muscle contractile proteins. When rhGH administration was combined with 16 weeks of resistance exercises, increases in muscle mass, muscle protein synthesis, and muscle force were not greater in the rhGH-treated group than in a weight training group that received placebo injections. Side effects of rhGH treatment in elderly people are prevalent, not trivial, and further limit its usefulness as an effective anabolic agent for promoting muscle protein accretion in men and women. In particular, the induction of insulin resistance and carpal tunnel compression reduces the efficacy of rhGH replacement therapy in elderly individuals. The evidence for a GH-induced increase in human skeletal muscle protein and maximum voluntary muscle force is weak. The optimum dose and GH-replacement paradigm (GHRH, GH-secretagogues) have not been identified. Whether rhGH therapy improves muscle protein mass and force in individuals with severe cachexia associated with major trauma, burns, surgery, or muscular dystrophy is controversial and under investigation.

    Full Text Available To determine age- and sex-specific body composition reference values and investigate age differences in these parameters for community-dwelling older Japanese men and women, using direct segmental multi-frequency bioelectrical impedance analysis.We conducted a pooled analysis of data collected in four cohort studies between 2008 and 2012: Kusatsu Longitudinal Study, Hatoyama Cohort Study, Itabashi Cohort Study, and Kashiwa Cohort Study. The pooled analysis included cross-sectional data from 4478 nondisabled, community-dwelling adults aged 65-94 years (2145 men, 2333 women; mean age: 72.9 years in men and 72.6 years in women. Body weight, fat mass (FM, percentage FM, fat-free mass (FFM, and appendicular lean soft tissue mass were measured using the InBody 720 and 430 (Biospace Co. Ltd, Seoul, Korea. The values were then normalized by height in meters squared to determine body mass index (BMI, FM index (FMI, FFM index (FFMI, and skeletal muscle mass index (SMI.Simple means (standard deviation of BMI, percentage FM, FMI, FFMI, and SMI were 23.4 (2.9 kg/m(2, 24.9 (6.3%, 5.96 (2.09 kg/m(2, 17.4 (1.5 kg/m(2, and 7.29 (0.76 kg/m(2, respectively, in men and 22.7 (3.3 kg/m(2, 31.7 (7.1%, 7.40 (2.61 kg/m(2, 15.3 (1.2 kg/m(2, and 5.86 (0.67 kg/m(2, respectively, in women. We then calculated quartiles and quintiles for these indices after stratifying for sex and 5-year age group. FFMI and SMI decreased significantly with age in both sexes (P < 0.001 for trends, but FFMI remained constant among the women with only a 1% decrease up to age 84 years. Percentage FM increased significantly, with age (P < 0.001 in men and P = 0.045 in women for trends, but FMI was unchanged in both sexes (P = 0.147 in men and P = 0.176 in women for trends.The present data should be useful in the clinical evaluation of body composition of older Japanese and for international comparisons. The small age-related decrease in FFMI may be a noteworthy characteristic of body composition

    Full Text Available Abstract Background It has been demonstrated that endothelins (ET have significant roles in bone remodeling, metabolism and physiopathology of several bone diseases. We aimed to investigate if there was any difference between the plasma ET levels of osteoporotic patients and normals. Methods 86 patients (70 women and 16 men with a mean age of 62.6 (ranges: 51–90 years were included in this study. Patients were divided into groups of osteoporosis, osteopenia and normal regarding reported T scores of DEXA evaluation according to the suggestions of World Health Organization. According to these criteria 19, 43 and 24 were normal, osteopenic and osteoporotic respectively. Then total plasma level of ET was measured in all patients with monoclonal antibody based sandwich immunoassay (EIA method. One-way analysis of variance test was used to compare endothelin values between normals, osteopenics and osteoporotics. Results Endothelin total plasma level in patients was a mean of 98.36 ± 63.96, 100.92 ± 47.2 and 99.56 ± 56.6 pg/ml in osteoporotic, osteopenic and normal groups respectively. The difference between groups was not significant (p > 0.05. Conclusion No significant differences in plasma ET levels among three groups of study participants could be detected in this study.

    Osteoporosis is a serious public health problem affecting hundreds of millions of aged people worldwide, with severe consequences including vertebral fractures that are associated with significant morbidity and mortality. To augment or treat osteoporotic vertebral fractures, a number of surgical approaches including minimally invasive vertebroplasty and kyphoplasty have been developed. However, these approaches face problems and difficulties with efficacy and long-term stability. Recent advances and progress in nanotechnology are opening up new opportunities to improve the surgical procedures for treating osteoporotic vertebral fractures. This article reviews the improvements enabled by new nanomaterials and focuses on new injectable biomaterials like bone cements and surgical instruments for treating vertebral fractures. This article also provides an introduction to osteoporotic vertebral fractures and current clinical treatments, along with the rationale and efficacy of utilizing nanomaterials to modify and improve biomaterials or instruments. In addition, perspectives on future trends with injectable bone cements and surgical instruments enhanced by nanotechnology are provided.

    Male sexual function is highly androgen dependent but whether aromatization of testosterone (T) to estradiol is required remains contentious. This study aims to investigate the effects of selective estrogen deficiency induced by a nonaromatizable androgen, dihydrotestosterone (DHT), on sexual function of healthy middle-aged and older men. Randomized clinical trial of daily transdermal DHT (70 mg) or placebo gel treatment in 114 healthy middle-aged and older (>50 years, mean 60.5 years) men without known prostate disease maintaining selective estrogen deficiency for 24 months. The end points were responses to a psychosexual and mood questionnaire completed before, at 3 months, then at 6 monthly intervals during and 3 months after study. Data were analyzed by mixed model analysis of variance for repeated measures using age and body mass index (BMI) as covariates and including interactions of treatment with age and time-on-study. DHT treatment increased serum DHT with complete suppression of serum T, luteinizing hormone, follicle stimulating hormone, and estradiol throughout the 24-month study resulting in reduced spinal bone density. There were no spontaneous complaints, or discontinuations for, adverse effects on sexual function during the study. DHT administration had no effects on any of 33 measures of sexual function and mood, apart from a mild, but significant decrease in overall sexual desire, which was reversible after cessation of treatment. Increasing age and less often increasing BMI were associated with significant decreases in most aspects of sexual function. We conclude that aromatization plays only a minimal role in maintenance of sexual function in healthy eugonadal middle-aged or older men, but age and obesity are significantly associated with decreases in most aspects of self-reported sexual function and satisfaction. The dependence of male sexual function on aromatization may be conditional on age and obesity and can be overcome by a

    There is intense interest in examining hospital mortality in relation to gender in ST-segment elevation myocardial infarction. The aim of the present study was to determine whether gender influences outcomes in men and women treated with the same patency-oriented reperfusion strategy. The influence of gender on hospital mortality was tested using multivariate analysis and local regression. The influence of age was tested as a continuous and as a categorical variable. In the overall population of 2,600 consecutive patients, gender was not correlated with hospital mortality except in the subgroup of women aged ≥65 years. The risk for death increased linearly in logit scale for men. Up to the age of 65 years, the risk also increased linearly in women but thereafter increased faster than in men. Testing age as a categorical variable, hospital mortality was higher in women than in men aged ≥75 years but was similar between the genders in the younger age categories. In conclusion, despite following an equal patency-oriented management strategy in men and women with ST-segment elevation myocardial infarctions, the risk for hospital death increased linearly with age but with an interaction between age and gender such that older women had an independent increase in hospital mortality. Longer time to presentation and worse baseline characteristics probably contributed to determine a high-risk subset but reinforce the need to apply, as recommended in the international guidelines in the management of patients with ST-segment elevation myocardial infarctions, the same strategy of acute reperfusion in men and women.

    Full Text Available Abstract Background Recent studies have revealed the associations between insulin resistance (IR and geriatric conditions such as frailty and cognitive impairment. However, little is known about the relation of IR to physical impairment and limitation in the aging process, eg. slow gait speed and poor muscle strength. The aim of this study is to determine the effect of IR in performance-based physical function, specifically gait speed and leg strength, among nondiabetic older adults. Methods Cross-sectional data were from the population-based National Health and Nutrition Examination Survey (1999-2002. A total of 1168 nondiabetic adults (≥ 50 years with nonmissing values in fasting measures of insulin and glucose, habitual gait speed (HGS, and leg strength were analyzed. IR was assessed by homeostasis model assessment (HOMA-IR, whereas HGS and peak leg strength by the 20-foot timed walk test and an isokinetic dynamometer, respectively. We used multiple linear regression to examine the association between IR and performance-based physical function. Results IR was inversely associated with gait speed among the men. After adjusting demographics, body mass index, alcohol consumption, smoking status, chronic co-morbidities, and markers of nutrition and cardiovascular risk, each increment of 1 standard deviation in the HOMA-IR level was associated with a 0.04 m/sec decrease (p = 0.003 in the HGS in men. We did not find such association among the women. The IR-HGS association was not changed after further adjustment of leg strength. Last, HOMA-IR was not demonstrated in association with peak leg strength. Conclusion IR is inversely associated with HGS among older men without diabetes. The results suggest that IR, an important indicator of gait function among men, could be further investigated as an intervenable target to prevent walking limitation.

    Oxidative stress is an important factor in the pathology of age-related hearing loss. Recent animal studies have reported that ultraviolet radiation in sunlight is related to systemic induction of oxidative stress. Chronic sun exposure leads to photodamaged skin, which is manifested as facial skin wrinkling and hyperpigmentation. We hypothesized that sunlight exposure, as assessed by the severity of facial skin photodamage, might be associated with hearing impairment through an oxidative stress mechanism. To examine this, we performed a cross-sectional analysis by using the baseline data from a community-based cohort study of older Japanese. A total of 805 residents (342 men and 463 women) aged 65 years or older living in Kurabuchi Town, Gunma prefecture, Japan, were examined between 2005 and 2006. Facial skin condition was quantified by image analysis of standardized facial images. Hearing impairment was defined as a failure to hear a 30-dB signal at 1 kHz and a 40-dB signal at 4 kHz in the better ear in pure-tone audiometric tests. In men, facial wrinkle was positively associated with hearing impairment (for highest vs lowest: multivariate-adjusted odds ratio, 2.16; 95% confidence interval, 1.00-4.66; p for trend = .01). Stratified analysis by age, educational level, smoking status, sunscreen or foundation use, and diabetes showed results similar to those for men as a whole. This association was particularly pronounced in men with the low levels of antioxidants and without occupational noise exposure. We observed no apparent association in women. The results support the hypothesis that chronic sun exposure is a risk factor of hearing impairment.

    Older HIV-infected men are at higher risk for both depression and cognitive impairments, compared to HIV-uninfected men. We evaluated the association between longitudinal patterns of depressive symptoms and attention/executive function in HIV-infected and HIV-uninfected men aged 50+ years to understand whether HIV infection influenced the long-term effect of depression on attention/executive function. Responses to the Center for Epidemiologic Studies-Depression scale and attention/executive function tests (Trail Making Test Part B and Symbol Digit Modalities Test) were collected semiannually from May 1986 to April 2015 in 1611 men. Group-based trajectory models, stratified by HIV status, were used to identify latent patterns of depressive symptoms and attention/executive function across 12 years of follow-up. We identified three depression patterns for HIV-infected and HIV-uninfected men (rare/never 50.0 vs. 60.6%, periodically depressed 29.6 vs. 24.5%, chronic high 20.5 vs.15.0%, respectively) and three patterns of attention/executive function for HIV-infected and HIV-uninfected men (worst-performing 47.4 vs. 45.1%; average 41.9 vs. 47.0%; best-performing 10.7 vs. 8.0%, respectively). Multivariable logistic regression models were used to assess associations between depression patterns and worst-performing attention/executive function. Among HIV-uninfected men, those in the periodically depressed and chronic high depressed groups had higher odds of membership in the worst-performing attention/executive function group (adjusted odds ratio [AOR] = 1.45, 95% CI 1.04, 2.03; AOR = 2.25, 95% CI 1.49, 3.39, respectively). Among HIV-infected men, patterns of depression symptoms were not associated with patterns of attention/executive function. Results suggest that HIV-uninfected, but not HIV-infected, men with chronic high depression are more likely to experience a long-term pattern of attention/executive dysfunction.

    Full Text Available Sheryl F Vondracek, Sunny A LinneburDepartment of Clinical Pharmacy, School of Pharmacy C238-L15, University of Colorado Denver, Aurora, CO, USAAbstract: The older senior is at high risk for osteoporosis. It is important for healthcare providers to be fully aware of the potential risks and benefits of diagnosing and treating osteoporosis in the older senior population. Data indicate that bone mineral density testing is under-utilized and drug therapy is often not initiated when indicated in this population. Bone mineral density testing with central dual energy x-ray absorptiometry is essential and cost-effective in this population. All older seniors should be educated on a bone-healthy lifestyle including age-appropriate weightbearing exercise and smoking cessation if necessary. It is important to remember that falls play a very important role in the risk for osteoporotic fractures, especially in the older senior. All older seniors should be evaluated annually for falls and strategies should be implemented to reduce fall risk in this population. The risk for vitamin D insufficiency and deficiency is high in the older senior and can contribute to falls and fractures. Adequate intakes of calcium and vitamin D are important and deficiencies need to be treated. Data on osteoporosis drug therapy in the older senior are lacking. Based on data from subgroup analyses of large osteoporosis trials in postmenopausal women, current osteoporosis therapies appear safe and efficacious in the older senior and most will live long enough to derive a benefit from these therapies. Further studies are needed in older seniors, especially men, to better understand the risks and benefits of pharmacologic therapy for the management of osteoporosis.Keywords: osteoporosis, aged, elderly, eighty and over, senior, diphosphonates

    Background: Moderate intake of alcohol has been reported to have beneficial effects on bone. However, different classes of alcoholic beverages have not been investigated. Objective: Our aim was to determine the association between intake of total alcohol or individual alcoholic beverages and bone mineral density (BMD). Design: Adjusting for potential confounding factors, we examined alcohol intakes and BMD at 3 hip sites and the lumbar spine in 1182 men and in 1289 postmenopausal and 248 premenopausal women in the population-based Framingham Offspring cohort (age: 29–86 y). Results: Men were predominantly beer drinkers, and women were predominantly wine drinkers. Compared with nondrinkers, hip BMD was greater (3.4–4.5%) in men consuming 1–2 drinks/d of total alcohol or beer, whereas hip and spine BMD were significantly greater (5.0–8.3%) in postmenopausal women consuming >2 drinks/d of total alcohol or wine. Intake of >2 drinks/d of liquor in men was associated with significantly lower (3.0–5.2%) hip and spine BMD than was intake of 1–2 drinks/d of liquor in men. After adjustment for silicon intake, all intergroup differences for beer were no longer significant; differences for other alcohol sources remained significant. Power was low for premenopausal women, and the associations were not significant. Conclusions: Moderate consumption of alcohol may be beneficial to bone in men and postmenopausal women. However, in men, high liquor intakes (>2 drinks/d) were associated with significantly lower BMD. The tendency toward stronger associations between BMD and beer or wine, relative to liquor, suggests that constituents other than ethanol may contribute to bone health. Silicon appears to mediate the association of beer, but not that of wine or liquor, with BMD. Other components need further investigation. PMID:19244365

    Older adults have low physical activity(PA) and high sedentary behaviour(SB) levels. We investigate how total volume and specific patterns of moderate to vigorous PA(MVPA), light PA(LPA) and SB are related to adiposity and metabolic syndrome (MS). Then, with reference to physical activity guidelines which encourage MVPA in bouts > =10 min and avoiding "long" sedentary bouts, we investigate whether accumulating PA and SB in bouts of different defined durations are differently associated with these outcomes. Cross-sectional study of men (71-91 years) recruited in UK primary care centres. Nurses made physical measures (weight, height, bio-impedance, blood pressure) and took fasting blood samples. 1528/3137 (49%) surviving men had ≥3 valid days (≥600 min) accelerometer data. 450 men with pre-existing chronic disease were excluded. 1009/1078 (93.6%) had complete covariate data. Men (n = 1009, mean age 78.5(SD 4.7) years) spent 612(SD 83), 202(SD 64) and 42(SD 33) minutes in SB, LIPA and MVPA respectively. Each additional 30 min/day of SB and MVPA were associated with 0.32 (95% CI 0.23, 0.40)Kg/m(2) higher Body Mass Index (BMI) and -0.72(-0.93, -0.51) lower BMI Kg/m(2) respectively. Patterns for waist circumference (WC), fat mass index (FMI), fasting insulin and MS were similar. MVPA in bouts lasting <10 min or ≥10 min duration were not associated differently with outcomes. In models adjusted for total MVPA, each minute accumulated in SB bouts lasting 1-15 min was associated with lower BMI -0.012 kg/m(2), WC -0.029 cm, and OR 0.989 for MS (all p < 0.05), and coefficients for LPA bouts 1-9 min were very similar in separate models adjusted for total MVPA. Minutes accumulated in SB bouts 1-15 min and LPA bouts 1-9 min were correlated, r = 0.62. Objectively measured MVPA, LPA and SB were all associated with lower adiposity and metabolic risk. The beneficial associations of LPA are encouraging for older adults for whom initiating MVPA and maintaining

    Full Text Available Low levels of insulin-like growth factor-1 (IGF-1, an essential neurotrophic factor, have been associated with worse cognitive function in older adults. However, few studies have assessed the prospective association of serum IGF-1 with cognitive function. We aimed to determine the association between serum IGF-1 on concurrent and prospective cognitive function in a population sample of men aged 40-80 years. Blood samples were assessed for IGF-1 levels at baseline and neuropsychological assessments were performed at baseline (n = 400 and at follow-up after a mean duration of 8.3 years (n = 286. Linear regression analyses were carried out to determine the associations between quintiles of IGF-1 and cognitive function at the baseline and follow-up visits. Results showed that those in the top quintile of IGF-1 had lower processing capacity and global cognition scores at follow-up after controlling for cognitive function at baseline and other confounding factors. Additional analyses exploring associations with IGF-1 separately in middle-aged and older participants, and with quartiles of IGF-1 produced similar results. In those older than 60 years, high IGF-1 levels were also associated with lower baseline processing capacity. These results suggest that high IGF-1 levels are associated with worse long-term cognition in men. Together with past studies, we suggest that both, high and low levels of IGF-1 may be associated with poor cognitive function and that optimum levels of IGF-1 (quintile 2 and 3 in current study may be associated with better cognitive function.

  20. Fall risk awareness and safety precautions taken by older community-dwelling women and men--a qualitative study using focus group discussions.

    Petra Pohl

    Full Text Available Daily life requires frequent estimations of the risk of falling and the ability to avoid a fall. The objective of this study was to explore older women's and men's understanding of fall risk and their experiences with safety precautions taken to prevent falls.A qualitative study with focus group discussions was conducted. Eighteen community-dwelling people [10 women and 8 men] with and without a history of falls were purposively recruited. Participants were divided into two groups, and each group met four times. A participatory and appreciative action and reflection approach was used to guide the discussions. All discussions were audio recorded and transcribed verbatim. Data were analysed by qualitative content analysis, and categories were determined inductively.Three categories describing the process of becoming aware of fall risks in everyday life were identified: 1] Facing various feelings, 2] Recognizing one's fall risk, and 3] Taking precautions. Each category comprised several subcategories. The comprehensive theme derived from the categories was "Safety precautions through fall risk awareness". Three strategies of ignoring [continuing a risky activity], gaining insight [realizing the danger in a certain situation], and anticipating [thinking ahead and acting in advance] were related to all choices of actions and could fluctuate in the same person in different contexts.The fall risk awareness process might be initiated for various reasons and can involve different feelings and precautions as well as different strategies. This finding highlights that there are many possible channels to reach older people with information about fall risk and fall prevention, including the media and their peers. The findings offer a deeper understanding of older peoples' conceptualizations about fall risk awareness and make an important contribution to the development and implementation of fall prevention programmes.

    Objectives Men treated with androgen deprivation therapy (ADT) or radiation therapy (RT) for prostate cancer have an increased risk for fractures. Given uncertainty as to whether specific clinical factors can identify men at increased risk, we sought to develop a prognostic index for risk of fracture in this population. Materials and methods We used the Surveillance, Epidemiology, and End Results-Medicare database to identify men who received ADT or RT after being diagnosed with localized prostate cancer in 2007-2009. Cox proportional hazards models tested the association of potential risk factors with fracture. In a derivation group, hazard ratios were used to assign points for factors independently related to fracture. The prognostic index was then applied to a validation group. Results The sample of 5,824 men had a median age of 73.0 years; 82.9% were white and 8.6% had a fracture within 2 years of treatment for prostate cancer. The Cox model identified 8 variables (age, race, hormone treatment, Elixhauser score, anxiety, Parkinson's, fall-inducing medications and disability status) independently associated with fracture. In the derivation cohort, 4.3% of the sample experienced a fracture in the low-risk group, 8.9% in the intermediate group, and 19.2% in the high-risk group (C statistic, 0.749). The index was applied to the validation cohort (C statistic, 0.782). Conclusion The prognostic index can help to identify patients at increased risk for fracture. This underscores the importance of identifying risk factors for fracture, given the substantial variation in fracture risk in men treated with ADT or RT. PMID:25240918

    Osteoporosis is characterized late in the course of the disease by an increased risk of fracture, particularly in the elderly. It occurs in both sexes, affecting approximately 8 million women and 2 million men aged > or = 50 years (1). While low bone density is a predictor of fractures, it is not the only determinant of fracture risk. Other factors include advanced age, altered bone quality, a personal or family history of falls, frailty, poor eyesight, debilitating diseases, and high bone turnover. A diet with sufficient calcium and vitamin D is important to minimize bone loss and, along with regular exercise, to maintain muscle strength. Bisphosphonates have been shown to reduce the risk of hip fracture. For elderly patients, the use of hip protectors may be used as a treatment of last resort. Regardless of the age of the patient, individual patient risk factors must be considered to target appropriate treatment and prevent fracture.

    Vitamin D has been suggested to have a role in various neurovascular diseases, but the data regarding headache is inconclusive. Our aim was to investigate the associations between serum 25-hydroxyvitamin D [25(OH)D], a marker for vitamin D status, and risk of frequent headache. The study population consisted of 2601 men from the population-based Kuopio Ischaemic Heart Disease Risk Factor Study (KIHD) from eastern Finland, aged 42–60 years in 1984–1989. The cross-sectional associations with prevalence of self-reported frequent headache (defined as weekly or daily headaches) were estimated with multivariable-adjusted odds ratios. The average serum 25(OH) concentration was 43.4 nmol/L (SD 18.9, min-max 7.8–136.1 nmol/L). A total of 250 men (9.6%) reported frequent headache. The average serum 25(OH)D concentration among those with frequent headache was 38.3 nmol/L (SD 18.8) and 43.9 nmol/L (SD 18.9) among those without frequent headache, after adjustment for age and year and month of blood draw (P for difference <0.001). After multivariable adjustments, those in the lowest vs. the highest serum 25(OH)D quartile had 113% (95% CI 42, 218%; P for trend <0.001) higher odds for frequent headache. In conclusion, low serum 25(OH)D concentration was associated with markedly higher risk of frequent headache in men. PMID:28045039

    Prospective evaluations of the associations between depressive symptoms and suicide deaths have been mainly performed in high-risk populations, such as individuals with psychiatric disorders or histories of self-harm. The purpose of this study was to prospectively examine whether more severe depressive symptoms assessed using the Geriatric Depression Scale (GDS) were associated with a greater risk of death from suicide in a general-risk population. A total of 113 478 men from the Korean Veterans Health Study (mean age, 58.9 years) who participated in a postal survey in 2004 were followed up for suicide mortality until 2010. Over 6.4 years of follow-up, 400 men died by suicide (56.7 deaths per 100 000 person-years). More severe depressive symptoms were associated with greater risk of suicide death (p for trend depression were 2.18 for mild depression, 2.13 for moderate depression, 3.33 for severe depression, and 3.67 for extreme depression. After adjusting for potential confounders, men with a potential depressive disorder had an approximate 90% higher mortality from suicide (adjusted HR, 1.92; 95% confidence interval [CI], 1.38 to 2.68; pdepression. Each five-point increase in the GDS score was associated with a higher risk of death by suicide (adjusted HR, 1.22; pDepressive symptoms assessed using the GDS were found to be a strong independent predictor of future suicide. However, the estimate of relative risk was weaker than would be expected based on retrospective psychological autopsy studies.

    Resistance exercise is promoted in older adults for its ability to improve muscle mass, strength and, hence, in reducing falls. However, its effects on blood lipids and CVD risk are less well established, particularly in this age group. This study aimed to investigate whether a 1-year resistance exercise program improves lipid profile and chylomicron concentration in older men. Participants were randomised to either three, 1 h resistance training sessions per week (RE) or an active control group [asked to undertake three 30 min walking sessions per week (AC)]. Fasting blood samples were collected at 0, 6, and 12 months for determination of lipid profile and glycaemic control. Diet, morphological and activity data were also collected at these time points. Following 12 months, the RE intervention group had greater improvements in cholesterol profile; LDL-cholesterol concentration significantly decreased by 0.2 (0.2) mM [mean (SEM)] compared to control (P profile promote the implementation of a resistance exercise intervention in this population.

    The aim of the study was to determine whether it is possible to improve both maximum and rapid force production using resistance training that is typically used to induce muscle hypertrophy in previously untrained older men. Subjects (60-72 years) performed 20 weeks of "hypertrophic" resistance training twice weekly (n = 27) or control (n = 11). Maximum dynamic and isometric leg press, as well as isometric force over 0-100 ms, and maximum concentric power tests were performed pre- and post-intervention. Muscle activity was assessed during these tests by surface electromyogram of the vastus lateralis and medialis muscles. Muscle hypertrophy was assessed by panoramic ultrasound of the vastus lateralis. The intervention group increased their maximum isometric (from 2268 ± 544 to 2538 ± 701 N) and dynamic force production (from 137 ± 24 to 165 ± 29 kg), and these changes were significantly different to control (isometric 12 ± 16 vs. 1 ± 9 %; dynamic 21 ± 12 vs. 2 ± 4 %). No within- or between-group differences were observed in rapid isometric force or concentric power. Relative increases in vastus lateralis cross-sectional area trended to be statistically greater in the intervention group (10 ± 8 vs. 3 ± 6 %, P = 0.061). It is recommendable that resistance training programs for older individuals integrate protocols emphasizing maximum force/muscle hypertrophy and rapid force production in order to induce comprehensive health-related and functionally important improvements in this population.

    In a cross-sectional study we investigated the relationship between muscle and bone parameters in the mid-thigh in older people using data from a single axial computed tomographic section through the mid-thigh. Additionally, we studied the association of these variables with incident low-trauma lower limb fractures. A total of 3,762 older individuals (1,838 men and 1,924 women), aged 66-96 years, participants in the AGES-Reykjavik study, were studied. The total cross-sectional muscular area and knee extensor strength declined with age similarly in both sexes. Muscle parameters correlated most strongly with cortical area and total shaft area (adjusted for age, height, and weight) but explained lower limb fractures. Small muscular area, low knee extensor strength, large MA, low cortical thickness, and high BR were significantly associated with fractures in both sexes. Our results show that bone and muscle loss proceed at different rates and with different gender patterns.

    Both restless legs syndrome (RLS) and periodic leg movements in sleep (PLMS) may be associated with incident cardiovascular disease (CVD). However, the individual contributions of these factors to adverse CVD outcomes are unknown. During the MrOS Sleep Study, 2823 men (mean age = 76.3 years) participated in a comprehensive sleep assessment from 2000 to 2002. RLS was identified by self-report of a physician diagnosis of RLS. A periodic limb movement of sleep index (PLMI) was derived from unattended in-home polysomnography. Incident cardiovascular events were centrally adjudicated during 8.7 ± 2.6 years of follow-up. The primary outcome was all-cause CVD; secondary outcomes included incident myocardial infarction (MI) and cerebrovascular disease. Cox proportional hazards regression models were adjusted for multiple covariates, including PLMI, to examine if there were independent associations of RLS and PLMI to the outcomes. Physician-diagnosed RLS was reported by 2.2% and a PLMI ≥ 15 was found in 59.6% of men. RLS was not associated with the composite CVD outcome. RLS was significantly associated with incident MI (Hazard ratio [HR] = 2.02, 95% CI, 1.04-3.91) even after adjustment for multiple covariates. Results were only modestly attenuated when PLMI was added to the model. PLMI also was found to predict incident MI (per SD increase in PLMI, HR = 1.14, 95% CI, 1.00-1.30, p = .05), and was materially unchanged after addition of RLS. The independent risk that RLS confers for MI suggests a role for non-PLMS factors such as sleep disturbance, shared genetic factors, or PLM-independent sympathetic hyperactivity.

    To investigate risk factors associated with low subjective well-being (SWB) in men and women (≥65 years) separately with a special focus on emotional distress. A cross-sectional analysis was conducted among 3602 participants (50.6% women) aged 65-90 years (mean age 72.8 years, SD ± 5.8) from the population-based KORA-Age study conducted in 2008/2009. SWB was assessed using the WHO-5 well-being index (score range: 0 to 100). SWB was dichotomized into "low" (score ≤ 50) and "high" (score > 50) SWB. The association between potential risk factors and SWB was assessed by logistic regressions analyses. Population-attributable risks (PARs) were calculated. Low SWB was significantly higher in women than in men (23.8% versus 18.2%; p < 0.0001). The logistic regressions analyses revealed low income, physical inactivity, multimorbidity, depression, anxiety and sleeping problems to be associated with low SWB in both sexes. Living alone increased the odds of having low SWB in women, but not in men. Depression and anxiety were the strongest risk factors of low SWB among men (depression: OR: 4.19, 95% CI: 1.33-13.17, p < 0.05; anxiety: 8.45, 5.14-13.87, p < 0.0001) and women (depression: 6.83, 2.49-18.75 p < 0.05; anxiety: 7.31, 5.14-10.39, p < 0.0001). In both sexes, anxiety had the highest population-attributable risk (men: 27%, women: 41%). Our results call out for an increased focus on mental health interventions among older adults, especially for women living alone. Further research is needed to understand the paradoxical pattern of discrepant subjective well-being versus objective health in age.

    Ageing is associated with sarcopenia, osteoporosis, and increased fall risk, all of which contribute to increased fracture risk. Mechanically, bone strength adapts in response to forces created by muscle contractions. Adaptations can be through changes in bone size, geometry, and bending strength. Muscle mass is often used as a surrogate for muscle force; however, force can be increased without changes in muscle mass. Increased fall risk with ageing has been associated with a decline in muscle power-which is a measure of mobility. The aims of this study were as follows: (i) to investigate the relationship between muscle parameters in the upper and lower limbs with age in UK men and the influence of ethnicity on these relationships; (ii) to examine the relationships between jump force/grip strength/cross-sectional muscle area (CSMA) with bone outcomes at the radius and tibia. White European, Black Afro-Caribbean, and South Asian men aged 40-79 years were recruited from Manchester, UK. Cortical bone mineral content, cross-sectional area, cortical area, cross-sectional moment of inertia, and CSMA were measured at the diaphysis of the radius and tibia using peripheral quantitative computed tomography. Lower limb jump force and power were measured from a single two-legged jump performed on a ground-reaction force platform. Grip strength was measured using a dynamometer. Associations between muscle and bone outcomes was determined using linear regression with adjustments for age, height, weight, and ethnicity. Three hundred and one men were recruited. Jump force was negatively associated with age; for every 10 year increase in age, there was a 4% reduction in jump force (P power (P = 0.039); after adjustments, this was attenuated (P = 0.088). For every 10 year increase in age, grip strength decreased by 11%. Jump force was positively associated with tibial bone outcomes: a 1 standard deviation greater jump force was associated with significantly higher cortical

    Dehydroepiandrosterone (DHEA) is a steroid that shows a marked age-related decline in humans. Previous research suggests potential for DHEA replacement in old age to enhance cognition and well-being. We conducted a clinical trial to test these hypotheses in a non-clinical sample of 46 men aged 62-76. Participants received either 50 mg DHEA daily for 13 weeks, followed by placebo for 13 weeks, or the reverse, in a randomised double-blind cross-over trial design. Levels of salivary cortisol and DHEA were measured at 0800 h and 2000 h prior to each assessment session. Cognition was assessed with tests of speed, attention and episodic memory. Well-being was measured with questionnaires of mood and perceived health. Mood questionnaires were completed at the assessment session as well as concurrently with saliva sampling.A correlational analysis of baseline behavioural data with hormonal data, controlling for age, revealed that higher morning DHEA was associated with lower confusion (r=-0.33; P=0.04), while higher evening DHEA was associated with lower anxiety (r=-0.35; P=0.03) and lower current negative mood in the morning (r=-0.37; P=0.03). Conversely, higher morning cortisol and a morning cortisol/DHEA ratio were associated with higher anxiety (r=0.35; P=0.03), (r=0.46; P=0.004), general mood disturbance (r=0.32; P=0.046), (r=0.32; P=0.04) and higher current negative mood in the evening (r=0.37; P=0.03), (r=0.38; P=0.03). A higher morning cortisol/DHEA ratio was also associated with higher confusion (r=0.39; P=0.01) and lower visuo-spatial memory performance (r=-0.39; P=0.01). Unexpectedly, higher evening cortisol was associated with faster choice reaction time (r=-0.33; P=0.04). These findings are consistent with an impairing effect of high cortisol on episodic memory and mood in older men, which may be attenuated by DHEA. When treatment effects were analysed, no significant effects of DHEA were observed on any of the trial outcomes, providing no support for benefits

    Myostatin inhibits myoblast proliferation and differentiation in developing muscle. Mounting evidence suggests that myostatin also plays a limiting role in growth/repair/regeneration of differentiated adult muscle by inhibiting satellite cell activation. We tested the hypothesis that myostatin mRNA expression would decrease after resistance loading (RL) with a blunted response in older (O) females (F) who have shown minimal hypertrophy [vs. males (M)] after long-term RL. As myostatin is thought to modulate cell cycle activity, we also studied the response of gene transcripts key to stimulation (cyclin B1 and D1) and inhibition (p21cip and p27kip) of the cell cycle, along with the muscle-specific load-sensitive mitogen mechano-growth factor (MGF). Twenty young (Y; 20-35 yr, 10 YF, 10 YM) and 18 O (60-75 yr, 9 OF, 9 OM) consented to vastus lateralis biopsy before and 24 h after a bout of RL (3 sets x 8-12 repetitions to volitional fatigue of squat, leg press, knee extension). Gene expression levels were determined by relative RT-PCR with 18S as an internal standard and analyzed by age x gender x load repeated-measures ANOVA. A load effect was found for four transcripts (P Y) and an age x gender interaction (66%, OF > YF vs. 10%, OM > YM; P Y) led to a main age effect (P < 0.05). An age x load interaction for cyclin B1 (P < 0.05) was driven by a 26% increase in Y with no change in O after RL. No age or gender differences, or load-mediated changes, were detected in levels of p21cip mRNA expression. These data clearly demonstrate that RL downregulates myostatin expression and alters genes key to cell cycle progression. However, failure to reduce myostatin expression may play a role in limiting RL-induced hypertrophy in OF.

    Full Text Available Background: This cross-sectional study evaluated the association between unhealthy lifestyle behaviors and the prevalence of chronic kidney disease (CKD in middle-aged and older men. Methods: The subjects included 445 men without a history of cardiovascular disease, stroke, or dialysis treatment, who were not taking medications. Unhealthy lifestyle behaviors were evaluated using a standardized selfadministered questionnaire and were defined as follows: 1 lack of habitual moderate exercise, 2 lack of daily physical activity, 3 slow walking speed, 4 fast eating speed, 5 late-night dinner, 6 bedtime snacking, and 7 skipping breakfast. The participants were divided into four categories, which were classified into quartile distributions based on the number of unhealthy lifestyle behaviors (0–1, 2, 3, and ≥4 unhealthy behaviors. Results: According to a multivariate analysis, the odds ratio (OR for CKD (defined as estimated glomerular filtration rate [eGFR] <60 mL/min/1.73 m2 and/or proteinuria was found to be significantly higher in the ≥4 group than in the 0–1 group (OR 4.67; 95% confidence interval [CI], 1.51–14.40. Moreover, subjects’ lack of habitual moderate exercise (OR 3.06; 95% CI, 1.13–8.32 and presence of late-night dinner (OR 2.84; 95% CI, 1.40–5.75 and bedtime snacking behaviors (OR 2.87; 95% CI, 1.27–6.45 were found to be significantly associated with the prevalence of CKD. Conclusions: These results suggest that an accumulation of unhealthy lifestyle behaviors, especially those related to lack of habitual moderate exercise and presence of late-night dinner and bedtime snacking may be associated with the prevalence of CKD.

    Osteoporotic fractures are one of the leading causes of death in the elderly population, but mortality may have been reduced by the advances in management and prevention during recent decades. The authors analyzed the population-level impact of these fractures on mortality in France from 1968 to 2004. About 20 million death certificates registered in metropolitan France from 1968 to 2004 were analyzed. Osteoporotic fractures were identified by using a previously developed methodology. Age-specific and standardized mortality rates were calculated by site of fracture and sex, and time trends were evaluated. Associated causes of death were compared between the extreme periods of the study by the observed/expected pairs method; 440,890 (2.2%) death certificates reported an osteoporotic fracture. Osteoporotic fractures overall, particularly hip and skull fractures, declined by half during the study period, exceeding the decline in general mortality and resulting in fracture-deceased subjects being older. However, pelvis, vertebral, and rib fractures became more frequent. Associated causes of death increased with time, except for decubitus ulcers, indicating a change in the pattern of the death process. Despite a 50% decline, osteoporotic fractures still have a significant impact on mortality. The pattern of the death process has changed, with an increased role for comorbidities.

    Full Text Available Asian-specific prediction models for estimating individual risk of osteoporotic fractures are rare. We developed a Korean fracture risk prediction model using clinical risk factors and assessed validity of the final model.A total of 718,306 Korean men and women aged 50-90 years were followed for 7 years in a national system-based cohort study. In total, 50% of the subjects were assigned randomly to the development dataset and 50% were assigned to the validation dataset. Clinical risk factors for osteoporotic fracture were assessed at the biennial health check. Data on osteoporotic fractures during the follow-up period were identified by ICD-10 codes and the nationwide database of the National Health Insurance Service (NHIS.During the follow-up period, 19,840 osteoporotic fractures were reported (4,889 in men and 14,951 in women in the development dataset. The assessment tool called the Korean Fracture Risk Score (KFRS is comprised of a set of nine variables, including age, body mass index, recent fragility fracture, current smoking, high alcohol intake, lack of regular exercise, recent use of oral glucocorticoid, rheumatoid arthritis, and other causes of secondary osteoporosis. The KFRS predicted osteoporotic fractures over the 7 years. This score was validated using an independent dataset. A close relationship with overall fracture rate was observed when we compared the mean predicted scores after applying the KFRS with the observed risks after 7 years within each 10th of predicted risk.We developed a Korean specific prediction model for osteoporotic fractures. The KFRS was able to predict risk of fracture in the primary population without bone mineral density testing and is therefore suitable for use in both clinical setting and self-assessment.

    We examined the relationship between body composition and changes in plasma carotenoid concentration in response to dietary carotenoid restriction or beta-carotene (betaC) supplementation in healthy older men. Subjects (mean age 65 y) were assigned randomly to supplement (30 mg betaC/d) or placebo groups, and all subjects consumed a standard low carotenoid basal diet plus 1.5 mg betaC/d as carrots. Body composition was measured at baseline by hydrodensitometry, and plasma carotenoids were measured at baseline and after 28 d of treatment by HPLC. Baseline plasma total carotenoid concentration was significantly and negatively correlated with body mass index (BMI) and fat-free mass (FFM) but not with fat mass, whereas baseline betaC concentration was negatively associated with all three variables. The increase in plasma betaC concentration in response to betaC supplementation was significantly and inversely correlated with BMI and FFM but not with fat mass. Likewise, the decline in plasma total carotenoid concentration in the placebo group was also significantly and inversely related to BMI and FFM but not to fat mass. Thus, FFM seems to be an important determinant of plasma carotenoid concentrations and to explain a substantial portion of the often-observed relationship between BMI and blood carotenoid levels. Fat-free mass seems to represent a dynamic reservoir that dampens short-term changes in plasma carotenoid concentrations during fluctuation in carotenoid intake.

    Osteoporosis is prevalent in men with an estimated one in eight men older than 50 years suffering from osteoporotic fracture, and a higher mortality rate after fracture among men compared with women. There are few approved therapies for osteoporosis in men. This observational study assesses the efficacy and safety of risedronate in the treatment of men with primary and secondary osteoporosis. A single-center, open label, randomized, prospective 1-year study was conducted in men with primary or secondary osteoporosis. Patients were randomized to risedronate (risedronate 5 mg/day plus calcium 1,000 mg/day and vitamin D 800 IU/day) or control groups (alfacalcidol 1 mug/day plus calcium 500 mg/day or vitamin D 1,000 IU/day plus calcium 800 mg/day). Bone mineral density (BMD) measurements, X-rays of the spine, a medical history and physical exam, and patient self-assessments of back pain were performed at baseline and 12 months. Blinded semi-quantitative fracture assessment was conducted by a radiologist. A total of 316 men with osteoporosis were enrolled in the trial (risedronate, n=158; control, n=158). At 1 year lumbar spine BMD increased by 4.7% in the risedronate group versus an increase of 1.0% in the control group (P<0.001). Significant increases in BMD at the total hip and femoral neck were also observed with risedronate compared with the control group. The incidence of new vertebral fracture in the risedronate group was reduced by 60% versus the control group (P=0.028). Daily treatment with risedronate for 12 months significantly increased BMD at the lumbar spine, femoral neck and total hip and significantly reduced the incidence of new vertebral fractures. This is the first prospective, randomized, controlled trial to demonstrate a significant reduction in vertebral fractures in 1 year in men with primary or secondary osteoporosis.

    Full Text Available The use of testosterone in older men, known as male hormonal replacement therapy or androgen replacement therapy, has become of increasing interest to both the medical and lay communities over the past decade. Even though the knowledge of the potential benefits and risks of male Androgen Replacement Therapy has increased dramatically, there is still much that needs to be determined. Although there are a number of potential benefits of male Androgen Replacement Therapy and data concerning clinical effects of such replacement have accumulated, as yet there have not been any large multicenter randomized controlled trials of this therapy. It is the purpose of this article to review what is currently known about the possible risks and benefits of male Androgen Replacement Therapy by discussing the clinical trials to date.O uso da testosterona em homens idosos, conhecido como Terapia de Reposição Hormonal no homem ou Terapia de Reposição com Androgênios, têm aumentado o interesse para as comunidades médica e leiga na última década.

    Men on the Move-Nashvillewas a quasi-experimental, 10-week pilot physical activity intervention. A total of 40 overweight or obese African American men ages 30 to 70 (mean age = 47) enrolled in the intervention. Participants attended 8 weekly, 90-minute small group sessions with a certified personal trainer. Each session consisted of discussions aimed to educate and motivate men to be more physically active, and an exercise component aimed to increase endurance, strength, and flexibility. Throughout each week, men used wearable activity trackers to promote self-monitoring and received informational and motivational SMS text messages. Of the 40 enrolled men, 85% completed the intervention, and 80% attended four or more small group sessions. Additionally, 70% of participants successfully used the activity tracker, but only 30% of men utilized their gym memberships. Participants benefited from both the small group discussions and activities through increasing social connection and guidance from their trainer and group members. These African American men reported being motivated to engage in physical activity through each of these technologies. Men reported that the activity trackers provided an important extension to their social network of physically active people. The intervention resulted in significant increases in men's self-reported levels of light, moderate, vigorous, and sports-related physical activities, and high-density lipoprotein cholesterol levels, and significant decreases in weight and body fat percentage with small, moderate and large effects shown. Including technology and didactic components in small group-based interventions holds promise in motivating African American men to increase their physical activity.

    Full Text Available Vertebral fractures are a frequent entity, mainly in the thoracolumbar and lumbar spine. In some circumstances the differential diagnosis of vertebral injuries can confuse the physician, since the difference between an osteoporotic vertebral fracture and a fracture secondary to a tumor is not clear. We report the case of a patient with osteoporotic vertebral fracture simulating a spinal tumor, handled by our department of neurosurgery as illustrative experience to guide the approach in those cases, in which the definitive diagnosis is crucial for therapeutic decision making

    Numerous high quality studies have shown the positive effects of various osteoporotic medical treatment regimens on bone mass and on the reduction of risk for new spinal, hip and non-spinal fractures in osteoporotic patients. However, the effect of osteoporotic treatment on the functional and clinical outcome of patients who have sustained hip fractures and been treated surgically has not yet been addressed. Five hundred and twenty patients out of 611 who were admitted (2009-2011), operated on due to a hip fracture and completed their follow-up evaluations were included in this study. Data related to functional outcome scores, re-fracture rate, quality of life and mortality rate were prospectively recorded, analysed and correlated to osteoporotic medical treatment. There were 151 (25%) men and 369 (71%) women with a mean age of 80.7 years (range, 60 to 90 years). At a mean follow-up of 27.5 months (range, 24 to 36 months) a mortality rate of 23.6% at 2 years was recorded. Mean values of functional and quality of life scores were found to have progressively improved within two years after surgery. Seventy-eight (15%) patients were taking osteoporotic treatment before their hip fracture and 89 (17.1%) started afterwards.

    To investigate the changes in respiratory function of COPD patients with osteoporotic vertebral compression fractures (OVCFs) after kyphoplasty (KP). Pain scores, pulmonary function parameters (PFT), and local kyphotic angle (LKA) were measured in 31 older patients (25 women, 6 men) with OVCFs before, 3 days after and 3 months after kyphoplasty. The preoperative and postoperative (3 days, 3 months) PFT parameters were as follows: % pred FVC, 74.33 ± 12.35, 85.23.8 ± 13.23, and 84.86 ± 14.01; % pred FEV1, 60.23 ± 11.2, 60.02 ± 11.90, and 60.78 ± 12.70; FEV1/FVC ratio (%), 68.22 ± 16.74, 59.56 ± 13.23, and 60.77 ± 12.28, % pred MVV 52.46 ± 14.37, 55.23 ± 15.68, and 62.12 ± 14.48, respectively. The preoperative mean VAS score was 8.01 ± 1.41 and significantly decreased to 2.52 ± 0.89 and 2.34 ± 0.78 at 3 days, 3 months after kyphoplasty, respectively. The preoperative local kyphotic angle degree was 21.96 ± 5.75°, significantly decreased to 13.48 ± 6.12° 3 days after KP, and maintained 3 month after KP. The decrease in the VAS scores correlated with the PFT parameters; however, there were no significant correlations between the PFT parameters and the LKA, the VAS scores and the LKA. Kyphoplasty under local anesthesia is a safety treatment for the COPD patients with OVCFS, and is able to improve the lung function impaired by OVCFs.

    Osteoporotic vertebral compression fractures are common and cause pain and disability. Most osteoporotic vertebral compression fractures occur in the lower thoracic and thoracolumbar spine. Percutaneous balloon kyphoplasty through a transpedicular approach is a classic procedure performed to treat osteoporotic vertebral compression fractures. However, due to the slender morphology of the pedicles, small pedicle size, and the angular severity of thoracic kyphosis, performing kyphoplasty in middle and high thoracic levels is technically challenging. The purpose of this retrospective study was to evaluate the clinical outcomes of single-balloon kyphoplasty for the treatment of thoracic osteoporotic vertebral compression fractures via an extrapedicular approach. Between July 2004 and May 2008, thirty-eight patients with thoracic osteoporotic vertebral compression fractures underwent percutaneous kyphoplasty via a unilateral extrapedicular approach. Average patient age was 60.3 years. Symptomatic levels ranged from T4 to T12. All affected vertebrae were identified via physical examination, magnetic resonance imaging, and radiographs. Pain relief, vertebral height restoration, and kyphosis correction were compared pre- and postoperatively using the visual analog scale and radiographs. The operation was successful in all patients. Average injected bone cement volume was 3.2±1.4 mL. Mean follow-up was 9.5 months. Visual analog scale pain score improved in 36 of 38 patients postoperatively. Mean visual analog scale pain score was 8.92±0.682 preoperatively and 2.40±0.31 postoperatively and remained at 2.80±0.34 until last follow-up. Mean middle body height correction ratio was 50.9%±34.6%. No lateral wedging was found in the coronal alignment of the treated vertebrae. Three (7.9%) patients sustained cement extravasation with no adverse events. Kyphoplasty through a unilateral extrapedicular approach can achieve convergent and proper cement filling in the affected

    Purpose: Osteoporotic vertebral fractures are frequently asymptomatic. They are often not diagnosed clinically or radiologically. Despite this, prevalent osteoporotic vertebral fractures predict future osteoporotic fractures and are associated with increased mortality and morbidity. Appropriate management of osteoporosis can reduce future fracture risk. Fractures on lateral chest radiographs taken for other conditions are frequently overlooked by radiologists. Our aim was to assess the value of computed tomography (CT) in the diagnosis of vertebral fracture and identify the frequency with which significant fractures are missed. Materials and methods: The thoracic CT scans of 100 consecutive male and 100 consecutive female patients over 55 years were reviewed. CT images were acquired on General Electric Lightspeed multi-detector (MD) CT scanners (16 or 32 row) using 1.25 mm slice thickness. Midline sagittal images were reconstructed from the 3D volume images. The presence of moderate (25-40% height loss) or severe (>40% height loss) vertebral fractures between T1 and L1 was determined using an established semi-quantitative method and confirmed by morphological measurement. Results were compared with the formal CT report. Results: Scans of 192 patients were analysed (95 female; 97 male); mean age 70.1 years. Thirty-eight (19.8%) patients had one or more moderate to severe vertebral fractures. Only 5 (13%) were correctly reported as having osteoporotic fractures in the official report. The sensitivity of axial CT images to vertebral fracture was 0.35. Conclusion: Incidental osteoporotic vertebral fractures are under-reported on CT. The sensitivity of axial images in detecting these fractures is poor. Sagittal reformations are strongly recommended to improve the detection rate.

    Full Text Available Abstract Background Today, while there are effective drugs that reduce the risk of osteoporotic fracture, yet there are no broadly accepted criteria that can be used to estimate risks and decide who should receive treatment. One of the actual priorities of clinical research is to develop a set of simple and readily-available clinical data that can be used in routine clinical practice to identify patients at high risk of bone fracture, and to establish thresholds for therapeutic interventions. Such a tool would have high impact on healthcare policies. The main objective of the ESOSVAL-R is to develop a risk prediction scale of osteoporotic fracture in adult population using data from the Region of Valencia, Spain. Methods/Design Study design: An observational, longitudinal, prospective cohort study, undertaken in the Region of Valencia, with an initial follow-up period of five years; Subjects: 14,500 men and women over the age of 50, residing in the Region and receiving healthcare from centers where the ABUCASIS electronic clinical records system is implanted; Sources of data: The ABUCASIS electronic clinical record system, complemented with hospital morbidity registers, hospital Accidents & Emergency records and the Regional Ministry of Health's mortality register; Measurement of results: Incident osteoporotic fracture (in the hip and/or major osteoporotic fracture during the study's follow-up period. Independent variables include clinical data and complementary examinations; Analysis: 1 Descriptive analysis of the cohorts' baseline data; 2 Upon completion of the follow-up period, analysis of the strength of association between the risk factors and the incidence of osteoporotic fracture using Cox's proportional hazards model; 3 Development and validation of a model to predict risk of osteoporotic fracture; the validated model will serve to develop a simplified scale that can be used during routine clinical visits.

    Background Depressive symptoms are common in older adults and associated with poor outcomes. While circadian genes have been implicated in depression, the relationship between circadian genes and depressive symptoms in older adults is unclear. Methods A cross-sectional genetic association study of 529 single nucleotide polymorphisms (SNPs) representing 30 candidate circadian genes was performed in two population-based cohorts: Osteoporotic Fractures in Men Study (MrOS, n=1270, age 76.58±5.61 years) and the Study of Osteoporotic Fractures (SOF) in women (n=1740, 84.05±3.53 years) and a meta-analysis was performed. Depressive symptoms were assessed with the Geriatric Depression Scale categorizing participants as having “none-few symptoms” (0-2), “some depressive symptoms” (>2<6), or “many depressive symptoms” (≥6). Results We found associations meeting multiple testing criteria for significance between the PER3 intronic SNP rs12137927 and decreased odds of reporting “some depressive symptoms” in the SOF sample (OR 0.61, CI 0.48-0.78, df=1, Wald chi-square −4.04, p=0.000054) and the meta-analysis (OR 0.61, CI 0.48-0.78, z= −4.04, p=0.000054) and between the PER3 intronic SNPs rs228644 (OR 0.74, CI 0.63-0.86, z= 3.82, p-value=0.00013) and rs228682 (OR 0.74, CI 0.86 0.63, z= 3.81, p-value=0.00014) and decreased odds of reporting “some depressive symptoms” in the meta-analysis compared to endorsing none-few depressive symptoms. The RORA intronic SNP rs11632098 was associated with greater odds of reporting “many depressive symptoms” (OR 2.16, CI 1.45-3.23, df=1, Wald chi-square 3.76, p=0.000168) in the men. In the meta analysis the association was attenuated and nominally significant (OR 1.63, CI 1.24-2.16, z=3.45, p=0.00056). Conclusions PER3 and RORA may play important roles in the development of depressive symptoms in older adults. PMID:25892098

    Data on the association between dietary vitamin K intake and fracture risk are limited among Chinese. This study examined such an association in community-dwelling elderly in Hong Kong. We present data from 2,944 subjects (1,605 men, 1,339 women) who participated in a prospective cohort study. Baseline dietary intakes of energy, protein, calcium, vitamin D, and vitamin K were assessed using a food-frequency questionnaire. Data on incident hip fracture and nonvertebral fracture during a median of 6.9 follow-up years were collected from a hospital database. Cox regression analyses were performed with adjustments for age, education attainment, smoking status, alcohol use, body mass index, hip bone mineral density, physical activity, use of calcium supplement, and energy-adjusted nutrient intakes. There were 29 (1.8 %) men and 19 (1.4 %) women with incident hip fractures and 97 (6.0 %) men and 88 (6.6 %) women with nonvertebral fractures. The median (interquartile range) of dietary vitamin K intake was 241.8 (157.5-360.8) and 238.9 (162.4-343.6) μg/day in men and women, respectively. Similar dietary vitamin K intakes were observed between subjects with hip or nonvertebral fractures and subjects without hip or nonvertebral fractures. In both men and women, dietary vitamin K intake was not associated with fracture risks at all measured sites in either crude or adjusted models. In Chinese community-dwelling elderly, hip or nonvertebral fracture risk was not associated with dietary vitamin K intake. The high dietary vitamin K intake of the studied group may have limited the ability to detect the association between vitamin K intake and fracture risk.

    Objective: To explore the effect of percutaneous vertebroplasty to treat osteoporotic vertebral body compression fractures. Methods: Seventeen patients with compression fractures at 27 different levels came in for percutaneous vertebroplasty. Under the guidance of C-arm image intensifier, bone needle was inserted into the fracture vertebral bodies via a unilateral transpedicular approach.Polymethyl methacrylate (PMMA) was injected slowly under continuous fluoroscopic control. Then the effect was evaluated after operation.Results: Follow-up results among 15 patients were studied, other two patients lost contact. The follow-up period was from three to seven months. No patient had relapse of compression fracture. Leakage of the cement outside the vertebral body was seen in four bodies. All patients had a complete relief after Percutaneous vertebroplasty(PVP). Conclusion: PVP is an efficient minimally invasive technique to treat osteoporotic vertebral body compression fractures.

  8. [From the Cochrane Library: ultrasonographic screening for abdominal aortic aneurysm in men aged 65 years and older: low risk of fatal aneurysm rupture].

    2008-03-29

    Abdominal aortic aneurysm (AAA) is present in 5-10% of men aged 65-79 years and is often asymptomatic. The major complication is rupture, which requires emergency surgery. The mortality rate after rupture is high: about 80% of those who reach the hospital and 50% of those undergoing emergency surgery will die. Elective surgical repair of AAA aims to prevent death from rupture; the 30-day surgical mortality rate for open surgery is approximately 5%. Currently elective surgical repair is recommended for aneurysms larger than 5-5 cm to prevent rupture. There is interest in population screening to detect, monitor and repair AAA before rupture. A Cochrane systematic review of 4 randomised studies involving 127,891 men and 9,342 women revealed a significant reduction in mortality from AAA in men aged 65-79 years who underwent ultrasonographic screening (odds ratio (OR): 0.60; 95% CI: 0.47-0.78). There was insufficient evidence to demonstrate a benefit in women. Men who had been screened underwent more surgery for AAA (OR: 2.03; 95% CI: 1.59-2.59). These findings should be considered carefully when determining whether a coordinated population-based screening programme should be introduced. A gap in the current research is the balance of benefits and risks in women. Furthermore, detailed studies are needed on how to best provide information on the potential benefits and risks to individuals who are offered screening, and on the psychological effects of screening on patients and their partners.

    Spinal osteoarthritis has been suggested as a risk factor for vertebral fractures. However, results are conflicting: most of the data are focused on the lumbar region, and referred to postmenopausal women, whereas data for men are scarce. The aim of this study is to assess the relationship between spinal osteoarthritis and vertebral fractures in men over 50 years of age. We conducted a cross-sectional study, nested in a prospective population-based cohort, including 507 community-dwelling men, 93 of them with at least one vertebral fracture. Vertebral fractures, osteophytosis, and disc space narrowing (DSN) were assessed by lateral thoracic and lumbar radiographs. Anthropometric, clinical, and densitometric variables were also analyzed. A multiple logistic regression model was performed. Eighty-five percent of vertebral fractures were located at the thoracic spine. Osteophytosis and DSN showed a bimodal distribution, with major frequency peaks at mid- and distal lumbar spine. The three distributions overlapped around the T9 vertebra. We did not find any relationship between lumbar osteoarthritis and vertebral fractures. Nevertheless, thoracic osteophytosis (OR, 1.84; 95 % CI, 1.05-3.17; p = 0.03) and DSN (OR, 2.52; 95 % CI, 1.43-4.46; p = 0.001) were found to be independently associated with prevalent vertebral fractures, after adjusting for confounders. Our results suggest a positive relationship between radiologic osteoarthritic changes at the thoracic spine and prevalent vertebral fractures in men more than 50 years of age. Osteoarthritis may act as a local risk factor, in addition to other mechanical factors, resulting in a greater propensity to fracture, especially at the mid-thoracic region.

    Depression is a common geriatric psychiatric disorder increasing with age among elderly people (≥ 75 years old), especially those with medical comorbidities. They have higher suicide rates than younger men, but these are paid less attention. Elderly men (n=141) who were newly admitted residents of the Veterans' Home in Tainan, Taiwan from 2004 to 2006 were recruited and screened for major depression. Specialist physicians obtained past histories of medical illnesses through chart reviews, interview, and health examinations. Fifty-nine of the 141 elderly people had major depression and participated in this study. Thirty-nine men in the group with vascular comorbidities (VC), and 20 in the group without (NVC) vascular comorbidities were compared. The VC group had more time-orientation impairment, greater psychomotor retardation, and diminished concentration/decision-making than did the NVC group. Psychomotor retardation and other cognitive function impairments (e.g., concentration and decision-making) are characteristic manifestations among patients with major depression and vascular comorbidity compared with those without vascular comorbidity.

    Full Text Available We have recently developed image processing techniques for measuring the cortical thicknesses of skeletal structures in vivo, with resolution surpassing that of the underlying computed tomography system. The resulting thickness maps can be analysed across cohorts by statistical parametric mapping. Applying these methods to the proximal femurs of osteoporotic women, we discover targeted and apparently synergistic effects of pharmaceutical osteoporosis therapy and habitual mechanical load in enhancing bone thickness.

    We report a case of an 81-year-old osteoporotic woman, who suffered stress fractures of the distal fibula on both sides within a two-year period. The risk factors for stress fractures are reviewed and the importance of a high index of suspicion for stress fractures is emphasized. When a stress fracture is suspected it should lead to plain radiography and treatment with protected weight-bearing with crutches or a brace.

  15. Proximal femoral bone geometry in osteoporotic hip fractures in Thailand.

    Science.gov (United States)

    2015-01-01

    A number of different bone geometries have been reported to be correlated with osteoporosis, bone mineral density and fractures. Those correlations are used for diagnosis, treatment and prediction of fracture risk in osteoporosis cases. However there have been no studies of significant bone parameters predicting osteoporosis and hip fracture in Thailand To evaluate the correlation between geometric parameters of the proximal femur and both the Singh index and bone mineral density as well as to investigate the relationship between those two metrics and osteoporotic hip fracture in the Thai population. Forty-four Thai patients with osteoporotic hip fractures andforty-five healthy Thai people matched for age and gender were included in the present study. Bone mineral density and bone geometry from plain hip radiographs of non-fracture sites in the fracture group and proximal femur radiographs of the same site in the healthy group were measured That data were analyzed to determine levels of correlation. Bone geometries were also analyzed to determine hip fracture predictive capacity. Correlation between the Singh index and bone mineral density was significant (p hip fracture (p = 0.014 and p = 0.035, respectively). Each 1 mm reduction in the width of the femoral medial neck cortex increased the osteoporotic hip fracture risk by a factor of 2.7 (OR = 0.37, 95% CI = 0.15-0.93). In the Thai population, bone geometry from plain radiographs can help predict the risk of osteoporotic hip fracture. Osteoporosis is correlated with a low Singh index value. The width of the femoral medial neck cortex is a reliable predictor of hip fracture risk.

    The burden of invasive meningococcal disease is substantial in older adults in whom the case fatality rate is high. Travelers to regions with high rates of meningococcal disease, such as Hajj pilgrims, are at increased risk of meningococcal infection, and disease transmission from travelers to their close contacts has been documented. In younger individuals, meningococcal conjugate vaccines offer advantages over polysaccharide vaccines in terms of duration of protection and boostability, and induction of herd immune effects through reductions in nasopharyngeal carriage of meningococci. To date, few data are available evaluating meningococcal conjugate vaccine use in adults >55 years of age. To evaluate the immunogenicity and safety of quadrivalent meningococcal serogroups A, C, W-135 and Y vaccine with all serogroups conjugated to tetanus toxoid (MenACWY-TT, Nimenrix™, GlaxoSmithKline, Belgium) and a licensed quadrivalent polysaccharide vaccine (MenPS, Mencevax™ GlaxoSmithKline, Belgium) in adults >55 years of age. This was a phase IIIb, open-label, randomized (3:1), controlled study conducted at one study center in Lebanon. A total of 400 healthy adults between 56 and 103 years of age without previous MenPS or tetanus toxoid vaccination within the previous 5 years or meningococcal conjugate vaccination at any time previously were included. They received a single-dose vaccination with MenACWY-TT or MenPS with blood sampling before and 1 month after vaccination. The main outcome measures were serum bactericidal activity (rabbit complement source: rSBA) vaccine response (VR) rate [rSBA titer of ≥1:32 in initially seronegative subjects (rSBA titer <1:8); ≥4-fold increase in subjects with pre-vaccination rSBA titers between 1:8 and 1:128, and ≥2-fold increase in subjects with pre-vaccination rSBA titers ≥1:128]. The percentages of subjects with rSBA titers ≥1:8 and ≥1:128 and rSBA geometric mean titers (GMTs) were assessed. Solicited adverse events

    Full Text Available In elderly people, anemia occurs with increasing frequency with each advancing decade and can be a harbinger of very serious health conditions, including gastrointestinal bleeding, gastric and duodenal ulcers, and cancer. Therefore, age-dependant changes in hematological parameters deserve special attention. Nonetheless, very few longitudinal studies of aging have focused on possible associations between basic anthropometric characteristics and hematological parameters in older people. Here, we present some evidence that body size can be associated with red blood cell count as well as some other selected hematological parameters in adults aged 45 to 70 years. Longitudinal data on anthropometric and hematological parameters have been obtained from physically healthy residents at the Regional Psychiatric Hospital for People with Mental Disorders in Cibórz, Lubuskie Province, Poland (142 individuals, including 68 men and 74 women. The residents who took psychoactive drugs were excluded from the study. To evaluate the studied relationships, three anthropometric traits were used and three dichotomous divisions of the study sample were made. The medians of body height, body weight, and body mass index at the age of 45 years were used to divide the sample into: shorter and taller, lighter and heavier, and slimmer and stouter individuals, respectively. Student’s t-test, Pearson’s correlation, and regression analysis were employed. The results of the present study suggest that the relationship between body size and red blood cell count is slightly more pronounced in men and its strength depends on age. However, the correlations between body size and red blood cell count proved to be weak in both sexes. With aging, the strength of the relation decreased gradually, which might have been caused by the aging-associated changes in the hematopoietic system, anemia, or was an artifact. Further studies are needed to elucidate the unclear association between

    Full Text Available Abstract Background Previous research has shown that underlying dietary patterns are related to the risk of many different adverse health outcomes, but the relationship of these underlying patterns to skeletal fragility is not well understood. The objective of the study was to determine whether dietary patterns in men (ages 25-49, 50+ and women (pre-menopause, post-menopause are related to femoral neck bone mineral density (BMD independently of other lifestyle variables, and whether this relationship is mediated by body mass index. Methods We performed an analysis of 1928 men and 4611 women participants in the Canadian Multicentre Osteoporosis Study, a randomly selected population-based longitudinal cohort. We determined dietary patterns based on the self-administered food frequency questionnaires in year 2 of the study (1997-99. Our primary outcome was BMD as measured by dual x-ray absorptiometry in year 5 of the study (2000-02. Results We identified two underlying dietary patterns using factor analysis and then derived factor scores. The first factor (nutrient dense was most strongly associated with intake of fruits, vegetables, and whole grains. The second factor (energy dense was most strongly associated with intake of soft drinks, potato chips and French fries, certain meats (hamburger, hot dog, lunch meat, bacon, and sausage, and certain desserts (doughnuts, chocolate, ice cream. The energy dense factor was associated with higher body mass index independent of other demographic and lifestyle factors, and body mass index was a strong independent predictor of BMD. Surprisingly, we did not find a similar positive association between diet and BMD. In fact, when adjusted for body mass index, each standard deviation increase in the energy dense score was associated with a BMD decrease of 0.009 (95% CI: 0.002, 0.016 g/cm2 for men 50+ years old and 0.004 (95% CI: 0.000, 0.008 g/cm2 for postmenopausal women. In contrast, for men 25-49 years old

    Full Text Available Objectives. This study collected and evaluated data on the costs of outpatient medical care and family burden associated with osteoporosis-related fracture rehabilitation following hospital discharge in China. Materials and Methods. Data were collected using a patient questionnaire from osteoporosis-related fracture patients (N = 123 who aged 50 years and older who were discharged between January 2011 and January 2013 from 3 large hospitals in China. The survey captured posthospital discharge direct medical costs, indirect medical costs, lost work time for caregivers, and patient ambulatory status. Results. Hip fracture was the most frequent fracture site (62.6%, followed by vertebral fracture (34.2%. The mean direct medical care costs per patient totaled 3,910¥, while mean indirect medical costs totaled 743¥. Lost work time for unpaid family caregivers was 16.4 days, resulting in an average lost income of 3,233¥. The average posthospital direct medical cost, indirect medical cost, and caregiver lost income associated with a fracture patient totaled 7,886¥. Patients’ ambulatory status was negatively impacted following fracture. Conclusions. Significant time and cost of care are placed on patients and caregivers during rehabilitation after discharge for osteoporotic fracture. It is important to evaluate the role and responsibility for creating the growing and inequitable burden placed on patients and caregivers following osteoporotic fracture.

    The mechanism whereby poor intrauterine growth increases risk of adult hip fracture is unclear. We report the association between birth weight and proximal femoral geometry and density in community-dwelling elderly men. We used self-reported birth weight, measured adult height and weight and proximal femoral quantitative computed tomography (QCT) measurements of femoral neck axis length, cross-sectional area, and volumetric BMD (vBMD) among the participants in the Osteoporotic Fractures in Men (MrOS), a cohort study of community-dwelling US men aged 65 and older. We compared men with birth weight <7 pounds (lower birth weight [LBW]; n = 501) and ≥ 9 pounds (higher birth weight [HBW]; n = 262) with those weighing 7-8.9 pounds (medium birth weight [MBW], referent group; n = 1068) using linear regression adjusting for current age, height, and BMI. The mean age of the 1831 men who had both birth weight and QCT measurements was 73 years (SD 5.9). Compared with the referent MBW, HBW men had concordantly longer femoral neck (+0.16 SD; p = .028) and cross-sectional area (+0.24 SD, p = .001). LBW men had a smaller cross-sectional (-0.26 SD, p < .001) but longer femoral neck for their height (+0.11 SD, p = .05). Neither cortical nor trabecular vBMD at the femoral neck was associated with birth weight. These findings support the hypothesis that the skeletal envelope, but not density, is set, in part, at birth. Further research exploring the association between early developmental factors and lifetime fracture risk is needed and may inform primary preventative strategies for fracture prevention.

    This study investigated the effect of Pilates exercise on physical fall risk factors 12 months after an initial 5-week Pilates intervention. The authors hypothesized that ongoing Pilates participation would have a positive effect on physical fall risk factors in those who continued with Pilates exercise compared with those who ceased. Thirty older ambulatory adults (M = 69 years, SD = 7) participated in Pilates classes for 5 weeks with testing preintevention (Time 1 [T1]) and postintervention (Time 2 [T2]) and 12 months later (Time 3 [T3]). Balance and leg strength were compared using a 2-way analysis of variance with repeated measures. Postural sway, dynamic balance, and function improvements evident after the initial Pilates training (T1-T2) were maintained at T3 (p Pilates (n = 14) and those who had ceased. Balance improvements after a short Pilates intervention were maintained 1 year later in all participants, with increased benefits from ongoing participation.

    The adjustment of pulmonary oxygen uptake (VO2p), heart rate (HR), limb blood flow (LBF), and muscle deoxygenation [HHb] was examined during the transition to moderate-intensity, knee-extension exercise in six older adults (70 ± 4 years) under two conditions: normoxia (FIO₂ = 20.9 %) and hypoxia (FIO₂ = 15 %). The subjects performed repeated step transitions from an active baseline (3 W) to an absolute work rate (21 W) in both conditions. Phase 2 VO₂p, HR, LBF, and [HHb] data were fit with an exponential model. Under hypoxic conditions, no change was observed in HR kinetics, on the other hand, LBF kinetics was faster (normoxia 34 ± 3 s; hypoxia 28 ± 2), whereas the overall [HHb] adjustment (τ' = TD + τ) was slower (normoxia 28 ± 2; hypoxia 33 ± 4 s). Phase 2 VO₂p kinetics were unchanged (p < 0.05). The faster LBF kinetics and slower [HHb] kinetics reflect an improved matching between O₂ delivery and O₂ utilization at the microvascular level, preventing the phase 2 VO₂p kinetics from become slower in hypoxia. Moreover, the absolute blood flow values were higher in hypoxia (1.17 ± 0.2 L min(-1)) compared to normoxia (0.96 ± 0.2 L min(-1)) during the steady-state exercise at 21 W. These findings support the idea that, for older adults exercising at a low work rate, an increase of limb blood flow offsets the drop in arterial oxygen content (CaO₂) caused by breathing an hypoxic mixture.

    Concern about the carcinogenic potential of aspartame was raised after an increase in lymphomas and leukemia was reported in an animal study at doses similar to human exposure. Two prospective cohort studies published after the report found inconsistent results for estimated aspartame intake, artificially sweetened beverage consumption, and risk of lymphoid neoplasms. The objective of this study was to examine associations of artificially and sugar-sweetened carbonated beverage consumption (for comparison) and aspartame intake with risk of non-Hodgkin lymphoma (NHL) overall and by major histologic subtype in the Cancer Prevention Study-II Nutrition Cohort. Among 100,442 adult men and women who provided information on diet and lifestyle factors in 1999, 1196 NHL cases were verified during a 10-y follow-up period. Cox proportional hazards regression was used to estimate multivariable-adjusted RRs and 95% CIs. In women and men combined, there were no associations of consumption of ≥1 (355 mL) servings/d of artificially (RR: 0.92; 95% CI: 0.73, 1.17; P-trend: 0.14) or sugar- (RR: 1.10; 95% CI: 0.77, 1.58; P-trend: 0.62) sweetened carbonated beverages with NHL risk, compared to no consumption (P-heterogeneity by gender: 0.11-1.00). Similarly, aspartame intake was not associated with NHL risk (RR: 1.02; 95% CI: 0.84, 1.24; P-trend: 0.69, top vs. bottom quintile). Associations with NHL subtype (multiple myeloma, diffuse large B-cell lymphoma, chronic lymphocytic leukemia/small lymphocytic lymphoma, and follicular and other B-cell lymphoma) were generally null. These findings do not support associations of daily consumption of artificially or sugar-sweetened carbonated beverages, or aspartame, with NHL risk. © 2014 American Society for Nutrition.

    2013-02-01

    Full Text Available Introduction: It has been shown that dyslipidemia is related to bone mineral density and fragility. Hypolipemiant drugs as statins or fibrates seem to increase the bone mineral density and probably to protect against fractures. The question that arises in this context is whether statins or fibrates have a positive effect on bone fracture repair process and which is their behaviour in an osteoporotic context. Our objective was to study the incidence of osteoporosis, dyslipidemia and of the association of these diseases, and to compare the effect of statins and fibrates on fracture repair in experimental conditions.

    Fish rich in n-3 polyunsaturated fatty acids have been suggested to have a favorable effect on bone health, but previous epidemiologic studies have shown inconsistent results. The purpose of the present study was to investigate the hypothesis that the consumption of fish and shellfish is positively associated with bone mass and negatively associated with the risk of osteoporosis in Koreans and Americans. Men and postmenopausal women ≥ 50 years old from the Korean National Health and Nutrition Examination Survey 2008-2011 (n = 7154) and the National Health and Nutrition Examination Survey 2007-2010 (n = 2658) were included. There was a positive correlation between the consumption of fish and shellfish and bone mineral density (BMD) of the total femur, femoral neck, and lumbar spine in Koreans. Consistently, multivariate logistic regression analysis showed a significant association between intake of fish and shellfish and the risk of osteoporosis in Koreans but not in Americans. Consumption of fish and shellfish was 4-5 times higher in Koreans than Americans in the present study. In conclusion, intake of fish and shellfish was associated with BMD and the risk of osteoporosis in Koreans but not in Americans, suggesting that a minimum intake level of fish and shellfish might be recommended to protect against bone loss and osteoporosis.

    Health lifestyles are collective patterns of health risk behaviour that develop within a social habitus. An important area for research is the extent to which health lifestyles become more individualised over time and as people age, or whether health lifestyles remain socially structured. This article presents findings from a Multiple Correspondence Analysis of the British Regional Heart Study. Our findings suggest that smoking and alcohol use retain a strong class patterning as men age (suggesting some support for the long-term importance of social structures in old age). This indicates that, in later life, some forms of class-related health lifestyles become fixed or 'locked in'. In contrast there is evidence to suggest that, for exercise, class becomes less important as people age (suggesting either some support for growing individualisation and or important ageing effects). Further studies are required to examine different forms of health lifestyle in later life in relation to forms of cultural and economic capital. This study provides evidence in support of attempts to theorise health lifestyles in terms of collectivities. Furthermore, the concept of selective lifestyle 'lock-in' may be a useful way of understanding the relationship between class and health lifestyles in old age. © 2010 The Authors.

    Very low energy diets (VLED) are efficacious in inducing rapid weight loss but may not contain adequate macronutrients or micronutrients for individuals with varying nutritional requirements. Adequate protein intake during weight loss appears particularly important to help preserve fat free mass and control appetite, and low energy and carbohydrate content also contributes to appetite control. Therefore, the purpose of this study was to compare the nutritional content (with a focus on protein), nutritional adequacy and cost of all commercially-available VLED brands in Australia. Nutritional content and cost were extracted and compared between brands and to the Recommended Dietary Intake (RDI) or adequate intake (AI) of macronutrients and micronutrients for men and women aged 19-70 years or >70 years. There was wide variability in the nutritional content, nutritional adequacy and cost of VLED brands. Most notably, even brands with the highest daily protein content, based on consuming three products/day (KicStart™ and Optislim(®), ~60 g/day), only met estimated protein requirements of the smallest and youngest women for whom a VLED would be indicated. Considering multiple options to optimise protein content, we propose that adding pure powdered protein is the most suitable option because it minimizes additional energy, carbohydrate and cost of VLEDs.

    Full Text Available This study was designed to compare screw stabilities augmented with different volumes of PMMA and analyze relationship between screw stability and volume of PMMA and optimum volume of PMMA in different bone condition. Osteoporotic and severely osteoporotic synthetic bone blocks were divided into groups A0-A5 and B0-B5, respectively. Different volumes of PMMA were injected in groups A0 to A5 and B0 to B5. Axial pullout tests were performed and Fmax was measured. Fmax in groups A1-A5 were all significantly higher than group A0. Except between groups A1 and A2, A3 and A4, and A4 and A5, there were significant differences on Fmax between any other two groups. Fmax in groups B1-B5 were all significantly higher than group B0. Except between groups B1 and B2, B2 and B3, and B4 and B5, there were significant differences on Fmax between any other two groups. There was significantly positive correlation between Fmax and volume of PMMA in osteoporotic and severely osteoporotic blocks. PMMA can significantly enhance pedicle screw stability in osteoporosis and severe osteoporosis. There were positive correlations between screw stability and volume of PMMA. In this study, injection of 3 mL and 4 mL PMMA was preferred in osteoporotic and severely osteoporotic blocks, respectively.

    Materials and Methods: Twenty six patients (65 years of age or older with the single spine fractures included in study. The preoperative bone mineral density was measured by dual-energy X-ray. The PKP was done in all the cases. Decompression was done if neurological symptoms were present. Results: The results demonstrated osteoporosis with BMD T value ≤ −2.5; injured posterior vertebral body (3 cases had shown the whole damage accompanied by neurological symptoms through X-ray or CT. After 2 days, the remaining patients of back pain symptoms were relieved or disappeared except for three cases of patients with decompression incision. VAS score and Cobb angle changed from preoperative 8.23 ± 0.17 and 28.7 ± 0.33° respectively to postoperative 3.77 ± 0.44 and 3.8 ± 0.2° respectively. Conclusion: Treatment of rupture of the posterior vertebral osteoporotic thoracolumbar fractures by means of kyphoplasty combined with posterior screw-rod system is a safe, effective procedure.

The compromised bone quality caused by this disease represents an important challenge when a surgical procedure (e.g., spinal fusion is needed after failure of conservative treatments. Different pedicle screw designs and instrumentation techniques have been explored to enhance spinal device fixation in bone of compromised quality. These include alterations of screw thread design, optimization of pilot hole size for non-self-tapping screws, modification of the implant’s trajectory, and bone cement augmentation. While the true benefits and limitations of any procedure may not be realized until they are observed in a clinical setting, axial pullout tests, due in large part to their reproducibility and ease of execution, are commonly used to estimate the device’s effectiveness by quantifying the change in force required to remove the screw from the body. The objective of this investigation is to provide an overview of the different pedicle screw designs and the associated surgical techniques either currently utilized or proposed to improve pullout strength in osteoporotic patients.

    Higher dietary net acid loads have been associated with increased bone resorption, reduced bone mineral density (BMD), and increased fracture risk. The objective was to compare bicarbonate (HCO3) measured in arterialized venous blood samples to skeletal outcomes. Arterialized venous samples collected from participants in the Health, Aging and Body Composition (Health ABC) Study were compared to BMD and rate of bone loss. The setting was a community-based observational cohort. A total of 2287 men and women age 74 ± 3 years participated. Arterialized venous blood was obtained at the year 3 study visit and analyzed for pH and pCO2. HCO3 was determined using the Henderson-Hasselbalch equation. BMD was measured at the hip by dual-energy x-ray absorptiometry at the year 1 (baseline) and year 3 study visits. Plasma HCO3 was positively associated with BMD at both year 1 (P = .001) and year 3 (P = .001) in models adjusted for age, race, sex, clinic site, smoking, weight, and estimated glomerular filtration rate. Plasma HCO3 was inversely associated with rate of bone loss at the total hip over the 2.1 ± 0.3 (mean ± SD) years between the two bone density measurements (P acid-base status is an important determinant of skeletal health during aging. Ongoing bone loss was linearly related to arterialized HCO3, even after adjustment for age and renal function. Further research in this area may have major public health implications because reducing dietary net acid load is possible through dietary intervention or through supplementation with alkaline potassium compounds.

    2013-01-01

    Full Text Available Osteoporotic hip fractures are a major cause of morbidity and mortality in the elderly. Furthermore, reduced implant anchorage in osteoporotic bone predisposes towards fixation failure and with an ageing population, even low failure rates represent a significant challenge to healthcare systems. Fixation failure in fragility fractures of the hip ranges from 5% in peritrochanteric fractures through to 15% and 41% in undisplaced and displaced fractures of the femoral neck, respectively. Our findings, in general, support the view that failed internal fixation of these fragility fractures carries a poor prognosis: it leads to a twofold increase in the length of hospital stay and a doubling of healthcare costs. Patients are more likely to suffer a downgrade in their residential status upon discharge with a consequent increase in social dependency. Furthermore, the marked disability and reduction in quality of life evident before salvage procedures may persist at long-term followup. The risk, of course, for the elderly patient with a prolonged period of decreased functioning is that the disability becomes permanent. Despite this, however, no clear link between revision surgery and an increase in mortality has been demonstrated in the literature.

    Full Text Available Objective: Since osteoporosis is a preventable disease to some extent, risk factor determination and if possible modification is very important. The aim of this study is to identify the relationship between ostoporotic risk factors and bone mineral density results and emphasize the importance of risk factors. Materials and Methods: The study comprised 103 postmenopausal osteoporotic women. Demographic characteristics, osteoporortic risk factors, lumbar vertebrae and femur neck T scores were recorded. Relationships between lumbar vertebra and femur neck T scores and risk factors were statistically studied. Results: Advanced age, low physical activity status, inadequte dietary calcium intake and vertebral compression fractures were found to be associated with low bone mineral density results in postmenopausal osteoporotic women whereas marital status, occupation, education level and familial fracture history were not. Furthermore early menopause was found to be associated with low femoral T scores and smoking with low lumbar T scores. Tendency to fall and number of chronic diseases were irrelevant to bone mineral density. Conclusions: Risk factor assesment is still important for osteoporosis prevention.

    Osteoporosis is the most common bone disease. Due to an increase of the older population an higher impact of osteoporosis and its treatment can be expected. Painful osteoporotic vertebral fractures result in an increased morbidity and mortality. Standard treatment of painful osteoporotic vertebral fractures comprises analgetics, bed rest and, if needed, orthotics. By mere augmentation of the vertebra with polymethylmet acrylate (PMMA), the so called ''vertebroplasty'' a good pain reduction and increase in function and quality of life can be achieved. With the technique of kyphoplasty (Kyphon trademark) it is feasable to correct a kyphotic deformity. Inflatable ballons are introduced to the vertebra to lift the endplates. The created cavity is filled with bone cement (PMMA). Kyphoplasty is able to correct osteoporosis induced kyphotic deformity. Compared to the technique of vertebroplasty, kyphoplasty is less riskful but is more time consuming and more expensive. Time will show whether the expected advantage of deformity correction will result in a better outcome for the patient, e. g. in a lower incidence of refractures. (orig.)

    Local neighbourhood environments can influence dietary behavior. There is limited evidence focused on older people who are likely to have greater dependence on local areas and may suffer functional limitations that amplify any neighbourhood impact. Using multi-level ordinal regression analysis we investigated the association between multiple dimensions of neighbourhood food environments (captured by fine-detail, foot-based environmental audits and secondary data) and self-reported frequency of fruit and vegetable intake. The study was a cross-sectional analysis nested within two nationally representative cohorts in the UK: the British Regional Heart Study and the British Women's Heart and Health Study. Main exposures of interest were density of food retail outlets selling fruits and vegetables, the density of fast food outlets and a novel measure of diversity of the food retail environment. A total of 1124 men and 883 women, aged 69 - 92 years, living in 20 British towns were included in the analysis. There was strong evidence of an association between area income deprivation and fruit and vegetable consumption, with study members in the most deprived areas estimated to have 27% (95% CI: 7, 42) lower odds of being in a higher fruit and vegetable consumption category relative to those in the least deprived areas. We found no consistent evidence for an association between fruit and vegetable consumption and a range of other food environment domains, including density of shops selling fruits and vegetables, density of premises selling fast food, the area food retail diversity, area walkability, transport accessibility, or the local food marketing environment. For example, individuals living in areas with greatest fruit and vegetable outlet density had 2% (95% CI: -22, 21) lower odds of being in a higher fruit and vegetable consumption category relative to those in areas with no shops. Although small effect sizes in environment-diet relationships cannot be discounted

    Osteoporosis represents one major health condition for our growing elderly population. It accounts for severe morbidity and increased mortality in postmenopausal women and it is becoming an emerging health concern even in aging men. Screening of the population at risk for bone degeneration and treatment assessment of osteoporotic patients to prevent bone fragility fractures represent useful tools to improve quality of life in the elderly and to lighten the related socio-economic impact. Bone mineral density (BMD) estimate by means of dual-energy X-ray absorptiometry is normally used in clinical practice for osteoporosis diagnosis. Nevertheless, BMD alone does not represent a good predictor of fracture risk. From a clinical point of view, bone microarchitecture seems to be an intriguing aspect to characterize bone alteration patterns in aging and pathology. The widening into clinical practice of medical imaging techniques and the impressive advances in information technologies together with enhanced capacity of power calculation have promoted proliferation of new methods to assess changes of trabecular bone architecture (TBA) during aging and osteoporosis. Magnetic resonance imaging (MRI) has recently arisen as a useful tool to measure bone structure in vivo. In particular, high-resolution MRI techniques have introduced new perspectives for TBA characterization by non-invasive non-ionizing methods. However, texture analysis methods have not found favor with clinicians as they produce quite a few parameters whose interpretation is difficult. The introduction in biomedical field of paradigms, such as theory of complexity, chaos, and fractals, suggests new approaches and provides innovative tools to develop computerized methods that, by producing a limited number of parameters sensitive to pathology onset and progression, would speed up their application into clinical practice. Complexity of living beings and fractality of several physio-anatomic structures suggest

    Background Vertebral fractures are associated with increased morbidity (e.g., pain, reduced quality of life), and mortality. Therapeutic exercise is a non-pharmacologic conservative treatment that is often recommended for patients with vertebral fractures to reduce pain and restore functional movement. Objectives Our objectives were to evaluate the benefits and harms of exercise interventions 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 place boon the incidence of future fractures and adverse events among adults with a history of osteoporotic vertebral fracture(s). We were also examined the effects of exercise on the following secondary outcomes: falls, pain, posture, physical function, balance, mobility, muscle function, quality of life and bone mineral density of the lumbar spine or hip measured using dual-energy X-ray absorptiometry (DXA). We also reported exercise adherence. Search methods We searched the following databases: The Cochrane Library (Issue 11 of 12, November 2011), MEDLINE (2005 to 2011), EMBASE (1988 to November 23, 2011), CINAHL (Cumulative Index to Nursing and Allied Health Literature, 1982 to November 23, 2011), AMED (1985 to November 2011), and PEDro (Physiotherapy Evidence Database, www.pedro.fhs.usyd.edu.au/index.html, 1929 to November 23, 2011. Ongoing and recently completed trials were identified by searching the World Health Organization International Clinical Trials Registry Platform (to December 2009). 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. Selection criteria We considered all randomized controlled trials and quasi-randomized trials comparing exercise or active

PROCEDIMENTOS METODOLÓGICOS: Mediante entrevistas domiciliares face a face, foram estudados 245 homens de 60 a 95 anos, por meio de questionário semiestruturado, anônimo e pré-testado. RESULTADOS: A maior parte dos entrevistados compôs-se de pardos (51,8%, católicos (67,2%, com renda familiar de até dois salários mínimos (71,1% e média de 3,5 anos de estudo. Quase metade classifica sua saúde como regular. Pouco mais de 83% residem com uma companheira e 89,7% destes consideram esse relacionamento como bom ou ótimo. Setenta e três por cento afirmam permanecer sexualmente ativos, sendo os que possuem até 70 anos e que coabitam com uma companheira os de maior frequência sexual. Foi observada associação estatisticamente significativa entre a satisfação sexual atual e a idade, a saúde autopercebida, a satisfação sexual antes dos 60 anos e a frequência sexual. CONCLUSÃO: A sexualidade continua presente na vida dos homens maiores de 60 anos. Não se pode minimizar o papel da cultura na qual estão imersos os entrevistados sobre as questões da masculinidade, da velhice e da sexualidade. A vivência da sexualidade e a interpretação dessas experiências por esses homens têm um caráter plural e assim devem ser encaradas pela sociedade e pelas equipes de saúde da família.OBJECTIVE: Investigate the sexual satisfaction among older men assisted by the Brazilian family health care strategy in city of Recife. METHODOLOGICAL PROCEDURES: A sample of 245 men between 60 and 95 years, assisted by the family health care providers, was face-to-face interviewed, with semi-structured, anonymous, standardized questionnaires. RESULTS: The most were non-white (78%, catholic (67,2%, with median of 3,5 years of study and low economic status. Almost a half perceives their health as regular. 83,3% have a spouse and the most (89

    Full Text Available Background Several studies have examined the association between warfarin sodium use and risk of osteoporotic fractures with conflicting results. Our study addresses this question, for the first time regarding patients attending emergency department (ED. Aims The aim of this study was to retrospectively detect whether there is higher rate of usage of warfarin sodium in patients with osteoporotic fractures attending an ED. Methods This is a retrospective study from patients' computerized charts. All individuals >65 years old who had an osteoporotic fracture and attended an ED in a tertiary hospital were compared with a similar group of elderly individuals >65 years old without an osteoporotic fracture who attended the ED for a cause other than an osteoporotic fracture. Results This study included 328 patients who were evaluated in the years 2005–2016. Overall, 164 individuals with a typical osteoporotic fracture (hip -66 patients (40 per cent, spine- 92 patients (56 per cent, humerus -4 patients (2 per cent, radius -13 patients (8 per cent were identified and compared with a matched group of elderly individuals who were evaluated in the ED for other complaints. Warfarin sodium was used in 61 individuals (19 per cent in the entire cohort, 34 in the fracture group and 27 in the non-fracture group (p=0.324. Conclusion In elderly patients, attending an ED, warfarin sodium use does not seem to be a risk factor for an osteoporotic fracture

    Full Text Available Evolutionary Psychology studies suggest that women prefer slightly older or similarly aged partners, although to date few hypotheses have been put forth to explain this pattern of choice. Several recent studies have shown changes in male reproductive parameters as a result of increased age. In the current review of medical literature, we found evidence that much older men are more likely to be infertile, women with much older partners are more likely to experience problems during pregnancy, and children of much older men are more likely to have genetic abnormalities. Based on these findings, we suggest that reproducing with much older men does not represent the best reproductive option for women, which would explain the female preference for only slightly older or similarly-aged mates.Estudos de Psicologia Evolucionista sugerem que as mulheres preferem parceiros um pouco mais velhos ou de idade semelhante, embora apresentem, até agora, poucas hipóteses para explicar esse padrão de preferência. Recentemente, vários estudos têm demonstrado alterações nos parâmetros reprodutivos masculinos como resultado do aumento da idade. Em revisão da literatura médica atual, encontramos evidências de que homens muito mais velhos são mais susceptíveis de serem inférteis, mulheres com parceiros muito mais velhos são mais propensas a sofrer com problemas durante a gravidez e filhos de homens muito mais velhos são mais propensos a ter anomalias genéticas. Com base nestes resultados, sugerimos que reproduzir com homens muito mais velhos não representa a melhor opção reprodutiva para as mulheres, o que explicaria a preferência feminina por parceiros apenas um pouco mais velhos ou de mesma faixa etária.

    muscles. Pain dependent increase of weight bearing. Continue osteoporosis therapy and start specific drug therapy according to the local guidlines if necessary. In all, 44 patients (29 women, 15 men) with a mean age of 73.5 years with a total of 62 painful osteoporotic vertebral fractures were treated with RF kyphoplasty from May 2009 until July 2010, and followed over a period of 12 months. The mean operating time per patient was 36.2 min, the operating time per vertebra was 25.7 min. All the patients studied experienced an early and persistent significant pain relief even 12 months after therapy (8 ± 1.4 vs. 2.7 ± 1.9) according to the visual analogue pain scale. According to the Oswestry Disability Index (ODI) as a disease-specific disability measure all the patients improved significantly (p < 0.001) in the level of disability after operative treatment (56.2 ± 18.8 vs. 34.5 ± 16.6). Cement leakage was detected in 17 out of 62 (27.4 %) augmented vertebrae, whereas all the patients with cement leakage remained asymptomatic. One patient had subsequent vertebral fractures after a period of 6 months.

    Parental hip fracture (HF) is associated with increased risk of offspring major osteoporotic fractures (MOFs; comprising hip, forearm, clinical spine or humerus fracture). Whether other sites of parental fracture should be used for fracture risk assessment is uncertain. The current study tested the association between objectively-verified parental non-hip MOF and offspring incident MOF. Using population-based administrative healthcare data for the province of Manitoba, Canada, we identified 255,512 offspring with linkage to at least one parent (238,054 mothers and 209,423 fathers). Parental non-hip MOF (1984-2014) and offspring MOF (1997-2014) were ascertained with validated case definitions. Time-dependent multivariable Cox proportional hazards regression models were used to estimate adjusted hazard ratios (HRs) and 95% confidence intervals (95% CIs). During a median of 12 years of offspring follow-up, we identified 7045 incident MOF among offspring (3.7% and 2.5% for offspring with and without a parental non-hip MOF, p hip MOF (HR 1.27; 95% CI, 1.19 to 1.35), paternal non-hip MOF (HR 1.33; 95% CI, 1.20 to 1.48), and any parental non-hip MOF (HR 1.28; 95% CI, 1.21 to 1.36) were significantly associated with offspring MOF after adjusting for covariates. The risk of MOF was even greater for offspring with both maternal and paternal non-hip MOF (adjusted HR 1.61; 95% CI, 1.27 to 2.02). All HRs were similar for male and female offspring (all pinteraction >0.1). Risks associated with parental HF only (adjusted HR 1.26; 95% CI, 1.13 to 1.40) and non-hip MOF only (adjusted HR 1.26; 95% CI, 1.18 to 1.34) were the same. The strength of association between any parental non-hip MOF and offspring MOF decreased with older parental age at non-hip MOF (ptrend  = 0.028). In summary, parental non-hip MOF confers an increased risk for offspring MOF, but the strength of the relationship decreases with older parental age at fracture. © 2016 American Society for Bone and

    The majority of patients do not receive anti-osteoporotic treatment following a major osteoporotic fracture, despite the guidelines and the availability of effective anti-osteoporotic treatments. The fight against factors limiting the diagnosis and treatment of osteoporosis should become a priority to improve secondary prevention after an initial osteoporotic fracture. Despite the availability of effective anti-osteoporotic treatments, osteoporosis management is currently insufficient. The main objective of this study was to assess the prevalence of anti-osteoporotic treatments introduced after an initial prior major osteoporotic fracture during hospitalization for recurring fractures. We conducted an observational, cross-sectional, bicentric study that included all patients aged over 50 years who were hospitalized or seen in consultation for major osteoporotic fracture. One hundred twenty-eight out of two hundred four (62.7%) patients had a past history of major osteoporotic fracture and therefore had an indication of treatment based on guidelines. Among these patients, only 43/128 (33.5%) had received anti-osteoporotic treatment as secondary prevention after the initial fracture. The main causes of non-prescription identified were the attending physicians' ignorance of the indication of treatment (n = 30; 35.3%), ignorance of the fracture (n = 17; 20%), and comorbidities (n = 12; 14.1%). The failure to introduce treatment was associated with the presence of comorbidities with a Charlson Comorbidity Index ≥6 (OR = 0.34 [0.16-0.73], p < 0.05), dementia (OR = 0.23 [0.08-0.72], p < 0.05), and past history of proximal femur fracture (OR = 0.20 [0.04-0.91], p < 0.05). Two thirds of patients with a past history of major osteoporotic fracture presenting with a new fracture were not treated. The main reason for lack of treatment seems to stem from the incorrect assessment of the patient's fracture risk. Although major osteoporotic fracture leads to an

    Full Text Available Osteoporosis is a condition of generalised skeletal fragility caused by diminishing bone amount and disturbance in bone microarchitecture with implication that the bone's ability to withstand forces is decreased. This condition leads to more bone resorption. Some researchers show that this condition also affects jaw bone. Therefore we must take this condition into consideration during prothodontic treatment. Dental prostheses are made to restore stomatognatic function as well as to preserve what was left including alveolar bone. The ability of dental prostheses to preserve residual alveolar bone differs according to type of prostheses. The case presented here propose the treatment of osteoporotic female in Prosthodontics Clinic FKG UI with removable partial denture. Considerations in selecting the type and design of dental prostheses and attempts to modify factors that might play a role in bone resorption in connection with the patient's physical and psychological status will be discussed. Thorough examination, careful planning and good communication with the patient can provide optimum results.

    Full Text Available Several epidemiologic studies suggested that osteoporosis and osteoporotic fractures are not uncommon in South Korea. However, these previous cohort studies had limitations that may have influenced their results and the generalizability of the study conclusions, including small sample sizes, inclusion of only women, enrollment of participants from specific areas, and nonrandom selection of participants. Recently, epidemiologic studies using a nationwide claim register have been performed to overcome these limitations through collaboration between the Korean Society of Bone and Mineral Research and Health Insurance Review Assessments. Our review of the Korean Nationwide-database Osteoporosis Study could be helpful to obtain accurate incidence and prevalence estimations of osteoporosis and osteoporosis-related fractures in Korea.

    This clinical practice guideline is based on a series of systematic reviews of published studies on the treatment of symptomatic osteoporotic spinal compression fractures. Of 11 recommendations, one is strong; one, moderate; three, weak; and six, inconclusive. The strong recommendation is against the use of vertebroplasty to treat the fractures; the moderate recommendation is for the use of calcitonin for 4 weeks following the onset of fracture. The weak recommendations address the use of ibandronate and strontium ranelate to prevent additional symptomatic fractures, the use of L2 nerve root blocks to treat the pain associated with L3 or L4 fractures, and the use of kyphoplasty to treat symptomatic fractures in patients who are neurologically intact.

    This study investigated whether women with cardiovascular disease (CVD) would have an increased risk of fractures as osteoporosis and CVD share many common risk factors. From February 2006 to January 2007, 17,033 women aged ≥50 years (mean 71.8, range 50-106) were recruited by 1,248 primary care practitioners and interviewed by trained nurses. For each woman, 10-year probability of a future major osteoporotic fracture was estimated using the World Health Organization Fracture Risk Assessment Tool (FRAX). The study showed that the 10-year probability of a major osteoporotic fracture was higher for 6,219 CVD women compared to 10,814 non-CVD women after adjustment for age, BMI, current smoking, and alcohol use (adjusted geometric means 14.3 and 13.8%, respectively; P < 0.001). With regard to high risk of fracture (i.e., 10-year probability ≥ 20%), the adjusted odds ratio for CVD was 1.23 (95% CI 1.13-1.35, P < 0.001). However, compared to non-CVD women, CVD women were more likely to report a previous fracture, to have a secondary osteoporosis, and to use glucocorticoids. Among the 4,678 women who were classified as having a high fracture risk, current use rate of bone-related medications (i.e., any one of bisphosphonates, raloxifene, PTH, vitamin D, calcium, or hormone therapy) was 50.2% in the CVD group and 56.9% in the non-CVD group. Women with CVD were at increased risk of fracture partly due to bone-specific risk factors such as history of previous fracture, use of glucocorticoids, and secondary osteoporosis. This risk is not being treated appropriately by primary health physicians.

    Full Text Available Objective: Osteoporotic hip fractures decrease the life expectancy for 20% about 20-50% of the patients become permanently dependent in terms of walking for the rest of their life. Life expectancy is increasing in Turkey in the last 20 years. We investigated the impact of osteoporotic hip fractures which increase the morbidity and mortality on the national economy. Materials and Methods: A total of 81 patients admitted to our emergency department with the diagnosis of femur intertrochanteric fracture and femoral neck fracture between 2008 and 2012 were included in this study. We retrospectively evaluated the medical records and the medical costs of these patients from hospital information management system. Results: Of the 81 patients 32 (39.6% males and 49 (60.4% females meeting the inclusion criteria were included in this study. The mean age was 80.1 years (range, 61-103. Twenty-three (27.5% patients had femoral neck fracture and 58 (72.5% patients had intertrochanteric femur fracture. The mean length of hospital stay was 13.4 days in intertrochanteric femur fracture and 15.5 days in femoral neck fracture; average of the total days of hospitalization of all patients was 13.9 days. The average treatment cost per patient was 5,912.36 TL for intertrochanteric fractures, 5,753.00 TL for neck fractures, and 5,863.09 TL for the whole patient population. Conclusion: Hip fracture is a substantial cause of morbidity and mortality in elderly. Taking preventive measures before the fracture occurs may help to prevent this problem which has a high cost treatment and which is a substantial burden for the national economy.

    Importance Little contemporary information is available about comparative performance between Veterans Affairs (VA) and non-VA hospitals, particularly related to mortality and readmission rates, 2 important outcomes of care. Objective To assess and compare mortality and readmission rates among men in VA and non-VA hospitals. To avoid confounding geographic effects with health care system effects, we studied VA and non-VA hospitals within the same metropolitan statistical area (MSA). Design Cross-sectional analysis between 2010 and 2013 Setting Medicare Standard Analytic Files and Enrollment Database Participants Male Medicare Fee-for-Service beneficiaries aged 65 or older hospitalized between 2010 and 2013 in VA and non-VA acute care hospitals for acute myocardial infarction (AMI), heart failure (HF), or pneumonia. Exposures Hospitalization in a VA or non-VA hospital in urban MSAs that contained at least 1 VA and non-VA hospital Main Outcomes and Measures For each condition, 30-day risk-standardized mortality rates and risk-standardized readmission rates for VA and non-VA hospitals. Mean-aggregated within-MSA differences in mortality and readmission rates were also assessed. Results We studied 104 VA and 1,513 non-VA hospitals, with each condition-outcome analysis cohort for VA and non-VA hospitals containing at least 7,900 patients, in 92 MSAs. Mortality rates were lower in VA hospitals than non-VA hospitals for AMI (13.5% vs. 13.7%, p=0.02; −0.2 percentage point difference) and HF (11.4% vs. 11.9%, p=0.008; −0.5 percentage point difference), but higher for pneumonia (12.6% vs. 12.2%, phospitals for all 3 conditions (AMI: 17.8% vs. 17.2%, 0.6 percentage point difference; HF: 24.7% vs. 23.5%, 1.2 percentage point difference; pneumonia: 19.4% vs. 18.7%, 0.7 percentage point difference, all phospitals had lower mortality rates for AMI (percentage point difference: −0.22, 95% CI: −0.40 to −0.04) and HF (−0.63, 95% CI: −0.95 to −0.31), and mortality

    Fractures are one of the most common causes of disability in older women.The quantity and density of bone decrease with age.Most types of fractures increase as bone density declines.But most of the knowledge about causes and prevention of fractures comes from studies performed in Western countries.Asian women appear to have similar or slightly lower bone density that may be a result of their smaller size.The appear to have a lower risk of hip fracture than Whites.which may be a result of their shorter hip axis.The risks of other types of fractures in Chinese women is less well defined and reasons for differences in the rates of osteoporotic fractures between China and Western countries remain to be expolored.A study is underway in Beijing to describe the risks and potential causes of fractures among older women in urban China.Randomized trials in Western countries have demonstrated that calcium and vitamin D,estrogen,calcitonin,or bisphosphonates can reduce the rate of fractures.Increased intake of calcium and vitamin D may be the most effective approach to preventing fractures in China,but this should be tested be tested in a randomized trial.

    Full Text Available Background. Vertebral fractures are one of the severe complications of systemic osteoporosis, which lead to the low-back pain, decrease or loss of efficiency and increase of mortality in older people. FRAX and dual-energy X-ray absorptiometry (DXA are important methods in determining major osteoporotic fractures risk, including vertebral fractures. Materials and methods. We studied the parameters of Ukrainian model of FRAX in women depending on the presence of vertebral fractures. 652 patients aged 40–89 years examined at the Ukrainian Scientific Medical Center of Osteoporosis were divided into two groups: the first one — 523 women without any previous fractures, the second one — 129 patients with previous vertebral fractures. The assessment of bone mineral density (BMD was performed using DXA (Prodigy, General Electric. The 10-year probability of major osteoporotic fractures (FRAX-MOF and hip fractures (FRAX-HF has been determined using Ukrainian model of FRAX according to two methods — with body mass index (FRAXBMI and BMD. Results. According the distribution of FRAXBMI-MOF parameters in women depending on the presence of vertebral fractures, it was found that index of FRAXBMI-MOF was less than 20 % (the limit indicated as the criterion for treatment initiation in US guidelines in 100 and 100 % of subjects, respectively. The indices of FRAX BMD-HF were less than 3 % (the limit for starting treatment in US guidelines in 95 and 55 % of women, respectively. It was shown the significant moderate correlation between the indices of two methods in all groups for both parameters of the algorithm — FRAX-MOF and FRAX-HF. Conclusions. The study of the age-specific features of FRAX in women depending on the presence of vertebral fractures showed a significant increase in the risks for both major osteoporotic and hip fractures, regardless of the used technique (with BMI or BMD in women with vertebral fractures or without any fractures.

    AJ Wirth

    2010-07-01

    Full Text Available For many years orthopedic implants were developed for patients with good bone stock. Recently it has become clear that these implants have a decreased performance when implanted in bone with low density, such as in osteoporosis. Reduced performance in osteoporotic bone is not unexpected because of the reduced quality of the peri-implant bone and the reduced bone-implant contact area. Nevertheless, the precise failure mechanisms are not well understood. Although experimental testing is considered the gold standard to determine implant fixation, it is hampered by many limitations. Computational models could potentially aid in obtaining a better understanding of implant fixation as they allow analyzing the mechanical interaction between implants and peri-implant tissues. This article provides a review of the existing finite element models of small endosseous implants in bone. The aim is to analyze the potential of such models to aid the understanding of implant failure mechanisms with the goal of improving implant performance in low quality bone.

    2014-01-01

    Full Text Available Kyphoplasty (KP and vertebroplasty (VP have been successfully employed for many years for the treatment of osteoporotic vertebral fractures. The purpose of this review is to resolve the controversial issues raised by the two randomized trials that claimed no difference between VP and SHAM procedure. In particular we compare nonsurgical management (NSM and KP and VP, in terms of clinical parameters (pain, disability, quality of life, and new fractures, cost-effectiveness, radiological variables (kyphosis correction and vertebral height restoration, and VP versus KP for cement extravasation and complications profile. Cement types and optimal filling are analyzed and technological innovations are presented. Finally unipedicular/bipedicular techniques are compared. Conclusion. VP and KP are superior to NSM in clinical and radiological parameters and probably more cost-effective. KP is superior to VP in sagittal balance improvement and cement leaking. Complications are rare but serious adverse events have been described, so caution should be exerted. Unilateral procedures should be pursued whenever feasible. Upcoming randomized trials (CEEP, OSTEO-6, STIC-2, and VERTOS IV will provide the missing link.

  10. Kyphoplasty in osteoporotic vertebral compression fractures - Guidelines and technical considerations

    2011-08-01

    Full Text Available Abstract Osteoporotic vertebral compression fractures are a menace to the elderly generation causing diminished quality of life due to pain and deformity. At first, conservative treatment still is the method of choice. In case of resulting deformity, sintering and persistent pain vertebral cement augmentation techniques today are widely used. Open correction of resulting deformity by different types of osteotomies addresses sagittal balance, but has comparably high morbidity. Besides conventional vertebral cement augmentation techniques balloon kyphoplasty has become a popular tool to address painful thoracic and lumbar compression fractures. It showed improved pain reduction and lower complication rates compared to standard vertebroplasty. Interestingly the results of two placebo-controlled vertebroplasty studies question the value of cement augmentation, if compared to a sham operation. Even though there exists now favourable data for kyphoplasty from one randomised controlled trial, the absence of a sham group leaves the placebo effect unaddressed. Technically kyphoplasty can be performed with a transpedicular or extrapedicular access. Polymethyl methacrylate (PMMA-cement should be favoured, since calcium phosphate cement showed inferior biomechanical properties and less effect on pain reduction especially in less stable burst fractures. Common complications of kyphoplasty are cement leakage and adjacent segment fractures. Rare complications are toxic PMMA-monomer reactions, cement embolisation, and infection.

    Full Text Available Introduction Ochronosis is a rare autosomal recessive disorder of tyrosine metabolism, leading to deposition of elevated levels of homogentisic acid in different parts of the body, especially in fibrous and cartilaginous tissues. The current study presents a case with delayed diagnosis and osteoporotic fracture in addition to severe osteoarthritis and calcification. Case Presentation A 56-year-old female with low back pain and painful knees and hips referred to the center. Right hip arthroplasty was performed to manage her severe osteoarthritis. Although characteristic features of ochronosis such as urine darkening, subcutaneous pigmentation and degenerative ochronotic arthropathy resembling osteoarthritis were observed in this patient, surprisingly it remained unrecognized until the 5th decade. Bone mineral density showed that osteoporosis and zoledronic acid had started. Conclusions Usually, osteoarthritis is inversely correlated with the osteoporosis. Considering ochronosis as an osteoarthritis predisposing factor, the osteoporosis manifestation is not expected in such patients. However, in the current case, simultaneous osteoarthritis and osteoporosis fracture was observed, indicating unreliability of bone mineral density (BMD in such patients. Authors believe that ochronosis could reduce bone quality, while its quantity might increase.

    Full Text Available A validated ovine model of osteoporosis achieves severe bone loss in a relatively short period. This study investigated if osteoporotic features persist in this model after cessation of corticosteroid administration. Methods. Osteoporosis was induced in nine ewes by chronic corticosteroid injection, ovariectomy, and low calcium diet. Six ewes were used as controls. Bone mineral density (BMD of the lumbar spine (LS and body weight were assessed at regular intervals. After five months, corticosteroid treatment was withdrawn systematically over one month. Three months later, all animals were euthanised, and the LS was collected for histomorphometric analysis. Results. BMD in the LS of osteoporotic sheep was 25% lower than control sheep. Body weight of osteoporotic sheep was reduced in the first month of the corticosteroid withdrawal period but returned to baseline level thereafter. Trabecular bone volume of LS in osteoporotic sheep was 27% lower than controls and showed a heterogeneous structure. Conclusions. Osteoporotic characteristics remain in the vertebra after ceasing corticosteroid administration providing an opportunity to evaluate potential systemic or local treatments in vivo under realistic physiological conditions. The microstructural arrangement of vertebral trabecular bone in sheep is similar to humans demonstrating further relevance of this model for preclinical investigations.

    Full Text Available Abstract Background Osteoporosis is a metabolic disorder characterized by a reduction in bone mass and deterioration in the microarchitectural structure of the bone, leading to a higher risk for spontaneous and fragility fractures. The main aim was to study the differences between human bone from osteoporotic and osteoarthritic patients about gene expression (osteogenesis and apoptosis, bone mineral density, microstructural and biomechanic parameters. Methods We analyzed data from 12 subjects: 6 with osteoporotic hip fracture (OP and 6 with hip osteoarthritis (OA, as the control group. All subjects underwent medical history, analytical determinations, densitometry, histomorphometric and biochemical study. The expression of 86 genes of osteogenesis and 86 genes of apoptosis was studied in pool of bone samples from patients with OP and OA by PCR array. Results We observed that most of the genes of apoptosis and osteogenesis show a decrease in gene expression in the osteoporotic group in comparison with the osteoarthritic group. The histomorphometric study shows a lower bone quality in the group of patients with hip fractures compared to the osteoarthritic group. Conclusions The bone tissue of osteoporotic fracture patients is more fragile than the bone of OA patients. Our results showed an osteoporotic bone with a lower capacities for differentiation and osteoblastic activity as well as a lower rate of apoptosis than osteoarthritic bone. These results are related with structural and biochemical parameters.

    Osteoporosis is the most common metabolic bone disease; vertebral fractures are the most common osteoporotic fractures. Several radiological scoring methods using different criteria for osteoporotic vertebral fractures exist. Quantitative morphometry (QM) uses ratios derived from direct vertebral body height measurements to define fractures. Semi-quantitative (SQ) visual grading is performed according to height and area reduction. The algorithm-based qualitative (ABQ) method introduced a scheme to systematically rule out non-fracture deformities and diagnoses osteoporotic vertebral fractures based on endplate depression. The concordance across methods is currently a matter of debate. This article reviews the most commonly applied standardised radiographic scoring methods for osteoporotic vertebral fractures, attaining an impartial perspective of benefits and limitations. It provides image examples and discusses aspects that facilitate large-scale application, such as automated image analysis software and different imaging investigations. It also reviews the implications of different fracture definitions for scientific research and clinical practice. Accurate standardised scoring methods for assessing osteoporotic vertebral fractures are crucial, considering that differences in definition will have implications for patient care and scientific research. Evaluation of the feasibility and concordance among methods will allow establishing their benefits and limitations, and most importantly, optimise their effectiveness for widespread application.

    More than 90% of hip fractures in older Americans result from a fall. Inadequate intake of dietary protein and vitamin D are common in older adults, and diets in low these could contribute to loss of muscle mass and strength or coordination, in turn increasing the risk of falling. The objective of the study was to evaluate the relationship between protein and vitamin D intake with the occurrence of falls in older women in the Study of Osteoporotic Fracture, a prospective cohort of more than 4000 postmenopausal women participating from January 1997 to September 1998. Incident falls were ascertained for one year. Protein and vitamin D intake was assessed by a food frequency questionnaire; associations with a reported fall were estimated with logistic regression, adjusted for fall-related covariates and energy. Protein and vitamin D were modeled separately because of high correlation (rho = 0.55, P protein (per 1 g/kg increase) and vitamin D (per 100 International Unit (IU) increase) significantly increased the odds ratio (OR) of falling (OR 1.35 95% CI 1.15-1.59, OR 1.11 95% CI 1.03-1.19, respectively). Once fall-related covariates were added to each model, dietary protein and vitamin D were noncontributory to falls. While we could find no direct association between vitamin D and protein intake and fall prevention, adequate intake of these two nutrients are critical for musculoskeletal health in older adults.

    Screening in a standardized manner for osteoporosis in non-vertebral fracture patients aged 50 and older independently of both gender and level of trauma energy yielded the indication for osteoporotic therapy for every fourth male high-energy fracture patient. This study aimed to identify the rate of osteoporosis in patients of both genders after fracture independently of the underlying level of trauma energy. A random cohort of patients aged 50 or older with non-vertebral fractures participated in a standardized diagnostic protocol to evaluate the indication for treatment of osteoporosis (number needed to screen (NNS)). Univariate and multivariate analysis as well as correlation testing were performed to determine statistical relationships. Significance was set at p < 0.05. Of 478 fracture patients with a mean age of 69.3 ± 11.8 years, 317 (66.3%) were female and 161 (33.7%) male. One hundred nineteen patients (24.9%) sustained high-energy fractures (HEFs) and 359 (75.1%) low-energy fractures (LEFs). Twenty-eight percent of males and 47% of females qualified as osteoporotic in densitometry (dual-energy X-ray absorptiometry (DXA)), resulting in a NNS of 2.1 for women and 3.6 for men. The indication for treatment of osteoporosis increased to an NNS of 1.5 for females and 2.4 for males if the fracture risk assessment tool (FRAX) was included in the diagnostics (DXA and FRAX). With regard to the energy of trauma, the NNS for treatment following DXA and FRAX was 1.5 for LEF and 2.9 for HEF. Subgroup analysis revealed that HEF males within the decennia 50+ and 80+ had an NNS of around 3, i.e., comparable to females and about twice as high as LEF patients. These preliminary findings appear to confirm the pragmatic approach to screening in a standardized manner for osteoporosis in all non-vertebral fracture patients aged 50 and older-independently of both gender and level of trauma energy.

    Full Text Available Osteoporosis and its associated fracture risk has become one of the major health burdens in our aging population. Currently, bisphosphonate, one of the most popular antiresorptive drugs, is used widely to treat osteoporosis but so far still no consensus has been reached for its application in treatment of osteoporotic fractures. However, in old patients, boosting new bone formation and its remodelling is essential for bone healing in age-related osteoporosis and osteoporotic fractures. Sclerostin, an inhibitor of the Wnt/β-catenin signalling pathway that regulates bone growth, has become an attractive therapeutic target for treating osteoporosis. In this review, we summarize the recent findings of sclerostin and its potential as an effective drug target for treating both osteoporosis and osteoporotic fractures.

    In reconstruction of the osteoporotic spine, patients often show poor outcome because of pedicle screw failure. This study used osteoporotic and nonosteoporotic vertebrae to determine the difference in fixation strength between pedicle screws inserted straight forward and pedicle screws inserted in an upward trajectory toward the superior end plate (i.e., end-plate screws). There is some evidence to suggest that end-plate screws have a strength advantage. The particular focus was on osteoporotic vertebrae. Thirty-three vertebrae (T10-L2) were harvested. The bone mineral density (BMD) was measured: 15 vertebrae were greater than 0.8 g/cm(2) and designated as nonosteoporotic (average BMD 1.146 ± 0.186 g/cm(2)) and 18 vertebrae were designated as osteoporotic (average BMD 0.643 ± 0.088 g/cm(2)). On one pedicle the screw was inserted straight forward and on the other pedicle the screw was inserted as an end-plate screw. The torque of insertion was measured (Proto 6106 torque screwdriver). Using an MTS Mini Bionix, two types of mechanical testing were carried out on each pedicle: (a) cephalocaudad toggling was first carried out to simulate some physiological type loading: 500 cycles at 0.3 Hz, at ±50 N; and (b) then each pedicle screw was pulled out at a displacement rate of 12.5 cm/min.There was no difference in pullout force between the pedicle screws inserted straight forward and the pedicle screws inserted as end-plate screws. This result applies whether the vertebrae were osteoporotic or nonosteoporotic. For both the straight-forward screws and the end-plate screws, a statistically significant correlation was observed between torque of insertion and pullout force. The results of this experiment indicate that pedicle screws inserted as end-plate screws do not provide a strength advantage over pedicle screws inserted straight forward, whether the vertebrae are osteoporotic or not.

    Alendronate and raloxifene, a bisphosphonate and a selective estrogen modulator, respectively, are established osteoporosis therapies. Current evidence suggests that simultaneous application of osteoporosis therapies modulates osseointegration. However, alendronate shows inconsistent findings and raloxifene has not been studied comprehensively. This study aimed to evaluate the bone dynamics and molecular and microstructural features at the peri-implant bone interface in osteoporotic rats. Thirty female rats underwent ovariectomy and were fed a diet low in calcium and phosphate and treated with alendronate or raloxifene for 30 days or underwent fictional ovariectomy surgery (SHAM) prior to implant insertion in the tibia; osteoporosis therapies continued thereafter. After 42 days, peri-implant bone was evaluated by histometric and micro-CT analysis. Fluorochrome incorporation and gene expression was determined to evaluate bone turnover. We report here that alendronate had no impact on bone-to-implant contacts and the mineral apposition rate. The RANKL/OPG ratio and local bone volume, however, were increased compared to the untreated osteoporotic rats. Even though signaling to bone resorption activity through RANKL production was observed in the alendronate group, the blockade of bone resorption activity that occurs in decorrence to alendronate activity took place and resulted in an increase in bone volume. Raloxifene significantly increased osseointegration in osteoporotic rats, as indicated by bone-to-implant contacts, mineral apposition, and local bone volume. Raloxifene, however, had no considerable impact on the RANKL/OPG ratio compared to untreated osteoporotic rats. As expected, the SH group showed higher bone-to-implant contacts and mineral apposition rates than the untreated osteoporotic rats. These findings suggest that raloxifene but not alendronate can compensate for the impaired osseointegration in osteoporotic rats. Regarding the superiority of

  3. Trunk muscle activity is modified in osteoporotic vertebral fracture and thoracic kyphosis with potential consequences for vertebral health.

    Full Text Available This study explored inter-relationships between vertebral fracture, thoracic kyphosis and trunk muscle control in elderly people with osteoporosis. Osteoporotic vertebral fractures are associated with increased risk of further vertebral fractures; but underlying mechanisms remain unclear. Several factors may explain this association, including changes in postural alignment (thoracic kyphosis and altered trunk muscle contraction patterns. Both factors may increase risk of further fracture because of increased vertebral loading and impaired balance, which may increase falls risk. This study compared postural adjustments in 24 individuals with osteoporosis with and without vertebral fracture and with varying degrees of thoracic kyphosis. Trunk muscle electromyographic activity (EMG associated with voluntary arm movements was recorded and compared between individuals with and without vertebral fracture, and between those with low and high thoracic kyphosis. Overall, elderly participants in the study demonstrated co-contraction of the trunk flexor and extensor muscles during forwards arm movements, but those with vertebral fractures demonstrated a more pronounced co-contraction than those without fracture. Individuals with high thoracic kyphosis demonstrated more pronounced alternating flexor and extensor EMG bursts than those with less kyphosis. Co-contraction of trunk flexor and extensor muscles in older individuals contrasts the alternating bursts of antagonist muscle activity in previous studies of young individuals. This may have several consequences, including altered balance efficacy and the potential for increased compressive loads through the spine. Both of these outcomes may have consequences in a population with fragile vertebrae who are susceptible to fracture.

Therefore, our proposal was to investigate whether ­adding 210 g of ricotta cheese daily would improve skeletal muscle mass, handgrip strength, and ­physical performance in non-sarcopenic older subjects.Subjects and methods: This was a single-blind randomized clinical trial that included two homogeneous, randomized groups of men and women over 60 years of age. Participants in the intervention group were asked to consume their habitual diet but add 210 g of ricotta cheese (IG/HD + RCH, while the control group was instructed to consume only their habitual diet (CG/HD. Basal and 12-week follow-up measurements included appendicular skeletal muscle mass (ASMM by dual-energy X-ray absorptiometry, handgrip strength by a handheld dynamometer, and physical performance using the short physical performance battery (SPPB and the stair-climb power test (SCPT. The main outcomes were relative changes in ASMM, strength, SPPB, and SCPT.Results: ASMM increased in the IG/HD + RCH (0.6±3.5 kg, but decreased in the CG/HD (–1.0±2.6. The relative change between groups was statistically significant (P=0.009. The relative change in strength in both groups was negative, but the loss of muscle strength was more pronounced in CG/HD, though in this regard statistical analysis found only a tendency (P=0.07. The relative change in the balance-test scores was positive for the IG/HD + RCH, while in the CG/HD it was negative, as those individuals had

    Low lumbar osteoporotic vertebral collapse (OVC) has not been well documented compared with OVC of the thoracolumbar spine. The differences between low lumbar and thoracolumbar lesions should be studied to provide better treatment. The aim of this study was to clarify the clinical and imaging features as well as outcomes of low lumbar OVC and to discuss the appropriate surgical treatment. Thirty patients (10 men; 20 women; mean age 79.3 ± 4.7 years [range 70-88 years]) with low lumbar OVC affecting levels below L-3 underwent surgical treatment. The clinical symptoms, morphological features of affected vertebra, sagittal spinopelvic alignment, neurological status before and after surgery, and surgical procedures were reviewed at a mean follow-up period of 2.4 years. The main clinical symptom was radicular leg pain. Most patients had old compression fractures at the thoracolumbar level. The affected vertebra was flat-type and concave or H-shaped type, not wedge type as often found in thoracolumbar OVC. There were mismatches between pelvic incidence and lumbar lordosis on plain radiographs. On CT and MR images, foraminal stenosis was seen in 18 patients (60%) and canal stenosis in 24 patients (80%). Decompression with short fusion using a posterior approach was performed. Augmentations of vertebroplasty, posterolateral fusion, and posterior lumbar interbody fusion were performed based on the presence/absence of local kyphosis of lumbar spine, cleft formation, and/or intervertebral instability. Although the neurological and visual analog scale scores improved postoperatively, 8 patients (26.7%) developed postoperative complications mainly related to instrumentation failure. In patients with postoperative complications, lumbar spine bone mineral density was significantly low, but the spinopelvic alignment showed no correlation when compared with those without complications. The main types of low lumbar OVC were flat-type and concave type, which resulted in neurological

    Full Text Available Abstract Background Inadequate serum vitamin D [25(OHD] concentrations are associated with secondary hyperparathyroidism, increased bone turnover and bone loss, which increase fracture risk. The objective of this study is to assess the prevalence of inadequate serum 25(OHD concentrations in postmenopausal Belgian women. Opinions with regard to the definition of vitamin D deficiency and adequate vitamin D status vary widely and there are no clear international agreements on what constitute adequate concentrations of vitamin D. Methods Assessment of 25-hydroxyvitamin D [25(OHD] and parathyroid hormone was performed in 1195 Belgian postmenopausal women aged over 50 years. Main analysis has been performed in the whole study population and according to the previous use of vitamin D and calcium supplements. Four cut-offs of 25(OHD inadequacy were fixed : Results Mean (SD age of the patients was 76.9 (7.5 years, body mass index was 25.7 (4.5 kg/m2. Concentrations of 25(OHD were 52.5 (21.4 nmol/L. In the whole study population, the prevalence of 25(OHD inadequacy was 91.3 %, 87.5 %, 43.1 % and 15.9% when considering cut-offs of 80, 75, 50 and 30 nmol/L, respectively. Women who used vitamin D supplements, alone or combined with calcium supplements, had higher concentrations of 25(OHD than non-users. Significant inverse correlations were found between age/serum PTH and serum 25(OHD (r = -0.23/r = -0.31 and also between age/serum PTH and femoral neck BMD (r = -0.29/r = -0.15. There is a significant positive relation between age and PTH (r = 0.16, serum 25(OHD and femoral neck BMD (r = 0.07. (P Vitamin D concentrations varied with the season of sampling but did not reach statistical significance (P = 0.09. Conclusion This study points out a high prevalence of vitamin D inadequacy in Belgian postmenopausal osteoporotic women, even among subjects receiving vitamin D supplements.

Fourteen patients (5 males, 9 females) who were admitted with proximal femoral fracture following low energy trauma (patients who participated in the light microscopy study) were included. The patients were divided into two groups based on the bone mineral density (BMD) measurement, including osteopenic group (n=7, mean age 69 years; range 63 to 74 years) and osteoporotic group (n=7, mean age 74.1 years; range 67 to 78 years). Cortical and trabecular bone samples were taken from the patients who underwent endoprosthesis during partial hip arthroplasty and these samples were analyzed using transmission electron microscopy and scanning electron microscopy evaluations which are more sophisticated higher resolution techniques. The mean cortical bone thickness was 3622.14 mm in osteopenic group and 2323.14 mm in osteoporotic group (pelectron microscopy and scanning electron microscopy evaluations revealed similar findings for both groups. Although a significant difference in cortical thickness was found between the groups, transmission and scanning electron microscopy confirmed that bone microstructure shared similar characteristics in osteopenic and osteoporotic patients with low-energy femoral neck fracture, as it was in previous light microscopy study.

    Full Text Available Male osteoporosis is a health problem which deserves more attention as nearly 30% of osteoporotic fractures happen in men aged 50 years and above. Although men do not experience an accelerated bone loss phase and testosterone deficiency is not a universal characteristic for aged men, osteoporosis due to age-related testosterone deficiency does have a negative impact on bone health status of men. Observations from epidemiological studies indicate that elderly men with higher testosterone can preserve their BMD better and thus are less prone to fracture. Observations on men with estrogen resistance or aromatase deficiency indicate that estrogen is equally important in the maintenance of bone health status. This had been validated in several epidemiological studies which found that the relationships between estrogen and bone health indices are significant and sometimes stronger than testosterone. Studies on the relationship between quantitative ultrasound and bone remodeling markers suggest that testosterone and estrogen may have differential effects on bone, but further evidence was needed. In conclusion, both testosterone and estrogen are important in the maintenance of bone health in men.

    Masculinity is a social construction that defines itself according to context. Older men constitute an unseen minority when it comes to their health, and thus the study of masculinity as it relates to health in older men requires deeper understanding. This article offers insights into how gender, health, and ageing interact for older men and explores how men negotiate the concept of masculinity in later life. The findings from two complementary studies are presented and discussed. The first study, a qualitative analysis of focus group discussions held with 48 community-dwelling older men, indicates that the desire to uphold hegemonic ideals of independence, self-reliance, and imperviousness to pain and illness are embedded in older men's health-related beliefs and behaviors. Ill health and help seeking are often perceived as a threat to the masculine identity, and taking action for health is considered only when health status jeopardizes independence. In the second study, more than 2,000 men aged 55 to 97 years responded to a postal survey on health behaviors and masculinity. Results of the survey indicated that age predicts health behaviors and health care seeking better than scores on a masculinity index, which tended to remain stable regardless of age. Both the qualitative and quantitative findings support the hypothesis that with age men will succeed in incorporating actions into their daily lives in a way that does not conflict with their perceived resilience to frailty and weakness, even if such actions involve seeking help for illness or adopting healthier lifestyle behaviors.

    Osteoporosis has been described as a progressive skeletal disorder until a patient experiences a fragility fracture. The number of patients with osteoporotic fractures is increasing at an exponential rate. Orthopaedic surgeons, most of the time, first clinicians seen by patients at the time of fracture, do not routinely consider osteoporosis management. Therefore, we compared the knowledge of orthopaedic surgeons and internists regarding medical treatment required: which group would have more abilities to keep patients with osteoporotic fractures under management? We hypothesize that internists may have more abilities to assess and treat osteoporosis for patients with osteoporotic fractures; therefore, referring these patients to this specialized team for post-fracture medical consultation is required. A questionnaire composed of seven closed questions was administered to 4700 orthopaedic surgeons and internists. This question list addressed the orthopaedic surgeons' and internists' knowledge in managing patients with osteoporotic fractures. The questions were designed in a way to cover the topics of diagnosis, treatment, and approach to an osteoporotic patient with osteoporotic fractures. In this survey, 3431 respondents were included. Only 118 (fewer than 10%) orthopaedic surgeons would order bone mineral densitometry (BMD) in osteoporotic fractures in contrast to 1544 (79%) internists. Approximately 1485 (76%) internists against 487 (33%) orthopaedic surgeons prescribe proper dosage of calcium and vitamin D. Typical orthopaedic surgeon is not naturally inclined to manage patients with osteoporotic fractures. The existing management gap between the occurrence of an osteoporotic fracture and the identification and treatment of osteoporosis requires multifaceted intervention. Improved communication between orthopaedic surgeons and internists may reduce this gap between fracture occurrence and osteoporosis management. Level III prospective diagnostic study

    Full Text Available The aims of this study were to investigate the frequency of depression in osteoporotic and osteopenic women and to determine the relationship between depression and lifestyle, level of education and some risk factors of osteoporosis. Sixty-one osteopenic or osteoporotic postmenopausal women were included in this retrospective study. Patients’ lifestyle, risk factors, pain and depression levels were evaluated by means of lifestyle questionnaire, Visual Analog Scale (VAS and Beck Depression Inventory (BDI, respectively. The women were divided into two groups as osteopenic and osteoporotic according to WHO criteria. The mean age and menopause duration of the subjects were 61.7±5.2 and 18.9±9.7 years, respectively. Fourty-six percent of women were found to be osteoporotic and the remainig were osteopenic according to the bone density measurement. As the results of lifestyle questionnaire, 73.8% of the patients were housewife, 45.9% graduated from primary school, and 14.8% were exercising regularly. The mean VAS and BDI scores were 5.4±2.01 cm and 17.2±9.8, respectively. According to BDI scores, 30.8% of women had moderate, and 7.7% had severe depression. There were negative correlations between BDI score and education level (r= -0.300, p= 0.031, as well as BDI and history of exercise (r=-0.285, p=0.041. However, positive correlations were found between exercise and level of education (r=0.340 p=0.007, and Hormone Replacement Therapy (HRT (r=0.430 p=0.001. In conclusion, depression being commonly seen in osteoporotic and osteopenic patients should be taken into account in the treatment and follow-up of patients. In these patients it should be taken into consideration that lifestyle properties like education, dressing, HRT usage, and exercise could have a relation with depression and with each other.

    This study was conducted to test the ability of quantitative ultrasound technique (QUS) at the phalanges to discriminate between uremic and osteoporotic patients. Three groups of subjects (38 dialytic women, 16 osteoporotic women with vertebral fractures, 19 non-dialytic and non-fractured women) were recruited at the Department of Radiology at 'Casa Sollievo della Sofferenza' Hospital, San Giovanni Rotondo, Italy. The groups were matched for age and body mass index (BMI). On all subjects the following measurements were performed: spinal BMD by QCT and by DXA, Femoral BMD by DXA, phalangeal QUS. For QUS measurements, the DBM Sonic (IGEA, Carpi, Italy) was applied to the metaphysis of the proximal phalanges of the last four fingers of the hand. Osteoporotic women with vertebral fractures showed significantly lower values of spinal BMD by QCT and DXA and Ward's Triangle BMD with respect to hemodialytic patients (p < 0.005). All QUS values, except for BTT and SoS, showed lower values in osteoporotic women with respect to hemodialytic patients (p < 0.05). Control group showed higher values of AD-SoS, BTT and SoS than hemodialytic patients (p < 0.005) while the two groups did not differ for BMD values measured with both QCT and DXA. UBPI and FWA data showed a similar behaviour to DXA and QCT results, whereas BTT and SoS showed a completely different behaviour. AD-SoS was the only parameter that could effectively discriminate among the three groups (ANOVA, p < 0.0001). We conclude that phalangeal QUS can discriminate between hemodialysed patients and controls with similar bone mineral density, and can also discriminate between hemodialysed and osteoporotic subjects with vertebral fractures. Different characteristics of ultrasound signal can be ascribed to each bone tissue condition, enabling a clear differentiation of bone tissue changes occurring in menopause, osteoporosis and renal osteodystrophy.

    Older adults (≥60 years) perform worse than young adults (18-30 years) when recognizing facial expressions of emotion. The hypothesized cause of these changes might be declines in neurotransmitters that could affect information processing within the brain. In the present study, we examined the neuropeptide oxytocin that functions to increase neurotransmission. Research suggests that oxytocin benefits the emotion recognition of less socially able individuals. Men tend to have lower levels of oxytocin and older men tend to have worse emotion recognition than older women; therefore, there is reason to think that older men will be particularly likely to benefit from oxytocin. We examined this idea using a double-blind design, testing 68 older and 68 young adults randomly allocated to receive oxytocin nasal spray (20 international units) or placebo. Forty-five minutes afterward they completed an emotion recognition task assessing labeling accuracy for angry, disgusted, fearful, happy, neutral, and sad faces. Older males receiving oxytocin showed improved emotion recognition relative to those taking placebo. No differences were found for older females or young adults. We hypothesize that oxytocin facilitates emotion recognition by improving neurotransmission in the group with the worst emotion recognition.

    2012-01-01

    Osteoporosis is associated with compromised quality of life (QOL), to which pain has the most important contribution. Elcatonin, a derivative of calcitonin, is widely used in the treatment of osteoporosis in two ways. One is as the inhibitor of osteoclastic bone resorption. The other is for osteoporosis-related pain based on the unique analgesic effects of elcatonin. Since pain is subjective in nature, and QOL is the only clinical outcome representing the patients' subjective perception of health status, pain associated with osteoporosis would be best evaluated based on QOL assessment. Evidence based medicine gives the highest remarks to the double-blinded, randomized controlled trial, which, however, cannot be free from methodological problems on some occasions. For example, it is practically impossible to remain blinded in the trial of a potent analgesia, which in turn causes biases. Thus, the significance of taking the patients' preference into account is increasingly acknowledged. In this study, 45 osteoporotic patients were given brochures describing the pros and cons on the three treatment choices; calcium and alfacalcidol, additional use of elcatonin, and additional use of bisphosphonate. Those who favored elcatonin were older, had more vertebral fractures, and lower QOL scores. QOL was evaluated before and three months after the treatment using SF-8; the most widely used generic questionnaire, and RDQ; a lumbago-specific measure. Elcatonin treatment improved physical function, general health, and vitality of SF-8, and RDQ score. Although this is a preliminary study, our results suggest that patients with vertebral fracture(s) have impaired QOL and more likely to favor elcatonin treatment expecting analgesia.

  7. Serum 25-hydroxyvitamin D levels are associated with functional capacity but not with postural balance in osteoporotic postmenopausal women

    Directory of Open Access Journals (Sweden)

    Guilherme Carlos Brech

    Full Text Available OBJECTIVES: In post-menopausal women with osteoporosis, insufficient vitamin D levels decrease calcium fixation in the bones and calcium transport in the sarcoplasmic reticulum, which impairs muscle strength, possibly leading to detrimental consequences for the preservation of functional capacity and postural balance, fall prevention, and fracture risk. The aim of this study was to evaluate the association between vitamin D levels and knee muscle strength, postural balance and functional mobility among postmenopausal women with osteoporosis. METHODS: This cross-sectional study included 63 osteoporotic older women (aged 60.6±3.1 years. The subjects completed the Timed Up and Go Test to measure functional mobility, and postural balance was assessed on the AccuSway Plus portable force platform. Maximal strength was tested using an isokinetic dynamometer for knee flexion and extension. The subjects were assessed as a group and were divided into quartiles according to their vitamin D levels. Clinicaltrials.gov: NCT02771834. RESULTS: Vitamin D status was independently associated with the normalized peak torque of the knee extensors (β=0.59; p=0.04 and Timed Up and Go Test (β=-0.07; p<0.001. No between-group differences were observed in the demographic and clinical variables or postural balance; however, significant differences were observed in the Timed Up and Go Test, and the group with the highest vitamin D levels exhibited better performance than the group with the lowest vitamin D levels (p<0.001. CONCLUSION: The serum vitamin D levels were independently associated with normalized knee extension strength and functional mobility in postmenopausal women with osteoporosis.

    Morquio A syndrome (Mucopolysaccharidosis type IVA) (MPS IVA) is a rare inherited metabolic disorder characterized by the defective degradation of keratan sulfate and chondroitin-6-sulfate. Classically, MPS IVA patients present with severe multisystemic involvement and have a short life expectancy. Attenuated forms with clinical features limited to minor skeletal abnormalities and short stature have also been described, sometimes associated to an early-onset osteoporotic phenotype. No treatment with allogenic bone marrow transplantation or gene therapy is currently available for Morquio A syndrome, and enzyme replacement therapy is under evaluation. We report a case of MPS IVA, who manifested tardily attenuated phenotype and significant bone mass reduction, which was treated with a bisphosphonate (BPN), resulting in an improvement of X-ray skeletal aspects and functional bone performance. We suggest that the use of bisphosphonates may be an interesting supportive therapeutic option for Morquio A patients with osteoporotic phenotype, but further studies involving more patients are necessary to confirm our findings.

  11. Podoplanin immunopositive lymphatic vessels at the implant interface in a rat model of osteoporotic fractures.

    Directory of Open Access Journals (Sweden)

    Katrin Susanne Lips

    Full Text Available Insertion of bone substitution materials accelerates healing of osteoporotic fractures. Biodegradable materials are preferred for application in osteoporotic patients to avoid a second surgery for implant replacement. Degraded implant fragments are often absorbed by macrophages that are removed from the fracture side via passage through veins or lymphatic vessels. We investigated if lymphatic vessels occur in osteoporotic bone defects and whether they are regulated by the use of different materials. To address this issue osteoporosis was induced in rats using the classical method of bilateral ovariectomy and additional calcium and vitamin deficient diet. In addition, wedge-shaped defects of 3, 4, or 5 mm were generated in the distal metaphyseal area of femur via osteotomy. The 4 mm defects were subsequently used for implantation studies where bone substitution materials of calcium phosphate cement, composites of collagen and silica, and iron foams with interconnecting pores were inserted. Different materials were partly additionally functionalized by strontium or bisphosphonate whose positive effects in osteoporosis treatment are well known. The lymphatic vessels were identified by immunohistochemistry using an antibody against podoplanin. Podoplanin immunopositive lymphatic vessels were detected in the granulation tissue filling the fracture gap, surrounding the implant and growing into the iron foam through its interconnected pores. Significant more lymphatic capillaries were counted at the implant interface of composite, strontium and bisphosphonate functionalized iron foam. A significant increase was also observed in the number of lymphatics situated in the pores of strontium coated iron foam. In conclusion, our results indicate the occurrence of lymphatic vessels in osteoporotic bone. Our results show that lymphatic vessels are localized at the implant interface and in the fracture gap where they might be involved in the removal of

    2001-01-01

    Objective: To observe the effect of recombinant human growthhormone (r-hGH) on osteoporotic fracture healing in rats, and to provide an effective therapy for osteoporotic fracture.Methods: Thirty-six female 8-month-old SD rats were randomized into two groups: therapy group and control group. After the experimental model of osteoporotic fracture was established, the therapy group was treated with r-hGH of 2.7 mg/kg body weigh/day (1 mg=3 IU) for 10 days continuously by daily subcutaneous injection; whereas the control group was treated with equivalent saline. Plasma insulin-like growth factor I concentration was detected and bone mineral density (BMD) as well as biomechanical strength of callus were measured at 2, 4, 8 weeks.Results: Plasma insulin-like growth factor I concentration in the therapy group was higher than that in the control group (P<0.005) at 2nd week and began to decline at 4th week. At 8th week, there was no significant difference between the two groups. At 4th week, callus area and BMD in therapy group were higher than those in the control group, but at 8th week, they were lower and BMD had a significant difference between the two groups (P<0.001). Biomechanical testing of callus showed that torsional strength of the therapy group was higher than that of the control group at 4th or 8th week, meanwhile maximum torsional angle had a significant difference between the two groups (P<0.005).Conclusions: The results show that exogenous r-hGH can stimulate osteoporotic fracture healing in rats.

    2008-01-01

    Full Text Available Abstract Background Kyphoplasty represents an established minimal-invasive method for correction and augmentation of osteoporotic vertebral fractures. Reliable data on perioperative and postoperative complications are lacking in the literature. The present study was designed to evaluate the incidence and patterns of perioperative complications in order to determine the safety of this procedure for patients undergoing kyphoplasty. Patients and Methods We prospectively enrolled 102 consecutive patients (82 women and 20 men; mean age 69 with 135 operatively treated fractured vertebrae who underwent a kyphoplasty between January 2004 to June 2006. Clinical and radiological follow-up was performed for up 6 months after surgery. Results Preoperative pain levels, as determined by the visual analogous scale (VAS were 7.5 +/- 1.3. Postoperative pain levels were significantly reduced at day 1 after surgery (VAS 2.3 +/- 2.2 and at 6-month follow-up (VAS 1.4 +/- 0.9. Fresh vertebral fractures at adjacent levels were detected radiographically in 8 patients within 6 months. Two patients had a loss of reduction with subsequent sintering of the operated vertebrae and secondary spinal stenosis. Accidental cement extravasation was detected in 7 patients in the intraoperative radiographs. One patient developed a postoperative infected spondylitis at the operated level, which was treated by anterior corporectomy and 360 degrees fusion. Another patient developed a superficial wound infection which required surgical revision. Postoperative bleeding resulting in a subcutaneous haematoma evacuation was seen in one patient. Conclusion The data from the present study imply that percutaneous kyphoplasty can be associated with severe intra- and postoperative complications. This minimal-invasive surgical procedure should therefore be performed exclusively by spine surgeons who have the capability of managing perioperative complications.

    In this study, the characteristics of the alveolar bone of rats with induced osteoporosis were examined. Thirty-two rats were divided into four groups according to the induction of osteoporosis and drugs administered: OG, osteoporotic rats without treatment (negative control); SG, rats which underwent sham surgery ovariectomy (SHAM); alendronate (AG), osteoporotic rats treated with alendronate; and RG, osteoporotic rats treated with raloxifene (RG). On the 8th day after ovariectomy and SHAM surgeries, drug therapy was started with AG or RG. On the 52nd day, 20 mg/kg calcein was administered to all of the rats, and on the 80th day, 20 mg/kg alizarin red was administered. Euthanasia was performed on the 98th day. The bone area marked by fluorochromes was calculated and data were subjected to two-way ANOVA test and Tukey's post-hoc test (pbone turnover only between RG and SG (p=0.074) and AG and OG (p=0.138). All other comparisons showed significant differences (pbone turnover was observed in RG and SG groups. RG was the medication that improved the dynamics of the alveolar bone of rats with induced osteoporosis, resembling that of healthy rats.

  16. Implants delivering bisphosphonate locally increase periprosthetic bone density in an osteoporotic sheep model. A pilot study

    Full Text Available It is a clinical challenge to obtain a sufficient orthopaedic implant fixation in weak osteoporotic bone. When the primary implant fixation is poor, micromotions occur at the bone-implant interface, activating osteoclasts, which leads to implant loosening. Bisphosphonate can be used to prevent the osteoclastic response, but when administered systemically its bioavailability is low and the time it takes for the drug to reach the periprosthetic bone may be a limiting factor. Recent data has shown that delivering bisphosphonate locally from the implant surface could be an interesting solution. Local bisphosphonate delivery increased periprosthetic bone density, which leads to a stronger implant fixation, as demonstrated in rats by the increased implant pullout force. The aim of the present study was to verify the positive effect on periprosthetic bone remodelling of local bisphosphonate delivery in an osteoporotic sheep model. Four implants coated with zoledronate and two control implants were inserted in the femoral condyle of ovariectomized sheep for 4 weeks. The bone at the implant surface was 50% higher in the zoledronate-group compared to control group. This effect was significant up to a distance of 400µm from the implant surface. The presented results are similar to what was observed in the osteoporotic rat model, which suggest that the concept of releasing zoledronate locally from the implant to increase the implant fixation is not species specific. The results of this trial study support the claim that local zoledronate could increase the fixation of an implant in weak bone.

    In Middle-Eastern countries, more particularly in Lebanon, the incidence of vitamin D deficiency has been found to be surprisingly high in schoolchildren and young individuals. However, the prevalence and risk factors for vitamin D inadequacy amongst Lebanese osteoporotic women seeking medical health care has never been studied. We analysed vitamin D-inadequacy risk factors among the 251 Lebanese postmenopausal osteoporotic women (from both Muslim and Christian communities) who participated in a vitamin D international epidemiological study. Vitamin D inadequacy prevalence (25-hydroxyvitamin D (25(OH)D) , 30 ng/ml) was 84.9%. 25(OH)D was negatively correlated with BMI (r 20.41; Pdress code covering the arms (Pdress code covering the arms are the independent predictors of 25(OH)D inadequacy (P<0.001 for both variables). However, in Christians, the predictors are inadequate vitamin D supplements, high BMI and low educational level (P<0.001; P=002 and P=0.02 respectively). There is an urgent need to increase vitamin D supplement use in Middle-Eastern osteoporotic women, more particularly in those from the Muslim community.

    Background The use of osteoanabolic agents to facilitate fracture healing has been of heightened interest to the field of orthopaedic trauma. This study aimed to evaluate the evidence of teriparatide for fracture healing and functional recovery in osteoporotic patients. Methods We performed a literature search in PubMed, EMBASE, Web of Science, and the Cochrane Library using terms including “Fracture” [tiab] AND “Teriparatide [tiab] OR “PTH” [tiab]. Results This systematic review included 6 randomized clinical trials, 4 well-controlled retrospective studies, and 1 retrospective post hoc subgroup analysis. Fracture location was 2 in pelvis, 3 in proximal femur, 1 in distal femur, 1 in shoulder, 2 in wrist and 2 in spine. The use of teriparatide yielded positive effects on radiographic bone healing in 6 studies, but was not associated with better radiographic outcome in 3. In terms of functional recovery, teriparatide injection was related with decrease in pain or shorter time to mobilization in 6 studies, but not related with pain numerical scale and mobility in 3. Conclusions Our findings suggest that teriparatide provide selective advantages to fracture healing or functional recovery in the management of osteoporotic fractures. A better understanding of the role of teriparatide on osteoporotic fractures requires greater evidences from large volume prospective trials. PMID:28326303

    Several common age-related mechanisms and factors influence muscle and bone, affecting functionality of both tissues. Sarcopenia is closely linked with osteoporosis, and their combined effect may exacerbate negative health outcomes. Fall-related fractures are some of the most serious consequences of these two systemic pathologies, with hip fracture being a major complication affecting osteoporotic and sarcopenic elderly. This work aims to review the literature on the current state of knowledge about the relations between sarcopenia and osteoporosis and to present the association between sarcopenia and osteoporosis and the risk of hip fracture. A literature search was performed in PubMed and Scopus databases for articles with the predefined terms "sarcopenia," "muscular atrophy," "femoral fractures," "hip fractures," "osteoporosis," and "bone density." There is a growing and significant interest being directed to sarcopenia and associated risk for osteoporotic hip fracture, but there still is a notorious heterogeneity in the methodology and cohort size of the available studies. Collectively, most of the studies herein analyzed indicate that sarcopenia could be a predictor of risk for hip fracture. The simultaneous evaluation of sarcopenia and osteoporosis may be of importance in identifying those patients in higher risk of suffering an osteoporotic hip fracture and who could benefit from preventive or therapeutic interventions, or both.

    Full Text Available Aim: The purpose of this multicenter descriptive study is to determine the preferences of physiatrists in our country for anti-osteoporotic drugs in patients with primary and secondary osteoporosis. Materials and Methods: This study was carried out in 10 provinces of Turkey. The diagnosis of osteoporosis was based on World Health Organization criteria using dual-energy x-ray absorptiometry. Patients with a spine and/or hip T-score ≤-2.5 were considered as osteoporotic. 714 patients over 18 years old with primary or secondary osteoporosis were included in the study. In addition to socio-demographic characteristics and chronic use of medications and/or additional systemic diseases that cause secondary osteoporosis were questioned and antiosteoporotic drugs that are recommended by their physicians were recorded.Results: The physicians’ preferred vitamin D and calcium as the prior treatment both in primary and secondary osteoporosis. The most commonly used anti-osteoporotic agent was alendronate from the biphosphonate group. It was followed by ibandronate, risedronate, strontium ranelate, calcitonin, zoledronate, raloxifene, parathyroid hormone (PTH and hormone replacement therapy (HRT in the primary osteoporosis and risedronate, ibandronate, calcitonin, strontium ranelate, zoledronate, PTH, HRT and raloxifene in the secondary osteoporosis, respectively. Conclusion: The physician should choose the most suitable treatment for the patient based on fracture risk, medical history, previous treatments for osteoporosis, concomitant diseases, treatment-induced risks and benefits, and the relation between financial cost and potential benefit.

    The purpose of this study was to evaluate the influences of helium-neon (He-Ne) and infrared (IR) lasers on the viability and proliferation rate of healthy and ovariectomy-induced osteoporotic (OVX) bone marrow mesenchymal stem cells (BMMSCs) in vitro. MSCs harvested from the BM of healthy and OVX rats were culture expanded. He-Ne and IR lasers were applied three times at energy densities of 0.6, 1.2, and 2.4 J/cm2 for BMMSCs. BMMSCs viability and proliferation rate were evaluated by MTT assay on days 2, 4, 6, 14, and 21. The results showed that healthy BMMSCs responded optimally to 0.6 J/cm2 using an IR laser after three times of laser radiation. Moreover, it was found that OVX-BMMSCs responded optimally to 0.6 J/cm2 with He-Ne laser and one-time laser radiation. It is concluded that the low-level laser therapy (LLLT) effect depends on the physiological state of the BMMSCs, type of the laser, wavelength, and number of laser sessions. The biostimulation efficiency of LLLT also depends on the delivered energy density. LLLT can enhance the viability and proliferation rate of healthy and especially osteoporotic autologous BMMSCs, which could be very useful in regenerative medicine.

    Full Text Available Objective. The aim of this study was to evaluate sex specific differences of metabolic and clinical characteristics of treated hyperlipidemic men and women (HL-men and HL-women. Methods. In this study vascular and metabolic characteristics of 35 HL-women and 64 HL-men were assessed. In addition a sex specific analysis of metabolic and nutritional habits of HL-patients with prediabetes (HL-IGR was done. Results. HL-women were older and had favourable concentrations of high density lipoprotein cholesterol (HDL-cholesterol, triglycerides (TG, and triglyceride/HDL-cholesterol ratio (TG/HDL-ratio but were also shown to have higher concentrations of lipoprotein-a compared to HL-men. HL-men were characterized as having higher levels of liver-specific parameters and body weight as well as being more physically active compared to HL-women. Brain natriuretic peptide (pro-BNP was higher in HL-women than HL-men, while no differences in metabolic syndrome and glycemic parameters were shown. HL-IGR-women were also older and still had a better profile of sex specific lipid parameters, as well as a lower body weight compared to HL-IGR-men. No differences were seen in vascular parameters such as the intima media thickness (IMT. Conclusion. HL-women were older and had overall more favourable concentrations of lipid parameters and liver enzymes but did not differ regarding vascular morphology and insulin sensitivity compared to HL-men of comparable body mass index (BMI.

    Introduction Oftentimes the older adults are assumed to be asexual as few studies explore into the sexuality of this age group worldwide and even in Nigeria. It is an important aspect of quality of life which is often neglected by people in this age group, attending physicians and the society as a whole. The study was aimed at determining the perception of older adults about sexuality, identify the factors that could militate against sexuality and fill any void in information in this regard. Methods Descriptive study conducted in one hundred older adults. A semi-structured questionnaire was administered to consenting participants between 1st of September 2013 and 31st of March 2014. Results Mean age of respondents was 66.42± 5.77 years. Seventy-eight percent of the male respondents considered engaging in sexual activity as safe compared to 45.8% of the female respondents. More of the women (33.3%) regarded sexuality in the older adults as a taboo when compared to the men (5.4%). However, the men were more favourably disposed to discussing sexual problems than the women with their spouses (42% vs 20%) and Physicians (23.2% vs 0.0%). Major factors responsible for sexual inactivity were participants’ medical ailments (65%), partners’ failing health (15%) as well as anxiety about sexual performance (25%) in the men and dyspareunia (25%) in women. Conclusion There is an urgent need to correct the misconception about sexuality in this age group especially among the women and for the physicians to explore the sexual history of every patient.

    Full Text Available Abstract Background Knowledge on the epidemiology of non-hip fractures in Spain is limited and somewhat outdated. Using computerized primary care records from the SIDIAP database, we derived age and sex-specific fracture incidence rates for the region of Catalonia during the year 2009. Methods The SIDIAP database contains quality-checked clinical information from computerized medical records of a representative sample of >5,800,000 patients (80% of the population of Catalonia. We conducted a retrospective cohort study including all patients aged ≥50 years, and followed them from January 1 to December 31, 2009. Major osteoporotic fractures registered in SIDIAP were ascertained using ICD-10 codes and validated by comparing data to hospital admission and patient-reported fractures records. Incidence rates and 95% confidence intervals were calculated. Results In total, 2,011,430 subjects were studied (54.6% women. Overall fracture rates were 10.91/1,000 person-years (py [95%CI 10.89–10.92]: 15.18/1,000 py [15.15–15.21] in women and 5.78/1,000 py [5.76–5.79] in men. The most common fracture among women was wrist/forearm (3.86/1,000 py [3.74–3.98], while among men it was clinical spine (1.25/1,000 py [1.18–1.33]. All fracture rates increased with age, but varying patterns were observed: while most of the fractures (hip, proximal humerus, clinical spine and pelvis increased continuously with age, wrist and multiple rib fractures peaked at age 75–80 and then reached a plateau. Conclusions Our study provides local estimates of age, sex and site-specific fracture burden in primary health care, which will be helpful for health-care planning and delivery. A proportion of fractures are not reported in primary care records, leading to underestimation of fracture incidence rates in these data.

    In this study, 432 television advertisements from Hong Kong, Japan, and South Korea were analyzed to determine their representations of older people. Findings demonstrate that in East Asian advertisements, older people are highly underrepresented, appear in major roles, mostly alongside younger people, and older men clearly outnumber older women. The other variables investigated (i.e., setting and product categories) led to no conclusive findings for the three societies. In short, our study, employing ethnolinguistic vitality theory to analyze television advertisements, demonstrates how East Asian societies greatly marginalize older people. Potential effects of such representations are discussed using social cognitive theory and cultivation theory.

  8. The Epidemiology of Hip and Major Osteoporotic Fractures in a Dutch Population of Community-Dwelling Elderly: Implications for the Dutch FRAX® Algorithm.

    Full Text Available Incidence rates of non-hip major osteoporotic fractures (MOF remain poorly characterized in the Netherlands. The Dutch FRAX® algorithm, which predicts 10-year probabilities of hip fracture and MOF (first of hip, humerus, forearm, clinical vertebral, therefore incorporates imputed MOF rates. Swedish incidence rate ratios for hip fracture to MOF (Malmo 1987-1996 were used to perform this imputation. However, equality of these ratios between countries is uncertain and recent evidence is scarce. Aims were to estimate incidence rates of hip fracture and MOF and to compare observed MOF rates to those predicted by the imputation method for the Netherlands.Using hospitalisation and general practitioner records from the Dutch PHARMO Database Network (2002-2011 we calculated age-and-sex-specific and age-standardized incidence rates (IRs of hip and other MOFs (humerus, forearm, clinical vertebral and as used in FRAX®. Observed MOF rates were compared to those predicted among community-dwelling individuals ≥50 years by the standardized incidence ratio (SIR; 95% CI.Age-standardized IRs (per 10,000 person-years of MOF among men and women ≥50 years were 25.9 and 77.0, respectively. These numbers were 9.3 and 24.0 for hip fracture. Among women 55-84 years, observed MOF rates were significantly higher than predicted (SIR ranged between 1.12-1.50, depending on age. In men, the imputation method performed reasonable.Observed MOF incidence was higher than predicted for community-dwelling women over a wide age-range, while it agreed reasonable for men. As miscalibration may influence treatment decisions, there is a need for confirmation of results in another data source. Until then, the Dutch FRAX® output should be interpreted with caution.

    Oettel, Michael

    The review starts off by outlining the history of the discovery of the male sex hormone testosterone and the historical background to the various, often dubious, approaches to the treatment of age-related endocrine disorders in older men. A discussion of congenital androgen deficiency in young men is followed by methods of diagnosing hypogonadism in older men. Among therapeutic options, the alternatives to direct testosterone replacement are discussed, although none of them have proved to be particularly successful in clinical practice. For testosterone replacement itself, various routes of administration and pharmaceutical formulations are now available, facilitating good monitoring and individualized therapy.

    The authors examined hepatitis A virus (HAV) and hepatitis B virus (HBV) vaccination rates, hepatitis infection, and health care access in a gym-attending sample of 311 gay, bisexual, and other men who have sex with men (MSM) in New York City. Overall, 69% reported having been vaccinated for HAV and 70% reported having been vaccinated for HBV. Multivariate models were used to identify predictors of HAV and HBV vaccination, and younger men, HIV-positive men, and men who had access to a doctor or clinic were more likely to be vaccinated than older men, HIV-negative men, and men without access to a doctor or clinic. Men with health insurance coverage were more likely to have received HBV vaccination than men without coverage. Findings indicate that there is still a significant proportion of unvaccinated men in our sample.

    2014-01-01

    From research findings and practice experiences, it is concluded that abuse of older men is especially invisible and underreported, compared to abuse of older women. It is proposed that attention should be directed not to gender, but to those conditions in different countries and cultures leading to abuse of both older men and women, including (but not limited to) economic problems, few alternatives to family care of the elderly, violence, changing characteristics of the family, ageism, and sexism. Advocates for the prevention of elder abuse should work together in combating, reducing, and eliminating the problem of elder abuse of both older men and older women.

    Case report. This study reports if shortening reconstruction procedure through posterior approach only can be used in osteoporotic unstable fracture as well as post-traumatic burst fracture. An 80-year-old female patient with unstable burst osteoporotic fracture of L1 underwent posterior approach corpectomy and shortening reconstruction of the spinal column by non-expandable cages. The surgery was uneventful, with average blood loss. Using of small profile cages has helped us to avoid root injury. Augmentation of the screw with cement and the compressive force applied to the spine column aids in obtaining a rigid construct with good alignment without any neurological complication. Shortening reconstruction procedure through only posterior approach is a viable option in treating unstable osteoporotic fracture as well as post-traumatic fractures. Using non-expandable cage is advocated to avoid cage subsidence.

    Men's Sheds are community-based organisations that typically provide a space for older men to participate in meaningful occupation such as woodwork. Men's Sheds are considered an exemplar for the promotion of men's health and well-being by health and social policy-makers. The objective of this literature review was to determine the state of the science about the potential for Men's Sheds to promote male health and well-being. Between October 2011 and February 2012, we conducted searches of databases, the grey literature and manual searches of websites and reference lists. In total, we found 5 reports and 19 articles about Men's Sheds. The majority of the literature has emanated from Australian academics and is about older men's learning in community contexts. There is a limited body of research literature about Men's Sheds; the literature consists of either descriptive surveys or small qualitative studies. The range of variables that might contribute towards best practice in Men's Sheds has not yet been adequately conceptualised, measured, tested or understood. Future research should be focussed on the health and well-being benefits of Men's Sheds; it needs to incorporate social determinants of health and well-being within the study designs to enable comparison against other health promotion research. Without this research focus, there is a danger that the potential health and well-being benefits of Men's Sheds as supportive and socially inclusive environments for health will not be incorporated into future male health policy and practice.

    Full Text Available Abstract Background Although not as common as in women, osteoporosis remains a significant health care problem in men. Data concerning risk factors of osteoporosis are lacking for the male Moroccan population. The objective of the study was to identify some determinants associated to low bone mineral density in Moroccan men. Methods a sample of 592 healthy men aged 20-79 years was recruited from the area of Rabat, the capital of Morocco. Measurements were taken at the lumbar spine and proximal femurs using DXA (Lunar Prodigy Vision, GE. Biometrical, clinical, and lifestyle determinants were collected. Univariate, multivariate, and logistic regression analyses were performed. Results the mean (SD age of the patients was 49 (17.2 years old. The prevalence of osteoporosis and osteopenia were 8.7% and 52.8%, respectively. Lumbar spine and hip BMD correlated significantly with age, weight and BMI. When comparing the subjects according to the WHO classification, significant differences were revealed between the three groups of subjects for age, weight and BMI, prevalence of low calcium intake and low physical activity. The multiple regression analysis found that only age, BMI, and high coffee consumption were independently associated to the osteoporotic status. Conclusion ageing and low BMI are the main risk factors associated with osteoporosis in Moroccan men.

    To develop a prototype algorithm for automatic spine segmentation in MDCT images and use it to automatically detect osteoporotic vertebral fractures. Cross-sectional routine thoracic and abdominal MDCT images of 71 patients including 8 males and 9 females with 25 osteoporotic vertebral fractures and longitudinal MDCT images of 9 patients with 18 incidental fractures in the follow-up MDCT were retrospectively selected. The spine segmentation algorithm localised and identified the vertebrae T5-L5. Each vertebra was automatically segmented by using corresponding vertebra surface shape models that were adapted to the original images. Anterior, middle, and posterior height of each vertebra was automatically determined; the anterior-posterior ratio (APR) and middle-posterior ratio (MPR) were computed. As the gold standard, radiologists graded vertebral fractures from T5 to L5 according to the Genant classification in consensus. Using ROC analysis to differentiate vertebrae without versus with prevalent fracture, AUC values of 0.84 and 0.83 were obtained for APR and MPR, respectively (p < 0.001). Longitudinal changes in APR and MPR were significantly different between vertebrae without versus with incidental fracture (ΔAPR: -8.5 % ± 8.6 % versus -1.6 % ± 4.2 %, p = 0.002; ΔMPR: -11.4 % ± 7.7 % versus -1.2 % ± 1.6 %, p < 0.001). This prototype algorithm may support radiologists in reporting currently underdiagnosed osteoporotic vertebral fractures so that appropriate therapy can be initiated. circle This spine segmentation algorithm automatically localised, identified, and segmented the vertebrae in MDCT images.

    Serum undercarboxylated osteocalcin (ucOC) is an index of vitamin K nutritional status in treatment-naive postmenopausal osteoporotic women. The purpose of the present study was to reveal the association between vitamin K nutritional status and serum ucOC concentrations in postmenopausal osteoporotic women taking bisphosphonates. Eighty-six postmenopausal women with osteoporosis (age range: 47-90 years) initiated bisphosphonate treatment. Vitamin K nutritional status was evaluated using a simple vitamin K-intake questionnaire and serum ucOC concentrations were measured after 6 months of treatment. The patients were divided into two groups according to the simple vitamin K-intake questionnaire score: a low vitamin K-intake (score =40) group (n=19). There were no significant differences between the groups in baseline parameters including age, height, body weight, body mass index, serum alkaline phosphatase (ALP), urinary cross-linked N-terminal telopeptides of type I collagen (NTX), and changes in serum ALP and urinary NTX concentrations during the 6-month treatment period. However, the mean serum ucOC concentration after 6 months of treatment was significantly higher in the low vitamin K-intake group (2.79 ng/mL) than in the normal vitamin K-intake group (2.20 ng/mL). These results suggest that 78% of postmenopausal osteoporotic women treated with bisphosphonates may have vitamin K deficiency as indicated by low vitamin K-intake and high serum ucOC concentrations, despite having a similar reduction in bone turnover to women who have normal vitamin K-intake.

    Increased intake or supplementation of vitamin D is often recommended for normal bone health; however, its preventive effect on osteoporosis has not been fully evaluated. The aim of this review is to gather evidence of the efficacy of the optimization of vitamin D nutrition in preventing osteoporosis and osteoporotic fractures. PubMed was used for searching the relevant literature using the MeSH terms "Bone Density (limited to "human", "female", and "English" literature)" or "Fractures (limited to "human", "age ≥45 years", and "English" literature)", and "Vitamin D". The searches yielded 19 randomized controlled trials (RCTs), nine cohort studies, 19 case-control studies, 19 cross-sectional studies, and one meta-analysis. We attempted to answer three questions: 1) does increased vitamin D intake prevent bone loss in peri- and postmenopausal women?, 2) does increased vitamin D intake prevent osteoporotic fractures in the elderly?, and 3) does increased vitamin D in take positively affect peak bone mass attainment in young women? The answer to questions 1 and 2 is that a vitamin D intake of 10-17.5 μg/day (400-700 IU/day) or more is effective in preventing bone loss in late postmenopausal women and an intake of 17.5-20 μg/day (700-800 IU/day) or more together with a calcium supplement reduces the risk of osteoporotic fractures. For question 3, some lines of evidence support the negative effect of low vitamin D nutrition on the attainment of peak bone mass in young women. Further studies are needed to clarify the effect of vitamin D in this age group.
