Abstract
BACKGROUND Whether circulating sex hormones modulate mortality and cardiovascular disease (CVD) risk in aging men is controversial. PURPOSE To clarify associations of sex hormones with these outcomes. DATA SOURCES Systematic literature review to July 2019, with bridge searches to March 2024. STUDY SELECTION Prospective cohort studies of community-dwelling men with sex steroids measured using mass spectrometry and at least 5 years of follow-up. DATA EXTRACTION Independent variables were testosterone, sex hormone-binding globulin (SHBG), luteinizing hormone (LH), dihydrotestosterone (DHT), and estradiol concentrations. Primary outcomes were all-cause mortality, CVD death, and incident CVD events. Covariates included age, body mass index, marital status, alcohol consumption, smoking, physical activity, hypertension, diabetes, creatinine concentration, ratio of total to high-density lipoprotein cholesterol, and lipid medication use. DATA SYNTHESIS Nine studies provided individual participant data (IPD) (255 830 participant-years). Eleven studies provided summary estimates (n = 24 109). Two-stage random-effects IPD meta-analyses found that men with baseline testosterone concentrations below 7.4 nmol/L (<213 ng/dL), LH concentrations above 10 IU/L, or estradiol concentrations below 5.1 pmol/L had higher all-cause mortality, and those with testosterone concentrations below 5.3 nmol/L (<153 ng/dL) had higher CVD mortality risk. Lower SHBG concentration was associated with lower all-cause mortality (median for quintile 1 [Q1] vs. Q5, 20.6 vs. 68.3 nmol/L; adjusted hazard ratio [HR], 0.85 [95% CI, 0.77 to 0.95]) and lower CVD mortality (adjusted HR, 0.81 [CI, 0.65 to 1.00]). Men with lower baseline DHT concentrations had higher risk for all-cause mortality (median for Q1 vs. Q5, 0.69 vs. 2.45 nmol/L; adjusted HR, 1.19 [CI, 1.08 to 1.30]) and CVD mortality (adjusted HR, 1.29 [CI, 1.03 to 1.61]), and risk also increased with DHT concentrations above 2.45 nmol/L. Men with DHT concentrations below 0.59 nmol/L had increased risk for incident CVD events. LIMITATIONS Observational study design, heterogeneity among studies, and imputation of missing data. CONCLUSION Men with low testosterone, high LH, or very low estradiol concentrations had increased all-cause mortality. SHBG concentration was positively associated and DHT concentration was nonlinearly associated with all-cause and CVD mortality.

Clin Endocrinol (Oxf) 2024; 100:170-180. [PMID: 38059618 PMCID: PMC10952793 DOI: 10.1111/cen.14997] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/21/2023] [Revised: 10/22/2023] [Accepted: 11/16/2023] [Indexed: 12/08/2023]
Abstract
OBJECTIVE Prevalence of subclinical thyroid disease increases with age, but optimal detection and surveillance strategies remain unclear particularly for older men. We aimed to assess thyroid stimulating hormone (TSH) and free thyroxine (FT4) concentrations and their longitudinal changes, to determine the prevalence and incidence of subclinical thyroid dysfunction in older men. DESIGN, PARTICIPANTS AND MEASUREMENTS Longitudinal study of 994 community-dwelling men aged ≥70 years without known or current thyroid disease, with TSH and FT4 concentrations assessed at baseline and follow-up (after 8.7 ± 0.9 years). Factors associated with incident subclinical thyroid dysfunction were examined by logistic regression and receiver operating characteristic analyses. RESULTS At baseline, 85 men (8.6%) had subclinical hypothyroidism and 10 (1.0%) subclinical hyperthyroidism. Among 899 men euthyroid at baseline (mean age 75.0 ± 3.0 years), 713 (79.3%) remained euthyroid, 180 (20.0%) developed subclinical/overt hypothyroidism, and 6 (0.7%) subclinical/overt hyperthyroidism. Change in TSH correlated with baseline TSH (r = .16, p < .05). Change in FT4 correlated inversely with baseline FT4 (r = -0.35, p < .05). Only higher age and baseline TSH predicted progression from euthyroid to subclinical/overt hypothyroidism (fully-adjusted odds ratio [OR] per year=1.09, 95% confidence interval [CI] = 1.02-1.17, p = .006; per 2.7-fold increase in TSH OR = 65.4, CI = 31.9-134, p < .001). Baseline TSH concentration ≥2.34 mIU/L had 76% sensitivity and 77% specificity for predicting development of subclinical/overt hypothyroidism. CONCLUSIONS In older men TSH concentration increased over time, while FT4 concentration showed little change. Subclinical or overt hypothyroidism evolved in one fifth of initially euthyroid men, age and higher baseline TSH predicted this outcome. Increased surveillance for thyroid dysfunction may be justified in older men, especially those with high-normal TSH.

Abstract
OBJECTIVE To determine the prevalence of common mental disorders among older Australians included in the Health In Men Data Linkage Study and compare those with the results of the 2020-2021 National Study of Mental Health and Wellbeing (NSMHW). METHOD We used longitudinal record linkage to estimate the prevalence of mental disorders from age 65 years in a random sample of 38173 Australian men aged 65-85 years living in the Perth metropolitan region. Outcome was the proportion of participants affected by depressive episodes or dysthymia, bipolar disorder, anxiety disorder, psychotic disorder and alcohol use disorder. RESULTS Prevalence estimates for participants aged 65-69, 70-74, 75-79, 80-84 and ≥85 years were 0.9%, 2.0%, 3.6%, 5.8% and 12.6% for depressive, 0.2%, 0.3%, 0.4%, 0.4% and 0.7% for bipolar, 0.1%, 0.5%, 1.3%, 2.2%, 6.9% for anxiety, 0.2%, 0.4%, 0.5%, 0.4% and 0.6% for psychotic and 1.2%, 1.7%, 2.1%, 2.2% and 4.2% for alcohol use disorders. CONCLUSIONS In contrast to the NSMHW, our data indicate that the prevalence of depressive and anxiety disorders increases with age, particularly among the older old. We conclude that the NSMHW should not be relied upon to guide planning or policies to address the mental health needs of older Australians.

Exposure to low-level ambient air pollution and the relationship with lung and bladder cancer in older men, in Perth, Western Australia. Br J Cancer 2023; 129:1500-1509. [PMID: 37684355 PMCID: PMC10628106 DOI: 10.1038/s41416-023-02411-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2022] [Revised: 08/06/2023] [Accepted: 08/18/2023] [Indexed: 09/10/2023] Open
Abstract
BACKGROUND Air pollution is a cause of lung cancer and is associated with bladder cancer. However, the relationship between air pollution and these cancers in regions of low pollution is unclear. We investigated associations between fine particulate matter (PM2.5), nitrogen dioxide, and black carbon (BC), and both these cancers in a low-pollution city. METHODS A cohort of 11,679 men ≥65 years old in Perth (Western Australia) were followed from 1996-1999 until 2018. Pollutant concentrations, as a time-varying variable, were estimated at participants' residential addresses using land use regression models. Incident lung and bladder cancer were identified through the Western Australian Cancer Registry. Risks were estimated using Cox proportional-hazard models (age as the timescale), adjusting for smoking, socioeconomic status, and co-pollutants. RESULTS Lung cancer was associated with PM2.5 and BC in the adjusted single-pollutant models. A weak positive association was observed between ambient air pollution and squamous cell lung carcinoma but not lung adenocarcinoma. Positive associations were observed with bladder cancer, although these were not statistically significant. Associations were attenuated in two-pollutant models. CONCLUSION Low-level ambient air pollution is associated with lung, and possibly bladder, cancer among older men, suggesting there is no known safe level for air pollution as a carcinogen.

Paterson J, Trevenen M, Hill K, Almeida OP, Yeap BB, Golledge J, Hankey GJ, Flicker L. Balance and Strength Measures are Associated With Mortality in Older Men. J Am Med Dir Assoc 2023; 24:1527-1532.e2. [PMID: 37187326 DOI: 10.1016/j.jamda.2023.03.038] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2022] [Revised: 03/30/2023] [Accepted: 03/30/2023] [Indexed: 05/17/2023]
Abstract
OBJECTIVES As people age, rates of morbidity and mortality are heterogenous. Balance and strength performance may contribute to this, offering modifiable risk factors for mortality. We aimed to compare relationships of balance and strength performance with all-cause and cause-specific mortality. DESIGN The Health in Men Study, a cohort study, using wave 4 as baseline for analyses (2011-2013). SETTING AND PARTICIPANTS 1335 older men (>65 years old), initially recruited April 1996-January 1999 in Western Australia, were included. METHODS Physical tests included a strength (knee extension test) and balance measure (modified Balance Outcome Measure for Elder Rehabilitation (mBOOMER) Score), derived from baseline physical assessments. Outcome measures included all-cause, cardiovascular, and cancer mortality, ascertained via the WADLS death registry. Data were analyzed using Cox proportional hazards regression models (age as analysis time, adjusted for sociodemographic data, health behaviors, and conditions). RESULTS Four hundred seventy-three participants died before the end of follow-up (December 17, 2017). Better performance on both the mBOOMER score and knee extension test was associated with lower likelihood of all-cause [hazard ratio (HR) 0.83, 95% CI 0.80-0.87, and HR 0.96, 95% CI 0.95-0.98, respectively] and cardiovascular mortality (HR 0.82, 95% CI 0.77-0.87, and HR 0.96, 95% CI 0.94-0.98, respectively). Better mBOOMER score performance was associated with lower likelihood of cancer mortality (HR 0.90, 95% CI 0.83-0.98) only when including participants with prior cancer. CONCLUSIONS AND IMPLICATIONS In summary, this study demonstrates an association of poorer performance in both strength and balance with future all-cause and cardiovascular mortality. Notably, these results clarify the relationship of balance with cause-specific mortality, with balance equaling strength as a modifiable risk factor for mortality.

Abstract
BACKGROUND Various factors modulate circulating testosterone in men, affecting interpretation of testosterone measurements. PURPOSE To clarify factors associated with variations in sex hormone concentrations. DATA SOURCES Systematic literature searches (to July 2019). STUDY SELECTION Prospective cohort studies of community-dwelling men with total testosterone measured using mass spectrometry. DATA EXTRACTION Individual participant data (IPD) (9 studies; n = 21 074) and aggregate data (2 studies; n = 4075). Sociodemographic, lifestyle, and health factors and concentrations of total testosterone, sex hormone-binding globulin (SHBG), luteinizing hormone (LH), dihydrotestosterone, and estradiol were extracted. DATA SYNTHESIS Two-stage random-effects IPD meta-analyses found a nonlinear association of testosterone with age, with negligible change among men aged 17 to 70 years (change per SD increase about the midpoint, -0.27 nmol/L [-7.8 ng/dL] [CI, -0.71 to 0.18 nmol/L {-20.5 to 5.2 ng/dL}]) and decreasing testosterone levels with age for men older than 70 years (-1.55 nmol/L [-44.7 ng/dL] [CI, -2.05 to -1.06 nmol/L {-59.1 to -30.6 ng/dL}]). Testosterone was inversely associated with body mass index (BMI) (change per SD increase, -2.42 nmol/L [-69.7 ng/dL] [CI, -2.70 to -2.13 nmol/L {-77.8 to -61.4 ng/dL}]). Testosterone concentrations were lower for men who were married (mean difference, -0.57 nmol/L [-16.4 ng/dL] [CI, -0.89 to -0.26 nmol/L {-25.6 to -7.5 ng/dL}]); undertook at most 75 minutes of vigorous physical activity per week (-0.51 nmol/L [-14.7 ng/dL] [CI, -0.90 to -0.13 nmol/L {-25.9 to -3.7 ng/dL}]); were former smokers (-0.34 nmol/L [-9.8 ng/dL] [CI, -0.55 to -0.12 nmol/L {-15.9 to -3.5 ng/dL}]); or had hypertension (-0.53 nmol/L [-15.3 ng/dL] [CI, -0.82 to -0.24 nmol/L {-23.6 to -6.9 ng/dL}]), cardiovascular disease (-0.35 nmol/L [-10.1 ng/dL] [CI, -0.55 to -0.15 nmol/L {-15.9 to -4.3 ng/dL}]), cancer (-1.39 nmol/L [-40.1 ng/dL] [CI, -1.79 to -0.99 nmol/L {-51.6 to -28.5 ng/dL}]), or diabetes (-1.43 nmol/L [-41.2 ng/dL] [CI, -1.65 to -1.22 nmol/L {-47.6 to -35.2 ng/dL}]). Sex hormone-binding globulin was directly associated with age and inversely associated with BMI. Luteinizing hormone was directly associated with age in men older than 70 years. LIMITATION Cross-sectional analysis, heterogeneity between studies and in timing of blood sampling, and imputation for missing data. CONCLUSION Multiple factors are associated with variation in male testosterone, SHBG, and LH concentrations. Reduced testosterone and increased LH concentrations may indicate impaired testicular function after age 70 years. Interpretation of individual testosterone measurements should account particularly for age older than 70 years, obesity, diabetes, and cancer.

Healthy lifestyles are associated with better vitamin D status in community-dwelling older men: The Health In Men Study (HIMS). Clin Endocrinol (Oxf) 2023; 99:165-173. [PMID: 37165475 PMCID: PMC10952998 DOI: 10.1111/cen.14926] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/29/2023] [Revised: 04/23/2023] [Accepted: 04/24/2023] [Indexed: 05/12/2023]
Abstract
OBJECTIVE Older people are more prone to vitamin D deficiency than younger populations. Individual lifestyle factors have been associated with vitamin D status. We examined the influence of a combination of lifestyle factors on vitamin D status in older men. PARTICIPANTS AND MEASUREMENTS In a population-based cohort study of older men (age ≥65 years), a lifestyle score was calculated from eight prudent health-related behaviours (smoking, exercise, alcohol, fish and meat consumption, adding salt, milk choices and obesity) collected via questionnaire at baseline. Blood samples were collected 5 years afterwards to measure plasma 25-hydroxyvitamin D (25OHD) levels. Associations between lifestyles and the likelihood of having plasma 25OHD levels of ≥75 versus <75 nmol/L and ≥50 versus <50 nmol/L were tested using logistic regression models. RESULTS Of the 2717 men analysed, mean plasma 25OHD was 69.0 ± 23.5 nmol/L, with 20.7% having plasma 25OHD <50 nmol/L. Men engaging in ≥4 healthy lifestyle behaviours had 20% higher odds of plasma 25OHD ≥75 nmol/L (adjusted OR = 1.20, 95% CI: 1.01-1.45) compared to those with <4 healthy behaviours. No association was found for 25OHD ≥50 nmol/L. Higher physical activity was the only individual component significantly associated with vitamin D sufficiency (highest vs. lowest quintiles of physical activity, adjusted OR = 2.01, 95% CI: 1.47-2.74 for 25OHD ≥50 nmol/L, adjusted OR = 2.35, 95% CI: 1.81-3.06 for 25OHD ≥75 nmol/L). CONCLUSION Multiple healthy lifestyle behaviours are associated with better vitamin D status in older men. Further work is needed to determine the effects of promoting healthy lifestyle behaviours, including physical activity, on vitamin D sufficiency.

Long-term exposure to low-concentration PM 2.5 and heart disease in older men in Perth, Australia: The Health in Men Study. Environ Epidemiol 2023; 7:e255. [PMID: 37545811 PMCID: PMC10402964 DOI: 10.1097/ee9.0000000000000255] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2023] [Accepted: 05/31/2023] [Indexed: 08/08/2023] Open
Abstract
Exposure to particulate matter with an aerodynamic diameter less than or equal to 2.5 μm (PM2.5) is associated with increased risk of heart disease, but less is known about the relationship at low concentrations. This study aimed to determine the dose-response relationship between long-term PM2.5 exposure and risk of incident ischemic heart disease (IHD), incident heart failure (HF), and incident atrial fibrillation (AF) in older men living in a region with relatively low ambient air pollution. Methods PM2.5 exposure was estimated for 11,249 older adult males who resided in Perth, Western Australia and were recruited from 1996 to 1999. Participants were followed until 2018 for the HF and AF outcomes, and until 2017 for IHD. Cox-proportional hazards models, using age as the analysis time, and adjusting for demographic and lifestyle factors were used. PM2.5 was entered as a restricted cubic spline to model nonlinearity. Results We observed a mean PM2.5 concentration of 4.95 μg/m3 (SD 1.68 μg/m3) in the first year of recruitment. After excluding participants with preexisting disease and adjusting for demographic and lifestyle factors, PM2.5 exposure was associated with a trend toward increased incidence of IHD, HF, and AF, but none were statistically significant. At a PM2.5 concentration of 7 μg/m3 the hazard ratio for incident IHD was 1.04 (95% confidence interval [CI] = 0.86, 1.25) compared with the reference category of 1 μg/m3. Conclusions We did not observe a significant association between long-term exposure to low-concentration PM2.5 air pollution and IHD, HF, or AF.

Abstract
Cancer has been associated with lower risk of dementia, although methodological issues raise concerns about the validity of this association. We recruited 31,080 men aged 65-85 years who were free of cancer and dementia, and followed them for up to 22 years. We used health record linkage to identify incident cases of cancer and dementia, and split time span to investigate this association. 18,693 (60.1%) and 6897 (22.2%) participants developed cancer and dementia during follow-up. The hazard ratio (HR) of dementia associated with cancer was 1.13 (95% CI = 1.07, 1.20) and dropped to 0.85 (95% CI = 0.80, 0.91) when 449 participants who developed dementia within 2 years were excluded. The diagnosis of cancer seems to facilitate the early detection of dementia cases. Older participants who survive cancer for 2 or more years have lower risk of receiving the diagnosis of dementia over time. The factors that mediate this association remain unclear.

Abstract
OBJECTIVES This study is designed to determine if hearing loss is associated with increased risk of frailty in later life. DESIGN A prospective cohort study. SETTING AND PARTICIPANTS We retrieved data of a community sample of men aged 70 years and above living in the metropolitan region of Perth, Western Australia. 3,285 participants who were free of frailty at the beginning of the study were followed for up to 17 years. Data were retrieved from the Health in Men Study (HIMS) and the Western Australian Data Linkage System (WADLS). MEASUREMENTS Hearing loss was defined by self-report or by diagnosis recorded in the WADLS. Incident frailty was assessed using the Hospital Frailty Risk Score (HFRS). RESULTS A total of 2,348 (71.5%) men developed frailty during follow up. The adjusted hazard ratio was 1.03 (95% CI: 0.95-1.12). The majority of the participants became frail by age 90 regardless of hearing condition. The time point where half of the group become frail was delayed by 14.4 months for men without hearing loss compared with hearing impaired men. CONCLUSIONS Hearing loss is not associated with incident frailty in men aged 70 years or older when frailty was measured by HFRS. However, this statistically non-significant result could be due to the low sensitivity of study measures. Also, we found a trend that men with hearing loss were more likely to develop frailty compared with their normal-hearing peers, suggesting a potential association between hearing loss and frailty.

Abstract
BACKGROUND In areas with moderate to severe air pollution, pollutant concentrations are associated with dementia risk. It is unclear whether the same relationship is present in regions with lower ambient air pollution. OBJECTIVE To determine whether exposure to air pollution is associated with risk of incident dementia in general, and Alzheimer's disease and vascular dementia in particular, in older men living in a relatively low ambient air pollution region. METHODS The cohort comprised 11,243 men residing in Perth, Australia. Participants were aged ≥65 years and free of a dementia diagnosis at time of recruitment in 1996-1999. Incident dementia was identified from recruitment to 2018 via ICD diagnosis codes and subsequent study waves. Concentrations for three air pollutants, nitrogen dioxide (NO2), fine particulate matter less than 2.5 μm in diameter (PM2.5), and black carbon (BC) were estimated at participants' home addresses using land-use regression models. We used Cox proportional hazards regression models adjusting for smoking status, physical activity, BMI, education, and socio-economic status. RESULTS Of 3053 (27.2%) incident cases of dementia, 1670 (54.7%) and 355 (11.6%) had documented Alzheimer's disease and vascular dementia. The average concentration of NO2 was 13.5 (SD 4.4) μg/m3, of PM2.5 was 4.54 (SD 1.6) μg/m3 and of BC was 0.97 (SD 0.29) ×10-5 m-1. None of the air pollutants were associated with incident dementia or Alzheimer's disease. In the unadjusted model, increased exposure to PM2.5 was associated with an increased risk of vascular dementia (for a 5 μg/m3 increase: HR 1.62, 95% CI 1.13, 2.31). However, this association was attenuated following adjustment for confounders (HR 1.39, 95% CI 0.93, 2.08). NO2 and BC were not associated with vascular dementia incidence. DISCUSSION Exposure to air pollution is not associated with increased risk of incident dementia in older men living in a region with relatively low ambient air pollution.

Abstract
OBJECTIVE Few prospective studies have assessed whether individuals with subclinical thyroid dysfunction are more likely to develop diabetes, with conflicting results. In this study, we conducted a systematic review of the literature and an individual participant data analysis of multiple prospective cohorts to investigate the association between subclinical thyroid dysfunction and incident diabetes. METHODS We performed a systematic review of the literature in Medline, Embase, and the Cochrane Library from inception to February 11, 2022. A two-stage individual participant data analysis was conducted to compare participants with subclinical hypothyroidism and subclinical hyperthyroidism vs euthyroidism at baseline and the adjusted risk of developing diabetes at follow-up. RESULTS Among 61 178 adults from 18 studies, 49% were females, mean age was 58 years, and mean follow-up time was 8.2 years. At the last available follow-up, there was no association between subclinical hypothyroidism and incidence of diabetes (odds ratio (OR) = 1.02, 95% CI: 0.88-1.17, I2 = 0%) or subclinical hyperthyroidism and incidence of diabetes (OR = 1.03, 95% CI: 0.82-1.30, I2 = 0%), in age- and sex-adjusted analyses. Time-to-event analysis showed similar results (hazard ratio for subclinical hypothyroidism: 0.98, 95% CI: 0.87-1.11; hazard ratio for subclinical hyperthyroidism: 1.07, 95% CI: 0.88-1.29). The results were robust in all sub-group and sensitivity analyses. CONCLUSIONS This is the largest systematic review and individual participant data analysis to date investigating the prospective association between subclinical thyroid dysfunction and diabetes. We did not find an association between subclinical thyroid dysfunction and incident diabetes. Our results do not support screening patients with subclinical thyroid dysfunction for diabetes. SIGNIFICANCE STATEMENT Evidence is conflicting regarding whether an association exists between subclinical thyroid dysfunction and incident diabetes. We therefore aimed to investigate whether individuals with subclinical thyroid dysfunction are more prone to develop diabetes in the long run as compared to euthyroid individuals. We included data from 18 international cohort studies with 61 178 adults and a mean follow-up time of 8.2 years. We did not find an association between subclinical hypothyroidism or subclinical hyperthyroidism at baseline and incident diabetes at follow-up. Our results have clinical implications as they neither support screening patients with subclinical thyroid dysfunction for diabetes nor treating them in the hope of preventing diabetes in the future.

[PMID: 36276719 PMCID: PMC9578981 DOI: 10.1016/j.heliyon.2022.e10905] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2022] [Revised: 05/22/2022] [Accepted: 09/27/2022] [Indexed: 11/06/2022] Open
Abstract
Background Acute exposure to ambient air pollution even at low concentrations has been associated with increased hospitalisation for respiratory diseases but the effects of long-term exposure are less certain. In this study, we investigated the associations between long-term exposures to PM2.5, PM2.5 absorbance and NO2 and hospitalisation for asthma, chronic obstructive pulmonary disease and pneumonia in a cohort of older men living in Perth, Western Australia, a city where the levels of air pollutants are well below the world standards. Materials and methods The study population of 11,156 men with no prior hospitalisation for respiratory disease was drawn from the Health in Men Study (HIMS) cohort of men aged >65 years living in Perth, Western Australia between 1996-1999. PM2.5, PM2.5 absorbance (PM2.5a) and NO2 were measured across the Perth metropolitan area over three seasons in 2012. Land use regression (LUR) models were used to estimate annual concentrations of PM2.5, PM2.5 absorbance and NO2 at the residential address of each participant from inception (1996) to 2015. Hospitalisation for respiratory disease between inception and 2015 was ascertained using the Western Australian Data Linkage System. The association between exposure to air pollution with hospitalisation for respiratory disease was examined using Cox regression analysis. Results No statistically significant associations were observed in the fully adjusted models. However, positive associations were observed with first hospitalisation for pneumonia (HR 1.08, 95% CI: 1.01–1.16) when adjusted for age, year of enrolment, smoking status, education, BMI and physical activity. Conclusions In this longitudinal study of older men we found no evidence of associations between increased long-term exposure to low-level air pollution with increased risk of hospitalisation for respiratory diseases in Perth, Australia. More studies on respiratory morbidity associated with exposure to low levels of air pollution are needed for more comprehensive understanding of the overall risk.

The Hospital Frailty Risk Score Identifies Fewer Cases of Frailty in a Community-Based Cohort of Older Men Than the FRAIL Scale and Frailty Index. J Am Med Dir Assoc 2022; 23:1348-1353.e8. [PMID: 34740563 DOI: 10.1016/j.jamda.2021.09.033] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2021] [Revised: 09/23/2021] [Accepted: 09/24/2021] [Indexed: 12/24/2022]
Abstract
OBJECTIVES The recently developed Hospital Frailty Risk Score (HFRS) allows ascertainment of frailty from administrative data. We aimed to compare the HFRS against the widely used FRAIL Scale and Frailty Index. DESIGN Population-based cohort study linked to Western Australian Hospital Morbidity Data Collection and Death Registrations. SETTING AND PARTICIPANTS The Health in Men Study with frailty determined at Wave 2 (2001/2004), mortality in the 1-year period following Wave 2, and disability at Wave 3 (2008). Participants were 4228 community-based men aged ≥75 years, followed until Wave 3. MEASUREMENTS We used multivariable regression to determine the association between each frailty measure and outcomes of length of stay (LOS), death, and disability. We also determined if the additional cases of frailty identified by one measure over the other was associated with these outcomes. RESULTS Of 4228 men studied, the HFRS (n = 689) identified fewer men as frail than the FRAIL Scale (n = 1648) and Frailty Index (n = 1820). In the fully adjusted models, all 3 frailty measures were associated with longer LOS and mortality, whereas only the FRAIL Scale and Frailty Index were significantly associated with disability. The additional cases of frailty identified by the FRAIL Scale and Frailty Index had longer LOS and greater risks of death and disability. The fully adjusted hazard ratio for death among the additional cases of frailty identified by the FRAIL Scale (compared to being not frail on both HFRS and FRAIL Scale) was 2.14 (95% CI 1.48-3.08). CONCLUSIONS AND IMPLICATIONS The HFRS is associated with adverse outcomes. However, it identified approximately 60% fewer men who were frail than the FRAIL Scale and Frailty Index, and the additional cases identified were also at high risks of adverse outcomes. Users of the HFRS should be aware of the differences with other frailty measures.

Bone Turnover Markers Including Undercarboxylated Osteocalcin Are Associated With Mortality Risk in Older Men. J Bone Miner Res 2022; 37:1464-1472. [PMID: 35689459 PMCID: PMC9540459 DOI: 10.1002/jbmr.4631] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/10/2021] [Revised: 06/05/2022] [Accepted: 06/09/2022] [Indexed: 11/25/2022]
Abstract
Osteocalcin in its undercarboxylated form (ucOC) may influence diabetes risk; however, its relationship with all-cause and cause-specific mortality is unclear. Whether other bone turnover markers (BTMs) are associated with mortality risk differently from ucOC also remains uncertain. Our aim was to determine associations of serum ucOC with all-cause and cause-specific mortality and compare these with the corresponding associations of serum total osteocalcin (TOC), procollagen type I N-propeptide (PINP), and collagen type 1 C-terminal cross-linked telopeptide (CTX) in older men. We conducted a prospective cohort study of 3871 community-dwelling men, aged 77.0 ± 3.6 years at baseline, followed for a median of 12.3 years. Exposure variables were ucOC, TOC, PINP, and CTX concentrations assayed in serum. Outcomes were incidence of all deaths and deaths due to cardiovascular disease (CVD) or cancer, ascertained using death registry data. Cox regression analyses adjusted for cardiovascular risk factors and prevalent CVD and for prevalent cancer in analyses of cancer-related mortality. Higher concentrations of ucOC, PINP, and CTX were associated with all-cause mortality (hazard ratio [HR] per 1 standard deviation increase: ucOC 1.12, 95% confidence interval [CI] 1.06-1.18, p < 0.001; PINP HR = 1.06, 95% CI 1.01-1.11, p = 0.009; CTX HR = 1.13, 95% CI 1.08-1.19, p < 0.001), but TOC was not associated. Similar results were found after excluding men with an incident fracture during follow-up. Higher ucOC and CTX were associated with CVD mortality (ucOC HR per 1 SD increase 1.13, 95% CI 1.05-1.22, p = 0.001; CTX HR = 1.12, 95% CI 1.04-1.20, p = 0.003), but this result was not significant in competing risks analysis. Higher CTX was also associated with cancer mortality (HR = 1.12, 95% CI 1.01-1.23, p = 0.024). In conclusion, in older men, higher bone turnover, assessed by BTMs including ucOC, is a biomarker for all-cause mortality risk. Undercarboxylated osteocalcin was a more informative biomarker for this outcome than TOC. Higher CTX was associated with all-cause and cancer-related mortality. Further evaluation of causality and potential underlying mechanisms is warranted. © 2022 The Authors.

Disrupted sleep and risk of depression in later life: A prospective cohort study with extended follow up and a systematic review and meta-analysis. J Affect Disord 2022; 309:314-323.

Abstract
BACKGROUND Sleep difficulties increase the risk of current and future depression, but it is unclear if this relationship is causal. METHODS Prospective cohort study of a community sample of men aged 70-89 years followed for up to 17 years. Initial assessments occurred between 2001 and 2004. Participants were followed until death or 31 December 2018. Patient Health Questionnaire (PHQ-9) ≥ 10 at subsequent waves of assessments (every 2-3 years) or the recorded diagnosis of a depressive disorder in the Western Australian Data Linkage System marked the onset of depression during follow up. We excluded from follow up men with prevalent depression. The systematic review of longitudinal studies examining the association between disrupted sleep and depression in later life followed PRISMA guidelines. RESULTS 3441 of 5547 older men reported sleep difficulties at study entry. Current or past depression affected 437 of 5547 participants. Of the 4561 older men free of depression, 2693 reported sleep difficulties. The hazard ratio (HR) of incident depression among participants with sleep problems was 1.67 (95%CI = 1.39-2.00). Statistical adjustments for age, place of birth, education, smoking and physical frailty did not change the effect-size of this association. The systematic review identified another 14 studies, and the meta-analysis yielded an overall risk ratio of depression of 1.82 (95%CI = 1.69-1.97), although the overall quality of available evidence was sub-optimal. CONCLUSIONS Disrupted sleep increases the risk of depression in later life and this seems unlikely to be due to reverse causality. Older adults with sleep difficulties are legitimate targets of interventions to prevent depression.

Abstract
Introduction Frailty is associated with an increased risk of death and morbid events. Frail individuals are known to have multiple comorbidities which are often associated with polypharmacy. Whilst a relationship between polypharmacy and frailty has been demonstrated, it is not clear if there is an independent relationship between frailty and medication harm. Aims This scoping review aimed to identify and critically appraise studies evaluating medication harm in patients with frailty. Methods PubMed, EMBASE, CINAHL and Cochrane databases were searched from inception until 1 February 2021 using key search terms that are synonymous with frailty (such as frail and frail elderly) and medication harm (such as adverse drug events and adverse drug reactions). To be included, studies must have identified medication harm as a primary or secondary outcome measure, and used a frailty assessment tool to determine frailty, or clearly defined how frailty was assessed. Data were narratively synthesised and presented in tables. The checklist from the Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies from the National Heart, Lung, and Blood Institute was used to assess the quality and risk of bias of studies that met the inclusion criteria. Results Of 2685 retrieved abstracts, 24 underwent full-text review and nine studies met the inclusion criteria. Three studies were retrospective cohort studies, and six were prospective observational studies. Six studies comprised two distinct groups of frail and non-frail individuals, and the remaining three studies evaluated medication harm in an entirely frail population. Seven studies used validated frailty tools such as the Clinical Frailty Scale, Fried Frailty Index, and Fried Frailty Phenotype. Two studies measured frailty using self-defined criteria. Overall, frail individuals were at risk of medication harm with rates ranging between 18.7 and 77% across the nine studies. However, whether frailty is an independent predictor of medication harm remains uncertain, as this was only evaluated in one study. The risk of bias assessment identified limitations in methods and reporting with all nine studies. Conclusion This scoping review identified nine studies evaluating medication harm in frail patients. However, all were limited by the methodological quality and inadequate reporting of study factors. There are few high-quality studies that described a relationship between medication harm and frailty. More robust studies are required that examine the independent relationship between frailty and medication harm, after adjusting for all possible confounders and in particular polypharmacy.

Abstract
BACKGROUND Older adults are at high risk of medication-related hospitalizations. Frailty is a phenotype commonly observed in older people due to declining physiological functions. AIM To examine the association of frailty with medication-related hospitalization among community dwelling older men. METHODS A prospective observational cohort study was conducted among community dwelling older men (mean age 75.6 years SD 5.9) from Western Australia (4324) who participated in the Health in Men Study. Participants were followed-up at 12 and 24 months to determine adverse drug event-related hospitalization, hospitalizations for other causes and mortality. RESULTS AND DISCUSSION The prevalence of frailty was 13.2%. At baseline, frailty was associated with exposure to polypharmacy, potentially inappropriate medication use and potential adverse drug-drug interactions with unadjusted odds ratios; [4.13 (3.48-4.89) P < 0.001], [2.46 (1.91-3.17) P < 0.001], [3.85 (3.03-4.90) P < 0.001], respectively. In unadjusted models, frail men were more likely to have non-accidental falls [OR 3.16 (2.51-3.99) P < 0.001], acute kidney injury [OR 3.37 (2.35-4.82) P < 0.001], ADE-related hospitalizations at 12 months [OR 6.83 (4.91-9.51)] and non-ADE-related hospitalizations [OR 2.63 (2.01-3.45)], or to be dead at 12 months [OR 2.97 (1.79-4.92)] and at 24 months [OR 3.14 (2.28-4.33)] when compared with non-frail men. After adjusting for age, living alone, cognitive decline, smoking status and comorbidity, frailty remained associated with ADE-related hospitalization [OR 3.60 (2.41-5.37)], non-ADE-related hospitalizations [OR 1.74 (1.29-2.36)] and death [OR 1.67 (1.15-2.41)]. CONCLUSION The study suggests that frailty is a predictor of medication-related harm with poorer clinical outcomes including mortality.

Abstract
OBJECTIVE To determine if hearing loss is associated with increased risk of frailty in later life. STUDY DESIGN Cross-sectional study of a community sample of 4,004 men aged 70 years and above living in the metropolitan region of Perth, Western Australia. Data were retrieved from the Health in Men Study (HIMS) and the Western Australian Data Linkage System (WADLS). Frailty was assessed using the FRAIL scale and the Frailty Index. Hearing loss was defined by self-report or by diagnosis recorded in the WADLS. We also collected demographic, lifestyle and social support information. MAIN OUTCOME MEASURES Frailty was assessed using the FRAIL scale and the Frailty Index. RESULTS The prevalence of frailty in the sample population was 16.1% and 25.4% when assessed using the FRAIL scale and the Frailty Index respectively. After adjusting for participant demographic, lifestyle and social factors, hearing loss was significantly associated with the prevalence of frailty when diagnosed by either measure (FRAIL scale: odds ratio [OR] 1.59, 95 CI% 1.32 to 1.91; Frailty Index: OR 1.76, 95 CI% 1.50 to 2.05). The proportion of men with hearing loss increased with increasing severity of frailty. CONCLUSION Hearing loss is associated with increased prevalence of frailty in older men when assessed using the FRAIL scale and the Frailty Index. Future longitudinal studies using objective measures of hearing will be helpful in determining if this association is likely to be causal.

Abstract
Addressing midlife hearing loss could prevent up to 9% of new cases of dementia, the highest of any potentially modifiable risk factor identified in the 2017 commissioned report in The Lancet. In Australia, hearing loss is the second-most common chronic health condition in older people, affecting 74% of people aged over 70. Estimates indicate that people with severe hearing loss are up to 5-times more likely to develop dementia, but these estimates vary between studies due to methodological limitations. Using data from the Sydney Memory and Aging Study, in which 1,037 Australian men and women aged between 70 and 90 years were enrolled and completed biennial assessments from 2005-2017, investigations between hearing loss and baseline cognitive performance as well as longitudinal risk of neurocognitive disorder were undertaken. Individuals who reported moderate-to-severe hearing difficulties had poorer cognitive performances in the domains of Attention/Processing Speed and Visuospatial Ability, and on an overall index of Global Cognition, and had a 1.5-times greater risk for the neurocognitive disorder during 6-years' follow-up. Hearing loss independently predicted risk for MCI but not dementia. The presence of hearing loss is an important consideration for neuropsychological case formulation in older adults with cognitive impairment. Hearing loss may increase cognitive load, resulting in observable cognitive impairment on neuropsychological testing. Individuals with hearing loss who demonstrate impairment in non-amnestic domains may experience benefits from the provision of hearing devices; This study provides support for a randomized control trial of hearing devices for improvement of cognitive function in this group.

Kallistatin limits abdominal aortic aneurysm by attenuating generation of reactive oxygen species and apoptosis. Sci Rep 2021; 11:17451. [PMID: 34465809 PMCID: PMC8408144 DOI: 10.1038/s41598-021-97042-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2021] [Accepted: 08/20/2021] [Indexed: 11/09/2022] Open
Abstract
Inflammation, vascular smooth muscle cell apoptosis and oxidative stress are believed to play important roles in abdominal aortic aneurysm (AAA) pathogenesis. Human kallistatin (KAL; gene SERPINA4) is a serine proteinase inhibitor previously shown to inhibit inflammation, apoptosis and oxidative stress. The aim of this study was to investigate the role of KAL in AAA through studies in experimental mouse models and patients. Serum KAL concentration was negatively associated with the diagnosis and growth of human AAA. Transgenic overexpression of the human KAL gene (KS-Tg) or administration of recombinant human KAL (rhKAL) inhibited AAA in the calcium phosphate (CaPO4) and subcutaneous angiotensin II (AngII) infusion mouse models. Upregulation of KAL in both models resulted in reduction in the severity of aortic elastin degradation, reduced markers of oxidative stress and less vascular smooth muscle apoptosis within the aorta. Administration of rhKAL to vascular smooth muscle cells incubated in the presence of AngII or in human AAA thrombus-conditioned media reduced apoptosis and downregulated markers of oxidative stress. These effects of KAL were associated with upregulation of Sirtuin 1 activity within the aortas of both KS-Tg mice and rodents receiving rhKAL. These results suggest KAL-Sirtuin 1 signalling limits aortic wall remodelling and aneurysm development through reductions in oxidative stress and vascular smooth muscle cell apoptosis. Upregulating KAL may be a novel therapeutic strategy for AAA.

Abstract
CONTEXT The osteoblast-derived polypeptide, osteocalcin (OC), has been associated with lower risk of type 2 diabetes and metabolic syndrome (MetS) in several epidemiological studies. Animal studies have indicated the undercarboxylated form of OC (ucOC) drives its association with metabolic outcomes. OBJECTIVE We compared associations of ucOC and carboxylated OC (cOC) with MetS and its components in older men. METHODS A cross-sectional analysis of 2575 men aged ≥70 years and older resident in Perth, Western Australia. ucOC was assayed using a hydroxyapatite-binding method, and cOC calculated by subtracting ucOC from total OC. Main outcome measures were MetS and its components. RESULTS Both lower serum ucOC and cOC levels, and the proportion of cOC (%cOC) were associated with less favorable metabolic parameters (higher waist circumference, triglyceride, glucose, blood pressure, and lower high-density lipoprotein cholesterol), whereas inverse associations were found with %ucOC. Men in the lowest quintile of ucOC had higher risk of MetS compared to men in the highest quintile (Q1 ≤ 7.7 vs Q5 > 13.8 ng/mL; OR = 2.4; 95% CI, 1.8-3.2). Men in the lowest quintile of cOC had higher risk of MetS compared to those in the highest quintile (≤ 5.8 vs > 13.0 ng/mL; OR = 2.4; 95% CI, 1.8-3.2). CONCLUSION Lower concentrations of serum ucOC or cOC were associated with less favorable metabolic parameters and a higher risk of MetS. In contrast, a lower proportion of ucOC was associated with better metabolic parameters and lower MetS risk. Further research is warranted to determine whether ucOC and cOC are suitable biomarkers for cardiometabolic risk in men.

U-Shaped Relationship of Leukocyte Telomere Length With All-Cause and Cancer-Related Mortality in Older Men. J Gerontol A Biol Sci Med Sci 2021; 76:164-171.

Abstract
BACKGROUND Telomeres are essential DNA-protein complexes whose attrition results in cellular dysfunction and senescence. Leukocyte telomere length (LTL) correlates with tissue telomere length, representing a biomarker for biological age. However, its predictive value for mortality risk, and for cardiovascular versus cancer deaths, in older adults remains uncertain. METHOD We studied 3608 community-dwelling men aged 77.0 ± 3.6 years. Leukocyte telomere length was measured using multiplex quantitative PCR, expressed as amount of telomeric DNA relative to single-copy control gene (T/S ratio). Deaths from any cause, cardiovascular disease (CVD), and cancer were ascertained using data linkage. Curve fitting used restricted cubic splines and Cox regression analyses adjusted for age, cardiometabolic risk factors, and prevalent disease. RESULTS There was a U-shaped association of LTL with all-cause mortality. Men with T/S ratio in the middle quartiles had lower mortality (quartiles, Q2 vs Q1, hazard ratio [HR] = 0.86, 95% confidence interval [CI] 0.77-0.97, p = .012; Q3 vs Q1 HR = 0.88, CI 0.79-0.99, p = .032). There was no association of LTL with CVD mortality. There was a U-shaped association of LTL with cancer mortality. Men with LTL in the middle quartiles had lower risk of cancer death (Q2 vs Q1, HR = 0.73, CI 0.59-0.90, p = .004; Q3 vs Q1, HR = 0.75, CI 0.61-0.92, p = .007). CONCLUSIONS In older men, both shorter and longer LTL are associated with all-cause mortality. A similar U-shaped association was seen with cancer deaths, with no association found for cardiovascular deaths. Further research is warranted to explore the prognostic utility of LTL in ageing.

Long-term exposure to outdoor air pollution and risk factors for cardiovascular disease within a cohort of older men in Perth. PLoS One 2021; 16:e0248931. [PMID: 33780497 PMCID: PMC8006998 DOI: 10.1371/journal.pone.0248931] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2020] [Accepted: 03/08/2021] [Indexed: 11/24/2022] Open
Abstract
While there is clear evidence that high levels of pollution are associated with increased all-cause mortality and cardiovascular mortality and morbidity, the biological mechanisms that would explain this association are less understood. We examined the association between long-term exposure to air pollutants and risk factors associated with cardiovascular disease. Air pollutant concentrations were estimated at place of residence for cohort members in the Western Australian Centre for Health and Ageing Health in Men Study. Blood samples and blood pressure measures were taken for a cohort of 4249 men aged 70 years and above between 2001 and 2004. We examined the association between 1-year average pollutant concentrations with blood pressure, cholesterol, triglycerides, C-reactive protein, and total homocysteine. Linear regression analyses were carried out, with adjustment for confounding, as well as an assessment of potential effect modification. The four pollutants examined were fine particulate matter, black carbon (BC), nitrogen dioxide, and nitrogen oxides. We found that a 2.25 μg/m3 higher exposure to fine particulate matter was associated with a 1.1 percent lower high-density cholesterol (95% confidence interval: -2.4 to 0.1) and 4.0 percent higher serum triglycerides (95% confidence interval: 1.5 to 6.6). Effect modification of these associations by diabetes history was apparent. We found no evidence of an association between any of the remaining risk factors or biomarkers with measures of outdoor air pollution. These findings indicate that long-term PM2.5 exposure is associated with elevated serum triglycerides and decreased HDL cholesterol. This requires further investigation to determine the reasons for this association.

Abstract
Background The Health In Men Study (HIMS) has been collecting data on risk factors and health events for the past 25 years in a large community-representative sample of older men. This paper summarises key-findings of the study about depression in later life. Methods Narrative review of selected HIMS studies published over the past 15 years describing risk factors associated with prevalent and incident depression in older men, as well as clinical outcomes associated with depression. Results Data from HIMS showed that cardiovascular diseases and risk factors are associated with increased risk of depression, but this association is neither specific nor causative. Findings from HIMS are not supportive of the vascular hypothesis of depression in later life. Studies investigating lifestyle have generated risk tables capable of guiding risk reduction strategies. Other potentially modifiable risk factors associated with depression in the HIMS cohort included abnormal allostatic inflammatory response, high plasma homocysteine and low testosterone. The results from HIMS also showed that depression is most likely a prodromal manifestation of dementia rather that a true risk factor, but it increases frailty and mortality. The association between depression and suicide in older men is largely mediated by deteriorating health and increasing frailty. Conclusion HIMS has contributed to advance knowledge about risk factors associated with depression, as well as the health consequences of depression in older men. The study is ongoing and the investigators welcome the opportunity to share data with colleagues who are interested in the health of older people.

Abstract
INTRODUCTION Fractures are common and disabling health events, particularly later in life. The presence of clinically significant depressive symptoms has been associated with increased risk of fractures, and we designed the present study to clarify if this association is likely to be causal or due to the confounding effect of measures associated with both fractures and depression. METHOD Cohort study of a community-derived sample of 4224 men aged 70 to 88 years at the start of the follow-up period of up to 17 years. Clinically significant symptoms of depression were defined as a recorded diagnosis of depressive episode in the Western Australian Data Linkage System (WADLS) or by a total score of 7 or greater on the 15-item Geriatric Depression Scale. Health contacts associated with fractures were retrieved from WADLS. Other measures included age, past history of fractures, education, smoking, frailty, poor vision, falls, medications, and the concentration of vitamin D, homocysteine, hsCRP and testosterone. Death was considered a competing risk for fractures. RESULTS 911 (21.6%) participants had a bone fracture during follow-up. After adjustment for multiple potential confounders, past and current depression were associated with an increase in the risk of novel fractures; respective odds ratios were 1.41 (95%CI = 1.03, 1.93) and 1.64 (95%CI = 1.20, 2.25). Parsimonious competing risk regression showed that both past and current depression were associated with an increase in the risk of novel fractures: sub-hazard ratio = 1.29 (95%CI = 1.03, 1.63) and 1.27 (95%CI = 1.05, 1.55) respectively. Estimation of confounding due to unmeasured factors showed that a small additional effect could potentially dilute the association between depression and fractures. DISCUSSION History of clinically significant symptoms of depression is associated with an increased risk of future fractures. This association may be due to multiple other associated risk factors, both measured and unmeasured, but nevertheless the presence of depression should alert clinicians to the need to develop a management plan that includes the management not only of depression but also of fracture risk.

Age-Related Male Hypogonadism and Cognitive Impairment in the Elderly: Focus on the Effects of Testosterone Replacement Therapy on Cognition. Geriatrics (Basel) 2020; 5:geriatrics5040076.

Abstract
BACKGROUND Epidemiological data report that male hypogonadism may play a role in cognitive impairment in elderly. However, the effect of testosterone replacement therapy (TRT) on cognitive abilities in this cluster of patients has not been well established. Methods. PubMed/MEDLINE, Google Scholar, Cochrane Library, and Web of Science were searched by using free text words and medical subject headings terms related with "male hypogonadism", "late-onset hypogonadism", elderly, cognition, "mild cognitive impairment", memory, "testosterone replacement therapy" used in various combinations according to the specific clinical questions. Original articles, reviews, and randomized controlled trials written in English were selected. Results. A long-term TRT could improve specific cognitive functions, such as verbal and spatial memory, cognitive flexibility, and physical vitality. However, randomized controlled trials do not provide positive results, and in most of the cases TRT might not induce beneficial effects on cognitive function in elderly men. Discussion and conclusions. Since the lengthening of life expectancy, the prevalence rate of cognitive decline in elderly men is expected to increase remarkably over the next decade with considerable healthcare and economical concerns. Therefore, this remains a relevant clinical topic and further investigations are needed for clarifying the role of TRT especially in elderly men with hypogonadism.

Abstract
BACKGROUND Long-term air pollution exposure has been associated with increased risk of mortality and stroke. Less is known about the risk at lower concentrations. The association of long-term exposure to PM2.5, PM2.5 absorbance, NO2, and NOx with all-cause mortality and stroke was investigated in a cohort of men aged ≥ 65 years who lived in metropolitan Perth, Western Australia. METHODS Land use regression models were used to estimate long-term exposure to air pollutants at participant's home address (n = 11,627) over 16 years. Different metrics of exposure were assigned: baseline; year before the outcome event; and average exposure across follow-up period. The Mortality Register and Hospital Morbidity Data from the Western Australia Data Linkage System were used to ascertain mortality and stroke cases. Hazard ratios (HRs) and 95% confidence intervals were estimated using Cox proportional hazard models, adjusting for age, smoking, education, and body mass index for all-cause mortality. For fatal and hospitalized stroke, the models included variables controlled for all-cause mortality plus hypertension. RESULTS Fifty-four percent of all-participants died, 3% suffered a fatal stroke, and 14% were hospitalized stroke cases. PM2.5 absorbance increased the risk of all-cause mortality with adjusted HR of 1.12 (1.02-1.23) for baseline and average exposures, and 1.14 (1.02-1.24) for past-year exposure. There were no associations between PM2.5 absorbance, NO2, and NOx and stroke outcomes. However, PM2.5 was associated with reduced risks of fatal stroke. CONCLUSION Long-term exposure to PM2.5 absorbance was associated with all-cause mortality among older men exposed to low concentrations; and exposure to PM2.5 was associated with reduced risk of fatal stroke.

Abstract
Background The Framingham Risk Score estimates the 10‐year risk of cardiovascular events. However, it performs poorly in older adults. We evaluated the incremental benefit of adding high‐sensitivity cardiac troponin I (hs‐cTnI) to the Framingham Risk Score. Methods and Results The HIMS (Health in Men Study) is a cohort study of community‐dwelling men aged 70 to 89 years in Western Australia. Participants were identified from the electoral roll, with a subset undergoing plasma analysis. Hs‐cTnI (Abbott Architect i2000SR) was measured in 1151 men without prior cardiovascular disease. The Western Australia Data Linkage System was used to identify incident cardiovascular events. After 10 years of follow‐up, 252 men (22%) had a cardiovascular event (CVE+) and 899 did not (CVE–). The Framingham Risk Score placed 148 (59%) CVE+ and 415 (46%) CVE– in the high‐risk category. In CVE– men, adding hs‐cTnI affected the risk categories of 244 (27.2%) men, with 64.8% appropriately reclassified to a lower and 35.2% to a higher category, which decreased the number of high‐risk men in the CVE– to 39%. In CVE+ men, adding hs‐cTnI affected the risk categories of 61 (24.2%), with 50.8% appropriately reclassified to a higher and 49.2% to a lower category and 82.5% remaining above the 15% risk treatment threshold. The net reclassification index was 0.305 (P<0.001). Adding hs‐cTnI increased the C‐statistic modestly from 0.588 (95% CI, 0.552–0.624) to 0.624 (95% CI, 0.589–0.659) and improved model fit (likelihood ratio test, P<0.001). Conclusions Adding hs‐cTnI to the Framingham Risk Score provided incremental prognostic benefit in older men, especially aiding reclassification of individuals into a lower risk category.

Abstract
While life expectancy continues to increase, aging can bring several distinct
endocrine and psychosocial changes. The study aimed to investigate the interplay
between biopsychosocial factors of healthy aging in specifically healthy aging
men. Ninety-seven healthy aging men were investigated at two time points
spanning 4 years. Participants completed questionnaires measuring several
psychosocial dimensions and gave saliva samples for hormone quantification
during a laboratory appointment. The study applied a random intercept
mixed-model approach. Age-related changes were found in most endocrine markers
(cortisol, testosterone, dehydroepiandrosterone-sulfate, and progesterone),
except for estradiol. Psychosocial measures remained stable, except for
increased social support. Further, changes in endocrine and psychosocial
measures were independent of each other. The results suggest that in healthy
aging men, age-related endocrine changes occur, but do not necessarily determine
a change in psychosocial measures. Potentially, preventive interventions can be
derived from these results.

Abstract
INTRODUCTION This study aims to clarify the role(s) of endogenous sex hormones to influence health outcomes in men, specifically to define the associations of plasma testosterone with incidence of cardiovascular events, cancer, dementia and mortality risk, and to identify factors predicting testosterone concentrations. Data will be accrued from at least three Australian, two European and four North American population-based cohorts involving approximately 20 000 men. METHODS AND ANALYSIS Eligible studies include prospective cohort studies with baseline testosterone concentrations measured using mass spectrometry and 5 years of follow-up data on incident cardiovascular events, mortality, cancer diagnoses or deaths, new-onset dementia or decline in cognitive function recorded. Data for men, who were not taking androgens or drugs suppressing testosterone production, metabolism or action; and had no prior orchidectomy, are eligible. Systematic literature searches were conducted from 14 June 2019 to 31 December 2019, with no date range set for searches. Aggregate level data will be sought where individual participant data (IPD) are not available. One-stage IPD random-effects meta-analyses will be performed, using linear mixed models, generalised linear mixed models and either stratified or frailty-augmented Cox regression models.

U-Shaped Association of Plasma Testosterone, and no Association of Plasma Estradiol, with Incidence of Fractures in Men. J Clin Endocrinol Metab 2020; 105:5802679. [PMID: 32155267 DOI: 10.1210/clinem/dgaa115] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/14/2019] [Accepted: 03/04/2020] [Indexed: 02/13/2023]
Abstract
PURPOSE Whether androgens, distinct from estrogen, maintain bone health during male aging has implications for understanding osteoporosis. We assessed associations of different sex hormones with incidence of any bone fracture or hip fracture in older men. PARTICIPANTS AND METHODS Analysis of 3307 community-dwelling men aged 76.8 ± 3.5 years, median follow-up period of 10.6 years. Plasma testosterone (T), dihydrotestosterone (DHT), and estradiol (E2) assayed by mass spectrometry, sex hormone-binding globulin (SHBG), and luteinizing hormone (LH) using immunoassay. Incident fractures determined via data linkage. We analyzed probability of fracture and performed Cox regression adjusted for age, medical comorbidities, and frailty. RESULTS Incident fractures occurred in 330 men, including 144 hip fractures. Probability plots suggested nonlinear relationships between hormones and risk of any fracture and hip fracture, with higher risk at lower and higher plasma T, lower E2, higher SHBG, and higher LH. In fully adjusted models, there was a U-shaped association of plasma T with incidence of any fracture (Quartile 2 [Q2] versus Q1: fully adjusted hazard ratio [HR] = 0.69, 95% confidence interval [CI] 0.51-0.94, P = .020; Q3: HR 0.59, 95% CI 0.42-0.83, P = .002) and hip fracture (Q2 versus Q1: HR 0.60, 95% CI 0.37-0.93, P = .043; Q3: HR 0.52, 95% CI 0.31-0.88, P = .015). DHT, E2, and LH were not associated with fracture. Higher SHBG was associated with hip fracture (Q4 versus Q1: HR 1.76, 95% CI 1.05-2.96, P = .033). CONCLUSIONS Midrange plasma T was associated with lower incidence of any fracture and hip fracture, and higher SHBG with increased risk of hip fracture. Circulating androgen rather than estrogen represents a biomarker for hormone effects on bone driving fracture risk.

Abstract
Objectives: To determine if the excess mortality associated with Bipolar disorder (BD) is independent of lifestyle.Methods: Prospective study of a community-representative sample of 12,203 men aged 65-85 years followed for 17.7 years. We used the 8-item 'prudence score' to assesses lifestyle behaviours, including the use of alcohol and smoking, physical activity, body mass and key aspects of diet. Scores of 5 or more indicate a prudent lifestyle.Results: 69 (0.6%) men had BD - a larger proportion of them than the remainder of the sample had diabetes, ischaemic heart disease, stroke, chronic respiratory diseases and dementia. The odds of a prudent lifestyle were 40% lower among participants with BD. BD was associated with increased risk of future contact with health services due to ischaemic heart disease and cancer, and respiratory, digestive and renal diseases, although such risk became comparable to that of men without BD for men with BD and a prudent lifestyle. The adjusted mortality hazard associated with the diagnosis of BD was 1.66 (95%CI = 1.20, 2.28), while the mortality hazard associated with a prudent lifestyle was 0.81 (95%CI = 0.78, 0.85). The mortality hazard for men with BD who were also prudent was 0.83 (95%CI = 0.52, 1.30). All analyses were adjusted for sociodemographic measures and prevalent morbidities.Conclusion: The excess morbidity and mortality of older men with BD seems to be mediated by non-prudent lifestyle practices. If future studies can demonstrate that this association is causal, then lifestyle interventions will need to become an integral part of the management of older adults with BD.

Abstract
CONTEXT Diabetes mellitus is conventionally associated with an increased risk of cancer; however, inverse associations of diabetes with prostate cancer are well described. Mechanisms are unclear, although hormonal factors, including alterations in sex hormone and IGF1 concentrations due to metabolic disturbances, have been hypothesized to play a role. OBJECTIVE To assess sex hormones, IGF1, glucose, and advanced glycation end products (AGEs) as potential mediators of the association between diabetes mellitus and prostate cancer. DESIGN AND PARTICIPANTS Longitudinal cohort study. The association of baseline diabetes with prostate cancer incidence was assessed using proportional hazards competing risks analysis in 3149 men followed for 12 years. Baseline hormone, glucose, and carboxymethyllysine (CML) levels were examined as potential mediators of this association. RESULTS Diabetes was associated with a lower prostate cancer risk (fully adjusted subhazard ratio, 0.63; 95% CI, 0.43 to 0.92; P = 0.017). This association was unchanged after accounting for testosterone, DHT, estradiol, or SHBG. Similarly, the addition of IGF1 or its binding proteins 1 and 3, or glucose, did not alter this association. CML was not associated with the risk of prostate cancer, and additional correction for CML in the fully adjusted model did not alter the inverse association of diabetes and prostate cancer risk. CONCLUSIONS In this study, alterations in sex hormone, IGF1, glucose, and CML levels did not account for the inverse association of diabetes and prostate cancer risk. Further studies are required to provide more insight into underlying causes of this association.

Abstract
AIMS We examined associations of ferritin and 25-hydroxyvitamin D with fasting glucose and prevalent diabetes in older men. METHODS Cross-sectional analysis of 4153 community-dwelling men aged 70 to 89 years in Western Australia. Plasma ferritin, 25-hydroxyvitamin D, and glucose were assayed. Diabetes was ascertained from self-report, medications, and fasting glucose. RESULTS There were 577 men with diabetes (13.9%). In the whole cohort, ferritin was associated with fasting glucose (0.051 mmol/L per 1 SD increase in ferritin, P = .006) and 25-hydroxyvitamin D was inversely associated (-0.085 mmol/L per 1 SD, P < .001). Ferritin was not associated with prevalent diabetes (highest vs. lowest quartile; >225 vs <66 μg/L: adjusted odds ratio [OR] 0.97, 95% confidence interval [CI], 0.74-1.27, P = .83). Higher vitamin D was associated with decreased odds of prevalent diabetes (highest vs lowest quartile; >82 nmol/L vs <53 nmol/L: OR = 0.57, 95% CI = 0.43-0.75, P < .001). There was no interaction between ferritin and vitamin D on diabetes risk. CONCLUSIONS In older men, ferritin is associated with fasting glucose but not prevalent diabetes. Higher 25-hydroxyvitamin D concentrations are independently associated with lower fasting glucose and reduced risk of diabetes. Clinical trials are required to determine whether interventions, which raise vitamin D concentrations, would reduce incidence of diabetes in this expanding demographic group.

Abstract
INTRODUCTION It is uncertain whether depression and exposure to antidepressants increase the risk of cardiovascular events in later life. This study attempts to clarify whether the risk of cardiovascular events associated with exposure to antidepressant medications varies according to history of depression. METHODS Cohort study of 5522 Australian men aged 70-89 years living in the metropolitan region of Perth, Western Australia, who were followed for novel cardiovascular events over 12 years. Clinical diagnoses followed the International Classification of Diseases (ICD) codes for ischaemic heart disease, cerebrovascular events and depressive disorders. Participants self-reported their use of medications. Other study measures included age, schooling, smoking history and the following concurrent morbidities: diabetes, hypertension, cancer, dementia, and respiratory diseases, gastrointestinal and renal diseases. RESULTS 374 men (6.8%) had a recorded or current diagnosis of depression and 365 (6.6%) were using an antidepressant. Prevalent depression and antidepressant use were associated with increased mortality hazard, but not the interaction between them (hazard ratio, HR = 0.46, 95%CI = 0.33, 0.65). Depression (HR = 1.50, 95%CI = 1.21, 1.86) and antidepressants (HR = 1.52, 95%CI = 1.20, 1.93) were associated with an increased risk of cardiovascular events, but the interaction term was associated with decreased risk (HR = 0.51, 95%CI = 0.30, 0.87). All analyses were adjusted for other study measures. DISCUSSION Depression and antidepressant use were associated with an increase in the 12-year risk of cardiovascular events, while antidepressants were associated with a decrease in the risk of cardiovascular events among older men with depression, but not among those without. This suggests that the effect of this interaction on the risk of cardiovascular events may be driven by the ability of antidepressants to lead to clinical improvements in mood.

Abstract
BACKGROUND/AIM Natural outdoor environments may mitigate harmful environmental factors associated with city living. We studied the longitudinal relationship between natural ('green and blue') outdoor environments and mortality in a cohort of older men residing in Perth, Western Australia. METHODS We studied a cohort of 9218 men aged 65 years and older from the Health In Men Study. Participants were recruited in 1996-99 and followed until 2014, during which 5889 deaths were observed. Time-varying residential surrounding greenness based on the Normalized Difference Vegetation Index, and the number and size of parks, natural space and waterbodies were defined to characterize the natural outdoor environment. All-cause non-accidental and cause-specific mortality was ascertained with the Western Australian Data Linkage System. The association of the natural outdoor environment with mortality was examined using Cox regression analysis. RESULTS After adjusting for age, men living in the highest quartile of cumulative average surrounding greenness had a 9% lower rate of all-cause non-accidental mortality (95% confidence interval [CI] 0.84, 0.98; p = .013) compared with those in the lowest quartile. This association was no longer present after adjustment for other risk factors, especially level of education. Living within 500 m of one (vs. no) natural space was associated with decreased mortality risk (adjusted hazard ratio 0.93; 95% CI 0.86, 1.00; p = .046), but no association with mortality was found for two or more natural spaces compared to none and for parks. Associations between waterbodies and mortality were inconsistent, showing non-linear beneficial and harmful associations. CONCLUSIONS In this longitudinal study of older men residing in Perth, we observed evidence suggestive of an association between access to natural spaces and decreased mortality. Associations between surrounding greenness and mortality seemed to be confounded by level of education, and associations with waterbodies were complex and need to be studied further.

Cross-sectional associations of sex hormones with leucocyte telomere length, a marker of biological age, in a community-based cohort of older men. Clin Endocrinol (Oxf) 2019; 90:562-569. [PMID: 30561819 DOI: 10.1111/cen.13918] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/06/2018] [Revised: 12/11/2018] [Accepted: 12/12/2018] [Indexed: 01/29/2023]
Abstract
CONTEXT Telomeres protect chromosomes from damage, and shorter leucocyte telomere length (LTL) is a marker of advancing biological age. The association between testosterone (T) and its bioactive metabolites, dihydrotestosterone (DHT) and oestradiol (E2) with telomere length, particularly in older men, is uncertain. The study aimed to clarify associations of sex hormones with LTL in older men. PARTICIPANTS AND METHODS We used cross-sectional data from 2913 men aged 76.7 ± 3.2 years with morning blood samples assayed for T, DHT, E2 (mass spectrometry), and sex hormone-binding globulin (SHBG, immunoassay), to correlate sex hormones with LTL measured using PCR and expressed as T/S ratio in multivariable linear regression models adjusted for age, cardiometabolic risk factors and cardiovascular disease history. RESULTS Average difference per decade of age was T -0.46 nmol/L, DHT -0.11 nmol/L, E2 -7.5 pmol/L, SHBG +10.2 nmol/L and LTL (T/S ratio) -0.065. E2 correlated with T/S ratio (r = 0.038, P = 0.039) and SHBG was inversely correlated (r = -0.053, P = 0.004). After multivariable adjustment, E2 was associated with T/S ratio (per 1 SD increase E2: coefficient 0.011, P = 0.043), T and DHT were not associated. When E2 and SHBG were simultaneously included, E2 remained positively (coefficient 0.014, P = 0.014) and SHBG inversely (coefficient -0.013, P = 0.037) associated with T/S ratio. CONCLUSIONS In older men, neither T nor DHT is associated with LTL while E2 is independently associated with LTL and SHBG is inversely associated, thus relating sex hormone exposure to lower biological age. Further research is needed to determine causality and clarify the role of sex hormones in male ageing.

Abstract
OBJECTIVE To determine if hearing loss is associated with increased risk of incident psychosis in later life. METHODS Longitudinal cohort study of a community-representative sample of 38 173 men aged 65 to 85 years at the start of the follow-up period of 18 years. We used the Western Australian Data Linkage System to ascertain the presence of hearing loss and of psychotic disorders according to the International Classification of Diseases (ICD) (versions 8, 9, and 10). We also collected information on concurrent morbidities: cancer and diseases of the cardiovascular, respiratory, digestive, and renal systems. RESULTS One thousand four hundred forty-two (3.8%) and 464 (1.2%) men had a recorded diagnosis of hearing loss and psychosis at the start of follow-up. After excluding the 464 participants with prevalent psychosis, 37 709 men were available for the longitudinal study, and of these, 252 (0.7%) developed a psychotic disorder. Competing risk regression showed that hearing loss was associated incident psychosis (subhazard ratio = 2.03, 95% CI, 1.24-3.32; after statistical adjustment for age and concurrent morbidities). CONCLUSIONS Hearing loss is associated with double the risk of incident psychosis in older men. Available evidence suggests that this link could be causal, although conclusive evidence is still missing from randomized controlled trials designed to test the effect of correction of hearing loss on the prevalence and incidence of psychosis.

Higher circulating androgens and higher physical activity levels are associated with less central adiposity and lower risk of cardiovascular death in older men. Clin Endocrinol (Oxf) 2019; 90:375-383.

Abstract
OBJECTIVE Low endogenous sex hormones and low physical activity (PA) levels have been associated with CVD risk. Whether these interact to influence CVD outcomes remains unclear. We assessed whether sex hormone concentrations and PA were additively associated with lower central adiposity and CVD risk. PATIENTS 3351 community-dwelling men, mean age 77 years. MEASUREMENTS Baseline testosterone (T), dihydrotestosterone (DHT) and oestradiol (E2) were assayed. Levels of PA were ascertained by questionnaire. Men were stratified using median splits into high hormone + high PA (H/H), high hormone + low PA (H/L); low hormone + high PA (L/H) and low hormone + low PA (L/L) groups. RESULTS A total of 865 CVD events and 499 CVD deaths occurred during 10-year mean follow-up. Men with higher T, DHT or SHBG and higher PA had the lowest BMI, waist circumference and risk of metabolic syndrome. Men with higher T had the lowest risk of incident CVD events, irrespective of PA level. Men with higher T or DHT and higher PA had the lowest risk of dying from CVD (eg, hazard ratios for T/PA H/H 0.76 P = 0.031; H/L 0.85 P = 0.222; L/H 0.80 P = 0.075; L/L 1.00). CONCLUSION Higher circulating androgens and higher PA were associated with less central adiposity at baseline and fewer CVD deaths during follow-up. These findings are consistent with a potential additive effect of androgens and PA on cardiometabolic outcomes in older men.

Abstract
BACKGROUND Low circulating testosterone has been associated with dementia in older men but existing evidence from prospective studies is inconsistent. METHODS We conducted a prospective longitudinal study of 4069 community-dwelling older men free of dementia aged 71-88 years at baseline. The main objective of the study was to determine if men with low circulating sex hormones were more likely to develop dementia over time. The main biochemical exposures of interest were collected at baseline between 2001 and 2004 and men were assessed for incident dementia via an electronic health records database to the 31 st of December 2013. RESULTS Dementia developed in 499 men over a median of 10.5 years (range 9.4-12.2 years). The risk of developing dementia increased with decreasing total (hazard ratio [HR] 1.14, 95% confidence interval [95%CI] 1.03-1.26 per standard deviation decrease) and calculated free testosterone (HR 1.18, 95%CI 1.06-1.31 per standard deviation decrease) after adjustment for age, baseline cognitive function, depression, body mass, hypertension, cardiovascular disease and total plasma homocysteine. Men in the lowest quartiles of total (adjusted HR 1.39, 95%CI 1.04-1.85) and calculated free testosterone (adjusted HR 1.43, 95%CI 1.08-1.90) had increased risk of developing dementia compared to those in the highest quartiles. CONCLUSIONS Lower plasma total and calculated free testosterone were associated with increased risk of developing dementia independent of relevant measured clinical and biochemical factors and was not explained due to differential mortality in those with lower testosterone levels. The association between low testosterone and dementia is biologically plausible but data on the role of testosterone treatment in preventing dementia is lacking and adequately powered trials in men at risk would be welcome.

Older men with bipolar disorder diagnosed in early and later life: Physical health morbidity and general hospital service use. J Affect Disord 2018; 241:269-274. [PMID: 30138812 DOI: 10.1016/j.jad.2018.08.035] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/13/2018] [Revised: 08/01/2018] [Accepted: 08/07/2018] [Indexed: 01/05/2023]
Abstract
BACKGROUND Bipolar disorder (BD) has been associated with greater health morbidity burden, but it is unclear if this association is affected by age at the time of diagnosis and how this might impact on the use of general hospital services. METHODS Cross-sectional study investigating the prevalence of common medical morbidities among participants with early (EOBD) and late onset diagnosis of BD (LOBD - age at diagnosis ≥ 60 years) derived from a community-representative sample of 37,183 men aged 65-85 years. Cohort study over a follow up period of up to 17.7 years investigating the hazard of general hospital use among older men associated with EOBD and LOBD taking into account age and prevalent medical morbidities. RESULTS 250 older men had a recorded diagnosis of BD, 75 of whom had LOBD. Diabetes, stroke and diseases of the respiratory and digestive systems were more frequent in men with than without BD. There were no differences in the distribution of medical morbidities between men with EOBD and LOBD. The adjusted hazard ratio (HR) of contact with general hospital services was significantly higher among men with EOBD (HR = 1.33; 95%CI = 1.14, 1.54) and LOBD (HR = 1.27, 95%CI = 1.06, 1.51) compared with older men without BD. Older men with EOBD had the highest number of contacts with general hospital services during follow up, although men with EOBD and LOBD did not differ in the number of contacts due to episodes of mania or depression. The medical reasons for contact with general hospital services of men with EOBD and LOBD overlapped but were not identical. CONCLUSIONS Older men with BD experience greater health morbidity than men without BD. Older men with BD access hospital services for the management of physical morbidities earlier and more frequently than men without BD. Age at the time of diagnosis of BD has limited impact on the risk of contact with general medical services, although subtle differences in the physical morbidity of men with EOBD and LOBD warrant further investigation.

Abstract
BACKGROUND Diabetes mellitus is associated with increased fracture risk despite preservation of bone density and reduced bone turnover. AIMS We tested the hypothesis that circulating advanced glycation end products (AGEs) and endogenous secretory receptor for AGEs (esRAGE) differentially modulate bone turnover and predict fracture risk in older men. PARTICIPANTS A total of 3384 community-dwelling men aged 70 to 89 years. METHODS Collagen type I C-terminal cross-linked telopeptide, N-terminal propeptide of type I collagen (P1NP), and total osteocalcin (TOC) were assayed using immunoassay and undercarboxylated osteocalcin (ucOC) following hydroxyapatite binding. Plasma N-carboxymethyllysine (CML) and esRAGE were assayed using immunoassay. Methylglyoxal and glyoxal were assayed using mass spectrometry. Incident hip fractures were ascertained. RESULTS Median age was 76.3 years (interquartile range, 74.2 to 79.1 years). Plasma CML was measured in 3011 men, methylglyoxal and glyoxal in 766 men, and esRAGE in 748 men. Plasma CML, methylglyoxal, glyoxal, and esRAGE were similar in men without and with diabetes (all P > 0.05). CML was positively associated with fasting glucose (r = 0.06, P < 0.001), and esRAGE was inversely associated (r = -0.08, P = 0.045). esRAGE was positively associated with bone formation (P1NP, r = 0.17, P < 0.001; ucOC, r = 0.11, P = 0.008; TOC, r = 0.16, P < 0.001). Incident hip fractures occurred in 106 men during follow-up. Men with CML in the third quartile of values had reduced incidence of hip fracture compared with men in the lowest quartile (hazard ratio, 0.49; 95% CI, 0.24 to 0.99; P = 0.045). CONCLUSIONS Glycemia associates positively with CML and reciprocally with esRAGE in older men. Circulating esRAGE modulates bone turnover in older men, whereas CML predicts incidence of hip fracture.

Risk of prevalent and incident dementia associated with insulin-like growth factor and insulin-like growth factor-binding protein 3. Mol Psychiatry 2018; 23:1825-1829. [PMID: 29155799 DOI: 10.1038/mp.2017.152] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/06/2017] [Revised: 04/20/2017] [Accepted: 05/10/2017] [Indexed: 12/28/2022]
Abstract
Insulin-like growth factor 1 (IGF-1) influences cell proliferation and survival. In the extracellular environment, IGF-1 circulates bound to proteins (IGF-binding proteins; IGFBP), some of which have physiological effects that seem independent of IGF-1, including the brain (for example, IGFBP-3). We completed a systematic review of the association between dementia and IGF-1 and IGFBP-3, and a cross-sectional and longitudinal study designed to investigate if lower plasma concentration of these proteins increased the risk of prevalent and incident dementia. A total of 3967 men aged 71-89 years joined the study, of whom 535 (13.5%) showed evidence of prevalent cognitive impairment. The plasma concentrations of IGF-1 and IGFBP-3 were similar for men with and without cognitive impairment. The 3432 men free of cognitive impairment were then followed for up to 13 years. During this time 571 (16.6%) developed dementia. The plasma concentration of IGF-1 had no association with incident dementia. The doubling of the plasma concentration of IGFBP-3 decreased the hazard ratio of dementia by 23% (95% confidence interval=5-37%). The results were not affected by age, body mass index and history of smoking, diabetes, hypertension, coronary heart disease or stroke. If these findings are confirmed by others, the plasma concentration of IGFBP-3 could be used to improve the accuracy of predictive models of dementia and as a potential new factor to assist in the development of prevention and treatment strategies.

Abstract
OBJECTIVE Overt thyroid dysfunction is a risk factor for osteoporosis and fractures. Subclinical hyperthyroidism has also been associated with fracture. It remains unclear whether variation in thyroid hormones within the euthyroid range modulates bone health, particularly among older men. We assessed whether thyroid stimulating hormone (TSH) and free thyroxine (FT4) are associated with bone turnover markers (BTMs) and predict hip fracture risk in community-dwelling older men without known thyroid disease. DESIGN Prospective cohort study. PATIENTS Four thousand two hundred forty-eight men aged 70-89 years. MEASUREMENTS Baseline blood samples were assayed for TSH, FT4, total osteocalcin (TOC), undercarboxylated osteocalcin (ucOC), N-terminal propeptide of type I collagen (P1NP) and collagen type I C-terminal cross-linked telopeptide (CTX). Incidence of hip fracture events was ascertained to 2012. Associations of TSH and FT4 with BTMs were analysed at baseline using Pearson correlation coefficients, and with incident hip fracture using Cox proportional hazards regression. RESULTS After excluding men with pre-existing thyroid or bone disease, there were 3, 338 men for analysis. Of these, 3, 117 were euthyroid, 135 had subclinical hypothyroidism, and 86 had subclinical hyperthyroidism. Men with subclinical thyroid disease were older, and those with subclinical hyperthyroidism had lower creatinine than the other groups. After multivariate analysis, there were no associations found between FT4, TSH or subclinical thyroid dysfunction and BTMs at baseline. Neither subclinical thyroid dysfunction, TSH nor FT4 were predictive of incident hip fracture in our study population. CONCLUSIONS In euthyroid older men, TSH and FT4 were not associated with BTMs or incident hip fracture. Our findings differ from those previously described in postmenopausal women.

Abstract
Background Previous findings suggest that apathy symptoms independently of depressive symptoms measured using the Geriatric Depression Scale (GDS) are associated with cardiovascular disease (CVD) in older individuals. Aims To study whether apathy and depressive symptoms in older people are associated with future CVD, stroke, and mortality using individual patient-data meta-analysis. Methods Medline, Embase, and PsycInfo databases up to September 3, 2013, were systematically searched without language restrictions. We sought prospective studies with older (mean age ≥65 years) community-dwelling populations in which the GDS was employed and subsequent stroke and/or CVD were recorded to provide individual participant data. Apathy symptoms were defined as the three apathy-related subitems of the GDS, with depressive symptoms the remaining items. We used myocardial infarction (MI), stroke, and all-cause mortality as main outcomes. Analyses were adjusted for age, sex, and MI/stroke history. An adaptation of the Newcastle–Ottawa scale was used to evaluate bias. Hazard ratios were calculated using one-stage random-effect Cox regression models. Results Of the 52 eligible studies, 21 (40.4%) were included, comprising 47,625 older people (mean age [standard deviation] 74 [7.4] years), over a median follow-up of 8.8 years. Participants with apathy symptoms had a 21% higher risk of MI (95% confidence interval [CI] 1.08–1.36), a 37% higher risk of stroke (95% CI 1.18–1.59), and a 47% higher risk of all-cause mortality (95% CI 1.38–1.56). Participants with depressive symptoms had a comparably higher risk of stroke (HR 1.36, 95% CI 1.18–1.56) and all-cause mortality (HR 1.44, 95% CI 1.35–1.53), but not of MI (HR 1.08, 95% CI 0.91–1.29). Associations for isolated apathy and isolated depressive symptoms were comparable. Sensitivity analyses according to risk of bias yielded similar results. Conclusion Our findings stress the clinical importance of recognizing apathy independently of depressive symptoms, and could help physicians identify persons at increased risk of vascular disease.

Morar B, Badcock JC, Phillips M, Almeida OP, Jablensky A. The longevity gene Klotho is differentially associated with cognition in subtypes of schizophrenia. Schizophr Res 2018; 193:348-353. [PMID: 28673754 DOI: 10.1016/j.schres.2017.06.054] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/14/2016] [Revised: 06/22/2017] [Accepted: 06/27/2017] [Indexed: 01/10/2023]
Abstract
Cognitive impairment is a core feature of schizophrenia and impacts negatively the functioning of affected individuals. Cognitive decline correlates with aging, and is the primary cause of loss of independence and reduced quality of life. The klotho gene is a key modulator of aging, with expression deficiency resulting in premature aging, while overexpression extends lifespan and enhances cognition. A haplotype and functional human variant of the gene, KL-VS, increases expression and promotes longevity. KL-VS heterozygosity is associated with enhanced cognition and a larger volume of the right dorsolateral prefrontal cortex, a region involved in planning and decision-making, which is especially susceptible to shrinkage with age. We examined the effect of KL-VS heterozygosity on cognition in 497 schizophrenia patients and 316 healthy controls from the Western Australian Family Study of Schizophrenia (WAFSS) who had been comprehensively characterised by neurocognitive tests and classified into cognitively deficient (CD) and cognitively "spared" (CS) clusters. An older, cognitively normal population sample from the Health in Men Study (HIMS) was included to allow assessment of heterozygosity and memory in aged individuals. We show that heterozygosity is associated with better learning and memory in the younger WAFSS healthy controls but not in the aging HIMS sample. However, in schizophrenia patients, KL-VS has a selective effect on memory, with heterozygotes in CD and CS clusters performing worse than non-carriers. This effect was significant and more severe in the CD cluster, reinforcing the utility of subtyping patients into CD and CS clusters that may differ in their genetic underpinnings.
