Abstract Objectives To investigate the association of loneliness and its component subscales with the risk of dementia in a general Japanese older population. Method A total of 1,141 community-dwelling Japanese residents aged ≥65 years without dementia were prospectively followed up for a median 5.0 years. We evaluated any loneliness and its component subscales—namely, social and emotional loneliness—by using the 6-item de Jong Gierveld Loneliness Scale. Cox proportional hazards models were used to estimate hazard ratios (HRs) of each loneliness type on the risk of dementia controlling for demographic factors, lifestyle factors, physical factors, social isolation factors, and depression. Results During the follow-up, 114 participants developed dementia. The age- and sex-adjusted incidence rate of dementia was significantly greater in participants with any loneliness and emotional loneliness than those without. The multivariable-adjusted HRs (95% confidence intervals) of participants with any loneliness and emotional loneliness on incident dementia were 1.61 (1.08–2.40) and 1.65 (1.07–2.54), respectively, as compared to those without. However, there was no significant association between social loneliness and dementia risk. In subgroup analyses of social isolation factors, excess risks of dementia associated with emotional loneliness were observed in participants who had a partner, lived with someone, or rarely communicated with relatives or friends, but such association was not significant in participants who had no partner, lived alone, or frequently communicated with friends or relatives. Discussion The present study suggested that loneliness, especially emotional loneliness, was a significant risk factor for the development of dementia in the general older population in Japan.

Abstract Aims To investigate the association between parity and the risk of incident dementia in women. Methods We pooled baseline and follow-up data for community-dwelling women aged 60 or older from six population-based, prospective cohort studies from four European and two Asian countries. We investigated the association between parity and incident dementia using Cox proportional hazards regression models adjusted for age, educational level, hypertension, diabetes mellitus and cohort, with additional analysis by dementia subtype (Alzheimer dementia (AD) and non-Alzheimer dementia (NAD)). Results Of 9756 women dementia-free at baseline, 7010 completed one or more follow-up assessments. The mean follow-up duration was 5.4 ± 3.1 years and dementia developed in 550 participants. The number of parities was associated with the risk of incident dementia (hazard ratio (HR) = 1.07, 95% confidence interval (CI) = 1.02–1.13). Grand multiparity (five or more parities) increased the risk of dementia by 30% compared to 1–4 parities (HR = 1.30, 95% CI = 1.02–1.67). The risk of NAD increased by 12% for every parity (HR = 1.12, 95% CI = 1.02–1.23) and by 60% for grand multiparity (HR = 1.60, 95% CI = 1.00–2.55), but the risk of AD was not significantly associated with parity. Conclusions Grand multiparity is a significant risk factor for dementia in women. This may have particularly important implications for women in low and middle-income countries where the fertility rate and prevalence of grand multiparity are high.

Chd Risk Factors

Objective: The independent prognostic value of prehypertension (preHTN) for incident coronary heart disease (CHD) remains unsettled. Using the REasons for Geographic And Racial Differences in Stroke (REGARDS) cohort study, we examined associations between preHTN and incident acute CHD and CVD death. Methods: REGARDS includes 30,239 black and white community-dwelling adults age 45 and older at baseline. Recruitment occurred from 2003-7, with baseline interviews and in-home data collection for physiologic measures. Follow-up is conducted by telephone every 6 months to detect events and deaths, which are adjudicated by experts. Systolic BP was categorized into <120 mmHg (n=4385), 120-129 mmHg (n=4000), 130-139 (n=2066), and hypertension was categorized into controlled (<140/90 mmHg on treatment) (n=8378), and uncontrolled (>140/90 mmHg) (n=5364). Incident acute CHD was defined as definite or probable myocardial infarction (MI) or acute CHD death. CVD death was defined as acute CHD, stroke, heart failure or other cardiovascular disease related. Cox proportional hazards models estimated the hazard ratios (HR) for incident CHD by BP categories, adjusting for sociodemographics and CHD risk factors. Results: The 23,393 participants free of CHD at baseline were followed for a median of 4.4 years. Mean age was 64.1, 58% were women and 42% were black. There was a significant interaction between sex and BP categories, therefore analyses were stratified by sex. There were 252 non-fatal and fatal acute CHD events among women and 407 among men. Among women, compared with SBP<120 mmHg, BP categories above SBP 120 mmHg were associated with incident CHD (adjusted HR for SBP120-129 mmHg=1.94 {95% CI 1.04-3.62]; SBP 130-139 mmHg=1.92 {0.95-3.87}; controlled HTN=2.16 {1.25-3.75}; uncontrolled HTN=3.25 {1.87-5.65}) in fully adjusted models. Among men, only uncontrolled HTN was associated with incident CHD (HR=1.55 {1.11-2.17}). Conclusion: In this sample, preHTN may be associated with incident CHD among women but not men.

Warfarin Treatment

SummaryThe ARISTOTLE trial showed a risk reduction of stroke/systemic embolism (SE) and major bleeding in non-valvular atrial fibrillation (NVAF) patients treated with apixaban compared to warfarin. This retrospective study used four large US claims databases (MarketScan, PharMetrics, Optum, and Humana) of NVAF patients newly initiating apixaban or warfarin from January 1, 2013 to September 30, 2015. After 1:1 warfarin-apixaban propensity score matching (PSM) within each database, the resulting patient records were pooled. Kaplan-Meier curves and Cox proportional hazards models were used to estimate the cumulative incidence and hazard ratios (HRs) of stroke/SE and major bleeding (identified using the first listed diagnosis of inpatient claims) within one year of therapy initiation. The study included a total of 76,940 (38,470 warfarin and 38,470 apixaban) patients. Among the 38,470 matched pairs, 14,563 were from MarketScan, 7,683 were from PharMetrics, 7,894 were from Optum, and 8,330 were from Humana. Baseline characteristics were balanced between the two cohorts with a mean (standard deviation [SD]) age of 71 (12) years and a mean (SD) CHA2DS2-VASc score of 3.2 (1.7). Apixaban initiators had a significantly lower risk of stroke/SE (HR: 0.67, 95 % CI: 0.59–0.76) and major bleeding (HR: 0.60, 95 % CI: 0.54–0.65) than warfarin initiators. Different types of stroke/SE and major bleeding – including ischaemic stroke, haemorrhagic stroke, SE, intracranial haemorrhage, gastrointestinal bleeding, and other major bleeding – were all significantly lower for apixaban compared to warfarin treatment. Subgroup analyses (apixaban dosage, age strata, CHA2DS2-VASc or HAS-BLED score strata, or dataset source) all show consistently lower risks of stroke/SE and major bleeding associated with apixaban as compared to warfarin treatment. This is the largest “real-world” study on apixaban effectiveness and safety to date, showing that apixaban initiation was associated with significant risk reductions in stroke/SE and major bleeding compared to warfarin initiation after PSM. These benefits were consistent across various high-risk subgroups and both the standard-and low-dose apixaban dose regimens.Note: The review process for this manuscript was fully handled by Christian Weber, Editor in Chief.Supplementary Material to this article is available online at www.thrombosis-online.com.

BackgroundDepression may increase the risk of mortality among certain subgroups of older people, but the part played by antidepressants in this association has not been thoroughly explored.AimsTo identify the characteristics of older populations who are most at risk of dying, as a function of depressive symptoms, gender and antidepressant use.MethodAdjusted Cox proportional hazards models were used to determine the association between depression and/or antidepressant use and 4-year survival of 7363 community-dwelling elderly people. Major depressive disorder was evaluated using a standardised psychiatric examination based on DSM-IV criteria and depressive symptoms were assessed using the Center for Epidemiological Studies Depression scale.ResultsDepressed men using antidepressants had the greatest risk of dying, with increasing depression severity corresponding to a higher hazard risk. Among women, only severe depression in the absence of treatment was significantly associated with mortality.ConclusionsThe association between depression and mortality is gender-dependent and varies according to symptom load and antidepressant use.

Objectives: To report the safety and efficacy results of a 9- to 15-year follow-up investigation among patients who had received Carpentier-Edwards Perimount (CE-P) bovine pericardial bioprostheses (Edwards Lifesciences, Irvine, CA, USA) for valve replacement. Methods: This retrospective study investigated freedom from structural valve deterioration (SVD) as well as survival and reoperation among different age and etiology groups in patients who were implanted with a CE-P bioprosthesis at Guangdong General Hospital between 2001 and 2007. Kaplan-Meier survival analysis and multivariate Cox proportional hazards regression were performed. Results: The mean age of the patients (N = 225) was only 61.2 ± 11.5 years at valve replacement. More than half of the patients (55.1%) had rheumatic heart disease. The survival rates were 86.46, 81.58, and 74.42% at 5 years, 64.39, 66.19, and 55.85% at 10 years, and 48.37, 57.33, and 46.54% at 15 years for the groups with mitral valve replacement (MVR), aortic valve replacement (AVR), and double valve replacement (DVR), respectively. The median time to freedom from SVD was 12.5, 13.2, and 11.2 years, respectively, for patients with MVR, AVR, and DVR. A higher age at valve replacement was a significant risk factor for SVD in all patients (p < 0.01). Conclusions: Good long-term clinical results of CE-P valves have been demonstrated in Chinese patients >60 years.

We use data from a population-based cohort of elderly Brazilians to assess predictors of hospitalizations during ten years of follow-up. Participants were 1,448 persons aged 60 years and over at baseline (1997). The outcome was self-reported number of hospitalizations per year. Slightly more than a fifth (23%) experienced no hospitalizations during the 10 year follow-up. About 30% had 1-2 events, 31% had between 3 and 7 events, and about 18% had 8 or more events during this time. Results of multivariable hurdle and Cox proportional hazards models showed that the risk of hospitalization was positively associated with male sex, increased age, chronic conditions, and visits to the doctors in the previous 12 months. Underweight was a predictor of any hospitalization, while obesity was an inconsistent predictor of hospitalization.

Increased Risk

Obesity and atrial fibrillation (AF) are increasing public health problems, especially among women. Overweight and obesity (as defined by WHO criteria) have been previously associated with incident AF in existing cohorts; however, relatively few women with AF were included. We sought to further characterize the risk of incident AF over the entire range of body mass index (BMI) in a large prospective cohort of women enrolled in the Women’s Health Study. Women included in this analysis provided information on BMI and were free of cardiovascular disease and AF at baseline. Among the 38,807 women, 1022 incident AF cases were reported (9.8 +/− 1.2 person-years of AF). Compared with women not reporting AF, those who developed AF were older (58.8 +/− 8.0 vs 54.4 +/− 6.9 years), had higher BMI (27.2 +/− 5.7 vs 26.0 +/−5.0 kg/m2), and were more often diabetic (4.3% vs 2.5%), hypertensive (41.5% vs 2.5%), and hyperlipidemic (35.4% vs 29.1%), p < 0.0001 for each comparison. Continuous BMI was associated with AF in age-adjusted (HR 1.05; 95%CI, 1.04 –1.06) and multivariable Cox proportional hazards models controlling for age, diabetes, hypertension, hyperlipidemia, smoking, and physical activity (HR = 1.04; 95%CI, 1.03–1.05, p < 0.0001). When BMI was divided into 7 pre-specified categories, risk of AF was significantly increased among those with a BMI > 30 (see graph). Compared with women with BMI < 21, women with BMI > 35 were at 1.90-fold (95%CI, 1.42–2.55) increased risk of AF even after controlling for the listed obesity-associated comorbidities. Conclusion: These prospective data suggest a nonlinear relationship between BMI and risk of AF, with significant risk above a BMI threshold of 30 kg/m2.

Objective:Prior studies indicate that olfactory function may be an early marker for cognitive impairment, but the body of evidence has been largely restricted to white populations.Methods:We studied 2,428 community-dwelling black and white older adults (baseline age 70–79 years) without dementia enrolled in the Health, Aging, and Body Composition (Health ABC) study. Olfaction was measured as odor identification (OI) with the 12-item Cross Cultural Smell Identification Test in year 3. We defined incident dementia over 12 years on the basis of hospitalization records, prescription for dementia medication, or 1.5-SD decline in race-stratified global cognition score. We assessed dementia risk associated with OI score (by tertile) using Cox proportional hazards models. All analyses were stratified by race.Results:Poorer OI in older adults without dementia was associated with increased risk of dementia. After adjustment for demographics, medical comorbidities, and lifestyle characteristics, white participants in the poor or moderate OI tertile had greater risk of dementia (adjusted hazard ratio [HR] 3.34, 95% confidence interval [CI] 2.45–4.54; and HR 1.84, 95% CI 1.33–2.54, respectively) compared to those in the good tertile of function. Among blacks, worse OI was associated with an increased risk of dementia, but the magnitude of the effect was weaker (p for interaction = 0.04) for the poor OI tertile (adjusted HR 2.03, 95% CI 1.44–2.84) and for the moderate tertile (adjusted HR 1.42, 95% CI 0.97–2.10). There was no interaction between OI and APOE ε4 and risk of dementia.Conclusions:While the magnitude of the association was stronger in whites, we found that poor OI was associated with increased risk of dementia among both black and white older adults.

ABSTRACTBackground:There is little information on the association of the APOEe4 allele and AD risk in African populations. In previous analyses from the Indianapolis-Ibadan dementia project, we have reported that APOE ε4 increased the risk for Alzheimer's disease (AD) in African Americans but not in Yoruba. This study represents a replication of this earlier work using enriched cohorts and extending the analysis to include cognitive decline.Methods:In this longitudinal study of two community dwelling cohorts of elderly Yoruba and African Americans, APOE genotyping was conducted from blood samples taken on or before 2001 (1,871 African Americans & 2,200 Yoruba). Mean follow up time was 8.5 years for African Americans and 8.8 years for Yoruba. The effects of heterozygosity or homozygosity of ε4 and of the possession of e4 on time to incident AD and on cognitive decline were determined using Cox's proportional hazards regression and mixed effects models.Results:After adjusting for covariates, one or two copies of the APOE ε4 allele were significant risk factors for incident AD (p < 0.0001) and cognitive decline in the African-American population (p < 0001). In the Yoruba, only homozygosity for APOE ε4 was a significant risk factor for AD (p = 0.0002) but not for cognitive decline (p = 0.2346), however, possession of an e4 allele was significant for both incident AD (p = 0.0489) and cognitive decline (p = 0.0425).Conclusions:In this large longitudinal comparative study, APOE ε4 had a significant, but weaker, effect on incident AD and on cognitive decline in Yoruba than in African Americans. The reasons for these differences remain unclear.

Background: Reduced physical function, an exemplary phenotype of aging, has been associated with cardiovascular disease (CVD). However, few studies have comprehensively investigated the association of physical function with risk of incident and recurrent CVD in community-dwelling older adults. Methods: Physical function, evaluated with the Short Performance Physical Battery (SPPB), was assessed in the ARIC study at visit 5 (2011-2013) among 5548 participants (mean age 75±5 years, female 58%, black 22%). The SPPB score was categorized into low (0-6), intermediate (7-9), and high (10-12) physical function. We assessed the associations of SPPB categories with composite and individual outcomes of coronary heart disease (CHD), stroke, or heart failure (HF) using Cox proportional hazards models adjusting for potential confounders. We also evaluated improvement in c-statistics by adding SPPB to covariates. Results: During a median follow-up of 6.2 years, there were 821 composite events (329 CHD, 226 stroke, and 467 HF cases). Compared to high SPPB score, low and intermediate SPPB score were robustly associated with higher risk of the composite CVD outcome (hazard ratio [HR] 1.59 [95% CI 1.29-1.95] and 1.32 [1.12-1.56], respectively) (Table). These associations were largely consistent between participants with and without a history of CVD at baseline. Among individual outcomes, low SPPB score showed the highest HR for stroke, whereas intermediate SPPB score was only significantly associated with HF. The addition of SPPB significantly improved c-statistic for composite outcome (Δc-statistic 0.006 [95% CI 0.002-0.009]), and the improvement was especially evident in participants without history of CVD (Δc-statistic 0.013 [0.003-0.023]). Conclusions: Lower physical function was robustly associated with the risk of CVD and improved its prediction beyond established predictors in older adults. Clinicians should pay attention to physical function when managing CVD risk in older adults.
