Objective Cardiovascular disease manifestation and several associated surrogate markers, such as vitamin D, have shown substantial seasonal variation. A promising cardiovascular biomarker, soluble ST2 (sST2), has not been investigated in this regard – we therefore determined if systemic levels of sST2 are affected by seasonality and/or vitamin D in order to investigate their clinical interrelation and usability. Design sST2 levels were measured in two cohorts involving hypertensive patients at cardiovascular risk, the Styrian Vitamin D Hypertension Trial (study A; RCT design, 8 weeks 2800 IU cholecalciferol daily) and the Ludwigshafen Risk and Cardiovascular Health Study (LURIC; study B; cross-sectional design). Methods The effects of a vitamin D intervention on sST2 levels were determined in study A using ANCOVA, while seasonality of sST2 levels was determined in study B using ANOVA. Results The concentrations of sST2 remained unchanged by a vitamin D intervention in study A, with a mean treatment effect (95% confidence interval) of 0.1 (−0.6 to 0.8) ng/mL; P = 0.761), despite a rise in 25(OH)D (11.3 (9.2–13.5) ng/mL; P < 0.001) compared to placebo. In study B, seasonal variations were present in 25(OH)D levels in men and women with or without heart failure (P < 0.001 for all subgroups), while sST2 levels remained unaffected by the seasons in all subgroups. Conclusions Our study provides the first evidence that systemic sST2 levels are not interrelated with vitamin D levels or influenced by the seasons in subjects at cardiovascular risk.

Abstract Background Inflammation is a major risk factor for frailty, but n-3 polyunsaturated fatty acids (PUFA) has been suggested as an anti-inflammatory agent. The present study aimed to investigate the hypothesis that the higher erythrocyte levels of long-chain n-3 PUFA were associated with lower odds of frailty and frailty criterion. Methods Cross-sectional analysis from the Korean Frailty and Aging Cohort Study, a total of 1,435 people aged 70–84 years were included. Sex- and age-stratified community residents, drawn in urban and rural regions nationwide, were eligible for participation in the study. All participants were categorized as frail and nonfrail according to the Cardiovascular Health Study index. Results The likelihood of frailty was inversely associated with the erythrocyte levels of eicosapentaenoic acid (EPA; odds ratio [OR] per unit 0.33; 95% confidence interval [CI] 0.14–0.77; p for trend = .002) and docosahexaenoic acid (DHA; OR per unit 0.42; 95% CI 0.20–0.87; p for trend = .018). Among each frailty criterion, the likelihood of slow walking speed was associated with erythrocyte levels of EPA and DHA, and the likelihood of exhaustion was inversely associated with the erythrocyte levels of DHA. Conclusions The present study showed that the frailty and frailty criterion were significantly associated with lower erythrocyte levels of long-chain n-3 PUFA, suggesting that lower n-3 PUFA could be a marker for the risk of frailty.

Abstract Myocardial strain, measured by speckle tracking echocardiography (STE), is a novel measure of subclinical cardiovascular disease and may reflect myocardial aging. We aimed to explore the association between myocardial strain and frailty, a clinical syndrome of impaired resilience and lack of physiologic reserve. Frailty was defined in 4,042 participants of the Cardiovascular Health Study (CHS) as having 3 or more of the following clinical criteria: weakness, slowness, shrinking, exhaustion, and inactivity. We examined the cross-sectional and longitudinal associations of left ventricular (LV) longitudinal strain, LV early diastolic strain rate and left atrial reservoir strain with frailty in participants with no history of cardiovascular disease or heart failure at the time of echocardiography. In cross-sectional analyses, LV longitudinal strain, LV early diastolic strain, left atrial reservoir strain and LV ejection fraction (measured by conventional echocardiography) levels were lower (worse) among frail participants than among those who were not frail and pre-frail (p&lt;0.01). This association of LV longitudinal strain and frailty was robust to adjustment by LV ejection fraction (adjusted OR: 1.34, 95% CI: 1.20, 2.09). Conversely, LV ejection fraction was not associated with frailty after adjustment for LV longitudinal strain. In longitudinal analyses, LV longitudinal strain and LV early diastolic strain were associated with incident frailty (adjusted OR: 1.49, 95% CI: 1.07, 2.08) and 1.65, 95% CI: 1.15, 2.25, respectively). In community-dwelling older adults without prevalent cardiovascular disease, worse LV longitudinal strain, reflective of subclinical myocardial dysfunction, was associated with frailty independent of LV ejection fraction and other risk factors.

Abstract In addition to intensity and quality, diversity of activity will be an important factor to explain health outcomes among older adults. Few studies, though, examined an association between activity diversity and health outcomes. This study aimed to examine the association between activity diversity and frailty among community-dwelling older Japanese. Participants were community-dwelling older adults who participated in a cohort study, the “Otassya-Kenshin” in 2018 . The participants were asked frequency of 20 daily activities, inside/outside chores, leisure activities with/without physically, direct/indirect contact with friends and so on, in a week and activity diversity score were calculated using the formula of Shannon’s entropy. Frailty was defined by the Japanese version of the Cardiovascular Health Study criteria. The difference in diversity score between frail and non frail were examined by t-test. Logistic regression analysis with covariates, age, sex, economic status, living alone, BMI, Mini-Mental State Examination, and IADL was adopted to find association between activity diversity score and presence of frailty. Of 652 participants (age: 72.8±6.3, women: 60.6%) analyzed, 27 (4.1%) were defined as frail. Frailty group revealed significantly lower activity diversity score than non-frailty group (0.66±0.11 vs 0.75±0.08, P&lt;0.01). 0.2 point of decrease in diversity score increase 5 times chance of frailty after controlling covariates. We found significant relationship between activity diversity and health outcome among older subjects. The activity diversity may provide additional information to number or intensity of activity.

Abstract The association of COMT with gait speed varies across studies; frailty, a condition increasing vulnerability to stressors, may influence this association. Cross-sectional data was obtained in 3,744 participants (71 years, 82% white, 39% male) for gait speed, frailty (Fried definition), and COMT. Multivariable regression models of COMT predicting gait were adjusted for demographics, chronic conditions, and locomotor factors. Interactions of COMT by frailty and by race predicting gait speed were p=0.03 and p=0.02, respectively. Compared to Met/Met, the Val/Val group walked marginally more slowly in the full cohort (0.87 vs 0.89 m/sec, p=0.2); differences were significant for those with frailty (n=220, 0.55 vs 0.63m/sec, p=0.03), but not for those with moderate (n=1691, 0.81 vs 0.81m/sec, p=0.9), or no frailty (n=1833, 0.98 vs 0.97 m/sec, p=0.7). Associations were similar by race, but significant for whites only. Studies should assess the influence of dopaminergic signaling on gait slowing due to frailty.
