The natural polyamine spermidine, known to be important for cellular function, decreases during aging. Previous research has demonstrated beneficial impact of spermidine intake on memory functions in both animal models and humans, suggesting that spermidine may be a preventive approach to delay age-related cognitive decline and possibly even Alzheimer’s disease (AD). However, the association of spermidine intake with brain health in humans is still unknown. In this study, we aimed to determine the association between dietary spermidine intake and structural brain measures in older individuals with subjective cognitive decline (SCD) and healthy controls (HC). Dietary spermidine intake and adherence to Mediterranean Diet (MeDi) were assessed by a self-reported food frequency questionnaire in 90 older adults with SCD and 47 HC. Processing of structural MRI data yielded global brain volumes, hippocampal volume, mean and regional cortical thickness, and cortical thickness in a template encompassing AD-vulnerable regions. In exploratory analyses, the association between spermidine intake and structural brain measures was assessed using adjusted and unadjusted linear regression models. Additionally, we tested for differential associations as a function of group. Mediation analyses were performed to examine whether dietary spermidine intake mediates the associations between adherence to MeDi and structural brain measures. Higher spermidine intake was associated with larger hippocampal volume (standardized β ​= ​0.262, p ​= ​0.002), greater mean cortical thickness (standardized β ​= ​0.187, p ​= ​0.031), and greater cortical thickness in AD-vulnerable brain regions (standardized β ​= ​0.176, p ​= ​0.042), the parietal (standardized β ​= ​0.202, p ​= ​0.020), and temporal lobes (standardized β ​= ​0.217, p ​= ​0.012). No significant differential effect emerged between older adults with SCD and HC. Moreover, a substantial mediating effect of dietary spermidine intake on the associations between adherence to MeDi and structural brain measures was observed. Higher dietary spermidine intake was positively associated with several structural brain measures, irrespective of the presence of SCD, and substantially mediated the relationship of adherence to MeDi and structural brain measures. Our data suggest that higher spermidine intake might be a promising dietary approach to preserve brain health in older adults, a hypothesis currently tested in an interventional trial. •First study on dietary spermidine intake and brain structure in older adults.•Spermidine intake is related to greater cortical thickness in AD-vulnerable regions.•Spermidine intake is associated with larger hippocampal volume.•Spermidine may be one decisive ingredient of Mediterranean Diet regarding brain health.

Dysphagia is associated with poor outcome, higher mortality, reduced quality of life, and social isolation. We investigate the relationship between swallowing impairment and symptoms of anxiety and depression after ischemic stroke. Consecutive patients with ischemic stroke participating in the prospective STROKE-CARD Registry study from 2020 to 2022 were assessed for dysphagia on hospital admission (clinical swallowing assessment) and for persistence until discharge and 3-month follow-up (SINGER Independency Index). Anxiety and depression symptoms were recorded using Beck Depression Inventory (BDI) and Hospital Anxiety and Depression Scale (HADS) at 3-month follow-up. Of 648 patients, 19.3% had dysphagia on admission, persisting in 14.8% at discharge and 6.8% at 3-month follow-up. With the presence or duration of dysphagia (no dysphagia, dysphagia at baseline, at discharge, at 3 months), score (mean ± SD) increased on the BDI (7.9 ± 6.7, 12.5 ± 8.7, 13.5 ± 9.0, 16.5 ± 10.2), HADS-D (4.4 ± 3.7, 7.1 ± 4.2, 7.7 ± 4.4, 9.8 ± 4.3), and HADS-A (4.4 ± 3.5, 5.4 ± 3.6, 6.0 ± 3.6, 7.0 ± 3.6). In linear regression analysis adjusting for age, sex, diabetes, dementia, and either functional disability or stroke severity, BDI and HADS-D scores were significantly higher in patients with dysphagia across all points in time (admission, discharge, 3-month follow-up). An independent association with HADS-A scores was only evident in patients with persisting dysphagia after 3 months. Patients with dysphagia were more likely to receive antidepressants, antipsychotics, or benzodiazepines at discharge and 3-month follow-up. Dysphagia after stroke is common and severely affects psychosocial functioning of individuals. Our results highlight swallowing impairment as an independent predictor for poststroke depressive and, to a lesser extent, anxiety symptoms.

To assess the impact of maternal, neonatal, and adolescent factors on the development of non-alcoholic fatty liver disease (NAFLD) in a cohort of 14- to 19-year-old adolescents. This study is part of the Early Vascular Ageing in the YOUth study, a single-center cross-sectional study conducted in western Austria. Maternal and neonatal factors were extracted from the mother-child booklet, adolescent factors were evaluated by a face-to-face interview, physical examination, and fasting blood analyses. Liver fat content was assessed by controlled attenuation parameter (CAP) using signals acquired by FibroScan® (Echosense, Paris, France). The association of maternal, neonatal, and adolescent factors with CAP values was analyzed using linear regression models. In total, 595 adolescents (27.2% male) aged 17.0 ± 1.3 years were included. 4.9% (n = 29) showed manifest NAFLD with CAP values above the 90th percentile. Male sex (p < 0.001), adolescent triglyceride levels (p = 0.021), Homeostatic Model Assessment for Insulin Resistance index and BMI z-score (p < 0.001, each) showed a significant association with liver fat content in the multivariable analysis. Maternal pre-pregnancy BMI was associated with CAP values after adjustment for sex, age, and birth weight for gestational age (p < 0.001), but this association was predominantly mediated by adolescent BMI (indirect effect b = 1.18, 95% CI [0.69, 1.77]). Components of the metabolic syndrome were the most important predictors of adolescent liver fat content. Therefore, prevention of NAFLD should focus on lifestyle modification in childhood and adolescence.

ObjectivesArterial stiffness as assessed by pulse wave velocity (PWV) improves the prediction of first-ever and recurring stroke and of stroke outcomes when measured in the days after stroke. Here, we investigated the longitudinal dynamics of PWV in the days after acute ischaemic stroke.DesignMonocentric, prospective cohort study nested within a clinical trial registry with repeated measurement assessment of PWV.SettingComprehensive middle European stroke centre.Participants20 men and women that suffered stroke from November 2022 through August 2023.Primary and secondary outcome measuresChange in carotid-femoral PWV was investigated by recording PWV four times between 1.2 and 9.9 days after stroke using a Vicorder device. Haemodynamic and patient-, stroke- and care-related variables were investigated as potential modifiers of PWV trajectories.ResultsTwenty patients aged 61.3±16.9 years (14 males) were included. There was a daily decline in PWV of −0.19 m/s (95% CI: −0.29 to –0.09; p<0.001) until approximately 8 days after stroke, corresponding to a total relative decline of −15.5% (95% CI: -22.3 to –8.1; p<0.001). Whereas higher anxiety predicted 0.11 m/s (95% CI: 0.01 to 0.20; p=0.044) slower daily decline, decline was not significantly related to baseline PWV, blood pressures, stroke severity or location, or functional status (all p>0.05). Rank-order correlation between the earliest and latest PWV measurements was 0.87 (95% CI: 0.69 to 0.95; p<0.001).ConclusionsA marked decline in PWV during the first week after acute ischaemic stroke should be accounted for when interpreting PWV after recent stroke.Trial registration numberThe STROKE-CARD Registry was registered at ClinicalTrials.gov (NCT04582825).

(1) Background: Unhealthy dietary behaviors are estimated to be one of the leading causes of death globally and are often shaped at a young age. Here, we investigated adolescent diet quality and its predictors, including nutrition knowledge, in two large Central European cohorts. (2) Methods: In 3056 participants of the EVA-Tyrol and EVA4YOU prospective population-based cohort studies aged 14 to 19 years, diet quality was assessed using the AHEI-2010 and DASH scores, and nutrition knowledge was assessed using the questionnaire from Turconi et al. Associations were examined utilizing multivariable linear regression. (3) Results: The mean overall AHEI-2010 score was 42%, and the DASH score was 45%. Female participants (60.6%) had a significantly higher diet quality according to the AHEI-2010 and DASH score. AHEI-2010 and DASH scores were significantly associated (p < 0.001) with sex, school type, smoking, and total daily energy intake. The DASH score was additionally significantly associated (p < 0.001) with age, socioeconomic status, and physical activity. Participants with better nutrition knowledge were more likely to be older, to attend a general high school, to live in a high-income household, to be non-smokers, and to have a higher diet quality according to the AHEI-2010 and DASH score. (4) Conclusions: Predictors of better diet quality included female sex, physical activity, educational level, and nutrition knowledge. These results may aid focused interventions to improve diet quality in adolescents.

Background Migraine with aura is associated with an increased risk of cardiovascular disease, yet the pathophysiology is unknown. Suggested underlying mechanisms of aura formation point into the direction of an abnormal vasoreactivity that also extends to the extracranial vasculature. Methods In the Early Vascular Ageing Tyrol study, a community-based non-randomized controlled trial conducted in 45 schools and companies in Tyrol (Austria) and South-Tyrol (Italy) between May 2015 and September 2018 aiming to increase cardiovascular health in adolescents, headache syndromes were classified according to the International Classification of Headache Disorders in a face-to-face interview. Carotid-femoral pulse-wave-velocity was measured by applanation tonometry and carotid intima-media-thickness by high-resolution ultrasound of the distal common carotid arteries. Differences in pulse-wave-velocity and carotid intima-media-thickness in youngsters with migraine with aura were compared respectively to those without headache and with other headaches by multivariable linear regression analysis. Results Of the 2102 study participants 1589 were aged 14 to 19 (mean 16.8) years and had complete data. 43 (2.7%) reported migraine with aura and 737 (46.4%) other headaches. Mean pulse-wave-velocity was 6.17 m/s (± 0.85) for migraine with aura, 6.06 m/s (± 0.82) for all other headaches and 6.15 (0.95) m/s for participants without headaches. Carotid intima-media-thickness was 411.3 µm (± 43.5) for migraine with aura, 410.9 µm (± 46.0) for all other headaches and 421.6 µm (± 48.4) for participants without headaches. In multivariable linear regression analysis, we found no differences in carotid-femoral pulse-wave-velocity or carotid intima-media-thickness in young subjects with migraine with aura, all other headaches, or no headaches. Conclusions In line with previous large-scale studies in adults, we could not demonstrate relevant associations of migraine with aura with markers of arterial stiffness or subclinical atherosclerosis making early vascular ageing an unlikely pathophysiological link between migraine with aura and cardiovascular diseases.

Background Patients with ischaemic stroke or transient ischaemic attack (TIA) are at high risk of incident cardiovascular events and recurrent stroke. Despite compelling evidence about the efficacy of secondary prevention, a substantial gap exists between risk factor management in real life and that recommended by international guidelines. We conducted the STROKE-CARD trial (NCT02156778), a multifaceted pragmatic disease management program between 2014 and 2018 with follow-up until 2019. This program successfully reduced cardiovascular risk and improved health-related quality of life and functional outcome in patients with acute ischaemic stroke or TIA within 12 months after the index event. To investigate potential long-term effects of STROKE-CARD care compared to standard care, an extension of follow-up is warranted. Methods We aim to include all patients from the STROKE-CARD trial (n = 2149) for long-term follow-up between 2019 and 2021 with the study visit scheduled 3–6 years after the stroke/TIA event. The co-primary endpoint is the composite of major recurrent cardiovascular events (nonfatal stroke, nonfatal myocardial infarction, and vascular death) from hospital discharge until the long-term follow-up visit and health-related quality of life measured with the European Quality of Life-5 Dimensions (EQ-5D-3L) at the final visit. Secondary endpoints include overall mortality, long-term functional outcome, and target-level achievement in risk factor management. Discussion This long-term follow-up will provide evidence on whether the pragmatic post-stroke/TIA intervention program STROKE-CARD is capable of preventing recurrent cardiovascular events and improving quality-of-life in the long run.

According to the World Health Organization, cardiovascular diseases (CVDs) are the leading non-communicable cause of death. Awareness of the individual risk profile is crucial to implement a healthy lifestyle and prevent CVDs. Multiple studies demonstrated that atherosclerosis, the main cause of CVDs, begins early in life. Therefore, it may be necessary to start prevention programs already in childhood. The EVA-Tyrol study is a population-based non-randomized controlled trial that will prospectively enroll 2000 participants from high schools and training companies in North- and East-Tyrol (Austria) and South-Tyrol (Italy). Participants will be assigned to either an intervention (n = 1500) or a control (n = 500) group. Intervention group participants will be enrolled at the 10th school grade (mean age 15-16 years), undergo two examinations within a two-year interval, with follow-up at the 12th grade (mean ages 17-18 years). Control group participants will be enrolled at the 12th grade (mean age 17-18 years). Medical examination will include anthropometric measurements, comprehensive lifestyle and dietary questionnaires, a fasting blood sample, high-resolution ultrasound of the carotid arteries, and measurement of carotid-femoral pulse wave velocity. Active intervention will consist of (1) enhancing knowledge about CVDs, (2) individual medical counseling based on the results of the baseline examination, (3) an online health promotion tool and (4) involvement of participants in planning and implementation of health promotion projects. Effectiveness of the intervention will be assessed by comparing the proportion subjects with ideal health metrics as defined by the American Heart Association between study groups. This study aims to improve cardiovascular health in Tyrolean adolescents by demonstrating the efficacy of a multi-layer health promotion program and may yield novel insights into the prevalence of vascular risk conditions and mechanisms of early vascular pathologies in adolescents.

Although extracranial internal carotid artery (e-ICA) occlusion is a common pathology in patients undergoing intravenous thrombolysis for treatment of acute ischemic stroke, no data on e-ICA recanalization rate or potential effects on outcome are yet available. This study included 52 consecutive patients with e-ICA occlusion and ischemic stroke undergoing standard intravenous thrombolysis. The rate of e-ICA recanalization was 30.8% [95%CI, 18.2-43.3], documented at 3.5 [2.0-11.8] (median [IQR]) days after stroke, as compared to 8.6% [95%CI, 3.5-13.7] in a series of 116 consecutive patients with symptomatic e-ICA occlusion not undergoing thrombolysis (P<0.001 for difference). Functional outcome three months after stroke did not significantly differ for those with or without e-ICA recanalization following intravenous thrombolysis (modified Rankin scale ≤2: 31.3% vs. 22.2%, odds ratio 1.6 [95%CI, 0.4-5.9], P = 0.506). In patients with e-ICA occlusion of atherothrombotic origin, recanalization resulted in most instances in residual high-grade stenosis (13 of 14). Recanalization of e-ICA occlusion after stroke thrombolysis occurred in about one third of patients. Although e-ICA recanalization had no significant effect on patient outcome, control sonography in the early days after thrombolysis is recommended for the detection of potential residual e-ICA stenosis.
