Introduction: Dysphagia is common after acute ischemic stroke and entails considerable morbidity and mortality. Here, we investigated the impact of intensified care on swallowing recovery after stroke., Patients and Methods: In this secondary analysis of STROKE-CARD, a randomized intervention trial of intensified post-stroke care, dysphagia was assessed by speech therapists at admission for acute ischemic stroke, at hospital discharge, and after 12-months. Patients randomized to STROKE-CARD care additionally received a detailed dysphagia follow-up at 3-months, including a standardized dysphagia examination, instructions on further exercises and compensation mechanisms and, if necessary, referral for further speech therapy., Results: Dysphagia was present initially after stroke in 236 (16.6%; median age 82 (73-88), 44.1% female) of 1419 patients, with similar prevalence in both study groups at hospital admission ( p  = 0.239) and discharge ( p  = 0.870). At follow up, 14 (9.5%) of 147 in the intervention group and 18 (20.2%) of 89 in the control group suffered from persistent dysphagia ( p  = 0.020). There was better dysphagia recovery in the intervention group also under multivariable adjustment for age, sex, functional disability at 12-months, severe dysphagia at hospitalization, mode of feeding, cognitive impairment, thrombolysis, and stroke localization (odds ratio, 0.41, 95% confidence interval: 0.17 to 0.96)., Discussion and Conclusion: Intensified post-stroke care improved dysphagia recovery within 1 year after acute ischemic stroke, highlighting the potential of targeted interventions for enhancing stroke outcomes., Competing Interests: Declaration of conflicting interestThe author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: PW reports consultancy fees from Novartis Pharmaceuticals unrelated to this manuscript.

Background: Pre-existing comorbidities increase the likelihood of post-stroke dysphagia. This study investigates comorbidity prevalence in patients with dysphagia after ischemic stroke., Methods: The data of patients with acute ischemic stroke from two large representative cohorts (STROKE-CARD trial 2014-2019 and STROKE-CARD registry 2020-2022 - both study center Innsbruck, Austria) were analyzed for the presence of dysphagia at hospital admission (clinical swallowing examination). Comorbidities were assessed using the Charlson Comorbidity Index (CCI)., Results: Of 2054 patients with ischemic stroke, 17.2% showed dysphagia at hospital admission. Patients with dysphagia were older (77.8 ± 11.9 vs. 73.6 ± 14.3 years, p < 0.001), had more severe strokes (NIHSS 7(4-12) vs. 2(1-4), p < 0.001) and had higher CCI scores (4.7 ± 2.1 vs. 3.8 ± 2.0, p < 0.001) than those without swallowing impairment. Dysphagia correlated with hypertension (p = 0.034), atrial fibrillation (p < 0.001), diabetes (p = 0.002), non-smoking status (p = 0.014), myocardial infarction (p = 0.002), heart failure (p = 0.002), peripheral arterial disease (p < 0.001), severe chronic liver disease (p = 0.002) and kidney disease (p = 0.010). After adjusting for relevant factors, the associations with dysphagia remained significant for diabetes (p = 0.005), peripheral arterial disease (p = 0.007), kidney disease (p = 0.014), liver disease (p = 0.003) and overall CCI (p < 0.001)., Conclusions: Patients with multiple comorbidities have a higher risk of developing post-stroke dysphagia. Therefore, early and thorough screening for swallowing impairment after acute ischemic stroke is crucial especially in those with multiple concomitant diseases., Trial Registration: Stroke Card Registry (NCT04582825), Stroke Card Trial (NCT02156778)., (© 2024.

Background and Purpose: 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., Methods: 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., Results: 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., Conclusions: 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., (© 2024 The Authors.

The objectives of this study were to develop age- and sex-specific reference percentiles for fat mass index (FMI) and fat-free mass index (FFMI) in adolescents aged 14 to 19 years and to determine differences in overweight/obesity classification by FMI and body mass index (BMI). The EVA4YOU study is a single-center cross-sectional study conducted in western Austria. Cardiovascular risks including anthropometric measurements and bioelectrical impedance analysis were assessed in adolescents (mean age 17 years). FMI and FFMI were calculated as the ratio of fat mass (FM) and fat-free mass (FFM) to the square of height and compared to study population-specific BMI percentiles. One thousand four hundred twenty-two adolescents were included in the analysis. Girls had a significantly higher mean FM and FMI and a significantly lower mean FFM, FFMI (p < 0.001, each), and mean BMI (p = 0.020) than boys. Body composition classification by FMI and BMI percentiles shows a concordance for the < 75th and > 97th percentile, but a significant difference in percentile rank classifications between these two cut-off values (all p < 0.05). Based on FMI, 15.5% (221/1422) of the whole population and 29.4% (92/313) of those between the 75th and 97th percentiles are classified one category higher or lower than those assigned by BMI., Conclusion:  Classification of normal or pathologic body composition based on BMI and FMI shows good accordance in the clearly normal or pathologic range. In an intermediate range, FMI reclassifies categories based on BMI in more than a quarter of adolescents. Cut-off values to differentiate normal from pathologic FMI values on a biological basis are needed., Trial Registration: The study is registered at www., Clinicaltrials: gov  (Identifier: NCT04598685; Date of registration: October 22, 2020)., What Is Known: • Chronic non-communicable diseases (NCDs) are the leading cause of morbidity and mortality globally, with major risk factors including unhealthy diets, harmful behaviors, and obesity. Obesity in children and adolescents is a key risk factor for later NCDs, which is commonly measured by Body Mass Index (BMI). • BMI can be misleading as it doesn't distinguish between fat mass (FM) and fat-free mass (FFM), leading to potential misclassification of obesity in children. Previous studies have already suggested the use of the Fat Mass Index (FMI) and Fat-Free Mass Index (FFMI) as a more accurate measures of body composition., What Is New: • This study adds the first age- and sex-specific reference values for FMI and FFMI in Austrian adolescents using bioelectrical impedance analysis (BIA) as a safe and secure measurement method of a large representative cohort. • We found percentile misclassification between BMI and FMI when categorizing for obesity, especially in intermediate categories of body composition. Furthermore, when comparing the new reference values for FMI and FFMI to existing ones from the US, UK, and Germany we could show a good alignment within the European cohorts and major differences with American values, indicating and confirming the difference of FMI and FFMI for different populations of different ethnical background, living on different continents., (© 2024.

Background and Purpose: Biological sex is known to have an impact on quality metrics of acute stroke. We aimed to determine whether COVID positivity accentuates this effect and constitutes worse outcome., Methods: The present analysis was based on the Global COVID-19 Stroke Registry, a retrospective, international, cohort study of consecutive ischemic stroke patients receiving intravenous thrombolysis and/or endovascular thrombectomy between 1 March 2020 and 30 June 2021. We investigated differences between the sexes in patient characteristics, acute stroke metrics as well as post-stroke outcome in COVID-positive and COVID-negative stroke patients undergoing acute revascularization procedures., Results: A total of 15,128 patients from 106 centers were recorded in the Global COVID-19 Stroke Registry, 853 (5.6%) of whom were COVID-positive. Overall, COVID-positive individuals were treated significantly slower according to every acute stroke metric compared to COVID-negative patients. We were able to show that key quality indicators in acute stroke treatment were unfavorable for COVID-negative women compared to men (last-seen-well-to-door time + 11 min in women). Furthermore, COVID-negative women had worse 3-month outcomes (3-month modified Rankin Scale score [interquartile range] 3.0 [4.0] vs. 2.0 [3.0]; p < 0.01), even after adjusting for confounders. In COVID-positive individuals no such difference between the sexes, either in acute management metrics or in 3-month outcome, was seen., Conclusion: Known sex-related differences in acute stroke management exist and extend to times of crisis. Nevertheless, if patients were COVID-19-positive at stroke onset, women and men were treated the same, which could be attributed to structured treatment pathways., (© 2024 The Authors.

Aim: 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., Methods: 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., Results: 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])., Conclusion: 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., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Nairz et al.

Background: Dyslipidemia is an independent risk factor for coronary heart disease (CHD). Standard lipid panel cannot capture the complexity of the blood lipidome (ie, all molecular lipids in the blood). To date, very few large-scale epidemiological studies have assessed the full spectrum of the blood lipidome on risk of CHD, especially in a longitudinal setting., Methods and Results: Using an untargeted liquid chromatography-mass spectrometry, we repeatedly measured 1542 lipid species from 1835 unique American Indian participants who attended 2 clinical visits (≈5.5 years apart) and followed up to 17.8 years in the Strong Heart Family Study (SHFS). We first identified baseline lipid species associated with risk of CHD, followed by replication in a European population. The model adjusted for age, sex, body mass index, smoking, hypertension, diabetes, low-density lipoprotein cholesterol, estimated glomerular filtration rate, education, and physical activity at baseline. We then examined the longitudinal association between changes in lipid species and changes in cardiovascular risk factors during follow-up. Multiple testing was controlled by the false discovery rate. We found that baseline levels of multiple lipid species (eg, phosphatidylcholines, phosphatidylethanolamines, and ceramides) were associated with the risk of CHD and improved the prediction accuracy over conventional risk factors in American Indian people. Some identified lipids in American Indian people were replicated in European people. Longitudinal changes in multiple lipid species (eg, acylcarnitines, phosphatidylcholines, and triacylglycerols) were associated with changes in cardiovascular risk factors., Conclusions: Baseline plasma lipids and their longitudinal changes over time are associated with risk of CHD. These findings provide novel insights into the role of dyslipidemia in CHD.

Background: Initiation of SARS-CoV-2 (Severe acute respiratory syndrome coronavirus type 2) vaccinations aroused scepticism within the general-public about risks including stroke. Our aim was to explore temporal associations between vaccination and cerebrovascular events through an analysis of a prospective large-scale cohort of consecutive stroke and high-risk TIA (transitory ischaemic attack) patients., Methods: We prospectively recruited a cohort of consecutive ischaemic stroke and high-risk TIA (ABCD2-Score ≥ 4) patients treated at the Innsbruck University Hospital (STROKE-CARD Registry Study, NCT04582825) from December 2020 until February 2022. SARS-CoV-2 vaccination status and the time of administration was ascertained by electronic health-data. A Cox model with vaccination status as time-dependent co-variable was employed to examine its association with ischaemic events., Results: Data on 572 participants were available with 355 (62.1%) vaccinated against SARS-CoV-2 before suffering cerebral ischaemia. In our cohort, no temporal association between vaccination and cerebrovascular event was detected (HR 1.06 [0.85-1.34; p = 0.60]) and this also applies to TIA (HR [0.82 0.37-1.85; p = 0.64]) or minor stroke (HR 1.18 [0.89-1.56; p = 0.26]) and subgroups defined by sex and age. Neither vector-based (HR 1.11 [0.79-1.56; p = 0.55]) nor mRNA-based (HR 1.06 [0.84-1.34; p = 0.61]) vaccinations were associated with the occurrence of cerebral ischaemia., Conclusion: Among patients with stroke or high-risk TIA, SARS-CoV-2 vaccination was not associated with cerebral ischaemia., Competing Interests: Declaration of Competing Interest The authors have no competing interests to report., (Copyright © 2023.

(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., Trial Registration: First registered on ClinicalTrials.gov 29/04/2019 (NCT03929692)., (© 2023.

Background: Homocysteine (Hcy) has been associated with an adverse cardiovascular risk profile in adolescents. Assessment of the association between plasma Hcy levels and clinical/laboratory factors might improve our understanding of the pathogenesis of cardiovascular disease., Methods: Hcy was measured in 1,900 14- to 19-year-old participants of prospective population-based EVA-TYROL Study (44.3% males, mean age 16.4 years) between 2015 and 2018. Factors associated with Hcy were assessed by physical examination, standardized interviews, and fasting blood analysis., Results: Mean plasma Hcy was 11.3 ± 4.5 µmol/L. Distribution of Hcy was characterized by extreme right skew. Males exhibited higher Hcy and sex differences increased with increasing age. Univariate associations with Hcy emerged for age, sex, body mass index, high-density lipoprotein cholesterol, and for factors pertaining to blood pressure, glucose metabolism, renal function, and diet quality, whereas the most important multivariate predictors of Hcy were sex and creatinine., Discussion: Clinical and laboratory factors associated with Hcy in adolescents were manifold, with sex and high creatinine identified as strongest independent determinants. These results may aid when interpreting future studies investigating the vascular risk of homocysteine., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2023 Gande, Hochmayr, Staudt, Bernar, Stock, Kiechl, Geiger, Griesmacher, Scholl-Bürgi, Knoflach, Pechlaner, Kiechl-Kohlendorfer and the (Early Vascular Ageing) EVA Study Group.)

Background: Arterial stiffening is central to the vascular ageing process and a powerful predictor and cause of diverse vascular pathologies and mortality. We investigated age and sex trajectories, regional differences, and global reference values of arterial stiffness as assessed by pulse wave velocity (PWV)., Methods: Measurements of brachial-ankle or carotid-femoral PWV (baPWV or cfPWV) in generally healthy participants published in three electronic databases between database inception and August 24th, 2020 were included, either as individual participant-level or summary data received from collaborators (n = 248,196) or by extraction from published reports (n = 274,629). Quality was appraised using the Joanna Briggs Instrument. Variation in PWV was estimated using mixed-effects meta-regression and Generalized Additive Models for Location, Scale, and Shape., Findings: The search yielded 8920 studies, and 167 studies with 509,743 participants from 34 countries were included. PWV depended on age, sex, and country. Global age-standardised means were 12.5 m/s (95% confidence interval: 12.1-12.8 m/s) for baPWV and 7.45 m/s (95% CI: 7.11-7.79 m/s) for cfPWV. Males had higher global levels than females of 0.77 m/s for baPWV (95% CI: 0.75-0.78 m/s) and 0.35 m/s for cfPWV (95% CI: 0.33-0.37 m/s), but sex differences in baPWV diminished with advancing age. Compared to Europe, baPWV was substantially higher in the Asian region (+1.83 m/s, P = 0.0014), whereas cfPWV was higher in the African region (+0.41 m/s, P < 0.0001) and differed more by country (highest in Poland, Russia, Iceland, France, and China; lowest in Spain, Belgium, Canada, Finland, and Argentina). High vs. other country income was associated with lower baPWV (-0.55 m/s, P = 0.048) and cfPWV (-0.41 m/s, P < 0.0001)., Interpretation: China and other Asian countries featured high PWV, which by known associations with central blood pressure and pulse pressure may partly explain higher Asian risk for intracerebral haemorrhage and small vessel stroke. Reference values provided may facilitate use of PWV as a marker of vascular ageing, for prediction of vascular risk and death, and for designing future therapeutic interventions., Funding: This study was supported by the excellence initiative VASCage funded by the Austrian Research Promotion Agency, by the National Science Foundation of China, and the Science and Technology Planning Project of Hunan Province.

Extensive scientific and clinical microbiome studies have explored contemporary variation and dynamics of the gut microbiome in human health and disease 1-3 , yet the role of long-term life history effects has been underinvestigated. Here, we analyzed the current, quantitative microbiome composition in the older adult Bruneck Study cohort (Italians, Bruneck, n = 304 (male, 154; female, 150); age 65-98 years) with extensive clinical, demographic, lifestyle and nutritional data collected over the past 26 years 4 . Multivariate analysis of historical variables indicated that medication history, historical physical activity, past dietary habits and specific past laboratory blood parameters explain a significant fraction of current quantitative microbiome variation in older adults, enlarging the explanatory power of contemporary covariates by 33.4%. Prediction of current enterotype by a combination of past and contemporary host variables revealed good levels of predictability (area under the curve (AUC), 0.78-0.83), with Prevotella and dysbiotic Bacteroides 2 being the best predicted enterotypes. These findings demonstrate long-term life history effects on the microbiota and provide insights into lifestyle variables and their role in maintaining a healthy gut microbiota in later life., (© 2022.

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.

Introduction: Mortality in children with hemato-oncologic disease admitted to a pediatric intensive care unit (PICU) is higher compared to the general population. The reasons for this fact remain unexplored. The aim of this study was to assess outcomes and trends in hemato-oncologic patients admitted to a PICU, with analytical emphasis on emergency admissions., Methods: Patients with a hemato-oncologic diagnosis admitted to a tertiary care university hospital PICU between 1 January 2009 and 31 December 2019 were retrospectively analyzed. Additionally, patient mortality 6 months after PICU admission and follow-up mortality until 31 December 2020 were recorded., Measurements and Main Results: We reviewed a total of 701 PICU admissions of 338 children with hemato-oncologic disease, of which 28.5% were emergency admissions with 200 admissions of 122 patients. Of these, 22 patients died, representing a patient mortality of 18.0% and an admission mortality of 11.0% in this group. Follow-up patient mortality was 25.4% in emergency-admitted children. Multivariable analysis revealed severe neutropenia at admission and invasive mechanical ventilation (IMV) as independent risk factors for PICU death ( p = 0.029 and p = 0.002). The total number of PICU admissions of hemato-oncologic patients rose notably over time, from 44 in 2009 to 125 in 2019., Conclusion: Although a high proportion of emergency PICU admissions of hemato-oncologic patients required intensive organ support, mortality seemed to be lower than previously reported. Moreover, in this study, total PICU admissions of the respective children rose notably over time., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Pechlaner, Kropshofer, Crazzolara, Hetzer, Pechlaner and Cortina.)

Background and Aims: Matrix Gla protein (MGP), a vitamin K-dependent protein, is a potent inhibitor of vascular calcification. Desphospho-uncarboxylated MGP (dp-ucMGP), a marker of vitamin K insufficiency, has been shown to predict cardiovascular disease (CVD) and all-cause mortality in high-risk populations. Whether the increased risk associated with dp-ucMGP also applies to the general, and especially, the elderly population has not yet been fully elucidated., Methods and Results: Plasma dp-ucMGP was measured in 684 individuals aged 50-89 years of the prospective population-based Bruneck Study (baseline evaluation in 2000). Baseline median dp-ucMGP was 478.4 (IQR 335.0-635.2) pmol/L. Over a median follow-up of 15.5 years, 163 CVD events occurred and 235 participants died. Age-/sex-adjusted hazard ratios (HRs) per 1-SD higher level of log e transformed dp-ucMGP were 1.30 (95%CI: 1.09-1.55; p=0.004) for incident CVD and 1.36 (95%CI: 1.17-1.57; p<0.001) for all-cause mortality. After multivariable adjustment, the associations remained significant with HRs of 1.23 (95%CI: 1.02-1.47, p=0.029) for CVD and 1.40 (95%CI: 1.20-1.64; p<0.001) for all-cause mortality. The associations remained virtually unchanged after additional adjustment for dietary quality as measured with the Alternative Healthy Eating Index. We found no association of dp-ucMGP with myocardial infarction and sudden cardiac deaths, but a strong association with other vascular deaths and non-vascular/non-cancer deaths., Conclusions: This study shows a significant association of plasma dp-ucMGP with incident CVD and a significant and even stronger association with all-cause mortality. Clinical trials are needed to investigate whether vitamin K substitution results in improved health outcomes., (Copyright © 2022 The Authors. Published by Elsevier B.V. All rights reserved.)

Background and Aims: Assessment of comprehensive lipoprotein subclass profiles in adolescents and their relation to vascular disease may enhance our understanding of the development of dyslipidemia in early life and inform early vascular prevention., Methods: Nuclear magnetic resonance was used to measure lipoprotein profiles, including lipids (cholesterol, free cholesterol, triglycerides, phospholipids) and apolipoproteins (apoB-100, apoA1, apoA2) of 17 lipoprotein subclasses (from least dense to densest: VLDL-1 to -6, IDL, LDL-1 to -6, HDL-1 to -4) in n = 1776 14- to 19-year olds (56.6% female) and n = 3027 25- to 85-year olds (51.5% female), all community-dwelling. Lipoprotein profiles were related to carotid intima-media thickness (cIMT) as ascertained by sonography., Results: Adolescents compared to adults had lower triglycerides, total, LDL, and non-HDL cholesterol, and apoB, and higher HDL cholesterol. They showed 26.6-59.8% lower triglyceride content of all lipoprotein subclasses and 21.9-51.4% lower VLDL lipid content. Concentrations of dense LDL-4 to LDL-6 were 36.7-40.2% lower, with also markedly lower levels of LDL-1 to LDL-3, but 24.2% higher HDL-1 ApoA1. In adolescents, only LDL-3 to LDL-5 subclasses were associated with cIMT (range of differences in cIMT for a 1-SD higher concentration, 4.8-5.9 μm). The same associations emerged in adults, with on average 97 ± 42% (mean ± SD) larger effect sizes, in addition to LDL-1 and LDL-6 (range, 6.9-11.3 μm) and HDL-2 to HDL-4, ApoA1, and ApoA2 (range, -7.0 to -17.7 μm)., Conclusions: Adolescents showed a markedly different and more favorable lipoprotein profile compared to adults. Dense LDL subclasses were the only subclasses associated with cIMT in adolescents, implicating them as the potential preferred therapeutic target for primary prevention of cardiovascular disease at this age. In adults, associations with cIMT were approximately twice as large as in adolescents, and HDL-related measures were additionally associated with cIMT., (Copyright © 2021 Elsevier B.V.

Purpose: A significant proportion of noncommunicable diseases in adults has its roots in adolescence, and this is particularly true for cardiovascular disease and stroke. Detection of vascular and metabolic risk factors at young ages may aid disease prevention., Methods: In 2,088 adolescents sampled from the general population of Tyrol, Austria, and South Tyrol, Italy, we systematically assessed the frequency of yet unknown vascular and metabolic risk conditions that require further diagnostic workup or intervention (lifestyle counselling or pharmacotherapy). The health screening included medical history taking, fasting blood analysis, and blood pressure and body measurements and was performed at schools. To recruit a representative sample of adolescents, equal proportions (about 67%) of schools were invited per school type and region., Results: Adolescents were on average 16.4 (standard deviation 1.1) years old, and 56.4% were female. A proportion of 22.8% (95% confidence interval [CI], 19.6-26.3) had previous or current physician-confirmed diseases. The health screening newly detected relevant medical conditions in 45.4% [95% CI, 41.5-49.4] (55.8% [95% CI, 52.7-58.7] in boys and 37.4% [95% CI, 35.0-39.8] in girls, p < .001). The most prevalent were elevated blood pressure and hypertension, metabolic syndrome, hypercholesterolemia, hypertriglyceridemia, hyperuricemia, and subclinical hypothyroidism. Detection of risk conditions did not depend on socioeconomic status but increased with age and body mass index., Conclusions: Vascular health screening in adolescents at schools has a high diagnostic yield and may aid guideline-recommended prevention in the youth. Implementation should carefully consider national differences in healthcare systems, resources, and existing programs., (Copyright © 2021 Society for Adolescent Health and Medicine.

Rationale: Proprotein convertase subtilisin/kexin type 9 (PCSK9) circulates in a free and lipoprotein-bound form, yet the functional consequence of the association between PCSK9 and high-density lipoprotein (HDL) remains unexplored., Objective: This study sought to interrogate the novel relationship between PCSK9 and HDL in humans., Methods and Results: Comparing lipoprotein and apolipoprotein profiles by nuclear magnetic resonance and targeted mass spectrometry measurements with PCSK9 levels in the community-based Bruneck (n=656) study revealed a positive association of plasma PCSK9 with small HDL, alongside a highly significant positive correlation between plasma levels of PCSK9 and apolipoprotein-C3, an inhibitor of lipoprotein lipase. The latter association was replicated in an independent cohort, the SAPHIR study (n=270). Thus, PCSK9-HDL association was determined during the postprandial response in two dietary studies (n=20 participants each, 8 times points). Peak triglyceride levels coincided with an attenuation of the PCSK9-HDL association, a loss of apolipoprotein-C3 from HDL and lower levels of small HDL as measured by nuclear magnetic resonance. Crosslinking mass spectrometry (XLMS) upon isolated HDL identified PCSK9 as a potential HDL-binding partner. PCSK9 association with HDL was confirmed through size-exclusion chromatography and immuno-isolation. Quantitative proteomics upon HDL isolated from patients with coronary artery disease (n=172) returned PCSK9 as a core member of the HDL proteome. Combined interrogation of the HDL proteome and lipidome revealed a distinct cluster of PCSK9, phospholipid transfer protein, clusterin and apolipoprotein-E within the HDL proteome, that was altered by sex and positively correlated with sphingomyelin content. Mechanistically, HDL facilitated PCSK9-mediated low-density lipoprotein receptor degradation and reduced low-density lipoprotein uptake through the modulation of PCSK9 internalisation and multimerisation., Conclusions: This study reports HDL as a binder of PCSK9 and regulator of its function. The combination of -omic technologies revealed postprandial lipaemia as a driver of PCSK9 and apolipoprotein-C3 release from HDL.

Background Cardiovascular disease depends on the duration and time course of risk factor exposure. Previous reports on risk factors of progression of carotid intima-media thickness (cIMT) in the young were mostly restricted to high-risk populations or susceptible to certain types of bias. We aimed to unravel a risk factor signature for early vessel pathology based on repeated ultrasound assessments of the carotid arteries in the general population. Methods and Results Risk factors were assessed in 956 adolescents sampled from the general population with a mean age of 15.8±0.9 years, 56.2% of whom were female. cIMT was measured at baseline and on average 22.5±3.4 months later by high-resolution ultrasound. Effects of baseline risk factors on cIMT progression were investigated using linear mixed models with multivariable adjustment for potential confounders, which yielded significant associations (given as increase in cIMT for a 1-SD higher baseline level) for alanine transaminase (5.5 μm; 95% CI: 1.5-9.5), systolic blood pressure (4.7 μm; 0.3-9.2), arterial hypertension (9.5 μm, 0.2-18.7), and non-high-density (4.5 μm; 0.7-8.4) and low-density lipoprotein cholesterol (4.3 μm; 0.5-8.1). Conclusions Systolic blood pressure, arterial hypertension, low-density and non-high-density lipoprotein cholesterol, and alanine transaminase predicted cIMT progression in adolescents, even though risk factor levels were predominantly within established reference ranges. These findings reemphasize the necessity to initiate prevention early in life and challenge the current focus of guideline recommendations on high-risk youngsters.

Decreased cognitive performance is a hallmark of brain aging, but the underlying mechanisms and potential therapeutic avenues remain poorly understood. Recent studies have revealed health-protective and lifespan-extending effects of dietary spermidine, a natural autophagy-promoting polyamine. Here, we show that dietary spermidine passes the blood-brain barrier in mice and increases hippocampal eIF5A hypusination and mitochondrial function. Spermidine feeding in aged mice affects behavior in homecage environment tasks, improves spatial learning, and increases hippocampal respiratory competence. In a Drosophila aging model, spermidine boosts mitochondrial respiratory capacity, an effect that requires the autophagy regulator Atg7 and the mitophagy mediators Parkin and Pink1. Neuron-specific Pink1 knockdown abolishes spermidine-induced improvement of olfactory associative learning. This suggests that the maintenance of mitochondrial and autophagic function is essential for enhanced cognition by spermidine feeding. Finally, we show large-scale prospective data linking higher dietary spermidine intake with a reduced risk for cognitive impairment in humans., Competing Interests: Declaration of interests F.M., S.J.S., and D.C.-G. have equity interests in The Longevity Labs (TLL), a company founded in 2016 that develops natural food extracts.

Background and Aims: Ideal cardiovascular health (CVH) behaviors in adolescents are defined by body mass index (BMI), diet, physical activity and smoking, and are directly associated with better health in later life. To further improve health prevention programs we investigated the prevalence of these behaviors in a cohort of healthy adolescents and focused on the associations with sex, age, and education., Methods and Results: The Early Vascular Aging Tyrol study is a cross-sectional study assessing 14- to 19-year-old pupils and apprentices in Western Austria and South Tyrol. Between May 2015 and July 2018 2047 adolescents (43.6% males, mean age 16.4 years) with complete data for all 4 health behaviors were included. The prevalence of ideal body mass index (BMI) was 78.3%, of ideal physical activity 42.5%, of non-smoking 70.4% and of ideal diet 8.1%. Females showed a higher smoking prevalence and a lower physical activity, but better dietary habits than males. Older adolescents of both sexes had lower prevalence of ideal smoking and diet. Apprentices and pupils of vocational schools had a higher BMI and a less favorable diet compared to secondary academic school students. Smoking prevalence was highest in apprentices. Non-ideal BMI was independently associated with smoking., Conclusion: In our cohort, only a minority showed ideal CVH behaviors which were best in adolescents younger than 16 years. We observed significant differences between males and females and a clear impact of school education with apprentices being at risk for non-ideal CVH behaviors., Clinical Trial Registration Number: NCT03929692, clinicaltrials.gov., Competing Interests: Declaration of competing interest The authors declare no conflicts of interest., (Copyright © 2020 The Italian Diabetes Society, the Italian Society for the Study of Atherosclerosis, the Italian Society of Human Nutrition and the Department of Clinical Medicine and Surgery, Federico II University.

Background: Premature birth entails an adverse cardiovascular risk profile, but the underlying mechanisms are insufficiently understood. Here, we employed an unbiased cardiovascular proteomics approach to profile former very preterm-born preschoolers., Methods: This observational study investigated differences in plasma concentrations of 79 proteins, including putative cardiovascular biomarkers between very preterm- and term-born children on average 5.5 years old (53.1% male) using multiple-reaction monitoring mass spectrometry., Results: Very preterm-born (n = 38; median gestational age 29.6 weeks) compared to term-born (n = 26; 40.2 weeks) children featured lower plasma concentrations of platelet factor 4 (PLF4; -61.6%, P < 0.0001), platelet basic protein (CXCL7; -57.8%, P < 0.0001), and hemoglobin subunit beta (-48.3%, P < 0.0001). Results remained virtually unchanged when adjusting for complete blood count parameters, including platelet count. Conversely, whole blood hemoglobin was higher (+7.62%, P < 0.0001) in preterm-born children., Conclusions: Very preterm birth was associated with decreased markers of platelet activation among preschoolers. These findings are consistent with reduced platelet reactivity persisting from very preterm birth to a preschool age., Impact: Former very preterm-born preschoolers featured reduced levels of platelet activation markers. While lower platelet reactivity in very preterm-born compared to term-born infants in the first days of life was established, it was unknown when, if at all, reactivity normalizes. The current study suggests that platelet hyporeactivity due to very preterm birth persists at least up to a preschool age. "Immaturity of the hemostatic system" may be a persistent sequel of preterm birth, but larger studies are needed to investigate its potential clinical implications.

Background: 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)., Methods: 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., Results: 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., Conclusion: 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., Competing Interests: Declaration of competing interest CS, NH, GB, IWC, KW, RP, UG, and MW report no disclosures.

Aims: Imbalances of iron metabolism have been linked to the development of atherosclerosis. However, subjects with hereditary haemochromatosis have a lower prevalence of cardiovascular disease. The aim of our study was to understand the underlying mechanisms by combining data from genome-wide association study analyses in humans, CRISPR/Cas9 genome editing, and loss-of-function studies in mice., Methods and Results: Our analysis of the Global Lipids Genetics Consortium (GLGC) dataset revealed that single nucleotide polymorphisms (SNPs) in the haemochromatosis gene HFE associate with reduced low-density lipoprotein cholesterol (LDL-C) in human plasma. The LDL-C lowering effect could be phenocopied in dyslipidaemic ApoE-/- mice lacking Hfe, which translated into reduced atherosclerosis burden. Mechanistically, we identified HFE as a negative regulator of LDL receptor expression in hepatocytes. Moreover, we uncovered liver-resident Kupffer cells (KCs) as central players in cholesterol homeostasis as they were found to acquire and transfer LDL-derived cholesterol to hepatocytes in an Abca1-dependent fashion, which is controlled by iron availability., Conclusion: Our results disentangle novel regulatory interactions between iron metabolism, KC biology and cholesterol homeostasis which are promising targets for treating dyslipidaemia but also provide a mechanistic explanation for reduced cardiovascular morbidity in subjects with haemochromatosis., (Published on behalf of the European Society of Cardiology.

Background and Aims: Atherosclerosis starts early in life. We aimed to assess the dimension and progression of the intima-media thickness, a surrogate marker for early vascular aging, and its association with a broad palette of cardiovascular risk and lifestyle factors in a large cohort of healthy adolescents., Methods: The EVA-Tyrol cohort study enrolled 1573 adolescents with a mean age of 16.0 years (SD 0.9). 1000 participants had a prospective follow-up after 22.1 months on average (SD 3.4). Cardiovascular risk and lifestyle factors were evaluated by standardized interviews, physical examination, and fasting blood analyses. Carotid intima-media thickness (cIMT) was measured at baseline and follow-up by high-resolution ultrasound. Aortic intima-media thickness (aIMT) was assessed during follow-up only., Results: Several vascular risk factors like elevated blood pressure (4.7% > 95th percentile), overweight (9.2% > 95th percentile) and smoking (29.7%) were already prevalent at this age. Maximum cIMT progressed by 2.78 μm (95% CI, 0.39-5.17) per year. In multivariable linear regression analysis, sex, body weight, systolic blood pressure, LDL-cholesterol and physical activity were independent predictors of cIMT both at baseline and follow-up. In addition, alanine-aminotransferase, a laboratory surrogate of non-alcoholic fatty liver disease, was independently associated with cIMT at follow-up and pack-years of smoking with aIMT., Conclusions: Unfavourable lifestyle and vascular risk factors were prevalent in adolescents and several of them were associated with vessel wall thickness, even though effect sizes were modest and cIMT variability was limited. These data suggest adolescence as a prime age range for early vascular prevention., Competing Interests: Declaration of competing interest The authors declared they do not have anything to disclose regarding conflict of interest with respect to this manuscript., (Copyright © 2020 Elsevier B.V.

There is evidence for the effects of platelet inhibition on innate immune activation. Circulating microRNAs (miRNAs) have been implicated as markers of platelet and leukocyte activation. In the present study, we assessed the effects of P2Y 12 inhibitors on platelet and leukocyte miRNAs during endotoxemia. Healthy volunteers were randomly assigned to receive oral ticagrelor ( n = 10), clopidogrel ( n = 8) or no drug ( n = 8) for one week, followed by an intravenous bolus of 2 ng/kg endotoxin. Serum was collected at baseline, after one week of antiplatelet treatment and 6 and 24 h after endotoxin administration. MiRNAs were screened using LNA-based qPCR, followed by TaqMan-qPCR validation of candidates. Clinical validation was performed in 41 sepsis patients. Platelet-enriched miR-197, miR-223 and miR-223* were decreased in volunteers following antiplatelet therapy. Endotoxin increased platelet miRNAs, whilst the opposite effect was seen for leukocyte-enriched miR-150. Neither of these endotoxin-mediated effects were altered by P2Y 12 inhibitors. Sepsis patients with fatal outcomes ( n = 12) had reduced miR-150 levels compared with survivors ( n = 29). In conclusion, we show that miR-150 is downregulated in experimental endotoxemia and can predict survival in sepsis but is unaffected by P2Y 12 inhibition. While P2Y 12 inhibition reduces platelet-associated miRNAs in healthy volunteers, it fails to attenuate the response of platelet miRNAs to endotoxemia.

Background: Arterial stiffening is central in the vascular aging process. Traditionally, vascular research has focused on atherosclerotic vascular disease, whereas arterial stiffness has not attracted similar attention., Objectives: The purpose of this study was to assess lifetime trajectories of arterial stiffening in Chinese populations facing a high burden of cardiovascular disease, with a particular focus on age-sex interactions and potential determinants., Methods: This large-scale observational study comprised 2 independent cross-sectional population samples and 1 prospective cohort totaling 80,415 healthy subjects with brachial-ankle pulse wave velocity (baPWV) measurements available. Associations with potential risk conditions were analyzed using linear regression, linear random intercepts mixed models, and L1-regularized linear models., Results: The dynamics of age-dependent arterial stiffening differed in sexes, with stiffer vessel observed in men from adolescence to age 58 years and in women thereafter. The steeper increase in baPWV in women after menopause is partly explained by the fact that vascular risk factors are more strongly associated with arterial stiffness in women than in men. Age and systolic blood pressures were the strongest determinants of baPWV, whereas other vascular and metabolic risk factors, except low-density lipoprotein cholesterol, showed consistent associations of moderate strength., Conclusions: The significant age-sex interaction in arterial stiffening provides an important clue of explanation for the heightened cardiovascular disease risk in postmenopausal women. Detailed knowledge on lifetime trajectories of arterial stiffening, and its potential risk factors is a prerequisite for the development of new prevention strategies counteracting vascular aging., (Copyright © 2020 American College of Cardiology Foundation.

Background: 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., Methods: 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., Discussion: 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., Trial Registration: EVA-Tyrol has been retrospectively registered at clinicaltrials.gov under NCT03929692 since April 29, 2019.
