RESUMEN
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.

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.

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.

BACKGROUND AND AIMS: Preterm birth has been linked with an increased risk of cardiovascular (CV) disease from childhood into adolescence and early adulthood. In this study, we aimed to investigate differences in CV health profiles between former term- and preterm-born infants in a cohort of Tyrolean adolescents. METHODS: The Early Vascular Aging (EVA)-Tyrol study is a population-based non-randomized controlled trial, which prospectively enrolled 14- to 19-year-old adolescents in North Tyrol, Austria and South Tyrol, Italy between 2015 and 2018. Metrics of CV health (body mass index (BMI), systolic (SBP) and diastolic blood pressure (DBP), smoking, physical activity, dietary patterns, total cholesterol and fasting blood glucose) were assessed and compared between former term- and preterm-born girls and boys. RESULTS: In total, 1,491 study participants (59.5% female, mean age 16.5 years) were included in the present analysis. SBP and DBP were significantly higher in former preterm-born adolescents (mean gestational age 34.6 ± 2.4 weeks) compared to term-born controls (p < 0.01). In the multivariate regression analysis these findings remained significant after adjustment for potential confounders in all models. No differences were found in all other CV health metrics. The number of participants meeting criteria for all seven health metrics to be in an ideal range was generally very low with 1.5% in former term born vs. 0.9% in former preterm born adolescents (p = 0.583). CONCLUSIONS: Preterm birth is associated with elevated SBP and DBP in adolescence, which was even confirmed for former late preterm-born adolescents in our cohort. Our findings underscore the importance of promoting healthy lifestyles in former term- as well as preterm-born adolescents. In addition, we advise early screening for hypertension and long-term follow-up in the group of preterm-born individuals.

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).

BACKGROUND: Intravenous thrombolysis improves functional outcome in patients with acute stroke and frequencies of r-tPA (recombinant tissue-type plasminogen activator) treatment have been increasing over time. We aimed to assess whether functional outcome in r-tPA-treated patients improved over time and to investigate the influence of clinical variables on functional outcome. METHODS: We analyzed data of r-tPA-treated patients in the Austrian Stroke Unit Registry from 2006 to 2019. Favorable functional outcome was defined as modified Rankin Scale score of 0 to 2. Frequencies of modified Rankin Scale score of 0 to 2 were assessed for the overall population and in prespecified subgroups; multivariable logistic regression analysis was performed to assess associations of baseline characteristics including clinically relevant interactions, and outcome. RESULTS: Overall, 4865 out of 9409 r-tPA-treated patients (51.7%) achieved favorable functional outcome 3 months post stroke. Between 2006 and 2019, frequencies of favorable functional outcome increased from 45.9% to 56.8%. In multivariable logistic regression analysis, year of treatment (adjusted odds ratio [adjOR], 1.08 [95% CI, 1.01-1.15]) was associated with favorable functional outcome. Stroke severity (National Institutes of Health Stroke Scale, adjOR, 0.86 [95% CI, 0.85-0.87]), age (61-70 years: adjOR, 0.67 [95% CI, 0.55-0.80], 71-80 years: adjOR, 0.42 [95% CI, 0.35-0.50], >80 years: adjOR, 0.16 [95% CI, 0.13-0.20]), female sex (adjOR, 0.89 [95% CI, 0.79-0.99]), and various comorbidities (eg, atrial fibrillation, prior stroke, diabetes) were negatively associated. Inclusion of interaction terms into the multivariable logistic regression model suggests a positive effect of year of treatment and endovascular treatment by increasing stroke severity on functional outcome (interaction between year of treatment and National Institutes of Health Stroke Scale: adjOR, 1.01 [95% CI, 1.00-1.02], interaction between National Institutes of Health Stroke Scale and endovascular treatment: adjOR, 1.02 [95% CI, 1.01-1.03]). CONCLUSIONS: Frequencies of favorable functional outcome in r-tPA-treated patients have been increasing over time, likely driven by improved outcome in patients with more severe strokes receiving endovascular treatment. However, some subgroups are still less likely to achieve functional independency and deserve particular attention.

Even though cervical artery dissection is one of the main reasons for ischemic stroke in young patients, acute management and post-acute primary or secondary prevention of cerebral ischemia differ significantly in different centers and countries. These discrepancies are reflected by the differences in guideline recommendations of major stroke societies. Our narrative review aims to shed light on the different recommendations in guideline-statements of stroke societies and to give an overview of the current literature concerning acute management and post-acute treatment of cervical artery dissection patients. In general, intravenous thrombolysis and mechanical thrombectomy are recommended, irrespective of stroke etiology, if administered within the label. Secondary prevention of cerebral ischemia can be achieved by antiplatelet intake or anticoagulation, with, to date, neither treatment establishing superiority over the other. Duration of antithrombotic treatment, statin use as well as optimal endovascular approach are still up for debate and need further evaluation. Additionally, it is still unknown, whether the recommendations given in any of the guideline statements are similarly relevant in spontaneous and traumatic cervical artery dissection, as none of the stroke societies differentiates between the two.

OBJECTIVE: Assessment of the prevalence of primary headache disorders, associated risk factors and use of acute/preventive medication in a representative large sample of adolescents. METHODS: Within the EVA-Tyrol project, a community-based non-randomized controlled cross-sectional study, data was collected from adolescents aged 14-19 years from 45 sites across North-, East- and South Tyrol. Headaches were classified according to the latest ICHD-3 and assessed by headache specialists in face-to-face interviews. FINDINGS: Of 1923 participants 930 (48.4%) reported having headaches. Female to male ratio was 2:1. Migraine, tension-type headache and other headache were diagnosed in 10%, 30.2% and 8.2% respectively. Medication overuse was diagnosed in 3.4%, increasing up to 21.7% in participants with chronic headache. The use of preventative medication was not reported by any adolescent. Sleep disturbances (p < 0.05), alcohol consumption (p < 0.05), low physical activity (p < 0.01) and high screen time exposure (p < 0.01) were associated with an increased risk of headaches. CONCLUSION: We report high prevalence of primary headache disorders and medication overuse in a large community-based sample of teenagers. Acute and preventive non-drug and pharmacological treatments are not established due to lack of paediatric headache outpatient clinics. Promoting health education in teenagers and encouraging public awareness, including that of health care providers is pivotal.Trial registration: EVA-Tyrol has been retrospectively registered at clinicaltrials.gov under https://clinicaltrials.gov/ct2/show/NCT03929692 since April 29, 2019.

OBJECTIVE: Head/neck pain is one of the primary symptoms associated with spontaneous cervical artery dissection. Still, data on pain quality, intensity, and long-term dynamics are scarce. METHODS: Spontaneous cervical artery dissection subjects were included if mural hematoma was visualised through T1 fat-saturated MRI at baseline. All available medical records were evaluated and patients were invited to standardised clinical follow-up visits at least 1 year after the index event. RESULTS: In total, 279 subjects were included in the ReSect-study with head/neck pain being the most frequent symptom of spontaneous cervical artery dissection (220 of 273, 80.6%). Pain was of pulling nature in 107 of 218 (49.1%), and extended to the neck area in 145 of 218 (66.5%). In those with prior headache history, pain was novel in quality in 75.4% (42 of 55). Median patient-reported pain intensity was 5 out of 10 with thunderclap-type headache being uncommon (12 of 218, 5.5%). Prior to hospital admission, head/neck pain rarely responded to self-medication (32 of 218, 14.7%). Characteristics did not differ between subjects with and without cerebral ischemia. Pain resolved completely in all subjects within a median of 13.5 days (IQR 12). Upon follow-up in 42 of 164 (25.6%) novel recurring headache occurred, heterogeneous in quality, localisation and intensity. CONCLUSION: We present an in-depth analysis of spontaneous cervical artery dissection-related head/neck pain characteristics and its long-term dynamics.

BACKGROUND: In recent years, there has been increasing evidence that asthma is associated with atherosclerosis and cardiovascular disease. However, data in children and adolescents are scarce and conflicting. We aimed to assess the impact of asthma with and without an allergic component on the carotid intima-media thickness in a large pediatric population. METHODS: The community-based early vascular ageing-Tyrol cohort study was performed between May 2015 and July 2018 in North, East (Austria) and South Tyrol (Italy) and recruited youngster aged 14 years and above. Medical examinations included anthropometric measurements, fasting blood analysis, measurement of the carotid intima-media thickness by high-resolution ultrasound, and a physician guided interview. RESULTS: The mean age of the 1506 participants was 17.8 years (standard deviation 0.90). 851 (56.5%) participants were female. 22 subjects had a physician diagnosis of non-allergic asthma, 268 had inhalative allergies confirmed by a positive radio-allergo-sorbent-test and/or prick test, and 58 had allergic asthma. Compared to healthy controls, participants with non-allergic asthma (411.7 vs. 411.7 µm; p = 0.932) or inhalative allergy (420.0 vs. 411.7 µm; p = 0.118) did not have significantly higher carotid intima-media thickness (cIMT). However, participants with allergic asthma had significantly higher cIMT (430.8 vs. 411.7; p = 0.004) compared to those without and this association remained significant after multivariable adjustment for established cardiovascular risk factors. CONCLUSION: Allergic asthma in the youth is associated with an increased carotid intima-media thickness. Physicians should therefore be aware of allergic asthma as a potential cardiovascular risk factor in children and adolescents. Trial Registration Number The EVA-Tyrol Study has been retrospectively registered at clinicaltrials.gov under NCT03929692 since April 29, 2019.

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. Trial registration clinicaltrials.gov: NCT04205006 on 19 December 2019.

OBJECTIVES: The recommendations of international guidelines for the management of asymptomatic carotid stenosis (ACS) often vary considerably and extend from a conservative approach with risk factor modification and best medical treatment (BMT) alone, to a more aggressive approach with a carotid intervention plus BMT. The aim of the current multispecialty position statement is to reconcile the conflicting views on the topic. MATERIALS AND METHODS: A literature review was performed with a focus on data from recent studies. RESULTS: Several clinical and imaging high-risk features have been identified that are associated with an increased long-term ipsilateral ischemic stroke risk in patients with ACS. Such high-risk clinical/imaging features include intraplaque hemorrhage, impaired cerebrovascular reserve, carotid plaque echolucency/ulceration/ neovascularization, a lipid-rich necrotic core, a thin or ruptured fibrous cap, silent brain infarction, a contralateral transient ischemic attack/stroke episode, male patients < 75 years and microembolic signals on transcranial Doppler. There is growing evidence that 80-99% ACS indicate a higher stroke risk than 50-79% stenoses. CONCLUSIONS: Although aggressive risk factor control and BMT should be implemented in all ACS patients, several high-risk features that may increase the risk of a future cerebrovascular event are now documented. Consequently, some guidelines recommend a prophylactic carotid intervention in high-risk patients to prevent future cerebrovascular events. Until the results of the much-anticipated randomized controlled trials emerge, the jury is still out regarding the optimal management of ACS patients.

Background: Recent advances in acute stroke therapy have been shown to improve clinical outcome and therefore reduce long-term disability. Acute therapy procedures in stroke have a limited time frame after onset of symptoms; thus, rapid emergency management is critical. The Tyrolean Stroke Pathway was developed to optimize the entire treatment pathway from stroke onset to outpatient rehabilitation. Objectives: The description of the Tyrolean Stroke Pathway as an example to optimize the entire treatment pathway of stroke patients in a central European alpine region with a focus on prehospital management. Materials and methods: In four subprojects from the prehospital phase up to outpatient rehabilitation, the project optimized intersections between different phases of care and evaluated the care processes using quality assurance measures. Results: After implementation, thrombolysis rates doubled and functional outcome of stroke patients after 3 months improved and complications, e.g., pneumonia, declined. Access to rehabilitation improved, particularly because of the establishment of quality assured and funded outpatient rehabilitation. Conclusions: The project showed that a holistic standardized stroke pathway from acute management up to outpatient rehabilitation can be successfully implemented in clinical routine. The project improved the entire health care pathway of stroke patients. The Stroke Action Plan for Europe 2018-2030 recommends to have national plans for stroke that encompass the entire chain of care.
RESUMEN
OBJECTIVE: Carotid endarterectomy (CEA) is a preventive procedure aimed at decreasing the subsequent risk of fatal or disabling stroke in patients with significant carotid stenosis. It is well-known that carotid surgery under ultrasound-guided regional anesthesia (US-RA) causes a significant increase in blood pressure, heart rate and stress hormone levels owing to increased sympathetic activity. However, little is known about the effects on cardiac output (CO), cardiac index (CI), and cerebral blood flow (CBF) under US-RA as compared with general anesthesia (GA). METHODS: Patients scheduled for CEA were randomized prospectively to receive US-RA (n = 37) or GA (n = 41). The primary end point was the change in CI after induction of anesthesia and the change from baseline over time at four different times during the entire procedure in the respective randomized US-RA and GA groups. In addition to systolic blood pressure and heart rate, we also recorded peak systolic velocity, end-diastolic velocity, and minimum diastolic velocity as seen from transcranial Doppler ultrasound examination, as well as regional cerebral oxygenation (rSO2) as seen from near-infrared refracted spectroscopy to evaluate cerebral blood flow. RESULTS: In the US-RA group, the CI increased after induction of anesthesia (3.7 ± 0.8 L/min/m2) and remained constant until the end of the procedure. In the GA group CI was significantly lower (2.4 ± 0.6 L/min/m2; P < .001). After induction of anesthesia, the rSO2 remained constant in the GA group on both the ipsilateral (63 ± 9 rSO2) and the contralateral (65 ± 7 rSO2) sides; in contrast, it significantly increased in the US-RA group (ipsilateral 72 ± 8 rSO2; P < .001; contralateral 72 ± 6 rSO2; P < .001). The transcranial Doppler ultrasound parameters (peak systolic velocity, end-diastolic velocity, and minimum diastolic velocity) did not differ between the US-RA and the GA group. The clinical outcome was similarly favorable for both groups. CONCLUSIONS: CI was maintained near baseline values throughout the procedure during US-RA, whereas a significant decrease in CI values was observed during CEA under GA. Near-infrared refracted spectroscopy values, reflecting blood flow in small vessels, were higher in US-RA patients than in those with GA. These differences did not influence clinical outcome.

Dual-energy computed tomography (DECT) allows distinguishing between tissues with similar X-ray attenuation but different atomic numbers. Recent studies demonstrated that this technique has several areas of application in patients with ischemic stroke and a potential impact on patient management. After endovascular stroke therapy (EST), hyperdense areas can represent either hemorrhage or contrast staining due to blood-brain barrier disruption, which can be differentiated reliably by DECT. Further applications are improved visualization of early infarctions, compared to single-energy computed tomography, and prediction of transformation into infarction or hemorrhage in contrast-enhancing areas. In addition, DECT allows detection and evaluation of the material composition of intra-arterial clots after EST. This review summarizes the clinical state-of-the-art of DECT in patients with stroke, and features some prospects for future developments. KEY POINTS: ⢠Dual-energy computed tomography (DECT) allows differentiation between tissues with similar X-ray attenuation but differentatomic numbers. ⢠DECT has several areas of application in patients with ischemic stroke and a potential impact on patient management. ⢠Prospects for future developments in DECT may improve treatment decision-making.

BACKGROUND AND PURPOSE: The polypill approach has been proposed to reduce patients' pill burden, increase medication adherence and lower stroke incidence. However, little is known about patients' attitudes towards polypills for cerebrovascular medication. METHODS: Based on the European Organization for Research and Treatment of Cancer Quality of Life Group questionnaire development guidelines, a questionnaire to measure patients' attitudes towards polypills for the secondary prevention of stroke (phase I-III) was developed. In phase I, issues were generated via literature review and interviews with patients and healthcare professionals. The issues were operationalized into items in phase II. In phase III the questionnaire was validated in a large single-centre sample, and test-retest and internal validity were evaluated. RESULTS: In phase I, 34 relevant issues were identified through literature search and interviews. Pre-testing the questionnaire indicated high applicability and comprehensibility. The final Attitudes towards Polypills Questionnaire was tested in N = 260 patients and showed a two-factor structure. The factors were labelled 'concerns' and 'benefits'. The scales showed acceptable and good internal validity (concerns, Cronbach's α = 0.85; benefits, α = 0.93), but the scales' test-retest validity was ambiguous. On a 0 to 3 rating scale, concerns were rated lower than benefits (mean 1.07, SD 0.69 vs. mean 1.87, SD 0.89). CONCLUSIONS: The Attitudes towards Polypills Questionnaire showed high comprehensibility and content validity to assess German language patients' attitudes towards a polypill medication. Our data and questionnaire may aid the implementation of polypill treatments in clinical practice and can be used in the design of future clinical trials on polypill therapy. Further validation of the questionnaire is advised.

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.

Objectives: Prediction of large vessel occlusion (LVO) is highly relevant for accurate prehospital transportation triage. The Austrian Prehospital Stroke Scale (APSS) score for LVO prediction was developed using critical synthesis of previously published LVO-scores. The aim of this study was to investigate the accuracy of the APSS and compare it to other LVO-scores. Methods: APSS consists of 5 items: "facial palsy," "motor arm," "language," "motor leg" and "gaze deviation." The score ranges from 0 to 9 points. Data from 741 consecutive stroke patients with acute vessel imaging admitted to an independent comprehensive stroke center was used to test the predictive performance of the APSS in context of other LVO-scores (CPSS, FAST-ED, G-FAST, sNIHSS-EMS and RACE). Results: In the prediction of treatable LVO the APSS showed the highest area under the curve (0.834) with significant difference to CPSS (p = 0.010) and G-FAST (p = 0.006) and showed highest sensitivity (69%) as compared to other LVO scores. Specificity (85%), positive predictive value (75%), negative predictive value (81%) and accuracy (79%) were comparable to other LVO scores. Receiver operating curve analysis revealed an optimal cutoff for LVO prediction at APSS equal to 4 points. Conclusions: The easy assessable 5-item APSS score tended to outperform other LVO scores. Real-life prospective evaluation in prehospital setting is ongoing.

Background and Purpose- Frequencies of treatment with r-tPA (recombinant tissue-type plasminogen activator) are increasing over the past 15 years. However, published data on the influence of various demographic and clinical factors on r-tPA treatment as well as estimates of future trajectories are limited. We evaluated time trends and future trajectories of r-tPA treatment in patients with acute stroke and the influence of various factors on r-tPA treatment by analyzing data of 103 970 patients enrolled in the Austrian Stroke Unit Registry from 2006 to 2018, of which 18 953 were treated with r-tPA. Methods- Time trends of r-tPA-treatment were investigated in predefined subgroups (minor/major stroke, age, anterior/posterior circulation stroke); limited exponential time series models were calculated to estimate future trends of r-tPA-treatment. Logistic regression models were calculated to estimate the influence of clinical variables on r-tPA-treatment. Results- Overall, r-tPA treatment frequencies increased from 9.9% in 2006 to 21.8% in 2018. We observed a particular increase in patients >80 years, patients presenting with a National Institutes of Health Stroke Scale Score of 2 to 3, patients with posterior circulation stroke, patients with wake-up stroke, and patients without atrial fibrillation. Forecast of overall r-tPA frequencies predicted a further but flattened increase up to 24% by 2025. Logistic regression of time-dependent associations of clinical variables with r-tPA-treatment revealed increasing odds of r-tPA-treatment in patients with a posterior circulation stroke and decreasing odds of r-tPA-treatment in patients with atrial fibrillation. Conclusions- We observed a positive development of r-tPA-treatment frequencies mirroring increasing confidence with intravenous thrombolysis in clinical practice; however, decreasing odds of r-tPA-treatment over time in patients with atrial fibrillation deserve particular attention.

OBJECTIVE: To assess the time point during infancy and early childhood at which greater than expected weight gain is associated with overweight in adolescence. STUDY DESIGN: Current height, weight, and body mass index (BMI) were assessed in 1520 adolescents (mean age of boys, 15.52 ± 0.84 years; mean age of girls, 15.37 ± 0.77 years). Information on weight and height trajectories during infancy and early childhood (birth and 6 other time points) was extracted from mother-child booklets. Conditional relative weights were computed to estimate greater or lower than expected weight gain (ie, soft tissue gain at a specific age independent of linear growth), and their association with BMI in adolescence was investigated using linear regression analysis. RESULTS: The mean BMI in adolescence was 21.77 ± 3.69 in boys and 21.70 ± 3.50 in girls. The proportion of overweight was 14.8% in each group. Overweight adolescents had significantly higher weight z-scores at birth, 1.2 month, 3.3 months, 7.6 months, 1 year, 2 years, and 4 years of age as compared with normal-weight adolescents. There were significant positive associations of weight z-scores and conditional relative weights with adolescent BMI at all ages except birth, which were strongest after the first year of life. In a majority of overweight adolescents, overweight had manifested within the first 4 years of life. CONCLUSIONS: Greater than expected weigh gain at any time in the first years of life is associated with an increased BMI in adolescence. The effect is strongest after the first year.
