RESUMO

BACKGROUND AND PURPOSE: The effects of the coronavirus disease 2019 (COVID-19) pandemic on telemedical care have not been described on a national level. Thus, we investigated the medical stroke treatment situation before, during, and after the first lockdown in Germany. METHODS: In this nationwide, multicenter study, data from 14 telemedical networks including 31 network centers and 155 spoke hospitals covering large parts of Germany were analyzed regarding patients' characteristics, stroke type/severity, and acute stroke treatment. A survey focusing on potential shortcomings of in-hospital and (telemedical) stroke care during the pandemic was conducted. RESULTS: Between January 2018 and June 2020, 67,033 telemedical consultations and 38,895 telemedical stroke consultations were conducted. A significant decline of telemedical (p < 0.001) and telemedical stroke consultations (p < 0.001) during the lockdown in March/April 2020 and a reciprocal increase after relaxation of COVID-19 measures in May/June 2020 were observed. Compared to 2018-2019, neither stroke patients' age (p = 0.38), gender (p = 0.44), nor severity of ischemic stroke (p = 0.32) differed in March/April 2020. Whereas the proportion of ischemic stroke patients for whom endovascular treatment (14.3% vs. 14.6%; p = 0.85) was recommended remained stable, there was a nonsignificant trend toward a lower proportion of recommendation of intravenous thrombolysis during the lockdown (19.0% vs. 22.1%; p = 0.052). Despite the majority of participating network centers treating patients with COVID-19, there were no relevant shortcomings reported regarding in-hospital stroke treatment or telemedical stroke care. CONCLUSIONS: Telemedical stroke care in Germany was able to provide full service despite the COVID-19 pandemic, but telemedical consultations declined abruptly during the lockdown period and normalized after relaxation of COVID-19 measures in Germany.

RESUMO

BACKGROUND: Chest pain units (CPUs) and stroke units (SUs) provide specialized multidisciplinary in-hospital management for acute chest pain and ischemic stroke. We analyzed exemplary equivalent quality benchmarks in both concepts. MATERIAL AND METHODS: Data from the German CPU registry (2012-2015; 45 certified CPUs, 5881 patients) were compared with data from the SU registry of Rhineland-Palatinate (2011-2015; 29 SUs; 40,380 patients). Parameters comprised demographics, symptoms, diagnosis, medication, critical time intervals, therapeutics, and in-unit outcome. RESULTS: Non-ST-segment elevation myocardial infarction (47.4%) and ischemic stroke (63.0%) were the most frequent entities. An electrocardiogram was performed on average within 7 min in CPUs, cranial imaging within 49 min in SUs. The mean time interval from admission until coronary intervention or lysis was 42 min or 57 min, respectively. Rates of antiplatelet therapy (90.1% vs. 96.0%), brain imaging, and coronary angiography were high (99.3% vs. 81.1%) and the mortality was low (0.8% for CPUs vs. 3.6% for SUs). The length of stay was shorter in CPUs (1.5 days vs. 4.4 days). CONCLUSION: As reimbursement for emergency medicine in Germany was recently rearranged, quality benchmarking has gained incremental importance. Mandatory joint quality measurement in both concepts ensuring gap analysis and process improvement is encouraged.

RESUMO

BACKGROUND: Chest pain units (CPU) and stroke units (SU) have both become established as essential components of clinical emergency care. For both instances dedicated certification processes are installed. Up to summer 2020, 290 CPUs and 335 SUs have been successfully certified. OBJECTIVE: The aim of this review is to compare the structures and the current certification situation of CPUs and SUs. Also, the younger CPU certification process is compared to the long established SU certification standard. MATERIAL UND METHODS: The comparison includes the historical background, the certification process, quality benchmarking, possible additive structures, the current status of certification in Germany, the transfer of the concept to the European level as well as reimbursement issues. RESULTS: Both certification concepts show clear analogies. Evidence for SUs is supported by a positive Cochrane analysis and for CPUs there are many studies from the German CPU registry. The main differences include a uniform CPU system versus a multistep SU system of certification. Furthermore, SU have obligatory elements of quality documentation but only facultative quality indicator assessment for CPUs. From an economic viewpoint operation and procedural key (OPS) numbers guarantee a better reflection of the use of resources in the complex treatment of stroke, which could not yet be established for CPUs. CONCLUSION: The well-established CPU concept could additionally benefit from a superordinate quality control. Adequate quality benchmarking appears to be fundamental for gap analyses and for the establishment of a separate remuneration structure. In this respect the German Society for Cardiology as the certifying institution is required to establish an appropriate mechanism within the framework of regular updates of criteria.

RESUMO

OBJECTIVE: A multigenetic pro-inflammatory profile may increase stroke risk. We investigated whether a higher number of pro-inflammatory genetic variants are associated with ischaemic stroke risk and whether other risk factors further elevate this risk. METHODS: In a case-control study with 470 ischaemic stroke patients (cases) and 807 population controls, we investigated 23 haplotypes or alleles in 16 inflammatory genes (interleukin [IL]1A, IL1B, IL1 receptor antagonist, IL6, IL6 receptor, IL10, tumour necrosis factor-a; C-C motif chemokine ligand 2, C-C motif chemokine receptor 5, C-reactive protein (CRP), intercellular adhesion molecule 1, transforming growth factor ß1, E-Selectin, selenoprotein S, cluster determinant 14, histone deacetylase 9 [HDAC9]). We constructed an extended gene score (EGS) as the sum of all individual risk alleles and analysed its effect on stroke, just as its association and interaction with cardiovascular risk factors and infectious scores (IgG antibodies against 5 respectively IgA antibodies against 4 microbial antigens). RESULTS: Cases were less likely to carry the minor allele of IL10 rs1800872 and more likely to carry the HDAC9 allele rs11984041 and the pro-inflammatory haplotype of CRP, although the latter was not statistically significant in our study. Overall, cases tended to have more pro-inflammatory alleles and haplotypes than controls (mean ± SD 13.25 ± 2.25 and 13.04 ± 2.41, respectively). However, the EGS only slightly and not significantly increased the risk of stroke (OR 1.04, 95% CI 0.99-1.09). Its effect was neither associated with included risk factors nor with IgA and IgG infectious scores, and we found no significant interaction effects. CONCLUSION: A more pro-inflammatory genetic profile might increase stroke risk to some extent. This potential effect is most likely independent of established cardiovascular risk factors and the infectious burden of an individual.

RESUMO

Background and Purpose- We sought to explore the effect of genetic imbalance on functional outcome after ischemic stroke (IS). Methods- Copy number variation was identified in high-density single-nucleotide polymorphism microarray data of IS patients from the CADISP (Cervical Artery Dissection and Ischemic Stroke Patients) and SiGN (Stroke Genetics Network)/GISCOME (Genetics of Ischaemic Stroke Functional Outcome) networks. Genetic imbalance, defined as total number of protein-coding genes affected by copy number variations in an individual, was compared between patients with favorable (modified Rankin Scale score of 0-2) and unfavorable (modified Rankin Scale score of ≥3) outcome after 3 months. Subgroup analyses were confined to patients with imbalance affecting ohnologs-a class of dose-sensitive genes, or to those with imbalance not affecting ohnologs. The association of imbalance with outcome was analyzed by logistic regression analysis, adjusted for age, sex, stroke subtype, stroke severity, and ancestry. Results- The study sample comprised 816 CADISP patients (age 44.2±10.3 years) and 2498 SiGN/GISCOME patients (age 67.7±14.2 years). Outcome was unfavorable in 122 CADISP and 889 SiGN/GISCOME patients. Multivariate logistic regression analysis revealed that increased genetic imbalance was associated with less favorable outcome in both samples (CADISP: P=0.0007; odds ratio=0.89; 95% CI, 0.82-0.95 and SiGN/GISCOME: P=0.0036; odds ratio=0.94; 95% CI, 0.91-0.98). The association was independent of age, sex, stroke severity on admission, stroke subtype, and ancestry. On subgroup analysis, imbalance affecting ohnologs was associated with outcome (CADISP: odds ratio=0.88; 95% CI, 0.80-0.95 and SiGN/GISCOME: odds ratio=0.93; 95% CI, 0.89-0.98) whereas imbalance without ohnologs lacked such an association. Conclusions- Increased genetic imbalance was associated with poorer functional outcome after IS in both study populations. Subgroup analysis revealed that this association was driven by presence of ohnologs in the respective copy number variations, suggesting a causal role of the deleterious effects of genetic imbalance.

RESUMO

BACKGROUND: Physical activity (PA) is associated with lower risk of stroke. We tested the hypothesis that lack of pre-stroke PA is an independent predictor of poor outcome after first-ever ischemic stroke. METHODS: We assessed recent self-reported PA and other potential predictors for loss of functional independence - modified Rankin Scale (mRS) > 2 - one year after first-ever ischemic stroke in 1370 patients registered between 2006 and 2010 in the Ludwigshafen Stroke Study, a population-based stroke registry. RESULTS: After 1 year, 717 (52.3%) of patients lost their independence including 251 patients (18.3%) who had died. In multivariate logistic regression analysis lack of regular PA prior to stroke (Odds Ratio (OR) 1.7, Confidence Interval (CI) 1.1-2.5), independently predicted poor outcome together with higher age (65-74: OR 1.7; CI 1.1-2.8, 75-84 years: OR 3.3; CI 2.1-5.3; ≥85 years OR 14.5; CI 7.4-28.5), female sex (OR 1.5; CI 1.1-2.1), diabetes mellitus (OR 1.8; CI 1.3-2.5), stroke severity (OR 1.2; CI 1.1-1.2), probable atherothrombotic stroke etiology (OR 1.8; CI 1.1-2.8) and high leukocyte count (> 9.000/mm3; OR 1.4; CI 1.0-1.9) at admission. Subclassifying unknown stroke etiology, embolic stroke of unknown source (ESUS; n = 40, OR 2.2; CI 0.9-5.5) tended to be associated with loss of independence. CONCLUSION: In addition to previously reported factors, lack of PA prior to stroke as potential indicator of worse physical condition, high leukocyte count at admission as indicator of the inflammatory response and probable atherothrombotic stroke etiology might be independent predictors for non-functional independence in first-ever ischemic stroke.

RESUMO

BACKGROUND: The risk of stroke after cardiac and carotid surgery is well established. In contrast, stroke risk in association with non-cardiac and non-carotid surgery and its time course are insufficiently known. We investigated the prevalence of recent and planned surgery among patients with stroke and transient ischemic attack (TIA), time dependency of stroke risk, stroke etiology, and interruption of antithrombotic medication in association with surgery. METHODS: Data on type and date of surgery and similar interventions within the last year or planned for the next 2 weeks were anonymously collected together with demographic data, vascular risk factors, stroke severity, handicap before stroke and stroke etiology within a state-wide, mandatory, hospital-based acute stroke care quality monitoring project (Rhineland-Palatinate, Germany) for 1 year (2010). RESULTS: Non-carotid and non-cardiothoracic surgery was reported as performed within 1 year before the index event or as planned for the next 2 weeks thereafter in 532 out of 12,120 patients with ischemic stroke/TIA (4.4%). Compared to 91-365 days before stroke/TIA as reference period, risk of cerebral ischemia (per day analysis) was increased for surgery within 61-90 days before ischemia (rate ratio 2.0, 95% CI 1.5-2.8) and continuously increased along shorter intervals between stroke and surgery (31-60 days: rate ratio 3.6, 95% CI 2.9-4.5; 15-30 days: rate ratio 8.2, 95% CI 6.7-10.1; 8-14 days: rate ratio 13.2, 95% CI 10.3-16.8; 4-7 days: rate ratio 16.5, 95% CI 12.2-22.1) peaking at an interval of 1-3 days before ischemia (rate ratio 34.0, 95% CI 26.9-42.8). On the day of surgery, rate ratio was 14.8 (95% CI 7.8-27.9) and for planned surgery it was 2.7 (95% CI 1.8-4.0). Results were similar for first-ever and for recurrent ischemic stroke. Perioperative stroke/TIA was positively associated with atrial fibrillation and cardioembolic stroke etiology, higher mortality, more severe neurological deficits at discharge, and longer hospital stay; and it was inversely associated with microangiopathic etiology and discharge at home. In 34.5% of patients with recent/planned surgery, prior antithrombotic or anticoagulant medication had been interrupted. CONCLUSIONS: Recent or planned surgery imposes a considerable short-term stroke risk particularly by cardioembolism with cessation of medication as an important contributor. Stroke after surgery is associated with poor outcome and high mortality. Better strategies to reduce the burden of perioperative stroke are urgently required.

RESUMO

BACKGROUND: Genetic and environmental risk factors are assumed to contribute to the susceptibility to cervical artery dissection (CeAD). To explore the role of genetic imbalance in the etiology of CeAD, copy number variants (CNVs) were identified in high-density microarrays samples from the multicenter CADISP (Cervical Artery Dissection and Ischemic Stroke Patients) study and from control subjects from the CADISP study and the German PopGen biobank. Microarray data from 833 CeAD patients and 2040 control subjects (565 subjects with ischemic stroke due to causes different from CeAD and 1475 disease-free individuals) were analyzed. Rare genic CNVs were equally frequent in CeAD-patients (16.4%; n=137) and in control subjects (17.0%; n=346) but differed with respect to their genetic content. Compared to control subjects, CNVs from CeAD patients were enriched for genes associated with muscle organ development and cell differentiation, which suggests a possible association with arterial development. CNVs affecting cardiovascular system development were more common in CeAD patients than in control subjects (p=0.003; odds ratio (OR) =2.5; 95% confidence interval (95% CI) =1.4-4.5) and more common in patients with a familial history of CeAD than in those with sporadic CeAD (p=0.036; OR=11.2; 95% CI=1.2-107). CONCLUSION: The findings suggest that rare genetic imbalance affecting cardiovascular system development may contribute to the risk of CeAD. Validation of these findings in independent study populations is warranted.

RESUMO

BACKGROUND AND PURPOSE: The association between socioeconomic status in adulthood and the risk of stroke is well established; however, the independent effects of socioeconomic conditions in different life phases are less understood. METHODS: Within a population-based stroke registry, we performed a case-control study with 470 ischemic stroke patients (cases) aged 18 to 80 years and 809 age- and sex-matched stroke-free controls, randomly selected from the population (study period October 2007 to April 2012). We assessed socioeconomic conditions in childhood, adolescence, and adulthood, and developed a socioeconomic risk score for each life period. RESULTS: Socioeconomic conditions were less favorable in cases regarding paternal profession, living conditions and estimated family income in childhood, school degree, and vocational training in adolescence, last profession, marital status and periods of unemployment in adulthood. Using tertiles of score values, low socioeconomic conditions during childhood (odds ratio 1.77; 95% confidence interval 1.20-2.60) and adulthood (odds ratio 1.74; 95% confidence interval 1.16-2.60) but not significantly during adolescence (odds ratio 1.64; 95% confidence interval 0.97-2.78) were associated with stroke risk after adjustment for risk factors and other life stages. Medical risk factors attenuated the effect of childhood conditions, and lifestyle factors reduced the effect of socioeconomic conditions in adolescence and adulthood. Unfavorable childhood socioeconomic conditions were particularly associated with large artery atherosclerotic stroke in adulthood (odds ratio 2.13; 95% confidence interval 1.24-3.67). CONCLUSIONS: This study supports the hypothesis that unfavorable childhood socioeconomic conditions are related to ischemic stroke risk, independent of established risk factors and socioeconomic status in adulthood, and fosters the idea that stroke prevention needs to begin early in life.

RESUMO

BACKGROUND: The possibility to survive with amyotrophic lateral sclerosis (ALS) varies considerably and survival extends from a few months to several years. A number of demographic and clinical factors predicting survival have been described; however, existing data are conflicting. We intended to predict patient survival in a population-based prospective cohort of ALS patients from variables known up to the time of diagnosis. METHODS: Incident ALS patients diagnosed within three consecutive years were enrolled and regularly followed up. Candidate demographic and disease variables were analysed for survival probability using the Kaplan-Meier method. The Cox proportional hazard regression model was used to assess the influence of selected predictor variables on survival prognosis. RESULTS: In the cohort of 193 patients (mean age 65.8, standard deviation 10.2 years), worse prognosis was independently predicted by older age, male gender, bulbar onset, probable or definite ALS according to El Escorial criteria, shorter interval between symptom onset and diagnosis, lower Functional Rating Scale, diagnosis of frontotemporal dementia, and living without a partner. CONCLUSIONS: Taking into account these predictor variables, an approximate survival prognosis of individual ALS patients at diagnosis seems feasible.

RESUMO

BACKGROUND AND PURPOSE: A recent surgery may be one of the trigger factors precipitating stroke and transient ischemic attack (TIA). While stroke in cardiac and carotid surgery has been well studied, less is known on stroke risk after surgery outside the heart and brain supplying arteries. We tested the hypothesis that preceding non-neurosurgical, non-cardiothoracic, and non-carotid surgery and other interventions temporarily increase the risk of stroke and transient ischemic attack (TIA) and investigated the risk related to different time periods between interventions and stroke/TIA. METHODS: In the Ludwigshafen Stroke Study, a population-based stroke registry, we assessed surgery and other interventions within the year preceding stroke and TIA. The risk factor profiles of patients with and without prior intervention were compared and rate ratios (RR) were calculated for different time periods with 91-365 days before stroke and TIA serving as reference period. RESULTS: In 2006 and 2007, 803 patients without and 116 patients with non-neurosurgical, non-cardiothoracic, and non-carotid intervention within the preceding year were identified. Elective (n = 21) and posttraumatic orthopedic (n = 14), eye (n = 14), and visceral surgery (n = 11) dominated. Interventions within 0-30 days (n = 34; RR 4.72; 95% confidence interval (CI) 2.70-8.26) but not within 31-60 or 61-90 days before stroke/TIA were observed more often than in the reference period. Interventions were more common within day 8-30 before stroke/TIA (RR 3.26; 95% CI 1.66-6.39), particularly common within the preceding week (RR 9.52; 95% CI 3.77-24.1) and most common in the preceding 2 days (RR 27.1; 95% CI 5.97-123) as compared to the reference period. Atrial fibrillation (AF) but not other risk factors was more common in patients with interventions within 30 days (n = 15; 44.1%) as compared to patients with more antecedent interventions (n = 19; 23.2%, p = 0.022) and those without surgery (n = 222; 27.6%, p = 0.031). Interventions within 30 days before stroke/TIA, were associated with total ischemic stroke (RR 6.11; 95% CI 3.32-11.2), first-ever in a lifetime ischemic stroke (RR 5.62; 95% CI 2.83-11.1) and recurrent ischemic stroke (RR 7.50; 95% CI 2.88-19.6). CONCLUSION: Recent non-cardiothoracic, non-carotid, and non-neurosurgical interventions are associated with an increased risk of stroke lasting for about 1 month and being particularly high within the first days. AF may be among the mechanisms linking interventions and stroke besides induction of a procoagulant state and interruption of medication.

RESUMO

BACKGROUND: Cardioembolic stroke (CES) due to atrial fibrillation (AF) is associated with high stroke mortality. Oral anticoagulation (OAC) reduces stroke mortality, however, the impact of OAC-administration during hospital stay post ischemic stroke on mortality is unclear. We determined whether the timing of OAC initiation among other prognostic factors influenced mortality after CES. METHODS: Within the Ludwigshafen Stroke Study (LuSSt), a prospective population-based stroke register, we analysed all patients with a first ever ischemic stroke or TIA due to AF from 2006 until 2010. We analysed whether treatment or non-treatment with OAC and initiation of OAC-therapy during and after hospitalization influenced stroke mortality within 500 days after stroke/TIA due to AF. RESULTS: In total 479 patients had a first-ever ischemic stroke (n = 394) or TIA (n = 85) due to AF. One-year mortality rate was 28.4%. Overall, 252 patients (52.6%) received OAC. In 181 patients (37.8%), OAC treatment was started in hospital and continued thereafter. Recommendation to start OAC post discharge was given in 110 patients (23.0%) of whom 71 patients received OAC with VKA (14.8%). No OAC-recommendation was given in 158 patients (33.0%). In multivariate Cox regression analysis, higher age (HR 1.04; 95% CI 1.02-1.07), coronary artery disease (HR: 1.6; 95% CI 1.1-2.3), higher mRS-score at discharge (HR 1.24; 95% CI 1.09-1.4), and OAC treatment ((no OAC vs started in hospital (HR: 5.4; 95% CI 2.8-10.5), were independently associated with stroke mortality. OAC-timing did not significantly influence stroke mortality (started post discharge vs. started in hospital (HR 0.3; 95% CI 0.07-1.4)). CONCLUSIONS: OAC non-treatment is the main predictor for stroke mortality. Although OAC initiation during hospital stay showed a trend towards higher mortality, early initiation in selected patients is an option as recommendation to start OAC post hospital was implemented in only 64.5%. This rate might be elevated by implementation of special intervention programs.

RESUMO

BACKGROUND: Survival in amyotrophic lateral sclerosis varies considerably. About one third of the patients die within 12 months after first diagnosis. The early recognition of fast progression is essential for patients and neurologists to weigh up invasive therapeutic interventions. In a prospective, population-based cohort of ALS patients in Rhineland-Palatinate, Germany, we identified significant prognostic factors at time of diagnosis that allow prediction of early death within first 12 months. METHODS: Incident cases, diagnosed between October 2009 and September 2012 were enrolled and followed up at regular intervals of 3 to 6 months. Univariate analysis utilized the Log-Rank Test to identify association between candidate demographic and disease variables and one-year mortality. In a second step we investigated a multiple logistic regression model for the optimal prediction of one-year mortality rate. RESULTS: In the cohort of 176 ALS patients (mean age 66.2 years; follow-up 100%) one-year mortality rate from diagnosis was 34.1%. Multivariate analysis revealed that age over 75 years, interval between symptom onset and diagnosis below 7 months, decline of body weight before diagnosis exceeding 2 BMI units and Functional Rating Score below 31 points were independent factors predicting early death. CONCLUSIONS: Probability of early death within 12 months from diagnosis is predicted by advanced age, short interval between symptom onset and first diagnosis, rapid decline of body weight before diagnosis and advanced functional impairment.

RESUMO

Purpose: This study aimed at comparing clinical outcome, recanalization success and time metrics in the "drip and ship" (DS) vs. "drive the doctor" (DD) concept in a comparable setting. Methods: This is a retrospective analysis of thrombectomy registries of a comprehensive stroke center (CSC) and a thrombectomy-capable stroke center (TSC). Patients, who were transferred from the TSC to the CSC, were classified as DS. Patients treated at the TSC by an interventionalist transferred from the CSC were classified as DD. Good outcome was defined as mRS 0-2 or equivalent to premorbid mRS at discharge. Recanalization (TICI 2b-3 or equivalent) and time metrics were compared in both groups. Results: In total, 295 patients were included, of which 116 (39.3%) were treated in the DS concept and 179 (60.7%) in the DD concept. Good clinical outcome was similarly achieved in DS and DD (DS 25.0% vs. DD 31.3%, P = 0.293). mRS on discharge (DS median 4, DD median 4, P = 0.686), NIHSS improvement (DS median 4, DD median 5, P = 0.582) and NIHSS on discharge (DS median 9, DD median 7, P = 0.231) were similar in both groups. Successful reperfusion was achieved similarly in DS (75.9%) and DD as well (81.0%, P = 0.375). Time from onset to reperfusion (median DS 379 vs. DD 286 min, P = 0.076) and time from initial imaging to reperfusion were longer in DS compared to DD (median DS 246 vs. DD 162 min, P < 0.001). Conclusion: The DD concept is time saving while achieving similar clinical outcome and recanalization results.

RESUMO

BACKGROUND: Patients with ischaemic stroke are at risk of recurrent stroke. In this study, we aimed to compare the effect of a structured ambulatory post-stroke care programme versus usual care on recurrent vascular events and death and control of cardiovascular risk factors. METHODS: We did a prospective, open-label, cluster-randomised controlled trial (SANO) at stroke centres in regions of Germany. A cluster was defined as a region in which acute stroke care is provided by a participating stroke centre. Patients were eligible for participation if they were aged 18 years or older, had no severe disabilities before the index stroke (modified Rankin scale 0-1), had at least one modifiable cardiovascular risk factor, and presented within 14 days of symptom onset of their first ischaemic stroke. The participating regions were randomly assigned (1:1) to the intervention and control group (usual care) by the statistician using block randomisation (block sizes of six), stratified by rural and urban regions. In intervention regions, a cross-sectoral multidisciplinary network was established to provide a 1-year organisational and patient-centred intervention. Due to the type of intervention, masking of participants and study physicians was not possible. Endpoint adjudication was performed by an independent endpoint adjudication committee who were masked to cluster allocation. The primary endpoint was a composite of recurrent stroke, myocardial infarction, and all-cause death within 12 months after baseline assessment, assessed in the modified intention-to-treat (mITT) population, which included all patients who did not withdraw consent and completed the primary endpoint assessment at 12 months. This study was registered with the German Clinical Trials Register, DRKS00015322. FINDINGS: Between Jan 1, 2019 and Dec 22, 2020, 36 clusters were assessed for eligibility, of which 30 were randomly assigned to the intervention group (n=15 clusters) or control group (n=15 clusters). No clusters dropped out of the study. 1203 (86%) of 1396 enrolled patients in the intervention group and 1283 (92%) of 1395 enrolled patients in the control group were included in the mITT population. The primary endpoint was confirmed in 64 (5·3%) of 1203 patients in the intervention group and 80 (6·2%) of 1283 patients in the control group (unadjusted odds ratio [OR] 0·80 [95% CI 0·49-1·30]; adjusted OR [aOR] 0·95 [95% CI 0·54-1·67]). All-cause deaths occurred in 31 (2·4%) of 1203 patients in the intervention group and 12 (1·0%) of 1283 patients in the control group. The incidence of serious adverse events was higher in the intervention group (266 [23·1%] of 1151) than the control group (106 [9·2%] of 1152). Falls (134 [11·4%] of 1203 patients in the intervention group; 39 [3·3%] of 1152 patients in the control group), hypertensive crisis (55 [4·7%]; 34 [2·8%]), and diagnosis of depression (51 [4·3%]; 13 [1·1%]) were the most frequent adverse events in both groups. No differences were identified in the rate of readmission to hospital between groups. INTERPRETATION: No differences were identified between patients with ischaemic stroke in the intervention group and control group with regard to the incidence of vascular events 1 year after baseline assessment, despite positive effects with regard to the control of some cardiovascular risk factors. Longer-term effects and other potentially favourable effects on stroke-related sequelae and quality of life require further evaluation. FUNDING: Innovation Fund of the Federal Joint Committee.

RESUMO

BACKGROUND AND PURPOSE: We compared among young patients with ischemic stroke the distribution of vascular risk factors among sex, age groups, and 3 distinct geographic regions in Europe. METHODS: We included patients with first-ever ischemic stroke aged 15 to 49 years from existing hospital- or population-based prospective or consecutive young stroke registries involving 15 cities in 12 countries. Geographic regions were defined as northern (Finland, Norway), central (Austria, Belgium, France, Germany, Hungary, The Netherlands, Switzerland), and southern (Greece, Italy, Turkey) Europe. Hierarchical regression models were used for comparisons. RESULTS: In the study cohort (n=3944), the 3 most frequent risk factors were current smoking (48.7%), dyslipidemia (45.8%), and hypertension (35.9%). Compared with central (n=1868; median age, 43 years) and northern (n=1330; median age, 44 years) European patients, southern Europeans (n=746; median age, 41 years) were younger. No sex difference emerged between the regions, male:female ratio being 0.7 in those aged <34 years and reaching 1.7 in those aged 45 to 49 years. After accounting for confounders, no risk-factor differences emerged at the region level. Compared with females, males were older and they more frequently had dyslipidemia or coronary heart disease, or were smokers, irrespective of region. In both sexes, prevalence of family history of stroke, dyslipidemia, smoking, hypertension, diabetes mellitus, coronary heart disease, peripheral arterial disease, and atrial fibrillation positively correlated with age across all regions. CONCLUSIONS: Primary preventive strategies for ischemic stroke in young adults-having high rate of modifiable risk factors-should be targeted according to sex and age at continental level.

RESUMO

BACKGROUND: Socioeconomic conditions may strongly influence the risk of stroke. We tested the hypotheses that indexes of social status in different life periods including childhood are inversely associated with stroke risk and that there is a cumulative effect of social conditions during lifetime on the risk of stroke. Furthermore, we investigated whether social advancement compared to the parental generation is associated with reduced stroke risk. METHODS: In a case-control study, we assessed parental professional status, highest school degree, professional education and the last professional activity in 370 consecutive patients with ischemic or hemorrhagic stroke or transient ischemic attack [TIA; age 60.7 ± 12.8 years (mean ± standard deviation); 31.1% women] and 370 age- and sex-matched control subjects randomly selected from the general population of the same area. RESULTS: Higher level of school exams [odds ratio (OR) 0.58, 95% confidence interval (CI) 0.39-0.86], university or polytechnic high school degrees (OR 0.39, 95% CI 0.24-0.63), nonmanual (last or current) professional activity (OR 0.51, 95% CI 0.37-0.71) and father's nonmanual professional activity (OR 0.64, 95% 0.43-0.97) were associated with a lower risk of stroke/TIA. Adjustment for vascular risk factors including current smoking and alcohol consumption reduced the strength of these associations and rendered them nonsignificant except for university or polytechnic high school degrees (OR 0.49, 95% CI 0.27-0.87). Additional adjustment for regular sports activity further attenuated the association between academic degrees and risk of stroke/TIA (OR 0.56, 95% CI 0.31-1.02). A score summarizing 4 lifetime social indexes was not independently associated with stroke risk (OR 0.67, 95% CI 0.39-1.16). Social advancement as assessed by changes from paternal manual work to nonmanual work in the index generation was more common among control subjects (23.5%) than patients (15.3%; p = 0.0097), but such advancement was not independently associated with stroke/TIA after adjustment for all covariables (OR 0.82, 95% CI 0.50-1.33). CONCLUSIONS: Socioeconomic conditions were inversely linked to the risk of stroke/TIA. These associations were strongly influenced by lifestyle factors such as smoking, alcohol consumption and mainly sports activity. Stroke preventive strategies may have a particularly large potential if they focus on such lifestyle habits in socially disadvantaged groups.

RESUMO

BACKGROUND: Regional deprivation can increase the risk of illness and adversely affect care outcomes. In this study, we investigated for the German state of Rhineland-Palatinate whether spatial-structural disadvantages are associated with an increased frequency of ischemic stroke and with less favorable care outcomes. METHODS: We compared billing data from DRG statistics (2008-2017) and quality assurance data (2017) for acute ischemic stroke with the German Index of Multiple Deprivation 2010 (GIMD 2010) for the 36 districts (Landkreise) and independent cities (i.e., cities not belonging to a district) in Rhineland-Palatinate using correlation analyses, a Poisson regression analysis, and logistic regression analyses. RESULTS: The age-standardized stroke rates (ASR) ranged from 122 to 209 per 100 000 inhabitants, while the GIMD 2010 ranged from 4.6 to 47.5; the two values were positively correlated (Spearman's ρ = 0.47; 95% confidence interval [0.16; 0.85]). In 2017, mechanical thrombectomies were performed more commonly (5.7%) in the first GIMD 2010 quartile of the regional areas (i.e., in the least deprived areas) than in the remaining quartiles (4.2-4.6%). The intravenous thrombolysis rates showed no differences from one GIMD 2010 quartile to another. Severe neurological deficits (National Institutes of Health Stroke Scale ≥ 5) on admission to the hospital were slightly more common in the fourth quartile (i.e., in the most deprived areas), while antiplatelet drugs and statins were somewhat less commonly ordered on discharge in those areas than in the first quartile. CONCLUSION: These findings document a relationship between regional deprivation and the occurrence of acute ischemic stroke. Poorer GIMD 2010 scores were associated with worse care outcomes in a number of variables, but the absolute differences were small.
