Increasing Incidence of Hospitalization for Stroke and Transient Ischemic Attack in Young Adults: A Registry-Based Study

Factors associated with progression of arterial stiffness in ischemic stroke survivors: the Norwegian Stroke in the Young Study

BACKGROUND

Progressive arterial stiffening may increase the risk of recurrent cardiovascular events in ischemic stroke survivors. Information about factors associated with progressive arterial stiffening during the follow-up of young patients with ischemic stroke is lacking.

METHODS

Arterial stiffness by carotid-femoral pulse wave velocity (cf-PWV) and ambulatory 24-hour blood pressure (24hBP) were assessed in 81 women and 190 men ≤60 years of age included in the Norwegian Stroke in the Young (NOR-SYS) study 3 months and 5.5 years after the incident ischemic stroke, representing baseline and follow-up. Covariables of change in cf-PWV were identified using linear regression analysis.

RESULTS

At baseline, women had less prevalent hypertension (53% vs. 69%, p < 0.05), and lower clinic and 24hBP than men, whereas age, obesity, and prevalence of smoking and antihypertensive drug treatment did not differ. During follow-up, systolic 24hBP remained unchanged, while diastolic 24hBP fell significantly (p < 0.01). Cf-PWV was lower in women both at baseline (7.3 m/s vs. 8.1 m/s) and at follow-up (7.3 m/s vs. 8.0 m/s, both p < 0.001), but the average change during follow-up did not differ between genders. In linear regression analysis, an increase in cf-PWV at the 5-year follow-up was associated with the presence of hypertension and lower cf-PWV at baseline, and higher systolic 24hBP and lack of use of antihypertensive treatment at follow-up (all p < 0.05).

CONCLUSION

In ischemic stroke survivors participating in the NOR-SYS study, the 5-year increase in cf-PWV did not differ between genders and was associated with higher systolic 24hBP and lack of antihypertensive treatment.

The combined impact of migraine and gestational diabetes on long-term risk of premature myocardial infarction and stroke: A population-based cohort study

OBJECTIVE

To examine the combined impact of migraine and gestational diabetes mellitus (GDM) on the risks of premature (persons aged ≤60 years) major adverse cardiovascular and cerebrovascular events (MACCE) based on a composite endpoint of fatal and non-fatal myocardial infarction (MI) and stroke.

BACKGROUND

Migraine and GDM are risk factors for cardiovascular disease. It is unknown how the combination of migraine and GDM may affect cardiovascular disease risk.

METHODS

In a Danish population-based cohort longitudinal study, we established four cohorts among women with at least one pregnancy during 1996-2018: women with migraine, women with GDM, women with both migraine and GDM, and women free of migraine and free of GDM. Risks of premature MACCE and component endpoints were assessed for each cohort.

RESULTS

We included 1,307,456 women free of migraine and free of GDM, 56,811 women with migraine, 24,700 women with GDM, and 1484 women with migraine and GDM. The 20-year absolute risk of MACCE was 1.3% (MI: 0.4%, ischemic stroke: 0.6%, hemorrhagic stroke: 0.3%) among women free of migraine and free of GDM, 2.3% (MI: 0.8%, ischemic stroke: 1.2%, hemorrhagic stroke: 0.5%) among women with migraine, 2.2% (MI: 1.0%, ischemic stroke: 1.0%, hemorrhagic stroke: 0.4%) among women with GDM, and 3.7% (MI: 1.7%, ischemic stroke: 1.7%, hemorrhagic stroke: 0.3%) among women with both migraine and GDM. The 20-year adjusted hazard ratio of premature MACCE was 1.65 (95% confidence interval [CI] 1.49-1.82) for women with migraine; 1.64 (95% CI 1.37-1.96) for women with GDM; and 2.35 (95% CI 1.03-5.36) for women with both GDM and migraine when compared with women free of migraine and free of GDM.

CONCLUSIONS

Migraine and GDM were each independently associated with an increased risk of MACCE. Risk of premature MACCE was greatest among women with both migraine and GDM, although this risk estimate was imprecise.

Strength of association of classical vascular risk factors in young patients with ischaemic stroke: a case-control study

INTRODUCTION

Recent studies have reported an increasing incidence of ischaemic stroke among young adults. However, the strength of the association between traditional vascular risk factors has not been fully established.

METHODS

We compared 120 patients with a first ischaemic stroke before the age of 55 years admitted to the stroke unit of our centre with 600 healthy non-stroke controls from a population-based cohort study (HERMEX), matched for sex. Risk factors assessed included: hypertension, obesity, auricular fibrillation, current smoking, estimated glomerular filtration rate (eGFR), total cholesterol, low-density lipoprotein cholesterol (LDL-C), triglycerides, high-density lipoprotein cholesterol (HDL-C) and diabetes mellitus. We used logistic regression analysis and calculated population attributable risk. We performed an overall analysis, by sex and aetiological subgroup.

RESULTS

Using logistic regression analysis, we found that overall, the significant risk factors were: hypertension (OR: 1.58; 95%CI: 1.01-2.50), atrial fibrillation (OR: 4.77; 95%CI: 1.20-19.00), low eGFR (OR: 4.74; 95%CI: 1.3-21.94) and low HDL-C (OR: 5.20; 95%CI: 3.29-8.21), as well as smoking for males (OR: 1.86; 95%CI: 1.14-3.03). LDL-C showed an inverse association with stroke. The population attributable risk for HDL-C was 37.8% and for hypertension 21.1%. In terms of aetiological subgroups, only low HDL-C was associated with stroke of undetermined aetiology.

CONCLUSIONS

Hypertension, auricular fibrillation, low eGFR, and low HDL-C, plus tobacco use in men, are the main risk factors among patients under 55 years of age with a first ischaemic stroke. We believe that it would be of particular interest to further explore the management of low HDL-C levels as part of preventive strategies in young stroke patients.

The mediating roles of caregiver needs and caregiver readiness in the relation between family resilience and benefit finding in family caregivers of patients with stroke in China

OBJECTIVES

The purpose of this study was to assess the effects of family resilience, caregiver needs, and caregiver readiness on benefit finding for family caregivers of patients with stroke and to examine the mediating role of caregiver needs and caregiver readiness between family resilience and benefit finding.

METHODS

In this cross-sectional study, convenience sampling was designed and used to recruit participants from three general hospitals in Jinan, Shandong Province, China, from February to September 2022, in which 340 participants completed the General Information Questionnaire, Chinese version of the Family Resilience Assessment Scale (C-FRAS), Caregiver Needs Assessment Scale (CNAS) Chinese version of the Caregiver Preparedness Scale (C-CPS), and Caregiver Benefit Finding Scale (CBFS). Model 6 in process version 4.0 was used to test the chain mediation model between family resilience and benefit finding for caregiver needs and caregiver readiness.

RESULTS

Correlation analysis showed that benefit finding in family caregivers was positively associated with family resilience and caregiver readiness and negatively associated with caregiver needs; mediation model tests showed that the total indirect effect of family resilience on benefit finding was 0.163, with the specific mediating effects of caregiver needs and caregiver readiness accounting for 33.74% and 59.51%, and the chain mediating effect of both accounting for 6.75%.

CONCLUSIONS

Family resilience not only directly influences benefit finding for family caregivers but also indirectly affects benefit finding through caregiver needs and caregiver readiness. Caregiver needs and caregiver readiness have a mediating role between family resilience and benefit finding in family caregivers.

A case report about anorexia nervosa and ischemic stroke: what can we learn?

INTRODUCTION

Anorexia Nervosa (AN) is a complex psychiatric illness, characterized by a high risk of developing cardiovascular complications. Given the high risk of vascular diseases in patients with AN, we can assume that patients with severe AN have a high risk of developing ischemic stroke. However, to the best of our knowledge, no reports of patients with AN presenting with ischemic stroke have been published, other than a report of the development of IS during refeeding therapy in patients with severe AN.

CASE PRESENTATION

The present case report is aimed at describing the characteristics of an ischemic stroke occurring in a 19-year-old university student who had a 6-month history of AN. She was a non-smoker, had no relevant medical history and no family history of stroke. Upon hospital admission due to symptoms of stroke (aphasia and facial droop), she exhibited severe malnutrition with a BMI of 12.8 kg/m2. Computerized tomography imaging revealed occlusion of the left M2 branch and a congruous extensive area of hypoperfusion. Further investigations ruled out all common causes of stroke: she had no vascular stenosis, no heart diseases or arrhythmias, and no shunts, and gave negative results in autoimmune, toxicological and thrombophilia screenings.

CONCLUSION

Clinicians should suspect development of severe complications, including ischemic stroke, in patients with severe AN. Further extensive group studies or group-based studies are needed to elucidate the etiology of ischemic stroke in patients with severe AN. This will enable us to develop more precise and effective interventions.

Clinical Characteristics, Functional Outcome, and Socioeconomic Impact of Ischemic Stroke among Young Egyptian Adults

BACKGROUND

Stroke in young patients results in disproportionately high societal cost given the productive life-years lost. Little is known about stroke in young Egyptian patients. We aimed to analyze clinicodemographic characteristics, functional outcome, and socioeconomic impact of ischemic stroke among young Egyptian adults.

METHODS

This is a prospective, observational cohort study of consecutively recruited patients with acute ischemic stroke (AIS), 18-50 years, between September 2022 and September 2023 at a tertiary stroke center in the south of Egypt. We recorded baseline demographic and cardiovascular risk factors, stroke severity, stroke subtype according to the TOAST classification, intravenous thrombolysis, employment, and ambulation status pre- and post-stroke, post-stroke complications, and 90-day functional outcome measured by the modified Rankin Scale (mRS).

RESULTS

Our cohort comprised 210 patients, 38.0 (±7.8) years, 89 (42%) females. Mean NIHSS score was 11.2 (±4.8); in-hospital case fatality was 9% (19 patients). Dyslipidemia (n = 105, 50%), smoking (n = 105, 50%), and hypertension (n = 67, 32%) were the most prevalent cardiovascular risk factors. At 90 days, 58 (29%) patients had a 90-day mRS 0-1 and 53 (26%) met criteria for depression diagnosis. Sixty-nine of the 116 employed individuals (59%) remained out of work after 90 days of stroke, 61 of whom were single earners in their household. 36/60 (60%) thrombolysis-eligible patients received it; an additional 98 otherwise thrombolysis-eligible patients presented >4.5 h from symptom onset. Patients receiving IV thrombolysis were significantly more likely to have resumed full-time work at 90 days (32% vs. 11%, p = 0.006) but with no significant difference in 90-day mRS.

CONCLUSIONS

Young adult AIS patients in Egypt experience high rates of post-stroke depression and face challenges in their ability to work and provide for their families. Since most patients have treatable cardiovascular risk factors and only about two-thirds of eligible patients receive thrombolysis, reinforcing primary prevention, education about early stroke signs, and benefits of acute can improve outcomes and have significant potential societal benefit.

Risk Factors of Premature Atherosclerotic Cardiovascular Disease in China: A Longitudinal Analysis of the China Health and Nutrition Survey Cohort

The burden of premature atherosclerotic cardiovascular disease (ASCVD) has increased rapidly in China. Using the China Health and Nutrition Survey (CHNS) data, we assessed the risk factors of premature ASCVD (age of diagnosis: <55 years for men and <65 years for women). Propensity score matching was used to reduce selection bias. Multivariable Cox proportional-hazards analyses indicated that factors associated with increased risk of premature ASCVD included hypertension (adjusted hazard ratio [HRadj.] = 1.68), obesity (HRadj. = 1.64), and high carbohydrate intake (HRadj. = 1.46). Conversely, participants with medical insurance (HRadj. = 0.42), high urbanization index (HRadj. = 0.53), and high household income (HRadj. = 0.48) had lower risk of premature ASCVD. When comparing premature vs non-premature ASCVD participants, those who were obese (HRadj. = 2.08) or living in more urbanized areas had higher hazards of early onset (HRadj. = 2.29).

Evaluating the risk of ischemic stroke at a young age in patients with autoimmune inflammatory rheumatic diseases: a population-based cohort study in Taiwan

Background

Recent studies have demonstrated an increased incidence of ischemic stroke among patients with certain autoimmune inflammatory rheumatic diseases (AIIRDs). However, the associations between young stroke and AIIRDs have not been fully investigated. This study aimed to evaluate the risk of ischemic stroke among young patients with AIIRDs.

Methods

The National Health Insurance Research Database in Taiwan was utilized to establish cohorts of patients with AIIRDs diagnosed between 2004 and 2015, who were compared with 1,000,000 control participants. Cox proportional hazards regression models were used to calculate the hazard ratio of ischemic stroke and young ischemic stroke for individual AIIRDs after adjustment for relative risk factors.

Results

During the study period, a total of 64,120 patients with AIIRDss and 1,000,000 control patients were identified. The overall mean follow-up time was 5.33 years. There were 223 (0.8%) and 1,923 (0.3%) young ischemic stroke-related hospitalizations among patients with AIIRDs and controls, respectively. The incidence rate of young ischemic stroke was 0.08 in patients with rheumatoid arthritis, 0.08 in patients with Sjögren's syndrome, 0.26 in patients with systemic lupus erythematosus, 0.17 in patients with idiopathic inflammatory myositis, 0.24 in patients with systemic sclerosis, 0.05 in patients with Behçet's disease, and 0.44 in patients with systemic vasculitis, versus 0.05 per 100 person-years in the general population. The adjusted hazard ratios for young ischemic stroke were 1.07 (95% CI 0.70-1.43) for rheumatoid arthritis, 1.39 (95% CI 0.94-2.06) for Sjögren's syndrome, 5.79 (95% CI 4.68-7.17) for systemic lupus erythematosus, 2.07 for idiopathic inflammatory myositis (95% CI 0.98-4.38), 2.79 for systemic sclerosis (95% CI 1.38-5.63), 0.82 for Behçet's disease (95% CI 0.26-2.55), and 4.15 (95% CI 1.96-8.82) for systemic vasculitis.

Conclusions

Patients younger than 50 years with systemic lupus erythematosus, systemic sclerosis, or systemic vasculitis have a significantly elevated risk of developing ischemic stroke. Further research is needed to elucidate the pathogenesis of accelerated atherosclerosis in these AIIRDs.

[Ischemic stroke in men 18-50 years of age]

OBJECTIVE

To evaluate the main modifiable risk factors for ischemic stroke (IS) and features of the course in atherothrombotic, cardioembolic, and lacunar subtypes of IS in men aged 18-50 years.

MATERIAL AND METHODS

The study included 125 men (the mean age was 42.6±5.3 years) who were admitted to the Vascular department before the COVID-19 pandemic and survived for the first 30 days after IS. Information on patients' baseline characteristics, traditional vascular risk factors, and lifestyle risk factors was systematically collected. Neuroimaging, ultrasound and laboratory tests were performed.

RESULTS

Atherothrombotic subtype was identified in 60 patients, lacunar subtype in 46 patients and cardioembolic subtype in 19 patients. In the group as a whole, major risk factors included arterial hypertension (83.2%), dyslipidemia (50.4%), smoking (67.2%), alcohol consumption (29.6%), obesity (16.8%), heart rhythm disorders (12%), and diabetes mellitus (8%).

CONCLUSION

The study revealed the main risk factors, the frequency of which differed depending on the stroke subtype and the age of the patients.

Effect of an educational intervention to increase stroke awareness among Italian high school students: A prospective study in Tuscany

INTRODUCTION

Stroke in young people shares traditional modifiable risk factors with older groups, and greatly affects quality of life. However, evidence on the effectiveness of educational interventions in young populations, aiming at spreading stroke knowledge and enhancing prevention, is still scarce. We evaluated baseline knowledge of stroke and possible improvements after an educational intervention among Italian high school students, also considering differences related to sex and type of school.

SUBJECTS AND METHODS

Using a mixed educational strategy, a prospective evaluation of stroke knowledge was performed in five humanities and sciences (lyceums) and five vocational high schools of Tuscany (students of the 12th and 13th grade). A baseline assessment with a structured questionnaire (21 questions) was followed by a standardized oral presentation, using audiovisual materials. After 3 months, the same questionnaire was re-administered to evaluate the long-term impact of the educational intervention.

RESULTS

Overall, 573 students (50.8% males; age range, 17-19 years) were enrolled; 288 (50.3%) were from lyceums and 285 (49.7%) from vocational schools. Follow-up participation was 97.2%. Baseline performances were comparable between groups for most variables examined. At 3 months, all groups showed a significant improvement from baseline regarding reaction to a stroke event, identification of stroke risk factors, such as smoking (from 62.9% to 83.7%; p < 0.001) and alcohol abuse (from 49.6% to 67.2%; p < 0.001), and symptoms. Knowledge of the existence of stroke units and thrombolysis increased from 25.4% to 60.7% (p < 0.001) and from 35.8% to 84.0% (p < 0.001), respectively.

CONCLUSIONS

Our educational intervention improved stroke awareness in high school students. The effects persisted after 3 months. Improved knowledge in young populations may reduce stroke burden in adult life, increase timely access to therapies, and spread knowledge across families.

Risk Factors for Stroke in the Young (18-45 Years): A Case-Control Analysis of INTERSTROKE Data from 32 Countries

BACKGROUND

It is not clear whether conventional vascular risk factors are responsible for most strokes in patients younger than 45 years of age. Our objective was to evaluate the association of common risk factors with stroke in individuals under 45 years.

METHODS

INTERSTROKE was a case-control study carried out in 32 countries between 2007 and 2015. Patients presenting within 5 days of symptom onset of a first stroke were enrolled as cases. Controls were age and sex matched to cases and had no history of stroke. Cases and controls underwent similar evaluations. Odds ratios (ORs) and population attributable risks (PARs) were calculated to determine the association of various risk factors with all stroke, ischemic stroke, and intracranial hemorrhage, for patients 45 years of age or younger.

FINDINGS

1,582 case-control pairs were included in this analysis. The mean age of this cohort was 38.5 years (SD 6.32). Overall, 71% strokes were ischemic. Cardiac causes {OR: 8.42 (95% confidence interval [CI]: 3.01-23.5)}; binge drinking of alcohol (OR: 5.44 [95% CI: 1.81-16.4]); hypertension (OR: 5.41 [95% CI: 3.40-8.58]); ApoB/ApoA1 ratio (OR: 2.74 [95% CI: 1.69-4.46]); psychosocial stress (OR: 2.33 [95% CI: 1.01-5.41]); smoking (OR: 1.85 [95% CI: 1.17-2.94]); and increased waist-to-hip ratio (OR: 1.69 [95% CI: 1.04-2.75]) were the most important risk factors for ischemic stroke in these young cases. For intracerebral hemorrhage, only hypertension (OR: 9.08 [95% CI: 5.46-15.1]) and binge drinking (OR: 4.06 [95% CI: 1.27-13.0]) were significant risk factors. The strength of association and population attributable risk (PAR) for hypertension increased with age (PAR 23.3% in those <35 years of age, 50.7% in 35-45 years of age).

INTERPRETATION

Conventional risk factors such as hypertension, smoking, binge drinking of alcohol, central obesity, cardiac causes, dyslipidemia, and psychosocial stress are important risk factors for stroke in those younger than 45 years of age. Hypertension is the most significant risk factor in all age groups and across all regions and both stroke subtypes. These risk factors should be identified and modified in early adulthood to prevent strokes in young individuals.

An investigation of the level of stigma and the factors influencing it in the rehabilitation of young and middle-aged stroke patients-a cross-sectional study

BACKGROUND

There are few reported studies on stigma in young and middle-aged stroke patients during the rehabilitation period, however, the rehabilitation period plays a key role in the patients' disease regression. Exploring the level of stigma and the influencing factors in young and middle-aged stroke patients during the rehabilitation period is crucial for determining how to reduce the level of stigma and improve the patients' motivation for rehabilitation treatment. Therefore, this study investigated the level of stigma in young and middle-aged stroke patients and analyzed the factors influencing stigma in order to provide a reference or basis for healthcare professionals to develop effective and targeted stigma intervention programs.

METHODS

Using a convenience sampling method, 285 young and middle-aged stroke patients admitted to the rehabilitation medicine department of a tertiary care hospital in Shenzhen, China, from November 2021 to September 2022 were selected and surveyed using a general information questionnaire, the Stroke Stigma Scale(SSS), the Barthel Index(BI), and the Positive and Negative Emotions Scale(PANAS), and multiple linear regression and smoothed curve fitting were used to analyze the factors influencing the stigma of young and middle-aged stroke patients during the rehabilitation period.

RESULTS

SSS score of 45.08 ± 11.06, univariate analysis of age, occupation, education level, pre-stroke monthly income, insurance type, comorbid chronic disease status, primary caregiver, BI, positive and negative emotion as factors influencing stigma. Multiple linear regression showed that age, pre-stroke monthly income, BI, positive and negative emotions were independent influences on stigma in young and middle-aged stroke patients, explaining 58.0% of the total variance in stigma. A smoothed curve fit revealed a curvilinear relationship between the above influences and stigma.

CONCLUSION

Young and middle-aged stroke patients have a moderate level of stigma. Medical staff should focus on young patients aged 18-44 years, those with high monthly income before the stroke, those with poor self-care ability, and those with low positive and high negative emotion scores, and conduct early assessments and adopt targeted intervention programs according to the influencing factors to reduce the stigma of young and middle-aged stroke patients, improve their motivation for rehabilitation, and help them return to their families and society as soon as possible.

Maternal Dietary Deficiencies in Folic Acid and Choline Result in Larger Damage Volume, Reduced Neuro-Degeneration and -Inflammation and Changes in Choline Metabolites after Ischemic Stroke in Middle-Aged Offspring

Maternal dietary levels of one-carbon (1C) metabolites (folic acid and choline) during pregnancy play a vital role in neurodevelopment. However, the impact of maternal dietary deficiencies on offspring stroke outcomes later in life remains undefined. The aim of this study was to investigate the role of maternal dietary deficiencies in folic acid and choline on ischemic stroke outcomes in middle-aged offspring. Female mice were maintained on either a control or deficient diet prior to and during pregnancy and lactation. At 10 months of age ischemic stroke was induced in male and female offspring. Stroke outcome was assessed by measuring motor function and brain tissue. There was no difference in offspring motor function; however, sex differences were present. In brain tissue, maternal dietary deficiency increased ischemic damage volume and offspring from deficient mothers had reduced neurodegeneration and neuroinflammation within the ischemic region. Furthermore, there were changes in plasma 1C metabolites as a result of maternal diet and sex. Our data indicate that maternal dietary deficiencies do not impact offspring behavior after ischemic stroke but do play a role in brain histology and one-carbon metabolite levels in plasma. Additionally, this study demonstrates that the sex of mice plays an important role in stroke outcomes.

Factors affecting the quality of life after ischemic stroke in young adults: a scoping review

PURPOSE

To synthesize the body of knowledge on the factors influencing the quality of life (QoL) after ischemic stroke (IS) in young adults.

METHODS

Guidelines regarding the scoping review methodology developed by the Joanna Briggs Institute, and the PRISMA-ScR checklist for a scoping review was used in this paper. A total of 1197 studies were identified through a bibliographic search in Web of Science, MEDLINE, PsycInfo, ScienceDirect, Scopus, and ProQuest Science Database. Articles published between the years 2000-2021 were included.

RESULTS

A total of nine papers were finally selected to respond to the research question. Three studies were prospective longitudinal studies compared QoL between young stroke and age-matched controls from the general population. Across all the analysed studies, 14 variables potentially associated with QoL were identified. QoL in young patients is mainly affected by clinical outcomes after IS (scored by the modified Rankin scale and the Barthel index-favourable initial functional status and higher independence in ADL leads to higher QoL) and psychological factors (post-stroke fatigue and depression-higher levels of fatigue and depression lead to lower QoL). The reviewed studies emphasized the importance of functional outcomes, post-stroke depression, fatigue and anxiety and early return to work.

CONCLUSION

Further longitudinal studies are needed to identify the trajectory of post-stroke psychosocial symptoms over time and other potential predictors of unfavourable long-term QoL, thus specific young stroke rehabilitation and stroke self-management support programmes should be developed (address physical, psychological factors which influence the psychosocial adaptation post-stroke and the perception of the QoL).

Comparison Between First-Ever Ischemic Stroke in Young Adults in 1988-1997 and 2008-2017

Aim

To compare incidence of first-ever acute cerebral infarction, etiology and traditional risk factors in young adults 15-49 years in 1988-1997 and 2008-2017 in Hordaland County, Norway.

Methods

Case-finding of young adults with acute cerebral infarction in 1988-1997 was done retrospectively by computer research from hospital registries in Hordaland County. Young adults with acute cerebral infarction living in the Bergen region in 2008-2017 were prospectively included in a database at Haukeland University Hospital. Traditional risk factors, etiology and modified Rankin scale score on discharge were registered.

Results

Crude average incidence of acute cerebral infarction was 11.4 per 100.000 per year in 1988-1997 and 13.2 per 100.000 per year in 2008-2017 (P=0.04). The prevalence of prior myocardial infarction, angina pectoris, and dyslipidemia were lower in the 2008-2017 cohort (all P<0.05). Atherosclerosis was less common in the 2008-2017 cohort (P<0.001).

Conclusion

The observed incidence of acute cerebral infarction in young adults increased from 1988-1997 to 2008-2017 in Hordaland County. Atherosclerosis was less common in the 2008-2017 cohort.

Incidence of first-ever transient ischemic attack in Eastern Finland

OBJECTIVES

The incidence of stroke has been declining in Finland, as well as in Europe. However, it is unclear whether the incidence of transient ischemic attack (TIA) is also decreasing. In fact, the TIA incidence in the Finnish population has never been reported. Therefore, here we investigated the incidence of TIA in the Eastern Finnish population in 2017.

MATERIALS AND METHODS

All patients with suspected TIA, from a defined catchment area, were referred to a neurological emergency unit at Kuopio University Hospital (KUH) in the Northern Savonia region of Eastern Finland, which had a population of 246,653 in 2017. The original study population comprised TIA patients diagnosed based on the WHO TIA criteria in 2017. Incidence rates were calculated by dividing the number of TIA cases by the number of people in different age groups.

RESULTS

Among 432 patients with a suspected TIA referred to the neurological emergency unit at Kuopio University Hospital in 2017, 293 were living in Northern Savonia and were ultimately diagnosed with TIA after neurological examinations. The number of first-ever TIAs was 211. The crude incidence of all TIA was 122/100,000 inhabitants, and of first-ever TIA was 86/100,000. The age-standardized incidence (European population 2010) of the first-ever TIA was calculated to be 64/100,000. The mean age of first-ever TIA patients was 70 years: 72 years for women versus 68 years for men.

CONCLUSIONS

We found a high incidence of TIA in Eastern Finland.

Diverging Temporal Trends in Stroke Incidence in Younger vs Older People: A Systematic Review and Meta-analysis

Importance

Overall stroke incidence is falling in high-income countries, but data on time trends in incidence of young stroke (ie, stroke in individuals younger than 55 years) are conflicting. An age-specific divergence in incidence, with less favorable trends at younger vs older ages, might be a more consistent underlying finding across studies.

Objective

To compare temporal trends in incidence of stroke at younger vs older ages in high-income countries.

Data Sources

PubMed and EMBASE were searched from inception to February 2022. One additional population-based study (Oxford Vascular Study) was also included.

Study Selection

Studies reporting age-specific stroke incidence in high-income countries at more than 1 time point.

Data Extraction and Synthesis

For all retrieved studies, 2 authors independently reviewed the full text against the inclusion criteria to establish their eligibility. Meta-analysis was performed with the inverse variance-weighted random-effects model. Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline was followed.

Main Outcomes and Measures

The main outcome was age-specific divergence (<55 vs ≥55 years) in temporal trends in stroke incidence (relative temporal rate ratio [RTTR]) in studies extending to at least 2000. RTTRs were calculated for each study and pooled by random-effects meta-analysis, with stratification by administrative vs prospective population-based methodology, sex, stroke subtype (ischemic vs intracerebral hemorrhage vs subarachnoid hemorrhage) and geographical region.

Results

Among 50 studies in 20 countries, 26 (13 prospective population-based and 13 administrative studies) reported data allowing calculation of the RTTR for stroke incidence at younger vs older ages across 2 or more periods, the latest extending beyond 2000. Reported trends in absolute incidence of young individuals with stroke were heterogeneous, but all studies showed a less favorable trend in incidence at younger vs older ages (pooled RTTR = 1.57 [95% CI, 1.42-1.74]). The overall RTTR was consistent by stroke subtype (ischemic, 1.62 [95% CI, 1.44-1.83]; intracerebral hemorrhage, 1.32 [95% CI, 0.91-1.92]; subarachnoid hemorrhage, 1.54 [95% CI, 1.00-2.35]); and by sex (men, 1.46 [95% CI, 1.34-1.60]; women, 1.41 [95% CI, 1.28-1.55]) but was greater in studies reporting trends solely after 2000 (1.51 [95% CI, 1.30-1.70]) vs solely before (1.18 [95% CI, 1.12-1.24]) and was highest in population-based studies in which the most recent reported period of ascertainment started after 2010 (1.87 [95% CI, 1.55-2.27]).

Conclusions and Relevance

Temporal trends in stroke incidence are diverging by age in high-income countries, with less favorable trends at younger vs older ages, highlighting the urgent need to better understand etiology and prevention of stroke at younger ages.

Etiology and risk factors of stroke in young adults: A multicentric study

Objective

The main objective of this research was to assess the risk factors and causes of ischemic stroke in the young population (age less than 50 years).

Methods

This was a prospective multicenter study conducted at Pakistan Atomic Energy Commission General Hospital, Islamabad, and Mayo hospital Lahore from June 2019 to June 2020. In this research, patients with ischemic stroke, aged 15–50 years were included. Prior to noting demographics, each patient gave ethical approval via filling out consent forms. After that, all demographical details including residence, education, gender and age, and socioeconomic status were noted. Risk factors were evaluated on the questionnaire proforma. Outcomes were measured using the modified Rankin scale (MRS) score. Additionally, data were analyzed by using SPSS V26. A P-value of <0.05 was set as statistically significant.

Results

Out of 80 patients, 53 (66.25%) were male, while 27 (33.75%) were female. Six (7.5%) patients were between the ages of 15 and 25 years, 18 (22.5%) patients were between 26 and 35 years, 48 (60%) patients were between the ages of 36 and 45, and eight (10%) patients were between the ages of 46 and 50. According to this research, hypertension was found to be the most frequently occurring risk factor in 28 participants (35%), Diabetes mellitus in 23 patients (28.75%), dyslipidemia in 20 patients (22.5%), and smoking in 18 patients (22.5%). The etiology remained undetermined in 30 patients (37.5%). Most of the patients (87.5%) reported positive functional outcomes (MRS score 0–2). However, 3 (3.75%) patients died during the study period.

Conclusion

This research showed that common risk factors of ischemic stroke in the local young population included hypertension, diabetes mellitus, and smoking, whereas the etiology of stroke remained unidentified in the majority of patients.

Stroke in young adults, stroke types and risk factors: a case control study

BACKGROUND

Stroke is the second leading cause of death above the age of 60 years, and the fifth leading cause in people aged 15 to 59 years old as reported by the World Health Organization global burden of diseases. Stroke in the young is particularly tragic because of the potential to create long-term disability, burden on the victims, their families, and the community at large. Despite this, there is limited data on stroke in young adults, and its risk factors in Uganda. Therefore, we determined the frequency and risk factors for stroke among young adults at Mulago hospital.

METHODS

A case control study was conducted among patients presenting consecutively to the general medical wards with stroke during the study period September 2015 to March 2016. A brain Computerized Tomography scan was performed to confirm stroke and classify the stroke subtype. Controls were patients that presented to the surgical outpatient clinic with minor surgical conditions, matched for age and sex. Social demographic, clinical and laboratory characteristics were assessed for both cases and controls. Descriptive statistics including frequencies, percentages, means, and standard deviation were used to describe the social demographics of case and controls as well as the stroke types for cases. To determine risk factors for stroke, a conditional logistic regression, which accounts for matching (e.g., age and sex), was applied. Odds ratio (with 95% confidence interval) was used as a measure for associations.

RESULTS

Among 51 patients with stroke, 39(76.5%) had ischemic stroke and 12(23.5%) had hemorrhagic stroke. The mean age was 36.8 years (SD 7.4) for stroke patients (cases) and 36.8 years (SD 6.9) for controls. Female patients predominated in both groups 56.9% in cases and 52.9% in controls. Risk factors noted were HIV infection, OR 3.57 (95% CI 1.16-10.96), elevated waist to hip ratio, OR 11.59(95% CI 1.98-68.24) and sickle cell disease, OR 4.68 (95% CI 1.11-19.70). This study found a protective effect of oral contraceptive use for stroke OR 0.27 95% CI 0.08-0.87. There was no association between stroke and hypertension, diabetes, and hyperlipidemia.

CONCLUSION

Among young adults with stroke, ischemic stroke predominated over hemorrhagic stroke. Risk factors for stroke were HIV infection, elevated waist to hip ratio and sickle cell disease.

Trends in hospitalisation for ischaemic stroke in young adults in the region of Murcia (Spain) between 2006 and 2014

INTRODUCTION

Recent studies conducted in Europe and the United States suggest upward trends in both incidence and hospitalisation rates for ischaemic stroke in young adults; however, data for Spain are scarce. This study analyses the trend in hospitalisation due to ischaemic stroke in adults aged under 50 years in the region of Murcia between 2006 and 2014.

METHOD

We performed a retrospective study of patients discharged after hospitalisation due to cerebrovascular disease (CVD); data were obtained from the regional registry of the Minimum Basic Data Set. Standardised rates were calculated, disaggregated by age and CVD subtype. Time trends were analysed using joinpoint regression to obtain the annual calculated standardised rate and the annual percentage of change (APC).

RESULTS

A total of 27 064 patients with CVD were discharged during the 9-year study period. Ischaemic stroke was the most frequent subtype (61.0%). In patients aged 18 to 49 years, the annual number of admissions due to ischaemic stroke increased by 26%, and rates by 29.2%; however, the joinpoint regression analysis showed no significant changes in the trend (APC=2.74%, P≥.05). By contrast, a downward trend was identified in individuals older than 49 (APC=-1.24%, P<.05).

CONCLUSIONS

No significant changes were observed in the rate of hospitalisation due to ischaemic stroke among young adults, despite the decline observed in older adults. Identifying the causes of these disparate trends may be beneficial to the development of specific measures targeting younger adults.

Association of Younger vs Older Ages With Changes in Incidence of Stroke and Other Vascular Events, 2002-2018

Importance

Some studies have reported increasing stroke incidence at younger ages (<55 years) but have often relied only on administrative data, and more population-based studies of adjudicated stroke are required. An understanding of the drivers of any increase in incidence of young stroke also requires comparisons with stroke trends at older ages and with trends in incidence of other vascular events at younger ages.

Objective

To determine temporal changes in incidence of stroke and other major vascular events at younger vs older ages.

Design, Setting, and Participants

Prospective population-based incidence study conducted from April 2002 to March 2018 with a mean catchment population of 94 567 in Oxfordshire, England.

Exposures

Calendar time, premorbid vascular risk factors, and occupation.

Main Outcomes and Measures

Changes in incidence of stroke, transient ischemic attack (TIA), and other major vascular events (myocardial infarction, sudden cardiac death, and peripheral vascular events) stratified by age, sex, diagnostic workup, etiology, and severity.

Results

A total of 2429 incident strokes were ascertained (mean age, 73.6 [SD, 14.4] years; 51.3% female). From 2002-2010 to 2010-2018, stroke incidence increased significantly among participants younger than 55 years (incidence rate ratio [IRR], 1.67; 95% CI, 1.31-2.14) but fell significantly among participants aged 55 years or older (IRR, 0.85; 95% CI, 0.78-0.92; P < .001 for difference). The significant increase in incidence at younger than 55 years was independent of sex, stroke severity, pathological subtype, and changes in investigation and was also seen for TIA (IRR, 1.87; 95% CI, 1.36-2.57) but not for myocardial infarction and other major vascular events (IRR, 0.73; 95% CI, 0.58-0.93). Although TIA and stroke at younger than 55 years were significantly associated with diabetes (risk ratio [RR], 3.47; 95% CI, 2.54-4.74), hypertension (RR, 2.52; 95% CI, 2.04-3.12), current smoking (RR, 2.38; 95% CI, 1.92-2.94), and obesity (RR, 1.36; 95% CI, 1.07-1.72), the significant increase in incidence from 2002-2010 to 2010-2018 was still seen in individuals without these risk factors. The increase was greatest in professional/managerial occupations (IRR, 2.52; 95% CI, 1.75-3.62) and least in partially skilled/unskilled occupations (IRR, 1.17; 95% CI, 0.79-1.74). The proportion of TIAs and strokes among those younger than 55 years without known vascular risk factors increased significantly over time (45 [30.4%] vs 115 [42.4%]; absolute difference, 12.0%; 95% CI, 2.6-21.5), especially in patients with cryptogenic events (10 [18.5%] vs 63 [49.2%]; absolute difference, 30.7%; 95% CI, 17.2-44.2; P < .001; P = .002 for heterogeneity).

Conclusions and Relevance

Comparing persons living in Oxfordshire, England, in 2002-2010 vs 2010-2018, there was a significant increase in stroke incidence in those younger than 55 years, but a decrease in those aged 55 years or older. Given the absence of this divergence for other vascular events, further research is needed to understand the causes of this difference.

Understanding and Predicting Cognitive Improvement of Young Adults in Ischemic Stroke Rehabilitation Therapy

Accurate early predictions of a patient's likely cognitive improvement as a result of a stroke rehabilitation programme can assist clinicians in assembling more effective therapeutic programs. In addition, sufficient levels of explainability, which can justify these predictions, are a crucial requirement, as reported by clinicians. This article presents a machine learning (ML) prediction model targeting cognitive improvement after therapy for stroke surviving patients. The prediction model relies on electronic health records from 201 ischemic stroke surviving patients containing demographic information, cognitive assessments at admission from 24 different standardized neuropsychology tests (e.g., TMT, WAIS-III, Stroop, RAVLT, etc.), and therapy information collected during rehabilitation (72,002 entries collected between March 2007 and September 2019). The study population covered young-adult patients with a mean age of 49.51 years and only 4.47% above 65 years of age at the stroke event (no age filter applied). Twenty different classification algorithms (from Python's Scikit-learn library) are trained and evaluated, varying their hyper-parameters and the number of features received as input. Best-performing models reported Recall scores around 0.7 and F1 scores of 0.6, showing the model's ability to identify patients with poor cognitive improvement. The study includes a detailed feature importance report that helps interpret the model's inner decision workings and exposes the most influential factors in the cognitive improvement prediction. The study showed that certain therapy variables (e.g., the proportion of memory and orientation executed tasks) had an important influence on the final prediction of the cognitive improvement of patients at individual and population levels. This type of evidence can serve clinicians in adjusting the therapeutic settings (e.g., type and load of therapy activities) and selecting the one that maximizes cognitive improvement.

Neuroprotective, Anti-inflammatory Effect of Furanochrome, Visnagin Against Middle Cerebral Ischemia-Induced Rat Model

In recent years, the medical field had significantly progressed to a greater extent which was evidenced with increased life expectancy and decreased mortality rate. Due to the growth of medical field, numerous communicable diseases are prevented and eradicated, whereas the non-communicable disease incidence has been increased globally. One such non-communicable disease which threatens the global population is stroke. Stroke tends to be the second leading cause of death and disability in older population. In lower- and middle-income countries, increased incidence rate of stroke was also evidenced in younger population which is alarming. Lifestyle changes, poor physical activity, stress, consumption of alcohol, oral contraception, and smoking tend to be the causative agents of stroke. Since thrombus formation is the major pathology of stroke, drugs were targeted to thrombolysis. Currently thrombolytic, antiplatelet, and anticoagulant therapies were given for the stroke patients. But the recovery rate of stroke patients with available drugs is very slow. Hence, it is a need of today to discover a drug with increased recovery rate and decreased or nil side effects. Phytochemicals are the best options to treat such non-communicable chronic diseases. Visnagin is one such compound which is used to regulate blood pressure, treat kidney stones, tumors of bile duct, renal colic, and whooping cough. It possesses anti-inflammatory, neuroprotective, and cardioprotective properties; it was also proven to treat epileptic seizures. In this study, the anti-ischemic effect of a furanochrome visnagin was assessed in in vivo rat model. Middle cerebral ischemic/reperfusion was induced in healthy male Sprague Dawley rats and treated with different concentrations of visnagin. The neuroprotective effect of visnagin against cerebral ischemia-induced rats was assessed by analyzing the neurological score, brain edema, infract volume, and Evans blue leakage. The anti-inflammatory property of visnagin was assessed by quantifying proinflammatory cytokines in serum and brain tissues of cerebral ischemia-induced rats. Prostaglandin E-2, COX-2, and NFκ-β were estimated to assess the anti-ischemic effect of visnagin. Histopathological analysis with H&E staining was performed to confirm the neuroprotective effect of visnagin against cerebral ischemia. Our results authentically confirm that visnagin has prevented the inflammation in brain region of cerebral ischemia-induced rats. The neurological scoring and the quantification of PGE-2, COX-2, and NFκ-β prove the anti-ischemic effect of visnagin. Furthermore, the histopathological analysis of hippocampal region provides evidence to the neuroprotective effect of visnagin against cerebral ischemia. Overall, our study confirms visnagin as a potent alternative drug to treat stroke.

Patients Hospitalized for Ischemic Stroke and Intracerebral Hemorrhage in France: Time Trends (2008-2019), In-Hospital Outcomes, Age and Sex Differences

BACKGROUND

Rates of patients hospitalized for stroke increased among people aged under 65 years in France, as has been found in other countries.

METHODS

To analyze time trends in the rates of patients hospitalized for ischemic stroke (IS) and intracerebral hemorrhage (ICH) in France between 2008 and 2019 and determine related short-term outcomes mainly, we selected all patients hospitalized for stroke using the French national hospital database.

RESULTS

The average annual percentage change in the rates of patients hospitalized for IS increased significantly in men and women aged 50-64 years (+2.0%) and in men aged 18-34 years (+1.5%) and 35-44 years (+2.2%). A decrease in the average annual percentage change was observed for IS among people aged over 75 years and among those over 50 years for ICH. After adjustment on confounding factors, women were less likely to die in hospital. Case fatality rates decreased overtime in all age groups for both sexes, with a more pronounced decrease for IS than ICH.

CONCLUSIONS

The increasing trend of IS among adults under 65 years is ongoing, highlighting the urgent need for stroke prevention programs in that age. For the first time, we recorded a decrease in the rates of patients hospitalized for ICH among the population over 50 years.

Lipoprotein(a), Immune Cells and Cardiovascular Outcomes in Patients with Premature Coronary Heart Disease

The detection of lipoprotein(a) [Lp(a)] in the artery wall at the stage of lipid-bands formation may indicate that it participates in the atherosclerosis local nonspecific inflammatory process. Innate immune cells are involved in atherogenesis, with monocytes playing a major role in the initiation of atherosclerosis, while neutrophils can contribute to plaque destabilization. This work studies the relationship between Lp(a), immune blood cells and major adverse cardiovascular events (MACE) in patients with the early manifestation of coronary heart disease (CHD). The study included 200 patients with chronic CHD, manifested up to the age of 55 in men and 60 in women. An increased Lp(a) concentration [hyperLp(a)] was shown to predict cardiovascular events in patients with premature CHD with long-term follow-up. According to the logistic regression analysis results, an increase in the monocyte count with OR = 4.58 (95% CI 1.04–20.06) or lymphocyte-to-monocyte ratio with OR = 0.82 (0.68–0.99), (p < 0.05 for both) was associated with MACE in patients with early CHD, regardless of gender, age, classical risk factors, atherogenic lipoproteins concentration and statin intake. The combination of an increased monocyte count and hyperLp(a) significantly increased the proportion of patients with early CHD with subsequent development of MACE (p = 0.02, ptrend = 0.003). The odds of cardiovascular events in patients with early CHD manifestation were highest in patients with an elevated lymphocyte-to-monocyte ratio and an elevated Lp(a) level. A higher neutrophil blood count and an elevated neutrophil-to-lymphocyte ratio determined the faster development of MACE in patients with a high Lp(a) concentration. The data obtained in this study suggest that the high atherothrombogenicity of Lp(a) is associated with the “inflammatory” component and the innate immune cells involvement in this process. Thus, the easily calculated immunological ratios of blood cells and Lp(a) concentrations can be considered simple predictors of future cardiovascular events.

Transition in Incidence Rate of Hospitalised Stroke and Case Fatality Rate in the Hunter Region, Australia, 2001-2019: A Prospective Hospital-Based Study

INTRODUCTION

Continuous surveillance of stroke admissions has been conducted in the Hunter region, Australia, over the past two decades. We aimed to describe the trends in incidence rates of hospitalised stroke and case-fatality rates in this region, 2001-2019.

METHODS

From a hospital-based stroke registry, data for admitted adult stroke patients residing in the Hunter region were collected using ICD-10 codes for ischemic and haemorrhagic stroke. Negative binomial regression and logistic regression analysis were used to analyse trends for age-standardised and age-specific incidence rates of hospitalised stroke and 28-day case-fatality rates.

RESULTS

A total of 14,662 hospitalisations for stroke in 13,242 individuals were registered. The age-standardised incidence rate declined from 123 per 100,000 population in the 2001-2005 epoch to 96 in the 2016-2019 epoch (mean annual change -2.0%, incidence rate ratio (IRR) = 0.980 [95%CI: 0.976-0.984]). Age-specific analyses identified significant reduction in the group aged 75-84 (1039 per 100,000 population in 2001-2005 to 633 in 2016-2019, annual change -3.5%, IRR= 0.965 [95%CI: 0.960-0.970]). The 28-day case-fatality rates fluctuated over time (18.5% in 2001-2005, 20.8% in 2010-2015, and 17.8% in 2016-2019).  Projected population aging suggests annual volume of patients with new stroke will increase by 77% by 2041 if incidence rates remain unchanged at the 2016-2019 level.

CONCLUSION

Although age-standardised hospitalised stroke incidence rates have declined in the Hunter region, the health system will face an increase in stroke hospitalisations related to the aging population.

Vascular risk factors and stroke risk across the life span: A population-representative study of half a million people

Background:

The incidence of stroke in developed countries is increasing selectively in young individuals, but whether this is secondary to traditional vascular risk factors is unknown.

Methods:

We used the Canadian Community Health Survey from 2000 to 2016 to create a large population-representative cohort of individuals over the age of 30 and free from prior stroke. All analyses were stratified by age decile. We linked with administrative databases to determine emergency department visits or hospitalizations for acute stroke until December 2017. We calculated time trends in risk factor prevalence (hypertension, diabetes, obesity, and smoking) using meta-regression. We used Cox proportional hazard models to evaluate the association between vascular risk factors and stroke risk, adjusted for demographic, co-morbid, and social variables. We used competing risk regression to account for deaths and calculated population-attributable fractions. In a sensitivity analysis, we excluded those with prior heart disease or cancer.

Results:

We included 492,400 people in the analysis with 8865 stroke events over a median follow-up time of 8.3 years. Prevalence of hypertension, diabetes, and obesity increased over time while smoking decreased. Associations of diabetes, hypertension, and obesity with stroke risk were progressively stronger at younger age (adjusted hazard ratio for diabetes was 4.47, 95% confidence interval (CI) = 1.95–10.28 at age 30–39, vs 1.21, 95% CI = 0.93–1.57 at age 80+), although the obesity association was attenuated with adjustment. Smoking was associated with higher risk of stroke without a gradient across age deciles, although had the greatest population-attributable fraction at younger age. The hazard ratio for stroke with multiple concurrent risk factors was much higher at younger age (adjusted hazard ratio for 3–4 risk factors was 8.60, 95% CI = 2.97–24.9 at age 30–39 vs 1.61, 95% CI = 0.88–2.97 at age 80+) and results were consistent when accounting for the competing risk of death and excluding those with prior heart disease or cancer.

Conclusions:

Diabetes and hypertension were associated with progressively elevated relative risk of stroke in younger individuals and prevalence was increasing over time. The association of obesity with stroke was not significant after adjustment for other factors. Smoking had the greatest prevalence and population-attributable fraction for stroke at younger age. Our findings assist in understanding the relationship between vascular risk factors and stroke across the life span and planning public health measures to lower stroke incidence in the young.

Evaluation of a Newly Developed Smartphone App for Risk Factor Management in Young Patients With Ischemic Stroke: A Pilot Study

Background: Efficient treatment of modifiable vascular risk factors decreases reoccurrence of ischemic stroke, which is of uttermost importance in younger patients. In this longitudinal pilot study, we thus assessed the effect of a newly developed smartphone app for risk factor management in such a cohort. Methods: The app conveys key facts about stroke, provides motivational support for a healthy lifestyle, and a reminder function for medication intake and blood pressure measurement. Between January 2019 and February 2020, we consecutively invited patients with ischemic stroke aged between 18 and 55 years to participate. Patients in the intervention group used the app between hospital discharge and 3-month follow-up. The control group received standard clinical care. Modifiable risk factors (physical activity, nutrition, alcohol consumption, smoking behavior, obesity, and hypertension) were assessed during the initial hospital stay and at a dedicated stroke outpatient department three months post-stroke. Results: The study cohort comprised 21 patients in the app intervention group (62% male; age = 41 ± 11 years; education = 12 ± 3 years) and 21 sex-, age- and education-matched control patients with a comparable stroke risk factor profile. Baseline stroke severity was comparable between groups (intervention: median NIHSS = 3; control: median NIHSS = 4; p = 0.604). Three months post-stroke, patients in the intervention group reported to be physically almost twice as active (13 ± 9 h/week) compared to controls (7 ± 5 h/week; p = 0.022). More intense app usage was strongly associated with higher physical activity (r = 0.60, p = 0.005) and lower consumption of unhealthy food (r = -0.51, p = 0.023). Smoking behavior (p = 0.001) and hypertension (p = 0.003) improved in all patients. Patients in the intervention group described better self-reported health-related quality of life three months post-stroke (p = 0.003). Conclusions: Specifically designed app interventions can be an easily to implement and cost-efficient approach to promote a healthier lifestyle in younger patients with a stroke.

Young individuals with stroke in rehabilitation: a cohort study

Stroke in younger populations is a public health crisis and the prevalence is rising. Little is known about the progress of younger individuals with stroke in rehabilitation. Characterization of the course and speed of recovery is needed so that rehabilitation professionals can set goals and make decisions. This was a cohort study with data extracted from electronic medical records. Participants were 408 individuals diagnosed with stroke who participated in inpatient rehabilitation in an urban, academic medical center in the USA. The main predictor was age which was categorized as (18-44, 45-64, 65-74 and 75+). Outcomes included baseline-adjusted discharge functional independence measure (FIM) scores and FIM efficiency. In linear regression models for FIM scores, the reference category was the youngest age group. The oldest group was discharged with significantly lower FIM total (B = -8.84), mobility (B = -4.13), self-care (B = -4.07) and cognitive (B = -1.57) scores than the youngest group after controlling for covariates. The 45-64 group also finished with significantly lower FIM total (B = -6.17), mobility (B = -2.61) and self-care (B = -3.01) scores than youngest group. FIM efficiencies were similar for all ages in each of the FIM scales. Younger individuals with stroke make slightly greater functional gains compared to older individuals with stroke, but other factors, such as admission scores, are more important and the rates of recovery may be similar.

Toward Personalized Web-Based Cognitive Rehabilitation for Patients With Ischemic Stroke: Elo Rating Approach

Background

Stroke is a worldwide cause of disability; 40% of stroke survivors sustain cognitive impairments, most of them following inpatient rehabilitation at specialized clinical centers. Web-based cognitive rehabilitation tasks are extensively used in clinical settings. The impact of task execution depends on the ratio between the skills of the treated patient and the challenges imposed by the task itself. Thus, treatment personalization requires a trade-off between patients’ skills and task difficulties, which is still an open issue. In this study, we propose Elo ratings to support clinicians in tasks assignations and representing patients’ skills to optimize rehabilitation outcomes.

Objective

This study aims to stratify patients with ischemic stroke at an early stage of rehabilitation into three levels according to their Elo rating; to show the relationships between the Elo rating levels, task difficulty levels, and rehabilitation outcomes; and to determine if the Elo rating obtained at early stages of rehabilitation is a significant predictor of rehabilitation outcomes.

Methods

The PlayerRatings R library was used to obtain the Elo rating for each patient. Working memory was assessed using the DIGITS subtest of the Barcelona test, and the Rey Auditory Verbal Memory Test (RAVLT) was used to assess verbal memory. Three subtests of RAVLT were used: RAVLT learning (RAVLT075), free-recall memory (RAVLT015), and recognition (RAVLT015R). Memory predictors were identified using forward stepwise selection to add covariates to the models, which were evaluated by assessing discrimination using the area under the receiver operating characteristic curve (AUC) for logistic regressions and adjusted R² for linear regressions.

Results

Three Elo levels (low, middle, and high) with the same number of patients (n=96) in each Elo group were obtained using the 50 initial task executions (from a total of 38,177) for N=288 adult patients consecutively admitted for inpatient rehabilitation in a clinical setting. The mid-Elo level showed the highest proportions of patients that improved in all four memory items: 56% (54/96) of them improved in DIGITS, 67% (64/96) in RAVLT075, 58% (56/96) in RAVLT015, and 53% (51/96) in RAVLT015R (P<.001). The proportions of patients from the mid-Elo level that performed tasks at difficulty levels 1, 2, and 3 were 32.1% (3997/12,449), 31.% (3997/12,449), and 36.9% (4595/12,449), respectively (P<.001), showing the highest match between skills (represented by Elo level) and task difficulties, considering the set of 38,177 task executions. Elo ratings were significant predictors in three of the four models and quasi-significant in the fourth. When predicting RAVLT075 and DIGITS at discharge, we obtained R²=0.54 and 0.43, respectively; meanwhile, we obtained AUC=0.73 (95% CI 0.64-0.82) and AUC=0.81 (95% CI 0.72-0.89) in RAVLT075 and DIGITS improvement predictions, respectively.

Conclusions

Elo ratings can support clinicians in early rehabilitation stages in identifying cognitive profiles to be used for assigning task difficulty levels.

Transient Ischemic Attack (TIA) Incidence with Geographic Information Systems (GIS) Mapping for Stroke Prevention Interventions

Objectives:

GIS mapping as a public health tool has been increasingly applied to chronic disease control. While evaluating TIA incidence from an existing regional stroke registry in Ludhiana city, India, we aim to apply the innovative concept of regional TIA GIS mapping for planning targeted stroke prevention interventions.

Methods:

TIA patient data was obtained from hospitals, scan centers and general practitioners from March 2010 to March 2013 using WHO-Stroke STEPS based surveillance as part of establishing a population-based stroke registry in Ludhiana city. From this registry, patients with TIA (diagnosed by MRI image-based stroke rule-out, or clinically) were chosen and data analyzed.

Results:

A total of 138 TIA patients were included in the final analysis. The annual TIA incidence rate for Ludhiana city was 7.13/100,000 (95% confidence interval: 5.52 to 8.74) for 2012-2013. Mean age was 58.5 ± 13.9 years (range: 22-88 years) and 87 (63%) were men. Majority of the TIA cases had anterior circulation TIAs. Hypertension (87.4%) was the most common risk factor. Using Geographic Information System (GIS) mapping, high TIA incidence was seen in central, western, and southern parts and clustering of TIA cumulative incidence was seen in the central part of Ludhiana city.

Conclusion:

Incidence rate of TIA was lower than that expected from a low- and middle-income country (LMIC). TIA GIS mapping, looking at regional localization, can be a novel option for developing targeted, cost-effective stroke prevention programs.

Characterizing and Profiling microRNAs in Dogs Undergoing Induced Ischemic Brain Stroke After Middle Cerebral Artery Occlusion Under Fluoroscopic Guidance

Purpose

Ischemic stroke of the brain is still considered one of the most common causes of disability and death in developed and developing countries in human beings despite advances in medicine and technology. This study was conducted to characterize and profile tens of induced biomarkers (microRNAs) after experimentally inducing regional ischemic stroke of the brain by occluding the middle cerebral artery under fluoroscopic guidance using an autologous blood clot.

Patient and Methods

A total of six healthy dogs were recruited for this study. The microRNAs were profiled in the blood and urine before and after occluding the middle cerebral artery using genetic techniques.

Results

The very highly expressed genes were comprised within cluster A, followed by cluster D in both 24 and 48-hour brain samples. Clusters B and C revealed down-regulated genes, while miRNAs remained up-regulated in the 24-hour samples merely in cluster F. Upregulated genes at 48 hours of reperfusion were included in cluster E. On the other hand, changes were observed after a day on the cluster G genes. Exclusive upregulation was notified after 2 days due to the changes in mIR-138. The normalized gene expression in the test sample is witnessed through Fold-Change, which divides the control sample’s normalized gene expression. Moreover, fold-change has emerged as a significant approach for representing fold-regulation.

Conclusion

The microRNAs expression in blood and urine may have a potential role in the diagnosis, prognosis, and assessment of therapy associated with cerebral artery occlusion under fluoroscopic guidance.

Family History of Stroke is Associated with Greater Prevalence of Certain Risk Factors and Self-Reported Stroke Symptoms

OBJECTIVES

Family history of stroke increases stroke risk, however mechanisms underlying this association remain unclear. We investigated whether family history of stroke is related to increased prevalence of stroke risk factors, unhealthy behaviors and self-reported stroke symptoms in middle-aged adults.

MATERIALS AND METHODS

In a cross-sectional study conducted from November 2018 to January 2021 in 100 primary care facilities in Poland we evaluated adults aged 40-65 years (n = 2207, women 57.4%, median age 55 years) for stroke risk factors, healthy behaviors, family history of stroke, self-reported stroke symptoms and stroke knowledge using structured questionnaires. Patients were categorized based on family history of stroke defined as ≥1 first-degree relative with documented stroke.

RESULTS

Family history of stroke was reported by 571 (25.9%) individuals who were older (median age 56 vs. 54 years, p = 0.00001) and after adjustment for age more frequently suffered from hypertension (61.5% vs. 53.7%, p = 0.024) and prior transient ischemic attack (2.1% vs. 0.9%, p = 0.019), but not other risk factors. However, they were less obese (34.5% vs. 39.1%, p = 0.03). Women, but not men, with family history of stroke (n = 339, 26.8%) had greater prevalence of atrial fibrillation (7.4% vs. 3.9%, p = 0.037). Family history of stroke was associated with higher prevalence of any self-reported stroke symptom (32.9% vs. 23.2%, p < 0.00001), but not with unhealthy dietary behaviors or low level of knowledge about stroke.

CONCLUSIONS

Family history of stroke is associated with greater prevalence of certain risk factors and self-reported stroke symptoms, which indicates the need for closer surveillance of middle-aged individuals at risk.

Epidemiology and risk factors for stroke in young individuals: implications for prevention

PURPOSE OF REVIEW

Summarize and examine the epidemiology, etiologies, risk factors, and treatment of stroke among young adults and highlight the importance of early recognition, treatment, and primordial prevention of risk factors that lead to stroke.

RECENT FINDINGS

Incidence of stroke, predominantly ischemic, among young adults has increased over the past two decades. This parallels an increase in traditional risk factors such as hypertension, diabetes, and use of tobacco, and use of illicit substances among young stroke patients. Compared to older patients, there is a much higher proportion of intracerebral and subarachnoid hemorrhage in young adults. The cause of ischemic stroke in young adults is also more diverse compared to older adults with 1/3rd classified as stroke of undetermined etiology due to inadequate effort or time spent on investigating these diverse and rare etiologies. Young premature Atherosclerotic Cardiovascular Disease patients have suboptimal secondary prevention care compared to older patients with lower use of antiplatelets and statin therapy and lower adherence to statins.

SUMMARY

Among young patients, time-critical diagnosis and management remain challenging, due to atypical stroke presentations, vast etiologies, statin hesitancy, and provider clinical inertia. Early recognition and aggressive risk profile modification along with primary and secondary prevention therapy optimization are imperative to reduce the burden of stroke among young adults and save potential disability-adjusted life years.

Development and initial validation of a patient-centered stroke outcome measure in young stroke survivors

BACKGROUND AND PURPOSE

This study was undertaken to develop a patient-centered stroke outcome measure and initial validation of the proposed Young Stroke Questionnaire (YSQ).

METHODS

This study assessed the reliability and discriminant validity of the YSQ. The initial questionnaire evolved from a focus group comprised of six young stroke survivors and six stroke neurologists centralized around four patient-centered domains. To determine the reliability and discriminant validity of the YSQ, 100 young stroke survivors were recruited and provided consent. Standardized clinical assessments completed included the modified Rankin Scale (mRS), National Institutes of Health Stroke Scale, and Stroke Impact Scale. Additionally, all patients were asked to complete the patient-centered YSQ.

RESULTS

Of the 100 enrolled patients in the study (mean age ± standard deviation = 49 ± 11.3, 58% females, 53% African American, 44% White), Cronbach alpha for all domains was >0.7. Moreover, Cronbach alpha for entire questionnaire was >0.9, indicating that the scale, with four subdomains, is internally consistent and reproducible. Discriminant validity of the scale was assessed by comparing the means of each subdomain of the YSQ among healthy subjects to the groups of stroke patients as defined by the mRS. The YSQ was able to differentiate subjects with good outcome (mRS = 0-1) from subjects with varying degree of disability as defined by the mRS (p = 0.026).

CONCLUSIONS

Standardized clinical assessments are not sensitive to disabilities in young stroke survivors. When compared to standardized clinical assessments, the YSQ is significantly capable of differentiating the young survivor perspective of the impact of stroke in all four subdomains.

Epigallocatechin Gallate Alleviates Down-Regulation of Thioredoxin in Ischemic Brain Damage and Glutamate-Exposed Neuron

Epigallocatechin gallate (EGCG) is one of polyphenol that is abundant in green tea. It has anti-oxidative activity and exerts neuroprotective effects in ischemic brain damage. Ischemic conditions induce oxidative stress and result in cell death. Thioredoxin is a small redox protein that plays an important role in the regulation of oxidation and reduction. This study was designed to investigate the regulation of thioredoxin by EGCG in ischemic brain damage. Middle cerebral artery occlusion (MCAO) was performed to induce focal cerebral ischemia in male Sprague-Dawley rats. The EGCG (50 mg/kg) or was administered before MCAO surgical operation. Neurological behavior test, reactive oxygen species (ROS), and lipid peroxidation (LPO) measurement were performed 24 h after MCAO. The cerebral cortex was isolated for further experiments. EGCG alleviated MCAO-induced neurological deficits and increases in ROS and LPO levels. EGCG also ameliorated the decrease in thioredoxin expression by MCAO. This finding was confirmed using various techniques such as Western blot analysis, reverse transcription PCR, and immunofluorescence staining. Results of immunoprecipitation showed that MCAO decreases the interaction between apoptosis signal-regulating kinase 1 (ASK1) and thioredoxin, while EGCG treatment attenuates this decrease. EGCG also attenuated decrease of cell viability and thioredoxin expression in glutamate-exposed neuron in a dose-dependent manner. It alleviated the increase of caspase-3 by glutamate exposure. However, this effect of EGCG on caspase-3 change was weakened in thioredoxin siRNA-transfected neurons. These findings suggest that EGCG exerts a neuroprotective effect by regulating thioredoxin expression and modulating ASK1 and thioredoxin binding in ischemic brain damage.

Neurocritical Care of the Pregnant Patient

Purpose of review

To summarize recent changes in management and emerging therapies for pregnant neurocritical care patients.

Recent findings

Diagnostic and treatment options for managing neurologic emergencies in pregnant patients have expanded with both greater understanding of the effects of imaging modalities and medications on pregnancy and application of standard treatments for non-pregnant patients to pregnant populations. Specifically, this includes cerebrovascular diseases (pregnancy-associated ischemic stroke, pregnancy-associated intracerebral hemorrhage, cerebral venous sinus thrombosis), post-maternal cardiac arrest care, seizures and status epilepticus, myasthenia gravis, and fetal somatic support in maternal death by neurologic criteria.

Summary

With the exception of direct abdominal computed tomography (CT), most imaging studies are reasonably safe in pregnancy. When emergent imaging is needed to prevent maternal morbidity or mortality, any CT sequence with or without contrast is appropriate to pursue. Though new safety data on antiplatelets, antihypertensives, thrombolytics, and antiepileptic drugs have increased options for disease management in pregnancy, unfractionated and low-molecular weight heparin remain the safest options for anticoagulation. Early studies on hypothermia, ketamine, and immunomodulating therapies in pregnancy are promising. In myasthenia gravis, new data on adjunct devices may allow more patients to undergo safe vaginal delivery, avoiding cesarean section and the associated risk of crisis. When difficult decisions regarding preterm delivery arise, recent outcome studies can help inform discussion. Lastly, when the feared complication of maternal death by neurologic criteria occurs, fetal somatic support may help to save at least one life.

Temporal Trends in the Incidence of Ischemic Stroke in Young Adults: Dijon Stroke Registry

INTRODUCTION

Stroke is associated with major consequences in terms of socioeconomic impact and lost disability-adjusted life in young victims, thus justifying a careful surveillance of epidemiological trends. This study aimed to assess changes in the incidence of ischemic stroke in young adults over a long period.

METHODS

All cases of first-ever ischemic stroke that occurred among adults aged 18-55 years were prospectively recorded using the population-based Dijon Stroke Registry, from 1985 to 2017. Sex-specific annual incidence rates were calculated and were presented according to 6 time periods. Incidence rate ratios (IRRs) were determined to assess sex differences in stroke incidence.

RESULTS

Over the whole study period, 4,451 patients suffered a first-ever ischemic stroke. Among these patients, 469 (10.5%) were young adults (median age: 46 years, IQR: 39-50; 53.9% men). Incidence rates rose from the study period 2003 to 2007 compared with previous periods and remained stable thereafter, both in men and women. Hence, incidence per 100,000 per year was globally 11.0 (95% CI: 9.4-12.7) before 2003 and 22.9 (20.3-25.6) thereafter. In individuals aged 18-45 years, incidence rates were 5.4 (4.3-6.9) overall, 4.1 (2.7-6.0) in men, and 6.7 (4.9-9.0) in women, before 2003. After 2003, incidence rates rose to 12.8 (10.7-15.1) overall, 12.0 (9.2-15.4) in men, and 13.6 (10.6-17.0) in women. In this age group, the men/women IRR was 0.78 (95% CI: 0.62-1.26, p = 0.08), although sex differences decreased over time (IRR = 0.62; 95% CI: 0.36-1.02, p = 0.046 before 2003, vs. IRR = 0.88; 95% CI: 0.62-1.26, p = 0.48 after 2003). In individuals aged 45-55 years, incidence rates before 2003 were 47 (37-61) in men and 25 (17-35) in women (IRR = 1.90; 95% CI: 1.24-2.97, p < 0.001), and they increased to 82 (67-100) in men and 46 (35-59) in women (IRR = 1.79; 95% CI: 1.29-2.49, p < 0.001) after 2003.

CONCLUSIONS

The incidence of ischemic stroke in young adults increased during the early 2000s and remained stable thereafter. These results highlight the priority need for dedicated prevention strategies for the young to reduce the burden of stroke.

Trends of Stroke Incidence and 28-Day All-Cause Mortality after a Stroke in Malaysia: A Linkage of National Data Sources

Background:

Data on nationwide trends for stroke metrics are crucial to understand the extent of the disease burden to a country’s health system. Yet, this information remains scarce in low- and middle-income countries.

Objectives:

This study investigated trends of stroke incidence and 28-day all-cause mortality after a stroke from 2008 to 2016 in Malaysia, through linkage across national data sources.

Methods:

Hospital admissions with a principal diagnosis of stroke or transient ischemic attack were included. Cases with first stroke were identified through linkage of hospital admission registers where age and sex-standardized trends of stroke incidence and its subtypes were calculated. By linking hospital registers to the National Death Register, the 28-day all-cause mortality rates after a stroke were estimated. Mann-Kendall’s test was used for trend evaluation.

Results:

From 243,765 records, the trend of stroke incidence showed an increase of 4.9% in men and a drop of 3.8% among women. Incidences were higher in men, at 99.1 per 100,000 population in 2008 and 103.9 per 100,000 in 2016 than women (80.3 per 100,000 in 2008 and 77.2 per 100,000 in 2016). There was a substantial increase in stroke incidence among those below 65 years old, with the largest increase of 53.3% in men aged between 35–39 years and 50.4% in women of similar age group. The trend for 28-day all-cause mortality showed a decline for men at –13.1% and women, –10.6%. Women had higher mortality from stroke (22.0% in 2008 and 19.7% in 2016) than men (19.4% in 2008 to 17.2% in 2016).

Conclusion:

This first empirical study on stroke trends in Malaysia revealed a worrying increase in stroke incidence among the younger population. Despite a declining trend, mortality rates remained moderately high especially in women. Comprehensive strategies to strengthen the prevention and management of stroke care are warranted.

Blood Pressure Levels in Young Adulthood and Midlife Stroke Incidence in a Diverse Cohort

Increasing false positive diagnoses may lead to overestimation of stroke incidence, particularly in the young: a cross-sectional study

Background

Stroke incidence is reportedly increasing in younger populations, although the reasons for this are not clear. We explored possible reasons by quantifying trends in neurologically focused emergency department (ED) visits, classification of stroke vs. TIA, and imaging use.

Methods

We performed a retrospective, serial, cross-sectional study using the National Hospital Ambulatory Medical Care Survey to examine time trends in age-stratified primary reasons for visit, stroke/TIA diagnoses, and MRI utilization from 1995 to 2000 and 2005–2015.

Results

Five million eight hundred thousand ED visits with a primary diagnosis of stroke (CI 5.3 M–6.4 M) were represented in the data. The incidence of neurologically focused reason for visits (Neuro RFVs) increased over time in both the young and in older adults (young: + 111 Neuro RFVs/100,000 population/year, CI + 94 − + 130; older adults: + 70 Neuro RFVs/100,000 population/year, CI + 34 − + 108). The proportion of combined stroke and TIA diagnoses decreased over time amongst older adults with a Neuro RFV (OR 0.95 per year, p < 0.01, CI 0.94–0.96) but did not change in the young (OR 1.00 per year, p = 0.88, CI 0.95–1.04). Within the stroke/TIA population, no changes in the proportion of stroke or TIA were identified. MRI utilization rates amongst patients with a Neuro RFV increased for both age groups.

Conclusions

We found, but did not anticipate, increased incidence of neurologically focused ED visits in both age groups. Given the lower pre-test probability of a stroke in younger adults, this suggests that false positive stroke diagnoses may be increasing and may be increasing more rapidly in the young than in older adults.

Nationwide Trends in Incidence and Mortality of Stroke Among Younger and Older Adults in Denmark

OBJECTIVE

To investigate the extent to which the incidence and mortality of a first-time stroke among younger and older adults changed from 2005 to 2018 in Denmark using nationwide registries.

METHODS

We used the Danish Stroke Registry and the Danish National Patient Registry to identify patients 18 to 49 years of age (younger adults) and those ≥50 years of age (older adults) with a first-time ischemic stroke, intracerebral hemorrhage, or subarachnoid hemorrhage. We computed age-standardized incidence rates and 30-day and 1-year mortality risks separately for younger and older adults and according to smaller age groups, stroke subtype, sex, and severity (Scandinavian Stroke Scale score). Average annual percentage changes (AAPCs) were computed to assess temporal trends.

RESULTS

We identified 8,680 younger adults and 105,240 older adults with an ischemic stroke or intracerebral hemorrhage. The incidence rate per 100,000 person-years of ischemic stroke (20.8 in 2005 and 21.9 in 2018, AAPC -0.6 [95% confidence interval (CI) -1.5 to 0.3]) and intracerebral hemorrhage (2.2 in 2005 and 2.5 in 2018, AAPC 0.6 [95% CI -1.0 to 2.3]) remained steady in younger adults. In older adults, rates of ischemic stroke and intracerebral hemorrhage declined, particularly in those ≥70 years of age. Rates of subarachnoid hemorrhage declined, but more so in younger than older adults. Stroke mortality declined over time in both age groups, attributable largely to declines in the mortality after severe strokes. Most trends were similar for men and women.

CONCLUSION

The incidence of ischemic stroke and intracerebral hemorrhage was steady in younger adults from 2005 to 2018, while it dropped in adults >70 years of age. Stroke mortality declined during this time.

Characterisation of recent trends in cardiovascular risk factors in young and middle-aged patients with ischaemic stroke and/or transient ischaemic attack

BACKGROUND

Strokes in the young and middle-aged are associated with a disproportionately large economic and social impact in addition to their clinical effects. Standard Modifiable Cardiovascular Risk Factors (SMuRFs; hypercholesterolaemia, hypertension, diabetes mellitus and smoking) are key drivers of cardiovascular disease including strokes, however recent temporal trends in the younger stroke population have not been well characterised. We aimed to evaluate recent trends of SMuRFs in a cohort of younger patients with ischaemic stroke.

METHODS

Consecutive patients aged <65 years with clinical and/or radiological diagnosis of ischaemic stroke or transient ischaemic attack in a tertiary referral centre (2013-2017) were retrospectively appraised. The demographic and clinical comorbidities of these patients were assessed including their SMuRF profile. The prevalence over time and clinical associations of patients with no SMuRFs were studied and compared to patients with SMuRFs.

RESULTS

Of 487 patients (53.49 ± 9.13 yrs., 60% men) analysed, 23% did not have SMuRFs. The proportion of "non-SMuRF" patients increased over time (p < 0.01) and this trend was not influenced by age (p = 0.48) or gender (p = 0.68). The presence of SMuRFs was not associated with in-hospital outcomes, however patients without SMuRFs were significantly less likely to be discharged on blood pressure (p < 0.01) and lipid-lowering therapies (p = 0.03).

CONCLUSIONS

The proportion of younger stroke patients without SMuRFs is substantial and has increased over time. Our findings highlight the need for further research to better understand the mechanisms underlying stroke development in this population and whether less risk factor treatment in this population could impact longer term outcomes.

Association Between Sociodemographic Determinants and Disparities in Stroke Symptom Awareness Among US Young Adults

BACKGROUND AND PURPOSE

Despite declining stroke rates in the general population, stroke incidence and hospitalizations are rising among younger individuals. Awareness of and prompt response to stroke symptoms are crucial components of a timely diagnosis and disease management. We assessed awareness of stroke symptoms and response to a perceived stroke among young adults in the United States.

METHODS

Using data from the 2017 National Health Interview Survey, we assessed awareness of 5 common stroke symptoms and the knowledge of planned response (ie, calling emergency medical services) among young adults (<45 years) across diverse sociodemographic groups. Common stroke symptoms included: (1) numbness of face/arm/leg, (2) confusion/trouble speaking, (3) difficulty walking/dizziness/loss of balance, (4) trouble seeing in one/both eyes, and (5) severe headache.

RESULTS

Our study population included 24 769 adults, of which 9844 (39.7%) were young adults who were included in our primary analysis, and represented 107.2 million US young adults (mean age 31.3 [±7.5] years, 50.6% women, and 62.2% non-Hispanic White). Overall, 2718 young adults (28.9%) were not aware of all 5 stroke symptoms, whereas 242 individuals (2.7%; representing 2.9 million young adults in the United States) were not aware of a single symptom. After adjusting for confounders, Hispanic ethnicity (odds ratio, 1.96 [95% CI, 1.17-3.28]), non-US born immigration status (odds ratio, 2.02 [95% CI, 1.31-3.11]), and lower education level (odds ratio, 2.77 [95% CI, 1.76-4.35]), were significantly associated with lack of symptom awareness. Individuals with 5 high-risk characteristics (non-White, non-US born, low income, uninsured, and high school educated or lower) had nearly a 4-fold higher odds of not being aware of all symptoms (odds ratio, 3.70 [95% CI, 2.43-5.62]).

CONCLUSIONS

Based on data from the National Health Interview Survey, a large proportion of young adults may not be aware of stroke symptoms. Certain sociodemographic subgroups with decreased awareness may benefit from focused public health interventions.

Subacute ischemic stroke rehabilitation outcomes in working-age adults: The role of aphasia in cognitive functional independence

BACKGROUND

About one-third of adult stroke patients suffer from aphasia when they are discharged from hospital. Aphasia seems to be a negative predictive factor affecting post-stroke functional recovery after rehabilitation, but this association has been scarcely addressed in previous research.

OBJECTIVES

We aim to evaluate the impact of aphasia in cognitive functional outcomes in working-age first-ever ischemic stroke adults.

METHODS

Retrospective observational cohort study. One hundred and thirty ischemic (≤ 64 years old) adult stroke patients (43.07% with aphasia) admitted to a rehabilitation center between 2007 and 2019 were analyzed. Univariate and multivariate linear regressions were performed using state-of-the-art variables (stroke severity, gender, age) extending them with potential confounders (e.g. diabetes, medication for depression). The cognitive subtest (C-FIM) of the Functional Independence Measure (FIM) at discharge and C-FIM gain were the dependent variables.

RESULTS

Patients with aphasia (PWA) had lower C-FIM scores at admission and at discharge. No significant differences were observed in relation to C-FIM gain, C-FIM efficiency, C-FIM effectiveness and length of stay (LOS).C-FIM gain was remarkably higher though non-significant (p = .059) in PWA. Regression analysis identifies C-FIM at admission and aphasia as significant predictors of C-FIM at discharge (R² = 0.72). The same variables plus taking medication for depression predicted C-FIM gain (R² = 0.38).

CONCLUSIONS

We identified no significant differences in C-FIM outcomes (gain, efficiency and effectiveness) either in LOS between PWA and patients without aphasia, though C-FIM differences were significant at admission and discharge. Aphasia was a significant predictor of C-FIM gain and C-FIM at discharge.

Trends in Cardiovascular Mortality Among a Cohort of Children and Young Adults Starting Dialysis in 1995 to 2015

IMPORTANCE

Survival of patients receiving dialysis has improved during the last 2 decades. However, few studies have examined temporal trends in the attributed causes of death (especially cardiovascular-related) in young populations.

OBJECTIVE

To determine temporal trends and risk of cause-specific mortality (ie, cardiovascular and infectious) for children and young adults receiving dialysis.

DESIGN, SETTING, AND PARTICIPANTS

This retrospective cohort study examined the records of children and young adults (aged <30 years) starting dialysis between 1995 and 2015 according to the United States Renal Data System database. Analyses were performed between June 2019 and June 2020. Fine-Gray models were used to examine trends in risk of different cardiovascular-related deaths. Models were adjusted for age, sex, race, neighborhood income, cause of end-stage kidney disease, insurance type, and comorbidities. Analyses were performed separately for children (ie, age <18 years) and young adults (between ages 18 and 30 years). Follow-up was censored at death or administratively, and transplantation was treated as a competing event.

EXPOSURES

Calendar year.

MAIN OUTCOMES AND MEASURES

Cardiovascular cause-specific mortality.

RESULTS

A total of 80 189 individuals (median [interquartile range] age, 24 [19-28] years; 36 259 [45.2%] female, 29 508 [36.8%] Black, and 15 516 [19.3%] Hispanic white) started dialysis and 16 179 experienced death during a median (interquartile range) of 14.3 (14.0-14.7) years of follow-up. Overall, 40.2% of deaths were from cardiovascular-related causes (6505 of 16 179 patients). In adjusted analysis, risk of cardiovascular-related death was stable initially but became statistically significantly lower after 2006 (vs 1995) in those starting dialysis as either children (subhazard ratio [SHR], 0.74; 95% CI, 0.55-1.00) or adults (SHR, 0.90; 95% CI, 0.83-0.98). Risk of sudden cardiac death improved steadily for all age groups, but to a greater degree in children (SHR, 0.31; 95% CI, 0.20-0.47) vs young adults (SHR, 0.64; 95% CI, 0.56-0.73) comparing 2015 vs 1995. Risk of stroke became statistically significantly lower around 2010 (vs 1995) for children (SHR, 0.40; 95% CI, 0.18-0.88) and young adults (SHR, 0.76; 95% CI, 0.59-0.99).

CONCLUSIONS AND RELEVANCE

In this study, the risk of cardiovascular-related death declined for children and young adults starting dialysis during the last 2 decades, but trends differed depending on age at dialysis initiation and the specific cause of death. Additional studies are needed to improve risk of cardiovascular disease in young populations.
