The Impact

Background and Purpose. Residing in “disadvantaged” communities may increase morbidity and mortality independent of individual social resources and biological factors. This study evaluates the impact of population-level disadvantage on incident ischemic stroke likelihood in a multiethnic urban population. Methods. A population based case-control study was conducted in an ethnically diverse community of New York. First ischemic stroke cases and community controls were enrolled and a stroke risk assessment performed. Data regarding population level economic indicators for each census tract was assembled using geocoding. Census variables were also grouped together to define a broader measure of collective disadvantage. We evaluated the likelihood of stroke for population-level variables controlling for individual social (education, social isolation, and insurance) and vascular risk factors. Results. We age-, sex-, and race-ethnicity-matched 687 incident ischemic stroke cases to 1153 community controls. The mean age was 69 years: 60% women; 22% white, 28% black, and 50% Hispanic. After adjustment, the index of community level disadvantage (OR 2.0, 95% CI 1.7–2.1) was associated with increased stroke likelihood overall and among all three race-ethnic groups. Conclusion. Social inequalities measured by census tract data including indices of community disadvantage confer a significant likelihood of ischemic stroke independent of conventional risk factors.

The Impact

There is significant data on the adverse impact of COVID-19 on persons who were poor, minorities, had compromised physical or mental health, or other vulnerabilities prior to the COVID-19 pandemic. A significant portion of the overall Medicare population has such vulnerabilities. The Medicare home health beneficiary population is even more vulnerable than the overall Medicare population based on gender, race, income level, living alone status, and number of chronic conditions. A literature review indicates there is only 1 study on the impact of COVID-19 in Medicare home health on home care workers and none on the impact on home health beneficiaries. The current study is a qualitative study based on interviews of a convenience sample of 48 home care nurses from 9 different home health agencies in New York City between April 1 and August 31, 2020. Six major themes emerged: need for social service supports increased; loneliness and depression increased among patients; physical and mental health conditions became exacerbated; substance use and abuse increased; evidence of domestic violence against patients increased; and there was a limited amount of staff and equipment to care for patients.

Background: Hemorrhagic transformation (HT) of ischemic stroke can have devastating consequences, leading to longer hospitalizations, increased morbidity and mortality. We sought to identify the rate of HT in stroke patients not treated with tPA within a large, biracial population. Methods: The GCNKSS is a population-based stroke epidemiology study from five counties in the Greater Cincinnati region. During 2015, we captured all hospitalized strokes by screening ICD-9 codes 430-436 and ICD-10 codes I60-I68, and G45-46. Study nurses abstracted all potential cases and physicians adjudicated cases, including classifying the degree of HT. Patients treated with thrombolytics were excluded. Incidence rates per 100,000 and associated 95% confidence intervals (CI) were estimated for HT cases, age and sex adjusted to the 2000 US population. Multiple logistic regression was used to examine risk factors associated with HT. Results: In 2015, there were 2301 ischemic strokes included in the analysis. Of these 104 (4.5%) had HT; 23 (22.1%) symptomatic, 55 (52.9%) asymptomatic and 26 (25%) unknown. Documented reasons for not receiving tPA in these patients were: time (71, 68.3%), anticoagulant use (1, 1.0%), other (18,17.3%) and unknown (14, 13.5%), which were not significantly different compared to those without HT. Only 29/104 (18.3%) had HT classified as PH-1 or PH-2. The age, sex and race-adjusted rate of HT was 9.8 (7.9, 11.6) per 100,000. The table shows rates of potential risk factors and the adjusted odds of developing HT. 90 day all-cause case fatality for patients with HT was significantly higher, 27.9% vs. 15.7%, p<0.0001. Conclusion: We found that 4.5% of non-tPA treated IS patients had HT. These patients had more severe strokes, were more likely to have abnormal coagulation tests or anticoagulant use, and were more likely to die within 90 days. We also report the first population-based incidence rate of HT in non-tPA treated of 9.8/100,000, a rate similar to the incidence of SAH.

Material and methods. In the cross-sectional population-based study of general unorganized population of Tomsk aged 25-64 years ultrasound screening examination of the carotid arteries was done for detection of atherosclerotic plaques (plaque). As potential plaque determinants the following factors were studied: age, gender, smoking, low and high density lipoproteins (LDL-C and HDL-C), triglycerides, arterial hypertension, body mass index (BMI), low educational status (LES), high-sensitive C-reactive protein, glucose, diabetes mellitus, antihypertensive and hypolipidemic therapy. Study of relationships was carried out with logistic regression analysis. The error probability of less than 5% was considered statistically significant.Results. In the crude analysis most of the determinants under study showed statistically significant relationship with plaque presence. After adjustment for age and sex, LDL-C, smoking and LES were associated with CAS prevalence. In multivariable regression analysis 9 risk factors appeared to be independently associated with plaque presence, wherein age, male sex, LDL-C, BMI and HDL-C were the most significant. In the participants of 50 years and older the smoking effect was the next in significance after LDL-C.Conclusion. The results obtained focus attention on the comparative value of the major atherogenic risk factors and suggest that currently effective and timely control of LDL-C is of primary importance for prevention of carotid atherosclerosis in the general working-age population. As well the findings of the study evidence that at the population level smoking is still one of the leading atherogenic risk factors.

Background: Intracranial atherosclerotic stenosis (ICAS) and small vessel disease (SVD) may coexist. We investigated the frequency and risk factors for SVD in SAMMPRIS patients and the impact of SVD on stroke recurrence in the medical arm of the trial. Methods: Of 451 patients enrolled in SAMMPRIS, 313 had baseline brain MRIs read centrally for SVD. SVD was defined by any of the following: old lacunar infarction, Fazekas score of 2-3 for white matter hyperintensities, or microbleeds. We compared risk factors in patients with vs. without SVD using Fisher’s exact test (for percentages), independent groups t test (for means) or Wilcoxon rank sum test (for medians), and compared the survival curves of patients with vs. without SVD in the medical arm for ischemic stroke in the territory of the stenotic artery and any ischemic stroke using the logrank test. Results: Of the 313 patients, 161 (51.4%) had SVD on the baseline MRI. Variables that were significantly (p<0.05) higher in patients with SVD were age, diabetes, lipid disorder, baseline SBP, coronary disease, and old infarct in the territory. The Kaplan-Meier curves in the figure show that patients with SVD were at significantly higher risk of any ischemic stroke (p = 0.048) but not stroke in the territory (p = 0.10) compared with patients without SVD. Conclusion: SVD in patients with ICAS is common, especially in patients who are older, diabetic, hyperlipidemic, and have higher SBP. Patients with ICAS and coexistent SVD are at higher risk of any ischemic stroke but may not be at higher risk for stroke in the territory.

BackgroundInjuries are one of the three leading causes of morbidity and mortality for young people internationally. Although community risk factors are modifiable causes of youth injury, there has been limited evaluation of community interventions. Communities That Care (CTC) offers a coalition training process to increase evidence-based practices that reduce youth injury risk factors.MethodUsing a non-experimental design, this study made use of population-based hospital admissions data to evaluate the impact on injuries for 15 communities that implemented CTC between 2001 and 2017 in Victoria, Australia. Negative binomial regression models evaluated trends in injury admissions (all, unintentional and transport), comparing CTC and non-CTC communities across different age groups.ResultsStatistically significant relative reductions in all hospital injury admissions in 0–4 year olds were associated with communities completing the CTC process and in 0–19 year olds when communities began their second cycle of CTC. When analysed by subgroup, a similar pattern was observed with unintentional injuries but not with transport injuries.ConclusionThe findings support CTC coalition training as an intervention strategy for preventing youth hospital injury admissions. However, future studies should consider stronger research designs, confirm findings in different community contexts, use other data sources and evaluate intervention mechanisms.

Aim. To study the impact of birth characteristics on the risk of atopic dermatitis in a twin population. Methods. In a population-based questionnaire study of 10,809 twins, 3–9 years of age, from the Danish Twin Registry, we identified 907 twin pairs discordant for parent-reported atopic dermatitis. We cross-linked with data from the Danish National Birth Registry and performed cotwin control analysis in order to test the impact of birth characteristics on the risk of atopic dermatitis. Results. Apgar score, OR (per unit) = 1.23 (1.06–1.44), P=0.008, and female sex, OR = 1.31 (1.06–1.61), P=0.012, were risk factors for atopic dermatitis in cotwin control analysis, whereas birth anthropometric factors were not significantly related to disease development. Risk estimates in monozygotic and dizygotic twins were not significantly different for the identified risk factors. Conclusions. In this population-based cotwin control study, high Apgar score was a risk factor for atopic dermatitis. This novel finding must be confirmed in subsequent studies.

Abstract Abstract 3993 Poster Board III-929 Background The incidence of stroke in children is estimated at about 2.6 per 100,000 per year. Risk factors include congenital heart malformations, trauma, hemolytic anemias, collagen tissue diseases, inborn metabolic disorders, and infectious diseases. Apart from acquired thrombophilic risk factors, such as the presence of antiphospholipid antibodies, inherited thrombophilias (IT) have been found to be associated with stroke in infants and children. However, results of single studies on the risk of stroke onset associated with IT have been contradictory or inconclusive, mainly due to lack of statistical power. The aim of this study was to estimate the impact of thrombophilia (IT) on risk of childhood stroke via meta-analysis of published observational studies. Methods and Results A systematic search of electronic databases (Medline, EMBASE, OVID, Web of Science, The Cochrane Library) for studies published from 1970 to 2009 was conducted using key words in combination both as MeSH terms and text words. Citations were independently screened by two authors and those meeting the a priori defined inclusion criteria were retained. Data on year of publication, study design, country of origin, number of patients/controls, ethnicity, stroke type (arterial ischemic stroke [AIS]; cerebral venous sinus thrombosis [CSVT]) were abstracted. Publication bias indicator and heterogeneity across studies were evaluated, and summary odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using both fixed-effects and random-effects models. Twenty-one of 185 references found met inclusion criteria. 1698 patients (AIS: 1291; CSVT: 407) and 2913 controls aged neonate to 18 years were enrolled. No significant heterogeneity was discerned across studies, and no publication bias was detected. A statistically significant association with stroke onset was demonstrated for each IT trait evaluated, with no difference found between AIS (table) and CSVT. Summary ORs/CIs (random-effects model) for AIS & CSVT cohorts were as follows: Protein C-deficiency (8.76/4.53-16.96), FV G1691A (3.34/2.66-4.26), FII G20210A (2.50/1.67-3.74), MTHFR T677T (1.61/1.21-2.14), antiphospholipid antibodies (5.84/3.06-11.18), elevated lipoprotein (a) (6.24/4.51-8.64), and combined ITs (8.85/3.32-23.57). Carrier rates reported for antithrombin- or protein S deficiency among patients were 1.5% and 1.6% as compared with 0.06% (p<0.001) and 0.4% (p=0.003) in healthy controls. Conclusions The present meta-analysis indicates that IT serve as risk factors for incident stroke. However, the impact of IT upon outcome and recurrence risk needs to be further investigated.
