Background/Objective: As a primary, pre-specified objective of the population-based Brain Attack Surveillance in Corpus Christi (BASIC) project we studied trends in mortality following ischemic stroke among Mexican Americans (MAs) and non Hispanic whites (NHWs). MAs were previously found to have lower mortality following stroke than NHWs. Methods: We performed active and passive surveillance, and using source documentation, validated all ischemic stroke cases from January, 2000-December, 2010. Deaths were ascertained from the Texas Department of Health through December 31, 2011. Cumulative 30 day and 1 year mortality adjusted for covariates was estimated using log-binomial models with a linear term for year of stroke onset used to model time trends. Pre-specified adjustment factors were: age, sex, prior stroke or TIA, atrial fibrillation, diabetes, heart disease, hypertension, smoking, high cholesterol and stroke severity. Models used data from the entire study period to estimate adjusted mortality among stroke cases in 2000 and 2010, and to calculate projected ethnic differences. Results: There were 1,822 ischemic strokes among NHWs and 2,211 among MAs. Between 2000 and 2010, 30 day and 1 year mortality declined among NHWs, from 8.6% to 5.9% (p=0.14), and 21.7% to 17.0% (p=0.06), respectively. Among MAs, 30 day mortality remained stagnant at 5.6% (p=0.98), and a slight decline from 18.3% to 16.4% was observed for 1 year mortality (p=0.41). While, the ethnic differences in 30 day (p=0.01) and 1 year (p=0.07) mortality were robust in 2000, they were not so in 2010 (30 day, p=0.76; 1 year p=0.78). See figure. MAs are projected to have higher post-stroke mortality by 2022. Conclusions: Overall, mortality following ischemic stroke has declined in the last decade. However, the survival advantage previously documented among MAs vanished by 2010. Further, faster declines in mortality among NHWs than MAs imply a reversal of the survival advantage by approximately 2022.

Using Data

Introduction: Elevated stroke rates in Mexican Americans (MA) compared with non-Hispanic whites (NHW) persisted over the first decade of the 21 st century. Our objective was to investigate recent trends in ischemic stroke (IS) rates by ethnicity and age using data from a longstanding population-based study. Methods: ISs were identified in the Brain Attack Surveillance in Corpus Christi (BASIC) Project (2000-2017) and validated by neurologists using a clinical definition. Race-ethnicity was from medical records. Annual population counts from the US Census estimated the at-risk population. Poisson regression was used to model sex-adjusted rate trends by ethnicity and age. Time was modeled using linear and quadratic terms. Ethnic differences were assessed using interaction terms between ethnicity and time. Results: 4,883 ISs were identified (median age 70 (IQR:59-80); 56% MA). Trends varied by ethnicity and age (figure). In those 45-59, rates increased substantially in NHWs (104%; p<0.001 for rate difference 2000-2017) but decreased in MAs (-21.4%; p=0.04 for rate difference 2000-2017) such that, for the first time, rates were higher in NHWs. In those 60-74, rates declined in both ethnic groups through 2010-2011 but then increased and more steeply in NHWs thereafter. In those ≥75, rates declined in MAs, declined sharply in NHWs through 2012 and then increased. Conclusions: New patterns in stroke have emerged. Ethnic disparities have declined as a result of increasing rates in NHWs most notably in midlife. Reasons for increasing rates in recent years are unclear but suggest renewed attention to prevention.

Background/Objective: We studied the association of being born outside of the U.S. (immigrant) or born in the U.S. (non-immigrant) with 90 day post-stroke outcomes in a population-based stroke study in Texas. Methods: Stroke cases from 2008-2016 were identified from the Brain Attack Surveillance in Corpus Christi (BASIC) project. Outcomes among survivors included ADL/IADL score (higher scores worse) for functional assessment, 3MSE (cognition, lower scores worse), and NIHSS Score (neurologic, higher scores worse). Weighted linear regression models were used to assess the effect of immigration status on the outcomes. Analysis was completed using multiple imputation and inverse probability weighting to account for differential attrition. Results: Of 935 Mexican Americans available for analysis, 83 were immigrants and 852 were non-immigrants. Immigrants had resided in the U.S. on average 47 years. Immigrants were significantly older (69 vs. 66 years), more likely male (60% vs. 49%), more likely to have atrial fibrillation and have less education than non-immigrants (all p<0.05). No differences in hypertension, diabetes, cholesterol, insurance, smoking or other comorbidities existed. The Table provides the data from the fully adjusted models. Immigrants had better functional outcome (mean difference (MD) = -0.22; p=0.02), and no difference for neurologic outcome (MD= -0.15; p=0.15). There was an association of worse cognitive outcome in immigrants (MD= -5.25; p=0.009), however, the association was explained by attenuated after the adjustment for the lower educational attainment in immigrants (MD= -0.79; p=0.64). Conclusions: In this community, there was no evidence of worse stroke outcome among Mexican American immigrants, who had lived in the U.S. for decades, compared with non-immigrants. Further studies of more recent immigrant populations are warranted.

Occupational Goals

Background and Aims: We studied informal (non-paid) caregiving after stroke in a population-based study to determine if differences occurred between Mexican Americans (MAs) and non-Hispanic whites (NHWs). MAs are a less affluent population than NHWs. Family members who provide caregiving may need to interrupt educational and occupational goals to provide this care, which may perpetuate socioeconomic disparities between minority and majority populations. Methods: Between October, 2014 and December, 2016, stroke subjects in Texas, USA, were interviewed 90 days after stroke to determine if family or friends provided informal, unpaid caregiving, and for which activities of daily living (ADLs) they required help. Chi-square tests were used to assess the association of ethnicity and whom provided the caregiving, as well as ethnicity and the ADLs for which they required help. Ethnic differences between MAs and NHWs in receiving informal caregiving were determined using logistic regression. The odds ratio (OR, 95% CI) is reported with NHW as the referent group. Results: 473 subjects answered the caregiving questions. There were no significant differences among the two ethnic groups with respect to age, sex, NIHSS score, marital status, or insurance. MAs were more likely to require help compared with NHWs for walking (p=0.0008), bathing (p=0.0004), hygiene (p=0.0018), eating (p=0.0059), dressing (p<0.0001), moving (p=0.0015) and toileting (p=0.0007). Among all subjects, 144 (30%) received informal caregiving (35% of 300 MAs versus 22% of 173 NHWs). There were no significant ethnic differences among which family member provided the caregiving. MAs were more likely to have informal caregiving OR=1.87 (95% CI 1.11-3.13) adjusted for age, sex, NIHSS, education, insurance and marital status. Conclusions: In this population-based study, MAs required more help than NHWs for assistance with ADLs, and MAs were more likely to receive this help through informal, unpaid caregiving than NHWs. Efforts to help minority and low-resource populations provide stroke care are needed.

Objective:To compare 18-year (2000-2017) temporal trends in ischemic stroke rates by ethnicity, sex and age.Methods:Data are from a population-based stroke surveillance study conducted in Nueces County, Texas, USA, a geographically isolated, bi-ethnic, urban community. Active (screening hospital admission logs, hospital wards, intensive care units) and passive (screening inpatient/ED discharge diagnosis codes) surveillance were used to identify cases aged ≥45 (n=4,874) validated by stroke physicians using a consistent stroke definition over time. Ischemic stroke rates were derived from Poisson regression using annual population counts from US Census to estimate at-risk population.Results:In those aged 45-59, rates increased in non-Hispanic Whites (104.3% relative increase; p<0.001) but decreased in Mexican Americans (-21.9%; p=0.03) such that rates were significantly higher in non-Hispanic Whites in 2016-2017 (p for ethnicity-time interaction<0.001). In those age 60-74, rates declined in both groups but more so in Mexican Americans (non-Hispanic Whites -18.2%, p=0.05; Mexican Americans -40.1%, p=0.002) resulting in similar rates for the two groups in 2016-2017 (p for ethnicity-time interaction=0.06). In those aged ≥75, trends did not vary by ethnicity, with declines noted in both groups (non-Hispanic Whites -33.7%, p=0.002; Mexican Americans -26.9%, p=0.02). Decreases in rates were observed in men (age 60-74 -25.7%, p=0.009; age ≥75 -39.2% p=0.002) and women (age 60-74 -34.3%, p=0.007; age ≥75 -24.0% p=0.02) in the two older age groups, while rates did not change in either sex in those age 45-59.Interpretation:Previously documented ethnic stroke incidence disparities have ended as a result of declining rates in Mexican Americans and increasing rates in non-Hispanic whites, most notably in midlife.

Rehabilitation Facilities

Background: Mexican Americans (MAs) have worse stroke outcomes than non-Hispanic whites (NHWs). One explanation may be ethnic differences in post-stroke rehabilitation; despite its effectiveness, non-clinical factors such as geographic availability may influence use of certain rehabilitation venues. We investigated ethnic differences in availability of stroke rehabilitation venues in a bi-ethnic community. Methods: Stroke survivors were identified through the population-based Brain Attack Surveillance in Corpus Christi (BASIC) Project from 2011-2013 in Nueces County, a bi-ethnic, mostly urban community in southeast Texas with a population of 340,000. Addresses of inpatient rehabilitation facilities (IRFs) and skilled nursing facilities (SNFs) providing stroke rehabilitation were identified by phone/internet and geocoded. Availability was defined as distance to and supply of each type of venue in relation to the survivor’s home. Supply was calculated as the count of each type of venue within a given radius (defined as the 90th percentile of distribution of distances to reflect a reasonable market area). Associations between availability and ethnicity were modeled using linear regression adjusted for census tract-level median household income, proportion <65 years, and population density as obtained from the 2012 American Community Survey. Results: A total of 942 survivors were eligible (62% MA, 38% NHW); 3 IRFs and 21 SNFs were identified. The average distances from the survivors’ homes to an IRF or SNF were 5 miles (SD=6) and 2 miles (SD=3), respectively. Supply was calculated within radii of 16 miles for IRFs and 4 miles for SNFs. The average count of rehabilitation venues within these radii was 2.6 IRFs (SD=0.9) and 7.9 SNFs (SD=4.7). There were no ethnic differences in the distance or supply of IRFs; however, MAs were on average 1 mile (CI:0.6-1.5) closer to and had 0.8 (CI:0.2,1.3) more SNFs within the radius than NHWs. Conclusions: Availability of rehabilitation venues was high for both ethnic groups; however, MAs have greater availability of SNFs compared to NHWs. Additional study is necessary to understand how the availability and quality of services within rehabilitation venues impact post-stroke rehabilitation among MA stroke survivors.

Introduction: Mexican Americans (MA) have worse cognitive outcomes following stroke relative to non-Hispanic whites (NHW). In a population-based study we examined whether MAs and NHWs have different cognition just after stroke (baseline) and different cognitive trajectories at 90 days post stroke. Methods: The sample included 598 participants from the Brain Attack Surveillance in Corpus Christi Project who had ischemic stroke between 2008-2013. Cognitive assessment was the 3MSE (English or Spanish). A change score was calculated (3MSE at 90 days minus 3MSE at baseline). Robust regression was used to examine ethnic differences in cognitive outcomes adjusted for sociodemographics, pre-stroke factors, and clinical stroke characteristics; missing covariate values were imputed with multiple imputation. Results: The sample was 57% MA, 35% NHW, and 8% other race/ethnicity. MAs were younger, had lower educational attainment, and were less likely to have health insurance than NHWs (all p<0.01). MAs showed lower cognitive function at baseline (Table 1) and less cognitive recovery 90 days following stroke compared with NHWs (Table 2), which remained significant after accounting for all covariates (Model 5, Tables 1 and 2). Conclusions: MAs have worse post-stroke baseline cognition and less robust cognitive recovery 90 days following stroke than NHWs. This disparity should be addressed through rehabilitation or other interventions.

Background: Mexican Americans (MAs) have worse neurologic, functional and cognitive outcomes after stroke than non Hispanic whites (NHWs). Stroke rehabilitation is important for outcome. In a population-based study, we sought to determine if allocation of stroke rehabilitation services differed by ethnicity. Methods: Consecutive stroke patients were identified for a three month time period as part of the Brain Attack Surveillance in Corpus Christi (BASIC) project, Texas, USA. Cases were validated by physicians using source documentation. Patients were followed prospectively for three months following stroke to determine self-reported rehabilitation services. Descriptive statistics were used to describe the study population. Ethnic comparisons of rehabilitation services were made using chi-squared or Fisher’s exact tests. Results: Seventy-two subjects (50 MA, 22 NHW) were followed. Mean age, NHW-69 (sd-13), MA-66 (sd-11) years, sex (NHW 55% male, MA 50% male) and median presenting NIHSS (NHW-2.5, MA-3.0) did not differ significantly. There were no ethnic differences in the proportion of patients who were discharged home without rehabilitation services (p=0.9). Among those who received rehabilitation (n=48), the figure shows the distribution of the first place for services. NHWs were more likely to be discharged to inpatient rehabilitation (73%) compared with MAs (30%), p=0.016. MAs (51%) were much more likely to be receive home rehabilitation services compared with NHWs (0%) (p=0.0017). Conclusions: In this population-based study, MAs were more likely to receive home-based rehabilitation while NHWs more likely to get inpatient rehabilitation. This disparity may, in part, explain the worse stroke outcome in MAs.

Background and Purpose: Informal (unpaid) caregiving usually provided by family is important poststroke. We studied whether the prevalence of informal caregiving after stroke differs between Mexican Americans (MAs) and non-Hispanic Whites (NHWs). Methods: Between October 2014 and December 2018, participants in the BASIC (Brain Attack Surveillance in Corpus Christi) project in Nueces County, Texas, were interviewed 90 days after stroke to determine which activities of daily living they required help with and whether family provided informal caregiving. Ethnic differences between MAs and NHWs were determined by logistic regression. The logistic models were stratified by formal (paid) care status. Odds ratios (95% CIs) are reported with NHW as the referent group. Fisher exact tests were used to assess the association of ethnicity with relationship of caregiver and with individual activities of daily living. Results: Eight hundred thirty-one patients answered the caregiving questions. Of these, 242 (29%) received family caregiving (33% of MAs and 23% of NHWs), and 142 (17%) received paid caregiving (21% of MAs and 10% of NHWs). There were no ethnic differences in stroke severity. In logistic regression analyses, among those without formal, paid care, MAs were more likely to have informal caregiving (odds ratio, 1.75 [95% CI, 1.12–2.73]) adjusted for age, National Institutes of Health Stroke Scale, prestroke modified Rankin Scale, and insurance. No ethnic differences in informal care were found among those who had formal care. There were no differences between ethnic groups in which family members provided the informal care. MAs were more likely to require help compared with NHWs for walking ( P <0.0001), bathing ( P <0.0001), hygiene ( P =0.0012), eating ( P =0.0004), dressing ( P <0.0001), ambulating ( P =0.0304), and toileting ( P =0.0003). Conclusions: MAs required more help poststroke than NHWs for assistance with activities of daily living. MAs received more help for activities of daily living through informal, unpaid caregiving than NHWs if they were not also receiving formal, paid care. Efforts to help minority and low-resource populations provide stroke care are needed.

Low Trauma Fracture

Background: Risk for low trauma fracture is increased by >30% after ischemic stroke. Additionally, in the IRIS trial pioglitazone therapy prevented ischemic stroke but increased fracture risk. We derived a risk score to predict risk of fracture one year after ischemic stroke. Methods: The Fracture Risk after Ischemic Stroke (FRAC-Stroke) Score was derived in 20,435 ischemic stroke patients from the Ontario Stroke Registry discharged from 2003-2012, using Fine-Gray competing risk regression. Candidate variables were medical conditions included in the validated World Health Organization FRAX risk score complemented by variables related to stroke severity. Registry patients were linked to population-based Ontario health administrative data to identify low trauma fractures (defined as any fracture of the femur, forearm, humerus, pelvis or vertebrae, excluding fractures resulting from trauma, motor vehicle accidents, falls from a height or in people with active cancer). The score was externally validated in 13,698 other ischemic stroke patients in the population-based Ontario stroke audit (2002-2012). Results: Mean age was 72; 42% were women. Low trauma fracture occurred within 1 year of discharge in 741/20435 (3.6%); cumulative incidence increased linearly throughout follow-up. Age, discharge modified Rankin score (mRS), and history of arthritis, osteoporosis, falls and previous fracture contributed significantly to the model. Model discrimination was good (c statistic 0.72). Including discharge mRS significantly improved discrimination (relative integrated discrimination index 8.7%). Fracture risk was highest in patients with mRS 3 and 4 but lowest in bedbound patients (mRS 5). From the lowest to the highest FRAC-Stroke quintile the cumulative incidence of 1-year low trauma fracture increased from 1% to 9%. Predicted and observed rates of fracture were similar in the external validation cohort. Conclusion: The FRAC-Stroke score allows the clinician to identify ischemic stroke patients at higher risk of low trauma fracture within one year. This information might be used to target patients for early bone densitometry screening to diagnose and manage osteoporosis, and to estimate baseline risk prior to starting pioglitazone therapy.

Disordered Breathing

Background: Sleep-disordered breathing (SDB) is an independent risk factor for stroke. The reported prevalence of SDB after stroke ranges from 60 to >70%, while the pre-stroke prevalence of SDB is less well described. Moreover, much of these data are derived from ischemic stroke or mixed ischemic stroke and intracerebral hemorrhage (ICH) cohorts. Studies that assess the prevalence of SDB before and after ICH are lacking, with only one prior study (n=32) that reported a post-ICH SDB prevalence of 78%. We report herein the results of a second, larger, prospective study that assessed the prevalence of pre- and post-ICH. Methods: Participants enrolled in the population-based stroke surveillance study, the Brain Attack Surveillance in Corpus Christi (BASIC) project, with ICH from 2010-2015 were screened for SDB with the well validated ApneaLink Plus portable monitor (SDB defined as apnea-hypopnea index (AHI) ≥10). The Berlin questionnaire was administered, with reference to the pre-ICH state, to assess for possible pre-stroke SDB. Results: Of the 60 ICH participants screened, the median age was 63 years (interquartile range (IQR): 55.5, 74.5). Twenty-one (35%) were female, 54 (90%) were Mexican American, and 53 (88%) had a history of hypertension. The median Glasgow Coma Scale score was 15.0 (IQR: 15.0, 15.0) and the median NIHSS was 5.5 (IQR: 1.5, 8.0). Post-ICH, the median AHI was 9.5 (IQR: 5.5, 19.0); almost half (46.7%) met criteria for SDB. Thirty-four participants (56.7%) screened as high risk for SDB pre-ICH. Conclusion: Sleep-disordered breathing was highly prevalent after ICH, and also likely common before ICH, in this mostly Mexican American, community-based sample. If SDB increases risk for ICH, the findings suggest a potential new treatment target to prevent ICH and recurrent ICH.
