Neuropsychological assessment of mild cognitive impairment in Latinx adults: A scoping review.

Latinx populations are rapidly growing and aging in the United States. There is a critical need to accurately and efficiently detect those at risk for dementia, particularly those with mild cognitive impairment (MCI). MCI diagnosis often relies on neuropsychological assessment, although cultural, demographic, and linguistic characteristics may impact test scores.

Time Trends in Race-Ethnic Differences in Do-Not-Resuscitate Orders After Stroke.

Background and Purpose- Do-not-resuscitate (DNR) orders are common after stroke, though there are limited data on trends over time. We investigated time trends in DNR orders in a community with a large minority population. Methods- Cases of ischemic stroke (IS) or intracerebral hemorrhage (ICH) were identified from the BASIC study (Brain Attack Surveillance in Corpus Christi) from June 2007 through October 2016.

A Population-Based Study of Intracerebral Hemorrhage Survivors' Outcomes.

Background: We evaluated 3-month neurologic, functional, cognitive, and quality of life (QOL) outcomes in intracerebral hemorrhage (ICH) overall, and by sex and ethnicity in a population-based study.

Methods: Spontaneous ICH patients were identified from the Brain Attack Surveillance in Corpus Christi project (November 2008 to December 2013). Outcomes included neurologic (National Institutes of Health Stroke Scale: range 0-42), functional (activities of daily living/instrumental activities of daily living score: range 1-4, higher worse), cognitive (Modified Mini-Mental State Examination [3MSE]: range 0-100), and QOL (short-form stroke-specific QOL scale: range 0-5, higher better).

Intracerebral hemorrhage and sleep-disordered breathing.

Objective/background: Limited data are available on sleep-disordered breathing (SDB) following intracerebral hemorrhage (ICH). Our aim was to characterize the objective measures of post-ICH SDB and questionnaire-reported pre-ICH sleep characteristics, overall and by ethnicity.

Patients/methods: Participants with ICH who were enrolled in the population-based Brain Attack Surveillance in Corpus Christi project (2010-2016) reported their pre-ICH sleep duration and completed the Berlin Questionnaire to characterize pre-ICH risk of SDB.

Lack of Worsening of Sleep-Disordered Breathing After Recurrent Stroke in the BASIC Project.

Study Objectives: To investigate the difference in sleep-disordered breathing (SDB) prevalence and severity after an index and recurrent stroke.

Methods: In a sample of 40 subjects, home sleep apnea tests were performed a median of 10 days after an index ischemic stroke and 14 days after a recurrent ischemic stroke. A respiratory event index (REI) of ≥ 10 events/h (apneas plus hypopneas per hour of recording) was used to define clinically significant SDB.

Wake-up stroke is not associated with sleep-disordered breathing in women.

Background: We sought to investigate the frequency of wake-up stroke (WUS) and its association with sleep-disordered breathing (SDB) in women.

Methods: Within a population-based study, women with acute ischemic stroke were asked about their stroke symptom onset time. SDB screening was performed with the well-validated ApneaLink Plus device; SDB was defined by a respiratory event index ≥10.

Sex differences in sleep-disordered breathing after stroke: results from the BASIC project.

Objective/background: Sleep-disordered breathing (SDB), an independent risk factor for stroke, is associated with worse post-stroke outcomes. Differences in the relationship between SDB and stroke may exist for women versus men. In this population-based study, we compared the prevalence of both pre- and post-stroke SDB by sex.

Stroke Quality Measures in Mexican Americans and Non-Hispanic Whites.

Mexican Americans (MAs) have been shown to have worse outcomes after stroke than non-Hispanic Whites (NHWs), but it is unknown if ethnic differences in stroke quality of care may contribute to these worse outcomes. We investigated ethnic differences in the quality of inpatient stroke care between MAs and NHWs within the population-based prospective Brain Attack Surveillance in Corpus Christi (BASIC) Project (February 2009- June 2012). Quality measures for inpatient stroke care, based on the 2008 Joint Commission Primary Stroke Center definitions were assessed from the medical record by a trained abstractor.

Stroke Performance Measures Do Not Predict Functional Outcome.

Background And Purpose: Poststroke functional outcome is critical to stroke survivors. We sought to determine whether adherence to current stroke performance measures is associated with better functional outcome 90 days after an ischemic stroke.

Methods: Utilizing the Brain Attack Surveillance in Corpus Christi cohort, we examined adherence to 7 ischemic stroke performance measures from February 2009 to June 2012.

Sex Disparity in Stroke Quality of Care in a Community-Based Study.

Background: Studies have suggested that women may receive lower stroke quality of care (QOC) than men, although population-based studies at nonacademic centers are limited. We investigated sex disparities in stroke QOC in the Brain Attack Surveillance in Corpus Christi Project.

Methods: All ischemic stroke patients admitted to 1 of 6 Nueces County nonacademic hospitals between February 2009 and June 2012 were prospectively identified.

Ischemic stroke subtype and presence of sleep-disordered breathing: the BASIC sleep apnea study.

Background: Little is known about the prevalence of sleep-disordered breathing (SDB) across ischemic stroke subtypes. Given the important implications for SDB screening, we tested the association between SDB and ischemic stroke subtype in a population-based study.

Methods: Within the Brain Attack Surveillance in Corpus Christi Project, ischemic stroke patients were offered SDB screening with the ApneaLink Plus (n = 355).

Prevalence of pre-stroke sleep apnea risk and short or long sleep duration in a bi-ethnic stroke population.

Background: The ethnic disparity in ischemic stroke between Mexican Americans (MAs) and non-Hispanic whites (NHWs) may be partly attributable to disparities in sleep and its disorders. We therefore assessed whether pre-stroke sleep apnea symptoms (SA risk) and pre-stroke sleep duration differed between MAs and NHWs.

Methods: MA and NHW ischemic stroke survivors in the Brain Attack Surveillance in Corpus Christi (BASIC) project reported sleep duration and SA symptoms on the validated Berlin questionnaire, both with respect to their pre-stroke baseline.

Brainstem infarction and sleep-disordered breathing in the BASIC sleep apnea study.

Background: Association between cerebral infarction site and poststroke sleep-disordered breathing (SDB) has important implications for SDB screening and the pathophysiology of poststroke SDB. Within a large, population-based study, we assessed whether brainstem infarction location is associated with SDB presence and severity.

Methods: Cross-sectional study was conducted on ischemic stroke patients in the Brain Attack Surveillance in Corpus Christi (BASIC) project.

Intracerebral hemorrhage mortality is not changing despite declining incidence.

Objective: To determine trends in incidence and mortality of intracerebral hemorrhage (ICH) in a rigorous population-based study.

Methods: We identified all cases of spontaneous ICH in a South Texas community from 2000 to 2010 using rigorous case ascertainment methods within the Brain Attack Surveillance in Corpus Christi Project. Yearly population counts were determined from the US Census, and deaths were determined from state and national databases.

Is technologist review of raw data necessary after home studies for sleep apnea?

Study Objectives: As the importance of portable monitors for detection of sleep apnea increases, efficient and cost-minimizing methods for data interpretation are needed. We sought to compare in stroke patients, for whom portable studies often have particular advantages, results from a cardiopulmonary monitoring device with and without manual edits by a polysomnographic technologist.

Methods: Participants in an ongoing stroke surveillance study in Corpus Christi, Texas, underwent sleep apnea assessments with the ApneaLink Plus device within 45 days of stroke onset.

Validation of the 12-item stroke-specific quality of life scale in a biethnic stroke population.

The 12-item Stroke-Specific Quality of Life Scale (SSQOL), a shortened version of the original SSQOL, was developed to be an efficient and valid outcome in stroke research. We aimed to assess the validity of this scale in a biethnic ischemic stroke population. Patients with validated ischemic stroke who completed the original 49-item SSQOL at 90 days poststroke were identified from a population-based study, the Brain Attack Surveillance in Corpus Christi Project.

A population-based analysis of ethnic differences in admission to the intensive care unit after stroke.

Background: Mexican-Americans (MAs) have shown lower post-stroke mortality compared to non-hispanic whites (NHWs). Limited evidence suggests race/ethnic differences exist in intensive care unit (ICU) admissions following stroke. Our objective was to investigate the association of ethnicity with admission to the ICU following stroke.

Computed tomography findings for intracerebral hemorrhage have little incremental impact on post-stroke mortality prediction model performance.

Background: Stroke outcome studies often combine cases of intracerebral hemorrhage (ICH) and ischemic stroke (IS). These studies of mixed stroke typically ignore computed tomography (CT) findings for ICH cases, though the impact of omitting these traditional predictors of ICH mortality is unknown. We investigated the incremental impact of ICH CT findings on mortality prediction model performance.

The prevalence of spirituality, optimism, depression, and fatalism in a bi-ethnic stroke population.

To provide insight into the reduced post-stroke all-cause mortality among Mexican Americans, we explored ethnic differences in the pre-stroke prevalence of (1) spirituality, (2) optimism, (3) depression, and (4) fatalism in a Mexican American and non-Hispanic white stroke population. The Brain Attack Surveillance in Corpus Christi (BASIC) project is a population-based stroke surveillance study in Nueces County, Texas. Seven hundred ten stroke patients were queried.

Mexican Americans with atrial fibrillation have more recurrent strokes than do non-Hispanic whites.

Background And Purpose: Atrial fibrillation is a common cause of stroke with a known preventive treatment. We compared poststroke recurrence and survival in Mexican Americans (MAs) and non-Hispanic whites (NHWs) with atrial fibrillation in a population-based study.

Methods: Using surveillance methods from the Brain Attack Surveillance in Corpus Christi Project, cases of ischemic stroke/transient ischemic attack with atrial fibrillation were prospectively identified from January 2000 to June 2008.

Validity of proxies and correction for proxy use when evaluating social determinants of health in stroke patients.

Background And Purpose: The purpose of this study was to evaluate stroke patient-proxy agreement with respect to social determinants of health, including depression, optimism, and spirituality, and to explore approaches to minimize proxy-introduced bias.

Methods: Stroke patient-proxy pairs from the Brain Attack Surveillance in Corpus Christi Project were interviewed (n=34). Evaluation of agreement between patient-proxy pairs included calculation of intraclass correlation coefficients, linear regression models (ProxyResponse=alpha(0)+alpha(1)PatientResponse+delta, where alpha(0)=0 and alpha(1)=1 denotes no bias) and kappa statistics.

Ethnic differences in do-not-resuscitate orders after intracerebral hemorrhage.

Objective: To explore ethnic differences in do-not-resuscitate orders after intracerebral hemorrhage.

Design: Population-based surveillance.

Setting: Corpus Christi, Texas.

Stroke health and risk education (SHARE) pilot project: feasibility and need for church-based stroke health promotion in a bi-ethnic community.

Background And Purpose: We performed a pilot project to assess the need for and feasibility of a church-based stroke risk reduction intervention in a predominantly Mexican American community.

Methods: Participants were recruited after each mass on a single weekend from 2 Catholic churches in Corpus Christi, Texas. Questionnaires about personal stroke risk factors and interest in program participation were completed, and blood pressure screening was performed.

Screening for myocardial infarction and ischemic stroke: a population-based study.

Studies that accurately identify myocardial infarction (MI) and stroke within populations would provide valuable epidemiological information as well as data on vascular disease prevention. We performed a pilot study to assess the feasibility of adding MI surveillance to an ongoing population-based stroke surveillance study, the Brain Attack Surveillance in Corpus Christi (BASIC) Project. We also tested two screening methods for MI ascertainment: discharge International Classification of Diseases, Ninth Revision (ICD-9) codes and cardiac biomarker screening.

Defining cause of death in stroke patients: The Brain Attack Surveillance in Corpus Christi Project.

Stroke mortality is an important national health statistic and represents a frequent endpoint for epidemiologic studies. Several methods have been used to determine cause of death after stroke, but their agreement and reliability are unknown. Two hundred consecutive deaths of transient ischemic attack or ischemic stroke patients were identified (January 2000-September 2001) from an ongoing population-based stroke surveillance study in Texas, The Brain Attack Surveillance in Corpus Christi Project.
