Allostatic load and cognitive recall among young adults: Racial, ethnic, and sex-specific variations.

INTRODUCTION: While factors such as age and education have been associated with persistent differences in functional cognitive decline, they do not fully explain observed variations particularly those between different racial/ethnic and sex groups. The aim of this study was to explore the association between allostatic load (AL) and cognition in a racially diverse cohort of young adults. METHODS: Utilizing Wave V of the National Longitudinal Study of Adolescent to Adult Health - a nationally representative, longitudinal survey of adults aged 34-44, this study utilized primary data from 10 immune, cardiovascular, and metabolic biomarkers to derive an AL Index. Cognition was previously recorded through word and number recall scores. Regression analysis evaluated the association between cognitive recall, AL, age, sex, and race/ethnicity. RESULTS: Regression results indicated statistically higher AL scores among Blacks (IRR = 1.09, CI = 1.01, 1.19) compared to Whites and lower AL score among females compared to males (IRR = 0.76, CI = 0.72, 0.81). At zero AL, Blacks (IRR = 1.2399, CI = 1.2398, 1.24) and Other races (IRR = 1.4523, CI = 1.452, 1.4525) had higher recall while Hispanics (IRR = 0.808, CI = 0.8079, 0.8081) had lower recall compared to Whites. Relative to males, females had higher number recall (IRR = 1.1976, CI = 1.1976, 1.1977). However, at higher, positive levels of AL, Blacks (IRR = 0.9554, CI = 0.9553, 0.9554), Other races (IRR = 0.9479, CI = 0.9479, 0.9479) and females (IRR = 0.9655, CI = 0.9655, 0.9655) had significantly lower number recall than Whites and males respectively. CONCLUSIONS: Race and sex differences were observed in recall at different levels of AL. Findings demonstrate the need for further exploration of cognition in young adults across diverse populations that includes examination of AL.

The Intersection of Social Determinants of Health and Post-stroke Aphasia Outcomes: A Need for Intersectional Analysis.

Aphasia is a disorder that results from damage to portions of the brain that are responsible for language and can vary significantly by type and severity. Differences in aphasia outcomes are influenced by the social determinants of health (SDOH). The SDOH are structural, environmental, and personal determinants that influence health outcomes. Intersectionality, or how one's social and political identities interact to influence individual life outcomes and/or advantage in our society, provides a way to examine the varying levels of the SDOH. However, intersectionality is complex, difficult to measure, and has not yet been explored in post-stroke aphasia outcomes. This article reviews the relationship of race and aphasia outcomes and the SDOH and aphasia outcomes. Additionally, we provide a novel current approach to examine the SDOH and aphasia outcomes. Lastly, we discuss the need for evaluation of intersectionality in aphasia and aim to provide a leveled social-ecological framework to examine aphasia-related outcomes. With notable individual differences among aphasia outcomes, we present a framework to support optimizing research and clinical aphasia care in speech-language pathology.

Healthcare cost and race: analysis of young women with stroke.

BACKGROUND: Over the last decade, the prevalence of young stroke has increased 40% particularly among vulnerable populations. These strokes are often more severe with worse outcomes. However, few studies have examined the impact on annual healthcare costs. METHODS: Data from the 2008 to 2018 Medical Expenditure Panel Survey (MEPS) was used to identify a sample of female stroke survivors aged 18 and 60. MEPS includes demographics, health status, healthcare use, and expenditures for all participants providing the largest nationally representative data source of healthcare costs in the US. First, differences in racial and ethnic healthcare expenditure among young women with stroke were evaluated controlling for insurance type and demographic characteristics. Second, the relationship between healthcare expenditure and 1) time post stroke, 2) comorbidities, 3) healthcare utilization, and 4) post-stroke functional status was assessed. Finally, differential healthcare quality was tested as a potential mitigating differential. RESULTS: Young Black women with stroke spend roughly 20% more on healthcare than White women after controlling for insurance, time post-stroke, healthcare utilization, and demographic differences. Costs remain 17% higher after controlling for comorbidities. Differences in expenditure are larger if survivors have diabetes, high blood pressure, or high cholesterol (78%, 24%, and 28%, respectively). Higher expenditure could not be explained by higher healthcare utilization, but lower quality of healthcare may explain part of the differential. CONCLUSION: Young Black women with stroke have 20% greater healthcare expenditure than other groups. Cost differentials cannot be explained by differentials in comorbidities, utilization, time post stroke, or functionality. Additional research is needed to explain these differences.

Early Nutrition among Infants Admitted to the NICU with Cleft Lip and Palate.

OBJECTIVE: The objective of this study was to examine differences in human milk feeding outcomes among infants admitted to a neonatal intensive care unit (NICU) with and without cleft lip and palate (CLP). METHOD: Data were used from a sample of infants admitted to the NICU with and without CLP from the 2018 National Vital Statistics System. For baseline comparisons, Chi-square tests of independence were used to compare categorical variables, and independent samples t tests were used for continuous variables. Logistic regression models were performed to determine the odds of human milk feeding at discharge in infants admitted to the NICU with CLP. RESULTS: The total sample included 345,429 infants admitted to the NICU, of which 660 had CLP. Significant differences were found among the following variables when baseline comparisons were made between infants admitted to the NICU with and without CLP: mother's race, mother's education, maternal smoking record, childbirth delivery method, presence of maternal pre-pregnancy diabetes, five-minute APGAR score, multiparity record (having more than one baby at birth), gestational age, and gestational weight. After controlling for baseline differences, results indicated reduced odds of human milk feeding at discharge in infants admitted to the NICU with CLP compared to those without CLP (OR = .543; 95% CI.455,.648). CONCLUSION: Results suggest reduced odds of human milk feeding at discharge among infants admitted to the NICU with CLP compared to those without CLP. These findings emphasize the necessity of awareness and facilitation of human milk feeding in this population.

Health, economic and social disparities among transgender women, transgender men and transgender nonbinary adults: Results from a population-based study.

We investigated health, economic, and social disparities among transgender adults (transgender women, men, and nonbinary) aged 18 years and older. Using population-based data from the Washington State Behavioral Risk Factor Surveillance System (WA-BRFSS), we pooled 2016 through 2019 data (n = 47,894). We estimated weighted distributions and prevalence by gender identity for background characteristics, economic, social and health indicators. We performed regressions of these indicators on gender identity, including transgender versus cisgender adults and transgender nonbinary adults compared to cisgender adults, followed by subgroup analyses: transgender women and men compared to each cisgender group and to one another, adjusting for covariates. Compared to cisgender adults, transgender adults overall were significantly younger and lower income with less education; more likely single with fewer children; and had several elevated health risks, including poor physical and mental health, and higher rates of chronic conditions and disability. Alternatively, transgender men and women had higher rates of flu vaccination than cisgender men. Between transgender subgroups, transgender men and transgender nonbinary adults were younger than transgender women; transgender men were significantly less likely married or partnered than transgender women; and, transgender women were more likely to live alone than nonbinary respondents. This is one of the first population-based studies to examine both between and within subgroup disparities among cisgender, transgender binary, and transgender nonbinary adults, revealing patterns of inequities across subgroups. More research understanding the mechanisms of these disparities and the development of targeted interventions is needed to address the unique needs of subgroups of transgender people.

Epicardial adipose tissue volume is greater in men with severe psoriasis, implying an increased cardiovascular disease risk: A cross-sectional study.

BACKGROUND: Patients with psoriasis have elevated risk of coronary artery disease. OBJECTIVE: Do patients with severe psoriasis have larger epicardial adipose tissue volumes (EAT-V) that are associated with cardiovascular risk? METHODS: For this cross-sectional study, we recruited dermatology patients with severe psoriasis and control patients without psoriasis or rheumatologic disease themselves or in a first-degree relative. Participants aged 34 to 55 years without known coronary artery disease or diabetes mellitus underwent computed tomography (CT); EAT-V was obtained from noncontrast CT heart images. RESULTS: Twenty-five patients with psoriasis (14 men, 11 women) and 16 controls (5 men, 11 women) participated. Groups had no statistical difference in age, body mass index, various cardiovascular risk factors (except high-sensitivity C-reactive protein in men), CT-determined coronary artery calcium scores or plaque, or family history of premature cardiovascular disease. Mean EAT-V was greater in the psoriasis group compared to controls (P = .04). There was no statistically significant difference among women; however, male patients with psoriasis had significantly higher EAT-V than controls (P = .03), even when corrected for elevated high-sensitivity C-reactive protein (P = .05). LIMITATIONS: A single-center convenience sample may not be representative. CONCLUSION: Males with psoriasis without known coronary disease or diabetes had greater EAT-V than controls. EAT-V may be an early identifier of those at increased risk for cardiovascular events.

A Preliminary Study of Anatomical Changes Following the Use of a Pedicled Buccal Fat Pad Flap During Primary Palatoplasty.

OBJECTIVE: The purpose of this study was to examine the surgical impact of the pedicled buccal fat pad (BFP) flap on the levator veli palatini (LVP) muscle and surrounding velopharyngeal (VP) anatomy following primary palatoplasty using magnetic resonance imaging (MRI). DESIGN: Observational, prospective. SETTING: MRI studies were completed at 3 different facilities. All participants with BFP flap were operated on by the same surgeon. PARTICIPANTS: Five pediatric participants with cleft palate with or without cleft lip (CP±L) who underwent primary palatoplasty with BFP flap placement. Comparison groups consisted of 10 participants: 5 with CP±L who did not receive the BFP flap and 5 healthy controls. INTERVENTIONS: All participants underwent nonsedated MRI 2 to 5 years postoperatively. MAIN OUTCOMES AND MEASURES: Anatomical measures of the velopharynx and LVP among the 3 participant groups. RESULTS: Median values were significantly different among groups for velar length (P = .042), effective velar length (P = .048), effective VP ratio (P = .046), LVP length (P = .021), extravelar LVP length (P = .009), and LVP origin-origin distance (P = .030). Post hoc analysis revealed a statistically significant difference between the BFP and traditional repair groups for effective VP ratio (P = .040), extravelar LVP length (P = .033), and LVP length (P = .022). CONCLUSIONS: This study provides preliminary support that the BFP flap creates a longer velum, with increased distance between the posterior hard palate and the LVP, and a larger effective VP ratio compared to traditional surgical techniques. Future research is needed to determine whether this procedure provides a more favorable mechanism for VP closure.

Understanding the Economics of Aphasia: Recent Findings from Speech and Language Research.

In recent years, stakeholders engaged in the study, treatment, and understanding of aphasia outcomes have emphasized the need for greater transparency regarding the economics of aphasia rehabilitation. Most notably, third-party payers and clinicians have a keen interest in understanding the resources used to treat aphasia, particularly the cost-effectiveness and value of aphasia treatments. In this article, we review the current literature related to the economic burden of aphasia and the cost and cost-effectiveness of aphasia treatments. To date, relatively few scholars have attempted to study the efficiency, scale, and scope related to the economics of aphasia and the cost-effectiveness of aphasia treatment. While studies of the cost-effectiveness of aphasia treatments have shown rehabilitative treatments conform to established quality and cost benchmarks, the continued progress and developments in the treatment of aphasia and measurement of clinical outcomes has left many areas unstudied. We highlight the need for greater emphasis on the cost-effectiveness of aphasia treatments in addition to the traditional focus on the efficacy of treatment outcomes.

Heterogeneity among women with stroke: health, demographic and healthcare utilization differentials.

BACKGROUND: Although age specific stroke rates are higher in men, women have a higher lifetime risk and are more likely to die from a stroke. Despite this increased severity, most studies focus on male/female differences in stroke onset, patterns of care and stroke-related outcomes. Given that stroke presents differently in men and women, mixed sex studies fail to fully capture heterogeneity among women with stroke and the subsequent impact on their outcomes. This study examined the sociodemographic characteristics, factors related to stroke incidence and post-stroke functional status between young (< 60) and old (≥ 60) women with stroke. METHODS: Using 5 years of data from the National Health Interview Survey (NHIS), a nationally representative sample of US adults, cohorts of young and old women with stroke were identified. A set of demographic/lifestyle, health services utilization and health status characteristics were used evaluate within gender heterogeneity in three ways. First, disparities in population characteristics were assessed using Chi-Square and t tests. Second, young and old women with stroke were matched with women without stroke in their respective cohorts to determine differences in factors related to stroke incidence. Finally, the determinants of post-stroke functional limitation for the two cohorts were determined. RESULTS: Young women with stroke were more likely to be Black, smoke regularly and frequently consume alcohol than older women. Young women were also less likely to engage with their health provider regularly or receive preventative health screenings. Diabetes, high blood pressure, high cholesterol and high BMI were correlated with an increased relative likelihood of stroke among older women. In contrast, family size, smoking frequency, alcohol consumption and sleep were correlated with an increased prevalence of stroke among young women. Although factors correlated with stroke varied between young and old women, health status and receipt of healthcare were the most significant determinants of post-stroke functional status for both cohorts. CONCLUSIONS: Health related characteristics were the primary correlates of stroke in older women, whereas post-stroke lifestyle and behaviors are the most significant correlates for younger stroke survivors. These findings suggest that while receipt of health services is essential for preventing stroke in both young and old women, providers should stress the importance of post-stoke lifestyle and behaviors to younger women at risk of stroke using approaches that may be different from older stroke women.

Evaluation of the Symmetry of the Levator Veli Palatini Muscle and Velopharyngeal Closure Among a Noncleft Adult Population.

PURPOSE: The goal of this study is to determine the typical range of asymmetry between the length and thickness of the levator veli palatini muscle and to explore the impact of the observed asymmetry on velopharyngeal closure. A second objective is to report normative length and thickness of the levator veli palatini muscle among adults with typical velopharyngeal anatomy. METHOD: Magnetic resonance imaging (MRI) data and Amira 5.5 Visualization software were used to evaluate the levator veli palatini muscle among 89 participants with typical velopharyngeal anatomy. Flexible nasopharyngoscopy was used to determine the function of velopharyngeal closure among 39 of the 89 participants with typical velopharyngeal anatomy to examine the functional impact of observed asymmetry. RESULTS: Matched paired t tests demonstrated a nonsignificant difference between the length and thickness of the right and left levator muscle. The mean difference between the right and left length of the levator muscle was 2.28 mm but ranged from 0.09 mm to 10.37 mm. In all cases where individuals displayed asymmetry in the levator muscle through MRI, there was no observed impact on the symmetry of velopharyngeal closure. DISCUSSION: This study suggest that differences in the right and left levator veli palatini muscle are not significant among individuals without cleft palate. However, among individual cases where asymmetry was sizeable, there was no direct impact on the closure pattern. This may suggest there are multiple factors that contribute to asymmetrical velopharyngeal closure that are beyond the level of the levator veli palatini muscle.

Quantifying Experiences with Telepractice for Aphasia Therapy: A Text Mining Analysis of Client Response Data.

Measures of satisfaction following treatment for aphasia have been limited. The challenge associated with reduced verbal output among many persons with aphasia (PWA) has reportedly been a key reason measures of treatment satisfaction have been limited. A novel approach to measure treatment satisfaction is the use of content analysis (CA), which uses the presence of certain words, themes, or concepts to explore outcomes such as treatment satisfaction particularly among individuals who generate limited output. CA utilizes responses and response patterns to assign meaning to client responses. The aim of this study was to use CA to measure posttreatment satisfaction with a telepractice approach for aphasia treatment. Seventeen PWA received 12 treatment sessions over a 6-week period. At the conclusion of the treatment, CA was utilized to explore patient satisfaction with this treatment approach. The participants reported an overall positive sentiment for the telepractice approach. Two primary topics emerged which were healthcare provider and healthcare delivery, where text analysis revealed discussion of these topics to be centered around being "helpful" and "being effective." This study demonstrated that CA can be an effective approach for determining satisfaction with aphasia treatment particularly among PWA with limited verbal abilities.

Urban-Rural Differences in Service Utilization and Costs of Care for Racial-Ethnic Groups Hospitalized With Poststroke Aphasia.

OBJECTIVE: Although residence is a key contributor to cost and utilization in stroke patient care, its contribution to the care of persons with aphasia (PWA) is unknown. The objective of this study was to use discharge-level hospital inpatient data to examine the influence of patient residence (rural vs urban) and race-ethnicity on service utilization and cost of care among PWA. DESIGN: Cross-sectional. SETTING: Administrative data from acute care hospitals in the state of North Carolina. PARTICIPANTS: Individuals (N=4381) with poststroke aphasia. INTERVENTIONS: N/A. MAIN OUTCOME MEASURES: Length of stay (LOS), speech-language pathology (SLP) service utilization, costs of care. METHODS: The 2011-2012 Healthcare Cost and Utilization Project State Inpatient Database data were analyzed to examine the effect of rural or urban residence on LOS, SLP service utilization, as well as total inpatient and SLP service costs. These outcomes were further analyzed across both residence and racial groups (non-Hispanic white and non-Hispanic black). Outcomes were analyzed using generalized linear model. RESULTS: Both rural and urban black PWA experienced longer average LOS after controlling for demographics, illness severity, and the hospital where they received care. Rural blacks experienced longer LOS, received greater SLP services, and incurred greater average total hospital costs than their rural white counterparts after adjusting for differences in their demographics and stroke or illness severity. The differences were attenuated after controlling for the hospital where they received care. CONCLUSIONS: For PWA, race-ethnicity has a larger effect on average total medical costs, SLP service utilization, and LOS than residence. It is unclear how and why blacks with aphasia have greater service utilization and costs in acute care, yet their aphasia outcomes are worse. Future studies are required to explore potential factors such as quality of care.

Metabolic Effects of Diet and Exercise in Patients with Moderate to Severe CKD: A Randomized Clinical Trial.

CKD is steadily increasing along with obesity worldwide. Furthermore, obesity is a proinflammatory risk factor for progression of CKD and cardiovascular disease. We tested the hypothesis that implementation of caloric restriction and aerobic exercise is feasible and can improve the proinflammatory metabolic milieu in patients with moderate to severe CKD through a pilot, randomized, 2×2 factorial design trial. Of 122 participants consented, 111 were randomized to receive caloric restriction and aerobic exercise, caloric restriction alone, aerobic exercise alone, or usual care. Of those randomized, 42% were women, 25% were diabetic, and 91% were hypertensive; 104 started intervention, and 92 completed the 4-month study. Primary outcomes were a change from baseline in absolute fat mass, body weight, plasma F2-isoprostane concentrations, and peak oxygen uptake (VO2 peak). Compared with usual care, the combined intervention led to statistically significant decreases in body weight and body fat percentage. Caloric restriction alone also led to significant decreases in these measures, but aerobic exercise alone did not. The combined intervention and each independent intervention also led to significant decreases in F2-isoprostane and IL-6 concentrations. No intervention produced significant changes in VO2 peak, kidney function, or urine albumin-to-creatinine ratio. In conclusion, 4-month dietary calorie restriction and aerobic exercise had significant, albeit clinically modest, benefits on body weight, fat mass, and markers of oxidative stress and inflammatory response in patients with moderate to severe CKD. These results suggest healthy lifestyle interventions as a nonpharmacologic strategy to improve markers of metabolic health in these patients.

Gender differences in aphasia outcomes: evidence from the AphasiaBank.

BACKGROUND: Stroke is one of the leading causes of death in the United States. Aphasia is a language impairment which results as a consequence of stroke. Gender differences are reported in underlying mechanisms of stroke, however, gender differences in aphasia type and severity remain unclear. AIMS: To examine gender differences in aphasia impairment based on data from AphasiaBank, a research repository of data obtained from studies of aphasia. METHODS & PROCEDURES: The data were collected from AphasiaBank for 294 persons with aphasia (PWA) (172 men, 122 women). Baseline comparisons by gender groups were completed using independent samples t-tests and Pearson Chi square statistics. Univariate comparisons of the total Western Aphasia Battery-Revised (WAB-R) -AQ and -R subtests' scores were compared between the two groups using independent samples t-tests. Multivariate comparisons were completed by using multivariate analysis of variance (MANOVA). OUTCOMES & RESULTS: Gender differences were observed in the severity of aphasia with men exhibiting more severe aphasia than women. Analyses of WAB-R indicated greater impairment among men based on AQ and greater impairment was observed in individual subtest performance. Men exhibited statistically significantly lower WAB-R AQs than women (67.4 versus 75.6). Lower WAB-R AQs were derived from lower scores among men on individual subtests; information content, fluency, repetition, sentence completion, responsive speech and tests of comprehension (yes/no, auditory word recognition and sequential commands). CONCLUSIONS & IMPLICATIONS: This study offers evidence of gender differences in aphasia severity, global communication impairment and lower scores on individual subtests used to derive the WAB-R AQ. The limitations of the study with suggestions for future directions are presented.

Barriers and Facilitators of Stroke Recovery: Perspectives From African Americans With Stroke, Caregivers and Healthcare Professionals.

INTRODUCTION AND GOAL: Stroke is a serious health condition that disproportionally affects African-Americans relative to non-Hispanic whites. In the absence of clearly defined reasons for racial disparities in stroke recovery and subsequent stroke outcomes, a critical first step in mitigating poor stroke outcomes is to explore potential barriers and facilitators of poststroke recovery in African-American adults with stroke. The purpose of this study was to qualitatively explore poststroke recovery across the care continuum from the perspective of African-American adults with stroke, caregivers of African-American adults with stroke, and health care professionals with expertise in stroke care. MATERIALS AND METHODS: This qualitative descriptive study included in-depth key informant interviews with health care providers (n = 10) and focus groups with persons with stroke (n = 20 persons) and their family members or caregivers (n = 19 persons). Data were analyzed using thematic analysis according to the Social Ecological Model, using both inductive and deductive approaches. FINDINGS: Persons with stroke and their caregivers identified social support, resources, and knowledge as the most salient factors associated with stroke recovery. Perceived barriers to recovery included: (1) physical and cognitive deficits, mood; (2) medication issues; (3) lack of support and resources; (4) stigma, culture, and faith. Health care providers identified knowledge/information, care coordination, and resources in the community as key to facilitating stroke recovery outcomes. CONCLUSIONS: Key findings from this study can be incorporated into interventions designed to improve poststroke recovery outcomes and potentially reduce the current racial-ethnic disparity gap.

Social Network Structure in Young Stroke Survivors with Aphasia: A Case Series Report.

The aim of this study was to profile the social networks of young adult stroke survivors with aphasia. A case series approach using four persons with aphasia (PWA) younger than 50 years was utilized. Semistructured interviews were completed with the PWA and their primary caregiver/family to explore the most salient relationships in the PWA's social network. PWAs in this study exhibited very small social networks with the most salient relationships consisting of immediate family members. Mothers were the primary caregiver for the two most impaired PWA. Prestroke friendships were dissolved or reduced at the onset of aphasia. The most impaired PWAs spent most of their days in isolation without a consistent communication partner. This study suggests young adult stroke survivors with aphasia have significant changes in their social network structure after stroke, but it is unclear if the observed change in social network structure is more related to age or level of communication impairment.

Insulin resistance is a significant determinant of sarcopenia in advanced kidney disease.

Maintenance hemodialysis (MHD) patients display significant nutritional abnormalities. Insulin is an anabolic hormone with direct effects on skeletal muscle (SM). We examined the anabolic actions of insulin, whole-body (WB), and SM protein turnover in 33 MHD patients and 17 participants without kidney disease using hyperinsulinemic-euglycemic-euaminoacidemic (dual) clamp. Gluteal muscle biopsies were obtained before and after the dual clamp. At baseline, WB protein synthesis and breakdown rates were similar in MHD patients. During dual clamp, controls had a higher increase in WB protein synthesis and a higher suppression of WB protein breakdown compared with MHD patients, resulting in statistically significantly more positive WB protein net balance [2.02 (interquartile range [IQR]: 1.79 and 2.36) vs. 1.68 (IQR: 1.46 and 1.91) mg·kg fat-free mass-1·min-1 for controls vs. for MHD patients, respectively, P < 0.001]. At baseline, SM protein synthesis and breakdown rates were higher in MHD patients versus controls, but SM net protein balance was similar between groups. During dual clamp, SM protein synthesis increased statistically significantly more in controls compared with MHD patients ( P = 0.03), whereas SM protein breakdown decreased comparably between groups. SM net protein balance was statistically significantly more positive in controls compared with MHD patients [67.3 (IQR: 46.4 and 97.1) vs. 15.4 (IQR: -83.7 and 64.7) µg·100 ml-1·min-1 for controls and MHD patients, respectively, P = 0.03]. Human SM biopsy showed a positive correlation between glucose and leucine disposal rates, phosphorylated AKT to AKT ratio, and muscle mitochondrial markers in controls but not in MHD patients. Diminished response to anabolic actions of insulin in the stimulated setting could lead to muscle wasting in MHD patients.

Commentary: Addressing Racial Disparities in Stroke: The Wide Spectrum Investigation of Stroke Outcome Disparities on Multiple Levels (WISSDOM).

Racial-ethnic disparities in stroke recovery are well-established in the United States but the underlying causes are not well-understood. The typical assumption that racial-ethnic disparities in stroke recovery are explained by health care access inequities may be simplistic as access to stroke-related rehabilitation, for example, does not adequately explain the observed disparities. To approach the problem in a more comprehensive fashion, the Wide Spectrum Investigation of Stroke Outcome Disparities on Multiple Levels (WISSDOM) was developed to bring together scientists from Regenerative Medicine, Neurology, Rehabilitation, and Nursing to examine disparities in stroke "recovery." As a result, three related projects (basic science, clinical science and population science) were designed utilizing animal modeling, mapping of brain connections, and community-based interventions. In this article we describe: 1) the goals and objectives of the individual projects; and 2) how these projects could provide critical evidence to explain why racial-ethnic minorities traditionally experience recovery trajectories that are worse than Whites.

Dietary Practices Among Stroke-survivors-Racial/Ethnic Differences.

BACKGROUND: Healthy lifestyle choices, particularly optimal nutrition, are crucial to stroke prevention and reducing risk of recurrent stroke. Racial differences exist in poststroke outcomes; however, few studies have examined the influence of race on poststroke diet or nutrition practices, despite nutrition being critical to stroke recovery. The objective of this analyzes was therefore to examine racial/ ethnic differences in nutrition activities among stroke survivors using data from the National Health and Nutrition Examination Surveys. METHODS: Cross-sectional data from National Health and Nutrition Examination Surveys (2011-2014) were analyzed for adults (n = 431) who responded "yes" that they had been told by a health professional that they had a stroke. The main outcome measure was food consumption/nutrition behavior. Descriptive statistics were conducted for demographic characteristics. Pearson Chi square statistics were performed for baseline demographic and clinical comparisons. A negative binomial regression analysis was utilized for racial/ethnic comparisons of dietary/nutrition behaviors. RESULTS: The mean age of the sample was 66.6 years (Standard Deviation, 12.7) but the mean age of stroke onset was 57.9 years (Standard Deviation, 15.8), with Mexican American/Hispanics experiencing their strokes at a younger age than other racial groups (P < .007). After controlling for baseline differences in key demographic and clinical covariates variables, Blacks consumed a higher number of ready-to-eat foods (P = .000) in the past 30 days while Mexican American/Hispanics consumed a higher number of frozen meals/pizza in the past 30 days (P = .004). CONCLUSIONS: Racial/ethnic differences in poststroke nutrition practices, highlight a potential need for focused nutrition counseling for minority population at higher risk of poor poststroke outcomes.
