Exploring Barriers to Effective COVID-19 Risk Mitigation, Recovery, and Chronic Disease Self-Management: A Qualitative Multilevel Perspective.

Introduction: Many research activities have focused on SARS-CoV-2 infection and subsequent COVID-19 respiratory illness during the pandemic. However, significant racial inequities emerged months after the COVID-19 pandemic began. The similarity between racial/ ethnic disparities in COVID-19 and those for other diseases raised awareness about the context for risk exposure and healthcare access. The purpose of this study is to examine social and structural determinants of health among COVID-19 survivors, carepartners, and the perspectives of healthcare stakeholders who experienced disruption during the early pandemic. Material and methods: A purposive sample of interviews (n=9) and focus groups (n=10) were used to collect data regarding knowledge of barriers to effective COVID-19 risk mitigation, recovery, and chronic disease self-management. This included nurses, physicians, COVID-19 survivors and their carepartners, public health, and community leaders connected with the healthcare systems in rural counties of South Carolina. Results: Five major themes were identified across the subgroups. The themes: The COVID-19 Illness Trajectory Added Major Health Challenges and Stressors, Access to Care Is Lacking, Support is Needed for COVID-19 Survivors and Care Partners, Support Must be Distributed Equitably, and Racism and Structural Issues Affect Stress reflect the strengths, opportunities, and inequities perceived within these groups. Conclusion: This research is the first qualitative study focused on COVID-19 survivor-carepartner dyads that consider the intersectionality of race/ ethnicity, geography, and health that is known to occur when engaging healthcare systems. The themes illustrate the need for infectious disease prevention at all socioecological levels: structural/ systemic, community, organizational/ institutional, interpersonal, and individual.

Working-Age Caregivers of Stroke Survivors: Needs, Concerns, and Quality of Life.

PURPOSE: The purpose of this study was to characterize the unmet needs and concerns of working-age caregivers of stroke survivors and to explore the relationships between these unmet needs and concerns and factors such as stroke survivor functional independence, caregiver strain, caregiver self-efficacy, caregiver perceived social support, and caregiver quality of life (QoL). DESIGN: Cross-sectional descriptive design was used in this study. METHODS: Participants ( N = 103) completed an online survey. Descriptive statistics, bivariate Pearson correlation, and linear regression analysis was performed. RESULTS: Negative correlations were found between caregiver needs and concerns and both stroke survivor functional independence and caregiver self-efficacy. Positive correlations were identified between caregiver needs and concerns and caregiver strain. In multiple regression models, stroke survivor functional independence, caregiver self-efficacy, race, and gender were statistically significantly associated with caregiver QoL. CLINICAL RELEVANCE TO THE PRACTICE OF REHABILITATION NURSING: Results of this study can inform nurses as they collaborate with informal caregivers and researchers in optimizing the rehabilitation and discharge process and aiding in the support of caregiver QoL. CONCLUSION: Working-age caregivers of stroke survivors expressed many needs and concerns. These needs, along with other factors, can affect outcomes including QoL in caregivers and stroke survivors.

Neighborhoods and Cardiovascular Health: A Scientific Statement From the American Heart Association.

The neighborhoods where individuals reside shape environmental exposures, access to resources, and opportunities. The inequitable distribution of resources and opportunities across neighborhoods perpetuates and exacerbates cardiovascular health inequities. Thus, interventions that address the neighborhood environment could reduce the inequitable burden of cardiovascular disease in disenfranchised populations. The objective of this scientific statement is to provide a roadmap illustrating how current knowledge regarding the effects of neighborhoods on cardiovascular disease can be used to develop and implement effective interventions to improve cardiovascular health at the population, health system, community, and individual levels. PubMed/Medline, CINAHL, Cochrane Library reviews, and ClinicalTrials.gov were used to identify observational studies and interventions examining or targeting neighborhood conditions in relation to cardiovascular health. The scientific statement summarizes how neighborhoods have been incorporated into the actions of health care systems, interventions in community settings, and policies and interventions that involve modifying the neighborhood environment. This scientific statement presents promising findings that can be expanded and implemented more broadly and identifies methodological challenges in designing studies to evaluate important neighborhood-related policies and interventions. Last, this scientific statement offers recommendations for areas that merit further research to promote a deeper understanding of the contributions of neighborhoods to cardiovascular health and health inequities and to stimulate the development of more effective interventions.

Community Trust, Attitudes and Preferences Related to Participation in Cancer Research in South Carolina.

African American adults have the highest mortality rate for most cancers in the United States, and meaningful, community-driven research is needed to inform optimal strategies for addressing these disparities. Unfortunately, research mistrust, often driven by historical inequities, is well-documented among African Americans.This study explored trust, attitudes, and preferences regarding participation in cancer research activities among primarily African American and other medically underserved communities in South Carolina from August 2020 to December 2021. Trust was measured using the Trust in Medical Researchers Scale (TMRS).The mean TMRS score for all study participants (N = 179) was 26.54 (SD 7.57) out of 48 (maximum possible score). Significant differences in mean values of the TMRS scores were only observed for gender (p = 0.0056) and race (p < 0.0001), with White participants and males reporting higher levels of trust in medical researchers. Overall, 52.5% of participants were somewhat likely or likely to volunteer to participate in a cancer research opportunity, with White participants (73.81%) being more likely to participate in cancer research compared to African American participants (45.74%) (p = 0.0054). Furthermore, participants were most willing to provide saliva (80.85%) and urine samples (80.85%), new blood samples (60.64%), stool samples (54.26%), medical records or laboratory results (52.13%) and least willing to allow left-over blood, tissue, or other fluids from medical procedures to be used for research (50%).These results provide evidence of the need for concerted programmatic efforts to build trust in cancer researchers, particularly among females and African American adults.

Exploring Nursing Strategies to Engage Community in Cardiovascular Care.

PURPOSE OF REVIEW: This review aims to highlight some of the strategies nurses use to engage community members in cardiovascular care. We also elaborate on opportunities for improving community engagement. RECENT FINDINGS: Community engagement occurs across a continuum of progressive levels of community involvement, impact, trust, and flow of communication. Successful community engagement has been shown to improve both patient-centered care and intervention design, implementation, and dissemination. Nurse strategies used for engaging community in cardiovascular care included more examples of outreach, consult, and involvement than collaboration and shared leadership. More attention is needed toward strategies that embrace collaboration and enhance trusting relationships to advance to shared leadership. Nurses must intentionally work in partnership with communities to improve cardiovascular health for all. Furthermore, assessing meaningful community engagement is necessary to achieve the desired outcomes, including optimal cardiovascular health and thriving communities.

Unlocking Population-Specific Treatments to Render Equitable Approaches and Management in Cardiovascular Disease: Development of a Situation-Specific Theory for African American Emerging Adults.

BACKGROUND: Emerging adulthood (18-25 years old) is a distinct developmental period in which multiple life transitions pose barriers to engaging in healthy lifestyle behaviors that reduce cardiovascular disease risk. There is limited theory-based research on African American emerging adults. OBJECTIVE: This article introduces a synthesized empirically testable situation-specific theory for cardiovascular disease prevention in African American emerging adults. METHODOLOGY: Im and Meleis' integrative approach was used to develop the situation-specific theory. RESULTS: Unlocking Population-Specific Treatments to Render Equitable Approach and Management in Cardiovascular Disease is a situation-specific theory developed based on theoretical and empirical evidence and theorists' research and clinical practice experiences. DISCUSSION: African American emerging adults have multifaceted factors that influence health behaviors and healthcare needs. Unlocking Population-Specific Treatments to Render Equitable Approaches and Management in Cardiovascular Disease has the potential to inform theory-guided clinical practice and nursing research. Recommendations for integration in nursing practice, research, and policy advocacy are presented. Further critique and testing of the theory are required.

Cardiovascular Disease Risk Factors in Women: The Impact of Race and Ethnicity: A Scientific Statement From the American Heart Association.

Cardiovascular disease is the leading cause of death in women, yet differences exist among certain racial and ethnic groups. Aside from traditional risk factors, behavioral and environmental factors and social determinants of health affect cardiovascular health and risk in women. Language barriers, discrimination, acculturation, and health care access disproportionately affect women of underrepresented races and ethnicities. These factors result in a higher prevalence of cardiovascular disease and significant challenges in the diagnosis and treatment of cardiovascular conditions. Culturally sensitive, peer-led community and health care professional education is a necessary step in the prevention of cardiovascular disease. Equitable access to evidence-based cardiovascular preventive health care should be available for all women regardless of race and ethnicity; however, these guidelines are not equally incorporated into clinical practice. This scientific statement reviews the current evidence on racial and ethnic differences in cardiovascular risk factors and current cardiovascular preventive therapies for women in the United States.

Multilevel Intervention to Improve Racial Equity in Access to Kidney Transplant.

BACKGROUND: African Americans (AAs) have reduced access to kidney transplant (KTX). Our center undertook a multilevel quality improvement endeavor to address KTX access barriers, focused on vulnerable populations. This program included dialysis center patient/staff education, embedding telehealth services across South Carolina, partnering with community providers to facilitate testing/procedures, and increased use of high-risk donors. STUDY DESIGN: This was a time series analysis from 2017 to 2021 using autoregression to assess trends in equitable access to KTX for AAs. Equity was measured using a modified version of the Kidney Transplant Equity Index (KTEI), defined as the proportion of AAs in South Carolina with end-stage kidney disease (ESKD) vs the proportion of AAs initiating evaluation, completing evaluation, waitlisting, and undergoing KTX. A KTEI of 1.00 is considered complete equity; a KTEI of <1.00 is indicative of disparity. RESULTS: From January 2017 to September 2021, 11,487 ESKD patients (64.7% AA) were referred, 6,748 initiated an evaluation (62.8% AA), 4,109 completed evaluation (59.7% AA), 2,762 were waitlisted (60.0% AA), and 1,229 underwent KTX (55.3% AA). The KTEI for KTX demonstrated significant improvements in equity. The KTEI for initiated evaluations was 0.89 in 2017, improving to 1.00 in 2021 (p = 0.0045). Completed evaluation KTEI improved from 0.85 to 0.95 (p = 0.0230), while waitlist addition KTEI improved from 0.83 to 0.96 (p = 0.0072). The KTEI for KTX also improved from 0.76 to 0.91, which did not reach statistical significance (p = 0.0657). CONCLUSIONS: A multilevel intervention focused on improving access to vulnerable populations was significantly associated with reduced disparities for AAs.

Use and efficacy of virtual, augmented, or mixed reality technology for chronic pain: a systematic review.

Aim: Characterize use and efficacy/effectiveness of virtual, augmented, or mixed reality (VR/AR/MR) technology as non-pharmacological therapy for chronic pain. Methods: Systematic search of 12 databases to identify empirical studies, of individuals who experience chronic pain or illness involving chronic pain, published between 1990 and 2021. JBI Critical Appraisal Checklists assessed study bias and a narrative synthesis was provided. Results: 46 studies, investigating a total of 1456 participants and including 19 randomized controlled trials (RCT), were reviewed. VR/AR/MR was associated with improved pain-related outcomes in 78% of the RCTs. Conclusion: While most studies showed effects immediately or up to one month post treatment, RCTs are needed to further evaluate VR/AR/MR, establish long-term benefits, and assess accessibility, especially among individuals who experience pain management disparities.

Virtual, augmented and mixed reality (VR/AR/MR) are technologies that can be used to manage chronic pain. The use and effectiveness of VR/AR/MR were examined during a review of 46 research studies, which included 1456 participants and 19 randomized controlled trials (RCTs). In 78% of the RCTs, VR/AR/MR improved pain or pain-related outcomes. While most studies showed a benefit on pain immediately or up to 1 month after treatment, more research is needed to assess the long-term benefits of VR/AR/MR on pain and understand how these technologies provide pain relief in the body. Additionally, the accessibility and cost­effectiveness of VR/AR/MR must be evaluated. These areas for future research must consider individuals who experience disparities in the treatment of chronic pain.

Surgical Outcomes Improvement and Health Inequity in a Regional Quality Collaborative.

BACKGROUND: Surgical quality improvement initiatives may impact sociodemographic groups differentially. The objective of this analysis was to assess the trajectory of surgical morbidity by race and age over time within a Regional Collaborative Quality Initiative. STUDY DESIGN: Adults undergoing eligible general surgery procedures in South Carolina Surgical Quality Collaborative hospitals were analyzed for the presence of at least 1 of 22 morbidities between August 2015 and February 2020. Surgery-level multivariable logistic regression assessed the racial differences in morbidity over time, stratified by age group (18 to 64 years, 65 years and older), and adjusting for potential patient- and surgical-level confounders. RESULTS: A total of 30,761 general surgery cases were analyzed, of which 28.4% were performed in Black patients. Mean morbidity rates were higher for Black patients than non-Black patients (8.5% vs 6.0%, p < 0.0001). After controlling for race and other confounders, a significant decrease in monthly mean morbidity through time was observed in each age group (odds ratio [95% CI]: age 18 to 64 years, 0.986 [0.981 to 0.990]; age 65 years and older, 0.991 [0.986 to 0.995]). Comparing morbidity rates from the first 4 months of the collaborative to the last 4 months reveals older Black patients had an absolute decrease in morbidity of 6.2% compared with 3.6% for older non-Black patients. Younger Black patients had an absolute decrease in morbidity of 4.7% compared with a 3.0% decrease for younger non-Black patients. CONCLUSIONS: Black patients had higher morbidity rates than non-Black patients even when controlling for confounders. The reasons for these disparities are not apparent. Morbidity improved over time in all patients with older Black patients seeing a larger absolute decrease in morbidity.

'Timing it Right': needs of African American adults with stroke and their caregivers across the care continuum.

Objective: African Americans are disproportionately affected by stroke in the United States (US). The purpose of this study is to explore experiences, wants, and needs of African Americans with stroke and their family caregivers residing in the stroke belt across the care continuum using the 'Timing It Right' (TIR) framework as a conceptual guide.Design: We conducted a series of focus groups among 20 African Americans living with stroke and 19 family caregivers. Focus groups were audio-recorded and transcribed verbatim. For this secondary analysis, we coded qualitative data using the TIR framework.Results: Participants in this sample identified pre-stroke needs in addition to the TIR phases that span across the care continuum and into community living. We identified four important contextual factors and real-world conditions that operate in the background and influence the post-stroke needs of this specific population across the TIR framework: (1) religion, faith, and church, (2) healthcare delivery, (3) community, and (4) sentinel events.Conclusions: We propose a TIR model that expands upon the original TIR framework which includes factors important for consideration when developing and delivering community-based interventions among African Americans with stroke and family caregivers in the southeastern US.

High tech and high touch: Recruitment strategies for enrolling African American stroke survivors in Community Based Intervention under Nurse Guidance after stroke (CINGS) trial.

BACKGROUND: Substantial effort has been undertaken to improve the recruitment and retention of participants in stroke trials. African Americans are disproportionately under-represented in stroke clinical trials as well as clinical trials for other chronic disease conditions. To circumvent barriers to recruitment, clinical trial recruitment strategies used to recruit African Americans have focused on different aspects of community engagement. PURPOSE: This study examined a community-engaged, multi-phased tailored approach to recruiting African Americans with stroke. The recruitment approach described was designed to support the Community Based Intervention under Nurse Guidance after Stroke (CINGS) trial, part of the Wide Spectrum Investigation of Stroke Outcome Disparities on Multiple Levels (WISSDOM) Center established to explore stroke disparities. METHODS: A multiple-phased recruitment approach was undertaken and involved a recruitment planning phase and a recruitment phase. The recruitment planning phase involved the use of focus groups designed to explore barriers and facilitators of stroke recovery. The active recruitment phase included multiple strategies with ongoing evaluation. RESULTS: Information gained from focus groups offered insights into strategies critical to recruiting African Americans with stroke for behavioral research during the early recovery period. Strategies to enhance the identification of and recruitment of potential participants included use of: a) a hospital system stroke database, b) system-wide friendly visits/warm handoff approaches, c) electronic health record, d) associated external sites and e) protocol adjustments. CONCLUSIONS: Developing tailored approaches to curtail barriers to research participation is critical for increasing the probability of reaching African American study participant recruitment and retention goals. Research teams may require training in community-engagement research strategies essential for obtaining achieving target recruitment goals.

Racial Differences in Blood Pressure Control Following Stroke: The REGARDS Study.

BACKGROUND AND PURPOSE: In the general population, Black adults are less likely than White adults to have controlled blood pressure (BP), and when not controlled, they are at greater risk for stroke compared with White adults. High BP is a major modifiable risk factor for recurrent stroke, but few studies have examined racial differences in BP control among stroke survivors. METHODS: We used data from the REGARDS study (Reasons for Geographic and Racial Differences in Stroke) to examine disparities in BP control between Black and White adults, with and without a history of stroke. We studied participants taking antihypertensive medication who did and did not experience an adjudicated stroke (n=306 and 7693 participants, respectively) between baseline (2003-2007) and a second study visit (2013-2016). BP control at the second study visit was defined as systolic BP <130 mm Hg and diastolic BP <80 mm Hg except for low-risk adults ≥65 years of age (ie, those without diabetes, chronic kidney disease, history of cardiovascular disease, and with a 10-year predicted atherosclerotic cardiovascular disease risk <10%) for whom BP control was defined as systolic BP <130 mm Hg. RESULTS: Among participants with a history of stroke, 50.3% of White compared with 39.3% of Black participants had controlled BP. Among participants without a history of stroke, 56.0% of White compared with 50.2% of Black participants had controlled BP. After multivariable adjustment, there was a tendency for Black participants to be less likely than White participants to have controlled BP (prevalence ratio, 0.77 [95% CI, 0.59-1.02] for those with a history of stroke and 0.92 [95% CI, 0.88-0.97] for those without a history of stroke). CONCLUSIONS: There was a lower proportion of controlled BP among Black compared with White adults with or without stroke, with no statistically significant differences after multivariable adjustment.

Effectiveness of dyadic interventions to improve stroke patient-caregiver dyads' outcomes after discharge: A systematic review and meta-analysis study.

BACKGROUND: Because of the importance of a dyadic approach, it is necessary to conduct a systematic review to identify which dyadic intervention could be implemented for stroke survivor-caregiver dyads after discharge from the rehabilitation hospital to improve outcomes. AIMS: The aims were to systematically review the evidence to identify which dyadic interventions have been implemented in stroke survivor-caregiver dyads to improve stroke survivor-caregiver dyads' outcomes and to analyse, through a meta-analysis, which intervention was found to be the most effective. METHODS: A systematic review and meta-analysis were conducted using the following electronic databases: PubMed, CINAHL and PsycInfo. Randomized controlled trials (RCTs) and quasi-RCT studies published within the last 10 years were included. Quantitative data were extracted from papers included in the review using the standardized data extraction tool from JBI-MAStARI. Pooled effects were analysed between the experimental and control groups for each outcome. RESULTS: Sixteen studies involving 2997 stroke survivors (male gender=58%) and 2187 caregivers (male gender=25%) were included in this review. In 16 studies, which were subdivided into three quasi-RCTs and 13 RCTs, the application of dyadic interventions for stroke survivors and caregivers was systematically reviewed, but only a few of these identified a significant improvement in the stroke survivors' and caregivers' outcomes of its intervention group. Dyadic interventions showed a significant effect on stroke survivors' physical functioning (p=0.05), memory (p<0.01) and quality of life (p=0.01) and on caregivers' depression (p=0.05). CONCLUSIONS: This study provides moderate support for the use of a dyadic intervention to improve stroke survivors' physical functioning, memory and quality of life and caregiver depression.

Lessons Learned from the Medical University of South Carolina Transdisciplinary Collaborative Center (TCC) in Precision Medicine and Minority Men's Health.

The Transdisciplinary Collaborative Center (TCC) in Precision Medicine for Minority Men's Health was established at the Medical University of South Carolina (MUSC) in 2015 to address disparities in the translation of precision medicine approaches among racial minority groups. This regional consortium focuses on three primary areas: (1) the development of a consortium of regional and national partners, (2) conducting transdisciplinary research examining synergistic effects of biological, social, physiological, and clinical determinants of chronic disease risks and outcomes, and (3) dissemination and implementation of precision medicine approaches, with an emphasis on reducing disparities in health care and outcomes among minority men. Given consistent calls to better translate precision medicine approaches and the focus of this consortium on addressing disparities among minority men, we provide an overview of our experience in developing the MUSC TCC, including barriers and facilitators to conducting translational research on minority men's health issues in the context of precision medicine. Lessons learned and areas for improvement include providing enough time to create consistent partnerships and community engagement to improve recruitment and retention, identifying unique ways to engage diverse partners from across the region and nation, and better approaches to dissemination and communication for large partnerships focusing on precision medicine.

Development and Validation of a Multidimensional Instrument: Assessing Barriers to Dietary Practices.

BACKGROUND AND PURPOSE: Poor dietary practices are linked to many chronic diseases. The purpose of this validation study was to develop a psychometrically sound instrument that can be administered by health practitioners to measure dietary barriers. METHODS: The Dietary Health Status (DHS) instrument, designed to measure dietary barriers is comprised of items in the National Health and Nutrition Examination Survey-What We Eat in America datasets. Content validity was established for DHS using an expert review process. Principal component analysis (PCA) was then used to assess validity and reliability as determined by Cronbach's alpha values. RESULTS: The PCA supported a 10-component solution, explaining 61% of the total variance. Cronbach's alpha was .67 for the entire instrument, ranging from .55 to .87 for the 10 subscales. CONCLUSION: Results suggest the instrument had sufficient construct and internal validity. This exploratory study is an important first step in validating the DHS instrument.

Community-Based Interventions for Stroke Provided by Nurses and Community Health Workers: A Review of the Literature.

BACKGROUND: Community-based interventions are vital for facilitating poststroke recovery, increasing community participation, and raising awareness about stroke survivors. To optimize recovery and community reintegration, there is a need to understand research findings on community-based interventions that focus on stroke survivors and their caregivers. Although nurses and community health workers (CHWs) are commonly involved in community-based interventions, less is known about their roles relative to other poststroke rehabilitation professionals (physical therapists, occupational therapists, and speech-language pathologists). Thus, the purpose of this review is to explore research focused on improving community-based stroke recovery for adult stroke survivors, caregivers, or both when delivered by nurses or CHWs. METHODS: A systematic review using Scopus, PubMed, EBSCOhost, MEDLINE, CINAHL Complete, and PsycInfo was completed to identify community-based poststroke intervention studies using nurses or CHWs through August 2018. RESULTS: Eighteen studies meeting inclusion criteria from 9 countries were identified. Details regarding nurses' and CHWs' roles were limited or not discussed. Interventions emphasized stroke survivor self-care and caregiver support and were offered face-to-face and in group sessions in the community and home. A wide range of instruments were used to measure outcomes. The results of the interventions provided were mixed. Improvements were observed in perceptions of health, quality of life, knowledge, self-efficacy, self-management, and caregiver support. CONCLUSION: Nurses and CHWs play a pivotal role in community-based care. Evidence suggests community-based interventions facilitate the necessary support for stroke survivors, caregivers, families, and communities to optimize stroke recovery. Data from this review illustrate a continued need for comprehensive programs designed to address the complex needs of stroke survivors and families when they return to their homes and communities.

Establishing content validity for a conceptualized instrument to measure barriers to eating a healthful diet in adults: a consensus approach.

BACKGROUND: A poor quality diet is a well-known risk factor for many chronic diseases. However, eating a healthful diet is not always simple as many underlying factors can impede adherence. Individuals with fewer barriers are more likely to eat a healthful diet than those who have more barriers. Accurately measuring barriers to eating a healthful diet could inform personalized interventions, particularly those aiming to prevent chronic diseases. The aim of this study was to establish content validity for selected items obtained from the National Health and Nutrition Examination Survey (NHANES) database to be considered for inclusion as items on the conceptualized Dietary Health Status (DHS) instrument, which is designed to measure barriers to eating a healthful diet in adults. METHODS: The Behavioral Change Wheel hub COM-B and the Theoretical Domains Framework (TDF) were the two theoretical frameworks underpinning the development of the DHS instrument. Seven steps were conducted to create the instrument: 1) development of operational definitions for each TDF domain; 2) identification of items from the NHANES database 2011-2012; 3) screening of items to ensure inclusion of all relevant items; 4) assigning items to a theory-based domain; 5) evaluation of the items against inclusion/exclusion criteria; 6) solicitation of feedback from expert reviewers to reach consensus on inclusion into a domain; and 7) validation of items. RESULTS: A total of 170 items representing twelve domains were identified as potential barriers to eating a healthful diet-- knowledge, optimism, beliefs about consequences, beliefs about capabilities, reinforcement, memory, attention and decision processes, environmental context and resources, social influences, emotion, behavioral regulation, health identity, and functional status. CONCLUSION: Expert review consultation and a consensus approach established content validity for 12 theory-based domains comprised of 170 items identified as potential barriers to eating a healthful diet. The use of these explanatory domains may: assist researchers to better understand barriers to adult dietary practices; inform the development of a screening tool that could be used in a community setting to measure barriers to eating a healthful diet; and inform individualized interventions.

Serum Amyloid A-Mediated Inflammasome Activation of Microglial Cells in Cerebral Ischemia.

Serum amyloid A (SAA) proteins are acute-phase reactant associated with high-density lipoprotein (HDL) particles and increase in the plasma 1000-fold during inflammation. Recent studies have implicated SAAs in innate immunity and various disorders; however, the precise mechanism eludes us. Previous studies have shown SAAs are elevated following stroke and cerebral ischemia, and our studies demonstrated that SAA-deficient mice reduce inflammation and infarct volumes in a mouse stroke model. Our studies demonstrate that SAA increases the cytokine interleukin-1ß (IL-1ß), which is mediated by Nod-like receptor protein 3 (NLRP3) inflammasome, cathepsin B, and caspase-1 and may play a role in the pathogenesis of neurological disorders. SAA induced the expression of NLRP3, which mediated IL-1ß induction in murine BV-2 cells and both sex primary mouse microglial cells, in a dose- and time-dependent fashion. Inhibition or KO of the NLRP3 in microglia prevented the increase in IL-1ß. N-acetyl-l-cysteine and mito-TEMPO blocked the induction of IL-1ß by inhibiting ROS with SAA treatment. In addition, inhibition of cathepsin B with different drugs or microglia from CatB-deficient mice attenuated inflammasome activation. Our studies suggest that the impact of SAA on inflammasome stimulation is mediated in part by the receptor for advanced glycation endproducts and Toll-like receptor proteins 2 and 4. SAA induced inflammatory cytokines and an M1 phenotype in the microglial cells while downregulating anti-inflammation M2 phenotype. These studies suggest that brain injury to can elicit a systemic inflammatory response mediated through SAA that contributes to the pathological outcomes.SIGNIFICANCE STATEMENT In the present study, serum amyloid A can induce that activation of the inflammasome in microglial cells and give rise to IL-1ß release, which can further inflammation in the brain following neurological diseases. The also presents a novel target for therapeutic approaches in stroke.

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.
