BACKGROUND:Black men are underrepresented in hypertension trials, even though this population has higher prevalence and more adverse sequelae from hypertension, compared to other groups. In this article we present recruitment and community engagement strategies for the Community-to-Clinic Linkage Implementation Program (CLIP), a cluster-randomized trial on hypertension prevention among Black men. METHODS:Using a 2-stage recruitment process: 1) we enrolled Black-owned barbershops from zip-codes with high hypertension prevalence; and 2) recruited Black male participants who fulfilled the eligibility criteria and were customers of the barbershops. Barbershop and participant recruitment was conducted by a partner community-based organization. RESULTS:The study met the recruitment goals for barbershop enrollment (N=22) and individual participants. Of eligible individuals (N=461), 430 enrolled in the study (93% consent rate, exceeding the original enrollment goal of N=420 participants). Throughout recruitment, the study team conducted 101 unique engagements (41 prior to recruitment, 60 during recruitment), totaling engagement with180 partners across all events, including individual and group meetings, attendance at community events, and educational presentations. In addition to a primary partner community organization, the study team collaborated with a Community Advisory Council, comprised of residents, and civic and community leaders, and with the local health department and varied other organizations. CONCLUSIONS:In CLIP, a high number of academic-community engagement encounters and close collaboration with community partners contributed to successful recruitment of Black men at risk for hypertension and with adverse social determinants. Our experience may serve as to inform investigators focused on recruiting underserved populations in hypertension research trials.

BACKGROUND:Epilepsy self-management (ESM) by people living with epilepsy (PWE) can reduce seizure frequency and increase quality of life (QOL). ESM among Hispanic PWE is under-investigated and lacks adequate sampling and ESM assessment. The purpose of this study was to assess ESM and associated variables among Hispanic PWE using aggregate data from the Managing Epilepsy Well Network Integrated Database. METHODS:The sample comprised Hispanic PWE (n = 211) from nine ESM intervention studies that used common measures for socio-demographics, health status, prior 30- day seizures, depression (PHQ-9, NDDI-E), QOL (QOLIE-10), and ESM. RESULTS:The sample was 39.3 (±12.8) years, mostly female (56.1 %), preferring Spanish language (59 %), U.S. born (62.2 %), high school or college educated (35.7 %), single/partnered (43.9 %/41.0 %), employed/unemployed (33.0 %/32.1 %), with income <$25,000 (59.0 %), with depressive symptoms (35.1 %), and a seizure in the past month (52.5 %). Total ESM item mean scores were positively skewed (3.6 ± 0.4 on a 5-point scale). Medication, seizure, and safety management exceeded that for information and lifestyle management. In adjusted multivariable models, medication management was associated with age and employment (homemaker) and inversely associated with marital status (never married) and depression. Lifestyle management was associated with employment (unable to work) and inversely associated with sex (female), depression, and QOL. CONCLUSION/CONCLUSIONS:Hispanic PWE were more competent in managing the medical aspects of their condition than lifestyle and informational issues. This study is significant because it leverages the analytic power of a large aggregate Hispanic PWE sample to describe ESM and can inform future study design, data collection, and tailoring of ESM interventions.

Social determinants of health (SDoH), health care use, and cardiovascular disease (CVD) risk perception are understudied among men who identify as Black and Hispanic. In this study we sought to describe these factors among a cohort of urban-residing Black men, participants in a community-engaged trial on hypertension prevention. We focused on presenting intermediary SDoH, including material circumstances, health behaviors, and psychosocial factors, which allow for a more robust understanding of health inequities but are underexplored. We analyzed baseline trial data (N=430) and compared subgroups (44% of participants self-identified as having Hispanic ethnicity and a Black racial identity). Average age was 38 years, with mean blood pressure of 129/83 mmHg. Hispanic Black (HB) men reported higher unemployment (21.4% versus 11.1%, P=.02) and more housing instability (28.7% versus 18.6%, P=.01) than did non-Hispanic Black (NHB) men. Overall, HB men reported worse household conditions compared with NHB men. Approximately half of both groups reported high stress, 45% (HB) and 51% (NHB), respectively. Both groups had low perception of personal CVD risk and underutilized health care. Hispanic Black men were less likely to have a primary care provider than were NHB men (17.6% versus 29.3%, P<.001). Non-Hispanic Black men reported lower physical activity than did HB men (median, 2655 vs 2547 metabolic equivalent minutes/week, P=.03). Recognizing heterogeneity among Black populations, including in social drivers of CVD disparities, will allow for more precision in designing CVD health promotion interventions. Findings also suggest that perception of personal CVD risk and health care utilization may be important targets for CVD prevention in Black men.

UNLABELLED:There are limited data on psychosocial functioning in young adults with epilepsy (YAWE) despite myriad milestones during this life stage. OBJECTIVE:The purpose of this study was to analyze aggregate data from the Managing Epilepsy Well Network Integrated Database (MEW-DB) from 15 studies to examine depressive symptoms and quality of life (QoL) in this understudied population. STUDY AIMS/OBJECTIVE:(1) describe sociodemographic characteristics and (2) analyze sociodemographic variables and depressive symptoms as predictors of QoL of YAWE. METHODS:The MEW-DB was queried for all young adults ages 18-29 with completed standardized psychosocial measures of QoL, depressive symptoms, and sociodemographic information. Of 418 young adults, n = 237 from 11 studies had QoL data and n = 85 had complete data for regression modeling. Mood items were categorized into cognitive (COG) and somatic (SOM) phenotypes of depression symptoms. Multivariable regression models examined individual relationships for suicidality; COG; SOM; and total depression symptom score on QoL, adjusting for sociodemographic attributes. RESULTS:Total depression symptoms, suicidality, COG symptoms, and SOM symptoms were significantly associated with QoL. Total depression symptom score explained the most variance in QoL. CONCLUSIONS:This novel analysis leveraged aggregated data focused on epilepsy self-management. YAWE have not been well-studied as a stand-alone group. Separating the effects of cognitive and somatic symptoms of depression does not appear to be meaningful for understanding QoL as the effects of cognitive and somatic symptoms of depression appear similar. Future research needs to examine cognitive and somatic effects in greater detail to understand effects on QoL and other health-related outcomes.

AIM/OBJECTIVE:To investigate how psychosocial stress contributes to accelerated thrombosis, focusing on platelet activation and hyperreactivity. The specific objective was to identify novel platelet regulators involved in stress-mediated thrombosis, with a particular emphasis on the tetraspanin CD37. METHODS AND RESULTS/RESULTS:To explore how stress contributes to platelet hyperreactivity, platelets were isolated from (1) mice that experienced chronic variable stress and stress-free controls (n=8/group) and (2) human subjects with self-reported high and no stress levels (n=18/group), followed by RNA-sequencing. By comparing mutually expressed transcripts, a subset of genes differentially expressed following psychosocial stress was identified in both human and mouse platelets. In both mice and humans, platelet CD37 positively associates with platelet aggregation responses that underlie thrombosis, with Cd37-/- platelets exhibiting impaired integrin αIIbβ3 signaling, characterized by reduced platelet fibrinogen spreading and decreased agonist-induced αIIbβ3 activation. Consistent with a role for CD37 in regulating platelet activation responses, chimeric mice that received Cd37-/- bone marrow experienced a significantly increased time to vessel occlusion in the carotid artery FeCl3 model compared to mice reconstituted with wild-type bone marrow. CD37 deficiency did not alter hemostasis, as platelet count, coagulation metrics, prothrombin time, and partial thromboplastin time did not differ in Cd37-/- mice relative to wild-type mice. Consistent with this, bleeding time did not differ between wild-type and Cd37-/- mice following tail tip transection. CONCLUSIONS:This study provides new insights into the platelet-associated mechanisms underlying stress-mediated thrombosis. Identifying CD37 as a novel regulator of platelet activation responses offers potential therapeutic targets for reducing the thrombotic risk associated with psychosocial stress. The findings also contribute to understanding how psychosocial stress accelerates thrombotic events and underscore the importance of platelet activation in this process.

AIMS/OBJECTIVE:The Managing Epilepsy Well (MEW) Network has led the development, testing and scale-up of epilepsy self-management (ESM). The MEW Integrated Database (MEW DB) is a pooled repository of archival studies that facilitates aggregate analysis. This report describes an implementation evaluation tool for ESM adopters. METHODS:Publicly available materials on program implementation, adoption and sustainability as well as readiness surveys used by the MEW Network were reviewed, as were content domains and format styles relevant to ESM implementation. Requirements for data Tiers included: 1) survey Tier should be short (≤6 items) and completed quickly (< 3 min), 2) question and response format should be consistent, 3) data elements are relevant to ESM adopters and 4) the tool should be applicable across ESM programs. Iterative review, discussion and item-ranking yielded a final set of 3 distinct data element Tiers. RESULTS:Implementation data elements assess the characteristics of organization that may be a potential ESM adopter (Tier 1), organizational readiness to ESM implementation (Tier 2) and perceptions of ESM program effects or impact by adopters at the individual and program levels (Tier 3). There are 18 data elements, 6 elements in each Tier. Organizational characteristics reflect health disparities among people with epilepsy and common comorbidities. Implementation readiness barriers include motivational factors, training and resources. Implementation experience/outcomes include perceived ESM duration, credibility, impact, likability and effectiveness. CONCLUSIONS:A brief and practical implementation evaluation tool for ESM has potential value and important clinical and policy implications in advancing care for people with epilepsy.

BACKGROUND:Women with chronic coronary disease have more frequent angina and worse health status than men, despite having less coronary artery disease (CAD). We examined whether perceived stress and depressive symptoms mediate sex differences in angina, and whether this relationship differs in the setting of obstructive CAD or ischemia with no obstructive coronary artery disease (INOCA). METHODS:We analyzed the association between sex, stress (Perceived Stress Scale-4) and depressive symptoms (Patient Health Questionnaire-8) on angina-related health status (Seattle Angina Questionnaire [SAQ]) at enrollment in the ISCHEMIA (International Study of Comparative Health Effectiveness With Medical and Invasive Approaches) trial and CIAO-ISCHEMIA (Changes in Ischemia and Angina Over 1 Year Among ISCHEMIA Trial Screen Failures With No Obstructive CAD on Coronary CT [Computed Tomography] Angiography) ancillary study. RESULTS:=0.012). Higher stress and depressive symptoms were associated with worse angina in both cohorts. Female sex, Perceived Stress Scale-4 score, and Patient Health Questionnaire-8 score were each independently associated with lower SAQ summary score, but CAD versus INOCA cohort was not. There was no interaction between sex and stress (-0.39 [95% CI, -1.01 to 0.23]) or sex and depression (-0.00 [95% CI, -0.53 to 0.53]) on SAQ summary score. CONCLUSIONS:High stress and depressive symptoms were independently associated with worse angina and poorer health status, without interaction with sex with or without obstructive CAD. Factors other than stress or depression contribute to worse health status in women with obstructive CAD or INOCA.

BACKGROUND/UNASSIGNED:Elevated perceived stress is associated with adverse outcomes following myocardial infarction (MI) and may account for poorer recovery among women vs men. OBJECTIVES/UNASSIGNED:This randomized controlled trial tested effects of a mindfulness-based intervention on stress levels among women with MI. METHODS/UNASSIGNED:Women with elevated stress (Perceived Stress Scale [PSS-4]≥6) at least 2 months after MI were enrolled from 12 hospitals in the United States and Canada and via community advertising. Participants were randomized to a remotely delivered mindfulness intervention (MBCT-Brief) or heart disease education, both 8 weeks long. Follow-up was 6 months. Changes in stress (PSS-10; primary outcome) and secondary outcomes (depressive symptoms, anxiety, quality of life, disease-specific health status, actigraphy-assessed sleep) were compared between groups. RESULTS/UNASSIGNED: = 0.036). CONCLUSIONS/UNASSIGNED:MBCT-Brief was associated with greater 6-month reductions in stress than an active control among adherent participants. More frequent mindfulness practice was associated with greater improvements in psychological outcomes. Strategies to engage women with MI in mindfulness training and support regular home practice may enhance these effects.

BACKGROUND/UNASSIGNED:Caregiving has been associated with high blood pressure in middle-aged and older women, but this relationship is understudied among younger Black women, a population at high risk for hypertension. We examined the associations of caregiving stress and caregiving for high-needs dependents with incident hypertension among reproductive-age women in the JHS (Jackson Heart Study), a cohort of community-dwelling Black adults. METHODS/UNASSIGNED:We included 453 participants, aged 21 to 44 years, with blood pressure <140/90 mm Hg, and not taking antihypertensive medication at baseline (2000-2004). Caregiving stress over the past 12 months was assessed via a single item in the global perceived stress scale. Caregiving for a high-needs dependent status was assessed via a question on hours per week spent caregiving for children (≤5 years or disabled) or older adults. Incident hypertension was defined as systolic blood pressure ≥140 mm Hg, diastolic blood pressure ≥90 mm Hg, or self-report of taking antihypertensive medication at follow-up exams in 2005 to 2008 and 2009 to 2013. RESULTS/UNASSIGNED:Over a median follow-up of 7.4 years, 43.5% of participants developed hypertension. Participants with moderate/high versus no/low caregiving stress had a higher incidence of hypertension (51.7% versus 40.6%). Higher caregiving stress was associated with incident hypertension after adjustment for sociodemographic and clinical factors, health behaviors, and depressive symptoms (hazard ratio, 1.39 [95% CI, 1.01-1.94]). Being a caregiver for a high-needs dependent was not associated with incident hypertension (adjusted hazard ratio, 0.88 [95% CI, 0.64-1.21]). CONCLUSIONS/UNASSIGNED:Higher caregiving stress among reproductive-age Black women was associated with incident hypertension. Hypertension prevention approaches for this high-risk population may include caregiving stress management strategies.

OBJECTIVE:Residents of Puerto Rico are disproportionately exposed to social and environmental stressors (e.g., Hurricane María and the 2020 sequence of tremors) known to be associated with psychological distress. Shift-and-persist (SP), or the ability to adapt the self to stressors while preserving focus on the future, has been linked with lower psychological distress, but no study has evaluated this in Puerto Rico. This study examined the association between SP and psychological distress (including that from natural disasters) in a sample of young adults in Puerto Rico. METHODS:Data from the Puerto Rico-OUTLOOK study (18-29 y) were used. Participants (n = 1497) completed assessments between September 2020 and September 2022. SP was measured with the Chen scale and categorized into quartiles (SPQ1-SPQ4). Psychological distress included symptoms of depression (CESD-10), anxiety (STAI-10), post-traumatic stress disorder (Civilian Abbreviated Scale PTSD checklist), and ataque de nervios (an idiom of distress used by Latinx groups). Outcomes were dichotomized according to clinical cutoffs when available, otherwise used sample-based cutoffs. Two additional items assessed the perceived mental health impact of Hurricane María and the 2020 sequence of tremors (categorized as no/little impact vs. some/a lot). Adjusted prevalence ratios (PR) and their 95% confidence intervals (CI) were estimated. RESULTS:The most commonly reported psychological distress outcome was PTSD (77%). In adjusted models, compared to SP Q1, persons in SP Q2-Q4 were less likely to have elevated symptoms of depression (PR Q2 = 0.79, 95% CI = 0.72-0.85; PR Q3 = 0.65, 95% CI = 0.58-0.73; and PR Q4 = 0.41, 95% CI = 0.35-0.48), PTSD (PR Q2 = 0.92, 95% CI = 0.87-0.98; PR Q3 = 0.86, 95% CI = 0.80-0.93; and PR Q4 = 0.76, 95% CI = 0.70-0.83), anxiety (PR Q2 = 0.39, 95% CI = 0.31-0.48; PR Q3 = 0.27, 95% CI = 0.20-0.37; and PR Q4 = 0.11, 95% CI = 0.07-0.17) and experiences of ataque de nervios (PR Q2 = 0.85, 95% CI = 0.76-0.94; PR Q3 = 0.79, 95% CI = 0.70-0.90; and PR Q4 = 0.68, 95% CI = 0.60-0.78). Compared to persons in SP Q1, persons in SP Q3-Q4 were less likely to report adverse mental health impacts from Hurricane María (PR Q3 = 0.66, 95% CI = 0.55-0.79; and PR Q4 = 0.53, 95% CI = 0.44-0.65) and the 2020 sequence of tremors (PR Q3 = 0.77, 95% CI = 0.61-0.98; and PR Q4 = 0.74, 95% CI = 0.59-0.94). CONCLUSION/CONCLUSIONS:SP was associated with lower psychological distress. Studies are needed to confirm our findings and evaluate potential mechanisms of action.
