Experiences of Stigma and Discrimination Compounded by Intersecting Identities among Individuals Receiving Medication for Opioid Use Disorder.

Stigma and discrimination create barriers to care among people receiving medication for opioid use disorder (MOUD). We report qualitative findings from a mixed methods study guided by three aims: to explore (1) intersecting identities of people receiving MOUD (2) how individuals experience stigma and discrimination and (3) helpful resources in addressing cumulative experiences of multiple forms of disadvantage. We conducted interviews with 25 individuals in three treatment centers in the Northeast United States and identified six themes: (1) Living with multiple socially marginalized identities and addiction; (2) Loss; (3) "It's everywhere": Discrimination and stigma; (4) A "damaged" identity, (5) Positive responses to negative experiences: Facing reality and becoming accountable, and (6) Experiencing treatment and identifying supportive interventions. Findings highlight the complexity of intersecting, marginalized social positions. Future work should look beyond one-size-fits-all approaches to care and recognize individual vulnerabilities and strengths for improving outcomes among those experiencing OUD.

Sociodemographic correlates of late HIV diagnosis among men who have sex with men (MSM) in Ghana.

Timely HIV diagnosis and medical engagement are crucial for effective viral load suppression and treatment as prevention. However, significant delays persist, particularly in Africa, including Ghana. This study focused on Ghanaian men whose route of exposure to HIV was through same-gender sexual contact (MSM), a group disproportionately impacted by HIV. Using structured surveys, we investigated the sociodemographic factors associated with late HIV diagnosis, a topic with limited existing research. Results indicate that older age groups were associated with an increased risk of late diagnosis compared to the 18-24 age group. Among the demographic variables studied, only age showed a consistent association with late HIV diagnosis. This study underscores the importance of targeted interventions to address HIV diagnosis disparities among MSM in Ghana, particularly for older age groups. The findings emphasize the need for tailored interventions addressing age-related disparities in timely diagnosis and engagement with medical services among this population. Such interventions can play a crucial role in reducing the burden of HIV within this community and fostering improved public health outcomes.

Investigating brain dynamics and their association with cognitive control in opioid use disorder using naturalistic and drug cue paradigms.

Objectives: Opioid use disorder (OUD) impacts millions of people worldwide. The prevalence and debilitating effects of OUD present a pressing need to understand its neural mechanisms to provide more targeted interventions. Prior studies have linked altered functioning in large-scale brain networks with clinical symptoms and outcomes in OUD. However, these investigations often do not consider how brain responses change over time. Time-varying brain network engagement can convey clinically relevant information not captured by static brain measures. Methods: We investigated brain dynamic alterations in individuals with OUD by applying a new multivariate computational framework to movie-watching (i.e., naturalistic; N=76) and task-based (N=70) fMRI. We further probed the associations between cognitive control and brain dynamics during a separate drug cue paradigm in individuals with OUD. Results: Compared to healthy controls (N=97), individuals with OUD showed decreased variability in the engagement of recurring brain states during movie-watching. We also found that worse cognitive control was linked to decreased variability during the rest period when no opioid-related stimuli were present. Conclusions: These findings suggest that individuals with OUD may experience greater difficulty in effectively engaging brain networks in response to evolving internal or external demands. Such inflexibility may contribute to aberrant response inhibition and biased attention toward opioid-related stimuli, two hallmark characteristics of OUD. By incorporating temporal information, the current study introduces novel information about how brain dynamics are altered in individuals with OUD and their behavioral implications.

Focus Group Study of Heart Failure Nurses' Perceptions of the Feasibility of Cognitive Behavioral Therapy for Insomnia.

BACKGROUND: People with heart failure (HF) often report insomnia with daytime consequences, including fatigue and decreased functional performance. Cognitive behavioral therapy for insomnia is an efficacious treatment, but few have access because of a shortage of trained sleep specialists. Access may be improved by offering it where people with HF receive care. OBJECTIVES: The purpose of this study was to explore the perceptions of nurses who specialize in HF regarding the value of cognitive behavioral therapy for insomnia to their patients, the feasibility of offering it in HF clinical settings, its delivery by nurses, and preferences for modes of delivery. METHODS: We used a descriptive qualitative study design. We recruited focus group participants via e-mail to American Association of Heart Failure Nurses members and through requests for nurse collaborators to distribute within their networks. We conducted focus groups via Zoom. After describing cognitive behavioral therapy for insomnia and its efficacy for people with HF, we elicited perceptions about its value if provided in the HF outpatient clinical setting, facilitators and barriers to implementation, and other ways to increase access. We audio-recorded and transcribed the discussions. Two researchers coded the data and performed thematic analysis. RESULTS: Four focus groups included 23 registered nurses and advanced practice nurses employed in outpatient HF clinics. We identified five themes: "Insomnia Overlooked," "Cognitive Behavioral Therapy for Insomnia Works," "Nurses' Role," "Barriers and Supports," and "Modes of Delivery." Nurses endorsed the importance of insomnia to people with HF and the value of providing cognitive behavioral therapy. They expressed interest in evaluating and addressing sleep, the need for increased resources to address it, and multiple modes of delivery. All nurses believed they had a role in promoting sleep health but differed in their views about providing cognitive behavioral therapy for insomnia. DISCUSSION: Nurses specializing in HF support the implementation of cognitive behavioral therapy for insomnia. Implementation studies are needed to identify effective methods to increase access to this efficacious treatment in outpatient HF clinical settings, including support and training for nurses who are interested and able to deliver it.

"It's all connected:" A mixed methods study of insomnia, stigma, and discrimination among individuals on medication for opioid use disorder.

OBJECTIVES: Insomnia is one of the most common sleep disorders among those with opioid use disorder (OUD), including those on medication for OUD. There is a dearth of literature exploring the role of social stressors on sleep outcomes among this group. The purpose of this study was to explore the association between OUD-related stigma and intersectional discrimination with insomnia among individuals on medication for OUD. METHODS: Participants were recruited from treatment clinics in the Northeast United States. Using a convergent mixed-methods research design, we explored associations with stigma (The Brief Opioid Stigma Scale), intersectional discrimination (Intersectional Discrimination Index), and insomnia (Insomnia Severity Index) through quantitative survey data and qualitative data from interviews for participant experiences. Data from the quantitative (n = 120) and qualitative (n = 25) components of the study were integrated for interpretation. RESULTS: Quantitative analysis indicated weak to moderate positive correlations between intersectional discrimination, and exploratory variables including pain, perceived stress, and psychological distress with insomnia severity. The qualitative analysis generated 4 main themes, which highlighted negative emotions and ruminations as factors that participants connected experiences with stigma and discrimination to poor sleep outcomes. Integration of data identified concordant and discordant findings. CONCLUSIONS: Stigma, discrimination, physical symptoms, and psychological distress appear to contribute to poor sleep outcomes among those with OUD. Future research should target maladaptive outcomes of rumination and negative emotions to improve sleep outcomes among those with OUD.

Correlates of Perceived Discrimination Related to Substance Use Disorders Among Patients in Methadone Maintenance Treatment.

This study sought to examine demographic, treatment-related, and diagnosis-related correlates of substance use disorder (SUD)-related perceived discrimination among patients receiving methadone maintenance treatment (MMT). Participants were 164 patients at nonprofit, low-barrier-to-treatment-access MMT programs. Participants completed measures of demographics, diagnosis-related characteristics (Brief Symptom Inventory (BSI-18) and Depressive Experiences Questionnaire (DEQ)), and treatment-related characteristics. Perceived discrimination was measured on a seven-point Likert-type scale ranging from 1 ("Not at all") to 7 ("Extremely") in response to the item: "I often feel discriminated against because of my substance abuse." Given the variable's distribution, a median split was used to categorize participants into "high" and "low" discrimination groups. Correlates of high and low discrimination were analyzed with bivariate and logistic regression models. Ninety-four participants (57%) reported high SUD-related perceived discrimination. Bivariate analyses identified six statistically significant correlates of SUD-related perceived discrimination (P < .05): age, race, age of onset of opioid use disorder, BSI-18 Depression, DEQ Dependency, and DEQ Self-Criticism. In the final logistic regression model, those with high (versus low) SUD-related perceived discrimination were more likely to report depressive symptoms and be self-critical. Patients in MMT with high compared to low SUD-related perceived discrimination may be more likely to report being depressed and self-critical.

Relationship Between Psychosocial Stress and Blood Pressure: The National Heart, Lung, and Blood Institute Family Heart Study.

Introduction: Various domains of psychosocial stress have been significantly related to blood pressure. However, ambiguity is present in how these relationships are defined in the literature. Objective: To add to the existing literature and examine the relationship between psychosocial stress (financial strain and job strain) and other cofactors on blood pressure. Methods: This secondary analysis is designed to analyze the relationship between levels of job and financial stress and blood pressure outcomes among participants in the National Heart, Lung, and Blood Institute (NHLBI) Family Heart Study 2004-2008. The descriptive, cross-sectional design uses data from a subset of study participants, 350 White and 195 Black (n = 545), 338 female (62%), and all aged 18-56 years. Psychosocial stress was measured using the Singh Stress Scale. Resting systolic (SBP) and diastolic (DBP) blood pressure values obtained on a stress reactivity protocol day in the primary study, as well as calculated mean arterial pressure (MAP) were used for this analysis. Multivariate linear regression analyses were used to explore the relationship between psychosocial stress and blood pressure. Results: In this young cohort, self-report of either financial strain or job strain was associated with lower blood pressure levels than those of participants who reported neither stressor. Differential sex and race effects appear to contribute to these results. Blood pressure levels were not significantly associated with self-report of both stressors. Conclusion: Understanding the effects of various forms of stress on blood pressure may inform more precise HTN risk-factor screening and interventions to improve BP management.

Adapting the Health Stigma and Discrimination Framework to understand the association between stigma and sleep deficiency: A systematic review.

OBJECTIVE: Sleep deficiency and sleep disorders disproportionally affect socially disadvantaged and marginalized individuals and groups. Recent evidence suggests that stigma, a social process characterized by labeling, stereotyping, and prejudice, is associated with sleep characteristics. PURPOSE: Guided by the Health Stigma and Discrimination Framework, the purpose of this systematic review is to describe associations between dimensions of stigma and sleep deficiency and to identify future directions for research. METHODS: We searched the OVIDPsycINFO, OVIDEMASE, OVIDMEDLINE, and CINAHL databases for empirical research studies that reported relationships between the 3 dimensions of stigma-internalized, perceived, and anticipated-and characteristics of sleep deficiency-duration, continuity/efficiency, timing, alertness/sleepiness, quality, and disorders. RESULTS: Of 1717 articles, 15 met our inclusion criteria. The most frequently assessed dimensions of stigma were internalized and perceived stigma. Characteristics of sleep deficiency were measured by self-report and included sleep quality, duration, trouble sleeping, and insomnia symptoms. We found consistent evidence that stigma, whether internalized, perceived, or anticipated, is associated with self-reported characteristics of sleep deficiency. CONCLUSIONS: This evidence base can be further strengthened with prospective studies that incorporate both multidimensional measures of stigma and objective measures of sleep characteristics. We outline research implications that can clarify underlying mechanisms and more precisely define the relationships between stigma and sleep and inform interventions to address stigma, improve sleep, and reduce the health inequities that disproportionately affect individuals from socially disadvantaged and marginalized groups.

Sleep Characteristics, Mood, Somatic Symptoms, and Self-Care Among People With Heart Failure and Insomnia.

BACKGROUND: Almost 50% of people with heart failure (HF) experience chronic insomnia and must perform self-care to manage their day-to-day healthcare needs. Understanding multifactorial influences on self-care, including demographic, clinical, and sleep characteristics, and mood and somatic symptoms will help identify people at highest risk for poor self-care. However, past research focused only on the associations of single symptoms and self-care. Multivariate approaches are needed to account for the synergistic associations of self-care with sleep, mood, and somatic symptoms among people with HF. OBJECTIVES: The aims of the study were to (a) evaluate the levels of self-care maintenance and self-care confidence among people with stable HF and chronic insomnia; (b) identify the clinical and demographic correlates of self-care maintenance and confidence among people with stable HF and chronic insomnia; and (c) identify the associations between sleep characteristics, mood and somatic symptoms, and self-care maintenance and confidence among people with stable HF and chronic insomnia. METHODS: We utilized a cross-sectional design with 195 adult participants who had chronic HF and insomnia. We assessed for symptoms of anxiety; depression; dyspnea; fatigue; stress; insomnia severity; and sleep disturbance, impairment, and quality. Self-care was measured using the Self-Care for Heart Failure Index v6.2. We used generalized linear models to test the associations between the demographic and clinical factors and self-care maintenance and confidence; exploratory and confirmatory factor analysis to identify the factor structure underlying the symptoms; and structural equation modeling to test the combined associations of the demographic and clinical factors and latent factors with self-care maintenance and confidence. RESULTS: Self-care maintenance, confidence, and management were inadequate in most participants. We identified three latent factors among the nine symptoms: "sleep characteristics," "mood," and "somatic symptoms." In the structural equation model, "sleep characteristics," White race, and having a left ventricular ejection fraction of <45 were associated with self-care maintenance. Age was negatively associated with self-care confidence. DISCUSSION: Poor sleep characteristics negatively influence the ability of people with HF and insomnia to perform self-care behaviors. Knowledge of the associations among age, left ventricular ejection fraction, and race with self-care will help clinicians and future researchers identify those at risk for poor self-care.

Cognitive behavioral therapy for insomnia has sustained effects on insomnia, fatigue, and function among people with chronic heart failure and insomnia: the HeartSleep Study.

STUDY OBJECTIVES: Insomnia is common among adults with chronic heart failure (HF) and associated with daytime symptoms and decrements in function. The purpose of this randomized controlled trial (RCT) was to evaluate the sustained effects over one year of CBT-I (Healthy Sleep: HS) compared with HF self-management education (Healthy Hearts; attention control: HH) on insomnia severity, sleep characteristics, symptoms, and function among people with stable HF. The primary outcomes were insomnia severity, actigraph-recorded sleep efficiency, and fatigue. METHODS: We randomized adults with stable HF with preserved or reduced ejection fraction who had at least mild insomnia (Insomnia severity index >7) in groups to HS or HH (4 sessions/8 weeks). We obtained wrist actigraphy and measured insomnia severity, self-reported sleep characteristics, symptoms (fatigue, excessive daytime sleepiness, anxiety, depression), and six-minute walk distance at baseline, within one month of treatment, and at 6 and 12 months. We used general linear mixed models (GLMM) and generalized estimating equations (GEE) to evaluate the effects. RESULTS: The sample included 175 participants (M age = 63 ± 12.9 years; 43% women; 18% Black; 68% New York Heart Association Class II or II; 33%; LVEF < 45%) randomized to HS (n = 91) or HH (n = 84). HS had sustained effects on insomnia severity, sleep quality, self-reported sleep latency and efficiency, fatigue, excessive daytime sleepiness, and six-minute walk distance at 12 months. CONCLUSIONS: CBT-I produced sustained improvements in insomnia, fatigue, daytime sleepiness, and objectively measured physical function among adults with chronic HF, compared with a robust HF self-management program that included sleep hygiene education.

A Longitudinal Epigenetic Aging and Leukocyte Analysis of Simulated Space Travel: The Mars-500 Mission.

Astronauts undertaking long-duration space missions may be vulnerable to unique stressors that can impact human aging. Nevertheless, few studies have examined the relationship of mission duration with DNA-methylation-based biomarkers of aging in astronauts. Using data from the six participants of the Mars-500 mission, a high-fidelity 520-day ground simulation experiment, we tested relationships of mission duration with five longitudinally measured blood DNA-methylation-based metrics: DNAmGrimAge, DNAmPhenoAge, DNA-methylation-based estimator of telomere length (DNAmTL), mitotic divisions (epigenetic mitotic clock [epiTOC2]), and pace of aging (PoA). We provide evidence that, relative to baseline, mission duration was associated with significant decreases in epigenetic aging. However, only decreases in DNAmPhenoAge remained significant 7 days post-mission. We also observed significant changes in estimated proportions of plasmablasts, CD4T, CD8 naive, and natural killer (NK) cells. Only decreases in NK cells remained significant post-mission. If confirmed more broadly, these findings contribute insights to improve the understanding of the biological aging implications for individuals experiencing long-duration space travel.
