RESUMEN

Amigas Latinas Motivando el Alma is a community-based intervention designed to increase social support and coping strategies among Latina immigrant women at risk for depression and anxiety. To assess satisfaction and perceived efficacy of the intervention, we conducted interviews with 32 participants that received the intervention in-person and online. Participants across both modalities found the program supportive in maintaining their mental health. They learned stress management techniques and found the support from facilitators and other participants helpful. Those receiving the intervention in-person were able to connect with other participants more easily than those that received it online. Those receiving it online noted distractions at home that made it challenging to fully engage. Community-based interventions that promote coping strategies and social support are a promising strategy for addressing mental health disparities among Latina immigrant women.TRN: NCT03749278, date of registration: November 21, 2018.

RESUMEN

Interoception, the representation of the body's internal state, plays a central role in emotion, motivation and wellbeing. Interoceptive sensibility, the ability to engage in sustained interoceptive awareness, is particularly relevant for mental health but is exclusively measured via self-report, without methods for objective measurement. We used machine learning to classify interoceptive sensibility by contrasting using data from a randomized control trial of interoceptive training, with functional magnetic resonance imaging assessment before and after an 8-week intervention (N = 44 scans). The neuroimaging paradigm manipulated attention targets (breath vs. visual stimuli) and reporting demands (active reporting vs. passive monitoring). Machine learning achieved high accuracy in distinguishing between interoceptive and exteroceptive attention, both for within-session classification (~80% accuracy) and out-of-sample classification (~70% accuracy), revealing the reliability of the predictions. We then explored the classifier potential for 'reading out' mental states in a 3-min sustained interoceptive attention task. Participants were classified as actively engaged about half of the time, during which interoceptive training enhanced their ability to sustain interoceptive attention. These findings demonstrate that interoceptive and exteroceptive attention is distinguishable at the neural level; these classifiers may help to demarcate periods of interoceptive focus, with implications for developing an objective marker for interoceptive sensibility in mental health research.

RESUMEN

The opioid epidemic has greatly increased the number of pregnant women with opioid use and newborns exposed to opioids in utero. Mothers with opioid use disorder can face stigma by nurses in perinatal care settings, contributing to negative care experiences. A survey was distributed to nurses caring for mothers and newborns exposed to opioids in a large urban hospital in the Pacific Northwest United States (n = 89) from March to July 2019. Survey measures included participant characteristics, attitude toward substance use in pregnancy and postpartum (stigma, compassion satisfaction, comfort, and knowledge), and open-ended questions. Relationships among variables and questionnaire items were examined using Pearson's correlations, 2-sample t tests, and simultaneous multiple linear regression. Qualitative description was used to analyze open-ended questions. Nurses' stigma was negatively correlated with compassion satisfaction (r = -0.63), feeling knowledgeable (r = -0.36), and comfortable in providing care to this population (r = -0.44). Nurses identified defensiveness, lack of trust, and inadequate social support as key challenges in this patient population. Nurses suggested more support for mothers and nurses, increased nursing education, and clinical guidelines to improve clinical practice and foster therapeutic relationships. Findings highlight potential strategies to improve nursing care for chemically dependent mothers and their infants. These strategies may offer practical approaches to reduce stigma, develop therapeutic relationships, and improve patient outcomes.

RESUMEN

BACKGROUND: Emotion regulation is increasingly recognized as important for the prevention and treatment of substance use disorder (SUD). However, there is an identified lack of physiological indexes of emotion dysregulation in SUD treatment studies, critically needed to better understand the link between emotion regulation capacity (measured physiologically) and self-report health outcomes among individuals in SUD treatment. OBJECTIVE: To examine the association between respiratory sinus arrhythmia (RSA) and self-report health outcomes among women in SUD treatment. METHODS: This is a cross-sectional study based on baseline data from 217 women enrolled in a randomized control trial to study a mind-body intervention as an adjunct to SUD treatment. All participants were enrolled in community-based outpatient treatment. Participants were administered questionnaires to examine sample characteristics, mental health symptoms, and interoceptive awareness and mindfulness skills. RSA data was gathered as an index of emotion dysregulation. Descriptive statistics, bivariate correlations, and regression were used in the analyses. RESULTS: Findings highlight the extensive trauma histories, low SES, and the high symptoms of distress in this sample. RSA was only significantly correlated with interoceptive awareness after controlling for age and BMI. Measures of symptomatic distress and mindfulness were not correlated with RSA. Conclusions/Importance: Results provide the first evidence of RSA as an index of interoceptive awareness in this population. The inclusion of biomarkers such as RSA in SUD clinical studies may help identify individuals that are in need of targeted treatments that include interoceptive awareness training focused on improving emotion regulation.

RESUMEN

Background: Sensory information gained through interoceptive awareness may play an important role in affective behavior and successful inhibition of drug use. This study examined the immediate pre-post effects of the mind-body intervention Mindful Awareness in Body-oriented Therapy (MABT) as an adjunct to women's substance use disorder (SUD) treatment. MABT teaches interoceptive awareness skills to promote self-care and emotion regulation. Methods: Women in intensive outpatient treatment (IOP) for chemical dependency (N = 217) at 3 community clinics in the Pacific Northwest of the United States were recruited and randomly assigned to one of 3 study conditions: MABT + treatment as usual (TAU), women's health education (WHE) +TAU (active control condition), and TAU only. At baseline and 3 months post-intervention, assessments were made of interoceptive awareness skills and mindfulness, emotion regulation (self-report and psychophysiological measures), symptomatic distress (depression and trauma-related symptoms), and substance use (days abstinent) and craving. Changes in outcomes across time were assessed using multilevel mixed-effects linear regression. Results: Findings based on an intent-to-treat approach demonstrated significant improvements in interoceptive awareness and mindfulness skills, emotion dysregulation (self-report and psychophysiology), and days abstinent for women who received MABT compared with the other study groups. Additional analyses based on participants who completed the major components of MABT (at least 75% of the intervention sessions) revealed these same improvements as well as reductions in depressive symptoms and substance craving. Conclusions: Findings that interoceptive training is associated with health outcomes for women in SUD treatment are consistent with emerging neurocognitive models that link interoception to emotion regulation and to related health outcomes, providing knowledge critical to supporting and improving SUD treatment.

RESUMEN

The goal of this study was to explore potential body awareness and bodily dissociation differences between men and women with and without sexual difficulties, using the Scale of Body Connection in a sample of 909 participants. In women, bodily dissociation scores were significantly higher across all reported sexual difficulties, except in sexual pain. Women with lack of sexual interest and sexual arousal had significantly lower body awareness when compared to women without these difficulties. These findings suggest the importance of targeting body awareness and bodily dissociation in the treatment of women's sexual difficulties.

RESUMEN

After nearly a century of use in numerous munition platforms, TNT and RDX contamination has turned up largely in the environment due to ammunition manufacturing or as part of releases from low-order detonations during training activities. Although the basic knowledge governing the environmental fate of TNT and RDX are known, accurate predictions of TNT and RDX persistence in soil remain elusive, particularly given the universal heterogeneity of pedomorphic soil types. In this work, we proposed overcoming this problem by considering the environmental persistence of these munition constituents (MC) as multivariate mathematical functions over a variety of taxonomically distinct soil types, instead of a single constant or parameter of a specific absolute value. To test this idea, we conducted experiments where the disappearance kinetics of TNT and RDX were measured over a >300 h period in taxonomically distinct soils. Classical fertility-based soil measurements were log-transformed, statistically decomposed, and correlated to TNT and RDX disappearance rates (k-TNTand k-RDX) using multivariate dimension-reduction and correlation techniques. From these efforts, we generated multivariate linear functions for k parameters across different soil types based on a statistically reduced set of their chemical and physical properties: Calculations showed that the soil properties exhibited strong covariance, with a prominent latent structure emerging as the basis for relative comparisons of the samples in reduced space. Loadings describing TNT degradation were largely driven by properties associated with alkaline/calcareous soil characteristics, while the degradation of RDX was attributed to the soil organic matter content - reflective of an important soil fertility characteristic. In spite of the differing responses to the munitions, batch data suggested that the overall nutrient dynamics were consistent for each soil type, as well as readily distinguishable from the other soil types used in this study. Thus, we hypothesized that the latent structure arising from the strong covariance of full multivariate geochemical matrix describing taxonomically distinguished "soil types" may provide the means for potentially predicting complex phenomena in soils.

RESUMEN

After nearly a century of use in numerous munition platforms, TNT and RDX contamination has turned up largely in the environment due to ammunition manufacturing or as part of releases from low-order detonations during training activities. Although the basic knowledge governing the environmental fate of TNT and RDX are known, accurate predictions of TNT and RDX persistence in soil remain elusive, particularly given the universal heterogeneity of pedomorphic soil types. In this work, we proposed a new solution for modeling the sorption and persistence of these munition constituents as multivariate mathematical functions correlating soil attribute data over a variety of taxonomically distinct soil types to contaminant behavior, instead of a single constant or parameter of a specific absolute value. To test this idea, we conducted experiments measuring the sorption of TNT and RDX on taxonomically different soil types that were extensively physical and chemically characterized. Statistical decomposition of the log-transformed, and auto-scaled soil characterization data using the dimension-reduction technique PCA (principal component analysis) revealed a strong latent structure based in the multiple pairwise correlations among the soil properties. TNT and RDX sorption partitioning coefficients (KD-TNT and KD-RDX) were regressed against this latent structure using partial least squares regression (PLSR), generating a 3-factor, multivariate linear functions. Here, PLSR models predicted KD-TNT and KD-RDX values based on attributes contributing to endogenous alkaline/calcareous and soil fertility criteria, respectively, exhibited among the different soil types: We hypothesized that the latent structure arising from the strong covariance of full multivariate geochemical matrix describing taxonomically distinguished soil types may provide the means for potentially predicting complex phenomena in soils. The development of predictive multivariate models tuned to a local soil's taxonomic designation would have direct benefit to military range managers seeking to anticipate the environmental risks of training activities on impact sites.

RESUMEN

BACKGROUND: The relationships between opioid use disorder (OUD), chronic pain, and mental health distress are complex and multidirectional. The objective of this exploratory study was to examine the relationship between mental health conditions and Chronic pain severity and interference among patients stabilized on either buprenorphine or methadone. METHODS: We report baseline data from a randomized trial of a mind-body intervention conducted at 5 outpatient clinics that provided either buprenorphine or methadone treatment. Validated scales were used to measure substance use, mental health distress, and pain severity and interference. Statistical analyses examined the relationship between mental health conditions and pain severity and interference. RESULTS: Of 303 participants, 57% (n = 172) reported Chronic pain. A total of 88% (n = 268) were prescribed buprenorphine. Mental health conditions were common, with one-quarter of the sample screening positive for all 3 mental health conditions (anxiety, depression, and posttraumatic stress disorder [PTSD]). Compared to participants without Chronic pain, participants with Chronic pain were more likely to screen positive for moderate-severe anxiety (47% vs 31%); moderate-severe depression (54% vs 41%); and the combination of anxiety, depression, and PTSD (31% vs 18%). Among participants with Chronic pain, mental health conditions were associated with higher pain interference. Pain severity was higher among participants with mental health conditions, but only reached statistical significance for depression. Pain interference scores increased with a higher number of co-occurring mental health conditions. CONCLUSIONS: Among individuals stabilized on either buprenorphine or methadone, highly symptomatic and comorbid mental health distress is common and is associated with increased pain interference. Adequate screening for, and treatment of, mental health conditions in patients with OUD and Chronic pain is needed.

RESUMEN

Objective: While effective, medication for opioid use disorder (MOUD) treatment outcomes can be limited by co-occurring polysubstance use, mental health and chronic pain conditions. Interoceptive training may facilitate well-being and support medication treatment for MOUD. This study examined the pre-post effects of the mindfulness-based intervention Mindful Awareness in Body-oriented Therapy (MABT) as an adjunct to MOUD. MABT teaches interoceptive awareness skills to promote self-care and emotion regulation. Methods: People stabilized on medication for OUD (N = 303) from 6 community clinics in Northwestern United States were recruited and randomly assigned to MABT plus MOUD or MOUD only. In a mixed-methods study, we used an intent-to-treat approach to examine the proportion of days abstinent from non-prescribed opioids, and other substance use (primary outcomes) at baseline and 3 months post-intervention. Secondary outcomes included symptoms of mental health distress; emotional regulation difficulties; pain and physical symptom indicators; interoceptive awareness and mindfulness skills. Participant experience of MABT was collected through post-intervention surveys. Changes in outcomes were assessed using linear mixed models; content analysis was used to analyze the qualitative data. Results: Levels of overall substance use were low and did not differ between groups. Significant improvements in PTSD symptoms, interoceptive awareness, pain severity, pain activity interference, and physical symptom frequency were found for those who received MABT compared to MOUD only. Conclusion: In this stable MOUD population, substance use outcomes were not improved, however MABT demonstrated significant positive changes across multiple health outcomes critical for improving MOUD treatment.

RESUMEN

BACKGROUND: There is little study of lifetime trauma exposure among individuals engaged in medication treatment for opioid use disorder (MOUD). A multisite study provided the opportunity to examine the prevalence of lifetime trauma and differences by gender, PTSD status, and chronic pain. METHODS: A cross-sectional study examined baseline data from participants (N = 303) enrolled in a randomized controlled trial of a mind-body intervention as an adjunct to MOUD. All participants were stabilized on MOUD. Measures included the Trauma Life Events Questionnaire (TLEQ), the Brief Pain Inventory (BPI), and the Posttraumatic Stress Disorder Checklist (PCL-5). Analyses involved descriptive statistics, independent sample t-tests, and linear and logistic regression. RESULTS: Participants were self-identified as women (n = 157), men (n = 144), and non-binary (n = 2). Fifty-seven percent (n = 172) self-reported chronic pain, and 41% (n = 124) scored above the screening cut-off for PTSD. Women reported significantly more intimate partner violence (85%) vs 73%) and adult sexual assault (57% vs 13%), while men reported more physical assault (81% vs 61%) and witnessing trauma (66% vs 48%). Men and women experienced substantial childhood physical abuse, witnessed intimate partner violence as children, and reported an equivalent exposure to accidents as adults. The number of traumatic events predicted PTSD symptom severity and PTSD diagnostic status. Participants with chronic pain, compared to those without chronic pain, had significantly more traumatic events in childhood (85% vs 75%). CONCLUSION: The study found a high prevalence of lifetime trauma among people in MOUD. Results highlight the need for comprehensive assessment and mental health services to address trauma among those in MOUD treatment. TRIAL REGISTRATION: NCT04082637.

RESUMEN

The COVID-19 pandemic disproportionately affected racial and ethnic minority communities across the United States (U.S.). Despite the disproportionate burden of COVID-19 faced by communities of color, Black and Hispanic communities are less likely to be fully vaccinated than White non-Hispanic Persons. Health inequity and vaccine hesitancy are complex phenomena that require multilevel responses tailored to the unique needs of each community, a process that inherently necessitates a high level of community engagement in order to develop the most effective health interventions. Building on the principles of community based participatory research (CBPR) and with the support of the National Institutes of Health (NIH), Project 2VIDA! was born. A multidisciplinary collaborative of academic researchers, community members, and clinicians whose aim is to foster sustainable partnerships to reduce the burden of COVID-19 in Hispanic and Black communities across Southern California. Our model was designed to meet our community members where they were - whether on their lunch break or picking their children from school. This CBPR model has been well received by community members. Future health interventions focused on reducing health disparities should prioritize the role of the community, leverage the voices of key community partners, and be grounded in equitable power sharing.

RESUMEN

Background: To date, the United States (US) leads the world in the number of infections and deaths due to the Coronavirus Disease 2019 (COVID-19). Racial and ethnic disparities in COVID-19 morbidity and mortality are staggering. Age-adjusted data show that AA and Latino individuals have had higher rates of death over most of the pandemic and during surges. Project 2VIDA! is community-based participatory research (CBPR) that was developed to address individual, social, and contextual factors related to access and acceptance of the COVID-19 vaccine among African American and Latino communities in Southern California. This paper describes the study protocol and overarching objectives. Methods and design: Project 2VIDA! is a multilevel intervention that builds on the principals of CBPR and is designed to increase uptake of the COVID-19 vaccine among African American and Latino individuals (≥16 years and older) in San Diego County. The intervention was developed with a working group comprised of representatives from community and academia and centers on targeted COVID-19 individual awareness and education, linkage to medical and supportive services, COVID-19 community outreach and health promotion and offering the COVID-19 vaccine through community pop-up clinics. Discussion: Findings from 2VIDA! will provide data on the impact, feasibility, and acceptability of the intervention which are all crucial for the adaptation, refinement, and improvement of vaccine outreach interventions for COVID-19 and other vaccine preventable infectious diseases that severely impact African American and Latino communities.

RESUMEN

Interoception, the representation of the body's internal state, is increasingly recognized for informing subjective wellbeing and promoting regulatory behavior. However, few empirical reports characterize interoceptive neural networks, and fewer demonstrate changes to these networks in response to an efficacious intervention. Using a two-group randomized controlled trial, this pilot study explored within-participant neural plasticity in interoceptive networks following Mindful Awareness in Body-oriented Therapy (MABT). Participants (N = 22) were assigned to either 8 weeks of MABT or to a no-treatment control and completed baseline and post-intervention assessments that included subjective interoceptive awareness (MAIA) and neuroimaging of an interoceptive awareness task. MABT was uniquely associated with insula deactivation, increased functional connectivity between the dorsal attention network and the somatomotor cortex, and connectivity changes correlated positively with changes in subjective interoception. Within the MABT group, changes in subjective interoception interacted with changes in a predefined anterior cingulate seed region to predict changes in right middle insula activity, a putative primary interoceptive representation region. While the small sample size requires the replication of findings, results suggest that interoceptive training enhances sensory-prefrontal connectivity, and that such changes are commensurate with enhanced interoceptive awareness.

RESUMEN

Interoception, the representation of the body's internal state, serves as a foundation for emotion, motivation, and wellbeing. Yet despite its centrality in human experience, the neural mechanisms of interoceptive attention are poorly understood. The Interoceptive/Exteroceptive Attention Task (IEAT) is a novel neuroimaging paradigm that compares behavioral tracking of the respiratory cycle (Active Interoception) to tracking of a visual stimulus (Active Exteroception). Twenty-two healthy participants completed the IEAT during two separate scanning sessions (N = 44) as part of a randomized control trial of mindful awareness in body-oriented therapy (MABT). Compared with Active Exteroception, Active Interoception deactivated somatomotor and prefrontal regions. Greater self-reported interoceptive sensibility (MAIA scale) predicted sparing from deactivation within the anterior cingulate cortex (ACC) and left-lateralized language regions. The right insula, typically described as a primary interoceptive cortex, was only specifically implicated by its deactivation during an exogenously paced respiration condition (Active Matching) relative to self-paced Active Interoception. Psychophysiological interaction (PPI) analysis characterized Active Interoception as promoting greater ACC connectivity with lateral prefrontal and parietal regions commonly referred to as the dorsal attention network (DAN). In contrast to evidence relating accurate detection of liminal interoceptive signals such as the heartbeat to anterior insula activity, interoceptive attention toward salient signals such as the respiratory cycle may involve reduced cortical activity but greater ACC-DAN connectivity, with greater sensibility linked to reduced deactivation within the ACC and language-processing regions.

RESUMEN

BACKGROUND: Latina immigrant women are at increased risk for poor mental health. Little is known about factors associated with somatic symptoms, the physical manifestation of distress, in this population. This study examined associations between social stressors, trauma, and somatic symptoms. METHODS: This study used survey data from a community-based sample of Latina immigrant women (n = 154). We determined the frequency of somatic symptoms and used linear regressions to estimate associations of stressors and trauma with physical symptoms. RESULTS: Most participants reported mild or moderate levels of somatic symptom severity. In univariate models, all social stressors and trauma types were significantly associated with higher levels of somatic symptoms. A multivariate model suggested perceived stress was associated with increased somatic symptoms after accounting for other stressors and trauma. DISCUSSION: Future research should examine whether stress and trauma lead to higher levels of somatic symptoms among Latina immigrants.

RESUMEN

INTRODUCTION: Latina immigrants are at increased risk of depression and anxiety and limited access to mental health care. This study evaluated the effectiveness of Amigas Latinas Motivando el Alma (ALMA), a community-based intervention to reduce stress and promote mental health among Latina immigrants. METHODS: ALMA was evaluated using a delayed intervention comparison group study design. Latina immigrants (N = 226) were recruited from community organizations in King County, Washington from 2018 to 2021. Although originally developed to be delivered in-person, due to the COVID-19 pandemic the intervention was adapted mid-study to be delivered online. Participants completed surveys to assess changes in depression and anxiety post-intervention and at a two-month follow-up. We estimated generalized estimating equation models to assess differences in outcomes across groups, including stratified models for those receiving the intervention in-person or online. RESULTS: In adjusted models, participants in the intervention group had lower levels of depressive symptoms than the comparison group post-intervention (ß = -1.82, p = 0.01) and at two-month follow-up (ß = -1.52, p = 0.01). Anxiety scores decreased for both groups, and there were no significant differences post-intervention or at follow-up. In stratified models, participants in the online intervention group had lower levels of depressive (ß = -2.50, p = 0.007) and anxiety (ß = -1.86, p = 0.02) symptoms than those in the comparison group, but there were no significant differences among those that received the intervention in-person. CONCLUSIONS: Community-based interventions can be effective in preventing and reducing depressive symptoms among Latina immigrant women, even when delivered online. Further research should evaluate the ALMA intervention among larger more diverse Latina immigrant populations.

RESUMEN

Objectives: This study examined specificity in the effects of three perinatal mindfulness-based prevention programs that differed in their timing (prenatal, postpartum) and target (maternal well-being, parenting). Effects on maternal mental health (depression, anxiety, resilience), mindfulness, and observed parenting, as well as observed, physiological, and mother-report indicators of infant self-regulation, were examined. Methods: The programs were evaluated in a racially and ethnically diverse sample of first-time mothers (n = 188) living in low-income contexts using intention-to-treat analysis. Mothers were assigned to a prenatal well-being, postpartum well-being, parenting, or book control group. Multi-method assessments that included questionnaire, observational, and physiological measures were conducted at four time points: during pregnancy (T1) and when infants were 2-4 months (T2), 4-6 months (T3), and 10-12 months. Results: Compared to the postpartum intervention and control groups, the 6-week prenatal well-being intervention was related to decreases in depressive symptoms during pregnancy but not postpartum, higher maternal baseline respiratory sinus arrhythmia (RSA), fewer intrusive control behaviors, and lower infant cortisol levels in the early postpartum period. Compared to all other groups, the postpartum parenting intervention was related to decreases in maternal anxiety and increases in responsive parenting. Some differential effects across programs might be due to differences in attendance rates in the prenatal (62%) vs. postpartum (35%) groups. Conclusions: The findings suggest that brief mindfulness-based well-being and parenting preventive interventions can promote maternal and infant mental health in families living in low-income, high-stress settings, particularly if accessibility can be enhanced. Preregistration: This study is not preregistered.
