RESUMO

This is the initial report of results from the AURORA multisite longitudinal study of adverse post-traumatic neuropsychiatric sequelae (APNS) among participants seeking emergency department (ED) treatment in the aftermath of a traumatic life experience. We focus on n = 666 participants presenting to EDs following a motor vehicle collision (MVC) and examine associations of participant socio-demographic and participant-reported MVC characteristics with 8-week posttraumatic stress disorder (PTSD) adjusting for pre-MVC PTSD and mediated by peritraumatic symptoms and 2-week acute stress disorder (ASD). Peritraumatic Symptoms, ASD, and PTSD were assessed with self-report scales. Eight-week PTSD prevalence was relatively high (42.0%) and positively associated with participant sex (female), low socioeconomic status (education and income), and several self-report indicators of MVC severity. Most of these associations were entirely mediated by peritraumatic symptoms and, to a lesser degree, ASD, suggesting that the first 2 weeks after trauma may be a uniquely important time period for intervening to prevent and reduce risk of PTSD. This observation, coupled with substantial variation in the relative strength of mediating pathways across predictors, raises the possibility of diverse and potentially complex underlying biological and psychological processes that remain to be elucidated with more in-depth analyses of the rich and evolving AURORA data.

RESUMO

PURPOSE: To conduct a secondary analysis focused on health-related quality of life (HRQOL) among caregivers engaged in a 12-week complementary therapy sequential multiple assignment randomized trial (SMART) of reflexology and/or meditative practices (MP), to manage cancer patients' symptoms. METHODS: In this SMART, patient-caregiver dyads were initially randomized to 4 weeks of caregiver-delivered reflexology for the patient (N = 150), MP with the patient (N = 150), or control (N = 47). After 4 weeks, dyads with patients not improving on fatigue (non-responders, n = 69 to reflexology and n = 57 to MP) were re-randomized to continue the same therapy or add the other therapy for an additional 4 weeks. Week-12 caregiver HRQOL was measured using the Patient Reported Outcomes Measurement Information System (PROMIS) Profile-29 and the Caregiver Reaction Assessment Tool (CRAT) for caregiver burden; scores were analyzed using general linear models. RESULTS: In the comparison of 4 adaptive intervention sequences: reflexology for 8 weeks, reflexology for 4 weeks followed by MP for 4 weeks if no response to reflexology, MP for 8 weeks, and MP for 4 weeks followed by reflexology for 4 weeks if no response to MP, there were no differences in PROMIS-29 scores. However, CRAT domains of impact on schedule, family support, and finances worsened when adding reflexology after the first 4 weeks of MP. The CRAT domain of health worsened by adding either intervention compared to continuing the same one. CONCLUSIONS: Clinicians should be aware that caregiver engagement in more than one complementary therapy may increase caregiver burden in some domains but not affect other HRQOL domains.

RESUMO

BACKGROUND: Mexican-origin adults living near the U.S.-Mexico border experience unique and pervasive social and ecological stressors, including poverty, perceived discrimination, and environmental hazards, potentially contributing to the high burden of chronic disease. However, there is also evidence that residents in high-density Mexican-origin neighborhoods exhibit lower prevalence rates of disease and related mortality than those living in other areas. Understanding the factors that contribute to health resiliencies at the community scale is essential to informing the effective design of health promotion strategies. METHODS: La Vida en la Frontera is a mixed-methods participatory study linking a multi-disciplinary University of Arizona research team with Campesinos Sin Fronteras, a community-based organization founded by community health workers in San Luis, Arizona. This paper describes the current protocol for aims 2 and 3 of this multi-faceted investigation. In aim 2 a cohort of N≈300 will be recruited using door-to-door sampling of neighborhoods in San Luis and Somerton, AZ. Participants will be surveyed and undergo biomarker assessments for indicators of health and chronic stress at three time points across a year length. A subset of this cohort will be invited to participate in aim 3 where they will be interviewed to further understand mechanisms of resilience and wellbeing. DISCUSSION: This study examines objective and subjective mechanisms of the relationship between stress and health in an ecologically diverse rural community over an extended timeframe and illuminates health disparities affecting residents of this medically underserved community. Findings from this investigation directly impact the participants and community through deepening our understanding of the linkages between individual and community level stress and chronic disease risk. This innovative study utilizes a comprehensive methodology to investigate pathways of stress and chronic disease risk present at individual and community levels. We address multiple public health issues including chronic disease and mental illness risk, health related disparities among Mexican-origin people, and health protective mechanisms and behaviors.

RESUMO

Objective:This study examined associations between diet quality and disease activity in adults with rheumatoid arthritis (RA). Perceived stress was also compared to diet and disease activity. Methods: In a cross-sectional design, 50 adults with RA were recruited. The Arizona Food Frequency Questionnaire was used to measure dietary intake (four weeks) and diet quality scores were calculated with the Healthy Eating Index - 2015. Perceived stress was measured with the Perceived Stress Scale. Disease activity was measured with the Health Assessment Questionnaire-Disability Index and Pain Scale, erythrocyte sedimentation rate (ESR), high-sensitivity C-reactive protein, and Disease Activity Score Including 28 Joints-ESR. Results: Diet quality (56; SD ± 12) in participants was lower than the national mean (59). Age (p = 0.015) and gender (p = 0.003) were associated with higher diet quality. The belief that diet affects RA disease activity was reported by 44% of the participants, and these participants were significantly more likely to report dietary changes (p < 0.0001). Higher educational level (at least some college) was associated with this belief (B = -1.535, p = 0.023). Participants with lower diet quality also had significantly higher pain (B = -0.396, p = 0.022) and ESR scores (p = 0.019). Women were more likely to have higher HAQ-DI scores (B = 0.570, p = 0.001). Perceived stress was significantly associated with HAQ-DI and pain scores (B = 0.445, p = 0.001 and B = 0.289, p = 0.042, respectively). Medical cannabis was reportedly used by 8% of participants. Conclusion: In RA patients, lower diet quality may be associated with more pain and inflammation, and perceived stress may be associated with higher disability and disease activity.

RESUMO

Optimal sequencing of complementary therapies can help improve symptom management through nonpharmacological approaches. A 12-week sequential multiple assignment randomized trial comparing home-based reflexology and meditative practices on severity of fatigue and other symptoms was conducted among patients with cancer and their informal caregivers. Dyads were initially randomized to reflexology (N = 150), meditative practices (N = 150), or control (N = 47). If patient's fatigue did not improve (nonresponse) after 4 weeks of reflexology or meditative practices, the dyad was rerandomized to either add the other therapy or continue with the original therapy for weeks 5-8. Four decision rules (DRs) were compared: (1) Initiating reflexology, and if nonresponse on fatigue after 4 weeks, continue with reflexology for another 4 weeks, thus providing a higher dose; (2) Initiating reflexology, and if nonresponse on fatigue after 4 weeks, add meditative practices for the next 4 weeks; (3) Initiating meditative practices, and if nonresponse on fatigue after 4 weeks, continue meditative practices for another 4 weeks, thus providing a higher dose; and (4) Initiating meditative practices, and if nonresponse on fatigue after 4 weeks, add reflexology for the next 4 weeks. Symptoms were evaluated weekly using the M.D. Anderson Symptom Inventory (MDASI). Clinically, nurses can recommend either therapy since no differences were found among the 4 DRs, with the exception of lower severity for summed MDASI symptoms at week 8 for the use of reflexology only (DR-1) versus DR-2 (sequencing reflexology to meditative practices). Adding the other therapy for nonresponders after 4 weeks may not be warranted.

RESUMO

Adverse social conditions have been linked to a conserved transcriptional response to adversity (CTRA) in circulating leukocytes that may contribute to social gradients in disease. However, the CNS mechanisms involved remain obscure, in part because CTRA gene-expression profiles often track external social-environmental variables more closely than they do self-reported internal affective states such as stress, depression, or anxiety. This study examined the possibility that variations in patterns of natural language use might provide more sensitive indicators of the automatic threat-detection and -response systems that proximally regulate autonomic induction of the CTRA. In 22,627 audio samples of natural speech sampled from the daily interactions of 143 healthy adults, both total language output and patterns of function-word use covaried with CTRA gene expression. These language features predicted CTRA gene expression substantially better than did conventional self-report measures of stress, depression, and anxiety and did so independently of demographic and behavioral factors (age, sex, race, smoking, body mass index) and leukocyte subset distributions. This predictive relationship held when language and gene expression were sampled more than a week apart, suggesting that associations reflect stable individual differences or chronic life circumstances. Given the observed relationship between personal expression and gene expression, patterns of natural language use may provide a useful behavioral indicator of nonconsciously evaluated well-being (implicit safety vs. threat) that is distinct from conscious affective experience and more closely tracks the neurobiological processes involved in peripheral gene regulation.

RESUMO

OBJECTIVES: Research has documented increased psychological distress among adults during the 2016 U.S. presidential election; however, little is known about how major political events affect adolescents. Despite not actively participating in the election process (e.g., voting), adolescents generally, and Latino youth specifically, may experience a unique stress response during elections, particularly when perceived policy changes center on issues related to their own families' stability and well-being. METHODS: We examined 42 Latino early adolescents (Mage = 12.50 years, SD = .88; 58% male; 94% immigrant background) living in Arizona and explored their psychological and physiological responses during the 2016 U.S. presidential election. Adolescents self-reported their mood and behaviors for 5 consecutive days across election week (November 6-10, 2016): 2 days before the election, election day, and 2 days after the election. They also completed a saliva sampling protocol at waking and bedtime each day, to capture diurnal cortisol concentrations. RESULTS: Multilevel growth models were utilized to examine intraindividual changes in positive affect, negative affect, and diurnal cortisol patterns across election week. Only 2 of the participants reported supporting the winning candidate. Changes in adolescents' stress hormone concentrations were evident; increases in evening cortisol levels and flatter diurnal cortisol slopes emerged across election week. Negative affect, positive affect, and morning cortisol concentrations did not change. CONCLUSIONS: This study provides preliminary evidence that macrolevel factors, such as the recent presidential election, may relate to adolescents' daily stress physiology. Further research is needed to better understand adolescents' responses to sociopolitical change. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

RESUMO

OBJECTIVE: C-reactive protein (CRP), a marker of systemic inflammation, has been associated with psychiatric disorders including major depressive disorder (MDD) and post-traumatic stress disorder (PTSD). Some research suggests that exposure to trauma can trigger increased activity in the inflammatory system. Dissociation is associated with chronic trauma exposure and may be an important factor in understanding the risk for psychiatric outcomes associated with inflammation. The main objective of the current study was to understand how CRP was related to trauma, dissociation, PTSD and MDD in a sample of 55 traumatized African American women with type 2 diabetes mellitus recruited from an urban hospital. METHOD: High sensitivity CRP (hsCRP) was assayed through blood samples; psychiatric disorders were assessed with structured clinical interviews, dissociation was assessed with the Multiscale Dissociation Inventory, and exposure to trauma in childhood and adulthood was assessed with the Childhood Trauma Questionnaire and the Traumatic Events Inventory, respectively. RESULTS: Correlational results showed a significant association between higher concentrations of hsCRP and child abuse (p < 0.05), overall dissociation severity (p < 0.001), and PTSD symptoms (p < 0.01). ANOVA results showed significantly higher levels of hsCRP in those with current MDD, current PTSD, and remitted PTSD. A hierarchical linear regression model demonstrated a significant association between dissociation symptoms and greater hsCRP levels independent of childhood abuse, PTSD, and MDD (R2∆ = 0.11, p = 0.001) and independent of emotion dysregulation (p < 0.05). CONCLUSION: These findings suggest that dissociation symptoms among those with a history of trauma may be particularly associated with higher levels of inflammation.

RESUMO

Circulating concentrations of interleukin (IL)-6, an inflammatory biomarker widely assessed in humans to study the inflammatory response to acute psychological stress, have for decades been quantified using enzyme-linked immunosorbent assay (ELISA). However, biobehavioral researchers are increasingly using cytokine multiplex assays instead of ELISA to measure IL-6 and other cytokines. Despite this trend, multiplex assays have not been directly compared to ELISA for their ability to detect subtle stress-induced changes of IL-6. Here, we tested the prediction that a high-sensitivity multiplex assay (human Magnetic Luminex Performance Assay, R&D Systems, Minneapolis, MN) would detect changes in IL-6 as a result of acute stress challenge in a manner comparable to high-sensitivity ELISA. Blood was collected from 12 healthy adults immediately before and then 90 and 210 min after the start of the Trier Social Stress Test (TSST), an acute laboratory psychosocial stress challenge. In addition to quantifying IL-6 concentrations in plasma with both multiplex and ELISA, we also assessed concentrations of tumor necrosis factor-alpha, IL-8, IL-10, IL-5, and IL-2 with multiplex. The multiplex detected IL-6 in all samples. Concentrations strongly correlated with values determined by ELISA across all samples (r = 0.941, p < .001) as well as among samples collected at individual TSST time points. IL-6 responses to the TSST (i.e. area under the curve) captured by multiplex and ELISA were also strongly correlated (rs = 0.937, p < .001). While other cytokines were detected by multiplex, none changed as a result of TSST challenge at time points examined. These results suggest high-sensitivity magnetic multiplex assay is able to detect changes in plasma concentrations of IL-6 as a result of acute stress in humans.

RESUMO

OBJECTIVE: Breast cancer diagnosis and treatment negatively affect quality of life for survivors and their family caregivers. The stress process model has been useful for describing the cascade of social and psychological experiences that culminate in degraded quality of life for both survivors and their family caregivers. This study is designed to test theoretically specified predictors of negative psychosocial outcomes in a dyadic context. METHODS: Participants were 230 dyads composed of Latinas recently diagnosed with breast cancer and their primary family caregiver, who completed measures of socioeconomic status, stress, family conflict, depression, and anxiety. Data were analyzed following the Actor-Partner Interdependence Mediation Model in structural equation modeling. RESULTS: For both survivors and caregivers, there were significant direct and indirect actor effects (through family conflict) of perceived stress on depression and anxiety. Several indirect partner effects were also evident in this sample. Specifically, caregivers' stress was predictive of survivors' depression and anxiety through survivors' increased perceptions of family conflict. CONCLUSIONS: As predicted by the stress process model, stress and family conflict were predictive of psychological distress in breast cancer survivors and their family caregivers. Significant partner effects in the Actor-Partner Interdependence Mediation Model suggest that there are some dyadic influences, particularly from caregivers' stress to survivors' perceptions of exacerbated family conflict. These findings show how strained family relationships can aggravate the well-being of cancer survivors and their family caregivers through this challenging experience.

RESUMO

In this in-progress sequential multiple assignment randomized trial (SMART), dyads of solid tumor cancer patients and their caregivers are initially randomized to 4 weeks of reflexology or meditative (mindfulness) practices provided by/with their caregiver in the patient's home or to a control group. After 4 weeks, intervention group dyads in which patients do not show improvement in fatigue (non-responders) are re-randomized to either receive additional time with the same therapy during weeks 5-8 or to add the other therapy. The aims are (1) to compare reflexology and meditative practices groups during weeks 1-4 on patients' fatigue severity, summed symptom inventory score, depressive symptoms, and anxiety, so as to determine the relative effectiveness of these therapies and the characteristics of responders and non-responders to each therapy. (2) Among reflexology non-responders based on fatigue score at week 4, to determine patient symptom outcomes when meditative practices are added during weeks 5-8, versus continuing with reflexology alone. (3) Among meditative practices non-responders based on fatigue score at week 4, to determine patient symptom outcomes when reflexology is added during weeks 5-8, versus continuing with meditative practices alone. (4) To compare improvements in patient symptom outcomes among the three groups created by the first randomization. (5) To explore which dyadic characteristics are associated with optimal patient symptom outcomes, to determine tailoring variables for decision rules of future interventions. The trial has a target of 331 dyads post-attrition and has 150 dyads enrolled. We are overcoming challenges with dyadic recruitment and retention while maintaining fidelity.

RESUMO

OBJECTIVES: Young women have poorer prognosis after myocardial infarction (MI) and a higher rate of mental stress-induced ischemia compared with similarly aged men. A higher inflammatory status may help explain these sex differences. METHODS: We examined 98 patients (49 women and 49 men) age 18-59years with recent MI (past 6months). Women and men were matched for age, type of MI, and time since MI. Interleukin 6 (IL-6) concentrations were measured at baseline, after mental stress using a speech task, and after exercise/pharmacologic stress (60 and 90min). Depressive symptoms were measured with the Beck Depression Inventory (BDI-II) and angiographic coronary artery disease (CAD) severity was quantified with the Gensini score. Single-photon emission computed tomography (SPECT) was used to obtain a computerized measurement of stress-induced ischemia (summed difference score, or SDS) and determine whether severity of stress-induced ischemia affects the inflammatory response to stress. Analysis was stratified by the median age of 50. Geometric mean concentrations of IL-6 were obtained from general linear regression models. RESULTS: In both age groups, women had less angiographic CAD and a similar level of conventional risk factors compared with men. Despite this, baseline IL-6 geometric means before both mental and physical stress were twice as high in women ⩽50years of age compared to age-matched men (3.8 vs. 1.8pg/mL, p=0.001, across both conditions), while they were similar in women and men age >50years (2.3 vs. 2.2pg/mL, p=0.83). After mental stress, IL-6 concentrations increased in both women and men in a similar fashion and remained twice as high in women ⩽50years than men at both 60min (5.4 vs. 2.6pg/mL, p=0.002) and 90min (5.9 vs. 3.4pg/mL, p=0.01). No significant difference was found between women and men >50years of age at any time point after mental stress. Results were similar for physical stress. After accounting for SDS, IL-6 concentrations in young women remained higher after both mental and physical stress. Baseline IL-6 concentrations were not significantly related to inducible ischemia. CONCLUSIONS: After MI, young women aged 50years or younger, compared with age-matched men, have remarkably higher concentrations of inflammation at baseline and after both mental and physical stress, with a similar inflammatory response to both stressors. Sustained concentrations of inflammation in young women, not their response to stress, may contribute to their adverse outcomes post-MI.

RESUMO

Childhood maltreatment is likely to influence fundamental biological processes and engrave long-lasting epigenetic marks, leading to adverse health outcomes in adulthood. We aimed to elucidate the impact of different early environment on disease-related genome-wide gene expression and DNA methylation in peripheral blood cells in patients with posttraumatic stress disorder (PTSD). Compared with the same trauma-exposed controls (n = 108), gene-expression profiles of PTSD patients with similar clinical symptoms and matched adult trauma exposure but different childhood adverse events (n = 32 and 29) were almost completely nonoverlapping (98%). These differences on the level of individual transcripts were paralleled by the enrichment of several distinct biological networks between the groups. Moreover, these gene-expression changes were accompanied and likely mediated by changes in DNA methylation in the same loci to a much larger proportion in the childhood abuse (69%) vs. the non-child abuse-only group (34%). This study is unique in providing genome-wide evidence of distinct biological modifications in PTSD in the presence or absence of exposure to childhood abuse. The findings that nonoverlapping biological pathways seem to be affected in the two PTSD groups and that changes in DNA methylation appear to have a much greater impact in the childhood-abuse group might reflect differences in the pathophysiology of PTSD, in dependence of exposure to childhood maltreatment. These results contribute to a better understanding of the extent of influence of differences in trauma exposure on pathophysiological processes in stress-related psychiatric disorders and may have implications for personalized medicine.

RESUMO

C-reactive protein (CRP), a marker of systemic inflammation, has been associated with major depressive disorder (MDD) and posttraumatic stress disorder (PTSD). Emotion dysregulation is a transdiagnostic risk factor for many psychological disorders associated with chronic inflammatory state. The objective of this study was to determine whether inflammation is associated with emotion dysregulation in women with type 2 diabetes mellitus (T2DM). We examined associations between trauma exposure, MDD, PTSD, emotion dysregulation, and CRP among 40 African-American women with T2DM recruited from an urban hospital. Emotion dysregulation was measured using the Difficulties in Emotion Regulation Scale. PTSD and MDD were measured with structured clinical interviews. Child abuse and lifetime trauma load were also assessed. Analyses showed that both emotion dysregulation and current MDD were significantly associated with higher levels of CRP (p < 0.01). Current PTSD was not significantly related to CRP. In a regression model, emotion dysregulation was significantly associated with higher CRP (p < 0.001) independent of body mass index, trauma exposure, and MDD diagnosis. These findings suggest that emotion dysregulation may be an important risk factor for chronic inflammation beyond already known risk factors among women with T2DM, though a causal relationship cannot be determined from this study.

RESUMO

Clinical case reports and prospective trials have demonstrated a reproducible benefit of hypothalamic-pituitary-adrenal (HPA) axis modulation on the rate of recovery from acute inflammatory central nervous system (CNS) demyelination. As a result, corticosteroid preparations and adrenocorticotrophic hormones are the current mainstays of therapy for the treatment of acute optic neuritis (AON) and acute demyelination in multiple sclerosis.Despite facilitating the pace of recovery, HPA axis modulation and corticosteroids have failed to demonstrate long-term benefit on functional recovery. After AON, patients frequently report visual problems, motion perception difficulties and abnormal depth perception despite 'normal' (20/20) vision. In light of this disparity, the efficacy of these and other therapies for acute demyelination require re-evaluation using modern, high-precision paraclinical tools capable of monitoring tissue injury.In no arena is this more amenable than AON, where a new array of tools in retinal imaging and electrophysiology has advanced our ability to measure the anatomic and functional consequences of optic nerve injury. As a result, AON provides a unique clinical model for evaluating the treatment response of the derivative elements of acute inflammatory CNS injury: demyelination, axonal injury and neuronal degeneration.In this article, we examine current thinking on the mechanisms of immune injury in AON, discuss novel technologies for the assessment of optic nerve structure and function, and assess current and future treatment modalities. The primary aim is to develop a framework for rigorously evaluating interventions in AON and to assess their ability to preserve tissue architecture, re-establish normal physiology and restore optimal neurological function.

RESUMO

PURPOSE: This study assessed the feasibility of a meditation-based program called Cognitively-Based Compassion Training (CBCT) with breast cancer survivors. Enrollment and participant satisfaction with a novel intervention, adherence to program requirements, and differences between the intervention group and wait list controls on self-report measures were also assessed. Additionally, cortisol, a stress-related endocrine biomarker, was assessed. METHODS: Participants (n = 33) were randomly assigned to CBCT or the wait list. CBCT provided eight weekly, 2-h classes and a "booster" CBCT session 4 weeks later. CBCT participants were expected to attend classes and meditate between classes at least three times per week. Pre-/post-intervention and follow-up questionnaires measured symptom change (depression, intrusive thoughts, perceived stress, fear of cancer recurrence, fatigue/vitality, loneliness, and quality of life). Saliva samples were collected at the same periods to assess the slope of diurnal cortisol activity. RESULTS: Enrollment, class attendance, home practice time, and patient satisfaction exceeded expectations. Compared to controls, post-intervention, the CBCT group showed suggestions of significant improvements in depression, avoidance of intrusive thoughts, functional impairment associated with fear of recurrence, mindfulness, and vitality/fatigue. At follow-up, less perceived stress and higher mindfulness were also significant in the CBCT group. No significant changes were observed on any other measure including diurnal cortisol activity. CONCLUSIONS: Within the limits of a pilot feasibility study, results suggest that CBCT is a feasible and highly satisfactory intervention potentially beneficial for the psychological well-being of breast cancer survivors. However, more comprehensive trials are needed to provide systematic evidence. RELEVANCE: CBCT may be very beneficial for improving depression and enhancing well-being during breast cancer survivorship.

RESUMO

Inflammation has been associated with fatigue during and after various types of breast cancer treatments. We examined whether prior chemotherapy was associated with DNA methylation patterns that could explain persisting inflammation and/or fatigue in women treated for breast cancer. Prior to breast radiation therapy, DNA was extracted from peripheral blood mononuclear cells (PBMCs) of 61 Stage 0-IIIA breast cancer patients who had received partial mastectomy with or without chemotherapy. DNA methylation was assessed at >485,000 CpG sites across the genome along with fatigue and plasma inflammatory markers previously associated with fatigue. Compared to non-chemotherapy-treated, women who had received chemotherapy exhibited significantly decreased methylation at eight CpG sites (p<1.03×10(-7)) including four in exon 11 of transmembrane protein 49 (TMEM49), which demonstrated the largest decreases in methylation. Lower methylation at each identified CpG site was associated with increased plasma soluble tumor necrosis factor receptor 2 (sTNFR2) and interleukin (IL)-6 and mediated the relationship between chemotherapy and increases in these inflammatory biomarkers adjusting for multiple clinical and treatment characteristics. sTNFR2, but not CpG methylation status, was correlated with fatigue. Six months after breast radiation therapy, DNA methylation, inflammatory biomarkers and fatigue assessments were repeated in a subset of subjects (N=39). Reduced methylation in 4 of the 8 identified CpG sites was still observed in chemotherapy versus non-chemotherapy-treated patients, albeit with some decay indicating the dynamic and potentially reversible nature of the changes. Reduced methylation in these 4 CpG sites also continued to correlate with either increased sTNFR2 or IL-6, but not fatigue. In conclusion, prior chemotherapy treatment was associated with decreased methylation of CpG sites in DNA from PBMCs of breast cancer patients, which correlated with increased inflammatory markers prior to and 6months after radiation therapy. Persisting epigenetic changes secondary to chemotherapy may be one factor that contributes to inflammation and its consequences including cancer-related fatigue in vulnerable breast cancer patients.

RESUMO

INTRODUCTION: Puerto Rico is a territory of the United States, making Puerto Ricans vulnerable to damaging colonial policy. The purpose of this article is to utilize the socioecological model (SEM) to evaluate how the Jones Act impacted Puerto Rico after Hurricane María, examining colonialist policy as a social determinant of health (SDOH) in Puerto Rico. METHODS: Levels of the SEM used in this examination included: individual, institutional, community, policy, and context. RESULTS: Evaluation of the Jones Act using the model demonstrated relationships between all socioecological levels. The Jones Act caused delays and increased prices for goods needed to rebuild community utility infrastructure, which led to extended closures of institutions like workplaces, schools, and hospitals, and ultimately contributed to increased acute and chronic physical and mental illness among Puerto Ricans. DISCUSSION: This evaluation establishes that colonialist policy negatively impacts the health of Puerto Ricans, positioning colonialism as an SDOH.

RESUMO

BACKGROUND: The health and well-being of children in foster care are of high concern. A resource with which to disrupt maladaptation and promote healing are positive relationships among children and caregivers within the foster home. The research question was: Can an online intervention improve family hardiness and sibling relationships within foster care families? OBJECTIVES: To: (1) establish feasibility and acceptability of an online behavioral intervention within the foster family, (2) explore the effects of the intervention on relational quality outcomes, and (3) decompose the mechanisms driving improved family hardiness through mediation analysis. PARTICIPANTS AND SETTING: 95 currently fostering families across the US, participated in a 4-week, online, self-paced, behavioral intervention with an emphasis on the relationship between children residing in the home. METHODS: We employed a randomized control trial design with multiple regression analysis. Stress and relational quality outcomes were measured through psychometrically validated questionnaires on family hardiness, preparedness, and sibling relationships. RESULTS: Significant increase in family hardiness (Cohen's d = 0.97, p < 0.001) were found compared to the control group. Measures of a positive sibling relationship score increased significantly in the intervention group (d = 0.76, p < 0.002), mediating 32 % of the total effect in hardiness score. Sibling relationship served as a mediator for increasing indicators of family hardiness. CONCLUSIONS: Providing families the sibling-inclusive intervention caused an increase in positive indicators of sibling relationship and overall family hardiness. Researchers should consider the implications of supporting foster siblings and the affects their inclusion may have on outcomes for children in foster care.

RESUMO

BACKGROUND: There are few studies that examine relationships between cognitive function, illness perceptions, and medication adherence after heart transplantation, limiting the development of effective adherence-promoting interventions. OBJECTIVE: The purpose of this study was to describe relationships between cognitive function, illness perceptions, and medication adherence among heart transplant recipients. METHODS: A cross-sectional, observational design was used. Measures included the telephone-Montreal Cognitive Assessment (t-MoCA©), Patient Health Questionnaire-9, Brief Test of Adult Cognition by Telephone, Basel Assessment of Adherence to Immunosuppressive Medications Scale, and the Brief Illness Perceptions Questionnaire. Descriptive statistics, point-biserial correlations, Pearson's correlations, and logistic regression were used to describe relationships. RESULTS: Of the 35 participants (mean age: 61 years [SD: 10.3], 71.4% male, 71.4% white), 31.4% (n = 11) were classified as nonadherent to their immunosuppression medications. Higher immediate word recall, indicating better episodic memory (memory for autobiographical and recent events), and higher illness coherence scores were associated with not missing doses of medication. Higher t-MoCA© total scores, indicating normal cognitive function, and lower depression scores were associated with taking medications on time. More than 22% (n = 8) of participants scored less than 19 on the t-MoCA©, an indication of mild cognitive impairment. CONCLUSION: Cognitive impairment may be more common among heart transplant recipients than what is currently recognized, and specific domains of cognitive function were related to medication adherence after transplantation in this study. Future studies should include longitudinal evaluations of cognitive function, depression, and medication adherence. Consideration of these relationships is needed when designing adherence-promoting interventions for this population.
