- Abstract
• Customization of a virtual environment offered interactive modes of stroke recovery education. • Virtual environment-mediated, real-time interactions among stroke survivors were achievable. • Data suggests that virtual environments are feasible and usable in the stroke population. To evaluate the feasibility and usability of stroke survivor participation in an 8-week virtual environment intervention that provides opportunities for social support exchanges, social network interactions, and recovery education. A single-group, pre- and post-test measure design was used. Descriptive statistics were used to examine enrollment and retention rates, proportion of questionnaires completed, and virtual environment process data (e.g., number of log-ins) and usability scores. Changes in pre- and post-intervention questionnaire (e.g., usability, social support, depression, anxiety, loneliness, and self-efficacy) scores were explored using Wilcoxon signed-rank tests and paired t -test. Fifteen (65 %) of the eligible stroke survivors enrolled (60 % white, 27 % black), 12 (80 %) had an ischemic stroke, ages ranged from 33 to 74 years (mean 44 years), and mean months since stroke was 33 ± 23. Retention and questionnaire completion rates were both 93 % (n = 14). Survivors logged into the virtual environment a total of 122 times, logged an average of 49 min/log-in, and 12 (80 %) attended support groups and social activities. Median usability score indicated lower than average usability. Improvement trends in social support, loneliness, and depressive symptoms were found, but significant changes in mean questionnaire scores were not found. Overall, the results suggest that using a virtual environment to foster social support exchanges, social network interactions, and recovery education after stroke is feasible. Similar to other chronic disease populations, stroke survivor adoption of a virtual environment likely requires ongoing technical assistance, repetition of instructions, and opportunities for practice to reinforce engagement.

Highlights • Inflammatory markers can distinguish bereaved spouses higher on grief severity compared with bereaved spouses with lower grief severity. • Even in a population high on depressive symptoms, there is a positive relationship between depression and inflammation. • Similar to the general population, inflammation is an important marker of elevated levels of depression among bereaved spouses. Abstract Grief is conceptualized by strong negative emotions, which include longing, sadness, and preoccupations with thoughts, recollections, and images of the spouse. In the initial months after the loss of a spouse, those who are widowed are at risk for cardiovascular problems and premature mortality. In the general population, depression is characterized by chronic low-grade inflammation, a key predictor of cardiovascular problems, morbidity, and mortality. Although depression and grief share similarities, they are distinct constructs. We aimed to identify if grief was related to inflammation among those who had a spouse recently die. We also sought to determine if those who are widowed and already experience elevated levels of depressive symptoms compared with the general population had higher levels of inflammation compared with those who are widowed who report fewer depressive symptoms. Ninety-nine recently bereaved individuals (M = 84.74 days since passing, SD = 18.17) completed a blood draw and psychological assessments. Proinflammatory T cell-derived cytokines were assessed, which included interferon gamma (IFN-γ), interleukin (IL)-6, tumor necrosis factor alpha (TNF-α), IL17-A, and IL-2. Bereaved individuals with a higher grief severity (using an established cut-score) had higher levels of the proinflammatory cytokines IFN-γ, IL-6, and TNF-α than those with less grief severity. Those who experienced higher levels of depression exhibited elevated levels of proinflammatory cytokines compared with those who had lower levels of depression (using a continuous measure of depressive symptoms, as well as an established cut score). This is the first study to demonstrate that inflammatory markers can distinguish those who are widowed based on grief severity such that those who are higher on grief severity have higher levels of inflammation compared with those who are lower on grief severity. These findings also add to the broader literature on depression and inflammation by showing that even in a population with high levels of depressive symptoms, there is a positive relationship between depression and inflammation.

The loss of a spouse is a highly stressful event that puts people at excess risk of mortality. Excess mortality among those who are widowed is highest in the first six months after the death of a spouse and decreases over time. Heart disease accounts for the largest proportion of these deaths. The psychological stress associated with stressful life events can enhance inflammation and lower heart rate variability (HRV). Both lower HRV and higher inflammation are risk factors for cardiovascular morbidity and mortality. Thirty-two recently bereaved individuals (Mean = 89.68 days since death, SD = 17.09) and 33 age-matched comparisons completed a blood draw, EKG, and self-report questionnaires. In both adjusted and unadjusted models, spousal bereavement was associated with enhanced pro-inflammatory cytokine production by in vitro lipolysaccharide-stimulated peripheral blood leukocytes. Moreover, spousal bereavement was associated with lower HRV in comparison to the comparison group. This study is the first to demonstrate that bereavement is associated with a more pronounced ex vivo cytokine production and lower HRV in a population that exclusively consisted of widows and widowers. These findings add to the growing literature revealing the mechanisms that underlie bereavement-related cardiovascular problems. Future longitudinal studies are needed to determine the temporal relation between these risks. Understanding the biological mechanisms that underlie this stressful life event could allow researchers to create therapeutic targets for interventions to reduce or prevent the toll of a “broken heart.” [ABSTRACT FROM AUTHOR]

Self-rated health (SRH) is a reliable predictor of health outcomes including morbidity and mortality. Immune dysregulation is one hypothesized mechanism underlying the association between SRH and health outcomes. Indeed, poorer SRH is associated with greater inflammation. The association between SRH and reactivation of latent herpesviruses is unknown, representing an important gap in the literature given that reactivation of latent herpesviruses leads to enhanced inflammation. The present study addressed this important gap in the literature by examining associations between SRH, inflammation (i.e., peripheral cytokines in the blood), and reactivation of latent herpesviruses among a sample of 1208 individuals participating in the Texas City Stress and Health Study. Participants completed a self-report measure of SRH and a blood draw. Results indicated that higher SRH was associated with lower reactivation of latent herpesviruses and inflammation. Moreover, reactivation of latent herpesviruses partially mediated the association between SRH and inflammation. Accordingly, findings add to our growing understanding of the association between SRH and immune dysfunction. [ABSTRACT FROM AUTHOR]

Childhood maltreatment increases the risk of depression, especially after experiencing a stressful life event, such as bereavement. Employing emotion regulation strategies can mitigate the impact childhood maltreatment has on depression later in life following the loss of a spouse. We evaluated how cognitive reappraisal and expressive suppression moderated the impact of childhood maltreatment and depressive symptoms following spousal bereavement. We examined 130 bereaved individuals 3 months after the death of a spouse, 4 months after the death of a spouse, and 6 months after the death of a spouse. We utilized a mixed model approach to test the interaction between childhood maltreatment and cognitive reappraisal and between childhood maltreatment and expressive suppression to predict depressive symptoms across 3 time points. Cognitive reappraisal moderated the relationship between childhood maltreatment and depressive symptoms (b = − 0.17, p =.003); expressive suppression did not (b = 0.06, p =.452). Participants who used less cognitive reappraisal had a positive relationship between childhood maltreatment and depressive symptoms (b = 3.27, p <.001);participants who used more cognitive reappraisal did not (b = 1.09, p =.065). Childhood maltreatment interacted with cognitive reappraisal, but not expressive suppression, to predict depressive symptoms following spousal bereavement. This study reveals how emotion regulation strategies can be utilized as a tool to buffer the impact of childhood maltreatment on mental health following a stressor later in life, which can serve as a target for future interventions for individuals experiencing a stressful life event.

Summary: Growing evidence suggests that lower subjective social status (SSS), which reflects where a person positions himself on a social ladder in relation to others, is independently related to poor health. People who rate themselves lower in status also experience more frequent stressors and report higher stress than those who rate themselves higher in status, and chronic stress can enhance an individual's response to subsequent stressors. To address whether SSS predicted stress-induced interleukin-6 (IL-6) changes, we assessed 138 healthy adults at rest and following the Trier Social Stress Test (TSST). Participants completed the TSST at two study visits, separated by 4 months. People who placed themselves lower on the social ladder had larger IL-6 responses from baseline to 45min post-stressor (p =0.01) and from baseline to 2h post-stressor (p =0.03) than those who placed themselves higher on the social ladder. Based on a ratio of subjective threat and coping ratings of the stress task, participants who viewed themselves as lower in status also tended to rate the speech task as more threatening and less manageable than those who viewed themselves as higher in status (p =0.05). These data suggest that people with lower perceived status experience greater physiological and psychological burden from brief stressors compared to those with higher perceived status. Accordingly, responses to stressors may be a possible mechanistic link among SSS, stress, and health. [Copyright &y& Elsevier]

Summary: Objective: The pain, depression, and fatigue symptom cluster is an important health concern. Loneliness is a common risk factor for these symptoms. Little is known about the physiological mechanisms linking loneliness to the symptom cluster; immune dysregulation is a promising candidate. Latent herpesvirus reactivation, which is reflected by elevated herpesvirus antibody titers, provides a window into immune dysregulation. Cytomegalovirus (CMV) and Epstein–Barr virus (EBV) are two common herpesviruses. Methods: Participants were 200 breast cancer survivors who were 2 months to 3 years post-treatment at the time of the study. They completed questionnaires and provided a blood sample that was assayed for CMV and EBV antibody titers. Results: Lonelier participants experienced more pain, depression, and fatigue than those who felt more socially connected. Lonelier participants also had higher CMV antibody titers which, in turn, were associated with higher levels of the pain, depression, and fatigue symptom cluster. Contrary to expectations, EBV antibody titers were not associated with either loneliness or the symptom cluster. Conclusions: The pain, depression, and fatigue symptom cluster is a notable clinical problem, especially among cancer survivors. Accordingly, understanding the risk factors for these symptoms is important. The current study suggests that loneliness enhances risk for immune dysregulation and the pain, depression, and fatigue symptom cluster. The present data also provide a glimpse into the pathways through which loneliness may impact health. [ABSTRACT FROM AUTHOR]

Abstract: Purpose: To identify how child maltreatment is associated with quality of life (QOL) among breast cancer survivors. Patients and methods: One hundred and thirty two women who had completed treatment for stage 0-IIIA breast cancer within the past 2years (except for tamoxifen/aromatase inhibitors) and were at least 2months post surgery, radiation, or chemotherapy completed questionnaires including the Childhood Trauma Questionnaire, the Impact of Events Scale, the Multidimensional Fatigue Symptom Inventory-Short Form (MFSI-SF) and the Fact-B breast cancer quality of life questionnaire. Results: Women who were abused or neglected as children reported more cancer-related psychological distress, more fatigue and poorer physical, emotional, functional and breast cancer-specific well-being after treatment. These relations were partially explained by the fact that breast cancer survivors reported receiving less support as adults. Conclusion: The findings suggest that child maltreatment is an important predictor of QOL among breast cancer survivors. One reason why this association exists is because those who are maltreated as children report less support as adults. A better understanding of how child maltreatment contributes to breast cancer survivor QOL will help in tailoring and, therefore, enhancing the efficacy of interventions aimed at improving QOL.

Summary: Fatigue is a notable clinical problem in cancer survivors, and understanding its pathophysiology is important. This study evaluated relationships between fatigue and both sympathetic and parasympathetic nervous system activity in breast cancer survivors. Norepinephrine and heart rate variability (HRV) were evaluated at rest, as well as during and after a standardized laboratory speech and mental arithmetic stressor. The participants, 109 women who had completed treatment for stage 0–IIIA breast cancer within the past two years, were at least two months post surgery, radiation or chemotherapy, whichever occurred last. Women who reported more fatigue had significantly higher norepinephrine and lower HRV before and after the stressor than their less fatigued counterparts. Fatigue was not related to treatment or disease variables including treatment type, cancer stage, time since diagnosis, and time since treatment. Importantly, the relationship between HRV and cancer-related fatigue was sizeable. Based on research that has demonstrated characteristic age-related HRV decrements, our findings suggest a 20-year difference between fatigued and non-fatigued cancer survivors, raising the possibility that fatigue may signify accelerated aging. Furthermore, lower HRV and elevated norepinephrine have been associated with a number of adverse health outcomes; accordingly, fatigue may also signal the need for increased vigilance to other health threats.

During pregnancy, there are significant physiological changes to support a healthy fetus. Parasympathetic activity normatively decreases across pregnancy, and psychological stress can promote even further decreased heart rate variability (HRV). This study evaluated (1) changes in vagally-mediated HRV from pregnancy to postpartum, (2) changes in vagally-mediated HRV from pregnancy to postpartum based on negative partner relationship qualities, and (3) changes in depressive symptoms from pregnancy to postpartum based on negative partner relationship qualities. 78 participants in their 3rd trimester self-reported their relationship quality with their partner at the first visit. Depressive symptoms and vagally-mediated HRV were evaluated at rest at five time points from 3rd trimester to 12 months postpartum. On average, the only significant increase in vagally-mediated HRV occurred between the 3rd trimester and 4–6 weeks postpartum. However, those who reported more negative partner relationship qualities during their 3rd trimester of pregnancy maintained lower vagally-mediated HRV levels across all of the first year postpartum and significantly lower vagally-mediated HRV at both 4 and 8 months postpartum as compared to people who reported fewer negative partner relationship qualities. Across the first year postpartum, people reporting more negative partner relationship qualities experienced more severe depressive symptoms than their counterparts with fewer negative partner relationship qualities; however, there was no difference in the rate of change of depressive symptoms across the first year postpartum based on negative partner relationship qualities. Because lower vagally-mediated HRV is associated with depressive symptoms, future work should explore the temporal relationship between vagally-mediated HRV and depressive symptoms in the postpartum period. • We assessed heart rate variability (HRV) and depressive symptoms from 3rd trimester to 12 months postpartum. • HRV increased between women's 3rd trimester of pregnancy and 4–6 weeks postpartum. • Women in more negative partner relationships during their 3rd trimester of pregnancy had lower postpartum HRV levels. • Women in more negative partner relationships had more severe postpartum depressive symptoms. • No reliable difference in the rate of change of HRV or depressive symptoms based on partner relationship qualities.

Highlights • Affective disorders impact psychological health and physical health, with increased inflammation a common co-occurring condition. • Treatments for affective disorders are not always effective, as many were developed without reference to neurobiological mechanisms. • Here, we review brain-based measures of emotion regulation strategies and their effects on mental and physical health. • Regions of prefrontal cortex play a key regulatory role in autonomic, endocrine, and attendant immunological processes. • We conclude by proposing a neuro-immuno-affective framework that targets regions of prefrontal cortex with emotion regulation skills training. Abstract In the past century, medical progress has helped increase life expectancy and improve health outcomes more generally. Despite this progress, psychiatric disorders—especially affective disorders including depressive and anxiety disorders—are quite common and have been linked to dysfunction in endocrine and immune systems. In this review, we discuss neurobiological correlates of emotion regulation strategies and their effects on mental and physical health. Some of these correlates, namely sub-regions of prefrontal cortex, also play a key regulatory role in autonomic, endocrine, and immunological processes. Given this functional overlap, we propose a novel neuro-immuno-affective framework that targets improving emotion regulation, in order to: (1) reduce negative affect associated with depressive and/or anxiety disorders; and (2) alter endocrine and immune system functioning (e.g., reduce inflammation)—via changes in activity within (and connectivity between) brain systems that support (successful) emotion regulation. We conclude by arguing that such a framework can be adapted for psychiatric treatment protocols that holistically incorporate neural and immunological biomarkers to promote mental and physical health.

Background: Fatigue is a common symptom in stressed individuals. Bereavement is a major life event that has been associated with impaired mental health. Little research has investigated the prevalence of fatigue and its inflammatory correlates in bereaved individuals.Objectives: To assess fatigue prevalence and its relationship with mental health outcomes and markers of inflammation, as indexed by C-reactive protein (CRP), interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-α) in bereaved individuals.Methods: Seventy-eight-bereaved adults were examined for fatigue (SF-36 energy/vitality scale), perceived stress (PSS), depression (CES-D), sleep quality (PSQI), pain (SF-36 pain scale), and general health (SF-36 general), and their serum levels of CRP, IL-6 and TNF-α were measured. Group differences between fatigued versus non-fatigued individuals were estimated using analysis of covariance (ANCOVA), with adjustment for body mass index (BMI).Results: Fatigued bereaved individuals (33%; SF-36 energy/vitality score 0-45) had significantly higher CRP levels (p < .05) as compared to non-fatigued bereaved individuals and reported higher levels of pain (p < .001), greater stress (p < .001), depression (p < .001), and sleeping problems (p < .001), as well as poorer social functioning (p < .001) and general health (p < .001) than those in the non-fatigued group. No group differences were found for IL-6 and TNF-α.Conclusions: Fatigued bereaved individuals showed elevated systemic inflammation as measured by CRP in comparison to non-fatigued bereaved individuals. They were also more likely to report mental health problems that co-occur with fatigue in the context of immune activation. Continued research is needed to help clarify the involvement of inflammatory markers in the development of fatigue in a larger sample of bereaved adults. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Objectives Measuring patient-reported outcomes (PROs) has become increasingly important for assessing quality of care and guiding patient management. However, PROs have yet to be integrated with traditional clinical outcomes (such as length of hospital stay), to evaluate perioperative care. This study aimed to use longitudinal PRO assessments to define the postoperative symptom recovery trajectory in patients undergoing thoracic surgery for lung cancer. Methods Newly diagnosed patients (N = 60) with stage I or II non–small cell lung cancer who underwent either standard open thoracotomy or video-assisted thoracoscopic surgery lobectomy reported multiple symptoms from before surgery to 3 months after surgery, using the MD Anderson Symptom Inventory. We conducted Kaplan–Meier analyses to determine when symptoms returned to presurgical levels and to mild-severity levels during recovery. Results The most-severe postoperative symptoms were fatigue, pain, shortness of breath, disturbed sleep, and drowsiness. The median time to return to mild symptom severity for these 5 symptoms was shorter than the time to return to baseline severity, with fatigue taking longer. Recovery from pain occurred more quickly for patients who underwent lobectomy versus thoracotomy (8 vs 18 days, respectively; P = .022). Patients who had poor preoperative performance status or comorbidities reported higher postoperative pain (all P < .05). Conclusions Assessing symptoms from the patient's perspective throughout the postoperative recovery period is an effective strategy for evaluating perioperative care. This study demonstrates that the MD Anderson Symptom Inventory is a sensitive tool for detecting symptomatic recovery, with an expected relationship among surgery type, preoperative performance status, and comorbid conditions.

Sleep problems can boost inflammation and may jeopardize interpersonal functioning, risks that may be magnified in couples. This observational study examined the effects of self-reported recent sleep duration on couples’ inflammation, inflammatory responses to a problem discussion, interpersonal behavior, and use of emotion regulation strategies (emotion expression, cognitive reappraisal) during conflict. People who slept less had higher stimulated interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) production after the marital problem discussion than those who slept more. However, using emotion expression and cognitive reappraisal strategies during conflict protected couples who slept less from inflammatory reactivity. Specifically, people’s short sleep did not relate to inflammatory increases when they expressed their own feelings more or when their partner reappraised or expressed their emotions more. When both partners slept less, couples interacted in a more hostile way than when at least one partner slept more. These data point to the combination of short sleep and marital conflict as a novel path to heightened inflammation, a risk that partners’ emotion regulation strategies may counteract. The study also highlights the role of short sleep in more negative or punishing marital behavior. [ABSTRACT FROM AUTHOR]

Hostility and adverse health outcomes are inconsistently associated in the literature. Self-regulation and cortisol secretion may play important roles in differentiating those hostile individuals who are at greater risk of negative health outcomes from those who are not. In the present study, we sought to examine if having high self-regulatory strength, as indexed by high stress-induced high-frequency heart rate variability (HF-HRV), buffered the effects of hostility on cortisol secretion. Participants ( N = 213) completed a self-report measure of hostility and measurement of HF-HRV at rest and during a social stress task. Saliva samples were collected immediately before (one sample), and over a 50 min period after (six samples), the stress task to evaluate cortisol secretion over time. Hostile individuals were less likely to demonstrate cortisol sensitivity (i.e., high change in cortisol over time) when they had high stress-induced HF-HRV. Such findings are important given that cortisol sensitivity increases risk of metabolic and inflammatory disorders via glucocorticoid resistance and inflammation. Therefore, interventions that increase stress-induced HF-HRV may reduce the impact of hostility on health outcomes. [ABSTRACT FROM AUTHOR]

Background: Depression and stress promote obesity. This study addressed the impact of daily stressors and a history of major depressive disorder (MDD) on obesity-related metabolic responses to high-fat meals. Methods: This double-blind, randomized, crossover study included serial assessments of resting energy expenditure (REE), fat and carbohydrate oxidation, triglycerides, cortisol, insulin, and glucose before and after two high-fat meals. During two separate 9.5-hour admissions, 58 healthy women (38 breast cancer survivors and 20 demographically similar control subjects), mean age 53.1 years, received either a high saturated fat meal or a high oleic sunflower oil meal. Prior day stressors were assessed by the Daily Inventory of Stressful Events. Results: Greater numbers of stressors were associated with lower postmeal REE (p = .008), lower fat oxidation (p = .04), and higher insulin (p = .01), with nonsignificant effects for cortisol and glucose. Women with prior MDD had higher cortisol (p = .008) and higher fat oxidation (p = .004), without significant effects for REE, insulin, and glucose. Women with a depression history who also had more stressors had a higher peak triglyceride response than other participants (p = .01). The only difference between meals was higher postprandial glucose following sunflower oil compared with saturated fat (p = .03). Conclusions: The cumulative 6-hour difference between one prior day stressor and no stressors translates into 435 kJ, a difference that could add almost 11 pounds per year. These findings illustrate how stress and depression alter metabolic responses to high-fat meals in ways that promote obesity. [ABSTRACT FROM AUTHOR]

Indirect fluorescence analysis (IFA), the gold standard for determining herpesvirus antibody titers, is labor-intensive and poorly suited for large population-based studies. The enzyme-linked immunosorbent assay (ELISA) is used widely for measuring antiviral antibodies but also suffers drawbacks such as reduced specificity and the qualitative nature of the results due to limited interpretation of the optical density (OD) units. This paper describes a method to titer herpesvirus antibodies using microplates coated with virally-infected cells in which a standard curve, derived from IFA-scored samples, allowed OD units to be converted into titers. A LOOKUP function was created in order to report the data as traditional IFA-based (i.e., 2-fold) titers. The modified ELISA correlated significantly with IFA and was subsequently used to compute endpoint antibody titers to Epstein-Barr virus (EBV)-virus capsid antigen (VCA) and cytomegalovirus (CMV) in blood samples taken from 398 pregnant Hispanic women. Four women were EBV negative (1%), while 58 women were CMV negative (14.6%). EBV VCA antibody titers were significantly higher than CMV antibody titers (p<0.001). This method allows titering of herpesvirus antibodies by ELISA suitable for large population-based studies. In addition, the LOOKUP table enables conversion from OD-derived titers into 2-fold titers for comparison of results with other studies. [ABSTRACT FROM AUTHOR]

Finances are a prevalent source of stress. In a sample of 799 nursing home workers measured multiple times over 18 months, we found that higher perceived income inadequacy, the perception that one's expenses exceeds one's incomes, was associated with poorer self-reported mental health indicators and Epstein-Barr Virus antibody titers (a marker of cell-mediated immune function). Perceived income inadequacy predicted outcomes over and above the role of other socioeconomic status variables (objective household income and education). Mental health variables were not related to Epstein-Barr Virus antibody titers. Additionally, we found an interaction between perceived income inadequacy and informal caregiver status on our mental health outcomes; informal caregivers with higher perceived income inadequacy had poorer mental health than non-caregivers with the same perceived income inadequacy. Our findings may add nuance to the reserve capacity model, which states that those at lower socioeconomic levels are at higher risk of adverse health outcomes partly because they have fewer resources to address demands and strain. Perceived income inadequacy may significantly predict mental and physical well-being beyond other socioeconomic status variables, especially among lower-income employees. Caregiving stress and perceived income inadequacy may have synergistic effects on mental health. • Perceived income inadequacy predicted stress and distress beyond household income. • Perceived income inadequacy predicted Epstein-Barr virus antibody titers. • Informal caregivers had poorer mental health at high perceived income inadequacy.

Highlights • At two visits, couples discussed marital disagreements and gave blood samples. • Hostile behaviors and depression predicted greater bacterial LPS translocation. • In turn, greater bacterial translocation was related to higher inflammation. • Bacterial translocation explained hostility and depression's links to CRP. Abstract Background Marital distress and depression work in tandem to escalate risks for inflammation-related disorders. Translocation of bacterial endotoxin (lipopolysaccharide, LPS) from the gut microbiota to blood circulation stimulates systemic inflammatory responses. Methods To investigate increased gut permeability (a "leaky gut") as one potential mechanistic pathway from marital distress and depression to heightened inflammation, this secondary analysis of a double-blind, randomized crossover study examined serial assessments of two endotoxin biomarkers, LPS-binding protein (LBP) and soluble CD14 (sCD14), as well as C-reactive protein (CRP), interleukin 6 (IL-6), and tumor necrosis factor alpha (TNF-α) during two separate 9.5 h visits. The 43 (N = 86) healthy married couples, ages 24–61 (mean = 38.22), discussed a marital disagreement during both visits; behavioral coding of these interactions provided data on hostile marital behaviors, a hallmark of marital distress. The Structured Diagnostic Interview for DSM-IV assessed participants' mood disorder history. Results Participants with more hostile marital interactions had higher LBP than those who were less hostile. Additionally, the combination of more hostile marital interactions with a mood disorder history was associated with higher LBP/sCD14 ratios. Higher LBP and LBP/sCD14 were associated with greater CRP production; for example, only 21% of low LBP participants (lowest quartile) had average CRP across the day > 3, compared to 79% of those in the highest quartile. Higher sCD14 was associated with higher IL-6. Conclusions These bacterial LPS translocation data illustrate how a distressed marriage and a mood disorder history can promote a proinflammatory milieu through increased gut permeability, thus fueling inflammation-related disorders.

HEART beat , *INFLAMMATION , *MORTALITY , *MARITAL conflict , *SYNCHRONIC order - Abstract
Hostile conflict in marriage can increase risks for disease and mortality. Physiological synchrony between partners—e.g., the linkage between their autonomic fluctuations—appears to capture engagement, or an inability to disengage from an exchange, and thus may amplify the health risks of noxious interactions such as marital conflict. Prior work has not examined the unique health correlates of this physiological signature. To test associations between couples’ heart rate variability (HRV) synchrony during conflict and inflammation, 43 married couples engaged in a marital problem discussion while wearing heart monitors and provided four blood samples; they repeated this protocol at a second visit. When couples’ moment-to-moment HRV changes tracked more closely together during conflict, they had higher levels of three inflammatory markers (i.e., IL-6, stimulated TNF-α, and sVCAM-1) across the day. Stronger HRV synchrony during conflict also predicted greater negative affect reactivity. Synchrony varied within couples, and was related to situational factors rather than global relationship traits. These data highlight partners’ HRV linkage during conflict as a novel social-biological pathway to inflammation-related disease. [ABSTRACT FROM AUTHOR]

Background This study aimed to (1) provide a comprehensive characterization of depressive symptoms profiles, and (2) examine the cross-sectional association between depressive symptom profiles and cardio-metabolic outcomes, including metabolic syndrome and obesity, while controlling for sociodemographic variables, health behaviors and inflammation. Methods Our sample was comprised of 1085 participants (55.80% female) enrolled in the MIDUS-II biomarker study. Latent profile analysis (LPA) was used to derive depressive symptom profiles using subscales of the Mood and Anxiety Symptom Questionnaire (MASQ) and the Center for Epidemiologic Studies Depression Scale (CES-D) subscales as well as Pittsburgh Sleep Quality Index (PSQI) global score. Metabolic syndrome was defined according to the Interim Joint Statement definition. CRP was used as a marker of inflammation. Results Four depressive symptom profiles were identified. The “No Symptoms” subgroup (60.65% of the sample) had the lowest overall scores across subscales. The “Mild Symptoms” subgroup (26.73%) was characterized by lower scores across indicators, with subscales measuring somatic symptoms being the highest within group. The “Moderate Symptoms” subgroup (10.32%) had higher scores across subscales (1 SD above the mean), with subscales measuring negative affect/loss of interest being the highest within group. Finally, the “Acute symptoms” subgroup (2.30%) was characterized by the highest overall scores (1.5–3 SD above the mean) on all indicators. After controlling for sociodemographic characteristics and health behaviors, the “Moderate Symptoms” subgroup was significantly associated with metabolic syndrome (OR = 1.595, p = 0.035) and obesity (OR = 1.555, p = 0.046). Further, there was a trend between the “Mild Symptoms” subgroup and the presence of obesity (OR = 1.345, p = 0.050). Inflammation attenuated these associations. Conclusions Four depressive symptom profiles were identified among healthy mid-life individuals in the US. These profiles are differentially associated with cardio-metabolic outcomes. Future work should examine whether distinct symptom profiles may reflect differential pathways to increased risk, and whether tailored management of symptoms is needed. [ABSTRACT FROM AUTHOR]

Spousal bereavement is one of the most stressful experiences in adulthood. In a sample of 183 widow(er)s, bereaved about three months prior, we examined the intersection of employment, family income, and health outcomes (proinflammatory marker production, perceived stress, and grief symptoms). Bereaved employees had higher levels of monocyte-stimulated interleukin-6, tumor necrosis factor-α, chemokine ligands 4, and perceived stress than bereaved retirees. We also found an interaction such that family income was positively associated with perceived stress and grief symptoms for employed window(er)s, but not for retirees. These findings align with the reserve capacity model, which states that people at higher levels of socioeconomic status have more psychosocial resources to address psychosocial stressors. Employment likely served as an added psychological and inflammatory burden for all bereaved workers, except those with the highest incomes. • Widowed workers had higher proinflammatory marker production than widowed retirees. • Widowed workers had higher perceived stress than widowed retirees. • Widowed workers with lower and middle levels of income may be more vulnerable. • Employment may be a feature underlying risk and resilience for some widow(er)s.

Individuals who perform poorly on measures of the executive function of inhibition have higher anxious arousal in comparison to those with better performance. High anxious arousal is associated with a pro-inflammatory response. Chronically high anxious arousal and inflammation increase one’s risk of developing type 2 diabetes. We sought to evaluate anxious arousal and inflammation as underlying mechanisms linking inhibition with diabetes incidence. Participants ( N = 835) completed measures of cognitive abilities, a self-report measure of anxious arousal, and donated blood to assess interleukin-6 (IL-6) and glycated hemoglobin (HbA1c). Individuals with low inhibition were more likely to have diabetes than those with high inhibition due to the serial pathway from high anxious arousal to IL-6. Findings remained when entering other indicators of cognitive abilities as covariates, suggesting that inhibition is a unique cognitive ability associated with diabetes incidence. On the basis of our results, we propose several avenues to explore for improved prevention and treatment efforts for type 2 diabetes. [ABSTRACT FROM AUTHOR]

Background Longitudinal studies have implicated both marital distress and depression in the development of the metabolic syndrome, a risk factor for diabetes and cardiovascular disease. This study addressed the impact of hostile marital interactions and a mood disorder history on obesity-related metabolic responses to high-fat meals. Methods This double-blind, randomized crossover study included serial assessments of resting energy expenditure (REE), fat and carbohydrate oxidation, triglycerides, insulin, glucose, interleukin 6 (IL-6), and tumor necrosis factor alpha (TNF-α) before and after two high-fat meals. During two separate 9.5 h visits, 43 healthy married couples, ages 24–61 (mean = 38.22), received either a high saturated fat meal or a high oleic sunflower oil meal, both 930 kcal and 60 g fat. The Structured Diagnostic Interview for DSM-IV assessed mood disorder history. Couples discussed a marital disagreement during both visits; behavioral coding of these interactions provided data on hostile marital behaviors. Results Men and women who displayed more hostile behaviors and who also had a mood disorder history had significantly lower post-meal REE, higher insulin, and higher peak triglyceride responses than other participants, with nonsignificant effects for fat and carbohydrate oxidation. Participants with a mood disorder history had a steeper rise in postprandial IL-6 and glucose than those without a past history. Higher levels of hostile behaviors were associated with higher post-meal TNF-α. The two meals did not differ on any outcome assessed. Conclusions People spend about 18 of every 24 h in a postprandial state, and dining with one's partner is a common daily event. Among subjects with a mood disorder history, the cumulative 6.75-h difference between high and low hostile behaviors translates into 128 kcal, a difference that could add 7.6 pounds/year. Our findings illustrate novel pathways through which chronic marital stress and a mood disorder history synergistically heighten the risk for obesity, metabolic syndrome, and cardiovascular disease.

• Spousal caregivers and widow(er)s have worse cognitive outcomes than controls. • Spousal caregivers and widow(er)s have increased long-term risk for dementia. • Stress-related pathways may contribute to abnormal cognitive decline. • We propose a biopsychosocial model linking partner loss to increased ADRD risk. • Longitudinal research on stress, health, and cognition in this population is needed. Accumulating research suggests that stressful life events, especially those that threaten close intimate bonds, are associated with an increased risk of dementia. Grieving the loss of a spouse, whether in the form of caregiving or after the death, ranks among 'life's most significant stressors', evoking intense psychological and physiological distress. Despite numerous studies reporting elevated dementia risk or poorer cognition among spousal caregivers and widow(er)s compared to controls, no review has summarized findings across cognitive outcomes (i.e., dementia incidence, cognitive impairment rates, cognitive performance) or proposed a theoretical model for understanding the links between partner loss and abnormal cognitive decline. The current systematic review summarizes findings across 64 empirical studies. Overall, both cross-sectional and longitudinal studies revealed an adverse association between partner loss and cognitive outcomes. In turn, we propose a biopsychosocial model of cognitive decline that explains how caregiving and bereavement may position some to develop cognitive impairment or Alzheimer's disease and related dementias. More longitudinal studies that focus on the biopsychosocial context of caregivers and widow(er)s are needed. [ABSTRACT FROM AUTHOR]

Spousal bereavement can lead to adverse health outcomes; however, not all widow(er)s experience the same degree of health problems. Thus, it is important to understand the contribution of disparities (e.g., childhood maltreatment and subjective social status) that may underlie adverse health outcomes that arise following bereavement. We collected data from 130 spousally bereaved individuals at 3-time points (3 months post-loss, 4 months post-loss, and 6 months post-loss). Using mixed models, we assessed the interaction of childhood maltreatment, subjective social status, and time to predict changes in proinflammatory cytokine production, depressive symptoms, grief symptoms. We found a significant interaction between childhood maltreatment, subjective social status, and time predicting proinflammatory cytokine production (beta > −0.01, p = 0.048), depressive symptoms (beta = 0.008, p =.010), and grief symptoms (beta = 0.001 p =.001). This study highlights the role of disparities related to childhood maltreatment and subjective social status on adverse health outcomes following spousal bereavement. • Disparities related to child maltreatment and subjective social status impact health. • Notably, they can impact proinflammatory cytokine production following bereavement. • These disparities also impact depressive and grief symptoms following bereavement.

Major depressive disorder (MDD) is an important contributor to the total disease burden because of its high comorbidity with chronic illnesses. Many people with high levels of depressive symptoms exhibit elevated systemic inflammation, but inflammation is not a necessary determinant of depression onset. Among those who recently experienced the death of a spouse, we investigated whether (a) inflammation assessed early in bereavement predicted future depressive symptoms and whether (b) inflammation predicted change in depressive symptoms from baseline to follow-up. Ninety-nine spousally bereaved individuals (M = 68.61, SD = 10.70) from a larger study were evaluated at baseline (3 months post-death) and follow-up (6 months post-death). Subjects received a venous blood draw and completed the Center for Epidemiologic Studies Depression Scale (CES-D). Stimulated T-cell derived cytokines (IL-6, TNF-α, and IFN-γ) were assessed individually and as a pro-inflammatory composite index. After controlling for confounding factors (i.e., age, sex, body mass index, race, ethnicity, anti-inflammatory medication, days since spousal death, smoking status, comorbidities), individuals with higher levels of IL-6, TNF-α, and IFN-γ at baseline exhibited more depressive symptoms (composite index, p =.05) and an increased probability of experiencing clinical levels of depression (CES-D score ≥ 16) (composite index, p =.04). Inflammatory levels were not predictive of change in depressive symptoms or in clinical depression status from baseline to follow-up. Among individuals who did not experience clinical levels of depression at baseline, baseline inflammatory levels predicted clinical levels of depression 3 months later (p =.03). This study provides support for an inflammatory mechanism underlying depression following bereavement. It suggests that one's inflammatory profile following a significant social stressor in older adulthood can be prognostic of depression risk months later. These findings add to our understanding of the physiological and mental health risks experienced by the bereaved population and provide insight into identifying vulnerable widow(er)s at risk for maladaptive grief coping. • Higher inflammation at 3 months post-loss predicted future depressive symptoms. • Higher inflammation increased odds of future clinical depression risk. • Inflammation did not predict change in depressive symptoms. • Among non-depressed widow(er)s, inflammation predicted future depression status. • Results support an inflammatory mechanism underlying bereavement-related depression.

HYDROCORTISONE , *PERCEIVED Stress Scale , *MARRIED people - Abstract
• Married couples provided 5 salivary cortisol samples during a 9.5 h visit. • Coding of couples' conflicts provided data on positive and negative behavior. • A stressed spouse was associated with slower declines in one's own cortisol. • Negative and less positive behaviors and a stressed spouse related to higher cortisol. • We show how partners "get under the skin" to influence stress-related health risk. Perceived stress can lead to dysregulated cortisol patterns, including blunted peaks and flatter slopes, which are associated with increased morbidity and mortality risks. Couples' interdependence provides a prime opportunity for partners' stress to disrupt a healthy cortisol pattern. This study examined how individuals' own perceived stress and their partners' perceived stress shape cortisol levels and slopes across the day, as well as how positive and negative behaviors during conflict discussions impact associations between stress and cortisol. Both partners of a married couple (n = 43 couples, 86 individuals) completed a full day in-person visit. Each partner completed the Perceived Stress Scale, and all couples engaged in a 20-min marital problem discussion which was recorded and later coded for positive and negative behaviors using the Rapid Marital Interaction Coding System (RMICS). Partners also provided five salivary cortisol samples across the day, two samples before the conflict and three after the conflict. The dyadic design and analyses provided a way to account for the interdependent nature of married couples' data, as well as to use the Actor-Partner Interdependence Model (APIM) to assess the mutual influence of spouses' stress on cortisol. Individuals with more stressed partners had flatter cortisol slopes than individuals with less stressed partners, who showed steeper and thus healthier declines across the day. Individuals' cortisol levels at the beginning of the day were similar regardless of their partners' perceived stress, but individuals with more stressed partners had higher cortisol levels 30-min, 1 h, and 4 h after the conflict discussion than those with less stressed partners. Couples' behavior during the conflict moderated the relationship between partner perceived stress and average cortisol; when couples used more negative and less positive behaviors, individuals with more stressed partners had higher average cortisol levels than those with less stressed partners. On a day couples experienced conflict, having a partner with higher perceived stress is associated with dysregulated cortisol patterns, including higher levels and flatter slopes, but having a partner with lower perceived stress is linked to steeper and thus healthier cortisol declines. A partner's stress was particularly consequential for one's own cortisol when couples used more negative and fewer positive behaviors during a conflict discussion. This research adds to the growing literature on pathways connecting marital interactions to important biorhythms and health. [ABSTRACT FROM AUTHOR]

• Spouses share common risks for cardiometabolic diseases, according to prior work. • Nevertheless, mechanisms of disease concordance remain poorly understood. • In our study closer, happier, older couples had greater cardiometabolic similarity. • Associations were independent from the effects of health behavior concordance. Spouses share common risks for cardiometabolic diseases: a person's diabetes or hypertension raises the partner's odds of developing the same condition. The mechanisms responsible for this disease concordance remain poorly understood. To examine three factors that may modulate partners' cardiometabolic similarity—closeness, hostile marital behavior, and age—and to explore whether health behavior concordance plays a role, on two separate occasions 43 healthy couples ages 24–61 provided fasting glucose, metabolic data (fat and carbohydrate oxidation), and resting blood pressure before discussing one of their most severe marital disagreements. Accounting for the fixed effects of sex, age, study visit, and abdominal fat on cardiometabolic levels, we found that aspects of health behavior concordance were associated with greater similarity in glucose, diastolic blood pressure (DBP), and carbohydrate and fat metabolism. Independent of health behavior concordance, partners who felt closer and behaved in a less hostile way had more similar rates of fat oxidation; less hostile partners also shared greater overlap in carbohydrate oxidation. Likewise, fasting glucose and DBP were more similar within older couples compared to younger pairs, beyond the effects of health behavior concordance. In sum, our data captured preclinical similarities in cardiometabolic health among disease-free couples, which may form the basis for their long-term overlapping disease risks. Closer, less hostile, and older couples shared more similar fasting glucose, metabolic data, and blood pressure; importantly, health behavior concordance did not explain all associations. These novel data suggest that multiple paths may lead to couples' shared disease risks. [ABSTRACT FROM AUTHOR]

• Cognitive reappraisal impacts the heart rate variability—telomere length connection. • Individuals with high cognitive reappraisal frequency had a significant association. • Individuals with low cognitive reappraisal frequency did not show this relationship. • Cognitive reappraisal buffers the link between chromosomal integrity and vagal tone. Individuals who poorly regulate emotion exhibit premature aging and worse general health. Telomere shortening, a prognostic biomarker of physical health, is related to aging, poor immunocompetence and autonomic nervous system functioning. Cognitive reappraisal is one type of emotion regulation strategy, which involves changing one's appraisal of an aversive situation to modify its emotional impact. Heart rate variability (HRV; i.e., oscillations in heart rate) relates to emotion regulatory processes, such that higher HRV typically reflects greater regulatory capacity. Previous research has identified a positive association between HRV and telomere length. Importantly, the association between HRV and telomere length may change depending on how often an individual uses cognitive reappraisal. One hundred and thirty-seven healthy participants completed measures of cognitive reappraisal frequency, HRV, and underwent blood draws to measure telomere length (computed with the relative ratio of telomere repeat copy number to single copy gene number) in the T cell effector population, CD8+CD28–. Cognitive reappraisal moderated the relationship between telomere length and HRV such that individuals with high cognitive reappraisal frequency had a significant positive association between HRV and telomere length, while individuals with average and less than average frequency did not exhibit this relationship. The results suggest that frequent usage of cognitive reappraisal enhances the already positive influence of HRV on chromosomal integrity in CD8+CD28– T lymphocytes. Although future research is needed to test these effects causally, these findings suggest that regularly using emotion regulation techniques may buffer the relationship between autonomic nervous system functioning and chromosomal integrity in immune cells.
