- Abstract
Objective: Despite the well-established association between self-rated health (SRH) and health, little is known about the potential psychobiological mechanisms responsible for such links and if these associations differ by age. The main goals of this study were to investigate the links between SRH and ambulatory blood pressure (ABP), if age moderated the risk, and the health behavior/affective mechanisms responsible for such links., Methods: A total of 188 men and women (94 married couples; ages, 18-63 years) completed a standard measure of SRH and a 1-day ABP assessment. Multilevel models were run to examine whether SRH was associated with daily ABP and whether these links were moderated by age. The Monte Carlo method was used to construct confidence intervals for mediation analyses., Results: Results indicated that poor SRH was associated with higher ambulatory systolic blood pressure (SBP; b = 3.14, SE = 0.68, p < .001) and diastolic blood pressure (DBP; b = 1.34, SE = 0.43, p = .002) levels. Age also moderated the links between SRH and ambulatory SBP (b = 0.19, SE = 0.08, p = .011) and DBP (b = 0.14, SE = 0.05, p = .004), with links being stronger in relatively older individuals. However, only daily life negative affect significantly mediated the age by SRH interaction for both ambulatory SBP and DBP., Conclusions: These results highlight the potential psychobiological mechanisms linking SRH to longer-term health outcomes. Such work can inform basic theory in the area as well as intervention approaches that target such pathways.

- Abstract
Background: Subjective sleep quality is a predictor of important health outcomes, but little work has examined the social context of sleep that might inform theoretical models and intervention approaches. The present study tested actor-partner models of sleep quality and its links to inflammatory markers., Method: Participants were 84 middle-age to older adult heterosexual married couples who completed the Pittsburgh Sleep Quality Index and had blood drawn for determination of CRP and IL-6 levels., Results: Main results indicated that only actor levels of poor global sleep quality predicted higher CRP levels. No actor × partner or gender × actor/partner interactions were significant. These results were also not moderated by relationship quality. Secondary analyses, focused on the different components of sleep quality, revealed marginally significant evidence for partner's poor sleep (i.e., sleep disturbances, sleep latency) on one's own inflammatory outcomes., Conclusion: These results suggest the promise of modeling sleep quality as a dyadic process that can impact inflammation and potentially related health outcomes.

- Abstract
Objective: Despite its simplicity, single-item measures of self-rated health have been associated with mortality independent of objective health conditions. However, little is known about the mechanisms potentially responsible for such associations. This study tested the association between self-rated heath and inflammatory markers as biological pathways, and whether sleep quality and/or depression statistically mediated such links., Method: Eighty-six heterosexual married couples completed a standard measure of self-rated health, the Center of Epidemiological Studies-Depression Scale, and the Pittsburgh Sleep Quality Index. Participants also had blood drawn for determination of plasma levels of interleukin 6 and high-sensitivity C-reactive protein. The Monte Carlo method was used to construct confidence intervals for mediation analyses., Results: Results indicated that poor self-rated health was associated with higher CRP levels (B = .31, SE = .14, p = .028). Importantly, the Monte Carlo mediational analyses showed that these results were statistically mediated by sleep quality (aXb = 0.10, 95% confidence interval = 0.003 to 0.217) but not depressive symptoms (aXb = 0.03, 95% confidence interval = -0.03 to 0.10)., Conclusions: These results highlight the biological and behavioral mechanisms potentially linking self-rated health to longer-term health outcomes. Such work can inform basic theory in the area as well as intervention approaches that target such pathways.

- Abstract
Background: The quality of interpersonal ties-especially closer relationships-appears to be associated with physical health outcomes. Sleep is one pathway through which relationships and health appear to be linked, but this has been inadequately investigated in the context of dyadic attachment., Purpose: The present study examined links between relationship-specific attachment anxiety (which can involve preoccupation with one's partner, negative relationship cognitions, and fear of abandonment) and avoidance (e.g., low emotional investment or intimacy) and sleep quality., Methods: Attachment, assessed using the Experience in Close Relationship (ECR), was used to predict Pittsburgh Sleep Quality Inventory (PSQI)-assessed sleep quality in 92 married heterosexual couples via actor-partner interdependence models. Depression was examined as a potential mediator of this association., Results: Consistent with hypotheses, actors' anxious attachment predicted diminished quality of their own sleep, whereas actors' avoidant attachment was unrelated to their own sleep quality. Results further suggested that couples in which both spouses were higher in attachment anxiety experience better sleep quality (b = -0.74, SE = 0.28, p = .0082, 95% CI [-1.287, -0.196]). Conversely, couples in which both spouses were higher in attachment avoidance showed poorer sleep quality (b = 0.56, SE = 0.23, p = .0188, 95% CI [0.095, 1.016]). These effects were found to be independent of marital satisfaction and depression. Some evidence was also consistent with mediation of links between attachment and sleep quality via depression., Conclusions: Results suggest adult romantic attachment and sleep are associated in complex ways, highlighting the importance of dyadic approaches to the study of relationships, sleep, and health.

- Abstract
Objective: While the implications of social support are increasingly well understood, no meta-analytic review to date has examined the intersection of the social support and sleep literatures. The aims of this meta-analysis were primarily to review the association between social support and sleep and additionally to test several proposed moderators from prior work., Method: Using a literature search and the ancestry approach, the review identified 61 studies with a total of 105,437 participants., Results: Random-effects modeling showed that greater social support was significantly related to improved sleep outcomes (Zr = -.152). These results were not moderated by the operationalization of support, study design, or chronic conditions., Conclusions: These data indicate a robust association between social support and favorable sleep outcomes.

- Abstract
Objective: Social support and social integration have been linked to lower rates of morbidity and mortality. However, the biological mechanisms responsible for such links need greater attention to advance theory and unique intervention opportunities. The main aim of this article was to conduct a meta-analytic review of the association between social support-social integration and inflammatory cytokines (e.g., interleukin-6, C-reactive protein) and test several proposed moderators from prior qualitative reviews., Method: A literature search was conducted using the ancestry approach and with databases PsycINFO, Medline, and EMBASE by crossing the exact keywords social support or social integration with inflammation . The review identified 41 studies with a total of 73,037 participants., Results: The omnibus meta-analysis showed that social support-social integration were significantly related to lower levels of inflammation (Zr = -.073). These results were not moderated by the operationalization of social relationships or the type of population, cytokine, and design., Conclusions: These data suggest that inflammation is at least one important biological mechanism linking social support and social integration to the development and course of disease. Future work should continue to build on this review and address next-generation questions regarding antecedent processes, mechanisms, and other potential moderators.

- Abstract
Life satisfaction has been linked to lower cardiovascular disease mortality. However, much less is known about the biological mechanisms linking life satisfaction to physical health. In addition, the dyadic context of life satisfaction has not been considered despite increasing evidence that partners influence each other in health-relevant ways. These questions were addressed with 94 married couples who completed measures of life satisfaction and had their blood drawn for determination of interleukin-6 (IL-6) and C-reactive protein (CRP). Actor-partner models showed that higher actor levels of life satisfaction predicted lower levels of IL-6 and CRP (p's < .05), whereas partner levels of life satisfaction did not predict any measure of inflammation. The actor results were not mediated by marital satisfaction or health behaviors. Finally, no actor × partner interactions were significant and these links were not moderated by marital satisfaction. These data highlight inflammation as a potentially important biological mechanism linking actor reports of life satisfaction to lower cardiovascular mortality.

- Abstract
Dispositional optimism has been related to beneficial influences on physical health outcomes. However, its links to global sleep quality and the psychological mediators responsible for such associations are less studied. This study thus examined if trait optimism predicted global sleep quality, and if measures of subjective well-being were statistical mediators of such links. A community sample of 175 participants (93 men, 82 women) completed measures of trait optimism, depression, and life satisfaction. Global sleep quality was assessed using the Pittsburgh Sleep Quality Index. Results indicated that trait optimism was a strong predictor of better PSQI global sleep quality. Moreover, this association was mediated by depression and life satisfaction in both single and multiple mediator models. These results highlight the importance of optimism for the restorative process of sleep, as well as the utility of multiple mediator models in testing distinct psychological pathways.

- Abstract
Although existing life span models suggest that positivity in relationships should benefit the health of older adults, much less is known about how relationships that contain both positive and negative aspects (i.e., ambivalent ties) might influence age-associated cardiovascular risk. Given the increased interpersonal stress associated with ambivalent ties, the SAVI model would predict that older adults might be more negatively influenced given age-related changes in physiological flexibility. In this study, the quality of an individual's social network (i.e., supportive, ambivalent, aversive) was used to predict cardiovascular reactivity during laboratory stress across a 10-month follow-up period in 108 participants between the ages 30 to 70. Results revealed evidence that the number of ambivalent network ties predicted greater increases in diastolic blood pressure reactivity. Importantly, there was an Age × Ambivalent Ties interaction in which the number of ambivalent ties was related to greater increases in systolic blood pressure reactivity primarily in older adults. These data are discussed in terms of the health implications of social networks across the life span. (PsycINFO Database Record, ((c) 2016 APA, all rights reserved).)

- Abstract
With the availability of more stable radiopharmaceuticals, the ictal single photon emission computed tomography (SPECT) perfusion study has emerged as a useful noninvasive functional neuroimaging tool in the presurgical evaluation of patients with medically intractable partial epilepsy. The purpose of this study was to determine whether the development of a program using trained electroencephalography (EEG) technologists to perform ictal injections in the epilepsy monitoring unit enabled a more efficient delivery of radiopharmaceuticals and therefore a higher specificity and sensitivity of outcome. All patients admitted to the epilepsy monitoring unit for prolonged video/EEG monitoring as part of the presurgical evaluation were eligible for completion of an ictal SPECT study using a three-way needle-free apparatus. Over a 19-month period, 85 (77%)) of 110 eligible patients were successfully injected during typical partial seizures. Various factors were analyzed including latency of ictal injection (27.3+/-20.8 [S.D.] s), radiopharmaceutical wastage (40% dose utilization), radiation safety parameters (1.6% contamination rate), and preliminary data of localizing value. Our results show that ictal SPECT can be a safe, noninvasive procedure completed on a routine basis in the epilepsy monitoring unit when appropriately trained support staff are utilized as part of a structured multidisciplinary program.

- Abstract
This study examined psychopathology, family functioning, and cognitive style in 121 African-American adolescents who attempted suicide. Group means suggested that these youths, when taken together, were not reporting significant psychological distress. However, after classifying the youths into three groups by level of depressive symptoms interesting findings emerged. Youth self-reports of depressive symptoms on the Children's Depression Inventory were associated with the presence of internalizing and externalizing disorders on the Youth Self-Report and Child Behavior Checklist, and with a maladaptive attributional style. Sixty-seven percent of participants classified their family types as maladaptive in terms of levels of cohesion and/or adaptability. In fact, the majority of adolescents and parents reported their families as disengaged. These findings are discussed from a culturally and developmentally sensitive framework which considers key demographic variables (race, socioeconomic status, age). Clinical implications are offered for individual and family interventions.

- Abstract
Before an enteropathogen binds to the small bowel, it must interact with the small-bowel mucus (SBM) layer. To determine whether this interaction involves specific binding of diarrheagenic Escherichia coli, we used a quantitative assay with labeled, purified rabbit SBM. Binding of SBM from an adult rabbit was significantly greater to strain 162, an agglutinating E. coli strain, than it was to RDEC-1, a rabbit pathogen, and was significantly greater to strain 2348/PMAR, an enteropathogenic E. coli strain, than it was to strains 1392+ and 1392-, which are enterotoxigenic E. coli strains with and without colonizing fimbriae, respectively. Binding of strains RDEC-1, 2348/PMAR, and 162-4 was significantly greater to SBM than to bovine serum albumin. Binding of all strains increased in a linear fashion with increasing amounts of SBM and was reproducible (r = 0.85). Binding was significantly greater at pH 5.7 than at pH 7.4 or 8.0 for all five strains. Temperature did not alter the binding of any strain. Strains 162-4 and RDEC-1 bound significantly more to proximal SBM than to rabbit distal SBM, while strains 1392+ and 1392- bound significantly more to distal SBM. Oxidation of sugars from SBM significantly decreased the binding of all strains. Each pathogenic E. coli strain bound distinctively to SBM; the SBM sugars appeared to mediate this binding for all E. coli strains. Binding was also dependent on mucin characteristics, as binding varied by region of the gut (increased for proximal SBM for strains 162-4 and RDEC-1 and for distal SBM for strains 1392+ and 1392-). The developmental age of the gut significantly affected binding only of the rabbit pathogen RDEC-1.
