Evaluation of Focal Adhesion Mediated Subcellular Curvature Sensing in Response to Engineered Extracellular Matrix

Fibril curvature is bioinstructive to attached cells. Similar to natural healthy tissues, an engineered extracellular matrix can be designed to stimulate cells to adopt desired phenotypes. To take full advantage of the curvature control in biomaterial fabrication methodologies, an understanding of the response to fibril subcellular curvature is required. In this work, we examined morphology, signaling, and function of human cells attached to electrospun nanofibers. We controlled curvature across an order of magnitude using nondegradable poly(methyl methacrylate) (PMMA) attached to a stiff substrate with flat PMMA as a control. Focal adhesion length and the distance of maximum intensity from the geographic center of the vinculin positive focal adhesion both peaked at a fiber curvature of 2.5 μm-1 (both ∼2× the flat surface control). Vinculin experienced slightly less tension when attached to nanofiber substrates. Vinculin expression was also more affected by a subcellular curvature than structural proteins α-tubulin or α-actinin. Among the phosphorylation sites we examined (FAK397, 576/577, 925, and Src416), FAK925 exhibited the most dependance on the nanofiber curvature. A RhoA/ROCK dependance of migration velocity across curvatures combined with an observation of cell membrane wrapping around nanofibers suggested a hybrid of migration modes for cells attached to fibers as has been observed in 3D matrices. Careful selection of nanofiber curvature for regenerative engineering scaffolds and substrates used to study cell biology is required to maximize the potential of these techniques for scientific exploration and ultimately improvement of human health

Increased risk of depression in non-depressed HIV infected men with sleep disturbance: Prospective findings from the Multicenter AIDS Cohort Study.

ObjectiveSleep disturbance is a known risk factor for depression, but it is not known whether sleep disturbance contributes to greater risk of depression in those infected with human immunodeficiency virus (HIV+) as compared to those uninfected with HIV (HIV-).MethodsUsing data from the Multicenter AIDS Cohort Study, a population-based prospective study of men who have sex with men (MSM), self-reported sleep disturbance (>2 weeks) and depressive symptoms (Clinical Epidemiologic Scale for Depression, CES-D) were assessed every 6 months over 12 years of follow-up. Adjusted mixed effects logistic regression analyses tested whether sleep disturbance predicted depression (CES-D ≥ 16) at the immediate subsequent visit, and so on over 12 years, in non-depressed HIV+(N = 1054; 9556 person-visits) and non-depressed HIV- (N = 1217; 12,680 person-visits). In HIV+ vs. HIV- MSM, linearly estimated average incidence of depression and normalized cumulative rate of depression over 12 years were compared.ResultsIn the HIV+ MSM, sleep disturbance was associated with a significant increase in depression 6 months later (OR = 1.6; 95% CI, 1.30, 1.96), which was significantly greater (P < .05) than in HIV- MSM (OR = 1.16; 95% CI, 0.94, 1.44). HIV status and sleep disturbance interacted (P < .001), such that incidence of depression and normalized cumulative rate of depression were greater in HIV+ with sleep disturbance than in HIV+ without sleep disturbance and HIV- groups (all P's < 0.001).ConclusionsHIV+ persons who report sleep disturbance represent a high risk group to be monitored for depression, and possibly targeted for insomnia treatment to prevent depression.

Is a Sense of Inequity an Ancestral Primate Trait? Testing Social Inequity in Cotton Top Tamarins

To address a controversy in the literature concerning whether monkeys show an aversion to inequity, individuals of a New World monkey species, cotton top tamarins (Saguinus oedipus) were tested in an offering task and in a bartering task. At issue was whether the monkeys rejected rewards because of a violation of expectancy of the preferred reward, or whether they rejected rewards because of a sensitivity to socially mediated inequity. The data from both tasks indicated that the subjects were more likely to reject when preferred rewards were presented, either because of another animal eating the reward (the social condition) or because of rewards being presented but inaccessible. The bartering task led to the only behavioral indication of aversion due specifically to social inequity, which was demonstrated when tamarins’ sensitivity to the difference in rewards increased with exposure to other tamarins working to receive the preferred rewards. The results suggest that social inequity aversion will be assessed by tamarins, and possibly by other primates, only under conditions of limited resources and a requirement of work, which may make the situation a bit more competitive and thus drives attention toward both social and reward evaluatio

Differing growth responses to nutritional supplements in neighboring health districts of Burkina Faso are likely due to benefits of small-quantity lipid-based nutrient supplements (LNS)

Background : Of two community-based trials among young children in neighboring health districts of Burkina Faso, one found that small-quantity lipid-based nutrient supplements (LNS) increased child growth compared with a non-intervention control group, but zinc supplementation did not in the second study. Objectives : We explored whether the disparate growth outcomes were associated with differences in intervention components, household demographic variables, and/or children's morbidity. Methods : Children in the LNS study received 20g LNS daily containing different amounts of zinc (LNS). Children in the zinc supplementation study received different zinc supplementation regimens (Z-Suppl). Children in both studies were visited weekly for morbidity surveillance. Free malaria and diarrhea treatment was provided by the field worker in the LNS study, and by a village-based community-health worker in the zinc study. Anthropometric assessments were repeated every 13-16 weeks. For the present analyses, study intervals of the two studies were matched by child age and month of enrollment. The changes in length-for-age z-score (LAZ) per interval were compared between LNS and Z-Suppl groups using mixed model ANOVA or ANCOVA. Covariates were added to the model in blocks, and adjusted differences between group means were estimated. Results : Mean ages at enrollment of LNS (n = 1716) and Z-Suppl (n = 1720) were 9.4 +/- 0.4 and 10.1 +/- 2.7 months, respectively. The age-adjusted change in mean LAZ per interval declined less with LNS (-0.07 +/- 0.44) versus Z-Suppl (-0.21 +/- 0.43; p<0.0001). There was a significant group by interval interaction with the greatest difference found in 9-12 month old children (p<0.0001). Adjusting for demographic characteristics and morbidity did not reduce the observed differences by type of intervention, even though the morbidity burden was greater in the LNS group. Conclusions : Greater average physical growth in children who received LNS could not be explained by known cross-trial differences in baseline characteristics or morbidity burden, implying that the observed difference in growth response was partly due to LNS

SLEEP, PRAY, AND STATUS: RELIGIOSITY AS A MODERATOR IN THE ASSOCIATION BETWEEN SUBJECTIVE SOCIAL STATUS AND SLEEP IN AFRICAN AMERICAN YOUNG ADULTS

Abstract 2101 SLEEP, PRAY, AND STATUS: RELIGIOSITY AS A MODERATOR IN THE ASSOCIATION BETWEEN SUBJECTIVE SOCIAL STATUS AND SLEEP IN AFRICAN AMERICAN YOUNG ADULTS Elissa Kim, HS, Elizabeth A. Brown, HS, Alison Kwan, HS, Amara Craig, HS, Nataria T. Joseph, PhD, Psychology, Pepperdine University, Malibu, CA, Laurel M. Peterson, PhD, Psychology, Bryn Mawr, Bryn Mawr, PA Background: With growing importance being placed on biopsychosocial health, researchers have raised awareness about the role that subjective social status (SSS) plays in sleep. This is particularly important when examining African Americans given that they are at higher risk for experiencing poor sleep quality. However, religiosity has shown to impart lasting health benefits and behaviors that may be protective for sleep health. For example, the theory of religious coping proposes that religious behaviors can lead to adaptive stress responses that protect biopsychosocial health from the stressors of perceived low social status. Interactions between SSS and religiosity in predicting sleep quality are understudied. Objective: We aimed to examine whether SSS is associated with sleep quality and whether religiosity measured at global and momentary levels moderates this association in African American young adults. Methods: A sample of 129 healthy African American young adults completed 2 or 4 days of hourly ecological momentary assessment (EMA) surveys and a baseline survey. SSS was measured using the MacArthur Scale of Subjective Social Status, sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI), and religious behaviors were measured using recommended items from the Fetzer Institute (2003). A subsample of participants also wore an ActiGraph watch to assess objective sleep quality. Results: Lower SSS with respect to ones’ community (but not with respect to the United States population) was associated with worse sleep quality, b = -.28, p = .032, η2 = .04. Further, there was a significant interaction between SSS (with respect to the US population) and religiosity, p = .049, η2 = .06. Specifically, among those exhibiting higher SSS with respect to the US population, religious behaviors were protective, i.e., associated with better sleep quality. Results regarding momentary level religious behaviors and objective sleep will be presented. Conclusions: Results extend previous literature and suggest refinements to the theory of religious coping given that religiosity was shown to have a stronger positive effect on sleep quality among African Americans who reported having a higher perceived social status. Future research should continue to explore these factors at the momentary level to illuminate mechanisms by which these interactions unfold.

Concomitant Cannabis Misuse and Associations with Depression, Pain and Substance Misuse among Patients Prescribed Opioids

Background: Cannabis use is common among individuals with pain who are prescribed opioids, occurring in approximately 10% of this population. This study aims to explore the relationship between non-medical cannabis use and other health risks among individuals filling opioids at community pharmacies. Methods: This study was an exploratory secondary data analysis of a National Drug Abuse Treatment Clinical Trials Network (CTN)-sponsored study, Validation of a Community Pharmacy-Based Prescription Drug Monitoring Program Risk Screening, examining the relationship between risky cannabis use and depressive symptoms, pain, overdose, and other substance misuse among individuals filling opioid prescriptions in community pharmacies (N = 1440). Results: Participants reporting moderate- to high-risk compared to low-risk cannabis use were more likely to report depressive symptoms (adjusted OR = 1.67, 95% CI = 1.11–2.56), history of overdose (adjusted OR = 2.15, 95% CI = 1.34–3.44), and moderate- to high-risk use of alcohol (adjusted OR = 2.10, 95% CI = 1.28–3.45), opioids (adjusted OR = 2.50, 95% CI = 1.67–3.76), sedatives (adjusted OR = 2.58, 95% CI = 1.72–3.86), stimulants (adjusted OR = 4.79, 95% CI = 2.83–8.01), and tobacco (adjusted OR = 3.60, 95% CI = 2.47–5.24). Conclusions: Community pharmacies may be valuable sites for identifying, studying, and intervening with substance use problems
