OBJECTIVES/SPECIFIC AIMS: Wake Forest Baptist Health (WFBH) is an Academic Learning Healthcare System (aLHS) serving 24 counties in North Carolina and Virginia. Like many aLHSs, WFBH experiences strained community relationships attributable to a history of medical and research abuses against marginalized populations. This legacy accompanies longstanding community mistrust in the healthcare system and research. To overcome these challenges, community-engaged research (CEnR) approaches have potential to repair community-academic relationships, improve public health, and empower groups that traditionally have been neglected by or overlooked in research. To develop and revise our understanding of how CEnR is harnessed at WFBH, semi-structured interviews were conducted with investigators and study staff experienced in CEnR approaches. In-depth interview guides were designed iteratively to capture socio-contextual and detailed descriptions of perceptions, experiences, and strategies specific to the use of CEnR. METHODS/STUDY POPULATION: A keyword search performed within WFBH study records identified 51 investigators whom had submitted research proposals related to CEnR within the past ten years. Sixteen were confirmed eligible based on a review of proposal abstracts, of which 14 responded to email invitations agreeing to participate. Four additional participants were referred by initial participants. Eighteen investigators (16 faculty and 2 research associates) provided consent and completed Interviews. RESULTS/ANTICIPATED RESULTS: The participant sample was 50% female with a mean age of 55 years, 11% Black and 89% White, with representation across various academic backgrounds (e.g., anthropology, medicine, psychology, and public health) A majority of participants (89%) hold doctoral degrees (i.e., PhD, DrPH, EdD, MD, and MD-PhD). On average, participants had been employed at WFBH for 13.9 years, and represented various departments including dermatology, epidemiology and prevention, family medicine, neurology, social sciences and health policy, and psychiatry. Nearly all participants (89%) indicated they had never received formal education or training in CEnR, though 100% reported “on-the-job” training in CEnR. Interviews were audio-recorded, transcribed, coded, and analyzed following an inductive thematic approach, from which twenty-two themes emerged across six domains related to CEnR (Table 2), including: Conceptualization and Purpose, Value and Investment, Community-Academic Partnerships, Sustainability, Facilitators, and Challenges. Results also provided key characteristics that define CEnR (Table 3), and yielded 11 emerging needs necessary to enhance CEnR within aLHSs (Table 4). DISCUSSION/SIGNIFICANCE OF IMPACT: The results of this study provide information critical to understanding how CEnR frameworks and approaches can be harnessed not just in Schools of Public Health, but within aLHSs to build and repair community-academic partnerships, inform research and institutional priorities, and address community health concerns. Despite the small sample size, the number of participant interviews was sufficient to achieve saturation while also providing broad and unique perspectives across various fields and CEnR approaches. Overall, participants conceptualized the purpose and goals of CEnR quite similarly, though there was a great deal of variance in how CEnR was defined and operationalized across interviews, indicating a need to more clearly articulate important features that enhance understanding of what CEnR is and what it is not (Table 3). These discrepancies and inconsistencies indicate a potential need for additional formal training in the understanding and use of CEnR approaches, which is supported by the fact that nearly all participants reported receiving no formal training in CEnR. Across all interviews, participants expressed a need for health care providers and researchers to better understand community contexts, social determinants of health, and historical factors influencing community health and participation in research (Table 4). This work and the data presented here are important for informing CEnR approaches and will be useful for guiding the development of a model incorporating the core tenets of CEnR within the mission, vision, and priorities of aLHSs.

We summarize the advantages and disadvantages of some of the most commonly used bioinks. We have probed the mechanical and cytotoxicity properties of Cellink and designed our own bioink from gelatin and Xanthan gum.

Hill (Twin Research and Human Genetics, Vol. 21, 2018, 84–88) presented a critique of our recently published paper in Cell Reports entitled ‘Large-Scale Cognitive GWAS Meta-Analysis Reveals Tissue-Specific Neural Expression and Potential Nootropic Drug Targets’ (Lam et al., Cell Reports, Vol. 21, 2017, 2597–2613). Specifically, Hill offered several interrelated comments suggesting potential problems with our use of a new analytic method called Multi-Trait Analysis of GWAS (MTAG) (Turley et al., Nature Genetics, Vol. 50, 2018, 229–237). In this brief article, we respond to each of these concerns. Using empirical data, we conclude that our MTAG results do not suffer from ‘inflation in the FDR [false discovery rate]’, as suggested by Hill (Twin Research and Human Genetics, Vol. 21, 2018, 84–88), and are not ‘more relevant to the genetic contributions to education than they are to the genetic contributions to intelligence’.

The bulk heterojunction morphology of organic solar cells widely controls their device efficiency and stability. Structural order and domain size of the donor phase strongly impact the charge separation efficiency, recombination rates, and the hole percolation through the bulk to the electrode. Herewith, we report a comprehensive study on the control of polymeric order already initiated in solution by the introduction of orthogonal solvent additives to the common solution of anthracene containing poly(p-phenylene-ethynylene)-alt-poly(p-phenylene-vinylene) (PPE-PPV) copolymer, bearing statistically substituted linear octyloxy and 2-ethylhexyloxy side-chains in 1:1 ratio along the backbone (AnE-PVstat), and fullerene derivative phenyl-C61-butyric acid methyl ester (PCBM). The first solvent, a 1:1 blend of chlorobenzene and chloroform, had been discovered to promote phase separation in solution and deposited films. This effect could be further enhanced and was precisely controlled by addition of methanol to the common solution in various volume fractions. Thus the ability to transfer the polymer aggregates from the solution into films was applied to solar cells and is investigated in detail.

Zirconolite glass-ceramics are being developed as potential wasteforms for the disposition of Pu wastes in the UK. Previous studies utilised a variety of surrogates whilst this work uses both cold-press and sinter and hot isostatic press methods to validate the wasteform with PuO2. A cold press and sinter sample was fabricated as part of a validation study for plutonium incorporation in hot isostatically pressed (HIPed) wasteforms. The results confirmed the cold-press and sinter, achieved successful waste incorporation and a microstructure and phase assemblage that was in agreement with those expected of a HIPed equivalent. A HIP sample was fabricated of the same composition and characterised by SEM and XRD. Results were in agreement with the sintered sample and achieved complete waste incorporation into the glass-ceramic wasteform. These samples have demonstrated successful incorporation of PuO2 into glass-ceramic HIPed wasteforms proposed for processing Pu-based waste-streams in the UK.

Quality and safety in healthcare, as an academic discipline, has made significant progress over recent decades, and there is now an active and established community of researchers and practitioners. However, work has predominantly focused on physical health, despite broader controversy regarding the attention paid to, and significance attributed to, mental health. Work from both communities is required in order to ensure that quality and safety is actively embedded within mental health research and practice and that the academic discipline of quality and safety accurately represents the scientific knowledge that has been accumulated within the mental health community.

The current study sought to advance our understanding of transactional processes among maternal depression, neighborhood deprivation, and child conduct problems (CP) using two samples of low-income families assessed repeatedly from early childhood to early adolescence. After accounting for initial levels of negative parenting, independent and reciprocal effects between maternal depressive symptoms and child CP were evident across both samples, beginning in early childhood and continuing through middle childhood and adolescence. In addition, neighborhood effects were consistently found in both samples after children reached age 5, with earlier neighborhood effects on child CP and maternal depression found in the one exclusively urban sample of families with male children. The results confirm prior research on the independent contribution of maternal depression and child CP to the maintenance of both problem behaviors. The findings also have implications for designing preventative and clinical interventions to address child CP for families living in high-risk neighborhoods.

The response of platform reefs to sea-level stabilization over the past 6 ka is well established for the Great Barrier Reef (GBR), with reefs typically accreting laterally from windward to leeward. However, these observations are based on few cores spread across reef zones and may not accurately reflect a reef's true accretional response to the Holocene stillstand. We present a new record of reef accretion based on 49 U/Th ages from Heron and One Tree reefs in conjunction with re-analyzed data from 14 reefs across the GBR. We demonstrate that hydrodynamic energy is the main driver of accretional direction; exposed reefs accreted primarily lagoon-ward while protected reefs accreted seawards, contrary to the traditional growth model in the GBR. Lateral accretion rates varied from 86.3 m/ka–42.4 m/ka on the exposed One Tree windward reef and 68.35 m/ka–15.7 m/ka on the protected leeward Heron reef, suggesting that wind/wave energy is not a dominant control on lateral accretion rates. This represents the most comprehensive statement of lateral accretion direction and rates from the mid-outer platform reefs of the GBR, confirming great variability in reef flat growth both within and between reef margins over the last 6 ka, and highlighting the need for closely-spaced transects.

Several studies suggest that neighborhood deprivation is a unique risk factor in child and adolescent development of problem behavior. We sought to examine whether previously established intervention effects of the Family Check-Up (FCU) on child conduct problems at age 7.5 would persist through age 9.5, and whether neighborhood deprivation would moderate these effects. In addition, we examined whether improvements in parent–child interaction during early childhood associated with the FCU would be related to later reductions in child aggression among families living in the highest risk neighborhoods. Using a multisite cohort of at-risk children identified on the basis of family, child, and socioeconomic risk and randomly assigned to the FCU, intervention effects were found to be moderated by neighborhood deprivation, such that they were only directly present for those living at moderate versus extreme levels of neighborhood deprivation. In addition, improvements in child aggression were evident for children living in extreme neighborhood deprivation when parents improved the quality of their parent–child interaction during the toddler period (i.e., moderated mediation). Implications of the findings are discussed in relation to the possibilities and possible limitations in prevention of early problem behavior for those children living in extreme and moderate levels of poverty.

Background: A previous study (Gauntlett-Gilbert and Kuipers, 2005) has suggested that distress associated with complex visual hallucinations (CVHs) in younger adults with psychosis may more strongly relate to appraisals of meaning than to the content of the hallucination. However, visual hallucinations are most commonly seen in the disorders of later life, where this relationship has not been investigated. Aim: To establish if there is a relationship between appraisals of CVHs and distress in older, non-psychotic people with CVHs. Method: All variables were measured using a semi-structured interview and were compared between a high distress group (n = 16) and a low distress group (n = 19). Results: The high distress group rated their hallucinations as more malevolent and omnipotent, with greater negative implications for physical and mental health. There was no significant difference between groups on ratings of hallucination content (independently rated), frequency, awareness or control. Conclusion: Appraisals of CVHs are linked to distress.
