Objective:
Late Life Major Depressive Disorder (LLD) and Hoarding Disorder (HD) are common in older adults with prevalence estimates up to 29% and 7%, respectively. Both LLD and HD are characterized by executive dysfunction and disability. There is evidence of overlapping neurobiological dysfunction in LLD and HD suggesting potential for compounded executive dysfunction and disability in the context of comorbid HD and LLD. Yet, prevalence of HD in primary presenting LLD has not been examined and potential compounded impact on executive functioning, disability, and treatment response remains unknown. Thus, the present study aimed to determine the prevalence of co-occurring HD in primary presenting LLD and examine hoarding symptom severity as a contributor to executive dysfunction, disability, and response to treatment for LLD.
Participants and Methods:Eighty-three adults ages 65-90 participating in a psychotherapy study for LLD completed measures of hoarding symptom severity (Savings Inventory-Revised: SI-R), executive functioning (WAIS-IV Digit Span, Letter-Number Sequencing, Coding; Stroop Interference; Trail Making Test-Part B; Letter Fluency), functional ability (World Health Organization Disability Assessment Schedule-II-Short), and depression severity (Hamilton Depression Rating Scale) at post-treatment. Pearson's Chi-squared tests evaluated group differences in cognitive and functional impairment rates and depression treatment response between participants with (HD+LLD) and without (LLD-only) clinically significant hoarding symptoms. Linear regressions were used to examine the association between hoarding symptom severity and executive function performance and functional ability and included as covariates participant age, years of education, gender, and concurrent depression severity.
Results:At post-treatment, 24.1% (20/83) of participants with LLD met criteria for clinically significant hoarding symptoms (SI-R.41). Relative to LLD-only, the LLD+HD group demonstrated greater impairment rates in Letter-Number Sequencing (χ2(1)=4.0, p=.045) and Stroop Interference (χ2(1)=4.8, p=.028). Greater hoarding symptom severity was associated with poorer executive functioning performance on Digit Span (t(71)=-2.4, β=-0.07, p=.019), Letter-Number Sequencing (t(70)=-2.1, β=-0.05, p=.044), and Letter Fluency (t(71)=-2.8, β=-0.24, p=.006). Rates of functional impairment were significantly higher in the LLD+HD (88.0%) group compared to the LLD-only (62.3%) group, (χ2(1)=5.41, p=.020). Additionally, higher hoarding symptom severity was related to greater disability (t(72)=2.97, β=0.13, p=.004). Furthermore, depression treatment response rates were significantly lower in the LLD+HD group at 24.0% (6/25) compared to 48.3% (28/58) in the LLD-only group, χ2(1)=4.26, p=.039.
Conclusions:The present study is among the first to report prevalence of clinically significant hoarding symptoms in primary presenting LLD. The findings of 24.1% co-occurrence of HD in primary presenting LLD and increased burden on executive functioning, disability, and depression treatment outcomes have important implications for intervention and prevention efforts. Hoarding symptoms are likely under-evaluated, and thus may be overlooked, in clinical settings where LLD is identified as the primary diagnosis. Taken together with results indicating poorer depression treatment response in LLD+HD, these findings underscore the need for increased screening of hoarding behaviors in LLD and tailored interventions for this LLD+HD group. Future work examining the course of hoarding symptomatology in LLD (e.g., onset age of hoarding behaviors) may provide insights into the mechanisms associated with greater executive dysfunction and disability.

Health disparities between Appalachia and the rest of the country are widening. To address this, the Appalachian Translational Research Network (ATRN) organizes an annual ATRN Health Summit. The most recent Summit was held online September 22–23, 2020, and hosted by Wake Forest Clinical and Translational Science Institute in partnership with the Northwest Area Health Education Center. The Summit, titled “Community-Engaged Research in Translational Science: Innovations to Improve Health in Appalachia,” brought together a diverse group of 141 stakeholders from communities, academic institutions, and the National Center for Advancing Translational Science (NCATS) to highlight current research, identify innovative approaches to translational science and community-engaged research, develop cross-regional research partnerships, and establish and disseminate priorities for future Appalachian-focused research. The Summit included three plenary presentations and 39 presentations within 12 concurrent breakout sessions. Here, we describe the Summit planning process and implementation, highlight some of the research presented, and outline nine emergent themes to guide future Appalachian-focused research.

Previous genetic association studies have failed to identify loci robustly associated with sepsis, and there have been no published genetic association studies or polygenic risk score analyses of patients with septic shock, despite evidence suggesting genetic factors may be involved. We systematically collected genotype and clinical outcome data in the context of a randomized controlled trial from patients with septic shock to enrich the presence of disease-associated genetic variants. We performed genomewide association studies of susceptibility and mortality in septic shock using 493 patients with septic shock and 2442 population controls, and polygenic risk score analysis to assess genetic overlap between septic shock risk/mortality with clinically relevant traits. One variant, rs9489328, located in AL589740.1 noncoding RNA, was significantly associated with septic shock (p = 1.05 × 10–10); however, it is likely a false-positive. We were unable to replicate variants previously reported to be associated (p < 1.00 × 10–6 in previous scans) with susceptibility to and mortality from sepsis. Polygenic risk scores for hematocrit and granulocyte count were negatively associated with 28-day mortality (p = 3.04 × 10–3; p = 2.29 × 10–3), and scores for C-reactive protein levels were positively associated with susceptibility to septic shock (p = 1.44 × 10–3). Results suggest that common variants of large effect do not influence septic shock susceptibility, mortality and resolution; however, genetic predispositions to clinically relevant traits are significantly associated with increased susceptibility and mortality in septic individuals.

Academic medical centers (AMCs) face challenges in conducting research among traditionally marginalized communities due to long-standing community mistrust. Evidence suggests that some AMC faculty and staff lack an understanding of the history of distrust and social determinants of health (SDH) affecting their communities. Wake Forest Clinical and Translational Science Institute Program in Community Engagement (PCE) aims to build bridges between communities and Wake Forest Baptist Health by equipping faculty, clinicians, administrators, and staff (FCAS) with a better understanding of SDH. The PCE collaborated with community partners to develop and implement community tours to improve cross-community AMC understanding and communication, enhance knowledge of SDH, and build awareness of community needs, priorities, and assets. Nine day-long tours have been conducted with 92 FCAS. Tours included routes through under-resourced neighborhoods and visits to community assets. Participant evaluations assessed program quality; 89% reported enhanced understanding of access-to-care barriers and how SDH affect health; 86% acknowledged the experience would improve future interactions with participants and patients; and 96% agreed they would recommend the tour to colleagues. This work supports the use of community tours as a strategy to improve cross-community AMC communication, build trust, and raise awareness of community needs, priorities, and assets.

Childhood obesity is a complex and multi-faceted problem, with contributors ranging from individual health behaviors to public policy. For clinicians who treat pediatric obesity, environmental factors that impact this condition in a child or family can be difficult to address in a clinical setting. Community-clinic partnerships are one method to address places and policies that influence a person’s weight and health; however, such partnerships are typically geared toward community-located health behavior change rather than the deeper social determinants of health (SDH), limiting effective behavioral change. Community-engaged research offers a framework for developing community-clinic partnerships to address SDH germane to obesity treatment. In this paper, we discuss the relationship between SDH and pediatric obesity treatment, use of community-clinic partnerships to address SDH in obesity treatment, and how community engagement can be a framework for creating and harnessing these partnerships. We present examples of programs begun by one pediatric obesity clinic using community-engagement principles to address obesity.

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.

Introduction
The Latino population in the United States is rapidly growing and faces profound health disparities; however, engagement of Latinos in biomedical research remains low. Our community-based participatory research partnership has recruited 2083 Spanish-speaking Latinos into 21 studies over 15 years. We sought to identify and describe the strategies we have used to successfully recruit and retain Spanish-speaking Latinos in research.
MethodsWe abstracted and analyzed data from archived study notes, progress reports, team meeting minutes, and in-depth interviews conducted annually from community-based participatory research partnership members. We used a nominal group process to refine and prioritize strategies.
ResultsOverall, 13 recruitment strategies and 12 retention strategies emerged. These strategies relied on the creativity and perseverance of the study team and partners.
ConclusionsIt is essential that we develop and disseminate effective recruitment and retention strategies that engage Latinos in biomedical research to reduce health disparities and promote health equity.

Throughout the tropics, developing countries and territories are highly dependent on nearshore marine resources for food and income, however information on the sustainability and proper management of these fisheries is lacking. In Pohnpei, Micronesia, the sustainability of a coral reef finfishery was assessed by comparing coral reef fish demand to coral reef biocapacity using a marine ecological footprint (MEF) analysis. Based on geo-referenced satellite and aerial imagery, Pohnpei and surrounding atolls have 184.2 km2 of coral reef habitat with a sustainable finfish yield of 573–1118 t yr−1, however total harvest was estimated at 4068 t yr−1, exceeding biocapacity by 360–710%. The MEF was supported by observed impacts to coral reef resources, including (1) long-term declines in fish spawning aggregation density, (2) reductions in mean size, age and fecundity of key commercial species, (3) reliance on undersized fish, and (4) decadal declines in mean size and abundance of fishes of iconic value and critical to ecosystem maintenance. The commercial fishery was responsible for 68% of finfish catch volume, while reef fish consumption, at 93 kg person−1 yr−1, was among the highest in the region. To sustainably meet current demand, up to 833 km2 of additional reef area would be required. The study illustrates the MEF, at least rudimentarily, reflects biological reality on local reefs and represents a valuable analytical tool in a marine policymaker's toolbox.

The Medium-l Program of the Michelson Doppler Imager (MDI) instrument on board SOHO provides continuous observations of oscillation modes of angular degree, l, from 0 to ∼ 300. The initial results show that the noise in the Medium-l oscillation power spectrum is substantially lower than in ground-based measurements. This enables us to detect lower amplitude modes and, thus, to extend the range of measured mode frequencies. The MDI observations also reveal the asymmetry of oscillation spectral lines. The line asymmetries agree with the theory of mode excitation by acoustic sources localized in the upper convective boundary layer. The sound-speed profile inferred from the mean frequencies gives evidence for a sharp variation at the edge of the energy-generating core. In a thin layer just beneath the convection zone, helium appears to be less abundant than predicted by theory. Inverting the multiplet frequency splittings from MDI, we detect significant rotational shear in this thin layer.
