OBJECTIVES/SPECIFIC AIMS: Analyze data from the first 30 children enrolled in a prospective cohort study evaluating the ability of specific serum biomarkers to distinguish children with traumatic brain injuries (TBI) from children with orthopedic injuries (OI). METHODS/STUDY POPULATION: Children ages 0<5 years were eligible if they presented to the emergency department within 6 hours of injury. Children were identified as having a TBI if they sustained a head injury and were found to have an acute injury on head CT. Children were identified as having an OI if they sustained a musculoskeletal injury significant enough to necessitate radiography per clinical care. Individual (eg, age) and clinical (eg, radiography findings) factors, as well as serum biomarkers [eg, ubiquitin C-terminal hydrolase L1 (UCH-L1), glial fibrillary acidic protein (GFAP)] were collected at time of enrollment. TBI and OI groups were compared using Wilcoxon rank-sum and Kruskal-Wallis tests. RESULTS/ANTICIPATED RESULTS: This cohort consisted of 13 children with TBI (7 with isolated skull fractures, 1 with intracranial injury, and 5 with both a skull fracture and an intracranial injury) and 17 with OI (12 with fractures). Most patients were male (67%) and White (67%), and this did not differ between groups (p>0.1). Children with TBI were significantly younger than children with OI, with an average (±standard deviation) age of 15±13 and 39±13 months, respectively (p<0.01). There was not a significant difference in time from injury to biomarker collection between TBI and OI patients at 4.1±1.8 and 5.8±2.6 hours, respectively (p=0.07). Median (IQR) levels of GFAP were significantly higher (p<0.01) in children with TBI, relative to children with OI: 220 (67–421) pg/mL Versus 37 (25–74) pg/mL, respectively. Median (IQR) levels of UCH-L1 were also significantly higher (p<0.01) in the TBI group, relative to children with OI: 444 (377–449) pg/mL Versus 248 (140–417) pg/mL, respectively. In a subanalysis comparing median biomarker levels across three study groups (ie, TBI with an isolated skull fracture, TBI with an intracranial injury, and OI), group differences remained significant for both biomarkers with TBI patients having higher levels, relative to OI patients, of both GFAP (p<0.01) and UCH-L1 (p=0.02). DISCUSSION/SIGNIFICANCE OF IMPACT: GFAP and UCH-L1 hold promise to improve the diagnosis of TBI in very young children. Identification of a marker of TBI that can be done in the acute care setting would advance the diagnosis of TBI in very young children, a vulnerable population for whom identification of neurological symptoms can be challenging.

OBJECTIVES/GOALS: The Michigan Institute for Clinical & Health Research Community Engagement (MICHR CE) has collaborated for 15+ years with underserved communities on public health issues. As Michigan’s sole CTSA institution, we aim to advance the science of community engagement in translational science statewide. METHODS/STUDY POPULATION: MICHR CE PACE (Promoting Academic-Community Engagement) will advance clinical and translational science. Key steps include: 1) form a PACE Steering Committee; 2) PACE Trainings with community-academic partner Detroit Urban Research Center; 3) PACE Training Manual; 4) community Grand Rounds to bridge academic-community insights; and 5) community resources (e.g., toolkits). PACE projects will spotlight community-engaged research (CEnR) via diverse media including social media and community-level communications. The PACE ScienCE initiative will embody cultural humility by addressing power imbalances, emphasizing trust. We will utilize assessments and root cause analyses to navigate CEnR barriers. RESULTS/ANTICIPATED RESULTS: Anticipated results from MICHR CE’s planned approach with PACE include strengthened academic-community relationships. Formation of the PACE Steering Committee and collaborations are expected to foster more structured and impactful CEnR trainings. The PACE Training Manual will become a foundational resource for CEnR best practices. Community Grand Rounds will reveal increased interdisciplinary insights and community trust. All PACE projects will utilize diverse media to enhance CEnR visibility and community-level access. Lastly, by addressing power disparities via PACE ScienCE, we foresee enhanced trust, reduced barriers, and more transparent community-academic collaborations. DISCUSSION/SIGNIFICANCE: This strategy, based on co-planned efforts and community consultations, aims to reshape Michigan’s CEnR landscape and offers a replicable model for other regions. The insights gained will guide community-academic collaborations promoting translational, inclusive, and efficient community engagement.

OBJECTIVES/GOALS: Familial Hypercholesterolemia (FH) is a common disorder that is vastly underdiagnosed and causes an increased risk for sudden cardiac death. Cardiology providers (CHCPs) are in an ideal position to care for patients with FH. This research aimed to understand the practice behaviors of CHCPs in the screening, diagnosis, and management of FH. METHODS/STUDY POPULATION: An explanatory mixed methods design was utilized for this study. Adaptation of an existing FH knowledge tool guided survey development. The results of the quantitative survey, along with the Knowledge to Action framework and Theory of Planned Behavior, guided development of the interview protocol. Convenience and snowball sampling recruited CHCPs in the Division of Cardiology at Columbia University Irving Medical Center (CUIMC). Descriptive statistical analysis was performed on survey data. Qualitative interviews were conducted with survey respondents who volunteered to participate. Interviews were audio recorded, transcribed, and analyzed thematically. A descriptive review of the educational materials offered by the Division of Cardiology was conducted to identify FH knowledge domains presented. RESULTS/ANTICIPATED RESULTS: CHCPs with MDs, at CUIMC for 6-10 years, in clinical practice for 1-5 years, and in Inpatient Services had the highest average total FH knowledge scores. CHCPs with RNs, at CUIMC for less than 1 year, in clinical practice for 6-10 years, and in Cath Lab had the lowest average FH knowledge scores. Twenty interviews were completed, and four themes emerged- variability in FH care; issues related to addressing FH at institutional, practice setting and individual levels; importance of identifying FH early; and intervention approaches to overcome barriers to caring for FH patients in cardiology. CHCPs with MDs or with experiential FH knowledge were the only CHCPs to describe FH care beyond the point of screening. The document review revealed that only MDs were provided four lectures over the course of 4 years pertaining to FH. DISCUSSION/SIGNIFICANCE: CHCPs with didactic or experiential FH knowledge provided care beyond screening. Future interventions should increase didactic and experiential FH knowledge by incorporating institutional, local, and national FH resources. Improving the FH care CHCPs provide, can reduce FH-related morbidity and mortality as well as improve FH health outcomes.

ABSTRACT IMPACT: This poster will demonstrate how input from a CTSI Community Advisory Board was used to develop a large, annual dissemination event focused on health disparities, health equity, and community engagement. OBJECTIVES/GOALS: The NYU Langone Annual Health Disparities Symposium began in response to the NYU-H+H CTSI’s Community Advisory Board, which expressed a desire to 1) learn about health disparities research at NYU, H+H, and beyond; 2) build connections and interdisciplinary collaborations; 3) support bidirectional dissemination between community and researchers. METHODS/STUDY POPULATION: The annual symposium, a collaboration between NYU Langone’s CTSI, Department of Population Health, Office of Diversity Affairs, and the NYU-CUNY Prevention Research Center, features a keynote, a series of rapid-fire talks, panels on current controversies in population health and the work of the Community Engagement Cores of NYC-based CTSAs, and poster sessions. Each year the event is focused around a specific theme, with the 2020 theme being ‘Research Into Action’. Audience members include faculty, staff, students, health care providers, community health workers, and representatives from community-based organizations, health care facilities, and the NYC Department of Health and Mental Hygiene. For the very first time, the event was held virtually days and CME/CNE credits were provided free of cost. RESULTS/ANTICIPATED RESULTS: The conference explored how institutions have turned research into action, and speakers addressed the ways in which COVID-19 has highlighted structural inequities that have existed across time. 585 attendees participated in the event, with 63 claiming an average of 7.8 hours of continuing education credits. 46 individuals completed the post-event evaluation, with 95% agreeing/strongly agreeing that the symposium increased their awareness of health disparities research taking place at NYU, H+H, and beyond, 91% agreeing/strongly agreeing that they are likely to apply the information learned to their own work, and 91% agreeing/strongly agreeing that the symposium increased their interest in health disparities research. 86% were very/extremely satisfied with the quality of the meeting overall. DISCUSSION/SIGNIFICANCE OF FINDINGS: The 2020 event had the greatest proportion of health care provider attendees (24%), likely due to the opportunity to earn CME/CNE credits. Attendance also grew over the years, from 150 in 2015 to 585 in 2020. This increase is likely due to increased awareness of the event, as well as well as virtual the format, which made it more convenient for attendees.

OBJECTIVES/SPECIFIC AIMS: Community health coalitions (CHC) aim to improve local cultures of health, health behaviors, and health outcomes. However, challenges sustaining partnerships and activities limit CHC impact. Traditional CHC evaluations survey members about perceived effectiveness, failing to capture underlying network structures and community health outcomes. Thus, we applied a mixed-methods evaluation in eight rural Indiana CHC, triangulating social network analysis [(SNA), conducted in 2017], functioning effectiveness [Coalition Self-Assessment Survey (CSAS), also 2017], and latest county health statistics (2015–2016) to assess existing CHC building efforts, inform best practices, and facilitate the adoption of evidence-based programming. METHODS/STUDY POPULATION: Across the eight rural Indiana CHC, relationships between the three evaluation components were analyzed using Pearson’s correlations. We are now collaborating with Purdue’s Nutrition Education Program Community Wellness Coordinators to scale up evaluation efforts throughout Indiana. RESULTS/ANTICIPATED RESULTS: CHC effectiveness was positively correlated with the average number of connections CHC members held in the network (mean indegree) and negatively correlated with the presence of a network broker (eigenvector centrality). However, effective leadership was positively correlated with opioid deaths and treatment, food insecurity, smoking during pregnancy, lack of healthcare coverage, and fair/ poor health status, and negatively correlated with prenatal care. Effective operating norms was positively correlated with smoking during pregnancy and preterm births, and negatively correlated with prenatal care. Effective action outcomes was positively correlated with opioid deaths and treatments, smoking during pregnancy, preterm births, and fair/ poor health status, and negatively correlated with respondents reporting they had no personal doctor. DISCUSSION/SIGNIFICANCE OF IMPACT: Interestingly, CHC effectiveness was positively correlated with poor county health outcomes related to infant well-being. Thus, CHC may develop in counties with a high unmet need for effective pregnancy and infant services. Alternatively, the prevalent CHC focus on obesity prevention may eclipse programmatic efforts to improve infant well-being. Longitudinal evaluations and scaling up evaluation efforts across Indiana are being pursued to clarify trajectories and inform best practices, which in turn should provide recommendations for network structures to improve CHC effectiveness and county health.

OBJECTIVES/SPECIFIC AIMS: Cervical fusion is commonly performed for the management of degenerative disc disease, which can cause spinal stenosis and radiculopathy. Adjacent segment disease (ASD) is an adverse postsurgical outcome experienced by some patients as new radiculopathy, stenosis, or other symptomatic sequelae. We sought to assess whether fusion extension past the cervicothoracic junction reduces the risk of distal ASD after multilevel fusions ending at C7-T3. METHODS/STUDY POPULATION: We retrospectively reviewed all first-time patients undergoing instrumented cervical fusion of at least 2 spinal levels and whose distal level of fusion ranged from C7-T3, at the Johns Hopkins Medical Institutions, from 1999 to 2013. The primary outcome was reoperation for distal ASD. Using multiple logistic regression, ANOVA, and χ2 analysis, we determined the odds of ASD due to age, gender, distal level of fusion, surgical approach (anterior, posterior, or combined), smoking status, and race. RESULTS/ANTICIPATED RESULTS: Of the 158 patients who met the selection criteria, the mean age was 58.7±13.8 years, and 95 (60.1%) were female. Ten patients (6.3%) underwent reoperation for ASD. Patients whose fusions ended at C7 were significantly more likely to develop ASD and undergo reoperation (70%, p=0.007) than those whose fusions ended at T1. There were no differences in age, proximal fusion level, smoking status, BMI, gender, and patient-reported race between the reoperation and non-reoperation groups. Following a multivariable analysis, extending the distal fusion to T1 was again found to be protective against reoperation (OR=0.07, p=0.020). DISCUSSION/SIGNIFICANCE OF IMPACT: Our study shows that for multilevel instrumented cervical fusions that terminate within the cervicothoracic junction, fusion distal to the C7 vertebra is associated with decreased odds of reoperation for symptomatic ASD. Therefore, this study provides clinical evidence that may help surgeons determine the optimal distal fusion segment for multilevel fusions ending at C7-T3.

OBJECTIVES/GOALS: The primary goals of this study are 1) expand our understanding of the neural circuitry influenced by the neuropeptide Neuromedin U (NMU) via its receptor Neuromedin U Receptor 2 (NMUR2), and 2) provide alternative top-down mechanisms for how NMU regulates high fat food intake and cocaine taking. METHODS/STUDY POPULATION: Immunohistochemistry (IHC) for NMUR2 and cell markers was performed on rat brain tissue containing the medial prefrontal cortex (mPFC). To identify the source of the presynaptic NMUR2, anterograde tracing from the paraventricular nucleus or dorsal raphe nucleus to the mPFC utilizing an AAV2- dsRed-synaptobrevin fusion protein were performed (n=3) and will be followed by IHC. Using in vivo calcium imaging technology (InScopix nVista), neuronal activity (calcium transients) was recorded from the mPFC of two awake, freely behaving rats. Each animal underwent a single session of 30 minutes baseline activity, intraperitoneal NMU administration, and 30 minutes of post-treatment activity. Activity was then processed and recorded as distinct events using the InScopix data acquisition software. RESULTS/ANTICIPATED RESULTS: Medial prefrontal cortex staining for NMUR2 revealed a characteristic “beads on a string” motif, consistent with presynaptic receptor expression. Furthermore, we expect the anterograde tracing experiment will show colocalization of the dsRed-synaptobrevin fusion protein with NMUR2 on synaptic inputs into the medial prefrontal cortex. Following quantification of pre- and post- treatment events using the InScopix data acquisition software, total events during the pre- and post-treatment time periods were calculated. In these studies, both animals demonstrated a clear increase in calcium transient activity between pre- and post- treatment evaluations, suggesting that NMU administration increases the neuronal activity of neurons in the prefrontal cortex. DISCUSSION/SIGNIFICANCE: This research provides a new site of action for the known therapeutic effects of NMU. We demonstrate the presence of presynaptic NMUR2 in the mPFC and show that systemic administration of NMU increases mPFC neuronal activity. This illustrates NMU may act as a top-down mediator for substance use disorders and binge eating behaviors.

OBJECTIVES/GOALS: The effect of the Direct-Acting Antiviral (DAA) on hepatic histopathological features from patients treated for HCV has not been thoroughly evaluated. The goals of this retrospective study were to determines differences between the liver biopsies collected before and after DAA treatment and correlated the histopathology with clinical outcome. METHODS/STUDY POPULATION: Spectral imaging was used to evaluate differences in intrahepatic macrophage (CD68, CD14, CD16, MAC 387, and CD163) and T cell (CD3, CD4, CD8, CD45, and FoxP3) phenotypes in paired liver biopsies collected from the same patient before (n=10) and after (n=10) achieving SVR (Figure 1). Imaging analysis and machine learning algorithms were used to evaluate changes in these key immune cells. We also compared differential gene expression of over 700 genes using RNA isolated from liver biopsies with NanoString. RESULTS/ANTICIPATED RESULTS: Multispectral imaging analysis showed a significant increase of proinflammatory/M1-like (e.g., CD14+) and anti-inflammatory/M2-like macrophage (e.g., CD163+) phenotypes in pre-treatment versus post-treatment biopsies, respectively. Gene expression analysis revealed enrichment of inflammatory (HLA-B, STAT1, CXCL10) and interferon induced-antiviral (ISG15, OAS3, MX1 and IFIT1) genes in the pre-treatment vs the post-treatment group. Cell deconvolution analysis also showed a significant increase of M1-like macrophages in the pre-treatment group when compared to the post-treatment group or controls. Upregulation of genes associated with cell proliferation and differentiation (c-KIT and Fos) was observed in the post-treatment biopsies of patients with persistent inflammatory infiltrates. DISCUSSION/SIGNIFICANCE: Protein and gene expression profiles observed in patients before DAA therapy showed a strong macrophage-mediated inflammatory response against HCV infection in the liver that shifted significantly to a tissue remodeling microenvironment after treatment.

OBJECTIVES/SPECIFIC AIMS: Our overall goals are: 1. To engage, inform and educate children and families on clinical research and increase their understanding of the goals and process of participation in research studies/clinical trials; 2. To Increase participation of children, especially those who are disproportionately underrepresented, in clinical research in the Western New York region and beyond. METHODS/STUDY POPULATION: The University at Buffalo Clinical Translational Science Institute conducted meetings in schools, community coalitions while holding focus groups with children with chronic conditions and their families and community health workers to identify the general perceptions of research. These conversations then informed the development of a children’s activity book about research. Completed in 2017, our “Sofia Learns about Research” activity book presents research in a non-threatening way by presenting a child with asthma who walks through the process of learning about research, being recruited and participating in research. The book explains basic concepts about research coupled with fun games and the possibility to color. Over 1,000 copies of the activity book have been disseminated to second to fourth graders via afterschool programs, community events, and medical practice waiting rooms. Recipients of the book are directed to short surveys to provide feedback on the book and their perception of research. The parents are also given the option to sign-up for the Buffalo Research Registry in order to be contacted about research opportunities. RESULTS/ANTICIPATED RESULTS: Response has been very positive, with parents and community participants saying “It’s not just a storybook. The activities keep kids entertained while learning new concepts.” In children informally polled via a brief questionnaire pre and post story reading at an afterschool program, there was an increase in those interested in participating in a research study. In a recent event sponsored by the CTSI Community Engagement Core and other UB organizations, a group of fifty children from diverse background colored with enthusiasm several activity pages and obtained stickers for their “Research Passport”. In a recent teacher focus group we learned that the book content may fit the Science Curriculum and plan on reading sessions in inner-city schools after approval from the district. A pilot reading activity in a Montessori program revealed that second grade children were able to understand and complete the activities in the book. We are obtaining further feedback form teachers and parents in order to design simple protocol to be submitted for IRB approval to obtain more formal feed-back and outcomes in future readings. In parents and focus groups several respondents have indicated its relevance to older populations and English-language learners as well. The book has recently been translated into Spanish and Arabic through a partnership with the International Institute of Buffalo, which “welcomes, connects and empowers the foreign born”. Some of the book’s images have been modified in order to be sensitive to the readers’ culture and we are in the process of collaborating with the International Institute to disseminate it to their clients. We are in the initial phase of planning a mobile application which we anticipate will significantly enhance dissemination. DISCUSSION/SIGNIFICANCE OF IMPACT: This presentation will describe the development process, the underpinning concepts and our plans and current progress towards a more formal community and school dissemination and evaluation. This project was made possible by Team Science in that the expertise of a millennial pre-medical student and an anthropologist with high community involvement was coupled with that of a senior clinical translational researcher. Moreover, much research and attention was devoted to the creation of images that are culturally inclusive. To this end, with the exception of the cover page, we have intentionally created the book in black and white so that the child may use his/her imagination and color the way he/she sees the protagonists and the environment. Great attention was devoted to names of the protagonists with the names of the two main characters being among the most common in the world in numerous countries. Also, the book lends itself to a mobile application which will allow the reader to change colors and shapes of the protagonists to fit his/her cultural background. We are in the early planning stages and will share our progress as part of this presentation. We have strived to disseminate the book with a broad approach in our community. This phase is being followed by a more formal dissemination phase via libraries, schools and community events. This part of the project exemplifies the challenge between wanting to disseminate the book broadly while obtaining formal feedback and outcomes in compliance with regulations protecting the anonymity and/or confidentiality of children and families. Therefore for this second phase of dissemination IRB approval is being sought in order to collect more quantitative and qualitative data on the impact of the book. We have already conducted a focus group with teachers to overcome the challenges around informed consent, especially in the public school system. Our initial findings suggest this resource will improve knowledge and perception of research among children and their families. To our knowledge most of the materials explaining research to children are geared to older children and are often sponsored by pharmaceutical companies for a specific trial. If successful, this book can have a profound impact in reaching out to children outside of the research and medical environments, with the ultimate goal of increasing the child’s and family’s willingness to participate in clinical research and clinical trials.

ABSTRACT IMPACT: This work provides context from the patient perspective on the impact of hospital policies on their birthing experiencing during the first peak of the pandemic. OBJECTIVES/GOALS: The goal of this study was to report the intrapartum care experiences from people giving birth during the COVID-19 pandemic in the United States. Place of birth included hospital, birth center and home births. METHODS/STUDY POPULATION: Studies that involved patient-related data collection are hindered by pandemic-related changes in clinical practices and research policies. Our aim was to assess patient experience during a pandemic, we explored data collection via a large online community of pregnant women. We asked if women who birthed during COVID-19 changed their birth setting and if they experienced less respectful care, more pressure to undergo induction and/or cesarean birth and newborn separation. We also wanted to explore whether there were differences in the care experience depending on the race of the woman. Open ended questions on care experiences were included and content analysis conducted. Bivariate analysis was conducted comparing those from high versus less COVID-19 impacted areas and by race (White/Black self-identifying). RESULTS/ANTICIPATED RESULTS: The mean age was 31.5 years (SD = 5.0), 80.7% identified as White, 85.0% married, and 85.3% privately insured (N=388). Bivariate unadjusted analyses comparing high vs. low impact COVID-19 states, 22.3% considered changing their place of birth versus 12.7% in less impacted areas (p<.05): no difference pressure for induction/cesarean based on region. In bivariate unadjusted analysis comparing White and Black people, Black people had higher odds of pressure for cesarean or induction compared to White (OR 10.3, 95% CI 2.2 to 48.6, p=.0003). Black people had lower respect scores vs. White (68.7 vs. 72.3 p<.01) and higher odds of preterm birth 3.7 (1.1 to 12.4, p=0.04). Content analysis themes were institutional policies, changes in care, hospital staff interactions, sub-par care, support during birth and mental health. DISCUSSION/SIGNIFICANCE OF FINDINGS: The analysis demonstrated differences among participants from highly versus less impacted COVID-19 states. Disparities persisted with Black women reporting lower respect, pressure for interventions and more preterm birth when compared to White participants. Limitations include use of a convenience sample and self-reported data.

OBJECTIVES/GOALS: Kidney transplant is superior to dialysis for the treatment of end-stage kidney disease, but accessing transplant requires high patient engagement. We sought to develop a group counseling intervention with patients and their social support members using an evidence-based, stakeholder-engaged approach. METHODS/STUDY POPULATION: We employed an Intervention Mapping approach to incorporate qualitative data from stakeholders on barriers to accessing kidney transplant. Data were collected from 13 focus groups of African American (AA) and white adult kidney transplant candidates and their social support networks in Minnesota and Georgia. We completed this process through (1) qualitative data collection, (2) utilizing data and intervention mapping methods to develop a conceptual framework to describe associations between behavioral determinants and desired outcomes, and (3) using these products to identify evidence-based approaches to modify behavioral determinants through a theory based intervention. RESULTS/ANTICIPATED RESULTS: Participants describe experiences of overwhelm, isolation, helplessness, and difficulty communicating. In addition, AA participants expressed distrust in the medical system. We systematically incorporated these themes into a conceptual model of behavior change that identifies determinants of necessary actions to obtain transplant, including knowledge, self-efficacy, reduced decisional conflict, and perception of social support. Evidence-based methods to modify these determinants, such as modeling, goal-setting, and mobilizing social support, were incorporated into the design of a group education and counseling intervention with an individualized risk calculator. DISCUSSION/SIGNIFICANCE OF IMPACT: Intervention mapping allows for behavior change theories to be incorporated into counseling sessions with patients and their social support networks. This approach translates qualitative data into an evidence-based intervention which will be piloted in a randomized controlled trial (RCT) to determine feasibility for a larger RCT.

OBJECTIVES/GOALS: Early HIV detection and treatment are key to reducing patient morbidity and mortality, yet 40% of people living with HIV do not know their status. “OPT-OUT” approaches to hiv testing, in which patients #_MSOCOM_1 are informed that an HIV test will be conducted unless they decline, are being increasingly recognized as a means to increase HIV testing. METHODS/STUDY POPULATION: the ed at Uhealth tower (UHT) implemented #_MSOCOM_1 the focus program that integrates routine “opt-out” HIV screening into the existing electronic medical record workflow to increase the number of individuals who know their HIV status, optimize linkage to care, and reduce stigma associated with HIV. the emr facilitates the opt-out screening model and maximizes the use of information systems to seamlessly integrate screening as a routine practice in a high-volume ed. our partnership with the florida department of health in miami dade (FDOH) allows uht to verify whether cases are new or known /out-of-care, link individuals immediately to care, and increase efficiencies with real-time data reconciliation. RESULTS/ANTICIPATED RESULTS: since implementation#_MSOCOM_1, from October 2019 - Dec 2022, the UHT ED screened 34, 314 eligible patients for HIV, of which, 17, 850 were tested. 228 people with hiv were identified; 37 were newly diagnosed. of HIV+ Diagnoses, 54.67% of HIV+ individuals were black and 36.89% HISPANIC. HIV+ individuals were referred to the doh with linkage to care at 81%. comparatively, before the onset of focus, the ED ordered 38 HIV tests, with one positive from Oct 2018 TO Sept. 2019. DISCUSSION/SIGNIFICANCE: UHT ED’s focus “OPT-OUT” HIV testing is a valuable conduit for HIV detection, prevention, and care. OPT-OUT screening removes the stigma associated with hiv testing, fosters earlier diagnoses and treatment, reduces health disparities, and decreases the risk of transmission.

OBJECTIVES/SPECIFIC AIMS: We will use a structured evaluation framework, the payback framework, to document the outcomes of 15 case studies of pilot projects supported by Georgia CTSA from 2007 to 2014. METHODS/STUDY POPULATION: We will use a case study approach including bibliometric analyses of publications associated with the selected projects, document review (e.g., investigator curriculum vitae, biannual project reports) and investigator interviews. RESULTS/ANTICIPATED RESULTS: We will document outcomes in 5 “payback categories”: (1) knowledge, (2) research targeting, capacity building, and absorption, (3) policy and product development, (4) health benefits, and (5) broader economic benefits. DISCUSSION/SIGNIFICANCE OF IMPACT: This study will aid in characterizing the returns resulting from this research funding and identify its strengths and weaknesses. This study will inform our understanding of the diversity and breadth of outcomes resulting from Georgia CTSA-supported research, and the value pilot projects provide to clinical and translational science and the broader community.

In recent years, there have been concerted efforts to better recruit, support, and retain diverse faculty, staff, and trainees in academic medicine. However, many institutions lack comprehensive and strategic plans to provide support to retain and recruit individuals from historically underrepresented groups. In this article, we itemize specific mechanisms through which institutions can support diverse individuals with the goal of improving inclusion and belonging in the workforce to better reflect the diversity of the intended patient and research participant population.

Health systems currently underutilize systematic reviews. Here, we describe a proof of concept project designed to augment the standard systematic review process by presenting qualitative information as a companion to a review on deprescribing interventions. We conducted a thematic analysis of semi-structured interviews with Veterans Health Administration clinicians and Veterans to describe first-hand experiences of engaging in the deprescribing process. Qualitative findings were incorporated into an interactive, web-based product designed to supplement the systematic review report. Preliminary evaluation suggests that integration of narratives as a companion to systematic reviews is of interest to frontline clinicians, researchers, and health system administrators.

The Community Research Liaison Model (CRLM) is a novel model to facilitate community-engaged research (CEnR) and community–academic research partnerships focused on health priorities identified by the community. This model, informed by the Principles of Community Engagement, builds trust among rural communities and expands capacity for community and investigator-initiated research. We describe the CRLM development process and how it is operationalized today. We followed a multi-phase process to design and implement a community engagement model that could be replicated. The resulting CRLM moves community–academic research collaborations from objectives to outputs using a conceptual framework that specifies our guiding principles, objectives, and actions to facilitate the objectives (i.e., capacity, motivations, and partners), and outputs. The CRLM has been fully implemented across Oregon. Six Community Research Liaisons collectively support 18 predominantly rural Oregon counties. Since 2017, the liaison team has engaged with communities on nearly 300 community projects. The CRLM has been successful in facilitating CEnR and community–academic research partnerships. The model has always existed on a dynamic foundation and continues to be responsive to the lessons learned by the community and researchers. The model is expanding across Oregon as an equitable approach to addressing health disparities across the state.

OBJECTIVES/SPECIFIC AIMS: Objectives: Decreasing costs and increasing evidence for clinical utility have contributed to whole genome sequencing (WGS) becoming a clinical reality. While previous studies have surveyed the attitudes of patients and community members towards specific gene tests, an emerging literature has begun to describe the preferences of diverse recipients for WGS results. In this study, we sought to identify and synthesize the quantitative evidence on preferences for results from WGS using a systematic review of the literature. METHODS/STUDY POPULATION: We conducted a search of articles on PubMed including subject index terms WGS, whole exome sequencing, genome sequencing, secondary findings, incidental findings, attitudes, preferences, choices, utilities, stated-preferences, discrete choice experiment, and willingness-to-pay. We conducted 11 formal searches to refine the strategy and conducted a final search in December 2017. Duplicates were eliminated and a title and abstract review was conducted to select articles meeting inclusion criteria. RESULTS/ANTICIPATED RESULTS: Our search strategy identified 79 publications meeting initial search criteria with 30 manuscripts meeting inclusion criteria. Of these, most studies were conducted with patient-participants enrolled in existing sequencing studies, while few engaged members of the general public. Of the studies conducted on patients, most were on the medical setting of cancer and related syndromes. The earliest publication date of a manuscript meeting our inclusion criteria was in 2012, yet the majority were published in 2015 or later. DISCUSSION/SIGNIFICANCE OF IMPACT: Between 2012 and 2015, we saw an increasing focus in the medical literature on understanding public and patient preferences for return of results from WGS and WES. Both public and patient populations participating in surveys expressed preferences for receiving results from next-generation sequencing, even if the results are secondary or incidental findings unrelated to the primary indication for sequencing. A primary factor related to patient interest in incidental or secondary findings is the extent to which these results can inform medical intervention. Few studies surveyed representative population-based samples, and this may be an area for future investigation.

OBJECTIVES/SPECIFIC AIMS: This study seeks to understand the relationship between opioid prescribing and patient satisfaction among non-surgical, hospitalized patients. As part of this study, we qualitatively examined challenges in delivering safe and patient-centered care through voices of physicians’, and nurses.’ METHODS/STUDY POPULATION: We collected data through in-person interviews using semi-structured guides tailored to the informant roles. Study participants came from 1 healthcare system located in a mid-Western state. Each interview lasted 30–45 minutes, was audio-recorded with consent, and transcribed for analysis. Two researchers each coded 17 transcripts for discussions around patient-centeredness (including patient satisfaction, patient experiences), and patient safety for hospitalized patients experiencing pain. Analysis followed a general inductive approach, where researchers identified themes related to the research questions using an open coding technique. They discussed and reached consensus on all codes, and extracted several preliminary themes. The analysis was supported by NVivo software. RESULTS/ANTICIPATED RESULTS: The following themes emerged: (1) complex decision-making process to prescribe opioids for hospitalized patients; (2) the role of objective findings in prescribing decisions; (3) bargaining process in prescribing opioids; (4) balancing patient-centeredness and patient safety for selected populations; (5) opioids are the predominant medications for pain care. DISCUSSION/SIGNIFICANCE OF IMPACT: Clinicians’ decision to prescribe opioids for nonsurgical hospitalized patients is based on multiple factors, including patient’s condition, patient’s preference for pain medications, or standard hospital’s pain care regimen. Interventions that improve clinicians’ ability to prescribe opioids may be needed to improve delivery of patient-centered and safe pain care.

OBJECTIVES/GOALS: Maternal undernutrition, a form of malnutrition, can alter neonatal leptin signaling and result in metabolic dysfunction in adulthood. We developed a mild undernutrition model to relate more to societys nutritional challenges and to test the hypothesis that a shift in the neonatal leptin surge would result in sex-specific metabolic changes. METHODS/STUDY POPULATION: We studied pups from undernourished dams which were calorically restricted by 20% (CR20) from embryonic day 15 until postnatal day (PND) 21. We tested 216 offspring from 11 Fed dams and 13 undernourished dams (CR20), detecting a leptin surge in control fed progeny at PND11. At 3 months of age, offspring from 3 dams per maternal nutrient status were either exposed to a 45% high fat diet (HFD) or control diet (10% fat) for 16 weeks. Anterior pituitary hormones were analyzed in the pituitary and serum of neonates and adults. To determine the mechanism of the phenotype observed in male adult offspring on the HFD, single cell RNA sequencing was used to analyze the pituitary, fat and liver. RESULTS/ANTICIPATED RESULTS: Offspring of CR20 dams had an early leptin surge peaking at PND8 and GH levels at PND1 were higher in CR20 progeny. Weights of both male and female CR20 offspring were lower and body lengths were shorter than controls. As adults, Fed mice from both sexes had increased weight gain with HFD. However, although CR20 females gained weight on the HFD, male progeny from CR20 dams did not gain weight on the HFD and appeared protected from impact. We found sex-specific changes in pituitary Gh, Ghrhr, and Ghsr mRNA levels. Single cell RNA sequencing of pituitary, fat and liver of male offspring showed significant regulation of transcripts in fat of male offspring from Fed dams that was not found in CR20 males when compared to control fed mice. DISCUSSION/SIGNIFICANCE: Mild undernutrition causes a prematurely high leptin surge and sex-specific growth responses to a HFD, including resistance to a HFD in underfed males. Transcript analysis in fat of males resistant to HFD induced obesity may reveal mechanisms that provide protection against HFD induced weight gain.
