There are numerous examples of translational science innovations addressing challenges in the translational process, accelerating progress along the translational spectrum, and generating solutions relevant to a wide range of human health needs. Examining these successes through an education lens can identify core principles and effective practices that lead to successful translational outcomes. The National Center for Advancing Translational Sciences (NCATS) is identifying and teaching these core principles and practices to a broad audience via online courses in translational science which teach from case studies of NCATS-led or supported research initiatives. In this paper, we share our approach to the design of these courses and offer a detailed description of our initial course, which focused on a preclinical drug discovery and development project spanning academic and government settings. Course participants were from a variety of career stages and institutions. Participants rated the course high in overall value to them and in providing a unique window into the translational science process. We share our model for course development as well as initial findings from the course evaluation with the goal of continuing to stimulate development of novel education activities teaching foundational principles in translational science to a broad audience.

To facilitate and sustain community-engaged research (CEnR) conducted by academic-community partnerships (ACPs), a Clinical Translational Science Award (CTSA)-funded Community Engagement Core (CEC) and Community Partner Council (CPC) co-created two innovative microgrant programs. The Community Health Grant (CHG) and the Partnership Development Grant (PDG) programs are designed to specifically fund ACPs conducting pilot programs aimed at improving health outcomes. Collectively, these programs have engaged 94 community partner organizations while impacting over 55,000 individuals and leveraging $1.2 million to fund over $10 million through other grants and awards. A cross-sectional survey of 57 CHG awardees demonstrated high overall satisfaction with the programs and indicated that participation addressed barriers to CEnR, such as building trust in research and improving partnership and program sustainability. The goal of this paper is to (1) describe the rationale and development of the CHG and PDG programs; (2) their feasibility, impact, and sustainability; and (3) lessons learned and best practices. Institutions seeking to implement similar programs should focus on integrating community partners throughout the design and review processes and prioritizing projects that align with specific, measurable goals.

A decline in routine vaccinations, attributed to vaccine hesitancy, undermines preventative healthcare, impacting health and exacerbating vaccine disparities. University-public health partnerships can improve vaccination services. This study describes and evaluates a university-public health use case employing social determinants of health (SDoH)-based strategies to address vaccination disparities. Guided by the Translational Science Benefits Logic Model, the partnership offered no-cost preventative vaccines at community-based organization (CBO) sites, collected CBO clientele’s vaccination interest, hesitancy, and demographic data, and conducted descriptive analyses. One hundred seven vaccination events were held, administering 3,021 vaccines. This partnership enhanced health outcomes by addressing disparities through co-located vaccination and SDoH services.

OBJECTIVES/GOALS: As the number of older adults (≥65 years) with T1D grows, there are limited data to guide care. In a six-month trial, CGM reduced hypoglycemia in older adults, yet there are challenges for widespread uptake. Our objective is to characterize older adults experiences with using CGM and define suboptimal responses signaling a need for resources or support. METHODS/STUDY POPULATION: The study will engage key stakeholders (i.e., older adults with T1D, caregivers [recruited as patient-caregiver dyads], and providers [endocrinologists, geriatricians, diabetes educators]) for a Group Model Building (GMB). GMB is a participatory approach to system dynamics in which participants share perceptions and experiences with a problem and collaboratively explore the system structure that shapes those trends. A series of 8 GMB workshops will be held with 3-8 participants. The final study n will be determined by thematic saturation. Workshops comprise 1) a questionnaire, 2) a GMB session, and 3) a focus group discussion. GMB will follow a replicable process to generate a model of the complex web of causal determinants affecting CGM-related experiences, including optimal and suboptimal CGM responses. RESULTS/ANTICIPATED RESULTS: To date, the study has enrolled 33 participants, including 28 older adults living with T1D and 5 caregivers (mean age = 74 years, range 67-83 years). Twenty-four patient participants will be active CGM users and 4 will be CGM non-users. The study will report on patient data capture from the questionnaire and EMR, including demographics, experiences, familiarity, and confidence surrounding CGM use; diabetes duration; insulin pump use; history of severe hypoglycemia. Analysis of aggregated data will generate causal loop diagrams that integrate pertinent theoretical frameworks, lived experiences, and CGM outcomes. Maps will be used to identify a set of suboptimal CGM responses (i.e., key outcome trajectories) that signal a need for action, with a diagram of factors that interact to produce each response. DISCUSSION/SIGNIFICANCE: Delivering CGM to older adults with T1D demands new approaches. This study will yield critical evidence to tailor support and resources for effective CGM use in older adults. Findings may be translated into suite of pragmatic interventions to bolster CGM use and matched to individual patients expected to benefit using a precision medicine framework.

OBJECTIVES/SPECIFIC AIMS: To determine the association between clinical characteristics and platelet reactivity in Hispanic patients on clopidogrel therapy. METHODS/STUDY POPULATION: A cross-sectional pilot study was performed in 58 Puerto Rican patients diagnosed with any type of vascular disease and actively receiving a maintenance dose of clopidogrel for at least 7 days. The study population was divided into 2 groups: Group I with non-high on-treatment platelet reactivity (TPR); Group II with high TPR. To determine the platelet function, P2Y12 reaction units (PRU) were obtained by VerifyNow® P2Y12 assay (Accumetrics, USA). RESULTS/ANTICIPATED RESULTS: We studied a heterogeneous cohort of patients with coronary artery disease (57%), peripheral artery disease (30%), carotid artery stenosis (7%), cerebral artery aneurysm (3%), and stroke (3%) on clopidogrel therapy for secondary prevention of thromboembolic events. The mean TPR was 205±49 PRU (range: 61–304), with a prevalence of 28% patients with high TPR (PRU≥230). No significant clinical differences were found between the non-high TPR and high-TPR groups (p>0.05). However, multivariable logistic regression analysis showed that both diabetes mellitus (OR=7.5; CI: 1.01–51.9) and proton-pump inhibitors (OR=13.6; CI: 1.3–142.0) were independently correlated with high TPR (p<0.05) after adjusting for other clinical variables. DISCUSSION/SIGNIFICANCE OF IMPACT: These results provide new insight into the importance of clinical characteristics on platelet reactivity in this Caribbean population. Further studies are warranted to determine whether important clopidogrel pharmacogenes are related with platelet function in Hispanics, as well as the role of TPR in guiding antiplatelet therapy and predicting future adverse cardiovascular events in this population.

OBJECTIVES/GOALS: To ameliorate the leaky pipeline of physician-scientists, we must address the factors that cause medical trainees to disengage from research. Here we describe the development of standardized Physician-Scientist Training Program guidelines that may be implemented across disciplines to address these challenges. METHODS/STUDY POPULATION: Maintenance of a robust pool of physician-scientists is critical to meet the rapidly growing need for novel therapeutics. A variety of factors contribute to the decline of this pool. Key among these are a lengthy training period that segregates research from clinical training, thus impeding research progress and milestones that allow for a successful research career. Through engagement of residency program directors and Vice Chairs of Research, we have created a series of guidelines that promote residency research tracks and enable better integration of research and clinical training time. Guidelines have been piloted in the Departments of Pediatrics, Medicine and Surgery in the context of 2 new R38-supported programs. RESULTS/ANTICIPATED RESULTS: Our physician-Scientist Training Program (PSTP) guidelines were developed by our central Office of Physician-Scientist Development (OPSD) after a successful pilot of an integrated research residency program in the Department of Pediatrics [Duke Pediatric Research Scholars (DPRS); Hurst, et al, 2019], which has included 36 resident and fellow scholars over 3 years. To date, eight clinical departments have adopted our PSTP guidelines as part of their R38-supported or pending programs. The OPSD has recently created a tracking database for scholar metrics, which will further promote PSTP development by enabling centralized reporting on scholar success to individual programs. DISCUSSION/SIGNIFICANCE OF IMPACT: PSTP guidelines enable effective implementation of new programs by sharing best practices and lessons learned, standardizing expectations, and defining metrics of success. By promoting proven strategies for integrated clinical and research training, PSTP guidelines may aid in retaining trainees pursuing research careers.

ABSTRACT IMPACT: This work will help assess the effectiveness of the mentored career development programs. OBJECTIVES/GOALS: There is increased attention on assessing the impact of the CTSA in building a research workforce through mentored career development programs. We propose using data visualization to assess and communicate the impact of the programs on the scholars career development. METHODS/STUDY POPULATION: Evaluators from two CTSAs collaborated to visualize the KL2 data such as demographics, scholarly productivity (publications, grants, intellectual property), and time to promotion that is already tracked through REDCap at their institutions. Excel, Tableau, and Microsoft PowerBi were then used to generate trends in scholarly productivity over time. The goal was to compare how different tools can be used to visualize bibliometric data, based on what is available at the respective institutions. RESULTS/ANTICIPATED RESULTS: Longitudinal visual summary reports were produced for the entire program as well individual scholar progress. These reports can be used to identify trends such as how long after program completion do participants achieve their next milestone, what type of milestones are achieved, when in their career is their scholarly productivity the highest, etc. Answers to these questions could tell a story of the effectiveness of a mentored development program in the participants’ career. It can also highlight gaps and areas of opportunities that the program must address, either by adapting their curriculum or clarifying their intended outcomes. DISCUSSION/SIGNIFICANCE OF FINDINGS: Data visualization provides better understanding of the impact of the training programs on the scholars career development. Such insights are otherwise missing when evaluations are only focused on the percentage of scholars who were still engaged in research after completion of the program.

OBJECTIVES/SPECIFIC AIMS: Improving human papillomavirus (HPV) vaccination rates ultimately decreases the morbidity and mortality of HPV-associated diseases. A school-based program was piloted in the Rio Grande City Consolidated Independent School District (RGCCISD) to increase HPV vaccination. METHODS/STUDY POPULATION: We assessed baseline HPV vaccination; surveyed 622 parents of eligible children aged ≥9 years; and piloted and developed a school-based HPV education and vaccination program in 1 middle school in 2017 and 4 additional middle schools in 2018. The parent survey included (1) demographic information, (2) an assessment of parental knowledge about the HPV vaccine, and (3) information about their children and HPV vaccine experience. Results of the parent survey and pilot program are in progress. RESULTS/ANTICIPATED RESULTS: As of 9/1/2016, 20.4% of the 7527 RGCCISD eligible students (≥9 years) had completed the HPV vaccine. Baseline completion rates were higher for RGCCISD students aged 12–14 years compared with students aged 9–11 and ≥15 years (28.4% vs. 16.5%). Baseline completion rates for RGCCISD adolescents were substantially lower than those reported in NIS-Teen and for Texas (42% females and 28% males for NIS-Teen vs. 41% and 24% for the state of Texas). DISCUSSION/SIGNIFICANCE OF IMPACT: Initial results show that engagement with key stakeholders is important and schools are a great venue for delivering and increasing HPV vaccination.

OBJECTIVES/GOALS: Assess the diagnostic yield and test utilization of WES in patients having complex traits. We aim to evaluate the use of the first genetic approach for the identification of primary variants that contribute to neurogenetic disease etiology and influence onset and progression in Puerto Ricans. METHODS/STUDY POPULATION: Prospective cohort of 45 Puerto Rican probands (19 months - 36 years old) with complex neurogenetic traits that underwent WES (2019 - 2021). WES was performed, including copy number variant analysis and mitochondrial genome sequencing. We evaluated several factors possibly influencing the rate of WES diagnosis including early age, consanguinity, and family history of neurogenetic diseases. In addition, we only evaluated probands rather than dyads/trios and the clinical phenotypes. Descriptive analysis was performed, including a catalog of all variants reported. Multivariate analysis was performed to estimate the statistical association between variants and phenotypes reported and adjusting for potential confounders (age, sex, family history, income, health insurance and zip code). RESULTS/ANTICIPATED RESULTS: Auspiciously, positive pathogenic findings altered the clinical management in 29% of the probands in this study. A likely genetic diagnosis was achieved in 53% of the probands including pathogenic, likely pathogenic and variants of uncertain significance. Intronic variants, copy number variants detection and mitochondrial genome was included in WES methodology. Despite these facts, a 47% of the reported WES were negative, which deserve re-analysis potentially genotype based. Multivariate analysis is expected to adjust for potential confounders to establish a genotype-phenotype correlations in neurogenetic complex traits in this Puerto Rican admixed population. DISCUSSION/SIGNIFICANCE: Clinical WES offers an alternative approach for identification of variants in patients with complex traits. WES is also applicable in genetically heterogeneous individuals when specific genetic tests are not available or unsuccessful. Variants reported contribute to understand complex neurogenetic disease in underrepresented Puerto Ricans.

OBJECTIVES/SPECIFIC AIMS: The DIAMOND project encourages study team workforce development through the creation of a digital learning space that brings together resources from across the CTSA consortium. This allows for widespread access to and dissemination of training and assessment materials. DIAMOND also includes access to an ePortfolio that encourages CRPs to define career goals and document professional skills and training. METHODS/STUDY POPULATION: Four CTSA institutions (the University of Michigan, the Ohio State University, University of Rochester, and Tufts CTSI) collaborated to develop and implement the DIAMOND portal. The platform is structured around eight competency domains, making it easy for users to search for research training and assessment materials. Contributors can upload links to (and meta-data about) training and assessment materials from their institutions, allowing resources to be widely disseminated through the DIAMOND platform. Detailed information about materials included in DIAMOND is collected through an easy to use submission form. DIAMOND also includes an ePortfolio designed for CRPs. This encourages workforce development by providing a tool for self-assessment of clinical research skills, allowing users to showcase evidence of experience, training and education, and fosters professional connections. RESULTS/ANTICIPATED RESULTS: To date, more than 100 items have been posted to DIAMOND from nine contributors. In the first 30 days there were 229 active users with more than 500 page views from across the U.S. as well as China and India. Training materials were viewed most often from four competency domains: 1) Scientific Concepts & Research Design, 2) Clinical Study Operations, 3) Ethical & Participant Safety, and 4) Leadership & Professionalism. Additionally, over 100 CRPs have created a DIAMOND ePortfolio account, using the platform to document skills, connect with each other, and search for internships and job opportunities. DISCUSSION/SIGNIFICANCE OF IMPACT: Lessons learned during development of the DIAMOND digital platform include defining relevant information to collect for the best user experience; selection of a standardized, user-friendly digital platform; and integration of the digital network and ePortfolio. Combined, the DIAMOND portal and ePortfolio provide a professional development platform for clinical research professionals to contribute, access, and benefit from training and assessment opportunities relevant to workforce development and their individual career development needs.

Objectives/Goals: This project aims to inform and develop a clinician-centered educational tool evidence-based and stakeholder-informed that fosters healthcare professionals’ (HCPs) adaptive expertise (AE) in cannabinoid-based therapies (CBT) for chronic pain management (CPM), addressing existing knowledge gaps, improving patient care and clinical decision-making. Methods/Study Population: To achieve this, the project will use a mixed-methods approach divided into three phases to evaluate existing educational resources, identify gaps, and inform the design of a curriculum to transform clinician education in CBT for CPM. It includes stakeholder mapping to engage and consult key experts for real-world insights and an environmental scan to assess and compare current educational resources qualitatively. A rigorous curriculum will be informed to be designed through an adaptive expertise and reflective practice framework, emphasizing case and problem-based learning, clinical simulations, and other pedagogical techniques. The educational tool will be pilot-tested with clinicians, measuring its impact on knowledge and decision-making flexibility through pre- and post-assessments, ensuring it fosters AE on CBT. Results/Anticipated Results: The project is expected to identify key gaps in existing educational resources, particularly AE in HCPs specializing in CPM. Through pilot testing, we anticipate improved knowledge of CBT among clinicians and enhanced ability to apply this knowledge flexibly in clinical practice. We also expect to establish core curriculum components that better support routine and adaptive expertise in chronic pain management. The pilot evaluations will guide further curriculum refinement and inform broader educational implementation. Discussion/Significance of Impact: This project addresses critical gaps in CbT education by informing the development of a curriculum that enhances clinicians’ ability to manage chronic pain with cannabinoid-based therapies. The resulting educational tool could significantly impact clinical practice, empowering patients, and HCPs to make informed decisions and improve patient outcomes.

OBJECTIVES/SPECIFIC AIMS: We propose to adapt a curriculum for group well-child care in order to (1) improve the experience of care for Latino immigrant families, (2) better address maternal psychosocial concerns impacting parenting and (3) teach parenting practices that promote healthy behaviors, and (4) improve LEP parent health literacy, engagement, and self-management in care. METHODS/STUDY POPULATION: This study is composed of a series of focus groups with 4 target populations: (1) The Johns Hopkins Bayview Children’s Medical Practice Latino Family Advisory Board (LFAB) (multiple meetings). The LFAB has been in existence since 2011, and has experience in iteratively adapting educational materials, both written and video, and in providing input on social work services and healthcare utilization. We will meet with the LFAB over the course of up to 8 meetings. During these meetings, the following themes will be discussed: (A) The concept of Group Well Child Care will be discussed and LFAB members will be asked about potential benefits and drawbacks of this format. (B) LFAB members will also be asked about group discussion topics that should be prioritized. Study staff will both bring up a list of topics (feeding, sleep, development, behavior, parent stress) and ask for input on additional items that should be discussed. (C) Core components of the mothers and babies course, a group perinatal depression intervention originally developed with Latina mothers, will be presented and discussed with board members, who will be asked to prioritize the components for salience and perceived helpfulness as well as inclusion in the Group Visit Curriculum. Potential benefits and drawbacks of including components of this program will also be asked of LFAB members. Members will not be asked about their depressive symptoms. (2) Pediatric providers (including social workers, MDs, NPs, and RNs) (1 focus group) who agree to participate will also be asked about perceived benefits and drawbacks of the group well-child care model, topics that should be prioritized in the educational components, and the benefits and drawbacks of including components of a perinatal depression prevention program in the group well child visit curriculum. (3) Obstetric group visit providers—Obstetric providers of group prenatal care to LEP Latinas at JHBMC will be asked about the benefits and drawbacks of group prenatal care with their patient population, as well as topics perceived to be of relevance to the patient population based on their experience with group prenatal care and discussions that emerged during the course of the facilitated groups. (4) Obstetric group visit patients (3 focus groups) LEP Latina patients who have participated in at least 3 group prenatal visits will be invited to participate in focus groups exploring the aforementioned topics. The experience of discussing psychosocial issues, including maternal depressive symptoms, in the group visit format will be emphasized. RESULTS/ANTICIPATED RESULTS: One focus group with obstetric providers and has thus far been conducted. Obstetric providers reported that patients were very open in discussing prior experiences with postpartum depression, and discussed feelings of loneliness with their peers in this setting. Anxiety was also frequently discussed. History of domestic violence was discussed more frequently than current domestic violence. DISCUSSION/SIGNIFICANCE OF IMPACT: Group visits may represent an opportunity to more effectively address psychosocial concerns in Latinas. Work needs to be done to understand which topics are most effectively and appropriately addressed in the group Versus individual format.

OBJECTIVES/SPECIFIC AIMS: To establish an in vitro quantitative method for the evaluation of polymeric film disintegration that can be applied to predict in vivo behavior. METHODS/STUDY POPULATION: Two clinically advanced vaginal microbicide film products containing tenofovir and dapivirine were used as model films throughout this work. Films were made using the solvent cast manufacturing method in which polymers, excipients, plasticizer, and APIs were either dissolved or dispersed in water, mixed, and cast on a heated substrate. The novel, quantitative method was developed using a TA.XT Plus Texture Analyzer® (Texture Technologies) in combination with a TA-108S5 fixture and the TA-8A: 1/8″ diameter rounded end ball probe. Exponent® was used as the data analysis software. In this method, the film was placed and secured in the fixture, the probe applied a constant force to the film product, and a biologically relevant amount of fluid was applied to the film. The probe was able to penetrate the film upon disintegration resulting in an applied force of zero at that point. A curve of force Versus time was plotted, and disintegration time was defined as the time between fluid addition until the probe force reached zero. Test parameters were optimized in order to reduce error. Visual observation of film disintegration was conducted in the in vivo macaque model using films that included a water-soluble blue dye for film visualization. Colpophotography was also used to confirm film disintegration. In vitro results were compared with in vivo findings. RESULTS/ANTICIPATED RESULTS: The Texture Analyzer disintegration method developed provided quantitative disintegration times and did not rely on user defined endpoints which is common in many visual disintegration tests. The disintegration method was able to distinguish differences between the 2 clinical film products and produced reproducible disintegration times for the tenofovir and dapivirine films. The tenofovir film had a shorter disintegration time (41.28±2.85 s) compared with that of the dapivirine film (88.3 6±9.82 s). This method was also able to distinguish changes made to these 2 clinical film products in terms of volume and formulation alterations. In vitro and in vivo disintegration times differed by orders of magnitude, with in vitro time being measured in seconds and in vivo time being measured in days, for a variety of factors, mainly the application of constant force to the film product. Regardless of these differences, the rank order of film disintegration remained constant for in vitro and in vivo disintegration and an In Vitro In Vivo Correlation (IVIVC) trend could be seen. DISCUSSION/SIGNIFICANCE OF IMPACT: Standardization of preclinical in vitro assessments which minimize user bias are crucial to the field of pharmaceutical film development. As this field continues to develop and more products advance for pharmaceutical application, this method has the potential to become a standard assessment of film functionality. This study represents a first step in the process of developing an IVIVC. More films will need to be tested using both in vitro and visual methods in order to establish and accurate factor to predict in vivo behavior.

OBJECTIVES/GOALS: Methods for recruitment and retention of participants in research have been extensively discussed, but procedures to end studies in a way that is respectful to participants and keeps them engaged are seldom described. We relate the procedures to close a study focused on genomic DNA damage and DNA repair capacity in a longitudinal population sample. METHODS/STUDY POPULATION: Data collection, which included the provision of 30 ml blood sample along with a health status survey and anthropometric measurements, was discontinued earlier than anticipated during the fourth of a five-year Community Engaged Research (CEnR) study focused on residents of historically marginalized, low wealth communities. In collaboration with the project’s Community Advisory Board, we devised a strategy to inform study participants of the study closure, which included: 1) attempts at one-on-one contact via phone, 2) provision of a study closure packet, 3) periodic mailing of study updates through study year five, 4) sustained interaction with participants through invitations to participate in additional research projects. RESULTS/ANTICIPATED RESULTS: Among 149 participants (65% female, 99% of African American descent), 106 (71%) have been reached by phone. The communication included: 1) expressions of gratitude for their participation; 2) explanation of study findings to date; and 3) assurance that data analysis continued. Among those reached, 96% agreed to ongoing communication and 97% agreed to be contacted about future studies. We continue procedures to reach the remaining 43 participants. Over the study closure period, two qualitative studies offered opportunities for participants to join in focus groups (FG). The first one queried perceptions of community-based research. The response rate was 66% among 65 persons invited. The second study, focused on COVID-19 knowledge and invited 39 individuals with 24 scheduled to participate (62% response rate). DISCUSSION/SIGNIFICANCE: Translational research views the participant as an active partner. Study closure offers an opportunity to foster a long-lasting participant-research institution partnership, while also promoting participants’ broad engagement and familiarity with research. Respectful research closure is an important step in CEnR.

OBJECTIVES/GOALS: Investigate the perspectives of people experiencing homelessness (PEH) on clinical trials to uncover knowledge gaps and attitudes. This study aims to offer insights for clinical researchers to enhance engagement with this marginalized group, ushering in a more inclusive clinical trial process. METHODS/STUDY POPULATION: A 14-question survey was developed in collaboration with the Street Medicine Team at the University of Southern California and other stakeholders of PEH research. Initial questions assess knowledge of clinical trials, followed by questions gauging sentiments on clinical trial participation, and final questions on the significance, benefits, and risks of clinical trials. Upon approval by the local Institutional Review Board, the survey will be administered in an interview format. Study participants will be from locations within the area of operations of the USC Street Medicine team–in and around Hollywood, South Los Angeles, and/or the Los Angeles Council District 1. RESULTS/ANTICIPATED RESULTS: We anticipate that the results of this study will offer valuable insights into the perspectives of PEH regarding clinical trials. Results will also provide varying levels of knowledge and understanding among PEH about clinical trials, along with their past experiences in clinical trial participation, and willingness for future involvement in such trials. Further, the results will reveal whether respondents feel they are being properly represented in clinical research projects that could impact themselves and their community. This project can also enhance our understanding of the expectations and concerns of PEH regarding their potential participation in clinical trials. DISCUSSION/SIGNIFICANCE: The outcomes of this research project have the potential to lay the groundwork for enhancing the involvement of PEH in translational science research, encompassing aspects from study design to participation. This improvement could benefit not only participants but also various stakeholders involved.

OBJECTIVES/GOALS: Sex differences in aortic stenosis (AS) are vastly underestimated, contribute to disparities in treatment and worse outcomes for women including disproportionately higher mortality rates. This study aims to investigate sex differences in extent of cardiac damage (CD) from pressure overload in AS that may help account for the observed disparities. METHODS/STUDY POPULATION: CD in AS refers to a series of pathologic changes in the myocardium that occur due to chronic pressure overload imposed on the left ventricle by a progressively stenotic aortic valve (AV). These changes are associated with poor outcomes and lower survival in patients with AS. To acquire a deeper understanding of the factors and mechanisms affecting differences in the long-term survival and management of patients with AS, we are proposing to assess baseline stage of CD on echocardiography, and changes in transvalvular hemodynamics and CD stage (Δ CD) over time, in patients with moderate and severe AS at one of 2 large tertiary-care hospitals in MA. We also plan to assess time to and performance of aortic valve replacement (AVR), stratified by hemodynamic severity of stenosis and CD stage, and their interaction with sex. RESULTS/ANTICIPATED RESULTS: We hypothesize that women will have a higher stage of CD on their initial echocardiogram (TTE), demonstrating moderate or greater severity of AS, than men with the same hemodynamic severity of valvular stenosis. We additionally hypothesize that those with more advanced cardiac damage stage will likely have masking of transvalvular progression on echocardiogram. Finally, we anticipate that women will have AVR performed less frequently than men and will have minimal improvement in their Kansas City Cardiomyopathy Questionnaire (KCCQ) scores post-AVR indicative of more heart failure symptoms and a lower quality of life. DISCUSSION/SIGNIFICANCE: This study will seek to better understand sex-based differences in extent of cardiac damage to pressure overload in aortic stenosis (AS) to minimize treatment and outcome disparities for women and allow for more individualized and patient-centered care.

OBJECTIVES/GOALS: Community-based participatory research is a “gold standard” methodology, yet many researchers lack the experience or resources to implement this approach. To make engagement more accessible, we developed and implemented a 3-part training series highlighting engagement as a spectrum with many options to meaningfully engage partners. METHODS/STUDY POPULATION: Staff at UNC-Chapel Hill’s CTSA and Cancer Center collaborated with patient and community partners to co-develop training content, structure, and delivery. Sessions were free and open to the public and covered key components of research engagement and its benefits, debunked common myths and misconceptions about engagement, outlined specific methods along the spectrum of engagement (from low to high touch), and described nuances of building and maintaining partnerships. Partners determined how to best incorporate their perspectives, developed content (including videos, audio clips, and quotes), and co-presented with UNC staff. Evaluations were collected after each session and feedback was incorporated into future iterations. RESULTS/ANTICIPATED RESULTS: 194 individuals from over 20 institutions have participated in the training. Of all survey respondents to date (n=74), 93% were very or extremely satisfied, 77% felt the training was very or extremely relevant to their work, and 76% were very or extremely likely to use information learned in the next year. Most helpful parts of the training were differentiating research engagement from participation; explaining engagement as a spectrum with varied methodologies; providing tools and resources to implement different approaches; and hearing directly from community co-presenters about their experiences engaging in research. Based on feedback, we created a workshop for researchers to develop engagement plans and an additional training for partners to build capacity and knowledge about engaging in research. DISCUSSION/SIGNIFICANCE: Engaging partners who are impacted by research can be instrumental to the success of a study. This training can help researchers identify engagement approaches that align with their goals, experience, and resources, as well as the interests and capacity of potential partners, and can serve as a model for those interested in training co-development.

ABSTRACT IMPACT: This work highlighs the significant burden of Trauma in Nigeria and will help inform policy decisions on improving Nigeri’s current Trauma care system OBJECTIVES/GOALS: To evaluate trauma care delivery at the pre-hospital, hospital and health systems level in Nigeria in order to identify the burden of trauma, gaps in the delivery of trauma care, and interventions, implemented or recommended, to improve upon the limitations to trauma care delivery. METHODS/STUDY POPULATION: A two-concept search - one being trauma and the other being Nigeria - of the Pubmed (Medline) and Embase databases, in addition to Global Index Medicus and grey literature was performed between September 2018 and September 2019. The search yielded 3,970 articles that underwent title screening and 331 articles that underwent abstract screening. 101 articles were identified for full text screening and the majority were extracted for inclusion into the review. The extracted literature was grouped into 4 categories - articles outlining the burden of trauma in Nigeria, and articles outlining the delivery of trauma care at the pre-hospital, hospital and health systems level. RESULTS/ANTICIPATED RESULTS: Results were classified as an identified challenge or an intervention, recommended or implemented, to address Nigeria’s trauma care system. There was a highlighted need for pre-hospital infrastructure, training of frontline providers, continued competency assessments of frontline providers, in-hospital diagnostic resources, and trauma care surveillance systems to guide health policy. DISCUSSION/SIGNIFICANCE OF FINDINGS: There is a significant burden of trauma in Nigeria. Coordinated interventions and policies at the pre-hospital level, the hospital level, as well as the health systems level are needed in order to address the gaps in Nigeria’s current trauma care system.

OBJECTIVES/SPECIFIC AIMS: This poster will present preliminary results from a study examining whether person-centered care planning—a new innovation in community mental health care—responds to the culture of, and helps reduce health disparities among, Latinx and Asian populations. METHODS/STUDY POPULATION: The study was funded by an NIMH/NIH Administrative Supplement for Minority Health and Mental Health Disparities Research and approved by the Institutional Review Board of the authors’ university. Participants included 26 mental health clients and 12 mental health providers of diverse backgrounds. The study employed empirical qualitative methods to explore client understandings of mental health, client experiences of culture and discrimination, and the process of care engagement and care planning from both client and provider perspectives. The analysis team itself included people of Latinx and Asian background, as well as a person with lived experience of mental health recovery. RESULTS/ANTICIPATED RESULTS: We anticipate that the results will show ways in which person-centered care successfully incorporates clients’ goals, but that there will also be evidence of ways in which the clinical encounter struggles to incorporate more social, collective, and cultural values and approaches. DISCUSSION/SIGNIFICANCE OF IMPACT: The poster will present up-to-date findings on this project, which speaks to pressing issues of health equity and community engagement for 2 of the fastest growing populations in the country.
