OBJECTIVES/SPECIFIC AIMS: There is no consensus on what constitutes translational research. To effectively support translation of research into practical settings, universities must determine who is involved, in which disciplines, and what results. In addition, it is unclear whether these researchers would see “translational research” as describing their work. METHODS/STUDY POPULATION: A survey assessing perceptions, successes, and barriers to the application of research was distributed to faculty, fellows, and graduate students within the University of Michigan. This survey included a question on the definition of translational research. RESULTS/ANTICIPATED RESULTS: Investigators of every rank and school participated (n=865), and all schools reported forms of applied research. Over 70% of participants said it was important to use research results beyond academia, and those responses represented diverse successes ranging from product development to artistic endeavors. Common barriers to such as lack of time and funding were also widely experienced. The definitions of translational research were divided between strictly health-oriented or broadly focused application. However, both definitions and familiarity with the term differed by field. DISCUSSION/SIGNIFICANCE OF IMPACT: Translation of research is widespread throughout the university, and many would define translational research to include their research discipline. Strategic university policies could benefit society by enhancing translation and application across many disciplines.

OBJECTIVES/GOALS: Congenital anomalies (CA) are common, but the cause is often unknown. The interplay between known environmental teratogens, such as medication use in pregnancy, and genetic predisposition impacts CA risk, but such interactions are poorly understood. We test the hypothesis that pharmacogenomic (PGx) variation impacts CA risk. METHODS/STUDY POPULATION: We performed a drug absorption, distribution, metabolism, and excretion (ADME) gene-wide association study (GWAS), which tests for a possible association between ADME gene single nucleotide polymorphisms and individuals with CAs. This analysis was performed in BioVU and utilized billing codes to identify 5,845 cases, individuals with at least one CA, and 50,059 controls of genetically European ancestry. Using Plink software we analyzed 5,398 SNPs in 292 ADME genes across cases and controls. Results from this analysis drove us to further investigate the association between CA risk and SLC22A1-3. Next, we performed PrediXcan analyses to estimate the association between genetically predicted gene expression (GPGE) of SLC22A1-3 genes across all available tissues in the GTEx resource and CA risk. RESULTS/ANTICIPATED RESULTS: The ADME GWAS identified multiple variants on chromosome 6 in the region of SCL22A1-3 that were associated with the risk for CAs. The most significant variants were rs2048327, rs2292334, rs3088442, rs1810126, rs376563, and rs7758229, p DISCUSSION/SIGNIFICANCE: The combination of the known crucial pharmacological roles of OCT1-3 and the results of our ADME GWAS / PrediXcan analyses demonstrates that PGx burden, specifically variation in the SLC22A1-3 genes, influences the risk of developing CAs. This new understanding has the potential to personalize care for pregnant individuals to reduce the risk of CAs.

OBJECTIVES/GOALS: Age-specific N-glycosylation occurs on follicle- stimulating hormone (FSH) in pituitaries of post-menopausal women and results in a higher ratio of fully glycosylated to hypoglycosylated FSH. Our goal is to identify in vivo the N-glycosylation pathway enzymes and the regulatory mechanisms in gonadotropes of young and old female mice. METHODS/STUDY POPULATION: Pituitaries were isolated from female mice (at 4m and 8m; n=5 per group) carrying an Fshb-Cre transgene on a Rosa mT/mG genetic background and the GFP-tagged gonadotropes were purified by FACS. RNA-Seq analysis, and subsequent qPCR assays were performed on GFP+ cells from pituitaries of female mice at 4m (reproductively young), 8m (reproductively mid age) and ≥ 12m (reproductively old) of age. To identify the role of progesterone signaling in age-dependent N-glycosylation in gonadotropes, a gonadotrope-specific knockout of Pgr was achieved. Gonadotropes from these mutant mice at 4-, 8-, and ≥12 months of age (n=5 per group) were isolated for qPCR analysis of N-glycosylation enzyme gene expression. Predicted progesterone receptor (PR) promoter binding sequences was performed using JASPAR. RESULTS/ANTICIPATED RESULTS: RNA-seq identified 28 differentially expressed N-glycosylation enzyme-encoding mRNAs in gonadotropes of female mice at 4- and 8-months. Three genes showed significant differences between ages (Man2a1, Man1c1, and B4galt5.), and further qPCR analyses revealed six out of eight genes analyzed showed age-dependent expression, including Man2a1, Man1c1, and B4galt5. The promoters of all N-glycosylation enzyme genes showed strong predicted binding sequences for PR. Further qPCR analysis showed age-and genotype-dependent differences in N-glycosylation enzyme expression in Pgr cKO females, with the most striking differences observed at 13 months, where B4galt5, Man1a2, Mgat5, and Man2a1 were downregulated in Pgr cKO gonadotropes compared to controls. DISCUSSION/SIGNIFICANCE: We identified changes in the N-glycosylation machinery in female mouse gonadotropes and confirmed the age- and Pr-dependent regulation of the corresponding mRNAs. Our results provide insights into the mechanisms at the level of the pituitary by which old age-specific FSH glycoform regulates osteoporosis and weight gain in post-menopausal women.

OBJECTIVES/SPECIFIC AIMS: The population of cancer survivors is rapidly growing in the United States. Long term and late effects of cancer, combined with ongoing management of other chronic conditions, make cancer survivors particularly vulnerable to polypharmacy and its adverse effects. We examined patterns of prescription medication use and polypharmacy in a population-based sample of cancer survivors. METHODS/STUDY POPULATION: Using data from the Medical Expenditure Panel Survey (MEPS), we matched cancer survivors (n=5216) to noncancer controls (n=19,588) by age, sex, and survey year. We defined polypharmacy as using 5 or more unique medications. We also estimated proportion of respondents prescribed specific medications within therapeutic classes and total prescription expenditures. RESULTS/ANTICIPATED RESULTS: A higher proportion of cancer survivors were prescribed 5 or more unique medications (64.0%, 95% CI 62.3%–65.8%) compared with noncancer controls (51.5%, 95% CI 50.4%–52.6%), including drugs with abuse potential. Across all therapeutic classes, a higher proportion of newly (≤1 year since diagnosis) and previously (>1 years since diagnosis) diagnosed survivors were prescribed medications compared to controls, with large differences in central nervous system agents (65.8% vs. 57.4% vs. 46.2%), psychotherapeutic agents (25.4% vs. 26.8% vs. 18.3%), and gastrointestinal agents (31.9% vs. 29.6% vs. 22.0%). Specifically, nearly 10% of cancer survivors were prescribed benzodiazepines and/or opioids compared to about 5% of controls. Survivors had more than double prescription expenditures (median $1633 vs. $784 among noncancer controls). Findings persisted similarly across categories of age and comorbidity. DISCUSSION/SIGNIFICANCE OF IMPACT: Cancer survivors were frequently prescribed a higher number of unique medications and inappropriate medications or drugs with abuse potential, increasing risk of adverse drug events, financial toxicity, poor adherence, and drug-drug interactions. Adolescent and young adult survivors appear at increased risk of polypharmacy.

OBJECTIVES/SPECIFIC AIMS: The National HIV/AIDS strategy aims to increase retention in care (RIC) to reduce HIV transmission and mortality. Previous studies have evaluated clinic-level interventions such as appointment reminders and peer navigation. However, few studies have investigated the association between multiple clinic-level factors and RIC among PLWH across the United States. We conducted a multi-site cohort study to identify clinic-level factors associated with RIC in the United States from 2010-2016. METHODS/STUDY POPULATION: We included PLWH with at least one HIV primary care visit from 2010-2016 at seven sites of the Center for AIDS Research (CFAR) Network of Integrated Clinical Systems (CNICS). Individual-level data collected as part of routine clinical care were abstracted from the electronic health record. Clinic-level data were gathered through a survey and included questions on site characteristics (i.e. clinic volume) as well as services available at the site during each year of the study: peer navigation, RIC posters/brochures, laboratory test timing, flexible scheduling, appointment reminder types, and stigma support services defined as intensive HIV education and advocacy regarding support to address stigma at outreach visits. RIC was defined as ≥2 encounters per year, ≥90 days apart, observed until death, administrative censoring (December 31, 2016), or loss to follow-up (no visit for >12 months with no future visits). Poisson panel regression with robust error variance, clustering by site and adjusting for calendar year, age (modeled with a cubic spline), sex, race/ethnicity, and HIV transmission risk factor, was used to estimate incident rate ratios (IRR) with 95% confidence intervals (CI) for RIC. Clustering by site has been shown to absorb for clustering that could occur at the individual level as well. RESULTS/ANTICIPATED RESULTS: Among 21,046 patients contributing 103,348 person-years, 67% of person-years were RIC. Text appointment reminders (IRR = 1.13; 95% CI: 1.03-1.24) and stigma support services (IRR=1.11; 95% CI:1.04-1.19) were significantly associated with RIC. RIC disparities in individual-level patient characteristics were observed even after accounting for clinic-level characteristics. Older patients were more likely to be RIC demonstrated through year comparisons due to the use of a spline; for age 50 years (IRR = 1.07, 95% CI: 1.06-1.08) and 60 years (IRR = 1.15, 95% CI: 1.13-1.17) compared to 45 years. Female PLWH were more likely to be RIC compared to males (IRR = 1.03, 95% CI: 1.02-1.05) and Hispanic PLWH were more likely to be RIC compared to white, non-Hispanic PLWH (IRR = 1.09, 95% CI: 1.05-1.13). Although commonly found to be associated with worse RIC, Black race and injection drug use were not associated with RIC in this population. DISCUSSION/SIGNIFICANCE OF IMPACT: In this multi-site US cohort study from 2010-2016, availability of text appointment reminders and stigma support services at a clinic were associated with approximately 10% higher probability of RIC than at clinics without those services. RIC disparities persisted with respect to individual-level characteristics of age, sex, and race/ethnicity even after accounting for these clinic-level factors. Prospective studies examining the impact of these clinic-level factors and individual-level uptake of these services on RIC are needed.

ABSTRACT IMPACT: This research suggests that African American and Latinx smokers who bear a disproportionate burden of tobacco-related harms are able to switch to e-cigarettes that present reduced harm to the user due to their similar reinforcement profile to cigarettes. OBJECTIVES/GOALS: Complete switching from combustible to electronic cigarettes (ECs) reduces harm to the user. For ECs to be a viable substitute, they need to be rewarding enough for regular use, indicated by factors such as craving and dependence (reinforcement value). Little is known about short-term changes in reinforcement value across trajectories of EC use. METHODS/STUDY POPULATION: Participants were randomized 2:1 to switch to a nicotine salt pod system EC or continue smoking (assessment-only control) in a 6-week trial. 114 African American (n=60) and Latinx (n=54) smokers were randomized to receive ECs and are included in the current investigation. At week 6, participants were classified by use trajectory: exclusive smokers (n=16), exclusive EC users (n=32), or dual users (n=66). Participants reported on their EC, cigarette, and total nicotine dependence (cigarette + EC dependence), cigarette and EC use, and nicotine craving and withdrawal at baseline and week 6. Cotinine and exhaled carbon monoxide were assessed at baseline and week 6. RESULTS/ANTICIPATED RESULTS: Participants who completely switched from smoking to ECs (exclusive EC users) and those that partially switched (dual users), maintained cotinine levels (ps>.05) and showed reductions in cigarette dependence and withdrawal (ps<.01). However, exclusive EC users showed no significant changes in total nicotine dependence from baseline to week 6 (p=.123), while dual users showed increased total nicotine dependence (p<.001). Dual users displayed similar levels of EC dependence as exclusive EC users but a lesser reduction in cigarette dependence. Exclusive EC users and dual users showed reductions in craving and withdrawal from baseline to week 6. DISCUSSION/SIGNIFICANCE OF FINDINGS: This study is among the first to prospectively examine changes in dependence, craving, and withdrawal among an understudied sample of smokers making a switch attempt. Smokers who completely switch to ECs maintain nicotine levels and dependence, suggesting that they have a similar reinforcement profile to cigarettes and facilitate switching.

OBJECTIVES/GOALS: Women within the ages of 65-75 have a lower incidence of heart failure than men.However,after the age of 75, the incidence of HF in womentriples,matchingthat of men.(Lloyd-Jones etal., 2002)Overall, women with heart failure live longer at the expense of presenting moresevere symptoms and poorer perceived quality of life.Generally, women with heart failurereceive suboptimal treatment throughout their lifetime. In fact, women are more likely todevelop heart failure after myocardial infarction. This trend is, in part, because physicians areless strict when treating them.(Chou et al., 2007)Studies in heart failure by ethnicity have shown that, despite equal access to healthcare, Hispanic women have higher rates of readmission than Non-Hispanic-white (NHW) women. (Durstenfeld, Ogedegbe, Katz, Park, &Blecker, 2016)One study in Boston demonstrated that Puerto Rican Women have higher rates of diabetes, obesity, and chronic kidney disease compared to blacks and NHW women.(Todorova, Tejada, & Castaneda-Sceppa, 2014)These are cardiovascular risk factors that warrant further study in Puerto Rican women living on the island, but data are lacking. Objective: The purpose of this study is to evaluate the gender disparities in presentation, management, and outcomes in Puerto Rican Hispanic hospitalized for heart failure METHODS/STUDY POPULATION: To this end, we will perform a secondary analysis of data from the PR CardiovascularSurveillance Study (PRCSS). We will extract personal data from 4,461 medical records of patients admitted with heart failure (ICD-9 Codes 428) at 21 hospitals in Puerto Rico, during theyears2007, 2009 and 2011. For statistical methods, we will implement chi-square and t-tests at a significance level of 0.05. RESULTS/ANTICIPATED RESULTS: We expect to find that women will have: fewer interventions, less optimized heart failure medication, higher BNP, older age of diagnosis, but paradoxically better outcome than male counterparts of the same age. DISCUSSION/SIGNIFICANCE OF IMPACT: With this study, we would like to raise awareness about gender-specific health disparities Puerto Rican Hispanic women with heart failure experience while hospitalized.

The National Institutes of Health (NIH) diversity supplements represent an opportunity to enhance diversity in the biomedical research workforce. Despite their potential impact, practical barriers prevent effective use of these resources. The Altman Clinical and Translational Research Institute (ACTRI) at the University of California San Diego (UCSD) developed and implemented of an institutional repository and support system to improve diversity supplement applications. The centralized repository and support system incorporated three strategies: (1) a secure web-based repository housing successful examples of supplements, (2) match making for diversity supplements and mentors, and (3) web-based resources for potential applicants. The repository was implemented in June 2021 and includes 51 supplement samples across 14 divisions of NIH as of November 2024. The repository has been accessed by 51 potential applicants since implementation in 2021. Few investigators have requested match making. Early indicators show a doubling in diversity supplement applications compared to pre-implementation period at UCSD. We outlined our approach to addressing some of the barriers in diversity supplement applications, which could provide a model for other institutions. Pending solutions to some of the lessons learned, coordinated efforts aimed at diversity supplements could be a practical approach toward a more diverse biomedical research workforce.

ABSTRACT IMPACT: Understanding how perceived discrimination affects Asian Americans can help stakeholders target subgroups that are at highest risk of discrimination-related behaviors and design culturally appropriate interventions to ensure equitable access to healthcare. OBJECTIVES/GOALS: The COVID-19 pandemic has exposed longstanding anti-Asian racism in the US. Yet, effects of discrimination on Asian American health are unknown, partly because diverse Asian American populations are analyzed in aggregate. We aim to understand how perceived discrimination affects healthcare utilization among different Asian American subgroups. METHODS/STUDY POPULATION: We examine the association of perceived discrimination with healthcare utilization using the California Health Interview Survey (CHIS). In the CHIS, respondents reported whether they would’ve gotten better medical care if they belonged to a different race. We examine the association between these responses and physician visits within the past year, in the survey years 2003, 2004 and 2016-2017. We adjust for covariates based on the Andersen Health Behavior model. Subsequent modeling examines potential mediating and moderating factors such as limited English proficiency, immigration status, income, and survey year. Asian American subgroups analyzed include Asian Indian, Korean, Chinese, Filipino, Vietnamese, Japanese, and other Asian. RESULTS/ANTICIPATED RESULTS: Results will highlight how perceived discrimination incentivizes or disincentivizes certain Asian subgroups to utilize healthcare. Asian American subgroups have differing and diverse experiences with discrimination due to their historical and cultural differences; results will elucidate how discrimination affects these subgroups. Results will be compared to non-Hispanic Whites, who represent the racial group least likely to experience discrimination in the US. Mediation and moderation analysis will help understand how traditionally cited factors for healthcare utilization interact with perceived discrimination on Asian Americans. DISCUSSION/SIGNIFICANCE OF FINDINGS: Asian American subgroups are understudied, despite Asian Americans being one of the fastest growing racial groups in the US. Understanding how perceived discrimination affects Asian Americans can help stakeholders target subgroups that are at highest risk of discrimination-related behaviors and design culturally appropriate interventions.

Objectives/Goals: To evaluate equity in utilization of free initial health evaluation (IHE) services among members of a limited health care program, the World Trade Center (WTC) Health Program (Program), to inform intervention development and provide insights for similar healthcare programs. Methods/Study Population: We included Program members who newly enrolled during 2012–2022, and who had an IHE or were alive for ≥ 1 year after enrollment. Program administrative and surveillance data collected from January 2012 to February 2024 were used. We evaluated two outcomes: timely IHE utilization (proportion of members completing an IHE within 6 months of enrollment) and any IHE utilization (proportion completing an IHE by February 2024). We described IHE utilization by enrollment year and various members’ characteristics and conducted multivariable logistic regression models to estimate adjusted odds ratios for IHE utilizations to identify factors related to potential inequities for the two member types: Responders, who performed support services, vs. Survivors, who did not respond but were present in the New York disaster area. Results/Anticipated Results: A total of 27,379 Responders and 30,679 Survivors were included. Responders were 89% male, 70% 45–64 years old at enrollment and 76% White. Survivors were 46% female, 54% 45–64 years old at enrollment, and 57% White. Timely IHE utilizations remained relatively stable (~65%) among Responders across time and increased from 16% among Survivors who enrolled in 2017 to 68% among Survivors who enrolled in 2021. Timely IHE utilization was lower for younger members (enrolled Discussion/Significance of Impact: This study highlights Program achievements and gaps in providing equitable IHE services. Strategies to improve members’ equitable IHE utilization can include: adopt/expand flexible scheduling; increase non-English language capacity and cultural competency; and facilitate transportation/assistance for members with accessibility barriers.

OBJECTIVES/GOALS: Community and other stakeholder engagement (CSE) is critical for relevant and equitable clinical research, yet implementation poses challenges. This study delineates the perspectives of scientists and diverse stakeholders regarding facilitators and challenges in CSE, its perceived value, and their recommendations for successful CSE. METHODS/STUDY POPULATION: The Tufts CTSI Pilot Studies Program requires applicants to propose a plan for CSE while implementing the award, including which stakeholders (SHs)—community members, clinicians, and others affected by the research--will be involved and at what stages. This qualitative study assessed the experiences of both Principal Investigators (PIs) and SHs engaged in pilot projects from three cohorts of awardees (2019-21). Recruitment targeted one PI and one SH per project. Semi-structured interviews explored their CSE experiences, including facilitators, challenges, meaningfulness, perceived impact, intent to participate in CSE in future studies, as well as recommendations for funders, research support organizations, and investigators. Inductive consensus-based coding and thematic analysis was employed. RESULTS/ANTICIPATED RESULTS: Fourteen PIs from different pilot projects and a SH from five of these projects participated. Almost all PIs (92%) had over six years of experience, but two-thirds (67%) had little or no experience with CSE. Four SHs self-identified as representatives of community organizations and one as a clinician scientist. CSE was a “win-win” for both PIs and SHs, and all PIs intended to involve SHs in other research studies. Three facilitators were identified as fostering effective CSE (e.g., PI access to CSE expertise while conducting the project), while four challenges hindered it (e.g., limits on SH capacity and CSE funding). SHs advised scientists to build authentic, sustained relationships, and PIs and SHs provided three actionable recommendations for funders and research support organizations to deepen and expand CSE. DISCUSSION/SIGNIFICANCE: Perspectives of scientists and SHs engaged in research projects are vital for expanding and sustaining effective CSE in research. Funders and research support organizations can enhance their strategies for CSE integration in clinical and translational research by incorporating these diverse views to ensure the research achieves maximal impact.

OBJECTIVES/SPECIFIC AIMS: Opioid prescribing is common and increasing in certain areas of the country with known risk of misuse and dependence. Our study examined the association of opioid prescription at discharge after hospitalization for acute coronary syndrome (ACS) or acute decompensated heart failure (ADHF) with emergency department (ED) care or all-cause readmission, intended healthcare utilization (follow-up with physician within 30 d of discharge and cardiac rehab participation), and all-cause mortality. METHODS/STUDY POPULATION: The Vanderbilt Inpatient Cohort Study is a prospective cohort of hospitalized patients age >18 enrolled with either ACS or ADHF between 2011 and 2015 (index hospitalization). We then excluded those who died during the index hospitalization, patients with hospitalization <24 hours, patients discharged to hospice care, or those who underwent coronary artery bypass surgery because of the high probability of receiving opioids. In addition, we limited the analyses to patients whom we had complete covariate data. The primary predictor variable was an opioid prescription at the time of hospital discharge. We collected healthcare utilization behavior for 90 days after discharge, and mortality data until March 8, 2017. Time-to-event analysis using Cox proportional hazard models was performed for both unintended healthcare utilization behavior and mortality outcomes. Logistic regression was performed for intended healthcare utilization (adherence to follow-up appointments and cardiac rehabilitation). All models were adjusted for demographic data, opioid use prior to index hospitalization, severity of illness, and healthcare utilization prior to the index hospitalization. RESULTS/ANTICIPATED RESULTS: There were 501 patients discharged with an opioid prescription and 1994 with no opioid prescription at discharge. Among patients with opioids at discharge 235 (47%) experienced unplanned healthcare events (71 ED visits and 164 readmissions) and among nonopioids patients 775 (39%) experienced unplanned healthcare events (254 ED visits and 521 readmissions) (aHR: 1.06, 95% CI: 0.87, 1.28). Patient mortality in the opioid group was 131 Versus 432 in the nonopioid group (aHR: 1.08, 95% CI 0.84, 1.39). Patients in the opioid at discharge group were less likely to attend follow up visits or participate in cardiac rehab (OR: 0.69, 95% CI 0.52, 0.91, p=0.009) compared with those not discharged on opioid medications. Sensitivity analysis of patients who were prescribed prehospital opioids (including prehospital opioids in the exposure group with postdischarge opioids) did not reveal a statistically significant increase in mortality (aHR: 1.09, 95% CI 0.91, 1.31) or unintended healthcare utilization (aHR: 1.12, 95% CI 0.89, 1.41) among opioid users. DISCUSSION/SIGNIFICANCE OF IMPACT: Morbidity and mortality related to opioid use is a public health concern. Our study demonstrates a statistically significant reduction in physician follow-up and participation in cardiac rehab among opioid users, both of which are known to decrease patient mortality. We did not find a statistically significant increase in unplanned healthcare utilization or mortality. Sensitivity analysis combining prehospital and posthospital opioid prescriptions did not reveal a statistically significant association between opioid use, hospital readmissions, or mortality. The hospital provides unique patient interactions where providers can make significant medical changes based on their patient’s clinical status. Continuing to understand the association between opioid use, healthcare utilization, morbidity, and mortality in recently hospitalized cardiac patients will provide data to support reduction in total opioid dose to improve clinical outcomes.

OBJECTIVES/GOALS: Neonatal hypoxic-ischemic encephalopathy (HIE) is an acute neurologic syndrome where decreased blood flow and oxygen to the brain causes acute and chronic brain dysfunction. The only proven neuroprotective intervention for HIE is hypothermia treatment started within 6 hours of birth and 50% of survivors have long-term deficits. METHODS/STUDY POPULATION: Pre-clinical adult stroke studies demonstrated that vagus nerve stimulation (VNS) has anti-inflammatory effects and attenuates brain damage. Transcutaneous auricular VNS (taVNS) is safe and feasible in infants and may improve the motor skill of bottle feeding. We hypothesize that a combined hypothermia-taVNS treatment shortly after HIE birth will have neuroprotective effects, improve motor function, attenuate infarct volume inflammation compared to hypothermia alone. The HIE model includes ligation of the right common carotid artery in postnatal day 7 (P7) rats followed by 90min hypoxia (8% oxygen) and 2hr hypothermia. taVNS or sham taVNS was administered using a bipolar electrode placed on the auricular concha region for 30min, [30sec trains, 0.5msec duration, 20Hz frequency, followed by 4.5min breaks] RESULTS/ANTICIPATED RESULTS: Experimental groups include +HIE/+taVNS, +HIE/-taVNS, and -HIE/-taVNS. To assess motor function, grasping reflex and forelimb grip strength tasks were assessed prior to surgery through P10. Infarct volume was assessed at 72h after injury by staining coronal sections with cresyl-violet. Thirty-four rat pups underwent surgery with an 8.82% mortality rate. taVNS was well tolerated by the P7 rats when delivered below perceptual threshold (0.4-1.1mA). There was no difference in elementary motor function or infarct volume between any group. DISCUSSION/SIGNIFICANCE: Future studies will include 2.5hr hypoxia for a more severe brain injury and a -HIE/+taVNS control group. These initial pre-clinical studies in neonates are important in determining whether taVNS may translate as a treatment to improve outcomes after neonatal HIE.

Objectives/Goals: Access to accurate public health information is an essential component to ensuring health equity. We launched our social media channels on Instagram, Facebook, and TikTok to highlight, engage with, and bring culturally tailored and language appropriate health and research information to our target communities. Methods/Study Population: Monitoring engagement patterns with our content on each platform influenced the development of a range of innovative campaigns in both English and Spanish that were informed by our core values of inclusivity, trust-building, ongoing bidirectional communication, and co-creation. These three platforms were chosen to ensure reach and engagement with the different demographics within our target populations. The campaigns included those that provided relevant and accurate health information, highlighted the diversity of our team, uplifted our community partners, and gave voice to our community members. This content included health-related infographics, mini-documentary reels, video essays, interviews, and photos. Results/Anticipated Results: We assessed effectiveness, reach, and engagement based on the robustness of the analytics for each platform. Facebook content, the majority of which is in Spanish, appealed more to older, Latino community members. TikTok content appealed more to younger (under 35), primarily English-speaking community members, while Instagram appealed more to organizational partners and community health workers. A 2023 trendline analysis of average monthly Instagram content reach and interactions indicated a moderate-to-strong relationship between our tailored content and audience engagement. Storytelling techniques consistently outperformed other content types across platforms, and community partner collaboration drastically enhanced our visibility, reach, and further validated our approach. Discussion/Significance of Impact: Social media has become increasingly central to bidirectional information dissemination. Implementing tailored strategies and leveraging storytelling techniques is an effective means of engaging diverse audiences, enhancing public health communication, and building and maintaining trust by providing accurate, accessible information.

OBJECTIVES/GOALS: Real-world data (RWD) may offer insights into mental health treatment as usual and illuminate targets for implementation and translation. This requires strong research-community partnerships (RCP). In this presentation, we will highlight key components of an ongoing RCP in leveraging RWD to advance translational science. METHODS/STUDY POPULATION: The RCP was formed to develop an infrastructure for NAMI Chicago, a community-based organization that oversees a city-wide social services helpline, to support collection of RWD data to understand whether NAMI helpline support services and referrals meet callers’ emotional and physical needs. This RCP includes three entities: NAMI Chicago, UIC’s Center for Clinical and Translational Science’s Community Engagement and Collaboration (CEC) Core, and UIC’s Institute for Health and Research Policy’s Data Management Core (DMC). From a preliminary review of case notes, this case study details concrete examples that fit into Brookman-Frazee etal. (2012)’s RCP framework to illustrate the trajectory of this partnership through its formation, execution of activities, and sustaining NAMI Chicago’s data capacity. RESULTS/ANTICIPATED RESULTS: In the formation of this RCP, we identified our joint goal of creating a database infrastructure to link NAMI Chicago’s existing helpline data with a database co-created in REDCap through APIs. Based on the identified joint goal, we defined our roles/responsibilities that best aligned with our own individual expertise to execute the necessary operational processes. The RCP is currently executing the activities to create this data infrastructure. Barriers included delays in securing a computing environment and enablers included an established long-standing relationship between NAMI Chicago and CEC. Distal outcomes of this RCP include increasing NAMI Chicago’s capacity to systematically use RWD to better inform their practices and identify barriers in accessing social service resources in Chicago. DISCUSSION/SIGNIFICANCE: The identification of enablers, barriers, and the necessary operational processes and activities will outline a “blueprint” for other institutions and community organizations to successfully utilize RWD to understand mental health practices and advance translational research.

OBJECTIVES/GOALS: In triple negative breast cancer (TNBC), obesity is associated with poor outcomes. Adipose stem cells (ASCs) from obese patients (obASCs) secrete higher levels of adipokines compared to ASCs from lean individuals. Leptin, one of these adipokines, has been implicated in many cancers. This study seeks to examine the role of leptin signaling in TNBC. METHODS/STUDY POPULATION: Previous work in conjunction with a collaborating lab has shown that leptin signaling promotes metastasis and increased expression of epithelial-mesenchymal transition (EMT) markers in triple negative breast cancer cell lines. This project expands upon this work through using both patient-derived cell lines and and patient-derived xenografts (PDX), and examines the role of leptin signaling both in vitro and in vivo. To determine the effects of obesity upon a PDX model of TNBC, a high fat diet was used to induce obesity in vivo. A pharmacological inhibitor of the leptin receptor was used to test the requirement for leptin signaling both in vivo and in vitro. RESULTS/ANTICIPATED RESULTS: Exposure to conditioned media harvested from obASCs increased the percentage of TNBC cells that expressed cancer stem cell markers, whereas exposure to an inhibitor of the leptin receptor decreased the percentage of cells with cancer stem cell markers. PDX tumors implanted into mice with diet-induced obesity had an increased volume compared to tumors implanted into lean controls. Further analysis will be conducted on metastasis, circulating tumor cells, and survival in both lean and obese mice. DISCUSSION/SIGNIFICANCE: Understanding the complex signaling events in the obese tumor microenvironment is essential, as these molecular differences may contribute to different outcomes for obese and lean individuals with triple negative breast cancer. Therefore, study of the crosstalk between obASCs and TNBC cells is critical.
