OBJECTIVES/GOALS: This study aims to develop a method to examine whether blood-borne CNS-EV metal cargoes can serve as reliable biomarkers of CNS metal load and reveal a link between metal load and ALS development (i.e., neurodegenerative disease development). METHODS/STUDY POPULATION: CNS-EVs were isolated from human blood and plasma samples via direct immunoprecipitation using biotinylated antibodies for proteins known to be expressed in neurons (Contactin-2, i.e.) and astrocytes (glial-glutamate-aspartate-transporter, i.e., GLAST). Once isolated, protein concentrations in the EV samples were analyzed via ELISA assay, EV abundance was measured using ViewSizer Nanoparticle Tracking analysis, and EVs were visualized via Transmission Electron Microscopy. EVs were then analyzed for metal contents using a Perkin-Elmer NexION 350S via an ICP-MS/MS dynamic reaction cell method. RESULTS/ANTICIPATED RESULTS: Preliminary results demonstrate that it is feasible to quantify the metal contents of these CNS-derived EVs, particularly in terms of toxic metals known to be associated with neurodegenerative disorders, including copper, zinc, lead, aluminum, manganese, and iron. DISCUSSION/SIGNIFICANCE: CNS-derived EVs isolated from peripheral blood draws show promise as a potential biomarker of real-time metal load in the brain and spinal cord, with promising applications in predicting future development of neurodegenerative disorders (i.e., ALS) among patients with relevant elevated CNS metal loads.

OBJECTIVES/SPECIFIC AIMS: The Title V Cooperative Project between the University of Puerto Rico- Medical Sciences Campus (UPR-MSC) and Universidad Central del Caribe (UCC) has trained US, GS and F (participants) of HSPs to engage them in CTR. METHODS/STUDY POPULATION: First stage of the training sessions (TS) dealt with the theory of CTR. After TS and responding to their research interests, as answered in a questionnaire, the participants formed a CTMT, under the mentorship of a well-established CT researcher. This, as a prelude to their hands-on experiences in Intensive Development and Experiences in Advancement of Research and Increased Opportunities (IDEARIO), for which a research proposal is needed. RESULTS/ANTICIPATED RESULTS: Five (5) CTMTs were formed in different research areas – cardio, neuro, liver, renal, Zika–, as submitted in their research concept papers.Eight (8) CT researchers are currently mentoring 2 US, 7 GS and 6 F of HSPs through the CTMTs. They have submitted a research proposal, as a bridge between the theory in the TS and the practice in IDEARIO. Five (5) proposals were received and 2 of them approved, while the other 3 are in the evaluation process. We will present the composition, research topics, development of research and the feedback of participants in IDEARIO and CTMTs. DISCUSSION/SIGNIFICANCE OF IMPACT: The CTMTs and their respective proposals are effective strategies for the mentoring of US, GS and F in CTR.

OBJECTIVES/SPECIFIC AIMS: In this pilot case-control study, the metabolome was quantified in subjects with previously measured serum and clinical biomarkers. The serum metabolome was then integrated with existing serum and clinical biomarkers of WTC-exposed firefighters to identify pathways significant to loss of lung function following acute PM-exposure. This robust subset of metabolite and serum biomarkers may be clinically relevant to predicting progression to lung disease in a larger cohort. METHODS/STUDY POPULATION: Serum drawn within 6 months of 9/11 was analyzed in this pilot. Clinical measures were obtained from electronic medical records. Never-smoking, male, WTC-exposed firefighters with normal pre-9/11 lung function were segregated based on FEV1 percent predicted (FEV1 %Pred) at symptomatic presentation. Cases of WTC-LI (FEV1 %Pred <LLN, n=15) and controls (n=15) were identified from previous cohorts. Ultrahigh performance liquid chromatography tandem mass spectroscopy quantified the metabolomic fingerprints of a group with previously assessed (by multiplex panels; ELISA and Luminex) serum chemokines and cytokines. High-dimensional data analysis and dimension reduction techniques integrated metabolites, cytokines, chemokines, and clinical data to identify pathways of WTC-LI on curated data. Random Forest (RF) out-of-bag estimated success rates were used to measure classification utility of the refined biomarker profile. Principal components analysis (PCA) was used to visualize class separation produced by the refined profile. RESULTS/ANTICIPATED RESULTS: Of the 765 metabolites detected, 580 metabolites were quantified in more than 80% of subjects/group with relative standard deviation ≥15%. Relevant chemokines, cytokines, and clinical biomarkers were included based on previously established clinical importance. Initial PCA explained 34.7% of the variance in the first 3 components. RF was used to identify the top 5% of biomarkers important to class separation. RF of the refined biomarker profile correctly classified cases and controls with a 96.7% estimated success rate. A PCA of the refined metabolic profile now explained 46.2% of the variance in components 1–3, demonstrating improved class separation. Differentiators between cases of WTC-LI and controls included elevated sphingolipids in cases of WTC-LI. The metabolic-inflammatory serum biomarkers MDC, Apo AI, GM-CSF, and heart rate play an important role in class separation. Phospholipids and lysolipids also appeared to differentiate cases of WTC-LI from controls. Specifically, several glycero-phosphatidylcholines (GPC) were elevated in cases of WTC-LI. DISCUSSION/SIGNIFICANCE OF IMPACT: High-dimensional data analysis on the metabolic fingerprints, serum, and clinical biomarker data of a subset of WTC-exposed 9/11 rescue workers has identified pathways associated with the loss of lung function. Sphingolipids, known to function as inflammatory signaling mediators, are thought to play important roles in lung function under both physiological and pathological conditions. Changes in sphingolipid metabolism have been linked to several pulmonary disorders, including asthma, COPD, and acute lung injury. Interestingly, a relation between sphingolipid metabolism and the metabolic-inflammatory pathway is suggested by similarities observed in PCA. Findings of elevated GPCs are similar to COPD literature. Higher levels of GPCs could correspond to elevated levels of lysophosphatidic acid (LPA), a ligand of RAGE. RAGE is a known proinflammatory mediator; LPA species have well-described roles as lipid signaling molecules, function as synthetic intermediates in other metabolic pathways, and were found to be predictive of WTC-LI. Since metabolites are more proximal markers of disease processes, metabolites could capture the complexity of past exposures and, therefore, may better inform treatment. These pathways warrant further investigation into their mechanisms and therapeutic importance.

OBJECTIVES/GOALS: There are notable disparities in cervical cancer screening. Theobjective of this study was to examine knowledge, screening practices, attitudes towards cervical cancer screening, and willingness to adopt screening innovations such as self-sampling and HPV rapid testing for cervical cancer among Hispanic women in Lake County, Indiana. METHODS/STUDY POPULATION: This mixed-methods study encompassed an online cross-sectional survey (n=231) and in-depth interviews (n=9) of individuals with a cervix aged 21-65 residing in Lake County, Indiana. Outcome variables focused on cervical cancer knowledge, willingness to adopt self-sampling, and willingness to adopt HPV rapid testing. Descriptive statistics included frequencies and percentages. A cervical cancer knowledge score was computed from 7 questions. Scores below the mean 3.62 were labeled ‘low’ while higher scores were ‘high’. We also examined associations between demographic and outcome variables. Quantitative analysis was conducted using SPSS software. Qualitative analysis was conducted using NVIVO software to thematically analyze interviews using deductive and inductive coding techniques. RESULTS/ANTICIPATED RESULTS: Majority of participants identified as Hispanic (58%), aged 31 or older (58%). While 80.5% reported being screened for cervical cancer, only 44.6% demonstrated ‘high' cervical cancer knowledge. 89.6% felt screening is important as emphasized in qualitative findings for its preventive value. Over half were willing to take their vaginal swab in clinic (55.8%) and at home (51.9%). However, among the Hispanic/Latinx groups reluctance to adopt self-sampling was notable (56.7% in clinic and 62.7% at home). Qualitative analysis revealed concerns about test accuracy. Willingness to use a hypothetical HPV rapid had higher acceptance (69.7%), with 52.2% in the Hispanic/Latinx group. Qualitative findings highlight benefits like increased screening access, comfort, and convenience offered by an HPV rapid test. DISCUSSION/SIGNIFICANCE: Hispanic/Latinx women in the sample were less willing to adopt cervical cancer screening methods such as self-sampling and rapid testing compared to non-Hispanic whites. Despite being considered beneficial for testing among vulnerable populations, our study found limited acceptance from these populations for various reasons.

OBJECTIVES/SPECIFIC AIMS: Objective: The Rockefeller University Center for Clinical and Translational Science (RU-CCTS), Clinical Directors Network (CDN), and Carter Burden Network (CBN), a multisite senior services organization serving East Harlem, NY, formed a community-academic partnership to examine the use of a simple validated surrogate measure of overall health status and frailty in this population. Many CBN seniors are racial/ethnic minorities, low-income, and suffer from multiple chronic conditions, depression and food insecurity. Multiple biological, musculoskeletal, psychosocial and nutritional factors contribute to frailty, which has been defined variously in senior health outcomes research. The CTSA-funded Pilot Project aims to: (1) Engage CBN seniors and stakeholders in priority-setting, joint protocol development, research conduct, analysis, and dissemination; (2) Characterize the health status of the CBN seniors using validated measures; (3) Establish database infrastructure for current and future research; (4) Understand how health and senior activities information can be used to create programs to improve senior health. METHODS/STUDY POPULATION: Methods: (1) CEnR-Navigation, a collaborative program/process that consists of semistructured meetings and activities facilitated by expert Navigators, was used for partnership development and to engage Carter Burden seniors to refine priorities and research questions, provide feedback on study design and conduct, and analyze and disseminate results. (2) Standard physical measurements and validated survey instruments were used to collect health information; target enrollment is 240 seniors across 2 sites (1 hosted within a subsidized housing facility and Social Model Adult Day Program). (3) A REDCap-based platform was designed for data capture and import. Individual attendance at senior activities for the prior year was extracted from existing records. The primary outcome is frailty, as measured by validated walk/balance tests (Short Physical Performance Battery). Secondary outcomes include measures of engagement, and association of use of services/activities with the primary outcome. RESULTS/ANTICIPATED RESULTS: (1) In total, 29 residents and 14 other stakeholders engaged in partnership-building, study design and implementation. (2) From May to November 2017, 98 participants were enrolled from site 1 (a residential site). Enrollment at site 2 (a senior center), begun in November, is projected for February completion. Characteristics of site 1 participants: median age=63.6 years; Hispanic, 44.90% (44); White, 13.89% (10), Black, 62.50% (45); Asian, 4.17% (3); American Indian or Alaskan Native, 2.78% (2), and Other, 16.67% (12). Educational attainment: 51.04% (49) had not completed high school; 19.79% (19) were high school graduates; 18.75% (18) completed some college, and 10.42% (10) were college graduates. For the 85 participants reporting annual income: 64.71% (55) reported <$10,000; 28.24% (24) reported $10,000–$15,000; 7.06% (6) were among the ranges from $15,000 to $50,000. The average body mass index (BMI) was 30, which is obese. For 83.67% (82) of site 1 participants, the BMI was in the range of overweight or obese. Half of participants (49) reported health literacy barriers in the Single Item Health Literacy Survey. Demographics and Frailty assessments (walk and balance tests) for participants enrolled at both sites will be reported. (3) Activity participation data for July 2016–November 2017 were recovered for 507 sessions at site 1 and are being analyzed. DISCUSSION/SIGNIFICANCE OF IMPACT: Here we report progress in developing a sustainable community-academic partnership, infrastructure and research capacity with the CBN senior services organization, and characterizing this at-risk population, of whom 71% have a high school education or less, 93% live in extreme poverty, and 84% are overweight or obese. A simple validated frailty measure in seniors will enable the acceleration of community-based translational research addressing senior health, and examine changes in this measure in relationship to the utilization of senior services.

Several reports have shown that doctoral and postdoctoral trainees in biomedical research pursue diverse careers that advance science meaningful to society. Several groups have proposed 3-tier career taxonomy to showcase these outcomes. This 3-tier taxonomy will be a valuable resource for institutions committed to greater transparency in reporting outcomes, to not only be transparent in reporting their own institutional data but also to lend greater power to a central repository.

The potential utilization of a cold-contact approach to research recruitment, where members of the research team are unknown to the patient, has grown with the expanded use of electronic health records (EHRs) and affiliated patient portals. Institutions that permit this strategy vary in their implementation and management of it but tend to lean towards more conservative approaches. This process paper describes the Medical University of South Carolina’s transition to an opt-out model of “cold-contact” recruitment (known as patient outreach recruitment or POR), wherein patients can be contacted so long as they do not express an unwillingness to receive such communication. The work highlights the benefits of this model by explaining how it, in many ways, supports and protects autonomy, beneficence, and justice for patients. The paper then describes the process of standing up the recruitment strategy, communicating the change to patients and the community, and documenting study team contact and patient research preference. Data supporting increased access to potentially eligible patients of greater diversity as well as initial researcher feedback on perceived success of POR is also shared. The paper ends with a discussion of next steps to enhance the POR process via more detailed data collection and reengagement with community stakeholders.

Low-accruing clinical trials delay translation of research breakthroughs into the clinic, expose participants to risk without providing meaningful clinical insight, increase the cost of therapies, and waste limited resources. By tracking patient accrual, Clinical and Translational Science Awards hubs can identify at-risk studies and provide them the support needed to reach recruitment goals and maintain financial solvency. However, tracking accrual has proved challenging because relevant patient- and protocol-level data often reside in siloed systems. To address this fragmentation, in September 2020 the South Carolina Clinical and Translational Research Institute, with an academic home at the Medical University of South Carolina, implemented a clinical trial management system (CTMS), with its access to patient-level data, and incorporated it into its Research Integrated Network of Systems (RINS), which links study-level data across disparate systems relevant to clinical research. Within the first year of CTMS implementation, 324 protocols were funneled through CTMS/RINS, with more than 2600 participants enrolled. Integrated data from CTMS/RINS have enabled near-real-time assessment of patient accrual and accelerated reimbursement from industry sponsors. For institutions with bioinformatics or programming capacity, the CTMS/RINS integration provides a powerful model for tracking and improving clinical trial efficiency, compliance, and cost-effectiveness.

Objectives/Goals: The goal of this poster is to 1) describe the development of a graduate certificate program for community-engaged research for health (CEnRH) in a Clinical and Translational Science Awards-funded institution; 2) describe the initial impact of the program; and 3) discuss strengths, implications, and potential improvements for the future. Methods/Study Population: The CEnRH graduate certificate is a 12-credit, postbaccalaureate program offered at the University of Cincinnati co-created by faculty from the Community Engagement and Translational Workforce Cores of the CCTST with community partners. The goal is to support learning about community-engaged research (CEnR) and enhances capacity for academic-community partnered research. Student demographics are collected as part of university registration. Quantitative course evaluations are collected each semester. Program evaluations including qualitative data are collected from students enrolled in the program during and upon completion of the certificate. Results/Anticipated Results: The CEnRH curriculum includes 3 existing courses/electives in the College of Medicine and Psychology and three new courses in social justice and action research methodologies. Notably, the committee advocated for a scholarship to cover tuition for the certificate program to promote access for community partners. Since the fall of 2022, 17 students have enrolled in the CEnRH program, including 9 Faculty/Staff within CCTST institutions, 2 University of Cincinnati PhD Students, 5 Fellows, and 1 Community Member (who receives the scholarship). Notably, 24% of these students are from underrepresented minority backgrounds. Impact and evaluation data, as well as lessons learned, will be presented. Future directions for the CEnRH program will also be discussed. Discussion/Significance of Impact: The CEnRH is an impactful program for trainees, faculty, and staff who are planning to conduct CEnR, while also strengthening research capacity among community partners and advocates. This certificate program may be especially valuable to academic researchers as more funding agencies require community and stakeholder engagement in their proposals.

ABSTRACT IMPACT: The Independent Investigator Incubator program provides 1:1 mentoring from ‘super-mentors’ to enhance junior faculty careers in research. OBJECTIVES/GOALS: In 2014, the Indiana University School of Medicine (IUSM) in collaboration with the Indiana CTSI established the Independent Investigator Incubator (I3) Program. The I3 Program is designed to provide 1:1 mentoring for new research faculty during the crucial early years of their careers. Our goal is to provide an overview of the I3 design and 5-year data. METHODS/STUDY POPULATION: The I3 Program employs a resource-sharing, centralized design that provides concentrated 1:1 mentorship from a senior faculty ‘super mentor’ as well as other resources, such as grant writing support. Unlike many mentorship programs, I3 mentors closely interact with the mentees within the School and are compensated for their efforts (5% full-time equivalency per mentee, max of 15%). The number of ‘super mentors’ has grown from 6 to 15 faculty over 5 years, and mentors typically serve 4 to 5 mentees. Mentee applications are accepted on a rolling enrollment basis. The I3 mentees represent a diverse group based on sex, ethnicity, terminal degree, academic track, and discipline. Mentors and mentees have annual reviews through the program. RESULTS/ANTICIPATED RESULTS: In five years, 110 mentees have enrolled in the I3 program. Upon entering, 53% had no external funding, 28% had internal funding, 12% had K-awards, 7% had R03/R21 awards. Over the first five years, 75% have received extramural funding. The median funding was $340,000 with nearly a third of mentees securing grants > 1 million in direct costs. For mentees who joined the program in its first three years (n=59), the average time to a notable extramural grant (defined as a NIH or foundation grant >$300K direct costs) was 2.2 years (median - 2.6 years). Nearly all mentees were satisfied with their mentor pairing based on the mentor’s ‘availability’ and ‘valuable feedback,’ and all mentees wanted the mentoring relationship to continue DISCUSSION/SIGNIFICANCE OF FINDINGS: Since 2014, the I3 Program has had a positive impact on the careers of junior faculty at IUSM as determined by faculty satisfaction and funding metrics. Future focus areas will include developing criteria/models for graduating from the program to balance fiscal sustainability with mentee needs during their transition to mid-career.

OBJECTIVES/SPECIFIC AIMS: The study aims to determine the current clinical research training interventions of MD-PhD programs and how effective they are in promoting clinical research self-efficacy. METHODS/STUDY POPULATION: A national survey of MD-PhD trainees was conducted in 2018 to identify clinical research training methods and self-efficacy for clinical research skills. MD-PhD program directors and coordinators from 108 institutions were asked to distribute the survey to their students. Responses were received from 61 institutions (56.5%). Responses were obtained from 647 MD-PhD students in all years of training, representing 17.9% of the 3613 possible participants at the 61 medical schools represented. No compensation was provided for this study. RESULTS/ANTICIPATED RESULTS: The primary methods of clinical research training reported by students included didactics, mentored clinical research, didactics plus mentored clinical research, didactics plus clinical research practicum, and didactics plus mentored clinical research plus clinical research practicum. A quarter of all participants reported having no clinical research training. Clinical research self-efficacy was then correlated with the amount of clinical research training. Students exposed to no clinical research had the lowest self-efficacy in clinical research skills and students experiencing didactics plus mentored clinical research plus clinical research practicum had the highest perceived self-efficacy in clinical research domains. DISCUSSION/SIGNIFICANCE OF IMPACT: This is one of the first studies assessing clinical research training methods for MD-PhD students and assessing their efficacy. We found that of all students questioned, 25% mentioned had not received any type of clinical research training. The remaining students identified 5 research training methods that institutions currently use. This work highlights the importance of clinical research experience students need to improve their self-efficacy, a major influence on research career outcomes.

OBJECTIVES/GOALS: To examine pharmacy students’ and patients’ perspectives on use of an automatic pill dispenser (APD) and adherence device, and secondly, to identify patient characteristics impacting selection of an APD. This knowledge will assist pharmacists in making appropriate device recommendations that improve medication adherence and effectiveness. METHODS/STUDY POPULATION: One hundred fifty-three pharmacy students participated in a personal APD simulation, living the life as a person taking medication. Students then each identified an actual patient exhibiting medication nonadherence from pharmacy records at their work setting, provided them with an APD free of charge and instructed them on its use. The students later interviewed their patients and reported on their patients’ ability to use the APD, as well as their perspectives (likes and dislikes) on the features of the device. Students identified individual patient characteristics associated with successful use of the APD. This new knowledge will aid these future pharmacists in making recommendations for medication adherence devices for their patients. RESULTS/ANTICIPATED RESULTS: In general, patients perceived more difficulty with use of the 10 APD features than did students. Over half of the patients indicated that the following features were a distinct advantage in adherence: individual medication compartment size, method of loading medications, alarm, flashing light, ability to lock the dispenser, and method of retrieving the medication from the device. Patients felt that the biggest disadvantage was its bulky size and lack of portability. In spite of individual difficulties with use, the research findings showed that persons who are elderly, homebound, have memory problems, take multiple medications and/or have complex regimens are most likely to benefit from the device features and exhibit improved adherence to their prescribed medication regimen. DISCUSSION/SIGNIFICANCE: Medication adherence rates in the U.S are agreed upon to be about 50% - highly relevant to healthcare practitioners since several studies suggest a correlation between adherence and improved health outcomes. Pharmacists must be knowledgeable about non-adherence tools and consider patient characteristics when recommending an adherence aid.

OBJECTIVES/GOALS: To establish the root causes of vaccine hesitancy in populations who have less equitable access to health and healthcare services, and experience healthcare inequities, related to the environmental and social determinants of health, through community engagement and conversations, collaboration, circulation, and communication. METHODS/STUDY POPULATION: Existing data from a cross-sectional survey, vaccine hesitancy (VH) parent study, entitled 'Western New York (WNY) COVID-19 Collaborative to Promote Vaccine Acceptance,' conducted July to November 2022, after IRB approval, will be qualitatively analyzed. In the parent study, surveys were administered in WNY community congregations and community centers to individuals that historically have less equitable access to healthcare resources and may encounter health and healthcare disparities. Minorities, in urban and rural areas, age eighteen and older were identified through the NYS Department of Health’s Immunization Information System for daily vaccination rates. A qualitative analysis, promoting fact base HL, and building an inferential statical machine learning tool are the next steps. RESULTS/ANTICIPATED RESULTS: We anticipate the results to show an interplay of multiple factors, including personal, cultural, historical, social, and political, and varies depending on circumstances of time, place, and the type of vaccine being offered. Additionally, a lack of awareness or understanding of vulnerabilities and seriousness of vaccine-preventable diseases, lack of trust in health care providers, social norms, distrust of the healthcare system, biomedical research, and government policy, limited knowledge and understanding of vaccine safety and efficacy, and fear/uncomfortable with needles, as well as the less addressed environmental and social determinants of health associated with racial/ethnic minorities in communities with limited resources may also contribute to VH and less favorable health outcomes. DISCUSSION/SIGNIFICANCE: Identifying people who historically have less equitable access to healthcare resources and may be more likely to resist healthcare services, due to distrust in the system is important. Creating and evaluating an innovative tool to predict refusal of public health interventions is essential to avoid spreading preventable diseases.

OBJECTIVES/GOALS: The purpose of this study was to develop behavioral economic purchase tasks to assess interest in CM as a function of treatment cost and perceived effectiveness of CM as a function of abstinence incentive size in alcohol drinkers. Additionally, these purchase tasks are being assessed for their clinical utility in an ongoing clinical trial. METHODS/STUDY POPULATION: Alcohol drinkers recruited from Amazon Mechanical Turk completed behavioral economic purchase tasks measuring demand for CM based on targeted abstinence intervals and treatment effectiveness and alcohol use disorder severity assessments. Nonlinear mixed effects modeling was used to fit demand curves and assess the relationship between individual characteristics and demand metrics for CM. Ongoing analyses involve administering the same behavioral economic purchase tasks in heavy alcohol users in the ongoing clinical trial, which is aimed at reducing alcohol use through remotely implemented CM. RESULTS/ANTICIPATED RESULTS: Mechanical Turk participants reported higher probability of abstinence when offered larger incentives and required larger incentives when duration of abstinence required to earn the incentive was increased. Additionally, willingness to pay for treatment increased as effectiveness of treatment increased. It is anticipated that these patterns will be observed in the clinical trial participants. DISCUSSION/SIGNIFICANCE: Abstinence interval and treatment effectiveness are important features to consider when developing effective CM for widespread use, as these variables affected participants likelihood of being abstinent and their interest in treatment. We are currently working on verifying the results of these assessments in clinical trial participants.

OBJECTIVES/GOALS: This poster will explore lesion-symptom mapping and resting state functional magnetic resonance imaging (rsfMRI) in participants with aphasia. This analysis aims to reveal the behavioral impact of distinct lesions to the left inferior frontal gyrus (LIFG) and the potential for rsfMRI to provide evidence of cortical reorganization. METHODS/STUDY POPULATION: The analyses will be conducted on a small sample of approximately six participants with post-stroke language impairment (i.e., aphasia) recruited as part of an ongoing study. Lesion load in the anterior LIFG (aLIFG), consisting of the orbital (BA 47) and triangular (BA 45) parts, and the posterior LIFG (pLIFG), consisting of the opercular part (BA 44) will be correlated with performance on tasks of semantic and phonological processing. Functional connectivity will be determined between regions of interest (i.e., anterior superior temporal, posterior middle temporal, angular, and supramarginal gyri) in the left and/or right hemispheres based on rsfMRI data. RESULTS/ANTICIPATED RESULTS: Lesion load in the aLIFG is expected to correlate to performance on the semantic task, whereas lesion load in the pLIFG is expected to correlate to performance on the phonological task. For participants whose behavioral performance exceeds expectations based on lesion load (e.g., larger aLIFG lesion load, yet better semantic task performance), rsfMRI connectivity is expected to be greater (e.g., between the posterior middle temporal and angular gyri), suggesting cortical reorganization. DISCUSSION/SIGNIFICANCE: If our hypotheses are supported, our results will corroborate evidence of a functional spectrum (i.e., semantic-phonological) in the LIFG. Future work will compare rsfMRI connectivity to neurotypical controls and sites of connectivity may be used as targets in studies of non-invasive brain stimulation as an adjuvant to behavioral therapy.

OBJECTIVES/GOALS: A new researcher-facing module to support community engaged research has been added to the updated COALESCE website and user traffic was tracked since last reporting. We describe the process of development and the features of the new module, past 2-year traffic, and plans to develop a community facing module. METHODS/STUDY POPULATION: We monitored the number of unique users of COALESCE (teamscience.net) between 2017 and 2019 to determine if traffic slowed, stayed the same, or increased since teamscience.net was physically updated to function on mobile devices. In December 2019, a new module was launched to introduce researchers to the stages of team science community engaged research. To develop the module, we collaborated with academic partners at University of Illinois-Chicago to identify 3 local historic research case studies in and to characterize how each exemplified a team science stage: assembly, launch, or maturation. After interviewing key team members from each study, we iterated storyboards and scripts in collaboration with community engaged research experts and case study team members. The module was built, tested, and launched. RESULTS/ANTICIPATED RESULTS: In the 6 years between 2011 through 2017, the site attracted 16,016 unique visitors (approximately 2699 per year). In 2 years from 2017 through 2019, since the modernization of the website, user traffic has held steady or grown, attracting 6992 unique visitors (approximately 3496 per year). Our newly posted researcher-facing module highlights team assembly in the case a task force charged with reducing disparity in breast cancer outcomes in Chicago, team launch in a study to improve asthma management in a local FQHC, and team maturation in a study comparing clinic-based to public school-based treatment of disruptive behavior. We will soon create a companion community-facing module and resources to address identified needs for community partners engaging in research with academic institutions. DISCUSSION/SIGNIFICANCE OF IMPACT: COALESCE (teamscience.net) remains the first and only open-access, online training in team science for health professionals. Recent updates have improved usability and expanded available resources. We launched a comprehensive module for academics interested in community engaged research; future work will develop parallel community facing resources.

OBJECTIVES/SPECIFIC AIMS: The purpose of this study is to use the baboon as a novel animal model for breath research and to identify and characterize baboon breath metabolites that reflect cardiometabolic function to inform us in the development of a noninvasive, cost-effective, and repeatable point-of-care diagnostic breath test. METHODS/STUDY POPULATION: Blood and urine was collected from control and IUGR at the approximate age of 3.5 years. Both groups were then placed on a high fat, high sugar, high salt diet for 7 weeks, after which blood, urine, and breath were collected. The breath samples were then subjected to comprehensive, 2-dimensional gas chromatography coupled with time-of-flight mass spectrometry. Using ChromaTOF software, breath VOCs were identified with at least an 80% spectral match against the National Institute of Standards and Technology (NIST) chemical reference library. The raw data were then statistically analyzed using MetaboAnalyst. We then interrogated multiple online databases to characterize and identify the role of VOCs that were present in both control and IUGR groups. RESULTS/ANTICIPATED RESULTS: Preliminary analyses of the breath VOCs indicate differences in expression between sexes and in control Versus IUGR groups. These results indicate unique “breath signatures.” Further analysis of the breath VOCs reveals the presence of metabolites that are involved in β-oxidation and oxidative stress pathways. DISCUSSION/SIGNIFICANCE OF IMPACT: This breath study, a first of its kind, will develop the baboon as a superior animal model for breath biomarker research. Our observed unique “breath signatures” indicate changes in lipid metabolism and oxidative stress pathways, which we hypothesize are the early metabolic changes at the cellular level that are not yet reflected in clinical lab measures. Future directions include analyzing breath VOCs that did not meet 80% spectral match, validation using SPME technology and commercial standards, and initiating a human pilot study in clinically obese, at-risk children in collaboration with physicians at the Children’s Hospital of San Antonio to develop a noninvasive, cost-effective, rapid, and repeatable point-of-care diagnostic breath test.
