Objectives/Goals: Physical activity (PA) is critical to improving the health and well-being of patients with congenital heart disease (CHD); however, rates of PA, specifically in children and adolescents with CHD, remain significantly lower than the general population. Our goal was to understand what factors influence rates of PA in children and adolescents with CHD. Methods/Study Population: A rapid review was performed in February 2024 across 5 databases: PubMed, Scopus, CINAHL, PsycINFO, and PEDRO (PROSPERO 2024 CRD42024516250). A search strategy combined all possible terms and MESH terms related to the population of interest: children or adolescents with CHD and the outcome of interest: PA levels. Descriptive analysis and concept maps were used to further describe the various barriers and facilitators to PA. Results/Anticipated Results: We identified 49 articles. Most articles were quantitative (76%) and assessed demographic influences, such as age and gender. Self-efficacy was the most common facilitator to PA, in addition to wanting to fit in and have fun. Self-imposed limitations and self-perceived barriers such as fears and anxiety, feelings of inadequacy, and lack of enjoyment were barriers to PA. Parents, teachers, and peers facilitated PA by providing support, possessing knowledge about the importance of PA, and by engaging in the activity with the child; however, these groups limited PA by showing anxiety and stress. Barriers related to social determinants of health (SDOH) include costs, lack of education, and accommodations during PA. Environmental barriers included less PA during winter, weekends, and between the hours of 15:00 and 17:00. Discussion/Significance of Impact: Identifying barriers and facilitators to PA in patients with CHD is necessary to design tailored programs that will increase PA behaviors. Future work should integrate perspectives of clinicians, patients, and families with the factors described in this review, to create programs that effectively address low PA levels in the young CHD population.

OBJECTIVES/GOALS: Determine the exosome mitochondrial DNA (mtDNA) copy number in cerebrospinal fluid (CSF) as a measure of neuronal mitochondrial integrity in patients with subarachnoid hemorrhage (SAH). Determine the patterns of beta amyloid and tau protein biology in CSF of SAH patients and correlate those measures with the clinical status of the SAH patients. METHODS/STUDY POPULATION: The CSF is collected from SAH patients undergoing ventriculostomy-based continuous CSF drainage. Adults from all ethnicities and sex are included in this study. The exosomes are isolated from CSF samples using a precipitation method and particle count and size are measured using NanoSight. The DNA is extracted using an exosomal DNA isolation kit (XCF kit). The CSF mtDNA copy number is measured using digital drop PCR with mitochondrial DNA primers. The levels of beta-amyloid (a-beta-40 and -42) and tau protein in CSF are measured using a sensitive ELISA-based assay. A quantitative evaluation of mitochondrial DNA copy number, clinical status of the SAH patients and beta amyloid, and tau protein levels will be conducted and reported. RESULTS/ANTICIPATED RESULTS: Preliminary results of four CSF samples showed similar patterns in CSF exosome particle number, particle size and exosomal mtDNA copy number in relation to samples from the admission day. Particle number decreased with time while particle size increased. More patient samples will be analyzed to confirm the patterns. We anticipate that mtDNA copy number will correlate with brain beta-amyloid and tau protein levels. Moreover, we anticipate that the clinical status of the SAH patients will associate with the mtDNA copy number. We specifically predict that higher mtDNA copy number levels will correlate with better clinical outcomes. DISCUSSION/SIGNIFICANCE: Mitochondrial function is critical to brain health, but we lack effective ways to monitor this parameter. Here we focus on a CSF based biomarker, exosome-derived mtDNA, which is intended to reflect the integrity of brain mitochondria. As bioenergetic metabolism influences beta amyloid and tau biology, predicting those levels are important.

OBJECTIVES/GOALS: The goal of this study is to describe the implementation of a formal research mentoring training program at Miami CTSI in collaboration with University of Colorado CTSI, to build effective mentor-mentee relationships that help build successful research careers for junior faculty. METHODS/STUDY POPULATION: The Miami CTSI Research Mentoring Training is a three-part series for early stage faculty and their mentors to strengthen mentoring skills and build successful relationships. The curriculum uses evidence-based strategies and is modeled after University of Colorado CTSIs CO-Mentor Training Program. The pilot training was conducted as a train-the-trainer program with subsequent workshops led by Miami CTSI faculty. The program has mentee-only, mentor-only, and joint sessions covering topics such as networking skills, managing financial aspects of an academic career, and career mapping. To assess program effectiveness, pre/post surveys were conducted and follow up surveys are planned. Data collected will assess participant diversity, research productivity, and mentoring relationship status. RESULTS/ANTICIPATED RESULTS: A total of 49 mentor-mentee teams from 18 departments participated in the training over two cohorts. An upcoming third cohort will be included in the analysis. Overall, 100% mentors and 86% mentees reported the overall value of the program as positive. Post-training, mentees reported an increase in confidence in creating career development plans and articulating career goals. Mentors reported an increase in confidence in providing guidance tailored to mentees needs. Mentees reported improvement in their knowledge of developing personal narratives and handling financial aspects of research; both mentors and mentees reported improvement in insights into achieving work-life balance. Follow up survey results will provide insight into the evolution of the mentoring relationships. DISCUSSION/SIGNIFICANCE: Miami CTSIs mentoring training demonstrated successful participation and positive feedback from mentors and mentees and is poised to become a critical component of the Miami CTSIs research career development pipeline.

Objectives/Goals: The CHIRP program aims to promote community-driven research on local health priorities, strengthen community–academic partnerships, and build capacity for sustainable and fair research through education, training, and mentoring, while supporting CTSA’s mission to advance translational science. Methods/Study Population: CHIRP, funded by NCATS/CCTS, supports community/academic partnered teams to conduct impactful research in community or clinical settings. Selected projects have undergone a competitive application process: eligibility screening by the CHIRP team, a panel review by both community and academic partners, and scoring using a 9-point NIH system. After final approval by CCTS leadership, selected teams consisting of at least one community partner and one academic partner participate in a mandatory 2-day Proposal Development Retreat where they receive training and resources to further refine their proposal. Upon IRB approval, teams receive funding of up to $20,000 and mentorship from experts during the grant period to support implementation of the proposed project. Results/Anticipated Results: Since its inception, CHIRP has funded 20 academic teams in 3 CTSA regions of Texas (Houston, Northeast Texas, and Rio Grande Valley) in partnership with 20 community organizations such as public schools, faith-based organizations, and community-based health provider organizations, providing $380,000 funding for clinical research or initiatives on health promotion and disease prevention strategies driven by community need. The program resulted in 10 peer-reviewed articles, 15 conference presentations, and multiple community forums. Currently, CHIRP is supporting its fifth cohort of fellows who completed the Proposal Development Retreat and a majority reported being “Very Satisfied” with the training. Discussion/Significance of Impact: The CHIRP model supports community–academic partnerships to drive translational research. The model has application for other sites wanting to train and support community-engaged research and strengthen the translational research pipeline.

OBJECTIVES/GOALS: Nearly all thoracic aortic aneurysm patients suffer from hypertension leading to elevated wall tension and abnormal extracellular matrix remodeling. PTSD patients have higher blood pressure both at rest and in response to stimuli. Although stress is associated with cardiovascular disease, the exact mechanism linking the two is still unknown. METHODS/STUDY POPULATION: Adult C57BL/6 mice underwent a PTSD induction protocol consisting of inescapable foot shock followed by single prolonged stress. The mice were assessed incrementally for their PTSD-like phenotype using specific behavioral tests chosen to assess for each of the human criteria of PTSD according to the DSM-V. Tail cuff blood pressure measurements were taken serially throughout the 16-week protocol. At terminal study, thoracic aortic diameter measurements were obtained through digital microscopy and plasma was harvested for cytokine analysis. Thoracic aortic aneurysms (TAA) were induced through periadventitial application of a calcium chloride solution on the descending thoracic aorta in BPH/2J and BPN/3J adult mice. The thoracic aortic diameter was measured at terminal study through digital microscopy. RESULTS/ANTICIPATED RESULTS: Using our PTSD-like mouse model we have demonstrated that PTSD-like mice have significantly higher systolic blood pressure following a reminder of the traumatic event than control mice recapitulating the human phenotype. They also had increased plasma proinflammatory cytokines and larger thoracic aortic diameters than control mice. Although the increased thoracic aortic diameter is not an aneurysm, it suggests ECM remodeling is occurring predisposing the aorta to aneurysm formation. Finally, we have shown that in neurogenic hypertensive mice, TAA formation was accelerated by 12 weeks with roughly 70% dilation at 4 weeks post-TAA induction surgery as compared to roughly a 20% dilation in control mice. DISCUSSION/SIGNIFICANCE: Altogether, these studies reinforce the link between stress and TAA development, and our mouse model will allow for the underlying mechanism to be elucidated. Better understanding of the mechanism linking PTSD and TAA will allow for the creation of novel therapeutics to treat PTSD symptoms while also delaying TAA progression.

OBJECTIVES/SPECIFIC AIMS: The overall objective of this study is to develop a novel, clinically-relevant, image-guided mouse model for radiation-induced cardiotoxicity, which can be used to gain insight into clinically-targetable, pathophysiologic mechanisms of cardiac injury in thoracic radiotherapy patients. METHODS/STUDY POPULATION: Photon or sham radiation will be administered at differential doses to a defined portion of the heart and/or lungs of C57BL/6 female mice using micro-CT visualization of the heart with Xstrahl’s MuriSlice Software applied to the Small Animal Radiation Research Platform (SARRP). Cardiac and lung segments from a subset of mice will be harvested at specific time points for confirmation of radiation targeting, local apoptosis assessment, and evaluation of fibrosis and vascular tissue morphology. Quantitative echocardiography, myocardial 18F-fluorodeoxyglucose positron emission tomography computed tomography (18F-FDG PET/CT), and myocardial perfusion imaging (MPI) with Technicium-99 (Tc-99) sestamibi will be implemented to identify sensitive imaging measures of cardiac injury and asses myocardial mechanics, inflammation, and perfusion deficits, respectively. Concurrently, a multiparametric analysis will be conducted to identify novel, circulating biomarkers of cardiotoxicity. RESULTS/ANTICIPATED RESULTS: We hypothesize that a clinically-relevant mouse model can be generated by the in situ, focal irradiation of a portion of heart and/or lung tissue segments, and can be used to elucidate molecular mechanisms of radiation-induced cardiac damage. We anticipate time-dependent and dose-dependent, focal histopathologic changes in the mouse heart, with cardiac fibrosis development, vascular damage, and cellular apoptosis in irradiated mice. Additionally, we anticipate that our mouse model of focal heart irradiation will reveal radiologic and biochemical changes that can be used to characterize and predict radiation-induced cardiac injury. Specifically, we expect our quantitative echocardiography, FDG-PET, and MPI parameters to identify and characterize cardiac damage that topographically matches histopathological analysis, and expect levels of select biochemical markers to differentially vary with time. DISCUSSION/SIGNIFICANCE OF IMPACT: Our mouse model of radiation-induced cardiotoxicity has the potential to shift current preclinical research paradigms to more closely mimic the radiation plans most commonly administered in clinical practice. The primary technologic innovation to be developed here is the use of the SARRP to deliver image-guided, in situ, focal radiation to a defined portion of the mouse heart. From a conceptual perspective, we propose a novel approach for phenotyping radiation-induced cardiac damage in patients undergoing chest radiation therapy, integrating sensitive radiomic and biochemical markers into a predictive model of cardiotoxicity.

ABSTRACT IMPACT: The key to advancing precision medicine is to deepen our understanding of drug modes-of-action (MOA). This project aims to develop a novel method for predicting MOA of potential drug compounds, providing an experimental and computational platform for more efficient drug discovery. OBJECTIVES/GOALS: To develop (1) a targeted CRISPR-Cas9 chemical-genetic screen approach, and (2) a computational method to predict drug mode-of-action from chemical-genetic interaction profiles. METHODS/STUDY POPULATION: Screening drugs against a gene deletion library can identify knockouts that modulate drug sensitivity. These chemical-genetic interaction (CGI) screens can be performed in human cell lines using a pooled lentiviral CRISPR-Cas9 approach to assess drug sensitivity/resistance of single-gene knockouts across the human genome. A targeted, rather than genome-wide, library can enable scaling these screens across many drugs.

CGI profiles can be derived from phenotypic screen readouts. These profiles are analogous to genetic interaction (GI) profiles, which represent sensitivity/resistance of gene knockouts to a second gene knockout rather than a drug. To computationally predict a drug’s genetic target, we leverage the property that a drug’s CGI profile will be similar to its target’s GI profile. RESULTS/ANTICIPATED RESULTS: Five proof-of-principle screens will be conducted with compounds that have existing genome-wide profiles and well-characterized MOA. I will generate CGI profiles for these five compounds and identify genes that are drug-sensitizers or drug-suppressors. I will then evaluate whether targeted library screens can recapitulate the CGIs found in genome-wide screens. Finally, I will develop a computational tool to integrate these CGI profiles with GI profiles (derived from another project) to predict gene-level and bioprocess-level drug targets. These predictions (from both targeted and genome-wide profiles) will be benchmarked against a drug-target and drug-bioprocess standard. DISCUSSION/SIGNIFICANCE OF FINDINGS: This work will develop a scalable, targeted chemical-genetic screen approach to discovering how putative therapeutics work. The targeted screen workflow provides a method for higher-throughput drug screening. The computational pipeline provides a powerful tool for exploring the MOA of uncharacterized drugs or repurposing FDA-approved drugs.

OBJECTIVES/SPECIFIC AIMS: Aim 1: To compare frozen MOM to fresh MOM over time as an agent to inoculate DHM and measure the enrichment of commensal microbes and their beneficial bioactive components similar to MOM. Hypothesis: Frozen or fresh MOM inoculated in DHM will produce similar microbial content to MOM over time allowing for the production of beneficial bacterial compounds that may contribute to host immune response. Aim 2: To determine the effect of MOM storage (fresh vs frozen) on the expansion of bioactive components from live microbiota in DHM. Hypothesis: Both fresh and frozen MOM will produce similar results when inoculated into DHM to restore the microbial content (including their bioactive components) similar to each MOM sample. Aim 3: To compare the microbiome found in a mother’s MOM to the microbiome in her infant’s stool. Hypothesis: The mother/infant pair will share a common microbiome between the mother’s MOM and her infant’s stool. METHODS/STUDY POPULATION: Subjects will include 12 pump-dependent mothers of infants born < 34 weeks gestation admitted to the University of Florida Health Shands Hospital, Neonatal Intensive Care Unit (NICU). Inclusion criteria consists of mothers expressing over 100 ml of MOM per day, producing at least 45 ml of MOM at an expression session, at least 18 years of age, and speak English. Mothers are excluded if they have taken antibiotics within 3 days of sample collection, are HIV+, or delivered an infant who has a chromosomal abnormality or is severely ill. An expressed MOM sample will be collected and divided into two fractions: (A) fresh and (B) frozen at -20C for 24 h. The fresh fraction (A) will be processed immediately while the frozen fraction (B) will be processed after 24 h. Each MOM will be inoculated in DHM at dilutions of 10% and 30% and incubated at different time points: 0 h (T0), 2 h (T2), 4 h (T4) at 37°C. At each time point, total viable cell counts as well as microbiome analysis through 16S ribosomal shotgun sequencing will be performed and compared for differences. Bacteria isolated from each MOM will be saved, identified through 16S ribosomal sequencing and grown in culture for future studies. Fecal samples from each corresponding infant will be collected within 48 h after collection of the MOM sample. Stools will be homogenized and subjected to DNA extraction to perform 16S ribosomal shotgun sequencing. Microbiome analysis will be conducted, compared between fecal samples as well as with the microbiome of the MOM. RESULTS/ANTICIPATED RESULTS: Study is ongoing. We anticipate similar results with fresh or frozen MOM to that of a previous pilot study, where enriched microbiota similar to MOM was found when fresh MOM was inoculated and incubated in DHM. The microbiome analysis of the infant fecal samples may illustrate the influence that the microbiome of the MOM may have on the development of the infants’ gastrointestinal microbiota. DISCUSSION/SIGNIFICANCE OF IMPACT: The purpose of this study is to provide evidence on the ability, timing, and efficacy of inoculating DHM with fresh and frozen MOM. Study results will inform future studies to support the implementation of an inoculation procedural protocol to be used in clinical practice and human milk banking. The description of the MOM microbiome, as well as the gastrointestinal microbiome, will expand scientific knowledge on the role breast milk has on the origins of health and disease.

OBJECTIVES/GOALS: Evaluate the use of IC to improve stroke survivors’ capacity for reactive stepping and adapt their gait cycles in response to a difficult walking environment. We hypothesize that IC will improve stroke survivors’ protective stepping response via improvements in muscle activation and motor learning METHODS/STUDY POPULATION: Stroke survivors have an impaired capacity for protective stepping. Decreased paretic muscle activation results in increased reaction time and reduced force generation. Ischemic conditioning (IC) is a vascular stimulus which improves motor performance in chronic stroke. It is performed by delivering transient, intermittent bouts of ischemia to a limb. It has been demonstrated that IC increases muscle activation post-stroke. 9 chronic stroke survivors completed 3 testing sessions and 7 intervention sessions. Participants walked on an instrumented treadmill and were perturbed unilaterally every step at the waist via a cable pulley system. Kinetic and kinematic data were collected. Step width was measured as the difference in position of the heel markers at the instant of heel strike in the frontal plane. RESULTS/ANTICIPATED RESULTS: After one and seven sessions of IC, controls did not alter their responses from baseline testing, but stroke survivors increased their step width by an average of 15% and 23% respectively. DISCUSSION/SIGNIFICANCE: Ischemic conditioning may be a useful intervention to improve stroke survivors’ ability to adapt their paretic foot placement in response to lateral perturbations during gait. Interventions which optimize muscle activation and neural adaptation could significantly improve balance post-stroke.

OBJECTIVES/GOALS: Mammals require iron for hemoglobin, respiration, immunity and as cofactor in enzymes. But free iron is toxic from the production of reactive oxygen species. Ferroportin is the sole exporter of cellular iron and it crucially determines cellular and systemic iron levels. Labile iron must be tightly regulated. This requires structural understanding. METHODS/STUDY POPULATION: We built structure of human ferroportin (FPN1) using the ab ignition prediction approaches of Rosetta/Robetta and by comparative modeling with distance restraints in MODELLER. Templates selected were from solute carrier protein families of distantly related orthologs and homologs including a proton coupled peptide transporter (PDB ID: 4IKV) and the bacterial iron transporter in outward-open and inward-open states, (PDB ID: 5AYM, 5AYO). Each model was validated by experimental mass spectrometry data. The energy minimized structural model was inserted into a lipid bilayer, placed in a rectangular simulation box, covered with TIP3P water solvent balanced with counterions and conditioned. Finally, we carried out 350 nanoseconds molecular dynamics simulations. RESULTS/ANTICIPATED RESULTS: Our first model of FPN1 (571aa), using Rosetta/Robetta ab initio approach, resembles the structure of the proton-dependent transporter, POT and consists of 12 transmembrane helices. The membrane spanning helices veer away from the orientation in the structure of 4IKV. The alternate model using MODELLER and the method of satisfaction of constraints, returned one template, the structure of Bdellovibrio bacteriovorus iron (Fe2+) transporter homolog (5AYN, 440aa) with sequence identity of 19%. Aligning FPN1 on the template sequence incorporating structural information revealed better conservation (29%). This model also comprises 12 transmembrane helices in two bundles separated by a large intracellular loop. The iron binding site predicted in both models match the structures of distant bacterial homologs. DISCUSSION/SIGNIFICANCE OF IMPACT: We are using these experimentally verified structures and functional data to answer questions about the mechanism of ferroportin iron transport, structural dynamics and the significance of mutations in ferroportin seen in different populations, especially the Q248H mutation found in Africans and black Americans with moderate to high prevalence.

OBJECTIVES/GOALS: Targeting the V-domain immunoglobulin suppressor of T cell activation (VISTA) signaling pathway has been suggested as a promising approach for overcoming resistance to current immune checkpoint therapies in advanced cancer. This review will synthesize the rapidly-expanding literature on VISTA protein expression on prognosis in various cancers. METHODS/STUDY POPULATION: To determine the prognostic significance of high VISTA expression across treatment-naïve malignant tumors, a systematic review and meta-analysis will be performed of published cohort studies which measured VISTA protein expression on solid tumors. Primary and secondary outcome endpoints of overall survival (OS) and disease-specific survival (DSS) will be compared across cohort studies using a random effects model to calculate pooled hazard ratios (HRs) for each time-to-event end point with 95% CIs. For articles that only provide Kaplan-Meier (KM) curves, the Engauge Digitizer software will be used to measure the time and survival probability coordinates on the KM curves to estimate the HRs. Correlations of VISTA expression and clinicopathological characteristics will be evaluated by pooled risk ratios. RESULTS/ANTICIPATED RESULTS: A search of 4 electronic databases including Pubmed, Embase, Web of Science and Cochrane resulted in 5578 publications of which 66 containing a broad spectrum of malignant solid tumors will undergo full-text review for study inclusion. Tumor types most represented with at least 3 articles include lung, pancreas, skin, head & neck, colorectal, mesothelioma, cervix, soft tissue, breast, liver and ovarian. Our working hypothesis is that the pooled HR for high VISTA expression on overall survival will be approaching 1.0 given conflicting reports across the cancer literature. Risk of bias will be assessed across studies. Quantifications of heterogeneity will be assessed by visual exploration of forest plots as well as by multiple statistical metrics including the Q statistic and the I²coefficient. DISCUSSION/SIGNIFICANCE: The results of this systematic review and meta-analysis will provide a more comprehensive understanding of VISTA’s prognostic role both across all malignant tumors and for subgroups of similar tumor types which may impact the types of tumors and tumor microenvironments selected for early trials of anti-VISTA therapy.

Objectives/Goals: Although parental ethnic-racial socialization (ERS) supports positive mental health outcomes, existing literature often treats Black identity as monolithic and rarely considers variation across ethnic backgrounds. This study examines differences in ERS messages shared by African American and Somali families. Methods/Study Population: Three dyadic focus groups were conducted between June and August 2025, including a total of 15 (8 Somali and 7 African American) parents and 14 (7 Somali and 7 African American) youth (N=29). Parents and youth participated in separate, semi-structured discussions guided by a parallel script covering five domains: identity and family, racial socialization messaging, context and frequency of conversations, the perceived usefulness of messages, and responses to racialized experiences. Sessions, which lasted 60 to 90 minutes, were audio-recorded, transcribed verbatim, and analyzed in NVivo using a collaboratively developed codebook. Descriptive counts of message endorsement were also calculated to identify patterns in messaging across dyads. Results/Anticipated Results: Participants shared a complex understanding of race and racism, often acknowledging that race “shouldn’t matter, but does,” and describing discrimination as a normalized part of daily life. Parents emphasized that racist moments require a response, while youth described a range of reactions, including anticipation, humor, resistance, and disengagement, often adapting strategies to specific contexts. Across dyads, anticipation emerged as a dominant coping mechanism, with youth preparing mentally and emotionally for potential racial bias. Social media and humor were commonly used for processing experiences, while parents often encouraged measured resistance or dialog over avoidance or physical confrontation. Discussion/Significance of Impact: This study, by examining differences in racial socialization messages across Black ethnic subgroups, can easily identify novel intervention routes that may have been overlooked. Existing racial socialization mental health programs can be expanded and adapted to incorporate the unique messaging or values identified by these different groups.

The α-synuclein seed amplification assay (SAA) is a biomarker for Parkinson’s disease (PD) but requires cerebrospinal fluid. We applied a validated model to predict α-synuclein SAA+ using remotely collected data in LRRK2 G2019S carriers. VALOR-PD participants completed at-home olfactory and autonomic assessments. SAA+ probabilities for manifest and non-manifest carriers at baseline and month 36 visits were estimated. Baseline SAA+ mean probability was 0.57 (manifest) and 0.28 (non-manifest). Over three years, SAA+ mean probabilities increased in manifest (0.66, p = 0.014) and non-manifest carriers (0.38, p < 0.001), paralleling olfactory declines. Remotely collected data may be used to approximate SAA classification.

Recent reports on the burden of cardiovascular disease (CVD) in the USA indicate that despite significant declines in CVD mortality in the late 20th century, this decline is now decelerating and may be worsened by inequalities in health care. Social factors contribute to most of the cardiovascular health disparities documented to date. Hispanics/Latinos and African-Americans share a higher prevalence of cardiovascular risk factors and experience higher rates of poverty and social stressors than non-Hispanic Whites. We propose that the use of social and behavioral data beyond basic and sometimes loose identifiers of race/ethnicity, educational attainment, and occupation would inform clinical practice and greatly facilitate the provision of adequate guidance and support to patients regarding continuity of care, adherence to medications and treatment plans, and engagement of participants in future research. This perspective briefly highlights factors deemed to be critical for the advancement of Hispanic/Latino health and delineates pathways toward future applications.

OBJECTIVES/GOALS: The New Jersey Alliance for Clinical & Translational Science conducted an observational study of current clinical research training to establish a comprehensive infrastructure. The goal was to develop a cross training catalogue of available resources for trainees to fill gaps in their Clinical Research training. METHODS/STUDY POPULATION: The focus of this observational study is the evaluation of (1) available clinical research training programs, (2) training areas aligned with the Joint Task Force competency domains, (3) specific target audiences who utilize trainings offered nationally, and (4) availability of resource toolboxes. This assessment was extracted by clicking on each of the hubs Education & Training and Resources tabs. The determination of the training areas and competency skills that aligned with the JTFs eight domains was confirmed by reviewing the course description on each website. RESULTS/ANTICIPATED RESULTS: CTSA hub website analysis of each hub revealed that each CTSA hub region has their own regional focus on training areas targeted for specific audiences. The validation of the NJ ACTS Education and Offering Inventory study allowed authors to categorize available training programs which significantly showed that Basic Training Programs targeted 22% of Undergraduate Students, Community Engagement Training Programs targeted 15% of Early Career Faculty, Experiential Training targeted 20% of Early Career Faculty and Undergraduate Students, Scholarly & Certificate Training targeted 20.5% of Graduate Students, and Graduate/Post Graduate Programs targeted 22.5% of Graduate Students and KL2 scholars. DISCUSSION/SIGNIFICANCE: This information helps build the infrastructure of a National Cross-Training Resource Platform in aid to encourage trainees to take advantage of available trainings across the CTSA Consortium.
