Team science is central to clinical and translational research; however, systematic evaluation of collaborative efforts remains inconsistent and underdeveloped. To better understand current team science evaluation practices within clinical and translational science programs, we conducted a structured cross-sectional survey of team science and evaluation professionals. We analyzed quantitative data using descriptive statistics and qualitative responses through thematic analysis. Among participating organizations, the majority have implemented team science evaluations, predominantly using mixed-methods approaches combining quantitative metrics and qualitative assessments. Evaluation findings were primarily used to inform programing, improve team functioning, and secure funding. Reported challenges fell into four key areas: methodology; implementation; data analysis; and organization. Facilitators included: methodological enhancements, organizational support, collaborative approaches, and infrastructure elements. Participants emphasized using interim measures (e.g., team dynamics and satisfaction) that move beyond traditional outcome measures so that evaluations better reflect how teams interact, adapt, and progress as they develop. While team science evaluation adoption is substantial among leading translational research institutions, significant methodological gaps persist. Future directions focus on developing standardized frameworks with local flexibility, creating validated instruments, utilizing interim process measures, and demonstrating return on investment (ROI) to advance both evaluation science and translational outcomes.

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

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

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

OBJECTIVES/SPECIFIC AIMS: Ivor-Lewis esophagectomy (ILE) is an invasive surgical procedure with a high incidence of postoperative pneumonia. Antibiotic prophylaxis could reduce respiratory infections but increase Clostridium difficile and antibiotic resistance. Our institution reduced the duration of piperacillin-tazobactam prophylaxis following ILE from 4 to 1 day or less in January 2015. We evaluated short-term outcomes in ILE patients before and after this institutional change. METHODS/STUDY POPULATION: Retrospective cohort study of all ILE patients from 2012 to 2016. We confirmed antibiotic duration directly from nursing medication administration records. The primary outcomes of this study were rates of C. difficile and postoperative pneumonia. Secondary outcomes include other infection, length of hospital stay, and readmission within 30 days. We used logistic regression to analyze impact of days of antibiotics and χ2 or Fischer exact tests for categorical variables. RESULTS/ANTICIPATED RESULTS: Of 104 ILE patients, 40.4% (n=42) were after January 2015, 11.5% developed pneumonia and 5.8% developed C. difficile colitis. ILE patients received more days of antibiotics before the institutional change compared with after (6.1 vs. 2.9 d, p<0.01). For a 1-day increase in antibiotic duration, the odds of acquiring C. difficile increased significantly by 1.2 (p=0.03). Before compared with after the institutional change, rates of C. difficile were 8.1% Versus 2.4% (p>0.2), rates of pneumonia were 11.3% Versus 11.9% (p>0.2), and length of stay was 10.9 Versus 10.5 days (p>0.2), respectively. DISCUSSION/SIGNIFICANCE OF IMPACT: Institutional policy can have an impact on patient outcomes. Antibiotic stewardship is associated with reduced rates of inpatient C. difficile. Our study suggests reduced antibiotics are not associated with pneumonia, although larger studies are necessary to confirm this finding. Surgeons should consider the benefit of decreased rates of C. difficile before administering prolonged antibiotic prophylaxis following esophagectomies.

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

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

Objectives/Goals: The Wake Forest Clinical and Translational Science Institute (WF CTSI) provides resources such as services and tools for investigators. Due to the number of service users over the past six years, it has been a challenge to track usage and impact across the institution. Our goal is to create an internal dashboard to assist with tracking CTSI service usage. Methods/Study Population: The Dissemination, Implementation, and Continuous Quality Improvement (DICQI) team collaborated with members of the Service Programming team to develop an internal dashboard for tracking service usage. Service Programming team members sourced data from multiple systems, including the CTSI Service Request Form, CTSI Metrics Form, Profiles, and program-specific datasets. The PI Dashboard aggregates this data: service request and metrics form data are retrieved via the REDCap API, while publication data are queried from the Profiles database using Python’s pyodbc library. All collected data are parsed and stored in the dashboard’s internal database to support analytics and reporting functions. Results/Anticipated Results: Data pulled from multiple sources were integrated into a centralized internal dashboard for Wake Forest CTSI to review and evaluate metrics data such as service usage, program participation, and training/tool utilization. This CTSI service usage dashboard also was efficient for filtering data by dates, faculty researcher, or CTSI usage rate, which is helpful for reporting and long-term impact evaluation. This internal dashboard now will be integral in not only impact tracking but reporting for grant renewal periods of the Wake Forest CTSI. Discussion/Significance of Impact: A central database enables clear snapshots of WF CTSI impact, supporting long-term goals through strategic decision making, data quality, and collaboration. Understanding the broader impact of our CTSI is important for impact evaluation, reporting, and aligning with academic learning health system goals.

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

OBJECTIVES/GOALS: Disparities persist among minority and marginalized populations in immunizations and research. The Clinical Research Vehicle Team aimed to bring research to our community’s doorstep, building generalizability of research outcomes. Our mission adapted due to the pandemic to include increasing COVID-19 vaccinations and health education. METHODS/STUDY POPULATION: Community Engagement Events are planned when event organizers submit a request, then the proposal is discussed by the Clinical Research Vehicle (CRV) Team and UF HealthStreet. We go to underserved communities throughout Florida, food distributions, churches, community centers, rural areas, etc. At these events we offer services at no cost, including: COVID-19 and flu vaccines, as well as health screenings. We provide health education to individuals and refer them to UF HealthStreet for community resources, as appropriate. Research events are planned when researchers submit a request for the CRV, then the request is discussed by the CRV Team. The studies covered topics from COVID-19 research to the development of a diverse health database. Our fleet consists of two Community Health Vehicles and the CRV. RESULTS/ANTICIPATED RESULTS: As Community Engagement Events are ongoing, the presented numbers are reflective of the data available at the time of submission. Our impact includes administering 1,606+ COVID vaccines, conducting 1,081+ health screenings, collecting data from 944 screenings, providing 265 Flu vaccines, supporting 267+ community health events, and serving 25+ communities. The Clinical Research Vehicle facilitated 6 IRB-approved studies, administration of monoclonal antibody infusions, extended the capabilities of the Clinical Research Center, and enabled clinical trials aimed for novel treatments for COVID-19 positive participants. DISCUSSION/SIGNIFICANCE: Championing this initiative has shown an impact on vaccination rates and health education in communities. Experience and knowledge gained by our team throughout the pandemic while engaging with community members provided a platform from which to build generalizability of research outcomes and support translational science.

OBJECTIVES/GOALS: Hemiplegic cerebral palsy (HCP) limits the functional ability of one side of the body, but motor impairments are very heterogeneous among children with this diagnosis. The purpose of this study was to evaluate the CST using DTI and tractography analyses as it relates to quantitative measures of the severity of weakness and mirror movements in HCP. METHODS/STUDY POPULATION: Preliminary results include five participants with HCP (2M, 16±7.8 years) and six controls (2M, 12±3.5 years). DTI data were collected using a spin-echo echo-planar imaging sequence with diffusion weighting of b=1000 s/mm2 in 60 different directions and 8 scans without diffusion weighting (b=0 s/mm2). Images were processed with steps of brain extraction, denoising, motion and eddy current correction, and fit with tensors to generate maps of diffusivity metrics. Anatomical landmarks were used to guide probabilistic tractography of the CST for analyses in both the lesioned and non-lesioned hemispheres. To quantify grasp weakness and mirroring severity, participants completed a bilateral assessment of grip strength using handheld force measurement devices and custom MATLAB data acquisition software. RESULTS/ANTICIPATED RESULTS: DTI is a feasible method to evaluate CST microstructure in HCP and typically developing pediatric participants. Spearman correlation analyses, using age and sex as covariates, revealed that for the lesioned hemisphere CST, there were significant positive correlations between grasp weakness severity and mean diffusivity (MD) (Ï=0.66, p=0.038) and between grasp weakness severity and axial diffusivity (AD) (Ï =0.68, p=0.030). There was not a significant correlation between grasp weakness severity and fractional anisotropy (FA) (Ï =-0.47, p=0.166). For the non-lesioned hemisphere CST, there was a significant positive correlation between mirroring severity and radial diffusivity (RD) (Ï =0.70, p=0.023). There was not a significant correlation between mirror movement severity and FA (Ï =-0.41, p=0.2361). DISCUSSION/SIGNIFICANCE: The correlations demonstrated here show a potential relationship between CST microstructure and the severity of hand impairments in HCP. While these relationships between CST diffusivity properties and hand function are preliminary, they provide the first steps to better understand underlying neural mechanisms for motor impairments in HCP.

OBJECTIVES/GOALS: Data were collected or abstracted from a wide variety of sources related to health and health care needs to determine the current health status of the Galveston community including:

• Demographics

• Social Determinants of Health

• Health Care Access and Insurance Status

• Poverty and Socio-Economic Indicators Impacting Health

• Health Behaviors

• Chronic Disease

• Communicable Disease

• Birth Outcomes

• Mortality

• Cancer

• Data on Services Provided at UTMB

• Data on Services Provided through the Galveston County Health District

• Data on Services Provided through the St. Vincent’s House Clinics, student-led clinics operated at a local non-profit organization

• Previous Galveston County Community Health Needs Assessment

• Identifying Gaps in Services

• Prevention Quality Indicator Data

METHODS/STUDY POPULATION: In addition to collection and analysis of secondary data, we also interviewed key stakeholders to solicit their input and recommendations. We met with leadership from St. Vincent’s House regarding current services provided, perceived issues and concerns, and needs for improvements. We met with leaders from UTMB’s academic enterprise to discuss the operation of our current student-led clinics as well as ways in which clinical practice experiences might be expanded and included more formally in the student curricula should the clinical capacity of St. Vincent’s House also be significantly expanded. This would increase the number of services that could be offered at St. Vincent’s and greatly increase the capacity for enrolling patients without relying on faculty volunteers to staff the clinics. We also met with UTMB leaders in a position to provide insight to issues that bridge the UTMB practice arena and public health and with Community Health leaders from the Galveston County Health District and Teen Health Clinics. Information Services leadership and Institute for Translational Science informatics faculty and staff were instrumental in determining what data could be abstracted from the Electronic Medical Record (without patient identifiers) to determine the specific need for services at St. Vincent’s. RESULTS/ANTICIPATED RESULTS: The City of Galveston has a population just under 50,000. Since 2010, the proportion of elderly has increased, and the proportion of families with younger children has decreased. Poverty is high at 22.3% for all people, and especially high for children at 32.1%. Poverty disproportionately affects racial and ethnic minorities, with 36.5% of the Black population living below the poverty level, compared to 25.5% Hispanic, 30.5% Asian, and 14.7% White. Home ownership is decreasing, and median rent costs have sharply increased. The percentage without health insurance is considerable, driven by educational attainment, age, and race. In 2017, >40% of renters spent more than 35% of their income on housing. Upwards of 2,650 reported not having access to a vehicle for transportation. While residents of Galveston County as a whole are less impoverished, those that are impoverished share marked similarities. Lower educational attainment, in particular failure to complete high school or obtain a college degree, are correlated with race. Lower educational attainment then is highly predictive of poverty and low income. The income inequality ratio, i.e., the greater division between the top and bottom ends of the income spectrum in Galveston County is higher than in Texas or the nation and has increased every year but one since 2010. Issues of concern for Galveston County include obesity, Type II diabetes, and disability. These are exacerbated by built and social environment issues such as food insecurity, limited access to healthy foods, and food deserts in some neighborhoods. Pre-term birth rates are higher in Galveston than in the state or nation, and approximately 40% of women do not receive prenatal care until the 2nd or 3rd trimester or receive no prenatal care at all. 8.4% of births are low-birth weight. Marked disparities by race and ethnicity exist for each of these indicators. Age-adjusted death rates for all-cause mortality are higher in Galveston County than they are in Texas or the United States. Perhaps of most concern are the rates of death from septicemia, which are nearly triple that of the U.S. and nearly double that of the state, and cancer. Cancer incidence is not particularly remarkable, however, cancer age-adjusted mortality rates for many specific cancers well exceed state rates. DISCUSSION/SIGNIFICANCE OF IMPACT: With a clearer picture of the medical and other needs impacting health or health care access for our community, all stakeholders and experts can provide more detailed recommendations about prioritizing care and especially, preventive care—much of which could conceivably be provided in St. Vincent’s House clinics. Opportunities exist for enhanced practice and education opportunities for UTMB students from all schools. Preventive Care and Population Health practices can be brought to bear in novel practice settings that could serve as models for provision of integrated services. Social and other services provided by non-profit organizations can be coordinated and streamlined. It is our hope that the considerable data presented herein will enable stakeholders to begin to prioritize issues and to make some evidence-based decisions about the next steps in this process. Throughout the interview and data collection process, all stakeholders have expressed both enthusiasm and hope at the prospect of re-visioning how they can contribute to a process that will improve how we as a community care for our most vulnerable members. CONFLICT OF INTEREST DESCRIPTION: The authors have no conflicts of interest to disclose.

Objectives/Goals: Summarize literature on parenting stress and treatment outcomes among postpartum women with opioid use disorder (OUD). Describe the causes of parenting stress identified by postpartum women who received medication for OUD (MOUD) and service providers. Discuss recommendations for parenting support services for postpartum women receiving MOUD in outpatient treatment settings. Methods/Study Population: We will conduct focus groups with postpartum women who received MOUD up to one-year after childbirth (2 groups; n  =  10) and service providers (e.g., obstetrics, psychiatry, pediatrics, primary care; 2 groups; n  =  10) to identify causes of and contributors to parenting stress to inform the adaptation of a parenting intervention for postpartum women receiving MOUD in an outpatient clinic setting. Participants will be recruited via flyers, email, and social media reach-outs, clinic staff and patient group meetings, and community-based outreach methods. Participants will be compensated for their participation. Focus groups will be audio-recorded and transcribed. Data will be analyzed via rapid analytic procedures using a summary template matrix. Results/Anticipated Results: We will use parenting-related stressors identified by mothers with substance use disorders in previous research to guide our interview questions. We expect to hear participants speak about their knowledge and experiences with stigma, guilt and shame, mental health symptoms, neonatal opioid withdrawal or neonatal opioid withdrawal syndrome (NOWS), fear of being reported to child protective services, and difficulties with mother–infant bonding and attachment. We will also ask participants about structural barriers that are known to increase parenting stress, such as housing instability, financial strain, and availability and cost of childcare. We will also report on new themes that emerge from the data that are shown to increase stress, challenge sobriety, and hinder continued engagement in the treatment. Discussion/Significance of Impact: Discontinuation of MOUD in the postpartum period is high and can lead to opioid recurrence and overdose. Outpatient treatment programs who offer psychiatric and behavioral health care, and parenting programs that target contributors of early postpartum parenting stress could improve health and MOUD treatment outcomes for mothers with OUD.

Objectives/Goals: Six CTSA hubs collected Translational Science Benefits (TSBM) Model data and implemented standardized coding to enhance rigor and reproducibility, assess the real-world impact of CTSA-supported research, and analyze cross-institutional impact trends. Methods/Study Population: Six CTSA hubs surveyed supported investigators who self-reported the TSBM benefits resulting from hub-supported project(s). De-identified data was shared with the University of California (UCI) CTSA. UCI coordinated with hubs to code their own data using a TSBM coding tool to assess which applicable criteria were met. UCI collected feedback on usability and facilitated discussions to enhance reliability across coders. UCI provided final datasets to hubs for site-specific analysis of benefits and conducted cross-site analyses of TSBM benefits. A benefit was demonstrated when 2 necessary criteria were met, and 80% of the possible criteria were met. Results/Anticipated Results: TSBM data were coded by 6 CTSA hubs from 86 pilot research projects. Most pilots were funded for 1 year (80%) with the mean award over $41,000. Investigators for projects were surveyed up to 7.5 years post-award, with the median timepoint around 3 years. Across hubs, 274 potential benefits were reported and 34 demonstrated benefits were confirmed from coding. Pilots more commonly had demonstrated clinical and medical benefits (16.3% of projects) than community (5.8%) or economic (3.5%). No projects had demonstrated policy benefits. Over 24% of projects had one or more demonstrated benefit of any kind. Demonstrated benefits were reported in 27.8% of projects surveyed within 2.5 years, 18.2% of projects from 2.5 to 5 years, and 50% of projects over 5 years post award. Discussion/Significance of Impact: A standardized, reliable coding process for TSBM data creates rigor for assessing real-world impact data that hubs can confidently connect to their support of CTSA funded-projects. This shared methodology across hubs allows for cross-institutional impact analysis and dissemination.

Objectives/Goals: Using k-means clustering, we aimed to identify whether clusters characterized by greater exposure to minority stressors (e.g., experienced/anticipated discrimination) were associated with lower moderate-vigorous physical activity (MVPA) and higher sedentary behavior among sexual and gender minority (SGM; e.g., lesbian/gay, bisexual, transgender) adults. Methods/Study Population: SGM adults face higher risks of inadequate PA due to exposure to minority stressors, which may influence their willingness and ability to engage in PA. An online sample of SGM adults completed daily surveys about experienced and anticipated discrimination and wore wrist accelerometers for 28 days to objectively measure PA. We used k-means clustering to identify clusters based on reports of experienced and anticipated discrimination. We determined the optimal number of clusters using established partition criteria and ran linear regression models (adjusted for demographic factors) to examine the associations of minority stress clusters with MVPA and sedentary time. Results/Anticipated Results: Among 42 SGM adults (mean age 27.0±7.7 years) with 1133 person-days of accelerometry data, we identified four minority stress clusters: low anticipated/low experienced (LALE; reference group), low anticipated/high experienced (LAHE); high anticipated/low experienced (HALE), and high anticipated/high experienced discrimination (HAHE). Participants in the HALE cluster (n = 12) engaged in 202 fewer minutes of MVPA than those in the LALE cluster (n = 7). Participants in the LAHE cluster (n = 10) had 123 fewer minutes of vigorous PA than those in the LALE cluster. No differences were identified for sedentary time. Discussion/Significance of Impact: This is the first study to examine the association of minority stressors with objective PA among SGM adults. Participants in the HALE/LAHE clusters had lower PA than those with low levels of experienced and anticipated discrimination. Interventions to improve PA among SGM adults must target reduction of minority stressors.

OBJECTIVES/SPECIFIC AIMS: Dissemination of research findings through the published literature is a complex but critical part of the scholarly communication process. Additionally, this time point on the translational spectrum is a key objective of the National Clinical Association for Advancing Translational Sciences (NCATS). Tracking the dissemination of research outputs can be difficult to identify and evaluate. The purpose of this case study was 2-fold: (1) identify tools and resources available freely to the public and through university subscriptions used to assess research output; and (2) compare the effectiveness of these tools oat tracking output at different levels of granularity. METHODS/STUDY POPULATION: The authors, Spectrum staff (D.A.) and School of Medicine librarian (M.B.), attended webinars hosted by other Academic Medical Center libraries conducting work on impact tracking and learned from vendor product managers about available tools and resources during on-site campus visits. Publications from Stanford’s Clinical and Translational Science Award (CTSA) were used to track the diffusion of research outputs (e.g., number of citations, document types, research areas, relative citation ratio, CTSAs collaboration) via library subscription services (e.g., Web of Science and Scopus) and freely available tools (e.g., iCite and PubMed). RESULTS/ANTICIPATED RESULTS: The authors found certain tools were more inclusive in retrieving grant funded research outputs. For example, in the case of UL1 grant (UL1TR001085, UL1TR000093, UL1RR025744), on a grant-level output, there were discrepancies in the number of publications retrieved: (1) PubMed found 644 outputs; (2) Web of Science found 497 outputs; and (3) Scopus found 190 outputs. After de-duplication, the search across Web of Science (WoS), Scopus, and PubMed yielded 899 publications. In total, 389 outputs were unique to PubMed; 165 were unique to WoS; and 90 were unique to Scopus. Future analysis will be conducted to identify the source of unique outputs from each database (e.g., conference proceeding, specific journals). Additional analysis based on other units of research outputs (e.g., author-level outputs and article-level outputs) are expected to yield similar discrepancies. DISCUSSION/SIGNIFICANCE OF IMPACT: Citation analysis is a valuable method of assessing research output and, to a larger extent, research impact in a given field. It can help investigators illustrate qualifications for undertaking new projects, highlight collaborations across schools and departments, justify a grant renewal, and/or highlight accomplishments for promotion. However, systematic and comprehensive evaluations are needed in tandem with citation analysis/bibliometric analysis to assess the translation and uptake of research outputs and activities that result in research impact. Furthermore, both investigators and staff need adequate time and training to process research outputs/activities and to effectively organize them in easily understood visualizations.

OBJECTIVES/GOALS: In this study, the ability of a pathologist to detect malignancy on digital pseudo-H&E slides obtained via structured illumination microscopy (SIM) imaging of fresh diagnostic breast biopsies was assessed. The speed of imaging and processing was also assessed for potential clinical implementation. METHODS/STUDY POPULATION: This study was conducted in accordance with an Ochsner Medical Center of New Orleans IRB. 200 patients undergoing either stereotactic or ultrasound-guided diagnostic breast biopsies were consented and an additional core from the suspicious lesion was collected for research use. Research biopsies were transported to the lab and stained with DRAQ5 and Eosin-Y and imaged with SIM before being submitted for histology processing. Imaging and digital processing times were recorded. The resulting SIM images and histology slides were given to a pathologist for blind review to assess accuracy. RESULTS/ANTICIPATED RESULTS: The ex-vivo structured illumination microscopy images and subsequent histology slides from 79 research cores have been assessed to date. Some samples were excluded from the total data set and not included in the final assessment due to technical failures of the imaging protocol. Of the current set, the pathologist has a specificity of 88% and a sensitivity of 65%, as well as an NPV of 88% and a PPV of 65%. Staining time for each biopsy was completed within 3 and a half minutes and imaging at 20x magnification took between 4 and 12 minutes, depending on size and implementation of autofocus to the imaging system. Image processing took approximately 5 minutes per biopsy and is a direct function of biopsy size. DISCUSSION/SIGNIFICANCE: Decreased time between cancer suspicion and treatment will improve the prognosis of breast cancer patients. SIM imaging of fresh breast biopsies could ultimately allow primary and secondary histology to be performed simultaneously and minimize histopathology time, thus allowing clinicians and patients to implement treatment course more quickly.

OBJECTIVES/SPECIFIC AIMS: To identify factors associated with urban youth and parent perceptions of the preventability (PoP) of the youth’s medically attended assault injuries in order to guide future violence prevention strategies. METHODS/STUDY POPULATION: Assault-injured youth (n=180; ages 10–15; 60% male; 96% African-American) and their parents were recruited from 2 pediatric emergency departments (EDs) in Baltimore and Philadelphia between June 2014 and June 2016. Data on demographics, circumstances of injury, injury severity, and perceptions of the injury were collected from chart review and in-person interviews with youth and parents using previously validated instruments. Within youth and parent groups, we compared those who reported “definitely true” when asked if the event that brought them to the ED could have been prevented to those who reported “maybe true” or “unlikely” using χ2 testing. RESULTS/ANTICIPATED RESULTS: In total, 68 (37.8%) youth and 123 parents (68.3%) reported that the injury was definitely preventable. Youth who were injured indoors [OR 2.13 (95% CI 1.17, 3.88), p=0.013] or considered their injury not serious [OR 4.82 (95% CI 1.78, 13.11), p=0.002] were more likely to perceive injury preventability and those who reported being the victim were less likely to perceive injury preventability [OR 0.26 (95% CI 0.01, 0.67), p=0.005]. Bullying and use of weapons were not associated with youth PoP. Parents were significantly more likely to perceive preventability when the person/people involved were known by the youth [OR 1.94 (95% CI 1.04, 3.62), p=0.037] and when the injury occurred indoors [OR 1.96 (95% CI 1.04, 3.69), p=0.038]. Similar to youth, parental report of bullying was not associated with parent PoP. Injury severity, and victim role of their child were also not associated with parent PoP. DISCUSSION/SIGNIFICANCE OF IMPACT: A prior violent injury is a major risk factor for future injuries and homicides. Through our work we were able to identify factors associated with youth and parent perception of preventability of injuries in a high risk population.
