OBJECTIVES/GOALS: The University of Rochester CTSI Research Education Hub is designed to: 1) connect the local research community with essential internal and external educational resources; 2) create a community of inquiry and collaboration across the translational science workforce pipeline within the university. METHODS/STUDY POPULATION: The Research Education Hub (RE-Hub) utilizes the university’s widely used Learning Management System (LMS), Blackboard, and accessible to anyone at the university with a BlackBoard account. The RE-Hub greets users with an overview, an introduction of key local faculty experts in relevant research methodologies, and links to institutional research programs and helpdesks. Users are provided with curated educational resources organized by topic areas including, but not limited to, research methodology, statistical analysis, and grantsmanship. Discussion boards were created for users to ask general research questions and to connect with others in the translational research community. RESULTS/ANTICIPATED RESULTS: The RE-Hub was designed in Fall 2019 with the purpose of increasing utilization of university resources, including workshops, seminars, methods forums and consultation resources to improve translational science at the university. The RE-Hub was designed to be flexible and responsive to the changing needs of the local research community. User feedback will be used to identify improvements in the organization and content of the RE-Hub. Future improvements will include additional topic areas that span translational competencies, additional materials added to existing topic areas, and facilitation of better collaboration and integration of career development programs and grantsmanship resources. DISCUSSION/SIGNIFICANCE OF IMPACT: The Research Education Hub provides the University of Rochester translational science research community with a space to explore educational resources, to interact with colleagues and ask research related questions, and to help develop and/or improve other educational programs at the university.

OBJECTIVES/GOALS: Medications to treat opioid use disorder (mOUD) are available and can save lives, but are underutilized. We hypothesize that the rate of prescribing varies by treatment facility and these differences will shed light on barriers and facilitators to mOUD utilization. METHODS/STUDY POPULATION: We performed an exploratory analysis in MD Clone, a platform which generates non-identifiable synthesized data based on real patient data in the electronic health record (EHR) of St. Louis based hospitals. Our query included adults aged 18-70 with an OUD diagnosis using ICD-9 of -10 codes (opioid abuse, opioid dependence, opioid poisoning, opioid withdrawal) occurring between 2013 and 2022 along with prescriptions for buprenorphine, methadone, or naloxone within 7 days of the condition being entered in the record. We compared the rate of medication prescription within 7 days across settings and facilities where the patients were seen. We propose to replicate this analysis in actual patient records from the EHR following IRB approval. RESULTS/ANTICIPATED RESULTS: Our synthetic data comprised 24600 patient diagnoses. After filtering for patients seen in the ER or inpatient 16235 patients remained in the data set. Of these, 4376 fell into one of the categories that clearly warrant treatment with medication. Out of 4376 patients with a qualifying OUD related condition, only 815 (18.6%) received a prescription for any of the medications. Rates of prescribing within facilities varied between 67.2% of eligible patients receiving a prescription at a rural location to 0% at some urban centers. We anticipate similar findings from analysis of patient records obtained from the EHR. We will extend our analysis to explore factors which may be driving the wide difference in prescribing to better understand barriers and facilitators to mOUD utilization. DISCUSSION/SIGNIFICANCE: We identify under-utilization with differences across facilities in prescribing mOUD based on preliminary work in synthetic data. If true, this represents a gap in care and opportunity for intervention. By replicating the MD Clone results in patient data from the EHR we will confirm this finding and increase acceptability to clinicians.

OBJECTIVES/SPECIFIC AIMS: A growing concern about the declining physician-scientist workforce prompted the 2014 National Institutes of Health (NIH) Physician Scientist Workforce to recommended that “tools for assessing the strength of the biomedical workforce” be developed. To aid strategic planning, the Oregon Clinical and Translational Research Institute convened key stakeholders at its home university, Oregon Health and Science University (OHSU), to survey the local landscape of physician scientists. Surprisingly, few consensus methods were available to measure and benchmark OHSU with respect to national comparators. To address this deficit, we sought to develop clear and objective metrics describing physician-scientist success at our institution. By focusing on local funding, we were able to generate more complete and robust data than others have reported. These data also permit us to compare ourselves to the national workforce, using well-curated and accessible national databases. The goal of the analyses is to contribute to strategic decision-making by portraying the local physician-scientist workforce, comparing it to the national landscape, and making recommendations about mechanisms to address potential opportunities. This has led us to develop a simple quantitative dashboard, which now permits OHSU to craft strategic targets and address successes and opportunities. These approaches are likely to be valuable elsewhere. METHODS/STUDY POPULATION: OHSU is a medium-sized academic health center in Portland, Oregon with over 1200 principal investigators and over $230M in NIH funding. The primary focus of our investigation was physician-scientists who receive extramural funding. To align with other analyses, we distinguish physician-scientists with an M.D. only, or with an M.D. and a master’s degree, from physician-scientists who hold an M.D./Ph.D. For this distinction, we use the indicator “M.D.-only” to indicate the former. The study design consisted of (a) selection of available and relevant national level data on the physician-scientist workforce, (b) curating of local level data to align it with the national indicators, (c) comparing the 2 sets of data to look for differences in trends over time, and (d) supplementing the analyses with additional local data not available at the national level. Key comparisons were tested for statistical significance and plotted on a dashboard, which was then reviewed by an OHSU internal working group focused on physician-scientists. Data elements included degrees, age, gender, and grants awarded. National data come directly from the NIH Data Book, updated for fiscal year 2016. The NIH makes all funded project data available in the publicly downloadable ExPORTER Data Catalog. These project data were used to supplement the summarized data available from the NIH Data Book, allowing us to extract OHSU investigators and to complete the K to R comparative analysis. For analyses of OHSU investigators holding funding other than RPGs, we relied on institutional data from the OHSU grants and contracts office. Demographic data on OHSU investigators were obtained from departmental and human resource records. The time period for these analyses was 1998–2016. RESULTS/ANTICIPATED RESULTS: At OHSU, as nationally, there has been an increase in RPG-holding Ph.D.s but not in RPG-holding physician-scientists. At OHSU, nearly three-fourth of physician-scientist RPGs hold an M.D.-only degree, compared with nationally, where nearly half of physician-scientists are M.D./Ph.D.s. The percent of younger, early-career, RPG-holding physician-scientists has declined precipitously at OHSU and nationally. At OHSU, the percentage of RPGs held by women physician-scientists is below the national figure. Funding sources for physician-scientists at OHSU were more diverse than for Ph.D. scientists, and physician-scientists comprise the majority of Principal Investigators on clinical trials. These non-RPG sources of funding remain a critical source of support, although local analyses of time spent on research indicate that physician-scientists with NIH funding spend a greater percentage of their time on research than those without. OHSU PI’s have had success in transitioning from K08 and K23 grants to R-level grants, with similar percentages receiving RPGs within 5 years. A dashboard comparing these trends was developed. DISCUSSION/SIGNIFICANCE OF IMPACT: There were 3 key impacts from our analyses. First, we developed and disseminated a dashboard with both local data and national comparators. Second, in consultation with institutional leadership, we selected target values to define success for each metric. Third, we recommended actions that will help OHSU meet the selected targets. A major accomplishment of this structured approach has been the identification of opportunities for change that were not recognized previously. For example, leadership was not aware of the substantial and growing deficit in female physician-scientists at OHSU, compared with the impressive increases nationally. Thus, to reduce gender disparity at OHSU, we have recommended purposeful recruitment; one approach is to target female graduates of Medical Scientist Training Programs for faculty positions, as this group has better success at achieving R-level funding than do M.D.-only applicants. Another outcome is to help set ambitious but reasonable targets for improving the local landscape. Thus, we aim to reduce the average age of RGP-holding physician-scientists at OHSU by one year during the next 5 years. Although reversing current trends will not be easy, our analyses suggest that the average age of RPG level physician-scientists at OHSU would decrease were OHSU were to match the national-level proportions of women and M.D./Ph.D. physician-scientists. In addition to targeting gender disparities, we have recently implemented a program that supplements funding for recruiting young physician scientists, and then supporting their pursuit of RPG funding. Locally, a bright spot is the K to RPG transition rate for K23 awardees, which compare favorably with national data, an outcome that we plan to maintain. In analyzing this area of success, one reason is our strong mentorship program, called OCTRI Scholars, which is provided through our CTSA-sponsored institute. This has fostered an atmosphere of success among young physician-scientists and is one of the reasons that we endorse recommendation #9 from the PSWR, suggesting that Clinical and Translational Science Award (CTSA) Institutes play pivotal roles in monitoring and enhancing the success of the physician-scientist workforce. Thus, several perceived deficiencies might be addressed with adjustment of 1 or 2 specific institutional policies. While the specific opportunities and strengths may be different at other institutions, our proposed dashboard, which couples publicly curated, freely accessible databases, with readily available institutional resources, should help institutions to set and achieve their own goals.

OBJECTIVES/GOALS: #NAME? METHODS/STUDY POPULATION: Cell culture & protein identification: human T cells were purified from healthy blood, then activated & cultured for 5d. CAR-T cells were collected from infusion bags of cancer patients undergoing CAR-T. Silver staining of naive & activated healthy T-cell lysates was compared; B-II spectrin was upregulated and confirmed by Western blot. Migration assays: naive & activated T-cells were imaged during migration on ICAM-1 and ICAM-1 + CXCL12 coated plates. T-cells were transfected with BII-spectrin cDNA & the chemokine dependence of migration was compared with controls. In-vivo studies: in a melanoma mouse model, BII-spectrin transfected or control T-cells were injected; tumors were followed with serial imaging. Human patient records were examined to correlate endogenous BII-spectrin levels and CAR-T response. RESULTS/ANTICIPATED RESULTS: Activated T-cells downregulate the cytoskeletal protein B-II spectrin compared to naive cells, leading to chemokine-independent migration in in vitro assays and off-target trafficking when CAR-T cells are given in vivo. Restoration of B-II spectrin levels via transfection restores chemokine-dependence of activated T-cells. In a mouse melanoma model, control mice injected with standard activated T-cells showed fewer cells in the tumor site and more cells in the off-target organs (spleen, lungs) when compared to mice injected with B-II spectrin transfected cells. Furthermore, among 3 human patients undergoing CAR-T therapy, those with higher endogenous B-II spectrin levels experienced fewer side-effects, measured by the neurotoxicity and cytokine release syndrome grades. DISCUSSION/SIGNIFICANCE: A major hurdle to widespread CAR-T therapy for cancer is significant, often fatal side-effects. Our work shows that the protein B-II spectrin is downregulated during CAR-T production, and that restoring B-II spectrin levels decreases side-effects while increasing tumor clearance--hopefully translating to better CAR-T regimens for the future.

ABSTRACT IMPACT: This research will improve human health by increasing screening for hepatitis C virus, thereby decreasing morbidity and mortality from hepatitis C-related disease. OBJECTIVES/GOALS: The worldwide incidence of liver cancer increased 75% from 1990 to 2015 due, in part, to chronic hepatitis C virus (HCV) infection. Individuals born 1945-1965 (baby boomers) have five times the prevalence of HCV infection compared to other birth cohorts, but fewer than 15% of this cohort have ever been screened. METHODS/STUDY POPULATION: Effective interventions to increase HCV screening among baby boomers are urgently needed. In partnership with a provider advisory board and a community advisory board, we will develop a multilevel intervention designed to increase HCV screening that will be delivered to both providers and patients in primary care. We will assess whether the intervention is feasible, acceptable, and usable from the perspectives of the target audiences (providers and patients) by conducting Concurrent Think Aloud (CTA) interviews with eight patients and eight providers. RESULTS/ANTICIPATED RESULTS: While the specific content of both intervention components will not be finalized until the completion of the study, we envision that the provider-level intervention will likely include a one-time educational session and monthly performance feedback provided via e-mail reporting each provider’s HCV screening rates. The patient-level intervention may include mailed reminder letters prior to a scheduled clinic visit informing them that HCV screening is recommended and a tablet-based in-clinic computer program to educate, engage, and activate patients to be screened. DISCUSSION/SIGNIFICANCE OF FINDINGS: The goals of this project are to: 1) develop an acceptable, feasible, and usable multilevel intervention aimed at increasing HCV screening in primary care; and 2) understand the relationship between the intervention components and HCV screening; and 3) reduce HCV-related morbidity and mortality.

Objectives/Goals: The University of Minnesota (UMN) CTSI and Medical School sought to increase the diversity of translational research-intensive faculty by recruiting highly promising new-to-UMN tenure track faculty in the Medical School. Increased resources and career development will increase recruitment and address barriers to their promotion and success. Methods/Study Population: In 2019, the Medical School Dean committed to fund 15 Early Career Research Awards (ECRA) Scholars to recruit outstanding new-to-UMN, tenure track faculty. Supplementing usual departmental recruitment packages, ECRA Scholars receive: 75% salary and fringe benefit support for 3 years; an additional $500,000 of research funds; and augmented mentoring and coaching with required participation in the relevant CTSI career development program. Department Chairs propose meritorious candidates for Review Committee consideration based on the Chair nomination letter, scientific plan, mentoring plan, CV, and additional letters of recommendation. To foster community building, there is an annual mini-retreat for the ECRA Scholars and other underrepresented CTSI Scholars with an external visiting professor. Results/Anticipated Results: Fifteen tenure-track faculty have been recruited as ECRA Scholars since 2019 into 9 different departments. One additional Scholar has been accepted and three have completed the program. Three ECRA Scholars were K awardees at the time of recruitment. The CTSI career development programs utilized were the K Accelerator (10), KL2 Scholar (2), and K-R01 (5) Programs, with 3 involved in two programs. The Scholar degrees include 10 PhDs, 3 MD/PhDs, and 2 MDs, with additional MPH/MS (5), MSW (1), and DPT (1) degrees. ECRA Scholars have been awarded multiple NIH R21, Foundation, and internal grants currently under review include Ks and R01s with 5 additional K, 2 new R01, and 1 revised R01 submissions planned for the 2024–2025 academic year. Discussion/Significance of Impact: The ECRA program has successfully augmented recruitment of outstanding underrepresented research-oriented early-stage faculty to the University of Minnesota School of Medicine, contributing to many Departments. The CTSI has provided career development, networking, and a broader community of Scholars, with increased diversity in CTSI programs.

OBJECTIVES/GOALS: Rare mutations in CHCHD10 gene are found in 1% of patients with familial Amyotrophic lateral sclerosis (ALS). The overall goal of this study is to utilize induced pluripotent stem cells (iPSCs) as an in vitro model organism for rare ALS variants to evaluate the mechanism of transcription adaptation of CHCHD10/2 as a potential therapeutic. METHODS/STUDY POPULATION: Point mutations on normal iPSCs was performed via Donorguide CRISPR/Cas9. The single stranded RNA/DNA donors contain genetic alterations of CHCHD10: Pro12Ser, Arg15Leu, Pro23Leu, Pro34Ser, Ser59Leu, Gly66Val, Pro80Leu, Tyr92Cys and Gln102His. Ribonucleoprotein electroporation was used to transfect iPSCs and DNA sequencing was used to validate gene editing. To validate transcriptional adaption, changes in levels of protein and gene expression were measured via immunoblot and quantification of CHCHD10 and CHCHCD2 was performed from whole cells lysates of the edited iPSCs. RESULTS/ANTICIPATED RESULTS: We anticipate that CHCHD2 transcriptional adaptation can functionally compensate for the locus loss of function of CHCHD10. This mechanism of transcriptional adaptation may contribute to an explanation for variation in clinical manifestations of patient phenotypes. DISCUSSION/SIGNIFICANCE: This study supplies further evidence for genetic modification as a treatment option for diseases with point mutation causal or enabling mechanisms, including some variants of ALS. Future work will explore the gene-correction from an ALS patient with a known CHCHD10-R15L variant.

OBJECTIVES/SPECIFIC AIMS: Aim 1: To compare microbiome diversity among patients who develop BSI post hematopoietic stem cell transplantation (HSCT) and patients without BSI. Aim 2: To compare microbiome diversity among patients who develop moderate to severe acute GVHD post HSCT and patients without GVHD. Aim 3: To describe alterations in specific bacterial orders (Enterobacteriaceae, Clostridia, and Lactobacillales) in pediatric patients undergoing HSCT. METHODS/STUDY POPULATION: Next-generation sequencing of the hypervariable V3 region of the 16s rRNA gene isolated from stool specimens collected at baseline (start of preparative regimen to transplant day), early (day 7–14 post HSCT), and late (day 21–28 post HSCT) from 46 children was performed. Microbiome diversity was assessed by the Shannon index as well as UniFrac analysis, and compared among patients with and without GVHD/BSI. Baseline bacterial diversity was compared among patients by primary diagnosis, race, timing of antibiotic introduction and method of supplemental nutrition. RESULTS/ANTICIPATED RESULTS: Median age was 9 years (range 0.5–19.2 years). There were 36 patients with hematologic malignancies. Patients with nonmalignant disease had a characteristic pattern of microbiome diversity (and microbiota order distribution) at baseline that persisted throughout the first month of transplant (p=0.004). Over all patients, there was an early and persistent drop in microbiome diversity throughout the transplant course. Early introduction of broad spectrum antibiotics (prior to transplant day) negatively impacted microbiome diversity (p=0.02). There was no difference in microbiome diversity among patients who developed BSI, when compared with patients without BSI. Similarly, we did not find an association between microbiome diversity and the development of moderate to severe acute GVHD. Ongoing analysis is examining the individual variations in microbiome at the species level, and their relation to transplant characteristics and clinical outcomes. DISCUSSION/SIGNIFICANCE OF IMPACT: In our analysis, microbiome diversity decreased during HSCT, but in contrast to published data, mainly in adult HSCT populations, we found no association between gut microbiome diversity and GVHD or BSI. There are ongoing clinical trials in children and adults using probiotics in HSCT with the aim of decreasing GVHD. Further analysis of our data at the species level may further inform the relationship between gut microbiome alterations and HSCT complications in children and guide clinical interventions.

OBJECTIVES/SPECIFIC AIMS: The objective of this research was to assess the clinical impact of simulation-based team leadership training on team leadership effectiveness and patient care during actual trauma resuscitations. This translational work addresses an important gap in simulation research and medical education research. METHODS/STUDY POPULATION: Eligible trauma team leaders were randomized to the intervention (4-hour simulation-based leadership training) or control (standard training) condition. Subject-led actual trauma patient resuscitations were video recorded and coded for leadership behaviors (primary outcome) and patient care (secondary outcome) using novel leadership and trauma patient care metrics. Patient outcomes for trauma resuscitations were obtained through the Harborview Medical Center Trauma Registry and analyzed descriptively. A one-way ANCOVA analysis was conducted to test the effectiveness of our training intervention versus a control group for each outcome (leadership effectiveness and patient care) while accounting for pre-training performance, injury severity score, postgraduate training year, and days since training occurred. Association between leadership effectiveness and patient care was evaluated using random coefficient modeling. RESULTS/ANTICIPATED RESULTS: Sixty team leaders, 30 in each condition, completed the study. There was a significant difference in post-training leadership effectiveness [F(1,54)=30.19, p<.001, η2=.36] between the experimental and control conditions. There was no direct impact of training on patient care [F(1,54)=1.0, p=0.33, η2=.02]; however, leadership effectiveness mediated an indirect effect of training on patient care. Across all trauma resuscitations team leader effectiveness correlated with patient care (p<0.05) as predicted by team leadership conceptual models. DISCUSSION/SIGNIFICANCE OF IMPACT: This work represents a critical step in advancing translational simulation-based research (TSR). While there are several examples of high quality translational research programs, they primarily focus on procedural tasks and do not evaluate highly complex skills such as leadership. Complex skills present significant measurement challenges because individuals and processes are interrelated, with multiple components and emergent nature of tasks and related behaviors. We provide evidence that simulation-based training of a complex skill (team leadership behavior) transfers to a complex clinical setting (emergency department) with highly variable clinical tasks (trauma resuscitations). Our novel team leadership training significantly improved overall leadership performance and partially mediated the positive effect between leadership and patient care. This represents the first rigorous, randomized, controlled trial of a leadership or teamwork-focused training that systematically evaluates the impact on process (leadership) and performance (patient care).

ABSTRACT IMPACT: This work will help to identify ways to adapt family-based obesity treatment based on families’ food purchasing behaviors and beliefs. OBJECTIVES/GOALS: Families in obesity treatment are encouraged to make dietary changes. Dietary changes are impacted by food choices, which can be influenced by food cost. The objective of this research is to explore families’ food purchase behaviors and beliefs from the perspective of their health coach, and to assess how health coaches adapt treatment to address these. METHODS/STUDY POPULATION: Semi- structured telephone interviews were conducted with 10 health coaches in the Effectiveness of Family-Based Weight Loss Treatment Implementation in Primary Care (PLAN) study across four geographic locations in MO, NY, and OH. Topics covered were professional background, perspectives on working with families, and discussions with families regarding cost perception and food choice. Conventional content analysis was used through ‘open-coding’ of transcribed text by reading the transcripts and assigning labels. Codes were then organized into themes. In addition to the interviews, coaches were asked to complete a FRAME checklist to identify adaptations or modifications that were made to the treatment. RESULTS/ANTICIPATED RESULTS: The coaches reported that cost is a barrier to making healthier food choices for some but not all of their FBT families. Themes for cost as a barrier include: fast food is cheaper; justification to choose old food choices; sales on foods high in calories and sugar; bulk buying; and fewer sales on healthier options. Themes for what families consider when purchasing healthier items include: perishable foods, increased waste, picky kids, lack of knowledge about healthy eating on a budget, afraid of including new foods, and no money for new foods. The final stage of content analysis for the FRAME schematic checklist is ongoing. DISCUSSION/SIGNIFICANCE OF FINDINGS: The results exemplify that families’ have different food purchasing behaviors and beliefs and consider a variety of factors when making food choices. The data gathered from the FRAME checklists will help in characterizing the adaptations or modifications made by coaches and allow for better understanding of the impact on the families.

Objectives/Goals: Academic research centers struggle to recruit and retain a diverse, competent clinical and translational science (CTS) workforce. The clinical research professional career pathway is particularly underrecognized among undergraduates, despite offering multiple career opportunities. Methods/Study Population: To address these challenges, two undergraduate outreach programs were developed. First, an undergraduate certificate program in CTS (UC-CTS) was designed to equip students with the skills and knowledge needed to enter the workforce immediately after graduation. Second, a “CTS Roadshow” was launched to build awareness of CTS careers within a variety of undergraduate programs and majors. In this recruitment initiative, principal investigators (PIs) and CRPs visit classrooms to share information about CTS career pathways and offer insights into the roles, responsibilities, and professional opportunities available in the field. Results/Anticipated Results: The UC-CTS program launched in Fall 2024 as a 12-credit certificate that includes two paid internships: one in patient care and one in research. Currently, the program has 5 students enrolled with an anticipated increase in enrollment to 20 students by Spring 2025. Similarly, the CTS Roadshow has reached an increasing number of students each year. Since its inception in Spring 2023, the CTS Roadshow has introduced over 750 undergraduates across 21 courses to CTS careers. The CTS Roadshow has engaged students from a variety of majors, including biology, psychology, medical sciences, legal, finance, accounting, and pre-health programs, increasing awareness of and interest in CTS careers. Discussion/Significance of Impact: Both programs aim to expose students to CTS careers early in their education, better preparing them for full-time CTS roles after graduation. A rise in qualified applicants pursuing CTS careers locally and regionally is expected, improving job satisfaction and retention through enhanced preparation for the career field.

OBJECTIVES/GOALS:

• Develop strong network of science teachers interested in promoting scientific research to their students.

• Place students in an immersive summer research internship that, when possible, matches their career interests.

• Expose students to the numerous career paths within the STEM field.

METHODS/STUDY POPULATION:

• The program recruits socio-economically disadvantaged students and provides them a stipend, and also accepts students who can participate unpaid.

• Local school teachers are engaged in a summer fellowship to learn biotechnologies and research. In Spring these teachers help recruit students and during the subsequent Fall help students with college and scholarship applications.

• Students are placed in a variety of laboratories within the Schools of Medicine, Science, Dentistry, Public Health, Informatics, Health and Human Sciences, Engineering and Technology, especially in biomedical engineering. Students are also placed in industry laboratories such as Eli Lilly and the Indiana Bioscience Research Institute.

• Long-term program follow-up is done through post-internship surveys to assess impact on graduate and professional school admission.

RESULTS/ANTICIPATED RESULTS:

• Since the Indiana CTSI was established in 2008, 872 students have participated in the summer internship.

• 71% of past interns are underrepresented minorities in science or classified as disadvantaged by NIH criteria.

• 17% of students interned during grade 10, 72% during grade 11, and 11% during grade 12.

• 21% of students engage in the program for more than one year.

• 100% of past interns are currently enrolled in or have graduated college.

• Over 60% of those with a bachelors degree proceed to graduate and professional schools and over 80% stay in STEM related fields. These rates are equal for interns from underrepresented minorities or those classified as disadvantaged by NIH criteria.

DISCUSSION/SIGNIFICANCE OF IMPACT:

• Students engaged in the Indiana CTSI STEM program are progressing through the translational science pipeline based on their graduating from college and remaining in the STEM field.

OBJECTIVES/GOALS: This study engaged Black adults who reside in a rural area of Kentucky to explore their beliefs, norms, knowledge, attitudes, and health-related behaviors about Alzheimer’s disease (AD) (RQ1) and what message elements are most relevant for designing a health message aimed at encouraging them to get screened for AD (RQ2). METHODS/STUDY POPULATION: This qualitative study was guided bythe Integrative Model of Behavior. Participants were recruited from a faith-based institution in rural Kentucky. Black adults aged 50+ years were invited to participate in the study, which consisted of two focus groups. Group 1 gained information about behavioral determinants (RQ1) and examined which message design elements were important to Black adults by asking for feedback on a handout from the Alzheimer’s Association that encouraged AD screening (RQ2). The handout was redesigned based on feedback from Group 1. Group 2 was involved in a discussion of the redesigned handout, asking for further feedback. Focus groups were audio recorded and transcribed verbatim. Data analysis included thematic analysis of transcripts of the focus groups and quantitative analysis. RESULTS/ANTICIPATED RESULTS: Participants (N=18) were all female and Black with a mean age of sixty-two years. For RQ1, Results revealed that 1) limited knowledge of AD led to feelings of not being able to do anything about the disease, whereas awareness and education led to hope; 2) past healthcare experiences informed subsequent beliefs and behaviors, and 3) culture impacted beliefs, with a cultural norm of “what happens in our house, stays in our house” being prominent. For RQ2, results revealed the importance of regionally specific messaging for AD. Generic statements that applied broadly did not appeal to participants. Message delivery, layout, and format for low literacy individuals are key for maximizing audience impact. Pictures give hints about the message and aid in understanding. DISCUSSION/SIGNIFICANCE: Barriers such as past experiences, lack of knowledge, and cultural norms negatively impact the likelihood that Black adults will get screened for AD, resulting in delayed healthcare or healthcare avoidance. Regionally specific health messaging for AD has the potential to encourage modifications in health-related behaviors.

OBJECTIVES/GOALS: Evaluate if exposure to violence is associated with post-partum weight retention among WIC participants, which can lead to overweight/obesity due to metabolic adaptations associated to new adapted weight. If confirmed, it would highlight the need for revision of screening for violence exposure as social determinant of health among participants. METHODS/STUDY POPULATION: Nested cohort study among women enrolled in the Baby Act Trial (BAT) who have been enrolled to the active study phase and completed the Accountable Health Communities Health Related Social Needs survey from the Centers for Medicare & Medicaid services as the source of evidence of exposure to violence. BAT recruitment engaged women in their third trimester who were active participants of the Puerto Rico Women, Infants and Children Program (PRWIC), and planned to enroll their infant in the program. Anthropometric measures were documented at the following time points: prior to pregnancy, at delivery, and 12 months post-partum. Of the 530 women recruited to the study, 291 have completed study measures for inclusion into this exploratory analysis from this ongoing trial. RESULTS/ANTICIPATED RESULTS: A Total of 301 participants have met the criteria for inclusion in this preliminary analysis. Mean age among mothers was 26.5 years (SD 5.3), 46.6% had High School level education attainment or less, and 43.3% were actively working at the time of recruitment. Twelve percent of participants had BMI above 35 at 6 months post-partum, while the prevalence of violence exposure was reported as follows for each type of encounter: 3.3% responded yes to physical violence by friends of family, 9.7% reported exposure to insults or inappropriate treatment by any person including family or friends, 2% having been threatened by anyone including family or friends, 6.3% reported having been yelled/cursed at or insulted by anyone including family or friends. Even more concerning is that 7.5% reported severe social vulnerability. DISCUSSION/SIGNIFICANCE: Results reveals importance of providing integrated care in social assistance program. Participants belongs to vulnerable population with social determinants of health that affect the health care they receive. It shows that providing nutritional assistance it’s not enough to being healthy because other components also play a role in overall health.

Despite increasing attention to the importance of diverse research participants, success across the translational research spectrum remains limited. To assess investigator and research team training needs, we conducted a web-based survey exploring barriers in knowledge and practice. Respondents (n = 279) included those affiliated with the University of Wisconsin Institute for Clinical and Translational Research (ICTR). Although all respondents reported an abstract belief in the importance of diversity, factors associated with higher levels of best practices knowledge and implementation included: (1) use of federal funding; (2) having fewer years of experience; (3) recruiting healthy participants; and (4) having recruitment training.
