OBJECTIVES/GOALS: The project goal was to conduct formative work using community-based participatory research (CBPR) to inform the development of a laundromat-based reproductive health literacy intervention (LI)informed by Passhe-Orlow and Wolf’s Conceptual Model. We provide insights to support the development of similar health literacy interventions. METHODS/STUDY POPULATION: In Phase I, we recruited female patrons over the age of 18 living in DC from 4 community laundromats. Participants completed a survey with validated measures to assess reproductive health knowledge, self-efficacy, and intentions to seek care. Open-ended questions assessed participants’ experiences accessing care, communication with health providers, and laundromat use. Data informed the development of a 2-3 minute reproductive health literacy intervention (LI) storyboard. In Phase II, in-depth interviews were conducted with reproductive health providers (midwives, obstetricians-gynecologists, women’s health registered nurses, women’s health nurse practitioners) working in the communities where the laundromats are located. LI acceptability and appropriateness were explored. RESULTS/ANTICIPATED RESULTS: For Phase I, we recruited 60 patrons. Participants (68.3%) expressed interest in a laundromat-based reproductive health literacy intervention (LI). Identified reproductive knowledge gaps included: unaware of fertile days (50.0%); believe prenatal care should begin after 2nd trimester of pregnancy (50.0%); unclear about pregnancy spacing (85.0%); unable to identify use for folic acid (91.7%); believe once a cesarean always a cesarean (53.3%). In Phase II, all 14 providers supported increasing community accessibility to health information: “we have to move beyond doing public health education in a provider’s office. That’s very outdated.” Providers identified the LI as an approachable, informative, and accessible way to disseminate health information. DISCUSSION/SIGNIFICANCE: Patron and provider input informed our choice of content, style, and delivery of the reproductive health literacy intervention. An essential aspect of our CBPR approach, this research will inform effective, appropriate reproductive health education despite barriers presented by access, transportation, and work schedules.

OBJECTIVES/GOALS: This study examines health provider andcaregiver influences on adolescent dual prevention strategies, or the use of condoms and another form of contraception, to informa clinically focused triadic intervention, involving caregivers, adolescents aged 15-17, and health providers. METHODS/STUDY POPULATION: Data for the 2021 Teen and Parent Surveywere two online, cross-sectional surveys, a national sample of adolescents aged 15-19, and a survey of caregivers of 15–17-year-old adolescents. Data were matched to create a dyadic dataset (n=273). Drawing from the Actor-Partner-Dependance Model we will conduct a secondary retrospective analysis, specifically cross-sectional univariate, bivariate, and multivariate logistic regression analyses on sets of influences around contraception and sexual health: communication with parents and health providers, information delivery of sexual health, condom attitudes and self-efficacy around preventative behaviors. RESULTS/ANTICIPATED RESULTS: In preliminary unadjusted analyses, 91% of the sample were cis-gender females (n=249), of which 32% (n=87) had sexual contact with someone who could get them pregnant. In the past, 35% (n=86) discussed birth control pills and 9% (n=24) discussed long-acting contraception with a health provider. In the last health visit, 29% (n=72) discussed STI prevention. Caregivers discussed sexual decision-making (49%, n=144), how to prevent pregnancy (62%, n=169), and how to prevent STIs (55%, 151) at least once in the past year. At last sex (n=49) most used condoms (47%, n=23), followed by birth control pills (33%, n=16), and withdrawal (14%, n=7). Additional predictors and adjusted analyses will be further examined. DISCUSSION/SIGNIFICANCE: Dual prevention strategies can be influenced by caregivers and health providers, but they are contingent on communication. Triadic interventions may consider involving both caregiver and health provider communication around sexual health prevention.

OBJECTIVES/GOALS: Partnering with the Housing Authority of Los Angeles, we launched a place-based initiative in the Nickerson Gardens housing development in South Los Angeles, where we apply our community engagement approach of listening and learning, and trust and relationship building, to deliver public health interventions in a discrete community. METHODS/STUDY POPULATION: Nickerson Gardens is the largest housing development in Los Angeles, with 1,066 units and over 3,000 residents. 58% and 40% of the residents are Hispanic and Black/African American respectively with an average yearly income of less than $30,000. To build trust and establish relationships, our team began attending community events, holding weekly educational workshops, and participating in the summer program for youth. We also held listening sessions in English and Spanish that asked aboutthe overall health of the Nickerson Gardens community, environment and public space, access and barriers to care, needed healthcare services, and the lived experience within Nickerson Gardens. RESULTS/ANTICIPATED RESULTS: To date, we have held eight 90-minute listening sessions in English and Spanish with 59 participants. The sessions provided insight into theneeded health and educational resources and services, the organizational structure of the housing development and how that impacts access to information and services, as well as the nuanced and area-specific transportation issues and the connection to safety concerns. These findings will inform the next phase of this initiative which includes convening a Coordinating Council composed of service providers and Nickerson Gardens residents. This council will oversee the coordination and implementation of needed services, help maintain accountability of the providers, and offer residents the opportunity to take ownership of the process. DISCUSSION/SIGNIFICANCE: Academic-community partnerships are an effective strategy to deliver public health interventions and promote health equity in under-resourced communities. We tested and measured impact in a distinct community to reinforce a widely-applicable place-based model.

OBJECTIVES/GOALS: In line with NCATS funding requirements, the Michigan Institute for Clinical and Health Research (MICHR) established a continuous quality improvement (CQI) process and used the process to guide the implementation of a benchmarking project to evaluate and set goals for MICHR’s production of Clinical and Translational Science manuscripts. METHODS/STUDY POPULATION: We aimed to increase the number of Clinical and Translational Science papers MICHR produces and to set a reasonable goal for improvement. Benchmarking was used to obtain a baseline and inform the identification of a reasonable goal for improvement. 11 Peer institutions were identified with similar funding levels. 1,225 Publications from 2022 for all 12 CTSAs were obtained from NIH Reporter. All publications were reviewed by title to identify probable CTS content. Two staff reviewers confirmed a total of 108 CTS publications across all CTSAs, and coded each paper to characterize the theoretical approach, method (quantitative and/or qualitative), analytic method and topic. All publications that were selected for benchmarking were also tracked and compared using Altmetrics for Institutions and Overton platforms. RESULTS/ANTICIPATED RESULTS: A total of 108 CTS publications were produced by 12 benchmarked CTSAs in 2022; of those, 70% (77) regarded research infrastructure, 37% (41) regarded research methods, and 15% (16) regarded clinical care. Over half, 53% (58), of the benchmarked papers are empirical research papers; of those, 67% (39) used quantitative methods, 28% (16) used qualitative methods, and 5% (3) used mixed methods. A clear majority of the benchmarked papers, 70% (76), provided only descriptive analyses, 18% (19) provided inferential analyses, and 12% (13) provided predictive analyses. We identified an opportunity to produce more manuscripts with descriptive analyses of research infrastructure. In the long-term, we saw an opportunity to produce predictive analyses of translational initiatives designed to impact clinical care. DISCUSSION/SIGNIFICANCE: The benchmarking results helped MICHR identify goals for its production of Clinical and Translational Science to fill gaps in the field. Expanding the scope of this benchmarking project might achieve greater interrater reliability using larger representative sets of publications drawn from institutions across the CTSA Consortium.

OBJECTIVES/GOALS: Clinical indicators predictive of venous thromboembolism (VTE) in trauma patients at multiple time points are not well outlined, particularly at time of discharge. We aimed to describe and predict inpatient and post-discharge risk factors of VTE after trauma using a multi-variate regression model and best of class machine learning (ML) models. METHODS/STUDY POPULATION: In a prospective, case-cohort study, all trauma patients (pts) who arrived as level 1 or 2 trauma activations, from June 2018 to February 2020 were considered for study inclusion. A subset of pts who developed incident, first time, VTE and those who did not develop VTE within 90 days of discharge were identified. VTE were confirmed either by imaging or at autopsy during inpatient stay or post-discharge. Outcomes were defined as the development of symptomatic VTE (DVT and/or PE) within 90 days of discharge.A multi-variate Cox regression model and a best in class of a set of 5 different ML models (support-vector machine, random-forest, naives Bayes, logistic regression, neural network]) were used to predict VTE using models applied a) at 24 hours of injury date or b) on day of patient discharge. RESULTS/ANTICIPATED RESULTS: Among 393 trauma pts (ISS=12.0, hospital LOS=4.0 days, age=48 years, 71% male, 96% with blunt mechanism, mortality 2.8%), 36 developed inpatient VTE and 36 developed VTE after discharge. In a weighted, multivariate Cox model, any type of surgery by day 1, increased age per 10 years, and BMI per 5 points were predictors of overall symptomatic VTE (C-stat 0.738). Prophylactic IVC filter placement (4.40), increased patient age per 10 years, and BMI per 5 points were predictors of post-discharge symptomatic VTE (C-stat= 0.698). A neural network ML model predicted VTE by day 1 with accuracy and AUC of 0.82 and 0.76, with performance exceeding those of a Cox model. A naīve Bayesian ML model predicted VTE at discharge, with accuracy and AUC of 0.81 and 0.77 at time of discharge, with performance exceeding those of a Cox model. DISCUSSION/SIGNIFICANCE: The rate of inpatient and post-discharge VTEs remain high. Limitations: single institution study, limited number of patients, internal validation only, with the use of limited number of ML models. We developed and internally validated a ML based tool.Future work will focus on external validation and expansion of ML techniques.

OBJECTIVES/GOALS: Low birth weight and preterm birth are significant contributors to infant mortality in the United States that disproportionally impact Black pregnant persons and their offspring. Although these outcomes are linked to chronic stress, the contribution of race-related stress remains largely understudied. METHODS/STUDY POPULATION: We investigated the effect of race-related stress on weight and gestational age at birth in a prospective cohort of 115 pregnant Black persons recruited at Grady Memorial Hospital in Atlanta, Georgia. The Index of Race-Related Stress Brief (IRRS-Brief), Perceived Stress Scale (PSS), and Stressful Events Questionnaire (SEQ) were collected at study enrollment during pregnancy. Neonatal birth weights and gestational age were collected via standardized medical record abstraction. We conducted linear regressions to determine whether greater race-related stress was associated with lower weight and gestational age at birth, while controlling for sources of prenatal stress. RESULTS/ANTICIPATED RESULTS: Global racism (total IRRS score) was significantly associated with birth weight when controlling for prenatal perceived stress and stressful life events within the last six months since study enrollment (beta=−16.7, p=.035). Neonatal gestational age was associated with both global racism (beta=-0.03, p=.028) and individual racism (IRRS’Individual’ subscale score) (beta=-0.09, p=.032) when controlling for prenatal perceived stress and stressful life events within the last six months since study enrollment. These results suggest that greater race-related stress contributes to lower weight and gestational age at birth in pregnant Black persons. DISCUSSION/SIGNIFICANCE: Future studies are necessary to determine the mechanisms by which race-related stress contributes to these adverse birth outcomes and to inform the development risk-assessment tools and interventions to mitigate the threat of race-related stress on adverse birth outcomes in high-risk populations.

OBJECTIVES/GOALS: To present Substance Abuse Research: Bench to Community (SARB2C) as a model for team science both within and between institutions. Emerging from targeted efforts by the NIH to engage translational scientists in prominent public health issues, the initiative illustrates the benefits of bringing together researchers and trainees to share ideas. METHODS/STUDY POPULATION: In 2019 a group was formed at University of Florida to discuss ongoing translational research in the area of substance abuse, including faculty, staff, and trainees from across the campus. The group was expanded in February 2022 to include domestic colleagues at the University of Kentucky as well as international collaborators at Chulalongkorn University in Bangkok, Thailand. One-hour monthly meetings began in person but now take place virtually. Larger projects are discussed individually, focusing on opportunities for collaboration. Attendees also provide updates on their work, including proposals in development and manuscripts in process. This facilitates dialogue around the science, from the bench to the community, and connects people to advance team science. RESULTS/ANTICIPATED RESULTS: In light of the ongoing opioid epidemic and the public health threat of other emerging substances, collaboration among researchers in this area is essential to advance the science and explore real-world solutions. SARB2C demonstrates the benefit of connecting researchers across T0 to T4, and that of including trainees for invaluable experience. This environment fosters open discussion and creativity and helps break down the silos that impede science. A highlight from early in the group’s history was a visit from the Program Officer for the UF Clinical and Translational Science Institute in February 2020. Since that time, multiple collaborations have resulted in grants submitted, such as P30 center grants and an innovative R61/R33, as well as numerous publications. DISCUSSION/SIGNIFICANCE: A complex public health emergency like the opioid epidemic requires creativity and collaboration, from laboratory science to interventions in the community, putting it squarely within the sights of translational research. SARB2C will soon enter its fifth year of linking researchers and training the next generation of scientists.

Emerging from targeted efforts by the NIH to engage translational scientists in prominent public health issues, the initiative illustrates the benefits of bringing together researchers and trainees to share ideas. METHODS/STUDY POPULATION: In 2019 a group was formed at University of Florida to discuss ongoing translational research in the area of substance abuse, including faculty, staff, and trainees from across the campus. The group was expanded in February 2022 to include domestic colleagues at the University of Kentucky as well as international collaborators at Chulalongkorn University in Bangkok, Thailand. One-hour monthly meetings began in person but now take place virtually. Larger projects are discussed individually, focusing on opportunities for collaboration. Attendees also provide updates on their work, including proposals in development and manuscripts in process. This facilitates dialogue around the science, from the bench to the community, and connects people to advance team science. RESULTS/ANTICIPATED RESULTS: In light of the ongoing opioid epidemic and the public health threat of other emerging substances, collaboration among researchers in this area is essential to advance the science and explore real-world solutions. SARB2C demonstrates the benefit of connecting researchers across T0 to T4, and that of including trainees for invaluable experience.

OBJECTIVES/GOALS: Our team has developed a high-throughput 3D patient-derived muscle platform to study signaling pathways associated with skeletal muscle disease. This platform will be used to study pathologies of human muscle that arise from genetic mutations and processes of aging along with pharmacologic interventions to improve mass, function, and performance. METHODS/STUDY POPULATION: In the current study, 3D skeletal muscle is formed from young healthy male samples. Samples are treated with urocortin II (UCNII) or vehicle for ten days and evaluated for tissue performance. Functional assessments include real-time contraction magnitudes using digital image correlation (DIC) analysis of video collected during electrical pulse stimulation and end-point measures of initial and repeated tetanic force production. Functional measures provide indices of patient muscle synchronicity, strength, and endurance related to drug efficacy and toxicity which we will correlate to pro-growth protein signaling via Luminex. A subset of these samples will also be analyzed by histology and microscopy to assess muscle fiber density, type, and size, as well as myotube fusion index and sarcomere uniformity. RESULTS/ANTICIPATED RESULTS: We anticipate that healthy muscle treated with UCNII will have increased synchronicity and contraction magnitudes in DIC analysis throughout their seven-day electrical pulse stimulation protocol. We also expect to see sustained contraction magnitudes in DIC analysis at the end of electrical pulse stimulation indicating fatigue resistance in the drug treated group compared to no-drug control. Like our real-time DIC data, we anticipate increases to initial and sustained maximal force production in the drug treated group. We expect that drug treated muscle will present with an increased fiber density, fiber diameter, and fusion index with uniform sarcomeres. Finally, we expect heightened pro-growth signaling pathways in treated vs. controls. DISCUSSION/SIGNIFICANCE: The current study will serve as an initial investigation of the endogenous ligand UCNII for enhancing skeletal muscle mass and performance in human muscle laying the framework for future drug efficacy and toxicity studies. This platform will ultimately enhance the study of muscle diseases and translation of therapeutics to clinical settings.

OBJECTIVES/GOALS: The study aims to explore the role of microglial behavior in cognitive impairment associated with vascular dementia (VaD) and long COVID. Using immunohistochemistry (IHC) and quantitative PCR (qPCR), we will assess the expression of Iba-1, a microglial activation marker, in subjects with VaD and SARS-CoV-2 infection. METHODS/STUDY POPULATION: Out of 48 female C57BL/6 mice, 24 had surgical intervention in the form of bilateral carotid artery stenosis (BCAS) for experimental induction of vascular dementia. After 2 weeks, 12 BCAS and 12 non-BCAS were infected with 1E4 PFU of mouse-adapted 10 (MA10) strain of SARS-CoV-2. 2 weeks post-infection, 4 weeks post-operatively, all animals were euthanized and tissues were processed for cDNA and histology. Immunofluorescence and RT-qPCR used to quantify microglia via Iba-1, BBB integrity via claudin-5 as well as occludin, GFAP, and integrin a5. RESULTS/ANTICIPATED RESULTS: We anticipate observing distinct patterns of microglial behavior in subjects with vascular dementia (VaD) and those with long COVID. Through immunohistochemistry (IHC), we expect to see increased Iba-1 expression, indicative of microglial activation. Quantitative PCR (qPCR) will likely corroborate these findings, showing elevated levels of Iba-1 mRNA. Lastly, we anticipate that the data will reveal interactions between microglia and the blood-brain barrier (BBB). These interactions could provide insights into how microglial behavior influences BBB integrity and, consequently, cognitive function in VaD and long COVID. DISCUSSION/SIGNIFICANCE: This study aims to clarify the role of microglia in cognitive decline linked to vascular dementia and long COVID. By categorizing patients based on microglial activation, we can better tailor treatments. The findings could lead to targeted therapies that address cognitive impairment in these conditions.

OBJECTIVES/GOALS: Theater has always served as a means of reflecting and understanding the human condition. Participatory theater further offers the option for viewers to participate in and thus additionally benefit from the performance itself. We use Playback Theater for outreach and research, eliciting information to guide research, education, and engagement. METHODS/STUDY POPULATION: Playback Theater is a type of improvisation that involves audience members recounting personal experiences which are then enacted by a theater troupe. Playback has evolved to include storytelling as a means of expressing and understanding difficult life experiences such as violence, bullying, incarceration, disaster, illness, etc. While not intended as therapy, it has been found to provoke insight and catharsis when used by trained practitioners. We are conducting Playback theater with LGBTQ+ and African American women to elucidate health disparities related to HIV/AIDS. Black/African Americans accounted for 42.1% of cases in 2019, and African American females are 15 times more likely to develop AIDS than white females. We hope to elucidate barriers to screening and treatment to inform early intervention. RESULTS/ANTICIPATED RESULTS: In community engagement, we employ a variety of strategies involving storytelling, since this simple act fosters multiple positive outcomes. For example, by talking about their experiences participants might find clarity about a difficult experience, facilitating coping or healing, or even letting go. By sharing their stories, others (clinicians, researchers, other patients, or the public) can learn what it is like to go through a particular illness or event. This knowledge can be used to allay patient fears or help researchers or clinicians to develop programming that better responds to needs. This novel approach to knowledge sharing also allows communication that may not otherwise be possible. Discussions about sensitive topics are enabled, often leading to shared understanding and potential solutions. DISCUSSION/SIGNIFICANCE: Through Playback Theater, we hope to identify and thus be able to address barriers to early screening and treatment for African American women and the LGBTQ+ population. We are also planning an event with children with cancer and their families to better understand their experiences and needs in both the clinical and familial settings.
