Objectives/Goals: This project will enrich our understanding of basal breast carcinogenesis, highlighting the distinct biological differences in breast cancer risk between non-Hispanic Black (NHB) or non-Hispanic White (NHW) women, but also has the potential to provide real-world solutions thereby contributing to reducing health disparities in breast cancer outcomes Methods/Study Population: In the biological investigation, I am utilizing a unique cohort of normal breast tissues from Mayo Clinic patients who underwent breast reduction surgery that have self-identified as NHB or NHW premenopausal women. From these tissues, we are able to subculture human mammary epithelial cells, which we will use for our consequent experiments. For the qualitative study, I aim to recruit up to 40–50 eligible NHB women identified at increased risk for breast cancer and conduct semi-structured qualitative interviews informed by the National Institute on Minority Health and Health Disparities Research Framework. Results/Anticipated Results: Gene expression profiling on our cohort of 15 NHB and 40 NHW premenopausal women identified a gene expression signature in NHB women indicative of elevated Hedgehog signaling, a key factor in triple-negative breast cancer (TNBC) development and progression. I hypothesize that persistent activation of Hedgehog signaling within NHB women instigates the proliferation and transformation of basal stem cells within the breast, thus fueling TNBC development. Understanding the perceptions and experiences of NHB women that are identified as being at an increased risk for BC will aid in the identification of barriers and facilitators to their risk reduction care and in turn provide implementation strategies that could contribute to alleviating the racial disparity seen in TNBC morbidity, mortality, and preventative care. Discussion/Significance of Impact: The significance of this project lies in its dual approach, uncovering basal breast cancer mechanisms in a high-risk group using normal breast tissue and evaluating the perspectives from NHB women to enhance the practical relevance of our findings.

Objectives/Goals: Research participation by adolescents and young adults (AYAs) is critical for advancing therapeutic interventions applicable across the life course. Identifying effective strategies to recruit and retain AYAs is challenging. This poster elucidates the process and outcomes of working with an AYA Health Research Board and surveying AYAs. Methods/Study Population: The AYA Health Research Board established in 2022 as part of an AYA Program within the UC Davis (UCD) Clinical and Translational Science Center (CTSC). The Board is composed of youth advisers, ages 13–39, from across CA. In 2023, the Program supplemented insights from the board with a national online survey of AYAs using the Amazon Mechanical Turk (MTurk) platform. Two separate instruments were administered, one on recruitment and another on retention, each with over 400 responses. The UCD AYA Board was then engaged to provide crucial insights contextualizing the survey findings, ensuring their relevance and applicability to the AYA population. Results/Anticipated Results: Overall, survey results indicate that AYAs are aware of health studies and clinical trials. Responses affirm that incentives are the biggest driver of AYA participation, while side effects were identified as the biggest reason to drop out of a study. Overall, youth appear more interested in participating in online studies versus those that require in-person appearances. Text messages, regular updates, and sharing of study results were identified as strategies to maintain participant engagement. Additional results will be available through a one-page factsheet for researchers to use as they think about retention and recruitment of AYAs. Discussion/Significance of Impact: Survey results will be made available to health researchers to help move the needle on recruitment and retention efforts of AYAs. This mixed-methods case study serves as an example of the impact AYAs can have on shaping research and validating survey findings.

Objectives/Goals: To evaluate the impact of social determinants of health (SDOH), specifically socioeconomic status and medical insurance coverage, on access to mental health services for adults aged 60 and older served by Federally Qualified Health Centers (FQHCs) in Puerto Rico. Methods/Study Population: A secondary retrospective analysis of electronic health records from FQHCs in Puerto Rico will be conducted to examine the relationship between SDOH needs and mental health service utilization among adults aged 60 years and older receiving primary care. SDOH data will be collected using the PRAPARE® tool, assessing factors such as socioeconomic status, insurance coverage, and emotional support, with a focus on identifying unmet needs. Multivariable and logistic regression models, using Stata v.17, will be employed to evaluate correlations between these SDOH factors and mental health service utilization, adjusting for age, gender, and mental health conditions. This analysis aims to quantify the impact of SDOH on access to mental health services and elucidate key barriers to care for older adults in Puerto Rico. Results/Anticipated Results: We anticipate that lower socioeconomic status, lack of supplemental insurance, and inadequate family support will be strongly associated with the underutilization of mental health services among older adults in Puerto Rico. These disparities are expected to be more pronounced in individuals with limited income, weaker family networks, leading to significant gaps in access to necessary mental health care. Barriers such as healthcare insecurity, financial hardship, and fragmented support systems will likely emerge as major obstacles. By including patients from both rural and urban regions, the study will capture the distinct challenges each population faces, enhancing the contextual relevance of the findings to broader populations, ultimately informing policy and developing intervention strategies. Discussion/Significance of Impact: The findings will provide crucial insights for developing targeted interventions to enhance mental health care access for older adults in Puerto Rico. These results will inform policy development and public health strategies, addressing disparities and promoting equitable care in underserved populations.

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

Objectives/Goals: To identify clinician and researcher barriers, facilitators and learning preferences for patient partner engagement in research. In addition, to describe the strategies, our Patient Partners Program has planned for building clinician and researcher capacity to engage patient partners in clinical research. Methods/Study Population: Our program to promote authentic patient–researcher partnerships to advance clinical and translational research is grounded in participatory approaches to maximize meaningful engagement. We utilized small group listening sessions with health care providers involved in clinical research at the University of Michigan, Michigan Medicine healthcare system. Insights from these sessions are informing the development of learning models and curriculum content. We used purposive sampling to recruit individuals (n = 12) with a wide array of patient engagement experiences across diverse clinical departments. The study materials and interview guide were co-created with a patient research partner who also participated in co-facilitating the listening sessions. Results/Anticipated Results: The interview guide included questions about the benefits, challenges, and supports to engagement and capacity building training programs for researchers. The listening sessions were recorded, transcribed, and analyzed for common themes. Preliminary findings have identified the following themes related to barriers: (1) identifying and onboarding patient partners, (2) communication challenges, and (3) institutional and structural challenges (e.g., time constraints and difficulty offering compensation) and facilitators: (1) institutional and administrative support, (2) flexibility, and (3) respect, trust, and partnership. Improved knowledge about how and when to engage patient partners was identified as a key component to build researcher capacity in patient partnered research. Discussion/Significance of Impact: Integrating patient partners into study teams accelerates innovation and translational science, increases the relevance of research findings, improves health outcomes and patient empowerment, and elevates the value of the patient perspective allowing researchers to gain a new point of view from an individual with lived experience.

Objectives/Goals: 1) Discuss process of pilot integration of Community Health Worker (CHW) services as a component of patient-centered healthcare service delivery in 3 clinic models. 2) Summarize profiles of patients who self-select to utilize CHW services. 3) Discuss social determinants of health impacts of underserved and historically marginalized populations. Methods/Study Population: The priority population consists of individuals living in Mobile AL at or below poverty level. USA Health Center for Healthy Communities (CHC) piloted the integration of CHW services at USA Health Stanton Road Clinic (SRC), at USA Student Run Free Clinic (SRFC), and as part of a Medi Hub Outreach Clinic with the historically underserved MOWA Choctaw native American population. SRC is a high-utilization clinic for uninsured or underinsured patients across the breadth of the Gulf Coast. The other 2 sites serve similar clientele. Social determinants of health (SDOH) screenings at intake facilitate CHW referral for a clients’ unique needs for support at healthcare or social care agencies. Referral summaries can then be used to guide planning, community collaborating partner intervention, and clinical quality certification, Results/Anticipated Results: Results include identification of referrals process by which CHWs are able to provide culturally competent support to persons accessing healthcare services at the 3 clinic models identified. Identification of top SDOH needs that preclude access to care among the patients served during a 24-month pilot period, e.g., (i) housing insecurity, (ii) food insecurity, (iii) transportation, (iv) health Ins, and (v) pharmacy access and payment assistance. Discussion of beneficial impacts for health care service delivery with other members of the multidisciplinary clinical teams as recorded referrals can be used to guide planning, clinic certification efforts Discussion/Significance of Impact: Patient utilization of CHW services though self-selective offers opportunities for equity in access to care services from direct SDOH impacts, where CHWs act as responsive resource coordinators within the multi-disciplinary service delivery team.

Objectives/Goals: Children with intestinal failure rely on central venous catheters (CVCs) for at-home delivery of hydration and nutrition to sustain life. CVC associated infections are the leading driver of morbidity in this population. It is currently unknown what challenges caregivers of this patients face for at-home infection prevention tasks. Methods/Study Population: This is a qualitative analysis of the clinical implementation of at-home CVC care. Participants will be caregivers of children with intestinal failure in the Children’s Hospital of Los Angeles’ Intestinal Rehabilitation Program (a program with a large Spanish speaking population). The study team will conduct, record, and transcribe four synchronous remote focus groups using Zoom, two in English and two in Spanish, with 4–6 participants per focus group (n = 16–24). Questions will focus on caregiver experiences of CVC care. Transcripts will be analyzed using rapid qualitative analysis, an implementation science-oriented approach. The study team will review transcripts and summarize key points into matrices to examine relevant themes and quotes efficiently and systematically, using midpoint data analysis. Results/Anticipated Results: Illustrative quotes of all themes and domains discussed by caregivers will provide a person-centered overview of the specific types of facilitators and barriers to infection prevention task performance. Focus groups will be conducted in January 2025 with analysis in February. Facilitators and barriers will be mapped onto the Capability, Opportunity and Motivation behavioral model (COM-B), allowing for additional topics participants introduce by participants. Facilitators and barriers will affect all domains of the COM-B model and may also describe factors that cross multiple domains or fall outside the COM-B domains. Facilitators and barriers may differ between English and Spanish speaking caregivers. Discussion/Significance of Impact: Identifying facilitators of and barriers to infection prevention tasks will allow clinicians to maximize infection prevention efforts and improve quality of life for caregivers of children with intestinal failure. Additionally, this bilingual study will have improved external validity and address potential language-related barriers to care.

Objectives/Goals: To assess the association between integrase strand-transfer inhibitor (INSTI) use and sarcopenia, pre-frailty, and frailty in people living with HIV (PLWH) compared to non-INSTI users and HIV-seronegative controls, focusing on changes in muscle strength, function, and physical activity over time. Methods/Study Population: We analyzed data from the MACS/WIHS Combined Cohort Study (CCS) as part of the SPPACE INSTI Study. Eligible participants were PLWH on ART for ≥2 years or individuals at risk for HIV, with exclusions for pregnancy, active tuberculosis, malignancy, or PrEP use. Participants were grouped into 1) INSTI group (PLWH who switched/added INSTI), 2) non-INSTI group, and 3) HIV-seronegative controls. A total of 2,071 women and 1,807 men (2006–2020) were included. Sarcopenia analyses (AIM 1) included participants with grip strength/BMI data, and frailty analyses (AIM 2) included those with frailty data. Results/Anticipated Results: We anticipate that INSTI use will be associated with a higher prevalence of sarcopenia, pre-frailty, and frailty compared to PLWH on non-INSTI ART and persons without HIV (PWOH). Specifically, we expect greater declines in muscle strength, grip strength/BMI, gait speed, and overall physical function in the INSTI group. Furthermore, we predict that the INSTI group will show increased frailty markers, such as unintentional weight loss, weakness, and slow walking speed, over time. These findings could highlight a critical need for monitoring physical health in PLWH on INSTIs. Discussion/Significance of Impact: PLWH may experience sarcopenia and frailty earlier than those without HIV, and INSTIs might contribute. Given their widespread use, it is essential to assess the link to improve prevention and care strategies for those affected.

Objectives/Goals: Now in its 10th year, Research Jam, Indiana CTSI’s Patient Engagement Core, has proven to be an effective approach to patient engagement, foregoing generalized CABs for study-specific groups, personally invested in the research. Here we share our methods to benefit CTSAs seeking deeper engagement. Methods/Study Population: Research Jam is unique from patient engagement efforts in other CTSAs in almost every aspect. The composition and background of our team, the methodology to our practice and often our outcomes. This poster will use 10 years of projects, publications, and participant evaluations to explore our approach both quantitatively and qualitatively to see how it has contributed to the Indiana CTSI’s commitment to community engagement. Results/Anticipated Results: We will present quantitative data from 10 years of participant evaluations illustrating that Research Jams are received positively by those that attend, and qualitative analysis of the evaluations around themes of feeling heard, valued, and integral in research. By finding themes in evaluations across 10 years of studies, with different topics, different population types, and different investigators, we can speculate on what aspects of our approach appeal to the community, contribute to their positivity toward research and researchers, and could be reproducible in other CTSAs. Discussion/Significance of Impact: We use “blueprint” instead of “toolkit” when describing our process, as we hope others can see this not as a tool to fix a problem, but a plan to be iterated on in agreement with the community that will benefit from it. The relationships researchers need to build with communities are not cookie cutter neighborhoods, but rich, colorful and vibrant ones.

Objectives/Goals: Nearly 42% of adults in the USA have obesity; women are disproportionately affected. Women with obesity that become pregnant are especially prone to developing health condition; thus, aid is needed to achieve appropriate gestational weight gain (GWG). GWG interventions would benefit from examining the effects of social support and stress has on GWG. Methods/Study Population: The proposed study will examine whether expecting mothers’ social support predicts their perceived stress. Also, examine whether receiving aid, in the form of weekly meal delivery, changes perceived stress. Lastly, this study will explore if social support mediates the relationship between meal delivery and perceived stress. The study will use data gathered from a pilot GWG intervention focused on providing pregnant women weekly meal delivery. Participants (N = 14) will complete 2 visits at 16–20- and 35–36-weeks gestation, while receiving weekly meal deliveries. Data from both visits will be used for the purpose of this study. Women’s social support will be measured using the Multidimensional Scale of Perceived Social Support. While stress will be measured via the Perceived Stress Scale. Results/Anticipated Results: Previous behavioral weight loss studies have found that individual who endorse experiencing social support report less perceived stress. Although the relationship has seldomly been examined in pregnant women, similar results are anticipated. Often aid, such as meal delivery, can impact perceived stress and is likely to cause a positive change. To our knowledge, this is the first study to explore whether social support mediates the changes in perceived stress after receiving weekly meal delivery. Therefore, there is no known literature to suggest anticipatory results. Discussion/Significance of Impact: Few studies have examined the association between social support and perceived stress in pregnant women. This study will examine the effects social support has on a pregnant women’s stress. The proposed study will aim to identify if meal delivery changes perceived stress. If so, the study will explore if perceived social support mediates this change.

Objectives/Goals: The Research Participant Advisory Group (RPAG) was born out of the concept that, by creating a structured way for researchers to collaborate with research participants and/or community, we can improve, grow, and support clinical/research-based research, from design to dissemination. Three distinct groups exist across our Academic Health Center (AHC). Methods/Study Population: The RPAG has 3 groups: The Cincinnati Children’s Hospital Research Participant Advisory Council (CCHMC RPAC) addresses clinical research needs, such as research design, recruitment, and consenting. Adult/youth research participants and family members (n = 21) provide feedback about how to improve a research process, form or other research tool. In Cincinnati’s underserved West End, the West End Community Research Advisory Board (WE C-RAB: n = 18) focuses on the needs of underserved minority groups and supports researchers wishing to do community-based research. The newly formed University of Cincinnati RPAC (UC RPAC; n = 17) addresses the UC research needs. All groups meet monthly and are offered a meal and incentive. All members have received training in the responsible conduct of research. Results/Anticipated Results: Over 70 researchers have brought research challenges to the RPAG groups over the last 8 years, leading to improved consent forms, more targeted recruitment, clearer language and a more streamlined screening process. RPAG member surveys indicate a greater understanding of clinical research challenges, critical health issues, and how research can benefit them. The WE C-RAB has improved community recruitment efforts, as well as survey and study design. Researchers highlight the importance of feedback in creating greater study participant engagement, indicating deeper understanding of the community/participant perspective and how to work “with” community. Ongoing WE C-RAB-faculty partnerships have led to at least 3 federally funded grants. Discussion/Significance of Impact: The 3 RPAGs provide the versatility to meet the needs of the diverse research spectrum across the AHC. This includes the type of research as well as the level or degree of participant/community engagement needed. RPAGs create greater connection and understanding leading to better participant experiences and the promise of better health outcomes.

Objectives/Goals: Community gardening can foster healthy behaviors among low-income communities. This project aimed to develop a community garden. The primary objectives of this project are (1) assessing the need for and perspective on a community garden at the childcare center, (2) installing the garden, and (3) engaging children in gardening education. Methods/Study Population: This project took place at a childcare center in Harrisburg, PA. Most (74.6%) residents identified as Black or Hispanic/Latino. Every child at the center was eligible for free or reduced lunch. A listening session was held with directly impacted community members to discuss the need for a community garden. Four caregivers, 1 early childhood educator and a master gardener (n = 6) attended the listening session, in which they shared their personal strengths and challenges in growing food. Attendees provided suggestions on what foods they wanted to grow. Children enrolled in the center’s summer program (n = 50) were then invited to participate in weekly gardening activities for 9 weeks. Activities were targeted to preschoolers (3- to 5-year-olds). Older children enrolled in the summer program were welcome to participate. Results/Anticipated Results: Feedback from the listening session was positive. Attendees provided ideas on what to grow and shared interest in expanding the garden to the broader community. Project staff installed four garden beds and planted a variety of herbs (basil, mint, and lavender), fruits (strawberry and melon), and vegetables (tomato, squash, pepper, and onion). Roughly 20–50 children were engaged in the garden each week. Eight weeks into the project, one member from the broader community noticed the garden’s growth and expressed gratitude to the staff, stating “I saw you when you first started planting. This is great what you are doing for the kids.” Children and the center’s staff responded positively to the activities. The staff expressed verbal gratitude for the project and were enthusiastic about maintaining the garden. Discussion/Significance of Impact: Developing a community garden was feasible in this sample and shows potential to (1) increase children’s food literacy and vegetable acceptance and (2) bridge the gap from farm to early childcare education. The project’s success paves way for future gardening initiatives that address food access issues within other diverse low-income populations.

Objectives/Goals: The study is designed to co-develop a genetics education digital platform with community participants. Diverse populations, especially African American communities, are less likely to participate in genetic testing and clinical trials. To increase participation and community input, we want community participants across Louisiana. Methods/Study Population: A cross-sectional, mixed-methods study will be conducted to assess interest in learning about genetics through a digital education platform and to adapt the platform based on participant feedback. Specific Aim 1 will be achieved by recruiting a diverse cohort and collecting demographic data to identify participants’ characteristics. For Specific Aim 2, 35 community participants will be enrolled as a co-design team to complete 5-week educational modules. Feedback from focus groups will guide iterative platform refinements, ensuring the platform is culturally tailored and user-friendly. Results/Anticipated Results: For Specific Aim 1, we anticipate that the majority of participants will express interest in learning about genetics through the digital platform, with demographic data revealing a diverse participant pool, predominantly from African American and Hispanic communities. For Specific Aim 2, we expect that all 35 co-design team members will complete the 5-week modules. Feedback from the focus groups is anticipated to highlight the need for more user-friendly navigation, culturally tailored content, and enhanced visuals. These insights will guide the refinement of the digital platform for improved engagement and accessibility. Discussion/Significance of Impact: This study addresses a critical translational barrier – underrepresentation of African descended communities in genetic testing. By developing a culturally tailored, digital platform to engage these populations, the project aims to reduce health disparities, enhance genetic literacy, and foster inclusivity in genomic research.

Objectives/Goals: As the aging population increases, maintaining cognitive and physical health becomes crucial. Executive functions (EF), including reaction time, sustained attention, and spatial memory, are essential for daily life and independence in older adults but tend to decline with age, especially in Alzheimer’s disease (AD) patients. Methods/Study Population: Physical balance (PB) impairments further exacerbate this decline, affecting the quality of life and independence. Balance training (BT) emerges as a potential non-pharmacological intervention to enhance EF. This study aims to 1) assess the association between PB impairments and EF deterioration in older adults with AD; 2) evaluate the impact of BT on EF enhancement in this population; and 3) explore changes in brain-derived neurotrophic factor (BDNF) biomarkers before and after physical activity related to BT. This pilot study employs a cross-sectional design with older Hispanic adults (>65 years) in Puerto Rico, comparing a control group without BT intervention to an experimental group with BT intervention. Both groups will be assessed for EF and BDNF biomarkers pre- and post-physical activity. Results/Anticipated Results: Expected outcomes include identifying significant correlations between PB impairment and diminished EF, demonstrating measurable EF improvements following BT, and evidencing sustained BDNF release post-BT despite PB impairments. By understanding the biological mechanisms linking BT and cognitive improvements, particularly the role of BDNF, this research could inform future strategies to mitigate cognitive decline in AD patients through targeted physical interventions. Discussion/Significance of Impact: The findings of this study could provide valuable insights into the development of new preventive interventions, enhancing the quality of life and independence for older adults.

Objectives/Goals: There has been a significant increase in the engagement of researchers with persons with lived and living experience, driven by a growing recognition of the invaluable insights and expertise these individuals bring to the research process. However, there remains a need for research teams to learn how to engage with patients and community partners. Methods/Study Population: The EMPOWER project is a collaborative of members with lived/living expertise of substance use during pregnancy. EMPOWER meets three times per month in support of their goals of patient-centered research, changing the narrative through conversations, and building the capacity of persons with lived experience to co-lead research. Through over 4 years of active collaboration and co-learning, EMPOWER has identified and created methods that support meaningful patient engagement and capacity building. Results/Anticipated Results: EMPOWER has identified the following methods that support meaningful engagement and capacity building: Mind-Mapping Exercises, Personal and Collective Journey Mapping, 8-month research training curriculum, Digital Storytelling, Learning Labs, and World Cafe Meetings. These methods have led to a collaborative of 20 individuals with lived experience of substance use to identify research gaps, prioritize research questions, design data collection tools, analyze research data, disseminate research results, and consult with healthcare teams in efforts to improve clinical care. To-date EMPOWER have given over 10 invited presentations and is currently writing manuscripts. Discussion/Significance of Impact: Meaningful patient and community engagement is critical to developing and implementing healthcare interventions. Unfortunately, engagement efforts are often lack in building capacity of patients and community, which impedes their ability to fully engage in all phases of research.

Objectives/Goals: To determine the acceptability of a mobile/school-based diabetes and prevention clinic to overcome transportation barriers and improve attendance at endocrinology appointments for youth with type 1 diabetes, type 2 diabetes, MODY diabetes, and obesity living in socially vulnerable communities Methods/Study Population: This study utilized a 3-phase implementation process focused on feasibility, demand, and acceptability. Phase 1: identified high-need areas using patient volume and disease control metrics. Collaborated with school districts to define needs, enrolled them through a memorandum of understanding, and subsequently recruited and consented existing patients attending these schools. Phase 2 piloted the program to refine logistics and workflows. Semi-structured interviews and surveys were conducted with caregivers to assess program acceptability and satisfaction. Phase 3 is ongoing and will track clinical outcomes including glycemic control, appointment attendance, hospital admissions, emergency department visits, and self-management metrics. Results/Anticipated Results: Demand for the program was high with 91% (10/11) of approached districts agreeing to participate. District enrollment was staggered, starting with 1 district in August 2023, expanding to 5 in September, 7 in October, and reaching 8 districts by May 2024. From August 2023 to July 2024, the school-based mobile clinic conducted 355 individual clinical encounters addressing diabetes and obesity. The encounters included 180 for type 1 diabetes, 69 for type 2 diabetes, 8 for MODY diabetes, and 98 for obesity. Interviews and surveys with 36 caregivers are ongoing to evaluate program satisfaction. Discussion/Significance of Impact: The data suggest that this innovative healthcare delivery model is feasible. District-level enrollment demonstrates a demand for the program. Results from the interviews and surveys will further characterize the program’s acceptability among caregivers and lay the groundwork for future efficacy testing.

Objectives/Goals: Pregnancy increases vulnerability to stress and mental health symptoms, particularly among Hispanic women in Puerto Rico (PR), a population with unique socioenvironmental adversities, such as poverty and natural disasters. This study examined the relationships between life adversities and psychological distress in this at-risk population. Methods/Study Population: Participants (n = 50) in this cross-sectional study were recruited from an obstetrician’s office in Southern PR. All participants provided written consent and completed the Adverse Life Experiences Scale (ALES, Cronbach’s alpha = 0.71) to identify lifelong adversities faced and the overall duration (chronicity). Measures of psychological distress included the Perinatal Anxiety Screening Scale (PASS, Cronbach’s alpha = 0.96), the Edinburg Postnatal Depression Scale (EDPS, Cronbach’s alpha = 0.87), the Perceived Stress Scale (PSS, Cronbach’s alpha = 0.79), and the Brief Resilience Scale (BRS, Cronbach’s alpha = 0.86). Descriptive and Spearman’s rho correlation analyses were conducted. Results/Anticipated Results: The mean age of the participants was 27.90 years (SD = 6.05), with most in the first trimester (66.0%). On average, participants reported 4.32 (SD = 3.1) out of 23 lifetime adversities. The most common adversities were natural disasters (60.0%), loss of a beloved (58.0%), and financial difficulties (38.0%). Nearly half (44.0%) experienced five or more adversities. A significant number of participants met the clinical threshold for anxiety (38.0%, PASS), depression risk (22.0%, EPDS), moderate-to-severe perceived stress (52.0%, PSS), and low resilience (24.0%, BRS). The overall duration of adversities was significantly associated with anxiety (rs = 0.50, p = 0.001) and stress (rs = 0.50, p = 0.007). Discussion/Significance of Impact: Hispanic pregnant women in PR face high levels of adversity and distress, which can negatively affect both maternal health and fetal development, influencing long-term child outcomes. Early identification and targeted interventions addressing adversities, can improve maternal mental health and child health-development outcomes.

Objectives/Goals: Here, we utilize deep learning to automate the analysis of dual X-ray absorptiometry (DEXA) scans in the UK Biobank (UKB) imaging dataset to enable a large-scale assessment of lumbar spine disc degeneration, low back pain, and socioeconomic status. Methods/Study Population: Study Population: The UKB is a biomedical database that includes lateral spine DEXA imaging for 50,000 participants. Deep Learning Model Development: A computer vision model was developed that receives a DEXA scan as input and outputs a quadrilateral that corresponds to the corners of 5 lumbar vertebral bodies. The model is a deep, fully convolutional, encoder–decoder network using DeepLabV3. Statistical Analysis: To determine our preliminary model accuracy, we used the intersection over union (IoU) metric.We analyzed data using an ordinal regression model to determine the relationship between income/ neighborhood level multiple deprivation index (MDI) and low back pain (LBP), as well as a mixed effects model to estimate the relationship between income/MDI and disc height index (DHI). Results/Anticipated Results: Our model predicted vertebral body quadrilaterals in training and unseen test data (train IoU  =  0.96, test IoU  = .91) and was used to infer data for 10,440 participants. Confirming previous studies, there were significant relationships (p0.05) between income or MDI and DHI (Figure 2). Discussion/Significance of Impact: Low back pain is the world’s leading cause of disability, and socioeconomic factors play an important role. We found no relationship between disc height index and socioeconomic status. Thus, disc degeneration may not be a factor in this low back pain phenotype.

Objectives/Goals: To develop an informatics framework that will allow study of environmental effects on stillbirth at large scale (i.e., US-level) and leverage recent advances in machine learning and artificial intelligence to produce reproducible results that can be compared across multiple institutional settings. Methods/Study Population: Experimental exposure data are often available in “absolute time,” where a clinical event can be anchored using a timeline transformation. We associate each stillbirth event with a set of {ti…ti+1}L shapelets [1] associated with a location, L, and time intervals for the entire dataset. These shapeless are aggregated using a state-of-the-art shapelet classifier [2]. An autoencoder is used to reduce the dimensionality of the stillbirth classification and to cluster stillbirth events according to their corresponding exposure patterns. The stillbirth cluster can be analyzed for other nonexposure (i.e., genetic, SDoH, and demographics) factors, which may be enriched and/or depleted. Results/Anticipated Results: The framework we are developing leverages a shapelet-based approach to produce clusters of stillbirth events according to their corresponding exposure patterns. These clusters can be analyzed for depletion or enrichment of nonenvironmental factors. This analysis will inform how to formulate (or not) class models of exposure that can be more informative and have better predictive power than overall population models. Moreover, the finding of depletion and enrichment of physiological properties of the individuals may lead to novel physiological hypotheses to better understand the injury mechanisms that the environmental exposure profile produces. Discussion/Significance of Impact: Nearly 20,000 babies are stillborn in the USA each year [3]. Environmental exposures, usually studied as time averages over certain periods of time, have produced mixed results for stillbirth risk [4]. However, temporal profiles matter [1], and we argue that they can be assessed using shapelet technology.

Objectives/Goals: This study tests the REDCap Clinical Data Interoperability Service (CDIS) for streamlined data extraction from electronic health records (EHRs) for research. Managed by Clinical and Translational Science Institute, IU Health, and Eskenazi Health, CDIS offers real-time data syncing, automated workflows, and HIPAA-compliant data security. Methods/Study Population: The REDCap CDIS uses the Fast Health Interoperability Resource (FHIR) Application Programming Interface (API) to extract data from EHRs. It includes the Clinical Data Pull (CDP), which automatically pulls EHR data into user-defined REDCap fields, and the Clinical Data Mart (CDM), which collects longitudinal patient data. Three use cases were selected to assess the CDIS’s effectiveness in extracting data from the IUH Cerner and Eskenazi Epic EHR systems. The technical team set up clinical data mapping and adjudication processes, simplifying complex manual data extraction. Results/Anticipated Results: The CDIS successfully achieved real-time data synchronization during pilot testing with each EHR system. We extracted demographics, drugs, procedures, labs, and conditions. The mapping interface supports many-to-one data point mapping for the study data dictionary, and the adjudication process ensures data quality before integration into the REDCap database. The CDIS also improved data security and HIPAA compliance. An implementation intake process was developed for Indiana University investigators, allowing them to use the service for affordable clinical data extraction from EHR systems. Discussion/Significance of Impact: The implementation and testing of the REDCap CDIS demonstratesits effectiveness in streamlining EHR data extraction for research. The CDIS facilitates real-time data synchronization, automated workflows, and enhanced data security, offering a cost-effective solution through collaborative oversight with research teams.
