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.

OBJECTIVES/GOALS: Coordinating research studies is multifaceted and requires a foundational level of research knowledge, skills and abilities in order to contribute to high-quality, ethical research projects that adhere to local and federal regulations as well as Good Clinical Practice. Oftentimes, coordinators who are new to research or new to an institution have trouble navigating the research landscape. Departments within the University of Minnesota have limited resources to devote to developing robust training programs above and beyond protocol or department-specific training. Therefore, UMN’s CTSI created a comprehensive training and support program for research professionals at the University of Minnesota. METHODS/STUDY POPULATION: CTSI employs several strategies to provide a comprehensive training program for the University of Minnesota Research Workforce. The offerings are based on the The Joint Task Force for Clinical Trial Competency (JTF). In addition to training programs, valuable resources, materials, and connections are provided to trainees.

• An Onboarding process for new coordinators that includes a welcome email upon hire that provides resources as well an opportunity to meet face-to-face to get their questions answered about where to start with research training.

• Foundations for Research professionals, two week (20 hour) training program, provides a foundational level of knowledge to new coordinators via in-person and online training modules.

• Informed Consent 1 & 2 provides in-person training on the informed consent including the process, documentation, and ethical issues around consenting vulnerable populations.

• Over 40 on-line research training modules that coordinators can take at anytime.

• An active list serv that connects >600 research professionals with training updates and opportunities.

• Bi-weekly seminar series that provides a forum to share current regulations, best practices, resources, and guidelines pertaining to clinical research at the University.

• An online training “Roadmap” tool that customizes individual research training plans, and includes an inventory of training available.

RESULTS/ANTICIPATED RESULTS:

• 218 research professionals participated in our Foundations blended training program with 191 completing (88% completion rate) the entire training. A comprehensive assessment based on national competencies is completed by all participants at Baseline and Post training. Baseline scores average at 75% and Post scores average at 82% (7% increase). Satisfaction is measured and participants are overall satisfied with the training, 4 out of 5 on a Likert Scale.

• 353 research professionals have participated in our Informed Consent Session 1 & 2 in-person training. Satisfaction is measured and participants are overall satisfied with the training, 4.5 out of 5 on a Likert Scale.

• Over 190 research professionals have utilized our research on-line training modules.

• Training participants have been from 27 different departments across the University.

• The Clinical Research Professional Development Seminar Series has offered over 87 seminars with 4907 total attendees. These seminars are offered in-person and live stream.

DISCUSSION/SIGNIFICANCE OF IMPACT: Establishing a comprehensive training program at the University has streamlined the training that research professionals receive across departments. It also ensures that all coordinators have access to research training, a network of other research professionals, resources, and continuing education opportunities.

OBJECTIVES/SPECIFIC AIMS: Leadership is an essential and recognized team science competency. Modeled after the successful LEAD (Leadership in Emerging Academic Departments) program at University of Texas Southwestern (UTSW), ConduITS LEAD Program is designed to: (1) provide personal and professional development opportunities for participants; (2) promote organizational change through applied leadership skills; (3) provide a platform for integrating multiple disciplines and fostering interprofessional relationships among investigators and clinicians. METHODS/STUDY POPULATION: The 1-year structured LEAD program curriculum includes monthly interactive seminars covering: personal and situational leadership; unconscious bias; communication and influence; navigating personal conflict; negotiation and networking; selecting and managing the right team; teamwork; financing the academic mission, budgets and business plan development; strategic planning and vision; presentation skills. To foster the development of leadership skills participants engage in Hogan Assessments, individual and peer mentoring from an executive coach and self-directed learning activities and assignments. Completion of an individual Capstone leadership project empowers learners to enact practice change through the implementation of leadership concepts in practice. RESULTS/ANTICIPATED RESULTS: In collaboration with the Office of Academic Enrichment & Development (OADE), the first competitive RFA was issued in November of 2016. In total, 63 applications were received including: gender: 29 M: 34 F; URM: 10; Degrees: M.D. (40); Ph.D. (11); M.D./Ph.D. (6); M.D./M.P.H. (3); M.D./M.S.C.R. (2); PharmD (1); Departments: 19; Institutes/Centers: 12; MSHS: 3 sites. Through a competitive and rigorous application process, 24 junior faculty with evidence of leadership potential and trajectory were chosen to participate. The current cohort of LEAD participants joined in February 2017, and will complete the program in January 2018. Using qualitative and quantitative survey methodology, participants will be evaluated for self-reported change to attitudes, belief, skills and development of new relationships and collaborations. Submitted Capstone projects were mainly focused on implementing situational and personal leadership concepts to practice, with one additionally focused on the use of behavioral interviewing techniques to optimize team building and teamwork. At the time of abstract submission 30% of the cohort has implemented their Capstone project in practice. Participants will be followed-up in 6 months’ time to evaluate the impact of the LEAD program on their practice. Following a second RFA, 24/52 candidates have been selected as our next cohort, and will start in February 2018. DISCUSSION/SIGNIFICANCE OF IMPACT: Leadership is known to be a core component of team science, and the ability to implement leadership into practice may advance personal and professional change. This program addresses the need to empower Junior Faculty to engage in leadership in practice. In addition, this program is able to provide added value to extend the reach of the OADE, promote new individual collaborations and facilitate additional leadership training efforts at our Institution. Future collaborative studies will focus on common outcomes as well as institutional differences between these 2 CTSA institutions.

ABSTRACT IMPACT: A robust and collaborative network of expertise and services is essential for successful research commercialization, including timely and scalable educational support for CTSA institutions and individual faculty investigators with biomedical innovations. OBJECTIVES/GOALS: Leverage expertise at the University of Michigan (UM) by creating collaborative and scalable interactive online courses to instruct and prepare internal and external faculty to navigate critical stages of life science academic research commercialization. METHODS/STUDY POPULATION: UM’s Fast Forward Medical Innovation created two online courses with the UM Office of Technology Transfer and the Michigan Institute for Clinical & Health Research (MICHR). Collaborative planning committees, with content and educational experts, set course goals and learning objectives based on audience needs (e.g. preparation for consultations, commercialization concepts, etc.). Draft content was developed, peer reviewed, and revised before Articulate Storyline was used to convert didactic content to active learning content (e.g. interactive slides, scenarios, quizzes, and forms). Pilot testing was conducted prior to the launch to faculty investigators throughout the UM network. RESULTS/ANTICIPATED RESULTS: Intellectual Property in the Academic Setting launched via the FFMI website and newsletter in July 2020 and has had 66 learners to date. Medical Device Regulations launched in October 2020 and has 22 learners. OTT and MICHR have successfully integrated the courses into their consultation process by requesting review from faculty investigators. We suspect that this will lead to more in-depth and meaningful conversation. Additionally, these courses have been integrated into an FFMI commercialization course to instruct on critical concepts. Evaluation and refinement for both use cases will ensue, as well as inform future collaborative courses. DISCUSSION/SIGNIFICANCE OF FINDINGS: Early results suggest that the courses are advantageous and can serve as a model for future collaborations. The opportunity to disseminate the courses across the CTSA network, as well as collaborate with other institutions, to scale localized expertise to a broader network is promising.

OBJECTIVES/SPECIFIC AIMS: Patients with epilepsy often combine their antiepileptic drugs (AEDs) with complementary medicine (CM). They use CM to treat their symptoms of comorbidities disorder, to reduce the side effect of the AEDs or trying to achieve better control of their seizures. However, the inconsistent patters of the use of CM among countries have been attributed to cultural and socio-economic factors and limited studies have explored biological factors. The aim of this study is to determinate whether or not there is an association between having genetic polymorphisms on candidate pharmacogenes for drug-metabolizing enzymes cytochrome P450 (CYP) and the use CM among patients with drug-resistant epilepsy (DRE). METHODS/STUDY POPULATION: In this cross-sectional study, patients will be recruited in the Epilepsy Clinic in the Medical Science Campus of University of Puerto Rico and in private Neurology clinics. To participate in this study, patients need to have both parents of Puerto Rican origin to be defined as Puerto Rican and have a diagnosis of DRE, defined as persistent seizures after at least 2 good trials of the proper drugs at the right dose. After the patient sign, the inform consent, a buccal swap will be collected, and the patient will complete a questionnaire. In the questionnaire, the patient will do a self-report about the use of CM (including natural products, meditation, yoga, and others), frequency of use and socio-economic information. Polymorphisms for CYP 2D6, 2C9, 2C19, or 1A2 will be determined using TaqMan® SNP Genotyping Assays. Data analysis will include descriptive statistical, χ2 and ANOVA test. RESULTS/ANTICIPATED RESULTS: We expected to determine the frequency distribution of functional polymorphisms on CYPs among patients with DRE who are either using CM and AEDs or standard care (AEDs). Quantified the use of CM and ascertain if there is an association with the CYPs polymorphisms. DISCUSSION/SIGNIFICANCE OF IMPACT: This study is novel, because we will use an objective test, pharmacogenetics approach to rule out biological factors associated with the use of Complementary Medicine by patients’ DRE. The study will provide evidence for prospective study using specifics Complementary Medicine guiding by genotyping.

Objectives/Goals: Professional coaching greatly enhances faculty personal and professional development through fostered empowerment and a culture of continuous growth within the academic environment. The UMN Clinical and Translational Science Institute (CTSI)’s coaching program provides a variety of coaching formats (1:1, group, special programs). Methods/Study Population: CTSI provides professional coaching to faculty in the KAP, K12, KL2, and K-R01 and NLITeS programs. Typically, coaching begins with a HoganLead™ assessment and debrief. Scholars may pursue further coaching through individual sessions (up to 6 sessions during or 1-year post CTSI award) or a monthly peer coaching group facilitated by certified coaches. New URM faculty hires in the Early Career Research Awards (ECRA) program receive monthly coaching support to problem solve and attend to wellbeing. The NLITeS leadership development program for senior and mid-career faculty includes the HoganLead debriefing and 1–2 individual coaching sessions. All sessions are confidential. Results/Anticipated Results: Since 2016/2017, 80 scholars have taken the HoganLead assessment (72 debriefs), and 23 scholars have made use of 217 individual coaching sessions (most use between 6 and 12). Since 2021, 10 Scholars have participated in the Peer Coaching Group with 7 continuing over multiple years. Since 2021, 12 ECRA scholars have been supported in monthly coaching. Frequent coaching topics include self-awareness, work-life balance, overwhelm, negotiation, and leaving academic medicine. Scholar comments include: “I initially approached this professional coaching with some curiosity but fairly minimal expectations that it would change much. It has reshaped the way I approach my academic career and its associated challenges for the better, giving me confidence that I can handle the unique challenges that this career presents…” Discussion/Significance of Impact: The UMN CTSI coaching programs are extensively used and highly valued by participating faculty. Professional coaching with Hogan assessments provides faculty scholars with support that complements the mentoring they receive by going beyond a teach and learn model.

OBJECTIVES/SPECIFIC AIMS: (1) Evaluate the auditory narrative process as a learning experience for interviewer, editor, and interviewee. (2) Discuss methodologies for developing or selecting audio narratives and suggest how to effectively integrate them into the DPT curriculum, or thread into individual coursework. (3) Experience and appraise podcast components developed for a DPT psychosocial aspects of disability course. METHODS/STUDY POPULATION: Students were provided preassessment and postassessment on empathy. Other methodologies include conducting interviews, developing story boards, and editing audio narratives. RESULTS/ANTICIPATED RESULTS: Learner feedback indicated that course material was experienced in a way that deepens one’s understanding of the complex and challenging issues facing patient, caregivers, and themselves as they embark on their profession. DISCUSSION/SIGNIFICANCE OF IMPACT: The utility of integrating different modalities within coursework is to enrich learner experience to encourage self-reflection and awareness of not only their identity but that of multidisciplinary collaborators.

OBJECTIVES/GOALS: Idiopathic Pulmonary Fibrosis (IPF) is a fatal disease of lung scarring. Aberrant vascular remodeling is a contributor to IPF progression. We have identified CCN3 as an endothelial gene that is upregulated in resolving but not in persistent lung fibrosis in mice. Here we tested the role of CCN3 in lung microvascular endothelial function. METHODS/STUDY POPULATION: RNAi loss of function experiments were used to evaluate the role of CCN3 in lung endothelial biology. Human lung microvascular endothelial cells (HLMECs) were transfected with human CCN3 siRNA and analyzed via qPCR to assess expression of endothelial transcripts, via wound healing assay for assessment of migratory function, and via 2D tube formation assay for assessment of angiogenic function. To ascertain the effect of HLMECs on Normal Human Lung Fibroblasts (NHLFs), conditioned media (CM) from endothelial cells with control and CCN3 siRNA was applied to TGFβ primed fibroblasts and qPCR was used to measure expression levels of pro-fibrotic transcripts. Recombinant human CCN3 protein was subsequently used to confirm the gain of function role of CCN3 in lung endothelial biology using a subset of these assays. RESULTS/ANTICIPATED RESULTS: CCN3 is a secreted matricellular protein thought to be involved in angiogenesis, cell adhesion, cell migration, and inflammatory responses in endothelial cells. In other organs, CCN3 suppresses expression of fellow matricellular protein, CCN2 (CTGF); importantly, CCN2 is a known pro-fibrotic mediator of aberrant tissue remodeling in the fibrotic lung. Upon CCN3 knockdown in HLMECs, we observed reduced transcripts for inflammatory and pro-fibrotic genes, along with impaired endothelial function in wound healing and angiogenesis assays. CM from CCN3 knockdown endothelial cells enhanced the pro-fibrotic effects of TGFβ in NHLFs. Addition of recombinant CCN3 to HLMECs generated, conditioned media that reduced fibroblast pro-fibrotic activation. DISCUSSION/SIGNIFICANCE: We have shown that matricellular protein- CCN3 plays a fundamental role in endothelial identity and function and could be a promising therapeutic target in IPF. A future goal is to restore levels of genes such as CCN3 in the aged vasculature in the setting of lung fibrosis to test their capacity to promote vascular repair and fibrosis resolution.

OBJECTIVES/SPECIFIC AIMS: Evaluate the effect of multijoint functional electrical stimulation (FES) on energy consumption during post-stroke walking. METHODS/STUDY POPULATION: A 67-year-old male with chronic stroke was implanted with an 8-channel implanted pulse generator to stimulate flexor and extensor muscles of the hip, knee, and ankle. Oxygen consumption was measured with a k2b4 portable pulmonary gas analyzer during walking with and without FES assistance. Data were analyzed during steady state oxygen consumption within the last 2 minutes of a 5 minute walk. Distance and walking speed were also measured. RESULTS/ANTICIPATED RESULTS: Electrical stimulation increased walking speed from 0.29 to 0.64 minute/second. Faster walking corresponded with increased oxygen consumption from 10.1 to 14.4 mL O2/kg per minute. Energy cost, consumption as a function of distance, decreased from 3.7 to 2.9 mL O2/kg per minute walking with stimulation compared with without. DISCUSSION/SIGNIFICANCE OF IMPACT: These preliminary data suggest improvements in walking speed with FES are accompanied by increased energy consumption and decreased energy cost. Oxygen consumption during FES assisted walking was <50% of the peak for able bodied individuals of similar age; patients may successfully use the system for community ambulation.

OBJECTIVES/SPECIFIC AIMS: Acute myeloid leukemia (AML) is a devastating hematologic malignancy wherein <20% of patients will survive 5 years after diagnosis. In an effort to understand alterations that drive AML development and progression, The Cancer Genome Atlas detailed the most common recurrent mutations. One gene of interest identified here was HNRNPK, supporting our clinical observations that suggest altered expression levels of HNRNPK and its corresponding protein (hnRNP K) may impact AML. Here, we aim to elucidate the impact of hnRNP K overexpression in AML by utilizing AML cell lines and mouse models reflective of the human disease. METHODS/STUDY POPULATION: We utilized fluorescence in situ hybridization (FISH), qRT-PCR, and reverse phase protein array (RPPA) to evaluate HNRNPK copy number and expression levels in AML patient samples compared with CD34+ cells from healthy human donor bone marrow. Kaplan-Meier survival analyses were performed using clinical data from 415 AML patients at MD Anderson Cancer Center and stratified based on hnRNP K protein expression as evaluated by RPPA. To directly evaluate the impact of hnRNP K overexpression in vivo, we created 2 distinct lines of Hnrnpk transgenic mice (HnrnpkTg). Phenotypic differences in the hematologic compartments of these mice were evaluated via flow cytometry, immunohistochemistry, and transplantation assays. Molecular pathways have been evaluated in mice and cell lines using immunoblotting, qRT-PCR, and RNA-immunoprecipitation. The drug JQ1 was used in vitro with both OCI-AML3 cell lines and with primary bone marrow and splenocytes from HnrnpkTg mice. RESULTS/ANTICIPATED RESULTS: FISH analyses demonstrated that a large proportion of AML cases had amplification of HNRNPK that corresponded with upregulation of HNRNPK at the RNA and protein levels. Indeed, patients with high levels of hnRNP K had decreased overall survival compared with those expressing lower hnRNP K levels. In line with these clinical observations, we observed altered myelopoiesis in HnrnpkTg mice. These mice demonstrate increased CD11b+Gr1+ populations in the bone marrow and peripheral blood. Indeed, these mice develop myeloid leukemia, indicated by >20% of circulating white blood cells harboring markers of immature stem cells in conjunction with positive myeloperoxidase staining and blast-appearing morphology. RPPA revealed expression of c-Myc positively correlated with increased hnRNP K levels. In HnrnpkTg mice, c-Myc protein was increased, yet MYC RNA was invariably decreased compared to wildtype. To decipher a mechanism by which this may occur, we demonstrated a post-transcriptional interaction between hnRNP K and c-Myc in vivo. JQ1, a BRD4 inhibitor, that epigenetically decreases c-Myc expression showed preferential activity against myeloid cells expressing high levels of hnRNP K both in vitro and in vivo. DISCUSSION/SIGNIFICANCE OF IMPACT: These preliminary studies demonstrate that hnRNP K overexpression causes myeloid malignancies in both mouse and man. We have determined that c-Myc contributes in part to hnRNP K-mediated leukemogenesis, and that targeting c-Myc may be an effective strategy for hnRNP K-overexpressing AML. We are currently validating other potential targets for interaction with hnRNP K by performing RNA-Seq and hnRNP K immunoprecipitation followed by mass spectrometry. Fortunately, several of our putative targets are druggable—allowing for viable translational outputs to these mechanistic studies.

Objectives/Goals: Increasingly, women and people of color are earning PhDs. However, historically underrepresented (HU) degree seekers often follow a “nontraditional” track, pursuing their degree part time, at an older age, and balancing work and family with their studies. Over half of the U.S. PhD students are part time, a feature correlated with candidate diversity. Methods/Study Population: To address this need, the Advancing Diversity and Equity in Pre-doctoral Trainees (ADEPT) program was developed for part-time HU students who do not meet the requirements of the NIH-funded NRSA TL1 program but who offer relevant work and life experience. The program provides individualized navigation and tailored support based on individual student need and career goals, flexible training opportunities, and intentional connections to established, dedicated, and well-trained mentors throughout the predoctoral journey. To better understand their unique needs, we conducted thematic analysis on the notes taken during monthly meetings to explore the challenges our students face and how ADEPT provides support in navigating these challenges. Results/Anticipated Results: Students pursuing a PhD on a part-time basis while balancing other responsibilities, such as caretaking or a full-time job, bring a unique perspective to their graduate education. 5 ADEPT students described how their background or clinical work experience played a crucial role in their decision to pursue a PhD. Themes from the monthly meeting and mentor meeting notes include the challenges of balancing full-time jobs with school, and how they do not experience the cohort effect that a traditional, full-time PhD student would have as a resource. The students reflected on how an individualized culturally sensitive approach was instrumental to their success. Discussion/Significance of Impact: It was initially believed that part-time PhD students were rare. Despite this misconception, we easily recruited students. Students reported their experiences do not reflect the experiences of their full-time peers and their difficulty establishing a peer group, demonstrating the clear need for ADEPT.

OBJECTIVES/SPECIFIC AIMS: Innovation in healthcare is increasingly dependent on technology and teamwork, requiring effective collaboration between disciplines. Through an intensive team-based competition event, Mount Sinai Health Hackathon 2017, aimed to harness the power of multidisciplinary and transdisciplinary collaboration to foster innovation in the field of cancer. Participants were immersed in an intensive weekend working in teams to develop technology solutions to important problems affecting patients and care providers in the field of cancer. The learning objectives were to enable participants to: Identify cancer-related healthcare problems which lend themselves to technology-based solutions. Delineate key behaviors critical to multidisciplinary team success Identify optimal strategies for communicating in multidisciplinary teams. Engage and inspire participants to apply knowledge of technology to meaningfully impact clinical care and well-being. METHODS/STUDY POPULATION: The Mount Sinai Health Hackathon is an annual 48-hour team-based competition, using a format adapted from guidelines provided by MIT Hacking Medicine. The 2017 event gathered a total of 87 participants (120 registered), representing 17 organizations from as far away as California, with a diverse range of backgrounds in bioinformatics, software and hardware, product design, business, digital health and clinical practice. The overall participation model included: Phase 0: Health Hackathon 101 summer workshops; Phase 1: pre-Hackathon priming activities using online forums Trello and Slack; Phase 2: a 48-hour onsite hackathon to catalyze innovation through problem sharing, solution pitches, team formation and development of prototype solutions; Phase 3: competitive presentations to judges and prize awards; Phase 4: a suite of post-hackathon support to stimulate continued development of innovations. The event sponsored by ConduITS, was also co-sponsored by Persistent Systems, IBM Watson, Tisch Cancer Institute, Sinai AppLab, Sinai Biodesign and other ISMMS Institutes. Mentors circulated throughout the event to support the teams in the technical, clinical, and business development aspects of their solutions. In total, the 14 teams formed during the Hackathon, created innovations ranging from diagnostic devices, networking apps, artificial intelligence tools, and others. The top 3 teams were each awarded $2500 to support their projects’ future development. RESULTS/ANTICIPATED RESULTS: Qualitative and quantitative post-event survey data revealed the Hackathon experience fostered collaborative attitudes and a positive experience for participants, providing insight into the potential benefits of team science. In the post-event survey (n=24) 92% of participants reported that the experience increased their ability to solve problems and 96% made new professional or personal connections. In addition, 96% of respondents would attend future Hackathon events and 75% reported they were likely to continue working on their project after the Hackathon. Qualitative feedback from 1 participant reported it was: “a wonderful event that really highlighted how much interdisciplinary team science can achieve.” Along with intermediate support interactions, including the winning teams participating in a Shark Tank style event with pitches to external entrepreneurs and investors, all teams will be followed up in 6 months time to determine if participants continue to work on projects, file new patents, create new companies, or leverage the new connections made through the Health Hackathon experience. DISCUSSION/SIGNIFICANCE OF IMPACT: Our experience indicates that a Health Hackathon is a compelling and productive forum to bring together students, trainees, faculty, and other stakeholders to explore tech-based solutions to problems in cancer and other areas of biomedicine. It is a valuable tool to foster collaboration and transdisciplinary team science and education. Follow-up analysis will determine to what extent the Mount Sinai Health Hackathon is contributing to an ecosystem that encourages professionals and trainees in healthcare and in technology development to work together to address unmet needs in healthcare with innovative technology solutions.

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: Sexual minority men (SMM) of color are at greater dementia risk than their White and non-SMM counterparts. The purpose of this study is to examine the relative effects of ethnoracial minority status, sexual minority status, and the intersection of both on dementia risk for men in the U.S. using subjective cognitive decline (SCD) as a proxy for dementia. METHODS/STUDY POPULATION: Data will be weighed to represent population estimates from 35 states’ 2019-2022 Behavioral Risk Factor Surveillance System Survey to describe SCD among 4 study groups consisting of SMM and non-SMM who are from minoritized ethnoracial groups (i.e., minoritized ethnoracial gay and bisexual men, minoritized ethnoracial heterosexual men), and White SMM and White non-SMM (i.e., White gay and bisexual men, White heterosexual men) aged ≥45 years. Logistic regressions and adjusted odds ratios will determine SCD prevalences and test for differences between prevalence and demographic characteristics (i.e., education, employment, income, marital status, health coverage, and depression). RESULTS/ANTICIPATED RESULTS: Due to excess chronic stress from belonging to multiple intersecting marginalized identities, we expect that SMM from minoritized ethnoracial groups will have a greater prevalence and higher odds of SCD after accounting for demographic factors when compared to groups that benefit from both “White Privilege” and heterosexism (White non-SMM, White SMM, and minoritized ethnoracial non-SMM). We also expect the odds of SCD to be higher in minoritized ethnoracial SMM when compared to White non-SMM and minoritized ethnoracial non-SMM. The odds of SCD are expected to be higher in White SMM compared to White non-SMM. DISCUSSION/SIGNIFICANCE: This is the first population-based study to apply an intersectional lens to examine dementia risk across the axes of race, sexual orientation, and gender identity. Findings from this study can inform targeted interventions to address the needs and experiences of LGBTQ+ subgroups at risk or living with dementia.

OBJECTIVES/SPECIFIC AIMS: The study aims to develop and test a biocompatible 3D-printed IVRs for the mechanical and release properties of a model drug, β-estradiol, then translate these methods to the target drug, progesterone. The goals include demonstrating decoupling of mechanical and release properties of the rings, release profiles driven by geometry and efficacy in sheep animal models to evaluate device safety. METHODS/STUDY POPULATION: A novel 3D-printing platform, continuous liquid interface production (CLIP), pioneered by Carbon, enables the fabrication of complex designs on a timescale that is amenable to manufacturing. The process utilizes computational-aided design (CAD), specifying shape and geometry, which is recreated via a photopolymerization process. IVRs are fabricated with CLIP using a biocompatible resin at a rate of approximately 15 min. per ring. Rings were fabricated and assessed for the release of a model drug, β-estradiol. The process was then translated to the target drug, progesterone. Rings were evaluated for radial compression and in vitro release in simulated vaginal fluid (SVF). RESULTS/ANTICIPATED RESULTS: Intravaginal rings (IVRs) were designed and fabricated to be geometrically complex in an effort to control release. Ring geometry and subsequent pore size was achieved through the use of unit cells. Several design parameters were explored including unit cell type, size, and band presence in two resins of differing mechanical properties. Through design, a wide range of radial compressive properties were achieved which spanned values covered by commercially available rings. The release of β-estradiol in SVF was found to span 57 – 115 days and resulted in near or complete release of the total loaded drug. Changing the internal geometric design of the ring was found to have minimal influence on the compression properties, thus the mechanical and release characteristics of the rings were largely decoupled. DISCUSSION/SIGNIFICANCE OF IMPACT: This is a novel approach to the design and fabrication of intravaginal rings for the treatment of infertility. The use of CAD and the decoupling of release from mechanical properties allows for us to move away from the one-size one-dose fits all approach to IVRs.
