Published: April 2024

OBJECTIVES/GOALS: This study aimed to characterize urinary exosomal miRNA content in African American adults with diabetic kidney disease. METHODS/STUDY POPULATION: Male and female participants between the ages of 18 and 65 were recruited from the Diabetes Treatment Center and the Nephrology Clinic at the Howard University Hospital. Exosomes were isolated from cleared urine of healthy controls (n=3), type 2 diabetics (n=3), and participants with chronic kidney disease (n=3). The purity and size of isolated microparticles was evaluated using NanoSight technology (30nm to 120nm size range) and western blot analysis for exosome-specific markers (TSG101 and CD81) RESULTS/ANTICIPATED RESULTS: Expression of 5 selected microRNAs, miR-4534, miR-320c, miR-451, miR-362-3p and miR-877-3p were evaluated by qRT-PCR. miR-4534 and miR-451 was increased between healthy controls and the type diabetic group. MiR-320c was increased in the CKD group, in comparison to healthy controls. Conversely, there was no difference in miR-877-5p between the three groups. DISCUSSION/SIGNIFICANCE: These findings will provide insight into the use of circulating miRNAs as early markers of DKD, ultimately creating more effective treatments and preventive measures.

Authors: Crum Kathleen I. , Aloi Joseph , LeFevre Katherine , McCormack Kennedy , Hulvershorn Leslie
Published: April 2024

OBJECTIVES/GOALS: Maternal mental health, such as post-traumatic stress disorder (PTSD), is closely linked to child mental health. PTSD in mothers is associated with their children’s emotional responses. We examined associations between maternal PTSD and child brain function during emotion regulation. METHODS/STUDY POPULATION: Eight children ages 10-12 years, whose mothers had trauma histories, performed the Emotional N-Back task during functional MRI scanning. Mothers and children each reported on their trauma exposure and PTSD symptom severity. BOLD response to fearful faces during the Emotional N-Back was extracted from two specific brain regions of interest, amygdala and anterior cingulate cortex. These regions are involved in emotional response and attentional control, which are processes intrinsic to emotion regulation. An independent samples t-test was conducted on children’s BOLD response to fearful faces, with maternal PTSD symptom severity (high, low) as the independent variable. A parallel analysis was conducted with child PTSD symptom severity (high, low) as the independent variable. RESULTS/ANTICIPATED RESULTS: We found a main effect of maternal PTSD within brain regions of relevance to implicit emotion regulation. Compared to children whose mothers reported low PTSD symptom severity (n=4), children whose mothers reported high PTSD symptom severity (n=4) showed greater responsiveness to fearful faces in anterior cingulate cortex (t=2.04, p=.09,d=1.44) and amygdala (t=2.44, p=.05, d=1.72) at trending significance. A parallel analysis with child PTSD symptom severity showed no differences in brain function by this factor (ps=.55-.61). DISCUSSION/SIGNIFICANCE: Our pilot study is the first, to our knowledge, to examine associations between maternal PTSD and brain function during emotion regulation in their children. This study lays a foundation for future work; our goal is to explore dysfunction in emotion regulation neurocircuitry as one mechanism linking maternal PTSD to their children’s mental health.
25 Evaluating serum copper and kidney function in a cohort of bariatric surgery patients
Authors: McKeon Katherine , Cook Michael , Baker John , LaPenna Kyle , He Hua , Anderson Amanda , Rabito Felicia
Published: April 2024

OBJECTIVES/GOALS: High serum copper (Cu) levels have previously been described in bariatric patients. The kidneys are a target organ for Cu toxic insult but the role of Cu on kidney function (eGFR) is uncertain. This study examines the association between Cu and eGFR in a bariatric population in Southeast Louisiana. METHODS/STUDY POPULATION: Seven hundred fifty patients will be recruited from the Bariatric Center of the University Medical Center in New Orleans. Inclusion criteria include: age ≥ 18 years, clinic visit between June 1, 2018 – May 31st 2024, and having a serum Cu test result. Covariables such as inflammatory markers and hormonal contraception use will be assessed as potential confounders. Blood pressure will be assessed as a potential effect modifier. Data will be obtained from electronic medical records. Two cohorts will be assembled, a pre-surgery cross-sectional cohort and another followed post-surgery. Separate models will be developed stratified by race-ethnicity. RESULTS/ANTICIPATED RESULTS: In a pilot study of bariatric patients 26% had elevated (>155 mcg/dl) serum Cu and pronounced racial differences were noted. Characteristics consisted of a mean BMI of approximately 50 kg/m2; 91% were female and 69% were Black. Black patients had approximately double the prevalence (OR 1.98; 95% CI: 1.15, 3.4) compared to white patients. Due to the dual nature of the kidneys’ involvement in metabolism via excretion and being the target organ for toxic insult, racial differences in exposure, coupled with the disproportionate rates of chronic kidney disease in Black adults, may be an explanation for the association between elevated Cu levels and eGFR in Black adults in this study. DISCUSSION/SIGNIFICANCE: Results from this study will provide insight into the prevalence of Cu and its association with kidney function in a bariatric population. Chronic kidney disease or other forms of renal impairment may result in the need for more conservative guidelines for dietary copper in bariatric medicine.
506 Examining Participant Representation in Atopic Dermatitis Clinical Trials from 2011-2022
Authors: Pacifici Eunjoo , Manrique Kaye Karen , Terteryan Araksi L , Lai Emily
Published: April 2024

OBJECTIVES/GOALS: This study seeks to comprehensively evaluate the extent to which participants in clinical trials (CT) for Atopic Dermatitis (AD) accurately mirror the demographics and characteristics of the broader AD-affected populations. We will achieve this objective by analyzing data from AD CTs spanning the years 2011 to 2022. METHODS/STUDY POPULATION: We examined completed trials for 10 FDA approved treatments for AD, utilizing data sourced fromclinicaltrials.gov [http://clinicaltrials.gov]. In light of the increased number of AD clinical trials over the past decade, we tailored our search parameters to encampass all trials related to approved treatments from 2011-2022. To assess the characteristics of the participant population in these trials, information including inclusion and exclusion criteria, age, location, sex, and disease severity were collected for each trial. Furthermore, race and ethnicity data were also extracted and analyzed. Additionally, comparisons were drawn between trials completed before and after April 2017, when the FDA began requiring that researchers publish race and ethnicity data toclinicaltrials.gov [http://clinicaltrials.gov]. RESULTS/ANTICIPATED RESULTS: Across 67 CTs examined, 45% of trials were restricted to adult patients, 28% were restricted to pediatric patients, and 27% included both. 77% of CTs occurred in urban settings and 23% occurred in rural settings according to the The Economic Research Service definition. 36% of CTs included mild-to-moderate AD patients, and 64% of CTs included moderate-to-severe AD patients. Race distribution of CTs revealed 67% White, 14% Black/African American, 16% Asian, and 3% others. 13% of participants identified as Hispanic or Latino. With further analysis, we will determine whether there is a difference in ethnic distribution between trials completed before and after April 2017, when the FDA started requiring race/ethnicity data to be submitted. DISCUSSION/SIGNIFICANCE: The findings highlight a significant concern in AD CTs: the insufficient representation of Black and Asian populations. The findings emphasize the need for a more inclusive selection process that accurately reflects the diversity of patients. Failing to do so could undermine the assessment of treatment effectiveness in such populations.
511 Analysis of Clinical Outcome Assessments in Clinical Trials for Huntington’s Disease
Authors: Kim James , Pire-Smerkanich Nancy
Published: April 2024

OBJECTIVES/GOALS: Examine the use of Patient-Reported Outcomes (PRO) in Huntington’s Disease (HD) clinical trials (CT) and compare across time and sponsor types. METHODS/STUDY POPULATION: Conduct literature review on 1. background of HD, 2. what symptoms and outcome measures are most important to patients, including the Patient-Focused Drug Development (PFDD) meeting for HD–led by the U.S. Food and Drug Administration (FDA), 3. what outcome measure tools currently exist and what they measure. Utilizing Clinicaltrials.gov, trials for HD were examined to assess the number of trials conducted, what COAs were used, and funding types. Trials were filtered by study type (keep Interventional) and status (filter out suspended, terminated, unknown, and withdrawn). The frequency of COAs will then be mapped based on the symptoms from the PFDD meeting. RESULTS/ANTICIPATED RESULTS: From the PFDD meeting for HD, symptoms that were important to patients include cognitive impairment, depression and anxiety, and motor symptoms. From the 139 interventional studies that were active, complete, recruiting, or not recruiting, 79 studies were conducted by Industry, 3 by NIH, 93 by Other (Academia/Community Organizations), and 1 by a U.S. Federal Agency (other than NIH). One of the most commonly used COA is the Unified Huntington’s Disease Rating Scale (UHDRS), which includes a motor, cognitive, and behavior assessment, and an assessment on functional capacity and independence. Of the 27 out of 139 trials analyzed to date, there were a total of 37 COAs. DISCUSSION/SIGNIFICANCE: The widespread use of UHDRS can be attributed to its standardization in 1999. It captures the symptoms of HD that are most important to patients. Because UHDRS is not sensitive to any one symptom, other COAs have been developed which focus on unique aspects of HD and allow for its earlier detection.

Published: April 2024

OBJECTIVES/GOALS: The FDA allows physicians to request clinical use of investigational drugs, biologics, and devices for patients with no satisfactory treatment options through a pathway called Expanded Access (EA). TEAMSS (Transforming Expanded Access to Maximize Support and Study) sought to examine single-patient cases to better characterize these patients. METHODS/STUDY POPULATION: We prospectively collected data on requests for single-patient EA at any one of the four collaborating TEAMSS institutions (Duke University, University of Rochester, University of Michigan, and University of Texas Southwestern) between September 1, 2021 and February 28, 2023. Regulatory and health records were reviewed for past cases that occurred between June 1, 2018 and August 31, 2021. Descriptive statistics were performed on data from the submission process, the patient demographics, the indication for treatment, and patient health status over time. RESULTS/ANTICIPATED RESULTS: The patient population was representative with respect to the largest racial groups (69.3% White / 13.0% Black or African American) and legal sex (51.3% male / 48.7% female). All ages were represented, with overrepresentation of those 60-70 years old (16.8%) and under 10 (14.8%). Patients were most often treated for infectious diseases (44.2%) or oncologic conditions (39.0%). Those who received more than one dose stayed on treatment for 76 days (median) and up to 1427 days (maximum). At the end of study, 53.9% had completed treatment as planned, moved to commercial product, or continued treatment. Death, disease progression, or failure to respond occurred for 31.9% of patients. DISCUSSION/SIGNIFICANCE: The population that receives Expanded access treatments is heterogeneous in both demographics and medical conditions. Some successful treatments are continued for years. Many patients complete their treatment, and a minority experience death or disease progression during treatment.

Published: April 2024

OBJECTIVES/GOALS: To establish and develop a high-level, dynamic, and self-sustainable Translational Science – research center in Colombia that promotes and articulates collaborative participation among different disciplines at Universidad de La Sabana to generate impactful solutions in health to transfer the knowledge to the local community. METHODS/STUDY POPULATION: With the support of core units of the University, internal funding was given for the establishment of the Research Center. An internal call was performed for recruiting researchers for multiple disciplines interested in joining the UCTS. After the researchers were selected, training of the research community in translational science and funding acquisition was performed towards the objective of interdisciplinary projects with impact in the local community. Project management strategies have been used for the follow-up of the advancements of the implementation of the UCTS. Operational structure and business plan for future self-sustainability are being designed. UCTS is proposed as an articulating party among different actors in clinics, research, and industry, for science and funding management. RESULTS/ANTICIPATED RESULTS: As an starting point, 8 research groups of different disciplines of the University have been integrated with the UCTS, increasing the research capacity in translational science. Internal administrative processes have been articulated within the institution and unified processes for international grants applications have been established in order to optimize the funding acquisition and management. Training programs for the research community, and community engagement activities have been offered as well. Networking relationships have been strengthened among the researchers enhancing international collaborations. Novel research projects are being designed towards real solutions in health for the local community, promoting the transference of knowledge from the benchside to the community. DISCUSSION/SIGNIFICANCE: The implementation of the UCTS led to the integration of disciplines within the University, towards new research projects with common interests for the local community. It has been an enriched experience using the project management approach, fulfilling a huge milestone for the University, aligned with the internal strategic priorities
26 Avoiding Death From Stimulant Toxicity: Resiliency Among People Who Use Stimulants
Authors: Anderson Nigel Parker , Coffin Phillip , McMahan Vanessa
Published: April 2024

OBJECTIVES/GOALS: The project investigates the role that resiliency may play within individual, interpersonal, social, and structural contexts in protecting against acute lethal stimulant (meth/amphetamine or cocaine) toxicity. Identifying preventative factors is crucial in developing and implementing risk reduction strategies for people who use stimulants. METHODS/STUDY POPULATION: This is a qualitative study involving in-depth interviews via questionnaire assessing resiliency factors among persons living in San Francisco who have used primarily either meth/amphetamine or cocaine for at least 5 years. The interviews will be coded for salient and recurrent themes and analyzed for code frequency, cooccurrences, clustering of themes and representative excerpts to highlight emergent themes as well as stressors and resilience factors at multiple levels. We aim to assess for substance use patterns, multiple domains of resiliency, medical and psychiatric complaints, and risk reduction strategies. We will recruit participants to match recent decedents from acute stimulant toxicity in various domains including salient demographic information and neighborhood characteristics. RESULTS/ANTICIPATED RESULTS: The anticipated results include a qualitative interview guide for living persons using stimulants in San Francisco to be used to gain insight into the community, illustrate participants’ substance use practices, and allow for better characterization of several discrete resiliency factors that have protected the participants and other community members from suffering lethal stimulant toxicity. We expect to identify individual components (e.g. use patterns, use of harm reduction supplies), interpersonal/social factors (e.g. drug using network, friendships, community connection), and structural influences (e.g. access to care, safe use sites, house and economic stability) that all play a role in resiliency against lethal stimulant toxicity. DISCUSSION/SIGNIFICANCE: Stimulant use is common, along with rising deaths involving stimulants in urban counties and in smaller rural/non-metro counties which are disproportionately affected, posing a public health challenge. We will find discrete, modifiable risk and resiliency factors that can be manipulated to minimize the chances of outcomes like overdose and death.
517 The Development of New Institutional Policies on Mitigating Unacceptable Behavior and Managing Disruptive Research Participants
Authors: Kwon Simona , Bunting Amanda , Panageas Helen , Margiotta Joan , Diaz Kimberly , Laynor Gregory , Holahan James , Andersen SUsan
Published: April 2024

OBJECTIVES/GOALS: In a 2022 NASEM Report, “… successful inclusion of underrepresented populations in research is investing in diverse research teams to enhance congruence and to optimize recruitment and retention success.” Thus, academic research institutions must provide safe, respectful and inclusive work environments to support diverse research teams. METHODS/STUDY POPULATION: Resources, policies and protocols related to disruptive research participants have not been well articulated at our institution. Given this dearth of information, we launched a new initiative across our CTSA, IRB, Office of General Counsel and Department of Population Health. The multipronged approach includes: 1) Conduct a scoping review of published and gray literature to identify best practices, trainings and resources to mitigate discrimination, harassment of research team members; 2) Co-develop new institutional policies and procedures to ensure safety and respect for both research staff and participants; 3) Develop an online training on research team field and workplace safety; and 4) Widely disseminate policies and resources to address the overall gap in academic research. RESULTS/ANTICIPATED RESULTS: Our ongoing scoping review has shown that here is an overall lack of information on bias, discrimination and harassment perpetrated by research participants towards research teams. Based on our activities, new Human Research Protection policies were launched. These include defining what disruptive participant behavior in research is, the introduction of a Statement on the Conduct of Participants in Research Studies, and steps study teams may implement to manage disruptive behavior initiated by a research participate. Next steps include the development of training resources for study teams on the new policies and to introduce de-escalation and situational awareness strategies and trainings. DISCUSSION/SIGNIFICANCE: As research teams become increasingly diverse, there is a need to better support them and ensure that the research field and work settings are safe, inclusive environments with articulated policies that mitigate/prevent discrimination, bias and harassment perpetrated by study participants.
519 Strategic Reinvestment of Sponsored Trials Residuals for Research Portfolio Development
Authors: Friedland David R. , Nebel Justin , Ward Doriel , Shaker Reza
Published: April 2024

OBJECTIVES/GOALS: Academic research is often viewed as a necessary core mission but a financial loss requiring central or clinical funds support. We present cases as evidence of sustaining academic unit research endeavors through strategic planning and reinvestment of sponsored clinical trials residuals. METHODS/STUDY POPULATION: Successful endeavors are presented that demonstrate strategic reinvestment of clinical trials residuals to develop robust academic self-sustaining research programs. A multi-year strategic plan was developed leveraging residuals from sponsored clinical trials to build an academic research infrastructure supporting extramural grant applications, pilot studies, pre- and post-award management, equipment investment, and faculty incentives. RESULTS/ANTICIPATED RESULTS: Example 1, pooling four existing department clinical trials generated yearly profits that expanded clinical trials capacity and used residuals to support a grant coordinator. Over 7 years, trial volume increased to near 50, revenue increased to $2.5 million annually, staffing increased to 20 FTEs, and extramural grant applications increased from 16 to 50. Example 2 started with a department with no infrastructure. Central support was leveraged for 6-months to support a coordinator to initiate a clinical trials program. The initial investment was offset by trials earnings by year 2, breaking even financially, while establishing a nascent yet robust infrastructure to build autonomously without additional central funding requests. DISCUSSION/SIGNIFICANCE: Utilizing sponsored clinical trials as a strategic investment fund, academic units can realize fiscally responsible expansion of research activities and national recognition through acquisition of extramural funding and investigator-initiated investigations.
521 Bringing UCSF Research Resources to Community Health Systems: CTSI Research Infrastructure Network (RIN)
Authors: Herraiz Laurie , Potter Michael
Published: April 2024

OBJECTIVES/GOALS: The CTSI Research Infrastructure Network (RIN) expands CTSI’s reach into the regional health systems to provide our services to a broad and diverse translational science community. We create and support research collaborations that span multiple geographies and patient populations and serve as a bridge between the affiliate sites and CTSI programs. METHODS/STUDY POPULATION: We conducted needs assessments at each site (n=6) via in-depth, semi-structured interviews with key stakeholders. Informants (n=40) included investigators, study personnel, and research administrators. Investigators were selected across a variety of departments and career stages. Interview transcripts and notes were analyzed using matrix-based qualitative methods to identify both the common and unique research infrastructure needs of each site. Individualized support plans were shared with each site and a comprehensive summary report was presented to CTSI leadership. RIN met with UCSF’s Comprehensive Cancer Center, which conducts clinical trials at 2 sites, to coordinator our effort and services. When possible, RIN addressed service requests in real time that arose during interviews. RESULTS/ANTICIPATED RESULTS: We identified heterogeneous needs across multiple sites. However, among the community health systems with non-academic clinicians, there were common needs for research training, consultations in biostatistics/study design, and finding academic collaborators. The needs of sites with UCSF academic faculty differed from those of community sites and mainly included improved awareness and access to CTSI programs, ease of use of data extraction services, training programs, and assistance with regulatory approvals. Site needs are best addressed with individual plans created with CTSI Program leaders. A developing governance structure will include representation on a CTSI advisory committee and an annual conference to facilitate the sharing of best practices and foster collaboration across member sites. DISCUSSION/SIGNIFICANCE: Providing an individualized, site-specific approach to expanding CTSI services to regional health systems, will increase research collaborations across Northern California through building relationships, addressing unique infrastructure needs and sharing best practices throughout the network.
27 Racial-Ethnic Differences in Antipsychotic Initiation Among Youth with Diagnosed ADHD, Depression, or Conduct Disorder
Authors: Sepe-Forrest Linnea , Meraz Richard , Adams Sydney , D’Onofrio Brian M. , Quinn Patrick D.
Published: April 2024

OBJECTIVES/GOALS: This study examined racial-ethnic differences in antipsychotic initiation within psychiatric diagnostic groups. This is a follow-up to our prior work, which reported that, overall, youth from minority backgrounds had 30-65% lower odds of initiating antipsychotics compared to White youth. METHODS/STUDY POPULATION: This study used 2009-2021 data from Optum’s® Clinformatics® Data Mart, a database containing longitudinal patient information from nationwide commercial insurance claims. We created three separate samples of antipsychotic users and matched non-user controls between the ages of 6-17 years old. These groups contained individuals with clinically diagnosed ADHD, conduct disorder, and depressive disorder, respectively. We used conditional logistic regression to estimate the odds of antipsychotic initiation based on race-ethnicity within each diagnostic group. RESULTS/ANTICIPATED RESULTS: There were no racial-ethnic differences in the odds of antipsychotic initiation among youth diagnosed with ADHD. Among youth with depression diagnoses, Asian youth had 19% lower odds of initiating antipsychotics and Hispanic youth had 11% lower odds compared with White youth. Similar results were observed for conduct disorders, with Asian and Black youth having approximately 10% lower odds of initiating antipsychotic treatment and Hispanic youth having 18% lower odds relative to White youth. DISCUSSION/SIGNIFICANCE: Previously observed lower rates of antipsychotic initiation among racial-ethnic minority groups may be at least partially due to factors leading to disparities in diagnosis. Further research is needed to evaluate factors that may lead to differential antipsychotic use, as the disparities may occur upstream of receiving clinical diagnoses.
528 Midwest Translational Science (MTS): Building a regional CTSA community
Authors: Cielo Karen , Hays Toddie (Patricia) , Leep Sherry
Published: April 2024

OBJECTIVES/GOALS: Our vision is to build community amongst the Midwest CTSAs, harnessing our collective expertise to collaborate on translational science challenges and meet the needs of our region. We aim to create opportunities to network, share ideas, brainstorm solutions, address translational science topics, and achieve a range of deliverables. METHODS/STUDY POPULATION: Three individuals from the Chicago CTSAs (NUCATs, CCTS, and ITM) had been networking for a year and desired to increase opportunities to collaborate amongst other CTSAs. We developed an initial vision for a new group that would extend across the region, and we invited the TIN POCs from 16 Midwest CTSAs to join. In September, 2022, the group was launched with 20 members from 12 CTSAs. We hosted 12 monthly meetings via Zoom to discuss various topics (i.e., staffing, career training, e-consent, research design, and recruitment tools) via round tables or presentations. We developed a Google Sites website with resources, a discussion forum, and a group calendar. We solicited feedback via survey and follow-up discussion (i.e., most valuable about the group and what can be improved). RESULTS/ANTICIPATED RESULTS: During the past year, our membership grew to more than 30 participants, representing 16 CTSAs in nine Midwest states (IL, IA, IN, MI, MN, MO, KT, OH, WI). We engaged a total of 45 individuals at our meetings, with an average of 11 participants per meeting. Our discussions were lively and stimulated additional conversations, requests for guidance, sharing resources, etc., beyond the meetings. Feedback from the group was overwhelmingly positive. Members found many aspects of the group to be valuable (i.e., learning initiatives, processes, and best practices at other CTSAs) and provided practical suggestions for improvement (i.e., themes across a quarter or year). Members expressed interest in additional collaborations such as subcommittees, papers, and other initiatives. DISCUSSION/SIGNIFICANCE: We created a regional CTSA community that is very enthusiastic to convene, share innovations developed at their CTSA hubs, and assist one other. Future directions include an in-person retreat in the spring. Our approach can serve as a potential roadmap for developing regional CTSA collaborative groups across the nation.

Published: April 2024

OBJECTIVES/GOALS: An environmental scansoughtto understand research processes, areas for improvement, and opportunities for collaborative quality improvement (QI)across the Northwest Participant and Clinical Interactions Network (NW PCI). METHODS/STUDY POPULATION: NW PCI site champions were invited for semi-structured single and group Zoom-based interviews. Interviewers asked participants about local research processes, strengths and weaknesses, existing infrastructure to support QI, and interest in collaborative QI across the Network. Audio transcripts were coded using Dedoose and analyzed with deductive and inductive coding. RESULTS/ANTICIPATED RESULTS: Between February and April 2023, 10 interviews collected data from 7 research decision makers and 7 staff members across 7 sites. Most participants (n=13, 92%) agreed the diagram shown during the interview was representative of the local process. Organizations consistently identified strengths and weaknesses within the domains of study start-up, recruitment, budgets, and compliance. QI infrastructure was inconsistent (n=5, 36%) and all (n=14, 100%) saw potential for success in multisite QI initiatives to enhance efficiency. DISCUSSION/SIGNIFICANCE: NW PCI sites use similar processes, share common strengths and weaknesses, and universally reported interest in collaborating on QI. Study startup was reported as both a strength and weakness within the same organization, requiring unpacking of key elements before pursuing QI initiatives.
531 Transforming a Pilot Grant Program to Advance Clinical & Translational Science
Authors: LaPensee Beth , Cantrell Mark , Ahrens Lisa , Downey Brad , Samuels Elias , Somers Emily
Published: April 2024

OBJECTIVES/GOALS: A new mandate for Clinical & Translational Science Award (CTSA) Programs is for pilot grant funding to support clinical and translational science (CTS) projects that study challenges in the translational research pipeline. This pivot requires new structures and supports to help investigators design and implement high-quality CTS projects. METHODS/STUDY POPULATION: The Michigan Institute for Clinical & Health Research (MICHR) at the University of Michigan (U-M) has launched two rounds of pilot funding since March 2023. Faculty and staff across U-M’s three campuses, community members, and those at collaborating institutions and hospitals were eligible to apply. New pre-award supports included a CTS project framework; a recorded webinar that educated about CTS and the funding opportunity; office hours to provide tailored project feedback; a letter of intent to screen for alignment with CTS; and reviewer training for academic and community reviewers. Funded projects operate like 'mini cooperative agreements”, with MICHR experts partnering with awardees to refine evaluation plans, prepare work products, advise on dissemination, and navigate emergent challenges. RESULTS/ANTICIPATED RESULTS: The first round of funding was launched in the absence of pre-award supports; ten applications we received from faculty proposing translational research rather than CTS. We quickly re-released the FOA, expanding eligibility to staff. We received nine applications, ultimately funding four staff and one faculty studying operational challenges in translation and helping them create robust evaluation plans. We piloted the pre-award supports in our second round, with 40 individuals viewing our webinar and 11 attending office hours. Those who watched the webinar before attending office hours better understood how to embed CTS questions within their programs of research. We recently received 19 letters of intent, addressing both operational and scientific challenges, with 16 eligible to submit applications. DISCUSSION/SIGNIFICANCE: Education and personalized feedback seem to elicit a higher yield of CTS projects. Staff are already adept at solving operational challenges, so the pre-award supports were most critical for faculty accustomed to writing traditional translational research proposals. Staff have most benefited from guidance in evaluation and dissemination.
532 Application of the CTME Maturity Model in a CTSA Hub: An Initiative to Improve Clinical Research Operations
Authors: Subramain Maran , Sprenger Kimberly , O’Connell-Moore Debra , Jones-Bitterman Cena , Knosp Boyd M.
Published: April 2024

OBJECTIVES/GOALS: The CTSA consortium’s Informatics Enterprise Committee has developed a maturity assessment model for Clinical Trial Management Ecosystems (CTME). This poster will show the improvements achieved using this model at the University of Iowa as well as guidance on how to apply it at other CTSA hubs. METHODS/STUDY POPULATION: The CTME maturity model consists of 11 categories including, study management; regulatory; financial; and reporting. Each category has 3 subcategories: standardization; complexity; and monitoring, while each subcategory is comprised of 1 to 5 maturity statements: initial; developing; aspiring; capable; and efficient. The maturity assessment team at Iowa—comprised of key personnel from clinical research and compliance, accounting, and administration—have used the CTME maturity model to assess Iowa’s research performance across the 11 categories. The initial maturity ratings for each category revealed any gaps in research operations, which led to developing strategies to address the gaps. RESULTS/ANTICIPATED RESULTS: The assessment team initiated a CTME maturity planning project—holding regular meetings to review Iowa’s CTME research maturity and plan changes to improve our CTME maturity ratings. This analysis is done at the statement level to minimize the scope of actions needed and keep resource loads for improvements low. Proposed improvements are assigned to a team member who serves as an “accountability leader.” Such leaders develop action plans aimed at increasing maturity at least one level. The leaders are responsible for acquiring the resources to carry out the plan. Each action plan identifies qualifiers reviewed by the team to confirm that the maturity level has been met. DISCUSSION/SIGNIFICANCE: The CTME maturity model has been shown to be effective in identifying gaps in organizational operations at the University of Iowa, where it has led to incremental steps to improve clinical research operations. The utilization of the model at other CTSA hubs will be discussed at this session.
534 Forming a Translational Operations Group: Bridging the Gap to Enhance CTSA Hub Operational Efficiencies
Authors: Helm Shirley , Harris Lauren D. , DiazGranados Deborah
Published: April 2024

OBJECTIVES/GOALS: CTSA Hubs represent complex centers where teams work to meet multiple goals of the CTSA grant. An existing challenge is to work collaboratively across teams. To address this challenge, a Translational Operations Group (TOG) was established. Results show enhanced intra-hub collaboration and communication while reducing inefficiencies. METHODS/STUDY POPULATION: The TOG is composed of all CTSA hub module program managers who are charged with operationalizing vision into reality. The TOG was formed in 2021 as a mechanism to integrate new team members, provide connection, and improve cross-core awareness and collaboration. Leveraging team science principles, a team charter was developed outlining specific TOG aims and objectives. Collectively, shared goals were identified with establishment of group norms, effective communication pathways, shared resources and knowledge and meeting cadence. Leadership of the group rotates among the TOG members annually further engaging all TOG members. Pre and Post (one year) surveys were developed and provided to TOG members to gauge TOG effectiveness and perceptions of TOG members. RESULTS/ANTICIPATED RESULTS: Survey results demonstrate the effectiveness of the TOG concept in promoting core/module awareness and goals, intra-core/module interconnectedness, and forming connections and integration into the CTSA hub ecosystem. Psycho-social questions demonstrated an increase in organizational self-esteem within the pre to post survey period in relation to the specific TOG member’s core/module and the CTSA hub as a whole. DISCUSSION/SIGNIFICANCE: Formation of a TOG has been successful within a virtual environment where connection is challenging. Integration of members to the operational activities is critical to foster a positive work environment, reduce silo effects, and provide a space for sharing resources and knowledge. Annual reflection of priorities contribute to the ongoing success.

OBJECTIVES/GOALS: Health care accounts for an estimated 10% of U.S. greenhouse gas (GHG) emissions. Concerted efforts to decrease waste are needed including critical appraisal of single use items. The purpose of this study was to conduct life cycle analyses (LCA) of a pediatric single use laryngoscope to inform environmental impact and identify targets to reduce waste. METHODS/STUDY POPULATION: LCA was used to quantify the environmental impact of a single use pediatric laryngoscope. LCA is an industry standard measure of energy consumption, water consumption, and GHG emissions encompassing a “cradle-to-grave” assessment. The GREET model (Greenhouse gases, Regulated Emissions and Energy use in Technologies) and Open LCA model were used as sources for product/raw material data. Separate analysis was completed for the battery powering the light emitting diode (LED) lights. RESULTS/ANTICIPATED RESULTS: The LCA revealed 598.2 g of CO2 equivalents for the 121g single use pediatric laryngoscope. There were an estimated 26,849 cases that used single use laryngoscope last year at our free-standing children’s hospital resulting in 16.1 metric tons of CO2 equivalents. This is equivalent to 41,273 miles driven by an average gasoline powered vehicle. The 1.5 V battery was the highest contributor to the laryngoscope’s GHG emissions. While the battery has an estimated 2,800 hours of life, single use laryngoscopes are reported in the literature as being used for only an average of 30 seconds to 2 minutes. DISCUSSION/SIGNIFICANCE: Single use laryngoscopes are high contributors to GHGs. Specifically, the batteries contained in the laryngoscopes are wasteful and challenging to remove and recycle. Future efforts to decrease waste in the OR should target use of similar items that have reusable battery components to improve environmental sustainability.

OBJECTIVES/GOALS: Investigators have an ethical obligation to return study results back to participants in a timely and layperson-friendly manner, but most do not. This lack of communication can erode trust in the research enterprise. One solution to this issue is Plain Language Summaries (PLS). METHODS/STUDY POPULATION: We investigated and collected best practices for PLS and results dissemination as part of formative research for a pilot PLS project. This pilot was used to inform the development of our own PLS resources, which we will share broadly with other CTSAs. We employed a two-part system for analysis. First, we examined extant PLS resources from five major, publicly accessible sources spanning academia, government, publishing, and nonprofits for themes and best practices. Then, we examined actual PLS from each source and collected more specific feedback. We examined PLS structure, length, inclusion of graphics, multiple language availability, readability, and potential for improvement. RESULTS/ANTICIPATED RESULTS: Guidance sources recommended that PLS have logical and organized structures, and included essential trial information (e.g., study drug, adverse events). Suggestions for length varied widely, from 250 words to 15 pages. Guidance also recommended the use of media, including infographics, audio, and video. Only pharma guidance recommended multilingual PLS. Actual PLS included many common trial elements, including study purpose, treatment description, results, and adverse events. PLS in our analyses were 10-12 pages, and contained many infographics, including flow charts of study phases, visual explanations of treatment and participant demographics, and adverse event tables. None were multilingual, and most were readable at the 7th grade level, although one used undergraduate-level language. DISCUSSION/SIGNIFICANCE: General guidance was similar across sources. In our analyses of PLS, we found novel recommendations, such as including auditory pronunciation guides, and personalized thank you letters to participants. In future research, we recommend focusing on novel dissemination methods such as short interactive videos and patient-actor testimonials.

OBJECTIVES/GOALS: This work aims to explore how citizen science serves as a transformative frame work to bridge scientific knowledge, focusing on its potential to enhance transdisciplinary learning in artificial intelligence (AI) biomedical and clinical sciences by facilitating near-peer mentoring. METHODS/STUDY POPULATION: Our group of eight friends comprise a multicultural and multidisciplinary cohort including students from the USA, Philippines, Indonesia, and Guatemala pursuing PhD degrees in electrical and computer engineering, epidemiology, physics, and MD, PharmD, and DMD degrees. We engage in shared online courses, collaborative projects, and abstract submissions. Employing our collective knowledge, we design interactive learning experiences, support each other’s initiatives, and collaboratively develop lectures and presentations. We in tend to expand collaborations in biomedical AI education while fostering principles of experiential and collaborativelearning, constructivism, and authentic inquiry. RESULTS/ANTICIPATED RESULTS: Our recent successes include submittedconference abstracts on data science and AI education in pharmacy and the facilitation of a guest lecture in health informatics. Additionally, we are currently collaborating on seven biomedical machine learning projects in radio frequency engineering, aiming for conference submissions. Moving forward, our goal is to expand our group, support the formation of similar communities, and promote data science and AI literacy in biomedical and clinical contexts. We aspire to extend this knowledge to families, classmates, and eventually patients, facilitating a broader understanding of the role of AI in healthcare. DISCUSSION/SIGNIFICANCE: We believe diverse expertise and pedagogical theories can help demonstrate the potential of citizen science to democratize scientific experience. By nurturing collaborative networks our efforts aim to bridge gaps between disciplines and enhance the broader public’s understanding of AI in healthcare.

OBJECTIVES/GOALS: Hypertension is a major risk factor for coronavirus disease 2019 (COVID-19) severity. Our goal was to determine if hypertension worsens lung pathology induced by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in hamsters. METHODS/STUDY POPULATION: Male hamsters (7-8 weeks old) were infused with angiotensin II (AII; 200 ng/kg/min via osmotic minipump) for 4 weeks to induce hypertension. During the last week of the infusion, the hamsters were inoculated intranasally with vehicle (V) or SARS-CoV-2 (S; 1 x 105 plaque forming units/ml). Half of the hamsters were sacrificed 1 day post-inoculation (dpi-1) and the other half on dpi-6. Two scoring systems were applied to lung tissue sections stained with hematoxylin and eosin to determine the degree and severity of lung pathology: the first system assessed all pertinent alterations in the lungs, while the second system only assessed the pathology related to the pulmonary vasculature. Lung histopathology scores were calculated as the sum of the airway and lung alveolar scores in arbitrary units (AU). RESULTS/ANTICIPATED RESULTS: Studies revealed that the SARS-CoV-2-infected hamsters exhibited a 76-fold higher total airway score compared to vehicle controls [(AU): V, 0.25 ± 0.1; S, 19.00 ±1.35; p<0.05; n=4]. Total lung alveolar scores (27-fold) [(AU): V, 0.30 ± 0.11; S, 8.0 ± 4.1; p<0.05; n=4] and total vascular scores (17-fold) [(AU): V, 0.35 ± 0.2; S, 6.0 ±1.4; p<0.05; n=4] were also markedly higher compared to controls on dpi-1. AII increased blood pressure, which was sustained through the 4-week infusion period. Under these conditions, body weight slightly dropped by 4.5%. Ongoing studies are assessing the effect of hypertension on the % of airway, alveoli and vessels affected, airway and alveolar severity, and bronchiolar epithelial and type II pneumocyte hyperplasia. DISCUSSION/SIGNIFICANCE: Establishing the hypertensive hamster as a small animal model of COVID-19 will facilitate investigations into why preexisting hypertension is a risk factor for disease severity. These studies could lead to the development of novel therapeuticsfor treating COVID-19 patients with hypertension.
