OBJECTIVES/GOALS: Fragile X-associated tremor/ataxia syndrome (FXTAS) is a devastating rare neurological disorder that negatively impacts movement and cognition. To date, there are no effective pharmacological treatments for FXTAS. Our goal was to develop a cell culture model of FXTAS to investigate promising therapeutics. METHODS/STUDY POPULATION: To establish mitochondrial dysfunction, normal human cell lines and human-induced pluripotent cells were treated with multiple concentrations of glucose/ glucose oxidase (GluOx) at 2,12, and 24 hour time points to induce varying intensities of oxidative stress. The degrees of oxidative stress were measured by apoptosis and mitochondrial reactive oxygen species (ROS) production. Curcumin and MSKE compounds effective against oxidative damage in mitochondria were used to rescue glucose oxidase-induced oxidative damage in both cell lines. To test the ability of these drugs to restore mitochondrial health, cell viability and cellular superoxide production were assessed by propidium iodide and the MitoSox fluorescence assay, respectively. RESULTS/ANTICIPATED RESULTS: We anticipated that GluOx at varying concentrations and time points would proportionally increase levels of apoptosis and mitochondrial ROS, reflective of mitochondrial damage, with the most severe dysfunction occurring at a dose of 25 nM and the longest duration of 24-hr exposure. Administration of MSKE in concentrations ranging from 10-8 to 10-5 M in half log increments, did not reverse the oxidative defects induced in the cell lines. However, curcumin concentrations increased cell viability at the 2, 12, and 24 hour time period. Results indicate that the research design should be modified by increasing the concentration of both glucose and MSKE to provide a reliable test of the hypothesis. DISCUSSION/SIGNIFICANCE: These studies illustrate the usefulness of this in vitro model to test novel therapeutics in neuronal FXTAS models and expand the discovery of mitochondrial markers for the syndrome.

OBJECTIVES/GOALS: The Rockefeller University CCTS, Clinical Directors Network (CDN), and Carter Burden Network (CBN) received a DHHS-Administration for Community Living Nutrition Innovation grant to test whether implementation of DASH-concordant meals and a program to enhance self-efficacy, could lower blood pressure among seniors aging in place. METHODS/STUDY POPULATION: CEnR-Nav model to engage stakeholders, enroll seniors age >60 yr., eating 4 meals a week at 2 CBN congregate meal sites; Advisory Committee to facilitate dissemination; menus aligned with Dietary Approaches to Stop Hypertension (DASH) and New York City Department for the Aging (DFTA) nutritional guidelines; interactive sessions for education (nutrition, blood pressure, medication adherence); Omron 10 home BP devices for daily home monitoring. Plate Waste and Meal Satisfaction (Likert scale) to assess taste preference and cost impact. Outcomes: Primary: Change in Systolic BP at Month 1; change in percent with controlled blood pressure. Secondary: change in validated measures of cognitive (e.g. SF-12, PHQ-2), behavioral (Home BP monitoring), nutritional (food frequency) variables, satisfaction, costs. RESULTS/ANTICIPATED RESULTS: Menu alignment required multiple iterations. Plate Waste and Menu Satisfaction tools were developed. Site 1 enrollment began June 2019; educational sessions and home BP monitors and training were provided. Baseline mean blood pressure (Site 1) was 138/79 +20.5; (range: 7% hypertensive crisis, 36% stage 2 hypertension, 22% stage 1 hypertension, 22% elevated, and 13% normal). DASH-aligned meals began October 2019; Meal satisfaction declined briefly, chefs adjusted menus, and meal satisfaction rose to pre-intervention levels. Site 2 enrollment is ongoing; dietary intervention will start in 2020. Primary outcome data (change in BP) will be complete in March 2020. Secondary outcome data on social and behavioral impact of the interventions will also be presented. DISCUSSION/SIGNIFICANCE OF IMPACT: We leveraged our community-academic research partnership to conduct research addressing uncontrolled hypertension, an urgent unmet health need among seniors. The DASH Implementation Study can inform the broader aging services and healthcare community of the potential for congregate nutrition programs to improve cardiovascular health outcomes.

OBJECTIVES/SPECIFIC AIMS: The Wake Forest Clinical and Translational Science Institute (CTSI) put in place a KL2 program in 2007 and introduced an 18-month Translational Research Academy (TRA) in 2010. The TRA provides education and leadership development training, research support services, mentoring, and networking opportunities to 15-20 early-career clinical and translational researchers, including those receiving KL2 awards. The KL2 and TRA programs make up the Mentored-Career Development Core that is administered by the Wake Forest CTSA Education Program. Over the years, the program administrators have collected feedback from the graduates on what they liked and did not like about the programs. However, a comprehensive evaluation to understand the impact of the trainings on helping scholars advance their research and their research careers was not conducted. The purpose of this evaluation was to assess if and how the KL2 and TRA programs are helping scholars advance their research and career in research. METHODS/STUDY POPULATION: Semi-structured phone interviews were conducted with 11 selected CTSI scholars from both KL2 and TRA programs. The interviews focused on 4 key areas: expectations coming into the program, role the program played in their career development over time, what else could/should have program done to support them and their research, and which of the other CTSI services were valuable in their career development. RESULTS/ANTICIPATED RESULTS: Even though scholars joined the program as an early-career researcher, the amount of experience in research they had varied and so did their areas of interest. The participants in the program also included both clinician and basic researchers. Scholars came into the program with different level of expectations and drive to use this program as a platform to lift their research careers. The conversations during these interviews gave an insight on career trajectories that the scholars have taken before and after joining the academy. For example, among the scholars that had graduated from the programs, 5 of the 6 had received a career development award, all 6 had their own grants to support their research, 3 had received professional promotions, and all 6 have an administrative leadership role they play, in addition to focusing on their research career. The information on where the scholars were at the beginning and the pathway they have taken to get to where they are now allowed us to better understand what aspects of the program was most valuable. The scholars noted that sessions around grant writing and developing specific aims were very helpful. Among the services provided, having a grant editor support was something that everyone noted as the most important service to them, even after leaving the program. DISCUSSION/SIGNIFICANCE OF IMPACT: The impact of the interviews and candid feedback provided by the scholars have been immensely valuable to program administrators to really understand the impact the program (and which components specifically) is having for the scholars. Looking at the career trajectories of the scholars, it was noted that scholars coming in to the academy with some experience doing research and ability to continue engaging in research benefited the most from what the program had to offer. Scholars that were still very early in their research career gained knowledge but were not always able to apply it because they were not working towards a grant at the time. Using the data on career trajectories, recommendations for improving the program, and other CTSI services that were most valuable, the program administrators decided to redesign the curriculum. The new version of the program is now tailored for scholars who have research experience and are working towards a career development grant such as a K or R. This will allow them to have a curriculum that is more intense and hands-on with an expectation that the scholars will submit the application towards the end of the program. A separate program is being developed for early-career researchers who are still setting their foot into t field to provide them basic research competencies through ad hoc courses and seminars.

OBJECTIVES/GOALS: The COVID-19 pandemic disrupted established social support networks (faith-based, community, family, friends), resulting in unprecedented health-related, financial, and employment challenges among African Americans (AAs). This study explores the psychosocial influences of the pandemic on the health and wellness of AAs. METHODS/STUDY POPULATION: The FAITH! (Fostering African-American Improvement in Total Health!) Program, an academic-community partnership with AA churches, shifted focus to COVID-19 prevention in AA communities. Funded by the Mayo Clinic Center for Clinical and Translation Sciences, this cross-sectional study recruited AA adults from FAITH!-affiliated churches and social media to complete a survey exploring the personal impact of the pandemic from hardships (e.g., food and housing insecurity, paying utilities) on healthy lifestyle (HL). The primary outcome was difficulty maintaining a HL during the pandemic. Logistic regression (odds ratios and associated 95% confidence intervals (CIs)) was used to examine the associations between difficulty maintaining a HL and factors including COVID-19 hardships and mental health. RESULTS/ANTICIPATED RESULTS: Participants (N=169, 71.4% female, 41.4% essential workers) had a mean age [SD] of 49.4 [14.9] years. Over half (91/169, 54%) reported difficulty maintaining a HL. Those reporting unemployment (OR 2.3; 95% CI [1.2,4.4]; p=0.008), difficulty paying rent (OR 4.1; 95% CI [2.1,8.6]; p<0.001), or food/utilities (OR 5.5; 95% CI [2.7,11.5]; p<0.001) all had greater odds of difficulty maintaining a HL. High stress (≥5/10, scale 1-10) was associated with difficulty maintaining a HL (OR 4.1; 95% CI [2.1,8.5]; p<0.001) compared to AAs with low stress. Negative mental health (depression (OR 3.4; 95% CI [1.0,13.7]; p<0.001), anger (OR 2.5; 95% CI [0.5,18.9]; p=0.005), and nervousness (OR 4.1; 95% CI [1.1,19.5]; p=0.003) was associated with difficulty maintaining a HL compared to AAs with positive mental health. DISCUSSION/SIGNIFICANCE: Our study findings revealed that COVID-19 hardships, stress, and negative mental health impacted the ability of AAs to maintain a HL. These issues should be considered in the design and implementation of community-based health programs to promote healthy living during future public health emergencies.

OBJECTIVES/GOALS: To investigate nursing homes (NHs) acquired by private equity (PE) firms and estimate the effect of PE NH acquisitions on NH care quality for NH residents and whether PE NH acquisitions exacerbate racial inequities in quality of care. METHODS/STUDY POPULATION: My research estimates the causal effect of NH PE acquisitions on NH access and quality of care for NH residents and whether acquisitions exacerbate racial disparities in NH care for about 115 PE-owned NHs in the US, measuring the quality of care at the facility survey year level, and using an array of NH-level data sources. I identified 115 PE-owned NHs (treatment group) and 665 non-PE-owned NHs between 2003 and 2010, using the Online Survey Certification and Reporting database to obtain facility characteristics. I compare facility characteristics (e.g., payer mix, staffing levels, and quality measures such as pressure ulcers, unexpected weight loss, acuity, and health deficiencies). I will then test whether effects differ by race, with hypotheses informed by Public Health Critical Race Praxis approach. RESULTS/ANTICIPATED RESULTS: Preliminary results show that staffing levels differ between PE and non-PE-owned NHs in a way that aligns with a shift in focus toward the Medicare population i.e. short stays. We also find that deficiencies increased in PE-owned NHs compared to non-PE-owned NHs. We expect that PE acquisitions may lead to slightly widening racial disparities in NH care quality. Results may show that PE-owned NHs have a higher share of low-rated, high-BIPOC facilities. In weak markets, PE-owned NHs may have a higher share of BIPOC residents compared to highly competitive markets. This is because PE managers may prioritize cost over quality by cutting services. However, since quality measures are self-reported, except for measures related to deficiencies, this predicted lower quality of care may not be evident in observed data. DISCUSSION/SIGNIFICANCE: Understanding how PE ownership impacts nursing home care quality for long-stay residents, especially those funded by Medicaid, can help develop intervention strategies to effectively mitigate racial inequities in NH care, as Medicaid funded NH residents are more likely to be Black, Indigenous, and people of color.

OBJECTIVES/SPECIFIC AIMS: Gender affirmation is a critical aspect of the health and well-being of transgender individuals. For many transgender people, this includes changing one’s physical appearance to align with one’s felt gender. Some gender-affirming body modifications require medical interventions such as hormone therapies and surgeries. Other modifications, such as tucking to create a flat-appearing lower pelvis and binding to create a flat-appearing chest, require no external intervention. The published literature is slowly growing on the health effects of gender affirming medical interventions; however, other body modifications are understudied. As part of our needs assessment of the transgender community, we sought to understand the frequency and health impact of binding and tucking. METHODS/STUDY POPULATION: A quantitative online survey was developed based on qualitative interviews with 20 community-based key informants. The survey was available online, in English, for 6 months. Eligible participants were 18 years of age or older, lived in the Baltimore metropolitan area, and identified as transgender and/or a sex different from what was assigned on their original birth certificate. RESULTS/ANTICIPATED RESULTS: 139 participants provided complete data: 45% were assigned male at birth (AMAB) and 55% were assigned female at birth (AFAB). In total, 54% were Black, 40% White, and 9% Latinx. Of AFAB participants, 80% had bound their chest tissue. Of those who had bound, 51% bound 7 days/week, 62% bound 8+ hours per day, and 68% were concerned about the health effects of binding. The most common symptoms associated with binding were back pain (65%), shortness of breath (48.6%), bad posture (32%), chest pain (30%), and light-headedness (30%). Of AMAB participants, 71% had ever tucked, 85% of those tucked 7 days per week, 79% tucked 8+ hours per day, and 50% were concerned about the health effects of tucking. Most common symptoms included itching (28%), rash (21%), testicular pain (17%), penile pain (14%), and skin infections (12%). DISCUSSION/SIGNIFICANCE OF IMPACT: The majority of transgender participants used binding or tucking for gender-affirming body modification and at least half of them have concerns about associated health effects. Clinicians should ask transgender patients about binding and tucking behaviors and assess for common symptoms. More research is needed to better understand the benefits and risks of gender-affirming binding and tucking behaviors.

ABSTRACT IMPACT: Our implementation model translates two evidence-based nutritional and behavioral interventions to lower blood pressure, into a community-based intervention program for seniors receiving congregate meals. OBJECTIVES/GOALS: The Rockefeller University, Clinical Directors Network, and Carter Burden Network received an Administration for Community Living Nutrition Innovation grant to test whether implementation of DASH-concordant meals and health education programs together lower blood pressure among seniors aging in place. METHODS/STUDY POPULATION: n=200, >60 yr, >4 meals/week at CBN; engagement of seniors/stakeholders in planning and conduct; Advisory Committee to facilitate dissemination; menus aligned with Dietary Approaches to Stop Hypertension (DASH) and NYC Department for the Aging nutritional guidelines; interactive sessions for education in nutrition, BP management, medication adherence. Training in use of automated daily home BP monitors (Omron 20). Validated surveys at M0, M1, M3, M6. Taste preference and cost assessed through Meal Satisfaction (Likert scale) and Plate Waste measures. Primary Outcome: Change in Systolic BP (SBP) at Month 1; change in %BP controlled. Secondary: validated cognitive, behavioral, nutritional measures (SF-12, PQH-2), economics; staff/client satisfaction, trends and significant associations. RESULTS/ANTICIPATED RESULTS: n=94, x2 age =73 +/- 8 years, 65% female, 50% White, 32% Black/African American, 4% Asian, 1% American Indian, Alaskan Native, 13% Other, 32% Latino/a, 43% with income <$20,000. Mean SBP at Baseline was 137.87 +18.8 mmHg (range 98-191). Menus were adapted to provide 20% daily DASH requirements at breakfast, 50% at lunch. Participants attended classes in nutrition and medication management and were provided with and trained to use an automated home BP monitor. Meal satisfaction scores dipped briefly then met or exceed pre-DASH levels. Home BP data was downloaded every 2-4 weeks with social/behavioral support. The COVID-19 closures interfered with BP outcome data collection and meal service ceased. Primary outcome: x2 change in SBP at Month 1 = -4.41 mmHg + 18 (n=61) (p=0.713). Significant associations will be reported. DISCUSSION/SIGNIFICANCE OF FINDINGS: Our community-academic research partnership implemented the DASH diet in congregate-meal settings to address uncontrolled hypertension in seniors. COVID-19 interrupted the study, but encouraging trends were observed that may inform refinement to this community-based health intervention for seniors.

OBJECTIVES/SPECIFIC AIMS: This presentation will highlight the framework and domains of the monitoring and evaluation (M&E) System Checklist created in response to the need for practical guidelines and intended to improve the quality, efficiency, and consistency of monitoring and evaluation of the clinical and translational work. The recently published NCATS Strategic Plan (2016; p. 18) presents the following objectives and guidelines that implicitly suggest the need for sound M&E: “Objective 4-1: Continually assess and optimize internal business practices” and “Objective 4-2: Ensure all scientific programs and operational activities are conducted in a rigorous, robust and data-driven manner.” Given the complexity of clinical and translational work and associated monitoring/evaluation processes and the dearth of practical tools in the CTR evaluation area, the need for such a checklist is clear. A “checklist” (a detailed list of items/steps required, things to be done, or points to be considered) is a type of informational job aid used to improve performance, reduce failure, deal with complexity, and ensure consistency and completeness in carrying out work. Checklists are popular in many fields—due to their brevity, concreteness, order, implicit (and sometimes explicit) mandate to do things right, and expectation for a checklist’s being grounded in good practices and/or strong theory. A notable example is the famed WHO Surgical Safety Checklist (2008). The proposed M&E Checklist has been developed based on the author’s extensive experience in internal evaluation, checklist development and use, and working with the Clinical and Translational Sciences Awards (CTSAs)—as the UMN CTSI M&E Director, ACTS Evaluation SIG Chair, and a Co-Lead of the Evaluators Working Group within the NCATS CTSA Common Metrics Initiative. Although there is no “golden” algorithm that will totally suit every organization, the M&E checklist provides useful guidelines for building M&E. The Checklist presents the key concepts and important issues in M&E development and implementation. It also incorporates a synthesis of 3 grounded frameworks: King and Volkov’s Framework for Building Evaluation Capacity (2005), Simister’s Framework for Developing M&E Systems for Complex Organizations (2009), and the award-winning CDC Framework for Program Evaluation in Public Health (1999). For the purposes of the proposed Checklist, an M&E system (or framework/approach) is understood as “a series of policies, practices and processes that enable the systematic and effective collection, analysis and use of monitoring and evaluation information” (Simister, 2009; p. 1). A well-designed M&E system ensures a consistent approach to the collection, analysis, and use of information, while allowing considerable scope for different parts of an organization to develop and apply their own solutions in response to their particular situations. The M&E Checklist structured around 3 key domains (adapted from the Volkov and King ECB Checklist, 2007): (1) M&E/organizational context: taking advantage of the internal and external organizational context, administrative culture, and decision-making processes. (2) M&E structures: creating structures—mechanisms within the organization—that enable the M&E development and use. (3) M&E resources: making M&E resources available and used. For each domain, the Checklist has a number of associated categories and activities. Specifically, the checklist adopts and adapts the following useful steps from Simister’s approach: “Define the scope and purpose,” “Perform a situational analysis,” “Consult with relevant stakeholders,” “Identify the key levels and focus areas,” and “Integrate the M&E system horizontally and vertically,” as well as the CDC Framework’s steps “Engage stakeholders,” “Focus the M&E Design,” and “Ensure use and share lessons learned.”With slight modification, the organizations can also utilize the Checklist as a rubric/assessment tool to gauge the status of their M&E capacity. METHODS/STUDY POPULATION: A case study of methodological/implementation tool development. There are no human subjects in this study, thus, Study Population is not applicable to this study. This study is not subject to IRB review. RESULTS/ANTICIPATED RESULTS: The proposed checklist approach shows sound promise to not only impact individual programs and their M&E systems but to also enhance internal evaluation capacity, critical thinking, learning, strategic management, and improvement within clinical and translational science organizations. DISCUSSION/SIGNIFICANCE OF IMPACT: The ultimate goal and impact of the proposed checklist is to help ensure that organizations and their M&E teams consistently follow a few critical steps and thereby maximize the quality, efficiency, and consistency of monitoring and evaluation of the clinical and translational work. The checklist’s impact is significant in that it fills the current gap in the practice, literature, and methodology and provides practical guidance for CTR (and other) organizations and programs striving to improve the quantity and quality of evaluation.

BACKGROUND: Of the ~50 million cases of epilepsy worldwide, an estimated 80% originate from cortical areas implicated in language. Although the precise language loci can vary significantly across individuals, electrical stimulation mapping for eloquent areas has become standard of care in resective surgery for frontotemporal epilepsies. Although considerable work has been done to establish the minimum necessary resection distance from these sites to preserve language, no previous work has shown how these representations are affected by proximal resections. METHODS: Between 1967 and 2005, 22 patients [seizure onset (y): 11.5 (0.2–33); age at initial resection (y): 27.7 (10–39); time between operations (y): 8.4 (1–20.3); sex: 14 females; hemisphere: 21 left] underwent repeated perisylvian resective epilepsy surgeries of the language-dominant hemisphere. Each set of operations comprised intraoperative language mapping and cortical photographs. Using this data, a Bayesian hierarchical model was used to estimate the variability of language localization pre-resection Versus post-resection. RESULTS: The statistical model shows the posterior median difference in cortical location of language sites preresection Versus postresection is 0.6 cm, with a posterior 95% CI of 0.4 cm, 0.9 cm. CONCLUSION: This work suggests permanence in cortical language centers following resection of infringing cortex, while providing a reasonable statistical method to impute unobserved sites during the mappings, and confirming the validity of using proximity sites defined by shortest distance in the current literature.

OBJECTIVES/GOALS: 1. Describe method of Community Based System Dynamics. 2. Describe CBSD as used in addressing structural racism in a previously redlined community. 3. Review example causal loop diagrams and simulation models developed using CBSD focused on structural racism as a social determinant of health. METHODS/STUDY POPULATION: Community Based System Dynamics (group model building and computer simulation development). Cuyahoga County, Ohio, a previously redlined community of more than 1.2 million people. RESULTS/ANTICIPATED RESULTS:Actionable Community identified leverage points for action to mitigate structural racism. Computer simulation models built on causal loop diagrams built by Community members with loved experience. DISCUSSION/SIGNIFICANCE: Structural and social determinants of health, such as racism, have profound impacts on the health of individuals and populations, however they remain challenging to address in pragmatic ways. CBSD is a novel method to engage community members not proximal to the impact of structural racism in generating maps of the complex, dynamic system they live in.

Precision Medicine/Health

OBJECTIVES/GOALS: While strategies for community engagement in health research and clinical trials are well documented, participation from underserved populations remains low. Our research team conducted a series of Community Engagement Studios for community members to discuss what is still needed for them to engage in health research. METHODS/STUDY POPULATION: In the spring of 2023, our research team conducted four community engagement studios using the Vanderbilt Community Engagement (CE) Studio model. Community members were recruited through health councils- which are a community-led collaborative, focused on health at the county level throughout the state. In the CE Studio model community members or stakeholders are referred to as experts. In total, 31 experts from 12 different health councils from around the state participated in the CE Studios via Zoom. The CE Studios centered around two main questions 1.) What do communities want to know before agreeing to participate in research? And 2.) When a study is presented as an opportunity for your community, what things need to be addressed to see if it is a good fit? RESULTS/ANTICIPATED RESULTS: Themed summaries for each CE Studio and one overall themed summary were developed by a designated notetaker on the research team. Of novelty were cultural considerations for each region that included recommendations such as “Foster kinship between those doing the research and the community” speaking to the shared community bond that unites people and the need for researchers to also spend time creating meaningful community bonds throughout the research process. The CE Studio overall summary revealed two main themes for researchers: 1.) Things that help with research participation, and 2.) Things that get in the way of research participation. Overall themes echoed documented best practices for community engagement efforts. DISCUSSION/SIGNIFICANCE: Each CE studio revealed cultural considerations that included recommendations to researchers. Overall themes echoed documented best practices for community engagement efforts implying that while strategies for researchers to engage with communities are well known, more needs to be done to continue to implement these practices.

OBJECTIVES/GOALS: Despite its critical importance in reproductive health, access to abortion care continues to be impeded by laws grounded in religious, political, or other ideologies. We will characterize abortion attitudes among US men who live in areas with restrictive abortion laws using qualitative methods. METHODS/STUDY POPULATION: We will use a semi-structured interview guide to elicit men’s attitudes about abortion, characterized within moral, legal, religious, political, and other domains. Inclusion criteria include English-speaking cisgender men, ages 18 to 65 who live in states with the most restrictive abortion laws as defined by the Guttmacher Institute. We will recruit participants through Facebook ads and interviews will continue until theoretic sufficiency. Using an inductive thematic analysis approach, transcripts will be coded for emergent themes by two researchers independently in QRS NVivo 12.0, with concurrent refinement of themes as interviews are completed. RESULTS/ANTICIPATED RESULTS: We will elucidate emergent themes regarding men’s abortion attitudes which could include how men think of abortion as a medical, moral, or personal reality, why they do or do not support abortion provision, among many other possibilities. We anticipate that researchers can use the data obtained from this study to begin to build a conceptual framework of abortion attitudes among US men who lives in restrictive states. DISCUSSION/SIGNIFICANCE OF IMPACT: This study will fill an important gap in the literature by qualitatively characterizing abortion attitudes among a population that has political influence on abortion access. Results can inform policy and advocacy campaigns aimed at shifting public abortion attitudes towards increased acceptance.

ABSTRACT IMPACT: This translational study demonstrates a method for identifying possible mechanisms underlying a highly effective randomized control trial intervention so that a university-public health agency partnership might replicate intervention components in a scalable, feasible, community version of the program. OBJECTIVES/GOALS: The Barbershop Study was a cluster randomized control trial which demonstrated that clinical pharmacist directed care, provided to African American men in community barbershops, significantly improve hypertension control. We sought to understand which components of the intervention the participants and implementers considered most important. METHODS/STUDY POPULATION: Enrollment in the Barbershop Study included 319 men from 52 barbershops across Los Angeles. Two specialty trained clinical pharmacists led the intervention. We performed 32 structured interviews of 20 study participants, 10 barbers, and 2 clinical pharmacists approximately 1 year after the study’s completion. Interviews consisted of 27, 24 and 19 questions for barbers, participants, and pharmacists, respectively. Interviewees were asked about their experience in the study, barriers and facilitators to participation, effective aspects of the intervention, and less helpful components of the design. Interviews were recorded performed by a research assistant uninvolved in the study. Recordings were then transcribed for a qualitative thematic analysis. RESULTS/ANTICIPATED RESULTS: We anticipate facilitators of participant engagement to include the provision of care in the community and integration of services into a regular task (getting their hair cut). Based on prior conceptual models, we also anticipate the provision of care in a trusted setting to be an effective means to enhance participants’ willingness to follow clinical instructions. An anticipated barrier for participants includes the need to go to an offsite pharmacy to pick up their medications. For barbers, we anticipate themes including a desire to help their community, while barriers include potential decreased productivity due to time spent counseling participants. Pharmacists are expected to identify an enhanced sense of importance in their work, while identifying the need to travel as a barrier to the intervention. DISCUSSION/SIGNIFICANCE OF FINDINGS: Insights from this qualitative analysis may assist with adaptation of the highly effective Barbershop intervention, allowing it to be rolled out at scale. If done successfully, achieved reductions in blood pressure may result in reduced health disparities and prevent thousands of strokes, heart attacks and deaths.

OBJECTIVES/SPECIFIC AIMS: To validate previously published psychometric scales capturing interpersonal or healthcare-related trust in a target population of women with a history of substance use disorder seeking substance abuse treatment in a community-based setting. METHODS/STUDY POPULATION: Participants are enrolled at The Next Door, Inc. (TND) and Renewal House (RH), 2 community agencies in metropolitan Nashville that provide substance abuse treatment and post-incarceration re-entry services for women with a history of substance use disorder. We will enroll 300 participants to provide sufficient power for statistical psychometric validation. Inclusion criteria include adult women with self-identified history of substance use disorder seeking substance abuse treatment within seven days of initiation of inpatient residential or intensive outpatient treatment at TND or RH. Participants complete a one-time online survey comprising a demographics questionnaire, Rotter Interpersonal Trust Scale, Wake Forest Trust in Physician Scale, Revised Health Care System Distrust Scale, 5-item RAND Social Desirability Scale, and Adverse Childhood Events Survey. Participants then individually participate in a modified protocol of the “Trust Game.” Predictor variables for multivariate analysis collected include age, race/ethnicity, gender identification, number of days in current treatment, number of prior substance abuse treatment programs, and number of adverse childhood events. RESULTS/ANTICIPATED RESULTS: Each individual scale will be assessed for item analysis, factor analysis, construct validity, content validity, and reliability and compared with general population sample values published in the literature. We will use multivariate analysis to determine the impact of potential predictor variables on specific types of interpersonal or healthcare-related trust. We anticipate having preliminary results to present in April. DISCUSSION/SIGNIFICANCE OF IMPACT: Women who seek substance abuse treatment in the community face unique challenges compared to their male counterparts, including higher rates of prior interpersonal trauma, co-occurring psychiatric diagnoses, and more serious physical health problems. Characteristics such as these highlight the need for regular healthcare engagement in the setting of an increased risk of decreased interpersonal or healthcare-related trust. Prior qualitative research demonstrates that trust building is seen as an essential component of care in ongoing substance abuse treatment for women in this population. Validation of psychometric healthcare-related trust scales in a population of women seeking substance abuse treatment in a community based setting will provide a framework for future quantitative inquiry into the impact of healthcare-related trust on health outcomes, healthcare engagement, and treatment retention for this target population. Similarly, it will also facilitate inquiry into the effectiveness of specific treatment programs or interventions on improving therapeutic trust building.

OBJECTIVES/GOALS: Our hypothesis is that microneedle array (MA) extraction of interstitial fluid (ISF) will enable minimally invasive quantitation of heavy metal (HM) exposure. We aim to establish analytical parameters for ICP-MS analysis of HMs, quantify baseline HM content in ISF vs other fluids, and characterize a mixed HM exposure model. METHODS/STUDY POPULATION: Ten healthy human volunteers were recruited into the study, approved by the UNM Human Research and Resource Committee Each subject had blood and urine collected. ISF was also collected using 3D-printed MAs inserted into the forearm. Additionally, twelve Sprague Dawley rats were unexposed (n=6) or exposed (n=6) to ad libitum water containing a mixture of uranium (U), cadmium (Cd), vanadium (V), and arsenic (As), each at 5X the maximum contaminant level (MCL) for drinking water under a protocol approved by the UNM animal care and use program. Human and animal fluids were analyzed, using ICP-MS, to quantify the levels of U, Cd, V, and As. RESULTS/ANTICIPATED RESULTS: Recent advances in ISF extraction and analysis suggest a minimally invasive method that can be adapted to monitor HM exposure and biological loads longitudinally in both localized and dispersed communities. ISF can be collected with MAs and is a rich source of disease and exposure biomarkers. However, determining biological loads remains challenging due to the need to collect blood or urine from a dispersed rural population over time. Our preliminary results suggest similar HM concentrations in ISF, compared with blood in small unexposed human and animal populations. All four metals can be successfully quantified in tandem using ICP-MS. DISCUSSION/SIGNIFICANCE: Chronic exposure to heavy metals (HM) is associated with detrimental health effects. Exposure to multiple HMs is suspected to have additive or synergistic harmful effects. We envision a wearable microneedle patch that could be mailed to individuals or distributed through community centers, worn for a few hours, and returned to a central laboratory.

As the USA and the rest of the world raced to fight the COVID-19 pandemic, years of investments from the National Center for Advancing Translational Sciences allowed for informatics services and resources at CTSA hubs to play a significant role in addressing the crisis. CTSA hubs partnered with local and regional partners to collect data on the pandemic, provide access to relevant patient data, and produce data dashboards to support decision-making. Coordinated efforts, like the National COVID Cohort Collaborative (N3C), helped to aggregate and harmonize clinical data nationwide. Even with significant informatics investments, some CTSA hubs felt unprepared in their ability to respond to the fast-moving public health crisis. Many hubs were forced to quickly evolve to meet local needs. Informatics teams expanded critical support at their institutions which included an engagement platform for clinical research, COVID-19 awareness and education activities in the community, and COVID-19 data dashboards. Continued investments in informatics resources will aid in ensuring that tools, resources, practices, and policies are aligned to meet local and national public health needs.

OBJECTIVES/SPECIFIC AIMS: The incidence of papillary thyroid cancer (PTC) has sharply increased in recent decades. Though thyroid resection is the best treatment modality, there is significant variation in practice involving use of prophylactic central lymph node dissection (PCLND) at time of thyroidectomy. Recently, a threshold number for lymph node (LN) yield was determined to assure adequacy of lymphadenectomy in evaluating occult nodal disease via PCLND for pathologic T3, clinical N0, M0 PTC patients, for whom guidelines recommend PCLND. This study assesses the prevalence of adequate prophylactic LN dissection (APLND) and determines its association with patient, and disease characteristics. METHODS/STUDY POPULATION: Adult patients receiving surgery for pT3 cN0 M0 PTC >1 cm were identified from the National Cancer Data Base, 2004–2015. APLND for pT3 stage was defined as removing 8 or more LNs, based on recent literature. Univariate and multivariate logistic regression models were employed to determine factors associated with APLND and inadequate prophylactic LN dissection (IPLND). RESULTS/ANTICIPATED RESULTS: In total, 18,755 patients were included: 2905 (10.1%) had APLND; 15,849 (89.9%) had IPLND. Rate of APLND increased from 4.9% to 17.9% over the decade. Patients receiving APLND were younger than those receiving IPLND (47 vs. 52 years, respectively, p<0.001). The proportion of cases found to be LN positive in the APLND group was 64.5%, while that in the IPLND group was 18.2% (p<0.001). After adjustment, Whites were more likely than Blacks to receive APLND [OR 1.86 (95% CI 1.51–2.30), p<0.001]. The adjusted OR of receiving APLND was higher at academic centers [1.76 (1.29–2.41), p<0.001] and at integrated centers [1.77 (1.25–2.51), p<0.001], compared with community facilities. After adjustment, patients with multifocal tumors were more likely to receive APLND than those with unifocal tumors [1.28 (1.17–1.41), p<0.001]. Unplanned 30-day readmission rate was higher in the APLND group (2.4%) compared to the IPLND group (1.7%, p<0.001); this remained significant after adjustment [OR for APLND 1.80 (1.31–2.47), p<0.001]. There was no significant difference in the likelihood of receiving radioactive iodine between patients who underwent APLND Versus IPLND [1.00 (0.90–1.00), p=0.6]. DISCUSSION/SIGNIFICANCE OF IMPACT: APLND is associated with a higher likelihood of finding metastatic LNs, and an increased risk of unplanned short-term readmissions. The rate of APLND has increased over time, but still only a minority of thyroid cancer patients undergo adequate prophylactic surgery. Disparities exist based on patient, facility, and disease characteristics. Further work is needed to study the association between adequacy of dissection and disease recurrence.
