OBJECTIVES/SPECIFIC AIMS: The study aims to determine the current clinical research training interventions of MD-PhD programs and how effective they are in promoting clinical research self-efficacy. METHODS/STUDY POPULATION: A national survey of MD-PhD trainees was conducted in 2018 to identify clinical research training methods and self-efficacy for clinical research skills. MD-PhD program directors and coordinators from 108 institutions were asked to distribute the survey to their students. Responses were received from 61 institutions (56.5%). Responses were obtained from 647 MD-PhD students in all years of training, representing 17.9% of the 3613 possible participants at the 61 medical schools represented. No compensation was provided for this study. RESULTS/ANTICIPATED RESULTS: The primary methods of clinical research training reported by students included didactics, mentored clinical research, didactics plus mentored clinical research, didactics plus clinical research practicum, and didactics plus mentored clinical research plus clinical research practicum. A quarter of all participants reported having no clinical research training. Clinical research self-efficacy was then correlated with the amount of clinical research training. Students exposed to no clinical research had the lowest self-efficacy in clinical research skills and students experiencing didactics plus mentored clinical research plus clinical research practicum had the highest perceived self-efficacy in clinical research domains. DISCUSSION/SIGNIFICANCE OF IMPACT: This is one of the first studies assessing clinical research training methods for MD-PhD students and assessing their efficacy. We found that of all students questioned, 25% mentioned had not received any type of clinical research training. The remaining students identified 5 research training methods that institutions currently use. This work highlights the importance of clinical research experience students need to improve their self-efficacy, a major influence on research career outcomes.

OBJECTIVES/GOALS: To examine pharmacy students’ and patients’ perspectives on use of an automatic pill dispenser (APD) and adherence device, and secondly, to identify patient characteristics impacting selection of an APD. This knowledge will assist pharmacists in making appropriate device recommendations that improve medication adherence and effectiveness. METHODS/STUDY POPULATION: One hundred fifty-three pharmacy students participated in a personal APD simulation, living the life as a person taking medication. Students then each identified an actual patient exhibiting medication nonadherence from pharmacy records at their work setting, provided them with an APD free of charge and instructed them on its use. The students later interviewed their patients and reported on their patients’ ability to use the APD, as well as their perspectives (likes and dislikes) on the features of the device. Students identified individual patient characteristics associated with successful use of the APD. This new knowledge will aid these future pharmacists in making recommendations for medication adherence devices for their patients. RESULTS/ANTICIPATED RESULTS: In general, patients perceived more difficulty with use of the 10 APD features than did students. Over half of the patients indicated that the following features were a distinct advantage in adherence: individual medication compartment size, method of loading medications, alarm, flashing light, ability to lock the dispenser, and method of retrieving the medication from the device. Patients felt that the biggest disadvantage was its bulky size and lack of portability. In spite of individual difficulties with use, the research findings showed that persons who are elderly, homebound, have memory problems, take multiple medications and/or have complex regimens are most likely to benefit from the device features and exhibit improved adherence to their prescribed medication regimen. DISCUSSION/SIGNIFICANCE: Medication adherence rates in the U.S are agreed upon to be about 50% - highly relevant to healthcare practitioners since several studies suggest a correlation between adherence and improved health outcomes. Pharmacists must be knowledgeable about non-adherence tools and consider patient characteristics when recommending an adherence aid.

OBJECTIVES/GOALS: To establish the root causes of vaccine hesitancy in populations who have less equitable access to health and healthcare services, and experience healthcare inequities, related to the environmental and social determinants of health, through community engagement and conversations, collaboration, circulation, and communication. METHODS/STUDY POPULATION: Existing data from a cross-sectional survey, vaccine hesitancy (VH) parent study, entitled 'Western New York (WNY) COVID-19 Collaborative to Promote Vaccine Acceptance,' conducted July to November 2022, after IRB approval, will be qualitatively analyzed. In the parent study, surveys were administered in WNY community congregations and community centers to individuals that historically have less equitable access to healthcare resources and may encounter health and healthcare disparities. Minorities, in urban and rural areas, age eighteen and older were identified through the NYS Department of Health’s Immunization Information System for daily vaccination rates. A qualitative analysis, promoting fact base HL, and building an inferential statical machine learning tool are the next steps. RESULTS/ANTICIPATED RESULTS: We anticipate the results to show an interplay of multiple factors, including personal, cultural, historical, social, and political, and varies depending on circumstances of time, place, and the type of vaccine being offered. Additionally, a lack of awareness or understanding of vulnerabilities and seriousness of vaccine-preventable diseases, lack of trust in health care providers, social norms, distrust of the healthcare system, biomedical research, and government policy, limited knowledge and understanding of vaccine safety and efficacy, and fear/uncomfortable with needles, as well as the less addressed environmental and social determinants of health associated with racial/ethnic minorities in communities with limited resources may also contribute to VH and less favorable health outcomes. DISCUSSION/SIGNIFICANCE: Identifying people who historically have less equitable access to healthcare resources and may be more likely to resist healthcare services, due to distrust in the system is important. Creating and evaluating an innovative tool to predict refusal of public health interventions is essential to avoid spreading preventable diseases.

OBJECTIVES/GOALS: The purpose of this study was to develop behavioral economic purchase tasks to assess interest in CM as a function of treatment cost and perceived effectiveness of CM as a function of abstinence incentive size in alcohol drinkers. Additionally, these purchase tasks are being assessed for their clinical utility in an ongoing clinical trial. METHODS/STUDY POPULATION: Alcohol drinkers recruited from Amazon Mechanical Turk completed behavioral economic purchase tasks measuring demand for CM based on targeted abstinence intervals and treatment effectiveness and alcohol use disorder severity assessments. Nonlinear mixed effects modeling was used to fit demand curves and assess the relationship between individual characteristics and demand metrics for CM. Ongoing analyses involve administering the same behavioral economic purchase tasks in heavy alcohol users in the ongoing clinical trial, which is aimed at reducing alcohol use through remotely implemented CM. RESULTS/ANTICIPATED RESULTS: Mechanical Turk participants reported higher probability of abstinence when offered larger incentives and required larger incentives when duration of abstinence required to earn the incentive was increased. Additionally, willingness to pay for treatment increased as effectiveness of treatment increased. It is anticipated that these patterns will be observed in the clinical trial participants. DISCUSSION/SIGNIFICANCE: Abstinence interval and treatment effectiveness are important features to consider when developing effective CM for widespread use, as these variables affected participants likelihood of being abstinent and their interest in treatment. We are currently working on verifying the results of these assessments in clinical trial participants.

OBJECTIVES/GOALS: A new researcher-facing module to support community engaged research has been added to the updated COALESCE website and user traffic was tracked since last reporting. We describe the process of development and the features of the new module, past 2-year traffic, and plans to develop a community facing module. METHODS/STUDY POPULATION: We monitored the number of unique users of COALESCE (teamscience.net) between 2017 and 2019 to determine if traffic slowed, stayed the same, or increased since teamscience.net was physically updated to function on mobile devices. In December 2019, a new module was launched to introduce researchers to the stages of team science community engaged research. To develop the module, we collaborated with academic partners at University of Illinois-Chicago to identify 3 local historic research case studies in and to characterize how each exemplified a team science stage: assembly, launch, or maturation. After interviewing key team members from each study, we iterated storyboards and scripts in collaboration with community engaged research experts and case study team members. The module was built, tested, and launched. RESULTS/ANTICIPATED RESULTS: In the 6 years between 2011 through 2017, the site attracted 16,016 unique visitors (approximately 2699 per year). In 2 years from 2017 through 2019, since the modernization of the website, user traffic has held steady or grown, attracting 6992 unique visitors (approximately 3496 per year). Our newly posted researcher-facing module highlights team assembly in the case a task force charged with reducing disparity in breast cancer outcomes in Chicago, team launch in a study to improve asthma management in a local FQHC, and team maturation in a study comparing clinic-based to public school-based treatment of disruptive behavior. We will soon create a companion community-facing module and resources to address identified needs for community partners engaging in research with academic institutions. DISCUSSION/SIGNIFICANCE OF IMPACT: COALESCE (teamscience.net) remains the first and only open-access, online training in team science for health professionals. Recent updates have improved usability and expanded available resources. We launched a comprehensive module for academics interested in community engaged research; future work will develop parallel community facing resources.

OBJECTIVES/SPECIFIC AIMS: The purpose of this study is to use the baboon as a novel animal model for breath research and to identify and characterize baboon breath metabolites that reflect cardiometabolic function to inform us in the development of a noninvasive, cost-effective, and repeatable point-of-care diagnostic breath test. METHODS/STUDY POPULATION: Blood and urine was collected from control and IUGR at the approximate age of 3.5 years. Both groups were then placed on a high fat, high sugar, high salt diet for 7 weeks, after which blood, urine, and breath were collected. The breath samples were then subjected to comprehensive, 2-dimensional gas chromatography coupled with time-of-flight mass spectrometry. Using ChromaTOF software, breath VOCs were identified with at least an 80% spectral match against the National Institute of Standards and Technology (NIST) chemical reference library. The raw data were then statistically analyzed using MetaboAnalyst. We then interrogated multiple online databases to characterize and identify the role of VOCs that were present in both control and IUGR groups. RESULTS/ANTICIPATED RESULTS: Preliminary analyses of the breath VOCs indicate differences in expression between sexes and in control Versus IUGR groups. These results indicate unique “breath signatures.” Further analysis of the breath VOCs reveals the presence of metabolites that are involved in β-oxidation and oxidative stress pathways. DISCUSSION/SIGNIFICANCE OF IMPACT: This breath study, a first of its kind, will develop the baboon as a superior animal model for breath biomarker research. Our observed unique “breath signatures” indicate changes in lipid metabolism and oxidative stress pathways, which we hypothesize are the early metabolic changes at the cellular level that are not yet reflected in clinical lab measures. Future directions include analyzing breath VOCs that did not meet 80% spectral match, validation using SPME technology and commercial standards, and initiating a human pilot study in clinically obese, at-risk children in collaboration with physicians at the Children’s Hospital of San Antonio to develop a noninvasive, cost-effective, rapid, and repeatable point-of-care diagnostic breath test.

OBJECTIVES/GOALS: Translating the science of vaccines to health and public health practice requires understanding how vaccine risks and benefits are understood and applying that knowledge to community translation. During the pandemic the lack of this knowledge became apparent. METHODS/STUDY POPULATION: Through the PACER community engagement special interest group of the ACTS, the University of Florida(UF)/Florida State University and 5 other CTSIs community engagement programs received Center for Disease Control and Prevention funding for the Program to Alleviate National Disparities in Ethnic and Minority Immunizations in the Community (PANDEMIC) to translate vaccinations into the community. At UF, HealthStreet’s Community Health Workers, CTSI Mobile Health Vehicle nurses, and Institute of Food and Agricultural Sciences extension agents collaborated to engage adults throughout the North and Central part of the state on their vaccine status and perceptions and to offer them vaccines. RESULTS/ANTICIPATED RESULTS: Through UF, 4,587 people have been interviewed in community settings using the Survey of Perceptions; 25% (1,125) had not received any COVID-19 vaccine. Among differences in perceptions, those vaccinated versus unvaccinated perceived people to be getting vaccines because they cut down on disease spread (28.9% vs. 15.2%), and perceived people NOT to be getting vaccinated because of misinformation/ignorance (27.1% vs. 11.0%) and political beliefs (16.3% vs. 6.7%). Both vaccinated and not perceived lack of trust as a reason to not get vaccinated (41.3% vs 46.4%). When asked what people were doing instead of vaccination, those vaccinated versus unvaccinated responded that people were doing nothing/very little much more often (40.6% vs. 21.8%) but were less likely to say ’trying to stay healthy’ (9.1% vs. 18.9%). DISCUSSION/SIGNIFICANCE: The science of translating from bench through clinical trials and to common health and public health practice requires knowledge of reasons for successful adoption. This survey adds to knowledge of perceptions towards vaccines that inhibit translation and biases toward the vaccine-hesitant.

OBJECTIVES/GOALS: The discipline of plastic and reconstructive surgery (PRS) is poorly understood by the public, primary care physicians, and nurses. The aim of our study is to assess medical students’ knowledge and perceptions of PRS as a discipline and explore factors influencing these opinions. METHODS/STUDY POPULATION: To assess medical student’s knowledge and perception of PRS, we distributed an online survey to all medical students at all training levels (i.e. first year to fourth year) enrolled at UCSF School of Medicine, San Francisco, CA during 2019-2020 academic year. In the survey, participants were asked to match 12 surgical subspecialties with 36 operative procedure scenarios. In addition, the survey included questions investigating the most common social medical platform used by medical students and the role of medical social media accounts in contributing to their knowledge of surgical subspecialties. RESULTS/ANTICIPATED RESULTS: Medical students demonstrated a profound gap in knowledge in plastic surgery. The majority of respondents correctly identified plastic surgeons as the primary surgeons performing the cosmetic procedures listed (abdominoplasty, facelift, and liposuction). PRS was identified as the primary specialty involved in breast reconstruction (94.4%) and burns surgery (88.9%). There was poor understanding of the role of plastic surgeons in hand surgery(16.6%), craniofacial surgery(14.8%), and head and neck cancer surgery(9.3%). 52.4% of respondents follow medical social media accounts and 45.6% of respondents indicated that social media contributed to their knowledge of surgical subspecialties. DISCUSSION/SIGNIFICANCE OF IMPACT: Medical students, who form the next generation of doctors, have limited knowledge regarding versatile applications of PRS. Misconceptions about the discipline of PRS negatively impacts resource allocation and hinders the delivery of care to patients that would profoundly benefit from this specialty. CONFLICT OF INTEREST DESCRIPTION: No authors have financial disclosures or conflicts of interest to declare.

OBJECTIVES/SPECIFIC AIMS: Deep brain stimulation is currently being evaluated as an experimental therapy for various psychiatric disorders, as well as being investigated as a method for mapping emotional brain functions. This growing area of research requires sensitive measures to quantify effects of stimulation on emotional processing. The current study examined the effects of acute stimulation to 2 limbic regions—the subcallosal cingulate (SCC) and the amygdala—on bias in the perception and evaluation of emotional facial expressions. We hypothesized that transient electrical stimulation to the limbic system would produce acute reductions in negative bias, consistent with its antidepressant effects in patients with severe depression. METHODS/STUDY POPULATION: The current study uses a novel affective bias task, developed to rapidly and covertly quantify emotional state. Over 4–6 minutes, patients rate the intensity and valence of static images of emotional facial expressions. We examined effects of electrical brain stimulation in 2 groups: patients with treatment-refractory depression undergoing SCC DBS therapy, and epilepsy patients undergoing amygdala stimulation via stereo-EEG electrodes during inpatient intracranial monitoring. DBS patients completed the task under stimulation and sham conditions during monthly visits over the first 6 months of therapy, as well as daily during a 1 week, blinded period of DBS discontinuation at the 6-month time point. Epilepsy patients completed the task under stimulation and sham conditions at a single visit. Mixed linear models and paired-samples t-test were used to investigate effects of stimulation as well as depression scale scores on affective bias ratings. RESULTS/ANTICIPATED RESULTS: Four SCC DBS patients showed significant effects of stimulation (p<0.0001) and depressive state (p<0.0001) on affective bias scores across 6 months of chronic DBS therapy, where emotional faces were perceived as less sad with stimulation ON, as well as during visits in which patients were nondepressed (typically later in the treatment course). Furthermore, 2 DBS patients showed rapid negative shifts in bias following acute blinded discontinuation of chronic stimulation, an effect which persisted over the 1-week period of discontinuation (t29=−2.58, p=0.015), in the absence of any self-reported change in mood. Likewise, 6 epilepsy patients showed significant positive shifts in affective bias with acute amygdala stimulation (t5=−4.75, p=0.005). Current analyses are investigating electrophysiological, autonomic and facial motor correlates to affective bias in these patients. DISCUSSION/SIGNIFICANCE OF IMPACT: Affective bias has revealed rapid, significant changes with stimulation at 2 limbic targets—one a white matter hub and one a nuclear subcortical structure—suggesting the task’s utility as an emotional outcome measure in brain stimulation studies. These stimulation-sensitive measures may provide a new metric to track treatment response to deep brain stimulation therapy for affective disorders. Future studies will determine whether affective bias can predict neuropsychiatric complications in patients undergoing stimulation mapping of brain circuitry ahead of resection surgery for epilepsy.

OBJECTIVES/SPECIFIC AIMS: Clostridium difficile infection (CDI) is the most common cause of antibiotic-associated diarrhea and an increasingly common infection in children in both hospital and community settings. Between 20% and 30% of pediatric patients will have a recurrence of symptoms in the days to weeks following an initial infection. Multiple recurrences have been successfully treated with fecal microbiota transplantation (FMT), though the body of evidence in pediatric patients is limited primarily to case reports and case series. The goal of our study was to better understand practices, success, and safety of FMT in children as well as identify risk factors associated with a failed FMT in our pediatric patients. METHODS/STUDY POPULATION: This multicenter retrospective analysis included 373 patients who underwent FMT for CDI between January 1, 2006 and January 1, 2017 from 18 pediatric centers. Demographics, baseline characteristics, FMT practices, C. difficile outcomes, and post-FMT complications were collected through chart abstraction. Successful FMT was defined as no recurrence of CDI within 60 days after FMT. Of the 373 patients in the cohort, 342 had known outcome data at two months post-FMT and were included in the primary analysis evaluating risk factors for recurrence post-FMT. An additional six patients who underwent FMT for refractory CDI were excluded from the primary analysis. Unadjusted analysis was performed using Wilcoxon rank-sum test, Pearson χ2 test, or Fisher exact test where appropriate. Stepwise logistic regression was utilized to determine independent predictors of success. RESULTS/ANTICIPATED RESULTS: The median age of included patients was 10 years (IQR; 3.0, 15.0) and 50% of patients were female. The majority of the cohort was White (89.0%). Comorbidities included 120 patients with inflammatory bowel disease (IBD) and 14 patients who had undergone a solid organ or stem cell transplantation. Of the 336 patients with known outcomes at two months, 272 (81%) had a successful outcome. In the 64 (19%) patients that did have a recurrence, 35 underwent repeat FMT which was successful in 20 of the 35 (57%). The overall success rate of FMT in preventing further episodes of CDI in the cohort with known outcome data was 87%. Unadjusted predictors of a primary FMT response are summarized. Based on stepwise logistic regression modeling, the use of fresh stool, FMT delivery via colonoscopy, the lack of a feeding tube, and a lower number of CDI episodes before undergoing FMT were independently associated with a successful outcome. There were 20 adverse events in the cohort assessed to be related to FMT, 6 of which were felt to be severe. There were no deaths assessed to be related to FMT in the cohort. DISCUSSION/SIGNIFICANCE OF IMPACT: The overall success of FMT in pediatric patients with recurrent or severe CDI is 81% after a single FMT. Children without a feeding tube, who receive an early FMT, FMT with fresh stool, or FMT via colonoscopy are less likely to have a recurrence of CDI in the 2 months following FMT. This is the first large study of FMT for CDI in a pediatric cohort. These findings, if confirmed by additional prospective studies, will support alterations in the practice of FMT in children.

OBJECTIVES/GOALS: Clinical and epidemiological studies focusing on Hispanics/Latinos are often designed by academic researchers with little input from mental health professionals in underserved communities. Our objective is to establish an academic-community partnership in South Texas to help improve mental health outcomes of Hispanics. METHODS/STUDY POPULATION: Hispanics in the Rio Grande Valley (RGV, South Texas) are burdened with high rates of diabetes and obesity, and interventions have been identified for these conditions, but there is less information about strategies that may help improve their mental health status and address needs. We have explored mental health and psychological factors in Hispanics/Latinos in Latin America (Gil etal., 2021) and consider community participation in the research process to be an understudied topic. Thus, in the present study, we recruited mental health professionals in the RGV to establish an academic-community partnership as a strategy to facilitate translational research that focuses on RGV Hispanics. Partners worked as a team to generate information, identify problems and solutions, and design future projects. RESULTS/ANTICIPATED RESULTS: Our academic team (at the University of Texas Rio Grande Valley) successfully established a partnership with the Cameron County Mental Task Force (CCMHTF), a non-profit organization in South Texas that seeks to “meet the mental and behavioral health needs of the people” in South Texas. The CCMHTF comprises 12 board members that are representative of RGV mental health providers: counselors, social workers, academic clinicians, hospital and county employees, and mental and behavioral health facility providers/clinicians. Our partnership generated qualitative descriptions of the mental health needs of RGV Hispanics/Latinos and barriers to access and utilization of mental health services in South Texas. In the future (phase 2 of the study), we plan to report results of focus groups and mental health assessments. DISCUSSION/SIGNIFICANCE: Hispanics/Latinos are underrepresented in clinical/translational research, and this lack of representation is particularly true for Hispanics/Latinos living along the U.S.-Mexico border of the RGV, South Texas. Our academic-community partnership may serve as a model to facilitate translational research in underserved Hispanic communities.

ABSTRACT IMPACT: This real-world study of what students value in crisis leadership fills an important gap in the literature and may inform future leadership development programs in undergraduate medical education. OBJECTIVES/GOALS: Leadership training is of growing importance and prevalence in medical education. The COVID-19 pandemic provides a unique insight into the qualities students value in leaders. Our qualitative study examined these leadership themes and provides a grounding for future development of leadership programs. METHODS/STUDY POPULATION: A conventional qualitative approach was used in order to allow open expression of ideas related to leadership in a pandemic. The authors developed a 5 free-text question survey instrument aimed to uncover student perceptions of leadership both during the current pandemic and in crises in general. A participant pilot was performed in order to ensure readability and ease of understanding. We used thematic analysis to examine the content of the survey responses, and inductive coding of the responses allowed identification of emerging themes. Medical students at the University of Michigan were surveyed. RESULTS/ANTICIPATED RESULTS: In total, 162 students completed the survey. The demographic characteristics of participants are shown in Table 1. Median age was 25 years old (range, 22-39). There was good representation from the 4 classes in the medical school with 20-30% from each medical school class and 5% of dual degree students. Thematic analysis demonstrated that students value personal characteristics of excellence in their leaders with an orientation towards helping other people. Students believe that leaders must know how to interpret and use information and then that these leaders must be able to communicate expertly to guide organizations. The final theme that emerged is that effective leaders must commit to decisive action. DISCUSSION/SIGNIFICANCE OF FINDINGS: This study took place at a time of unprecedented crises and response examples were grounded in this real-world practice of leadership. These results and themes that emerged fill a critical gap and may facilitate future curriculum development for medical students and trainees.

ABSTRACT IMPACT: This work demonstrates the integration of interactive mindfulness and dialogue sessions in curricula is both desired by students and effective in conferring resilience, a protective factor that may aid in maintaining wellbeing of trainees interested in pursuing graduate studies in biomedical research and science. OBJECTIVES/GOALS: To support student futures in the field of biomedicine, Mayo Clinic Graduate School of Biological Sciences utilized digital platforms to deliver a summer research program in the summer of 2020. One goal of this program, in addition to scholastic outcomes and research experience, was to support and improve the wellbeing of college student participants. METHODS/STUDY POPULATION: Following the cancellation of in-person summer research programs, students were invited to attend a digital Summer Foundations in Research program. The 4-week program included 4 small group dialogue sessions led by trained facilitators and 4 large group mindfulness seminars followed with 3 Q/A style small group sessions. Surveys were delivered on days 1, 27, and 3 months following the program. Wellbeing measures included Brief Resilience, Perceived Stress, and Satisfaction with Life Scales. Students were prompted to indicate how worthwhile they found course components and comment on why they rated each component the way they did. Wellbeing results were assessed using paired t-tests with Bonferroni correction for multiple comparisons. Thematic analysis was used to interpret qualitative results. RESULTS/ANTICIPATED RESULTS: Students improved across all wellbeing measures at the program conclusion, including resilience (mean difference(SE) pre- to post-program +0.22(0.06) p=0.0007), perceived stress (-1.71(0.66) p=0.0116), and life satisfaction (+1.57(0.52) p=0.0037). Gains in resilience were maintained 3 months out (pre-program to 3 month survey +0.28(0.06) p<0.0001). To our surprise, mindfulness was the highest rated component of the research program with 85% (121/142) of students rating the mindfulness component ‘extremely’ or ‘quite worthwhile.’ At 3 months, 81% (74/91) reported continued use of one or more skills learned in the mindfulness sessions. Student comments endorsed the perceived importance of interactive mindfulness and dialogue sessions to the program and to careers in biomedical science and research. DISCUSSION/SIGNIFICANCE OF FINDINGS: Our results support the use of interactive mindfulness and dialogue programming as a participant supported, evidence-based approach to strengthen the resilience of undergraduate students pursuing careers in biomedicine. In the future, booster programming may be considered to maintain improvements in perceived stress and life satisfaction.

OBJECTIVES/GOALS: Language is the main barrier to equitable access of neuropsychological resources. In our preliminary study, using an Arabic translation of the Global Neuropsychological Assessment (GNA), we assessed 27 Arabic-speaking participants and compared them to English-speaking controls. Our goal was to assess the Arabic GNA’s validity and feasibility. METHODS/STUDY POPULATION: The Global Neuropsychological Assessment (GNA) is a brief 15-minute assessment of cognition. 27 Arabic-speaking participants were recruited and assessed with the GNA and an Arabic translation of the Montreal Cognitive Assessment (MoCA) by community health workers (CHWs). 17 English-speaking participants GNA data were gleaned from a previous validation study and compared to the Arabic sample via independent samples t-tests. Correlations between the GNA sub-tests and Arabic-translated MoCA are reported in the Arabic-speaking sample. RESULTS/ANTICIPATED RESULTS: ): Independent samples t-tests revealed that Arabic and English-speaking groups significantly differed on education (Arabic: M = 10.3, SD = 3.4, English: M = 15.4, SD = 2.43 t(41) = 6.2, p < .05) but not age (p > .05). A one-way ANCOVA model controlling for education revealed that Arabic and English-speaking groups were not significantly different in any GNA subtest (all p’s > .05) except for the perceptual comparison task (Arabic: M = 22.4, SD = 6.9, English: M = 38.4, SD = 9.9, p < .05). Arabic GNA subtests correlated with each other as expected. Logical memory delayed recall was modestly correlated with the MoCA total score (r = .386, p < .05). DISCUSSION/SIGNIFICANCE: Our preliminary results suggest that the Arabic translation of the GNA is suitable for assessment of Arabic-speaking individuals. Brief educable assessments like the Arabic GNA are essential to meet the needs of these English new language populations and reduce the need for live translations that reduce the reliability of assessment.

OBJECTIVES/SPECIFIC AIMS: N/A. METHODS/STUDY POPULATION: Over a million people gained insurance in Los Angeles (LA) County under the Affordable Care Act (ACA). The vast majority gained Medicaid—government sponsored insurance with low-cost sharing. LA County also made significant investments in the safety net including a program called MyHealthLA, which provides primary and tertiary care for the residually uninsured including poor undocumented individuals at specific sites. Despite this insurance expansion, approximately 3 quarters of a million people in the county remain uninsured. Regardless of insurance status, nearly a quarter of LA County residents reported having difficulty obtaining needed medical care, and among those making less than the poverty level, 43% had difficulties. There is still much to understand about barriers to obtaining insurance and accessing healthcare in Los Angeles in the post-ACA era. Our primary objective was to understand how safety net patients are obtaining, maintaining and using their insurance after the ACA. Specifically we hope to understand the barriers and drivers of these three processes. RESULTS/ANTICIPATED RESULTS: We conducted a qualitative study of 34 safety net patients with 3 different insurance types in LA County. We conducted in-person interviews with adult patients (ages 18–64 years), who had either MediCal, MyHealthLA, or were unsinsured. Our interview guide was based on existing literature, a previous qualitative study conducted in Massachusetts and input from experts in the field. We pilot tested our interviews in English and Spanish and then recruited our participants from 3 sites: LAC+USC (a publically funded county hospital), The Wellness Center (a resource center for safety net patients), and White Memorial Medical Center (a private safety net hospital). We approached patients in the ED and urgent care waiting rooms and obtained informed consent for this IRB approved study. We excluded patients who were non-English and non-Spanish speaking or too ill to interview. We recorded interviews, which were then transcribed and translated into English by a contracted agency. We analyzed our interviews using a framework approach, which included a set of a priori codes from the literature as well as emerging codes from patient responses. We will check a sample of our transcripts for coding consistency (aiming for an inter-rater reliability of >80%). DISCUSSION/SIGNIFICANCE OF IMPACT: We recruited a diverse group of patients that were demographically representative of those who gained insurance under the ACA (childless adults making less than 138% of the Federal Poverty Level). Our preliminary results (based on 17 transcripts), suggest that patients, regardless of insurance type have difficulty accessing primary care. We identified seven domains under the broader theme of barriers to accessing primary care: finding a primary care clinic or physician (PCP), getting timely appointments, geography and transportation, continuity of care, using the Emergency Department (ED) or urgent care as a PCP, switching PCPs or clinics, and cost or coverage.

OBJECTIVES/SPECIFIC AIMS: Determine whether children with solid tumors maintain intact protective immunity to live vaccines during cancer therapy and after completing cancer therapy (postTx). METHODS/STUDY POPULATION: We will perform a prospective cohort study of children with solid tumors (Hodgkin lymphoma, brain, Wilms, and germ cell tumors) followed at the Puerto Rico’s University Pediatric Hospital. Protective immunity will be measured with antibody titers against live vaccines (Measles, Mumps, Rubella, and Varicella) at diagnosis, during cancer therapy, upon completion and 3 months postTx. RESULTS/ANTICIPATED RESULTS: We hypothesize that those patients with protective immunity to live vaccines prior to cancer therapy will lose it at the end of therapy. DISCUSSION/SIGNIFICANCE OF IMPACT: Loss of protective immunity to live vaccines has been reported in patients with hematologic malignancies after cancer therapy. This lack of protective immunity, which puts patients at higher risk of acquiring vaccine preventable diseases, has been limited studied in patients with solid tumors. The Center for Diseases Control has been established that it is safe to immunize cancer survivors with live vaccines 3 months post Tx. However, no clear guidelines for revaccination have been provided for this population. Understanding the protective immunity variation against live vaccines in children with solid tumors will allow us to identify the need for revaccination with live vaccines in this vulnerable population.

OBJECTIVES/GOALS: Clinical trials are the gold standard for developing evidence-based medicine. However, 20% of pediatric randomized clinical trials are discontinued and about 30% of completed trials go unpublished. (Pica and Bourgeois, 2016) Although patient recruitment is the most cited barrier to completing clinical trials, trials funded by academia are more likely discontinued compared to those funded by industry. This study is an attempt to gain additional insights into clinical trials in academic pediatrics. METHODS/STUDY POPULATION: Junior pediatrics faculty (Instructors and Assistant Professors) were recruited to participate in an online survey through RedCAP. The physicians were asked if they had prior experiences with clinical trials and whether they have interest in participating in clinical trials. Those interested were asked three additional questions: what role they were interested in, barriers to participating and interventions they thought would educate them about participating in clinical trials. RESULTS/ANTICIPATED RESULTS: Ninety two (92) out of 119 (77%) junior pediatrics faculty completed the survey. Twenty (20) pediatric subspecialties were represented and respondents were on various academic pathways. A third of the respondents (35%) had previously participated in clinical trials. A majority of the faculty respondents (84; 70%) are on the clinical educator pathway. The 13 respondents who were not interested in clinical trials indicated their preference for patient care, education and quality improvement. Of those interested in clinical trials, the top three preferred roles were site co-investigator (68%), help designing future protocol (47%) and site principal investigator (44%). Other than time, the top barriers to participation were a lack of awareness of what it takes to lead or engage in clinical trials (53%) and a lack of training on clinical trials (45%). Mentoring from an experienced clinical trialist emerged as the top preferred intervention (78%). DISCUSSION/SIGNIFICANCE OF IMPACT: Although limited to one institution, the findings of this study provide insights into pediatric faculty interest in clinical trials. If academic pediatricians are provided with mentoring, there could be an uptick in completed and published clinical trials involving pediatric populations.

OBJECTIVES/GOALS: Speech production requires mapping between sound-based and motor-based neural representations of a word – accomplished by learning internal models. However, the neural bases of these internal models remain unclear. The aim of this study is to provide experimental evidence for these internal models in the brain during speech production. METHODS/STUDY POPULATION: 16 healthy human adults were recruited for this electrooculography speech study. 20 English pseudowords were designed to vary on confusability along specific features of articulation (place vs manner). All words were controlled for length and voicing. Three task conditions were performed: speech perception, covert and overt speech production. EEG was recorded using a 64-channel Biosemi ActiveTwo system. EMG was recorded on the orbicularis orbis inferior and neck strap muscles. Overt productions were recorded with a high-quality microphone to determine overt production onset. EMG during was used to determine covert production onset. Neuroimaging: Representational Similarity Analysis (RSA), was used to probe the sound- and motor-based neural representations over sensors and time for each task. RESULTS/ANTICIPATED RESULTS: Production (motor) and perception (sound) neural representations were calculated using a cross-validated squared Euclidean distance metric. The RSA results in the speech perception task show a strong selectivity around 150ms, which is compatible with recent human electrocorticography findings in human superior temporal gyrus. Parietal sensors showed a large difference for motor-based neural representations, indicating a strong encoding for production related processes, as hypothesized by previous studies on the ventral and dorsal stream model of language. Temporal sensors, however, showed a large change for both motor- and sound-based neural representations. This is a surprising result since temporal regions are believed to be primarily engaged in perception (sound-based) processes. DISCUSSION/SIGNIFICANCE: This study used neuroimaging (EEG) and advanced multivariate pattern analysis (RSA) to test models of production (motor-) and perception (sound-) based neural representations in three different speech task conditions. These results show strong feasibility of this approach to map how the perception and production processes interact in the brain.

OBJECTIVES/SPECIFIC AIMS: In an effort the increase awareness and enhance knowledge and skills in relation to communication in science at Mount Sinai, the Communication in Science summer workshop series aimed to provide an accessible, workforce-wide lecture series to promote key concepts and skills related to communicating science. Delivered by faculty and invited speakers, a series of seven workshops delivered over a 4 week period covered topics such as communication in teams, storytelling and TED talk principles, and community engagement. The aim of each session was to offer “top tips” that participants could apply to their practice. Evaluation of the workshop series aimed to determine participant satisfaction and self-perceived changes in knowledge and skills in relation to science communication. METHODS/STUDY POPULATION: A total of 375 participants registered to attend the workshop series from a range of backgrounds including post-docs, faculty, residents, staff and students at Mount Sinai. Attendance at the workshops ranged from a high of 119 and a low of 33 participants, with as many as 41% of attendees joining the session via live-streaming. Participants were emailed an online survey at the end of the workshop series, asking for satisfaction feedback on each individual workshop and an overall impression of the workshop series. Participants were asked to rate the satisfaction criteria related to content, gained knowledge and skills, presentation style and whether they found the session of value for each workshop, using a Likert scale from 1 - 5 (1 = strongly disagree, 5 = strongly agree). Participants were also asked to provide an overall rating for the summer workshop series as a whole. RESULTS/ANTICIPATED RESULTS: A total of 35 participants responded to the survey. Mean responses to the survey questions were:. The content of this session is important to my work = 4.09 (range 3.77 – 4.45). This session increased my knowledge or skills 4.03 (range 3.56- 4.62). The presenters delivered this content clearly = 4.16 (range 3.78 – 4.67). Overall I found this session valuable = 4.13 (3.78 – 4.61) Participants were also asked to provide an overall rating for the summer workshop series as a whole on a scale of 1 to 10 (1 = poor, 10 = excellent). The mean response was 8.36, indicating a high level of satisfaction with the program. Qualitative feedback indicated that the sessions were successful in increasing awareness of this topic. One participant reported that “these sessions inspired me to think differently, and in a way that can potentially allow me to communicate with the non-science community”. DISCUSSION/SIGNIFICANCE OF IMPACT: The high number of registrants for this summer workshop series indicates a perceived need for education and training on Communication in Science at Mount Sinai. Sessions that focused on TED talk principles and storytelling in science were particularly well attended and well-reviewed, suggesting a particular interested in these topics. There was, however, a discrepancy between registration and attendance numbers, which going forward we will seek to better understand. One explanation is that recording and posting the sessions on YouTube allowed participants to review content asynchronously at a time and location convenient to them, which may have deterred people from attending in person. Following the popularity of this program, future plans are underway to provide an ongoing program of learning in relation to Communication in Science.

OBJECTIVES/GOALS: Historically, Latino farmworkers have lacked access to healthcare. 1 Telehealth promises to bridge this gap in hardly-reached populations. 2 We evaluated the impacts of ACTIVATE, a community-engaged project co-developed withcommunityp artnersAmplaHealth, and a local grower. METHODS/STUDY POPULATION: Mixed-methods outcome evaluation included attitudes survey, knowledge tests, attendance records, exit interviews, and participant observations. Attitudes survey, based on the Unified Theory of Acceptance and Use of Technology (UTAUT) model 3, measured Latino farmworkers’ telehealth acceptability. Pre/Post knowledge tests measured participant knowledge gained on telehealth and mental health services. Semi-structured exit interviewsidentifiedthe impacts of incentives, Promotora training, and health education curricula on participants and community partners. Structured participant observation as certained the level of participant engagement and Promotora facilitation skills. RESULTS/ANTICIPATED RESULTS: Results [https://drive.google.com/file/d/1jQpQdDM3dIR_PzMc1xXPh45Jvz8uBka6/view] On what aspects of the project worked well: “This project really helped us… to make it a priority, to do [health education] workshops. When I was hired, we went out to a few farms and shared information about our services, but it wasn’t anything hugely structured like what you proposed. We hadn’t done a whole lot of Promotora health education prior to this project.” -Ampla Health Administrator The most significant change observed: “Their attitudes… I feel that the very first session, I saw how they were more laid back, not really answering questions, just listening to us. And then the second one… they were more talkative and the very last one they were more comfortable sharing.” -Promotora DISCUSSION/SIGNIFICANCE: Attendence and participant engagement increased over time. Results from the evaluation point to greater telehealth acceptability among participants, increased health education capacity among Ampla Health, and farm worker cohesiveness at the workplace.
