OBJECTIVES/GOALS: #NAME? METHODS/STUDY POPULATION: Cell culture & protein identification: human T cells were purified from healthy blood, then activated & cultured for 5d. CAR-T cells were collected from infusion bags of cancer patients undergoing CAR-T. Silver staining of naive & activated healthy T-cell lysates was compared; B-II spectrin was upregulated and confirmed by Western blot. Migration assays: naive & activated T-cells were imaged during migration on ICAM-1 and ICAM-1 + CXCL12 coated plates. T-cells were transfected with BII-spectrin cDNA & the chemokine dependence of migration was compared with controls. In-vivo studies: in a melanoma mouse model, BII-spectrin transfected or control T-cells were injected; tumors were followed with serial imaging. Human patient records were examined to correlate endogenous BII-spectrin levels and CAR-T response. RESULTS/ANTICIPATED RESULTS: Activated T-cells downregulate the cytoskeletal protein B-II spectrin compared to naive cells, leading to chemokine-independent migration in in vitro assays and off-target trafficking when CAR-T cells are given in vivo. Restoration of B-II spectrin levels via transfection restores chemokine-dependence of activated T-cells. In a mouse melanoma model, control mice injected with standard activated T-cells showed fewer cells in the tumor site and more cells in the off-target organs (spleen, lungs) when compared to mice injected with B-II spectrin transfected cells. Furthermore, among 3 human patients undergoing CAR-T therapy, those with higher endogenous B-II spectrin levels experienced fewer side-effects, measured by the neurotoxicity and cytokine release syndrome grades. DISCUSSION/SIGNIFICANCE: A major hurdle to widespread CAR-T therapy for cancer is significant, often fatal side-effects. Our work shows that the protein B-II spectrin is downregulated during CAR-T production, and that restoring B-II spectrin levels decreases side-effects while increasing tumor clearance--hopefully translating to better CAR-T regimens for the future.

OBJECTIVES/SPECIFIC AIMS: The objective of this research was to assess the clinical impact of simulation-based team leadership training on team leadership effectiveness and patient care during actual trauma resuscitations. This translational work addresses an important gap in simulation research and medical education research. METHODS/STUDY POPULATION: Eligible trauma team leaders were randomized to the intervention (4-hour simulation-based leadership training) or control (standard training) condition. Subject-led actual trauma patient resuscitations were video recorded and coded for leadership behaviors (primary outcome) and patient care (secondary outcome) using novel leadership and trauma patient care metrics. Patient outcomes for trauma resuscitations were obtained through the Harborview Medical Center Trauma Registry and analyzed descriptively. A one-way ANCOVA analysis was conducted to test the effectiveness of our training intervention versus a control group for each outcome (leadership effectiveness and patient care) while accounting for pre-training performance, injury severity score, postgraduate training year, and days since training occurred. Association between leadership effectiveness and patient care was evaluated using random coefficient modeling. RESULTS/ANTICIPATED RESULTS: Sixty team leaders, 30 in each condition, completed the study. There was a significant difference in post-training leadership effectiveness [F(1,54)=30.19, p<.001, η2=.36] between the experimental and control conditions. There was no direct impact of training on patient care [F(1,54)=1.0, p=0.33, η2=.02]; however, leadership effectiveness mediated an indirect effect of training on patient care. Across all trauma resuscitations team leader effectiveness correlated with patient care (p<0.05) as predicted by team leadership conceptual models. DISCUSSION/SIGNIFICANCE OF IMPACT: This work represents a critical step in advancing translational simulation-based research (TSR). While there are several examples of high quality translational research programs, they primarily focus on procedural tasks and do not evaluate highly complex skills such as leadership. Complex skills present significant measurement challenges because individuals and processes are interrelated, with multiple components and emergent nature of tasks and related behaviors. We provide evidence that simulation-based training of a complex skill (team leadership behavior) transfers to a complex clinical setting (emergency department) with highly variable clinical tasks (trauma resuscitations). Our novel team leadership training significantly improved overall leadership performance and partially mediated the positive effect between leadership and patient care. This represents the first rigorous, randomized, controlled trial of a leadership or teamwork-focused training that systematically evaluates the impact on process (leadership) and performance (patient care).

ABSTRACT IMPACT: This work will help to identify ways to adapt family-based obesity treatment based on families’ food purchasing behaviors and beliefs. OBJECTIVES/GOALS: Families in obesity treatment are encouraged to make dietary changes. Dietary changes are impacted by food choices, which can be influenced by food cost. The objective of this research is to explore families’ food purchase behaviors and beliefs from the perspective of their health coach, and to assess how health coaches adapt treatment to address these. METHODS/STUDY POPULATION: Semi- structured telephone interviews were conducted with 10 health coaches in the Effectiveness of Family-Based Weight Loss Treatment Implementation in Primary Care (PLAN) study across four geographic locations in MO, NY, and OH. Topics covered were professional background, perspectives on working with families, and discussions with families regarding cost perception and food choice. Conventional content analysis was used through ‘open-coding’ of transcribed text by reading the transcripts and assigning labels. Codes were then organized into themes. In addition to the interviews, coaches were asked to complete a FRAME checklist to identify adaptations or modifications that were made to the treatment. RESULTS/ANTICIPATED RESULTS: The coaches reported that cost is a barrier to making healthier food choices for some but not all of their FBT families. Themes for cost as a barrier include: fast food is cheaper; justification to choose old food choices; sales on foods high in calories and sugar; bulk buying; and fewer sales on healthier options. Themes for what families consider when purchasing healthier items include: perishable foods, increased waste, picky kids, lack of knowledge about healthy eating on a budget, afraid of including new foods, and no money for new foods. The final stage of content analysis for the FRAME schematic checklist is ongoing. DISCUSSION/SIGNIFICANCE OF FINDINGS: The results exemplify that families’ have different food purchasing behaviors and beliefs and consider a variety of factors when making food choices. The data gathered from the FRAME checklists will help in characterizing the adaptations or modifications made by coaches and allow for better understanding of the impact on the families.

Objectives/Goals: Academic research centers struggle to recruit and retain a diverse, competent clinical and translational science (CTS) workforce. The clinical research professional career pathway is particularly underrecognized among undergraduates, despite offering multiple career opportunities. Methods/Study Population: To address these challenges, two undergraduate outreach programs were developed. First, an undergraduate certificate program in CTS (UC-CTS) was designed to equip students with the skills and knowledge needed to enter the workforce immediately after graduation. Second, a “CTS Roadshow” was launched to build awareness of CTS careers within a variety of undergraduate programs and majors. In this recruitment initiative, principal investigators (PIs) and CRPs visit classrooms to share information about CTS career pathways and offer insights into the roles, responsibilities, and professional opportunities available in the field. Results/Anticipated Results: The UC-CTS program launched in Fall 2024 as a 12-credit certificate that includes two paid internships: one in patient care and one in research. Currently, the program has 5 students enrolled with an anticipated increase in enrollment to 20 students by Spring 2025. Similarly, the CTS Roadshow has reached an increasing number of students each year. Since its inception in Spring 2023, the CTS Roadshow has introduced over 750 undergraduates across 21 courses to CTS careers. The CTS Roadshow has engaged students from a variety of majors, including biology, psychology, medical sciences, legal, finance, accounting, and pre-health programs, increasing awareness of and interest in CTS careers. Discussion/Significance of Impact: Both programs aim to expose students to CTS careers early in their education, better preparing them for full-time CTS roles after graduation. A rise in qualified applicants pursuing CTS careers locally and regionally is expected, improving job satisfaction and retention through enhanced preparation for the career field.

OBJECTIVES/GOALS: This study engaged Black adults who reside in a rural area of Kentucky to explore their beliefs, norms, knowledge, attitudes, and health-related behaviors about Alzheimer’s disease (AD) (RQ1) and what message elements are most relevant for designing a health message aimed at encouraging them to get screened for AD (RQ2). METHODS/STUDY POPULATION: This qualitative study was guided bythe Integrative Model of Behavior. Participants were recruited from a faith-based institution in rural Kentucky. Black adults aged 50+ years were invited to participate in the study, which consisted of two focus groups. Group 1 gained information about behavioral determinants (RQ1) and examined which message design elements were important to Black adults by asking for feedback on a handout from the Alzheimer’s Association that encouraged AD screening (RQ2). The handout was redesigned based on feedback from Group 1. Group 2 was involved in a discussion of the redesigned handout, asking for further feedback. Focus groups were audio recorded and transcribed verbatim. Data analysis included thematic analysis of transcripts of the focus groups and quantitative analysis. RESULTS/ANTICIPATED RESULTS: Participants (N=18) were all female and Black with a mean age of sixty-two years. For RQ1, Results revealed that 1) limited knowledge of AD led to feelings of not being able to do anything about the disease, whereas awareness and education led to hope; 2) past healthcare experiences informed subsequent beliefs and behaviors, and 3) culture impacted beliefs, with a cultural norm of “what happens in our house, stays in our house” being prominent. For RQ2, results revealed the importance of regionally specific messaging for AD. Generic statements that applied broadly did not appeal to participants. Message delivery, layout, and format for low literacy individuals are key for maximizing audience impact. Pictures give hints about the message and aid in understanding. DISCUSSION/SIGNIFICANCE: Barriers such as past experiences, lack of knowledge, and cultural norms negatively impact the likelihood that Black adults will get screened for AD, resulting in delayed healthcare or healthcare avoidance. Regionally specific health messaging for AD has the potential to encourage modifications in health-related behaviors.

OBJECTIVES/GOALS:

• Develop strong network of science teachers interested in promoting scientific research to their students.

• Place students in an immersive summer research internship that, when possible, matches their career interests.

• Expose students to the numerous career paths within the STEM field.

METHODS/STUDY POPULATION:

• The program recruits socio-economically disadvantaged students and provides them a stipend, and also accepts students who can participate unpaid.

• Local school teachers are engaged in a summer fellowship to learn biotechnologies and research. In Spring these teachers help recruit students and during the subsequent Fall help students with college and scholarship applications.

• Students are placed in a variety of laboratories within the Schools of Medicine, Science, Dentistry, Public Health, Informatics, Health and Human Sciences, Engineering and Technology, especially in biomedical engineering. Students are also placed in industry laboratories such as Eli Lilly and the Indiana Bioscience Research Institute.

• Long-term program follow-up is done through post-internship surveys to assess impact on graduate and professional school admission.

RESULTS/ANTICIPATED RESULTS:

• Since the Indiana CTSI was established in 2008, 872 students have participated in the summer internship.

• 71% of past interns are underrepresented minorities in science or classified as disadvantaged by NIH criteria.

• 17% of students interned during grade 10, 72% during grade 11, and 11% during grade 12.

• 21% of students engage in the program for more than one year.

• 100% of past interns are currently enrolled in or have graduated college.

• Over 60% of those with a bachelors degree proceed to graduate and professional schools and over 80% stay in STEM related fields. These rates are equal for interns from underrepresented minorities or those classified as disadvantaged by NIH criteria.

DISCUSSION/SIGNIFICANCE OF IMPACT:

• Students engaged in the Indiana CTSI STEM program are progressing through the translational science pipeline based on their graduating from college and remaining in the STEM field.

OBJECTIVES/GOALS: Evaluate if exposure to violence is associated with post-partum weight retention among WIC participants, which can lead to overweight/obesity due to metabolic adaptations associated to new adapted weight. If confirmed, it would highlight the need for revision of screening for violence exposure as social determinant of health among participants. METHODS/STUDY POPULATION: Nested cohort study among women enrolled in the Baby Act Trial (BAT) who have been enrolled to the active study phase and completed the Accountable Health Communities Health Related Social Needs survey from the Centers for Medicare & Medicaid services as the source of evidence of exposure to violence. BAT recruitment engaged women in their third trimester who were active participants of the Puerto Rico Women, Infants and Children Program (PRWIC), and planned to enroll their infant in the program. Anthropometric measures were documented at the following time points: prior to pregnancy, at delivery, and 12 months post-partum. Of the 530 women recruited to the study, 291 have completed study measures for inclusion into this exploratory analysis from this ongoing trial. RESULTS/ANTICIPATED RESULTS: A Total of 301 participants have met the criteria for inclusion in this preliminary analysis. Mean age among mothers was 26.5 years (SD 5.3), 46.6% had High School level education attainment or less, and 43.3% were actively working at the time of recruitment. Twelve percent of participants had BMI above 35 at 6 months post-partum, while the prevalence of violence exposure was reported as follows for each type of encounter: 3.3% responded yes to physical violence by friends of family, 9.7% reported exposure to insults or inappropriate treatment by any person including family or friends, 2% having been threatened by anyone including family or friends, 6.3% reported having been yelled/cursed at or insulted by anyone including family or friends. Even more concerning is that 7.5% reported severe social vulnerability. DISCUSSION/SIGNIFICANCE: Results reveals importance of providing integrated care in social assistance program. Participants belongs to vulnerable population with social determinants of health that affect the health care they receive. It shows that providing nutritional assistance it’s not enough to being healthy because other components also play a role in overall health.

Despite increasing attention to the importance of diverse research participants, success across the translational research spectrum remains limited. To assess investigator and research team training needs, we conducted a web-based survey exploring barriers in knowledge and practice. Respondents (n = 279) included those affiliated with the University of Wisconsin Institute for Clinical and Translational Research (ICTR). Although all respondents reported an abstract belief in the importance of diversity, factors associated with higher levels of best practices knowledge and implementation included: (1) use of federal funding; (2) having fewer years of experience; (3) recruiting healthy participants; and (4) having recruitment training.

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

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

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

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

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

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

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

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

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

RESULTS/ANTICIPATED RESULTS:

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

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

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

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

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

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

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

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

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

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

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