OBJECTIVES/GOALS: Breast cancer survivors who experience psychological and physical symptoms after treatment ends have an increased risk for comorbid disease development, reduced quality of life, and premature mortality. However, survivors in satisfying marriages report lower stress and better health than those in dissatisfying marriages. METHODS/STUDY POPULATION: Research is needed to identify how survivors’ marriages provide these health benefits across the cancer continuum. Including both survivors and their partners’ perspectives can identify key pathways connecting relationships to better health. This study examined survivors’ and their partners’ psychological, physical, and relational health. Breast cancer survivors (stage 0-III) and their partners (n=34 individuals, 17 couples) completed a baseline online survey followed by a 7-day diary study with three ecological momentary assessments across the day. Questionnaires assessed their cancer-related communication, relationship distress, and psychological and physical symptoms. RESULTS/ANTICIPATED RESULTS: Survivors reported poorer sleep quality and greater fatigue than their partners. Survivors also reported disclosing more thoughts, feelings, and information about cancer compared to their partners. For both survivors and partners, feeling more satisfied with each other’s cancer-related discussions and reporting lower relational distress correlated with fewer physical symptoms, sleep problems, fatigue, and psychological distress. DISCUSSION/SIGNIFICANCE: For both survivors and their partners, feeling more satisfied with how often they talked about survivorship and the cancer experience was associated with better psychological and physical health. This research demonstrates the health benefits and importance of open communication for both survivors and their partners across the cancer continuum.

OBJECTIVES/SPECIFIC AIMS: The aim of this program is to provide early support to motivated medical students interested in a career as a physician-scientist in a framework of competency-based medical education. The CTSA creates an opportunity to provide clinical research education and protected time for research for medical students in clinical and translational research. METHODS/STUDY POPULATION: This physician-scientist experience offers research opportunities in a wide variety of research disciplines, focused on clinical and translational investigations. The program offers both five-month and one-year blocks of protected research time. The five-month option is integrated into the four- year medical curriculum. The one-year option requires enrollment in an established Master of Clinical Research degree. Both options provide research experience under the mentorship of a physician-scientist. The five-month option aligns with UME competencies categorized under the six ACGME Domains of Competence. The one-year option includes coursework in research design, biostatistics, research ethics, data management, scientific communication, and proposal development within the CTSA-based education program. All students in the program attend a bimonthly journal club and seminar series starting in year one and extending through the research experience. This includes discussion of the importance of mentorship, selecting a residency, scientific writing and presentation, and personal narratives of physician-scientists and their pathways to this career. All students will be followed to determine career outcome. RESULTS/ANTICIPATED RESULTS: Between 2015 and 2018, 67 students entered the program 46% selected the year out, and 56% selected the 5-month option. Students selecting this program constitute about 10% of the medical student population overall. We have had 17 graduates of the program to date. 55% of the cohort is women which parallels the OHSU medical student population. Long-term follow-up of at least 10 years will be needed to determine career outcomes. We assess student productivity by traditional measures of submitted abstracts, manuscripts, and presentations as well as longer term outcomes such as career orientation in medicine such as entry into a research-oriented residency and ultimately into an academic medicine or research. DISCUSSION/SIGNIFICANCE OF IMPACT: The OHSU physician-scientist experience successfully matches medical students with a diverse set of research mentors focused on the CTSA. Although institutional structures determine the variety of specific research opportunities, the integration of physician-scientist training into a CTSA-based training program expands the reach of training programs such as the TL1.

OBJECTIVES/SPECIFIC AIMS: To create a composite index, referred to as the Pediatric Hydrocephalus Severity Index (PHSI), to classify the severity of disease at baseline and predict outcomes among children treated for hydrocephalus. METHODS/STUDY POPULATION: The Hydrocephalus Outcome Questionnaire will be administered in person or online to the parents of 150 patients between the ages of 5 and 18 years who are followed at the Neurosurgery Clinic at St. Louis Children’s Hospital for hydrocephalus. Patients must have been diagnosed and treated for hydrocephalus at least 6 months prior to the survey date. Potential participants are excluded if their health status changed during the 4 weeks prior to survey date, as determined by the child’s parents. Potential risk factors (see anticipated results) will be identified on retrospective medical record review. We will create a clinical prediction rule, called the PHSI, to stratify patients on likelihood of experiencing a poor long-term outcome after surgical treatment. Participants will be classified as “good” or “poor” outcome based on thresholds set for questionnaire results. We will use a combination of bivariate analysis and clinical reasoning to restrict the number of factors for further analysis, and multivariate logistic regression to build a predictive model for poor outcome. Creation of the PHSI will involve assigning integer values to adjusted odds ratios for significant risk factors at a 95% confidence level. RESULTS/ANTICIPATED RESULTS: Risk factors that we anticipate will be predictive of long-term clinical outcome include signs and symptoms at onset (bulging fontanel, splayed sutures, papilledema, up-gaze palsy, headache, vomiting, lethargy), head circumference above the 97th percentile, frontal-occipital horn ratio greater than 0.4, etiology of meningitis or neonatal intraventricular hemorrhage, central nervous system comorbidities (seizures, Chiari malformation, scoliosis, periventricular leukomalacia), preoperative infection or sepsis, and frequent shunt revisions or infections. We hypothesize that a PHSI will be a valuable tool for stratifying patients in future research studies, as well as aiding prognosis in clinical situations. DISCUSSION/SIGNIFICANCE OF IMPACT: A validated composite PHSI would be a major advance in clinical hydrocephalus research and practice. A PHSI would allow investigators to stratify patients based on initial presentation for clinical research studies, which may in turn lead to the establishment of more standardized treatment guidelines. It would also facilitate studies investigating differential utilization of healthcare resources based on disease severity. Clinically, a PHSI would better equip physicians to counsel parents on what to expect for their child or future healthcare resource requirements.

OBJECTIVES/GOALS: Results of a formative evaluation of the CardioPulmonary Vascular Biology (CPVB) COBRE will be presented. Of interest were the quality of the overall program, satisfaction with training, mentoring, and services offered, mechanisms for communication, and effectiveness of the collaboration between junior investigators and their mentors. METHODS/STUDY POPULATION: Integral to this evaluation was the creation of questionnaire for junior investigators to complete that addressed four domains: 1) relationship with their mentor, 2) research self-efficacy, 3) administrative and specialty cores value, and 4) satisfaction with events and operations of the COBRE. The two co-principal investigators, program manager, and evaluator developed the 34 items comprising this instrument. The questionnaire was administered online and all eight of the current junior investigators completed the questionnaire. RESULTS/ANTICIPATED RESULTS: Participants were mostly satisfied with the mentoring they were receiving and the operational services of the Administrative and Lab Cores. In terms of training preparedness, these participants felt they were not as prepared as they would like for making adequate progress as an academician and did not feel prepared for managing a lab. Interestingly, these participants felt they were most prepared to develop collaborations with scholars and professionals from other disciplines, but stated they felt they were not as prepared in their abilities to build scientific collaborations. DISCUSSION/SIGNIFICANCE OF IMPACT: Because a primary foci of COBRE grant mechanisms is the development of junior level investigators, evaluating their skills, mentoring experiences, and the usefulness of services is paramount to the sustainability and collaborative research environments of COBREs. This evaluation serves as a model for other COBREs as a tool for measuring this goal.

OBJECTIVES/GOALS: We seek to describe the challenges to mental healthcare access and utilization among Somali refugees in Minnesota. The objectives of this study are 1) to characterize beliefs and attitudes about mental illness and 2) identify barriers, either personally experienced or perceived, to utilizing mental health services among Somali refugees. METHODS/STUDY POPULATION: Mental health challenges are of particular concern among Somali refugees, who have been found to have rates of PTSD as high as 50%. However, Somali refugees are reported to underutilize mental healthcare. We will recruit 20-25 Somali refugee women and men, who are 18 years or older and reside in the Twin Cities, to participate in one on one interviews. Participants will be asked about their perception of barriers to mental healthcare services, and their beliefs about mental illness and treatment. We will transcribe the interviews, code them, and identify key themes. A community advisory board will be directly involved in the research design, recruitment, interview instrument development, interpretation of findings, and dissemination of project materials as part of our community engagement protocol. RESULTS/ANTICIPATED RESULTS: When completed we expect to identify mental health beliefs and barriers to mental healthcare utilization. The long-term goal of this work is to reduce the substantial mental health morbidity among Somali refugees. Common barriers to research participation that we expect are mistrust, financial constraints, fear of unintended outcomes, stigma about participating in research, and fear of deportation or concern of immigration status. We plan to address these barriers by hiring bilingual Somali recruiter/interviewer, translating study materials, reassuring confidentiality of participant’s information, providing a $50 incentive, and implementing community advisory board’s input on study design and recruitment sites. DISCUSSION/SIGNIFICANCE: Translational Impact: Findings from interviews will be disseminated and evaluated by members of the community and providers. Recommendations based on our findings can be applied in mental healthcare practice to reduce identified barriers. Community dissemination can also promote the destigmatization of mental healthcare in the Somali community.

OBJECTIVES/GOALS: We describe the transition of ShAred Resource Panels (ShARPs) within the Center for Community Health (CCH) at Northwestern University’s Clinical and Translational Sciences (NUCATS) Institute to virtual sessions and explore ongoing practices. METHODS/STUDY POPULATION: Restrictions placed during the COVID-19 pandemic led to changes in community-engaged health equity research, such as the transition of community and partner-engaged panels from in-person to virtual. ShARPs have occurred since December 2015. The model includes research team members, community members, community co-facilitator, and CCH staff. These custom panels bring together 8-10 community members familiar with a research topic or community of focus, offering feedback on adaptations that can improve research relevance and feasibility. Until the COVID-19 pandemic, all ShARPs were conducted in person. From March 2020 to January 2023, panels occurred virtually. From 2023, the option of virtual or in-person ShARPs has been available. Count data and informal interview data were reviewed. RESULTS/ANTICIPATED RESULTS: The number of ShARPs peaked in 2019 and has remained stable. The first virtual ShARP occurred on April 22, 2020, and all subsequent sessions have been virtual. As of October 2023, 6 ShARPs have occurred, with no research teams pursuing an in-person session despite its availability. Participants described virtual ShARPs as convenient and accessible. Academic teams cited concern about low community member participation should they opt for an in-person session. DISCUSSION/SIGNIFICANCE: It is feasible to conduct ShARPs virtually and is the current preferred modality. Whether virtual ShARPs enhance, neutralize, or detract from the effectiveness of the session is unknown and guides our future work. More research is needed, including discussion, and learning from our CTSA colleagues.

OBJECTIVES/SPECIFIC AIMS: The aim of this study is to examine if stable health insurance coverage is associated with improved type 2 diabetes (DM) control and with reduced racial/ethnic health disparities. METHODS/STUDY POPULATION: We utilized EMR data (2005–2013) from 2 large, urban academic health centers with a racially/ethnically diverse patient population to longitudinally examine insurance coverage, and diabetes outcomes (A1C, LDL cholesterol, BP) and management measures (e.g., A1C and BP monitoring). We categorized insurance stability status during each 6-month interval as 6 separate categories based upon type (private, public, uninsured) and continuity of insurance (continuous, switches, or gaps in coverage). We will examine the association between insurance stability status and DM outcomes adjusting for time, age, sex, comorbidities, site of care, education, and income. Additional analysis will examine if insurance stability moderates the impact of race/ethnicity on DM outcomes. RESULTS/ANTICIPATED RESULTS: Overall, we anticipate that stable health insurance coverage will improve measures for DM care, particularly for racially/ethnically diverse patients. DISCUSSION/SIGNIFICANCE OF IMPACT: The finding of an interaction between insurance stability status and race/ethnicity in improved diabetes management and control would inform the national health care policy debate on the impact of stable health insurance.

Objectives/Goals: Aims are to identify the gaps and discrepancies between cancer care teams at Princess Margaret (PM) and primary care providers (PCPs). To ensure the transition from hospital care at PM into the community integrates the expressed needs of PCPs and cancer specialists. To ensure PCPs have the necessary resources to provide high-quality care to patients. Methods/Study Population: Phase 1 is the preparation phase, which consists of searching the literature and conducting contextual inquiry with experts in relevant fields, such as cancer survivorship and primary care. This phase is crucial to the planning of this project as the information gathered will be used to define the problem space and outline the scope of the project. Next (phases 2 and 3) we aim to create and distribute surveys to PCPs to gather data on current protocols and resources. We plan to distribute this survey by emailing PCPs and accessing PCP networks. Upon completion of the survey, we will review the data and assess which areas need further investigation. Then, we will create an interview guide keeping in mind the areas that need to be supplemented and aiming to validate the need. Results/Anticipated Results: A resource that presents guidelines for PCPs to assist in them taking on follow-up care responsibilities for low-risk cancer survivorship patients. These guidelines may include information such as communication pathways between PCPs and the PM Cancer Care team, expected follow-up care measures, and timeframes for follow-up care. The development of this guideline will assist in alleviating the burden on the PM Cancer Centre system as it will facilitate low-risk patients transitioning back to family care. Discussion/Significance of Impact: There is an increasing demand for oncology services post-cancer treatment at the PM Cancer Centre and the current cancer model follow-up care is not sustainable by oncologists alone. There is a need to explore innovative personalized pathways to follow-up care based on an individual’s needs and integrate family doctors.

OBJECTIVES/GOALS: The SARS-CoV-2 (Severe Acute Respiratory Syndrome CoronaVirus-2), which underlies the current COVID-19 pandemic, among other tissues, also targets the central nervous system (CNS). The goal of this study is to investigate mechanisms of neuroinflammation in Lipopolysaccharides (LPS)-treated mouse model and SARS-CoV-2-infected hamsters. METHODS/STUDY POPULATION: In this research I will assay vascular reactivity of cerebral vessels to assess vascular dysfunction within the microcirculation. I will determine expression of proinflammatory cytokines, coagulation factors and AT1 receptors (AT1R) in isolated microvessels from the circle of Willis to assess inflammation, thrombosis and RAS activity in the microvasculature. LPS and SARS-CoV-2, are both associated with coagulopathies and because of that I will measure concentration of PAI-1, von Willebrand Factor, thrombin and D-dimer to assess the thrombotic pathway in the circulation. Histology and immunohistochemistry will assess immune cell type infiltration into the brain parenchyma, microglia activation and severity of neuroinflammation and neural injury. RESULTS/ANTICIPATED RESULTS: We hypothesize that under conditions of reduced ACE2 (e.g., SARS-CoV-2 infection), AT1R activity is upregulated in the microvasculature. In the presence of an inflammatory insult, these AT1Rs promote endothelialitis and immunothrombosis through pro-thrombotic pathways and pro-inflammatory cytokine production leading to endothelial dysfunction in the microvasculature, blood brain barrier (BBB) injury, deficits in cognition and increased anxiety. We will test this hypothesis through 2 aims: Aim 1: Determine the role of the pro-injury arm of the RAS in the pathophysiology of the brain in animal models of neuroinflammation and COVID-19. Aim 1: Determine the role of the protective arm of the RAS in the pathophysiology of the brain in animal models of neuroinflammation and COVID-19. DISCUSSION/SIGNIFICANCE: This study will provide insights that will complement on-going clinical trials on angiotensin type 1 receptor (AT1R) blockers (ARBs) in COVID-19. This research is a necessary first step in understanding mechanisms of brain pathogenesis that can set the groundwork for future studies of more complex models of disease.

Trauma is a common cause of morbidity and mortality in humans and companion animals. Recent efforts in procedural development, training, quality systems, data collection, and research have positively impacted patient outcomes; however, significant unmet need still exists. Coordinated efforts by collaborative, translational, multidisciplinary teams to advance trauma care and improve outcomes have the potential to benefit both human and veterinary patient populations. Strategic use of veterinary clinical trials informed by expertise along the research spectrum (i.e., benchtop discovery, applied science and engineering, large laboratory animal models, clinical veterinary studies, and human randomized trials) can lead to increased therapeutic options for animals while accelerating and enhancing translation by providing early data to reduce the cost and the risk of failed human clinical trials. Active topics of collaboration across the translational continuum include advancements in resuscitation (including austere environments), acute traumatic coagulopathy, trauma-induced coagulopathy, traumatic brain injury, systems biology, and trauma immunology. Mechanisms to improve funding and support innovative team science approaches to current problems in trauma care can accelerate needed, sustainable, and impactful progress in the field. This review article summarizes our current understanding of veterinary and human trauma, thereby identifying knowledge gaps and opportunities for collaborative, translational research to improve multispecies outcomes. This translational trauma group of MDs, PhDs, and DVMs posit that a common understanding of injury patterns and resulting cellular dysregulation in humans and companion animals has the potential to accelerate translation of research findings into clinical solutions.

Academic Medical Centers strive to create multidisciplinary research teams to produce impactful science. However, few faculty researchers receive training in “team science,” a well-established concept in business research and practice. Responding to demand for assistance developing effective research teams, the Collaboration and Team Science Program of the Clinical and Translational Science Institute (CTSI) at Wake Forest School of Medicine (WFSM) partnered with faculty from the Wake Forest University (WFU) School of Business with expertise in leadership, management, and team building. We initiated a needs assessment, including a written survey from a diverse set of 42 research scientists as well as semi-structured interviews with 8 researchers. In response to identified needs, we developed training sessions and consultations to teach teams to implement two tools known to enhance team dynamics: (1) Team charter, a document that defines the team’s purpose, goals, roles, and strategies; and (2) Responsible, Accountable, Consulted, Informed (RACI) matrix, a table or spreadsheet that clarifies tasks and accountability. Since 2018, 10 teams and over 100 individuals have attended training sessions and 6 teams received personalized team consults. We describe these tools, present a formal analysis of quantitative results, and highlight the next steps being taken in response to these findings.

ABSTRACT IMPACT: This study identifies potential areas for community and clinical interventions to improve eye and vision health. OBJECTIVES/GOALS: The ‘All Eyes on Us’ study sought to understand perceptions of and barriers to eye and vision care, of residents over the age of 40 in the Broadway/Slavic Village neighborhood in Cleveland, Ohio. The goal of this study was to identify potential areas for community and clinical interventions to improve eye health. METHODS/STUDY POPULATION: Residents of the Broadway/Slavic Village neighborhood, an ethnically diverse, low socioeconomic status, neighborhood in Cleveland, Ohio were recruited from, and with the assistance of, University Settlement, a nonprofit that has been providing services to the neighborhood since 1926. The project’s Community Advisory Board assisted with the development of a semi-structured interview guide over the course of three meetings. Sixty interviews were completed, 30 with self-identified European Americans and 30 with self-identified African-Americans, all over the age of 40. Two research team members coded the interview transcripts and a thematic analysis was conducted. RESULTS/ANTICIPATED RESULTS: Participants identified barriers to obtaining eye and vision care for themselves as well as perceived barriers for others, including transportation, cost, insurance status, clinic locations, lack of education around eye and vision care, fear, forgetfulness, and priority management. To encourage people to go to the eye doctor more often, participants mentioned strategies related to access issues including lowering the cost of exams, operating on a sliding scale, improving insurance coverage, transportation services, and having mobile units that deployed to specific neighborhoods or senior centers. Additionally, participants suggested education and increasing awareness about the importance of eye and vision care. DISCUSSION/SIGNIFICANCE OF FINDINGS: Participants in this study identified that accessibility to and awareness about eye health and eye care is an issue. Interventions to address both access issues such as location, cost, and insurance as well as those that increase education could increase engagement with eye and vision care.

OBJECTIVES/SPECIFIC AIMS: -Transmit learning and wisdom from past scholars -Predispose new scholars towards a receptive attitude -Normalize struggle and failure on the road to success -Encourage a community of accomplishment and celebration -Connect the scholar METHODS/STUDY POPULATION: The exit presentations were given by NCATS funded junior faculty in the CTSI KL2 Scholars Program who had graduated. All KL2 Scholars take part in the K Scholar Multidisciplinary Seminar Series that meets weekly during the academic calendar. The departed scholars returned for the presentations the following semester. The audience was made up of KL2 who had started with a later cohort, the CTSI KL2 program is a 3-year program, and newly appointed scholars. Scholars were given 12-15 minutes to cover: 1) What was learned, 2) Accomplishments on specific aims, 3) Next steps for project and career, and 4) Recommendations for other scholars. Presentations were collected and reviewed for recurring themes. Themes were grouped and quotes were included to identify nuance. RESULTS/ANTICIPATED RESULTS: From the 17 exit presentations, six themes were identified: 1) Don’t miss the forest for the trees (x10) – “the KL2 program helps to fill in gaps scholars don’t realize they have – it is about more than just the research project, trust in the process and let the program help keep you on track.” 2) Diversify and keep an open mind (x7) – “focus is important but diversifying research and reorganizing priorities is ok.” 3) Don’t be discouraged by failure (x6) –” perseverance is key, all success comes on the heels of many failures.” 4) Importance of building network inside and outside of Scholar program (x6) – “importance of exploring and establishing collaborations” 5) Learn to say no and yes (x5) – “protect your time but be open to opportunities” 6) Seek advice and criticism but don’t follow blindly (x4) DISCUSSION/SIGNIFICANCE OF IMPACT: The use of exit presentations for graduating KL2 Scholars is a useful tool in transmitting wisdom and enhancing subsequent KL2 cohorts. The Scholar’s experience and trajectory, share personal insights and recommendations to help other Scholars get the most out of their KL2 experience, give the community a chance to celebrate the Scholar’s accomplishments, and provide the Scholar with a sense of closure in their KL2 journey. Within the exit presentations, six common themes emerged relating to best practices on making good use of resources and guidance, and learning to interact and navigate within networks and responsibilities in a mature way. Scholars in the audience benefit from hearing the insights and advice from their predecessors. The identification of themes helps the program to understand where it adds value.

ABSTRACT IMPACT: Leverage community engagement to continue moving translational science and research forward. OBJECTIVES/GOALS: Engaging community in translational research improves innovation and speeds the movement of evidence into practice. Yet, it is unclear how community is engaged across the translational research spectrum or the degree of community-engagement used. We conducted a scoping review to fill this gap. METHODS/STUDY POPULATION: We used the PRISMA model search strategy with a range of databases (e.g., PubMed/Medline, Scopus) to identify articles published between January 2008 and November 2018 (n=167) and eliminated studies that did not use any level of community-engagement (n=102). Studies were coded for translational stage-corresponding to T0 (basic science), T1 (basic science to clinical research in humans; n=6), T2 (clinical efficacy and effectiveness research, n=45), T3 (dissemination and implementation research, n=95), and T4 (population health, n=21) as well as the degree of community engagement from least to most intensive (i.e., outreach, consultation, involvement, collaboration, shared leadership). RESULTS/ANTICIPATED RESULTS: The final number of eligible articles was 65. There was a relatively balanced distribution across levels of community engagement across articles (i.e., outreach, n=14; consultation, n=13; involvement, n=7; collaboration, n=15; shared leadership, n=16). Within these articles, the depth of community engagement varied with higher engagement typically occurring at later stages of translational research (T3 and T4), but more specifically in the dissemination and implementation science stage (T3). However, shared leadership, the most intensive form of engagement, was found in T2, T3, and T4 studies suggesting the value of community-engagement across the translational research spectrum. DISCUSSION/SIGNIFICANCE OF FINDINGS: A strong understanding of how various levels of community engagement are used in translational research, and the outcomes they produce, may to expedite the translation of knowledge into practice and enable practice-based needs to inform policy.

OBJECTIVES/GOALS: The critical role that trust plays continues to be documented and highlights the gap in understanding the extent to which initiatives such as All IN for Health from the Indiana Clinical and Translational Institute (I-CTSI) can improve trust between the community and researchers. We discuss measures of trust and evaluate how we may improve recruitment. METHODS/STUDY POPULATION: In this study, we invited over 13000 volunteers from the All IN for Health research participant registry. Six hundred and sixty-three (663) respondents participated in the survey. The Relationship of Trust and Research Engagement Survey included three validated surveys: Distrust in Healthcare Organizations, the Trust in Medical Researchers scale by Hall et. al, and Patient Trust in Medical Researchers by Mainous et al.. The 36-item survey also included open-text questions. RESULTS/ANTICIPATED RESULTS: Based on preliminary results 74% agreed it’s safe to be in medical research, yet 79% had never been asked to participate in medical research by their doctor. Sixty percent believed that HCOs put money above patients’ needs. Forty percent agreed that doctors do medical research for selfish reasons. Fifty percent disagree that patients get the same medical treatment regardless of race/ethnicity. Moreover, 28 % agree that medical researchers act differently toward minorities. Between 9 and 11% believe that researchers select minorities for their most dangerous studies and some projects are secretly designed to expose minoritized groups to diseases. Our next step is to disaggregate the data by race and ethnicity and evaluate these answers. DISCUSSION/SIGNIFICANCE: This study's population willingly engaged in a research registry making their diminished trust quite alarming. Amongst the general population, trust in scientists is now below pre-pandemic levels. We must critically assess our own trustworthiness, and critically reflect on the authenticity of our efforts.

OBJECTIVES/SPECIFIC AIMS: More than 2 out of 3 adults in the United States are overweight or obese. Obesity disproportionately affects minority populations. There is limited data on obesity and CVD risks among inner-city minority cab drivers in New York City (NYC). The goal is to study perceptions, knowledge and health behaviors of Hispanic livery cab drivers of NYC that contributes to obesity. METHODS/STUDY POPULATION: We conducted an observational study of focus groups related to perception, knowledge, or behavior among Latino livery cab drivers of NYC. Direct transcription of the taped recordings into concepts were grouped into themes and common themes were categorized. The sample size of the focus groups was based on the saturation point where common themes emerged. RESULTS/ANTICIPATED RESULTS: In total, 25 Latino livery cab drivers were enrolled. Of those, 24 were men. Mean age is 53 years (21–69); body mass index (BMI) is 31 (22.8–38.7) kg/m2; 50% had hypertension and 27% had diabetes. Eight dominant themes emerged. Cab drivers were aware of their increased risk for CVD which most of them attributed to work stress, sedentary lifestyle, and poor eating habits “on-the-go”. In particular, they mentioned a tendency of having “Pipa,” a Spanish term denoting increased abdominal girth, which they equated to early death. Family and social support was an important facilitator in changing unhealthy behaviors. DISCUSSION/SIGNIFICANCE OF IMPACT: Our study shows that minority cab drivers are generally obese or overweight and aware of their personal risk factors for CVD including central obesity. Social and family support may be key to improving their lifestyle. An evidenced-based health model that includes family education and decision support will be tested in our next study phase to understand if it can improve body weight.

OBJECTIVES/GOALS: To evaluate whether a low cost, functional dynamic 3-D printed upper extremity (UE) orthosis could be designed, fabricated and used by children with cerebral palsy (CP) with severe unilateral UE involvement and the ability of common standardized instruments to assess its effectiveness. METHODS/STUDY POPULATION: Five patients, ages 13-17 years, with CP and unilateral UE involvement, MACS levels III-IV, were enrolled. Custom forearm thumb opponens orthosis and dynamic upper extremity orthosis (DUEO) were designed and fabricated by a multidisciplinary team for use during 8 one-hour occupational therapy sessions targeting bimanual UE training. Pre- and post-assessments included Assisting Hand Assessment(AHA), Melbourne-2(MA-2), Pediatric Motor Activity Log-Revised(PMAL-R), and PedsQL Measurement Model for the Pediatric Quality of Life Inventory: CP Module(Peds-QL). RESULTS/ANTICIPATED RESULTS: The 3D printed orthotic device is custom fit to the patient based on scans of their arm and is designed with a tensioning system that allows for functional usage of the arm. It incorporates a rigid polymer to provide support and flexible material for comfort where appropriate. Overall, higher post-treatment scores were found for the majority of participants using the custom orthotic. Four made minimal clinically important differences (MCID) in the AHA. Three met MCID scores in subtests of MA-2 (two positive and one negative). Patient-reported outcome improvements were found for PMAL-R for four, but only one met MCID and at least three reported improvements in more than one domain of PedsQL. DISCUSSION/SIGNIFICANCE: Children with CP may often present with UE impairment, yet current therapeutic orthoses only target the progression of contractures and are still limited by cost and discomfort. Our team designed and fabricated a functional, low cost, 3D printed orthosis that showed significant gains in UE function.
