370 Developing a Digitally Integrated Endotracheal Tube for Neonates to Improve Safety and Respiratory Function
Authors: Nienaber Thomas , Perez Sarah , Stephenson Krista , Sanford Joseph , Abella Adria , Jensen Morten , Sexton Kevin
Published: April 2022

OBJECTIVES/GOALS: Neonatal endotracheal tubes (ETTs) are usually uncuffed to avoid subglottic stenosis and other complications, but cuffed ETTs allow better ventilation. Our goal was to detect and control pressure in the cuff below the limit of occluding venous flow to minimize the risk of subglottic stenosis. METHODS/STUDY POPULATION: We designed a pressure sensor to fit on a 2.5 ETT for prototype testing in 8 age adult female rabbits. Eight uncuffed age- and sex- matched rabbits served as control. Study duration was 2 hours during which pressure in the cuff was limited by novel sensor (intervention) or auscultation (control). Anesthesia was maintained with sevoflurane. Ventilation was provided mechanically. Subsequently the tracheae were removed, sectioned crosswise, and compared histologically for mucosal damage. RESULTS/ANTICIPATED RESULTS: Preliminary data demonstrated an almost 30% greater amount of intact mucosa in the intervention group. The sensor also provided data on heart rate and respiratory rate, although this signal was not optimal. After filing an invention disclosure and provisional patent, we are refining our device to include multiple compartments for local control of cuff pressure and applying for a STTR Phase I/II application. DISCUSSION/SIGNIFICANCE: Ventilation in neonates with uncuffed ETTs can be suboptimal due to leak around the tube, but cuffed ETTs pose the threat of subglottic stenosis and other complications. We have designed a prototype cuffed ETT with a sensor to maintain low cuff pressure while preventing leaks and largely avoiding damage to the tracheal mucosa.
376 The Role of Antiretroviral Treatment Patenting on Consumer Pricing: Declining Viral Suppression and Treatment Non-Adherence Among HIV Patients in Los Angeles County
Authors: Crovetto Arianna
Published: April 2022

OBJECTIVES/GOALS: Antiretroviral treatments (ART) suppress retroviruses, like the human immunodeficiency virus (HIV). The goal is to understand how antiretroviral drug patents contribute to overpriced HIV medications, thereby causing cost-related treatment non-adherence and inhibiting viral suppression. METHODS/STUDY POPULATION: Currently, HIV affects 57,700 individuals in Los Angeles County (LAC). Data was compiled from Centers for Disease Control and Prevention (CDC), hiv.gov, lacounty.HIV, publichealth.lacounty.gov, and the U.S. Patent and Trade Office. A review of existing literature examined the role of ART patents on cost-related non-adherence and declining viral suppression on individuals living with HIV in LAC. Lastly, a comparison of HIV medication prices of expired and non-expired patents was conducted, indicating the effects of undue extensions of market exclusivity on ART regimen pricing, and how this affects treatment adherence. RESULTS/ANTICIPATED RESULTS: Of the ten ARTs examined, four had expired patents and six had active patents. Those with active patents cost more than those with inactive patents because active patent status prevents price reductions. Patent strategies–pay-for-delay settlements and patent evergreening–unduly extend market exclusivity, keeping ART at prohibitive costs and preventing generic competition. Individuals facing cost-related non-adherence were less virally suppressed at their last viral load test (64%) and at all tests during the year (54%). Thus, over-patented ARTs increase treatment prices, causing cost-related non-adherence to ART regimens. The implications include disease progression and less viral suppression. DISCUSSION/SIGNIFICANCE: The U.S. has the highest ART prices, yet the lowest rate of HIV viral suppression (54%) among all well-resourced countries. Undue extensions of market exclusivity cause ARTs to remain at prohibitive costs, preventing some patients from affording ART treatments, minimizing their viral suppression.

Authors: Cuddihy Meghan J , Cook Samantha , Martin Bradley J. , Vemuri Chandu , Ghanbari Hamid , Eagle Kim A. , Servoss Jonathan M.
Published: April 2022

OBJECTIVES/GOALS: The University of Michigan Frankel Cardiovascular Center (FCVC) Innovation Challenge is an annual competition offering funding for innovative ideas to improve cardiovascular care. Due to the COVID-19 pandemic, administrators converted the recruitment process and pitch event to fully virtual. METHODS/STUDY POPULATION: We detail the process of converting the event from a hybrid process (virtual and in-person recruiting and in-person event) to a fully virtual one. Changes to the event included implementing a virtual recruiting process utilizing short video recordings as submission format; a new tool for storing and displaying submissions; fully virtual finalist selection and coaching; and a fully virtual pitch and judging event. The submission process tracked information about submissions that include the type of idea (process or product), role of team lead, and department of team lead. RESULTS/ANTICIPATED RESULTS: The FCVC Innovation Challenge was successfully converted to a fully virtual event. Methods and tools will be shared to allow similar institutions to replicate a successful virtual pitch event. These include methods and tools utilized to allow participants to describe their ideas, strategies to select and coach finalists, and to host a virtual pitch event. Data will be shared on the number of ideas and category (product/process) of projects submitted, and number and category of finalists selected. DISCUSSION/SIGNIFICANCE: This case review can demonstrate how institutions can use a similar virtual idea submission and pitch process to (1) catalyze innovative ideas that can impact patient care by accessing its communitys ideas and (2) fund innovative ideas that do not fit traditional mechanisms.
387 Clinical characteristics and psychosocial factors associated with temporary neuromodulation success
Authors: Stephens Kimberly E , Dooley Mary Frances , Byers Lauren A , Goree Johnathan H.
Published: April 2022

OBJECTIVES/GOALS: The present work aims to use baseline data to identify demographic, clinical, and psychosocial factors associated with patients who receive analgesic benefit from temporary neurostimulation. METHODS/STUDY POPULATION: This study presents baseline data from our descriptive, prospective, longitudinal study. Consecutive patients who present to the University of Arkansas for Medical Sciences Interventional Pain Management Clinic for implantation of a neurostimulation device, have met clinical criteria for implantation of a neuromodulation device, and are able to speak and understand English are invited to participate. Prior to the placement of the temporary stimulator, each patient completes demographic and symptom-related questionnaires. Clinical characteristics are obtained through medical record review. RESULTS/ANTICIPATED RESULTS: We anticipate enrolling 50 participants in order to have 30 patients that report analgesic benefit from temporary neurostimulation. Variability in demographics, clinical characteristics, and psychosocial factors will be reported between patients who receive and those who do not receive analgesia following temporary neurostimulation. Gender differences will also be reported. DISCUSSION/SIGNIFICANCE: Despite the use of varying outcome measures, studies to date have not incorporated validated patient reported outcomes or controlled for key demographic and clinical characteristics. Our analysis evaluates clinical and psychosocial variables associated with successful temporary neurostimulation.
397 Factors needing attention to implement effective drug treatment in community correctional in Puerto Rico
Authors: Vega Debien Graciela D. , Santos Angellyn , Ortega Jesús , Albizu Carmen E.
Published: April 2022

OBJECTIVES/GOALS: The complex health profile of those supervised by community corrections places them at a greater risk of morbidity and mortality from social disruption, infection, and of substance misuse, relapse, and overdose. This study aims to explore individual and social determinants of SUD and treatment utilization for this population. METHODS/STUDY POPULATION: A secondary data analysis was conducted using an administrative database from the Department of Corrections of Puerto Rico (DoC-PR) that included individuals under community supervision between 2015 and 2018 (N=13,163). Two logistic regression analysis were performed to predict SUD and SUD treatment utilization. The predictors included in the models were: a) age, b) gender, c) civil status, d) education level, e) employment status, f) income, g) number of dependents, h) housing zone, I) type of crime, j) offender classification k) community sentence classification, and k) sentence duration. RESULTS/ANTICIPATED RESULTS: A total of 4,531 cases (34.4%) were identified with an SUD and of these 79.2% were enrolled in treatment. Significant predictors of SUD included a parole sentence (vs probation), commission of felony, decreasing sentence duration and recidivism. Significant demographic variables include, male, single, younger age, unemployed, residing in an urban zone and decreasing income. Significant predictors for SUD treatment utilization were a probation sentence, older age and residing in a rural zone. Mandated treatment may explain a higher likelihood of treatment utilization, yet prevalent modalities consist of residential abstinence based, non-professionalized services known to have poor treatment outcomes. The current data set does not include follow up data to assess changes in treatment utilization. DISCUSSION/SIGNIFICANCE: We should aim to prevent health and social disparities and risk of sentence revocation associated with interventions that lack evidence to support their effectiveness. Next steps should address challenges and opportunities for the adoption of EBPPs for individuals with an SUD under community corrections supervision.
399 Advanced Practice Provider Perspectives on Advanced Care Planning
Authors: Johnson Christopher , Colley Alexis , Broering Jeanette , Bongiovanni Tasce , Roman Sanziana , Wick Elizabeth
Published: April 2022

OBJECTIVES/GOALS: Perioperative surgical care is team-based with close partnership between surgeons, residents, advanced practice professionals (APPs), and others. The objective is to develop an understanding of the current state and implementation needs required for APPs to engage surgical patients in advanced care planning (ACP) to promote goal concordant care. METHODS/STUDY POPULATION: We will conduct a mixed methods evaluation of ACP knowledge, attitudes, and beliefs amongst surgical APPs to identify barriers and facilitators of APPs engaging in a team-based approach to engaging surgical patients in ACP. We will conduct an online survey and qualitative interviews in the following 4 domains: 1) knowledge, skills, and attitudes about engaging in ACP with a patient or their surrogate decision maker during their perioperative care; 2) prior ACP-specific education; 3) experiences conducting ACP discussions with patients; and 4) perceived training needs to increase ACP uptake and documentation. The findings will provide the foundations to design team-based interventions focused on addressing the barriers and inform training and coaching needs to develop expertise and comfort in the ACP process. RESULTS/ANTICIPATED RESULTS: We expect variability in the knowledge, skills, attitudes, and experiences with the ACP process. We anticipate gaining a better understanding of the educational materials best suited to support APPs as they begin engaging patients in ACP. Possible barriers to APP-led ACP discussions include inconsistent role delineation, uncertainty about the value of pre-operative vs. post-operative ACP discussions, lack of experience engaging in ACP discussion, and lack of familiarity with electronic health records ACP tools. Possible facilitators of APP-led ACP discussions may be related to past work experience settings, exposure to ACP in educational preparation, hands-on observation of value of ACP in surgical patients and influences from attending and residents. DISCUSSION/SIGNIFICANCE: While current ACP research in surgery focuses on physician-led patient engagement in ACP discussions, there is a paucity of research focusing on how to develop a team-based approach to ACP discussions in surgery. This study will provide information necessary for the development of interventions that increase team-based ACP for surgical patients.
402 Quantifying Heavy Metals in Interstitial Fluid for Remote Monitoring of Chronic Exposures
Authors: Taylor Robert , Zhu Yiliang , Bolt Alicia
Published: April 2022

OBJECTIVES/GOALS: Our hypothesis is that microneedle array (MA) extraction of interstitial fluid (ISF) will enable minimally invasive quantitation of heavy metal (HM) exposure. We aim to establish analytical parameters for ICP-MS analysis of HMs, quantify baseline HM content in ISF vs other fluids, and characterize a mixed HM exposure model. METHODS/STUDY POPULATION: Ten healthy human volunteers were recruited into the study, approved by the UNM Human Research and Resource Committee Each subject had blood and urine collected. ISF was also collected using 3D-printed MAs inserted into the forearm. Additionally, twelve Sprague Dawley rats were unexposed (n=6) or exposed (n=6) to ad libitum water containing a mixture of uranium (U), cadmium (Cd), vanadium (V), and arsenic (As), each at 5X the maximum contaminant level (MCL) for drinking water under a protocol approved by the UNM animal care and use program. Human and animal fluids were analyzed, using ICP-MS, to quantify the levels of U, Cd, V, and As. RESULTS/ANTICIPATED RESULTS: Recent advances in ISF extraction and analysis suggest a minimally invasive method that can be adapted to monitor HM exposure and biological loads longitudinally in both localized and dispersed communities. ISF can be collected with MAs and is a rich source of disease and exposure biomarkers. However, determining biological loads remains challenging due to the need to collect blood or urine from a dispersed rural population over time. Our preliminary results suggest similar HM concentrations in ISF, compared with blood in small unexposed human and animal populations. All four metals can be successfully quantified in tandem using ICP-MS. DISCUSSION/SIGNIFICANCE: Chronic exposure to heavy metals (HM) is associated with detrimental health effects. Exposure to multiple HMs is suspected to have additive or synergistic harmful effects. We envision a wearable microneedle patch that could be mailed to individuals or distributed through community centers, worn for a few hours, and returned to a central laboratory.
404 Gaps in Physical Therapists’ and Physical Therapist Assistants Knowledge and Use of the CDC’s STEADI for Falls Risk Screening of Older Adults in the United States
Authors: Vincenzo Jennifer L. , Schrodt Lori A. , Hergott Colleen , Perera Subashan , Tripken Jennifer , Shubert Tiffany E. , Brach Jennifer S.
Published: April 2022

OBJECTIVES/GOALS: Studies using Medicare data indicate that physical therapists (PTs) and physical therapist assistants (PTAs) are not providing falls prevention to at-risk older adults in rehabilitation. We aimed to identify PTs and PTAs knowledge and use of the Centers for Disease Control and Prevention’s STEADI fall prevention toolkit. METHODS/STUDY POPULATION: We conducted a cross-sectional survey distributed to a convenience sample of PTs and PTAs in the United States through email blasts and social media. Descriptive statistics were used to summarize the demographic characteristics of the respondents. Some categorical variables were combined to provide more meaningful classifications or due to small frequencies. We used independent samples t-tests for continuous data, and chi-square and Fisher’s Exact tests for categorical data to compare characteristics between respondents that do and do not conduct falls risk screenings.Frequency counts and percentages were used to summarize survey responses related to falls risk screening and knowledge/use of STEADI. SASÂ® version 9.4 was used for all statistical analyses. RESULTS/ANTICIPATED RESULTS: PTs and PTAs (N = 425) who responded to the survey and worked in clinical settings with older adults were included. Eighty-nine percent of respondents reported conducting clinical falls risk screening, yet only 51% were 'familiar’ to 'very familiar’ with STEADI. Twenty-two percent of respondents were not familiar at all with STEADI. Of the respondents who were 'very familiar with the STEADI (n = 132, 31.1%), 84.1% (n = 111) reported using STEADI in clinical practice. Seventy-six percent of respondents who use the STEADI implemented it by choice even though the majority (52.1%, n = 63) did not have it embedded in their workflow or documentation. DISCUSSION/SIGNIFICANCE: PTs and PTAs in the United States have some familiarity with and use STEADI in clinical falls prevention, and those who are very familiar with it use it by choice. Further research is needed to address the knowledge gap of STEADI and support PTs and PTAs providing falls prevention to older adults attending rehabilitation.
407 Glucose activates STAT3, promoting XRCC1 expression and increased DNA repair after exogenous challenge
Authors: Gassman Natalie R , Wright Griffin M , Gassman Natalie R
Published: April 2022

OBJECTIVES/GOALS: Inflammation-promoting exposures, including hyperglycemia and inflammatory cytokines, are common in the development and progression of multiple cancers. Here, we determine if high glucose drives the dysregulation of XRCC1, changing BER/SSBR capacity, and increasing resistance to DNA damaging agents. METHODS/STUDY POPULATION: Here, we acutely exposed cell lines models with 30 mM glucose to mimic hyperglycemic changes and monitored the gene and protein expression of STAT3 and XRCC1. We selected the osteosarcoma cell line U2OS, with high STAT3 activation before glucose challenge, and the non-tumorigenic human embryonic kidney cell line HEK293T, with low STAT3 activation before glucose challenge, to dissect the role STAT3 plays in dysregulating DNA repair. We also examined changes in STAT3 occupancy at the XRCC1 promoter following glucose challenge using chromatin immunoprecipitation (ChIP). Finally, we measured changes in the sensitivity to the alkylating agent methyl methanesulfonate (MMS) induced by the glucose challenge using cell survival and DNA strand break analysis. RESULTS/ANTICIPATED RESULTS: High glucose challenge increases the phosphorylation and activation of STAT3 and subsequently increases XRCC1 gene and protein content in the cell. Acute high glucose activated STAT3, driving the subsequent expression of XRCC1 in U2OS and HEK293T cells through increased STAT3 occupancy at the XRCC1 promoter. High glucose also reduced sensitivity to MMS, increasing cell survival. The most significant increase in resistance to MMS occurred in the HEK293T, which also showed the largest increase in XRCC1 protein expression following the glucose challenge. Increased survival correlated with the faster resolution of DNA strand breaks in glucose-challenged cell lines. DISCUSSION/SIGNIFICANCE: This work has identified a novel regulatory mechanism by which high glucose drives the expression of XRCC1 through STAT3 activation, increasing DNA repair and resistance to the DNA damaging agent MMS. These data suggest dietary choices induce sustained XRCC1 expression and may contribute to chemoresistance and poor survival outcomes in cancers.
409 Diffusion MRI to investigate atypical corticospinal tract microstructure and motor impairments in hemiplegic cerebral palsy
Authors: Hruby Alexandra , Joshi Divya , Dewald Julius PA , Ingo Carson
Published: April 2022

OBJECTIVES/GOALS: Hemiplegic cerebral palsy (HCP) limits the functional ability of one side of the body, but motor impairments are very heterogeneous among children with this diagnosis. The purpose of this study was to evaluate the CST using DTI and tractography analyses as it relates to quantitative measures of the severity of weakness and mirror movements in HCP. METHODS/STUDY POPULATION: Preliminary results include five participants with HCP (2M, 16Â±7.8 years) and six controls (2M, 12Â±3.5 years). DTI data were collected using a spin-echo echo-planar imaging sequence with diffusion weighting of b=1000 s/mm2 in 60 different directions and 8 scans without diffusion weighting (b=0 s/mm2). Images were processed with steps of brain extraction, denoising, motion and eddy current correction, and fit with tensors to generate maps of diffusivity metrics. Anatomical landmarks were used to guide probabilistic tractography of the CST for analyses in both the lesioned and non-lesioned hemispheres. To quantify grasp weakness and mirroring severity, participants completed a bilateral assessment of grip strength using handheld force measurement devices and custom MATLAB data acquisition software. RESULTS/ANTICIPATED RESULTS: DTI is a feasible method to evaluate CST microstructure in HCP and typically developing pediatric participants. Spearman correlation analyses, using age and sex as covariates, revealed that for the lesioned hemisphere CST, there were significant positive correlations between grasp weakness severity and mean diffusivity (MD) (Ï=0.66, p=0.038) and between grasp weakness severity and axial diffusivity (AD) (Ï =0.68, p=0.030). There was not a significant correlation between grasp weakness severity and fractional anisotropy (FA) (Ï =-0.47, p=0.166). For the non-lesioned hemisphere CST, there was a significant positive correlation between mirroring severity and radial diffusivity (RD) (Ï =0.70, p=0.023). There was not a significant correlation between mirror movement severity and FA (Ï =-0.41, p=0.2361). DISCUSSION/SIGNIFICANCE: The correlations demonstrated here show a potential relationship between CST microstructure and the severity of hand impairments in HCP. While these relationships between CST diffusivity properties and hand function are preliminary, they provide the first steps to better understand underlying neural mechanisms for motor impairments in HCP.
414 Behaviors and Quality of Life in Children with Neurodevelopmental Disorders Undergoing Refractive Surgery
Authors: Zdonczyk Alexandra , Tychsen Lawrence , Reynolds Margaret
Published: April 2022

OBJECTIVES/GOALS: The goal of this project is to characterize the adaptive and social behaviors of ametropic children with neurodevelopmental disorders (NDD) including Autism Spectrum Disorder (ASD) undergoing refractive surgery due to spectacle intolerance. Eye-related quality of life and visual behaviors will also be measured. METHODS/STUDY POPULATION: This is an ongoing prospective cohort study of children with NDD who are spectacle-intolerant and undergoing refractive surgery at St. Louis Childrens Hospital starting July 2020. The method of refractive surgery (photorefractive keratectomy (PRK), phakic intraocular lens implantation (phIOL), and refractive lens exchange (RLx)) is chosen based on degree and type of refractive error, astigmatism, and characteristics of the cornea and anterior chamber. Behaviors are characterized using the Adaptive Behavioral Assessment System, 3rd edition (ABAS-3) and Social Responsiveness Scale, 2nd edition (SRS-2), completed by parents/caregivers. Eye-related quality of life is measured using the pediatric Eye Questionnaire (PedEyeQ). Visual behaviors are assessed with optokinetic nystagmus tracking. RESULTS/ANTICIPATED RESULTS: In a preliminary sample of 9 patients, 4 have undergone PRK, 3 phIOL, and 2 are awaiting surgery. Pre-surgical SRS-2 scores had a median t-score of 70 (range 57 to 90), indicating a clinically significant deficiency in reciprocal social behaviors as this score is consistent with moderately severe ASD. Pre-surgical ABAS-3 scores had a median General Adaptive Composite (GAC) of 51 (range 48 to 74.5). This corresponds to a percentile of 0.100 (range <0.1 to 19th percentile for age). As rated by the Parental PedEyeQ, the domains most affected were “Parent Worry About Childs Eye Condition” (median 42.0, range 15.0 to 80.0) and “Parent Worry About Functional Vision” (median 18.8, range 3.2 to 68.7), where 0 represents the worst quality of life or functional vision and 100 the best. DISCUSSION/SIGNIFICANCE: Prior research has shown that refractive surgery can improve observed visual awareness, attentiveness, or social interactions in children with NDD. This is the first study to characterize the baseline adaptive/social behaviors and quality of life using validated surveys, with the goal of subsequently identifying patients most likely to benefit.
442 Repurposing FDA-approved PI3K/Akt Inhibitors to Improve Anti-Cancer Drug Brain Uptake in Glioblastoma Resection Models
Authors: Rodgers Louis , Tega Yuma , Schulz Julia A. , Hartz Anika M.S. , Bauer Bjoern
Published: April 2022

OBJECTIVES/GOALS: We have shown that glioblastoma upregulates blood-brain barrier drug efflux transporters via a mechanism that likely involves TNFÎ± and PI3K/Akt. Our goal is to repurpose FDA-approved PI3K/Akt inhibitors to increase anticancer drug brain concentrations, which holds the potential for translation into the neuro-oncology clinic. METHODS/STUDY POPULATION: GL261 Red-FLuc and MBR525-1 Red-FLuc cells (2Î¼l; 2.5K cells/Î¼l; 1Î¼l/min) were injected into the right hemisphere of 8-week old female J:NU mice (coordinates relative to bregma: AP -2 mm, ML -2 mm, DV -3 mm). Tumor burden was assessed weekly with IVISÂ® Spectrum in vivo imaging; tumor volume and invasiveness were measured by MRI and histopathology, respectively. On day 14 post-injection, mice received 5-ALA (200 mg/kg ip), and tumors were resected with a 2 mm punch biopsy tool and surgical fluorescence microscope (ex/em: 405/635nm). Drug efflux transporter expression and activity in isolated brain capillaries were determined by Western blot and substrate fluorescence assays, respectively. Cytotoxicity was assessed after 48-hour drug incubation using CyQuant MTT Cell Proliferation Assay kits. RESULTS/ANTICIPATED RESULTS: IC50 values of temozolomide, lapatinib, alpelisib, and miltefosine were N/A, 32, 20, and 190 Î¼M for GL261 Red-FLuc cells and N/A, 49, 36, and 148 Î¼M for MBR525-1 Red-FLuc cells, respectively. Median survival of GL261 Red-FLuc mice was 26.5d and significantly increased to 34d with resection (p=0.116). In GBM mice, drug efflux transporter expression and activity levels in brain capillaries isolated from the contralateral hemisphere were significantly upregulated compared to sham controls. Furthermore, treatment with FDA-approved PI3K/Akt inhibitors, alpelisib and miltefosine, significantly reduced drug efflux transporter expression and activity to control levels. In PK and survival studies, we expect that PI3K/Akt inhibition will increase brain uptake of anticancer drugs and prolong GBM mouse survival. DISCUSSION/SIGNIFICANCE: We have previously shown that PI3K/Akt inhibition reduces P-gp/BCRP levels in brain capillaries. Here, we vertically extend this strategy by repurposing the FDA-approved PI3K/Akt inhibitors alpelisib/miltefosine to improve brain uptake of anticancer drugs in GBM resection models.
106 Cumulative Cancer Location Incidence and Cancer Progression in an Active Surveillance Cohort
Authors: Holler Albert E , De La Cale Claire , Mamawala Mufaddal , Pavlovich Christian
Published: April 2022

OBJECTIVES/GOALS: Prostate cancer is the 2nd most common cancer among men. 1/3 of these men have a slow-growing disease that can be managed without intervention. Instead of treatment, they can enter an active surveillance program. The goal of this study is to examine if cumulative cancer location can predict one’s disease progression and be used as a clinical marker. METHODS/STUDY POPULATION: This is a retrospective cohort study consisting of men with Gleason Grade 1 prostate cancer enrolled in the Active Surveillance Program at Johns Hopkins. The cohort includes men who were enrolled in the program from 2007 to 2015 before prostate biopsies incorporated multiparametric MRI as of the prostate. We will assess if cumulative cancer location (CCLO), a sum of the total number of histological cancer-positive locations on diagnostic and confirmatory biopsy, can predict grade progression, adverse findings on radical prostatectomy findings, or protocol-based discontinuation. Kaplan Meier survival analyses and multivariable Cox regression will be used to determine if stratifying by CCLO can predict these outcomes. RESULTS/ANTICIPATED RESULTS: We included 1298 men in this study. The study will analyze variables that will be used in multivariable regression. Some variables of interest include age at diagnosis, PSA, PSA density, race/ethnicity, and number of positive cores. We expect that greater variability of tumor location, a higher CCLO score, will lead to more grade progression, protocol-based discontinuation, shorter time on active surveillance and adverse findings after radical prostatectomy. This hypothesis is based on a 2018 study that determined cancer location as a significant predictor of progression at the time of biopsy. Results will be discussed in full at the conference. DISCUSSION/SIGNIFICANCE: Finding a predictive marker of progression at the time of biopsy is clinically significant and can lead to adjusted patient observation and testing while on active surveillance. This will better stratify men on active surveillance, determine who would benefit from genetic testing, and better counsel patients as to how long they will be on surveillance.
476 Training basic researchers in translational approaches to facilitate the application of laboratory discoveries
Authors: Dillon Pamela , Lloyd Joyce , Sarkar Devanand
Published: April 2022

OBJECTIVES/GOALS: To maximize health outcomes from their work, basic researchers must understand the process by which lab discoveries are translated into clinical care. We developed an academic course designed to provide students in our Clinical and Translational Sciences PhD program with an in-depth understanding of translational applications of basic research. METHODS/STUDY POPULATION: A preliminary needs assessment was done with students, educators, and clinicians to identify the course content. Based on these data, didactic modules including research question identification, research team development, participant recruitment, and research data collection were piloted in a synchronous, virtual course. Then, for 6 weeks, students shadowed clinical mentors who worked in the students research areas. Finally, with their mentors, students developed and presented clinical research protocols. Student pre- and post-course surveys gauged alignment of course objectives and learning outcomes. A post-course, focus group with students gathered feedback on course content, structure, and students confidence in implementing their experiences from the course into real-world settings. RESULTS/ANTICIPATED RESULTS: Six MD/PhD and PhD students participated in the pilot course. Pre/post-assessments (n=4) showed students were more confident in clinical question/research protocol formulation, development of patient recruitment/enrollment strategies, and integration of research methodologies into their research projects after completing the course. Students asked for additional content on budgeting and grant funding. Post-course focus group participants (n=2) appreciated the experience of writing a clinical protocol and the flipped classroom teaching style, which allowed them to network with clinical faculty leading didactic sessions. Students also noted course content was relevant and motivating, although they suggested adding content about clinical trials measures to enhance their shadowing experiences. DISCUSSION/SIGNIFICANCE: A course that combines didactic and clinical experiential training provides a robust, translational research foundation for basic scientists. This training is critical to help them contribute to the effective/efficient translation of lab discoveries to clinical practice. Future course development will include students from other PhD programs.
477 The Climate is Changing, Why Cant We? Faculty Perspectives on Education for Sustainable Healthcare in Health Education
Authors: Hampshire Karly , Nicastro Tammy , Teherani Arianne , Weiser Sheri
Published: April 2022

OBJECTIVES/GOALS: Despite calls for the integration of Education for Sustainable Healthcare (ESH) into health professional training programs, most curricula have yet to adapt accordingly. This qualitative study sought to understand faculty perspectives on ESH knowledge, interest, barriers, and facilitators. METHODS/STUDY POPULATION: From 2018 to 2020, 71 health professional education faculty from 6 University of California (UC) campuses participated in ESH integration workshops. Using purposeful sampling based on gender and campus, a subset of workshop faculty participants were selected to participate in individual interviews. Interviews were conducted via Zoom using a structured interview guide, eliciting participants experience integrating ESH, perceived barriers and facilitators, and perspectives on student, faculty, and health science leadership knowledge and interest. Transcripts were double coded with an inductive-deductive approach using Dedoose, reconciled, and analyzed to identify themes. RESULTS/ANTICIPATED RESULTS: Participants included 17 faculty at 6 UC campuses representing diverse health disciplines. Although participants noted high general awareness of and interest in climate change among students and faculty, they observed a lack of specific, health-relevant knowledge, resulting in discomfort communicating with others on climate and health. Perceived barriers to expansion of ESH included limited curricular space, competing topics, and lack of faculty expertise. Participants posited that framing climate change in health terms, establishing learning objectives and protected faculty time, identifying connections to ESH within existing research and curriculum, and obtaining commitments from campus leadership would facilitate successful ESH integration. DISCUSSION/SIGNIFICANCE: Our findings reinforce student and faculty interest in ESH curricular integration and identify important barriers and facilitators, lending context for educators planning ESH infusion. Training of faculty on climate health is urgently needed for ESH integration in health professional education.
483 Research 101: Building the Research Skills of Practicing Clinicians
Authors: Dawson Amy P. , Callahan Kathryn E. , Perry Anna , Olivier Claudia , Munn Lindsay T.
Published: April 2022

OBJECTIVES/GOALS: The goal was to develop foundational research knowledge and skills for clinicians interested in conducting clinical research. Emphasis was on the development of a research question and the iterative process necessary to transform a research question into a well-designed study and well-articulated research proposal for pilot grant funding. METHODS/STUDY POPULATION: The course took place over 10 sessions, May - September 2021. The application process required participants to provide an initial self-assessment of research skills and a proposed research question. 25 clinicians applied to the program, 11 were accepted, and 9 enrolled. All clinicians in the initial cohort were clinical faculty physicians. Because of the geographical distance of participants as well as the ongoing pandemic, the course used a blended learning approach with both synchronous and asynchronous learning. Participants viewed online lectures on core content coupled with live virtual sessions with opportunities for discussion and application of the content. Relevant CTSI and institutional resources were highlighted in each session. RESULTS/ANTICIPATED RESULTS: Of the 9 clinician participants who enrolled in Research 101, the average attendance per session was 67% or 6 people. 89% or 8 participants attended five or more sessions. 5 participants submitted a letter of intent for the annual CTSI Pilot grant program, and of the five, two were invited to submit a grant application. Formal evaluation of the program is currently ongoing and will close on November 30th, at which time full results will be available. Research competencies will be assessed through a pre-post comparison, each self-rated by course participants. Additionally, participants were asked to provide input on the most and least valuable components of the course, as well as any open-ended feedback. Research 101 leadership will use these results to improve the course for future participants. DISCUSSION/SIGNIFICANCE: A learning health system (LHS) is recognized as an essential means by which research evidence is translated into practice. Important to realizing the LHS vision is the engagement of clinicians into the generation and translation of research into practice. Research 101 is an important way to bolster clinician engagement in translational research.

Authors: Patel Anuj , Hoskeri Rishi , Reighard Chelsea , Zopf David
Published: April 2022

OBJECTIVES/GOALS: Many ophthalmologic procedures involve operating on or manipulating the globe and bony orbit. Creating an anatomically accurate globe and orbit is of interest to improve surgical education for trainees. The purpose of this study was to create a high-fidelity globe and orbit model using synthetic materials and utilizing 3D-printing techniques. METHODS/STUDY POPULATION: A deidentified computed tomography scan of the head and neck was digitally rendered and segmented using Mimics and 3-Matic (Materialise NV, Belgium) to create a digital model of the bony orbit. The model was 3D printed using a stereolithographic 3D-printer (Formlabs, Somerville, MA). The globe was created by soaking a large water bead made from a water absorbing polymer (YIQUDUO, China) for 24 hours. The water bead was then coated consecutively with three layers of silicone (Smooth-On, Macungie, PA). A standard sausage casing was hydrated and encased around the water bead, representing the conjunctiva. The globe was placed into the 3D-printed orbit. An incision was made in the sausage casing and the defect was sutured by one ophthalmologist. RESULTS/ANTICIPATED RESULTS: The bony orbital anatomy was accurately represented by stereolithographic printing. The size and feel of the artificial globe was similar to that of an in vivo human globe. The incised sausage casing covering the globe was able to be manipulated and sutured using a 8-0 suture in a microsurgical environment. The sausage casing had high-fidelity characteristics of an in vivo human eye conjunctiva. DISCUSSION/SIGNIFICANCE: This model can be used for teaching of conjunctival suturing for ophthalmologic trainees. By use of easily obtained materials for the globe, this model has the potential to standardize teaching methods of challenging techniques, and can reduce the need for animal and human tissue procurement, which is the current standard for ophthalmologic teaching.

Published: April 2022

OBJECTIVES/GOALS: The objective of this evaluation is to evaluate the long-term impact of the PORT program on the clinical and translational research careers of the participating research staff. The impact of the program is best demonstrated through measures of the scientific contributions of the participants as well as their professional advancement over time. METHODS/STUDY POPULATION: The PORT program participants were tracked through the collection of instructional and public records, including the collection of their subsequent grant and publications. The clinical and translational research careers of the participants was also assessed, using a measure adapted from the operational guidelines for NCATS’ Research Careers Common Metric. A survey was administered to part participants and interviews conducted with participants from the past cohorts. RESULTS/ANTICIPATED RESULTS: The evaluation results demonstrate the PORT program participants made substantial contributions to the advancement of clinical and translational research, particularly through their publication of hundreds of scientific works. In addition, the evaluation results reveal that the program had short-, intermediate- and long-term impact on their research careers, thereby contributing to the advancement of the health research workforce at the University of Michigan for well over a decade. Specific participant cases highlight how individuals utilized their experience and training to advance research agendas and their long-term careers at the institution. These findings can inform the development, implementation and evaluation of similar programs throughout the CTSA consortium and beyond. DISCUSSION/SIGNIFICANCE: Most evaluations of research training and award programs for clinical and translational research staff do not evaluate the long-term impact of CTSA support on the research careers of the participants. The findings of this evaluation can help inform the development of new and more effective workforce development initiatives with long-term impact.

OBJECTIVES/GOALS: The goal of this study is to describe the implementation of a formal research mentoring training program at Miami CTSI in collaboration with University of Colorado CTSI, to build effective mentor-mentee relationships that help build successful research careers for junior faculty. METHODS/STUDY POPULATION: The Miami CTSI Research Mentoring Training is a three-part series for early stage faculty and their mentors to strengthen mentoring skills and build successful relationships. The curriculum uses evidence-based strategies and is modeled after University of Colorado CTSIs CO-Mentor Training Program. The pilot training was conducted as a train-the-trainer program with subsequent workshops led by Miami CTSI faculty. The program has mentee-only, mentor-only, and joint sessions covering topics such as networking skills, managing financial aspects of an academic career, and career mapping. To assess program effectiveness, pre/post surveys were conducted and follow up surveys are planned. Data collected will assess participant diversity, research productivity, and mentoring relationship status. RESULTS/ANTICIPATED RESULTS: A total of 49 mentor-mentee teams from 18 departments participated in the training over two cohorts. An upcoming third cohort will be included in the analysis. Overall, 100% mentors and 86% mentees reported the overall value of the program as positive. Post-training, mentees reported an increase in confidence in creating career development plans and articulating career goals. Mentors reported an increase in confidence in providing guidance tailored to mentees needs. Mentees reported improvement in their knowledge of developing personal narratives and handling financial aspects of research; both mentors and mentees reported improvement in insights into achieving work-life balance. Follow up survey results will provide insight into the evolution of the mentoring relationships. DISCUSSION/SIGNIFICANCE: Miami CTSIs mentoring training demonstrated successful participation and positive feedback from mentors and mentees and is poised to become a critical component of the Miami CTSIs research career development pipeline.
507 a. Determining the marginal cost differences and potential areas of improvement for a telerehabilitation versus outpatient occupational therapy session for stroke survivors
Authors: Morrow Corey , Woodbury Michelle , Simpson Kit
Published: April 2022

OBJECTIVES/GOALS: The objective of this study was to estimate the cost differences of a telerehabilitation versus outpatient session. A secondary objective was to identify areas to improve telerehabilitation delivery efficiency. We aim to improve the translation/adoption of telerehabilitation for clinical use. METHODS/STUDY POPULATION: This study used a time-driven activity-based costing (TDABC) approach including 1) observation of rehabilitation sessions and creation of manual time stamps, 2) structured and recorded interviews with two occupational therapists familiar with outpatient therapy and two therapists familiar with telerehabilitation, 3) collection of standard wages for providers, and 4) the creation of an iterative flowchart of both an outpatient and telerehabilitation session care delivery process. This study followed the reporting guidelines to ensure a standardization for TDABC research. RESULTS/ANTICIPATED RESULTS: Overall, telerehabilitation ($225.41) was more costly than outpatient therapy ($168.29) per session for a cost difference of $57.12. Primary time drivers of this finding were initial phone calls (0 mins for OP therapists versus 35 mins for TR) and post documentation (5 mins for OP versus 30 mins for TR) demands for telerehabilitation. DISCUSSION/SIGNIFICANCE: Telerehabilitation is an emerging platform with the potential to reduce costs, improve healthcare inequities, and facilitate better patient outcomes. Improvements in documentation practices, staffing, technology, and reimbursement structuring would allow for a more successful translation.
516 LinkedIn Marketing Strategies to Drive NJ ACTS Regulatory Core Engagement
Authors: Barr Emma , Neubauer Judith , Gelinas Celine
Published: April 2022

OBJECTIVES/GOALS: Our purpose is to promote traffic toward the NJ ACTS Regulatory Cores recently launched website and increase investigator engagement through marketing strategies on LinkedIn. Landscaping to characterize the profiles of researchers on LinkedIn was also completed to estimate the feasibility of engaging with a target population on LinkedIn. METHODS/STUDY POPULATION: Insight gathering was performed to analyze what percentage of researchers possessed a LinkedIn profile and actively used their accounts. A sample population consisting of 284 NJ ACTS members were analyzed to summarize the type of researchers on LinkedIn, and their likelihood of responding to LinkedIn marketing campaigns. Efforts to launch a company LinkedIn page and collect followers were completed. Different methods of promotion were evaluated, including direct vs. mass email outreach to over 600+ researchers at Rutgers. Effectiveness of our platform was measured by comparing/overlaying Regulatory website traffic with LinkedIn traffic, as well as tracking the metrics of LinkedIn posts. RESULTS/ANTICIPATED RESULTS: Among 284 NJ ACTS members, 76% (n=215) possess a LinkedIn profile, but only 21% (n=59) are actively interacting with material on LinkedIn, such as creating, commenting, or sharing posts. Among the NJ ACTS LinkedIn users, 27% of individuals (n=57/215) responded to a direct outreach. Retention of the created organizational page was strong, as most users who visited the Regulatory Core page were likely to become followers. Massive email outreach to 600+ researchers within RBHS did not yield a strong LinkedIn following, however it did result in strong signals of website traffic during the days after the promotion was sent. Engagement with posts on LinkedIn can also be amplified and messaging proliferated when colleagues reshare Regulatory posts on their personal feeds. DISCUSSION/SIGNIFICANCE: 3/4 of academic researchers are likely to be on LinkedIn but may not be active users of the platform. The most effective outreach is through direct messaging as opposed to broader, less individualized tactics (including mass email outreach). Evidence suggests potential to utilize LinkedIn to proactively engage in regulatory-related activities.
