OBJECTIVES/GOALS: To describe preliminary results of Alzheimer’s and dementia caregivers’ (CGs) mobile app use and intention to adopt mHealth apps for their own chronic condition self-management. To discuss implications for designing and implementing mHealth interventions for CGs. METHODS/STUDY POPULATION: This study aims to recruit 110 racially and ethnically diverse family caregivers (CGs) who have a chronic condition, provide care for persons with Alzheimer’s disease or related dementias, and have access to a mobile device. This is a cross-sectional correlational study collecting data with computer-assisted telephone interviews stored through REDCap. The study survey was created using existing surveys about mobile app use; relevant, well-validated research instruments; and questions from the U.S. Census and other national surveys. CGs are being actively recruited from the Baltimore-Washington metropolitan area using various recruitment strategies that have been effective in prior studies. RESULTS/ANTICIPATED RESULTS: The majority of CGs used websites (86%), mobile devices (68%) or apps (53%) to manage their own health. CGs using health-related apps were tracking their exercise (60%), diet (60%), medical records (50%), and physical health measures (50%). More than 4 out of 5 (82%) predicted they would use mobile apps to self-manage their chronic condition, though only 68% actually planned to use them. 86% of CGs were using mobile apps for non-health related purposes, with the most popular app being weather (90%), followed by social media (74%), music/entertainment (68%), and banking/business apps (63%). CGs used weather and social media apps most often (2 or more times/day) and spent 9 hours/week on apps. DISCUSSION/SIGNIFICANCE OF IMPACT: Websites and mobile apps appear to be feasible modes to deliver health interventions to CGs. Researchers should consider including features of apps most frequently used by CGs, such as the weather, ways to connect with others, and music/entertainment, when delivering mHealth interventions to CGs.

OBJECTIVES/GOALS: Policy makers are interested in understanding scientific collaborations that translate knowledge into population health. The objective of this study is to compare the translational research collaboration of the Hispanic Alliance of Clinical and Translational Research in 2020 and 2023 by using Social Network Analysis (SNA). METHODS/STUDY POPULATION: We conducted a systematic document review of all the Hispanic Alliance Calls for Pilot Projects from 2020 to 2023 including key attributes of the investigators and collaborators such as academic institution, highest degree, and collaborator type. Scientific collaboration was defined as two or more researchers working together in grant proposal for a pilot project application. Study data was recorded and tracked using an Excel spreadsheet. R Statistical software was used to analyze and map the networks resulting from collaboration interactions comparing the 2020 Call and 2023 Call. Network statistics were performed including nodes, isolates, edges, components, density, diameter, average degree, and the size of the main component. RESULTS/ANTICIPATED RESULTS: A total of 134 investigators comprised the overall network. The network are predominantly clinician (49.3%) and basic researchers (25.4%). Preliminary results shows that diversity of disciplines and affiliations in the collaborative relationships increased across time. Findings demonstrated that the number of nodes/actors increased from 16 to 65 comparing 2020 to 2023 and the edges/relationships from 12 to 53. The number of translational research cluster increased from 4 to 13 comparing 2020 to 2023. More extensive collaborative cluster occurred across time with over 15 researchers collaborating. A mentor was the key player connecting these research clusters. DISCUSSION/SIGNIFICANCE: This study provides critical data to mapping the IDeA CTR translational research collaboration patterns. Research collaboration increased across time. This innovative approach serves to foster data-driven decision-making to enhance collaboration, diversity, and program outcomes. It offers valuable insights for policy and practice.

Within Wisconsin, our residents experience some of the worst health disparities in the nation. Public reporting on disparities in the quality of care is important to achieving accountability for reducing disparities over time and has been associated with improvements in care. Disparities reporting using statewide electronic health records (EHR) data would allow efficient and regular reporting, but there are significant challenges with missing data and data harmonization. We report our experience in creating a statewide, centralized EHR data repository to support health systems in reducing health disparities through public reporting. We partnered with the Wisconsin Collaborative for Healthcare Quality (the “Collaborative”), which houses patient-level EHR data from 25 health systems including validated metrics of healthcare quality. We undertook a detailed assessment of potential disparity indicators (race and ethnicity, insurance status and type, and geographic disparity). Challenges for each indicator are described, with solutions encompassing internal (health system) harmonization, central (Collaborative) harmonization, and centralized data processing. Key lessons include engaging health systems in identifying disparity indicators, aligning with system priorities, measuring indicators already collected in the EHR to minimize burden, and facilitating workgroups with health systems to build relationships, improve data collection, and develop initiatives to address disparities in healthcare.

The Advancing the Science of Mentorship: Future Directions for Sustainable Implementation and Evaluation of Mentorship Education for the Clinical and Translational Science Workforce conference was held in Madison, Wisconsin, in April 2023. The conference provided an engaging and scholarly forum for clinical and translational researchers from diverse backgrounds and career stages (including leaders at Clinical and Translational Science Award (CTSA) hubs and affiliated institutions) with a professional interest and commitment to improving and diversifying workforce development and fostering a climate of inclusive excellence through best practices in mentorship. Outcomes from the conference include an online resource and a new Community of Practice.

OBJECTIVES/SPECIFIC AIMS: To compare functional differences in WJ-MSCs-derived from term Versus preterm infants. METHODS/STUDY POPULATION: WJ-MSCs were enzymatically digested from umbilical cord tissue from Term (gestational age ≥37 wk, n=4) and Preterm (gestational age ≤32 wk, n=5) neonates. Cells were characterized by (1) surface antigen markers using flow cytometry, (2) ability to differentiate into adipogenic, chondrogenic, and osteogenic lineages following in vitro stimulation, (3) colony forming unit efficiency, (4) proliferation rates, and (5) cell motility assay. RESULTS/ANTICIPATED RESULTS: WJ-MSCs were successfully isolated from both Preterm and Term groups. Cells adhered to plastic and displayed characteristic spindle-shaped morphology when cultured under standard conditions. WJ-MSCs from both groups expressed surface antigen markers CD73, CD90, and CD146 (≥90%) and did not express hematopoietic markers HLA-DR, CD79, or CD117 (<5%). Preterm and Term cells were capable of differentiating into osteogenic, chondrogenic, and adipogenic lineages. There were no significant differences between the groups when evaluated by colony forming efficiency, proliferation rates, or cell motility. DISCUSSION/SIGNIFICANCE OF IMPACT: These preliminary findings suggest that WJ-MSCs derived from full-term or preterm neonates have similar functional characteristics. Future studies will focus on the regenerative potential of WJ-MSCs from preterm and term infants following changes in the microenvironment (eg, oxygen tension, inflammatory stimulation).

OBJECTIVES/SPECIFIC AIMS: The Life’s Simple 7 (LS7) metric was created by the American Heart Association with the goal of educating the public on seven modifiable factors that contribute to heart health. While it is well documented that these ideal health behaviors lower risk of cardiovascular disease (CVD) in the general population, the association between the LS7 ideal health metrics and end stage renal disease (ESRD) risk has not been examined in a lower socioeconomic population at high risk for both ESRD and CVD. Our objective is to examine the association between the LS7 score and incident ESRD in a cohort of white and black men and women in the southeastern US, where rates of CVD and ESRD are high. METHODS/STUDY POPULATION: The Southern Community Cohort Study recruited ~86,000 low-income blacks and whites in the southeastern US (2002-2009). Utilizing a nested case-control design, our analysis included 1628 incident cases of ESRD identified via linkage of the cohort with the United States Renal Data System (USRDS) from January 1, 2002 to March 31, 2015. Controls (n = 4884) were individually matched 3:1 with ESRD cases based on age, sex, and race. Demographic, medical, and lifestyle information were obtained via baseline questionnaire. The AHA definitions for ideal health were used for non-smoking (never or quit >12 months), body mass index (BMI<25kg/m2) and physical activity (>75 min/week of vigorous physical activity or >150min/week of moderate/vigorous activity). Modified definitions were used for consuming a healthy diet [Healthy Eating Index (HEI10) score>70] and for blood pressure, fasting plasma glucose, and total cholesterol, based on self-reported no history of diagnosis of hypertension, diabetes, and hypercholesterolemia, respectively. The number of ideal health parameters were summed to generate the LS7 score, which ranged from 0-7 with higher scores indicating more ideal health. Adjusted odds ratios (95% confidence intervals) for incident ESRD associated with LS7 score were calculated using conditional logistic regression models, adjusting for income and education. The SCCS ESRD case-cohort dataset will be available by TS 2019 and analyses will be completed to adjust for baseline estimated glomerular filtration rate (eGFR) as a marker of kidney function and to examine whether eGFR modifies the relationship between LS7 and incident ESRD. RESULTS/ANTICIPATED RESULTS: At baseline, mean age was 54 years, 55% (3600) of participants were women, and 87% (5656) were black. A total of 58% (943) of ESRD cases were non-smokers compared to 54% (2633) of controls. ESRD cases had higher prevalence of BMI>25 kg/m2 (81% vs. 74%), hypertension (84% vs. 59%), hypercholesterolemia (48% vs. 34%), and diabetes (66% vs. 22%) compared to controls. A total of 18% (839) of controls and 12% (194) of ESRD cases met ideal exercise recommendations, and 20% of either cases (302) or controls (916) had a HEI10 score above 70. The median LS7 score for controls and ESRD cases was 3 and 2, respectively, and 17% (983) of participants had a low score (0-1) while 2% (105) met 6 or 7 ideal health metrics. Higher LS7 score was associated with lower odds of ESRD (P-trend<0.001). Participants with LS7 score >3 (above median) had 75% reduced odds of ESRD (OR 0.25; 95% CI 0.22, 0.29) compared to those with a score of 2 or less. DISCUSSION/SIGNIFICANCE OF IMPACT: In the SCCS population, the presence of any 3 or more ideal health behaviors is associated with reduced odds of developing ESRD. The components of the LS7 represent important modifiable risk factors that may be targets for future interventions driven by the patient. The attributable risk due to each factor is needed to dissect which ideal behaviors are the most beneficial.

OBJECTIVES/SPECIFIC AIMS: We hypothesize that both NGF and TNF-α contribute to oral cancer pain by upregulating pro-nociceptive inflammatory cytokines. METHODS/STUDY POPULATION: In total, 48 oral cancer patients were evaluated and their pain scores were measured using a validated oral cancer pain questionnaire. Presence of perineural invasion (PNI) was identified from patients’ pathology reports. We utilized The NIH Cancer Genome Atlas (TCGA) Head and Neck Cancer cohort to investigate the association between pain and genes related to NGF, TNF-α, and their receptors (TRKA, P75, TNF-α receptor 1, and TNF-α receptor 2) in oral cancer samples by employing PNI as a surrogate for pain. Demographic characteristics, clinical characteristics, and genes were analyzed using logistic regression models. A xenograft cancer pain model was created by inoculating human oral cancer cells (HSC-3) into the mouse hind paw. Mice (n=6 per group) were treated with anti-NGF alone, anti-TNF-α alone, a combination of anti-NGF and anti-TNF-α, or PBS (vehicle control). Nociceptive behaviors were measured using an electronic paw withdrawal assay. Paw volume was measured using a plethysmometer. Cytokines in the paw tissues were measured using a multiplex assay kit with 28 cytokines. RESULTS/ANTICIPATED RESULTS: Oral cancer patients with PNI report significantly more pain compared with patients without PNI in our patient cohort (p<0.05). From analysis of TCGA data, we found that PNI is significantly associated with lymphovascular invasion, pathological nodal invasion, and pathological tumor staging (all p<0.05). In adjusted models, we observed that the NGF receptor p75NTR (NGFR) and the TNF-α receptor 1 (TNFRSF1A) were associated with PNI (both p<0.05) and significantly correlated to each other (r=0.25, p<0.001). High levels of TNF-α were present in HSC-3 cell lines and the mouse xenograft cancers. In mice with cancer pain, combined treatment with anti-NGF and anti-TNF-α together provided more effective pain control compared with either anti-NGF or anti-TNF-α treatment alone (p<0.05). We found significantly increased levels of MIP3a, IL-1b, IL-2, IL-4, IL-28b, IL-23, IL17a, IL-31, and IL-33 in cancer mice compared with normal mice (all p<0.05). The combination therapy significantly reduced cytokines MIP3a, IL-1b, IL-4, IL-28b, IL-31, and IL-33 (all p<0.05). DISCUSSION/SIGNIFICANCE OF IMPACT: We show that targeting both NGF and TNF-α provides more effective pain relief in an oral cancer model. These results suggest that therapeutic strategies aimed at both pathways could yield improved pain management for oral cancer patients.

ABSTRACT IMPACT: The development of marketing materials such as flyers and brochures will ultimately be used to promote integration of special populations who are traditionally underrepresented into research by informing and attracting scholars and investigators of available consultative and analytic services that are provided by the ISP Core staff. OBJECTIVES/GOALS: The development of informative and memorable marketing materials is to increase awareness of the ISP Core and its service functions to help with the integration of special populations, as well as promoting scholar and investigator use of these services. METHODS/STUDY POPULATION: After assessing how many CTSA hubs market their ISP services, a flyer and brochure were developed using Adobe InDesign to include information commonly found on CTSA hubs. Flyers and brochures were chosen because they make information physically available outside of a website and be sent to email listservs, making it possible to reach more scholars and investigators. The marketing materials will contain sections to explain the purpose of NJACTS and the ISP Core, list related special populations and available service functions, introduce the ISP Core leadership team, provide examples of past consulting work and contact information for investigators to request service consultations. Flyers will be emailed digitally to listservs and distributed physically along with printed tri-fold brochures to investigators. RESULTS/ANTICIPATED RESULTS: The primary anticipated result from the development of marketing materials include an increased awareness and utilization of ISP Core services and an increased inclusion of special populations in research with NJACTS. The impact of these marketing materials maybe assessed by providing investigators with a short survey when ISP services are requested, which will ask how investigators learned about ISP and its services. DISCUSSION/SIGNIFICANCE OF FINDINGS: Through the work of creating physical marketing materials, the ISP Core will have a method to effectively distribute information about its services, ultimately promoting investigators at all stages to integrate special populations into their research.

OBJECTIVES/SPECIFIC AIMS: Many CTSA programs have implemented curricula leading to clinical investigation master’s degrees. Evaluation of long-term outcomes for graduates can support curriculum improvement. METHODS/STUDY POPULATION: We evaluated graduates 1–3 years post completion of an MS in Clinical Investigation at the University of Utah. We administered the 12-item Clinical Research Appraisal Inventory (CRAI-12) describing confidence in ability to perform research tasks; we derived 6 CRAI sub-scales. Additional questionnaire items assessed current engagement in research, including percent of effort devoted to research and level of involvement in research projects using specific research methods. RESULTS/ANTICIPATED RESULTS: Graduates reported high confidence for the CRAI domain of reporting, interpreting, and presenting (on a scale of 0–20, mean 17.9±SD 1.9) and the domain of conceptualizing and collaborating (16.5±2.2) on research projects; confidence was somewhat lower in the domains of planning (14.6±3.3) and funding (14.9±2.8) projects. Graduates’ estimated current professional effort devoted to research had a median of 32%, interquartile range (IQR) 20%–70%; among graduates with clinical responsibilities, median effort devoted to research was 23%, IQR 15%–45%. In total, 74% of graduates reported moderate or high involvement in research using existing large databases, 46% reported moderate or high involvement in comparative effectiveness research, and 54% reported moderate or high involvement in quality improvement. DISCUSSION/SIGNIFICANCE OF IMPACT: A majority of clinical investigation graduates remain engaged in research but most are able to devote less than one-third of professional effort to research. Evaluation of clinical investigation graduates who have moved into their research careers can inform program directors about domains of research expertise and methodological areas that may merit additional emphasis in the curriculum.

OBJECTIVES/SPECIFIC AIMS: This study (1) investigated the presence and severity of autonomic nervous system (ANS) dysfunction in patients with pre-symptomatic Huntington Disease (HD) and (2) determined if pharmacologic manipulation of the ANS could modify the progression of HD. METHODS/STUDY POPULATION: Using a unique data set of children at-risk for HD (the Kids-HD study), markers of autonomic function (resting heart rate [rHR], blood pressure [BP], and core body temperature [CBT]) were compared between pre-symptomatic, gene-expanded children (psGE) and healthy developing children using mixed models analyses controlling for sex, age, and body mass index. Included participants had to be < 18 years old and be at least 10 years from their predicted motor diagnosis of HD. Using the Enroll-HD database, inverse-propensity score weighted, Cox Regression analyses investigated the effects of beta-blockers on the timing of motor diagnosis of presymptomatic, adult patients with HD. RESULTS/ANTICIPATED RESULTS: Compared to healthy controls, the psGE participants had significantly (p<0.05) higher mean rHR, systolic BP percentile, and CBT compared to the healthy controls (elevated by 4.01 bpm 0.19°C, and 5.96 percentile points, respectively, in the psGE group). Participants from Enroll-HD who were using a beta-blocker prior to motor diagnosis (n=65) demonstrated a significantly lower annualized risk of motor diagnosis [HR=0.56, p=0.03], compared to other participants with HD (n=1972). DISCUSSION/SIGNIFICANCE OF IMPACT: Sympathetic nervous system activity is elevated in patients with HD decades prior to their predicted motor diagnosis. Furthermore, modulation of the sympathetic nervous system with beta-blockers significantly lowers the annualized risk of motor diagnosis of HD.

OBJECTIVES/SPECIFIC AIMS: Transgender individuals remain an underserved population with a unique set of healthcare needs. Given the recent increase in demand for gender affirmation surgery, there is a need to train urologists in the various aspects of surgical management of transgender patients. It is unclear how many urologic residency programs are participating in transgender care. In this study, we sought to determine the current status of urologic training programs in the delivery of transgender care and the sentiments regarding the current and future need to train urologists. METHODS/STUDY POPULATION: Between June and August 2017, a 22 item cross-sectional survey was emailed to all 138 program directors (PDs) as listed by the ACGME. Participation was voluntary and responses were anonymous. Statistical analysis was performed using SAS version 9.4. RESULTS/ANTICIPATED RESULTS: In total, 48 PDs completed the survey (36% of US PDs) and 1 declined to participate. All AUA regions had at least 25% representation, except the Western region (13%). In total, 42% of urology programs that responded participate in institutional transgender health programs; 76% of PDs believe there is a current or future need to train urology residents in the surgical care of transgender patients. PDs were significantly more likely to endorse a need for transgender training if their institution has a transgender health program (95% vs. 58%, p<0.005). Similarly, expressed interest in transgender care by trainees was associated with increased belief among PDs in the need for transgender training (95% vs. 58%, p<0.005). There was also an association between the presence of a transgender health program and trainee interest in transgender care (64% vs. 33%, p=0.04). Need for resident training in the following procedures was cited most often by PDs: complicated catheter placement (91%), orchiectomy (89%), urethral fistula repair (82%), penile/testicle prosthesis insertion (77%), phalloplasty (69%), vaginoplasty (66%), and metoidioplasty/urethral lengthening (54%). Despite the overall consensus that residents should be trained in transgender care, 83% of PDs responded that urologic transgender surgery should be trained in fellowship rather. DISCUSSION/SIGNIFICANCE OF IMPACT: There is an increased demand for surgeons competent in providing gender affirmation surgery. The majority of urology residency PDs believe in the need to train residents in the surgical care of transgender patients. A formalized curriculum for the urologic management of transgender patients should be instituted across residency programs to ensure adequate exposure and competency.

OBJECTIVES/SPECIFIC AIMS: To assess the efficacy of exogenous administration of MSCs in animal models of HIE. METHODS/STUDY POPULATION: Adhering to the Systematic Review Protocol for Animal Intervention Studies, a systematic search of English articles was performed using MEDLINE, Web of Science, CINAHL, and Google Scholar. Search term items included mesenchymal stem/stromal cell, hypoxic ischemic encephalopathy, asphyxia, cerebral ischemia, and neonatology. We selected randomized and nonrandomized studies that examined in vivo neonatal models of induced HIE. We excluded studies that combined MSCs with an adjunct therapy. Data were collected on study specifics, MSC characteristics, and outcome measurements. The primary outcome was efficacy of MSC treatment, assessed by functional neurologic measures (cognitive, motor, sensory). Risk of bias was assessed using the SYRCLE’s risk of bias tool and we used the ARRIVE guidelines to describe the quality of study reporting. RESULTS/ANTICIPATED RESULTS: A total of 17 preclinical publications focusing on MSC therapy for HIE met our inclusion criteria. Fifteen of the studies (88%) induced HIE in rodents by ligating the common carotid artery followed by a period of hypoxic exposure. Nine (53%) studies derived their MSCs from rodent bone marrow, whereas the other investigators provided xenografts from human bone marrow or umbilical cord-derived MSCs. Range of MSC dose was between 0.25 and 3.5× 106 cells with 71% of the experiments transplanting the MSCs intranasally or intracerebral. Three studies (18%) administered multiple doses. The cylinder rearing test was the most common (73%) sensorimotor functional outcome performed in the first month following the establishment of HIE. All studies demonstrated a reduction in asymmetrical paw preference after receiving MSC therapy. Lesional size was assessed, using neuroimaging or histologic evaluations, and the majority of studies showed a decreased insult following MSC therapy. DISCUSSION/SIGNIFICANCE OF IMPACT: MSC treatment demonstrates improved functional and structural outcomes that are encouraging for future translational studies.

OBJECTIVES/GOALS: An academic medical library evaluated an EHR data abstraction service by assessing uptake and publication metrics, including use by department, purpose of data abstraction requests and publication counts. METHODS/STUDY POPULATION: The evaluation included 167 requests for EHR data processed by the institution’s clinical research data management unit (CRDMU) and recorded in an intake form hosted on REDCap. These requests originated from various departments. The intake forms collected investigator and study information, as well as request completion dates. Information in the intake forms were matched with publications and meeting abstracts that were indexed in a database of faculty publications. Investigators who submitted EHR data requests that could not be readily matched to publications were contacted to verify the status of their studies and any associated publications. RESULTS/ANTICIPATED RESULTS: The evaluation included 167 data requests submitted to the CRDMU between 2016 and 2018. These requests were categorized into the following use cases: retrospective studies (n=93); patient recruitment (n=50); and 'other' (i.e., education, training, or process improvement; feasibility assessments; machine learning (n=14)). By the end of the evaluation period, an average of four years after the data requests were submitted to the CRDMU, 60 of all 167 EHR datasets (35.9%) led to publications as articles or meeting abstracts. 64.5% of the EHR datasets requested for retrospective studies, 56% of the datasets requested for recruitment, and 79.1% of datasets requested for other uses did not lead to publications. DISCUSSION/SIGNIFICANCE: These findings offer evidence that bibliometrics alone provide limited insight into the value of services and data utilized for secondary research. Data ecosystem stakeholders are encouraged to consider—and develop—scalable, reproducible, and more holistic assessments of the impact of their services.

ABSTRACT IMPACT: Development and implementation of a parent navigator program to help parents of justice-involved youth could assist parents in navigating the justice system, improve engagement with court and probation, and ultimately improve outcomes for youth involved in the juvenile justice system OBJECTIVES/GOALS: The goals of the study are to (1) develop a parent-peer navigator program utilizing community-based participatory design; and (2) implement and assess the feasibility of a parent peer navigator program in an urban juvenile justice system. METHODS/STUDY POPULATION: The EPIS framework will guide development and implementation of the navigator program as well as measurement of the implementation process, including measurements of feasibility and acceptability. In the Exploration phase, qualitative interviews with juvenile justice staff, parents of justice-involved youth, and members of the local family advisory board will inform program needs. In the preparation stage, I will work closely with the family advisory board to develop the actual parent navigator program protocol, including a training plan for navigators and their specific roles. I will conduct an open trial in the implementation phase, measuring program feasibility and acceptability among parents, navigators, juvenile justice staff, parents, and youth utilizing mixed methods. RESULTS/ANTICIPATED RESULTS: Results will inform feasibility of implementing the program as well as acceptability of the program based on mixed methods data from parents of justice-involved youth, juvenile justice staff, family advisory board members, and other community stakeholders. Results will potentially inform conduct of a larger scale pilot hybrid implementation-effectiveness study. DISCUSSION/SIGNIFICANCE OF FINDINGS: Development and implementation of a parent navigator program to help parents of justice-involved youth could assist parents in navigating the justice system, improve engagement with court and probation, and ultimately improve outcomes for youth involved in the juvenile justice system.

OBJECTIVES/GOALS: This presentation outlines a novel approach to evaluating multiple risk factors for the development of dose-limiting toxicities in adolescents and young adults with cancer. This is the first to evaluate biobehavioral predictors originally identified in animal models in clinical human studies. METHODS/STUDY POPULATION: Adolescents and young adults (AYAs) have seen the slowest improvements in cancer survival and have some of the highest rates of dose-limiting mucositis (mouth sores). AYAs receiving chemotherapy with a significant chance of dose-limiting mucositis were recruited for a prospective study. Baseline perceived psychologic stress levels and inflammatory markers were collected at the time of chemotherapy administration and participants completed a daily assessment of mucositis for 14 days following chemotherapy. Logistic regression will be used to evaluate stress and inflammation as predictors of mucositis and Sobels testing will evaluate the role of inflammation as mediators in this relationship. RESULTS/ANTICIPATED RESULTS: We anticipate that, as seen in animal models, stress and inflammation will predict mucositis development. First, we hypothesize that stress levels and inflammatory markers will have a direct correlation and that the level of inflammation at the time of chemotherapy administration will predict mucositis incidence and severity. Through mediation testing, we hypothesize that inflammatory markers will explain a significant amount of the variance in mucositis also explained by stress, identifying inflammation as a mediator in this relationship. In all, we expect that stress and inflammation both predict mucositis development and will be identified as important modifiable factors that can be altered to reduce the risk of toxicity development during cancer therapy. DISCUSSION/SIGNIFICANCE: This work intends to evaluate predictors of chemotherapy-related toxicity development in AYAs with cancer and identify areas of intervention that will reduce toxicity profiles and close the gap in cancer survival for AYAs. Findings are applicable to biomedical, nursing, and psychosocial professionals and will inform future, large clinical studies

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.

OBJECTIVES/GOALS: Recruiting under-resourced, rural nursing home (NH) staff to clinical research has proven especially difficult during COVID-19. The goal for this study was to leverage an existing group of NH providers to seek their opinions on the development of a novel person-centered risk management intervention for residents with dementia. METHODS/STUDY POPULATION: This study used community engagement studios (CES) to connect and engage with community experts (NH staff and leaders) attending, or in close vicinity to, a NH provider conference in Denver, Colorado July 25-30, 2022. Led by an experienced moderator and an assistant moderator using a semi-structured discussion guide, two CES were completed with 14 community experts. Community experts took part in a 90-minute facilitated and recorded discussion to gain their perspectives on the DIGNITY (Decision-making in aging and dementia for autonomy) study procedures and instruments along with recommendations for how to improve the acceptability, feasibility, and likelihood of intervention success. The local IRB determined this study to not be human research. RESULTS/ANTICIPATED RESULTS: Community experts most often identified as white/Caucasian (64%) females (93%) holding jobs in NHs as direct-care nurse/nursing aide (n=5), nurse supervisor/director (n=4), other NH leadership (n=3), nursing aide union organizers (n=2), and state surveyor (n=1). The primary outcomes of the CES were suggestions that could be used to adapt the elements of the study design. Following CESs, transcripts were reviewed and summarized on a rapid feedback table. The study team made changes to five of the six intervention elements based on expert feedback. Most experts (79%) agreed that the DIGNITY intervention was acceptable, appropriate, and feasible to implement in the NH community. DISCUSSION/SIGNIFICANCE: This study highlighted the voices of NH staff and leaders that is often underrepresented in research development and provides critical information for how to adapt a novel intervention for future testing in rural NH communities. Results also support the usefulness of CES as a method to develop practical interventions in NH communities.

OBJECTIVES/GOALS: Premature birth and its complications are among the largest contributions to infant death within the US. The rates of premature birth and infant death are significantly higher among African Americans. Therefore, there is an urgent need to understand the biological and social drivers of this health disparities to improve birth outcomes. METHODS/STUDY POPULATION: This is a retrospective cohort study of premature infants (< 28 weeks estimated gestational age, birth weight < 1500g) born within 2018 and 2021 to mothers who identify as either African American, or White/Caucasian Non-Hispanic and are cared for at Saint Louis Children’s Hospital Neonatal Intensive Care Unit. EPIC collected data will include maternal and fetal factors and social determinants of health (SDOH). ICD-9, ICD-10 codes for primary outcomes include grade 3-4 Interventricular Hemorrhage, moderate-severe Bronchopulmonary Dysplasia, Stage 2+ Necrotizing Enterocolitis, and moderate-severe Retinopathy of Prematurity. Will develop a composite variable score using the SDOH for risk/no risk using that for each disease outcome and mortality. Will use Chi-square test or T-test to compare groups. RESULTS/ANTICIPATED RESULTS: We are currently in the data collection phase of the study, but we anticipate seeing an increase in risk of all-cause morbidity as well as all-cause mortality for infants born to Black mothers compared to infants born to White mothers. We anticipate higher levels of disadvantage (increased area deprivation scores) and lower access to the goods and services deemed necessary for appropriate care of Black mothers and subsequent relation to outcomes for their infants. DISCUSSION/SIGNIFICANCE: Following analysis and assessment of that analysis we will discuss these findings and the impact on the general population and the needs for improvement and implementation of interventions upstream in the care of the vulnerable and special mother-baby-dyad population.
