OBJECTIVES/GOALS: Engagement with art may reduce the social disconnection that accompanies chronic pain. Disaggregating specific from non-specific effects of arts-based programs is challenging. This study creates an experimental virtual museum to identify the separate and joint effects of art and social connection. METHODS/STUDY POPULATION: Two x two factorial experiment with repeated measures: (1) Artwork present condition is a virtual exhibition featuring paintings from the Google Arts & Culture collection; (2) Artwork absent condition is the same exhibition space but with the paintings removed; (3) Social connection condition asks participants to write about a situation in which they felt more socially connected to others; (4) Social disconnection conditions asks participants to write about a situation in which they felt more socially disconnected from others. Participants: (1) English language proficiency; (2) ≥18 years; (3) Chronic moderate to severe pain; (4) Lonely; (5) Has electronic device with internet connection. RESULTS/ANTICIPATED RESULTS: Participants will be recruited through a 3-month social media campaign conducted by StudyPages, a clinical trial recruitment and management platform. This study will evaluate the effects of virtual art exposure and social connectivity priming on pain and social disconnection reduction among lonely IWCP. Pre-intervention scores for pain intensity, pain unpleasantness, and perceived social disconnection will be compared to post-intervention scores. Secondary outcome measures include (a) Museum visit data (e.g., user movement, click, object interaction, open comments) and (b) perceptions about artwork. DISCUSSION/SIGNIFICANCE: Psychosocial support for IWCP may improve pain-related outcomes. This studys data will help to optimize virtual museum interventions and provides the first data we are aware of to evaluate the specific effects of art in virtual museum engagement to reduce pain and social disconnection among IWCP.

Despite the adversity presented by COVID-19 pandemic, it also pushed for experimenting with innovative strategies for community engagement. The Community Research Advisory Council (C-RAC) at Johns Hopkins University (JHU), is an initiative to promote community engagement in research. COVID-19 rendered it impossible for C-RAC to conduct its meetings all of which have historically been in person. We describe the experience of advancing the work of the C-RAC during COVID-19 using digital and virtual strategies. Since March 2020, C-RAC transitioned from in person to virtual meetings. The needs assessment was conducted among C-RAC members, and individualized solutions provided for a successful virtual engagement. The usual working schedule was altered to respond to COVID-19 and promote community engaged research. Attendance to C-RAC meetings before and after the transition to virtual operation increased from 69% to 76% among C-RAC members from the community. In addition, the C-RAC launched new initiatives and in eighteen months since January 2020, it conducted 50 highly rated research reviews for 20 research teams. The experience of the C-RAC demonstrates that when community needs are assessed and addressed, and technical support is provided, digital strategies can lead to greater community collaborations.

OBJECTIVES/GOALS: Predictive models for health outcomes often have poor calibration potentially due to interactions that are ignored by standard methods. Using AHRQ models for Inpatient Quality Indicator (IQI) 11 Abdominal Aortic Aneurysm Repair and IQI 09 Pancreatic Resection mortality, we hypothesize that identifying interactions may improve model calibration. METHODS/STUDY POPULATION: We used adult discharge data from 16 states obtained from AHRQ Healthcare Cost and Utilization Project (State Inpatient Database), California Department of Health Care Access and Information, and New York State Department of Health. We used AHRQ’s v2021-1 Clinical Classifications Software Refined (CCSR) with present on admission flags to create features for risk-adjustment. We compared the performance of Least absolute shrinkage and selection operator (LASSO) model and first-order interaction models estimated using Hierarchical Group Lasso Regression (HGLR), after splitting the data into training and test sets. C-statistics, area under the precision-recall curve and Hosmer-Lemeshow calibration plots are reported. Finally, logistic regression models with selected CCSRs were evaluated on the test set. RESULTS/ANTICIPATED RESULTS: IQI 11 has four strata: open and endovascular repair of ruptured aneurysms (39% and 21% mortality, respectively); open and endovascular repair of unruptured aneurysms (6% and 0.8% mortality, respectively). IQI 09 has two strata: with and without pancreatic cancer (2% and 2.5% mortality, respectively). Comparing the HGLR model (with interaction effects) with Lasso models (without interactions), we noticed meaningful improvements in discrimination and calibration. However, for IQI 09, the extremely low mortality rate did not result in good HGLR or LASSO models. Interactions involving CCSRs could be identified using the novel HGLR method, which improved model performance given a heterogeneous population in IQI 11 with a mix of high and low event rates, unlike the more homogeneous patient population in IQI 09. DISCUSSION/SIGNIFICANCE: Standard implementations of regression models fail to address critical issues that arise in healthcare data – (a) quadratic explosion of potential interactions that cannot be manually identified, and (b) categorical variables with multiple levels or values (e.g., age categories). We propose innovative use of HGLR to robustly address these issues.

OBJECTIVES/GOALS: To determine if decellularized costal cartilage (DCC), which could theoretically be obtained “off the shelf,” would provide similar results to autologous cartilage grafts previously studied in this lab, thereby widening the application of our novel nipple engineering approach to all patients undergoing nipple reconstruction. METHODS/STUDY POPULATION: PLA scaffolds (diameter: 1.0 cm, height: 1.0 cm) were printed using a PRUSA 3D printer and sterilized. Lamb costal cartilage was minced (1 mm3) or zested (<0.2 mm3) and then decellularized. The quality of decellularization was assessed using DNA quantification and histological analysis. DCC was then packed into PLA scaffolds and implanted subcutaneously into immunocompetent Sprague Dawley rats using a CV flap technique. The constructs were explanted and evaluated up to 6 months after implantation. RESULTS/ANTICIPATED RESULTS: All nipple reconstructions showed well-preserved diameter and projection due to persistence of the external scaffolds at 1, 3, and 6 months. Mass and volume of engineered tissue was well-preserved over all timepoints. Compared to implantation values, engineered zested nipples demonstrated a 12% mass increase and a 22% volume increase at 6 months. Minced nipples illustrated a similar mass and volume gain with a 21% increase in mass and a 13% increase in volume at 6 months secondary to infiltration of fibrovascular tissue and growth through scaffold wall pores, respectively. Histologic analysis demonstrated a mild inflammatory infiltrate 1 month after implantation which was replaced by fibrovascular tissue by 3 months that remained stable through 6 months. The processed DCC structure remained unchanged over time. DISCUSSION/SIGNIFICANCE: Using acellular ovine xenograft within bioabsorbable scaffolds, we have engineered neonipples that maintain their volume for at least 6 months. DCC architecture is well-preserved with minimal evidence of immune-mediated degradation. By using DCC, this novel approach to nipple engineering may be applied to any patient requiring reconstruction.

OBJECTIVES/GOALS: While CTSA hubs have contributed to the successes in COVID-19 clinical research, understanding the role of the CTSA consortium in translating vaccine efficacy and availability to awareness and implementation. The goal of this study is to quantitatively assess the use of social media in the dissemination of COVID 19 vaccine content across 60+ CTSA Hubs. METHODS/STUDY POPULATION: Structured search terms in the CTSA Search Solutions database were used to identify CTSA Hub website pages highlighting “COVID-19 Vaccination Information.” Each link identified was manually reviewed for vaccination content. The links and content identified by CTSA Search Solutions were then validated by advanced Google search operator “vaccine site” and manual review of CTSA Hub websites. Official CTSA Hub social media platforms were searched for vaccine proliferation content from January 1, 2020 to November 11, 2021. Data points collected included Community Targeted Vaccine Content, Vaccine Awareness, Vaccine Distribution, Vaccine Clinical Trial, Vaccine Related Media, Social Media Presence, and Social Media Vaccine Proliferation. RESULTS/ANTICIPATED RESULTS: In examining content, of the 64 listed CTSA Hubs, 52 of (67.2%) hosted one or more categories of COVID-19 vaccine information, and 16 (25%) hosted three or more categories. The most common category was “Community Targeted Information” with 27 (42.2%) hubs; the least common category was “Vaccine Distribution” with 5 (7.8%) hubs. Examining social media for vaccine proliferation, 41 (64.1%) hubs had connected social media and 23 (35.9%) hubs had vaccine proliferation posts. The most common platform was Twitter with 37 hubs; the least common platform was Instagram with 5 hubs. DISCUSSION/SIGNIFICANCE: Our investigation demonstrated varying Phase 4 translational efforts via social media among the CTSA Hubs for COVID-19 vaccine implementation. These novel findings identify promising opportunities for enhancement while emphasizing proven strategies from CTSA hubs nationwide. Further research will elucidate granular trends among CTSA hubs.

OBJECTIVES/GOALS: The objectives of this study are to: 1) Examine the feasibility of using concurrent multi-methodology to quantify the affective, decisional, physical symptom domains of Family Intensive Care Unit Syndrome. 2) Describe the associations between the Family Intensive Care Unit Syndrome symptom domains (affective, decisional, physical). METHODS/STUDY POPULATION: Using a repeated-measures, correlational design, we recruited surrogate decision makers of incapacitated, mechanically ventilated patients within four adult intensive care units at a tertiary medical center in northeast Ohio. We collected baseline data (T1) after obtaining informed consent and follow-up data three (T2) and seven (T3) days post-baseline. We used self-report instruments, behavioral tasks, and accelerometry to measure affective (anxiety & depression), decisional (working memory ability & decision fatigue), and physical (sleep quality & sleep disturbance), symptom domains. For objective 1, we computed completion percentages of each time-point and overall compliance with wearing the accelerometer device. For objective 2, we inspected Spearman correlations. RESULTS/ANTICIPATED RESULTS: We recruited and collected baseline data (T1) for 33 participants. Nineteen participants completed the T2 interview and twenty participants completed T3. Eight participants wore the accelerometer device for less than 72 hours and 15 wore the accelerometer for the full study period. At baseline, the physical symptoms (sleep quality & disturbance) were strongly correlated with the affective (anxiety & depression) symptoms, all of which were moderately correlated with one decisional symptom (decision fatigue). One cognitive symptom (working memory dysfunction), was weakly associated with the affective and physical symptom domains, and moderately correlated with the other cognitive symptom (decision fatigue) These associative trends were maintained within and between each time point. DISCUSSION/SIGNIFICANCE: This study identifies potential opportunities for examining the various symptom domains of Family Intensive Care Unit Syndrome. The associations between the domains are consistent with the extant literature, and highlights the need for supportive interventions that mitigate affective and physical symptoms that can compromise decision-making.

In 2020, Baylor College of Medicine held a datathon to inform potential users of a new data warehouse, allow users to address clinical questions, identify warehouse capabilities and limitations, foster collaborations, and engage trainees. Senior faculty selected proposals based on feasibility and impact. Selectees worked with Information Technology for 2 months and presented findings. A survey of participants showed diverse levels of experience, high perceived value of the datathon, high rates of collaboration, and significant increases in knowledge. A datathon can promote familiarity with a new data warehouse, guide data warehouse improvement, and promote collaboration.

OBJECTIVES/GOALS: Fibroids during pregnancy are associated with worse obstetric outcomes. However, theres no recommendation to guide counseling. We aimed to assess the cost-effectiveness of (1) treating prevalent fibroids before pregnancy and (2) screening and treatment of fibroids against the outcomes of postpartum hemorrhage (PPH) and fetal malpresentation. METHODS/STUDY POPULATION: A decision tree model was used to compare (1) preconception myomectomy for prevalent fibroids, without treatment and (2) preconception myomectomy for prevalent cases and universal ultrasound screening with subsequent myomectomy for incident cases. Probabilities and costs, calculated from the U.S. healthcare sectors perspective, were derived from the literature. Effectiveness was measured in incident PPH or malpresentation cases per 1,000 in the population. The incremental cost-effectiveness ratio (ICER) was measured in incremental cost per case averted. One-way and probabilistic sensitivity analyses were conducted to identify influential parameters and assess the impact of parameter uncertainty. RESULTS/ANTICIPATED RESULTS: Treating known fibroids prior to pregnancy averted 65.7 PPH cases at the cost of $8,773,094 and 91.08 malpresentations at the cost of $8,163,315 (ICERs, $133,532 vs $89,628 per case averted, respectively). Universal fibroid screening with treatment of incident and prevalent cases averted 7.34 PPH cases at the cost of $3,725,619 and 2.7 malpresentations at the cost of $3,477,033 (ICERs, US$507,450 vs US$1,335,771 per case averted, respectively). Sensitivity analyses showed cost-effectiveness improved with decreased cost of myomectomy and increased proportion of prevalent and incident cases. DISCUSSION/SIGNIFICANCE: Treatment alone costs $133,532 per PPH averted and $89,628 per malpresentation averted. Likewise, screening with treatment costs $507,450 per PPH averted and $1,335,771 per malpresentation averted. Additionally, ICERs may decrease when focusing on populations where fibroid incidence and prevalence is higher, for example, among Black women.

OBJECTIVES/GOALS: Our aim is to understand the role bilirubin oxidation products play in the development of cerebral vasospasm in patients with subarachnoid hemorrhage. We aim to evaluate the time course of bilirubin, HO-1, and SOD1 in relation to the subsequent development of vasospasm in to establish predictors of vasospasm development. METHODS/STUDY POPULATION: Prospective cohort observational study involving collection of CSF samples of pts admitted to KU NeuroICU with SAH and placement of EVD. CSF will be extracted from the EVD of patients on the day of placement of the EVD, and then each subsequent day for a total of 10 days. Bilirubin concentration will be determined by means of spectrophotometry. HO-1 will be measured using a commercially available ELISA kit. Cu/Zn-Superoxide Dismutase will be measured using a commercially available ELISA kit. A review of patients chart will then be performed following discharge from hospital to determine if a diagnosis of vasospasm was made, details of the vasospasm (i.e. symptoms, severity), as well as to obtain demographic data and events occurring during patients admission that could confound statistical analysis. RESULTS/ANTICIPATED RESULTS: First: we will investigate the feasibility of collecting serial CSF samples and processing them for target analyte quantification. We predict that the protocol will yield quality data that will result in insight on the pathophysiology of cerebral vasospasm. Second: we will characterize the changes in target CSF bilirubin breakdown analytes over 10 days. From this we hypothesize that as bilirubin oxidation increases, the propensity for cerebral vasospasm will also increase. DISCUSSION/SIGNIFICANCE: If there is a clear correlation between formation of bilirubin and increase in HO-1, and SOD1, with the clinical signs of vasospasm, this could be used as a biomarker for not only identifying patients at risk for developing these complications but also a means to follow the effectiveness of potential therapies.

Public distrust in the US pandemic response has significantly hindered its effectiveness. In this community-based participatory research mixed-methods study, based on two datasets, we examined how distrust in COVID-19 vaccines relates to institutional distrust. We found that the Johnson & Johnson vaccine pause undermined trust in COVID-19 vaccines in general. Findings also suggest that vaccine distrust developed after participating in a study on COVID-19 testing. Increased distrust may be an unintended consequence of how healthcare and public health activities are presented and delivered, and research participation is structured. Both will continue without proactively addressing the root causes of distrust.

OBJECTIVES/GOALS: Heart failure (HF) is a clinical condition that notably affects the lives of patients in rural areas. The partnering of a rural satellite hospital with an urban academic medical center may provide geographically underrepresented populations with HF an opportunity to access controlled clinical trials (CCTs). METHODS/STUDY POPULATION: We report our experience in screening, consenting and enrolling subjects at the VCU Health Community Memorial Hospital (VCU-CMH) in rural South Hill, Virginia, that is part of the larger VCU Health network, with the lead institution being VCU Health Medical College of Virginia Hospitals (VCU-MCV), Richmond, VA. Subjects were enrolled in a clinical trial sponsored by the National Institutes of Health (ClinicalTrials.gov: NCT03797001) and assigned to treatment with an anti-inflammatory drug for HF or placebo. We used the electronic health record and remote guidance and oversight from the VCU-MCV resources using a closed-loop communication network to work with local resources at the facility to perform screening, consenting and enrollment. RESULTS/ANTICIPATED RESULTS: One hundred subjects with recently decompensated HF were screened between January 2019 and August 2021, of these 61 are enrolled to date: 52 (85 %) at VCU-MCV and 9 (15%) at VCU-CMH. Of the subjects enrolled at VCU-CMH, 33% were female, 77% Black, with a mean age of 5210 years. DISCUSSION/SIGNIFICANCE: The use of a combination of virtual/remote monitoring and guidance of local resources in this trial provides an opportunity for decentralization and access of CCTs for potential novel treatment of HF to underrepresented individuals from rural areas.

OBJECTIVES/GOALS: To develop the Adherence to Medications In Latinx adults with Depression and Anxiety (AMILDA) intervention using community engaged research principles, AMILDA will integrate culturally tailored messaging to improve depression and anxiety symptoms and adherence to antidepressant medications. METHODS/STUDY POPULATION: Bilingual steering committee members representing primary care and behavioral health professionals from 2 primary care clinics, and 1 lay community member met monthly for 1 year to develop the intervention. One clinic is an academic health center and the other is a federally qualified health center. Members identified, developed, and voted on the interventions components, therapeutic goals, and the mechanisms underlying its effectiveness that needed to be studied. To evaluate AMILDAs components, we conducted an observational study of health care providers (N=13) and Latinx adults with depression and/or anxiety (patients; N=26) from both clinics, and community pharmacists (N=9) from surrounding pharmacies to gather feedback. Based on their input, we revised the intervention. RESULTS/ANTICIPATED RESULTS: AMILDA consists of culturally tailored collaborative drug therapy management with a collaborative practice agreement between the physician and pharmacist. Patients recently started on an antidepressant receive language and culturally concordant motivational interviewing, teach back, and infographics; AMILDA is designed to improve symptoms, adherence, and health determinants. Most provider, pharmacist, and patient participants reported that AMILDA could be beneficial. Several participants indicated a lack of understanding about a US pharmacists scope of practice. Recommendations included ensuing language concordance, incorporating more statistics and scientific data, using images that are relatable, avoiding idioms and stereotypes, taking the time to build rapport, and being friendly. DISCUSSION/SIGNIFICANCE: AMILDA will be tested in a pilot effectiveness randomized controlled study to determine if it improves depression and anxiety symptoms and adherence to antidepressants among Latinx adults compared with enhanced usual care. The mechanisms to be assessed include self-efficacy, antidepressant knowledge, and personal health literacy.

Clinical trial participation among historically underrepresented populations remains low in large part due to mistrust of academic institutions and research investigators. Mistrust may be ever greater today given misinformation related to COVID-19. The Research Ambassador Program is an interactive educational workshop delivered by Promotoras de Salud/Community Health Workers and designed to both address common myths, fears, and concerns about research and encourage research participation among underrepresented populations. An evaluation conducted with 819 Latino and Black participants demonstrated a change in behavior and intention to participate in a clinical trial, with half of participants enrolling in a clinical trial research registry.

OBJECTIVES/GOALS: A qualitative study was performed to characterize experiences of Black and White women going through menopause, as well as identify barriers and facilitators for participating in a lifestyle program targeting weight management during menopause. This abstract includes data from Black women. Results from White women will be available by ACTS 2022. METHODS/STUDY POPULATION: Perimenopausal and postmenopausal Black women with a self-reported desire to lose or maintain weight during menopause participated in a total of six focus groups. Women were asked about their past experiences with diet, exercise, and weight management; their menopause experiences; as well as specific components and considerations for developing a lifestyle program for weight management. Thematic analysis was conducted on coded transcripts and four main themes emerged, each containing three to seven subthemes. RESULTS/ANTICIPATED RESULTS: Twenty-seven Black women (age 54±4 years, BMI 35.1±9.0 kg/m2) were enrolled. Overall, women felt unprepared for the changes they experienced during menopause and had difficulty maintaining or losing weight. While women were receptive to trying different diets and exercises, they wanted a diet that was flexible with their lifestyle and exercises that considered their existing health status. Women were also interested in learning about menopause alongside other women, stating that medical professionals did not provide them with adequate information or help. Social support, accountability, and seeing results were perceived critical to achieve long-lasting behavioral change. DISCUSSION/SIGNIFICANCE: Women were interested in receiving menopause information and improving their overall health as part of a lifestyle program during menopause. Associating with other women affected by menopause will allow for the creation of more sustainable lifestyle programs during menopause.
