This paper considers how education can address two persistent problems concerning directors of smaller companies. Virtually anyone can be a company director, even though this is a complex role with significant impacts. Director disqualification is the main filter, to instil market morality and improve standards among directors. Yet disqualification lacks any rehabilitative element, and it is doubtful whether it is effective in raising standards, given persistent problems, including phoenix companies and rogue traders. We consider whether education might usefully improve the effectiveness of disqualification through a rehabilitative element. Rehabilitative approaches can also potentially help other directors, who have failed, to try again. We also consider the potential of an optional education programme for directors who have experienced company failures and have not been disqualified.
Drawing upon examples of education being used to raise standards in other contexts, as well as educational theories in relation to adult learners, the paper shows how education might: (1) strengthen the disqualification system; and (2) support directors who are outside the disqualification system to start again after a failure. Both aspects are important to market integrity as well as economic opportunity.
Objectives/Goals: Research supports the use of music to improve the care and well-being of adults living with dementia; however, the practice and implementation of music in elder care communities is not regulated. The goal of this qualitative study was to survey elder care communities in Northeast Kansas to determine the use of music with people living with dementia. Methods/Study Population: We interviewed staff (n = 10) at five elder care communities in the Kansas City Metro area and observed musical activities and artifacts in shared living spaces within each community. Interview questions included details of the frequency and purpose of using music, who determined which music to use, and any effects, positive or negative, the interviewee believed to be associated with the use of music. Musical events, visiting musicians or music therapists leading group sing-alongs were observed at two communities, and music-related activities led by staff were observed at two others. Results/Anticipated Results: Music was used in some way at each of the five communities. Each location had recorded music available to residents in the shared living spaces, and most had a piano in the main lounge area. During the sing-along and music-related activities, residents were observed singing along to songs from memory, engaging with one another and the group leader and smiling. Staff employed by each community varied in their level of musical training and experience, from none to a full-time music therapist in residence. Staff interviewed said they believed music was helpful to aid memory recall, reduce anxiety, and to engage interest. Interestingly, a music therapist at one site also described how music during mealtimes created too much of a distraction for residents and interfered with dietary care. Discussion/Significance of Impact: It is clear from both the staff interviews and direct observations of musical activities that music is important to consider for people living with dementia in care communities. Guidelines for implementation and minimum standards would be helpful to ensure all care community residents can experience benefits highlighted by staff in this study.
One of the tendencies among scribes who transmitted the corpus Philonicum was to divide treatises into smaller units. This article argues that Philo’s De gigantibus and Quod Deus sit immutabilis were originally a single treatise that scribes split in an effort to create thematic unities for each half. Two lines of evidence support this conclusion. There is significant evidence that the two treatises circulated as a single work in antiquity. The most important evidence lies in the titles. Eusebius knew a compound title for a single work and the eighth-century compilers of the Sacra parallela attributed fragments from Quod Deus sit immutabilis to De gigantibus. The second line of evidence is internal. De gigantibus is noticeably shorter than any other treatise in the Allegorical Commentary with the exception of De sobrietate that may be incomplete. More importantly, the work concludes with an internal transitional phrase that introduces the citation that opens Quod Deus sit immutabilis. While Philo creates a bridge between treatises, this is an internal transition marker. For these reasons, we should discontinue following the scribal tradition and reunite the two halves of Philo’s treatise.
Objectives/Goals: Now in its 10th year, Research Jam, Indiana CTSI’s Patient Engagement Core, has proven to be an effective approach to patient engagement, foregoing generalized CABs for study-specific groups, personally invested in the research. Here we share our methods to benefit CTSAs seeking deeper engagement. Methods/Study Population: Research Jam is unique from patient engagement efforts in other CTSAs in almost every aspect. The composition and background of our team, the methodology to our practice and often our outcomes. This poster will use 10 years of projects, publications, and participant evaluations to explore our approach both quantitatively and qualitatively to see how it has contributed to the Indiana CTSI’s commitment to community engagement. Results/Anticipated Results: We will present quantitative data from 10 years of participant evaluations illustrating that Research Jams are received positively by those that attend, and qualitative analysis of the evaluations around themes of feeling heard, valued, and integral in research. By finding themes in evaluations across 10 years of studies, with different topics, different population types, and different investigators, we can speculate on what aspects of our approach appeal to the community, contribute to their positivity toward research and researchers, and could be reproducible in other CTSAs. Discussion/Significance of Impact: We use “blueprint” instead of “toolkit” when describing our process, as we hope others can see this not as a tool to fix a problem, but a plan to be iterated on in agreement with the community that will benefit from it. The relationships researchers need to build with communities are not cookie cutter neighborhoods, but rich, colorful and vibrant ones.
We determined whether Dietary Species Richness (DSR) i) can be robustly measured using four-day food intake data, ii) is dependent on sociodemographic characteristics, and iii) is associated with diet quality.
Design:
The National Diet and Nutrition Survey (NDNS) nutrient databank 2018–2019 was expanded to include FoodEx2 food classifications, ingredients, the number and identity of unique species, Nutrient Rich Food 8.3 (NRF8.3) Index scores, and greenhouse gas (GHG) emissions. Four-day food intake data and sociodemographic variables were used to calculate diet quality and DSR on the food and diet level.
Setting:
The United Kingdom (UK).
Participants:
Participants from NDNS 9 to 11 (2016-2019).
Results:
Composite dishes had the highest DSR (median 8 [Q1=4, Q3=12]), followed by seasoning, sauces, and condiments (median 7, [Q1=4, Q3 =10]) and, grains and grain-based products (median 5, [Q1=2, Q3=7]). Median DSR over four days was 49 [Q1=43, Q3=56; range 14 - 92], with the first two days achieving 80% of DSR measured over four days. DSR was significantly higher in those who were younger, those with a higher household income, or those with a lower level of deprivation (all p<0.001). Higher DSR was associated with a small but significant improvement in nutritional quality (p<0.001). Also, adherence to dietary guidelines such as fibre, fruits and vegetables, and fish was associated with significantly higher DSR (all p<0.001).
Conclusions:
We successfully established DSR based on four-day food intake data. We also identified opportunities to improve DSR by increasing the consumption of fruits, vegetables, fibre, and fish.
Objectives/Goals: The Clinical Research Education in Genome Science (CREiGS) program was developed to address the need for faculty and trainees conducting biomedical research to gain foundational training in genome science and accelerate the clinical adoption of genomic medicine. CREiGS, funded by NHGRI, offers comprehensive training in genomic analysis and statistical computing. Methods/Study Population: CREiGS targets a diverse pool of medical/doctoral students, postdocs, and faculty from academic institutions nationwide. The hybrid program included an 11-week online phase and a 3-day in-person phase, focusing on genomic science, statistical analysis and R programming, rigor and reproducibility, and engaging diverse populations in genomics research. Advanced special topics lectures included: decision analysis for genomics research, bioethical engagement of indigenous communities in genomics research, elucidating gene networks for advancing human health, etc. Strategies for recruiting diverse participants and ensuring an inclusive learning environment were informed by the Diversity Recruitment External Advisory Board. Participants’ skills were evaluated via pre- and post-course surveys. Results/Anticipated Results: Of 187 participants over 5 cohorts, 68.4% were female and 47.0% from underrepresented groups. The cohort spanned career stages, with 35.3% students, 34.2% postdocs, and 30.4% faculty, most of whom were at the junior level. Competency evaluations showed improvements in all core competencies of the course: (1) independently carrying out small-scale research improvements, (2) confidence collaborating with statisticians, bioinformaticians, and other genome science experts, (3) applying appropriate statistical methods for the analysis of genetics and genomics data, (4) accurately interpreting findings from genome research studies, (5) critiquing the internal/external validity of genome research studies, and (6) effectively engaging diverse populations and community stakeholders. Discussion/Significance of Impact: CREiGS successfully provided inclusive, high-quality, genomic and statistical training, to diverse scientists enhancing their research capacity and methodologic competency. Findings from longer term evaluations examining the contribution of CREiGS to participants’ genome science-related scholarly productivity are forthcoming.
Objectives/Goals: Some children with asthma benefit from care from asthma specialists: allergist/immunologists or pulmonologists. However, a limited supply of specialists poses access problems for some children. Our objective was to describe the state of specialist care for pediatric asthma in Maine. Methods/Study Population: Using Maine all-payer claims data for April 2018–April 2021, we identified children with asthma meeting criteria for subspecialist referral based on NIH Expert Panel Report criteria. We determined which of these children had encounters with an allergist-immunologist or pediatric pulmonologist during the study period and performed logistic regressions to determine what demographic traits were associated with receipt of care. Results/Anticipated Results: Among children meeting criteria for specialists referral, 33% had an encounter with an asthma specialist. Specialist encounters were associated with younger age (p<0.001) and male sex (p = 0.003). Encounters were negatively associated with Medicaid insurance (versus commercial, p<0.001) and living in more rural areas (RUCA codes 4–10, p<0.001), lower childhood opportunity index (high or less, <0.001), and longer travel time to pediatric asthma specialists in Maine (<0.001). Discussion/Significance of Impact: Specialist care for children with complex or severe asthma is an evidence-based practice that is not equally accessible to all children in Maine. This may restrict their access to specific asthma therapies such as allergic desensitization and monoclonal antibodies.
Objectives/Goals: Understanding cognitive habits and values of individuals or groups, and providing tools to apply them to collaborative, interdisciplinary endeavors to better communicate between different industries, functions, and cultures. Methods/Study Population: Using literary research to establish groupings of common core values in interpersonal communications, applying established 5 patterns of “thought languages” to scale to group communications. Accepted psychological personality inventories for individuals will overlay into cognitive values, primarily using the current big five OCEAN model. Demonstrating these values to find common goals among interdisciplinary collaborations can identify prospective members, cultural differences in industry, patient communication, and public messaging in STEM. Integrating these tools into research groups to establish more efficacious communication between teams, governing bodies, and patient communication can be sampled via pre and post research surveys of feeling understood. Results/Anticipated Results: The results of feeling understood by various parties in collaborative research would be a measure of not just effective expressed communication, but received communication. Feeling understood is a current metric of communication that is correlated with satisfaction, trust, and interdependence. All of these results are integral to the successful operations of collaborative projects. Demonstrating a positive correlation between applying the 5 thought languages and better-surveyed outcomes of understanding will guide the effectiveness of this as a future collaborative tool for translational sciences. Discussion/Significance of Impact: The significance of effective communication based on positive reception will foster future collaborations. Encouraging familiarity between differing individuals, groups, and industries, even between subjects and researchers, patients and healthcare. More satisfaction, more trust, and more interdependence will propagate between these groups.
Objectives/Goals: The impact of the program on alumni students was measured in a 2023 survey, which assessed key factors and student perspectives on motivation to apply/remain in the program, their engagement activities, how they used the skills acquired in RAP upon graduating, and if they were currently serving in a health profession and/or clinical research. Methods/Study Population: Survey questions were based upon specific components of CTSI-RAP that make it unique. Covered topics related to motivation for participation, meaningful experiences, program effectiveness, future use of RAP knowledge/training, and current career roles in the health professions and/or clinical research. The survey was built and analyzed in REDCap and deployed May–July 2023. The study received exempt certification from the IRB. The survey was sent to 123 alumni from the 2013 to 2021 cohorts. Bounced e-mails were followed up on and two reminder e-mails were sent to initial non-responders. Identifiable demographic information was separated from program evaluation questions for analysis. A subanalysis was performed to determine program impact on students who identified as underserved or disadvantaged. Results/Anticipated Results: Respondents included 82/123 (66.7%) alumni. The survey took approximately 15 minutes. Most of the students 64/82 (78.0%) had 1 year or less research experience. The top three motivating factors for joining the RAP program were gaining clinical research experience, exposure to healthcare settings, and interest in pursuing a healthcare related career. Most alumni rated the overall effectiveness of the RAP program as very or somewhat valuable and the majority felt that the program ranked high or very high among their undergraduate experiences. The program was very influential or influential in defining their long-term plans and goals. Just under half felt that their career aspirations were changed or influenced by the program, which was especially true for those who identified as underserved/disadvantaged. Discussion/Significance of Impact: CTSI-RAP alumni highly value their experience in the program. They have benefitted professionally and are motivated to keep their connection to the program alive. With a decade of clinical research excellence and programming, CTSI-RAP’s impact is well established as a proven model benefiting both students and the clinical research infrastructure.
Objectives/Goals: This project will enrich our understanding of basal breast carcinogenesis, highlighting the distinct biological differences in breast cancer risk between non-Hispanic Black (NHB) or non-Hispanic White (NHW) women, but also has the potential to provide real-world solutions thereby contributing to reducing health disparities in breast cancer outcomes Methods/Study Population: In the biological investigation, I am utilizing a unique cohort of normal breast tissues from Mayo Clinic patients who underwent breast reduction surgery that have self-identified as NHB or NHW premenopausal women. From these tissues, we are able to subculture human mammary epithelial cells, which we will use for our consequent experiments. For the qualitative study, I aim to recruit up to 40–50 eligible NHB women identified at increased risk for breast cancer and conduct semi-structured qualitative interviews informed by the National Institute on Minority Health and Health Disparities Research Framework. Results/Anticipated Results: Gene expression profiling on our cohort of 15 NHB and 40 NHW premenopausal women identified a gene expression signature in NHB women indicative of elevated Hedgehog signaling, a key factor in triple-negative breast cancer (TNBC) development and progression. I hypothesize that persistent activation of Hedgehog signaling within NHB women instigates the proliferation and transformation of basal stem cells within the breast, thus fueling TNBC development. Understanding the perceptions and experiences of NHB women that are identified as being at an increased risk for BC will aid in the identification of barriers and facilitators to their risk reduction care and in turn provide implementation strategies that could contribute to alleviating the racial disparity seen in TNBC morbidity, mortality, and preventative care. Discussion/Significance of Impact: The significance of this project lies in its dual approach, uncovering basal breast cancer mechanisms in a high-risk group using normal breast tissue and evaluating the perspectives from NHB women to enhance the practical relevance of our findings.
Objectives/Goals: Access to accurate public health information is an essential component to ensuring health equity. We launched our social media channels on Instagram, Facebook, and TikTok to highlight, engage with, and bring culturally tailored and language appropriate health and research information to our target communities. Methods/Study Population: Monitoring engagement patterns with our content on each platform influenced the development of a range of innovative campaigns in both English and Spanish that were informed by our core values of inclusivity, trust-building, ongoing bidirectional communication, and co-creation. These three platforms were chosen to ensure reach and engagement with the different demographics within our target populations. The campaigns included those that provided relevant and accurate health information, highlighted the diversity of our team, uplifted our community partners, and gave voice to our community members. This content included health-related infographics, mini-documentary reels, video essays, interviews, and photos. Results/Anticipated Results: We assessed effectiveness, reach, and engagement based on the robustness of the analytics for each platform. Facebook content, the majority of which is in Spanish, appealed more to older, Latino community members. TikTok content appealed more to younger (under 35), primarily English-speaking community members, while Instagram appealed more to organizational partners and community health workers. A 2023 trendline analysis of average monthly Instagram content reach and interactions indicated a moderate-to-strong relationship between our tailored content and audience engagement. Storytelling techniques consistently outperformed other content types across platforms, and community partner collaboration drastically enhanced our visibility, reach, and further validated our approach. Discussion/Significance of Impact: Social media has become increasingly central to bidirectional information dissemination. Implementing tailored strategies and leveraging storytelling techniques is an effective means of engaging diverse audiences, enhancing public health communication, and building and maintaining trust by providing accurate, accessible information.
Objectives/Goals: This study aims to first understand the expression of the L-type amino acid transporter, Slc7a5, in demyelinated plaques in postmortem multiple sclerosis (MS) CNS tissue. It also seeks to understand the effect of a novel inhibitor of Slc7a5 on remyelination in mice with experimental autoimmune encephalomyelitis. Methods/Study Population: Using single-cell RNA sequencing (scRNA-seq), we will examine the expression of Slc7a5 in demyelinated plaques in postmortem CNS tissue of patients with MS compared to non-lesioned regions (n = 3/group). Using visually evoked potential (VEP) on mice with experimental autoimmune encephalomyelitis (EAE), we will determine the ability of the Slc7a5 allosteric inhibitor OKY-034 to promote remyelination compared to EAE-only controls (n = 10/group). Lastly, we will use spatial transcriptomics with scRNA-seq to map transcriptional activity within different populations of cells to determine how OKY-034 changes gene expression in specific cell types compared to EAE-only controls (n = 3/group). Results/Anticipated Results: A conditional knockout of Slc7a5 showed that microglial activation and oligodendrocyte differentiation were affected in demyelinated lesions. This suggests that it plays a role in numerous cell types in active demyelinated plaques, which is what we expect to find from our scRNA-seq data in post-mortem CNS tissue of patients with MS. Measuring VEP is a noninvasive way to measure remyelination in both clinical and research settings. OKY-034 increases oligodendrocyte differentiation suggesting remyelination, so we expect that administration of OKY-034 in mice with EAE will lead to restored VEP compared to control and EAE-only mice. Lastly, because OKY-034 reduces inflammation, we expect to see a decrease in gene expression for genes involved in an immune response. Discussion/Significance of Impact: Completion of this study will lead to understanding what the effect the allosteric Slc7a5 inhibitor OKY-034 has on remyelination and whether it may serve as a novel therapeutic drug that can be administered orally for the treatment of MS. This could lead to its further development as a treatment for progressive MS.
Objectives/Goals: To develop a user-friendly tool to simplify the Trillium Drug Program (TDP) application process, addressing barriers for pre-exposure prophylaxis (PrEP) users aged 25 to 64 years. This project may also serve as a scalable model for improving accessibility across other service delivery programs. Methods/Study Population: This study uses the Translational Research Framework to create and refine an online TDP guide. Participants include Ontario residents aged 23 to 64 years. Challenges are identified in the “Understand” phase, while user-driven feedback in the “Act” phase iteratively enhances the tool. Virtual prototyping interviews via Zoom will assess user experience, and error rates will be evaluated by comparing tool suggestions with verified mock scenarios. Twenty participants will test the tool in two iterations: Version 1 from January to February 2025, and Version 2 based on feedback from February to March 2025. Results/Anticipated Results: It is anticipated that participants will encounter fewer barriers to completing the TDP application when using the tool. We expect to see an improvement in user experience by simplifying complex procedures and guiding participants through mock applications with generated scenarios. Data collected from user feedback will highlight specific elements of the tool that require enhancement. Ultimately, we anticipate an increase in successful TDP applications among participants and improvements in accessibility and efficiency of the application process for PrEP users aged 23 to 64 years in Ontario. Discussion/Significance of Impact: The developed tool aims to reduce financial barriers to PrEP access by facilitating successful enrolment in the TDP. The project’s broader impact includes improving health outcomes for underserved communities and contributing to equitable healthcare service delivery.
Objectives/Goals: Conduct an evaluation of the Clinical Research Support Center (CRSC) model using a structured methodology, leverage insights to drive continuous improvement and evolution, and broadly disseminate outcomes to promote knowledge sharing and best practices for similar translational science initiatives. Methods/Study Population: We will utilize a structured case study approach, including adapting a translational science case study evaluation approach to assess impact as well as support practices, barriers, and facilitators that influence research translation. We will collect data from diverse sources. Primary data will come from structured interviews with stakeholders and a survey of a random sample of faculty and research staff. Secondary data includes grant applications, reports, and publications; public stories/media related to research supported by CRSC; scientific publications; and organizational documents. Results/Anticipated Results: The case study will identify the CRSC model’s impact on the research enterprise. Findings will articulate the specific strategies and practices the CRSC implemented to support clinical research; key factors, people, and resources that helped develop, improve, and promote CRSC services; significant milestones in evolution of the CRSC; and specific ways in which support services impact clinical research infrastructure and outcomes. The findings will highlight both strengths and areas for improvement. Early results show historical challenges with operational silos and resource limitations. Findings suggest CRSC facilitators include a team science approach with institutional support. Discussion/Significance of Impact: This case study will provide insights related to benefits, challenges, and facilitators of a translational science support model. Insights will guide the CRSC’s evolution and be broadly disseminated to promote knowledge sharing and best practices for future translational science applications.
Objectives/Goals: The Wake Forest Clinical and Translational Science Institute (CTSI) has integrated academic goals of T0-T4 translation, scholarship, and education into our Academic Learning Health System (aLHS) framework. Our Translation Research Academy (TRA) provides rigorous training for outstanding and diverse K12 and early-career faculty to develop LHS core competencies. Methods/Study Population: The TRA Forum is the main vehicle for delivering an aLHS-oriented curriculum. Currently, the program includes six K12 scholars and 18 other early-career research faculty with facilitated access to CTSI resources. The TRA Forum is a 2-year seminar series that meets twice a month to discuss topics relevant to the aLHS, leadership, and career development. Inclusion of first- and second-year scholars facilitates peer mentorship, allowing Year 2 scholars to share insights with new scholars. Forum sessions are developed around adult learning theory: Each participant is asked to contribute their experience to discussions, and sessions focus on real-world examples. Results/Anticipated Results: Scholar and faculty commitment is very high. For the first 30 min., scholars present their work in small groups. This extends the range of disciplines exposed (64% of TRA graduates found this very helpful) and promotes translational traits of boundary crosser, team player, and systems thinker. Participants view the TRA as an opportunity to form internal peer networks, promote peer mentoring, and establish new collaborations. The remaining 60 minutes are used for education. Sessions include nominated topics and those providing a solid foundation in core aLHS competencies and characteristics of translational scientists. Educational sessions (97%) were rated as helpful or very helpful. Discussion/Significance of Impact: TRA scholars receive rigorous training in a highly supportive environment to produce aLHS researchers with skills to transcend boundaries, innovate systems, create new knowledge, and rigorously evaluate results.
Objectives/Goals: This study examines prevalence of complete sample size justifications in publications in the top five clinical neurology journals. Secondary goals include comparing study designs and clinical populations to explore whether some may be more likely to include inadequate sample size considerations. Methods/Study Population: Recent studies (n = 125) in Lancet Neurology, Alzheimer’s and Dementia, JAMA Neurology, Acta Neuropathology, and Brain will be evaluated. For each journal, the 25 most recent empirical articles between 2022 and 2023 will be examined for their inclusion of a justification and reproducible sample size calculation. Inclusion of components of an ideal sample size justification will be evaluated: effect size to be detected (standardized or unstandardized), alpha, power, and from where values were derived. Prevalence and completeness will be compared among study designs, clinical populations, and with regard to journal reporting requirements. Results/Anticipated Results: At the pilot review stage, 17 of 25 included studies had any kind of sample size justification, and only 3 studies had enough information to reproduce their sample size calculations. Retrospective studies included a sample size justification more frequently (81.8% vs. 57.1%), but prospective studies had more complete sample size justifications, when present. We hypothesize that sample size calculations will be more complete in reports of clinical trials and prospective cohort studies, compared to retrospective and cross-sectional designs. Based on our previous research, we do not expect that journal reporting requirements will affect completeness of sample size justifications. Discussion/Significance of Impact: Translational decision-making is informed in part by the robustness of current research. Transparency of sample size considerations in publications can contribute to the formation of less biased opinions of translational readiness and, subsequently, more efficient and effective translation.
Objectives/Goals: The aging population faces unique health issues, many of which are exacerbated by aging-associated immune function decline. However, the driving mechanisms behind this decline are poorly understood. We use a mouse model to study the relationship between extracellular matrix (ECM) stiffness and cell mobility within the lymph node (LN) as one potential driving mechanism. Methods/Study Population: We will collect LN from young (6 weeks old) mice and acquire LN from aged (11 month old) mice from a collaborator. We will section LN for ex vivo analysis, including quantification and localization of collagen I using immunofluorescent staining, analysis of microrheological properties using multiparticle tracking (MPT) with PEGylated fluorescent nanoparticles, and migration assays to track the movement of B and T cells. Results/Anticipated Results: We hypothesize a positive correlation between collagen deposits and stiffness within murine LNs due to known mechanisms underlying age-related fibrosis. We also hypothesize that areas of increased stiffness (as revealed by MPT) will exhibit decreased cell migration due to physical hindrance to B and T cell mobilization. Furthermore, we hypothesize that aged murine LN will exhibit a significant increase in stiffness and resultant decreased cell mobility when compared to young murine LN, particularly in areas with increased collagen localization. Discussion/Significance of Impact: These studies will elucidate structure–function relationships driving age-associated LN fibrosis and stiffness, and the resultant impedance to cell migration, thus clarifying some of the potential driving mechanisms behind immune aging and providing data capable of informing the development of relevant models and interventions.
Objectives/Goals: Despite the documented link between ultraviolet (UV) exposure and skin cancer, the potential protective role of pigmentation in preventing skin carcinogenesis is not fully understood. This project will test the hypothesis that individuals with light skin tones are more susceptible to skin cancer due to a higher accumulation of somatic mutations from UV exposure. Methods/Study Population: Skin biopsies were collected from various anatomical sites of seven donors aged 70 to 80 years with dark skin tones and used to generate clones of normal skin cells. The clones were then subjected to whole-exome and RNA sequencing. We developed a workflow that allows us to accurately detect somatic mutations in clonal expansions of individual cells with high specificity and sensitivity. For comparison, we also analyzed mutations in skin cells obtained from individuals with light skin tones, who served as our control group. In the future, we plan to employ admixture analysis to clarify the impact of race on somatic mutations by examining ancestral genetic contributions. Results/Anticipated Results: Our preliminary analysis of the existing data supports our hypothesis. The average mutation burden in individuals with light skin tone was found to be 3.778 Mut/Mb, whereas in those with dark skin tones, was only 0.818 Mut/Mb. These findings align with the prevailing hypothesis that melanin acts as a protective factor against skin cancer, as it appears to reduce the mutagenic effects of UV radiation. This suggests that individuals with darker skin may have a lower cumulative mutational load, potentially contributing to their reduced risk of developing skin cancers such as melanoma. Similarly, our results showed variations in mutational burdens across different anatomical sites, which seemed to be influenced by differing levels of UV exposure, with the highest burdens observed in areas with the greatest exposure. Discussion/Significance of Impact: Understanding how skin cancer operates in darker-skinned individuals is imperative for tailoring effective screening and targeted therapies to meet their specific needs. In the long run, elucidating the mechanisms underlying skin cancer development in this demographic will help refine screening protocols and prevention recommendations.
Objectives/Goals: Audience will understand the engage for equity CBPR conceptual framework used to develop our partnership survey. Audience will better understand our survey design and administration process. Audience will understand our initial experiences, community advisory board member responses, and how the process influenced our engagement efforts. Methods/Study Population: The objective of this assessment is to understand how our community partners perceive our engagement efforts. The questionnaire is based on the 12 constructs of the CBPR engage for equity model. We plan on annually assessing impact and refining engagement approaches in response to community partners’ perspectives. Community Advisory Board members and other partners will complete an online survey and participate in a subsequent discussion and planning session about the responses. We anticipate evaluating approximately 400 community partners who collaborate with the Wright Regional Clinical and Translational Science Awards between 2023 and 2030 with a RedCAP survey and discussion. The instrument uses validated questions from a range of engagement instruments to assess context, partnership structure, processes, outputs, and outcomes. Results/Anticipated Results: We hypothesize that both the survey and subsequent discussion about how respondents reacted to answering the questions will improve our ability to track and adapt our community engagement efforts. Discussion/Significance of Impact: Our annual survey is not project specific and using it longitudinally will inform our engagement process to research that aligns with community needs. We anticipate this will help us to guide our research agenda to align with community needs and define impact of our university–community partnership.
