Abstract Introduction. Understanding the unique social and environmental contexts of communities is essential for designing effective, locally tailored cancer intervention strategies. This study aimed to identify key findings from a comprehensive, multifaceted, cancer-focused needs assessment conducted across three U.S. regions, offering insights into the social, behavioral, and structural barriers that hinder cancer prevention and control, and informing regionally tailored interventions. Methods. This study focused on adult residents within the Mayo Clinic Comprehensive Cancer Center catchment areas, covering 75 counties across Arizona, Florida, and the Midwest (Minnesota, Wisconsin, and Iowa). Data was collected through collaborations with the University of Florida and Mayo Clinic Survey Research Centers, and the “Boots on the Ground" approach involving community health workers. Methods included phone calls, online submissions, and community outreach for an anonymous survey. Validated measures assessed healthcare access, lifestyle, social networks, neighborhood conditions, and discrimination. Descriptive analyses were conducted using valid responses. Non-responses and selections of “Prefer not to answer” were excluded from percentage calculations to ensure interpretive accuracy. Results. Involving 2,681 respondents, the data reveal consistent yet regionally nuanced barriers to cancer prevention. Health insurance coverage was relatively high across all regions—77.6% in Arizona, 85.5% in Florida, and 89.2% in the Midwest. Despite this, access to care remained limited. In Arizona, 22% of respondents could not afford to see a regular doctor, and 41.3% reported delays due to work or transportation. In Florida, 26.6% reported financial barriers to primary care, and nearly half (49.7%) experienced delays in receiving care. The Midwest showed fewer neighborhood safety concerns but still faced high rates of care delays (46.7%) and housing-related issues (42.6%). Neighborhood-level challenges were common. Housing-related problems were reported by 42.9% of respondents in Arizona, 54% in Florida, and 42.6% in the Midwest. Concerns about drug use were highest in Arizona (40%) but present across all regions. Health behavior risks were also widespread: 72–79% of respondents reported sleep difficulties, and many reported low physical activity, suboptimal sun protection, and routine alcohol use. Psychosocial stressors were prominent, with 51–65% of respondents reporting experiences of disrespect and 42–66% feeling unheard by healthcare providers. Conclusions. Despite relatively high rates of insurance coverage, communities across all regions face persistent challenges in accessing timely, affordable, and respectful healthcare. Coupled with neighborhood instability, adverse health behaviors, and psychosocial stressors, these barriers highlight the urgent need for regionally tailored strategies that strengthen both cancer prevention and care. Addressing these interconnected challenges at the community level is essential for promoting more equitable cancer outcomes. Citation Format: Tingyu Zou, Monica L.

Abstract C138: Influence of demographic factors and knowledge on prostate cancer screening attitude and research participation among Black men
Abstract Introduction: The disproportionate prostate cancer (CaP) burden, which includes high mortality rates, is significantly attributed to the characteristics of the social determinants of the health status of the Black Male population. Designing targeted interventions to address poor health outcomes through a collaborative population-based approach could reduce CaP health disparities. The Community Living Lab (CoLLab) Learning Health System was developed to address ethnically sensitive, targeted approaches that will eliminate CaP health disparities among Black Men. This study assessed demographic factors and Knowledge on prostate cancer screening attitudes and research participation among black men. Method: The collab project employed a social ecological model to design intervention to address barriers to CaP screening and participation in clinical trials. A validated, pretested questionnaire was used to collect information on demographics, CaP knowledge, attitudes, testing, and a history of participation in research and clinical trials. Baseline data were collected from 3 American Legion posts (ALPs). The association between variables was evaluated using the Chi-square test. Results: Participants between 60-69 years were 28.38%, and those aged 40-49 were 12.16%. Most are US-born Black (89.8%), with others identifying as African-born Black (6.76%) and Caribbean-born Black (1.35%). Approximately 43.24% were retired, and 36.49% were working full-time. CaP knowledge was high in 43.9%, moderate in 46.6%, and low in 9.5%. Only 45% of the participants have undergone Prostate-Specific Antigen test, and 24.6% have had a Digital Rectal Examination. Reported past clinical trials and research participation were very low (9.38%). Participants with higher knowledge levels had higher information scores (p < .0001), favored various research settings (p = 0.0008), had favorable attitudes towards CaP testing (p < .0001), and were more likely to participate in research (p = 0.0117). Work status was found to impact CaP Knowledge (p = 0.0117). Participants with stronger beliefs about prostate cancer may have different attitudes toward testing (p = 0.0444). Age did not impact attitudes toward CaP testing (p = 0.4298). Conclusion: The knowledge of CaP was found to impact the attitudes, testing, and disposition of the participants towards research. The baseline data generated from the clinical study will curate insightful evidence that will create innovative approaches to prostate cancer education among males in Black communities.

Abstract B030: Health literacy and digital engagement across US Regions: Insights from the mayo clinic catchment areas
Abstract Introduction: Understanding how communities access and engage with health information is essential for effective health communication. Health literacy—the ability to read, understand, and use healthcare information—plays a crucial role in making informed health decisions. With the rise of digital technologies, internet access and online engagement have become key tools for obtaining health information. However, variations in health literacy and digital engagement can limit some populations' ability to fully access these resources. This study examined health literacy, cancer information-seeking behaviors, internet access, and digital engagement among adults in the Mayo Clinic Comprehensive Cancer Center catchment areas to inform more effective and region-specific health communication strategies. Methods: This study focused on adult residents within the Mayo Clinic Comprehensive Cancer Center catchment areas, covering 75 counties across Arizona, Florida, and the Midwest (Minnesota, Wisconsin, and Iowa). Data were collected through partnerships with the University of Florida and Mayo Clinic Survey Research Centers, and the "Boots on the Ground" approach involving community health workers. Methods included phone calls, online submissions, and community outreach for an anonymous survey. Validated measures assessed health literacy, information access, and digital engagement. Descriptive analyses were performed using valid responses, excluding non-responses and "Prefer not to answer" options to ensure interpretive accuracy. Results: Data from 2,681 respondents highlighted consistent barriers to cancer prevention with regional differences. In Arizona, 42.6% of respondents need help reading medical materials, but only 3.1% reported lacking confidence in obtaining cancer-related information. In contrast, 63.1% felt very or completely confident in accessing cancer advice. The primary sources of health information were doctors (17.6%), internet searches (11.4%), and family (9.8%). In Florida, 38.4% need assistance, but only 2.7% lack confidence, and 68.2% feel very or completely confident. Doctors (18%) and internet searches (13.1%) were top sources. In the Midwest, 38.5% struggle with medical documents, and 3.1% reported lacking confidence, while 66.4% felt very or completely confident. Internet access is widespread across all regions, with smartphones being the dominant device. Daily internet use for communication, browsing, and engagement with health apps and social networks remains high. Conclusion: Although many respondents face challenges with reading health-related materials, most report high confidence in obtaining cancer information, suggesting a gap between functional health literacy and perceived ability to access information. The widespread use of mobile devices and near-universal internet access offers a valuable opportunity to enhance health communication through digital tools. These findings emphasize the importance of tailored digital outreach to bridge literacy gaps and ensure underserved populations can access reliable health information.

Plasma Phosphorylated Tau 217 to Identify Preclinical Alzheimer Disease
Importance Advances in Alzheimer disease (AD) have shifted research focus to earlier disease stages, necessitating more scalable approaches to identify cognitively unimpaired individuals with amyloid β (Aβ) pathology. Objective To assess the utility of plasma phosphorylated tau 217 (p-tau217) for classifying Aβ status in cognitively unimpaired individuals, both as a stand-alone test and in a 2-step approach where positive plasma results were confirmed using a second modality (Aβ positron emission tomography [PET] or cerebrospinal fluid [CSF]). Design, Setting, and Participants This cross-sectional cohort study used data collected between June 2009 and March 2024. We included 2916 cognitively unimpaired participants from 12 international independent observational cohorts in the US, Europe, Australia, and Canada with available plasma p-tau217 levels and CSF or PET Aβ biomarkers. Performance comparisons between mass spectrometry and immunoassay-based p-tau217 measurements were also performed (n = 964). Exposures Plasma p-tau217 levels measured by immunoassay. Main Outcome and Measures Aβ status, determined by CSF or Aβ PET biomarkers. Results Participants had a mean (SD) age of 66.9 (9.9) years; 971 (33.3%) were Aβ positive by either CSF or PET, 1667 (57.2%) were women, and 1108 (38.1%) carried at least 1 APOE ε4 allele. As a stand-alone test, plasma p-tau217 achieved a positive predictive value (PPV) of 79% (95% CI, 74-84) and an overall accuracy of 81% (95% CI, 80-82). In a 2-step workflow, the PPV and accuracy significantly increased to 91% (95% CI, 86-95). While this approach required screening of 677 individuals with plasma p-tau217 to identify 100 Aβ-positive individuals, compared to 536 participants when using PET alone, it reduced the need for PET testing to 124. Immunoassays demonstrated comparable PPVs to mass spectrometry (80% [95% CI, 74-86] vs 85% [95% CI, 81-90]; P = .12) but significantly lower overall accuracy (82% [95% CI, 79-84]% vs 88 [95% CI, 86-90]; P &lt; .001) and true Aβ-positive detection rate (49% [95% CI, 43-55] vs 69% [95% CI, 64-75]; P &lt; .001). Conclusions and Relevance The findings highlight the potential of plasma p-tau217 as a stand-alone test—or when used in a sequential 2-step approach alongside PET or CSF testing—as a cost-effective, scalable, and minimally burdensome strategy for identifying preclinical AD. Tailored screening workflows that incorporate p-tau217 can improve efficiency in participant selection for preclinical AD trials and, in the future, help guide access to disease-modifying treatments.
A Cross‐Sectional Analysis of Social Determinants of Health in Bipolar Disorder: Exploring Gender‐Related Differences
ABSTRACT Objectives To explore the clinical impact of social determinants of health (SDoH) stress in bipolar disorder (BD) course of illness and to explore potential gender differences in SDoH stress endorsement. Methods 2280 individuals living with BD type I or II (62% women; 67.5% BD‐I) participating in the Mayo Clinic Bipolar Biobank who completed a questionnaire assessing positive and negative‐valent stressors in the 12 months prior to study enrollment were included for this analysis. Six negative stressors were used as proxies of SDoH. Generalized linear models were used to test the association between SDoH stressors and markers of illness severity as well as potential differences by sex by including an interaction term. Results After adjusting for age, sex, and recruitment site, SDoH‐related stressors were significantly associated with a more severe course of illness in both men and women. Except for unemployment rates, women reported more frequently SDoH‐related stress (i.e., lack of family support, financial problems, health coverage and access problems). Conclusions The study found significant gender differences in both the endorsement of specific SDoH stressors and in the prevalence of specific illness severity markers; however, it did not directly test the predictive relationship between gender differences in SDoH and illness severity markers. Future studies aiming to achieve health equity in mental health care should continue assessing social determinants of health stressors, incorporating a gender perspective to better understand their influence on bipolar disorder.
Physician-in-the-Loop Active Learning in Radiology Artificial Intelligence Workflows: Opportunities, Challenges, and Future Directions
Purpose of review Although effective patient safety education is critical to reducing medical errors, little guidance exists on best practices for patient safety curricula. This review explores the current state of patient safety education in anesthesiology and highlights emerging technologies as tools to enhance and personalize education. Recent findings Despite formal mandates from accrediting bodies, patient safety education in anesthesiology lacks standardization in content, delivery, and assessment. Structured clinical training, simulation, and quality improvement projects are common teaching strategies, but novel approaches such as immersive reality (IR), artificial intelligence (AI)-powered agents, gamification, and mobile platforms are gaining traction. AI shows promise in tailoring instruction and identifying high-risk learners, and IR offers tools for both technical and nontechnical skills training. Summary Patient safety education in anesthesiology is evolving with technology. AI and digital tools provide adaptive and interactive learning experiences that may help address current limitations in fixed, generalized curriculum structure and accessibility. However, these innovations require robust validation and thoughtful integration into educational frameworks to realize their full potential.
Real-world outcomes of brexucabtagene autoleucel for relapsed or refractory mantle cell lymphoma: a CIBMTR analysis
Abstract Brexucabtagene autoleucel (brexu-cel) is a chimeric antigen receptor T-cell therapy approved for relapsed/refractory mantle cell lymphoma (R/R MCL). Here, we report real-world effectiveness and safety outcomes of brexu-cel in a prospective study of patients with R/R MCL, including subgroups based on prior treatment with Bruton's tyrosine kinase inhibitor, bendamustine, or autologous hematopoietic cell transplant (auto-HCT) and number of prior therapy lines, using Center for International Blood and Marrow Transplant Research registry data. A total of 476 patients with R/R MCL who received brexu-cel between July 2020 and December 2022 were included in the analysis. With a median follow-up of 13.5 months, the overall response rate was 91% and complete response rate was 82%. One-year overall survival and progression-free survival rates were 76% and 63%, respectively. One-year cumulative incidence of nonrelapse mortality was 8%. Prior auto-HCT was associated with better duration of response within 6 months after infusion (hazard ratio [HR], 0.49; 95% confidence interval [CI], 0.28-0.85) but greater risk of immune effector cell–associated neurotoxicity syndrome (odds ratio [OR], 1.66; 95% CI, 1.06-2.60). Prior bendamustine was associated with increased risk of prolonged thrombocytopenia (OR, 1.90; 95% CI, 1.13-3.21). In patients with 1 to 2 prior therapy lines, relapse or progression was less frequent compared with those with ≥3 prior lines (HR, 0.64; 95% CI, 0.42-1.00). Collectively, our results suggest that real-world outcomes with brexu-cel were consistent with those of the ZUMA-2 trial, regardless of prior therapy type or number of prior therapy lines.
Early Findings from the Multicenter RAPID Consortium on Papillary Craniopharyngiomas
Abstract Craniopharyngiomas are rare parasellar tumors, and papillary craniopharyngiomas (PCPs) represent 8 to 20% of cases. Interim analysis of retrospective data collected from the Registry of Adenomas of the Pituitary and Related Disorders (RAPID). Fourteen U.S.-based academic skull base centers between 2011 and 2023. Patients with PCPs. Demographic, imaging, surgical, and outcome variables. Ninety-nine patients with PCPs were included. The mean age was 51.8 ± 14.7, and 57.6% were male. Most tumors showed mixed cystic/solid components (67.5%), were transinfundibular (50.0%), and were treated with an endoscopic endonasal approach (74.5%), with 51.1% demonstrating gross total resection (GTR). Pituitary stalk was preserved in 51.9%. Permanent arginine vasopressin deficiency was seen in 67.1% and was associated with pituitary stalk sacrifice (p = 0.003). Cerebrospinal fluid leak was the most common nonendocrine postsurgical, 30-day complication (9.1%), reason for return to the operating room (3.1%), and reason for 90-day readmission (8.1%). Most patients (63.9%) received no adjuvant therapy; GTR was associated with decreased radiotherapy use (p = 0.0001). BRAFV600E mutation was detected in 64/69 tumors tested, although only one patient was treated with a BRAF inhibitor. A mean follow-up of 12.3 ± 14.6 months was seen for the group. RAPID consortium enabled the largest real-world clinical information dataset for PCPs. Early findings support that GTR and stalk preservation are important to outcomes. Iterative analysis and discussion of data led to the generation of a framework for future studies to fully leverage the capabilities of multicenter registries.
Neurotoxicants driving glial aging: role of astrocytic aging in non-cell autonomous neurodegeneration
Abstract Astrocytes, the most abundant glial cells in the central nervous system (CNS), play essential roles in maintaining neuronal homeostasis, synaptic regulation, and blood–brain barrier integrity. However, these cells can undergo senescence—a cellular state characterized by irreversible growth arrest and the secretion of proinflammatory factors—in response to aging and pathological stressors, contributing to synaptic dysfunction and neurodegenerative diseases. This review examines the molecular mechanisms driving astrocytic senescence, including oxidative stress, DNA damage, and inflammatory signaling pathways such as NF-κB and the senescence-associated secretory phenotype. A particular focus is placed on the diverse array of known chemical inducers of astrocyte senescence, such as pesticides and heavy metals, which provide critical insights into the processes governing cellular aging in the brain. By analyzing the effects of these inducers, we highlight their implications for neurodegenerative disease progression and brain aging. Understanding astrocytic senescence offers new insights into age-related neuropathology and presents promising avenues for targeted therapies in neurodegenerative disorders induced by environmental toxicants.
