Importance The prevalence of cardiovascular disease differs substantially across neighborhoods. However, few studies have examined the contribution of neighborhood-level structural racism to inequities in cardiovascular health. Objective To investigate the association between neighborhood-level manifestations of structural racism and the prevalence of cardiovascular clinical and behavioral risk factors and cardiovascular diseases. Design, Setting, and Participants This cross-sectional study consisted of 71 915 US census tracts. The Structural Racism Effect Index (SREI) was appended to the 2020 Centers for Disease Control and Prevention’s PLACES dataset. Race and ethnicity were self-reported and obtained from the 2019 American Community Survey 5-year estimates. Data analysis was conducted from June 2024 to October 2024. Exposure The SREI is a composite score of census tract measures within 9 domains affected by structural racism (built environment, criminal justice, education, employment, housing, income and poverty, social cohesion, transportation, and wealth). The SREI scores were categorized into distribution-based quintiles, where higher quintiles represented greater neighborhood structural racism. Main Outcomes and Measures Neighborhood-level prevalence of cardiovascular clinical (high blood pressure, high cholesterol, obesity, and diabetes) and behavioral (current cigarette smoking and no leisure-time physical activity) risk factors and cardiovascular disease (coronary heart disease and stroke). Multilevel-linear mixed models, adjusting for confounders, were used to estimate adjusted prevalence rate ratios (aPRR). Results Among 71 915 census tracts, neighborhoods in the highest quintiles of structural racism were more likely than neighborhoods in the lowest quintile to be in the southern region (quintile 1, 19.9% vs quintile 5, 56.8%). The proportion of the population that was Black was largest in neighborhoods in the highest quintile of structural racism (quintile 1, 2.2% vs quintile 5, 23.0%). After adjustment, compared with the lowest quintile of structural racism, the highest quintile had significantly higher prevalence rates of cardiovascular clinical risk factors, including high blood pressure (aPRR, 1.37; 95% CI, 1.37-1.38), obesity (aPRR, 1.40; 95% CI, 1.39-1.40), and diabetes (aPRR, 1.80; 95% CI, 1.79-1.81). Similarly, for cardiovascular behavioral risk factors, the highest quintile of structural racism had significantly higher prevalence rates of current cigarette smoking (aPRR, 1.84; 95% CI, 1.83-1.85) and no leisure-time physical activity (aPRR, 1.88; 95% CI, 1.87-1.89). Additionally, for cardiovascular diseases, the highest quintile of structural racism had higher prevalence rates of coronary heart disease (aPRR, 1.80; 95% CI, 1.79-1.82) and stroke (aPRR, 1.99; 95% CI, 1.98-2.00). Conclusions and Relevance In this cross-sectional study, structural racism was associated with inequities in neighborhood cardiovascular health, highlighting opportunities for place-based prevention efforts.

PURPOSE Lack of race- and age-diversity in clinical trials adversely affects generalizability of trial results and equity of trial access. Research on barriers to representative accrual has focused on patient-level factors. We aimed to define site-level factors affecting the diversity of accrual to a multicenter clinical trial. METHODS Alliance 191901 (GETSET) is a national randomized controlled trial testing interventions to promote breast cancer endocrine therapy adherence, which oversamples Black women and those under age 50 years at 30% thresholds. A secondary study objective is to examine site-level factors associated with accrual of Black and younger participants. At 50% accrual to the parent study, we performed prespecified analyses of association between site characteristics (region, neighborhood racial composition, Alliance membership type, number of recent accruals to cooperative research group trials) and the proportion of Black patients and younger patients accrued. We also examined trajectories of accrual over time for race- and age-specified subgroups. RESULTS The analysis included 124 sites. Among 590 participants, 9.7% were Black, and 22.4% were age <50 years. Neither site type nor historical accrual volume was associated with Black participant recruitment. Southern sites recruited higher proportions of Black participants (19.0% v 7.3% for West, P < .001). Neighborhood racial composition was positively associated with recruitment of Black participants (16.2% at sites from highest Black composition v 1.4% in lowest, P < .01). Recruitment trajectories of Black participants were slower than target rates, whereas those among non-Black participants were faster. CONCLUSION Neighborhood composition and geographic region were predictors of proportions of Black participants accrued to A191901 sites, but site type and historical accrual volume were not. When trials must limit site selection, identifying sites based on neighborhood composition and geography may be an appropriate tool for increasing trial diversity.

ABSTRACT Newly diagnosed patients with non‐Hodgkin lymphoma (NHL) often have a history of other diseases, and these comorbidities can impact patient treatment and management options, as well as overall survival (OS). We developed the Lymphoma Epidemiology of Outcomes (LEO) comorbidity index (LCI) as a sum of 10 comorbidities adapted from the Self‐Report‐Generated Charlson Comorbidity Index (SRG‐CCI) for use in the LEO cohort, a national prospective study of newly diagnosed NHL. Of the 5502 participants with self‐reported comorbidity data, 3107 (56.4%) were male and the mean age at diagnosis was 60.9 years (range, 18–99 years). The LCI ranged from 0 to 6, with 48.6% having 0, 30.2% having 1, 21.2% having 2 or more comorbidities. With a median follow‐up of 62.4 months among surviving participants, 2099 patients had an event and 1219 died. Continuous LCI similarly predicted both 1‐year mortality (c‐statistic = 0.654) and OS (c‐statistic = 0.655), while it showed a weaker but still statistically significant predictive ability for lymphoma‐specific (c‐statistics = 0.617) and event‐free (c‐statistic = 0.574) survival. Participants with 1 (HR = 1.21, 95% CI 1.05–1.39) and 2+ (HR = 1.80, 95% CI 1.56–2.08) comorbidities had inferior OS compared to those with no comorbidities after adjustment for age and sex (c‐statistic = 0.654), and performance strengthened after adjustment for the International Prognostic Index (c‐statistic = 0.672). LCI predicted OS most strongly in marginal zone (c‐statistics = 0.748) and weakest in T‐cell (c‐statistic = 0.579) lymphoma. The cumulative incidence of death due to lymphoma, lymphoma treatment, and other causes all increased with increasing comorbidities, with the greatest increase observed for death due to other causes. The LCI performs comparable to other published comorbidity indices, supporting its use in the LEO cohort to better model real‐world outcomes and more generally providing an approach to implementing comorbidity indices in cancer survivorship cohorts.

Objective Prior work has identified numerous barriers to standardized outcome measurement in cleft care. The objective of this study was to evaluate a multifaceted implementation strategy to collect standardized outcomes for children with cleft lip and/or palate (CL/P). Design A one-armed, single-site pilot study of a multifaceted implementation strategy. Setting A metropolitan children's hospital. Patients Five-year-old children with CL/P. Interventions A multifaceted implementation strategy for standardized outcome measurement. Main Outcomes Measures The primary outcome measure was penetration of the intervention, defined as the proportion of children for whom the standardized measures of aesthetic, dental, and speech outcomes were collected. Penetration pre-implementation and 12 months post-implementation were compared. The secondary outcome was acceptability of standardized outcome measurement among providers and staff, evaluated with the Acceptability of Intervention Measure. Results The implementation strategy resulted in high penetration of standardized outcome measurement: measurement of aesthetic outcomes increased from 7% to 82% ( p < .0001); measurement of dental outcomes increased from 0% to 56% ( p < .0001); measurement of speech outcomes increased from 29% to 77% ( p = .0001). Acceptability of standardized outcome measurement was high, with 93% of cleft team providers and staff (n = 14/15) reporting that they somewhat or completely agreed that standardized outcome measurement met their approval, was appealing, was welcomed, and was liked. Penetration continued to improve after the implementation period, with high rates of outcome measure collection sustained for four years following implementation. Conclusions Deployment of a multifaceted implementation strategy led to substantial increases in the collection of aesthetic, dental, and speech outcomes among children with CL/P.

Abstract Introduction: Advances in treatment have led to significant increases in survival rates, with over 90% of men diagnosed with prostate cancer (CaP) living at least five years. However, surviving cancer and its treatment often weigh a hefty survivorship burden. Men from the at-risk, vulnerable populations have the greatest burden. This study aims to understand distress among Black CaP survivors (CaPS) who bear the heaviest CaP burden. Method: We conducted key informant interviews with Motivational Interviewing techniques to collect CaPS demographic information, medical history, and multilevel distress evaluation. Descriptive analyses were conducted using SAS. Results: A total of 22 CaPS (aged from 48 to 72) were involved in the study. The majority of CaPS were African American (90.9%) and were diagnosed with stage 2 (31.8%) or stage 3 (36.4%). Over half of them (68.2%) were treated by surgery; most CaPS (90.9%) experienced side effects from prostate cancer treatments. CaPS reported distress in the following domains: Emotional well-being (e.g., Feeling sad, depressed or anxious, mental health) – 40.9%, Death of someone very close to you (e.g., family) – 36.4%, Alcohol use in close family – 36.4%, Experiences of discrimination or racism – 36.4%, Healthcare costs and coverage (e.g., medication, medical services, copay, insurance premium) – 31.8%, Loneliness and isolation – 27.3%, Serious injury/illness in close family (e.g., being a caregiver) – 27.3%, Money and finance – 22.7%, Using telehealth (e.g., using a smartphone or tablet for telephone or over the computer, clinic visit, patient portal, completing online forms, virtual classes) – 22.7%, Marriage, romantic relationships – 22.7%. Discussion: Black CaP survivors (CaPS) who bear the heaviest CaP burden are considered a priority population for research and care. These CaPS identified that their psychological distress was related to both familial and socioeconomic issues. The most endorsed life-stresses included emotional wellbeing, experiences of discrimination/racism, loneliness and isolation, healthcare cost/finance, family health, personal relationship, and telehealth use. The distress data as measured by the life-stress scale are invaluable in better documenting and addressing distress in interventions responsive to specific priority communities. Our novel findings suggest the relevance of grief and loss for these men. 36% reported death of someone close, and 27% indicated distress due to loneliness and isolation. Though the sample size was small, the distress data obtained may inform the science and practice of whole-person survivorship that consider distress emphasizing emotional wellbeing. The study is ongoing, and this abstract presents preliminary results; further muti-variate analyses will be conducted for the conference presentation.

Abstract Background Lung adenocarcinoma in never-smokers is a major public health burden, especially among East Asian women. Polygenic risk scores (PRSs) are promising for risk stratification but are primarily developed in European-ancestry populations. We aimed to develop and validate single- and multi-ancestry PRSs for East Asian never-smokers to improve lung adenocarcinoma risk prediction. Methods PRSs were developed using genome-wide association study summary statistics from East Asian (8002 cases; 20 782 controls) and European (2058 cases; 5575 controls) populations. Single-ancestry models included a PRS with 25 single nucleotide variants (PRS-25), PRS clumping and thresholding (CT), and LDpred2; multi-ancestry models included LDpred2 plus European PRS-128, PRS-CSx, and clumping and thresholding, super learning, empirical Bayes (CT-SLEB). Performance was evaluated in independent East Asian data from the Female Lung Cancer Consortium and externally validated in the Nanjing Lung Cancer Cohort. We assessed predictive accuracy via area under the curve operating procedure (AUC), with 10-year and (ages 30-80 years) absolute risks estimates. Results The best multi-ancestry PRS, using East Asian and European data via CT-SLEB, outperformed the best East Asian-only (LDpred2; AUC = 0.629, 95% confidence interval [CI] = 0.618 to 0.641), achieving an AUC of 0.640 (95% CI = 0.629 to 0.653) and odds ratio of 1.71 (95% CI = 1.61 to 1.82) per standard deviation increase. Nanjing Lung Cancer Cohort validation confirmed robust performance (AUC = 0.649, 95% CI = 0.623 to 0.676). The top 20% PRS group had a 3.92-fold higher lung adenocarcinoma risk than the bottom 20%. Further, the top 5% PRS group reached a 6.69% lifetime absolute risk. Notably, this group reached the average population 10-year lung adenocarcinoma risk at age 50 years (0.42%) by age 41 years, 9 years earlier. Conclusions Multi-ancestry PRS approaches enhance lung adenocarcinoma risk stratification in East Asian never-smokers, with consistent external validation, suggesting future clinical utility.

OBJECTIVE The Centers for Medicare & Medicaid Services (CMS) requires a low C-peptide level for insulin pump coverage unless the individual is β-cell autoantibody positive, which precludes coverage of automated insulin delivery (AID) systems for many people with type 2 diabetes. RESEARCH DESIGN AND METHODS In the Randomized Trial Evaluating the Efficacy and Safety of Control-IQ+ Technology in Adults With Type 2 Diabetes Using Basal-Bolus Insulin Therapy study evaluating the t:slim X2 insulin pump with Control-IQ+ technology, adults with insulin-treated type 2 diabetes were categorized into high C-peptide (n = 195) and low C-peptide (n = 59) groups based on CMS criteria. RESULTS In the AID group, mean HbA1c decreased from baseline by 0.8%, which was significantly greater than in the control group with both high (P &lt; 0.001) and low (P = 0.02) C-peptide levels. Results were similar in participants ≥65 years old. CONCLUSIONS The benefit of AID is present with high and low C-peptide levels. Thus, requiring a low C-peptide level as a prerequisite for AID therapy is not warranted.

Background: There remains significant uncertainty about the fistula rate following palate repair with the Furlow double opposing Z-plasty (Furlow DOZ) technique compared with a straight-line/mucosal incision with intravelar veloplasty (IVVP) technique. Moreover, the relative impact of technique and surgical skill on fistula incidence remains unclear. Methods: A prospective, observational study of cleft palate repair was conducted. Enrollment occurred at 18 U.S.-based cleft centers, including 64 cleft surgeons. The primary outcome was postoperative fistula. Results: Overall, 1219 participants underwent cleft palate repair, 1178 of whom presented for follow-up. Of these, 581 (49.3%) underwent palate repair with the Furlow DOZ technique, 483 (41.0%) with the straight-line/IVVP technique, and 114 (9.7%) with an alternative technique. The overall fistula incidence was 5.3% (62 of 1162 analyzed for fistula occurrence). The fistula incidence was significantly lower in the Furlow DOZ group (2.4% [14 of 564]) than in the straight-line/IVVP group (7.8% [37 of 427]), with a propensity score–weighted risk difference of 5.7% (95% CI, 1.6% to 9.9%; P = 0.007). The fistula incidence varied substantially among surgeons: the top quartile’s fistula rate was 0% (0 fistulas among 417 repairs), whereas the bottom quartile’s fistula rate was 18.9% (31 fistulas among 164 repairs). Conclusions: Fistula incidence following cleft palate repair was significantly lower when using the Furlow DOZ technique, compared with the straight-line/IVVP technique. The effect of surgical technique was smaller, however, than the variation observed between the top and bottom quartiles of surgeons. These findings suggest that changing surgical technique may lead to small changes in fistula incidence, but greater opportunities exist to improve outcomes by improving surgical skill.

Abstract Background & Aims Pregnancy can be a complex and risk-filled event for women with inflammatory bowel disease (IBD). High-quality studies in this population are lacking, with limited data on medications approved to treat IBD during pregnancy. For patients, limited knowledge surrounding pregnancy impacts pregnancy rates, medication adherence, and outcomes. Limited provider knowledge leads to highly varied practices in care affected by local dogma, available resources, individual interpretation of the literature, and fear of harming the fetus. The variations in guidelines by different societies and countries reflect this and lead to confusion for physicians and patients alike. The Global Consensus Consortium is a group of 39 IBD and content experts and 7 patient advocates from 6 continents who convened to review and assess current data and come to an agreement on best practices based on these data. Methods The GRADE (Grading of Recommendations Assessment, Development, and Evaluation) process was used when sufficient published data were available and the RAND (Research and Development) process in those instances where expert opinion was needed to guide consistent practice. Recommendations were informed by the guiding principle that maternal health best supports infant health. Results The topics were divided into ten categories with 34 GRADE recommendations and 35 consensus statements. Conclusions Overall, the goal of the group was to provide data-driven and practical guidance to improve the care of women with IBD around the globe based on the best available research.
