Increased Axillary Nodal Metastasis in Patients with Breast Cancer and Limited English Proficiency
Amburn, Thomas; Louie, Daniel; Schwartz, Shira; McFarlane, Anita; Ravenell, Joseph; Joseph, Kathie-Ann
BACKGROUND:Patients with breast cancer and limited English proficiency (LEP) experience barriers to care that may result in greater disease burden. We aim to evaluate breast cancer presentation and pathologic characteristics of patients with LEP compared with patients with English proficiency (EP). PATIENTS AND METHODS/METHODS:We performed an institutional review board (IRB)-approved, retrospective review of prospectively collected patient-reported data among a multilingual population evaluated within a New York City safety-net health system between 2018 and 2025. Comparative analysis and logistic regression were used. RESULTS:) compared with EP (31.2% versus 18.5%; p = 0.012) and was significantly associated with completion axillary lymph node dissection compared with EP (12.8% versus 3.6%; p = 0.0041). Patients with LEP had significantly longer time-to-therapy intervals from biopsy to first therapy compared with EP (52 versus 49 days; p = 0.041). On multivariate analysis, both LEP and delays to first therapy were significantly associated with axillary nodal metastasis. CONCLUSIONS:Patients with breast cancer and LEP were significantly more likely to have axillary nodal metastasis compared with patients with EP. Increased axillary nodal metastasis in this population may, in part, be due to lack of screening and delays to breast cancer treatment.

Early-life residential mobility as a social determinant of mood disorder risk: A nationwide longitudinal cohort study in South Korea
Hong, Jongsoo; Lee, Myeonggyun; Sung, Ho Kyung; Kim, Sujin; Kim, Byoungjun; Park, JungHo
BACKGROUND/UNASSIGNED:Residential mobility during childhood has been widely discussed as a potential source of psychosocial disruption, yet population-level longitudinal evidence remains limited outside Western contexts. This study examined whether early-life residential mobility is associated with the subsequent risk of mood disorders in South Korea. METHODS/UNASSIGNED:We conducted a nationwide retrospective cohort study using the Korean National Health Insurance Service database (N = 6,668,197). Residential mobility was assessed over a six-year period spanning late childhood and early adolescence (ages 10 to 15). Incident clinical diagnoses of mood disorders (ICD-10: F31 to F39) were ascertained between ages 16 and 25. Multivariable Cox proportional hazards models were used to estimate hazard ratios and 95% confidence intervals, adjusting for key available covariates, including sex and household income. RESULTS/UNASSIGNED:A greater frequency of residential relocation was significantly associated with a higher risk of mood disorders. Relative to non-movers, the adjusted hazard ratios were 1.12 (95% CI: 1.12-1.13) for 1-move, 1.27 (95% CI: 1.25-1.28) for 2-move, and 1.41 (95% CI: 1.38-1.44) for 3+ moves. Associations were stronger among lower-income groups, and similar graded patterns were observed across diagnostic subtypes. Sensitivity analyses excluding early diagnoses yielded comparable results. Early-life residential mobility was associated with an elevated and progressively increasing risk of mood disorders in South Korea. CONCLUSIONS/UNASSIGNED:These findings underscore the importance of residential stability during sensitive developmental periods and suggest that residential mobility may represent a potentially modifiable social and environmental risk factor for later mental health. Future research incorporating intergenerational data may help clarify underlying mechanisms.

Factors associated with viral suppression and antiretroviral therapy adherence among adolescents and young adults living with HIV in the African Cohort Study
Brault, Marie A; Ahonkhai, Aima A; Frndak, Seth; Colt, Susannah; Crowell, Trevor A; Parikh, Ajay; Duff, Emma R; Sing'oei, Valentine; Owuoth, John; Maswai, Jonah; Parker, Zahra; Bahemana, Emmanuel; Kibuuka, Hannah; Vermund, Sten H; Shah, Neha; Ake, Julie A; ,
INTRODUCTION/BACKGROUND:Adolescents and young adults living with HIV (AYLHIV) experience poor outcomes across the care continuum, and most reside in sub-Saharan Africa. The African Cohort Study (AFRICOS) provides an opportunity to examine HIV outcomes in this population across Kenya, Nigeria, Tanzania, and Uganda. METHODS:We conducted a cross-sectional analysis of AYLHIV aged 15-29 years, enrolled in AFRICOS 2013-2023, and on antiretroviral therapy (ART) ≥ six months. Primary outcomes were HIV viremia and 30-day ART non-adherence. Factors included HIV acquisition route, ART duration, ART class, and site. We used multivariate robust Poisson regression to estimate relative risks (RRs) and 95% confidence intervals (CIs). Site directors were surveyed to assess youth-friendly services. RESULTS:Among 656 participants, the median age was 20.0 years (IQR 17.5-23.3); 41.6% were male, 61.6% had perinatally-acquired HIV, and median duration since HIV diagnosis was nine years. At enrollment, 83.8% had viral suppression (<200 copies/mL) and 80.2% were ART adherent. ART regimen and clinic site were associated with viral suppression: youth on integrase vs. protease inhibitor-based regimens (adjusted relative risk (aRR) 0.38, CI 0.23-0.63, p<0.001), and in Uganda (aRR 0.42, CI 0.20-0.90, p=0.026) or Kisumu, Kenya (aRR 0.40, CI 0.22-0.76, p=0.005) had lower likelihood of non-suppression. Compared to Nigeria, participants from other sites were less likely to report non-adherence (unadjusted RR 0.31-0.44). Youth-friendly service provision varied. CONCLUSIONS:Viral suppression and ART adherence were high among AYLHIV in AFRICOS. Clinic site and ART regimen were associated with outcomes, highlighting the importance of health system factors.

The trans care paradox: Mental health disparities among transgender and nonbinary patients in a trans-protective environment
Breslow, Aaron S; Babbs, Gray; Cavic, Elizabeth; Thomas, Iby; Progovac, Ana M; Restar, Arjee; Sims, Ginette M; Zelaya, David G; Hanna, David B; Datta, Debjyoti; Reopell, Renée; Golub, Sarit; Alpert, Jonathan; Cook, Benjamin Lê; Garrett-Walker, J
This study examines mental health disparities among transgender, nonbinary, and gender-expansive (hereinafter "trans") patients within a large urban health care system in the Bronx, New York-a relatively trans-protective legislative environment-amid escalating federal anti-trans legislation. Using electronic health record data (2015-2023) from a large safety-net health care system, we conducted a retrospective cohort study comparing mental health outcomes and services among trans (n = 2,898) and cisgender (n = 29,818) adult patients. We applied the Institute of Medicine rank-and-replace method to isolate disparities attributable to systemic inequities independent of clinical need. Despite greater engagement, trans patients faced disproportionately poor outcomes. Trans patients had more than twice the prevalence of mental health concerns compared with cisgender patients (all ps < .001), including higher rates of mood disorders (10.9% vs. 2.6%) and anxiety disorders (9.7% vs. 3.1%). Trans patients had higher predicted means of primary care utilization (40.92% vs. 38.45%, disparity: 2.48 percentage points, p < .001), minimally recommended mental health treatment (21.18% vs. 19.44%, disparity: 1.74 percentage points, p < .001), suicide-related visits (2.3% vs. 1.2%, disparity: 1.1 percentage points, p < .001), emergency department mental health visits (8.6% vs. 6.4%, disparity: 2.2 percentage points, p < .001), and inpatient mental health stays (0.13 vs. 0.09 stays per year, p < .001). Intersectional analyses revealed compounded disparities for Black and Hispanic patients. These findings highlight a persistent "care paradox," wherein greater health care utilization fails to mitigate adverse outcomes. Results underscore the need for integrated, trans-affirming interventions at the health care system level, broader structural reforms, and community-driven efforts to bolster trans mental health.

Bansah, Eyram Cyril; Hu, Xiao; Ballew, Shoshana H; Grams, Morgan E; Nambi, Vijay; Selvin, Elizabeth; Coresh, Josef; Boerwinkle, Eric; Yu, Bing; Matsushita, Kunihiro
BACKGROUND/UNASSIGNED:Lower extremity peripheral artery disease (PAD) is a major contributor to cardiovascular morbidity and mortality; however, the metabolic pathways underlying disease development and progression are poorly understood. METHODS/UNASSIGNED:We conducted a prospective cohort study of 3759 participants from the ARIC study (Atherosclerosis Risk in Communities; mean age, 53.5 years; 60% women; 62% Black participants) with untargeted metabolomic profiling at baseline (1987-1989). Incident PAD (458 cases) and its severe form with rest pain or tissue loss, critical limb ischemia (CLI; 135 cases), were identified through hospitalization codes over a median follow-up of 27 years. We used Cox regression with adjustment for traditional risk factors and accounted for multiple testing using a false discovery rate correction at a threshold of 0.05. Risk prediction improvement was evaluated using Harrell C statistics and the net reclassification improvement. RESULTS/UNASSIGNED:Thirteen metabolites were significantly associated with incident PAD and primarily reflected dysregulated glycemic control, impaired redox balance, and altered lipid remodeling (eg, higher levels of mannose and lower levels of 1,5-anhydroglucitol, gamma-glutamyl dipeptides, and lysophospholipids). For CLI, 18 metabolites were identified, 11 of which were unique to CLI and reflected intensified oxidative and bioenergetic stress (eg, homocitrulline, arabonate, and 1-linoleoylglycerol). Metabolites significantly improved risk prediction for PAD beyond traditional risk factors (∆C statistic, 0.017 [95% CI, 0.008-0.025] from a base C statistic of 0.770; net reclassification improvement, 0.053 [95% CI, 0.018-0.083]) and particularly CLI (∆C statistic, 0.041 [95% CI, 0.018-0.064] from a base C statistic of 0.823; net reclassification improvement, 0.176 [95% CI, 0.085-0.268]). CONCLUSIONS/UNASSIGNED:Distinct metabolomic profiles were associated with incident PAD and CLI years before clinical onset, highlighting dysregulated glycemic control, impaired redox balance, and altered lipid remodeling as key underlying pathways. These findings suggest that circulating metabolites may serve as early indicators of metabolic health relevant to PAD risk identification and progression to advanced disease.

Predictive Utility of Coronary Artery Calcium Score Added to the PREVENT Atherosclerotic Cardiovascular Disease Equations
Huang, Xiaoning; Petito, Lucia C; Allen, Norrina B; Blankstein, Ron; Blumenthal, Roger S; Coresh, Josef; Greenland, Philip; Ho, Jennifer E; Khera, Amit; Lloyd-Jones, Donald M; Rangaswami, Janani; Stein, James H; Ndumele, Chiadi E; Khan, Sadiya S; Shah, Nilay S
IMPORTANCE/UNASSIGNED:The 2026 American College of Cardiology/American Heart Association/Multisociety Dyslipidemia Guideline newly recommends selective use of coronary artery calcium (CAC) scoring based on a 10-year risk of 3% to less than 10% estimated with the Predicting Risk of Cardiovascular Disease EVENTS (PREVENT) atherosclerotic cardiovascular disease (ASCVD) equations. However, the utility of CAC scoring alongside the PREVENT equations for ASCVD risk estimation is not known. OBJECTIVE/UNASSIGNED:To determine the change in predictive utility when adding CAC scores to the PREVENT-ASCVD equations. DESIGN, SETTING, AND PARTICIPANTS/UNASSIGNED:Longitudinal observational cohort study conducted at 6 sites in the United States and enrolling adult participants aged 45 to 79 years without ASCVD at baseline in the Multi-Ethnic Study of Atherosclerosis. EXPOSURES/UNASSIGNED:Ten-year ASCVD risk with the PREVENT-ASCVD equations before and after adding CAC scores. MAIN OUTCOMES/UNASSIGNED:Performance metrics for estimation of risk of fatal and nonfatal ASCVD, assessed using the Harrell C statistic, calibration, and net reclassification improvement (NRI) for newly defined ASCVD risk categories: low (<3%); borderline (3% to <5%); intermediate (5% to <10%); and high (≥10%). RESULTS/UNASSIGNED:A total of 6098 participants were included. At baseline, participant mean age was 61.4 (SD, 9.6) years, 52% were female, mean estimated 10-year ASCVD risk was 6.4% (SD, 4.8%) with the PREVENT-ASCVD base equations, and 49% had a CAC score greater than 0. During 10 years of follow-up, 366 (6%) experienced an ASCVD event. The Harrell C statistic for the PREVENT-ASCVD base equations was 0.73 (95% CI, 0.70-0.75). After adding CAC to the PREVENT-ASCVD base equations, the change in Harrell C statistic was 0.02 (95% CI, 0.01-0.03), and the categorical NRI was 0.095 (95% CI, 0.053-0.137). The calibration slope for the PREVENT-ASCVD base equations was 1.09 (95% CI, 0.93-1.25), and for the PREVENT-ASCVD base plus CAC equations was 0.92 (95% CI, 0.81-1.03). Among those at borderline risk, incident ASCVD occurred in 1.9% of those with CAC score of 0, 3.9% with CAC greater than 0 and less than 100, 7.4% with CAC 100 or greater and less than 300, and 14.3% with CAC 300 or greater. CONCLUSIONS AND RELEVANCE/UNASSIGNED:Among US adults aged 45 to 79 years, addition of CAC score to the PREVENT-ASCVD equations across all risk groups overall only modestly improved and, in some groups, did not change model discrimination and reclassification. Reclassification results support selective use of CAC in those with borderline to intermediate risk estimated by the PREVENT-ASCVD equations.

Prompting generative artificial intelligence to create plain language patient education materials
Frey, Sean M; Milne Wenderlich, Andrea; Craig, Crystal; Yin, H Shonna; Montes, Guillermo
OBJECTIVES/OBJECTIVE:Generative artificial intelligence (AI) holds promise for creating patient education materials (PEM). However, AI-produced content is often difficult to read. Prompts for AI to write at a lower reading level either fail to meet recommended targets (≤6th grade) or demonstrate inconsistent results. We aimed to determine whether a new AI prompt for plain language would create PEMs that are easier to read, understand, and act upon. METHODS:We analyzed PEMs from two websites (HealthyChildren.org, UpToDate) and two generative AI programs (ChatGPT, Gemini). For each AI program, we used a basic prompt and an advanced prompt to generate separate documents. From these sources, we collected six sets of PEMs about five acute pediatric conditions, evaluated them using a panel of readability indices, and used ANOVA to compare average readability scores between sources. Two pediatricians assessed understandability and actionability using the Patient Education Materials Assessment Tool (PEMAT). We calculated mean PEMAT scores, with values > 70% considered understandable/actionable. RESULTS:ChatGPT (advanced prompt) created PEM with the lowest mean grade reading level (5.8; SD 0.84) and highest PEMAT scores (91% understandable, 84% actionable). Documents from generative AI using the advanced prompt and UpToDate had mean readability scores ≤ 6th grade, with significantly better readability than AI-generated documents using the basic prompt or HealthyChildren.org. All sources except HealthyChildren.org had mean understandability > 70%; AIs using the advanced prompt and UpToDate exceeded the actionability threshold. CONCLUSIONS:A plain-language prompt for generative AI created PEMs that were readable, understandable, and actionable, with comparable results across two AI programs. PRACTICE IMPLICATIONS/CONCLUSIONS:Healthcare providers can use this new plain-language prompt for generative AI programs to quickly create free, patient-friendly PEM about acute healthcare topics. As these AI programs were not trained to provide medical guidance, medical professionals should continue to review PEM prior to sharing with patients.

BACKGROUND AND OBJECTIVES/OBJECTIVE:Patients with epilepsy (PWE), especially temporal lobe epilepsy (TLE), experience impaired memory for personally experienced events. However, current assessments of episodic memory are limited in their ecological validity with a potential to miss detection of subtle cognitive decline. We conducted an exploratory study to determine whether a naturalistic film-viewing task with open-ended spoken recall could detect memory differences between TLE patients and healthy controls (HCs). METHODS:TLE patients (ages 18-60, fluent in English, not legally blind) were recruited from a Level 4 Epilepsy Center (2018-2024). TLE diagnosis was based on seizure semiology, MRI Brain, and EEG. TLE patients scored 22/30 on the Montreal Cognitive Assessment (MOCA); HCs scored 26/30. Subjects watched 6 short films and then freely recalled film details. Spoken responses were recorded, transcribed, segmented, and scored for film- and event-level recall. Recall order was assessed using the Damerau-Levenshtein distance. Semantic and causal centrality were quantified using sentence embeddings and rater-identified causal links, respectively. Beta regression with cluster-robust standard errors assessed group and centrality effects on recall probability. Beta regression evaluated the influence of age, MOCA, and testing platform on sequence recall error. RESULTS:We recruited 51 subjects (27 TLEs; 24 HCs, 70.1% F, mean 29.9 ±8.3 years). TLE patients and HCs showed similar recall of films (HC 89% ±11% vs TLE 88% ±18%, p = 0.54), coarse-grained events (HC 50% ±16% vs TLE 44% ±18%, p = 0.19) and fine-grained events (HC 25%±10% vs. TLE 22%±12%, p=0.17). Both groups recalled high causal centrality events better. However, TLE patients showed significantly greater fine-grained event sequence deviations at recall than HCs (HC 15% ±13% vs TLE 23% ±18%, p = 0.02, Hedges' g = 0.85, Cliff's δ = 0.51), with RTLE demonstrating more sequence deviations than HCs (15%±13 vs. 29%±21% p = 0.021) Age, education, MOCA, and performance on standard verbal and visual memory tasks were unrelated to film, event, and sequence recall performance. DISCUSSION/CONCLUSIONS:We demonstrate that a short film task with spontaneous spoken recall can identify group level differences in episodic memory. TLE patients demonstrate impaired sequence memory despite intact film- and event-level recall compared to healthy controls. Sequence memory may represent a subtle manifestation of memory impairment that is not detected by standard cognitive testing.

OBJECTIVE:To evaluate whether there is an association between a maternal classification of Long COVID and adverse pregnancy outcomes. METHODS:RECOVER (Researching COVID to Enhance Recovery)-Adult is a multicenter prospective longitudinal cohort study of adults with and without prior severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection enrolled from October 2021 to January 2024. This analysis included participants with a SARS-CoV-2 infection and at least one symptom survey for classification of Long COVID status recorded before or during pregnancy. Participants were classified as either likely having Long COVID (LCRI [Long COVID Research Index] score of 11 or higher) or as having Long COVID-indeterminate (LCRI score 0-10), with comparisons made between groups. The primary outcome was preterm birth before 37 weeks of gestation. Secondary outcomes included hypertensive disorders of pregnancy, cesarean delivery, neonatal intensive care admission, and small-for-gestational-age birth weight (below the 10th percentile). Propensity score methods with full matching were used to balance differences in baseline characteristics in estimating an average treatment effect, with a sensitivity analysis estimating the average treatment effect among the treated. RESULTS:Among 603 participants, 118 (19.6%) were classified as likely having Long COVID before or during pregnancy. Participants classified as likely having Long COVID were more likely to have specific adverse social determinants of health (difficulty covering expenses and paying bills, food insecurity, missed care because of cost, medical discrimination) and had higher prepregnancy body mass index (BMI) than those who were classified as having Long COVID-indeterminate. In the primary average treatment effect analysis, there was no association between likely Long COVID and preterm delivery (adjusted outcome rate 8.1% exposed vs 9.6% unexposed, absolute risk reduction [ARR] 0.82, 95% CI, 0.36-1.90) or secondary outcomes. In average treatment effect among the treated sensitivity analyses, likely Long COVID was similarly not associated with preterm delivery (ARR 1.11, 95% CI, 0.60-2.06) but was associated with an increased risk of hypertensive disorders of pregnancy (adjusted outcome rate 39.0% exposed vs 25.9% unexposed, ARR 1.51, 95% CI, 1.12-2.03) but not with other secondary outcomes. CONCLUSION/CONCLUSIONS:A classification of likely Long COVID was not significantly associated with preterm birth or several other adverse pregnancy outcomes. However, the association with hypertensive disorders of pregnancy in the average treatment effect among the treated analysis highlights the need for further research.

Prenatal Organophosphate Exposure and Autism-Related Traits in Children
Cavalier, Haleigh M; Volk, Heather E; Kivumbi, Apollo; Liu, Mengling; Lyall, Kristen; Afanasyeva, Yelena; Chen, Yu; Wang, Yuyan; Kannan, Kurunthachalam; Li, Zhongmin; Sherris, Allison R; Croen, Lisa A; Schmidt, Rebecca J; Bennett, Deborah H; Ames, Jennifer L; Breton, Carrie V; Bakian, Amanda V; Bastain, Theresa M; Alkhouri, Nicole B; Eick, Stephanie M; Goodrich, Jaclyn M; Schantz, Susan L; O'Connor, Thomas G; Karagas, Margaret R; Herbstman, Julie B; Trasande, Leonardo; Ghassabian, Akhgar; ,
IMPORTANCE/UNASSIGNED:Organophosphate pesticides (OPs) are established neurotoxicants; prenatal OP exposure is widespread in the US population, primarily through diet. Evidence linking prenatal OP exposure to autism spectrum disorder (ASD) and autism-related traits remains inconsistent. OBJECTIVE/UNASSIGNED:To examine the association between prenatal OP exposure and autism-related traits in childhood and to assess potential differences in the association by child sex and maternal diet. DESIGN, SETTING, AND PARTICIPANTS/UNASSIGNED:This pooled prospective cohort study used harmonized data from mother-child pairs from 20 study sites in the Environmental influences on Child Health Outcomes (ECHO) cohort. Participants were recruited from January 1997 through December 2019, and autism-related outcomes were assessed in children ages 2 to 19 years. Data analysis was performed from April 2024 and November 2025. EXPOSURE/UNASSIGNED:Prenatal OP exposure using urinary concentrations of 3,5,6-trichloro-2-pyridinol (TCPy) and the sum of 6 dialkyl phosphate (ΣDAP) metabolites. MAIN OUTCOMES AND MEASURES/UNASSIGNED:Parents reported autism-related traits in children using the Social Responsiveness Scale (SRS). Multivariable linear, quantile, and logistic regression models were used to estimate associations between biomarkers and SRS T scores overall and by child sex, adjusting for maternal sociodemographic and behavioral factors. We further adjusted for dietary factors in additional models and tested effect modification by maternal diet quality in exploratory analyses. RESULTS/UNASSIGNED:Among 3339 mother-child pairs examined, mean (SD) maternal age was 31 (6) years, 1665 children (49.9%) were female, and the SRS was administered at a mean (SD) age of 6.4 (3.87) years. Crude or minimally adjusted models suggested inverse associations between prenatal TCPy or ΣDAP levels and SRS scores, but these associations attenuated and lost statistical significance after full adjustment (β per doubling of TCPy concentration [ng/mL] = -0.13; 95% CI, -0.57 to 0.31; β per doubling of ΣDAP [nmol/L] = -0.42; 95% CI, -1.03 to 0.19). Results were consistent across sex-stratified models, secondary analyses using quantile and logistic regressions, various sensitivity analyses, and after adjustments for dietary confounders. There was no evidence of effect modification by diet quality. CONCLUSIONS AND RELEVANCE/UNASSIGNED:In this large, prospective cohort study among the ECHO cohort, prenatal OP exposure was not associated with autism-related traits in childhood. Given the known adverse impacts of pesticides in other contexts, further research should consider interactions with other factors, genetic susceptibility, higher exposures, or combined chemical mixtures.
