BACKGROUND/UNASSIGNED:Phthalates, widely used as plasticizers, have been associated with adverse pregnancy outcomes, including preterm birth (PTB). This analysis quantifies the global burden of PTB associated with exposure to di (2-ethylhexyl) phthalate (DEHP) and diisononyl phthalate (DINP). METHODS/UNASSIGNED:A disease burden model was constructed using 2018 exposure estimates from available population-level biomonitoring surveys and meta-analyses in regions lacking such surveys. Hazard ratios (HRs) for PTB associated with phthalate exposure were derived from a previous cohort study and applied to regional exposure distributions, and a search from 2016 to 2026 was completed to identify uncertainty intervals for effect estimates. PTB-attributable outcome estimates were obtained from the Institute for Health Metrics and Evaluation's. Phthalate-associated PTB outcomes were calculated using a population attributable fraction approach. FINDINGS/UNASSIGNED:In 2018, 1.97 million DEHP-attributable PTBs (8.74% of global PTBs) were estimated, alongside 74,000 deaths, 6.69 million years of life lost (YLLs) and 1.22 million years of life lived with disability (YLDs). 1.93 million of these incident PTBs, 72,500 deaths, 6.56 million YLLs, and 1.20 million YLDs could be linked to plastics. The highest absolute burden was estimated in the Middle East and South Asia, representing over 54% of estimated attributable PTBs, followed by Africa at 26%. Attributable morbidity and mortality trends differed in accordance with underlying regional patterns of burden. Estimates were similar for DiNP (64,000 deaths, 1.88 million PTB cases, 5.77 YLLs, 1.35 YLDs, and PAF of 8.32%). To account for uncertainties in extrapolating effect estimates from the US, effect estimates from four previous global meta-analyses were also used to calculate uncertainty intervals. Uncertainty intervals revealed as low as 4 times lower estimates for DEHP, and 10 times lower DiNP estimates, highlighting the need for further investigation to refine DiNP associated morbidity and mortality. INTERPRETATION/UNASSIGNED:This model presents the first global estimate of the PTB burden linked to exposure to certain phthalates. Burden was estimated to be disproportionate in South Asia, the Middle East, and Africa. Implementing regulatory measures to limit exposure to phthalates as a class could help reduce the global PTB burden, particularly in and areas with high PTB risk, limited regulations, and growing plastics industries. FUNDING/UNASSIGNED:Funding was provided by Beyond Petrochemicals and National Institutes of Health grant number: P2CES033423.

INTRODUCTION/BACKGROUND:A 2021 federal rule permits opioid treatment programs (OTPs) to provide methadone through mobile medication units (MMUs), creating an opportunity to provide medication for people in residential care facilities. We used simulations to quantify the potential of MMUs to expand methadone access to people residing in residential substance use treatment facilities (RTF), skilled nursing facilities (SNF), and nursing facilities (NF) in New York State under different scenarios. METHODS:For each facility (RTF, SNF, and NF), a need score was created using three items: facility opioid use disorder (OUD) population, driving distance to nearest OTP, and county overdose mortality rate. We then demonstrated potential patient reach following the launch of 50 hypothetical MMUs making one stop per day to the highest need facilities. In refinements, we examined three additional scenarios involving more daily stops and prioritizing rural areas. RESULTS:Our sample included 3214 people with OUD estimated to be housed in 1052 facilities in New York, with the majority in RTFs (51.5%). The demonstrated percentage of OUD population served ranged from 23.5% to 35.8%, and the percentage of facilities served ranged from 23.8% to 37.4%. Each scenario reached a large percentage of rural facilities (73-76%). Prioritizing rural facilities decreased the proportion of OUD population served (10% reduction) but did not substantially increase driving time. Allowing multiple stops increased the proportion of OUD population served (32-36% vs. 24-26%). CONCLUSIONS:Using methods based on location information and spatial relationships, state officials can develop priorities and assess tradeoffs of MMU deployment and distribution strategies.

IntroductionWhile largely preventable, cervical cancer remains a major cause of morbidity and mortality in low- and middle-income countries (LMICs), where gaps in screening uptake persist despite expanding prevention efforts. In many patriarchal settings, men play influential roles in household decision-making and access to healthcare, positioning them as critical but under-engaged stakeholders. There remains limited understanding of how educational strategies to improve health literacy can be designed to effectively engage men in supporting women's screening participation.MethodsWe conducted a qualitative study in northern Ghana to explore men's understanding, priorities, and values related to cervical cancer prevention to inform male-focused educational strategies. Guided by the Consolidated Framework for Implementation Research and the Health Belief Model, 9 in-depth semi-structured interviews were conducted with married adult men recruited from community settings, examining household roles, perceptions of cervical cancer and screening, and preferences for education and engagement approaches. Interviews were conducted in English or Dagbani, audio-recorded, transcribed, and analyzed thematically using a hybrid inductive and deductive approach.ResultsThree cross-cutting themes emerged. Men viewed healthcare professionals as trusted sources of cervical cancer information and described their roles as primary financial decision-makers, with cost and competing household priorities influencing support for screening. Masculine responsibility, particularly related to fertility and family wellbeing, strongly motivated engagement, and messages framed around these themes were more compelling than disease-focused messaging alone. Participants recommended integrating education into routine health services, leveraging healthcare workers, offsetting screening-related costs, and using mass media to initiate awareness and information seeking.ConclusionMen represent pivotal yet underutilized partners in cervical cancer prevention. Educational strategies that align with men's roles, economic realities, and trusted sources of information and address household decision-making barriers may enhance screening uptake while supporting women-centered care. These findings provide implementation-relevant insights to inform male-engaged cervical cancer prevention strategies across diverse LMIC settings.

INTRODUCTION/UNASSIGNED:Poor dental health is linked to poor physical and mental health. This study was aimed to examine the characteristics of U.S. adults that are associated with having seen a dentist in the past year. METHODS/UNASSIGNED:A cross-section of adults aged 18-64 years (N=19,975) from the 2023 National Health Interview Survey was examined. Bivariate analyses examined the associations of sociodemographic and financial variables with recent dental visits in the last 12 months. Multinomial modeling was used to assess these variables to predict 3 outcomes of time since the last dental visit: in the last 12 months; over a year but <10 years; and over 10 years or never, which was the reference category. RESULTS/UNASSIGNED:In young and middle-aged adults, 4.8% of Americans, representing over 9 million people, had either never seen a dentist or not seen a dentist in 10 years or more. The likelihood of a dental visit in the last 12 months increased with education level (no high-school degree versus a graduate or professional degree [AOR=0.21, 95% CI=0.09, 0.50]) and income (income below the federal poverty line versus income in the highest quartile [AOR=0.20, 95% CI=0.11, 0.35]). Having dental coverage in a private plan or Medicaid, compared with having no coverage, predicted having a dental visit within the last 12 months in both multinomial and bivariate analyses. CONCLUSIONS/UNASSIGNED:Access to dental care in young and middle-aged adults is determined by financial ability. Increasing access to dental care could happen once the financial barriers to dental care are reduced, including increasing the age at which a young adult can be covered by a parent's plan and making dental coverage comparable with physical health coverage. Given the current data about the links between dental, mental, and physical health, parity for all care is warranted.

BACKGROUND:Climate anxiety describes emotional responses such as worry or distress related to climate change. While it is common and linked to mental health in the general population, little is known about its relevance for individuals with pre-existing mental disorders. METHODS:A nationwide cross-sectional online survey was conducted in Germany between March and July 2025 among adults with at least one self-reported mental disorder. Participants provided socio-demographic and clinical information and completed four items assessing dimensions of climate-related distress: general concern, perceived impact on mental well-being, perceived effects of climatic events on psychological symptoms, and interference with everyday functioning. Group differences were examined using non-parametric tests, and associations with age were analyzed using Spearman correlations with Bonferroni correction. RESULTS:The sample included 427 participants (mean age 36.5 years; 73% female). Reported climate-related distress levels were relatively low across all dimensions within this sample, with minimal interference with daily functioning. Gender differences were found only for perceived effects of climatic events on psychological symptoms, with women reporting higher impact. Associations with age were weak and not significant after correction. Exploratory analyses indicated some variation across diagnostic groups, but most differences were small and did not remain significant after correction. DISCUSSION/CONCLUSIONS:Climate-related distress among individuals with mental disorders appears present but generally modest and rarely functionally impairing. Weak and inconsistent associations with sociodemographic and diagnostic factors suggest that climate-related distress is not strongly structured by specific diagnoses, supporting its consideration within broader clinical and psychological contexts.

Despite robust evidence that medications for opioid use disorder (MOUD) reduce overdose and mortality, substantial care gaps remain following opioid-related hospital encounters. The opioid use disorder (OUD) Cascade of Care framework conceptualizes progression from identification to treatment initiation and retention, yet limited research has examined how real-world OUD treatment trajectories unfold, particularly across treatment episodes and multiple care settings. This paper describes an NIH-funded study protocol (1R01DA061367-01A1) to conduct a longitudinal observational study using linked administrative data across New York City to characterize OUD treatment trajectories following opioid-related hospital encounters. Using the OUD Cascade of Care framework, we will apply state sequence analysis to identify common patterns of OUD treatment engagement in the year following hospitalization, including transitions between treatment modalities and periods in and out of care. We will examine how care trajectories vary by individual and neighborhood characteristics, and assess associations between trajectories and key outcomes, including rehospitalization, overdose, and mortality. By applying novel data-driven longitudinal methods, this study will advance understanding of the complex, non-linear nature of OUD treatment engagement. Findings will inform health system and policy efforts to identify populations at elevated risk, hospital-based interventions, and opportunities to address gaps in care to reduce overdose-related harms.

BACKGROUND/UNASSIGNED:As life expectancy rises, identifying causes and risk factors for incident acute ischemic stroke (AIS) among the oldest-old (≥80 years) is increasingly important. We examined whether the effect of age at stroke on AIS subtype is mediated by embolic risk factors and whether these factors improve AIS prediction. METHODS/UNASSIGNED:-VASc) and compared preinclusion and postinclusion of embolic risk factors. RESULTS/UNASSIGNED:-VASc: C statistics, 0.63 [95% CI, 0.59-0.67]). CONCLUSIONS/UNASSIGNED:These findings suggest that identification and control of embolic risk factors are critical to reduce stroke risk as people age, and better stroke-specific prediction tools are needed.

OBJECTIVE/UNASSIGNED:We investigated potential racial disparities in the effects of audiometric hearing loss and its treatment on dementia and mortality among 3,602 older adults aged 68-89 years, 22% of whom were self-identified Black race. METHODS/UNASSIGNED:Adjudicated all-cause dementia was determined using neurocognitive test data, proxy reports, and surveillance of hospital records and death certificates. Audiometric hearing loss, defined as the better-ear averaged pure-tone threshold (0.5-4 kHz), was categorized using clinical cutpoints. Multivariable-adjusted Cox proportional hazards models included hearing loss-race interaction terms. RESULTS/UNASSIGNED:-interaction = 0.92]. However, moderate-to-severe hearing loss was associated with a 2.3-fold increase in mortality among Black participants only (95% CI: 1.17, 4.60). CONCLUSIONS/UNASSIGNED:Our findings emphasize the importance of including minoritized populations in hearing treatment research to build an evidence base for policy development and clinical decision-making. Hearing loss affects the health of both Black and White Americans. Racial disparities in hearing healthcare should be addressed to advance health equity for all older adults.
