BACKGROUND/UNASSIGNED:In 2024, the US Environmental Protection Agency tightened the Mercury and Air Toxics Standards (MATS) for emissions of filterable particulate matter (fPM) from coal-fired power plants to 0.010 lb/MMBtu. In April 2025, a presidential proclamation stated that 47 specific power plant companies received a 2-year exemption from the new requirements. The proclamation provided no estimates of the resulting health impacts. METHODS/UNASSIGNED:: 1.095, 95% confidence interval (CI) = 1.064, 1.127; in sensitivity analyses, we employ other CRFs); (4) aggregate results (e.g., by US state). RESULTS/UNASSIGNED:emissions to ~6,900 tons, from ~4,400 tons. We estimate that the additional ~2,500 tons emitted will lead to 32 (95% CI = 22, 43) deaths. The highest mortality is in St. Louis, Missouri, (population: 2.2 million) with an estimated 14 (95% CI = 10,19) deaths. The increased mortality is, for some states (e.g., Missouri, and Pennsylvania), caused by mostly in-state emissions; for other states (e.g., Illinois, Maryland, New Jersey, and Virginia), the cause is out-of-state emissions. DISCUSSION/UNASSIGNED:Results here quantify a portion of the health impacts but leave unquantified nonmortality impacts, impacts from hazardous air pollutant (HAP) exposures, and noninhalation pathways. The reduced computational demands of the air pollution model employed here allows for more timely investigation of government actions than would traditional air dispersion modeling. Sensitivity analyses yielded mortality results that ranged from 47% lower to 169% higher than the core findings. CONCLUSIONS/UNASSIGNED:at the exempted coal-fired power plants will lead to 32 (95% CI = 22, 43) additional deaths.

BACKGROUND:Prior studies have found racial and ethnic disparities in cancer screenings, yet smaller minority ethnic groups are often aggregated. METHODS:Data from the 2021-2022 Community Health Resources and Needs Assessment (Cancer CHRNA) and the 2017-2020 NYC Community Health Survey (CHS) examined the prevalence of breast, cervical, and colorectal cancer screenings among Eastern European, Afro-Caribbean, Latine, Chinese, Korean, South Asian, and Southwest Asian and North African (SWANA) groups in New York City. Multivariable logistic regression models estimated adjusted relative risks of cancer screening outcomes by group. RESULTS:Up-to-date mammogram screening was low (< 70%) among all groups except Afro-Caribbean in the Cancer CHRNA; and among South Asian, Chinese, and Eastern European groups in the CHS. In logistic regression, South Asian and SWANA groups were less likely to have received an up-to-date mammogram compared to the Afro-Caribbean group in the Cancer CHRNA; no group differences were found in the CHS. Up-to-date Pap screening was low (< 70%) among all groups except Latina in the Cancer CHRNA; and among South Asian and Chinese groups in the CHS. In logistic regression, all other groups were less likely to have received an up-to-date Pap test compared to the Latina group in the Cancer CHRNA; and Chinese and South Asian groups were less likely to have received an up-to-date Pap test compared to the Latina group in the CHS. Up-to-date colonoscopy screening was low (< 70%) among all groups in the Cancer CHRNA; and among SWANA, South Asian, Chinese, and Eastern European groups in the CHS. In logistic regression, all groups except Chinese were less likely to have received an up-to-date colonoscopy compared to the Eastern European group in the Cancer CHRNA; and the Chinese and SWANA groups were less likely to have received an up-to-date colonoscopy compared to the Afro-Caribbean group in the CHS. CONCLUSIONS:Disparities in cancer screenings differed by screening type and survey, with larger disparities found among groups in the Cancer CHRNA. System level efforts are needed to monitor cancer screening disparities by disaggregating diverse groups; culturally tailored strategies should be used to raise awareness to increase screening.

INTRODUCTION/UNASSIGNED:The growing availability of AI tools is transforming health and science communication by streamlining content creation and promotion. This study investigates the impact of AI-assisted research summaries on user engagement with the NIH-funded RECOVER program's website and evaluates the efficiency and readability of the content. METHODS/UNASSIGNED:We analyzed Google Analytics 4 data from two distinct periods: one with entirely human-generated content and a second with AI-assisted content. We measured changes in page views, active users, and average engagement time, and assessed the review time and readability of the AI-enhanced summaries. RESULTS/UNASSIGNED:There was no significant change in page views or active users between the two periods. However, average engagement time increased by 4.37 seconds (P = .0461), suggesting AI-assisted content may be more compelling. Human review of AI-drafts averaged 19.88 changes, and readability improved, with the mean Flesch-Kincaid grade level decreasing from 12.28 to 11.56. CONCLUSION/UNASSIGNED:This study demonstrates that AI can be a valuable tool for accelerating the creation of accessible and engaging content. Our findings highlight a crucial balance: while AI can save effort and reduce cost in public engagement efforts, human oversight remains essential to ensure the accuracy, clarity, and accessibility of vital health communications.

This cross-sectional pilot study aimed to examine associations between urinary metabolites of organophosphate (OP) pesticides and semen quality in 42 healthy young men. Participants answered questionnaires, provided semen and urine samples, and had anthropometric measures taken. Urine and seminal plasma were assayed for dialkylphosphate (DAP) metabolites of OP pesticides using high-performance liquid chromatography-electrospray ionization-tandem mass spectrometry. Semen quality parameters were analyzed according to the World Health Organization protocol, and seminal oxidative stress was assayed using MiOXSYS, a galvanic cell-based technology that yields an integrated measure of oxidants and antioxidants. Associations of OP pesticide metabolites with continuous and dichotomous sperm concentration, percent motility, and percent normal morphology, and with seminal oxidative-reduction potential (ORP) were analyzed statistically. OP pesticide exposure was associated with lower overall semen quality. Specifically, ∑DAP metabolites, driven by diethyl metabolites, was inversely associated with percent sperm motility, but this relationship was not mediated by seminal ORP. Seminal ORP was inversely associated with sperm concentration, but OP pesticide exposure was not associated with seminal ORP.

BACKGROUND:Black communities, compared to White communities, are disproportionately targeted with more unhealthy food advertisements on television and social media. Exposure to unhealthy food and beverage marketing is associated with appetitive sensations, purchase intention, and intake behaviors, which may contribute to poor overall diet quality and worsening nutritional disparities in Black communities. Despite the negative effects, food and beverage companies are expanding their reach and harnessing advanced technology to create immersive experiences using virtual reality (VR). Black young adults may be uniquely vulnerable. OBJECTIVE:We aim to explore the effect of a VR-based fast-food marketing experience (compared with a VR-based nonfood control) on purchase intention, arousal, and hunger in a sample of Black and White young adults. METHODS:We will recruit 200 Black and White young adults (aged 18-24 years) from the New York City metropolitan area for a 1-time, 2-hour laboratory-based study. After screening and obtaining informed consent, eligible participants will be randomized to 1 of 2 VR conditions: a VR-based fast-food marketing experience (Wendyverse; experimental) or a VR-based nonfood control (Nikeland). In the Wendyverse, users can order from the restaurant operated by Wendy's, play games, meet others who may be visiting the Wendyverse, and access codes that can be used to obtain free food at physical restaurants. The control condition will be the Nikeland app, where participants can play sports, try on apparel, and engage with celebrity athletes. Study personnel will provide a 5-minute training session to participants before beginning the experiment to ensure that they feel comfortable in the VR environment. Participants will otherwise engage with the VR app independently. The primary outcomes will be fast-food purchase intention, assessed via a self-report questionnaire; arousal, assessed via electrodermal activity or skin conductance; and hunger, assessed via salivary reactivity. We will also conduct secondary analyses to examine interactions by race, ethnicity, and food or nutrition insecurity as a proxy for socioeconomic status. Analyses of covariance and multiple linear regressions will be conducted to examine the effects of VR-based fast-food marketing exposure on the relevant outcomes (compared to the control). RESULTS:This study was funded by the National Institute on Minority Health and Health Disparities in September 2024. Recruitment is expected to begin in September 2025. We expect to complete data collection by October 2026 and begin data cleaning and analysis in November 2026. CONCLUSIONS:On the basis of previous research and data, we anticipate that young adults randomized to view VR-based food and beverage marketing will self-report higher purchase intention and demonstrate stronger arousal and hunger. The data will be used to support future research and improve the understanding of the effects of digital forms of unhealthy food and beverage marketing on young people.

BACKGROUND:Childhood obesity is a global public health issue, which has prompted governments to invest in prevention programmes. We aimed to investigate the effectiveness of parent-focused early childhood obesity prevention interventions globally. METHODS:We did a systematic review and individual participant data meta-analysis. We searched databases and trial registries (MEDLINE, Embase, CENTRAL, CINAHL, PsycInfo, ClinicalTrials.gov, and WHO International Clinical Trials Registry Platform) from inception until Sept 30, 2024, for randomised controlled trials commencing before 12 months of age examining parent-focused behavioural interventions to prevent obesity in children, compared with usual care, no intervention, or attention control. Individual participant data were checked, harmonised, and assessed for integrity and risk of bias. We excluded trials that were quasi-randomised, investigated pregnancy-only interventions, or did not collect any child weight-related outcomes. The primary outcome was BMI Z score at age 24 months (±6 months). We did an intention-to-treat, two-stage, random effects meta-analysis to examine effects overall and for prespecified subgroups. We assessed certainty of evidence using Grading of Recommendations Assessment, Development, and Evaluation. This study is registered with PROSPERO, CRD42020177408. FINDINGS/RESULTS:=0·01; n=6505; 2623 missing). Findings were robust to prespecified sensitivity analyses (eg, different analysis methods and missing data), and we found no evidence of differential intervention effects for prespecified subgroups including priority populations and trial-level factors. INTERPRETATION/CONCLUSIONS:These findings indicate that examined parent-focused behavioural interventions are insufficient to prevent obesity at age 24 months (±6 months). This evidence highlights a need to re-think childhood obesity prevention approaches. FUNDING/BACKGROUND:Australian National Health and Medical Research Council.

BACKGROUND:Few studies have comprehensively examined health outcomes among older caregivers. We aimed to describe older caregivers and characterize risks for mortality and hospitalization compared to non-caregivers. METHODS:Caregiving status and characteristics were determined for Atherosclerosis Risk in Communities (ARIC) Study participants via a one-time telephone assessment in 2015. All-cause mortality was identified from active surveillance, state records, and linkage to the National Death Index through December 31, 2021. Hospitalizations were identified from active cohort surveillance. Cox proportional hazard models assessed risks of mortality and hospitalization. RESULTS:Among 5,239 ARIC participants [mean age: 75.4 (SD 5.1) years; female: 60.0%; Black: 18.9%], 427 (8.2%) reported caregiving. Caregivers were generally female and younger as compared to non-caregivers. Most caregivers provided care for their spouse (55.0%) and 28.3% reported spending >40 hours/week on caregiving activities. Caregivers had modestly better cognitive scores but were similar to non-caregivers in the number of comorbidities and self-rated health. During a mean 5.4 (SD 1.3) years of follow-up, caregivers had a lower risk of mortality than non-caregivers (18.7% vs. 23.8%), although not statistically significant in fully adjusted time-to-event models (hazard ratio [HR]=0.84; 95%CI:0.67-1.06). Caregivers and non-caregivers had similar risk of hospitalization (63.5% vs. 64.9%; HR = 1.00; 95%CI:0.89-1.14). CONCLUSIONS:Older caregivers provide substantial care while facing their own health challenges. Despite similar baseline comorbidity burdens as non-caregivers, caregivers had a lower risk of all-cause mortality over the 6 years of follow-up. Future studies should examine the potential protective factors of caregiving in older age to inform caregiver support initiatives for older adults providing care.

Maternal mental health during the perinatal period has been linked to the development of infant emotion regulation capacity, largely through its impact on caregiver-infant interactions during the first year of life. The majority of studies have focused on the effects of maternal depression, even though maternal anxiety is more prevalent and its effects on infant outcomes are less well understood. The current study aims to 1) explore differences in infant affect and regulatory behaviors across two commonly implemented infant stress-induction paradigms and 2) evaluate the differential effects of depression and anxiety on infant regulatory behaviors. Six-month-old infants and their mothers (N = 126) completed two tasks remotely in the home: the Arm Restraint task and the Still-Face Paradigm. Maternal depression and anxiety symptoms were measured using the Edinburgh Postnatal Depression Scale (EPDS) subscales. Within-person results indicated no significant associations among infant regulatory behaviors nor infant reactivity across the two paradigms. Additionally, no significant associations were found between maternal mental health and infant regulatory behaviors during the Still-Face Paradigm. However, higher EPDS composite scores were associated with fewer infant avoidance behaviors during the Arm Restraint task, and this result was driven by items on the anxiety subscale. These findings suggest that infant regulatory behaviors may differ depending on task used and may also be influenced by subclinical levels of maternal anxiety, but not maternal depression.
