However, whether exposure to PFAS is associated with liver cancer risk remains unclear.METHODSWe conducted a matched nested case-control study among 12 prospective cohort studies located in the United States. Pre-diagnostic PFAS, namely perfluorooctanesulfonate (PFOS), perfluorooctanoate (PFOA), and perfluorohexanesulfonate (PFHxS), were measured from blood samples among 853 individuals who developed liver cancer and 853 matched control participants.

It has been suggested that population-weighted spatial averages would perform better in remote regions with large temperature and population variability. This would be particularly true in regions other than North America and Europe where outcome data is often only available on a crude spatial scale, but no studies have examined this in such regions, where temperatures can be particularly hot.OBJECTIVEUsing the Middle East as a climate hotspot, our objective was to illustrate the utility of population weighting temperature exposures in understudied regions with large health data aggregation areas.METHODSWe used a daily 1km × 1km temperature dataset for 152 administrative regions in 12 Middle Eastern countries. From 2003 to 2020, for each administrative region, we computed daily minimum and maximum population-weighted and unweighted spatial average temperatures. To illustrate, we examined temperature-mortality associations in two countries: Kuwait and Jordan. We used distributed lag non-linear models to estimate the daily timeseries temperature-mortality associations in using three temperature exposure measurement approaches: station temperatures, unweighted spatial averages, and population-weighted temperatures. For each scenario, we fitted country-specific optimized parameters and compared them using three metrics: 1) exposure-response relationships, 2) minimum mortality temperatures and 3) attributable mortality estimates.RESULTSThe study region had geographically sporadic yet densely populated areas within each country. In both Kuwait and Jordan, population-weighted and unweighted spatial average temperatures resulted in fairly similar exposure-response curves, whereas both were notably different from station temperatures. Minimum mortality temperatures were 30.2, 28.6, and 28.3°C in Kuwait for station, unweighted spatial average, and population-weighted temperatures, respectively. In Jordan, the corresponding temperatures were 20.6, 20.9, and 20°C. Heat attributable mortality calculated using population-weighted temperatures increased by 15% compared to the traditionally used station temperatures in Kuwait and Jordan, respectively, and -0.4% and 5% compared to unweighted spatial average temperatures.DISCUSSIONSpatial averaging, whether weighted or unweighted, is a valuable tool for estimating heat-attributable mortality. This is especially true in regions like the Middle East, where granular temperature data are often unavailable and health studies are urgently needed. Population-weighted temperatures may better capture localized exposures in areas with significant population clustering, though their exact added effect on top of unweighted spatial averages remains a tentative conclusion.. https://doi.org/10.1289/EHP16010.","PeriodicalId":11862,"journal":{"name":"Environmental Health Perspectives","volume":"88 1","pages":""},"PeriodicalIF":10.4,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144114291","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, this association is often highly confounded by factors such as diet and poverty. The gut virome may influence respiratory health independent of the gut microbiome. We recently demonstrated in a randomized waitlist-controlled trial (ClinicalTrials.gov NCT03351504) that a clean lighting intervention reduced personal exposure to air pollution among adult women in rural Uganda.OBJECTIVESTo determine the effect of a solar lighting intervention on changes to the gut microbiome and virome and secondarily to determine association between these changes on lung health.METHODSBetween 2018 and 2019, we collected stool samples and assessed respiratory symptoms and spirometry from 80 adult women living in rural Uganda at baseline, 12 and 18 months post-randomization. The intervention group received a solar lighting system after randomization, while the waitlist-controlled group received one at 12 months. Deep metagenomics sequencing of stool was performed and profiled for non-viral and viral taxonomic composition. The primary analysis focused on pre- vs. post-intervention changes due power considerations, adjusting for potential confounding by age, diet, antibiotic use, and season. A sensitivity analysis was conducted using intention-to-treat principles. When comparing pre- vs. post-intervention periods, we used sparse partial least squares models to identify non-viral and viral signatures of reduced air pollution exposure. Mixed effects models were used to evaluate changes in health outcomes as well as associations between microbial signatures of reduced air pollution exposure and health.RESULTSThe average age was 39.2 years. The solar lighting intervention led to larger changes in viral compared to non-viral microbial community structure and differential abundance of bacteria, eukaryotes, and viruses. Provision of solar lighting systems was associated with a reduction in the presence of respiratory symptoms from 57.1% to 36.1% (p = 0.002) while there was no impact on lung function. Microbiome and virome signatures had AUCs of 0.74 and 0.76 respectively, in predicting pre- vs. post-intervention stool samples. Microbiome signatures were associated with a lower risk of respiratory symptoms (OR 0.68 (0.49-0.94), p = 0.020).CONCLUSIONAmong adult women living in rural Uganda, both non-viral and viral components of the gut microbial community changed after a clean lighting intervention. Microbiome signatures reflective of lower air pollution exposures were associated with improved respiratory symptoms. These observations suggest that air pollution may influence lung health through the gut-lung axis, warranting further exploration in future intervention studies. https://doi.org/10.1289/EHP16002.","PeriodicalId":11862,"journal":{"name":"Environmental Health Perspectives","volume":"4 1","pages":""},"PeriodicalIF":10.4,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144114290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the extent of this impact remains unclear and could be better understood through the collaborative use of advanced predictive and explanatory analytical tools, alongside, an up-to-date dataset on zoonotic spillover events.OBJECTIVEThe main objective is to develop and evaluate an integrated modeling framework to predict and explain spatial patterns and nonlinear relationships of zoonotic spillover events, using updated datasets and the human modification index to differentiate anthropogenic pressures.METHODSOur study expanded the historical datasets to include recent spillover events and a comprehensive set of predictors. By combining robustness of finely-tuned stacking algorithms with structural equation modeling, we considered global heterogeneity in relative reporting adequacy and mapped spillover patterns at different scales. Using the human modification index, we disentangled anthropogenic processes modifying natural ecosystem across land modification gradients, and described their linkages to spillover occurrence over the past three decades.RESULTSThis integrated approach effectively improved the model's predictive and explanatory power. Our analysis reveals that the intermediate levels of human pressure facilitated the zoonotic spillover. The indirect effects of anthropogenic pressure, mediated by specific cropping intensity, are strongly associated with zoonoses emergence. Livestock distribution serves as an indicator of spillover hotspots, acting as effective proxies for distinctive landscapes.DISCUSSIONOur findings identify high zoonotic spillover risks present across geographically and socioeconomically diverse regions worldwide, extending beyond tropical areas, including extensive regions experiencing high-intensity human modification.

With many existing statistical methods and emerging approaches, it is important for practitioners to understand which method is best suited for their inferential goals.OBJECTIVEThe goal of this paper is to provide empirical simulation-based evidence regarding performance of mixture methods to help guide researchers on selecting the best available methods to address three scientific questions in mixtures analysis: identifying important components of a mixture, identifying interactions among mixture components and creating a summary score for risk stratification and prediction.METHODSWe conduct a review and comparison of 11 analytical methods available for use in mixtures research, through extensive simulation studies for continuous and binary outcomes. In addition, we carry out an illustrative data analysis using the PROTECT birth cohort from Puerto Rico, to examine the associations between exposure to chemical mixtures-metals, polycyclic aromatic hydrocarbons (PAHs), phthalates and phenols-and birth outcomes.RESULTSOur simulation results suggest that the choice of methods depends on the goal of analysis and there is no clear winner across the board. For selection of important toxicants in the mixtures and for identifying interactions, Elastic net by Zou et al.

However, most previous studies used single exposure rather than an exposome strategy to explore the association between environmental factors and fetal growth, and the interactions of environmental exposures with maternal and fetal genes were often overlooked.OBJECTIVESTo explore the associations between a broad range of prenatal environmental factors and fetal growth and further evaluate the effect modification of maternal and fetal T2D genetic susceptibility on the identified exposures.METHODSFrom 1,933 mother-neonate pairs from the Shanghai Birth Cohort, we estimated the associations between 70 prenatal exposure measures (including outdoor environment, residential environment, chemical exposures, lifestyle factors, and psychosocial status) and fetal growth, measured by birth-weight-for-gestational-age z-score (WAZ). Single-exposure analysis, elastic net regression, sparse partial least squares regression, extreme gradient boosting, and random forest were applied jointly to screen for WAZ-associated exposures. Multivariable linear regression models were used to assess the interactions of WAZ-associated exposures with maternal and fetal T2D polygenetic risk score (PRS).RESULTSSixteen prenatal exposures were associated with fetal growth, of which manganese, strontium, and residential greenspace showed a positive association while bisphenol A (BPA), 2,4-dihydroxy benzophenone (BP-1), ethyl 4-hydroxybenzoate (EtP), 4-hydroxybenzophenone (4-HBP), artificial light at night, noise, nitrogen dioxide, rubidium, thallium, silver, and humidity had a negative association.

Sucralose's high stability and resistance to degradation during wastewater treatment raises concerns about its long-term environmental and health impacts. Whether sucralose consumption correlates with reduced reproductive hormone levels and testicular damage remains unclear, and the underlying mechanisms require further investigation.OBJECTIVESThis study aims to investigate the influence of sucralose on cell damage and reproductive health in male.METHODSThe male mouse Leydig cell line TM3 and Sertoli cell line TM4 were used to evaluate sucralose-associated cellular damage. In vitro experiments assessed cell survival rates and the potential disruption of autophagy. Additionally, male SD rats were exposed to sucralose via oral gavage for two months at doses reflecting the acceptable daily intake (ADI) to evaluate sperm viability and reproductive health.RESULTSIn vitro experiments demonstrated cells exposed to sucralose had significantly lower cell survival rates. Sucralose exposure significantly reduced cell viability in TM3 and TM4 cells, induced oxidative stress, and disrupted autophagic flux by impairing autophagosome-lysosome fusion. Additionally, sucralose downregulated T1R3 protein expression, suggesting a role for sweet taste receptor signaling in testicular cell regulation. In vivo, chronic oral exposure to sucralose led to decreased sperm viability and dysregulated reproductive function, including altered testicular morphology and suppressed steroidogenesis.DISCUSSIONThese findings provide new insights into the adverse effects of sucralose on male reproductive physiology, highlighting its role in disrupting autophagy, inducing oxidative stress, and impairing reproductive function. The environmental persistence of sucralose and its potential leakage into wastewater systems present broader implications for public health and ecological stability. This study underscores the importance of carefully evaluating non-nutritive sweeteners in the diet and calls for stricter food safety regulations and wastewater management practices to mitigate potential risks.. https://doi.org/10.1289/EHP15919.","PeriodicalId":11862,"journal":{"name":"Environmental Health Perspectives","volume":"96 1","pages":""},"PeriodicalIF":10.4,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144066844","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
