Objective
To use data-driven approaches to investigate maternal multi-occupational exposures during pregnancy and their effects on intrauterine growth.
Methods
Maternal occupational exposure to 47 factors during pregnancy was evaluated with job-exposure matrices in the French ELFE cohort. The outcomes of interest were birthweight (BW), small for gestational age (SGA) and head circumference (HC). Occupational exposures associated with these outcomes were identified by EWAS, LASSO, and random forest. The five exposures with the strongest effects selected with these approaches were included in a final multivariate model with significant interactions.
Results
We included 12,851 women. The most important occupational factors predictive of SGA were endocrine disruptors, high strain, kneeling/squatting, job demands, physical effort. No significant associations were detected when these variables were combined in a final model. For BW, the most important variables were leaning forward/sideways, using a computer screen, ultrafine particles, physical effort, airborne germs, repetitive actions. The use of a computer screen significantly decreased BW and, for women not exposed to airborne germs, leaning forward/sideways significantly increased BW. For HC, repetitive actions, oxygenated solvents, kneeling/squatting, airborne germs, working outdoors were the most important predictive factors. Repetitive actions and working outdoors significantly decreased HC. HC also decreased in women exposed to both airborne germs, and oxygenated solvents. Similar results were found for women who worked during the third trimester.
Conclusion
Our findings highlight potential roles of chemical, biological and postural factors and their interactions in determining intrauterine growth. These results highlight the importance of considering multiple exposures in occupational health studies.

Antimony (Sb) is widely applied in industrial processes as well as in the manufacturing of consumer goods. The metalloid and many of its inorganic compounds can cause adverse health effects, with Antimony trioxide classified as possibly carcinogenic to humans (IARC group 2 B). In the German Environmental Survey for Children and Adolescents 2014–2017 (GerES V), a population-representative cross-sectional survey which combines questionnaire investigations and comprehensive human biomonitoring, the urine of 2250 children and adolescents aged 3–17 years was analysed for Sb.
Sb was detected in 79 % of the participants, with a geometric mean (GM) of 0.053 μg/L. Factors such as younger age, lower socioeconomic status (SES), number of smokers in the household, higher traffic intensity in the close vicinity of the home were significantly associated (p-value ≤0.05) with increased Sb levels in both bivariate and multivariable analyses. Compared to GerES IV (2003–2006), a decrease in Sb exposure of approximately 50 % was observed. However, assessing the health impact of our findings is challenging, particularly since Sb appears to play a key role in the joint effects of harmful metal mixtures.

Objective
Previous studies have suggested that perfluoroalkyl and polyfluoroalkyl substances (PFAS) could be related to the occurrence of miscarriages, but the results are inconclusive. Therefore, this study aimed to assess the effects of PFAS exposure during the first trimester on miscarriages that occurred between 12 and 22 weeks of gestation.
Methods
The participants were mothers and infants that registered for the Japan Environment and Children's Study. Twenty-eight PFAS, including perfluorooctanoic acid, perfluorohexane sulfonate, and perfluorooctane sulfonate, were identified in the plasma collected from pregnant participants. Miscarriage information was transcribed from the medical records. A propensity score was used to select the control group (mothers that gave live births), that matched the miscarriage group. The detection and concentrations of the PFAS in the miscarriage and control groups were compared.
Results
Among 24,412 pairs of maternal PFAS measurements, 66 miscarriages (0.3 %) were documented. No significant differences in the detections or concentrations of PFAS were found between the miscarriage and live birth groups (p > 0.196).
Conclusions
No association between prenatal PFAS exposure and late miscarriage was observed. Further studies are required owing to the small sample size.

Natural disasters have generally been associated with an increase in adverse birth outcomes, including preterm birth (PTB) and low birthweight (LBW) – two key markers of infant health that are predictive of infant mortality and life-long medical disabilities. However, there is considerable inconsistency between studies which makes it difficult to inform policy on pregnancy during and after natural disasters. In this study, we identify risk factors for pregnant women by undertaking the first meta-analysis on this topic, synthesising data from 42 studies with over 24 million participants. We also perform sub-group analysis on disaster type, a country's economic development, and trimester of exposure, addressing associations that can often not be examined in single studies. We found natural disasters to be associated with increased odds of both LBW (OR = 1.063) and PTB (OR = 1.075), with the largest effects seen from exposure in low Human Development Index countries (LBW: OR = 1.130; PTB: OR = 1.315), in first trimester (LBW: OR = 1.079; PTB: OR = 1.153), and following earthquake exposure for PTB (OR = 1.154). Our findings highlight the importance of directing disaster recovery efforts towards these vulnerable groups, to minimise the impacts on infant health following natural disasters.
自然灾害通常与不良出生结果的增加有关，包括早产（PTB）和低出生体重（LBW）——婴儿健康的两个关键标志，可预测婴儿死亡率和终身医疗残疾。然而，研究之间存在相当大的不一致性，这使得在自然灾害期间和之后为有关怀孕的政策提供信息变得困难。在这项研究中，我们通过对这一主题进行首次荟萃分析，综合了42项研究的数据，超过2400万参与者，确定了孕妇的危险因素。我们还对灾害类型、一个国家的经济发展和暴露的三个月进行了分组分析，解决了通常无法在单一研究中检查的关联。我们发现自然灾害与LBW （OR = 1.063）和PTB （OR = 1.075）的几率增加有关，在人类发展指数较低的国家（LBW: OR = 1.130; PTB: OR = 1.315）、妊娠早期（LBW: OR = 1.079; PTB: OR = 1.153）和地震后暴露于PTB （OR = 1.154）的影响最大。我们的研究结果强调了将灾难恢复工作导向这些弱势群体的重要性，以尽量减少自然灾害对婴儿健康的影响。

Pesticide exposure has been linked to chronic health harms, yet the effects of cumulative dietary exposure to pesticide mixtures are poorly understood. A pesticide load index was created to rank produce based on pesticide contamination from national pesticide residue testing data for 44 produce types, primarily collected from 2013 to 2018. Three indices were created utilizing different indicators of pesticide contamination and toxicity. Dietary pesticide exposure scores for 1837 individuals were calculated based on produce consumption from the 2015–2016 National Health and Nutrition Examination Survey (NHANES). Covariate-adjusted weighted linear regressions were used to estimate the change in average pesticide biomarker rank relative to dietary pesticide exposure scores. Pesticide load indices were calculated based on detections of 178 unique parent pesticides, or 42 parent pesticides with matched urinary biomarkers in NHANES. Increasing dietary pesticide exposure scores were not associated with average pesticide biomarker rank (β [95 % CI] = 0.02 [-0.34, 0.38]) and were consistent across scores that utilized the different indices. Matching pesticides in food and urine, results in a slightly stronger association (β [95 % CI] = 0.09 [-0.32, 0.51]). Excluding potatoes resulted in a positive significant association (β [95 % CI] = 0.75 [0.35, 1.14]). When excluding potatoes, consumption of fruits and vegetables weighted by pesticide contamination was associated with higher levels of urinary pesticide biomarkers for organophosphate, pyrethroid, and neonicotinoid insecticides. Future research could use this methodology, with the recommendation to exclude potatoes, to assess the impact of dietary pesticide exposure on health outcomes.

Due to the adverse health effects reported for several phthalate plasticizers, many phthalates have been increasingly replaced with alternatives in various consumer applications. In this study, we employed urine samples collected from the nationally representative populations of 2010 (n = 785) and 2018 (n = 799) and measured metabolites (n = 37) of major phthalate and non-phthalate plasticizers. Exposure levels of phthalates and non-phthalate plasticizers were compared, and their associated risks were assessed. Over the period, on average, urinary metabolite concentrations of major phthalates like DEHP and DBP decreased by 26 % and 31 %, respectively. In contrast, urinary metabolites of DEHTP and DEHA increased by 2131 % and 33 %, respectively. Metabolite profiles varied by age group, with DEHTP showing the highest levels among infants and children. Urinary metabolite concentrations of conventional phthalates showed the least reduction, and those of non-phthalate plasticizers exhibited the greatest increases during this period. Despite regulatory efforts against the use of several phthalates, the estimated daily intake (EDI) for all plasticizers has doubled among infants and children during this period, with DEHA being identified as a major contributor. Overall risk estimated based on anti-androgenicity decreased between 2010 and 2018, but DEHP and DBP remained significant risk drivers despite regulations during this period. Further research on exposure sources is warranted to inform measures that reduce exposure to plasticizers among the vulnerable populations identified in the present study.

The recent study by Ricau et al. (2025) provides timely evidence on the limited effectiveness of bioadditives for fecal sludge management (FSM) in informal settlements in Lebanon. Despite high hopes, Sanipit® did not significantly reduce sludge accumulation or E coli concentrations. This commentary emphasizes the need to reconsider sanitation strategies in humanitarian contexts, highlighting systemic, infrastructural, and governance factors beyond technical interventions. It proposes a shift from technocentric solutions toward resilient infrastructure, context-aware system design, and participatory governance. Case studies from other humanitarian crises further illustrate the limitations of purely technological interventions under fragile conditions. Reorienting sanitation research toward contextual realism and infrastructure resilience is essential for sustainable outcomes.

The misuse and overuse of antimicrobials drive the emergence of antimicrobial resistance (AMR), a critical global health concern. While wastewater treatment plants (WWTPs) are essential for removing microorganisms and contaminants, they also serve as hotspots for antibiotic-resistant bacteria (ARB) and antimicrobial resistance genes (ARGs), facilitating their persistence and dissemination.
This study investigated AMR in two WWTPs and one drinking water treatment plant (DWTP) in the Baix Llobregat area of Barcelona, Spain. Four sampling campaigns were conducted during winter and summer 2023 across different treatment stages. Due to drought conditions, reclaimed water from the Baix Llobregat WWTP was discharged upstream of the DWTP intake to supplement water resources for indirect potable reuse.
A total of 991 cultivable ARB were obtained, enabling phenotypic and genotypic characterisation. The most prevalent included Aeromonas spp. (44.3 %), Enterobacterales (27.9 %), Pseudomonas spp. (19.1 %), Acinetobacter spp. (4.8 %), Shewanella spp. (2.2 %), Stenotrophomonas spp. (1 %), and others (0.7 %). Among these, 57.3 % were multidrug-resistant and 2.7 % were extensively drug-resistant. Furthermore, 34.6 % produced extended-spectrum beta-lactamases, 14.1 % harboured carbapenemase genes, and 2.9 % exhibited colistin resistance.
Shotgun metagenomic analysis revealed high taxonomic diversity, without dominant genera across treatment stages. The resistome was dominated by ARGs conferring resistance to beta-lactams, aminoglycosides, and macrolides, alongside genes linked to biocide resistance and heavy metal tolerance. Spearman correlation analysis of selected sequenced strains suggested a weak to moderate co-occurrence between ARGs and biocide or heavy metal tolerance genes.
These findings underline WWTPs as AMR hotspots and reinforce the need to monitor DWTP source water within the One Health framework.

<div><h3>Objective</h3><div>To evaluate the potential association between essential metal elements and gestational diabetes mellitus (GDM), and to explore whether inflammatory indicators play an intermediary role in the association between essential metal elements and GDM.</div></div><div><h3>Methods</h3><div>This study included 4833 pregnant women who underwent early pregnancy examinations at Guangdong Women and Children Hospital between 2015 and 2022. Basic demographic information and peripheral blood samples were collected. Atomic absorption spectrometry was utilized to measure five essential metal elements, including iron (Fe), calcium (Ca), zinc (Zn), copper (Cu), and magnesium (Mg) in whole blood samples of pregnant women. Routine blood tests, including white blood cell (WBC), lymphocyte (Lym), neutrophil (Neu), monocyte (Mono), and platelet (PLT), were conducted using an automated hematology analyzer. The generalized linear regression model (GLM) was employed to analyze the relationship between essential metal elements, inflammatory indicators, and GDM. Mediation analysis was used to explore the potential mediating role of inflammatory indicators in the association between essential metal elements and GDM.</div></div><div><h3>Results</h3><div>Fe was positively correlated with WBC, NEU, LYM and MONO levels, and negatively correlated with PLT levels (<em>P</em> < 0.05).

Zn was positively correlated with WBC, NEU, LYM and PLT levels (<em>P</em> < 0.05). Cu was positively correlated with WBC, NEU and PLT levels (<em>P</em> < 0.05). Mg was positively correlated with WBC, NEU, LYM, MONO and PLT levels (<em>P</em> < 0.05). Compared with the first quantile concentration level, the fourth quantile level of Fe (<em>OR</em> = 1.282, 95 %<em>CI</em>: 1.043–1.578) and the fourth quantile level of Zn (<em>OR</em> = 1.267, 95 %<em>CI</em>: 1.032–1.559) were significantly positively correlated with GDM.
