Article Abstract
The longitudinal association between per- and polyfluoroalkyl substances (PFASs) and type 2 diabetes (T2D) remains elusive. We conducted a nested case-control study, including 985 incident diabetes cases and 985 matched controls to explore the association of PFASs exposure with T2D. Serum concentrations of 30 PFASs were measured. Odds ratios (ORs) were estimated by conditional logistic regression. PFAS mixtures effects were assessed using BKMR, WQSR, and Qgcomp. We assessed the roles of lifestyle score and polygenic risk score in PFASs-T2D association by multiplicative/additive interaction. PFOA and PFNA were positively associated, but L-PFHxS and L-PFOS were negatively associated with T2D. Compared with the extreme tertiles, the OR (95 % CI) was 1.39 (1.09-1.78) for PFOA; 1.32 (1.02-1.71) for PFNA; 0.77 (0.60-0.99) for L-PFHxS; 0.71 (0.55-0.92) for L-PFOS. PFBA and PFHpA (detected/not-detected) were positively associated with T2D. Positive associations of PFBA, PFOA, and PFNA with T2D were only observed in females, whereas negative associations of L-PFHxS and L-PFOS were observed in males. PFASs mixtures were not associated with T2D, but independent associations were found between PFOA, PFNA, L-PFHxS, and L-PFOS with T2D. Additive interactions were observed between PFASs exposure and lifestyle/genetic susceptibility. Poor lifestyle and genetic risk may amplify the adverse effects of PFASs.

Background: Although per- and polyfluoroalkyl substances (PFAS) have been linked to chronic liver diseases, the specific cellular and molecular mechanisms by which different PFAS contribute to human liver dysfunction remain unclear. This study aims to elucidate those mechanisms.
Methods: We exposed a multi-donor human liver spheroid model composed of multiple cell types to 20 µM of PFHxS, PFOA, PFOS, or PFNA for seven days, followed by single-cell RNA sequencing and lipid staining.

Background: Prenatal exposure to per- and polyfluoroalkyl substances (PFAS) may adversely impact child neurodevelopment; however, epidemiologic findings remain inconclusive because of small sample sizes, limited exposure variability, and differing neurodevelopmental measures. We aimed to investigate the relationship between prenatal PFAS exposure and child behavior.
Methods: We pooled data from nine study sites in the nationwide Environmental influences on Child Health Outcomes (ECHO) Cohort.

Background: Testicular germ cell cancer (TGCC) originates during fetal life. Fetal exposure to environmental chemicals may contribute to its development, but epidemiological data are lacking. We investigated per- and polyfluoroalkyl substances (PFAS), which can act as endocrine disruptors during fetal development, and TGCC risk in adulthood.

As there are a growing number of per- and polyfluoroalkyl substances (PFAS) alternative substitutes applied globally, it remains paramount to characterize their potential health risks. Perfluorodecanoic acid (PFDA) is the most common alternative PFAS detected in the environment; however, its toxic effects and underlying mechanism of action to aquatic biota remains unclear. In this study, we present evidence of PFDA-induced immunotoxicity and gain insight into underlying molecular mechanisms.
