Weight loss relapse associated with exposure to perfluoroalkylate substances
Science
17 Apr 2023 | Obesity
PFOA and PFHxS plasma concentrations were associated with increased weight gain, meaning obesogenic PFAS may cause weight gain and thus contribute to the obesity pandemic.

PFAS: forever chemicals—persistent, bioaccumulative and mobile. Reviewing the status and the need for their phase out and remediation of contaminated sites
Science
23 Mar 2023 | ESEU
The authors of this review conclude that substituting individual PFAS recognized as hazardous with other possibly equally hazardous PFAS with virtually unknown chronic toxicity should not be a solution.

Association between polyfluoroalkyl substances exposure and sex steroids in adolescents: The mediating role of serum albumin
Science
27 Feb 2023 | Ecotoxicol Environ Saf
Mixed exposure to PFAS was associated with endocrine disruption in developing adolescents, especially in girls, and serum albumin was found to play a possible mediating role in this association.

Exposure to serum perfluoroalkyl substances and biomarkers of liver function: The Korean national environmental health survey 2015-2017
Science
21 Feb 2023 | Chemosphere
Higher serum PFOA, PFOS, PFHxS, PFDA, and PFNA concentrations were related to higher serum concentrations of liver enzymes, although some differences were dependent on sex and obesity status.

Association of per-and polyfluoroalkyl substance exposure with fatty liver disease risk in US adults
Science
2 Feb 2023 | JHEP Rep.
Higher serum PFAS was moderately associated with decreased liver function in the general population, especially in those with independent risk factors such as heavy alcohol intake, obesity, or high-fat diets.

Red blood cell folate modifies the association between serum per- and polyfluoroalkyl substances and antibody concentrations in U.S. adolescents
Science
30 Jan 2023 | Environ. Sci. Technol.
Associations between higher serum PFAS and lower disease antibodies were found to be significant only in adolescent groups with lower folate levels, suggesting that folate may be used as a mitigation measure against immune-related PFAS effects.

Occurrence and implications of per and polyfluoroalkyl substances in animal feeds used in laboratory toxicity testing
Science
10 Jan 2023 | Sci Total Environ
PFAS contamination in animal feed was found to be pervasive, which is significant because unintended PFAS exposure in control animals from feed can significantly bias toxicity testing.
