Acrylamide exposure, sex hormones, and pubertal status in Japanese adolescents
Nagata et al.
The finding, in our words
The study found that levels of an acrylamide metabolite in first-void urine were significantly and inversely associated with testosterone, puberty stage and facial hair growth in boys aged 13 to 14, but not in girls, suggesting that acrylamide exposure may disrupt pubertal development in males through effects on testosterone.
A paraphrase to the Library’s standard, never the abstract. The source is one link away and is always the authority.
First-void urine samples from 85 Austrian school children aged six to ten showed frequent low-level exposure to mycotoxins and phytoestrogens, with 22 percent exceeding the tolerable daily intake for deoxynivalenol and some facing possible health risks from ochratoxin A. The results support urine microsampling for decentralised exposome monitoring in paediatric populations.
Glyphosate was quantifiable in 99.8% of first-void urine samples from 6848 French adults and children, with higher levels in men and children and lower levels associated with organic food intake and filtered water; occupational exposure was higher in farmers, indicating widespread environmental contamination relevant to decentralised exposure monitoring.
The study found that higher urinary levels of certain pesticide metabolites were significantly associated with increased risk of acute lower and upper respiratory infections in children under five, particularly in those older than two years. This supports the use of decentralised urine microsampling for environmental exposure and child health studies.
In a French mother-child cohort, childhood exposure to pyrethroid insecticides, measured in first-void urine, was associated with reduced verbal comprehension scores at age six, while prenatal exposure showed no consistent association. This illustrates how urine biomarker monitoring in pediatric populations can identify environmental neurotoxicant risks.
The authors found that a single microdose of recombinant EPO was detectable up to 72 hours using ITP and CP methods, though the Tasso microsampling device showed lower sensitivity than Mitra and Capitainer. Additionally, isotope ratio mass spectrometry successfully detected testosterone micro-dosing in all analysed samples, supported by serum testosterone levels.
