The association between exposure to volatile organic compounds and serum lipids in the US adult population.

Background And Aim: Epidemiological evidence on the relationship between exposure to volatile organic compounds (VOCs), both single and mixed, and serum lipid levels is limited, and their relationship remains unclear. Our study aimed to investigate the associations of exposure to VOCs with serum lipid levels in the US adult population.

Methods And Results: The study examined the association of 16 VOC levels (2-methylhippuric acid, 3- and 4-methylhippuric acid, N-acetyl-S-(2-carbamoylethyl)-L-cysteine, N-acetyl-S-(N-methylcarbamoyl)-L-cysteine, 2-aminothiazoline-4-carboxylic acid, N-acetyl-S-(benzyl)-L-cysteine, N-acetyl-S-(n-propyl)-L-cysteine, N-acetyl-S-(2-carboxyethyl)-L-cysteine, N-acetyl-S-(2-cyanoethyl)-L-cysteine, N-acetyl-S-(3,4-dihydroxybutyl)-L-cysteine, N-acetyl-S-(2-hydroxypropyl)-L-cysteine.

The association between hearing threshold and urinary personal care and consumer product metabolites in middle-aged and elderly people from the USA.

Endocrine disruptors have been reported to be associated with hearing ability. However, the association between personal care and consumer product chemicals, known as commonly detected endocrine disruptors, and age-related hearing loss still remains unclear. This study aimed to examine the association between exposure to 7 personal care and consumer product chemicals and hearing thresholds in middle-aged and elderly people.

The bidirectional relationship between metabolic syndrome and hyperuricemia in China: A longitudinal study from CHARLS.

Objective: It has been reported that metabolic syndrome (MetS) has been associated with hyperuricemia. However, current findings have been inconclusive regarding the direction of this association. The objective of this study was to clarify the possible directional relationship between hyperuricemia and MetS.

The Association Between Dietary Inflammatory Index and Sex Hormones Among Postmenopausal Women in the US.

Aims: Diet has been found to have an important effect on sex hormones. The effect of diet-induced inflammation on sex hormones has not been studied in detail among women. Therefore, we aimed to investigate the association between energy-adjusted dietary inflammatory index (E-DII) and sex hormones among postmenopausal women.
