Background: Phthalates exposure might cause kidney damage and a potential risk for hyperuricemia. However, direct evidence on phthalates and hyperuricemia is somewhat limited.
Objective: To examine associations between 10 phthalates metabolites and hyperuricemia in a large-scale representative of the U.S.
Methods: A cross-sectional study of 6865 participants aged over 20 from NHANES 2007-2016 was performed. All participants had complete data on ten phthalate metabolites (MECPP, MnBP, MEHHP, MEOHP, MiBP, cx-MiNP, MCOP, MCPP, MEP, MBzP), hyperuricemia, and covariates. We used multivariable logistics regression, restricted cubic splines (RCS) model, and Bayesian kernel machine regression (BKMR) models to assess single, nonlinear, and mixed relationships between phthalate metabolites and hyperuricemia. As a complement, we also assessed the relationship between phthalate metabolites and serum uric acid (SUA) levels.
Results: The multivariable logistics regression showed that MECPP, MEOHP, MEHHP, MBzP, and MiBP were generally positively associated with hyperuricemia (P < 0.05), especially in MiBP (Q3 (OR (95 %): 1.31 (1.02, 1.68)) and Q4 (OR (95 %): 1.68 (1.27, 2.24)), compared to Q1). All ten phthalate metabolites had a linear dose-response relationship with hyperuricemia in the RCS model (P for non-linear >0.05). BKMR showed that mixed phthalate metabolites were associated with a higher risk of hyperuricemia, with MBzP contributing the most (groupPIP = 0.999, condPIP = 1.000). We observed the consistent results between phthalate metabolites and SUA levels in three statistical models. The relationship between phthalate metabolites and hyperuricemia remained in the sensitivity analysis.
Conclusions: The present study suggests that exposure to phthalates, individually or jointly, might increase the risk of hyperuricemia. Since hyperuricemia influences on the quality of life, more explorations are needed to confirm these findings.

This study aimed to investigate the protective mechanism of Osmanthus fragrans water extract (OSF) against liver injury induced by dibutyl phthalate (DBP). We utilized liver organoids and liver organ chip technology to replicate the liver microenvironment in vivo. Metabolomic analysis revealed that DBP induced oxidative stress and lipid metabolism disorders; however, following intervention with OSF, the associated abnormal metabolites were significantly reduced.

Background: The emergence of drug-resistant pathogens has stimulated the need for the development of new antimicrobial agents. Epigenetic modulation by suppressing epigenetic inhibitors, such as 5-azacytidine (5-aza), has been shown to activate silent biosynthetic gene clusters within a fungus and causes the production of novel secondary metabolites. This research examined this epigenetic modification strategy in the poorly studied filamentous fungus, Ceratorhiza hydrophila, which may help induce the additional production of bioactive compounds.

Exposure to air pollution plays a significant role in human health. Current methods of measuring human exposure are often limited to outdoor measurements, are time intensive, or are unable to accurately measure certain classes of compounds. This study proposes human hair as a promising indicator of pollution exposure.

Background: Prenatal exposure to per- and polyfluoroalkyl substances (PFAS) may influence lung and immune system development, but previous epidemiological studies are inconclusive and have not extended into young adulthood.
Objective: To examine associations between prenatal exposure to a mixture of PFAS and respiratory and immune-related outcomes in a cohort of males.
Methods: We studied 866 males with maternal pregnancy plasma measured for 15 PFAS, triclosan, and nine phthalate metabolites used as a proxy for prenatal exposure.

Background/objectives: Phthalates are a group of ubiquitous environmental endocrine disruptors that can be detected in human body and exert adverse effects on reproductive health. We aimed to explore the correlation of phthalate exposure with polycystic ovary syndrome (PCOS).
Methods: We included 420 females who underwent assisted reproductive technology (ART) treatments between 2015 and 2018 in Jiangsu, China, comprising 94 PCOS cases and 326 controls.
