Endocrine disruptors are substances capable of altering the functions of the endocrine system. There is evidence that some pesticides can be endocrine disruptors and, among some of their effects, we find alterations in pubertal development and in the function of the thyroid gland, which could be related to a greater tendency of obesity. The aim was to evaluate the evidence from clinical and preclinical studies on the association between pesticides used in agriculture and found in plant-based foods with overweight/obesity.

Differentiated thyroid cancer (DTC) generally has a favorable prognosis, and radioactive iodine (RAI) therapy is typically used for metastatic DTC that continues to progress and poses life-threatening risks. However, resistance to RAI in metastatic DTC significantly impairs treatment effectiveness. This study aims to identify potential compounds that may influence RAI efficacy.

Electronic address:

Congenital hypothyroidism (CH) has been reported as a prevalent endocrine disorder in newborns. Endocrine disrupting chemicals (EDCs) have been widely detected in humans and can influence endocrine function, especially thyroid function, and neonates as a susceptible population may be more prone to suffer from CH through exposure to various EDCs. In this study, the concentrations and composition profiles of several typical EDCs were determined in 266 serum samples collected from newborns with (n = 136) and without CH (n = 130) in Beijing, China from 2018 to 2020.

Iodine is a trace element that is required to produce thyroid hormone. Some preoperative skin antiseptics and contrast media that are used in a variety of specialties (eg, cardiovascular, urology) contain iodine. Clinicians and patients may believe that a history of a reaction to shellfish, povidone-iodine, or radiopaque contrast media is an allergy requiring avoidance of all three substances.

Electronic address:

Background: Exposure to per- and polyfluoroalkyl substances (PFAS) may linked to thyroid cancer (TC) risk, but inconsistent findings and a lack of studies on mixed exposures exist, especially regarding novel PFAS compounds. Additionally, little is known about the potential mechanisms underlying the association.

Objectives: Explore the effects of PFAS exposure on the serum metabolome and its correlation with TC.
