Liu X, Xiang Q, Zhang L, Li J, Wu Y. Occurrence of rare earth elements in umbilical cord serum and association with thyroid hormones and birth outcomes in newborns. CHEMOSPHERE 2024; 359:142321. [PMID: 38754495 DOI: 10.1016/j.chemosphere.2024.142321] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/20/2023] [Revised: 04/13/2024] [Accepted: 05/10/2024] [Indexed: 05/18/2024]
Abstract
Rare earth elements (REEs) are emerging contaminants that are increasingly used in high technology products. However, limited information is available regarding exposure to REEs and associated health effects in neonates. This study aimed to investigate the association between REE concentrations and thyroid hormone levels, as well as birth outcomes in 109 newborns in Beijing, China. We measured the concentrations of 16 REEs and thyroid hormones in umbilical cord serum. To assess the impact of exposure to individual REEs and REE mixtures on thyroid hormone levels and birth outcomes, we employed univariate linear regression, least absolute shrinkage and selection operator (LASSO), and weighted quantile sum (WQS) models. We detected 14 REEs at high rates (92.6%-100%), with yttrium exhibiting the highest median (interquartile range) concentration [43.94 (0.33-172.55) ng/mL], followed by scandium [3.64 (0.46-11.15) ng/mL]. Univariate analyses showed that per logarithmic (ln)-unit change of neodymium (Nd) and samarium (Sm) was associated with 0.039 [95% confidence interval (CI): 0.001, 0.007] and 0.031 (95% CI: 0.003, 0.060) increases in free thyroxine (FT4) levels, respectively. Moreover, 14 REEs exhibited significant associations with triiodothyronine (T3) levels, resulting in increases ranging from 0.066 to 0.307. Elevated concentrations of terbium (Tb) [per ln-unit change: -0.021 (95% CI: -0.041, -0.01)] and lutetium (Lu) [-0.023 (95% CI: -0.043, -0.002)] were inversely correlated with birth length in newborns. A further multiple exposure analysis employing the LASSO model identified Sm, Nd, Y, Sc, and Lu as critical factors influencing FT4 and T3 levels. Additionally, WQS analyses showed positive associations between exposure to a mixture of 14 REEs and FT4 (P = 0.046), T3 (P < 0.001), and birth length (P = 0.049). These findings suggest that in utero exposure to REEs might disrupt thyroid hormone homeostasis and impact intrauterine growth. Further studies are warranted to validate these findings and elucidate the underlying mechanisms.

Abstract
Background: Malnutrition in early life may permanently change the structure and function of the body, which lead to a number of diseases in adulthood. The effect of famine exposure during the early life on thyroid function and disorders remains unclear. This study investigated the association between exposure to the Great Chinese Famine (1959-1961) in early life and thyroid function and disorders in adulthood. Methods: Nine thousand eight hundred eighty-one subjects with appropriate birth dates derived from the Thyroid disorders, Iodine status, and Diabetes Epidemiological survey were included. Thyroid function and disorders were defined by the test results of blood sample and ultrasonography of all participants. Associations between famine exposure in early life and thyroid function and disorders in adulthood were assessed with binary logistic regression and linear regression. Results: Participants exposed to the Great Chinese Famine during the fetal stage was associated with a higher thyrotropin (TSH) level in adulthood (β = 0.024; p = 0.038), compared with the nonexposed participants. The association was significant among rural participants (β = 0.039; p = 0.02) but not in urban participants (β = 0.005; p = 0.77). Fetal-exposed group did not show a higher risk of thyroid disorders than the age-matched balanced control group, including overt hyperthyroidism, subclinical hyperthyroidism, overt hypothyroidism, subclinical hypothyroidism, autoimmune thyroiditis, and thyroid nodules (p > 0.05). Conclusions: Famine exposure during the fetal stage was associated with a higher TSH level in adulthood. The fetal stage could be the critical period for programming the pituitary-thyroid axis.

Prenatal exposure of rare earth elements cerium and ytterbium and neonatal thyroid stimulating hormone levels: Findings from a birth cohort study. ENVIRONMENT INTERNATIONAL 2019; 133:105222. [PMID: 31655275 DOI: 10.1016/j.envint.2019.105222] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/18/2019] [Revised: 08/17/2019] [Accepted: 09/24/2019] [Indexed: 05/23/2023]
Abstract
BACKGROUND Prior studies have suggested exposure to heavy metals and endocrine disrupting chemicals could disturb the homeostasis of thyroid stimulating hormone (TSH), but no epidemiology study concerning the influence of rare earth elements (REE) exposure during pregnancy on neonatal TSH levels. The present study aimed to investigate the relationships between prenatal REE exposure and neonatal TSH levels. METHODS A total of 7367 pregnant women were recruited from Wuhan Children's Hospital between September 2012 and October 2014 in Wuhan, China. Urinary concentrations of cerium (Ce), and ytterbium (Yb) were measured by inductively coupled plasma mass spectrometry (ICP-MS). Immunofluorescence assay was used to detect neonatal TSH levels. The associations between REE exposure and neonatal TSH levels were evaluated using multivariate linear regression models. RESULTS The geometric means of maternal urinary Ce and Yb concentrations were 0.060 μg/g creatinine and 0.025 μg/g creatinine, respectively. The results showed that per doubling of maternal urinary Ce and Yb were associated with 4.07% (95% CI: -5.80%, -2.31%), 5.13% (95% CI: -6.93%, -3.30%) decreased neonatal TSH levels respectively in the adjusted model. Sex stratified analysis demonstrated that the decreased neonatal TSH levels were observed both in male infants and female infants, and the decrease was greater in male infants in urinary Ce. There were no significant interactions between maternal urinary Ce, Yb and infant sex (Ce: P for interaction = 0.173, Yb: P for interaction = 0.967). CONCLUSIONS Our findings demonstrated that increased maternal urinary Ce and Yb were associated with decreased neonatal TSH levels. Further researches from different populations are warranted to verify the association and to explore the mechanisms.
