Early childhood exposures to phthalates in association with attention-deficit/hyperactivity disorder behaviors in middle childhood and adolescence in the ReCHARGE study. Int J Hyg Environ Health 2024; 259:114377. [PMID: 38692176 DOI: 10.1016/j.ijheh.2024.114377] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2024] [Revised: 03/19/2024] [Accepted: 03/31/2024] [Indexed: 05/03/2024]
Abstract
BACKGROUND Early-life exposure to phthalates alters behaviors in animals. However, epidemiological evidence on childhood phthalate exposure and attention-deficit/hyperactivity disorder (ADHD) behaviors is limited. METHODS This study included 243 children from the ReCHARGE (Revisiting Childhood Autism Risks from Genetics and Environment) study, who were previously classified as having autism spectrum disorder (ASD), developmental delay, other early concerns, and typical development in the CHARGE case-control study. Twenty phthalate metabolites were measured in spot urine samples collected from children aged 2-5 years. Parents reported on children's ADHD symptoms at ages 8-18 years using Conners-3 Parent Rating Scale. Covariate-adjusted negative binomial generalized linear models were used to investigate associations between individual phthalate metabolite concentrations and raw scores. Weighted quantile sum (WQS) regression with repeated holdout validation was used to examine mixture effects of phthalate metabolites on behavioral scores. Effect modification by child sex was evaluated. RESULTS Among 12 phthalate metabolites detected in >75% of the samples, higher mono-2-heptyl phthalate (MHPP) was associated with higher scores on Inattentive (β per doubling = 0.05, 95% confidence interval [CI]: 0.02, 0.08) and Hyperactive/Impulsive scales (β = 0.04, 95% CI: 0.00, 0.07), especially among children with ASD. Higher mono-carboxy isooctyl phthalate (MCiOP) was associated with higher Hyperactivity/Impulsivity scores (β = 0.07, 95% CI: -0.01, 0.15), especially among typically developing children. The associations of the molar sum of high molecular weight (HMW) phthalate metabolites and a phthalate metabolite mixture with Hyperactivity/Impulsivity scores were modified by sex, showing more pronounced adverse associations among females. CONCLUSION Exposure to phthalates during early childhood may impact ADHD behaviors in middle childhood and adolescence, particularly among females. Although our findings may not be broadly generalizable due to the diverse diagnostic profiles within our study population, our robust findings on sex-specific associations warrant further investigations.

A co-twin control study of in utero exposure to poly- and perfluoroalkyl substances and associations with neonatal thyroid-stimulating hormone. ENVIRONMENTAL RESEARCH 2023; 239:117350. [PMID: 37821063 DOI: 10.1016/j.envres.2023.117350] [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: 05/31/2023] [Revised: 10/06/2023] [Accepted: 10/07/2023] [Indexed: 10/13/2023]
Abstract
Research quantifying associations between early-life exposure to poly- and perfluoroalkyl substances (PFAS) and neonatal thyroid hormone levels is limited and reports inconsistent results. This study aimed to examine the associations of in utero PFAS exposure with neonatal thyroid-stimulating hormone (TSH), and to verify whether genetic and familial factors contribute to these associations. Within Wuhan Twin Birth Cohort study, we included 148 mother-twin pairs recruited between March 2016 and January 2018. Maternal plasma PFAS concentrations were measured at three different trimesters and averaged. Additionally, we measured cord plasma PFAS concentrations for twin newborns and retrieved their TSH levels from the medical system. Multivariable linear regression, generalized estimation equation, and linear mixed models were used to examine the covariate-adjusted associations. For maternal PFAS analyses, a 2-fold increment of average maternal perfluorooctanoic acid (PFOA) and perfluorodecanoic acid (PFDA) concentrations was linked with a 15% (95% CI: 2.5%, 28%) and 14% (95% CI: 2.4%, 28%) increase in neonatal TSH, respectively. For twin newborns discordant for PFAS exposure, a 2-fold increment of cord plasma PFOA, PFDA, perfluoroundecanoic acid (PFUdA), and perfluorohexanesulfonic acid (PFHxS) concentrations was related to a 7.1% (95% CI: 0.31%, 14%), 12% (95% CI: 4.8%, 20%), 7.5% (95% CI: 0.30%, 15%), and 8.5% (95% CI: 3.0%, 14%) increase in TSH among twins as individuals, respectively. Although these associations were mainly observed between twin pairs, certain PFAS exposure might have an independent association with increased TSH. Our present study suggests that higher maternal and cord plasma PFAS concentrations are associated with increased neonatal TSH, and genetic and familial factors contribute to these associations.

Abstract
CONTEXT Patients with congenital hypothyroidism (CH) are affected more often than the general population by other chronic diseases and neurological difficulties. OBJECTIVE The aim of this nationwide population-based register study was to investigate the incidence of congenital malformations, comorbidities, and the use of prescribed drugs in patients with primary CH. METHODS The study cohort and matched controls were identified from national population-based registers in Finland. All diagnoses from birth until the end of 2018 were collected from the Care Register, and subject-specific prescription drug purchases were identified from The Prescription Register from birth until the end of 2017. RESULTS Diagnoses of neonatal and chronic diseases were collected for 438 full-term patients and 835 controls (median follow-up time 11.6 years; range, 0-23 years). Newborns with CH were more often found to have neonatal jaundice (11.2% and 2.0%; P < .001), hypoglycemia (8.9% and 2.8%; P < .001), metabolic acidemia (3.2% and 1.1%; P = .007), and respiratory distress (3.9% and 1.3%; P < .003) as compared to their matched controls.Congenital malformations were diagnosed in 66 of 438 (15.1%) CH patients and in 62 of 835 (7.4%) controls (P < .001). The most commonly affected extrathyroidal systems were the circulatory and musculoskeletal systems. The cumulative incidence of hearing loss and specific developmental disorders was higher among CH patients than controls. The use of antidepressant and antipsychotic drugs was similar in CH patients and their controls. CONCLUSION CH patients have more neonatal morbidity and congenital malformations than their matched controls. The cumulative incidence of neurological disorders is higher in CH patients. However, our results do not support the existence of severe psychiatric comorbidity.

ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2023; 250:114502. [PMID: 36603489 DOI: 10.1016/j.ecoenv.2023.114502] [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: 09/22/2022] [Revised: 12/27/2022] [Accepted: 01/02/2023] [Indexed: 06/17/2023]
Abstract
Thyroid hormones are essential for fetal growth and neurodevelopment. The recent frequent use of parabens has raised concerns about their endocrine-disrupting potential. However, the effects of maternal paraben exposure on neonatal thyroid hormone levels are still largely unknown. In our study, a co-twin control design was employed to analyze the relationships between maternal paraben exposure and neonatal thyroid-stimulating hormone (TSH) difference. We collected information from 252 mother-twin pairs from a twin birth cohort in Wuhan, China. Concentrations of six parabens were measured in maternal urine samples collected at < 16, 16-28, and > 28 weeks of gestation. Data of neonatal TSH levels were retrieved from medical records. Multiple informant models were applied to explore the time-specific relationships between paraben exposure and intra-twin TSH difference and to determine the susceptible window of exposure. We found that maternal urinary methyl paraben (MeP) during early pregnancy was positively associated with intra-twin TSH difference (%change = 5.96 %; 95 % confidant interval (CI): 0.04 %, 12.2 %). However, no significant differences were observed for exposure to ethyl paraben (EtP) and propyl paraben (PrP), and the associations between parabens and intra-twin TSH difference did not differ materially across pregnancy. Further, a stratified analysis based on twin zygosity and chorionicity and sex types indicated that the positive association between early pregnancy MeP exposure and intra-twin TSH difference was significant in monochorionic diamniotic (MCDA) twins of female-female fetuses and dichorionic diamniotic (DCDA) twins of opposite-sex. The prospective twin study provides first evidence that MeP exposure in early pregnancy was associated with an increased TSH difference in twin neonates, especially in female fetuses.

Abstract
CONTEXT Hysterosalpingography (HSG) using oil-soluble contrast medium (OSCM) improves pregnancy rates but results in severe and persistent iodine excess, potentially impacting the fetus and neonate. OBJECTIVE To determine the incidence of thyroid dysfunction in newborns conceived within six months of OSCM HSG. DESIGN Offspring study of a prospective cohort of women who underwent OSCM HSG. SETTING Auckland region, New Zealand (2020-2022). PARTICIPANTS Offspring from the SELFI (Safety and Efficacy of Lipiodol in Fertility Investigations) study cohort (n=57). MEASUREMENTS All newborns had a dried blood spot card for TSH measurement 48 hours after birth as part of New Zealand's Newborn Metabolic Screening Programme. Forty-one neonates also had a heel prick serum sample at one week to measure thyroid-stimulating hormone (TSH), free thyroxine (FT4), and free triiodothyronine (FT3). Maternal urine iodine concentration (UIC) and TSH in the six months after OSCM HSG were retrieved from the SELFI study for analyses. PRIMARY OUTCOME Incidence of hypothyroidism in the neonatal period. RESULTS There was no evidence of primary hypothyroidism on newborn screening (TSH 2-10 mIU/L). All neonates tested at one week had normal serum TSH, FT4, and FT3 levels. However, increasing maternal peak UIC levels during pregnancy were associated with lower TSH levels (p= 0.006), although also associated with lower FT4 levels (p=0.032). CONCLUSIONS While pre-conceptional OSCM HSG in women did not result in neonatal hypothyroidism, gestational iodine excess was associated with a paradoxical lowering of neonatal TSH levels despite lower FT4 levels. These changes likely reflect alterations in deiodinase activity in the fetal hypothalamic-pituitary axis from iodine excess.

Abstract
AIM Recently, there has been debate about reducing newborn screening (NBS) thyroid-stimulating hormone (TSH) cut-offs to identify children with mild, but potentially clinically significant, thyroid deficiency. Once identified by NBS, these children will be referred to paediatric endocrinologists for further testing and possible treatment; however, variation in current clinical practice is not known. The aim of this study is to survey Paediatric Endocrinologists in Australia and New Zealand to gain insight into clinical practice for the treatment of mild thyroid deficiency. METHODS A piloted questionnaire was sent to members of the Australasian Paediatric Endocrinologist Group. The survey asked the Australasian Paediatric Endocrinologist Group members about the investigations performed, treatment and follow-up for infants with different confirmatory serum TSH levels. RESULTS There were 42 completed surveys, a response rate of 34%. When presented with four case studies, 7% of clinicians would treat a child with confirmatory serum TSH of 8.7 mU/L with thyroxine, 69% would treat a child with confirmatory serum TSH 21.4 mU/L, 76% would treat a child with confirmatory serum TSH 24.3 mU/L and 95% would treat a child with confirmatory serum TSH 44.7 mU/L. CONCLUSION This contemporary survey of clinicians regarding the treatment of mild thyroid deficiency in children has shown that clinical practice varies extensively. International and national guidelines on the treatment of congenital hypothyroidism should be updated to incorporate new evidence and ensure consistency across clinical practice.

Abstract
Newborn screening is an important public health program and a triumph of preventive medicine. Economic analyses show that the benefits of newborn screening clearly outweigh the costs for certain diseases, but not necessarily for other ones. This is due to the great diversity of the natural history of the diseases detected, to the fact that each of these diseases considered individually is rare, and to differences in the effectiveness of interventions. In addition, the benefit-cost ratio of screening for a particular disorder may differ between countries, specifically between high-income and low- and middle-income countries. The burden of a disorder may also be alleviated by increased clinical awareness and effective clinical services, even in the absence of newborn screening. In this article, we focus on economic analyses of newborn screening for primary congenital hypothyroidism, which has been in place in high-income countries for roughly 40 years, and for classic congenital adrenal hyperplasia due to 21-hydroxylase deficiency. Screening for the latter is not yet universal, even in high-income countries, although the lack of universal implementation may reflect factors other than economic considerations.
