In Shanghai, a new iodized salt standard was implemented in 2012. To provide evidence to the government, we compared iodine status before (35 mg/kg) and after (30 mg/kg) adjustment in vulnerable populations living in Shanghai. The probability-proportional-to-size sampling technique was used to select at least 360 pregnant women for urine iodine test and at least 1200 students for thyroid measurement and the household salt test. Of these students, at least 360 performed urine iodine test. The median thyroid volume and the median household salt iodine concentration of children aged 8-10 years were 1...

Inorganic nitrate (NO3 ) due to its potential endogenous conversion to nitric oxide (NO), is suggested as a compensatory fuel for disrupted NO pathways in the case of pathological stats during pregnancy. Dietary NO3 -rich supplement in the NO-deficient pregnant women is now suggested as a more appealing choice with fewer off-target effects which can attenuate hypertension and preeclampsia, improve placental blood flow and subsequently enhance maternal and neonatal health. There is also an increasing public interest and common health claims regarding beneficial effects of NO3 -rich dietary supplements like beetroot byproducts in pregnant women...

INTRODUCTION: Approximately 3% to 5% of pregnant women have hypothyroidism. Despite the potential impact of untreated hypothyroidism on infant neurodevelopment, few studies have investigated the risk factors associated with discontinuation of thyroid hormone replacement therapy (THRT) in pregnancy. We aimed to identify such factors in a population of women using THRT prior to pregnancy. MATERIAL AND METHODS: Data from the Norwegian Mother and Child Cohort Study were linked to records in the Medical Birth Registry of Norway...

Understanding how environmental and social factors affect reproduction through variation in energetic condition remains understudied in wild animals, in large part because accurately and repeatedly measuring energetic condition in the wild is a challenge. Thyroid hormones (THs), such as triiodothyronine (T3) and thyroxine (T4), have a key role in mitigating metabolic responses to energy intake and expenditure, and therefore are considered important biomarkers of an animal's energetic condition. Recent method development has shown that T3 and T4 metabolites can be measured in feces, but studies measuring THs in wild populations remain rare...

Thyroid hormones (TH) are essential for brain development, but there exists few rodent models that link TH insufficiency to apical neurodevelopmental endpoints. We have previously described a structural anomaly, a heterotopia, in the brains of rats treated in utero with propylthiouracil (PTU). However, how the timing of an exposure relates to this birth defect is unknown. This study seeks to understand how various temporal treatments of the mother relates to TH insufficiency and adverse neurodevelopment of the offspring...
