Background: Seasonality in the incidence of congenital hypothyroidism (CH) has been identified in several countries and different conclusions have been drawn. The objective of this study was to examine whether this seasonality is also observable in China and how it manifests across different temperate zones.
Methods: Data on CH cases and screened neonates between January 1, 2014, and September 30, 2022, by year and season, were sourced from the Chinese Newborn Screening Information System.

Background: Immediately after birth, adaptation to the extrauterine environment includes an upregulation of fatty acid catabolism. Cystic fibrosis and untreated hypothyroidism exert a life-long impact on fatty acid metabolism, but their influence during this transitional period is unknown. Children and adults with cystic fibrosis exhibit unbalanced fatty acid composition, most prominently a relative deficit of linoleic acid.

Background: Maternal hypertensive disorders of pregnancy (HDP) was associated with increased risk of congenital hypothyroidism in preterm infants, but its underlying mechanisms remain unclear.
Objective: To investigate the possible mechanisms by which intrauterine exposure to HDP affects thyroid hormone synthesis in preterm infant rats.
Methods: preterm infant rats were obtained by Caesarean section delivery from the L-NAME group and Control groups which was induced by L-NAME and saline, respectively.
