Introduction: Subclinical hypothyroidism (SH) is a biochemical condition characterized by serum levels of TSH above the reference range upper limit (4,5μUI/mL), with normal concentrations of thyroid hormones. In cases of non-autoimmune subclinical hypothyroidism (NASHT), genetic defects have been described and can determine disorders in the biosynthesis process of thyroid hormones, such as heterozygous mutations in the TSH receptor gene (TSHR) and ...

Preterm and low birth weight(LBW) newborns are at risk of thyroid dysfunction during a critical period for neurodevelpment and this dysfunction can be missed in congenital hypothyroidism screening program(CHSP). Consequently, reassessment of thyroid function has been promoted in neonatal units, added to CHSP.Objectives: To evaluate prevalence and risk factors of thyroid dysfunction in≤32weeksGA and/or 1500g newborn, and compare differ...
