REVIEW
Paolo Beck-Peccoz, Giulia Rodari, Claudia Giavoli, Andrea Lania
Central hypothyroidism is a rare and heterogeneous disorder that is characterized by a defect in thyroid hormone secretion in an otherwise normal thyroid gland due to insufficient stimulation by TSH. The disease results from the abnormal function of the pituitary gland, the hypothalamus, or both. Moreover, central hypothyroidism can be isolated or combined with other pituitary hormone deficiencies, which are mostly acquired and are rarely congenital. The clinical manifestations of central hypothyroidism are usually milder than those observed in primary hypothyroidism...

Epidemiological studies have shown that mid-arm circumference (MAC) can be used to predict death risk and malnutrition. We performed a retrospective observational study involving 11,958 US participants aged 20-90 years from the National Health and Nutrition Examination Survey III, 1988-1994, to determine the correlation between MAC and all-cause, cardiovascular, and cancer mortality risk in the obese and non-obese population. Death certificate data were obtained up to 2006. The participants were divided into three groups on the basis of body mass index: 19 ≤ BMI < 25 kg/m(2) (normal weight group), 25 ≤ BMI < 30 kg/m(2) (overweight group) and BMI ≥ 30 kg/m(2) (obesity group); each group was then divided into three subgroups depending on their MAC level...

BACKGROUND: Thyroid hormone (TH) acts via nuclear thyroid hormone receptors (TRs). TR isoforms (TRα1, TRα2, TRβ1, TRβ2) are encoded by distinct genes (THRA and THRB) and show differing tissue distributions. Patients with mutations in THRB, exhibiting resistance within the hypothalamic-pituitary-thyroid axis with elevated TH and nonsuppressed thyroid-stimulating hormone (TSH) levels, were first described decades ago. In 2012, the first patients with mutations in THRA were identified...

BACKGROUND: Abnormal thyroid hormone (TH) metabolism is significantly associated with impaired left ventricular (LV) function and death. Although TH was traditionally thought to be produced exclusively by the thyroid gland, an increasing number of studies report TH production in other tissues. Based on these findings, we evaluated whether the genes required for TH biosynthesis are expressed in the human heart, and whether their expression is altered in patients with ischemic cardiomyopathy (ICM) and is related to epigenetic variations...
