Objectives: Graves’ disease (GD) is a common cause of hyperthyroidism. An increased heart rate (HR) is a hallmark of elevated thyroid hormones (TH). In a prospective observational study we monitored HR continuously with wearable fitness trackers to evaluate the correlation between HR and TH levels and the relevance of HR monitoring for clinical management of patients with GD.Methods: Seventeen outpatients with newly diagnosed or relapsed GD starting...

Brown adipose tissue (BAT) may directly dissipate energy into heat and is associlated with a metabolically favorable phenotype. Cold exposure activates BAT via the sympathetic nervous system and its transmitter norepinephrine. In rodents, the activation is facilitated by the β3-adrenoreceptor (β3-AR). In humans treatment with the β3-AR agonist mirabegon leads to a rather weak activation of BAT as compared to a cold stimulus. In vitro studies in cell lines from h...
