Objectives: Thyroglobulin (Tg) is an established tumor marker for differentiated thyroid carcinoma (DTC) patients. However, Tg immunoassays can be subject to autoantibody (TgAb) interference resulting in incorrect Tg values. Tg measurement with liquid chromatography-tandem mass spectrometry (LC-MS/MS) could be promising in patients with TgAbs. In this study, we compared a Tg immunoradiometric assay (Tg-IRMA) and a Tg-LC-MS/MS analytically in the presence of TgAbs. Furthermore,...

Introduction: The endocrinologist is confronted with an increasingly large population of postbariatric patients who present with endocrine problems. One of these is early dumping, a complication that may be the result of increased entero-endocrine activity. To address the prevalence of early dumping and to gain further insight into its pathophysiology, we performed a Mixed Meal Tolerance Test (MMTT) in a random sample of patients after Roux-en-Y gastric bypass (RYGB).<p cl...

Background: Pediatric differentiated thyroid cancer (DTC) has an excellent prognosis, but has unknown late effects of treatment. Initial cardiac evaluation showed subclinical diastolic dysfunction in 20% of adult survivors. In this follow-up study, we determined the clinical course of this finding.Methods: This multicenter study, conducted between 2018 and 2020, re-evaluated survivors 5 years after the first evaluation. The primary endpoint was echocardi...
