Background: We aimed to explore the relationship between continuous glucose monitoring (CGM)-derived indicators and the presence of albuminuria taking circadian features into consideration concurrently in Insulin-using patients with type 2 diabetes.Methods: We analyzed data from 129 insulin-treated type 2 diabetes patients in Korea University Ansan Hospital. Over 10 days, we collected time-series data using Dexcom G6, Fitbit, and food diaries, along with...

Background: Turner syndrome (TS) is a rare genetic developmental disorder characterized by gonadal dysfunction, short stature and heart defects, among others. Women with TS often suffer from severe fatigue, for which they are typically referred to endocrinologists. The diagnostic work-up is generally time-consuming and invasive, but it rarely solves the problem. To prevent the personal and financial burden of unnecessary diagnostic procedures, it is crucial to understand fatig...

Glucagon-like peptide-1 receptor (GLP-1R) agonists are effective treatments for type 2 diabetes and obesity. We recently described ‘biased’ peptide GLP-1R agonists modelled on exendin-4 which uncouple the pronounced endocytosis that usually accompanies GLP-1R activation, leading to prolongation of intracellular signalling responses. Here, we show that the metabolic consequences of biased GLP-1R activation in vivo are dominated by improvements in blood glucos...

Context: Sodium-glucose cotransporter 2 (SGLT2) inhibitors induce glycosuria and improve glycemic control, β cell function and insulin sensitivity in type 2 diabetes mellitus (DM2). On the other hand, these drugs predispose to diabetic ketoacidosis by increasing the tonus of glucagon. Glucagon acts on the liver and has no relevant effect on peripheral lipolysis and release of free fatty acids (FFA) as a substrate for ketogenesis, an action attributed to growth hormone (GH...

Introduction: Pancreatic islet transplantation is an effective treatment for patients with type 1 diabetes mellitus (T1DM) with unstable metabolic control. However, the quality of islets isolated from a donor is negatively affected by the inflammatory environment related to the donor’s brain death and by the stress related to islet isolation and culture. To overcome islet quality loss, some studies have co-cultured islets with mesenchymal stromal cells (MSCs). Considering...

Context: Little is known about the frequency of key mutations in thyroid cancer metastases and its relationship with the primary tumor genotype.Objectives: To evaluate the frequency of TERT promoter (TERTp), BRAF and NRAS mutations in metastatic thyroid carcinomas, analyzing primary thyroid tumors, lymph node metastases (LNM) and distant metastases.Material and Methods: Mutation analysis was performed in 437 tissue samples from 204...

Background: The detection of thyroid incidental uptake of radiopharmaceuticals has been increasing. Those detected by 18F-fluorodeoxyglucose positron emission tomography (PET) have been associated with a significant risk of malignancy (8–64%). Gallium-68 (Ga-68) labelled peptides are now the standard imaging modality for staging neuroendocrine tumours (NET). Its high sensitivity has increased the discovery of incidental findings. The aim of this study was to ev...

Thyroid cancer therapy is based on surgery followed by radioiodine treatment of tumor remnants and metastases. The incorporation of radioiodine by cancer cells is mediated by sodium iodide symporter (NIS), normally present in thyroid follicular cells’ membrane. We studied the expression of NIS in a series of 229 thyroid primary tumors using real time PCR and immunohistochemistry, and searched for possible associations between NIS expression and clinicopathological feature...

Adrenocortical carcinoma (ACC) is a rare endocrine malignancy with an unfavorable prognosis. Despite the poor prognosis in the majority of patients, no improvements in treatment strategies have been achieved. Therefore, the discovery of new prognostic biomarkers is of enormous interest. Sterol-O-acyl transferase 1 (SOAT1) is involved in cholesterol esterification and lipid droplet formation. Recently, it was demonstrated that SOAT1 inhibition leads to impaired steroidogenesis ...

Background: The Chronic Care Model (CCM), developed by Wagner et al., at MacColl Institute for Heathcare Innovation at Group Health Research Institute, Seattle, Washington, United States, is one approach to improving chronic illness care, including diabetes mellitus (DM), that is being used increasingly to assess and improve care. The CCM is based on evidence-based practices and reviews of the literature on effective care. The Patient Assessment of Chronic Illnes...
