Role of Thyrotropin-Releasing Hormone Stimulation Test and Autoantibody in 952 Subjects with Subclinical Hypothyroidism.

Context: Subclinical hypothyroidism (SCH) is characterized by elevated thyroid-stimulating hormone (TSH) levels and normal free thyroxine (fT4) levels. In upper normal TSH levels, thyrotropin-releasing hormone (TRH) stimulation test proved to be useful in identifying an exaggerated TSH response.

Objective: We aimed to evaluate the incidence and predictive ability of basal TSH, anti-thyroid peroxidase antibodies (TPOAb), and anti-thyroglobulin antibodies (TgAb) for exaggerated TRH stimulation test in SCH.

Computed tomography evaluation of skeletal muscle quality and quantity in people with morbid obesity with and without metabolic abnormality.

We investigated the differences in quantity and quality of skeletal muscle between metabolically healthy obese (MHO) and metabolically unhealthy obese (MUO) individuals using abdominal CT. One hundred and seventy-two people with morbid obesity who underwent bariatric surgery and 64 healthy control individuals participated in this retrospective study. We divided the people with morbid obesity into an MHO and MUO group.

Endocrine disorders associated with obesity.

Several endocrine disorders, including diabetes, insulinoma, Cushing syndrome, hypothyroidism, polycystic ovarian syndrome, and growth hormone deficiency, are associated with obesity. The mechanisms underlying the development of obesity vary according to the abnormalities of endocrine function. The primary actions of insulin, glucocorticoids (GCs), thyroid hormone, and growth hormone are associated with energy metabolism in the liver, muscle, adipose tissue, and other tissues.

Subclinical thyroid dysfunction and chronic kidney disease: a nationwide population-based study.

Background: Chronic kidney disease (CKD) has a significant impact on global health.

We aimed to evaluate the risk of CKD according to thyroid function status in a large cohort.

Risk of carotid plaques according to triglyceride-glucose index stratified by thyroid function: A cross-sectional study.

Background: Recent studies have indicated that the triglyceride-glucose (TyG) index or subclinical thyroid dysfunction is associated with carotid plaques, a predictor of cardiovascular disease risk. However, evidence for this association is limited and inconsistent. This study aimed to evaluate the risk of carotid plaques according to TyG index and thyroid function status in the general population.

Association between iodine intake and metabolic syndrome in euthyroid adult in an iodine-replete area: a nationwide population-based study.

However, the association between thyroid autoimmunity and MetS is uncertain. This study aimed to investigate the relationship between thyroid autoimmunity and MetS in a large cohort study of euthyroid subjects.

Effect of bariatric surgery on circulating and urinary mitochondrial DNA copy numbers in obesity with or without diabetes.

Introduction: Recent studies have suggested that extracellular circulating and urinary mitochondrial DNA (mtDNA) are associated with mitochondrial dysfunction in obesity and type 2 diabetes mellitus (T2DM). However, the changes to cell-free serum and urinary mtDNA after bariatric surgery in patients with obesity with T2DM have not been investigated to date.

Research Design And Methods: We prospectively recruited patients with obesity (n=18), and with obesity and T2DM (n=14) who underwent bariatric surgery, along with healthy volunteers (HV) as a control group (n=22).

Effect of diabetes on exosomal miRNA profile in patients with obesity.

Introduction: Obesity is a risk factor for type 2 diabetes mellitus (T2DM) and cardiovascular disease. T2DM increases the risk of cardiovascular-related death. We investigated changes in circulating exosomal microRNA (miRNA) profiles in patients with DM with obesity compared with patients without DM with obesity.

Shear wave elasticity by tracing total nodule showed high reproducibility and concordance with fibrosis in thyroid cancer.

Background: Although shear wave elastography (SWE) is reported to be useful in detecting malignant thyroid nodules, it shows a wide range of cut-off values of elasticity index (EI) in detecting malignant nodules. The cause of discrepancy remains unclear. Fibrosis of the tumors is known to increase the EI in SWE, and matching of SWE and surgical histopathology has not been fully illustrated in thyroid cancer.

A novel non-PPARgamma insulin sensitizer: MLR-1023 clinicalproof-of-concept in type 2 diabetes mellitus.

Aim: MLR-1023, called Tolimidone when evaluated unsuccessfully by Pfizer for gastric ulcer disease, has been repurposed as a novel oral insulin sensitizer with its effects mediated by selective activation of Lyn kinase.

Is There a Difference in Serum Vitamin D Levels and Bone Mineral Density According to Body Mass Index in Young Adult Women?

Background: In the life cycle, bone mineral density (BMD) is the most optimal condition in the 20s. In Korea, vitamin D deficiency status is very serious in Korean women due to recent lack of activity, weight polarization, and inadequate nutritional intake. The purpose of this study was to compare serum vitamin D and BMD according to obesity status in Korean young adult women.

The circulating exosomal microRNAs related to albuminuria in patients with diabetic nephropathy.

Background: Diabetic nephropathy (DN) is associated with high risk of cardiovascular disease and mortality. Exosomal microRNAs (miRNAs) regulate gene expression in a variety of tissues and play important roles in the pathology of various diseases. We hypothesized that the exosomal miRNA profile would differ between DN patients and patients without nephropathy.

Efficacy and Safety of Omega-3 Fatty Acids in Patients Treated with Statins for Residual Hypertriglyceridemia: A Randomized, Double-Blind, Placebo-Controlled Clinical Trial.

Background: Cardiovascular risk remains increased despite optimal low density lipoprotein cholesterol (LDL-C) level induced by intensive statin therapy. Therefore, recent guidelines recommend non-high density lipoprotein cholesterol (non-HDL-C) as a secondary target for preventing cardiovascular events. The aim of this study was to assess the efficacy and tolerability of omega-3 fatty acids (OM3-FAs) in combination with atorvastatin compared to atorvastatin alone in patients with mixed dyslipidemia.
