Hemoglobin A1c (HbA1c) is used for the long-term management of patients with diabetes mellitus (DM). Hemoglobin variants other than HbA1c and e-N-lysine-glycated HbA0 may cause analytical interference in determinations of HbA1c. Hemoglobin J is an abnormal hemoglobin, an alpha globin gene variant and present in various geographic locations. Hemoglobin J (depending on its type) has different characteristics and functions. For example hemoglobin J Capetown (α2 92Gln β2...

Introduction: Gas chromatography mass spectrometry (GC-MS) is the gold standard method for urinary steroid profiling. However, GC-MS requires chemical derivatisation, long run times, is labour intensive, expensive, and unsuitable for rapid multi-sample analysis, limiting its use in routine clinical practice. GC-MS urinary steroid metabolomics, the combination of steroid profiling and machine learning (Generalized Matrix Learning Vector Quantization) was shown to have superior ...

Objective: To investigate the results of J – 131 treatments in patients (pts) with autonomous thyroid adenomas in long period of follow up.Material and Methods: We enrolled 68 consecutive pts with Plummer’s disease (50 females, 18 males, mean age 54,7 yrs, range 21 – 79 yrs) for period 2000 – 2020 yrs. 87%(59/68) pts had a unifocal nodule, while 13% (9/68) pts had multifocal toxic autonomous nodules. Pts stopped antithyroid drugs for ...

Introduction: Polycystic ovary syndrome affects 10% of women and comes with a 2-3fold increased risk of type 2 diabetes, hypertension, and fatty liver disease. Androgen excess, a cardinal feature of PCOS, has been implicated as a major contributor to metabolic risk. Adrenal-derived 11-oxygenated androgens represent an important component of PCOS-related androgen excess and are preferentially activated in adipose tissue. We aimed to identify PCOS sub-types with distinct androge...

Introduction: Polycystic ovary syndrome (PCOS) affects 10% of women and is associated with a 2-3fold risk of type 2 diabetes (T2D), hypertension, fatty liver and cardiovascular disease. Androgen excess has been implicated as a major contributor to metabolic risk in PCOS. We aimed to identify PCOS sub-types with distinct androgen profiles and compare their cardiometabolic risk.Methods: We cross-sectionally studied 488 tre...

Background: Hypertension affects more than 30% of the adult population worldwide and is a major cardiovascular risk factor. Identifying secondary causes of hypertension is key to offering targeted treatments and mitigating adverse health outcomes. We tested the performance of urine steroid metabolomics (USM), the computational analysis of 24-hour urine steroid metabolome data by machine learning, for diagnosing endocrine forms of hypertension.Methods: 14...

J J Kopchick, Ohio University, Athens, Ohio, USA. AbstractDr John J Kopchick is an internationally recognized leader in the growth hormone (GH) field. Since 1987, he has held the Milton and Lawrence H Goll Eminent Scholar Professorship in Molecular and Cellular Biology and directs the Growth/Obesity/Diabetes Section of the Edison Biotechnology Institute at Ohio University in Athens, Ohio. He also is Professor in the B...

Introduction: Brown adipose tissue (BAT) increases energy expenditure and is a potential therapeutic target for obesity and associated cardiometabolic disease. It is unclear whether human BAT activity is reduced in obesity, as BAT 18F-fluorodeoxyglucose uptake is reduced but BAT metabolic activity measured using11C-acetate PET is preserved. BAT thermogenesis relies on the presence of uncoupling protein 1 (UCP1), which uncouples oxidative phosphorylation f...

The obesity epidemic has underlined the need for new treatments to aid weight loss and prevent the associated sequelae of obesity such as type 2 diabetes, hypertension, dyslipidaemia and cardiovascular disease. The relatively recent discovery of brown adipose tissue (BAT) in adult humans has revived interest in activating this tissue to increase energy expenditure as a novel treatment for obesity and associated metabolic disease. BAT is a thermogenic organ that generates heat ...

The obesity epidemic has underlined the need for new treatments to aid weight loss and prevent the associated cardiometabolic sequelae of obesity. The relatively recent discovery of brown adipose tissue (BAT) in adult humans has revived interest in activating this tissue to increase energy expenditure as a novel treatment for these conditions. BAT is a thermogenic organ that generates heat to maintain body temperature in a cold environment. While BAT mass and activity are redu...
