Introduction: Non-Alcoholic Fatty Liver Disease (NAFLD) is reported to be common in patients undergoing bariatric surgery, but the diagnostic accuracy of non-invasive NAFLD biomarkers to stage disease and track progress longitudinally has not been assessed.Methods: 274 patients undergoing bariatric surgery were included in the study. Intra-operative liver biopsies were taken from 163 patients and histologically graded using t...

Radioiodine treatment is the cornerstone of differentiated thyroid cancer (DTC) management. A number of thyroid cancers, however, become radioiodine-refractory (RAIR) and these represent about 60% of advanced DTCs and are responsible for the vast majority of DTC mortality. RAIR DTC has limited therapeutic options, mainly tyrosine kinase inhibitors that are associated with moderate efficacy and considerable toxicity. Reinducing NIS expression (redifferentiation) with the aim of...

Background: Sodium glucose co-transporter 2 inhibitors reduce the incidence of cardiovascular events in patients with type 2 diabetes mellitus based on the results of recent cardiovascular outcome studies. Herein, we investigated the effects of long-term treatment with empagliflozin on biochemical and immunohistochemical markers related to atherosclerosis development in apolipoprotein E knockout [Apo-E(−/−)] mice.Methods: At the ag...

Sodium glucose co-transporter2 (SGLT2) inhibitors reduce the incidence of cardiovascular events in patients with Type 2 Diabetes Mellitus (T2DM) based on the results of recent cardiovascular outcome studies. Herein, we investigated the effects of long-term treatment with canagliflozin on biochemical and immunohistochemical markers related to atherosclerosis and atherosclerosis development in the aorta of Apolipoprotein E knockout (Apo-E(−/−)) mice. After...

Aims/hypothesis: Genetic and functional defects in mitochondria are linked with phenotypes of obesity, hypercholesterolemia, and type 2 diabetes (T2DM). However, the impact on mitochondria during surgery-induced metabolic recovery is unknown. We therefore studied the effect of restrictive versus malabsorptive bariatric procedures on indicators of mitochondrial efficiency and control of biogenesis/function.Methods: Forty-three morbidly obese, T2DM consent...

Oxidative stress in humans has been associated with obesity. Puberty is a maturation period characterized mainly by changes of the GH and the gonadotrophin hormones secretion. To investigate the possible association of the GH and the hypothalamic–pituitary–gonadal (HPG) axes before and during early puberty, with the pro- and anti-oxidation mechanisms 76 healthy, pre-pubertal normal weight (n=28), pre-pubertal obese (n=11), early pubertal normal weig...

Background: Although IV steroids are the treatment of choice for moderate-to-severe graves orbitopathy (M-S GO), the most efficacious regimen is not yet defined. Cases not responding or relapsing after steroid treatment (STx) are not uncommon and STx can cause serious adverse events. The aim of the present study is to define the steroid regimen which balances between efficacy and damage, using stir-sequence orbital-MRI (SsMRIo) as an additional objective tool for the evaluatio...

Background and aims: Bariatric surgery can lead to a quick reversal in type 2 diabetes mellitus (T2DM) status. However, despite this reversal inflammatory responses may still persist via activation of Toll-like receptors (TLR) within adipose tissue (AT); with triglycerides (TGs) noted as a potential mediator of such inflammation. Therefore the aims of these studies were to understand the impact of TG changes, pre- and post-bariatric surgery, on TLR expression in ex vivo</e...

Background: In obesity, excess nutrients and an increased demand for protein synthesis contribute to unfolded proteins accumulating within the endoplasmic reticulum and consequent activation of unfolded protein response (UPR). UPR in adipose tissue (AT) is critical to the initiation and integration of inflammation and insulin signalling pathways in obese and type 2 diabetes mellitus (T2DM) patients. The aim of this study was to examine whether novel malabsorptive or bypass bar...
