Glomus jugulare tumours are rare and often difficult to manage. A small proportion of these tumours (1–3%) can cause symptoms due to catecholamine secretion. Here we describe a patient with secretory glomus jugulare tumour treated with steriotactic radio surgery and its effect on catecholamine secretion.Case report: A 39-year-old lady was referred to ear specialists with the characteristic symptoms of pulsatile tinnitus and decreased hearing in the ...

Adipose tissue produces several hormones and cytokines termed ‘adipokines’ that have widespread effects on carbohydrate and lipid metabolism. They appear to play an important role in the pathogenesis of insulin resistance, diabetes, and atherosclerosis. Chemerin is a novel adipokine, highly expressed in obese, insulin-resistant subjects. Polycystic ovary syndrome (PCOS) is associated with insulin resistance and obesity. We assessed chemerin levels in sera and adipose...

Orexin-A and orexin-B orchestrate their diverse central and peripheral effects via two G-protein coupled receptors, OX1R and OX2R, which activate multiple G-proteins. They are involved in a host of physiological processes including, steroidogenesis, appetite control and energy regulation. Whilst some signalling mechanisms have been proposed for individual recombinant orexin receptors in generic mammalian cell types, it is clear that the peripheral effects of orexin are spatial...

Background: Growing evidence suggests that hypothalamic lipid sensing plays a key role in controlling food intake, fat deposition and energy balance and that its dysregulation could lead to obesity and type 2 diabetes (T2D). Recent investigations reported that sphingosine-1-phosphate (S1P) is involved in the hypothalamic control of energy homeostasis. Intra-cerebroventricular administration of S1P decreased food intake and increased energy expenditure in rodents.<p class="...

Vitamin D (vit-D) deficiency is common in patients with gastro-entero-pancreatic neuroendocrine tumours (GEP-NET) and has been linked to reduced survival in these patients. Vit-D status was assessed in 183 patients with GEP-NET, at the time of their first presentation in the ARDEN-NET-Centre; and following simple advice at routine 6-monthly follow-up appointments to increase vit-D intake using over-the-counter vit-D preparations (Colecalciferol (Vit-D3), 1000–2000 units/d...

Introduction: Nonalcoholic fatty liver disease (NAFLD) is the leading cause of chronic liver disorders. Endocan is a novel molecule of endothelial dysfuction which is expressed in liver. SGLT2i have been reported to improve NAFLD through amelioration of inflammation. While there are contradictory results regarding the serum endocan levels in NAFLD patients, data regarding endocan expression in liver tissue are limited. Aim: Herein, we aimed to investigat...

Chemerin, a chemoattractant protein, acts via a G-protein coupled chemokine receptor, i.e. Chemokine like Receptor 1/ChemR23; levels of which are elevated in pro-inflammatory states such as obesity and type 2 diabetes mellitus (T2DM). Obesity and T2DM patients are at high risk of developing cardiovascular disorders such as atherosclerosis. We have reported that chemerin induces human endothelial cell angiogenesis and since dy...

Paltusotine is an investigational oral, once-daily, non-peptide, SST2 agonist in development for the treatment of acromegaly and neuroendocrine tumors. Interim analysis results from subjects with acromegaly treated with paltusotine for up to 2 years in ACROBAT Advance (NCT04261712), an ongoing, open-label extension study are reported here. Prior to Advance, subjects previously completed one of two Phase 2 parent studies, Evolve (NCT03792555, with normal IGF-1 using injected lo...

Background: The Royal College of Physicians (RCP) called earlier this year for obesity to urgently be recognized as a disease, and warned that until this happens its prevalence is unlikely to be reduced. Obesity is associated with multiple comorbidities, including type 2 diabetes mellitus (T2DM), hypertension (HT), and dyslipidemia. Bariatric surgery (BS) produces dramatic weight loss, with improvement of obesity associated comorbidities and decrease of overall mortality.<...
