A 58 year old female, with a 15 year history of hypertension and recent poor control, was admitted to the emergency department after an out of hospital cardiac arrest due to ventricular fibrillation requiring DC cardioversion. Initial investigations showed a metabolic alkalosis with profound hypokalaemia at 1.7 mmol/l. In view of lateral ST depression on the ECG post-resuscitation, she underwent an urgent coronary angiogram which demonstrated unobstructed coronary arteries. Wh...

Background: GLP-1/glucagon dual agonists are being developed as treatments for obesity due to their combined effect of reducing food intake while increase energy expenditure. Though the effect of the dual agonist on carbohydrate and lipid metabolism is well studied, little is known about the effects on protein metabolism. This study aimed to examine the acute and chronic effects of the GLP-1/glucagon dual agonist on amino acid metabolism.Methods: The lon...

Case history: We present the case of a 72-year-old female who was referred to the endocrinology service following the identification of a pathogenic germline mutation in the SDHA gene (c.91C>T, p.Arg32*) as part of a genetic panel for hypertrophic cardiomyopathy. There was no personal or family history of phaeochromocytoma or paraganglioma (PPGL), gastrointestinal stromal tumours or pituitary adenoma.Investigations: Our patient was reviewed ...

Background: Literature suggests that whole glucose excursion, rather than plasma glucose concentration at a point, provides more information about glucose tolerance. The glucose area under the curve (AUC) is an index of whole glucose excursion after glucose load. We sought to investigate changes in insulin and glucose homeostasis, including the glucose AUC, 5 years after bariatric surgery.Method: A non-randomised prospective study of 18 participants with...

Background: Bariatric surgery aims to decrease cardiovascular risk factors. The Swedish Obese Subjects study reported that bariatric surgery was associated with reduction in long-term cardiovascular (CV) event. However, uncertainty remains regarding the effect of bariatric surgery on long-term CV risk. One way to predict long-term CV risk after bariatric surgery is to use cardiovascular risk assessment models.Aim: The aim of this study is to investigate ...

Phosphorylation of the Androgen Receptor (AR), has been shown to play an important role in directly modulating AR activity. However, the full extent of which protein kinases are involved in the regulation of the AR remains unknown. In order to address which kinases are important in the regulation of AR activity in both androgen sensitive and independent prostate cancer (PCa), a comprehensive siRNA kinome screen was performed. AR transcriptional regulation was evaluated using a...

Aim: To determine the association between recorded inpatient glycaemic variability and long-term mortality in patients with diabetes mellitus.Methods: Inpatient capillary blood glucose (CBG) readings from eight acute hospitals were included. Data was analysed from first admission within the dataset with >4 measured CBGs. 28 353 admissions were identified (24 181 type 2 DM, 4,172 type 1 DM). Matching parameters were: age, diabetes duration, admission ...

Introduction: The investigation and management of large adrenal lesions varies widely. It is appropriate to have a low threshold for surgical removal of large adrenal lesions with the possible exception of stable adrenomyelipomata. 18F-FDG PET is increasingly used as an imaging technique to assess these lesions. We would like to highlight the potential benefits and pitfalls of using 18F-FDG PET as part of the diagnostic pathway.Method: Since 2008, 18F-FD...

Introduction: The circadian clock controls numerous aspects of mammalian physiology across the 24 hour day, including lipid and glucose metabolism. Disruption of the core circadian gene CLOCK is associated with the development of obesity, diabetes and the metabolic syndrome in mice. Women with Polycystic Ovary Syndrome (PCOS) are at increased risk of developing diabetes, dyslipidemia and the metabolic syndrome. The aim of the present study was to investigate the relationship o...

We describe the case of two patients who presented with non-mechanical bowel obstruction as a consequence of an underlying, undiagnosed Phaeochromocytoma. The first patient was referred in to the surgical team by his GP with signs and symptoms of small bowel obstruction. He described abdominal pain, distension and vomiting and had not opened his bowels for a week. The X-ray supported the clinical diagnosis and he went on to have an abdominal CT scan. The scan did not identify ...
