Background: No effective blood biomarker exists to detect and clinically manage bronchopulmonary (BP) neuroendocrine tumors. We developed a blood-based 51 neuroendocrine tumor (NET)-specific transcript set to diagnose and monitor gastroenteropancreatic NETs. In this study, we examined whether the signature functioned in lung NETs. Thereafter, we examined performance metrics to assess clinical utility. The multianalyte gene signature accurately diagnosed the tumor and in additi...

Introduction: Rare genetic causes of obesity result from disruption of the melanocortin-4 receptor (MC4R) pathway, a regulator of energy balance. Patients with obesity due to variants in multiple genes, including POMC, LEPR, SRC1, and SH2B1, have shown weight and hunger reductions after treatment with setmelanotide, an MC4R agonist. DAYBREAK is a Phase 2 trial of setmelanotide in patients with additional gene variants with suggested relevance to the...

Introduction: Histology is a poor predictor of the malignant potential of phaeochromocytomas and paragangliomas (PPGL) and only the presence of distant metastasis confirms malignancy. This study reviews patterns of recurrence, treatment and mortality in patients with malignant PPGL presenting to our department at UCLH over 30 years.Materials and Methods: In our series of 128 patients with PPGL, 26 (20%) with maligna...

Background: Radioiodine treatment (RIT) for benign functioning thyroid disease is an effective treatment for patients with hyperthyroidism. The safety, preparation, administration and follow-up of treatment demands time and organisation. The planning of this elective treatment is affected by the patient’s availability which makes adequate and timely treatment of the subsequent hypothyroidism challenging. A quality improvement project was therefore set up to mitigate this....

Introduction: Primary hyperparathyroidism is a common endocrine disorder, surgery is curative. Patients with severe hypercalcemia receive cinacalcet or intravenous bisphosphonates as bridging. Intra-operative-parathyroid-hormone (IOPTH) measurement improves surgical accuracy. Bisphosphonates may increase PTH, while cinacalcet reduces it. The main aim was to assess the effect of zoledronate and cinacalcet on IOPTH.Method: Patients over 15-yo who underwent...

Glycogen storage disease 1A (GSD1A) is an inherited metabolic disorder caused by glucose-6-phosphatase (G6PC) deficiency. Patients with GSD1A present disturbed glucose homeostasis and exhibit glycogen accumulation accompanied by hepatomegaly, hypoglycemia, lactic acidosis and hyperlipidemia. However, there are currently no licensed treatments for GSD1A, and human in vitro systems for disease modelling and drug screening are lacking. We aimed to develop a human hepatoc...

Background: The beneficial effects of high protein diets on glucose homeostasis are thought to be in part mediated by the modulation of gastroenteropancreatic hormones by protein-derived metabolites such as amino acids. However, the precise mechanisms by which amino acids drive these beneficial effects are not well understood. Protein intake stimulates both insulin and glucagon release; glucagon is now recognized to have other metabolic roles besides increasing blood glucose l...

Objective: Diabetes mellitus (DM) is known to be associated with a lower trabecular bone score (TBS) and an increased risk of fracture. However, little is known regarding whether it is associated with poor bone results in pre-diabetic individuals. Despite the fact that both IFG and IGT are characterized by insulin resistance and β-cell dysfunction, the metabolic abnormalities are quite distinct between the two disorders. Impaired fasting glucose (IFG) was marked by dysfun...
