Background: The brain’s thermoregulatory center is stimulated by activation of neurokinin 3 receptor (NK3R) and inhibited by estrogen. In menopause, declining estrogen disturbs this balance, producing vasomotor symptoms (VMS). This study assessed response to the NK3R antagonist fezolinetant in women with menopausal VMS.Methods: This phase 2b, double-blind trial (NCT03192176) randomized menopausal women (age >40−65 y) with moderate/severe V...

Background: Colorectal cancer is the third most common cancer in the UK this had led to development of the bowel cancer screening programmes (BCSPs). It is known that ileo-colonic NETs are increasing in incidence in part thought to be related to increased endoscopy. There are few epidemiological data on rectal or ileal NETs diagnosed in BCSPs. This study aims to identify the number of NETs diagnosed through the UK BCSP.Methods: UK bowel cancer colonoscop...

Introduction: Carcinoid heart disease (CHD) develops in patients with small bowel NETs with carcinoid syndrome. Currently NT-proBNP (NTP) is suggested as the best current biomarker to screen for CHD and monitor heart failure. A number of other markers have been investigated for heart failure, however, none of these have been explored in NET patients with CHD or carcinoid syndrome. Galectin-3 (GAL3) promotes fibroblast proliferation and correlates with worse outcomes in heart f...

Background: Infrared thermography (IRT) can assess human brown adipose tissue (BAT) activity non-invasively. However, it remains unclear if skin temperature is altered in obesity. We compared skin temperatures of lean and obese individuals following cold exposure and studied its relationship with energy expenditure (EE).Methods: 10 lean (age 28.3±2.1y, BMI 21.5±0.4kg/m2) and 10 obese (age 28.2±2.1y, BMI 36.2±1.3kg/m2</...

Introduction: Pulmonary NENs account for around 2% of all pulmonary malignancy. They are classified histologically into 4 types typical and atypical carcinoids which are generally well differentiated and large cell neuroendocrine carcinoma (LCNEC) and small cell lung carcinoma (SCLC) which are poorly differentiated. Within the literature there are several reports regarding overall survival on small mainly surgical cohorts, but data for the UK population are lacking. Only a few...

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...

Introduction: Patients with neuroendocrine neoplasia (NEN) may experience psychological distress related to secretory effects of the tumour. 5-hydroxyindoleacetic acid (5-HIAA) is a metabolite of serotonin, the most important secretory product in carcinoid syndrome. This study aims to determine if urine 5-HIAA levels correlate with health-related quality of life (HRQoL) in patients with NEN.Methods: A retrospective single-centre cohort study was conducte...

Introduction: Previously published UK Cancer Registry data showed incidence of Neuroendocrine Neoplasms rising between 2001 and 2015. This was higher than had been thought (Genus et al.). We report more recent data with more accurate coding (ICD-O-3).Aim: To analyse National Cancer Registration and Analysis Service (NCRAS) data on Neuroendocrine Neoplasias (NENs) in England including years 2015–2017.Methods: Public He...

Background: Gastric and duodenal neuroendocrine tumours are increasing in incidence. ENETS guidelines suggest endoscopic resection of type 1 gastric NENs over 10 mm and consider endoscopic resection for duodenal NENs. However, the endoscopic techniques are not clearly mandated. There, is evidence to suggest endoscopic mucosal dissection has higher incidence of R0 resections compared with polypectomy or EMR alone. We have reviewed our data of endoscopic resection of gastro-duod...

Insulin-resistant diabetes is characterised by progressive pancreatic β-cell dysfunction. Elevated pancreatic islet activity of the intracellular glucocorticoid amplifying enzyme 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1) was hypothesized to drive this process in genetically obese rodents. To determine the direct effects of elevated 11β-HSD1 on β-cell function in diabetes in vivo we created a transgenic model overexpressing 11β-HSD1...
