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: Hybrid closed-loop (HCL) systems are characterised by integrating continuous glucose monitoring (CGM) with insulin pumps which automate insulin delivery via specific algorithms and user-initiated insulin delivery.Objectives: The aim of the study was to evaluate effectiveness of HCLs on HbA1c, time-in-range (TIR), hypoglycaemia frequency and quality of life measures in children and young people (CYP) with T1D, and their carers.<p class="...

Introduction: In many lower-middle income countries (LMICs), poverty, insufficient infrastructure and lack of universal health coverage affect type 1 diabetes (T1D) outcomes. Limited insulin and unavailability of blood glucose monitoring supplies contribute to poor glycaemic control and T1D complications that adversely affect mortality and morbidity. Laos is a LMIC in Southeast Asia (SEA) with a population of 7.3 million. Its GDP per capita is USD 2,534 of which only 2.5% repr...

Background and aims: Hypogonadotropic hypogonadism is characterised by inadequate secretion of gonadotropins (luteinising hormone (LH) and follicle-stimulating hormone (FSH)) leading to absent, partial or arrested puberty. In males, classical treatment with testosterone promotes virilisation but does not facilitate testicular growth or spermatogenesis. Conversely, treatment with gonadotropins or gonadotropin-releasing hormone (GnRH) stimulates Sertoli and Leydig cells directly...

Background: Neonatal hyperthyrotropinaemia (HT) is defined by elevated thyroid stimulating hormone (TSH) and normal free-thyroxine (FT4) level. Persistent HT in the neonatal period is often a diagnostic dilemma for clinicians to either treat to prevent subclinical hypothyroidism or to wait and monitor thyroid function tests (TFTs).Methods: As part of an audit, 1449 term infants who had TFTs undertaken as part of a prolonged jaundice screen from 2012&#150...

Introduction: The prevalence of diabetes continues to rise worldwide placing an increasing burden on the national health service. In 2012 a national Best Practice Tariff (BPT) was introduced in the UK and a National Peer Review Quality Assurance Programme was developed to drive improvements in diabetes care for children and young people. Our national audit from 2010 to 2018 aims to explore trends in paediatric diabetic care within the North West Diabetes Network and assess the...

Recent acute in vivo studies have shown that structural modifications of dogfish glucagon improves peptide stability and these analogues can act as dual agonists at both glucagon and GLP-1 receptors. Here, we compared the effects of chronic (51 days) twice daily administration of [D-Ala2]dogfish glucagon (Pep-N) and [D-Ala2]dogfish glucagon-exendin-4(31–39) construct (Pep-C), exendin-4(1–39) or saline treat...

Introduction: Abdominal obesity and insulin resistance are risk factors for erectile dysfunction (ED). ED is associated with hypoandrogenism, endothelial dysfunction, lower urinary tract symptoms (LUTS), and reduced quality of life (QoL). We aimed to compare effects of lifestyle modification-induced weight loss on insulin resistance, endothelial and sexual function, LUTS and QoL in obese non-diabetic men with and without ED.Methods: Seventy abdominally o...

Introduction: Androgen deficiency (AD) is associated with endothelial and erectile dysfunction, lower urinary tract symptoms (LUTS) and reduced quality of life (QoL) in obesity. We aimed to compare effects of weight loss induced by lifestyle modification on endothelial and erectile function, LUTS and QoL in obese men with and without AD.Methods: abdominally obese Asian (body mass index≥30 kg/m2, waist circumference [WC] ≧ 90 cm) m...

Introduction: Expression of murine CSP-1/Dcpp secretory proteins was first identified in sublingual salivary glands and subsequently in secretory epithelia of several other tissues, including the mouse female reproductive tract where expression is regulated by oestrogen. Preliminary studies indicated that HRPE773, the human CSP-1/Dcpp orthologue, displayed a similar pattern of expression to its murine counterparts. We therefore hypothesized that HRPE773 might be expressed in h...
