Background: Previous studies use small for gestational age (SGA) as a surrogate marker for fetal growth restriction (FGR). SGA individuals, particularly those who show catch-up growth have greater cardiometabolic (CM) risk than those born appropriate for gestational age. However, not all FGR fetuses are born SGA. Therefore, we studied neonates born following pregnancies at increased risk of FGR, irrespective of birthweight.Aim: To define associations bet...

Background: Cardiometabolic (CM) risk is linked to being small for gestational age (SGA, birthweight <-2SDS). Suboptimal fetal growth alone may be linked with greater CM risk without resulting in SGA. Therefore, we focused on CM risk in children born following pregnancies at higher risk for growth restriction, irrespective of birthweight.Aims: 1. To identify associations between fetal and childhood weight trajectories and CM risk markers. 2. To defin...

Objectives: Kids in control of food (KICK-OFF) is a 5-day structured education programme for 11–16 year olds with type 1 diabetes who use multiple daily insulin injections. This study evaluates whether KICk-OFF would be considered a cost effective use of NHS resources by decision makers in the UK.Methods: A cost effectiveness analysis comparing KICk-OFF to usual care was conducted. Data from the KICk-OFF trial were extrapolated to simulate lifetime ...

Background: Reduced bone mineral density (BMD) z-scores from Dual energy X-Ray absorptiometry (DEXA) have been reported in childhood HSCT survivors. However, BMD z-scores are unreliable in patients with short stature.Objective: To investigate the influence of HSCT/TBI on size-corrected BMD in childhood leukaemia survivors.Method: Post-pubertal leukaemia survivors (16–26 years) treated with HSCT/TBI (10–1...

Background: Adult survivors of childhood leukaemia treated with bone marrow transplantation and total body irradiation (BMT/TBI) have an increased risk of diabetes mellitus (DM) disproportionate to their level of adiposity or other recognised risk factors. Post prandial hyperglycaemia due to reduced β-cell reserve after irradiation will be missed by fasting glucose (FG) levels. However, the UK National Institute of Clinical Excellence (NICE) screening guidelines recommend...

Background: GH deficiency (GHD) has a spectrum of severity as characterised by GH stimulation tests; the cut-off level for GHD has been a long standing contentious issue. An independent biological correlate of severity would be valuable.Objectives: To identify patterns of gene expression (GE) that correlate with severity in GHD.Methods: Pre-pubertal children with GHD (n=72) were enrolled from the PREDICT study (NCT00256126...

Background: Adult survivors of childhood acute lymphoblastic leukaemia (ALL) treated with bone marrow transplantation (BMT) and total body irradiation (TBI) have increased risk of impaired glucose tolerance (IGT) and diabetes mellitus (DM). Insulin resistance (IR) has been described, but effects of TBI on pancreatic growth and β-cell function have not been previously reported.Method: Two groups of childhood ALL survivors were studied: Group 1, treat...

Introduction: This study explores the role of different fat depots in the aetiology of abnormal glucose homeostasis in childhood ALL survivors treated with BMT and TBI using detailed body composition assessments with MRI and DEXA scanning.Method: 52 (16–26 year old) childhood ALL survivors treated with (group 1, n=21, M=11) and without (group 2, n=31, M=13) BMT and TBI and 20 obese subjects (group 3, M=10) were inv...

Introduction: Measures commonly used to assess adiposity are often considered to reflect visceral adiposity and hence used as indicators of cardiovascular risk. This study compares common clinical adiposity measures with abdominal MRI, a direct measure of visceral fat, to assess if this relationship applies in patients with abnormal body composition.Method: Fifty childhood leukaemia survivors (16–26 years) treated with bone marrow transplantation/to...

There is increased prevalence of obesity and diabetes in offspring from mothers subjected to adverse conditions during pregnancy. Our previous work demonstrated that maternal undernutrition causes epigenetic changes in hypothalamic energy regulating networks in foetal sheep. We hypothesise that these changes will persist into adulthood. Therefore, this study examined the impact of maternal undernutrition on epigenetic and mRNA expression of hypothalamic regulators of energy ba...
