Case History: A male in his 40’s diagnosed with type 2 diabetes in 2011 (BMI:20.7 kg/m2) was admitted with DKA (Dec 2018) after a period of poor glycaemic control on oral hypoglycaemic agents (Feb 2017: HbA1c-105 mmol/mol, Nov 2018: HbA1c-115 mmol/mol). There was dramatic improvement in glycaemic control after commencing him on subcutaneous insulin (April 2019: HbA1c-56 mmol/mol). GAD65 antibodies were positive (24 u/ml; normal<5 u/ml) and a diagnosis of latent a...

Introduction: Patients with a germline loss-of-function mutation in AIP are predisposed to young-onset GH excess resulting in gigantism or acromegaly. Acromegaly leads to disease-specific cardiomyopathy with biventricular hypertrophy and diastolic dysfunction progressing to fulminant cardiac failure if left untreated, therefore it is vital to have a tractable animal model to investigate the diseaseFindings: Our AipFlox/Flox;<...

Introduction: AIP mutations are responsible for 15-30% of cases of familial isolated pituitary adenomas. The pathophysiology that drives this AIP-related pituitary tumorigenesis is not fully understood. We developed a pituitary-specific Aip knockout (KO) mouse model, which mostly recapitulates the human phenotype.Aims: To performed comparative gene expression analysis of Aip-KO mouse pituitary tumours and AIP mutation positive ...

Adiponectin has been thought to exert important influences in energy homeostasis and insulin signalling pathway. Some obese individuals showed paradoxical hyperadiponectine-mia (HA), however, the effect of HA on bone metabolism has not been fully clarified.This study aimed to evaluate bone strength and metabolic parameters according to the presence of HA and obesity in Korean adults. A total of 9,172 adults (59.4% women) aged 40–70 years assessed in...

Background: Associations between obesity and adipomyokines, inflammatory marker, and level of physical fitness have not been well evaluated in severe obesity in children and adolescents.Method: Data on leptin, irisin, FGF21, hsCRP, glucose, insulin, physical fitness measured by arm curl test for upper extremity)and wall sit test for lower extremity were obtained in 266 participants who were recruited for ICAAN study, community- based multidisciplinary we...

Background: Although sclerostin (SOST) and Dickkopf-related protein 1 (DKK1) are major regulators in bone metabolism, the associations between these soluble Wnt antagonists and osteoporotic fracture (OF) in Asians, who may have distinct biologic characteristics with Caucasians, are inconclusive. Furthermore, there have been no clinical studies separately considering non-vertebral and vertebral fractures in terms of the blood levels of SOST and DKK1.Metho...

Background: Children with HbA1cs in target within the first year of diagnosis of diabetes show tracking of future results1 and experience fewer long term complications.2 This phenomenon is called ‘metabolic memory.3 HbA1C depends on a combination of patient factors and quality of care offered by the team (intensive insulin, communication, and support). We hypothesized that well managed, supported, patients should achieve target HbA1cs at l...

Background: Bone metastases (BMs) are rare in neuroendocrine neoplasms (NENs). There is no global consensus on the optimal management, and treatment is often extrapolated from experience in other tumour groups. The aim of this study was to review the current management and outcomes of patients with BMs in NENs.Method: A retrospective study was performed of all patients with NENs, except G3 lung NENs, treated at a tertiary centre from April 2002–Marc...

Background: The KISS1 gene, is a critical regulator of normal reproductive function. In humans, KISS1 deletion results in a failure to go through puberty while activating mutations result in central precocious puberty. Administration of kisspeptin induces ovulation in rodents and sheep. However chronic exposure to exogenous kisspeptin-54 leads to profound tachyphylaxis in women with hypothalamic amenorrhoea. It is not known whether exogenous kisspeptin can alter the m...

Objectives: We investigated cardiovascular and all-cause mortality in patients who underwent gastrectomies for early gastric cancer (EGC), and analyzed the changes in metabolic parameters in these patients after surgery.Background: Bariatric surgery, including gastric banding and gastric bypass, effectively induces weight loss and resolves cardiovascular comorbidities in obese patients.Methods: 2477 patients who underwent gastrecto...
