Background: Adipogenesis is a key process leading to adipose tissue (AT) expansion. However, managing this event is critical to limit excessive fat accumulation and disease risk. Adipogenesis appears controlled in part, through Wnt10b signalling which reduces adipogenesis via inhibiting CCAAT/enhancer-binding protein alpha (CEBPα) although the molecular mechanism remains unclear.Aims: Abdominal subcutaneous AT (AbdSc AT) was collected from a, non-di...

Background: In obesity, excess nutrients and an increased demand for protein synthesis contribute to unfolded proteins accumulating within the endoplasmic reticulum and consequent activation of unfolded protein response (UPR). UPR in adipose tissue (AT) is critical to the initiation and integration of inflammation and insulin signalling pathways in obese and type 2 diabetes mellitus (T2DM) patients. The aim of this study was to examine whether novel malabsorptive or bypass bar...

Background: Endoplasmic reticulum (ER) stress in adipose tissue (AT) is critical to the initiation and integration of inflammation and insulin signalling pathways in obese and type 2 diabetes mellitus (T2DM) patients. It induces an unfolded protein response (UPR) to restore functional integrity which leads to upregulation of three master regulators of ER; PKR-like ER-regulated kinase (PERK), inositol requiring enzyme1α (IRE1α) and activating transcription factor6 (AT...

Introduction: There are patients who remain symptomatic with hypothyroidism despite apparent adequate replacement on levothyroxine (LT4) therapy. We present an observation where monozygotic twins responded only to combination therapy with liothyroinine (LT3), and were found to have a genetic variation which may have clinical significance in thyroid metabolism.Case report: A 47-year-old female with polyglandular auto-immune syndrome (APS1) presented with ...

Introduction: Hypo-&hyperkalaemia are common laboratory abnormalities, complicating up to 10% of all hospital admissions and contributing to mortality. Ideally, patients with mild deviations can be treated as outpatients, and only those patients with objectively severe or life-threatening levels are hospitalized. Once admitted, there are few data as to whether the degree of electrolyte disturbance consumes greater resource(s). We analysed the admission and discharge data, ...

Objective: Arthropathy is the commonest morbidity in acromegaly and the main determinant of quality of life in these patients. Most of current knowledge is derived from studies using conventional x-rays. This study aims to characterise acromegalic arthropathy using modern imaging techniques.Methods: Case control study comprising of 60 acromegaly patients (29 males, mean age 54.8± 12.9yrs) and 300 age/gender-matched controls from the publicly availab...

Introduction: Polycystic Ovary syndrome (PCOS) is a metabolic disorder associated with increased cardiovascular disease risk. Exercise is an effective treatment strategy to manage symptoms and reduce long-term health risk. High-intensity interval training (HIIT) has been suggested as a more efficient exercise mode in PCOS; however, it is not clear whether HIIT is superior to moderate intensity steady state exercise (MISS).Methods: We synthesized availabl...

Background: Hyponatraemia (most commonly secondary to SIADH) is very common in cancer patients; it is associated with delays to oncology treatment and mortality.Aim: To evaluate the number of patients with hyponatraemia at a tertiary referral cancer centre and assess adherence to national recommendations for investigations and treatment.Methods: All biochemistry results (in-patient and outpatient) analys...

Aims: Endocrine Society (ES) acromegaly guidelines (2014) addressed complication screening. Uncontrolled acromegaly is associated with elevated cardiovascular mortality due to risk factors including hypertension (HT), diabetes mellitus (DM), obstructive sleep apnoea (OSA), and with an increased risk of colorectal cancer and polyps among other types of neoplasias. We audited our clinical practice with regards to acromegaly complication screening.Methods: ...

Aim: Endocrine Society (2016) published guidelines for hormonal replacement in hypopituitarism. Central hypothyroidism (CH) is defined as fT4 below reference range and mild CH is defined as fT4 in the low-normal range with suggestive symptoms in the context of pituitary disease. In patients with panhypopituitarism levothyroxine in doses sufficient to achieve fT4 levels in the upper half of the reference range is recommended. In our centre...
