Tolvaptan (a selective V2 receptor antagonist) is licensed for the inpatient management of SIADH induced hyponatraemia, a common complication in patients with malignancy. Licensed daily doses start at 15 mg but there is evidence that some patients have a rise in serum sodium (Na) of >12 mmol/l per 24 h in response to this. Lower initial doses (7.5 mg) may therefore be appropriate1,2.Methods: A retrospective case note audit was performed. T...

Intro/Aims: Maternal obesity is a major risk factor for the development of first onset of diabetes in pregnancy, also known as gestational diabetes mellitus (GDM). Recent studies also indicate that non-alcoholic fatty liver disease (NAFLD) is an independent predictor of GDM. Sulforaphane (SFN) is a well-known dietary activator of the redox-sensitive transcription factor Nrf2, with reported anti-adipogenic and NAFLD ameliorating effects in non-pregnant obese rodent models. In t...

The incidence of maternal obese and/or gestational diabetic (GDM) pregnancy are increasing globally, with ~10-20% of mothers classified as obese and/or GDM within the U.K. Both obese and GDM pregnancy are associated with increased risk of cardiometabolic disease, with mothers and their children at greater risk of developing later-life Type 2 diabetes, obesity and/or cardiovascular disease. Higher adiposity in pregnancy leads to increased inflammation, which may be countered by...

During pregnancy progressive maternal insulin resistance occurs which is normal, ‘sparing’ glucose that can be transported across the placenta to be used by the fetus. In gestational diabetes mellitus (GDM) maternal glucose dysregulation is exacerbated, characterised by hyperglycaemia and associated with long-term adverse outcomes in mother and child, such as increased risk of diabetes and/or cardiovascular disease in later-life. Continuous glucose monitoring (CGM) i...

Aims: To evaluate the prevalence of depression and anxiety in adult outpatients with diabetes and identify the correlation with diabetes management behaviours and clinical outcomes.Methods: Cross-sectional analyses were performed on 142 diabetic patients (type 1 diabetes n=67, type 2 diabetes n=60) attending outpatient clinic. Depression and anxiety were evaluated using the Patient Health Questionnaire (PHQ-2) and the General Anxiety Di...

Colorectal cancers (CRC) represent 9.4% of all cancers, with about 42 000 new UK cases per year. Current treatment involves surgical resection followed by radio- and chemo-therapy. 5-Fluorouracil is the standard post-operative chemotherapy although tolerance is poor due to dose-limiting toxicities and drug-resistance. New treatment strategies are therefore sorely needed. One emerging chemotherapeutic option is to target oestrogen metabolism. Our novel work rev...

Context: Nicotinamide nucleotide transhydrogenase (NNT) is a NADPH-generating mitochondrial proton pump with a central role in mitochondrial antioxidant pathways. Recent studies revealed inactivating NNT mutations in patients with familial glucocorticoid deficiency, indicating a selective susceptibility of the adrenal cortex to NNT deficiency and oxidative stress. Here we explored the potential value of NNT as a therapeutic target in adrenocortical cancer.<p class="abstext...

Introduction: Prostate cancer (PC) is dependent on androgen receptor (AR) activation by its canonical ligands testosterone and 5α-dihydrotestosterone (DHT). Intratumoural androgens persisting after castration give rise to castration-resistant PC (CRPC). These intraprostatic androgen levels are hypothesized to result from either adrenal androgen conversion or intratumoural de novo DHT synthesis through the classic or alternative pathways. Quantifying the steroid f...

Colorectal cancer (CRC) is the third most common cancer worldwide with incidence expected to rise. Although not traditionally viewed as a hormonal cancer, evidence suggests peripheral synthesis of active oestrogens worsens prognosis. Oestrogen metabolising enzymes include steroid sulphatase (STS), which desulphates oestrogens into their active forms, and 17β-hydroxysteroid dehydrogenases (17βHSD), which are estrogen oxidoreductase enzymes. We have previously shown ST...
