BackgroundStandard glucocorticoid (GC) therapy in classic congenital adrenal hyperplasia due to 21-hydroxylase deficiency (21-OHD-CAH) is often inadequate in controlling adrenal androgen excess, leading to GC over-exposure and poor health outcomes. A novel modified-release formulation of hydrocortisone (MR-HC, Chronocort® Diurnal Ltd. UK) has been shown to improve circulating adrenal androgen excess in 21-OHD-CAH. We investigated whether saliva and ...

Introduction Chronic heart failure is a catabolic state leading to cachexia in 5-15% of patients, predicting poor survival outcomes. Malnutrition affects 40% of patients with NETs and 58% with carcinoid syndrome (CS). Case 45M with severe carcinoid heart disease, on referral and admission was cachectic with BMI of 16, having lost 32 kg or 30% of body weight, meeting 50% of dietary requirements and at risk of refeeding syndrome. Nasogastric feeding (NG) w...

Background: Well-differentiated gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are commonly characterized by high-density expression of somatostatin receptors (SSTRs), which can be targeted by radiopharmaceutical therapy (RPT) via radiolabeled somatostatin analogues (SSAs). RYZ101 (225Ac-DOTATATE) is a first-in-class, highly potent alpha-emitting RPT being developed for the treatment of SSTR+ solid tumors. Alpha-particles (such as those emitted by 225<...

Background: The gonads are the major source of classic androgens during reproductive years. Additionally, the adrenal gland produces precursors for both classic and 11-oxygenated androgen biosynthesis, with androgen activation predominantly occurring in peripheral target tissues of androgen action. We used liquid chromatography-tandem mass spectrometry to profile classic and 11-oxygenated androgens in serum and saliva across the adult age range and assessed diurnal as well as ...

Introduction: Here we present our experience of managing patients with orbital well-differentiated neuroendocrine tumour (NET) metastases.Methods: Six patients were identified from the hospital NET database: four male; two female.Results: Median age at diagnosis of primary NET: 69.5 years (range: 40-74 years). Three patients were alive at time of data capture. Of those who passed away: mean survival from diagnosis of primary NET = ...

Background: Well-differentiated gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are commonly characterized by overexpression of somatostatin receptor subtype 2 (SSTR2), which can be targeted by radiopharmaceutical therapy (RPT) via radiolabeled somatostatin analogues (SSAs). RYZ101 (Ac-225 DOTATATE) is a first-in-class, highly potent alpha-emitting RPT being developed for the treatment of SSTR2+ solid tumors. Alpha-particles (such as emitted by Actinium-225) have a sho...

Background: Presence of venous vascular invasion is a criterion of intermediate risk of recurrence in papillary thyroid carcinoma (PTC). However, the presence and type of vascular invasion (lymphatic or venous) is often underreported and its impact on PTCs without other risk features remains unknown.Objective: To evaluate the impact of both lymphatic and venous invasion on the risk of recurrence/persistence on otherwise low-risk PTCs. <p class="abste...

Introduction: Gloucestershire Paediatric Diabetes Team has implemented several innovations including carbohydrate counting from diagnosis, annual review clinics and family events. We seek to improve our patient engagement and experience to improve health outcomes.Aim: Improve the clinic experience for patients, their families and staff, based on their input, thereby encouraging greater engagement and patient attendance as part of the RCPCH quality Improv...

Carcinoid syndrome occurs in 20% patients, presenting with flushing, abdominal pain, diarrhoea, and wheeze and can be challenging to manage. The standard of care for carcinoid syndrome is somatostatin analogues (SSAs) with add-on Creon, codeine and loperamide therapy. Nonetheless, half of patients experience debilitating diarrhoea. Telotristat-ethyl is a peripheral tryptophan-hydroxylase inhibitor approved for treatment of diarrhoea, supported by Phase 3 clinical trials but la...

Purpose: Neuroendocrine neoplasms are known to have heterogeneous biological behavior. G3 neuroendocrine tumours (NET G3) are characterized by well-differentiated morphology and Ki67>20%. The prognosis of this disease is understood to be intermediate between NET G2 and neuroendocrine carcinoma (NEC). Clinical management of NET G3 is challenging due to limited data to inform treatment strategies.Methods: We describe clinical characteristics, treatment, an...
