Context: Surgery is the first-line treatment option for thyrotropinomas, but medical therapy with somatostatin receptor ligands (SRL) may be used as neoadjuvant treatment and to facilitate safe surgery.Objectives: To determine the extent to which neoadjuvant SRL (i) corrects clinical, laboratory and tissue hyperthyroidism in thyrotropinomas, (ii) induces tumour shrinkage in macroadenomas, and (iii) aids microadenoma detection by 11C-methionine...

The pituitary gland is a critical endocrine organ regulating multiple essential physiological processes including growth, reproduction, metabolism and the stress response. Hormone-producing pituitary cell lineages are derived from a population of embryonic precursors expressing the transcription factor SOX2. These cells maintain multipotency into early postnatal life, acting as the resident population of pituitary stem cells (PSCs) and contributing to all the endocrine cell li...

Paltusotine is an investigational oral, once-daily, non-peptide, SST2 agonist in development for the treatment of acromegaly and neuroendocrine tumors. Interim analysis results from subjects with acromegaly treated with paltusotine for up to 2 years in ACROBAT Advance (NCT04261712), an ongoing, open-label extension study are reported here. Prior to Advance, subjects previously completed one of two Phase 2 parent studies, Evolve (NCT03792555, with normal IGF-1 using injected lo...

Pregnancies affected by GDM commonly result in large-for-gestational-age (LGA) infants, which have an increased risk of developing cardiometabolic complications. The mechanisms responsible are unclear but are associated with altered placental physiology. We have previously reported that miRNAs, including pancreatic specific miR-375, are altered in maternal serum extracellular vesicles (EVs) prior to the onset of LGA, and in term placenta. We assessed maternal pancreatic-derive...

Background: Existing biomarkers have limited ability to discriminate indolent non-functioning pituitary adenomas (NFPAs) from those with a propensity to recur following primary surgery. Radiomics, the extraction of quantitative data from medical imaging, is increasingly recognised as a tool to augment clinical decision making.Methods: 39 patients who underwent primary trans-sphenoidal surgery for an NFPA between January 2007 and April 2017, were enrolled...

Hypoactive sexual desire disorder (HSDD) is a persistent lack of sexual desire, causing marked interpersonal distress. It is the most common global female sexual health problem, although the precise pathophysiology remains uncertain. Existing treatment options are limited by their efficacy and side effects. The neuropeptide kisspeptin offers a potential therapeutic target given its emerging role in modulating reproductive behaviour. Using a combination of psychometric, neuroim...
