There is considerable evidence to indicate that the hypothalamic-pituitary-adrenal axis is activated in obesity and that glucocorticoids may have a stimulatory effect on adipocyte leptin production. However, the precise interactions between glucocorticoids and leptin are complex and remain poorly understood. To investigate whether the glucocorticoid/leptin interaction is affected by genetic factors, we investigated the heritability of BMI, leptin and glucocorticoid metabolite ...

Congenital hypogonadotropic hypogonadism (CHH (MIM161110)) due to GnRH deficiency is a rare genetic disorder (affects ~1/30 000) characterised by abnormal pubertal development and infertility. Over 60% cases have anosmia (Kallmann syndrome) and some exhibit additional phenotypes. CHH is a genetically heterogeneous developmental disease. Most cases present sporadically, although familial forms (AD, AR, and X-linked) with incomplete penetrance and variable expressivity occur. Re...

Background: Various social determinant of health (SDOH) metrics and indices are utilized to evaluate access to cancer care and to explain disparities in outcome in pancreatic neuroendocrine tumors (PNETs). Little prior work has compared the validity of various geographic metrics. Therefore we aimed to examine different geographic metrics validity (from smallest to largest: census block group< census tract< zip code< county) utilizing single institutional data in a ...

Background: Tumor size and lymph node involvement (stage) have been utilized to prognosticate pancreatic neuroendocrine tumors (PNETs) but the influence of race and social vulnerability on these factors remains unexplored. Therefore we sought to explore this in a racially and socioeconomically diverse cohort.Methods: We reviewed records of all patients who underwent surgical resection for PNETs from 2006-2022 at a single NCI-designated cancer center in t...

The FGF signalling pathway regulates cell proliferation, differentiation, migration and cell specification in mutliple developing and adult tissues. It has also been implicated in tumor development and progression with a significant role in the cancer pathobiology of several malignant tumors including melanoma, breast, pancreas, head and neck and non-small lung cell cancer. FGF signalling plays a major role in the postnatal hypothalamic-pituitary (HP) axis, with dysregulation ...

UK National Acromegaly Register collects data on real-life clinical practice in 34 centres. We analysed all GH and IGF1 data to assess adequacy of control on medical treatment (Rx) with somatostatin analogs (SMS) and dopamine agonists (DA).Methods: All GH records (basal, profile or GTT) in database were correlated with IGF1, Rx, surgery (TSS) and radiotherapy (RT), then processed to derive summary data for each patient and each course of Rx. GH considere...

UK National Acromegaly Register collects data on routine clinical practice in 34 centres. We analysed all GH and IGF1 data to assess adequacy of control & responses to medical treatment (Rx) with somatostatin analogs (SMS) & dopamine agonists (DA). Methods: Under program control, GH records (basal, profile or GTT) were correlated with IGF1, tumour size, Rx, surgery (TSS) & radiotherapy (RT) in the database, then processed in Excel to derive summary data for each pa...

Objectives: To assess bone mineral density (BMD) and body composition in adults with congenital adrenal hyperplasia (CAH).Setting: Endocrine clinics in seventeen centres throughout the UK participating in CaHASE, a Society for Endocrinology project.Study design and subjects: Cross-sectional survey of 203 adults with CAH (65 men, 138 women: median age 33 (range 18–70) years). Hundred and sixty six patients were classified as cl...

The anterior pituitary gland is a critical endocrine organ responsible for many important physiological processes including puberty, fertility, metabolism and the stress response. It is derived from, and maintained by, a population of SOX2+ progenitor/stem cells which become more quiescent with age until their direct contribution to tissue turnover becomes negligible. Previous research has demonstrated that the postnatal SOX2+ population exhibits heterogeneity in terms of mark...
