Background: Current theragnostic techniques for pancreatic neuroendocrine tumors (pNETs) exploit the overexpression of somatostatin receptors (SSTRs) on the cell surface. However, approximately 25% of low-grade and most high-grade pNETs do not express SSTRs, requiring alternative theranostics. Calreticulin (CALR) is a protein linked to reticular calcium homeostasis and immunogenic cell death. Upon sufficient cellular insult, CALR translocates from the endoplasmic reticulum (ER...

Background: Pancreatic neuroendocrine tumors (pNETs) are slow growing, malignant tumors that show different survival outcomes by race. They are often diagnosed in late stages, with few treatments available. PNETs are the second most common pancreatic cancer and are rapidly increasing in incidence. Current size-based guidelines were largely developed in White patients and recently have been called into question for Black patients. We investigated differences of primary tumor si...

Significant knowledge gaps exist regarding the humanistic effects of hypoparathyroidism, a rare, debilitating disorder. We report results from a global survey to characterise the burden of hypoparathyroidism from the patient perspective. An anonymous survey was conducted in patients with uncontrolled chronic hypoparathyroidism (as determined by patients’ report of persistent symptoms and/or poorly controlled calcium levels as told by their physician) despite receiving con...

Background: Prior small studies have suggested increased risk of cardiovascular (CV) conditions in patients with hypoparathyroidism (HypoPT). We evaluated whether chronic HypoPT is associated with increased risk of select CV hard endpoints (i.e., myocardial infarction (MI), stroke, and a composite CV endpoint) in a large contemporary cohort.Methods: A retrospective cohort study, based on a US commercial claims database (Q1 2007 - Q2 2017), was conducted ...

Background: Insulin Lispro 200 units/ml is a concentrated rapid-acting mealtime insulin (MTI) available as a prefilled, disposable pen (IL200) indicated for adults who require >20 units/day of prandial insulin. In comparison with Insulin Lispro 100 unit/ml prefilled pen, IL200 permits the delivery of an insulin dose in half the injection volume [1] and a lower glide force [2]. This study aims to understand physicians’ reasons to prescribe IL200, as well as characteriz...

Context: ACTH-producing neuroendocrine cancer (NEC) of the thymus is rare. Lymph nodes and bone are most common metastatic sites. ACTH-secreting thymic NEC with pancreatic metastasis was only reported in one case. Most cases presented with florid Cushing syndrome (CS). Our case had thymic NEC with pancreatic metastasis, presenting with intermittent flush instead of typical CS. We demonstrate the comprehensive information of somatostatin receptors (SSTR), three different kinds ...

The thyroid gland produces thyroid hormones, which are essential regulators of growth, development and metabolism of the body and is mainly regulated by the thyroid stimulating hormone (TSH)/TSH receptor (TSHR) interplay. The TSHR couples to all four G protein families in vitro but only for the Gs and Gq signaling cascade a role has been identified in vivo. To gain further insights into the complex signaling networks mediated by G proteins in the thyroid, we generated...

Introduction: High affinity binding of pasireotide for both sst2 and sst5 leads to its enhanced efficacy in treatment of acromegaly but results in decreased secretion of insulin, incretins (GLP-1 and GIP) and, to a lesser extent, glucagon. Metformin may be a good option in patients with acromegaly experiencing hyperglycaemia with pasireotide as it improves GLP-1 secretion. We analysed data from a 12-month, Phase III, randomised study in medically naï...

We previously showed that progesterone (P4) regulates p53 expression and cell cycle progress in human umbilical venous endothelial cells (HUVEC) through progesterone receptor (PR) activation of extra-nuclear signaling pathways. Here, we showed that P4 activated the PR and hence increased the formation of progesterone receptor A-(PR-A)-NF-κB complex in both the cytosol and the nucleus. Chromatin immunoprecipitation demonstrated an interaction between PR and the NF-κB ...

Although bariatric surgery is the most effective weight loss therapy, its skeletal consequences are unclear. The aim of this study was to assess the impact of weight loss, gut hormones, adiponectin on bone loss in people undergoing Dieting (Diet), Gastric Banding (GB) and Gastric Sleeve (GS) over 24 months post-intervention.There were 15 Diet, 8 GB and 20 GS subjects with mean (±S.D.) age 53 (12) years and BMI 39 (6). At 12 months mea...
