Context and objective: Active Cushing’s disease is associated with cognitive impairments. We hypothesized that previous hypercortisolism in patients with Cushing’s disease results in irreversible impairments in cognitive functioning. Therefore, our aim was to assess cognitive functioning after long-term cure of Cushing’s disease.Design: Cognitive assessment consisted of 11 tests, which evaluated global cognitive functioning, memory, and ex...

Background: Patients with neuroendocrine tumors (NETs) have a 5-year survival rate of 30-60%. Surgery, and newly approved ‘tar-geted radionuclide therapy (TRT)’ with [177Lu]DOTATATE, are the only curative options for patients with NETs. TRT is limited to pa--tients that have high levels of somatostatin receptor subtype 2 (SSTR2) and can im-prove the survival of patients with low-grade tumors, but has little effect on high-grade NETs that express low SSTR2 ...

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...

Background: Immune checkpoint inhibitors (ICI) targeting cytotoxic T-lymphocyte-associated protein 4 (CTLA-4), programmed cell death protein 1 and its ligand (PD-1/PD-L1) are the current standard-of-care for many advanced cancers (1). This novel therapeutic approach comes with its costs in the form of immune-related adverse events (irAE). The underlying mechanisms are not yet fully understood. We explore the role of HLA in endocrinopathy related to ICI therapy using an interes...

Background: Cystic fibrosis (CF) is a genetic disorder in which a dysfunctional cystic fibrosis transmembrane regulator (CFTR) chloride channel can result in multimorbidity, including severe respiratory disease and reduced pancreatic exocrine secretion and diabetes. Recently, CFTR modulator therapy, has emerged with the potential of improving respiratory function and remission of diabetes. The effect of CFTR modulator therapy on pancreatic function in patients without preexist...

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...

PARADIGHM™ is a global registry (NCT01922440) of patients diagnosed with hypoparathyroidism (HPT) ≥6 months regardless of aetiology and management. Routine medical care data were entered using electronic case report forms; the 36-item Short Form Health Survey was completed by patients. Baseline-recorded data are reported for 492 patients enrolled as of 1 December 2016 from 41 centres. At baseline, 78% were women, mean (S.D.) age was 49 (17)...
