Objectives: To date, there has been no population-wide data looking at the adherence to published TUS reporting guidelines for thyroid nodule malignancy risk assessment. In our health care region in 2018, two radiology groups worked closely with endocrinologists to improve the quality of their TUS reports by adhering to the 2015 ATA or the 2017 TIRADS guidelines. We aim to present the improvement in TUS reports quality with these dedicated changes.Method...

Congenital imprinting disorders (IDs) are a group of rare conditions affecting growth, metabolism and development caused by aberrant expression of imprinted genes in a parent-of-origin dependent manner. The internationally recognised IDs are Prader Willi Syndrome (PWS), Angelman Syndrome (AS), Beckwith Wiedemann Syndrome (BWS), Silver Russell Syndrome (SRS), Temple Syndrome (TS14), Pseudohypoparathyroidism (PHP), Transient Neonatal Diabetes Mellitus (TNDM) and Kagami-Ogata Syn...

Measurement of steroid metabolites in urine by gas chromatography-mass spectrometry remains the gold standard for biochemical diagnosis of steroidogenic disorders. In the UK, three laboratories offer steroid profiling for routine clinical testing, with the Supraregional Assay Service at King’s College Hospital being the largest and experiencing increased demand year-on-year for testing. In this study, we used our profiling database to audit 2021 workload. By direct compar...

Background: More than 12,000 people in the United States are diagnosed with a NET each year and approximately 175,000 people are living with this diagnosis. Little progress has been made in the therapy of NETs over the last two decades, and identification of new vulnerabilities remains a priority.Methods: We used two libraries of compounds selected for potential repurposing and identified agents with the highest cytotoxic activity in neuroendocrine model...

Background: Polycystic ovary syndrome (PCOS) is a prevalent and multifactorial endocrine disorder, characterized by reproductive and metabolic alterations. However, the mechanisms that contribute to the development of metabolic abnormalities are not completely understood. Interestingly, women with PCOS show changes in folate and homocysteine levels suggesting an altered folate metabolism, which could be associated to changes in the methylation patterns of metabolic genes. Meth...

Aims and objectives: Continuous subcutaneous insulin infusion (CSII) has been in clinical practice since 1970s. NICE guidance (2008) recommends CSII in adults with type 1 diabetes (T1DM) if attempts to achieve target HbA1c with multiple daily injections (MDIs) result in disabling hypoglycaemia or HbA1c levels remain above 69 mmol/mol. The aim of our audit was to check compliance of our service against NICE guidance, and to see if CSII improved glycaemic control and/or hypoglyc...

Our large tertiary hospital-based diabetes service high HbA1c policy selects Children and Young People (CYP) with HbA1c above 64 mmol/mol for additional support. Two-week average blood glucose (ABG) is utilised in the high HbA1c clinic as a proxy for HbA1c and CYP are encouraged to reduce their 2 week ABG as a primary goal.Aims: To determine the relationship between HbA1c, 2 week and 3 month ABG and standard deviation (S.D.) in CYP with Ty...

Pheochromocytomas and paragangliomas (PPGL) are rare neuroendocrine tumors derived from chromaffin cells of the adrenal medulla and paraganglia of the autonomic nervous system, respectively. Despite a common origin, these tumors are quite heterogeneous in terms of driver mutations, copy number alterations and activated downstream-signaling pathways. Genome wide expression analysis has identified at least three main tumor clusters: a pseudo-hypoxic cluster, one with activation ...

Introduction: Osilodrostat is a potent oral 11β-hydroxylase inhibitor currently in Phase III clinical development for the treatment of Cushing’s syndrome (CS). The key pharmacokinetic (PK) properties, drug–drug interactions (DDIs), and population PK findings for osilodrostat in humans are summarized.Methods: Osilodrostat PK has been characterized in nine Phase I studies (healthy subjects and subjects with hepatic or renal impairment), two ...

Background: Residual morbidity in patients with Cushing’s syndrome (CS) in remission significantly affects Quality of Life (QoL). While sustained muscle weakness is a frequent complaint in these patients, the impact of muscle dysfunction on their psychophysical wellbeing is currently unknown. Patients & methods: We included 28 female patients [mean(±SD) age, 50±12 years; mean (±SD) BMI, 26.7±3.8] and 26 age- and BMI-matched healthy controls. Mean (...
