The Impact of Age and Sex on Fasting Plasma Glucose and Glycated Haemoglobin (HbA1c) in the Non-diabetes Population.

Introduction: We previously reported sex differences in the distribution of glycated haemoglobin (HbA1c) for men/women aged < 50 years vs older individuals, with implications for delayed diabetes diagnosis. Here, we explored whether this pattern was also seen in matched fasting plasma glucose (FPG) levels.

Methods: We extracted data on same-day, paired HbA1c and FPG levels from clinical biochemistry laboratory databases from Mersey and West Lancashire Teaching Hospitals NHS Trust (n = 10,153) and Cambridge University Hospitals NHS Foundation Trust (n = 10,022) between Jan 2019 and Dec 2023.

Co-designing a virtual reality exposure therapy with students experiencing school anxiety: a proof-of-concept study.

Background And Objectives: Anxiety related school avoidance can affect up to 5% of a country's students each year. VRET (Virtual Reality Exposure Therapy) is a novel therapy proven to be as effective as conventional approaches for treating many anxiety disorders. The aim of this research is to co-design and evaluate a VRET intervention for students experiencing school related anxiety.

Is the Current Cut Point for Glycated Haemoglobin (HbA1c) Correct for Diagnosing Diabetes Mellitus in Premenopausal Women? Evidence to Inform Discussion.

Introduction: Women are on average diagnosed with diabetes mellitus at later age than men but have higher mortality. As the diagnosis of diabetes mellitus is primarily based on HbA1c, the use of a non-specific reference range and cut point for diabetes mellitus that does not account for gender differences in diabetes could potentially lead to underdiagnosis of diabetes mellitus in women and missed opportunities for intervention. We investigated whether a contributing factor to the later diagnosis in women may be a difference in distribution of HbA1c in premenopausal women versus men of the same age by comparing HbA1c values in men and women across multiple sites in the UK.

Serum cortisol assay performance following the 1 mg overnight dexamethasone suppression test.

Background: The 1 mg overnight dexamethasone suppression test (ONDST) is recommended for the differential diagnosis of Cushing's syndrome and the investigation of adrenal incidentalomas. Despite documented variation in serum cortisol immunoassay performance, little has been published regarding its effect on the ONDST.

Aims: Assess the performance of three immunoassay platforms (Roche Elecsys II, Abbott Alinity & Siemens Centaur) when compared to a liquid chromatography tandem mass spectrometry (LC-MS/MS) method.
