Salivary Testosterone, Androstenedione and 11-Oxygenated 19-Carbon Concentrations Differ by Age and Sex in Children.

Background: The diagnosis and management of childhood adrenal disorders is challenging. Clinical markers of hormone excess or deficiency may take months to manifest, and traditional biomarkers correlate only partially with clinical outcomes. Recent work has indicated that 11 oxygenated 19-carbon (11oxC19) steroids may be useful in the assessment of adrenal function.

Adverse Cardiovascular Risk Profile and Increased Diurnal Salivary Cortisol in Girls With Turner Syndrome: An Exploratory Study.

Patients with Turner Syndrome (TS) and those exposed to high concentrations of glucocorticoids have a number of characteristics in common, including an increased risk of cardiovascular disease. Pediatric TS patients underwent studies of salivary cortisol (SC) and cortisone (SCn), body composition, continuous glucose monitoring, vascular function, and ambulatory blood pressure (BP). Biochemical indicators of cardiovascular risk were also measured.

Rapid and non-invasive analysis of paracetamol overdose using paper arrow-mass spectrometry: a prospective observational study.

Background: Paracetamol is the most consumed medicine globally. Its accessibility contributes to common overdose. Paracetamol overdose is responsible for > 50% of acute liver failure cases, making it the second most common reason for a liver transplant.

Urinary Protein Array Analysis to Identify Key Inflammatory Markers in Children with IgA Vasculitis Nephritis.

Chronic kidney disease is a recognised complication of immunoglobulin A vasculitis, (IgAV; formerly Henoch-Schonlein purpura-HSP). The pathophysiology of IgAV and why some patients develop significant renal involvement remains largely unknown. Identifying urinary inflammatory markers could direct targets for earlier intervention.
