Background: The level of 25OH vitamin D (25OHD) which separates deficiency from sufficiency is heavily deabted. With decreasing 25OHD levels, typical biochemical derangements set in, such as increasing parathyroid hormone (PTH) and alkaline phosphatase (ALP) levels, and decreasing phosphate and calcium levels. In adults, serum concentrations of PTH reportedly start to rise when serum 25OHD levels drop below 30 μg/l. Such data are scarce in children....

Introduction: Most (89%) UK units offer some form of free patient choice for new paediatric patients commencing GH therapy. Initial data indicates that patient choice improves adherence, resulting in improved growth (height velocity) short-term.Objective: To compare outcome measures between patients offered free choice and/or hospital supply (including home services and adherence tracking assessed using ampoule counting) with GH therapy with those who di...

Glucagon-like peptide-1 receptor (GLP-1R) agonists are effective treatments for type 2 diabetes and obesity. We recently described ‘biased’ peptide GLP-1R agonists modelled on exendin-4 which uncouple the pronounced endocytosis that usually accompanies GLP-1R activation, leading to prolongation of intracellular signalling responses. Here, we show that the metabolic consequences of biased GLP-1R activation in vivo are dominated by improvements in blood glucos...
