Muscle wasting is a common feature of inflammatory myopathies. Glucocorticoids (GCs), whilst effective at suppressing inflammation and inflammatory muscle loss, also cause myopathy with prolonged administration. 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1) is a bidirectional GC activating enzyme, potently up-regulated by inflammation within mesenchymal derived tissues. We assessed the regulation of this enzyme with inflammation in muscle and examined its functi...

Background/Aim: Radioactive-iodine (RAI) therapy aims to cure hyperthyroidism, with some International authorities recommending a sufficient RAI dose to render patients hypothyroid. An audit on low dose RAI (<400 MBq) at our University Hospital in 2014 suggested above national average rates of Thyrotoxicosis relapse (24%) and lower rates of hypothyroidism (41%) 6-months post RAI. From 2015, a fixed dose (555 MBq) RAI was utilised and we present the audit outcomes using thi...

Both therapeutic glucocorticoids (GCs) and chronic inflammation are powerful inducers of systemic bone loss, resulting in osteoporosis and increased morbidity. Whilst GCs suppress inflammation, it is unclear how these factors interact to determine net bone metabolism. We investigated the balance between osteo-protective and osteo-destructive properties of GCs in the TNF-tg model of chronic inflammatory disease. Wild-type (WT) and TNF-tg mice were treated with corticosterone (1...

Aim: Cinacalcet is a useful treatment option in primary hyperparathyroidism (PHPT) who are managed conservatively; however there are licensing issues and challenges for prescribing in primary care. The aim of our study was to assess the efficacy of cinacalcet treatment in PHPT and benefit of admission avoidance.Methods: Data on patients treated with cinacalcet for PHPT were analysed. PTH, adjusted calcium and vitamin D at initiation, calcium at 6 and 12 ...

Diabetes mellitus (DM) is associated with an increased risk of fractures in excess of what would be expected from age and BMD. Further, DM is associated with increased risk of mortality in patients with hip fractures and possibly also other osteoporotic fractures.Study population and methods: Patients aged 50 or over who were treated for fractures of the hip, forearm, humerus and spine over 6 years (2004–2009, n=146 256) not coded as road t...

Background: Presently it is unknown how much of testosterone decline associated with aging is actually due to ageing per se, and how much is related to weight gain, decreased activity, and other age-related factors. Understanding the modifiable factors associated with low testosterone, such as obesity or cardiorespiratory fitness (fitness) is critical.Methods: The observational, cross-sectional study included 1653 men, ≥50 and <80 year...

Background: Children who are overweight and obese have a higher incidence of fracture, but it is unknown if this varies by fracture site. Indeed, obesity in adult women protects against forearm fracture, but increases the risk of humeral fractures. We aimed to determine if adiposity differed by fracture site in children with upper limb fractures.Methods: Children aged 3–18 years were recruited within 60 days of fracture. Height, weight, waist circum...

Introduction: HbA1c is an important quality indicator when benchmarking diabetes clinics. Systematic error in the measurement of HbA1c could result in inappropriately high or low values, and if not corrected give a wrong impression of the standard of care.Methods: We included data on HbA1c from the Norwegian adult diabetes register on 3,854 type 1 diabetics attending 13 hospital clinics. Correction factors for HbA1c were derived from the results of the l...

Objective: Early postoperative results for the Preoperative Octreotide Treatment of Acromegaly (POTA) study has been published, and like later randomized studies we demonstrated a beneficial effect of presurgical treatment with somatostatin analogues (SSA) in GH-secreting macroadenomas when evaluated 3–4 months postoperatively. However, concerns about a potential lingering effect of SSA and thereby potential false positive results have been raised. The objective of this s...

Aim: Nutritional abnormalities are common after bariatric surgery and it is vitally important to assess and replace them pre-operatively to ease management post-operatively. The aim of our study was to assess the prevalence of various metabolic abnormalities at first visit to a tertiary combined bariatric endocrine clinic.Methods: Data was collected on 200 patients referred for consideration of bariatric surgery. Being a retrospective analysis and theref...
