Introduction: The prevalence of obesity in elderly population increased. Obesity leads to increased morbidity and mortality as well as worsens quality of life in older individuals. Body-mass index (BMI) is the most widely used adiposity index. BMI correlates with body fatness but this index does not account for fat mass versus fat-free mass. Recently a new index of body adiposity the body adiposity index (BAI) was introduced. This novel index correlates well (in comparison to ...

Insulinoma, a rare neuroendocrine tumor (NET), is benign in more than 90% of cases. We present a review of patients diagnosed with insulinoma at our Department.Methods: Retrospective review of clinical records of patients diagnosed with insulinoma between 2011 and 2016.Results: Six female patients were diagnosed with insulinoma (age at presentation 30–66, follow-up: 0.25–3.25 years). Episodes of sweating, palpitations, tr...

Irisin is a recently reported, widely discussed new adipo-myokin secreted mainly by muscle tissue. It is a cleaved and secreted part of fibronectin type III domain containing 5, encoded by the FNDC5 gene. Some of the previously published studies claim that alterations of irisin levels in patients affected by thyroid diseases may be connected mainly with accompanying myopathy. However, to date it has not been evaluated, whether the changes in expression of FNDC5</e...

Abstract: Nicotinamide phosphoribosyltransferase (NAMPT) overexpression was reported in many autoimmune diseases. We have also found NAMPT overexpression in leukocytes of patients with Graves’ orbitopathy. Therefore, we aimed to analyze NAMPT expression level in thyroid gland of patients with Graves’ disease with orbitopathy and without orbitopathy, and in healthy thyroid gland. We have analyzed 80 thyroid tissue samples of patients who underwent th...

Pituitary dysfunction is a common, treatable consequence of traumatic brain injury (TBI), and is associated with poorer outcomes. Identifying prognostic factors that allow targeted endocrine testing will ensure that patients at higher risk of pituitary dysfunction are identified and screened.Analysis of 176 adults at least 6 weeks after TBI attending the multidisciplinary Imperial TBI clinic found an overall prevalence of pituitary dysfunction of 13.7% (...

Perturbations in thyroid function are common in older individuals but their significance in the very old is not fully understood. We examined thyroid hormone status (serum TSH, FT4, FT3, rT3) at baseline in a cohort of 643 85-year-olds and followed their mortality and disability outcomes for 9 years. All cause mortality, cardiovascular mortality and disability according to categorical thyroid disease status and baseline thyroid hormone paramete...

The function of the thyroid gland is to maintain thyroid hormone (TH) levels in the blood circulation. Thyroid epithelial cells liberate TH from the precursor molecule thyroglobulin (Tg) by the combined proteolytic action of the cathepsin B, K, L, and S. Cathepsin L-deficiency in mice results in impaired processing of Tg and remnants of dead cells in the follicle lumen. Recently, we have shown that Trace amine-associated receptor 1 (Taar1) is localized on the primary cilia of ...

Polycystic ovary syndrome (PCOS) and type 1 diabetes (T1DM) are accompanied by increased risk of atherosclerosis. A higher prevalence of PCOS in T1DM patients has been reported. Brachial artery flow-mediated dilatation (FMD) and intima media thickness of common carotid artery (IMT) are used to detect an early endothelial dysfunction.The aim of our study was to examine IMT and FMD in T1DM women with PCOS. We also estimated the relation of IMT and FMD to c...

Cysteine cathepsins are endo-lysosomal proteases that play crucial roles in thyroid physiology. However, in thyroid cancer, cathepsin B is overexpressed and secreted into the extracellular space, thus promoting migratory phenotypes of thyroid carcinoma cells through excessive extracellular matrix degradation. In addition, we have shown that N-terminally truncated forms of cathepsins B and V which lack the signal peptide and parts of the pro-peptide are localized to the nuclei ...

Background: Silver-russell syndrome (SRS; OMIM 180860) is a genetically and clinically heterogeneous low birthweight syndrome characterised by poor postnatal growth and a number of variable dysmorphic features. Small-for-gestational age infants in general have an increased risk of metabolic complications, some initially occurring in late childhood and adolescence.Objective and hypotheses: To identify (a) response to GH based on genotype and (b) developme...
