Habitual post-prandial absorption of saturated fatty acids (SFAs) increases systemic atherogenic lipoproteins and a pro-inflammatory response, a condition exacerbated by obesity, insulin resistance (IR) and type 2 diabetes mellitus (T2DM). Also, gut derived bacteria (endotoxin) is absorbed coupled to damaging lipoproteins as it crosses the mucosa, which could directly impact on adipose tissue, as our previous studies suggest. The current studies addressed whether a SFA rich me...

Background: Endoplasmic reticulum (ER) stress in adipose tissue (AT) is critical to the initiation and integration of inflammation and insulin signalling pathways in obese and type 2 diabetes mellitus (T2DM) patients. It induces an unfolded protein response (UPR) to restore functional integrity which leads to upregulation of three master regulators of ER; PKR-like ER-regulated kinase (PERK), inositol requiring enzyme1α (IRE1α) and activating transcription factor6 (AT...

Introduction: Adult patients with craniopharyngioma (CP) and hypothalamic (HT) damage have impaired cognitive function. The white matter (WM) changes behind these findings remain to be elucidated. Diffusion tensor imaging (DTI) is a MRI technique that quantifies microstructural damage in the WM. This is the first study of DTI, hippocampal (HC) and HT volume in relation to cognition in CP patients.Methods: A cross-sectional study of childhood onset CP was...

Background: In acromegaly, few in vivo data exist on changes of the brain parenchyma as a pathology caused by systemically elevated levels of GH and IGF-1. This is in contrast to neuropsychiatric symptoms such as depression, cognitive impairment, personality changes and pain syndromes that accompany the condition. We aimed at measuring brain tissue volumes and white matter pathology in acromegaly.Methods: Forty-three patients (age 54±14 years...

Introduction: Somatostatin analogues (SSA) are a cornerstone in the treatment of neuroendocrine tumours. Two clinical trials have defined the disease control effect of these treatments; the PROMID study of Octreotide LAR v’s placebo, median time to tumour progression (TTP) 14.2 m v’s 6.0 m, and the CLARINET study (Lanreotide v’s placebo), median progression free survival (PFS) 31 m v’s 18 m. In every day practice, however, many neuroendocrine tumours commen...

Background: Androgen deprivation therapy (ADT) for prostate cancer (PCa) leads to a global loss of lean mass. ADT leads to sexual dysfunction and a selective loss of leg muscle function, however individual muscle volumes have never been evaluated. We aimed to assess in men undergoing ADT, the muscle volumes of levator ani, which in mice is androgen-responsive, and of lower-limb muscles.Methods: We conducted a prospective case-control study involving 34 m...

Introduction: FKBP5 is a protein that regulates glucocorticoid receptor sensitivity, via an ultra-short negative feedback mechanism. Variations in the FKBP5 gene can influence the response to glucocorticoids (GC). Hypercortisolaemia plays a role on impairment of brain function and could be mediated by epigenetic variations of the FKBP5 gene. Cushing’s syndrome (CS), a disease characterized by hypercortisolaemia, is associated with memory deficits, lower ...

Introduction: Bile acid (BA)-feeding and genetic manipulation of BA receptors affect glucose tolerance in rodent pregnancy. In non-pregnant individuals, serum BA profiles depend on BMI and ethnicity. The interaction between serum BAs, ethnicity, and BMI in gestational diabetes mellitus (GDM) remains poorly understood.Methods: Fasted serum samples were collected between 23-31 weeks’ gestation. Experimental groups: lean or obese women of European (EU)...

Family history of thyroid disease (Karger 2010) and family history of goiter (Singer 2011, Knudsen 2003, Gebremichael 2020) were found to be associated with risk of goiter though some did not observe this association (Phitayakorn 2006). On participants of the Isparta Menopause and Health (IMH) Study, we measured TSH (n=1099) and thyroid sonographic parameters (n=994) including TV, thyroid nodularity (TN) and heterogeneity (TH). Health related factors and hist...

Introduction: Hyperprolactinemia has been associated with dyslipidaemia, hypercoagulability, impaired endothelial function and decreased insulin sensitivity. Recent data show that prolactin hormone (PRL) could contribute to atherogenesis. The aim of our study was to investigate the relationship between MPV and PRL, androgen hormones, lipid profiles in premenopausal prolactinoma patients, who did not have insulin resistance (IR).Methods: Thirty-nine newly...
