Introduction: The biological rhythm pattern is synchronized through circadian oscillation of cortisol and melatonin release. Increased cortisol levels and circadian rhythm disruption act as an oncogenic factor in endometrial cancer through among others- dysregulation of cell proliferation/apoptosis and invasion.Aim: To investigate, whether there is an oscillatory expression of the clock genes, MT1 and GR expression in human endometrial carcinoma cells. T...

Background: Obesity is a common risk factor for obstructive sleep apnoea (OSA) and polycystic ovary syndrome (PCOS).Objective: To examine the prevalence of OSA in women with PCOS.Search sources: Electronic databases [Medline, Embase, Cinahl, PsycInfo, Scopus, Web of Science, Opengrey, and Cochrane Central Register of Controlled Trials], conference abstracts, and reference lists of relevant articles. The...

Background: Sporadic and familial autosomal dominant non-autoimmune hyperthyroidism (S/FANH) is caused by activating germline mutations in the TSH Receptor (TSHR) gene. These patients lack TSHR-Ab, show diffuse uptake on radionuclide thyroid scan and often lack positive family history due to variable penetrance. Because of these overlapping features, S/FANH is difficult to distinguished from Graves’ disease without autoimmune features. Ther...

Introduction: Use of supplements (VDS) and vitamin-D measurements have been rising in the recent past globally. Despite increasing intake, our observations reveal that a large percentage of the population remains deficient (VDD). We designed the present real-world study, to address this controversy.Methods: We collected data from patients attending our clinics between March 2014 and December 2022. We recorded our subjects’ gender, age, history of VD...

Introduction: Chronic lymphocytic thyroiditis is an important risk factor for differentiated thyroid cancer (DTC) in surgical series, but the role of thyroid peroxidase antibodies (TPO) seems less clear in that regard. We designed the present study to evaluate that effect in our large patient population. Methods: We recruited subjects operated with total thyroidectomy in 4 sites (USA: 1, Greece: 3) during a period of 14 consecutive years. We gathered dat...

Introduction: Hashimoto’s thyroiditis raises the risk for thyroid cancer (TC) in surgical series, but the role of thyroid peroxidase antibodies (TPO) remains controversial in that regard. We designed the present study to evaluate the effect of preoperative TPO titers in the risk of DTC.Methods: A comprehensive search was conducted in PubMed, CENTRAand Scopus databases in November 2021 for the terms “thyroid cancer” and “TPO” or &...

Endocrine disrupting chemicals (EDCs) are environmental chemicals/toxicants that humans and wildlife are exposed to and which interfere with the action of hormones. Bisphenol A (BPA) is classified as an EDC with xenoestrogenic activity and is recognized by the WHO as a chemical with potentially potent effects on humans throughout different phases of development. A significant knowledge gap still exists regarding the complete spectrum of BPA-induced effects on human physiology,...

Introduction: Diseases of the gastrointestinal tract may have on effect on bone quality manifesting either as osteomalacia or as osteoporosis. Gastritis may have an effect on bone as it requires long term treatment with proton pump inhibitors. Gastrointestinal neoplasms may be accompanied by nutrient malabsorption. These diseases may also be related with vitamin D deficiency.Aim: The aim was to describe two cases of gastrointestinal diseases, namely chro...
