Patients with sellar masses (SM) undergoing transsphenoidal surgery (TSS) have a significant risk of transient or permanent endocrine dysfunction; therefore, in-hospital endocrinology consultation (IHEC) is recommended for these patients. However, routine assessment of all TSS patients by a specialized team is not feasible outside select centers. We developed an IHEC guide for TSS patients in December 2015 to identify those patients who would require perioperative IHEC. We con...

Introduction: Leptin is a well-known adipokine which has a critical role in the regulation of body weight, body fat mass, appetite, and food intakes. Energy-supplying nutrients such as carbohydrates is a dietary-related factor which has potential effects on plasma leptin levels. The effect of habitual carbohydrates intake on leptin gene expression was limited only in animal studies. The current study aimed to investigate the association of habitual carbohydrate intake with lep...

Introduction: Trials on children and adolescents with excess weight are limited and lack parathyroid hormone (PTH) measures as a surrogate marker of vitaminD status in skeletal health. The present study addresses this key knowledge gap with the use of a dose-response randomized clinical trial (RCT) aimed at determining vitamin D requirement to increase 25(OH)D and suppress PTH concentrations in overweight and obese school children.Methods: The current st...

Background and aim: The 25OHD concentration at which intact parathyroid hormone (iPTH) is maximally suppressed and below which PTH begins to rise (inflection point) has been used to define optimum 25OHD concentration. While it is not known if the lower 25OHD levels in obese children are associated with a PTH increase in the same manner as it is in normal weight children, we aimed to study the relation between circulating PTH and 25OHD levels and to search for a 25OHD threshold...

Background and aim: Apelin, as an adipokine, is encoded by the APLN gene. It is a key regulator in glucose and lipid metabolism and plays an important role in the pathogenesis of insulin resistance and type 2 diabetes. It seems that habitual dietary intake of carbohydrates including quality and quantity by chronic manipulating insulin concentration might have a distinguishing role in the prediction of apelin gene expression in adipose tissue, but there is no evidence in this r...

Introduction: Human fat mass and obesity-associated gene (FTO) gene expression are associated with body mass index and type 2 diabetes. It is unknown whether lifestyle factors, such as physical activity, can attenuate weight gain and obesity by contribution to the FTO gene regulation. The objective of the present study was to investigate the association between habitual physical activity and the FTO gene expression among morbid obese and non-obese subjects.<p class="abstex...

Objective: To highlight an unusual cause of hyperinsulinaemic hypoglycemiaMethods: Case Report: Results or Case PresentationA previously healthy and fit 52 year old gentleman of Asian descent presented with recurrent severe neuroglycopenic hyperinsulinemic hypoglycemic symptoms, suggestive of insulinoma. On several occasions he was confirmed to have severe hypoglcaemia with venous blood glucose values ranging between 1.5 and 2.7 mm...

Introduction: Polycystic ovary syndrome (PCOS) is the most common endocrinopathy in women in reproductive age. A condition that causes irregular menstrual periods because monthly ovulation is interrupted and levels of androgens are elevated. It occurs in about 5–10% of women and is considered to be the most common cause of anovulatory infertility in reproductive age.Objectives: To compare the prevalence, levels of thyroid auto-antibodies in a group ...

New evidence indicated that miRNAs may contribute to the regulation of energy balance and metabolic homeostasis, by controlling a wide range of metabolic pathways. miR-143 and miR-34a are the best studied among the miRNAs linked to adipose tissue regulation. Dietary intake, among many other environmental factors, is a key player that can induce epigenetic changes. The aim of the study was to investigate the association of the miR-143 and miR-34a expression in visceral and subc...

Adipose triglyceride lipase (ATGL) and hormone-sensitive lipase (HSL) are key enzymes involved in intracellular degradation of triacylglycerols. The environmental factors and circulating biomarkers can affect the expression of ATGL and HSL in adipocytes among rats. To our knowledge, however, no information is known about the dietary and plasma fatty acids composition on gene expression of ATGL and HSL in human adipose tissue. We aimed to determine how fatty acid species measur...
