Do near-infrared intra-operative findings by the use of indocyanine green correlate with post-thyroidectomy parathyroid function? - the ICGPREDICT study

Papavramidis Thedosios , Anagnostis Panagiotis , Chorti Angeliki , Pliakos Ioannis , Panidis Stavros , Koutsoumparis Dimitris , Michalopoulos Antonios

Background/Aims: Post-operative hypoparathyroidism still remains a significant complication after thyroidectomy. Intraoperative imaging modalities, such as near infrared fluorescence by the use of indocyanine green (ICG), may assist to identify and preserve the parathyroid glands (PGs). The purpose of this study was to test the association between intra-operative ICG staining scoring system and 24-h post-operative parathyroid hormone (PTH) levels, as well as its capability of ...

Serum concentrations of carboxylated osteocalcin are increased and associated with the components of the polycystic ovarian syndrome

Diamanti-Kandarakis Evanthia , Livadas Sarantis , Katsikis Ilias , Piperi Christine , Mantziou Aimilia , Papavassiliou Athanasios G , Panidis Dimitrios

Objective: Intriguing studies suggest that osteocalcin (OC) and its carboxylated (Gla)/uncarboxylated form are involved in the regulation of insulin secretion and action. Additionally, advanced glycated end products (AGEs), directly regulate the secretion of these osteoblast derived molecules. In PCOS among the pathophysiological aberrations, deregulation of insulin secretion and action as well as elevated AGEs levels have been demonstrated. In this study, we evaluated the ser...

Advanced glycosylated end products are associated with anovulatory markers in women with polycystic ovary syndrome

Diamanti-Kandarakis Evanthia , Piouka Athanasia , Livadas Sarantis , Piperi Christine , Katsikis Ilias , Papavasiliou Athanasios , Panidis Dimitrios

Background: Chronic anovulation constitutes one of the cardinal features of Polycystic Ovary Syndrome (PCOS) and Anti-Müllerian hormone (AMH), a granulosa cell product, is a well documented marker of anovulation. Recent data have shown that oxidative stress is involved in the pathophysiology of anovulation. A marker of oxidative stress, Advanced Glycosylated End products (AGEs), is implicated to the pathogenesis of the syndrome and have been localized with high intensity ...

A systematic review and a meta-analysis on adiponectin levels in women with polycystic ovary syndrome

Toulis Konstantinos , Goulis Dimitrios , Farmakiotis Dimitrios , Katsikis Ilias , Georgopoulos Neoklis , Tarlatzis Basil , Papadimas Ioannis , Panidis Dimitrios

Background: Conflicting results regarding adiponectin levels in women with polycystic ovary syndrome (PCOS) have been reported. To evaluate adiponectin levels in PCOS, a systematic review of all studies comparing adiponectin levels in women with PCOS to healthy controls and a meta-analysis of those involving women with similar Body Mass Index (BMI) were performed. Influence of possible effect modifiers, such as insulin resistance (IR) and testosterone, was investigated. Influe...

Increased serum AGEs is a distinct finding in lean women with PCOS

Diamanti-Kandarakis Evanthia , Katsikis Ilias , Piperi Christina , Kandaraki Eleni , Piouka Athanasia , Papavassiliou Athanasios , Panidis Dimitrios

In insulin resistant, young women with PCOS elevated serum AGEs and their receptor RAGE have been reported. The present study (approved by the local ethical committee) was undertaken to determine whether increased levels of serum AGEs in PCOS is a distinct finding compared with age- and BMI-matched women, presenting the isolated components of the syndrome and whether serum AGE levels were different among PCOS phenotypes. A total of 193 lean non-insulin resistant women were stu...

Relation of proatherogenic lipid profile and insulin resistance in PCOS

Macut Djuro , Panidis Dimitrios , Glisic Biljana , Spanos Nikolaos , Petakov Milan , Bjekic Jelica , Bozic Ivana , Damjanovic Svetozar

Polycystic ovary syndrome (PCOS) is a common reproductive endocrine disorder. The metabolic aspect of disorder is characterized by obesity-related risk factors for cardiovascular disease. The aim of this study was to determine in women with PCOS, indices of lipid metabolism and their oxidation, and to assess possible relation to insulin resistance. We investigated 75 women with PCOS (age: 23.1±5.1 years, body mass index (BMI): 24.9±4.7 kg/m2) and 56 age an...

Endothelin-1 levels in men of reproductive age with idiopathic hypogonadism after treatment with tamoxifen or raloxifene

Tzoitou M , Papadopoulou E , Papageorgiou A , Kita M , Zournatzi V , Kourtis A , Avramidis A , Panidis D

An association between testicular function and vasoconstrictive peptide endothelin-1 levels, which is produced by Leydig and Sertoli cells, is observed. Endothelin –1 regulates blood flow in the testis and stimulates testosterone secretion.The purpose of this study is (1) to estimate the influence of tamoxifene and raloxifene therapy on enthothelin-1 levels in men of reproductive age with idiopathic hypogonadism. (2) To find an association between i...

The relation of liver enzymes and insulin resistance in women with polycystic ovary syndrome (PCOS)

Macut Djuro , Bozic-Antic Ivana , Tziomalos Konstantinos , Bjekic-Macut Jelica , Ilic Dusan , Vojnovic-Milutinovic Danijela , Stanojlovic Olivera , Panidis Dimitrios

Introduction: There is a link between polycystic ovary syndrome (PCOS) and nonalcoholic fatty liver disease (NAFLD). Here, we analyzed transaminazes and their relation to insulin resistance (IR) in PCOS women.Methods: We analyzed 600 women with PCOS diagnosed using ESHRE/ASRM criteria (age:25.6±5.9 years, BMI: 30.6±6.9 kg/m2), and 125 BMI-matched healthy controls (age: 31.4±5.3 years, BMI: 29.6±6.8 kg/m2). IR was...

AMHR2 polymorphism and risk for polycystic ovary syndrome: relationship to gonadotropin levels

Georgopoulos Neoklis , Karagiannidou Eleni , Koika Vasiliki , Roupas Nikolaos , Armeni Anastasia , Marioli Dimitra , Papadakis Efstathios , Welt Corine , Panidis Dimitrios

Introduction: The polycystic ovary syndrome (PCOS) is a common and complex disease without a clear pattern of inheritance. There is evidence that PCOS is affected by both genetic and environmental factors, but there is no single and unambiguous explanation for its pathogenesis. Anti-Müllerian-inhibiting hormone (AMH) has an inhibitory effect on FSH-stimulated follicle growth and it has also been shown that serum AMH levels are higher in women with PCOS than in normovulato...

Effect of pharmaceutical intervention on serum levels of advanced glycated end products in women with polycystic ovary syndrome

Diamanti-Kandarakis Evanthia , Christakou Charikleia , Piperi Chistina , Kandaraki Eleni , Katsikis Ilias , Adamopoulos Christos , Papavasiliou Athanasios G , Panidis Dimitrios

Background: Polycystic ovary syndrome (PCOS) is associated with obesity and insulin resistance, two major contributors to cardiovascular risk. Even in the absence of detectable insulin resistance, lean, non-diabetic PCOS women demonstrate increased circulating levels of advanced glycated end products (AGEs), known proatherogenic molecules. This adverse cardiovascular risk profile should be considered in the syndrome’s management.Objective: To invest...
