Objectives: The metabolic syndrome (MetS) is a cluster of cardiovascular risk factors associated with high cardiovascular morbidity and mortality. The MetS and its elements have been linked to anxiety and depressive disorders. The aim of the current cross-sectional study was to assess the prevalence of depression and anxiety, measured by the Zung Self-Rating Scale in subjects with and without the metabolic syndrome and diabetes.

Unlabelled: Osteoprotegerin (OPG) and osteocalcin (OC) are essential bone proteins. Recent studies have demonstrated that they are not secreted solely by bone cells; they play roles in the vascular function and energy metabolism, and they are influenced by multiple factors. The aim of the current study was to investigate the influence of menopause and age on OPG and OC in women with different thyroid-stimulating hormone (TSH) levels.

Background/objectives: To study the relationship of winter 25-hydroxycholecalciferol (25-OHD) levels with age, education, place of residency, marital status and body mass index (BMI) as they may affect sun exposure, vitamin D synthesis and metabolism.

Subjects/methods: Subjects (1952) answered a structured questionnaire concerning education, marital status and smoking; and body weight/height, and parathyroid hormone and 25-OHD were measured.

Results: 25-OHD levels were higher in the males with elementary and secondary education compared with higher education (46.

Unlabelled: The AIM of the present study was to explore the level of depression in the respondents using the Zung self-rating depression scale (SDS) and find a correlation with the levels of the thyroid-stimulating hormone (TSH) and the anti-thyroid peroxidase antibodies (anti-TPO), the age and gender of the participants.

Patients And Methods: 2401 subjects aged 20-84 yrs were included, 1344 of them female aged 48.7 +/- 14.

Unlabelled: Anti-thyroid antibodies and thyroid ultrasound (US) are currently the methods for diagnosing autoimmune thyroid disease. Few data exist on their utility in males. The aim of the study was to investigate the gender-specific relationship between the Anti-TPO levels, thyroid ultrasound features, and thyroid function in a population with no known thyroid disorder.

Aim: To evaluate the performance of FINDRISC as a screening tool for prediabetes - impaired fasting glucose (IFG) and impaired glucose tolerance (IGT) and undetected diabetes (UDD) in subjects at risk of developing diabetes.

Subjects And Methods: 2169 subjects with at least one risk factor for diabetes completed the FINDRISC questionnaire and underwent an oral glucose tolerance test. FINDRISC performance was assessed using the area under the receiver operating characteristic curve (AUC-ROC).

Aim: To evaluate cardiovascular risk in prediabetes (IFG and IGT) assessed by serum lipid and hsCRP levels.

Subjects And Methods: 445 subjects with prediabetes (248 with IFG, 197 with IGT), 318 patients with newly-diagnosed diabetes (NDD) and a group of 477 age- and BMI-matched subjects with normal glucose tolerance (NGT) were enrolled. Glucose tolerance was studied during oral glucose tolerance test (OGTT) and 2006 WHO criteria were applied.

Menopause is associated with two main risk factors for the development of type 2 diabetes mellitus--impaired beta-cell insulin secretion and insulin resistance. Physiologically estrogens improve carbohydrate metabolism, but this is not the case with different progestogens. The aim of the present study was to evaluate the effect of Cyproterone acetate (a progestogen with antiandrogenic activity) on insulin secretion, peripheral insulin sensitivity, lipid parameters and parameters of oxidative stress.

Background: Recently the pathophysiological role of endothelin (ET) has been presumed in a number of adrenal disorders such as primary hyperaldosteronism, pheochromocytoma and adrenocortical insufficiency.

Aim: The aim of the present study was to evaluate circulating ET-1 levels in patients with endogenous Cushing's syndrome.

Methods And Results: Plasma ET-1 levels were determined by highly sensitive RIA.

The effect of repaglinide on insulin secretion and oxidative stress was evaluated in type 2 diabetic patients in a randomized, controlled, open-label trial. Forty-six patients were treated for 2 months with repaglinide, added to either diet (n=21) or metformin (n=25). A control group of 29 patients, matched for age, weight and glycaemic control, on either diet (n=13) or metformin (n=16) was also followed-up.
