Introduction: The aim of this study was to estimate serum fetuin-A levels in lean and obese women with polycystic ovary syndrome (PCOS) and to find possible relationships between fetuin-A, metabolic factors and androgens in these patients.
Material And Methods: In 25 lean (18-38 years, BMI 17.5-25.0 kg/m2) and 15 obese women (20-41 years, BMI 28.1-53.2 kg/m2) with PCOS, anthropometric indices and body composition were measured. Fasting serum fetuin-A, adiponectin, leptin, glucose, lipids, hsCRP, insulin, androgens and SHGB levels were estimated.
Results: There was no significant difference in serum fetuin-A levels between lean and obese patients: 0.54 ± 0.13 g/L and 0.60 ± 0.14 g/L, respectively. We noted a correlation between BMI and leptin levels (r = 0.88; p < 0.0001) and a nearly significant negative correlation between BMI and adiponectin levels (r = -0.53; p = 0.11) in all subjects. In lean patients, we found a correlation between fetuin-A levels and ALT activity (r = 0.44; p < 0.05). In all participants, fetuin-A correlated directly with DHEA-S levels (r = 0.44; p < 0.03).
Conclusions: Serum fetuin-A levels were similar in lean and obese women with PCOS. We found an association between fetuin-A levels and ALT activity in lean patients and between fetuin-A levels and DHEA-S in all women. The role of fetuin-A in the mechanisms of insulin resistance, and its potential impact on androgenic hormones production in women with PCOS, need to be tested in further studies.

The effect of sevelamer on serum calcification propensity in patients with chronic kidney disease: the results of a multicentre, double-blind, placebo-controlled, randomized clinical trial.

Background: The serum calcification propensity test (or T50 test) might become a standard tool for the assessment of vascular calcification risk and T50 might be a valuable biomarker in clinical trials of treatments intended to slow the progression of vascular calcification. Literature data suggest that non-calcium-containing phosphate binders can influence T50 in chronic dialysed patients. However, it is not clear whether similar interventions are effective in patients at earlier stages of chronic kidney disease (CKD).

Background: Despite existing evidence of the high predictive value of natriuretic peptides (NPs) in patients with heart failure (HF), patients treated with guideline-directed therapy who have low or near-normal NP levels are unlikely to be correctly stratified for risk of clinical outcomes. The aim of this study is to detect plausible predictors for poor one-year clinical outcomes in patients with HFpEF and low NT-proBNP treated with in accordance with conventional guidelines.
Methods: A total of 337 patients with HF with preserved ejection fraction (HFpEF) who had low levels of N-terminal natriuretic pro-peptide (NT-proBNP) at discharge due to optimal guideline-based therapy were enrolled in the study.
Fetuin-A levels in diabetic retinopathy: a systematic review and meta-analysis.

Faculty of Medicine, University of Montenegro, Podgorica, Montenegro.
Background: Diabetic retinopathy (DR) is one of the main microvascular complications of diabetes and one of the most common causes of vision loss worldwide. Fetuin-A is a glycoprotein correlated with insulin resistance and has been measured in DR patients. Herein, we aimed to investigate these studies through a systematic review and meta-analysis.

Aim: Patients with type 2 diabetes mellitus (T2D) are prone to develop vascular calcification. Fetuin-A protects against vascular calcification but it increases insulin resistance. T50 calciprotein crystallization (also called serum calcification propensity) is a novel marker of calcification stress.

Urine samples were systematically collected from inseminated Murrah buffaloes (Bubalus bubalis) on days 0, 7, 14, 21 and 28 (with day 0 representing the day of artificial insemination). Following confirmation of pregnancy via trans rectal palpation 45 days of insemination, the animals were categorised into pregnant and non-pregnant groups (n = 10 each). The urine samples on 0, 7, 14, 21 and 28 days of pregnant and one sample from non-pregnant preferably collected on 28th day was used for SDS-PAGE after diafiltration.
