69-year old male was diagnosed with non-secreting pituitary macroadenoma (25x 15x 15mm) in 2008. Patient underwent two transsphenoidal surgeries and stereotactic radiotherapy in 2008 and 2009. Tumor recurrence was noticed on MRI in 2016. In 2017 urgent right pterional craniotomy was performer due to right eyelid dropping with ocular nerves palsy. Despite surgery further growth of the tumor (32x 22x 31mm) was reported in 2018, followed by increased ACTH level and hypercortisole...

Background: Polycystic ovary syndrome (PCOS) is a condition affecting up to 20% of reproductive-aged women. PCOS is associated with obesity and serious metabolic complications. There is a lack of research evaluating differences in metabolic complications between hyperandrogenic physically active and inactive individuals.Objective: We used a cross-sectional study to compare the risk of obesity, metabolic syndrome, visceral adipose index, and insulin resis...

The Trabecular Bone Score (TBS) has recently been developed through the grayscale textural analysis of Dual-Energy X-ray Absorptiometry (DXA) images. Due to its capability to evaluate the microarchitectural texture of bone, TBS proves valuable in the assessment of bone quality. While the clinical relevance of TBS has been partially confirmed in relation to hormonal disorders, there is currently a lack of precise data regarding its application during specific phases of treatmen...

Acromegaly is characterized by two-fold higher mortality than in the general population. The leading causes of morbidity and mortality in patients with acromegaly are cardiovascular diseases (CVD). Many population-based studies suggest a role of genetic background in CVD and associated metabolic disturbances. In 2007, FTO (fat mass and obesity associated) gene polymorphisms were discovered. According to a few studies, the polymorphisms of FTO gene are associated with ...

Background: Primary aldosteronism (PA) is the most common endocrine cause of secondary hypertension. It occurs in 5%-10% of hypertensive patients. PA is a group of disorders associated with semi-autonomous hypersecretion of aldosterone. Laboratory diagnosis in patients with suspected PA consists of screening tests aimed at determination of serum/plasma aldosterone concentration, direct renin concentration (DRC) and calculation of the aldosterone/direct renin ratio (ADRR). The ...

Objectives: The excessive production of pro-inflammatory cytokines has been previously reported in the severe form of COVID-19. The cytokine storm is responsible for the induction of an inflammatory endothelial cell phenotype which is associated with the shedding of adhesion molecules. VCAM-1 is an endothelial adhesion protein that belongs to the immunoglobulin superfamily. Pro-inflammatory cytokines lead to the induction of VCAM-1 in the endothelium of blood vessels which is ...

Objective: Polycystic ovary syndrome (PCOS) is hypothesized to originate in foetal life, while its long-term consequences extend beyond menopause. However, the natural course of the disorder has not as yet been elucidated, and recent data suggest differences in the evolution of PCOS according to a woman’s weight. We aimed to define the evolution of normal-weight Caucasian women with PCOS through the years.Design: Cross-sectional case control study</...

Glypican-4 (Gpc-4) is novel adipokine interact with insulin receptor and affects insulin sensitivity in proteoglycans. Gpc-4 serum levels show gender differences; females having higher levels than men, what can suggest mediation by sex hormones. We investigated serum Gpc-4 levels and its association with cardiovascular risk predictors in women (20–35 years old) with PCOS (n=62) and healthy control (n=43) presented different sex hormones profile. The foll...

The genetic instability, i.e. loss of heterozygosity (LOH) and microsatellite instability (MSI) are frequent molecular events in thyroid tumour aetiopathogenesis. They were found in several chromosomal critical areas, including 3p12–p21.2, 3p24.2–p25.3, 7q21.1–q31.2, 10q22–24, and 15q11–q13, with loci of oncogenes and tumour suppressor genes.Aim of the study: Evaluation of usefulness of LOH/MSI as diagnostic/prognostic biomarker ...

The search for new differentiating biomarkers in follicular-cell derived thyroid tumors (FCDT), especially for the FNAB with underdetermined cytology, is an important scientific task. Disturbed expression of tumor suppressor genes plays important role in thyroid carcinogenesis. In this study we focused on epigenetic mechanism influencing on trefoil factor 3 (TFF3) and tissue inhibitor of metalloproteinases 3 (TIMP3) expression.Aim of the study: Evaluatio...
