A novel method for rapid and quantitative detection of bisphenol A in urine.

Bisphenol A (BPA) is classified as an endocrine disruptor (ED) and it can interact with variety of hormone receptors leading to hormonal disruption and increased risk of various adverse health effects. Reducing human exposure to BPA is one of the main challenges of public health, as it is constantly present in daily life. A low-cost and commonly applied method to enable determination of BPA in the patient's body has yet to be developed.

Serum Vitamin D Binding Protein Level Associated with Metabolic Cardiovascular Risk Factors in Women with the Polycystic Ovary Syndrome.

The objective of the study was to measure the levels of 25-hydroxyvitamin D [25(OH)D] and vitamin D binding protein (VDBP) and assess their relationships with cardiovascular risk factors in women with the polycystic ovary syndrome (PCOS). A group of 267 women, aged 20-35 years (24.7 ± 4.

The polycystic ovary syndrome: a position statement from the Polish Society of Endocrinology, the Polish Society of Gynaecologists and Obstetricians, and the Polish Society of Gynaecological Endocrinology.

Polycystic ovary syndrome (PCOS) diagnosis and therapy still arouse a lot of controversy. Each year brings new information, so, having collected the experience of three scientific societies, we present contemporary recommendations concerning PCOS diagnostics and treat-ment. In adult female diagnosis, we still use the Rotterdam criteria, which is two out of three of the follwing characteristics: a) ovulation abnormality, b) clinical or biochemical hyperandrogenism, and c) polycystic ovaries.

Lipid accumulation product (LAP) as a criterion for the identification of the healthy obesity phenotype in postmenopausal women.

Obesity and its complications constitute a major health problem in postmenopausal women. The identification of the obesity phenotype, especially that of metabolically healthy obese (MHO) patients, is a necessary part of obesity treatment protocols. There are several methods to define MHO, but unfortunately, all of them are arbitrary and inconsistent.

Association of serum glypican-4 levels with cardiovascular risk predictors in women with polycystic ovary syndrome - a pilot study.

Objective: Glypican-4 (Gpc4) is an adipokine which interacts with the insulin receptor and affects insulin sensitivity in proteoglycans. Insulin resistance plays a crucial role in the etiology of polycystic ovary syndrome (PCOS). PCOS is associated with metabolic disturbances such as abdominal obesity, dyslipidemia and type 2 diabetes.

Classic PCOS phenotype is not associated with deficiency of endogenous vitamin D and VDR gene polymorphisms rs731236 (TaqI), rs7975232 (ApaI), rs1544410 (BsmI), rs10735810 (FokI): a case-control study of lower Silesian women.

Context: The role of endogenous vitamin D and vitamin D receptor (VDR) gene polymorphism in polycystic ovary syndrome (PCOS) is still controversial.

Objective: The objective of this study was to investigate for the first time in women with "classic" PCOS phenotype and healthy controls the role of the serum endogenous vitamin D level and VDR gene polymorphisms in PCOS etiology.

Design: Ninety-two women with "classic" PCOS phenotype and 85 controls from lower Silesia with comparable body mass index (BMI) were studied.

Irisin plasma concentration in PCOS and healthy subjects is related to body fat content and android fat distribution.

Irisin (Ir), a recently identified adipo-myokine, cleaved and secreted from the protein FNDC5 in response to physical activity, has been postulated to induce the differentiation of a subset of white adipocytes into brown fat and to mediate the beneficial effects on metabolic homeostasis. Metabolic syndrome (MS), a cluster of factors leading to impaired energy homeostasis, affects a significant proportion of subjects suffering from polycystic ovary syndrome (PCOS). The aim of our study was to investigate the relationship between Ir plasma concentrations and metabolic disturbances.

Polish Society of Endocrinology Position statement on endocrine disrupting chemicals (EDCs).

With the reference to the position statements of the Endocrine Society, the Paediatric Endocrine Society, and the European Society of Paediatric Endocrinology, the Polish Society of Endocrinology points out the adverse health effects caused by endocrine disrupting chemicals (EDCs) commonly used in daily life as components of plastics, food containers, pharmaceuticals, and cosmetics. The statement is based on the alarming data about the increase of the prevalence of many endocrine disorders such as: cryptorchidism, precocious puberty in girls and boys, and hormone-dependent cancers (endometrium, breast, prostate). In our opinion, it is of human benefit to conduct epidemiological studies that will enable the estimation of the risk factors of exposure to EDCs and the probability of endocrine disorders.

Association between vitamin D concentration and levels of sex hormones in an elderly Polish population with different genotypes of VDR polymorphisms (rs10735810, rs1544410, rs7975232, rs731236).

Background: Vitamin D co-regulates the synthesis of sex hormones in part by interaction with its nuclear receptor. The aim of this study was to determine whether there is an association of vitamin D concentration vs the level of sex hormones in elderly Polish individuals with different genotypes of the vitamin D receptor (VDR) gene.

Materials And Methods: Rs10735810, rs1544410, rs7975232, and rs731236 polymorphisms of VDR, the serum sex hormone level, free estrogen index (FEI) and free androgen index (FAI) as well as vitamin D, were evaluated in 766 persons (362 women and 404 men) selected from 5695 Polish population, aged 65-90years from the PolSenior survey.

Accumulation of abdominal fat in relation to selected proinflammatory cytokines concentrations in non-obese Wrocław inhabitants.

Introduction: Metabolically obese normal weight (MONW) subjects, despite their normal BMI, present metabolic disturbances characteristic of abdominal obesity. One of the reasons might be subclinical inflammation caused by the fat tissue excess. The aim of this study was to assess the association between the accumulation of fat (especially abdominal) and the concentration of selected proinflammatory cytokines - interleukins (IL-6, IL-18) and C-reactive protein (CRP).

Non-alcoholic fatty liver disease in women with polycystic ovary syndrome - clinical and metabolic aspects and lipoprotein lipase gene polymorphism.

Introduction: The aim was to assess associations among PCOS and NAFLD, the lipoprotein lipase polymorphism gene, and metabolic disorders in PCOS.

Material And Methods: In 184 women with PCOS and 125 healthy, premenopausal volunteers, sex steroids, lipids, glucose, insulin, aminotransferases, free androgen index (FAI), HOMA-IR and E2/T were calculated. Hepatic steatosis was determined by ultrasound.

ISGE statement on oral emergency contraception.

Unintended pregnancy is an important public health problem worldwide. Unwanted pregnancies may end in induced abortion (legal or illegal, safe or unsafe) or in childbirth. In many parts of the world both can be life threatening.

Vitamin D receptor gene polymorphisms in relation to the risk of colorectal cancer in the Polish population.

The protective effect of vitamin D against several cancers including colorectal cancer is modulated by the vitamin D receptor (VDR) and its ligand, the active form of vitamin D. VDR response has been found to play a role in various genes encoding proteins involved in crucial cellular pathways. Single nucleotide polymorphisms (SNPs) of the VDR gene that modulate its activity are located in the promoter region, exons 2-9, and their vicinity and also in the 3'UTR region.

Cannabinoid receptor 1 gene polymorphisms and nonalcoholic Fatty liver disease in women with polycystic ovary syndrome and in healthy controls.

Context. Polycystic ovary syndrome (PCOS) is frequently associated with nonalcoholic fatty liver disease (NAFLD). The endocannabinoid system may play a crucial role in the pathogenesis of NAFLD.

Selected CNR1 polymorphisms and hyperandrogenemia as well as fat mass and fat distribution in women with polycystic ovary syndrome.

The endocannabinoid system is postulated to play an important role in the etiology of obesity, insulin resistance, fat distribution and metabolic disorders. Insulin resistance associated with abdominal obesity plays a leading role in the etiology of hyperandrogenism and other clinical features of the polycystic ovary syndrome (PCOS). A total of 174 women 16-38 years old, diagnosed with PCOS according to the Rotterdam criteria are recruited.

The influence of endocannabinoid receptor 1 gene variations on anthropometric and metabolic parameters of women with polycystic ovary syndrome.

Introduction: Polycystic ovary syndrome (PCOS) is associated with an increasing number of metabolic comorbidities. About 50% of PCOS patients are obese, and insulin resistance affects up to 70% of these women. The endocannabinoid system contributes to human energy homeostasis.

Interrelation between genotypes of the vitamin D receptor gene and serum sex hormone concentrations in the Polish elderly population: the PolSenior study.

Aim: Vitamin D co-regulates the synthesis of sex hormones. Therefore, the aim of this study was to determine whether the presence of certain genotypes of the vitamin D receptor gene (VDR) is associated with the serum levels of sex hormones in the elderly Polish population.

Materials And Methods: The rs10735810, rs1544410, rs7975232, and rs731236 polymorphisms of VDR, the serum levels of testosterone and estradiol, as well as free estrogen index (FEI) and free androgen index (FAI) were evaluated in 360 women and 400 men aged 65-90years selected from 5695 respondents of the PolSenior survey.

Telomere length in elderly Caucasians weakly correlates with blood cell counts.

Background: Age-related decrease in bone marrow erythropoietic capacity is often accompanied by the telomere length shortening in peripheral white blood cells. However, limited and conflicting data hamper the conclusive opinion regarding this relationship. Therefore, the aim of this study was to assess an association between telomere length and peripheral blood cell count parameters in the Polish elderly population.

Metformin for polycystic ovary syndrome.

The latest list of reimbursed medicines includes, as a new addition, metformin for the treatment of polycystic ovary syndrome (PCOS), which is extremely important for practicing physicians. While this paper briefly summarises the current state of knowledge on PCOS, its main aim is to remind the reader about the effectiveness of metformin in women with PCOS in controlling glycaemia, increasing tissue sensitivity to insulin and affecting endothelial function, vascular inflammation, lipid profile and other risk factors of atherosclerosis, which suggests its cardioprotective effects. The paper also discusses the clinical effect of metformin relative to hyperandrogenism, menstrual cycle disorders and ovulation induction.

Practical guidelines for the supplementation of vitamin D and the treatment of deficits in Central Europe - recommended vitamin D intakes in the general population and groups at risk of vitamin D deficiency.

Introduction: Adequate Vitamin D intake and its concentration in serum are important for bone health and calcium-phosphate metabolism as well as for optimal function of many organs and tissues. Documented trends in lifestyle, nutritional habits and physical activity appear to be associated with moderate or severe Vitamin D deficits resulting in health problems. Most epidemiological studies suggest that Vitamin D deficiency is prevalent among Central European populations.

Effects of radioiodine administration on serum concentrations of matrix metalloproteinases, adiponectin and thrombospondin-1.

Background: In order to assess safety of radioactive iodine administration in the treatment of thyrotoxicosis, we measured concentrations of matrix metalloproteinase-2 (MMP-2), its main inhibitor - TIMP-2 (tissue inhibitor of MMP-2), matrix metalloproteinase-9 (MMP-9), its main inhibitor - TIMP-1, adiponectin, as well as pro-inflammatory and procancerogenic thrombospondin-1 (TSP-1).

Design And Patients: The study involved 23 patients treated with radioiodine for thyrotoxicosis. Serum concentrations of TSH, free T4, free T3, MMP-2, MMP-9, TIMP-1, TIMP-2, total adiponectin and TSP-1 were measured by immunoassays just before radioiodine administration (visit 1), and subsequently, after 7 days (visit 2), 3 months (visit 3), 6 to 8 months (visit 4) and 15-18 months after radioiodine administration (visit 5).

The reference values of sex hormones and SHBG serum levels in subjects over 65 years old - The PolSenior Study.

Introduction: Over the last decade, average life expectancy has continuously increased. There has been no data on normal sex hormone (SH) levels in a Polish elderly population. In this study, we assessed SH in the PolSenior cohort to determine normal reference ranges in relation to gender, age, and cardiovascular disease risk factors (CVDRFs).

Recommendations of the Polish Society of Endocrinology and Polish Diabetes Association for the management of thyroid dysfunction in type 1 and type 2 diabetes.

Thyroid disorders are more frequently observed in diabetic patients. These conditions have been shown to be mainly of autoimmune origin and all of them may lead to hormonal imbalance. Especially strong links exist between autoimmune thyroid diseases (AITD) and type 1 diabetes.

Evaluation of the prevalence of metabolic obesity and normal weight among the Polish population.

Introduction: In the 1980s, the idea evolved that some individuals with normal weight (Metabolically Obese, Normal-Weight), who probably have increased abdominal fat, have metabolic disturbances related to obesity. This observation initiated the concept of the metabolically obese but normal-weight syndrome (MONW). Since then, there have been only a few studies in non-obese subjects.
