Biological behavior of ovarian carcinomas might be the result of cellular diversity existing in tumor tissue, which consists of differentiated and undifferentiated cells showing stem cells biological properties and function. We examined correlation between p53 protein phosphorylated at serine 20 (p-p53(Ser20)) and CD133, SOX2, Notch1 expression, in order to reveal p-p53(Ser20) stemness function in ovarian cancer. p-p53(Ser20), CD133, Notch1, SOX2 expression was analyzed on 104 ovarian carcinomas using immunohistochemical staining. The positive correlation between p53 and p-p53(Ser20) (p=0.02), p53 and SOX2 (p=0.02), p-p53(Ser20) and Notch1 (p=0.03), p-p53(Ser20) and CD133 (p=0.01) expression was observed in ovarian carcinomas. The parallel expression of p-p53(Ser20)/CD133, p-p53(Ser20)/Notch1 reflecting co-expression of these proteins in single carcinoma cell, and p-p53(Ser20)/SOX2 expression was associated with advanced stage and p-p53(Ser20)/ Notch1, p53/SOX2, p-p53(Ser20)/SOX2 parallel expression correlated with high tumor grade. The correlation between p-p53(Ser20) and CD133, Notch1, SOX2 expression and clinical parameters indicate, that malignancy and biological behavior of ovarian carcinomas depend on interaction between p-p53(Ser20) and carcinoma stem cells biomarkers expression.

Food allergy and eczema are the earliest allergic phenotypes in childhood. These diseases could be related to either IgE-mediated or non-IgE-mediated reactions to the allergen. TNFRSF17 is a key molecule in B cell maturation and is important in both types of responses.We conducted a study comparing the relative expression and the methylation status at the TNFRSF17 in regard to the child's early atopic sensitisation and allergic phenotypes.In the recruited population of 200 women and 174 children with available clinical data (physical examination by allergist and antigen-specific IgE measurements), 78 cord blood samples were included in the gene expression analysis (relative gene expression with GAPDH as reference by RT-PCR) and 96 samples with microarray DNA methylation data (whole genome methylation profile Infinium MethylationEPIC).The altered TNFRSF17 methylation pattern in the cord blood at both single cg04453550 and mean methylation at upstream of TNFRSF17 was observed in children who developed food allergy and/or eczema in early childhood. The change in methylation profile was mirrored by the relative expression. The profile of IgE sensitisation to food and/or inhalant allergens was not significantly associated with either methylation or expression of TNFRSF17.In conclusion, methylation at the upstream sites at TNFRSF17 in the cord blood at birth is associated with food allergy and eczema early in childhood., Competing Interests: Declarations.

Background: Although pregnancy is a physiological process it causes hormonal changes that can also affect the oral cavity. Pregnancy increases the risk of gum disease inflammation and tooth caries which could affect the health of the developing baby. Proper oral health is crucial both for mother and her babies and is related with mothers' awareness of this connection. The aim of this study was the self-assessment of women's both oral health and oral health literacy as well as mothers' awareness of the connection of oral health and pregnancy., Material and Methods: In the study anonymous questionnaire was prepared and provided to be filled in by 200 mothers at the age from 19 to 44 y.o. who gave birth in the gynecological clinic. The questionnaire included demographic, and concerning the areas of oral health before and during pregnancy and after the childbirth questions., Results: Only 20% of the investigated women underwent the oral examination before the pregnancy and the next 38.5% underwent it intentionally when the pregnancy had been confirmed. As much as 24% of women pointed out lack of awareness of the importance of proper oral hygiene during pregnancy. 41.5% of investigated women declared complaints during the pregnancy concerning teeth or gums and 30.5% underwent dental treatment; 68%, brushed their teeth properly-twice a day; 32% of women observed deterioration of oral health state during the pregnancy. The knowledge of the importance of oral health during pregnancy presented by the majority of mothers was relatively proper, which was strongly connected with higher education status and living in big cities. A significant correlation between higher birth weight and more frequent daily tooth brushing was observed. Both higher frequency of problems concerning the oral cavity and dental treatment during pregnancy were significantly related to the younger age of mothers., Conclusions: The knowledge of women concerning of oral health on the management of pregnancy and development of fetus is still insufficient. Gynecologists should inquire pregnant women if they have done dental examination, and provide wider education about importance of oral health in pregnancy., (© 2023. The Author(s).)

This study presents current recommendations of the Polish Association of Pediatric Surgeons (PTChD) regarding diagnostics and treatment of ovarian lesions in girls. They are based on many years of the authors' clinical experience as well as a review of international literature and include practical clinical guidelines. The recommendations were formulated in cooperation with the Polish Association of Pediatric Oncology and Hematology (PTOHD), Polish Pediatric and Adolescent Gynecology Section of the Polish Society of Gynecologists and Obstetricians (PTG) and Polish Pediatric Section of the Polish Society of Radiology (PLTR). Only better understanding of prepubertal ovarian biology and natural history of its pathology may help to introduce efficient and safe diagnostic and therapeutic strategies for girls. The prepared document has been supplemented with treatment algorithms.

Having pets in the house during the first years of life has been shown to protect against allergies. However, the result of different studies is heterogeneous. The aim of this study was to evaluate the methylation pattern in cord blood in relation to pet ownership during pregnancy.We investigated the methylation patterns of 96 cord blood samples, participants of the Epigenetic Hallmark of Maternal Atopy and Diet-ELMA project, born to mothers who either owned pets (n = 32) or did not own pets (n = 64) during their pregnancy. DNA from cord blood was analysed using the Infinium methylation EPIC. For statistical analysis, RnBeads software was applied.We found 113 differentially methylated sites (DMs) in the covariate-adjusted analysis (FDR p < 0.05), with small methylation differences. The top DMs were associated with genes: UBA7, THRAP3, GTDC1, PDE8A and SBK2. In the regional analysis, two promoter regions presented with significance: RN7SL621P and RNU6-211P. Cis-regulatory element analysis revealed significant associations with several immune-related pathways, such as regulation of IL18, Toll signalling, IL6 and complement.We conclude that pet exposure during pregnancy causes subtle but significant changes in methylation patterns in cord blood, which are reflected in the biological processes governing both innate and adaptive immune responses., (© 2021.

Uterine fibroids are the most common mesenchymal uterine neoplasms; their prevalence is estimated in 40%-60% of women under 35 and in 70%-80% of women over 50 years of age. The current research aims to focus on the etiopathogenesis of uterine fibroids, the factors that affect their growth, and markers with diagnostic and prognostic properties. The MCM (minichromosome maintenance) protein family consists of peptides whose primary function is participation in the molecular mechanism of creating replication forks while regulating DNA synthesis. The aim of this work was to determine the proliferative potential of uterine fibroid cells based on the expression of the Ki-67 antigen and the MCMs-i.e., MCM-3, MCM-5, and MCM-7. In addition, the expression of estrogen (ER) and progesterone (PgR) receptors was evaluated and correlated with the expression of the abovementioned observations. Ultimately, received results were analyzed in terms of clinical and pathological data., Materials and Methods: In forty-four cases of uterine fibroids, immunohistochemical reactions were performed. A tissue microarray (TMA) technique was utilized and analyzed cases were assessed in triplicate. Immunohistochemistry was performed using antibodies against Ki-67 antigen, ER, PgR, MCM-3, MCM-5, and MCM-8 on an automated staining platform. Reactions were digitalized by a histologic scanner and quantified utilizing dedicated software for nuclear analysis. Assessment was based on quantification expression of the three histiospots, each representing one case in TMA., Results: In the study group (uterine fibroids), statistically significant stronger expression of all the investigated MCMs was observed, as compared to the control group. In addition, moderate and strong positive correlations were found between all tested proliferative markers. The expression of the MCM-7 protein also correlated positively with ER and PgR. With regard to clinical and pathological data, there was a negative correlation between the expression of MCMs and the number of both pregnancies and births. Significant reductions in MCM-5 and MCM-7 expression were observed in the group of women receiving oral hormonal contraceptives, while smoking women showed an increase in MCM-7, ER, and PgR., Conclusions: Uterine fibroid cells have greater proliferative potential, as evaluated by expression of the Ki-67 antigen and MCMs, than unaltered myometrial cells of the uterine corpus. The expression of MCM-7 was found to have strong or moderate correlations in all assessed relations. In the context of the clinical data, as well evident proliferative potential of MCMs, further studies are strongly recommended.

The increase in the prevalence of allergic diseases is believed to partially depend on environmental changes. DNA methylation is a major epigenetic mechanism, which is known to respond to environmental factors. A number of studies have revealed that patterns of DNA methylation may potentially predict allergic diseases.Here, we examined how maternal atopy is associated with methylation patterns in the cord blood of neonates.We conducted an epigenome-wide association study in a cohort of 96 mother-child pairs. Pregnant women aged not more than 35 years old, not currently smoking or exposed to environmental tobacco smoke, who did not report obesity before conception were considered eligible. They were further tested for atopy. Converted DNA from cord blood was analysed using Infinium MethylationEPIC; for statistical analysis, RnBeads software was applied. Gestational age and sex were included as covariates in the final analysis.83 DM sites were associated with maternal atopy. Within the top DM sites, there were CpG sites which mapped to genes SCD, ITM2C, NT5C3A and NPEPL1. Regional analysis revealed 25 tiling regions, 4 genes, 3 CpG islands and 5 gene promoters, (including PIGCP1, ADAM3A, ZSCAN12P1) associated with maternal atopy. Gene content analysis revealed pointwise enrichments in pathways related to purine-containing compound metabolism, the G1/S transition of the mitotic cell cycle, stem cell division and cellular glucose homoeostasis.These findings suggest that maternal atopy provides a unique intrauterine environment that may constitute the first environment in which exposure is associated with methylation patterns in newborn.

Background: Worldwide, allergy affects more than one billion people, with particularly rising prevalence in industrialised areas. Specifically, young adults appear to be predominantly targeted for an allergy diagnosis. Allergic diseases in pregnancy are mainly pre-existing but could also occur de novo. The immunological changes while pregnant, with increased Th2 lymphocyte activity, can facilitate allergen sensitisation., Objective: The aim of this study was to evaluate the pattern of specific IgE (sIgE) sensitisation to common inhalant and food allergens in pregnancy, and assess its relationship to self-reported allergic disease., Methods: We assessed 200 pregnant women, aged 20-38 years (mean age = 29 years), participant of ELMA (Epigenetic Hallmark of Maternal Atopy and Diet) study, living in a metropolitan area, with no pregnancy associated metabolic complications, for total IgE and allergen specific IgE to 20 allergens., Results: 48% of pregnant women were sensitised to at least one allergen, at a cut-off point of 0.35 kU/L and they were assigned as atopic. However 42% in atopic group were not reporting any allergic disease. The most common inhalant allergens were: pollen (24.5%) and animal dander (23.5%). The most common food allergens were: cow's milk (5.5%) and apples (4.5%). 7.5% of women reported asthma, 21.5% allergic rhinitis, 11.5% atopic dermatitis and 18.5% food allergy. 8.5% of were taking medication for asthma or allergies. Atopic dermatitis had the highest tendency to become more severe during pregnancy. Total IgE values were significantly higher in atopic women., Conclusions: Allergic sensitisation is a common phenomenon in pregnancy. Some sensitisations could be asymptomatic. Further studies should investigate if sensitisation in mothers confers risks for immune alterations in their children.

Background: The activity of autogenic proteolytic enzymes is regulated in vivo by autogenic inhibitors. They play important roles in maintaining a balance in many processes in the human body. In pathological conditions, enzymes are overexpressed and the balance is disturbed. Such uncontrolled changes may lead to the development of local or systemic cancer., Objectives: To evaluate the effects of specific inhibitors, i.e., chicken egg white cystatin (CEWC) and proteinase inhibitor (E-64) on autogenic cysteine peptidases (CPs) in the sera of patients reporting for subsequent stages of treatment after being diagnosed with breast cancer. Cysteine peptidases play a vital role in the basic processes that are associated with cancer progression., Material and Methods: We selected serum samples from 108 patients with a diagnosis of breast cancer (stages IIA-IIIA) who had received no previous treatment. The blood samples were centrifuged, and the resulting serum was placed in liquid nitrogen and stored at -80°C. The biochemical tests were performed at the laboratory of the Department of Physical Chemistry and Microbiology., Results: For CEWC, we found an inhibitory effect in 37 out of 108 samples; for E-64, 14 out of 22 samples displayed an inhibitory effect. In the remaining blood samples, these inhibitors caused an increase in fluorescence. In a parallel test, we added pure cathepsin B to 9 serum samples, and then used CEWC to inhibit the activity of autogenic CPs. Chicken egg white cystatin completely inhibited the cathepsin B that was added to the serum without changing its effect on the autogenic CPs., Conclusions: The results suggest that there may be a potential difference between the commercially available cathepsin B and its autogenic analogues found in the serum of cancer patients. The increase in fluorescence induced in the reaction between the inhibitors and autogenic CPs is still unexplained. There was no relationship between the observed inhibition/activation of CPs and any of the available indicators of the health of the patients examined.

The Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome, also known as Müllerian agenesis or aplasia, is a congenital disease manifested by the aplasia of the uterus and the upper 2/3 of the vagina; its incidence is 1 in 4,000-5,000 female live births. We can distinguish 2 types of the MRKH syndrome: type I, which is characterized by an isolated absence of 2/3 of the vagina and uterus; and type II or MURCS (Müllerian duct aplasia, unilateral renal agenesis and cervicothoracic somite anomalies), which is also associated with other symptoms. The treatment of the MRKH syndrome patients aims at creating a neovagina and enabling sexual intercourse. Non-surgical techniques are the first-choice methods, and more than 90% of patients notice an anatomical and functional improvement if they are well-prepared emotionally. If non-surgical treatment does not bring about the expected results, a surgical procedure remains an option. The surgical method is mainly determined by the surgeon's experience. There are a few types of operations, though none of them seems superior to others. The next challenge is to provide these patients with a chance to become parents. Nowadays, a uterine transplant, a surrogate or adoption are the available solutions. An interdisciplinary approach is required, and the treatment should consist of medical and psychological support. This review presents the current knowledge about the MRKH syndrome with regard to the current methods of non-surgical and surgical treatment as well as a summary of the associated psychological problems.

Background: The key role in carcinogenesis with destruction of the extracellular matrix is played by proteases released by invasive cancer cells. Cysteine peptidases, such as cathepsin B and L, take an important role in cancer progression and metastasis., Objectives: Cysteine peptidase-like activity (CPA) in sera of patients with breast cancer at different stages of disease and the influence of genetic predisposition associated with BRCA-1 gene mutations were analysed., Methods: CPA in serum was determined with the spectrofluorometric technique using Z-Phe-Arg-AMC as a substrate. Determination was carried out in 111 breast cancer patients in comparison to a control group of 50 healthy subjects., Results: The highest CPA was found in breast cancer patients with a hereditary predisposition bearing BRCA1 gene mutations, and the lowest activity was found in patients who had a tumour surgically removed and before adjuvant therapy. The differences in the activities between control group and cancer groups were statistically significant (p< 0.05), except from group of cancer patients in complete remission (p< 0.52)., Conclusions: Serum CPA in patients with breast cancer differs depending on the cancer stage and treatment methods. Our study demonstrate the correlation between BRCA-1 gene mutations and the increased level of CPA.

Background: Remote pregnancy monitoring is one of the most promising applications of telemedicine; however, the diagnostic value of self-examination using mobile cardiotocography (CTG) devices and remote analysis of the subsequent results has never been properly studied., Objectives: The study aimed to compare the diagnostic usefulness of CTG self-examination using a mobile device to examination performed by a medical professional using a stationary device; and to evaluate the quality of CTG analysis performed remotely., Material and Methods: Eighty-two pairs of CTG recordings were collected; each pair consisted of a single recording from an examination performed by a midwife using a stationary device, and another recording from an unassisted patient self-examination using a mobile device. Recordings were performed with a maximum time interval of 30 min. Each recording was analyzed twice. Primary analysis included a comparison of the assisted examination evaluated on-site vs the self-examination evaluated remotely in pairs. Secondary analysis was conducted by an independent expert who evaluated the unpaired recordings. Baseline fetal heart rate (BFHR) values were compared independently., Results: We found that patients were more likely to perform inconclusive recordings than experienced midwives; however, the self-examination feasibility was satisfactory. The primary analysis showed 88.4% agreement of the recorded pairs; 11.6% of inconsistent pairs were due to inter-observer variability or medical reasons. The independent expert's analysis showed 97.1% agreement between the assisted and unassisted examinations. Paired t-test for BFHR values showed a statistically significant but clinically negligible mean difference between the 2 devices at 1.75 bpm., Conclusions: The CTG examinations performed using mobile devices present satisfactory feasibility and equivalent diagnostic value compared to conventional devices, while the remote evaluation of recordings is as reliable as on-site analysis. Remote pregnancy surveillance is safe, effective and may be implemented into everyday obstetric care.

Uterine leiomyomas (LMs), currently the most common gynecological complaint around the world, are a serious medical, social and economic problem. Accurate diagnosis is the necessary prerequisite of the diagnostic-therapeutic process. Statistically, mistakes may occur more often in case of disease entities with high prevalence rates. Histopathology, based on increasingly advanced immunohistochemistry methods, is routinely used in the diagnosis of neoplastic diseases. Markers of the highest sensitivity and specificity profiles are used in the process. As far as LMs are concerned, the crux of the matter is to identify patients with seemingly benign lesions which turn out to be suspicious (e.g., atypical LM) or malignant (e.g., leiomyosarcoma (LMS)), which is not uncommon. In this study, we present the current state of knowledge about the use of immunohistochemical markers in the differential diagnosis of LM, atypical LM, smooth muscle tumors of uncertain malignant potential (STUMP), and LMS, as well as their clinical predictive value.

Objectives: The aim of the study was to determine if adolescents with juvenile bleeding had polycystic ovarian syndrome (PCOS) and insulin resistance., Material and Methods: The study was conducted in a group of 43 females aged 12-18 years, diagnosed with juvenile menorrhagia, and 37 healthy female adolescents aged 12-18 years. The study was conducted during the early follicular phase of the menstrual cycle. Menstrual cycle disturbances, acne and hirsutism were recorded. Ultrasound scan determining the condition of the ovaries was conducted. Laboratory tests of the glucose level, cholesterol, LDL and HDL cholesterol and triglycerides fraction, DHEAS, FSH, LH, insulin, SHGB, total testosterone, androstenedione, and free testosterone have been established., Results: The occurrence of regular menstrual cycles (30.23%, p = 0.006) was significantly lower in the juvenile bleeding group. Also, secondary amenorrhea was significantly more likely to be recognized in this group of females (p = 0.03). The concentration of FSH was considerably lower (p = 0.0002) in the group of adolescents with AUB., Conclusions: Adolescents with abnormal uterine bleeding (AUB) are often diagnosed with secondary amenorrhea, and PCOS. The group with a diagnosis of juvenile bleeding was also diagnosed with higher rates of insulin resistance.

Human microbiome contains the genetic pool of bacteria and other microbes such as Achaea, fungi and viruses inhabiting the human body. It holds an immense potential to affect both physiological and pathological processes. The microbiome's composition can be defined in detail by analyzing ribosomal 16S rRNA and metagenomic tests. Recent increases in cesar- ean sections, the use of antibiotics during pregnancy, the increasing amount of prematurely born children and changes in infant nutrition have an impact on the microbiome forming process. A correlation between the bowel microbiome's com- position and the occurrence of certain diseases, especially inflammatory bowel diseases (IBD), asthma and type 1 diabetes has been demonstrated. The influence on the development of cognitive functions and behaviour has also been displayed. This correlation justifies attempts to restore the beneficial the composition of the microbiome through the use of probiotics, vaginal microflora transfer in case of cesarean section and encouraging breastfeeding. Development of multiple studies on the topic of the human microbiome and its impact on the human body is necessary in order to reach final conclusions. The aim of this article is to summarize recent findings regarding the development of the human microbiome from the first days of life and the influence of changes in its composition on human health.

Pregnant women are at greater risk to suffer from chronic pruritus, but data on this symptom in this group is very limited. The aim of this study was to investigate the prevalence, clinical characteristics, and the importance of pruritus in pregnant women. A total of 292 consecutive pregnant women at the 33.0 ± 6.1 weeks of gestation (WoG) were recruited into this prospective, cross-sectional study. All patients underwent thorough anamnesis and detailed physical examination with the special emphasis on pruritus. Pruritus was assessed according to Visual Analogue Scale (VAS). Quality of life was measured with the Dermatology Life Quality Index (DLQI). The point prevalence of pruritus was 20.2% ( n = 59), while pruritus prevalence during the entire pregnancy was 38.0% ( n = 111). Pruritus started on average at the 27.2 ± 7.6 WoG; it was significantly more common among women in third trimester. The mean VAS was 4.8 (±2.4) points. The DLQI scoring significantly correlated with VAS ( r = 0.52, p < 0.001). Based on the results of our study about one-third of women suffer from pruritus during pregnancy. Many of them find it a very distressing and disturbing symptom.

Metabolic profiles of amniotic fluid and maternal blood are sources of valuable information about fetus development and can be potentially useful in diagnosis of pregnancy disorders. In this study, we applied 1H NMR-based metabolic profiling to track metabolic changes occurring in amniotic fluid (AF) and plasma (PL) of healthy mothers over the course of pregnancy. AF and PL samples were collected in the 2nd (T2) and 3rd (T3) trimester, prolonged pregnancy (PP) until time of delivery (TD). A multivariate data analysis of both biofluids reviled a metabolic switch-like transition between 2nd and 3rd trimester, which was followed by metabolic stabilization throughout the rest of pregnancy probably reflecting the stabilization of fetal maturation and development. The differences were further tested using univariate statistics at α = 0.001. In plasma the progression from T2 to T3 was related to increasing levels of glycerol, choline and ketone bodies (3-hydroxybutyrate and acetoacetate) while pyruvate concentration was significantly decreased. In amniotic fluid, T2 to T3 transition was associated with decreasing levels of glucose, carnitine, amino acids (valine, leucine, isoleucine, alanine, methionine, tyrosine, and phenylalanine) and increasing levels of creatinine, succinate, pyruvate, choline, N,N-dimethylglycine and urocanate. Lactate to pyruvate ratio was decreased in AF and conversely increased in PL. The results of our study, show that metabolomics profiling can be used to better understand physiological changes of the complex interdependencies of the mother, the placenta and the fetus during pregnancy. In the future, these results might be a useful reference point for analysis of complicated pregnancies.

Introduction: Child sexual abuse (CSA) is generally defined as child exploitation that leads to achievement of sexual satisfaction. According to data from European countries, sexual abuse of children affects 10-40% of girls and 5-20% of boys., Material and Methods: The Medline, and Web of Science databases were searched with no date limitation on May 2015 using the terms 'child abuse' in conjunction with 'urinary tract', 'urologist', 'urological dysfunction', 'urologic symptoms', 'LUTS' or 'urinary infection'., Results: Awareness of the CSA problem among paediatricians and urologists is very important, because they are often the only physicians who are able to recognize the problem. CSA diagnosis is possible only through the proper collection of a medical history and a thorough physical examination. Urologists have to remember that children exposed to sexual abuse rarely exhibit abnormal genital findings. In fact, absence of genital findings is the rule rather than the exception. In most cases, the final diagnosis of sexual abuse is based on the child's history and behavior, along with the onset and exacerbation of urologic symptoms., Conclusions: In this article, we present a review of studies and literature concerning urinary symptoms in sexually abused children to clarify the problem for a broad group of urologists. We present common symptoms and premises that can point to the right diagnosis and basic guidelines of proceeding after suspicion of abuse.

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. Thus, higher levels of Gpc4 released from visceral adipose tissue in women with PCOS may suggest an increased risk of cardiovascular disease (CVD)., Design: The aim of this pilot study was to determine whether the serum Gpc4 level is associated with cardiovascular risk predictors in women with PCOS., Methods: Sixty-two women with PCOS according to the Rotterdam criteria (20-35 years old) and 43 healthy controls were studied. Cardiovascular risk predictors such as obesity indices, fat deposits according to dual-energy X-ray absorptiometry, biochemical lipid profile parameters and Homeostasis Model Assessment were estimated., Results: The serum Gpc4 level in PCOS women was significantly higher (2.61 ± 1.17 ng/ml) than in the control group (1.55 ± 0.47 ng/ml) and correlated with waist circumference, waist-to-hip ratio, total fat and android fat deposit to gynoid fat deposit ratio only in the PCOS group., Conclusion: The Gpc4 level was higher in the PCOS group and correlated with CVD risk predictors, especially fat distribution.

Recently, occurrence of urinary tract endometriosis (UTE) is more frequently diagnosed. According to literature, it refers to approximately 0.3 to even 12% of all women with endometriosis. The pathogenesis of UTE has not been clearly explained so far. The actually proposed hypotheses include embryonic, migration, transplantation, and iatrogenic theory. Most frequently UTE affects bladder, less often ureters and kidneys. One-third of patients remains asymptomatic or exhibits only minor manifestations. In symptomatic patients main complaints include dysuria, urinary urgency, and/or frequency, painful micturition, and burning sensation in the urethra and discomfort in the retropubic area. Treatment of UTE is challenging and can be pharmacological, surgical or can be a combination of both methods. In this paper we present a review of the literature concerning the UTE, its diagnosis and treatment.

Background: Human milk provides a multitude of glycoproteins, including highly glycosylated α-1-acid glycoprotein (AGP), which elicits anti-inflammatory and immunomodulatory properties. The milk AGP glycoforms may provide the breastfed infant with a wide range of biological benefits. Here, we analyzed the reactivity of O-linked sugar-specific lectins with human milk AGP over the process of lactation and compared the results with those of the lactating mother's plasma., Materials and Methods: Relative amounts of human skim milk AGP O-glycans were analyzed in early colostrum, colostrum, and transitional and mature milk samples of 127 healthy mothers by lectin-AGP enzyme-linked immunosorbent assay using sialyl T (sialyl-α2,3/α2,6 Galβ1,3GalNAc-), asialyl T (Galβ1,3GalNAc-), and Tn (GalNAc-) antigen-specific biotinylated Artocarpus integrifolia (Jacalin), Arachis hypogaea (PNA), and Vicia villosa (VVA) lectins, respectively., Results: Milk AGP elicited high expression of Jacalin- and PNA-reactive glycotopes and low expression of VVA-reactive glycotopes, which were absent on plasma AGP of lactating mothers and healthy individuals. The expression of sialyl, asialyl T, and Tn glycotopes of human milk AGP was lactation stage related. The relative amount of Jacalin-reactive AGP glycotope was highest in the colostrum samples and then decreased starting from Day 8 of lactation. In contrast, an increase of the relative amount of PNA-reactive glycotope with milk maturation was observed. The relative amount of VVA-reactive glycotope remained almost constant over the development of lactation., Conclusions: Milk AGP differs from mother's plasma AGP by the presence of O-linked sialylated and asialylated T as well as Tn antigens. The variation of the expression of sialylated and asialylated T and Tn antigens on AGP is associated with milk maturation.

Objectives: Fibronectin (FN) is a multifunctional glycoprotein appearing in various glycovariants with potential biological activities. Using lectins we analyzed the expression of terminal glycotopes on human milk fibronectin over lactation and compared it with that of the mother's plasma., Design and Methods: FN concentration and relative amounts of its fucosylated and sialylated glycovariants as well as O-glycans were analyzed in early colostrum, colostrum, transitional and mature milk samples of 132 healthy mothers by lectin-FN-ELISA using α2,3- and α2,6-sialic acid, α1,2-, α1,3-, and α1,6-fucose, and sialyl-T, asialyl-T and Tn antigen specific biotinylated Maackia amurensis, Sambucus nigra, Ulex europaeus, Tetragonolobus purpureus, Lens culinaris, Artocarpus integrifolia, Arachis hypogaea, and Vicia villosa lectins, respectively., Results: FN concentration was almost unchanged during human milk maturation and was about 150 times lower than in plasma of lactating mothers. Milk FN elicited significantly higher expression of sialylated glycotopes including sialyl-T antigen than plasma FN, and contained fucose-linked glycans, as well as T and Tn antigens absent in plasma FN. With milk maturation the expression of α2,6-sialylated, sialyl-T, α1,6- and α1,2-fucosylated epitopes decreased in transitional milk compared with colostrum, whereas that of asialyl-T antigen increased. The expression levels of α2,3-sialyl- and α1,3-fucosyl-glycotopes and Tn antigen on FN were low and did not change over lactation., Conclusion: The expression of terminal sugars on milk FN is different from that of plasma FN of the lactating mother and is associated with milk maturation. The analysis of degree of milk sialylation and fucosylation should be considered during control of biochemical quality of milk collected in milk banks., (Copyright © 2014 The Canadian Society of Clinical Chemists.

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. Control group consisted of 125 healthy women 18-45 years old. Medical history, physical examination, anthropometric parameters and metabolic parameters were carried out. Six CNR1 gene polymorphisms were diagnosed. We observed a significantly three times higher risk of GG genotype in the polymorphism rs12720071 in women with PCOS versus the control group (p = 0.0344, OR = 3.01). A similar, significant 8-fold higher risk (p = 0.0176, OR = 8.81) was demonstrated for genotype CC polymorphism rs806368 associated with PCOS. We observed a 3.6-fold increased risk of hyperandrogenemia (free androgen index - FAI > 7) in patients with GG genotype in the rs12720071 polymorphism and AA genotype in the polymorphism rs1049353 (OR = 2.7). Our study may indicate a role of the endocannabinoid system in the occurrence of a specific hyperandrogenemia phenotype of PCOS.

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. In all women the waist circumference, android/gynoid fat deposit, parameters of lipid and glucose metabolism, testosterone, free androgen index, sex hormone binding globulin (SHBG) and vitamin D were evaluated. Also, VDR gene polymorphisms rs731236, rs7975232, rs1544410 and rs10735810 were assessed., Results: Serum vitamin D levels in both groups were comparable. Also high, comparable frequencies of hypovitaminosis and vitamin D deficiency in both groups were observed. Women with "classic" PCOS phenotype had statistically significantly higher values of all measured parameters, except serum SHBG and high-density lipoprotein (HDL)-cholesterol, which were lower. The frequency of VDR genotype polymorphism was also comparable in both groups., Conclusions: For the first time, we show that endogenous vitamin D deficiency and VDR polymorphisms are not associated with homogeneous "classic" PCOS phenotype.

Background: Because terminal sugars of α-1-acid glycoprotein (AGP) are reported to be involved in anti-inflammatory and immunomodulatory processes, their expressions might have an influence on the proper function of immune system of newborns. Here, relative amounts of sialylated and fucosylated glycotopes on human milk AGP over normal lactation were investigated., Materials and Methods: AGP concentration and relative amounts of its sialylated and fucosylated glycovariants were analyzed in early colostrum, colostrum, and transitional and mature milk samples of 127 healthy mothers by lectin-AGP enzyme-linked immunosorbent assay using α2,3- and α2,6-sialic acid and α1,2-, α1,3-, and α1,6-fucose specific biotinylated Maackia amurensis, Sambucus nigra, Ulex europaeus, Tetragonolobus purpureus, and Lens culinaris lectins, respectively., Results: AGP concentration in human milk was about 30 times lower than in plasma of lactating mothers and decreased gradually over lactation. Milk AGP showed significantly higher expression of sialylated and fucosylated glycotopes in comparison with those of plasma AGP. Milk AGP glycovariants containing α2,6-sialylated and α1,6- and α1,2-fucosylated glycotopes showed the highest relative amounts in early colostrums. With progression of lactation, the expressions of glycotopes α1,2-fucosylated decreased starting from Day 4 and those of α2,6-sialylated and α1,6-fucosylated from Day 8 of lactation, whereas the level of α2,3-sialyl-glycotope was almost constant over 45 days of lactation. In contrast, the expression of α1,3-linked fucose on AGP was low in colostrums and significantly higher in transitional and mature milk., Conclusions: The relative amounts of sialylated and fucosylated glycovariants of human hindmilk AGP significantly varied between Days 2 and 45 of normal lactation.

HPV infections are currently the most frequent cause of genital infections in the USA. Risk factors are early onset of sexual activity, multiple sexual partners, a history STDs, an early age of first pregnancy and tobacco use. In the past, HPV viruses were thought to be STDs, but it is now known that penetration is not necessary. Skin-to-skin or mucosa-to-mucosa contact is enough to transmit the virus, which presents high tropism for those tissues. The Papillomaviridae family includes over 120 viruses, some of which have high malignant transformation rates. The most common malignancy connected to HPV is uterine cervix cancer and anal canal cancer. The range of morphology of perianal lesions means that a thorough clinical examination is required, including an anoscopy. Therapeutic modalities often seek to eliminate macroscopic changes rather than focus on the cause of the infection, which leads to a high recurrence rate. Externally located changes can be eliminated with patient-applied treatments. Those located in the anal canal and distal end of the rectal ampulla require treatment by a qualified medical provider. Due to the high recurrence rate after standard treatment, special attention has been given to vaccinations. The polyvalent vaccine includes HPV viruses with both low and high malignant transformation risk. This has led to a decrease in the rate of malignancies.

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. Polymorphism of the cannabinoid receptor 1 gene (CNR1) may be responsible for individual susceptibility to obesity and related conditions. Objective. To determine the role of genetic variants of CNR1 in the etiopathology of NAFLD in women with PCOS. Design and Setting. Our department (a tertiary referral center) conducted a cross-sectional, case-controlled study. Subjects. 173 women with PCOS (aged 20-35) and 125 healthy, age- and weight-matched controls were studied. Methods. Hepatic steatosis was assessed by ultrasound evaluation. Single nucleotide polymorphisms of CNR1 (rs806368, rs12720071, rs1049353, rs806381, rs10485170, rs6454674) were genotyped. Results. Frequency of the G allele of rs806381 (P < 0.025) and the GG genotype of rs10485170 (P < 0.03) was significantly higher in women with PCOS and NAFLD than in PCOS women without NAFLD. Frequency of the TT genotype of rs6454674 was higher in PCOS women with NAFLD (not significantly, P = 0.059). In multivariate stepwise regression, allele G of rs806381 was associated with PCOS + NAFLD phenotype. Conclusion. Our preliminary results suggest the potential role of CNR1 polymorphisms in the etiology of NAFLD, especially in PCOS women.

The sugar moiety of IgA is known to provide a link between the innate and adaptive immune systems. Terminally located glycotopes on IgA are potential ligands engaged in the interactions which may modulate the biological activities of IgA. In the present work the expressions of Maackia amurensis (MAA), Sambucus nigra (SNA), Lens culinaris (LCA), Tetragonolobus purpureus (LTA), and Ulex europaeus (UEA) reactive glycotopes on maternal plasma and amniotic IgA were evaluated in relation to the progression of a normal human pregnancy, from the 2nd trimester, throughout the 3rd trimester, perinatal period, post-date pregnancy and delivery, by lectin-IgA-ELISA, using specific biotinylated lectins. The amniotic and maternal plasma IgA concentrations and a degree of SNA and LCA reactivity of maternal plasma IgA were almost unaltered during the normal pregnancy. The amniotic IgA from the 2nd trimester was decorated by MAA-, SNA-reactive and LCA-, LTA-, and UEA-reactive glycotopes. At the turn of the 2nd and 3rd trimesters the expression of MAA-, SNA-, LTA-, and UEA-reactive glycotopes, except for LCA-reactive, increased and remained almost at unaltered levels throughout the perinatal period and delivery. However, in the post-date pregnancy the expression of LCA-, LTA-, and UEA-reactive and SNA-reactive glycotopes were significantly higher. The unique fucosylated and sialylated glycovariants of amniotic IgA associated with the progression of the normal pregnancy may illustrate a general importance of carbohydrate-lectin receptor interactions in the control and modulation of biological events to ensuring homeostasis during pregnancy, protection and well-being of fetus.

In recent years the number of Caesarean sections (C-section) has been rapidly increasing. One of the reasons behind this is the fact that the scope of indications for these operations is still widening. The purpose of this article was to present a comparative analysis of the umbilical cord blood gas content, the state of infants, assessed by the Apgar score, and the course of lactation after elective C-sections or natural childbirth. We found that PO2 in the cord blood after natural delivery was appreciably higher than that after C-section. The neonates delivered in a natural way also had an appreciably better Apgar score compared with those after C-section. Compared to mothers who delivered their babies in a natural way, it takes a longer time for C-sectioned women to commence breastfeeding. We conclude that a lower PO2 level in the umbilical cord blood in women subjected to C-section may stem from breathing disorders in neonates at the time of delivery. The way of ending pregnancy has an apparent influence on adaptive abilities of infants to live outside mother's womb.

Respiratory disorders during pregnancy are connected with its physiology. About half of pregnant women suffer from dyspnea on exertion and some 20 % also from dyspnea at rest. Symptoms may intensify in obese patients. Smoking and respiratory disorders influence the well-being of the fetus. This study evaluates respiratory function in pregnant women as assessed by spirometry. The tests were carried out in 54 pregnant women in the 2nd and 3rd trimester. We found reduced values of vital capacity and expiratory reserve volume in all women, which suggests the existence a restrictive respiratory disorder in physiological pregnancy. Smoking seems to cause obstructive disorders; in smoking patients there was a reduction of the Tiffenau ratio. Participation in birth classes had a positive influence on inspiratory capacity. High BMI before pregnancy, excessive weight gain during pregnancy, or age of becoming pregnant did not appreciably influence spirometry results.

Objective: Terminal-located glycotopes on immunoglobulin G (IgG) are potential ligands engaged in the interactions that may modulate the biological activities of IgG. The expressions of sialic acid and fucose residues on amniotic IgG were evaluated here in relation to the progression of normal human pregnancy., Methods: Sialyl-glycotope and fucosyl-glycotope expressions on maternal plasma and amniotic IgG were determined by lectin-IgG-ELISA., Results: The amniotic and maternal plasma IgG concentrations and a degree of α2,6-sialylation and α1,6-fucosylation of maternal plasma IgG were almost unaltered during the normal pregnancy. The plasma IgG of pregnant and nonpregnant women did not contain α2,3-linked sialic acid and α1,3-linked and α1,2-linked fucoses. In contrast, the amniotic IgG from the second trimester was decorated by α2,3-linked sialic acids, α2,6-linked sialic acids, and α1,6-linked fucose, whereas the α1,3-linked and α1,2-linked fucoses were weakly expressed. During 35-37 weeks of gestation, all the parameters increased significantly, and they remained almost at the same levels throughout 35-42 weeks, including the delivery. However, they were significantly higher in the postdate pregnancy group., Conclusion: The degree of sialylation and fucosylation of amniotic IgG was associated with the progression of normal pregnancy., (© 2012 John Wiley & Sons, Ltd.)

We aimed to analyze possible alternations in the sialylation and fucosylation of α(1)-acid glycoprotein (AGP) in pregnancies complicated by postmature syndrome. The relative amounts of sialyl- and fucosyl-glycotopes on AGP were analyzed in 49 plasma and 49 amniotic fluid samples from postmature and normal pregnancies with gestational ages of 41 to 42 weeks by lectin-ELISA using sialic acid- and fucose-specific biotinylated lectins. The amniotic AGP derived from pregnancies complicated by fetal postmaturity contained higher relative amounts of the exposed innermost α1,6- (p < 0.04) as well as outer α1,2-linked fucoses (p < 0.01) compared with normal pregnancies. These changes were limited to the fucosylation, not sialylation, of amniotic AGP, and did not appear in maternal plasma AGP. The over-fucosylation of amniotic AGP may be considered a biochemical marker to monitor pregnancies and predict postmature syndrome complications in newborns, especially in pregnancies ending after 41 weeks.

Objectives: To analyse modifications in AGP fucosylation in relation to different stages of human pregnancy., Design and Methods: The relative amounts of three fucosyl-glycotopes on AGP were analysed by lectin-ELISA using fucose-specific biotinylated lectins in 169 plasma and 178 amniotic fluid samples from normal pregnancies with gestational ages of 14 to 42 weeks., Results: The plasma AGPs of all the pregnant women and amniotic AGPs from the 2nd trimester lacked fucoses. In contrast, in the 3rd trimester the amniotic AGPs were highly decorated by the innermost alpha1,6-fucose as well as alpha1,2- and alpha1,3-fucoses of the outer arms, reaching the highest expression around the perinatal period. At delivery the relative amounts of the alpha1,3- and alpha1,2-AGP isoforms, but not the alpha1,6 isoform, significantly decreased., Conclusions: The highly fucosylated amniotic AGP isoforms could be implicated in regulatory processes to ensure homeostasis during pregnancy and to protect the fetus. They have the potential of becoming laboratory markers in obstetrics to monitor pregnancy.

Background: The presence of fibronectin fragments has been observed in some inflammatory diseases and is believed to reflect tissue breakdown. In this study, possible fibronectin fragmentation and alterations in its domain and sialyl and fucosyl glycotope expressions were analyzed in amniotic fluids in relation to intrauterine infection., Methods: Samples of amniotic fluid were taken from normal pregnancies and pregnancies (28 and 42 weeks) complicated by intrauterine infection. Fibronectin fragmentation was analyzed by immunoblotting. The expression of cellular, fibrin, C-terminal and EDA fibronectin domains, as well as alpha2,3- and alpha2,6-linked sialic acids, and alpha1,6-, alpha1,3- and alpha1,2-linked fucoses, was determined by ELISA, using domain-specific monoclonal antibodies and specific lectins, respectively., Results: Amniotic fibronectin immunoblots from pregnancies with intrauterine infection revealed three groups of results. In group 1, with the native fibronectin band, and in group 2 with bands of native fibronectin and several fibronectin fragments, only higher alpha1,6-linked fucose expression was observed. In the infection group 3, characterized by profound fragmentation of fibronectin, lower expression of all fibronectin domains analyzed and of alpha1,6-linked sialic acid and alpha1,2-linked fucose was found., Conclusions: Amniotic fibronectin status was found to be associated with pregnancy complicated by intrauterine infection. Such alterations could have a potential diagnostic value in the prevention of or intervention in fetal intrauterine infection.

Background: Alterations in the AGP glycoform pattern are not only disease related, but also can occur during physiological processes such as pregnancy. In this paper, possible changes in human amniotic fluid AGP glycan branching and in the type of sialic acid glycosidic attachment to glycans were analyzed with regard to different stages of human pregnancy., Methods: Crossed-affinity immunoelectrophoresis with concanavalin A was used to study AGP branching and lectin-ELISA with two agglutinins from Maackia amurensis and Sambucus nigra was applied to differentiate alpha2,3 and alpha2,6 type sialic acid attachments., Results: Despite almost unchanged levels of total amniotic fluid AGP during pregnancy, alterations in N-glycan branching and in the expression of sialic acid linkage on AGP were found to be associated with different stages of normal pregnancy. Amniotic fluid AGP glycans derived from third trimester compared with those from the second trimester had a higher percentage of tri- and tetra-antennary sialylated N-glycans. In the second trimester, sialic acid alpha2,6 linkage occurred twice as frequently as alpha2,3 linkage, while during the third trimester alpha2,3 linkage increased and both types of linkage appeared in equal proportion., Conclusions: Branched and alpha2,3-sialylated AGP glycoforms in amniotic fluid could contribute to natural innate fetomaternal defense.

Hydrophilic intravaginal tablets based on methylcellulose and containing lactic acid component with Eudragit E-100 undergo swelling in standard conditions. A high flow-limit of the gel that originates from the tablets as well as its dynamic viscosity should allow for the durable dosage form in the vagina. By choosing a 1:1 ratio of lactic acid to Eudragit E-100, it is possible to obtain tablets disintegrating into a gelform at physiological range of 3.8-4.4. An increase in the amount of lactic acid in the complex in relation to the polymer up to 2:1 and 3:1 ratios results in gels with a lower pH. These gels possess an acid reserve that might be ableto neutralise the excess of alkali present in severe vaginal infections.

Intravaginal tablets based on hydrophilic methylcellulose and containing lactic acid complexed with Eudragit E-100 undergo deformation under standard conditions. The high flow--limit of gel originating from the tablets as well as its dynamic viscosity should enable durability of this dosage form on the vaginal mucosa. By selecting either 1 : 1 or 2 : 1 ratios of lactic acid to Eudragit E-100 it is possible to obtain tablets that disintegrate into a gelform at pH 3.8-4.4, i.e. the pH remains within the physiological range. Increasing the amount of lactic acid in the complex in relation to the polymer to a 4:1 ratio results in gels with a lower pH while possessing an acid reserve that can neutralize the excess of alkali present in severe vaginal infections.

Prematurity is of one of the main causes of neonatal morbidity and mortality. Clinical observations show, that periodontitis in pregnant women can be a direct risk factor for preterm labor, with a greater influence rate compared to other risk factors. The aim of the study was to asses the relationship between periodontal diseases and PLBW in the population of women from the Lower Silesian Region (Poland), and the evaluation of prostaglandin E2 (PGE2), interleukin-1 beta (IL-1 beta) levels in gingival cervicular (GCF) and blood serum in women with PLBW and women giving birth on time as well as secretion of these proinflammatory mediators in whole blood after bacterial lipopolysaccharide stimulation. The study group consisted of 84 women with PLBW (39.2% primiparous), aged 17-41 (mean 27.57). The controls were 44 women (47.7% primiparous) aged 16-38 (mean 26.36) who gave birth on time to a normal birthweight baby. PGE2 and IL-1 beta concentrations in serum and GCF were determined by means of immunoenzymatic method (EIA). In the studied population women over 28 years and exposed to medical risk factors had more frequent PLBW occurrence probability. In primiparous over 28 there is 4 times greater probability of preterm labor, and in case of the severe and generalized periodontitis presence there is 3.9 times higher possibility of PLBW compared to women with healthy periodontium. In all women with PLBW there is a significantly higher PGE2 and IL-1 beta concentration in GCF, and in primiparous also PGE2 level in blood serum, compared to controls.
