Current laboratory practice does not provide specific markers for detecting and assessing the advancement of endometriosis in either plasma or peritoneal fluid. The severity of disease is assessed in stages from I to IV based on the results of laparoscopic inspection. The protein annexin A2 (ANXA2) has been reported to be associated with inflammatory processes.Aim of the Study: The study aimed to investigate and compare ANXA2 protein concentration using the ELISA method in plasma and peritoneal fluid in a group of women with endometriosis compared to controls.Materials and Methods: Biological material was collected during a multicenter, cross-sectional study, which was conducted at eight departments during elective laparoscopy from 53 women with and 40 women without endometriosis. Patients were divided by endometriosis stage and infertility status, and then compared with subgroups. Analysis included the Chi-square test for categorical variables, Mann–Whitney U-test and two-sided Wilcoxon rank-sum test for continuous variables.Results: Women with endometriosis had significantly elevated plasma ANXA2 levels compared to women without endometriosis (mean concentrations 28.69 vs 19.61 ng/L, p=0.01). Differences in peritoneal fluid ANXA2 levels were statistically insignificant (mean concentrations of 23.7 vs 22.97 ng/L, p=0.06). Plasma concentrations in patients with stage III and IV endometriosis were significantly higher compared to controls (mean concentrations of 24.19 vs 19.71 ng/L, p=0.03). No such differences were observed in plasma when comparing stages I–II vs III–IV, and stages I–II vs controls (mean concentrations of 33.82 vs 24.19 ng/L, p=0.72 and 33.82 vs 19.71 ng/L, p=0.12, respectively). Comparison of samples from patients with or without infertility, primary or secondary infertility, endometriosis with or without infertility, and non-endometriosis with or without infertility showed no significant differences in the plasma nor in the peritoneal fluid concentrations.Conclusion: ANXA2 is possibly involved in the pathogenesis of endometriosis, especially in advanced stages. Due to the limited group of tested samples, further studies are needed to confirm its role.Keywords: annexin A2, endometriosis, infertility

Endometriosis occurs in 2–4% of postmenopausal women. There have been a few reports of endometriosis in women in whom neither history nor diagnostic imaging indicated the presence of this disease, either at reproductive age or after menopause. A case is described of an 84-year-old patient with extensive deep pelvic endometriosis imitating advanced neoplastic process. [ABSTRACT FROM PUBLISHER]

Abstract Background Immunosuppressive therapy protects the transplanted organ but predisposes the recipient to chronic infections and malignancies. Transplant patients are at risk of cervical intraepithelial neoplasia (CIN) and cervical cancer resulting from an impaired immune response in the case of primary infection or of reactivation of a latent infection with human papillomavirus of high oncogenic potential (HR-HPV). Methods The aim of this study was to assess the prevalence of HR-HPV cervical infections and CIN in 60 female kidney graft recipients of reproductive age in comparison to that in healthy controls. Cervical swabs were analyzed for the presence of HR-HPV DNA. HR-HPV-positive women remained under strict observation and were re-examined after 24 months for the presence of transforming HR-HPV infection by testing for HR-HPV E6/E7 mRNA. All the HR-HPV-positive patients were scheduled for further diagnostic tests including exfoliative cytology, colposcopy and cervical biopsy. Results The prevalence of HR-HPV did not differ significantly between the study group and the healthy controls (18% vs 25%, p = 0.37). There was no correlation between HR-HPV presence and the immunosuppresive regimen, underlying disease, graft function or time interval from transplantation. A higher prevalence of HR-HPV was observed in females who had had ≥2 sexual partners in the past. Among HR-HPV-positive patients, two cases of CIN2+ were diagnosed in each group. In the course of follow-up, transforming HR-HPV infections were detected in two kidney recipients and in one healthy female. Histologic examination confirmed another two cases of CIN2+ developing in the cervical canal. Conclusions Female kidney graft recipients of reproductive age are as exposed to HR-HPV infection as are healthy individuals. Tests detecting the presence of HR-HPV E6/E7 mRNA offer a novel diagnostic opportunity in those patients, especially in those cases where lesions have developed in the cervical canal.

Background: Observational studies have shown that fetoscopic endoluminal tracheal occlusion (FETO) has been associated with increased survival among infants with severe pulmonary hypoplasia due to isolated congenital diaphragmatic hernia on the left side, but data from randomized trials are lacking.Methods: In this open-label trial conducted at centers with experience in FETO and other types of prenatal surgery, we randomly assigned, in a 1:1 ratio, women carrying singleton fetuses with severe isolated congenital diaphragmatic hernia on the left side to FETO at 27 to 29 weeks of gestation or expectant care. Both treatments were followed by standardized postnatal care. The primary outcome was infant survival to discharge from the neonatal intensive care unit. We used a group-sequential design with five prespecified interim analyses for superiority, with a maximum sample size of 116 women.Results: The trial was stopped early for efficacy after the third interim analysis. In an intention-to-treat analysis that included 80 women, 40% of infants (16 of 40) in the FETO group survived to discharge, as compared with 15% (6 of 40) in the expectant care group (relative risk, 2.67; 95% confidence interval [CI], 1.22 to 6.11; two-sided P = 0.009). Survival to 6 months of age was identical to the survival to discharge (relative risk, 2.67; 95% CI, 1.22 to 6.11). The incidence of preterm, prelabor rupture of membranes was higher among women in the FETO group than among those in the expectant care group (47% vs. 11%; relative risk, 4.51; 95% CI, 1.83 to 11.9), as was the incidence of preterm birth (75% vs. 29%; relative risk, 2.59; 95% CI, 1.59 to 4.52). One neonatal death occurred after emergency delivery for placental laceration from fetoscopic balloon removal, and one neonatal death occurred because of failed balloon removal. In an analysis that included 11 additional participants with data that were available after the trial was stopped, survival to discharge was 36% among infants in the FETO group and 14% among those in the expectant care group (relative risk, 2.65; 95% CI, 1.21 to 6.09).Conclusions: In fetuses with isolated severe congenital diaphragmatic hernia on the left side, FETO performed at 27 to 29 weeks of gestation resulted in a significant benefit over expectant care with respect to survival to discharge, and this benefit was sustained to 6 months of age. FETO increased the risks of preterm, prelabor rupture of membranes and preterm birth. (Funded by the European Commission and others; TOTAL ClinicalTrials.gov number, NCT01240057.).

Introduction Kidney transplantation (KTx) is the treatment of choice in patients with end-stage renal failure. Among various medical issues in female graft recipients, the need for maternity can become an overriding one. Gonadal dysfunction usually resolves within 6 months after transplantation; however, the prevalence of infertility is similar to this in the general population. Materials and methods This case series describes the experience in infertility treatment and following perinatal care among KTx women who underwent successful in vitro fertilization (IVF). We followed three patients who previously received KTx and underwent IVF between 2014 and 2015. The 34-year-old (patient A) and 39-year-old (patient B) women received single KTx, and the 31-year-old (patient C) woman had received three previous transplantations. Patients A and C were diagnosed with primary tubal factor infertility, while patient B suffered from secondary idiopathic infertility. The stimulation protocols had no influence on their general condition nor graft function. Viable singleton pregnancies were confirmed in all cases. All newborns were born preterm, via cesarean section, as a consequence of severe preeclampsia. Patients A and C gave birth at 34th week of gestation (WG) (A: 1810 g and C: 2295 g), while patient B gave birth at 36th WG (2655 g). Other pregnancy complications were intrauterine growth restriction (patient A) and gestational diabetes mellitus (patient B). Although mild graft dysfunction was observed prior to delivery, all clinical measures and hypertension resolved during the puerperium. Conclusions In these cases, pregnancy after KTx did not implicate persistent graft dysfunction. Regardless of the method of conception, pregnancy following KTx is associated with an increased incidence of complications, therefore it requires a multidisciplinary approach. IVF itself seems to be a safe procedure in KTx recipients if the pregnancy is advisable. [ABSTRACT FROM AUTHOR]

Background Chronic immunosuppression constitutes a risk factor of human papillomavirus (HPV) related cervical cancer development. Maintenance immunosuppression with mammalian target of rapamycin (mTOR) inhibitors is associated with decreased incidence of de novo malignancies in kidney graft recipients. Recently published data suggest that mTOR inhibitors interfere with viral replication. The aim of the study was to assess if there is a difference in prevalence of HPV cervical infection in women on immunosuppressive regimens with or without mTOR inhibitors. Material and Methods Cervical swabs taken from 64 immunosuppressed women on renal replacement therapy were analyzed for the presence of high-risk (HR) HPV DNA by means of an Amplicor HPV test and assessed taking into account the recorded data on mTOR inhibitor use. Results The testing revealed the presence of HR HPV DNA in none of the women that were treated with mTOR inhibitors and in 21.4% of patients that were administered immunosuppressive regimens without mTOR inhibitors ( P = .08). Interestingly, 32% of women from the mTOR(−) group in contrast to 12.5% in the mTOR(+) group declared having had more than 2 lifetime sexual partners. Conclusions Our results suggest that mTOR inhibitors might constitute a promising therapy modification in women at risk of HPV cervical malignancy development, but the effectiveness of such strategy requires further studies.

Objective The aim of this study was to evaluate whether chronic use of immunosuppressive drugs during pregnancy in women after renal transplantation affects the concentration of immunoglobulin G (IgG) and IgM in the serum of their children. Material Seventy-eight children aged 1 day to 15 years were enrolled. The study group consisted of 39 children born to renal transplant recipient mothers. The control group comprised 39 children whose mothers had not received immunosuppressive medications during pregnancy and were born at similar gestational age. Methods Serum concentrations of IgG and IgM were evaluated with the use of agglutination immunoassays on Siemens or Cobas device. Age-adjusted reference values for immunoglobulins formulated by Wolska-Kusnierz et al were used. Statistical analysis was performed with the use of Statistica 10.0 software with P value <.05 considered significant. Results Normal IgG concentrations were found in 82.05% (32) of children from the study group and 79.49% (31) of the control group. IgG concentrations below normal range were observed in 12.82% (5) of children from the study group and in 15.38% (6) of the control group. Normal concentrations of IgM were found in 53.85% (21) of children from the study group and in 61.54% (24) of the control group. Decreased levels of IgM were observed in 38.46% (15) of children from the study group and 35.9% (14) of the control group. There were no significant differences regarding the analyzed values between the groups. Conclusion The exposure to chronic intrauterine immunosuppression had no significant effect on the concentration of IgG or IgM in children born to kidney transplant recipients.

Introduction Immunosuppressive treatment used in pregnant liver recipients may have a negative impact on fetal development and successively a child. Aim The aim of the study was to make a neurological assessment of infants and children born to liver transplant recipients (LTRs) born between December 4, 2001, and February 11, 2013, in the 1 st Department of Obstetrics and Gynecology, Medical University of Warsaw. Methods and Materials The study involved 88 children, of whom 44 children were born to LTR mothers, and 44 children born to women who were not organ recipients and delivered at a similar gestational age. The gestational age of neonates ranged from 33 to 41 weeks, and the birth weight ranged from 1420 g to 4100 g. The neurological examination was performed in children from 7 weeks to 10 years of age. The neurological development was assessed by a specialist in pediatric neurology. The results of the examination were divided according to the following criteria: 1) normal development, 2) slight disorders, 3) moderate disorders, and 4) severe disorders. The Fisher's exact test was used for statistical analysis. Results Normal development was found in 35 of 44 (79.54%) children in the LTR group and 39 of 44 (88.63%) children in the control group ( P = .3827). Slight disorders were observed in 6 of 44 (13.63%) children in LTR group and 5 of 44 (11.36%) children in the control group. Moderate disorders were found only in 3 of 44 (6.81%) children in the LTR group. No severe disorders were observed in both groups. Conclusions Neurological development of children born to the liver recipients who were exposed to chronic immunosuppressive treatment in their fetal lives is the same as that of children whose mothers have not undergone organ transplantation.

Introduction Children of mothers after liver transplantation (LT) are exposed during fetal life to the immunosuppressive agents. These drugs may have hepatotoxic and nephrotoxic effects. Objectives The aim of the work was to assess liver and kidney parameters of children born from mothers who had LT. Materials and Methods The research included 51 children of mothers after LT and 51 children from a control group who were born in the First Department of Obstetrics and Gynecology in Warsaw between 2001 and 2013. The control group consisted of children born in the similar gestational age. Analysis concerned neonates, infants, and children older than 12 months. Two liver parameters (alanine transaminase [ALT] and aspartate transaminase [AST]) as well as two kidney parameters (urea and creatinine) were assessed. For statistical analysis we used Fisher's exact test and the Mann-Whitney test. Results All children from the LT group had correct ALT levels. In the control group, 5 of 51 cases (9.8 %) had levels that were greater than the norm, and those cases concerned only children younger than 12 months. The average concentration of ALT in the LT group was 15.14 U/L and the average for the control group was 22.6 U/L ( P = .012699, Mann-Whitney test). Three of 51 children in the LT group (5.9%) and 8 of 51 (15.7%) in the control group had AST levels that were increased ( P = .2003; Fisher's exact test). Incorrect AST levels were reported in all age groups. Incorrect values of kidney parameters concerned only neonates. Increased creatinine levels were reported in 3 of 51 cases (5.9%) in the LT group and in 1 of 51 cases (1.96%) in the control group ( P = .6175; Fisher's exact test). The average concentration of creatinine in children of mothers after LT was 0.51 mg/dL, and the average of the control group was 0.44 mg/dL ( P = .223698; Mann-Whitney test). Only 1 of 51 children in the LT group (1.96%) had an increased urea level. All children from both the LT and the control groups had normal ultrasound images of urinary tract and liver. Conclusion Exposure to immunosuppressive drugs during fetal life does not result in the occurrence of serious disturbances of liver function and kidneys function in children of mothers after LT.

Background Nowadays pregnancy after organ transplantation is possible due to advances in surgical and immunosuppressive therapies. One of the possible complications in pregnancy after organ transplantation is intrauterine growth restriction (IUGR). This may lead to various adverse perinatal outcomes. Prevalence of IUGR in the general population is estimated at 3%–10% with smoking being the most frequent maternal risk factor. The aim of this study was to determine the risk factors of IUGR in pregnant renal transplant recipients (RTR) or liver transplant recipients (LTR) in comparison with healthy pregnant women. Methods Retrospective analysis included 48 RTR and 52 LTR. IUGR was defined as estimated fetal weight less than the 10th percentile for gestational age. IUGR was diagnosed in 15 (31.3%) pregnant RTR and in 10 (19.2%) LTR. The control group consisted of 60 healthy pregnant women diagnosed with IUGR. Fisher exact test and Student t test were used to assess the differences in fractions and means, respectively, between distinguished groups of patients. Test for fractions based on asymptotic normal distribution was used to compare the proportion of patients with IUGR with the proportion of 10% in the general population. The logistic regression model was used to assess the statistical significance of correlations between the assumed risk factors and the prevalence of IUGR in multivariate settings. Results Hypertension, anemia, and proteinuria were the most frequent complications in the study group. They were more prominent in RTR than in LTR. Hypertension was diagnosed in all RTR, whereas severe anemia requiring erythropoietin treatment or blood transfusion was found in 4 RTR and in 1 LTR. Conclusion IUGR is more common in organ recipients. Therefore, vigilant obstetric care is highly recommended in pregnant patients after renal or liver transplantation. Hypertension, severe anemia, and proteinuria proved not to be statistically significantly correlated with the prevalence of IUGR among patients after transplantation. [ABSTRACT FROM AUTHOR]

Purpose: Endometriosis is a common disease with a complex pathomechanism and atypical symptoms, often leading to delayed diagnosis. Currently, the sole method for confirming the presence of the disease is through laparoscopy and histopathological examination of collected tissue. However, this invasive procedure carries potential risk and complications, necessitating the exploration of non-surgical diagnostic methods for endometriosis. This study aims to analyze peritoneal fluid and plasma samples for the expression of cathepsin L and cathepsin S to identify potential biomarkers for non-invasive diagnostic approaches to endometriosis., Material and Methods: In this cross-sectional study, plasma and peritoneal fluid samples were obtained during laparoscopy from 63 patients diagnosed with chronic pelvic pain or infertility. The study group consisted of women with confirmed endometriosis. The concentrations of cathepsins L and S were determined using an SPRi biosensor., Results: The study did not reveal significant differences in the concentrations of cathepsin L and cathepsin S between the control group and the study group, both in peritoneal fluid and plasma., Conclusions: Based on the results of this study, it appears that cathepsins L and S are not suitable candidates as biomarkers for endometriosis., Competing Interests: Declaration of competing interest The authors declare no conflicts of interests., (Copyright © 2024.

Objective: This study aimed to assess the utility of circulating miR-125b-5p, miR-199a-3p, miR-451a, and miR-3613-5p as biomarkers of endometriosis., Study Design: Patients with stage III or IV of endometriosis according to the revised American Society of Reproductive Medicine (rASRM) staging classification, as well as control women, were recruited. We created a prospective study conducted on a group of 48 patients (n = 25 controls, n = 24 endometriosis) who had laparoscopic surgery. Blood samples were taken and plasma miRNA levels were measured by quantitative real-time polymerase chain reaction (RT-qPCR) and assessed with AUC and ROC curves., Results: MiR-451a and miR-3613-5p were significantly decreased in the plasma of endometriosis patients. miR-451a had a receiver-operating characteristic (ROC) area under the curve 0.8283 and miR-3613-5p had a ROC area under the curve 0.7617. The concentration of circulating miR-125b-5p and miR-199-3p did not differ between endometriosis patients and controls. Plasma miRNA levels did not change with BMI, smoking status, fertility problems, or menstrual pain according to the VAS scale (p > 0.05)., Conclusion: Circulating miR-451a and miR-3613-5p levels significantly differed between endometriosis and controls. However, the levels of miR-451a were discordant with previous studies. Therefore, miR-3613-5p may have better potential as the endometriosis biomarker. Circulating miR-125b-5p and miR-199a-3p cannot be used as reliable markers of endometriosis., Competing Interests: Declaration of Competing Interest All the authors have no interest to declare., (Copyright © 2023 The Authors.

Endometriosis is a chronic disease in which the endometrium cells are located outside the uterine cavity. The aim of this study was to evaluate circulating 20S proteasome and 20S immunoproteasome levels in plasma and peritoneal fluid in women with and without endometriosis in order to assess their usefulness as biomarkers of disease. Concentrations were measured using surface plasmon resonance imaging biosensors. Patients with suspected endometriosis were included in the study-plasma was collected in 112 cases and peritoneal fluid in 75. Based on the presence of endometriosis lesions detected during laparoscopy, patients were divided into a study group (confirmed endometriosis) and a control group (patients without endometriosis). Proteasome and immunoproteasome levels in both the plasma ( p = 0.174; p = 0.696, respectively) and the peritoneal fluid ( p = 0.909; p = 0.284, respectively) did not differ between those groups. There was a statistically significant difference in the plasma proteasome levels between patients in the control group and those with mild (Stage I and II) endometriosis ( p = 0.047) and in the plasma immunoproteasome levels in patients with ovarian cysts compared to those without ( p = 0.017). The results of our study do not support the relevance of proteasome and immunoproteasome determination as biomarkers of the disease but suggest a potentially active role in the pathogenesis of endometriosis.

Respiratory syncytial virus (RSV) is the most common pathogen causing respiratory tract infections in infants, affecting over 90% of children within the first two years of life. It may cause lower respiratory tract infections, which constitute a significant healthcare burden both in the primary and secondary care settings. Meanwhile, the data regarding RSV disease in Poland is scarce, and published data significantly differs from the numbers reported for other countries with longstanding surveillance and reporting systems. A literature review and an expert panel were conducted to (1) understand the healthcare burden of RSV infections in Poland; (2) collect data on infection seasonality, patient pathway, and management patterns; and (3) evaluate RSV infection surveillance in Poland. According to the literature, RSV is the major agent responsible for non-influenza respiratory diseases in Poland. The reported rates of hospitalization for RSV infections are 267.5/100,000 for children under 5 years of age and 1132.1/100,000 for those under 1 year of age. Comparisons with data from other countries suggest that these values may be underestimated, possibly due to insufficient access to microbiological testing and a low awareness of RSV. Infections occur mainly between December and April, however, this pattern has changed following the implementation of preventive measures for coronavirus disease 2019 in the past few years. According to available reports, bronchodilators, antibiotics, corticosteroids, and X-ray imaging have been frequently used. The surveillance system in Poland has limitations, but these may be overcome due to recent changes in healthcare law as well as the availability and reimbursement of diagnostic tests.

Expressional profiling of the endometrium enables the personalised timing of the window of implantation (WOI). This study presents and evaluates a novel analytical pipeline based on a TAC-seq (Targeted Allele Counting by sequencing) method for endometrial dating. The expressional profiles were clustered, and differential expression analysis was performed on the model development group, using 63 endometrial biopsies spanning over proliferative (PE, n = 18), early-secretory (ESE, n = 18), mid-secretory (MSE, n = 17) and late-secretory (LSE, n = 10) endometrial phases of the natural cycle. A quantitative predictor model was trained on the development group and validated on sequenced samples from healthy women, consisting of 52 paired samples taken from ESE and MSE phases and five LSE phase samples from 31 individuals. Finally, the developed test was applied to 44 MSE phase samples from a study group of patients diagnosed with recurrent implantation failure (RIF). In validation samples (n = 57), we detected displaced WOI in 1.8% of the samples from fertile women. In the RIF study group, we detected a significantly higher proportion of the samples with shifted WOI than in the validation set of samples from fertile women, 15.9% and 1.8% (p = 0.012), respectively. The developed model was evaluated with an average cross-validation accuracy of 98.8% and an accuracy of 98.2% in the validation group. The developed beREADY screening model enables sensitive and dynamic detection of selected transcriptome biomarkers, providing a quantitative and accurate prediction of endometrial receptivity status., (© 2023.

An evaluation of the association between the concentrations of vitamin D-binding protein and lactoferrin in the plasma and peritoneal fluid may facilitate the elucidation of molecular mechanisms in endometriosis. Vitamin D-binding protein and lactoferrin concentrations were measured by ELISA in plasma and peritoneal fluid samples from 95 women with suspected endometriosis as classified by laparoscopy into groups with (n = 59) and without endometriosis (n = 36). There were no differences ( p > 0.05) in the plasma and peritoneal fluid concentrations of vitamin D-binding protein and lactoferrin between women with and without endometriosis. In women with endometriosis, there was a significant correlation between plasma and peritoneal fluid vitamin D-binding protein concentrations (r = 0.821; p = 0.000), but there was no correlation between lactoferrin concentrations in those compartments (r = 0.049; p > 0.05). Furthermore, in endometriosis, lactoferrin was found to correlate poorly with vitamin D-binding protein (r= -0.236; p > 0.05) in plasma, while in the peritoneal fluid, the correlation between those proteins was significant (r = 0.399; p = 0.002). The characteristic properties of vitamin D-binding protein and lactoferrin and the associations between their plasma and peritoneal fluid concentrations found in women with endometriosis may provide a novel panel of markers to identify high-risk patients in need of further diagnostic measures.

Introduction: All epidemiological studies suggest that vitamin D deficiency is prevalent among the Polish general population. Since vitamin D deficiency was shown to be among the risk factors for many diseases and for all-cause mortality, concern about this problem led us to update the previous Polish recommendations. Methods: After reviewing the epidemiological evidence, case-control studies and randomized control trials (RCTs), a Polish multidisciplinary group formulated questions on the recommendations for prophylaxis and treatment of vitamin D deficiency both for the general population and for the risk groups of patients. The scientific evidence of pleiotropic effects of vitamin D as well as the results of panelists' voting were reviewed and discussed. Thirty-four authors representing different areas of expertise prepared position statements. The consensus group, representing eight Polish/international medical societies and eight national specialist consultants, prepared the final Polish recommendations. Results: Based on networking discussions, the ranges of total serum 25-hydroxyvitamin D concentration indicating vitamin D deficiency [<20 ng/mL (<50 nmol/L)], suboptimal status [20-30 ng/mL (50-75 nmol/L)], and optimal concentration [30-50 ng/mL (75-125 nmol/L)] were confirmed. Practical guidelines for cholecalciferol (vitamin D 3 ) as the first choice for prophylaxis and treatment of vitamin D deficiency were developed. Calcifediol dosing as the second choice for preventing and treating vitamin D deficiency was introduced. Conclusions: Improving the vitamin D status of the general population and treatment of risk groups of patients must be again announced as healthcare policy to reduce a risk of spectrum of diseases. This paper offers consensus statements on prophylaxis and treatment strategies for vitamin D deficiency in Poland.

The aim of this study was to investigate the relationship between lactoferrin and iron and its binding proteins in women with endometriosis by simultaneously measuring these parameters in plasma and peritoneal fluid. Ninety women were evaluated, of whom 57 were confirmed as having endometriosis. Lactoferrin was measured by ELISA, transferrin, ferritin and iron on a Cobas 8000 analyser. Lactoferrin and transferrin in peritoneal fluid were lower compared to plasma, in contrast to ferritin and iron. In plasma, lactoferrin showeds associations with iron and transferrin in endometriosis and with ferritin in the group without endometriosis. Lactoferrin in peritoneal fluid correlated with lactoferrin, iron and transferrin of plasma in patients without endometriosis. The ratio of lactoferrin concentration in peritoneal fluid to plasma differentiated stage I versus IV of endometriosis and was negatively correlated with the iron ratio in patients without endometriosis. The ferritin ratio differentiated women with and without endometriosis. The very high ferritin ratios, especially in advanced stages of endometriosis, suggest the protective involvement of this protein in peritoneal fluid and the loss of this role by lactoferrin. The results demonstrate the validity of assessing iron metabolism in women with endometriosis, which may be useful as a marker of the disease and its progression.

Hyperglycaemia in pregnancy is one of the most common complications of pregnancy and is generally diagnosed as gestational diabetes mellitus (GDM). Nevertheless, clinical symptoms of hyperglycaemia in pregnancy in some cases do not match the clinical manifestations of GDM. It is suspected that 1-2 % of women diagnosed with GDM are misdiagnosed maturity-onset diabetes of the young (MODY). MODY often has a subclinical course; thus, it is challenging for clinicians to aptly diagnose monogenic diabetes in pregnancy. Proper diagnosis is crucial for the effective treatment of hyperglycaemia in pregnancy. Many studies revealed that misdiagnosis of MODY increases the rate of complications for both mother and fetus. This literature review reports the current knowledge regarding diagnosis, treatment, and complications of the most common types of MODY in pregnancy., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

Laparoscopy as a diagnostic tool for patients with suspected endometriosis is associated with several potentially life-threatening complications. Therefore, it is imperative to identify reliable, non-invasive biomarkers of the disease. The aim of this study was to analyse the concentrations of fibronectin and type IV collagen in peritoneal fluid and plasma to assess their role as potential biomarkers in the diagnosis of endometriosis. Fibronectin and collagen IV protein levels were assessed by surface plasmon resonance imaging (SPRi) biosensors with the usage of monoclonal antibodies. All patients enrolled in the study were referred for laparoscopy for the diagnosis of infertility or chronic pelvic pain (n = 84). The study group included patients with endometriosis confirmed during surgery (n = 49). The concentration of fibronectin in the plasma (329.3 ± 98.5 mg/L) and peritoneal fluid (26.8 ± 11.1 μg/L) in women with endometriosis was significantly higher than in the control group (251.2 ± 84.0 mg/L, 7.0 ± 5.9 μg/L). Fibronectin levels were independent of endometriosis stage ( p = 0.874, p = 0.469). No significant differences were observed in collagen IV levels ( p = 0.385, p = 0.465). The presence of elevated levels of fibronectin may indicate abnormalities in cell-ECM signalling during the course of endometriosis, and may be a potential biomarker for early detection.

The COVID-19 pandemic has burdened the healthcare system and influenced individuals' health-related choices. The aim of the study was to estimate the prevalence and to identify the correlates of the use of more and less effective contraceptive methods among Poles in the initial period of the COVID-19 pandemic. The cross-sectional online study was conducted among the representative sample of 642 female respondents aged 18-49. Three groups of contraception choices (only effective methods-42.2%, mixed effective and ineffective methods-26.8%, none-31.0%) were distinguished and 11 potential determinants were considered. One in ten women declared having difficulty in accessing contraception during the first months of the pandemic. A multinomial logistic regression model explained 48.7% of the variation in contraceptive method choice. Both effective and ineffective methods were more often declared by young women, and less often in case of lower education, planning children or subjective no need for contraception. In addition, factors that reduced the chance of effective contraception were poor financial situation, already having children and a relatively higher degree of religiosity. The study confirmed that a significant share of Polish women do not opt for effective methods of contraception. Their choices had strong demographic, social and cultural determinants.

Purpose: Placenta praevia affects about 0.5% of pregnancies and due to constant increase in operative deliveries may become an important, clinical challenge throughout the next decades. Location of the placental plate within lower uterine segment is associated with increased risk of adverse perinatal outcomes. There were several reports pointing increased risk of small-for-gestational-age (SGA)/fetal growth restriction (FGR) in patients affected with abnormal location of the placenta. On the other hand, some studies ended up with opposite conclusions., Materials and Methods: Due to ambiguous results we have undertaken a case-control study to investigate intrauterine growth among this group. We ran a pilot study to precisely define maternal, obstetrical and neonatal characteristics in order to avoid cofounders. Our study incorporated 56 patients in singleton pregnancies affected with placenta praevia and 124 patients in the control group (between 35 and 37 weeks of gestation)., Results: Nonetheless, there were no statistical differences in the birthweight between the study and control group (2882.5 g vs. 2805 g, p = ns). Moreover, rates of the newborns with birthweight corresponding <10th percentile and >90th did not differ significantly. Even further analysis that included parity did not reveal any differences between both groups., Conclusion: Placenta praevia does not affect the intrauterine growth and shall not be considered as a risk factor for SGA/FGR. In patients affected with abnormal location of the placenta additional scans for fetal well-being assessment are not indicated.

Zinc finger E-box-binding homeobox 1 (ZEB1) and zinc finger E-box-binding homeobox 2 (ZEB2) are transcription factors that regulate epithelial−mesenchymal transformation (EMT). The aim of this study was to compare levels of ZEB1 and ZEB2 in the peritoneal fluid and plasma between patients with and without endometriosis in order to assess their utility in the diagnostic process. Plasma and peritoneal fluid samples were collected from 50 patients with and 48 without endometriosis during planned surgical procedures in eight clinical centers. Quantitative ZEB1 and ZEB2 levels analyses were performed using a double-antibody sandwich enzyme-linked immunosorbent assay (ELISA). No significant differences were observed in ZEB1 levels in any of the subanalyses nor any differences regarding ZEB2 levels between patients with and without endometriosis. Plasma ZEB2 levels were significantly higher among patients with infertility compared to fertile women (16.07 ± 12.70 ng/L vs. 12.07 ± 11.92 ng/L; p < 0.04). Both ZEB1 and ZEB2 do not seem to have a significant value in the initial diagnosis of endometriosis as a single marker. The differences in ZEB2 plasma levels between patients with and without infertility indicate the possibility of EMT dysregulation in the pathogenesis of adverse fertility outcomes.

The evidence of poly (ADP-ribose) polymerase (PARP) association with the immune response could be coherent with the immunological theory of endometriosis and suggests the possibility of a new research direction. The aim of the study was to evaluate the levels of PARP in plasma and peritoneal fluid of patients with and without endometriosis. It was a multicenter, cross-sectional study. Plasma and peritoneal fluid samples were collected from patients with and without endometriosis during planned laparoscopic procedures in eight clinical centers. In total, 84 samples of plasma and 84 samples of the peritoneal fluid were included in the final analyses. Double-antibody sandwich enzyme-linked immunosorbent assay was performed in order to assess levels of PARP in collected samples. No statistically significant differences regarding the detected levels of PARP in plasma and peritoneal fluid comparing patients with and without endometriosis were observed. Patients with a history of infertility had significantly higher plasma PARP concentrations ( p = 0.04). We have not observed the potential role of PARP concentration levels in plasma nor peritoneal fluid as an endometriosis biomarker. We have determined an association between a higher plasma PARP concentration and a history of infertility.

Cadherin 12 (CDH 12) can play a role in the pathogenesis of endometriosis. The aim of this study was to compare the levels of cadherin 12 in the peritoneal fluid between women with and without endometriosis. This was a multicenter cross-sectional study. Eighty-two patients undergoing laparoscopic procedures were enrolled in the study. Cadherin 12 concentrations were determined using the enzyme-linked immunosorbent assay. The level of statistical significance was set at p < 0.05. No differences in cadherin 12 concentrations between patients with and without endometriosis were observed ( p = 0.4). Subgroup analyses showed that CDH 12 concentrations were significantly higher in patients with infertility or primary infertility and endometriosis in comparison with patients without endometriosis and without infertility or primary infertility ( p = 0.02) and also higher in patients with stage I or II endometriosis and infertility or primary infertility than in patients without endometriosis and infertility or primary infertility ( p = 0.03, p = 0.048, respectively). In total, CDH 12 levels were significantly higher in patients diagnosed with infertility or primary infertility ( p = 0.0092, p = 0.009, respectively) than in fertile women. Cadherin 12 can possibly play a role in the pathogenesis of infertility, both in women with and without endometriosis.

Autism spectrum disorders (ASDs) are multifactorial and complex neurodevelopmental conditions usually diagnosed in the early childhood. The etiology of ASDs is commonly described as a genetic predisposition combined with an environmental impact. As a result of broadening of the diagnostic criteria the prevalence of ASDs has been increasing worldwide and the search for the modifiable factors is still on-going. Epidural analgesia (ELA) provides effective pain relief during labor and is currently the most preferred method of anesthesia during the delivery. The safety of the procedure is well-discussed and documented; nonetheless, in 2020 a single population-based study indicated an association between the use of ELA during labor and newborn risk of ASD development, which led to widespread concern. To explore the possible association between the ELA and ASD occurrence in the offspring several studies in different countries have been conducted to date. In this review we aimed to summarize the current state of knowledge concerning the association between the use of epidural analgesia during labor and risk of ASD. In conclusion, the literature review indicates that there is no significant association.

Gestational diabetes mellitus (GDM) is one of the most common complications of pregnancy, affecting up to 14% of pregnant women. The population of patients with risk factors of GDM is increasing; thus, it is essential to improve management of this condition. One of the key factors affecting perinatal outcomes in GDM is glycaemic control. Until recently, glucose monitoring was only available with self-monitoring of blood glucose (SMBG). However, nowadays, there is a new method, continuous glucose monitoring (CGM), which has been shown to be safe in pregnancy. Since proper glycaemia assessment has been shown to affect perinatal outcomes, we decided to perform a systematic review to analyse the role of CGM in glycaemic control in GDM. We conducted a web search of the MEDLINE, EMBASE, Cochrane Library, Scopus, and Web of Science databases according to the PRISMA guidelines. The web search was performed by two independent researchers and resulted in 14 articles included in the systematic review. The study protocol was registered in the PROSPERO database with registration number CRD42021289883. The main outcome of the systematic review was determining that, when compared, CGM played an important role in better glycaemic control than SMBG. Furthermore, glycaemic control with CGM improved qualification for insulin therapy. However, most of the articles did not reveal CGM's role in improving neonatal outcomes. Therefore, more studies are needed to analyse the role of CGM in affecting perinatal outcomes in GDM.

The aim of this study was to determine the suitability of the comparative genomic hybridization to microarray (aCGH) technique for prenatal diagnosis, but also to assess the frequency of chromosomal aberrations that may lead to fetal malformations but are not included in the diagnostic report. We present the results of the aCGH in a cohort of 7400 prenatal cases, indicated for invasive testing due to ultrasound abnormalities, high-risk for serum screening, thickened nuchal translucency, family history of genetic abnormalities or congenital abnormalities, and advanced maternal age (AMA). The overall chromosomal aberration detection rate was 27.2% (2010/7400), including 71.2% (1431/2010) of numerical aberrations and 28.8% (579/2010) of structural aberrations. Additionally, the detection rate of clinically significant copy number variants (CNVs) was 6.8% (505/7400) and 0.7% (57/7400) for variants of unknown clinical significance. The detection rate of clinically significant submicroscopic CNVs was 7.9% (334/4204) for fetuses with structural anomalies, 5.4% (18/336) in AMA, 3.1% (22/713) in the group of abnormal serum screening and 6.1% (131/2147) in other indications. Using the aCGH method, it was possible to assess the frequency of pathogenic chromosomal aberrations, of likely pathogenic and of uncertain clinical significance, in the groups of cases with different indications for an invasive test.

Purpose: The purpose of this article is to provide a modern perspective on the diagnosis of endometriosis with particular attention to the role of ultrasound examination. In the present study, we highlight the problem of endometriosis in teenage girls and discuss the patients' perspective on the diagnostic process., Methods: In order to present the most recent reports on the diagnosis of endometriosis, the PubMed database was searched. Articles published within the last 3 years (2019-2021) and those considered relevant during the bibliographic review were analyzed., Results: The role of ultrasound examination and assessment of patients' perspective related to delayed and incorrect diagnosis were considered to be the most important in the recent reports. Attention was also paid to the problem of endometriosis diagnosis in adolescent girls., Conclusions: Appropriately constructed and used questionnaires help to determine the risk of endometriosis in a particular patient. The primary method for diagnosis is extended ultrasound examination, which should be performed especially in patients with a high risk of developing the disease. This procedure is applicable to both adult and adolescent women. Awareness of the possibility of developing the disease in a particular patient, combined with appropriate use of ultrasound examination, can contribute to the decrease in diagnostic delay., Competing Interests: Declaration of competing interest The authors declare no conflict of interests., (Copyright © 2022 Medical University of Bialystok.

Aims/introduction: The aim of the present study was to evaluate the placental expression of glucose transporters GLUT-1, GLUT-3, GLUT-8 and GLUT-12 in term pregnancies complicated by well-controlled gestational (GDM) and type 1 pregestational diabetes mellitus (PGDM)., Materials and Methods: A total of 103 placental samples were obtained from patients diagnosed with GDM (n = 60), PGDM (n = 20) and a non-diabetic control group (n = 23). Computer-assisted quantitative morphometry of stained placental sections was performed to determine the expression of selected GLUT proteins., Results: Immunohistochemical techniques used for the identification of GLUT-1, GLUT-3, GLUT-8 and GLUT-12 revealed the presence of all glucose transporters in the placental tissue. Morphometric evaluation performed for the vascular density-matched placental samples demonstrated a significant increase in the expression of GLUT-1 protein in patients with PGDM as compared to GDM and control groups (P < 0.05). With regard to the expression of the other GLUT isoforms, no statistically significant differences were observed between patients from the diabetic and control populations. Positive correlations between fetal birthweight and the expression of GLUT-1 protein in the PGDM group (rho = 0.463, P < 0.05) and GLUT-12 in the control group (rho = 0.481, P < 0.05) were noted., Conclusions: In term pregnancies complicated by well-controlled GDM/PGDM, expression of transporters GLUT-3, GLUT-8 and GLUT-12 in the placenta remains unaffected. Increased expression of GLUT-1 among women with type 1 PGDM might contribute to a higher rate of macrosomic fetuses in this population., (© 2021 The Authors.

Placental transfer of glucose constitutes one of the major determinants of the intrauterine foetal growth. The objective of the present study was to evaluate the expression of glucose transporter proteins GLUT-1, GLUT-3, GLUT-8 and GLUT-12 in the placenta of macrosomic, small-for-gestational-age (SGA) and growth-restricted foetuses (FGR). A total of 70 placental tissue samples were collected from women who delivered macrosomic ≥4000 g ( n = 26), SGA ( n = 11), growth-restricted ( n = 13) and healthy control neonates ( n = 20). Computer-assisted quantitative morphometry of stained placental sections was performed to determine the expression of selected GLUT proteins. Immunohistochemical staining identified the presence of all glucose transporters in the placental tissue. Quantitative morphometric analysis performed for the vascular density-matched placental samples revealed a significant decrease in GLUT-1 and increase in GLUT-3 protein expression in pregnancies complicated by FGR as compared to other groups ( p < 0.05). In addition, expression of GLUT-8 was significantly decreased among SGA foetuses ( p < 0.05). No significant differences in GLUTs expression were observed in women delivering macrosomic neonates. In the SGA group foetal birth weight (FBW) was negatively correlated with GLUT-3 (rho = -0.59, p < 0.05) and positively with GLUT-12 (rho = 0.616, p < 0.05) placental expression. In addition, a positive correlation between FBW and GLUT-12 expression in the control group (rho = 0.536, p < 0.05) was noted. In placentas derived from FGR-complicated pregnancies the expression of two major glucose transporters GLUT-1 and GLUT-3 is altered. On the contrary, idiopathic foetal macrosomia is not associated with changes in the placental expression of GLUT-1, GLUT-3, GLUT-8 and GLUT-12 proteins.

Urinary tract infections (UTIs), defined as the presence of bacteria above the bladder sphincter, are among the most common infectious diseases. They remain a significant cause of antibiotic prescription worldwide. The incidence is much higher among women, especially of reproductive age, than among men. If the infection occurs at least 3 times a year or twice within 6 months, it is classified as recurrent urinary tract infection (rUTI). Among the causal pathogens, the vast majority are Gram-negative bacteria, the most common of which is Escherichia coli . Recommended treatment regimens differ depending on the diagnosed disease entity and the patient's clinical situation. Empirical antibiotic therapy is most often used. The first-line treatment in patients with acute simple cystitis include nitrofurantoin, trimethoprim-sulfamethoxazole, or fosfomycin. Beta-lactams and fluoroquinolones should be considered as a second-line agent. In particular cases (pregnancy or rUTIs) targeted treatment, based on the results of urine culture and antibiogram, is implemented. During pregnancy recommended treatment includes administration of cephalosporins (e.g. cefuroxime) or nitrofurantoin. In patients with uncomplicated pyelonephritis fluoroquinolones should be considered as the first-line regimen. In the case of rUTIs, there are no uniform guidelines for prophylactic management. Repeated administration of antibiotics due to infections leads to a growing problem of drug resistance. Most recommendations suggest not to use antibiotic prophylaxis routinely. Growing evidence favours non-antibiotic prophylaxis regimens for recurrent UTIs. Until now only one product - oral immunostimulant OM-89 - has been sufficiently investigated. Wider implementation of immunoprophylaxis in the future may reduce possible side effects of inappropriate antibiotic consumption., (Copyright © 2021 Termedia.)
