Blood type ABO and the cytokine profile of follicular fluid in women undergoing IVF/ET.

OBJECTIVES: ABO blood type was hypothesised to be related to a number of infertility processes. There is still an open debate on ABO blood group's incompatibility and infertility. It was associated with ovarian reserve in women with subfertility. There is still not enough information on the influence of blood type and the immunology of follicular fluid (FF). MATERIAL AND METHODS: 78 patients were selected, who underwent in vitro fertilization (IVF) between April 2021 and January 2022. FF samples from each individual patient were taken on the day of ovarian puncture and stored at -80°C until immunological assessment. Concentration of chosen interleukins - IL-1α, IL-2, IL-4, IL-5, IL-6, IL-8 IL-10, IL-15, IL-1ß, IL-18, IFN, LIF, TNFα, GCSF and PIBF-1 were measured using commercially available ELISA kits. RESULTS: All assessed cytokines were present in the FF of exanimated patients. The concentration was compared to the blood type ABO of all women undergoing in vitro fertilization. No statistical relevance was found between blood type ABO and the concentration of GCSF, PIBF1, LIF, IL-15, IL-5, IL-8, IL-1 alfa, IL-1 beta, INF gamma, IL-2HS, IL-4HS, IL-6HS, IL-10HS in the FF obtained during ovarian puncture (p > 0,05). There was no statistically significant correlation between blood type ABO and the quality of embryo, and the positive pregnancy test in patients undergoing IVF/ET. CONCLUSIONS: The blood type ABO does not influence the wide cytokine profile of FF obtained during ovarian puncture in women with infertility of different origin, as well as embryo quality and pregnancy rate.

Ductus venosus opens in high-risk pregnancies without signs of increased central venous pressure.

OBJECTIVES: It has been belived that changes in diastolic blood velocities in the fetal ductus venosus were due to increased central venous pressure secondary to increased fetal heart strain during hypoxia or heart failure. There have been recent reports of changes in ductus venosus blood velocity without signs of increased fetal heart strain. The aim of this evaluation was to compare blood velocity in the right hepatic vein as a marker of increased central venous pressure in relationship to changes in ductus venosus blood velocity. MATERIAL AND METHODS: Fifty pregnancies suspected of fetal growth resitriction were evaluated by Doppler ultrasound. Blood velocity was recorded in the right hepatic vein, ducus venosus and in the umbilical vein. Placental blood flow was also recorded in the uterine and umbilical arteries as well as the fetal middle cerebral artery. RESULTS: Increased umbilical artery pulsatility index was recorded in 19 fetuses and 20 has signes of brain sparing according to recordings in the middle cerebral artery. Abnormal blood velocity in the ductus venosus was recorded in 5 fetuses, none of these fetuses had an abnormal pulsatility in the right hepatic vein. CONCLUSIONS: Opening of the ductus venosus is not only related to fetal cardiac strain. This might indicate that the ductus venosus does not primarily open due to increased central venous pressure in moderate fetal hypoxia. Increased fetal cardiac strain might be a late event in the process of chronic fetal hypoxia.

The use of CO2 laser in vulvar lichen sclerosus treatment - molecular evidence.

Vulvar lichen sclerosus is chronic and difficult to treat disorder, which offer is recurrent and leads to multiple complications. The limited efficacy of pharmacologic treatment directed the search for new therapies including use of CO2 laser. In our study we focused on collagen and elastin gene expression as well as heat shock proteins and p53 expression in two patients with vulvar lichen sclerosus who underwent CO2 laser therapy. In both patients we observed decreased clinical symptoms observed by an experienced gynecologist as well as significant changes in gene expression before and after laser treatment.

Influence of gestational diabetes in twin pregnancy on the condition of newborns and early neonatal complications.

OBJECTIVES: Diabetes mellitus is the most common metabolic complication in pregnancy and increasing worldwide. In Europe, it occurs in 3-5% of pregnant women. The rate of twin pregnancy has been increased similarly to gestational diabetes mellitus (GDM). Twin pregnancy is associated with a higher complication rate compared to singleton pregnancy. The growing prevalence of GDM and twin pregnancy has given rise to their increasing concurrent presentation. MATERIAL AND METHODS: The retrospective analysis included 212 twin-pregnant patients. The analysis excluded cases of miscarriage and early fetal death in the first trimester of pregnancy. The influence of GDM on the condition of newborns and mothers after delivery was analyzed. For statistical analysis R 3.6.2 software was used. RESULTS: No statistically significant relationship between GDM and Non-GDM group and periparturient complications was found. Birth weight was significantly higher in the GDM G2 group. Apgar Score was the lowest in the GDM G1 group. In the group of larger newborns of the GDMG1 group respiratory distress syndrome (RDS) , a higher incidence of second-degree intracranial bleeding and grade II of preterm retinopathy were observed. There was no statistically significant relationship between GDM G1, GDM G2 and other neonatal complications. CONCLUSIONS: In summary, our results indicate that GDM in twin pregnancy does not increase the risk of cesarean section but increases some neonatal complications. In conclusion women with twin pregnancies complicated by GDM require specialist care during pregnancy and childbirth should take place in a third-level reference center.

Health-Related Quality-of-Life among Pregnant Women after First, Second, and Multiple Cesarean Sections in the Perinatal Period: A Short-Term Longitudinal Study.

The primary objective of this study was to compare assessments of health-related quality-of-life (HRQoL) in women who had a medical qualification for cesarean section (CS), depending on the number of CSs in their medical history. A short longitudinal study was conducted among 115 women on the day before a planned cesarean section (CS)-T1, and on the third day after CS-T2. They were divided into three groups. G1: no CS (n = 17); G2: one CS (n = 34); G3: two or more CSs (n = 64). Participants completed a set of questionnaires concerning sociodemographic aspects and psychological outcomes: the HRQoL questionnaire (EQ-5D-3L). A chi-square test, McNemar's test, and repeated measures ANOVA were used to compare the three groups in T1 and T2. Regardless of the number of CSs, before a CS, women mainly experience health problems with pain and anxiety/depression, and after a CS, mostly problems with pain, usual activity, and mobility. All participants experienced an increase in the amount of health problems with mobility and pain after a CS. Women who have had two or more CSs also had problems with self-care and usual activities. Women who have had one or two CSs experienced a decrease in the general assessment of the HRQoL, which is not observed in the group of women with multiple CSs. However, the HRQoL of women in the group with multiple CSs was lower before the CS than in the other groups. The results indicated the significance of the number of CSs, not only in postoperative, but also in preoperative HRQoL.

First-Trimester Fetal Hepatic Artery Examination for Adverse Outcome Prediction.

OBJECTIVE: To assess whether there are differences in first-trimester fetal hepatic artery flows depending on pregnancy outcomes. METHODS: The prospective study conducted in 2012-2020 included 1841 fetuses from singleton pregnancies assessed during the routine first-trimester ultrasound examination (between 11- and 14-weeks' gestation). Also, each fetus was examined to determine their hepatic artery flows by measuring the artery's pulsatility index (HA-PI) and peak systolic velocity (HA-PSV). RESULTS: The fetuses that were classified as belonging to the adverse pregnancy outcome group (those with karyotype abnormalities and congenital heart defects) were characterized by a significantly lower HA-PI and higher HA-PSV compared to normal outcome fetuses. CONCLUSION: Hepatic artery flow assessment proved to be a very useful tool in predicting adverse pregnancy outcomes, in particular karyotype abnormalities and congenital heart defects.

Evaluation of the Risk of Birth Defects Related to the Use of Assisted Reproductive Technology: An Updated Systematic Review.

Fertility problems constitute a serious medical, social, and demographic problem. With this review, we aim to critically appraise and evaluate the existing literature surrounding the risk of birth defects in offspring conceived using techniques based on assisted reproductive technology (ART). Based on searches of the literature in PubMed and ScienceDirect, we obtained a total of 2,003,275 works related to the topic. Ultimately, 11 original papers published in the last 10 years qualified for inclusion in the study. Based on five studies included in this analysis, it was shown that ART significantly increases the risk of congenital malformations in associated newborns. Due to the specifics of given studies, as well as potential confounding risk factors, this influence cannot be ignored. Therefore, considering the information contained in the articles included in this systematic review, it was determined that the risk of birth defects is not directly related to the use of ART itself but also depends on the age of partners, causes of infertility, comorbidities, and the number of fetuses during a pregnancy, as well as many other factors not covered in the literature. It is thus necessary to impress upon infertile couples who wish to have offspring that the use of ART is not risk-free but that the benefits outweigh the risks. Further education in this field, as well as social understanding, is also required.

Implementation of the Publicly Funded Prenatal Screening Programme in Poland during the COVID-19 Pandemic: A Cross-Sectional Study.

The COVID-19 pandemic in 2020 affected the entire healthcare system in Poland, causing medical personnel to be relocated to other duties and limiting patients' contacts with healthcare professionals. A large part of the planned diagnostics and treatment was delayed due to lack of equipment and personnel. Against this background, we analysed the implementation of the publicly funded prenatal screening programme (PSP) in Poland compared to the previous year. This is a cross-sectional study. We used nationwide datasets on the implementation of the prenatal testing programme over the period 2019−2020, datasets from the Statistics Poland on birth and the data on the development of the COVID-19 epidemic in Poland. In the year 2020, we observed a 12.41% decrease in woman enrolled to the programme compared to 2019. However, the decrease concerned only women under 35 years of age. With respect to the number of deliveries in the calendar year, the number of patients enrolled in the programme decreased by 3% (31% vs. 34%, p < 0.001). We also observed an increase in estriol measurements per the number of patients included in the programme, and a reduction in the number of PAPP-A tests in the first trimester, which proves an increased share of the triple test in the prenatal diagnosis of chromosomal aberrations. With respect to the number of deliveries, the number of amniocentesis procedures performed under PSP decreased by 0.19% (1.8% vs. 1.99%, p < 0.0001). In 2020, compared to the previous year, the number of patients included in the prenatal testing programme in Poland decreased. In terms of the number of births in Poland, the number of integrated screening tests also decreased, at the expense of increasing the percentage of triple tests. There were also significant reductions in the number of invasive diagnostic tests.

Hyperglycemia in pregnancy - prevalence and perinatal outcomes. A retrospective multicenter cohort study in Poland.

OBJECTIVES: Hyperglycemia in pregnancy (HIP) is one of the most common complications of pregnancy. Recently adopted new criteria for the diagnosis of HIP as well as the greater prevalence of risk factors could have a significant impact on HIP prevalence. The objective of the study was to assess the rates of HIP and the associated complications. MATERIAL AND METHODS: This was a retrospective analysis of clinical records from pregnant women who delivered in eight tertiary hospitals in Poland in 2016. RESULTS: The number of pregnant women with hyperglycemia totaled 1280 (7.25%), including gestational diabetes mellitus (GDM) in 1169 (6.62%) women and pregestational diabetes mellitus (PGDM) in 111 (0.63%). In addition to dietary modifications, 477 (41% of the GDM group) women received medical treatment (GDMG2). In women with PGDM multiple daily insulin injections (MDI) were used in 53 (47.7%) cases, continuous subcutaneous insulin infusions (CSII) in 57 (51.3%) cases and one woman was treated with metformin. The rate of cesarean sections was 69.4% and 62.9% for PGDM and GDM, respectively. Large-for-gestational-age (LGA) infants accounted for 38% and 21% of births in the PGDM and GDM groups, respectively. Of note are high rates of hyperbilirubinemia in infants born to mothers treated with insulin (13.5% for PGDM and 14.4% for GDMG2) vs infants born to mothers with diet (GDMG1) (3.4%). CONCLUSIONS: In Poland, the prevalence of HIP has nearly doubled in the past twenty years. Even with appropriate management, HIP is a significant risk factor for a cesarean section delivery, bearing an LGA infant and adverse neonatal outcomes.

The role of individual blood flow parameters through ductus venosus in the first and second trimesters of pregnancy in predicting the condition of the fetus and newborn.

OBJECTIVES: To predict fetal and neonatal outcome during pregnancy based on detailed analysis of ductus venosus blood flow velocities in first and second-trimester fetuses. MATERIAL AND METHODS: A retrospective analysis was made in 680 patients with single pregnancies in years 2015 and 2016. The following ductus venosus blood flow velocities in first and second-trimester were analyzed: S-wave velocity, D-wave velocity, a-wave velocity, Tmax velocity, PIV. Results were divided into sub-groups with reduced value, normal value and increased value and compared with fetal and neonatal condition. RESULTS: The relationship between the increased PIV value in the first trimester of pregnancy and an increased risk of chromosomal aberrations was observed, whereas the increased DV PI value in the second trimester of pregnancy with reduced A -wave were associated with a higher incidence of FGR. No correlation between the remaining DV blood flow velocities in the first and second trimester of pregnancy and the more frequent occurrence of fetal and neonatal complications has been confirmed. CONCLUSIONS: The increased DV PIV is a good prognostic tool for the detection of chromosomal aberrations in first trimester of pregnancy. In the second trimester, the increased DV PIV and the reduced A- wave velocity correlate with the fetal growth restriction. Ductus venosus seems to be an indirect indicator of intrauterine hypoxia with moderate prognostic value for adverse obstetric outcomes.

"The Killer Placenta" - a threat to the lives of young women giving birth by cesarean section.

OBJECTIVES: It is necessary to create a universal algorithm for the management of placenta accreta spectrum in order to minimize morbidity and mortality in young patients giving birth by caesarean section. MATERIAL AND METHODS: This was a retrospective study of seven women before the age of 30 selected out of larger group of 40 pregnant patients. The patients were hospitalized in the Clinical Department of Perinatology, Gynecology and Obstetrics in Ruda Slaska, which is a 3rd level reference department. The inclusion criterion was the suspicion of placent accreta spectrum, based on clinical condition, ultrasound examination and magnetic resonance imaging. RESULTS: A patient with a diagnosed placenta accreta spectrum should be provided with a highly specialized 3rd level referential center by an experienced multidisciplinary team of specialists. There should be free access to the blood bank, adult intensive care unit and neonatal intensive care unit. According to the results of this study, the recommended time of cesarean section is 34 + 0 - 36 + 6 weeks of pregnancy. Hysterectomy after the cesarean section is a method of choice for a placenta increta or percreta. It is the most difficult surgery in obstetrics, with a high risk of intraoperative complications. Damage to the urinary system is the most common complication of perinatal hysterectomy. Preoperative placement of ureteral catheters reduces the risk of intraoperative damage. CONCLUSIONS: It is necessary to plan individual procedure for women who has low-lying or previa placenta, and who has history of prior cesarean section - in this group the risk of placenta accreta spectrum is higher.

Prediction of preterm birth using PAMG-1 test: a single centre experience - preliminary report.

OBJECTIVES: Placental alpha microglobulin-1 (PAMG-1) is a novel biomarker detected in cervicovaginal discharge in patients threatened with preterm birth (PTB). This study aimed to show a single centre experience of assessment of imminent spontaneous PTB risk in patients with symptoms suggesting preterm labour (PTL). MATERIAL AND METHODS: The study group consisted of 46 women with singleton pregnancies between 24 + 0/7 and 33 + 6/7 weeks of gestation who presented with symptoms of threatened PTL, with cervical dilatation of < 3 cm, cervical length (CL) of < 30 mm and clinically intact fetal membranes. CL was measured via transvaginal ultrasound and the PAMG-1 test was performed in all of the objectives. RESULTS: Sensitivity (SN), specificity (SP), positive predictive value (PPV) and negative predictive value (NPV) of prediction of PTB within seven days for CL were 100%, 11.11%, 5.88% and 100%, respectively. The PAMG-1 test SN, SP, PPV and NPV of the same endpoint were 50%, 80.56%, 12.5% and 96.67%, respectively. CONCLUSIONS: PAMG-1 is a more accurate predictor of PTB when compared to CL. Routine use of both mentioned tests could allow identification of low-risk patients and reduction of rate of unnecessary hospitalizations and treatments.

Factors associated with fear of childbirth among Polish pregnant women.

The purpose of our study was to elucidate the association between obstetric and psychological factors and fear of childbirth (FOC) during the third trimester of pregnancy and to identify women at risk of severe FOC in Poland. An additional goal of the study was to verify the Polish version of the Wijma Delivery Expectancy Questionnaire (W-DEQ) and to establish its psychometric characteristics. Cross-sectional study with a total of 359 women recruited during routine visits to an antenatal clinic in Poland during the third trimester (≥ 27 weeks gestation). The survey included obstetric details (parity, obstetric history and preferred mode of delivery), and standardized psychological measures: the W-DEQ (fear of childbirth) and the EPDS (depressive symptoms). We demonstrated the satisfactory psychometric properties of the Polish version of the W-DEQ. Our findings confirm the one-factor structure found by the authors of the original version of the scale. A greater FOC was reported by women with unplanned pregnancies, women whose preferred mode of delivery was a cesarean section, and women who had previously undergone psychiatric treatment. The risk factors for severe FOC were depression, unplanned pregnancy or parity, and disagreement with the birth plan proposed by the obstetrician. The W-DEQ is a widely used, valid instrument for the assessment of FOC in pregnant women and can be used in Poland. Findings support the key role of obstetric and psychological variables in predicting fear of childbirth.

Nasal bone in screening for Trisomy 18 and 13 at 11-13 + 6 weeks of gestation - own experiences.

OBJECTIVES: The objective of the paper is the suitability assessment of screening for Trisomy 18 and 13 on the basis of NT measurement, FHR, double test and assessment of Nasal Bone. MATERIAL AND METHODS: The study was performed in 6,661 singleton pregnancies. In each fetus NT, FHR, DV-PIV were examined. Double test from maternal blood was examined. These ultrasound and biochemical factors were in combined screening investigated. Additional ultrasound marker - Nasal Bone was and its impact on Trisomies 18 and 13 screening was examined. RESULTS: Two groups of patients were compared - with chromosomal normal and chromosomal abnormalities - Trisomy 18 and 13. Detection Rate of Trisomies 18 and 13 at the risk cutoff 1/300 using combined screening was 84.1% and FPR was 7.1%. Detection Rates of examined chromosomal abnormalities using screening with additional marker - NB was 93.2% and False Positive Rate - 5.6%. CONCLUSIONS: It should be noted that the qualitative analysis of the assessment of NB in the first trimester significantly influences the improvement of screening values focusing on Trisomy 18 and 13 detection. In summary, our research indicates a more effective type of Trisomy 13 and 18 screening using NT, double test, maternal age, CRL and FHR as well as nasal bone presence and absence.
