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.

"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.

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.

Quantitative and qualitative Ductus Venosus blood flow evaluation in the screening for Trisomy 18 and 13 - suitability study.

OBJECTIVES: The objective of the paper is the suitability assessment of screening for Trisomy 18 and 13 on the basis of nuchal translucency (NT) measurement, Fetal Heart Rate (FHR), double test, quantitative [Ductus Venosus (DV) Pulsatility Index for Veins (PIV)] and qualitative (the A-wave assessment) blood flow evaluation in the DV. MATERIAL AND METHODS: The study was performed in 7296 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 doppler ultrasound markers such as abnormal a-wave in Ductus Venosus and Pusatility Index for Veins of Ductus Venosus were and their impact on Trisomies 18 and 13 screening were 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 90.2% and FPR was 6%. Detection Rates of examined chromosomal abnormalities using contingent screening were: 92.1% using DV abnormal a-wave and 94.84% using DV-PIV. FPR's for booths parameters 5.8% and 5.4% respectively. CONCLUSIONS: Quantitative analysis of the flow - assessment of DV-PIV in the first trimester significantly influences the improvement of screening values focusing on Trisomy 18 and 13 detection.

A Retrospective Study on the Risk of Respiratory Distress Syndrome in Singleton Pregnancies with Preterm Premature Rupture of Membranes between 24+0 and 36+6 Weeks, Using Regression Analysis for Various Factors.

AIM: This study aimed to investigate the cause of respiratory distress syndrome (RDS) in neonates from singleton pregnancies with preterm premature rupture of membranes (pPROM) between 24+0 and 36+6 weeks by using regression analysis for various factors. METHODS: In 175 singleton pregnancies with pPROM, 95 cases of RDS (54,29%) were diagnosed. In all cases the following information was collected: latency period of PROM, gestational age at birth, Umbilical Artery Pulsatility Index (UA PI), Middle Cerebral Artery Pulsatility Index (MCA PI), fetal distress, antenatal steroids use, delivery type, pregnancy hypertension disease, gestational glucose intolerance or diabetes, neonatal laboratory parameters, gender, weight, Apgar score, and other neonatal complications. Logistic regression analysis was used to investigate the effect of variables on RDS. RESULTS: The results of logistic regression analysis showed that the following variables are closely correlated with RDS: female gender (OR=0.52; 95%CI:0.28-0,97), antenatal steroids use (OR=0,46; 95%CI:0,34-0,64), abnormal UA PI and MCA PI (OR=2.96; 95%CI:1,43-6,12) (OR=2.05; 95%CI:1,07-3,95), fetal distress (OR=2.33; 95%CI:1,16-4,71), maternal HGB (OR=0.69; 95%CI:0,5-0,96), and neonatal RBC, HGB (OR=0.32; 95%CI:0,19-0,55) (OR=0.75; 95%CI:0,65-0,88). CONCLUSIONS: The main RDS risk factors in premature neonates are gender, abnormal fetoplacental circulation, and fetal distress. The laboratory parameters such as lower RBC and HGB count are observed in infants with RDS.
