RESUMEN
INTRODUCTION: Placenta accreta spectrum disorders (PAS) lead to major complications in pregnancy. While the maternal morbidity associated with PAS is well known, there is less information regarding neonatal morbidity in this setting. The aim of this study is to describe the neonatal outcomes (fetal malformations, neonatal morbidity, twin births, stillbirth, and neonatal death), using an international multicenter database of PAS cases. MATERIAL AND METHODS: This was a prospective, multicenter cohort study based on prospectively collected cases, using the international multicenter database of the International Society for PAS, carried out between January 2020 and June 2022 by 23 centers with experience in PAS care. All PAS cases were included, regardless of whether singleton or multiple pregnancies and were managed in each center according to their own protocols. Data were collected via chart review. Local Ethical Committee approval and Data Use Agreements were obtained according to local policies. RESULTS: There were 315 pregnancies eligible for inclusion, with 12 twin pregnancies, comprising 329 fetuses/newborns; 2 cases were excluded due to inconsistency of data regarding fetal abnormalities. For the calculation of neonatal morbidity and mortality, all elective pregnancy terminations were excluded, hence 311 pregnancies with 323 newborns were analyzed. In our cohort, 3 neonates (0.93%) were stillborn; of the 320 newborns delivered, there were 10 cases (3.13%) of neonatal death. The prevalence of major congenital malformations was 4.64% (15/323 newborns), most commonly, cardiovascular, central nervous system, and gastrointestinal tract malformations. The overall prevalence of major neonatal morbidity in pregnancies complicated by PAS was 47/311 (15.1%). There were no stillbirths, neonatal deaths, or fetal malformations in reported twin gestations. CONCLUSIONS: Although some outcomes may be too rare to detect within our cohort and data should be interpreted with caution, our observational data supports reassuring neonatal outcomes for women with PAS.
RESUMEN
INTRODUCTION: Placenta accreta spectrum (PAS) can lead to major peripartum morbidity. Appropriate management approaches depend on the clinical severity, each individual's preference, and the treating team's expertise. Peripartum hysterectomy is the most frequently used treatment option. However, it can impact psychological well-being and fertility. We investigated whether conservative treatment with focal resection or leaving the placenta in situ is associated with comparable or lower maternal morbidity than hysterectomy in centers of excellence within the International Society for placenta accreta spectrum (IS-PAS). Furthermore, a survey was conducted to explore potential barriers to conservative management in antenatal counseling and intraoperative decision-making. MATERIAL AND METHODS: Confirmed PAS cases in the prospective IS-PAS database from 22 registered centers between January 2020 and June 2022 were included in the analysis. A separate online survey with 21 questions was answered by the IS-PAS center experts about indications, diagnostic criteria, patient counseling, surgical practice, changes from the preoperative treatment plan, and why conservative management may not be offered. RESULTS: A total of 234 cases were included in the analysis: 186 women received hysterectomy and 38 women were treated by focal resection, and 10 by leaving the placenta in situ. Blood loss was lower in the focal resection group and in the placenta in situ group compared to the hysterectomy group (p = 0.04). 46.4% of the women initially planned for focal resection, and 35.7% of those initially planned for leaving the placenta in situ were ultimately treated by hysterectomy. Our survey showed that the IS-PAS centers preferred hysterectomy according to a woman's wishes (64%) and when they expected less blood loss and morbidity (41%). Eighteen percent of centers did not offer focal resection at all due to a lack of experience with this technique. Reasons for not offering to leave the placenta in situ were avoidance of unexpected reoperation (36%), puerperal infection (32%), or skepticism about the method (23%). CONCLUSIONS: Uterus-preserving treatment strategies such as focal resection appear to be safe alternatives to peripartum hysterectomy. However, less than half of the IS-PAS centers perform them. Acceptance of conservative treatments could be increased by standardized criteria for their implementation and by systematic training for PAS experts.
RESUMEN
BACKGROUND Maternal vaccination during pregnancy reduces the risk of severe course and complications from infections both for the mother and her child. As information regarding immunization status of pregnant women with recommended vaccines in Poland is scarce, this questionnaire-based study aimed to identify influenza, pertussis (whooping cough), and COVID-19 vaccination in 205 pregnant women in Cracow, Poland, between February and April 2023. Another objective was to assess whether any of the maternal factors might influence women's decision to inoculate during pregnancy. MATERIAL AND METHODS An anonymous and self-reported questionnaire developed specifically for this study was disseminated among postpartum women, who gave birth and were hospitalized at the Department of Obstetrics and Perinatology of the University Hospital in Cracow, Poland, between February and April 2023. Study participants were asked about their basic sociodemographic and obstetric data, as well as their immunization status regarding influenza, pertussis, and COVID-19 during their most recent pregnancy. RESULTS Only 12.2% and 23.4% of study participants received influenza and pertussis vaccinations, respectively, during pregnancy, while 61.5% of pregnant women reported vaccination with at least 2 doses of the mRNA COVID-19 vaccine. Features including type of occupation, place of residence, gravidity, and parity were statistically significant (P.

INTRODUCTION: This study aimed to evaluate the occurrence of clinically relevant (sub)microscopic chromosomal aberrations in fetuses with the nuchal translucency (NT) range from 3.0 to 3.4 mm, which would be potentially missed by cfDNA testing. METHODS: A retrospective data analysis of 271 fetuses with NT between 3.0 and 3.4 mm and increased first trimester combined test (CT) risk in five cohorts of pregnant women referred for invasive testing and chromosomal microarray was performed. RESULTS: A chromosomal aberration was identified in 18.8% fetuses (1:5; 51/271). In 15% (41/271) of cases, trisomy 21, 18, or 13 were found. In 0.7% (2/271) of cases, sex chromosome aneuploidy was found. In 1.1% (3/271) of cases, CNV >10 Mb was detected, which would potentially also be detected by genome-wide cfDNA testing. The residual risk for missing a submicroscopic chromosome aberration in the presented cohorts is 1.8% (1:54; 5/271). CONCLUSION: Our results indicate that a significant number of fetuses with increased CT risk and presenting NT of 3.0-3.4 mm carry a clinically relevant chromosomal abnormality other than common trisomy. Invasive testing should be offered, and counseling on NIPT should include the test limitations that may result in NIPT false-negative results in a substantial percentage of fetuses.
RESUMEN
BACKGROUND: Massive pulmonary embolus (PE), resulting in cardiac arrest during pregnancy and postpartum, is a rare but potentially catastrophic event. The most severe manifestation of massive PE is cardiovascular instability, including cardiogenic shock and cardiac arrest requiring intensive care unit (ICU) admissions. Up to 23% of high-risk PE pregnant and postpartum patients experience cardiac arrest. CASE DESCRIPTION: Case 1, a 34-year-old obese patient, with a twin pregnancy, had cesarean sections in the 24th week of pregnancy due to premature abruption of the placenta. Immediately after the birth, she experienced a sudden cardiac arrest. Treatment was initiated in line with antimicrobial lock solutions (ALS), heparine and alteplase was administered due to suspected massive pulmonary embolism. After 20 minutes from return of spontaneous circulation (ROSC), the uterine atony and severe hemorrhage occurred, and a postpartum hysterectomy was performed. The mother and two daughters are alive in 2021. Case 2, a 24-year-old obese patient had a cesarean section due to abruption of the placenta in the 28th week of pregnancy. Twelve hours after cesarean delivery, the patient's condition suddenly deteriorated. The patient reported dyspnea, chest pain, and presented cyanosis. The blood pressure was 66/30 mmHg, heart rate 130/min, tachypnea with a respiratory rate of 30/min, saturation 80% on air. High flow oxygen via face mask with reservoir (FiO2 0.85) and ephedrine 2×10 mg i.v. were administered. Due to suspected pulmonary embolism, a bolus of 5,000 IU of heparin was administered iv. Despite the implemented measures, cardiac arrest was confirmed with the initial rhythm of pulseless electrical activity (PEA) (sinus tachycardia 120/min). Treatment consistent with ALS was initiated. Due to the high probability of pulmonary embolism, a bolus of alteplase was administrated. ROSC was obtained 7 minutes later. Because of obstetric hemorrhage hysterectomy was performed. The mother and the baby are alive in 2022. CONCLUSIONS: In light of current evidence, presented data suggest that early and aggressive recombinant thrombolytic use in case of cardiac arrest and suspected PE in obstetric patients may be life-saving, effective treatment with a good neurological outcome. Major bleeding complications should be anticipated when administering this therapy.
RESUMEN
OBJECTIVES: Labor induction is one of the most common procedures in modern obstetrics. One in five pregnant women and 30-40% of women delivering vaginally undergo this procedure. If the cervical status is unfavorable, a ripening process is used prior to induction to shorten the duration of oxytocin administration and maximize the possibility of vaginal birth. The aim of this study was to compare the duration of labor induced with dinoprostone vaginal insert to spontaneous labor. MATERIAL AND METHODS: It was a retrospective study conducted between May 2019 and February 2021 in the tertiary reference center, the Obstetrics and Perinatology Department of the Jagiellonian University Hospital in Krakow. The research group involved 182 patients in singleton pregnancy at term, qualified for cervical ripening procedure. The control group consisted of 178 patients that were delivering spontaneously and admitted to the delivery ward in the first stage of labor. Statistical analysis was performed to compare the duration of labor between groups. To find factors affecting the procedure we compared different models consisting of maternal and fetal characteristics. RESULTS: Successful vaginal delivery in the dinoprostone group was achieved in the group of 88% of patients. There was no significant difference in labor duration between the groups: 315 minutes in the study group and 300 min in the control group. Only being primipara was a factor related to longer labor in both groups. CONCLUSIONS: Pre-induction with dinoprostone insert and additional foley catheter, if indicated, does not make labor longer in comparison with spontaneous labor.

OBJECTIVES: The SARS-CoV-2 virus infection has spread to almost all countries in the last two years. Pregnancy complicated with COVID-19 is a unique situation and challenge for doctors. The study aimed to evaluate obstetric results, and biochemical test results and to analyze the treatment used in pregnant patients complicated with COVID-19 infection. MATERIAL AND METHODS: A retrospective analysis of 146 pregnant patients hospitalized at the Department of Obstetrics and Perinatology Jagiellonian University Medical College (JUMC) in Krakow was conducted from July 2020 to August 2021. RESULTS: In the analyzed group respiratory failure occurred in 19.19% of cases and intravascular coagulation syndrome (DIC) in 1.37%. One patient died (0.68%). 16.6% of cases were transferred to the Intensive Care Unit (ICU) and required intubation. The remaining cases were mild: 39.04% were asymptomatic, 41.78% reported cough, 30.82% dyspnoea and 23.97% myalgia. In the laboratory tests increased values of CRP and IL-6 were observed with normal levels of leukocytes. Additionally, a decreased level of total protein and an increased level of d-dimers were detected. 98.63% of patients received a prophylactic dose of low molecular weight heparin. 46.58% of cases needed additional antibiotic therapy. Cesarean sections were performed in 59.59% of cases. The children were born in good general condition. Vertical transmission of SARS-CoV-2 to the newborn has not been confirmed. CONCLUSIONS: Data from the above study show a significant effect of COVID-19 on pregnant patients. Almost one in five pregnant women occurred respiratory failure and most of them had to be transferred to the ICU department and had to be intubated.

OBJECTIVES: The aim of this study was to evaluate the effectiveness of labour preinduction using a dinoprostone vaginal insert in patients with gestational diabetes mellitus versus patients undergoing labour induction for other causes. The second aim of the study was to compare perinatal outcomes in both groups. MATERIAL AND METHODS: The study has a retrospective character, conducted in 2019-2021 in a tertiary reference hospital. The following endpoints were assumed for the analysis: natural childbirth, birth occurring within 12 hours of dinoprostone administration and neonatal outcomes. Furthermore, indications of a Caesarean section were analysed. RESULTS: The percentage of natural childbirths was similar in both groups. Furthermore, in both groups, over 80% of patients gave birth within less than 12 hours following dinoprostone administration. Neonatal outcomes (body weight, Apgar score) did not differ statistically. Analysing indications for a Caesarean section, failure in the progress of labour was an indication in 39.5% of cases in the control group, 29.4% of cases in gestational diabetes mellitus (GDM), and 50% of cases in diabetes mellitus (DM). The risk of foetal asphyxia was an indication in 55.8% of cases in the control group, 35.3% of cases in GDM and 50% of cases in DM. Ineffective labour induction - no induction of the contractile function was an indication for a C-section in 4.7% of cases in the control group and 35.3% of cases in GDM; no cases were noted in DM (p = 0.024). CONCLUSIONS: The study demonstrated that patients undergoing labour induction due to GDM using a dinoprostone vaginal insert did not differ in terms of labour duration, oxytocin administration compared to patients undergoing labour induction for other causes. Furthermore, the same rate of Caesarean sections was found in the study group; however, these groups differ in terms of indications, including risk of foetal asphyxia (35.3% vs 55.8%), failure in the progress of labour (29.4% vs 39.5%), and no active labour (1.8% vs 1.5%). The neonatal Apgar score at 1.5 and 10 minutes after birth was similar in both groups.
RESUMEN
OBJECTIVES: Numerous physical and chemical processes lead to rupture of membranes. Within the fetal membranes there are numerous types of metalloproteinases, which cause collagen type I degradation. The C-terminal telopeptide of colagen type I (ICTP) is the breakdown product of type I collagen. The aim of the study was to determine whether ICTP is secreted into the vaginal-cervical fluid (VCF) in the case of physiological rupture of the membranes of the fetus before delivery. MATERIAL AND METHODS: The study was conducted in March 2021 at the Department of Obstetrics and Perinatology of the Jagiellonian University in Cracow, Poland. Twenty-three cases were included in the study. During routine gynecological examination with the use of specula, VCF was collected twice in a volume of 50 µL. The obtained material was then subjected to enzyme immunoassay using the Human C-telopeptide of type I collagen (ICTP) ELISA Kit (Catalog Number. CSB-E10363h). The concentration of ICTP in the sample was calibrated. The concentration range that the device can detect was 25 ng /mL-800 ng/mL. RESULTS: The presence of ICTP in the VCF was confirmed. The minimum concentration was 43.72 ng/mL, the maximum was 762.59, in five cases the concentration was outside the maximum scale of the device. CONCLUSIONS: ICTP was confirmed in the VCF of pregnant women before physiological delivery. Further studies are required to accurately evaluate ICTP as a marker of the processes of collagen degradation in fetal membranes in the mechanism of physiological labor and premature rupture of the membranes.
RESUMEN
There are many benefits of neuraxial anesthesia (NA) in the obstetric population. We performed a retrospective analysis of anesthesia provided to obstetric patients in the tertiary care center between 1 January 2014 and 31 December 2020 and the influence of the COVID-19 pandemic on anesthetic practice. A total of 15,930 anesthesia procedures were performed. A total of 2182 (17.52%) cesarean sections (CS) required general anesthesia (GA), including 383 (3.07%) of emergency conversion from NA. NA for CS consisted of 9971 (80.04%) spinal anesthesia (SA) and 304 (2.44%) epidural anesthesia (EPI). We found a decrease in the GA rate for CS in 2020 (11.87% vs. 14.81%; p < 0.001). The conversion rate from NA to GA for CS was 2.39% for SA and 31.38% for EPI. The conversion rate from labor EPI to SA for CS increased in 2020 (3.10% vs. 1.24%; p < 0.001), as well as the SA rate for other obstetric procedures (61.32%; p < 0.001). We report 2670 NA for vaginal delivery, representing 31.13% of all vaginal deliveries. NA constituted the vast majority of obstetric anesthesia. However, we report a relatively high incidence of GA. There was a decrease in GA use in the obstetric population during the pandemic. Further reduction in GA use is possible, including an avoidable conversion from NA to GA.
RESUMEN
Fetal growth restriction (FGR) is a complication of pregnancy connected with increased risk of intrauterine fetal demise. To increase the diagnostic accuracy, the cerebral placental ratio (CPR) is used. Vitamin D may play a role in the regulation of vascular flow in the fetus. The aim is to assess the relationship between CPR and vitamin D supplementation in fetuses with early FGR. It is a prospective cohort study. Pregnant females were divided into groups with 2000 IU and <500 IU of vitamin D. Both groups were observed for 14 days; USG was performed three times with one-week intervals. EFW and CPR were measured. Absolute CPR values were initially observed to differ significantly (p = 0.0032). Measurements on the seventh day of observation indicated that CPR was significantly higher (p = 0.0455) in fetuses of patients receiving vitamin D at a dose of 2000 IU 1.75 (IQR: 1.47; 2.06) vs. <500 IU group 1.55 (IQR: 1.04; 1.52). Similarly, on day 14: (p < 0.0001)2.39 (IQR: 1.82; 2.69) vs. 1.21 (IQR: 0.98; 1.52). Supplementation with vitamin D at a dose of 2000 IU may have an influence on the increase in the CPR in fetuses with early FGR.
RESUMEN
BACKGROUND: Fetal growth restriction (FGR) increases the risk of intrauterine fetal death, infant death and complications in childhood, and diseases that appear in adulthood. Vitamin D may affect fetal vascular flow. The aim of the study was to check if the rate of fetal growth in pregnant women with FGR differs depending on whether the patient was supplemented with vitamin D in the recommended dose of 2000 IU, not supplemented at all, or supplemented with vitamin D in low doses. METHODS: Patients were divided into two groups: suboptimal vitamin D dosage and an accurate dosage of 2000 IU. Fetal growth progress was observed for 14 days. RESULTS: Fetal weight was higher at the beginning, after 1 and 2 weeks of observation in the optimal vit. D group compared with the suboptimal group. The analysis was adjusted to the mother's age, gestational week, and the number of pregnancies. CONCLUSIONS: Greater fetal weight gain can be observed in women with FGR (fetal growth restriction) who intake vitamin D at the recommended dose of 2000 IU compared with women with FGR and with a vitamin D intake dosage lower than 500 IU.
RESUMEN
Coagulopathies are one of the obstetric complications affecting the period of pregnancy, childbirth, and puerperium. One of the more severe and complex disorders of the haemostatic system is the disseminated intravascular coagulation syndrome (DIC), in which generalised activation of the coagulation system and activation of inflammatory cells occurs. DIC syndrome was observed in patients whose pregnancy was complicated by SARS-CoV-2 infection. Both the course of these cases and literature review indicate that particular notice should be paid to laboratory parameters of the coagulation system, closely monitoring the well-being of the foetus and, in the situation of acute DIC development, it is advised to deliver a baby and initiate intensive therapy.
RESUMEN
OBJECTIVES: Computer CTG analysis (cCTG) included short-term variation (STV) is one of the methods of monitoring fetal condition during delivery. The aim of our study was to define appropriability of STV measured within 1 hour before delivery in prediction of neonatal outcomes. MATERIAL AND METHODS: The retrospective study included 1014 pregnant women, who gave birth in the Department of Obstetrics and Perinatology. Participants were divided into two groups: group 1 - term pregnancies (37-41 weeks) and group 2 - preterm pregnancies (lower than 37 weeks). In each of them, two subgroups have been separated: control (STV ≥ 3 ms) and study group (STV < 3 ms). RESULTS: In both groups 1 and 2, there were no statistically significant differences related to Apgar scores in 1st, 3rd and 5th minute between group with STV < 3 ms and group with STV > 3 ms Moreover, for 37-41 weeks the sensitivity, specificity, positive predictive value and negative predictive value were: 22.7%, 83.9%, 3.3% and 97.8% and for lower than 37: 45.7%, 65.4%, 47.1%, 64.2% in 1st minute after delivery. In group 1 the area under curve (AUC) measurements were 0.45 (95% CI: 0.32-0.58) for 1st minute and 0.55 (95% CI: 0.35-0.74) for 5th minute and in group 2: 0.58 (95% CI: 0.45-0.71) for 1st minute and 0.57 (95% CI: 0.42-0.72) for 5th minute. CONCLUSIONS: High specificity and negative predictive value of STV indicates a good Apgar score of newborns in term pregnancies. Analysis of STV in preterm pregnancy is not clear. Fetal well-being in preterm pregnancy should include STV and other non-invasive and invasive tools.

Central nervous system (CNS) abnormalities cause about 40% of infant deaths in the first year of life. In case of the detection of abnormalities by ultrasound, a pregnant woman should be offered prenatal magnetic resonance imaging (pMRI). The aims of our study were: (1) to evaluate the effectiveness of pMRI in the diagnosis of selected fetal CNS defects; and (2) to assess the possibility of replacing postnatal tests with prenatal magnetic resonance. The prospective and observational study was conducted between 2014 and 2017 at the University Hospital in Krakow. Patients with suspected CNS defects of the fetus were qualified for pMRI in the third trimester of pregnancy. Sixty patients were included in the study group. Prenatal MRI was characterized by low accuracy in the diagnosis of complex brain defects. Cohen's kappa coefficient κ = 0.21 (95% CI 0.00-0.46). No evidence was found suggesting the replacement of postnatal tests with pMRI. MRI was characterized by low consistency of diagnoses in the case of complex brain defects. The possibility of replacing postnatal studies with pMRI was not supported.
