Multicentre randomised trial of screening with sFlt1/PlGF and planned delivery to prevent pre-eclampsia at term: protocol of the PE37 study

INTRODUCTION

Pre-eclampsia affects ~5%-7% of pregnancies. Although improved obstetric care has significantly diminished its associated maternal mortality, it remains a leading cause of maternal morbidity and mortality in the world. Term pre-eclampsia accounts for 70% of all cases and a large proportion of maternal-fetal morbidity related to this condition. Unlike in preterm pre-eclampsia, the prediction and prevention of term pre-eclampsia remain unsolved. Previously proposed approaches are based on combined third-trimester screening and/or prophylactic drugs, but these policies are unlikely to be widely implementable in many world settings. Recent evidence shows that the soluble fms-like tyrosine kinase-1 (s-Flt-1) to placental growth factor (PlGF) ratio measured at 35-37 weeks' gestation predicts term pre-eclampsia with an 80% detection rate. Likewise, recent studies demonstrate that induction of labour beyond 37 weeks is safe and well accepted by women. We hypothesise that a single-step universal screening for term pre-eclampsia based on sFlt1/PlGF ratio at 35-37 weeks followed by planned delivery beyond 37 weeks reduces the prevalence of term pre-eclampsia without increasing the caesarean section rates or worsening the neonatal outcomes.

METHODS AND ANALYSIS

We propose an open-label randomised clinical trial to evaluate the impact of a screening of term pre-eclampsia with the sFlt-1/PlGF ratio followed by planned delivery in asymptomatic nulliparous women at 35-37 weeks. Women will be assigned 1:1 to revealed (sFlt-1/PlGF known to clinicians) versus concealed (unknown) arms. A cut-off of >90th centile is used to define the high risk of subsequent pre-eclampsia and offer planned delivery from 37 weeks. The efficacy variables will be analysed and compared between groups primarily following an intention-to-treat approach, by ORs and their 95% CI. This value will be computed using a Generalised Linear Mixed Model for binary response (study group as fixed effect and the centre as intercept random effect).

ETHICS AND DISSEMINATION

The study is conducted under the principles of Good Clinical Practice. This study was accepted by the Clinical Research Ethics Committee of Hospital Clinic Barcelona on 20 November 2020. Subsequent approval by individual ethical committees and competent authorities was granted. The study results will be published in peer-reviewed journals and disseminated at international conferences.

Term planned delivery based on fetal growth assessment with or without the cerebroplacental ratio in low-risk pregnancies (RATIO37): an international, multicentre, open-label, randomised controlled trial

BACKGROUND

The cerebroplacental ratio is associated with perinatal mortality and morbidity, but it is unknown whether routine measurement improves pregnancy outcomes. We aimed to evaluate whether the addition of cerebroplacental ratio measurement to the standard ultrasound growth assessment near term reduces perinatal mortality and severe neonatal morbidity, compared with growth assessment alone.

METHODS

RATIO37 was a randomised, open-label, multicentre, pragmatic trial, conducted in low-risk pregnant women, recruited from nine hospitals over six countries. The eligibility criteria were designed to be broad; participants were required to be 18 years or older, with an ultrasound-dated confirmed singleton pregnancy in the first trimester, an alive fetus with no congenital malformations at the routine second-trimester ultrasound, an absence of adverse medical or obstetric history, and the capacity to give informed consent. Women were randomly assigned in a 1:1 ratio (block size 100) using a web-based system to either the concealed group or revealed group. In the revealed group, the cerebroplacental ratio value was known by clinicians, and if below the fifth centile, a planned delivery after 37 weeks was recommended. In the concealed group, women and clinicians were blinded to the cerebroplacental ratio value. All participants underwent ultrasound at 36 + 0 to 37 + 6 weeks of gestation with growth assessment and Doppler evaluation. In both groups, planned delivery was recommended when the estimated fetal weight was below the tenth centile. The primary outcome was perinatal mortality from 24 weeks' gestation to infant discharge. The study is registered at ClinicalTrials.gov (NCT02907242) and is now closed.

FINDINGS

Between July 29, 2016, and Aug 3, 2021, we enrolled 11 214 women, of whom 9492 (84·6%) completed the trial and were eligible for analysis (4774 in the concealed group and 4718 in the revealed group). Perinatal mortality occurred in 13 (0·3%) of 4774 pregnancies in the concealed group and 13 (0·3%) of 4718 in the revealed group (OR 1·45 [95% CI 0·76-2·76]; p=0·262). Overall, severe neonatal morbidity occurred in 35 (0·73%) newborns in the concealed group and 18 (0·38%) in the revealed group (OR 0·58 [95% CI 0·40-0·83]; p=0·003). Severe neurological morbidity occurred in 13 (0·27%) newborns in the concealed group and nine (0·19%) in the revealed group (OR 0·56 [95% CI 0·25-1·24]; p=0·153). Severe non-neurological morbidity occurred in 23 (0·48%) newborns in the concealed group and nine (0·19%) in the revealed group (0·58 [95% CI 0·39-0·87]; p=0·009). Maternal adverse events were not collected.

INTERPRETATION

Planned delivery at term based on ultrasound fetal growth assessment and cerebroplacental ratio at term was not followed by a reduction of perinatal mortality although significantly reduced severe neonatal morbidity compared with fetal growth assessment alone.

Using Robson classification to analyze cesarean section and induction rates in relation to changes in the standards of perinatal care in one hospital in Poland

BACKGROUND

Poland has one of the highest cesarean birth (CB) rates in Europe. For this study, we used the Robson Ten-Group Classification System (TGCS) to analyze trends in the induction and CB rates in one hospital in Poland over a period of 11 years. We compare these trends with changes in National Legislative and Medical Guidelines introduced during this time that were aimed at lowering rates of unnecessary medical interventions.

METHODS

We conducted a retrospective study including all births after 24 weeks' gestation between 2010 and 2020 from one tertiary hospital (n = 66,716 births). After the deletion of records with missing data, 66,678 births were included in the analysis. All births were classified according to the Robson TGCS. The size, CB rate, and contribution of each group for every year were calculated. Linear regression analyses were used to analyze trends over time.

RESULTS

The total CB rate varied from 29.6% to 33.0% during the study period, with a linear increase of 0.045 percentage points annually (R2  = 0.021; F(1) = 0.189; p = 0.674). This study was considerably lower than the total CB rate for Poland, which rose from 33.9% in 2010 to 45.1% in 2020, increasing at a rate of 1.13 percentage points per year (R2  = 0.93; F(1) = 61.88; p < 0.001). Induction rates among both nulliparous (R1 + R2) and multiparous (R3 + R4) women at term also increased. Study groups R5 (previous cesarean birth), R2 (nulliparous in induced or prelabor cesarean delivery), and R1 (nulliparous women at term with single cephalic pregnancy in spontaneous labor) were the highest contributors to the overall CB rate. The greatest decrease in the CB rate was detected in group R5b (more than one previous CB). None of the groups showed statistically significant increases in CB rates over the study period.

CONCLUSIONS

The CB rate in the hospital where the study was conducted was considerably lower than the total CB rate in Poland. When compared with countries with similar CB rates, group R2b (women with nulliparous, prelabor cesarean birth) in our study was considerably larger. More comparisons across different hospital settings in Poland are needed. However, as hospitals are not encouraged to routinely collect the data needed to construct TGCS, such comparisons are very difficult to conduct.

Evidence of Placental Aging in Late SGA, Fetal Growth Restriction and Stillbirth-A Systematic Review

During pregnancy, the placenta undergoes a natural aging process, which is considered normal. However, it has been hypothesized that an abnormally accelerated and premature aging of the placenta may contribute to placenta-related health issues. Placental senescence has been linked to several obstetric complications, including abnormal fetal growth, preeclampsia, preterm birth, and stillbirth, with stillbirth being the most challenging. A systematic search was conducted on Pubmed, Embase, and Scopus databases. Twenty-two full-text articles were identified for the final synthesis. Of these, 15 presented original research and 7 presented narrative reviews. There is a paucity of evidence in the literature on the role of placental aging in late small for gestational age (SGA), fetal growth restriction (FGR), and stillbirth. For future research, guidelines for both planning and reporting research must be implemented. The inclusion criteria should include clear differentiation between early and late SGA and FGR. As for stillbirths, only those with no other known cause of stillbirth should be included in the studies. This means excluding stillbirths due to congenital defects, infections, placental abruption, and maternal conditions affecting feto-maternal hemodynamics.

The Experience of Women Giving Birth after Cesarean Section-A Longitudinal Observational Study

Natural childbirth after a previous cesarean section is a debated issue despite scientific research and international recommendations. This study aimed to examine the experiences of women giving birth after a previous cesarean section, their preferences, and changes in attitudes towards childbirth after labor. This longitudinal study involved 288 pregnant women who had a previous cesarean section and completed a web-based questionnaire before and after labor, including information about their obstetric history, birth beliefs, and preferred mode of delivery. Among women who preferred a vaginal birth, nearly 80% tried it and 49.78% finished delivery by this mode. Among women declaring a preference for an elective cesarean section, 30% attempted a vaginal birth. Choosing a hospital where staff supported their decision (regardless of the decision) was the most helpful factor in preparing for labor after a cesarean section (63.19%). Women's birth preferences changed after labor, with women who had a vaginal birth after a cesarean section preferring this mode of delivery in their next pregnancy (89.34%). The mode of birth did not always follow the women's preferences, with some women who preferred a natural childbirth undergoing an elective cesarean section for medical reasons. A variety of changes were noticeable among women giving birth after a cesarean section, with a large proportion preferring natural birth in their next pregnancy. Hospitals should support women's birth preferences after a cesarean section (if medically appropriate), providing comprehensive counseling, resources, and emotional support to ensure informed decisions and positive birth experiences.

Molecular Pathways of Altered Brain Development in Fetuses Exposed to Hypoxia

Perinatal hypoxia is a major cause of neurodevelopmental impairment and subsequent motor and cognitive dysfunctions; it is associated with fetal growth restriction and uteroplacental dysfunction during pregnancy. This review aims to present the current knowledge on brain development resulting from perinatal asphyxia, including the causes, symptoms, and means of predicting the degree of brain damage. Furthermore, this review discusses the specificity of brain development in the growth-restricted fetus and how it is replicated and studied in animal models. Finally, this review aims at identifying the least understood and missing molecular pathways of abnormal brain development, especially with respect to potential treatment intervention.

Anxiety and depressive symptoms in pregnant women during the COVID-19 pandemic in the Czech Republic-Broader sociodemographic causes, connections and implications

INTRODUCTION

Our study (part of multicentric "MindCOVID") investigates risk factors for anxiety and depression among pregnant women during the COVID-19 pandemic in the Czech Republic.

MATERIAL AND METHODS

The study used a prospective cross-sectional design. Data was collected using an online self-administered questionnaire. Standardized scales, general anxiety disorder (GAD)-7 and patient health questionnaire (PHQ)-9 were administered online. Multivariate regression analysis was employed to evaluate the relationship between sociodemographic, medical and psychological variables.

RESULTS

The Czech sample included 1830 pregnant women. An increase of depressive and anxiety symptoms measured by PHQ-9 and GAD-7 in pregnant women during the COVID-19 pandemic was associated with unfavorable financial situation, low social and family support, psychological and medical problems before and during pregnancy and infertility treatment. Fear of being infected and adverse effect of COVID-19, feeling of burden related to restrictions during delivery and organization of delivery and feeling of burden related to finances were associated with worse anxiety and depressive symptoms.

CONCLUSIONS

Social and emotional support and lack of financial worries are protective factors against mood disorders in pregnant women in relation to COVID-19 pandemic. In addition, adequate information about organization of delivery and additional support from healthcare professionals during the delivery are needed. Our findings can be used for preventive interventions, given that repeated pandemics in the future are anticipated.

Emergency cerclage using double-level versus single-level suture in the management of cervical insufficiency (Cervical Occlusion double-level Stitch Application, ): study protocol for a multicentre, non-blinded, randomised controlled trial

INTRODUCTION

Cervical insufficiency accounts for 15% of recurrent pregnancy losses between 16 and 28 weeks of gestation. The aim of the study is to verify the effectiveness of emergency double-level cerclage with vaginal progesterone in cervical insufficiency treatment in terms of the prevention of preterm delivery before 34 weeks of gestation.

METHODS AND ANALYSIS

This trial is a multicentre, non-blinded, randomised study with 1:1 allocation ratio. The study is conducted at tertiary perinatal care departments in Poland. It will include patients with cervical insufficiency with the fetal membranes visible in the open cervical canal or protruding into the vagina between 16+0 and 23+6 weeks of pregnancy. They will be randomised into two arms: emergency single-level cerclage with vaginal progesterone or double-level cerclage with vaginal progesterone. All will be administered antibiotics and indomethacin. The primary outcome is the rate of deliveries below 34+0 weeks of gestation, while secondary outcomes include gestational age at delivery, neonatal outcomes, maternal outcomes according to the Core Outcome Set for Evaluation of Interventions to Prevent Preterm Birth and cerclage procedure complications. The planned number of participants according to the power analysis is 78.

ETHICS AND DISSEMINATION

The study protocol was written in accordance with the Standard Protocol Items: Recommendations for Interventional Trials statement. It was created according to the requirements of the Declaration of Helsinki for Medical Research involving Human Subject. Ethical approval was obtained from the Ethics Committee of the Centre of Postgraduate Medical Education (no. 1/2022). The study protocol was approved and published by ClinicalTrials.gov (posted on 24 February 2022). All participants gave a written informed consent. After completion of the study its results will be published in a peer-reviewed English language journal.

Epidural analgesia: effect on labor duration and delivery mode - a single-center cohort study

OBJECTIVES

Parturients in labor experiencing severe pain may develop several complications, which could be avoided using various forms of labor analgesia. Researchers hold divergent opinions about the effect of epidural analgesia (EA) on labor duration and delivery mode. This paper aims to establish if EA affects the duration of the 1st and the 2nd phase of labor and the percentage of emergency Cesarean sections (CS) and instrumental delivery.

MATERIAL AND METHODS

The patients in this cohort study were recruited at St. Sophia's Specialist Hospital in Warsaw, between 1/1/2020 and 6/1/2020. We used following inclusion criteria: patients aged 18-40 with singleton pregnancies and cephalic presentation of the fetus who gave live birth at a gestational age of 37-42 weeks to neonates with birthweight 2500-4250 g and received EA at the cervical dilation between three and six centimeters. The control group didn't receive anesthesia. We excluded planned CS and vaginal births after CS. Data analysis was performed for all parturients and separately for multiparas and nulliparas. Results Out of 2550 deliveries, we included 1052 patients - 443 participants with EA and 609 in the control group. Patients with epidural analgesia experienced longer labor 415 vs 255 min (p < 0.01), longer 1st and 2nd stage (p < 0.01). They had a lower risk of emergency CS (OR = 0.56) (p < 0.01) but were more likely to have instrumental delivery.

CONCLUSIONS

EA prolongs the first and the second stage of labor yet doesn't affect neonatal outcomes. Moreover, the risk of emergency CS in nulliparas with EA is three times lower.

Progesterone and Its Metabolites Play a Beneficial Role in Affect Regulation in the Female Brain

Premenstrual dysphoric disorder is a female affective disorder that is defined by mood symptoms. The condition is linked to unstable progesterone concentrations. Progestin supplementation is given in cases of threatened or recurrent miscarriage and for luteal phase support. Progesterone is essential for implantation, immune tolerance, and modulation of uterine contractility. For a long time, the administration of progestins was associated with an unfavorable impact on mood, leading to negative affect, and, therefore, was contraindicated in existing mood disorders. Establishing the role of the natural progesterone derivative allopregnanolone in advances in the treatment of postpartum depression has shed new light on the general pathophysiology of mood disorders. Allopregnanolone directly interacts with gamma-aminobutyric acid type A (GABA-A) receptors even at nanomolar concentrations and induces significant anti-depressant, anti-stress, sedative, and anxiolytic effects. Postpartum depression is caused by a rapid drop in hormones and can be instantly reversed by the administration of allopregnanolone. Premenstrual dysphoric disorder can also be considered to result from insufficient neuroactive steroid action due to low progesterone derivative concentration, unstable hormone levels, or decreased receptor sensitivity. The decrease in progesterone levels in perimenopause is also associated with affective symptoms and an exacerbation of some psychosomatic syndromes. Bioidentical progesterone supplementation encounters several obstacles, including limited absorption, first-pass effect, and rapid metabolism. Hence, non-bioidentical progestins with better bioavailability were widely applied. The paradoxical, unfavorable effect of progestins on mood can be explained by the fact that progestins suppress ovulation and disturb the endocrine function of the ovary in the luteal phase. Moreover, their distinct chemical structure prevents their metabolism to neuroactive, mood-improving derivatives. A new understanding of progesterone-related mood disorders can translate the study results from case series and observational studies to cohort studies, clinical trials, and novel, effective treatment protocols being developed.

Did everyone change their childbirth plans due to the COVID-19 pandemic? A web-based cross-sectional survey of Polish pregnant women

BACKGROUND AND AIM

With the worldwide outbreak of coronavirus, a significant impact has been observed on the functioning of healthcare systems and the process of childbirth. Women probably did not even have a choice to adjust their plans accordingly to the current situation. The aim of the study was to examine how the outbreak of the SARS CoV-2 pandemic state affected the decisions of pregnant women about their childbirth plan.

DESIGN

This cross-sectional study was performed using a web-based survey published on social media in Poland.

METHODS

The cross-sectional study was performed using web-based questionnaires. The study group included Polish women who changed their childbirth plans, compared to a group of women not sure about delivery plan change and those whose plans had not changed. The data were collected from 4 March 2020 to 2 May 2020, when the first rising count of new infections was observed in Poland and worldwide. Statistical analysis was performed using STATISTICA Software, Inc., 13.3 (2020).

RESULTS

Of 969 women who completed the questionnaire and were enrolled into the study, 57.2% had not changed their childbirth plans (group I), 28.4% had changed their plans (group II), and 14.4% of respondents answered "not sure" to this question (group III). The majority of women changed their birth plans during the pandemic because of the potential absence of their partner during labour (56% of women who had changed their plans and 48% of those whose answer was "I am not sure", p < .001). Another reason was the fear of separation from the child after delivery (33% of women who had changed their plans and 30% of those whose answer was "I am not sure", p < .001).

CONCLUSION

Restrictions due to the COVID-19 outbreak have influenced the childbirth plans of pregnant women. The changes were independent of women's vision of birth before the pandemic.

IMPACT

The restriction on births with accompanying person and the risk of separation from their infant after childbirth significantly influenced the decision-making process. As a result, some women were more likely to opt for a home birth with or even without medical assistance.

PATIENT OR PUBLIC CONTRIBUTION

The study participants were women who were pregnant at the time of completing the questionnaire, were over 18 years old and spoke Polish.

Atypical Preeclampsia before 20 Weeks of Gestation-A Systematic Review

This systematic review was conducted to gather evidence of preeclampsia occurring before the 20th week of gestation, additionally considering the role of PLGF and sFlt-1 in the development of the disease. In the three cases of preeclampsia before the 20th week of gestation presented in the authors' material, all pregnancies ended up with IUFD, and the SFlt-1/PLGF ratios were significantly elevated in all women. Eligible publications were identified with searches in the PubMed, Embase, Scopus, and Web of Science databases. No date or language restrictions were made. All original peer-reviewed scientific reports were included. A total of 30 publications were included in the final report, including case reports and case series. No other publication types regarding this issue were identified. In the literature, 34 cases of preeclampsia with onset occurring before the 20th week of gestation were identified, for a final total of 37 cases. Live births were reported in 5 cases (10.52%), and there were 9 intrauterine fetal demises (24.32%), and 23 terminations of pregnancy (62.16%). Preeclampsia before the 20th week of gestation is rare but can occur. We collected all available evidence regarding this phenomenon, with 37 cases reported worldwide. We call for large-scale cohort or register-based studies to establish revised definitions or develop new ones regarding the currently unrecognized very early onset preeclampsia.

Anxiety of pregnant women in time of catastrophic events, including COVID-19 pandemic: a systematic review and meta-analysis

PURPOSE

In March 2020, daily life was disrupted by the new virus SARS-CoV-2, which causes COVID-19. Pandemic-related prenatal anxiety could lead to depression, a risk factor for adverse pregnancy outcomes and abnormal neonatal development. This study aimed to investigate the impact of anxiety on the mental health of pregnant women exposed to catastrophic events as compared to those without such exposure.

MATERIALS AND METHODS

PubMed/MEDLINE, Web of Science, Cochrane Library, Scopus, and EMBASE were searched for relevant studies. This study compared the prevalence of anxiety among pregnant women during a catastrophic event.

RESULTS

Fifteen full texts were assessed for inclusion, with 3 included, 10 excluded for not meeting criteria, and 2 excluded for other reasons. The included studies were published before the current COVID-19 pandemic but included the SARS 2003 outbreak. During the current COVID-19 pandemic, 10 further studies were conducted, but they failed to meet the inclusion criteria. A meta-analysis of two studies using STAI revealed that women exposed to a catastrophic event had a higher mean STAI score of 1.82 points (95% CI: 0.47-3.18 points).

CONCLUSION

Women with complications during pregnancy should be assessed for anxiety independently from catastrophic events. During financial crises, environmental or other disasters, special attention should be given to women with low risk, normal pregnancies.

Prevalence and factors associated with postpartum pelvic girdle pain among women in Poland: a prospective, observational study

Background

Pelvic girdle pain (PGP) is a type of pregnancy-related lumbopelvic pain. This study aimed to examine the prevalence, severity, and factors associated with postpartum PGP in a selected group of postpartum women in Poland.

Methods

This was a prospective, observational study. In phase 1, 411 women were recruited 24–72 h postpartum. The prevalence of PGP was assessed by a physiotherapist using a series of dedicated tests. Pelvic floor muscle function and presence of diastasis recti were assessed via palpation examination. Age, education, parity, mode of delivery, infant body mass, body mass gain during pregnancy, the use of anesthesia during delivery and were recorded. In a phase 2, 6 weeks postpartum, the prevalence of PGP and its severity were assessed via a self-report.

Results

In phase 1 (shortly postpartum), PGP was diagnosed in 9% (n = 37) of women. In phase 2 (6 weeks postpartum), PGP was reported by 15.70% of women (n = 42). The univariable analyses showed a higher likelihood of PGP shortly postpartum in women who declared PGP during pregnancy (OR 14.67, 95% CI 4.43–48.61) and among women with abdominal midline doming (OR 2.05, 95% CI 1.04–4.06). The multivariable regression analysis showed significant associations in women with increased age (OR 1.12, 95% CI 1.01–1.21) and declaring PGP during pregnancy (OR 14.83, 95% CI 4.34–48.72).

Conclusion

Although the prevalence of postpartum PGP among women in Poland is lower than reported in other countries, it is experienced by almost every tenth women shortly postpartum and every sixth can report similar symptoms 6 weeks later. Age, PGP during pregnancy and abdominal midline doming were associated with experiencing PGP shortly postpartum.

Intrapartum cardiotocography in pregnancies with and without fetal CHD

OBJECTIVES

Congenital heart defects (CHD) are the most common inherited abnormalities. Intrapartum cardiotocography (CTG) is still considered a "gold standard" during labor. However, there is a lack of evidence regarding the interpretation of intrapartum CTG in fetuses with CHD. Therefore, the study aimed to compare intrapartum CTG in normal fetuses and fetuses with CHD and describe the association between CTG and neonatal outcomes.

METHODS

The present study is a retrospective analysis of the CTG of 395 fetuses. There were three study groups: Group 1: 185 pregnancies with a prenatal diagnosis of CHD, Group 2: 132 high-risk pregnancies without CHD, and Group 3: 78 low-risk pregnancies without CHD.

RESULTS

Abnormal CTG was present statistically OR=3.4 (95%CI: 1.61-6.95) more often in Group 1. The rate of the emergency CS was higher in this group OR=3 (95%CI: 1.3-3.1). Fetuses with CHD and abnormal CTG were more often scored ≤7 Apgar, with no difference in acidemia. The multivariate regression model for Group 1 does not show clinical differences between Apgar scores or CTG assessment in neonatal acidemia prediction.

CONCLUSIONS

CTG in fetuses with CHD should be interpreted individually according to the type of CHD and conduction abnormalities. Observed abnormalities in CTG are associated with the fetal heart defect itself. Preterm delivery and rapid cesarean delivery lead to a higher rate of neonatal complications. Health practitioners should consider this fact during decision-making regarding delivery in cases complicated with fetal cardiac problems.

Risk factors for anxiety and depression among pregnant women during the COVID-19 pandemic: Results of a web-based multinational cross-sectional study

OBJECTIVE

To assess risk factors for anxiety and depression among pregnant women during the COVID-19 pandemic using Mind-COVID, a prospective cross-sectional study that compares outcomes in middle-income economies and high-income economies.

METHODS

A total of 7102 pregnant women from 12 high-income economies and nine middle-income economies were included. The web-based survey used two standardized instruments, General Anxiety Disorder-7 (GAD-7) and Patient Health Questionnaire-9 (PHQ-9).

RESULT

Pregnant women in high-income economies reported higher PHQ-9 (0.18 standard deviation [SD], P < 0.001) and GAD-7 (0.08 SD, P = 0.005) scores than those living in middle-income economies. Multivariate regression analysis showed that increasing PHQ-9 and GAD-7 scales were associated with mental health problems during pregnancy and the need for psychiatric treatment before pregnancy. PHQ-9 was associated with a feeling of burden related to restrictions in social distancing, and access to leisure activities. GAD-7 scores were associated with a pregnancy-related complication, fear of adverse outcomes in children related to COVID-19, and feeling of burden related to finances.

CONCLUSIONS

According to this study, the imposed public health measures and hospital restrictions have left pregnant women more vulnerable during these difficult times. Adequate partner and family support during pregnancy and childbirth can be one of the most important protective factors against anxiety and depression, regardless of national economic status.

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.

Association Among Pelvic Girdle Pain, Diastasis Recti Abdominis, Pubic Symphysis Width, and Pain Catastrophizing: A Matched Case-Control Study

OBJECTIVE

Pregnancy-related pelvic girdle pain (PGP) may persist or occur postpartum and negatively affects women's lives. There is uncertainty regarding the association between the structures of the bony pelvis, diastasis recti abdominis (DRA), pain processing, and PGP and to what extent these factors should be considered during physical therapy. This study aimed to evaluate the differences between women with and without PGP shortly after delivery regarding the separation of a pubic symphysis, DRA, and pain catastrophizing.

METHODS

Women diagnosed with PGP 24 to 72 hours after vaginal delivery were matched to pain-free controls according to age and parity. Ultrasound evaluations of diastasis recti (interrecti distance [IRD]) during rest and curl-up task and pubic symphysis (interpubic width) were performed. The Pain Catastrophizing Scale was used to assess the level of catastrophizing. A special Cox regression model was used to fit a conditional logistic regression for a 1:2 matched case-control study.

RESULTS

Thirty-five women with clinically diagnosed PGP and 70 matched controls were included in the study. The PGP group had a significantly higher pre-pregnancy body mass index than the control group. After adjusting for body mass index in multiple conditional logistic regression, the interpubic distance (odds ratio = 1.64; 95% CI = 1.22 to 2.20) and IRD during curl-up (odds ratio = 2.01; 95% CI = 1.08 to 3.74) were significantly associated with PGP. Pain catastrophizing and IRD at rest were not associated with PGP in univariable or multivariable analysis.

CONCLUSIONS

Pain catastrophizing is similar for women with and without PGP early postpartum. However, the degree of the pubic symphysis and rectus abdominis separation during the curl-up task are positively associated with PGP shortly after delivery.

IMPACT

This study indicates that a reconsideration of the way we look at DRA is warranted. The development of a more comprehensive assessment including objective measurements and a biopsychosocial understanding is needed to inform directions for further postpartum physical therapy.

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.

The Polish Society of Gynecologists and Obstetricians Guideline for the diagnostic assessment and management of multiple-gestation pregnancy complicated by fetal growth restriction

The aim of the Guideline is to unify the diagnostic-therapeutic management of multiple-gestation pregnancies complicated by fetal growth restriction in at least one fetus.

Oxytocin administration for induction and augmentation of labour in polish maternity units - an observational study

BACKGROUND

There is not enough data regarding practices and protocols on the dose of oxytocin administrated to women during labour. Empirical evidence indicates that compliance with the guidelines improves the quality of healthcare and reduces adverse effects. The study aimed to evaluate practices of oxytocin provision for labour induction and augmentation in two maternity units in Poland.

METHODS

The article presents a prospective observational study. Data from 545 (n = 545) labours was collected in two maternity units. First, the total dose (the total amount of oxytocin provided from the beginning in the labour ward until delivery including the III and IV stage of labour) and cumulative dose of oxytocin (the amount of oxytocin given until the birth of the neonate) administered to women during labour was calculated. Then, the relationship between the cumulative dose of oxytocin and short term perinatal outcomes (mode of delivery, use of epidural anaesthesia, Apgar scores, birth weight and postpartum blood loss) was analysed. Finally, the compliance of oxytocin supply during labour with national guidelines in the following five criteria: medium, start dose, escalation rate, interval, the continuation of infusion after established labour was examined.

RESULTS

The average cumulative dose of oxytocin administrated to women before birth was 4402 mU following labour induction and 2366 mU following labour augmentation. The actual administration of oxytocin deviated both from the unit and national guidelines in 93.6% of all observed labours (mainly because of continuation of infusion after established labour). We found no statistically significant correlation between the cumulative dose of oxytocin administered and mode of delivery, immediate postpartum blood loss or Apgar scores. There was no observed effect of cumulative dose oxytocin on short-term perinatal outcomes. The two units participating in the study had similar protocols and did not differ significantly in terms of total oxytocin dose, rates of induction and augmentation - the only observed difference was the mode of delivery.

CONCLUSIONS

The study showed no effect of the mean cumulative oxytocin dose on short-term perinatal outcomes and high rate of non-compliance of the practice of oxytocin administration for labour induction and augmentation with the national recommendations. Cooperation between different professional groups of maternity care providers should be considered in building national guidelines for maternity care.. Further studies investigating possible long-term effects of the meant cumulative dose of oxytocin and the reasons for non-compliance of practice with guidelines should be carried out.

Uterine Artery Doppler Reference Ranges in a Twin Caucasian Population Followed Longitudinally From 17 to 37 Weeks Gestation Compared to That of Singletons

OBJECTIVES

The primary aim was to measure uterine artery (UtA) indices in twin pregnancies of Polish Caucasian women and compare it with a previously published study by Geipel et al for DC twins (2011). The secondary aim was to find differences in UtA indices in MC, DC twins, and singletons.

METHODS

A prospective longitudinal evaluation of UtA Doppler indices in 1462 examinations of twins and 5766 examinations of singletons between 17 and 37 gestational age (GA). Pulsatility index (PI) and resistance index (RI) were calculated.

RESULTS

UtA PI and RI are lower in the twins than singletons but the analyzed mean values throughout gestation are higher than the study presented by Geipel et al. Obtained curves for DC twins and singletons had the same form as Geipel's curves. In MC twins, curves are flatter and characterized by lower differences throughout pregnancy than Geipel's curves for DC twins. They tend to be more similar about 32 weeks of gestations, resulting from different placenta structure in MC than DC twin pregnancies.

CONCLUSIONS

UtA Doppler indices in twin pregnancies are lower than in singletons. Obtained data have higher values for twins than reference charts proposed by Geipel's for dichorionic twins. We observed some differences between monochorionic and dichorionic twins' curves throughout pregnancy, but they were not significant.

Women's views of birth after cesarean section

BACKGROUND

Vaginal birth is a safe mode of childbirth for the majority of women after cesarean section (CS). However, data show that women who have undergone a CS are more likely to have an elective CS (ECS) than a vaginal birth after CS (VBAC) in many areas of the world.

AIM

This study aimed to review the literature about women's mode of birth preferences and attitudes and the underlying reasons for, and factors associated with, their preferences.

METHODS

This is narrative literature review. PubMed/MEDLINE and Scopus databases were searched, limiting the results to non-interventional studies published between 1990 and 2020. Twenty-one articles were included in the analysis.

RESULTS

The review found 34 different factors that influence women's preferences. Five factors influenced both VBAC and ECS preference, depending on the study. The most common factors having a dualistic effect on preference were: medical staff recommendation, doctor's opinion, and fear of pain. The most common factors were: desire to experience natural childbirth, faster/easier recovery, support from doctor's, and midwife's opinion. Among the factors influencing the preference for ECS, two were particularly prominent: predictability, controllability and comfortability of CS and the belief that CS is safer for the baby and/or mother.

CONCLUSIONS

Our review showed that there are a variety of factors that influence women's preference for the mode of delivery after CS. Some of these have a dualistic effect according to the study. The key to making an informed decision regarding the mode of delivery is communication with medical professionals.

Effect of Maternal and Fetal Characteristics in Feto-Placental Doppler and Impact of Using Adjusted Standards in the Definition of Fetal Growth Restriction at Term

INTRODUCTION

This study aimed to determine the effect and clinical impact of physiological characteristics on the 95th/5th centile of the umbilical artery (UA) Doppler and the cerebroplacental ratio (CPR), at 36+ weeks.

METHODS

From the multicenter randomized trial "Ratio37," we selected 4,505 low-risk pregnant women between June 2016 and January 2020. We registered physiological characteristics and the pulsatility indexes (PI) of the UA and middle cerebral artery (36-39 weeks). The 95th/5th centile of the UA PI and CPR was modeled by quantile regression. To evaluate the clinical impact of adjusting Doppler, we retrospectively applied gestational age (GA) and fully adjusted standards to 682 small for gestational age (SGA)-suspected fetuses (37 weeks) from a cohort of consecutive patients obtained between January 2010 and January 2020.

RESULTS

Several physiological characteristics significantly influenced the 95th/5th centile of the UA and CPR PI. The fully adjusted 95th centile of the UA was higher, and the 5th centile of the CPR was lower than GA-only-adjusted standards. Of the 682 SGA fetuses, 150 (22%) were classified as late fetal growth restricted only by GA and 112 (16.4%) when we adjusted Doppler. These 38 fetuses had similar perinatal outcome than the SGA group.

DISCUSSION

The 95th/5th centile of the UA and CPR PI is significantly influenced by physiological characteristics. Adjusting Doppler standards could differentiate better between FGR and SGA.

Evaluation of indications for amniocentesis in cases of normal fetal ultrasound results

OBJECTIVES

The objective of this study was to analyze indications for amniocentesis in cases of patients with normal fetal ultrasound results between 11+0 and 13+6 weeks of gestation.

MATERIAL AND METHODS

The results of first-trimester screening tests performed between 2014 and 2018 on 6,863 patients of the Prenatal Testing Outpatient Clinic at the Clinical Department of Obstetrics and Gynecology, Pomeranian Medical University, Szczecin, Poland, were analyzed. The inclusion criteria were a singleton pregnancy and normal results of fetal ultrasound between 11+0- and 13+6-weeks' gestation. Depending on the calculated risk of fetal trisomy 21, the patients were divided into three groups (group A = RS > 1:300, group B = RS 1:300 - 1:999, group C = RS ≤ 1:1000). Subsequently, values such as PAPP-A and fβ-hCG protein levels and maternal age were analyzed for each of the groups.

RESULTS

The patients, 6,310 (91.94%) met the inclusion criteria. A high risk of fetal trisomy 21 was identified for 514 women (8.15%). Group B had 733 (11.62%) and group C 5,063 (80.23%) patients. In group A, an fβ-hCG level of ≥ 2.000 MoM was shown for 50.97% of the women. A PAPP-A level ranging from 0.001 to 0.499 MoM was observed for 38.72% of group A patients. The mean maternal age in groups A, B and C was 36.45, 36.08 and 31.64 years, respectively.

CONCLUSIONS

In the first-trimester, patients with normal ultrasound results obtained during prenatal screening tests, the main cause of an increased risk of trisomy 21 was elevated PAPP-A and fβ-hCG concentrations. According to this paper's authors, in these cases extension of diagnosis to include other gestational complications, e.g. preeclampsia, should be considered.

Is growth restriction in twin pregnancies a double challenge? - A narrative review

Background

Foetal growth restriction (FGR) complicates about 25–47% of twin pregnancies. One or both foetuses can be restricted. Pregnancies with discordant growth of foetuses are associated with a sevenfold increased risk of neonatal morbidity.

Materials and methods

This is a narrative or traditional literature review. A literature search was performed to present a comprehensive, critical and objective analysis of the current knowledge on growth restriction in twin pregnancies.

Results

The definitions of FGR in twin pregnancies and selective FGR (sFGR) differ between international societies. In 2019, the Delphi procedure aimed to unify the definitions of sFGR in twin pregnancies. Several growth charts for twins have been published. However, most societies recommend singleton growth charts as better in detecting hypoxic complications of FGR in twin pregnancies. Discordant growth in twins results from placental insufficiency, congenital anomalies, chromosomal aberrations and TORCH infections.

Conclusions

Definitions and management of sFGR depend on chorionicity. The management aims to protect the properly growing foetus from ischemic complications or in utero death. In most cases, expectant management, strict surveillance and preterm labour are the methods of choice. Due to the co-existence of properly growing and small foetuses in one uterus, determining the appropriate time for delivery is challenging. In the case of preterm labour, even late preterm, antenatal corticosteroid therapy (ACT) in FGR twin pregnancies is beneficial because it decreases neonatal morbidity.

Growth Abnormalities as a Risk Factor of Adverse Neonatal Outcome in Hypertensive Pregnancies-A Single-Center Retrospective Cohort Study

(1) Background: Hypertensive disorders of pregnancy (HDP) include gestational hypertension (GH), chronic hypertension (CH), preeclampsia (PE), and preeclampsia superimposed on chronic hypertension (CH with PE). HDP is associated with several short and long-term perinatal and neonatal complications, such as newborn growth restriction and death. This study aimed to establish the association between HDP, newborn growth abnormalities, and neonatal outcome. (2) Methods: This is a single-center retrospective cohort study of 63651 singleton deliveries. (3) Results: Univariate analysis showed a significantly increased risk of intrauterine and neonatal death associated with maternal hypertension and growth disorders. There were differences between growth charts used, with the highest risk of stillbirth for SGA defined by the Intergrowth chart (OR 17.2) and neonatal death for newborn growth restriction (NGR) based on Intergrowth (OR 19.1). Multivariate analysis showed that NGR is a stronger risk factor of neonatal death than SGA only. (4) Conclusions: HDP is significantly associated with growth abnormalities and is an independent risk factor of adverse outcomes. The presence of newborn growth restriction is strongly associated with the risk of neonatal death. The choice of growth chart has a substantial effect on the percentage of diagnosis of SGA and NGR.

Compliance with gestational weight gain recommendations in a cross-sectional study of term pregnancies - how far reality falls from the standard?

OBJECTIVES

During pregnancy, two aspects are critical in the context of adverse perinatal outcomes (APO): preconception obesity and gestational weight gain. This study aimed to assess compliance with the 2009 IOM guidelines, compare GWG with and without correcting for gestation duration, and observe the relationship between pre-pregnancy BMI and GWG and neonatal birth weight.

MATERIAL AND METHODS

This is a cross-sectional study conducted from 2015-2018 at the St. Sophia's Specialist Hospital in Warsaw, Poland. Self-reported pre-pregnancy and predelivery weight were collected.

RESULTS

The presented data set amounts to 7820 records. Analysis of weight gain compliance with IOM recommendations showed that only 41-44% (depending on the calculation method) of women had weight gain in accordance with IOM guidelines (22-23% - below; 33-37% - above). Overweight and obese women with diabetes are more likely to comply with IOM than women without diabetes. In contrast, women with normal-weight and underweight with diabetes are less likely to achieve IOM weight gain in pregnancy than women without diabetes. Women who have GWG below recommendations significantly more often gave birth to SGA neonates, and women who exceeded GWG standards significantly more often gave birth to LGA neonates.

CONCLUSIONS

Less than half of women had GWG within the recommended norms. Statistically significant differences were found in methods of calculation of GWG, but it was not found clinically significant. Correction for pregnancy duration when calculating GWG reclassifies two percent of patients. We underestimate the risk of crossing the line between overweight and obesity during pregnancy.

Molecular Pathways of Cellular Senescence and Placental Aging in Late Fetal Growth Restriction and Stillbirth

Abnormally accelerated, premature placental senescence plays a crucial role in the genesis of pregnancy pathologies. Abnormal growth in the third trimester can present as small for gestational age fetuses or fetal growth restriction. One differs from the other by the presence of signs of placental insufficiency and the risk of stillbirth. The majority of stillbirths occur in normally grown fetuses and are classified as "unexplained", which often leads to conclusions that they were unpreventable. The main characteristic of aging is a gradual decline in the function of cells, tissues, and organs. These changes result in the accumulation of senescent cells in mitotic tissues. These cells begin the aging process that disrupts tissues' normal functions by affecting neighboring cells, degrading the extracellular matrix, and reducing tissues' regeneration capacity. Different degrees of abnormal placentation result in the severity of fetal growth restriction and its sequelae, including fetal death. This review aims to present the current knowledge and identify future research directions to understand better placental aging in late fetal growth restriction and unexplained stillbirth. We hypothesized that the final diagnosis of placental insufficiency can be made only using markers of placental senescence.

Fetal Growth Diagnosis and Management among Perinatal Medical Professionals: A Survey of Practice and Literature Review

INTRODUCTION

This paper aimed to assess the knowledge of healthcare professionals (obstetric and gynecology residents, specialists, and midwives) in the field of perinatal medicine regarding fetal growth diagnosis and management.

METHODS

A questionnaire was created consisting of a set of questions regarding demographic data, methods of growth assessment, and management. It was a handout survey. The results were analyzed with the use of descriptive statistics and χ2 analysis using the program Statistica.

RESULTS

190 medical professionals have participated in the questionnaire. 86.3% of respondents agreed that pregnancy dating should be modified based on first-trimester ultrasound. 90.9% agreed that III trimester ultrasound has a ±15% margin of error. When asked which growth charts are best fit for assessing growth in a studied population, 10.7% marked standard, 37.4% reference, 26.2% customized, and 26.2% did not know the difference between the three choices. 60.3% stated that they use a growth chart to assess growth and qualify fetuses for monitoring. 70.2% used the 10th centile as a cutoff, 20.1% 5th centile, and 9.7% 3rd centile. Only 40.9% would diagnose fetal growth restriction based on fetal weight only. 28.7% using the 10th centile cutoff, 16.1% 5th centile, and 54.0% 3rd centile. Only a quarter of the respondents were able to name the growth chart or tool that they use for assessment. The most common responses were Yudkin, Hadlock, and online calculators of Fetal Medicina Barcelona and the Fetal Medicine Foundation.

DISCUSSION

A lot of confusion is observed primarily in the aspect of cutoff values for identification, subsequent monitoring, and management of fetal growth restriction. There is a need for extensive training and education in this field and uniform national recommendations.

Woman's Needs and Satisfaction Regarding the Communication with Doctors and Midwives during Labour, Delivery and Early Postpartum

The study aimed to identify the difference in communication needs of women giving birth and women during early postpartum. An additional goal includes the analysis of the experience and communication needs through the context of a woman's approach to childbirth. The study is a cross-sectional, self-report survey; 521 women between 5 and 10 days after birth participated in the study. Women perceived information provided by the medical staff as the most helpful aspect of verbal communication both during labour and early postpartum. Maintaining eye contact with the medical staff was perceived as the most helpful aspect of non-verbal communication. Women were more satisfied with communication during labour and birth than in the maternity ward and those after non-instrumental childbirth were more satisfied with communication compared to the instrumental birth group. Women perceiving childbirth as the natural, physiological process considered verbal and non-verbal communication during and after childbirth as less helpful than women perceiving birth as more risky and requiring interventions. The results of the study emphasize the importance of verbal and non-verbal communication during birth and early postpartum and at the same time different communication needs during these two time points. It also showed that women who perceive labour as a physiological process seem to be less dependent on the communication with the medical staff than women who accept medical interventions during labour and birth as necessary.

Fetal Growth Acceleration-Current Approach to the Big Baby Issue

Background and Objectives: Fetal overgrowth is related to many perinatal complications, including stillbirth, cesarean section, maternal and neonatal injuries, and shoulder dystocia. It is related to maternal diabetes, obesity, and gestational weight gain but also happens in low-risk pregnancies. There is ongoing discussion regarding definitions, methods of detection, and classification. The method used for detection is crucial as it draws a line between those at risk and low-risk popula-tions. Materials and Methods: For this narrative review, relevant evidence was identified through PubMed search with one of the general terms (macrosomia, large-for-gestational-age) combined with the outcome of interest. Results: This review summarizes evidence on the relation of fetal overgrowth with stillbirth, cesarean sections, shoulder dystocia, anal sphincter injury, and hem-orrhage. Customized growth charts help to detect mothers and fetuses at risk of those complica-tions. Relations between fetal overgrowth and diabetes, maternal weight, and gestational weight gain were investigated. Conclusions: a substantial proportion of complications are an effect of the fetus growing above its potential and should be recognized as a new dangerous condition of Fetal Growth Acceleration.

Large-for-gestational-age or macrosomia as a classifier for risk of adverse perinatal outcome: a retrospective cross-sectional study

OBJECTIVE

Small for gestational age (SGA) fetuses and neonates are of great interest, while those who are too big are much less studied. The aim was to analyze the classifiers described by ACOG "Fetal macrosomia" practice bulletin as predictors of adverse perinatal outcomes for overgrown fetuses and their mothers.

MATERIALS

From a database of 53,586 singleton term births, appropriate-for-gestational-age (AGA), large for gestational age (LGA), and macrosomic deliveries were selected. AGA served as a control. The crude and adjusted odds ratios (aORs) were calculated for large-for-gestational-age >90th centile, and macrosomia >4000 g, >4250 g, and >4500 g. Patients with and without diabetes were analyzed separately.

RESULTS

Macrosomia >4000 g performed poorer than other classifiers. LGA performed comparably to other definitions of macrosomia. Diabetes carries a severe risk of complications for overgrown neonates, but those non-diabetic also have increased risk.

CONCLUSIONS

Definition of macrosomia as weight >4000 g should be reconsidered. LGA >90th centile should be used as a definition of fetal overgrowth along with other definitions of macrosomia.

A unique case of diagnosis of a heterotopic pregnancy at 26 weeks - case report and literature review

BACKGROUND

Heterotopic pregnancy (HP) is a rare condition when at least two pregnancies are present simultaneously at different implantation sites and only one located in the uterine cavity. The majority of cases are diagnosed in the first trimester.

CASE PRESENTATION

We present a unique case of HP diagnosed at 26 weeks of spontaneous pregnancy in a patient without any relevant risk factors. We performed an extensive review of HP cases from MEDLINE (PUBMED) published in English between 2005-2019 to prove this case's uniqueness. A 24-year-old woman presented because of threatened preterm birth. Despite treatment, pain aggravated, without progression of labor. An emergency ultrasound exam revealed free fluid in the abdominal cavity. Suspicion of active bleeding prompted the medical team to perform an exploratory laparotomy. The surgery team found a ruptured heterotopic pregnancy. This was an unexpected cause of nontraumatic hemoperitoneum at such advanced gestational age. The postoperative period was uneventful, and the intrauterine pregnancy continued to term. The final review included 86 out of 124 records. A total number of 509 cases were identified, but not all of them had complete data. The maximum reported gestational age at the time of diagnosis was 16 weeks of pregnancy, while our case became symptomatic and was diagnosed at 26 weeks of pregnancy.

CONCLUSIONS

Regardless of pregnancy age, HP can be a cause of hemoperitoneum, and it should be included in the differential diagnosis of acute abdomen in the second trimester.

What are the Critical Elements of Satisfaction and Experience in Labor and Childbirth-A Cross-Sectional Study

The labor experience and satisfaction with childbirth are affected by the care provided (external factors) and individual variables (internal factors). In this paper, we present a descriptive analysis that aims to indicate the strongest correlates of birth experience among a wide range of indicators. The study is a prospective, cross-sectional, self-report survey. It includes the experiences of women giving birth in public and private hospitals in Poland. The two main variables were birth experience and satisfaction with care. The analysis consists of three parts: data pre-processing and initial analysis, explorative investigation, and regression analysis. Among the 15 variables with the highest predictive value regarding birth experience were being informed by the medical personnel, communication, and birth environment. The most significant variables among 15 variables, with the highest predictive value regarding care, were those concerning support, information, and respectful care. The strongest predictor for both, birth experience and satisfaction with care, is the sense of information, with logit coefficients of 0.745 and 1.143, respectively, for birth experience and satisfaction (0.367 and 0.346 for standardized OLS coefficient). The findings demonstrate that by using explanatory variables, one can predict a woman’s description of her satisfaction with perinatal care received in the hospital. On the other hand, they do not have such a significant and robust influence on the birth experience examined by the variables. For both the birth experience and satisfaction with care, the sense of being informed is the highest predictor.

Application of artificial intelligence in screening for adverse perinatal outcomes: A protocol for systematic review

The article presents a systematic review protocol. The aim of the study is an assessment of current studies regarding the application of artificial intelligence and neural networks in the screening for adverse perinatal outcomes. We intend to compare the reported efficacy of these methods to improve pregnancy care and outcomes. There are more and more studies that describe the role of machine learning in facilitating the diagnosis of adverse perinatal outcomes, like gestational diabetes or pregnancy hypertension. A systematic review of available literature seems to be crucial to compare the known efficacy and application. Publication of a systematic review in this category would improve the value of future studies. The studies reporting on artificial intelligence application will have a major impact on future prenatal practice.

Monoamniotic twins pregnancy complicated by a fetal congenital heart defect – a challenge for perinatal decisions

Objectives

To analyze pregnancy management and postnatal follow-up in monochorionic monoamniotic (MCMA) pregnancies complicated by a congenital heart defect (CHD) in one twin and to compare the results with current recommendations concerning time and mode of delivery in MCMA pregnancies.

Cases presentation

Perinatal medical records of five pairs of monoamniotic twins referred to Fetal Cardiology Department were analyzed. 5 out of 23 MCMA pregnancies (21.7%) were complicated by CHD in one fetus. Cesarean section (CS) was performed between 32 and 35 weeks of gestation (WoG). 9 out of 10 neonates had respiratory failure, including all patients with CHD. Twins without congenital abnormalities spent median 21 days (range 10–40 days) in neonatal units. Patients with CHD were transferred to cardiology departments on average 6th day of life. All were operated on later than term-born neonates, 4 out of 5 required stage surgery and their median stay in the hospital was 75 days (range 48–106 days).

Conclusions

According to current recommendations, delivery in MCMA pregnancies should be scheduled at 32–34 weeks. In cases complicated by CHD in one twin, such early delivery complicates surgical treatment and may affect the final outcome. Low body weight and respiratory disorders increase the risk of complications in the perioperative period and prolong hospitalization.

Risk factors for anxiety and depression among pregnant women during the COVID-19 pandemic: A web-based cross-sectional survey

INTRODUCTION

The article presents a protocol of a cross-sectional study of mental health of pregnant women in relation to the coronavirus disease 19 (COVID-19) pandemic. The primary aim is to compare differences in anxiety and depression scores of pregnant women between countries affected by the COVID-19 pandemic. The secondary aim is to assess demographic, economic, and social aspects affecting maternal anxiety and depression scores among pregnant women worldwide in the time of the COVID-19 pandemic. Finally, we will be able to compare differences in perception of the different aspects of the COVID-19 pandemic (social distancing, restrictions related to delivery) between countries and according to the epidemic status (number of infected patients, number of reported deaths). The comparisons will also be done according to the COVID-19 status of the participants.

METHODS AND ANALYSIS

It is a web-based anonymous survey of pregnant women living in countries affected by the COVID-19 pandemic. The survey is comprised of 3 sections:Web-based recruitment for health research has proven to be cost-effective and efficient. At current times with the COVID-19 pandemic, limited resources and social distancing restrictions, performing a mental health study involving pregnant women on a large international scale cannot be safely conducted without involving social-media.The fears of pregnant women fall into 3 categories: the medical condition, the economic status and the organization of daily activity.The study has received approval of the medical ethics committee and has been registered on Clinicaltrials.gov. Results will be published in peer-reviewed journals and made public through all available media.

The role of lymphocytes in fetal development and recurrent pregnancy loss

Fetal survival and development is supported by the maternal immune system. Questions regarding those mechanisms have risen from development of transplantation medicine and observation of graft rejection. Initial theories of anatomic division, fetal immune immaturity and maternal immune system inertia were found incorrect. Rejection of fetal "semi-allograft" by maternal immune system could result in pregnancy loss. Two pregnancy losses of any etiology are considered recurrent and effort should be made to name the probable cause. Immune causes of pregnancy loss are probably multifactorial, thus difficult to research and implement findings in clinical practice. Although a full understating of pregnancy loss is not established, new therapies are being developed. This review summarizes the role of lymphocytes in pregnancy develop- ment, presents data from studies on recurrent pregnancy loss patients, evidence of new therapies and ESHRE guidelines regarding immunologic investigations.
