This article, titled "EP17.25: The outcomes of fetal intraumbilical vein varix: one comparative study," examines the perinatal outcomes of fetal intra-abdominal umbilical vein varix (FIUVV), a rare malformation characterized by a dilated umbilical vein. The study compares the outcomes of pregnancies with FIUVV to those of a control group without the condition. The results show that FIUVV is associated with growth restriction and congenital anomalies, but the overall perinatal outcome is similar to that of the normal fetal population. The study recommends targeted anomaly scans and growth assessments for pregnancies with FIUVV and does not support labor induction before 39 weeks. [Extracted from the article]

This article compares the perinatal outcomes of active management versus routine management in cases of true knot of the umbilical cord (TKUC). The study included singletons born beyond 22 6/7 weeks with TKUC and compared outcomes between those with prenatally detected TKUC receiving active management and those with postnatally detected TKUC receiving routine management. The results showed that active management did not confer a proven benefit over routine management, and in fact, active management was associated with higher rates of cesarean section, prematurity, induced prematurity, and neonatal intensive care unit admissions. The authors recommend avoiding labor induction before 37 weeks. [Extracted from the article]

This article presents a case study of a 38-year-old pregnant patient who presented with symptoms of headache, phosphenes, and bilateral lower limb edema. The patient had high blood pressure and ultrasound examinations revealed fetal growth restriction, oligohydramnios, and avascular areas within the placenta. Due to the high risk of maternal deterioration, placenta abruption, and stillbirth, the patient underwent an emergency Caesarean section and delivered a live male newborn. Gross anatomy of the placenta showed avascular areas suggestive of necrosis, which is consistent with the diagnosis of placental infarcts. The article highlights the importance of Doppler techniques in diagnosing placental anomalies and describes the correlation between clinical, ultrasonography, macroscopic, and histopathological findings in a patient with severe pre-eclampsia and placental infarcts.

This article, titled "EP09.23: Prenatal diagnosis of absent semilunar valve: from the first trimester," discusses the ultrasound characteristics and diagnosis of absent semilunar valve in fetuses. The study analyzed data from cases diagnosed at the Department of Ultrasound Medicine of Fujian Provincial Maternal and Child Health Hospital between 2011 and 2023. The majority of the 52 diagnosed cases were identified during the first trimester, with different types of absent semilunar valve identified. The article concludes that the presence of "Back‐and‐forth" blood flow signals in major arteries is a reliable indicator for diagnosing an absent semilunar valve, and that it is possible to diagnose this condition during the first trimester of pregnancy.

This article discusses the role of Tricuspid Annular Plane Systolic Excursion (TAPSE) in monitoring cardiac function in fetuses diagnosed with fetal intra-abdominal umbilical vein varix (FIUVV). The study reviewed cases of FIUVV diagnosed between 2018 and 2023 and collected data on varix diameter, associated anomalies, and pregnancy outcomes. The findings suggest that fetuses with FIUVV have a hyperdynamic cardiac state, and TAPSE may be a useful tool in monitoring these fetuses and identifying cardiac decompensation. No cases of thrombosis or fetal demise were reported in the study group. [Extracted from the article]

This article discusses a study conducted in Argentina that aimed to determine the effectiveness of serial cervical length (CL) measurements as a predictor of spontaneous preterm birth (sPTB) in uncomplicated triplet pregnancies. The study involved a retrospective chart review of triplets followed at a single University Hospital from 2011 to 2024. The results showed that serial CL measurements had a good performance in predicting sPTB in uncomplicated triplets. However, the authors note that further studies are needed to fully establish the value of this strategy in clinical practice. [Extracted from the article]

• Exposure to ADs seems to be associated with fetal mortality. • This may exist more readily for exposure during the first trimester of pregnancy. • Citalopram, clomipramine and venlafaxine seem to be particularly involved. • Further research should investigate the safety of ADs during early pregnancy. Recent research suggests that fetal exposure to antidepressants (ADs) is significantly associated with fetal death, including stillbirth. However, there has been limited investigation into the timing of AD exposure during pregnancy, the specific effect of each drug, and the possibility of indication bias. To address these gaps in knowledge, we conducted a systematic review of literature and disproportionality analyses using the WHO Safety Database (VigiBaseⓇ). The systematic review provided evidence for increased risks of fetal death with exposure to any selective serotonin reuptake inhibitor (SSRI) at any time of pregnancy, stillbirth with exposure to any AD during the first trimester, and stillbirth with exposure to any SSRI during the first trimester. Disproportionality analyses revealed significant associations with citalopram, clomipramine, paroxetine, sertraline, and venlafaxine. Combining both sets of results, we conclude that exposure to ADs, especially during the first trimester of pregnancy, seems to be associated with fetal mortality, and that ADs with highest placental transfer may be particularly involved. Further research should investigate the links between ADs during early pregnancy and fetal mortality. [ABSTRACT FROM AUTHOR]

Fetal growth velocity is being recognized as an important parameter by which to monitor fetal wellbeing, in addition to assessment of fetal size. However, there are different models and standards in use by which velocity is being assessed. We wanted to investigate 3 clinically applied methods of assessing growth velocity and their ability to identify stillbirth risk, in addition to that associated with small for gestational age. Retrospective analysis of prospectively recorded routine-care data of pregnancies with 2 or more third trimester scans in New Zealand. Results of the last 2 scans were used for the analysis. The models investigated to define slow growth were (1) 50+ centile drop between measurements, (2) 30+ centile drop, and (3) estimated fetal weight below a projected optimal weight range, based on predefined, scan interval specific cut-offs to define normal growth. Each method's ability to identify stillbirth risk was assessed against that associated with small-for-gestational age at last scan. The study cohort consisted of 71,576 pregnancies. The last 2 scans in each pregnancy were performed at an average of 32+1 and 35+6 weeks of gestation. The 3 models defined "slow growth" at the following differing rates: (1) 50-centile drop 0.9%, (2) 30-centile drop 5.1%, and (3) below projected optimal weight range 10.8%. Neither of the centile-based models identified at-risk cases that were not also small for gestational age at last scan. The projected weight range method identified an additional 79% of non–small-for-gestational-age cases as slow growth, and these were associated with a significantly increased stillbirth risk (relative risk, 2.0; 95% CI, 1.2–3.4). Centile-based methods fail to reflect adequacy of fetal weight gain at the extremes of the distribution. Guidelines endorsing such models might hinder the potential benefits of antenatal assessment of fetal growth velocity. A new, measurement-interval-specific projection model of expected fetal weight gain can identify fetuses that are not small for gestational age, yet at risk of stillbirth because of slow growth. The velocity between scans can be calculated using a freely available growth rate calculator (www.perinatal.org.uk/growthrate). [Display omitted] [ABSTRACT FROM AUTHOR]

The investigation of the fetal umbilical–portal venous system is based on the premise that congenital anomalies of this system may be related to adverse perinatal outcomes. Several small retrospective studies have reported an association between umbilical–portal–systemic venous shunts and intrauterine growth restriction. However, the prevalence of portosystemic shunts in the fetal growth restricted population is yet to be determined. The aims of this study were (1) to determine the prevalence of fetal umbilical–portal–systemic venous shunts in pregnancies complicated by intrauterine growth restriction and (2) to compare the perinatal and neonatal outcomes of pregnancies with intrauterine growth restriction with and without umbilical–portal–systemic venous shunts. This was a prospective, cross-sectional study of pregnancies diagnosed with intrauterine growth restriction, as defined by the Society for Maternal-Fetal Medicine intrauterine growth restriction guidelines. All participants underwent a detailed anomaly scan, supplemented with a targeted scan of the fetal portal system. Venous shunts were diagnosed using color Doppler mode. The perinatal outcomes of pregnancies with intrauterine growth restriction with and without umbilical–portal–systemic venous shunts were compared. A total of 150 cases with intrauterine growth restriction were recruited. The prevalence of umbilical–portal–systemic venous shunts in our cohort was 9.3% (n=14). When compared with the control group (intrauterine growth restriction without umbilical–portal–systemic venous shunts, n=136), the study group had a significantly lower mean gestational age at the time of intrauterine growth restriction diagnosis (29.7±5.6 vs 32.47±4.6 weeks of gestation; P =.036) and an earlier gestational age at delivery (33.50±6.0 vs 36.13±2.8; P =.005). The study group had a higher rate of fetal death (21.4% vs 0.7%; P <.001) and, accordingly, a lower rate of live births (71.4% vs 95.6%; P =.001). Additional associated fetal vascular anomalies were significantly more prevalent in the study group than in the control group (35.7% vs 4.4%; P ≤.001). The rate of other associated anomalies was similar. The study group had a significantly lower rate of abnormal uterine artery Doppler indices (0% vs 40.4%; P =.011) and a higher rate of abnormal ductus venosus Doppler indices (64.3% vs 23%; P =.001). There were no cases of hypertensive disorders of pregnancy in the study group, whereas the control group had an incidence of 12.5% (P =.16). Other perinatal and neonatal outcomes were comparable. Umbilical–portal–systemic venous shunt is a relatively common finding among fetuses with growth restriction. When compared with pregnancies with intrauterine growth restriction with a normal portal system, these pregnancies complicated by intrauterine growth restriction and an umbilical–portal–systemic venous shunt are associated with a different Doppler flow pattern, an increased risk for fetal death, earlier presentation of intrauterine growth restriction, a lower gestational age at delivery, additional congenital vascular anomalies, and a lower rate of pregnancy-induced hypertensive disorders. Meticulous sonographic evaluation of the portal system should be considered in the prenatal workup of intrauterine growth restriction, as umbilical–portal–systemic venous shunts may affect perinatal outcomes.

BackgroundDetermining the cause of intrauterine fetal death is essential for patients to manage their next pregnancy. However, in the majority of cases of fetal death, the cause remains unexplained despite comprehensive evaluation, especially in the cases of twins. Among twin pregnancies, conditions of monochorionic twinning, commonly regarded as monozygotic, are more complicated than dichorionic ones.Case summaryWe systematically evaluated the cause of fetal death for a Han Chinese woman with monochorionic twinning following in vitro fertilization/embryo transfer. Discrepant karyotypes were unexpectedly discovered between the twins. One fetus had an aneuploid male karyotype (46, XY), dup (9) (p24.3-q13), and the other had a normal female karyotype (46, XX). We considered that the male died of aberration of chromosome 9 and the female died of subsequent acute exsanguination through vascular anastomosis.ConclusionThis study demonstrated the importance of recognizing the presence of monochorionic dizygotic twinning and the challenges of clinical management for twins following in vitro fertilization/double embryo transfer.

BackgroundMedical management of early pregnancy loss is an alternative to uterine aspiration, but standard medical treatment with misoprostol commonly results in treatment failure. We compared the efficacy and safety of pretreatment with mifepristone followed by treatment with misoprostol with the efficacy and safety of misoprostol use alone for the management of early pregnancy loss.MethodsWe randomly assigned 300 women who had an anembryonic gestation or in whom embryonic or fetal death was confirmed to receive pretreatment with 200 mg of mifepristone, administered orally, followed by 800 μg of misoprostol, administered vaginally (mifepristone-pretreatment group), or 800 μg of misoprostol alone, administered vaginally (misoprostol-alone group). Participants returned 1 to 4 days after misoprostol use for evaluation, including ultrasound examination, by an investigator who was unaware of the treatment-group assignments. Women in whom the gestational sac was not expelled were offered expectant management, a second dose of misoprostol, or uterine aspiration. We followed all participants for 30 days after randomization. Our primary outcome was gestational sac expulsion with one dose of misoprostol by the first follow-up visit and no additional intervention within 30 days after treatment.ResultsComplete expulsion after one dose of misoprostol occurred in 124 of 148 women (83.8%; 95% confidence interval [CI], 76.8 to 89.3) in the mifepristone-pretreatment group and in 100 of 149 women (67.1%; 95% CI, 59.0 to 74.6) in the misoprostol-alone group (relative risk, 1.25; 95% CI, 1.09 to 1.43). Uterine aspiration was performed less frequently in the mifepristone-pretreatment group than in the misoprostol-alone group (8.8% vs. 23.5%; relative risk, 0.37; 95% CI, 0.21 to 0.68). Bleeding that resulted in blood transfusion occurred in 2.0% of the women in the mifepristone-pretreatment group and in 0.7% of the women in the misoprostol-alone group (P=0.31); pelvic infection was diagnosed in 1.3% of the women in each group.ConclusionsPretreatment with mifepristone followed by treatment with misoprostol resulted in a higher likelihood of successful management of first-trimester pregnancy loss than treatment with misoprostol alone.

Chronic Kidney Disease affects approximately 10% of the world's adult population: it is within the top 20 causes of death worldwide, and its impact on patients and their families can be devastating. World Kidney Day and International Women's Day in 2018 coincide, thus offering an opportunity to reflect on the importance of women's health and specifically their kidney health, on the community, and the next generations, as well as to strive to be more curious about the unique aspects of kidney disease in women so that we may apply those learnings more broadly. Girls and women, who make up approximately 50% of the world's population, are important contributors to society and their families. Gender differences continue to exist around the world in access to education, medical care, and participation in clinical studies. Pregnancy is a unique state for women, offering an opportunity for diagnosis of kidney disease, but also a state where acute and chronic kidney diseases may manifest, and which may impact future generations with respect to kidney health. There are various autoimmune and other conditions that are more likely to impact women with profound consequences for child bearing, and on the fetus. Women have different complications on dialysis than men, and are more likely to be donors than recipients of kidney transplants. In this editorial, we focus on what we do and do not know about women, kidney health, and kidney disease, and what we might learn in the future to improve outcomes worldwide.

ObjectiveThe significance of polyhydramnios of one twin in the absence of oligohydramnios of the cotwin in monochorionic diamniotic (MCDA) twin pregnancies (polyhydramnios affecting a recipient-like twin [PART]) is unknown. Our aim is to assess the risk of progression to twin-twin transfusion syndrome (TTTS) with PART, progression to ≥ stage II TTTS, and neonatal survival.Study designThis study was a retrospective cohort study of MCDA twin pregnancies with PART evaluated at a referral center from 2008 to 2015.ResultsSixty-four MCDA twin pregnancies with PART were identified. Fifteen (23.4%) progressed to TTTS, including 10 (15.6%) who progressed to ≥ stage II TTTS. Three pregnancies were terminated and one underwent selective reduction by radiofrequency ablation. Overall survival was 113 out of 128 (88.3%). Of those who remained stable, 91.8% (N = 45) had survival of both neonates. In multivariate analysis, the presence of arterioarterial (A-A) anastomosis by in utero Doppler ultrasound was associated with decreased risk of progression to TTTS (odds ratio: 0.12, p = 0.03, 95% confidence interval: 0.02-0.78).ConclusionMost MCDA twin pregnancies with PART do not progress to TTTS and have a favorable prognosis. Progression rates are higher than observed in uncomplicated MCDA twins; however, so close surveillance is warranted. The presence of an A-A anastomosis appears to confer decreased risk of progression to TTTS.

IntroductionAdequate nutrient intake during pregnancy is an important key factor affecting fetal growth and birth outcomes, as well as maternal health, as demonstrated by experimental animal studies. However, the few human studies available, especially those conducted in the least developed countries (LDCs), are much less consistent. Therefore, this study aimed to investigate the association between dietary diversification during pregnancy and birth outcomes in Gojjam, Ethiopia.MethodologyA facility-based prospective cohort study was conducted on 416 pregnant mothers (exposed and non-exposed) from December 2019 to January 2020. Information about the Women's Dietary Diversity Score (WDDS) was collected using the Food and Agricultural Organization's guidelines. Data were collected through interviewer-administered questionnaires and measurements. Log-binomial regression analysis was performed to estimate the relative risk of adverse birth outcomes. Energy, macronutrient, and micronutrient amounts were calculated using the nutrition survey software version 2007. The differences between groups were noticed using analysis of variance. Eta squared was estimated in the current study.ResultsThe overall magnitude of low birth weight, preterm birth, and stillbirth in the study area, respectively, was 41%, 38%, and 4%. After adjustment for baseline characteristics, this study revealed that pregnant women in the inadequate WDDS group were at increased risk of LBW (ARR = 6.4; 95% CI: 3.4, 12) and PTD (ARR = 6.3; 95% CI: 3.3, 11.95) as compared with their counterparts but no difference in the occurrence of stillbirth (ARR = 1.08; 95% CI: 0.20, 5.79).ConclusionOverall, this study found a large magnitude of low birth weight and preterm birth. Inadequate intake of dietary diversity during pregnancy significantly increased the rate of low birth weight and preterm birth. Thus, we recommend the concerned body to work on improving the feeding practices of pregnant mothers in the study area.

A high birth weight discordance (BWD) places twins at high risks of adverse perinatal outcomes; however, there is no commonly accepted definition of intertwin BWD. Given that gestational age (GA) is closely associated with both BWD and adverse neonatal outcomes, the aim of our study is to develop a measure that takes both BWD and GA into account to define BWD and explore the potentially optimal delivery time in dichorionic twins, with the balance against the risk of intrauterine demise and adverse neonatal outcomes. About 99,000 mixed gender twin pairs from the US matched multiple birth file from 1995 to 2000 were enrolled in our study. We set up a two-dimensional matrix model to select the BWD cutoff point related to outcomes. The optimal delivery time was identified based on the risks of adverse neonatal outcomes and fetal death by GA. The combination of BWD and GA had a higher predictive performance for adverse neonatal outcomes than BWD alone (area under ROC curve (AUC): 0.816 vs. 0.523, p <.001). When GA was controlled for, the growth discordant cutoff point was BWD at the 40% level. The optimal delivery time suggested in dichorionic twins with BWD higher than 40% was identified at 33–34 gestational weeks. The combination of BWD and GA was a better predictor for adverse neonatal outcomes than BWD alone. In dichorionic twins with BWD >40%, pregnancy may be continued till 33–34 gestation weeks if there is no indication for immediate delivery. [ABSTRACT FROM AUTHOR]

Introduction: One-third of fetal soft tissue tumors are malignant and include congenital fibrosarcoma (CF). We report two fetal CFs arising in the posterior mediastinum. Case Presentation: In case 1, the CF resulted in a mediastinal shift, extensive infiltration of the tumor around adjacent structures, pulmonary hypoplasia, pleural effusion, and rapid growth. The pregnancy was terminated. Case 2 had multiple intrathoracic masses, thoracic hypoplasia, pleural effusion, and fetal death. Both were diagnosed as fibrosarcoma at fetopsy. Discussion: Although congenital CF tends to be locally aggressive with a low metastatic rate, it tends to grow rapidly and the tumor location can affect fetal survival. In Case 1, the tumor demonstrated locally aggressive behavior whereas multiple distant metastases such as lung, liver, adrenals, and left eye were detected in Case 2. The tumor was directly responsible for intrauterine fetal demise in the second case. [ABSTRACT FROM AUTHOR]

Background: Waterpipe smoking is associated with maternal and fetal complications, and valid data contribute to evidence-based planning. This study was conducted to determine the prevalence and factors related with waterpipe smoking among pregnant women of Zahedan city in 2020. Methods: This cross-sectional study was conducted in 2020, and 400 pregnant women in the third trimester of pregnancy who lived in Zahedan participated in it by single stage randomized cluster sampling. A questionnaire was used to measure awareness of waterpipe complications, and another one investigated the status of waterpipe smoking to collect data. For data analysis, descriptive statistics and multiple logistic regression were used through SPSS 21. Results: The findings indicated that the prevalence of waterpipe smoking was 18.8%. In the waterpipe smoking group, 46.6% smoked every day, 89.3% had tried to reduce the smoking, and 64.8% reported fetal death as their main motivation to reduce smoking. Only 5.6% of subjects stated receiving training as the reason for reduction of their waterpipe smoking. The women's level of education, economic status, ethnicity, and awareness of the risks of waterpipe smoking were the predictors for waterpipe smoking (P < 0.05, P = 0.03, P = 0.006, and P < 0.001, respectively). Conclusions: The results of this study show the high prevalence of waterpipe smoking in pregnant women of Zahedan. Further investigation and training in this regard are essential for pregnancy as well as pre-pregnancy care. Special attention should be paid to groups with better economic status and level of education, Baluch women, and those with low level of awareness. [ABSTRACT FROM AUTHOR]

Liver disease in pregnancy can be classified into pregnancy-related, liver disease coincident with pregnancy or preexisting liver disease. Acute fatty liver of pregnancy (AFLP) is a rare liver disorder that is caused by defects in mitochondrial beta (β) oxidation of fatty acids. In view of its fulminant presentation and rapid progression to multiple organ failure (MOF), AFLP carries high maternal and fetal mortality. These patients are commonly present in the third trimester of pregnancy with gastrointestinal symptoms and complications such as hypoglycemia, lactic acidosis, hyperammonemia, leukocytosis, liver dysfunction, coagulopathy, and renal dysfunction. Diagnosis is mostly based on the Swansea diagnostic criteria and by excluding other etiologies of liver dysfunction. Liver biopsy is rarely performed owing to underlying coagulopathy and thrombocytopenia. In this case series, we intend to share our experience of managing four cases of AFLP that were admitted to the intensive care unit with fetal demise and MOF. [ABSTRACT FROM AUTHOR]

Objectives: Pregnancy loss is associated with distress which can have a significant emotional impact on women and their spouses including a lower sexual quality of life and sexual dysfunction. The present study aimed to assess sexual quality of life and sexual function in women after fetal death. Material and methods: A total of 110 women with a history of pregnancy loss hospitalized in the Clinic of Obstetrics and Gynecology were included. In order to evaluate the sexual quality of life and sexual functions the standardized questionnaires - the Sexual Quality of Life (SQoL-F) and Female Sexual Function Index (FSFI), respectively were used. Results: Women declared a lower sexual quality of life. Most of them (52.73%) were at a risk of sexual dysfunction in the areas of desire (4.15 ± 1.21) and orgasm (3.82 ± 1.48). The older the age and length of the relationship was (p = 0.002; r = -0.298) the worse the sexual quality of life (p < 0.001) and sexual function were (p < 0.05). The sexual quality of life (p < 0.001) and sexual function in the area of desire (p = 0.001), arousal (p = 0.001) and orgasm (p < 0.001) were significantly better in the women who have experienced one pregnancy loss than in those with more than one pregnancy loss. Sexual function was better in women who did not plan to have a pregnancy. The week in which the pregnancy was lost and the fact of having other children have not been statistically significant. Conclusions: The sexual quality of life and female sexual function in women after an experience of fetal death were less satisfying. [ABSTRACT FROM AUTHOR]

Objective: Our study wants to assess the outcome of moderate small for gestational age (SGA) infants at term with reference to the week they find themselves in at birth in uncomplicated pregnancies. Material and Methods: The database is made of women delivering in Switzerland from 2005 through 2017 selecting uncomplicated singleton pregnancies in cephalic presentation, with birthweight between the 5th and 10th percentiles, and a gestational age at delivery between 37 0/7 and 41 6/7 weeks. We considered poor perinatal outcomes as either umbilical cord arterial pH<7.15, 5’Apgar score <7, admission to the neonatal intensive care unit, and/or perinatal mortality. Statistical analyses were performed using contingency tests and Spearman rank correlation adopting a p<0.05 as significant. Results: Out of the 429,863 available deliveries, we identifyied 1,796 cases matching our criteria. The final sample includes 1,327 (73.9%) vaginal deliveries and 473 (26.1%) caesarean sections (CS) and it is worth mentioning that the rate of secondary CS (r=0.828; p=0.03) and vaginal deliveries (r=0.965; p=0.01) increased with advancing gestation. In addition, 306 (19.3%) patients had induced labours. This is particularly concentrated between 40 and 41 weeks of gestation (r=0.967; p=0.002); among them, 80% delivered vaginally and 20% with a secondary CS. The percentage of adverse outcome was 16.9%, 11.3%, 8.6%, 18.8%, and 21.7% for gestational week 37, 38, 39, 41 and 42, respectively, whereas only 3 cases (0.17%) of intrauterine death occurred. Conclusion: Moderate SGA infants are best delivered between 39 0/7 and 40 0/7 weeks of gestation. [ABSTRACT FROM AUTHOR]

Background: This study aimed to investigate and compare the prenatal and neonatal outcomes of monochorionic twin pregnancies complicated with fetal growth restriction (sFGR) with or without twin-to-twin transfusion syndrome (TTTS) after cord occlusion by radiofrequency ablation (RFA). Methods: This prospective cross-sectional study was conducted in women with monochorionic twin pregnancies of 16 to 26 weeks of gestational age (GA) in an academic hospital from 2016 to 2020. Demographic and obstetrical characteristics such as cervical length, GA of RFA and delivery, amnioreduction, cesarean section (C/S) rate, and maximum vertical pocket as well as prenatal, neonatal, and maternal outcomes were evaluated and compared between groups using Statistical Package for the Social Sciences (SPSS). Mann-Whitney U test or independent t test was used for quantitative data and Chi square test was applied for comparing qualitative variables. The significance level of tests was 0.05. Results: Totally 213 (106 sFGR and 107 TTTS+sFGR) cases were enrolled. The mean of maternal age (P=0.787), body mass index (P=0.932), gestational age at RFA (P=0.265), as well as gestational age of delivery (P=0.482), and C/S rate (P=0.124) were not significant between the two groups, but a significant difference (P<0.001) in cervical length was observed between the two groups. No significant differences were found in newborn and fetal outcomes such as fetal demise (P=0.827), PPROM (P=0.233), abortion (P=0.088), and admission to intensive care unit (P=0.822) between the groups. Conclusion: Although worse fetal and neonatal outcomes were expected in the TTTS+sFGR group after RFA, no significant difference was observed between groups. [ABSTRACT FROM AUTHOR]

Fasting during pregnancy is an enigma: why would a woman restrict her food intake during a period of increased nutritional need? Relative to the costs to healthy individuals who are not pregnant, the physiological costs of fasting in pregnancy are amplified, with intrauterine death being one possible outcome. Given these physiological costs, the question arises as to the socioecological factors that give rise to fasting during pregnancy. There has been little formal research regarding the emic perceptions and socioecological factors associated with such fasting. This study therefore took an emic approach and investigated the types of fasts that are common in pregnancy, women's perceptions of the consequences of fasting, and the socioecological models of pregnancy fasting in three Indian communities. This cross-sectional study took place in Bhubaneshwar, Odisha state, and Mysore, Karnataka state, among two populations of Hindu women and one population of Muslim women (N = 85). In total, 64% of women fasted in prior pregnancies. Findings revealed variation in the number and types of fasts that are common in pregnancy across the three communities. Each community reported differences in positive and negative consequences of fasting, with varied emphasis on reproductive health, religiosity, and general health and well-being. Finally, quantitative analyses indicated that the best-fitting model for fasting during pregnancy was religiosity, and the poorest-fitting models were resource scarcity and general health. This study provides insight into motivations for such fasting and highlights the need to investigate the relationship between supernatural beliefs and maternal–fetal protection further, as well as social functions of pregnancy fasting within the family and community.

Objective: To investigate twin reversed arterial perfusion (TRAP) sequence for the prediction of TRAP‐related adverse pregnancy outcomes at the gestational age of 11–14 weeks. Methods: Pregnant women in the first trimester diagnosed with TRAP were recruited at West China Second University Hospital from January 2015 to June 2018. Systematic screening for the pump twin's crown‐rump length (CRL) and acardiac twin's upper pole‐rump length (URL) was conducted using ultrasonic detection. The (CRL – URL)/CRL and URL/CRL ratios were used to assess the pregnancy outcomes for the pump twin. Twenty‐one pregnant women aged 21–39 years with a gestation of 11–14 weeks were recruited. Results: TRAP was diagnosed on average (± standard deviation (SD)) at pregnancy week 13.1 ± 0.18. The pump twins' mean (± SD) CRL was 6.65 ± 1.1 cm. The incidence of intrauterine death for the pump twins was 19.0% (n = 4), the miscarriage rate was 14.3% (n = 3), and the live birth rate was 66.7% (n = 14). The (CRL – URL)/CRL ratios between the nonsurvival (intrauterine death and miscarriage) and survival groups significantly differed (0.33 ± 0.08 vs. 0.58 ± 0.08, p < 0.05). Similarly, the URL/CRL ratios between the nonsurvival and survival groups significantly differed (0.67 ± 0.08 vs. 0.42 ± 0.08, p < 0.05). Conclusion: The (CRL – URL)/CRL and URL/CRL ratios were valuable indicators for determining pregnancy outcomes of pump twins with TRAP at an early gestational age. [ABSTRACT FROM AUTHOR]

Lithopedion is a rare condition secondary to retention and calcification of an unrecognized intra‐abdominal (usually ectopic) pregnancy after a fetal death, which occurred after three months of gestation. It accounts for 1.5%–2% of cases of ectopic pregnancy. We report the case of a 72‐year‐old nulligravida woman who died about 72 h after being kicked in the abdomen during a fight. At autopsy, an intra‐abdominal calcified fetus, acute generalized peritonitis, and ileal perforation were observed. The estimated gestational age of the fetus was 37 weeks (based on femur length) and the lithopedion had a weight of 750 g and a size of 15 × 12 × 9 cm. The age of menopause and the duration of retention are not known. This is the first case of this entity identified in Senegal. [ABSTRACT FROM AUTHOR]

Introduction. Stillbirth has been documented as an outcome of SARS-CoV-2 infection in pregnancy. Placental hypoperfusion and inflammation secondary to maternal immune response seem to play a role in the cascade of events that contribute to fetal death. The aim of our study is to report a perinatal outcome of SARS-CoV-2 infection in pregnancy adding information to the pool of data on COVID-19 pregnancy outcomes. Case Presentation. This is the first stillbirth case series occurring in pregnant women infected with SARS-CoV-2 in a Portuguese cohort. Between April 2020 and March 2021, we had 2680 births in our centre, of which 130 (4.95%) involved mothers infected with SARS-CoV-2. Of total births, there were 14 stillbirths (0.52%), accounting for the highest stillbirth rate we have had in the last 5 years. Among these 14 stillbirths, 5 (35.71%) occurred in SARS-CoV-2-infected mothers. We report the clinical features and placental histopathologic findings of 4 stillbirth cases that occurred in our hospital. Discussion. The stillbirth rate among SARS-CoV-2-infected pregnant women (5/130; 3.84%) was significantly increased compared to noninfected patients (9/2550; 0.35%). Most women (3/4) were asymptomatic for COVID-19, a surprising outcome, given the current literature. All cases had histologic exams showing placental signs of vascular malperfusion, although we acknowledge that 3/5 had obstetric conditions related to placental vascular impairment such as preeclampsia and HELLP syndrome. Conclusion. Stillbirth can be a perinatal consequence of SARS-CoV-2 infection in pregnancy, even in asymptomatic patients. We urge more studies to explore the association between SARS-CoV-2 infection and the risk of stillbirth. [ABSTRACT FROM AUTHOR]

Perinatal loss may deeply affect the attachment relationships of mothers and their next-born children. The aim was to explore the subjective perceptions of mothers, who had fetal death during the first pregnancy, and their adult subsequent firstborn children regarding the impact of the perinatal loss on the mother-child relationship and children's self-perception. Fifteen mothers who experienced a fetal death during the first pregnancy and their adult subsequent firstborn children were interviewed. A Grounded Theory approach was used. Five main themes were identified: fetal death as a real loss producing prolonged grief; the importance of the communication about the dead sibling; creating and maintaining a relationship with the lost sibling; the mother-subsequent child relationship: between detachment and overprotection; significant effects of fetal death on adult subsequent children's self-perception. Results highlighted a deep impact of fetal death on the subsequent mother-child relationship, as perceived by both mothers and adult children. [ABSTRACT FROM AUTHOR]

We used an abortion-prone mouse model, generated by mating female CBA/J mice with male DBA/2JJcl mice, to examine the effects of changes in the Th1/Th2 cell ratio and the percentage of regulatory T (Treg) cells on the maintenance of pregnancy. We subcutaneously injected female CBA/J mice once each with 50 µg/mouse of Dermatophagoides farinae (Df) extract and the squalene-based adjuvant (SquA); 10 days later, these mice were mated with male DBA/2JJcl mice. Compared with injection of vehicle or adjuvant, the Df treatment decreased the Th1/Th2 cell ratio and concomitantly increased the percentage of Treg cells in the spleen. In addition, fetal death rates were decreased. We then explored a substance which shifted the Th1/Th2 balance toward Th1 side. We found that 50 µg/mouse of keyhole limpet hemocyanin (KLH) increased the splenic Th1/Th2 cell ratio of nonpregnant female CBA/J mice. We subcutaneously injected female CBA/J mice with KLH and SquA; 10 days later, these mice were mated with male DBA/2JJcl mice. Compared with injection of vehicle or adjuvant, treatment with KLH enhanced the Th1 bias during pregnancy and increased the fetal death rate. The percentage of Treg cells, however, was increased in these KLH-injected pregnant mice contrary to our presumption. All collected data showed strong positive correlation between the Th1/Th2 cell ratio and fetal death rate. The increase in Treg cells independent of effects on the fetal death rate suggests that Treg cells do not necessarily induce maternal tolerance to the fetus but may prevent excessive Th1/Th2 imbalance during pregnancy.

Objective: To assess obstetricians' personality traits (empathy, locus of control [LoC], situational affect) and relate these to stress coping when making the diagnosis and delivering the news of late fetal death to parents.Methods: Cross-sectional questionnaire study.Results: 341 Austrian obstetricians (72.7% females) participated in this online survey. Participants' mean age was 46.4 ± 10.8 years. The majority of participants (n = 158, 46.3%) had been previously involved in the diagnosis of fetal death and subsequent breaking news up to five times. We observed no gender-specific differences in physicians' stress coping, including situational affect, perceived stress, challenge, self-concept, or perceived control, nor in internal or external LoC, and perspective taking. Female obstetricians showed significantly higher trait empathy and reported higher levels of distress regarding fetal death than males. Obstetricians with greater experience in dealing with fetal death (>11 times) reported a higher ability to cope with stress as reflected by lower situational affect, less perceived stress, less challenge, and higher situational control.Conclusion: While obstetricians' stress coping in diagnosing and communicating fetal death is independent of physicians' gender, greater ability to empathize with the parents diminishes overall sense of control and affect over the situation, whereas increased level of clinical experience with fetal death supports all domains of control and stress coping.

Despite a recent endorsement from official and professional bodies unequivocally recommending COVID-19 vaccination, vaccine hesitancy among pregnant people remains high. The accumulated evidence demonstrates that pregnant people are a special risk group for COVID-19, with an increased risk of intensive care unit admission, extracorporeal membranous oxygenation requirement, preterm birth, and perinatal death. These risks are further increased with some variants of concern, and vaccination of pregnant people reduces the COVID-19-related increase in maternal or fetal morbidity. Data from more than 180,000 vaccinated persons show that immunization against COVID-19 with an mRNA vaccine is safe for pregnant people. Many observational studies comparing perinatal outcomes between vaccinated and unvaccinated pregnant people have had reassuring findings and did not demonstrate harmful effects on pregnancy or the newborn. Immunization with mRNA vaccines does not increase the risk of miscarriage, preterm delivery, low birthweight, maternal or neonatal intensive care unit admission, fetal death, fetal abnormality, or pulmonary embolism. Moreover, observational data corroborate the findings of randomized trials that mRNA vaccination is highly effective at preventing severe SARS-CoV-2 infection in pregnant people, emphasizing that the potential maternal and fetal benefits of vaccination greatly outweigh the potential risks of vaccination. Ensuring pregnant people have unrestricted access to COVID-19 vaccination should be a priority in every country worldwide. [ABSTRACT FROM AUTHOR]

Objectives: To assess the impact of marginal (MCI) or velamentous (VCI) cord insertion on uterine artery pulsatility index (UtA PI), preeclampsia (PE), and offspring's birthweight (BW). Methods: A retrospective cohort study of singleton pregnancies, undergoing routine anomaly scan at 20+0–23+6 gestational weeks, was conducted between 2016 and 2020. The effect of placental cord insertion on BW and UtA mean PI z‐scores was assessed using the t test or analysis of variance and post‐hoc tests; their association with PE was evaluated with the chi‐square test. A multivariate logistic regression model was employed to assess the independent association of placental cord insertion and UtA PI z‐score with PE, BW <10th, <5th centile, and intrauterine death (IUD), using specific confounders. Results: The study population included 4453 pregnancies. Conception via assisted reproductive technology (ART) was associated with increased risk of abnormal cord insertion (odds ratio [OR]: 2.237; 95% confidence interval [CI]: 1.561–3.206; P <.001). Women with MCI/VCI had higher mean UtA PI z‐score than those with central/eccentric (0.29 vs 0.01; mean difference: −0.28; 95% CI: −0.399 to −0.165; P <.001). MCI/VCI were associated with higher rates of BW <10th centile (central/eccentric: 16.2% vs MCI: 21.9% vs VCI: 35.7%; P <.001) and BW <5th centile (9.8 vs 15.1 vs 23.2%, respectively; P <.001). No association was identified between MCI/VCI and PE (P =.968). Finally, VCI (aOR: 13.717; 95% CI: 1.576–119.379; P =.018) and increased BMI (aOR: 1.167; 95% CI: 1.071–1.271; P <.001) significantly correlated with IUD. Conclusions: Abnormal cord insertion is more common in ART pregnancies. MCI/VCI are associated with higher mean UtA PI and lower BW centile, but not with increased risk of PE. [ABSTRACT FROM AUTHOR]

Background: In asymptomatic women with cervical length ≤10 mm, vaginal progesterone has a limited effect in reducing the rate of preterm delivery., Objective: This study aimed to estimate the rate of preterm delivery and mean latency period to delivery in asymptomatic women with no history of preterm delivery and a cervical length of ≤10.0 mm undergoing or not undergoing cerclage and who were not treated with vaginal progesterone., Study Design: This was a retrospective analysis of asymptomatic patients with singleton pregnancies and no history of preterm delivery with an incidental finding of a cervical length of ≤10.0 mm measured by transvaginal ultrasound during midtrimester scan. Of note, 56 patients (63.6%) underwent cerclage placement and 32 patients (36.4%) did not, none of them received vaginal progesterone. Patients with evidence of advanced dilation, prolapsing membranes, ruptured membranes, or positive signs of infection were not candidates for cerclage placement and were excluded from the analysis. Differences in the prevalence of preterm delivery, mean gestational age at delivery, and mean latency from very short cervix identification to delivery between the 2 groups were calculated. Associations between cerclage and preterm delivery adjusted for maternal characteristics and fetal weight were estimated., Results: The median gestational ages at the time of cervical length measurement were 20 6/7 weeks (interquartile range, 17 5/7 to 23 3/7) in the cerclage group and 21 5/7 weeks (interquartile range, 17 6/7 to 23 6/7) in the no-cerclage group (P=.02). No difference in cervical length was observed between patients who had a cerclage (5.9±3.1 mm) and those who did not have a cerclage (6.5±3.2 mm) (P=.4). The prevalence of preterm delivery in women with cerclage vs women without cerclage was as follows: PTD at <37 weeks of gestation (31/56 [55.3%] in the cerclage group vs 28/32 [87.5%] in the no-cerclage group; adjusted odds ratio, 0.17; 95% confidence interval, 0.05-0.62; P=.008), PTD at ≤34 weeks of gestation (27/56 [48.2%] in the cerclage group vs 24/32 [75.0%] in the no-cerclage group; adjusted odds ratio, 0.16; 95% confidence interval, 0.05-0.55; P=.02), and PTD at ≤28 weeks of gestation (19/56 [33.9%] in the cerclage group vs 22/32 [68.7%] in the no-cerclage group; adjusted odds ratio, 0.15; 95% confidence interval, 0.05-0.51; P=.002). The median gestational ages at delivery were 32 6/7 weeks (interquartile range, 19 1/7 to 40 1/7) in the cerclage group and 28 1/7 weeks (interquartile range, 20 1/7 to 40 2/7) in the no-cerclage group (P=.001). The median latencies from the time of cervical length measurement to delivery were 84 days (interquartile range, 8-144) in the cerclage group and 43 days (interquartile range, 1-146) in the no-cerclage group (P=.003)., Conclusion: Among low-risk asymptomatic women with a very short cervix (≤10.0 mm) in the midtrimester of pregnancy, women treated with cerclage have an increased latency to delivery and a lower prevalence of preterm delivery than those treated with expectant management., (Copyright © 2024 Elsevier Inc.

Losing a newborn is for many mothers a painful end in which death occurs when life is expected, which makes them live a time of loneliness, personal doubt and feeling of failure. After carrying out a previous qualitative study analyzing the experiences of 25 women who suffered a spontaneous perinatal loss at any time during pregnancy and a systematic review of the factors that affect the emotional response after perinatal losses, a nursing care proposal is presented based on Watson's Theory of Transpersonal Human Care to respond to the needs of women who experience this loss process. This care plan proposal is intended to achieve individualized care for women who suffer perinatal losses adapted to their needs, not only physical but also emotional., (Copyright © 2024 The Author(s).

Acute febrile illness (AFI) in pregnancy is a neglected cause of maternal and foetal mortality and morbidity in low-and middle-income countries. This prospective cohort studied antenatal and postpartum women admitted with acute fever to a tertiary care university teaching hospital from July 2014 to March 2015 for aetiology, maternal and foetal complications, and the impact on maternal mortality ratio (MMR) and perinatal mortality rate. Among the 180 women admitted with AFI, urinary tract infection 54(30%) was the commonest cause, followed by airborne infections (67; 37.2%), peripartum or wound infections (25; 13.8%) and vector-borne diseases (21; 11.6%). Maternal deaths were 4 (2%) and foetal deaths 9 (5%). Post-operative gram-negative sepsis was the most common cause of maternal mortality. The MMR was ten times higher with AFI 2778 against 197 ( p  < 0.0001) among the other hospital deliveries during the same period. Screening for asymptomatic bacteriuria , maintaining aseptic precautions, and vaccination may impact maternal and foetal morbidity significantly., Competing Interests: Declaration of conflicting interestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Objectives: Twin pregnancies are at higher risk of stillbirth compared to singletons. Fetal growth restriction (FGR) is a major cause of perinatal mortality, but its impact on twins vs singletons remains unclear. The primary objective of this study was to investigate the association of FGR and small-for-gestational age (SGA) with stillbirth in twin compared with singleton pregnancies. A secondary objective was to assess these associations stratified by gestational age at delivery. Furthermore, we aimed to compare the associations of FGR and SGA with stillbirth in twin pregnancies using twin-specific vs singleton birth-weight charts, stratified by chorionicity., Methods: This was a retrospective cross-sectional study of pregnancies receiving obstetric care and giving birth between 1999 and 2022 at St George's Hospital, London, UK. The exclusion criteria included triplet and higher-order pregnancies, those resulting in miscarriage or live birth at ≤ 23 + 6 weeks, termination of pregnancy and missing data regarding birth weight or gestational age at birth. Birth-weight data were collected and FGR and SGA were defined as birth weight <5 th and <10 th centiles, respectively. While standard logistic regression was used for singleton pregnancies, the association of FGR and SGA with stillbirth in twin pregnancies was investigated using mixed-effects logistic regression models. For twin pregnancies, intercepts were allowed to vary for twin pairs to account for intertwin dependency. Analyses were stratified by gestational age at delivery and chorionicity. Statistical significance was set at P ≤ 0.001., Results: The study included 95 342 singleton and 3576 twin pregnancies. There were 494 (0.52%) stillbirths in singleton and 41 (1.15%) stillbirths in twin pregnancies (17 dichorionic and 24 monochorionic). SGA and FGR were associated significantly with stillbirth in singleton pregnancies across all gestational ages at delivery: the odds ratios (ORs) for SGA and FGR were 2.36 ((95% CI, 1.78-3.13), P < 0.001) and 2.67 ((95% CI, 2.02-3.55), P < 0.001), respectively, for delivery before 32 weeks; 2.70 ((95% CI, 1.71-4.31), P < 0.001) and 2.82 ((95% CI, 1.78-4.47), P < 0.001), respectively, for delivery between 32 and 36 weeks; and 3.85 ((95% CI, 2.83-5.21), P < 0.001) and 4.43 ((95% CI, 3.16-6.12), P < 0.001), respectively, for delivery after 36 weeks. In twin pregnancies, when stratified by gestational age at delivery, both SGA and FGR determined by twin-specific birth-weight charts were associated with increased odds of stillbirth for those delivered before 32 weeks (SGA: OR, 3.87 (95% CI, 1.56-9.50), P = 0.003 and FGR: OR, 5.26 (95% CI, 2.11-13.01), P = 0.001), those delivered between 32 and 36 weeks (SGA: OR, 6.67 (95% CI, 2.11-20.41), P = 0.001 and FGR: OR, 9.54 (95% CI, 3.01-29.40), P < 0.001) and those delivered beyond 36 weeks (SGA: OR, 12.68 (95% CI, 2.47-58.15), P = 0.001 and FGR: OR, 23.84 (95% CI, 4.62-110.25), P < 0.001). However, the association of stillbirth with SGA and FGR in twin pregnancies was non-significant when diagnosis was based on singleton charts (before 32 weeks: SGA, P = 0.014 and FGR, P = 0.005; 32-36 weeks: SGA, P = 0.036 and FGR, P = 0.008; after 36 weeks: SGA, P = 0.080 and FGR, P = 0.063)., Conclusion: Our study demonstrates that SGA and, especially, FGR are associated significantly with an increased risk of stillbirth across all gestational ages in singleton pregnancies, and in twin pregnancies when twin-specific birth-weight charts are used. © 2024 The Authors.

This study aims to investigate whether trial of labor after cesarean delivery (TOLAC) in women with antepartum fetal death, is associated with an elevated risk of maternal morbidity. A retrospective multicenter. TOLAC of singleton pregnancies following a single low-segment incision were included. Maternal adverse outcomes were compared between women with antepartum fetal death and women with a viable fetus. Controls were matched with cases in a 1:4 ratio based on their previous vaginal births and induction of labor rates. Univariate analysis was followed by multiple logistic regression modeling. During the study period, 181 women experienced antepartum fetal death and were matched with 724 women with viable fetuses. Univariate analysis revealed that women with antepartum fetal death had significantly lower rates of TOLAC failure (4.4% vs. 25.1%, p < 0.01), but similar rates of composite adverse maternal outcomes (6.1% vs. 8.0%, p = 0.38) and uterine rupture (0.6% vs. 0.3%, p = 0.56). Multivariable analyses controlling for confounders showed that an antepartum fetal death vs. live birth isn't associated with the composite adverse maternal outcomes (aOR 0.96, 95% CI 0.21-4.44, p = 0.95). TOLAC in women with antepartum fetal death is not associated with an increased risk of adverse maternal outcomes while showing high rates of successful vaginal birth after cesarean (VBAC)., (© 2024.

Fetal death is defined as the spontaneous cessation of cardiac activity after fourteen weeks of amenorrhea. In France, the prevalence of fetal death after 22 weeks is between 3.2 and 4.4/1000 births. Regarding the prevention of fetal death in the general population, it is not recommended to counsel for rest and not to prescribe vitamin A, vitamin D nor micronutrient supplementation for the sole purpose of reducing the risk of fetal death (Weak recommendations; Low quality of evidence). It is not recommended to prescribe aspirin (Weak recommendation; Very low quality of evidence). It is recommended to offer vaccination against influenza in epidemic periods and against SARS-CoV-2 (Strong recommendations; Low quality of evidence). It is not recommended to systematically look for nuchal cord encirclements during prenatal screening ultrasounds (Strong Recommendation; Low Quality of Evidence) and not to perform systematic antepartum monitoring by cardiotocography (Weak Recommendation; Very Low Quality of Evidence). It is not recommended to ask women to perform an active fetal movement count to reduce the risk of fetal death (Strong Recommendation; High Quality of Evidence). Regarding evaluation in the event of fetal death, it is suggested that an external fetal examination be systematically offered (Expert opinion). It is recommended that a fetopathological and anatomopathological examination of the placenta be carried out to participate in cause identification (Strong Recommendation. Moderate quality of evidence). It is recommended that chromosomal analysis by microarray testing be performed rather than conventional karyotype, in order to be able to identify a potentially causal anomaly more frequently (Strong Recommendation, moderate quality of evidence); to this end, it is suggested that postnatal sampling of the placental fetal surface for genetic purposes be preferred (Expert Opinion). It is suggested to test for antiphospholipid antibodies and systematically perform a Kleihauer test and a test for irregular agglutinins (Expert opinion). It is suggested to offer a summary consultation, with the aim of assessing the physical and psychological status of the parents, reporting the results, discussing the cause and providing information on monitoring for a subsequent pregnancy (Expert opinion). Regarding announcement and support, it is suggested to announce fetal death without ambiguity, using simple words and adapting to each situation, and then to support couples with empathy in the various stages of their care (Expert opinion). Regarding management, it is suggested that, in the absence of a situation at risk of disseminated intravascular coagulation or maternal vitality, the patient's wishes should be taken into account when determining the time between the diagnosis of fetal death and induction of birth. Returning home is possible if it's the patient wish (Expert opinion). In all situations excluding maternal life-threatening emergencies, the preferred mode of delivery is vaginal delivery, regardless the history of cesarean section(s) history (Expert opinion). In the event of fetal death, it is recommended that mifepristone 200mg be prescribed at least 24hours before induction, to reduce the delay between induction and delivery (Low recommendation. Low quality of evidence). There are insufficient data in the literature to make a recommendation regarding the route of administration (vaginal or oral) of misoprostol, neither the type of prostaglandin to reduce induction-delivery time or maternal morbidity. It is suggested that perimedullary analgesia be introduced at the start of induction if the patient asks, regardless of gestational age. It is suggested to prescribe cabergoline immediately in the postpartum period in order to avoid lactation, whatever the gestational age, after discussing the side effects of the treatment with the patient (Expert opinion). The risk of recurrence of fetal death after unexplained fetal death does not appear to be increased in subsequent pregnancies, and data from the literature are insufficient to make a recommendation on the prescription of aspirin. In the event of a history of fetal death due to vascular issues, low-dose aspirin is recommended to reduce perinatal morbidity, and should not be combined with heparin therapy (Low recommendation, very low quality of evidence). It is suggested not to recommend an optimal delay before initiating another pregnancy just because of the history of fetal death. It is suggested that the woman and co-parent be informed of the possibility of psychological support. Fetal heart rate monitoring is not indicated solely because of a history of fetal death. It is suggested that delivery not be systematically induced. However, induction can be considered depending on the context and parental request. The gestational age will be discussed, taking into account the benefits and risks, especially before 39 weeks. If a cause of fetal death is identified, management will be adapted on a case-by-case basis (expert opinion). In the event of fetal death occurring in a twin pregnancy, it is suggested that the surviving twin be evaluated as soon as the diagnosis of fetal death is made. In the case of dichorionic pregnancy, it is suggested to offer ultrasound monitoring on a monthly basis. It is suggested not to deliver prematurely following fetal death of a twin. If fetal death occurs in a monochorionic twin pregnancy, it is suggested to contact the referral competence center, in order to urgently look for signs of acute fetal anemia on ultrasound in the surviving twin, and to carry out weekly ultrasound monitoring for the first month. It is suggested not to induce birth immediately., (Copyright © 2024 The Authors. Published by Elsevier Masson SAS.. All rights reserved.)

The objective was to review the existing literature reporting on spontaneous abortion (SA) and intrauterine fetal demise (IUFD) associated with cytomegalovirus (CMV) infection. A review using standardized terminology such as 'intrauterine fetal death', 'congenital cytomegalovirus' and 'CMV' was performed using PubMed and Embase (Medline) using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology. Twenty-one studies met inclusion criteria. CMV was identified as a potential or likely factor in a median of 7.1% of SA or IUFD in study cohorts. Of the studies, 11 used fetal remains, 18 used placenta, 6 used serum, and 1 used post-mortem dried blood spot as specimens for testing for CMV. Features commonly observed were fetal thrombotic vasculopathy, hydrops fetalis and chronic villitis. CMV is frequently noted in studies evaluating viral etiologies of SA or IUFD. Large population-based studies are needed to estimate the incidence of CMV-associated SA or IUFD. CMV and congenital CMV should be included on the differential diagnosis in all cases of SA or IUFD of unknown etiology.

Objective: To analyze the temporal trend of fetal mortality and its components, of avoidable and ill-defined causes according to two avoidability classifications in Recife, Pernambuco, 2010-2021., Method: Ecological study of temporal trends of fetal mortality in Recife, 2010-2021. The Brazilian List of Avoidable Causes of Death for fetal deaths (LBE-OF) and Brazilian List of Avoidable Causes of Death for children under five years of age (LBE < 5) were used. The Joinpoint regression model was applied to analyze the temporal trends., Results: Trends in fetal mortality and its components were stationary. The group of avoidable causes presented higher mortality rates in both classifications, with an increasing trend according to the LBE-OF (Annual Percentage Change-APC: 2,1; p = 0,018) and stationary according to the LBE < 5. There was a decreasing trend in mortality from ill-defined causes only according to the LBE-OF (APC: -12,3; p < 0,001)., Conclusion: The results showed the stagnation of the temporal trend in fetal mortality, the avoidability of most deaths, and the potential of LBE-OF in monitoring the quality of information on the basic causes and avoidability of fetal deaths.

AhR knockout mice are not completely infertile; however, they do experience decreased litter sizes after repeated pregnancies. This study revealed that the decrease in the number of live births is partly due to fetal deaths leading to miscarriages. Interestingly, fetal mortality was found to be linked only to maternal AhR gene defects and not the fetal genotype. Furthermore, we observed no significant changes in litter sizes in allogenic pregnancy, where AhR-KO female mice were crossed with ICR male mice. The results indicated that the absence of AhR in the dams affected the expression of immune tolerance-related genes in both the placenta and fetus. Specifically, FoxP3 and indoleamine 2,3-dioxygenase-1 (IDO1) mRNA levels were lower in the placentas of AhR-KO dams than in those of wild-type dams. Moreover, there were elevated levels of IL-1β and IFN-γ mRNA in the placentas of the AhR-KO dams, which indicated increased inflammation. However, the mRNA expression levels of IL-6 and IDO1 were low despite the elevated mRNA levels of IL-1β and IFN-γ, which may be because AhR is directly involved in IL-6 and IDO1 transcription. These findings imply that in AhR-KO mice, fetal death may be attributed to the disturbance of fetal-maternal immune tolerance as a result of increased inflammation and reduced IDO1 and FoxP3 mRNA levels., Competing Interests: Declaration of Competing Interest The authors declare that they have no conflict of interest., (Copyright © 2024 The Authors.

Objective: To explore seizure control and offspring outcomes associated with antiseizure medication (ASM) withdrawal during the first trimester of pregnancy., Methods: Based on a prospective multicenter study in China, pregnancies followed up between 2009 and 2023 at the neurology outpatient clinic of 50 hospitals were included in this study. Information on demographics, epileptic characteristics, treatment during pregnancy, and offspring outcomes was collected. Pregnancies were categorized into an ASM withdrawal group and an ASM continuation group. Balance tests and univariate log-binomial regression analysis were conducted to identify imbalanced factors between groups and potential risk factors for seizure deterioration during pregnancy. Multivariate log-binomial regression was then used to estimate the adjusted effects of ASM withdrawal on seizure deterioration during pregnancy and fetal outcomes. In addition, exploratory subgroup analysis was conducted to identify high-risk patients who should avoid ASM withdrawal., Results: Of the 695 pregnancies enrolled, 14.2% withdrew ASMs in the first trimester of pregnancy. ASM withdrawal during this period was associated with a risk of seizure deterioration during pregnancy (adjusted risk ratio [aRR] 1.405, 95% confidence interval [CI] 1.009-1.876). Subgroup analysis revealed a significant risk of seizure deterioration in pregnancies with seizures in 9 months (aRR 1.590, 95% CI 1.079-2.344). After adjusting the folic acid dose, no evidence of protective effects on fetus after ASM withdrawal was observed compared to patients with continued treatment, whereas seizure deterioration during pregnancy increased the risk of fetal death (aRR 3.577, 95% CI 1.086-11.651)., Significance: ASM withdrawal in the first trimester of pregnancy did not show a protective effect on fetal outcomes but rather resulted in increased seizure frequency during pregnancy. However, this finding requires a larger sample for validation. Furthermore, seizure deterioration during pregnancy was associated with an increased risk of fetal death., (© 2024 International League Against Epilepsy.)

Objectives: In 2019, Quebec changed its stillbirth definition to include fetal deaths at 20 weeks gestation or more. Previously, the criterion was a minimum birth weight of 500 g. We assessed the impact of the new definition on stillbirth rates., Methods: We conducted a retrospective study of stillbirth rates between 2010 and 2021 in Quebec. The exposure consisted of the period during the new definition versus the preceding period. We assessed how the new definition affected stillbirth rates using interrupted time series regression, and compared the period during the new definition with the preceding period using prevalence differences and prevalence ratios with 95% confidence intervals (CI). We determined the extent to which fetuses at the limit of viability (under 500 g or 20‒23 weeks) accounted for any increase in rates., Results: Stillbirth rates went from 4.11 before the new definition to 6.76 per 1000 total births immediately after. Overall, the change in definition led to an absolute increase of 2.58 stillbirths per 1000 total births, for a prevalence ratio of 1.76 (95% CI 1.61‒1.92) compared with the preceding period. Fetal deaths due to congenital anomalies increased by 6.82 per 10,000 (95% CI 4.85‒8.78), while deaths due to pregnancy termination increased by 10.47 per 10,000 (95% CI 8.04‒12.89). Once the definition changed, 37% of stillbirths were under 500 g and 42% were between 20 and 23 weeks, with around half of these caused by congenital anomalies and terminations., Conclusion: Stillbirth rates increased after the definition changed in Quebec, mainly due to congenital anomalies and pregnancy terminations., (© 2024.

Introduction: Antiphospholipid syndrome (APS) is a cause of pregnancy morbidity. We aim to determine the frequency of criteria and non-criteria anti-phospholipid (aPL) autoantibodies in patients admitted for unexplained fetal death (UFD), pre-eclampsia (PE) and/or fetal growth restriction (FGR)., Methods: All consecutive patients with UFD, PE and/or FGR followed in the department of Obstetrics, Bichat Hospital, University of Paris, Paris, between January 2019 and December 2021 were screened. Patients with available serum stored from the index pregnancy were included. Patients with previously known APS or twin pregnancy were excluded. Testing for aPL autoantibodies included anti-cardiolipin (aCL), anti-β2GPI (aβ2GPI), anti-phosphatidylethanolamine (aPE), anti-phosphatidylserine/prothrombin (aPS/PT) IgG/IgM and anti-annexin V IgG. When available, placenta specimens were analyzed by a pathologist blinded to the aPL status. All clinical characteristics, pregnancy features, and comorbidities were extracted from electronic medical records., Results: Overall 167 (32 (28.8-35.7) years) patients with UFD (n = 28; 16.8 %), PE (n = 60; 35.9 %) and/or FGR (n = 105; 62.9 %) were screened for aPL autoantibodies. Moderate titers of aPL autoantibodies were detected in 33 (n = 33/167, 19.8 %) patients. aPL autoantibodies were non-criteria aPE IgG/IgM in most cases (n = 28/33, 84.8 %). aPS/PT IgG/IgM were found in 11 (n = 11/33, 33.3 %) cases and aCL or aβ2GP1 IgG/IgM in 4 (n = 4/33, 12.1 %). Multivariable logistic regression showed that aPL autoantibodies were mostly associated with UFD (OR 4.37 [1.72-11.20], p = 0.002), PE ≤ 34th week of gestation (3.22 [0.86-11.90], p = 0.070) and chronic deciduitis (8.03 [0.89-67.2], p = 0.060) DISCUSSION: The frequency of aPL autoantibodies, mostly aPE, is high in patients with late pregnancy morbidity and may qualify obstetrical APS., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.
