To compare characteristics of labor, cardiotocography traces, and maternal and neonatal outcomes, in a cohort of pregnancies at term complicated by maternal intrapartum pyrexia, with or without a histologic diagnosis of chorioamnionitis. This is a retrospective case-control study including pregnancies at term with detection of maternal intrapartum pyrexia, delivered between January 2020 and June 2021. Cardiotocography traces were entirely evaluated, since admission till delivery, and classified according to the International Federation of Obstetrics and Gynecology (FIGO) guideline. Maternal and neonatal outcomes were also recorded as secondary outcomes. Placentas have been studied according to the Amniotic Fluid Infection Nosology Committee. Forty four patients met the inclusion criteria and were included in the study cohort. There was a significant association between the use of oxytocin augmentation in labor and the histologic diagnosis of chorioamnionitis. A significative recurrence of loss and/or absence of accelerations at the point of pyrexia was also documented in women with histological chorioamnionitis compared to the others. Chorioamnionitis appears to be associated with myometrial disfunction, as suggested by the increased use of oxytocin augmentation during active labor of women at term with intrapartum pyrexia and histologic diagnosis of chorioamnionitis.

Maternal Graves' autoantibodies are well known to cause fetal and neonatal thyroid disturbances. Despite radioiodine therapy, Graves' autoantibodies are known to persist, which can cross the placenta and cause hyperthyroidism in the fetus. We present the case of a 26-year-old woman in her first pregnancy, clinically and biochemically euthyroid with history of treated Graves' disease, where the fetus showed signs of hyperthyroidism on antenatal scans. This was confirmed by amniotic fluid testing as fetal blood sampling was not feasible and successfully treated with maternal carbimazole whilst continuing thyroxine for the mother (block-replacement). We discuss the challenges in the diagnosis of fetal hyperthyroidism and treatment whilst maternal thyroid status is maintained on thyroxine. [ABSTRACT FROM AUTHOR]

Background: Ultrasound serves as a valuable tool for the early detection of fetal bowel dilatation, yet the correlation between fetal bowel dilatation and gastrointestinal malformations remains to be further investigated. This study aims to explore the relationship by conducting a follow-up and analysis of fetuses with bowel dilation. Methods: A retrospective analysis was conducted on 113 fetuses with bowel dilatation at our center from July 2014 to December 2019. The location and degree of bowel dilatation were analyzed. ROC curves were constructed based on the diameter of the bowel and its ratio to fetal gestational age. Results: In total, 40 of 41 cases (97.6%) with upper gastrointestinal dilatation (double-bubble sign) and 46 of 72 cases (63.9%) with lower gastrointestinal dilatation were diagnosed with gastrointestinal malformations postnatally. The AUC of the dilatation diameter was 0.854 with a cutoff value of 18.05 mm in patients with lower gastrointestinal dilatation. The ratio of the diameter to gestational age (D/GA) showed a higher AUC of 0.906 with a cutoff value of 0.4931. Conclusions: The presence of the double-bubble sign in fetuses indicates a close association with duodenal obstruction. The risk of gastrointestinal malformations increases when the bowel diameter exceeds 18.05 mm, particularly when the D/GA surpasses 0.4931. [ABSTRACT FROM AUTHOR]

Objective: Fetal urinary tract dilatation (UTD) is one of the common fetal problems with remarkable difficulties in diagnosis and management in the antenatal and postnatal periods. This study aimed to determine the value of Doppler ultrasound assessment of the renal arteries in fetuses with ureteropelvic junction type hydronephrosis (UPJO) for the prediction of neonatal outcomes of infants. Materials and Methods: Fetal renal artery Doppler values were evaluated in pregnant women between 28-32 weeks. Measurements were taken for Doppler values and the fetal obstruction and were classified through the utilization of UTD classification. Based on postnatal ultrasound, these infants were grouped by UTD classification. Results: There was a statistically significant difference between the left renal artery Systolic/Diastolic (S/D) Ratio and bilateral renal artery Peak Systolic Velocity (PSV) values of the control and patient groups, (p<0.05). PSV values were higher in the patient group. The difference between the pulsality index, resistive index, and right renal artery S/D values of the control and patient groups was not statistically significant (p>0.05). Conclusion: Fetal renal artery Doppler is not effective in predicting the degree of hydronephrosis and renal damage in postnatal follow-up of fetuses with a diagnosis of UPJO. [ABSTRACT FROM AUTHOR]

OBJECTIVES: Electronic fetal monitoring (EFM) is used to identify early signs of fetal deterioration. However, caution is advised when interpreting cardiotocographic parameters. A promising alternative is umbilical cord blood sampling. The analysis of blood gases and lactate levels in the cord within the initial minutes of life is a recommended approach. STUDY DESIGN: This prospective cohort study, conducted over eighteen months from June 2021 to December 2022, enrolled 70 patients with non-reactive and 70 with reactive cardiotocograph (CTG) patterns. APGAR scores were recorded at 1 and 5-minute intervals. 1 ml of umbilical artery blood was assessed in an arterial blood gas machine and fetal acidosis was defined as pH <7.0 and a lactate concentration exceeding 4 mmol/L. RESULTS: In the non-reactive CTG group, 35.7% had early decelerations, 37.1% had variable decelerations, and 17.1% had late decelerations (p<0.001). The mean cord blood lactate was 5.220±1.970 mmol/L in the non-reactive CTG group and 3.400±0.228 mmol/L in the reactive CTG group. Similarly, the mean cord blood pH was 7.030±0.007 in the non-reactive CTG group and 7.170±0.076 in the reactive CTG group (p<0.001). 14.3% of cases in the non-reactive CTG group had a 5-minute APGAR <7, with a higher APGAR score in the reactive group. CONCLUSION: The study suggests that abnormal or indeterminate CTG readings are linked to a higher risk of intrapartum fetal acidosis. Non-reactive CTG results were associated with higher mean cord blood lactate and pH levels and more number of Neonatal Intensive Care Unit (NICU) admissions. There is a definite correlation between abnormal CTG patterns and poorer neonatal outcomes. [ABSTRACT FROM AUTHOR]

Introduction: Saving Babies' Lives Care Bundle Version 2 highlights the importance of correct identification and reporting of echogenic bowel to improve maternal and newborn outcomes. Yet there is no national consensus to guide sonographers in identifying and reporting fetal echogenic bowel. This two-phase study aims to develop a national consensus to guide sonographers on the identification, classification and reporting of fetal echogenic bowel during the Fetal Anomaly Screening Programme (FASP) second trimester anomaly scan. Phase 1 results are presented capturing the national current practice of sonographers in its identification. Methods: An online questionnaire survey was deployed to capture numerical and free text data. Data analysis was by descriptive statistics. Participants were recruited via social media and through professional networks and organisations. Results: A total of 95 participants completed the questionnaire during an 11-week period. Common practice across England included sonographers using a subjective method for identifying fetal echogenic bowel and making comparisons to fetal bone. However, there was wide variance in the fetal bone used and the transducer frequency typically used to assess bowel echogenicity. Confirmation of echogenic bowel was made at the 20-week scan in 58% of cases, 32% following fetal medicine department review with the remaining 10% unsure when confirmation occurred. Conclusion: While there is common practice in identifying and report echogenic fetal bowel in some areas, there remains disparity within sonographer practice in England's national screening service. This study allowed baseline data to be collated, providing the first steps towards development of guidance for sonographers in identifying and reporting this appearance. [ABSTRACT FROM AUTHOR]

Introduction: Decisions about the management of infants exposed to maternal chorioamnionitis are often based on estimates of the risk of infection determined by a neonatal early onset sepsis risk calculator (NEOSC). Such management, however, results in drawing blood from and starting intravenous lines on many healthy infants. In some institutions, it also results in separating them from their families for treatment in the neonatal intensive care unit (NICU). Our practice for many years has been to do laboratory studies and give antibiotics to chorioamnionitis-exposed (CE) infants only if they show signs of infection. Using this approach, we have evaluated and treated far fewer infants than we would have if we had used the NEOSC. We reviewed our experience over five years to document the differences in patient management and to identify adverse outcomes in these infants. Methods: Charts of CE infants ≥ 35 weeks EGA (estimated gestational age) were reviewed over a 5-year period in 2012 when our institution converted to electronic medical records. Data collected included vital signs, laboratory results, NICU admission, antibiotic treatment, and hospital readmission during the first week after discharge. Their mothers' charts were reviewed for data needed to complete the NEOSC. The number of infants who underwent laboratory evaluations and treatment with antibiotics was compared to the number who would have had such evaluations and treatment according to NEOSC recommendations. Results: We treated 126 (16%) of 768 CE infants with antibiotics vs. 216 (28%) who would have been treated according to the NEOSC recommendations. Another 17 patients had blood cultures but were not treated with antibiotics. None of the untreated infants became ill, had positive blood cultures, were admitted to the NICU, or were readmitted to the hospital within the first week after discharge. Conclusion: CE infants were managed safely in our institution based only on clinical signs of infection. If multicenter studies corroborate our experience, revised recommendations could markedly reduce the number of CE infants evaluated and treated with antibiotics. [ABSTRACT FROM AUTHOR]

Elastography is considered a novel technique in the assessment of placenta parenchymal elasticity and very few data present the feasibility of elastography on human fetal tissue. This study aims to investigate the feasibility of fetal liver and placenta elastography and differences in pregnancies with GDM. Fifty-five women with GDM and 40 women with uncomplicated pregnancy as the control group was enrolled prospectively in this case-control study. Fetal liver VTIQ and placenta VTIQ elastography were performed between 25 and 39 weeks of pregnancy. Mean placenta thickness at the level of umbilical cord insertion was significantly higher in the GDM group than in the control group (p=0.034). VTIQ elastography elasticity velocity (kPa) examinations revealed similar mean placenta and mean fetal liver stiffness in both groups. A weak to moderate correlation was observed between the mean elasticity of the placenta and the mean elasticity of the fetal liver (r=0.310; p=0.004). Elastography may provide valuable information of especially on fetal tissue development and pathology. While placenta and fetal liver VTIQ elastography are feasible in pregnancy, the diagnostic value of these examinations in GDM is not certain and it seems to be that significant differences in SWE examinations that reflect structural changes in fetal tissue or placenta are more prominent in more chronic conditions such as type 1 and type 2 diabetes mellitus.

Mucopolysaccharidosis (MPS)‐VII, called Sly disease, is a lysosomal storage disorder that can cause fetal hydrops, including fetal hydrothorax (FHT). We describe two fetal cases that received thoracoamniotic shunting for FHT, which was later found to be associated with MPS‐VII by exome sequencing. Bilateral FHT accompanied by skin edema and ascites was found before 20 weeks of gestation in both cases. One fetus died in utero at 35 weeks of gestation, and the other survived with preterm delivery at 30 weeks of gestation. Both cases inherited compound pathogenic variants of GUSB from parents. Comparison with previously reported primary FHT cases revealed distinct clinical features in MPS‐VII‐associated FHT: early gestational age at diagnosis (<26 weeks), bilateral effusion, skin edema with ascites, and poor survival. A genetic analysis would be considered for FHT cases, with consideration of shunting when they show early‐onset bilateral effusions with skin edema and ascites. [ABSTRACT FROM AUTHOR]

Objectives: Unconjugated estriol (uE3) is used as a marker for fetal aneuploidy in maternal serum screening tests. The goal of this study was to examine the validity of a new immunoassay for uE3 that uses a monoclonal antibody (m-uE3) rather than the more commonly used polyclonal antibody (p-uE3). Setting: Assays were performed in the Special Chemistry laboratory at Women and Infants Hospital of Rhode Island. Methods: Residual fresh (n = 100) and frozen (n = 533) second trimester serum samples from routine clinical care were tested using p-uE3 and/or m-uE3 assays. Assay results were compared between methods using Bland–Altman plots. A median equation was developed for m-uE3 results. Down syndrome risks were compared between the two assays in a case–control sample set (21 cases each matched with five controls for the completed week of gestation, duration of freezer storage and race). Results: Log-transformed serum uE3 levels were highly correlated between the assays (r = 0.93, p < 0.001), with the m-uE3 assay levels yielding, on average, 23% higher (standard deviation of differences in log uE3 concentrations = 0.07) results. Assay and gestation-based median equations were calculated and used to convert m-uE3 concentrations to multiples of the median (MoM). The m-uE3 MoM values fit a log Gaussian distribution well with a log standard deviation of 0.11. Down syndrome risk results were not significantly different between assays. Conclusions: The m-uE3 assay, with results expressed in MoMs, is suitable for screening and as a monoclonal-based assay offers the advantage of a predictable and indefinite supply of antibody to perform the assay.

Although nearly all noninvasive prenatal testing is currently based on analyzing circulating maternal cell-free DNA, the technical methods usedvary considerably. We review the different methods. Based on validation trials and clinical experience, there are mostly relatively small differences in screening performance for trisomies 21, 18, and 13 in singleton pregnancies. Recent reports show low no-call rates for all methods, diminishing its importance when choosing a laboratory. However, method can be an important consideration for twin pregnancies, screening for sex chromosome abnormalities, microdeletion syndromes, triploidy, molar pregnancies, rare autosomal trisomies, and segmental imbalances, and detecting maternal chromosome abnormalities.

Considering the diagnostic limitations of cfDNA-based noninvasive prenatal testing (NIPT), scientists have long been interested in isolating and analyzing rare intact fetal and trophoblast cells from maternal blood or endocervical samples to diagnose fetal genetic conditions. These cells may be scarce and difficult to isolate, but they are a direct source of pure fetal genetic material. In this review, we summarize the history of cell-based NIPT, present an updated review on its current developments, evaluate its genetic diagnostic potential, and discuss its future prospects for clinical use.

Aims: The aim of this study was to evaluate the association of a low cerebroplacental ratio (CPR) with hypoxic ischaemic encephalopathy (HIE), severe neonatal morbidity (SNM) and perinatal mortality (PNM). Methods: This was a retrospective cohort study of late‐preterm and term births at Mater Mothers' Hospital, Brisbane, between 2016 and 2020. Study outcomes were HIE, PNM and SNM (a composite of severe acidosis, Apgar score less than four at 5 min, severe respiratory distress or need for significant cardiopulmonary resuscitation at birth). Univariate and multivariable logistic regressions were used to determine if a low CPR was associated with HIE, SNM or PNM. Results: A total of 51 870 births met the inclusion criteria. Of these, 216 (0.42%) were complicated by HIE, 10 224 (19.7%) had SNM and 251 (0.48%) had PNM. Rates of low CPR (<10th and <5th centile) were significantly higher in the SNM cohort (20.1 and 13.2%, respectively) and PNM cohort (21.1 and 15.1%, respectively) compared to the overall cohort. A low CPR was associated with significantly increased adjusted odds for SNM but not for HIE or PNM. The area under the receiver operating characteristic curve for CPR <10th centile was greatest for SNM (0.768) and lowest for HIE (0.595). Predictive margins of a low CPR for HIE, SNM and PNM were significant only for SNM at late‐preterm gestations. Conclusions: A low CPR is associated with increased odds of SNM in infants born >34 weeks' gestation but not for HIE or PNM. [ABSTRACT FROM AUTHOR]

The article presents the results of a study amniotic glucose concentration as a potential early indicator of the inflammatory process in the fetal membranes. The main focus was on the analysis of the features of pregnancy and labor in women with premature rupture of membranes (PROM) during full-term and preterm labor according to amniotic fluid glucose levels. Currently, the expectant approach in cases of PROM is widely practiced throughout the world. The objective: to estimate the glucose level in the amniotic fluid as a preclinical marker of chorioamnionitis. Materials and methods. Depending on the glucose concentration in the amniotic fluid at the time of rupture of membranes and the term of rupture of membranes, 97 pregnant women were divided into 4 groups. I and II groups consisted of women with PROM between 24 and 36 weeks and 6 days. In the I group there were 34 pregnant women with a glucose concentration in the amniotic fluid of more than 0.5 mmol/l, and in the II group – 15 pregnant women with the indicator of less than 0.5 mmol/l. III and IV groups included pregnant women with PROM at full-term pregnancy (after 37 weeks). In the III group there were 34 patients with an amniotic glucose concentration of more than 0.5 mmol/l, and in the IV – 14 pregnant women with the indicator of less than 0.5 mmol/l. In all groups, the further course of pregnancy, the time period from the rupture of membranes to the beginning of labor, the need for induction of labor, hyperthermia before the beginning of labor, deviations from the normal course of labor were analyzed (hyperthermia, fetal distress in labor, uterine weakness) and the frequency of operative delivery. Results. The study determined that women with an amniotic glucose concentration below 0.5 mmol/l at the time of hospitalization were more likely to have hyperthermia before and during childbirth. Hyperthermia was most often observed during the first 12 hours after membrane rupture. In addition, these women were more prone to serious birth complications, such as fetal distress, weak labor, and a greater likelihood of needing an operative delivery. Conclusions. 1. A decreased amniotic glucose level less than 0.5 mmol/l is associated with more frequent clinical manifestations of amniotic infection (20% in preterm pregnancies and 14.8% – in full-term pregnancies) than in groups with a glucose content of more than 0.5 mmol/l (8.8% in preterm pregnancies and 5.9% – in full-term pregnancies, p≤0.05). 2. Among patients with a glucose content in amniotic fluid less than 0.5 mmol/l, laboratory manifestations of intra-amniotic infection were detected more often (40% in preterm pregnancies and 42.5% in full-term pregnancies) than among pregnant women with a glucose content of more than 0.5 mmol/l (20% in both full-term and preterm pregnancies, p≤0.05). 3. Determination of the glucose level in amniotic fluid can be considered as an available method of preclinical diagnosis of chorioamnionitis for the individual choice of management tactics in case of premature rupture of the amniotic membranes, which is especially important in premature pregnancy.

This case report presents the first registered patient in Latvia with type 0 spinal muscular atrophy (SMA). During the first-trimester ultrasonography of the unborn patient, an increased thickness of the nuchal fold was detected. The mother reported decreased foetal movements during the pregnancy. After the boy was born, his general condition was extremely severe. The clinical signs indicated a suspected neuromuscular disorder. A precise diagnosis, type 0 SMA, was determined 7 days after birth through a newborn pilot-screening for SMA, which was conducted for all newborns whose parents consented to participate. The condition of the infant deteriorated. He had severe respiratory distress followed by multiple events leading to his death. Currently, there are only a few published case reports detailing an increased nuchal translucency (NT) measurement in association with a diagnosis of SMA in the foetus. However, an increased NT measurement is a clinically relevant sign as it can be related to genetic syndromes, foetal malformations, disruptions, and dysplasias. Since there is no cure for infants with type 0 SMA at present, it is crucial to be able to detect this disease prenatally in order to provide the best possible care for the patient and parents. This includes the provision of palliative care for the patient, among other measures. This case report highlights the prenatal signs and symptoms in relation to type 0 SMA. [ABSTRACT FROM AUTHOR]

The gallbladder is not part of the standard survey of a fetus during obstetrical ultrasound. Yet, some anomalies can be detected. Most are clinically benign, but some are features of or associated with more serious complications. Biliary atresia constitutes the diagnosis with the worst prognosis. Its in utero diagnosis is difficult. Still, markers do exist and should be searched for. Knowledge of the normal appearances, variants and abnormalities of the gallbladder contributes to proper management. Any suspicion should lead to meticulous postnatal workup. Pre- or postnatal magnetic resonance imaging can provide additional information in select cases. [ABSTRACT FROM AUTHOR]

Congenital uropathies are the most common fetal anomalies. They include a wide spectrum of anomalies ranging from mild pelvis dilation to complex urinary tract malformations. Prenatal imaging not only allows for their diagnosis but, in experienced hands, it can differentiate obstructive from refluxing or malformative uropathies. Such precise prenatal information allows for intervention before birth in select cases or for adapting the postnatal workup to provide a better long-term outcome. For the different types of congenital uropathies, we describe their prenatal presentations on US and the complementary role of fetal MRI where indicated. We correlate these findings with postnatal workup and summarize the updated neonatal diagnostic and clinical/surgical management. [ABSTRACT FROM AUTHOR]

Objective: To determine whether usage of the Neonatal Early-Onset Sepsis (EOS) Calculator decreases sepsis evaluations, antibiotic administration, length of stay (LOS), and resource utilization when caring for newborns whose mothers were diagnosed with confirmed chorioamnionitis (CAM). Study Design: This retrospective cohort study enrolled 236 dyads of mothers and newborns (= 35 weeks gestation). De-identified data, including newborn antibiotic usage, complete blood counts (CBC), blood cultures, and LOS, were collected one year before and after the 2019 implementation of the EOS calculator. To summarize the data for all study variables, descriptive statistics were utilized. All categorical variables were compared using the Fisher exact or X2 test, and the Wilcoxon Rank Sum test was applied for continuous variables. Results: A significant reduction was seen in the incidence of sepsis evaluations (P < 0.001) and antibiotic use (P < 0.001) after the implementation of the EOS calculator. An Arizona Medicare reimbursement rate estimation revealed that the median expense of EOS-related care decreased by $257.89 in infants whose mothers were diagnosed with confirmed CAM (P < 0.0001). Conclusion: The frequency of sepsis evaluations and antibiotic utilization in newborns of mothers diagnosed with confirmed CAM was significantly reduced with the use of the EOS calculator, resulting in decreased resource utilization.

Pyelectasis, also known as renal pelvic dilatation or hydronephrosis, is frequently found on fetal ultrasound. This study correlated prenatally-detected, moderate pyelectasis with postnatal outcomes. This retrospective, observational study was conducted at a tertiary medical center in Israel. The study group consisted of 54 fetuses with prenatal diagnosis of pyelectasis on ultrasound scan during the second trimester, defined as anteroposterior renal pelvic diameter (APRPD) 6–9.9 mm. Long-term postnatal outcomes and renal-related sequelae were obtained using medical records and telephone-based questionnaires. The control group included 98 cases with APRPD < 6 mm. Results indicate that fetal pyelectasis 6–9.9 mm was more frequent among males (68.5%) than females (51%, p = 0.034). We did not find significant correlations between 6–9.9 mm pyelectasis and other anomalies or chromosomal/genetic disorders. Pyelectasis resolved during the pregnancy in 15/54 (27.8%) cases. There was no change in 17/54 (31.5%) and 22/54 (40.7%) progressed to hydronephrosis Among the study group, 25/54 (46.3%) were diagnosed with neonatal hydronephrosis. There were more cases of renal reflux or renal obstruction in the study group compared to the control group 8/54 (14.8%) vs. 1/98 (1.0%), respectively; p = 0.002. In conclusion, most cases of 6–9.9 mm pyelectasis remained stable or resolved spontaneously during pregnancy. There was a higher rate of postnatal renal reflux and renal obstruction in this group; however, most did not require surgical intervention. [ABSTRACT FROM AUTHOR]

The purpose of this study is to explore risk factors of acute placental inflammatory lesions and the potential postnatal serum biomarkers for predicting the severity of intrauterine infection in preterm infants. We performed a retrospective analysis of premature infants with or without acute placental inflammatory lesions and their mothers by chart review for clinical data and placental histopathology. The preterm infants with acute placental inflammatory lesions had a higher rate of premature rupture of membranes (PROM), a longer duration of PROM, and a higher level of serum sialic acid (SIA) than those of the non-inflammation group (all p < 0.001). According to the different inflammatory histological structures, preterm infants with funisitis had a dominant longer duration of PROM than others (p < 0.05), and their gestational age was youngest among all the infants (p < 0.05). Furthermore, they had the highest content of serum SIA above other groups. The preterm infants in the acute histological chorioamnionitis group showed a similar trend of clinical manifestation and laboratory parameters with the funisitis group. Moreover, the closer the placental lesions were to the fetus, the lower the gestational age of preterm infants was, and the higher the serum SIA content was.
Conclusion: We utilized a simple and precise anatomically category method of placental inflammatory histopathology for pediatricians to distinguish the extent of fetal inflammatory response for representing early-onset infectious diseases of preterm infants. SIA might be one of the potential early-stage serum biomarkers to reflect the severe intrauterine infections and could guide the postnatal anti-infection treatment.What Is Known: • Acute placental inflammatory lesion contributes to preterm birth and a series of complications in preterm infants. • C-reactive protein and interleukin-6 in neonatal blood can be used as biomarkers for potential early-onset sepsis, but they are influenced by the postnatal physiological changes of preterm infants.What Is New: • The value of serum sialic acids of preterm infants within 1-hour afterbirth may be one of the rapid postnatal biomarkers for evaluating the severity of intra-amniotic infection. • The closer the placental lesions are to the fetus, the higher the content of serum sialic acid is.

Objective: To evaluate neonatal fever and adverse maternal and neonatal outcomes in febrile laboring women and assess whether the time interval between epidural analgesia (EA) administration and chorioamnionitis is associated with these complications.Methods: A retrospective cohort study at a university affiliated medical center between 2003 and 2015. Included were women who underwent term vaginal delivery attempt and diagnosed with chorioamnionitis. The primary outcomes compared between febrile women with and without EA were neonatal fever and adverse neonatal and maternal outcomes. The association between time from EA to fever (<6, 6-12, >12 h) and maternal and neonatal complications was also assessed.Results: During the study period, 1,933 women with chorioamnionitis were assessed. Of them, 1,810 (93.6%) received EA prior to fever and 123 (6.4%) febrile parturients did not receive EA. Neonatal fever and other neonatal adverse outcomes were similar in the EA vs. non-EA group (2.2% vs. 0.8% and 2.7% vs. 4.9% (NS)), except for transient tachypnea of the newborn rates which were lower in the EA group (1.4% vs. 4.1%, p = 0.043). Maternal complications were similar, besides for higher rates of instrumental deliveries found in the EA group (24.0% vs. 5.7%, p < 0.001). Time between EA and fever onset was not associated with neonatal complications in logistic regression analysis.Conclusion: Neonatal and maternal outcomes are similar in febrile laboring women with and without EA. The time interval between EA and onset of fever is not associated with increased rates of neonatal fever or adverse outcomes and should not affect the management of labor.

Objective: To evaluate the concentrations of calprotectin in amniotic fluid with respect to intra-amniotic inflammation and infection and to assess the presence or absence of bacteria in the amnio-chorionic niche with respect to presence or absence of intra-amniotic inflammation.Study Design: Seventy-nine women with singleton pregnancies and preterm labor with intact membranes (PTL) were included in the study. Amniotic fluid was collected at the time of admission by amniocentesis and calprotectin levels were analyzed from frozen/thawed samples using ELISA. Interleukin (IL)-6 concentration was measured by point-of-care test. Samples from amniotic fluid and the amnio-chorionic niche (space between amniotic and chorionic membranes) were microbiologically analyzed. Microbial invasion of the amniotic cavity (MIAC) was diagnosed based on a positive PCR result for Ureaplasma species, Mycoplasma hominis, 16S rRNA or positive culture. Intra-amniotic inflammation (IAI) was defined as amniotic fluid point-of-care IL-6 concentration ≥ 745 pg/mL. The cohort of included women was divided into 4 subgroups based on the presence or absence of IAI/MIAC; i) intra-amniotic infection, ii) sterile IAI, iii) intra-amniotic colonization and iv) neither MIAC nor IAI.Results: Women with intra-amniotic infection had a significantly higher intra-amniotic calprotectin concentration (median; 101.6 µg/mL) compared with women with sterile IAI (median; 9.2 µg/mL), women with intra-amniotic colonization (median; 2.6 µg/mL) and women with neither MIAC nor IAI (median 4.6 µg/mL) (p = 0.001). Moreover, significantly higher amniotic fluid calprotectin concentration was seen in women who delivered within 7 days (p = 0.003). A significant negative correlation was found between amniotic fluid calprotectin and gestational age at delivery (rho = 0.32, p = 0.003). Relatively more bacteria in the amnio-chorionic niche were found in the sterile IAI group compared with the other groups.Conclusions: Calprotectin concentrations in amniotic fluid were significantly higher in the intra-amniotic infection group compared with the other groups. Moreover, the bacterial presence in the amnio-chorionic niche was higher in IAI group. [ABSTRACT FROM AUTHOR]- Published

Background: Chorioamnionitis (CA) affects up to 3.9% of all deliveries worldwide and is one of the leading causes of early-onset neonatal sepsis. Fever≥380C is an essential criterion for the diagnosis of clinical CA. Obstetricians frequently take the maternal risk factors into consideration, and many mothers are treated as CA even with peak intrapartum temperature (PIT) between 37.60C to 37.90C if they have other clinical signs and risk factors.Aim: To estimate the prevalence of confirmed chorioamnionitis and adverse neonatal outcomes among those mothers with PIT below 380C.Materials and Methods: Retrospective chart review among mothers delivered at Al-Wakra Hospital, Qatar, between1stJanuary2016 to 31stDecember 2019 with a clinical suspicion of CA.Results: Among 21,471 mothers, 442 were suspected of having CA (2.06%, 95% CI 1.88 to 2.26%). After exclusions, 415 were included in the study, 203(48.9%) mothers had PIT between 37.6-37.90C. There was no significant difference in the rate of confirmed CA between the low (<380C) and higher (≥380C) temperature groups (25.4%Vs.31.3%, OR0.75, 95%CI0.46-1.25 , p.262). More patients in the low-temperature group received paracetamol for PIT between 37.6 to 37.9 0C, while it was less frequently used for such milder elevation in higher temperature group (88.2%Vs.38.9%, OR11.69, 95% CI 6.46-2.15, p <.001).Conclusion: The incidence of suspected clinical CA in our institution was within the international rates. Although nearly half of the mothers with suspected clinical CA had peak temperature below the recommended diagnostic criteria, the rate of confirmed CA and neonatal outcome was not significantly different from those with PIT≥380C. Early antipyretic use might have affected further elevation of temperature. [ABSTRACT FROM AUTHOR]- Published

Key content: Fetal cardiac arrhythmias are relatively common and account for up to 20% of referrals to fetal cardiologists.Arrhythmias may occur because of structural abnormalities of the fetal heart, or because of abnormal functioning of the cardiac conduction system in an otherwise structurally normal heart.Arrhythmias may be diagnosed using ultrasound and M‐mode and Doppler echocardiography.Transplacental therapy for tachyarrhythmias has been one of the success stories of fetal cardiology, and good outcomes can be expected in the absence of hydrops.Congenital heart block is most commonly caused by the transplacental passage of anti‐Ro and anti‐La antibodies and transplacental therapy is less successful in managing this. Learning objectives: To enable clinicians to provide better counselling for patients about the prognosis of fetal arrhythmias.To learn how to diagnose fetal arrhythmias and know when to refer to a specialist centre if the diagnosis is suspected.To understand the treatment options available and the evidence‐based antenatal care schedule.

Background: Fetal cerebral sinovenous thrombosis (CSVT) and dural sinus malformation (DSM) are rare types of fetal cerebral venous pathology that are becoming increasingly recognized as fetal imaging advances. Fetal DSMs are a common source of fetal CSVT, although CSVT may occur without a DSM. The literature on these disorders is limited.Methods: Cases of fetal CSVT and DSM were identified retrospectively through a query of the Indiana University Health fetal imaging archive from 2007 to 2021.Results: Seven cases were identified, all of whom were alive at birth. A DSM was present in six. Treatments after birth included enoxaparin sodium (3), embolization (3), and shunt placements (1). Five cases had documented regression or complete resolution of the thrombus and/or malformation. One was lost to follow-up, one died from complications of hydrocephalus at nine months, one was receiving physical and occupational therapy at last follow-up at three months, one had concern for autism and mild gait abnormality at 21 months, two had concern for speech delay (18 months and 24 months), and one had normal development at most recent follow-up (four years).Conclusions: Positive short-term outcomes may occur for some cases of fetal CSVT and DSM. However, risk factors and best treatments are not clear, and long-term outcome data are limited. There is a need for further study. [ABSTRACT FROM AUTHOR]- Published

Aim: To evaluate the diagnostic performance of three conventional clinical chorioamnionitis criteria; including Gibbs, Lencki, and suspected triple I; for the prediction of intra-amniotic infection.Methods: A retrospective cohort study was conducted using data from three perinatal centers from 2014 to 2018. Patients with preterm labor or premature prelabor rupture of membranes between 22 and 33 weeks of gestation and those who underwent transabdominal amniocentesis to detect intra-amniotic infection were selected. Intra-amniotic infection was defined as a positive amniotic fluid culture for microorganisms, including genital mycoplasmas, plus low glucose level or leukocytosis in amniotic fluid. Sensitivity, specificity, and positive and negative likelihood ratios were calculated to determine the diagnostic performance of each criterion in predicting intra-amniotic infection.Results: Of 99 pregnant women who met the study inclusion criteria, 13 (13.1%) had intra-amniotic infection confirmed by amniocentesis and 86 (86.9%) had no intra-amniotic infection. Maternal characteristics were not significantly different between groups, except for the higher incidence of preterm, prelabor rupture of membranes in pregnant women with intra-amniotic infection (53.8 versus 14%, p < .01). The incidences of clinical chorioamnionitis in the non-IAI and IAI groups were 1 of 86 (1.2%), 1 of 86 (1.2%), 0 of 86 (0%) and 2 of 13 (15.4%), 2 of 13 (15.4%), 2 of 13 (15.4%) according to Gibbs, Lenki, and suspected triple I criteria, respectively. The specificity of the three criteria ranged from 98.8 to 100%; however, the sensitivity was low (15.4%). The positive likelihood ratio was significant for three criteria from 13.2 (95% confidence interval [CI], 1.29-135) to infinite. However, the negative likelihood ratio was not low enough and not significant for the three criteria (0.85 [95% CI, 0.67-1.07] to 0.86 [95% CI, 0.68-1.08]).Conclusion: The conventional clinical chorioamnionitis criteria are not sensitive for the prediction of intra-amniotic infection in pregnant women with preterm labor and/or preterm prelabor rupture of membranes.

Aim: The importance of managing fetal arrhythmia has increased with advances in fetal echocardiography. We aimed to describe the incidence, types, clinical characteristics, treatments, and follow-ups of patients diagnosed with fetal arrhythmia in our center. Materials and Methods: Fetal echocardiographic examinations performed in our units between January 2016 and September 2019 were retrospectively evaluated. Fetal arrhythmias and their subtypes were identified using M-mode and Doppler echocardiography in all patients. Maternal age, gestational age, history of maternal or gestational pathology, diagnoses, and medications were recorded. Fetal arrhythmias were categorized into three main groups: 1) Irregular heart rhythm (ectopic beats), 2) Bradyarrhythmias: a ventricular rate less than 110 bpm; and 3) Tachyarrhythmias: a ventricular rate exceeding 180 bpm. Results: A total of 60 patients were diagnosed with fetal arrhythmia, corresponding to an overall incidence of 0.5%. The mean maternal and gestational age of those patients with fetal arrhythmia were 28.35±4.88 years and 31.03±5.94 weeks. One patient had maternal systemic disease, and four had concurrent congenital cardiac disease. Fetal tachycardia, bradycardia, and irregular heart rhythm were detected in 10 (16.6%), 8 (13.3%), and 42 (70%) patients, respectively. Conclusion: Fetal echocardiography represents the main diagnostic tool for prenatal evaluation of fetal arrhythmias, which have a variable prognosis depending on the type of arrhythmia. The most common fetal arrhythmia, the irregular heart rhythm, generally does not necessitate any treatment and resolves spontaneously. The treatment plan in patients should be based on etiology and fetal conditions. [ABSTRACT FROM AUTHOR]

Evaluate ultrasound diagnostic accuracy, maternal−fetal characteristics and outcomes in case of vasa previa diagnosed antenatally, postnatally or with spontaneous resolution before delivery. Monocentric retrospective study enrolling women with antenatal or postnatal diagnosis of vasa previa at Sant'Anna Hospital in Turin from 2007 to 2018. Vasa previa were defined as fetal vessels that lay 2 cm within the uterine internal os using 2D and Color Doppler transvaginal ultrasound. Diagnosis was confirmed at delivery and on histopathological exam. Vasa previa with spontaneous resolutions were defined as fetal vessels that migrate >2 cm from uterine internal os during scheduled ultrasound follow-ups in pregnancy. We enrolled 29 patients (incidence of 0.03%). Ultrasound antenatally diagnosed 25 vasa previa (five had a spontaneous resolution) while four were diagnosed postnatally, with an overall sensitivity of 96.2%, specificity of 100%, positive predictive value of 96.2%, and negative predictive value of 100%. Early gestational age at diagnosis is significally associate with spontaneously resolution (p 0.023; aOR 1.63; 95% IC 1.18–2.89). Nearly 93% of our patient had a risk factor for vasa previa: placenta previa at second trimester or low-lying placenta, bilobated placenta, succenturiate cotyledon, velametous cord insertion or assisted reproduction technologies. Maternal and fetal outcomes in case of vasa previa antenatally diagnosed are significally improved. Our data support the evaluation of umbilical cord insertion during routine second trimester ultrasound and a targeted screening for vasa previa in women with risk factor: it allows identification of fetus at high risk, reducing fetal mortality in otherwise healthy newborns.

Background: Conflicting statements by stakeholders in obstetric care have suggested different criteria for defining peripartum fever and suspected intraamniotic infection, which have not been evaluated. Methods: A case‐control study of pregnancies between 35 and 41 weeks at a single tertiary care center between January 2016 and December 2017. Cases with pathology‐confirmed chorioamnionitis were identified, and demographic data, risk factors, and neonatal outcomes were extracted from the medical record. The American College of Gynecology (ACOG) and National Institutes of Health (NIH) Workshop guidelines for identifying isolated maternal fever and suspected intraamniotic infection were applied, retrospectively. Odds ratios, sensitivity/specificity, and predictive value of each guideline for pathology‐confirmed chorioamnionitis and for secondary outcomes of interest were determined. Results: 943 mother‐infant dyads were evaluated including 41 (4.3%) with pathology‐confirmed chorioamnionitis. Among cases, 18 (43.9%) experienced any maternal temperature ≥38°C (100.4°F) with 12 (29.2%) and 8 (19.5%) cases meeting criteria for isolated maternal fever according to the ACOG and Workshop guidelines, respectively. Furthermore, the ACOG and Workshop guidelines correctly identified 6 (14.6%) and 3 (7.3%) of cases of pathology‐confirmed chorioamnionitis with high agreement between definitions (κ = 0.63). Laboratory evaluation, antimicrobial exposure, and prolonged length of stay in offspring are substantially higher in cases as compared to controls. Conclusions: Guidelines that rely on maternal fever definitions for the diagnosis of suspected intraamniotic infection exhibit high agreement with low sensitivity, but high specificity and negative predictive value for pathology‐confirmed chorioamnionitis. Maternal temperature ≥38°C continues to drive clinical decision‐making for both mother and offspring. [ABSTRACT FROM AUTHOR]

Objective This study aimed to assess whether colonization with group B streptococcus (GBS) is associated with maternal peripartum infection in an era of routine prophylaxis. Study Design This study presented a secondary analysis of women delivering ≥37 weeks who underwent a trial of labor from the U.S. Consortium on Safe Labor (CSL) study. The exposure was maternal GBS colonization and the outcome was a diagnosis of chorioamnionitis, and secondarily, analyses were restricted to deliveries not admitted in labor and measures of postpartum infection (postpartum fever, endometritis, and surgical site infection). Logistic regression with generalized estimating equations was used accounting for within-woman correlations. Models adjusted for maternal age, parity, race, prepregnancy body mass index, pregestational diabetes, insurance status, study site/region, year of delivery, number of vaginal exams from admission to delivery, and time (in hours) from admission to delivery. Results Among 170,804 assessed women, 33,877 (19.8%) were colonized with GBS and 5,172 (3.0%) were diagnosed with chorioamnionitis. While the frequency of GBS colonization did not vary by chorioamnionitis status (3.0% in both groups), in multivariable analyses, GBS colonization was associated with slightly lower odds of chorioamnionitis (adjusted odds ratio [AOR]: 0.89; 95% confidence interval [CI]: 0.83–0.96). In secondary analyses, this association held regardless of spontaneous labor on admission; and the odds of postpartum infectious outcomes were not higher with GBS colonization. Conclusion In contrast to historical data, GBS colonization was associated with lower odds of chorioamnionitis in an era of routine GBS screening and prophylaxis. Key Points Data in an era prior to routine group B streptococcus (GBS) screening and prophylaxis showed that maternal GBS colonization was associated with a higher frequency of maternal peripartum infection. In the current study, GBS colonization was associated with lower odds of chorioamnionitis in an era of routine GBS screening and prophylaxis. The results highlight potential benefits of GBS screening and intrapartum antibiotic prophylaxis beyond neonatal disease prevention, including mitigating the risk of maternal infectious morbidity.

Background: Preterm prelabor rupture of membranes (PPROM) is a major cause of morbidity and mortality for both the mother and the newborn. The vaginal germ profile in PPROM is poorly known, particularly regarding the risk of early-onset neonatal infection (EONI).Objective: To determine microbiological risk factors for EONI in case of PPROM before 34 weeks of gestation (WG).Study Design: A retrospective single-center cohort of patients with PPROM before 34 W G from 2008 to 2016. Vaginal swabs were obtained at admission and at delivery as per usual care and were analyzed by Gram stain and culture for vaginal dysbiosisi.e lactobacilli depletion and/or presence of potential pathogens.Results: Among 268 cases of PPROM, 39 neonates had EONI 14.55 %; (95 %CI 0.11 - 0.19) Overall, vaginal samples culture was positive in 16.67 % (95 %CI 11.95 %-22.32 %) at the time of rupture and 24.76 % (95 %CI 19.02 %-31.23 %) at delivery, with no significant differences between EONI and no-EONI groups (p = 0.797 and 0.486, respectively), including for Group B Streptococci (GBS) and Escherichia coli. EONI was significantly associated with dysbiosis at the time of rupture (23.94 % versus 10.35 % in the absence of dysbiosis, p = 0.009) and at delivery (19.70 % versus 3.90 % if no dysbiosis, p < 0.001). Clinical intra-uterine infection was present in 78.5 % (n = 31) of the EONI group versus 37.2 % (n = 85) in the non-EONI group (p < 0.001) and chorioamnionitis and/or funisitis were found in 97.3 % and 91.9 %, respectively in the EONI group, versus 56.11 % and 53.96 %, respectively, in the non-EONI group (p < 0.001).Conclusion: Dysbiosis following rupture and at delivery, but not the presence of pathogens in the VS culture, was associated with the risk of EONI in case of PPROM.

Objective: To assess the cardiotocographic changes and maternal and neonatal outcomes in cases of chorioamnionitis and or funisitis confirmed on histopathology.Study Design: A retrospective analysis of histopathology reports confirming chorioamnionitis and/or funisitis was carried out from 2014 to 2020 in a single centre. The preterm births (<37 weeks) were excluded. The maternal records were reviewed to determine the maternal and neonatal outcomes such as the mode of delivery, intrapartum and postpartum complications, umbilical cord arterial pH, and admission to the special care baby unit (SCBU). The CTG features were analysed on admission and during the intrapartum period. The study was approved by the Audit and Clinical Effectiveness department within the centre.Results: Out of the 57 cases of histologically confirmed chorioamnionitis and/or funisitis, 42 women (73.7 %) had intrapartum pyrexia and none of the mothers had an increased temperature at the point of fetal tachycardia (persistent increase in baseline fetal heart rate (FHR) by >10 % compared to the original baseline FHR). 43 (75.4 %) CTGs showed evidence of uterine tachysystole or hyperstimulation. 15 (26.3 %) cases had meconium stained amniotic fluid (MSAF). 54 (94.7 %) women had a caesarean section, and their babies were admitted to special care baby unit after delivery. 54 (94.7 %) babies had an umbilical artery of more than 7.1. 47 (87 %) of the women were readmitted with wound infection. All CTG traces showed a > 10 % increase in the baseline FHR and variable decelerations with overshoot were noted in cases where funisitis was confirmed in 25 cases (92.6 %). Loss of cycling was noted in 54 CTGs (94.7 %) and a sinusoidal pattern was identified in 27 (47.3 %).Conclusion: Rising (>10 %) baseline during labour along with loss of cycling with or without features of tachysystole or hyperstimulation should be considered in labour as features of ongoing chorioamnionitis. Chorioamnionitis confirmed on histopathology is associated with an increase in caesarean section rate due to fetal heart rate changes, increased risk of wound infection in mothers, and increased admission of the babies to SCBU.

FETAL heart rate monitoring , *FETAL monitoring , *DIAGNOSIS of fetal diseases , *STILLBIRTH , *FETAL death - Abstract
Background: Routine assessment in (near) term pregnancy is often inaccurate for the identification of fetuses who are mild to moderately compromised due to placental insufficiency and are at risk of adverse outcomes, especially when fetal size is seemingly within normal range for gestational age. Although biometric measurements and cardiotocography are frequently used, it is known that these techniques have low sensitivity and specificity. In clinical practice this diagnostic uncertainty results in considerable 'over treatment' of women with healthy fetuses whilst truly compromised fetuses remain unidentified. The CPR is the ratio of the umbilical artery pulsatility index over the middle cerebral artery pulsatility index. A low CPR reflects fetal redistribution and is thought to be indicative of placental insufficiency independent of actual fetal size, and a marker of adverse outcomes. Its utility as an indicator for delivery in women with reduced fetal movements (RFM) is unknown. The aim of this study is to assess whether expedited delivery of women with RFM identified as high risk on the basis of a low CPR improves neonatal outcomes. Secondary aims include childhood outcomes, maternal obstetric outcomes, and the predictive value of biomarkers for adverse outcomes.Methods: International multicentre cluster randomised trial of women with singleton pregnancies with RFM at term, randomised to either an open or concealed arm. Only women with an estimated fetal weight ≥ 10th centile, a fetus in cephalic presentation and normal cardiotocograph are eligible and after informed consent the CPR will be measured. Expedited delivery is recommended in women with a low CPR in the open arm. Women in the concealed arm will not have their CPR results revealed and will receive routine clinical care. The intended sample size based on the primary outcome is 2160 patients. The primary outcome is a composite of: stillbirth, neonatal mortality, Apgar score < 7 at 5 min, cord pH < 7.10, emergency delivery for fetal distress, and severe neonatal morbidity.Discussion: The CEPRA trial will identify whether the CPR is a good indicator for delivery in women with perceived reduced fetal movements.Trial Registration: Dutch trial registry (NTR), trial NL7557 .

AMNIOCENTESIS , *DIAGNOSIS of fetal diseases , *OBSTETRICS surgery , *OBSTETRICS , *PREMATURE labor - Abstract
Background: To assess the indications and complications of late amniocentesis and the advanced genetic test results in a tertiary university fetal medical medicine unit.Methods: In this retrospective study, women that underwent amniocentesis at 24+ 0 to 39+ 4 weeks, between January 2014 and December 2019, were recruited. Indications, complications, genetic test results, and pregnancy outcomes were reported for each pregnancy and compared with those who underwent the traditional amniocentesis at 16+ 0 to 23+ 6 weeks (control group). Information was retrieved from patient medical records, checked by research staff, and analyzed.Results: Of the 1287 women (1321 fetuses) included in the late amniocentesis group, late detected sonographic abnormalities (85.5%) were the most common indication. The overall incidence of preterm birth and intrauterine demise after amniocentesis were 2.5 and 1.3%, respectively. Sixty-nine fetuses with aneuploidy (5.3%) and seventy-two fetuses with pathogenic copy number variations (5.5%) were identified by chromosomal microarray analysis. The maximal diagnostic yield (70%) was in the subgroup of fetuses with the abnormal diagnostic test results, followed by abnormal NIPT results (35.7%) and multiple abnormalities (23.8%). And 35.4% of the pregnancies were finally terminated.Conclusions: Due to the high detection rates of advanced genetic technologies and the safety of the invasive procedure (3.9% vs 4.0%), it is reasonable to recommend late amniocentesis as an effective and reliable method to detect late-onset fetal abnormalities. However, chromosomal microarray and whole-exome sequencing may result in uncertain results like variants of uncertain significance. Comprehensive genetic counseling is necessary.

Objective This study was aimed to assess the utility of diagnostic tests of maternal and fetal infection in the evaluation of stillbirth. Study Design A single-center retrospective study from January 2011 to December 2016 of all women presenting to the hospital with intrauterine fetal death at or after 20 weeks of gestation. Standard evaluation included review of medical records, clinical and laboratory inflammatory workup, maternal serologies, fetal autopsy, placental pathology, and fetal and placental cultures. A suspected infectious etiology was defined as meeting at least two diagnostic criteria, and only after exclusion of any other identifiable stillbirth cause. Results During the 7-year study period, 228 cases of stillbirth were diagnosed at our center. An infectious etiology was the suspected cause of stillbirth in 35 cases (15.3%). The mean gestational age of infection-related stillbirth was 28 1/7 (range: 22–37) weeks, while for a noninfectious etiology, it was 34 0/7 (range: 25–38) weeks (p = 0.005). Placental histological findings diagnostic of overt chorioamnionitis and funisitis were observed in 31 (88.5%) cases. In 16 (45.7%) cases the placental and fetal cultures were positive for the same pathogen. Serology of acute infection was positive in three (8.5%) of the cases. Conclusion Maternal and fetal infectious workup is valuable in the investigation of stillbirth, particularly before 30 weeks of gestation and should be considered a part of standard evaluation.

Clinical chorioamnionitis at term is considered the most common infection-related diagnosis in labor and delivery units worldwide. The syndrome affects 5–12% of all term pregnancies and is a leading cause of maternal morbidity and mortality as well as neonatal death and sepsis. The objectives of this study were to determine the (1) amniotic fluid microbiology using cultivation and molecular microbiologic techniques; (2) diagnostic accuracy of the clinical criteria used to identify patients with intra-amniotic infection; (3) relationship between acute inflammatory lesions of the placenta (maternal and fetal inflammatory responses) and amniotic fluid microbiology and inflammatory markers; and (4) frequency of neonatal bacteremia. This retrospective cross-sectional study included 43 women with the diagnosis of clinical chorioamnionitis at term. The presence of microorganisms in the amniotic cavity was determined through the analysis of amniotic fluid samples by cultivation for aerobes, anaerobes, and genital mycoplasmas. A broad-range polymerase chain reaction coupled with electrospray ionization mass spectrometry was also used to detect bacteria, select viruses, and fungi. Intra-amniotic inflammation was defined as an elevated amniotic fluid interleukin-6 (IL-6) concentration ≥2.6 ng/mL. (1) Intra-amniotic infection (defined as the combination of microorganisms detected in amniotic fluid and an elevated IL-6 concentration) was present in 63% (27/43) of cases; (2) the most common microorganisms found in the amniotic fluid samples were Ureaplasma species, followed by Gardnerella vaginalis; (3) sterile intra-amniotic inflammation (elevated IL-6 in amniotic fluid but without detectable microorganisms) was present in 5% (2/43) of cases; (4) 26% of patients with the diagnosis of clinical chorioamnionitis had no evidence of intra-amniotic infection or intra-amniotic inflammation; (5) intra-amniotic infection was more common when the membranes were ruptured than when they were intact (78% [21/27] vs. 38% [6/16]; p=0.01); (6) the traditional criteria for the diagnosis of clinical chorioamnionitis had poor diagnostic performance in identifying proven intra-amniotic infection (overall accuracy, 40–58%); (7) neonatal bacteremia was diagnosed in 4.9% (2/41) of cases; and (8) a fetal inflammatory response defined as the presence of severe acute funisitis was observed in 33% (9/27) of cases. Clinical chorioamnionitis at term, a syndrome that can result from intra-amniotic infection, was diagnosed in approximately 63% of cases and sterile intra-amniotic inflammation in 5% of cases. However, a substantial number of patients had no evidence of intra-amniotic infection or intra-amniotic inflammation. Evidence of the fetal inflammatory response syndrome was frequently present, but microorganisms were detected in only 4.9% of cases based on cultures of aerobic and anaerobic bacteria in neonatal blood.

Purpose of review: The criteria for the diagnosis of intra-amniotic infection (IAI) were derived from a study of women at term in labor but is currently used as the main diagnostic tool for clinical chorioamnionitis. Regarding the inconsistent usage of the term, the diagnostic utility of clinical chorioamnionitis needs to be revisited. In this review, we addressed the critical issues on why the diagnostic criteria of suspected clinical chorioamnionitis should be changed.Recent findings: Overall, the accuracy of clinical chorioamnionitis to detect intra-amniotic infection (IAI) is not high, around 50%. The accuracy of each diagnostic criteria to diagnose IAI is, for example, 51.1% with maternal tachycardia, 57.8% with fetal tachycardia, and 55.6% with maternal leukocytosis. However, it needs to be reminded that these diagnostic performances had been obtained from term pregnancies but not from preterm pregnancies. Since there is a difference between clinical chorioamnionitis and histologic chorioamnionitis or even IAI, the diagnostic criteria of clinical chorioamnionitis would be ideal if it could directly predict the development of neonatal infectious outcomes. In fact, multiple definitions of clinical chorioamnionitis either in more lenient or stringent manner are currently used, which is responsible for inconsistent association of clinical chorioamnionitis with long-term neonatal outcomes. Whereas the diagnosis of clinical chorioamnionitis in preterm is followed by expeditious delivery, the diagnosis of clinical chorioamnionitis at term pregnancy is usually conducted in laboring women and requires additional neonatal evaluation for sepsis, which suggests different implications of clinical chorioamnionitis in preterm and term pregnancy.Summary: Current diagnostic criteria of clinical chorioamnionitis should be revised, specifically in terms of sensitivity in preterm pregnancy and specificity in term pregnancy.

Congenital abnormalities are a common cause of perinatal mortality and may have implications for life expectancy and quality of life in the future. Ultrasound screening in pregnancy can detect major congenital abnormalities in 2–3% of fetuses. Screening provides the opportunity for a diagnosis to be made prior to birth, for further investigations and monitoring to be offered, and for prognosis to be discussed. Conditions may be identified that would benefit from prenatal treatment, delivery at a different centre, or highlight that the baby may die shortly after birth. In countries where the law permits termination of pregnancy it can give the opportunity to choose not to continue the pregnancy. This article describes the Fetal Anomaly Screening Programme (FASP) in the UK and describes a systematic approach for scanning for fetal anomalies in the first and second trimester.

Objective: Pyroptosis is an inflammatory form of programmed cell death that is mediated by the activation of the inflammasome and depends on the pore-forming function of gasdermin D. Therefore, the detection of gasdermin D represents in vivo evidence of pyroptosis. We recently showed that there is intra-amniotic inflammasome activation in spontaneous labor at term; however, evidence of pyroptosis is lacking. The objectives of this study were to investigate (1) whether gasdermin D is detectable in the amniotic fluid of women who delivered at term; (2) whether amniotic fluid gasdermin D concentrations are associated with the process of spontaneous labor at term; and (3) whether gasdermin D is expressed in the chorioamniotic membranes from these patients.Methods: This retrospective cross-sectional study included amniotic fluid samples from 41 women who underwent spontaneous labor at term (n = 17) or delivered at term without labor (n = 24). As a readout of pyroptosis, gasdermin D was determined in amniotic fluid samples using a specific and sensitive ELISA kit. The 90th percentile of amniotic fluid gasdermin D concentrations was calculated among women without spontaneous labor at term (reference group). The association between high amniotic fluid gasdermin D concentrations (≥90th percentile in the reference group) and spontaneous labor at term was tested using the Fisher's exact test. A p value <.05 was considered significant. Multiplex immunofluorescence staining and phenoptics (multispectral imaging) were performed to determine gasdermin D expression in the chorioamniotic membranes and to colocalize this protein with the inflammasome-related molecules caspase-1 and interleukin-1β.Results: (1) Gasdermin D is present in the amniotic fluid of women who delivered at term; (2) the 90th percentile of amniotic fluid gasdermin D concentrations in women who delivered at term without spontaneous labor was 3.4 ng/mL; (3) the proportion of women with amniotic fluid gasdermin D concentrations above the threshold was higher in those who underwent term labor than in those who delivered at term without labor; (4) amniotic fluid concentrations of gasdermin D > 3.4 ng/mL were significantly associated with the presence of spontaneous labor in women who delivered at term (odds ratio 6.0, p-value .048); and (5) the protein expression of gasdermin D is increased in the chorioamniotic membranes of women who underwent spontaneous labor at term and is colocalized with caspase-1 and IL-1β.Conclusions: Gasdermin D is increased in the amniotic fluid and chorioamniotic membranes of women who underwent spontaneous labor at term compared to those without labor. These data provide evidence implicating pyroptosis in the mechanisms that lead to the sterile inflammatory process of term parturition. [ABSTRACT FROM AUTHOR]

Introduction: The aim of the present study was to identify possible associations of fetal heart rate (FHR) patterns during the last 2 hours of labor with fetal asphyxia expressed by umbilical artery acidemia at birth and with neonatal complications in a large obstetric cohort.Material and Methods: Cardiotocographic recordings from 4988 singleton term childbirths over 1 year were evaluated retrospectively and blinded to the pregnancy and neonatal outcomes in a university teaching hospital in Helsinki, Finland. Umbilical artery pH, base excess and pO2 , low Apgar scores at 5 minutes, need for intubation and resuscitation, early neonatal hypoglycemia, and neonatal encephalopathy were used as outcome variables. According to the severity of the neonatal complications at birth, the cohort was divided into three groups: no complications (Group 1), moderate complications (Group 2) and severe complications (Group 3).Results: Of the 4988 deliveries, the ZigZag pattern (FHR baseline amplitude changes of >25 bpm with a duration of 2-30 minutes) occurred in 11.7%, late decelerations in 41.0%, bradycardia episodes in 52.9%, reduced variability in 36.7%, tachycardia episodes in 13.9% and uterine tachysystole in 4.6%. No case of saltatory pattern (baseline amplitude changes of >25 bpm with a duration of >30 minutes) was observed. The presence of the ZigZag pattern or late decelerations, or both, was associated with cord blood acidemia (odds ratio [OR] 3.3, 95% confidence interval [CI] 2.3-4.7) and severe neonatal complications (Group 3) (OR 3.3, 95% CI 2.4-4.9). In contrast, no significant associations existed between the other FHR patterns and severe neonatal complications. ZigZag pattern preceded late decelerations in 88.7% of the cases. A normal FHR preceded the ZigZag pattern in 90.4% of the cases, whereas after ZigZag episodes, a normal FHR pattern was observed in only 0.9%.Conclusions: ZigZag pattern and late decelerations during the last 2 hours of labor are significantly associated with cord blood acidemia at birth and neonatal complications. The ZigZag pattern precedes late decelerations, and the fact that normal FHR pattern precedes the ZigZag pattern in the majority of the cases suggests that the ZigZag pattern is an early sign of fetal hypoxia, which emphasizes its clinical importance.
