To assess the effectiveness of the implementation of a multilevel institutional program to reduce the rate of emergency peripartum hysterectomy (EPH) secondary to postpartum haemorrhage (PPH) in a Western world referral centre for obstetrics.Women who delivered at a tertiary care regional obstetric hub in Milan between 2012 and 2020 were retrospectively reviewed to identify cases of EPH. During the study period, several measures aimed at preventing EPH were progressively implemented: reduction of primary and repeated caesarean, update of PPH treatment protocol, implementation of massive transfusion protocol, dedicated clinical pathway for high-risk patients, regular educational sessions, daily review of critical cases with senior consultant, and periodical review of near miss cases by quality improvement committee. To investigate the possible benefits, we divided the detected cases into two groups based on the historical period (Period I, 2012-2016 vs. Period II, 2017-2020) with the main aim of comparing the rate of EPH calculated as EPH ratio per 1000 deliveries.During Period I and II there were 30,241 and 21,270 births; a total of 60 and 25 EPH were performed, respectively. EPH incidence decreased from 2.0 to 1.2‰ across the study periods (p = 0.027). Between Period I and II, we observed a reduction of institutional caesarean section rate (44.4% vs. 40.4%, p 0.0001); among cases undergoing EPH, we reported a significant reduction of massive blood transfusion (83.3% vs. 52.2%, p = 0.002), increased use (56.7% vs. 96.0%, p = 0.0004) and appropriate administration (25.0% vs. 88.0%, p 0.0001) of tranexamic acid, increased use of non-invasive Bakri Balloon tamponade (3.3% vs. 32.0%, p = 0.0002) instead of surgical techniques (38.3% vs. 16.0%, p = 0.043).A reduction of EPH incidence as a severe outcome of obstetric haemorrhage is achievable through a multilevel institutional effort. Our study may inspire a larger-scale program to improve the safety of patients experiencing PPH.

To investigate the effects of the antenatal administration of betamethasone on fetal Doppler and short term fetal heart rate variation (CTG-STV) in early growth restricted (FGR) fetuses. Post hoc analysis of data derived from the TRUFFLE study, a prospective, multicenter, randomized management trial of severe early onset FGR. Repeat Doppler and CTG-STV measurements between the last recording within 48 hours before the first dose of betamethasone (baseline value) and for 10 days after were evaluated. Multilevel analysis was performed to analyze the longitudinal course of the umbilico-cerebral ratio (UC ratio), the ductus venosus pulsatility index (DVPIV) and CTG-STV. We included 115 fetuses. A significant increase from baseline in CTG-STV was found on day + 1 (p = 0.019) but no difference thereafter. The DVPIV was not significantly different from baseline in any of the 10 days following the first dose of betamethasone (p = 0.167). Multilevel analysis revealed that, over 10 days, the time elapsed from antenatal administration of betamethasone was significantly associated with a decrease in CTG-STV (p = 0.045) and an increase in the DVPIV (p = 0.001) and UC ratio (p 0.001). Although steroid administration in early FGR has a minimal effect on increasing CTG-STV one day afterwards, the effects on Doppler parameters were extremely slight with regression coefficients of small magnitude suggesting no clinical significance, and were most likely related to the deterioration with time in FGR. Hence, arterial and venous Doppler assessment of fetal health remains informative following antenatal steroid administration to accelerate fetal lung maturation.ZIEL: Untersuchung des Effekts der antenatalen Gabe von Betamethason auf den fetalen Doppler und die Kurzzeitvariation der fetalen Herzfrequenz (CTG-STV) bei Föten mit früher Wachstumsrestriktion (FGR). Post-hoc-Analyse von Daten der TRUFFLE-Studie, einer prospektiven, multizentrischen, randomisierten Managementstudie bei schwerer, früh einsetzender FGR. Wiederholte Doppler- und CTG-STV-Messungen zwischen der letzten Aufnahme innerhalb von 48 Stunden vor der ersten Betamethason-Dosis (Ausgangswert) und über 10 Tage wurden bewertet. Eine mehrstufige Analyse erfolgte, um den longitudinalen Verlauf der umbilikal-zerebralen Ratio (UC-Ratio), des Pulsatilitätsindex des Ductus venosus (DVPIV) und der CTG-STV zu analysieren. Wir haben 115 Föten eingeschlossen. Ein signifikanter Anstieg der CTG-STV gegenüber dem Ausgangswert wurde am Tag + 1 (p = 0,019) ermittelt, danach gab es keinen Unterschied. Der DVPIV unterschied sich an keinem der 10 Tage nach erster Betamethason-Dosis signifikant vom Ausgangswert (p = 0,167). Eine mehrstufige Analyse ergab, dass die verstrichene Zeit nach der antenatalen Betamethason-Gabe über 10 Tage hinweg signifikant mit der Abnahme der CTG-STV (p = 0,045) und der Zunahme des DVPIV (p = 0,001) und der UC-Ratio (p 0,001) assoziiert war. Obwohl die Steroidverabreichung bei früher FGR eine kleine Auswirkung auf den Anstieg der CTG-STV 1 Tag darauf hatte, waren die Effekte auf die Doppler-Parameter äußerst gering mit Regressionskoeffizienten von geringer Höhe, die nicht auf klinische Signifikanz schließen lassen. Sie stehen höchstwahrscheinlich in Zusammenhang mit der Verschlechterung bei FGR im Laufe der Zeit. Daher bleibt die Beurteilung der arteriellen und venösen Doppler bezüglich des Gesundheitszustandes des Fötus aussagekräftig, nachdem diesem zur Beschleunigung der fetalen Lungenreifung antenatal Steroide verabreicht wurden.

To evaluate the diagnostic performance of third trimester ultrasound for the diagnosis of clinically significant Placenta accreta spectrum disorder (PAS) in women with a low-lying placenta (less than 20 mm from the internal cervical os) or placenta praevia (covering the os) METHODS: Pregnant women with a low-lying placenta or placenta praevia, age ≥ 18 years and gestational age at ultrasound ≥ 26+0/7 weeks of gestation were prospectively included in the study. Ultrasound suspicion of PAS was raised in the presence of at least one of these signs: (1) obliteration of the hypoechoic space between the uterus and the placenta; (2) interruption of the hyperechoic interface between the uterine serosa and the bladder wall; (3) abnormal placental lacunae. In order to assess the ability of ultrasound to detect clinically significant PAS, a composite outcome comprehensive of both active management at delivery and histopathological confirmation of PAS was considered as the reference standard. PAS was considered of clinical significance if, in addition to histological confirmation, at least one of these procedures was carried out after delivery: use of hemostatic intrauterine balloon, compressive uterine suture, peripartum hysterectomy, uterine/hypogastric artery ligation, uterine artery embolization.

Objective Stillbirth is a potentially preventable complication of pregnancy. Identifying women at high risk of stillbirth can guide decisions on the need for closer surveillance and timing of delivery in order to prevent fetal death. Prognostic models have been developed to predict the risk of stillbirth, but none has yet been validated externally. In this study, we externally validated published prediction models for stillbirth using individual participant data (IPD) meta-analysis to assess their predictive performance. Methods MEDLINE, EMBASE, DH-DATA and AMED databases were searched from inception to December 2020 to identify studies reporting stillbirth prediction models. Studies that developed or updated prediction models for stillbirth for use at any time during pregnancy were included. IPD from cohorts within the International Prediction of Pregnancy Complications (IPPIC) Network were used to validate externally the identified prediction models whose individual variables were available in the IPD. The risk of bias of the models and cohorts was assessed using the Prediction study Risk Of Bias ASsessment Tool (PROBAST). The discriminative performance of the models was evaluated using the C-statistic, and calibration was assessed using calibration plots, calibration slope and calibration-in-the-large. Performance measures were estimated separately in each cohort, as well as summarized across cohorts using random-effects meta-analysis. Clinical utility was assessed using net benefit. Results Seventeen studies reporting the development of 40 prognostic models for stillbirth were identified. None of the models had been previously validated externally, and the full model equation was reported for only one-fifth (20%, 8/40) of the models. External validation was possible for three of these models, using IPD from 19 cohorts (491 201 pregnant women) within the IPPIC Network database. Based on evaluation of the model development studies, all three models had an overall high risk of bias, according to PROBAST. In the IPD meta-analysis, the models had summary C-statistics ranging from 0.53 to 0.65 and summary calibration slopes ranging from 0.40 to 0.88, with risk predictions that were generally too extreme compared with the observed risks. The models had little to no clinical utility, as assessed by net benefit. However, there remained uncertainty in the performance of some models due to small available sample sizes. Conclusions The three validated stillbirth prediction models showed generally poor and uncertain predictive performance in new data, with limited evidence to support their clinical application. The findings suggest methodological shortcomings in their development, including overfitting. Further research is needed to further validate these and other models, identify stronger prognostic factors and develop more robust prediction models. (c) 2021 The Authors.

Neonatal lupus (NL) is an acquired disease caused by the transplacental passage of anti-SSA/Ro antibodies. The rate of congenital heart block (CHB), its most serious manifestation, ranges from 1 to 5%. The aim of this study was to retrospectively assess the prevalence of CHB in anti-SSA/Ro positive pregnant women with or without systemic autoimmune diseases from 2010 to 2020.Patients underwent monthly visit and a shared follow-up programme of weekly (16th-24th week) foetal heart rate assessment by obstetric ultrasound.322 pregnancies in 258 anti-SSA/Ro patients were included; 314 were followed from the beginning of pregnancy because of the known presence of anti-SSA/Ro autoantibodies and 1 case of CHB occurred in an anti-SSA/Ro+ asymptomatic subject (0.3%). In the same period, 8 additional patients were referred to our clinics after in utero CHB diagnosis and subsequent discovery of anti-SSA/Ro without a disease diagnosis. Globally, 9 cases of congenital CHB (2.8%) occurred: 7 complete, 1 II-III degree and 1 rst degree CHB. Anti-SSB/La positivity was associated with a higher risk of CHB (7.8% vs. 1.2%; p=0.0071). No differences in maternal or foetal outcomes were found in comparison with a large cohort of unselected pregnancies except for caesarian section. Hydroxychloroquine (HCQ) was used in 58.3% pregnancies, with a different prevalence according with maternal diagnosis.Our data suggest that anti-SSA/Ro positive patents with a de ned systemic autoimmune disease undergoing a strict follow-up since positive pregnancy test display a low risk of pregnancy complications, including but not limited to NL.

BACKGROUNDWomen’s memories of their childbirth experience tend to remain unchanged over time. This experience can be influenced by obstetric factors as well as by sociodemographic and psychological variables.OBJECTIVETo examine whether women’s perceived childbirth experience changes over time; to identify the predictors (obstetric, sociodemographic, and psychological variables) of this experience immediately after delivery and after 3 months.METHODSThis prospective longitudinal study comprised two hundred and twenty-one Italian women who completed a self-report questionnaire at two assessment points: immediately (1–3 days) after birth (Time 1) and 3 months postpartum (Time 2). At Time 1, the questionnaire included some questions on sociodemographic, psychological, and obstetric information, and the Wijma Delivery Experience Questionnaire (WDEQ(B); at Time 2 women compiled again the WDEQ(B).RESULTSRepeated measures ANOVA revealed that the childbirth experience did not change from Time 1 to Time 2. However, predictors of this experience were different between Time 1 and Time 2: at Time 1, the childbirth experience (WDEQ(B)_t1) was significantly predicted nly by type of cesarean section; at Time 2, the childbirth experience (WDEQ(B)_t2) was significantly predicted by WDEQ(B)_t1, history of psychological disorders, and type of conception.DISCUSSIONSOur findings enhance the understanding of the main predictors of a woman’s childbirth experience. Identifying areas of vulnerability is important for clinical practice, as well as for developing maternal health policies to improve women’s birth experiences, postpartum well-being, and the baby’s development.

This study reviewed the literature about the diagnosis, antepartum surveillance, and time of delivery of fetuses suspected to be small for gestational age or growth restricted. Several guidelines have been issued by major professional organizations, including the International Society of Ultrasound in Obstetrics and Gynecology and the Society for Maternal-Fetal Medicine. The differences in recommendations, in particular about Doppler velocimetry of the ductus venosus and middle cerebral artery, have created confusion among clinicians, and this review has intended to clarify and highlight the available evidence that is pertinent to clinical management. A fetus who is small for gestational age is frequently defined as one with an estimated fetal weight of

IntroductionThe study was implemented to provide guidance to decision-makers and clinicians by describing hospital care offered to women who gave birth with confirmed COVID-19 infection.Materials and methodsNational population-based prospective cohort study involving all women with confirmed COVID-19 who gave birth between February 25 and April 22, 2020 in any Italian hospital.ResultsThe incidence rate of confirmed SARS-CoV-2 infection in women who gave birth was 2.1 per 1000 maternities at a national level and 6.9/1000 in the Lombardy Region. Overall one third of the women developed a pneumonia and 49.7% assumed at least one drug. Caesarean section rate was 32.9%, no mothers nor newborns died. Six percent of the infants tested positive for SARS – CoV-2 at birth.ConclusionsClinical features and outcomes of COVID-19 in women who gave birth are similar to those described for the general population, most women developing mild to moderate illness.

OBJECTIVES: First, to compare published Doppler reference charts of the ratios of flow in the fetal middle cerebral and umbilical arteries (i.e. the cerebroplacental ratio (CPR) and umbilicocerebral ratio (UCR)). Second, to assess the association of thresholds of CPR and UCR based on these charts with short-term composite adverse perinatal outcome in a cohort of pregnancies considered to be at risk of late preterm fetal growth restriction. METHODS: Studies presenting reference charts for CPR or UCR were searched for in PubMed. Formulae for plotting the median and the 10th percentile (for CPR) or the 90th percentile (for UCR) against gestational age were extracted from the publication or calculated from the published tables. Data from a prospective European multicenter observational cohort study of singleton pregnancies at risk of fetal growth restriction at 32 + 0 to 36 + 6 weeks' gestation, in which fetal arterial Doppler measurements were collected longitudinally, were used to compare the different charts. Specifically, the association of UCR and CPR thresholds (CPR

OBJECTIVES: To explore the association between fetal umbilical and middle cerebral artery (MCA) Doppler abnormalities and outcome in late preterm pregnancies at risk of fetal growth restriction. METHODS: This was a prospective cohort study of singleton pregnancies at risk of fetal growth restriction at 32 + 0 to 36 + 6 weeks of gestation, enrolled in 33 European centers between 2017 and 2018, in which umbilical and fetal MCA Doppler velocimetry was performed. Pregnancies were considered at risk of fetal growth restriction if they had estimated fetal weight and/or abdominal circumference (AC)

Objectives. aPL, the serum biomarkers of APS, are the most common acquired causes of pregnancy morbidity (PM). This study investigates the impact of aPL positivity fulfilling classification criteria (‘criteria aPL’) and at titres lower than thresholds considered by classification criteria (‘low-titre aPL’) on PM and assesses the effectiveness of low-dose aspirin (LDASA), low molecular weight heparin (LMWH) and HCQ in reducing the probability of PM (PPM). Methods. Longitudinal data on 847 pregnancies in 155 women with persistent aPL at any titre and 226 women with autoimmune diseases and negative aPL were retrospectively collected. A generalized estimating equations model for repeated measures was applied to quantify PPM under different clinical situations. Results. EUREKA is a novel algorithm that accurately predicts the risk of aPL-associated PM by considering aPL titres and profiles. aPL significantly impact PPM when at low titres and when fulfilling classification criteria. PPM was further stratified upon the aPL tests: aCL IgG/IgM and anti-b2-glycoprotein I (b2GPI) IgM, alone or combined, do not affect the basal risks of PPM, an increase occurs in case of positive LA or anti-b2GPI IgG. LDASA significantly affects PPM exclusively in women with low-titre aPL without anti-b2GPI IgG. The LDASAþLMWH combination significantly reduces PPM in all women with low-titre aPL and women with criteria aPL, except those carrying LA and anti-b2GPI IgG. In this group, the addition of HCQ further reduces PPM, although not significantly. Conclusion. EUREKA allows a tailored therapeutic approach, impacting everyday clinical management of aPLpositive pregnant women.

OBJECTIVE: To assess the added value of Doppler parameters, maternal history, and intrapartum clinical characteristics for the prediction of emergency delivery due to non-reassuring fetal status in low-risk pregnancies. METHODS: This was a prospective cohort of low-risk pregnancies undergoing ultrasound assessment at 40 weeks' gestation within 7 days of delivery. The main outcome was emergency cesarean section due to non-reassuring fetal status. The association between Doppler parameters, intrapartum clinical characteristics, and maternal history was performed by logistic regression. The predictive performance of the constructed models was assessed by receiver operating characteristic (ROC) curve analysis and the area under the curve (AUC). RESULTS: From 403 included pregnancies, 18.6% (n = 75) underwent an emergency delivery due to non-reassuring fetal status. The mean gestational age at birth was 40.5 (SD 5) days. Middle cerebral artery pulsatility index (MCA) and cerebroplacental ratio (CPR) were lower in the emergency cesarean section group (1.16 versus 1.30; p < .001, and 1.61 versus 1.78; p = .001, respectively). There was a higher incidence of small-for-gestational-age neonates (20 versus 10.1%; p = .017), lower Apgar scores at the 5th minute (9.7 versus 9.9; p = .006), and NICU admissions (9 versus 3%; p = .016) in the emergency cesarean section group. The base model comprised nulliparity, and the finding of meconium-stained amniotic fluid during labor, achieving an AUC of 66%, while the addition of the MCA Z-score significantly improved the previous model (AUC: 73%; DeLong: p = .008). CONCLUSIONS: In low-risk pregnant woman at term, the addition of MCA Z-score to a previous model comprising maternal history and intrapartum clinical findings, significantly improves the prediction of emergency delivery due to non-reassuring fetal status.
