The aim of the study was to estimate by a survival analysis model the hazard function (HF) for neonatal metabolic acidemia (MA) throughout the 2nd stage of labor (2STG) at the time of occurrence of a terminal bradycardia ≥ 10 min requiring expedited delivery, and the cumulative incidence function (CIF) for MA according with the duration of bradycardia stratified in 10-12 min and 12 min.Singleton pregnancies experiencing terminal fetal bradycardia requiring expedited delivery in the 2STG at 38 + 0-41 + 3 weeks and delivering in the year 2019, were identified. The presence of MA (pH 7 and/or BE ≤ - 12 mmol/L) was determined based on the acid-base status in the umbilical artery cord blood. Survival analysis was used to assess the hazard function (HF) and the cumulative incidence function (CIF) for MA occurring after terminal fetal bradycardia, at the 2STG.Out of a non-consecutive population of 12,331 pregnancies, there were 52 cases that fit the inclusion criteria. Twenty-four (46.2%) of those develop MA. Abnormal quantitative pH values and the HF for MA correlated with the duration of 2STG at the time of bradycardia onset, but not with bradycardia duration. After 60 min of duration of 2STG, the HF (or instantaneous rate of failure) increased dramatically (from 1.2 to 20 about at 120 min). At paired duration of 2STG, a higher CIF was observed for the terminal bradycardia 12 min.Forty-six percent of term fetuses with terminal bradycardia had MA at birth. Despite the low sensitivity and a non-significant association with quantitative pH values, the duration of terminal bradycardia in the 2STG is associated with a higher CIF for MA.

Introduction The aim of our study is to describe the management of a maternity ward in a referral center during the COVID-19 pandemic and 2020 lockdown. Methods This is a retrospective single-center study. We analyzed the records of all women consecutively admitted to our delivery ward during lockdown and compared them with those of women admitted in the same period in 2019. Results The number of patients (1260) admitted to our department in 2020 was similar (1215) to that in 2019. Among patients admitted during lockdown, 50 presented with a Sars-CoV-2 infection (3.9%). In 2020, the number of antenatal check-ups was lower than in 2019 [7.9 (1.5) vs 8.2 (1.3), p

Introduction We investigated association between sociodemographic characteristics and COVID‐19 disease among pregnant women admitted to our unit, the largest high‐risk maternity unit in the Milan metropolitan area. Methods Between March 1, 2020 and April 30, 2020, 896 pregnant women were admitted to our Institution and tested for COVID‐19. We collected information regarding their sociodemographic characteristics. Additional information on geographical area of residence, number of family members, number of family members tested positive for COVID‐19, and clinical data was collected for women tested positive for COVID‐19. Odds ratios (ORs) and 95% confidence intervals (CIs) for the risk of developing COVID‐19 according to sociodemographic characteristics were estimated by unconditional logistic regression models. Results Among the 896 women enrolled, 50 resulted positive for COVID‐19. Pregnant women aged ≥35 years had a significantly lower risk of developing the infection (crude OR = 0.29; 95% CI:0.16–0.55). Conversely, foreign women (crude OR = 3.32; 95% CI:1.89–5.81), unemployed women (crude OR = 3.09; 95% CI: 1.77–5.40), and women with an unemployed partner (crude OR = 3.16; 95% CI: 1.48–6.79) showed a significantly higher risk of infection. Ethnicity was positively associated with the risk of developing COVID‐19 (mutually adjusted OR = 2.15; 95% CI:1.12–4.11) in the multivariate analysis. Foreign women with COVID‐19 were more likely to have a lower education level (p

It is unknown whether moderate thrombocytopenia represents a risk factor for post-partum haemorrhage (PPH). We assessed PPH risk among women with a platelet count of between 100 and 50 × 10

Background Among nonpregnant individuals, diabetes mellitus and high body mass index increase the risk of COVID-19 and its severity. Objective This study aimed to determine whether diabetes mellitus and high body mass index are risk factors for COVID-19 in pregnancy and whether gestational diabetes mellitus is associated with COVID-19 diagnosis. Study Design INTERCOVID was a multinational study conducted between March 2020 and February 2021 in 43 institutions from 18 countries, enrolling 2184 pregnant women aged ≥18 years; a total of 2071 women were included in the analyses. For each woman diagnosed with COVID-19, 2 nondiagnosed women delivering or initiating antenatal care at the same institution were also enrolled. The main exposures were preexisting diabetes mellitus, high body mass index (overweight or obesity was defined as a body mass index ≥25 kg/m2), and gestational diabetes mellitus in pregnancy. The main outcome was a confirmed diagnosis of COVID-19 based on a real-time polymerase chain reaction test, antigen test, antibody test, radiological pulmonary findings, or ≥2 predefined COVID-19 symptoms at any time during pregnancy or delivery. Relationships of exposures and COVID-19 diagnosis were assessed using generalized linear models with a Poisson distribution and log link function, with robust standard errors to account for model misspecification. Furthermore, we conducted sensitivity analyses: (1) restricted to those with a real-time polymerase chain reaction test or an antigen test in the last week of pregnancy, (2) restricted to those with a real-time polymerase chain reaction test or an antigen test during the entire pregnancy, (3) generating values for missing data using multiple imputation, and (4) analyses controlling for month of enrollment. In addition, among women who were diagnosed with COVID-19, we examined whether having gestational diabetes mellitus, diabetes mellitus, or high body mass index increased the risk of having symptomatic vs asymptomatic COVID-19. Results COVID-19 was associated with preexisting diabetes mellitus (risk ratio, 1.94; 95% confidence interval, 1.55–2.42), overweight or obesity (risk ratio, 1.20; 95% confidence interval, 1.06–1.37), and gestational diabetes mellitus (risk ratio, 1.21; 95% confidence interval, 0.99–1.46). The gestational diabetes mellitus association was specifically among women requiring insulin, whether they were of normal weight (risk ratio, 1.79; 95% confidence interval, 1.06–3.01) or overweight or obese (risk ratio, 1.77; 95% confidence interval, 1.28–2.45). A somewhat stronger association with COVID-19 diagnosis was observed among women with preexisting diabetes mellitus, whether they were of normal weight (risk ratio, 1.93; 95% confidence interval, 1.18–3.17) or overweight or obese (risk ratio, 2.32; 95% confidence interval, 1.82–2.97). When the sample was restricted to those with a real-time polymerase chain reaction test or an antigen test in the week before delivery or during the entire pregnancy, including missing variables using imputation or controlling for month of enrollment, the observed associations were comparable. Conclusion Diabetes mellitus and overweight or obesity were risk factors for COVID-19 diagnosis in pregnancy, and insulin-dependent gestational diabetes mellitus was associated with the disease. Therefore, it is essential that women with these comorbidities are vaccinated.

Background Large fetal head and neck (HN) masses can be life-threatening at birth and postnatally owing to airway obstruction. The two most frequent congenital masses that may obstruct the airway are lymphatic malformation (LM) and teratoma. The aim of this paper was to evaluate the results of our experience in the management of giant congenital HN masses and to conduct a literature review. Methods The study involved a consecutive series of 13 newborns (7 females) affected by giant HN masses. Prenatal diagnosis was achieved by means of ultrasound (US) and fetal magnetic resonance imaging (MRI). Delivery was performed by means of EXIT procedure in case of radiological evidence of airway obstruction. In the postnatal period all feasible therapeutic options (surgery, sclerotherapy, medical therapy) were discussed and adopted by a multidisciplinary team. Twelve patients underwent surgery and one received Rapamycin for one month, with consequent surgical resection owing to increasing size of the mass. Results The histopathological diagnosis was LM in 11 cases and teratoma in 2 cases. Airway obstruction was solved in 11 cases; 2 LM patients required a tracheotomy because of persistent airway obstruction. Major complications were flap necrosis (one patient) and facial nerve palsy (2 cases). Recurrence occurred in 5 patients. Conclusions The management of congenital HN masses is always challenging and necessarily requires an interdisciplinary approach. Current therapeutic options include surgery, sclerotherapy, medical therapy or a combination of them. When they are large enough to obstruct the airway, a patient-centered approach should guide timing and modality of treatment. Level of evidence IV

Introduction A potential complication of term prelabor rupture of membranes (term PROM) is chorioamnionitis with an increased burden on neonatal outcomes of chronic lung disease and cerebral palsy. The purpose of the study was to analyze the efficacy of a standing clinical protocol designed to identify women with term PROM at low risk for chorioamnionitis, who may benefit from expectant management, and those at a higher risk for chorioamnionitis, who may benefit from early induction. Material and methods This retrospective study enrolled all consecutive singleton pregnant women with term PROM. Subjects included women with at least one of the following factors: white blood cell count ≥ 15×100/μL, C-reactive protein ≥ 1.5 mg/dL, or positive vaginal swab for beta-hemolytic streptococcus. These women comprised the high risk (HR) group and underwent immediate induction of labor by the administration of intravaginal dinoprostone. Women with none of the above factors and those with a low risk for chorioamnionitis waited for up to 24 hours for spontaneous onset of labor and comprised the low-risk (LR) group. Results Of the 884 consecutive patients recruited, 65 fulfilled the criteria for HR chorioamnionitis and underwent immediate induction, while 819 were admitted for expectant management. Chorioamnionitis and Cesarean section rates were not significantly different between the HR and LR groups. However, the prevalence of maternal fever (7.7% vs. 2.9%; p = 0.04) and meconium-stained amniotic fluid was significantly higher in the HR group than in LR group (6.1% vs. 2.2%; p = 0.04). This study found an overall incidence of 4.2% for chorioamnionitis, 10.9% for Cesarean section, 0.5% for umbilical artery blood pH < 7.10, and 1.9% for admission to the neonatal intensive care unit. Furthermore, no confirmed cases of neonatal sepsis were encountered. Conclusions A clinical protocol designed to manage, by immediate induction, only those women with term PROM who presented with High Risk factors for infection/inflammation achieved similar maternal and perinatal outcomes between such women and women without any risks who received expectant management. This reduced the need for universal induction of term PROM patients, thereby reducing the incidence of maternal and fetal complications without increasing the rate of Cesarean sections.

The effect of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection on the pathophysiology of the placenta and its impact on pregnancy outcome has not yet been fully elucidated. Here, we present a comprehensive clinical, morphological, and molecular analysis of placental tissues from pregnant women with and without SARS-CoV-2 infection. SARS-CoV-2 could be detected in half of placental tissues from SARS-CoV-2-positive women. The presence of the virus was not associated with any distinctive pathological, maternal, or neonatal outcome features. SARS-CoV-2 tissue load was low in all but one patient who exhibited severe placental damage leading to neonatal neurological manifestations. The placental transcriptional response induced by high viral load of SARS-CoV-2 showed an immunopathology phenotype similar to autopsy lung tissues from patients with severe coronavirus disease 2019. This finding contrasted with the lack of inflammatory response in placental tissues from SARS-CoV-2-positive women with low viral tissue load and from SARS-CoV-2-negative women. Importantly, no evidence of vertical transmission of SARS-CoV-2 was found in any newborns, suggesting that the placenta may be an effective maternal-neonatal barrier against the virus even in the presence of severe infection. Our observations suggest that severe placental damage induced by the virus may be detrimental for the neonate independently of vertical transmission.

Recent evidence supports elective induction of labor at 39 weeks in low-risk pregnancies to improve maternal and perinatal outcomes. This evidence includes the ARRIVE trial (A Randomized Trial of Induction Versus Expectant Management). However, concerns have been raised on the external validity of the ARRIVE trial, especially with regard to the demographic and clinical characteristics of the pregnant women recruited.This study compared the outcomes in a cohort of consecutive pregnant women, who fulfilled the criteria of the ARRIVE trial and were managed expectantly in an Italian referral academic hospital, with those reported in the expectant and induction arms of the ARRIVE trial.This was a retrospective single-center study. Consecutive low-risk nulliparous women who fulfilled the ARRIVE trial criteria were evaluated for eligibility at 36-38 weeks of gestation. Those who neither developed complications nor delivered spontaneously before 39 weeks were eligible for this comparative analysis. Maternal and fetal growth and wellbeing were screened and monitored from 36 to 38 weeks of gestation.A total of 1696 patients met the established criteria at recruitment. Of these, 343 spontaneously delivered in39 weeks, 82 delivered because of maternal indication, and 37 for fetal indication. A total of 1234 pregnant women were eligible for comparison with the elective induction and the expectant management groups of the ARRIVE trial. The socioeconomic status was significantly better, maternal age was significantly higher, and body mass index was significantly lower in our cohort. Cesarean section rate in our cohort was lower than that of the expectant group of the ARRIVE trial (18.7 vs. 22.2%;In our cohort, expectant management in low-risk pregnancies with late preterm screening of feto-maternal well-being seemed to achieve better maternal and perinatal outcomes than a universal policy of induction at 39 weeks. The results of the ARRIVE trial should be carefully evaluated in different demographic and clinical settings and cannot be extended to the general population.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused a global health emergency [1, 2], with Lombardy being the epicenter of this outbreak in Italy [3].

Objective To report mode of delivery and immediate neonatal outcome in women infected with COVID‐19. Design Retrospective study. Setting Twelve hospitals in northern Italy. Participants Pregnant women with COVID‐19‐confirmed infection who delivered. Exposure COVID 19 infection in pregnancy. Methods SARS‐CoV‐2‐infected women who were admitted and delivered from 1 to 20 March 2020 were eligible. Data were collected from the clinical records using a standardised questionnaire on maternal general characteristics, any medical or obstetric co‐morbidity, course of pregnancy, clinical signs and symptoms, treatment of COVID 19 infection, mode of delivery, neonatal data and breastfeeding. Main outcome and measures Data on mode of delivery and neonatal outcome. Results In all, 42 women with COVID‐19 delivered at the participating centres; 24 (57.1%, 95% CI 41.0–72.3) delivered vaginally. An elective caesarean section was performed in 18/42 (42.9%, 95% CI 27.7–59.0) cases: in eight cases the indication was unrelated to COVID‐19 infection. Pneumonia was diagnosed in 19/42 (45.2%, 95% CI 29.8–61.3) cases: of these, 7/19 (36.8%, 95% CI 16.3–61.6) required oxygen support and 4/19 (21.1%, 95% CI 6.1–45.6) were admitted to a critical care unit. Two women with COVID‐19 breastfed without a mask because infection was diagnosed in the postpartum period: their newborns tested positive for SARS‐Cov‐2 infection. In one case, a newborn had a positive test after a vaginal operative delivery. Conclusions Although postpartum infection cannot be excluded with 100% certainty, these findings suggest that vaginal delivery is associated with a low risk of intrapartum SARS‐Cov‐2 transmission to the newborn.

Pregnancy is a prothrombotic condition characterized by a procoagulant imbalance that serves to protect women from bleeding but increases their risk for venous thromboembolism (VTE) [1]. Coronavirus disease 2019 (COVID-19) has not spared pregnant women with regards to VTE [2]. A coagulopathy that increases the risk of thrombosis has been reported in patients with severe COVID-19 infection [3]. At present, no data are available on the hemostatic status of pregnant women with COVID-19, and whether coagulation parameters are additionally influenced by COVID-19 remains unclear.

Introduction A historic cohort study was conducted to evaluate satisfaction with childbirth of a macrosomic baby according to mode of delivery. Material and methods All 559 nulliparous women who delivered a neonate weighing >4000 g between 2008 and 2012 were included. The degree of women's satisfaction with childbirth after elective cesarean, vaginal delivery or cesarean during labor was assessed using a five-level scale. Immediate neonatal and maternal outcomes were retrieved from clinical records. Long-term maternal outcomes were evaluated using four questionnaires on urinary incontinence, anal incontinence, and sexual functioning. Results Ninety-nine women underwent elective cesarean, whereas 460 attempted a vaginal delivery. In the latter group, 276 women delivered vaginally, whereas 184 underwent a cesarean during labor. Long-term outcomes were assessed in 273 women (49%; elective cesarean, n = 55; vaginal delivery, n = 135; cesarean in labor, n = 83) after a mean 3-year follow up. The proportion of long-term stress or mixed urinary incontinence was, respectively, 8%, 34%, and 12%, whereas that of anal incontinence was 7%, 19%, and 6%. Sexual functioning was similar in the three groups. No major neonatal complications were observed. When pooling the vaginal delivery and the cesarean in labor groups, the likelihood of being satisfied with childbirth was 63% in the “attempted vaginal delivery” group and 85% in the elective cesarean group (adjusted risk ratio, 0.72; 95% CI 0.61–0.84). Conclusions About one-third of women attempting a vaginal delivery of a macrosomic baby, would choose an elective cesarean if they could turn back time.

PROBLEM: The aim of this study was to determine serum levels of soluble intercellular adhesion molecule (sICAM)-1, an adhesion receptor that mediates interactions with the immune system, in physiologic and preeclamptic pregnancies. Moreover, we evaluated whether the release of sICAM-1 during pregnancy correlated to plasma fibronectin concentrations. METHOD OF STUDY: Serum was collected from 18 nonpregnant, control women, from 58 normal pregnant women during the first (n = 13), second (n = 15), and third (n = 30) trimesters, and from 25 preeclamptic patients at 27–39 weeks' gestation. All samples were assayed for sICAM-1 by a specific enzyme-linked immunoassay and for fibronectin by a nephelometric system. Serum sICAM-1 levels in preeclamptic patients were compared to those obtained from gestational-matched normal pregnant women. RESULTS: Levels of sICAM-1 were significantly elevated (P < 0.001) in each of the three trimesters of normal pregnancy (I trimester: 390.4 ± 25.7 ng/ml; II trimester: 386.3 ± 15.4 ng/ml; and III trimester: 367.3 ± 15.8 ng/ml) when compared to those of healthy nonpregnant women (263.3 ± 11.6 ng/ml). No significant difference in sICAM-1 concentrations was observed among the three trimesters. Preeclampsia was associated to a significant decrease (P < 0.01) of sICAM-1 levels (309.8 ± 11.6 ng/ml) relative to those observed in gestational-matched pregnant women (367.3 ± 15.8 ng/ml). Fibronectin and sICAM-1 levels did not correlate. CONCLUSION: The increased levels of sICAM-1 found in physiologic pregnancies and its reduction in preeclampsia may account for some of the immunologic alterations demonstrated to be associated with pregnancy.
