Susceptible windows of exposure to fine particulate matter and fetal growth trajectories in the Spanish INMA (INfancia y Medio Ambiente) birth cohort. ENVIRONMENTAL RESEARCH 2023; 216:114628. [PMID: 36279916 PMCID: PMC9847009 DOI: 10.1016/j.envres.2022.114628] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/26/2022] [Revised: 10/13/2022] [Accepted: 10/18/2022] [Indexed: 06/16/2023]
Abstract
While prior studies report associations between fine particulate matter (PM2.5) exposure and fetal growth, few have explored temporally refined susceptible windows of exposure. We included 2328 women from the Spanish INMA Project from 2003 to 2008. Longitudinal growth curves were constructed for each fetus using ultrasounds from 12, 20, and 34 gestational weeks. Z-scores representing growth trajectories of biparietal diameter, femur length, abdominal circumference (AC), and estimated fetal weight (EFW) during early (0-12 weeks), mid- (12-20 weeks), and late (20-34 weeks) pregnancy were calculated. A spatio-temporal random forest model with back-extrapolation provided weekly PM2.5 exposure estimates for each woman during her pregnancy. Distributed lag non-linear models were implemented within the Bayesian hierarchical framework to identify susceptible windows of exposure for each outcome and cumulative effects [βcum, 95% credible interval (CrI)] were aggregated across adjacent weeks. For comparison, general linear models evaluated associations between PM2.5 averaged across multi-week periods (i.e., weeks 1-11, 12-19, and 20-33) and fetal growth, mutually adjusted for exposure during each period. Results are presented as %change in z-scores per 5 μg/m3 in PM2.5, adjusted for covariates. Weeks 1-6 [βcum = -0.77%, 95%CrI (-1.07%, -0.47%)] were identified as a susceptible window of exposure for reduced late pregnancy EFW while weeks 29-33 were positively associated with this outcome [βcum = 0.42%, 95%CrI (0.20%, 0.64%)]. A similar pattern was observed for AC in late pregnancy. In linear regression models, PM2.5 exposure averaged across weeks 1-11 was associated with reduced late pregnancy EFW and AC; but, positive associations between PM2.5 and EFW or AC trajectories in late pregnancy were not observed. PM2.5 exposures during specific weeks may affect fetal growth differentially across pregnancy and such associations may be missed by averaging exposure across multi-week periods, highlighting the importance of temporally refined exposure estimates when studying the associations of air pollution with fetal growth.

Abstract
OBJECTIVE To evaluate whether the risk of fetal malpresentation following mechanical labor induction could be accurately predicted. METHODS A retrospective study, including all individuals who underwent labor induction at a single tertiary medical center between March 2011 and May 2021. Cohorts of pharmacological (n = 16 480) and mechanical labor induction (n = 6864) were compared, determining malpresentation rate following induction. Individuals with and without fetal malpresentation following balloon placement were compared. RESULTS Malpresentation following balloon placement occurred in 62 patients (0.9%). Those patients with malpresentation following balloon placement were older, had higher body mass index during labor, higher parity, polyhydramnios, higher fetal station at the start of labor induction, and delivered at an earlier gestational age compared with control patients. The combined presence of at least three of these risk factors was associated with a malpresentation rate of 8% (7/88) and yielded a positive likelihood ratio of 9.48 (95% confidence interval [CI] 4.57-19.7). A prediction model using these variables was not sufficiently accurate to predict the risk of malpresentation following balloon labor induction; a calculated area under the generated receiver operating characteristic curve was 0.78 (95% CI 0.72-0.84). CONCLUSION Several risk factors were identified for malpresentation following mechanical labor induction, although these were of low predictive value.

Abstract
OBJECTIVE To compare the rates of adverse outcomes with postpartum hemorrhage (PPH) before and after implementation of drills or simulation exercises. STUDY ELIGIBILITY CRITERIA We included all English studies that reported on rates of PPH and associated complications during the pre- and post-implementation of interventional exercises. STUDY APPRASIAL AND SYNTHESIS METHODS Two investigators independently reviewed the abstracts, and full articles for eligibility of all studies. Inconsistencies related to study evaluation or data extraction were resolved by a third author. The co-primary outcomes were the rate of PPH and of any transfusion; the secondary outcomes included admission to the intensive care unit (ICU), transfusion ≥ 4 units of packed red blood cells, hysterectomy, or maternal death. Study effects were combined by Bayesian meta-analysis and reported as risk ratios (RR) and 95% credible intervals (Cr). RESULTS We reviewed 142 full length articles. Of these, 18 publications, with 355,060 deliveries-150,562 (42%) deliveries during the pre-intervention and 204,498 (57.6%) deliveries in the post-interventional period-were included in the meta-analysis. Using the Newcastle-Ottawa Scale, only three studies were considered good quality, and none of them were done in the US. The rate of PPH prior to intervention was 5.06% and 5.46% afterwards (RR 1.09, 95% CI 0.87-1.36; probability of reduction in the diagnosis being 21%). The likelihood of transfusion decreased from 1.68% in the pre-intervention to 1.27% in the post-intervention period (RR 0.80, 95% Cr 0.57-1.09). The overall probability of reduction in transfusion was 93%, albeit it varied among studies done in non-US countries (96%) versus in the US (23%). Transfusion of 4 units or more of blood occurred in 0.44% of deliveries before intervention and 0.37% afterwards (RR of 0.85, 95% CI 0.50-1.52), with the overall probability of reduction being 72% (76% probability of reduction in studies from non-US countries and 49% reduction with reports from the US). Surgical interventions to manage PPH, which was not reported in any US studies, occurred in 0.14% before intervention and 0.28% afterwards (RR 1.29; 95% CI 0.56-3.06; probability of reduction 27%). Admission to the ICU occurred in 0.10% before intervention and 0.08% subsequently (RR 0.92, 95% CI 0.58-1.43), with the overall probability of reduction being 65% (81% in studies from non-US countries and 27% from the study done in the US). Maternal death occurred in 0.17% in the pre-intervention period and 0.09% during the post-intervention (RR 0.62, 95% CI 0.33-1.05; probability of reduction 93% in studies from non-US countries and 82% in one study from the US). CONCLUSIONS Interventions to reduce the sequelae of PPH are associated with decrease in adverse outcomes. The conclusion, however, ought not to be accepted reflexively for the US population. All of the studies on the topic done in the US are of poor quality and the associated probability of reduction in sequelae are consistently lower than those done in other countries. SYNOPSIS Since the putative benefits of PPH drills or simulation exercises are based on poor quality pre- and post-intervention trials, policies recommending them ought to be revisited.

Abstract
OBJECTIVE To describe timing, antecedent events, and outcomes in pregnancy-related stroke (PAS). METHODS Retrospective single-center cohort of all PAS within 42 days of delivery from September 2010 to May 2021. Data were abstracted from medical records. RESULTS Among 51 500 births, we identified 91 cases of PAS, with a stroke rate of 177 per 100 000 births. Of all PAS, 62% (n = 56) were hemorrhagic, 56% (n = 51) occurred postpartum, 49% (n = 45) occurred in patients with hypertensive disorders of pregnancy (HDP), and 36% (n = 33) had surgical interventions. There were nine deaths, with a case fatality rate of 9.9%. Of the survivors (n = 82), 37 (45.1%) had residual deficits. Patients with HDP were more likely to have a postpartum stroke than those without HDP (crude relative risk 1.72, 95% confidence interval 1.16-2.55). Among patients with HDP, 89% had at least one severe range blood pressure (BP), with a peak systolic BP of 187.8 ± 27.9 mm Hg and a peak diastolic BP of 109.4 ± 18.4 mm Hg. There was no difference in presenting symptoms (P = 0.120), residual deficits (P = 0.609), or mortality (P = 0.739) between those with or without HDP. CONCLUSIONS At a referral hospital, PAS was uncommon but was associated with a high mortality rate. An improved understanding of the modifiable risk factors is warranted to avert the sequelae of PAS.

Abstract
OBJECTIVE This study aimed to evaluate the outcomes among individuals who were eligible and approached for participation in a randomized controlled trial during pregnancy, comparing those who enrolled with those who declined participation. DATA SOURCES MEDLINE, Scopus, CINAHL, the Cochrane Library, and Ovid were searched from study inception to May 2022. STUDY ELIGIBILITY CRITERIA This study included all obstetrical randomized controlled trials that reported clinical outcomes for both participants and nonparticipants. METHODS The primary outcome captured the presence of morbidity. It was a composite of the primary outcome of each study comparing the participant arm with the nonparticipant arm. If a primary outcome was not clearly defined, a surrogate was developed on the basis of the core outcomes for the clinical condition studied. The risk of bias was assessed with the Newcastle-Ottawa Scale. Subgroup analyses for relevant obstetrical and neonatal outcomes were performed. The summary comparisons were reported as odds ratios with 95% confidence intervals computed using random-effects meta-analysis with heterogeneity evaluated using the I2 statistic. A funnel plot was used to examine publication bias, and there was no asymmetry. RESULTS After reviewing more than 1100 abstracts, 17 obstetrical randomized controlled trials (103,610, with 26,293 participants and 77,317 nonparticipants) met our inclusion criteria and were analyzed. Of note, 9 studies were not rated as high quality, primarily for failing to control for confounding factors. Trial interventions were categorized as antepartum (n=11), intrapartum (n=5), or postpartum (n=1). Overall, participants in obstetrical randomized controlled trials had no difference in outcomes compared with nonparticipants (n=17: odds ratio, 0.88; 95% confidence interval, 0.52-1.49; I2=90%). Moreover, there was no difference seen when only randomized controlled trials that reported a primary outcome were included (n=12: odds ratio, 0.76; 95% confidence interval, 0.38-0.1.49; I2=93%). In addition, there was no difference noted in the subgroup where the randomized controlled trial intervention was not available to nonparticipants (n=7: odds ratio, 0.91; 95% confidence interval, 0.45-1.85; I2=68%). CONCLUSION Pregnant individuals who agreed to participate in randomized controlled trials had no difference in outcomes compared with those who decline participation. Pregnant individuals should be provided with this reassuring information when offered to participate in a randomized controlled trial. Moreover, this information may improve patient recruitment into randomized controlled trials.

Abstract
OBJECTIVE Society for Maternal-fetal medicine Consult Series (#46) states "antenatal fetal surveillance is not required for mild idiopathic" polyhydramnios defined as amniotic fluid index (AFI) of 24 cm or a deepest vertical pocket (DVP) between 8 and 11 cm. The objective of this study was to determine the cutoff for DVP which correlates with AFI ≥ 30 cm. METHODS This retrospective study of singleton third trimester ultrasounds included a study group randomly divided into test and validation. In the test group, DVP cutoffs correlating with AFI ≥ 30 cm which was used to define moderate-severe polyhydramnios were calculated in two ways, rounded to the nearest whole number: 1) a receiver operating curve and Youden's J statistic (DVP-Youden) and 2) calculation of the DVP percentile that corresponded with AFI of 30 cm (DVP-Percentile). Using the validation group, diagnostic characteristics were DVP-Youden and DVP-Percentile for diagnosis of AFI ≥ 30 cm and were compared against SMFM cutoffs (DVP-SMFM). RESULTS Seventy one thousand eight hundred and ninety three ultrasound exams in the 3rd trimester had assessment of AFI and DVP. Moderate-severe polyhydramnios occurred in 286 (1.2%) in test group and 571 (1.2%) in validation group. AFI of 30 cm corresponded to the 98.9th percentile, which in turn correlated to a DVP of 10 cm (DVP-Percentile). The calculated cutoff for moderate-severe polyhydramnios was 8 cm for DVP-Youden. CONCLUSION Using 8.0 cm rather than 12.0 cm increased the detection of moderate-severe polyhydramnios to 100% with a false positive rate under 5%. For those utilizing DVP for amniotic fluid evaluation, identification of a DVP ≥ 8.0 cm should prompt further evaluation with complete AFI.

Abstract
Most of our knowledge pertaining to this obstetric emergency has emanated from case reports and retrospective studies that have subsequently resulted in empirical management protocols. This article has identified the existence of large gaps in our clinical knowledge base regarding the prevention and resolution of shoulder dystocia, as well as its long-term sequelae. We have attempted to challenge current recommendations regarding whether prophylactic cesarean delivery should be performed based on estimated fetal weight alone or a prior history of shoulder dystocia, shoulder dystocia management techniques, what defines "excessive" traction, and the role of simulation training for all clinicians.

Abstract
BACKGROUND Small-for-gestational-age neonates (birthweight of <10th percentile for gestational age) are significantly more likely to have multiple adverse outcomes than appropriate-for-gestational-age neonates (birthweight of 10th-90th percentile). Most small-for-gestational-age neonates are undetected during pregnancy (ie, not diagnosed as fetal growth restriction), but the sequela of being undetected remains uncertain. OBJECTIVE The primary objective of this study was to compare the composite neonatal adverse outcomes among singleton pregnancies that were at least 37 weeks and delivered small-for-gestational-age neonates, which were diagnosed as either fetal growth restriction during pregnancy (detected small for gestational age) or not (undetected small for gestational age). STUDY DESIGN This was a secondary analysis of a retrospective cohort, the Consortium for Safe Labor. Singleton births at 37.0 to 41.6 weeks of gestation without congenital anomalies born small for gestational age were included in the analysis. The primary outcome was the rate of composite neonatal adverse outcome, defined as any of the following: Apgar score of <5 at 5 minutes, cardiopulmonary resuscitation at birth, respiratory distress syndrome, continuous positive airway pressure, mechanical ventilation, neonatal seizures, hypoxic-ischemic encephalopathy or diagnosis of asphyxia, intraventricular hemorrhage, necrotizing enterocolitis, neonatal sepsis, or fetal or neonatal death. The secondary outcome was the rate of composite maternal adverse outcome, which included any of the following: postpartum hemorrhage, peripartum infection, thromboembolism, hysterectomy, uterine rupture, eclampsia, intensive care unit admission, or maternal death. Small for gestational age with a prenatal diagnosis of fetal growth restriction (detected small for gestational age) was compared with small for gestational age without a prenatal diagnosis of fetal growth restriction (undetected small for gestational age). Multivariate logistic regression models were used to compare groups. A P value of <.05 was considered statistically significant. Gestational age-specific risks of composite neonatal adverse outcome and perinatal death were computed for each week of gestation among ongoing pregnancies. RESULTS Of the 228,438 deliveries in the Consortium for Safe Labor, 18,607 (8.1%) met the inclusion criteria. Among these deliveries, 17,689 (95.0%) were undetected small for gestational age, and 918 (5.0%) were detected small for gestational age. The overall rate of composite neonatal adverse outcome was 3.0%. Moreover, the rate of composite neonatal adverse outcome was similar between undetected small for gestational age and detected small for gestational age (3.0% vs 3.9%, respectively; adjusted odds ratio, 1.33; 95% confidence interval, 0.88-2.00). Some components of the composite-respiratory distress syndrome, mechanical ventilation, and necrotizing enterocolitis-were significantly higher among undetected small for gestational age than among detected small for gestational age. The overall rate of composite maternal adverse outcome was 6.2%. The rate of composite maternal adverse outcome between undetected small for gestational age and detected small for gestational age (6.2% vs 5.1%, respectively; adjusted odds ratio, 0.84; 95% confidence interval, 0.60-1.18) was similar. In gestational age-specific comparisons of composite neonatal adverse outcome, no difference was found between the undetected small-for-gestational-age group and the detected small-for-gestational-age group except for in pregnancies >41 weeks. In pregnancies at 41.0 to 41.6 weeks, the rate of composite neonatal adverse outcome was significantly greater in detected small for gestational age than in undetected small for gestational age (10.0% vs 2.5%, respectively; P=.035). CONCLUSION Antenatal detection of small for gestational age was not associated with improved composite neonatal adverse outcomes, although some components of morbidity improved with detection. Maternal outcomes did not differ between detected small for gestational age and undetected small for gestational age.

Abstract
OBJECTIVE To evaluate the association between the use of low-dose aspirin for preeclampsia prophylaxis and risks of gestational diabetes (primary outcome), neonatal hypoglycemia, macrosomia, large for gestational age, birth trauma, and shoulder dystocia (secondary outcomes). DATA SOURCES We searched Ovid MEDLINE, Embase, CINAHL, and Cochrane/CENTRAL for studies published between January 1, 1989, and April 24, 2021. STUDY SELECTION Randomized controlled trials (RCTs) or cohort studies of any size conducted in any setting were included. DATA EXTRACTION AND SYNTHESIS We assessed risk of bias using the Cochrane Risk of Bias tool 2.0 (for RCTs) and the Newcastle-Ottawa Scale (for cohort studies). We meta-analyzed relative risks (RRs) using random-effects models. CONCLUSIONS Our search retrieved 4441 records, of which 9 studies (6 RCTs with 1932 patients and 3 cohort studies with 313 837 patients) met inclusion criteria. We rated only 4 of the 6 RCTs and 1 of the 3 cohort studies at low risk of bias. Low-dose aspirin in pregnancy for preeclampsia prophylaxis was not associated with a greater risk of gestational diabetes (RR 1.18; 95% confidence interval 0.80-1.74). No studies reported data for the secondary outcomes. In summary, the use of low-dose aspirin does not appear associated with risk of gestational diabetes. The poor quality and small number of studies limit the interpretation of these results.

Abstract
OBJECTIVE To compare stress, anxiety and depression levels among 3 groups of pregnant women: 1) low-risk outpatient (LRO), 2) high-risk outpatient (HRO), and 3) inpatient (IP). METHODS This was a cross-sectional study using validated instruments. Inclusion criteria were pregnancies 23-37 weeks and maternal age > 18 years. The primary outcome was mean/median scores of Perceived Stress Scale (PSS), State Trait Anxiety Inventory (STAI), and Edinburgh Depression Scale (EDS). Secondary outcome was rate of abnormal scores. RESULTS Among 190 women approached, 180 (95%) participated, with 60 (33%) in each group. Mean PSS scores (range 0-40) significantly increased from LRO (12.0, standard deviation [SD] 7.8) to HRO (14.7, SD 7.9) to IP (15.6, SD 8.2); p = .04. Mean STAI scores (range 20-80) also significantly increased from LRO (32.0, SD 11.1) to HRO (35.8, SD 11.9) to IP (40.9, SD 13.1); p < .01. Abnormal anxiety (STAI ≥ 40) was present in 40% of women and significantly higher among IP compared to LRO (56% vs 25%; RR 2.24, 95% CI 1.36-3.67; aRR 2.24, 95% CI 1.34-3.74). CONCLUSION Stress and anxiety scores significantly differ in LRO, HRO, and IP women. While depression screening is common postpartum, screening for stress, anxiety and depression prenatally may be beneficial.

Abstract
INTRODUCTION To determine the impact of route of delivery on maternal outcomes among individuals who deliver preterm (before 37 weeks). MATERIALS AND METHODS This was a population-based retrospective cohort study using the U.S. vital statistics datasets on Period Linked Birth-Infant Death Data from 2014 to 2018. The study population was restricted to live births from women with non-anomalous singletons who delivered at 24-36 weeks of gestation. The main explanatory variable for this study was route of delivery, which was categorized as: (i) vaginal delivery, (ii) cesarean delivery with labor, and (iii) cesarean delivery without labor. The primary outcome was composite maternal adverse outcome, which encompassed any of the following: admission to the intensive care unit, maternal blood transfusion, uterine rupture, or unplanned hysterectomy. The results were presented as adjusted relative risk (aRR) with 95% confidence interval (CI). RESULTS Over the study period 1,440,510 live births met the inclusion criteria, and the overall composite maternal adverse outcome was 14.38 per 1,000 live births. After multivariable adjustment, compared to women who underwent a vaginal delivery, the risk of composite maternal adverse outcome was higher in women who had a cesarean delivery with labor (aRR 3.70; 95% CI 3.52-3.90) and those who had a cesarean delivery without labor (aRR 4.79; 95% CI 4.59-4.98). CONCLUSION With preterm birth, cesarean delivery without labor has higher rate of composite maternal morbidity than cesarean during labor or vaginal delivery.

Abstract
OBJECTIVE To ascertain the composite maternal and neonatal outcomes in pregnant individuals with moderate, severe, or critical coronavirus disease 2019 (COVID-19) treated with remdesivir. MATERIALS AND METHODS This is a secondary analysis of the COVID in Pregnancy Registry in Houston, Texas. Women were included if they met the criteria of moderate, severe or critical COVID-19 illness. Composite adverse maternal outcome was defined as any of the following outcomes: placental abruption, pregnancy-related hypertension, chorioamnionitis, stroke, delivery with estimated blood loss >1000 mL, diagnosis of pulmonary embolism or deep venous thromboembolism, or maternal death. Composite adverse neonatal outcome was defined as any of the following: Apgar score ≤3 at 5 min, arterial cord pH <7.0, positive SAR-CoV-2 test, intraventricular hemorrhage, periventricular leukomalacia, stillbirth, or neonatal death. Comparative analyses between participants receiving remdesivir versus those not exposed were performed. RESULTS A total of 994 patients were diagnosed with COVID-19 infection. Of these, 95 (9.6%) met criteria for moderate, severe, or critical disease. Forty-one percent of these patients (n = 39) received remdesivir. Baseline demographic characteristics were not different between groups. No patients reported an allergic reaction with the administration of remdesivir; however, 16.7% of the patients had the medication discontinued due to transaminitis. Patients receiving the drug were more likely to have a longer illness duration on admission, more likely to require oxygen support on arrival and have a longer hospital stay. CONCLUSIONS Remdesivir appears to be safe, well tolerated within our cohort with no cases of recorded adverse reaction.

Abstract
OBJECTIVE To compare the rate and severity of abnormal amniotic fluid volumes (oligohydramnios or polyhydramnios), as well as the distribution of amniotic fluid levels, in pregnancies with and without diabetes. METHODS We performed a retrospective cohort study of singleton nonanomalous pregnancies receiving an ultrasound examination (USE) in the third trimester. Pregnancies were categorized into those with and without diabetes and subcategorized by diabetes type. The primary outcomes were oligohydramnios or polyhydramnios. Polyhydramnios was also examined by severity. The association between maternal diabetes status and oligohydramnios or polyhydramnios was assessed using logistic regression. In addition, we computed gestational age-specific amniotic fluid index (AFI) and deepest vertical pocket (DVP) centiles for pregnancies with and without diabetes. RESULTS There were 60,226 USEs from 26,651 pregnancies that met inclusion criteria. There were 3992 (15.0%) pregnancies with diabetes and 22,659 (85.0%) without diabetes. Using AFI, the rate of polyhydramnios was 10.5 versus 3.8% (odds ratio [OR] 2.95; 95% confidence interval [CI] 2.62-3.32) for pregnancies with versus without diabetes, respectively; using DVP, the rate of polyhydramnios was 13.9 versus 5.4% (OR 2.84; 95% CI 2.56-3.15). Rates of oligohydramnios were also increased in pregnancies with diabetes (3.3 versus 2.6%; OR 1.26; 95% CI 1.04-1.52). The AFI and DVP were significantly higher in the cohort with diabetes between 28 and 36 weeks. CONCLUSION Within our study population, pregnancies with diabetes had increased rates of oligohydramnios and polyhydramnios as well as increased gestational age-specific amniotic fluid volumes between 28 and 36 weeks. A higher prevalence of polyhydramnios was observed using DVP as compared to AFI; nevertheless, associations were similar using either method.

Abstract
OBJECTIVE Women with placenta accreta spectrum (PAS) having an unplanned delivery may have worse outcome compared with women with a planned delivery. The primary objective of this study was to compare severe maternal morbidity among women with PAS who had a planned scheduled delivery versus an unplanned delivery. Secondary objective was to compare neonatal outcomes. STUDY DESIGN Retrospective cohort study at two tertiary centers (January 2009 to June 2019) of all women who underwent a hysterectomy with a histologic proven PAS. Primary outcome was severe maternal morbidity which defined as any of the following: transfusion of ≥4 RBC units or ureter/bowel injury. Neonatal outcome was a composite neonatal morbidity defined as any of the following: Apgar score's < 5 at 5 minutes, mechanical ventilation, or respiratory distress syndrome. Maternal demographic, clinical, and sonographic characteristics were compared between the two groups (planned vs. unplanned). Descriptive statistics were used as appropriate, and a statistical significance was established if p-value was < 0.05. RESULTS Of 109 women who underwent cesarean hysterectomy for PAS, 41 (37.6%) had an unplanned delivery. There was no significant difference in the number of previous cesarean deliveries or ultrasound findings between the two groups. Women with an unplanned delivery were more likely to bleed during pregnancy than those that had a planned delivery (p = 0.04). Women with unplanned delivery had lower gestational age at delivery (30.3 vs. 33.8 weeks, p = 0.001) had a 75% higher rate of the primary outcome (63 vs. 36%, p = 0.007) and had a higher rate of intensive care unit admissions (39 vs. 17.7%, p = 0.01) compared with women with a planned delivery. The neonatal morbidity did not differ between the two groups. CONCLUSION Since unplanned cesarean hysterectomy among women with PAS occurs in 40% and is associated with significantly higher morbidity, interventions are needed to mitigate the rate of adverse outcomes. KEY POINTS · Only 60% of women with PAS reached planned delivery at 34 weeks.. · PAS unplanned delivery is associated with high morbidity.. · Some women with PAS may need a scheduled earlier delivery..
