Background: Currently, the use of FE is decreasing and neonatal adverse outcomes following FE are underreported. We aimed to evaluate the rate of neonatal adverse outcomes in current obstetric practice at two university hospitals with a low FE volume. Methods: A multicentre retrospective study. All singleton pregnancies delivered by forceps extraction between 2011 and 2020 were analyzed. The characteristics of the deliveries with a composite neonatal adverse outcome (CNAO) were analyzed and compared with those without. Results: The study cohort included 861 neonates delivered by FE. The CNAO was recorded in 131 (15.2%). Women in the CNAO group gained less weight during pregnancy (mean 13 kg vs. 15 kg, p = .014). Factors found to be associated with CNAO were preterm delivery (gestational age < 37°7) (26 (19.8%) vs. 44 (6.0%), OR [95% CI]: 3.86 (2.28–6.52), p < .001), low birth weight (23 (17.6%) vs. 44 (6.0%), OR [95% CI] 3.32 (1.92–5.71), p < .001), and smaller head circumference (329 vs. 331 mm, OR [95% CI] 0.79 (0.67–0.93), p = .035). In a multivariate analysis, gestational age (adjusted OR [95% CI] 0.672 (0.546–0.826), p < .001) and maternal weight gain during pregnancy (adjusted OR [95% CI]: 0.950 (0.904–0.998), p = .042), were both negatively associated with CNAO. Among term deliveries, the only factor found to be independently associated with CNAO was maternal weight gain during pregnancy (adjusted OR [95% CI]: 0.951 (0.910–0.994), p = .025). Conclusions: In the setting of low volume FE, this mode of delivery is associated with a relatively low rate of neonatal morbidity. Synopsis: Performance of forceps extraction in the setting of low volume practice is associated with a relatively low rate of neonatal morbidity. [ABSTRACT FROM AUTHOR]

Objective: Subgaleal hemorrhage (SGH) is a severe neonatal morbidity that is associated with vacuum-assisted delivery (VAD). Large sonographic head circumference (sHC) was previously associated with complicated VAD. Nevertheless, the association of large sHC with SGH formation following VAD is underreported. We aim to evaluate the role of sonographic head circumference (sHC) with SGH formation following attempted VAD. Methods: A retrospective case-control study. Cases comprised singleton pregnancies for whom attempted VAD resulted in SGH with an sHC measured within 2 weeks from delivery. Controls were VAD deliveries which not resulted in SGH, with an sHC measured within 2 weeks from delivery. We matched controls in a 1:1 ratio by gestational age, parity and year of delivery. Results: Overall, 118 women were included in the SGH study group and were matched to 118 controls. Baseline maternal and fetal characteristics were similar between the groups except for higher neonatal birth weight in the SGH group (median 3422 vs. 3195 grams, p = .001). sHC did not vary between groups (median 336 mm in SGH groups vs. 333, p = .08). Rate of sHC >90th and >95th percentile did not significantly differ between the groups (13.6% vs. 8.5%, 6.8% vs. 3.4%, p = .21, p = .37, for SGH vs. controls, respectively). In multivariate regression analysis, sHC was not found to be independently associated with SGH – aOR (95% CI) 1.004 (0.97–1.03). Receiver operating characteristic curves of sHC for SGH formation underlined an area under the curve of 0.58 (95% CI) (0.51–0.65). Conclusions: sHC is not associated with SGH formation following VAD.

Objective Although repeated antenatal corticosteroids (ACS) courses are not recommended, a single rescue ACS course has been shown to decrease neonatal morbidity among preterm singletons. However, little is known regarding the effects of rescue ACS course in twin pregnancies. Methods A retrospective cohort study conducted during 2015–2017 at a tertiary-care center including all twins delivered between 24–34 weeks of gestation who received at least one course of ACS. Results Overall, 162 (70.4%) twins were exposed to a single ACS course and 68 (29.6%) to an additional rescue ACS course. Rescue ACS course was associated with lower rates of respiratory distress syndrome (7.4% vs. 19.1%, p = .03), surfactant use (7.4% vs 18.5%, p = .04) and bronchopulmonary dysplasia (0 vs 8.6%, p = .01) as compared to a single ACS course. In the rescue ACS group, compared to the single ACS group, the rates of composite respiratory adverse outcome (10.3% vs 22.2%, OR [95% CI]: 0.40 (0.17–0.95), p = .04) and any adverse neonatal outcome (13.2% vs 26.5%, OR [95% CI]: 0.42 (0.19–0.92), p = .04) were significantly lower. Hospital stay was also shorter among neonates born to mothers receiving a rescue ACS course (median 23 vs. 30 days, p = .01). No differences were noted in neonatal birthweight, head circumference and the rate of neonatal hypoglycemia. Conclusion Rescue ACS course was associated with improved respiratory and neonatal outcomes in twin gestations. Further studies are warranted to confirm our findings and better delineate the optimal regimen of rescue ACS in this setting. [ABSTRACT FROM AUTHOR]

We aimed to assess the risk of preterm birth in those with real-time dynamic cervical shortening. A retrospective matched case-control study. The study group comprised all women with dynamic cervical shortening (≥4 mm) noted from 24 to 34 weeks of gestation during 2010–2017 at a university hospital. Two control groups of women were established by matching the minimal and maximal cervical length measured, as well as age, parity, gestational age, history of spontaneous preterm birth, symptoms of preterm labor, and delivery year. Data from 339 women were analyzed, 113 with dynamic cervical shortening comprised the study group, and two groups with 113 women each, matched for the minimal and maximal cervical lengths measured comprised the control groups. Rates of spontaneous preterm birth rate at <37 weeks (32.7% vs. 15.9%; OR [95% CI]: 2.60 (1.36, 4.87), p =.004) and <35 weeks (15.9% vs. 5.3%; OR [95% CI]: 3.38 (1.29, 8.86), p =.013) were significantly higher among those with dynamic cervix than among the control group matched for the maximal cervical length, and comparable to the control group matched for the minimal cervical length. The negative predictive values of cervical length for preterm birth occurrence at various cutoff values were lower in those with dynamic cervix. The minimal cervical length measured should be used to guide patient management when dynamic cervix is noted. In the setting of dynamic cervical change, the value of cervical length as a negative predictor of preterm birth is limited. [ABSTRACT FROM AUTHOR]

Objective: Among deliveries <34 weeks, there is inconclusive evidence regarding the preferred route of delivery when there is a need to expedite delivery during the second stage of labor. As it is unreasonable that future randomized controlled trials will be conducted to settle this query, every clinical data concerning this topic, may be helpful. We aim to compare neonatal outcomes among women undergoing emergent cesarean delivery (ECD) versus vacuum-assisted delivery (VAD) during the second stage of labor among singleton gestations <34 weeks. Methods: A retrospective cohort study including all women who underwent either ECD or VAD at the second stage of labor between 30°/7 and 336/7 weeks, during 2011-2019. The primary outcome was the rate of adverse neonatal outcomes, defined as intrapartum death, mechanical ventilation, asphyxia, respiratory distress syndrome, subgaleal hemorrhage, intraventricular hemorrhage, necrotizing enterocolitis, and phototherapy. Results: Of the 153,672 live singleton deliveries during the study period, 2871 (1.9%) delivered before 34°/7. Of those 1674 (58.3%) delivered vaginally unassisted and 1137 (39.6%) delivered by a CD during the first stage of labor. A total of 60 deliveries were analyzed, with a median gestational age of 32 weeks, interquartile range (IQR) 31-33. Median birth weight at delivery was 1845 g, IQR 1574-2095. Overall 25 (42%) of women were delivered by VAD and 35 by CD (58%). Indications for expeditious delivery did not differ between the study groups. Neonates delivered by VAD had a higher median birth weight (1940 vs. 1620 g, p = .02). Second stage of labor was longer in the ECD group as compared to the VAD group (median 200 vs. 52 min, p = .01). The rate of Apgar score at 1 min <7 was higher among the CD group (10 (40%) vs. 5 (14%), OR [95% CI]: 4.0 (1.1-13.8), p = .03). Longer length of stay was evident in the CD group as compared to the VAD group (median 30 vs. 21 days, p = .001). The rate of composite neonatal adverse outcome was comparable between the study groups. Adverse outcomes were associated with lower body mass index (median 27.7 vs. 34.9, p = .04), higher rate of premature preterm rupture of membranes (40 (91%) vs. 5 (31%), OR [95% CI]: 22.0 (5.0-91.1), p < .001) and labor dystocia as the indication for expedited delivery (38 (86%) vs. 7 (44%), OR [95% CI]: 8.1 (2.1-30.1), p = .001). Conclusions: Cesarean delivery during the second stage of labor of gestations <34 weeks was associated with a higher rate of lower Apgar scores and longer length of stay. [ABSTRACT FROM AUTHOR]

Objective: Isolated oligohydramnios (IO) - oligohydramnios in the absence of maternal or gestational comorbidity is debated as an indication for induction of labor. Previous meta-analyses regarding perinatal outcomes of IO at term have yielded conflicting results. We aimed to investigate the neonatal outcomes among gestations with IO delivered at 36°/7-396/7. Methods: The study cohort included all women undergoing a trial of labor between during 2011 and 2019 of a singleton gestation with cephalic presentation between 36°/7 and 40°/7. We allocated the study groups into women with IO and those with normal amniotic fluid volume. Neonatal outcomes were compared between the groups and in relation to gestational age and induction of labor. Results: Overall, there were 529/17,709 (3.0%) IO cases. IO was associated with maternal age <25 years (OR [95% CI] 1.62 (1.20-2.20), p = .001). Induction of labor was more common with IO (OR [95% CI] 1.33 (1.05-1.69) p = .01. IO was associated with preterm delivery (OR [95% CI] 1.81 (1.36-2.40), p < .001). The rate of neonatal adverse outcome did not differ between study groups. Overall composite adverse neonatal outcome occurred among 1,399/17,709 (7.9%) deliveries. Adverse neonatal outcome was associated with induction of labor (OR [95% CI] 1.61 (1.40-1.86), p < .001) and low birth weight (OR [95% CI] 7.41 (6.27-8.75), p < .001). When Stratified by gestational age, neonatal adverse outcome did not differ between IO and no IO groups. When examining cases of induction of labor per gestational age, induction of labor at 36 weeks among IO gestations, was associated with adverse neonatal outcome as compared to no IO group (OR [95% CI] 5.7 (1.23-26.3), p = .04). Conclusions: Induction of labor in gestations complicated by IO at 36 weeks gestational age is associated with an increased risk for adverse neonatal outcome. Our study results adds to the current literature regarding outcomes of IO and time of delivery. [ABSTRACT FROM AUTHOR]

Objective: The assessment of sonographic estimated fetal weight (EFW) enables identification of fetuses in the extremes of weight, thus aiding in the planning and management of peripartum care. There are conflicting reports regarding the accuracy of EFW in diabetic mothers. We aimed to study the factors associated with the accuracy of EFW at term, specifically the role of gestational and pre-gestational diabetes in this setting.Methods: A retrospective study including all women carrying singleton term gestations who delivered within a week following a sonographic fetal weight estimation between 2011 and 2019. Accurate EFW was defined as within 10% of the actual birthweight. We allocated the study cohort into two groups: (1) Accurate EFW (2) inaccurate EFW. Both groups were compared in order to identify factors associated with the inaccuracy of EFW.Results: Overall, 41,263 deliveries were available for evaluation, including 412 (1.0%) deliveries among women with pre-gestational diabetes and 4,735 (11.5%) among women with gestational diabetes. Of them, 7,280 (17.6%) had inaccurate EFW. Inaccurate EFW was associated with nulliparity, OR 0.82 [95% CI] (0.78-0.87), oligohydramnios, OR 0.81 [95% CI] (0.71-0.93), pregestational diabetes, OR [95% CI] 0.61 (0.50-0.79), and extremity of fetal weight; <2,500 grams-OR [95% CI] 0.37 (0.33-0.41) and >4,000 grams OR [95% CI] 0.52 (0.48-0.57). On multiple regression analysis, the following factors were independently associated with inaccurate EFW: pregestational diabetes, OR [95% CI] 0.58 (0.46-0.73), p < .001, nulliparity, OR [95% CI] 0.86 (0.82-0.91), p < .001 and higher fetal weight (for each 500 grams), OR [95% CI [1.25 (1.21-1.30), p < .001. On analysis of different weight categories, pregestational diabetes was associated with inaccurate EFW only in those with birthweight >3,500 grams, OR [95% CI] 0.37 (0.24-0.56) (p < .001).Conclusion: Among pregestational diabetic women, the accuracy of sonographic EFW when assessed to be >3,500 grams is questionable. This should be taken into consideration when consulting women and planning delivery management.Synopsis: Among pregestational diabetic women, the accuracy of estimated sonographic fetal weight higher than 3,500 grams is of limited accuracy.

Cesarean delivery (CD) is a known risk factor for postpartum hemorrhage. However, the characteristics associated with post-CD transfusion are not well-established. We aimed to assess blood transfusion rates and associated factors following CD. A retrospective case-control study of women who underwent CD at a university hospital. The study group comprised all women who received blood transfusion following surgery. A control group of women who did not receive postoperative blood transfusion was assigned in a two-to-one ratio. During study period, the overall post-CD blood transfusion rate was 4.7%. The study group comprised 170 women, and the control group 340. Maternal age (aOR [95% CI]: 1.07 (1.03, 1.11), p =.001), parity (aOR [95% CI]: 1.26 (1.09, 1.47), p =.002), gestational hypertensive disorders (aOR [95% CI]: 4.07 (1.52, 10.91), p =.005), maternal comorbidities (aOR [95% CI]: 4.16 (1.88, 9.1), p <.001), lower predelivery hemoglobin level (aOR [95% CI]: 0.43 (0.34, 0.54), p <.001), and major placental abnormalities (aOR [95% CI]: 2.74 (1.04, 7.18), p =.04) were independently associated with blood transfusion requirement. Intrapartum characteristics associated with blood transfusion requirement included nonelective procedure (aOR [95% CI]: 3.21 (1.72, 5.99), p <.001), prolonged second stage of labor (aOR [95% CI]: 5.50 (2.57, 11.78), p <.001), longer duration of surgery (aOR [95% CI]: 1.03 (1.02, 1.04), p <.001), general anesthesia (aOR [95% CI]: 2.11 (1.14, 3.91), p =.02), and greater estimated operative blood loss (aOR [95% CI]: 5.72 (3.15, 10.36), p <.001). Among women who underwent CD, we identified 11 factors associated with blood transfusion following surgery. Prospective studies are warranted to assess the implementations of prophylactic interventions to reduce transfusion rates among those deemed at high risk for CD-related bleeding.

Objective: Retained placenta is a leading cause of maternal hemorrhage. A history of retained placenta is a well-recognized risk factor for recurrence; however, recurrence risk pattern has not been previously described. We aimed to evaluate the longitudinal recurrence pattern of retained placenta in multiple consecutive deliveries.Methods: This is a retrospective computerized base study conducted at Shaare Zedek Medical Center, a university-affiliated hospital, between 2005 and 2018. Medical records of parturient who had at least one coded diagnosis of either retained partial or complete placenta were retrieved. The first delivery with retained placenta diagnosis was chosen as the index delivery. In order to account for dependency between deliveries of the same individual parturient, we used a multivariate binary logistic regression with generalized estimating equation (GEE) to calculate the individual recurrence risk, adjusted odds ratios (95% confidence interval).Results: During the study period, we identified 2177 parturient diagnosed with retained placenta in the index delivery and that had at least one subsequent delivery; overall 300 (13.8%) parturient had at least one subsequent event of retained placenta: 9.3% for the subsequent delivery and 6% in later deliveries. Induction of labor and epidural analgesia either in the index or in the subsequent delivery were found to be independently associated with recurrence 1.61 (1.16-2.24), 1.45 (1.10-1.90) and 1.46 (1.11-1.93), 1.82 (1.45-2.28), respectively. Complete and not partial retained placenta in the index delivery was also found to be independently associated with recurrence 4.90 (3.90-6.32).Conclusion: For the individual parturient, an event of retained placenta is a sentinel of the subsequent deliveries and has modifiable recurrence risks.

Objective: Published series regarding interventions for facilitating external cephalic version (ECV) have concluded that parenterally administered beta-stimulant tocolytics, increased ECV success rate and reduced the number of cesarean sections. However, there were insufficient data regarding calcium channel blockers to provide good evidence regarding its efficacy. Given the paucity of literature, we aimed to compare the efficacy of nifedipine to that of ritodrine on ECV success rates.Methods: This is a retrospective case control study of prospectively collected data of patients who underwent ECV between January 2012 and December 2013 at Bikur Cholim Medical Center and Hadassah-Hebrew University Medical Center in Jerusalem, Israel. Patient undergoing ECV with tocolysis by ritodrine were compared with those using nifedipine as tocolysis. Patients were matched in a one-to-one ration by parity and placental location.Results: Overall, 148 women received ritodrine and 148 women received nifedipine before ECV procedure. Overall success rate was higher among the ritodrine group (82.4 vs. 63.5%, p < .001). Among nulliparous and among parous, success rate was higher in the ritodrine group (78.9 vs. 57.9 and 88.6 vs. 73.5%, p = .001, p = .04, respectively). Vaginal delivery rate was higher among the ritodrine group (86.5 vs. 68.9%, p < .001). Cesarean delivery rate was 31.1% for the nifedipine group versus 13.5% in the ritodrine group (p < .001). Number needed to treat to benefit (NNTb) 5.7 (95% confidence interval 3.7-12.1). Overall, 216 of 296 (72.9%) of ECV were successful. Ritodrine was associated with higher success rates as compared with nifedipine (56.5 vs. 32.5%, p < .001). In a multivariate analysis, ritodrine tocolytic therapy was independently associated higher ECV success rates as compared to nifedipine (OR 4.54, 95% CI 2.38-9.09). Higher amniotic fluid index (OR 1.16, 95% CI 1.05-1.28) and nulliparity (OR 0.16, 95% CI 0.08-0.30) were additional independent predictors of ECV outcome.Conclusion: Ritodrine significantly improve the success of ECV compared with nifedipine. Both drugs are shown to be safe. [ABSTRACT FROM AUTHOR]

Although delivery timing is physician dictated in indicated preterm births, suboptimal antenatal corticosteroids (ACS) administration occurs in most cases. We aimed to characterize the patterns of use of ACS in indicated preterm births and identify missed opportunities of optimal ACS administration. We reviewed the records of women who received ACS and were delivered due to maternal or fetal indications at 24–34 weeks of gestation during 2015–2017 at a university hospital. Optimal ACS timing was defined as delivery ≥24 h ≤7 d from the previous ACS course. Overall, 188 pregnancies were included. The median gestational age at delivery was 32 weeks. Considering only the initial ACS course, the rate of optimal timing was 32.4%. Of 105 (55.8%) women eligible (delivery >7 d since the initial ACS course), only a third (n = 38) received a rescue ACS course. Among women who did not receive rescue ACS course despite their eligibility (n = 67), the decision-to-delivery was ≥3 h in 36 (53.7%), and ≥24 h in 20 (29.9%), representing 19.1 and 10.6% of the entire cohort, respectively. The urgency of the decision to deliver (i.e. in the upcoming 24 h and later) and allowing a trial of labor, were both positively associated with decision-to-delivery interval ≥3 h and ≥24 h. The rate of delivery within any optimal window (either initial or rescue course) was 40.4%, with gestational hypertensive disorders (OR [95% CI]: 2.40 (1.23, 4.72), p =.01) and decision to deliver made at first hospitalization (OR [95% CI]: 2.27 (1.04, 4.76), p =.04) as independent positive predictors of optimal ACS timing. The rate of composite adverse neonatal outcome was significantly lower in those with optimal ACS administration as compared to those with suboptimal timing (32.9 versus 50.9%, OR [95% CI]: 0.47 (0.26, 0.87), p =.02). Suboptimal ACS administration occurred in most indicated preterm births. Underutilization of rescue ACS course and a substantial rate of missed opportunities for optimal ACS administration were identified as potentially modifiable contributors to improve ACS timing.

Objective: The efficacy of pharmacomechanical catheter-directed thrombolysis (PCDT) in preventing post thrombotic syndrome (PTS) for pregnancy related deep vein thrombosis (DVT) is unknown.Study Design: An observational cross section study of women with pregnancy related proximal (femoral/iliofemoral) DVT who underwent PCDT followed by anticoagulation (study group), and women who were treated with anticoagulation alone (control group). Women were evaluated for PTS using the Villalta scale (primary outcome) and VEINES-QOL/Sym questionnaires.Results: Eleven women with iliofemoral DVT underwent PCDT, two during their first trimester and nine postpartum; 18 women were treated with anticoagulation only. There were no significant differences in age, number of previous pregnancies, and duration of anticoagulation or thrombophilia between the groups. The time between DVT diagnosis and study inclusion was longer in the study group [median 50.5 (range 16-120) months] compared to the control group [median 27 (range 11-64) months], p = .4. None of the women in the PCDT group developed PTS, compared to six (33.3%, p = .03) in the control group, four of whom developed severe PTS. One patient in each group developed recurrent DVT, and one patient in the study group developed a calf hematoma. A reduced frequency of lower extremity symptoms was observed in the PCDT group (VEINES-Sym questionnaire), but no differences in quality of life (VEINES-QOL questionnaire) were reported.Conclusion: This study suggests that PCDT may reduce the incidence of PTS in women with pregnancy related proximal DVT.Bullet pointsDVT involving the iliofemoral veins and development of post thrombotic syndrome is frequent among pregnant or postpartum womenStudies of pharmacomechanical catheter-directed thrombolysis (PCDT) for deep vein thrombosis did not include pregnant or postpartum womenIn our observational cross section study women who underwent PCDT (mainly in the postpartum period) had reduced frequency of post-thrombotic syndrome compared to women who received anticoagulation onlyLarger studies are required to confirm the use of PCDT for prevention of PTS in this population.

Objective: To assess the maternal and neonatal outcomes following delayed diagnosis of uterine rupture (diagnosis during the early postpartum period) in comparison to women with an intrapartum diagnosis of uterine rupture. Methods: Retrospective study of electronic medical records (EMR) from 2005 to 2018 in a single large academic tertiary care. Demographic, obstetric and maternal characteristics and outcomes were retrieved and compared. Univariate, followed by multivariate analyses were applied to evaluate the association between maternal and neonatal outcomes. Only complete uterine ruptures were included. The primary outcome of this study was defined as hysterectomy rates. Secondary outcomes were maternal and neonatal morbidity parameters. Results: During the study period, 143 parturients with uterine rupture were identified from 174,189 deliveries (0.08%). Of these, 29 (20.3%) had delayed diagnosis with a median time from delivery to the operation of 4.5 hours (IQR 0.83–28 hours). Factors that were identified as independent risk factors for delayed diagnosis: an unscarred uterus (aOR 27.0, 95% CI 6.58–111.1), epidural analgesia during labor (aOR 7.9, 95% CI 2.32–27.05) and grand-multiparity (aOR 4.6, 95% CI 1.40–14.99). Maternal outcomes demonstrated that parturients with a delayed diagnosis had significantly higher rates of blood transfusions, puerperal fever, and hysterectomy (p<.001 for all). In a multivariate model, the delayed diagnosis was found to be independently associated with hysterectomy (aOR 4.90, 95% CI 1.28–19.40). There were no differences regarding to neonatal outcomes. Conclusion: Parturients with delayed diagnosis of uterine rupture have unique characteristics and poorer maternal outcomes. It is possible that awareness of this population will enable earlier diagnosis and may help improve outcomes. [ABSTRACT FROM AUTHOR]

Objective: While surgical management is the treatment of choice for abnormally invasive placenta, the role of supracervical hysterectomy in this setting is not well established. We aimed to compare supracervical versus total cesarean hysterectomy as a surgical option for abnormally invasive placenta.Methods: We carried out an 8-year retrospective case-control study. Six cases of a patient treated by total hysterectomy were matched and compared to 30 controls treated by supracervical hysterectomy. Matching of cases with controls was based on coexisting placenta previa, a number of previous cesarean sections, and age, with five controls per case. Cases and controls were comparable in placental invasion topography. We compared the operative approach in all histologically identified cases of abnormally invasive placenta.Results: Overall, 36 women with histologically proven abnormally invasive placenta were identified. Composite blood products morbidity was higher among total hysterectomy patients (p = .02). Freshly frozen plasma utilization was greater among total hysterectomy patients (p = .01). Median operative time (142 ± 48 versus 136 ± 58 minutes) and hospitalization time (8.9 ± 3.1 versus 7.3 ± 1.5 days) were comparable between those who underwent supracervical versus total hysterectomy (p > .05). No case of maternal or neonatal death was encountered.Conclusion: The favorable maternal and perinatal outcomes observed in our study, suggest that supracervical hysterectomy should be considered as the first-line approach in cases of abnormally invasive placenta managed operatively.

Objectives: To characterize the risk factors associated with neonatal thrombocytopenia among pregnant women with immune thrombocytopenic purpura (ITP).Methods: We reviewed the records of ITP patients who delivered during 2006-2016 at our medical center.Results: Of 253 pregnancies, median maternal age at diagnosis was 29 [25-33] years, 222 (87.7%) had previously-diagnosed ITP and 31 (12.3%) were diagnosed with new-onset ITP during pregnancy. Baseline characteristics were comparable between the groups except for a higher proportion of nulliparity among those with new-onset disease (p = .002). Maternal nadir platelet count was significantly lower among those with new-onset compared to previously diagnosed ITP (median 62 × 109/L versus 81 × 109/L, p = .005). Neonatal thrombocytopenia (<150 × 109/L) was encountered in 24 (9.5%) pregnancies and required treatment in 12 (50%) of them. Neonatal platelet count was directly correlated with maternal platelet count at delivery (r = 0.23, p = .01), with significantly lower maternal platelet count among those whose newborns experienced thrombocytopenia (p < .001). Neonatal thrombocytopenia followed a higher proportion of pregnancies of women with new-onset than previously diagnosed ITP (22.6 versus 7.7%, p = .02). In multivariate analysis, the presence of new-onset ITP (odds ratio [95% CI]: 4.88 (1.68, 14.16), p = .004) was the only independent predictor of the development of neonatal thrombocytopenia.Conclusion: Neonatal thrombocytopenia presented following almost one-tenth of pregnancies with ITP. New pregnancy-onset disease was the only prognostic marker for neonatal thrombocytopenia. This finding could contribute to risk stratification and individualized patient management.

Objective: Although delivery timing is physician dictated in indicated preterm births, suboptimal antenatal corticosteroids (ACS) administration occurs in most cases. We aimed to characterize the patterns of use of ACS in indicated preterm births and identify missed opportunities of optimal ACS administration.Methods: We reviewed the records of women who received ACS and were delivered due to maternal or fetal indications at 24-34 weeks of gestation during 2015-2017 at a university hospital. Optimal ACS timing was defined as delivery ≥24 h ≤7 d from the previous ACS course.Results: Overall, 188 pregnancies were included. The median gestational age at delivery was 32 weeks. Considering only the initial ACS course, the rate of optimal timing was 32.4%. Of 105 (55.8%) women eligible (delivery >7 d since the initial ACS course), only a third (n = 38) received a rescue ACS course. Among women who did not receive rescue ACS course despite their eligibility (n = 67), the decision-to-delivery was ≥3 h in 36 (53.7%), and ≥24 h in 20 (29.9%), representing 19.1 and 10.6% of the entire cohort, respectively. The urgency of the decision to deliver (i.e. in the upcoming 24 h and later) and allowing a trial of labor, were both positively associated with decision-to-delivery interval ≥3 h and ≥24 h. The rate of delivery within any optimal window (either initial or rescue course) was 40.4%, with gestational hypertensive disorders (OR [95% CI]: 2.40 (1.23, 4.72), p = .01) and decision to deliver made at first hospitalization (OR [95% CI]: 2.27 (1.04, 4.76), p = .04) as independent positive predictors of optimal ACS timing. The rate of composite adverse neonatal outcome was significantly lower in those with optimal ACS administration as compared to those with suboptimal timing (32.9 versus 50.9%, OR [95% CI]: 0.47 (0.26, 0.87), p = .02).Conclusions: Suboptimal ACS administration occurred in most indicated preterm births. Underutilization of rescue ACS course and a substantial rate of missed opportunities for optimal ACS administration were identified as potentially modifiable contributors to improve ACS timing.

Objectives: The objective of this study is to evaluate patterns of use and outcomes of retrievable inferior vena cava filters (rIVCF) in obstetric patients. Methods: A single center review of consecutive patients who underwent rIVCF placement during pregnancy/postpartum in 2005-2016. A pooled analysis of the relevant cases in the English literature was conducted. Results: The current cohort comprised 24 women, median age 27 [interquartile range 24-30] years. Among 10 filters placed during pregnancy, the most common indication (n = 4) was the need to withhold anticoagulation therapy before delivery, in the presence of acute thrombosis. In the postpartum period, most filters (64%, 9/14) were an adjunct to catheter-directed thrombolytic therapy. Inferior vena cava filters (IVCF)-related complications occurred in seven (29.2%). Retrieval was attempted in 21 patients (87.5%), and was technically successful in 19 (90.5%), for an overall removal rate of 79.1%. Pooled analysis of the literature (n = 98) showed comparable rates for filter removal and complications (81.6%, p = .78 and 24.2%, p = .60, respectively). Suprarenal placement (p = .12) and elective cesarean section (p = .19) did not reduce overall complication and retrieval rates. The estimated radiation dose among pregnant patients who underwent rIVCF placement without adjunct catheter directed thrombolysis (CDT) (mean 695 Gy cm2) was significantly lower than the radiation dose used in postpartum patients (1863 Gy cm2) or in pregnant patients in whom adjunct CDT was utilized (4059 Gy cm2) (p = .001 for both comparisons). Conclusions: Frequent rIVCF-related complications, radiation exposure, and removal failure call for their cautious utilization in obstetric patients. The role of suprarenal placement and elective cesarean section to improve outcomes has yet to be established. [ABSTRACT FROM AUTHOR]

Objective: To assess the maternal and neonatal outcomes following delayed diagnosis of uterine rupture (diagnosis during the early postpartum period) in comparison to women with an intrapartum diagnosis of uterine rupture.Methods: Retrospective study of electronic medical records (EMR) from 2005 to 2018 in a single large academic tertiary care. Demographic, obstetric and maternal characteristics and outcomes were retrieved and compared. Univariate, followed by multivariate analyses were applied to evaluate the association between maternal and neonatal outcomes. Only complete uterine ruptures were included. The primary outcome of this study was defined as hysterectomy rates. Secondary outcomes were maternal and neonatal morbidity parameters.Results: During the study period, 143 parturients with uterine rupture were identified from 174,189 deliveries (0.08%). Of these, 29 (20.3%) had delayed diagnosis with a median time from delivery to the operation of 4.5 hours (IQR 0.83-28 hours). Factors that were identified as independent risk factors for delayed diagnosis: an unscarred uterus (aOR 27.0, 95% CI 6.58-111.1), epidural analgesia during labor (aOR 7.9, 95% CI 2.32-27.05) and grand-multiparity (aOR 4.6, 95% CI 1.40-14.99). Maternal outcomes demonstrated that parturients with a delayed diagnosis had significantly higher rates of blood transfusions, puerperal fever, and hysterectomy (p<.001 for all). In a multivariate model, the delayed diagnosis was found to be independently associated with hysterectomy (aOR 4.90, 95% CI 1.28-19.40). There were no differences regarding to neonatal outcomes.Conclusion: Parturients with delayed diagnosis of uterine rupture have unique characteristics and poorer maternal outcomes. It is possible that awareness of this population will enable earlier diagnosis and may help improve outcomes. [ABSTRACT FROM AUTHOR]
