Maternal and perinatal infectious morbidity in term prelabor rupture of membrane according to two induction of labor protocols.

PURPOSE: The optimal labor-induction protocol in women with prelabor rupture of membranes (PROM) is unknown. Whether the management of women with a previous cesarean delivery (CD) with PROM is different remains controversial. We investigated maternal and perinatal outcomes according to two induction protocols of 24 h vs. 12 h. METHODS: In July 2021, our protocol of induction of labor in term-PROM was extended from 12 h to 24 h post-PROM. We compared obstetrical and neonatal outcomes before and after the change. A subgroup analysis of women with previous CD was performed. Results were compared using a univariate analysis. A multivariable model was described to predict neonatal intensive care unit admission (NICU) and clinical chorioamnionitis. RESULTS: The 24 h and 12 h ROM-to-induction protocol groups included 962 and 802 women, respectively. In the 24 h group, a higher proportion of women labored spontaneously (p < 0.001), the rate of chorioamnionitis was higher (p = 0.017), and the CD rate was similar. Admission to the NICU (p = 0.012), antibiotic administration (p = 0.003), and respiratory distress (p = 0.002) were also greater in the 24 h induction group. Among women with a history of CD (n = 143), the need for oxytocin (p = 0.003) and delivery by CD (p = 0.016) were lower in the 24 vs. 12 h group. CONCLUSION: Our results advocate shared decision-making in the expectant management of term-PROM. Women should be informed of the lower chance for induction and the higher risk of infections and neonatal complications with a 24-h induction approach. Longer expectant management in women with a previous CD resulted in significantly lower induction and CD rates.

The relation between low-grade fever during prolonged rupture of membranes (>12 hours) at term and infectious outcomes: a retrospective cohort study.

BACKGROUND: Intrapartum fever (>38°C) is associated with adverse maternal and neonatal outcomes. However, the correlation between low-grade fever (37.5°C-37.9°C) and adverse perinatal outcomes remains controversial. OBJECTIVE: This study aimed to compare maternal and neonatal outcomes of women with prolonged rupture of membranes (≥12 hours) at term between those with low-grade fever and those with normal body temperature. STUDY DESIGN: This retrospective study included women hospitalized in a tertiary university-affiliated hospital between July 2021 and May 2023 with singleton term and rupture of membranes ≥12 hours. Women were classified as having intrapartum low-grade fever (37.5°C-37.9°C) or normal body temperature (<37.5°C). The co-primary outcomes, postpartum endometritis and neonatal intensive care unit admission rates, were compared between these groups. The secondary maternal outcomes were intrapartum leukocytosis (>15,000/mm2), cesarean delivery rate, postpartum hemorrhage, postpartum fever, surgical site infection, and postpartum length of stay. The secondary neonatal outcomes were early-onset sepsis, 5-minute Apgar score of <7, umbilical artery cord pH<7.2 and pH<7.05, neonatal intensive care unit admission length of stay, and respiratory distress. The data were analyzed according to rupture of membranes 12 to 18 hours and rupture of membranes ≥18 hours. In women with rupture of membranes ≥18 hours, intrapartum ampicillin was administered, and chorioamniotic membrane swabs were obtained. The likelihood ratios and 95% confidence intervals were calculated for the co-primary outcomes. A multivariate logistic regression model was used to predict puerperal endometritis controlled for rupture of membranes duration, low-grade fever (compared with normal body temperature), positive group B streptococcus status, mechanical cervical ripening, cervical ripening by prostaglandins, artificial rupture of membranes, meconium staining, epidural analgesia, and cesarean delivery. A multivariate logistic regression model was used to predict neonatal intensive care unit admission controlled for rupture of membranes duration, low-grade fever, positive group B streptococcus status, mechanical cervical ripening, artificial rupture of membranes, meconium staining, cesarean delivery, and neonatal weight of <2500 g. RESULTS: This study included 687 women with rupture of membranes 12 to 18 hours and 1109 with rupture of membranes ≥18 hours. In both latency groups, the rates were higher for cesarean delivery, endometritis, surgical site infections, umbilical cord pH<7.2, neonatal intensive care unit admission, and sepsis workup among those with low-grade fever than among those with normal body temperature. Among women with low-grade fever, the positive likelihood ratios were 12.7 (95% confidence interval, 9.6-16.8) for puerperal endometritis and 3.2 (95% confidence interval, 2.0-5.3) for neonatal intensive care unit admission. Among women with rupture of membranes ≥18 hours, the rates were higher of Enterobacteriaceae isolates in chorioamniotic membrane cultures for those with low-grade fever than for those with normal intrapartum temperature (22.0% vs 11.0%, respectively; P=.006). Low-grade fever (odds ratio, 9.0; 95% confidence interval, 3.7-21.9; P<.001), artificial rupture of membranes (odds ratio, 4.2; 95% confidence interval, 1.5-11.7; P=.007), and cesarean delivery (odds ratio, 5.4; 95% confidence interval, 2.2-13.4; P<.001) were independently associated with puerperal endometritis. Low-grade fever (odds ratio, 3.2; 95% confidence interval, 1.7-6.0; P<.001) and cesarean delivery (odds ratio, 1.9; 95% confidence interval, 1.1-13.1; P=.023) were independently associated with neonatal intensive care unit admission. CONCLUSION: In women with rupture of membranes ≥12 hours at term, higher maternal and neonatal morbidities were reported among those with low-grade fever than among those with normal body temperature. Low-grade fever was associated with a higher risk of Enterobacteriaceae isolates in chorioamniotic membrane cultures. Moreover, low-grade fever may be the initial presentation of peripartum infection.

Papaverine prior to catheter balloon insertion for labor induction: a randomized controlled trial.

BACKGROUND: Catheter balloon insertion is a common method for cervical ripening and labor induction. Papaverine and its derivatives are musculotropic antispasmodic drugs that directly induce smooth muscle relaxation. Used during childbirth, these drugs have been suggested to shorten the duration of labor. OBJECTIVE: This study aimed to evaluate the effect of administering papaverine before catheter balloon insertion on changes in Bishop scores and on the labor induction-to-delivery interval. STUDY DESIGN: This randomized, double-blinded, placebo-controlled trial was conducted in a single tertiary university-affiliated hospital. Participants were admitted at term for labor induction with an initial Bishop score of ≤6. Participants were randomized to receive 80 mg intravenous papaverine or 0.9% normal saline solution within 30 minutes of Foley catheter balloon insertion. The co-primary outcomes were the difference in Bishop score from before catheter balloon insertion to after removal and the labor induction-to-delivery interval. The secondary outcomes included maternal pain and satisfaction scores, delivery within 24 hours, and neonatal outcomes. Both intention-to-treat and per-protocol analyses were performed. RESULTS: Overall, 110 women were enrolled. In the intention-to-treat analysis, the median difference in Bishop score was greater in the papaverine group than in the placebo group (5 [interquartile range, 1-11] vs 4 [interquartile range, 0-7], respectively; P=.025), and the median catheter balloon insertion-to-delivery interval was shorter in the papaverine group than in the placebo group (21 hours [interquartile range, 6-95] vs 26 hours [interquartile range, 3-108], respectively; P=.031). A higher proportion of women delivered within 24-hours in the papaverine group than in the placebo group (65.5% vs 41.8%, respectively; P=.012). Pain and satisfaction scores, delivery, and neonatal outcomes were similar between the groups. Similar results were found in the per-protocol analysis. CONCLUSION: Papaverine administration before Foley catheter balloon insertion for cervical ripening resulted in improved Bishop scores and shorter catheter balloon insertion-to-delivery intervals.

Birth outcomes associated with a natural delivery approach in a perinatal center: A comparative retrospective study.

OBJECTIVES: At our center, natural home-like delivery settings have been established in or near conventional labor wards, for the care of pregnant women who prefer little or no medical intervention during labor and birth. We compared obstetrical and neonatal outcomes of women in active spontaneous labor, between those who chose to deliver in a natural-delivery setup and those who chose a conventional setting. METHODS: This retrospective study included low-risk women who delivered at term between March 1, 2020 and December 31, 2022, in a single tertiary university affiliated medical center. Birth outcomes were compared between 124 women who delivered by natural birth (the study group) and 244 who gave birth in a conventional setting (the control group). RESULTS: No cesarean deliveries were performed in the study group, compared to 18 (7.4%) of the control group, p = 0.004. Intrapartum fever, postpartum hemorrhage, and uterotonic administration were similar between the groups. For the study compared to the control group, breastfeeding was more common (71.3% vs. 12.3%, p < 0.001), analgesia administration within 48 h delivery was lower (4.1% vs. 10.7%, p = 0.033), and maternal and neonatal length of hospitalization were shorter. Of the women initially admitted to the natural-delivery room, 14 (11.5%) were transferred to a conventional-delivery room. CONCLUSIONS: Birth in a hospital natural-delivery setting was associated with increased likelihood of vaginal birth, increased immediate breastfeeding and breastfeeding at discharge, and lower postpartum pain.

The role of the cerebroplacental ratio in predicting pregnancy outcomes at 40-42 gestational weeks: a prospective observational trial.

PURPOSE: The cerebroplacental ratio is a sonographic tool used to predict poor pregnancy outcomes. Data are insufficient regarding its use in postdate pregnancy. We evaluated the cerebroplacental ratio's prediction of unfavorable pregnancy outcomes in women at 40-42 weeks gestation with normal amniotic fluid index. METHODS: This prospective observational study included 101 women with low-risk singleton pregnancy and gestational age > 40 weeks who delivered in a university affiliated hospital during 2020-2021. The middle cerebral artery pulsatility index, the umbilical artery pulsatility index, and the cerebroplacental ratio, which is their quotient, were compared between women with favorable and unfavorable pregnancy outcomes. The latter included: meconium-stained amniotic fluid, cesarean or vacuum-assisted delivery due to pathological cardiotocography (category 2 or 3), 5-min Apgar score < 7, umbilical cord pH < 7.1, neonatal intensive care unit admission, and neonatal death. RESULTS: Fetal Doppler, performed at a median gestational age of 40.3 (40.0-41.6), did not differ between 75 (74.3%) women with favorable obstetrical outcomes and 26 (25.7%) with unfavorable outcomes. In multivariate analysis, advanced maternal age and a history of a cesarean section were correlated with unfavorable outcomes, while Doppler indices were not found to be predictive. Among women at 41-42 weeks' gestation, for those with intrapartum fetal monitor category 2-3 vs. category 1, the mean umbilical artery pulsatility index was higher: 0.92 ± 0.34 vs. 0.71 ± 0.11 (p = 0.044). CONCLUSION: According to the study results, fetal Doppler indices, including the cerebroplacental ratio, are not predictive of unfavorable outcome in women with pregnancies exceeding 40 weeks. Larger prospective studies are needed.

Relations between maternal height, shoe size, and the success of vaginal delivery in birth weight over 4000 g.

OBJECTIVE: Macrosomia is associated with increased risk of fetal and maternal complications such as trauma during birth, cesarean delivery, postpartum hemorrhage, and shoulder dystocia. Sonographic estimation of fetal weight is imprecise particularly in excessively large fetuses, prompting the need for additional measures to assess the feasibility of vaginal delivery of a macrosomic newborn and thus improve prenatal consultation. MATERIALS AND METHODS: This retrospective case-control study included women who delivered a singleton macrosomic newborn (birth weight>4,000 g), either vaginally (N = 762) or by urgent cesarean delivery during labor (N = 109). Using multivariable analysis, we examined correlations of maternal height≥170 cm and shoe size≥40 with successful vaginal delivery. RESULTS: Women who delivered vaginally had lower mean intrapartum BMI (p < 0.001) and lower rate of gestational diabetes (p = 0.003). Women with a shoe size≥40 were 2.2 times more likely to give birth vaginally. Cesarean section rate was 5.9 % among women with height≥170 cm and shoe size≥40; and 16.5 % among women with height<170 cm and shoe size<40. Multivariable analysis, adjusted for gestational diabetes, parity, and BMI, revealed that shoe size≥40 and maternal height≥170 cm correlated with success in vaginal delivery, OR = 3.1 (95%CI 1.3-7.3, p = 0.009). CONCLUSION: Shoe size and maternal height may help predict success of vaginal birth of the macrosomic newborns.

The utility of inpatient anemia workup in hemoglobin < 10 g/dL diagnosed randomly in the third trimester: a retrospective study.

PURPOSE: About 40% of pregnant women are anemic and at an increased risk for complications. We examined the efficacy of inpatient anemia workup and treatment in pregnant women diagnosed with moderate-severe anemia (hemoglobin < 10 mg/dL), during hospitalization in the late second-trimester and third-trimester. METHODS: This retrospective study, conducted between March 2020 and November 2022, included women at ≥ 24 gestational weeks who were hospitalized due to various indications and diagnosed with anemia (hemoglobin < 10 mg/dL). The study group comprised women who underwent an inpatient anemia workup and initiation of anemia treatment. The comparison group comprised women who did not undergo an inpatient anemia investigation. The primary outcome was the rate of pre-delivery hemoglobin > 11 g/dL. RESULTS: The most frequent etiology of anemia in the study group (n = 188) was iron-deficiency anemia (30.2%), followed by mixed anemia of iron, folate and vitamin-B12 deficiencies (20.7%). In the study vs. the comparison group (n = 179), the rate of pre-delivery hemoglobin > 11 g/dL was higher, and the increase in hemoglobin from intervention to delivery was greater. The ideal timing for anemia intervention for maximizing the increase in pre-delivery hemoglobin was 6-weeks or more prior to delivery. The rates of postpartum hemorrhage and blood transfusions were similar. The rate of postpartum hemoglobin < 10 g/dL was lower in the study than the comparison group. CONCLUSION: Inpatient anemia investigation and treatment resulted in higher peri-delivery hemoglobin. In women randomly diagnosed with anemia at hospitalization, the rate of pre-delivery hemoglobin > 11 g/dL was increased among those who underwent a simple anemia investigation and treatment initiation.

Colposcopy-A Valuable Diagnostic Tool for Pregnant Women With Unexplained Vaginal Bleeding.

OBJECTIVES: We aimed to examine the diagnostic value of colposcopy in a large cohort of pregnant women with unexplained vaginal bleeding during the second or third trimester. MATERIALS AND METHODS: This retrospective study included women who underwent colposcopy due to vaginal bleeding in the second and third trimesters during 2012-2022 at a tertiary care hospital. Demographics, obstetric data, bleeding characteristics, colposcopy results, cervical cytology testing, a sonogram directed at the placenta, and birth details were collected. RESULTS: In total, 364 women were included. The mean maternal age was 29.7 years and the mean gestational age at examination was 30.7 weeks. Vaginal bleeding was mild in 80.8%, moderate in 14.6%, and severe in 4.7%. Only 3.3% had been vaccinated against human papilloma virus and 25.5% underwent a Pap smear study before pregnancy. Colposcopy diagnosed the bleeding source in 83 women (22.8%). The colposcopic examination revealed vaginal bleeding due to contact bleeding from ectropion in 46 (12.6%), a decidual/cervical polyp in 37 (10.2%), acetowhite epithelium in 12 (3.3%), herpes genetalis in 2 (0.5%), and bleeding from vaginal varices in 2 (0.5%). Of those who were recommended a follow-up examination after the postpartum period, only 49.1% completed such.Among women with compared to without postcoital bleeding ( N = 72), the risk of abnormal colposcopic findings was higher (24 [33.3%] vs 54 [19.7%], p = .017) and the rate of abnormal Pap smear was higher (7 [13.2%] vs 7 [3.2%], p = .008). CONCLUSIONS: Colposcopy can be a valuable diagnostic tool for women with unexplained vaginal bleeding in the second or third trimester.

The Effect of Maternal Lower Limb Compression on Amniotic Fluid Index, Uteroplacental Perfusion, and Fetal Blood Flow in Isolated Oligohydramnios.

INTRODUCTION: The aim of this study was to examine the efficacy of pneumatic compression of the maternal lower extremities in increasing the amniotic fluid index (AFI) in pregnancies complicated by isolated oligohydramnios. METHODS: Women with isolated oligohydramnios (AFI <5 cm) at 32-41 weeks of pregnancy were connected to a sequential compression device for 60 min. Prior and after the application, AFI and the pulsatility index (PI) of a number of arteries were measured. RESULTS: The median (interquartile range) maternal age of the 21 women included was 29 years (26.50-32.00), the median parity was 1 (1-2), and the median gestational age at intervention was 37.60 weeks (37.00-39.40). The median AFI increased after the application from 4.00 (3.62-4.50) to 6.08 cm (4.90-7.03) (p < 0.001). The median PI of the fetal renal artery decreased from 2.30 (2.01-2.88) to 2.26 (1.68-2.71) (p = 0.01). The hourly fetal urine production did not increase. Changes were not significant in the PI of the umbilical artery, the middle cerebral artery, and the bilateral uterine arteries. CONCLUSION: Short-term activation of pneumatic compression on maternal lower extremities could increase the AFI in women with isolated oligohydramnios.

The Utility of Maternal TORCH Screening Due to Obstetrical Indications in Detecting Congenital Infections: A Retrospective Observational Study.

BACKGROUND: The diagnostic yield of TORCH screening for obstetrical indications is unclear. We evaluated TORCH testing results among women with intrauterine growth restriction (IUGR), polyhydramnios and oligohydramnios; and associations with congenital infections in neonates. METHOD: This retrospective single-center study included all the women diagnosed with IUGR, polyhydramnios or oligohydramnios who underwent serological TORCH testing during 2010-2019. TORCH screening included Toxoplasma, cytomegalovirus (CMV), rubella IgM and IgG. The data, which were cross-referenced with data of neonates with congenital TORCH infections during the same period, included indications for neonatal testing, sonographic findings and neonatal ophthalmologic and hearing findings. RESULT: Six women of 771 (0.8%) were diagnosed with primary TORCH infection: 4 (0.5%) with toxoplasmosis, and 2 (0.3%) with CMV. None had a confirmed congenital infection. The rates of positive maternal TORCH screening in IUGR and polyhydramnios were 2.1% and 0.6%, respectively. Maternal TORCH infection was not identified in any woman with oligohydramnios or severe polyhydramnios. None of the neonates with congenital infection were screened for TORCH during pregnancy due to polyhydramnios, oligohydramnios or IUGR. Among the neonates with congenital CMV, the most common indication for performing neonatal CMV polymerase chain reaction was suspected primary maternal infection during pregnancy due to symptomatic CMV. No incidences of congenital rubella were noted in the last decade in our medical center. CONCLUSION: Our results suggest that routine TORCH screening in pregnancies complicated with IUGR, polyhydramnios or oligohydramnios should be avoided. Suggestive maternal symptoms and specific fetal sonographic features should prompt testing for CMV and Toxoplasma infection.

Bacteriology and clinical outcomes of urine mixed bacterial growth in pregnancy.

INTRODUCTION AND HYPOTHESIS: The objective was to analyse the risk of significant bacteriuria in repeat urine cultures from pregnant women, following initial mixed bacterial results. METHODS: This retrospective study examined maternal characteristics and clinical features of women who repeated urine cultures due to previous mixed cultures results. RESULTS: Of 262 women included, 80 (30.5%) had negative cultures and 125 (47.7%) had mixed bacterial growth in their repeat cultures. Positive results (≥104 CFU/ml of a urinary pathogen) were obtained for 57 women (21.8% [95% CI 17.1-27.0]). For 37 (14.1%), the repeat specimen grew 104-105 CFU/ml of microorganisms; whereas for 20 women (7.6% [95% CI 4.9-11.3]), it grew ≥105 CFU/ml. Among women with positive (>104 CFU/ml) compared with those with negative or mixed growth, rates of urinary symptoms were higher (38.6% vs 23.4%, p=0.028), abnormal dipstick results (49.1% vs 21.0%, p<0.001) and hydronephrosis, as demonstrated by renal ultrasound (12.3% vs 2.0, p=0.003). In a multivariate logistic regression analysis, hydronephrosis was associated with the occurrence of a positive repeat culture (aOR = 10.65, 95% CI 2.07-54.90). The sensitivity and specificity for predicting a repeat urine culture with ≥105 CFU/ml were 12.9% and 94.3% respectively, for urinary symptoms; and 19.7% and 97.4% respectively, for abnormal dipstick results. CONCLUSIONS: Mixed bacterial growth might represent a true urinary tract infection in a considerable proportion of women who are symptomatic and have an abnormal dipstick urinalysis.

Antibiotic treatment of women with isolated intrapartum fever vs clinical chorioamnionitis: maternal and neonatal outcomes.

BACKGROUND: Clinical chorioamnionitis refers to the presence of maternal fever (≥38°C) and at least 2 clinical signs: (1) maternal tachycardia (>100 bpm), (2) fetal tachycardia (>160 bpm), (3) maternal leukocytosis >15,000/mm2, (4) purulent vaginal discharge, and (5) uterine tenderness. Few data exist to guide the appropriate management of women with isolated intrapartum fever in the absence of other clinical signs suggesting chorioamnionitis. OBJECTIVE: This study compared maternal and neonatal infectious outcomes and microbiological outcomes between women with isolated intrapartum fever and women with clinical chorioamnionitis. STUDY DESIGN: This 10-year retrospective study included all the laboring women at our institution, at ≥34 weeks of gestation, with a singleton pregnancy and body temperature of ≥38.0°C, with or without other evidences of infection. According to our department protocol, women with isolated intrapartum fever received intravenous ampicillin, whereas women with clinical chorioamnionitis received intravenous ampicillin plus gentamicin. The primary outcome was puerperal endometritis, compared between women with isolated intrapartum fever (treated with ampicillin) and women with clinical chorioamnionitis (treated with ampicillin plus gentamicin). The secondary maternal outcomes consisted of (1) maternal clinical outcomes, such as cesarean delivery, surgical site infection, postpartum hemorrhage, and postpartum length of stay, and (2) microbiological studies, including positive chorioamniotic membrane swabs and blood culture. Among the secondary neonatal outcomes were early-onset sepsis, neonatal intensive care unit admission, and length of stay. Of note, 2 multivariate logistic regression models were created. A model aimed to predict puerperal endometritis controlled for gestational age of >41 weeks, diabetes mellitus, obesity, positive group B streptococcus status, rupture of membrane ≥18 hours, meconium staining, positive chorioamniotic membrane swabs, cesarean delivery, and empiric postdelivery antibiotic administration. A model aimed to predict neonatal early-onset sepsis controlled for gestational age of 34 to 37 weeks, positive group B streptococcus status, rupture of membrane ≥18 hours, and positive chorioamniotic membrane swabs. RESULTS: Overall, 458 women met the inclusion criteria. Compared with women with clinical chorioamnionitis (n=231), women with isolated intrapartum fever (n=227) had higher rates of puerperal endometritis (3.9% vs 8.8%; P=.03), early-onset sepsis (0.4% vs 4.4%; P=.005), positive chorioamniotic membrane swabs (46.3% vs 63.9%; P<.001), and ampicillin-resistant Escherichia coli (35.5% vs 48.9%; P=.033). The rate of group B streptococcus-positive chorioamniotic membrane swabs was similar between the groups. In a subanalysis of women with negative or unknown group B streptococcus status, the puerperal endometritis and neonatal early-onset sepsis rates were higher among women with isolated intrapartum fever than women with suspected chorioamnionitis (8.7% vs 3.3% [P=.041] and 4.1% vs 0% [P<.001], respectively). In 2 multivariate analysis models, among women with isolated intrapartum fever treated with ampicillin compared with those with clinical chorioamnionitis treated with ampicillin and gentamicin, the odds ratio of antibiotic treatment of endometritis was 2.65 (95% confidence interval, 1.06-6.62; P=.036), and the odds ratio of neonatal early-onset sepsis was 8.33 (95% confidence interval, 1.04-60.60; P=.045). CONCLUSION: Women with intrapartum fever, with or without other signs of infection, were at increased risk of maternal and neonatal complications. The use of ampicillin as a sole agent in isolated intrapartum fever might promote ampicillin-resistant E coli growth in the chorioamniotic membranes and consequently lead to puerperal endometritis and early-onset sepsis. In this context, a broad-range antibiotic should be considered.

Implementation of French AmbUlatory Cesarean Section (FAUCS): Establishment of a Learning Curve and Short-term Outcomes.

BACKGROUND: The French AmbUlatory Cesarean Section (FAUCS) technique was introduced to the Galilee Medical Center in September 2021. FAUCS was performed electively for interested women who meet the criteria. OBJECTIVES: To evaluate the learning curve of senior surgeons performing FAUCS, the procedure short-term outcomes, and complications. METHODS: This retrospective study included 50 consecutive women who underwent FAUCS from September 2021 until March 2022 at our facility. Preoperative, intraoperative, postoperative, and demographic data were retrieved from patient electronic charts. RESULTS: The mean duration of surgery was 53.26 ± 11.62 minutes. This time decreased as the surgical team's experience increased: from a mean 58.26 ± 12.25 minutes for the first 15 procedures to a mean 51.17 ± 9.73 minutes for subsequent procedures. The mean visual analogue scale score for 24 hours was 1.08 ± 0.84 (on a 10-point scale). The rate of neonatal cord pH < 7.2 was 6%, and there were 11.3% cases of vacuum assisted fetal extraction. In total, 44% of the women were able to mobilize and urinate spontaneously by 4-6 hours. Complications included bladder injury (n=1), endometritis (n=1), and incisional hematoma (n=1). Overall, the maternal satisfaction rate was high; 94% of the women would recommend FAUCS to others. CONCLUSIONS: FAUCS is a feasible procedure with a high satisfaction rate. Following the first 15 procedures performed by one surgical team, the operative time decreased considerably. Further randomized controlled studies are needed to compare this procedure to regular cesarean section and evaluate neonatal outcomes.

Azathioprine and 6-mercaptopurine-induced intrahepatic cholestasis of pregnancy: Case report and review of the literature.

OBJECTIVE: Azathioprine, a prodrug of 6-mercaptopurine (6-MP), is used in the treatment of inflammatory bowel disease and may be continued during pregnancy. Acute cholestatic liver injury has been reported to occur with azathioprine. We aimed to examine azathioprine related cholestasis effect on pregnancy complications and outcome. CASE REPORT: We present a unique case of 6-MP-induced severe intrahepatic cholestasis of pregnancy (ICP) that required meticulous combined therapy including plasma exchange. The symptoms resolved following 6-MP withdrawal. A literature review revealed 11 pregnancies complicated by early-induced severe ICP among women treated with azathioprine or 6-MP. CONCLUSION: We recommend weekly bile acid level tests for pregnant women treated with azathioprine or 6-MP, beginning early in the second trimester of pregnancy, and the prompt discontinuation of treatment upon establishment of an ICP diagnosis.

Time to reconsider antibiotic prophylaxis in women with prolonged rupture of membranes: The trend of Enterobacteriaceae in peripartum infections.

OBJECTIVE: The proportion of neonatal early-onset sepsis (EOS) by gram-negative bacteria has increased. The authors examined bacterial distribution in the amniotic membrane cultures of women with peripartum fever (PPF) and related perinatal outcomes. METHODS: This retrospective study covered the period 2011 to 2019. The primary outcomes were Enterobacteriaceae-positive birth culture rates in women with PPF and the trend of ampicillin resistance. Maternal and neonatal outcomes were compared between women with group B Streptococcus (GBS) and Enterobacteriaceae-positive isolates. Bacterial distribution was also compared according to rupture of membrane (ROM) duration. RESULTS: Among 621 women with PPF, the positive birth culture rate was 52%. Increasing prevalences of ampicillin-resistant Enterobacteriaceae (81%) were noted. Positive birth cultures were associated with maternal bacteremia (P = 0.017) and neonatal EOS (P = 0.003). Prolonged ROM ≥18 h was associated with increased risk for Enterobacteriaceae-positive cultures, while intrapartum ampicillin and gentamicin were associated with lower risk. Enterobacteriaceae-positive compared with GBS-positive birth cultures were associated with adverse maternal and neonatal outcomes. CONCLUSION: Positive birth cultures were related to maternal bacteremia and neonatal sepsis. Adverse outcomes were more prevalent among women with Enterobacteriaceae-positive versus GBS-positive birth cultures. Prolonged ROM is a risk factor for Enterobacteriaceae-positive birth cultures among women with PPF. Antibiotic prophylaxis treatment for prolonged ROM should be reconsidered.

Maternal and Cord Anti-SARS-CoV-2-Spike IgG following COVID-19 Vaccination versus Infection during Pregnancy: A Prospective Study, Israel October 2021-March 2022.

OBJECTIVE: Defining how pregnant women respond to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and vaccination is critical to optimize vaccination strategies that protect mother and infant at the epidemic. This study aimed to compare anti-SARS-CoV-2-spike immunoglobulin G (IgG) of vaccinated versus infected women and to determine the optimal timing of maternal vaccination during pregnancy at the time of epidemic. STUDY DESIGN: We collected maternal/cord blood at delivery (October 2021-March 2022) and measured anti-SARS-CoV-2-spike IgG geometric mean concentrations (IgG-GMCs) using a quantitative immunoassay. We compared groups according to timing and number of doses and correlated maternal and fetal IgG levels. We described the proportion of women with IgG levels above the 150 AU/mL positivity threshold according to the timing of infection/vaccination and performed a subanalysis for maternal IgG-GMC levels pre- and during the Omicron wave. RESULTS: We included 238 vaccinated women, 125 who received two doses and 113 three doses, and 48 unvaccinated infected women. All groups infected/vaccinated in the second or third trimester had an IgG-GMC above the positivity threshold. Third-trimester vaccination (second/third dose) resulted in higher maternal and cord-blood IgG-GMC compared to the second trimester (maternal-IgG: 102,32 vs. 4,325 AU/mL, p < 0.001; cord-IgG: 12,113 vs. 8,112 AU/mL, p < 0.001). Compared with infected-only women, a higher proportion of vaccinated women with ≥2 doses and their newborns had IgG levels above the positivity threshold at all time points. In vaccinated women, there were higher maternal IgG-GMC levels during the Omicron wave than pre-Omicron. CONCLUSION: At the time of epidemic, receiving an additional COVID-19 vaccine dose in the third trimester resulted in a higher IgG-GMC compared to the second trimester. Relatively higher levels of maternal and cord IgG-GMC were achieved following vaccination than infection. Women infected during or before the first trimester might benefit from an additional third-trimester dose to prevent peripartum infection and to passively immunize their newborn. The higher levels of maternal IgG-GMC in the Omicron period are suggestive of hybrid immunity. KEY POINTS: · Higher maternal anti-SARS-IgGs in vaccinated → infected.. · Higher cord anti-SARS-IgGs in vaccinated → infected.. · Third-trimester vaccine resulted in high-cord IgG levels..

Single versus dual antibiotic regimen in women with term prolonged rupture of membranes and intrapartum fever: a retrospective study.

OBJECTIVES: The impact of E. coli in causing peripartum infections has been increasing due to rising ampicillin resistance. In this study, we compared maternal and neonatal outcomes of women with prolonged rupture of membranes (ROM >18h) and intrapartum fever, according to two antibiotic regimens they received, and describe the bacterial distribution focusing on risk factors for Enterobacteriaceae-related infectious morbidity. STUDY DESIGN: This 10-year retrospective study of women with ROM >18h and intrapartum fever included 62 women who were treated with ampicillin and gentamicin due to suspected intraamniotic infection and 79 without these signs who were treated with ampicillin alone. The primary outcomes were endometritis and neonatal early-onset sepsis (EOS) rates. Outcomes were compared using univariate and multivariate analyses. RESULTS: Among women who received ampicillin alone compared with dual therapy, rates were higher of endometritis (16.5% vs. 3.2%, p<0.001), neonatal early onset sepsis (7.5% vs. 0%, p=0.03), Enterobacteriaceae positive placental swab culture (67.9% vs. 15.7%, p<0.001), and histopathological subchorionitis (25.3% vs. 8.0%, p=0.008). Over 83% of Enterobacteriaceae isolates were ampicillin-resistant. Gestational age at delivery >41 weeks, meconium at delivery, ROM >24h and treatment with a single antibiotic agent were associated with the presence of a positive Enterobacteriaceae placental swab culture. CONCLUSION: Ampicillin compared to dual treatment in women with prolonged ROM and fever might promote the growth of ampicillin-resistant Enterobacteriaceae (including E.coli) and increase risks of maternal and neonatal infectious morbidity.

Digital vs speculum-guided catheter balloon insertion for cervical ripening in multiparas: a randomized controlled trial.

BACKGROUND: Catheter balloon insertion into the maternal uterine cervix is routinely speculum guided; digital insertion has been reported, but it was not found to be more tolerable among nulliparas. OBJECTIVE: In a cohort of multiparas, we aimed to evaluate maternal pain, the induction to delivery interval, and maternal satisfaction with digital insertion vs speculum-guided placement of a Foley catheter balloon for labor induction. STUDY DESIGN: This randomized trial was conducted at a single, tertiary, university-affiliated hospital. The participants were multiparas (parity ≥1) and were admitted at term for labor induction with a Bishop score <6. They were randomized to 2 groups, namely the digital insertion and the speculum-guided Foley catheter insertion groups. An intention-to-treat analysis was performed. The co-primary outcomes were visual analog scale scores (0-10) and induction to delivery intervals. Secondary outcomes were procedure duration, maternal satisfaction, cervical ripening (Bishop score ≥6), delivery within 24 hours, infection rate, and neonatal outcomes. RESULTS: A total of 50 women were analyzed for each study group. For the digitally inserted vs speculum-guided insertion group, the median visual analog scale score at catheter insertion was lower (4; range, 0-10; vs 7; range, 0-10; P<.001), and the induction to delivery interval was similar. For the digitally inserted vs speculum-guided insertion group, the median maternal satisfaction score was greater (5; range 3-5; vs 4; 1-5; P=.01), and the median procedure duration was shorter (2.1; range, 1.4-5.3 minutes vs 3.0; range, 1.4-5.0; P<.001). In the multivariate analysis, digital insertion (P=.009) and increased parity (P=.001) independently decreased the visual analog scale score. Cervical ripening, the maternal infection rate, and the neonatal outcomes did not differ significantly between the groups. CONCLUSION: Digital insertion of a Foley catheter balloon for cervical ripening in multiparas is less painful and quicker than speculum-guided insertion. It is also not inferior in terms of successful cervical ripening.

Clinical implications of the 100-g oral glucose tolerance test in the third trimester.

PURPOSE: The clinical implications of gestational diabetes mellitus (GDM) diagnosed in the third trimester are not well established and controversy continues regarding the performance of diagnostic tests beyond 28-week gestation. This study aimed to evaluate the incidence of abnormal third trimester oral glucose tolerance test (OGTT) results in women at high risk and to compare the obstetric and neonatal outcomes with those of women with normal OGTT results. METHODS: The study included 372 women who completed late (>29 weeks) 100-g OGTT due to suspected fetal macrosomia, polyhydramnios or a personal risk factor for GDM, diagnosed according to the Carpenter & Coustan criteria. Women with only one abnormal OGTT value were diagnosed with GDM by abnormal glucose follow-up and analyzed separately. Obstetric and neonatal outcomes were compared between the GDM and the non-GDM groups. RESULTS: GDM was diagnosed in 85/372 (22%) women, including 35 (59.3%) women with one abnormal OGTT value who were later diagnosed with GDM. Of 200 women who had a normal 1-h 50-g glucose challenge test at 24-28 weeks, late GDM was diagnosed in 33 (16.5%). Seventy-six (89.5%) of those with GDM were treated by dietary therapy and 9 (10.5%) by pharmacological therapy. Among women with GDM, large-for-gestational-age fetuses, labor induction and elective cesarean section were more prevalent than for those without GDM. Significant differences were not found between the groups in macrosomia and neonatal outcomes. CONCLUSIONS: The performance of OGTT in women with risk factors during the third trimester should be considered following further prospective trials.
