Treatment with beta-agonist tocolytics preceding external cephalic version (ECV) attempt increases success rates. Most studies have focused on intravenously and orally administered beta-agonists, while other administration routes including intramuscularly (IM) and subcutaneously (SC) are understudied. The aim of this study was to compare the efficacy of IM ritodrine to SC salbutamol given prior to ECV.A retrospective study of patients who underwent ECV between 1/2012 and 12/2019 at two medical centers. We compared patients undergoing ECV following IM ritodrine versus SC salbutamol. We matched the two groups by parity and placental location. Maternal, pregnancy, ECV procedure and neonatal characteristics were compared.Overall, 601 women were included in each group. Median maternal age and amniotic fluid index (AFI) were lower in the Ritodrine group (27 vs. 32 years, P0.001, 11 vs. 15 AFI cm, P0.001, respectively). The median gestational age at ECV was higher in the Ritodrine group (38Intramuscular ritodrine significantly improved the success rate of ECV compared to SC salbutamol, and both drugs were safe and acceptable before ECV.

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

OBJECTIVE To study maternal and intrapartum factors associated with adverse neonatal outcome in deliveries complicated by meconium-stained amniotic fluid (MSAF). METHODS A retrospective cohort study of all women with singleton gestations undergoing trial of labor with MSAF during 2011-2020. Deliveries with adverse neonatal outcome were compared with deliveries without. RESULTS Overall, 11 329 were included; 376 (3.3%) neonates were diagnosed with adverse neonatal outcomes. Multivariable regression analysis underlined the following factors as independently associated with composite adverse neonatal outcome: pregestational diabetes (odds ratio [OR] 3.21, 95% confidence interval [CI] 1.09-9.43, P = 0.031), polyhydramnios (OR 2.14, 95% CI 1.33-3.44, P = 0.002), fever (OR 2.52, 95% CI 1.67-3.80, P

Although shoulder dystocia (ShD) is associated with fetal macrosomia and vacuum-assisted delivery (VAD), the independent role of the latter in the occurrence of ShD is yet to be completely elucidated, as it is difficult to study its true independent contribution to ShD formation in the presence of many confounding factors. Therefore, we aimed to study whether VAD is independently associated with an increased risk for ShD among macrosomic newborns. A retrospective cohort study from a single tertiary medical center including all women who delivered vaginally a macrosomic infant during 2011–2020. We allocated the study cohort into two groups: (1) VAD (2) spontaneous vaginal deliverys, and analyzed risk factors for ShD. A multivariate regression analysis was performed to identify determinants independently associated with ShD occurrence. Of 2,664 deliveries who met the study inclusion criteria, 118 (4.4%) were VAD. The rate of ShD in the entire cohort was 108/2664 (4.1%). The following factors were more frequent among the VAD group: no previous vaginal delivery [odds ratio (OR) 2.4 (95% confidence interval (CI) 1.4–4.0, p

Objectives An international diagnostic criterion for amniotic fluid embolism (AFE) diagnosis has recently been published. Data regarding subsequent pregnancies is scarce. We sought to implement recent diagnostic criteria and detail subsequent pregnancies in survivors. Methods A case series of all suspected AFE cases at a tertiary medical center between 2003 and 2018 is presented. Cases meeting the diagnostic criteria for AFE were included. Clinical presentation, treatment, and outcomes described. Pregnancy outcomes in subsequent pregnancies in AFE survivors detailed. Results Between 2003 and 2018 14 women were clinically suspected with AFE and 12 of them (85.71%) met the diagnostic criteria for AFE. Three cases occurred during midtrimester dilation and evacuation procedures, and the remaining occurred in the antepartum period. Of the antepartum cases, mode of delivery was cesarean delivery or vacuum extraction for expedited delivery due to presentation of AFE in 8/9 cases (88.88%). Clinical presentation included cardiovascular collapse, respiratory distress and disseminated intravascular coagulopathy (DIC). Heart failure of varying severity was diagnosed in 75% (9/12) cases. Composite maternal morbidity was 5/12 (41.66%), without cases of maternal mortality. 11 subsequent pregnancies occurred in four AFE survivors. Pregnant women were followed by a high-risk pregnancy specialist and multidisciplinary team if pregnancy continued beyond the early second trimester. Six pregnancies resulted in a term delivery. No recurrences of AFE were documented. Conclusions Use of a diagnostic criterion for diagnosis of AFE results in a more precise diagnosis of AFE. Nevertheless, the accuracy of clinical diagnosis is still high. Subsequent pregnancies were not associated with AFE recurrence.

Among deliveries34 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 gestations34 weeks.A retrospective cohort study including all women who underwent either ECD or VAD at the second stage of labor between 30°Of the 153,672 live singleton deliveries during the study period, 2871 (1.9%) delivered before 34°Cesarean delivery during the second stage of labor of gestations34 weeks was associated with a higher rate of lower Apgar scores and longer length of stay.Delivery by second stage CD of premature neonates34 weeks is associated with a higher rate of lower Apgar score.

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°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°Overall, there were 529/17,709 (3.0%) IO cases. IO was associated with maternal age25 years (OR [95% CI] 1.62 (1.20-2.20),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.Induction of labor in gestations complicated by IO at 36 weeks gestational age is associated with an increased risk for adverse neonatal outcome.

While the immediate effects of pregnancy on aortic dimension in patients with Marfan syndrome (MFS) have been evaluated, the late effects of subsequent pregnancies in these patients are less known. For this purpose, we evaluated 2 groups of women with MFS who were under specialized care in our institution. Group A included 23 women with MFS who experienced 55 pregnancies; group B included 12 nulliparous MFS patients. Patients in group A were similar in age (36.13 ± 5.6 years vs. 34.25 ± 6.54 years, p = 0.41) and follow-up time (group A 6.05 ± 3.56 years and group B 4.92 ± 3.37 years, p = 0.37). Baseline aortic root diameters as well as the aortic root diameters at follow-up visits were similar between groups (35.60 ± 4.42 vs. 35.08 ± 3.82 mm, p = 0.73, and 37.57 ± 4.66 vs. 37.33 ± 4.83 mm, p = 0.89, respectively). The aortic root diameter increased by 0.5 (0, 2) mm in group A and 1 (0, 4.5) mm in group B (p = 0.54). The rate of aortic dilation per year of follow-up was similar between the groups (0.34 ± 0.52 mm/year in group A vs. 0.55 ± 0.75 mm/year in group B [p = 0.52]). Chronic medical treatment was similar in both groups. Patients in both groups were treated similarly with β-blockers, angiotensin-converting enzyme inhibitors, and angiotensin II receptor blockers. In summary, subsequent pregnancies in patients with MFS were not associated with an increase in the rate of aortic root dilation in these patients.

Objective To compare pain during laminaria insertion after lidocaine spray versus placebo spray anesthesia in women about to undergo a surgical abortion procedure. Study design A double blind, randomized, placebo-controlled trial of women at 12–24 weeks gestation one day prior to surgical uterine evacuation procedure. Participants received lidocaine 10% or placebo (saline 0.9%) spray to the endocervix and ectocervix two minutes before laminaria insertion. The primary outcome was participants’ pain score immediately after initial laminaria insertion, measured using a 10 cm visual analog scale (VAS). Secondary outcomes included scores at speculum removal and 15 min after speculum insertion. Results From 7/2016 through 8/2018, we enrolled 68 and 66 women to the lidocaine and placebo groups, respectively. Baseline characteristics were similar in both groups. The primary outcome did not differ between lidocaine and placebo groups (median VAS 2.0 vs. 2.0 respectively, p = 0.69). Reported VAS after speculum removal and 15 min from speculum insertion were similar in the lidocaine and placebo groups (median 2.0, p = 0.99; median 1.0 vs. 1.5 respectively, p = 0.32). In multivariate analyses, lidocaine use was associated with decreased VAS score at 15 min from speculum insertion [95%CI −0.96 (−1.74 to −0.18), p = 0.016]. Reported VAS ≥7 at 1st laminaria insertion did not differ between lidocaine and placebo groups (5.88% vs. 10.61% respectively, p = 0.362). Conclusion In women scheduled for laminaria insertion prior to surgical uterine evacuation at 12–24 weeks gestation, topical application of lidocaine spray to the cervix before insertion did not result in lower reported pain as compared with placebo. Implications Our results imply that physicians should not use topical application of lidocaine spray to the cervix before laminaria insertion to reduce women’s pain. Continued efforts must be made to find means to relieve pain by using simple, effective analgesia or adjusting the technique, and not using a tenaculum whenever possible.

Third stage placental complications (TSPC) including partially or complete retained placenta, are a common obstetric complication. Previous studies have underlined risk factors for TSPC in heterogenous populations of women, whereas data regarding primigravid term women are scarce. We aimed to identify the factors associated with TSPC in this subset of parturients.A retrospective cohort study including all primigravid women who delivered vaginally a term, live-singleton neonate between 2011 and 2019. Women who underwent revision of the uterine cavity due to TSPC were compared with those who did not. Univariate and multivariate regression analyses were performed in order to identify the risk factors for TSPC.Overall, 16,867 deliveries met the study inclusion criteria. Of those, 1097 (6.5%) deliveries were complicated by TSPC. Women with TSPC were older (p 0.001) and with a higher proportion of lateral and fundal placental location (p 0.001). In a multivariate regression analysis, the following factors were positively independently associated with TSPC: maternal age (aOR [95% CI] 1.26 (1.17-1.36), p 0.001), the use of assisted reproduction technologies (aOR [95% CI] 1.26 (1.06-1.49), p = 0.007), preeclampsia (aOR [95% CI] 3.39 (1.89-6.10), p 0.001), thrombocytopenia (aOR [95% CI] 1.83 (1.34-2.48), p 0.001), oxytocin administration (aOR [95% CI] 1.29 (1.12-1.48), p 0.001) and longer second stage duration (aOR [95% CI] 1.03 (1.003-1.05), p = 0.02). Fetal male gender was negatively associated with TSPC (aOR [95% CI] 0.80 (0.70-0.92), p = 0.002).We have identified multiple independent risk factors for TSPC among primigravid women. This information can aid in patient counseling and delivery management in these subset of parturients.

The risk of cesarean delivery after a successful external cephalic version for breech presentation is higher as compared with fetuses in cephalic presentation. However, the role of the time interval between version attempt to delivery on the risk for cesarean delivery is unclear. We aimed to study the effect of the time interval from a successful external cephalic version to delivery on the risk for cesarean delivery and assess factors associated with cesarean delivery after a successful version. We conducted a multicenter, retrospective cohort study, including all successful external cephalic version at two medical centers between 2011 and 2019. We compared patient baseline characteristics, obstetric characteristics, maternal and neonatal outcomes in women that delivered by vaginal delivery with those who delivered by cesarean delivery. Overall, 769 deliveries were included. Of these, 98 women (12.7%) had cesarean delivery and 671 (87.3%) had vaginal delivery. Women who had cesarean delivery had a higher rate of obesity (44.9% vs 21.9%, p

OBJECTIVE Our primary objective was to compare maternal and neonatal outcomes based on the attempted mode of extraction. Our secondary objective was to compare the outcomes based on the actual mode of extraction. DESIGN A retrospective cohort study at a single tertiary centre between the years 2011 and 2019. SETTING The study included 1028 cases of term pregnancies in vertex presentation that were delivered by caesarean section at the second stage of delivery. POPULATION Patients were grouped according to the attempted mode of extraction: attempted cephalic extraction (674) and breech extraction (354). A subgroup analysis was conducted, comparing successful cephalic extraction (615), failed cephalic extraction (59) and breech extraction (354). METHODS Both maternal and neonatal complication rates were compared between the groups. RESULTS There were significantly more uterine incision extensions (27.4 versus 11.9%, P

Abnormal fetal tongue size is a phenotypic feature of various syndromes including Beckwith-Wiedemann, Pierre-Robin, oromandibular limb hypoplasia, chromosomal aberrations, etc. Current data regarding normal fetal tongue size are limited. Hence, micro/macroglossia are subjectively determined. The aim of the study was to construct a contemporary fetal tongue nomogram and to assess its clinical contribution.A prospective cross-sectional study was performed in well dated, low risk, singleton pregnancies. Fetal tongues were measured by 5 trained sonographers. Highest quality images were selected. Intra- and interobserver variability was assessed. Tongue length, width, area, and circumference 1st to 99th centiles were calculated for each gestational week. Based on the normal tongue size charts, we created a Tongue Centile Calculator.Over 18 months, 664 tongue measurements were performed. A cubic polynomial regression model best described the correlation between tongue size and gestational age. The correlation coefficient (rWe present novel fetal tongue size charts from 13 to 40 weeks of gestation. Clinical application of these nomograms may be beneficial in the prenatal diagnosis of syndromes or malformations associated with abnormal fetal tongue size.

To determine maternal and neonatal outcomes among women undergoing second stage emergent cesarean delivery (ECD) versus vacuum-assisted delivery (VAD) of low birthweight neonates.A retrospective cohort study from two tertiary medical centers. We included women who underwent either ECD or VAD during the second stage of labor, and delivered neonates with a birthweight of2500 g during 2011-2019. Characteristics and outcomes were compared between the groups. The primary outcome was the rate of a composite adverse neonatal outcome, defined as the presence of ≥1 of the following: Apgar 5 min 7, respiratory distress syndrome, neonatal intensive care unit admission, mechanical ventilation and intrapartum fetal death.The study cohort included 611 patients, of whom 46 had ECD and 565 had VAD. Baseline characteristics did not differ between the groups. The rate of Apgar score 7 at 1 min was higher among the ECD group]10 (22%) vs. 29 (5%), OR (95% CI) 5.1 (2.3-11.3), p 0.001[. Other neonatal and maternal outcomes were similar in both groups.Neonatal and maternal outcomes do not differ substantially between ECD and VAD of neonates weighing2500 g. This information may be useful when contemplating the preferred mode of delivery in this setting.

OBJECTIVE To evaluate the association between neonatal weight centile and neonatal and maternal morbidity following vacuum-assisted delivery (VAD) among term nulliparous women. METHODS A retrospective cohort study of all nulliparous women who delivered at term by VAD between 2011 and 2019. Deliveries were allocated into two groups and compared: (1) delivery of an small-for-gestational-age (SGA) neonate, and (2) delivery of an appropriate-for-gestational-age (AGA) neonate. RESULTS Overall, 3116 women were included in the study; 2878 (92.4%) were AGA and 163 (5.2%) were SGA and comprised the study groups. Neonatal and maternal adverse outcomes did not vary between groups. Rates of composite neonatal adverse outcome for SGA and AGA neonates were 26 (16.0%) versus 462 (16.1%), respectively (P = 0.972). Duration of the second stage of labor and rate of prolonged second stage were significantly lower among the SGA group compared with the AGA group (P

Background It has been suggested that women admitted for delivery should have universal PCR testing for SARS‐CoV‐2. Yet, the considerable difference in the incidence of COVID‐19 between different geographic regions may affect screening strategies. Therefore, we aimed to compare questionnaire‐based testing versus universal PCR testing for SARS‐CoV‐2 in women admitted for delivery. Methods A prospective cohort study of women admitted for delivery at a single center during a four‐week period (April 22‐May 25, 2020). All women completed a questionnaire about COVID‐19 signs, symptoms, or risk factors, and a nasopharyngeal swab for PCR for SARS‐CoV‐2. Women who were flagged as suspected COVID‐19 by the questionnaire (questionnaire‐positive) were compared with women who were not flagged by the questionnaire (questionnaire‐negative). Results Overall, 446 women were eligible for analysis, of which 54 (12.1%) were questionnaire‐positive. PCR swab detected SARS‐CoV‐2 in four (0.9%) women: 3 of 392 (0.8%) in the questionnaire‐negative group, and 1 of 54 (1.9%) in the questionnaire‐positive group (P = .43), yielding a number needed to screen of 92 (95% CI 62‐177). In 96% of the cases, the PCR results were obtained only in the postpartum period. No positive PCR results were obtained from neonatal testing for SARS‐CoV‐2. The sensitivity of the questionnaire was 75.0%, and the negative predictive value was 99.7%. Conclusions Although the rate of positive PCR results was not significantly different between the groups, the number needed to screen is considerably high. The use of questionnaire‐based PCR testing in areas with low incidence of COVID‐19 allows for a reasonable allocation of resources and is easy to implement.

Introduction We aimed to underline the determinants of adverse neonatal outcome in gestations complicated by placenta previa (PP). Methods A retrospective study including all women diagnosed with placenta previa carrying a singleton gestation who delivered between 2011 and June 2019. Gestations with adverse neonatal outcomes were compared to those without. In a secondary analysis, we further studied the rate of Placenta accreta spectrum (PAS) in relation to number of previous cesarean deliveries. Results Overall, 548/84,558 (0.6%) singleton deliveries were complicated by PP (0.6%). PAS was noted in 105 (19.2%) cases. After exclusion of PAS cases, adverse neonatal outcome occurred in 149/443 (33.6%), median gestational age of delivery was 37 0/7 with a median birthweight of 2780 g. In a univariate analysis, adverse neonatal outcome was associated with emergent delivery and general anesthesia [56.8% vs. 20.8%, OR 5.00 (95% CI) 3.24–7.72, p Discussion Efforts should be made to avoid general anesthesia in deliveries of PP.

Transition of clear amniotic fluid to meconium-stained fluid is a relatively common occurrence during labor. However, data regarding the clinical significance and the prognostic value of the presence of meconium-stained amnionic fluid (MSAF) are scarce. This study aimed to investigate delivery and neonatal outcomes according to the presence of MSAF and the timing of the meconium passage.We used an historical cohort study at a single tertiary medical center in Israel between the years 2011 and 2018. Women were divided into two groups according to timing of meconium passage: primary MSAF (MSAF present at membrane rupture) and secondary MSAF (clear amnionic fluid that transitioned to MSAF during labor). Neonatal complication rates were compared between groups. Composite adverse neonatal outcome was defined as arterial cord blood pHlt;7.1, 5 min Apgar score ≤7, and/or neonatal intensive care unit admission.The study cohort included 56 863 singleton term births. Of these, 9043 (15.9%) were to women who had primary MSAF, and 1484 (2.6%) to those with secondary MSAF. Secondary MSAF compared with primary MSAF increased the risks of cesarean birth and operative vaginal delivery, increased the risks of low one- and five-minute Apgar scores and low arterial cord blood pH, and increased hospital stay duration. Multivariate analysis revealed that secondary MSAF was independently associated with an increased risk of composite adverse neonatal outcome (OR1.68, 95% CI 1.25-2.24, p lt; 0.001) compared with primary MSAF.In this sample, secondary MSAF was associated with more adverse neonatal outcomes than primary MSAF. Closer monitoring of fetal well-being may be prudent in these cases.

The risk of cesarean delivery after a successful external cephalic version for breech presentation is higher as compared with fetuses in cephalic presentation. However, the role of the time interval between version attempt to delivery on the risk for cesarean delivery is unclear. We aimed to study the effect of the time interval from a successful external cephalic version to delivery on the risk for cesarean delivery and assess factors associated with cesarean delivery after a successful version.We conducted a multicenter, retrospective cohort study, including all successful external cephalic version at two medical centers between 2011 and 2019. We compared patient baseline characteristics, obstetric characteristics, maternal and neonatal outcomes in women that delivered by vaginal delivery with those who delivered by cesarean delivery.Overall, 769 deliveries were included. Of these, 98 women (12.7%) had cesarean delivery and 671 (87.3%) had vaginal delivery. Women who had cesarean delivery had a higher rate of obesity (44.9% vs 21.9%, p 0.001; OR 2.88, CI 1.65-5.03) and nulliparity (45.9% vs 24.5%, p 0.001; OR = 2.58, CI 1.67-3.98). The risk for intrapartum cesarean delivery did not differ according to time interval from external cephalic version to delivery.The time interval between successful external cephalic version and delivery was not associated with mode of delivery. This finding is in contrast to previous reports. The risk for cesarean delivery after successful version is higher in nulliparous, obese women, and women whose weight gain in pregnancy was higher.

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.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.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) and4,000 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),Among pregestational diabetic women, the accuracy of sonographic EFW when assessed to be3,500 grams is questionable. This should be taken into consideration when consulting women and planning delivery management.Among pregestational diabetic women, the accuracy of estimated sonographic fetal weight higher than 3,500 grams is of limited accuracy.

Intraamniotic infection, categorized into isolated maternal fever, suspected intraamniotic infection (SII), and confirmed intraamniotic infection, is associated with neonatal morbidity. However, there is paucity of data regarding the association between intraamniotic infection duration and neonatal outcomes among term singleton vaginal deliveries. We aimed to study the risk factors for adverse neonatal outcome among vaginal deliveries complicated by SII. A retrospective observational study conducted at a tertiary medical center. All consecutive singleton term deliveries with SII were included between 2011 and 2019. Maternal and obstetrical characteristics were evaluated to identify risk factors for adverse neonatal outcome. Correlation between SII duration and neonatal adverse outcome was analyzed. Overall, 882 were analyzed. Most women (85.4%) were primiparous. Median gestation age at delivery was 40 2/7 weeks. Median time from SII to delivery was 170 min. Adverse neonatal outcomes occurred in 113 (12.8%) of deliveries. Duration of SII was not associated with adverse neonatal outcome. Analysis for determinants of adverse neonatal outcome revealed that oligohydramnios was more common in pregnancies with adverse neonatal outcome (7/113 (6.2%) vs. 41 (5.4%) OR [95% CI] 2.47 (1.02–5.98), p = 0.03). Duration of second stage of labor was longer in the adverse outcome group (median 179 min vs. 126 min, p = 0.008). Prolonged second stage was more common in the adverse outcome group (60 (53.1%) vs. 273 (35.5%) OR [95% CI] 2.05 (1.38–3.06), p

Nulliparity and operative vaginal delivery are established risk factor for obstetric anal sphincter injury (OASI). However, risk factors for OASIS occurrence among parous women delivering vaginally are not well-established. We aimed to study the risk factors for OASI occurrence among parous women. A retrospective study including all parous women who delivered vaginally at term during 2011–2019 at a university hospital. Deliveries of parous women with OASI were compared to deliveries without OASI. The risk factors associated with OASI were investigated. Overall, 35,397 women were included in the study with an OASI rate of 0.4% (n = 144). A higher rate of only one previous vaginal delivery was noted in the OASI group (78.5% vs. 46.4%, OR [95% CI] 4.20, 2.82–6.25, p

Most professional guidelines advise against routine episiotomy during vaginal delivery, although mounting evidence supports its protective role regarding obstetric anal sphincter injury (OASI). We aimed to study the effect of lateral and mediolateral episiotomies on the rate of OASI in relation to birthweight among nulliparous women undergoing vaginal delivery.A historical cohort study was conducted of all nulliparous women who delivered vaginally at term between 2011 and 2019 at a tertiary university hospital. Women were allocated into two groups: (1) with OASI and (2) without OASI. Episiotomy performance and birthweight groups were analyzed.Overall, 22,250 deliveries were analyzed for inclusion: 18,533 (83.3%) spontaneous vaginal deliveries (SVD), 3222 (14.5%) vacuum-assisted deliveries (VAD) and 495 (2.2%) forceps deliveries. Total episiotomy and OASI rate was 48.2% and 1.7%, respectively. Episiotomy rate was lower in the OASI group as compared to the no OASI group (158 (41.3%) vs. 10,568 (48.3%), OR 0.75, 0.61-0.92, p = 0.006). Median birthweight was higher for OASI group neonates (3355 vs. 3160, p 0.001). In SVDs, episiotomy decreased the rate of OASI in neonatal birthweight groups of 3000-3499, 3500-3999 and 4000 g (OR 0.56, 0.38-0.82, p = 0.003; 0.66, 0.45-0.99, p = 0.04 and 0.24, 0.07-0.78, p = 0.01, respectively). In VADs, episiotomy decreased the rate of OASI in the neonatal weight groups of 2500-2999 and 3000-3499 g (OR 0.36, 0.14-0.89, p = 0.02 and OR 0.38, 0.19-0.75, p = 0.004, respectively).Lateral and mediolateral episiotomies are independent modifiable predictors of OASI, protective against OASI in SVDs when neonates weigh 3000 g and 2500-3499 g in VADs.

Patients with Marfan syndrome (MS) face a high risk of aortic dissection during pregnancy. A dilated aortic root (>40 to 45 mm) is considered a relative contraindication for pregnancy. We investigated the risk for aortic dissection and pregnancy outcome in patients with MS. Women with MS who attended our cardiology high-risk pregnancy clinic from 2006 to 2015 were followed clinically and with serial echocardiograms by a multidisciplinary team. Beta blockers were offered and titrated by blood pressure and heart rate. Patients with aortic root dilation ≥40 mm were considered high-risk patients with MS. A consistent increase in aortic root diameter of >1 mm during pregnancy was classified as dilation during pregnancy; 31 pregnancies in 19 patients with MS were followed. Four pregnancies were terminated early because of prenatal diagnosis of fetal MS and 4 additional babies born with MS. Eight pregnancies were in patients with a dilated aortic root (40 to 46 mm); 21 patients (68%) were treated with β blockers. There were 2 cases of postpartum aortic dissection (6.5%): 1 type A dissection in a woman with a dilated aortic root who declined β blockers (1 of 8, 12.5%) and 1 type B dissection. Increasing aortic root diameter (>1 mm) in pregnancy was significantly associated with later aortic dissection (2 of 6 vs 0 of 21, p = 0.04). No maternal deaths occurred. All high-risk women with MS gave birth by cesarean section, whereas in the non–high-risk group mode of delivery was by obstetric indication. Preterm delivery rate was 41% (11 of 27). One antenatal fetal death and no major neonatal morbidity or mortality were observed. In conclusion, pregnant patients with MS, especially those with a dilating aortic root, are at high risk of aortic dissection, even with tight control of blood pressure and heart rate.

Objective Bed rest or activity restriction is a common obstetrical practice, despite a paucity of data to support its efficacy. The aim of this study was to determine whether physical activity, as assessed by a smart band activity tracker, is associated with preterm birth in pregnant women at high risk for preterm delivery. Methods This was a pilot prospective cohort study including pregnant women at high risk for preterm delivery between 24 and 32 weeks-of-gestation. Physical activity level was assessed by smart band activity. Patients with sonographic short cervical length (≤ 20 mm) were asked to wear the smart band activity tracker continuously for at least one week, including one weekend. Both physicians and patients were blinded to the data stored in the smart band activity tracker. No specific recommendations were given to participants as to the level or intensity of physical activity. The primary outcome was the rate of preterm birth (< 37 weeks-of-gestation). Secondary outcomes included the rate of delivery before 34 weeks of gestation and neonatal outcome. Parametric and nonparametric statistics were used for analysis. Results Study population included 49 pregnant women: 37 women (75.7%) delivered preterm and 12 (24.5%) delivered at or after 37 weeks-of-gestation. The median steps per day was significantly lower in patients who delivered preterm (3576, IQR: 2478–4775 vs. 4554, IQR: 3632–6337, p = 0.02). Regression analysis revealed that the median number of steps per day was independently inversely associated with preterm birth, after adjustment for maternal age, body mass index, gestational age at recruitment, cervical length, cervical dilatation and plurality. Conclusion This pilot study represents the first quantitative assessment of the association between physical activity and preterm birth. The results of this pilot study do not support the efficacy of decreased physical activity in the prevention of preterm birth in patients with sonographic short cervical length.

Objective To evaluate adequacy and adherence to American Society for Reproductive Medicine (ASRM) guidelines of internet information provided by Society for Assisted Reproductive Technology (SART)-affiliated clinics regarding social oocyte cryopreservation (SOC). Design Systematic evaluation of websites of all SART member fertility clinics. Setting The internet. Patient(s) None. Intervention(s) All websites offering SOC services were scored using a 0–13 scale, based on 10 questions designed to assess website quality and adherence to the ASRM/SART guidelines. The websites were analyzed independently by two authors. Whenever disagreement occurred, a third investigator determined the score. Main Outcome Measure(s) Scores defined website quality as excellent, ≥9; moderate, 5–8; or poor, ≤4 points. Result(s) Of the 387 clinics registered as SART members, 200 offered oocyte cryopreservation services for either medical or social reasons; 147 of these advertised SOC. The average website scores of those clinics offering SOC was 3.4 ± 2.1 (range, 2–11) points. There was no significant difference in scores between private versus academic clinics or clinics performing more or less than 500 cycles per year. Conclusion(s) The majority of the websites do not follow the SART/ASRM guidelines for SOC, indicating that there is a need to improve the type and quality of information provided on SOC by SART member websites.
