RESUMO
BACKGROUND: We aimed to assess the association between isolated oligohydramnios in previous pregnancy and the incidence of placental related complications in subsequent pregnancy. METHODS: This was a retrospective cohort study of live singleton births from a single university affiliated medical center during an eleven-year period of women with two subsequent deliveries at our center. An analysis of outcomes was performed for all second deliveries, comparing women for whom their first delivery was complicated by isolated oligohydramnios (previous oligohydramnios group), and women without isolated oligohydramnios in their first delivery (control group). Patients for whom their first delivery was complicated by small for gestational age, pregnancy induced hypertension and preterm birth were excluded. The study groups were compared for obstetric and early neonatal outcomes, recurrence of oligohydramnios and a composite of placental related pregnancy complications. RESULTS: A total of 213 in the previous oligohydramnios group and 5348 in the control group were compared. No differences were found between the groups in maternal age, body mass index, smoking and comorbidities. Gestational age at delivery was, 39.6 ± 1.3 vs. 39.3 ± 1.4 weeks, p = 0.006, in the previous oligohydramnios and controls respectively, although preterm birth rate was similar between the groups. The previous oligohydramnios group had a significantly higher incidence of oligohydramnios in second delivery, aOR 3.37, 95%CI 1.89-6.00, small for gestational age neonates, aOR 1.94, 95% CI 1.16-3.25, and overall placental related disorders of pregnancy, aOR 2.13, 95%CI 1.35-3.35. CONCLUSION: Pregnancies complicated by isolated oligohydramnios are associated with an increased risk of placental related disorders in subsequent pregnancy. Isolated oligohydramnios may be the first sign of placental insufficiency and an independent manifestation of the placental related complications spectrum.

This retrospective cohort study evaluated pregnancy outcomes and similarities between pairs of nulliparous sisters with a singleton fetus who delivered between 2013 and 2020. The "Sister-1 group" was defined as the sibling who delivered first, while the "Sister-2 group" included the siblings who gave birth after Sister-1. Obstetrical complications and delivery outcomes were compared. The relative risk for recurrence of a complication in Sister-2 was calculated. The study included 743 sister pairs. There were no between-group differences in maternal BMI, gestational age at delivery, gravidity, smoking, or epidural rates. The Sister-2 group was older than the Sister-1 group (26.4 ± 5 vs. 25.8 ± 4.7 years, respectively, p = 0.05). Higher birthweights and more large-for-gestational-age infants characterized the Sister-2 group compared with the Sister-1 group (3241 ± 485 g vs. 3148 ± 536 g, p < 0.001 and 7.7% vs. 4.8%, p = 0.025, respectively). There were no between-group differences in the rate of small-for-gestational-age, gestational diabetes, hypertensive disorders, pre-term births, vacuum extraction, or cesarean deliveries. Logistic regression analysis found that if Sister-1 underwent vacuum extraction, her sibling had an increased risk for vacuum delivery (adjusted RR 3.03, 95% CI 1.4−6.7; p = 0.003) compared with those whose sibling (Sister-1) did not. There was a three-fold risk of vacuum extraction delivery between sisters. This finding could be related to biological inheritance, environmental factors, and/or psychological issues that may affect similarities between siblings' delivery outcomes.
RESUMO
Clinical estimation of fetal weight is an integral component of obstetric care that might dictate the timing and mode of delivery. Inaccurate fetal weight estimation might result in unnecessary interventions or in underestimating potential risks, resulting in inappropriate intrapartum care. This retrospective study assessed factors associated with under- or overestimation of birthweight and evaluated the obstetric implications. It included singleton births ≥24 w with clinically estimated fetal weight (EFW) up to 1 week before delivery, during 2014−2020. Estimates >±10% of the actual birthweight were considered inaccurate and categorized as overestimation (>10% heavier than the actual birthweight) or underestimation (>10% smaller than the birthweight). Multivariable logistic regression was performed to reveal factors associated with inaccurate EFW. Maternal characteristics and obstetric outcomes were compared. The primary outcomes for the overestimation group were the neonatal composite adverse outcome, induction of labor and cesarean delivery rates. The primary outcomes for the underestimation group were rates of shoulder dystocia, 3rd- or 4th-degree perineal lacerations, and failed vacuum extraction. Among 38,615 EFW, 5172 (13.4%) were underestimated, 6695 (17.3%) were overestimated and 27,648 (69.3%) accurate. Multivariable logistic regression found increasing gestational age as an independent risk-factor for underestimation (odds ratio (OR) 1.15 for every additional week, 95% confidence interval (CI) 1.12−1.2). Major factors independently associated with overestimation were nulliparity (OR 1.95, CI 1.76−2.16), maternal obesity (OR 1.52, CI 1.33−1.74), smoking (OR 1.6, CI 1.33−1.93), and oligohydramnios (OR 1.92, CI 1.47−2.5). Underestimation was an independent risk-factor for shoulder dystocia (OR 1.61, CI 1.05−2.46) and 3rd- or 4th-degree perineal lacerations (OR 1.59, CI 1.05−2.43). Overestimation was an independent risk-factor for neonatal composite adverse outcome (OR 1.15, CI 1.02−1.3), induced labor (OR 1.30, CI 1.21−1.40) and cesarean delivery (OR 1.59, CI 1.41−1.79). Clinicians should be aware of factors and adverse obstetric implications associated with over- or underestimation of birthweight.
RESUMO
BACKGROUND: We aimed to assess the correlation between ovarian hyperstimulation syndrome (OHSS) in the early course of in vitro fertilization (IVF) pregnancies and obstetric outcomes. METHODS: We identified records of patients admitted due to OHSS following IVF treatment at our institution between 2008 and 2020. Cases were included if pregnancy resulted in a live singleton delivery (OHSS group). OHSS cases were matched at a 1:5:5 ratio with live singleton deliveries following IVF with fresh embryo transfer (fresh transfer group) and frozen embryo transfer (FET group), according to maternal age and parity. Computerized files were reviewed, and maternal, obstetric and neonatal outcomes compared. RESULTS: Overall, 44 OHSS cases were matched with 220 fresh transfer and 220 FET pregnancies. Patient demographics were similar between the groups, including body mass index, smoking and comorbidities. Gestational age at delivery, the rate of preterm births, preeclampsia and cesarean delivery were similar between the groups. Placental abruption occurred in 6.8% of OHSS pregnancies, 1.4% of fresh transfer pregnancies and 0.9% of FET pregnancies (p=0.02). On post-hoc analysis, the rate of placental abruption was significantly higher in OHSS pregnancies, compared with the two other groups, and this maintained significance after adjustment for confounders. Birthweights were 3017 ± 483, 3057 ± 545 and 3213 ± 542 grams in the OHSS, fresh transfer and FET groups, respectively (p=0.004), although the rate of small for gestational age neonates was similar between the groups. CONCLUSIONS: OHSS in the early course of IVF pregnancies is associated with an increased risk of placental abruption.

BACKGROUND: Antenatal detection of abdominal circumference (AC) <10th percentile, among small for gestational age (SGA) neonates, probably reflects the severity of their growth restriction. We aimed to study neonatal outcome and placental pathology among SGA neonates in correlation to their AC measurements. METHODS: Maternal and neonatal computerized medical records and placental histopathology reports of all SGA neonates, (neonatal birth-weight ≤10th percentile), born between 24 and 42 weeks, during 2015-2018 were reviewed. Included cases with fetal biometric measurements conducted up to 7 days prior labor. Results were compared between cases with sonographic antenatal AC <10th percentile and neonates with sonographic antenatal AC ≥10th percentile. Placental lesions were classified according to "Amsterdam" Placental workshop criteria. RESULTS: The AC <10th percentile group (n = 148) was characterized by higher rate of nulliparity (p = .003), and induction of labor (p = .009), as compared to the AC ≥10th percentile group (n = 41). There were no between groups differences in the rate of maternal BMI (kg/m2), hypertensive disorders, diabetes or smoking. Neonatal hypoglycemia was more common in the AC <10th percentile group as compared to the AC ≥10th percentile group (p = .04). Placentas from the AC <10th percentile group were smaller (p < .001), with more MVM lesions (p = .02) and chronic villitis (p = .04). By multivariate regression analysis, AC <10th percentile and maternal hypertensive disorders, were found to be independently associated with placental MVM lesions, aOR = 2.43 (95% CI 1.04, 5.88) and aOR = 3.15 (95% CI 1.06, 9.31), respectively. CONCLUSIONS: Higher rate of placental maternal malperfusion lesions, chronic villitis, and more neonatal hypoglycemia characterize SGA neonates with AC <10th percentile, pointing to the importance of AC measurement as an indicator for placental insufficiency.

INTRODUCTION: We aimed to investigate the effect of maternal passive smoking (MPS) during pregnancy-on placental pathology and pregnancy outcomes. METHODS: A prospective case-control study. We recruited low-risk laboring women at 37+0-41 + 0 weeks between 9/2019-7/2020. MPS was defined as exposure to in-house spouse tobacco smoking of >20 cigarettes/day in the absence of maternal active-smoking. In attempt to "purify" the effect of MPS on placental pathology-we excluded cases with preeclampsia, diabetes, suspected fetal growth restriction (FGR), preterm labor, and illicit drug use. Maternal characteristics, pregnancy outcomes, and placental pathology were compared between the MPS group and a control group matched for gestational age, maternal age, and delivery date. Placental lesions were classified according to the "Amsterdam" criteria. The study was powered to detect a 33% difference in placental malperfusion lesions. Multivariable regression was performed to identify independent associations with placental malperfusion lesions. RESULTS: In labor, the MPS group (n = 115) had higher rates of meconium stained amniotic fluid (MSAF, p < 0.001) and non-reassuring fetal heart-rate (NRFHR,p = 0.006), compared to controls (n = 115). Neonates in the MPS group had higher rates of undiagnosed FGR (p = 0.01) and NICU admissions (p = 0.004). The MPS group had higher rates of placental-hypoplasia (p = 0.02) and fetal vascular malperfusion (FVM) lesions (p = 0.04). In regression analysis MPS was associated with FVM lesions independent of background confounders (aOR = 1.24 95% CI 1.10-2.65). DISCUSSION: In otherwise low-risk pregnancies, MPS was associated with higher rates of MSAF, NRFHR, undiagnosed FGR, and NICU admissions, probably mediated via placental FVM. These worrisome findings mandate patient counseling and further investigation in larger population-based studies.

INTRODUCTION: Preterm labor is defined as delivery before 37 weeks of gestation. Up to 17% of twin pregnancy are preterm. Arabin cervical pessary has been proven as preventing preterm labor in singleton pregnancies. The benefit of it in twin pregnancy is controversial. OBJECTIVES: The purpose of this study was to compare the rate of preterm delivery in twin gestation with short cervical length in Israel- one center utilized the combined treatment of Arabin cervical pessary and vaginal progesterone (study group) and the others utilized vaginal progesterone approach (control group). METHODS: Multi-center retrospective cohort study, including "Shamir", "Wolfson", "Shaare Zedek" and "Galilee" medical centers, between the years 2012-2016. Inclusion criteria were twin gestations and short cervical length (<25mm) between 16-28 weeks' gestation. RESULTS: The study group included 68 women, the control group 78 women. The study group had shorter cervical length at intervention in comparison to the control group (13.6 ± 5.9 vs. 16.5 ± 5.7, respectively, p = .002). The treatment started later for the study group compared to the control group (23.2 +2.2 vs 22.6 +3.0). CONCLUSIONS: Despite having shorter cervical length at recruitment, the rate of spontaneous delivery < 34-weeks' gestation was similar in both groups (36.8 vs. 37.2%, respectively). DISCUSSION: Considering the conclusion in this research it seems that the combination of the mechanical effect of the pessary by embracing the cervix, keeping the cervical mucus, bending it in a way that the pressure is towards the anterior cervical wall together with the progestative effect which increases the estrogen/progesterone ratio, creating uterine quiescence and keeping the structural connective tissue of the cervix have an added benefit. It seems that the combined use of Arabin cervical pessary and vaginal progesterone in twin pregnancy with short cervical length have a synergic effect which may have a benefit in preventing preterm labor. The combination of cervical pessary and progesterone does not negatively affect twin pregnancy outcome and does not cause preterm birth.

PURPOSE: Preterm birth is the leading cause of perinatal morbidity and mortality. Vaginal progesterone cervical cerclage and Arabin cervical pessary are considered as preventive treatments in women at risk for preterm birth. However, there is less evidence as to which of these interventions is the preferred management. The current study aims was to compare the outcome of pregnancy in women with a short cervical length managed with 4 different treatment protocols: therapy with vaginal progesterone, cervical cerclage and an Arabin cervical pessary (group A), Arabin cervical pessary and vaginal progesterone (group B), cervical cerclage and vaginal progesterone (group C), or vaginal progesterone alone (group D). METHODS: A retrospective cohort study of singleton pregnancies managed in three tertiary medical centers between September 2011 and December 2017. RESULTS: In the study period, 286 pregnant women underwent vaginal ultrasonography between 15 and 29 weeks gestation. They all had a short cervical length (≤25 mm). Of these, 18 (6.3%), 120 (41.9%), 38 (13.3%) and 110 (38.5%) patients received treatment classifying them into groups A, B, C, and D, respectively. A significantly higher rate of patients in group A had either a history of cervical incompetence (44.4 versus 9.2 versus 7.9 and 0.9%, respectively, p = .0001) or a cervical procedure (61.1 versus 37.5 versus 28.9 and 27.3%, respectively, p = .027) compared to patients in group B, C, and D. Despite having a shorter cervical length at recruitment in group A (median (range); 14.5 (0-25) versus 15 (0-25) versus 15.5 (0-25) and 19 (2-25) mm, respectively, p = .002) the rate of spontaneous preterm delivery <37-week gestation was similar across groups (44.4 versus 32.5 versus 36.8 versus 32.7%, respectively, p = .665). CONCLUSION: A combined rescue therapy involving vaginal progesterone, cervical cerclage, and Arabin cervical pessary emerges as a promising management strategy in pregnant women who have a short cervical length and a high background risk for preterm delivery. This combination may prolong their pregnancy and safely bring them near term. Additional studies are needed to confirm these preliminary findings.

We compared placental pathology, ultrasonographic findings, and obstetric outcomes, in gestations complicated by fetal growth restriction (FGR) with either a background of hypertensive disorder or heavy tobacco cigarette smoking. The medical records and placental pathology reports of pregnancies complicated with FGR (birthweight < 10th percentile) between December 2008 and May 2018 from a single tertiary center were reviewed. Placental pathology, ultrasound findings, and pregnancy outcomes were compared between hypertensive patients (HTN) and heavy smokers (SMO). We included 213 pregnancies: 129 (60.6%) in the SMO group and 84 (39.4%) in the HTN group. The HTN group was characterized by a higher BMI (p = 0.01), higher rates of Cesarean deliveries (p = 0.006), and a lower gestational age at delivery (35.6 ± 3.8 vs. 37.5 ± 2.9 weeks, p < 0.001). The HTN group had higher rates of placental weights < 10th percentile (p = 0.04) and maternal vascular malperfusion lesions (p < 0.001), while the SMO group had higher rates of inflammatory lesions (p = 0.04). On ultrasound, the HTN group had a higher head/abdomen circumference ratio (p < 0.001) and more abnormal Doppler studies (< 0.001). Neonates in the HTN group had lower birthweights (p < 0.001) and higher rates of NICU admissions (p = 0.002) and adverse neonatal outcome (p = 0.006). On multivariable analysis, gestational age at delivery (aOR = 0.65, 95%CI 0.55-0.87), hypertensive disorders (aOR = 1.8, 95%CI = 1.21-4.81), placental MVM lesions (aOR = 1.23, 95%CI = 1.08-5.02), and the combination of HTN+MVM (aOR = 2.63, 95%CI 1.78-7.30) were independently associated with adverse neonatal outcome. Hypertension and smoking may lead to FGR in different pathways as the two groups significantly differed in maternal characteristics, placental pathology, ultrasound findings, and neonatal outcomes. A hypertensive disorder probably represents a more hostile maternal environment than smoking and these pregnancies would probably benefit from closes monitoring.

INTRODUCTION: We aimed to study the correlation between the extent of placental abruption (PA), as grossly estimated immediately after delivery, and pregnancy outcomes, in correlation with placental histopathology. MATERIALS AND METHODS: Pregnancy and placental reports of all pregnancies complicated by PA (clinically diagnosed) between 11/2008-12/2018 were reviewed. We compared maternal background, pregnancy outcomes, and placental histopathology between cases of PA divided into three groups according to the extent of abruption: Group 1-<30 %, Group 2-30-49 %, and Group 3->50 % of placental surface. Placental lesions were classified according to the current "Amsterdam" criteria. The primary outcome was defined as a composite of severe neonatal morbidity and included ≥ 1 of the following complications: seizures, intraventricular hemorrhage, hypoxic-ischemic encephalopathy, periventricular leukomalacia, blood transfusion, necrotizing enterocolitis, intrauterine fetal demise, or neonatal death. RESULTS: A total of 260 PA cases were included: 111 (42.7 %) in Group 1, 94 (36.2 %) in Group 2, and 55 (21.1 %) in Group 3. The rate of the primary outcome (7.2 % vs. 11.7 % vs. 27.3 %, p = 0.02) was associated with the degree of PA as well as maternal heavy smoking (p = 0.04), DIC (p = 0.03), umbilical artery Ph <7.1 (p = 0.02), 5-minute Apgar scores <7 (p = 0.03), NICU admissions, placental maternal vascular malperfusion lesions (p = 0.04), and neonatal weights <5th percentile (0.04). In multivariable analysis severe adverse neonatal outcome was independently associated with the percentage of PA (aOR = 1.4, 95 % CI = 1.3-3.9). CONCLUSION: The extent of placental abruption, as estimated by the examiner, correlated with DIC and severe neonatal outcomes and may serve as an early alarming sign in deliveries complicated by PA.

BACKGROUND: The incidence of thromboembolic complications is highest in the immediate postpartum period, especially following caesarean delivery (CD). Ambulation following CD is important in their prevention. We examined the effect of an educational protocol on patients' mobility following CD, with the use of digital step counters (pedometers). METHODS: Starting February 2018, we implemented an educational protocol at the maternity ward, which included nurses' tutoring and subsequent patients' education, regarding the importance of early ambulation. Following CD, ambulation was initiated 4 h following surgery (as compared to 6 h prior). Scheduled IV acetaminophen was administered at six-hour intervals for 48 h (as compared to only 24 h prior), while additional analgesics were given upon patient request. We compared maternal demographics, delivery and postpartum course between the pre-protocol group (n = 101) and the post-protocol group (n = 100). All patients were asked to wear pedometers for 48 h following the delivery to assess ambulation. RESULTS: Patients' demographics, surgical and post-partum course were non-significant between the groups, except for surgical length (48.5 ± 14.6 vs. 53.5 ± 15.3 min in the pre and post protocol groups, respectively, p = 0.02). The pre-protocol group was treated with more additional analgesics (p = 0.02). A higher number of steps was taken in the post-protocol group as compared to the pre-protocol group (4394 ± 2985 vs.3551 ± 2931, respectively p = 0.04). In a linear regression analysis in which the number of steps served as the dependent variable, this educational protocol was independently associated with a higher number of steps [coefficient 988 steps, 95% CI 137-1838, p = 0.02], as was smoking, after adjustment for surgical length, emergent surgery, maternal age and body mass index. CONCLUSION: An educational protocol which included earlier ambulation and regular interval pain control was associated with improved ambulation following CD.

OBJECTIVE: To assess the effect of a personalized repeated feedback approach using digital step counters (pedometers) on mobility after cesarean delivery in high-risk patients. METHODS: This was a randomized controlled trial at a tertiary university hospital. Patients who underwent cesarean delivery and were defined as high risk for thromboembolic events were asked to wear a pedometer around their wrists postpartum for 48 hours. Patients were randomized to the feedback group, which received personalized feedback by the research staff regarding their mobility at three set timepoints, or the control group, which received standard care. The number of steps taken by patients was compared between the groups and served as the primary outcome. Secondary outcomes included patient reported pain, physical and mental recovery, and overall satisfaction. Sample size was predetermined to detect a 25% between-group difference in the primary outcome. RESULTS: From December 2018 to July 2019, 215 patients were recruited, randomized and completed follow-up-108 in the feedback group and 107 in the control group. Patients' demographics and intrapartum course were similar between the groups. The number of steps taken was significantly higher in the feedback group compared with the control group: 5,918±3,116 vs 4,161±2,532 steps, P<.001. Pain scores were similar between the groups, as was analgesic consumption. Patients in the feedback group reported a significantly easier physical and mental postpartum recovery and were significantly more satisfied with their delivery experience. Postpartum complications did not differ between the groups. CONCLUSION: In high-risk patients after cesarean delivery, mobility was improved by using a personalized feedback approach. Enhanced mobility was not associated with a higher rate of complications or pain and was positively associated with patient satisfaction. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov, NCT03724760.

INTRODUCTION: Adaptations to pathological intrauterine environment might differ in relation to fetal gender. We aimed to study sex-specific differences in placental pathology of pregnancies complicated by small for gestational age (SGA). METHODS: The medical records and placental histology reports of all neonates with a birth-weight ≤ 10th percentile, born between 24 and 42 weeks of gestation, during 2010-2018, were reviewed. Composite neonatal outcome was defined as one or more of early following complications: neonatal sepsis, blood transfusion, phototherapy, respiratory morbidity, cerebral morbidity, necrotizing enterocolitis, or death. Results were compared between the male and female groups of neonates. Placental lesions were classified into maternal and fetal vascular malperfusion (MVM and FVM) lesions, maternal and fetal inflammatory responses (MIR and FIR), and villitis of unknown etiology (VUE). RESULTS: The male SGA group (n = 380) and the female SGA group (n = 363) did not differ in regard to maternal age, BMI, smoking, associated pregnancy complications, gestational age, and mode of delivery. Neonates in the SGA male group had increased birth-weight and increased respiratory morbidity as compared to the female SGA group (p = 0.007, p = 0.005, respectively). There was no between-group differences in the rate of placental lesions. By multivariate logistic regression analysis, male gender (aOR 1.55, 95% CI 1.05-2.30, p = 0.025), FIR (aOR 4.83, 95% CI 1.07-13.66, p = 0.003), and VUE (aOR 1.89, 95% CI 1.03-3.47, p = 0.04), were found to be independently associated with adverse composite neonatal outcome. DISCUSSION: Male gender as well as placental FIR and VUE are independently associated with adverse neonatal outcome in SGA neonates.

OBJECTIVE: We aimed to assess the outcomes of low-risk pregnancies complicated by isolated reduced fetal movements (RFM) at term. STUDY DESIGN: The study population were patients at term, with singleton, low-risk, pregnancies who presented to our obstetric-triage and delivered during the subsequent 2 weeks. The study group included patients with an isolated complaint of RFM (RFM group). The control group included patients without history of RFM (control group). The pregnancy, delivery, and neonatal outcomes were compared between the groups. Severe and mild composites of adverse neonatal outcomes were defined. Multivariate regression analyses were performed to identify independent association with adverse neonatal outcomes. RESULTS: Among the 13,338 pregnant women, 2762 (20.7%) were included in the RFM group and 10,576 (79.3%) in the control group. The RFM group had higher rates of nulliparity (p < 0.001), and smoking (p < 0.001). At admission, the RFM group had higher rates of IUFD (p < 0.001). The RFM group had higher rates of Cesarean delivery due to non-reassuring fetal monitor (p < 0.001), and mild adverse neonatal outcomes (p = 0.001). RFM was associated with mild adverse outcome independent of background confounders (aOR = 1.4, 95% CI 1.2-2.6, p < 0.001). CONCLUSION: Patients presented with isolated RFM at term had higher rates of IUFD at presentation and significant adverse outcomes at delivery.

OBJECTIVE: We aimed to compare pregnancy outcomes in association with placental pathology in pregnancies complicated by macrosomia in diabetic vs. non-diabetic women. STUDY DESIGN: Pregnancies complicated by macrosomia (≥4000gr) were included. Pregnancy and delivery characteristics, neonatal outcomes and placental histopathology reports were compared between macrosomia in diabetic [pre-gestational or Gestational Diabetes Mellitus (GDM)] women (diabetic-macrosomia group) vs. non-diabetic women (non-diabetic macrosomia group). Adverse neonatal outcome was defined as ≥1 neonatal complications. Multivariate analysis was used to identify independent associations with adverse neonatal outcome. RESULTS: The diabetic macrosomia group (nâ¯=â¯160) was characterized by higher maternal age (pâ¯=â¯0.002), Body Mass Index (BMI) (pâ¯<â¯0.001), and smoking (pâ¯=â¯0.03), and lower gestational age at delivery (pâ¯=â¯0.001). The diabetic-macrosomia group had higher rates of scheduled Cesarean deliveries (CDs) (58.9 % vs23.7 %,pâ¯<â¯0.001) while the non-diabetic macrosomia group (nâ¯=â¯214) had higher rates of emergent CDs (76.3 % vs.40.7 %,pâ¯<â¯0.001), perineal tears (pâ¯=â¯0.027) and Post Partum Hemorrhage (PPH) (pâ¯=â¯0.006). Placentas from the non-diabetic macrosomia group were characterized by higher rates of maternal and fetal inflammatory response lesions (pâ¯<â¯0.001). Except for higher jaundice rate in the diabetic macrosomia group (pâ¯<â¯0.001), none of the other neonatal outcomes including shoulder dystocia differed between the groups. In multivariate analysis GAâ¯<â¯37 weeks (aORâ¯=â¯1.4,95 %,CI-1.2-3.9), and emergent CDs (aORâ¯=â¯1.7,95 %,CI-1.4-4.1) but not diabetes (aORâ¯=â¯1.1,95 %,CI-0.7-3.9) were associated with adverse neonatal outcome. CONCLUSIONS: Despite major differences in maternal demographics, mode of delivery, maternal morbidity, and placental characteristics- adverse neonatal outcome did not differ between macrosomia in diabetic vs. non-diabetic women and was high in both groups. Clinicians should be aware of the high rate of adverse neonatal outcome in macrosomic fetuses, even in the absence of diabetes mellitus.

OBJECTIVE: We investigated the association between prenatal selective serotonin reuptake inhibitors (SSRI) exposure and pregnancy-outcomes with correlation to placental-histopathology. STUDY DESIGN: Included were pregnancies with maternal SSRI use throughout pregnancy (SSRI-group) and the control group was matched with pregnancies unexposed to SSRI. Placental lesions were classified according to the "Amsterdam" criteria. Adverse neonatal outcome was defined as ≥1 early neonatal-complications. RESULTS: SSRI group had lower birthweights (p < 0.001), higher rates of meconium (p = 0.009), NICU admissions (p < 0.001), and adverse neonatal-outcome (p < 0.001). SSRI placentas had lower birthweight-to-placental-weight ratio (p = 0.02) and higher rates of fetal vascular malperfusion (FVM) lesions (p = 0.03). Using multivariable analyses: GA < 37 weeks (aOR = 2.1, 95%CI 1.7-4.6) and SSRI (aOR = 1.7, 95%CI 1.3-3.9) were independently associated with adverse neonatal outcome while GA < 37 weeks (aOR = 1.6, 95%CI 1.2-3.4), SSRI (aOR = 1.3, 95%CI 1.1-2.6), and smoking (aOR = 1.2, 95%CI 1.1-4.0) were independently associated with FVM lesions. CONCLUSION: SSRI use during pregnancy was independently associated with adverse neonatal outcome and placental FVM.

Purpose: To compare the rate of preterm delivery in pregnant women with a short cervical length managed with Arabin cervical pessary and vaginal progesterone versus vaginal progesterone alone.Methods: This was a retrospective cohort study of singletons pregnancies managed in two tertiary medical centers between September 2011 and May 2017. One center utilized the combined treatment of Arabin cervical pessary and vaginal progesterone (study group) and the second utilized vaginal progesterone approach (control group).Results: During the study period, a total of 202 pregnant women who underwent vaginal ultrasonography between 15 and 29 weeks gestation. They all had short cervical length (≤25 mm). Among them, 94 (46.5%) and 108 (53.5%) patients were in the study and control group, respectively. A significantly higher rate of patients in the study group had either a history of cervical incompetence (9.6 vs. 0.9%, respectively, p = 0.006) or cervical surgery (7.9 vs. 0%, respectively, p = .003). Despite having shorter cervical length at recruitment (14.3 ± 5.9 vs. 16.9 ± 5.7, respectively, p = .002) the rate of spontaneous delivery < 34-week gestation was lower in the study group (7.4 vs. 17.6%, respectively, p = .036) and they delivered 1-week later compared to the control group (37.2 ± 2.1 vs. 36.2 ± 3.7, respectively, p = 0.02).Conclusion: We found that for pregnant women with singletons and who had a short cervical length, the combined treatment of Arabin cervical pessary and vaginal progesterone had lower rate of preterm delivery < 34 weeks of gestation and prolonged gestation compared to those women who were treated with vaginal progesterone alone. Our preliminary findings warrant randomized control studies in order to further illuminate our results.

BACKGROUND: Most major societies do not state a specific recommendation against or in favor of routine umbilical cord gas studies sampling. OBJECTIVE: We aimed to study the correlation between abnormal umbilical cord gas studies (using 5 different definitions) and adverse neonatal outcomes in scheduled nonlaboring term singleton cesarean deliveries. STUDY DESIGN: The medical charts, surgical records, and neonatal charts of all singleton cesarean deliveries at 370/7-416/7 weeks of gestation between January 2009 and May 2018 from a single tertiary center were reviewed. The cohort of singleton cesarean deliveries was divided into those with "normal" vs "abnormal" umbilical cord gas studies with the 5 different definitions: (1) definition A: pH ≤7.15; (2) definition B: pH ≤7.15 and base excess ≤-12 mmol/L; (3) definition C: pH ≤7.1l (4) definition D: pH ≤7.1 and base excess ≤-12 mmol/L, and (5) definition E: pH <7.0 and base excess ≤-12 mmol/L. Adverse neonatal outcomes included Apgar scores at 5 minutes ≤7, neonatal sepsis, blood transfusion, phototherapy, respiratory morbidity (presence of respiratory distress syndrome, transient tachypnea of the newborn infant, mechanical ventilation, need for respiratory support, or meconium aspiration), cerebral morbidity (presence of intraventricular hemorrhage, seizures, or hypoxic-ischemic encephalopathy), necrotizing enterocolitis, or death. Composite adverse outcome was ≥1 of the aforementioned complications. RESULTS: Overall, 3001 singleton cesarean deliveries were included. The rate of abnormal umbilical cord gas studies with the use of definitions A-E was 2.6%, 0.3%, 1.2%, 0.3%, and 0.1%, respectively. The overall rate of adverse neonatal outcome for the entire cohort was 14.43% (433/3001). There was no correlation between abnormal umbilical cord gas studies and composite adverse neonatal outcome with the use of any of the definitions A-E (P=.2, P=.3, P=.2, P=.3, P=.1, respectively). The sensitivity and specificity of abnormal umbilical cord gas studies as a predictor of composite adverse neonatal outcome were calculated for each of the abnormal umbilical cord gas studies definitions; although the sensitivity was extremely low (0-2.07%), the specificity was high (97.2-99.9%) CONCLUSION: Abnormal umbilical cord gas studies are an uncommon finding in cases of singleton term singleton cesarean deliveries and do not correlate with adverse neonatal outcomes. Therefore, the clinical usefulness and cost-effectiveness of obtaining these studies routinely should be questioned.

BACKGROUND: Proper pain control after cesarean delivery is of high clinical importance to the recovery and relief of patients after surgical delivery. OBJECTIVE: We aimed to compare fixed time interval to on-demand regimens of nonopioid analgesics and to assess whether a protocol that is based on intravenous administration is superior to oral administration. STUDY DESIGN: This was a randomized controlled trial performed between April 2017 and May 2018. Patients who underwent elective cesarean delivery were assigned randomly to receive 1 of 3 pain relief protocols for the first 48 hours after surgery: (1) the fixed intravenous protocol included intravenous paracetamol (acetaminophen) 3 times daily with oral ibuprofen twice daily, (2) the fixed oral protocol included oral paracetamol 3 times daily with oral ibuprofen twice daily; if the patient requested additional analgesia, tramadol hydrochloride or dipyrone were given as rescue treatments, (3) the on-demand protocol included oral paracetamol or ibuprofen or dipyrone (based on visual analog scale). Pain intensity was measured and compared with the use of the visual analog scale (range, 0 ([no pain] to 10 [worst pain]). Total doses of pain relief analgesia and maternal and neonatal adverse effects were compared between the groups. RESULTS: The study included 127 women who were assigned randomly to the intravenous protocol group (n=41), oral protocol group (n=43), and on-demand protocol group (n=43). There were no between group differences in maternal and pregnancy characteristics, cesarean delivery indications, or surgical technique. The average visual analog scale score was 6.2±0.8 in the intravenous group, 7.0±1.1 in the oral group, and 7.5±0.7 in the on-demand group, in the first 24 hours (P=.01) and 6.4±0.7, 6.8±0.9, and 7.4±0.7 for the total 48 hours, respectively (P<.001). Mean pain score reduction was higher in the intravenous protocol compared with the fixed oral protocol group (4.7±1.2 vs 4.0±1.4; P=.02). The median doses of pain relief analgesia in the intravenous group were 5 (interquartile range, 5-7), 6 in the oral group (interquartile range, 4-6), and 4 in the on-demand group (interquartile range, 3-6; P=.001) in the first 24 hours and 9 (interquartile range, 7-10), 9 (interquartile range, 7-10), and 7 (interquartile range, 4-9), respectively, for the total 48 hours (P<.001). There were no "between group" differences in neonatal birthweight or maternal and neonatal adverse outcomes. CONCLUSION: Administration of pain relief analgesia (ibuprofen and acetaminophen) in fixed time intervals (intravenous or oral) after cesarean delivery yielded reduced visual analog scale pain scores compared with an on-demand protocol, despite fewer pain relief drugs consumed in the on-demand group.

PURPOSE: We aimed to investigate the impact of early versus late discharge following cesarean delivery (CD) on re-admission rate. METHODS: This is a retrospective cohort study of all CDs performed between 2013 and 2016. Patients who underwent CD between 01/13 and 12/14, were routinely discharged on postoperative day (POD) 3 (early discharge) and were defined as T1 group. Patients who had CD between 01/15 and 12/16 were routinely discharged on POD 4 (late discharge) and were defined as T2 group. Data on re-admission rate and postpartum complications were compared between the groups. RESULTS: As compared to the T2 group (n = 1856), less patients in the T1 group (n = 2020) had ≥ 2 previous CDs (13 vs. 15.6%, respectively; p = 0.02). The T1 group had shorter operative time as compared to the T2 group (p < 0.001). Postoperative complications and re-admission rates were similar between the groups. By logistic regression analysis model only intrapartum complications (RR = 7.87, CI 2.45-25.26, p < 0.001) and prolonged labor (RR = 3.68, CI 1.44-9.39, p = 0.006) were found to be independently associated with postpartum re-admission. CONCLUSIONS: Early discharge after CD (POD 3) seems to be as safe as a more delayed discharge.
