RESUMEN
OBJECTIVES: To explore the obstetric, maternal and neonatal outcome in the subsequent pregnancy after a pregnancy with an accidental uterine extension (AUE) during cesarean delivery (CD), as well as the relationship between the different types of AUE (inferior, lateral and superior). METHODS: A retrospective cohort study of all CD with AUE in a tertiary medical center between 01/2011-01/2022. Women with a prior CD with AUE were compared to a 1:3 ratio matched control group of women with a prior CD without AUE. All AUE were defined in their direction, size and mode of suturing. CD with deliberate uterine extensions were excluded. We evaluated obstetric, maternal and neonatal outcomes in the subsequent pregnancy after a pregnancy with AUE during CD. RESULTS: Comparing women with a prior CD with AUE (n=177) to the matched control group of women with a prior CD without AUE (n=528), we found no significant differences in proportions of uterine rupture or any other major complication or adverse outcome between the groups. There were no significant differences in the outcomes of the subsequent pregnancy in relation to the characteristics of the AUE (direction, size and mode of suturing). CONCLUSIONS: Subsequent pregnancies after AUE are not associated with higher maternal or neonatal adverse outcomes including higher proportions of uterine rupture compared to pregnancies without previous AUE. Different characteristics of the AUE do not impact the outcome.
RESUMEN
OBJECTIVE: This study aimed to determine whether administration of a late preterm (34-36 weeks) course of antenatal corticosteroids (ACS) is associated with improved short-term neonatal outcomes among pregnancies complicated with hypertensive disorders of pregnancy (HDP) who delivered in the late preterm period. STUDY DESIGN: A single tertiary center retrospective cohort study, including pregnant individuals with singleton fetuses who delivered between 34.0 and 36.6 weeks following an HDP diagnosis. Exclusion criteria were major fetal anomalies and treatment with ACS before 34 weeks. Cases were divided into two groups: exposed group, consisting of individuals treated with a late ACS course, and nonexposed group, receiving no ACS. The primary outcome was a composite adverse neonatal outcome, including intensive care unit admission, oxygen treatment, noninvasive positive pressure ventilation, mechanical ventilation, respiratory distress syndrome, transient tachypnea, or apnea of prematurity. Secondary neonatal outcomes included birth weight, Apgar score, intraventricular hemorrhage, necrotizing enterocolitis, bronchopulmonary dysplasia, surfactant use, hypoglycemia, hyperbilirubinemia, sepsis, and neonatal death. Multivariable regression models were used to determine adjusted odds ratio (aOR)and 95% confidence intervals (CIs). RESULTS: Of 7,624 preterm singleton deliveries during the study period, 438 (5.7%) were diagnosed with HDP and delivered between 34.0 and 36.6 weeks. Infants who received ACS were diagnosed more commonly with fetal growth restriction (16.0 vs. 5.6%, p < 0.01) and were delivered at an earlier gestational age (GA) (mean GA: 35.6 vs. 36.3 weeks, p < 0.01). The composite neonatal morbidity did not differ between the groups after adjustments (aOR: 0.97, 95% CI: 0.47, 1.98). Neonatal hypoglycemia and hyperbilirubinemia were more common in the exposed group than in the nonexposed group (46.9 vs. 27.4%; aOR: 2.27; 95% CI: 1.26, 4.08 and 64.2 vs. 46.5%; aOR: 2.08; 95% CI: 1.16, 3.72 respectively). CONCLUSION: In people with HDP, a course of ACS given in the late preterm period did not improve neonatal morbidity. KEY POINTS: · In people with HDP, a late preterm ACS course did not improve neonatal morbidity.. · Respiratory morbidity rate was similar between infants who received late ACS and those who did not.. · Neonatal hypoglycemia and hyperbilirubinemia were more common in infants who received late ACS..
RESUMEN
OBJECTIVE: This study aimed to evaluate whether the suspension of intrapartum maternal oxygen supplementation for nonreassuring fetal heart rate is associated with adverse perinatal outcomes. STUDY DESIGN: A retrospective cohort study, including all individuals that underwent labor in a single tertiary medical center. On April 16, 2020, the routine use of intrapartum oxygen for category II and III fetal heart rate tracings was suspended. The study group included individuals with singleton pregnancies that underwent labor during the 7 months between April 16, 2020, and November 14, 2020. The control group included individuals that underwent labor during the 7 months before April 16, 2020. Exclusion criteria included elective cesarean section, multifetal pregnancy, fetal death, and maternal oxygen saturation <95% during delivery. The primary outcome was defined as the rate of composite neonatal outcome, consisting of arterial cord pH <7.1, mechanical ventilation, respiratory distress syndrome, necrotizing enterocolitis, intraventricular hemorrhage grade 3/4, and neonatal death. The secondary outcome was the rate of cesarean and operative delivery. RESULTS: The study group included 4,932 individuals, compared with 4,906 individuals in the control group. The suspension of intrapartum oxygen treatment was associated with a significant increase in the rate of composite neonatal outcome (187 [3.8%] vs. 120 [2.4%], p < 0.001), including the rate of abnormal cord arterial pH <7.1 (119 [2.4%] vs. 56 [1.1%], p < 0.01). A higher rate of cesarean section due to nonreassuring fetal heart rate was noted in the study group (320 [6.5%] vs. 268 [5.5%], p = 0.03).A logistic regression analysis revealed that the suspension of intrapartum oxygen treatment was independently associated with the composite neonatal outcome (adjusted odds ratio = 1.55 [95% confidence interval, 1.23-1.96]) while adjusting for suspected chorioamnionitis, intrauterine growth restriction, and recent coronavirus disease 2019 exposure. CONCLUSION: Suspension of intrapartum oxygen treatment for nonreassuring fetal heart rate was associated with higher rates of adverse neonatal outcomes and urgent cesarean section due to fetal heart rate. KEY POINTS: · The available data on intrapartum maternal oxygen supplementation are equivocal.. · Suspension of maternal oxygen for nonreassuring fetal heart rate during labor was associated with adverse neonatal outcomes.. · Oxygen treatment might still be important and relevant during labor..
RESUMEN
BACKGROUND: 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. METHODS: 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 pH <7.1, 5 min Apgar score ≤7, and/or neonatal intensive care unit admission. RESULTS: 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 < 0.001) compared with primary MSAF. CONCLUSIONS: 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.

INTRODUCTION: The aim of this study is to compare immediate and long-term obstetrical outcomes of patients who underwent cesarean delivery with and without uterine artery embolization (UAE) for the management of placenta accreta spectrum disorder. MATERIAL AND METHODS: A retrospective case control study including all pregnant women admitted to a single tertiary medical center between December 2001 and May 2018 with a diagnosis of placenta accreta spectrum disorder, who underwent cesarean delivery with and without UAE. Groups were compared for maternal characteristics, operative management, postoperative complication rate and long-term outcomes. Follow up on future obstetrical outcomes was conducted via telephone questionnaire. Non-parametric statistics were used. RESULTS: During the study period, 272 women met the inclusion criteria: 64 (23.53%) and 208 (76.47%) underwent preservative cesarean section with and without UAE, respectively. UAE procedure was associated with a longer operative time (82.5 [68-110] vs 50.5 [39-77] minutes; P = .001), and higher blood loss (2000 (1500-3000) vs 1000 (600-2000) mL; P = .001). Hysterectomy rate was comparable between the groups (9 [14%] vs 35 [16.82%]; P = .88); however, multivariate logistic regression analysis found UAE to be an independent factor associated with lower hysterectomy rate (P = .02). Postoperative complications were more frequent in the UAE group. Follow up was achieved in 29 (59.18%) and 72 (51.79%) of the women with and without UAE, respectively (P = .36). No differences were found in rate of abortions, pregnancy and deliveries between the groups. CONCLUSIONS: Cesarean delivery using UAE in placenta accreta spectrum disorder is associated with a higher rate of operative and postoperative complications. Nevertheless, in cases of severe adherence of the placenta, embolization reduces the need for hysterectomy, allowing future fertility.

A pseudoaneurysm of the uterine artery or its branches is usually a result of vascular trauma during invasive procedures such as a cesarean section, vaginal delivery, myomectomy, hysterotomy, or dilatation and curettage. A uterine artery pseudoaneurysm rupture is a rare, yet life-threatening event. Deep infiltrating endometriosis usually involves a decrease in symptoms and imaging findings throughout pregnancy, with the notable exception of the phenomenon of decidualization. We present the case of a pregnant woman with a recent diagnosis of endometriosis, who conceived spontaneously and presented with disabling pain at 13 weeks' gestation. She was diagnosed with a left, huge (and rapidly growing) retrocervical endometriosis nodule encompassing a uterine artery pseudoaneurysm. Selective transarterial embolization was performed at 22 weeks' gestation owing to enlargement of the pseudoaneurysm sac, and the pseudoaneurysm was obliterated successfully. The patient was followed intensively throughout the pregnancy and the baby was delivered at term by cesarean section. After delivery, the nodule returned to the pregestational size.

KEY MESSAGE: Laboratory characteristics of SARS-CoV-2 infection did not differ between pregnant and non-pregnant women. A trend of lower lymphocyte count was observed in the pregnant women group PURPOSE: Laboratory abnormalities, which characterize SARS-CoV-2 infection have been identified, nevertheless, data concerning laboratory characteristics of pregnant women with SARS-CoV-2 are limited. The aim of this study is to evaluate the laboratory characteristics of pregnant compared to non-pregnant women with SARS-CoV-2 infection. METHODS: A retrospective cohort study of all pregnant women with SARS-CoV-2 who were examined at the obstetric emergency room in a tertiary medical center between March and April 2020. Patients were compared with non-pregnant women with SARS-CoV-2 matched by age, who were examined at the general emergency room during the study period. All patients were confirmed for SARS-CoV-2 on admission. Clinical characteristics and laboratory results were compared between the groups. RESULTS: Study group included 11 pregnant women with SARS-CoV-2, who were compared to 25 non-pregnant controls. Respiratory complaints were the most frequent reason for emergency room visit, and were reported in 54.5% and 80.0% of the pregnant and control groups, respectively (p = 0.12). White blood cells, hemoglobin, platelets, and liver enzymes counts were within the normal range in both groups. Lyphocytopenia was observed in 45.5% and 32% of the pregnant and control groups, respectively (p = 0.44). The relative lymphocyte count to WBC was significantly reduced in the pregnant group compared to the controls [13.6% (4.5-19.3) vs. 26.5% (15.7-29.9); p = 0.003]. C-reactive protein [20(5-41) vs. 14 (2-52) mg/dL; p = 0.81] levels were elevated in both groups but without significant difference between them. CONCLUSION: Laboratory characteristics of SARS-CoV-2 infection did not differ between pregnant and non-pregnant women, although a trend of lower lymphocyte count was observed in the pregnant women group.

PURPOSE: To compare the obstetrical and detailed neonatal outcomes of primipara of advanced maternal age conceiving two sequential singleton pregnancies by IVF with those of primipara conceiving twins by IVF. METHODS: A retrospective study of all primiparous women aged ≤ 38 years and conceived by IVF who delivered sequential singletons or delivered twins at a single tertiary university affiliated medical center between 2011 and 2019. We performed two main comparisons: 1. First vs. second singleton pregnancies. 2. Two singleton pregnancies vs. twin pregnancies. RESULTS: Overall, there were 63 women with consecutive singleton IVF pregnancies. The median age was 40.0 at first pregnancy and 42.0 in the second pregnancy. Pregnancy and delivery complications rates did not differ significantly between the first and the second singleton pregnancies, including gestational hypertensive disorders (7 (11.1%) vs. 4 (6.3%), p = 0.530), gestational diabetes mellitus (13 (20.6%) vs 18 (28.5%), p = 0.410), intrauterine growth restriction (6 (9.5%) vs. 4 (6.3%), p = 0.744), or cesarean delivery (25 (39.7%) vs. 29 (46%), p = 0.589). Rates of delivery before 32 weeks gestation were similar for both first and second singleton pregnancies (1.6%, p > 0.999). The proportion of neonatal adverse outcome in both first and second singleton pregnancies groups was low and did not differ between the groups. Compared with women who delivered sequential singletons, women with twin pregnancies had significantly higher cesarean delivery rates (113 (83.7%) vs. 29 (46%), p < 0.001) and lower gestational ages at delivery (36.2 vs. 38.4, p < 0.001) than women with two singleton deliveries. Adverse neonatal outcomes were significantly higher for twin pregnancies, including birthweight < 1500 g (17 (12.6%) vs. 2 (3.2%), p = 0.036), neonatal intensive care unit admission (57 (42.2%) vs. 4 (6.3%), p < 0.001), neonatal hypoglycemia (23 (17%) vs. 3 (4.8%), p = 0.017), and respiratory distress syndrome (14 (10.4%) vs. 1 (1.6%), p = 0.040). Length of neonatal hospitalization was significantly longer for twins (9 vs. 5 days, p < 0.001). The rate of gestational hypertensive disorders (preeclampsia and gestational hypertension) was similar between the groups, but the rates of severe preeclampsia trended higher among women who carried twins (8 (5.9%) vs. 0, p = 0.057). CONCLUSIONS: Sequential singleton pregnancies at primipara women of advanced maternal age have an overall very good outcome, with no clinically significant difference between the pregnancies. In addition, their outcome is much better compared with twins.

PURPOSE: Information regarding the use of barbed suture in gynecologic surgery is limited. Our aim was to compare maternal morbidity following caesarean deliveries performed with barbed compared with non-barbed suture for uterine closure. METHODS: A historical cohort study from a single tertiary institution. The study group composed of all women that underwent term, uncomplicated singleton caesarean deliveries, where uterine closure was performed with ETHICON's Stratafix®, a polydioxanone barbed suture, compared with caesarean deliveries where uterine closure was performed with ETHICON's VICRYL®, a Polyglactin 910 non-barbed suture. The primary outcomes were the rate of maternal morbidity including the rate of red packed cells transfusion and a composite of infectious morbidity. Operation duration was also evaluated. An analysis restricted to elective caesarean deliveries was performed comparing the suture types. RESULTS: Three thousand and sixty patients were included in the study; 1337 in the study group and 1723 in the control group. There was no significant difference in the rate of the primary outcomes (red packed cells transfusion: 2.5% in the barbed suture vs. 2.1% in the non-barbed suture groups; p = 0.47; composite maternal morbidity: 3.8% vs. 4.8%, respectively; p = 0.18). Barbed suture was associated with reduced risk of postoperative ileus compared with the non-barbed suture (0.3% vs. 1.0%, respectively; p = 0.02) and a longer operation time (31 vs. 29 min, respectively; p < 0.001). In the analysis restricted to elective caesarean deliveries only the duration of operation remained significantly different between the groups. CONCLUSIONS: The rate of short term maternal morbidities among patients undergoing uterine closure with barbed suture during caesarean delivery is similar to the non-barbed suture.

BACKGROUND: Persistently high rates of cesarean deliveries are cause for concern for physicians, patients, and health systems. Prelabor assessment might be refined by identifying factors that help predict an individual patient's risk of cesarean delivery. Such factors may contribute to patient safety and satisfaction as well as health system planning and resource allocation. In an earlier study, neonatal head circumference was shown to be more strongly associated with delivery mode and other outcome measures than neonatal birthweight. OBJECTIVE: In the present study we aimed to evaluate the association of sonographically measured fetal head circumference measured within 1 week of delivery with delivery mode. STUDY DESIGN: This was a multicenter electronic medical record-based study of birth outcomes of primiparous women with term (37-42 weeks) singleton fetuses presenting for ultrasound with fetal biometry within 1 week of delivery. Fetal head circumference and estimated fetal weight were correlated with maternal background, obstetric, and neonatal outcome parameters. Elective cesarean deliveries were excluded. Multinomial regression analysis provided adjusted odds ratios for instrumental delivery and unplanned cesarean delivery when the fetal head circumference was ≥35 cm or estimated fetal weight ≥3900 g, while controlling for possible confounders. RESULTS: In all, 11,500 cases were collected; 906 elective cesarean deliveries were excluded. A fetal head circumference ≥35 cm increased the risk for unplanned cesarean delivery: 174 fetuses with fetal head circumference ≥35 cm (32%) were delivered by cesarean, vs 1712 (17%) when fetal head circumference <35 cm (odds ratio, 2.49; 95% confidence interval, 2.04-3.03). A fetal head circumference ≥35 cm increased the risk of instrumental delivery (odds ratio, 1.48; 95% confidence interval, 1.16-1.88), while estimated fetal weight ≥3900 g tended to reduce it (nonsignificant). Multinomial regression analysis showed that fetal head circumference ≥35 cm increased the risk of unplanned cesarean delivery by an adjusted odds ratio of 1.75 (95% confidence interval, 1.4-2.18) controlling for gestational age, fetal gender, and epidural anesthesia. The rate of prolonged second stage of labor was significantly increased when either the fetal head circumference was ≥35 cm or the estimated fetal weight ≥3900 g, from 22.7% in the total cohort to 31.0%. A fetal head circumference ≥35 cm was associated with a higher rate of 5-minute Apgar score ≤7: 9 (1.7%) vs 63 (0.6%) of infants with fetal head circumference <35 cm (P = .01). The rate among fetuses with an estimated fetal weight ≥3900 g was not significantly increased. The rate of admission to the neonatal intensive care unit did not differ among the groups. CONCLUSION: Sonographic fetal head circumference ≥35 cm, measured within 1 week of delivery, is an independent risk factor for unplanned cesarean delivery but not instrumental delivery. Both fetal head circumference ≥35 cm and estimated fetal weight ≥3900 g significantly increased the risk of a prolonged second stage of labor. Fetal head circumference measurement in the last days before delivery may be an important adjunct to estimated fetal weight in labor management.

OBJECTIVE: To determine whether antenatal corticosteroids administration prior to an elective cesarean section (ECS) at 34-37 weeks gestation is associated with improved neonatal outcome. MATERIALS AND METHODS: A case control study of women with singleton pregnancies who underwent ECS between 34 and 37 weeks of gestation including two groups: (1) study group in which patients were treated with betamethasone prior to ECS (n = 58) and (2) control group matched for gestational age at delivery in which patients did not receive betamethasone (n = 107). Neonatal measures including respiratory distress syndrome (RDS), transient tachypnea of the newborn (TTN), oxygen requirement, admission to the special care unit, hypoglycemia, hyperbilirubinemia and length of hospitalization were determined in both groups. Composite respiratory morbidity was defined as the presence of either RDS, TTN, mechanical ventilation or oxygen requirement. RESULTS: There was no significant difference in the rate of composite respiratory morbidity nor its components between patients with and without betamethasone treatment (25.9 vs. 25.2%, respectively, p = 0.9). CONCLUSION: Antenatal treatment with corticosteroids prior to ECS at 34-37 weeks of gestation did not result in significant reduction in neonatal respiratory morbidity in our cohort of patients.

AIMS: To determine the clinical yield of abdominal ultrasound in the evaluation of elevated liver enzymes (ELEs) in the second and the third trimester of pregnancy. METHODS: A retrospective cohort study including all pregnant women admitted to a single tertiary care center was conducted between April 2011 and January 2015 with ELE. Inclusion criteria included gestational age above 24 weeks and ELEs, abdominal ultrasound report, and live fetus. Exclusion criteria included known maternal liver disease, structural or chromosomal fetal anomalies, and positive serology for viral hepatitis. All patients underwent abdominal ultrasound. A significant finding of this study led to a change in treatment. RESULTS: One hundred and twenty patients (41.8%) met inclusion criteria: 93 (77.5%) had a normal scan and 27 (22.5%) had abnormal findings. Significant ultrasound findings were found only in 2 (1.6%) patients: gallstones in the common bile duct and suspected autoimmune hepatitis. There were no significant differences between patients with and without ultrasound findings in the rate of cholestasis of pregnancy, preeclampsia, chronic hypertension, and gestation diabetes. CONCLUSION: Abdominal ultrasound examination in this population has a low clinical yield. The decision to perform an abdominal ultrasound must be individualized based on the obstetric history, clinical findings, and the level of liver enzymes.

We compared the rates of instrumental delivery in a cohort of nulliparous women at term (n = 19,416), to primiparous women who attempted labour after prior caesarean (TOLAC) (n = 1747). The rate of instrumental deliveries was higher in the TOLAC group compared to nulliparous gravidas (17.3 vs. 15% respectively, p = 0.001). The difference was more prominent for women who eventually had successful vaginal delivery (TOLAC: 23.9% vs. CONTROLS: 17.1%, p < 0.0001 respectively). Based on our results, previous caesarean whether urgent or elective was associated with an increased risk of instrumental delivery in the subsequent pregnancy.

OBJECTIVE: To compare indications for delivery and neonatal morbidities between twins and singletons born between 34 and 35 weeks of gestation. STUDY DESIGN: A prospective observational study was performed in which all infants born between January and August 2008, at Sheba Medical Center at 34 0/7-35 6/7 weeks of gestational age were included. Indications for delivery, infants' morbidities and medical interventions were documented. Twins and singletons were compared for antenatal maternal characteristics, risks of short-term neonatal complications and interventions. RESULTS: One hundred and seventy-three mothers and 229 neonates (114 twins and 115 singletons) were included. Background maternal characteristics as well as the use of antenatal steroids and MgSO4 were similar between the groups. Only 44% of all deliveries were spontaneous, while the rest were indicated deliveries. Twins were born lighter and 31.9% of them were SGA. Nevertheless, singletons were significantly more likely to receive medical interventions such as prolonged oxygen use (>1 day) and phototherapy. All late preterm infants (n=5) needing surfactant administration were singletons. Overall, the risk of needing any medical intervention was significantly higher for singletons compared with twins (OR 1.8, 95% CI 1.02-3.2). CONCLUSIONS: A significant proportion of late preterm births is iatrogenic. Twins and singletons are dissimilar with regards to risks of short-term complications. Despite being born smaller and more SGA, twins are at lower risk of requiring medical intervention in the immediate neonatal period compared with singletons.

OBJECTIVE: The purpose of this study was to determine whether planned vaginal delivery is associated with increased risk of perinatal death and morbidity in twin pregnancies that are complicated by a very low birthweight of the second twin. STUDY DESIGN: We conducted a retrospective cohort study of twin pregnancies in which the second twin's birthweight was ≤1500 g. One hundred ninety-three twin gestations met the study criteria; patients were classified into 2 groups according to the planned mode of delivery: (1) cesarean delivery (n = 142) and (2) vaginal delivery (n = 51). In the vaginal delivery group, 21 pairs were in cephalic-cephalic presentation at the time of delivery; 28 pairs were cephalic-noncephalic, and 2 pairs were noncephalic-noncephalic. Composite adverse neonatal outcome was defined as the presence of neonatal death, respiratory distress syndrome, sepsis, necrotizing enterocolitis, or intraventricular hemorrhage grade 3-4. RESULTS: Trial of vaginal delivery was successful for both twins in 90.5% of cephalic-cephalic twins and 96.4% in cephalic-noncephalic twins. The rate of intraventricular hemorrhage was significantly higher in the vaginal delivery group (29.4% vs 8.5%, respectively; P = .013; adjusted odds ratio [OR], 3.65; 95% confidence interval [CI], 1.32-10.1). The increased risk of intraventricular hemorrhage in the vaginal delivery groups was evident in both twin A (17.6% vs 7.0%; P = .029) and twin B (15.7% vs 4.9%; P = .014); however, these differences were not significant after adjustment for possible confounders (twin A: adjusted OR, 1.79; 95% CI, 0.58-5.55; twin B: adjusted OR, 2.13; 95% CI, 0.63-7.25). In addition, subgroup analysis revealed that both cephalic-cephalic and cephalic-noncephalic twins who were delivered vaginally had increased risk for intraventricular hemorrhage. There were no significant differences between the cesarean and vaginal delivery groups in the rates of Apgar score <7 at 5 minutes, arterial cord pH <7.1, composite adverse neonatal outcome, and neonatal mortality rate. However, the rate of respiratory distress syndrome was significantly lower in the vaginal delivery group (66.7% vs 69%; P = .042; OR, 0.34; 95% CI, 0.12-0.96). CONCLUSION: Vaginal delivery of very low birthweight twins is associated with an increased risk of intraventricular hemorrhage, regardless of presentation. Because of the small sample size and the retrospective cohort design, large prospective randomized studies are needed.

OBJECTIVES: The purpose of this study was to evaluate a novel sonographic scoring system for risk assessment of complications in patients suspected of having morbidly adherent placenta. METHODS: This retrospective study evaluated the association between maternal complications and a grayscale sonographic scoring system for adherent placenta before surgery. Criteria for adherent placenta included uteroplacental and uterobladder demarcation lines and the presence of lacunae. Placentas were classified into 4 stages: stage 0, normal placentation; stage 1, low probability of adherence; stage 2, moderate possibility of adherence; and stage 3, high suspicion of adherence. Placental adherence as assessed by a surgical team, estimated blood loss, and postoperative hospitalization days were determined for each group, as well as the rates of the need for packed blood cells, cryoprecipitate units, and hysterectomy. RESULTS: One hundred nine women were included in the study. Twenty-six (23.8%) women were given a score of stage 0, 22 (20.2%) stage 1, 28 (25.7%) stage 2, and 33 (30.3%) stage 3. Linear regression analysis demonstrated that the sonographic staging was the only variable significantly associated with the number of packed cells or cryoprecipitate units transfused (P< .001) and a clinical diagnosis of adherent placenta (P< .001). In addition, both sonographic staging and a history of cesarean delivery were significantly associated with hysterectomy (P = .01; P = .03, respectively), treatment with any blood products (P< .001; P= .01), and the duration of postoperative hospitalization (P< .001; P = .006). CONCLUSIONS: A scoring system based on simple grayscale parameters may be effective for antenatal risk assessment of maternal complications in cases of suspected morbidly adherent placenta.

OBJECTIVE: Omentin, a newly identified adipokine, enhances insulin mediated glucose uptake in human adipocytes, thus, inducing systemic insulin-sensitizing effect. The aims of this study were to determine whether circulating maternal omentin levels are associated with insulin resistance indices and to assess which compartment, maternal, fetal, or placental, is the source of omentin in maternal circulation. METHODS: Fasting serum glucose, insulin, and omentin were determined in 25 healthy pregnant women at the third trimester, before and 3 days after elective cesarean section. Cord blood omentin was measured in the 25 term neonates. Homeostasis model assessment (HOMA) was used to evaluate insulin sensitivity before and after delivery. RESULTS: Antepartum maternal omentin levels were negatively correlated with insulin levels (r=-0.41, P=0.04) and positively correlated with insulin sensitivity (HOMA%S; r=0.4, P=0.04). Postpartum omentin levels were negatively correlated with maternal body mass index (r=-0.44, P=0.02). Median maternal omentin levels was comparable before and after delivery (57.2, inter-quartile range: 38.2-76.2 ng/mL vs. 53.4, 39.8-69.4 ng/mL, respectively, P=0.25) and highly correlated (r=0.83, P<0.001). Antepartum maternal and neonatal omentin levels did not differ significantly (fetal: 62.2, 44.3-74.2 ng/mL, P=0.77) and did not correlate (P=0.6). CONCLUSIONS: Circulating maternal omentin levels are correlated with insulin resistance indices, suggesting that this adipokine may play a role in metabolic adaptations of normal gestation. The strong correlation between anteparum and postpartum maternal omentin levels, as well as the lack of association between maternal and neonatal omentin levels, suggest that placental or fetal compartments are unlikely as the main source of circulating maternal omentin.

OBJECTIVE: To determine the admission to delivery interval and the rate of immediate delivery in twin versus singleton gestation complicated by spontaneous preterm labor (SPTL). METHODS: A retrospective cohort study of pregnant women presenting with advanced cervical dilatation of 3-5 cm and frequent uterine contractions at 24-34 weeks of gestation was performed. The rate of progression to delivery within 12 h and 24 h, as well as rates of prolonged latency, were compared between twins and singletons gestations. RESULTS: Sixty-nine women were included, of which 25 carried twins and 44 singletons. The overall rate of spontaneous delivery within 12 h and 24 h was 47.8% and 59.4%, respectively, and similar between twins and singletons. Nevertheless, prolonged latency of 10 days or more after presentation was more frequent among twins compared with singletons [10/25 (40%) vs. 7/44 (15.9%), respectively; P=0.026]. Moreover, women carrying twins presenting with advanced cervical dilatation had a better chance of completing a full 2-dose antenatal betamethasone course compared with singletons [19/25 (76%) of twins compared with 21/44 (47.7%) of singletons, odds ratio 3.5, 95% confidence interval 1.16-10.34; P=0.022]. CONCLUSION: Up to 60% of women presenting with advanced cervical dilatation prior to 34 weeks' gestation give birth within 24 h. Nevertheless, women carrying twins have a better chance of completing a betamethasone course and having prolonged latency compared with singletons.

OBJECTIVE: Magnesium sulfate (MgSO4) administered to women at risk for preterm delivery decreases the risk of cerebral palsy in their children. However, the neuroprotective effect of MgSO4 has not been shown in twin gestations. Thus, the aim of this study was to determine the maternal serum levels of magnesium in twin vs. singleton pregnancies following intravenous treatment of MgSO4. METHODS: Case control study including two groups of pregnant women who received intravenous MgSO4: (1) twin gestations (n=83) and (2) singleton pregnancies (n=83). Maternal serum magnesium levels 6 and 24 h after initiation of treatment were determined in both groups. RESULTS: Maternal serum levels of magnesium were significantly lower among patients with twin gestations compared to those with singleton ones 6 h after initiation of treatment (4.6 vs. 4.8 mg/dL, P=0.003). In addition, the rate of pregnant women who obtained therapeutic levels 6 h after initiation of treatment was significantly lower in twin gestations than in singleton ones (36% vs. 58%, P=0.008). Multiple regression analysis revealed that twin gestations were independently and significantly associated with low maternal serum magnesium levels. CONCLUSIONS: Maternal serum concentrations of magnesium are lower in twin pregnancies than in singleton ones following MgSO4 treatment, which might explain the decreased neuroprotective effect of MgSO4 reported in twin pregnancies.

BACKGROUND: Homozygous carriers of factor V Leiden (FVL) have an up to 80-fold increased risk of venous thrombosis, but the risk of obstetric complications in FVL homozygosity is unclear. OBJECTIVES: To compare obstetric and thromboembolic complications among factor V Leiden (FVL) homozygous and heterozygous carriers treated with prophylactic dose anticoagulation during pregnancy. METHODS: In this retrospective case-control study we performed a chart review for the years 2004-2010 of homozygous and heterozygous FVL carriers who were treated with low molecular weight heparin (LMWH) at a dose of 0.6 mg/kg/day during pregnancy. Adverse outcomes included thromboembolic and obstetric complications. A composite adverse obstetric outcome was defined as the presence of at least one of the following: late intrauterine fetal demise, severe intrauterine growth restriction (< 5th percentile), preeclampsia, and placental abruption. Pregnancy outcomes of homozygous and heterozygous FVL carriers were compared. RESULTS: We compared the pregnancies of 13 homozygous FVL women with those of 82 heterozygous FVL carriers. Thromboembolic events occurred only in heterozygous FVL controls. Gestational age and birth weight were similar. The composite adverse obstetric outcome rate was higher for homozygous compared with heterozygous FVL carriers (23.1% vs. 11%, respectively), although not statistically significant. A trend for prematurity among homozygous FVL patients was evident, with 2/13 women (15.3%) in the homozygous FVL group giving birth before 34 weeks gestation, compared with only 2/82 (2.3%) in the heterozygous group. CONCLUSIONS: Pregnancy outcome was similar for homozygous and heterozygous FVL carriers on LMWH thromboprophylaxis. The overall likelihood of thromboembolic complications was low. Thromboprophylaxis may decrease the risk for placental and thromboembolic complications in homozygous FVL patients to a similar level as in heterozygotes.
