Abstract
Preterm birth occurs in approximately 10% of all births in the United States and is a major contributor to perinatal morbidity and mortality (). Prelabor rupture of membranes (PROM) that occurs preterm complicates approximately 2-3% of all pregnancies in the United States, representing a significant proportion of preterm births, whereas term PROM occurs in approximately 8% of pregnancies (). The optimal approach to assessment and treatment of women with term and preterm PROM remains challenging. Management decisions depend on gestational age and evaluation of the relative risks of delivery versus the risks (eg, infection, abruptio placentae, and umbilical cord accident) of expectant management when pregnancy is allowed to progress to a later gestational age. The purpose of this document is to review the current understanding of this condition and to provide management guidelines that have been validated by appropriately conducted outcome-based research when available. Additional guidelines on the basis of consensus and expert opinion also are presented. This Practice Bulletin is updated to include information about diagnosis of PROM, expectant management of PROM at term, and timing of delivery for patients with preterm PROM between 34 0/7 weeks of gestation and 36 6/7 weeks of gestation.

Abstract
OBJECTIVE To determine the management of patients with term prelabor rupture of membranes. METHODS Synthesis of the literature from the PubMed and Cochrane databases and the recommendations of French and foreign societies and colleges. RESULTS Term prelabor rupture of membranes is considered a physiological process until 12 h have passed since rupture (professional consensus). In cases of expectant management and with a low rate of antibiotic prophylaxis, home care may be associated with an increase in neonatal infections (LE3), compared with hospitalization, especially for women with group B streptococcus (GBS) colonization (LE3). Home care is therefore not recommended (grade C). In the absence of spontaneous labor within 12 h of rupture, antibiotic prophylaxis may reduce the risk of maternal intrauterine infection but not of neonatal infection (LE3). Its use after 12 h of rupture in term prelabor rupture of the membranes is therefore recommended (grade C). When antibiotic prophylaxis is indicated, intravenous beta-lactams are recommended (grade C). Induction of labor with oxytocin (LE1), prostaglandin E2 (LE1), or misoprostol (LE1) is associated with shorter rupture-to-delivery intervals than expectant management; immediate induction is not, however, associated with lower rates of neonatal infection (LE1), even among women with a positive GBS vaginal swab (LE2). Thus, expectant management can be offered without increasing the risk of neonatal infection (grade B). Induction of labor is not associated with either an increase or decrease in the cesarean rate (LE2), regardless of parity (LE2) or Bishop score at admission (LE3). Induction can thus be proposed without increasing the risk of cesarean delivery (grade B). No induction method (oxytocin, dinoprostone, misoprostol, or Foley catheter) has demonstrated superiority over any another method for reducing rates of intrauterine or neonatal infection or of cesarean delivery or for shortening the rupture-to-delivery intervals, regardless of parity or the Bishop score. CONCLUSION Term prelabor rupture of membranes is a frequent event. A 12-hour interval without onset of spontaneous labor was chosen to differentiate a physiological condition from a potentially unsafe situation that justifies antibiotic prophylaxis. Expectant management or induction of labor can each be proposed, even in case of positive screening for group streptococcus. The decision should depend on the woman's wishes and maternity unit organization (professional consensus).

Abstract
INTRODUCTION Term prelabor rupture of membranes (TPROM) occurs in approximately 8 % of pregnancies. This condition regularly requires medical intervention such as induction of labor. The actual data concerning cervical ripening in case of TPROM does not favor any of the available techniques. This is the first study comparing dinoprostone versus Foley catheter for cervical ripening in TPROM. MATERIALS AND METHODS We conducted a retrospective before-after study. We enrolled all the patients with confirmed TPROM after 37 weeks of gestation (WG) who required cervical ripening. Women were included if they had a singleton fetus in cephalic presentation, with unfavorable cervix (Bishop ≤ 6). Patients were excluded if they had a previous uterine surgery, a multiple pregnancy, contraindication to vaginal delivery, spontaneous labor or favorable cervix (Bishop > 6). During the first period (2015), the protocol of cervical ripening involved dinoprostone (prostaglandins E2) by vaginal administration (vaginal gel or pessary). During the second period (2016-2017), the protocol of cervical ripening involved Foley catheter (FC). The primary outcome was the rate of cesarean section. RESULTS Two hundred and thirty-eight patients were included for the analysis: 131 in the first period (dinoprostone group) and 107 in the second period (foley catheter group). There was no significant difference between the two groups regarding the mode of delivery (cesarean section: 206 % vs 13 %, p = 016). Concerning tolerance, the were no difference in the rates of postpartum hemorrhage, maternal per-partum fever and endometrisis. Neonatal outcomes were similar between the two groups. The induction to delivery interval was lower with dinoprostone (20,3 h versus 26,0 h, p = 0001). The mean duration of labor was also significantly different (6,9 h for dinoprostone group versus 8,7 h for FC group, p = 001). CONCLUSION Cervical ripening in case of TPROM after 37 W G with Foley catheter seems to be a safe technique with similar outcomes to prostaglandins regarding the mode of delivery.

Abstract
INTRODUCTION To investigate the safety of balloon catheter for cervical ripening in women with term pre-labor rupture of membranes (PROM) and to compare the incidence of maternal and neonatal infections in women with PROM and women with intact membranes undergoing cervical ripening with a balloon catheter. MATERIAL AND METHODS This retrospective cohort study of 1923 women with term singleton pregnancy and an unfavorable cervix undergoing cervical ripening with a balloon catheter was conducted in Helsinki University Hospital between January 2014 and December 2018. For each case of PROM, two controls were assigned. The main outcome measures were the rates of maternal and neonatal infections. Statistical analyses were performed by SPSS. RESULTS In all, 641 (33.3%) women following PROM and 1282 (66.6%) women with intact amniotic membranes underwent labor induction. The rates of intrapartum infection (3.7% vs 7.7%; P = .001) and neonatal infection (1.7% vs 3.8%; P = .01) were not increased in women induced by balloon catheter following PROM. Intrapartum infections were associated with nulliparity (odds ratio [OR] 3.3, 95% confidence interval [CI] 1.6-6.5), history of previous cesarean section (OR 2.8, 95% CI 1.2-6.4), extended gestational age ≥41 weeks (OR 1.9, 95% CI 1.2-3.0) and an induction to delivery interval of 48 hours or more (OR 2.0, 95% CI 1.2-3.3). The risk of neonatal infection was associated with nulliparity (OR 3.3, 95% CI 1.4-8.0), gestational age ≥41 weeks (OR 1.9, 95% CI 1.09-3.36) and induction to delivery interval of 48 hours or more (OR 3.4, 95% CI 1.9-6.0). CONCLUSIONS Use of balloon catheter in women with term PROM appears safe and was not associated with increased maternal or neonatal infectious morbidity.

Prelabor rupture of membranes and the association with cerebral palsy in term born children: a national registry-based cohort study. BMC Pregnancy Childbirth 2020; 20:67.

Abstract
BACKGROUND Guidelines regarding management of prelabor rupture of membranes (PROM) at term vary between immediate induction and expectant management. A long interval between PROM and delivery increases the risk for perinatal infections. Severe perinatal infections are associated with excess risk for cerebral palsy (CP) and perinatal death. We investigated if increasing intervals between PROM and delivery were associated with perinatal death or CP. METHODS Eligible to participate in this population-based cohort-study were term born singletons without congenital malformations born in Norway during 1999-2009. Data was retrieved from the Medical Birth Registry of Norway (MBRN) and the Cerebral Palsy Register of Norway. In line with the registration in the MBRN, intervals between PROM and delivery of more than 24 h was defined as 'prolonged' and intervals between 12 and 24 h as 'intermediate'. Outcomes were stillbirth, death during delivery, neonatal mortality and CP. Logistic regression was used to calculate odds ratio (OR) with 95% confidence intervals (CI) for adverse outcomes in children born after prolonged and intermediate intervals, compared with a reference group comprising all children born less than 12 h after PROM or without PROM. RESULTS Among 559,972 births, 34,759 children were born after intermediate and 30,332 were born after prolonged intervals. There was no association between increasing intervals and death during delivery or in the neonatal period, while the prevalence of stillbirths decreased with increasing intervals. Among children born after intermediate intervals 38 (0.11%) had CP, while among those born after prolonged intervals 46 (0.15%) had CP. Compared with the reference group, the OR for CP was 1.16 (CI; 0.83 to 1.61) after intermediate and 1.61 (CI; 1.19 to 2.18) after prolonged intervals. Adjusting for antenatal factors did not affect these associations. Among children with CP the proportion with diffuse cortical injury and basal ganglia pathology on cerebral MRI, consistent with hypoxic-ischemic injuries, increased with increasing intervals. CONCLUSION Intervals between PROM and delivery of more than 24 h were associated with CP, but not with neonatal mortality or death during delivery. The inverse association with stillbirth is probably due to reverse causality.

Abstract
Background Prolonged latent phase of labor is associated with adverse maternal and neonatal outcomes. Preliminary data indicate that labor induction for prolonged latent phase may reduce cesarean delivery. We performed a study powered to Cesarean delivery to evaluate labor induction compared to expectant management in full term nulliparas hospitalized for persistent contractions but non-progressive to established labor after an overnight stay. Methods From 2015 and 2017, nulliparas, ≥ 39 weeks’ gestation with prolonged latent phase of labor (persistent contractions after overnight hospitalization > 8 h), cervical dilation ≤3 cm, intact membranes and reassuring cardiotocogram were recruited. Participants were randomized to immediate induction of labor (with vaginal dinoprostone or amniotomy or oxytocin as appropriate) or expectant management (await labor for at least 24 h unless indicated intervention as directed by care provider). Primary outcome measure was Cesarean delivery. Results Three hundred eighteen women were randomized (159 to each arm). Data from 308 participants were analyzed. Cesarean delivery rate was 24.2% (36/149) vs. 23.3%, (37/159) RR 1.0 95% CI 0.7–1.6; P = 0.96 in induction of labor vs. expectant arms. Interval from intervention to delivery was 17.1 ± 9.9 vs. 40.1 ± 19.8 h; P < 0.001, intervention to active labor 9.6 ± 10.2 vs. 29.6 ± 18.5 h; P < 0.001, active labor to delivery 7.6 ± 3.6 vs. 10.5 ± 7.2 h; P < 0.001, intervention to hospital discharge 2.4 ± 1.2 vs. 2.9 ± 1.4 days; P < 0.001 and dinoprostone use was 19.5% (29/149) vs. 8.2% (13/159) RR 2.4 95% CI 1.3–4.4; P = 0.01 in IOL compared with expectant arms respectively. Intrapartum oxytocin use, epidural analgesia and uterine hyperstimulation syndrome, postpartum hemorrhage, patient satisfaction on allocated intervention, during labor and delivery and baby outcome were not significantly different across trial arms. Conclusions Induction of labor did not reduce Cesarean delivery rates but intervention to delivery and to hospital discharge durations are shorter. Patient satisfaction scores were similar. Induction of labor for prolonged latent phase of labor can be performed without apparent detriment to expedite delivery. Trial registration Registered in Malaysia National Medical Research Register (NMRR-15-16-23,886) on 6 January 2015 and the International Standard Randomised Controlled Trials Number registry, registration number ISRCTN14099170 on 5 Nov 2015.

Abstract
Obstetrician-gynecologists, in collaboration with midwives, nurses, patients, and those who support them in labor, can help women meet their goals for labor and birth by using techniques that require minimal interventions and have high rates of patient satisfaction. Many common obstetric practices are of limited or uncertain benefit for low-risk women in spontaneous labor. For women who are in latent labor and are not admitted to the labor unit, a process of shared decision making is recommended to create a plan for self-care activities and coping techniques. Admission during the latent phase of labor may be necessary for a variety of reasons, including pain management or maternal fatigue. Evidence suggests that, in addition to regular nursing care, continuous one-to-one emotional support provided by support personnel, such as a doula, is associated with improved outcomes for women in labor. Data suggest that for women with normally progressing labor and no evidence of fetal compromise, routine amniotomy need not be undertaken unless required to facilitate monitoring. The widespread use of continuous electronic fetal monitoring has not been shown to significantly affect such outcomes as perinatal death and cerebral palsy when used for women with low-risk pregnancies. Multiple nonpharmacologic and pharmacologic techniques can be used to help women cope with labor pain. Women in spontaneously progressing labor may not require routine continuous infusion of intravenous fluids. For most women, no one position needs to be mandated or proscribed. Obstetrician-gynecologists and other obstetric care providers should be familiar with and consider using low-interventional approaches, when appropriate, for the intrapartum management of low-risk women in spontaneous labor. Birthing units should carefully consider adding family-centric interventions that are otherwise not already considered routine care and that can be safely offered, given available environmental resources and staffing models. These family-centric interventions should be provided in recognition of the value of inclusion in the birthing process for many women and their families, irrespective of delivery mode. This Committee Opinion has been revised to incorporate new evidence for risks and benefits of several of these techniques and, given the growing interest on the topic, to incorporate information on a family-centered approach to cesarean birth.

Abstract
OBJECTIVE To synthesize current knowledge on definition, frequency, morbidity and risk factors related to term prelabor rupture of membranes. METHODS The MedLine database, the Cochrane Library and French and foreign guidelines from 1980 to 2019 have been consulted. RESULTS Term rupture of membranes is defined by the rupture of the membranes after 37 weeks of gestation (WG). Term prelabor rupture of membranes is defined by the rupture of membranes prior to the onset of labor after 37 WG. According to unpublished data from the 2016 French National Perinatal Survey, 26,5% of women with singleton pregnancies had a term rupture of membranes before their admission into labor ward. We were not able to assess if those were "prelabor" or not (LE3). Among women admitted with term rupture of membranes, 35,6% were still not in labor 12hours after the rupture i.e. 8,9% of all singleton pregnancies (LE3). Reported rates of term prelabor rupture of membranes vary between 6 and 22% in singleton pregnancies (LE3). Term prelabor rupture of membranes is associated with a risk of fever before (LE3), during (LE3) and after labor (LE3), as well as intrauterine and neonatal infection (LE3). The frequency of these complications in the context of a routine antibiotic prophylaxis is unknown. The expert group chose a delay of 12hours without spontaneous labor to differentiate a physiological situation from a potentially risky situation that could justify a medical intervention (Professional consensus). Risk factors for term prelabor rupture of membranes include history of term prelabor rupture of membranes (LE3), nulliparity (LE3), uterine contractions requiring treatment (LE3) and first trimester bleeding (LE3). CONCLUSION Data on frequency, risk factors and morbidity of term prelabor rupture of membranes are limited or of poor quality.

Abstract
OBJECTIVE To assess the effect of immediate induction versus expectant management on maternal and neonatal outcomes in case of term prelabor rupture of membranes. METHODS We searched Medline Database, Cochrane Library and consulted international guidelines. RESULTS In case of term prelabor rupture of membranes, induction of labor is associated with shorter rupture of membranes to delivery intervals when compared to expectant management, if induction is conducted with oxytocin (LE2), prostaglandin E2 (LE2) or misoprostol (LE2), but not when induction is conducted with Foley® catheter (LE2), osmotic dilatator (LE2) or acupuncture (LE2). The strongest evidence to date comes from a large international randomized study, the TERMPROM study, which included over 5000 women between 1992 and 1995. This study compared immediate induction with oxytocin or prostaglandin E2 to expectant management up to 96hours, followed by induction by oxytocin or prostaglandin E2. Immediate induction was not associated with a decreased neonatal infection rate (LE1), even among women with a positive streptococcus B vaginal swab (LE2). Thus, expectant management can be offered without increasing the neonatal infection risk (Grade B). Induction with oxytocin was associated with a decreased risk of intra-uterine infection and postpartum fever in the TERMPROM study (LE2), however, this study had significant limitations concerning this outcome (unknown streptococcus B status and low rate of prophylactic antibiotics), and this association was not found in other smaller studies. This decrease was not observed with induction by prostaglandin E2. In the TERMPROM study, induction was not associated with an increase or decrease in the rate of cesarean section (LE2), whatever the parity (LE2) or Bishop score at admission (LE3). Induction can thus be proposed without increasing the cesarean section risk (Grade B). There is no study evaluating expectant management over 4 days. CONCLUSION In case of term prelabor rupture of membranes, induction can be offered without increasing the cesarean section risk (Grade B). Expectant management can be offered without increasing the neonatal infection risk (Grade B), even among women with a positive streptococcus B vaginal swab (Professional consensus). The optimal moment of induction will therefore be guided by the maternity wards organization and women's preference after having informed them of the risks and benefits associated with induction and expectant management (Professional consensus). In case of meconial fluid or term prelabor rupture of membranes>4 days, induction must be offered (Professional consensus).

Abstract
OBJECTIVE To evaluate safety of home care, clinical and biological initial examination and effectiveness of prophylactic antibiotic in preventing maternal and neonatal infectious complications in women with term prelabor rupture of membranes. MATERIALS AND METHODS The MedLine database, the Cochrane Library and the recommendations from the French and foreign obstetrical societies or colleges have been consulted. RESULTS In case of expectant management and low rate of antibiotic prophylaxis coverage, home care compared to hospitalization could be associated with an increase in neonatal infections (LE3), especially when colonized with Group B Streptococcus (GBS) (LE3). Home care is therefore not recommended (Grade C). Studies investigating the initial clinical-biological examination are sparse. The initial examination should search for signs of intra-uterine infection. Repeated digital examination before and during labor is associated with an increased risk of intra-uterine infection (LE3). It is therefore recommended to limit the number of digital examinations before and during labor (Grade C). A GBS-positive vaginal swab is strongly associated with the risk of intra-uterine and neonatal infection (LE3) independently of the type management (induction vs. expectant management) and the mode of induction (oxytocin or prostaglandin) (LE3). When the GBS-positive vaginal swab has not been performed between 34 and 38 weeks, it is recommended to perform it on admission (Professional consensus). The diagnostic performance of the CRP and white blood cell count for the prediction of neonatal infection is low (LE3). If these tests are used, the negative predictive value of the CRP should be preferred (Professional consensus). In case of term prelabor rupture of membranes after 12hours, prophylactic antibiotics could reduce the rate of intra-uterine infection without reducing the risk of neonatal infection (LE3). Their use in term prelabor rupture of membranes after 12hours is therefore recommended (Grade C). When prophylactic antibiotics are indicated, intravenous beta-lactamine is the preferred option (Grade C). CONCLUSION Overall, the current data on initial management of term prelabor rupture of membranes are of low evidence level.

Abstract
OBJECTIVES To assess the studies comparing induction methods in women with term prelabor rupture of the membranes and establish if one is superior to the others. METHODS The MedLine database, the Cochrane Library and the recommendations from the French and foreign obstetrical societies or colleges have been consulted. RESULTS The included studies compared medical induction methods: oxytocin (intravenous), dinoprostone (vaginal gel, pessary or intracervical gel), and misoprostol (oral or vaginal route); and a mechanical induction method: the Foley catheter. The primary outcome measures were: labor induction to delivery interval, number of women delivered within 12 or 24hours of initiation of induction and cesarean delivery rate. The small sample size of the included studies as well as the limited number of reported complications does not provide a reasonable basis for concluding on the secondary outcome measures: pyrexia, chorioamnionitis, uterine tachysystole, Apgar scores of<7 at 5minutes. Induction of labor with misoprostol (oral and vaginal) reduced the labor induction to delivery interval compared with dinoprostone (LE2). This interval was unchanged when comparing induction with oxytocin and Foley catheter (LE2). The data comparing this interval in women induced with dinoprostone versus oxytocin and misoprostol versus oxytocin is limited or inconsistent. The cesarean delivery rate was comparable in women induced with dinoprostone (vaginal gel) versus oxytocin (LE2), misoprostol (oral and vaginal route) versus oxytocin (LE2), Foley catheter versus oxytocin (LE2), misoprostol versus dinoprostone (LE2) and misoprostol versus Foley catheter (LE2). The number of women delivered within 24hours of initiation of induction was comparable when induced with oral misoprostol versus oxytocin (LE2) and Foley catheter versus oxytocin (LE2). There is a lack of data for this outcome when comparing dinoprostone versus oxytocin, vaginal misoprotsol versus oxytocin, and misoprostol (oral and vaginal) versus dinoprostone. No induction method is superior to another for nulliparous women or women with unfavorable cervix (LE2). CONCLUSION The superiority of an induction method, in terms of effectiveness or safety, could not be established with the current available data for women with term prelabor rupture of the membranes. An increased risk of chorioamnionitis due to induction using Foley catheter could not be ruled out by the available data. All medical methods are suitable for inducing women with term prelabor rupture of the membranes (Grade B).

Abstract
INTRODUCTION Premature rupture of membranes (PROM) occurs at term in 8% of pregnancies. Several studies have demonstrated that the risk of chorioamnionitis and neonatal sepsis increases with duration of PROM. Decreasing the time interval between PROM and delivery is associated with lower rates of maternal infections. In case of an unfavourable cervix, the use of prostaglandin for cervical maturation demonstrates some advantages over oxytocin. The use of double balloon catheter in reduction of PROM duration has not been evaluated in the literature. METHODS AND ANALYSIS We are conducting a prospective, monocentric, randomised clinical trial on pregnant women with an unfavourable cervix showing PROM at term (RUBAPRO).After 12-24 hours of PROM, women are randomly assigned to one group treated with a double balloon catheter for 12 hours, with oxytocin administered after 6 hours or to the control group treated with 24 hours of vaginal prostaglandin followed by oxytocin infusion alone. Patients (n=80) are randomised at a 1:1 ratio with stratification on parity.The inclusion criteria are a Bishop score of <6, cephalic presentation at term and confirmed PROM. Women with suspected chorioamnionitis; group B streptococcus (GBS) carrier; a history of caesarean delivery or any contraindication for vaginal delivery are excluded.The time from induction to delivery is the primary outcome. Secondary outcomes were mode of delivery, maternofetal morbidity and the effect of parity on strategies for reduction of PROM duration.To sufficiently demonstrate a difference (10 hours) between groups-with a statistical power of 90% and a two-tailed α of 5%-40 patients per group will be required. ETHICS AND DISSEMINATION Written informed consent is required from participants.National Ethics Committee approval was obtained in August 2017. The results will be published in a peer-reviewed journal and presented at relevant conferences. Access to raw data will be available only to members of the research team. TRIAL REGISTRATION NUMBER NCT03310333.

Abstract
Background World Health Organization recommended timely initiation of breastfeeding within the first hour of delivery. Less than half of newborn babies (43%) receive the benefits of immediate breastfeeding in the world. In East Africa and Ethiopia, the prevalence of early initiation of breastfeeding was 61.82 and 73%, respectively. But, the prevalence of early initiation of breastfeeding was not assessed in relation to the duration of term premature rupture of the membrane in Ethiopia. Therefore, the aim of this study was to assess the effect of the latency period of term premature rupture of the membrane on early initiation of breastfeeding in Southern Ethiopia, 2017. Methods The study was conducted in Southern Ethiopia public hospitals by using facility based prospective follow up study from 20th February to 20th August 2017. Then, based on the duration of latency period of term premature rupture of the membrane, 98 and 294 mothers with prolonged and short latency period were followed until the initiation of breastfeeding respectively. Logistic regression analysis was performed to see the association between predictor and outcome variables. Adjusted odds ratio, with 95% CI, was calculated for each independent variable to check the adjusted association between independent variables and dependent variable. The statistical significance was set at P < =0.05. Results From a total of 91 mothers with prolonged latency period of premature rupture of membrane, 66.0% of them initiated breastfeeding after 1 h of birth. One the other hand, from 289 women with short latency period, 65.7% of them initiated breastfeeding within 1 h of delivery. The odds of initiation of breastfeeding within 1 h of delivery was higher in mothers with a short latency period of term premature rupture of membrane as compared to a prolonged latency period (AOR = 4.169: 95% CI; [1.933, 8.991]). Other variables such as educational status, wealth index, and place of residence were also independent predictors of initiation of breastfeeding. Conclusion This study pointed out that women with short latency period of premature rupture of the membrane were more likely to initiate breastfeeding within an hour of delivery than women with prolonged latency period. Therefore, this finding suggested that women with prolonged premature rupture of membrane need special attention to increase early initiation breastfeeding.

Abstract
OBJECTIVE To study the incidence of histological chorioamnionitis (HCA) in term pregnancies according to labor onset. STUDY DESIGN During 2013-6, term pregnancy placentas were prospectively sent to histopathology evaluation, and compared between patients with spontaneous onset labor, pre-labor ROM, labor induction and elective cesarean deliveries. RESULTS A total of 260 placentas were obtained, 65 from each group. Rates of HCA for the spontaneous labor, PROM, induction and CD groups were: 49, 32, 24 and 4%, respectively (p < 0.001). Composite neonatal outcome was non-significant between the study groups, and between cases with and without HCA. In a logistic regression model, after controlling for parity - gestational age, mode of delivery, ROM > 12 h and spontaneous onset of labor were found to be independent risk factors for HCA. CONCLUSION HCA at term is prevalent in spontaneous labor and supports the association between the inflammatory processes and activation of the physiological signals of parturition.

Abstract
Objective: To determine predictors for cesarean delivery (CD) in pregnancies complicated by preterm premature rupture of membranes (PPROM) with an intention for vaginal delivery.Materials and methods: A retrospective cohort analysis of all singleton, preterm deliveries (24 + 0 to 36 + 6 weeks) following PPROM (2007-2014). Exclusion criteria included: cases intended for CD prior to delivery; short interval from PPROM to delivery (<24 hours); cervical dilatation upon admission ≥4 cm; and major fetal anatomical/chromosomal abnormalities. Potential CD predictors were evaluated by univariate followed by multivariate regression analysis.Results: Overall, 465 deliveries met inclusion criteria. Of them, 53 (11.4%) ended with CD. Women in the CD group delivered at an earlier gestational age (34 versus 35 weeks) with lower birth weights (2115 versus 2386 grams), p < .05 for both. On univariate analysis, smaller cervical dilatation upon admission and prior to delivery, longer PPROM to delivery interval and delivery indication were the only significant determinants associated CD (p < .001 for all). On multivariable regression analysis, only la rger cervical dilatation prior to delivery remained an independent factor for lower rates of CD (aOR 0.15, 95% CI 0.08-0.28, p < .001).Conclusion: Small cervical dilatation prior to delivery is an independent risk factor for CD in pregnancies complicated by PPROM.

Abstract
Introduction: The aim of this study was to assess the success rate of a trial of labor after a previous cesarean section (TOLAC) in the settings of premature rupture of membranes (PROM) and to compare conservative management with spontaneous labor and induction of labor.Methods: This was a retrospective cohort study conducted in a single tertiary care center between January 2011 and March 2017. Women with singleton pregnancy and a previous cesarean section (CS) who presented with PROM and underwent TOLAC were included. Outcomes and rate of successful vaginal delivery after induction of labor were compared to conservative treatment and spontaneous labor.Results: Among 830 women who met the inclusion criteria, 723 (87.1%) had a spontaneous onset of labor following PROM and 107 (12.9%) had an induction of labor. The rate of successful TOLAC was similar between the groups (75.7 vs. 81.6%, respectively, p = .22). However, induction of labor was associated with an increased risk for uterine rupture (1.87 vs. 0.96%, p < .001), operative complications (6.7 vs. 2.3%, p < .001), and composite maternal postpartum complications (21.4 vs. 10.7%, respectively, p = .014) compared to conservative management with spontaneous initiation of labor. There was no difference in neonatal outcome between the groups.Conclusion: Induction of labor following PROM in women with a previous CS is associated with high successful vaginal delivery rate. However, the risk for uterine rupture and operative and maternal complications is significantly increased compared to spontaneous initiation of labor.

Abstract
OBJECTIVE To identify the determinants of term premature rupture of membrane in Southern Ethiopia public hospitals, 2017. RESULTS Seventy-five cases and 223 controls women were enrolled for the study. Two hundred eighty-four (95.3%) participants were admitted at the gestational age of above 40, and the rest, 14 (4.7%), were admitted at 37-40 weeks of gestation. The current study identified wealth index and inter-birth interval as preventive predictors, but smoking and hypertension during pregnancy were identified as positive determinants of premature rupture of membrane. This finding is supported by multiple logistic regression analysis result of wealth index (AOR: 0.102, 95% CI [0.033, 0.315]), inter-birth interval (AOR: 0.251, 95% CI [0.129, 0 0.488]), smoking (AOR: 17.053, 95% CI [2.145, 135.6]), and hypertension (AOR: 8.92, 95% CI (1.91, 41.605]). The association between PROM and its determinants indicated that evidence-based interventions should be needed and designed to have very high wealth index, and optimal interbirth interval, and prevent smoking and hypertension during pregnancy to decrease PROM occurrence in the study settings. Hence, we recommended that integration of prevention mechanism of modifiable determinants to the obstetrics health care system will reduce premature ruptures of a membrane.

Abstract
Cervical ripening is often the first component of labor induction and is used to facilitate the softening and thinning of the cervix in preparation for labor. Common methods used for cervical ripening include both mechanical (e.g., Foley or Cook catheters) and pharmacologic (e.g., prostaglandins) methods. The choice of method(s) for ripening should take into account the patient's medical and obstetric history, clinical characteristics, and risk of adverse effects if uterine tachysystole were to occur. In this narrative review, we highlight the differences between the prostaglandins dinoprostone and misoprostol with respect to pharmacology and pharmacokinetics, efficacy, and potential safety concerns. Practical guidance on choosing an appropriate prostaglandin agent for cervical ripening and labor induction is provided via the use of clinical vignettes. Considering the advantages and disadvantages of each preparation allows clinicians to individualize treatment, depending on the indications for induction and unique characteristics of each patient.

Abstract
BACKGROUND Extreme ambient temperatures have been linked to preterm birth. Preterm premature rupture of membranes is a common precursor to preterm birth but is rarely studied in relation to temperature. METHODS We linked 15,381 singleton pregnancies with premature rupture of membranes from a nationwide US obstetrics cohort (2002-2008) to local temperature. Case-crossover analyses compared daily temperature during the week preceding delivery and the day of delivery to 2 control periods, before and after the case period. Conditional logistic regression models calculated the odds ratio (OR) and 95% confidence intervals (CIs) of preterm and term premature rupture of membranes for a 1°C increase in temperature during the warm (May-September) and cold (October-April) season separately after adjusting for humidity, barometric pressure, ozone, and particulate matter. RESULTS During the warm season, 1°C increase during the week before delivery was associated with a 5% (95% CI, 3%, 6%) increased preterm premature rupture of membranes risk, and a 4% (95% CI, 3%, 5%) increased term premature rupture of membranes risk. During the cold season, 1°C increase was associated with a 2% decreased risk for both preterm (95% CI, 1%, 3%) and term premature rupture of membranes (95% CI, 1%, 3%). The day-specific associations for the week before delivery were similar, but somewhat stronger for days closer to delivery. CONCLUSIONS Relatively small ambient temperature changes were associated with the risk of both preterm and term premature of membranes. Given the adverse consequences of premature rupture of membranes and concerns over global climate change, these findings merit further investigation.

Abstract
BACKGROUND More than 150,000 pregnant women in England and Wales have their labour induced each year. Multiple pharmacological, mechanical and complementary methods are available to induce labour. OBJECTIVE To assess the relative effectiveness, safety and cost-effectiveness of labour induction methods and, data permitting, effects in different clinical subgroups. METHODS We carried out a systematic review using Cochrane methods. The Cochrane Pregnancy and Childbirth Group's Trials Register was searched (March 2014). This contains over 22,000 reports of controlled trials (published from 1923 onwards) retrieved from weekly searches of OVID MEDLINE (1966 to current); Cochrane Central Register of Controlled Trials (The Cochrane Library); EMBASE (1982 to current); Cumulative Index to Nursing and Allied Health Literature (1984 to current); ClinicalTrials.gov; the World Health Organization International Clinical Trials Registry Portal; and hand-searching of relevant conference proceedings and journals. We included randomised controlled trials examining interventions to induce labour compared with placebo, no treatment or other interventions in women eligible for third-trimester induction. We included outcomes relating to efficacy, safety and acceptability to women. In addition, for the economic analysis we searched the Database of Abstracts of Reviews of Effects, and Economic Evaluations Databases, NHS Economic Evaluation Database and the Health Technology Assessment database. We carried out a network meta-analysis (NMA) using all of the available evidence, both direct and indirect, to produce estimates of the relative effects of each treatment compared with others in a network. We developed a de novo decision tree model to estimate the cost-effectiveness of various methods. The costs included were the intervention and other hospital costs incurred (price year 2012-13). We reviewed the literature to identify preference-based utilities for the health-related outcomes in the model. We calculated incremental cost-effectiveness ratios, expected costs, utilities and net benefit. We represent uncertainty in the optimal intervention using cost-effectiveness acceptability curves. RESULTS We identified 1190 studies; 611 were eligible for inclusion. The interventions most likely to achieve vaginal delivery (VD) within 24 hours were intravenous oxytocin with amniotomy [posterior rank 2; 95% credible intervals (CrIs) 1 to 9] and higher-dose (≥ 50 µg) vaginal misoprostol (rank 3; 95% CrI 1 to 6). Compared with placebo, several treatments reduced the odds of caesarean section, but we observed considerable uncertainty in treatment rankings. For uterine hyperstimulation, double-balloon catheter had the highest probability of being among the best three treatments, whereas vaginal misoprostol (≥ 50 µg) was most likely to increase the odds of excessive uterine activity. For other safety outcomes there were insufficient data or there was too much uncertainty to identify which treatments performed 'best'. Few studies collected information on women's views. Owing to incomplete reporting of the VD within 24 hours outcome, the cost-effectiveness analysis could compare only 20 interventions. The analysis suggested that most interventions have similar utility and differ mainly in cost. With a caveat of considerable uncertainty, titrated (low-dose) misoprostol solution and buccal/sublingual misoprostol had the highest likelihood of being cost-effective. LIMITATIONS There was considerable uncertainty in findings and there were insufficient data for some planned subgroup analyses. CONCLUSIONS Overall, misoprostol and oxytocin with amniotomy (for women with favourable cervix) is more successful than other agents in achieving VD within 24 hours. The ranking according to safety of different methods was less clear. The cost-effectiveness analysis suggested that titrated (low-dose) oral misoprostol solution resulted in the highest utility, whereas buccal/sublingual misoprostol had the lowest cost. There was a high degree of uncertainty as to the most cost-effective intervention. FUTURE WORK Future trials should be powered to detect a method that is more cost-effective than misoprostol solution and report outcomes included in this NMA.

Abstract
OBJECTIVE To evaluate the use of a transcervical Foley catheter plus oxytocin infusion compared with oxytocin infusion alone for labor induction and cervical ripening in women 34 weeks of gestation or greater with prelabor rupture of membranes. METHODS This is a randomized, multicenter trial of women with a live, singleton gestation at 34 weeks of gestation or greater with prelabor rupture of membranes, an unfavorable cervical examination (less than or equal to 2
cm dilated and less than or equal to 80% effaced), and no contraindication to labor. Participants were randomly allocated to a transcervical Foley catheter inflated to 30 cc with concurrent oxytocin infusion or oxytocin infusion alone. Oxytocin administration was standardized across sites. The primary study outcome was interval from induction to delivery. To detect a 2.5-hour difference in the interval from induction to delivery, we required outcome data on 194 women, assuming 80% power and a two-tailed α of 5%. Analysis was by intent to treat. RESULTS We enrolled 201 women: 93 were allocated to Foley and 108 to oxytocin. Demographics were similar between the groups. Time to delivery was not significantly different between groups: in the Foley group, it was 13.9 hours (±6.9 SD) compared with 14.4 hours (±7.9 SD) in the oxytocin group (P=.69). There were more cases of clinical chorioamnionitis (8% compared with 0%, P<.01) in the Foley group compared with the oxytocin group. There were no differences for other infectious morbidities or any other variable studied. CONCLUSION In patients with prelabor rupture of membranes, the use of a transcervical Foley catheter in addition to oxytocin does not shorten the time to delivery compared with oxytocin alone, but may increase the incidence of intraamniotic infection.

Abstract
Preterm delivery occurs in approximately 12% of all births in the United States and is a major factor that contributes to perinatal morbidity and mortality (1, 2). Preterm prelabor rupture of membranes (also referred to as premature rupture of membranes) (PROM) complicates approximately 3% of all pregnancies in the United States (3). The optimal approach to clinical assessment and treatment of women with term and preterm PROM remains controversial. Management hinges on knowledge of gestational age and evaluation of the relative risks of delivery versus the risks of expectant management (eg, infection, abruptio placentae, and umbilical cord accident). The purpose of this document is to review the current understanding of this condition and to provide management guidelines that have been validated by appropriately conducted outcome-based research when available. Additional guidelines on the basis of consensus and expert opinion also are presented.

Management of premature rupture of membranes at term: the need to correct a recurring mistake in articles, chapters, and recommendations of professional organizations. Am J Obstet Gynecol 2017; 217:661.e1-661.e3. [PMID: 28893527 DOI: 10.1016/j.ajog.2017.08.111] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2017] [Accepted: 08/31/2017] [Indexed: 11/21/2022]
Abstract
Recommendations about the management of premature rupture of membranes at term are based, in part, on a large, randomized controlled trial published in 1996: the TERMPROM trial. The original article contained an error in Table 1, in which "Interval from membrane rupture to delivery" was listed instead of "Interval from membrane rupture to study entry." While the authors and journal corrected this error, the mistake published in the original paper has made its way into subsequent publications and even in guidelines or practice bulletins issued by professional organizations, textbooks, and other publications around the world. The mistake, that half of women with premature rupture of membranes at term who were managed expectantly delivered within 5 hours and 95% delivered within 28 hours of membrane rupture, should be replaced with the actual fact that half of women with premature rupture of membranes at term who were managed expectantly delivered within 33 hours, and 95% delivered within 94-107 hours of membrane rupture. Correcting this error in contemporary health care information and publications is important to counsel patients accurately and to optimize the clinical care of women with premature rupture of membranes at term.

Abstract
Objective
The aim of this study was to assess the influence of premature rupture of membranes (PROM) on the induction of labor.
Material and Method
This historical cohort study analyzed 1861 inductions of labor at term using misoprostol which occurred between 2010 and 2015. Exclusion criteria included intrauterine fetal death, previous cesarean section, and fetal structural or chromosomal anomalies. Induction of labor for PROM (PROM group) was compared to induction for other indications (no-PROM group); the primary outcome measure was the cesarean section rate.
Results
The cesarean section rate for the PROM group was significantly lower (21.9% vs. 26.3%, p = 0.029). The induction-to-delivery interval was shorter (mean: 972 [854 – 6734] min vs. 1741 [97 – 10 834] min, p < 0.0001) and the rates of vaginal birth within 24 hours (80.9 vs. 52.0%, p = 0.0001) and 48 hours (98.4 vs. 85.3%, p = 0.0001) were higher in the PROM group. The impact of PROM on the cesarean section rate was not significant in multivariate analysis; however, PROM was found to have the greatest effect on the induction-to-delivery interval (p < 0.0001).
Conclusion
Premature rupture of membranes significantly affects various outcome measures when delivery is induced, particularly the induction-to-delivery interval.

Abstract
OBJECTIVE The objective of this study is to determine child health, development and educational outcomes for infants born following preterm prelabor rupture of the membrane (PPROM). STUDY DESIGN Population-based record linkage cohort study using data from NSW, Australia, 2001 to 2014. RESULTS Of 121 822 births at 20 to 37 weeks, 18 799 (15%) followed PPROM, 56 406 (46%) followed spontaneous labor and 46 617 (38%) were planned. Compared with infants of a similar gestational age born following spontaneous labor or planned delivery, exposure to PPROM did not increase the risk of childhood mortality, childhood hospitalization, developmentally vulnerable at school entry, low reading or numeracy scores. Median latency ranged from 12 days (interquartile range 3 to 37 days) at 25 weeks to 1 day (0 to 2 days) at 36 weeks. Longer latency and more advanced gestational age at birth were associated with better outcomes. CONCLUSION Infants born following PPROM are at no greater risk of adverse child health, development and education outcomes than those of similar gestational age born without PPROM.

Abstract
BACKGROUND In premature rupture of membranes (PROM), the risk of chorioamnionitis increases with increasing duration of membrane rupture. Decreasing the time from PROM to delivery is associated with lower rates of maternal infection. The American College of Obstetricians and Gynecologists suggests that all women with PROM who do not have a contraindication to vaginal delivery have their labor induced instead of being managed expectantly. Although the use of oxytocin for labor induction has been demonstrated to decrease the time to delivery compared with expectant management, no studies have evaluated the effectiveness of cervical ripening with a Foley bulb to additionally decrease the time to delivery. OBJECTIVE To determine whether simultaneous use of an intracervical Foley bulb and oxytocin decreases time from induction start to delivery in nulliparous patients with PROM compared with the use of oxytocin alone. STUDY DESIGN A randomized trial was conducted from August 2014 to February 2016 that compared the use of concurrent Foley bulb/oxytocin vs oxytocin alone in nulliparous patients ≥34 weeks' gestational undergoing labor induction for PROM. Our primary outcome was time from induction to delivery. Secondary outcomes were mode of delivery, tachysystole, chorioamnionitis, postpartum hemorrhage, Apgar scores, and admission to the neonatal intensive care unit. RESULTS A total of 128 women were randomized. Baseline characteristics were similar between groups. We found no difference in induction-to-delivery time between women induced with concurrent Foley bulb/oxytocin vs oxytocin alone (median time 13.0 hours [interquartile 10.7, 16.1] compared with 10.8 hours [interquartile range 7.8, 16.6], respectively, P = .09). There were no significant differences in mode of delivery, rates of postpartum hemorrhage, chorioamnionitis, or epidural use. Both groups had similar rates of tachysystole as well as total oxytocin dose. There were no differences in neonatal birth weight, Apgar scores, cord gases, or admissions to the neonatal intensive care unit. CONCLUSION This is the first randomized trial to compare concurrent Foley bulb/oxytocin vs oxytocin alone in nulliparous patients undergoing induction of labor for PROM. We found no difference in time from induction to delivery in patients induced with concurrent Foley bulb/oxytocin vs oxytocin alone. In nulliparous patients with PROM, this study suggests that addition of a Foley bulb to oxytocin does not decrease the time from induction start to delivery.

Abstract
AIMS To explore first-time mothers' expectations and experiences regarding rupture of membranes at term and their views on the potential use of reagent pads that detect amniotic fluid. BACKGROUND There is little information available on women's experiences of spontaneous rupture of membranes, or interest in using methods to confirm rupture of membranes (e.g. reagent pads). DESIGN Descriptive qualitative study, using focus groups and telephone interviews with women during pregnancy and after the birth of their first baby. Thematic analysis was undertaken to analyse women's responses. METHODS Ethics committee approval was obtained. Twenty-five women participated in the study of whom 13 contributed both during pregnancy and postpartum between October 2015-March 2016. FINDINGS Three overarching themes were identified from the data from women's expectations and experiences: uncertainty in how, when and where membranes may rupture; information which was felt to be limited and confirmation of rupture of membranes. The potential use of reagent pads met with varied responses. CONCLUSION Women were interested in having facts and figures regarding rupture of membranes, such as characteristics of liquor; volume and probability of membranes rupturing spontaneously at term. Use of a pad as a means of confirmation was viewed as helpful, although the potential for increasing anxiety was raised.

Abstract
OBJECTIVES To identify predictive criteria for a positive expectation in the context of rupture of membranes after 37 WG. METHODS Single-center retrospective study including ROM≥37 WG. The primary outcome was labour onset within 24hours. We compared predictive factors for occurrence of spontaneous labour and described obstetrical and neonatal outcomes according to initial Bishop score<6 or ≥6. RESULTS From January 2013 to December 2014, 520 patients were included. The predictive factors in case of unfavorable cervix were clinical leakage (P<0.001) and a cervical dilatation≥2cm (P<0.001) according to multivariate analysis. When the expectancy failed, there was a higher rate of cesarean section (24.3% vs. 9.6% P<0.001) but no more proven maternal-fetal infection. In case of Bishop≥6, we identified no predictive factor for labour onset but Apgar<7 at 5minutes (18.7% vs. 3.2% P=0.01) and admission to neonatal unit (18.8% vs. 3.2% P=0.04) were more frequent without majoration of maternal-fetal infection. CONCLUSION The favorable expectation was the outcome for 70.8% of ROM at term. Clinical leakage and dilated cervix appeared as the main predictors in case of Bishop<6. Majoration of low Apgar score and admission to neonatal unit could be increased when no labour onset occurred despite Bishop≥6.

Abstract
The aim of this retrospective study was to investigate the factors affecting the rates of caesarean section in cases with premature rupture of membranes (PROM) in term pregnancies. Eighty-two term PROM patients who presented to Turgut Ozal University and Erzurum Nene Hatun Hospitals between 2012 and 2014 were included. The effects of demographics, nulliparity, active-latent phase durations, presence of meconium and chorioamnionitis, requirement of oxytocin and cervical dilation at the initial examination on C/S rates were assessed. The C/S rates were changed with the duration of active period and the duration of latent period. It was found that the presence of cervical dilation at the initial examination significantly reduced the risk for progress to C/S at a rate of 87.5%. C/S rates did not change with other variables. We conclude that the factors increasing the risk for C/S in PROM at term group are not different from the non-term PROM. Impact statement The aim of this retrospective study was to investigate the factors affecting the rates of caesarean section (C/S) in cases with premature rupture of membranes (PROM) in term pregnancies. The C/S rates were changed with the duration of active period and the duration of latent period. It was found that the presence of cervical dilation at the initial examination significantly reduced the risk for progress to C/S at a rate of 87.5%. We conclude that the factors increasing the risk for C/S in PROM at term group, are not different from the non-term PROM groups. Currently, the PROM is considered the start of a pathological process in both term and preterm pregnancies and also considered to increase the rates of caesarean sections. Studies on the management of PROM at term have concentrated rather on whether to intervene for accelerating the labour or spontaneous monitorisation. As found by the studies like this one in the literature, the factors having an impact on C/S rates in the cases of PROM at term are similar to those of non-PROM patients at term, may prevent clinicians from taking an invasive or aggressive approach towards the cases of PROM at term.

Abstract
BACKGROUND Current management of preterm prelabour rupture of the membranes (PPROM) involves either initiating birth soon after PPROM or, alternatively, adopting a 'wait and see' approach (expectant management). It is unclear which strategy is most beneficial for mothers and their babies. This is an update of a Cochrane review published in 2010 (Buchanan 2010). OBJECTIVES To assess the effect of planned early birth versus expectant management for women with preterm prelabour rupture of the membranes between 24 and 37 weeks' gestation for fetal, infant and maternal well being. SEARCH METHODS We searched Cochrane Pregnancy and Childbirth's Trials Register (30 September 2016), and reference lists of retrieved studies. SELECTION CRITERIA Randomised controlled trials comparing planned early birth with expectant management for women with PPROM prior to 37 weeks' gestation. We excluded quasi-randomised trials. DATA COLLECTION AND ANALYSIS Two review authors independently evaluated trials for inclusion into the review and for methodological quality. Two review authors independently extracted data. We checked data for accuracy. We assessed the quality of evidence using the GRADE approach. MAIN RESULTS We included 12 trials in the review (3617 women and 3628 babies). For primary outcomes, we identified no clear differences between early birth and expectant management in neonatal sepsis (risk ratio (RR) 0.93, 95% confidence interval (CI) 0.66 to 1.30, 12 trials, 3628 babies, evidence graded moderate), or proven neonatal infection with positive blood culture (RR 1.24, 95% CI 0.70 to 2.21, seven trials, 2925 babies). However, early birth increased the incidence of respiratory distress syndrome (RDS) (RR 1.26, 95% CI 1.05 to 1.53, 12 trials, 3622 babies, evidence graded high). Early birth was also associated with an increased rate of caesarean section (RR 1.26, 95% CI 1.11 to 1.44, 12 trials, 3620 women, evidence graded high).Assessment of secondary perinatal outcomes showed no clear differences in overall perinatal mortality (RR 1.76, 95% CI 0.89 to 3.50, 11 trials, 3319 babies), or intrauterine deaths (RR 0.45, 95% CI 0.13 to 1.57, 11 trials, 3321 babies) when comparing early birth with expectant management. However, early birth was associated with a higher rate of neonatal death (RR 2.55, 95% CI 1.17 to 5.56, 11 trials, 3316 babies) and need for ventilation (RR 1.27, 95% CI 1.02 to 1.58, seven trials, 2895 babies, evidence graded high). Babies of women randomised to early birth were delivered at a gestational age lower than those randomised to expectant management (mean difference (MD) -0.48 weeks, 95% CI -0.57 to -0.39, eight trials, 3139 babies). Admission to neonatal intensive care was more likely for those babies randomised to early birth (RR 1.16, 95% CI 1.08 to 1.24, four trials, 2691 babies, evidence graded moderate).In assessing secondary maternal outcomes, we found that early birth was associated with a decreased rate of chorioamnionitis (RR 0.50, 95% CI 0.26 to 0.95, eight trials, 1358 women, evidence graded moderate), and an increased rate of endometritis (RR 1.61, 95% CI 1.00 to 2.59, seven trials, 2980 women). As expected due to the intervention, women randomised to early birth had a higher chance of having an induction of labour (RR 2.18, 95% CI 2.01 to 2.36, four trials, 2691 women). Women randomised to early birth had a decreased total length of hospitalisation (MD -1.75 days, 95% CI -2.45 to -1.05, six trials, 2848 women, evidence graded moderate).Subgroup analyses indicated improved maternal and infant outcomes in expectant management in pregnancies greater than 34 weeks' gestation, specifically relating to RDS and maternal infections. The use of prophylactic antibiotics were shown to be effective in reducing maternal infections in women randomised to expectant management.Overall, we assessed all 12 studies as being at low or unclear risk of bias. Some studies lacked an adequate description of methods and the risk of bias could only be assessed as unclear. In five of the studies there were one and/or two domains where the risk of bias was judged as high. GRADE profiling showed the quality of evidence across all critical outcomes to be moderate to high. AUTHORS' CONCLUSIONS With the addition of five randomised controlled trials (2927 women) to this updated review, we found no clinically important difference in the incidence of neonatal sepsis between women who birth immediately and those managed expectantly in PPROM prior to 37 weeks' gestation. Early planned birth was associated with an increase in the incidence of neonatal RDS, need for ventilation, neonatal mortality, endometritis, admission to neonatal intensive care, and the likelihood of birth by caesarean section, but a decreased incidence of chorioamnionitis. Women randomised to early birth also had an increased risk of labour induction, but a decreased length of hospital stay. Babies of women randomised to early birth were more likely to be born at a lower gestational age.In women with PPROM before 37 weeks' gestation with no contraindications to continuing the pregnancy, a policy of expectant management with careful monitoring was associated with better outcomes for the mother and baby.The direction of future research should be aimed at determining which groups of women with PPROM would not benefit from expectant management. This could be determined by analysing subgroups according to gestational age at presentation, corticosteroid usage, and abnormal vaginal microbiological colonisation. Research should also evaluate long-term neurodevelopmental outcomes of infants.

Abstract
Background. A 2013 Cochrane review concluded that the choice of antibiotics for prophylaxis in PROM is not clear. In Uganda, a combination of oral erythromycin and amoxicillin is the 1st line for prophylaxis against ascending infection. Our aim was to establish the current cervicovaginal bacteriology and antibiotic sensitivity patterns. Methods. Liquor was collected aseptically from the endocervical canal and pool in the posterior fornix of the vagina using a pipette. Aerobic cultures were performed on blood, chocolate, and MacConkey agar and incubated at 35-37°C for 24-48 hrs. Enrichment media were utilized to culture for GBS and facultative anaerobes. Isolates were identified using colonial morphology, gram staining, and biochemical analysis. Sensitivity testing was performed via Kirby-Bauer disk diffusion and dilution method. Pearson's chi-squared (χ2) test and the paired t-test were applied, at a P value of 0.05. Results. Thirty percent of the cultures were positive and over 90% were aerobic microorganisms. Resistance to erythromycin, ampicillin, cotrimoxazole, and ceftriaxone was 44%, 95%, 96%, and 24%, respectively. Rupture of membranes (>12 hrs), late preterm, and term PROM were associated with more positive cultures. Conclusion. The spectrum of bacteria associated with PROM has not changed, but resistance to erythromycin and ampicillin has increased.

Abstract
BACKGROUND Prelabour rupture of membranes (PROM) at term is managed expectantly or by planned early birth. It is not clear if waiting for birth to occur spontaneously is better than intervening, e.g. by inducing labour. OBJECTIVES The objective of this review is to assess the effects of planned early birth (immediate intervention or intervention within 24 hours) when compared with expectant management (no planned intervention within 24 hours) for women with term PROM on maternal, fetal and neonatal outcomes. SEARCH METHODS We searched Cochrane Pregnancy and Childbirth's Trials Register (9 September 2016) and reference lists of retrieved studies. SELECTION CRITERIA Randomised or quasi-randomised controlled trials of planned early birth compared with expectant management (either in hospital or at home) in women with PROM at 37 weeks' gestation or later. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trials for inclusion, extracted the data, and assessed risk of bias of the included studies. Data were checked for accuracy. MAIN RESULTS Twenty-three trials involving 8615 women and their babies were included in the update of this review. Ten trials assessed intravenous oxytocin; 12 trials assessed prostaglandins (six trials in the form of vaginal prostaglandin E2 and six as oral, sublingual or vaginal misoprostol); and one trial each assessed Caulophyllum and acupuncture. Overall, three trials were judged to be at low risk of bias, while the other 20 were at unclear or high risk of bias.Primary outcomes: women who had planned early birth were at a reduced risk of maternal infectious morbidity (chorioamnionitis and/or endometritis) than women who had expectant management following term prelabour rupture of membranes (average risk ratio (RR) 0.49; 95% confidence interval (CI) 0.33 to 0.72; eight trials, 6864 women; Tau² = 0.19; I² = 72%; low-quality evidence), and their neonates were less likely to have definite or probable early-onset neonatal sepsis (RR 0.73; 95% CI 0.58 to 0.92; 16 trials, 7314 infants;low-quality evidence). No clear differences between the planned early birth and expectant management groups were seen for the risk of caesarean section (average RR 0.84; 95% CI 0.69 to 1.04; 23 trials, 8576 women; Tau² = 0.10; I² = 55%; low-quality evidence); serious maternal morbidity or mortality (no events; three trials; 425 women; very low-quality evidence); definite early-onset neonatal sepsis (RR 0.57; 95% CI 0.24 to 1.33; six trials, 1303 infants; very low-quality evidence); or perinatal mortality (RR 0.47; 95% CI 0.13 to 1.66; eight trials, 6392 infants; moderate-quality evidence). SECONDARY OUTCOMES women who had a planned early birth were at a reduced risk of chorioamnionitis (average RR 0.55; 95% CI 0.37 to 0.82; eight trials, 6874 women; Tau² = 0.19; I² = 73%), and postpartum septicaemia (RR 0.26; 95% CI 0.07 to 0.96; three trials, 263 women), and their neonates were less likely to receive antibiotics (average RR 0.61; 95% CI 0.44 to 0.84; 10 trials, 6427 infants; Tau² = 0.06; I² = 32%). Women in the planned early birth group were more likely to have their labour induced (average RR 3.41; 95% CI 2.87 to 4.06; 12 trials, 6945 women; Tau² = 0.05; I² = 71%), had a shorter time from rupture of membranes to birth (mean difference (MD) -10.10 hours; 95% CI -12.15 to -8.06; nine trials, 1484 women; Tau² = 5.81; I² = 60%), and their neonates had lower birthweights (MD -79.25 g; 95% CI -124.96 to -33.55; five trials, 1043 infants). Women who had a planned early birth had a shorter length of hospitalisation (MD -0.79 days; 95% CI -1.20 to -0.38; two trials, 748 women; Tau² = 0.05; I² = 59%), and their neonates were less likely to be admitted to the neonatal special or intensive care unit (RR 0.75; 95% CI 0.66 to 0.85; eight trials, 6179 infants), and had a shorter duration of hospital (-11.00 hours; 95% CI -21.96 to -0.04; one trial, 182 infants) or special or intensive care unit stay (RR 0.72; 95% CI 0.61 to 0.85; four trials, 5691 infants). Women in the planned early birth group had more positive experiences compared with women in the expectant management group.No clear differences between groups were observed for endometritis; postpartum pyrexia; postpartum antibiotic usage; caesarean for fetal distress; operative vaginal birth; uterine rupture; epidural analgesia; postpartum haemorrhage; adverse effects; cord prolapse; stillbirth; neonatal mortality; pneumonia; Apgar score less than seven at five minutes; use of mechanical ventilation; or abnormality on cerebral ultrasound (no events).None of the trials reported on breastfeeding; postnatal depression; gestational age at birth; meningitis; respiratory distress syndrome; necrotising enterocolitis; neonatal encephalopathy; or disability at childhood follow-up.In subgroup analyses, there were no clear patterns of differential effects for method of induction, parity, use of maternal antibiotic prophylaxis, or digital vaginal examination. Results of the sensitivity analyses based on trial quality were consistent with those of the main analysis, except for definite or probable early-onset neonatal sepsis where no clear difference was observed. AUTHORS' CONCLUSIONS There is low quality evidence to suggest that planned early birth (with induction methods such as oxytocin or prostaglandins) reduces the risk of maternal infectious morbidity compared with expectant management for PROM at 37 weeks' gestation or later, without an apparent increased risk of caesarean section. Evidence was mainly downgraded due to the majority of studies contributing data having some serious design limitations, and for most outcomes estimates were imprecise.Although the 23 included trials in this review involved a large number of women and babies, the quality of the trials and evidence was not high overall, and there was limited reporting for a number of important outcomes. Thus further evidence assessing the benefits or harms of planned early birth compared with expectant management, considering maternal, fetal, neonatal and longer-term childhood outcomes, and the use of health services, would be valuable. Any future trials should be adequately designed and powered to evaluate the effects on short- and long-term outcomes. Standardisation of outcomes and their definitions, including for the assessment of maternal and neonatal infection, would be beneficial.

Abstract
PURPOSE To compare maternal and neonatal outcomes in induced vs. expectant management of term PROM. METHODS This retrospective study included patients with term PROM. A total of 325 were enrolled: 213 managed expectantly and 112 induced at admission and matched according to gestational age. Expectant management group patients were allowed to defer labour induction up to 48 h. Primary outcome measures were maternal or foetal signs of infection (chorioamnionitis, early neonatal sepsis or postpartum endometritis) and prolonged maternal hospitalization. Secondary outcome was caesarean delivery rate. RESULTS All group characteristics were comparable except that expectant management included more nulliparous women. Women managed expectantly had a higher rate of prolonged hospitalization [15 (7 %) vs. 2 (1.8 %); P = 0.043] as an indication of maternal complications, compared to induction management. They also had a higher rate of caesarean delivery [34 (16.4 %) vs. 8 (7.1 %), respectively; P = 0.024]. Adjustment for parity did not change the results. Early neonatal outcomes were similar between groups. CONCLUSIONS Expectant management increases the likelihood of caesarean delivery and prolonged maternal hospitalization. This should be considered when advising patients with term PROM regarding labour induction.

Abstract
Premature rupture of membranes (PROM) is a major factor that predisposes women to preterm delivery. Results from previous studies have suggested that there are associations between exposure to air pollution and preterm birth, but evidence of a relationship with PROM is sparse. Modified Community Multiscale Air Quality models were used to estimate mean exposures to particulate matter less than 10 µm or less than 2.5 µm in aerodynamic diameter, nitrogen oxides, carbon monoxide, sulfur dioxide, and ozone among 223,375 singleton deliveries in the Air Quality and Reproductive Health Study (2002-2008). We used log-linear models with generalized estimating equations to estimate adjusted relative risks and 95% confidence intervals for PROM per each interquartile-range increase in pollutants across the whole pregnancy, on the day of delivery, and 5 hours before delivery. Whole-pregnancy exposures to carbon monoxide and sulfur dioxide were associated with an increased risk of PROM (for carbon monoxide, relative risk (RR) = 1.09, 95% confidence interval (CI): 1.04, 1.14; for sulfur dioxide, RR = 1.15, 95% CI: 1.06, 1.25) but not preterm PROM. Ozone exposure increased the risk of PROM on the day of delivery (RR = 1.06, 95% CI: 1.02, 1.09) and 1 day prior (RR = 1.04, 95% CI: 1.01, 1.07). In the 5 hours preceding delivery, there were 3%-7% increases in risk associated with exposure to ozone and particulate matter less than 2.5 µm in aerodynamic diameter and inverse associations with exposure to carbon monoxide and nitrogen oxides. Acute and long-term air pollutant exposures merit further study in relation to PROM.

Abstract
AIM To evaluate the perinatal outcomes of newborns after premature rupture of membranes (PROM) at the term according to the timing of initial antibiotic administration. MATERIAL AND METHODS This is a retrospective, cohort study investigating perinatal outcomes of newborns in pregnant women with PROM at the term who were treated with ampicillin within or after 6 h from the PROM. Statistical analysis was performed using Student's t-test for continuous variables test and chi-square or for categorical data. RESULTS The study involved 144 pregnant women with PROM and their newborns, a lower number received antibiotics after birth were in the group who received antibiotics within 6 h of PROM (26.4% versus 73.6%), the mediane values of C-reactive protein were lower (3.0 ± 2.9 mg/l versus 6.1 ± 7.3 mg/l; p < 0.001), their newborns remained shorter in hospital after birth (4.13 versus 4.94; p =0.023) and time between PROM and delivery was shorter (p < 0.001). In group who received prophylactic antibiotics after 6 h of the PROM had significantly higher frequency of infection in newborns (45.3% versus 15.4%), and higher number of chorioamnionitis (9.72% versus 3,47%) compared to group who received antibiotics within 6h. CONCLUSION Timely usage of antibiotic prophylaxis and shorter time between PROM and delivery improve perinatal outcomes.

Abstract
BACKGROUND The risk of antepartum stillbirth at term is higher among women 35 years of age or older than among younger women. Labor induction may reduce the risk of stillbirth, but it also may increase the risk of cesarean delivery, which already is common in this older age group. METHODS We conducted a randomized, controlled trial involving primigravid women who were 35 years of age or older. Women were randomly assigned to labor induction between 39 weeks 0 days and 39 weeks 6 days of gestation or to expectant management (i.e., waiting until the spontaneous onset of labor or until the development of a medical problem that mandated induction). The primary outcome was cesarean delivery. The trial was not designed or powered to assess the effects of labor induction on stillbirth. RESULTS A total of 619 women underwent randomization. In an intention-to-treat analysis, there were no significant between-group differences in the percentage of women who underwent a cesarean section (98 of 304 women in the induction group [32%] and 103 of 314 women in the expectant-management group [33%]; relative risk, 0.99; 95% confidence interval [CI], 0.87 to 1.14) or in the percentage of women who had a vaginal delivery with the use of forceps or vacuum (115 of 304 women [38%] and 104 of 314 women [33%], respectively; relative risk, 1.30; 95% CI, 0.96 to 1.77). There were no maternal or infant deaths and no significant between-group differences in the women's experience of childbirth or in the frequency of adverse maternal or neonatal outcomes. CONCLUSIONS Among women of advanced maternal age, induction of labor at 39 weeks of gestation, as compared with expectant management, had no significant effect on the rate of cesarean section and no adverse short-term effects on maternal or neonatal outcomes.

Abstract
BACKGROUND Preterm pre-labour ruptured membranes close to term is associated with increased risk of neonatal infection, but immediate delivery is associated with risks of prematurity. The balance of risks is unclear. We aimed to establish whether immediate birth in singleton pregnancies with ruptured membranes close to term reduces neonatal infection without increasing other morbidity. METHODS The PPROMT trial was a multicentre randomised controlled trial done at 65 centres across 11 countries. Women aged over 16 years with singleton pregnancies and ruptured membranes before the onset of labour between 34 weeks and 36 weeks and 6 days weeks who had no signs of infection were included. Women were randomly assigned (1:1) by a computer-generated randomisation schedule with variable block sizes, stratified by centre, to immediate delivery or expectant management. The primary outcome was the incidence of neonatal sepsis. Secondary infant outcomes included a composite neonatal morbidity and mortality indicator (ie, sepsis, mechanical ventilation ≥24 h, stillbirth, or neonatal death); respiratory distress syndrome; any mechanical ventilation; and duration of stay in a neonatal intensive or special care unit. Secondary maternal outcomes included antepartum or intrapartum haemorrhage, intrapartum fever, postpartum treatment with antibiotics, and mode of delivery. Women and caregivers could not be masked, but those adjudicating on the primary outcome were masked to group allocation. Analyses were by intention to treat. This trial is registered with the International Clinical Trials Registry, number ISRCTN44485060. FINDINGS Between May 28, 2004, and June 30, 2013, 1839 women were recruited and randomly assigned: 924 to the immediate birth group and 915 to the expectant management group. One woman in the immediate birth group and three in the expectant group were excluded from the primary analyses. Neonatal sepsis occurred in 23 (2%) of 923 neonates whose mothers were assigned to immediate birth and 29 (3%) of 912 neonates of mothers assigned to expectant management (relative risk [RR] 0·8, 95% CI 0·5-1·3; p=0·37). The composite secondary outcome of neonatal morbidity and mortality occurred in 73 (8%) of 923 neonates of mothers assigned to immediate delivery and 61 (7%) of 911 neonates of mothers assigned to expectant management (RR 1·2, 95% CI 0·9-1·6; p=0·32). However, neonates born to mothers in the immediate delivery group had increased rates of respiratory distress (76 [8%] of 919 vs 47 [5%] of 910, RR 1·6, 95% CI 1·1-2·30; p=0·008) and any mechanical ventilation (114 [12%] of 923 vs 83 [9%] of 912, RR 1·4, 95% CI 1·0-1·8; p=0·02) and spent more time in intensive care (median 4·0 days [IQR 0·0-10·0] vs 2·0 days [0·0-7·0]; p<0·0001) compared with neonates born to mothers in the expectant management group. Compared with women assigned to the immediate delivery group, those assigned to the expectant management group had higher risks of antepartum or intrapartum haemorrhage (RR 0·6, 95% CI 0·4-0·9), intrapartum fever (0·4, 0·2-0·9), and use of postpartum antibiotics (0·8, 0·7-1·0), and longer hospital stay (p<0·0001), but a lower risk of caesarean delivery (RR 1·4, 95% CI 1·2-1·7). INTERPRETATION In the absence of overt signs of infection or fetal compromise, a policy of expectant management with appropriate surveillance of maternal and fetal wellbeing should be followed in pregnant women who present with ruptured membranes close to term.
