Abstract
INTRODUCTION Preterm premature rupture of membranes (PPROM) is the main cause of premature delivery, complicating 1-3% of all pregnancies. Conventional hospitalization (CH) is the most frequent mode of follow-up, but homecare (HC) seems to be an alternative. OBJECTIVES Study of the impact of the monitoring mode on the duration of the latency period and on the latency ratio after PPROM, and analysis of the risk factors modifying this ratio. METHODS This was a bicentric retrospective cohort study here-abouts including patients who presented a PPROM between 24 and 36weeks of gestation from 2016 to 2018. Patients had a follow-up in HC at Lille University Hospital center (UHC) and in CH at Nantes UHC according to two different follow-up protocols. The latency ratio corresponded to the real latency period divided by the latency period to theoretical term. RESULTS We included 154 patients: 102 in HC and 52 in CH. The mean latency period was significantly higher in HC: 36.9±21.8 days, corresponding to an 85.5±23.7% latency ratio versus 20.2±12 days, corresponding to an 66.9±29.8% latency ratio in CH (P<0.001). The latency ratio in CH was correlated with term at PPROM (P=0.001). CONCLUSIONS The duration of the latency period seems prolonged for PPROM followed by HC management versus CH in selected populations. This study suggests a benefit to HC in stable patients.

Abstract
Preterm premature rupture of membranes (PPROM) is one of the leading causes of perinatal morbidity and mortality. After a PPROM, more than 50% of pregnant women are delivered within 7 days. Fetal and maternal risks are primarily due to infection and inflammation, placental abruption, umbilical cord complications and preterm birth. Standard care usually consists of an expectant approach. Management includes the administration of antenatal steroids and antibiotic therapy. Patients with PPROM require close monitoring. The management of pregnant women with PPROM (inpatient vs. outpatient) is still the subject of controversial debate. The international guidelines also do not offer a clear stance. The statement presented here discusses the current state of knowledge.

Abstract
OBJECTIVE Preterm prelabor rupture of fetal membranes (pPROM) is a leading cause of preterm birth. When pPROM occurs around the pre- and periviable period, the perinatal outcome is unfavorable. However, there have been a few cases in which the leakage of amniotic fluid ceases and the ruptured fetal membranes are spontaneously sealed. MATERIALS AND METHODS The prognosis of 38 cases of pPROM at less than 27 weeks of gestation in Kyoto University Hospital were studied. The clinical factors related to the sealing of fetal membranes were investigated. RESULTS Spontaneous sealing was confirmed in five patients (13%), and sealing occurred within 14 days of pPROM. Women in the no sealing group delivered at 26.3 ± 0.5 weeks of gestation, whereas women in the sealing group delivered at term at 38.8 ± 0.4 weeks (p < 0.0001). The maximum vertical pocket (MVP) of amniotic fluid at the time of pPROM diagnosis was 2.2 ± 0.3 cm in the no sealing group and 3.8 ± 0.5 cm in the sealing group (p = 0.043). All cases of sealing occurred when the MVP at diagnosis was more than 2 cm, and there were no cases of sealing if the MVP at diagnosis was less than 2 cm. In addition, the value of C-reactive protein at ROM was less than 0.4 mg/dL in all cases in the sealing group. CONCLUSION The residual volume of sterile amniotic fluid at the onset of pPROM may predict the possibility of fetal membrane sealing.

Abstract
According to current guidelines, inpatient management until birth is considered standard in pregnant women with preterm premature rupture of membranes (PPROM). With the increasing burden on
obstetric departments and the growing importance of satisfaction and right to self-determination in pregnant women, outpatient management in PPROM is a possible alternative to inpatient
monitoring. The most important criterion for this approach is to ensure the safety of both the mother and the child. Due to the small number of cases (n = 116), two randomised controlled
trials (RCTs) comparing inpatient and outpatient management were unable to draw any conclusions. By 2020, eight retrospective comparative studies (cohort/observational studies) yielded the
following outcomes: no significant differences in the rate of maternal complications (e.g., chorioamnionitis, premature placental abruption, umbilical cord prolapse) and in neonatal
morbidity, significantly prolonged latency period with higher gestational age at birth, higher birth weight of neonates, and significantly shorter length of stay of preterm infants in
neonatal intensive care, shorter hospital stay of pregnant women, and lower treatment costs with outpatient management. Concerns regarding this approach are mainly related to unpredictable
complications with the need for rapid obstetric interventions, which cannot be performed in time in an outpatient setting. Prerequisites for outpatient management are the compliance of the
expectant mother, the adherence to strict selection criteria and the assurance of adequate monitoring at home. Future research should aim at more accurate risk assessment of obstetric
complications through studies with higher case numbers and standardisation of outpatient management under evidence-based criteria.

Abstract
OBJECTIVES The early identification of women with preterm premature rupture of membranes (p-PROM) who are at higher risk of imminent delivery remains challenging. The aim of our study was to evaluate if an increased echogenicity of the amniotic membranes may represent a sonographic marker of impending delivery in women with p-PROM. METHODS This was a prospective study including women with singleton pregnancies and diagnosis of p-PROM between 22 and 37 gestational weeks. A sonographic examination was performed within 24 h from the hospital admission and the appearance of the amniotic membranes close to the internal os was specifically evaluated. The membranes were defined as hyperechoic when their echogenicity was similar to that of the fetal bones or normoechoic in the other cases. The primary aim of the study was to compare the admission to spontaneous onset of labor interval and the pregnancy outcome between the cases of p-PROM with and without hyperechoic membranes. RESULTS Overall, 45 women fulfilled the inclusion criteria with similar characteristics at admission. In women with hyperechoic membranes, the admission to spontaneous onset of labor interval was significantly shorter (11.5 [5.3-25.0] vs. 3.0 [1.5-9.0] p=0.04) compared to women with normo-echoic membranes. At binomial logistic regression after adjustment for GA at hospital admission, the presence of hyperechoic membranes was found as the only independent predictor of spontaneous onset of labor ≤72 h (aOR: 6.1; 95% CI: 1.0-36.9). CONCLUSIONS The presence of hyperechoic membranes is associated with a 6-fold higher incidence of spontaneous onset of labor within 72 h independently from the gestational age at p-PROM.

Abstract
Background: While antenatal corticosteroids are routinely used to decrease adverse neonatal outcomes following preterm delivery, corticosteroids are also associated with worse outcomes in patients with viral respiratory infections. Currently in the setting of the COVID-19 pandemic, it is unclear whether antenatal corticosteroids for infant benefit outweigh the potential harm to a pregnant woman with a COVID-19 infection.Objective: To determine at which gestational ages administering antenatal corticosteroids is the optimal management strategy for hospitalized women with preterm prelabor rupture of membranes (PPROM) who have a COVID-19 infection.Methods: We designed a decision-analytic model to assess the maternal and infant outcomes associated with antenatal corticosteroid administration for risk of preterm delivery following rupture of membranes in the setting of a COVID-19 infection. We used a theoretical cohort of 10,000 women at each gestational age between 24 and 32 weeks who were hospitalized with PPROM and found to be COVID-19 positive. Maternal outcomes included intensive care unit admission and death related to COVID-19 infection. The infant outcomes of interest included respiratory distress syndrome, intraventricular hemorrhage, neurodevelopmental delay, and death, and were assessed along with maternal and infant quality-adjusted life years (QALYs). Deterministic and probabilistic sensitivity analyses were used to evaluate model assumptions.Results: In our theoretical cohort of 10,000 women with COVID-19 infection and preterm prelabor rupture of membrane between 24 and 32 weeks, corticosteroid administration resulted in 2,200 women admitted to the ICU and 110 maternal deaths at each gestational age. No antenatal corticosteroid use resulted in 1,500 ICU admissions and 75 maternal deaths at each gestational age. Antenatal corticosteroid administration also resulted in fewer cases of respiratory distress syndrome, intraventricular hemorrhage, and infant death. Overall, we found that between 24 and 30 weeks of gestation, administering antenatal corticosteroids was the optimal management strategy as it resulted in higher combined QALYs than no corticosteroid use. For 31 and 32 weeks of gestation, antenatal corticosteroid administration resulted in lower combined QALYs. On sensitivity analyses, we found that with increasing gestational age, the probability which antenatal corticosteroids was the optimal management strategy decreased.Conclusion: Administration of antenatal corticosteroids was an effective management strategy compared to no corticosteroid administration at gestational ages less than 31 weeks. These results provide data for clinicians to utilize when counseling pregnant patients hospitalized with PPROM and have a COVID-19 infection.

Abstract
OBJECTIVE Preterm pre-labour rupture of membranes (PPROM), one of the leading causes of preterm delivery, represents a serious economic and psychosocial health care burden. The unpredictability of the interval between PPROM and labour, also known as the latency period, can be unsettling for patients and clinicians alike. In singleton pregnancies, the literature supports the use of ultrasound-determined cervical length to estimate the latency period. METHODS With this retrospective cohort study, we sought to determine whether a shorter cervical length (≤25 vs. >25 mm) is associated with a shorter latency period in twin pregnancies complicated by PPROM. At McMaster University Medical Centre, a tertiary care centre, we used the Better Outcomes Registry Network (BoRN) database to identify patient records that met our criteria for inclusion over a 5-year period. RESULTS Forty-three records were included in our analysis. On average, shorter cervical length was statistically significantly associated with a 6-day shorter latency period (P = 0.035). Confounders were controlled for using ANCOVA statistical analysis. A moderate, positive correlation between cervical length and latency period was also identified (r = 0.4). CONCLUSION Understanding that a shorter cervical length is associated with a shorter latency period can assist clinicians in optimizing maternal counselling and patient care, including triaging transfers to tertiary care centres.

Abstract
BACKGROUND No intervention has proved effective to date in reducing the spontaneous preterm birth rate in twin pregnancies following an episode of threatened preterm labor and with a short cervix remaining. This study was designed to ascertain whether cervical pessaries are useful in preventing spontaneous preterm birth in women with twin pregnancies and a short cervix remaining after a threatened preterm labor episode. STUDY DESIGN This open, randomized, controlled trial was conducted in 132 pregnant women who had not delivered 48 hours after a threatened preterm labor episode and had a short cervix remaining (≤20 mm between 240 and 296 weeks and ≤10 mm between 300 and 336 weeks). Patients were randomly assigned to cervical pessary (n = 67) or routine management (n = 65). The primary outcome was the spontaneous preterm birth rate before 34 weeks. Spontaneous preterm birth before 28 and 37 weeks and neonatal morbidity and mortality were also evaluated in an intention-to-treat analysis. RESULTS Significant differences were observed in the spontaneous preterm birth rate before 34 weeks between the pessary and routine management groups (11 of 67 [16.4%] in the pessary group vs 21 of 65 [32.3%] in the control group; relative risk, 0.51 [confidence interval, 0.27-0.97]; P = .03). No significant differences were observed in the preterm birth rate < 28 weeks or < 37 weeks between groups. The pessary group less frequently required readmission for new threatened preterm labor episodes (4 of 67 [5.6%] vs 14 of 65 [21.5%]; relative risk, 0.28 [confidence interval, 0.10-0.80]; P = .009). Significant reduction was observed in the number of neonates weighing less than 2500 g (17.9% [24 of 134] vs 70.8% [92 of 130]; relative risk, 0.25 [confidence interval, 0.15-0.43]; P < .0001). CONCLUSION Pessary use did significantly lower the spontaneous preterm birth rate before 34 weeks in twin pregnancies with maternal short cervix remaining after a threatened preterm labor episode. Pessary use also reduced the threatened preterm labor recurrence and neonates' weight less than 2500 g.

Abstract
PURPOSE To characterize the parameters that predict preterm delivery in patients with preterm, premature rupture of membranes. METHODS This retrospective cohort study included women diagnosed with preterm premature rupture of membranes at 24-34 weeks gestation. Demographics, medical history, laboratory tests, and delivery data were reviewed. RESULTS Among 258 patients with preterm, premature rupture of membranes during the study period, 141 (54.7%) met the inclusion criteria. Therefore, the final cohort included 141 (54.78%) women, among whom, 32 (22.7%) delivered within the first 24 h of ROM and 109 (77.3%) delivered after 24 h. Univariant analysis revealed that advanced gestational age at the time of preterm, premature rupture of membranes, larger cervical dilation and leukocyte count at admission had significant effects on the likelihood of labor within 24 h. Analysis of the differences between each patient at admission to 24 h before labor in heart rate, temperature (fever), leukocyte counts and amniotic fluid color revealed significant changes in heart rate (P < 0.001), leukocyte count (P < 0.001) and in amniotic fluid from clean to meconium or bloody (P < 0.001). There was no significant change in elevated temperature (P = 0.065). CONCLUSIONS Our findings indicate that minimal changes in heart rate, body temperature (fever), leukocyte count and amniotic fluid color, within normal ranges, appear 24 h before delivery, among women with preterm, premature rupture of membranes and prolonged latency period. Increased attention to these changes might enable better follow-up and timing of delivery for patients with preterm, premature rupture of membranes before 34 weeks gestation.

Abstract
OBJECTIVE Prediction of delivery latency complicated with preterm premature rupture of membrane (PPROM) is crucial for reducing maternal and neonatal complications. Therefore, we investigated the correlations between latency period and cut-off values of ultrasonographic parameters, ultimately predicting delivery latency. MATERIALS AND METHODS The retrospective study was performed on 121 PPROM patients enrolled between March 2010 and July 2015. Parameters including amniotic fluid index (AFI), single deepest pocket (SDP) and transvaginal cervical length (TVCL) were measured in 99 singleton pregnancies with PPROM. Latency was defined as the period from sonographic measurements to delivery day. The parameters were analyzed independently by Wilcoxon rank sum test and Fisher's exact test. Cut-off values were determined using a receiver operating characteristic (ROC) curve. RESULTS In delivery latency within 3 days, AFI and SDP were decreased with significantly shorter TVCL. AFI and SDP had the highest sensitivity (82.2%) and SDP combined with TVCL showed the highest specificity (75.9%) in area under curve (AUC) value. The predicted median latency period was less than 2 days within the cutoff value of parameter (AFI ≤ 7.72, SDP ≤ 3.2 and TVCL ≤ 1.69). CONCLUSION AFI and SDP combined with TVCL could be useful predictive parameters of the latency interval from PPROM to delivery.

Abstract
OBJECTIVE To review the different parts of therapeutic management of viable preterm premature rupture of membranes (PPROM), except the antibiotherapy and birth modalities. METHODS The Medline, Cochrane Library, and Google Scholar databases over a period from 1980 to September 2018 have been consulted. RESULTS When the diagnostic of viable PPROM is reached, the woman should be hospitalized and signs of intrauterine infection (IUI) should be sought (Professional consensus). If cervical assessment appears necessary, speculum, digital examination or cervical ultrasound may be performed (Professional consensus). It is recommended to limit cervical evaluation regardless of the method used (Professional consensus). Initial ultrasound is recommended to determine the fetal presentation, locate the placenta, estimate the fetal weight and the residual amniotic fluid volume (Professional consensus). Performing vaginal and urinary bacteriological sampling at admission is recommended before any antibiotic (Professional consensus). In the case of positive vaginal culture, an antibiogram is necessary since it can guide antibiotherapy in the case of IUI and early onset neonatal bacterial sepsis (Professional consensus). In absence of demonstrated neonatal benefit, there is insufficient evidence to recommend or to not recommend initial tocolysis in PPROM (Grade C). If tocolysis was administered, it is recommended not to prolong it for more than 48hours (Grade C). Antenatal corticosteroid administration is recommended before 34 weeks of gestation (WG) (Grade A) and magnesium sulfate administration is recommended for women at high risk of imminent preterm birth before 32 WG (Grade A). Vitamin supplementation (vitamins C and E) is not recommended (Professional consensus), and it is recommended not to impose strict bed rest in case of PPROM (Professional consensus). In case of clinical signs of IUI with cerclage, it is recommended to remove the cerclage immediately (Professional consensus). The home care management of clinically stable PPROM after 48hours of hospital observation can be considered (Professional consensus). During the monitoring of a PPROM, it is recommended to identify elements relating to the diagnosis of IUI (Professional consensus). CONCLUSION The level of evidence and scientific data in the literature concerning the management (except antibiotics) of PPROM are low. Initial management of viable PPROM requires hospitalization. The main objectives of the management are the detection and medical care of maternal and fetal complications.

Abstract
INTRODUCTION Home care management offers a suitable alternative to hospitalization for management of preterm premature rupture of membranes (PPROM). Eligibility criteria have not been clearly established. Our aim was to determine predictive factors of complication during home care management of PPROM in order to define optimal eligibility criteria. MATERIAL AND METHODS Retrospective cohort study of all women with singleton pregnancies with PPROM managed as outpatients between 2009 and 2015. Complications were defined as the occurrence of one of these events: fetal death, placental abruption, umbilical cord prolapse, delivery outside maternity hospital, neonatal death. RESULTS In all, 187 women with PPROMs were managed as outpatients, of whom 12 had a complication (6.4%). In the "complication" group, gestational age at diagnosis (P = 0.006) and at delivery (P < 0.001) were lower, with no difference in latency between these two events. Three criteria significantly increased the risk for a severe complication: PPROM occurring before 26 weeks (P = 0.008), non-cephalic fetal presentation (P = 0.02) and oligoamnios (P = 0.02). When unfavorable criteria were associated with PPROM, the risk was increased (1 criterion, odds ratio [OR] 1.6; 2 criteria, OR 6.9 and 3 criteria, OR 32.8). CONCLUSIONS Combination of these three criteria is an indication for conventional hospitalization to limit maternal and fetal morbidity. When two criteria are combined, home care should be discussed for each case. If only one unfavorable criteria is present, outpatient management is suitable. To validate these results, a prospective randomized study should be conducted.

Abstract
Objective Cervical length measurement has been uggested as a useful tool for predicting intra-amniotic infection/inflammation in preterm labor, but little information is available in the setting of preterm premature rupture of membranes (pPROM). We aimed to determine whether a short cervical length is independently associated with an increased risk of intra-amniotic infection or inflammation and impending preterm delivery in women with pPROM. Methods This was a retrospective cohort study involving 171 consecutive singleton pregnant women with pPROM (21+0–33+6 weeks’ gestation), who underwent amniocentesis. Amniotic fluid (AF) was cultured, and assayed for interleukin (IL)-6 and IL-8. Cervical length was measured at the time of amniocentesis by transvaginal ultrasonography with an aseptic technique. Short cervical length was defined as a cervical length of ≤15 mm. Intra-amniotic infection was defined as a positive AF culture for microorganisms and intra-amniotic inflammation was defined as elevated AF concentrations of IL-6 or IL-8 (IL-6 ≥1.5 ng/mL and/or IL-8 ≥1.3 ng/mL). Results Fifty (29.2%) women had a sonographic cervical length of ≤15mm. On univariate analysis, short cervical length was associated with an increased risk for intra-amniotic infection and/or inflammation; no other parameters studied showed a significant association. Multivariable analyses indicated that short cervical length was significantly associated with a higher risk of impending preterm delivery (within 2 days of measurement, within 7 days of measurement, and before 34 weeks), and remained significant after adjustment for potential confounders. Conclusion In women with pPROM, short cervical length is associated with an increased risk for intra-amniotic infection/inflammation and associated with impending preterm delivery, independent of the presence of intra-amniotic infection/inflammation.

Abstract
Preterm birth remains a major cause of neonatal death and short and long-term disability in the US and across the world. The majority of preterm births are spontaneous and cervical length screening is one tool that can be utilized to identify women at increased risk who may be candidates for preventive interventions. The purpose of this document is to review the indications and rationale for CL screening to prevent preterm birth in various clinical scenarios. The Society for Maternal-Fetal Medicine recommends (1) routine transvaginal cervical length screening for women with singleton pregnancy and history of prior spontaneous preterm birth (grade 1A); (2) routine transvaginal cervical length screening not be performed for women with cervical cerclage, multiple gestation, preterm premature rupture of membranes, or placenta previa (grade 2B); (3) practitioners who decide to implement universal cervical length screening follow strict guidelines (grade 2B); (4) sonographers and/or practitioners receive specific training in the acquisition and interpretation of cervical imaging during pregnancy (grade 2B).

Abstract
AIM To evaluate the clinical usefulness of maternal serum interleukin-6 for the detection of subclinical chorioamnionitis and in the prediction of the latency period in patients with preterm premature rupture of membrane (PPROM). METHODS The study group included 60 patients at 24-34 weeks of gestation complaining of PPROM. Laboratory investigations included serial measurements of IL-6, TLC and CRP. Conservative management was carried out till 36 weeks unless delivery was indicated beforehand. The main outcome measures were the latency period and the occurrence of subclinical chorioamnionitis. RESULTS The mean gestational age at presentation was 30.9 weeks and 35.2 weeks at delivery. The mean IL-6 level at presentation was 4.7 pg/ml. There was no correlation between IL-6 at presentation and the latency period. In addition, those diagnosed as having subclinical chorioamnionitis by placental histopathology had significantly higher levels of IL-6 at delivery. Taking IL-6 level cutoff point of 8.5 pg/ml, histological chorioamnionitis, RDS and NICU admission were significantly higher above that level while neonatal birth weight, Apgar scores at one and five minutes were significantly lower. CONCLUSION Maternal serum IL-6 at the time of PPROM has no correlation to the latency period while IL-6 levels at the time of delivery have significant correlation to the subclinical chorioamnionitis and neonatal outcome measures.
