Abstract
OBJECTIVES The present study investigated the relationship between bronchopulmonary dysplasia (BPD) and intra-amniotic infection with Ureaplasma species. METHODS This was a single-center, retrospective cohort study. Patients with singleton pregnancies who underwent inpatient management at our department for preterm premature rupture of membranes (PPROM), preterm labor, cervical insufficiency, and asymptomatic cervical shortening at 22-33 gestational weeks were included. Amniocentesis was indicated for patients with PPROM or an elevated maternal C-reactive protein level (≥0.58 mg/dL). Patients with an amniotic fluid IL-6 concentration ≥3.0 ng/mL were diagnosed with intra-amniotic inflammation, while those with positive aerobic, anaerobic, M. hominis, and Ureaplasma spp. cultures were diagnosed with microbial invasion of the amniotic cavity (MIAC). Patients who tested positive for both intra-amniotic inflammation and MIAC were considered to have intra-amniotic infection. An umbilical vein blood IL-6 concentration >11.0 pg/mL indicated fetal inflammatory response syndrome (FIRS). The maternal inflammatory response (MIR) and fetal inflammatory response (FIR) were staged using the Amsterdam Placental Workshop Group Consensus Statement. RESULTS Intra-amniotic infection with Ureaplasma spp. was diagnosed in 37 patients, intra-amniotic infection without Ureaplasma spp. in 28, intra-amniotic inflammation without MIAC in 58, and preterm birth without MIR/FIR and FIRS in 86 as controls. Following an adjustment for gestational age at birth, the risk of BPD was increased in patients with intra-amniotic infection with Ureaplasma spp. (adjusted odds ratio: 10.5; 95% confidence interval: 1.55-71.2), but not in those with intra-amniotic infection without Ureaplasma spp. or intra-amniotic inflammation without MIAC. CONCLUSION BPD was only associated with intra-amniotic infection with Ureaplasma species.

Abstract
AIM This retrospective cohort study aimed to assess the utility of maternal C-reactive protein (CRP) and leukocyte levels in predicting neonatal sepsis after preterm premature rupture of membranes (pPROM). METHODS We conducted a retrospective cohort study (2009-2021), encompassing preterm infants born ≤29 + 6 weeks of gestation following pPROM. The primary outcome was early-onset neonatal sepsis within the initial 72 h of life. RESULTS We analysed data from 706 patients with a median gestational age at pPROM of 25.1 weeks and a median gestational age at birth of 26.4 weeks. Overall survival rate was 86.1%, with 65.7% survival without severe morbidities. These rates were significantly worse in preterm infants with sepsis. Maternal CRP and leukocyte levels correlated significantly with neonatal infection markers and sepsis. However, their predictive values, correlation coefficients, and area under the curve values were generally low. Using maternal CRP ≥2 mg/dL to predict neonatal sepsis yielded a positive predictive value of 18.5%, negative predictive value of 91.5%, AUC of 0.589, 45.5% sensitivity, and 74.5% specificity. CONCLUSION Maternal CRP and leukocyte levels were ineffective as a tool for predicting early-onset neonatal sepsis following early pPROM. Consequently, these biomarkers lack the reliability required for clinical decision-making in this context.

Abstract
OBJECTIVE Counseling of pregnancies complicated by pre- and periviable premature rupture of membranes to reach shared decision-making is challenging, and the current limited evidence hampers the robustness of the information provided. This study aimed to elucidate the rate of obstetrical and neonatal outcomes after expectant management for premature rupture of membranes occurring before or at the limit of viability. DATA SOURCES Medline, Embase, CINAHL, and Web of Science databases were searched electronically up to September 2023. STUDY ELIGIBILITY CRITERIA Our study included both prospective and retrospective studies of singleton pregnancies with premature rupture of membranes before and at the limit of viability (ie, occurring between 14 0/7 and 24 6/7 weeks of gestation). METHODS Quality assessment of the included studies was performed using the Newcastle-Ottawa Scale for cohort studies. Moreover, our study used meta-analyses of proportions to combine data and reported pooled proportions. Given the clinical heterogeneity, a random-effects model was used to compute the pooled data analyses. This study was registered with the International Prospective Register of Systematic Reviews database (registration number: CRD42022368029). RESULTS The pooled proportion of termination of pregnancy was 32.3%. After the exclusion of cases of termination of pregnancy, the rate of spontaneous miscarriage or fetal demise was 20.1%, whereas the rate of live birth was 65.9%. The mean gestational age at delivery among the live-born cases was 27.3 weeks, and the mean latency between premature rupture of membranes and delivery was 39.4 days. The pooled proportion of cesarean deliveries was 47.9% of the live-born cases. Oligohydramnios occurred in 47.1% of cases. Chorioamnionitis occurred in 33.4% of cases, endometritis in 7.0%, placental abruption in 9.2%, and postpartum hemorrhage in 5.3%. Hysterectomy was necessary in 1.2% of cases. Maternal sepsis occurred in 1.5% of cases, whereas no maternal death was reported in the included studies. When focusing on neonatal outcomes, the mean birthweight was 1022.8 g in live-born cases. The neonatal intensive care unit admission rate was 86.3%, respiratory distress syndrome was diagnosed in 66.5% of cases, pulmonary hypoplasia or dysplasia was diagnosed in 24.0% of cases, and persistent pulmonary hypertension was diagnosed in 40.9% of cases. Of the surviving neonates, the other neonatal complications included necrotizing enterocolitis in 11.1%, retinopathy of prematurity in 27.1%, and intraventricular hemorrhage in 17.5%. Neonatal sepsis occurred in 30.2% of cases, and the overall neonatal mortality was 23.9%. The long-term follow-up at 2 to 4 years was normal in 74.1% of the available cases. CONCLUSION Premature rupture of membranes before or at the limit of viability was associated with a great burden of both obstetrical and neonatal complications, with an impaired long-term follow-up at 2 to 4 years in almost 30% of cases, representing a clinical challenge for both counseling and management. Our data are useful when initially approaching such patients to offer the most comprehensive possible scenario on short- and long-term outcomes of this condition and to help parents in shared decision-making.

Abstract
Human fetal membranes (amniochorion) that line the intrauterine cavity consist of two distinct cell layers; single-layer amnion epithelial cells (AEC) and multilayer chorion trophoblast cells (CTC). These layers are connected through a collagen-rich extracellular matrix. Cellular remodeling helps support membrane growth and integrity during gestation and helps to maintain pregnancy. Preterm prelabor rupture of the human amniochorionic (fetal) membrane (pPROM) is antecedent to 40% of all spontaneous preterm birth. Oxidative stress (OS) induced activation of the p38 MAPK due to various maternal risk exposures and the amniochorion cells' senescence are reported pathological features of pPROM. Our transcriptomics analysis implicated dysregulated autophagy and epithelial-mesenchymal transition (EMT) in fetal membranes from pPROM. The molecular interplay between OS-induced p38 MAPK activation, autophagy, and EMT was investigated in AECs and CTCs to better understand the involvement of autophagy and EMT. We report the differential impact of OS on the autophagic machinery in AECs and CTCs, resulting in distinct cell fates. In AECs, OS-induced p38 MAPK activation causes autophagosome accumulation and reduced autophagic flux mediated by decreased ULK1 activity and kinase activity, leading to senescence. In CTCs, induction of autophagy has a limited effect; however, inhibition of autophagy led to SQSTM1-mediated EMT of trophoblast cells. Autophagy, EMT, and senescence were associated with proinflammatory changes. Thus, AECs and CTCs respond differently to OS via differential autophagy response, partly mediated via p38 MAPK. Besides senescence, OS-induced autophagy dysregulation in amniochorion cells may play a mechanistic role in pPROM pathophysiology.

Abstract
OBJECTIVE To compare the cardiac functions of fetuses with preterm premature rupture of membranes (PPROM) between their control groups and investigate its relationship with perinatal outcomes. METHODS This prospective study was conducted with 102 pregnant women. Pregnant women with PPROM were divided into two subgroups Group A, between 26 and 30 weeks, and Group B, between 30 and 34 weeks. A control group was formed by randomly including one healthy pregnant woman for each study patient. Sociodemographic, obstetric data, tissue Doppler imaging, and M-mode imaging results were compared. The relationship between echocardiographic parameters and perinatal outcomes was also investigated. RESULTS Tricuspid annular plane systolic excursion (TAPSE), S', and ET' of systolic cardiac parameters were shortened in both groups compared with their controls. Diastolic function indicator E'/A', and global function indicator myocardial performance index' increased in both groups. Isovolumetric contraction time' did not change between groups. A correlation was found between myocardial performance index', and the length of neonatal intensive care unit stay in Group A and TAPSE and duration of respiratory support and length of neonatal intensive care unit stay in Group B. CONCLUSIONS The fetal cardiac function seems to be affected by PPROM, and these changes are associated with neonatal outcomes. Therefore, administering fetal cardiac function evaluation in pregnancies complicated by PPROM may help physicians establish more appropriate clinical management protocols in this special population.

Abstract
OBJECTIVE This study aimed to investigate the roles of nuclear factor-kappa B p65 (NF-[Formula: see text]B p65) and tumor necrosis factor-α (TNF-α) in cell apoptosis occurring in the fetal membranes of pregnant women who experience preterm premature rupture of membranes (PPROM). METHODS This was a case-control study involving 57 pregnant women who delivered in the obstetric department of Affiliated Loudi Hospital, Hengyang Medical School, University of South China, from June 2021 to June 2022. Samples of fetal membrane tissue were collected from pregnant women with PPROM (n=27) and pregnant women who had normal deliveries (control group; n=30). The membrane tissue morphology of both groups was observed, and the expression of NF-[Formula: see text]B p65, p-NF-[Formula: see text]B p65, TNF-α, and caspase-3 was detected. Apoptosis in fetal membranes was examined. RESULTS Morphological evaluation of the fetal membrane tissues obtained from patients with PPROM revealed an abnormal structure with a thin collagen fiber layer and cells with a largely vacuolar cytoplasm. There was a positive correlation between the expression of p-NF-[Formula: see text]B p65/NF-[Formula: see text]B p65 and cell apoptosis (r1 =0.89, R2 =0.805, P=0.00). Furthermore, TNF-α was positively correlated with fetal membrane cell apoptosis (r2 =0.93, R2=0.881, P=0.00). CONCLUSION NF-[Formula: see text]B p65 is involved in the occurrence of PPROM by promoting the expression of TNF-α, which upregulates caspase-3 to cause apoptosis of fetal membrane cells.

Abstract
BACKGROUND Individuals hospitalized with preterm prelabor rupture of membranes are often advised to limit their activity or adhere to bed rest. Some evidence suggests that greater activity is associated with longer latency and improved outcomes, but no high-quality evidence from a randomized controlled trial exists. OBJECTIVE This study aimed to evaluate whether encouragement to ambulate at least 2000 steps daily affects latency among individuals with preterm prelabor rupture of membranes compared with usual care. STUDY DESIGN This was a multisite unblinded, 2-arm randomized trial of individuals at 23 0/7 to 35 0/7 weeks of gestation undergoing inpatient expectant management of preterm prelabor rupture of membranes with planned delivery at least 7 days away. Each participant wore a Fitbit Inspire that tracked steps. The intervention arm was encouraged (verbal and Fitbit-based reminders) to reach a goal of 2000 steps per day. The usual-care arm was allowed ad libitum activity with no step goal or reminders. The primary outcome was latency (days) from randomization to delivery. Secondary analyses included composite neonatal and maternal clinical outcomes and maternal mental health survey results. Statistical analyses were conducted with an intent-to-treat approach under a Bayesian framework using neutral priors (a priori assumed 50:50 likelihood of longer latency in either arm). A total of 100 participants were required to have 80% power to demonstrate a 4-day difference in latency with 75% certainty (Bayesian probability). RESULTS Among 163 eligible individuals, 100 (61%) were randomized, and after loss to follow-up, 95 were analyzed. Gestational age at randomization was 29 3/7 weeks (interquartile range, 26 2/7 to 31 5/7) in the intervention arm and 27 4/7 weeks (interquartile range, 25 4/7 to 29 6/7) in the usual-care arm. Median step counts were 1690 per day in the intervention arm (interquartile range, 1031-2641) and 1338 per day in the usual-care arm (interquartile range, 784-1913). Median days of latency were 9 days in the intervention arm (interquartile range, 4-17) and 6 days in the usual-care arm (interquartile range, 2-14). The primary analysis indicated a 65% posterior probability that the intervention increased latency relative to usual care (posterior relative risk, 1.09; 95% credible interval, 0.70-1.71). The relative risk was 0.55 (95% credible interval, 0.32-0.82) for the composite neonatal adverse outcome, with 99% posterior probability of intervention benefit, and was 0.94 (95% credible interval, 0.72-1.20) for the composite maternal adverse outcome, with 70% posterior probability of intervention benefit. There was a 94% posterior probability of the intervention arm having a greater decrease in maternal stress score from baseline to before delivery compared with the usual-care arm (mean arm difference, 3.24 points [95% credible interval, -7.23 to 0.79]). Adjustment for gestational age at randomization had minimal impact on secondary outcome results. CONCLUSION Individuals with preterm prelabor rupture of membranes randomized to encouragement to ambulate had a longer latency to delivery and improved neonatal and mental health outcomes, with similar maternal clinical outcomes compared with usual care.

Abstract
PROBLEM To assess the potential of five inflammatory and six angiogenic/antiangiogenic plasma proteins for predicting imminent spontaneous preterm delivery (SPTD; ≤14 days of sampling), microbial invasion of the amniotic cavity and/or intraamniotic inflammation (MIAC/IAI), and composite neonatal morbidity and mortality (CNMM) in women with early preterm premature rupture of membranes (PPROM). METHODS OF STUDY This retrospective cohort study included 76 singleton pregnant women with early PPROM (23-30 weeks). Amniotic fluid obtained via amniocentesis was cultured for microorganism detection and assayed for interleukin-6 to define IAI (≥2.6 ng/mL). Plasma C4a, endoglin, endostatin, IGFBP-1, IGFBP-2, MMP-9, PlGF, S100A8, S100A9, S100 A8/A9, and VEGFR-1 levels were determined using ELISA. RESULTS Multivariate logistic regression analyses revealed significant associations between (i) high levels of plasma S100A8/A9, SPTD ≤14 days after sampling, and shorter sampling-to-delivery intervals; (ii) elevated plasma MMP-9, S100A9, and S100A8/A9 levels and MIAC/IAI, and (iii) decreased plasma endoglin levels and increased CNMM risk, while adjusting for gestational age at sampling (or delivery) and tocolytic use. The area under the curves of the aforementioned proteins ranged from 0.655 to 0.731 for each outcome. Notably, the SPTD risk increased significantly with increasing plasma S100A8/A9 levels (P for trend < .05). CONCLUSIONS Plasma S100A8/A9, MMP-9, S100A9, and endoglin may represent valuable biomarkers associated with SPTD, MIAC/IAI, and CNMM in women with early PPROM. Owing to their less invasive nature, repeatability, and fair-to-moderate diagnostic accuracy, these biomarkers may contribute to risk stratification of PPROM-related complications in the clinical setting.

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 To analyze neonatal outcomes in very-low-birthweight (VLBW) infants depending on the presence of preterm premature rupture of membranes (PPROM), oligohydramnios, or both. METHODS The electronic medical records of VLBW infants admitted during the study period, January 2013 to September 2018, were reviewed. Neonatal outcomes (primary outcome: neonatal death; secondary outcome: neonatal morbidity) were compared depending on whether the infant was affected by PPROM or oligohydramnios. Logistic regression analysis was performed to assess the association of PPROM and oligohydramnios with neonatal outcomes. RESULTS Three hundred and nineteen VLBW infants were included: (1) 141 infants in the PPROM group vs. 178 infants in the non-PPROM group, and (2) 54 infants in the oligohydramnios group vs. 265 infants in the non-oligohydramnios group. The infants affected by PPROM were at significantly younger gestational ages at birth with lower 5-min Apgar scores than those not affected by PPROM. Histologic chorioamnionitis was significantly more frequent in the PPROM group than in the non-PPROM group. The proportions of small-for-gestational-age infants and infants affected by multiple births were significantly higher in the non-PPROM group. The median (interquartile range) PPROM latency and onset were 50.5 (9.0 - 103.0) h and 26.6 (24.1 - 28.5) weeks, respectively. Based on the logistic regression analysis assessing the association of PPROM and oligohydramnios with the significant neonatal outcome, oligohydramnios was significantly associated with neonatal death (odds ratio [OR] = 2.831, 95% confidence interval [CI] 1.447 - 5.539), air leak syndrome (OR = 2.692, 95% CI 1.224 - 5.921), and persistent pulmonary hypertension (PPH) (OR = 2.380, 95% CI 1.244 - 4.555). PPROM per se was not associated with any neonatal outcome. However, early onset PPROM and prolonged PPROM latency were associated with neonatal morbidity and mortality. When PPROM was accompanied by oligohydramnios, it was associated with increased odds for PPH (OR = 2.840, 95% CI 1.335 - 6.044), retinopathy of prematurity (OR = 3.308, 95% CI 1.325 - 8.259), and neonatal death (OR = 2.282, 95% CI 1.021 - 5.103). CONCLUSION PPROM and oligohydramnios affect neonatal outcomes differently. Oligohydramnios, but not PPROM, is a significant risk factor for adverse neonatal outcomes, which is presumably related to pulmonary hypoplasia. Prenatal inflammation appears to complicate neonatal outcomes in infants affected by early PPROM and prolonged PPROM latency.

Abstract
OBJECTIVE Intra-amniotic infections increase the risk of preterm delivery and short- and long-term fetal morbidity; however, no consensus exists on the choice of antimicrobial agents as treatment for these infections. We aimed to examine the efficacy of intravenous administration of sulbactam/ampicillin (SBT/ABPC) and azithromycin (AZM) for intra-amniotic infection in patients with preterm premature rupture of membranes (PPROM). METHODS This study followed a single-centered retrospective cohort design. We compared changes in interleukin 6 (IL-6) levels and the load of Ureaplasma species DNA in the amniotic fluid between singleton pregnancy patients with intra-amniotic infection (Group A) and without either intra-amniotic inflammation (IAI) or microbial invasion of the amniotic cavity (MIAC) (Group B) who developed PPROM between week 22, day 0 and week 33, day 6 of gestation and maintained pregnancy for ≥7 d after diagnosis (August 2014 to April 2020). Patients in Group A were treated with SBT/ABPC and AZM, whereas those in Group B were treated with ABPC and AZM or clarithromycin. RESULTS Thirty-one patients with IAI and 48 patients without either IAI or MIAC at diagnosis of PPROM underwent pregnancy/delivery management at our hospital. Following the study population selection, we evaluated six patients in Group A and 13 patients in Group B. Amniotic fluid IL-6 concentrations at the initial amniocentesis were high, ranging from 11.7 ng/mL to 139.2 ng/mL, indicating a state of severe IAI in all six patients in Group A. In five of the six patients in Group A, the amniotic fluid cultures during the first amniocentesis included Ureaplasma species only. In both groups, the amniotic fluid IL-6 concentration at the follow-up amniocentesis was lower than that at the initial amniocentesis (Group A: follow-up median 3.06 ng/mL [quartiles, 1.75-6.74], initial median 30.53 ng/mL [quartiles, 15.60-67.07], p=.03; Group B: follow-up median 0.40 ng/mL [quartiles, 0.18-0.69], initial median 0.96 ng/mL [quartiles, 0.65-1.42], p=.005); Group A showed a greater decrease than Group B (p < .001). No difference was found between the microbial loads of Ureaplasma species DNA in the initial and follow-up amniocentesis (p = .13). CONCLUSIONS In patients with PPROM and intra-amniotic infection, IL-6 levels in the amniotic fluid decreased significantly from before antimicrobial administration to day 7. This decrease is thought to be mainly due to the effects of intravenous AZM. The efficacy of AZM in patients with PPROM needs to be further confirmed via randomized controlled studies in the future.

Abstract
BACKGROUND Preterm delivery (PTD) includes three main presenting subtypes: spontaneous preterm labour (sPTL), preterm premature rupture of membranes (pPROM) and clinician-initiated preterm delivery (ciPTD). PTD subtype data are rarely available from birth registries and are onerous to derive from medical records. OBJECTIVES To develop and test the validity of a questionnaire to classify PTD subtype based on birthing parent recall of labour and delivery events. METHODS The questionnaire was sent in 2022 to 581 patients with PTD history documented in the LIFECODES study, a hospital-based birth cohort in Boston, Massachusetts. Eighty-two respondents reported 94 PTDs that could be linked to medical records. Data on PTD subtype were extracted from medical records as the reference standard. RESULTS Medical records indicated 47 spontaneous (24 sPTL, 23 pPROM) and 47 ciPTD deliveries occurring a median eight years earlier. The sensitivity and specificity of the recall questionnaire were 88% (95% confidence interval: 68, 97%) and 89% (79, 95%) for sPTL; 96% (78, 100%) and 94% (86, 98%) for pPROM; and 83% (69, 92%) and 100% (92, 100%) for ciPTD, respectively. Greater time since pregnancy did not degrade the sensitivity or specificity of the parental recall questionnaire. CONCLUSIONS Although derived from a modest sample, the moderate-to-high sensitivity and specificity of the parental recall questionnaire to classify sPTL, pPROM and ciPTD demonstrates its potential for large studies of PTD and for correction of misclassification bias. Future studies are required to test the questionnaire in a variety of populations.

Abstract
Preterm premature rupture of membranes (pPROM) is a major cause of preterm birth and neonatal mortality. Reactive oxygen species (ROS) have been identified as a critical factor in the development of pPROM. Mitochondria are known to be the primary source of ROS and play a vital role in maintaining cellular function. The Nuclear erythroid 2-related factor 2 (NRF2) has been demonstrated to play a crucial role in regulating mitochondrial function. However, research exploring the impact of NRF2-regulated mitochondria on pPROM is limited. Therefore, we collected fetal membrane tissues from pPROM and spontaneous preterm labor (sPTL) puerpera, measured the expression level of NRF2, and evaluated the degree of mitochondrial damage in both groups. In addition, we isolated human amniotic epithelial cells (hAECs) from the fetal membranes and used small interfering RNA (siRNA) to suppress NRF2 expression, enabling us to evaluate the impact of NRF2 on mitochondrial damage and ROS production. Our findings indicated that the expression level of NRF2 in pPROM fetal membranes was significantly lower than in sPTL fetal membranes, accompanied by increased mitochondrial damage. Furthermore, after the inhibition of NRF2 in hAECs, the degree of mitochondrial damage was significantly exacerbated, along with a marked increase in both cellular and mitochondrial ROS levels. The regulation of the mitochondrial metabolic process via NRF2 in fetal membranes has the potential to influence ROS production.

Abstract
BACKGROUND Not to delay delivery for more than 24 hours after rupture of the membrane is the thumb rule in obstetrics. Ascending infection from the vagina results in dangerous chorioamnionitis, which threatens the lives of the baby and mother. We developed a novel method to prevent ascending infection by using a vaginal drain, which helps to continue pregnancies if the leak stops and buys some time for antenatal steroids to act if the leak doesn't stop. METHOD In this study, 20 uncomplicated singleton pregnant women with spontaneous preterm premature rupture of membranes at gestational ages <35 weeks were recruited. Under the speculum, vaginal epithelial debris and secretions were cleared by a saline wash. The tip of the Nelaton Catheter was kept in the posterior fornix and then strapped to the thigh. The outer end was connected to the collection bag system and allowed to hang down to the ground. The foot end of the cot was raised. Leaked amniotic fluid and amniotic fluid index (AFI) were measured daily. A daily AFOD estimation was done for leaked AF. Uterine activity was controlled with low-dose Isoxsuprine Hydrochloride rapid infusion tocolysis. Antenatal steroids (ANS) were given. The spread of infection was monitored by maternal pulse rate, fetal heart rate, TC, and CRP. Pregnancies were terminated when leaks didn't stop, AFI didn't raise, or mature AFOD was observed. The number of women in whom leaks stopped, the number of days pregnancies continued, neonatal respiratory distress (NRD), birth weights, and perinatal deaths were recorded. Results: Leaks stopped in eight (40%) women. Pregnancy continuation ranged from 7 to 74 days. In 12 women, the leak did not stop, but we could buy 2-5 days' time for ANS to act. All parameters of the infection were within normal limits. Thirteen babies developed mild NRD, and we lost one baby. CONCLUSION By using a vaginal drain for P(P)ROM, ascending infection can be prevented, leaks can be stopped in 40% of women, and can buy time for ANS to act.

Abstract
OBJECTIVE Various prophylactic antibiotic regimens are used in the management of preterm premature rupture of membranes. We investigated the efficacy and safety of these regimens in terms of maternal and neonatal outcomes. DATA SOURCES We searched PubMed, Embase, and the Cochrane Central Register of Controlled Trials from inception to July 20, 2021. STUDY ELIGIBILITY CRITERIA We included randomized controlled trials involving pregnant women with preterm premature rupture of membranes before 37 weeks of gestation and a comparison of ≥2 of the following 10 antibiotic regimens: control/placebo, erythromycin, clindamycin, clindamycin plus gentamicin, penicillins, cephalosporins, co-amoxiclav, co-amoxiclav plus erythromycin, aminopenicillins plus macrolides, and cephalosporins plus macrolides. METHODS Two investigators independently extracted published data and assessed the risk of bias with a standard procedure following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Network meta-analysis was conducted using the random-effects model. RESULTS A total of 23 studies that recruited a total of 7671 pregnant women were included. Only penicillins (odds ratio, 0.46; 95% confidence interval, 0.27-0.77) had significantly superior effectiveness for maternal chorioamnionitis. Clindamycin plus gentamicin reduced the risk of clinical chorioamnionitis, with borderline significance (odds ratio, 0.16; 95% confidence interval, 0.03-1.00). By contrast, clindamycin alone increased the risk of maternal infection. For cesarean delivery, no significant differences were noted among these regimens. CONCLUSION Penicillins remain the recommended antibiotic regimen for reducing maternal clinical chorioamnionitis. The alternative regimen includes clindamycin plus gentamicin. Clindamycin should not be used alone.

Abstract
Background: Pancreatic stone protein (PSP) is a biochemical serum marker that contains levels that are elevated in various inflammatory and infectious diseases. The role of PSP in the diagnosis of these diseases seems to be more important compared to clinically established biochemical serum markers in discriminating the severity of the same diseases. Standard values for PSP in pregnant women in relation to gestational age have been reported recently. Additionally, increased PSP levels have been observed to be associated with renal dysfunction in pregnant women. The aim of this study is to evaluate the diagnostic role of PSP in pregnancy-related diseases, such as pre-eclampsia (PE), hemolysis-elevated liver enzymes, and low platelet (HELLP) syndrome. In addition, the study aims to assess its diagnostic role in inflammation-triggered diseases as preterm premature rupture of membranes (PPROM) or COVID-19-positive pregnant women. Materials and Methods: In this single-centred prospective study performed at a tertiary university hospital between 2013 and 2021, we included 152 pregnant women who were diagnosed with either PE, HELLP syndrome, or PPROM. In December 2020, in the context of the COVID-19 pandemic, the Independent Ethics Committee (IEC) approved an amendment to the study protocol. Depending on the underlying disease, single or serial-serum PSP measurements were assessed. These PSP values were compared to PSP levels of women with normal pregnancies. Results: Pregnant women diagnosed with pre-eclampsia or HELLP syndrome had significantly increased PSP values (mean 9.8 ng/mL, SD 2.6) compared to healthy singleton pregnant women (mean 7.9 ng/mL, SD 2.6, p ≤ 0.001). There was no difference in serum PSP in pregnant women with PPROM compared to women with uncomplicated singleton pregnancies (mean in PPROM: 7.9 ng/mL; SD 2.9 versus mean in healthy pregnancies: 7.9 ng/mL; SD 2.6, p = 0.98). Furthermore, no difference in the PSP values in women with or without intra-amniotic infection was observed (infection: mean 7.9 ng/mL; SD 2.8 versus no infection: mean 7.8 ng/mL; SD 3, p = 0.85). The mean value of PSP in COVID-19-infected women during pregnancy (8.5 ng/mL, SD 2.3) was comparable to healthy singleton pregnancies (mean 7.9 ng/mL, SD 2.6), p = 0.24. Conclusions: The novel serum biomarker PSP is significantly upregulated in pregnant women with pre-eclampsia and HELLP syndrome. Our observations call for the further evaluation of PSP in randomized controlled clinical trials to demonstrate the actual role of PSP in pregnancy-related diseases and whether it may provide new approaches for the management and discrimination of the severity of these gestational conditions.

Abstract
Objective To evaluate the relationship between maternal vascular malperfusion and acute intrauterine infection/inflammation with neonatal outcomes. Methods This was a retrospective study of women with singleton pregnancies who completed placenta pathological examination. The aim was to study the distribution of acute intrauterine infection/inflammation and maternal placental vascular malperfusion among groups with preterm birth and/or rupture of membranes. The relationship between two subtypes of placental pathology and neonatal gestational age, birth weight Z-score, neonatal respiratory distress syndrome, and intraventricular hemorrhage was further explored. Results 990 pregnant women were divided into four groups, including 651 term, 339 preterm, 113 women with premature rupture of membranes, and 79 with preterm premature rupture of membranes. The incidence of respiratory distress syndrome and intraventricular hemorrhage in four groups were (0.7%, 0.0%, 31.9%, 31.6%, P < 0.001) and (0.9%, 0.9%, 20.0%, 17.7%, P < 0.001), respectively. The incidence of maternal vascular malperfusion and acute intrauterine infection/inflammation were (82.0%, 77.0%, 75.8%, 72.1%, P = 0.06) and (21.9%, 26.5%, 23.1%, 44.3%, P = 0.010), respectively. Acute intrauterine infection/inflammation was associated with shorter gestational age (adjusted difference -4.7 weeks, P < 0.001) and decreased weight (adjusted Z score -2.6, P < 0.001) than those with no lesions in preterm birth. When two subtype placenta lesions co-occurrence, shorter gestational age (adjusted difference -3.0 weeks, P < 0.001) and decreased weight (adjusted Z score -1.8, P < 0.001) were observed in preterm. Consistent findings were observed in preterm births with or without premature rupture of membranes. In addition, acute infection/inflammation and maternal placenta malperfusion alone or in combination were associated with an increased risk of neonatal respiratory distress syndrome (adjusted odds ratio (aOR) 0.8, 1.5, 1.8), but the difference was not statistically significant. Conclusion Maternal vascular malperfusion and acute intrauterine infection/inflammation alone or co-occurrence are associated with adverse neonatal outcomes, which may provide new ideas for clinical diagnosis and treatment.

Abstract
BACKGROUND Preterm birth is the leading cause of infant morbidity and mortality worldwide. Elevated levels of oxidative stress have been associated with an increased risk of delivering before term. However, most studies testing this hypothesis have been conducted in racially and demographically homogenous study populations, which do not reflect the diversity within the United States. OBJECTIVE We leveraged 4 cohorts participating in the Environmental Influences on Child Health Outcomes Program to conduct the largest study to date examining biomarkers of oxidative stress and preterm birth (N=1916). Furthermore, we hypothesized that elevated oxidative stress would be associated with higher odds of preterm birth, particularly preterm birth of spontaneous origin. STUDY DESIGN This study was a pooled analysis and meta-analysis of 4 birth cohorts spanning multiple geographic regions in the mainland United States and Puerto Rico (208 preterm births and 1708 full-term births). Of note, 8-iso-prostaglandin-F2α, 2,3-dinor-5,6-dihydro-8-iso-prostaglandin-F2α (F2-IsoP-M; the major 8-iso-prostaglandin-F2α metabolite), and prostaglandin-F2α were measured in urine samples obtained during the second and third trimesters of pregnancy. Logistic regression was used to calculate adjusted odds ratios and 95% confidence intervals for the associations between averaged biomarker concentrations for each participant and all preterm births, spontaneous preterm births, nonspontaneous preterm births (births of medically indicated or unknown origin), and categories of preterm birth (early, moderate, and late). Individual oxidative stress biomarkers were examined in separate models. RESULTS Approximately 11% of our analytical sample was born before term. Relative to full-term births, an interquartile range increase in averaged concentrations of F2-IsoP-M was associated with higher odds of all preterm births (odds ratio, 1.29; 95% confidence interval, 1.11-1.51), with a stronger association observed for spontaneous preterm birth (odds ratio, 1.47; 95% confidence interval, 1.16-1.90). An interquartile range increase in averaged concentrations of 8-iso-prostaglandin-F2α was similarly associated with higher odds of all preterm births (odds ratio, 1.19; 95% confidence interval, 0.94-1.50). The results from our meta-analysis were similar to those from the pooled combined cohort analysis. CONCLUSION Here, oxidative stress, as measured by 8-iso-prostaglandin-F2α, F2-IsoP-M, and prostaglandin-F2α in urine, was associated with increased odds of preterm birth, particularly preterm birth of spontaneous origin and delivery before 34 completed weeks of gestation.

Abstract
AIM This study aimed to investigate maternal hematological laboratory parameters of pregnancies complicated with preterm premature rupture of membranes (PPROM) compared to mothers of healthy-term infants (control group). MATERIALS AND METHODS This case-control study included 158 mothers who were divided into PPROM (n=67) and control (n=91) groups, respectively. Laboratory parameters of platelet, lymphocyte, and neutrophil counts, neutrophil/lymphocyte ratio (NLR), and platelet/lymphocyte ratio (PLR) were recorded at the time of diagnosis for the PPROM group and at the time of hospital admission for birth for the control group. RESULTS NLR was significantly higher in the PPROM group than in the control group (p=0.001). The cutoff value of NLR to predict PPROM was 6.73 (AUC=0.671, 95% confidence interval=0.58-0.75, p=0.000). CONCLUSION A cheap and routine NLR blood test can be used to predict PPROM before labor.

Abstract
Preterm premature rupture of membranes, leading to preterm birth, is associated with neonatal and maternal morbidity and mortality. The study aimed to review the existing data on the best predictive value of pregnancy latency for known biomarkers in pregnancies after preterm premature rupture of membranes. The following databases were screened for the purposes of this systematic review: Pubmed/MEDLINE, Web of Science, EMBASE, Scopus, and the Cochrane Library. The study was conducted according to the PRISMA guidelines for systematic reviews. Only a few studies assessed biomarkers predicting pregnancy duration after PPROM. IL-6, IL-8, CRP, IL1RA, s-endoglin, βhCG, AFP, PCT, urea, creatinine, oxygen radical absorbance capacity, MDA, lipocalin-2, endotoxin activity, MMP-8, MMP-9 and S100 A8/A9 were found to have a positive predictive value for delivery timing prediction. Proinflammatory biomarkers, such as IL-6 or CRP, proved to be best correlated with delivery timing, independent of the occurrence of intrauterine infection.

Abstract
Objective To evaluate whether a rescue course of corticosteroids, when given at least 14 days after the initial course, is associated with an increased risk of neonatal sepsis after preterm premature rupture of membranes (PPROM). Methods We performed a retrospective, descriptive cohort study of women with singleton gestations from 23+0 to 34+0 weeks of gestation who received a rescue course of corticosteroids within the Indiana University Health Network from January 2009 through October 2016. Patients were separated into three groups based on amniotic membrane status at the time of each corticosteroid administration: Group 1 (intact membranes at initial/intact membranes at rescue), Group 2 (intact membranes at initial/PPROM at rescue), and Group 3 (PPROM at initial/PPROM at rescue). The primary outcome (neonatal sepsis) was compared between the groups. Patient characteristics and neonatal outcomes were analyzed with Fisher's exact test for categorical variables and ANOVA for continuous variables. Relative risk (RR) was calculated by comparing those with ruptured membranes to those with intact membranes at the time of rescue course administration. Results A total of 143 patients were eligible. Neonatal sepsis occurred in 6.8% of patients in Group 1, 21.1% of patients in Group 2, and 23.8% of patients in Group 3. Groups 2 and 3 had a statistically significant higher rate of neonatal sepsis than Group 1 (p = 0.021). The RR of neonatal sepsis after a rescue course in patients with PPROM (Groups 2 and 3) was 3.31 (95% CI = 1.32, 8.29) compared to those with intact membranes at the time of rescue course administration (Group 1). Conclusion A rescue course of corticosteroids in women with PPROM at the time of rescue administration was associated with an increased risk of neonatal sepsis. This increased risk was seen in women with intact membranes as well as ruptured membranes during their initial course of steroids. Larger studies are needed to further investigate this association.

Abstract
OBJECTIVES To investigate the adherence of German perinatal specialist units and those of basic obstetric care to the national guideline we compared data from a nation-wide survey on the practice of maintenance tocolysis, tocolysis in preterm premature rupture of membranes and in the perioperative setting of cervical cerclage, and bedrest during and after tocolysis with recommendations from the current German Guideline 015/025 "Prevention and Treatment of Preterm Birth". METHODS 632 obstetric clinics in Germany were approached and received a link to an online questionnaire. Data were descriptively analyzed by performing measures of frequency. To compare two or more groups Fisher's exact test was used. RESULTS The response rate was 19%; 23 (19.2%) of respondents did not perform maintenance tocolysis, while 97 (80.8%) conducted maintenance tocolysis; 30 (25.0%) of obstetric units performed cervical cerclage without tocolysis and 90 (75.0%) combined cervical cerclage with tocolysis; 11 (9.2%) of respondents did not use tocolytics in patients with preterm premature rupture of membranes, while 109 (90.8%) conducted tocolysis in these patients; 69 (57.5%) of obstetric units did not recommend bed rest during tocolysis, whereas 51 (42.5%) favored bedrest. Perinatal care centers of basic obstetric care recommend bed arrest during tocolysis statistically significant more often to their patients than those of higher perinatal care levels (53.6 vs. 32.8%, p=0.0269). CONCLUSIONS The results of our survey are in accordance to others from different countries and reveal considerable discrepancies between evidence-based guideline recommendations and daily clinical practice.

Abstract
PROBLEM To investigate whether altered expression of various inflammation-, angiogenesis-, and extracellular matrix-related mediators in cervicovaginal fluid (CVF) could be independently associated with acute histological chorioamnionitis (HCA), microbial-associated HCA, and funisitis in women with preterm premature rupture of membranes (PPROM). METHOD OF STUDY Clinical data of 102 consecutive singleton pregnant women with PPROM at 23+0 to 34+0 weeks were retrospectively analyzed. CVF samples were collected upon admission. Levels of APRIL, DKK-3, IGFBP-1/2, IL-6/8, lipocalin-2, M-CSF, MIP-1α, MMP-8/9, S100A8A9, TGFBI, TIMP-1, TNFR2, uPA, and VDBP were determined by ELISA. Placentas were histologically examined after birth. RESULTS Multivariate logistic regression analyses showed that: (1) elevated CVF levels of IL-8 and TNFR2 were independently associated with acute HCA; (2) elevated CVF levels of IL-6, IL-8, M-CSF, MMP-8, and TNFR2 were independently associated with microbial-associated HCA; and (3) elevated CVF IL-8 and MMP-8 levels were independently associated with funisitis when adjusted for gestational age. Areas under the curves of the aforementioned CVF biomarkers ranged within 0.61-0.77, thereby demonstrating poor to fair diagnostic capacity for these clinical endpoints. HCA risk significantly increased as the CVF levels of each inflammatory mediator increased (P for trend < 0.05). CONCLUSIONS Herein, we identified several inflammatory biomarkers (IL-6/8, M-CSF, MMP-8, and TNFR2) in the CVF that are independently associated with acute HCA, microbial-associated HCA, and funisitis in women with PPROM. Furthermore, the degree of inflammatory response in the CVF, based on the levels of these proteins, demonstrated a direct relationship with HCA risk (especially risk severity).

Abstract
PURPOSE The aim of this study was to evaluate the effect of gestational age (GA) at the time of fetoscopic laser photocoagulation (FLP) for severe twin-twin transfusion syndrome (TTTS) on perinatal outcomes in a single center in Taiwan. MATERIALS AND METHODS Severe TTTS was defined as a diagnosis of TTTS before a GA of 26 weeks. Consecutive cases of severe TTTS treated at our hospital with FLP between October 2005 and September 2022 were included. The evaluated perinatal outcomes were preterm premature rupture of membranes (PPROM) within 21 days of FLP, survival 28 days after delivery, GA at delivery, and neonatal brain sonographic imaging findings within 1 month of delivery. RESULTS We included 197 severe TTTS cases; the mean GA at the time of FLP was 20.6 weeks. After the cases were divided into cases of FLP at early (below 20 weeks) and late GAs (more than 20 weeks), the early-GA group was discovered to be associated with a deeper maximum vertical pocket in the recipient twin, a higher rate of PPROM development within 21 days of FLP, and lower rates of survival of one or both twins. In the cases of stage I TTTS, the rate of PPROM within 21 days of FLP was higher in the group that underwent FLP at an early GA than in the group that underwent FLP at a late GA (50% (3/6) vs. 0% (0/24), respectively, p = 0.005). Logistic regression analysis revealed that the GA at the time of FLP and the cervical length before FLP is implemented are significantly associated with the survival of one twin and the incidence of PPROM development within 21 days of FLP. The GA at the time of FLP, the cervical length before FLP, and TTTS being stage III TTTS were associated with the survival of both twins after FLP. Neonatal brain image anomalies were associated with GA at delivery. CONCLUSIONS FLP being performed at an earlier GA is a risk factor for lower fetal survival and PPROM development within 21 days of FLP in cases of severe TTTS. Delaying FLP for cases involving stage I TTTS diagnosed at an early GA without risk factors, such as maternal symptoms, cardiac overload in the recipient twin, or a short cervical length, may be considered, but whether delaying FLP would improve surgical outcomes and, if so, how long the delay should be may need further trials to answer.

Abstract
BACKGROUND Prophylactic antibiotic use in preterm premature rupture of membranes is associated with significantly reduced intra-amniotic infection and improved neonatal outcome, although data are insufficient to determine the optimal antibiotic regimen. Ampicillin resistance has changed the epidemiology of neonatal sepsis. OBJECTIVE This study aimed to determine the efficacy of two antibiotic regimens in prolonging the latency period in women with preterm premature rupture of membranes. STUDY DESIGN This randomized-controlled trial was conducted in 3 tertiary university-affiliated hospitals. A total of 124 women with preterm premature rupture of membranes at <37 weeks of gestation were randomized into two antibiotic prophylactic protocols: ampicillin + roxithromycin and cefuroxime + roxithromycin. The latency period length, neonatal adverse outcomes, and maternal infectious morbidity, including intrauterine infection, intrapartum fever, postpartum antibiotic treatment, endometritis, and wound infection, were measured and compared. RESULTS Maternal infectious morbidity was higher in the ampicillin group than in the cefuroxime group (17.7% vs 6.5%; 1-sided P value =.048). The pathogen distribution among placenta, membrane, cord, and uterine cultures differed between the groups (P=.017). Enterobacteriaceae spp. cultures were identified in 68.6% of the cultures in the ampicillin group and 43.2% in the cefuroxime group (P=.036). The composite neonatal adverse outcome was higher in the ampicillin group than in the cefuroxime group (55 [88.7%] vs 46 [74.2%]; 1-sided P value =.03). The proportion of primiparas with a latency period >4 days was significantly higher in the cefuroxime group than in the ampicillin group (odds ratio, 3.69; 95% confidence interval, 1.175-11.607; P=.025). CONCLUSION In combination with roxithromycin, the use of cefuroxime, as a prophylactic in women with premature rupture of membranes at <37 weeks of gestation, showed longer pregnancy in primiparas and less maternal and neonatal morbidity than the use of ampicillin. Further larger studies are needed to support our results.

Abstract
BACKGROUND Antibiotic treatment in preterm premature rupture of membranes can prolong the interval from membrane rupture to delivery and improve neonatal outcomes. However, the duration of antibiotic treatment for preterm premature rupture of membranes has been rarely compared in prospective studies. OBJECTIVE This study aimed to investigate the optimal duration of antibiotic treatment for premature rupture of membranes. We performed a randomized controlled trial comparing neonatal morbidity and infantile neurologic outcomes between 2 groups of patients with preterm premature rupture of membranes who received antibiotic treatment for 7 days or until delivery, respectively. STUDY DESIGN This prospective randomized study included patients who were diagnosed with preterm premature rupture of membranes between 22+0 weeks and 33+6 weeks of gestation. The enrolled patients were randomly assigned to receive intravenous cefazolin (1 g dosage every 12 hours) and oral clarithromycin (500 mg dosage every 12 hours) either for 7 days or until delivery. The study protocol was registered at ClinicalTrials.gov under identifier NCT01503606. The primary outcome was a neonatal composite morbidity, and the secondary outcome was neurologic outcomes at 12 months of corrected age. We enrolled 151 patients and allocated 75 and 76 of them to the 7-day and until-delivery groups, respectively. Analysis was done by per protocol. RESULTS After excluding cases lost to follow-up and those with protocol violations, 63 (7-day regimen) and 61 (until-delivery regimen) patients with preterm premature rupture of membranes and their babies were compared. There was no significant difference in the pregnancy outcomes, including gestational age at delivery and the interval from rupture of membranes to delivery, between the 2 groups. Among the neonatal outcomes, bronchopulmonary dysplasia, intraventricular hemorrhage, retinopathy of prematurity, necrotizing enterocolitis, and proven neonatal sepsis did not differ between the groups. However, the rates of respiratory distress syndrome (32.8% vs 50.8%; P=.039) and composite neonatal morbidities (34.4% vs 53.9%; P=.026) were lower in the until-delivery group than in the 7-day group. This difference remained statistically significant after a multivariable analysis adjusting for maternal age, twin pregnancy, antenatal corticosteroids treatment, gestational age at delivery, interval from rupture of membranes to delivery, and clinical chorioamnionitis. Infantile neurologic outcomes were evaluated in 71.4% of the babies discharged alive and did not differ between the groups. CONCLUSION Overall, the until-delivery regimen of cefazolin and clarithromycin in preterm premature rupture of membranes led to a lower incidence of composite neonatal morbidity and respiratory distress syndrome than the 7-day regimen, and both regimens otherwise showed similar individual neonatal morbidities and infantile neurologic outcomes.

Abstract
OBJECTIVE This study describes the fetal and neonatal outcomes and their predictive factors in pregnancies with preterm premature rupture of membranes (PPROM) before 24 weeks of gestation. METHODS A retrospective study was conducted using the patient database of a tertiary university hospital in Lyon, France. All of the medical data of women diagnosed with PPROM before 24 weeks of gestation from 2008 to 2018 were extracted. R software was used for descriptive and analytical statistics. RESULTS The study included 78 women. Mean gestational age (GA) at PPROM was 19.6 weeks (13.1 to 23.9 weeks). Fifteen (19.2%) pregnancies were terminated, 37 (47.4%) resulted in intrauterine fetal death (IUFD), and 26 (33.3%) children were born alive at an average of 26.9 weeks of gestation. Fourteen children survived and 12 died after birth; 50% of survivors had pulmonary hypoplasia. Within 7 days after PPROM, 46% of IUFD occurred and 36% of pregnancies ended. PPROM before 20 weeks of gestation and chorioamnionitis are statistically associated with IUFD, whereas a latency period of more than 2 weeks is statistically related to live birth. CONCLUSION PPROM before 24 weeks of gestation is associated with a high rate of IUFD, preterm birth, and postpartum mortality.

Abstract
OBJECTIVE To examine the outcomes and cost effectiveness of expectant management versus immediate delivery of women who experience preterm premature rupture of membranes (PPROM) at 34 weeks. METHODS A cost-effectiveness model was built using TreeAge software to compare outcomes in a theoretical cohort of 37,455 women with PPROM at 34 weeks undergoing expectant management until 37 weeks versus immediate delivery. Outcomes included fetal death, neonatal sepsis, neonatal death, neonatal neurodevelopmental delay, healthy neonate, maternal sepsis, maternal death, cost, and quality-adjusted life years. Probabilities were derived from the literature, and a cost-effectiveness threshold was set at $100,000 per quality-adjusted life year. RESULTS In our theoretical cohort of 37,455 women, expectant management yielded 58 fewer neonatal deaths and 164 fewer cases of neonatal neurodevelopmental delay. However, it resulted in 407 more cases of neonatal sepsis and 2.7 more cases of maternal sepsis. Expectant management resulted in 3,531 more quality-adjusted life years and a cost savings of $71.9 million per year, making it a dominant strategy. Univariate sensitivity analysis demonstrated expectant management was cost effective until the weekly cost of antepartum admission exceeded $17,536 (baseline estimate: $12,520) or the risk of maternal sepsis following intraamniotic infection exceeded 20%. CONCLUSION Our model demonstrated that expectant management of PPROM at 34 weeks yielded better outcomes on balance at a lower cost than immediate delivery. This analysis is important and timely in light of recent studies suggesting improved neonatal outcomes with expectant management. However, individual risks and preferences must be considered in making this clinical decision as expectant management may increase the risk of adverse perinatal outcomes when the risk of puerperal infection increases.

Abstract
Introduction: Fusobacterium nucleatum is a gram-negative anaerobe, a constituent of the oral microflora, responsible for chronic periodontal diseases. Case Report: We describe a preterm infant with premature rupture of membranes at 23 weeks of gestational age due to F. nucleatum. The newborn died soon after birth. Placental histopathology showed severe necrotizing chorioamnionitis and funisitis with gram-negative bacilli. After autopsy, F. nucleatum was microbiologically isolated from the lung. The mother had dental hygiene 1 day before delivery, presenting mild and diffuse gingivitis. At admission, she had leukocytosis, foul-smelling vaginal discharge, but no fever. Conclusion: This case highlights the possibility of F. nucleatum spreading from oral cavity after a dental procedure to the placenta with chorioamnionitis and fetal infection. This raises the question of whether dental procedures during pregnancy should be accompanied by prophylactic antibiotics.

Abstract
Objective: To investigate the severity of histologic chorioamnionitis /funisitis according to the indication for preterm delivery and their corresponding neonatal outcomes. Method: This study included 411 singleton women who delivered between 21+0 and 31+6 week of gestation due to preterm labor (PTL, n = 165), preterm premature rupture of membranes (PPROM, n = 202), or incompetent internal os of the cervix (IIOC, n = 44). The primary outcome measure was the rate of severe histological chorioamnionitis/funisitis. Secondary outcome measure was neonatal outcomes including neonatal and infant death, and neonatal composite morbidity. Results: The PPROM group demonstrated a higher rate of severe histological chorioamnionitis/funisitis compared to the PTL group (severe histological chorioamnionitis; PPROM, 66.3% vs. PTL, 49.1%, p = 0.001, severe funisitis; PPROM, 44.1% vs. PTL, 23.6%, p < 0.001) and this remained significant after multivariable analysis (severe histologic chorioamnionitis, OR 2.367, 95% CI 1.517−3.693; severe funisitis, OR 2.668, 95% CI 1.684−4.226). For neonatal outcomes only, a higher rate of patent ductus arteriosus was observed in the IIOC group compared to the PTL and PPROM groups (IIOC, 77.3% vs. PTL, 54.0% vs. PPROM, 54.0%, p = 0.043) and this remained significant after multivariable analysis. Conclusion: Indication of spontaneous preterm delivery might affect the placental inflammatory pathology and neonatal morbidity.

Abstract
PROBLEM To identify potential proteins in the amniotic fluid (AF) that may be associated with histologic chorioamnionitis (HCA) in patients with preterm premature rupture of membranes (PPROM) using antibody-based microarray analysis. METHOD OF STUDY This was a retrospective cohort study involving 100 singleton pregnant women with PPROM at 24-34 weeks who underwent amniocentesis and delivered within 120 h of amniocentesis. First, the AF proteomes of 15 patients with PPROM and HCA were compared with those of 15 gestational age-matched patients without HCA using a protein microarray. Next, 12 candidate proteins associated with HCA were further validated in 100 consecutive patients with PPROM by ELISA. RESULTS Of 507 proteins assessed in the microarray analysis, 46 showed significant intergroup differences. Further quantification confirmed that the levels of EN-RAGE, IL-6, MMP-9, TNFR2, SPARC, TSP2, and uPA were higher in the AF of PPROM patients with HCA than in those without. Multivariate analyses also showed that elevated AF EN-RAGE, IL-6, MMP-9, and TNFR2 levels were independently associated with HCA when adjusted for baseline variables. The frequency of the highest quartile of the aforementioned proteins significantly increased as the total grade of HCA increased; the risk of HCA significantly increased with increasing AF levels of each protein (P for trend < .001). CONCLUSIONS Using protein-antibody microarray technology, we discovered several potential AF proteins (EN-RAGE, IL-6, MMP-9, and TNFR2) independently associated with HCA in patients with PPROM. Furthermore, we demonstrated a direct correlation between the gradation of the intra-amniotic inflammatory response and HCA severity.

Abstract
PROBLEM We aimed to assess the predictive potential of 12 plasma biomarkers to predict acute histologic chorioamnionitis (HCA) in women with preterm premature rupture of membranes (PPROM) and to develop multi-biomarker panels based on these biomarkers in combination with widely used conventional laboratory markers. METHOD OF STUDY This was a retrospective cohort study involving 81 singleton pregnant women (24-34 weeks of gestation) who delivered within 96 h of blood sampling. White blood cell (WBC) count, differential counts, and C-reactive protein (CRP) levels were measured at admission. The levels of DKK-3, Fas, haptoglobin, IGFBP-2, kallistatin, MIP-1α, MMP-2, MMP-8, pentraxin 3, progranulin, E-selectin, and P-selectin were evaluated by ELISA using stored plasma samples. The primary outcome measure was acute HCA. RESULTS Multivariate analyses showed that low plasma E-selectin and kallistatin levels were independently associated with HCA occurrence after adjusting for gestational age. Using a stepwise regression analysis, a multi-biomarker panel comprising plasma E-selectin, serum CRP, and WBC was developed, which provided a good prediction of acute HCA in women with PPROM (area under the curve [AUC], 0.899), with a significantly higher AUC than that of any single variable included in the panel (P<0.05). The plasma levels of DKK-3, Fas, haptoglobin, IGFBP-2, MIP-1α, MMP-2, MMP-8, pentraxin 3, and P-selectin were not significantly associated with HCA occurrence. CONCLUSIONS This study identified E-selectin and kallistatin as potential plasma biomarkers associated with acute HCA in women with PPROM. Their combined analysis with serum CRP and WBC counts significantly improved acute HCA diagnosis. This article is protected by copyright. All rights reserved.

Abstract
AIM To evaluate whether there is a stepwise increase in the prevalence of maternal clinical signs according to the severity of histological inflammation in the chorioamniotic membranes, placenta, and umbilical cord in preterm deliveries. METHODS This retrospective study, conducted between January 2007 and May 2017, included patients with preterm delivery between 22 and 33 weeks. The histological findings of maternal/fetal inflammatory responses were staged and graded according to the Amsterdam Placental Workshop Group consensus statement. Correlations between the histological severity of maternal/fetal inflammatory responses and the prevalence of clinical chorioamnionitis and clinical signs were evaluated using the Cochran-Armitage trend test. RESULTS A total of 138 patients were included. The stage and grade of the maternal inflammatory response were correlated with earlier gestational weeks at delivery and lighter birth weight. The prevalence of clinical chorioamnionitis was significantly correlated with a higher stage and grade of the maternal inflammatory response (Gibbs/Lencki criteria: 15.8%/15.8% in Stage 3, 16.3%/14% in Grade 2). No significant correlations were observed between gestational weeks at delivery and birth weight and stage/grade of fetal inflammatory response. The prevalence of clinical chorioamnionitis was significantly correlated with higher stage and grade of fetal inflammatory response (Gibbs/Lencki criteria: 25%/25% in Stage 3 and 29.4%/29.4% in Grade 2). CONCLUSION Correlations exist between the severity of histological maternal/fetal inflammatory responses and the prevalence of clinical chorioamnionitis and positive maternal clinical signs in preterm deliveries. However, the prevalence of clinical chorioamnionitis was 20%-30% even in the most severe fetal inflammatory responses.

Abstract
Preterm premature rupture of membranes (PPROM) interrupts normal lung development, resulting in neonatal respiratory morbidity. Although post-PPROM risks have been researched, only a few studies have investigated noninvasively obtained amniotic fluid (AF) to predict neonatal outcomes. In this study, we aimed to determine whether epidermal growth factor (EGF) in vaginally-collected AF is a significant predictor of neonatal respiratory outcomes after PPROM. We analyzed EGF in vaginally-obtained AF from 145 women with PPROM at 22−34 weeks of gestation. The following neonatal outcomes were included: respiratory distress syndrome, surfactant need, duration and type of respiratory support, and bronchopulmonary dysplasia. We found that EGF concentration was associated with gestational age, and its medians were lower in neonates with respiratory morbidities than unaffected ones. EGF concentrations gradually declined, the lowest being in the most clinically ill patients. EGF < 35 pg/mL significantly predicted the odds of severe respiratory outcomes. EGF in noninvasively collected AF may be a reliable predictor for respiratory outcomes of preterm neonates with PPROM before 34 weeks of gestation. The results of our study may have implications for further research both in noninvasive amniotic fluid analysis and the management of patients after PPROM.

Abstract
OBJECTIVES Preterm premature rupture of membranes (PPROM) remote from term is an important obstetric cause of maternal and fetal adverse outcomes. The aim of our study is to examine the efficacy of ampicillin and Lactobacillus casei rhamnosus treatment in cases of PPROM remote from term. MATERIAL AND METHODS The study was carried out by examining the results of cases who were given Ampicillin and Lactobacillus casei rhamnosus treatment. The patients were divided into two groups. Group 1 who didn't develop clinical chorioamnionitis and Group 2 who developed clinical chorioamnionitis. Obstetric characteristics, neonatal outcomes, adverse events were recorded. RESULTS A total of 46 pregnant women, 40 in Group 1 and six in Group 2, were included in the study. The frequency of clinical chorioamnionitis developing during the treatment was found to be 13.0%. Mean gestational age at diagnosis was 28.43 ± 2.38 and 28.17 ± 1.33 for Groups 1 and Group 2, respectively. Mean gestational age at the time of delivery was 32.38 ± 2.07 31.33 ± 1.63 for Group 1 and Group 2, respectively. The mean latency period for Group 1 and Group 2 was 27.45 ± 1.71 days, 23.66 ± 4.53, respectively. Sepsis developed in six newborns (15%) in Group 1, while it developed in three newborns (50%) in Group 2. While 90% of the babies in Group 1 were discharged from the hospital, this rate was 66.7% in Group 2. CONCLUSIONS Ampicillin + Lactobacillus casei rhamnosus is an effective treatment method in PPROM cases and positively affects perinatal outcomes.

Abstract
OBJECTIVES To investigate association between latency after preterm premature rupture of membranes (PPROM) and perinatal outcomes at moderately and late preterm gestation. METHODS National perinatal registry-based cohort study using data for the period 2013-2018. Singleton pregnancies with non-malformed fetuses in cephalic presentation complicated by PPROM at 32+0-36+6 weeks were included. Associations between latency period and perinatal mortality, neonatal respiratory distress syndrome (RDS), early onset neonatal infection (EONI), and cesarean section were assessed using multiple logistic regression, adjusting for potential confounders (labor induction, maternal body-mass-index, maternal age, antenatal corticosteroids, and small-for-gestational-age). p<0.05 was considered statistically significant. RESULTS Of 3,017 pregnancies included, 365 (12.1%) had PPROM at 32+0-33+6 weeks and 2,652 (87.9%) at 34+0-36+6 weeks. Among all cases, 2,540 (84%) had latency <24 h (group A), 305 (10%) 24-47 h (group B), and 172 (6%) ≥48 h (group C). Longer latency was associated with higher incidence of EONI (adjusted odds ratio [aOR] 1.350; 95% confidence interval [CI] 0.900-2.026 for group B and aOR 2.500; 95% CI 1.599-3.911 for group C) and higher rate of caesarean section (aOR 2.465; 95% CI 1.763-3.447 for group B and aOR 1.854; 95% CI 1.172-2.932 for group C). Longer latency was not associated with rates of RDS (aOR 1.160; 95% CI 0.670-2.007 for group B and aOR 0.917; 95% CI 0.428-1.966 for group C). CONCLUSIONS In moderately to late PPROM, increased latency is associated with higher risk of EONI and cesarean section with no reduction in RDS.

Abstract
BACKGROUND Culture-proven sepsis is the gold standard in early-onset neonatal sepsis diagnosis. Infants born ≤29 weeks gestation after preterm rupture of membranes in the years 2009-2015 were included in a retrospective cohort study performed at a level III fetal-maternal unit. The study aimed to compare culture-proven sepsis, clinical sepsis and positive laboratory biomarkers ≤72 h as predictors of mortality before discharge and the combined outcome of mortality or severe short-term morbidity (severe cerebral morbidity, bronchopulmonary dysplasia and retinopathy). RESULTS Of the 354 patients included, culture-proven sepsis, clinical sepsis and laboratory biomarkers were positive in 2.3%, 8.5% and 9.6%, respectively. The mortality rate was 37.5% for patients with culture-proven sepsis (3/8), 33.3% for patients with clinical sepsis (10/30) and 8.8% for patients with positive laboratory biomarkers (3/34), respectively. Mortality or severe morbidity occurred in 75.0% of patients with culture-proven sepsis (6/8), 80.0% of patients with clinical sepsis (24/30) and 44.1% of patients with positive laboratory biomarkers (15/34), respectively. CONCLUSION In preterm infants after preterm rupture of membranes, clinical sepsis was almost four times more common and at least equally valuable in predicting mortality and mortality or severe morbidity compared to culture-proven sepsis.

Abstract
The impact of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) in pregnancy has yet to be determined. Some studies indicate that SARSCoV- 2 infection may be associated with a higher risk of adverse outcomes in pregnant women. Here, we performed a meta-analysis to estimate the frequency of intrauterine growth restriction (IUGR) and preterm premature rupture of the membranes (PPROM) in pregnant women with Coronavirus disease-2019 (COVID-19). A comprehensive search was performed in various databases, such as PubMed, Scopus, SciELO, MedRxiv, and Web of Science, to find all relevant studies published before 10 February 2021. Cross-sectional and consecutive case series reporting the pregnancy outcomes of COVID-19 were included. A total of 24 studies, including 8 studies on IUGR and 16 studies on PPROM, were selected. Pooled data showed that the frequencies of IUGR and PPROM in pregnant women with COVID-19 were 2.6% and 9.9%, respectively. Analyses stratified by ethnicity showed that the frequencies of IUGR in Asian and Caucasian COVID-19-infected pregnant women were 2.9% and 2.0%, respectively. Moreover, the frequencies of PPROM in Asian and Caucasian COVID-19-infected pregnant women were 10.2% and 5.8%, respectively. This meta-analysis showed that the frequencies of IUGR and PPROM in COVID-19-infected pregnant women were 2.6% and 9.9%, respectively. However, well-designed, large-scale and multicenter clinical studies are required to improve and validate these results.

Abstract
Background The neutrophil-lymphocyte ratio (NLR) is easily calculated blood test parameter, which can be used as marker to predict many inflammatory disorders. The aim of this study was to assess and compare the NLR in maternal blood with the white blood cell (WBC) count and C-reactive protein (CRP) concentration for the prediction of histological chorioamnionitis. Methods This was a case-control study of 137 woman with preterm premature rupture of membranes (PPROM) at a gestational age between 22+ 0 and 34+ 6 weeks. Blood samples, collected less than 48 h before delivery and at least 48 h after the administration of corticosteroids, were selected for the analysis. The NLR was calculated by dividing the number of neutrophils by the number of lymphocytes. Chorioamnionitis was diagnosed by the histopathological evaluation of placental membranes and chorionic plate. Results Patients with diagnosed histological chorioamnionitis (HCA) had significantly higher levels of WBC, CRP and NLR (p-value < 0.001). Levels of WBC, CRP and NLR predicted HCA with an area under the curve (AUC) of 0.81, 0.81 and 0.89, respectively. NLR had statistically significantly higher AUC than WBC, but no significant difference was found between AUCs of NLR and CRP. The cut-off level of NLR was found to be 5,97, which had a sensitivity of 77 % and a specificity of 95 %. Conclusion NLR has a good predictive value for HCA and could be used as an additional diagnostic marker for predicting histological chorioamnionitis in cases with preterm premature rupture of membranes before 34 weeks of gestation.

Abstract
INTRODUCTION This study was conducted to evaluate soluble Toll-like receptor 2 (sTLR-2) and soluble Toll-like receptor 4 (sTLR-4) levels in vaginally obtained amniotic fluid and investigate their value in the prediction of histological chorioamnionitis (HCA). MATERIAL AND METHODS This prospective case-control study included patients who had been diagnosed with preterm premature rupture of membranes before 34 weeks of gestation and were admitted to Vilnius University Hospital Santaros Klinikos. Free leaking amniotic fluid was obtained vaginally using a sterile speculum up to 48 h before delivery. Amniotic fluid levels of sTLR-2 and sTLR-4 were determined using an enzyme-linked immunosorbent assay. The diagnosis of chorioamnionitis was confirmed by histological examination of the placenta and membranes after delivery. RESULTS The study included 156 patients, 65 with (HCA Group) and 91 without (non-HCA Group) HCA. No statistically significant differences were noted in the concentrations of sTLR-2 and sTLR-4 in vaginally obtained amniotic fluid between patients with and without HCA: the median sTLR-2 level was 0.09 ng/mL in the HCA Group vs 0.1 ng/mL in non-HCA Group, and the median sTLR-4 level was 0.23 ng/mL in the HCA Group vs 0.28 ng/mL in non-HCA Group (p > 0.05). A positive correlation between sTLR-2 and sTLR-4 levels was identified (ρ = 0.57, p < 0.001), but no correlation was found between these markers and gestational age. CONCLUSIONS Concentrations of sTLR-2 and sTLR-4 in vaginally obtained amniotic fluid do not reflect the presence of HCA in pregnancies complicated by preterm premature rupture of membranes before 34 weeks of gestation.

Abstract
Obstetrical complications, often referred to as the "great obstetrical syndromes," are among the most common global causes of mortality and morbidity in young women and their infants. However, treatments for these syndromes are underdeveloped compared with other fields of medicine and are urgently needed. This current paucity of treatments for obstetrical complications is a reflection of the challenges of drug development in pregnancy. The appetite of pharmaceutical companies to invest in research for obstetrical syndromes is generally reduced by concerns for maternal, fetal, and infant safety, poor definition, and high-risk regulatory paths toward product approval. Notably, drug candidates require large investments for development with an unguaranteed return on investment. Furthermore, the discovery of promising drug candidates is hampered by a poor understanding of the pathophysiology of obstetrical syndromes and their uniqueness to human pregnancies. This limits translational extrapolation and de-risking strategies in preclinical studies, as available for other medical areas, compounded with limited fetal safety monitoring to capture early prenatal adverse reactions. In addition, the ethical review committees are reluctant to approve the inclusion of pregnant women in trials, and in the absence of regulatory guidance in obstetrics, clinical development programs are subject to unpredictable regulatory paths. To develop effective and safe drugs for pregnancy complications, substantial commitment, and investment in research for innovative therapies are needed in parallel with the creation of an enabling ethical, legislative, and guidance framework. Solutions are proposed to enable stakeholders to work with a common set of expectations to facilitate progress in this medical discipline. Addressing this significant unmet need to advance maternal and possibly perinatal health requires the involvement of all stakeholders and specifically patients, couples, and clinicians facing pregnancy complications in the dearth of appropriate therapies. This paper focused on the key pharmaceutical research and development challenges to achieve effective and safe treatments for obstetrical syndromes.

Abstract
INTRODUCTION This study aimed to determine the incidence of lower genital infections and related factors in preterm premature rupture of membranes (PPROM) and preterm labor. METHODOLOGY A case-control study was conducted on pregnant women who were admitted to the Hospital of Hue University of Medicine and Pharmacy, Vietnam between November 2017 and May 2019. Cases from 22 to 36 gestational weeks were included as group 1 (patients with preterm labor and intact membranes) or as group 2 (those with PPROM). The control group included women with singleton pregnancies who were matched on gestational age and recruited concurrently with the study cases. Gram stain was perfomed to identify Lactobacillus, Gardnerella, mobiluncus, Candida, and leucocytes. Trichomonas vaginalis was detected by wet mount. Cultures of vaginal secretions and aminotic fluid were performed to identify aerobic bacteria. RESULTS Bacterial vaginosis was higher in group 1 (28.9%) compared to control (11.4%). The incidence of isolated aerobic bacteria was 44.1% in group 2, 11.1% in group 1, and 12.7% in the control group (p < 0.001). Fungal infection was not shown to be a risk factor for preterm labor (p = 0.990), whereas, bacterial vaginosis was (OR = 3.16; 95%CI = 1.23-8.15; p = 0.016). Isolated aerobic bacteria were associated with premature rupture of membranes (OR = 5.45; 95%CI = 2.11-14.05; p < 0.001). CONCLUSIONS Bacteria vaginosis increased the risk of preterm labor and preterm premature rupture of membranes. Isolated aerobic bacteria were related to PPROM, while fungal infection was not associated with preterm labor.

Abstract
OBJECTIVE To assess the association between vaginal microbiome (VMB) composition and recurrent early spontaneous preterm birth (sPTB)/preterm prelabour rupture of membranes (PPROM). DESIGN Nested case-control study. SETTING UK tertiary referral hospital. SAMPLE High-risk women with previous sPTB/PPROM <34+0 weeks' gestation who had a recurrence (n = 22) or delivered at ≥37+0 weeks without PPROM (n = 87). METHODS Vaginal swabs collected between 15 and 22 weeks' gestation were analysed by 16S rRNA gene sequencing and 16S quantitative PCR. MAIN OUTCOME MEASURE Recurrent early sPTB/PPROM. RESULTS Of the 109 high-risk women, 28 had anaerobic vaginal dysbiosis, with the remainder dominated by lactobacilli (Lactobacillus iners 36/109, Lactobacillus crispatus 23/109, or other 22/109). VMB type and diversity were not associated with recurrence. Women with a recurrence, compared to those without, had a higher median vaginal bacterial load (8.64 versus 7.89 log10 cells/mcl, adjusted odds ratio [aOR] 1.90, 95% CI 1.01-3.56, P = 0.047) and estimated Lactobacillus concentration (8.59 versus 7.48 log10 cells/mcl, aOR 2.35, (95% CI 1.20-4.61, P = 0.013). A higher recurrence risk was associated with higher median bacterial loads for each VMB type after stratification, although statistical significance was reached only for L. iners domination (aOR 3.44, 95% CI 1.06-11.15, P = 0.040). Women with anaerobic dysbiosis or L. iners domination had a higher median vaginal bacterial load than women with a VMB dominated by L. crispatus or other lactobacilli (8.54, 7.96, 7.63, and 7.53 log10 cells/mcl, respectively). CONCLUSIONS Vaginal bacterial load is associated with early sPTB/PPROM recurrence. Domination by lactobacilli other than L. iners may protect women from developing high bacterial loads. Future PTB studies should quantify vaginal bacteria and yeasts. TWEETABLE ABSTRACT Increased vaginal bacterial load in the second trimester may be associated with recurrent early spontaneous preterm birth.

Abstract
OBJECTIVES This study aimed to compare the serum IL-22 levels between preterm premature rupture of membranes (PPROM) patients and the control group with intact membranes. We also hypothesized whether serum IL-22 upregulation might contribute to defense against inflammatory responses and improve the pregnancy outcomes. MATERIAL AND METHODS We performed this prospective case-control study between 24-34 weeks of pregnancy. We enrolled 40 singleton pregnant patients with PPROM and 40 healthy gestational age- and gravidity-matched patients without PPROM. The degree of association between variables and IL-22 were calculated by Spearman correlation coefficients where appropriate. Scatter plots were given for statistically significant correlations. ROC curve was constructed to illustrate the sensitivity and specificity performance characteristics of IL-22, and a cutoff value was estimated by using the index of Youden. RESULTS Maternal serum IL-22 levels were significantly higher in PPROM patients (60.34 ± 139.81 pg/mL) compared to the participants in the control group (20.71 ± 4.36 pg/mL, p < 0.001). When we analyze the area under the ROC curve (AUC), the IL-22 value can be considered a statistically significant parameter for diagnosing PPROM. According to the Youden index, a 23.86 pg/mL cut-off value of IL-22 can be used to diagnosing PPROM with 72% sensitivity and 61.5% specificity. There was no positive correlation between serum IL-22 levels and maternal C-reactive protein (CRP) value, procalcitonin value, latency period, birth week, birth weight, and umbilical cord blood pH value. CONCLUSIONS Maternal serum IL-22 levels were significantly higher in PPROM patients than healthy pregnant women with an intact membrane. We suggest that IL-22 might be a crucial biomarker of the inflammatory process in PPROM.

Abstract
Despite the progress of medicine in the last decades, recurrent pregnancy loss, premature birth, and related complications are still a vast problem. The reasons for recurrent pregnancy loss and preterm delivery are diverse and multifactorial. One of the main reasons for these complications is cervical insufficiency, which means that the cervix is weak and unable to remain closed until the date of delivery. It manifests as painless softening and shortening of the cervix without contractions. The aim of the study was to review the available literature on rescue sutures, which are an emergency treatment in pregnancies with premature cervical dilatation and protrusion of the fetal membranes in the second trimester of pregnancy. This review confirms that emergency cerclage reduces the rate of preterm birth in patients with advanced cervical insufficiency. This procedure prolongs gestational age and improves the chances of survival of the newborn without increasing the risk of chorioamnionitis and preterm premature rupture of membranes.

Abstract
This study aimed to clarify the association between uterine myomas and preterm birth (PTB), preterm premature rupture of membranes (pPROM), and intrauterine infection (II). The study was based on data from the Japan Environment and Children’s Study, a nationwide birth-cohort study. Data of 86,370 women with singleton births after 22 weeks of gestation (with uterine myomas, n = 5354) were retrospectively analyzed. Using logistic regression, adjusted odds ratios (aORs) for PTB, pPROM, and II were calculated considering women without uterine myomas as the reference. Additionally, the effects of II on the incidence of PTB and pPROM were evaluated. In women with uterine myomas, the aORs for PTB before 37 and 34 weeks, pPROM, and II were 1.37 (95% confidence interval, 1.22–1.54), 1.61 (1.27–2.05), 1.65 (1.33–2.04), and 1.05 (0.75–1.46), respectively. The aORs for PTB and pPROM in women with II and uterine myomas were not significantly increased. Uterine myomas during pregnancy were associated with an increased incidence of PTB and pPROM. However, II in women with uterine myomas was not associated with an increased incidence of PTB or pPROM. These findings suggest a potential risk of occult PTB in pregnant women with uterine myomas.

Abstract
BACKGROUND Following the destruction of pharmaceutical production facilities in Puerto Rico by Hurricane Maria in September 2017, a shortage of small-volume bags of sterile intravenous fluid for infusion led to a decreased ability to administer intravenous azithromycin and ampicillin efficiently for use in the treatment of patients with preterm premature rupture of membranes. OBJECTIVE This study aimed to assess pregnancy latency after preterm premature rupture of membranes following treatment with oral-only antibiotics compared with treatment with intravenous antibiotics followed by oral antibiotics. STUDY DESIGN This is a retrospective historic control study comparing women with preterm premature rupture of membranes who were initiated on a 7-day oral-only regimen of azithromycin and amoxicillin (modified regimen) during a 12-month period beginning December 2017 (during which time there was a shortage of small-volume bags of intravenous fluid) to women with preterm premature rupture of membranes who were initiated on a 2-day regimen of intravenous ampicillin and azithromycin followed by 5 days of oral amoxicillin and azithromycin (standard regimen) from December 2016 to December 2018. Women were included in the study if they were diagnosed with preterm premature rupture of membranes at <34 weeks' gestation and were started on latency antibiotics, and women were excluded from the study if they had a contraindication to expectant management, a cerclage, or suspected fetal anomalies. The primary outcome was pregnancy latency, defined as time from the first dose of antibiotics to delivery. RESULTS The 37 women who received the modified regimen and the 79 women who received the standard regimen had similar baseline characteristics. Mean (standard deviation) gestational age at time of preterm premature rupture of membranes was similar between the modified (30.5 weeks' gestation [±3.1]) and standard regimen groups (30.2 weeks' gestation [±3.2]), and the rate of group B streptococcus rectovaginal colonization was similar for both groups (27% vs 24%; P=.95). Pregnancy latency did not differ in the modified vs standard regimen (mean difference, -0.15 days; 95% confidence interval, -4.87 to 4.58) There was no statistically significant difference in the relative risk of composite maternal infection (relative risk, 0.43; 95% confidence interval, 0.05-3.53) or composite neonatal infection (relative risk, 0.43; 95% confidence interval, 0.05-3.52). CONCLUSION Although limited by small sample size, our study suggested that adoption of an oral-only antibiotic regimen for pregnancy latency following preterm premature rupture of membranes is worthy of further study.

Abstract
OBJECTIVE To evaluate the causes of MTM and their impact on subsequent pregnancies. MATERIAL AND METHODS A retrospective single-center cohort study of all pregnancies with a second-trimester pregnancy loss between 14 weeks and 21 weeks + 6 days gestation, excluding terminations of pregnancy (TOP) and in utero fetal deaths. Predefined criteria were used to allocate cases to one of 6 primary etiologic diagnoses: cervical insufficiency, chorioamnionitis, placental anomalies, fetal anomalies, iatrogenic causes, or abdominal trauma. RESULTS Among 578 mid-trimester fetal losses, 175 were MTM, a prevalence of 5.7 per 1000 live births in the center. The suspected primary cause was cervical insufficiency in 76 cases (43.4%), chorioamnionitis in 59 (33.7%), placental anomalies or preterm premature rupture of membranes in 26 (14.8%), iatrogenic in 8 (4.6%), trauma in 3 (1.7%), and undetermined in 3 cases (1.7%). A subsequent pregnancy beyond 14 WG was recorded for 78 patients. Recurrent MTM occurred in 21.8% and preterm deliveries in 14.1% ; 13% of patients without evidence of cervical insufficiency in the index pregnancy required emergency cerclage. CONCLUSION Cervical insufficiency was the leading cause of MTM, with a high risk of recurrent MTM or preterm birth, thus prophylactic cerclage or cervical length measurements should be considered for subsequent pregnancies.
