Objective: To examine whether a history of hysteroscopic adhesiolysis (HA)‐treated intrauterine adhesions (IUAs) was associated with an increased risk of adverse obstetrical outcomes in subsequent pregnancies. Design: Retrospective cohort study. Setting: A tertiary‐care hospital in Shanghai, China. Population: A cohort of 114 142 pregnant women who were issued an antenatal card and received routine antenatal care in Shanghai First Maternity and Infant Hospital, between January 2016 and October 2021. Methods: From the cohort of 114 142 pregnant women, each woman with a history of HA‐treated IUA prior to the current pregnancy (n = 780) was matched with four women without a history of IUAs (n = 3010) using propensity score matching. The matching variables were maternal age and parity, mode of conception, pre‐pregnancy body mass index and prior history of abortion. Main outcome measures: Pregnancy complications, placental abnormalities, postpartum haemorrhage and adverse birth outcomes. Results: Compared with women with no history of IUAs, women with a history of HA‐treated IUAs were at higher risk of pre‐eclampsia (RR 1.69, 95% CI 1.23–2.33), placenta accreta spectrum (RR 4.72, 95% CI 3.9–5.73), placenta praevia (RR 4.23, 95% CI 2.85–6.30), postpartum haemorrhage (RR 2.86, 95% CI 1.94–4.23), preterm premature rupture of membranes (RR 3.02, 95% CI 1.97–4.64) and iatrogenic preterm birth (RR 2.86, 95% CI 2.14–3.81). Those women were also more likely to receive cervical cerclage (RR 5.63, 95% CI 3.95–8.02) during pregnancy and haemostatic therapies after delivery (RR 2.17, 95% CI 1.75–2.69). Moreover, we observed that the RRs of those adverse obstetrical outcomes increased with the increasing number of hysteroscopic surgeries. Conclusions: This study found that a history of HA‐treated IUAs, especially a history of repeated HAs, was associated with an increased risk of adverse obstetrical outcomes. [ABSTRACT FROM AUTHOR]

Intra-amniotic infection (IAI), also known as chorioamnionitis, is a major cause of maternal and neonatal infection that occurs during pregnancy, labor and delivery, or in the postpartum period. Conditions such as meconium-stained amniotic fluid (MSAF) and premature rupture of membranes (PROMs) are recognized risk factors for amniotic fluid infection. This study identifies the microbial patterns in the amniotic fluid of women with PROMs and MSAF to determine the presence and types of bacterial growth. It also identifies trends in antibiotic use through descriptive statistics. Conducted as a descriptive observational study with prospective data collection, this research included maternal patients with PROMs lasting more than 12 h and those with MSAF, along with their infants. Of 30 cultured amniotic fluid samples, bacterial growth was observed in 13 cases, with Escherichia coli being the most prevalent (40%). Infants born with PROMs accompanied by MSAF were 5.5 days, significantly longer than those born with PROMs alone (3.19 days) or MSAF alone (3.91 days), with a significant difference between groups (p = 0.003). In addition, Escherichia coli isolates in this study are resistant to ceftriaxone, a third-generation cephalosporin antibiotic. Understanding these microbial patterns is critical for guiding clinical decisions, particularly in managing the risk of infection in pregnant women with PROMs and MSAF and ensuring better outcomes for both mothers and newborns.

Background: Chorioamnionitis is recognized as a major consequence of preterm premature rupture of membranes (PPROM), and a frequent cause of neonatal morbidity and mortality. The association between fetal heart rate (FHR) and chorioamnionitis remains unclear. Objectives: The aim of this study was to evaluate the dynamics of FHR in a PPROM population at the approach of delivery according to the presence or absence of chorioamnionitis. Materials & methods: 120 pregnant women with PPROM between 26 and 34 weeks' gestation were enrolled in this multicenter prospective unblinded study. All participants were fully informed of the study's objectives. 39 of the 120 patients were included in the analysis of FHR recordings. The analysis consisted of extracting features from computerized FHR analysis (cFHR) and fetal heart rate variability analysis (FHRV) in the temporal, frequency and nonlinear domains. Then, each set of features was analyzed separately using the multiple factor analysis, where three groups were defined as the feature set for days 0, -1 and -2 prior to birth. The distances between the global projection and the projections for each day were computed and used in the ROC analysis to distinguish chorioamnionitis from non-chorioamnionitis group. Results: The results showed that there were significant differences in certain features between populations with and without chorioamnionitis. The distinction between the two populations reached an area under the curve (AUC) of only 37% [34–40] for cFHR features and 63% [59–66] for time-domain FHRV features when comparing all stages of chorioamnionitis to non-chorioamnionitis subjects. When only stage 3 chorioamnionitis was compared to non-chorioamnionitis patients, the AUC reached 90% [88–93] for nonlinear-domain and 84% [82–87] for time-domain FHRV features, whereas it was limited to 71% [68–74] using cFHR features. Conclusion: The present study suggests that the HRV features are more reliable for diagnosing chorioamnionitis than cFHR, and that the assessment of features dynamics over several days is an interesting tool for detecting chorioamnionitis. Further study should be carried out on a larger sample to confirm these findings, improve the diagnostic performance of chorioamnionitis and help clinicians decide on delivery criteria.

Objective: This study aimed to assess whether a partial term prelabor rupture of membranes (partial TPROM) had an impact on the spontaneous onset of labor compared to complete TPROM. Methods: We performed a retrospective study in a French level III maternity hospital. We included all singleton cephalic pregnancies presenting with prelabor rupture of membranes ≥37 weeks gestational age. Patients with a partial TPROM (P group) were compared to patients with a complete TPROM (C group). Induction of labor was performed following expectative management of 24–48 h, and antibiotic prophylaxis was started 12 h after rupture. Our main outcome measure was the rate of patients who had spontaneous labor 24 h following prelabor rupture. Results: Overall, 389 women were included in the study, 148 in the P group, 241 in the C group. The proportion of women who went into spontaneous labor in the 24 h following TPROM was significantly lower in the P group (45% vs 64%, P < 0.001). A partial TPROM was a predictive factor for absence of labor at 24 h following rupture (adjusted odds ratio: 0.44 [0.29–0.68]). There were more cases of induction of labor (50% vs 20%, P < 0.001) and antibiotic prophylaxis (91% vs 73%, P < 0.001) in the P group. However, obstetrical and neonatal outcomes were comparable between the two groups. Conclusion: Compared to complete TPROM, partial TPROM is associated with a lower probability of spontaneous labor in the 24 h following rupture. The persistence of a residual membrane has been identified as a risk factor for delaying labor beyond 24 h. Synopsis: The onset of labor within the first 24 h of rupture was less frequent if the prelabor rupture of membranes was incomplete. [ABSTRACT FROM AUTHOR]

Women with uterine myomas have increased rates of preterm delivery; however, data on other adverse pregnancy events conflict, and myomectomy does not appear to confer benefit. There is a prevailing opinion by gynecologists, much of it based on expert opinion or anecdotal evidence, that myomas are detrimental to pregnancy. Newer data challenge much of this dogma, but incorrect assumptions remain. Although not impeccable, multiple data address the correlation between myomas and reproduction, and some emerging evidence addresses surgical removal of these myomas and subsequent outcomes. A thorough literature search was performed, and the amassed data were analyzed to answer some of our most important queries about the role that myomas play in pregnancy and delivery. Uterine leiomyomas ultimately decrease in size during late pregnancy and postpartum. Spontaneous abortion rates are similar in women with and without leiomyomas. The data addressing leiomyoma effects on preterm prelabor rupture of membranes, placental abruption, cesarean delivery, and postpartum hemorrhage rates are conflicting, but the best evidence does not show a significant correlation compared with women without myomas. Preterm delivery rates are elevated in women with leiomyomas. Myomectomy does not decrease preterm deliveries and may increase this risk. Women with myomectomies have increased elective cesarean delivery rates and more blood loss at delivery compared with women with leiomyomas in situ. [ABSTRACT FROM AUTHOR]

There are multiple risk factors for preterm birth (PTB), one of the most important of which is mood disorders during pregnancy. We aimed to comprehensively investigate the association of both total mental health concerns and ten specific psychiatric symptoms with PTB risk. A cohort study was performed consisting of 25,175 pregnant women who participated in Women and Children's Hospital of Chongqing Medical University between 2020 and 2022. The Symptom Checklist 90 (SCL-90) was utilized to assess the psychiatric symptoms. Multivariable or multinomial logistic regression was applied to investigate mental health concerns associated with risk of PTB or its different clinical sub-categories, respectively. Sensitivity analyses were further performed to validate the results. 8336 women who met the inclusion criteria were included; of these, 547 (6.6 %) had preterm deliveries, and 2542 (30.5 %) had mental health concerns. Compared with women with healthy minds, women with total mental health concerns had a 29.0 % higher risk of overall PTB (OR = 1.28, 95%CI = 1.07–1.54), medical-induced PTB (OR = 1.49, 95%CI = 1.05–2.13) and spontaneous PTB with premature rupture of membranes (OR = 1.33, 95%CI = 1.01–1.74). As to the specific psychological symptoms, hostility pregnant women had a 55.0 % higher risk of PTB (OR = 1.55, 95%CI = 1.14–2.11). Similar results were observed in most of the sensitivity analyses. This is a single-center study, thus the extrapolation of the results may be limited. Pregnant women with mental health symptoms, especially hostility, have an increased risk of PTB. The findings underscore that integrating mental health services into routine maternal care may be a strategy to prevent PTB. • Few studies have comprehensively evaluated psychiatric symptoms with preterm birth risk • We investigated both total mental health concerns and ten specific symptoms with risk of preterm birth and its different clinical sub-categories • Women with total mental health concerns had a 29 % higher risk of preterm birth • For the specific symptoms, hostility pregnant women had a 55 % higher risk of preterm birth • The results highlight that integrating mental health services into routine maternal care may be a strategy to prevent preterm birth [ABSTRACT FROM AUTHOR]

To evaluate population characteristics and obstetric complications after abdominal myomectomy vs. laparoscopic myomectomy. Retrospective cohort study. A total of 13,868 and 338 pregnancies after abdominal or laparoscopic myomectomy, respectively. Obstetrics outcomes following abdominal and laparoscopic myomectomy were collected. Obstetric outcomes after abdominal or laparoscopic myomectomies were collected using hospital discharges from 2004 to 2014 inclusively, and adjusted using multiple and binomial logistic regression in different models for age, obesity, chronic hypertension, and pregestational diabetes mellitus. Pregnancy, delivery, and neonatal outcomes were analyzed. Abdominal myomectomy were characterized by younger patients, lower rates of Caucasian, chronic hypertension, pregestational diabetes, active smoking, illicit drug use, and higher rates of previous cesarean delivery, and multiple gestations when compared with laparoscopic myomectomy. Pregnant women with laparoscopic myomectomy had decreased rates of pregnancy-induced hypertension (adjusted risk ratios [aRR], 0.12; 95% confidence intervals [CI], 0.006–0.24]), gestational hypertension (aRR, 0.24; 95% CI, 0.08–0.76), pre-eclampsia (aRR, 0.18; 95% CI, 0.07–0.48), and pre-eclampsia or eclampsia superimposed on chronic hypertension (aRR, 0.03; 95% CI, 0.005–0.3), gestational diabetes mellitus (aRR, 0.14; 95% CI, 0.06–0.34), preterm premature rupture of membranes (aRR, 0.14; 95% CI, 0.02–0.96), preterm delivery (aRR, 0.36; 95% CI, 0.23–0.55), and cesarean delivery (aRR, 0.01; 95% CI, 0.007–0.01) and small for gestational age (aRR, 0.15; 95% CI, 0.005–0.04), compared with abdominal myomectomy group. Laparoscopic myomectomy group had a higher rate of spontaneous (aRR, 35.57; 95% CI, 22.53–62.66), and operative vaginal delivery (aRR, 10.2; 95% CI, 8.3–12.56), uterine rupture (aRR, 6.1; 95% CI, 3.2–11.63), postpartum hemorrhage (aRR, 3.54; 95% CI, 2.62–4.8), hysterectomy (aRR, 7.74; 95% CI, 5.27–11.4), transfusion (aRR, 3.34; 95% CI, 2.54–4.4), pulmonary embolism (aRR, 7.44; 95% CI, 2.44–22.71), disseminated intravascular coagulation (aRR, 2.77; 95% CI, 1.47–5.21), maternal infection (aRR, 1.66; 95% CI, 1.1–2.5), death (aRR, 2.04; 95% CI, 1.31–3.2), and intrauterine fetal death (aRR, 2.99; 95% CI, 1.72–5.2) compared with the abdominal myomectomy group. Women who had a previous abdominal myomectomy have underlying risk factors for hypertension disorders of pregnancy and gestational diabetes. Women who underwent laparoscopic myomectomies have higher risks of bleeding, uterine rupture, resultant complications, and death, and should be monitored as high-risk patients, like abdominal myomectomies.

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease primarily impacting women of childbearing age. While pregnancy and hormonal stress can trigger SLE flare-ups, the effects of assisted reproductive therapies (ARTs) on SLE patients are not well defined. We conducted a search of PubMed/Medline, Embase, and CENTRAL until March 20, 2024, to find observational studies assessing the prevalence of SLE flares and pregnancy outcomes following ARTs. Our analysis included random-effects meta-analysis and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach for evaluating evidence quality. Five studies involving 237 SLE women who underwent ARTs were eligible. The meta-analysis indicated a prevalence of SLE flares at 17% (95% CI: 10–25%) with moderate-quality evidence. The pooled prevalence of arthritis flares was 7% (95% CI: 0–25%) with low-quality evidence. Successful pregnancy rates were 58% (95% CI: 43–72%), and live birth rates were 96% (95% CI: 83–100%), both with low-quality evidence. Moderate-quality evidence showed pregnancy complications, including preterm premature rupture of membranes (PPROM) at 8% (95% CI: 3–16%), miscarriages at 2% (95% CI: 0–9%), intrauterine fetal demise (IUFD) at 4% (95% CI: 0–11%), and preeclampsia at 7% (95% CI: 1–17%). Low-quality evidence showed preterm labor at 10% (95% CI: 0–32%) and ovarian hyperstimulation syndrome (OHSS) at 2% (95% CI: 0–11%). SLE flares, as well as pregnancy complications such as IUFD, miscarriage, PPROM, and preeclampsia in ART recipients, are equivalent to those in spontaneous conception. This indicates that ART is relatively safe for SLE patients with meticulous pregnancy planning. Key Points • Systemic lupus erythematosus (SLE) is a chronic autoimmune disease primarily impacting women of childbearing age. • Pregnancy in women with SLE poses elevated maternal and fetal risks compared to healthy women. • SLE flares and pregnancy complications while receiving ART are equivalent to those in spontaneous conception and ART is relatively safe for SLE patients.

Purpose: The purpose of this study is to compare obese and non-obese women with multiple pregnancies to determine the effects on pregnancy, delivery, and neonatal outcomes. Methods: We conducted a retrospective population-based study utilizing data collected between 2004 and 2014 inclusively, from the Healthcare Cost and Utilization Project-Nationwide Inpatient Sample. A total of 137,303 multiple pregnancies were analyzed; 130,542 (95%) were non-obese, while 6761 (5%) were obese. An initial analysis was performed to identify the prevalence of obesity in women with multiple pregnancies. Subsequently, chi-square tests and binary logistic regression analyses were conducted to assess the association between obesity and multiple gestation in the context of obstetric complications. Results: There was a statistically significant increase in the prevalence of obesity for women with multiple gestations (p < 0.0001). The obese group was at higher risk of pregnancy-induced hypertension (adjusted odd's ratio [aOR] = 1.89, 95% confidence interval [CI] = 1.77–2.02), gestational hypertension (aOR = 1.84, CI = 1.65–2.05), preeclampsia (aOR = 1.68, CI = 1.55–1.81), preeclampsia or eclampsia superimposed on pre-existing hypertension (aOR = 1.86, CI = 1.58–2.20), gestational diabetes mellitus (aOR = 2.65, CI = 2.44–2.87), and placenta previa (aOR = 0.57, CI = 0.39–0.85). They were more likely to have preterm premature rupture of membranes (aOR = 1.19, CI = 1.06–1.34), chorioamnionitis (aOR = 1.24, CI = 1.03–1.51), caesarean deliveries (aOR = 1.28, CI = 1.18–1.38), wound complications (aOR = 1.65, CI = 1.31–2.08), and transfusions (aOR = 0.77, CI = 0.67–0.89). They were less likely to have small for gestational age neonates (aOR = 0.88, CI = 0.79–0.97), though more likely to have neonates with congenital anomalies (aOR = 1.56, CI = 1.16–2.10). Conclusion: Obesity and multiple gestations are independent risk factors for adverse obstetric outcomes. Combined, when analyzed in a large population, obesity in multiple gestation increases the risk of maternal, delivery, and neonatal complications. [ABSTRACT FROM AUTHOR]

Objective: There are conflicting data on whether fetoscopic laser photocoagulation (FLP) of placental anastomoses for the treatment of twin‐to‐twin transfusion syndrome (TTTS) is associated with lower rates of overall survival. The objective of this study was to characterize twin survival and associated morbidity according to the gestational age at which FLP was performed. Methods: This was a secondary analysis of data collected prospectively on patients with a monochorionic diamniotic (MCDA) twin pregnancy who underwent FLP for TTTS at two centers between January 2011 and December 2022. Patients were divided into six groups according to gestational age at the time of FLP: < 18 weeks, 18 + 0 to 19 + 6 weeks, 20 + 0 to 21 + 6 weeks, 22 + 0 to 23 + 6 weeks, 24 + 0 to 25 + 6 weeks and ≥ 26 weeks. Demographic characteristics, sonographic characteristics of TTTS and operative characteristics were compared across the gestational age epochs. Outcomes, including overall survival, preterm delivery (PTD), preterm prelabor rupture of membranes (PPROM), intrauterine fetal demise (IUFD) and neonatal demise (NND), were also compared across gestational age epochs. Multivariate analysis was performed by fitting logistic regression models for these outcomes. Kaplan–Meier curves were constructed to compare the interval from PPROM to delivery between gestational age epochs. Results: There were 768 patients that met the inclusion criteria. The rate of dual twin survival was 61.3% for cases in which FLP was performed before 18 weeks, compared with 78.0%–86.7% when FLP was performed at ≥ 18 weeks' gestation. This appears to be driven by an increased rate of donor IUFD following FLP performed before 18 weeks (28.0%) compared with ≥ 18 weeks (9.3–14.1%). Rates of recipient IUFD and NND and donor NND were similar regardless of gestational age at FLP. The rate of PPROM was higher for FLP conducted at earlier gestational ages, ranging from 45.6% for FLP before 18 weeks to 11.9% for FLP performed at 24 + 0 to 25 + 6 weeks' gestation. However, gestational age at delivery was similar across gestational age epochs, with a median of 31.7 weeks. On multivariate analysis, donor twin loss was associated with FLP before 18 weeks, even after adjusting for selective fetal growth restriction, Quintero stage and other covariates. PPROM and PTD were also associated with FLP performed before 18 weeks after adjusting for cervical length, placental location, trocar size, laser energy and amnioinfusion. Conclusions: FLP performed at earlier gestational ages is associated with lower overall survival, which is driven by the increased risk of donor IUFD, as opposed to differences in the rate of PPROM or PTD. Parental counseling regarding twin survival should account for the gestational age at which patients present with TTTS. © 2024 International Society of Ultrasound in Obstetrics and Gynecology.

Objective To examine the effect of underweight maternal body mass index (BMI) on pregnancy complications and neonatal outcomes. Design Cohort study. Setting Tertiary academic center. Patients A total of 16 361 mothers who delivered a singleton between 2015-2021 with either a BMI <18.5 kg/m2 (n = 732) or normal BMI (18.5 ≥ BMI <23 or 25 kg/m2, n = 15 629) at the initial prenatal visit or within 6 months of the initial visit. Main Outcome Measures Birthweight, gestational age, neonatal intensive care unit admission, preterm birth, and fetal death; obstetrical complications including preeclampsia/eclampsia, premature rupture of membranes, preterm premature rupture of membranes, and postpartum hemorrhage. Results Underweight women were younger and less likely to have private insurance (P <.01 for both) than normal-weight women. Approximately 23% of infants born to underweight mothers were small for gestational age and 15% were low birth weight vs 13.5% and 9% of infants of normal-weight mothers, respectively (P <.01 for both). These differences remained significant after adjusting for potential confounders. In adjusted logistic regression models, underweight women had a decreased risk of premature rupture of membranes and postpartum hemorrhage compared to normal-weight women. Conclusion Underweight BMI during pregnancy is associated with an increased risk of small for gestational age and low birth weight infants and a decreased risk of premature rupture of membranes and postpartum hemorrhage. These findings suggest underweight BMI during pregnancy increases the risk of adverse neonatal outcomes, while maternal-related pregnancy outcomes are less affected. [ABSTRACT FROM AUTHOR]

Background: Premature rupture of the membrane (PROM), refers to rupture of the fetal membranes prior to the onset of regular uterine contractions. When this occurs at term (≥ 37 weeks of gestation), it is classified as PROM, whereas if it occurs before 37 weeks, it is termed preterm premature rupture of membranes (PPROM). PROM and PPROM are linked to adverse outcomes for both mother and newborn. Objectives: To investigate the factors associated with PROM and the outcomes of pregnancies complicated with PROM. Methods: This was a retrospective cohort study. The participants were divided into three groups; those with PROM, those with PPROM and a control group who had normal onset of membranes rupture. The groups were compared with respect to predictors of PROM (maternal demographic profile, obstetrical history, and comorbidities), in addition to outcomes (postpartum hemorrhage, hospital stay, low APGAR scores, sepsis, low birthweight, preterm rate, and admission to neonatal Intensive care Unit (NICU)). Multivariable logistic regression model was used for predicting risk factors associated with PROM and PPROM. Results: A total of 1,894 pregnant women were enrolled in the study, 77.6% had normal onset of ruptured membranes, while 382 (20.1%) were diagnosed with a PROM and 43 (2.3%) diagnosed with PPROM. Primiparous mothers were more likely to develop PROM (AOR = 1.56, 95% CI (1.10–2.22)) as compared to multiparous, while obese and overweight mothers were less likely to develop PPROM (AOR = 0.86, 95% CI (0.94 − 0.49)). Significantly more mothers with PPROM were delivered by emergency cesarean Sect. (30.2% vs. 22.9%, P < 0.01), develop chorioamnionitis (4.7% vs. 0.1%, P < 0.01), and stayed in the hospital more than three days (16.3% vs. 2.5%, P < 0.01) compared to the control group. Neonates of mothers who had PPROM were more likely to have low birth weight (35.7% vs. 10.4%, P < 0.01), and NICU admission (67.4% vs. 20.4%, P < 0.01) as compared to the control group. Perinatal death rate was not significantly different between the groups. Conclusion: In this study, nulliparity is a predictor of PROM, while overweight/ obese mothers are less likely to develop PPROM. Despite the relatively low occurrence of PPROM among Saudi women, the condition is associate with increase risk of cesarean section delivery, chorioamnionitis, prolonged hospitalization, and an increase need for neonatal intensive care compare to those with a normal onset of membrane rupture.

Previous studies have investigated whether inflammatory cytokines in maternal circulation are associated with preterm birth. However, many have reported inconsistent results, and few have investigated cytokine trends through gestation, particularly with respect to subtypes of preterm birth. We explored levels of 15 inflammatory cytokines and growth factors in plasma and serum collected in the second (17–23 weeks, timepoint 1 (T1)) and third (28–32 weeks, timepoint 2 (T2)) trimesters with respect to subtypes of preterm birth: spontaneous preterm labour (sPTL), preterm premature rupture of membranes (PPROM), and medically indicated preterm birth (mPTB). The change in TNFα levels over time (T2/T1) significantly classified mPTB from term birth with an AUC of 0.79. While elevated sICAM-1 levels were significantly associated with sPTL, sICAM-1 was not an effective biomarker for prediction. While statistical differences in some biomarkers, such as TNFα and sICAM-1 were found, these are likely not clinically meaningful for prediction. These results did not reveal a relationship between spontaneous labour and circulating maternal inflammatory biomarkers, however, do suggest distinct inflammatory profiles between subtypes of preterm birth.

Takayasu's arteritis (TA) is a rare, chronic inflammatory disease of unknown cause, primarily affecting young women in their reproductive years. It can result in the narrowing and occlusion of arteries and the formation of aneurysms in arteries, especially those related to the aorta, creating significant risks during pregnancy. Women with TA are more susceptible to cardiovascular complications, including hypertension and heart failure, which can negatively affect both maternal and fetal health. This case report details a 23‐year‐old pregnant woman diagnosed with TA during the first trimester, presenting with symptoms of fainting and pulselessness in her right upper limb. Doppler imaging of the right upper limb confirmed the diagnosis. Treatment for TA was initiated alongside comprehensive antenatal care. In the third trimester, she also developed gestational hypertension. And at 36 weeks of gestation, due to placenta previa and preterm premature rupture of membranes, an emergency cesarean section was performed. Timely medical intervention resulted in a favorable outcome, with an uneventful postpartum recovery. This case highlights the need for early diagnosis and collaborative care in pregnant women with TA to ensure better outcomes for both mother and child. Understanding the clinical aspects of TA is essential for effective management and improved prognosis. [ABSTRACT FROM AUTHOR]

A 40-year-old woman who had obstetric history of one vaginal delivery and two surgical abortions to terminate early pregnancy received regular prenatal care without any systemic maternal diseases. During the detailed second trimester ultrasound, a homogenous adhesion-induced pseudocystic lesion of 8.6 × 7.4 cm was found between the inlet of the endocervix and the uterine cavity in the lower segment of the uterus. There was a clear septum with an inlet of about 2.6 cm near the right lower segment of the uterus. Transvaginal sonography showed a cervical length of 3.29 cm without dilatation. No gross fetal anomalies were found. Sometimes, the fetal head or limbs moved into this cystic space. At 36 3/7 weeks of gestation, a cesarean section was arranged for fetal breech presentation and pre-labor rupture of the membrane. After the delivery of the baby and its placenta, there was no obvious septum in the uterine cavity but only a very short fibrous tissue from the posterior wall of uterus, which could be destroyed when the baby was delivered. No adverse outcomes for the mother or the neonate were observed. [ABSTRACT FROM AUTHOR]

Introduction: Chronic endometritis (CE) is a prolonged, mild inflammation of the endometrial lining. This study investigated the impact of the impact of antibiotic treatment combined with vaginal Lactobacillus on pregnancy outcomes in infertile patients with CE during frozen embryo transfer (FET) cycles. Methods: A retrospective analysis was performed on the clinical data of 7,385 patients who underwent FET. After applying the inclusion and exclusion criteria, 254 patients diagnosed with CE were eligible for inclusion. Of these, 119 patients received antibiotics alone, whereas 135 were treated with a combination of doxycycline and vaginal Lactobacillus. All patients underwent embryo transfer within 6 months following treatment. The general characteristics and pregnancy outcomes of the first FET cycle post-treatment were compared between the two groups. Results: There were no statistically significant differences between the two groups in terms of general characteristics, clinical pregnancy rate, early miscarriage rate, and ectopic pregnancy rate. Patients who received a combination of doxycycline and Lactobacillus showed a higher biochemical pregnancy rate compared to those who received doxycycline alone, though this difference was not statistically significant (70.37% vs. 64.71%, P=0.313). Furthermore, the incidence rate of premature rupture of membranes was lower in the doxycycline- Lactobacillus group than in the doxycycline group (50.00% vs 33.33%, P=0.037). Conclusions: Although this study observed the potential benefits of the antibiotic and vaginal probiotic treatment regimen in increasing the biochemical pregnancy rate and reducing the incidence of premature rupture of membranes, the current findings are insufficient to recommend the combined use of antibiotics and vaginal Lactobacillus as an intervention to improve reproductive outcomes in infertile patients with CE.

Background: Preterm birth is a significant concern in multiple pregnancies, warranting effective strategies to improve outcomes. Delaying delivery of the second fetus is crucial for reducing perinatal mortality rates. Case Presentation: In a dichorionic diamniotic twin pregnancy, one fetus experienced premature rupture of membranes (PROM) at 16+6 weeks gestation. Proactive fetal reduction through potassium chloride injection and emergency cervical cerclage at 19+1 week successfully extended the pregnancy to 39+5 weeks, resulting in a notable 160-day prolongation. Postoperative management encompassed comprehensive tocolytic therapy. Conclusion: The combined approach of proactive fetal reduction and emergency cervical cerclage proved successful in managing PROM in dichorionic diamniotic twin pregnancies. This innovative strategy offers a promising clinical solution for optimizing outcomes and prolonging gestation in high-risk multiple pregnancies, underscoring the importance of tailored interventions in complex obstetric scenarios.

Introduction: Premature rupture of membranes (PROM) before 37 weeks of gestation is a common obstetrical event, whose pathophysiology is still poorly understood. Our objective was to study the mechanical strength of fetal membranes in women with a clinical risk factor for preterm premature rupture of membranes (PPROM). Methods: We included, in a prospective, descriptive, single-center study, patients scheduled for cesarean section at term (≥ 37 weeks of gestation). For each patient, we performed uniaxial tensile tests on fetal membranes with a universal testing machine equipped with a force sensor (EZ20®, Lloyds), allowing the recording of an applied force/time curve. We collected maximum force (Fmax), maximum stress (σMax), and Young's modulus of elasticity. The thickness of each membrane sample was also measured. We compared the values obtained according to certain clinical risk factors for PPROM such as age, body mass index, gravidity, parity, a history of PPROM or preterm birth, smoking, gestational diabetes, geographic origin, and socioeconomic level. Results: We analyzed 31 patients and found no association between the studied risk factors and σMax. Fmax was lower in primiparous patients (p = 0.02) but increased with patient parity (p = 0.005). Gestational diabetes was associated with a higher Fmax (p = 0.033) and sub-Saharan geographical origin with a greater thickness (p = 0.0043). As membrane thickness increased, σMax (p = 0.009) and Young's modulus decreased (p = 0.037). Conclusion: Primiparous patients have lower membrane mechanical strength than patients who have had one or more deliveries. Mechanically, the thicker membranes are less rigid and less resistant.

ABSTRACT Objectives Methods Results Conclusions First, to report the incidence of non‐cephalic presentation at a routine 36‐week ultrasound scan, the uptake and success of external cephalic version (ECV) and the incidence of spontaneous rotation from non‐cephalic to cephalic presentation. Second, to determine the maternal and pregnancy characteristics that provide a significant contribution to the prediction of non‐cephalic presentation at the 36‐week scan, successful ECV from non‐cephalic to cephalic presentation and spontaneous rotation from non‐cephalic to cephalic presentation.This was a retrospective analysis of prospectively collected data from 107 875 women with a singleton pregnancy who had undergone a routine ultrasound scan at 35 + 0 to 36 + 6 weeks' gestation. Patients with breech or transverse/oblique presentation were divided into two groups: those scheduled for elective Cesarean section for a fetal or maternal indication other than abnormal presentation, and those that would potentially require ECV. The latter group was reassessed after 1–2 weeks and, if the abnormal presentation persisted, the parents were offered ECV or elective Cesarean section at 38–40 weeks' gestation. Multivariable logistic regression analysis was carried out to determine which maternal and pregnancy characteristics provided a significant contribution in the prediction of non‐cephalic presentation at the 36‐week scan, successful ECV from non‐cephalic to cephalic presentation and spontaneous rotation from non‐cephalic to cephalic presentation.At the 36‐week scan, fetal presentation was cephalic in 101 664 (94.2%) pregnancies and either breech, transverse or oblique in 6211 (5.8%). In 0.3% of cases with cephalic presentation at the 36‐week scan, there was subsequent spontaneous rotation to non‐cephalic presentation, and in half of these, the diagnosis was made during labor or at birth. ECV was attempted in 1584/6211 (25.5%) pregnancies with non‐cephalic presentation at the 36‐week scan and was successful in only 44.1% of cases. In the remaining 74.5% of cases, ECV was not attempted because of any of the following reasons: ECV was declined; Cesarean section was planned for a reason other than abnormal presentation; ECV was planned for the subsequent 1–2 weeks but, in the meantime, there was spontaneous rotation to cephalic presentation; or there was spontaneous onset of labor or rupture of membranes before planned ECV. In 5513/6211 (88.8%) pregnancies with non‐cephalic presentation at the 36‐week scan, ECV was not attempted or was unsuccessful, and in 37.7% of these, there was subsequent spontaneous rotation to cephalic presentation. Among the 6211 pregnancies with non‐cephalic presentation at the 36‐week scan, the presentation at birth was cephalic in 43.8%; in 74.8%, this was due to spontaneous rotation, and in 25.2%, it was due to successful ECV. Multivariable analysis demonstrated that the likelihood of non‐cephalic presentation at the 36‐week scan, that of successful ECV and that of spontaneous rotation from non‐cephalic to cephalic presentation was affected by several maternal and pregnancy characteristics, but the predictive performance for these events was poor, with the area under the receiver‐operating‐characteristics curve ranging from 0.608 to 0.717 and the detection rate at a 10% false‐positive rate ranging from 19.0% to 33.7%.Routine ultrasound examination at 35 + 0 to 36 + 6 weeks' gestation could improve pregnancy outcome by substantially reducing the risk of unexpected abnormal presentation in labor. However, an additional ultrasound scan for fetal presentation should be considered in all women when they present in labor. © 2024 The Author(s).

Objective: This study was designed to investigate the effects of hypertensive disorders of pregnancy (HDP) on the complications in very low birth weight (VLBW) neonates. Methods: We retrospectively included VLBW neonates (<37 weeks) who were delivered by HDP pregnant women with a body weight of < 1,500 g (HDP group) hospitalized in our hospital between January 2016 and July 2021. Gestational age matched VLBW neonates delivered by pregnant women with a normal blood pressure, with a proportion of 1:1 to the HDP group in number, served as normal control. Results: Then we compared the peripartum data and major complications between HDP group and control. The body weight, prelabor rupture of membrane (PROM), maternal age, cesarean section rate, fetal distress, small for gestational age (SGA), mechanical ventilation, RDS, necrotizing enterocolitis (NEC) (≥2 stage), Apgar score at 1 min, and mortality in HDP group showed statistical differences compared with those of the control (all p < 0.05). To compare the major complications among HDP subgroups, we classified the VLBW neonates of the HDP group into three subgroups including gestational hypertension group (n = 72), pre-eclampsia (PE) group (n = 222), and eclampsia group (n = 14), which showed significant differences in the fetal distress, Apgar score at 1 min, SGA, ventilation, RDS and NEC (≥2 stage) among these subgroups (all p < 0.05). Multivariate regression analysis showed that eclampsia and PE were the independent risk factors for SGA and NEC, respectively. Conclusion: HDP was associated with increased incidence of neonatal asphyxia, fatal distress, SGA, mechanical ventilation, RDS, NEC and mortality. Besides, eclampsia and PE were independent risk factors for SGA and NEC. [ABSTRACT FROM AUTHOR]

Maternal smoking, including both traditional cigarettes and electronic ones, is a significant modifiable risk factor associated with adverse perinatal outcomes, especially in twin pregnancies. This narrative review aims to explore the impact of maternal smoking on obstetric and neonatal outcomes in twin pregnancies, which inherently carry a higher risk of complications. A literature search was conducted using the PubMed and EMBASE databases, selecting studies published between January 1994 and October 2024. The findings demonstrate a clear association between smoking and increased risks of preterm birth and fetal growth restriction (FGR) in twin pregnancies. These risks are exacerbated when smoking is combined with other factors, such as preeclampsia and elevated body mass index (BMI). Smoking was also associated with long-term post-natal complications, including respiratory problems like asthma, as well as cognitive and behavioral disorders. However, an association with preeclampsia was not found, and further studies are needed to clarify the relationship in the fields of preterm premature rupture of membranes (PPROM) and fetal death. The adverse effects of smoking are primarily due to reduced oxygen supply to the fetus, caused by nicotine-induced vasoconstriction and carbon monoxide exposure, leading to placental insufficiency and fetal hypoxia. These effects are amplified in twin pregnancies due to the increased physiological demands. The review highlights that smoking cessation interventions during pregnancy are crucial to mitigate these risks and improve maternal and neonatal health outcomes. [ABSTRACT FROM AUTHOR]

Background: This study aimed to determine the differences in the cervical load and prevalence of Lactobacillus crispatus DNA, Lactobacillus iners DNA, Gardnerella vaginalis DNA, Sneathia sanguinegens DNA, and Ureaplasma species DNA between pregnant women with preterm prelabor rupture of membranes (PPROM) with and without a history of cervical excisional treatment. We also assessed the changes in the cervical load and prevalence of L. crispatus DNA, L. iners DNA, G. vaginalis DNA, S. sanguinegens DNA, and U. spp DNA. according to the cone length. Methods: This retrospective study included 132 women with singleton pregnancies complicated by PPROM. For all women, information about the cervical loads of bacterial DNA corresponding to L. crispatus, L. iners, G. vaginalis, S. sanguinegens, and U. spp., which was assessed using PCR, was available. Results: Women with a history of cervical excisional treatment had a higher cervical load of L. iners DNA (4.4 × 106 copies DNA/mL vs. 3.5 × 105 copies DNA/mL, p =.04) and a higher load and prevalence of U. spp. DNA (1.1 × 105 copies DNA/mL vs. 9.6 × 104 copies DNA/mL, p =.03; 2.7% vs. 0.5%, p =.04) than those without a history of cervical excisional treatment. In the subset of women with a history of cervical excisional treatment, those with a cone length 18 mm and more had a lower relative abundance of L. crispatus DNA (6% vs. 89%, p =.02), a higher load and relative abundance of L. iners DNA (1.1 × 107 copies DNA/mL vs. 8.2 × 105 copies DNA/mL, p =.04; 91% vs. 35%, p =.04), and higher loads of G. vaginalis DNA (7.6 × 104 copies DNA/mL vs. 3.2 × 102 copies DNA/mL, p =.02) than those with cone length < 18 mm. Conclusions: A history of cervical excisional treatment was associated with alterations in the cervical microbiota composition in pregnant women with PPROM. [ABSTRACT FROM AUTHOR]

Introduction: Intraamniotic infection (IAI) and subsequent early-onset neonatal sepsis (EONS) are among the main complications associated with preterm prelabor rupture of membranes (PPROM). Currently used diagnostic tools have been shown to have poor diagnostic performance for IAI. This study aimed to investigate whether the exposure to IAI before delivery is associated with short-term variation of the fetal heart rate in pregnancies with PPROM. Methods: Observational cohort study of 678 pregnancies with PPROM, delivering between 24 + 0 and 33 + 6 gestational weeks from 2012 to 2019 in five labor units in Stockholm County, Sweden. Electronic medical records were examined to obtain background and exposure data. For the exposure IAI, we used the later diagnosis of EONS in the offspring as a proxy. EONS is strongly associated to IAI and was considered a better proxy for IAI than the histological diagnosis of acute chorioamnionitis, since acute chorioamnionitis can be observed in the absence of both positive microbiology and biochemical markers for inflammation. Cardiotocography traces were analyzed by a computerized algorithm for short-term variation of the fetal heart rate, which was the main outcome measure. Results: Twenty-seven pregnancies were categorized as having an IAI, based on the proxy diagnosis of EONS after birth. Fetuses exposed to IAI had significantly lower short-term variation values in the last cardiotocography trace before birth than fetuses who were not exposed (5.25 vs 6.62 ms; unadjusted difference: −1.37, p = 0.009). After adjustment for smoking and diabetes, this difference remained significant. IAI with a later positive blood culture in the neonate (n = 12) showed an even larger absolute difference in STV (−1.65; p = 0.034), with a relative decrease of 23.5%. Conclusion: In pregnancies with PPROM, fetuses exposed to IAI with EONS as a proxy have lower short-term variation of the fetal heart rate than fetuses who are not exposed. Short-term variation might be useful as adjunct surveillance in pregnancies with PPROM. [ABSTRACT FROM AUTHOR]

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 FROM AUTHOR]

• Cervical incompetence remains associated with a high risk of preterm delivery and perinatal loss. • There are discrepancies in the factors identified as predictive of success or failure of emergency cerclage. • Due to the diversity of its eligibility criteria, it appears impossible to set a universal predictive score to assess its probability of success. • External validation for predictive scores is necessary to insure its pertinence in diverse clinical settings. Emergency cervical cerclage is a high-risk surgical procedure associated with maternal and fetal risks, including preterm birth. Authors have developed scores to try to predict the probability of success following emergency cerclage, but these tools have yet to be externally validated. Our main objective was to assess the preterm birth rate before 32 weeks following emergency cerclage. Secondary objectives included assessing perinatal outcomes and the predictive validity of two published scores in our setting. We hypothesized that predictive scores, such as Fuchs and Kokia scores, may not perform optimally in our population due to variability in clinical and biological characteristics that influence eligibility for cerclage across different settings. We conducted a retrospective, monocentric study in a tertiary maternity hospital. All patients who underwent emergency cerclage between January 1st, 2010, and December 31st, 2021, were included. The main outcome was preterm birth rate before 32 weeks. Secondary outcomes were need for maternal hospitalization after initial hospitalization for cerclage, preterm premature rupture of membrane, and perinatal death. The rate of preterm birth before 32 weeks and adverse perinatal outcomes were estimated. To assess the predictive validity of Fuchs' score in our population, we performed a multivariable logistic regression model including the score's variables and constructed receiver operating characteristic (ROC) curve. To assess the validity of Kokia's score in our population, we studied the correlation between the initial score and gestational age at delivery using Pearson's correlation coefficient. Our population was composed of 64 women who underwent an emergency cerclage. The median gestational age at delivery was 30.6 weeks (IQR (24.2; 37.6)). The preterm birth rate before 32 weeks was 54.7 %. The rate of perinatal death was 30.7 %. There were no statistical differences between the patients delivered before and after 32 weeks. The multivariable logistic regression model showed that none of the variables of Fuchs's score were significantly associated with preterm birth risk in our population. The AUC of the ROC curve using Fuchs' score was 0.63. There was a minor yet significant correlation between Kokia's score and gestational age at delivery (r = 0.26 – p = 0.04). Our study underscores the persistent risks associated with cervical insufficiency, including very preterm birth. It highlights the variability in performance of predictive scores across different populations, underscoring the need for external validation in diverse clinical settings. [ABSTRACT FROM AUTHOR]

• PROM before 26 weeks in twin pregnancies is associated with a 20.9% rate of spontaneous miscarriage or fetal demise and a 71.6% live birth rate of at least one twin in pregnancies not undergoing TOP, with a mean latency between PROM and delivery of 5.4 weeks. • The rate of sTOP due to PROM was about 25%, with this subset of pregnancies associated with a significantly lower rate of fetal demise and a significantly longer latency between PROM and delivery. • This meta -analysis might help maternal-fetal specialists in their daily clinical practice to offer the best state-of-the-art knowledge to the patients. To investigate the rate of obstetric and perinatal outcomes of premature rupture of membranes (PROM) occurring before 26 weeks in twin pregnancies. Medline, Embase, Cinahl and Web of Science databases were searched electronically up to January 2024. The selection criteria included both prospective and retrospective studies of twin pregnancies with PROM before 26 weeks of gestation. Case reports, case series with fewer than 5 cases, review articles, letters to the editor and editorials were excluded. Studies including both singletons and twin pregnancies were also excluded. We used meta -analyses of proportions to combine data and assess the pooled proportions. We used a random-effect model to perform the pooled data analyses. The study was registered with the PROSPERO database (CRD 42022368057). Quality assessment of the included studies was performed using the Newcastle-Ottawa Scale for cohort studies. Eight studies including 227 twin pregnancies were included in the analysis. The pooled proportion of termination of pregnancy (TOP) was 4.6 % (95 % CI 1.5–13.4), while the rate of selective TOP (sTOP) was 24.5 % (95 % CI 7.1–57.7). After the exclusion of cases of TOP, the overall rate of spontaneous miscarriage or fetal demise was 20.9 % (95 % CI 11.1–35.8), whereas the live birth rate of at least one twin was 71.6 % (95 % CI 61.2–80.1) of the ongoing pregnancies. The mean gestational age at delivery was 26.5 (95 % CI 25.1–28.0) weeks and the mean latency between PROM and delivery was 5.4 weeks (95 % CI 4.8–5.9) in all cases including those with fetal deaths. Neonatal outcomes showed that the overall neonatal mortality was 26.4 % (95 % CI 16.7–39.2). When focusing only on pregnancies undergoing sTOP, the observed livebirth rate was 87.7 %. The gestational age at rupture of membranes in these cases was 16.8 (95 % CI 14.9–18.6) weeks and the latency between PROM and delivery was significantly longer (19.9 (95 % CI 18.0–21.7) weeks) than that observed in unterminated pregnancies, with a mean gestational age at delivery nearly in the range of term (36.9 weeks). PROM in twins before 26 weeks is associated with overall high rates of adverse obstetric and neonatal outcomes, and it represents a clinical challenge for both counseling and management. Larger prospective studies unified objective protocols in terms of antenatal surveillance and management are needed. [ABSTRACT FROM AUTHOR]

Aim: The objective of this study is to perform a comprehensive assessment of fetal and perinatal results in pregnant women diagnosed with threatened miscarriage during the early trimester, and to evaluate the potential impact of this condition on the progression of pregnancy. Materials and Methods: In this retrospective study, the study group consisted of 200 patients who were diagnosed with threatened miscarriage and gave birth, while the control group was composed of 200 patients who gave birth without experiencing threatened miscarriage during the same period. The following variables were evaluated: age, gravida, parity, gestational week, and body mass index, as well as fetal and maternal perinatal outcomes. Results: The analysis of the delivery parameters revealed no statistically significant difference between the groups in terms of mode of delivery (p=1.000). The prevalence of preterm birth and preterm premature rupture of membranes (PPROM) was significantly higher in the case group compared to the control group (p < 0.001). No statistically significant difference was observed between the threatened miscarriage group and the control group in terms of the incidence of gestational diabetes, preeclampsia, placenta previa, abruptio placenta, macrosomia and stillbirth (p>0.05). Conclusions: In pregnant women with threatened miscarriage, the risk of preterm birth and preterm premature rupture of membranes (PPROM) is significantly higher. This finding emphasizes the need for careful monitoring and management of these patients, particularly concerning complications such as preterm birth and PPROM. [ABSTRACT FROM AUTHOR]

To determine whether polycystic ovary syndrome (PCOS) increases adverse pregnancy and birth outcomes in women undergoing frozen embryo transfer (FET). Retrospective cohort study. The PCOS group was matched 1:2 with the control group population using propensity score matching. Not applicable. During an 8-year period, 2,955 patients aged 20–40 years who underwent FET and delivered between January 2015 and December 2022 at the Reproductive Medical Center of Ruijin Hospital were evaluated for adverse pregnancy outcomes. None. All patients were assessed for specific pregnancy complications and birth outcomes, with a sub-group analysis conducted to compare patients with PCOS with and without hyperandrogenism. Women with PCOS demonstrated higher rates of gestational diabetes mellitus (24.9% vs. 16.4%; relative risk [RR], 1.51; 95% confidence interval [CI], 1.26–1.82; P <.001), gestational hypertension (12.2% vs. 8.9%; RR, 1.37; 95% CI, 1.05–1.80; P =.022), preterm prelabor rupture of membranes (7.0% vs. 3.6%; RR, 1.92; 95% CI, 1.29–2.86; P =.001), cervical length shortening (1.8% vs. 0.4%; RR, 8.39; 95% CI, 1.56–12.49; P =.002), large-for-gestational age (17.4% vs. 13.7%; RR, 1.27; 95% CI, 1.02–1.57; P =.032), and low birth weight (19.9% vs. 16.0%; RR, 1.25; 95% CI, 1.02–1.52; P =.030) in overall propensity score matching analysis. Newborns of patients with PCOS had a higher risk of preterm birth <37 weeks (10.5% vs. 6.6%; RR, 1.59; 95% CI, 1.12–2.26; P =.009) in singleton pregnancies. Patients with PCOS with hyperandrogenism showed a higher incidence of cervical length shortening (5.5% vs. 0.5%; adjusted odds ratio, 15.62; 95% CI, 2.25–108.48; P =.005) compared with those without, after adjusting for relevant confounders. Polycystic ovary syndrome increases the incidence of adverse pregnancy outcomes after FET cycles. Our study suggests women with PCOS may warrant further monitoring and additional counseling before and during pregnancy. [ABSTRACT FROM AUTHOR]

Objective: To utilise combined diffusion‐relaxation MRI techniques to interrogate antenatal changes in the placenta prior to extreme preterm birth among both women with PPROM and membranes intact, and compare this to a control group who subsequently delivered at term. Design: Observational study. Setting: Tertiary Obstetric Unit, London, UK. Population: Cases: pregnant women who subsequently spontaneously delivered a singleton pregnancy prior to 32 weeks' gestation without any other obstetric complications. Controls: pregnant women who delivered an uncomplicated pregnancy at term. Methods: All women consented to an MRI examination. A combined diffusion‐relaxation MRI of the placenta was undertaken and analysed using fractional anisotropy, a combined T2*‐apparent diffusion coefficient model and a combined T2*‐intravoxel incoherent motion model, in order to provide a detailed placental phenotype associated with preterm birth. Subgroup analyses based on whether women in the case group had PPROM or intact membranes at time of scan, and on latency to delivery were performed. Main Outcome Measures: Fractional anisotropy, apparent diffusion coefficients and T2* placental values, from two models including a combined T2*‐IVIM model separating fast‐ and slow‐flowing (perfusing and diffusing) compartments. Results: This study included 23 women who delivered preterm and 52 women who delivered at term. Placental T2* was lower in the T2*‐apparent diffusion coefficient model (p < 0.001) and in the fast‐ and slow‐flowing compartments (p = 0.001 and p < 0.001) of the T2*‐IVIM model. This reached a higher level of significance in the preterm prelabour rupture of the membranes group than in the membranes intact group. There was a reduced perfusion fraction among the cases with impending delivery. Conclusions: Placental diffusion‐relaxation reveals significant changes in the placenta prior to preterm birth with greater effect noted in cases of preterm prelabour rupture of the membranes. Application of this technique may allow clinically valuable interrogation of histopathological changes before preterm birth. In turn, this could facilitate more accurate antenatal prediction of preterm chorioamnionitis and so aid decisions around the safest time of delivery. Furthermore, this technique provides a research tool to improve understanding of the pathological mechanisms associated with preterm birth in vivo. [ABSTRACT FROM AUTHOR]

Objectives: This study aims to elucidate the expression patterns of LGALS1 (galectin-1) and LGALS9 (galectin-9) genes in placental tissues of pregnancies affected by preterm prelabor rupture of membranes (PPROM). The overarching goal is to understand the potential roles of these galectins in the pathophysiology of PPROM, particularly in maternal-fetal immune tolerance and placental development. Material and methods: Conducted as a prospective, single-center study at the Gynecology and Obstetrics Clinical Hospital in Poznan, Poland, from June 2021 to May 2023, the research involved 25 participants, including 12 with PPROM and 13 healthy controls. Placental tissues were obtained, and RNA extraction was performed. Galectin gene expression (LGALS1 and LGALS9) was analyzed using quantitative real-time PCR. Demographic and clinical data were collected, and statistical analyses were employed to assess correlations between galectin expression and clinical parameters. Results: While significant differences were observed in gestational age at delivery and birth weight between the PPROM and control groups, the expression levels of LGALS1 and LGALS9 did not show statistically significant variations. Correlation analyses revealed no significant associations between galectin expression and various clinical parameters. Conclusions: Contrary to the hypothesis, this study did not identify significant alterations in galectin-1 and galectin-9 expression in placentas affected by PPROM. Despite the limitations of a small sample size, these findings provide initial insights into the potential roles of galectins in PPROM. Further research on larger cohorts is warranted to comprehensively understand the implications of galectin involvement in the pathophysiology of PPROM. [ABSTRACT FROM AUTHOR]

Objectives: Genitourinary tract infections in pregnant women are one of the causes of abnormal pregnancy development including miscarriages, premature labor or premature rupture of membranes (PPROM). Atypical bacteria responsible for reproductive tract infections include Mycoplasma genitalium, Mycoplasma hominis, Ureaplasma urealyticum and Ureaplasma parvum. Identification of pathogens and appropriately selected therapy can improve obstetric outcomes in patients with symptoms of threatened miscarriage or threatened preterm labor. The purpose of our study is to analyze the impact of reproductive tract infections with Ureaplasma and Mycoplasma bacteria during pregnancy. Material and methods: In the presented study, we retrospectively analyzed the cases of 201 pregnant patients hospitalized in the Obstetrics and Gynecology Department of Poznan Regional Hospital in 2019-2022, who had a swab taken from external os area of the cervix for atypical bacteria -- Ureaplasma and Mycoplasma. Only patients with symptoms of threatened miscarriage or threatened preterm labor were included in the study group. Microbiological tests were performed in the hospital laboratory with the Mycoplasma IST 3 test from Biomerieux. Results: We found a higher incidence of preterm labor in patients with symptoms of threatened preterm labor and a genital tract infection with Ureaplasma/Mycoplasma bacteria, compared to patients not infected with Mycoplasma/Ureaplasma -- 31.1% vs 20% (p = 0.098). This observation in the case of Ureaplasma/Mycoplasma monoinfection group applied to 6 patients. This observation in the case of Ureaplasma/Mycoplasma monoinfection group applied to 6 patients -- 75% of the group. Pregnant patients who had co-infection with other types of bacteria (48 patients in total) gave birth before 37 weeks of pregnancy in 27.1% of cases. We obtained a significant difference (p = 0.007) when comparing groups with positive and negative cultures for Ureaplasma/Mycoplasma by the presence of monoinfection/coinfection and the week of pregnancy in which delivery occurred. We also noted the effect of atypical bacterial infection for PPROM -- this complication preceded preterm delivery in 40% of ureaplasma-positive patients, compared to 20% of PPROM without infection. We found a similar rate of preterm labor and pregnancy loss in Ureaplasma/Mycoplasma-positive patients who received antibiotic therapy (35.7%) compared to a group of pregnant women who did not receive treatment (31.6%). Conclusions: Infection of the genital tract with atypical bacteria Ureaplasma and Mycoplasma has a negative impact on the course of pregnancy. Identification of the type of microorganisms in cervical canal secretions of pregnant patients with symptoms of threatened miscarriage or preterm labor seems crucial. The impact of antibiotic therapy though, requires further analysis. [ABSTRACT FROM AUTHOR]

Background: Suspected preterm labour (PTL) and prelabour rupture of membranes (PPROM) are common indications for aeromedical retrieval in the Top End, Northern Territory, Australia, where many women reside remotely and preterm birth (< 37 completed weeks of gestation) is common. The primary objective of this study was to determine rate of delivery during the index admission following aeromedical transfers from remote clinics to Royal Darwin Hospital for suspected PTL/PPROM. Methods: A retrospective cohort study of aeromedical transfers for suspected PTL/PPROM from 1 January 2020 to 31 July 2022 was undertaken. Transfers were identified through CareFlight, the regional air ambulance service, and complemented with data from hospital records. Clinical and sociodemographic characteristics were compared by delivery status during the index (post-retrieval) admission using parametric and non-parametric tests and multivariable linear regression analysis. Results: 238 women with singleton pregnancies were retrieved for suspected PPROM (n = 77, 32.4%) or PTL (n = 161, 67.6%), together accounting for 49.2% of all obstetric transfers (n = 483). Of 77 patients transferred for suspected PPROM, 47 (61.0%) had ruptured membranes confirmed on arrival, and 45 (95.7%) of them delivered during the index admission. None of the 30 women transferred for suspected PPROM with intact membranes on arrival delivered during the index admission. Of 161 patients transferred for suspected PTL, 13 (8.1%) had ruptured membranes confirmed on arrival, and 12 (92.3%) of them delivered during the index admission. Amongst women transferred for suspected PTL with intact membranes confirmed on arrival, 14.9% (22/149) delivered during the index admission. Prior to arrival, 120 women (50.4%) had a documented speculum examination, and 15 (6.3%) and 9 (3.8%) had cervicovaginal swab tests to assess their risks of a PPROM and PTL, respectively. Half of women who did not deliver during the index admission had received antenatal corticosteroids (n = 76). Conclusions: Many aeromedical retrievals for suspected PTL/PPROM did not result in delivery during the index admission. Women retrieved for suspected PPROM with intact membranes on arrival were less likely to deliver. Upskilling remote clinic staff and better point-of-care testing may reduce retrievals and unnecessary interventions. Prospective cohort studies designed to enable accurate prediction of which cases can be safely not retrieved are required. Trial registration: Not applicable. [ABSTRACT FROM AUTHOR]

Background: There is an unmet need for a large comprehensive population-based dataset documenting national birthing trends in China and a partograph specifically tailored to Chinese women. This study assessed the impact of using the World Health Organization (WHO) partograph or Zhang's guideline to manage labor and delivery in China and inform the development of a partograph that specifically aligns with the progression of labor in Chinese women. Methods: This retrospective analysis included low-risk nulliparous women with a singleton, full-term fetus in cephalic presentation entering spontaneous labor at a specialized obstetric hospital in China between January 2010 and June 2022. Pregnant women were managed according to the WHO partograph (January 2010-August 2014, n = 31,286) or Zhang's guideline (September 2014-June 2022, n = 49,821). Results: Rates of assisted reproduction (4.57% vs. 1.05%; p < 0.0001) and hypertension (7.44% vs. 6.71%; p < 0.0001) were significantly higher for pregnant women managed according to Zhang's guideline compared to the WHO partograph. Rates of labor intervention (35.31% vs. 13.95%; p < 0.0001), including induction of labor by oxytocin, artificial rupture of membranes, lateral episiotomy and conversion to cesarean section (all, p < 0.0001), were significantly higher for pregnant women managed according to the WHO partograph. Rates of forceps assisted vaginal deliveries (12.67% vs. 6.42%; p < 0.0001) and postpartum hemorrhage (10.9% vs. 6.2%; p < 0.0001) were significantly higher, and birth asphyxia (0.15% vs. 0.09%; p = 0.02) was significantly lower, for pregnant women managed according to Zhang's guideline. Conclusions: This study provides valuable insights into the utilization of the WHO partograph and Zhang's guideline in managing labor and delivery among Chinese women. Findings indicate that women managed according to Zhang's guideline had higher rates of assisted reproduction and hypertension, suggesting a potentially different demographic profile or underlying health conditions compared to women managed according to the WHO partograph. Notably, the use of the WHO partograph was linked to a significant increase in labor interventions, while Zhang's guideline resulted in higher rates of forceps-assisted vaginal deliveries and postpartum hemorrhage, yet interestingly, a lower incidence of birth asphyxia. These contrasting outcomes underscore the importance of aligning labor management tools with the specific needs and progression of labor in Chinese women. The results advocate for a tailored partograph that could better reflect the unique characteristics of Chinese women and optimize decision making and maternal and neonatal outcomes.

To prospectively validate the diagnostic performance of a non-invasive point-of-care tool (Rapid IAI System), including vaginal alpha-fetoprotein and interleukin-6, to predict the occurrence of intra-amniotic inflammation in a Spanish cohort of patients admitted with a diagnosis of preterm labor and intact membranes.From 2017 to 2022, we prospectively evaluated a cohort of pregnant women diagnosed with preterm labor and intact membranes admitted below 34+0 weeks who underwent amniocentesis to rule-in/out intra-amniotic infection and/or inflammation. Vaginal sampling was performed at the time of amniocentesis or within 24–48 h. Amniotic fluid IL-6, vaginal alpha-fetoprotein and vaginal IL-6 concentrations were measured using a point-of-care tool provided by Hologic Inc., “Rapid IAI System”. We defined intra-amniotic inflammation when amniotic fluid IL-6 values were greater than 11.3 ng/mL. During recruitment, clinicians were blinded to the results of the point-of-care tool. The original prediction model proposed by Hologic Inc. to predict intra-amniotic inflammation was validated in this cohort of patients.We included 151 patients diagnosed with preterm labor and intact membranes. Among these, 29 (19.2 %) had intra-amniotic inflammation. The algorithm including vaginal IL-6 and alpha-fetoprotein showed an area under curve to predict intra-amniotic inflammation of 80.3 % (±5.3 %) with a sensitivity of 72.4 %, specificity of 84.6 %, positive predictive valuve (PPV) of 52.5 %, negative predictive value (NPV) of 92.9 %, and a positive likelihood ratio (LR+) of 4.6 and negative likelihood ratio (LR−) of 0.33.External validation of a non-invasive rapid point-of-care tool, including vaginal alpha-fetoprotein and IL-6, showed very good diagnostic performance for predicting the absence of intra-amniotic inflammation in women with preterm labor and intact membranes.

Background: Prior research showed that elevated serum uric acid (SUA) levels in women with polycystic ovary syndrome (PCOS) before in vitro fertilization or intracytoplasmic sperm injection (IVF/ICSI) treatment can lead to a lower rate of live birth and an increased risk for low birthweight. Nonetheless, it is not known whether elevated SUA results in similar reproductive outcome in women without PCOS. This study aimed to exploring the relationship between pre-pregnancy SUA levels and reproductive outcomes in non-PCOS women undergoing IVF/ICSI treatment. Methods: This single-center, retrospective study included 13,325 women without PCOS undergoing their first IVF/ICSI fresh embryo transfer cycles from January 2014 to December 2022 at a university-affiliated reproductive medicine center in China. The trends for pregnancy, obstetric and perinatal outcomes across quartiles of SUA levels were assessed. A logistic regression analysis was applied to control for baseline and cycle characteristics. Generalized addition model was used to draw spline smoothing plot. Results: There was no significant decreasing or increasing trend in the clinical pregnancy rate and live birth rate with the increase in quartiles of SUA levels. For Obstetric and perinatal outcomes following a single live birth, the percentage of hypertensive disorders in pregnancy (1.6–4.1%, Ptrend<0.001), gestational diabetes mellitus (5.9–13.9%, Ptrend<0.001), premature rupture of membranes (0.6–1.5%, Ptrend=0.016), preterm birth (6.3–9.2%, Ptrend=0.009), macrosomia (2.3–5.5%, Ptrend<0.001), large for gestational age (10.8–14.9%, Ptrend=0.002) all increased significantly from the lowest quartile to the highest. Logistic regression results showed that compared with those in quartile 1, the risk of maternal and infant complications mentioned above was still significantly higher in quartile 4 after adjusting for reproductive related factors. When further confounding factors were added, including body mass index (BMI), blood pressure, fasting blood glucose, and blood lipids related indicators, only gestational diabetes mellitus and macrosomia showed a significant increase. Conclusion: In women without PCOS, SUA levels before IVF/ICSI treatment do not affect the probabilities of clinical pregnancy and live birth. An elevated SUA level is associated with an increased risk for hypertensive disorders in pregnancy, gestational diabetes mellitus, premature rupture of membranes, preterm birth, macrosomia, and large for gestational age. For gestational diabetes mellitus and macrosomia, the association is independent of BMI, blood pressure, blood glucose, and blood lipid. [ABSTRACT FROM AUTHOR]

Background/Objectives: Multidrug-resistant urinary tract infections (MDR UTIs) constitute an important public health problem, especially in pregnant patients. The aim of this retrospective study was to characterize the bacterial spectrum and the profile of microbial resistance in cases of UTIs occurring in pregnant women, as well as their impact on obstetrical and neonatal outcomes. Methods: A total of 371 pregnant patients with UTIs were included in the analysis and were segregated into the following groups based on the type of bacterial resistance to antibiotics: MDR UTIs (70 patients, group 1), UTIs resistant to one class of antibiotics (108 patients, group 2), UTIs resistant to two classes of antibiotics (102 patients, group 3), and sensitive UTIs (91 patients, group 4). We used descriptive statistics for characterizing and comparing the microbial spectrum and the clinical characteristics of the patients. A multinomial logistic regression model for evaluating the relationship between the type of urinary tract infection and adverse obstetric or neonatal outcomes was employed. Results: In the case of MDR UTIs, the bacterial spectrum mainly included Escherichia coli, Enterococcus faecalis, and Klebsiella species. We found almost universal resistance to ampicillin. Our data confirmed an increased risk of preterm birth, premature rupture of membranes, neonatal respiratory distress syndrome, and neonatal intensive care unit admission for patients with MDR infections. Conclusions: The increased incidence of pathogens resistant to commonly used antibiotic classes in pregnancy suggests the need for the development of local and national protocols that adapt therapeutic and prophylactic regimens to clinical realities.

Introduction: Ethiopia is one of the countries where persistently high neonatal and maternal mortalities are reported. Preterm prelabor rupture of membrane (PPROM) plays an important contribution to these high mortalities. However, there is a paucity of comprehensive evidence about the epidemiology of PPROM in Ethiopia. Therefore, this systematic review was conducted to assess the pooled prevalence and determinants of PPROM among pregnant women in Ethiopia. Methods: A systematic review and meta-analysis were conducted following the PRISMA guideline. Relevant literatures were searched on African Journals Online (AJOL), PubMed, Scopus, Epistemonikos, CINAHL, Cochrane Library and gray literature. All statistical analyses were performed using STATA 17 software. The random effect meta-analysis model was employed to summarize the pooled estimates. Heterogeneity between included studies was evaluated using I2 statistic. Egger's regression test and Begg's correlation test were employed to assess publication bias, in conjunction with funnel plot. Besides, the non-parametric trim-and-fill analysis, sensitivity analysis, subgroup analysis and meta-regression were also performed. Results: A total of 13 original studies with 24,386 participants were considered in this systematic review. The pooled prevalence of PPROM was 6.58% (95% CI: 5.36, 7.79). Urinary tract infection (OR: 3.44; 95% CI: 1.81, 6.53), abnormal vaginal discharge (OR: 4.78; 95% CI: 2.85, 8.01), vaginal bleeding (OR: 2.04; 95% CI: 1.03, 4.06), history of PROM (OR: 4.64; 95% CI: 2.71, 7.95), history of abortion (OR: 3.06; 95% CI: 1.71, 5.46), malnutrition (OR: 5.24; 95% CI: 2.63, 10.44), anemia (OR: 3.97; 95% CI: 2.01, 7.85) and gestational diabetes (OR: 5.08; 95% CI: 1.93, 13.36) were significantly associated with PPROM. Conclusion: This meta-analysis found a high prevalence of PPROM in Ethiopia. Urinary tract infection, abnormal vaginal discharge, vaginal bleeding, history of PROM, history of abortion, malnutrition, anemia and gestational diabetes were risk factors for PPROM. Prevention and control of antenatal infections and malnutrition are highly recommended to reduce the magnitude of PPROM in Ethiopia. Additionally, healthcare providers should emphasize the identified risk factors. Protocol registration number: CRD42024536647. [ABSTRACT FROM AUTHOR]

ABSTRACT Background Aim Data Sources Study Eligibility Criteria Methods Results Conclusion Little scientific evidence exists on maternal and fetal outcomes in aplastic anemia (AA) during pregnancy.The review was conducted to assess the maternal and fetal outcomes due to AA during pregnancy.Web of Science, EMBASE, PubMed, Scopus, Cochrane CENTRAL, and registries until May 5, 2024.Studies (prospective, retrospective cohort, cross‐sectional, one arm, survey, follow‐up studies) evaluating AA during pregnancy were searched as per PROSPERO registered protocol (CRD42024506668). Case reports, case series, expert opinion letters, and studies assessing less than or equal to 10 pregnant women were not considered. The primary outcome was the prevalence of preeclampsia in AA pregnancies. The secondary outcomes included spontaneous abortion, preterm premature rupture of membranes, premature rupture of membranes, fetal growth restriction, type of delivery, intrauterine fetal death, maternal and neonatal mortality, and pre and post‐pregnancy remission status comparison.The quality of research was checked using the New Castle‐Ottawa risk‐of‐bias tool. A meta‐analysis model with a random effect distribution, coupled with meta‐regression, sensitivity analysis, and publication bias assessment, was used in the statistical software R. Standard Equator network study reporting guidelines were followed.Seven (one prospective and six retrospective cohort) studies included patients with confirmed AA diagnosis in 248 pregnancies. The pooled prevalence of preeclampsia was 13% (95% CI, 8%–20%). Heterogeneity was low in the present meta‐analysis (I2 = 26%). The secondary outcome evaluation showed a pooled prevalence of 5% (95% CI, 3%–11%) for spontaneous abortion, 4% (95% CI, 1%–11%) for preterm premature rupture of membranes, 10% (95% CI, 3%–28%) for premature rupture of membranes, 6% (95% CI, 3%–11%) for fetal growth restriction, 5% (95% CI, 2%–13%) for intrauterine fetal death, 12% (95% CI, 5%–26%) for post‐partum hemorrhage, 74% (95% CI, 45%–91%) for intrapartum transfusion requirement, and 55% (95% CI, 27%–80%) for the cesarean delivery opting. The maternal mortality in pregnancies with AA was 4% (95% CI, 0.01–0.14), whereas neonatal mortality was 7% (95% CI, 0.03–0.18). The odds of AA complete remission were better in pre‐pregnancy than post‐pregnancy (OR = 0.36; 95% CI = 0.08–1.66), although the results remain insignificant. The leave‐one‐out sensitivity analysis did not change the pooled estimates for the primary outcome.A risk of developing preeclampsia was observed in every eighth pregnant woman with an AA diagnosis. AA remission status might worsen after undergoing pregnancy, considering the significant obstetric morbidity and mortality burden. [ABSTRACT FROM AUTHOR]

Introduction: To compare neonatal, obstetrical, and maternal outcomes associated with outpatient vs inpatient management of pregnancies with preterm prelabor rupture of membranes (PPROM). Material and Methods: A search of MEDLINE, EMBASE, the Cochrane Database and Central Register from January 1, 1990 to July 31, 2023 identified randomized controlled trials (RCTs) and cohort studies comparing outpatient with inpatient management for pregnant persons diagnosed with PPROM before 37 weeks' gestation. No language restriction was applied. We applied a random effects model for meta‐analysis. Trustworthiness was assessed using recently published guidance and Risk of bias using the RoB 2.0 tool for RCTs and ROBINS‐I tool for cohort studies. The Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) approach was used to assess the certainty of evidence (COE). Outcomes of interest included perinatal mortality, neonatal morbidities, latency and gestational age at delivery, and maternal morbidities. RCTs and cohort studies were analyzed separately. This study was registered in the International Prospective Register of Systematic Reviewsr: CRD42022295275. Results: From 2825 records, two RCTs and 10 cohort studies involving 1876 patients were included in the review and meta‐analysis. Outpatient management protocols varied but generally included brief initial hospitalization, strict eligibility criteria, and surveillance with laboratory and ultrasound investigations. Outpatient management showed lower rates of neonatal respiratory distress syndrome (cohort: RR 0.63 [0.52–0.77, very low COE]), longer latency to delivery (RCT: MD 7.43 days [1.14–13.72 days, moderate COE], cohort: MD 8.78 days [2.29–15.26 days, low COE]), higher gestational age at birth (cohort: MD 7.70 days [2.02–13.38 days, low COE]), lower rates of Apgar scores <7 at 5 min of life (cohort: RR 0.66 [0.50–0.89, very low COE]), and lower rates of histological chorioamnionitis (cohort: RR 0.74 [0.62–0.89, low COE]) without increased risks of adverse neonatal, obstetrical, or maternal outcomes. Conclusions: Meta‐analysis of data from RCTs and cohort studies with very low‐to‐moderate certainty of evidence indicates that further high‐quality research is needed to evaluate the safety and potential benefits of outpatient management for selected PPROM cases, given the moderate‐to‐high risk of bias in the included studies.

Introduction: Chorioamniotic membrane separation (CMS) is a known complication after fetal spina bifida (fSB) repair. This study's goal was to analyze women's outcomes with open fSB repair and CMS (group A) compared to the ones without (group B) and to assess the influence of CMS size and patient management. Methods: A total of 194 women with open fSB repair at our center were included in this retrospective study. Outcomes of group A were compared to the ones of group B. Regression analysis was performed to assess risk factors for CMS. Two subgroup analyses assessed the impact of CMS size (small [A-small] vs. large [A-large]) as well as patient management (A1 = hospitalization vs. A2 = no hospitalization) on pregnancy outcomes. Results: Of 194 women, 23 (11.9%) were in group A and 171 (88.1%) in group B. Preterm premature rupture of membranes (PPROMs) (69.6% vs. 24.1%, p = <0.001), amniotic infection syndrome (AIS) (22.7% vs. 7.1%, p = 0.03), histologically confirmed chorioamnionitis (hCA) (40.0% vs. 14.7%, p = 0.03), length of hospital stay (LOS) after fSB repair (35 [19–65] vs. 17 [14–27] days), and overall LOS (43 [33–71] vs. 35 [27–46] days, p = 0.004) were significantly more often/longer in group A. Gestational age (GA) at delivery was significantly lower in group A compared to group B (35.3 [32.3–36.3] vs. 36.7 [34.9–37.0] weeks, p = 0.006). Regression analysis did not identify risk factors for CMS. Subgroup analysis comparing CMS sized in group A-small versus A-large showed higher AIS rate (42% vs. 0%, p = 0.04), lower LOS (22.0 [15.5–42.5] vs. 59.6 ± 24.1, p = 0.003). Comparison of group A1 versus A2 showed longer LOS (49.3 ± 22.8 vs. 15 [15–17.5] days, p < 0.001), lower planned readmission rate (5.6% vs. 80%, p = 0.003). Conclusion: CMS significantly increased the risk of PPROM, AIS, hCA, caused longer LOS, and caused lower GA at delivery. Women with small CMS had higher AIS rates but shorter LOS compared to women with large CMS, while apart from LOS pregnancy outcomes did not differ regarding patient management (hospitalization after CMS yes vs. no).

Introduction: Limited data exist regarding outcomes when pre- and periviable PPROM (PPROM ≤26 weeks of gestation) occurs as a complication of fetoscopic laser surgery (FLS) for twin-twin transfusion syndrome (TTTS). Methods: This is a retrospective cohort study of FLS cases performed at a single institution between January 2015 and May 2021. Study inclusion was limited to patients with monochorionic-diamniotic twin pregnancies complicated by TTTS who underwent FLS. Patients were grouped by pPPROM status, and further stratified to those continuing with expectant management, and outcomes were compared between groups. The primary outcome was survival to live birth of at least one twin. Results: During the study period, 171 patients underwent FLS and a total of 96 (56.1%) subjects satisfied inclusion criteria. Among included subjects, 18 (18.8%) experienced pPPROM after FLS and 78 (81.2%) did not. Baseline characteristics were similar between groups. Among patients with pPPROM, 11 (61.1%) pursued expectant management and 7 (38.9%) opted for pregnancy termination. Among expectantly managed subjects, median pPPROM-to-delivery interval was 47.0 days (6.0–66.0 IQR) with a median gestational age at delivery of 29+1 weeks (24 + 4–33 + 6 IQR). Rates of survival to live birth of at least one twin (90.9% vs. 96.2% p = 0.42) were similar between those with pPPROM undergoing expectant management and those without pPPROM. Dual survivorship (45.5% vs. 78.2%, p = 0.03), perinatal survival to live birth (68.2% vs. 87.2%, p = 0.05), and perinatal survival to newborn hospital discharge (59.1% vs. 85.9%, p = <0.01) were all significantly lower among those with pPPROM. Gestational age at delivery was lower among those continuing with pregnancies complicated by pPPROM (29 + 1 vs. 32+5 weeks, p = <0.01). Conclusion: Survival of at least one twin to live birth remained high among those pursing expectant management after experiencing post-FLS pPPROM, suggesting that the outlook after this complication is not necessarily poor. However, this complication was associated with lower chances of dual survival and greater prematurity. Plain Language Summary: Prelabor premature rupture of membranes (PPROM) commonly occurs after fetoscopic laser surgery (FLS) and may occur in the gestational time period where survival to and beyond birth is precarious. In those that do experience pre or periviable PPROM, termination is offered, but for those who wish to continue the pregnancy, data on survival outcomes of at least one twin are limited. In this retrospective study, we aimed to determine the survival outcomes for patients who opted for expectant management following pre- or periviable PPROM after FLS at a single institution from Jan 2015 to May 2021. Of 96 included subjects, 18 experienced this complication and 11 of these opted to continue the pregnancy. We compared outcomes of these 11 patients with the 76 patients who did not experience pre or periviable PPROM. We found that expectantly managed pre- and periviable PPROM after FLS is associated with decreased gestational age at delivery and lower rates of dual survival when compared to similarly treated pregnancies unaffected by pre- and periviable PPROM. However, survival to live birth of at least one twin was similar between groups. [ABSTRACT FROM AUTHOR]

• The presence of CSS is associated with an increased risk of preterm delivery. • The use of ultrasound markers is cost effective and easy to reproduce. • The contribution of CSS to cervical length seems relatively limited. To investigate the contribution of the cervical sliding sign to conventional cervical length measurement in patients at risk of preterm labor. The study, performed as a prospective cohort study, included patients admitted to a tertiary research hospital with a diagnosis of threatened preterm labor. The participants were divided into two groups: those who gave birth before and after 37 weeks of gestation. The clinical and demographic characteristics, cervical length, presence of a short cervix (SC), and cervical sliding sign (CSS) were compared between the groups. Furthermore, correlation and regression analyses were conducted to investigate the relationship between the presence of a SC, the presence of CSS, and the coexistence of these two findings with preterm delivery, as well as the interval between the symptoms and delivery being less than four weeks. The study included 77 patients who delivered prematurely and 65 patients who delivered at term. The following variables were significantly lower in the preterm delivery group: cervical length, gestational age at delivery, neonatal weight, and time between the first examination and delivery (p = 0.003, <0.001, <0.001 and < 0.001, respectively). A higher percentage of women in the preterm delivery group exhibited a diagnosis of a SC, the presence of CSS, and the coexistence of both conditions (p = 0.002, 0.012 and 0.018, respectively). The results of the logistic regression analysis indicated that the odds ratios for preterm delivery were 3.3 in the presence of a SC alone, 2.67 in the presence of CSS alone, and 2.85 in the association of both findings (p = 0.003, 0.013 and 0.021 respectively). The odds ratios for delivery in less than four weeks were 3.08 in the presence of a SC alone, 3.4 in the presence of CSS alone, and 3.54 in the association of both findings (p = 0.004, 0.002 and 0.005 respectively). In singleton pregnant women presenting with threatened preterm labor, the presence of CSS is associated with an increased risk of preterm delivery and a decreased presentation-to-delivery interval. However, its contribution to conventional cervical length measurement appears to be relatively limited. [ABSTRACT FROM AUTHOR]

• Cervical length, advanced cervical dilatation and in vitro fertilization are predictors of cerclage failure. • Similar outcomes were registered for patients who underwent cervical cerclage before and after 24 weeks. • A positive vaginal swab before cerclage exposed patients to higher risks of preterm premature rupture of membranes and chorioamnionitis. • Pre-operative assessment of a local infectious/inflammatory process may provide further insights into the pathophysiological mechanisms behind cerclage failure. We aimed to retrospectively evaluate obstetric and neonatal outcomes in patients who underwent ultrasound-indicated and rescue cervical cerclage and to identify predictors for cerclage failure and consequent preterm birth (PTB). We conducted a retrospective analysis on singleton pregnancies between 16 and 27 weeks of gestation who presented with a transvaginal sonographic cervical length (TVS-CL) <25 mm and a previous PTB/second-trimester miscarriage or prolapsed amniotic membranes and/or a TVS-CL <15 mm and underwent cervical cerclage at Mangiagalli Center, Milan, between September 2011 and December 2021. Univariate and multivariate logistic regression analyses were used to identify possible predictive factors of cerclage failure. During the study period, a total of 136 singletons met the inclusion criteria. Overall, 3 % of pregnancies did not reach fetal viability, mostly due to post-cerclage preterm premature rupture of membranes and/or chorioamnionitis. The mean gestational age at delivery was 35.9 ± 4.5 weeks. Neonates were delivered beyond 37 weeks in 63.2 % of cases, between 28 and 37 weeks in 26.5 %, and less than 28 gestational weeks in 10.3 %. At the multivariate analysis, independent risk factors for miscarriage or PTB were cervical length <10 mm (odds ratio, OR 3.44), advanced cervical dilatation (OR 4.76), and in vitro fertilization (OR 4.66). A history of previous miscarriage, premature delivery, and uterine malformations did not increase the risk of post-cerclage delivery before 37 weeks. In the preterm delivery group, 14 % of patients experienced preterm premature rupture of membranes (pPROM) and 10 % had chorioamnionitis, while no case was registered in the term delivery group. A positive vaginal swab at the time of cervical cerclage was not significantly associated with PTB at the multivariate analysis but it emerged as a significant risk factor for both chorioamnionitis (OR 11.03) and pPROM (OR 5.28). Ultrasound-indicated and rescue cervical cerclage were effective in prolonging pregnancy, even when placed beyond 24 weeks of gestation. Preoperative cervical length of less than 10 mm, advanced dilatation, and in vitro fertilization are associated with an increased risk of cerclage failure. A positive vaginal swab before cerclage is associated with increased rates of intrauterine infectious-inflammatory processes. [ABSTRACT FROM AUTHOR]

Objective: Previous studies have indicated that there is an association between cervical cerclage and type of suture material. However, it is still unclear which suture material can provide the greatest benefit to patients who have undergone cerclage. This study investigated the effect of two different suture materials (Mersilene tape vs braided suture) used for transvaginal cervical cerclage placement on maternal outcomes of women with cervical insufficiency. Methods: In this retrospective case–control study, 170 women who underwent history‐, ultrasound‐, or physical examination‐indicated transvaginal cervical cerclage were categorized according to suture materials used for cerclage: a total of 96 received Mersilene tape and 74 received braided suture. Study participants received a transvaginal cervical cerclage before 28 weeks and were followed up until delivery to assess pregnancy and neonatal outcomes. The primary outcome was gestational age at delivery. Secondary outcomes included preterm premature rupture of membranes (PPROM), premature rupture of membranes (PROM), chorioamnionitis, neonatal survival rate, and neonatal morbidity. Results: Out of 170 eligible women, 74 (43.5%) received braided suture while 96 (56.5%) received Mersilene tape. Baseline characteristics were similar between the two groups. The group that received braided suture had a lower incidence of gestational age at delivery <37 weeks (29.2% vs 54.2%, P = 0.046), PPROM (9.5% vs 21.9%, P = 0.029) and PROM (17.6% vs 32.3%, P = 0.028) compared to the group that received Mersilene tape. However, there were no significant differences between the two groups in average gestational age at delivery, the rate of gestational age at delivery <24, <28, <32, and < 34 weeks, chorioamnionitis, and neonatal survival rate, as well as neonatal morbidity. Conclusion: Compared to Mersilene tape, the utilization of braided suture has been significantly associated with a reduction in the incidence of gestational age at delivery <37 weeks, as well as a decreased risk of PPROM and PROM. However, the use of braided sutures did not result in discernible differences in the rates of chorioamnionitis or adverse neonatal outcomes. Synopsis: Compared with cervical cerclage with Mersilene tape, the procedure with braided suture can reduce the incidence of preterm birth at <37 weeks, PPROM, and PROM more effectively.

This study aimed to synthesize the existing evidence on perinatal outcomes after autologous cryopreserved ovarian tissue transplantation, concurrently identifying key factors influencing these outcomes. A comprehensive search was performed on MEDLINE, Embase, and Cochrane Library databases to identify relevant studies on the effect of autologous cryopreserved ovarian tissue transplantation on perinatal outcomes from inception to October 22, 2023. Where there was missing information, the authors were contacted for updated data. Observational studies, such as cohort studies, case series, and case reports that reported a live birth after autologous cryopreserved ovarian tissue transplantation, were considered eligible. Studies lacking data on women's demographic characteristics, autologous cryopreserved ovarian tissue transplantation procedure details, or perinatal outcomes were excluded. In addition, cases involving fresh or nonautologous transplantations and those addressing primary ovarian insufficiency were excluded. Two reviewers (M.E. and E.U.) independently performed the study selection, data extraction, and risk of bias assessment, and the results were then reviewed together. The PRISMA guidelines were followed, and the protocol was registered on PROSPERO (CRD42023469296). This review included 58 studies composed of 122 women with 162 deliveries (154 singletons and 8 twins) after autologous cryopreserved ovarian tissue transplantation, resulting in 170 newborns. Of note, 83.6% of the women had a malignant disease. Moreover, most of these women (51.0%) were exposed to some form of chemotherapy before ovarian tissue cryopreservation. Of the 162 childbirths, 108 (66.7%) were conceived naturally, and 54 (33.3%) were conceived through assisted reproductive techniques. The birthweight of 88.5% of newborns was appropriate for gestational age, whereas 8.3% and 3.1% were small for gestational age and large for gestational age, respectively. The preterm birth rate was 9.4%, with the remaining being term deliveries. Hypertensive disorders of pregnancy were noted in 18.9% of women, including pregnancy-induced hypertension in 7.6%, preeclampsia in 9.4%, and hemolysis, elevated liver enzymes, and low platelet count in 1.9%. The incidences of gestational diabetes mellitus and preterm premature rupture of membranes were 3.8% for each condition. Neonatal anomalies were reported in 3 transplant recipients with 4 newborns: arthrogryposis, congenital cataract, and diaphragmatic hernia in a twin. Finally, among the recipients' characteristics, not receiving chemotherapy before ovarian tissue cryopreservation (odds ratio, 0.23; 95% confidence interval, 0.07–0.72; P =.012) and natural conception (odds ratio, 0.29; 95% confidence interval, 0.09–0.92; P =.035) were associated with a lower perinatal complication rate. On the basis of low certainty evidence from observational studies, perinatal complication rates did not increase after autologous cryopreserved ovarian tissue transplantation compared with the general pregnant population, except for preeclampsia. This could be due to chemotherapy exposure, underlying medical conditions, and the common use of assisted reproductive techniques. Further larger studies are needed to explore the causes of increased preeclampsia incidence in autologous cryopreserved ovarian tissue transplantation pregnancies. [ABSTRACT FROM AUTHOR]

Objective: This study aimed to explore whether subclinical hypothyroidism (SCH) treated with levothyroxine in pregnancy complicated by gestational diabetes mellitus (GDM) is associated with an increased risk of gestational hypertensive disorders (GHDs) (gestational hypertension and preeclampsia). Methods: 96 pregnant women with GDM were enrolled in this study and grouped as per the European Thyroid Association criteria into the SCH (n = 21) and euthyroid groups (n = 75). All subjects were tested for anthropometric parameters, maternal glucose homeostasis parameters, lipid levels, thyroid function tests, and blood pressure. All GDM pregnant women received nutritional and insulin therapy where needed, and the SCH group received levothyroxine treatment. Then, the maternal and newborn outcomes were compared. Data were analyzed using Student's t-test, Mann–Whitney U, and Chi-square tests wherever applicable. p values of <0.05 were considered significant. Results: Patients with GDM and SCH had a pre-pregnancy BMI and BMI at inclusion in the study smaller than those of the euthyroid group (p = 0.0004, p = 0.0009). There were no significant differences between groups regarding the incidence of GHD, preterm prelabor rupture of membranes (PPROMs), macrosomia, low birth weight, and fetal distress (p > 0.05). Patients with GDM and SCH treated with levothyroxine had more premature delivery than the euthyroid group (p = 0.03). Conclusions: Subclinical hypothyroidism treated with levothyroxine in women with GDM does not increase the risk of gestational hypertensive disorders, but is associated with increased risk for prematurity.

A 36-year-old primigravida conceived dichorionic diamniotic twins via in vitro fertilization. The first twin experienced premature rupture of membranes at 18 weeks and 5 days of gestation. Despite antibiotic treatment, the first fetus suffered intrauterine fetal death and was delivered three days later at 19 weeks and 1 day. Using ritodrine, the remaining umbilical cord was repositioned, and an emergency cerclage was performed. Ritodrine was continuously administered post-surgery but discontinued at 24 weeks and 3 days due to improved uterine contractions. The patient later delivered a healthy baby via cesarean section at 38 weeks due to decreased fetal movement and breech presentation. This rare case of premature rupture of membranes in one of the twins before the viability term, followed by a successful delayed delivery, is presented here. [ABSTRACT FROM AUTHOR]
