Oxytocin vs oral misoprostol for PROM induction in nulliparas with unfavorable cervix: a randomized trial

BackgroundInduction of labor (IOL) is recommended following prelabor rupture of membranes (PROM). The optimal method for IOL and need for cervical ripening in those with PROM and an unfavorable cervical examination is unclear. ObjectiveTo determine if oxytocin or oral misoprostol results in a shorter time to delivery among nulliparous patients with an unfavorable cervical examination and PROM diagnosis and to evaluate patient satisfaction with both methods. Study DesignThis is a randomized clinical trial conducted at an urban tertiary care center from 2019 to 2023. Subjects were nulliparas ≥36 weeks with an unfavorable starting cervical exam (≤2 cm and Bishop <8). The primary outcome was time from IOL to delivery in hours compared between oxytocin vs oral misoprostol. Secondary outcomes included suspected intraamniotic infection, cesarean delivery, composite maternal and neonatal morbidity, and patient satisfaction (assessed by Birth Satisfaction Scale-Revised). Sub-group analyses for those with BMI ≥ 30 kg/m2 and cervical dilation ≥1 cm were performed. We required 148 subjects to have 80% power to detect a 2-hour difference in time to delivery. The study was stopped early by the data safety monitoring board due to feasibility concerns in recruiting desired sample size. ResultsA total of 108 subjects were randomized: 56 oxytocin; 52 oral miso. The median gestational age at induction was 39.5 weeks; the mean starting cervical dilation was 1.1 cm. There was no statistical difference in time to delivery between groups overall: 14.9 hours oxytocin vs 18.1 hours oral misoprostol (P=.06). In sub-group analyses, there was a 5 hours shorter time to delivery with oxytocin for those with a BMI ≥ 30 kg/m2 (16.6 hours oxytocin vs 21.8 hours oral misoprostol, P .04) and 4.5 hours shorter time to delivery with oxytocin for those with cervix ≥1 cm (12.9 hours oxytocin vs 17.3 hours oral misoprostol, P .04). There were no differences in intraamniotic infection, cesarean delivery, maternal or neonatal morbidity between the groups. Patient satisfaction was higher for those receiving oxytocin compared to misoprostol (29.0 vs 26.3, P=.03). ConclusionAmong nulliparas with PROM and an unfavorable cervix, there was no difference in overall time to delivery between oxytocin and oral misoprostol. This result should be interpreted with caution given early study discontinuation and inadequate power. However, a shorter time to delivery with oxytocin was noted in obese patients and those with cervical dilation of at least 1 cm. Furthermore, patient satisfaction was higher in the oxytocin group, and there was no increased risk of neonatal or maternal morbidity with oxytocin.

Analysis of adverse late-term pregnancy outcomes after cervical cold knife conization

Objective: To investigate the effects of cervical cold knife conization (CKC) on preterm delivery, other pregnancy complications and neonatal outcomes, and explore the relationship between preterm delivery risk and the depth and volume of conization. Methods: The clinical data and pregnancy outcomes of 272 women who underwent CKC in Peking Union Medical College Hospital from January 2002 to March 2018 (conization group) and 1 647 pregnant women who gave birth in Peking Union Medical College Hospital during January to December 2019 (control group) were collected. The preterm delivery, premature rupture of membranes, other pregnancy complications and neonatal outcomes of the two groups were compared, and the relationship between the depth and volume of conization and the risk of preterm delivery in postoperative singleton pregnancy was analyzed. Results: (1) There were no significant differences between the two groups in delivery age, parity, proportion of singleton pregnancy, proportion of assisted reproductive technology (all P>0.05). (2) The rate of preterm delivery in the conization group was significantly higher than that in the control group [14.8% (39/264) vs 5.7% (91/1 589); χ2=28.397, P<0.001]. There were still significant differences in preterm delivery rates between the two groups at <34 weeks and 34-37 weeks (all P<0.01). There was no significant difference in the incidence of premature rupture of membrane between the two groups [23.5% (62/264) vs 23.4% (372/1 589); χ2=0.001, P=0.979], but the incidence of preterm premature rupture of membrane in the conization group was significantly higher than that in the control group [11.4% (30/264) vs 2.2% (35/1 589); χ2=56.132, P<0.001]. (3) The rate of cesarean section in the conization group was higher than that in the control group [59.6% (162/272) vs 38.8% (639/1 647); χ2=41.377, P<0.001]. The birth weight of preterm infants in the conization group was significantly higher than that in the control group [(2 409±680) vs (2 150±684) g; t=2.184, P=0.030]. However, there were no statistically significant differences in the incidence of gestational diabetes mellitus, hypertensive disorders in pregnancy, the birth weight of full-term infants, incidence of small for gestational age infant and neonatal intensive care unit admission rate between the two groups (all P>0.05). (4) The preterm delivery rates of coning depth >15 mm, cone size ≥2 cm3 and cone size <2 cm3 were higher than that in the control group (all P<0.05). When the coning depth ≤15 mm, the preterm delivery rate in the conization group was higher than that in the control group, but there was no significant difference (P=0.620). The rate of preterm delivery of pregnant women with coning depth >15 mm was significantly higher than those with coning depth ≤15 mm (RR=3.084, 95%CI: 1.474-6.453; P=0.001). There was no significant difference in the preterm delivery rate between pregnant women with cone size >2 cm3 and those with cone size ≥2 cm3 (RR=1.700, 95%CI: 0.935-3.092; P=0.077). Conclusion: The risk of preterm delivery and preterm premature rupture of membranes in subsequent pregnancies are increased after cervical CKC, and the risk of preterm delivery is positively correlated with the depth of cervical coning.

Value of fetal echocardiographic examination in pregnancies complicated by preterm premature rupture of membranes.

Cardiopulmonary and infectious complications are more common in preterm newborns after preterm premature rupture of membranes (pPROM). Fetal echocardiography may be helpful in predicting neonatal condition. Our aim was to assess the cardiovascular changes in fetuses from pregnancies complicated by pPROM and possible utility in predicting the intrauterine or neonatal infection, and neonatal heart failure (HF). It was a prospective study enrolling 46 women with singleton pregnancies complicated by pPROM between 18+0 and 33+6 weeks of gestation and followed until delivery. 46 women with uncomplicated pregnancies served as a control group. Fetal echocardiographic examinations with the assessment of cardiac structure and function (including pulmonary circulation) were performed in all patients. Mean gestational age of pPROM patients was 26 weeks. Parameters suggesting impaired cardiac function in fetuses from pPROM were: higher right ventricle Tei index (0.48 vs. 0.42 p<0.001), lower blood flow velocity in Ao z-score (0.14 vs. 0.84 p=0.005), lower cardiovascular profile score (CVPS), higher rate of tricuspid regurgitation (18.2 % vs. 4.4 % p=0.04) and pericardial effusion (32.6 vs. 0 %). Intrauterine infection was diagnosed in 18 patients (39 %). 4 (8.7 %) newborns met the criteria of early onset sepsis (EOS). HF was diagnosed in 9 newborns. In fetal echocardiographic examination HF group had shorter mitral valve inflow time and higher left ventricle Tei index (0.58 vs. 0.49 p=0.007). Worse cardiac function was observed in fetuses from pPROM compared to fetuses from uncomplicated pregnancies.

Possible adverse events of imidazole antifungal drugs during treatment of vulvovaginal candidiasis: analysis of the FDA Adverse Event Reporting System

Azole antifungal drugs are commonly used to treat vulvovaginal candidiasis (VVC). The nephrotoxicity and developmental toxicity of azole drugs have not been systematically analyzed in the real world. We used the FDA Adverse Event Reporting System (FAERS) to investigate the adverse events (AEs) associated with imidazole therapy for VVC. FAERS data (from quarter 1 2004 to quarter 3 2022) were retrieved using OpenVigil 2.1, and AEs were retrieved and standardized according to the Medical Dictionary for Regulatory Activities (MedDRA). In the top 10 System Organ Class (SOC), all four drugs have been found to have kidney and urinary system diseases and pregnancy. We found significant signals, including clotrimazole [bladder transitional cell carcinoma, (report odds ratio, ROR = 291.66)], [fetal death, (ROR = 10.28)], ketoconazole[nephrogenic anemia (ROR = 22.1)], [premature rupture of membranes (ROR = 22.91 46.45, 11, 3)], Miconazole[hematuria (ROR = 19.03)], [neonatal sepsis (ROR = 123.71)], [spontaneous abortion (ROR = 5.98)], Econazole [acute kidney injury (ROR = 4.41)], [spontaneous abortion (ROR = 19.62)]. We also discovered new adverse reactions that were not reported. Therefore, when using imidazole drugs for treatment, it is necessary to closely monitor the patient's renal function, pay attention to the developmental toxicity of the fetus during pregnancy, and be aware of potential adverse reactions that may occur.

The Chorioamnionitis - Still an Enigma in Perinatology

Abstract Chorioamnionitis is one of the most common causes of preterm premature rupture of fetal membranes and consequent preterm birth. The variety of mechanisms underlie pathophysiology of chorioamnionitis represents its greatest enigma. The unspecific clinical manifestations of chorioamnionitis considered an aggravating issue for perinatologist to diagnose it timely. There are no absolutely sensitive, non-invasive diagnostic procedures for certain establishment of chorioamnionitis diagnosis. The more sensitive diagnostic procedures are also invasive, so the question of their application in routine practice arises. Certainly, the perinatologist is always in a dilemma when there is a suspicion of chorioamnionitis, whether and how it should be treated, having in mind the facts about possible side effects on the fetus, but also on the mother. This paper presents a summary of all known facts about the etiopathogenesis, classification and clinical manifestations of chorioamnionitis, providing a basis for further research regarding the identification of more sensitive diagnostic markers, as well as the treatment of this condition.

The vaginal immunoproteome for the prediction of spontaneous preterm birth: A retrospective longitudinal study.

Preterm birth is the leading cause of neonatal morbidity and mortality worldwide. Most cases of preterm birth occur spontaneously and result from preterm labor with intact (spontaneous preterm labor [sPTL]) or ruptured (preterm prelabor rupture of membranes [PPROM]) membranes. The prediction of spontaneous preterm birth (sPTB) remains underpowered due to its syndromic nature and the dearth of independent analyses of the vaginal host immune response. Thus, we conducted the largest longitudinal investigation targeting vaginal immune mediators, referred to herein as the immunoproteome, in a population at high risk for sPTB. Vaginal swabs were collected across gestation from pregnant women who ultimately underwent term birth, sPTL, or PPROM. Cytokines, chemokines, growth factors, and antimicrobial peptides in the samples were quantified via specific and sensitive immunoassays. Predictive models were constructed from immune mediator concentrations. Throughout uncomplicated gestation, the vaginal immunoproteome harbors a cytokine network with a homeostatic profile. Yet, the vaginal immunoproteome is skewed toward a pro-inflammatory state in pregnant women who ultimately experience sPTL and PPROM. Such an inflammatory profile includes increased monocyte chemoattractants, cytokines indicative of macrophage and T-cell activation, and reduced antimicrobial proteins/peptides. The vaginal immunoproteome has improved predictive value over maternal characteristics alone for identifying women at risk for early (<34 weeks) sPTB. The vaginal immunoproteome undergoes homeostatic changes throughout gestation and deviations from this shift are associated with sPTB. Furthermore, the vaginal immunoproteome can be leveraged as a potential biomarker for early sPTB, a subset of sPTB associated with extremely adverse neonatal outcomes. This research was conducted by the Perinatology Research Branch, Division of Obstetrics and Maternal-Fetal Medicine, Division of Intramural Research, Eunice Kennedy Shriver National Institute of Child Health and Human Development, National Institutes of Health, U.S. Department of Health and Human Services (NICHD/NIH/DHHS) under contract HHSN275201300006C. ALT, KRT, and NGL were supported by the Wayne State University Perinatal Initiative in Maternal, Perinatal and Child Health.

Black-white differences in chronic stress exposures to predict preterm birth: interpretable, race/ethnicity-specific machine learning model

BackgroundDifferential exposure to chronic stressors by race/ethnicity may help explain Black-White inequalities in rates of preterm birth. However, researchers have not investigated the cumulative, interactive, and population-specific nature of chronic stressor exposures and their possible nonlinear associations with preterm birth. Models capable of computing such high-dimensional associations that could differ by race/ethnicity are needed. We developed machine learning models of chronic stressors to both predict preterm birth more accurately and identify chronic stressors and other risk factors driving preterm birth risk among non-Hispanic Black and non-Hispanic White pregnant women.MethodsMultivariate Adaptive Regression Splines (MARS) models were developed for preterm birth prediction for non-Hispanic Black, non-Hispanic White, and combined study samples derived from the CDC’s Pregnancy Risk Assessment Monitoring System data (2012–2017). For each sample population, MARS models were trained and tested using 5-fold cross-validation. For each population, the Area Under the ROC Curve (AUC) was used to evaluate model performance, and variable importance for preterm birth prediction was computed.ResultsAmong 81,892 non-Hispanic Black and 277,963 non-Hispanic White live births (weighted sample), the best-performing MARS models showed high accuracy (AUC: 0.754–0.765) and similar-or-better performance for race/ethnicity-specific models compared to the combined model. The number of prenatal care visits, premature rupture of membrane, and medical conditions were more important than other variables in predicting preterm birth across the populations. Chronic stressors (e.g., low maternal education and intimate partner violence) and their correlates predicted preterm birth only for non-Hispanic Black women.ConclusionsOur study findings reinforce that such mid or upstream determinants of health as chronic stressors should be targeted to reduce excess preterm birth risk among non-Hispanic Black women and ultimately narrow the persistent Black-White gap in preterm birth in the U.S.

Modern trends in the treatment of bacterial vaginosis in primigravida in the first half of gestation

Pregnancy with bacterial vaginosis (BV) is accompanied by a high risk of various obstetric and perinatal complications, including miscarriage, preterm birth, placental dysfunction, premature rupture of membranes, chorionamnionitis, polyhydramnios, etc. Screening for BV is carried out in the first half of pregnancy during the registration of a woman, however, taking into account the gestational age, many drugs with antimicrobial and antiseptic effects are categorically contraindicated, as they have an embryo- and fetotoxic effect.Timely detection and correction of microbiocenosis disorders of the birth canal is an extremely important element to prevent a number of obstetric and perinatal complications. A balanced approach in the treatment of vaginal dysbiosis consists in the use of modern combined antiseptic preparations for local treatment, which do not contain antibacterial components and are safe for use during pregnancy.The objective: to determine the effectiveness of the treatment of BV in primigravida women in the first half of pregnancy.Materials and methods. 126 primigravida women aged 18–35 years in the first half of pregnancy were examined during pregnancy registration. The participants were selected randomly.The main group included 36 primigravida women with a gestation period of up to 20 weeks with a diagnosis of BV according to the Amsel and Hay–Ison criteria, who were treated with a combined antiseptic drug (chlorhexidine and chlorophyllipt) – suppository vaginally twice a day, the course of treatment – 5 days. The control group included 30 primigravida women with a gestational age of up to 20 weeks with vaginal normocenosis.For all women the pH of vaginal secretions was determined, followed by microscopy of a native smear, stained according to Gram, and a cultural study was performed. Adherence to the Amsel criteria was also determined, followed by evaluation by the Hay–Ison criteria. The clinical effect was evaluated according to clinical examination data before and on the 6th day of treatment with a combined antiseptic drug (chlorhexidine and chlorophyllipt) using bacterioscopic and bacteriological methods.Results. A normal pH was observed only in every fifth part of examined pregnant woman (28 women – 22.2%), while in the rest patients the acidity of the vaginal environment was not normal. Normocenosis was observed only among 1/3 of primigravida women (37 women – 29.4%). A third of the patients were diagnosed with BV (36 women - 28.6%), every fifth pregnant woman – vulvovaginal candidiasis (28 women - 22.2%).In healthy pregnant women (control group, n=30), the main component of the microbiocenosis was Lactobacillus spp. with a small content of facultatively anaerobic microorganisms. In the main group Atopobium vaginae (38.9%), Gardnerella vaginalis (33.3%), Prevotella bivia (27.8%), Candida spp. (22.2%), as well as Lactobacillus spp. in low titers were dominated. Before the treatment all 36 pregnant women of the main group corresponded to the 3rd type according to the Hay–Ison criteria with the dominance of Gardnerella vaginalis and/or Mobiluncus morphotypes and a small number or complete absence of lactobacilli, which served as the basis for establishing the diagnosis of BV. After treatment type 1 (94.4%) was found in 34 pregnant women, and type 2 (5.6%) – in 2 pregnant women.The results of the microbiological study indicate the normalization of the content of the biotope with the predominance of Lactobacillus spp. in women of the main group, in whom the indicators were similar to the control group.Conclusions. Since pregnancy with BV is accompanied by a high risk of obstetric and perinatal complications, the premorbid background of which is laid already in the first half of pregnancy, there is an urgent need to carry out the birth canal sanitation. The drugs of choice for the BV in the first half of pregnancy are local combined agents of a wide spectrum of action.A universal antiseptic with an anti-inflammatory effect, which includes two components – chlorhexidine and chlorophyllipt, fully meets the recommendations for efficiency and safety and can be used for the BV in the first half of pregnancy.

Fetoscopic Tracheal Occlusion for Isolated Severe Left Diaphragmatic Hernia: A Systematic Review and Meta-Analysis.

Background: We aimed to conduct a systematic review and meta-analysis to evaluate the fetoscopic tracheal occlusion in patients with isolated severe and left-sided diaphragmatic hernia. Methods: Cochrane Library, Embase, and PubMed (Medline) databases were searched from inception to February 2024 with no filters or language restrictions. We included studies evaluating the outcomes of fetoscopic intervention compared to expectant management among patients with severe congenital diaphragmatic hernia exclusively on the left side. A random-effects pairwise meta-analysis was performed using RStudio version 4.3.1. Results: In this study, we included 540 patients from three randomized trials and five cohorts. We found an increased likelihood of neonatal survival associated with fetoscopic tracheal occlusion (Odds Ratio, 5.07; 95% Confidence Intervals, 1.91 to 13.44; p < 0.01) across general and subgroup analyses. Nevertheless, there were higher rates of preterm birth (OR, 5.62; 95% CI, 3.47-9.11; p < 0.01) and preterm premature rupture of membranes (OR, 7.13; 95% CI, 3.76-13.54; p < 0.01) in fetal endoscopic tracheal occlusion group compared to the expectant management. Conclusions: Our systematic review and meta-analysis demonstrated the benefit of fetoscopic tracheal occlusion in improving neonatal and six-month postnatal survival in fetuses with severe left-sided CDH. Further studies are still necessary to evaluate the efficacy of tracheal occlusion for isolated right-sided CDH, as well as the optimal timing to perform the intervention.

Association between Gestational Age and Perinatal Outcomes in Women with Late Preterm Premature Rupture of Membranes.

The American College of Obstetricians and Gynecologists (ACOG) suggests expectant management until 34 weeks for patients with preterm premature rupture of membranes (PPROM). New data suggest extending to 37 weeks might enhance neonatal outcomes, reducing prematurity-linked issues. This study aims to assess adverse neonatal outcomes across gestational ages in women with PPROM. A retrospective cohort study was performed using linked vital statistics and the International Classification of Diseases, Ninth Revision data. Gestational age at delivery ranged from 32 to 36 weeks. Outcomes include neonatal intensive care unit (NICU) admission >24 hours, neonatal sepsis, respiratory distress syndrome, necrotizing enterocolitis, intraventricular hemorrhage, and neonatal death. Multivariate regression analyses and chi-square tests were employed for statistical comparisons. In this cohort of 28,891 deliveries, there was a statistically significant decline in all studied adverse neonatal outcomes with increasing gestational age, without an increase in neonatal sepsis. At 32 weeks, 93% of newborns were in the NICU >24 hours compared with 81% at 34 weeks and 22% at 36 weeks (p < 0.001). At 32 weeks, 20% had neonatal sepsis compared with 11% at 34 weeks and 3% at 36 weeks (p < 0.001). At 32 weeks, 67% had respiratory distress syndrome compared with 44% at 34 weeks and 12% at 36 weeks (p < 0.001). In the setting of PPROM, later gestational age at delivery is associated with decreased rates of adverse neonatal outcomes without an increase in neonatal sepsis. · The ACOG recommends expectant management until 34 weeks for patients with PPROM.. · However, expectant management to 37 weeks might improve neonatal outcomes.. · Later gestational age at delivery was associated with decreased rates of adverse neonatal outcomes.. · Later gestational age at delivery was not associated with an increase in neonatal sepsis.. · The management of PPROM is complex and should be individualized..

(127) TRAUMA INFORMED CARE TO REDUCE ANTEPARTUM COMPLICATIONS IN SURVIVORS OF TRAUMA

Abstract Introduction Life trauma permeates through society and across cultures. It impacts the individual, community, and society. Trauma may include but is not limited to adverse childhood experiences (ACEs), sexual assault and violence, domestic violence, and interpersonal violence (IPV). In the United States, 1 in 3 women experience physical IPV, 1 in 4 experience sexual assault, and 17% of adults have experienced 4 or more ACEs (CDC 2022, 2023). Experiencing trauma leads to a cascade of effects that infiltrate every aspect of life and causes higher levels of chronic stress. In those who are pregnant or giving birth, a history of trauma, particularly sexual assault, leads to adverse antepartum outcomes. Objective After this presentation, the learner will be able to: 1. Define trauma (ACEs, sexual assault, DV, IPV). 2. State the signs and symptoms of trauma. 3. Identify the antepartum complications associated with a history of trauma. 4. Explain the impact that a history of sexual assault has on the birth giver. 5. Define trauma informed care. 6. Identify the components of trauma informed care. 7. State the importance of using trauma informed care as a midwife and WHNP. Methods The methods used to address this topic include a literature review and podium style presentation of findings. Results Main findings include increased rates of miscarriage, preterm birth, post traumatic stress disorder, placental abruption, premature rupture of membranes, and low birth weight in pregnant survivors of past trauma. Additionally, the dynamic interplay between the Social Determinants of Health and violence experienced during pregnancy must be considered. Low household income, racism, lack of social support, as well as food and housing insecurity increased rates of intimate partner violence experienced during pregnancy. Trauma informed care has been shown to reduce psychological symptom severity and has been integrated into midwifery care to attempt to reduce these outcomes and prevent further traumatization of the client. Conclusions As pregnancy and childbirth are intimate and personal in nature, using a trauma informed model of care is crucial to identifying clients with trauma histories and caring for them in a manner that is cognizant of their lived experiences and potential antepartum outcomes. Future providers must receive adequate education and training regarding trauma informed care in an effort to prevent adverse outcomes and prevent re-traumatization of their clients. Disclosure No.

Fetal inflammatory response syndrome predicts early-onset sepsis and cystic periventricular leukomalacia in preterm neonates: A retrospective study.

Fetal inflammatory response syndrome (FIRS), the fetal equivalent of chorioamnionitis, is associated with poorer neonatal outcomes. FIRS is diagnosed through placental histology, namely by the identification of funisitis (inflammation of the umbilical cord) and chorionic vasculitis (inflammation of fetal vessels within the chorionic plate). The aim of this study was to identify and evaluate associations between FIRS and neonatal outcomes in preterm neonates. We performed a retrospective cohort study at a level III neonatal intensive care unit (NICU), from January 1st 2008 to December 31st 2022, involving all inborn neonates with a gestational age below 30 weeks. We compared preterm neonates based on whether their placental histology described funisitis with chorionic vasculitis (FCV) or not. The study included 113 preterms, 27 (23.9%) of those had FCV and 86 (76.1%) did not. After adjusting to gestational age, prolonged rupture of membranes and preeclampsia, FCV was independently associated with the development of early-onset sepsis (OR = 7.3, p = 0.021) and cystic periventricular leukomalacia (OR = 4.6, p = 0.004). The authors identified an association between FIRS and the development of early-onset sepsis and cystic periventricular leukomalacia, highlighting the importance of early detection and management of this condition in order to improve long-term neonatal outcomes.

The Sensitivity and Specificity of Measuring the Thickness of Myometrium to Predict the Time of Spontaneous Labour in Preterm Prelabor Rupture of Membranes and Oligohydramnios

The Sensitivity and Specificity of Measuring the Thickness of Myometrium to Predict the Time of Spontaneous Labour in Preterm Prelabor Rupture of Membranes and Oligohydramnios

Uncertain prelabor rupture of membranes at term and associated delivery outcomes.

To determine whether equivocal prelabor rupture of membranes (PROM) cases are associated with adverse outcomes. A retrospective study was conducted in a tertiary medical center between July 2012 and March 2022. The cohort comprised all women diagnosed with term PROM (≥37 gestational weeks), divided into two groups. (1) Certain PROM-suggestive history of a watery vaginal discharge confirmed by visualization of fluid leaking from the cervix or pooling in the vagina on speculum examination. (2) Uncertain PROM-suggestive history of a watery vaginal discharge not supported by speculum examination. All patients were hospitalized and gave birth spontaneously or following either expectant management for up to 24 h from PROM or induction. The primary outcome measure was cesarean delivery (CD) rate. Secondary outcome measures were adverse maternal/neonatal events. Of the 2012 women included in the study, 1750 had certain PROM and 262 uncertain PROM. CD rate was 5.8% in the certain PROM group and 8.8% in the uncertain PROM group; the difference was not statistically significant (P = 0.074). There was a significant between-group difference in the rate of CD due to failed induction on univariate analysis (0.69% vs 2.67%, respectively, P = 0.007), but it was not maintained on multivariate logistic regression (odds ratio 0.37, 95% confidence interval: 0.12-1.17). Other maternal and neonatal outcomes were similar in the two groups. Our findings indicate that following the same management guidelines for equivocal cases of ruptured membranes as for confirmed cases of term PROM did not compromise maternal or fetal outcomes.

Prevalence of Physical Disorders during Pregnancy in Turkey: A Systematic Review and Meta-Analysis

Objectives: To determine the prevalence of physical disorders, and to examine hospitalization rates and the causes of hospitalization during the period of pregnancy, basing our conclusions on observational studies carried out in Turkey. Methods: This is a systematic review and meta-analyses of cross-sectional studies. The literature search for the study was performed in April 2021 on the PubMed, EBSCO, OVID, Web of Science, PsycINFO, Clinics of Turkey-Turkey Reference Series, TR Series and Higher Council of Education-National Thesis Centre electronic data bases. Results: Nineteen articles were included in this meta-analysis, amounting to a total volume of 159,022 samples. The studies contained data on 14 different physical health problems that developed during pregnancy. Based on the data, we observed that authors of the meta-analyses estimated a prevalence of 16% for urinary infection, 10% for preterm labour, 7.8% for gestational diabetes, 8.7% for premature rupture of membranes, 4% for hyperemesis gravidarum, 2.8% for preeclampsia, 2.7% for gestational hypertension, 0.3% for HELLP syndrome, 0.1% for eclampsia, 6.6% for threat of miscarriage, 3.8% for miscarriage, 1.2% for a history of bleeding in the third trimester, 0.4% for placental abruption, and 0.3% for placenta previa. None of the studies contained any report on hospitalization rates and the causes of hospitalization during pregnancy. Conclusion: We obtained results in this systematic review that pointed to evidence that some preventable physical disorders and some that would necessitate hospitalization during pregnancy were prevalent, but no data on hospitalization rates and the causes of hospitalization could be reached.

The impact of premature rupture of membrane on neonatal outcomes in infants born at 34 weeks gestation or later.

Premature rupture of membranes (PROMs) is a known risk for adverse neonatal outcomes, often leading to neonatal hospitalization due to suspected perinatal infection or other issues. This study assesses PROM's clinical impact on neonatal outcomes in infants born at 34 weeks of gestation or later. We studied hospitalized neonates born between December 2018 and November 2019, with gestational ages of 34 weeks or more and PROM diagnosis. We extracted patient data from clinical records, including demographics, maternal history, medical profiles, and neonatal outcomes. Neonates were categorized based on symptoms, PROM duration, neonatal intensive care unit (NICU) stay, and respiratory support. Data underwent thematic analysis. Of 275 neonates, the average PROM duration was 7.9 ± 8.1 hours, with 247 cases (89.8%) showing symptoms. Among them, 34 (12.4%) had PROM lasting over 18 hours, 48 (17.5%) were born prematurely, and 79 (28.7%) required intensive care. Symptomatic neonates had significantly higher rates of needing intensive care, respiratory support, prolonged antibiotics, and extended hospitalization ( p < 0.05). NICU stays (≥3 days) were significantly associated with prematurity (odds ratio [OR] = 5.49; 95% CI, 2.39-12.60) and an initial pH level <7.25 (OR = 3.35; 95% CI, 1.46-7.68). Extended respiratory support (≥3 days) was significantly correlated with tocolysis ≥7 days (OR = 13.20; 95% CI, 3.94-44.20), Apgar score <7 at 1 minute after birth (OR = 4.28; 95% CI, 1.67-10.97), and inadequate intrapartum antibiotic prophylaxis (IAP) (OR = 2.34; 95% CI, 1.04-5.23). Neonates born at or after 34 weeks of gestation with PROM should undergo vigilant monitoring if early symptoms (<24 hours) manifest. Risk factors for requiring NICU care or extended respiratory support (≥3 days) include prematurity, low initial pH (<7.25), prolonged tocolysis requirement (≥7 days), an Apgar score below 7 at 1 minute, and inadequate IAP.

Nomogram-based risk assessment for emergency cervical cerclage failure in patients with cervical insufficiency

BackgroundCervical insufficiency can lead to preterm birth and neonatal mortality. Emergency cervical cerclage is a surgical intervention aimed at preventing preterm birth in patients with cervical insufficiency. However, some patients may experience cerclage failure. This study aimed to identify the risk factors associated with cerclage failure and develop a predictive nomogram model for patients with cervical insufficiency undergoing emergency cervical cerclage. MethodsData of 200 patients who underwent emergency cervical cerclage for cervical insufficiency were retrospectively analyzed. Patients were categorized into successful and failed groups based on their ability to take the infant home. Univariate and multivariate logistic regression analyses were performed to identify risk factors for cerclage failure. A nomogram model was developed based on multivariate logistic regression results, and its performance was assessed using receiver operating characteristic curves, calibration plots, and decision curve analysis (DCA). ResultsUnivariate logistic regression analysis identified 11 potential risk factors for cerclage failure, including the presence of polycystic ovary syndrome (PCOS), vaginitis, cervical dilation, preoperative C-reactive protein, routine vaginal lavage after cervical cerclage, delivery, gestational age, extended days, chorioamnionitis, intrauterine infection, cervical laceration, and premature rupture of membranes. Multivariate logistic regression analysis revealed that PCOS, cervical dilation after cervical cerclage were independent risk factors for cerclage failure while routine vaginal lavage was a protective factor against failure. The nomogram predictive model demonstrated an area under the curve value of 0.975, indicating excellent discriminatory ability. The calibration plot showed good consistency between the nomogram predictions and actual observations. DCA demonstrated the strong clinical applicability of the nomogram. ConclusionsThis study successfully identified risk factors associated with emergency cervical cerclage failure in patients with cervical insufficiency and developed a predictive nomogram model. This model can assist clinicians in making informed decisions and accurately predicting the risk of cerclage failure in these patients.

Factors Related to the Incident of Premature Rupture of Membrane among Maternity Women

Embryo transfer impact: a comprehensive national cohort analysis comparing maternal and neonatal outcomes across varied embryo stages in fresh and frozen transfers.

The utilization of frozen embryo transfer not only enhances reproductive outcomes by elevating the likelihood of live birth and clinical pregnancy but also improves safety by mitigating the risks associated with ovarian hyperstimulation syndrome (OHSS) and multiple pregnancies. There has been an increasing debate in recent years regarding the advisability of making elective frozen embryo transfer the standard practice. Our study aims to determine the optimal choice between fresh and frozen embryo transfer, as well as whether the transfer should occur at the cleavage or blastocyst stage. In this retrospective cohort study conducted in Taiwan, data from the national assisted reproductive technology (ART) database spanning from January 1st, 2013, to December 31st, 2017, were analyzed. The study included 51,762 eligible female participants who underwent ART and embryo transfer. Pregnancy outcomes, maternal complications, and singleton neonatal outcomes were evaluated using the National Health Insurance Database from January 1st, 2013, to December 31st, 2018. Cases were categorized into groups based on whether they underwent fresh or frozen embryo transfers, with further subdivision into cleavage stage and blastocyst stage transfers. Exposure variables encompassed clinical pregnancy rate, live birth rate, OHSS, pregnancy-induced hypertension, gestational diabetes mellitus (DM), placenta previa, placental abruption, preterm premature rupture of membranes (PPROM), gestational age, newborn body weight, and route of delivery. Frozen blastocyst transfers showed higher rates of clinical pregnancy (CPR) and live births (LBR) compared to fresh blastocyst transfers. Conversely, frozen cleavage stage transfers demonstrated lower rates of clinical pregnancy and live birth compared to fresh cleavage stage transfers. Frozen embryo transfers were associated with reduced risks of OHSS but were linked to a higher risk of pregnancy-induced hypertension compared to fresh embryo transfers. Additionally, frozen embryo transfers were associated with a higher incidence of large for gestational age infants and a lower incidence of small for gestational age infants. The freeze-all strategy may not be suitable for universal application. When embryos can develop to the blastocyst stage, FET is a favorable choice, but embryos can only develop to the cleavage stage, fresh embryo transfer becomes a more reasonable option.

Candidiasis vulvovaginal en mujeres embarazadas

Introduction: Vulvovaginal candidiasis (VVC) is a candidiasis of the vulva, which is caused by species of Candida spp., and affects women worldwide. Pregnant women are more susceptible to CVV due to certain risk factors. In addition, it predisposes to premature birth. Objectives: To analyze the risk factors for vaginal candidiasis in pregnancy and highlight the importance of treating vaginal candidiasis during pregnancy as a risk prevention strategy for premature rupture of the membrane and preterm labor. Material and methods: A bibliographic, descriptive and retrospective review was carried out of documents published by scientific societies that describe the current diagnostic approach and complications of candidal vulvovaginitis in pregnancy, as well as research works and scientific articles that describe prevention and treatment of vulvovaginitis. For the bibliographic search, works published in the last 5 years will be included and several documentary sources will be reviewed considering key words such as: Candida albicans, pregnancy, vulvovaginal candidiasis and vaginitis, to identify relevant and pertinent scientific articles in English and Spanish pages. , in different databases such as: PubMed, Elsevier, NCBI, Google Scholar, medical bibliography and clinical practice guidelines will also be attached. Results: Vulvovaginal candidiasis (VVC) is a common infection caused by yeasts of the genus Candida that affects pregnant women more frequently than at any other time in their lives. The prevalence of infection varies between countries, with rates ranging between 10% and 50% in Latin America. CVV during pregnancy can lead to complications such as premature birth, low birth weight, neonatal infection, and an increased risk of urinary tract infections. Treatment options for VVC during pregnancy include clotrimazole and miconazole vaginal creams or suppositories, while fluconazole is not recommended during the first trimester due to the risk of congenital malformations. Conclusion: treatment of vaginal candidiasis during pregnancy is important to prevent complications and ensure the health of the mother and fetus
