Objective In the era of group B Streptococcus (GBS) screening and intrapartum antibiotic prophylaxis (IAP), GBS colonization has been associated with a lower risk of chorioamnionitis, possibly due to a protective effect of IAP. We sought to confirm this finding and assess whether this association varies by gestational week at delivery. Study Design We performed a retrospective cohort study of term (37.0–42.6 weeks), singleton parturients with known GBS status who delivered from 2005 to 2021 at two academic medical centers in Israel. We excluded patients who underwent planned cesarean, out of hospital birth, or had a fetal demise. Patients received GBS screening and IAP for GBS positivity as routine clinical care. The primary outcome was a diagnosis of clinical chorioamnionitis as determined by the International Classification of Diseases 10th Revision code, compared between GBS-positive and -negative groups, and assessed by gestational week at delivery. Results Of 292,126 deliveries, 155,255 met inclusion criteria. In total, 30.1% were GBS positive and 69.9% were negative. GBS-positive patients were 21% less likely to be diagnosed with clinical chorioamnionitis than GBS-negative patients, even after controlling for confounders (1.5 vs. 2.2%, adjusted odds ratio: 0.79, 95% confidence interval: 0.68–0.92). When assessed by gestational week at delivery, there was a significantly greater difference in rates of clinical chorioamnionitis between GBS-positive versus GBS-negative groups with advancing gestational age: 1.5-fold difference at 38 to 40 weeks, but a twofold difference at 42 weeks. The risk of clinical chorioamnionitis remained stable in the GBS-positive group, but increased significantly in the GBS-negative group at 41- and 42-week gestation (2.0 vs. 2.9%, p < 0.01 at 41 weeks; up to 3.9% at 42 weeks, p < 0.01). Conclusion In a large multicenter cohort with universal GBS screening and IAP, GBS positivity was associated with a lower risk of chorioamnionitis, driven by an increasing rate of chorioamnionitis among GBS-negative patients after 40 weeks. Key Points GBS positivity and IAP may be associated with lower risk of chorioamnionitis. GBS-positive patients were less likely to be diagnosed with chorioamnionitis. This difference increased with advancing gestational age after 40 weeks. [ABSTRACT FROM AUTHOR]

Purpose: This study aimed to assess maternal and neonatal outcomes in patients with polyhydramnios attempting trial of labor after cesarean (TOLAC) compared to those undergoing planned repeat cesarean delivery (PRCD). Methods: A multi-center retrospective cohort study was conducted and included women with term singleton viable pregnancies following a single low-segment transverse cesarean delivery (CD) with a polyhydramnios diagnosis (maximal vertical pocket > 8 cm and/or Amniotic Fluid Index > 24 cm) within 14 days before birth who delivered between the years 2017 and 2021. Maternal and neonatal outcomes were compared between those attempting TOLAC and those opting for PRCD. The primary outcome was composite adverse maternal. Univariate analysis was followed by multivariate analysis to control for potential confounders. Results: Out of 358 included births with a previous CD, 208 (58.1%) attempted TOLAC, while 150 had PRCD (41.9%). The successful vaginal birth after cesarean (VBAC) rate was 82.2%, and no cases of uterine rupture, hysterectomy, or maternal intensive care unit admission occurred in either group. After controlling for potential confounders, no independent association between TOLAC and composite adverse maternal (adjusted odds ratio [aOR] 0.62, 95% confidence interval [CI] 0.32–1.20, p = 0.16) and neonatal (aOR 0.89, 95% CI 0.51–1.53, p = 0.67) adverse outcomes was demonstrated. Conclusion: In patients with a term diagnosed polyhydramnios, TOLAC appears to be a reasonable alternative associated with favorable outcomes. Larger prospective studies are needed to refine management strategies and enhance maternal and neonatal outcomes in this context. [ABSTRACT FROM AUTHOR]

This study aims to investigate whether trial of labor after cesarean delivery (TOLAC) in women with antepartum fetal death, is associated with an elevated risk of maternal morbidity. A retrospective multicenter. TOLAC of singleton pregnancies following a single low-segment incision were included. Maternal adverse outcomes were compared between women with antepartum fetal death and women with a viable fetus. Controls were matched with cases in a 1:4 ratio based on their previous vaginal births and induction of labor rates. Univariate analysis was followed by multiple logistic regression modeling. During the study period, 181 women experienced antepartum fetal death and were matched with 724 women with viable fetuses. Univariate analysis revealed that women with antepartum fetal death had significantly lower rates of TOLAC failure (4.4% vs. 25.1%, p < 0.01), but similar rates of composite adverse maternal outcomes (6.1% vs. 8.0%, p = 0.38) and uterine rupture (0.6% vs. 0.3%, p = 0.56). Multivariable analyses controlling for confounders showed that an antepartum fetal death vs. live birth isn't associated with the composite adverse maternal outcomes (aOR 0.96, 95% CI 0.21–4.44, p = 0.95). TOLAC in women with antepartum fetal death is not associated with an increased risk of adverse maternal outcomes while showing high rates of successful vaginal birth after cesarean (VBAC).

Background: With the increasing popularity of elective induction after 39 + 0 weeks, the question of whether induction of labor (IOL) is safe in women with isolated polyhydramnios has become more relevant. We aimed to evaluate the pregnancy outcomes associated with IOL among women with and without isolated polyhydramnios. Methods: This was a multicenter retrospective cohort that included women who underwent induction of labor at term. The study compared women who underwent IOL due to isolated polyhydramnios to low-risk women who underwent elective IOL due to gestational age only. The main outcome measure was a composite adverse maternal outcome, while the secondary outcomes included maternal and neonatal adverse pregnancy outcomes. Results: During the study period, 1004 women underwent IOL at term and met inclusion and exclusion criteria; 162 had isolated polyhydramnios, and 842 had a normal amount of amniotic fluid. Women who had isolated polyhydramnios had higher rates of the composite adverse maternal outcome (28.7% vs. 20.4%, p = 0.02), prolonged hospital stay, perineal tear grade 3/4, postpartum hemorrhage, and neonatal hypoglycemia. Multivariate analyses revealed that among women with IOL, polyhydramnios was significantly associated with adverse composite maternal outcome [aOR 1.98 (1.27–3.10), p < 0.01]. Conclusions: IOL in women with isolated polyhydramnios at term was associated with worse perinatal outcomes compared to low-risk women who underwent elective IOL. Our findings suggest that the management of women with polyhydramnios cannot be extrapolated from studies of low-risk populations and that clinical decision-making should take into account the individual patient's risk factors and preferences.

The aim of this multicenter retrospective cohort study was to examine the impact of maternal age on perinatal outcomes in multiparas, stratified according to maternal age in one- and two-year increments. The analysis involved 302,484 multiparas who delivered between the years 2003 and 2021 in four university-affiliated obstetrics departments. Maternal age was considered both as a continuous variable and in two-year intervals, as compared with a comparison group of parturients aged 25–30 years. The study focused on cesarean delivery and neonatal intensive care unit (NICU) admission as primary outcomes. The findings revealed that cesarean delivery rates increased as maternal age advanced, with rates ranging from 6.7% among 25–30 year olds, rising continuously from 13.5% to 19.9% between the age strata of 31 and 42, to exceeding 20% among those aged ≥ 43 years (p < 0.01 for each stratum when compared to 25–30 year old group). Similarly, NICU admission rates rose from 2.7% in the comparison group to 6% in parturients aged 45–46 years (p < 0.01 for each stratum when compared to 25–30 year old group). The study highlights the association between incrementally advanced maternal age and increased rates of maternal and neonatal complications, necessitating global awareness of these implications for family planning decisions and maternal care.

Introduction and hypothesis: Pregnancy and mode of delivery have a major effect on pelvic floor disorders (PFD). Assessing knowledge regarding PFD is essential not only for making more informed decisions regarding mode of delivery, but also for seeking help when PFD appear. The Prolapse and Incontinence Knowledge Questionnaire (PIKQ) is a validated tool that assesses women's knowledge regarding urinary incontinence (UI) and pelvic organ prolapse (POP). Validation of the Arabic version of the PIKQ had never been carried out. The purpose of this study was to conduct a condition specific validation among parturients of the PIKQ in the Arabic language. Methods: Translation of the PIKQ to the Arabic language was carried out according to international recommended guidelines. A cross-sectional study of pregnant women was conducted from June to September 2020 at the Soroka University Medical Center, Israel. The recommended 10:1 ratio between the number of subjects and the number of items in the questionnaire (n=24) was maintained. A total of 244 third trimester pregnant women have completed the Arabic version of the PIKQ. In addition to the validation of the psychometric characteristics, construct validity, criterion validity, and reliability were tested as well. Results: Initially, exploratory factor analysis (EFA) was conducted, resulting in two 12-item scales representing UI and POP. Then, to validate the scale construct we conducted confirmatory factor analysis (CFA). Results of the CFA demonstrated that the PIKQ displayed construct validity, with standardized factor loadings ranging from 0.30 to 0.62. Finally, Cronbach's alpha indicated a good internal reliability for the two factors UI and POP. Criterion validity further supported the validity of the scale. Conclusions: The Arabic version of the PIKQ is a new, reliable, consistent, and valid instrument to examine the level of knowledge regarding UI and POP in Arabic speaking pregnant women. This instrument may be used to assess women's knowledge about PFD and to direct the need for educational interventions that may empower women to make informed decisions regarding perinatal care.

Objective: To evaluate the maternal and neonatal outcomes of women with short interpregnancy intervals (IPI < 6 months) following a multifetal pregnancy. Study design: A multicenter retrospective cohort study of women with an index multifetal delivery and a subsequent singleton gestation between 2005 and 2021. The obstetrical outcomes of pregnancies following short IPI (<6 months) were compared to those with an IPI of 18–48 months. Additional analyses were also conducted for the other IPI groups: 7–17 months, and longer than 49 months, while women with an IPI of 18–48 months served as the reference group. The primary outcome was preterm birth (<37 weeks) rate. Secondary outcomes were other adverse maternal and neonatal outcomes. Univariate and multiple logistic regression analyses were performed. Results: Overall, 2514 women had a primary multifetal delivery with a subsequent singleton gestation at our medical centers; 160 (6.4%) had a short IPI, and 1142 (45.4%) had an optimal IPI. Women with a singleton gestation following a short IPI were younger, with lower rates of previous cesarean and fertility treatments. Women in the short IPI group had significantly higher rates of preterm birth <37 weeks, anemia (Hb < 11 gr%) on admission to the delivery room, and placental abruption. Multivariable logistic regression analysis demonstrated that short IPI is associated with an increased risk for preterm birth (aOR 2.39, 95% CI 1.12–5.11, p = 0.03). Conclusion: Short IPI following a multifetal gestation is associated with an increased risk for preterm birth in subsequent singleton pregnancy. [ABSTRACT FROM AUTHOR]

Introduction and hypothesis: The objective was to examine knowledge regarding pelvic floor disorders (PFDs) among women during the third trimester of pregnancy. Methods: A cross-sectional study was conducted at a large teaching medical center in Israel between June and September 2020. Women in their third trimester (N = 649) were asked to complete the validated Hebrew and Arabic versions of the Prolapse and Incontinence Knowledge Questionnaire (PIKQ). The PIKQ instrument examines the knowledge of two major PFDs: urinary incontinence (UI) and pelvic organ prolapse (POP). The study population included women over 18 years of age, in the third trimester, who speak and read Hebrew or Arabic fluently. Two separate scores were calculated, one for each section of the PIKQ. The association of questionnaire scores with the different independent variables was examined using Student's t test or one-way ANOVA. Correlations were examined using Pearson's or Spearman's correlation coefficient. Results: The Hebrew version was filled out by 405 women, and 244 women completed the Arabic version. The average questionnaire scores were 7.65 ± 2.8 and 5.32 ± 2 for the UI and POP sections respectively. Significantly higher average scores in both the UI and the POP sections were noted among health care workers (UI: 10.19 ± 2.3 vs 7.34 ± 2.6, p < 0.001; POP: 8.27 ± 2.7 vs 4.97 ± 2.6, p < 0.001), women with higher education (p < 0.001 in both parts) and those with higher incomes (p < 0.001 for both parts). Conclusions: Knowledge of PFD among women in the third trimester of pregnancy in Israel was found to be low. Founding educational programs for targeted groups may improve both the knowledge of PFD and the quality of life for these women. [ABSTRACT FROM AUTHOR]

Introduction and hypothesis: Pregnancy and delivery have a major effect on pelvic floor disorders. Assessing knowledge regarding pelvic floor disorders in childbearing age women and appropriate interventions will enable women to seek appropriate medical advice once pelvic floor disorders have developed. The purpose of this study was to validate the prolapse and incontinence knowledge questionnaire in the Hebrew language. Methods: Translation of the prolapse and incontinence knowledge questionnaire to the Hebrew language according to international recommended guidelines. A study was conducted to validate the questionnaire. The study took place between June to September 2020 in a tertiary medical center in Israel. A total of 240 third trimester pregnant women completed the Hebrew version of the prolapse and incontinence knowledge questionnaire. Construct validity, criterion validity and reliability tests were performed. Results: Factor analysis of the Hebrew version of the prolapse and incontinence knowledge questionnaire demonstrated 12 strong positive factor loadings to one principal factor in the prolapse and incontinence knowledge questionnaire-pelvic organ prolapse domain (FL > 0.3) and 10/12 in the prolapse and incontinence knowledge questionnaire-urinary incontinence domain. The Hebrew prolapse and incontinence knowledge questionnaire was found to have internal consistency, with Cronbach alpha coefficient of 0.745 for the urinary incontinence domain and 0.796 for the pelvic organ prolapse domain. Conclusions: The Hebrew version of the prolapse and incontinence knowledge questionnaire is a new, reliable, consistent, and valid instrument to examine the level of knowledge regarding pelvic floor disorders in Hebrew-speaking pregnant women.

In this article, we test one explanation of the causes of adoption of destabilization as a foreign policy. Destabilization, a risky policy which targets the political leadership of another sovereign state, is a widely-used foreign policy practice. But under-conceptualization, specifically around the causes of destabilization, has thus far limited its use in scholarly analysis of foreign policy. This paper aims to remedy that deficiency. Building on Taliaferro's (2004) balance-of-risk theory, we examine the rapid decay and adoption of destabilization in relations between the US and Cuba as a critical empirical test of this theory. We argue that the risky decision to adopt destabilization is the result of perceived crisis of security, economic and ideological interests. Our findings have implications for other scenarios and times, because they provide a better understanding of destabilization as a practice of governments against one another. [ABSTRACT FROM AUTHOR]
