BACKGROUND: Post-term pregnancy is an important factor in perinatal mortality and morbidity. Generally, to reduce perinatal mortality in pregnancy, the delivery is done before adverse perinatal morbidity occurs. To prevent prolonged pregnancy, labor is induced with chemical drugs and complementary therapies. Due to the side effects and contraindications of chemical medicine, the use of herbs has been investigated in the induction of labor in post-term pregnancy. OBJECTIVES: This study was done to identify the effect of chamomile on inducing labor in women with post-term pregnancy of Shahid Akbarabadi hospital in Tehran in 2013...

To investigate the efficacy of cervical pessary placement in preventing preterm birth and perinatal morbidity and mortality in asymptomatic women with a singleton pregnancy and a short cervix, we searched literature in relevant databases. The meta-analysis of the 3 included trials (1412 women) showed cervical pessary placement did not reduce the risk of spontaneous preterm birth <34 weeks in these women (risk ratio (RR), 0.71; 95% confidence interval (CI), 0.21-2.43, P = 0.59; I(2) = 90%). The sensitivity analyses by excluding one trial at one time showed the same results...

Zika virus (ZIKV) infection during pregnancy has been linked to severe birth defects, and the epidemiologic situation of the ZIKV epidemic in Ecuador is poorly understood. Guayaquil, Ecuador, has a tropical climate and experiences frequent outbreaks of dengue and chikungunya virus, and in December 2015, ZIKV was identified. Given the well-documented effects of ZIKV in pregnancy, including microcephaly, we tested for the presence of ZIKV in both plasma and cervical cytology of pregnant women. We report the identification of a population of pregnant women with a high incidence of ZIKV infection detected in the plasma and lower reproductive tract...

INTRODUCTION: There is documented concern that cerclage may cause cervical stenosis or changes to the cervical mucus, which may reduce fertility. The aim of this study is to determine whether placement of a preconception abdominal cerclage affects fertility. MATERIAL AND METHODS: This was a planned subgroup analysis of a randomized controlled trial comparing abdominal cerclage, high vaginal or low vaginal cerclage. Women with a history of previous second trimester miscarriage or preterm birth despite having a low vaginal cerclage, presenting to specialist preterm birth services in the UK, were eligible for inclusion...

AIM: A cohort study was performed to clarify the influence of risk factors on perinatal events (obstetric complications and/or perinatal deaths). METHODS: This cohort study reviewed 395 785 births from 2011 to 2013. Women with singleton pregnancies delivered after 22 weeks of gestation were included. The OR were determined on multivariate analysis. The perinatal event score (PES) for risk factors, which is the product of the OR of risk factors for obstetric complications, OR of risk factors for perinatal death, and OR of obstetric complications for perinatal death, was introduced to clarify the impact of each risk combination...

The objective of the present study was to determine the ovarian response induced with the prostaglandin-based protocol Synchrovine (two doses of PGF2α given 7 d apart), as well as the fertility after FTAI. In Experiment 1, 15 females received the Synchrovine protocol using two different PGF2α analogues (Delprostenate vs. D-Cloprostenol). No differences in estrus response, time of ovulation and follicular dynamics were found between both groups (P < 0.05). The ovulation after Synchrovine was synchronized in a similar mean interval (68...

The ultrasonographic measurement of cervical length with a cutoff of 15mm is currently the best method to identify a group of asymptomatic women in the general population at risk of spontaneous preterm birth, especially among asymptomatic patients with a singleton pregnancy with no history of preterm birth. Cerclage and 17 alpha-hydroxyprogesterone caproate (17OHP-C) are ineffective to reduce the risk of preterm birth among asymptomatic patients with a short cervix in midtrimester. However, vaginal progesterone (200-mg capsules of micronized progesterone or gel containing 90mg progesterone) has been demonstrated effective in 2 large randomized trials to reduce the risk of preterm birth and possibly the composite morbidity and perinatal mortality associated among asymptomatic women with a short cervix in the general population screened by ultrasound of the cervix in midtrimester...

BACKGROUND: Twin pregnancies are at higher risks of velamentous cord insertion (VCI) and vasa previa. In-vitro fertilization (IVF) is an additional risk factor of abnormal cord insertion and thus the incidence of vasa previa is likely to increase over the next decades. OBJECTIVE: To evaluate the role of ultrasound imaging in optimizing the management of twins diagnosed with vasa previa antenatally. STUDY DESIGN: We searched our database for twin pregnancies diagnosed with vasa previa and managed antenatally using measurements of cervical length (CL) and performed a systematic review of articles which correlated prenatal diagnosis of vasa previa in twins and pregnancy outcome...

We aimed to determine the maternal characteristics (demographics, an obstetric history, and prior cervical excisional procedure) associated with a short mid-trimester cervical length (CL, defined as a CL of ≤ 25 mm) and whether having a short cervix explains the association between these maternal characteristics and spontaneous preterm delivery (SPTD, defined as a delivery before 34 weeks). This is a single-center retrospective cohort study of 3,296 consecutive women with a singleton pregnancy who underwent routine CL measurement between 20 and 24 weeks...

A cross-sectional study was conducted to evaluate the efficacy of rescue cerclage in patients with a dilated cervix and prolapsed foetal membranes. Thirty-five patients presenting with cervical dilatation and prolapsed foetal membranes were included in the study. A McDonald cerclage was placed in 27 patients. The duration of pregnancy prolongation and the number of deliveries after 28 weeks were evaluated. The median prolongation of pregnancy after cerclage placement differed significantly between the cerclage and bed-rest groups (64 days versus 13...

In this retrospective study based on cervical length (CL) measurements between 20 and 24 + 6 weeks, we examined the ability of CL to predict spontaneous preterm birth (SPTB) in 222 twin pregnancies using the receiver-operating curve (ROC) analysis and an a priori cut-off. CL predicted SPTB before 34 weeks. Using the ROC the selected cut-off was 37.5 mm. Positive predictive value (PPV) and negative predictive value (NPV) regarding SPTB before 34 weeks for 37.5 mm were 15.7% and 5.3% respectively. Using the 5th percentile, PPV and NPV regarding SPTB before 34 weeks for 24 mm were 41...

We previously reported that lactoferrin (LF) could be effective for preventing preterm delivery and intrauterine infections, based on data derived from mice and rabbits. Here we describe 6 women with a history of multiple pregnancy losses or preterm delivery and refractory bacterial vaginosis, who received prebiotic LF therapy and delivered an infant normally. Five of the women were pregnant and one was not at the time of this study. The Ethics Committee at Showa University Hospital and Showa University Koto Toyosu Hospital approved the therapeutic protocol...
