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...

BACKGROUND: To reduce the morbidity and mortality associated with preterm birth, home uterine activity monitoring aims for early detection of increased contraction frequency, and early intervention with tocolytic drugs to inhibit labour and prolong pregnancy. However, the effectiveness of such monitoring is disputed. OBJECTIVES: To determine whether home uterine activity monitoring is effective in improving the outcomes for women and their infants considered to be at high risk of preterm birth, when compared with care that does not include home uterine activity monitoring...

In the clinic, the cardiotocogram (CTG), the combined registration of fetal heart rate (FHR) and uterine contractions, is used to predict fetal well-being. Amongst others, fetal heart rate variability (FHRV) is an important indicator of fetal distress. In this study we add FHRV to our previously developed CTG simulation model, in order to improve its use as a research and educational tool. We implemented three sources of variability by applying either 1/f or white noise to the peripheral vascular resistance, baroreceptor output, or efferent vagal signal...

One of the most established roles of oxytocin (OT) is in inducing uterine contractions and labour. Apart from contractions, our recent study have shown that OT can also activate pro-inflammatory pathways in both human myometrial and amnion cells which suggests the pro-inflammatory role of OT should be taken into account when developing tocolytics targeting the OT/OT receptor (OT/OTR) system. The OTR antagonist, Atosiban, is currently used therapeutically for the treatment of PTL. We have previously shown that Atosiban fails to inhibit the pro-inflammatory effects of OT in human amnion, and Atosiban alone activates NF-κB and MAPKs thus upregulating downstream pro-labour genes...

Recent evidence suggests that uterine activation for labor is associated with inflammation within uterine tissues. Hydrogen sulfide (H2S) plays a critical role in inflammatory responses in various tissues. Our previous study has shown that human myometrium produces H2S via its generating enzymes cystathionine-γ-lyase (CSE) and cystathionine-β-synthetase (CBS) during pregnancy. We therefore explored whether H2S plays a role in the maintenance of uterine quiescence during pregnancy. Human myometrial biopsies were obtained from pregnant women at term...

REVIEW

Over the past decade, there have been several studies and reviews on the importance of providing a placental transfusion to the newborn. Allowing a placental transfusion to occur by delaying the clamping of the umbilical cord is an extremely effective method of enhancing arterial oxygen content, increasing cardiac output, and improving oxygen delivery. However, premature and term newborns who require resuscitation have impaired transitional hemodynamics and may warrant different methods to actively provide a placental transfusion while still allowing for resuscitation...

BACKGROUND: Readiness of the cervix is required for successful induction of labor, and there are a number of ways in which this can be achieved. OBJECTIVES: The aim of the present study was to assess whether taking saffron orally could have an effect on the cervical readiness (primary outcome) and some delivery and neonatal outcomes (secondary outcomes) in women in the stage of term pregnancy. PATIENTS AND METHODS: In this double-blind trial, 50 women with a gestational age of 39 to 41 weeks, no indication of cesarean section, a Bishop's score of less than 4, who had plan to have vaginal delivery at Shohada hospital of Bonab, Iran were randomized into two groups receiving three 250mg saffron or placebo pills in 24 hours...

REVIEW

The concept of using a frameless intrauterine device (IUD) instead of the conventional plastic framed IUD is not new. Frameless copper IUDs have been available since the late 1990s. They rely on an anchoring system to retain in the uterine cavity. The clinical experience with these IUDs suggests that frameless IUDs fit better as they are thin and, therefore, do not disturb or irritate the uterus. High tolerance and continuation rates have been achieved as complaints of pain are virtually nonexistent and the impact on menstrual blood loss is minimal...

The uterus is a myogenic organ that is able to produce discrete spontaneous action potentials and contractions without any stimuli. Myometrial excitability is governed by ion channels including Ca(+2) and K(+) channels, but whether or not other channels such as hyperpolarization-activated cyclic nucleotide-gated (HCN) channels, which play an important role in regulating cellular excitability, are also involved has not been reported in uterine smooth muscles. The aim of the present study was to examine whether blocking HCN channels with a specific blocker ZD7288 would modulate the uterine contractility in a rat model...

BACKGROUND: Cardiotocography (CTG) records changes in the fetal heart rate and their temporal relationship to uterine contractions. The aim is to identify babies who may be short of oxygen (hypoxic) to guide additional assessments of fetal wellbeing, or determine if the baby needs to be delivered by caesarean section or instrumental vaginal birth. This is an update of a review previously published in 2013, 2006 and 2001. OBJECTIVES: To evaluate the effectiveness and safety of continuous cardiotocography when used as a method to monitor fetal wellbeing during labour...

OBJECTIVE: There is controversy as to whether maternal body mass index (BMI) influences the contractility of human myometrium in pregnancy. The aim of this study was to examine spontaneous contractile activity of human pregnant myometrium in vitro, with respect to maternal BMI. STUDY DESIGN: Myometrial tissue specimens were obtained at cesarean delivery from 74 women with BMI values ranging from 19 to 50.1 kg m(-2). By recording in vitro from eight strips per donor (590 strips in total), several parameters of spontaneous contractile activity were monitored...

Oxytocin (OT) is a neurohypophysial hormone which has been found to play a central role in the regulation of human parturition. The most established role of oxytocin/oxytocin receptor (OT/OTR) system in human parturition is the initiation of uterine contractions, however, recent evidence have demonstrated that it may have a more complex role including initiation of inflammation, regulation of miRNA expression, as well as mediation of other non-classical oxytocin actions via receptor crosstalk with other G protein-coupled receptors (GPCRs)...

Primary dysmenorrhea (PD) is a common gynecological disorder which, while not life‑threatening, severely affects the quality of life of women. Most patients with PD suffer ovarian hormone imbalances caused by uterine contraction, which results in dysmenorrhea. PD patients may also suffer from increases in estrogen levels caused by increased levels of prostaglandin synthesis and release during luteal regression and early menstruation. Although PD pathogenesis has been previously reported on, these studies only examined the menstrual period and neglected the importance of the luteal regression stage...

Effect of Tramadol infusion (5 mg/ml) on oxytocin-induced uterine contractile activity was studied in chronic experiment on female rabbits with different degrees of biological readiness for parturition. In case of sufficient biological readiness for parturition, Tramadol did not change the number of uterine contractions, but increased the amplitude and duration of each contraction against the background of increased creatine phosphate consumption by the myometrium. At the same time, Tramadol infusion to females without biological readiness for partirition suppressed induced uterine contractile activity by reducing the amplitude of each uterine contraction...

In this prospective cohort study of 286 women undergoing fresh embryo transfer after IVF, uterine contraction frequency and direction were measured before (-5 min), 5 min after (+5 min) and 60 min after (+60 min) embryo transfer. Mean ± SD uterine contraction frequency at -5 min was 1.8 ± 1.1 contractions per min, increasing significantly (P < 0.05) to 2.0 ± 1.1 at +5 min, and returning back to baseline 1.8 ± 1.1 at +60 min. At -5 min, the proportion of women the with retrograde, antegrade, indeterminate direction and absent contractions were 33%, 44%, 17% and 6%; at +5 min, 40%, 42%, 13% and 5%, and at +60 min, 42%, 38%, 14% and 6%...

KIR7.1, an inwardly rectifying K(+) channel, plays a critical role in regulating uterine excitability during pregnancy and has been suggested as a potential new target for the treatment of conditions arising from dysfunctional uterine contractility, for example, atonic postpartum hemorrhage. The aim of this study was to investigate the effects of the selective KIR7.1 blocker, VU590, on both spontaneous and agonist-stimulated contractions of human pregnant myometrium in vitro. At a concentration of 20 µmol/L, VU590 significantly increased the mean contractile force and the frequency of spontaneous contractions ( P < 0...

BACKGROUND: The dural puncture epidural (DPE) technique is a modification of the combined spinal epidural (CSE) technique, where a dural perforation is created from a spinal needle but intrathecal medication administration is withheld. The DPE technique has been shown to improve caudal spread of analgesia compared with epidural (EPL) technique without the side effects observed with the CSE technique. We hypothesized that the onset of labor analgesia would follow this order: CSE > DPE > EPL techniques...
