OBJECTIVE: Pre-eclampsia, growth retardation and preterm delivery are the most common reasons leading to increased maternal and perinatal mortality. The increased expression of hypoxia induced factors, such as HIF-1, triggers the overexpression of anti-angiogenic genes. The aim of this study was to determine the transcriptional activity of individual pro- and anti-angiogenic markers (VEGF, HIF-1, sEng, Flt-1, PlGF-1) in maternal blood samples from patients with spontaneous preterm labor, preterm labor in combination with pre-eclampsia and fetal growth restriction in comparison with physiologically terminated pregnancies...

Importance: Actinomyces is commonly found in many areas of the body where it derives a benefit without harming the host. When it does infect the host during pregnancy, is that infection a threat to the obstetric patient and does that infection cause adverse pregnancy outcomes? Objective: The aim of this study was to review what is known about Actinomyces infections and the impact of an Actinomyces infection on pregnancy outcomes. Evidence Acquisition: A PubMed search was undertaken with the search years unlimited to April 1, 2016, and restricted to articles in English...

Importance: Preterm birth is a major contributor to perinatal morbidity and mortality. The most common intervention performed to improve perinatal outcomes for a woman experiencing cervical dilation in the second trimester without signs or symptoms of preterm labor is the cerclage. Objective: We sought to review and compare available national guidelines on cerclage use. Evidence Acquisition: We performed a descriptive review of 3 national guidelines on cerclage: The American Congress of Obstetricians and Gynecologists Practice Bulletin on "Cerclage for the Management of Cervical Insufficiency," Green-top Guideline from the Royal College of Obstetricians and Gynaecologists entitled "Cervical Cerclage," and the Society of Obstetricians and Gynaecologists of Canada Clinical Practice Bulletin entitled "Cervical Insufficiency and Cervical Cerclage...

In 2015, the Society for Maternal Fetal Medicine (SMFM) developed a low risk for cesarean delivery definition based on administrative claims-based diagnosis codes described by the International Classification of Disease, Clinical Modification, 9(th) revision. The SMFM definition is a clinical enrichment of two available measures from the Joint Commission (JC) and the Agency for Healthcare Research and Quality (AHRQ) measures. The SMFM measure excludes diagnosis codes that represent clinically relevant risk factors that are absolute or relative contraindications to vaginal birth while retaining diagnosis codes such as labor disorders that are discretionary risk factors for cesarean delivery...

Obesity is a global health problem even among pregnant women. Obesity alters quality of labor, such as preterm labor, prolonged labor, and higher oxytocin requirements in pregnant women. The most important factors to play a role in the altered gestational period and serve as drug targets to treat the consequences are female sexual hormones, calcium channels, adrenergic system, oxytocin, and prostaglandins. However, we have limited information about the impact of obesity on the pregnant uterine contractility and gestation time...

Controlling labor pain is one of the basic goals for caregivers during the birthing process. There are many pharmacological and nonpharmacological methods that are used for controlling pain and helping the mother to cope with pain and have a favorable labor. The study was planned as a randomized, controlled experimental study to detect the effect of acupressure applied to Point LI4 on perceived labor pains. The study sample comprised 88 pregnant women (44 acupressure group, 44 control group), who complied with the study guidelines, agreed with the conditions of the study, and signed the informed consent...

BACKGROUND: An overview of labor based only on epidemiological data cannot identify or explain the mechanisms involved in childbirth. Data about the position that women should take in giving birth are discordant. None of the studies of birth positions adequately define or describe them or their biomechanical impact (pelvic orientation, position of the back). The measurement of the effect of one position relative to that of another requires precise definitions of each position and of their maternal biomechanical consequences, as well as safe measurement methods...

In term breech deliveries, vaginal delivery can be safely envisioned in some conditions (related to patient selection and obstetrician experience). Very few data are currently available, however, about the possibility of inducing labor in these situations. OBJECTIVE: To assess the effectiveness and safety of induction of labor for breech presentations. STUDY DESIGN: Retrospective comparative hospital-based study of a continuous series of term breech deliveries from 2000 to 2010...

BACKGROUND: Most very low birth weight (VLBW, birth weight <1500 g) infants receive empiric antibiotics for risk of early-onset sepsis (EOS). The objective of this study was to determine the characteristics of VLBW infants with culture-confirmed EOS at a single center during 25 years and to identify opportunities for antibiotic stewardship. METHODS: Retrospective cohort study includes VLBW infants admitted from 1990 to 2015. EOS was defined as isolation of a pathogen in blood or cerebrospinal fluid culture obtained at <72 hours of age...

Major clinical challenges for obstetricians and neonatologists result from early cervix remodeling and preterm birth. Complications related to cervix remodeling or delivery account for significant morbidity in newborns and peripartum mothers. Understanding morphology and structure of the cervix in pregnant women is limited mostly to the period soon before and after birth. However, evidence in rodent models supports a working hypothesis that a convergence of factors promotes a physiological inflammatory process that degrades the extracellular collagen matrix and enhances biomechanical distensibility of the cervix well before the uterus develops the contractile capabilities for labor...

Introduction At term, fetal weight estimation is an important factor for decisions about the delivery mode and the timing of labor induction. This study aimed to compare the accuracy of abdominal palpation with that of ultrasound performed by different examiners to estimate fetal weight. The study investigated whether differences in the examiners' training affected fetal weight estimates. The accuracy of the weight estimates made for fetuses with extreme birth weights was also evaluated. Finally, the accuracy of Johnson's method and of Insler and Bernstein's formula for estimating fetal weight were compared with the other two methods...

BACKGROUND: Cesarean delivery is being increasingly used by obstetricians for indicated deliveries in the second stage of labor. Unplanned extension of the uterine incision involving the cervix often occurs with these surgeries. Therefore, we hypothesized that cesarean delivery in the second stage of labor may increase the rate of subsequent spontaneous premature birth. OBJECTIVE: We sought to determine if cesarean delivery in the late first stage of labor or in the second stage of labor increases the risk of a subsequent spontaneous preterm birth...

Context: Biochemical weakening of the amnion is a major factor preceding preterm premature rupture of membranes (PPROMs), leading to preterm birth. Activation of matrix metalloproteinases (MMPs) is known to play a key role in collagen degradation of the amnion; however, epithelial to mesenchymal transition (EMT) that is also induced by MMP activation has not been investigated as a mechanism for amnion weakening. Objective: To measure amniotic EMT associated with vaginal delivery (VD) compared with unlabored cesarean sections (CSs), and to assess changes in amniotic mechanical strength with pharmacologic inhibitors and inducers of EMT, thus testing the hypothesis that EMT is a key biochemical event that promotes amniotic rupture...
