Fetal acidemia during labor is associated with an increased risk of brain injury and lasting neurological deficits. This is in part due to the repetitive occlusions of the umbilical cord (UCO) induced by uterine contractions. Whereas fetal heart rate (FHR) monitoring is widely used clinically, it fails to detect fetal acidemia. Hence, new approaches are needed for early detection of fetal acide...

Previous research showed that age-related division of labor in honey bees is associated with changes in activity rhythms; young adult bees perform hive tasks with no daily rhythms, whereas older bees forage with strong daily rhythms. We report that this division of labor is also associated with differences in both circadian rhythms and mRNA levels of period, a gene well known for its role in ci...

Poor women with children in Ecuador were selected at random for a cash transfer equivalent to 7 percent of monthly expenditures. The transfer is greater than the increase in schooling costs at the end of primary school, but it is less than 20 percent of median child labor earnings in the labor market. Poor families with children in school at the time of the award use the extra income to postpon...

OBJECTIVE Spontaneous labor at term involves the activation of placental corticotropin-releasing hormone and the fetal adrenal axis, but the basis for extreme preterm labor is unknown. Our objective was to determine whether placental corticotropin-releasing hormone is activated in extreme preterm labor. STUDY DESIGN One thousand five hundred six mothers delivering at less than 28 weeks' gesta...

This report aimed at presenting a case which evolved to meningitis after combined labor spinal-epidural analgesia. CASE REPORT Laboring patient, 25 years old, second gestation and previous c-section. Combined labor spinal-epidural analgesia was induced with double-puncture. Twenty-four hours ...

OBJECTIVE To examine the value of combining cervical length and maternal characteristics in a prolonged-pregnancy clinic in the prediction of the probability of firstly, spontaneous onset of labor within the subsequent 10 days and secondly, the need for Cesarean section. METHODS This was a prospective study of women with singleton pregnancies attending an ultrasound-based prolonged-pregnancy ...

the use of corticosteroids is one of the methods put forward for the strengthening and speeding up the process of labor. after identification of glucocorticoid receptors in human amnion, the role of corticosteroids in starting the process of labor has been studied in numerous studies.the purpose of this study was to determine the effect of intravenous dexamethasone on preparing the cervix and o...

This paper studies the importance of labor supply responses in enabling households to smooth consumption in the face of crop loss. The 1993 Indonesian Family Life Survey is unusual because it contains self-reported information on crop loss and on household responses to crop loss. 41.6 percent of households who reported a crop loss also reported that they responded by increasing their labor supp...

OBJECTIVE To review the outcome of induction of labor with vaginal prostaglandin-E2 in grand multiparous women with one previous cesarean section. METHODS Twenty-six grand multiparous women with one previous cesarean section were induced with vaginal prostaglandin-E2. RESULTS Twenty (76.9%) women delivered vaginally and six (23.1%) women delivered by emergency cesarean section. The mean dur...
