Labor-Associated Gene Expression in the Human Uterine Fundus, Lower Segment, and Cervix
BACKGROUND Preterm labor, failure to progress, and postpartum hemorrhage are the common causes of maternal and neonatal mortality or morbidity. All result from defects in the complex mechanisms controlling labor, which coordinate changes in the uterine fundus, lower segment, and cervix. We aimed to assess labor-associated gene expression profiles in these functionally distinct areas of the huma...
متن کاملTransvaginal Sonographic Evaluation of the Cervix in Asymptomatic Singleton Pregnancy and Management Options in Short Cervix
Preterm delivery (PTD), defined as birth before 37 completed weeks of gestation, is the leading cause of perinatal morbidity and mortality. Evaluation of the cervical morphology and biometry with transvaginal ultrasonography at 16-24 weeks of gestation is a useful tool to predict the risk of preterm birth in low- and high-risk singleton pregnancies. For instance, a sonographic cervical length (...
متن کاملSonographic evaluation of the lower uterine segment in patients with previous cesarean delivery.
OBJECTIVE To evaluate the appearance of the lower uterine segment (LUS) in pregnant women with previous cesarean delivery and to compare the LUS thickness with that in women with unscarred uteri. METHODS In a prospective study, sonographic examination was performed on 53 pregnant women with previous cesarean delivery (cesarean group), 40 nulliparas (nullip-control), and 40 women who had 1 or ...
متن کاملSonographic lower uterine segment thickness and risk of uterine scar defect: a systematic review.
OBJECTIVE To study the diagnostic accuracy of sonographic measurements of the lower uterine segment (LUS) thickness near term in predicting uterine scar defects in women with prior Caesarean section (CS). DATA SOURCES PubMed, Embase, and Cochrane Library (1965-2009). METHODS OF STUDY SELECTION Studies of populations of women with previous low transverse CS who underwent third-trimester eval...
متن کاملSonographic measurement of the lower uterine segment thickness: is it truly predictive of uterine rupture?
BACKGROUND Sonographic examination of the lower uterine segment (LUS) has been used to diagnose a uterine defect and to determine the degree of LUS thinning in women with previous Caesarean section. Previous studies have demonstrated that the LUS thickness measured sonographically has a high negative predictive value for uterine rupture, suggesting that a normal LUS thickness predicts a safe tr...
