Cesarean section rates continue to increase globally. Prediction of intrapartum cesarean section could lead to preventative measures. Our aim was to assess the association between sonographically measured cervical length at 37 weeks' gestation and cesarean section among women planning a vaginal birth. The population was women with a low risk pregnancy or with gestational diabetes MATERIAL AND METHODS: This was a prospective cohort study conducted in a tertiary referral hospital in Sydney, Australia. 212 women with a low risk pregnancy or with gestational diabetes were recruited including 158 nulliparous and 54 parous women...

BACKGROUND: Preterm delivery is the major cause of adverse outcomes in twin pregnancy. A shortened cervix at 20-24 weeks of amenorrhea is a good predictor of preterm birth in asymptomatic patients. However, there are no recommendations for serial cervical length measurements for these high risk pregnancies. OBJECTIVES: To evaluate the benefits from monthly cervical length monitoring in asymptomatic twin pregnancies. METHODS: This was a prospective study...

Background & objectives: Data on serial cervical length (CL) measurements in pregnancy at term to predict spontaneous labour onset are scarce and conflicting. This study was conducted to observe CL changes preceding spontaneous onset of labour, by serial transvaginal sonography (TVS) and transabdominal sonography (TAS), in nulliparous Indian women near term. Methods: Only nulliparous women with a singleton foetus in cephalic presentation and who confirmed their gestational age were recruited...

The number of elective abortions has been stable for several decades. Many factors explain women's choice of abortion in cases of unplanned pregnancies. Early initiation of contraceptive use and a choice of contraceptive choices appropriate to the woman's life are associated with lower rates of unplanned pregnancies. Reversible long-acting contraceptives should be favored as first-line methods for adolescents because of their effectiveness (grade C). Ultrasound scan before an elective abortion must be encouraged but should not be obligatory (professional consensus)...

OBJECTIVE: To investigate whether adherence to a cervical length-based protocol can reduce both unnecessary admissions and the socioeconomic costs associated with inappropriately admitted patients. METHOD: The present retrospective observational study included women admitted for threatened preterm labor (TPL) at 24-34 weeks of pregnancy to a tertiary hospital in the Canary Islands, 2009-2014. Data were reviewed from all patients admitted for TPL. Those with a long cervix (>25 mm) were classified as "inappropriate admissions", and both the economic burden based on diagnosis-related group (DRG) and the social costs associated with sick leave for these women were calculated...

AIM: To establish how useful and the predictive capacity of uterocervical angles (UCA) in the termination of second trimester pregnancies. MATERIAL AND METHODS: This prospective cohort study was conducted at a tertiary center with a total of 120 singleton pregnancies delivered between 14 and 24 gestational weeks. Before the beginning of misoprostol induction, patients were screened for both cervical length (CL) and uterocervical angles (UCA). The UCA is defined as an angle constructed by the measurement of the cervical canal and lower uterine segment...

BACKGROUND: It is unknown if universal second-trimester transvaginal ultrasound (TVU) cervical length (CL) screening in asymptomatic women with singleton gestations and no prior spontaneous preterm birth (SPTB) affects the incidence of symptoms of preterm labor (PTL) later in pregnancy. OBJECTIVE: To evaluate the incidence of threatened PTL before and after the implementation of universal second trimester TVU CL screening. STUDY DESIGN: This was a retrospective cohort study of all consecutive singleton gestations without prior SPTB presenting to obstetric triage for threatened PTL between 23 0/7 and 33 6/7 week in 2011 (1 January-31 December), and in 2014 (1 January-31 December) at Thomas Jefferson University Hospital (TJU) (Philadelphia, PA)...

One in 10 infants in the United States is delivered preterm (ie, before the 37th week of pregnancy), contributing to the significant burden on the national healthcare system. Nevertheless, a lack of agreement continues among obstetric professional societies on guidelines for standardization of the approach to the diagnosis and management of patients with symptoms of preterm labor (PTL). This disparity in consensus has likely resulted in poor identification of women at an increased risk for preterm birth (PTB)...

BACKGROUND: A midtrimester cervical length (CL) <25 mm is associated with spontaneous preterm birth (sPTB). However, as CL ≥25 mm is not enough to exclude recurrence in high-risk patients, follow-up CL measurement later in pregnancy has been proposed. OBJECTIVES: To evaluate whether CL measurement at 26±1 weeks in asymptomatic high-risk patients improves the prediction of sPTB recurrence. METHODS: A retrospective cohort of high-risk women because of previous sPTB was analyzed...
