  • Prevention of Preterm Birth Based on Short Cervix: Symptomatic Women With Preterm Labor or Premature Prelabor Rupture of Membranes SEMINARS IN PERINATOLOGY Ness, A. 2009; 33 (5): 343-351

    Abstract

    The diagnosis of preterm labor (PTL) is challenging, especially in women whose cervical dilatation is <2 cm and who are <80% effaced. In symptomatic women, with threatened PTL in both singletons and twins, transvaginal ultrasound cervical length (CL) identifies a high-risk group that is more likely to be in true PTL, more likely to deliver sooner, and more likely to deliver preterm. The addition of fetal fibronectin improves the predictive accuracy in women whose CL is <30 mm but >15 mm. Transvaginal ultrasound CL can also be performed in the presence of ruptured membranes and predicts latency. Although additional data are needed, the evidence so far suggests that the use of transvaginal ultrasound CL and fetal fibronectin can be used to better identify and manage women with PTL likely to have an imminent preterm delivery, and to avoid interventions in women who would not.

  • Does knowledge of cervical length and fetal fibronectin affect management of women with threatened preterm labor? A randomized trial AMERICAN JOURNAL OF OBSTETRICS AND GYNECOLOGY Ness, A., Visintine, J., Ricci, E., Berghella, V. 2007; 197 (4)

    Abstract

    The purpose of this study was to estimate the effect of sonographic cervical length (CL) and fetal fibronectin (FFN) on length of evaluation and outcomes in women with preterm labor (PTL).Women with threatened PTL were randomized to either a knowledge group (results of CL and FFN available and used according to study protocol), or a standard group (blinded to CL and FFN). Primary outcome was length of evaluation in triage.One hundred women were randomized. There was no significant difference between groups in length of evaluation, but in women with CL > or = 30 mm, the mean time for evaluation was significantly shorter in the knowledge group (1:58 h +/- 0:50 vs 2:53 h +/- 0:50, P = .004). Incidence of spontaneous preterm birth (SPTB) in the knowledge group was significantly reduced (13.0 vs 36.2%, P = .01).The knowledge of CL and FFN was associated with reduction in length of evaluation in women with CL > or = 30 mm and in incidence of SPTB in all women with PTL.

  • Gestational age at cervical length measurement and incidence of preterm birth OBSTETRICS AND GYNECOLOGY Berghella, V., Roman, A., Daskalakis, C., Ness, A., Baxter, J. K. 2007; 110 (2): 311-317

    Abstract

    To estimate the risk of spontaneous preterm birth based on transvaginal ultrasound cervical length and gestational age at which cervical length was measured.Women at high risk for spontaneous preterm birth and with transvaginal ultrasound cervical length measurements between weeks 12 and 32 were identified at one institution between July 1995 and June 2005. Inclusion criteria for women at high risk for spontaneous preterm birth were prior spontaneous preterm birth at 14 to 35 weeks, cone biopsy, müllerian anomaly, or two or more dilation and evacuations. Women with multiple gestations, cerclage, indicated preterm birth, or fetal anomalies were excluded. Logistic regression was used to estimate the spontaneous preterm birth risk before 35, 32, and 28 weeks.Seven hundred five women received 2,601 transvaginal ultrasound measurements for cervical length. The incidences of spontaneous preterm birth before 35, 32, and 28 weeks were 17.7, 10.6, and 6.7%, respectively. The risk of spontaneous preterm birth before 35 weeks decreased by approximately 6% for each additional millimeter of cervical length (odds ratio 0.94, 95% confidence interval, 0.92-0.95, P=.001) and by approximately 5% for each additional week of pregnancy at which the cervical length was measured (odds ratio 0.95, 95% confidence interval 0.92-0.98, P=.004). Similar results were obtained for spontaneous preterm birth before 32 and 28 weeks.Gestational age at which transvaginal ultrasound cervical length is measured significantly affects the calculation of risk of spontaneous preterm birth. The spontaneous preterm birth risk increases as the length of the cervix declines and as the gestational age decreases. These spontaneous preterm birth risks are important for counseling and management for women with various degrees of short cervical length at different gestational ages.II.

  • Very-low-birthweight neonates: Do outcomes differ in multiple compared with singleton gestations? AMERICAN JOURNAL OF PERINATOLOGY Hayes, E. J., Paul, D., Ness, A., Mackley, A., Berghella, V. 2007; 24 (6): 373-376

    Abstract

    The purpose of this study is to determine if outcomes for very-low-birthweight (VLBW) neonates differ in multiple versus singleton gestations. This is a retrospective cohort study of neonates weighing less than 1500 g admitted to a neonatal intensive care unit from 1993 to 2004. Outcome variables were necrotizing enterocolitis, death, and/or severe intraventricular hemorrhage (IVH). Statistical analysis included univariate and multivariate analysis. During the study period, 1769 VLBW infants including 465 multiples and 1304 singletons were identified. Gestational age and birthweight were similar; conversely white race (68% multiples versus 43% singletons), maternal age (28.7 +/- 5.7 versus 26.1 +/- 6.5 years), born at facility (95% versus 86%), antenatal steroids (74% versus 58%), preeclampsia (14% versus 24%), and preterm labor (74% versus 62%) were significantly different. Correcting for these, VLBW multiples had a higher odds ratio (OR) of death and/or severe IVH, OR 1.4 (1.03-1.95). In our population, VLBW multiple gestations were at elevated odds for death and/or severe IVH compared with VLBW singletons.

  • Impact of the recent randomized trials on the use of progesterone to prevent preterm birth: A 2005 follow-up survey AMERICAN JOURNAL OF OBSTETRICS AND GYNECOLOGY Ness, A., Dias, T., Damus, K., Burd, I., Berghella, V. 2006; 195 (4): 1174-1179

    Abstract

    The purpose of this study was to determine whether current attitudes regarding the use of progesterone to prevent preterm birth have changed since our last survey in 2003.We mailed a 20 question survey to 1264 board certified Maternal-Fetal Medicine specialists in the United States between February and March of 2005 asking about their use and attitudes regarding progesterone to prevent preterm birth.Five hundred and seventy-two surveys were returned (response rate of 45%). In 2005, 67% of respondents used progesterone to prevent SPTB, compared to 38% in 2003 (P < .001). Among users, 38% recommended progesterone for indications other than previous SPTB. Users were more concerned about lack of insurance coverage compared to nonusers but nonusers were more concerned about safety, efficacy, need for more data, and long-term neonatal effects.Although the use of progesterone to prevent PTB has increased significantly since our last survey, there remain a substantial number of nonusers. Among users, many are using it for indications not yet proven in clinical trials. Current nonusers have higher levels of concerns compared to nonusers in the first survey and their major concern is the need for more data.

  • Progesterone for preventing premature birth - Practice patterns of board-certified maternal-fetal medicine specialists in the United States JOURNAL OF REPRODUCTIVE MEDICINE Ness, A., Baxter, J., Hyslop, T., Berghella, V. 2006; 51 (5): 411-415

    Abstract

    To determine the current prescription of progesterone to prevent preterm birth (PTB) among board-certified maternal-fetal medicine (MFM) specialists in the United States.A survey of the board-certified MFM specialists in the United States examining their prescription of and attitudes regarding progesterone to prevent PTB 6 months following publication of a National Institute for Child Health and Human Development trial.Of 1,264 questionnaires sent, 526 were returned (response rate, 42%). After exclusions, 522 surveys remained. One hundred ninety-eight (38%) respondents prescribed progesterone, and 324 (62%) did not. Most nonprescribers were awaiting more data and were more concerned than prescribers about long-term effects (p < 0.0001). Twenty percent of prescribers prescribed progesterone for women with current signs or symptoms of preterm labor.As a result of recent evidence, over one third of MFM specialists surveyed have begun prescribing progesterone to prevent PTB. Of these specialists, 20% are using it for indications other than a prior PTB.
