“…2 Late preterm infants account for approximately 70% of all born prematurely in the United States, 3 where the percentage of late preterm infants, among those born alive, was 6.3% in 1981 and 8.8% in 2003. 4 In Canada, the percentage increased by 6% from 1985 to 1989 and 1990 to 1996 5 and in Denmark, there was a 22% rise in those born between 32 and 36 gestational weeks from 1995 to 2004. 6 In Brazil, it is estimated that 140 000 births of late preterm infants occur per year, corresponding to approximately 70% of the preterm infants and 4.6% of all liveborn infants.…”

Objective: Evaluate the need for resuscitative procedures at birth, in late prematures.Study Design: This prospective cohort study enrolled all liveborn infants from 1 to 30 September 2003, with 34 to 41 weeks of gestation without congenital anomalies, born in 35 public hospitals of 20 Brazilian state capitals. Logistic regression analyzed variables associated with the need for bag and mask ventilation.Result: Of the 10 774 infants studied, 1054 were late preterms and 485 required resuscitative measures. Of the 1054, 338 (32%) received only free-flow oxygen, 143 (14%) were bag and mask ventilated, 27 (3%) were intubated and 10/27 received chest compressions and/or medications. Bag and mask ventilation in late preterms was associated with twin gestation, maternal hypertension, nonvertex presentation, cesarean delivery and lower gestational age.Conclusion: Improving control of maternal hypertension, prolonging gestation for 1 to 2 weeks and restricting operative deliveries could decrease the need of resuscitation of late preterms at birth.

“…Although late-preterm births account for about two-thirds of all pre-term births (10) , less is known about the longer-term outcomes of this group in comparison to other preterm groups. The relative dearth of studies that investigated developmental outcomes in late preterm infants may be the consequence of the fact that this group of infants are not routinely followed-up after neonatal intensive care (15) .…”

“…Current definitions from the World Health Organization differentiate extremely preterm (born ≤27 weeks gestation) from very preterm (born 28 to 31 weeks gestation (9) ). Other preterm infants can be categorised in moderate (born 32 to 33 weeks gestation (10,11) ), and late-preterm or mild-preterm (born at 34 to 36 weeks gestation (10,11) ). Modified versions of the PARCA-R displayed concurrent validity with the Bayley Scales of Infant Development-II Mental Development Index in very preterm (12) , moderate preterm (13) , as well as late and moderately preterm toddlers (14) at age two years.…”

“…[1][2][3] Despite advances in obstetric care, preterm births continue to constitute about 8 to 12% of all births. 4,5 Hospitalization for preterm contractions with suspected imminent preterm delivery poses a major burden on health services, and costs and accounts for more than one-third of obstetric admissions before delivery.…”

PAPP-A levels as an early marker of idiopathic preterm birth: a pilot study

et al. 2007

View full text Add to dashboard Cite

Objective: To evaluate late PAPP-A levels as predictive of preterm birth in symptomatic women.Study Design: Prospective cohort study of singleton gestations, 23 to 34 weeks, and symptoms of preterm labor. PAPP-A, IGF-I and IGF-III analysis were performed. Primary end point was delivery p7 days. Accuracy and optimally predictive PAPP-A values were based on receiver operator characteristic (ROC) curves.Result: In all, 26 women (51%) delivered p7 days post-admission (Group 1); 25 women (49%) >7 days (Group 2). Group 1 mean PAPP-A ¼ 38 000 vs 55 333 for Group 2 (P<0.04). Group 1 mean gestational age at delivery ¼ 29 weeks vs 37 weeks for Group 2 (P<0.00014). PAPP-A level p30 000 mU l À1 had highest specificity (88%), sensitivity (50%), and positive predictive (81%) and negative predictive (62%) values for delivery p7 days. ROC area under curve ¼ 0.703.Conclusion: PAPP-A levels p30 000 mU l À1 at admission was associated with increased risk for preterm birth p7 days, supporting active management and therapeutic approach in these women.
