OBJECTIVE We sought to determine the proportion of evidence-based (EB), vs non-EB (NEB) iatrogenic late preterm birth, and to compare corresponding rates of neonatal intensive care unit (NICU) admission. STUDY DESIGN We performed a retrospective cohort study. Cases were categorized as EB or NEB. NICU admission was compared between groups in both univariate and multivariate analysis. RESULTS Of 2693 late preterm deliveries, 32.3% (872/2693) were iatrogenic; 56.7% were delivered for NEB… Expand
Short-term neonatal outcomes in diamniotic twin pregnancies delivered after 32 weeks and indications of late preterm deliveries.
TLDR
The data demonstrate a high rate of late preterm birth among twin pregnancies, with over half of nonspontaneous early deliveries due to NEB indications, and underscores the need for systematic evaluation of indications for delivery in LPTB twin deliveries. Expand
Avoiding late preterm deliveries to reduce neonatal complications: an 11-year cohort study
TLDR
Efforts should be made to avoid non-spontaneous LPT births in order to reduce neonatal complications, particularly after non-evidence-indicated LPT birth. Expand

TLDR
LPT infants are more likely to require positive-pressure ventilation support and incur a longer duration of intubation than term infants, and a trend towards greater mortality is prevalent compared to term infants. Expand
Original Article Late preterm birth: an iatrogenic epidemic
TLDR
Almost one fifth of LPTB, and its neonatal sequelae, may be avoidable, and the recorded diagnoses 'placenta pre- via', 'oligohydramnios', 'preeclampsia', 'maternal disease', and 'placental abruption' were most likely to fail to meet criteria for generally accepted indication after review of primary medical records.

Impact of the new guidelines on the management of premature rupture of membranes for the prevention of late preterm birth: an 11-year retrospective study
TLDR
Adoption of new guidelines for the management of PPROM will prevent a considerable number of LPT births and help decrease the adverse effects and potential disability associated with late preterm infants. Expand
Iatrogenic and spontaneous late preterm twins - which are at higher risk of neonatal complications?
TLDR
The primary outcomes of the study were various neonatal adverse events, including one of the following per pregnancy: admission to Neonatal Intensive Care Unit (NICU), respiratory disorders (RD) and pneumonia, intraventricular hemorrhage (IVH), sepsis, NEC and jaundice requiring phototherapy. Expand
Maternal risk factors and obstetric complications in late preterm prematurity.
TLDR
Maternal risk factors and obstetric complications are significantly higher in LPTB than in term births and these factors should be considered to identify women at risk for either spontaneous or medically-indicated L PTB. Expand
Morbidity in Late Preterm Birth: A Retrospective Cohort Study Assessing the Role of Immaturity versus Antecedent Factors
TLDR
This study found no difference in morbidity risk related to 3 common antecedents of preterm birth in LPIs, suggesting that immaturity is the primary factor in determining adverse outcomes, intensified by factors resulting in prematurity. Expand
Antenatal corticosteroids in the late preterm period: A prospective cohort study.
TLDR
Administration of antenatal corticosteroids to parturients at risk of imminent delivery during the late preterm period does not appear to reduce short-term neonatal morbidities. Expand
Iatrogenic and spontaneous late preterm twins--which are at higher risk of neonatal complications?
TLDR
Late prematurity in twin pregnancies is associated with higher risk of neonatal morbidity than in term twins, and Iatrogenic late pre term birth increases the risk of NICU admission and respiratory disorders in neonates in comparison to spontaneous late preterm birth. Expand

Late preterm birth: how often is it avoidable?
TLDR
The frequency of potentially avoidable late preterm birth deliveries at a tertiary care medical center is estimated and it is concluded that <10% of LPTB are purely elective and >80% are clearly unavoidable. Expand
Contemporary management of monochorionic diamniotic twins: outcomes and delivery recommendations revisited.
TLDR
In the absence of a clinical indication for delivery, these data do not support elective preterm delivery for prevention of intrauterine fetal demise in uncomplicated MCDA twins. Expand
Indications for delivery and short-term neonatal outcomes in late preterm as compared with term births.
TLDR
Rates of neonatal intensive care unit admission, length of stay, and neonatal morbidities are significantly higher in late preterm as compared with term births. Expand
Delivery Indications at Late-Preterm Gestations and Infant Mortality Rates in the United States
TLDR
It is concerning that these infants had higher mortality rates compared with those born after spontaneous labor at similar gestational ages, and patients and providers need to discuss the risks of delivering a preterm infant in the absence of medical indications at 34 to 36 weeks. Expand
Respiratory morbidity in late preterm births.
TLDR
In a contemporary cohort of deliveries in the United States, late preterm birth, compared with term delivery, was associated with increased risk of respiratory distress syndrome and other respiratory morbidity. Expand
Late-Preterm Birth: Does the Changing Obstetric Paradigm Alter the Epidemiology of Respiratory Complications?
TLDR
Reduced respiratory morbidity associated with decreased births after 40 weeks were offset by the adverse respiratory effect of increased cesarean delivery rates and increased late-preterm birth rates over the 9-year study period. Expand
Author response to: Increased perinatal morbidity in monochorionic versus dichorionic twin pregnancies: clinical implications of a large Dutch cohort study
TLDR
Suggestions are persist suggesting that planned delivery at 36–37 weeks of gestation seems to be justified for monochorionic (MC) twinning, and about the discrepancy between estimated fetal weights and actual birthweights in a MC case, discussed in this paper. Expand

OBJECTIVE: To compare outcomes among neonates delivered after documentation of fetal lung maturity before 39 weeks and those delivered at 39 or 40 weeks. METHODS: This was a retrospective cohortExpand
Neonatal Mortality and Morbidity Rates in Late Preterm Births Compared With Births at Term
TLDR
Late preterm births are common and associated with significantly increased neonatal mortality and morbidity compared with births at 39 weeks, and preterm labor was the most common cause. Expand

TLDR
It is suggested that healthy late preterm infants compared with healthy term infants face a greater risk for developmental delay and school-related problems up through the first 5 years of life. Expand
