: To evaluate whether neonates born to women who previously had received antenatal corticosteroids and then delivered a late-preterm-birth neonate had less respiratory morbidity compared with those not exposed to antenatal corticosteroids.
: This is a secondary analysis from a multicenter observational study regarding mode of delivery after previous cesarean delivery. We compared women who received one course of antenatal corticosteroids with unexposed parturients and evaluated various respiratory outcomes among those having a singleton, late-preterm-birth neonate. We controlled for potential confounders including gestational age at delivery, diabetes, mode of delivery, and maternal race.
: Five thousand nine hundred twenty-four patients met the inclusion criteria; 550 received steroids and 5,374 did not. In the univariable model, compared with unexposed women, those who received antenatal corticosteroids appeared more likely to have neonates who required ventilatory support (11.5% compared with 8.6%, P=.022), had respiratory distress syndrome (RDS) (17.1% compared with 12.2%, P=.001), developed transient tachypnea of the newborn (12.9% compared with 9.8%, P=.020), or required resuscitation in the delivery room (55.8% compared with 49.7%, P=.007). After controlling for confounding factors, we found no significant differences among the groups regarding all of the above outcomes with an odds ratio for RDS of 0.78 (95% confidence interval, 0.60-1.02) and ventilator support of 0.75 (95% confidence interval, 0.55-1.03).
: Exposure to antenatal corticosteroids does not significantly affect respiratory outcomes among those with a subsequent late-preterm birth. LEVEL OF

Compare the effect of antenatal corticosteroids (ACS) on neonatal outcomes among singleton and twin pregnancies and the impact of completeness and timing of ministration.
To study the neonatal respiratory morbidity in late-preterm neonates.
Rationale/Objectives: To identify antenatal risk factors associated with increased risk for BPD and respiratory disease during early childhood after preterm birth, we performed a prospective, longitud...
Efficacy of antenatal corticosteroids before 25 weeks of gestation is unclear.
In spite of the recommendation for rescue antenatal corticosteroids (ACS), the optimal time interval between primary and rescue courses has not been clearly demonstrated. The aim of this study was to ...
This study will review records of women who broke their water early who received a repeat course of antenatal steroids.
Antenatal corticosteroids result in substantial decrease in neonatal morbidity and mortality by specifically reducing the risk of respiratory distress syndrome, intraventricular hemorrhage...
Administration of corticosteroids is standard practice for pregnant patients at risk of preterm labour to reduce the risk of neonatal respiratory distress syndrome, intraventricular hemorr...
To determine the effect of corticosteroids, administered 24 to 48 hours before parturition, on the incidence of neonatal respiratory distress syndrome (RDS) and to determine whether the th...
This study aims to determine the effectiveness of antenatal corticosteroid therapy in late preterm babies. The investigators hypothesis is corticoid accelerates fetal lung maturation even ...
A syndrome characterized by outbreaks of late term abortions, high numbers of stillbirths and mummified or weak newborn piglets, and respiratory disease in young unweaned and weaned pigs. It is caused by PORCINE RESPIRATORY AND REPRODUCTIVE SYNDROME VIRUS. (Radostits et al., Veterinary Medicine, 8th ed, p1048)
A group of corticosteroids carrying hydroxy groups, usually in the 11- or 17-positions. They comprise the bulk of the corticosteroids used systemically. As they are relatively insoluble in water, salts of various esterified forms are often used for injections or solutions.
The effect of GLOBAL WARMING and the resulting increase in world temperatures. The predicted health effects of such long-term climatic change include increased incidence of respiratory, water-borne, and vector-borne diseases.
An effect usually, but not necessarily, beneficial that is attributable to an expectation that the regimen will have an effect, i.e., the effect is due to the power of suggestion.
A group of CORTICOSTEROIDS primarily associated with the water and electrolyte balance. This is accomplished through the effect on ION TRANSPORT in renal tubules, resulting in retention of sodium and loss of potassium. Mineralocorticoid secretion is itself regulated by PLASMA VOLUME, serum potassium, and ANGIOTENSIN II.
