The objective of this commentary is to describe the background, rationale, and methods of the PROLONG (Progestin's Role in Optimizing Neonatal Gestation) trial, which is a multicenter, multinational, placebo-controlled, randomized clinical trial (RCT) designed to assess the safety and efficacy of Makena (hydroxyprogesterone caproate injection, 250 mg/mL) in reducing the risk of preterm birth (PTB) and neonatal morbidity/mortality in women pregnant with a singleton gestation who had a previous singleton spontaneous PTB. The total sample size of the RCT will include 1,707 women. ⋯ Secondary outcomes will include 2-year follow-up of infants. The trial is ongoing and targeted to complete recruitment in 2018.

The Food and Drug Administration's (FDA's) Amendments Act established a legal mandate requiring registration of certain drug, device, and biologics trials in ClinicalTrials.gov prior to patient enrollment. One provision of the act requires investigators to report trial results in ClinicalTrials.gov within 1 year of completion. Preliminary evidence suggests that overall compliance rates are inadequate, and rates specific to obstetrics have not been investigated. ⋯ Half of all applicable obstetrics trials did not report results. Furthermore, rates of compliance appeared to vary by funding source, with trials funded by the National Institutes of Health or industry appearing to have a higher rate of compliance to mandatory data reporting. Greater awareness of federal regulations is needed, and changes should be implemented to increase reporting.

The objective of this study was to investigate whether maternal bronchial asthma increases the risk for long-term respiratory morbidity of the offspring. ⋯ Maternal bronchial asthma is an independent risk factor for long-term respiratory morbidity of the offspring.

Cardiovascular Associations with Abnormal Brain Magnetic Resonance Imaging in Neonates with Hypoxic Ischemic Encephalopathy Undergoing Therapeutic Hypothermia and Rewarming.
This article compares hemodynamic characteristics of neonates with hypoxic ischemic encephalopathy (HIE) receiving therapeutic hypothermia (TH) with normal versus abnormal brain magnetic resonance imaging (MRI). ⋯ Longitudinal changes in cardiac output were noted in neonates with HIE during TH and rewarming. Echocardiography evidence of PH, however, was associated with abnormal MRI brain. The prognostic relevance of these physiologic changes requires more comprehensive delineation.
