[EX Q]: Question: Does surfactant replacement therapy on ECMO improve outcome in neonates with congenital diaphragmatic hernia?
Answer: The data from this study suggest that surfactant replacement on ECMO for neonates with congenital diaphragmatic hernia does not provide significant benefit in the infant's clinical course with respect to survival, length of ECMO course, length of intubation, or subsequent need for supplemental oxygen.
[EX A]: no

[EX Q]: Question: Are polymorphisms in SPINK5 associated with asthma in a Dutch population?
Answer: The negative results in this study suggest that SPINK5 is not associated with asthma or atopic phenotypes in individuals ascertained by a proband with asthma. This is consistent with the finding that SPINK5 is not expressed in the lung. Because our patients were ascertained for asthma, a role of SPINK5 in atopic dermatitis cannot be excluded.
[EX A]: no
