Input: Question: Is acute pulmonary exacerbation associated with increased energy expenditure in children with cystic fibrosis?
Answer: These data suggest that an acute pulmonary exacerbation is not associated with an increase above a subject's baseline REE in children with cystic fibrosis with mild to moderate lung disease. Management of an acute pulmonary exacerbation should be associated with sustained improvement in pulmonary function and nutritional status; in contrast, weight loss or failure to improve pulmonary function should be seen as atypical.
Output:
no
