Do age and alarm symptoms predict endoscopic findings among patients with dyspepsia : a multicentre database study?
Age and the presence of "alarm" symptoms are not effective predictors of endoscopic findings among patients with dyspepsia. Better clinical prediction strategies are needed to identify patients with significant upper gastrointestinal pathology.
Aging does not affect bronchodilator response to beta-agonist after methacholine-induced bronchoconstriction. The responsiveness to beta-agonist alone is similar to the responsiveness to the combination of beta-agonist and anticholinergic agent in all age groups.
