tion time measurements, at the beginning of their shift, and at the end of the same 12-hour shift. Among day-shift nurses, the reaction times were unchanged across the shift; however, night-shift nurses performed better on reaction tests towards the end of the shift.

ESSENTIAL AMINO ACIDS MAY IMPROVE STRENGTH IN COPD PATIENTS
(Wednesday, October 29, 1:00 PM EST)

Patients with chronic obstructive pulmonary disease (COPD) may improve muscle strength and exercise endurance by taking essential amino acid supplements. For 3 months, researchers from Italy treated 20 patients with stage 3 and 4 COPD with 8 g of essential amino acids plus usual pharmacologic treatment. Compared with 20 patients in the matched control group, after 3 months, patients in the study group showed a statistically significant increase of muscle strength and covered distance during a 6-minute walk test, and a decrease of breathless degree. Researchers conclude that essential amino acids supplementation may be a valid adjunct therapy for patients with advanced COPD, especially for those presenting with loss of muscle mass or respiratory muscle weakness.

NASAL SPRAY IMPROVES RHINITIS-RELATED CHRONIC COUGH
(Wednesday, October 29, 1:00 PM EST)

Patients with rhinitis-related chronic cough may be able to control their cough using nasal sprays. Researchers at Cough Center, Inc, in California treated 266 patients (ages 7 to 85 years) with seasonal allergic (3 percent), nonallergic (65 percent), or mixed rhinitis (32 percent) with open-label combinations of azelastine nasal spray, steroid nasal sprays, ipratropium nasal spray, or cromolyn nasal spray. The median duration of cough was 7 years and the percentage of smokers was less than 1 percent. Of the patients, 72 percent with rhinitis-associated chronic cough experienced improvement with intranasal therapy. The
