STATIN THERAPY MAY BENEFIT ICU PATIENTS
(Tuesday, October 28, 1:00 PM EST)
Statins may provide a protective effect for patients admitted to the ICU. In a retrospective study, researchers from Saudi Arabia compared 194 ICU patients who received consistent statin therapy for 1 year prior to ICU admission with a control group of 1,188 patients who did not receive statin therapy. The ICU mortality rate for the statin group was 10 percent compared with 12 percent for the control group. The apparent mortality benefit persisted after controlling for differences in age and gender. Researchers speculate that their study demonstrates a potential survival benefit for ICU patients receiving statin therapy.

ANKLE EXERCISES INCREASE BLOOD FLOW DURING AIR TRAVEL
(Tuesday, October 28, 1:00 PM EST)
Simple ankle exercises, done while sitting or at rest, may help increase blood flow through the legs. In a study conducted at St. Joseph Mercy Oakland in Michigan, 18 healthy volunteers, aged 20 to 40 years, underwent Doppler measurements of right and left femoral vein blood velocity while supine, at rest. They also underwent Doppler measurements of right femoral blood velocity while sitting and during ankle exercise. Volunteers flexed their ankles 80 times per minute and rested for at least 3 minutes before each measurement. At rest, while supine, average blood velocity was the same in the right and left femoral vein (17 cm/s). During exercise, while supine, average blood velocity increased to 30 cm/s. When sitting at rest, femoral blood velocity decreased from 17 cm/s to 9 cm/s but increased to 18 cm/s with exercise. Researchers suggest that ankle exercise may reduce stasis in bedridden patients, an
