Health Watch: Eliminating ozone-damaging inhalers
FDA requires switch from CFC-propelled inhalers
Old-fashioned inhalers that use chemicals harmful to the ozone layer are being phased out for a more environmentally friendly medicine for asthmatics.
Chlorofluorocarbon-propelled inhalers will not be available in the United States after Dec. 31, 2008, because they contribute to the depletion of the ozone layer.
The U.S. Food and Drug Administration is requiring asthmatics switch to hydrofluoroalkane-propelled albuterol inhalers, or HFA-propelled inhalers.
Albuterol inhalers are used to treat wheezing in patients with asthma and chronic obstructive pulmonary disease, which includes chronic bronchitis and emphysema.
LASIK goes galactic with NASA
LASIK surgery, used to correct nearsightedness, farsightedness and astigmatism, has been cleared by NASA as an appropriate treatment for aspiring astronauts.
NASA was reluctant to go forward with refractive surgery due to concerns about the stability of the LASIK flap and the resulting quality-of-vision after the procedure.
LASIK involves making a surgical incision to create a flap on the surface of the clear outer part of the eye called the cornea. The flap is then folded back to allow a laser to correct the patient's vision and laid back into place, where it re-adheres to the cornea.
After conducting studies under extreme conditions and assessing the advances of the technology involved, NASA decided to take another look and found advanced LASIK ready for astronauts. (ARA)

A poll finds that 62 percent of Americans believe wounded Iraq war veterans do not receive high-quality care in military and Veterans Administration hospitals once they return to the United States. The survey by the Harvard Opinion Research Program at the Harvard School of Public Health and Harris Interactive is part of an ongoing poll series, Debating Health: Election 2008.
New research at the University of Calgary shows that thermal stress can lead to an increased risk of sudden infant death syndrome.
Increased temperature such as over-wrapping a baby at nighttime or increasing the room temperature can affect the baby's pattern of breathing.
Other known contributing factors to SIDS include babies sleeping in a belly-down position and exposure to cigarette smoke. Combining any of these factors with thermal stress may put babies at greater risk.
In a new study, Harvard School of Public Health researchers found evidence that elderly people in the U.S. who have an active social life may have a slower rate of memory decline. Memory loss is a strong risk factor for dementia, a syndrome estimated to affect up to 10 percent of the U.S. population 65 years and older.
The results of the study showed that individuals with the highest social integration had the slowest rate of memory decline. In addition, memory decline among the most integrated was less than half the rate among the least integrated. These findings were independent of factors such as age, gender, race and health status.
