(April 2, 2008 - Insidermedicine) From Quebec City - In a study of nearly 300 patients, potential weight gain was analyzed with respect to sleep habits. Those who slept 5-6 hours per night were 35% more likely to gain 11 or more pounds after 6 years, when compared to those who slept an ideal 7-8 hours per night. Those who slept 9 or more hours were 25% more likely to gain weight.

From Copenhagen - In a review of over 33,000 AIDS patients, those taking the drug Ziagen had a 2 fold higher risk of developing a heart attack. In addition, it was noted that those on Videx had a 50% higher risk. The raised risk was no longer apparent 6 months after the medication was stopped.

And finally, from Cincinnati - Challenging a common belief that the age of donor tissue can impact the survival of a corneal transplant, a new study involving over 1000 patients showed an identical success rate of 86% in those who received a transplant from a donor who was over 65, and those who received one from a younger donor. This finding may lead to a 30% increase in corneas available for transplant.
