Student uses the "environment of disease" to predict the next outbreak
December 5, 2007 11:01 AM - Paul Schaefer, ENN
Manhatten, KS - - It was one of those things you hear about on the news: an outbreak of monkeypox in the Chicago area. An animal dealer placed infected rats from Africa next to a crate of prairie dogs. The disease spread to the prairie dogs, which were then sold in pet stores across the nation. Dozens of people in multiple states were sickened from contact with the animals.
The incident gave a Kansas State veterinary medicine graduate student, Christine Ellis a little bit of global perspective. At the time, she was working as an associate veterinarian at The Midwest Bird and Exotic Animal Hospital in the Chicago area.

Study: Price of lower-calorie foods rising drastically
December 4, 2007 02:52 PM - University of Washington Newswire
Seattle - As food prices rise, the costs of lower-calorie foods are rising the fastest, according to a University of Washington study appearing in the December issue of the Journal of the American Dietetic Association. As the prices of fresh fruit and vegetables and other low-calorie foods have jumped nearly 20 percent in the past two years, the UW researchers say, a nutritious diet may be moving out of the reach of some American consumers.
Losing virginity early or late tied to health risks
December 4, 2007 02:43 PM - Reuters
NEW YORK (Reuters Health) - People who start having sex at a younger or older than average age appear to be at greater risk of developing sexual health problems later in life, a new study suggests.
The findings, according to researchers, cast some doubts on the benefits of abstinence-only sexual education that has been introduced in U.S. public schools.
Using data from a 1996 cross-sectional survey of more than 8,000 U.S. adults, the researchers found that those who started having sex at a relatively young age were more likely to have certain risk factors for sexually transmitted diseases (STD) -- including a high number of sexual partners and a history of having sex under the influence of alcohol.

NEW DELHI - Human trials of a US-produced HIV/AIDS vaccine were halted in India last month (November) after it was found to induce poor immune responses.
The vaccine, developed by the US-based Targeted Genetics Corporation, uses the adeno-associated virus (AAV) as a vector to deliver an AIDS vaccine against subtype C, the dominant HIV subtype in India.
India's National AIDS Research Institute (NARI) tested the vaccine on 30 volunteers.
Calcium level may signal risk of mental decline
December 4, 2007 11:18 AM - Reuters
NEW YORK (Reuters Health) - In elderly people, higher levels of calcium in the blood are associated with poorer mental function and faster decline in cognitive ability, Dutch researchers have shown.
Some diseases that increase blood calcium -- such as kidney failure, cancer and excessive parathyroid gland activity -- could be a factor in the relationship, although it's also possible that an individual's calcium "set point" plays a role in cognitive decline with age, note Dr. Miranda D. Schram and colleagues in the Journal of the American Geriatrics Society.

WASHINGTON (Reuters) - People with a disorder in which they are convinced they are ugly have a brain glitch when processing things they see, researchers said on Monday.

Honey eases nighttime cough
December 3, 2007 05:52 PM - By Anne Harding, Reuters
NEW YORK (Reuters Health) - A spoonful of honey can quiet children's nighttime cough and help them -- and their parents -- sleep better, a new study shows.
When compared to the cough syrup ingredient dextromethorphan or no treatment, honey came out on top.
"The results were so strong that we were able to say clearly that honey was better than no treatment and dextromethorphan was not," Dr. Ian M. Paul of Pennsylvania State University in Hershey, one of the study's authors, told Reuters Health.
