Excellent Idea of the Day: Choosing Red Wine Over White - Discovery News

http://news.discovery.com/human/excellent-idea-red-white-wine-121207.html

If given the choice between red and white wines this holiday season, go for red, scientists say. A chemical found in red wine may help prevent cancer and other health problems.

A number of studies over the years have linked this chemical, resveratrol, to health benefits. But perhaps the strongest evidence yet will be presented this week at the conference "Resveratrol 2012," held at the University of Leicester through December 7.

"This is the second conference that brings together all the world experts in resveratrol," Karen Brown, a member of the University's Cancer Biomarkers and Prevention Group, and one of the organizers, was quoted as saying in a press release. We have got a fantastic line up covering cancer, heart disease, diabetes, neurological diseases and life extension."

"Having shown in our lab experiments that (resveratrol) can reduce tumor development, we are now concentrating on identifying the mechanisms of how resveratrol works in human cells," Brown added.

The lab experiments, which she refers to, determined that a daily amount of resveratrol equivalent to two glasses of wine can halve the rate of bowel tumors.

For those wishing or needing to avoid alcohol intake, the compound, found in the skins of red grapes, can be purchased in pill form. Such pills, however, lack the numerous other beneficial vitamins and minerals present in red wine. It's also hard to conduct a convivial holiday toast at the dinner table by clinking pills. Just keep any wine consumption in moderation.

The next step, in terms of research, is to determine the optimum level of resveratrol that humans should ingest.

"It has been shown that high doses of resveratrol may potentially interfere with other medication," Brown explained. "With all the exciting new studies that are being done, especially the clinical trials, I hope we'll have a clearer picture in the next few years."

This week's conference, already underway, includes more than 65 lectures, presentations and posters by different researchers from all over the world.

Excellent Idea of the Day: TB Tracker Halts Disease's Spread - Discovery News

http://news.discovery.com/human/excellent-idea/tb-tracker-infectious-disease-121129.html

Biometric systems are used to track people. A researcher from Microsoft is showing they can also help keep tabs on the spread of tuberculosis, and even stop it.

Partnered with the non-profit project Operation Asha, Bill Thies, who works at Microsoft Research India, developed a way to use a simple fingerprint reader and a netbook to track tuberculosis patients in India.

This may sound big brother-ish, but it's important to make sure TB patients return to local clinics to get their medications. TB is relatively easy to treat and cure, with a standard course of antibiotics. But many patients don't keep taking the drugs because they feel better. "The challenge is to make sure they finish the course of treatment," Thies told Discovery News.

In order to cure a bacterial infection, patients must take enough antimicrobial drugs to kill every last one of the germs. Otherwise, TB sufferers could end up with a drug-resistant strain of the disease.

That outcome is a lot more dangerous to the patient, and worse, it increases the odds that person will infect others.

The fingerprinting system is twofold. First, it identifies the patient. When patient visit local health centers, they place their fingers on a reader, which records the print. The fingerprint reader is connected to a netbook, which also stores the data relevant to that patient.

Second, the netbook uses the local cellular network to send SMS notifications to health-care workers if a patient misses an appointment. When that happens, the health-care worker can go talk to the patient and see what happened.

Thies told Discovery News that the authentication also keeps patients from sending someone else to the local health center in their place.

"Sometimes they will send their wives," he said.

In a neighborhood where poverty is widespread, there is the danger the drugs will be re-sold. They should be taken under supervision in any case, Thies said, because in parts of India many are illiterate. Writing down how to take the proper dose wouldn't help them.

The other big issue is the cost. Thies noted that the fingerprint readers are simple models, as are the computers; the readers are only about $80 each. Both are off the shelf.

So far, Operation Asha has implemented the system across several Indian states. The components are cheap enough that local governments could issue the netbooks and readers for less money than they'd pay for custom-designed hardware. Using the local cell phone network also eliminates the need for high-speed Internet connections.

Operation Asha is looking at applying the same idea to other diseases that require a lot of follow-up, such as HIV, and Thies said there are hospitals in Uganda looking at it as well.

Theis will be giving a presentation on the project at Microsoft's New England Research & Development Center on Dec. 3.
