Los Angeles Times – Let's limit our intake of corn-syrup ads (Sept. 30, 2009)
A nationwide marketing campaign says high-fructose corn syrup has been unjustly blamed as a cause of obesity. True? Yes and no. Nutrition experts say there may indeed be little if any difference between high-fructose corn syrup and sugar. But the experts say your body doesn't always know what's good for it. Dr. Elizabeth Parks, an associate professor of clinical nutrition at UT Southwestern, comments. Read More

Science Daily – Certain cancers more common among HIV patients than non-HIV patients (Sept. 28, 2009)
Researchers at UT Southwestern have found that non-AIDS-defining malignancies such as anal and lung cancer have become more prevalent among HIV-infected patients than non-HIV patients since the introduction of anti-retroviral therapies in the mid-1990s. "It's a genuine increase in the incidence of these cancers," said Dr. Roger Bedimo, assistant professor of internal medicine at UT Southwestern and lead author of a study in the October edition of the Journal of Acquired Immune Deficiency Syndromes.

Lubbock Avalanche-Journal – Breast cancer survivor shares hopes with other victims (Sept. 23, 2009)
When Jennifer Riley slips on her sneakers for October's Susan G. Komen Race for the Cure, she won't just be raising money for breast cancer research and education. The survivor for almost a decade will be showing those battling the disease they are not alone in their fight. Even better, she'll be showing them she won. Riley underwent radiation therapy and a lumpectomy to remove the tumor at UT Southwestern. The yearlong research therapy was designed to preserve the then-29-year-old's fertility. Read More

KERA (PBS) Think – Is there a coming crisis in the field of geriatric medicine? (Sept. 18, 2009)
We'll talk with UT Southwestern's Dr. Craig Rubin, chief of geriatrics, and geriatrician Dr. Amit Shah. "Patients are seeing other physicians," Dr. Shah says. "They might be seeing an orthopedic surgeon, they might be seeing a cardiologist or a rheumatologist. All these doctors also need additional training, because it's rare for an older person to have just one doctor. They need both a geriatrician and they need physicians with additional training in geriatrics in addition to their specialty." Watch Video

Wall Street Journal – The Nobel Prize Will Go To... (Sept. 18, 2009)
Next month, Nobel Prizes once again will be handed out to scientists who have conducted field-changing research.

Dr. Jerry Shay, a professor of cell biology at
UT Southwestern, comments. Read More

CBS The Morning Show – Double-whammy from fatty foods (Sept. 16, 2009)
Once you get started eating ice cream, do you feel like you could eat the whole carton? Or maybe polish off that second deluxe cheeseburger? On "The Early Show," CBS News Medical Correspondent Dr. Jennifer Ashton reported on new research by UT Southwestern that suggests the answer may lie in certain saturated fats that, in essence, trick the brain into eating more.

Cardiology Today – Far from obsolete, physical exams, patient history important
for GF diagnosis (Sept. 16, 2009)
Using information from patient history and a clinical physical examination is an inexpensive and low-risk way of gathering important diagnostic and prognostic information for patients with HF. Dr. Mark Drazner of UT Southwestern comments. Read More

Discover Magazine – Researchers discover how ice cream controls your brain (Sept. 15, 2009)
So your date this weekend didn't turn out like you'd hoped. A pint of Ben and Jerry's sounds like the perfect remedy, right? But while a bowl of Phish Food might make you feel good now, if a recent study is any indication, the ice cream binge may trick your brain into scarfing high-fat foods for the next several days. Findings from a new UT Southwestern study suggest that fat from certain foods we eat makes its way to the brain. Once there, the fat molecules cause the brain to send messages to the body's cells, warning them to ignore the appetite-suppressing signals from leptin and insulin, hormones involved in weight regulation.

NBC TODAY SHOW – Doctor analyzes 'Girl Who Cries Blood' (Sept. 11, 2009)
Twinkle is a 14-year-old girl who suffers from a mysterious condition that makes her spontaneously bleed from her eyes, hands and head. Her story is being told in a new special that will air this weekend on the National Geographic Channel. Dr. George Buchanan is a pediatrician at UT Southwestern who met Twinkle in India as part of the National Geographic team. The Today Show's Al Roker interviewed Dr. Buchanan live in the show's New York studio. Watch Video

KXAS-TV CH 5 (NBC) Dallas/Fort Worth – Doc questions girl's spontaneous bleeding (Sept. 11, 2009)
A Dallas doctor who went to India for a documentary on a girl who cries blood says he suspects the bleeding is not a medical condition. Dr. George Buchanan is considered one of the best at treating pediatric blood disorders. He heads the program at Children's Medical Center Dallas and teaches future pediatricians at UT Southwestern. National Geographic Channel asked Dr. Buchanan to go with its team to Mumbai to be part of a documentary about Twinkle, a 14-year-old girl who claims to cry blood. Watch Video

Science Magazine – Career advice: Audacity, part 1 (Sept. 11, 2009)
Some scientists are driven to ask big, bold questions. They are committed to following the path to the answers even though it may lead to rejection, ridicule, personal attacks, lost funding, or other trials. Everyone has a style of their own, says Steven McKnight, a biochemist at UT Southwestern, and incremental and risky styles of science are equally valid. Read More

KXAS-TV CH 5 (NBC) Dallas/Fort Worth – Docs hope a protein is key to melanoma vaccine (Sept. 10, 2009)
Dr. James Huth at UT Southwestern is heading up a study to develop a vaccine for melanoma patients. "We have seen cases where melanoma goes away due to a reaction in the immune system," Dr. Huth says. Watch Video

United Press International – Uncluttered home helps Alzheimer's patient (Sept. 10, 2009)
An uncluttered and organized home can keep people with Alzheimer's disease from feeling overwhelmed and help them function better, a U.S. expert suggests.

Medical News Today – Even in a safety net health system, colorectal cancer screening disparities remain (Sept. 8, 2009)
The nationwide rate of colorectal cancer screening is 61 percent, with much of the lack of screening concentrated among blacks, Hispanics and those without insurance. A new study shows that the screening rate was merely 22 percent among individuals served by a safety net health system in Texas. Dr. Samir Gupta, M.D., assistant professor of internal medicine at UT Southwestern, comments. Read More

Science News – Mice with mutation feel the burn (Sept. 4, 2009)
A gene that helps regulate inflammation also stops fat cells from wasting energy. When the gene, called I kappa B kinase epsilon or IKKε, is missing, mice turn a high-fat diet into heat instead of body fat, a new study in the Sept. 4 Cell shows. The researchers think that IKKε works mainly in fat and the liver, but since this study removed the gene from every cell in the body, the team cannot be sure where the gene exerts its influence most strongly, says Philipp Scherer, director of the Touchstone Diabetes Center at
UT Southwestern. Read More

Reuters – Texas doctors bust myths about insulin (Sept. 2, 2009)

People newly diagnosed with type 2 diabetes often resist taking insulin because they fear gaining weight, developing low blood sugar, and seeing their quality of life decline. Doctors also may be reluctant to start insulin right off the bat. But a new study suggests that those fears are largely unfounded. Dr. Ildiko Lingvay comments. Read More
