| TV doctor dramas violate professional code BALTIMORE (UPI) -- Television medical dramas are filled with breaches of professional conduct and bioethical issues, U.S. researchers found.
Fourth-year medical student Matthew Czarny and faculty from the Johns Hopkins Berman Institute of Bioethics analyzed depictions of bioethical issues and professionalism depicted in the second season of "Grey's Anatomy" and "House, M.D."
The analysis found 179 depictions of bioethical issues ranging from informed consent to organ-transplant eligibility to human experimentation, Czarny said.
Of the 49 incidents of informed consent, 43 percent involved "exemplary" consent discussions, while the remaining instances were described as "inadequate." In general, exemplary depictions portrayed "compassionate, knowledgeable physicians participating in a balanced discussion with a patient about possible treatment options."
Inadequate depictions were "marked by hurried and one-sided discussions, refusal by physicians to answer questions" and "even an entire lack of informed consent for risky procedures," the study found.
The researchers found 22 incidents of "ethically questionable departures from standard practice," most depicting doctors endangering patients unnecessarily in their pursuit of a favorable outcome.
"In almost all of these incidents the implicated physician is not penalized," the study authors said in a statement.

| Racial health gap noted among children DALLAS (UPI) -- There is a major health gap between U.S. minority children and Caucasian children, a review of studies found.
Study author Glenn Flores, a professor of pediatrics at University of Texas Southwestern Medical Center in Dallas, examined racial/ethnic disparities in pediatric care, in studies conducted during a period of more than 50 years.
Flores said the 31.4 million minority children in the United States face higher overall death rates than Caucasians, and some groups face greater violence, higher incidence of HIV/AIDS, sexually transmitted diseases, asthma, attention-deficit hyperactivity disorder and some types of cancers.
Other common disparities for minority children included higher rates of obesity and lower rates of breastfeeding, immunizations, and proper nutrition, Flores said.
"To see those disparities is very disconcerting," Flores said in a statement. "We need to figure out why there are such stark differences when there really shouldn't be in a country that prides itself on equity and justice."

| Diabetes ups post-cancer surgery deaths BALTIMORE (UPI) -- Patients with diabetes who undergo cancer surgery can have a 50 percent increased risk of dying than those who do not have diabetes, U.S. researchers said.
Hsin-Chieh "Jessica" Yeh of the Johns Hopkins University School of Medicine in Baltimore and colleagues say newly diagnosed cancer patients -- particularly those with colorectal or esophageal tumors -- who also have type 2 diabetes have a 50 percent greater risk of death following surgery for cancer.
Yeh and colleagues conducted a systematic review and meta-analysis of 15 previously published studies involving 32,621 patients.
"Diabetic patients, their oncologists and their surgeons should be aware of the increased risk when they have cancer surgery," Yeh says in a statement. "Care of diabetes before, during and after surgery is very important. It should be part of the preoperative discussion."
However, the researchers say their review could not answer the question of why cancer patients with type 2 diabetes are at greater risk of death after surgery.
The findings are scheduled to be published in the April issue of the journal Diabetes Care.

| Flaxseed can lower cholesterol in men AMES, Iowa (UPI) -- Eating about three tablespoons of flaxseed for three months decreased cholesterol in men, but not women, by about 10 percent, U.S. researcher say.
Study leader Suzanne Hendrich, a professor in food science and human nutrition at Iowa State University's Nutrition and Wellness Research Center, examined the effects of flaxseed lignan in 90 people diagnosed with high cholesterol.
Hendrich says the expected outcome from cholesterol-lowering drugs is approximately 10 percent to 20 percent, but the flaxseed outcome is still a reasonable more natural outcome for some men.
"Because there are people who can't take something like Lipitor, this could at least give you some of that cholesterol-lowering benefit," Hendrich says in a statement.
"The other thing is, there are certainly some people who would prefer to not use a drug, but rather use foods to try to maintain their health. So this potentially would be something to consider."
Hendrich, graduate student Kai Ling Kong and doctoral graduates Zhong Ye, Xianai Wu and Sun-Ok Lee are scheduled to present the results at the American Society for Nutrition's annual meeting at Experimental Biology, April 24-28, in Anaheim, Calif.
