Experience Counts

1 Some Docs Better Than Others at Detecting Cancer

Radiologists who read a high volume of mammograms are better at determining which suspicious lesions are benign, says a new study. “... radiologists with higher interpretive volume had significantly lower false-positive rates and recalled fewer women per cancer detected,” said investigator Diana S.M. Buist, Ph.D., M.P.H. A false positive is when further testing for a suspicious lesion is required but no cancer is found. They account for $1.6 billion annually in additional tests and untold anxiety for patients. Currently, the minimum interpretive volume required of US radiologists is 960 mammos every two years. Researchers estimate that increasing that to 1,000 would result in 43,629 fewer women being recalled and significant savings from not having to do further tests.

Duerson Shot Himself in Chest

2 Former Player Wants NFL to Research His Brain

Former Chicago Bears safety Dave Duerson was found dead last Thursday of self-inflicted gunshot wound to the chest, and he wanted his brain to be given to the NFL brain bank to be examined for chronic traumatic encephalopathy, CTE. The debilitating brain injury known as CTE is believed to affect football players who've had serious blows to their heads, but the only way to determine if a person has the injury is by brain examination after death. It could take months for researchers to determine if Duerson did actually have CTE, which may cause bizarre behavior, severe depression and memory problems. CNN reports that former NFL players, like Fred McNeil and George Visger, have suffered severe memory problems after their years of playing football.

Orangutans, Tigers at Risk

3 Girl Scouts Say No to Selling Cookies to Save Apes

Michigan Girl Scout members Rhiannon Tomtishen and Madison Vorva are refusing to sell Girl Scout cookies after learning that they contain palm oil, the biggest culprit behind endangered wildlife losing their forest homes in Southeast Asia. Orangutans, pygmy elephants, and Sumatran tigers are all at risk from palm oil plantations. Grist reports that the protesting scouts are trying to call attention to the problem, but Girl Scouts USA CEO Kathy Clonginer has refused to take action. Girl Scouts across the country have also tried to reason with the organization. The Girl Guides in Britain have eliminated palm oil from their cookies, resulting in a 60 to 70 percent reduction in saturated fat. It seems that olive oil and canola oil are ape-friendly, while the fatty palm oil is not.

Are Coca-Cola and Pepsi Guilty?

4 Caramel Color in Soft Drinks May Cause Cancer

The Center for Science in the Public Interest (CSPI) believes that the caramel color used in Coca-Cola and Pepsi could cause cancer, reports ABC News. Yet, the soft drink industry denies that caramel color is harmful. CSPI is requesting that the FDA ban certain types of caramel color in soft drinks and other foods. They say that their request is based on research completed years ago by the National Toxicology program, which found that a contaminant in caramel coloring caused cancer in mice and possibly rats. CSPI explains that caramel color isn't as innocent as it sounds. While pure caramel is made by heating sugar, the caramel color used in Pepsi and Coca-Cola is produced by reacting sugars with ammonia. CSPI says that the chemicals created by the reaction are proven carcinogens.

Glucose Consumption Increased

5 Cellphone Use Changes Brain Activity

The weak radio-frequency signals of cellphones, long touted as safe, have been shown to have the potential to alter brain activity. It's not known if the changes have a "meaningful effect on a person's overall health," cautions Dr. Nora D. Volkow, director of the National Institute on Drug Abuse. The study, conducted by the National Institutes of Health, found that less than one hour of cellphone use speeds up brain activity in the area closest to the phone antenna, reports New York Times. Researchers placed one active and one non-active phone at each ear of 47 participants during brain scans. The scans showed "increased consumption of glucose" in areas of the brain near the activated cellphone. The findings were published in The Journal of the American Medical Association.

Toast to the Heart

6 Moderate Alcohol Protects Against Heart Disease

Enjoying one drink a day or less of any alcoholic beverage may offer protection against heart disease. Researchers from the University of Calgary report that people who drink alcohol in moderation are up to 25 percent less likely to develop heart disease compared with people who don't drink alcohol at all. The study revealed that the heart-healthy benefits of alcohol stem from the alcohol content of the beverages, not the type of drink (beer, wine or spirits). Alcohol may protect the heart by increasing levels of good cholesterol circulating in the body. The research findings are published in BMJ.

Animals Treated Humanely

7 Researchers Say Animal Testing Saves Human Lives

At the annual meeting of the American Association for the Advancement of Science (AAAS), researchers who are or have been involved in animal research defined animal testing telling a small group that not doing it would be unethical and cost human lives. Stuart Zola of Emory University notes that treatments for diseases such as diabetes and polio were made possible through animal research and animals are currently being used in hepatitis, HIV and stem-cell related research. The researchers also stress that animal research in the US is regulated and that animals are treated humanely. Institutions that receive federal funding, for example, must have animal care and use committees that review all protocols even if only a single animal is use.

Makes Erection Difficult

8 Marijuana Worsens Male Sexual Dysfunction

Marijuana is the most widely-used illicit drug globally and past research has found that it negatively affects certain receptors in the brain. Now researchers have found that those same receptors are also found in the penis, and that cannabis, the active ingredient in marijuana, antagonizes those receptors making it more difficult for a man to achieve and maintain an erection. Dr. Rany Shamloul, a postdoctoral fellow at Queens University says that the findings will change the current understanding of the magnitude of cannabis use on sexual health, as past studies have found conflicting results. He encourages renewed use of research resources to study the effects marijuana has on male sexual function. Dr. Shamloul’s research is published in the Journal of Sexual Medicine.

Women's Heart Health Month

9 Gender Does Not Increase Risk of Heart Attack

Cardiovascular disease kills nearly twice as many women in the United States than all types of cancer, according to the American Heart Association, but simply being a woman does not increase the risk of dying from a heart attack. A study from the University of Michigan Cardiovascular Center found that although overall women had higher in-hospital heart attack deaths, the difference was related to age and additional health problems, not gender. Women account for about one-third of patients who undergo cardiac procedures such as angioplasty, but they tend to be older and have more co-morbidities in addition to primary disease. Women are also more likely to have vascular complications or a bleeding episode in the hospital that requires a transfusion.

Brain Waves Detect Risk

10 Autism May Be Seen in Brain's Electrical Activity

The electrical activity of the brains of 79 six to 24 month old infants watching people blow bubbles showed that electroencephalograms (EEG) may predict who is at a high risk of developing autism. With EEG, brain waves were recorded and analyzed with computer algorithms that detected patterns that were not obvious to the researchers. Over half of the infants had an older sibling with autism and previous research indicates that kids with older siblings are more likely to develop it or will have some of the symptoms. Overall, the test had an 80 percent accuracy rate with 100 percent in predicting risk in boys compared to only 60 percent in girls. If further research proves EEG is a reliable tool, very early detection will result in very early intervention which is known to be beneficial.
