Like a man on a flying trapeze, K.T. Jones has leapt from one medical study to another during his 15-year struggle with cancer, and he has no doubt that the experimental treatments he has received have saved his life. ... Mr. Jones is one of many patients who have benefited from lifesaving advances in immunotherapy. But he’s an outlier: He is African-American. As money pours into immunotherapy research and promising results multiply, patients getting the new treatments in studies have been overwhelmingly white. Minority participation in most clinical trials is low, often out of proportion with the groups’ numbers in the general population and their cancer rates. Many researchers acknowledge the imbalance, and say they are trying to correct it. (Grady, 12/23)

As the Christmas season kicks into high gear and we're surrounded by gorgeously decorated fir trees and songs of yuletide gay, it's easy to forget that the holidays represent a grim time in terms of health statistics. You're more likely to die of natural causes from Dec. 25 through New Year's Day than at any other time of the year. (Cha, 12/22)

The problems started after Erich Burger returned from an unforgettable safari in Botswana and Zambia last month. ... He headed to a community hospital after about a week of fever and chills, thinking he might have malaria given his recent travel to Africa. ... A sharp-eyed hematology technician discovered when she looked in her microscope that he was suffering from a disease so rare in the United States that it has been seen only 40 times in the past 50 years. The disease is one of the few “universally lethal” infections: It always kills unless it is treated, and it kills quickly. (Sun, 12/22)

Call it the Telltale Brain. The first objective measurement for concussion may have been identified, according to a study published Thursday in the journal Nature, Scientific Reports. By measuring the brain’s electrical reactions to speech sounds, researchers at Northwestern University were able to identify children who had suffered a recent concussion with 90 percent accuracy and those who hadn’t with 95 percent accuracy.

Caroline Brown, a sophomore at the University of Missouri, got a fever over Thanksgiving break. Soon it became painful to bite down, and her cheek began to swell. A trip to her physician confirmed it — Caroline had the mumps. “Mumps kind of sounds like this archaic thing,” Brown said. “We get vaccinated for it; it just sounds like something that nobody gets.  So I just didn’t think that it was possible that I would get it.
