19-08 Segment 1: Veterinarian Suicide

RHJ 19-08a wordpress

A new CDC report shows that suicide among veterinarians is much higher than in the general population. Experts discuss the unique stresses that affect these professionals, including financial, compassion fatigue, euthanasia, and online harassment. They also discuss measures being taken to prevent mental health struggles and suicide.

Guests:

  • Dr. Jason Sweitzer, veterinarian, Thousand Oaks, CA and board member, Not One More Vet

19-08 Segment 2: Research Ethics: How Far Have We Come?

RHJ 19-08b wordpress

In the mid-1960s, many Ivy League and Seven Sister colleges as well as prestigious prep schools allowed researchers to photograph incoming students naked as part of work on a now-discredited theory linking physical characteristics to leadership potential. A former student who went through it, now a physician and writer, discusses how research ethics have changed in the last 50 years.

Medical Notes this week…

Explorers and scientists have been looking for the fountain of youth for thousands of years. Now there’s speculation they may have found an aging inhibitor in a generic HIV drug called Lamivudine. A study in the journal Nature shows that mice who are equivalent to 75 years old in human terms experienced dramatically reduced inflammation and other signs of aging when they received the drug. Lamivudine was approved for treating HIV in 1995. Scientists say they’re anxious to start human anti-aging trials.

Speed limits on highways are usually set as a result of engineering studies. But some local governments override those recommendations, believing that the lower the limit is, the safer the road will be. A new study in the journal Accident Analysis and Prevention shows that’s only partially true. Crashes are reduced when a speed limit is set five miles per hour lower than recommendations… but setting the speed limit 10, 15, or 25 miles per hour lower actually increases both total crashes and fatal crashes because so many drivers completely ignore the limit.

And finally… educators have long sought ways to get girls more interested in science. Now a study in the journal Psychological Science has some tips. The study shows that suggesting “let’s do science” is much more effective at getting girls engaged than suggesting “let’s be scientists.” Researchers say pervasive stereotypes, even among the young, torpedo the idea that very many girls ever do become scientists.

19-07 Segment 1: When Law Enforcement and Trauma Care Collide

RHJ 19-07a wordpress

Many patients arrive in the emergency room as a result of violence or car crashes—events in which police have an investigative interest. Sometimes, police needs clash with trauma care, and priorities are hashed out case by case. Experts discuss which priorities come first and when, and the procedures needed to smooth out sometimes contentious interaction.

19-07 Segment 2: When Does Genetic Engineering Go Too Far?

RHJ 19-07b wordpress

Advancements in genetic science are often clouded in ethical controversy. Often, scientists are accused of “playing God.” Experts discuss a new platform where scientists and public can debate it, and from which education can be disseminated.

Medical Notes this week…

A cancer diagnosis can create stress that goes beyond the breaking point. A new study in the journal Nature Communications shows that people with cancer are more than four times more likely to commit suicide compared to other people. White men and people who receive a diagnosis at a younger age are most likely to complete suicide, along with people who are diagnosed with lung, head and neck, and testicular cancers. Researchers say that even though cancer is a major cause of death in the U.S., most cancer patients survive it and die of other causes.

Electric scooters are a rapidly rising cause of injury, and a new study shows that one in three people involved in an e-scooter accident is injured badly enough to need treatment in the E.R. The study in the journal JAMA Network Open shows that 40 percent of those hurt had head injuries and another 32 percent had fractures. Only four percent of those hurt were wearing a helmet at the time of the crash. Falls rather than collisions made up nearly three-quarters of the accidents.

And finally… it turns out that people who are good navigators are almost always good at identifying smells as well. A study in the journal Nature Communications finds that the same area of the brain is used for both of these two very different tasks, and that the brain region is bigger in people who are good at them. Scientists admit the finding surprised them.

19-06 Segment 1: Xenotransplantation—Organ From Other Species

RHJ 19-06a wordpress

After attempts to use non-human primates as a source of scarce organs for transplant, doctors have turned to pigs for a variety of reasons. They’re now making great progress against the largest hurdle—rejection. One of the world’s foremost xenotransplantation experts discusses how the process might work and what the future might look like for millions of potential organ and tissue recipients.
