Medical Notes this week…

Patients with asthma who haven’t responded well to treatment may be greatly helped  by injections of a drug for eczema. Two studies in the New England Journal of Medicine show that patients with moderate to severe asthma reduced flare-ups by half or more after getting an injection of dupilumab,, a drug approved by the FDA for eczema in 2017. Patients taking the drug cut their emergency room visits about in half and those taking steroids for asthma were also able to reduce their dose.

Scientists have developed a prototype early warning system for the four most common types of cancer that makes a dark mole appear on the skin when it’s activated. Researchers call it a “biomedical tattoo” and say it would be inserted under the skin, monitoring genetic changes in the body. Mutations associated with lung, colon, breast or prostate cancer would make the implant turn a dark color, which would be visible through the skin. researchers say in the journal Science Translational Medicine that the test is at least 10 years away.

Surviving a heart attack may be as simple as exercise. A study in the European Journal of Preventive Cardiology tracked nearly 15,000 people for 40 years. It found that more than 10 percent of them eventually had a heart attack but those who had pursued a light exercise regimen were 32 percent less likely to die from it compared to people who had been sedentary. Those exercising at least moderately were nearly 50 percent less likely to die.  

And finally, researchers say walking and chewing gum at the same time amounts to good exercise. A study in the Journal of Physical Therapy Science shows that chewing gum while you walk raises heart rate over walking alone, and makes people walk faster and farther. For men over 40, that adds up to a significant additional calorie burn while for women it didn’t make as much difference.

And that’s Medical Notes this week.
