More than a third of all American adults have gone online to find a diagnosis, according to a 2013 Pew survey, and half of those people wound up discussing what they found with their health care provider. Looking for a digital diagnosis can either increase or alleviate concerns about a possible illness, according to Microsoft researchers. And there’s even a word that’s cropped up — “cyberchondria” — to describe what happens when searching for medical information starts to become a condition unto itself.

The divide between health outcomes for the richest and poorest Americans is among the largest in the world, according to a new study. Of people in households making less than $22,500 a year, 38 percent reported being in poor or fair health in a survey taken between 2011 and 2013. That's more than three times the rate of health troubles than faced by individuals in households making more than $47,700 a year, where only 12 percent of people reported being in poor to fair health, according to the findings published in Health Affairs.

Heart disease is the leading cause of death for people with Type 2 diabetes. Surely, then, the way to dodge this bullet is to treat the disease and lower blood sugar. Well, maybe. Growing evidence suggests that the method by which blood sugar is lowered may make a big difference in heart risk. That has raised a medical dilemma affecting tens of millions of people with Type 2 diabetes — and for the doctors who treat them. (Kolata, 6/5)

Treatments for the [arthritis] afflicting about 1.5 million Americans can have terrifying side effects, so doctors and patients were excited when Actemra reached the U.S. market in 2010. Unlike competing drugs, it wasn’t associated with heart attacks, heart failure, or life-threatening lung complications. Yet hundreds of patients taking Actemra have died from such problems, and many more have suffered harm. STAT analyzed more than 500,000 side-effect reports on rheumatoid arthritis drugs, and found clear evidence that the risks of heart attacks, strokes, heart failure, and other conditions were as high or higher for Actemra patients than for patients taking some competing drugs.

Scientists are paying increasing attention to the “indoor microbiome,” the billions of bacteria, viruses and fungi that we share our homes and offices with. But not all those micro-organisms are bad for us, experts note. And exposure to a rich array of indoor germs may actually be salutary, helping stave off a variety of illnesses. (Schiffman, 6/6)

Women with metastatic breast cancer are living longer. In 1990, there were 105,354 women alive with the disease in the United States, according to a new analysis. Now that figure has risen to an estimated 154,794. (Bakalar, 6/5)

A major outbreak of botulism, a rare type of food poisoning, struck 10 people in Northern California over the last month, killing one Antioch man. Sacramento County health officials traced the illness to a gas station in Walnut Grove, where the victims were sickened after eating nacho cheese sauce from a dispenser. Botulism is caused by a dangerous nerve toxin created when a bacteria called clostridium botulinum multiplies in food. Symptoms begin with vomiting and blurred vision followed by a slow paralysis that can lead to respiratory failure if an antitoxin is not administered in time. (Caiola, 6/5)

A 31-year-old man who died earlier this year contracted flesh-eating bacteria while swimming in the Gulf of Mexico with a freshly inked tattoo, according to a new report. The gruesome details of the man's death are documented in a BMJ case report published May 27, 2017, which chronicles how the bacteria slowly ate away the flesh on the man's leg in the weeks preceding his death.
