An estimated 32 million children in the United States live in homes with firearms, nearly 7 million of whom have at least one firearm in the household that's unlocked and loaded. That's according to a new study published in JAMA Network Open. "This study sheds further light on the fact that there are millions of kids living in this country, in households where weapons are readily available and often not locked up," says Dr. Chethan Sathya, a pediatric surgeon and director of the Center for Gun Violence Prevention at Northwell Health, a health system in New York. "Many of these families don't know the risk of having that gun not being locked up." (Chatterjee, 5/12)

Death by suicide is a male emergency. Although three times as many women as men report suicidal ideation and attempts, the vast majority of deaths by suicide in the U.S. — up to 80% — are among men. The reasons: higher impulsivity, lower reported fear of death, and, crucially, easy access to guns. (Merelli, 5/12)

Candidemia incidence and associated 30-day mortality have risen in the United States since 2015, according to a study published yesterday in Clinical Infectious Diseases. For the study, a team led by researchers with Houston Methodist Hospital examined data from a nationwide database of electronic health records to analyze trends in candidemia incidence from 2015 through 2014. Candidemia is a severe and life-threatening bloodstream infection caused by species of Candida yeast. Most often found in medically vulnerable and chronically ill patients, Candida species cause an estimated 23,000 bloodstream infections every year in the United States, with mortality rates ranging from 25% to 40%.

The United States is hardly the only country where heavy and binge drinking is a problem. But Americans face a unique crisis: This country’s obesity and diabetes epidemics, combined with heavy alcohol use, are causing more people to get sick from a liver disease that, until recently, didn’t even have a name.

As millions of people lose weight on powerful new obesity drugs, most are asking: what comes next? New findings show they have options to combat the dreaded yo-yo effect, including a surprising potential benefit from a humble gut bacteria supplement. A pair of Eli Lilly & Co. studies released Wednesday showed that while medicine is the best way to keep weight steady, some patients might be able to reduce their dose or switch to a pill. And a small, provocative trial found that a bacteria called Akkermansia muciniphila helped people who’d slimmed down just by dieting keep some weight off. (Kresge, 5/12)

In January, Health Secretary Robert F. Kennedy Jr. joined Katie Miller, the wife of Stephen Miller, the White House deputy chief of staff for policy, on her podcast. He was there to celebrate his MAHA victories, but he soon veered into the singular, seemingly indestructible biology of President Donald J. Trump. “He has the constitution of a deity,” Kennedy marveled. And the key to the president’s inexplicable vigor, Kennedy suggested, could be found in his hormones. (Ghorayshi, 5/12)
