President Trump gave a speech and signed an executive order on health care Thursday, casting the "Medicare for All" proposals from his Democratic rivals as harmful to seniors.

His speech, which had been billed as a policy discussion, had the tone of a campaign rally. Trump spoke from The Villages, a huge retirement community in Florida outside Orlando, a deep-red part of a key swing state.

In gridlocked Washington, both Democrats and Republicans have signaled there's potential for a deal when it comes to lowering prescription drug prices.

Bridget Desmukes was surprised when Dr. Rita Driggers, Desmukes' OB-GYN in Washington, D.C., recommended low-dose aspirin at her first prenatal appointment this past spring. She knew about daily low-dose aspirin being prescribed to people recovering from a heart attack or stroke. But for pregnant women?

Nearly half a million more children were uninsured in 2018 than in 2017, according to data out Tuesday from the U.S. Census Bureau. The drop stems primarily from a decline in the number of children covered by public programs such programs as Medicaid and the Children's Health Insurance Program.

Plenty of research shows that adverse childhood experiences can lead to depression and other health problems later in life. But researcher Christina Bethell wondered whether positive experiences in childhood could counter that. Her research comes from a personal place.

Peter Grinspoon got addicted to Vicodin in medical school, and still had an opioid addiction five years into practice as a primary care physician.

Then, in February 2005, he got caught.

Lost in all the brouhaha about President Trump's scuttled plan to buy Greenland from Denmark has been this: What do the Greenlandic people think about the whole thing?

In the small capital city of Nuuk, "everybody is talking about it," says Alexander Montgomery-Andersen, a 30-year-old Greenlandic dancer and choreographer. "It's a little comical."

Good news came out from the Centers for Disease Control and Prevention Wednesday: Preliminary data shows reported drug overdoses declined 4.2% in 2018, after rising precipitously for decades.

The Trump administration has announced an ambitious plan to change treatment for kidney disease in the United States.

President Trump signed an executive order Wednesday directing the Department of Health and Human Services to develop policies addressing three goals: reducing the number of patients developing kidney failure, reducing how many Americans get dialysis treatment at dialysis centers and making more kidneys available for transplant.

The federal government's rule designed to support health workers who opt out of providing care that violates their moral or religious beliefs will not go into effect in July as scheduled. The effective date has been delayed by four months, according to court orders.

Louisiana officials announced a deal Wednesday with Asegua Therapeutics, a subsidiary of Gilead Sciences, that would allow the state to provide hepatitis C treatment to its Medicaid and prison populations.

Editor's note: The day after this story published, Mary Washington Healthcare announced it will suspend its practice of suing patients for unpaid bills, stating: "We are committed to a complete re-evaluation of our entire payment process to ensure that all patients know they have access to care."

President Trump signed an executive order Monday on price transparency in health care that aims to lower rising health care costs by showing prices to patients. The idea is that if people can shop around, market forces may drive down costs.

"Hospitals will be required to publish prices that reflect what people pay for services," said President Trump at a White House event. "You will get great pricing. Prices will come down by numbers that you wouldn't believe. The cost of healthcare will go way, way down."

In Florida, Gov. Ron DeSantis signed a bill last week that, if federal authorities give it their go-ahead — still a very big if — would allow his state to import prescription drugs from Canada. That makes Florida the third state to pass such a law, joining Vermont and Colorado. More such legislative attempts are in the works.

Carol Burgos is worried her neighbors think she is bringing the neighborhood down.

She lives in a mobile home park in a woodsy part of Columbia County, N.Y, just off a two-lane highway. The homes have neat yards and American flags. On a spring Saturday, some neighbors are out holding yard sales, with knickknacks spread out on folding tables. Others are out doing yardwork.

Burgos' lawn is unruly and overgrown.

"How bad do I feel when these little old ladies are mowing their lawn and I can't because I'm in so much pain?" she says.

Moral and religious objections to providing health care sometimes arise in medicine: A medical assistant might not agree with blood transfusions. A nurse might not want to assist in sex reassignment surgery.

When the first HIV drug, AZT, came to market in 1987, it cost $10,000 a year.

That price makes Peter Staley laugh today. "It sounds quaint and cheap now, but $10,000 a year at that time was the highest price ever set for any drug in history," he says.

If you've ever had a little one at home with a fever, you might have noticed two options for Tylenol at the store.

There's one for infants and one for children. They contain the same amount of medicine — 160 milligrams of acetaminophen per 5 milliliters of liquid — but the infant version costs three times more.

What gives? It turns out, there's a backstory.
