AUDIE CORNISH, HOST:

Aaron Reid is lying in a hospital bed at the National Institutes of Health Clinical Center when doctors arrive to make sure he's ready for his experimental treatment.

"How's your night? Any issues?" asks Dr. Katherine Barnett, a pediatric oncologist, as they begin to examine Reid.

Reid, 20, of Lucedale, Miss., has been fighting leukemia since he was 9 years old. He has been through chemotherapy and radiation twice, a bone marrow transplant and two other treatments.

Since Zika emerged as a threat to babies, it has been a mystery exactly how much of a danger the mosquito-borne virus poses to children.

But now, the largest study to follow kids who were exposed to the virus in the womb is providing more answers.

The study involved 1,450 babies who had been exposed to the virus, and who were 1-year-old by February 2018. Six percent were born with birth defects, and 14 percent developed problems that could be blamed on the virus by the time they turned 1, the study found.

Rita Adele Steyn's mother had a double mastectomy in her 40s because she had so many lumps in her breasts. Her first cousin died of breast cancer. And Steyn's sister is going through chemotherapy for the disease now. Steyn worries she might be next.

"Sometimes you feel like you beat the odds. And sometimes you feel like the odds are against you," said Steyn, 42, who lives in Tampa, Fla. "And right now I feel like the odds are against me."

On the third floor of a big Soviet-era apartment building in Kharkiv, Ukraine, the mother of one of the world's first babies created with DNA from three different people cracks open her door.

"Hello; my name is Tamara," she whispers, to avoid waking her son from his nap.

In a clinic on a side street in Kiev, the capital of Ukraine, doctors are doing something that, as far as is publicly known, is being done nowhere else in the world: using DNA from three different people to create babies for women who are infertile.

Doctors at the National Institutes of Health say they've apparently completely eradicated cancer from a patient who had untreatable, advanced breast cancer.

The case is raising hopes about a new way to harness the immune system to fight some of the most common cancers. The methods and the patient's experience are described Monday in a paper published in the journal Nature Medicine.

Gene therapy is showing promise for treating one of the most common genetic disorders.

Results of a study published Wednesday show that 15 of 22 patients with beta-thalassemia who got gene therapy were able to stop or sharply reduce the regular blood transfusions they had needed to alleviate their life-threatening anemia. There were no serious side effects.

There's more bad news about the nation's devastating opioid epidemic.

In just one year, overdoses from opioids jumped by about 30 percent, according to a report released Tuesday by the Centers for Disease Control and Prevention.

Hopes were dashed this week that the United States was finally making progress in the fight against childhood obesity.

Contrary to previous reports, the epidemic of fat has not abated. In fact, there's been a big jump in obesity among the nation's youngest children, according to the latest analysis of federal data, published Monday in the journal Pediatrics.
