Violence weighs heavy on a child's mind

By Stephanie Smith
CNN Medical Producer

Being around violence is stressful, no doubt, but  it turns out that exposure to homicide may be causing cognitive problems in children, according to a new study.   What is striking: Children who are not directly witnessing the violence, but who live near it, may also be affected.

"Local violence weighs on the minds of children...," according to the study, published today in the Proceedings of the National Academy of Sciences. "The pattern of findings is consistent with the literature on acute stress disorder, which is defined as a response to a threatening event that induces fear, helplessness, or horror."

FDA warns companies selling at-home genetic tests

By Carrie Gann
CNN Medical News Intern

The FDA is warning companies that sell laboratory-to-consumer genetic testing that their products cannot be marketed without FDA approval. The agency said that it is concerned about the accuracy of the tests and that consumers may use the results to make important medical decisions.

On Friday, the FDA sent letters to five companies - 23andMe, Navigenics, DeCODE Genetics, Illumina and Knome – notifying them that they must submit their products for review or discuss with officials why their products do not require FDA approval. In its letter to 23andMe, the agency said it wants to prevent consumers from being “misled by incorrect test results or unsupported clinical interpretations.”

Kevorkian: 'I have no regrets'

"He shifted his gaze from his lawyer back to me. 'Sanjay, you want to know the single worst moment of my life?'

That wasn't the question I asked, but in fact I was curious to know the answer.

'OK,' I replied - a little uneasily.

He smiled now and said in a very deliberate, almost staccato voice: 'The single worst moment of my life... was the moment I was born.' And, we had officially begun my sit-down interview with Dr. Jack Kevorkian."

That's just part of Dr. Sanjay Gupta's interview with Kevorkian.  Gupta spent more than two hours with the infamous doctor who expressed no regrets about his life.  Read the full account here.

Parental enforcement, exercise help kids cut 'screen time'

By Ann J. Curley
CNN Medical Assignment Manager

Children whose parents keep consistent rules about how much screen time their children are allowed are less likely to exceed the recommended limits, a new study has found. The study also found that children and teens who were involved in physical activities were at lower odds for going over the limits for screen time. The findings are published in the June 14 issue of the journal Pediatrics.

Previous studies have had mixed results about the effects of physical activity and this study found consistent benefit between involvement in physical activity and the amount of time kids spent in front of the screen.

Cancer survivors skipping medical care

By Trisha Henry
CNN Medical Producer

Cancer survivors are more likely to forgo or delay medical treatment because of health care costs, according to a new study published in the journal Cancer.

Even though it puts their long-term health and well-being at risk, "two million U.S. cancer survivors did not get one or more medical services because of financial concerns,"  says study author Dr. Kathryn Weaver of the Wake Forest University Baptist Medical Center. In general, she says, cancer survivors under the age of 65 were almost twice as likely to delay or forgo all types of care, compared with adults with no cancer history in the same age group.
