With cell phones, tablets, and laptops, children have more ways than ever to immerse themselves in the digital world. But as a new study finds, too much time spent in front of a screen could have consequences for a child’s intellectual development, Science News reports.

For a paper published in Lancet Child & Adolescent Health, researchers extracted data from the 10-year, longitudinal Adolescent Brain Cognitive Development study. They focused on the daily activities of 4524 American children, aged 8 to 11, that took place between September 1, 2016 and September 15, 2017. The team analyzed how well the respondents adhered to recommended guidelines for physical activity, recreational screen time, and sleep duration.

Researchers found that kids who spent more than two hours in front of a screen each day performed worse on memory, language, and other brain activity tests than kids who came in under that threshold. The participants averaged 3.6 hours a day interacting with screens. Subjects that fell under the two-hour mark recorded 4 percent higher scores on thinking tests than kids who spent more time on devices.

The result was part of a larger effort looking at the potential effects of adhering to Canadian 24-Hour Movement Guidelines for Children and Youth, which recommends an hour of exercise daily, less than two hours of screen time, and nine to 11 hours of sleep for children aged 5 to 13. Just 5 percent of subjects met all three recommendations, while 71 percent met at least one recommendation. The findings indicates that lack of sleep, too little physical activity, and idling in front of screens may be too common for children's wellbeing.

Researchers cautioned that the study shows data for only a specific time frame, and it does not demonstrate a causative relationship between screen time and poor cognition (it’s possible that smarter kids elect to spend less time on devices). Nor did the study examine whether watching or interacting with educational content made a difference over entertainment content. It does, however, provide some compelling data that kids might benefit from spending less time streaming and more time moving.

A Generic EpiPen Coming in Early 2019 Could Save You Money

For an incredibly common, life-saving medication, EpiPens (epinephrine auto-injectors) are surprisingly difficult for many consumers to get ahold of. Their cost has skyrocketed in recent years from less than $100 for a pack of two to more than $600. They’ve gotten so expensive that some EMTs have resorted to using syringes to manually administer epinephrine rather than purchasing the standard auto-injectors, which are almost exclusively made by the pharmaceutical company Mylan. Generic options have been slow to come to market, but according to Business Insider, a recently approved EpiPen rival is coming in the first few months of 2019, and it could save consumers a significant chunk of change.

The drug’s developers have had an unusually hard time getting the new EpiPen alternative, called Symjepi, onto store shelves. The drug was approved in 2017, but the company, Adamis Pharmaceuticals, had trouble finding investors. Now, Novartis, the Swiss-based pharmaceutical giant that manufactures drugs like Ritalin, is releasing the drug through its Sandoz division (perhaps most famous for it role in discovering LSD in the 1930s).

Symjepi will cost $250 out-of-pocket for a pack of two doses. That’s 16.6 percent less than the Mylan-authorized generic EpiPen or Teva’s generic EpiPen, which both sell for $300. It differs a bit from its rivals, though, in that it’s a pre-filled, single-dose syringe rather than a spring-loaded auto-injector. Auto-injectors are plastic, pen-like devices that keep the needle shielded until the moment of injection, and are specifically designed to help make it easier for untrained (even squeamish) people to use in an emergency. With this version, patients will need to remove a needle cap and inject the needle. Just like the EpiPen, though, it’s designed to be injected in the upper thigh, through clothing if necessary.

If you have health insurance, the difference in cost may not matter as much for you as a consumer, depending on your plan. (I personally picked up a two-pack of Mylan-authorized generic Epipens at CVS recently for $0, using a manufacturer’s Epipen coupon to knock down what would have been a $10 copay.) But it will matter considerably for those with high-deductible plans and to insurers, which, when faced with high costs, eventually pass those costs on to the consumer either through higher co-pays or higher premiums. It also affects agencies that buy EpiPens for emergency use, like local fire departments. And since EpiPens expire after just a year, the costs add up.

However, there’s currently a shortage of EpiPens on the market, according to the FDA, making it more important than ever to have other epinephrine drugs available to those at risk for serious allergic reactions.

Brain-Eating Amoeba Kills Seattle Woman Who Used Tap Water in Her Neti Pot

If you use a neti pot to clear out your sinuses, there's one important rule you should always follow: Don't fill it with tap water. Doing so could land you a sinus infection, or worse, a potentially fatal disease caused by a brain-eating amoeba. Although the latter scenario is exceptionally rare, a 69-year-old woman in Seattle died from doing just that, The Seattle Times reports. Experts are also warning that these infections could become more common as temperatures in the northern hemisphere continue to rise.

Physicians at Seattle's Swedish Medical Center initially thought the woman had a brain tumor. She was brought into the emergency room following a seizure, and a CT scan of her brain seemed to reveal a tumor-like mass. The only other known symptom she had was a red sore on her nose, which was previously misdiagnosed as rosacea. When surgeons operated on her the following day, they noticed that "a section of her brain about the size of a golf ball was bloody mush," neurosurgeon Dr. Charles Cobbs told The Seattle Times. "There were these amoeba[e] all over the place just eating brain cells. We didn't have any clue what was going on, but when we got the actual tissue we could see it was the amoeba."

She died a month later of an infection called granulomatous amoebic encephalitis (GAE), according to a recent case report published in the International Journal of Infectious Diseases. The disease is caused by a single-celled amoeba called Balamuthia mandrillaris, and it's extremely deadly. Of the 109 cases between 1974 and 2016, 90 percent were fatal.

According to the FDA, some bacteria and amoebae in tap water are safe to swallow because acid in the stomach kills them. However, when they enter the nasal cavity, they can stay alive for long periods of time and travel up to the brain, where they start eating their way through tissue and cells. Another brain-eating amoeba called Naegleria fowleri can cause a similar disease, except it acts faster and can cause death in just a few days. Although it's also rare, it's usually found in warm freshwater, and infections start by getting contaminated water up one's nose while swimming or by using a nose irrigation device filled with tap water.

Dr. Cynthia Maree, an infectious disease doctor at the Swedish Medical Center, said the changing environment could facilitate the spread of these infections. "I think we are going to see a lot more infections that we see south (move) north, as we have a warming of our environment," Maree says. Researchers say these amoebae are still little-understood. Future studies would need to be conducted to learn more about the risk factors involved.
