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.

Why Does Scratching Make Itching Worse?

It feels like a biological blooper: A persistent itch is made worse by scratching, the one thing that provides instantaneous relief. Evolutionary biologists have proposed that the relationship between scratching and itching developed when disease-carrying parasites and insects bit humans, causing itching skin; scratching brushed the bugs away. Anyone suffering from a mosquito bite can understand that connection.

There’s no simple answer for why skin that has just been scratched becomes even itchier, but researchers have identified some mechanisms behind the irritating phenomenon.

Why Scratching an Itch Doesn't Help

Our sensory neurons are constantly bombarded with stimuli, so some sensations take precedence over others. Sensory signals of one type can be overridden by signals of other types if the latter are strong enough. The overridden signals don’t even reach the brain—they’re stopped by specific neurons in the spinal cord. In this way, the pain caused by scratching is often sufficient to drown out the itch—but only temporarily.

Cells in the brain stem produce the neurotransmitter serotonin, which quells pain. But according to Zhou-Feng Chen, Ph.D., director of the Center for the Study of Itch at Washington University School of Medicine in St. Louis, Missouri, serotonin has an additional function. His group has found that as the serotonin spreads through the spinal cord, it can activate neurons that transmit itch signals to the brain, compelling us to scratch even more.

Each time we scratch, we put this cycle in motion. The increasing amount of serotonin may even make us scratch harder, until the urge to scratch becomes detached from any itch trigger on the skin. “It’s to try to suppress the itchy sensation, which occurs in your brain,” Chen tells Mental Floss. By this mechanism, itches can even become chronic.

Serotonin signaling isn’t the only way scratching worsens an itch; harm to the skin caused by scratching is another contributor. “When the skin barrier is irritated or further damaged, it releases certain pro-inflammatory factors that can directly aggravate itch by stimulating the sensory nerve fibers,” Brian Kim, M.D., co-director of the Center for the Study of Itch, tells Mental Floss. Those factors can also activate your immune system, and some types of immune cells around the affected area may produce chemicals that induce itch.

The very idea of scratching can also be a trigger. Chen’s research group reported last year that mice appear susceptible to scratching when they see other mice do the same. “Itching is actually contagious between people, between animals, and in your body itself,” Chen says. “When you scratch one place, you quickly want to scratch another area.” Scratching doesn’t just make itch more intense—it sometimes also causes the sensation to spread.

Relief for Itching

In mild cases, it may be possible to resist scratching through sheer force of will—but that’s not usually a long-term solution.

“I always feel bad because a lot of people say to patients, ‘Don’t scratch, don’t scratch,’ but that’s very challenging,” Kim tells Mental Floss. He says he tries to determine the cause of a person’s itchiness first. If it’s caused by an underlying medical problem, such as infestation with lice or liver disease, managing that issue may resolve the itch. Even if the underlying problem can’t be cured, there are medications that can calm itch in certain circumstances, such as antihistamines for allergy-induced itch and topical corticosteroids for itch caused by certain skin conditions, including eczema.

For now, drugs like these may be our best weapons against itching. “I think itch is often viewed as quirky, not serious, or embarrassing,” Kim says, which explains why there’s little research on itch despite its impact on our lives. Unfortunately, that coveted scratch in a bottle remains out of reach.

Scientists at UC San Diego Want You to Mail Them Your Poop

Poop. It’s fun to say, funny to talk about, and makes for an all-purpose emoji. But who wants to actually handle it?

Now, researchers of the American Gut Project at the University of California, San Diego, may be giving people new motivations to not only retain a stool sample, but pack it up and ship it to them. According to Inside Science, a team led by biologist Rob Knight is currently welcoming fecal samples from the public at large to analyze their microbiome profiles.

The microbiome is the assembly of bacteria, fungi, and other organisms that live in and on our bodies, which can change in response to lifestyle habits like diet and exercise. Recent research suggests that some microbiome profiles may make people predisposed to conditions like obesity and cancer, and might even influence our mental health. Altering the microbiome may have potentially beneficial health effects, which is why researchers like Knight are looking to collect data—in this case, poop.

“Your microbiome weighs about as much as your brain does—you're talking about a couple of pounds of material,” Knight told Inside Science. “And it certainly has more cells, way more genes, arguably as much complexity as your brain. And we're just starting to understand the far-reaching effects that it has on the rest of your body.”

Knight says that over 10,000 people have already donated their excrement for science as part of the project. And it's already producing results. In the first published study of the American Gut Project's work, which appeared in the American Society for Microbiology's journal mSystems in May 2018, the researchers found that plant-heavy diets led to a more diverse bacterial colony in stomachs than people who ate comparatively fewer types of greens. Their data also showed some preliminary evidence that people with mental health complaints tended to have similar microbiomes as people who reported the same issues.

Knight and his colleagues would love to analyze your poop in an effort to compile more information, but there is a catch: Donors have to pay a $99 fee to join the project, an informal kind of crowdfunding that keeps the research financed. If you submit a sample—basically a poop swab taken from your used toilet tissue—the team at Human Gut will send you a personalized microbiome profile and an assessment of how your gut flora compares with the rest of the population. For incrementally larger fees, you might be able to see how your diet, level of exercise, and family members' flora affect your microbiome at finer resolutions. They’ll even test your dog’s donations.

You can join the effort here. The future of poop research thanks you for your participation.
