We’re gonna need a bigger meth lab
In case you’ve been living under a rock for the past 15 years, the TV show “Breaking Bad” details the spiraling rise and downfall of a high school chemistry teacher who, after developing a case of terminal lung cancer, starts producing methamphetamine to provide for his family in response to the steep cost of treatment for his cancer.
Meanwhile, here in 2023 in the real world, we have Paul Davis, a retired physician in Ohio, who’s being forced to choose between an expensive cancer treatment and bankrupting his family, since Medicare’s decided it doesn’t want to cover the cost. Hey, we’ve seen this one before!
A bit of backstory: In November 2019, Dr. Davis was diagnosed with uveal melanoma, a very rare type of cancer that affects eye tissue. The news got worse in 2022 when the cancer spread to his liver, a move which typically proves fatal within a year. However, in a stroke of great news, the Food and Drug Administration approved the drug Kimmtrak earlier that year, which could be used to treat his cancer. Not cure, of course, but it would give him more time.
His initial treatments with the drug went fine and were covered, but when he transferred his care from a hospital in Columbus to one closer to home, big problem. Medicare decided it didn’t like that hospital and abruptly cut off coverage, denying the local hospital’s claims. That leaves Dr. Davis on the hook for his cancer treatment, and it’s what you might call expensive. Expensive to the tune of $50,000.
A week.
Apparently the coding the local hospital submitted was wrong, indicating that Dr. Davis was receiving Kimmtrak for a type of cancer that the FDA hadn’t approved the drug for. So until the government bureaucracy works itself out, his treatment is on hold, leaving all his faith in Medicare working quickly to rectify its mistake. If it can rectify its mistake. We’re not hopeful.
And in case you were wondering, if Dr. Davis wanted to go full Walter White, the average street price of meth is about $20-$60 per gram, so to pay for his treatment, he’d need to make at least a kilogram of meth every week. That’s, uh, quite a lot of illegal drug, or what we here at the LOTME office would call a fun Saturday night.
When you give a mouse a movie
Researchers have been successfully testing Alzheimer drugs on mice for years, but none of the drugs has proved successful in humans. Recent work, however, might have found the missing link, and it’s a combination no one ever thought of before: mice and movies.
Turns out that Orson Welles’ 1958 film noir classic “Touch of Evil” tapped a part of the mouse brain that has been overlooked: the hippocampus, which is crucial for learning and memory. Previous researchers thought it was just used as a kind of GPS system, but that’s only partially true.
Not only did the mice choose to pay attention to the movie clip, but the hippocampus responded to the visual stimuli only when the rodents saw the scenes from the clip later in the order that they were presented and not in a scrambled order. These findings represent a “major paradigm shift” in studying mouse recall, Mayank Mehta, PhD, of the University of California, Los Angeles, said in a statement from the school.
This breakthrough could run parallel to Alzheimer’s patients struggling with similar defects. “Selective and episodic activation of the mouse hippocampus using a human movie opens up the possibility of directly testing human episodic memory disorders and therapies using mouse neurons, a major step forward,” said coauthor Chinmay Purandare, PhD, who is now at the University of California, San Francisco.
Who would have thought that a classic film would help advance Alzheimer research?
A less human way to study mosquitoes
We here at LOTME have a history with mosquitoes. We know they don’t like us, and they know that we don’t like them. Trust us, they know. So when humans gain a little ground in the war against the buzzy little bloodsuckers, we want to share the joy.
To know the enemy, scientists have to study the enemy, but there is a problem. “Many mosquito experiments still rely on human volunteers and animal subjects,” bioengineering graduate student Kevin Janson, said in a statement from Rice University. Most people don’t like being bitten by mosquitoes, so that kind of testing can be expensive.
Is there a way to automate the collection and processing of mosquito behavior data using inexpensive cameras and machine-learning software? We’re glad you asked, because Mr. Janson and the research team, which includes bioengineers from Rice and tropical medicine experts from Tulane University, have managed to eliminate the need for live volunteers by using patches of synthetic skin made with a 3D printer.
“Each patch of gelatin-like hydrogel comes complete with tiny passageways that can be filled with flowing blood” from a chicken, sheep, or cow, they explained, and proof-of-concept testing showed that mosquitoes would feed on hydrogels without any repellent and stay away from those treated with a repellent.
To conduct the feeding tests, the blood-infused hydrogels are placed in a clear plastic box that is surrounded by cameras.
A bunch of mosquitoes are then tossed in the box and the cameras record all their insect activities: how often they land at each location, how long they stay, whether or not they bite, how long they feed, etc. Humans don’t have to watch and don’t have to be food sources.
Humans don’t have to be food sources, and we just pictured the future of mosquito control. Imagine a dozen Arnold Schwarzenegger–style Terminators, covered in 3D-printed skin, walking through your neighborhood in the summer while wearing sweat-soaked, brightly colored clothing. The mosquitoes wouldn’t be able to stay away, but guess what? They’re feeding off robots with nonhuman skin and nonhuman blood, so we win. It’s good to have a cerebral cortex.
Getting medieval on brain surgery
Let’s get one thing clear: The so-called “Dark Ages” were not nearly as dark as they’re made out to be. For one thing, there’s a world beyond Western Europe. The Roman Empire didn’t collapse everywhere. But even in Western Europe, the centuries between the fall of Rome and the Renaissance were hardly lacking in cultural development.
That said, we wouldn’t want to be in the position of the seventh-century noblewoman whose remains were recently uncovered in a Byzantine fortress in central Italy with multiple cross-shaped incisions in her skull. Yes, this unfortunate woman underwent at least two brain surgeries.
Then again, maybe not. Nothing like it had been discovered at the site, and while the markings – signs of a procedure called trepanation – can be surgical in nature, there are other explanations. For example, the Avar people practiced ritual trepanation during the same time period, but they were hundreds of miles away in the Carpathian mountains, and there was no evidence to support that a different form of ritualistic trepanation ever took place in Byzantine-era Italy.
The investigators then moved on to a form of judicial punishment called decalvatio, which involves mutilation by scalping. Look, the Dark Ages weren’t dark, but no one said they were fun. Anyway, this was discarded, since decalvatio was only meted out to soldiers who deserted the battlefield.
That brings us back to surgery. While one of the trepanations was fully engraved into her skull, indicating that the woman died soon after the surgery, she also bore indications of a healed trepanation. A 50% success rate isn’t terrible for our medieval surgeon. Sure, the Incas managed 80%, but even during the Civil War brain surgery only had a 50% success rate. And that’s the end of the story, nothing more to say about our medieval Italian woman.
Nope. Nothing at all.
Fine. While a surgical procedure was deemed most likely, the study investigators found no direct evidence of a medical condition. No trauma, no tumor, nothing. Just a couple of suggestions of “a systemic pathological condition,” they said. Okay, we swear, it really wasn’t that bad in the Middle [Editor’s note: Approximately 5,000 more words on medieval culture not included. This is a medical column, thank you very much.]
