The best part of waking up is placebo in your cup

Coffee makes the world go round. It’s impossible to picture any workplace without a cast of forlorn characters huddled around the office coffee maker on a Monday morning, imbibing their beverage du jour until they’ve been lifted out of their semi-zombified stupor.

Millions upon millions of people swear by their morning coffee. And if they don’t get that sweet, sweet caffeine boost, they’ll make Garfield and the Boomtown Rats’ opinions of Mondays look tame. And it only makes sense that they’d believe that. After all, caffeine is a stimulant. It helps your brain focus and kicks it into overdrive. Of course drinking a beverage full of caffeine wakes you up. Right?

Not so fast, a group of Portuguese researchers say. That morning cup of coffee? It may actually be a placebo. Cue the dramatic sound effect.

Here’s the scoop: After recruiting a group of coffee drinkers (at least one cup a day), the researchers kept their test subjects off of coffee for at least 3 hours, then performed a brief functional MRI scan on all test subjects. Half an hour later, study participants received either a standard cup of coffee or pure caffeine. Half an hour after consuming their respective study product, the subjects underwent a second MRI.

As expected, both people who consumed coffee and those who consumed pure caffeine showed decreased connectivity in the default mode network after consumption, indicating preparation in the brain to move from resting to working on tasks. However, those who had pure caffeine did not show increased connectivity in the visual and executive control networks, while those who had coffee did. Simply put, caffeine may wake you up, but it doesn’t make you any sharper. Only coffee gets you in shape for that oh-so-important Monday meeting.

This doesn’t make a lot of sense. How can the drug part of coffee not be responsible for every effect the drink gives you? That’s where the placebo comes in, according to the scientists. It’s possible the effect they saw was caused by withdrawal – after just 3 hours? Yikes, hope not – but it’s more likely it comes down to psychology. We expect coffee to wake us up and make us ready for the day, so that’s exactly what it does. Hey, if that’s all it takes, time to convince ourselves that eating an entire pizza is actually an incredibly effective weight loss tool. Don’t let us down now, placebo effect.
 

Bread, milk, toilet paper, AFib diagnosis

Now consider the shopping cart. It does its job of carrying stuff around the store well enough, but can it lift you out of a semi-zombified stupor in the morning? No. Can it identify undiagnosed atrial fibrillation? Again, no.

shopping_cart_woman_web.jpg

Not so fast, say the investigators conducting the SHOPS-AF (Supermarket/Hypermarket Opportunistic Screening for Atrial Fibrillation) study. They built a better shopping cart. Except they call it a trolley, not a cart, since the study was conducted in England, where they sometimes have funny names for things.

Their improved shopping trolley – we’re just going to call it a cart from here on – has an electrocardiogram sensor embedded into the handlebar, so it can effectively detect AFib in shoppers who held it for at least 60 seconds. The sensor lights up red if it detects an irregular heartbeat and green if it does not. Let’s see a cup of coffee do that.

They put 10 of these modified carts in four supermarkets in Liverpool to see what would happen. Would shoppers be able to tell that we secretly replaced the fine coffee they usually serve with Folger’s crystals? Oops. Sorry about that. Coffee on the brain, apparently. Back to the carts.

A total of 2,155 adult shoppers used one of the carts over 2 months, and electrocardiogram data were available for 220 participants who either had a red light on the sensor and/or an irregular pulse that suggested atrial fibrillation. After further review by the SHOPS-AF cardiologist, AFib was diagnosed in 59 shoppers, of whom 39 were previously undiagnosed.

They’re already working to cut the scan time to 30 seconds for SHOPS-AF II, but we’re wondering about a possible flaw in the whole health-care-delivery-through-shopping-cart scenario. When we go to the local super/hyper/megamart, it seems like half of the people trundling up and down the aisles are store employees filling orders for customers who won’t even set foot inside. Is the shopping cart on its way out? Maybe. Who wants to tell the SHOPS-AF II team? Not us.
 

Put pneumonia where your mouth is

Getting dentures does not mean the end of dental care. If anything, new research reveals a huge reason for staying on top of one’s denture care: pneumonia.

denture_web.jpg

It all started with swabs. Scientists in the United Kingdom took mouth, tongue, and denture specimens from frail elderly hospital patients who had pneumonia and wore dentures and from similar patients in care homes who wore dentures and did not have pneumonia. When they compared the microbial populations of the two groups, the investigators found about 20 times the number of respiratory pathogens on the dentures of those with pneumonia.

The research team suggested that dentures may play a role in causing pneumonia, but lead author Josh Twigg, BDS, PhD, also noted that “you certainly couldn’t say that people got pneumonia because they were wearing dentures. It’s just showing that there is an association there.” Improper cleaning, though, could lead to microbial colonization of the dentures, and patients could be inhaling those microbes into their lungs, thereby turning a dental issue into a respiratory issue.

More research needs to be done on the association between dentures and pneumonia, but Dr. Twigg hoped that the results of this study could be presented to the public. The message? “It is important to clean dentures thoroughly” and visit the dentist regularly, he said, but the best way to prevent denture-related infections is to avoid needing to wear dentures entirely.

Low-calorie tastes sweeter with a little salt

Diet and sugar-free foods and drinks seem like a good idea, but it’s hard to get past that strange aftertaste, right? It’s the calling card for the noncaloric aspartame- and stevia-containing sweeteners that we consume to make us feel like we can have the best of both worlds.

That weird lingering taste can be a total turn-off for some (raises hand), but researchers have found an almost facepalm solution to the not-so-sweet problem, and it’s salt.

salt_spoon_web2.jpg

Now, the concept of sweet and salty is not a far-fetched partnership when it comes to snack consumption (try M&Ms in your popcorn). The researchers at Almendra, a manufacturer of stevia sweeteners, put that iconic flavor pair to the test by adding mineral salts that have some nutritional value to lessen the effect of a stevia compound, rebaudioside A, found in noncaloric sweeteners.

The researchers added in magnesium chloride, calcium chloride, and potassium chloride separately to lessen rebaudioside A’s intensity, but they needed so much salt that it killed the sweet taste completely. A blend of the three mineral salts, however, reduced the lingering taste by 79% and improved the real sugar-like taste. The researchers tried this blend in reduced-calorie orange juice and a citrus-flavored soft drink, improving the taste in both.

The salty and sweet match comes in for the win once again. This time helping against the fight of obesity instead of making it worse.

Pseudomonas’ Achilles’ heel is more of an Achilles’ genetic switch

Today, on the long-awaited return of “Bacteria vs. the World,” we meet one of the rock stars of infectious disease.

LOTME: Through the use of imaginary technology, we’re talking to Pseudomonas aeruginosa. Thanks for joining us on such short notice, after Neisseria gonorrhoeae canceled at the last minute.

P. aeruginosa: No problem. I think we can all guess what that little devil is up to.

163997_pseudomonas_web.jpg

LOTME: Bacterial resistance to antibiotics is a huge problem for our species. What makes you so hard to fight?

P. aeruginosa: We’ve been trying to keep that a secret, actually, but now that researchers in Switzerland and Denmark seem to have figured it out, I guess it’s okay for me to spill the beans.

LOTME: Beans? What do beans have to do with it?

P. aeruginosa: Nothing, it’s just a colloquial expression that means I’m sharing previously private information.

LOTME: Sure, we knew that. Please, continue your spilling.

P. aeruginosa: The secret is … Well, let’s just say we were a little worried when the Clash released “Should I Stay or Should I Go” back in the 1980s.

LOTME: The Clash? Now we’re really confused.

P. aeruginosa: The answer to their question, “Should I stay or should I go? is yes. Successful invasion of a human is all about division of labor. “While one fraction of the bacterial population adheres to the mucosal surface and forms a biofilm, the other subpopulation spreads to distant tissue sites,” is how the investigators described it. We can increase surface colonization by using a “job-sharing” process, they said, and even resist antibiotics because most of us remain in the protective biofilm.

LOTME: And they say you guys don’t have brains.

P. aeruginosa: But wait, there’s more. We don’t just divide the labor randomly. After the initial colonization we form two functionally distinct subpopulations. One has high levels of the bacterial signaling molecule c-di-GMP and stays put to work on the biofilm. The other group, with low levels of c-di-GMP, heads out to the surrounding tissue to continue the colonization. As project leader Urs Jenal put it, “By identifying the genetic switch, we have tracked down the Achilles heel of the pathogen.”

LOTME: Pretty clever stuff, for humans, anyway.

P. aeruginosa: We agree, but now that you know our secret, we can’t let you share it.

LOTME: Wait! The journal article’s already been published. Your secret is out. You can’t stop that by infecting me.

P. aeruginosa: True enough, but are you familiar with the fable of the scorpion and the frog? It’s our nature.

LOTME: Nooooo! N. gonorrhoeae wouldn’t have done this!
 

What a pain in the Butt

Businesses rise and businesses fall. We all know that one cursed location, that spot in town where we see businesses move in and close up in a matter of months. At the same time, though, there are also businesses that have been around as long as anyone can remember, pillars of the community.

Corydon, IN., likely has a few such long-lived shops, but it is officially down one 70-year-old family business as of late April, with the unfortunate passing of beloved local pharmacy Butt Drugs. Prescription pick-up in rear.

Butt_Drugs_web.jpg

The business dates back to 1952, when it was founded as William H. Butt Drugs. We’re sure William Butt was never teased about his last name. Nope. No one would ever do that. After he passed the store to his children, it underwent a stint as Butt Rexall Drugs. When the shop was passed down to its third-generation and ultimately final owner, Katie Butt Beckort, she decided to simplify the name. Get right down to the bottom of things, as it were.

Butt Drugs was a popular spot, featuring an old-school soda fountain and themed souvenirs. According to Ms. Butt Beckort, people would come from miles away to buy “I love Butt Drugs” T-shirts, magnets, and so on. Yes, they knew perfectly well what they were sitting on.

So, if was such a hit, why did it close? Butt Drugs may have a hilarious name and merchandise to match, but the pharmacy portion of the pharmacy had been losing money for years. You know, the actual point of the business. As with so many things, we can blame it on the insurance companies. More than half the drugs that passed through Butt Drugs’ doors were sold at a loss, because the insurance companies refused to reimburse the store more than the wholesale price of the drug. Not even a good butt drug could clear up that financial diarrhea.

And so, we’ve lost Butt Drugs forever. Spicy food enthusiasts, coffee drinkers, and all patrons of Taco Bell, take a moment to reflect and mourn on what you’ve lost. No more Butt Drugs to relieve your suffering. A true kick in the butt indeed.

Businesses rise and businesses fall. We all know that one cursed location, that spot in town where we see businesses move in and close up in a matter of months. At the same time, though, there are also businesses that have been around as long as anyone can remember, pillars of the community.

Corydon, IN., likely has a few such long-lived shops, but it is officially down one 70-year-old family business as of late April, with the unfortunate passing of beloved local pharmacy Butt Drugs. Prescription pick-up in rear.

Butt_Drugs_web.jpg

The business dates back to 1952, when it was founded as William H. Butt Drugs. We’re sure William Butt was never teased about his last name. Nope. No one would ever do that. After he passed the store to his children, it underwent a stint as Butt Rexall Drugs. When the shop was passed down to its third-generation and ultimately final owner, Katie Butt Beckort, she decided to simplify the name. Get right down to the bottom of things, as it were.

Butt Drugs was a popular spot, featuring an old-school soda fountain and themed souvenirs. According to Ms. Butt Beckort, people would come from miles away to buy “I love Butt Drugs” T-shirts, magnets, and so on. Yes, they knew perfectly well what they were sitting on.

So, if was such a hit, why did it close? Butt Drugs may have a hilarious name and merchandise to match, but the pharmacy portion of the pharmacy had been losing money for years. You know, the actual point of the business. As with so many things, we can blame it on the insurance companies. More than half the drugs that passed through Butt Drugs’ doors were sold at a loss, because the insurance companies refused to reimburse the store more than the wholesale price of the drug. Not even a good butt drug could clear up that financial diarrhea.

And so, we’ve lost Butt Drugs forever. Spicy food enthusiasts, coffee drinkers, and all patrons of Taco Bell, take a moment to reflect and mourn on what you’ve lost. No more Butt Drugs to relieve your suffering. A true kick in the butt indeed.

Three big bumps on the weight-loss journey

The search for the Holy Grail. The destruction of the One Ring. The never-ending struggle to Lose Weight.

Like most legendary quests, weight loss is a journey, and we need support to help us achieve our goal. Maybe it’s gaining a new workout partner or finding a similarly-goaled Facebook Group. For a lot of people, it’s as simple as your friends and family. A recent study, however, suggests that the people closest to you may be your worst weight-loss enemies, and they might not even know it.

meal_group_web.jpg

Researchers at the University of Surrey reviewed the literature on the positives and negatives of social support when it comes to weight loss and identified three types of negative effects: acts of sabotage, feeding behavior, and collusion.

Let’s start with the softest of intentions and work our way up. Collusion is the least negative. Friends and family may just go with the flow, even if it doesn’t agree with the goals of the person who’s trying to lose weight. It can even happen when health care professionals try to help their patients navigate or avoid obesity, ultimately killing with kindness, so to speak.

Next up, feeding behavior. Maybe you know someone whose love language is cooking. There are also people who share food because they don’t want to waste it or because they’re trying to be polite. They act out of the goodness of their hearts, but they’re putting up roadblocks to someone’s goals. These types of acts are usually one-sided, the researchers found. Remember, it’s okay to say, “No thanks.”

The last method, sabotage, is the most sinister. The saboteur may discourage others from eating healthy, undermine their efforts to be physically active, or take jabs at their confidence or self-esteem. Something as simple as criticizing someone for eating a salad or refusing to go on a walk with them can cause a setback.

“We need to explore this area further to develop interventions which could target family and friends and help them be more supportive in helping those they are close to lose weight,” said lead author Jane Odgen, PhD, of the University of Surrey, Guildford, England.

Like we said before, weight loss is a journey. The right support can only improve the odds of success.
 

Robots vs. mosquitoes

If there’s one thing robots are bad at, it’s giving solid mental health advice to people in crisis. If there’s one thing robots are very, very good at, it’s causing apocalypses. And joyous day for humanity, this time we’re not the ones being apocalypsed.

Taiwan has a big mosquito problem. Not only do the mosquitoes in Taiwan carry dengue – among other dangerous diseases – but they’ve urbanized. Not urbanized in the sense that they’ve acquired a taste for organic coffee and avocado toast (that would be the millennial mosquito, a separate but even more terrifying creature), but more that they’ve adapted to reproduce literally anywhere and everywhere. Taiwanese mosquitoes like to breed in roadside sewer ditches, and this is where our genocidal robot comes in.

To combat the new, dangerous form of street-savvy mosquito, researchers built a robot armed with both insecticide and high-temperature, high-pressure water jets and sent it into the sewers of Kaohsiung City. The robot’s goal was simple: Whenever it came across signs of heavy mosquito breeding – eggs, larvae, pupae, and so on – the robot went to work. Utilizing both its primary weapons, the robot scrubbed numerous breeding sites across the city clean.

The researchers could just sit back and wait to see how effective their robot was. In the immediate aftermath, at various monitoring sites placed alongside the ditches, adult mosquito density fell by two-thirds in areas targeted by the robot. That’s nothing to sniff at, and it does make sense. After all, mosquitoes are quite difficult to kill in their adult stage, why not target them when they’re young and basically immobile?

The researchers saw promise with their mosquito-killing robot, but we’ve noticed a rather large issue. Killing two-thirds of mosquitoes is fine, but the third that’s left will be very angry. Very angry indeed. After all, we’re targeting the mosquito equivalent of children. Let’s hope our mosquito Terminator managed to kill mosquito Sarah Connor, or we’re going to have a big problem on our hands a bit later down the line.
 

This is knot what you were expecting

Physicians who aren’t surgeons probably don’t realize it, but the big thing that’s been getting between the knot-tying specialists and perfect suturing technique all these years is a lack of physics. Don’t believe us? Well, maybe you’ll believe plastic surgeon Samia Guerid, MD, of Lausanne, Switzerland: “The lack of physics-based analysis has been a limitation.” Nuff said.

knot_surgical_web.jpg

That’s not enough for you, is it? Fine, we were warned.

Any surgical knot, Dr. Guerid and associates explained in a written statement, involves the “complex interplay” between six key factors: topology, geometry, elasticity, contact, friction, and polymer plasticity of the suturing filament. The strength of a suture “depends on the tension applied during the tying of the knot, [which] permanently deforms, or stretches the filament, creating a holding force.” Not enough tension and the knot comes undone, while too much snaps the filament.

For the experiment, Dr. Guerid tied a few dozen surgical knots, which were then scanned using x-ray micro–computed tomography to facilitate finite element modeling with a “3D continuum-level constitutive model for elastic-viscoplastic mechanical behavior” – no, we have no idea what that means, either – developed by the research team.

That model, and a great deal of math – so much math – allowed the researchers to define a threshold between loose and tight knots and uncover “relationships between knot strength and pretension, friction, and number of throws,” they said.

But what about the big question? The one about the ideal amount of tension? You may want to sit down. The answer to the ultimate question of the relationship between knot pretension and strength is … Did we mention that the team had its own mathematician? Their predictive model for safe knot-tying is … You’re not going to like this. The best way to teach safe knot-tying to both trainees and robots is … not ready yet.

The secret to targeting the knot tension sweet spot, for now, anyway, is still intuition gained from years of experience. Nobody ever said science was perfect … or easy … or quick.

Sowing the seeds of cancer prevention

Are you looking to add to your quality of life, even though pets are not your speed? Might we suggest something with lower maintenance? Something a little greener?

Indoor plants can purify the air that comes from outside. Researchers at the University of Technology Sydney, in partnership with the plantscaping company Ambius, showed that a “green wall” made up of mixed indoor plants was able to suck up 97% of “the most toxic compounds” from the air in just 8 hours. We’re talking about lung-irritating, headache-inducing, cancer risk–boosting compounds from gasoline fumes, including benzene.

plants_pollution_web.jpg

Public health initiatives often strive to reduce cardiovascular and obesity risks, but breathing seems pretty important too. According to the World Health Organization, household air pollution is responsible for about 2.5 million global premature deaths each year. And since 2020 we’ve become accustomed to spending more time inside and at home.

“This new research proves that plants should not just be seen as ‘nice to have,’ but rather a crucial part of every workplace wellness plan,” Ambius General Manager Johan Hodgson said in statement released by the university.

So don’t spend hundreds of dollars on a fancy air filtration system when a wall of plants can do that for next to nothing. Find what works for you and your space and become a plant parent today! Your lungs will thank you.
 

But officer, I had to swerve to miss the duodenal ampulla

Tiny video capsule endoscopes have been around for many years, but they have one big weakness: The ingestible cameras’ journey through the GI tract is passively driven by gravity and the natural movement of the body, so they often miss potential problem areas.

endoscope_capsule_web.jpg

Not anymore. That flaw has been addressed by medical technology company AnX Robotica, which has taken endoscopy to the next level by adding that wondrous directional control device of the modern electronic age, a joystick.

The new system “uses an external magnet and hand-held video game style joysticks to move the capsule in three dimensions,” which allows physicians to “remotely drive a miniature video capsule to all regions of the stomach to visualize and photograph potential problem areas,” according to Andrew C. Meltzer, MD, of George Washington University and associates, who conducted a pilot study funded by AnX Robotica.

The video capsule provided a 95% rate of visualization in the stomachs of 40 patients who were examined at a medical office building by an emergency medicine physician who had no previous specialty training in endoscopy. “Capsules were driven by the ER physician and then the study reports were reviewed by an attending gastroenterologist who was physically off site,” the investigators said in a written statement.

The capsule operator did receive some additional training, and development of artificial intelligence to self-drive the capsule is in the works, but for now, we’re talking about a device controlled by a human using a joystick. And we all know that 50-year-olds are not especially known for their joystick skills. For that we need real experts. Yup, we need to put those joystick-controlled capsule endoscopes in the hands of teenage gamers. Who wants to go first?
 

Maybe AI isn’t ready for the big time after all

“How long before some intrepid stockholder says: ‘Hey, instead of paying doctors, why don’t we just use the free robot instead?’ ” Those words appeared on LOTME but a month ago. After all, the AI is supposed to be smarter and more empathetic than a doctor. And did we mention it’s free? Or at least extremely cheap. Cheaper than, say, a group of recently unionized health care workers.

teen_phone_bed_web.jpg

In early May, the paid employees manning the National Eating Disorders Association emergency hotline voted to unionize, as they felt overwhelmed and underpaid. Apparently, paying six people an extra few thousand a year was too much for NEDA’s leadership, as they decided a few weeks later to fire those workers, fully closing down the hotline. Instead of talking to a real person, people “calling in” for support would be met with Tessa, a wellness chatbot that would hopefully guide them through their crisis. Key word, hopefully.

In perhaps the least surprising twist of the year, NEDA was forced to walk back its decision about a week after its initial announcement. It all started with a viral Instagram post from a woman who called in and received the following advice from Tessa: Lose 1-2 pounds a week, count calories and work for a 500- to 1,000-calorie deficit, weigh herself weekly, and restrict her diet. Unfortunately, all of these suggestions were things that led to the development of the woman’s eating disorder.

Naturally, NEDA responded in good grace, accusing the woman of lying. A NEDA vice president even left some nasty comments on the post, but hastily deleted them a day later when NEDA announced it was shutting down Tessa “until further notice for a complete investigation.” NEDA’s CEO insisted they hadn’t seen that behavior from Tessa before, calling it a “bug” and insisting the bot would only be down temporarily until the triggers causing the bug were fixed.

In the aftermath, several doctors and psychologists chimed in, terming the rush to automate human roles dangerous and risky. After all, much of what makes these hotlines effective is the volunteers speaking from their own experience. An unsupervised bot doesn’t seem to have what it takes to deal with a mental health crisis, but we’re betting that Tessa will be back. As a wise cephalopod once said: Nobody gives a care about the fate of labor as long as they can get their instant gratification.
 

You can’t spell existential without s-t-e-n-t

This week, we’re including a special “bonus” item that, to be honest, has nothing to do with stents. That’s why our editor is making us call this a “bonus” (and making us use quote marks, too): It doesn’t really have anything to do with stents or health care or those who practice health care. Actually, his exact words were, “You can’t just give the readers someone else’s ****ing list and expect to get paid for it.” Did we mention that he looks like Jack Nicklaus but acts like BoJack Horseman?

Anywaaay, we’re pretty sure that the list in question – “America’s Top 10 Most Googled Existential Questions” – says something about the human condition, just not about stents:

1. Why is the sky blue?

2. What do dreams mean?

3. What is the meaning of life?

4. Why am I so tired?

5. Who am I?

6. What is love?

7. Is a hot dog a sandwich?

8. What came first, the chicken or the egg?

9. What should I do?

10. Do animals have souls?

Are you looking to add to your quality of life, even though pets are not your speed? Might we suggest something with lower maintenance? Something a little greener?

Indoor plants can purify the air that comes from outside. Researchers at the University of Technology Sydney, in partnership with the plantscaping company Ambius, showed that a “green wall” made up of mixed indoor plants was able to suck up 97% of “the most toxic compounds” from the air in just 8 hours. We’re talking about lung-irritating, headache-inducing, cancer risk–boosting compounds from gasoline fumes, including benzene.

Public health initiatives often strive to reduce cardiovascular and obesity risks, but breathing seems pretty important too. According to the World Health Organization, household air pollution is responsible for about 2.5 million global premature deaths each year. And since 2020 we’ve become accustomed to spending more time inside and at home.

“This new research proves that plants should not just be seen as ‘nice to have,’ but rather a crucial part of every workplace wellness plan,” Ambius General Manager Johan Hodgson said in statement released by the university.

So don’t spend hundreds of dollars on a fancy air filtration system when a wall of plants can do that for next to nothing. Find what works for you and your space and become a plant parent today! Your lungs will thank you.
 

But officer, I had to swerve to miss the duodenal ampulla

Tiny video capsule endoscopes have been around for many years, but they have one big weakness: The ingestible cameras’ journey through the GI tract is passively driven by gravity and the natural movement of the body, so they often miss potential problem areas.

endoscope_capsule_web.jpg

Not anymore. That flaw has been addressed by medical technology company AnX Robotica, which has taken endoscopy to the next level by adding that wondrous directional control device of the modern electronic age, a joystick.

The new system “uses an external magnet and hand-held video game style joysticks to move the capsule in three dimensions,” which allows physicians to “remotely drive a miniature video capsule to all regions of the stomach to visualize and photograph potential problem areas,” according to Andrew C. Meltzer, MD, of George Washington University and associates, who conducted a pilot study funded by AnX Robotica.

The video capsule provided a 95% rate of visualization in the stomachs of 40 patients who were examined at a medical office building by an emergency medicine physician who had no previous specialty training in endoscopy. “Capsules were driven by the ER physician and then the study reports were reviewed by an attending gastroenterologist who was physically off site,” the investigators said in a written statement.

The capsule operator did receive some additional training, and development of artificial intelligence to self-drive the capsule is in the works, but for now, we’re talking about a device controlled by a human using a joystick. And we all know that 50-year-olds are not especially known for their joystick skills. For that we need real experts. Yup, we need to put those joystick-controlled capsule endoscopes in the hands of teenage gamers. Who wants to go first?
 

Maybe AI isn’t ready for the big time after all

“How long before some intrepid stockholder says: ‘Hey, instead of paying doctors, why don’t we just use the free robot instead?’ ” Those words appeared on LOTME but a month ago. After all, the AI is supposed to be smarter and more empathetic than a doctor. And did we mention it’s free? Or at least extremely cheap. Cheaper than, say, a group of recently unionized health care workers.

teen_phone_bed_web.jpg

In early May, the paid employees manning the National Eating Disorders Association emergency hotline voted to unionize, as they felt overwhelmed and underpaid. Apparently, paying six people an extra few thousand a year was too much for NEDA’s leadership, as they decided a few weeks later to fire those workers, fully closing down the hotline. Instead of talking to a real person, people “calling in” for support would be met with Tessa, a wellness chatbot that would hopefully guide them through their crisis. Key word, hopefully.

In perhaps the least surprising twist of the year, NEDA was forced to walk back its decision about a week after its initial announcement. It all started with a viral Instagram post from a woman who called in and received the following advice from Tessa: Lose 1-2 pounds a week, count calories and work for a 500- to 1,000-calorie deficit, weigh herself weekly, and restrict her diet. Unfortunately, all of these suggestions were things that led to the development of the woman’s eating disorder.

Naturally, NEDA responded in good grace, accusing the woman of lying. A NEDA vice president even left some nasty comments on the post, but hastily deleted them a day later when NEDA announced it was shutting down Tessa “until further notice for a complete investigation.” NEDA’s CEO insisted they hadn’t seen that behavior from Tessa before, calling it a “bug” and insisting the bot would only be down temporarily until the triggers causing the bug were fixed.

In the aftermath, several doctors and psychologists chimed in, terming the rush to automate human roles dangerous and risky. After all, much of what makes these hotlines effective is the volunteers speaking from their own experience. An unsupervised bot doesn’t seem to have what it takes to deal with a mental health crisis, but we’re betting that Tessa will be back. As a wise cephalopod once said: Nobody gives a care about the fate of labor as long as they can get their instant gratification.
 

You can’t spell existential without s-t-e-n-t

This week, we’re including a special “bonus” item that, to be honest, has nothing to do with stents. That’s why our editor is making us call this a “bonus” (and making us use quote marks, too): It doesn’t really have anything to do with stents or health care or those who practice health care. Actually, his exact words were, “You can’t just give the readers someone else’s ****ing list and expect to get paid for it.” Did we mention that he looks like Jack Nicklaus but acts like BoJack Horseman?

Anywaaay, we’re pretty sure that the list in question – “America’s Top 10 Most Googled Existential Questions” – says something about the human condition, just not about stents:

1. Why is the sky blue?

2. What do dreams mean?

3. What is the meaning of life?

4. Why am I so tired?

5. Who am I?

6. What is love?

7. Is a hot dog a sandwich?

8. What came first, the chicken or the egg?

9. What should I do?

10. Do animals have souls?

Even the plague wanted to visit Stonehenge

We’re about to blow your mind: The history you learned in school was often inaccurate. Shocking, we know, so we’ll give you a minute to process this incredible news.

Better? Good. Now, let’s look back at high school European history. The Black Death, specifically. The common narrative is that the Mongols, while besieging a Crimean city belonging to the Genoese, catapulted dead bodies infected with some mystery disease that turned out to be the plague. The Genoese then brought the plague back to Italy, and from there, we all know the rest of the story.

plague_ring_web.jpg

The Black Death was certainly extremely important to the development of modern Europe as we know it, but the history books gloss over the much longer history of the plague. Yersinia pestis did not suddenly appear unbidden in a Mongol war camp in 1347. The Black Death wasn’t even the first horrific, continent-wide pandemic caused by the plague; the Plague of Justinian 800 years earlier crippled the Byzantine Empire during an expansionist phase and killed anywhere between 15 million and 100 million.

Today, though, LOTME looks even deeper into history, nearly beyond even history itself, back into the depths of early Bronze Age northern Europe. Specifically, to two ancient burial sites in England, where researchers have identified three 4,000-year-old cases of Y. pestis, the first recorded incidence of the disease in Britain.

Two of the individuals, identified through analysis of dental pulp, were young children buried at a mass grave in Somerset, while the third, a middle-aged woman, was found in a ring cairn in Cumbria. These sites are hundreds of miles apart, yet carbon dating suggests all three people lived and died at roughly the same time. The strain found is very similar to other samples of plague found across central and western Europe starting around 3,000 BCE, suggesting a single, easily spread disease affecting a large area in a relatively small period of time. In other words, a pandemic. Even in these ancient times, the world was connected. Not even the island of Britain could escape.

Beyond that though, the research helps confirm the cyclical nature of the plague; over time, it loses its effectiveness and goes into hiding, only to mutate and come roaring back. This is a story with absolutely no relevance at all to the modern world. Nope, no plagues or pandemics going around right now, no viruses fading into the background in any way. What a ridiculous inference to make.
 

Uncovering the invisible with artificial intelligence

This week in “What Else Can AI Do?” new research shows that a computer program can reveal brain injury that couldn’t be seen before with typical MRI.

The hot new AI, birthed by researchers at New York University, could potentially be a game changer by linking repeated head impacts with tiny, structural changes in the brains of athletes who have not been diagnosed with a concussion. By using machine learning to train the AI, the researchers were, for the first time, able to distinguish the brain of athletes who played contact sports (football, soccer, lacrosse) from those participating in noncontact sports such as baseball, basketball, and cross-country.

ArtificialIntelligence_web.jpg

How did they do it? The investigators “designed statistical techniques that gave their computer program the ability to ‘learn’ how to predict exposure to repeated head impacts using mathematical models,” they explained in a written statement. Adding in data from the MRI scans of 81 male athletes with no known concussion diagnosis and the ability to identify unusual brain features between athletes with and without head trauma allowed the AI to predict results with accuracy even Miss Cleo would envy.

“This method may provide an important diagnostic tool not only for concussion, but also for detecting the damage that stems from subtler and more frequent head impacts,” said lead author Junbo Chen, an engineering doctoral candidate at NYU. That could make this new AI a valuable asset to science and medicine.

There are many things the human brain can do that AI can’t, and delegation could be one of them. Examining the data that represent the human brain in minute detail? Maybe we leave that to the machine.

If you’re a surgeon doing an amputation, the list of possible assistants pretty much starts and ends in only one place: Not the closest available janitor.

That may seem like an oddly obvious thing for us to say, but there’s at least one former Mainz (Germany) University Hospital physician who really needed to get this bit of advice before he attempted an unassisted toe amputation back in October of 2020. Yes, that does seem like kind of a long time ago for us to be reporting it now, but the details of the incident only just came to light a few days ago, thanks to German public broadcaster SWR.

janitor_web.jpg

Since it was just a toe, the surgeon thought he could perform the operation without any help. The toe, unfortunately, had other plans. The partially anesthetized patient got restless in the operating room, but with no actual trained nurse in the vicinity, the surgeon asked the closest available person – that would be the janitor – to lend a hand.

The surgical manager heard about these goings-on and got to the operating room too late to stop the procedure but soon enough to see the cleaning staffer “at the operating table with a bloody suction cup and a bloody compress in their hands,” SWR recently reported.

The incident was reported to the hospital’s medical director and the surgeon was fired, but since the patient experienced no complications not much fuss was made about it at the time.

Well, guess what? It’s toe-tally our job to make a fuss about these kinds of things. Or could it be that our job, much like the surgeon’s employment and the patient’s digit, is here toe-day and gone toe-morrow?

Family physicians may have started 2022 with the COVID-19 Omicron surge, but the year seems to have ended with old issues of regulation, reimbursement, and burnout regaining their attention, according to the results of the Medscape Family Physician Compensation Report 2023.

Average compensation for the specialty, which has risen by 31% since 2015, was stagnant in 2022, showing no growth from the previous year. COVID, at least, had less of an effect on earnings, as 48% of family physicians cited pandemic-related income losses, compared with 64% in 2021, according to those who responded to Medscape’s annual survey, which was conducted from Oct. 2, 2022, to Jan. 17, 2023.

163629a_graphic_web.png

Comments from those respondents covered several areas that were already concerning physicians before the pandemic. One wrote that “decreasing Medicare reimbursement and poor payor mix destroy our income,” and another said that “patients have become rude and come with poor information from social media.” One respondent described the situation this way: “Overwhelming burnout. I had to reduce my hours to keep myself from quitting medicine completely.”

Overall physician compensation in 2022 was up by about 4% from 2021. For the 12% of the 10,011 respondents who practice family medicine, the average held at $255,000, where it had been the year before. Among the other primary care specialists, internists’ earnings were up by almost 4% and pediatricians did almost as well with a 3% increase, while ob.gyns. joined family physicians in the no-growth club, the Medscape results show.

For all physicians, average compensation in 2022 was $352,000, an increase of almost 18% since 2018. “Supply and demand is the biggest driver,” Mike Belkin, JD, of physician recruitment firm Merritt Hawkins, said in an interview. “Organizations understand it’s not getting any easier to get good candidates, and so for the most part, physicians are getting good offers.”

The lack of increase in FPs earnings among internists also included a decline of note: The disparity between mens’ and womens’ compensation dropped from 26% in 2021 to 23% in 2022. The 2022 disparity was only 16% for internists, however, even though family medicine has a considerably larger share of women (49% vs. 40%) among those surveyed, Medscape said.

163629b_graphic_web.png

Satisfaction with their compensation, on the other hand, was higher among the family physicians (50%), compared with internists (43%). In 2022, 55% of family physicians said that they had been fairly paid.

In 2022, FP respondents reported spending an average of 16.7 hours (up from 15.6 hours in 2021) each week on paperwork and administration, just below the survey leaders, physical medicine and rehabilitation (18.5 hours) and nephrology (18.1 hours) but well above anesthesiology, lowest of the 29 specialties at 9.0 hours, and the 2022 average of 15.5 hours for all physicians, Medscape said.

When asked if they would choose medicine again, 72% of family physician respondents and 73% of all physicians said yes, with emergency medicine (65%) and dermatology (86%) representing the two extremes. A question about specialty choice showed that 66% of FPs would choose it again, putting them 28th of the 29 included specialties in their eagerness to follow the same path, above only the internists (61%), Medscape reported.

Commenters among the survey respondents were not identified by specialty, but dissatisfaction on many fronts was a definite theme:

• “Our costs go up, and our reimbursement does not.”
• “Our practice was acquired by venture capital firms; they slashed costs.”
• “My productivity bonus should have come to $45,000. Instead I was paid only $15,000. Yet cardiologists and administrators who were working from home part of the year received their full bonus.”
• “I will no longer practice cookbook mediocrity.”

Satisfaction with their compensation, on the other hand, was higher among the family physicians (50%), compared with internists (43%). In 2022, 55% of family physicians said that they had been fairly paid.

In 2022, FP respondents reported spending an average of 16.7 hours (up from 15.6 hours in 2021) each week on paperwork and administration, just below the survey leaders, physical medicine and rehabilitation (18.5 hours) and nephrology (18.1 hours) but well above anesthesiology, lowest of the 29 specialties at 9.0 hours, and the 2022 average of 15.5 hours for all physicians, Medscape said.

When asked if they would choose medicine again, 72% of family physician respondents and 73% of all physicians said yes, with emergency medicine (65%) and dermatology (86%) representing the two extremes. A question about specialty choice showed that 66% of FPs would choose it again, putting them 28th of the 29 included specialties in their eagerness to follow the same path, above only the internists (61%), Medscape reported.

Commenters among the survey respondents were not identified by specialty, but dissatisfaction on many fronts was a definite theme:

• “Our costs go up, and our reimbursement does not.”
• “Our practice was acquired by venture capital firms; they slashed costs.”
• “My productivity bonus should have come to $45,000. Instead I was paid only $15,000. Yet cardiologists and administrators who were working from home part of the year received their full bonus.”
• “I will no longer practice cookbook mediocrity.”

Internists experienced many of the usual ups and downs regarding nonclinical matters in 2022: Compensation was up, but satisfaction with compensation was down; the percentage of internists who would choose another specialty was up and time spent on paperwork and administration was down only slightly.

A year that began with the COVID-19 Omicron surge ended with many of the same old issues regaining the attention of physicians, according to those who responded to Medscape’s annual compensation survey, which was conducted from Oct. 2, 2022, to Jan. 17, 2023.

163628a_graphic_web.png

“Decreasing Medicare reimbursement and poor payor mix destroy our income,” one physician wrote, and another said that “patients have become rude and come with poor information from social media.” One respondent described the situation this way: “Overwhelming burnout. I had to reduce my hours to keep myself from quitting medicine completely.”

For internists at least, some of the survey results were positive. For the 13% of the 10,011 respondents who practice internal medicine, average compensation went from $264,000 in 2021 to $273,000 in 2022, an increase of almost 4% that matched the average for all physicians. Among the other primary care specialists, pediatricians did almost as well with a 3% increase, but ob.gyns. and family physicians only managed to keep their 2022 earnings at 2021 levels.

Overall physician compensation for 2022 was $352,000, an increase of almost 18% since 2018. “Supply and demand is the biggest driver,” Mike Belkin, JD, of physician recruitment firm Merritt Hawkins, said in an interview. “Organizations understand it’s not getting any easier to get good candidates, and so for the most part, physicians are getting good offers.”

The latest increase in earnings among internists also included a decline: The disparity between mens’ and womens’ compensation dropped from 24% in 2021 to 16% in 2022. The gap was slightly larger for all physicians in 2022, with men earning about 19% more than women, and larger again among specialists at 27%, but both of those figures are lower than in recent years, Medscape said.

163628b_graphic_web.png

Satisfaction with their compensation, however, was not high for internists: Only 43% feel that they are fairly paid, coming in above only ophthalmology (42%) and infectious diseases (35%) and well below psychiatry (68%) at the top of the list, the Medscape data show. In the 2022 report, 49% of internists said that they had been fairly paid.

In another source of potential dissatisfaction, internist respondents reported spending an average of 17.9 hours each week on paperwork and administration, just below the survey leaders, physical medicine and rehabilitation (18.5 hours) and nephrology (18.1 hours) and well above anesthesiology, which was the lowest of the 29 specialties at 9.0 hours, and the 2022 average of 15.5 hours for all physicians, Medscape said. A small bright spot comes in the form of a decline from the internists’ time of 18.7 hours per week in 2021.

When asked if they would choose medicine again, 72% of internist respondents and 73% of all physicians said yes, with emergency medicine (65%) and dermatology (86%) representing the two extremes. A question about specialty choice showed internists to be the least likely of the 29 included specialties to follow the same path, with 61% (down from 63% in 2022) approving their initial selection, versus 97% for plastic surgeons, Medscape reported.

Doctors or AI? Lukewarm vote of confidence goes to …

Well, we’ve got some good news for the physicians out there, and we’ve got some bad news. Which do you want first? Okay, we’re mostly hearing good news, so here goes: Most people would choose a human doctor over artificial intelligence for the diagnosis and treatment of their medical conditions.

chatbot_2_web.jpg

And the bad news? In the survey we’re talking about, “most” was 53%, so not exactly a huge victory for the carbon-based life forms. Yup, about 47% of the 2,472 respondents said they would prefer an AI-based clinic over a human specialist, and that number went up if individuals were told that their primary care physicians were on board with AI, “or otherwise nudged to consider AI as good,” the research team said in a written statement released by the University of Arizona, Tucson.

They went on to add that “this signaled the significance of the human physician in guiding a patient’s decision.” So patients will still need their doctors in the future to … um … this is a bit awkward … tell them how good the AI is?

And yes, we know that ChatGPT is already doing the same thing to journalists, but could it write a medical-humor column? Not a chance. Probably can’t even tell a joke.

How do ghosts get rid of wrinkles? Boo-tox. There, let’s see ChatGPT do that.
 

Explaining the joke makes it funnier, right?

Here at LOTME headquarters, we live by one simple rule, passed down directly from the Buddha himself: “Never let a good presurgical assessment of refractory epilepsy go to waste. Also, don’t believe everything you read on the Internet.”

This human-created joke has been brought to you by the leading theory of humor, which states that comedy stems from our brain reacting to an incongruous part of reality in a positive way. These positive emotions light up our neurons in a specific fashion, and boom, comedy is achieved.

Previous studies into the science of comedy have typically used functional MRI to analyze the brain while it was gripped in the throes of a comedic reaction. Unfortunately, fMRI cannot detect the entirety of the electromagnetic spectrum generated by the brain during these moments, so observing scientists have been, quite literally, missing out on some of the joke. And that’s where a new study from France comes in.

In the study, the researchers showed a group of patients with epilepsy who were hooked up to deep brain electrodes and a high-tech neuroimaging machine – part of the aforementioned presurgical assessment – a 3-minute excerpt from a Charlie Chaplin movie and analyzed their brain activity. Why Charlie Chaplin? Simple. Slapstick is perhaps the most accessible form of comedy across cultures. We can all appreciate a man getting hit in the head with a coconut. The world’s oldest bar joke or whatever this is? Not so much.

During the funniest scenes, all study participants showed increased high-frequency gamma waves (indicating high cognitive engagement) and a decrease in low-frequency waves (indicating reduced inattention and introspection). During unfunny scenes, such as transition moments, the opposite occurred. Importantly, this inverse relationship occurred in the temporal lobe but not in other regions, supporting previous research that indicated humor was mainly processed in the temporal lobe.

The investigators suggested future research should focus on longer videos with more complex forms of comedy, such as jokes, irony, sarcasm, or reference humor. So, uh, a guy getting hit in the head with two coconuts? That’s high-brow stuff right there.
 

Hot take: Humans aren’t that special

We humans have always prided ourselves on being different from “the animals” in an exceptional way. News flash! We aren’t. We may be the apex predator, but new research shows that humans, as part of the animal kingdom, just aren’t special.

Family_outside_in_sun_web.jpg

Not special? How can they say that? Are gorillas doing open-heart surgery? Do wolverines tell jokes? At a more basic level, though, the way we operate as mammals in societies is not unique or even new. Elephants are known to mourn their deceased and to have funeral-like practices, ants invented agriculture, and we’re certainly not the only species that has figured out how to use tools.

This new research just demonstrates another way we aren’t exceptional, and that’s in our mating practices and outcomes.

“Humans appear to resemble mammals that live in monogamous partnerships and to some extent, those classified as cooperative breeders, where breeding individuals have to rely on the help of others to raise their offspring,” Monique Borgerhoff Mulder, PhD, professor emerita of anthropology at the University of California, Davis, said in a written statement.

The research team, which consisted of over 100 investigators, looked at 90 human populations based on data from over 80,000 people globally and compared the human data with 49 different nonhuman mammal species. In polygynous societies in which men take several wives, they found, women have more access to resources like food, shelter, and parenting help. Monogamy, on the other hand, “can drive significant inequalities among women,” Dr. Borgerhoff Mulder said, by promoting large differences in the number of children couples produce.

Human day-to-day behavior and child-rearing habits – one parent taking a daughter to ballet class and fixing dinner so the other parent can get to exercise class before picking up the son from soccer practice – may have us thinking that we are part of an evolved society, but really we are not much different than other mammals that hunt, forage for food, and rear and teach their children, the researchers suggested.

So, yes, humans can travel to the moon, create a vaccine for smallpox, and hit other humans with coconuts, but when it comes to simply having offspring or raising them, we’re not all that special. Get over it.

Fastest peptide north, south, east, aaaaand west of the Pecos

Bacterial infections are supposed to be simple. You get infected, you get an antibiotic to treat it. Easy. Some bacteria, though, don’t play by the rules. Those antibiotics may kill 99.9% of germs, but what about the 0.1% that gets left behind? With their fallen comrades out of the way, the accidentally drug resistant species are free to inherit the Earth.

Antibiotic resistance is thus a major concern for the medical community. Naturally, anything that prevents doctors from successfully curing sick people is a priority. Unless you’re a major pharmaceutical company that has been loath to develop new drugs that can beat antibiotic-resistant bacteria. Blah blah, time and money, blah blah, long time between development and market application, blah blah, no profit. We all know the story with pharmaceutical companies.

peptide_antibacterial_web.jpg

Research from other sources has continued, however, and Brazilian scientists recently published research involving a peptide known as plantaricin 149. This peptide, derived from the bacterium Lactobacillus plantarum, has been known for nearly 30 years to have antibacterial properties. Pln149 in its natural state, though, is not particularly efficient at bacteria-killing. Fortunately, we have science and technology on our side.

The researchers synthesized 20 analogs of Pln149, of which Pln149-PEP20 had the best results. The elegantly named compound is less than half the size of the original peptide, less toxic, and far better at killing any and all drug-resistant bacteria the researchers threw at it. How much better? Pln149-PEP20 started killing bacteria less than an hour after being introduced in lab trials.

The research is just in its early days – just because something is less toxic doesn’t necessarily mean you want to go and help yourself to it – but we can only hope that those lovely pharmaceutical companies deign to look down upon us and actually develop a drug utilizing Pln149-PEP20 to, you know, actually help sick people, instead of trying to build monopolies or avoiding paying billions in taxes. Yeah, we couldn’t keep a straight face through that last sentence either.
 

Speed healing: The wavy wound gets the swirl

Did you know that wavy wounds heal faster than straight wounds? Well, we didn’t, but apparently quite a few people did, because somebody has been trying to figure out why wavy wounds heal faster than straight ones. Do the surgeons know about this? How about you dermatologists? Wavy over straight? We’re the media. We’re supposed to report this kind of stuff. Maybe hit us with a tweet next time you do something important, or push a TikTok our way, okay?

You could be more like the investigators at Nanyang Technological University in Singapore, who figured out the why and then released a statement about it.

They created synthetic wounds – some straight, some wavy – in micropatterned hydrogel substrates that mimicked human skin. Then they used an advanced optical technique known as particle image velocimetry to measure fluid flow and learn how cells moved to close the wound gaps.

The wavy wounds “induced more complex collective cell movements, such as a swirly, vortex-like motion,” according to the written statement from NTU Singapore. In the straight wounds, cell movements paralleled the wound front, “moving in straight lines like a marching band,” they pointed out, unlike some researchers who never call us unless they need money.

Complex epithelial cell movements are better, it turns out. Over an observation period of 64 hours the NTU team found that the healing efficiency of wavy gaps – measured by the area covered by the cells over time – is nearly five times faster than straight gaps.

The complex motion “enabled cells to quickly connect with similar cells on the opposite site of the wound edge, forming a bridge and closing the wavy wound gaps faster than straight gaps,” explained lead author Xu Hongmei, a doctoral student at NTU’s School of Mechanical and Aerospace Engineering, who seems to have time to toss out a tumblr or two to keep the press informed.

As for the rest of you, would it kill you to pick up a phone once in a while? Maybe let a journalist know that you’re still alive? We have feelings too, you know, and we worry.
 

A little Jekyll, a little Hyde, and a little shop of horrors

More “Little Shop of Horrors” references are coming, so be prepared.

We begin with Triphyophyllum peltatum. This woody vine is of great interest to medical and pharmaceutical researchers because its constituents have shown promise against pancreatic cancer and leukemia cells, among others, along with the pathogens that cause malaria and other diseases. There is another side, however. T. peltatum also has a tendency to turn into a realistic Audrey II when deprived.

No, of course they’re not craving human flesh, but it does become … carnivorous in its appetite.

T. peltatum, native to the West African tropics and not found in a New York florist shop, has the unique ability to change its diet and development based on the environmental circumstances. For some unknown reason, the leaves would develop adhesive traps in the form of sticky drops that capture insect prey. The plant is notoriously hard to grow, however, so no one could study the transformation under lab conditions. Until now.

triphyophyllum_web.jpg

A group of German scientists “exposed the plant to different stress factors, including deficiencies of various nutrients, and studied how it responded to each,” said Dr. Traud Winkelmann of Leibniz University Hannover. “Only in one case were we able to observe the formation of traps: in the case of a lack of phosphorus.”

Well, there you have it: phosphorus. We need it for healthy bones and teeth, which this plant doesn’t have to worry about, unlike its Tony Award–nominated counterpart. The investigators hope that their findings could lead to “future molecular analyses that will help understand the origins of carnivory,” but we’re guessing that a certain singing alien species will be left out of that research.

Fastest peptide north, south, east, aaaaand west of the Pecos

Bacterial infections are supposed to be simple. You get infected, you get an antibiotic to treat it. Easy. Some bacteria, though, don’t play by the rules. Those antibiotics may kill 99.9% of germs, but what about the 0.1% that gets left behind? With their fallen comrades out of the way, the accidentally drug resistant species are free to inherit the Earth.

Antibiotic resistance is thus a major concern for the medical community. Naturally, anything that prevents doctors from successfully curing sick people is a priority. Unless you’re a major pharmaceutical company that has been loath to develop new drugs that can beat antibiotic-resistant bacteria. Blah blah, time and money, blah blah, long time between development and market application, blah blah, no profit. We all know the story with pharmaceutical companies.

Research from other sources has continued, however, and Brazilian scientists recently published research involving a peptide known as plantaricin 149. This peptide, derived from the bacterium Lactobacillus plantarum, has been known for nearly 30 years to have antibacterial properties. Pln149 in its natural state, though, is not particularly efficient at bacteria-killing. Fortunately, we have science and technology on our side.

The researchers synthesized 20 analogs of Pln149, of which Pln149-PEP20 had the best results. The elegantly named compound is less than half the size of the original peptide, less toxic, and far better at killing any and all drug-resistant bacteria the researchers threw at it. How much better? Pln149-PEP20 started killing bacteria less than an hour after being introduced in lab trials.

The research is just in its early days – just because something is less toxic doesn’t necessarily mean you want to go and help yourself to it – but we can only hope that those lovely pharmaceutical companies deign to look down upon us and actually develop a drug utilizing Pln149-PEP20 to, you know, actually help sick people, instead of trying to build monopolies or avoiding paying billions in taxes. Yeah, we couldn’t keep a straight face through that last sentence either.
 

Speed healing: The wavy wound gets the swirl

Did you know that wavy wounds heal faster than straight wounds? Well, we didn’t, but apparently quite a few people did, because somebody has been trying to figure out why wavy wounds heal faster than straight ones. Do the surgeons know about this? How about you dermatologists? Wavy over straight? We’re the media. We’re supposed to report this kind of stuff. Maybe hit us with a tweet next time you do something important, or push a TikTok our way, okay?

Overweight boy, infertile man?

When it comes to causes of infertility, history and science have generally focused on women. A lot of the research overlooks men, but some previous studies have suggested that male infertility contributes to about half of the cases of couple infertility. The reason for much of that male infertility, however, has been a mystery. Until now.

baby_cake_web.jpg

A group of Italian investigators looked at the declining trend in sperm counts over the past 40 years and the increase of childhood obesity. Is there a correlation? The researchers think so. Childhood obesity can be linked to multiple causes, but the researchers zeroed in on the effect that obesity has on metabolic rates and, therefore, testicular growth.

Collecting data on testicular volume, body mass index (BMI), and insulin resistance from 268 boys aged 2-18 years, the researchers discovered that those with normal weight and normal insulin levels had testicular volumes 1.5 times higher than their overweight counterparts and 1.5-2 times higher than those with hyperinsulinemia, building a case for obesity being a factor for infertility later in life.

Since low testicular volume is associated with lower sperm count and production as an adult, putting two and two together makes a compelling argument for childhood obesity being a major male infertility culprit. It also creates even more urgency for the health care industry and community decision makers to focus on childhood obesity.

It sure would be nice to be able to take one of the many risk factors for future human survival off the table. Maybe by taking something, like cake, off the table.

Fecal transplantation moves to the kitchen

Fecal microbiota transplantation is an effective way to treat Clostridioides difficile infection, but, in the end, it’s still a transplantation procedure involving a nasogastric or colorectal tube or rather large oral capsules with a demanding (30-40 capsules over 2 days) dosage. Please, Science, tell us there’s a better way.

fecal_beads_web.jpg

Science, in the form of investigators at the University of Geneva and Lausanne University Hospital in Switzerland, has spoken, and there may be a better way. Presenting fecal beads: All the bacterial goodness of donor stool without the tubal insertions or massive quantities of giant capsules.

We know you’re scoffing out there, but it’s true. All you need is a little alginate, which is a “biocompatible polysaccharide isolated from brown algae” of the Phaeophyceae family. The donor feces is microencapsulated by mixing it with the alginate, dropping that mixture into water containing calcium chloride, turning it into a gel, and then freeze-drying the gel into small (just 2 mm), solid beads.

Sounds plausible enough, but what do you do with them? “These brownish beads can be easily dispersed in a liquid or food that is pleasant to eat. They also have no taste,” senior author Eric Allémann, PhD, said in a statement released by the University of Geneva.

Pleasant to eat? No taste? So which is it? If you really want to know, watch fecal beads week on the new season of “The Great British Baking Show,” when Paul and Prue judge poop baked into crumpets, crepes, and crostatas. Yum.
 

We’re on the low-oxygen diet

Nine out of ten doctors agree: Oxygen is more important to your continued well-being than food. After all, a human can go weeks without food, but just minutes without oxygen. However, ten out of ten doctors agree that the United States has an obesity problem. They all also agree that previous research has shown soldiers who train at high altitudes lose more weight than those training at lower altitudes.

tent_hypoxic_web.jpg

So, on the one hand, we have a country full of overweight people, and on the other, we have low oxygen levels causing weight loss. The solution, then, is obvious: Stop breathing.

More specifically (and somewhat less facetiously), researchers from Louisiana have launched the Low Oxygen and Weight Status trial and are currently recruiting individuals with BMIs of 30-40 to, uh, suffocate themselves. No, no, it’s okay, it’s just when they’re sleeping.

Fine, straight face. Participants in the LOWS trial will undergo an 8-week period when they will consume a controlled weight-loss diet and spend their nights in a hypoxic sealed tent, where they will sleep in an environment with an oxygen level equivalent to 8,500 feet above sea level (roughly equivalent to Aspen, Colo.). They will be compared with people on the same diet who sleep in a normal, sea-level oxygen environment.

The study’s goal is to determine whether or not spending time in a low-oxygen environment will suppress appetite, increase energy expenditure, and improve weight loss and insulin sensitivity. Excessive weight loss in high-altitude environments isn’t a good thing for soldiers – they kind of need their muscles and body weight to do the whole soldiering thing – but it could be great for people struggling to lose those last few pounds. And it also may prove LOTME’s previous thesis: Air is not good.
