Exactly. And as long as antibiotics are produced in factories where the left overs are just sent into the drain as well (see India, China), anything else it just a tip of the iceberg. We need true emergency antibiotics - not once that are produced the way they are produced and not once that can still be used for animals.

Do you have any sources verifying the claim that these countries dump harmful chemicals directly down the drain without any neutralizing chemistry? Tragic and stupid beyond belief if this is true. Equivalent to using one's own kitchen sink as a toilet bowl.

These countries don't. But, in competitive industrial chemical processing, the totalitarian principle applies: to quote Sir Ronald, “everything not forbidden is compulsory”.

Can you share sources, studies, be more specific ?

Interesting tidbit is Bret Weinstein's finding how all mice used for drug testing all over the world were coming from a single source and because of how they were bred, they had very long telomeres which made them much less susceptible to cancer. Somebody got a Nobel for that, the situation supposedly has improved since, but a lot of assumptions (and substances approved) are still based on research which was using th…

That’s not much?

I’m a bit confused why antibiotic resistant bacteria is so scary. My layman understanding is that antibiotics gum up the mechanism to produce the cell wall. Sure, bacteria may develop where the mechanism works a bit differently and is not affected by a certain chemical. But it seems like “disrupt cell wall production” is a huge target and we could probably disrupt it in many other ways. Humans lack a cell wall entire…

This is a very good question. The practical issues with antibiotic resistance may not be that obvious to a layperson because they tend to pop up in the hospital setting as opposed to the clinic setting that most people are familiar with. The antibiotic bottleneck centers around patients who show up to the hospital with very vague signs of infection (fever, sweats, rigors, lethargy, etc.) and are sick . Like on the ve…

Oh that's very interesting. So the problem isn't just finding a way to gum up the /single/ cell wall production process that is common across all bacteria species-- it's doing it in a way that targets some commonality between the many such mechanisms that differ per species, across all relevant species. And I suppose that between species this difference can be non trivial.

Literally 4D chess and we don't even know what the board looks like (okay it isn't chess but it is 4D).

I wonder if antidepressants protect your gut microbiome and the SSRI aspect is over stated. Would be very hard to disambiguate those two effects I suspect.

Good insight. I went through a profound burnout in 2019 after I lost my digestive health and got low serotonin due to a combination of work stress, overtraining at the gym, dehydration and a finger of booze after particularly hard days. Also food sensitivities to legumes, nightshades and almond butter, which I wasn't aware of at the time. I just learned that 25% of people who get food poisoning go on to develop IBS.…

But SSRIs reverse depression symptoms, they don't prevent it from happening in the first place. so the mechanism would have to be not just protection but some kind of restoration or rebalancing, maybe by selectively protecting some bacteria but not others. That seems a little less plausible to me.

SSRIs do lower the risk of further depressive episodes. "To conclude, this review provides evidence that continuing SSRIs for 1 year reduces risk of MDD and relapse." https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5761909/

I took SSRIs for 14 months and after I stopped this was my subjective experience as well. (And luckily only mild withdrawal/discontinuation symptoms.)

That was exactly my first thought. We could definitely throw the SSRI efficacy into doubt though by sampling CS fluid or something for actual serotonin content in cohorts who are subjectively feeling improved by SSRIs.

SSRI efficacy is already in doubt, as roughly 80% of the beneficial effects are replicated by placebos; some research has suggested that the remaining difference is due to the side effects, which make SSRIs active placebos and mess with study blinding. And, even if they are better than just an active placebo, the mechanism is probably not the effects on serotonin levels. (Discussed previously here: https://news.ycomb…

Most SSRI doesn't do much. The ones that work seems like related to dopamine metabolism. SSRI aspect is already debunked. Fluoxetine for example works and i think additionally confirmed by dramatically increased mortality since depression should decrease mortality which is why it exists.

Interesting and potentially dangerous. But as long as many millions of pigs are covered in antibiotic foam (which is just rinsed off into the drain), I'm not gonna lie sleepless over this. Resistant bacteria will cause humanity huge troubles if we don't manage to do something radical soon.

Is there any evidence that antibiotic resistance in any significant way crosses from livestock pathogens to human pathogens? I had a medical professor lecturing a couple years back saying it was basically a myth.

You mean empiric evidence as in “here is a human with an infection that is resistant to antibiotics due to livestock use”?

No, there isnt. It’s theoretical.

The answer is phages. But last time I went into the rabbit hole the TLDR was that it is not patentable so there's no money in it. And everyone needs a different phages cocktail. I sleep at night knowing that push come to shove someone will step in and mass produce machines to create personal phage cocktails.

Whenever someone says that the reason some health related thing isn't being used because it's not patentable and there's no money in it it's a pretty sure signal they don't know what they're talking about. Therapy methods, manufacturing methods, etc. are all patentable. As an example here is a patent that was granted around methods for selecting bacteriophages against specific bacteria [1]. If you search patent recor…

Yes, I don't know what I'm talking about. As I said I went into a rabbit hole and provided a TLDR.

But do these guys know what they're talking about?

https://phage.directory/capsid/phage-patentability

You may have heard through the grapevine that “phages can’t be patented”, and yet, several phage patents exist, and biotech and pharma are starting to invest in phage-based therapeutics. What’s the deal? [...] However, the patentability of phage therapies has been called into question. Several patents in the same category as phages have actually failed to hold up in court. This suggests that even if companies can find ways to successfully file phage patents, these patents may end up being worthless.

So phages may need protection in other ways.
