Lawrence Faucette, the second living person to receive a genetically modified pig heart in a transplant, has died six weeks after the experimental procedure. The University of Maryland Medical Center, where the experimental procedure had been performed, said the heart began to show signs of rejection in recent days.

“Mr. Faucette’s last wish was for us to make the most of what we have learned from our experience, so others may be guaranteed a chance for a new heart when a human organ is unavailable. He then told the team of doctors and nurses who gathered around him that he loved us. We will miss him tremendously,” Dr. Bartley Griffith, clinical director of the Cardiac Xenotransplantation Program at the University of Maryland School of Medicine, said in a statement. Griffith had performed the experimental surgery.

Honestly. He's helping pave the way so that people who have heart issues could potentially have replacements one day. Not just old dudes, but kids too.

Even if pig hearts never pan out, he got 6 more weeks with his loved ones.

[–] [email protected] 23 points 1 year ago

That's a nice metaphor.

[–] [email protected] 18 points 1 year ago (1 children)

friendly reminder that you do not need to be old to plant trees. If you have a choice to take part in a scientific study, please do. Its usually quite easy.

personally for me it was a double blind study about tapering from steroids. so a month of tapering (or not, idk, it was blind), and then a few phone calls over 6 months.

[–] [email protected] 6 points 1 year ago (1 children)

Thank you so much for participating in that. That's not an exciting thing to study, but man it's important in deciding what's the best course of treatment for patients. Your life might not have been on the line, but I still think you're a hero and I appreciate you.

[–] [email protected] 3 points 1 year ago

aww thank you so much

[–] [email protected] 11 points 1 year ago

Humanity thanks him for his sacrifice

[–] [email protected] 2 points 1 year ago (1 children)

This comment is so good I read it aloud to others. You win English today.

[–] [email protected] 2 points 1 year ago* (last edited 1 year ago)

It's a paraphrase. "Society grows great when old men plant trees whose shade they know they will never sit in." There are many versions across history. But no matter its source, it's a lovely sentiment.

My grandpa had a pig heart valve, and that thing lasted way longer than its warranty suggested. Yeah, he was told up front it would last ten years, but he got more out of it.

[–] [email protected] 77 points 1 year ago (1 children)

That's good to hear. The return policy for those things tend to be absolute garbage.

[–] [email protected] 15 points 1 year ago (1 children)

One could say he's past the point of no return.

[–] [email protected] 7 points 1 year ago

The final threshold.

[–] [email protected] 96 points 1 year ago (2 children)

A lot of people think that regular human transplants are problem free but the vast majority of them are rejected by the receiver. If it’s for a life saving procedure it can only extend the life span by so much…

[–] [email protected] 56 points 1 year ago (2 children)

My dad had a double lung transplant several months ago...we were told by his transplant team that, with transplants, rejection is a "when", not an "if". However, if caught early enough, the docs can do an incredible amount to combat rejection.

[–] [email protected] 19 points 1 year ago (8 children)

Complete layperson here but it kind of astounds me that we haven't cracked the code for this friend-or-foe identification. One would think there is some identifier or expression that is evaluated by the immune system and if we could match that we'd be golden but clearly not that simple.

[–] [email protected] 39 points 1 year ago (1 children)

We can’t even cure autoimmune diseases yet. Why the fuck has my immune system decided my own tissues are the enemy?! Such a dick move.

[–] [email protected] 6 points 1 year ago

Fucking confused white blood cells need to figure out their shit

[–] [email protected] 18 points 1 year ago (2 children)

I started reading the book Immune by the team that runs the Kurzgesagt (In a Nutshell) YouTube channel. The book is written for laypeople like us to understand, but I didn't get very far before going "holy shit this is ridiculously complicated". Honestly, just the fact that scientists understand any of this astounds me.

Rheumatologists are practicing alchemy, I'm convinced.

Years of dedication, my friend.

Surprisingly, things become simpler when there are more eyes looking at them. The more esoteric something is, the harder it will be to grasp because there are fewer resources to help you.

[–] [email protected] 8 points 1 year ago

Taking immunology right now, it's incredibly complicated. Immune cells aren't like any other cells in our bodies, they're absolutely bonkers.

[–] [email protected] 6 points 1 year ago

Biology is not as simple as 1s and 0s. We want it too be. But it's just more complex.

[–] [email protected] 6 points 1 year ago

Our bodies are just winging it. It's both beautiful and goodness and all kinds of other things but it's a bit philosophical at times.

I had ITP. Autoimmune something which means they don't know what caused it but my body stopped acknowledging that parts of my blood cell, not the entire one just a piece of it, we're not me. Of course not me gets flushed out.

But the fancy words for part of a blood cell is called a platelet if you don't have any platelets you don't clot. As you can probably pick up not being able to clot is a big problem. I was in danger of bleeding out because my body decided to take out all my platelets.

Seems like an easy problem. If a whole blood cell is me because the DNA matches and all kinds of other things, obviously one cell of me is one cell of me. But if you take one cell of me and you break it up into pieces is it still one cell of me? By definition is not it is 50% of me....

So one cell of me is obviously me and one cell of you is obviously you but what happens when we get into percents at what percent does my cell stop becoming me?

[–] [email protected] 2 points 1 year ago (2 children)

Your body has the miraculous ability to identify ANYTHING that isn’t itself: viruses, fungi, bacteria, even lots of nearly-self things like cancer.

It’s likely not a solvable problem.

[–] [email protected] 4 points 1 year ago

It’s likely not a solvable problem.

I doubt that.

[–] [email protected] 2 points 1 year ago

Fair enough.

These are very complicated processes that are difficult to interpret with such a (relatively) small number of people looking at it.

[–] [email protected] -4 points 1 year ago (1 children)

Honestly, this might sound weird, but if my body ever got to that point, I'd rather just go die in a war.

Better to go out with a bang than a wimper, imo.

[–] [email protected] 1 points 1 year ago

Lmao yeah you say that now

[–] [email protected] 10 points 1 year ago (1 children)

I’m just curious if you have data behind this?

My understanding is that rejection related deaths in solid organ transplant recipients is only ~18% and that it is actually trending downward.

[–] [email protected] 79 points 1 year ago* (last edited 1 year ago)

It's tough, these folks are often already in multiorgan failure because those organs were trying to hold up for their failing heart. So now you've got shot kidneys and lungs but a brand new heart to try and hold up those failing organs. Then you end up right back into heart failure.

[–] [email protected] 57 points 1 year ago (1 children)

I don't want people to see this as a failure.

Experiments are how we gain new information to try better the next time.

[–] [email protected] 46 points 1 year ago

Ultimately these experiments are reserved for people who are ineligible for traditional heart transplants. This person was granted an extra six weeks with their family which is easy to overlook but the family likely cherished every moment.

[–] [email protected] 23 points 1 year ago* (last edited 1 year ago) (1 children)

I guess we'll have to wait a bit to find out what killed him. The first person died due to several things like his condition and the heart had a pig virus.

[–] [email protected] 15 points 1 year ago (1 children)

The pathogen issue is a real hurdle to overcome. I am wondering if we will get viable 3D printed hearts before we get viable transplants from other species.

[–] [email protected] 3 points 1 year ago

3D-printed or stem-cell grown so they’re just new, hot-swappable copies of our own organs, minus defects thanks to CRISPR 🤯
