We're going to talk now about 3D printing,
and this is amazing because organ donation,
this is someplace in an area of medicine
we really need innovation.
If you think about all those people waiting for organs,
and some of them don't make it, unfortunately.
So now we have this concept of 3D printing.
I have one here, this is made out of plastic,
and this is layer by layer the human heart, a model of it.
This is something that's used for medical students
in education, but now
we're actually able to 3D print organs,
human organs, made out of human cells.
So I want to show you a graphic here.
Isn't that incredible!?
Right, so the ink...
Think of how many lives
could be saved with this technology?
Yeah It's incredible.
It's huge, It's huge.
And so you're using human cells as ink in this printer.
You see here, this type of cell, this stem cell,
it can grow into almost any type of tissue or organ.
In this case they're growing it into a heart cell,
and then they're making this ink out of these heart cells
Layer by layer.
Layer by layer they're going to...
The machine prints.
I know, it's unbelievable, mind blowing.
It's going print...
Prints stem cells... make a heart
that make a heart.
Right, and then this actual model, this heart,
which is made out of cells is put into a bioreactor,
it's surrounded by fluids that actually make it grow
into the heart tissue.
Now, this hasn't been grown
into a life-size functioning heart right now,
but, in Israel they have actually made
a smaller version of it.
And you can see here with all these chemicals
and everything helping it grow into a beating heart.
They've actually had a heartbeat, not life-size yet
but still, it's an amazing technology.
I actually...
have chills literally everywhere
I know
I'm almost bursting into tears, I have to tell you
This is going to help so many people
Oh my God, this is, this is so incredible.
And here we actually had,
this is something that's being done now.
Heart valves, 3D printed heart valves.
My Father-in-law had a heart valve replaced.
Yeah, exactly.
It's a very common operation as we get older, but, you know,
to be able to print one out of human cells
is just, unbelievable.
It's so exciting! It is, it's really exciting.
_ What an exciting time to be in medicine.
I know, I agree, I agree.
Now how far...is there any sort of guess
as to how far off this is?
If we got a heartbeat and I know it's...
Heartbeat, it's small...
I think it's probably in the next few years
that we're going to see this.
It's just incredible to be alive right now in a time
with such great progress.
I agree, I agree
Ooh that's weird, I just touched her heart.
Okay, well, we're actually talking about food allergies
and if you have friends with kids,
If you've ever tried to send them to school with a cake,
you realize that, food allergies are just skyrocketing...
Children just can't take peanut butter
and milk anymore, right?
They can't, and actually it's over doubled
in the last 20 years,
the incidence of allergies in children.
I was going to say, because when I was a child,
everybody ate peanut butter and jelly,
Totally!
Skippy was king and Jif was queen.
Exactly,
it's really increased.
It really has, right?
And that's not just me being old and creaky about it.
Not at all.
We really are much more allergic today than we were.
Much more, we have 8 million children in this country
that are allergic to some kind of food.
Why is it increasing?
Not a 100% clear,
but there are theories that we've sort of over sanitized our
kids and given them antibiotics
disrupted actually the healthy bacteria in our guts,
which then disrupt our immune system, our reaction.
So what's going on, is your body is going to release
histamine and other chemicals, which then, can cause,
and here you see the yellow is the allergy particles
triggering this burst of histamine, that can actually cause
anaphylaxis where your throat can swell up.
You see it swelling up here, to the point where you may not
be able to breathe.
This could be life threatening.
So up until now, the only advice was well,
avoid whatever triggers your allergies and carry an EpiPen.
But now, earlier this year,
there was a breakthrough because the FDA approved
the first treatment for peanut allergy,
which actually involves...
Wow!
Yeah, that's big.
That's one of the most common childhood allergies.
It involves giving minute particles of peanuts,
so it's coming in this cap, pull apart capsule here.
You see it here, there's peanut powder in there.
You can add it to salt, semi-solid food like apple sauce.
And you slowly introduce this in minute amounts
to your child, have to be very clear,
this has done under the supervision of an allergist.
Allergist is specifically right, not at home,
but this is actually going to,
it's not going to cure an allergy,
but it could help prevent one of those
accidental exposure, severe reactions.
Right, you don't have to be frightened
every time your child goes to a birthday party.
And maybe gets a little exposure, right.
And then of course, why are the cupcakes here?
So baked goods is another strategy now,
cause some kids are allergic to the raw milk
or dairy, or eggs, but they're not allergic
when they're in baked goods.
So again, under supervision of a doctor, an allergist,
you can try introducing baked goods, small amounts.
so they build up their tolerance.
Such great news, so fascinating.
