Okay.
Well, we're actually talking about food allergies
and if you have friends with kids.
If you ever tried to send her to school with a cake,
you realize that food allergies are just sky rocketing.
Children can't take peanut butter
and jelly anymore, right? They can't, they can't,
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 Gif was queen,
you know what I mean? Exactly.
It's really increased.
It's really has, right?
And that's not just me being old
and cranky about. Not at all.
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 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, that's huge. Yeah, this is big.
That's one of the most common childhood allergies.
It involves giving minute particles of peanuts.
So it's coming in this pull apart capsule here,
you see it here.
There's peanut powder in there.
You can add it to semi-solid food like Apple sauce.
And you slowly introduce this in minute amounts
to your child.
Have to be very clear.
This is done under the supervision of an allergist.
An allergist specifically.
Specifically, right.
Not at home, but this is actually going to,
it's not gonna 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
or goes to a restaurant.
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 doctor (audience clapping).
We're gonna 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. Working and waiting.
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
and education,
but now we're actually able to 3D print organs,
human organs made out of human cells.
So I wanna show you a graphic here.
This is a cell. Isn't that
incredible?
Right, so the ink that's being used--
Think of how many lives could be saved
with this technology? Exactly.
Yeah.
It's incredible.
It's huge.
And so you're using human cells as ink in this printer.
See here, this type of cell, the 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.
They're going to print.
Print.
My God.
Right, I know it's unbelievable, mind blowing.
It's going to print--
Print STEM cells that make a heart.
Right.
And then this actual model, this heart,
which is made out of cells is put into a bio-reactor.
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.
And we actually--
I just literally everywhere
and I'm almost bursting into tears.
I have to tell you.
It is.
It's gonna help so many people.
Oh, my God, this is so incredible.
And here we actually have,
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 to be able to print one out of human cells
is just unbelievable.
It's so exciting.
It is.
It's really exciting. (audience clapping)
What an exciting time to be in medicine.
I know, I agree.
I agree. (audience clapping)
Is there any sort of guess as to how far off this is?
If we got a heartbeat and I know
it's tiny. Heartbeat.
It's small.
I think it's probably the next few years
that we're gonna see this.
Yeah.
It's just incredible-- which is mind boggling.
To be to be alive right now
in a time that's such great progress.
I agree, I agree.
Oh, that's weird I just touched her heart.
(laughs)
