A couple of years ago

2000
00:17
when I was attending the TED Conference in Long Beach,
1
2000
2000
00:19
I met Harriet.
2
4000
2000
00:21
We'd actually met online before --
3
6000
2000
00:23
not the way you're thinking.
4
8000
2000
00:25
We were actually introduced because we both knew Linda Avey,
5
10000
2000
00:27
one of the founders of the first online personal genomic companies.
6
12000
3000
00:30
And because we shared our genetic information with Linda,
7
15000
3000
00:33
she could see that Harriet and I
8
18000
2000
00:35
shared a very rare type of mitochondrial DNA --
9
20000
2000
00:37
Haplotype K1a1b1a --
10
22000
2000
00:39
which meant that we were distantly related.
11
24000
2000
00:41
We actually share the same genealogy with Ozzie the iceman.
12
26000
3000
00:44
So Ozzie, Harriet and me.
13
29000
2000
00:46
And being the current day, of course, we started our own Facebook group.
14
31000
2000
00:48
You're all welcome to join.
15
33000
2000
00:50
And when I met Harriet in person the next year at the TED Conference,
16
35000
3000
00:53
she'd gone online and ordered our own happy Haplotype T-shirts.
17
38000
2000
00:55
(Laughter)
18
40000
2000
00:57
Now why am I telling you this story,
19
42000
2000
00:59
and what does this have to do with the future of health?
20
44000
2000
01:01
Well the way I met Harriet is actually an example
21
46000
2000
01:03
of how leveraging cross-disciplinary,
22
48000
2000
01:05
exponentially-growing technologies
23
50000
2000
01:07
is affecting our future of health and wellness --
24
52000
2000
01:09
from low-cost gene analysis
25
54000
2000
01:11
to the ability to do powerful bio-informatics
26
56000
2000
01:13
to the connection of the Internet and social networking.
27
58000
3000
01:16
What I'd like to talk about today
28
61000
2000
01:18
is understanding these exponential technologies.
29
63000
2000
01:20
We often think linearly.
30
65000
2000
01:22
But if you think about it, if you have a lily pad
31
67000
2000
01:24
and it just divided every single day --
32
69000
2000
01:26
two, four, eight, 16 --
33
71000
2000
01:28
in 15 days you have 32,000.
34
73000
2000
01:30
What do you think you have in a month? We're at a billion.
35
75000
3000
01:33
So if we start to think exponentially,
36
78000
2000
01:35
we can see how this is starting to affect all the technologies around us.
37
80000
3000
01:38
And many of these technologies -- speaking as a physician and innovator --
38
83000
3000
01:41
we can really start to leverage
39
86000
2000
01:43
to impact the future of our own health and of health care,
40
88000
2000
01:45
and to address many of the major challenges that we have in health care today,
41
90000
3000
01:48
ranging from the really exponential costs
42
93000
2000
01:50
to the aging population,
43
95000
2000
01:52
the way we really don't use information very well today,
44
97000
2000
01:54
the fragmentation of care
45
99000
2000
01:56
and often the very difficult course
46
101000
2000
01:58
of adoption of innovation.
47
103000
2000
02:00
And one of the major things we can do we've talked a bit about here today
48
105000
2000
02:02
is moving the curve to the left.
49
107000
2000
02:04
We spend most of our money on the last 20 percent of life.
50
109000
2000
02:06
What if we could spend and incentivize positions
51
111000
2000
02:08
in the health care system and our own self
52
113000
2000
02:10
to move the curve to the left and improve our health,
53
115000
2000
02:12
leveraging technology as well?
54
117000
2000
02:14
Now my favorite technology, example of exponential technology,
55
119000
3000
02:17
we all have in our pocket.
56
122000
2000
02:19
So if you think about it, these are really dramatically improving.
57
124000
3000
02:22
I mean this is the iPhone 4.
58
127000
2000
02:24
Imagine what the iPhone 8 will be able to do.
59
129000
3000
02:27
Now, I've gained some insight into this.
60
132000
2000
02:29
I've been the track share
61
134000
2000
02:31
for the medicine portion of a new institution called Singularity University
62
136000
3000
02:34
based in Silicon Valley.
63
139000
2000
02:36
And we bring together every summer
64
141000
2000
02:38
about 100 very talented students from around the world.
65
143000
2000
02:40
And we look at these exponential technologies from medicine, biotech,
66
145000
2000
02:42
artificial intelligence, robotics, nanotechnology, space,
67
147000
3000
02:45
and address how can we cross-train
68
150000
2000
02:47
and leverage these to impact major unmet goals.
69
152000
2000
02:49
We also have seven-day executive programs.
70
154000
2000
02:51
And coming up next month is actually Future Med,
71
156000
3000
02:54
a program to help cross-train and leverage technologies into medicine.
72
159000
3000
02:57
Now I mentioned the phone.
73
162000
2000
02:59
These mobile phones have over 20,000 different mobile apps available --
74
164000
3000
03:02
to the point where there's one out of the U.K.
75
167000
2000
03:04
where you can pee on a little chip connected to your iPhone
76
169000
2000
03:06
and check yourself for an STD.
77
171000
2000
03:08
I don't know if I'd try that yet, but that's available.
78
173000
2000
03:10
There are all other sorts of applications,
79
175000
2000
03:12
merging your phone and diagnostics, for example --
80
177000
2000
03:14
measuring your blood glucose on your iPhone
81
179000
2000
03:16
and sending that, potentially, to your physician
82
181000
2000
03:18
so they can better understand and you can better understand
83
183000
3000
03:21
your blood sugars as a diabetic.
84
186000
2000
03:23
So let's see now how exponential technologies are taking health care.
85
188000
2000
03:25
Let's start with faster.
86
190000
2000
03:27
Well it's no secret that computers, through Moore's law,
87
192000
2000
03:29
are speeding up faster and faster.
88
194000
2000
03:31
We have the ability to do more powerful things with them.
89
196000
2000
03:33
They're really approaching, in many cases surpassing,
90
198000
2000
03:35
the ability of the human mind.
91
200000
2000
03:37
But where I think computational speed is most applicable
92
202000
3000
03:40
is in that of imaging.
93
205000
2000
03:42
The ability now to look inside the body in real time
94
207000
2000
03:44
with very high resolution is really becoming incredible.
95
209000
3000
03:47
And we're layering multiple technologies -- PET scans, CT scans
96
212000
3000
03:50
and molecular diagnostics --
97
215000
2000
03:52
to find and to seek things at different levels.
98
217000
3000
03:55
Here you're going to see the very highest resolution MRI scan done today,
99
220000
3000
03:58
reconstructed of Marc Hodosh, the curator of TEDMED.
100
223000
3000
04:01
And now we can see inside of the brain
101
226000
2000
04:03
with a resolution and ability that was never before available,
102
228000
3000
04:06
and essentially learn how to reconstruct,
103
231000
2000
04:08
and maybe even re-engineer,
104
233000
2000
04:10
or backwards engineer, the brain
105
235000
2000
04:12
so we can better understand pathology, disease and therapy.
106
237000
3000
04:15
We can look inside with real time fMRI -- in the brain at real time.
107
240000
3000
04:18
And by understanding these sorts of processes and these sorts of connections,
108
243000
3000
04:21
we're going to understand the effects of medication or meditation
109
246000
3000
04:24
and better personalize and make effective, for example,
110
249000
3000
04:27
psychoactive drugs.
111
252000
2000
04:29
The scanners for these are getting small, less expensive and more portable.
112
254000
3000
04:32
And this sort of data explosion available from these
113
257000
3000
04:35
is really almost becoming a challenge.
114
260000
2000
04:37
The scan of today takes up about 800 books, or 20 gigabytes.
115
262000
3000
04:40
The scan in a couple of years will be one terabyte, or 800,000 books.
116
265000
3000
04:43
How do you leverage that information?
117
268000
2000
04:45
Let's get personal. I won't ask who here's had a colonoscopy,
118
270000
3000
04:48
but if you're over age 50, it's time for your screening colonoscopy.
119
273000
3000
04:51
How would you like to avoid the pointy end of the stick?
120
276000
2000
04:53
Well now there's essentially a virtual colonoscopy.
121
278000
3000
04:56
Compare those two pictures, and now as a radiologist,
122
281000
2000
04:58
you can essentially fly through your patient's colon
123
283000
2000
05:00
and, augmenting that with artificial intelligence,
124
285000
2000
05:02
identify potentially, as you see here, a lesion.
125
287000
2000
05:04
Oh, we might have missed it, but using A.I. on top of radiology,
126
289000
3000
05:07
we can find lesions that were missed before.
127
292000
2000
05:09
And maybe this will encourage people to get colonoscopies
128
294000
2000
05:11
that wouldn't have otherwise.
129
296000
2000
05:13
And this is an example of this paradigm shift.
130
298000
2000
05:15
We're moving to this integration of biomedicine, information technology,
131
300000
3000
05:18
wireless and, I would say, mobile now -- this era of digital medicine.
132
303000
3000
05:21
So even my stethoscope is now digital.
133
306000
2000
05:23
And of course, there's an app for that.
134
308000
2000
05:25
We're moving, obviously, to the era of the tricorder.
135
310000
3000
05:28
So the handheld ultrasound
136
313000
2000
05:30
is basically surpassing and supplanting the stethoscope.
137
315000
3000
05:33
These are now at a price point
138
318000
2000
05:35
of -- what used to be 100,000 euros or a couple of hundred-thousand dollars --
139
320000
2000
05:37
for about 5,000 dollars, I can have the power
140
322000
2000
05:39
of a very powerful diagnostic device in my hand.
141
324000
3000
05:42
And merging this now with the advent of electronic medical records --
142
327000
3000
05:45
in the United States, we're still less than 20 percent electronic.
143
330000
3000
05:48
Here in the Netherlands, I think it's more than 80 percent.
144
333000
2000
05:50
But now that we're switching to merging medical data,
145
335000
2000
05:52
making it available electronically,
146
337000
2000
05:54
we can crowd source that information,
147
339000
2000
05:56
and now as a physician, I can access my patients' data from wherever I am
148
341000
3000
05:59
just through my mobile device.
149
344000
2000
06:01
And now, of course, we're in the era of the iPad, even the iPad 2.
150
346000
3000
06:04
And just last month the first FDA-approved application
151
349000
3000
06:07
was approved to allow radiologists
152
352000
2000
06:09
to do actual reading on these sorts of devices.
153
354000
2000
06:11
So certainly, the physicians of today, including myself,
154
356000
3000
06:14
are completely reliable on these devices.
155
359000
2000
06:16
And as you saw just about a month ago,
156
361000
2000
06:18
Watson from IBM beat the two champions in "Jeopardy."
157
363000
2000
06:20
So I want you to imagine when in a couple of years,
158
365000
2000
06:22
when we've started to apply this cloud-based information,
159
367000
3000
06:25
when we really have the A.I. physician and leverage our brains to connectivity
160
370000
3000
06:28
to make decisions and diagnostics
161
373000
2000
06:30
at a level never done.
162
375000
2000
06:32
Already today, you don't need to go to your physician in many cases.
163
377000
3000
06:35
Only for about 20 percent of actual visits do you have to lay hands on the patient.
164
380000
3000
06:38
We're now in the era of virtual visits --
165
383000
2000
06:40
from sort of the Skype-type visits you can do with American Well,
166
385000
3000
06:43
to Cisco that's developed a very complex health presence system.
167
388000
3000
06:46
The ability to interact with your health care provider is different.
168
391000
3000
06:49
And these are being augmented even by our devices again today.
169
394000
3000
06:52
Here my friend Jessica sent me a picture of her head laceration
170
397000
2000
06:54
so I can save her a trip to the emergency room -- I can do some diagnostics that way.
171
399000
3000
06:57
Or might we be able to leverage today's gaming technology,
172
402000
2000
06:59
like the Microsoft Kinect,
173
404000
2000
07:01
and hack that to enable diagnostics, for example,
174
406000
2000
07:03
in diagnosing stroke,
175
408000
2000
07:05
using simple motion detection, using hundred-dollar devices.
176
410000
3000
07:08
We can actually now visit our patients robotically --
177
413000
3000
07:11
this is the RP7; if I'm a hematologist,
178
416000
2000
07:13
visit another clinic, visit a hospital.
179
418000
3000
07:16
These will be augmented by a whole suite of tools actually in the home now.
180
421000
3000
07:19
So imagine we already have wireless scales.
181
424000
2000
07:21
You can step on the scale.
182
426000
2000
07:23
You can Tweet your weight to your friends, and they can keep you in line.
183
428000
2000
07:25
We have wireless blood pressure cuffs.
184
430000
2000
07:27
A whole gamut of these technologies are being put together.
185
432000
2000
07:29
So instead of wearing these kludgy devices, we can put on a simple patch.
186
434000
3000
07:32
This was developed by colleagues at Stanford, called the iRhythm --
187
437000
3000
07:35
completely supplants the prior technology at a much lower price point
188
440000
3000
07:38
with much more effectivity.
189
443000
2000
07:40
Now we're also in the era, today, of quantified self.
190
445000
2000
07:42
Consumers now can buy basically hundred-dollar devices,
191
447000
2000
07:44
like this little FitBit.
192
449000
2000
07:46
I can measure my steps, my caloric outtake.
193
451000
2000
07:48
I can get insight into that on a daily basis.
194
453000
2000
07:50
I can share that with my friends, with my physician.
195
455000
2000
07:52
There's watches coming out that will measure your heart rate, the Zeo sleep monitors,
196
457000
3000
07:55
a whole suite of tools that can enable you to leverage
197
460000
2000
07:57
and have insight into your own health.
198
462000
2000
07:59
And as we start to integrate this information,
199
464000
2000
08:01
we're going to know better what to do with it and how better to have insight
200
466000
3000
08:04
into our own pathologies, health and wellness.
201
469000
2000
08:06
There's even mirrors today that can pick up your pulse rate.
202
471000
3000
08:09
And I would argue, in the future, we'll have wearable devices in our clothes,
203
474000
3000
08:12
monitoring ourselves 24/7.
204
477000
2000
08:14
And just like we have the OnStar system in cars,
205
479000
2000
08:16
your red light might go on -- it won't say "check engine" though.
206
481000
2000
08:18
It's going to be "check your body" light,
207
483000
2000
08:20
and go in and get it taken care of.
208
485000
2000
08:22
Probably in a few years, you'll check into your mirror
209
487000
2000
08:24
and it's going to be diagnosing you.
210
489000
2000
08:26
(Laughter)
211
491000
2000
08:28
For those of you with kiddos at home,
212
493000
2000
08:30
how would you like to have the wireless diaper that supports your ...
213
495000
3000
08:33
too much information, I think, than you might need.
214
498000
2000
08:35
But it's going to be here.
215
500000
2000
08:37
Now we've heard a lot today about new technology and connection.
216
502000
3000
08:40
And I think some of these technologies
217
505000
2000
08:42
will enable us to be more connected with our patients,
218
507000
2000
08:44
and take more time
219
509000
2000
08:46
and actually do the important human touch elements of medicine,
220
511000
2000
08:48
as augmented by these sorts of technologies.
221
513000
2000
08:50
Now we've talked about augmenting the patient, to some degree.
222
515000
2000
08:52
How about augmenting the physician?
223
517000
2000
08:54
We're now in the era of super-enabling the surgeon
224
519000
2000
08:56
who can now go inside the body
225
521000
2000
08:58
and do things with robotic surgery, which is here today,
226
523000
2000
09:00
at a level that was not really possible
227
525000
2000
09:02
even five years ago.
228
527000
2000
09:04
Now this is being augmented with further layers of technology
229
529000
2000
09:06
like augmented reality.
230
531000
2000
09:08
So the surgeon can see inside the patient, through their lens,
231
533000
3000
09:11
where the tumor is, where the blood vessels are.
232
536000
2000
09:13
This can be integrated with decisions support.
233
538000
2000
09:15
A surgeon in New York can be helping a surgeon in Amsterdam, for example.
234
540000
3000
09:18
And we're entering an era
235
543000
2000
09:20
of really, truly scarless surgery called NOTES,
236
545000
2000
09:22
where the robotic endoscope can come out the stomach
237
547000
2000
09:24
and pull out that gallbladder
238
549000
2000
09:26
all in a scarless way and robotically.
239
551000
2000
09:28
And this is called NOTES, and this is coming --
240
553000
2000
09:30
basically scarless surgery,
241
555000
2000
09:32
as mediated by robotic surgery.
242
557000
2000
09:34
Now how about controlling other elements?
243
559000
2000
09:36
For those who have disabilities -- the paraplegic --
244
561000
2000
09:38
there's the era of brain-computer interface, or BCI,
245
563000
3000
09:41
where chips have been put on the motor cortex
246
566000
2000
09:43
of completely quadriplegic patients
247
568000
2000
09:45
and they can control a curser or a wheelchair or, eventually, a robotic arm.
248
570000
4000
09:49
And these devices are getting smaller
249
574000
2000
09:51
and going into more and more of these patients.
250
576000
2000
09:53
Still in clinical trials, but imagine when we can connect these,
251
578000
2000
09:55
for example, to the amazing bionic limb,
252
580000
2000
09:57
such as the DEKA Arm built by Dean Kamen and colleagues,
253
582000
3000
10:00
which has 17 degrees of motion and freedom
254
585000
3000
10:03
and can allow the person who's lost a limb
255
588000
2000
10:05
to have much higher levels of dexterity or control
256
590000
2000
10:07
than they've had in the past.
257
592000
2000
10:09
So we're really entering the era of wearable robotics actually.
258
594000
3000
10:12
If you haven't lost a limb -- you've had a stroke, for example --
259
597000
2000
10:14
you can wear these augmented limbs.
260
599000
2000
10:16
Or if you're a paraplegic -- like I've visited the folks at Berkley Bionics --
261
601000
3000
10:19
they've developed eLEGS.
262
604000
2000
10:21
I took this video last week. Here's a paraplegic patient actually walking
263
606000
3000
10:24
by strapping on these exoskeletons.
264
609000
2000
10:26
He's otherwise completely wheelchair-bound.
265
611000
2000
10:28
And now this is the early era of wearable robotics.
266
613000
2000
10:30
And I think by leveraging these sorts of technologies,
267
615000
2000
10:32
we're going to change the definition of disability
268
617000
2000
10:34
to in some cases be superability, or super-enabling.
269
619000
3000
10:37
This is Aimee Mullins, who lost her lower limbs as a young child,
270
622000
3000
10:40
and Hugh Herr, who's a professor at MIT
271
625000
3000
10:43
who lost his limbs in a climbing accident.
272
628000
2000
10:45
And now both of these can climb better, move faster, swim differently
273
630000
3000
10:48
with their prosthetics than us normal-abled persons.
274
633000
3000
10:51
Now how about other exponentials?
275
636000
2000
10:53
Clearly the obesity trend is exponentially going in the wrong direction,
276
638000
3000
10:56
including with huge costs.
277
641000
2000
10:58
But the trend in medicine actually is to get exponentially smaller.
278
643000
3000
11:01
So a few examples: we're now in the era
279
646000
2000
11:03
of "Fantastic Voyage," the iPill.
280
648000
2000
11:05
You can swallow this completely integrated device.
281
650000
2000
11:07
It can take pictures of your GI system,
282
652000
2000
11:09
help diagnose and treat as it moves through your GI tract.
283
654000
3000
11:12
We get into even smaller micro-robots
284
657000
2000
11:14
that will eventually autonomously move through your system again
285
659000
2000
11:16
and be able to do things that surgeons can't do
286
661000
2000
11:18
in a much less invasive manner.
287
663000
2000
11:20
Sometimes these might self-assemble in your GI system
288
665000
3000
11:23
and be augmented in that reality.
289
668000
2000
11:25
On the cardiac side, pacemakers are getting smaller
290
670000
2000
11:27
and much easier to place
291
672000
2000
11:29
so you don't need to train an interventional cardiologist to place them.
292
674000
2000
11:31
And they're going to be wirelessly telemetered again to your mobile devices
293
676000
3000
11:34
so you can go places and be monitored remotely.
294
679000
3000
11:37
These are shrinking even further.
295
682000
2000
11:39
Here's one that's in prototyping by Medtronic that's smaller than a penny.
296
684000
3000
11:42
Artificial retinas, the ability to put these arrays on the back of the eyeball
297
687000
3000
11:45
and allow the blind to see.
298
690000
2000
11:47
Again, in early trials, but moving into the future.
299
692000
2000
11:49
These are going to be game changing.
300
694000
2000
11:51
Or for those of us who are sighted,
301
696000
2000
11:53
how about having the assisted-living contact lens?
302
698000
2000
11:55
BlueTooth, WiFi available -- beams back images to your eye.
303
700000
3000
11:58
Now if you have trouble maintaining your diet,
304
703000
3000
12:01
it might help to have some extra imagery
305
706000
2000
12:03
to remind you how many calories are going to be coming at you.
306
708000
3000
12:07
How about enabling the pathologist to use their cell phone again
307
712000
2000
12:09
to see at a microscopic level
308
714000
2000
12:11
and to lumber that data back to the cloud and make better diagnostics?
309
716000
3000
12:14
In fact, the whole era of laboratory medicine
310
719000
2000
12:16
is completely changing.
311
721000
2000
12:18
We can now leverage microfluidics,
312
723000
2000
12:20
like this chip made by Steve Quake at Stanford.
313
725000
2000
12:22
Microfluidics can replace an entire lab of technicians.
314
727000
3000
12:25
Put it on a chip, enable thousands of tests to be done
315
730000
2000
12:27
at the point of care, anywhere in the world.
316
732000
2000
12:29
And this is really going to leverage technology
317
734000
2000
12:31
to the rural and the under-served
318
736000
2000
12:33
and enable what used to be thousand-dollar tests to be done at pennies
319
738000
2000
12:35
and at the point of care.
320
740000
2000
12:37
If we go down the small pathway a little bit farther,
321
742000
3000
12:40
we're entering the era of nanomedicine,
322
745000
2000
12:42
the ability to make devices super small
323
747000
2000
12:44
to the point where we can design red blood cells
324
749000
2000
12:46
or microrobots that will monitor our blood system or immune system,
325
751000
3000
12:49
or even those that might clear out the clots from our arteries.
326
754000
3000
12:52
Now how about exponentially cheaper?
327
757000
2000
12:54
Not something we usually think about in the era of medicine,
328
759000
3000
12:57
but hard disks used to be 3,400 dollars for 10 megabytes -- exponentially cheaper.
329
762000
3000
13:00
In genomics now,
330
765000
2000
13:02
the genome cost about a billion dollars
331
767000
2000
13:04
about 10 years ago when the first one came out.
332
769000
2000
13:06
We're now approaching essentially a thousand-dollar genome --
333
771000
2000
13:08
probably next year to two years, probably a hundred-dollar genome.
334
773000
2000
13:10
What are we going to do with hundred-dollar genomes?
335
775000
3000
13:13
And soon we'll have millions of these tests available.
336
778000
2000
13:15
And that's when it gets interesting, when we start to crowdsource that information.
337
780000
3000
13:18
And we enter the era of true personalized medicine --
338
783000
2000
13:20
the right drug for the right person at the right time --
339
785000
3000
13:23
instead of what we're doing today, which is the same drug for everybody --
340
788000
3000
13:26
sort of blockbuster drug medications,
341
791000
2000
13:28
medications which don't work for you, the individual.
342
793000
2000
13:30
And many, many different companies are working on leveraging these approaches.
343
795000
3000
13:33
And I'll also show you a simple example, from 23andMe again.
344
798000
2000
13:35
My data indicates that I've got about average risk
345
800000
3000
13:38
for developing macular degeneration, a kind of blindness.
346
803000
2000
13:40
But if I take that same data, upload it to deCODEme,
347
805000
3000
13:43
I can look at my risk for sample type 2 diabetes.
348
808000
2000
13:45
I'm at almost twice the risk for type 2 diabetes.
349
810000
2000
13:47
I might want to watch how much dessert I have at the lunch break for example.
350
812000
3000
13:50
It might change my behavior.
351
815000
2000
13:52
Leveraging my knowledge of my pharmacogenomics --
352
817000
2000
13:54
how my genes modulate, what my drugs do and what doses I need
353
819000
3000
13:57
are going to become increasingly important,
354
822000
2000
13:59
and once in the hands of the individual and the patient,
355
824000
2000
14:01
will make better drug dosing and selection available.
356
826000
3000
14:04
So again, it's not just genes, it's multiple details --
357
829000
3000
14:07
our habits, our environmental exposure.
358
832000
2000
14:09
When was the last time your physician asked you where you've lived?
359
834000
3000
14:12
Geomedicine: where you've lived, what you've been exposed to,
360
837000
2000
14:14
can dramatically affect your health.
361
839000
2000
14:16
We can capture that information.
362
841000
2000
14:18
So genomics, proteomics, the environment,
363
843000
2000
14:20
all this data streaming at us individually and us, as poor physicians,
364
845000
2000
14:22
how do we manage it?
365
847000
2000
14:24
Well we're now entering the era of systems medicine, or systems biology,
366
849000
3000
14:27
where we can start to integrate all of this information.
367
852000
2000
14:29
And by looking at the patterns, for example, in our blood
368
854000
3000
14:32
of 10,000 biomarkers in a single test,
369
857000
2000
14:34
we can start to look at these little patterns
370
859000
2000
14:36
and detect disease at a much earlier stage.
371
861000
2000
14:38
This has been called by Lee Hood, the father of the field,
372
863000
2000
14:40
P4 medicine.
373
865000
2000
14:42
We're going to be predictive; we're going to know what you're likely to have.
374
867000
2000
14:44
We can be preventative; that prevention can be personalized;
375
869000
3000
14:47
and more importantly, it's going to become increasingly participatory.
376
872000
2000
14:49
Through websites like Patients Like Me
377
874000
2000
14:51
or managing your data on Microsoft HealthVault or Google Health,
378
876000
3000
14:54
leveraging this together in participatory ways
379
879000
2000
14:56
is going to become increasingly important.
380
881000
2000
14:58
So I'll finish up with exponentially better.
381
883000
2000
15:00
We'd like to get therapies better and more effective.
382
885000
2000
15:02
Now today we treat high blood pressure mostly with pills.
383
887000
2000
15:04
What if we take a new device
384
889000
2000
15:06
and knock out the nerve vessels that help mediate blood pressure
385
891000
3000
15:09
and in a single therapy to cure hypertension?
386
894000
3000
15:12
This is a new device that is essentially doing that.
387
897000
2000
15:14
It should be on the market within a year or two.
388
899000
2000
15:16
How about more targeted therapies for cancer?
389
901000
2000
15:18
Right, I'm an oncologist
390
903000
2000
15:20
and I have to say most of what we give is actually poison.
391
905000
2000
15:22
We've learned at Stanford and other places
392
907000
2000
15:24
that we can discover cancer stem cells,
393
909000
2000
15:26
the ones that seem to be really responsible for disease relapse.
394
911000
3000
15:29
So if you think of cancer as a weed,
395
914000
2000
15:31
we often can whack the weed away.
396
916000
2000
15:33
It seems to shrink, but it often comes back.
397
918000
2000
15:35
So we're attacking the wrong target.
398
920000
2000
15:37
The cancer stem cells remain,
399
922000
2000
15:39
and the tumor can return months or years later.
400
924000
2000
15:41
We're now learning to identify the cancer stem cells
401
926000
3000
15:44
and identify those as targets and go for the long-term cure.
402
929000
2000
15:46
And we're entering the era of personalized oncology,
403
931000
2000
15:48
the ability to leverage all of this data together,
404
933000
2000
15:50
analyze the tumor and come up with
405
935000
2000
15:52
a real, specific cocktail for the individual patient.
406
937000
3000
15:55
Now I'll close with regenerative medicine.
407
940000
2000
15:57
So I've studied a lot about stem cells --
408
942000
2000
15:59
embryonic stem cells are particularly powerful.
409
944000
2000
16:01
We also have adult stem cells throughout our body.
410
946000
2000
16:03
We use those in my field of bone marrow transplantation.
411
948000
2000
16:05
Geron, just last year, started the first trial
412
950000
2000
16:07
using human embryonic stem cells
413
952000
2000
16:09
to treat spinal cord injuries.
414
954000
2000
16:11
Still a Phase I trial, but evolving.
415
956000
2000
16:13
We've been actually using adult stem cells
416
958000
2000
16:15
now in clinical trials for about 15 years
417
960000
2000
16:17
to approach a whole range of topics, particularly in cardiovascular disease.
418
962000
3000
16:20
We take our own bone marrow cells
419
965000
2000
16:22
and treat a patient with a heart attack,
420
967000
2000
16:24
we can see much improved heart function and actually better survival
421
969000
3000
16:27
using our own bone marrow drive cells after a heart attack.
422
972000
3000
16:30
I invented a device called the MarrowMiner,
423
975000
2000
16:32
a much less invasive way for harvesting bone marrow.
424
977000
2000
16:34
It's now been FDA approved,
425
979000
2000
16:36
and it'll hopefully be on the market in the next year or so.
426
981000
2000
16:38
Hopefully you can appreciate the device there
427
983000
2000
16:40
curving through the patient's body and removing the patient's bone marrow,
428
985000
2000
16:42
instead of with 200 punctures, with just a single puncture under local anesthesia.
429
987000
3000
16:45
But where is stem cell therapy really going?
430
990000
2000
16:47
If you think about it, every cell in your body has the same DNA
431
992000
3000
16:50
as you had when you were an embryo.
432
995000
2000
16:52
We can now reprogram your skin cells
433
997000
2000
16:54
to actually act like a pluripotent embryonic stem cell
434
999000
3000
16:57
and to utilize those potentially to treat multiple organs in that same patient --
435
1002000
3000
17:00
making your own personalized stem cell lines.
436
1005000
2000
17:02
And I think they'll be a new era of your own stem cell banking
437
1007000
3000
17:05
to have in the freezer your own cardiac cells,
438
1010000
2000
17:07
myocytes and neural cells
439
1012000
2000
17:09
to use them in the future, should you need them.
440
1014000
3000
17:12
And we're integrating this now with a whole era of cellular engineering,
441
1017000
2000
17:14
and integrating exponential technologies
442
1019000
2000
17:16
for essentially 3D organ printing --
443
1021000
2000
17:18
replacing the ink with cells
444
1023000
2000
17:20
and essentially building and reconstructing a 3D organ.
445
1025000
3000
17:23
That's where things are going to head -- still very early days.
446
1028000
2000
17:25
But I think, as integration of exponential technologies,
447
1030000
2000
17:27
this is the example.
448
1032000
2000
17:29
So in close, as you think about technology trends
449
1034000
3000
17:32
and how to impact health and medicine,
450
1037000
2000
17:34
we're entering an era of miniaturization,
451
1039000
2000
17:36
decentralization and personalization.
452
1041000
2000
17:38
And I think by pulling these things together,
453
1043000
2000
17:40
if we can start to think about how to understand and leverage these,
454
1045000
2000
17:42
we're going to empower the patient,
455
1047000
2000
17:44
enable the doctor, enhance wellness
456
1049000
2000
17:46
and begin to cure the well before they get sick.
457
1051000
3000
17:49
Because I know as a doctor, if someone comes to me with Stage I disease,
458
1054000
3000
17:52
I'm thrilled -- we can often cure them.
459
1057000
2000
17:54
But often it's too late and it's Stage III or IV cancer, for example.
460
1059000
3000
17:57
So by leveraging these technologies together,
461
1062000
2000
17:59
I think we'll enter a new era
462
1064000
2000
18:01
that I like to call Stage 0 medicine.
463
1066000
2000
18:03
And as a cancer doctor, I'm looking forward to being out of a job.
464
1068000
3000
18:06
Thanks very much.
465
1071000
2000
18:09
Host: Thank you. Thank you.
466
1074000
2000
18:11
(Applause)
467
1076000
2000
18:13
Take a bow. Take a bow.
