This
week, we attended the Wired Health conference in London. As always, the event
was jam-packed with innovators jostling for position in the race toward a
brighter, healthier future.
This year's Wired Health conference was as informative and insightful as ever.
Wired Health is
held yearly in London, United Kingdom. It boasts a wide array of speakers from
every corner of the health tech world, alongside forward-thinking companies who
provide a glimpse of their latest offerings.
This
year was as varied as ever, and the talks covered how technology could
intervene in issues as diverse as HIV, bereavement in children, and
cardiovascular surgery.
I
spent the majority of my time at the EY WIRED Health Access Stage, which
featured an annual showcase of start-up companies.
For
me, the over-arching theme this year was one of consolidation. I saw less focus
on newfangled technology and more emphasis on the use of recent innovations in
more efficient ways.
Rather
than designing solutions from the bottom up, it seems to be more about
capitalizing on hard-won inventions of the recent past.
We have the data — now what?
Early
on in the proceedings, Pamela Spence — the Global Life Science Leader at EY — reminded us that
we are currently knee-deep in the fourth industrial revolution. And, key to
this brave new dawn is that four letter word that promises so much: data.
Big data is here. What's the next step?
Today,
capturing data is easier than ever. There are more data available to us than we
could have dreamt of just a decade ago. We have almost unlimited processing
power at our fingertips.
The
question is, which bits do we pay attention to, who gets to share it, and what
shall we do with it?
Spence
spoke of the problems with collating this new-found swarm of numbers.
Healthcare data tend to be spread out and distributed into different silos.
If
they could be combined more efficiently and analyzed effectively, they could be
harnessed for the greater good.
She quipped that clinicians used to be supported by
data scientists but, more and more, data scientists are being supported by
clinicians.
This
is the future of health tech. However, at the moment, you get the feeling that
the data we are harnessing are nowhere near as useful as they promise to
become.
One
company bent on harnessing medicine's new-found ocean of data is Heterogeneous.
Though gene sequencing has been available for some time, Heterogeneous are
offering whole-genome sequencing at rates cheaper than could have been imagined
just a handful of years ago.
Anyone
can sign up, and, once you have had your genome sequenced, you get full
ownership of your data. You are then able to select which research projects you
would like to make your data available to.
Heterogeneous
pass your genome (anonymously) over for their study. The researchers receive
good-quality data quickly, and you receive the warm satisfaction of advancing
science passively from your armchair.
This
is not a new idea; plenty of companies offer genomic information to consumers.
However, most other companies sell these data to third parties without
informing the customer. This is completely legal and above board, but
Heterogeneous want to be part of a more open and collaborative future.
Big data vs. personalization
Although
many of the changes in healthcare are predicted to come from the rich tapestry
of data that we collect, there are also changes at the other end of the
spectrum: personalized medicine.
Bruce Levine — from the University of Pennsylvania in
Philadelphia — spoke to an enthralled audience about his work with chimeric
antigen receptors (CAR)-T cell therapy.
In
this technology, cancer patients' immune cells, or T cells,
are removed, then genetically trained to target cancer cells and reintroduced
into the patient.
Already
tested in leukemia and lymphoma, CAR-T can save lives — a single
infusion with the newly trained T cells can wipe out "kilograms"
of tumor cells. Though
the method cannot yet attack solid tumors, Levine and his colleagues are hot on
their heels.
This
intervention is very much tailored to the individual. In fact, he likened it to
an organ transplant rather than a pharmacological intervention, calling it the
"ultimate in personalized treatment." The patients' own cells are
groomed to recognize and destroy the specific cancer that they carry.
Levine's
story also provides a little insight into how quickly a medical technique can
move from the outskirts to the mainstream.
He
recalled that, just a few years back, he and the other researchers
investigating the potential of CAR-T were regarded as the "quaint"
guys in the corner. Now, they're the "hot thing," Food and Drug
Administration-approved, and, rightfully, the center of attention.
Generation App
Tech
conferences the world over are awash with smartphones and apps. I had to stop
myself from rolling my eyes when I saw the number of app-based solutions at
Wired Health this year. But I shouldn't roll my eyes.
Yes,
I was disappointed that there weren't more laser-wielding robots and
X-ray-powered rocket shoes, but this was a science conference, not a science
fiction conference (Medical News Today won't
pay for my Comic-Con ticket).
Apps
are accessible to millions of people worldwide via a few taps on a device kept
in their pocket. Their incredibly swift rise to ubiquity — let's try to
remember that Apple's App Store only opened its digital doors in July 2008 —
makes them a potentially powerful tool for the good of humanity's health, if
wielded in the right hands.
One such pair of safe hands belongs to Clinova, who
have developed an app called Caidr.
Any
health-focused conference in the U.K. is almost duty-bound to mention the
struggling British National Health Service. Although the reasons for its
troubles are largely political, finding ways to cut corners and save cash are
of particular interest.
Caidr,
which was designed by two pharmacists, helps users to "distinguish minor
ailments from a more serious illness." By answering a series of simple
questions, the app's algorithms assess whether they need to visit a doctor or
if a pharmacist could offer effective over-the-counter medications.
Some examples of Caidr screenshots.
In the United States, where waiting times to see a
doctor have sky-rocketed over recent years, this app could help to take the pressure off.
Another
company who are offering an easier, mobile-based route to healthcare is Index
Ventures, who have created an app called Kry. The app allows you to speak with a doctor directly via
your cell phone.
This
saves both the doctor's and patient's time and is significantly easier than
having to take time off work or juggle other commitments to visit the doctor's
office. It is particularly useful for people who cannot visit the doctor easily
or who live in isolated regions.
Kry
is already part of Sweden's health service, and 2 percent of all primary care appointments take place
through the app. Again, this is a good example of technology that has been
around for quite some time that is now being used in new and useful ways.
Approaching obesity from new directions
A
company called Modius have
created a wearable device that stimulates the eighth cranial nerve, helping
people to lose weight.
The Modius brain stimulation headset.
Yes,
that might sound like the science fiction I was hoping for, but it is grounded
in solid neuroscience.
As
we evolved over thousands and thousands of years, we faced starvation at every
turn.
Because
a lack of food was a constant driving force in our development, our bodies
adapted to make it very difficult for us to lose weight.
During
prehistory, keeping an extra layer of fat was an excellent way to survive. But,
now that we have access to enough food to kill ourselves, holding on to fat is
no longer such a beneficial adaptation.
The
hypothalamus, deep within the brain, helps decide when and how to lay down fat.
The Modius device is able to stimulate one of the cranial nerves that runs
fairly close to the surface of the skin, sending a current through to the
brainstem.
From
there, the stimulation moves on to the hypothalamus, reducing appetite and
encouraging the body to move toward a leaner state.
The
eighth cranial nerve is also called the auditory vestibular nerve because it
plays a role in our sense of balance. According to one of Wired Health's staff
members — who volunteered to try the brain stimulation device — it makes you
feel a little dizzy. It's not unlike the after effect of a glass of wine,
apparently.
It
can also make the user feel a little sleepy, in the same way that rocking a
baby stimulates the vestibular system and makes them woozy.
This is not a miracle cure by any stretch, but for
people who find it difficult to lose weight who are active and eating well,
this may provide a much-needed edge.
Although
the brain stimulation technology is, in this instance, cutting edge, the theory
behind it was first uncovered by NASA in 1972, although they didn't realize it
at the time. It took another 30 years to understand that stimulating the
vestibular system causes a reduction in body fat.
The
take-home message for me this year is one of regrouping. In the past decade,
there has been so much innovation that each strand of tech is still waiting to
come to fruition.
Today,
we see technology that has already been fine-tuned finally being used to
benefit global health. It's an interesting and app-heavy time for medical science.
