Around 1/3 of the adult population are affected by hypertension so it is a big

problem. Within that group around 10% of those patients have what we refer to as

resistant hypertension, which means that the blood pressure cannot be controlled

despite lifestyle modification and medications. We all have a very tiny

little organised sensor, if you wish, that sits in our neck between two large

arteries, it's called the carotid body and this is a very important organ that

modulates blood pressure by activating the sympathetic nervous system, that is

regulated by the brainstem. In patients in whom blood pressure is difficult to

control we know that these this carotid body is highly activated and all we were

trying to do is actually silence the carotid body or reduce its activity and

the way we do this is by a catheter based approach, using so-called

therapeutic ultrasound to a blade or silence the carotid body in these

patients. Medication over time and problems with the medication so we

couldn't get the blood pressure to come down. I was feeling very tired and

having to rest, breathlessness. The procedure was fine, I wouldn't say it

was painful. Once it was done, I had no side-effects and I felt much better. It

was very good that my blood pressure could come down without the medication.

I kept trying which the medication was making me sick so having this done was

really much more beneficial to me than the medication.

For Houston dialysis patients, getting treatment during the disaster means life or death - Duration: 3:40.

MILES O'BRIEN: Harvey has strained the health care system in Houston as well.

Aside from attending to the injured, there are also lifesaving treatments need by patients

with chronic diseases.

One of those is dialysis.

Tomeka Weatherspoon from Houston Public Media visited the DaVita Medical Center Dialysis

facility and filled me in a little while ago.

Tomeka, thank you for being with us.

First off, just give us an idea of how many people we're talking about here.

TOMEKA WEATHERSPOON, Houston Public Media: Well, when we arrived, there were upwards

of at least 100 people in the clinic.

When I was talking to some of the volunteers and the staff there, they were saying they

had seen hundreds, hundreds who had come in during the storm.

They were only closed for one day, and that's just because Sunday was horrific for anybody

trying to travel.

But other than that, they have been open and they have been seeing patients and getting

quite a bit of overflow.

MILES O'BRIEN: Try to give us an idea of how serious this problem is, Tomeka.

If someone misses a dialysis appointment, that's a big deal, isn't it?

TOMEKA WEATHERSPOON: It's a huge deal.

Honestly, if you miss an appointment, these treatments are regularly and scheduled for

a reason.

It's deadly.

It's potentially deadly, potentially fatal if you don't receive these treatments.

Dialysis itself is to clean out the blood.

So, certain types of liver and kidney diseases, they're unable to do that.

So it's really critical that they're able to get these treatments.

I talked to a doctor, Dr. Olivero, at the clinic.

And he was just telling me how his staff is working nonstop pretty much to administer

these treatments to all of these people.

DR.

JUAN OLIVERO, Houston Methodist Hospital: What is an inconvenience for many people,

having these types of storms, it can be a matter of life and death to these dialysis

patients.

MILES O'BRIEN: Tomeka, I know you have had chance to talk to some patients.

How are they coping?

TOMEKA WEATHERSPOON: It was really difficult, actually, to be in the clinic.

There were a lot of people waiting for this lifesaving treatment.

And just the distance people had to come to get there, it's really -- it's really, really

tough to kind of witness that.

But the patients I was able to speak with were really optimistic and really grateful

to have a clinic that was actually open when their local clinic had been closed due to

all of the flooding and just difficulty with traveling.

I talked to a patient while she was receiving treatment.

Her name was Debrah Payne, and she was just really happy to still be alive.

DEBRAH PAYNE, Dialysis Patient: I was afraid.

I just -- I didn't know what I was going to do.

And I'm sure all the other people who couldn't make it who know that they have to do this

to survive were concerned about whether they were going to make it here or not.

MILES O'BRIEN: This has to be a huge strain on the hospital staffs.

Give us sense of how they're coping.

TOMEKA WEATHERSPOON: Well, they're being really optimistic, much like some of the people,

the patients that I spoke with.

They were really passionate, and really, really cared about helping everyone that was there.

But they were still working incredibly long hours.

And, honestly, you can see them a little bit tired.

You can kind of see it in their eyes.

But they really cared about what they were doing.

They were understaffed, and, you know, had not as much resources as they probably need.

But they were just really, really passionate about helping everyone that was there.

MILES O'BRIEN: Tomeka Weatherspoon with Houston Public Media, thank you.

TOMEKA WEATHERSPOON: Thank you.

MILES O'BRIEN: A reminder that, if you're looking to give to Harvey relief efforts,

you can donate to a number of groups working on the ground.

Organizations, including the Red Cross, are accepting donations online or by phone.

Alejandro Aponte Brain Pump Probe Prototyping a Brain Treatment Pump HD 720p - Duration: 2:32.

I'm Alejandro [Aponte]. I'm from Puerto Rico.

I'm actually from the University of Puerto Rico at Mayaguez.

Even though I'm a mechanical engineering major and I've worked with

various research before developing different types of instrumentation, this is my

first time working with biological-related research.

So in our lab, we're working on a range of different types of neural implants and platforms for

diagnosing and treating neural disorders, specifically mood disorders like anxiety

and depression that affect a lot of American citizens and citizens around

the world. The critical part of this platform is we have these probes that go

into very specific neural circuits inside the brain and we want to infuse

drugs to those circuits.

So when you've made a couple weeks ago,

I know we had some part of this set up. How have you felt working with it?

Do you think you can make it better?

Definitely. Right now what I'm targeting on is how I can like control the

different aspects of the pump, trying to leave everything as static as possible.

So that'll be really important for when we want to make these smaller and

implantable, because not only do we not want movement of the needle, but we also don't

want moving of this central actuation portion.

Right so the new setup that we are looking forward to and what I'm working with the design is

instead of having like modular set-ups, so we have the electrical dock in one place

and then the tubing dock in another place separately. Where I'm looking for

was to have all of it combined so we have, we know, exactly how much initial

pressure we are putting there, and that prevents us from having bubbles

like on the long term

Okay.

which is really important.

That's actually very important for when we're building prototypes.

We want to take apart every little piece and think about

how can we make this part better and that better, and then at the end, we can put it all together.

So what we're trying to achieve here is get the set up to be as small as possible and this is

very important because the type of work that we are doing requires the pump to

being implantable, so that's our main target here.

I've worked with other research projects before and most of them were in instrumentation development.

This one is also instrumentation development which was really good. So I

was able to see the overview of the project quick and be comfortable with it.

And the cherry on top is that it is related to neural science,

which has been a topic that I've been really dying to learn.

I'm very excited to know that my work might help others'

lifestyles be better in the future.

Treatment Scores - Duration: 0:54.

Treatment Scores!

Quantifying the science of medicine behind medical treatments.

So, how does it work?

First you receive a diagnosis from your physician.

You want to know all your treatment options.

One diagnosis can have upwards of 10, 50, or even 100 treatments.

You also want to know which treatment is right for you.

Treatment Scores gives you a personalized list of possible treatments.

Each treatment on the list is given a Treatment Score.

The Treatment Score is the number produced from a statistical analysis of the medical

literature on that treatment.

It summarizes the net treatment benefit for patients who have been treated in the past.

You can share your Treatment Scores report with your doctor and discuss your options

together.
