WEBVTT
00:00:18.240 --> 00:00:21.790
It's September 29th, and we have a lot to talk about.
00:00:22.420 --> 00:00:27.210
Most people don't really think about home accessibility until their mobility
00:00:27.210 --> 00:00:29.380
changes force that conversation.
00:00:29.930 --> 00:00:33.690
But what if you decide to take control of the unknown and design your living
00:00:33.690 --> 00:00:35.930
space for whatever the future might bring?
00:00:36.620 --> 00:00:41.460
My guest, Sarah Timmerman, joins me today to discuss the story behind what she
00:00:41.460 --> 00:00:43.930
calls the house that MS built.
00:00:44.600 --> 00:00:49.480
A home she designed from the ground up with universal accessibility in mind,
00:00:49.900 --> 00:00:55.740
from 36-inch doorways and zero-threshold transitions to built-in wall supports
00:00:55.740 --> 00:00:58.780
where future grab bars can be easily installed.
00:00:59.500 --> 00:01:03.610
Sarah's journey has led her to collaborate with architecture students,
00:01:03.840 --> 00:01:09.930
ADA specialists, and her local MS community to future-proof her independence
00:01:10.140 --> 00:01:14.370
in what I consider an amazing example of bold self-advocacy.
00:01:15.050 --> 00:01:19.250
But before we get to my conversation with Sarah, I want to invite you to download
00:01:19.250 --> 00:01:24.240
the free Real Talk MS app for your iOS or Android smartphone or tablet. it.
00:01:24.750 --> 00:01:29.600
Once you download the app, the latest episode of Real Talk MS will always be waiting for you.
00:01:30.200 --> 00:01:34.170
You'll be able to download and listen to past episodes. You'll be able to save
00:01:34.170 --> 00:01:35.450
your favorite episodes.
00:01:35.830 --> 00:01:40.340
And what I'm particularly excited about is that I'll be able to share all kinds
00:01:40.340 --> 00:01:41.660
of bonus content with you.
00:01:42.150 --> 00:01:45.350
And that content will only be available on the app.
00:01:45.870 --> 00:01:49.890
So I hope you'll take a minute to visit the Apple App Store or the Google Play
00:01:49.890 --> 00:01:53.170
Store and download the free Real Talk MS app.
00:01:53.480 --> 00:02:00.820
And you'll find those links in today's show notes or at the Real Talk MS website at realtalkms.com.
00:02:05.810 --> 00:02:10.410
If you live with progressive MS, you know how frustrating the wait-and-see game
00:02:10.410 --> 00:02:12.510
can be after trying a new treatment.
00:02:13.150 --> 00:02:17.710
It often takes months of waiting to see if symptoms ease or if progression slows
00:02:17.710 --> 00:02:24.030
down, but a newly published study offers real hope for taking the guesswork out of that process.
00:02:24.850 --> 00:02:29.470
Scientists at the Tisch Multiple Sclerosis Research Center of New York have
00:02:29.470 --> 00:02:34.870
discovered four specific biomarkers that could give doctors an early indication
00:02:35.130 --> 00:02:39.460
of whether stem cell therapy is actively helping your body heal.
00:02:40.440 --> 00:02:46.200
As a quick review, biomarkers are biological clues found in fluids like blood
00:02:46.200 --> 00:02:49.590
or the spinal fluid that surrounds your brain and spinal cord,
00:02:49.860 --> 00:02:54.420
and they function like some of the internal gauges on your car's dashboard.
00:02:54.940 --> 00:02:59.770
They can alert a doctor that a treatment is working on a cellular level long
00:02:59.770 --> 00:03:04.610
before you experience a noticeable physical change in your day-to-day symptoms.
00:03:05.230 --> 00:03:09.840
In this trial, researchers studied people with progressive MS who were receiving
00:03:09.840 --> 00:03:13.300
an innovative stem cell therapy called MSCNPs.
00:03:14.740 --> 00:03:19.230
These cells are actually made from your own bone marrow and delivered right
00:03:19.230 --> 00:03:23.880
into your spinal fluid to protect nerves and dial down autoimmune attacks.
00:03:24.750 --> 00:03:29.430
When they analyzed patients' spinal fluid before and after receiving this stem
00:03:29.430 --> 00:03:34.140
cell treatment, researchers observed four encouraging changes.
00:03:34.680 --> 00:03:37.370
First, that inflammation cooled down.
00:03:37.960 --> 00:03:41.560
Levels of a marker called CCL2
00:03:41.820 --> 00:03:46.510
dropped, showing that harmful inflammatory signals were being turned down.
00:03:47.150 --> 00:03:50.290
Then they noticed that immune cells shifted their behavior.
00:03:50.760 --> 00:03:58.190
A protein called SCF decreased, pointing to a healthier balance in immune and support cells.
00:03:58.820 --> 00:04:05.340
And two other markers, called MMP9 and CHIT1, well, they both went up,
00:04:05.650 --> 00:04:10.820
which the research team linked directly to the nervous system kicking into repair mode.
00:04:11.350 --> 00:04:16.790
Watching these four biomarkers respond gave the researchers tangible biological
00:04:16.790 --> 00:04:22.790
proof that stem cell treatments are capable of stopping harmful inflammatory activity,
00:04:23.330 --> 00:04:27.480
and shifting the central nervous system toward protection and repair.
00:04:28.270 --> 00:04:32.630
For the progressive MS community, that means we've moved a step closer to a
00:04:32.630 --> 00:04:36.550
future where your care team doesn't just hope a therapy works.
00:04:37.200 --> 00:04:42.410
They can measure the healing happening inside you weeks before you step back into the clinic.
00:04:43.110 --> 00:04:48.120
If you'd like to review the details of this study, you'll find that link in today's show notes.
00:04:52.720 --> 00:04:56.320
For years, people living with MS have asked a fundamental question.
00:04:57.000 --> 00:05:02.400
Can diet actually change what's happening at the cellular level inside the brain?
00:05:03.190 --> 00:05:07.100
While it's become clear that eating well is a fundamental pillar of wellness,
00:05:07.540 --> 00:05:14.240
tracing the exact biological pathway from a meal to a nerve cell has been difficult to pin down.
00:05:15.160 --> 00:05:19.970
Well, that connection just got a lot clearer thanks to the work of a research team in Italy.
00:05:20.740 --> 00:05:26.000
The researchers set out to uncover how a high-fat diet might contribute to the
00:05:26.000 --> 00:05:30.840
kind of nerve cell communication problems that drive MS progression.
00:05:31.590 --> 00:05:36.820
The team started by looking at real clinical data from people living with relapsing-remitting MS.
00:05:37.310 --> 00:05:42.290
They found that people with MS who were overweight or obese experienced greater
00:05:42.290 --> 00:05:48.020
levels of physical disability and had elevated levels of a chemical messenger
00:05:48.350 --> 00:05:51.740
called glutamate in their cerebrospinal fluid.
00:05:52.440 --> 00:05:56.410
So what makes glutamate important? Well, in healthy amounts,
00:05:56.410 --> 00:06:00.880
glutamate is essential for brain cells to send signals across synapses.
00:06:01.230 --> 00:06:04.150
Those are the tiny gaps where nerves communicate.
00:06:04.950 --> 00:06:06.750
But when glutamate levels spike
00:06:06.750 --> 00:06:10.760
out of control, they overstimulate nerve cells to the point of damage.
00:06:11.400 --> 00:06:16.740
Scientists call this excitotoxicity, and it essentially exhausts and damages
00:06:16.740 --> 00:06:19.080
those connections your brain relies on.
00:06:19.810 --> 00:06:24.780
To understand how a high-fat diet drives that damage, the researchers investigated
00:06:24.780 --> 00:06:28.930
the biology step-by-step in preclinical models.
00:06:29.690 --> 00:06:33.320
What they found was a direct gut-to-brain chain reaction.
00:06:34.110 --> 00:06:38.450
First, they observed that a high-fat diet disrupted the balance of bacteria
00:06:38.450 --> 00:06:44.620
in the digestive tract, significantly reducing beneficial lactobacillus species.
00:06:45.270 --> 00:06:51.670
That bacterial imbalance activated immune cells, specifically CD4-positive effector
00:06:51.670 --> 00:06:56.650
T-cells, and it weakened the blood-brain barrier, allowing those inflammatory
00:06:56.650 --> 00:06:59.020
cells to migrate straight into the brain.
00:06:59.890 --> 00:07:06.440
Inside the brain, inflammatory signals kicked off, driving up glutamate and damaging the synapses.
00:07:07.070 --> 00:07:11.830
In fact, a high-fat diet alone was enough to trigger this synaptic disruption
00:07:12.120 --> 00:07:15.630
even without any active autoimmune attacks underway.
00:07:16.640 --> 00:07:22.130
But the study didn't just highlight the problem. It showed that this pathway can be interrupted.
00:07:23.120 --> 00:07:27.510
When researchers either blocked those inflammatory T-cells from entering the
00:07:27.510 --> 00:07:34.010
brain or introduced a targeted lactobacillus-based probiotic to rebalance the
00:07:34.010 --> 00:07:36.610
gut, they saw real improvements.
00:07:37.300 --> 00:07:44.210
T-cell infiltration dropped, inflammation cooled down, and synaptic communication was protected.
00:07:44.700 --> 00:07:47.920
But now let's take a moment for a critical clarification.
00:07:48.650 --> 00:07:52.390
While the clinical link between higher body weight, glutamate levels,
00:07:52.390 --> 00:07:58.820
and disability was observed in real MS patients, the specific dietary and probiotic
00:07:58.820 --> 00:08:03.010
interventions were tested in preclinical laboratory models.
00:08:03.360 --> 00:08:05.670
They were tested in mice.
00:08:06.250 --> 00:08:10.390
That means this isn't a signal to self-treat or buy over-the-counter supplements
00:08:10.390 --> 00:08:12.380
without talking to your health care provider.
00:08:13.090 --> 00:08:17.030
What it does confirm is that the conversation around nutrition,
00:08:17.250 --> 00:08:19.980
gut health, and brain health isn't just theory.
00:08:20.560 --> 00:08:22.590
It's become measurable biology.
00:08:23.490 --> 00:08:29.220
By pinpointing exactly how dietary fats and gut bacteria influence immune traffic
00:08:29.220 --> 00:08:33.840
to the brain, this research opens the door to developing real-world targeted
00:08:33.840 --> 00:08:37.640
therapies that protect those synapses from the inside out,
00:08:38.300 --> 00:08:41.220
and that means less accumulated disability.
00:08:42.170 --> 00:08:47.180
If you'd like to review the details of this study, you'll find that link in today's show notes.
00:08:52.130 --> 00:08:55.870
If you take a disease-modifying therapy for multiple sclerosis,
00:08:56.110 --> 00:09:01.530
you know that the primary goal of almost every approved treatment today is slowing
00:09:01.530 --> 00:09:06.890
down progression, avoiding new relapses, and stopping future damage from taking hold.
00:09:07.490 --> 00:09:11.000
But the question everyone living with MS ultimately asks is,
00:09:11.510 --> 00:09:14.370
can we ever get back what's already been lost?
00:09:15.000 --> 00:09:20.470
Well, a research team at UVA Health has reported that an experimental compound
00:09:20.800 --> 00:09:27.900
called camuvudine-9 or K9 not only stopped, but actually reversed paralysis
00:09:27.900 --> 00:09:31.200
and vision loss in the laboratory mouse model of MS.
00:09:31.970 --> 00:09:36.900
The researchers discovered that a class of well-known HIV medications called
00:09:36.900 --> 00:09:40.520
NRTIs has an unexpected superpower.
00:09:41.240 --> 00:09:46.400
They block a critical cellular inflammation pathway called the inflammasome.
00:09:47.060 --> 00:09:51.710
Building on that discovery, the researchers engineered K9 as a safer,
00:09:52.050 --> 00:09:55.530
more effective derivative of these NRTIs.
00:09:55.990 --> 00:09:59.830
And in mice with the mouse version of MS, the results were striking.
00:10:00.640 --> 00:10:07.190
Mice treated with K9 regained mobility and sight, recovering considerably more
00:10:07.190 --> 00:10:12.850
physical function than mice given an already approved MS disease-modifying therapy.
00:10:13.840 --> 00:10:20.040
The drug also preserved nerve fibers and protected the fragile myelin coating that MS targets.
00:10:20.700 --> 00:10:25.580
And it stopped the rise of neurofilament light chain, which is a key biomarker
00:10:25.790 --> 00:10:28.820
that's used to measure ongoing nerve cell damage.
00:10:29.660 --> 00:10:31.420
What makes this research especially
00:10:31.420 --> 00:10:35.810
interesting is that the team didn't rely solely on the lab bench.
00:10:36.350 --> 00:10:40.680
When they analyzed real-world health insurance records covering more than 3
00:10:40.680 --> 00:10:48.960
million people, they found that people taking NRTI medications had a 41% lower risk of developing MS,
00:10:49.460 --> 00:10:56.730
and if they were already living with MS, they experienced a 36% drop in annual relapse rates.
00:10:57.590 --> 00:11:00.560
Well, now we have to take a breath as we process all of this,
00:11:00.850 --> 00:11:06.200
so I can remind you that these symptom reversal results took place in a preclinical
00:11:06.200 --> 00:11:11.320
mouse model, and there are huge differences between a mouse brain and a human brain.
00:11:11.990 --> 00:11:18.240
I'll also point out that those retrospective insurance database studies only show associations.
00:11:18.830 --> 00:11:24.210
That's not the same as a guaranteed cause and effect. So K9 remains experimental
00:11:24.210 --> 00:11:29.140
for MS, and human clinical trials are going to be essential to see if this functional
00:11:29.140 --> 00:11:33.510
recovery translates from mice with MS to people with MS.
00:11:34.080 --> 00:11:38.870
I should also mention that canine is already in human clinical trials for eye
00:11:38.870 --> 00:11:43.890
conditions like diabetic macular edema and thyroid eye disease,
00:11:44.330 --> 00:11:49.100
which means researchers aren't starting from scratch on compiling human safety data.
00:11:49.820 --> 00:11:54.610
So while patience is called for here, this research represents an important
00:11:54.610 --> 00:11:59.830
shift in focus as we see the research community moving beyond therapies that
00:11:59.830 --> 00:12:02.550
just press the pause button on MS,
00:12:03.050 --> 00:12:06.010
and instead aim for genuine restoration.
00:12:07.170 --> 00:12:11.900
If you'd like to review the details of this study, you'll find a link in today's show notes.
00:12:13.220 --> 00:12:17.170
While scientists are working hard in the lab to unlock future therapies that
00:12:17.170 --> 00:12:23.740
could one day restore lost function, living with MS means navigating the physical realities of today.
00:12:24.340 --> 00:12:27.460
And when most people think about things like home accessibility,
00:12:27.920 --> 00:12:32.610
well, that doesn't really become a serious conversation until mobility changes
00:12:32.610 --> 00:12:34.250
force that conversation.
00:12:35.060 --> 00:12:39.730
Sarah Timmerman took total control of her future by designing and building what
00:12:39.730 --> 00:12:41.950
she calls the house that MS built,
00:12:42.520 --> 00:12:47.760
a home engineered from the foundation up to future-proof her independence through
00:12:47.760 --> 00:12:51.640
smart universal design and relentless self-advocacy.
00:12:52.230 --> 00:12:54.140
In a moment, we'll meet Sarah.
00:12:58.910 --> 00:13:04.000
Sarah Timmerman lives with MS, and she spent the last year designing and preparing
00:13:04.000 --> 00:13:09.100
to build what she calls the house that MS built. Welcome to the podcast, Sarah.
00:13:09.310 --> 00:13:13.100
Welcome. Thank you so much for having me. I really appreciate it. I'm excited.
00:13:13.990 --> 00:13:17.480
So before we get to the house, and we absolutely will, tell me,
00:13:17.480 --> 00:13:22.030
when were you diagnosed and what were the changes that led to that diagnosis?
00:13:22.470 --> 00:13:26.980
Good question. I was diagnosed. I say COVID gave it to me, but I know COVID didn't.
00:13:27.280 --> 00:13:33.150
I just know that COVID piled on all the symptoms so that I could be diagnosed
00:13:33.150 --> 00:13:37.230
because looking back, we always see those onesie twosies that are like,
00:13:37.230 --> 00:13:39.130
oh, that was weird. That was weird.
00:13:39.600 --> 00:13:45.030
But then until you get multiple, sometimes you can't really be diagnosed.
00:13:45.030 --> 00:13:48.410
So I was diagnosed six years ago, right about now.
00:13:48.620 --> 00:13:52.420
Yesterday would have been my six year anniversary of going to my first doctor
00:13:52.420 --> 00:13:56.310
appointment. And so yeah, I've been living with this for six years.
00:13:57.500 --> 00:14:02.640
When I talk to people and we happen to be talking about accessibility,
00:14:02.970 --> 00:14:05.350
for most people, it comes up,
00:14:05.890 --> 00:14:12.080
in the moment when they realize they're facing some sort of a loss or some sort
00:14:12.080 --> 00:14:18.010
of progression that's affecting their mobility and they start thinking about accessibility.
00:14:18.520 --> 00:14:24.250
What motivated you to start thinking about your future accessibility at home?
00:14:24.450 --> 00:14:28.920
Well, because when I was diagnosed, some of my first symptoms were stairs.
00:14:29.320 --> 00:14:33.960
I could not trust my feet to go down a stairs.
00:14:34.480 --> 00:14:37.760
And at the time, I lived in a two-story home.
00:14:38.420 --> 00:14:42.850
And I was like, wow, okay, this isn't going to work. Thankfully,
00:14:43.220 --> 00:14:48.650
those first few days on the steroids, I was able to regain a lot of that mobility
00:14:48.650 --> 00:14:53.080
in my feet and trusting my feet. So now I do stairs fine.
00:14:53.870 --> 00:14:58.980
But what happens one day when I can't again? What happens one day when there's
00:14:58.980 --> 00:15:06.610
other kind of mobility issues that are not stairs but are just a little stair, you know?
00:15:06.880 --> 00:15:11.340
Just because it's a big stair, little stairs are just as difficult sometimes,
00:15:11.340 --> 00:15:15.590
too. So that really was like, how am I going to live here forever?
00:15:16.090 --> 00:15:20.180
I'm not. So what am I going to do? So that's really...
00:15:21.550 --> 00:15:25.240
Well, to your point, you've taken a whole lot of steps beyond just thinking
00:15:25.240 --> 00:15:27.290
about future accessibility.
00:15:27.710 --> 00:15:32.630
Did you already have a background in architecture before digging into this project?
00:15:32.920 --> 00:15:37.000
Not at all. We remodeled several of our old houses.
00:15:37.310 --> 00:15:42.090
So I know enough to know enough, but not enough to build a whole house.
00:15:42.690 --> 00:15:46.630
But yeah, I started there.
00:15:46.780 --> 00:15:50.870
Started with a piece of paper and was like, what am I going to do?
00:15:51.770 --> 00:15:52.800
And what did you do?
00:15:53.840 --> 00:15:59.070
I drew what would fit my needs and my children's needs right now.
00:15:59.470 --> 00:16:05.490
So I just got divorced. And so I knew that we needed, you know, one level.
00:16:05.810 --> 00:16:14.700
We needed three bedrooms. We needed enough places, wheelchair turnarounds if I ever get there.
00:16:15.140 --> 00:16:20.560
So I wanted to be able to get through every doorway. So every doorway in this
00:16:20.560 --> 00:16:26.470
home is 36 inches because I won't be able to retrofit anything in the future.
00:16:26.950 --> 00:16:30.220
So I needed to do it now the right way the first time.
00:16:30.480 --> 00:16:35.900
I have only two transitions in this home, the front entry and the sliding glass
00:16:35.900 --> 00:16:40.260
door. Everything else is concrete. It'll be all one level slab.
00:16:40.810 --> 00:16:46.180
All the doors are 36 inches. I've considered lever handles,
00:16:47.130 --> 00:16:52.210
future backing for future grab bars in hallways, in bathrooms,
00:16:52.670 --> 00:16:56.390
in kitchens, just areas where might need a grab bar.
00:16:56.810 --> 00:17:03.910
Let's go ahead and place that extra backing in the wall to be able to support
00:17:03.910 --> 00:17:07.100
that grab bar. Even if I don't put it in right away,
00:17:08.100 --> 00:17:12.340
I have the support in there to do that.
00:17:13.110 --> 00:17:18.320
You know, as you were describing this, the 36-inch wide doorways and,
00:17:19.110 --> 00:17:24.870
putting in the backing for future grab bars if necessary, did you have an understanding
00:17:24.870 --> 00:17:30.720
of universal design or have you been learning this in real time in this project?
00:17:31.100 --> 00:17:35.120
Yeah, learning this in real time as I go. And I've had a lot of help.
00:17:35.120 --> 00:17:40.580
So at Mizzou, there's a group called Mizzou Leaders in Construction.
00:17:40.890 --> 00:17:44.840
It's a group of students that are architecture students.
00:17:45.350 --> 00:17:48.720
So I reached out to the architecture department and was like,
00:17:49.240 --> 00:17:53.520
I need to build a house and I know I need to start with blueprints and that
00:17:53.520 --> 00:17:54.400
comes from architecture.
00:17:54.830 --> 00:18:01.500
So I just am kind of reverse engineering. I know my need and I start finding people that can help me.
00:18:01.750 --> 00:18:08.590
So the students invited me to a design charrette, and that's where we thought
00:18:08.590 --> 00:18:15.780
through all of the different layouts, all of the different ADA universal design ideas.
00:18:15.780 --> 00:18:19.130
And I wouldn't say all of them because there is so many.
00:18:19.470 --> 00:18:23.800
And also at Mizzou is an organization called the Great Plains ADA.
00:18:24.200 --> 00:18:30.840
They sent in a representative to also kind of think through some of those other
00:18:30.840 --> 00:18:33.790
things that I might not be aware of as yet
00:18:34.380 --> 00:18:41.390
and I'm part of a really great support group also through Mizzou so I also took
00:18:41.390 --> 00:18:44.130
the design to them and said all right
00:18:45.040 --> 00:18:49.600
You guys live with more mobility issues than I currently do,
00:18:50.130 --> 00:18:52.180
but I know I one day could.
00:18:52.790 --> 00:19:01.450
What do you see here that I could change that might be a burden for you in your life
00:19:02.450 --> 00:19:06.680
If you were to build this house, what would you change? And so they gave me
00:19:06.680 --> 00:19:08.560
some really great input as well.
00:19:08.920 --> 00:19:14.960
So it's just been a really wonderful journey with a lot of people that have
00:19:14.960 --> 00:19:19.370
kind of taken me under their wing and said, I like this idea.
00:19:19.370 --> 00:19:23.190
Let's help you and giving me inspiration and ideas.
00:19:23.860 --> 00:19:28.830
So when is groundbreaking and what's your projected finish date?
00:19:29.620 --> 00:19:36.350
Groundbreaking actually technically took place on my birthday this year, which was June 29th.
00:19:36.720 --> 00:19:38.150
So it's really special.
00:19:38.520 --> 00:19:41.500
And we broke ground, we put in the septic system.
00:19:41.920 --> 00:19:46.790
And next week, I have a meeting with the builder where I'm working with Anderson
00:19:46.790 --> 00:19:48.590
Homes in Columbia, Missouri.
00:19:49.210 --> 00:19:56.490
And next week, I have a meeting with them to get a groundbreaking date for the foundation.
00:19:56.850 --> 00:20:01.690
And then I'll have the whole timeline of when everything will be built.
00:20:01.690 --> 00:20:04.660
I really hope that it will be done by the end of the week.
00:20:04.660 --> 00:20:10.290
Well, it sounds like you've enlisted the assistance of most of the state of
00:20:10.290 --> 00:20:11.780
Missouri in one way or another.
00:20:13.690 --> 00:20:17.550
But I think that's great. I mean, it seems you've picked all the right collaborators.
