Hello and welcome to Morning Medical with Doctor Chow.
0:03
I'm Doctor Chi-Ming Chow, your host, bringing you the latest in medical and health news from
0:08
around the globe.
0:09
Today, we're diving into a fascinating development in the management of essential
0:13
tremor.
0:14
Let's explore a new study that highlights the potential of a wristband nerve stimulator to
0:18
improve outcomes for individuals dealing with this condition.
0:25
Recently, at the American Academy of Neurology annual meeting in San Diego, researchers
0:29
presented promising findings from the TRANQUIL trial.
0:33
This trial investigated a novel peripheral nerve stimulator worn as a wristband, which has
0:38
shown significant benefits for people with essential tremor.
0:42
This condition, which affects up to two percent of people worldwide, is one of the most common
0:47
movement disorders, primarily impacting the hands and arms.
0:53
The study focused on the Felix NeuroAI transcutaneous peripheral nerve stimulation
0:57
system, a device designed to be worn on the wrist.
1:01
Over the course of ninety days, participants using this system showed notable improvements
1:05
in their ability to perform daily activities compared to those using a sham device.
1:11
Specifically, the study reported a 6.9 point improvement in modified Activities of Daily
1:16
Living scores for those using the nerve stimulator, compared to a 2.7 point improvement
1:21
in the sham group.
1:23
The technology behind the wristband is quite innovative.
1:27
It uses artificial intelligence to continuously adjust its settings based on patient movement
1:33
data and neural recordings, all managed through a smartphone application.
1:39
This allows the device to tailor the stimulation to the individual's needs,
1:43
potentially offering a more flexible and personalized approach to managing essential
1:48
tremor.
1:49
One of the exciting aspects of this device is its potential to provide a non-surgical
1:54
alternative to existing treatments like deep brain stimulation and focused ultrasound, which
1:59
also target the brain circuits involved in tremor but require invasive procedures.
2:04
The wristband stimulates the radial, median, and ulnar nerves, potentially interrupting the
2:09
signaling that leads to tremor.
2:12
Participants in the TRANQUIL trial reported improvements in quality of life and
2:17
psychosocial scores, with nearly seventy percent of those in the nerve stimulator group
2:23
experiencing noticeable improvements in their symptoms.
2:27
Importantly, the study noted that the benefits were consistent across different ages, sexes,
2:33
and levels of tremor severity.
2:35
Most of the adverse events reported were mild skin irritations, with no serious adverse
2:41
effects observed.
2:43
As this system awaits clearance from the Food and Drug Administration, it represents a
2:47
promising step forward in the treatment of essential tremor.
2:51
By leveraging the body's own electrical signals through artificial intelligence, this wristband
2:56
could offer new hope for those struggling with this often debilitating condition.
3:01
We'll be keeping an eye on future developments as this technology progresses.
3:06
In an intriguing move, the province of Saskatchewan in Canada is launching a campaign
3:12
to recruit doctors from the United States, capitalizing on what they describe as an
3:18
"uncertain political climate" south of the border.
3:22
This digital campaign, set to launch this spring, is aptly named "Saskatchewan is
3:28
calling." The campaign aims to attract physicians, particularly in emergency medicine,
3:35
anesthesiology, and family practice, by highlighting the benefits of working in
3:39
Saskatchewan, including competitive compensation, a lower cost of living, and a
3:44
better work-life balance.
3:47
Health Minister Jeremy Cockrill emphasized that Saskatchewan offers "a new direction" for
3:53
American doctors.
3:54
He noted that the province sees an opportunity to attract these professionals to practice in
4:00
Saskatchewan, offering them aggressive incentives and attractive opportunities.
4:05
This initiative comes on the heels of an increase in inquiries from American doctors
4:09
over the past year, suggesting a growing interest in moving north for new professional
4:13
opportunities.
4:15
The campaign will target several unspecified states in the United States through digital
4:21
advertisements.
4:22
Terri Strunk, the Chief Executive Officer of the Saskatchewan Healthcare Recruitment Agency,
4:28
mentioned that Saskatchewan provides one of the quickest pathways to medical licensure for
4:33
physicians who have American Board certification.
4:36
This streamlined process could be a significant draw for American doctors considering the move.
4:43
However, the initiative has not been without its critics.
4:47
Vicki Mowat, the health critic for the New Democratic Party, argued that while recruiting
4:52
American doctors is a good idea, there are already internationally educated physicians in
4:57
Saskatchewan who are struggling to find pathways to practice.
5:02
She pointed out that the province faces long hospital and surgery wait times, suggesting
5:07
that more comprehensive efforts are needed to address these systemic issues.
5:12
This campaign is part of a broader trend in Canada, where provinces like Manitoba and
5:18
British Columbia are also looking to recruit healthcare professionals from the United States
5:23
by highlighting the stability and opportunities available north of the border.
5:29
As the political and healthcare landscape continues to evolve, it will be interesting to
5:34
see how successful these recruitment efforts are in bolstering the Canadian healthcare
5:39
system.
5:42
Heavy drinking is linked to brain lesions associated with memory and cognitive problems,
5:47
according to a new study published in the journal Neurology.
5:51
This study highlights a significant increase in the risk of brain injuries for those consuming
5:56
eight or more alcoholic drinks per week.
5:59
Researchers found that heavy drinkers had a 133 percent increased risk of developing hyaline
6:06
arteriolosclerosis, a lesion linked with memory and cognitive issues, compared to nondrinkers.
6:13
Former heavy drinkers also showed signs of sustained brain damage, though at lower rates
6:17
than current heavy drinkers.
6:19
Even moderate drinking was associated with a 60 percent higher risk of brain lesions.
6:25
The study involved a postmortem analysis of over 1,700 people with an average age of 75 at
6:33
the time of their death.
6:35
Scientists examined their brain tissue for signs of brain injury, including hyaline
6:41
arteriolosclerosis and tau tangles, which are associated with Alzheimer's disease.
6:47
Participants were divided into four groups: those who never drank, those who had up to
6:52
seven drinks weekly, those who had eight or more drinks weekly, and former heavy drinkers
6:57
who had stopped consuming alcohol.
7:00
The findings reveal a compelling link between heavy alcohol consumption and lasting impacts
7:06
on the brain.
7:08
Dr.
7:09
Leana Wen, an emergency physician and adjunct associate professor at George Washington
7:14
University, explained that the results are particularly telling because even former heavy
7:19
drinkers show evidence of sustained damage.
7:22
However, the study has its limitations, as it didn't measure the duration of alcohol
7:27
consumption or distinguish between regular and sporadic heavy drinking.
7:31
Despite these caveats, the findings align with previous research indicating alcohol's negative
7:37
effects on brain health.
7:39
To help people assess their drinking habits, it's crucial to understand what constitutes
7:44
excessive alcohol consumption.
7:46
The U.S.
7:47
Dietary Guidelines for Americans advise that women should not drink more than one drink per
7:52
day and men not more than two.
7:54
However, these guidelines are controversial, as even drinking within these limits has been
7:59
associated with elevated health risks, including cancer.
8:03
Binge drinking, defined as four or more drinks on one occasion for women and five or more for
8:09
men, also poses significant health risks.
8:12
It's important for individuals to recognize signs of problem drinking in themselves or
8:17
their loved ones.
8:19
Alcohol use disorder is the most common substance use disorder in the United States,
8:25
affecting nearly 29 million Americans aged 12 and older.
8:29
Symptoms include loss of control over drinking, difficulty fulfilling responsibilities, and
8:35
physical withdrawal symptoms.
8:38
Effective treatments are available, and no one should have to suffer alone.
8:43
The debate continues about whether it's necessary to completely abstain from alcohol or
8:48
if a healthy relationship with alcohol is possible.
8:52
While the consensus is that less alcohol is better, some people find value in sobriety
8:57
challenges like Dry January or Sober October to reassess their drinking habits.
9:02
If you drink to mask negative feelings or feel a loss of control, it's crucial to seek help.
9:08
Those wishing to cut back on alcohol should do so under medical supervision to avoid dangerous
9:14
withdrawal effects.
9:17
In an interesting update, U.S.
9:20
News & World Report has released its 2025 rankings for the "Best Medical Schools," opting
9:26
once again to categorize schools by tiers rather than using traditional ordinal rankings.
9:33
This marks the second year of utilizing a tiered system, which was initially implemented
9:38
to provide a more nuanced view of how schools perform in both research and primary care.
9:44
The rankings are based on a four-tier system, with overall scores calculated through
9:48
percentile performance against all rated schools.
9:52
Notably, the methodology does not include peer assessment or professional reputation surveys,
9:58
focusing instead on quantifiable data.
10:01
This approach reflects a shift from previous years and aligns with changes seen in other
10:06
U.S.
10:06
News rankings, such as the "Best Hospitals."
10:11
This year, 105 medical and osteopathic schools were eligible for research rankings, while 99
10:19
schools were considered for primary care rankings.
10:23
The survey included schools fully accredited by the Liaison Committee on Medical Education or
10:29
the American Osteopathic Association.
10:32
The data collected from these schools, along with third-party statistics, were used to
10:37
assign each school to a tier.
10:40
The indicators for research rankings included total research activity, research activity per
10:46
faculty, total National Institutes of Health research grants, and average grants per
10:52
faculty.
10:53
For primary care, the rankings considered the percentage of graduates practicing in primary
10:58
care specialties and entering primary care residencies.
11:02
Both types of rankings also took into account median Medical College Admission Test scores,
11:08
median undergraduate grade point averages, acceptance rates, and faculty resources.
11:14
Interestingly, schools that chose not to submit data or provided incomplete surveys were listed
11:20
as unranked.
11:21
U.S.
11:23
News emphasized the importance of transparency and encouraged schools to report data, arguing
11:28
that more data benefits everyone involved.
11:32
Despite some schools not participating, 80 percent of the top 100 schools in both research
11:37
and primary care were assessed.
11:40
This year, the Tier 1 medical schools for research include prominent institutions such as
11:45
Baylor College of Medicine, the Mayo Clinic School of Medicine, and Yale University.
11:51
For primary care, Tier 1 schools feature East Carolina University, the University of
11:57
California San Francisco, and the University of North Carolina - Chapel Hill, among others.
12:03
While the lists of highest-performing schools have some differences from last year, many
12:09
institutions have maintained their positions in the top tier.
12:13
This consistency speaks to the enduring quality and reputation of these programs, despite the
12:20
changes in ranking methodology.
12:26
Shifting gears to an intriguing development in the field of weight management, a new study has
12:31
found that a specific form of intermittent fasting may outperform traditional dieting
12:38
methods.
12:39
This research, conducted by scientists at the University of Colorado Anschutz Medical Campus,
12:45
sheds light on the potential benefits of a 4:3 intermittent fasting regimen, where individuals
12:51
alternate between days of eating freely and days of intense caloric restriction.
12:57
The study involved participants aged 18 to 60 with a body mass index ranging from 27 to 46,
13:04
which the Centers for Disease Control and Prevention classify as overweight or obese.
13:10
Over a 12-month period, participants were divided into two groups: one following a daily
13:15
caloric restriction and the other adhering to the 4:3 intermittent fasting plan.
13:21
The findings, published in the Annals of Internal Medicine, revealed that those
13:25
practicing intermittent fasting experienced a 7.6 percent reduction in body weight, compared
13:31
to a 5 percent reduction in the calorie-restricted group.
13:36
The intermittent fasting approach involved consuming only 400 to 600 calories for women
13:41
and 500 to 700 calories for men on fast days, which were not consecutive.
13:48
On the non-fast days, participants were free to eat as they pleased, though healthy choices
13:52
were encouraged.
13:54
This method, as noted by lead study co-authors Danielle Ostendorf and Victoria Catenacci,
13:59
provides a flexible yet effective weight-loss strategy.
14:03
It's worth mentioning that the study participants received comprehensive support
14:07
from registered dietitians, who guided them through their respective dietary regimens.
14:12
This support included nutrition information, behavioral change strategies, and social
14:17
support, which likely contributed to the success of both groups.
14:22
The researchers believe that the three-day fasting framework offers an optimal balance,
14:27
making it an appealing option for those seeking weight loss.
14:32
However, the study authors caution that more research is needed to confirm the safety and
14:36
efficacy of this fasting method in specific populations, such as children, older adults,
14:43
pregnant women, and individuals with chronic health conditions like diabetes or heart
14:48
disease.
14:50
They also hope to conduct long-term follow-up studies to determine which individuals are most
14:55
likely to succeed with this approach.
14:58
As we wrap up today's episode, it's clear that innovative approaches to health and wellness
15:03
continue to emerge, offering new possibilities for managing conditions like essential tremor
15:08
and obesity.
15:10
Whether it's through cutting-edge technology or novel dietary strategies, the future of
15:14
medicine is both exciting and promising.
