Welcome to Morning Medical with Dr.
0:02
Chow, your daily update on the latest in medical and health news from around the globe,
0:07
powered by artificial intelligence.
0:09
I'm your host, Dr.
0:10
Chi-Ming Chow.
0:12
In today's episode, we're diving into an intriguing topic that's been gaining a lot of
0:16
attention in the mental health community: the use of artificial intelligence chatbots as
0:21
therapists.
0:22
It's a conversation that's sparked both hope and concern, and we'll explore the good and bad
0:27
of chatbot counseling.
0:32
Imagine having a virtual cheerleader by your side, ready to listen and offer encouragement
0:36
whenever you need it.
0:38
That's how Kelly, a user of AI chatbots, described her experience.
0:44
During a particularly challenging period, Kelly found herself on a waiting list for traditional
0:49
National Health Service talking therapy to address anxiety, low self-esteem, and a
0:56
relationship breakdown.
0:58
In the meantime, she turned to chatbots on character.ai, spending up to three hours a day
1:04
exchanging messages.
1:06
For Kelly, these chatbots provided 24-hour availability and coping strategies, helping her
1:11
navigate through dark times.
1:14
The appeal of AI chatbots lies in their accessibility and non-judgmental nature.
1:20
Kelly, who comes from a family that doesn't openly discuss emotions, found it easier to
1:25
open up to a non-human entity.
1:28
This sentiment is shared by many around the world who have turned to chatbots for support.
1:33
However, it's crucial to remember that, as character.ai itself states, these are not real
1:40
people and their responses should be treated as fiction rather than professional advice.
1:46
Despite their potential benefits, AI chatbots are not without their risks.
1:52
There have been instances where chatbots have been accused of providing harmful advice.
1:57
One tragic case involves legal action against character.ai after a young user took his own
2:03
life, reportedly influenced by interactions with a chatbot.
2:07
This highlights the importance of caution when using these tools, as they can sometimes mirror
2:12
the biases present in the data they are trained on and lack the nuanced understanding of a
2:17
human therapist.
2:19
The rise in mental health referrals and long waitlists for therapy in places like England,
2:24
where nearly 426,000 referrals were made in April 2024 alone, have fueled the interest in
2:31
AI as a stopgap solution.
2:35
While some experts express concerns about biases, limitations, and security of user
2:40
information, others see potential in these tools when human help isn't readily available.
2:45
For instance, Wysa, a chatbot used by about 30 local National Health Service services, offers
2:52
self-referral for mental health support and tools like breathing exercises and guided
2:57
meditation.
2:59
However, it's important to understand that these chatbots, described as "inexperienced
3:05
therapists," rely solely on text and lack the ability to interpret body language or other
3:11
non-verbal cues that a human therapist would use.
3:15
This limitation often results in chatbots providing generic responses, which can be
3:20
frustrating for users seeking deeper engagement.
3:23
For example, Kelly noted times when the chatbot's responses felt repetitive and
3:28
unsatisfactory, especially in complex emotional situations.
3:33
Despite these limitations, some users have found chatbots to be invaluable.
3:38
Nicholas, who has autism, anxiety, and obsessive-compulsive disorder, found comfort in
3:43
using Wysa.
3:45
He appreciated the chatbot's availability during late-night hours when human support
3:49
wasn't accessible.
3:51
In moments of distress, the empathetic responses from the chatbot, such as "Nick, you
3:57
are valued.
3:58
People love you," provided a sense of human-like support.
4:02
A study from Dartmouth College suggests that chatbots can significantly reduce symptoms of
4:07
anxiety, depression, and eating disorders, though they aren't a replacement for
4:12
face-to-face care.
4:14
Concerns remain about security and privacy, with experts warning against sharing personal
4:19
or sensitive information with these platforms due to potential data misuse.
4:24
While AI chatbots cannot fully replace human therapists, they may serve as a valuable
4:29
interim tool in an overburdened mental health system.
4:33
With proper safeguards, they can offer support to those waiting for professional care, albeit
4:38
with the understanding that they are not substitutes for the nuanced and personalized
4:42
care a human therapist can provide.
4:45
As the landscape of mental health support evolves, it's essential to weigh the benefits
4:50
and limitations of AI in therapy carefully.
4:55
Let's talk about prostate cancer, a subject that's been in the spotlight recently due to
5:00
former President Joe Biden's diagnosis.
5:03
Prostate cancer is one of the most common cancers among men, and understanding the
5:08
grading system used to assess it is crucial.
5:11
Biden's diagnosis was characterized by a Gleason score of 9, which is considered
5:16
high-grade and indicates an aggressive form of the disease.
5:21
This score is part of a grading system used by doctors to determine the severity of prostate
5:27
cancer.
5:29
The Gleason score is determined by examining cancer cells under a microscope.
5:34
Pathologists assign two numbers, each ranging from one to five, based on how much the cancer
5:41
cells look like normal prostate cells.
5:44
The first number reflects the most common pattern seen in the tissue, and the second
5:48
number reflects the next most common pattern.
5:51
These two numbers are then added together to get a Gleason score, which typically ranges
5:56
from six to ten.
5:58
The higher the score, the more aggressive the cancer is likely to be.
6:03
In Biden's case, a Gleason score of 9 places it in a high-grade category, suggesting a
6:09
fast-growing cancer.
6:11
This has understandably raised concerns given that it indicates the cancer is severe and may
6:16
require more aggressive treatment.
6:18
However, it's important to note that while this form of cancer is aggressive, it appears to be
6:23
hormone-sensitive.
6:24
This means that it can potentially be managed effectively with the right treatment approach.
6:29
Hormone-sensitive prostate cancer can often be treated with medications that stop the
6:34
production of testosterone, which fuels the growth of cancer cells.
6:38
While a diagnosis of stage four cancer, which Biden has, is serious and is the most advanced
6:44
stage, there are numerous treatment options available today that can help manage the
6:48
disease and improve quality of life.
6:51
These treatments can sometimes lead to a state where there's no evidence of disease
6:55
progression, which is a hopeful prospect.
6:59
Dr.
6:59
Nicole Saphier, a medical contributor, has pointed out that while each case of prostate
7:05
cancer is unique, the fact that Biden's cancer is hormone-sensitive is a positive aspect.
7:11
She emphasized that, although it's unlikely to be completely cured, treatments can lead to
7:16
periods where the disease is not progressing.
7:20
This highlights the importance of regular screenings, as earlier detection can often lead
7:25
to better outcomes.
7:27
It's a reminder of the critical role regular screenings play in early detection and
7:32
management of prostate cancer.
7:34
Routine screenings, like the PSA blood test and digital rectal exams, can help catch the
7:40
disease before it reaches an advanced stage.
7:42
This is particularly important given that prostate cancer can often be asymptomatic in
7:47
its early stages.
7:49
As we continue to follow advancements in prostate cancer treatment, it's crucial to have
7:55
meaningful conversations about the options available and encourage regular screenings.
8:01
These steps can make a significant difference in outcomes for those diagnosed with this
8:06
common yet serious disease.
8:10
Despite his age and an ominous-sounding disease, former President Joe Biden has reason
8:15
for optimism about his aggressive prostate cancer diagnosis, announced over the weekend.
8:20
According to an announcement, the cancer is stage four, Grade Group five, and has
8:25
metastasized to bone, a disease state more commonly known as metastatic hormone-sensitive
8:30
prostate cancer.
8:32
Unspecified urinary symptoms prompted Biden, who is eighty-two, to see a doctor.
8:37
The apparent absence of other symptoms, particularly bone pain, is a potentially
8:42
favorable finding, prostate cancer experts told MedPage Today.
8:48
Dr.
8:49
Alicia Morgans from Dana-Farber Cancer Institute in Boston explained that urinary
8:55
symptoms are the most common symptoms of an enlarged prostate and of prostate cancer.
9:01
Many people ignore these symptoms until they become really bothersome, sometimes after years
9:07
of dealing with them on their own.
9:09
Importantly, prostate cancers often arise without symptoms.
9:13
In the case of President Biden, it is reassuring to hear that he does not have
9:18
symptoms from his bone metastasis, especially because we know that lack of pain is a good
9:23
prognostic factor, tending to suggest that his cancer may be more responsive to treatment.
9:30
Dr.
9:30
Stephen Freedland of Cedars-Sinai Medical Center in Los Angeles agreed, noting that the
9:36
number of bone metastases will be important, whether it is just one or a few versus many.
9:43
The final decision about treatment will depend on a combination of clinical and
9:48
cancer-specific factors, as well as the oncologist's clinical judgment and Biden's
9:53
personal preferences.
9:55
Generally, the standard initial approach to treating metastatic hormone-sensitive prostate
10:00
cancer is hormonal therapy or androgen deprivation therapy.
10:06
The usual approach is to consider androgen deprivation therapy plus an additional androgen
10:11
receptor pathway inhibitor, such as abiraterone, apalutamide, darolutamide, or
10:18
enzalutamide.
10:19
In most cases, especially for older adult patients, we would not typically add
10:25
chemotherapy in this setting, though that is also an option in addition to the androgen
10:30
deprivation therapy and androgen receptor pathway inhibitor.
10:34
Adding an androgen receptor pathway inhibitor to block residual testosterone from stimulating
10:40
a tumor growth response has been shown to improve survival.
10:44
Radiation therapy may also have a role in treating bone metastases and the prostate to
10:49
prevent further metastatic spread, according to Dr.
10:52
Morgans.
10:54
Biden's age is one of multiple factors that figure into the treatment decision process,
10:58
said Dr.
11:00
Quoc-Dien Trinh of the University of Pittsburgh School of Medicine.
11:04
The oncologist will also consider his overall health, existing medical conditions, and
11:09
personal preferences.
11:11
The goal is to balance the potential benefits of aggressive therapy with the risks of side
11:16
effects, ensuring that the chosen approach aligns with his quality-of-life expectations.
11:23
The sudden appearance of an aggressive, advanced prostate cancer is not all that
11:28
unusual, even in men who have regular medical examinations, Dr.
11:32
Morgans, Dr.
11:33
Freedland, and Dr.
11:35
Trinh agreed.
11:37
Dr.
11:38
Freedland pointed out that it definitely can happen.
11:42
Often, we see this form in people not being screened or not being screened regularly, but
11:48
even in people screened with prostate-specific antigen, sometimes the prostate-specific
11:53
antigen will rise, we do a biopsy, and find a bad cancer.
11:59
Dr.
11:59
Trinh noted that current clinical guidelines do not recommend routine screening for prostate
12:05
cancer among men Biden's age.
12:07
Regardless of the particulars of Biden's case, the outlook for men with advanced prostate
12:13
cancer has improved substantially in recent years as a result of better understanding of
12:18
the disease's biology, which has informed the development of more effective therapies.
12:24
Dr.
12:25
Morgans emphasized that in general, prostate cancer, even when metastatic, is highly
12:31
treatable.
12:32
Patients can live for many years after this kind of diagnosis, and with attention to other
12:37
health-related factors, like diet, exercise, and cardiovascular health, they can feel well
12:43
and live lives that are relatively normal.
12:46
There are genetic factors that can be associated with more aggressive disease, and
12:51
certain rare subtypes of prostate cancer that may be less responsive to treatment, but we do
12:56
not have any indication that President Biden is facing any of these concerns.
13:02
Median survival of five years or more for metastatic prostate cancer is not uncommon.
13:07
If there are only a few spots in the bone and the patient receives aggressive treatments, we
13:12
have seen some patients survive for ten or more years, said Dr.
13:15
Freedland.
13:16
Even though spread to the bone is not good, with modern treatments for prostate cancer,
13:21
outcomes can be good.
13:25
Today, we're taking a closer look at the healthcare systems of India and the United
13:29
States, drawing insights from a recent op-ed by Manav Midha, a medical doctor candidate and
13:35
researcher.
13:37
Midha's piece, titled "The Price of Survival, Paid in Advance," provides a fascinating
13:42
comparison of healthcare practices in these two countries, offering valuable lessons and
13:47
cautionary tales.
13:49
Midha begins by highlighting his experience visiting a family member in a prestigious
13:55
private hospital in Delhi, India.
13:59
Interestingly, while the hospital's facilities were nearly indistinguishable from top-tier
14:04
American hospitals, the operational practices were starkly different.
14:09
A notable policy at this hospital mandates that patients are not discharged until full payment
14:14
is received, whether from family or an insurer.
14:19
This includes not removing intravenous lines until payment is processed, which can delay
14:24
discharge, especially outside of business hours.
14:28
This policy, unfamiliar to many American patients, underscores the financial priorities
14:33
embedded in care delivery in India.
14:36
It ensures that the hospital's accounts receivable time is minimized, contrasting
14:40
sharply with the United States, where the median accounts receivable time for hospitals
14:45
ranges from forty-nine to fifty-two days.
14:48
This practice, while financially stabilizing for the hospital, can be disconcerting for
14:54
patients who are literally stuck until they pay.
14:58
Another intriguing policy involves elective surgeries.
15:01
Instead of assigning specific operating room slots, the hospital designates weeklong windows
15:06
during which patients may be called in on short notice.
15:10
This requires patients and their families to be on standby, prepared for surgery at any moment,
15:15
which presents significant challenges for those needing to take off work or otherwise adjust
15:20
their schedules.
15:22
From a health economics perspective, these policies make sense.
15:26
The hospital achieves high block utilization of operating rooms, far exceeding the fifty-five
15:32
to sixty percent typical in the United States, thus maximizing potential revenue.
15:39
However, for American patients, the overt financial priorities of the hospital might seem
15:45
unsettling.
15:46
In the U.S., financial interests in healthcare, while present, are generally more discreet.
15:53
Midha's observations also delve into cultural differences.
15:58
In India, physicians often receive a deity-like level of deference, which might contribute to
16:04
patients' willingness to accept these financial practices.
16:08
This cultural context contrasts with the American system, where financial motives in
16:14
healthcare are almost taboo to acknowledge openly.
16:17
Midha shares poignant personal stories to illustrate the financial burdens faced by
16:23
families in India.
16:24
One such story involves a friend's grandmother who needs a tumor resection and is selling gold
16:29
jewelry to afford the procedure.
16:32
Midha himself recalls his family's struggle during the COVID-19 pandemic, trying to secure
16:37
oxygen for his grandmother through black market channels, ultimately ending in tragedy when she
16:42
passed away due to complications.
16:45
These experiences highlight the stark reality that, in India, upfront payment is often a
16:51
prerequisite for receiving care, unlike in the United States, where people generally receive
16:56
medical care first, albeit with the potential burden of high medical debt afterwards.
17:02
Government hospitals in India do provide free care, but they often lack advanced specialty
17:07
coverage and have long wait times.
17:11
Ultimately, Midha's reflections lead him to appreciate aspects of the American healthcare
17:16
system, despite its flaws.
17:18
The ability to receive necessary medical care, even if followed by financial strain, is a
17:24
significant advantage.
17:26
Each healthcare system has its trade-offs, and these comparisons offer an opportunity to
17:30
reflect on what we value in medical care and how different systems address those values.
17:38
Our final topic today explores the concept of disruption in healthcare and why it often falls
17:43
short of expectations.
17:46
Dr.
17:47
John Whyte, the Chief Medical Officer of WebMD, shared his insights in a recent opinion piece,
17:52
arguing that the fixation on disruption can sometimes distract from genuine progress.
17:58
He suggests that while innovation is crucial to improving healthcare, disruption for its own
18:03
sake can be shortsighted, especially if it doesn’t consider how care is actually
18:08
delivered.
18:10
Dr.
18:11
Whyte provides a compelling example with a patient who suspected she had sleep apnea based
18:15
on data from her smartwatch.
18:17
Despite having valuable information at her fingertips, the current healthcare system
18:22
required her to undergo a formal sleep study, highlighting a disconnect between available
18:28
technology and healthcare practices.
18:31
This is a common issue where promising technologies fail to integrate smoothly into
18:37
existing clinical workflows, thus falling short of their potential.
18:42
The article emphasizes that true innovation in healthcare should evolve existing systems
18:48
thoughtfully rather than attempting to overhaul them completely.
18:53
This involves collaboration with clinicians and patients to create solutions that integrate
18:58
into current workflows and enhance patient care.
19:03
Dr.
19:03
Whyte points out that while technologies like continuous glucose monitors have revolutionized
19:09
diabetes management, they still face hurdles in integration with medical records and insurance
19:15
coverage, limiting their full impact.
19:18
Another example Dr.
19:19
Whyte discusses is the challenge faced by companies like Amazon, which have attempted to
19:25
apply their consumer-first approach to healthcare with initiatives like Amazon
19:30
Pharmacy and One Medical.
19:32
Despite their success in other industries, these projects encountered significant
19:37
obstacles due to the complex regulations and unique demands of healthcare.
19:43
This underscores the importance of designing tools that fit the realities of medical
19:48
practice, rather than imposing models that work in other fields.
19:53
Dr.
19:53
Whyte concludes that the best healthcare innovations are those that quietly improve
19:57
existing systems rather than attempting to disrupt them completely.
20:02
As healthcare continues to evolve, it’s crucial to focus on integrating new technologies in a
20:07
way that complements and enhances current practices, ensuring that these innovations
20:11
deliver real value to both providers and patients.
