  I am your host, Dr.
• 0:10
  Chi-Ming Chow.
• 0:11
  Thank you for joining me today as we delve into some intriguing developments from the world of
• 0:15
  medicine and health.
• 0:20
  Today, we're starting with a fascinating piece of news on artificial intelligence chatbots and
• 0:27
  their performance on cognitive tests.
• 0:28
  It's an area that's sparking a lot of interest and debate.
• 0:32
  A recent study, published in The BMJ, explored how these chatbots, specifically large language
• 0:38
  models, fare on a standard cognitive assessment known as the Montreal Cognitive Assessment, or
• 0:44
  MoCA.
• 0:46
  This assessment is widely used to detect cognitive dysfunction and early signs of
• 0:51
  dementia.
• 0:53
  It evaluates various cognitive domains including attention, memory, language,
• 0:58
  visuospatial skills, and executive function.
• 1:01
  Generally, a score of 26 to 30 points is considered normal cognition, while scores of 25
• 1:09
  or less indicate cognitive impairment.
• 1:12
  In this study, researchers administered the MoCA to several prominent chatbots: ChatGPT
• 1:18
  versions 4 and 4o, Claude 3.5, and Gemini versions 1 and 1.5.
• 1:26
  Interestingly, only ChatGPT 4o managed to score within the normal cognition range, achieving 26
• 1:33
  points.
• 1:35
  Most other chatbots, including ChatGPT 4 and Claude 3.5, scored 25 points, showing signs of
• 1:43
  mild cognitive impairment.
• 1:45
  Meanwhile, Gemini 1.0 lagged further behind with just 16 points.
• 1:52
  The study highlighted that these large language models struggled primarily with tasks involving
• 1:58
  visuospatial skills and executive functions.
• 2:00
  For instance, they had difficulties with the trail-making task and the clock-drawing test,
• 2:06
  which are crucial for evaluating these cognitive areas.
• 2:09
  A particularly amusing outcome was the Gemini 1.5's attempt at the clock-drawing task, which
• 2:15
  resulted in an avocado-shaped clock, a shape sometimes linked to cognitive issues in humans.
• 2:22
  However, the chatbots performed relatively well in areas like language, naming, and attention,
• 2:28
  which are more aligned with their text-based capabilities.
• 2:32
  These findings underscore a distinct limitation of chatbots: while they're adept at handling
• 2:37
  text and language-related tasks, they fall short when it comes to tasks that require
• 2:42
  visual abstraction and executive function, areas where the human brain excels.
• 2:48
  Dr.
• 2:49
  Roy Dayan from Hadassah Hebrew University Medical Center, who led the study, pointed out
• 2:54
  that while the study was conducted with a hint of humor, it raises important questions about
• 2:59
  the role of artificial intelligence in clinical settings.
• 3:03
  He emphasized that the initial part of any physical examination involves gaining a general
• 3:09
  impression from interacting with a patient, which relies heavily on visual abstraction
• 3:15
  skills.
• 3:17
  This is a domain where current AI chatbots show significant weaknesses.
• 3:23
  The findings also bring to light the philosophical debate around AI, reminiscent of
• 3:28
  the 'Chinese Room' argument by philosopher John Searle.
• 3:32
  This thought experiment questions whether computers, despite their ability to process
• 3:37
  information, truly understand or possess consciousness.
• 3:41
  In conclusion, while artificial intelligence continues to advance and outperform humans in
• 3:47
  certain standardized tests, this study serves as a reminder of the limitations of current
• 3:54
  technology in replicating the complex cognitive functions of the human brain.
• 4:00
  As we continue to integrate AI into healthcare, it's crucial to be aware of these boundaries
• 4:05
  and ensure that technology supplements rather than replaces the nuanced skills of human
• 4:11
  clinicians.
• 4:14
  Today, we're diving into a pressing concern for this winter season that's been dubbed the
• 4:20
  "quad-demic," involving the simultaneous spread of flu, COVID-19, respiratory syncytial virus,
• 4:27
  or RSV, and norovirus.
• 4:30
  Public health experts are urging everyone to take precautions as these four infectious
• 4:35
  diseases circulate widely.
• 4:38
  While the term "quad-demic" might sound alarming, it's essentially a reflection of the
• 4:44
  typical respiratory virus season, albeit with a few more players in the mix.
• 4:50
  Dr.
• 4:50
  Robert Hopkins Jr., the medical director of the National Foundation for Infectious Diseases,
• 4:55
  emphasizes the importance of vaccinations as a key preventive measure.
• 4:59
  He advises everyone aged six months and older to get vaccinated against COVID-19 and the flu.
• 5:05
  There's also an RSV vaccine available for adults aged 75 and older, those between 60 to
• 5:11
  74 with certain chronic conditions, and expectant parents in late pregnancy.
• 5:17
  "We have tools, we just have to use them," Hopkins says, underscoring the importance of
• 5:23
  staying updated with vaccinations.
• 5:26
  Dr.
• 5:26
  William Schaffner from Vanderbilt University Medical Center also highlights this season as a
• 5:32
  crucial time for respiratory virus vaccinations.
• 5:36
  He echoes Benjamin Franklin's famous adage, "An ounce of prevention is worth a pound of cure,"
• 5:43
  to stress the importance of immunizations in preventing serious illness.
• 5:48
  But what about norovirus, often referred to as the "winter vomiting disease"?
• 5:53
  Unfortunately, there's no vaccine for norovirus, making hand hygiene paramount.
• 5:59
  Dr.
• 5:59
  Schaffner advises using plenty of soap and water, as alcohol-based hand sanitizers are not
• 6:05
  effective against this highly contagious virus.
• 6:08
  Norovirus can easily spread through contact with contaminated surfaces and then touching
• 6:14
  your nose or mouth.
• 6:16
  The same public health measures that were pivotal during the early days of COVID-19
• 6:21
  remain relevant.
• 6:22
  Dr.
• 6:23
  Hopkins suggests covering coughs with your sleeve or a handkerchief, avoiding people who
• 6:27
  are sick, and staying home when you feel ill.
• 6:30
  It's also important to consult healthcare professionals about testing and symptomatic
• 6:35
  treatments if you're unwell.
• 6:37
  In addition to vaccinations and hygiene, maintaining a healthy lifestyle is vital.
• 6:42
  Dr.
• 6:42
  Hopkins advises staying active, especially with outdoor activities, and maintaining a balanced
• 6:48
  diet and adequate fluid intake.
• 6:51
  If you're at higher risk, it might be wise to avoid crowded places where these viruses can
• 6:56
  easily spread.
• 6:58
  Looking at the current spread, flu activity is elevated across most of the United States,
• 7:04
  except in a few regions like Colorado and the Dakotas, where the levels remain normal.
• 7:09
  The A (H3) strain of influenza is predominant, and vaccination rates are disappointingly low.
• 7:16
  As of early December, only about 40.8% of adults and children have been vaccinated
• 7:21
  against the flu.
• 7:22
  COVID-19, now considered endemic, continues to pose risks, especially for the unvaccinated.
• 7:30
  Uptake of the latest COVID-19 vaccine is still below expectations, with only around 21% of
• 7:37
  adults having received it.
• 7:40
  The CDC recommends that everyone aged six months and older get the vaccine, even if
• 7:45
  they've had previous infections or vaccinations.
• 7:49
  RSV, while not as commonly discussed, poses significant risks, particularly to older
• 7:55
  adults.
• 7:56
  The newly available RSV vaccines have seen slow uptake, with less than half of those aged 75
• 8:03
  and older vaccinated.
• 8:04
  However, the test positivity rates for RSV are decreasing compared to last year, which is
• 8:10
  somewhat reassuring.
• 8:12
  Norovirus infections have been on the rise since the fall, with test positivity reaching a
• 8:17
  seasonal high.
• 8:18
  While the United States hasn't experienced outbreaks on the scale seen in the United
• 8:23
  Kingdom, the potential for spread during holiday gatherings is a concern.
• 8:27
  Dr.
• 8:28
  Schaffner warns that holiday travel and social events create optimal conditions for these
• 8:33
  viruses to transmit from person to person.
• 8:38
  Today, we're turning our attention to a significant study that highlights potential
• 8:42
  risks associated with a common pain reliever, acetaminophen, especially for individuals over
• 8:47
  the age of 65.
• 8:49
  This research, published in Arthritis Care & Research, analyzed data from over 180,000
• 8:55
  acetaminophen users compared to more than 400,000 non-users spanning two decades, from
• 9:02
  1998 to 2018.
• 9:05
  The findings suggest that acetaminophen, also known as paracetamol, is linked to an increased
• 9:11
  risk of serious medical complications in older adults.
• 9:15
  Acetaminophen is widely recognized for its pain-relieving and fever-reducing properties
• 9:21
  and is often included in a variety of over-the-counter medications, such as those for
• 9:26
  colds and flu.
• 9:28
  However, this study raises concerns about its safety profile in the elderly population.
• 9:35
  According to the research, long-term use of acetaminophen in older individuals was
• 9:40
  associated with an increased risk of conditions such as peptic ulcer bleeding, heart failure,
• 9:45
  hypertension, and chronic kidney disease.
• 9:48
  Professor Weiya Zhang from the University of Nottingham, who led the study, emphasized the
• 9:54
  need for caution when prescribing acetaminophen, particularly for long-term
• 9:59
  conditions like osteoarthritis.
• 10:01
  He noted that while further research is necessary to confirm these findings, the
• 10:06
  minimal pain-relief effect of acetaminophen calls into question its role as a first-line
• 10:12
  treatment for chronic pain in older adults.
• 10:16
  Dr.
• 10:16
  Marc Siegel, a clinical professor of medicine at New York University Langone Health,
• 10:21
  commented on the study's implications.
• 10:25
  He pointed out that while acetaminophen is generally considered safe, the emerging
• 10:29
  evidence suggests it might share some adverse effects with nonsteroidal anti-inflammatory
• 10:34
  drugs, such as gastrointestinal bleeding.
• 10:37
  Dr.
• 10:37
  Siegel also highlighted the importance of ongoing post-market analysis to continually
• 10:42
  assess the safety of medications.
• 10:45
  Gerontologist Dr.
• 10:46
  Macie P.
• 10:48
  Smith also weighed in, stressing the importance of tailored medical advice for older adults.
• 10:53
  She advised that people over the age of 65 should consult their healthcare providers
• 10:57
  before taking any over-the-counter medications, including those containing acetaminophen.
• 11:02
  Dr.
• 11:03
  Smith underscored the need for specialized care in geriatrics, as older bodies and brains may
• 11:08
  not tolerate medications in the same way they did at a younger age.
• 11:13
  This study serves as a crucial reminder that all medications, even those available
• 11:18
  over-the-counter, can have significant side effects, particularly when used chronically.
• 11:25
  It reinforces the need for older adults to be vigilant about their medication use and to have
• 11:31
  open discussions with their healthcare providers about the risks and benefits of their
• 11:34
  treatment options.
• 11:37
  Let's delve into an intriguing study published recently in the European Heart Journal, which
• 11:42
  explores the link between wine consumption and cardiovascular health.
• 11:47
  This research builds on prior findings suggesting that moderate wine intake could be
• 11:51
  beneficial for heart health.
• 11:53
  What makes this study particularly noteworthy is its use of a biomarker to objectively
• 11:59
  measure wine consumption and its effects on cardiovascular disease risk.
• 12:04
  The study, part of the larger PREDIMED trial, used urinary tartaric acid levels as a
• 12:10
  surrogate for wine consumption.
• 12:12
  Tartaric acid is a compound primarily found in grapes, and thus in wine, making it a reliable
• 12:18
  indicator of how much wine a person consumes.
• 12:21
  By measuring this biomarker, researchers aimed to eliminate the biases and misclassifications
• 12:27
  commonly seen in self-reported dietary intake studies.
• 12:31
  According to the study, participants who consumed between twelve to thirty-five glasses
• 12:36
  of wine per month showed a significantly lower risk of combined heart failure, myocardial
• 12:41
  infarction, stroke, and cardiovascular death over a median follow-up period of nine years.
• 12:48
  This finding supports the idea that certain bioactive compounds in wine may contribute to
• 12:52
  cardiovascular protection.
• 12:55
  Interestingly, the protective effects were not observed at very low or very high levels of
• 13:00
  wine consumption, suggesting that moderation is key.
• 13:04
  Participants with the lowest tartaric acid levels, indicating minimal wine intake, and
• 13:09
  those with the highest levels, indicating excessive intake, did not experience the same
• 13:14
  cardiovascular benefits.
• 13:17
  The study authors, led by Dr.
• 13:19
  Ramon Estruch from the University of Barcelona, highlight the methodological advancement of
• 13:24
  using urinary tartaric acid as an objective measure.
• 13:28
  This approach provides a more accurate assessment of wine consumption and its health
• 13:32
  effects, which is crucial given the ongoing debates in nutritional epidemiology regarding
• 13:38
  alcohol's impact on health.
• 13:40
  In an accompanying editorial, Dr.
• 13:43
  Giovanni de Gaetano and colleagues praised the study for its innovative use of biomarkers,
• 13:48
  noting that this method could help clarify the complex relationship between alcohol
• 13:54
  consumption and health outcomes.
• 13:57
  They emphasized that humans often underreport their alcohol intake, making objective measures
• 14:03
  like tartaric acid invaluable for research.
• 14:07
  The implications of these findings are significant for public health recommendations.
• 14:12
  They suggest that moderate wine consumption, in real-life conditions, may have more beneficial
• 14:19
  effects on cardiovascular health than previously thought, without the artificial
• 14:24
  influences of a clinical trial setting.
• 14:27
  However, the researchers caution that these results may not be generalizable beyond the
• 14:31
  older Mediterranean population studied in the PREDIMED trial.
• 14:36
  While the exact mechanisms through which wine confers its cardiovascular benefits remain
• 14:42
  unclear, polyphenols found in wine are believed to play a role.
• 14:47
  These compounds have anti-inflammatory properties, which could contribute to the
• 14:51
  observed cardioprotective effects.
• 14:54
  Overall, this study underscores the potential cardiovascular benefits of moderate wine
• 15:00
  consumption while highlighting the importance of using objective biomarkers in nutritional
• 15:05
  research.
• 15:07
  As always, it's crucial to approach such findings with caution and consider individual
• 15:12
  health circumstances when making dietary choices.
• 15:17
  Seed oils have been making headlines recently, stirring up concerns about their potential
• 15:22
  health risks.
• 15:23
  Earlier this week, a study published in the journal Gut sparked headlines that likened seed
• 15:28
  oils to colon cancer fuel.
• 15:31
  However, some experts argue that these headlines are misleading.
• 15:35
  So, let's dive deeper into what seed oils are and whether they pose any health risks.
• 15:41
  Seed oils are distinct from other vegetable oils because they're derived from the seeds of
• 15:46
  plants, rather than the fruit.
• 15:48
  For instance, sunflower oil comes from sunflower seeds, while olive oil is extracted
• 15:53
  from olives, which are the fruit of the plant.
• 15:57
  Some seed oils, like sesame oil, are appreciated not only for their health benefits
• 16:02
  but also for their aromatic qualities, making them a popular choice in many culinary
• 16:07
  applications.
• 16:09
  Now, regarding health risks, according to Kristina Petersen, an associate professor of
• 16:14
  nutritional sciences at Pennsylvania State University, seed oils do not pose health risks
• 16:20
  based on current evidence.
• 16:22
  In fact, substituting seed oils for fats like butter and other animal fats can actually
• 16:27
  improve blood cholesterol levels and reduce the risk of diseases such as heart disease and Type
• 16:33
  2 diabetes.
• 16:35
  Dr.
• 16:36
  Steven Shamah, director of endoscopy at Lenox Hill Hospital, emphasizes the importance of
• 16:41
  moderation.
• 16:42
  Like all oils, seed oils contain fats, which are essential for a balanced diet, but they
• 16:48
  should be consumed in appropriate quantities.
• 16:50
  The type of fat is also crucial—seed oils are rich in unsaturated fats, including both
• 16:56
  monounsaturated and polyunsaturated fats, which have been shown to decrease 'bad' cholesterol
• 17:02
  and increase 'good' cholesterol.
• 17:05
  Seed oils are particularly rich in omega-6 fatty acids, such as linoleic acid, which is
• 17:11
  essential for bodily functions.
• 17:13
  However, Dr.
• 17:15
  Shamah mentions that linoleic acid should be balanced with omega-3 fatty acids.
• 17:20
  He warns that while linoleic acid is beneficial in small amounts, overconsumption can stress
• 17:26
  beneficial bacteria in the gut microbiome, a common issue in modern diets due to the
• 17:30
  prevalence of seed oils in processed foods.
• 17:34
  Critics of seed oils argue that linoleic acid can break down into toxins when used in
• 17:40
  cooking, potentially leading to inflammation and other health issues.
• 17:46
  Despite these claims, experts like Petersen and Dr.
• 17:50
  Christopher Gardner, a professor of medicine at Stanford University, refute the notion that
• 17:55
  omega-6 fatty acids are harmful.
• 17:58
  Clinical data shows that markers of inflammation do not change with omega-6 fatty
• 18:02
  acid consumption, and only a small fraction is converted into arachidonic acid, which is not a
• 18:08
  cause for concern.
• 18:10
  Dr.
• 18:10
  Gardner points out that omega-6 fatty acids are polyunsaturated fats that the body needs but
• 18:17
  cannot produce on its own, so they must be obtained through diet.
• 18:22
  These fats help lower bad cholesterol, thereby reducing the risk of heart disease and stroke.
• 18:29
  The American Heart Association supports the inclusion of omega-6 fatty acids as part of a
• 18:35
  healthy diet.
• 18:37
  A common misconception is that people may unknowingly consume large amounts of seed oils
• 18:41
  through processed foods.
• 18:43
  However, rather than focusing on the oils themselves, Dr.
• 18:47
  Gardner suggests the real issue lies in the overconsumption of ultra-processed foods, which
• 18:53
  often contain unhealthy levels of ingredients like high-fructose corn syrup, sugar, and
• 18:58
  sodium.
• 19:00
  Commonly used seed oils include canola, corn, sunflower, pumpkin seed, chia seed, sesame,
• 19:07
  peanut, grapeseed, and soybean oils.
• 19:11
  In contrast, oils such as olive, avocado, and coconut are not derived from seeds but from the
• 19:17
  fruit of the plant.
• 19:21
  Now, let's turn our focus to a topic that's causing quite a stir in the United States: the
• 19:26
  health insurance industry and the growing discontent among Americans.
• 19:31
  The recent tragic event involving the fatal shooting of UnitedHealthcare's Chief Executive
• 19:36
  Officer, Brian Thompson, has brought a renewed focus on the flaws and challenges within the
• 19:41
  U.S.
• 19:41
  health-care system.
• 19:43
  This incident has unleashed a wave of anger and frustration towards the insurance industry,
• 19:49
  with patients, advocacy groups, and experts alike voicing their concerns.
• 19:55
  The U.S.
• 19:55
  spends more on health care than any other country, yet it ranks low in terms of life
• 20:00
  expectancy among wealthy nations.
• 20:03
  This discrepancy highlights significant issues within the system that many say is broken or
• 20:08
  deeply flawed.
• 20:10
  One of the key challenges is the lack of consensus on the root causes of these problems
• 20:15
  and how to effectively address them.
• 20:18
  The U.S.
• 20:19
  health insurance system is predominantly run by private-sector companies like UnitedHealth
• 20:24
  Group, CVS Health, and Cigna, operating mainly as profit-driven enterprises.
• 20:30
  This contrasts with many other developed nations where health care is more publicly
• 20:35
  managed, focusing on patient care rather than profits.
• 20:40
  Patients often face high premiums, denied claims, and unexpected medical bills, which can
• 20:47
  lead to financial distress and, in some cases, prevent them from receiving necessary care.
• 20:54
  The use of technology, including artificial intelligence, by insurers to manage claims has
• 21:00
  also been criticized for leading to inaccurate denials.
• 21:04
  This complex landscape is further complicated by information asymmetry, where patients may
• 21:10
  not fully understand their coverage details, while insurers have extensive knowledge of the
• 21:14
  health-care networks and policies.
• 21:17
  This can leave patients feeling confused and vulnerable, especially when their claims are
• 21:21
  denied or when they encounter hidden costs.
• 21:25
  Experts argue that while insurers must control costs to keep premiums manageable, this often
• 21:31
  comes at the expense of patient care.
• 21:34
  Many believe that the industry's focus on profit maximization, coupled with limited
• 21:39
  competition due to consolidation, exacerbates these issues.
• 21:44
  Despite these challenges, there are calls for reform.
• 21:47
  Suggestions include increasing transparency within the industry, more robust legislative
• 21:52
  efforts to protect patients from surprise medical bills, and addressing systemic issues
• 21:57
  such as provider shortages that drive up costs.
• 22:01
  While significant changes may not happen overnight, individuals like Michael Hinton, who
• 22:06
  has navigated his own health-care challenges, emphasize the importance of patients taking an
• 22:11
  active role in their health management.
• 22:13
  This includes being well-informed about their conditions, insurance policies, and seeking
• 22:18
  help from advocacy organizations when necessary.
• 22:22
  As we conclude today's episode, it's clear that the U.S.
• 22:26
  health-care system is at a critical juncture, with a pressing need for reforms that
• 22:30
  prioritize patient care and accessibility.
• 22:34
  The tragic events surrounding Brian Thompson's death have underscored these systemic issues
• 22:40
  and reignited the debate on how to create a fairer, more effective health-care system.
• 22:47
  Thank you for joining me on Morning Medical with Dr.
• 22:50
  Chow.
• 22:51
  As we continue to explore the evolving landscape of health and medicine, remember to
• 22:55
  stay informed and proactive about your health and well-being.
• 22:59
  Until next time, take care and stay healthy.
