  Welcome to another episode of Morning Medical with Dr.
• 0:03
  Chow!
• 0:04
  I'm your host, Dr.
• 0:06
  Chi-Ming Chow, coming to you from Toronto, Canada.
• 0:09
  As always, we're here to bring you the latest in medical and health news from around the
• 0:13
  world, and today we've got some important updates.
• 0:17
  Our first topic is a startling revelation about diabetes, a condition that affects millions
• 0:23
  globally but often goes unnoticed until it's too late.
• 0:29
  A recent study published in The Lancet Diabetes & Endocrinology has revealed that nearly half
• 0:35
  of the people living with diabetes worldwide are undiagnosed.
• 0:39
  That's right, about forty-four percent of individuals aged fifteen and older who have
• 0:44
  diabetes do not even know it.
• 0:46
  This study is a comprehensive analysis that reviewed data from two hundred and four
• 0:52
  countries and territories, covering a span from the year two thousand to two thousand
• 0:57
  twenty-three.
• 0:58
  The research highlights a significant gap in diabetes diagnosis, particularly among younger
• 1:04
  people under the age of thirty-five.
• 1:06
  Only twenty percent of young adults with diabetes are aware of their condition.
• 1:12
  This is a stark contrast to older adults, who are more likely to be diagnosed due to routine
• 1:17
  screenings.
• 1:18
  Unfortunately, many people only discover their condition after complications arise, which
• 1:25
  underscores the importance of early detection and regular screenings.
• 1:30
  According to Lauryn Stafford, the lead author of the study, there's a notable disparity in
• 1:35
  diabetes diagnosis across different regions and income levels.
• 1:40
  High-income countries generally fare better in diagnosing diabetes compared to low- and
• 1:46
  middle-income countries.
• 1:48
  In the United States, for example, eleven point six percent of Americans have diabetes,
• 1:54
  according to data from the American Diabetes Association.
• 1:58
  Rita Kalyani from Johns Hopkins University emphasizes the importance of early diabetes
• 2:03
  diagnosis to prevent long-term complications such as heart disease, kidney failure, and
• 2:08
  nerve damage.
• 2:09
  Symptoms like increased thirst, frequent urination, blurry vision, and unexpected weight
• 2:15
  loss are indicators that one should get screened.
• 2:19
  However, many people with diabetes are asymptomatic in the early stages, which makes
• 2:24
  awareness and proactive health checks crucial.
• 2:28
  Interestingly, the study also notes that only about forty percent of people with treated
• 2:33
  diabetes are achieving optimal blood sugar control.
• 2:37
  This is surprising given the availability of effective treatments such as insulin and
• 2:42
  Metformin.
• 2:43
  Challenges in managing diabetes often arise due to concurrent health issues like hypertension
• 2:49
  or chronic kidney disease, which complicate treatment.
• 2:53
  Preventing diabetes, particularly type two diabetes, is possible through lifestyle
• 2:59
  changes.
• 3:00
  Reducing red and processed meat intake, incorporating more plant-based foods, and
• 3:05
  engaging in regular physical activity like brisk walking can significantly lower one's
• 3:10
  risk.
• 3:11
  As Lauryn Stafford points out, focusing on prevention is just as crucial as diagnosis to
• 3:17
  curb the rising prevalence of diabetes.
• 3:21
  A new study has found that a common artificial sweetener, sucralose, could reduce the
• 3:26
  effectiveness of cancer treatments, particularly immunotherapy.
• 3:30
  This research was conducted by the University of Pittsburgh and the University of Pittsburgh
• 3:35
  Medical Center Hillman Cancer Center.
• 3:38
  The study focused on patients with melanoma, a deadly form of skin cancer, and nonsmall cell
• 3:44
  lung cancer, which is the most prevalent type of lung cancer.
• 3:49
  The study included one hundred thirty-two patients who were undergoing treatment with
• 3:53
  anti-PD1 immunotherapy, either alone or in combination with chemotherapy.
• 3:59
  These patients completed dietary questionnaires that detailed their consumption of artificial
• 4:04
  sweeteners.
• 4:06
  The findings revealed that those who consumed high levels of sucralose had a poorer response
• 4:11
  to immunotherapy and reduced survival rates compared to those who consumed low amounts.
• 4:18
  Senior author Diwakar Davar, associate professor of medicine at the University of
• 4:23
  Pittsburgh and a medical oncologist at the University of Pittsburgh Medical Center Hillman
• 4:28
  Cancer Center, highlighted that sucralose impeded the effectiveness of immunotherapies
• 4:34
  across various cancer types, stages, and treatment modalities.
• 4:39
  This raises concerns about the potential impact of dietary habits on cancer treatment outcomes.
• 4:46
  Interestingly, the study also found a potential solution to this issue.
• 4:50
  By increasing levels of the amino acid arginine, the negative effects of sucralose on
• 4:55
  immunotherapy could be counteracted.
• 4:58
  In a mouse study, supplements that boosted arginine levels were shown to enhance the
• 5:03
  effectiveness of immunotherapy, despite the presence of sucralose.
• 5:08
  Lead author Abby Overacre, an assistant professor in the Department of Immunology at
• 5:13
  the University of Pittsburgh and University of Pittsburgh Medical Center Hillman Cancer
• 5:18
  Center, noted that while it is easy to suggest patients stop consuming diet soda, it may not
• 5:25
  be realistic given the challenges cancer patients already face.
• 5:30
  Therefore, meeting patients where they are and providing feasible dietary recommendations is
• 5:36
  crucial.
• 5:37
  The study also suggests that sucralose alters the gut microbiome, reducing levels of
• 5:43
  arginine, which is essential for T-cell function.
• 5:47
  T-cells are a key component of immunotherapy drugs, and when arginine levels are depleted,
• 5:53
  T-cells cannot function properly, diminishing the effectiveness of the treatment.
• 5:59
  Looking ahead, the researchers plan to conduct a clinical trial investigating arginine
• 6:04
  supplementation in human cancer patients.
• 6:07
  They'll also explore the impact of other sugar substitutes on the effectiveness of
• 6:12
  immunotherapy.
• 6:13
  While this study provides new insights, it's important to note that it has certain
• 6:17
  limitations, including reliance on animal research and self-reported dietary data, which
• 6:23
  can be subject to bias.
• 6:26
  As always, patients undergoing cancer treatment should follow guidance from their healthcare
• 6:30
  team.
• 6:31
  The study was supported by the National Institutes of Health, the Damon Runyon Cancer
• 6:35
  Research Foundation, and Gateway for Cancer Research.
• 6:39
  It's crucial to continue research in this field to better understand how dietary factors
• 6:45
  influence cancer treatment outcomes.
• 6:49
  A recent study published in JAMA Neurology has provided new insights into the relationship
• 6:55
  between air pollution and Alzheimer's disease.
• 6:59
  The study, conducted by researchers including Edward Lee from the University of Pennsylvania
• 7:05
  Perelman School of Medicine, examined data from six hundred two autopsy cases collected over
• 7:11
  more than two decades, from nineteen ninety-nine to two thousand twenty-two.
• 7:17
  The research found that exposure to higher levels of fine particulate matter, specifically
• 7:21
  particles less than two point five micrometers, before death was linked to more severe
• 7:26
  Alzheimer's disease pathology.
• 7:29
  In other words, people who were exposed to worse air quality had more significant changes
• 7:35
  in their brains associated with Alzheimer's disease.
• 7:39
  Furthermore, among a subset of two hundred eighty-seven cases, those with higher exposure
• 7:44
  to fine particulate matter also experienced greater cognitive and functional impairment.
• 7:50
  The study indicated that sixty-three percent of this association between air pollution and
• 7:55
  impaired cognition was mediated by Alzheimer's disease neuropathologic changes.
• 8:01
  Edward Lee noted that while air pollution is likely to exacerbate Alzheimer's disease, it
• 8:06
  may also worsen other conditions like cerebrovascular disease.
• 8:10
  However, this particular study focused primarily on neurodegenerative processes
• 8:16
  related to Alzheimer's disease.
• 8:18
  The findings emphasize the importance of environmental factors as modifiable risks for
• 8:23
  dementia, aligning with the Lancet Commission's identification of air pollution as a key risk
• 8:28
  factor.
• 8:30
  The study utilized a prediction model to estimate the mean concentration of fine
• 8:35
  particulate matter at participants' residential addresses one year before their death or their
• 8:41
  last cognitive assessment.
• 8:43
  The research adjusted for demographic factors and genetic markers such as the APOE4 gene,
• 8:48
  which is known to influence Alzheimer's risk.
• 8:52
  It's worth noting that the study's cohort had a median age of seventy-eight years, and more
• 8:56
  than half of the participants had at least one APOE4 allele.
• 9:01
  Additionally, a significant portion of the cohort exhibited severe Alzheimer's pathology,
• 9:07
  with over sixty-two percent showing high neuropathologic changes.
• 9:12
  This underscores the complex interplay between genetic, environmental, and pathological
• 9:17
  factors in Alzheimer's disease.
• 9:20
  While the study provides valuable insights, the researchers acknowledged certain limitations.
• 9:27
  The demographic skew of the cohort may limit the generalizability of the findings to broader
• 9:34
  populations.
• 9:35
  Furthermore, the cohort was enriched for Alzheimer's dementia cases and did not include
• 9:41
  many individuals with vascular dementia, potentially underestimating the association
• 9:46
  between air pollution and cerebrovascular disease.
• 9:51
  In Thunder Bay, Ontario, there's a significant development in the realm of primary care.
• 9:57
  The Port Arthur Health Centre has recently expanded its team by bringing on ten new
• 10:01
  doctors, a move aimed at addressing the gap in primary care services in the region.
• 10:07
  This expansion includes six new family physicians and four specialists, which consists
• 10:12
  of two ophthalmologists, a cardiologist, and a psychiatrist.
• 10:17
  Dr.
• 10:18
  John Coccimiglio, who has been practicing family medicine in Thunder Bay for about seven
• 10:23
  years, estimates that around forty thousand people in the area are currently without a
• 10:27
  family doctor.
• 10:29
  This initiative is a step towards alleviating that shortage.
• 10:33
  The city of Thunder Bay, with a population of approximately one hundred thirty-three
• 10:38
  thousand, has faced ongoing challenges in providing adequate access to primary care.
• 10:43
  While the city is home to several clinics and two hospitals, the demand for family doctors
• 10:49
  remains high.
• 10:50
  The Ontario College of Family Physicians reports that about two point five million
• 10:55
  residents in Ontario are without a family doctor, underscoring a broader provincial
• 11:00
  issue.
• 11:01
  Dr.
• 11:01
  Coccimiglio expressed that the Port Arthur Health Centre aims to roster upwards of ten
• 11:06
  thousand patients, significantly increasing the center's capacity to deliver primary care
• 11:11
  services.
• 11:13
  John Marrello, the Chief Executive Officer of the Port Arthur Health Centre, emphasized the
• 11:18
  importance of this expansion in a recent news release.
• 11:22
  "By welcoming new family physicians, we're strengthening our ability to provide timely,
• 11:28
  patient-centered care," he stated.
• 11:31
  This expansion is not only about increasing numbers but also about ensuring that more
• 11:35
  residents can establish ongoing relationships with dedicated healthcare providers.
• 11:41
  Some of these new positions were filled with the help of the province's Practice Ready
• 11:46
  Ontario program, which allows foreign-trained physicians to convert their medical licenses to
• 11:51
  practice in Canada.
• 11:53
  This program is crucial in addressing the shortages and bringing diverse expertise into
• 11:59
  the healthcare system.
• 12:00
  Additionally, the Port Arthur Health Centre's partnership with the Northern Ontario School of
• 12:06
  Medicine University has been instrumental in attracting new talent.
• 12:11
  As a teaching site, the center provides learning opportunities for medical students and
• 12:15
  residents, which also helps in recruitment.
• 12:19
  Dr.
• 12:19
  Coccimiglio highlighted the appeal of Thunder Bay as a place to live and work, noting its
• 12:24
  recreational facilities, natural environment, and vibrant community life.
• 12:29
  He mentioned that the city offers a wide scope of practice, allowing doctors to encounter a
• 12:35
  variety of complex cases.
• 12:37
  This variety can be particularly attractive to medical professionals seeking a dynamic work
• 12:43
  environment.
• 12:44
  The center's efforts align with the Ontario government's Primary Care Action Plan, which
• 12:50
  aims to connect every resident with a primary care provider by twenty twenty-nine.
• 12:55
  The Port Arthur Health Centre hopes to be a key piece in that puzzle.
• 13:00
  For those interested in becoming a patient at the Port Arthur Health Centre, the process
• 13:05
  involves completing a wait-list application form in person at their location on Court
• 13:10
  Street North.
• 13:11
  This expansion is a promising step towards improving healthcare access in Thunder Bay, and
• 13:16
  it represents a broader effort to enhance primary care services across Ontario.
• 13:23
  In today's world, we're witnessing a rapid evolution in the realm of self-monitoring and
• 13:27
  personal health data collection.
• 13:29
  Dr.
• 13:31
  Fred Pelzman, a contributing writer for MedPage Today, recently highlighted some intriguing
• 13:36
  trends in this area.
• 13:38
  He shared a story about a patient who, despite not having diabetes, was eager to compare
• 13:43
  glucose readings from various devices, including a smartwatch, continuous glucose
• 13:48
  monitor, and traditional finger-prick glucometer.
• 13:52
  This anecdote underscores the growing consumer interest in health tracking technologies.
• 13:58
  It's fascinating how these devices have become part of our daily lives, offering insights into
• 14:03
  our health that we might not have anticipated.
• 14:07
  For instance, my own Apple smartwatch provides updates on heart rate trends, walking distance,
• 14:14
  and even sound levels in my environment—data I didn't even realize it was collecting.
• 14:19
  Yet, as Dr.
• 14:20
  Pelzman points out, despite the wealth of information, making meaningful lifestyle
• 14:26
  changes based on these insights can be challenging.
• 14:30
  The potential benefits of self-monitoring are significant.
• 14:34
  When used effectively, home blood pressure monitoring can improve control, motivate
• 14:40
  patients, and enhance medication adherence, ultimately leading to better health outcomes.
• 14:46
  Similarly, devices like Oura rings and sleep apps can detect sleep apnea or other
• 14:51
  sleep-related issues, offering an opportunity for early intervention.
• 14:56
  However, there's a flipside to this data deluge.
• 14:59
  As Dr.
• 15:00
  Pelzman notes, the sheer volume of information can be overwhelming.
• 15:04
  Patients might bring in extensive data collected from various sources, such as
• 15:09
  sophisticated home devices that monitor everything from urine pH to gut microbiome
• 15:15
  changes.
• 15:16
  While these technologies hold promise, they also pose the challenge of sifting through the
• 15:21
  noise to find actionable insights.
• 15:24
  As we advance into this data-rich future, it's crucial to consider how we integrate these
• 15:29
  insights into patient care.
• 15:32
  The risk of data overload is real, potentially obscuring the important signals we need to
• 15:37
  address.
• 15:38
  Imagine a world where smart systems continuously monitor our health, alerting us to
• 15:44
  changes in elderly relatives' conditions, from hydration levels to potential infections.
• 15:50
  While this could enhance care, it also raises questions about privacy and the human touch in
• 15:56
  healthcare.
• 15:57
  Dr.
• 15:58
  Pelzman reminds us that, despite the influx of data, the human element remains vital.
• 16:05
  Perhaps instead of relying solely on technology, we should encourage more frequent
• 16:10
  personal interactions, like family visits to check on loved ones.
• 16:15
  The balance between leveraging technology and maintaining personal connections will be key as
• 16:20
  we navigate this evolving landscape.
• 16:24
  Looking forward, the challenge will be to develop systems that not only collect data but
• 16:29
  also help us interpret it in meaningful ways.
• 16:32
  The rise of self-monitoring technologies is an exciting frontier in healthcare, but it
• 16:38
  requires thoughtful integration into our practices to truly benefit patients.
• 16:44
  Thanks for joining us on this episode of Morning Medical with Dr.
• 16:47
  Chow.
• 16:48
  We hope you found today's discussions insightful.
• 16:51
  Remember, staying informed is the first step towards better health.
• 16:54
  Be sure to tune in tomorrow for more updates from the world of medicine.
• 16:58
  Stay healthy, and take care!
