  Welcome to another episode of "Morning Medical with Doctor Chow." I'm your host, Doctor
• 0:05
  Chi-Ming Chow.
• 0:06
  Today, we're diving into some fascinating developments in the world of health and
• 0:11
  medicine.
• 0:12
  Let's start with a study that raises questions about how the flu virus spreads and what we can
• 0:17
  do to prevent it.
• 0:22
  Researchers from the University of Maryland Schools of Public Health and Engineering and
• 0:27
  the School of Medicine in Baltimore conducted a unique study to understand the transmission of
• 0:33
  the flu.
• 0:34
  They took a bold approach by placing flu-positive college students in a hotel room
• 0:39
  with healthy middle-aged adult volunteers.
• 0:43
  This experiment is reportedly the first clinical trial to investigate how the flu
• 0:48
  spreads from naturally infected individuals to those who are uninfected.
• 0:55
  The study was conducted in a quarantined floor of a Baltimore-area hotel, where the
• 1:00
  participants, including 11 healthy volunteers, lived for two weeks.
• 1:05
  They simulated typical social interactions like conversations, physical activities such as
• 1:10
  yoga, and even shared objects like pens and tablets.
• 1:14
  Researchers closely monitored the participants, performing daily nasal swabs and collecting
• 1:20
  saliva and blood samples to test for antibodies.
• 1:23
  They also measured the viral exposure in the volunteers' breathing air and the ambient air
• 1:28
  of the activity room.
• 1:30
  Interestingly, at the end of the experiment, none of the healthy individuals contracted the
• 1:35
  flu.
• 1:36
  Researchers identified several factors that contributed to this surprising result.
• 1:42
  One major factor was the lack of coughing among the infected students, who were holding a lot
• 1:47
  of the virus in their noses but expelled only small amounts into the air.
• 1:52
  Proper ventilation also played a significant role in preventing the flu's spread.
• 1:58
  The air in the study room was continuously mixed by a heater and dehumidifier, diluting
• 2:04
  any virus present in the air.
• 2:06
  Doctor Jianyu Lai, a post-doctoral research scientist and the study's lead data analyst,
• 2:12
  noted that coughing is a key factor in increasing the likelihood of flu transmission.
• 2:17
  He emphasized that proper air movement and ventilation were crucial in halting the spread
• 2:22
  of the virus in this study.
• 2:24
  Additionally, the middle-aged adults in the study were generally less susceptible to
• 2:29
  influenza compared to younger adults.
• 2:33
  Doctor Donald Milton, a professor at the School of Public Health’s Department of Global,
• 2:38
  Environmental and Occupational Health, highlighted that their findings could be
• 2:42
  essential for updating international infection-control guidelines.
• 2:46
  He pointed out that being indoors, face-to-face with others, especially in poorly ventilated
• 2:52
  spaces, can be risky for flu transmission.
• 2:56
  However, their study suggests that portable air purifiers that mix and clean the air could be
• 3:02
  beneficial.
• 3:04
  He also recommended wearing masks, particularly N95 masks, when close to someone who is
• 3:10
  coughing.
• 3:11
  This study is particularly relevant as we navigate the flu season, which has already seen
• 3:16
  approximately 11 million flu illnesses and around 5,000 deaths in the 2025-2026 influenza
• 3:25
  season, according to data from the Centers for Disease Control and Prevention.
• 3:30
  With a large share of current flu cases caused by the new influenza A subclade K variant,
• 3:36
  understanding how the flu spreads and how to mitigate it is more important than ever.
• 3:42
  In an exciting development for healthcare accessibility, Manitobans can now carry their
• 3:48
  health cards digitally on their mobile devices.
• 3:51
  The Manitoba government announced that residents registered with the province's health
• 3:56
  system can request a digital version of their health card starting this week.
• 4:02
  This digital option is a step forward from the plastic health cards introduced last year,
• 4:07
  which replaced the easily damaged paper versions.
• 4:11
  Premier Wab Kinew humorously remarked that transitioning from paper to plastic was like
• 4:16
  moving Manitoba into the 1980s, and now with digital cards, they're stepping into the 2000s,
• 4:23
  possibly even the 2020s.
• 4:26
  The shift to digital cards is expected to make accessing care more convenient, eliminating the
• 4:32
  need to carry a physical card.
• 4:35
  This is especially beneficial in emergencies, like evacuations due to wildfires, where people
• 4:42
  might not have time to gather all their documents.
• 4:45
  Health Minister Uzoma Asagwara highlighted the importance of having your health card on your
• 4:50
  phone during such emergencies.
• 4:53
  It simplifies one aspect of a stressful situation, making it easier to access necessary
• 4:58
  healthcare services.
• 5:00
  The digital cards will be stored in the MB Wallet app, which also allows users to book
• 5:05
  clinic appointments through the MediNav online booking system.
• 5:09
  Parents can store their children's cards in the app, providing a centralized place for managing
• 5:14
  family health information.
• 5:16
  The government assures that the MB Wallet app has been developed with strong security
• 5:21
  measures to protect health information.
• 5:23
  Premier Kinew mentioned that there are plans to expand the app's functionality to include other
• 5:29
  licenses, like hunting and fishing.
• 5:31
  He also addressed concerns about privacy, emphasizing that opting for a digital health
• 5:36
  card is entirely optional and not mandatory for residents.
• 5:41
  The introduction of the digital health card cost the province approximately 1.9 million
• 5:47
  dollars.
• 5:47
  Residents interested in obtaining this new digital feature must have a My Manitoba Health
• 5:53
  Card account and download the MB Wallet app on their mobile devices.
• 5:57
  They can choose between the digital or plastic version of the health card or opt to have both.
• 6:02
  This development is a significant step towards modernizing healthcare access in Manitoba,
• 6:08
  making it more adaptable to the needs of its residents.
• 6:13
  Fred Pelzman, a contributing writer for MedPage Today, has shared some insightful reflections
• 6:18
  on the current state of our healthcare system and what resolutions we might consider in the
• 6:22
  New Year.
• 6:24
  As we step into 2026, many of us have set personal goals, and Fred's primary resolution
• 6:30
  is to improve his hydration habits.
• 6:33
  He humorously recounts how, during his residency, he and his colleagues often stayed
• 6:39
  in a state of pre-renal dehydration simply to avoid the frequent bathroom breaks that would
• 6:44
  disrupt their busy schedules.
• 6:47
  Yet, he acknowledges the importance of hydration and how he is now making a concerted
• 6:52
  effort to drink more water, even if it means more trips to the bathroom.
• 6:58
  Beyond personal resolutions, Fred urges us to focus on broader issues within the healthcare
• 7:03
  system.
• 7:04
  He paints a picture of a system that is fractured and expensive, with many patients
• 7:08
  struggling to access the care they need.
• 7:11
  From changing formularies and unauthorized tests to insurers dropping contracts, patients
• 7:16
  are facing numerous barriers in getting healthcare.
• 7:20
  Fred emphasizes the necessity of speaking up for a better system, one where healthcare is a
• 7:26
  right, not a privilege dictated by insurance companies or pharmaceutical firms.
• 7:32
  Fred envisions a future where we build a truly patient-centered medical home, a concept he
• 7:38
  describes as "concierge medicine for all." This vision involves smarter systems, improved
• 7:44
  workflows, and the use of artificial intelligence to catch errors and close gaps in
• 7:49
  care.
• 7:50
  He believes in redistributing the financial structures of healthcare and establishing a
• 7:55
  robust public health system free from political bias, ensuring that patients are treated
• 8:00
  equally and receive the care they need.
• 8:03
  Fred also highlights the importance of addressing social determinants of health, such
• 8:07
  as access to clean water, decent housing, nutritious food, and safe environments for
• 8:13
  exercise.
• 8:14
  He acknowledges that while we may face resistance and be told to "stay in our lanes,"
• 8:19
  it is crucial to chip away at these issues.
• 8:22
  Every small effort can lead to significant change, as a chip leads to a crack, a crack to
• 8:27
  a crumble, and ultimately, the wall comes tumbling down.
• 8:31
  In closing, Fred encourages us to keep discussing what makes sense in healthcare and
• 8:37
  to continue reaching out for new ideas to improve the system.
• 8:40
  He wishes everyone a healthy and happy New Year, inviting us to join him in the journey of
• 8:45
  creating a better healthcare environment for all.
• 8:50
  The term 'forever chemicals' refers to a group of man-made substances known as per- and
• 8:56
  polyfluoroalkyl substances, or PFAS.
• 9:01
  These chemicals have been widely used in a variety of consumer products, including
• 9:06
  non-stick cookware, water-repellent clothing, and firefighting foams, due to their ability to
• 9:11
  resist heat, water, and oil.
• 9:14
  However, the very same properties that make PFAS so useful also make them incredibly
• 9:20
  persistent in the environment, and they can take thousands of years to break down.
• 9:26
  This persistence has led to growing concerns about their potential impact on human health
• 9:30
  and the environment.
• 9:33
  Recent reports have raised alarms about the presence of PFAS in raincoats and other
• 9:39
  waterproof clothing.
• 9:40
  These chemicals are often used to provide water and stain resistance, but their presence in
• 9:46
  everyday items means they can be released into the environment through washing and wear.
• 9:52
  Once in the environment, PFAS can accumulate in water, soil, and even in the bodies of living
• 9:58
  organisms, including humans.
• 10:01
  The health implications of PFAS exposure are still being studied, but there is evidence to
• 10:07
  suggest they can have adverse effects.
• 10:10
  Some studies have linked PFAS exposure to a range of health issues, such as hormone
• 10:16
  disruption, liver damage, and even increased risk of certain cancers.
• 10:21
  The potential for these chemicals to affect human health has led to increased scrutiny and
• 10:26
  calls for regulation.
• 10:28
  In response to these concerns, some manufacturers are beginning to phase out the
• 10:32
  use of PFAS in their products.
• 10:35
  They are exploring alternative materials and technologies that can provide similar
• 10:38
  water-repellent properties without the environmental and health risks associated with
• 10:43
  PFAS.
• 10:45
  However, finding effective substitutes has proven challenging, and many products on the
• 10:50
  market still contain these persistent chemicals.
• 10:53
  As consumers, it's important to be aware of the potential presence of PFAS in the products we
• 10:59
  use.
• 11:00
  Checking labels, researching brands, and supporting companies that commit to using safer
• 11:05
  alternatives can help reduce our exposure to these chemicals.
• 11:09
  Additionally, advocating for stronger regulations and supporting initiatives aimed at
• 11:14
  cleaning up contaminated sites can contribute to reducing the overall impact of PFAS on our
• 11:20
  environment and health.
• 11:24
  In a significant advancement for diabetes and heart disease management, Health Canada has
• 11:29
  approved the first glucagon-like peptide-1 daily pill, known as Rybelsus.
• 11:34
  This oral semaglutide pill is a groundbreaking development, offering an alternative to the
• 11:40
  injectable GLP-1 drugs like Ozempic and Wegovy.
• 11:44
  The approval marks the first time a GLP-1 medication is available in pill form in Canada,
• 11:50
  which could make it more accessible for some patients.
• 11:54
  The pill is specifically approved for adults who have Type 2 diabetes and either have
• 12:00
  cardiovascular disease or are at a high risk for heart disease.
• 12:04
  This approval could potentially benefit a significant portion of the population, as
• 12:09
  cardiovascular disease is a leading cause of death in individuals with diabetes.
• 12:14
  Rybelsus works by improving blood sugar levels in adults with Type 2 diabetes and can also
• 12:19
  reduce the risk of major cardiovascular events, such as heart attacks, strokes, or even death.
• 12:25
  The drug's approval comes after a trial involving 9,650 patients, which showed that
• 12:31
  Rybelsus significantly lowered the risk of cardiovascular events compared to a placebo.
• 12:38
  It's important to note that the effects of GLP-1 medications like Rybelsus diminish once
• 12:43
  patients stop taking them.
• 12:45
  Recent research indicates that individuals who discontinue these medications tend to regain
• 12:51
  weight, which can negate the cardiovascular benefits.
• 12:55
  This highlights the importance of continuous treatment and lifestyle modifications, such as
• 12:59
  diet and exercise, to maintain health benefits.
• 13:04
  While the convenience of a pill might appeal to many, Dr.
• 13:07
  Fahad Razak, an internal medicine physician at St.
• 13:10
  Michael's Hospital, points out that the weekly injectable form of semaglutide is generally
• 13:16
  more effective for weight loss.
• 13:18
  However, for patients who are hesitant about injections, the oral pill could be a viable
• 13:23
  alternative, even if it may require larger doses to achieve similar effectiveness.
• 13:29
  Jennifer Lake, a pharmacist and assistant professor at the University of Toronto,
• 13:34
  explains that because the drug is a peptide, the stomach can break it down when taken
• 13:38
  orally.
• 13:40
  Therefore, larger doses are often necessary to ensure enough of the medication survives the
• 13:45
  digestive process to be effective.
• 13:47
  This is why it was initially administered as an injectable.
• 13:52
  As we continue to advance in medical treatments, options like the GLP-1 daily pill
• 13:58
  offer new hope for individuals managing chronic conditions.
• 14:02
  It's crucial for patients to consult with their healthcare providers to determine the best
• 14:07
  course of treatment based on their individual health needs and preferences.
• 14:12
  That wraps up today's episode of "Morning Medical with Doctor Chow." Thank you for
• 14:16
  joining me as we explored these intriguing topics in health and medicine.
• 14:20
  Stay healthy, and I look forward to catching up with you in our next episode.
• 14:24
  Goodbye for now!
