  Welcome to Morning Medical with Dr.
• 0:02
  Chow, where every day we bring you the latest in medical and health news from around the
• 0:06
  globe, powered by artificial intelligence.
• 0:09
  I'm your host, Dr.
• 0:10
  Chi-Ming Chow, a cardiologist based in Toronto and a Professor of Medicine at the University
• 0:16
  of Toronto.
• 0:17
  Let's dive into today's pressing topics.
• 0:23
  Today, we're talking about a concerning report that highlights a persistent challenge in
• 0:27
  global health: childhood vaccination.
• 0:30
  According to a new report from the World Health Organization and the United Nations Children’s
• 0:35
  Fund, an estimated 14.3 million children worldwide have never received a single dose of
• 0:41
  any vaccine.
• 0:43
  This staggering number underscores the ongoing struggle to protect children from
• 0:48
  vaccine-preventable diseases.
• 0:51
  Despite some improvements, such as 171,000 fewer unvaccinated children last year compared
• 0:56
  to 2023, the report reveals that over 14 million children still remain vulnerable.
• 1:03
  On top of that, 5.7 million children have only partial protection because they might not have
• 1:09
  received all the recommended doses of certain vaccines.
• 1:12
  These figures are troubling, especially considering the diseases that could resurface
• 1:17
  as vaccination rates decline.
• 1:20
  Dr.
• 1:21
  Kate O’Brien, director of the World Health Organization’s Department of Immunization,
• 1:26
  Vaccines and Biologicals, highlights that the global vision is for everyone to benefit from
• 1:32
  lifesaving vaccines.
• 1:34
  Yet, we're facing a 'very stubborn glass ceiling' in terms of reaching more children.
• 1:40
  The challenge is particularly pronounced in conflict zones and fragile countries, where
• 1:45
  children are three times more likely to be unvaccinated.
• 1:49
  The report identifies nine countries, including Nigeria, India, and Sudan, as accounting for
• 1:56
  over half of all children who have never received a vaccine.
• 2:00
  In high-income countries, vaccine hesitancy and distrust in institutions are contributing to a
• 2:06
  resurgence of diseases like measles and polio.
• 2:10
  Misinformation also plays a significant role, leading to outbreaks in communities with low
• 2:15
  vaccination coverage.
• 2:18
  Dr.
• 2:18
  Ephrem Lemango from the United Nations Children’s Fund emphasizes that misinformation
• 2:23
  reflects a broader lack of trust in the systems that deliver vaccines.
• 2:28
  It's critical to address these issues by improving access to vaccines and rebuilding
• 2:33
  trust in health systems.
• 2:36
  The main barrier to vaccination remains access, particularly in dangerous settings where
• 2:41
  government and health services struggle to reach vulnerable populations.
• 2:47
  The report also touches on the impact of funding cuts on global vaccination efforts.
• 2:52
  For instance, the dismantling of the United States Agency for International Development and
• 2:57
  reduced funding for the Global Fund to Fight AIDS, Tuberculosis, and Malaria could
• 3:02
  jeopardize decades of progress.
• 3:04
  The World Health Organization remains committed to partnering with countries to develop local
• 3:10
  solutions and increase investment in vaccination programs.
• 3:14
  Despite these challenges, there are some positive developments.
• 3:18
  For instance, there has been significant improvement in global coverage of the human
• 3:22
  papillomavirus vaccine, particularly in countries like Nigeria and Bangladesh.
• 3:28
  This increase is a bright spot amidst otherwise concerning data.
• 3:33
  Ultimately, the report serves as a call to action.
• 3:37
  Dr.
• 3:38
  Dan Barouch, director of the Center for Virology and Vaccine Research, stresses that 14
• 3:43
  million unvaccinated children are 14 million too many.
• 3:48
  Childhood vaccination is one of the most cost-effective medical interventions, and
• 3:52
  prioritizing these programs should be a global health imperative.
• 3:58
  Let's explore an intriguing connection you might not have considered: sugar and its impact
• 4:03
  on your sex life.
• 4:05
  This topic is gaining attention, and for good reason.
• 4:09
  High blood sugar can affect the sexual health of both men and women, a point underscored by
• 4:13
  Dr.
• 4:14
  Jamin Brahmbhatt, a urologist and robotic surgeon with Orlando Health, and an assistant
• 4:19
  professor at the University of Central Florida’s College of Medicine.
• 4:24
  When we think of sugar, we often picture desserts, not its potential effects on our
• 4:30
  intimate lives.
• 4:31
  Over time, excessive sugar intake can lead to chronic health issues that might interfere with
• 4:37
  some of life's most personal moments.
• 4:39
  In recent years, many have turned to medications like GLP-1 receptor agonists to
• 4:46
  manage blood sugar levels and achieve weight loss.
• 4:49
  These medications have also been noted to improve people's sex lives, likely due to
• 4:54
  better sleep and overall health improvements.
• 4:57
  Dr.
• 4:58
  Brahmbhatt suggests that while these medications are beneficial, there's a broader
• 5:02
  conversation to be had about our sugar intake and its downstream effects on mood, metabolism,
• 5:08
  and sexual health.
• 5:09
  Blood sugar levels, often associated with diabetes, can be checked through various
• 5:13
  methods, including continuous glucose monitors that provide real-time feedback.
• 5:19
  The American Diabetes Association provides guidelines on what constitutes normal,
• 5:24
  prediabetes, and diabetes levels for both fasting and random blood sugar tests.
• 5:30
  A critical test that Dr.
• 5:32
  Brahmbhatt highlights is the hemoglobin A1c test.
• 5:36
  This test measures the average blood sugar level over a two to three-month period and is a
• 5:41
  reliable indicator of how well your body manages glucose over time.
• 5:46
  Elevated A1c levels can lead to poor recovery and complications after surgeries, stressing
• 5:52
  the importance of maintaining healthy glucose levels.
• 5:56
  High blood sugar can have significant repercussions on sexual health.
• 6:00
  In men, it can damage nerves and blood vessels necessary for erections, potentially leading to
• 6:06
  erectile dysfunction.
• 6:08
  It can also lower testosterone levels, reducing libido and energy.
• 6:13
  For some men, changes in sexual performance might be the first indication of an underlying
• 6:18
  blood sugar issue.
• 6:20
  Women are not immune to these effects.
• 6:23
  High blood sugar can lead to reduced blood flow and hormone imbalances, causing vaginal
• 6:28
  dryness, painful intercourse, or difficulties with orgasm.
• 6:33
  It can also increase the risk of urinary tract infections, making intimacy less appealing.
• 6:39
  Often, these symptoms are mistakenly attributed to aging or stress, rather than blood sugar
• 6:45
  levels.
• 6:47
  Treatment for high blood sugar traditionally starts with oral medications, such as
• 6:52
  metformin, which helps lower glucose by reducing sugar production in the liver.
• 6:57
  For cases where oral medications are insufficient, injectable medications like
• 7:01
  insulin or GLP-1 receptor agonists may be necessary.
• 7:06
  These newer medications have gained popularity not only for managing type 2 diabetes but also
• 7:12
  for aiding weight loss.
• 7:15
  Recent research suggests that GLP-1 drugs may also help normalize testosterone levels in men
• 7:20
  with obesity or type 2 diabetes.
• 7:22
  Although more research is needed, these findings indicate the far-reaching benefits of
• 7:26
  managing blood sugar and weight on overall health, including sexual function.
• 7:32
  Before immediately resorting to medication, consider the power of lifestyle changes.
• 7:36
  Regular exercise can improve insulin sensitivity, promote weight loss, and enhance
• 7:41
  sexual function by boosting blood flow and hormone balance.
• 7:45
  A balanced diet rich in whole foods and lean protein can stabilize blood sugar and reduce
• 7:50
  inflammation.
• 7:51
  Other factors like good sleep hygiene, reduced alcohol consumption, and stress management also
• 7:56
  play crucial roles.
• 7:59
  So, if you're pondering whether to start a new medication or change your lifestyle, perhaps
• 8:04
  reaching for your gym bag might be the better first step.
• 8:08
  It could transform not only your lab results but also how you feel about yourself and your
• 8:13
  life.
• 8:14
  And as Dr.
• 8:15
  Brahmbhatt reminds us, the next time you indulge in a sweet treat, consider its impact
• 8:21
  on your energy, heart, and sexual health.
• 8:25
  Today, we're exploring a crucial topic that ties directly into our cognitive well-being:
• 8:30
  the foods we consume and their impact on brain health.
• 8:34
  Dr.
• 8:34
  Raveesh Sunkara, a renowned Board Certified Neurosurgeon based in Hyderabad, has
• 8:40
  highlighted three common foods that pose significant risks to our brain health.
• 8:44
  Let's delve into what these foods are and why they might be damaging.
• 8:49
  First on Dr.
• 8:50
  Sunkara's list are foods high in trans fats.
• 8:53
  Now, if you enjoy deep-fried foods or indulge in packaged snacks, it might be time to
• 8:58
  reconsider those choices.
• 9:00
  Trans fats, often listed as 'partially hydrogenated oils' on ingredient labels, are
• 9:06
  prevalent in many of our favorite treats, from chips to pastries.
• 9:10
  Dr.
• 9:10
  Sunkara warns that these fats can cause inflammation in the brain, leading to long-term
• 9:15
  health issues.
• 9:17
  To minimize your intake of trans fats, focus on whole, unprocessed foods.
• 9:23
  Carefully checking nutrition labels can also aid in avoiding these harmful fats.
• 9:28
  Additionally, cooking with healthier oils, such as olive or avocado oil, can help reduce
• 9:34
  exposure.
• 9:36
  Next up, sugary drinks.
• 9:38
  These beverages are notorious for being sources of empty calories, filled with chemicals that
• 9:44
  are detrimental to our health.
• 9:46
  Dr.
• 9:47
  Sunkara points out that consuming high-sugar drinks can lead to blood glucose spikes, which
• 9:52
  over time, may result in brain fatigue and even shrinkage.
• 9:56
  This is particularly concerning as studies have linked excessive sugar consumption to reduced
• 10:01
  brain volume, especially in areas crucial for memory and decision-making.
• 10:05
  To combat these effects, consider swapping sugary drinks with water, herbal teas, or
• 10:11
  unsweetened alternatives.
• 10:13
  Lastly, Dr.
• 10:15
  Sunkara highlights the dangers of ultra-processed foods.
• 10:18
  These include sugary drinks, packaged snacks, sweets, ice cream, packaged breads, processed
• 10:24
  meats, and ready-to-heat products.
• 10:26
  Ultra-processed foods are notorious for causing gut issues, which in turn disrupt the gut-brain
• 10:32
  axis.
• 10:34
  An unhealthy gut can lead to inflammation and impaired neurotransmitter function, increasing
• 10:39
  the risk of anxiety, depression, and cognitive decline.
• 10:44
  Instead, a diet rich in whole foods like fruits, vegetables, and lean proteins can
• 10:49
  promote a healthy microbiome and support cognitive health.
• 10:54
  Dr.
• 10:55
  Sunkara's insights emphasize the profound impact our dietary choices have on our brain
• 11:00
  health.
• 11:02
  Prioritizing whole, unprocessed foods is crucial for maintaining cognitive well-being.
• 11:08
  So, the next time you're reaching for a snack, consider its long-term effects on your brain.
• 11:13
  Making mindful food choices today can lead to better brain health tomorrow.
• 11:19
  Today's discussion revolves around an important topic that affects a significant part of the
• 11:24
  population: how obesity may impact vitamin D supplementation.
• 11:29
  Maintaining adequate levels of serum vitamin D is crucial, especially for individuals with
• 11:34
  osteoporosis, as it helps preserve bone strength and prevent falls.
• 11:40
  However, when it comes to people with obesity, managing vitamin D levels can be quite complex.
• 11:47
  Dr.
• 11:47
  Bess Dawson-Hughes from the Jean Mayer United States Department of Agriculture Human
• 11:52
  Nutrition Research Center on Aging at Tufts University shared insights at the American
• 11:57
  Association of Clinical Endocrinology annual meeting.
• 12:01
  She emphasized that the management of vitamin D in patients with obesity differs from that in
• 12:06
  non-obese patients.
• 12:08
  Often, serum 25-hydroxyvitamin D levels are low in individuals with obesity due to several
• 12:15
  factors, including insufficient dietary intake, reduced sun exposure, diminished enzyme
• 12:21
  activity, and changes in the gut microbiome that affect vitamin D absorption.
• 12:26
  Although obesity is often linked to higher bone density, this does not necessarily mean there
• 12:32
  is a lower fracture risk.
• 12:34
  In fact, the Endocrine Society's 2024 clinical practice guidelines highlight that
• 12:40
  postmenopausal females with obesity have a significantly higher risk of fractures.
• 12:45
  This discrepancy underscores the need for careful management of vitamin D levels in this
• 12:50
  population.
• 12:52
  For those with osteoporosis, maintaining a serum 25-hydroxyvitamin D level of 30 nanograms
• 12:58
  per milliliter is recommended, with a daily supplement of 1,000 to 2,000 international
• 13:03
  units of vitamin D3 if necessary.
• 13:06
  However, people with obesity may require higher doses to reach the same target levels.
• 13:12
  Dr.
• 13:14
  Dawson-Hughes pointed out that the same dose given to a lean individual and one with obesity
• 13:20
  would not yield the same results.
• 13:23
  Therefore, it's important to adjust the supplementation accordingly.
• 13:28
  While there is no consensus on a standardized dose for vitamin D supplementation in
• 13:33
  individuals with obesity, some researchers suggest doses be two to three times higher for
• 13:38
  these patients.
• 13:39
  In certain studies, people with obesity needed a 40% higher vitamin D intake than those of
• 13:45
  normal weight to achieve similar serum levels.
• 13:48
  Dr.
• 13:49
  Dawson-Hughes recommends using a vitamin D dosing formula that considers body weight to
• 13:54
  tailor the approach for each patient.
• 13:57
  It's also important to note that obesity may delay reaching a steady state of vitamin D
• 14:03
  after beginning supplementation.
• 14:06
  The expected time to reach a steady state is about two and a half to three months, but this
• 14:12
  may not hold true for individuals with obesity.
• 14:15
  In studies, participants with normal weight reached a plateau in serum levels within six
• 14:21
  months, while those with obesity continued to see rising levels for up to twelve months.
• 14:25
  Dr.
• 14:27
  Dawson-Hughes cautions against increasing doses too quickly if levels are not steady at three
• 14:32
  months, as excessively high doses can increase the risk of falls and fractures.
• 14:38
  A more refined understanding of how serum 25-hydroxyvitamin D responds to supplementation
• 14:43
  in people with obesity is needed.
• 14:46
  The goal is to develop weight category-specific recommendations in the future.
• 14:52
  As wildfires continue to impact vast regions, the air quality in many areas has been a
• 14:58
  growing concern.
• 14:59
  Environment Canada plays a pivotal role in helping Canadians understand and manage these
• 15:05
  risks through their Air Quality Health Index.
• 15:08
  This index provides a clear and accessible way to gauge the air quality and make informed
• 15:13
  decisions about outdoor activities.
• 15:16
  The Air Quality Health Index is available on Environment Canada's website, and it
• 15:21
  categorizes air quality into four risk levels.
• 15:25
  A rating of one to three indicates low risk, where it's generally safe for everyone to be
• 15:31
  outdoors.
• 15:32
  A rating between four and six signals moderate risk, suggesting that those with respiratory
• 15:38
  issues or other vulnerabilities should consider reducing their outdoor activities if they
• 15:42
  experience symptoms like coughing.
• 15:45
  When the index shows a rating of seven to ten, it's classified as high risk.
• 15:51
  At this level, vulnerable groups, including individuals with heart and lung conditions,
• 15:56
  young children, and the elderly, should minimize outdoor exertion.
• 16:01
  The general population is also advised to reschedule strenuous activities if they notice
• 16:06
  any symptoms such as throat irritation.
• 16:09
  A rating above ten is labeled as very high risk.
• 16:13
  At this stage, it's recommended that everyone, regardless of their health status, reduce or
• 16:18
  avoid outdoor activities.
• 16:20
  Those particularly at risk should remain indoors to protect their health.
• 16:25
  These ratings are not static; they can fluctuate throughout the day and vary from one
• 16:31
  community to another.
• 16:32
  This variability underscores the importance of regularly checking the Air Quality Health
• 16:37
  Index, especially during wildfire season, to stay updated on current conditions in your
• 16:42
  area.
• 16:44
  For individuals at greater risk, such as those with asthma, chronic obstructive pulmonary
• 16:49
  disease, or heart disease, as well as infants, pregnant individuals, and older adults, it's
• 16:54
  crucial to adhere to these guidelines to minimize health risks.
• 16:59
  Environment Canada, in collaboration with Health Canada, provides these recommendations
• 17:03
  to help protect public health during periods of poor air quality.
• 17:08
  As we wrap up today's episode, remember that staying informed about air quality is vital for
• 17:14
  maintaining good health, particularly in times of increased wildfire activity.
• 17:19
  Make sure to check your local air quality readings regularly and take appropriate actions
• 17:23
  to safeguard your well-being.
• 17:26
  Thank you for tuning in to Morning Medical with Dr.
• 17:29
  Chow.
