  Good morning, everyone, and welcome to another episode of Morning Medical with Dr.
• 0:06
  Chow.
• 0:06
  I'm Dr.
• 0:08
  Chi-Ming Chow, your host for this daily podcast where we delve into the latest in medical and
• 0:14
  health news from around the globe.
• 0:17
  Today, we're diving into a crucial development in the fight against microplastics, a topic
• 0:23
  that's garnering significant attention due to its implications for public health.
• 0:31
  Recently, Robert F.
• 0:33
  Kennedy Jr., the Health and Human Services Secretary, alongside Lee Zeldin, the
• 0:38
  Environmental Protection Agency Administrator, have declared what they call a 'war' on
• 0:43
  microplastics.
• 0:45
  These tiny plastic particles, often less than five millimeters in size, have been found to
• 0:50
  persist in our environment for hundreds or even thousands of years.
• 0:54
  More worryingly, they're accumulating in our bodies, potentially wreaking havoc on our
• 0:58
  health.
• 1:00
  In a groundbreaking move, the Environmental Protection Agency is now including
• 1:04
  microplastics and pharmaceuticals in its Contaminant Candidate List for drinking water.
• 1:10
  This is a significant step as it prioritizes funding and paves the way for possible future
• 1:15
  regulations.
• 1:17
  This decision marks the first time such materials have been acknowledged in this
• 1:21
  capacity, highlighting the growing concern over their impact.
• 1:25
  The Health and Human Services Department is launching an initiative called the Systematic
• 1:29
  Targeting of Microplastics, or STOMP, which aims to study how these particles accumulate in
• 1:34
  the body.
• 1:36
  This research is crucial because, as of now, the science doesn't clearly differentiate the
• 1:40
  impacts of various types of plastics.
• 1:43
  By identifying which types are most harmful, we could potentially eliminate them and replace
• 1:48
  them with safer alternatives.
• 1:50
  Robert F.
• 1:51
  Kennedy Jr.
• 1:53
  emphasized the urgency of addressing this issue, citing emerging science that links
• 1:58
  microplastics to inflammation, oxidative stress, and endocrine disruption, which can
• 2:04
  interfere with fertility.
• 2:07
  There's also growing evidence suggesting these particles might increase the risk of heart
• 2:11
  attacks, strokes, and neurodegenerative diseases when present at the cellular level.
• 2:17
  The parallels to past public health initiatives, like the reduction of lead
• 2:22
  exposure in the 1970s, are striking.
• 2:26
  Back then, actions were taken even before all the research was complete because the potential
• 2:32
  dangers were too significant to ignore.
• 2:35
  It's a lesson in proactive public health intervention that resonates with the current
• 2:40
  push against microplastics.
• 2:43
  Kennedy also pointed out the role of big businesses in this environmental issue, urging
• 2:48
  them to take responsibility for their contributions.
• 2:51
  He likened it to a simple lesson from kindergarten: clean up after yourself.
• 2:55
  It's an appeal for corporate accountability in tackling both microplastics and pharmaceutical
• 3:00
  contaminants in the environment.
• 3:03
  Lee Zeldin, the Environmental Protection Agency Administrator, stressed the importance of
• 3:08
  education and transparency.
• 3:11
  He cautions against a one-size-fits-all federal approach and calls for 'gold-standard' science
• 3:16
  to guide regulations.
• 3:18
  Zeldin and Kennedy, working under President Trump's Make America Healthy Again agenda,
• 3:23
  showcase a bipartisan effort to confront this ever-growing problem.
• 3:28
  As we see these efforts unfold, it's clear that addressing microplastics is not just an
• 3:34
  environmental issue but a pressing public health concern.
• 3:38
  The collaboration between the Health and Human Services and the Environmental Protection
• 3:42
  Agency marks a pivotal moment in tackling this challenge.
• 3:47
  Stay tuned as we continue to follow developments in this critical area of health
• 3:51
  and environmental science.
• 3:55
  Today, we're exploring a fascinating study that sheds light on predicting stroke risk years
• 4:00
  after a person experiences a minor stroke, also known as a transient ischemic attack.
• 4:07
  This research, published in the journal Circulation by the American Heart Association,
• 4:12
  delves into the long-term risks faced by individuals who have had these so-called
• 4:18
  'mini-strokes.'
• 4:19
  The study builds on previous findings from the PERSIST study, which highlighted that the risk
• 4:24
  of stroke doesn't just vanish after the typical ninety-day monitoring period post-event.
• 4:30
  Instead, the risk persists and can remain elevated for at least a decade.
• 4:36
  This is a crucial insight for both patients and healthcare providers.
• 4:40
  The researchers conducted a systemic review that included twenty-eight observational
• 4:45
  studies with more than eighty-six thousand participants.
• 4:49
  These individuals were followed for at least one year after experiencing a minor stroke.
• 4:54
  The median age of the participants was sixty-nine, and fifty-seven percent were men.
• 5:00
  From this comprehensive review, five key factors emerged as predictors of stroke
• 5:05
  recurrence.
• 5:06
  Firstly, high blood pressure, or hypertension, stands out as the most critical modifiable risk
• 5:12
  factor.
• 5:13
  It's well-recognized by the American Stroke Association as a major contributor to stroke
• 5:18
  risk.
• 5:19
  Secondly, smoking is another significant factor, roughly doubling the likelihood of a
• 5:25
  repeat stroke.
• 5:27
  The study also identified three specific types of strokes as having a high risk of recurrence.
• 5:33
  Cardioembolic stroke, which occurs when a blood clot forms in the heart and travels to the
• 5:38
  brain, is one such type.
• 5:41
  This stroke subtype is particularly concerning due to its high recurrence risk.
• 5:46
  Then there's large-artery atherosclerotic stroke, which involves plaque buildup in major
• 5:51
  arteries, either reducing blood flow or sending clots to the brain.
• 5:56
  Lastly, small-vessel disease, often linked to chronic hypertension and aging, also poses a
• 6:02
  significant risk, although to a lesser extent than the first two types.
• 6:07
  Older age was another factor associated with an increased risk of having another stroke.
• 6:13
  The findings from this study are immensely valuable as they can guide doctors in
• 6:18
  identifying patients who are at a long-term risk of stroke.
• 6:23
  This allows for more vigilant monitoring and tailored interventions to mitigate these risks.
• 6:28
  Dr.
• 6:29
  Bibhu D.
• 6:30
  Mohanty, a cardiovascular sciences associate professor at the University of South Florida's
• 6:36
  Morsani College of Medicine, although not involved in the research, emphasized the
• 6:41
  importance of identifying these risk factors.
• 6:44
  He noted that recognizing these factors is just the first step, and the next is to determine
• 6:49
  actionable interventions to address them.
• 6:52
  Dr.
• 6:53
  Mohanty also highlighted the overlap between brain health and heart health, suggesting that
• 6:58
  collaboration between cardiologists and neurologists is essential for comprehensive
• 7:02
  patient care.
• 7:04
  This interdisciplinary approach could be key in effectively managing patients with a history of
• 7:09
  stroke or those at risk.
• 7:12
  Today, we'll be delving into the world of beauty and youth as touted by social media
• 7:17
  influencers, particularly focusing on injectable peptides.
• 7:21
  These substances are being promoted as the latest miracle solutions for muscle building
• 7:26
  and anti-aging.
• 7:27
  However, there's a significant gap between these claims and scientific evidence.
• 7:33
  Historically, humans have gone to great lengths in the search for eternal youth, from using
• 7:37
  crocodile dung to raw meat facials.
• 7:40
  Nowadays, influencers are suggesting that injectable peptides are the answer.
• 7:46
  But, the scientific community remains skeptical.
• 7:50
  Injectable peptides are short chains of amino acids, the building blocks of proteins, that
• 7:55
  occur naturally in the body.
• 7:57
  They play a role in regulating hormones, digestion, and muscle growth.
• 8:02
  While some peptides, like insulin and GLP-1s such as Ozempic, are well-researched and used
• 8:09
  in medicine, the ones promoted by influencers lack such backing.
• 8:14
  These peptides are often sold in a legal gray area, marketed for research purposes but
• 8:19
  acquired for unapproved uses.
• 8:21
  Health Canada has issued warnings about purchasing these unregulated drugs online, and
• 8:26
  globally, many are banned for professional athletes by the World Anti-Doping Agency.
• 8:32
  Despite the lack of large-scale human trials, certain online communities and influencers,
• 8:38
  including those in the 'manosphere' and 'looksmaxxing' movements, continue to promote
• 8:42
  these peptides.
• 8:43
  They claim benefits like faster muscle growth and anti-aging effects, but these are not
• 8:48
  supported by scientific evidence.
• 8:51
  Experts like Stuart Phillips, the Canada Research Chair in Skeletal Muscle Health,
• 8:56
  emphasize the lack of evidence supporting the use of unregulated injectable peptides.
• 9:02
  He points out that there are no efficacy or safety trials to justify their widespread use.
• 9:09
  Tim Caulfield, a Canada Research Chair specializing in the commercialization of
• 9:13
  medicine, describes this trend as 'science-ploitation.' He explains how
• 9:18
  influencers exploit genuine areas of research to market unproven treatments, similar to past
• 9:24
  trends with unregulated stem cell products.
• 9:28
  The risks associated with these peptides are significant.
• 9:31
  Since their manufacturing is largely unregulated, there’s no assurance of sterility,
• 9:36
  posing potential infection risks like sepsis.
• 9:39
  Moreover, without proper studies, we don’t know the right dosages or how these peptides might
• 9:45
  interact with the body.
• 9:47
  Caulfield also warns that some peptides, such as BPC-157, might speed up tissue repair,
• 9:54
  potentially encouraging the growth of cancerous cells.
• 9:57
  This lack of understanding and regulation makes using these peptides risky.
• 10:03
  Ultimately, the advice from experts is clear: avoid ordering unproven pharmaceuticals online.
• 10:10
  Instead, focus on proven methods for maintaining health and youth, like regular
• 10:15
  physical activity, a balanced diet, and good sleep habits.
• 10:20
  These may not be as exciting as a quick fix, but they are backed by science and have stood
• 10:25
  the test of time.
• 10:28
  Now, onto our final segment for today, we're turning our attention to a study that reveals a
• 10:33
  straightforward eating habit which might aid in weight loss.
• 10:37
  This research, published in the journal Health Psychology, suggests that sticking to the same
• 10:43
  meals more frequently could be beneficial for those looking to shed pounds.
• 10:48
  The study observed 112 overweight or obese adults who participated in a twelve-week
• 10:53
  weight-loss program.
• 10:54
  These individuals tracked their meals using an app and weighed themselves daily.
• 10:59
  The researchers focused on two main aspects of 'routinized' eating: how much participants'
• 11:04
  daily calorie intake varied and how often they repeated the same meals and snacks.
• 11:10
  The findings showed that participants who incorporated more repeated foods into their
• 11:15
  diets lost an average of five point nine percent of their body weight.
• 11:20
  In contrast, those with more varied eating patterns lost about four point three percent.
• 11:26
  Additionally, those who kept their daily calorie intake more consistent also experienced
• 11:31
  greater weight loss.
• 11:33
  Charlotte Hagerman, the lead author from the Oregon Research Institute, highlighted that
• 11:38
  creating routines around eating can reduce the mental burden of making food choices, making
• 11:44
  healthy decisions more automatic.
• 11:47
  This aligns with the experiences of nutrition experts like Liza Baker, who noted that repeat
• 11:52
  meals can alleviate decision fatigue and support sustainable wellness journeys.
• 11:58
  However, it's important to note that the study was observational, meaning it found an
• 12:03
  association rather than proving causation.
• 12:07
  Future research is needed to determine if a repetitive diet should be actively recommended
• 12:13
  for weight loss.
• 12:15
  There are potential downsides to consider, such as the risk of nutritional imbalances or
• 12:20
  triggering perfectionism if the meal plans aren't well-balanced.
• 12:24
  As we wrap up today's episode, remember that while the allure of quick fixes is tempting,
• 12:30
  sustainable health often comes down to balance and consistency.
• 12:34
  Whether it's addressing microplastics, managing stroke risks, or exploring weight-loss
• 12:39
  strategies, informed choices backed by science are crucial.
