  Hello, and welcome to Morning Medical with Dr.
• 0:02
  Chow, where we delve into the latest medical and health news from around the globe.
• 0:07
  I'm your host, Dr.
• 0:09
  Chi-Ming Chow, a cardiologist and professor of medicine at the University of Toronto.
• 0:15
  Today, we're going to talk about a subject that's been making waves in the health
• 0:19
  community recently: the rise in walking pneumonia cases in Canada.
• 0:26
  Walking pneumonia, or Mycoplasma pneumoniae, is a mild bacterial infection that primarily
• 0:33
  affects children and teenagers.
• 0:35
  It's often referred to as 'walking pneumonia' because those infected are generally not as
• 0:41
  severely ill as those with other types of pneumonia.
• 0:45
  You might feel under the weather, but not sick enough to be bedridden or hospitalized.
• 0:50
  Dr.
• 0:51
  Isaac Bogoch, an infectious disease specialist at Toronto General Hospital, explains that
• 0:57
  while many people can go about their daily lives feeling just a bit unwell, it can still
• 1:03
  make some individuals quite sick.
• 1:06
  Recently, pediatric hospitals across Canada and the United States have reported an uptick in
• 1:12
  cases.
• 1:12
  The United States Centers for Disease Control and Prevention noted a rise in Mycoplasma
• 1:18
  pneumoniae infections, especially among young children, starting in late spring, with case
• 1:24
  counts remaining high.
• 1:26
  Although Canada doesn't track walking pneumonia cases officially, doctors have observed an
• 1:31
  increase anecdotally.
• 1:35
  Dr.
• 1:36
  Earl Rubin, a pediatric infectious disease specialist at the Montreal Children's Hospital,
• 1:41
  mentioned that since the summer, there have been more patients admitted with positive
• 1:45
  tests.
• 1:47
  In Halifax, the IWK Health Centre reported a significant increase, with 113 cases this year
• 1:55
  compared to just 11 last year.
• 1:57
  The British Columbia Centre for Disease Control also reported a rise in respiratory infections
• 2:02
  due to Mycoplasma pneumoniae, particularly among people under 20.
• 2:07
  This trend is being closely monitored across the country.
• 2:11
  So, what causes this infection?
• 2:14
  Mycoplasma pneumoniae is a bacterial infection that spreads through the air when an infected
• 2:20
  person coughs or sneezes.
• 2:22
  While it can affect people of all ages, it's most common in children aged five to seventeen
• 2:27
  and young adults.
• 2:28
  Interestingly, there's been a notable increase in cases among children aged two to four, a
• 2:33
  group not typically associated with this infection.
• 2:37
  The symptoms usually resemble those of a chest cold, including fever, cough, and fatigue.
• 2:44
  In about a quarter of cases, the infection progresses to pneumonia, involving the lungs.
• 2:50
  Some patients might also experience nausea, vomiting, or diarrhea.
• 2:56
  Diagnosis is often based on clinical signs and symptoms without waiting for lab tests, as most
• 3:02
  people recover on their own.
• 3:05
  The treatment for Mycoplasma pneumoniae involves antibiotics, with azithromycin being a
• 3:10
  common choice.
• 3:11
  The bacteria are considered atypical due to their lack of a cell wall, which makes some
• 3:17
  common pneumonia antibiotics ineffective.
• 3:21
  Why are we seeing a rise in cases now?
• 3:24
  One hypothesis is that after the COVID-19 pandemic, there are more people who haven't
• 3:30
  been exposed to this bacteria and are therefore more susceptible.
• 3:34
  Combine that with its infectious nature, and it's no surprise that cases are climbing.
• 3:41
  There's no indication that the bacteria itself has changed.
• 3:45
  Most children with walking pneumonia can be treated at home with plenty of fluids, rest,
• 3:49
  and medications to reduce fever.
• 3:52
  However, if a child is experiencing more severe symptoms like respiratory distress or wheezing,
• 3:58
  particularly if they have existing asthma, it's crucial to seek medical attention.
• 4:03
  Prevention remains key.
• 4:05
  Health officials recommend staying up to date with vaccinations, including for COVID-19 and
• 4:11
  influenza, and practicing good hygiene, such as regular handwashing and wearing masks in
• 4:17
  crowded indoor spaces.
• 4:19
  While vaccines won't directly prevent Mycoplasma pneumoniae, they can reduce the risk
• 4:24
  of secondary infections and more severe illness.
• 4:28
  Quitting smoking is one of the best decisions you can make for your health, but many people
• 4:33
  wonder how long it takes for the health risks associated with smoking to return to normal.
• 4:39
  A recent study from researchers in South Korea offers some insights into this question.
• 4:46
  The study, published in the Journal of the American Medical Association, examined the
• 4:50
  health data of over 100,000 former smokers and more than four million people who have never
• 4:56
  smoked.
• 4:58
  It found that the risk of cardiovascular diseases such as heart attack and stroke
• 5:02
  decreases significantly after quitting smoking, but the timeline for this reduction varies,
• 5:08
  particularly for heavy smokers.
• 5:11
  For individuals who smoked heavily for at least eight years, the study suggests it can take up
• 5:16
  to 25 years for their cardiovascular risk to align with that of someone who has never
• 5:22
  smoked.
• 5:23
  This finding underscores the dose-dependent relationship between smoking and cardiovascular
• 5:29
  risk.
• 5:30
  In other words, the more you smoke, the longer it takes for your health risks to normalize
• 5:34
  after quitting.
• 5:36
  On the other hand, those who were light smokers may see their risk for cardiovascular disease
• 5:41
  drop to normal levels much sooner after quitting.
• 5:44
  The study highlights the importance of quitting smoking as soon as possible to minimize
• 5:48
  long-term health risks.
• 5:51
  Smoking is a major cause of cardiovascular diseases, contributing to at least 15,000 heart
• 5:56
  disease deaths annually in the United Kingdom alone, according to the British Heart
• 6:01
  Foundation.
• 6:02
  The harmful effects of smoking on the heart are well-documented, with tobacco containing over
• 6:08
  7,000 chemicals, including tar and nicotine, which damage blood vessels and increase heart
• 6:13
  rate and blood pressure.
• 6:15
  The study's authors emphasize that heavy former smokers should be considered at a similar
• 6:21
  cardiovascular disease risk as current smokers when it comes to assessing their health.
• 6:27
  This highlights the importance of regular health check-ups and monitoring for those who
• 6:33
  have a history of heavy smoking.
• 6:36
  The research adds to a growing body of evidence that illustrates the long-term benefits of
• 6:41
  quitting smoking.
• 6:42
  While the journey to risk reduction can be long, the positive impacts on overall health
• 6:47
  and longevity are substantial.
• 6:50
  This study serves as a reminder that it's never too late to quit and start the road to
• 6:54
  recovery.
• 6:56
  Today, we're diving into the impact of smoking and vaping on fertility.
• 7:01
  It's a topic that's been gaining attention, and for good reason.
• 7:04
  Smoking tobacco products, including vaping, has been shown to have significant negative effects
• 7:10
  on fertility.
• 7:11
  This is especially critical for those planning to start a family or who are concerned about
• 7:16
  their reproductive health.
• 7:18
  Dr.
• 7:19
  Courtney D.
• 7:21
  Lynch, a specialist in maternal fetal medicine at The Ohio State University College of
• 7:26
  Medicine, emphasizes that smoking has a well-documented adverse impact on both natural
• 7:32
  and medically assisted conception.
• 7:34
  She notes that while human data on vaping and fertility are limited, animal studies suggest
• 7:40
  vaping is problematic as well.
• 7:42
  Nicotine, a primary component in both cigarettes and vapes, is a known reproductive
• 7:47
  and developmental toxicant.
• 7:51
  Smoking and vaping expose the embryo to harmful compounds, which can impair fertility in
• 7:56
  several ways.
• 7:58
  Nicotine affects the functioning of the cilia in the fallopian tubes, which are crucial for
• 8:03
  transporting the embryo to the uterus.
• 8:06
  This disruption can increase the risk of ectopic pregnancies, where the embryo implants
• 8:11
  outside the uterus, posing serious health risks.
• 8:15
  Moreover, smoking and vaping can alter gene expression, potentially leading to long-term
• 8:20
  reproductive issues.
• 8:22
  Dr.
• 8:22
  Lynch highlights that the proper transport of the embryo is essential for a successful
• 8:27
  pregnancy, and nicotine's interference in this process can be detrimental.
• 8:33
  Dr.
• 8:33
  Theodore Wagener, director of the Center for Tobacco Research at The Ohio State University
• 8:38
  Comprehensive Cancer Center, supports these findings, citing scientific literature that
• 8:44
  clearly shows smoking negatively affects fertility.
• 8:47
  In women, smoking damages egg quality and quantity, accelerates egg loss, and can lead to
• 8:54
  earlier menopause.
• 8:55
  It also increases the risk of fertility treatment failures, miscarriage, and menstrual
• 9:00
  irregularities.
• 9:02
  For men, smoking can reduce both sperm count and quality.
• 9:08
  It can damage sperm DNA and disrupt testosterone production, potentially leading to
• 9:13
  erectile dysfunction.
• 9:15
  While the data on vaping is less extensive, it is believed to have similar negative impacts on
• 9:21
  hormone levels and DNA integrity, contributing to fertility issues.
• 9:26
  Both Dr.
• 9:27
  Lynch and Dr.
• 9:28
  Wagener agree that quitting all nicotine and tobacco products is crucial for improving
• 9:33
  fertility.
• 9:34
  Limiting exposure to environmental smoke is also important for reproductive health.
• 9:39
  While the journey to quitting can be challenging, the benefits for fertility and
• 9:43
  overall health are substantial.
• 9:46
  As we adjust our clocks for daylight saving time, many of us might find getting out of bed
• 9:51
  more challenging than usual.
• 9:52
  This change can disrupt our sleep patterns, but for a significant number of adults in the
• 9:57
  United States, sleep deprivation is a persistent issue beyond the biannual clock
• 10:02
  adjustment.
• 10:03
  Chronic sleep deprivation is not just about feeling tired; it has substantial implications
• 10:08
  for both physical and mental health.
• 10:12
  Research has shown that consistently poor sleep quality can increase the risk of developing
• 10:17
  cardiovascular disease, high blood pressure, and metabolic disorders.
• 10:22
  Additionally, it can weaken your immune system, making you more susceptible to infections.
• 10:28
  The mental health implications are just as serious, with long-term sleep deprivation
• 10:33
  linked to conditions such as depression, anxiety, and other mental health disorders.
• 10:40
  On the flip side, getting sufficient sleep can have a range of positive effects.
• 10:45
  It helps reduce stress, enhances attention and focus, and even strengthens our immune
• 10:50
  defenses.
• 10:51
  The benefits of adequate sleep extend beyond just feeling rested; it plays a crucial role in
• 10:56
  overall health and well-being.
• 10:59
  Interestingly, you do not need to miss out on a significant amount of sleep to experience its
• 11:05
  negative effects.
• 11:07
  Experts suggest that even a consistent shortfall of just 15 minutes per night can lead
• 11:12
  to sleep deprivation.
• 11:14
  Such a minor deficit, when accumulated over time, can have significant health consequences.
• 11:21
  So, how prevalent is sleep deprivation?
• 11:24
  According to the Centers for Disease Control and Prevention, adults should aim for seven to
• 11:29
  nine hours of sleep each night.
• 11:31
  However, about one in three adults in the United States falls short of this
• 11:36
  recommendation, routinely getting less than seven hours per night.
• 11:41
  This trend has been increasing over recent decades, partly due to longer working hours and
• 11:46
  the pervasive use of electronic devices like computers and phones that emit blue light.
• 11:52
  Blue light, similar to sunlight, triggers brain receptors that keep us awake.
• 11:58
  Dr.
• 12:02
  Charlene Gamaldo, a professor of neurology at Johns Hopkins University School of Medicine,
• 12:07
  points out that as we become more connected and reliant on technology, the issue of sleep
• 12:13
  deprivation becomes more pressing.
• 12:16
  Our modern lifestyle, with its constant connectivity, poses a significant challenge to
• 12:21
  maintaining healthy sleep patterns.
• 12:25
  The end of Daylight Saving Time can bring about a number of changes that affect our health,
• 12:30
  both physically and mentally.
• 12:33
  According to experts, this biannual shift can have a significant impact on our body's
• 12:38
  exposure to daily sunlight, as well as on the levels of serotonin and melatonin, which are
• 12:44
  crucial for our mood and sleep cycles.
• 12:47
  Kathryn Emery, a licensed professional counselor at Thriveworks in Cedar Park,
• 12:52
  highlights that while the shift might be minimal for some, others may experience more
• 12:57
  profound effects.
• 13:00
  One of the most noticeable losses during this transition is sunlight.
• 13:06
  Although we may not always be aware of its importance, sunlight plays a crucial role in
• 13:11
  our daily lives.
• 13:13
  It helps regulate serotonin levels, often referred to as the 'happy chemical,' which can
• 13:19
  significantly influence our mood.
• 13:22
  Emery explains that without sufficient sunlight, our serotonin levels may drop,
• 13:28
  potentially affecting our mood negatively.
• 13:31
  Serotonin is a precursor to melatonin, an essential hormone that regulates sleep.
• 13:37
  The reduction in sunlight exposure can, therefore, also impact our sleep quality.
• 13:42
  This is why some people might find themselves feeling sleepier or more tired as they adjust
• 13:47
  to the new time.
• 13:49
  Beyond the biological implications, there are social impacts as well.
• 13:53
  Shorter daylight hours mean less time for outdoor activities and social interactions,
• 13:59
  such as playing sports, meeting friends, or simply enjoying a walk.
• 14:03
  These changes can have further repercussions on our mental and physical health, as social
• 14:08
  interactions are a key component of well-being.
• 14:12
  Some individuals may experience mood disturbances or irritability, while others
• 14:17
  might face more severe symptoms like early signs of depression as they adjust to the time
• 14:22
  change.
• 14:24
  Emery notes that this period can also affect the heart and vascular systems, reflecting the
• 14:30
  broader physical impacts of this transition.
• 14:33
  To help mitigate these effects, Emery suggests two key strategies: maximizing sunlight
• 14:39
  exposure and adjusting sleep schedules in advance.
• 14:43
  Spending a few minutes outside each day can help reset your body’s circadian rhythms.
• 14:49
  Additionally, gradually adjusting your sleep schedule before the time change can make the
• 14:54
  transition smoother.
• 14:57
  Emery also points out that while most people will experience only minor effects, those with
• 15:02
  conditions like seasonal affective disorder might find the transition more challenging.
• 15:08
  It's important to be aware of these potential impacts and seek support if needed.
• 15:13
  Remember, resources like the 988 Lifeline are available for immediate help during any mental
• 15:19
  health struggles.
• 15:21
  Our final topic for today takes us to the realm of education and technology's place within it.
• 15:27
  A few months ago, Ontario implemented a cellphone ban in classrooms across the
• 15:32
  province, affecting students from Grade 7 to Grade 12.
• 15:36
  This ban means that cellphones can only be used during class if an educator gives permission or
• 15:41
  if a student has special education or medical needs.
• 15:45
  Now, two months in, we're beginning to see the effects of this policy on students' daily
• 15:49
  lives.
• 15:51
  Tiffany Mongu from CBC News spoke to several high school students about their experiences
• 15:57
  since the ban took effect.
• 15:59
  Kenlynn Harvie, a Grade 11 student, shared that attending class without her cellphone hasn't
• 16:05
  been too challenging.
• 16:07
  She noted that while the restrictions on social media like TikTok and Snapchat can be
• 16:12
  frustrating during breaks, the absence of these distractions during class has helped her focus
• 16:18
  better.
• 16:20
  She finds herself taking more handwritten notes, which might have seemed inconvenient
• 16:25
  before, but now feels beneficial.
• 16:28
  The impact on mental health is another area of interest.
• 16:32
  Samantha Vieira, a Grade 12 student at London Central Secondary School, remarked that not
• 16:38
  having her phone constantly at hand has reduced her anxiety about the outside world.
• 16:45
  She feels more present and engaged in her school environment, which has been a positive
• 16:50
  change.
• 16:51
  Vieira also mentioned that the reduction in social media use has helped ease the tension
• 16:57
  around cyber-bullying, creating a calmer atmosphere among her peers.
• 17:02
  Research has long suggested that excessive exposure to social media can negatively impact
• 17:07
  mental health, particularly among children and adolescents.
• 17:11
  By limiting cellphone use in schools, educators hope to prioritize students' mental well-being
• 17:16
  and reduce distractions.
• 17:18
  The feedback from students like Harvie and Vieira suggests that the ban may be achieving
• 17:22
  these goals, at least in part.
• 17:25
  While some students miss the convenience of having their devices during downtime, the
• 17:30
  overall sentiment appears to be positive, with many acknowledging the benefits of reduced
• 17:35
  screen time in an educational setting.
• 17:38
  As we continue to navigate the balance between technology and education, these insights from
• 17:44
  students provide valuable perspectives on how such policies can influence both learning and
• 17:50
  mental health.
• 17:52
  And with that, we've reached the end of today's episode of Morning Medical with Dr.
• 17:57
  Chow.
• 17:58
  Thank you for joining me as we explored these pressing health topics.
• 18:02
  Remember to take care of your health, stay informed, and look out for one another.
• 18:07
  We'll be back tomorrow with more updates from the world of medicine and health.
• 18:11
  Take care and have a wonderful day.
