• 0:04
  I'm Dr.
• 0:05
  Chi-Ming Chow, and today we've got some intriguing topics lined up for you.
• 0:10
  Let's dive right into our first story, which explores a recent discovery about microplastics
• 0:15
  in the human body.
• 0:20
  Scientists have found microplastics in human semen and follicular fluid.
• 0:24
  This research, published in the journal Human Reproduction, involved a small group of 25
• 0:29
  women and 18 men.
• 0:32
  They discovered microplastics in 69 percent of the follicular fluid samples and 55 percent of
• 0:38
  the seminal fluid samples.
• 0:40
  Now, follicular fluid is the liquid that surrounds an egg in an ovarian follicle.
• 0:45
  The findings were presented at the 41st Annual Meeting of the European Society of Human
• 0:51
  Reproduction and Embryology in Paris.
• 0:56
  Dr.

  Emilio Gómez-Sánchez, the lead author of the research, noted that while the presence of
• 1:02
  microplastics in the human reproductive system wasn't entirely unexpected, the extent of their
• 1:08
  presence was surprising.
• 1:11
  It seems to be quite common, rather than an isolated finding.
• 1:16
  Microplastics, which are tiny polymer fragments, primarily enter the body through
• 1:21
  ingestion, inhalation, and skin contact.
• 1:25
  From there, they can enter the bloodstream and be distributed throughout the body, including
• 1:30
  the reproductive organs.
• 1:33
  The research team found a variety of microplastics in the reproductive fluids,
• 1:37
  including polymers like polyamide, polyurethane, and polyethylene, which were
• 1:42
  prevalent in over 50 percent of the follicular fluid samples.
• 1:47
  Semen samples also contained microplastics, with 56 percent containing
• 1:52
  polytetrafluoroethylene, commonly known as PTFE.
• 1:57
  It’s important to note that the concentrations of microplastics were relatively low compared
• 2:01
  to non-plastic particles in these samples.
• 2:05
  While these findings are preliminary and the effects of microplastics on human health are
• 2:09
  still not fully understood, they do raise important questions.
• 2:15
  For now, people trying to conceive may not need to be overly concerned, as the research is
• 2:20
  still in its early stages.
• 2:22
  However, it does highlight the need for more studies to understand the potential impact of
• 2:28
  microplastics on reproductive health and overall human health.
• 2:33
  Experts suggest that while individual actions to reduce plastic use are beneficial, the
• 2:38
  conversation should shift towards policymakers making significant changes to waste management
• 2:44
  and recycling policies.
• 2:46
  The global production of plastics has increased dramatically over the years and is expected to
• 2:50
  continue rising.
• 2:53
  Today, we're turning our attention to a significant study on pediatric urinary
• 2:58
  incontinence and its potential impact on academic performance.
• 3:03
  This research, recently published in the Journal of Urology, sheds light on how urinary
• 3:08
  incontinence in children might intersect with psychiatric conditions and school performance.
• 3:15
  The study, conducted by researchers in Denmark, involved a large matched cohort of children.
• 3:21
  It aimed to explore whether urinary incontinence in children is linked to lower
• 3:25
  performance on standardized school tests.
• 3:28
  The study included over forty-two thousand children diagnosed with urinary incontinence
• 3:33
  and compared them to a reference group of over four hundred thousand children without the
• 3:38
  condition.
• 3:39
  Interestingly, the study found that urinary incontinence itself minimally affected academic
• 3:46
  performance.
• 3:47
  However, children with co-occurring psychiatric disorders, such as attention
• 3:51
  deficit-hyperactivity disorder, had poorer academic outcomes.
• 3:55
  This suggests that psychiatric evaluations might be beneficial for children with urinary
• 4:00
  incontinence before beginning treatment, especially since these conditions are
• 4:05
  overrepresented in this population.
• 4:09
  The study further revealed that children with nocturnal enuresis, a type of urinary
• 4:14
  incontinence, had statistically lower test scores compared to those without the condition.
• 4:21
  This was particularly evident in language scores among eighth graders.
• 4:26
  On the other hand, daytime urinary incontinence did not show significant associations with test
• 4:31
  scores, except for a slight impact on language scores.
• 4:36
  Moreover, the research highlighted that children with both urinary incontinence and
• 4:40
  psychiatric disorders performed worse across various grades, with the most significant
• 4:45
  differences observed in sixth and eighth-grade math scores.
• 4:49
  This underscores the necessity for a multidisciplinary approach in caring for
• 4:54
  pediatric patients with urinary incontinence, involving specialists who understand childhood
• 5:00
  neurologic development.
• 5:03
  The data for this study was sourced from Denmark's extensive national electronic health
• 5:07
  record system, which allowed researchers to conduct comprehensive longitudinal studies.
• 5:13
  However, as noted by Chester Koh, a pediatric urologist involved in the research
• 5:17
  collaboration, similar studies in the United States would be necessary to determine if the
• 5:23
  findings are consistent across different populations.
• 5:27
  This study emphasizes the importance of considering psychiatric evaluations for
• 5:32
  children with urinary incontinence, particularly given the potential impact on
• 5:37
  their academic performance and overall development.
• 5:40
  As always, further research is essential to continue understanding and improving care for
• 5:45
  these young patients.
• 5:49
  Let's talk about a topic that has sparked many debates among pet owners: whether or not to let
• 5:54
  your dog or cat sleep in your bed.
• 5:57
  CNN's Randi Kaye and Sarah Boxer explored this issue and found that sharing your bed with a
• 6:04
  furry friend can have both positive and negative effects on your well-being.
• 6:08
  For some people, having a dog or cat in bed can provide a sense of comfort and security.
• 6:15
  The rhythmic breathing of a pet can be soothing and help some individuals fall asleep more
• 6:20
  easily.
• 6:22
  This companionship can reduce feelings of loneliness and anxiety, potentially leading to
• 6:27
  better overall mental health.
• 6:30
  However, there are downsides to consider.
• 6:33
  Pets can disrupt your sleep by moving around, snoring, or taking up too much space.
• 6:39
  This can lead to a less restful night's sleep, which can affect your mood, productivity, and
• 6:45
  health the following day.
• 6:47
  For those who are light sleepers, having a pet in bed might not be the best choice.
• 6:52
  Additionally, if you or your partner suffers from allergies, having a pet in the bed can
• 6:58
  exacerbate symptoms.
• 7:00
  Pet dander and fur can trigger allergic reactions, making it difficult to get a good
• 7:06
  night's sleep.
• 7:07
  It's important to weigh these factors when deciding whether or not to allow your pet to
• 7:12
  share your sleeping space.
• 7:15
  Ultimately, the decision to let your pet sleep in your bed is a personal one.
• 7:20
  It depends on your individual circumstances and preferences.
• 7:23
  If you find comfort and restfulness with your pet by your side, then it might be beneficial.
• 7:29
  But if your sleep is regularly disturbed, it might be worth reconsidering your sleeping
• 7:34
  arrangements.
• 7:37
  Let's delve into a new study that might make you reconsider that afternoon nap.
• 7:41
  Presented at the thirty-ninth annual meeting of the Associated Professional Sleep Societies in
• 7:46
  Seattle, Washington, this research explored the relationship between daytime napping and
• 7:51
  mortality rates in older adults.
• 7:53
  According to the study, longer and irregular naps, especially in the early afternoon, could
• 7:58
  be linked to a higher risk of death over an eight-year period.
• 8:02
  The study was conducted by a team led by Chenlu Gao, a postdoctoral research fellow at
• 8:08
  Massachusetts General Hospital in Boston.
• 8:11
  It involved eighty-six thousand five hundred sixty-five participants with an average age of
• 8:16
  sixty-three, all working regular daytime schedules.
• 8:20
  These individuals were monitored using actigraphy, a method that detects movement
• 8:25
  during sleep, though it doesn’t track brain activity.
• 8:29
  Researchers found that frequent, longer, and irregular daytime naps were associated with a
• 8:35
  higher risk of mortality.
• 8:37
  They defined daytime napping as sleeping between nine a.m.
• 8:41
  and seven p.m., and discovered that naps taken between eleven a.m.
• 8:46
  and three p.m.
• 8:47
  were particularly linked to increased mortality rates.
• 8:51
  The results were adjusted for factors like demographics, weight, smoking, alcohol
• 8:56
  consumption, and nighttime sleep duration.
• 9:00
  Dr.
• 9:00
  Chelsie Rohrscheib, a neuroscientist and sleep specialist not involved in the study, explained
• 9:06
  that naps aren't necessarily problematic unless they're used to compensate for poor nighttime
• 9:11
  sleep.
• 9:12
  She emphasized the importance of getting seven to nine hours of quality sleep at night to
• 9:17
  reduce the risk of serious health conditions like heart disease and diabetes.
• 9:22
  It's important to note that this study didn't establish a direct causal relationship between
• 9:27
  napping and increased mortality risk.
• 9:30
  Instead, it highlighted associations that suggest excessive napping might be indicative
• 9:36
  of underlying health issues, such as chronic disease or disruptions to circadian rhythms,
• 9:42
  which could themselves elevate mortality risk.
• 9:46
  The researchers acknowledged some limitations in their study.
• 9:50
  For instance, the reliance on movement detection rather than brain activity meant that
• 9:55
  quiet wakefulness could have been misclassified as sleep.
• 9:59
  Additionally, their definition of daytime napping might have included participants'
• 10:03
  actual sleep, affecting the study's accuracy.
• 10:07
  The American Academy of Sleep Medicine advises healthy adults to limit naps to no longer than
• 10:12
  twenty to thirty minutes in the early afternoon.
• 10:15
  Brief "power naps" can enhance alertness and performance, but longer naps might lead to
• 10:20
  grogginess, delaying their benefits.
• 10:24
  In conclusion, while napping can be beneficial, moderation is key.
• 10:29
  Monitoring napping patterns could potentially help identify broader health concerns, making
• 10:34
  it a topic worth discussing with a healthcare provider.
• 10:37
  That wraps up today's episode.
