  Welcome to Morning Medical with Doctor Chow.
• 0:02
  I'm Doctor Chi-Ming Chow, and every day, we dive into the latest medical and health news
• 0:07
  from around the globe.
• 0:08
  As a family physician, general internist, and cardiologist, I'm always excited to share
• 0:14
  insights and updates that could make a difference in your health journey.
• 0:18
  Today, we'll be discussing the new stroke prevention guidelines released by the American
• 0:22
  Stroke Association.
• 0:24
  Let's get into it.
• 0:28
  Stroke is the fifth-leading cause of death in the United States and a leading cause of
• 0:32
  disability.
• 0:33
  However, there's good news: up to eighty percent of strokes are preventable.
• 0:38
  The American Stroke Association recently published updated guidelines for stroke
• 0:42
  prevention, marking the first update since 2014.
• 0:46
  These guidelines are published in the journal Stroke, and they offer a comprehensive approach
• 0:51
  to reducing stroke risk.
• 0:54
  Cheryl Bushnell, a professor of neurology and stroke division chief at Wake Forest University
• 0:59
  Health Sciences, emphasizes the importance of understanding risk factors for stroke and
• 1:04
  having access to appropriate care.
• 1:07
  These risk factors can include conditions such as high blood pressure, high cholesterol, and
• 1:11
  diabetes, which may require medications.
• 1:13
  But lifestyle changes also play a crucial role in prevention.
• 1:18
  The guidelines highlight several lifestyle changes that can significantly reduce stroke
• 1:23
  risk.
• 1:24
  These include maintaining a healthy weight, being physically active, avoiding prolonged
• 1:29
  sitting, eating a healthy diet like the Mediterranean diet, treating sleep apnea, and
• 1:34
  quitting smoking.
• 1:36
  Doctor Bradley Serwer, a cardiologist, notes that these prevention strategies also improve
• 1:41
  overall health by addressing known risk factors like diabetes, hypertension, and high
• 1:47
  cholesterol.
• 1:49
  One of the exciting developments since the last guidelines is the introduction of new
• 1:53
  medications that not only treat diseases like diabetes and obesity but also reduce the risk
• 1:58
  of stroke and heart disease.
• 2:00
  For instance, glucagon-like peptide-1 receptor agonists have shown to drastically reduce blood
• 2:06
  sugar levels in patients with diabetes, leading to significant weight loss and reduced stroke
• 2:11
  risk.
• 2:12
  Additionally, the guidelines recommend the use of PCSK9 inhibitors, a class of drugs effective
• 2:18
  at lowering low-density lipoprotein cholesterol, which also helps reduce stroke
• 2:23
  risk.
• 2:24
  The emphasis on medication is complemented by a strong focus on physical activity.
• 2:30
  The American Stroke Association continues to recommend 150 minutes of moderate-intensity
• 2:35
  physical activity or 75 minutes of vigorous-intensity activity each week, but now
• 2:42
  also stresses the importance of avoiding sedentary behavior during waking hours.
• 2:47
  The updated guidelines include tailored recommendations for specific groups.
• 2:52
  For pregnant women, there are recommendations for managing high blood pressure and screening
• 2:57
  for pregnancy complications.
• 3:00
  All women are advised to be screened for premature ovarian failure, early-onset
• 3:04
  menopause, and endometriosis.
• 3:07
  Furthermore, the guidelines advocate for screening for adverse social determinants of
• 3:12
  health, recognizing that factors like lack of access to healthcare can increase stroke risk.
• 3:18
  Overall, these guidelines provide relatively simple strategies that can effectively lower
• 3:23
  stroke risk and improve brain health.
• 3:26
  Doctor Bushnell points out that the risks for dementia are similar to those for stroke, so
• 3:31
  these preventive measures can have broader benefits.
• 3:35
  Doctor Serwer adds that the updated guidelines reflect significant research and clinical
• 3:40
  lessons learned over the past decade, emphasizing the importance of early
• 3:44
  intervention in preventing strokes, much like coronary artery disease and heart attacks.
• 3:51
  Recent research has highlighted the potential health risks associated with a high sugar
• 3:55
  intake, emphasizing how cutting back on sugar may significantly lower your risk of developing
• 4:00
  conditions like type two diabetes, stroke, and depression.
• 4:05
  This study, published in the Journal of Translational Medicine, sheds light on the
• 4:10
  detrimental effects of excessive sugar consumption on both physical and mental health.
• 4:16
  The study explored how individuals with a sweet tooth are at a greater risk of depression
• 4:22
  compared to those who prefer healthier foods.
• 4:25
  It also linked a preference for sugary foods with higher levels of inflammation, blood
• 4:30
  sugar, and lipids, which are indicators of metabolic disease risk.
• 4:35
  These findings point to the importance of reconsidering dietary choices, especially for
• 4:40
  those who consume sugar-rich foods regularly.
• 4:44
  Data analyzed from the UK Biobank, which includes health and genetic information from
• 4:49
  half a million volunteers, revealed distinct patterns based on food preferences.
• 4:54
  Participants were categorized into three groups: Health-conscious, Omnivore, and
• 4:59
  Sweet-tooth.
• 5:01
  Those in the Sweet-tooth group showed higher C-reactive protein levels, a marker for
• 5:06
  inflammation, and had elevated blood sugar and lipid levels, increasing their risk for
• 5:11
  conditions like diabetes and cardiovascular disease.
• 5:16
  Interestingly, the study found that those with healthier eating patterns had a reduced risk of
• 5:20
  heart disease and stroke.
• 5:22
  The Health-conscious group, who preferred vegetables and fresh fruit, demonstrated a
• 5:26
  lower risk of heart failure, chronic kidney disease, and stroke, in contrast to the
• 5:31
  Sweet-tooth group.
• 5:33
  Meanwhile, the Omnivore group exhibited moderate health risks.
• 5:37
  Doctor Michael O.
• 5:39
  McKinney, a physician and nutritionist, explains that sugar impacts the body's
• 5:44
  functioning by causing blood sugar levels to spike, which in turn increases insulin
• 5:50
  production.
• 5:51
  Over time, this can lead to insulin resistance, a root cause of metabolic illnesses such as
• 5:58
  type two diabetes.
• 6:00
  Excess sugar intake also contributes to high inflammation levels, which are linked with
• 6:05
  heart disease, stroke, and mental health conditions like depression and anxiety.
• 6:11
  Reducing sugar consumption doesn’t have to be overwhelming.
• 6:16
  Doctor Ramit Singh Sambyal, a general physician, suggests making small, sustainable
• 6:22
  changes.
• 6:23
  Start by identifying hidden sugars in everyday foods, such as sauces and flavored yogurts, and
• 6:29
  opt for whole fruits instead of sugary snacks.
• 6:34
  Gradual changes, like using less sugar in coffee or switching to water instead of sugary
• 6:39
  drinks, can make a big difference over time.
• 6:42
  While cutting sugar can lead to temporary detox symptoms, many find that they feel better
• 6:48
  within a few weeks.
• 6:49
  Improvements in energy levels and mood are common, particularly for those struggling with
• 6:54
  depression.
• 6:55
  By reducing sugar intake, you're not only lowering your risk of depression but also
• 7:00
  protecting yourself from heart disease and diabetes in the long run.
• 7:05
  In summary, this study underscores the importance of reducing sugar consumption for
• 7:10
  both physical and mental well-being.
• 7:13
  Small changes to your diet can add up over time, leading to a healthier and happier you.
• 7:19
  It's a reminder that even modest dietary adjustments can have profound impacts on your
• 7:24
  overall health.
• 7:26
  A recent study has shed light on a potential early warning sign for Parkinson's disease:
• 7:31
  hearing loss.
• 7:33
  According to research led by Doctor Lee Neilson from Oregon Health and Science University,
• 7:38
  hearing loss may increase the risk of developing Parkinson's disease later in life.
• 7:44
  This study, published in JAMA Neurology, analyzed medical records from over 3.6 million
• 7:50
  United States military veterans.
• 7:54
  Over an average follow-up of 7.6 years, researchers found that hearing loss was
• 7:59
  associated with the onset of Parkinson's disease in a dose-dependent manner.
• 8:04
  This means that the more severe the hearing loss, the higher the risk of developing
• 8:09
  Parkinson's.
• 8:11
  The study reported that individuals with mild hearing loss experienced 6.1 extra cases of
• 8:16
  Parkinson's disease per ten years compared to those with normal hearing.
• 8:20
  For those with moderate hearing loss, the number increased to 15.8 cases, and for
• 8:25
  moderate-to-severe hearing loss, it rose to 16.2 cases.
• 8:30
  Those with severe-to-profound hearing loss saw 12.1 extra cases.
• 8:36
  These findings suggest a clear link between the severity of hearing loss and the risk of
• 8:41
  Parkinson's disease.
• 8:43
  Interestingly, the study also highlighted the potential benefits of early intervention with
• 8:48
  hearing aids.
• 8:49
  When hearing aids were provided within two years of an initial audiogram, the incidence of
• 8:54
  Parkinson's disease decreased by 21.6 cases per ten years.
• 9:00
  This suggests that addressing hearing loss early could potentially mitigate the risk of
• 9:04
  developing Parkinson's disease.
• 9:07
  Doctor Neilson emphasized the importance of identifying and addressing hearing loss as a
• 9:12
  modifiable risk factor for Parkinson's disease.
• 9:16
  He noted that while we know about many risk factors for Parkinson's, including sensory
• 9:20
  impairments like color vision and anosmia, hearing loss is unique because it can be
• 9:26
  improved with interventions such as hearing aids.
• 9:31
  This provides a tangible opportunity for early intervention that could have significant
• 9:36
  long-term benefits.
• 9:39
  The study utilized the extensive medical records from the Department of Veterans
• 9:43
  Affairs, examining nearly all veterans who underwent hearing tests between 1999 and 2022.
• 9:51
  The study population was predominantly male, with a mean age of 67.
• 9:56
  At the time of their audiometry exams, 20.8% had normal hearing, while the rest had varying
• 10:03
  degrees of hearing loss, ranging from mild to severe.
• 10:08
  Researchers noted that hearing loss was consistently linked with an increased risk of
• 10:12
  Parkinson's disease, even in the absence of other known risk factors like traumatic brain
• 10:18
  injury or tinnitus.
• 10:21
  This is particularly notable because tinnitus, common among veterans, can influence sleep and
• 10:26
  mood symptoms associated with Parkinson's disease.
• 10:30
  Doctor Neilson and his colleagues found a significant reduction in Parkinson's incidence
• 10:34
  as early as one year after individuals received hearing aids.
• 10:38
  They estimated that for every 462 people treated with a hearing aid after an abnormal
• 10:44
  audiogram, one case of Parkinson's could potentially be prevented over ten years.
• 10:50
  Despite the promising findings, the study had some limitations.
• 10:54
  It primarily included white male veterans, which may limit the generalizability of the
• 11:00
  results.
• 11:01
  Additionally, unmeasured factors such as exposure to ototoxic drugs were not accounted
• 11:07
  for, and the exact mechanisms linking hearing loss to Parkinson's disease remain unclear.
• 11:14
  Nonetheless, this research underscores the importance of screening for hearing loss and
• 11:19
  intervening early.
• 11:21
  As Doctor Neilson pointed out, while there's still much to learn about how hearing loss
• 11:25
  contributes to Parkinson's, the evidence supports the need for population-level
• 11:29
  screening and intervention.
• 11:31
  This could represent a significant step forward in reducing the risk of Parkinson's disease
• 11:36
  through early detection and management of hearing loss.
• 11:41
  A recent study suggests that drinking coffee during pregnancy may not be as risky as
• 11:46
  previously thought, finding no strong link between caffeine consumption and
• 11:51
  neurodevelopmental issues in children.
• 11:53
  This study, published in Psychological Medicine, suggests that moderate coffee
• 11:58
  consumption during pregnancy is unlikely to have a significant effect on a child's brain
• 12:03
  development.
• 12:03
  Co-author Gunn-Helen Moen from the University of Queensland’s Institute for Molecular
• 12:09
  Bioscience stated, "Our analysis found no link between coffee consumption during pregnancy and
• 12:15
  children’s neurodevelopmental difficulties." This supports current clinical guidelines that
• 12:20
  say low to moderate coffee consumption during pregnancy is safe for both the mother and the
• 12:26
  developing baby.
• 12:29
  The Public Health Agency of Canada echoes these findings, stating that drinking caffeine while
• 12:34
  pregnant is safe in small amounts.
• 12:37
  Their guidelines recommend keeping caffeine intake below three hundred milligrams a day,
• 12:41
  which is about two cups of coffee.
• 12:44
  This recommendation also includes other sources of caffeine like tea, cola beverages, energy
• 12:49
  drinks, chocolate, and certain herbs.
• 12:53
  Doctor Lynn Murphy-Kaulbeck, a maternal-fetal medicine specialist and president of the
• 12:58
  Society of Obstetricians and Gynecologists of Canada, noted, "There are no studies to show
• 13:04
  that it has a detrimental effect on the fetus.
• 13:08
  I generally say one to two cups per day is fine." She also mentioned that some studies
• 13:14
  suggest high caffeine intake very early in pregnancy may be a risk factor for miscarriage,
• 13:21
  but that is with high amounts, equivalent to six or more cups a day.
• 13:26
  Prior studies linked increased coffee consumption during pregnancy with children's
• 13:31
  neurodevelopmental difficulties like attention-deficit hyperactivity disorder.
• 13:36
  This concern arises because caffeine and its byproducts can easily pass through the placenta
• 13:42
  to the fetus.
• 13:43
  The fetus, lacking the enzymes to break down caffeine, could potentially accumulate it,
• 13:49
  affecting brain development.
• 13:51
  However, the recent study, which involved tens of thousands of families from the Norwegian
• 13:56
  Mother, Father, and Child Cohort Study, found little evidence for a causal effect between
• 14:01
  maternal coffee consumption and most offspring neurodevelopmental difficulties.
• 14:07
  The study accounted for potential confounding factors such as maternal smoking, alcohol
• 14:11
  consumption, and parental education and income.
• 14:16
  The researchers concluded that while they could rule out strong effects on neurodevelopmental
• 14:20
  difficulties, small effects might still exist.
• 14:24
  They emphasized the need for more research to better understand how maternal coffee
• 14:30
  consumption impacts child development.
• 14:33
  Nevertheless, they maintain that low to moderate coffee consumption during pregnancy is
• 14:39
  safe.
• 14:41
  In summary, pregnant individuals can take comfort that moderate coffee consumption is
• 14:46
  unlikely to harm neurodevelopment.
• 14:48
  This aligns with existing advice to keep caffeine intake moderate during pregnancy.
• 14:54
  As Doctor Murphy-Kaulbeck said, "I think women need to hear that it’s OK to drink a coffee
• 14:59
  while pregnant.
• 15:00
  They don’t need to worry; in fact, they should enjoy it."
• 15:05
  That wraps up today's episode of Morning Medical with Doctor Chow.

  We've covered some fascinating topics, from new stroke prevention guidelines to the potential
• 15:13
  link between hearing loss and Parkinson's disease, and the reassuring news about coffee
• 15:19
  consumption during pregnancy.
