  Welcome to another episode of Morning Medical with Dr.
• 0:03
  Chow, where we bring you the latest updates in medical and health news from around the world
• 0:08
  using artificial intelligence.
• 0:10
  I'm your host, Dr.
• 0:12
  Chi-Ming Chow, a family physician, general internist, and cardiologist.
• 0:18
  Today, we're diving into an intriguing study that challenges some conventional wisdom about
• 0:24
  sleep positions for patients with glaucoma.
• 0:30
  Let's talk about a recent study that suggests sleeping with two pillows might not be as
• 0:36
  beneficial for glaucoma patients as previously thought.
• 0:40
  Traditionally, many eye specialists have recommended raising the head during sleep to
• 0:44
  help manage intraocular pressure, or IOP, which is critical in glaucoma management.
• 0:50
  However, this new research hints that doing so might actually increase IOP rather than
• 0:56
  decrease it.
• 0:57
  The study involved 144 glaucoma patients and found that those who slept with their heads
• 1:03
  elevated on two stacked pillows experienced slightly higher IOP compared to when they slept
• 1:11
  flat on their backs.
• 1:12
  Specifically, the intraocular pressure was 17.42 millimeters of mercury with the pillows,
• 1:21
  compared to 16.62 millimeters of mercury without.
• 1:26
  This might seem like a small difference, but in patients with advanced glaucoma or those with
• 1:31
  low IOP during the day, even a modest increase can be significant.
• 1:36
  So, why does this happen?
• 1:39
  The researchers, led by Dr.
• 1:41
  Kaijun Wang from Zhejiang University, suggest that the elevated head position could lead to
• 1:46
  neck flexion.
• 1:48
  This might compress the jugular veins, impeding the outflow of aqueous humor, which in turn
• 1:53
  elevates intraocular pressure.
• 1:56
  They even backed up their findings with an ultrasound study on healthy volunteers, which
• 2:01
  showed increased blood flow velocity and constriction in the jugular veins when using
• 2:06
  the high-pillow position.
• 2:08
  It's worth noting that these results don't apply to those who sleep on their sides, as the
• 2:13
  study specifically looked at patients in a supine position.
• 2:18
  Dr.
• 2:18
  Thomas V.
• 2:20
  Johnson from Johns Hopkins University, who was not involved in the study, pointed out that
• 2:25
  while the findings are intriguing, they aren't definitive.
• 2:29
  He emphasized the importance of long-term interventional studies to truly understand the
• 2:34
  impact of sleep positions on glaucoma progression.
• 2:38
  For now, the advice seems to be that glaucoma patients should sleep in whatever position
• 2:42
  makes them comfortable, as there's not enough strong evidence to recommend otherwise.
• 2:47
  This study certainly opens up new avenues for research and discussion about how we manage
• 2:52
  sleep recommendations for glaucoma patients.
• 2:56
  Our next story takes us to the United Kingdom, where a woman named Hollie Thursby experienced
• 3:01
  a life-changing event following an unusual reaction to alcohol.
• 3:05
  After giving birth to her second child, she started experiencing unbearably itchy skin, a
• 3:11
  symptom often attributed to hormonal changes post-pregnancy.
• 3:15
  However, it was her painful reaction to drinking wine that led to a significant medical
• 3:20
  discovery.
• 3:22
  Hollie, a mother of two, noticed that after consuming just a couple of glasses of wine, she
• 3:27
  felt a lot of pain down the side of her neck.
• 3:30
  Initially, she thought it might just be a postpartum symptom or perhaps linked to the
• 3:35
  exhaustion of caring for her children.
• 3:38
  But things took a concerning turn when she also felt like someone was sitting on her chest when
• 3:43
  she went to bed.
• 3:45
  In July 2025, she discovered a lump on the side of her neck.
• 3:49
  Describing it as "really quite big," Hollie noted that it was hard and immobile, a worrying
• 3:55
  sign that prompted her to seek medical attention.
• 3:59
  Unfortunately, the lump turned out to be a manifestation of Stage 2 Hodgkin's lymphoma, a
• 4:04
  type of blood cancer affecting the lymph nodes.
• 4:08
  Hodgkin's lymphoma is known for several symptoms, including swelling of the lymph
• 4:12
  nodes, weight loss, persistent cough, and indeed, pain in the lymph nodes after consuming
• 4:18
  alcohol.
• 4:19
  This alcohol-related pain, although a recognized symptom since the 1950s, is quite
• 4:25
  rare, making Hollie's case particularly noteworthy.
• 4:29
  Hollie began chemotherapy in November and faced the difficult reality of not being able to care
• 4:34
  for her children as she began treatment.
• 4:37
  Her case underscores the importance of paying attention to unusual symptoms and seeking
• 4:42
  medical advice when something feels off, especially when it follows a consistent pattern
• 4:46
  like alcohol-induced pain.
• 4:49
  This story is a poignant reminder that sometimes, seemingly minor symptoms can be the
• 4:54
  body's way of signaling a more serious underlying condition.
• 4:58
  It highlights the importance of listening to one's body and consulting healthcare
• 5:03
  professionals when needed, even if the symptoms appear to be linked to something as common as
• 5:08
  postpartum changes or the occasional glass of wine.
• 5:13
  The topic of fermented foods has been making waves recently, especially after Robert F.
• 5:17
  Kennedy Jr., the Health and Human Services Secretary, made a bold claim about losing
• 5:22
  twenty pounds in just twenty days by eating fermented foods like yogurt, kimchi, and
• 5:28
  sauerkraut.
• 5:29
  While fermented foods have long been celebrated for their potential gut health benefits,
• 5:34
  experts are urging caution about attributing such rapid weight loss to fermentation alone.
• 5:40
  Nutrition specialists suggest that other factors such as calorie restriction, water
• 5:44
  loss, or broader dietary changes might be more plausible explanations for Kennedy's weight
• 5:50
  loss.
• 5:51
  Marian Glick-Bauer, a manager of nutrition and dietetics at Long Island Jewish Medical Center,
• 5:56
  highlights that fermented foods have traditionally been part of a balanced diet rich
• 6:00
  in whole foods, fruits, vegetables, and proteins.
• 6:05
  She cautions against expecting miracle effects from simply adding a cup of yogurt to an
• 6:10
  otherwise unhealthy diet.
• 6:13
  Kennedy's recent comments about his restrictive eating pattern, where he claims to eat only
• 6:17
  meat or fermented foods, have raised eyebrows.
• 6:21
  Glick-Bauer questions the sustainability of such a diet and warns that a sudden shift to
• 6:27
  consuming large amounts of fermented foods can lead to gastrointestinal discomfort, including
• 6:31
  bloating and gas.
• 6:33
  She emphasizes the importance of introducing these foods gradually to allow the digestive
• 6:38
  system to adjust.
• 6:40
  Fermented foods, which are produced through the breakdown of sugars by microorganisms like
• 6:44
  bacteria or yeast, can indeed alter nutrient profiles and introduce live microbes.
• 6:50
  Common examples include yogurt with live cultures, kefir, kimchi, sauerkraut, miso,
• 6:56
  tempeh, and kombucha.
• 6:58
  These foods have been part of human diets for thousands of years, offering potential benefits
• 7:03
  such as supporting metabolic health, reducing inflammation, and increasing gut microbiome
• 7:08
  diversity.
• 7:10
  However, Robert Hutkins, a researcher from the University of Nebraska, points out that much of
• 7:16
  the evidence linking fermented foods to health benefits is observational.
• 7:21
  While some studies suggest these foods can increase gut microbial diversity, the evidence
• 7:25
  for dramatic short-term weight loss remains limited.
• 7:28
  Hutkins also notes that not all fermented foods contain live microbes due to processing steps,
• 7:34
  so their benefits can vary.
• 7:37
  Ultimately, fermented foods can support beneficial gut bacteria, but they should be
• 7:42
  part of a comprehensive dietary pattern that includes other nourishing foods like fruits,
• 7:48
  vegetables, whole grains, and legumes.
• 7:52
  As Glick-Bauer explains, increasing healthy bacteria in the gut is a two-pronged approach:
• 7:58
  consuming fermented foods and eating a diet that provides the necessary fiber for those
• 8:03
  microbes to thrive.
• 8:05
  This holistic approach is essential for promoting overall gut health and well-being.
• 8:12
  Now, let's discuss an interesting perspective from Skylar Griggs, a registered dietitian, on
• 8:18
  navigating the new 'upside down food pyramid' with her patients.
• 8:23
  Skylar recalls when MyPlate was introduced in June 2011, replacing the MyPyramid as the
• 8:29
  United States nutrition guide.
• 8:31
  She was preparing to become a practicing registered dietitian at the time and
• 8:36
  appreciated MyPlate's simplicity, which made it easier to provide actionable advice like "make
• 8:41
  half your plate fruits and vegetables."
• 8:45
  However, the introduction of the new 'upside down food pyramid' has been quite the opposite
• 8:51
  experience.
• 8:52
  Instead of simplifying nutrition messaging, this visual has made it challenging for both
• 8:57
  Skylar and her patients to derive practical recommendations.
• 9:02
  Despite this, there are aspects of the new pyramid that Skylar appreciates.
• 9:08
  For instance, the emphasis on whole, minimally processed foods aligns with her counseling, and
• 9:15
  the prioritization of vegetables at the top of the pyramid reinforces their central role in a
• 9:20
  healthy diet.
• 9:22
  Skylar also values the inclusion of canned foods in the pyramid, as they can be
• 9:28
  nutritionally comparable to fresh foods and are often more accessible for patients with limited
• 9:34
  time or budget.
• 9:36
  The ranking of fruits has sparked meaningful discussions about dietary quality and fiber
• 9:42
  intake, particularly the benefits of high-fiber fruits like berries over others, such as
• 9:47
  bananas.
• 9:49
  The placement of protein has also been beneficial for discussions, especially with the
• 9:54
  increased attention on protein due to GLP-1 medications and the need to preserve lean body
• 10:00
  mass.
• 10:01
  Many of Skylar's patients fall short of their protein needs, and the pyramid's grouping of
• 10:06
  protein sources helps normalize their intake.
• 10:09
  For example, eggs are highlighted as a high-quality protein source, often
• 10:14
  misunderstood due to outdated dietary guidelines.
• 10:18
  However, the new pyramid is visually overwhelming, and Skylar finds it difficult to
• 10:22
  translate its message into practical advice.
• 10:26
  A significant issue is the confusion surrounding protein sources high in saturated
• 10:31
  fat, like steak, which sit at the top of the pyramid.
• 10:35
  This placement can mislead patients into thinking they should consume more steak, which
• 10:40
  is not typically beneficial for cardiovascular health.
• 10:44
  The depiction of fats also introduces confusion, as the visual hierarchy seems to
• 10:49
  undermine clear messaging about saturated fat.
• 10:52
  For instance, the placement of nuts below avocados, or butter in the middle of the
• 10:57
  pyramid, can lead to misunderstandings about consumption limits.
• 11:01
  Whole grains being at the bottom of the pyramid further complicates matters, as it might
• 11:06
  suggest to patients that these nutritious foods should be avoided.
• 11:10
  The pyramid's lack of emphasis on plant-based protein sources presents challenges for
• 11:16
  patients following vegetarian or flexitarian diets.
• 11:20
  Protein adequacy is often a concern for these patients, and the visual does little to support
• 11:26
  adequate intake of plant-based proteins.
• 11:29
  Skylar finds that prioritizing written dietary guidelines over the visual pyramid is more
• 11:36
  effective for her practice.
• 11:37
  She continues to use Harvard's Healthy Eating Plate as a visual guide, as it offers
• 11:43
  simplified, flexible recommendations.
• 11:46
  This approach underscores the need for individualized nutrition counseling rather than
• 11:51
  a one-size-fits-all solution.
• 11:55
  In closing, while the new 'upside down food pyramid' introduces some helpful concepts, it
• 12:01
  ultimately highlights the importance of tailored nutrition advice.
• 12:04
  As healthcare professionals, we must focus on providing individualized guidance to ensure our
• 12:10
  patients achieve their health goals effectively.
