Respiratory Infections in China, Calcium and Cancer, and Alcohol's Health Impact · Morning Medical with Dr. Chow

• 0:00
  Good morning and welcome to another episode of Morning Medical with Dr.
• 0:04
  Chow.
• 0:04
  I'm your host, Dr.
• 0:06
  Chi-Ming Chow.
• 0:07
  Today, we're diving into some of the latest health news making waves around the globe.
• 0:12
  We'll start with a topic that's been capturing attention: the rising cases of human
• 0:16
  metapneumovirus in China.
• 0:19
  Let's unpack what's happening.
• 0:23
  Human metapneumovirus, or hMPV, is a common respiratory infection that typically causes
• 0:30
  cold-like symptoms.
• 0:32
  Recently, there's been a surge in cases reported in China, sparking headlines and some
• 0:37
  concern.
• 0:39
  However, the World Health Organization has stepped in to provide some reassurance.
• 0:44
  They describe these rising numbers as 'not unusual' for this time of year, especially
• 0:49
  given the seasonal trends.
• 0:52
  The World Health Organization has been in contact with Chinese health officials who
• 0:56
  confirm that, despite the increase in cases, there are no signs of an overwhelmed health
• 1:01
  system or any need for emergency responses.
• 1:04
  This is a stark contrast to the situation we faced with the COVID-19 pandemic, and it's
• 1:09
  important to note that the current situation is within expected norms for this season.
• 1:15
  Data from China up until December 29th show increased detections of not only hMPV but also
• 1:21
  seasonal influenza, rhinovirus, and respiratory syncytial virus.
• 1:27
  Among these, influenza is currently the most commonly reported cause of illness.
• 1:32
  These increases are in line with what we typically see during the winter months,
• 1:36
  particularly in the Northern Hemisphere.
• 1:39
  It's worth mentioning that hMPV, first identified in 2001, isn't a new virus.
• 1:44
  In fact, most children will have been infected with it at least once by their fifth birthday.
• 1:49
  In rare cases, it can lead to hospitalization, particularly among the very young, elderly, or
• 1:55
  those with weakened immune systems.
• 1:57
  However, for the majority, it results in mild symptoms and resolves on its own.
• 2:03
  Experts suggest that the rise in reported cases might also be attributed to improvements in
• 2:08
  diagnosing the virus, rather than an actual increase in infections.
• 2:13
  As our diagnostic capabilities improve, we're better able to identify and track these cases,
• 2:19
  providing a clearer picture of their prevalence.
• 2:22
  In summary, while the headlines might seem alarming, the experts, including those from the
• 2:26
  World Health Organization, assure us that there's no major cause for concern.
• 2:31
  Basic health measures remain effective defenses against these respiratory infections, and
• 2:36
  staying informed is key to managing our health during the winter season.
• 2:42
  Our next topic revolves around the fascinating findings from a recent study suggesting that
• 2:47
  calcium-rich foods, such as milk, may play a significant role in reducing the risk of
• 2:53
  colorectal cancer.
• 2:55
  This large-scale study, conducted in the United Kingdom and published in Nature Communications,
• 3:01
  provides compelling evidence on the potential protective benefits of calcium in our diets.
• 3:07
  The research indicates that consuming an additional 300 milligrams of calcium daily,
• 3:12
  which is roughly the amount found in a large glass of dairy milk or a cup of yogurt, is
• 3:17
  linked to a 17 percent reduction in the risk of developing colorectal cancer.
• 3:22
  This makes it one of the most comprehensive studies to date examining the relationship
• 3:26
  between diet and colorectal cancer.
• 3:30
  Colorectal cancer, as many of you might know, is the third most common cancer worldwide.
• 3:36
  In Canada, it was projected to be the fourth most commonly diagnosed cancer in 2024,
• 3:42
  excluding non-melanoma skin cancers.
• 3:46
  It ranks as the second leading cause of cancer-related death among men and the third
• 3:50
  among women.
• 3:52
  Interestingly, there's been a worrying increase in colorectal cancer cases among younger
• 3:57
  people, although the reasons for this trend remain unclear.
• 4:01
  Dr.
• 4:01
  Barry Stein, president and chief executive officer of Colorectal Cancer Canada,
• 4:07
  highlighted that while the link between calcium and reduced colorectal cancer risk is not
• 4:11
  entirely new, this study adds further confirmation to existing research.
• 4:17
  The World Cancer Research Fund and the American Institute for Cancer Research have long
• 4:23
  suggested that calcium may decrease the risk of colorectal cancer.
• 4:28
  However, the researchers from the United Kingdom noted that there's been a lack of
• 4:33
  consensus on the role of various dietary factors, other than alcohol and processed meat,
• 4:39
  in colorectal cancer risk.
• 4:42
  This study aims to fill that gap and provide more clarity.
• 4:47
  The study analyzed data from over 540,000 women, examining their intake of 97 dietary
• 4:54
  products and nutrients over an average of 16 years.
• 4:58
  Among the 17 dietary factors studied, calcium and alcohol were the most strongly linked to
• 5:04
  colorectal cancer risk, with calcium showing a protective effect and alcohol increasing the
• 5:09
  risk.
• 5:10
  Calcium is most commonly associated with maintaining healthy bones and teeth, but it
• 5:15
  also plays crucial roles in blood clotting, muscle contraction, and regulating heart
• 5:19
  rhythms.
• 5:20
  It's found in dairy products, certain dark green vegetables, leafy greens, and even some
• 5:26
  fish and shellfish.
• 5:28
  The researchers suggest that calcium might protect against bowel cancer by binding to bile
• 5:34
  acids and free fatty acids, forming a harmless compound that prevents damage to the gut
• 5:39
  lining.
• 5:41
  However, they caution that the study's participants were predominantly middle-aged and
• 5:45
  older women of European descent, so the findings might not be applicable to other
• 5:50
  populations, especially those with lactose intolerance.
• 5:54
  Despite these limitations, the study provides robust evidence supporting the protective role
• 5:59
  of dietary calcium.
• 6:00
  Dr.
• 6:01
  Stein emphasized that while calcium intake is important, it should be part of an overall
• 6:05
  healthy lifestyle that includes reducing alcohol consumption, limiting red meat, and
• 6:11
  increasing fiber intake through fruits, vegetables, and whole grains.
• 6:16
  Ultimately, the study underscores the importance of a balanced diet and lifestyle in
• 6:22
  reducing colorectal cancer risk.
• 6:25
  Screening remains crucial, particularly for those aged 50 and over, to catch early signs of
• 6:31
  the disease.
• 6:33
  As always, consulting with healthcare professionals about dietary choices and cancer
• 6:37
  prevention strategies is a wise approach.
• 6:42
  With Meta's recent decision to drop its fact-checkers for Instagram and Facebook in the
• 6:47
  United States, many parents are understandably concerned about the potential increase in
• 6:52
  harmful content their children might encounter on social media.
• 6:56
  As the company shifts to allowing users to write “community notes” on problematic posts,
• 7:02
  Meta's Chief Executive Officer, Mark Zuckerberg, has admitted that this change means
• 7:07
  the platform will likely catch less "bad stuff."
• 7:12
  This shift highlights the importance of teaching children critical thinking skills to
• 7:16
  navigate social media effectively.
• 7:18
  It's crucial for parents to engage in discussions with their children about the
• 7:22
  importance of not sharing or acting on claims they see online without verifying them first.
• 7:28
  By empowering kids to be thoughtful consumers of online content, parents can help them
• 7:33
  discern what is reliable and what is not.
• 7:37
  One of the key strategies is encouraging children to confirm information they encounter
• 7:42
  on social media by cross-referencing it with credible mainstream media outlets.
• 7:47
  James P.
• 7:48
  Steyer, founder and Chief Executive Officer of Common Sense Media, suggests that if other
• 7:54
  reputable news sources are not reporting the same information, it warrants further
• 7:59
  investigation.
• 8:01
  This approach fosters a habit of looking beyond the surface and digging deeper into the facts.
• 8:07
  Dr.
• 8:08
  Jingsi Christina Wu, an associate professor of media studies, emphasizes the value of
• 8:14
  consuming more news alongside children.
• 8:17
  By reading or watching the news together, parents and children can have discussions that
• 8:21
  enhance kids' cognitive abilities to interpret media coverage.
• 8:25
  This practice helps kids develop a more nuanced understanding of the news landscape.
• 8:31
  When evaluating social media posts, children should be taught to consider the source of the
• 8:36
  content, its trustworthiness, and the motivations behind it.
• 8:40
  It's important to remind kids that their favorite influencers, while entertaining, are
• 8:45
  not necessarily experts on factual matters and may have their own biases.
• 8:49
  As Dr.
• 8:50
  Wu points out, virality does not equate to truth, and children should be wary of content
• 8:55
  that has gone viral simply due to its sensational nature.
• 9:00
  Another useful tactic is to teach children to look out for telltale signs of unreliable
• 9:05
  posts, such as spelling and grammatical errors or signs of manipulation in images and videos.
• 9:12
  Content that provokes strong emotional reactions should also be viewed with
• 9:17
  skepticism, as misinformation often aims to elicit extreme responses.
• 9:23
  Algorithms on social media platforms are designed to show users content similar to what
• 9:28
  they have previously engaged with.
• 9:30
  Therefore, it's beneficial for parents to guide their children towards consuming content about
• 9:35
  topics that genuinely interest them.
• 9:38
  For instance, if a child is fascinated by animals, watching educational videos from
• 9:43
  reputable organizations can lead to more enriching content being suggested by the
• 9:48
  algorithm.
• 9:49
  Maintaining an open dialogue with children is another critical component.
• 9:55
  Parents should encourage their kids to discuss any uncertainties they have about the accuracy
• 10:02
  of online content.
• 10:04
  Rather than dismissing content as fake outright, parents can research the content
• 10:08
  together with their children.
• 10:10
  This collaborative approach not only keeps the lines of communication open but also
• 10:15
  demonstrates that learning and media literacy are ongoing processes.
• 10:20
  Ultimately, the onus is on parents to prepare their children to navigate the digital world
• 10:25
  safely and responsibly.
• 10:27
  By equipping them with the tools to critically evaluate the content they encounter, parents
• 10:32
  can help mitigate the risks posed by Meta's decision to reduce fact-checking measures.
• 10:39
  In our final segment today, we're delving into the candid insights from Dr.
• 10:44
  Brett Osborn, a Florida neurosurgeon, on the effects of alcohol on the human body.
• 10:50
  Dr.
• 10:50
  Osborn, who also specializes in longevity medicine, recently spoke with Fox News Digital
• 10:57
  following an advisory from the United States Surgeon General about alcohol's link to various
• 11:02
  cancers.
• 11:04
  Dr.
• 11:04
  Osborn applauded the Surgeon General's guidance, emphasizing that alcohol is indeed a
• 11:09
  toxin.
• 11:10
  He remarked, "We've known this for eons — this is nothing new." The advisory highlighted that
• 11:16
  alcohol is linked to at least seven types of cancer, including those of the throat, liver,
• 11:22
  esophagus, mouth, larynx, colon, and rectum.
• 11:27
  Dr.
• 11:27
  Osborn challenged the long-standing belief that moderate alcohol consumption is beneficial for
• 11:32
  the heart, stating, "It's not good for your heart.
• 11:35
  It's not good for your brain.
• 11:37
  It's not good for your waistline." He pointed out that alcohol contributes to obesity, which
• 11:42
  he described as a "gateway disease" to numerous cancers and neurodegenerative conditions like
• 11:47
  Alzheimer's disease.
• 11:49
  The doctor explained that alcohol causes oxidative damage, a process where "free
• 11:55
  radicals" harm cells, tissues, and DNA, potentially leading to cancer formation.
• 12:01
  He stressed that every part of the body that alcohol comes into contact with, from the
• 12:05
  throat to the rectum, is exposed to this toxin.
• 12:10
  In his practice, Dr.
• 12:11
  Osborn has witnessed the detrimental effects of alcohol firsthand, particularly on the brain.
• 12:17
  He recounted a recent case involving a patient with alcoholism who suffered a severe fall,
• 12:22
  resulting in a large blood clot on the brain that required emergency surgery.
• 12:27
  Dr.
• 12:27
  Osborn noted that individuals with alcoholism often have compromised organ systems, leading
• 12:33
  to poorer outcomes in such medical scenarios.
• 12:37
  While Dr.
• 12:37
  Osborn strongly advises against alcohol use, he acknowledges the challenge of quitting for
• 12:43
  those who drink regularly.
• 12:45
  He suggests a gradual reduction approach, encouraging patients to cut their intake by
• 12:51
  half over a year, and then to continue reducing it.
• 12:55
  According to him, anyone consuming more than one drink per day may be considered dependent
• 13:01
  on alcohol.
• 13:03
  Dr.
• 13:03
  Osborn concluded his insights by stating, "I don't want it in my practice.
• 13:07
  I don't want it for my patients.
• 13:09
  I don't use it myself.
• 13:11
  It's bad.
• 13:11
  Get rid of it." His perspective underscores the broader movement towards recognizing and
• 13:16
  addressing the health risks associated with alcohol consumption.
