  Welcome back to another episode of Morning Medical with Dr.
• 0:03
  Chow, your daily update on the latest in medical and health news from around the globe.
• 0:09
  I'm your host, Dr.
• 0:11
  Chi-Ming Chow.
• 0:12
  Today, we're diving into a fascinating new study that challenges some long-held beliefs
• 0:17
  about how we assess cardiovascular risk.
• 0:22
  For many years, we've relied heavily on Body Mass Index, or BMI, as a key measure for
• 0:28
  assessing health risks related to body weight.
• 0:31
  However, a recent pooled analysis of cohort studies is turning that notion on its head.
• 0:36
  Conducted by Michael Blaha and his colleagues from the Johns Hopkins Ciccarone Center for the
• 0:41
  Prevention of Cardiovascular Disease, this analysis suggests that waist circumference and
• 0:47
  the waist-to-hip ratio might be more indicative of cardiovascular disease risk than BMI alone.
• 0:54
  The study, which was published in the Journal of the American College of Cardiology, examined
• 1:00
  data from over 259,000 participants across 15 different cohort studies primarily based in the
• 1:08
  United States.
• 1:09
  What they found was rather surprising: even individuals with a normal BMI could have a high
• 1:15
  waist circumference or waist-to-hip ratio, both of which are linked to a significantly higher
• 1:21
  risk of cardiovascular disease.
• 1:24
  In fact, the study reported that people with a normal weight but with a large waist
• 1:28
  circumference or a high waist-to-hip ratio faced a 15 to 50 percent increased risk of
• 1:34
  various heart disease outcomes over a 20-year period.
• 1:38
  This includes risks for conditions such as myocardial infarction, stroke, heart failure,
• 1:43
  and even atrial fibrillation.
• 1:46
  Interestingly, the study also highlighted that individuals with obesity but with a small waist
• 1:52
  circumference had clinical outcomes similar to those of normal-weight individuals.
• 1:58
  This suggests that where fat is distributed in the body may be more crucial than the amount of
• 2:04
  fat itself when it comes to assessing cardiovascular risk.
• 2:08
  The American Medical Association had already advised against using BMI as a standalone
• 2:14
  diagnostic tool back in 2023, due to its limitations in accurately reflecting body fat
• 2:20
  percentage.
• 2:21
  This study reinforces that recommendation, suggesting that measurements like waist
• 2:26
  circumference and waist-to-hip ratio should be integrated into routine cardiovascular risk
• 2:31
  assessments.
• 2:33
  However, there are still some questions that remain unanswered.
• 2:37
  For instance, how often should these measures of central adiposity be taken, and would
• 2:42
  reducing central adiposity directly impact cardiovascular disease risk?
• 2:48
  These are areas that require further research.
• 2:51
  The study also pointed out sex differences, noting that women with obesity but a low
• 2:57
  waist-to-hip ratio were still at higher risk compared to those with normal weight and low
• 3:02
  waist-to-hip ratio, although their risk was lower than women with both obesity and a high
• 3:08
  waist-to-hip ratio.
• 3:10
  It's clear that this study opens up new avenues for understanding cardiovascular risk.
• 3:15
  As always, it's important to consult with healthcare professionals to determine the best
• 3:20
  approach for individual health assessments.
• 3:23
  Stay tuned for more updates on this topic as new research emerges.
• 3:29
  Our next story delves into the intriguing side effects of a class of drugs that have been
• 3:34
  making waves in both the diabetes and weight-loss landscapes: the glucagon-like
• 3:39
  peptide-1 receptor agonists, commonly known as GLP-1 receptor agonists.
• 3:47
  These medications, such as semaglutide, marketed under names like Ozempic and Wegovy,
• 3:53
  have been praised for their benefits in managing type 2 diabetes and aiding weight
• 3:58
  loss.
• 4:00
  However, it's their side effects that are now capturing a lot of attention, some even earning
• 4:05
  catchy nicknames like "Ozempic teeth."
• 4:08
  One of the most frequently reported side effects of GLP-1 receptor agonists is
• 4:12
  gastrointestinal in nature, including nausea, vomiting, and diarrhea.
• 4:18
  These symptoms have been well-documented since the initial approvals of these drugs by the
• 4:22
  United States Food and Drug Administration for diabetes management, appearing consistently in
• 4:26
  clinical trials and systematic reviews.
• 4:30
  Another concerning issue is muscle mass loss.
• 4:33
  It's been observed that patients on GLP-1 drugs often lose lean muscle mass along with fat.
• 4:40
  Some studies suggest that increasing protein intake might help mitigate this loss, but it's
• 4:46
  still a significant consideration for those using these medications.
• 4:50
  The term "Ozempic teeth" has emerged due to reports of oral health issues among users,
• 4:57
  including dry mouth, sensitivity, and gum inflammation.
• 5:01
  Experts have linked these problems to dehydration, a known side effect of GLP-1
• 5:06
  receptor agonists.
• 5:08
  There's also a phenomenon known as "Ozempic personality," where patients experience an
• 5:14
  emotional flattening.
• 5:16
  This involves a dulled response not just towards food, but also to other pleasurable
• 5:21
  activities like listening to music, dancing, or even engaging in social interactions.
• 5:27
  Hair loss has also been flagged as a potential side effect, appearing more frequently in women
• 5:32
  than men according to early research and clinical trial data.
• 5:37
  Of more serious concern is the risk of blindness.
• 5:40
  The European Medicines Agency warned about a rare, potentially severe side effect known as
• 5:46
  non-arteritic anterior ischemic optic neuropathy, which can lead to vision loss.
• 5:52
  While this affects a small number of users, it illustrates the need for awareness and
• 5:57
  monitoring.
• 5:58
  Other eye conditions, such as neovascular age-related macular degeneration and diabetic
• 6:04
  retinopathy, have also been associated with these drugs, highlighting the importance of
• 6:09
  regular ophthalmic check-ups for those on GLP-1 receptor agonists.
• 6:15
  Gallbladder issues, including gallstones and inflammation known as cholecystitis, are
• 6:20
  additional risks, albeit with a relatively small absolute risk.
• 6:24
  Yet, they remain a topic of discussion among healthcare providers.
• 6:29
  In 2024, the United States Food and Drug Administration added a warning about the risk
• 6:35
  of pulmonary aspiration during surgery for those on GLP-1 drugs.
• 6:41
  This has led to a debate among anesthesiologists about whether patients should
• 6:46
  pause these medications before undergoing surgery.
• 6:50
  Thyroid tumors are another potential risk.
• 6:53
  While the link between GLP-1 drugs and thyroid cancer has been noted, recent studies suggest
• 6:58
  that the perceived risk might be due to increased surveillance rather than an actual
• 7:03
  increase in cancer incidence.
• 7:06
  Lastly, GLP-1 drugs may interfere with medical imaging, particularly cancer PET-CT scans, by
• 7:14
  affecting the uptake of tracers, which could complicate the interpretation of these scans.
• 7:21
  Taylor Farms, a major food producer, is in the spotlight again, this time recalling several
• 7:26
  jalapeno-containing products due to potential salmonella contamination.
• 7:31
  This recall comes just weeks after the company had to pull its iceberg lettuce off the shelves
• 7:36
  over concerns related to a cyclospora outbreak.
• 7:40
  The affected products include popular items like taco dip, guacamole, salsa, and pico de
• 7:46
  gallo.
• 7:48
  The recall was initiated after Coast Citrus Distributors, a supplier of fresh jalapenos
• 7:55
  from Sinaloa, Mexico, announced a voluntary recall of their products.
• 8:00
  The United States Food and Drug Administration and the Centers for Disease Control and
• 8:05
  Prevention are investigating this salmonella outbreak, which has been linked to fresh
• 8:10
  jalapenos.
• 8:12
  The investigation involves state and local partners as they try to pinpoint the source of
• 8:17
  the contamination.
• 8:19
  Taylor Farms has responded by stating that they are no longer sourcing jalapenos from the
• 8:24
  implicated grower and have switched to alternative suppliers.
• 8:28
  To date, no illnesses have been reported from Taylor Farms' products containing jalapenos,
• 8:33
  but the company is taking precautions to prevent any potential health risks.
• 8:38
  The recalled products were distributed across 26 states, including Alabama, Florida, New
• 8:44
  York, and Texas.
• 8:46
  They have a "best if used by" date up to August 16, 2026.
• 8:52
  Retailers such as Walmart, Target, Trader Joe’s, and Whole Foods have been affected by
• 8:57
  the recall.
• 8:59
  Consumers who have purchased these products are advised to discard them immediately and can
• 9:03
  obtain refunds at the point of purchase.
• 9:07
  Symptoms of salmonella infection can include diarrhea, fever, severe vomiting, dehydration,
• 9:14
  and stomach cramps.
• 9:17
  While most people recover within a week, severe cases can occur, particularly in young
• 9:22
  children, older adults, and those with weakened immune systems, who might require
• 9:26
  hospitalization.
• 9:29
  This incident adds to a challenging period for Taylor Farms, which was also linked to a
• 9:34
  cyclospora outbreak connected to shredded lettuce.
• 9:37
  The company had previously recalled iceberg lettuce from central Mexico, suspected to be
• 9:43
  the source of the cyclospora outbreak that affected Taco Bell and other restaurants.
• 9:49
  As investigations continue, it's a reminder of the critical importance of food safety
• 9:54
  protocols and the impact of such recalls on both public health and business operations.
• 10:00
  Public health officials emphasize the need for vigilance in food handling and thorough checks
• 10:05
  on supply chains to prevent such outbreaks.
• 10:10
  Our final story today takes us to the Democratic Republic of Congo, where the world
• 10:14
  is witnessing the fastest-growing Ebola outbreak in recorded history.
• 10:20
  According to data released recently, at least 2,000 people have succumbed to the disease
• 10:26
  since the outbreak began, marking a grim milestone in the ongoing health crisis.
• 10:32
  This outbreak, which has reached 4,381 confirmed cases, surpasses previous records in
• 10:39
  its rapid spread.
• 10:41
  It began months earlier than initially declared, with health authorities now tracing
• 10:46
  its origins back to February of this year, though it was officially announced in May.
• 10:51
  The situation in eastern Congo's Ituri province is dire, exacerbated by challenges such as
• 10:56
  rebel conflicts, poor infrastructure, and work stoppages due to payment issues.
• 11:02
  These conditions have severely hampered the urgent response needed to control the outbreak.
• 11:08
  The outbreak is the second largest in history, following the 2014-2016 West Africa outbreak,
• 11:14
  which had over 28,000 cases and resulted in more than 11,000 deaths.
• 11:19
  However, the current outbreak has a higher case fatality rate of 45.9 percent, compared to the
• 11:25
  39.6 percent from the previous largest outbreak.
• 11:29
  What makes this outbreak particularly challenging is that it's caused by the rare
• 11:34
  Bundibugyo virus, for which there are no approved vaccines or treatments.
• 11:39
  Clinical trials are underway, but the lack of readily available medical interventions means
• 11:44
  the focus remains on identifying and isolating cases to prevent further spread.
• 11:50
  The World Health Organization has noted that early in the outbreak, some cases were
• 11:55
  misdiagnosed as malaria or typhoid, delaying an effective response.
• 12:00
  Despite efforts to restrict public gatherings and close the main airport in Ituri, the virus
• 12:05
  continues to outpace containment efforts.
• 12:09
  In addition to logistical challenges, misinformation and distrust of outsiders have
• 12:15
  complicated community engagement efforts.
• 12:18
  These factors make it difficult to educate the public about the virus and the necessary safety
• 12:23
  measures.
• 12:25
  As we reflect on this unfolding tragedy, it's a stark reminder of the importance of global
• 12:30
  health vigilance and preparedness.
• 12:33
  The ongoing efforts by healthcare workers and organizations on the ground are crucial in the
• 12:38
  fight against this deadly outbreak.
• 12:41
  That concludes today's episode of Morning Medical with Dr.
• 12:45
  Chow.
• 12:46
  Thank you for tuning in.
• 12:48
