  Welcome to Morning Medical with Dr.
• 0:02
  Chow, your daily dose of the latest medical and health news from around the globe.
• 0:06
  I'm your host, Dr.
• 0:08
  Chi-Ming Chow, a family physician, general internist, and cardiologist based in Toronto,
• 0:13
  Canada.
• 0:14
  With a keen interest in medical informatics and a focus on ethnic differences in cardiovascular
• 0:19
  disease, I'm thrilled to bring you today's insights.
• 0:25
  Our first topic today is one that's often on the minds of many health-conscious individuals:
• 0:31
  is all processed food bad for you?
• 0:33
  Processed foods have become a staple in many diets worldwide, and they often get a bad rap.
• 0:39
  But is it fair to paint all processed foods with the same brush?
• 0:44
  To start, let's define what we mean by processed foods.
• 0:48
  Generally, any food that has been altered in some way during preparation is considered
• 0:53
  processed.
• 0:54
  This can range from simple processes like freezing or drying to more complex methods like
• 1:00
  adding preservatives or artificial flavors.
• 1:04
  Not all processed foods are created equal.
• 1:07
  Some, like pre-washed salad greens or canned beans, can be quite nutritious and convenient,
• 1:13
  offering essential nutrients with minimal additives.
• 1:16
  On the other hand, heavily processed foods, often referred to as ultra-processed foods,
• 1:22
  tend to be high in sugars, unhealthy fats, and sodium, which can contribute to various health
• 1:28
  issues when consumed in excess.
• 1:31
  The key is moderation and making informed choices.
• 1:35
  While it's best to limit the intake of ultra-processed foods, incorporating minimally
• 1:40
  processed options like whole-grain breads, canned tomatoes, and plain yogurt can fit well
• 1:46
  into a balanced diet.
• 1:47
  These foods provide convenience without compromising on nutritional value.
• 1:53
  It's important to be mindful of food labels, which can help you identify the level of
• 1:57
  processing and the ingredients used.
• 2:00
  Look for products with fewer ingredients and those that you recognize as whole foods.
• 2:05
  This can be a simple yet effective way to ensure you're making healthier choices.
• 2:11
  Ultimately, not all processed foods are detrimental to your health.
• 2:16
  By focusing on whole, minimally processed foods and being aware of what's in the products you
• 2:21
  consume, you can enjoy the convenience of processed foods while maintaining a healthy
• 2:26
  diet.
• 2:27
  Remember, it's about balance and making choices that support your overall well-being.
• 2:34
  Changing the clocks twice a year, a practice observed in many parts of the world, is
• 2:39
  increasingly becoming a topic of public health debate.
• 2:43
  Rébecca Robillard, an associate professor at the University of Ottawa and co-chair of the
• 2:48
  Canadian Sleep Research Consortium, has been vocal about the potential health implications
• 2:53
  of this biannual ritual.
• 2:56
  Professor Robillard suggests that the Atlantic provinces in Canada should consider adopting
• 3:01
  permanent daylight saving time.
• 3:04
  The argument here is rooted in the potential health benefits of maintaining a consistent
• 3:08
  time schedule year-round, which could mitigate some of the negative health effects associated
• 3:14
  with the current system.
• 3:16
  The practice of changing clocks can disrupt sleep patterns, leading to a variety of health
• 3:21
  issues.
• 3:22
  Sleep deprivation is linked to an increased risk of cardiovascular diseases, mood
• 3:27
  disorders, and decreased cognitive performance.
• 3:31
  These concerns are supported by a growing body of research indicating that even a small shift
• 3:36
  in time can significantly impact our biological rhythms.
• 3:41
  For many, the transition to and from daylight saving time results in a temporary misalignment
• 3:47
  between the biological clock and the external environment.
• 3:51
  This misalignment can affect sleep quality and duration, leading to sleep disorders and other
• 3:57
  health problems.
• 3:58
  Consequently, there is a push from some experts to eliminate the time change altogether.
• 4:04
  Professor Robillard's call for a permanent daylight saving time is part of a wider
• 4:09
  discussion on the need to prioritize public health in policy decisions.
• 4:14
  As more research highlights the health risks associated with clock changes, some regions are
• 4:19
  already moving towards abolishing this practice.
• 4:22
  For instance, several U.S.
• 4:24
  states have passed legislation to adopt permanent daylight saving time, pending federal
• 4:29
  approval.
• 4:31
  The debate over time change is not just about convenience but also about the broader
• 4:36
  implications for public health.
• 4:39
  As this conversation continues, it will be interesting to see how policymakers balance
• 4:44
  these concerns with other societal needs.
• 4:48
  A recent study published in BMJ Open Sport & Exercise Medicine has shed light on the
• 4:54
  potential benefits of a simple exercise routine that could significantly help in lowering blood
• 5:00
  pressure.
• 5:01
  The study focused on isometric exercise training, which involves muscle contractions
• 5:06
  without movement of the joints, such as wall squats.
• 5:10
  It found that even performing these exercises once a week can lead to meaningful reductions
• 5:15
  in resting blood pressure within just four weeks.
• 5:19
  The trial involved 100 inactive adults with normal to high-normal blood pressure, defined
• 5:25
  as a systolic reading between 120 and 140 millimeters of mercury.
• 5:31
  For the initial four weeks, participants engaged in lower-body isometric wall squats at
• 5:37
  home three times a week.
• 5:39
  These sessions were structured as four two-minute exercises, separated by two minutes
• 5:44
  of seated rest.
• 5:45
  The participants' efforts were monitored using heart-rate straps to ensure consistency.
• 5:52
  Results from the study were promising.
• 5:54
  After just four weeks, participants experienced an average drop of 9.5 points in their systolic
• 6:00
  blood pressure, with a noticeable decrease in diastolic pressure as well.
• 6:05
  The researchers then experimented with reducing the frequency of exercise to see its effects.
• 6:10
  Some participants continued with the exercises three times a week, while others reduced it to
• 6:16
  two, one, or completely stopped.
• 6:19
  Interestingly, those who maintained the exercise routine even once or twice a week were
• 6:25
  able to retain a significant portion of their blood pressure reductions.
• 6:29
  However, participants who ceased the exercises saw their blood pressure levels revert to
• 6:34
  baseline within four weeks, effectively losing the progress they had made.
• 6:40
  The study also highlighted that only the group that continued exercising three times weekly
• 6:45
  retained improvements in other cardiovascular metrics such as total peripheral resistance,
• 6:51
  heart rate variability, and reflex sensitivity.
• 6:55
  These metrics are crucial as they measure the efficiency of blood flow and the nervous
• 6:59
  system's ability to regulate blood pressure.
• 7:03
  Dr.
• 7:03
  Aseem Malhotra, a cardiologist and metabolic health specialist, commented on the study,
• 7:09
  noting that such exercises offer a cost-effective way to improve cardiovascular
• 7:14
  health.
• 7:15
  While he was not involved in the study, Dr.
• 7:18
  Malhotra emphasized that physical movement is just one aspect of maintaining good health, and
• 7:24
  dietary changes can also significantly impact blood pressure.
• 7:28
  The study's cohort was relatively modest, consisting of 100 generally healthy,
• 7:34
  non-smoking adults who were not on blood pressure medications.
• 7:38
  Therefore, these findings might not directly apply to individuals with diagnosed
• 7:43
  hypertension, older adults with mobility issues, or those already on heart medications.
• 7:49
  Moreover, the maintenance phase of the study lasted only four weeks, suggesting that
• 7:54
  longer-term research is needed to confirm if a once-weekly exercise session can sustain blood
• 8:00
  pressure reductions over the long term.
• 8:03
  In summary, this study offers an intriguing glimpse into how simple, low-cost exercises
• 8:09
  like wall squats could potentially benefit cardiovascular health, especially for those
• 8:15
  looking to manage their blood pressure.
• 8:17
  While more research is needed, the findings suggest that even minimal exercise can have
• 8:22
  substantial health benefits, making it an accessible option for many.
• 8:28
  Today, we're shedding light on a distressing situation affecting patients in the United
• 8:33
  Kingdom, particularly those with multiple sclerosis.
• 8:37
  Jill Kenning, a woman from Coleraine in County Londonderry, has been living with "horrific
• 8:43
  pain" due to a shortage of the drug Nabilone, which she has relied on for managing her
• 8:48
  condition.
• 8:49
  For 17 of the 18 years since her diagnosis, Nabilone has been essential in helping her lead
• 8:55
  a normal life, but now, she finds herself bedridden after running out of the medication.
• 9:01
  This shortage is part of a larger issue affecting the United Kingdom, with Northern
• 9:06
  Ireland's devolved health department confirming that supplies of Nabilone are disrupted across
• 9:12
  the nation.
• 9:13
  The drug, crucial for many patients like Jill, will not be available until December, leaving
• 9:19
  those affected in a dire situation.
• 9:22
  Jill Kenning describes her pain as if being "stabbed with a hot poker" in her eye, a vivid
• 9:28
  depiction of the severity of her condition without Nabilone.
• 9:32
  Despite being prescribed alternative medications, these have not been effective,
• 9:37
  leading to a significant decline in her health and requiring hospital stays.
• 9:42
  The Department of Health in Northern Ireland has acknowledged the shortage, stating that
• 9:47
  both licensed doses of Nabilone are out of stock.
• 9:51
  The disruption began with the 1 milligram capsules in July, and more recently, the 0.25
• 9:57
  milligram strength also became unavailable.
• 10:00
  They are working with the United Kingdom's Department of Health and Social Care to manage
• 10:04
  this situation, and guidance has been issued to healthcare professionals on alternative
• 10:09
  treatments, including unlicensed imports where possible.
• 10:14
  This situation underscores the broader issue of medicine shortages in the United Kingdom.
• 10:20
  According to MIMS, an industry reference guide, the average number of drugs in short supply has
• 10:27
  increased this year, reaching 157 this week.
• 10:31
  This trend is not only alarming for patients but also poses a significant challenge for
• 10:36
  healthcare providers who strive to deliver consistent care.
• 10:41
  For patients like Jill Kenning, the uncertainty and pain are overwhelming.
• 10:47
  She voices her concern not just for herself but for all patients dependent on Nabilone.
• 10:52
  Jill emphasizes the need for better preparation and communication regarding such disruptions,
• 10:58
  as the lack of access to essential medication profoundly impacts her quality of life.
• 11:04
  Multiple sclerosis affects the nerves in the brain and spinal cord, where the protective
• 11:09
  myelin sheath is mistakenly attacked by the immune system, disrupting communication between
• 11:15
  the brain and the body.
• 11:17
  This can lead to a variety of symptoms, including the severe pain that Jill
• 11:21
  experiences.
• 11:23
  In light of these challenges, it's crucial for affected individuals to communicate with their
• 11:28
  healthcare providers to explore available treatment options.
• 11:32
  The Department of Health advises patients to discuss their concerns with their specialist
• 11:37
  healthcare teams to find suitable alternatives during this supply disruption.
• 11:43
  In our final segment today, we're turning our focus to a heated discussion happening in
• 11:48
  Manitoba, Canada, where over 60 emergency care doctors are urging the provincial government to
• 11:55
  pause discussions on a virtual care initiative.
• 11:58
  This initiative aims to reduce wait times in emergency rooms by potentially allowing
• 12:03
  out-of-province doctors to assess patients virtually.
• 12:06
  However, this proposal has been met with significant resistance from the medical
• 12:11
  community.
• 12:12
  The emergency physicians, particularly those at Health Sciences Centre and St.
• 12:17
  Boniface Hospital, have expressed their concerns in a letter to Manitoba's health
• 12:22
  minister.
• 12:23
  They argue that assessing patients virtually could compromise patient care, as remote
• 12:28
  assessments might not always suffice without an in-person examination.
• 12:33
  The doctors are emphasizing the need for meaningful consultation with front-line
• 12:37
  clinicians before moving forward with any such initiative.
• 12:42
  Manitoba's health minister, Uzoma Asagwara, has stated that the province is still in the
• 12:47
  consultation phase and no decisions have been made yet.
• 12:51
  The minister assures that any move forward would involve input from front-line providers
• 12:56
  to ensure it fits Manitoba's needs.
• 12:59
  While the potential for virtual assessments to benefit some patients by reducing wait times is
• 13:05
  recognized, the primary concern remains that this might not translate into quicker access to
• 13:10
  the necessary care.
• 13:12
  The doctors are adamant about the importance of transparency and comparison with other
• 13:18
  potential solutions that could address emergency room wait times more effectively.
• 13:23
  They have requested an urgent meeting with the health minister to discuss the proposed model,
• 13:27
  raise their concerns, and explore alternative options before any commitments are made.
• 13:33
  In response to these concerns, Doctors Manitoba has echoed the sentiment that significant
• 13:39
  changes in healthcare should not come as a surprise to front-line physicians.
• 13:44
  They stress the importance of including these professionals in the decision-making process
• 13:48
  from the outset to ensure that any new initiatives are beneficial and practical for
• 13:54
  both patients and providers.
• 13:56
  As we conclude today's episode, it's clear that the debate over virtual care initiatives in
• 14:02
  Manitoba highlights the complexities of integrating new technologies into healthcare
• 14:07
  systems.
• 14:08
  Balancing innovation with practical, patient-centered care remains a significant
• 14:14
  challenge.
