  Welcome to "Morning Medical with Doctor Chow," your go-to source for the latest in medical and
• 0:05
  health news from around the globe.
• 0:08
  I'm Doctor Chi-Ming Chow, your host for today's episode.
• 0:12
  As always, we're diving into the most pressing health topics with the help of artificial
• 0:17
  intelligence, bringing you the news you need to know.
• 0:21
  Today, we're going to discuss a controversial new COVID-19 vaccination rollout in Alberta,
• 0:28
  Canada.
• 0:29
  As of October 1st, the government of Alberta has begun a new phase in its COVID-19 vaccine
• 0:37
  rollout.
• 0:38
  This new plan, however, has sparked quite a bit of debate.
• 0:42
  It's aimed at providing free COVID-19 and flu shots to those considered to be at high risk.
• 0:48
  This includes seniors living in long-term care facilities, individuals aged 65 and over,
• 0:54
  health-care workers, and those with underlying medical conditions.
• 0:58
  These vulnerable groups can now book appointments to receive their vaccinations.
• 1:04
  However, the process hasn't been smooth.
• 1:07
  Many Albertans, like health-care worker Nicole Perry, have found the new system difficult to
• 1:12
  navigate.
• 1:13
  Perry spent days trying to pre-order a vaccine and book an appointment through the online
• 1:18
  system, only to face high call volumes and busy signals when seeking assistance from the 811
• 1:24
  health line.
• 1:25
  "Every time I called, I just got a message saying, 'We're extremely busy right now,'" she
• 1:30
  shared, expressing her frustration with the system.
• 1:34
  Adding to the controversy, the government plans to charge the majority of Albertans one hundred
• 1:39
  Canadian dollars for the newly formulated COVID-19 shot.
• 1:43
  This decision was made in response to concerns about vaccine waste and high costs.
• 1:48
  For those who have to pay, appointments won't be available until October 20th.
• 1:54
  Perry also mentioned her young daughter, who won't be eligible for a vaccine appointment
• 1:59
  until later this month, raising questions about the accessibility and communication of the new
• 2:05
  system.
• 2:05
  The new program has also prompted concern from pharmacies.
• 2:10
  Mohamed Elfishawi, who owns two pharmacies in Edmonton, noted that pharmacies must order
• 2:16
  vaccines directly from suppliers, which increases costs.
• 2:20
  At his clinics, the vaccine would cost around twenty Canadian dollars more than the one
• 2:24
  hundred dollars charged by public health clinics.
• 2:27
  Elfishawi expressed concerns that this could limit access for some patients who aren't
• 2:33
  accustomed to booking appointments online or over the phone, and he called for a rollback of
• 2:38
  the program.
• 2:40
  Experts like Dawn Bowdish, an immunologist and professor of medicine at McMaster University,
• 2:45
  have voiced worries about the implications of this policy.
• 2:49
  Bowdish highlighted that when people have to pay for vaccines, they might perceive them as
• 2:54
  less important.
• 2:55
  This could lead to inequities where those who can afford the vaccine receive it, while those
• 3:00
  who cannot are left vulnerable.
• 3:03
  Such a policy makes Alberta the only Canadian province without universal free access to
• 3:09
  COVID-19 shots.
• 3:12
  Every October, health experts remind us that it's time to get a flu vaccination.
• 3:18
  This year is no different, and the call to action is perhaps even more urgent.
• 3:23
  Last winter, the United States experienced the highest number of flu-related child deaths in
• 3:28
  fifteen years.
• 3:30
  Because of this, pediatricians are particularly urging parents to get their children
• 3:34
  vaccinated.
• 3:36
  October is considered the ideal month to get a flu shot.
• 3:40
  This timing is crucial because flu cases typically begin to rise in November.
• 3:45
  "The best time is today.
• 3:47
  If you haven't already had it, get it," says Doctor Laura Riley from the American College of
• 3:52
  Obstetricians and Gynecologists.
• 3:55
  She emphasizes the importance of getting vaccinated now to ensure protection as the flu
• 4:00
  season ramps up.
• 4:02
  For those who are not fans of needles, there's an alternative this year.
• 4:06
  For the first time, some people can try vaccinating themselves at home using the nasal
• 4:11
  spray vaccine FluMist.
• 4:13
  This option is available for certain adults and children, making it easier for those who may
• 4:18
  have needle phobia or prefer the convenience of home vaccination.
• 4:23
  The Centers for Disease Control and Prevention, along with major medical societies, recommend
• 4:29
  that just about everyone aged six months and older should receive a yearly flu vaccination.
• 4:35
  Despite ongoing misinformation about vaccines, the flu recommendations remain unchanged.
• 4:41
  The flu is particularly dangerous for individuals aged sixty-five and older, pregnant
• 4:46
  women, young children, and people of any age who have chronic health conditions such as
• 4:50
  asthma, diabetes, heart disease, or weakened immune systems.
• 4:56
  Flu vaccines play a critical role in preventing severe illness and hospitalization.
• 5:02
  While they may not stop all infections, they significantly reduce the risk of severe
• 5:07
  outcomes.
• 5:09
  Last year's flu season was particularly harsh, with the Centers for Disease Control and
• 5:14
  Prevention counting two hundred eighty child deaths due to flu-related complications.
• 5:20
  Alarmingly, nearly half of these children had no prior health issues, and about ninety
• 5:26
  percent were not fully vaccinated.
• 5:30
  Flu vaccination is also highly recommended during pregnancy.
• 5:34
  Doctor Riley explains that a severe case of the flu can lead to hospitalization for pregnant
• 5:40
  women and increase the risk of premature birth.
• 5:44
  Additionally, the flu shot provides protection to newborns, who are especially vulnerable to
• 5:49
  the flu.
• 5:51
  Years of research have shown that flu vaccination during pregnancy is safe for both
• 5:56
  the mother and the baby.
• 5:59
  When it comes to choosing a flu vaccine, there are several options.
• 6:02
  High-dose shots and those with special immune boosters are tailored for individuals aged
• 6:08
  sixty-five and older.
• 6:10
  However, if these are not readily available, a regular all-ages flu shot is still beneficial.
• 6:17
  For those who prefer not to get a shot, the nasal spray FluMist is an option for people
• 6:23
  aged two to forty-nine.
• 6:26
  The new at-home option for FluMist is a significant development.
• 6:30
  It's available for certain adults who qualify based on their age and a medical questionnaire.
• 6:35
  Once deemed eligible, they can receive FluMist shipped to their home with instructions on how
• 6:40
  to administer it.
• 6:41
  The Food and Drug Administration approved this home administration option last year, and it is
• 6:46
  currently available in thirty-four states, with hopes to expand further.
• 6:51
  Regarding cost, flu vaccines are generally free under Medicare, Medicaid, and most private
• 6:56
  insurance plans if an in-network provider is used.
• 7:00
  Local health departments may also offer free or low-cost vaccinations for those who qualify.
• 7:06
  However, for the at-home FluMist option, while insurance rules should apply, there might be an
• 7:11
  out-of-pocket delivery fee.
• 7:14
  Interestingly, flu and COVID-19 vaccines can be administered simultaneously.
• 7:20
  Doctor Philip Huang of Dallas Health and Human Services confirms that getting both vaccines at
• 7:27
  the same time is safe and convenient.
• 7:30
  However, there might still be challenges in accessing COVID-19 vaccines, particularly for
• 7:35
  children, due to recent changes in federal recommendations.
• 7:41
  Our next topic takes us to the skies, where a new study has highlighted a rising trend in
• 7:47
  in-flight medical events.
• 7:49
  This retrospective cohort study, reported by Nicole Lou from MedPage Today, involved data
• 7:56
  from eighty-four airlines worldwide.
• 8:00
  It found that the overall incidence of in-flight medical events is thirty-nine per one
• 8:04
  million passenger enplanements.
• 8:07
  That's quite a significant number, considering the vast number of people who fly every year.
• 8:13
  Interestingly, aircraft diversion—the need to land a plane for medical reasons—occurred in
• 8:20
  only 1.7 percent of these events.
• 8:23
  The study, led by Doctor Alexandre Rotta from Duke University Medical Center, reported that
• 8:30
  the most common reasons for diversion were neurologic and cardiac emergencies.
• 8:35
  These accounted for forty-one percent and twenty-seven percent of diversions,
• 8:39
  respectively.
• 8:41
  One of the key findings of this study is the role of ground-based medical support centers.
• 8:46
  These centers provide real-time medical guidance, which has allowed for more
• 8:51
  conservative management of in-flight medical events.
• 8:54
  In fact, in-flight advice and treatment were sufficient in fifty-three percent of cases.
• 8:59
  It's fascinating to note that only about one in three medical events had the involvement of a
• 9:04
  passenger volunteer with a medical background.
• 9:08
  The study also identified certain factors that increased the likelihood of plane diversion.
• 9:14
  Suspected strokes, acute cardiac emergencies, and altered mental status were the top reasons.
• 9:21
  Additionally, the presence of a physician volunteer and ultralong-haul flights were
• 9:26
  linked to higher odds of diversion.
• 9:29
  This highlights the importance of having structured response systems and proactive
• 9:34
  preparedness in place to ensure passenger safety.
• 9:38
  The study's authors also pointed out that the growing trend of medical tourism might
• 9:44
  contribute to the frequency of in-flight medical events.
• 9:48
  Passengers traveling soon after medical procedures or with complex health conditions
• 9:53
  could be more susceptible to medical issues during flights.
• 9:57
  The unique stressors of air travel, such as restricted mobility and reduced cabin pressure,
• 10:03
  can also exacerbate pre-existing conditions.
• 10:07
  An accompanying editorial by Doctor William Brady from the University of Virginia and
• 10:12
  Doctor Jose Nable from Georgetown University emphasized the need for proper airline
• 10:17
  planning.
• 10:18
  This includes equipping aircraft with the necessary medical supplies and developing
• 10:23
  diversion policies.
• 10:25
  They also suggested that the study could help determine the contents of on-board medical kits
• 10:30
  and guide regulations regarding in-flight medical emergencies.
• 10:35
  In terms of medical interventions, the study reported that medical kits were accessed in
• 10:40
  twenty-three percent of in-flight events.
• 10:42
  Non-narcotic analgesics and antiemetics were the most frequently administered drugs.
• 10:48
  Cardiopulmonary resuscitation was performed in a small fraction of cases, while the use of
• 10:54
  automated external defibrillators was rare.
• 10:57
  The study authors noted that oxygen available on planes is primarily intended for flight
• 11:03
  attendants during depressurization emergencies, not for medical use.
• 11:09
  For passengers at high risk of hypoxemia, the study recommends traveling with an approved
• 11:14
  oxygen concentrator.
• 11:16
  This is crucial even if they do not require supplemental oxygen at sea level.
• 11:21
  The findings were based on data from the MedAire database, which provided insights from
• 11:26
  over seventy-seven thousand in-flight medical events reported between January 2022 and
• 11:31
  December 2023.
• 11:34
  The median age of affected passengers was forty-three years, with more than half being
• 11:39
  women.
• 11:40
  Most incidents occurred on international flights, particularly long-haul routes.
• 11:45
  While some patients were treated on-site and released, others required hospital transport,
• 11:49
  and unfortunately, a small percentage succumbed to their conditions, with acute cardiac
• 11:55
  emergencies being the leading cause of death.
• 11:58
  Although the study acknowledges limitations due to its retrospective nature and potential data
• 12:03
  entry errors, it provides vital insights into the frequency and management of in-flight
• 12:09
  medical events.
• 12:11
  As air travel continues to grow, so does the importance of being prepared to handle medical
• 12:16
  emergencies at thirty-five thousand feet.
• 12:21
  Our final topic today delves into the intriguing realm of wearable technology and its
• 12:27
  potential role in managing rheumatoid arthritis, or RA.
• 12:32
  A recent study suggests that popular activity trackers, like the Apple Watch, Fitbit, and
• 12:37
  Oura Ring, could be instrumental in predicting RA flares before they become clinically
• 12:42
  apparent.
• 12:43
  This study, conducted by Doctor Robert P.
• 12:47
  Hirten and his team at the Icahn School of Medicine at Mount Sinai in New York City, found
• 12:52
  that changes in physical activity and heart rate data, collected by these devices, were
• 12:58
  predictive of RA flares up to four weeks in advance.
• 13:02
  This means that individuals with RA could potentially receive early warnings about
• 13:07
  impending flares, allowing for proactive management of their condition.
• 13:12
  The study involved fifty-three RA patients who wore devices such as the Apple Watch, Fitbit,
• 13:18
  or Oura Ring for an average of one hundred fifty-four days.
• 13:22
  The researchers discovered that a model combining step counts and various heart rate
• 13:27
  measures predicted RA flares with remarkable accuracy.
• 13:32
  Specifically, the model had a 97 percent accuracy rate for predicting both symptomatic
• 13:38
  flares and inflammatory flares, the latter being identified by elevations in C-reactive
• 13:44
  protein without increased pain or tenderness.
• 13:48
  These findings align with previous studies that have linked physical activity and autonomic
• 13:52
  function with disease activity in RA.
• 13:55
  The researchers noted that individuals with active RA tend to have lower heart rate
• 14:00
  variability, or HRV, compared to those with inactive disease.
• 14:05
  Similarly, higher heart rates and resting heart rates have been observed in RA patients
• 14:11
  compared to healthy controls, reflecting autonomic dysfunction.
• 14:16
  One of the exciting aspects of this study is the continuous monitoring capability of
• 14:22
  wearable devices.
• 14:23
  Unlike traditional methods that rely on periodic measurements, these devices offer
• 14:28
  near-continuous tracking of physiological parameters related to RA activity.
• 14:35
  This continuous data collection provides a valuable opportunity to monitor and predict
• 14:40
  disease activity more accurately.
• 14:43
  However, it's important to note that the study was reported as a preprint manuscript and
• 14:47
  should be considered preliminary until it undergoes peer review.
• 14:51
  Furthermore, while the accuracy of the predictive model is impressive, the researchers
• 14:56
  caution that such accuracy might not be maintained when applied to different groups of
• 15:01
  patients.
• 15:02
  They also highlighted practical challenges, such as adherence to consistent device use,
• 15:08
  which can vary due to comfort, user engagement, and digital literacy.
• 15:14
  The study also had some limitations, including a small sample size and the use of different
• 15:19
  devices that may vary in data capture accuracy.
• 15:23
  Additionally, adjustments for medication use during the study were not made, and flare
• 15:28
  detection may have been inconsistent.
• 15:31
  Despite these limitations, the potential for wearable devices to aid in the management of RA
• 15:37
  is promising and warrants further investigation.
• 15:41
  As we wrap up today's episode, it's clear that technology continues to make significant
• 15:46
  strides in the field of medicine, offering new ways to monitor and manage chronic conditions
• 15:51
  like rheumatoid arthritis.
