  Today, we're diving into some pressing issues affecting public health globally.
• 0:19
  Let's start with a concerning report that has brought to light the alarming rise in deaths
• 0:24
  linked to wildfire smoke.
• 0:26
  According to a major global report published in The Lancet, deaths from wildfire smoke in
• 0:31
  Canada have surged by approximately 275 percent since the early 2000s.
• 0:38
  This dramatic increase is not just a statistic; it underscores the urgent need for more serious
• 0:44
  climate action.
• 0:46
  Ian Culbert, the executive director of the Canadian Public Health Association, emphasized
• 0:52
  that climate change and its impact on health are immediate concerns.
• 0:56
  He pointed out that the effects are measurable today and not just something that will affect
• 1:01
  us decades from now.
• 1:03
  The report indicates that there were about 4,000 annual deaths associated with wildfire
• 1:09
  smoke between 2021 and 2025, a significant rise from the average of 1,050 annual deaths
• 1:16
  recorded between 2003 and 2012.
• 1:20
  This increase coincides with some of the worst wildfire seasons on record in Canada, with
• 1:26
  British Columbia, Alberta, the Northwest Territories, and northern Ontario being
• 1:31
  particularly hard-hit.
• 1:33
  Smoke from these fires doesn't just affect those living near them.
• 1:37
  It travels great distances, creating hazardous air quality conditions in major urban centers.
• 1:43
  Scott Weichenthal, a professor in the department of epidemiology and biostatistics at
• 1:49
  McGill University, noted that the health impacts of wildfire smoke are far-reaching and
• 1:54
  more severe than the death toll numbers alone suggest.
• 1:58
  The primary concern is PM 2.5, or fine particulate matter, which can penetrate deep
• 2:05
  into the lungs and enter the bloodstream, causing premature deaths.
• 2:09
  But the fires release a range of other harmful substances, many of which are known
• 2:14
  carcinogens.
• 2:16
  During intense wildfire seasons, spikes in air pollutants like PM 2.5, ozone, and nitrogen
• 2:23
  dioxide are common, leading to increased hospitalizations for heart and lung problems,
• 2:29
  especially in individuals with pre-existing conditions.
• 2:33
  The report also highlights the broader environmental impact, noting that Canada lost
• 2:39
  5.2 million hectares of tree cover in 2024, a 148 percent increase from 2016.
• 2:47
  This loss is primarily due to wildfires, which exacerbate heat issues by removing essential
• 2:53
  tree cover that helps regulate temperatures.
• 2:56
  As temperatures rise, the risk of heat-related health issues also increases.
• 3:02
  Vulnerable populations, including older adults, young children, and those with pre-existing
• 3:08
  conditions, face the greatest risks.
• 3:11
  The ongoing El Niño event is expected to worsen these conditions by creating hotter and drier
• 3:17
  weather.
• 3:18
  The Canadian Public Health Association is calling for stronger public health
• 3:22
  interventions, urging all levels of government to take action to protect communities from the
• 3:28
  impacts of climate change.
• 3:30
  One key recommendation is the establishment of a permanent climate and health adaptation fund
• 3:36
  to ensure sustained capacity to deal with these ongoing challenges.
• 3:42
  In a recent study conducted in the United Kingdom, researchers have discovered a
• 3:47
  concerning link between industrial water pollution and an increased risk of developing
• 3:52
  progressive supranuclear palsy, or P.S.P.
• 3:56
  This rare and severe neurodegenerative disorder is now being associated with living near
• 4:02
  industrial facilities that emit a variety of pollutants, including heavy metals and
• 4:07
  pesticides.
• 4:09
  The study, which analyzed data from U.K.
• 4:11
  Biobank participants, found that the risk of P.S.P.
• 4:15
  was significantly higher for those residing closer to industrial sites known for polluting
• 4:21
  water supplies.
• 4:22
  These sites included wastewater treatment plants, chemical plants, and thermal power
• 4:27
  stations, all of which release various harmful substances into the environment.
• 4:33
  Specifically, the research highlighted the increased risk associated with pollutants such
• 4:38
  as heavy metals, pesticides, and both organic and inorganic pollutants.
• 4:44
  The odds ratios for developing P.S.P.
• 4:47
  were notably higher for individuals living near these facilities, with risk decreasing as the
• 4:53
  distance from the source of pollution increased.
• 4:56
  Dr.
• 4:57
  Charlie Weige Zhao from Harvard Medical School, one of the study's authors, emphasized that the
• 5:02
  length of time individuals lived near these polluting facilities also played a significant
• 5:08
  role in their risk of developing P.S.P.
• 5:11
  This suggests that prolonged exposure to environmental toxicants might be a crucial
• 5:16
  factor in the development of this disorder.
• 5:19
  Dr.
• 5:20
  Ray Dorsey from Atria Research and Global Health Institute, though not involved in the
• 5:25
  study, pointed out that environmental factors are increasingly being recognized as major
• 5:31
  contributors to neurodegenerative diseases like P.S.P.
• 5:34
  He noted that while genetic factors may play a role, environmental exposures, particularly
• 5:40
  through water or ingestion, could be key to understanding and eventually preventing these
• 5:46
  diseases.
• 5:47
  Progressive supranuclear palsy is characterized by symptoms such as parkinsonism, abnormalities
• 5:54
  in eye movement, and balance issues.
• 5:57
  Unfortunately, there is currently no effective treatment to stop or slow its progression,
• 6:03
  making these findings particularly significant as they open new avenues for prevention and
• 6:08
  research.
• 6:09
  The study's findings underscore the importance of further research to identify the specific
• 6:15
  causes of P.S.P.
• 6:17
  so that preventive measures can be developed.
• 6:20
  As Dr.
• 6:20
  Zhao and his colleagues have shown, understanding the environmental factors at play
• 6:25
  is vital for tackling this debilitating disease.
• 6:30
  Now, let's turn our attention to an innovative wound treatment that is making a significant
• 6:35
  impact on the battlefields in Ukraine.
• 6:38
  Developed in Calgary, Canada, this novel treatment is being delivered by drones to
• 6:43
  assist both soldiers and civilians who have been wounded in the ongoing conflict.
• 6:49
  The treatment, known as NanoSALV Catalytic, was initially funded by Canada's Department of
• 6:54
  National Defence.
• 6:56
  It received approval from Health Canada in 2022 and underwent evaluation by treating unhoused
• 7:03
  populations in encampments.
• 7:05
  Now, it has found a critical use in military settings.
• 7:10
  Megan Leslie, co-founder and chief executive officer of NanoTess, the Calgary-based company
• 7:16
  behind NanoSALV, shared that the journey of this product began with a grant from the
• 7:20
  National Defence back in 2020.
• 7:23
  Fast forward to 2026, and the treatment is now being applied on the front lines in Ukraine.
• 7:30
  NanoSALV is particularly remarkable due to its composition.
• 7:34
  It is a lightweight, non-flammable gel that can be directly applied to wounds.
• 7:39
  The ability to deliver this treatment via drone ensures it reaches those in need quickly, even
• 7:45
  in the most challenging environments.
• 7:48
  The treatment has been available on the Ukrainian front lines since June and has
• 7:53
  already been used to treat 6,000 wounded soldiers and civilians.
• 7:57
  The gel contains nanomaterials that enhance the body's natural healing processes, lower the
• 8:03
  energy required for healing, and combat infection-causing micro-organisms.
• 8:09
  Clinical pharmacist Hailie Uren, who has been working with the Ukrainian Ministry of Health,
• 8:14
  emphasized the critical role of NanoSALV in battlefield medicine.
• 8:19
  She noted that the gel allows wounds to heal without the need for continuous nursing
• 8:23
  intervention, which is vital when resources are stretched thin.
• 8:28
  Hailie Uren shared her experience, stating that after she receives a casualty, she visits the
• 8:35
  next day to check on their wounds.
• 8:37
  The effectiveness of the gel is so well-known that others in the room often request it for
• 8:42
  their injuries as well.
• 8:44
  The significance of this treatment was underscored recently when a wildfire in Canada
• 8:49
  resulted in burn injuries to several soldiers.
• 8:53
  Dr.
• 8:53
  Eric Fung, an Alberta-based surgeon who has experience in Ukraine, highlighted the
• 8:58
  importance of such treatments in mass casualty events where medical systems are already
• 9:03
  overburdened.
• 9:06
  In Saskatchewan, Canada, hundreds of unionized health-care workers recently gathered outside
• 9:12
  the provincial legislature to rally for better contracts.
• 9:16
  These workers, members of the Canadian Union of Public Employees Local 5430, have been without
• 9:23
  a contract since 2023 and are demanding action.
• 9:27
  Their rally highlights a significant issue in the province's health-care system, as these
• 9:32
  workers have not seen a wage increase in over four years.
• 9:37
  Bashir Jalloh, president of CUPE Local 5430, voiced the frustrations of the union members,
• 9:45
  emphasizing that their wages have fallen below the Western Canada average.
• 9:49
  He stressed that historically, Saskatchewan workers were compensated based on this average,
• 9:55
  but now their pay lags significantly behind.
• 9:59
  Last month, an overwhelming 99 percent of the union's membership voted in favor of job
• 10:05
  action, signaling their readiness to escalate the situation if necessary.
• 10:10
  Jalloh noted that while the union is prepared to use this as leverage, it remains a last
• 10:15
  resort, as the members live in the communities they serve and have family members who rely on
• 10:21
  the health-care system.
• 10:23
  Health Minister Jeremy Cockrill addressed the issue, expressing concern over the potential
• 10:28
  disruption in health services.
• 10:31
  He emphasized that the vote for job action is just one step in a complex process and that
• 10:36
  negotiations are ongoing.
• 10:39
  Cockrill highlighted that contract discussions are handled by the Saskatchewan Association of
• 10:43
  Health Organizations, not by him directly.
• 10:47
  In addition to CUPE Local 5430, the Service Employees International Union West, another
• 10:56
  union representing health-care workers, has also been without a contract since 2023.
• 11:01
  Lisa Zunti, the president of SEIU West, called on the health minister to take more
• 11:07
  responsibility, criticizing what she sees as a slow process at the bargaining table.
• 11:13
  Despite the challenges, the health minister remains hopeful that agreements can be reached.
• 11:19
  He pointed out a recent tentative agreement with the Saskatchewan Government Employees'
• 11:23
  Union as a positive step towards resolving these ongoing disputes.
• 11:28
  The province aims to ensure that health-care worker compensation remains competitive with
• 11:33
  the Western Canadian average.
• 11:36
  As the situation unfolds, it's clear that achieving a resolution will require continued
• 11:41
  dialogue and negotiation.
• 11:44
  The outcome of these discussions will be crucial not only for the workers involved but
• 11:49
  also for the communities that depend on their services.
• 11:53
  That brings us to the end of today's episode of Morning Medical with Dr.
• 11:57
  Chow.
• 11:57
  Thank you for joining us as we explored these critical health issues from around the world.
• 12:03
  Stay informed and stay healthy.
