  Hello and welcome to Morning Medical with Dr.
• 0:02
  Chow, your daily update on the latest medical and health news from around the world.
• 0:07
  I'm Dr.
• 0:08
  Chi-Ming Chow, a cardiologist based in Toronto, Canada, and your host for today's episode.
• 0:14
  We aim to bring you the most relevant and groundbreaking stories in the medical field,
• 0:18
  and today, we have a fascinating topic to discuss: dogs successfully detecting
• 0:23
  Parkinson's disease.
• 0:28
  Imagine a future where your furry friend could help diagnose a serious neurological condition.
• 0:35
  This concept is becoming a reality as research has shown that trained dogs can detect
• 0:41
  Parkinson's disease through sebum swabs.
• 0:45
  In a recent study conducted by researchers from the University of Bristol in England, two dogs,
• 0:50
  Bumper and Peanut, demonstrated the ability to identify Parkinson's disease with up to 80
• 0:56
  percent sensitivity and an impressive 98 percent specificity.
• 1:01
  Sebum, a natural oil produced by our skin, can be collected easily using gauze swabs on the
• 1:07
  face or upper back.
• 1:09
  Unlike other biofluids such as blood, sebum does not need to be stored under stringent cold
• 1:14
  conditions, making it a cost-effective sample medium.
• 1:17
  The study involved training the dogs for 38 to 53 weeks, during which they learned to
• 1:24
  distinguish between sebum swabs from people with and without Parkinson's disease.
• 1:30
  The results were encouraging, as the dogs correctly identified a significant portion of
• 1:35
  the Parkinson's samples while ignoring a majority of the control samples.
• 1:40
  This research is not limited to canine detection.
• 1:43
  Another study from the University of Manchester explored the chemical composition of sebum
• 1:47
  using mass spectrometry.
• 1:49
  This technique allowed researchers to differentiate between individuals with isolated
• 1:53
  REM sleep behavior disorder, an early sign of Parkinson's, and those with established
• 1:58
  Parkinson's disease, as well as healthy controls.
• 2:02
  The mass spectrometry analysis revealed 55 significant features in sebum that varied among
• 2:07
  these groups.
• 2:09
  These studies were inspired by Joy Milne, a nurse with a heightened sense of smell who
• 2:15
  noticed distinct odors associated with different diseases, including Parkinson's.
• 2:20
  Her observations led researchers to investigate the molecular basis of these odors.
• 2:26
  In this pursuit, they have made strides toward developing a non-invasive, reliable test that
• 2:32
  could potentially allow for early detection of Parkinson's disease, tracking its progression,
• 2:37
  and ultimately improving patient outcomes.
• 2:41
  The implications of these findings are profound.
• 2:45
  Currently, there is no early test for Parkinson's disease, but these studies bring us
• 2:50
  closer to a future where a simple skin swab could identify individuals at risk before
• 2:55
  symptoms arise.
• 2:57
  The research was funded by the Michael J.
• 2:59
  Fox Foundation and Parkinson's U.K., and the researchers involved have declared no competing
• 3:05
  interests.
• 3:07
  With these promising developments, we hope that the day is not far when early intervention can
• 3:12
  significantly alter the course of Parkinson's disease.
• 3:15
  As always, we will continue to keep you updated on any advancements in this field.
• 3:19
  Thank you for tuning in to Morning Medical with Dr.
• 3:22
  Chow.
• 3:23
  Stay with us as we delve into our next segment.
• 3:28
  In our next segment, we're turning our attention to a serious global health issue that
• 3:33
  has been highlighted by the United Nations.
• 3:37
  Recent reports have revealed that more than fourteen million children worldwide did not
• 3:42
  receive a single vaccine in the year two thousand twenty-four.
• 3:46
  This alarming statistic underscores the challenges we face in ensuring global vaccine
• 3:52
  coverage, particularly in light of recent geopolitical developments.
• 3:57
  According to the annual estimate of global vaccine coverage released by the World Health
• 4:02
  Organization and the United Nations International Children's Emergency Fund, about
• 4:06
  eighty-nine percent of children under one year old received their first dose of the
• 4:10
  diphtheria, tetanus, and whooping cough vaccine in two thousand twenty-four, which is
• 4:16
  consistent with the previous year.
• 4:18
  However, only eighty-five percent completed the three-dose series, indicating a slight
• 4:23
  improvement from eighty-four percent in two thousand twenty-three.
• 4:28
  The report highlights that nine countries accounted for over half of the unvaccinated
• 4:32
  children.
• 4:33
  These countries include Nigeria, India, Sudan, Congo, Ethiopia, Indonesia, Yemen, Afghanistan,
• 4:42
  and Angola.
• 4:44
  The situation is particularly concerning in Sudan, which reported the lowest coverage
• 4:49
  against these diseases.
• 4:51
  The collapse of international aid is a significant hurdle in addressing this issue.
• 4:57
  Earlier this year, the United States withdrew from the World Health Organization and froze
• 5:02
  nearly all humanitarian aid.
• 5:06
  This decision, coupled with the withdrawal of financial commitments to the vaccines alliance
• 5:11
  known as Gavi, has exacerbated the situation.
• 5:15
  Health Secretary Robert F.
• 5:17
  Kennedy Jr., a known vaccine skeptic, has raised doubts about the safety of vaccines,
• 5:24
  despite their proven efficacy in preventing between three and a half to five million deaths
• 5:28
  annually.
• 5:30
  The disparity in vaccine access remains a critical issue, with conflict and humanitarian
• 5:36
  crises quickly unraveling progress.
• 5:39
  The World Health Organization's Director-General, Tedros Adhanom Ghebreyesus,
• 5:44
  has expressed deep concern over the potential unwinding of decades of progress due to drastic
• 5:51
  cuts in aid and the spread of misinformation about vaccines.
• 5:55
  On a somewhat positive note, global coverage against measles has seen a slight increase,
• 6:01
  with seventy-six percent of children receiving both doses of the vaccine.
• 6:06
  However, experts stress that a ninety-five percent coverage rate is necessary to prevent
• 6:13
  outbreaks of this highly contagious disease.
• 6:16
  The United States is currently experiencing its worst measles outbreak in over thirty years,
• 6:22
  and Europe has seen a significant surge in cases as well.
• 6:26
  This situation highlights the critical importance of vaccination in preventing disease
• 6:31
  outbreaks.
• 6:32
  As Helen Bradford, a professor of children's health at University College London, pointed
• 6:37
  out, "The only way to stop measles spreading is with vaccination.
• 6:42
  It is never too late to be vaccinated—even as an adult."
• 6:45
  As we continue to navigate these challenges, it's crucial to ensure that accurate
• 6:50
  information about the safety and efficacy of vaccines is widely disseminated to combat
• 6:55
  misinformation.
• 6:56
  The health and well-being of millions of children depend on it.
