  Chow, your daily update on the latest medical and health news from around the world, powered
• 0:07
  by artificial intelligence.
• 0:09
  I'm Dr.
• 0:09
  Chi-Ming Chow, a cardiologist, family physician, and general internist based in
• 0:14
  Toronto, Ontario, Canada.
• 0:16
  I'm also a Professor of Medicine at the University of Toronto, and I'll be your host
• 0:20
  for today's episode.
• 0:21
  Let's dive into today's top stories.
• 0:27
  Our first story comes from the province of Manitoba, where the nurses' union is sounding
• 0:31
  the alarm over an 'absolutely chaotic' situation at the Health Sciences Centre's
• 0:37
  emergency department.
• 0:38
  According to the Manitoba Nurses Union, the emergency department at the province's largest
• 0:43
  hospital has been operating at double capacity for more than a week.
• 0:47
  At one point, the department was dealing with up to 120 active patients, far exceeding its
• 0:53
  usual capacity.
• 0:55
  The union has expressed grave concerns about the safety of patients and the working
• 0:59
  conditions of nurses, stating that the current situation is unsustainable.
• 1:04
  According to union president Darlene Jackson, some adult patients had to be diverted to the
• 1:09
  children's emergency department due to the overwhelming number of cases.
• 1:13
  She described the scene as 'absolutely chaotic,' with patients being treated in
• 1:18
  hallways and a severe shortage of resuscitation spaces.
• 1:23
  One patient, Ronald Harper, recounted his experience of arriving at the hospital at 9
• 1:27
  a.m.
• 1:27
  and not receiving a room until 3 p.m., highlighting the long wait times faced by those
• 1:33
  in need of urgent care.
• 1:35
  Shared Health, the organization responsible for providing health services in Manitoba, declared
• 1:41
  a surge in the emergency department on Tuesday after all high-acuity beds were filled.
• 1:47
  In an effort to manage the overflow, some young patients were seen at the children's emergency
• 1:52
  department.
• 1:54
  In response to the situation, Manitoba Premier Wab Kinew stated that his government is working
• 2:01
  hard to improve emergency services.
• 2:04
  He noted that the median wait time for priority patients at the Health Sciences Centre was
• 2:11
  about two hours and 20 minutes, but acknowledged that more work is needed to ensure
• 2:15
  everyone receives timely care.
• 2:18
  However, the union and other critics argue that these figures do not accurately reflect the
• 2:22
  experiences of the majority of patients, who often face much longer waits.
• 2:28
  Kathleen Cook, a health critic for the Progressive Conservatives, called the situation
• 2:33
  a 'crisis' and emphasized the need for a credible staffing plan.
• 2:37
  She expressed skepticism about the government's current approach to resolving the staffing
• 2:42
  shortages that heavily contribute to the problem.
• 2:46
  Darlene Jackson echoed these concerns, urging the government to prioritize staff retention
• 2:51
  and address the heavy workloads that nurses are facing.
• 2:57
  Our next story highlights a critical situation in the United States, where federal food
• 3:01
  benefits and preschool aid are on the brink of running out due to the ongoing government
• 3:07
  shutdown.
• 3:09
  If Congress doesn't reach an agreement by this Saturday, millions of Americans could be
• 3:14
  without crucial support.
• 3:17
  This shutdown threatens to create significant gaps in the country's safety net, especially
• 3:22
  for programs like the Supplemental Nutrition Assistance Program, or SNAP, which is vital for
• 3:28
  about one in eight Americans who rely on it to buy groceries.
• 3:32
  SNAP benefits are set to run dry starting this Saturday, and uncertainty looms over whether
• 3:40
  remaining balances on beneficiaries' debit cards will be usable come November.
• 3:46
  With the average monthly benefit being one hundred and eighty-seven dollars per person,
• 3:50
  many families who qualify for SNAP are already living at or below the poverty line.
• 3:57
  Some states, like Arkansas, have advised beneficiaries to use their remaining funds on
• 4:03
  shelf-stable foods this month, while others like Missouri and Pennsylvania expect the
• 4:09
  balances to remain accessible and are encouraging beneficiaries to save for November
• 4:14
  if possible.
• 4:16
  The Trump administration has rejected the use of five billion dollars in contingency funds to
• 4:22
  continue providing federal cash for food, despite calls from Democratic lawmakers and
• 4:28
  advocacy groups to do so.
• 4:30
  This decision is in contrast to a recent report from the United States Department of
• 4:36
  Agriculture, which indicated that such a contingency fund could be used to cover SNAP
• 4:42
  benefits if government funding lapses.
• 4:46
  However, the administration argues that these reserves are intended for disaster-related
• 4:51
  expenses.
• 4:53
  In response to the potential shortfall, states like Louisiana, Vermont, and Virginia have
• 4:59
  pledged to backfill food aid for recipients, although specific details are still being
• 5:03
  worked out.
• 5:05
  In Louisiana, the House has unanimously voted to urge the state's health department to use
• 5:10
  one hundred and fifty million dollars from its budget to prevent an interruption in SNAP
• 5:16
  benefits for nearly eight hundred thousand residents.
• 5:20
  Meanwhile, states like New Hampshire, Minnesota, California, New Mexico, Connecticut,
• 5:26
  and New York are ramping up funding for food banks and pantries to help fill the void.
• 5:34
  The shutdown also threatens early childhood education, with more than one hundred and
• 5:38
  thirty Head Start preschool programs at risk of not receiving their annual federal grants by
• 5:44
  November first.
• 5:45
  This could impact over sixty-five thousand seats at these programs nationwide, forcing
• 5:51
  many centers to rely on dwindling reserves or local government assistance to stay open.
• 5:57
  When these centers close, it can disrupt the lives of families who depend on them for
• 6:03
  education and child care, potentially causing parents to miss work or school.
• 6:08
  Additionally, the Special Supplemental Nutrition Program for Women, Infants, and
• 6:12
  Children, known as WIC, is also facing funding issues.
• 6:15
  Despite receiving a temporary infusion of funds to keep the program operational through
• 6:19
  October, this money is expected to run out early next month.
• 6:23
  This program supports over six million low-income mothers, young children, and
• 6:28
  expectant parents with essential nutrition assistance.
• 6:31
  States have warned that they could run out of WIC funds as early as November eighth, leaving
• 6:36
  many vulnerable families without support.
• 6:40
  Our next story delves into promising research on a plant-based estrogen known as estetrol,
• 6:47
  which has shown potential in reducing menopause symptoms in women.
• 6:51
  This study was presented at the Menopause Society annual meeting and involved over 1,200
• 6:57
  postmenopausal women.
• 6:59
  The research focused on estetrol, one of four natural estrogens, which has been found to
• 7:04
  significantly diminish the severity and frequency of vasomotor symptoms, such as hot
• 7:10
  flashes, in these women.
• 7:13
  The research consisted of two phase three trials, named E4COMFORT I and E4COMFORT II,
• 7:19
  which analyzed the effects of once-daily oral doses of estetrol at 15 milligrams and 20
• 7:25
  milligrams.
• 7:26
  Both doses led to greater reductions in menopause symptoms compared to a placebo, with
• 7:32
  the 20-milligram dose achieving the most substantial and earliest improvements.
• 7:37
  The study highlighted that improvements were not only observed early on but were also
• 7:42
  sustained throughout the study duration.
• 7:45
  An interesting aspect of estetrol is that although it's a natural estrogen produced in
• 7:50
  the human fetal liver, for clinical purposes, it's manufactured from plant sources.
• 7:55
  This makes it a unique option among estrogens.
• 7:58
  Also noteworthy is that estetrol has minimal impact on liver proteins, a common concern with
• 8:04
  other oral estrogens.
• 8:06
  It bypasses the cytochrome P450 enzyme system, reducing the potential for drug interactions,
• 8:13
  which is a significant advantage for patients who may be on multiple medications.
• 8:18
  Dr.
• 8:19
  Ekta Kapoor from the Mayo Clinic, who presented the findings, emphasized that estetrol
• 8:26
  activates only the nuclear estrogen receptor alpha in various cell types, including breast
• 8:31
  cells, without encouraging breast cell proliferation, which is a promising safety
• 8:36
  feature.
• 8:37
  In terms of tolerability, estetrol was well received by women who had undergone a
• 8:42
  hysterectomy, with few adverse events reported, such as vaginal bleeding and breast tenderness,
• 8:48
  none of which led to discontinuation of the treatment.
• 8:52
  The study participants ranged in age from 40 to 65 and included women from diverse geographical
• 8:58
  regions, such as Europe, Russia, Latin America, and North America, with a range of body mass
• 9:04
  indexes.
• 9:06
  This diversity adds to the robustness of the findings.
• 9:11
  Dr.
• 9:12
  Kapoor concluded that estetrol represents a potential alternative for hormone treatment in
• 9:18
  managing moderate-to-severe menopause symptoms, offering benefits like minimal liver impact and
• 9:24
  reduced drug interaction potential.
• 9:28
  Let's turn to an intriguing study that explores the impact of nighttime light exposure on heart
• 9:34
  health.
• 9:35
  New research suggests that sleeping in total darkness may not only support restful sleep but
• 9:41
  could also lower the risk of cardiovascular disease, which is the leading cause of death
• 9:46
  worldwide.
• 9:47
  This study, published in the journal JAMA Network Open, found that people who slept in
• 9:52
  the brightest conditions had a significantly higher risk of developing heart failure,
• 9:57
  coronary artery disease, and stroke.
• 10:01
  The study tracked participants' exposure to light intensity using wrist wearables between
• 10:07
  12:30 a.m.
• 10:08
  and 6 a.m.
• 10:09
  Dr.
• 10:10
  Daniel Windred, a co-first author of the study from Flinders University in Australia, noted
• 10:15
  that while the study measured light intensity, it did not identify specific sources of light
• 10:20
  exposure.
• 10:22
  However, understanding these sources could help make more informed recommendations beyond
• 10:27
  simply avoiding bright light at night.
• 10:30
  Light exposure at night can block the brain's production of melatonin, the hormone that
• 10:35
  induces sleep.
• 10:37
  Reducing nighttime light exposure can begin with changes to your evening routine.
• 10:43
  Experts suggest limiting screen time and turning off unnecessary household lights within
• 10:48
  four hours of bedtime.
• 10:50
  If turning lights off completely isn't possible, using dim or warm lighting instead of
• 10:56
  bright overhead lights could be beneficial.
• 10:59
  In addition, avoiding bright alarm clocks and sleeping near windows can help.
• 11:04
  Light-blocking window shades, blackout curtains, and sleep masks can also be useful in
• 11:10
  minimizing light exposure while sleeping.
• 11:14
  The study authors described this research as "the largest known study" examining long-term
• 11:19
  associations between individual light exposure and cardiovascular disease risk, analyzing 13
• 11:26
  million hours of light data for nearly 89,000 people.
• 11:31
  The research builds on previous studies that have shown similar associations and established
• 11:36
  that disruption to circadian rhythms is a known risk factor for poor cardiovascular health.
• 11:42
  Circadian rhythms are 24-hour cycles present in virtually every cell and tissue in our body,
• 11:48
  including our cardiovascular system.
• 11:51
  This internal clock helps regulate sleep and wake cycles by using light as a signal to be
• 11:56
  awake and darkness as a cue for sleep.
• 12:00
  The study participants, who were on average 62 years old, were part of the United Kingdom
• 12:05
  Biobank study, which has tracked the health outcomes of over 500,000 individuals since
• 12:10
  2006.
• 12:12
  Participants wore light trackers for a week during their normal lives, and their health
• 12:16
  outcomes were monitored for an average of nine years.
• 12:20
  Those with pre-existing cardiovascular issues were excluded from the study.
• 12:25
  The findings revealed that those exposed to the brightest light had a 47% greater risk of
• 12:30
  having a heart attack and a 32% higher risk of developing atrial fibrillation, an irregular
• 12:36
  heart rhythm.
• 12:38
  While the study does not prove causation, it does highlight a significant link between
• 12:43
  nighttime light exposure and cardiovascular risk.
• 12:47
  The study controlled for factors such as physical activity, smoking, alcohol intake,
• 12:52
  diet, and shift work, which could influence cardiovascular health.
• 12:58
  While the study provides compelling evidence, it also acknowledges limitations, such as a
• 13:03
  lack of participant diversity and details on sleep quality.
• 13:07
  More research is needed to understand how changes to lighting could reduce cardiovascular
• 13:12
  disease risk.
• 13:13
  Nevertheless, this study underscores the importance of managing nighttime light exposure
• 13:18
  as a potential factor in maintaining heart health.
• 13:24
  Our final story today shines a light on the benefits of long walks for heart health and
• 13:28
  longevity, as detailed in a new study published in the journal Annals of Internal Medicine.
• 13:34
  This research underscores that walking for extended periods, defined as longer than ten
• 13:38
  minutes, can significantly reduce the risks of cardiovascular disease and premature death,
• 13:44
  especially for those who are less active.
• 13:47
  The study, led by Dr.
• 13:49
  Borja del Pozo Cruz, highlights that it's not just the total number of steps taken each day
• 13:54
  that matters, but also how those steps are accumulated.
• 13:59
  This finding adds a new layer to the well-known '10,000 steps a day' guideline.
• 14:04
  Even if you do not reach that number, taking a few longer walks rather than many short,
• 14:09
  scattered steps can make a tangible difference for heart health and longevity.
• 14:15
  Alarmingly, nearly thirty-one percent of the world's adult population is physically
• 14:20
  inactive, failing to meet the global recommendation of at least one hundred fifty
• 14:25
  minutes of exercise per week.
• 14:28
  Sedentary lifestyles are linked to higher risks of insomnia, mortality, and cardiovascular
• 14:35
  disease.
• 14:36
  Dr.
• 14:37
  del Pozo Cruz emphasized that everyone can benefit from walking, but these findings are
• 14:42
  particularly relevant for those who take fewer than about eight thousand steps a day.
• 14:48
  Building the capacity for longer walks can help improve cardiovascular health and heart
• 14:53
  strength.
• 14:54
  Dr.
• 14:55
  Andrew Freeman, director of cardiovascular prevention and wellness at National Jewish
• 14:59
  Health in Denver, likens this to building muscle strength.
• 15:03
  Just as you wouldn't lift a heavy weight without building up to it, extending your
• 15:07
  walking duration is something to work towards gradually.
• 15:11
  Longer walks can enhance blood circulation, lower blood pressure, and support glucose
• 15:16
  control, all of which are vital for heart health.
• 15:20
  They also increase the volume of heart stimulation needed to fully engage your
• 15:24
  muscles.
• 15:25
  However, much like any exercise, it's important to build up to longer periods gradually.
• 15:32
  The study suggests that instead of focusing solely on step counts, individuals should
• 15:37
  consider the duration and consistency of walking bouts.
• 15:40
  Incorporating short sessions of continuous walking during the day can be a powerful factor
• 15:45
  for improving heart health.
• 15:47
  Simple changes, like parking farther from your destination or engaging in 'cozy cardio,' can
• 15:54
  increase your walking duration.
• 15:56
  Dr.
• 15:58
  Freeman recommends aiming for roughly thirty minutes a day of breathless physical activity,
• 16:03
  which is an intense level for most people.
• 16:06
  Breathless activity means walking briskly enough that you can talk, but not sing.
• 16:12
  Other exercises beneficial for heart health include wall sits, planks, and aerobic
• 16:16
  activities like biking.
• 16:19
  The findings were based on an observational study analyzing data from over thirty-three
• 16:24
  thousand adults in the United Kingdom Biobank.
• 16:27
  Participants were relatively inactive, defined as walking less than eight thousand steps per
• 16:33
  day.
• 16:33
  The study used accelerometers to track movement, though it did not monitor changes in
• 16:38
  walking habits over time.
• 16:41
  In conclusion, this study highlights the importance of incorporating longer walks into
• 16:45
  your routine for better heart health and longevity.
• 16:49
  It serves as a reminder that simple, consistent changes to our daily activities can have
• 16:54
  profound effects on our overall well-being.
• 16:57
