Transcript
- 0:00Welcome to another episode of Morning Medical with Dr.
- 0:02Chow.
- 0:03I'm your host, Dr.
- 0:04Chi-Ming Chow, and today we're diving into the latest news from the world of health and
- 0:09medicine.
- 0:10Our first story takes us to France, where a recent heat wave has had a significant impact
- 0:15on public health.
- 0:19In June, France experienced a historic heat wave that resulted in at least 5,700 more
- 0:26deaths than usual, according to French public health officials.
- 0:30This tragic increase in mortality highlights the severe consequences of extreme weather
- 0:36events on human health, particularly as global temperatures continue to rise.
- 0:41The heat wave, which occurred from June 17 to July 2, was marked by record-breaking
- 0:47temperatures.
- 0:48On June 24 and June 25, France registered its hottest-ever days, with national average
- 0:54temperatures reaching 30 degrees Celsius, or 86 degrees Fahrenheit.
- 1:00In many regions, temperatures soared well above 40 degrees Celsius, or 104 degrees Fahrenheit,
- 1:07even at night.
- 1:09Public Health France reported that the regions affected by the heat wave recorded a total of
- 1:1421,674 deaths from all causes during this period.
- 1:19However, based on statistical modeling using data from previous years, these regions would
- 1:25have expected to see around 15,910 deaths.
- 1:30The difference, estimated at 5,764 excess deaths, underscores the significant impact of
- 1:36such extreme weather conditions.
- 1:39The excess mortality rate during this heat wave was 36 percent higher than what would normally
- 1:44be expected, making it the highest since the catastrophic heat wave of 2003, which caused an
- 1:50estimated 15,000 deaths in France.
- 1:53Almost two-thirds of those who died during this recent heat wave were 75 years or older,
- 1:58highlighting the vulnerability of older populations to extreme heat.
- 2:03The Paris area was particularly hard hit, with nearly 2,000 unexpected deaths recorded.
- 2:09This figure represents around 80 percent more deaths than would have been anticipated without
- 2:14the heat wave.
- 2:16Funeral services in Paris struggled to manage the increased number of bodies, with some
- 2:21mortuaries reaching full capacity and having to turn bodies away.
- 2:26Across Europe, the extreme temperatures led to over 10,000 additional deaths during the height
- 2:32of the heat wave.
- 2:34The heat not only affected the elderly but also posed significant challenges for hospitals,
- 2:40which saw surges in patients suffering from heat-related illnesses.
- 2:44Nearly half of the deaths in France occurred in hospitals, with others occurring at home or in
- 2:49care homes for older individuals.
- 2:52It's important to note that many heat-related deaths may not be directly attributed to the
- 2:58heat itself.
- 3:00For instance, extreme heat can trigger heart attacks, particularly in individuals with
- 3:05pre-existing health conditions, but these may simply be recorded as heart attacks on death
- 3:10certificates.
- 3:12The French health agency plans to update the death toll later this year as more data becomes
- 3:18available.
- 3:19This tragic event serves as a stark reminder of the urgent need to address climate change and
- 3:25prepare for the health impacts of increasingly frequent and intense heat waves.
- 3:32Our next story brings us to Canada, where Canadian Blood Services is facing a pressing
- 3:36challenge.
- 3:38The organization has issued an urgent plea for blood donations as the national blood supply
- 3:44has dropped by nearly 20 percent since the first of June.
- 3:48This decline is even more severe than the typical seasonal slump experienced during the
- 3:55summer months, when many regular donors are away on vacation or busy with other
- 4:00commitments.
- 4:02Ron Vezina, vice-president of donor engagement and corporate reputation at Canadian Blood
- 4:07Services, emphasized the critical need for more donors to come forward to reverse this alarming
- 4:12trend.
- 4:14He stated, "We have seen the blood supply decline by about 20 percent in just a matter of
- 4:19weeks and we need more donors to come forward now to reverse this decline."
- 4:24The agency requires approximately 18,000 blood donation appointments weekly to meet the
- 4:30demands of hospitals across the country.
- 4:33However, since June 1, appointments have consistently fallen short by 1,500 to 2,500 per
- 4:41week.
- 4:43This shortfall has forced Canadian Blood Services to draw on their existing inventory
- 4:48reserves to meet patient needs, which is not a sustainable solution.
- 4:53Blood donations are crucial because blood has a limited shelf life of just 42 days.
- 5:00This means that donations made today are quickly processed and sent to patients in need.
- 5:05Canadian Blood Services has highlighted that several blood types are now at critically low
- 5:10levels, which could impact patient care if the situation does not improve.
- 5:15With the August long weekend approaching, which typically sees an increase in trauma cases and
- 5:20other urgent care needs, it is particularly important to ensure that hospitals have the
- 5:24necessary blood supplies.
- 5:26To address this, Canadian Blood Services has added more weekend appointments at donor
- 5:31centers and whole blood donation appointments at several plasma donor centers.
- 5:37Ron Vezina also urged Canadians to consider donating with a friend, highlighting the
- 5:42communal spirit of giving.
- 5:44He said, "A strong, healthy Canada depends on people showing up for one another.
- 5:50Whether you are a new or returning donor, now is the time to book an appointment.
- 5:55Better yet, bring a friend and experience what you get when you give together."
- 6:01For those interested in donating, appointments can be booked through the Canadian Blood
- 6:05Services website, the GiveBlood app available on Android and Apple devices, or by calling
- 6:11their donation hotline.
- 6:12It is crucial to keep appointments or cancel them in advance if you cannot attend, so that
- 6:17others can fill those slots.
- 6:21Today, we're taking a closer look at a new public health initiative in Canada that aims to
- 6:25curb smoking through the use of graphic warnings on cigarette packages.
- 6:30By August 1, Canadian cigarette packages will feature a new series of graphic images designed
- 6:37to highlight the severe health risks associated with smoking.
- 6:42These images are set to include depictions of mouth cancer, heart disease, and stroke, among
- 6:48other health concerns.
- 6:51The move has been welcomed by experts who believe that such graphic images significantly
- 6:56increase the effectiveness of health warnings.
- 6:59Rob Cunningham, a senior policy analyst at the Canadian Cancer Society, explained that these
- 7:04warnings have been shown to reduce smoking rates.
- 7:08He emphasized the importance of keeping these warnings fresh and impactful by rotating them
- 7:13regularly.
- 7:15The new set of warnings will appear on packages of cigarettes, little cigars, and cigarette
- 7:19tobacco for two years, and on all other tobacco products for three years, before rotating back
- 7:25to previous messages.
- 7:27The new warnings are not just limited to the packaging.
- 7:31Six new messages will also be printed on individual cigarettes, with statements like
- 7:36"Tobacco smoke is toxic" and "Cigarettes harm children." This approach ensures that every
- 7:42time someone smokes, they are reminded of the potential harm.
- 7:47Geoffrey Fong, a professor at the University of Waterloo who studies tobacco use and policies,
- 7:52noted that research consistently shows that graphic images make people more likely to read
- 7:57warning labels, think about the health risks of smoking, and consider quitting.
- 8:02He highlighted that for a smoker who consumes ten cigarettes a day, they would encounter
- 8:07these warnings at least 3,650 times a year, providing constant reminders of the risks.
- 8:15Canada has a history of pioneering graphic warnings on cigarette packages, being the first
- 8:20country to require pictures on its cigarette warnings back in 2001.
- 8:25New images were introduced in 2012 and 2024, and now, this latest update aims to maintain
- 8:32the effectiveness of the warnings by keeping them current and engaging.
- 8:38While the new images have been well-received, there are calls for further measures to
- 8:42discourage smoking, especially among young people.
- 8:46Advocates have pointed to the United Kingdom's recent legislative efforts, such as their
- 8:51generational tobacco ban, which aims to prevent anyone born after 2008 from buying cigarettes
- 8:57and vapes.
- 8:58Although the Canadian government currently has no plans to enact a similar ban, they are
- 9:02monitoring international measures closely.
- 9:06The Lung Health Foundation, a Canadian charity, has emphasized the importance of pairing the
- 9:11graphic warning labels with robust prevention strategies, cessation supports, and public
- 9:18education to effectively reduce smoking and vaping rates across the country.
- 9:24The federal government continues to target a reduction in tobacco use to less than five
- 9:29percent by 2035, as smoking remains a leading cause of preventable death in Canada,
- 9:35responsible for approximately 48,000 deaths annually.
- 9:41The recent FIFA World Cup, hosted across the United States, Canada, and Mexico, was not only
- 9:48a showcase of soccer prowess but also a significant test of public health readiness.
- 9:53The Centers for Disease Control and Prevention played a pivotal role behind the scenes to
- 9:57ensure the safety of millions of fans who traveled from all corners of the globe to
- 10:01witness the event.
- 10:02Acting CDC Director Dr.
- 10:04Jay Bhattacharya highlighted that readiness is not just about responding to emergencies but
- 10:09also about the daily work done to prevent them.
- 10:12This World Cup was a testament to the CDC's partnerships and preparedness, crucial in
- 10:17protecting public health.
- 10:19With 48 teams competing in 16 cities across three countries, the event drew an estimated
- 10:256.5 million fans.
- 10:27This massive convergence of people brought not only excitement but also potential health
- 10:33risks, particularly with concurrent international disease activity such as the
- 10:38Ebola and Hantavirus outbreaks.
- 10:41The CDC was alert to these risks, monitoring for signs of potential outbreaks by examining
- 10:47wastewater, hospital visit trends, and even social media activity.
- 10:53One of the CDC's key tools during the tournament was a data dashboard providing
- 10:58real-time disease trend information to health departments in host cities.
- 11:02This was complemented by round-the-clock health operations at U.S.
- 11:06ports of entry, conducted in coordination with U.S.
- 11:09Customs and Border Protection, to monitor international passengers.
- 11:14The agency's efforts extended to deploying experts to enhance disease surveillance,
- 11:19improve laboratory capacity, and develop preparedness plans in host cities.
- 11:25Collaboration was essential, involving multiple CDC divisions, the Department of Health and
- 11:31Human Services, the Administration for Strategic Preparedness and Response, and the
- 11:35White House FIFA World Cup Task Force.
- 11:40As part of its ongoing mission, the CDC released guidance earlier in the year to help
- 11:45health officials prepare for a wide range of potential threats, including biological,
- 11:51chemical, radiologic, nuclear, environmental, and mass casualty incidents.
- 11:58This guidance encouraged jurisdictions to adopt a risk-based approach, recognizing that the
- 12:04movement of fans between venues could connect communities far beyond the host cities.
- 12:10Although the World Cup has concluded, the CDC's work continues.
- 12:15The agency's preparedness, surveillance, and partnerships are integral to its readiness and
- 12:21response mission, which extends well beyond the close of this international event.
- 12:27The lessons learned and strategies developed during the World Cup will continue to inform
- 12:31public health efforts in the future.
- 12:35Our final story today focuses on the West Nile virus, which is currently making its presence
- 12:41known across Ontario.
- 12:43Health officials have detected positive mosquito pools carrying the virus in multiple
- 12:48communities, including Toronto, Windsor-Essex, Belleville, York Region, and Halton Region.
- 12:56These findings serve as an early indication that the virus is circulating locally, although
- 13:01no human cases have been reported in these areas so far.
- 13:06Toronto Public Health confirmed that one batch of mosquitoes tested positive for West Nile
- 13:10virus this season.
- 13:12Similarly, Windsor-Essex and the Belleville area have each identified a positive mosquito
- 13:17pool.
- 13:19In York Region, two positive mosquito traps and two positive mosquito pools were reported, both
- 13:25in Markham.
- 13:26Halton Region also noted two positive mosquito pools during the week of July 13 to 19.
- 13:33Across Canada, a total of fourteen dead wild birds have tested positive for the virus, with
- 13:39thirteen found in Ontario and one in Manitoba.
- 13:43Health officials caution against handling dead birds or animals with bare hands as they may
- 13:48carry the West Nile virus or other pathogens.
- 13:52It is recommended to bury them using a shovel and gloves at a depth of at least fifty
- 13:57centimeters, or about one and a half feet, in a location that will not be disturbed.
- 14:04While the presence of West Nile virus at this time of year is not unusual, residents are
- 14:09urged to take precautions against mosquito bites.
- 14:12West Nile virus is spread to humans through the bites of infected mosquitoes, which pick up the
- 14:18virus after feeding on birds, the natural hosts.
- 14:22Fortunately, it is not spread through casual contact between people.
- 14:27Most people infected with West Nile virus do not develop symptoms.
- 14:32However, some may experience mild symptoms like headache, fever, and chills for a few days
- 14:37before recovering.
- 14:39In rare cases, the infection can lead to more severe health issues such as neuromuscular
- 14:44disorders and other nerve-related problems.
- 14:48Older adults and individuals with weakened immune systems are at a heightened risk of
- 14:52severe illness.
- 14:54Dr.
- 14:55Isaac Bogoch, an infectious diseases specialist and professor at the University of Toronto,
- 15:00advises that the current detections should not deter people from enjoying outdoor activities.
- 15:06He suggests practical measures to stay protected, such as wearing long clothing,
- 15:10applying mosquito repellent containing DEET or icaridin, and removing standing water around
- 15:16homes where mosquitoes breed.
- 15:18Additionally, extra precautions should be taken at dawn and dusk when mosquitoes are most
- 15:23active.
- 15:24As we wrap up today's episode, it's clear that whether it's the impact of climate change, the
- 15:29need for blood donations, new public health initiatives, or the vigilance required during
- 15:34large international events, health is a dynamic field that affects us all.
