Transcript
- 0:00Welcome back to another episode of Morning Medical with Doctor Chi-Ming Chow, your daily
- 0:04update on the latest medical and health news from around the world.
- 0:07I'm Doctor Chi-Ming Chow, your host, a cardiologist and professor of medicine at the
- 0:11University of Toronto.
- 0:13Today, we're diving into some new research on the respiratory syncytial virus, or RSV, and
- 0:19how it affects older adults.
- 0:21A new study suggests that some older adults might benefit from a booster shot of the RSV
- 0:28vaccine.
- 0:30While current guidelines recommend a single dose for older adults, there's limited
- 0:34long-term data on how long that protection actually lasts.
- 0:38This study, which focused on United States veterans, found that the effectiveness of the
- 0:43vaccine slid from over 80 percent in the month following vaccination to about 60 percent after
- 0:5018 months.
- 0:51This decrease was even more pronounced among the immunocompromised, where effectiveness fell
- 0:56from 75 percent to 40 percent.
- 1:00The researchers, led by Doctor Kristina Bajema from the VA Portland Health Care System,
- 1:05conducted a large observational study on veterans aged 60 and up.
- 1:11They found that the vaccine's real-world effectiveness against documented RSV infection
- 1:17dropped from 82.5 percent in the first month to 59.4 percent by month eighteen.
- 1:23Among immunocompromised individuals, the effectiveness fell sharply from 75.2 percent to
- 1:2939.7 percent over the same period.
- 1:33The findings suggest that while the vaccine offers strong initial protection, there is
- 1:38significant waning over time, especially for those with compromised immune systems.
- 1:43The study's authors suggest that the potential benefits and risks of a second vaccine dose in
- 1:48certain groups should be examined.
- 1:49They believe that boosters could be beneficial for high-risk groups, such as the
- 1:53immunocompromised.
- 1:56The study also showed stronger protection against serious RSV-related outcomes like
- 2:01hospitalizations and intensive care unit admissions.
- 2:05For instance, vaccine effectiveness against hospitalization was 88.9 percent at one month
- 2:11and 57.3 percent by month eighteen.
- 2:14Similarly, effectiveness against intensive care unit admissions was 92.5 percent initially,
- 2:21dropping to 71.9 percent over time.
- 2:25In an accompanying editorial, Doctor Anna Hung from Duke University and Doctor Lona Mody from
- 2:31the University of Michigan highlighted the importance of this study.
- 2:35They emphasized that while boosters may be needed, the current focus should be on
- 2:40encouraging vaccination among older adults, especially those 75 years and older and those
- 2:46with underlying health issues.
- 2:48Despite the recommendations, less than half of adults 75 and older and just 38 percent of
- 2:55high-risk adults aged 60 to 74 have reported receiving an RSV vaccine, according to recent
- 3:02CDC data.
- 3:04The study emulated a randomized trial design, comparing vaccinated and unvaccinated veterans,
- 3:10and found that the adjuvanted RSV prefusion F protein-based vaccine was more effective over
- 3:1718 months compared to the bivalent RSV prefusion F protein vaccine.
- 3:24It's important to note some limitations of the study, such as the potential for incomplete RSV
- 3:29infection records and the predominantly white male veteran population, which may impact the
- 3:34generalizability of the findings.
- 3:37However, the study provides valuable insights that could help shape future vaccination
- 3:41guidance.
- 3:44The Canadian Veterinary Medical Association is raising alarms over two critical issues facing
- 3:49the veterinary sector in Canada: medicine shortages and staff burnout.
- 3:54These challenges are not only affecting veterinarians but also impacting pet owners who
- 4:00are struggling with rising costs of pet medications.
- 4:03In Saskatoon, Saskatchewan, Inoka Gamage, a seasoned veterinarian with over two decades of
- 4:10experience, highlighted the intense pressures faced by veterinary professionals.
- 4:16At her practice, Fairlight Veterinary Services, the workload is relentless, with long hours and
- 4:23emergency cases that cannot be turned away, leading to widespread burnout among staff.
- 4:29The Canadian Veterinary Medical Association's president, Tracy Fisher, spoke at a news
- 4:34conference in Ottawa, emphasizing that supply shortages are driving up the prices of
- 4:40essential pet medications, such as antibiotics, sedatives, and vaccines.
- 4:46Fisher called on the federal government to regulate these costs and address the shortages.
- 4:52According to Fisher, part of the problem stems from changes to Health Canada's registration
- 4:57process, which have made it more challenging to bring medicines into the country.
- 5:01The association has proposed several measures to alleviate the strain on veterinarians,
- 5:07including reducing bureaucratic hurdles and costs, establishing a national testing center
- 5:12for faster accreditation of foreign-trained veterinarians, and increasing mental health
- 5:16support for veterinary teams.
- 5:19Sabrina Fagnou, a veterinary technician in Saskatoon, voiced concerns about the impact of
- 5:24these issues on client relations.
- 5:27She noted that pet owners often express frustration at the clinic staff for the high
- 5:32prices and limited availability of medications.
- 5:36Fagnou pointed out that these frustrations are exacerbated when alternative medications are
- 5:41significantly more expensive due to shortages.
- 5:46The financial strain is further compounded by provincial taxes on veterinary medicines in
- 5:50Saskatchewan, which increase costs once the medicines are brought in from Alberta.
- 5:56Inoka Gamage expressed her concerns about these tax hikes, suggesting that provincial relief
- 6:01could help reduce some of the financial pressure on veterinary practices.
- 6:06Additionally, Canada's Competition Bureau has indicated that pet owners should have more
- 6:12options regarding where they can fill prescriptions, such as at various pharmacies.
- 6:17However, the availability of these drugs in Canada remains a pressing issue before such
- 6:24changes can be implemented.
- 6:28Let's discuss the potential impact of the sugar tax on your favorite drinks.
- 6:33With rising concerns about public health and the cost of living, governments around the
- 6:37world are considering measures like the sugar tax to curb the consumption of sugary
- 6:42beverages.
- 6:43The idea is to disincentivize the purchase of these drinks by making them more expensive,
- 6:48thereby encouraging healthier choices.
- 6:52In countries where a sugar tax has already been implemented, we've seen a mixed response from
- 6:56both consumers and manufacturers.
- 6:59Some beverage companies have chosen to reformulate their products to contain less
- 7:03sugar, thus avoiding the tax.
- 7:06Others have opted to maintain their original recipes, passing the increased costs onto
- 7:11consumers.
- 7:13The economic impact of the sugar tax can vary significantly depending on several factors,
- 7:19such as the tax rate, the types of drinks included, and consumer behavior.
- 7:24For instance, in the United Kingdom, the introduction of a sugar tax led to a
- 7:29significant reduction in sugar content in many soft drinks.
- 7:33However, the cost of these beverages for consumers did not necessarily decrease, as
- 7:39companies adjusted their pricing strategies.
- 7:42If you're wondering whether your favorite drink might cost more in the future, it largely
- 7:47depends on how your local government chooses to implement or adjust such taxes.
- 7:52It's also worth considering how beverage companies respond, whether by changing their
- 7:57product formulations or pricing structures.
- 8:00Ultimately, the goal of these measures is to promote better health outcomes by reducing
- 8:05sugar consumption, which is linked to various health issues like obesity, diabetes, and heart
- 8:10disease.
- 8:11While the financial implications are important, the broader public health benefits could be
- 8:16significant, potentially leading to long-term savings in healthcare costs.
- 8:22With Thanksgiving just around the corner, many of us are thinking about how to make our
- 8:26holiday meals not only delicious but also healthy.
- 8:31One approach to consider is making your meal "blue zone"-friendly.
- 8:36For those unfamiliar with the term, "blue zones" are regions of the world where people
- 8:41live significantly longer and healthier lives.
- 8:45These areas include places like Okinawa, Japan and Sardinia, Italy, where plant-based diets
- 8:53are the norm.
- 8:55National Geographic fellow and author Dan Buettner has been studying these blue zones for
- 8:59years, and he offers some practical tips on how to incorporate these healthy eating habits into
- 9:04your Thanksgiving feast.
- 9:06First, Buettner suggests inviting the "three sisters" to your meal.
- 9:11In the context of Thanksgiving, this refers to beans, corn, and squash, which are traditional
- 9:17Native American staples.
- 9:19These foods are not only nutrient-rich but are also found in the diets of people in blue zones
- 9:24like Costa Rica's Nicoya region and Greece's Icaria island.
- 9:30Next, you can spotlight vegetables in your side dishes.
- 9:33Blue zone diets are rich in leafy greens such as mustard greens, collards, and wild arugula.
- 9:40Adding a simple herb-heavy salad or roasted seasonal vegetables can lighten up the
- 9:45traditionally heavy Thanksgiving meal.
- 9:48For example, Buettner shares a recipe for honey-roasted carrots, which combines carrots
- 9:53with olive oil, lemon juice, and honey, roasted with spices for a delicious and healthy side
- 9:59dish.
- 10:01Moving on, Buettner recommends calling in the whole grains.
- 10:04Instead of using refined grains, try incorporating whole-grain alternatives like
- 10:08sourdough, barley, or wild rice.
- 10:11These options help keep blood sugar levels stable and keep you fuller with fewer calories.
- 10:17Even classic dishes like mashed potatoes can be updated with healthier ingredients, such as
- 10:21using olive oil and fresh chives instead of butter and cream.
- 10:26When it comes to dessert, Buettner advises rethinking the sweets.
- 10:30Rather than indulging in a variety of pies, consider offering baked apples or roasted
- 10:36squash.
- 10:37These naturally sweet options provide a satisfying end to the meal without the excess
- 10:42sugar.
- 10:43In blue zones, people often enjoy a single, simple sweet after meals, which aligns with
- 10:48healthier eating habits.
- 10:50Finally, Buettner emphasizes the importance of strengthening ties with family and friends
- 10:55during the holiday.
- 10:56A "blue zone" Thanksgiving goes beyond just what's on the plate.
- 11:01It's about the connections and activities that surround the meal.
- 11:05Consider playing games, sharing gratitude stories, or including elders in the cooking
- 11:10process.
- 11:11After the meal, take a walk together instead of heading straight for the couch.
- 11:16It's these social interactions and physical activities that contribute to longevity and
- 11:20well-being.
- 11:22As we wrap up today's episode, I hope these tips inspire you to make your Thanksgiving meal
- 11:28not only memorable but also aligned with healthier, blue zone principles.
