Transcript
- 0:00Welcome to Morning Medical with Dr.
- 0:01Chow, your daily dose of the latest medical and health news from around the globe.
- 0:06I'm Dr.
- 0:06Chi-Ming Chow, your host, and today we're going to dive into some fascinating developments in
- 0:12the world of health.
- 0:13As always, our aim is to keep you informed and empowered about your health choices.
- 0:19Let's get started!
- 0:20Today, we're talking about a significant update in the management of high blood pressure, a
- 0:28condition that affects millions of Americans.
- 0:31According to a new study, nearly one in three adults in the United States with untreated high
- 0:36blood pressure could benefit from medication but aren't receiving it.
- 0:40This is largely due to newly expanded guidelines from the American Heart Association
- 0:44and the American College of Cardiology, which redefine an adult's risk for cardiovascular
- 0:49disease.
- 0:51The study's lead author, Dr.
- 0:53Mustafa Al-Jarshawi, a cardiologist at Keele University in England, highlights that if these
- 0:58guidelines are followed, approximately 200,900 all-cause deaths and 162,600 cardiovascular
- 1:06deaths could be prevented over the next decade.
- 1:09The guidelines suggest that blood pressure should ideally be below 120 millimeters of
- 1:15mercury systolic and 80 millimeters of mercury diastolic.
- 1:20For those with a blood pressure around 130 over 80, lifestyle changes have traditionally been
- 1:27recommended.
- 1:29However, with the new guidelines, more aggressive medication treatment is advised for
- 1:34some individuals.
- 1:36The American Heart Association's new PREVENT tool considers various factors like blood
- 1:41sugar, kidney function, and a person's risk for heart disease over the next ten years alongside
- 1:47blood pressure.
- 1:48This comprehensive approach means that around eighty-one million Americans might now be
- 1:53eligible for blood pressure-lowering medication.
- 1:57Dr.
- 1:57Andrew Freeman, a cardiologist not involved with the study, emphasizes that people who
- 2:02weren't previously considered high-risk might now be treated more aggressively.
- 2:06High blood pressure is often referred to as the silent killer, and expanding treatment could
- 2:12save countless lives.
- 2:15The study, published in the Journal of the American Heart Association, analyzed data from
- 2:20the National Health and Nutrition Examination Survey between 2009 and 2018.
- 2:28The researchers examined how death rates might be lower if the 2025 hypertension guidelines
- 2:34were applied.
- 2:36They found that among eighty-one million adults with high blood pressure but no cardiovascular
- 2:41disease, nearly 23 million could be newly eligible for treatment under the new
- 2:48guidelines, with nearly 9.7 million of them currently untreated.
- 2:54Receiving treatment could lower the risk of death by 23%, and the risk of heart-related
- 3:00death by 50%.
- 3:03Individuals with diabetes, in particular, would benefit significantly, as diabetes and high
- 3:10blood pressure often co-occur, increasing the risk of cardiovascular issues.
- 3:14Dr.
- 3:16Al-Jarshawi advises that anyone eligible for medication should not hesitate to start
- 3:22treatment, along with making lifestyle changes to mitigate long-term risks.
- 3:28Controlling high blood pressure is a long-term commitment to health, and it's important to
- 3:32address factors like physical activity, diet, substance use, stress levels, and maintaining a
- 3:38healthy weight.
- 3:40Dr.
- 3:41Leana Wen, an emergency physician and adjunct associate professor at George Washington
- 3:46University, suggests starting with small lifestyle changes.
- 3:50For instance, while reducing stress might be challenging, incorporating more fruits and
- 3:55vegetables into your diet could be an easier first step.
- 3:59The study's findings stress the importance of controlling high blood pressure, with Dr.
- 4:04Freeman noting that high blood pressure amplifies various health risks, making
- 4:09aggressive management a straightforward yet impactful approach.
- 4:13It's crucial to remember that medication only works if taken regularly.
- 4:18Unfortunately, about half of adults with high blood pressure in the United States don't
- 4:23consistently take their prescribed medication.
- 4:26Dr.
- 4:27Freeman recommends forming habits, such as placing your pillbox next to your toothbrush or
- 4:32alarm, to ensure you don't forget your medication.
- 4:36Keeping a small supply in your purse, wallet, or car can also serve as a helpful reminder.
- 4:43Finally, the study underscores the need for healthcare providers to be vigilant about early
- 4:50signs of disease and consider blood pressure treatment even in younger populations.
- 4:56As we see more young people with chronic conditions like diabetes, it's essential to be
- 5:03proactive and aggressive in managing these risks.
- 5:07The take-home message here is clear: controlling high blood pressure is vital, and
- 5:12with the right approach, it's a manageable and impactful step towards better health.
- 5:20In recent news, there’s been a notable trend of American doctors relocating to work in remote
- 5:24communities in British Columbia, Canada.
- 5:26One physician, Dr.
- 5:28Leo Bay, is among those making the transition from the United States to the Sunshine Coast of
- 5:34British Columbia.
- 5:35Dr.
- 5:36Bay and his family are preparing to leave their home in Utah for a new life in Canada, where he
- 5:41will practice as a family doctor at the Pender Harbour Health Centre.
- 5:46Dr.
- 5:46Bay expressed that the move is both significant and exciting for his family.
- 5:51Upon visiting Pender Harbour, he and his family instantly fell in love with the Sunshine Coast,
- 5:55which offers a natural environment they appreciate.
- 5:59They come from a rural area in Utah, which they believe will make their transition smoother as
- 6:04they enjoy outdoor activities.
- 6:06Dr.
- 6:07Bay has been practicing medicine for eight years, with experience in working with remote
- 6:11communities.
- 6:12He has held the position of associate chief medical information officer across several
- 6:17states.
- 6:18By the end of August, he is set to begin his new role, providing care to approximately one
- 6:23thousand residents in the remote coastal community of British Columbia.
- 6:29One of the reasons Dr.
- 6:30Bay decided to move to Canada involves the healthcare system differences between the
- 6:35United States and Canada.
- 6:37He noted that the complexities of insurance in the United States often pose challenges for
- 6:42primary care doctors.
- 6:44In contrast, he looks forward to focusing more on patient care in Canada.
- 6:51The transition for U.S.
- 6:52doctors to practice in British Columbia has been facilitated by changes in licensing
- 6:57requirements.
- 6:58As of July 2025, the College of Physicians and Surgeons of British Columbia implemented bylaw
- 7:04changes allowing U.S.-trained doctors to become fully licensed without needing further
- 7:08assessment or examination, provided they hold certain U.S.
- 7:12certifications.
- 7:14British Columbia's Ministry of Health has actively recruited healthcare professionals
- 7:18from the United States, receiving thousands of applications.
- 7:22They launched a digital advertising campaign targeting healthcare workers in states like
- 7:27Washington, Oregon, and California, highlighting the opportunities available in
- 7:32British Columbia.
- 7:34Dr.
- 7:34Bay will join another American doctor at the Pender Harbour Health Centre, Dr.
- 7:39Derek Williams, who moved from Montana.
- 7:42The clinic, which previously had only one part-time physician for five hundred people,
- 7:47will now be better equipped to serve the community with these new additions.
- 7:52The Pender Harbour Health Centre has recently undergone extensive renovations, funded by
- 7:57community donations, to accommodate the new physicians and improve healthcare services.
- 8:04This development is part of a broader effort to address the doctor shortage in British
- 8:08Columbia, which has been a longstanding issue.
- 8:12Overall, these changes reflect a significant shift in the healthcare landscape of British
- 8:17Columbia, as more U.S.
- 8:19healthcare professionals see Canada as a viable option for their careers, drawn by both
- 8:24professional opportunities and lifestyle benefits.
- 8:29In a groundbreaking announcement, the Federal Minister of Health, Marjorie Michel, has
- 8:34pledged twenty-four million dollars to establish the Canadian Cannabis and Brain
- 8:39Health Consortium.
- 8:41This initiative, funded through the Canadian Institutes of Health Research, aims to deepen
- 8:46our understanding of cannabis's impact on mental health and pregnancy.
- 8:51The consortium will unite ten research teams from across Canada, focusing on how cannabis
- 8:56affects the brain in people of various ages.
- 9:00The consortium's goal is to generate scientific evidence regarding both the potential benefits
- 9:05and harms of cannabis use.
- 9:08Their research will cover a wide range of topics, including its effects on conditions
- 9:12like epilepsy, anxiety, post-traumatic stress disorder, sleep, mental health, and brain
- 9:19development in youth and during pregnancy.
- 9:22This comprehensive approach is crucial, as the legalization of cannabis in 2018 has left many
- 9:28questions unanswered about its long-term health impacts.
- 9:31Dr.
- 9:33Patricia Conrod, the scientific director at the Institute of Neurosciences, Mental Health and
- 9:38Addiction at the Canadian Institutes of Health Research, emphasized the importance of this
- 9:42research.
- 9:44The team plans to recruit over three thousand participants of all ages, collecting extensive
- 9:50data on brain function, mental health, and substance use across the lifespan.
- 9:55This data will be made available to other Canadian researchers, fostering a collaborative
- 10:00environment for further studies on cannabis.
- 10:03Dr.
- 10:04Conrod noted that while Canadian research on cannabis has increased since its legalization,
- 10:10significant gaps in knowledge remain.
- 10:12She highlighted the consortium's role in bringing together Canada's top brain health and
- 10:17cannabis researchers to advance our understanding of cannabis's potential effects
- 10:22on the population.
- 10:23This initiative is expected to propel the field to new heights, providing insights into both
- 10:29the benefits and risks associated with cannabis use.
- 10:33The research teams leading this consortium hail from prestigious institutions, including the
- 10:38Université de Sherbrooke, Université de Montréal, McGill University, Dalhousie
- 10:44University, McMaster University, University of Waterloo, and the University of Calgary.
- 10:51By pooling their expertise, these teams aim to build a robust body of evidence that will guide
- 10:57future policies and healthcare practices related to cannabis.
- 11:03In today's segment, we're delving into an intriguing perspective from an emergency
- 11:08physician, Dr.
- 11:09Mary Meyer, who advocates for the inclusion of air conditioning as a prescribed measure in
- 11:14healthcare.
- 11:15Dr.
- 11:16Meyer recounts a personal experience that catalyzed her viewpoint.
- 11:20During a sweltering heat wave in Northern California, her elderly mother, who suffers
- 11:26from dementia, faced the dangerous predicament of a failed air conditioning system.
- 11:31This incident underscored for Dr.
- 11:34Meyer the critical role of air conditioning in safeguarding vulnerable populations against
- 11:39heat-related health crises.
- 11:41The connection between extreme heat and health is not new, but it is increasingly pressing as
- 11:46heat waves grow more frequent and intense.
- 11:50Dr.
- 11:50Meyer highlights the stark increase in heat-related mortality in the United States,
- 11:55which saw a 117% rise between 1999 and 2023.
- 12:01She points out that certain groups, including the elderly, young children, pregnant women,
- 12:07and those with chronic health conditions, are particularly susceptible to the adverse effects
- 12:11of extreme heat.
- 12:13Interestingly, Dr.
- 12:15Meyer draws a parallel between prescribing medications for chronic diseases and
- 12:19prescribing air conditioning as a preventive measure against heat-related illnesses.
- 12:24She argues that just as medications like statins and inhalers are used to manage chronic
- 12:30conditions, air conditioning could serve as a crucial intervention to prevent heat-related
- 12:36mortality, especially in high-risk individuals.
- 12:40The effectiveness of air conditioning in reducing heat-related deaths is supported by
- 12:45data.
- 12:46For instance, the widespread adoption of residential air conditioning in the United
- 12:51States has significantly lowered the likelihood of premature death during heat waves.
- 12:56Dr.
- 12:56Meyer notes that air conditioning prevented an estimated 47,800 heat-related deaths among
- 13:03elderly Americans in 2019 alone.
- 13:07Moreover, having access to air-conditioned environments has been shown to reduce
- 13:12hospitalizations and is more effective than other heat mitigation strategies like fans or
- 13:16showers.
- 13:18However, not everyone has access to air conditioning.
- 13:21Dr.
- 13:22Meyer points out that roughly 35 million Americans live without it, with a significant
- 13:28portion of these households being low-income or belonging to marginalized ethnic groups.
- 13:34She advocates for broader access to air conditioning, suggesting that health systems
- 13:39and insurers should consider it a necessary health intervention, much like other preventive
- 13:44measures.
- 13:46Dr.
- 13:46Meyer also touches on the environmental concerns associated with air conditioning,
- 13:50acknowledging that it contributes to greenhouse gas emissions and energy consumption.
- 13:56Nevertheless, she remains hopeful that technological advancements will make air
- 14:00conditioning more environmentally sustainable and that urban design will evolve to better
- 14:05protect citizens from heat.
- 14:08To address the immediate need, innovative programs are emerging to increase access to air
- 14:14conditioning for vulnerable populations.
- 14:17Dr.
- 14:18Meyer cites the Clean Power Prescription program by Boston Medical Center, which helps
- 14:23offset utility costs for high-risk patients using solar energy credits.
- 14:29She also mentions that some states have begun allowing Medicaid to cover air conditioning
- 14:34units for those most at risk.
- 14:38Dr.
- 14:38Meyer concludes with a call to action, urging healthcare providers and insurers to recognize
- 14:43heat-related illness as a preventable condition that deserves the same attention as other
- 14:49chronic diseases.
- 14:51As heat waves become more common, she stresses the importance of proactive measures to protect
- 14:56those most vulnerable, ensuring that what happened to her mother does not happen to
- 15:01others.
- 15:04Today, we're exploring groundbreaking research that suggests cancer warning signs might appear
- 15:08in our DNA years before traditional blood tests can detect any issues.
- 15:13This fascinating study, published in the journal Cancer Discovery by the American
- 15:18Association for Cancer Research, followed thirty individuals with myeloproliferative
- 15:23neoplasms, a group of blood cancers where the bone marrow produces too many blood cells.
- 15:29The researchers monitored the DNA in the patients' blood and bone marrow for genetic
- 15:34changes.
- 15:35They examined whether these changes were associated with blood counts, stable disease,
- 15:40or progression to more severe conditions like myelofibrosis or acute leukemia.
- 15:46Interestingly, they found that patients with stable disease often had stable DNA without
- 15:52cancer-related genetic changes, suggesting a 'quiet' genetic profile might indicate a more
- 15:57stable condition.
- 16:00For those whose disease worsened, DNA changes were often evident years before routine blood
- 16:05tests detected any progression.
- 16:07This occurred as new abnormal cell groups emerged and grew.
- 16:11Of the participants, nine eventually developed acute myeloid leukemia, but their progression
- 16:16paths varied.
- 16:18Some accumulated harmful mutations gradually, while in others, leukemia seemed to arise from
- 16:23a separate group of abnormal cells.
- 16:26The study also explored the effects of common medications like hydroxyurea and azacitidine,
- 16:32used to control blood counts in people with these conditions.
- 16:36These drugs left recognizable DNA change patterns in blood cells, although the study
- 16:41found no evidence that they caused leukemia.
- 16:44An intriguing discovery was that some patients diagnosed with 'triple-negative' essential
- 16:50thrombocythemia, a condition generally classified as a blood cancer, showed no genetic
- 16:56signs of cancer.
- 16:58This raises the possibility that some patients might not actually have a malignant disease and
- 17:03may not need long-term cancer treatment.
- 17:07The study's small sample size is a limitation, and the findings show associations rather than
- 17:12establishing cause and effect.
- 17:15However, this research provides a striking demonstration that DNA changes may signal
- 17:21cancer development long before diagnosis.
- 17:24It marks a step toward precision medicine in blood cancer care, where a patient's genetic
- 17:29data could predict risk years in advance.
- 17:32Dr.
- 17:33Abhishek Chilkulwar, an oncologist with Orlando Health who wasn't involved in the study,
- 17:38highlighted the potential of this research.
- 17:41He noted that most people with these types of blood cancers can live with them for decades.
- 17:46This study suggests that these cancers may reveal their future course in a person's DNA
- 17:50long before any symptoms appear.
- 17:53The next step in this research is to pair early genetic detection with drugs designed to target
- 17:58specific mutations.
- 18:00This could potentially prevent or delay disease progression.
- 18:05Although the tools to act fully on this research aren't yet available, the direction is
- 18:09clear: closer monitoring and more frequent checks could provide a much-needed heads-up if
- 18:14a patient’s disease is heading in a dangerous direction.
- 18:18In conclusion, while the immediate application may be limited to closer monitoring, this
- 18:23research opens the door to a future where precision medicine could change how we approach
- 18:28blood cancer prevention and treatment.
- 18:31It's an exciting time in the field of oncology, and we look forward to seeing how these
- 18:36findings evolve.
- 18:38That's all for today's episode of Morning Medical with Dr.
- 18:41Chow.
