Welcome to Morning Medical with Dr.
0:02
Chow, your daily update on the latest medical and health news from around the world.
0:06
I'm Dr.
0:07
Chi-Ming Chow, your host for today.
0:09
Let's dive into today's top stories.
0:15
Our first story today comes from Health Canada, which has issued a strong warning against the
0:20
use of unauthorized, injectable peptide drugs that claim to offer benefits like weight loss,
0:25
anti-aging, or general wellness.
0:28
These drugs, which are often marketed online, can pose serious health risks.
0:34
Peptides are a category of drugs that, in Canada, are regulated as prescription
0:39
medications.
0:40
This means they should only be used if advised by a doctor and dispensed from a licensed
0:45
pharmacy.
0:46
However, there are many unauthorized peptide drugs being sold outside this regulatory
0:51
framework, and Health Canada is raising the alarm about their potential dangers.
0:57
Among the severe side effects linked to these unauthorized peptides are liver and kidney
1:02
damage, blood clots, and even cancerous tumors.
1:06
Additionally, these drugs might cause infections, allergic reactions, or contain
1:11
contaminants due to improper manufacturing processes.
1:15
Some examples of such peptides include BPC-157, CJC-1295, DSIP, and others like HGH and its
1:26
fragments.
1:28
Health Canada emphasizes that only medications with an eight-digit drug identification number
1:34
on their labels are approved for sale and use in Canada.
1:38
The agency maintains a Drug Product Database where these approved medications can be
1:43
verified.
1:44
They also caution that drugs marketed as 'for research use only' are not exempt from
1:50
regulatory requirements.
1:52
The agency is actively working with the Canada Border Services Agency to intercept
1:57
unauthorized shipments of these drugs into the country.
2:00
If you've used any of these unauthorized peptides and are experiencing adverse effects,
2:06
it's crucial to seek medical attention and report your experience to Health Canada.
2:12
The Ottawa Hospital has announced that it will be reducing its workforce by three percent in
2:17
the coming months.
2:18
This decision was communicated to staff via an email on Thursday, highlighting reductions
2:24
across various roles including management, non-union, support, executive, nursing, and
2:30
other health-care positions.
2:32
According to the hospital, financial pressures within the health-care sector have necessitated
2:37
these cuts.
2:39
In a statement provided to CBC News, the hospital explained that it has been striving to
2:44
alleviate budget pressures through several measures before resorting to staff reductions.
2:50
These measures included offering early retirement to eligible employees, freezing and
2:54
eliminating vacant positions, and transitioning to a more cost-effective provincial group
2:59
benefits plan.
3:01
Despite these efforts, the hospital acknowledged that some job reductions are
3:05
unavoidable.
3:07
The statement did not specify exactly how many positions will be impacted, nor did it provide
3:12
a timeline for when these reductions would occur.
3:16
However, the hospital stated that it is collaborating with unions to finalize the
3:20
specifics.
3:22
The Ottawa Health Coalition, represented by spokesperson Kevin Skerrett, expressed concern,
3:28
labeling the situation as a 'hospital system in crisis.' Skerrett attributed the cuts to
3:34
chronic underfunding from the provincial government, which he claims contradicts
3:39
promises to end hallway health care and address systemic issues.
3:43
Ontario's Ministry of Health had previously tasked hospitals facing budget deficits to
3:48
develop a three-year plan to balance their finances.
3:51
The Ottawa Hospital's decision is part of this broader mandate to find savings, though
3:56
Skerrett and others fear the cuts will adversely affect patient care.
4:01
The Canadian Union of Public Employees, representing about 4,300 health-care workers at
4:07
The Ottawa Hospital, echoed these concerns.
4:11
Union president Robert Gauthier warned that the cuts could particularly impact front-line staff
4:17
such as nurses and personal support workers.
4:21
Gauthier emphasized that The Ottawa Hospital is already struggling with high patient volumes
4:26
and long wait times due to existing staffing shortages.
4:30
He advocates for an increase in staff rather than a reduction, estimating that 250
4:36
additional positions are needed annually to maintain current service levels.
4:41
Meanwhile, the hospital maintains its commitment to providing specialized services
4:46
for emergencies, surgeries, clinics, and inpatient care, while seeking innovative and
4:52
efficient ways to deliver care to the community.
4:56
Our next story highlights a significant finding from a study linking the quality of plant-based
5:01
diets to dementia risk.
5:03
Simply eating more vegetarian foods may not be sufficient to lower dementia risk, according to
5:09
new research by Song-Yi Park, Doctor of Philosophy, from the University of Hawaii at
5:14
Manoa, and colleagues.
5:17
The study, published in the journal Neurology, indicates that the quality of plant-based diets
5:22
plays a crucial role in determining the risk of Alzheimer's disease and other dementias.
5:27
High-quality plant-based diets, which include whole grains, fruits, vegetables, nuts,
5:34
legumes, and tea or coffee, were associated with a lower risk of Alzheimer's disease and
5:39
other dementias.
5:41
Conversely, low-quality plant-based diets, characterized by refined grains, fruit juices,
5:46
potatoes, and added sugars, were linked to an increased risk of dementia.
5:51
The study found that people adhering to high-quality plant-based diets had a
5:55
significantly lower risk of dementia over nearly 11 years of follow-up compared to those
5:59
on low-quality diets.
6:02
The research was part of the Multiethnic Cohort Study, which involved 92,849 participants from
6:10
diverse backgrounds, including African American, Japanese American, Latino, Native
6:16
Hawaiian, and white individuals in Hawaii and California.
6:21
The participants' usual diets were assessed through a quantitative food frequency
6:26
questionnaire at the study's start between 1993 and 1996, and again at a 10-year follow-up
6:33
between 2003 and 2008.
6:36
Interestingly, the study highlighted that shifting eating habits to reduce low-quality
6:42
plant foods over time was tied to an eleven percent reduction in dementia risk.
6:48
However, those who increased their intake of low-quality plant foods over the same period
6:53
faced a twenty-five percent higher risk of developing dementia.
6:58
These findings underscore the importance of not just adopting a plant-based diet, but ensuring
7:04
that the diet is rich in high-quality foods.
7:09
The researchers also noted that the relationships between plant intake and dementia
7:13
risk were consistent across different age groups, races, ethnicities, and even among
7:18
those with the APOE4 gene, a known genetic risk factor for Alzheimer's disease.
7:24
This suggests that the benefits of high-quality plant-based diets are broadly applicable.
7:30
While plant-based diets have been associated with lower risks of coronary heart disease and
7:35
type 2 diabetes, this study adds to the evidence that diet quality is key when it comes
7:41
to cognitive health as well.
7:43
The study's use of diet indices, such as the overall plant-based diet index, the healthful
7:49
plant-based diet index, and the unhealthful plant-based diet index, helped differentiate
7:54
between the quality of plant-based diets.
7:58
It's important to acknowledge, as the researchers did, that food frequency
8:02
questionnaires can be subject to measurement errors and unknown risk factors may have
8:07
influenced the results.
8:09
Nonetheless, this study provides valuable insights into how dietary choices can impact
8:15
dementia risk and emphasizes the need to focus on the quality of plant-based foods for better
8:21
cognitive health.
8:24
Our next story dives into a fascinating trend that's been making waves across social media.
8:30
It's all about the name "Jessica" and how it's being used as a tool to calm toddlers during
8:36
tantrums.
8:38
This playful tactic has captured the attention of parents everywhere, with videos of the
8:43
technique going viral.
8:45
In these clips, parents call out "Jessica"—a person who doesn't actually exist—and almost
8:51
magically, their screaming toddlers become quiet and attentive.
8:57
This viral trend is rooted in the age-old parenting strategy of redirection.
9:03
Pediatrician Katie Lockwood, Doctor of Medicine, Master of Education, from Children's
9:08
Hospital of Philadelphia, explains that redirection is about offering something new and
9:13
desirable to divert a child's attention from what they're upset about.
9:18
The "Jessica" hack works by introducing a new focus, effectively helping children forget
9:24
their initial source of distress.
9:27
Ari Brown, Doctor of Medicine, a pediatrician based in Austin, Texas, and spokesperson for
9:32
the American Academy of Pediatrics, supports this view.
9:36
She notes that the tactic is all about changing the child's goal.
9:40
By shifting the focus, the child's mood can be altered, ideally resulting in a calmer and more
9:45
manageable situation.
9:48
However, as with any trend, there are important caveats.
9:53
Psychologist Kimberly Brooks, Doctor of Philosophy, from Children's National Hospital
9:58
in Washington, D.C., emphasizes the need for a follow-up after the child has calmed down.
10:04
She suggests acknowledging the child's feelings and providing support to help manage those
10:09
emotions.
10:11
This approach helps children learn how to express their emotions in a healthy way.
10:17
It's crucial to understand that the "Jessica" tactic, like other forms of distraction and
10:22
redirection, might not be effective in every situation.
10:26
For example, if a toddler is in physical pain, or if the child is older and has more developed
10:32
cognitive reasoning skills, this method might not be suitable.
10:36
Furthermore, overuse of the tactic can render it ineffective, as it loses its novelty and
10:43
becomes background noise.
10:46
Lockwood cautions against the potential harm of using this tactic too frequently.
10:51
Children need to learn how to express their emotions rather than being constantly
10:55
redirected.
10:56
We want to ensure that children know their emotions are valid and that we're present to
11:01
support them in expressing these feelings safely.
11:05
Brooks also warns against using the name "Jessica" directly at the child, as this could
11:10
escalate the situation rather than calm it.
11:13
If the tactic doesn't work for your child, it doesn't reflect on the child or the technique
11:18
itself.
11:20
Parents are encouraged to consult with child psychologists or pediatricians for personalized
11:25
advice on managing tantrums.
11:28
Tantrums are a normal part of early development, helping toddlers understand and
11:32
deal with frustration and disappointment.
11:35
It's a process that contributes to their growth and development.
11:39
Brown highlights that while the "Jessica" trend has sparked a conversation about positive
11:44
parenting, it's essential to remember that discipline is a gradual process, much like
11:49
planting seeds and waiting for them to grow.
11:54
Today's focus is on a recent study from Hong Kong that raises further doubts about the
11:59
cardiovascular safety of calcium supplements, particularly for individuals with established
12:05
cardiovascular disease.
12:08
This retrospective cohort study, published in the Journal of the American Heart Association,
12:13
examined the potential adverse effects of calcium supplementation on cardiovascular
12:18
health.
12:19
The study found that people with established cardiovascular disease who took calcium
12:24
supplements had a higher risk of recurrent cardiovascular events compared to those who did
12:29
not take these supplements.
12:31
Specifically, there were 184.9 events per 1,000 person-years among those on calcium
12:38
supplements, compared to 167.5 events per 1,000 person-years in the control group.
12:45
This translates to a hazard ratio of 1.10, indicating a ten percent increased risk of
12:51
recurrent cardiovascular events.
12:54
Interestingly, the study noted that this increased risk was associated with calcium
12:59
supplementation alone, not when calcium was combined with vitamin D.
13:05
The hazard ratio for calcium alone was 1.21, whereas for the combination of calcium and
13:11
vitamin D, it was 0.97, suggesting no increased risk.
13:17
The researchers, led by Ching-Lung Cheung, Doctor of Philosophy, from the University of
13:22
Hong Kong, suggest that vitamin D might mitigate the adverse effects of calcium on
13:27
cardiovascular health.
13:29
The study's authors urge caution in prescribing calcium supplements to patients with
13:35
cardiovascular disease, especially considering that most randomized controlled trials have not
13:41
been specifically designed to evaluate cardiovascular outcomes in these individuals.
13:47
They emphasize that a combination of calcium and vitamin D appears to be less concerning
13:53
than calcium alone.
13:56
Calcium supplements are widely used to prevent or treat calcium deficiency, which can lead to
14:02
osteoporosis.
14:04
However, the relationship between calcium intake and cardiovascular health has been
14:08
controversial.
14:10
The study highlights the potential link between circulating calcium levels and the development
14:15
of coronary artery calcification and aortic calcification, both of which are related to
14:20
recurrent cardiovascular events.
14:23
Furthermore, the study points out that vitamin D may play a role in reducing these risks.
14:28
Animal models have shown that vitamin D can regulate cholesterol and the inflammatory
14:33
process in vessel walls, which might explain its beneficial effects when combined with
14:38
calcium.
14:39
The researchers also note that vitamin D deficiency is common in Asian populations,
14:45
where dietary calcium intake tends to be lower, suggesting that correcting this deficiency
14:51
could improve cardiovascular outcomes for calcium users.
14:56
The study analyzed data from individuals aged 40 years and older who were newly diagnosed
15:01
with cardiovascular disease between 2006 and 2015.
15:07
The treatment group consisted of over 38,000 people prescribed calcium supplements, either
15:12
alone or with vitamin D, while the control group included nearly 193,000 individuals who
15:19
had never been prescribed calcium supplements.
15:22
Through propensity score matching, researchers created a balanced cohort for comparison.
15:28
The findings showed that men taking calcium supplements had a higher association with
15:32
recurrent cardiovascular events compared to women, and there was also a greater likelihood
15:36
of cardiovascular-related hospitalizations among calcium users.
15:40
However, the study acknowledged potential limitations, such as residual confounding and
15:46
potential misclassification due to over-the-counter calcium supplement use, which
15:51
could underestimate the risk.
15:54
Overall, this study adds to the ongoing debate about the safety of calcium supplements for
16:00
heart health, particularly in individuals with existing cardiovascular conditions.
16:06
It underscores the importance of considering vitamin D supplementation alongside calcium to
16:11
potentially mitigate risks, especially in populations prone to vitamin D deficiency.
16:18
Our final story today delves into a promising study that suggests a common vaccine could
16:24
significantly reduce the risk of Alzheimer's disease when the dose is increased.
16:29
This research, conducted by the University of Texas Health Science Center at Houston,
16:34
highlights the potential benefits of a high-dose influenza vaccine for older adults.
16:40
According to the study, adults aged 65 and older who received a high-dose flu vaccine
16:46
showed a substantially lower risk of developing Alzheimer's disease compared to those who
16:52
received the standard dose.
16:54
The high-dose vaccine is formulated to be about four times stronger than the regular flu shot,
17:00
which is particularly important as the immune system naturally weakens with age, making older
17:06
adults less responsive to standard vaccines.
17:10
The Centers for Disease Control and Prevention recommends this high-dose flu vaccine for
17:15
individuals over 65 as a proactive measure to enhance their immune response.
17:21
The study found that those who received the high-dose vaccine had an almost fifty-five
17:26
percent lower risk of developing Alzheimer's disease than those who did not receive any
17:31
vaccination, and a significantly lower risk compared to those who received the standard
17:35
dose.
17:37
Interestingly, the protective effect of the high-dose vaccine was more pronounced in women
17:43
than in men, although both genders benefited from the increased dosage.
17:48
This suggests that the immune response elicited by the high-dose vaccine might play a crucial
17:53
role in reducing Alzheimer's risk, potentially by decreasing inflammation in the body.
17:59
It's important to note that the study does not establish a direct cause-and-effect
18:04
relationship between the high-dose flu vaccine and reduced Alzheimer's risk.
18:09
The researchers caution that while a correlation exists, other factors such as
18:14
healthier lifestyle choices could also contribute to the observed benefits.
18:19
People who opt for high-dose vaccines might generally engage in healthier behaviors, like
18:24
maintaining a balanced diet or attending regular health check-ups.
18:28
The study primarily focused on individuals over 65, leaving open the question of whether
18:34
receiving high-dose flu vaccines earlier in life could offer similar protective benefits.
18:40
Furthermore, the research relied on retrospective data analysis, which can
18:45
sometimes lead to biases or missing information, underscoring the need for further
18:50
prospective studies to confirm these findings.
18:53
Despite these limitations, this study adds another compelling reason to consider receiving
18:58
a flu shot, particularly the high-dose version for those eligible.
19:02
The potential to significantly lower Alzheimer's risk is an exciting prospect that
19:07
warrants further exploration and could be a valuable tool in our ongoing efforts to combat
19:12
this debilitating disease.
19:15
And that brings us to the end of today's episode.
19:18
