ER Visits Before Cancer Diagnosis, Recurrent UTIs in Children, and AI in Healthcare · Morning Medical with Dr. Chow

• 0:00
  Welcome to Morning Medical with Doctor Chow, where we bring you the latest medical and
• 0:04
  health news from around the world.
• 0:05
  I'm Doctor Chi-Ming Chow, a cardiologist and Professor of Medicine at the University of
• 0:10
  Toronto.
• 0:11
  Today, we're diving into a concerning trend highlighted by a recent study: many Canadians
• 0:17
  are ending up in emergency rooms before being diagnosed with cancer.
• 0:24
  A study published in the Canadian Medical Association Journal has revealed that more than
• 0:29
  a third of cancer patients in Ontario visited an emergency department within the three months
• 0:34
  leading up to their cancer diagnosis.
• 0:38
  This is a significant finding that underscores the challenges faced by patients during the
• 0:43
  diagnostic phase of their cancer journey.
• 0:46
  According to Doctor Keerat Grewal, a study co-author and an emergency medicine physician
• 0:51
  at Mount Sinai Hospital in Toronto, it's almost one in three patients who are using the
• 0:57
  emergency department prior to their diagnosis.
• 1:00
  The study analyzed data from over 650,000 patients who were first diagnosed with cancer
• 1:06
  between 2014 and 2021 in Ontario.
• 1:10
  Even though the data is specific to Ontario, Doctor Grewal notes that this trend is being
• 1:16
  observed across Canada.
• 1:19
  Among the patients who visited emergency departments 90 days before receiving a cancer
• 1:25
  diagnosis, 64 percent had visited once, 23 percent visited twice, and 13 percent had three
• 1:33
  or more visits.
• 1:35
  Notably, more than half of these patients were hospitalized following their emergency room
• 1:39
  visit.
• 1:41
  The research highlighted that older patients, those living in rural or northern parts of
• 1:46
  Ontario, and patients diagnosed with specific types of cancer such as brain, pancreatic,
• 1:53
  liver, gallbladder, or thoracic cancers were more likely to visit the emergency department.
• 1:59
  This trend raises questions about access to primary care and the effectiveness of existing
• 2:04
  diagnostic pathways.
• 2:07
  Doctor Grewal explained that there are various reasons why cancer patients might end up in the
• 2:12
  emergency department before their diagnosis.
• 2:16
  Some patients might present with symptoms that strongly suggest cancer, such as coughing up
• 2:21
  blood, which may lead to a suspected lung cancer diagnosis.
• 2:25
  Others might be seeking to expedite follow-up care after a suspected diagnosis from a walk-in
• 2:31
  clinic or family doctor.
• 2:34
  However, the emergency department is often not the ideal setting for diagnosing cancer.
• 2:41
  Emergency physicians may have strong suspicions based on bloodwork or imaging but are generally
• 2:46
  not equipped to provide a definitive diagnosis or follow-up care.
• 2:52
  This gap in the healthcare system suggests a need for more streamlined pathways for cancer
• 2:57
  diagnosis, whether initiated from primary care or emergency departments.
• 3:03
  As we consider these findings, it's clear that more research is needed to understand why
• 3:08
  certain patient populations are more likely to use the emergency department.
• 3:12
  With an estimated 247,100 new cancer cases and 88,100 cancer deaths projected in Canada for
• 3:21
  2024, improving diagnostic pathways and access to care is more important than ever.
• 3:27
  A recent meta-analysis has brought some encouraging news for children struggling with
• 3:31
  recurrent urinary tract infections, or RUTI.
• 3:34
  The study, which analyzed data from 23 randomized controlled trials involving 3,335
• 3:41
  participants, suggests that both the antibiotic nitrofurantoin and cranberry products can
• 3:47
  significantly decrease the incidence of symptomatic urinary tract infection episodes in
• 3:52
  these children.
• 3:54
  Nitrofurantoin stood out in the analysis, showing a significant reduction in the odds of
• 3:58
  symptomatic urinary tract infection episodes when used as a prophylactic measure.
• 4:04
  Specifically, it was found to be more effective compared to control groups and even when
• 4:09
  compared to other antibiotics such as trimethoprim and sulfamethoxazole.
• 4:13
  The odds ratio for nitrofurantoin compared to controls was 0.21, indicating a substantial
• 4:20
  decrease in risk.
• 4:22
  Interestingly, cranberry juice or tablets also demonstrated a noteworthy effect, reducing the
• 4:28
  odds of symptomatic urinary tract infection episodes by 59 percent compared to controls.
• 4:35
  The odds ratio for cranberry products was reported as 0.41, highlighting their potential
• 4:41
  as a non-antibiotic option for managing recurrent urinary tract infections in children.
• 4:48
  The study, led by Doctor Nikolaos Gkiourtzis and colleagues from Aristotle University of
• 4:53
  Thessaloniki in Greece, emphasizes the importance of exploring non-antibiotic options
• 4:59
  for preventing recurrent urinary tract infections.
• 5:03
  In a commentary accompanying the study, Doctors Joshua Watson and Jason Newland from Nationwide
• 5:09
  Children's Hospital in Columbus, Ohio, noted the negative consequences associated with
• 5:15
  long-term antibiotic use, such as increasing antibiotic resistance.
• 5:20
  They described the findings related to cranberry products as exciting and encouraging.
• 5:26
  While low-dose antibiotics have been shown to provide some benefit in preventing repeated
• 5:31
  urinary tract infection episodes by inhibiting bacterial growth, there is a concurrent risk of
• 5:38
  developing antibiotic resistance.
• 5:41
  As such, the Cochrane Systematic Review suggests reserving long-term antibiotic
• 5:46
  prophylaxis for children at high risk for recurrent urinary tract infections.
• 5:51
  Despite the promising results, the study authors caution that no prophylaxis option,
• 5:56
  including nitrofurantoin and cranberry products, can eliminate the risk of kidney
• 6:02
  scarring after recurrent urinary tract infections.
• 6:05
  Febrile urinary tract infections and acute pyelonephritis in children can lead to kidney
• 6:11
  scar formation, which poses a risk for future complications.
• 6:16
  The meta-analysis compared nine different interventions, including some other
• 6:20
  alternatives like lactobacillus, vitamin D, and cefprozil, but nitrofurantoin was ranked as the
• 6:26
  best option for reducing urinary tract infection incidence.
• 6:30
  However, the researchers noted that many of the other interventions did not achieve statistical
• 6:34
  significance in reducing urinary tract infection incidence.
• 6:39
  The study's participants had a mean age ranging from 3.8 to 14.7 years, and the trials were
• 6:46
  conducted across various regions, including Europe, Asia, the United States, Argentina, and
• 6:53
  Australia, between 1975 and 2023.
• 6:58
  The researchers pointed out that a significant number of these studies were considered to have
• 7:03
  a high risk of bias, highlighting the need for further research with optimal methodologies.
• 7:09
  The authors of the study call for more research to determine the optimal formulation, dosage,
• 7:15
  and patient population for cranberry products and other non-antibiotic options.
• 7:20
  They emphasize that treatment decisions should be individualized based on the patient's
• 7:25
  profile.
• 7:26
  Looking forward, there is potential for other non-antibiotic options such as probiotics,
• 7:32
  methenamine, and D-mannose, which have not yet been adequately studied in children.
• 7:37
  Additionally, vaccine development for recurrent urinary tract infection prevention is underway
• 7:42
  and may offer a powerful tool in the future.

  As we delve into the realm of robotics in healthcare, it's clear that while robots may
• 16:12
  not be the immediate answer for primary care, there's significant potential in "smart
• 16:17
  systems" to enhance our existing medical practices.
• 16:23
  Fred Pelzman, an associate professor of medicine at Weill Cornell and a practicing
• 16:28
  internist, highlights this perspective in a recent article.
• 16:32
  In "The Empire Strikes Back," there's a memorable scene where Luke Skywalker receives a
• 16:37
  new hand after his confrontation with Darth Vader.
• 16:41
  This futuristic depiction of medical robotics sparks curiosity about the role of robots in
• 16:47
  our current healthcare landscape.
• 16:49
  While space medicine remains a topic for future exploration, today, robotics are beginning to
• 16:55
  establish a foothold in various medical fields.
• 16:59
  Currently, robotics have made notable strides in areas like surgery, where the Da Vinci
• 17:04
  surgical robot enables surgeons to perform precise operations from afar.
• 17:10
  There are also fascinating developments in microscopic robots designed to navigate

  care and self-management.
• 18:08
  Imagine a smart system that helps patients manage their health at home—reminding them to
• 18:14
  take medications, track blood pressure, or adhere to physical therapy routines.
• 18:20
  Such systems could significantly benefit patients with chronic conditions, even
• 18:25
  assisting with tasks like wound care and fall prevention.
• 18:29
  While a robot replacing a physician is not imminent, there's ample opportunity to
• 18:34
  creatively integrate smart systems into healthcare.
• 18:37
  These innovations could enhance patient adherence to medical advice, improve health
• 18:41
  outcomes, and foster a healthier society.
• 18:44
  Perhaps not as dramatic as a robotic hand replacement, but certainly impactful in
• 18:50
  everyday healthcare.
• 18:52
  As we continue to explore the possibilities of robotics and smart systems, we must remain open
• 18:57
  to innovation and thoughtful implementation.
• 19:01
  By doing so, we can create a more supportive healthcare environment where patients receive
• 19:06
  the care they need, even outside the doctor's office.
