  Good morning, everyone, and welcome to another episode of Morning Medical with Dr.
• 0:05
  Chow.
• 0:06
  I'm your host, Dr.
• 0:07
  Chi-Ming Chow, and today we're diving into some intriguing findings regarding smartphone usage
• 0:13
  among adolescents during school hours.
• 0:16
  This comes from a recent study that sheds light on how much time teens are really spending on
• 0:20
  their phones while in class.
• 0:25
  According to the Adolescent Brain Cognitive Development study, U.S.
• 0:29
  adolescents are spending over an hour each school day on their smartphones.
• 0:33
  This study utilized passive measurement software on the phones of 640 teens, providing
• 0:40
  a clearer picture of their actual usage.
• 0:44
  On average, these adolescents spent about 1.16 hours per school day using their smartphones.
• 0:50
  Social media apps like Instagram, TikTok, and Snapchat topped the usage list, with teens
• 0:56
  spending nearly 30 minutes a day on these platforms.
• 0:59
  This was followed by video apps like YouTube and gaming apps such as Roblox and Pokemon GO.
• 1:06
  Dr.
• 1:07
  Jason Nagata from the University of California San Francisco, who led the study, pointed out
• 1:12
  that while school phone policies are evolving rapidly, there's been little objective data on
• 1:17
  what students are actually doing with their phones during school hours.
• 1:21
  This new data moves the conversation beyond anecdotal reports and self-reported screen time
• 1:27
  to real-world behavior.
• 1:30
  Dr.
• 1:31
  Nagata emphasizes that smartphones, while they can support learning and connection, may also
• 1:36
  serve as a significant distraction if not managed properly.
• 1:41
  Interestingly, the study highlighted that higher smartphone and social media usage at
• 1:46
  school were more prevalent among older teens, those of Black or other racial backgrounds, and
• 1:52
  those from lower-income households.
• 1:54
  This points to a complex interplay of social and economic factors influencing phone use
• 1:59
  during school.
• 2:01
  In a related survey by Dr.
• 2:03
  Dimitri Christakis and colleagues, which included over 35,000 adults globally, 76.2%
• 2:10
  agreed that smartphones should be banned during school hours.
• 2:14
  Among U.S.
• 2:15
  parents, 71.3% were in favor of such bans.
• 2:20
  The survey revealed that factors like female gender, being a parent, older age, and higher
• 2:26
  life satisfaction were associated with supporting a ban on smartphones during school
• 2:31
  hours.
• 2:32
  Interestingly, those who felt they spent too much time online also tended to support these
• 2:37
  bans.
• 2:39
  While the study predominantly analyzed data from Android users, it raises important
• 2:43
  questions about how changing school smartphone policies might influence adolescent behavior
• 2:48
  and academic outcomes over time.
• 2:51
  As these regulations continue to evolve, periodic analysis will be crucial to
• 2:56
  understanding these dynamics.
• 2:59
  This study offers a fascinating glimpse into the digital lives of our adolescents and
• 3:03
  underscores the importance of balancing technology use with educational priorities.
• 3:09
  We'll continue to monitor how these trends develop and what they mean for both students
• 3:13
  and educators alike.
• 3:17
  As we transition into our next topic, let's turn our attention to a pressing issue
• 3:22
  impacting health care systems across the United States.
• 3:25
  The New York State Department of Health recently announced that the state has hit an
• 3:29
  all-time high for flu hospitalizations in a single week.
• 3:34
  This concerning development was confirmed in a press release dated January second, as flu
• 3:39
  cases continue to surge both in New York and nationwide.
• 3:44
  New York State, which includes New York City, has consistently reported the highest numbers
• 3:49
  of respiratory illness cases in the country over the past few weeks, according to the
• 3:54
  Centers for Disease Control and Prevention data.
• 3:58
  Several other states have also reached the "very high" category for respiratory activity
• 4:03
  as of the week ending December twenty-seventh.
• 4:06
  The most recent data from the New York health department showed a staggering four thousand
• 4:11
  five hundred forty-six hospitalizations from December twenty-sixth, two thousand
• 4:16
  twenty-five, to January second, two thousand twenty-six.
• 4:20
  This represents a week-over-week increase of nearly one thousand hospitalizations.
• 4:26
  Just the prior week, the department had announced the highest number of flu cases ever
• 4:30
  recorded in a single seven-day period.
• 4:34
  Acting Commissioner of Health, Dr.
• 4:36
  James McDonald, emphasized the severity of this flu season compared to previous years.
• 4:43
  He confirmed, "Almost one thousand more people were admitted to a hospital during this most
• 4:48
  recent seven-day period compared to the prior week." Dr.
• 4:51
  McDonald also stressed the importance of getting a flu shot, reminding the public that
• 4:56
  flu can be treated with antiviral medication if started within forty-eight hours of symptom
• 5:01
  onset, as deemed appropriate by your doctor.
• 5:05
  Health officials are urging Americans to consider the flu vaccine as it is regarded as a
• 5:09
  top line of defense against viral exposure and spread.
• 5:13
  Common flu symptoms include fever, chills, headache, fatigue, cough, sore throat, and
• 5:20
  runny nose.
• 5:21
  Dr.
• 5:22
  Neil Maniar, a professor of public health practice at Boston’s Northeastern University,
• 5:27
  emphasized in an interview that it's not too late to get the flu vaccine, as the peak season
• 5:32
  typically occurs in January.
• 5:36
  Dr.
• 5:37
  Maniar pointed out that the vaccine still offers protection against serious illness
• 5:42
  resulting from the subclade K variant, which seems to be prevalent this season.
• 5:48
  He noted that even healthy individuals can become seriously ill from the flu, making the
• 5:54
  vaccine beneficial for almost everyone.
• 5:56
  Individuals typically start to develop some degree of protection within a few days and gain
• 6:01
  the full benefit within about two weeks, so now is the time for anyone who hasn’t gotten the
• 6:06
  vaccine yet.
• 6:08
  The New York State Department of Health recommends several preventive actions to avoid
• 6:12
  flu infection.
• 6:13
  These include washing hands frequently, avoiding touching the eyes, nose, and mouth,
• 6:19
  avoiding close contact with sick individuals, keeping objects and surfaces clean and
• 6:23
  disinfected, and staying home when feeling unwell.
• 6:28
  These measures, along with vaccination, can play a crucial role in managing this
• 6:33
  challenging flu season.
• 6:36
  Elon Musk's company, Neuralink, has announced an ambitious plan to begin high-volume
• 6:41
  production of its innovative brain implant device in 2026.
• 6:47
  This groundbreaking technology aims to connect the brain directly to a computer by
• 6:52
  interpreting electrical signals from neurons and translating them into digital commands.
• 6:58
  The ultimate goal is to enable users to control devices or regain lost functions purely through
• 7:05
  the power of their minds.
• 7:08
  The Neuralink implant utilizes electrodes placed near neurons in the brain to detect
• 7:13
  action potentials.
• 7:15
  This allows the device to decode the information represented by these neurons.
• 7:20
  As described on the Neuralink website, neurons in the brain's movement-related areas represent
• 7:26
  intended movements, and there are neurons that carry information about everything we see,
• 7:30
  feel, touch, or think.
• 7:32
  Remarkably, the chip is designed to be fully implantable and cosmetically invisible, with a
• 7:39
  thickness of just 1.75 inches.
• 7:42
  Neuralink's plans include a streamlined and almost entirely automated surgical procedure to
• 7:48
  implant these devices, which will involve threading the device through the dura without
• 7:52
  needing to remove it.
• 7:55
  Neuralink began human trials of its brain implant in 2024, following the resolution of
• 8:01
  safety concerns raised by the Food and Drug Administration.
• 8:05
  Although the initial application was rejected in 2022, the company has since moved forward
• 8:11
  with its research and development efforts.
• 8:14
  In a notable case, Brad Smith, a paralyzed man with amyotrophic lateral sclerosis, became the
• 8:21
  third person to receive a Neuralink implant.
• 8:24
  With this technology, he is now able to type using only his brain.
• 8:28
  Smith, who was diagnosed in 2020, shared a video demonstrating how he uses the
• 8:33
  brain-computer interface to control the mouse on his MacBook Pro, stating, "I am typing this
• 8:39
  with my brain.
• 8:40
  It is my primary communication."
• 8:43
  As of now, twelve individuals worldwide with severe paralysis have received Neuralink
• 8:49
  implants.
• 8:50
  These patients are using the implants to control both digital and physical tools through
• 8:55
  thought, showcasing the immense potential of this technology to transform lives.
• 9:03
  In our segment, "While You Were Gone," Dr.
• 9:06
  Fred Pelzman, a contributing writer for MedPage Today, provides a compelling perspective on the
• 9:12
  evolving landscape of patient care coverage during physician absences.
• 9:17
  As many of you know, balancing professional responsibilities with personal time can be
• 9:22
  quite a challenge, especially during holiday seasons when many people are away from the
• 9:26
  office.
• 9:28
  Dr.
• 9:29
  Pelzman reflects on his recent holiday break, where he enjoyed some downtime with his family.
• 9:33
  He highlights the vital role that nurse practitioners play in maintaining the
• 9:38
  continuity of care when physicians are unavailable.
• 9:41
  They handle medication refills, urgent visits, and critical follow-ups, ensuring that patients
• 9:45
  are not left without support.
• 9:48
  However, Dr.
• 9:49
  Pelzman acknowledges the limitations of off-hours coverage and reminisces about the
• 9:55
  days when an operator would simply offer to page an on-call doctor for emergencies.
• 10:00
  He shares a personal anecdote about a time when he covered for a senior partner who was on an
• 10:05
  extended vacation, emphasizing the overwhelming nature of managing a complex patient panel in
• 10:10
  such situations.
• 10:12
  The introduction of patient portals has been a double-edged sword.
• 10:16
  While they facilitate communication, they also create expectations for immediate responses,
• 10:22
  which can be challenging to meet, especially during peak seasons like the current cold and
• 10:27
  flu surge in New York.
• 10:29
  This adds to the already heavy workload of covering practitioners.
• 10:33
  Dr.
• 10:34
  Pelzman also touches on the increasing role of online clinical care programs.
• 10:38
  These systems can potentially bridge the gap during physician absences by managing simple
• 10:43
  outpatient issues, although they lack the nuanced understanding that comes from direct
• 10:48
  patient interaction.
• 10:49
  He envisions a future where these systems could complement human practitioners, providing
• 10:54
  valuable support and ensuring patient safety.
• 10:58
  As we look to the future, it's fascinating to consider how technology might evolve to support
• 11:03
  healthcare professionals, allowing them more flexibility while maintaining high standards of
• 11:09
  patient care.
• 11:10
  Dr.
• 11:10
  Pelzman’s insights remind us of the importance of finding balance and ensuring that our
• 11:15
  systems and practices continue to adapt to the ever-changing healthcare landscape.
• 11:21
  And with that, we've reached the end of today's episode.
• 11:25
  I hope you found these updates as intriguing as I did.
