In a recent survey of 1259 mothers published in the journal Pediatrics, 28% reported they had fallen asleep while feeding their babies, and 83% of those mothers reported that the sleep was unplanned. Although the study sample was small, the investigators found that sociodemographic factors did not increase the odds that a mother would fall asleep while feeding.

These numbers are not surprising, but nonetheless they are concerning because co-sleeping is a known risk factor for sudden unexplained infant death (SUID). Every parent will tell you during the first 6 months of their adventure in parenting they didn’t get enough sleep. In fact some will tell you that sleep deprivation was their chronic state for the child’s first year. 

 

Falling asleep easily at times and places not intended for sleep is the primary symptom of sleep deprivation. SUID is the most tragic event associated with parental sleep deprivation, but it is certainly not the only one. Overtired parents are more likely to be involved in accidents and are more likely to make poor decisions, particularly those regarding how to respond to a crying or misbehaving child.

The investigators found that 24% of mothers who reported that their usual nighttime feeding location was a chair or sofa (14%). Not surprisingly, mothers who fed in chairs were less likely to fall asleep while feeding. Many of these mothers reported that they chose the chair because they thought they would be less likely to fall asleep and/or disturb other family members. One wonders how we should interpret these numbers in light of other research that has found it is “relatively less hazardous to fall asleep with an infant in the adult bed than on a chair or sofa.” Had these chair feeding mothers made the better choice under the circumstances? It would take a much larger and more granular study to answer that question.

Mothers who exclusively breastfed were more likely to fall asleep feeding than were those who partially breastfed or used formula. The investigators postulated that the infants of mothers who exclusively breastfed may have required more feedings because breast milk is more easily and quickly digested. I know this is a common explanation, but in my experience I have found that exclusively breastfed infants often use nursing as pacification and a sleep trigger and spend more time at the breast regardless of how quickly they emptied their stomachs.

This study also examined the effect of repeated educational interventions and support and found that mothers who received an intervention based on safe sleep practices were less likely to fall asleep while feeding than were the mothers who had received the intervention focused on exclusive breastfeeding value and barriers to its adoption.

Certainly, the problem of mothers falling asleep while feeding is one we should address more robustly than we have in the past. Education is one avenue, particularly when it includes the mother’s partner who can play an important role as standby lifeguard to make sure the mother doesn’t fall asleep. Obviously, this is easier said than done because when there is a new baby in the house sleep deprivation is usually a shared experience.

Although I believe that my family is on the verge of gifting me a smartwatch to protect me from my own misadventures, I don’t have any personal experience with these wonders of modern technology. However, I suspect with very little tweaking a wearable sensor could be easily programmed to detect when a mother is beginning to fall asleep while she is feeding her infant. A smartwatch would be an expensive intervention and is unlikely to filter down to economically challenged families. On the other hand, this paper has reinforced our suspicions that sleep-deprived infant feeding is a significant problem. A subsidized loaner program for those families that can’t afford a smartwatch is an option that should be considered.

When a patient signs on to a telehealth portal, there’s little more a provider can do than ask questions. But a new artificial intelligence (AI) technology could allow providers to get feedback about the patient’s blood pressure and diabetes risk just from a video call or a smartphone app.

Researchers at the University of Tokyo in Japan are using AI to determine whether people might have high blood pressure or diabetes based on video data collected with a special sensor. 

The technology relies on photoplethysmography (PPG), which measures changes in blood volume by detecting the amount of light absorbed by blood just below the skin. 

This technology is already used for things like finger pulse oximetry to determine oxygen saturation and heart rate. Wearable devices like Apple Watches and Fitbits also use PPG technologies to detect heart rate and atrial fibrillation.

“If we could detect and accurately measure your blood pressure, heart rate, and oxygen saturation non-invasively that would be fantastic,” said Eugene Yang, MD, professor of medicine in the division of cardiology at the University of Washington School of Medicine in Seattle who was not involved in the study.

 

How Does PPG Work — and Is This New Tech Accurate?

Using PPG, “you’re detecting these small, little blood vessels that sit underneath the surface of your skin,” explained Yang.

“Since both hypertension and diabetes are diseases that damage blood vessels, we thought these diseases might affect blood flow and pulse wave transit times,” said Ryoko Uchida, a project researcher in the cardiology department at the University of Tokyo and one of the leaders of the study.

PPG devices primarily use green light to detect blood flow, as hemoglobin, the oxygen-carrying molecule in blood, absorbs green light most effectively, Yang said. “So, if you extract and remove all the other channels of light and only focus on the green channel, then that’s when you’ll be able to potentially see blood flow and pulsatile blood flow activity,” he noted.

The University of Tokyo researchers used remote or contactless PPG, which requires a short video recording of someone’s face and palms, as the person holds as still as possible. A special sensor collects the video and detects only certain wavelengths of light. Then the researchers developed an AI algorithm to extract data from participants’ skin, such as changes in pulse transit time — the time it takes for the pulse to travel from the palm to the face.

To correlate the video algorithm to blood pressure and diabetes risk, the researchers measured blood participants’ pressure with a continuous sphygmomanometer (an automatic blood pressure cuff) at the same time as they collected the video. They also did a blood A1c test to detect diabetes.

So far, they’ve tested their video algorithm on 215 people. The algorithm applied to a 30-second video was 86% accurate in detecting if blood pressure was above normal, and a 5-second video was 81% accurate in detecting higher blood pressure.

Compared with using hemoglobin A1c blood test results to screen for diabetes, the video algorithm was 75% accurate in identifying people who had subtle blood changes that correlated to diabetes.

“Most of this focus has been on wearable devices, patches, rings, wrist devices,” Yang said, “the facial video stuff is great because you can imagine that there are other ways of applying it.”

Yang, who is also doing research on facial video processing, pointed out it could be helpful not only in telehealth visits, but also for patients in the hospital with highly contagious diseases who need to be in isolation, or just for people using their smartphones. 

“People are tied to their smartphones, so you could imagine that that would be great as a way for people to have awareness about their blood pressure or their diabetes status,” Yang noted.

 

More Work to Do

The study has a few caveats. The special sensor they used in this study isn’t yet integrated into smartphone cameras or other common video recording devices. But Uchida is hopeful that it could be mass-produced and inexpensive to someday add.

Also, the study was done in a Japanese population, and lighter skin may be easier to capture changes in blood flow, Uchida noted. Pulse oximeters, which use the same technology, tend to overestimate blood oxygen in people with darker skin tones.

“It is necessary to test whether the same results are obtained in a variety of subjects other than Japanese and Asians,” Uchida said, in addition to validating the tool with more participants.

The study has also not yet undergone peer review.

And Yang pointed out that this new AI technology provides more of a screening tool to predict who is at high risk for high blood pressure or diabetes, rather than precise measurements for either disease.

There are already some devices that claim to measure blood pressure using PPG technology, like blood pressure monitoring watches. But Yang warns that these kinds of devices aren’t validated, meaning we don’t really know how well they work.

One difficulty in getting any kind of PPG blood pressure monitoring device to market is that the organizations involved in setting medical device standards (like the International Organization for Standards) doesn’t yet have a validation standard for this technology, Yang said, so there’s really no way to consistently verify the technology’s accuracy.

“I am optimistic that we are capable of figuring out how to validate these things. I just think we have so many things we have to iron out before that happens,” Yang explained, noting that it will be at least 3 years before a remote blood monitoring system is widely available.

For some medical students and trainees who go on to become hematologists, attraction to the field happens the first time they’re engrossed in figuring out what a blood smear is telling them. Others get drawn to hematology during a rotation in residency, when they encounter patients with hemophilia or sickle cell disease.

But when it comes to turning people on to the idea of a career in classical hematology (CH), there may be no more powerful influence than a mentor who loves their job. That’s why the field is focusing so much on supporting mentors and mentees amid a stark shortage of classical hematologists.

“Mentorship is key for maintaining trainee interest in the field and for providing role models for career growth,” said Rakhi P. Naik, MD, MHS, associate professor of medicine and director of the Hematology Fellowship Track at Johns Hopkins University, Baltimore, Maryland, in an interview. “This collaboration is especially critical because there are so few trainees and so few mentors currently in the field.”

Now there’s new research backing up the power of mentorship, even when it’s only provided virtually, and a brand-new program aims to unite more mentors and mentees.

Here’s a closer look at mentor-focused efforts to attract medical students to CH.

 

How Severe Is the Shortage in CH?

Patients with conditions treated by classical hematologists are waiting months for appointments at many outpatient centers, with some being forced to wait 6 months or more, said Srikanth Nagalla, MD, chief of benign hematology at Miami Cancer Institute, Florida, in an interview.

The shortage is creating dire problems in the inpatient setting too, Nagalla said. “Serious blood disorders like heparin-induced thrombocytopenia, acute chest syndrome [a complication of sickle cell disease], and thrombotic thrombocytopenic purpura have to be diagnosed and treated in a timely manner. If not, the morbidity and mortality are really high.”

If classical hematologists aren’t available, he said, oncologists and others not trained in hematology will need to cover these patients. 

Hematologist Ariela Marshall, MD, associate professor of medicine at the University of Minnesota in Minneapolis, noted in an interview that the CH shortage comes at a time when medical advances and an aging population are boosting the number of patients with noncancerous blood disorders. Older people are at greater risk for blood clots, she said. And lifespans for patients with bleeding and clotting disorders are rising thanks to effective new treatments.

“Because of our larger patient population in CH, we are going to need more classical hematologists to follow them for longer and longer periods of time,” she said. 

There’s no sign yet that newly minted physicians will take up the slack in CH. A 2019 study found that just 4.6% of 626 of hematology/oncology fellows said they planned to go into CH, also known as benign hematology, vs 67.1% who expected to treat patients with solid tumors, blood cancer, or both. The rest, 24.6%, planned to work in CH plus the two oncology fields.

 

Why Does a Shortage Exist?

“The reasons are complex, but one of the most important factors was the combining of the adult hematology and medical oncology training programs by the Accreditation Council for Graduate Medical Education in 1995,” Naik said. “After that time, the majority of fellowship training programs went from having separate programs for hematology and medical oncology to combining the training for the two specialties into one. Because most of these combined training programs resided within Cancer Centers, classical hematology training slowly became de-emphasized.”

As a result, fewer fellows ended up specializing in CH, she said. 

The field of CH also appears to suffer from a less than enticing reputation. According to a 2019 study coauthored by Marshall, surveys of thousands of hematology/oncology fellows found that “hematology, particularly benign hematology, was viewed as having poorer income potential, research funding, job availability, and job security than oncology.”

Regarding pay, Marshall said the good news is that many classical hematologists work in academia, where it’s common for pay to be “equitable across hematology/oncology divisions and based more on academic rank and other factors rather than subspecialty within hematology oncology.”

However, she noted, “this may differ at institutions where hematology and oncology are different departments. For example, centers where oncology is its own department, and hematology is part of the department of medicine.” 

As for job availability, Naik said that there’s plenty of demand. “In academics, it is clear that there are jobs available everywhere, but trainees are often worried about job prospects in private practice. While classical hematology jobs in private practice are not widely advertised, I can attest that there is no shortage of need,” she said. “Many private practices do not specifically advertise for classical hematologists because they assume that classical hematology experts are not available. But I assure you that every private practice my trainees have ever approached is always ecstatic to hire a classical hematologist.”

 

Why Are Mentors Important?

Mentorship is crucial to promoting the value of CH as a great career choice in a competitive environment, classical hematologists say. “We can motivate trainees by showing how the disease states themselves are so fascinating and how the treatments are showing great outcomes,” Nagalla said. “We can show positive results, how patient lives can be changed, and how well-respected across the system [we] are.”

As a selling point, classical hematologists like to emphasize that their field requires intensive detective work. “Let’s say a patient comes with anemia, which might have 15 different causes. You get some labs, and then you systemically rule in or rule out most of these on the differential diagnosis,” Nagalla said. “Then once you narrow it down, you get more labs. You keep going to the next step and next step, and so finally you come to a conclusion.”

As for therapy, Marshall said that “while for many cancers there are specific treatment recommendations for patients with a specific cancer type at a specific stage, there is not always a specific treatment recommendation (or a ‘right answer’) for our CH patients. Treatment planning depends strongly on a patient’s preferences, other medical conditions, and a discussion about risks [and] benefits of different treatment options such that two patients with the same condition may choose two different treatment options.”

Marshall also emphasizes to trainees that “CH is a broad field. Physicians and trainees are able to interact and collaborate with physicians in other specialties such as gastroenterology, cardiology, ob/gyn, and surgical specialties.” 

 

Does Research Support Mentorship in CH?

The 2019 study that revealed just 4.6% of fellows planned to go into CH found that “fellows who planned to enter hematology-only careers were significantly more likely to report having clinical training and mentorship experiences in hematology throughout their training relative to fellows with oncology-only or combined hematology/oncology career plans.”

Now there are more data to support mentorships. For a study published in Blood Advances in September 2024, Zoya Qureshy, MD, an internal medicine chief resident at the University of California at San Diego, and colleagues evaluated a year-long external membership program implemented by the American Society of Hematology (ASH) Medical Educators Institute. 

The program linked 35 US hematology/oncology fellows (80% female, 46% White, 35% Asian) who were interested in CH to 34 North American faculty members. The pairs were told to meet virtually once a month. 

Of 30 mentees and 23 mentors surveyed, 94% and 85%, respectively, said their pairings were good matches. Two thirds of the mentees accepted faculty positions in CH after their mentorships.

“Our study showed that external mentorship in a virtual format is feasible,” Qureshy said in an interview. “Additionally, external mentorship provided benefits such as different perspectives and the opportunity for mentorship for those who may not have it in their field of interest at their home institution.”

Qureshy added that “one strength of our mentorship program was that mentoring pairs were meticulously assigned based on shared interests and background. Many participants cited this common ground as a reason why they thought their mentoring pair was a good match.” 

There’s an important caveat: Most of the mentees weren’t new to CH. About 70% had previously worked with a mentor in the CH field, and 86% had previously conducted research in the field. 

 

What’s Next for Mentorship in CH?

The ASH Hematology-Focused Fellowship Training Program Consortium aims to mint 50 new academic hematologists by 2030 through programs at 12 institutions. “Mentorship is an exciting aspect of the program since it allows classical hematology trainees to form a network of peers nationally and also provides access to mentors across institutions,” Naik said. “And as the workforce grows, there will be more and more role models for future trainees to look up to.”

Moving forward, she said, “we hope to inspire even more institutions to adopt hematology training tracks throughout the country.”

Meanwhile, ASH’s new Classical Hematology Advancement Mentorship is taking applications for its debut 2025 program through January 9, 2025. Trainees will meet monthly with mentors both virtually and in person. Applicants must have been in their first or second year of hematology/oncology fellowship training at accredited programs in the United States as of July 15, 2024.

For some medical students and trainees who go on to become hematologists, attraction to the field happens the first time they’re engrossed in figuring out what a blood smear is telling them. Others get drawn to hematology during a rotation in residency, when they encounter patients with hemophilia or sickle cell disease.

But when it comes to turning people on to the idea of a career in classical hematology (CH), there may be no more powerful influence than a mentor who loves their job. That’s why the field is focusing so much on supporting mentors and mentees amid a stark shortage of classical hematologists.

“Mentorship is key for maintaining trainee interest in the field and for providing role models for career growth,” said Rakhi P. Naik, MD, MHS, associate professor of medicine and director of the Hematology Fellowship Track at Johns Hopkins University, Baltimore, Maryland, in an interview. “This collaboration is especially critical because there are so few trainees and so few mentors currently in the field.”

Now there’s new research backing up the power of mentorship, even when it’s only provided virtually, and a brand-new program aims to unite more mentors and mentees.

Here’s a closer look at mentor-focused efforts to attract medical students to CH.

 

How Severe Is the Shortage in CH?

Patients with conditions treated by classical hematologists are waiting months for appointments at many outpatient centers, with some being forced to wait 6 months or more, said Srikanth Nagalla, MD, chief of benign hematology at Miami Cancer Institute, Florida, in an interview.

The shortage is creating dire problems in the inpatient setting too, Nagalla said. “Serious blood disorders like heparin-induced thrombocytopenia, acute chest syndrome [a complication of sickle cell disease], and thrombotic thrombocytopenic purpura have to be diagnosed and treated in a timely manner. If not, the morbidity and mortality are really high.”

If classical hematologists aren’t available, he said, oncologists and others not trained in hematology will need to cover these patients. 

Hematologist Ariela Marshall, MD, associate professor of medicine at the University of Minnesota in Minneapolis, noted in an interview that the CH shortage comes at a time when medical advances and an aging population are boosting the number of patients with noncancerous blood disorders. Older people are at greater risk for blood clots, she said. And lifespans for patients with bleeding and clotting disorders are rising thanks to effective new treatments.

“Because of our larger patient population in CH, we are going to need more classical hematologists to follow them for longer and longer periods of time,” she said. 

There’s no sign yet that newly minted physicians will take up the slack in CH. A 2019 study found that just 4.6% of 626 of hematology/oncology fellows said they planned to go into CH, also known as benign hematology, vs 67.1% who expected to treat patients with solid tumors, blood cancer, or both. The rest, 24.6%, planned to work in CH plus the two oncology fields.

 

Why Does a Shortage Exist?

“The reasons are complex, but one of the most important factors was the combining of the adult hematology and medical oncology training programs by the Accreditation Council for Graduate Medical Education in 1995,” Naik said. “After that time, the majority of fellowship training programs went from having separate programs for hematology and medical oncology to combining the training for the two specialties into one. Because most of these combined training programs resided within Cancer Centers, classical hematology training slowly became de-emphasized.”

As a result, fewer fellows ended up specializing in CH, she said. 

The field of CH also appears to suffer from a less than enticing reputation. According to a 2019 study coauthored by Marshall, surveys of thousands of hematology/oncology fellows found that “hematology, particularly benign hematology, was viewed as having poorer income potential, research funding, job availability, and job security than oncology.”

Regarding pay, Marshall said the good news is that many classical hematologists work in academia, where it’s common for pay to be “equitable across hematology/oncology divisions and based more on academic rank and other factors rather than subspecialty within hematology oncology.”

However, she noted, “this may differ at institutions where hematology and oncology are different departments. For example, centers where oncology is its own department, and hematology is part of the department of medicine.” 

As for job availability, Naik said that there’s plenty of demand. “In academics, it is clear that there are jobs available everywhere, but trainees are often worried about job prospects in private practice. While classical hematology jobs in private practice are not widely advertised, I can attest that there is no shortage of need,” she said. “Many private practices do not specifically advertise for classical hematologists because they assume that classical hematology experts are not available. But I assure you that every private practice my trainees have ever approached is always ecstatic to hire a classical hematologist.”

 

Why Are Mentors Important?

Mentorship is crucial to promoting the value of CH as a great career choice in a competitive environment, classical hematologists say. “We can motivate trainees by showing how the disease states themselves are so fascinating and how the treatments are showing great outcomes,” Nagalla said. “We can show positive results, how patient lives can be changed, and how well-respected across the system [we] are.”

As a selling point, classical hematologists like to emphasize that their field requires intensive detective work. “Let’s say a patient comes with anemia, which might have 15 different causes. You get some labs, and then you systemically rule in or rule out most of these on the differential diagnosis,” Nagalla said. “Then once you narrow it down, you get more labs. You keep going to the next step and next step, and so finally you come to a conclusion.”

As for therapy, Marshall said that “while for many cancers there are specific treatment recommendations for patients with a specific cancer type at a specific stage, there is not always a specific treatment recommendation (or a ‘right answer’) for our CH patients. Treatment planning depends strongly on a patient’s preferences, other medical conditions, and a discussion about risks [and] benefits of different treatment options such that two patients with the same condition may choose two different treatment options.”

Marshall also emphasizes to trainees that “CH is a broad field. Physicians and trainees are able to interact and collaborate with physicians in other specialties such as gastroenterology, cardiology, ob/gyn, and surgical specialties.” 

 

Does Research Support Mentorship in CH?

The 2019 study that revealed just 4.6% of fellows planned to go into CH found that “fellows who planned to enter hematology-only careers were significantly more likely to report having clinical training and mentorship experiences in hematology throughout their training relative to fellows with oncology-only or combined hematology/oncology career plans.”

Now there are more data to support mentorships. For a study published in Blood Advances in September 2024, Zoya Qureshy, MD, an internal medicine chief resident at the University of California at San Diego, and colleagues evaluated a year-long external membership program implemented by the American Society of Hematology (ASH) Medical Educators Institute. 

The program linked 35 US hematology/oncology fellows (80% female, 46% White, 35% Asian) who were interested in CH to 34 North American faculty members. The pairs were told to meet virtually once a month. 

Of 30 mentees and 23 mentors surveyed, 94% and 85%, respectively, said their pairings were good matches. Two thirds of the mentees accepted faculty positions in CH after their mentorships.

“Our study showed that external mentorship in a virtual format is feasible,” Qureshy said in an interview. “Additionally, external mentorship provided benefits such as different perspectives and the opportunity for mentorship for those who may not have it in their field of interest at their home institution.”

Qureshy added that “one strength of our mentorship program was that mentoring pairs were meticulously assigned based on shared interests and background. Many participants cited this common ground as a reason why they thought their mentoring pair was a good match.” 

There’s an important caveat: Most of the mentees weren’t new to CH. About 70% had previously worked with a mentor in the CH field, and 86% had previously conducted research in the field.

’Tis the season for recognizing seasonal affective disorder (SAD). Just don’t expect to find SAD in diagnostic handbooks.

As a memorable term, SAD “stuck in the general public, and to some extent among health professionals,” said Scott Patten, MD, PhD, professor of psychiatry and epidemiology at the University of Calgary in Alberta, Canada. “But it’s important to emphasize that that’s not an officially recognized diagnosis by the major classifications.”

Researchers coined the term SAD 40 years ago to describe a pattern of depression that sets in during the fall or winter and remits in the spring or summer.

Clinicians are diagnosing the disorder, albeit without that exact moniker.

In the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), the condition is considered a subtype of major depression.

So, for patients who meet criteria for recurrent major depressive disorder, the specifier “with seasonal pattern” might be applied.

The subtype covers cases where depressive episodes have followed a seasonal pattern for at least 2 years. Typically, onset occurs in the fall or winter followed by remission in the spring or summer. The opposite pattern is possible but less common.

When stressors such as seasonal unemployment better explain the pattern, the seasonal specifier should not be used, according to the manual. Bipolar disorder can follow a seasonal pattern as well.

Researchers estimate SAD affects about 5% of adults in the United States. The diagnosis is more common in women than in men, and more prevalent farther from the equator.

 

One Hallmark Symptom?

DSM-5 highlights characteristic features of winter depression, including:

• Loss of energy
• Hypersomnia
• A craving for carbohydrates
• Overeating
• Weight gain

Kelly Rohan, PhD, a researcher at the University of Vermont, Burlington, who has studied SAD since the 1990s, sees one symptom as a possible hallmark for the disorder: fatigue.

“I’ve personally never met someone who met the full diagnostic criteria for the seasonal pattern that did not have fatigue as one of their symptoms,” Rohan said. “In theory, they could exist, but I have spoken to hundreds of people with seasonal depression, and I have never met them if, in fact, they do exist.”

That differs from nonseasonal depression, for which insomnia is a more common problem with sleep, Patten said.

Clinicians look for at least five symptoms of depression that cause substantial impairment and distress for at least 2 weeks, such as pervasive sadness, difficulty concentrating, low self-esteem, or loss of interest in hobbies.

An average episode of winter depression can last 5 months, however, Rohan said. “That’s a long time to be in a major depressive episode.”

 

Seeing Subsyndromal Cases

In people who do not meet criteria for major depression with a seasonal pattern, the change of seasons still can affect energy levels and mood. Some patients have “subsyndromal SAD” and may benefit from treatments that have been developed for SAD such as bright light therapy, said Paul Desan, MD, PhD, director of the Winter Depression Research Clinic at Yale School of Medicine in New Haven, Connecticut.

“Many people come to our clinic because they have seasonal changes that don’t meet the full criteria for depression, but nevertheless, they want help,” Desan said.

The 1984 paper that introduced the term SAD explored artificial bright light as a promising treatment for the condition. The researchers had heard from dozens of patients with “recurrent depressions that occur annually at the same time each year,” and bright light appeared to help alleviate their symptoms.

Subsequent trials have found the approach effective. Even in nonseasonal depression, bright light therapy may increase the likelihood of remission, a recent meta-analysis found. Light therapy also may bolster the effectiveness of antidepressant medication in nonseasonal major depressive disorder, a randomized trial has shown.

Other treatments for SAD include cognitive behavioral therapy (CBT) and bupropion XL, which is approved as a preventive medication. Other drugs for major depressive disorder may be used.

 

Quest for Biomarkers

To better understand SAD and how available treatments work, Rohan is conducting a study that examines potential biomarkers in patients treated with light therapy or CBT. She and her colleagues are examining circadian phase angle difference (how well internal clocks match daily routines) and post-illumination pupil response (how the pupil constricts after a light turns off). They also are measuring participants’ pupil responses and brain activity upon seeing words that are associated with winter or summer (like “blizzard,” “icy,” “sunshine,” and “picnics.”) 

Studies have shown treating patients to remission with CBT reduces the risk for recurrence in subsequent years, relative to other treatment approaches, Rohan said. That may be because CBT gives people tools to avoid slipping into another depressive episode.

 

Avoid Self-Diagnosis

Rohan cautions patients against self-diagnosis and treatment.

“Having a conversation with your doctor is a good starting point,” she said. “Just because you can walk into Costco and walk out with a light box doesn’t mean that you should.” 

Light therapy can have side effects, including headaches, eye strain, and making patients feel wired, and it can be a challenge to determine the right dose, Rohan said.

Desan’s clinic website provides information about available devices for light therapy for patients who are looking to try this approach, but Desan agrees clinicians — especially primary care clinicians — can play a crucial role in helping patients. In more serious cases, a mental health expert may be necessary.

To start light therapy, Desan’s clinic typically recommends patients try 30 minutes of 10,000 lux bright light — roughly the brightness of being outside on a sunny day — before 8 AM for a 4-week trial.

Still, other specific issues might explain why a patient is struggling during winter months, Patten said. For example, people might experience financial stress around the holidays or consume excessive amounts of alcohol during that time.

“It’s important for clinicians to think broadly about it,” Patten said. “It might not always be light therapy or a medication. It might be focusing on some other aspect of what is going on for them in the winter.” 

Rohan’s research is funded by the National Institute of Mental Health, and she receives royalties for a manual on treating SAD with CBT. Patten and Desan had no relevant financial disclosures.

The researchers had heard from dozens of patients with “recurrent depressions that occur annually at the same time each year,” and bright light appeared to help alleviate their symptoms.

Subsequent trials have found the approach effective. Even in nonseasonal depression, bright light therapy may increase the likelihood of remission, a recent meta-analysis found. Light therapy also may bolster the effectiveness of antidepressant medication in nonseasonal major depressive disorder, a randomized trial has shown.

Other treatments for SAD include cognitive behavioral therapy (CBT) and bupropion XL, which is approved as a preventive medication. Other drugs for major depressive disorder may be used.

 

Quest for Biomarkers

To better understand SAD and how available treatments work, Rohan is conducting a study that examines potential biomarkers in patients treated with light therapy or CBT. She and her colleagues are examining circadian phase angle difference (how well internal clocks match daily routines) and post-illumination pupil response (how the pupil constricts after a light turns off). They also are measuring participants’ pupil responses and brain activity upon seeing words that are associated with winter or summer (like “blizzard,” “icy,” “sunshine,” and “picnics.”) 

Studies have shown treating patients to remission with CBT reduces the risk for recurrence in subsequent years, relative to other treatment approaches, Rohan said. That may be because CBT gives people tools to avoid slipping into another depressive episode.

 

Avoid Self-Diagnosis

Rohan cautions patients against self-diagnosis and treatment.

“Having a conversation with your doctor is a good starting point,” she said. “Just because you can walk into Costco and walk out with a light box doesn’t mean that you should.” 

Light therapy can have side effects, including headaches, eye strain, and making patients feel wired, and it can be a challenge to determine the right dose, Rohan said.

Desan’s clinic website provides information about available devices for light therapy for patients who are looking to try this approach, but Desan agrees clinicians — especially primary care clinicians — can play a crucial role in helping patients. In more serious cases, a mental health expert may be necessary.

To start light therapy, Desan’s clinic typically recommends patients try 30 minutes of 10,000 lux bright light — roughly the brightness of being outside on a sunny day — before 8 AM for a 4-week trial.

Still, other specific issues might explain why a patient is struggling during winter months, Patten said. For example, people might experience financial stress around the holidays or consume excessive amounts of alcohol during that time.

“It’s important for clinicians to think broadly about it,” Patten said. “It might not always be light therapy or a medication. It might be focusing on some other aspect of what is going on for them in the winter.” 

Rohan’s research is funded by the National Institute of Mental Health, and she receives royalties for a manual on treating SAD with CBT. Patten and Desan had no relevant financial disclosures.

TOPLINE:

Use of the glucagon-like peptide 1 (GLP-1) receptor agonists semaglutide and liraglutide is linked to a lower risk for alcohol use disorder (AUD)–related hospitalizations, compared with traditional AUD medications, a new study suggested.

METHODOLOGY:

• Researchers conducted a nationwide cohort study from 2006 to 2023 in Sweden that included more than 220,000 individuals with AUD (mean age, 40 years; 64% men).
• Data were obtained from registers of inpatient and specialized outpatient care, sickness absence, and disability pension, with a median follow-up period of 8.8 years.
• The primary exposure measured was the use of individual GLP-1 receptor agonists — commonly used to treat type 2 diabetes and obesity — compared with nonuse.
• The secondary exposure examined was the use of medications indicated for AUD.
• The primary outcome was AUD-related hospitalization; secondary outcomes included hospitalization due to substance use disorder (SUD), somatic hospitalization, and suicide attempts.

TAKEAWAY:

• About 59% of participants experienced AUD-related hospitalization.
• Semaglutide users (n = 4321) had the lowest risk for hospitalization related to AUD (adjusted hazard ratio [aHR], 0.64; 95% CI, 0.50-0.83) and to any SUD (aHR, 0.68; 95% CI, 0.54-0.85).
• Liraglutide users (n = 2509) had the second lowest risk for both AUD-related (aHR, 0.72; 95% CI, 0.57-0.92) and SUD-related (aHR, 0.78; 95% CI, 0.64-0.97) hospitalizations.
• The use of both semaglutide (aHR, 0.78; 95% CI, 0.68-0.90) and liraglutide (aHR, 0.79; 95% CI, 0.69-0.91) was linked to a reduced risk for hospitalization because of somatic reasons but was not associated with the risk of suicide attempts.
• Traditional AUD medications showed modest effectiveness with a slightly decreased but nonsignificant risk for AUD-related hospitalization (aHR, 0.98).

IN PRACTICE:

“AUDs and SUDs are undertreated pharmacologically, despite the availability of effective treatments. However, novel treatments are also needed because existing treatments may not be suitable for all patients. Semaglutide and liraglutide may be effective in the treatment of AUD, and clinical trials are urgently needed to confirm these findings,” the investigators wrote.
