Sleep Medicine

A weighted blanket of approximately 12% body weight used at bedtime prompted the release of higher concentrations of melatonin, as measured in the saliva, compared with a lighter blanket of only about 2.4% of body weight.

This suggests that weighted blankets may help promote sleep in patients suffering from insomnia, according to the results from the small, in-laboratory crossover study.

“Melatonin is produced by the pineal gland and plays an essential role in sleep timing,” lead author Elisa Meth, PhD student, Uppsala University, Sweden, and colleagues observe.

“Using a weighted blanket increased melatonin concentration in saliva by about 30%,” Ms. Meth added in a statement.

“Future studies should investigate whether the stimulatory effect on melatonin secretion remains when using a weighted blanket over more extended periods,” the researchers observe, and caution that “it is also unclear whether the observed increase in melatonin is therapeutically relevant.”

The study was published online in the Journal of Sleep Research.

Weighted blankets are commercially available at least in some countries in Scandinavia and Germany, as examples, and in general, they are sold for therapeutic purposes. And at least one study found that weighted blankets were an effective and safe intervention for insomnia in patients with major depressive disorder, bipolar disorder, generalized anxiety disorder, and attention deficit hyperactivity disorder and led to improvements in daytime symptoms and levels of activity.
 

Study done in healthy volunteers

The study involved a total of 26 healthy volunteers, 15 men and 11 women, none of whom had any sleep issues. “The day before the first testing session, the participants visited the laboratory for an adaptation night,” the authors observe. There were two experimental test nights, one in which the weighted blanket was used and the second during which the lighter blanket was used.

On the test nights, lights were dimmed between 9 PM and 11 PM and participants used a weighted blanket covering the extremities, abdomen, and chest 1 hour before and during 8 hours of sleep. As the authors explain, the filling of the weighted blanket consisted of honed glass pearls, combined with polyester wadding, which corresponded to 12.2% of participants’ body weight.

“Saliva was collected every 20 minutes between 22:00 and 23:00,” Ms. Meth and colleagues note. Participants’ subjective sleepiness was also assessed every 20 minutes using the Karolinska Sleepiness Scale both before the hour that lights were turned off and the next morning.

“Sleep duration in each experimental night was recorded with the OURA ring,” investigators explain.

The OURA ring is a commercial multisensor wearable device that measures physiological variables indicative of sleep. Investigators focused on total sleep duration as the primary outcome measure.

On average, salivary melatonin concentrations rose by about 5.8 pg/mL between 10 PM and 11 PM (P < .001), but the average increase in salivary melatonin concentrations was greater under weighted blanket conditions at 6.6 pg/mL, compared with 5.0 pg/mL during the lighter blanket session (P = .011).

Oxytocin in turn rose by about 315 pg/mL initially, but this rise was only transient, and over time, no significant difference in oxytocin levels was observed between the two blanket conditions. There were also no differences in cortisol levels or the activity of the sympathetic nervous system between the weighted and light blanket sessions.

Importantly, as well, no significant differences were seen in the level of sleepiness between participants when either blanket was used nor was there a significant difference in total sleep duration.

“Our study cannot identify the underlying mechanism for the observed stimulatory effects of the weighted blanket on melatonin,” the investigators caution.

However, one explanation could be that the pressure exerted by the weighted blanket activates cutaneous sensory afferent nerves, carrying information to the brain. The region where the sensory information is delivered stimulates oxytocinergic neurons that can promote calm and well-being and decrease fear, stress, and pain. In addition, these neurons also connect to the pineal gland to influence the release of melatonin, the authors explain.
 

Melatonin often viewed in the wrong context

Senior author Christian Benedict, PhD, associate professor of pharmacology, Uppsala University, Sweden, explained that some people think of melatonin in the wrong context.

In point of fact, “it’s not a sleep-promoting hormone. It prepares your body and brain for the biological night ... [and] sleep coincides with the biological night, but it’s not like you take melatonin and you have a very nice uninterrupted slumber – this is not true,” he told this news organization.

He also noted that certain groups respond to melatonin better than others. For example, children with attention deficit hyperactivity disorder may have some benefit from melatonin supplements, as may the elderly who can no longer produce sufficient amounts of melatonin and for whom supplements may help promote the timing of sleep.

However, the bottom line is that, even in those who do respond to melatonin supplements, they likely do so through a placebo effect that meta-analyses have shown plays a powerful role in promoting sleep. 

Dr. Benedict also stressed that just because the body makes melatonin, itself, does not mean that melatonin supplements are necessarily “safe.”

“We know melatonin has some impact on puberty – it may delay the onset of puberty – and we know that it can also impair blood glucose, so when people are eating and have a lot of melatonin on board, the melatonin will tell the pancreas to turn off insulin production, which can give rise to hyperglycemia,” he said.

However, Dr. Benedict cautioned that weighted blankets don’t come cheap. A quick Google search brings up examples that cost upwards of $350. “MDs can say try one if you can afford these blankets, but perhaps people can use several less costly blankets,” he said. “But I definitely think if there are cheap options, why not?” he concluded.

Dr. Benedict has reported no relevant financial relationships.

Don’t like needles? Have we got a vaccine for you

Here’s a quick question: How do you turn the most annoying thing ever into something positive?

No, we’re not talking about politicians this time. No, not Elon Musk, either. Infomercials? Guess again. Humidity? Nope, even more annoying than that.

Give up? The most annoying thing ever is mosquitoes. This time, however, NPR reports that mosquitoes have been used to deliver a vaccine for the very disease they’ve been transmitting to their human food sources all these years.

In a recent proof-of-concept trial, investigators used CRISPR technology to genetically modify malaria-causing Plasmodium falciparum sporozoites, which just happen to live in the salivary glands of Anopheles mosquitoes. And since the Plasmodium parasites are already in the mosquitoes, it made sense to use the buzzy little critters as the delivery device for the vaccine.

More sense than a syringe, you ask? Have you ever tried to poke a syringe into the salivary gland of a mosquito? No, we thought not. Well, we can tell you from experience that it’s really, really hard. Never mind how we know. We just do.

The 14 study volunteers – who were paid $4,100 for their participation – were first exposed to hundreds of mosquitoes carrying the altered Plasmodium parasites. Then, to test the vaccine, they were exposed to mosquitoes that had actual, malaria-carrying Plasmodium. Half of the subjects got malaria, so the vaccine was only 50% effective, meaning there’s still work to do.

Meanwhile, the scientists here at LOTMEco are all over this mosquito-delivery business, working on a vaccine to prevent Elon Musk. Plan B involves some sort of really big swatter.
 

Climate change: Sleeping your life away

It’s no secret that climate change is raising the temperature on everything. You may think you’re getting relief when the sun goes down, but in some places it’s still hot. A new survey conducted in central Japan shows how bad it can be and how higher nighttime temperatures can have a serious impact on people’s health.

Public Domain Vectors

That online survey, the Sleep Quality Index for Daily Sleep, enabled the investigators to correlate sleep quality with daily temperature for 1,284 adults in 2011 and 2012 who completed the survey over 10 days.

Not only was there a significant difference in sleep disturbance among younger men (higher) versus older men, but the prevalence of sleep disturbance went up when the daytime temperature was above 24.8° C. They also found that disability-adjusted life-years (DALYs), which measure time lost through premature death and time lived in certain conditions that put one’s health at risk, were 81.8 years for the city of Nagoya (population, 2.2 million) in 2012.

The damage to health from sleep disorders caused by daily temperatures higher than 25° C “is comparable to that of heatstroke and must be addressed,” lead author Tomohiko Ihara of the University of Tokyo said in a written statement.

The researchers hope that this information will help sway legislators to consider the impact of higher nighttime temperatures and that it can be used to provide guidance for better sleep. The solution for now? Sleep with the air conditioner on. Your energy bill might increase, but just think about those DALYs. If using the AC lowers DALYs and increases time lived, then we say it’s worth it.
 

Maybe it would have been a dragon WITH cancer

If you ask a random person on the street to tell you all they know about the country of Wales, they’ll probably mention two things: One, the contorted collection of jumbled-up letters that is the Welsh language (looking at you, Llanfairpwllgwyngyll­gogery­chwyrn­drobwll­llan­tysilio­gogo­goch) and, two, the association with dragons. The Welsh flag even has a dragon on it.

evakocsan/Pixnio

With that in mind, take a guess as to what sort of statue art dealer Simon Wingett wanted to build in the Welsh town of Wrexham. No, not a monument to the second-longest place name in the world. Try again. His dragon would not be some piddly little thing either; he wanted a virtual kaiju overlooking the town, with the whole statue to stand about 60 meters high. That’s taller than the original 1954 Godzilla.

Artistic masterpieces may sell for frankly insane prices, but art dealers themselves are not the wealthiest of individuals, so Mr. Wingett needed money to fund his dragon-based dream. Lucky for him, he also happened to be the manager of a cancer charity – initially set up by Mr. Wingett’s father, who had throat cancer – which nominally aimed to provide equipment and resources to cancer patients in the Wrexham area.

Yes, this is going precisely where you think it’s going. From 2011 to 2018, when the charity closed, Mr. Wingett used the charity’s donations to fund his dragon statue – which never actually got built, by the way – to the tune of over 400,000 pounds. Of course, Mr. Wingett came under scrutiny when people started to notice that his cancer charity hadn’t actually done anything charitable since 2011, and he was recently banned by the Welsh High Court from serving as trustee of any charity for 10 years. Oh no, tragedy and horror! Truly a punishment worse than death itself.

Okay fine, he also has to pay back 117,000 pounds to actual legitimate cancer charities. The astute mathematicians out there may notice that 117,000 is a lot less than 400,000. But it’s just as the old saying goes: One-quarter of crime doesn’t pay. You can keep three-quarters of it, though, that’s completely fine.

Editor's Note: We periodically publish patient viewpoints on specific issues of interest to our audience.

I woke up in a strange bedroom with 24 electrodes glued all over my body and a plastic mask attached to a hose covering my face.

The lab technician who watched me all night via video feed told me that I had “wicked sleep apnea” and that it was “central sleep apnea” – a type that originates in the brain and fails to tell the muscles to inhale.

As a journalist– and one terrified by the diagnosis – I set out to do my own research. After a few weeks of sleuthing and interviewing experts, I reached two important conclusions.

First, I had moderate apnea, if that, and it could be treated without the elaborate machines, mouthpieces, or other devices that specialists who had consulted on my care were talking about.

Second, the American health care system has joined with commercial partners to define a medical condition – in this case, sleep apnea – in a way that allows both parties to generate revenue from a multitude of pricey diagnostic studies, equipment sales, and questionable treatments. I was on a conveyor belt.

It all began with a desire for answers: I had been feeling drowsy during the day, and my wife told me I snored. Both can mean obstructive sleep apnea. With obstructive sleep apnea, the mouth and throat relax when a person is unconscious, sometimes blocking or narrowing the airway. That interrupts breathing, as well as sleep. Without treatment, the resulting disruption in oxygen flow might increase the risk of developing certain cardiovascular diseases.

So I contacted a sleep-treatment center, and doctors gave me an at-home test ($365). Two weeks later, they told me I had “high-moderate” sleep apnea and needed to acquire a continuous positive airway pressure (CPAP) machine, at a cost of about $600.

Though I had hoped to get the equipment and adjust the settings to see what worked best, my doctors said I had to come to the sleep lab for an overnight test ($1,900) to have them “titrate” the optimal CPAP air pressure.

“How do you treat central sleep apnea?” I worriedly asked the technician after that first overnight stay. She said something about an adaptive servo-ventilation machine ($4,000). And one pricey lab sleepover wasn’t enough, she said. I needed to come back for another.

(Most procedures and devices mentioned in this article were covered or would have been covered by insurance – in my case, Medicare, plus a supplemental plan. Unnecessary care is a big reason Americans’ insurance costs – premiums, copays, and deductibles – tend to rise year after year.)

As a journalist who spent years covering the business of health care, I found there was more motivating my expensive testing cascade than concerns about my health.

The American Academy of Sleep Medicine, a nonprofit based near Chicago, decides what is sleep apnea and how to treat it. Working with sleep societies around the world, it publishes the International Classification of Sleep Disorders, relied on by doctors everywhere to diagnose and categorize disease.

But behind that effort lie considerable conflicts of interest. Like so much of U.S. health care, sleep medicine turns out to be a thriving industry. AASM finances its operations in part with payments from CPAP machine manufacturers and other companies that stand to profit from expensive treatments and expansive definitions of apnea and other sleep disorders.

Zoll Itamar, which makes the at-home testing device I used, as well as implantable nerve-stimulation hardware for central sleep apnea, is a $60,000, “platinum” partner in AASM’s Industry Engagement Program. So is Avadel Pharmaceuticals, which is testing a drug to treat narcolepsy, characterized by intense daytime sleepiness.

Other sponsors include the maker of an anti-insomnia drug; another company with a narcolepsy drug; Fisher & Paykel Healthcare, which makes CPAP machines and masks; and Inspire Medical Systems, maker of a heavily advertised surgical implant, costing tens of thousands of dollars, to treat apnea.

Corporate sponsors for Sleep 2022, a convention AASM put on in Charlotte, N.C., with other professional societies, included many of those companies, plus Philips Respironics and ResMed, two of the biggest CPAP machine makers.

In a statement, AASM spokesperson Jennifer Gibson said a conflict-of-interest policy and a noninterference pledge from industry funders protect the integrity of the academy’s work. Industry donations account for about $170,000 of AASM’s annual revenue of about $15 million. Other revenue comes from educational materials and membership and accreditation fees.

Here’s what else I found. Almost everybody breathes irregularly sometime at night, especially during REM sleep, characterized by rapid eye movement and dreams. Blood oxygen levels also fluctuate slightly.

But recent European studies have shown that standards under the International Classification of Sleep Disorders would doom huge portions of the general population to a sleep apnea diagnosis – whether or not people had complaints of daytime tiredness or other sleep problems.

A study in Lausanne, Switzerland, showed that 50% of local men and 23% of the women 40 or older were positive for sleep apnea under such criteria.

Such rates of disease are “extraordinarily high,” “astronomical,” and “implausible,” Dirk Pevernagie, PhD, a scientist at Ghent (Belgium) University Hospital, wrote with colleagues 2 years ago in a comprehensive study in the Journal of Sleep Research.

“Right now, there is no real evidence for the criteria that have been put forward to diagnose obstructive sleep apnea and rate its severity,” he said in an interview.

Likewise, 19% of middle-aged subjects in a 2016 Icelandic study appeared to have moderate to severe “apnea” under one definition in the International Classification of Sleep Disorders even though many reported no drowsiness.

“Most of them were really surprised,” said Erna Sif Arnardóttir, who led the study and is running a large European program to refine detection and treatment of apnea.

Nevertheless, the official AASM journal recommends extremely broad screening for sleep apnea, looking for patients who have what it defines as illness. Everybody 18 and older should be screened every year for apnea if they have diabetes, obesity, untreated high blood pressure, or heart disease – even if they have never complained about sleep problems, the group says.

AASM “continually evaluates the definitions, criteria and recommendations used in the identification of sleep apnea and other sleep disorders,” Ms. Gibson said in the statement. Meanwhile, routine screening by primary care doctors “is a simple way” of gauging whether a high-risk patient may have obstructive sleep apnea, the statement said.

The U.S. Preventive Services Task Force, an authoritative body that reviews the effectiveness of preventive care, takes a conservative view, more like that of the European researchers, concluding there is “insufficient” evidence to support widespread screening among patients with no symptoms.

Many insurers refuse to pay for CPAP machines and other treatments prescribed for people at the outer edges of the AASM’s apnea definition. But AASM is pressuring them to come around.

After all my reporting, I concluded that my apnea is real, though moderate. My alarming reading in the overnight lab – diagnosed quickly as central sleep apnea – was a byproduct of the testing machinery itself. That’s a well-described phenomenon that occurs in 5% to 15% of patients.

And when I looked closely at the results of my at-home diagnostic test, I had an epiphany: My overall score was 26 breathing interruptions and blood-oxygen level declines, on average, per hour – enough to put me in the “high-moderate” category for apnea. But when I looked at the data sorted according to sleeping positions, I saw that I scored much better when I slept on my side: only 10 interruptions in an hour.

So I did a little experiment: I bought a $25 pulse oximeter with a smartphone app that records oxygen dips and breathing interruptions. When I slept on my side, there were hardly any.

Now I sleep on my side. I snore less. I wake up refreshed. I’m not daytime drowsy.

None of my specialists mentioned turning on to my side – known in medical parlance as “positional therapy” – though the intervention is recognized as effective by many researchers. Sleeping on one’s back contributes to snoring and blockages, especially as people age and the muscles in the throat become looser.

“Positional patients ... can sleep in the lateral position and sleep quite well,” said Arie Oksenberg, PhD, a sleep researcher formerly at Loewenstein Hospital in Ra’anana, Israel.

But it’s not easy to find this in the official AASM treatment guidelines, which instead go right to the money-making options like CPAP machines, surgery, central apnea, and mouth appliances.

Dealing with apnea by shifting slightly in bed gets little more than a couple of paragraphs in AASM’s guideline on “other” treatments and a little box on a long and complex decision chart.

A third or more of patients wear CPAPs only a few hours a night or stop using them. It turns out people don’t like machines in their beds.

“Positional therapy is an effective treatment option for some patients,” said Ms. Gibson. But she said there are concerns about whether patients will sleep on their sides long term and whether trying to stay in one position might cause sleep interruptions itself.

It’s true that side-sleeping doesn’t help everybody. And it often takes practice. (Some people tape a tennis ball to their pajamas to keep them off their backs.) Even conservative sleep doctors say CPAP machines are the best solution for many patients.

But there is a largely overlooked alternative.

“Are we missing a simple treatment for most adult sleep apnea patients?” was the name of a 2013 paper that Dr. Oksenberg and a colleague wrote about positional therapy.

In my case, the answer was “yes.”

I woke up in a strange bedroom with 24 electrodes glued all over my body and a plastic mask attached to a hose covering my face.

The lab technician who watched me all night via video feed told me that I had “wicked sleep apnea” and that it was “central sleep apnea” – a type that originates in the brain and fails to tell the muscles to inhale.

The American Academy of Sleep Medicine has issued a health advisory encouraging parents to talk to a health care professional before giving melatonin or any supplement to children.

“While melatonin can be useful in treating certain sleep-wake disorders, like jet lag, there is much less evidence it can help healthy children or adults fall asleep faster,” Muhammad Adeel Rishi, MD, MBBS, vice chair of the AASM public safety committee, said in a news release.
 

Spike in poisoning calls

Research previously published in JAMA suggests that the use of melatonin has increased over the past 2 decades among people of all ages.

With this increased use has come a spike in reports of melatonin overdose, calls to poison control centers, and related emergency department visits for children.

Federal data show that the number of U.S. children who unintentionally ingested melatonin supplements jumped 530% from 2012 to 2021.

More than 4,000 of the reported ingestions led to a hospital stay, and 287 children required intensive care.

The AASM notes that next to multivitamins, melatonin is the second most popular “natural” product parents give to their children.

Melatonin is widely available over the counter. It’s marketed as a sleep aid, but there is little evidence that taking it as a supplement is effective in treating insomnia in healthy children, the AASM cautions.

Because it is regulated by the U.S. Food and Drug Administration as a dietary supplement, melatonin receives less oversight. Research shows that the melatonin content in supplements can vary widely, the AASM points out.

In one study, amounts of melatonin ranged from less than one-half to more than four times the amounts stated on the labels. The greatest variability in melatonin content was in chewable tablets, which are most likely to be used for children.

“The availability of melatonin as gummies or chewable tablets makes it more tempting to give to children and more likely for them to overdose,” said Dr. Rishi, a pulmonology, sleep medicine, and critical care specialist at Indiana University Health Physicians, Indianapolis.

“Parents should talk directly with their child’s health care professional before giving their children melatonin products,” he added.
 

Keep out of reach

The AASM advises that melatonin be managed as any other medication and that it be kept out of reach of children.

Before giving melatonin or any supplement to their children, parents should discuss this decision with a pediatric health care professional.

If use of melatonin is warranted, health care professionals can recommend the appropriate dose and timing in addressing the sleep problem, and they can ensure that the melatonin product that is being used has a USP verified mark.

“Instead of turning to melatonin, parents should encourage children to develop good sleep habits, like setting a regular bedtime and wake time, having a bedtime routine, and limiting screen time as bedtime approaches,” Dr. Rishi said.

Melatonin is widely available over the counter. It’s marketed as a sleep aid, but there is little evidence that taking it as a supplement is effective in treating insomnia in healthy children, the AASM cautions.

Because it is regulated by the U.S. Food and Drug Administration as a dietary supplement, melatonin receives less oversight. Research shows that the melatonin content in supplements can vary widely, the AASM points out.

In one study, amounts of melatonin ranged from less than one-half to more than four times the amounts stated on the labels. The greatest variability in melatonin content was in chewable tablets, which are most likely to be used for children.

“The availability of melatonin as gummies or chewable tablets makes it more tempting to give to children and more likely for them to overdose,” said Dr. Rishi, a pulmonology, sleep medicine, and critical care specialist at Indiana University Health Physicians, Indianapolis.

“Parents should talk directly with their child’s health care professional before giving their children melatonin products,” he added.
 

Keep out of reach

The AASM advises that melatonin be managed as any other medication and that it be kept out of reach of children.

Before giving melatonin or any supplement to their children, parents should discuss this decision with a pediatric health care professional.

If use of melatonin is warranted, health care professionals can recommend the appropriate dose and timing in addressing the sleep problem, and they can ensure that the melatonin product that is being used has a USP verified mark.

“Instead of turning to melatonin, parents should encourage children to develop good sleep habits, like setting a regular bedtime and wake time, having a bedtime routine, and limiting screen time as bedtime approaches,” Dr. Rishi said.

Patients with inflammatory bowel disease (IBD) are 70% more likely to use benzodiazepines and “Z-drugs” than are the general population, a large study from Canada suggests. 

Mood/anxiety disorders and sleep disorders are common in patients with IBD, but few studies have looked at use of benzodiazepines and Z-drugs (such as zolpidem, zaleplon, and eszopiclone) in this patient population.

The results are “concerning, and especially as the IBD population ages, these drugs are associated with health risks, including something as simple as falls,” first author Charles Bernstein, MD, of the IBD clinical and research centre, University of Manitoba, Winnipeg, told this news organization.

“Clinicians need to find better strategies to deal with anxiety disorders and sleep disorders in the IBD population,” Dr. Bernstein said.

The study was published online in the American Journal of Gastroenterology.
 

High burden of use

Using administrative data from Manitoba, Dr. Bernstein and colleagues identified 5,741 patients with IBD (2,381 with Crohn’s disease and 3,360 with ulcerative colitis) and matched them (1:5) to 28,661 population controls without IBD.

Over a 20-year period (1997-2017), there was a “high burden” of benzodiazepine and Z-drug use in the IBD population. In 2017, roughly 20% of Manitobans with IBD were using benzodiazepines, and 20% were using Z-drugs, the study team reports.

The benzodiazepine use rate (per 1,000) was 28.06 in the IBD cohort vs. 16.83 in the non-IBD population (adjusted rate ratio, 1.67). The use rate for Z-drugs was 21.07 in the IBD cohort vs. 11.26 in the non-IBD population (adjusted RR, 1.87).

Benzodiazepine use declined from 1997 to 2016, but it remained at least 50% higher in patients with IBD than in the general population over this period, the researchers found. The rate of Z-drug use also was higher in the IBD population than in the general population but remained stable over the 20-year study period.

Regardless of age, men and women had similarly high use rates for benzodiazepines, Z-drugs, and joint use of benzodiazepines and Z-drugs. The highest incidence rates for joint benzodiazepine and Z-drug use were in young adults (age 18-44 years), and these rates were similar among men and women.

Patients with IBD and a mood/anxiety disorder also were more likely to use benzodiazepines and Z-drugs and to be continuous users than were those without a mood/anxiety disorder.
 

Mental health and IBD go hand in hand

“The results are not very surprising, but they highlight the importance of mental health and mood disturbances in patients with IBD,” Ashwin Ananthakrishnan, MBBS, MPH, with Massachusetts General Hospital and Harvard Medical School in Boston, who wasn’t involved in the study, told this news organization.

“It is important for treating physicians to be aware of the important mental health implications of IBD diagnosis and disease activity, to screen patients for these disturbances, and to institute early effective interventions,” Dr. Ananthakrishnan said.

Also offering perspective, Laurie Keefer, PhD, academic health psychologist and director of psychobehavioral research within the division of gastroenterology, Mount Sinai Health System, New York, said that she is “concerned but not surprised” by the results of this study.

“One in three patients with IBD meets criteria for an anxiety disorder,” Dr. Keefer told this news organization.

And with the ongoing mental health crisis and shortage of mental health providers, “gastroenterologists are, unfortunately, in the position where they may have to manage these issues,” she said.

Dr. Keefer noted that when patients are first diagnosed with IBD, they will likely be on prednisone, and “an antidote” for the side effects of prednisone are benzodiazepines and sleeping medications because prednisone itself causes insomnia. “However, that’s really just a band-aid,” she said.

A major concern, said Dr. Keefer, is that young men and women who are diagnosed with IBD in their 20s may start using these drugs and become reliant on them.

“People do build up a tolerance to these drugs, so they need more and more to receive the same effect,” she said.

A better approach is to figure out why patients are so anxious and teach them skills to manage their anxiety and sleep problems so that they’re not dependent on these drugs, Dr. Keefer said.

“There are behavioral strategies that can help. These are harder to do, and they’re not a quick fix. However, they are skills you can learn in your 20s and so when you have an IBD flare at 50, you have the skills to deal with it,” she said.

“We just have to be a little more proactive in really encouraging patients to learn disease management skills,” Dr. Keefer added.

The study was funded by the Canadian Institutes of Health Research and Crohn’s and Colitis Canada. Dr. Bernstein has disclosed relationships with AbbVie Canada, Amgen Canada, Bristol-Myers Squibb Canada, Roche Canada, Janssen Canada, Sandoz Canada, Takeda and Takeda Canada, Pfizer Canada, Mylan Pharmaceuticals, and Medtronic Canada. Dr. Ananthakrishnan and Dr. Keefer report no relevant financial relationships.

People who stay up late may be at greater risk for type 2 diabetes and cardiovascular disease than those who turn in early, according to new research.

In the study involving 51 people, night owls metabolized fat less efficiently, showed less insulin sensitivity, and demonstrated lower physical fitness than early birds, lead author Steven K. Malin, PhD, of Rutgers University, New Brunswick, N.J., and colleagues reported.

Prior publications have suggested that night owls, formally known as “late chronotypes,” have an increased risk of obesity, type 2 diabetes, and cardiovascular disease, Dr. Malin said in an interview. But no previous research involved the gold-standard measurement tools used in this study, including euglycemic clamp and indirect calorimetry to quantify fat metabolism.

Dr. Malin also noted that this is the first study of its kind to characterize metabolism during both rest and exercise.

The study, published in Experimental Physiology, involved 24 early birds and 27 night owls classified by the Morning-Eveningness Questionnaire. All participants were sedentary, reporting less than one hour of structured exercise per week, and had metabolic syndrome according to Adult Treatment Panel III report criteria. Groups were otherwise demographically similar, with average ages in each group of approximately 54-55 years.

Compared with night owls, early birds were more physically active during the morning into midday. During exercise, they metabolized more fat and demonstrated greater physical fitness based on VO_2max readings. At rest, early birds also came out ahead – they had higher fat oxidation and non–oxidative glucose disposal, suggesting more sensitivity to insulin.

“Collectively, this work highlights and supports chronotype as a potential risk factor related to type 2 diabetes and cardiovascular disease risk,” the investigators concluded.
 

Night owls have less metabolic control

Jed Friedman, PhD, director of OU Health Harold Hamm Diabetes Center at the University of Oklahoma Health Sciences Center, Oklahoma City, praised the study for the size of the groups the researchers compared with each other and how well matched those groups were, as well as the “state-of-the-art” measurement tools employed.

The findings show that night owls have “less metabolic control,” Dr. Friedman said in an interview.

“That’s a term that’s frequently invoked in [regard to] prediabetes,” he said. “Blood sugar goes up, because when you’re eating a high carbohydrate diet, your cells aren’t metabolizing sugar properly. That tends to raise your risk for a lot of diseases.”

Dr. Friedman added that the findings align with those of previous studies that have linked less sleep with changes in brain biology, and therefore behavior, especially in dietary choices.

“When you’re tired, the mechanisms for appetite control go haywire,” Dr. Friedman explained. “The evidence suggests that sugar is the primary driver for what people eat when they’re tired. That obviously has implications for diabetes and metabolic syndrome. So sleeping more really can help you control cravings.”

Dr. Friedman also noted that people who are tired tend to engage in less physical activity, further increasing their risk of metabolic issues. To control this risk, he advised people to return to their circadian rhythms, which could mean forgetting the midnight snack.

“Having a daily pattern that’s in sync with chronicity, or these daily rhythms, is associated with greater health,” Dr. Friedman said. “We’re not really made to eat at night. I think this [study] kind of reinforces that.”
 

Can a night owl become an early bird?

When asked if a person’s natural circadian rhythm can be later, Dr. Malin responded that chronotypes may be dictated by genetics and age, as well as external drivers like work schedule. For these reasons, it’s “tricky” to answer whether night owls can turn into early birds and reap the potential health benefits of making that shift.

“Given that so many life factors can influence what our routine entails, it’s hard to know if we [can] truly change our chronotype or if rather we [can] learn to manage,” Dr. Malin said. “In either case, there is some work that suggests people can adopt earlier bedtimes and waketimes through practical recommendations.”

Specifically, he suggested increasing physical activity during the day, and adjusting bedtimes gradually by 15-minute increments.

“Go to bed 15 minutes earlier then wake up 15 minutes earlier,” Dr. Malin said. “In time, and depending on how things are going, this can expand to another 15-minute window. Then, during the earlier time waking up, a person can engage in light physical activity to help with promoting general fitness. If they can get outside with sunlight, that would be great too, as the natural sunlight would provide cues to the circadian system to adjust.”

The study was supported by the National Institutes of Health. The investigators and Dr. Friedman disclosed no conflicts of interest.

Add unprovoked venous thromboembolic events to the list of potential consequences of severe obstructive sleep apnea.

That conclusion comes from a study showing that patients with obstructive sleep apnea (OSA) who had the longest nocturnal hypoxemia episodes had a twofold risk for venous thromboembolic events.

The association between nocturnal hypoxemia and VTE was strongest among patients who did not use continuous positive airway pressure (CPAP) systems, reported Wojciech Trzepizur, MD, of Angers University Hospital, France.

Previous studies have suggested links between OSA and both cancer and cognitive decline, but this is the first study to investigate the association between OSA and the incidence of unprovoked VTE, he reported in an oral abstract session at the annual congress of the European Respiratory Society.

“We found that those who spent more than 6% of their nighttime with levels of oxygen in their blood below 90% of normal had an almost twofold risk of developing VTEs compared to patients without oxygen deprivation,” he said.

Dr. Trzepizur and colleagues conducted a retrospective study linking cohort data to an administrative health database. They identified unprovoked VTE in patients with a suspicion for OSA and no previous VTE.

They created Cox proportional hazard models to assess the association of unprovoked VTE with apnea hypopnea index (AHI) measures and nocturnal hypoxemia markers, including the time patients spent below 90% oxygen saturation (T90), oxygen desaturation index (ODI), and hypoxic burden, defined as the total area under the respiratory event-related desaturation curve.

They found that after a median follow-up of 6.3 years, 104 out of 7,355 patients had an unprovoked VTE. In an unadjusted hazard model, there were significant associations between VTE and T90, as well as with hypoxic burden, but not with either AHI or ODI.

However, in an analysis adjusted for age, gender, body mass index, alcohol intake, hypertension, depression, history of cardiovascular disease, statin use, type of sleep study, study site, and CPAP adherence, the investigators found that only T90 remained a significant independent predictor of VTE, with a hazard ratio of 1.06, P = .02.

The association between T90 and VTE strengthened as the time spent below 90% saturation increased. Patients in the highest tercile, who spent more than 6% of the time undersaturated, had an HR for VTE of 1.95 (P = .02), compared with patients with a T90 less than 1%.

There were no significant differences in VTE risk between patients who used CPAP for more than 4 hours per night and those who either used the devices for less than 4 hours or refused CPAP.

“We see that T90 seems to be a strong parameter,” said session comoderator Raphael Heinzer, MD, MPH, of Lausanne University Hospital, Switzerland.

Dr. Heinzer’s comoderator, Silke Ryan, MD, of University College Dublin, pointed out that although T90 was the main predictor of responses, Dr. Trzepizur and colleagues did not control for other pulmonary diseases.

“Obviously, there could be an influence of other hypoxic-related diseases,” she said, and recommended controlling for this in future studies.

Winfried Randerath, MD, of the Bethanien Hospital at the University of Cologne, Germany, head of the ERS specialist group on sleep disordered breathing, said that this study and others presented at the meeting “show worrying associations between obstructive sleep apnea and important diseases that affect survival and quality of life.

“While they cannot prove that OSA causes any of these health problems, people should be made aware of these links and should try to make lifestyle changes in order to reduce their risk of OSA, for instance, by maintaining a healthy weight. However, if OSA is suspected, definite diagnosis and treatment should be initiated. We look forward to further research that may help to clarify whether OSA may be causing some of the health problems seen in these studies,” said Dr. Randerath, who was not involved with the study.

The study was supported by a grant from Institut de Recherche en Santé Respiratoire des Pays de la Loire (IRSR), Beaucouzé, France. Dr. Trzepizur, Dr. Heinzer, Dr. Ryan and Dr. Randerath reported no relevant financial relationships.

Add unprovoked venous thromboembolic events to the list of potential consequences of severe obstructive sleep apnea.

That conclusion comes from a study showing that patients with obstructive sleep apnea (OSA) who had the longest nocturnal hypoxemia episodes had a twofold risk for venous thromboembolic events.

The association between nocturnal hypoxemia and VTE was strongest among patients who did not use continuous positive airway pressure (CPAP) systems, reported Wojciech Trzepizur, MD, of Angers University Hospital, France.

Previous studies have suggested links between OSA and both cancer and cognitive decline, but this is the first study to investigate the association between OSA and the incidence of unprovoked VTE, he reported in an oral abstract session at the annual congress of the European Respiratory Society.

“We found that those who spent more than 6% of their nighttime with levels of oxygen in their blood below 90% of normal had an almost twofold risk of developing VTEs compared to patients without oxygen deprivation,” he said.

Dr. Trzepizur and colleagues conducted a retrospective study linking cohort data to an administrative health database. They identified unprovoked VTE in patients with a suspicion for OSA and no previous VTE.

They created Cox proportional hazard models to assess the association of unprovoked VTE with apnea hypopnea index (AHI) measures and nocturnal hypoxemia markers, including the time patients spent below 90% oxygen saturation (T90), oxygen desaturation index (ODI), and hypoxic burden, defined as the total area under the respiratory event-related desaturation curve.

They found that after a median follow-up of 6.3 years, 104 out of 7,355 patients had an unprovoked VTE. In an unadjusted hazard model, there were significant associations between VTE and T90, as well as with hypoxic burden, but not with either AHI or ODI.

However, in an analysis adjusted for age, gender, body mass index, alcohol intake, hypertension, depression, history of cardiovascular disease, statin use, type of sleep study, study site, and CPAP adherence, the investigators found that only T90 remained a significant independent predictor of VTE, with a hazard ratio of 1.06, P = .02.

The association between T90 and VTE strengthened as the time spent below 90% saturation increased. Patients in the highest tercile, who spent more than 6% of the time undersaturated, had an HR for VTE of 1.95 (P = .02), compared with patients with a T90 less than 1%.

There were no significant differences in VTE risk between patients who used CPAP for more than 4 hours per night and those who either used the devices for less than 4 hours or refused CPAP.

Both yoga and cognitive-behavioral therapy (CBT) provide meaningful improvements in worry, anxiety, and insomnia in older adults that last even 6 months after discontinuing treatment, new research suggests.

The study is the first to compare the long-term effects from the two interventions; and the results offer clinicians and patients two effective choices for reducing worry and anxiety, researchers noted.

“Anxiety can be a really big problem for older adults,” lead investigator Suzanne Danhauer, PhD, professor of social sciences and health policy at Wake Forest University, Winston-Salem, N.C., said in an interview.

“So to find something they can do that lasts ... and has some enduring impact on their quality of life and their mental health, and they’re both nonpharmacologic treatments, I think for a lot of older people that’s really attractive,” Dr. Danhauer said.

The findings are published in the September issue of the American Journal of Geriatric Psychiatry.
 

Long-term benefits

The two-stage randomized preference trial included 500 community-dwelling individuals over age 60 who scored 26 or above on the Penn State Worry Questionnaire–Abbreviated (PSWQ-A), indicating heightened anxiety and worry.

Half the group took part in a randomized, controlled trial comparing CBT (n = 125) with yoga (n = 125). The other half participated in a preference trial where they were allowed to choose between CBT (n = 120) and yoga (n = 130).

Participants completed 20 yoga sessions over 10 weeks or 10 weekly CBT calls between May 2017 and November 2018.

Measures used included the PSWQ-A, the Insomnia Severity Index (ISI), the Patient Reported Outcomes Measurement Information System (PROMIS) Short Form v1.0 – Anxiety 8a, and the PROMIS-29 to assess depression, fatigue, physical function, social participation, and pain.

In 2020, the researchers published results at 11 weeks showing improvements from baseline in all areas. The scores for anxiety and worry were similar between the CBT and yoga groups, but CBT yielded significantly higher improvement in insomnia.

At 37 weeks, about 6 months after the interventions had ended, the investigators found even greater improvements from baseline in all areas measured – except physical function.

However, at that point, there were no significant differences between the two interventions in either the randomized controlled trial or the preference trial. There were also no differences in the results between the two trial designs.

“There were some little differences, but by and large we found both interventions to be efficacious,” Dr. Danhauer said. “This gives clinicians [the] choice to be able to say, ‘you can try either one of these and they’re probably going to help.’ ”
 

Beyond statistically significant

The researchers also found the improvements were not just statistically significant, but were also clinically meaningful for worry, anxiety, and insomnia.

Meaningful changes were defined as a decrease of at least 5.5 points on the PSWQ-A for worry, a decrease of at least 3 points on the PROMIS Anxiety scale for anxiety, and a decrease of at least 6 points in the ISI for insomnia.

At long-term follow-up, the majority of participants in both the CBT and yoga arms of the randomized, controlled trial demonstrated meaningful change in worry (85.7% and 77.6%, respectively), anxiety (82.1% and 80.8%), and insomnia (52.8% and 44.3%).

The majority of participants also reported meaningful improvements in generalized anxiety symptoms, depressive symptoms, and fatigue, but not for physical function, pain interference, or pain intensity.

“That’s the part to me that’s particularly notable. The improvements weren’t just statistically significant, they were clinically meaningful as well,” Dr. Danhauer said.

“When it comes right down to people’s lives, they want differences they can feel and see and not just what a P value looks like,” she added.
 

Real-world impact

In an accompanying editorial, Carmen Andreescu, MD, associate professor of psychiatry at the University of Pittsburgh, agreed that the results have “real-world impact.”

“Clinicians can direct their patients toward interventions that may be beneficial, consolidate the results over time and avoid fueling the well-trained worry cognitive loop with concerns related to potential side effects,” Dr. Andreescu wrote.

She adds that interventions such as these “may increase accessibility and provide relief for the immediate suffering of our patients.”

The study was funded by the Patient-Centered Outcomes Research Institute Program. Dr. Danhauer and Dr. Andreescu reported no relevant financial relationships.

Difficulty achieving regular restorative sleep is a common symptom of many psychiatric illnesses and can pose a pharmaceutical challenge, particularly for patients who have contra­indications to benzodiazepines or sedative-hypnotics. Melatonin is commonly used to treat insomnia and circadian rhythm disorders in hospitalized patients because it is largely considered safe, nonhabit forming, unlikely to interact with other medications, and possibly protective against delirium.¹ We support its short-term use in patients with sleep disruption, even if they do not meet the diagnostic criteria for insomnia or a circadian rhythm sleep-wake disorder. However, this use should be guided by consideration of the known physiological actions of melatonin, and not by an assumption that it acts as a simple sedative-hypnotic.

How melatonin works

Melatonin is an endogenous neurohormone involved in circadian rhythm regulation (sleep/wake regulation), a fundamental process in the functioning of the CNS and in the development of psychiatric disorders.² Melatonin is commonly described as a sleep-promoting neurotransmitter, but it is more accurately described as a “darkness hormone.”³ With an onset at dusk and offset at sunrise, melatonin is the signal for biological night, not the signal for sleep. Melanopsin-containing retina neurons sensitive to blue light sense the diminishing light of the evening and communicate this cue to the brain’s master clock in the suprachiasmatic nucleus (SCN) of the hypothalamus (via the retinohypothalamic pathway). The SCN then releases its inhibition on the pineal gland, allowing it to release melatonin into the bloodstream and CSF. The timing of this release is known as the dim-light melatonin onset (DLMO).

Selecting the optimal timing and dose

Studies in laboratory and home settings have consistently shown that the DLMO precedes the onset of sleep by approximately 2 to 4 hours.⁴ Thus, we recommend scheduling melatonin administration for 2 to 4 hours before the intended bedtime.

Lower doses better replicate physiological levels of melatonin. A lower dose is also less likely to lead to a compromise of the entrainment process and the induction of a delayed sleep phase due to the lingering presence of melatonin, or the phase-delaying effects of a strong melatonin signal much later than the ideal DLMO. Giving higher doses at bedtime will induce sleep but may cause a circadian phase delay, effectively “jet lagging” the patient. We recommend prescribing low-dose melatonin (LDM; 0.5 to 1 mg) 2 to 4 hours before the intended bedtime rather than higher doses (≥5 mg) given at bedtime as is common practice and recommended by many melatonin manufacturers. LDM better simulates the natural release and function of melatonin and avoids potential adverse circadian phase delays. The successful use of melatonin in hospitalized patients suggests there is a unique opportunity to use this safe and effective medication with a relatively well-understood mechanism of action for nonhospitalized patients who are having difficulty sleeping. Considering the known physiological actions of melatonin can help guide the optimal timing and dosage of melatonin for this purpose.

The Spanish Society of Pulmonology and Thoracic Surgery (SEPAR) has issued a new international consensus document (ICD) on obstructive sleep apnea (OSA). The objective is to improve the diagnosis and treatment of one of the most prevalent sleep disorders.

The ICD represents a collaboration of experts from 17 scientific societies and 56 specialists from various countries. It provides a series of clinical guidelines to help health care professionals make the best decisions for adult patients with OSA. Notably, the authors propose changing the name from sleep apnea syndrome. In recommending the term OSA, they reintroduce the term “obstructive” – to differentiate the disorder from central sleep apnea – and remove the outdated word “syndrome.”

“The definition has also been changed, as it was a bit vague and difficult to understand. And there are significant changes to the treatment and to the diagnostic algorithms – one for primary care and another for sleep units,” Olga Mediano, MD, said in an interview. She is a SEPAR pulmonologist, first author of the ICD, and the coordinator of SEPAR 2022 Year of Intermediate Respiratory Care Units.
 

Diagnosis in primary care

The ICD indicates that all levels of care must be involved in the management of OSA, a condition in which complete or partial upper airway blockage occurs during sleep, causing the individual to stop breathing for a few seconds. These pauses, which produce hypoxia and sleep fragmentation, increase the risk of workplace and traffic accidents, affect cardiovascular health, and contribute to uncontrolled or resistant hypertension.

The recommendations in the ICD aim at increasing the role of primary care physicians so as to reduce underdiagnosis of OSA in primary care. “The vast majority of patients with OSA haven’t been diagnosed. In fact, those whom we have diagnosed are the patients with the most severe cases – in other words, patients who present with the most symptoms,” said Dr. Mediano. She explained that many patients with OSA don’t consider it a medical condition, so they do not go to the doctor.

“The other big problem is that, before, there was a preconceived notion of the typical OSA patient: A middle-aged obese man who’s fallen asleep in the waiting room. However, there are many other profiles: thin build, women. ... Sleep has a heterogeneous profile, and all profiles need to be known,” said Dr. Mediano. The difficulties in carrying out a sleep study with the various patients are an added problem that the new consensus document also seeks to resolve. “The step we’ve taken is to involve the primary care physician in super-simplified studies to reach more people,” she said. For this, the primary care site must work in coordination with a sleep unit.

“In the super-simplified study, the patient is given a machine to use at home; they hook themselves up to it when they go to sleep. This machine records the number of apnea episodes the patient experiences during the night, as well as the oxygen level. The next day, the patient returns the machine. The data are downloaded to a computer. The software analyzes the breathing pauses that the patient had during the night and automatically gives a series of values that, if very pronounced, as the document indicates, would lead to a diagnosis of OSA. Once diagnosed by a primary care physician, the patient is referred to a sleep unit where treatment can then be assessed,” explained Dr. Mediano.
 

Different treatments

The new ICD’s approach incorporates therapeutic alternatives as well. Until now, many consensus documents and clinical guidelines have focused on continuous positive airway pressure therapy, in which a machine delivers continuous airflow to help keep the patient’s airway open and unobstructed during sleep. Some guidelines recommend its use, and others do not. “However, in this new document, management of the patient is much more multidisciplinary. What changes, with respect to the treatment, is the philosophy. It’s not one single type of treatment; rather, other therapeutic options are kept in mind,” said Dr. Mediano.

First, treatment of reversible causes of OSA must be offered. The conditions that lead to OSA and that can be reversed are addressed. These include overweight and obesity; heavy drinking; tonsillar hypertrophy, or severe dental or facial alterations, for which surgery can be considered; and gastroesophageal reflux or hypothyroidism, both of which can be treated. “For example, the leading cause of sleep apnea is obesity. If we can get the patient to lose weight, that can end up making the OSA go away. What does the document say? Well, you have to try to implement intensive strategies regarding diet, exercise, etc. And if that’s not enough, you need to consider using drugs or even bariatric surgery,” said Dr. Mediano.

“If there’s no one definitive treatment, we highly recommend that all patients implement hygienic-dietary measures and then assess all the therapeutic options. In some cases, several can be in place at the same time,” she said. Various medical specialists can play a role in the treatment of OSA, said Dr. Mediano. They include otolaryngologists, maxillofacial surgeons, dentists, cardiologists, and neurophysiologists, to mention a few.

The Spanish Society of Pulmonology and Thoracic Surgery (SEPAR) has issued a new international consensus document (ICD) on obstructive sleep apnea (OSA). The objective is to improve the diagnosis and treatment of one of the most prevalent sleep disorders.

The ICD represents a collaboration of experts from 17 scientific societies and 56 specialists from various countries. It provides a series of clinical guidelines to help health care professionals make the best decisions for adult patients with OSA. Notably, the authors propose changing the name from sleep apnea syndrome. In recommending the term OSA, they reintroduce the term “obstructive” – to differentiate the disorder from central sleep apnea – and remove the outdated word “syndrome.”

“The definition has also been changed, as it was a bit vague and difficult to understand. And there are significant changes to the treatment and to the diagnostic algorithms – one for primary care and another for sleep units,” Olga Mediano, MD, said in an interview. She is a SEPAR pulmonologist, first author of the ICD, and the coordinator of SEPAR 2022 Year of Intermediate Respiratory Care Units.
 

Diagnosis in primary care

The ICD indicates that all levels of care must be involved in the management of OSA, a condition in which complete or partial upper airway blockage occurs during sleep, causing the individual to stop breathing for a few seconds. These pauses, which produce hypoxia and sleep fragmentation, increase the risk of workplace and traffic accidents, affect cardiovascular health, and contribute to uncontrolled or resistant hypertension.

The recommendations in the ICD aim at increasing the role of primary care physicians so as to reduce underdiagnosis of OSA in primary care. “The vast majority of patients with OSA haven’t been diagnosed. In fact, those whom we have diagnosed are the patients with the most severe cases – in other words, patients who present with the most symptoms,” said Dr. Mediano. She explained that many patients with OSA don’t consider it a medical condition, so they do not go to the doctor.

“The other big problem is that, before, there was a preconceived notion of the typical OSA patient: A middle-aged obese man who’s fallen asleep in the waiting room. However, there are many other profiles: thin build, women. ... Sleep has a heterogeneous profile, and all profiles need to be known,” said Dr. Mediano. The difficulties in carrying out a sleep study with the various patients are an added problem that the new consensus document also seeks to resolve. “The step we’ve taken is to involve the primary care physician in super-simplified studies to reach more people,” she said. For this, the primary care site must work in coordination with a sleep unit.

“In the super-simplified study, the patient is given a machine to use at home; they hook themselves up to it when they go to sleep. This machine records the number of apnea episodes the patient experiences during the night, as well as the oxygen level. The next day, the patient returns the machine. The data are downloaded to a computer. The software analyzes the breathing pauses that the patient had during the night and automatically gives a series of values that, if very pronounced, as the document indicates, would lead to a diagnosis of OSA. Once diagnosed by a primary care physician, the patient is referred to a sleep unit where treatment can then be assessed,” explained Dr. Mediano.
