Philips Respironics Issues Update on Ventilator Alarm Failure
, according to a recall statement from the US Food and Drug Administration (FDA).
The OLA+ Ventilator is designed for use by individuals with obstructive sleep apnea, breathing problems, and mixed apnea and is approved for children aged 7 years and older, as well as adults.
The recall does not involve removal of the devices from where they are used or sold but does update the instructions for use, and its use without following the updated instructions could result in serious injury or death, according to the statement.
Following an alarm failure, the device may fail in one of two ways: By entering a ventilator inoperative state after three reboots within 24 hours (with no therapy and audible and visual alarms present) or by entering a ventilator inoperative state without rebooting first.
According to the statement, the alarm issue may be corrected with a software patch, available from Philips, or the company will offer a replacement device for patients until the affected devices are repaired. The statement updates an April 1, 2024, urgent recall from Philips urging the immediate removal of a patient from an OLA+ Ventilator and connecting them to alternative ventilation if possible if the ventilator’s inoperative alarm occurs.
The device failures may cause interruption or loss of therapy with effects including anxiety, confusion/disorientation, changes in respiratory rate, dyspnea, tachycardia, respiratory failure, and even death in especially vulnerable individuals. One death and 15 injuries have been reported as a result of the alarm failure, according to the FDA.
US customers can contact Philips Respironics Inc. at 1-800-345-6443 or [email protected] with questions, according to the FDA, and clinicians and patients may report adverse reactions or other problems with the devices to MedWatch: The FDA Safety Information and Adverse Event Reporting Program.

What Is a Blue Zone Certified Clinician?
It is a great day when a patient shows up at clinical appointment already motivated to make lifestyle behavior changes. Often, they have been inspired by health information they consumed elsewhere, such as from a book, movie, documentary, TV show, a friend, or something out in the community.
Currently, one of the more public representations of health and longevity promotion is Blue Zones. The organization, named for specific areas of the world — the so-called blue zones, where people experience less disease and live longer lives — has created considerable public awareness for healthy living. Today, there are more than 75 Blue Zones Project communities across the United States, where community leaders, businesses, organizations, and citizens collaborate to make healthier choices the easier choices. A recent Netflix special, Live to 100: Secrets of the Blue Zones, further propelled blue zones into the public consciousness.
The Blue Zones emphasis on “plant-slant” diet, natural movement, purpose and contribution, downshifting, and family and community intersect with the lifestyle medicine pillars of whole-food, plant-predominant eating patterns, regular physical activity, stress management, restorative sleep, and positive social connections. Both Blue Zones and lifestyle medicine share a goal of creating healthier and stronger individuals and communities.
For those reasons, it made perfect sense that Blue Zones and the American College of Lifestyle Medicine (ACLM) recently announced a partnership to synergize both organizations’ strengths and resources. Among other things, the collaboration will establish a new certification status of Blue Zones–Certified Physician or Blue Zones–Certified Healthcare Professional, available in 2025 exclusively to clinicians who already are or become certified in lifestyle medicine.
Because of Blue Zones’ considerable consumer awareness, physicians and other health professionals who earn the certification will stand out to potential patients as clinicians with the training and knowledge to help them make sustainable lifestyle behavior changes. A challenging part of any clinician’s job is educating and convincing patients on the proven health benefits of lifestyle behavior change within the time restraints of a routine clinical visit. Patients familiar with Blue Zones are more likely to arrive already interested in changing lifestyle behavior, and clinicians should have the skills to help them achieve their goals.
In addition, community infrastructure developed through Blue Zones that supports healthful lifestyle choices is significant for patients. Lack of resources in their home, work, and community environments is a common obstacle that patients cite when discussing lifestyle change with a clinician. Bicycle lanes for commuting, parks with exercise equipment, accessible healthy food options, and community events to facilitate positive social connections enhance lifestyle-medicine prescriptions. Workplaces, restaurants, places of worship, and grocery stores are examples of community stakeholders that collaborate in Blue Zones communities to promote healthy lifestyle decisions. Although lifestyle medicine clinicians can and do identify creative ways to support patients in communities without strong healthy choice infrastructure, the Blue Zones road map is a welcome companion.
The timing is right for this synthesis of Blue Zones and lifestyle medicine. As consumer interest in Blue Zones has risen, so has clinician interest in evidence-based lifestyle medicine. Since certification in lifestyle medicine began in 2017, almost 6700 physicians and other health professionals have become certified worldwide. More than 43,000 health care professionals have registered for ACLM’s complimentary lifestyle and food-as-medicine courses highlighted by the White House Conference on Hunger, Nutrition, and Health.
What if more patients came to us motivated to make lifestyle changes because of awareness infused in their work and supported in their surrounding community? Matching lifestyle medicine certification with Blue Zone communities equips clinicians to help these patients achieve what they really want: to live longer and better.

Benzos Are Hard on the Brain, But Do They Raise Dementia Risk?
The study of more than 5000 older adults found that benzodiazepine use was associated with an accelerated reduction in the volume of the hippocampus and amygdala — brain regions involved in memory and mood regulation. However, benzodiazepine use overall was not associated with an increased risk for dementia.
The findings suggest that benzodiazepine use “may have subtle, long-term impact on brain health,” lead investigator Frank Wolters, MD, PhD, with Erasmus University Medical Center, Rotterdam, the Netherlands, and colleagues wrote.
The study was published online in BMC Medicine.
Conflicting Evidence
Benzodiazepines are commonly prescribed in older adults for anxiety and sleep disorders. Though the short-term cognitive side effects are well documented, the long-term impact on neurodegeneration and dementia risk remains unclear. Some studies have linked benzodiazepine use to an increased risk for dementia, whereas others have not.
Dr. Wolters and colleagues assessed the effect of benzodiazepine use on long-term dementia risk and on imaging markers of neurodegeneration in 5443 cognitively healthy adults (mean age, 71 years; 57% women) from the population-based Rotterdam Study.
Benzodiazepine use between 1991 and 2008 was determined using pharmacy dispensing records, and dementia incidence was determined from medical records.
Half of the participants had used benzodiazepines at any time in the 15 years before baseline (2005-2008); 47% used anxiolytics, 20% used sedative-hypnotics, 34% used both, and 13% were still using the drugs at the baseline assessment.
During an average follow-up of 11 years, 13% of participants developed dementia.
Overall, use of benzodiazepines was not associated with dementia risk, compared with never-use (hazard ratio [HR], 1.06), irrespective of cumulative dose.
The risk for dementia was somewhat higher with any use of anxiolytics than with sedative-hypnotics (HR, 1.17 vs HR, 0.92), although neither was statistically significant. The highest risk estimates were observed for high cumulative dose of anxiolytics (HR, 1.33).
Sensitivity analyses of the two most commonly used anxiolytics found no differences in risk between use of short half-life oxazepam and long half-life diazepam (HR, 1.01 and HR, 1.06, respectively, for ever-use, compared with never-use for oxazepam and diazepam).
Brain Atrophy
The researchers investigated potential associations between benzodiazepine use and brain volumes using brain MRI imaging from 4836 participants.
They found that current use of a benzodiazepine at baseline was significantly associated with lower total brain volume — as well as lower hippocampus, amygdala, and thalamus volume cross-sectionally — and with accelerated volume loss of the hippocampus and, to a lesser extent, amygdala longitudinally.
Imaging findings did not differ by type of benzodiazepine used or cumulative dose.
“Given the availability of effective alternative pharmacological and nonpharmacological treatments for anxiety and sleep problems, it is important to carefully consider the necessity of prolonged benzodiazepine use in light of potential detrimental effects on brain health,” the authors wrote.
Risks Go Beyond the Brain
Commenting on the study, Shaheen Lakhan, MD, PhD, a neurologist and researcher based in Miami, Florida, noted that “chronic benzodiazepine use may reduce neuroplasticity, potentially interfering with the brain’s ability to form new connections and adapt.
“Long-term use can lead to down-regulation of GABA receptors, altering the brain’s natural inhibitory mechanisms and potentially contributing to tolerance and withdrawal symptoms. Prolonged use can also disrupt the balance of various neurotransmitter systems beyond just GABA, potentially affecting mood, cognition, and overall brain function,” said Dr. Lakhan, who was not involved in the study.
“While the literature is mixed on chronic benzodiazepine use and dementia risk, prolonged use has consistently been associated with accelerated volume loss in certain brain regions, particularly the hippocampus and amygdala,” which are responsible for memory, learning, and emotional regulation, he noted.
“Beyond cognitive impairments and brain volume loss, chronic benzodiazepine use is associated with tolerance and dependence, potential for abuse, interactions with other drugs, and increased fall risk, especially in older adults,” Dr. Lakhan added.
Current guidelines discourage long-term use of benzodiazepines because of risk for psychological and physical dependence; falls; and cognitive impairment, especially in older adults. Nevertheless, research shows that 30%-40% of older benzodiazepine users stay on the medication beyond the recommended period of several weeks.
Donovan T. Maust, MD, Department of Psychiatry, University of Michigan Medical School, Ann Arbor, said in an interview these new findings are consistent with other recently published observational research that suggest benzodiazepine use is not linked to dementia risk.
“I realize that such meta-analyses that find a positive relationship between benzodiazepines and dementia are out there, but they include older, less rigorous studies,” said Dr. Maust, who was not part of the new study. “In my opinion, the jury is not still out on this topic. However, there are plenty of other reasons to avoid them — and in particular, starting them — in older adults, most notably the increased risk of fall injury as well as increased overdose risk when taken along with opioids.”

Post–intensive care syndrome and insomnia
SLEEP MEDICINE NETWORK
Nonrespiratory Sleep Section
There has been a recent interest in post–intensive care syndrome (PICS), as an increasing number of patients are surviving critical illness. PICS is defined as “new onset or worsening of impairments in physical, cognitive, and/or mental health that arises after an ICU stay and persists beyond hospital discharge.1 We know that poor sleep is a common occurrence in the ICU, which can contribute to cognitive impairment and could be due to various risk factors, including age, individual comorbidities, reason for admission, and ICU interventions.2 Sleep impairment after hospital discharge is highly prevalent for up to 1 year after hospitalization.
The most common sleep impairment described after hospital discharge from the ICU is insomnia, which coexists with anxiety, depression, and posttraumatic stress disorder.3 When patients are seen in a post-ICU clinic, a multimodal strategy is needed for the treatment of insomnia, which includes practicing good sleep hygiene, cognitive behavioral therapy for insomnia (CBT-I), and pharmacotherapy if indicated.
Since the American Academy of Sleep Medicine (AASM) 2021 clinical practice guideline on behavioral and psychological treatments for chronic insomnia, which made a strong recommendation for CBT-I, we continue to face barriers to incorporating CBT-I into our own clinical practice.4 This is due to limited access to CBT-I psychotherapists and patients’ lack of knowledge or treatment beliefs, among other reasons. However, there are numerous digital CBT-I platforms that patients can freely access from their mobile phone and are listed in the AASM article, “Digital cognitive behavioral therapy for insomnia: Platforms and characteristics,” which can help with treatment of insomnia.
For patients who are seen in post-ICU clinics, the first step in treating insomnia is discussing good sleep hygiene, providing resources for CBT-I (digital or in person), and treating coexistent psychiatric conditions.

The most common sleep impairment described after hospital discharge from the ICU is insomnia, which coexists with anxiety, depression, and posttraumatic stress disorder.3 When patients are seen in a post-ICU clinic, a multimodal strategy is needed for the treatment of insomnia, which includes practicing good sleep hygiene, cognitive behavioral therapy for insomnia (CBT-I), and pharmacotherapy if indicated.
Since the American Academy of Sleep Medicine (AASM) 2021 clinical practice guideline on behavioral and psychological treatments for chronic insomnia, which made a strong recommendation for CBT-I, we continue to face barriers to incorporating CBT-I into our own clinical practice.4 This is due to limited access to CBT-I psychotherapists and patients’ lack of knowledge or treatment beliefs, among other reasons. However, there are numerous digital CBT-I platforms that patients can freely access from their mobile phone and are listed in the AASM article, “Digital cognitive behavioral therapy for insomnia: Platforms and characteristics,” which can help with treatment of insomnia.
For patients who are seen in post-ICU clinics, the first step in treating insomnia is discussing good sleep hygiene, providing resources for CBT-I (digital or in person), and treating coexistent psychiatric conditions.

More Evidence PTSD Tied to Obstructive Sleep Apnea Risk
Posttraumatic stress disorder (PTSD) may enhance the risk for obstructive sleep apnea (OSA) in older male veterans, the results of a cross-sectional twin study suggested. However, additional high-quality research is needed and may yield important mechanistic insights into both conditions and improve treatment, experts said.
“The strength of the association was a bit surprising,” said study investigator Amit J. Shah, MD, MSCR, Emory University, Atlanta, Georgia. “Many physicians and scientists may otherwise assume that the relationship between PTSD and sleep apnea would be primarily mediated by obesity, but we did not find that obesity explained our findings.”
The study was published online in JAMA Network Open.
A More Rigorous Evaluation
“Prior studies have shown an association between PTSD and sleep apnea, but the size of the association was not as strong,” Dr. Shah said, possibly because many were based on symptomatic patients referred for clinical evaluation of OSA and some relied on self-report of a sleep apnea diagnosis.
The current study involved 181 male twins, aged 61-71 years, including 66 pairs discordant for PTSD symptoms and 15 pairs discordant for PTSD diagnosis, who were recruited from the Vietnam Era Twin Registry and underwent a formal psychiatric and polysomnography evaluation as follow-up of the Emory Twin Study.
PTSD symptom severity was assessed using the self-administered Posttraumatic Stress Disorder Checklist (PCL). OSA was mild in 74% of participants, moderate to severe in 40%, and severe in 18%.
The mean apnea-hypopnea index (AHI) was 17.7 events per hour, and the mean proportion of the night with SaO2 less than 90% was 8.9%.
In fully adjusted models, each 15-point within-pair difference in PCL score was associated with a 4.6 events-per-hour higher AHI, a 6.4 events-per-hour higher oxygen desaturation index, and a 4.8% greater sleep duration with SaO2 less than 90%.
A current PTSD diagnosis is associated with an approximate 10-unit higher adjusted AHI in separate models involving potential cardiovascular mediators (10.5-unit; 95% CI, 5.7-15.3) and sociodemographic and psychiatric confounders (10.7-unit; 95% CI, 4.0-17.4).
The investigators called for more research into the underlying mechanisms but speculated that pharyngeal collapsibility and exaggerated loop gain, among others, may play a role.
“Our findings broaden the concept of OSA as one that may involve stress pathways in addition to the traditional mechanisms involving airway collapse and obesity,” Dr. Shah said. “We should be more suspicious of OSA as an important comorbidity in PTSD, given the high OSA prevalence that we found in PTSD veterans.”
Questions Remain
In an accompanying editorial, Steven H. Woodward, PhD, and Ruth M. Benca, MD, PhD, VA Palo Alto Health Care Systems, Palo Alto, California, noted the study affirmatively answers the decades-old question of whether rates of OSA are elevated in PTSD and “eliminates many potential confounders that might cast doubt on the PTSD-OSA association.”
However, they noted, it’s difficult to ascertain the directionality of this association and point out that, in terms of potential mechanisms, the oft-cited 1994 study linking sleep fragmentation with upper airway collapsibility has never been replicated and that a recent study found no difference in airway collapsibility or evidence of differential loop gain in combat veterans with and without PTSD.
Dr. Woodward and Dr. Benca also highlighted the large body of evidence that psychiatric disorders such as bipolar disorder, schizophrenia, and, in particular, major depressive disorder, are strongly associated with higher rates of OSA.
“In sum, we do not believe that a fair reading of the current literature supports a conclusion that PTSD bears an association with OSA that does not overlap with those manifested by other psychiatric disorders,” they wrote.
“This commentary is not intended to discourage any specific line of inquiry. Rather, we seek to keep the door open as wide as possible to hypotheses and research designs aimed at elucidating the relationships between OSA and psychiatric disorders,” Dr. Woodward and Dr. Benca concluded.
In response, Dr. Shah said the editorialists’ “point about psychiatric conditions other than PTSD also being important in OSA is well taken. In our own cohort, we did not see such an association, but that does not mean that this does not exist.
“Autonomic physiology, which we plan to study next, may underlie not only the PTSD-OSA relationship but also the relationship between other psychiatric factors and OSA,” he added.
The study was funded by grants from the National Institutes of Health (NIH). One study author reported receiving personal fees from Idorsia, and another reported receiving personal fees from Clinilabs, Eisai, Ferring Pharmaceuticals, Huxley, Idorsia, and Merck Sharp & Dohme. Dr. Benca reported receiving grants from the NIH and Eisai and personal fees from Eisai, Idorsia, Haleon, and Sage Therapeutics. Dr. Woodward reported having no relevant conflicts of interest.

Ghrelin Paradox: Unlocking New Avenues in Obesity Management
Despite their best efforts, 80% of people who lose weight regain it and many end up heavier within 5 years. Why? Our bodies fight back, revving up hunger while slowing metabolism after weight loss. In ongoing obesity discussions, ghrelin is in the spotlight as the “hunger hormone” playing a crucial role in driving appetite and facilitating weight gain.
Weight loss interventions, such as diet or gastric bypass surgery, may trigger an increase in ghrelin levels, potentially fueling long-term weight gain. Consequently, ghrelin remains a focal point of research into innovative antiobesity treatments.
Ghrelin, a hormone produced in the stomach, is often called the “hunger hormone.” Ghrelin is a circulating orexigenic gut hormone with growth hormone–releasing activity.
Since the discovery of ghrelin, in 1999, research in mice and people has focused on its effect on regulating appetite and implications for long-term weight control. When hunger strikes, ghrelin levels surge, sending signals to the brain that ramp up the appetite. Following a meal, ghrelin decreases, indicating fullness.
Studies have found that people who were injected with subcutaneous ghrelin experienced a 46% increase in hunger and ate 28% more at their next meal than those who didn’t receive a ghrelin injection.
We might expect high levels of ghrelin in individuals with obesity, but this is not the case. In fact, ghrelin levels are typically lower in individuals with obesity than in leaner individuals. This finding might seem to contradict the idea that obesity is due to high levels of the hunger hormone.
Excess weight could increase sensitivity to ghrelin, where more receptors lead to higher hunger stimulation with less ghrelin. Beyond hunger, ghrelin can also lead us to eat for comfort, as when stressed or anxious. Ghrelin and synthetic ghrelin mimetics increase body weight and fat mass by activating receptors in the arcuate nucleus of the hypothalamus (Müller et al.; Bany Bakar et al.). There, it also activates the brain’s reward pathways, making us crave food even when we are not hungry. This connection between ghrelin and emotional eating can contribute to stress-induced obesity.
In my clinical practice, I have seen individuals gain maximum weight when they are under more stress and are sleep-deprived. This is because ghrelin levels increased in these scenarios. This elevation of ghrelin in high-stress, low-sleep situations affects weight gain in women during the postpartum period and menopause.
Evidence also suggests that certain foods affect ghrelin levels. After a person eats carbohydrates, their ghrelin levels initially decrease quickly, but this is followed by a rise in ghrelin, leading them to become hungry again. In contrast, protein intake helps suppress ghrelin levels for longer. Hence, we advise patients to increase protein intake while reducing their carb intake, or to always eat protein along with carbs.
It makes sense that when individuals with obesity lose weight by fasting or caloric restriction and try to maintain that weight loss, their bodies tend to produce more ghrelin. This effect might explain why people who lose weight often find it hard to keep it off: Rising ghrelin levels after weight loss might drive them to eat more and regain weight.
Two prominent weight loss surgeries, sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB), have opposite effects on ghrelin levels, reflecting their distinct mechanisms for weight loss. SG involves removal of the gastric fundus, where ghrelin is produced, resulting in a significant decrease in ghrelin levels; RYGB operates through malabsorption without directly affecting ghrelin production. Despite these differing approaches, both techniques demonstrate remarkable weight loss efficacy. Research comparing the two procedures reveals that SG leads to decreased fasting plasma ghrelin levels, whereas RYGB prompts an increase, highlighting the additional appetite-reducing mechanism of SG through ghrelin suppression. This contrast underscores the intricate role of ghrelin in appetite regulation and suggests that its manipulation can significantly influence weight loss outcomes.
With the effect of ghrelin in stimulating appetite being established, other studies have explored the relationship between ghrelin and insulin resistance. A meta-analysis by researchers at Qingdao University, Qingdao, China, found that circulating ghrelin levels were negatively correlated with insulin resistance in individuals with obesity and normal fasting glucose levels. The findings suggest that the role of ghrelin in obesity might extend beyond appetite regulation to influence metabolic pathways and that ghrelin may be a marker for predicting obesity.
Researchers are exploring potential therapeutic targets focusing on ghrelin modulation. Although selective neutralization of ghrelin has not yielded consistent results in rodent models, the interplay between ghrelin and LEAP2— a hormone that attaches to the same brain receptors — could be an area of interest for future obesity treatments.
Could ghrelin be the key to tackling obesity? Blocking ghrelin pharmacologically might be a strategy to keep weight off after weight loss, and it could help prevent the typical rebound effect seen with diets and withdrawal of medications. Considering the high rates of weight regain after diet-induced weight loss and withdrawal of weight loss medications, targeting ghrelin might be the missing link in long-term obesity treatment. It could be a valuable approach to improving long-term outcomes for obesity. However, these blockers might have significant side effects, given that ghrelin affects not only hunger but also the brain’s reward and pleasure centers. Therefore, caution will be needed in developing such medications owing to their potential impact on mood and mental health.
With ghrelin playing roles in hunger, reward pathways, and energy regulation, understanding this hormone is crucial in the fight against obesity. Stay tuned for future research that could shed light on the underlying mechanisms at play and hopefully results in clinical action steps.

Research comparing the two procedures reveals that SG leads to decreased fasting plasma ghrelin levels, whereas RYGB prompts an increase, highlighting the additional appetite-reducing mechanism of SG through ghrelin suppression. This contrast underscores the intricate role of ghrelin in appetite regulation and suggests that its manipulation can significantly influence weight loss outcomes.
With the effect of ghrelin in stimulating appetite being established, other studies have explored the relationship between ghrelin and insulin resistance. A meta-analysis by researchers at Qingdao University, Qingdao, China, found that circulating ghrelin levels were negatively correlated with insulin resistance in individuals with obesity and normal fasting glucose levels. The findings suggest that the role of ghrelin in obesity might extend beyond appetite regulation to influence metabolic pathways and that ghrelin may be a marker for predicting obesity.
Researchers are exploring potential therapeutic targets focusing on ghrelin modulation. Although selective neutralization of ghrelin has not yielded consistent results in rodent models, the interplay between ghrelin and LEAP2— a hormone that attaches to the same brain receptors — could be an area of interest for future obesity treatments.
Could ghrelin be the key to tackling obesity? Blocking ghrelin pharmacologically might be a strategy to keep weight off after weight loss, and it could help prevent the typical rebound effect seen with diets and withdrawal of medications. Considering the high rates of weight regain after diet-induced weight loss and withdrawal of weight loss medications, targeting ghrelin might be the missing link in long-term obesity treatment. It could be a valuable approach to improving long-term outcomes for obesity. However, these blockers might have significant side effects, given that ghrelin affects not only hunger but also the brain’s reward and pleasure centers. Therefore, caution will be needed in developing such medications owing to their potential impact on mood and mental health.
With ghrelin playing roles in hunger, reward pathways, and energy regulation, understanding this hormone is crucial in the fight against obesity. Stay tuned for future research that could shed light on the underlying mechanisms at play and hopefully results in clinical action steps.

Tirzepatide Reduces Sleep Interruptions, Halting Almost Half of CPAP Use
ORLANDO, FLA. — The diabetes and weight loss drug tirzepatide (Mounjaro for type 2 diabetes; Zepbound for obesity) was so effective at reducing sleep disruptions in patients with obesity and obstructive sleep apnea (OSA) that 40%-50% no longer needed to use a continuous positive airway pressure (CPAP) device, according to two new studies.
Tirzepatide, a long-acting glucose-dependent insulinotropic polypeptide (GIP) receptor agonist and glucagon-like peptide 1 (GLP-1) receptor agonist, also lowered C-reactive protein levels and systolic blood pressure. And patients taking the medication lost 18%-20% of their body weight.
said lead author Atul Malhotra, MD, professor of medicine at the University of California, San Diego, and director of sleep medicine at UC San Diego Health.
The two double-blind, randomized, controlled trials in patients with obesity and moderate to severe OSA were conducted at 60 sites in nine countries. The results were presented at the American Diabetes Association (ADA) 84th Scientific Sessions and simultaneously published online in the New England Journal of Medicine.
OSA affects 1 billion people worldwide and 30 million American adults, many of whom are undiagnosed. Obesity is a common risk factor. According to the ADA, 40% of those with obesity have OSA and 70% of those with OSA have obesity.
CPAP is an effective and the most-used intervention for OSA, but many patients refuse to use the device, stop using it, or cannot use it. Should tirzepatide eventually gain Food and Drug Administration approval for OSA, it would be the first drug approved for the condition.
“This new drug treatment offers a more accessible alternative for individuals who cannot tolerate or adhere to existing therapies,” said Dr. Malhotra.
Huge Reduction in Episodes, Severity
For the two studies, patients were enrolled who had moderate to severe OSA, defined as more than 15 events per hour (using the apnea-hypopnea index [AHI]) and a body mass index of 30 kg/m2 or greater. Those not using a CPAP device were enrolled in study 1, and those using a CPAP device were enrolled in study 2.
Participants received either the maximum tolerated dose of tirzepatide (10 or 15 mg by once-weekly injection) or placebo for 1 year. In study 1, 114 individuals received tirzepatide and 120 received placebo. For study 2, 119 patients received tirzepatide and 114 received placebo. All participants received regular lifestyle counseling sessions about nutrition and were instructed to reduce food intake by 500 kcal/day and to engage in at least 150 min/week of physical activity.
Enrollment was limited to 70% men to ensure adequate representation of women.
At baseline, 65%-70% of participants had severe OSA, with more than 30 events/hour on the AHI scale and a mean of 51.5 events/hour.
By 1 year, patients taking tirzepatide had 27-30 fewer events/hour, compared with 4-6 fewer events/hour for those taking placebo.
Up to half of those who received tirzepatide in both trials had less than 5 events/hour or 5-14 AHI events/hour and an Epworth Sleepiness Scale score of 10 or less. Those thresholds “represent a level at which CPAP therapy may not be recommended,” wrote the authors.
Patients in the tirzepatide group also had a decrease in systolic blood pressure from baseline of 9.7 mm Hg in study 1 and 7.6 mm Hg in study 2 at week 48.
The most common adverse events were diarrhea, nausea, and vomiting, which occurred in approximately a quarter of patients taking tirzepatide. There were two adjudicated-confirmed cases of acute pancreatitis in those taking tirzepatide in study 2.
Patients who received tirzepatide also reported fewer daytime and nighttime disturbances, as measured using the Patient-Reported Outcomes Measurement Information System Short Form scale for Sleep-Related Impairment and Sleep Disturbance.
Tirzepatide Plus CPAP Are Best
Writing in an accompanying editorial, Sanjay R. Patel, MD, noted that, although clinical guidelines have recommended that weight loss strategies be incorporated as part of OSA treatment, “the integration of obesity management into the approaches to care for obstructive sleep apnea has lagged.”
As many as half of patients abandon CPAP therapy within 3 years, wrote Dr. Patel, who is professor of medicine and epidemiology at the University of Pittsburgh, Pittsburgh, Pennsylvania, and medical director of the UPMC Comprehensive Sleep Disorders program. “An effective medication to treat obesity is thus an obvious avenue to pursue.”
Dr. Patel noted the large reductions in the number of events on the AHI scale. He wrote that the improvement in systolic blood pressure “was substantially larger than effects seen with CPAP therapy alone and indicate that tirzepatide may be an attractive option for those patients who seek to reduce their cardiovascular risk.”
Dr. Patel raised concerns about whether patients outside of a trial would stick with therapy, noting studies have shown high rates of discontinuation of GLP-1 receptor agonists.
And, he wrote, “racial disparities in the use of GLP-1 receptor agonists among patients with diabetes arouse concern that the addition of tirzepatide as a treatment option for obstructive sleep apnea without directly addressing policies relative to coverage of care will only further exacerbate already pervasive disparities in clinical care for obstructive sleep apnea.”
Commenting on the study during the presentation of the results, Louis Aronne, MD, said he believes the trials demonstrate “the treatment of obesity with tirzepatide plus CPAP is really the optimal treatment for obstructive sleep apnea and obesity-related cardiometabolic risks.” Dr. Aronne is the Sanford I. Weill professor of metabolic research at Weill Cornell Medical College, New York City.
Dr. Aronne added there is still much to learn. It is still not clear whether tirzepatide had an independent effect in the OSA trial — as has been seen in other studies where the drug clearly reduced cardiovascular risk — or whether the positive results were primarily caused by weight loss.
“I believe that over time we’ll see that this particular effect in sleep apnea is related to weight,” he said.
The study was supported by Eli Lilly. Dr. Malhotra has reported being a paid consultant for Lilly and ZOLL Medical and a cofounder of Healcisio.

Urgent Need for Better Care, New Policies to Lower Insomnia Burden
HOUSTON — A new analysis highlights the high burden of insomnia across the Americas, with about 17% of adults suffering from this chronic sleep disorder.
“Our findings underscore the urgent need for enhanced clinical care pathways and policy interventions to effectively diagnose and treat insomnia. It is crucial to foster greater awareness of the critical role that sleep plays in overall health,” lead investigator Adam Benjafield, PhD, vice president for medical affairs at ResMed, Sydney, Australia, said in an interview.
“Insomnia not only affects individuals’ health and quality of life but also has broader implications for public health systems. Developing comprehensive care strategies and promoting education about sleep health could significantly improve outcomes for individuals suffering from insomnia disorder,” Dr. Benjafield said.
The findings were presented at SLEEP 2024: 38th Annual Meeting of the Associated Professional Sleep Societies.
Underdiagnosed, Undertreated
Sleep disruptions contribute to various medical problems, including cognitive impairment, reduced immune function, metabolic imbalance, and exacerbation of psychiatric conditions. While the prevalence of insomnia in developed countries like the United States and Canada is known, there is limited epidemiologic evidence, and no reliable estimate for the disorder across the Americas — especially in low- and middle-income countries.
The researchers used published nation-specific data to estimate the prevalence of adult insomnia disorder across the 55 countries defined by the United Nations as comprising the Americas.
Based on the available data, the researchers estimated that about 123 million adults across the Americas have insomnia disorder (16.8%) — with greater prevalence in women (73 million, 19.5%) than in men (50 million, 14%).
The nations with the greatest burden of insomnia disorder are the United States (37 million), Brazil (29 million), and Mexico (16 million).
“While our study did not specifically investigate trends over time due to its scope, evidence from other research suggests that insomnia is becoming more prevalent over the long term. This growing trend highlights the increasing need for awareness and intervention in managing sleep health,” Dr. Benjafield said.
Insomnia is underdiagnosed and undertreated partly because of general lack of awareness about the importance of addressing sleep disorders and the fact that cognitive-behavioral therapy for insomnia (CBT-I), which is recommended as first-line treatment, is not widely accessible because of a shortage of trained CBT-I practitioners.
“Many individuals with insomnia struggle to find and receive this effective nonpharmacological treatment. Consequently, there is an overreliance on pharmaceutical solutions, which are ideally used for short-term management but are often extended due to the lack of alternatives. These medications can lead to dependency and other side effects,” Dr. Benjafield said.
Ask About Sleep
Insomnia symptoms are a “common presenting complaint in doctors’ offices in the United States. The percentages in this poster show that insomnia disorder has a similar, high percent prevalence across countries in the Americas,” Boris Gilyadov, MD, assistant professor of pulmonary, critical care, and sleep medicine at the Icahn School of Medicine at Mount Sinai in New York City, said in an interview.
“During preventive care visits and general physical exams, patients should be asked about the quality of their sleep. Patients may benefit from a referral to the sleep medicine clinic when appropriate,” said Dr. Gilyadov, who wasn’t involved in the study.
“CBT-I is the first-line treatment for chronic insomnia disorder and can be an effective treatment for most patients. An alternative to CBT-I, when it is not available, is digital CBT-I,” Dr. Gilyadov said.
“There are also behavioral therapies called BBT-I [brief behavioral treatment for insomnia] and ACT [acceptance and commitment therapy]. These are therapies that may be offered by psychologists who specialize in the treatment of chronic insomnia disorder,” Dr. Gilyadov noted.
The study was conducted in collaboration with medXcloud and funded by ResMed. Dr. Benjafield is an employee of ResMed. Dr. Gilyadov had no relevant disclosures.

FROM SLEEP 2024
Better Sleep Tied to Less Loneliness
HOUSTON — Sleep may have a role in driving down rates of loneliness, especially among younger adults.
A study of nearly 2300 participants showed that better sleep health is associated with significantly lower levels of loneliness across ages and that the association is particularly strong in younger individuals.
The US Surgeon General has identified loneliness as “a major public health concern, linked to high rates of negative physical and mental health outcomes,” lead researcher Joseph Dzierzewski, PhD, vice president for research and scientific affairs at the National Sleep Foundation, told this news organization.
“Loneliness is an urgent public health crisis, and there is a pressing need for providers to better understand and treat it,” Dr. Dzierzewski said in a statement.
“Better sleep health might be connected to lower feelings of loneliness by empowering people to engage in social activities, reducing feelings of negative emotions and increasing the likelihood that people interpret interactions in a positive way,” he added.
The findings were presented at SLEEP 2024: 38th Annual Meeting of the Associated Professional Sleep Societies and recently published in an online supplement of the journal Sleep.
Rested, Connected
An American Psychiatric Association poll conducted earlier this year showed 30% of US adults reported feelings of loneliness at least once a week over the past year, and 10% reported feeling lonely every day.
Younger people are more likely to report feeling lonely, with 30% of Americans, aged 18-34 years, feeling lonely every day or several times a week.
While there is growing research identifying a relationship between loneliness and poor sleep in different age groups, few studies have explored ties between social and emotional loneliness and sleep health across the adult lifespan.
In the current study led by Dr. Dzierzewski, 2297 adults (mean age, 44 years; 51% male) completed a validated sleep health questionnaire and loneliness scale.
Linear regression analyses were used to examine the direct associations between sleep health, age, and loneliness. Moderation analyses tested whether the link between sleep health and loneliness differed by age.
On average, the total sleep score was 7.7 (range, 0-12), with higher scores indicating better multidimensional sleep health, and total loneliness scale score was 8.9 (out of 11), indicating moderate levels of loneliness.
Better sleep health and younger age were associated with significantly lower loneliness total scores and social and emotional loneliness subscale scores (all P < .001).
Age significantly moderated the association between sleep health and total (P < .001) and emotional loneliness scores (P < .001) but did not moderate the association between sleep health and social loneliness (P = .034). Better sleep health was associated with lower loneliness across ages, and this association was stronger at younger ages.
“Why younger adults might experience more sleep-related benefits to loneliness than older adults is unknown and intriguing — certainly worth further investigation,” Dr. Dzierzewski said in a conference statement.
Untapped Avenue
Promoting sleep health may be an “untapped avenue” to support efforts and programs that aim to reduce loneliness and increase engagement in all age groups but especially in younger ages, the researchers noted.
Future research should consider monitoring sleep health in programs or interventions that address loneliness, they added.
“Healthcare providers should be aware of the important link between sleep health and loneliness as both sleep and social connections are essential to health and well-being. When sitting across from patients, asking about both sleep health and loneliness might yield important insights into avenues for health promotion,” said Dr. Dzierzewski.
Michael Breus, PhD, clinical psychologist and founder of SleepDoctor.com, who wasn’t involved in the study, is not surprised by the results.
It makes sense that better sleep would lead to less feelings of loneliness, he told this news organization.
Research has shown that when someone is not sleeping well, they “give others a sense of unhappiness, which socially deflects new encounters or even encounters with friends. So social awareness and social initiation would appear to both be affected by sleep quality, therefore potentially leading, at least in part, to loneliness,” he said.
Support for the study was provided by the National Institute on Aging. Dr. Dzierzewski and Dr. Breus had no relevant disclosures.

HOUSTON — Sleep may have a role in driving down rates of loneliness, especially among younger adults.
A study of nearly 2300 participants showed that better sleep health is associated with significantly lower levels of loneliness across ages and that the association is particularly strong in younger individuals.
The US Surgeon General has identified loneliness as “a major public health concern, linked to high rates of negative physical and mental health outcomes,” lead researcher Joseph Dzierzewski, PhD, vice president for research and scientific affairs at the National Sleep Foundation, told this news organization.
“Loneliness is an urgent public health crisis, and there is a pressing need for providers to better understand and treat it,” Dr. Dzierzewski said in a statement.
“Better sleep health might be connected to lower feelings of loneliness by empowering people to engage in social activities, reducing feelings of negative emotions and increasing the likelihood that people interpret interactions in a positive way,” he added.
The findings were presented at SLEEP 2024: 38th Annual Meeting of the Associated Professional Sleep Societies and recently published in an online supplement of the journal Sleep.
Rested, Connected
An American Psychiatric Association poll conducted earlier this year showed 30% of US adults reported feelings of loneliness at least once a week over the past year, and 10% reported feeling lonely every day.
Younger people are more likely to report feeling lonely, with 30% of Americans, aged 18-34 years, feeling lonely every day or several times a week.
While there is growing research identifying a relationship between loneliness and poor sleep in different age groups, few studies have explored ties between social and emotional loneliness and sleep health across the adult lifespan.
In the current study led by Dr. Dzierzewski, 2297 adults (mean age, 44 years; 51% male) completed a validated sleep health questionnaire and loneliness scale.
Linear regression analyses were used to examine the direct associations between sleep health, age, and loneliness. Moderation analyses tested whether the link between sleep health and loneliness differed by age.
On average, the total sleep score was 7.7 (range, 0-12), with higher scores indicating better multidimensional sleep health, and total loneliness scale score was 8.9 (out of 11), indicating moderate levels of loneliness.

Solving Restless Legs: Largest Genetic Study to Date May Help
For decades, scientists have been trying to unravel the mysteries of restless legs syndrome (RLS), a poorly understood and underdiagnosed neurological disorder causing itching, crawling, and aching sensations in the limbs that can only be relieved with movement.
A sweeping new genetic study, coauthored by an international team of 70 — including the world’s leading RLS experts — marks a significant advance in that pursuit. Published in Nature Genetics, it is the largest genetic study of the disease to date.
“It’s a huge step forward for patients as well as the scientific community,” said lead author Juliane Winkelmann, MD, a neurologist and geneticist with the Technical University of Munich, Munich, Germany, who’s been studying and treating patients with RLS for 30 years. “We believe it will allow us to better predict the likelihood of developing RLS and investigate new ways to prevent and modify it.”
The common condition, affecting about 1 in 10 adults, was first described centuries ago — by English physician Thomas Willis in the late 1600s. And while we know a lot more about it today — it’s familial in about half of all patients and has been linked to iron deficiency, among other conditions — its exact cause remains unknown.
With preferred drugs long prescribed to quell symptoms shown in recent years to actually worsen the disorder over time, doctors and patients are hungry for alternatives to treat or prevent the sleep-sabotaging condition.
“The main treatments that everybody continues to use are actually making people worse,” said Andrew Berkowski, MD, a Michigan-based neurologist and RLS specialist not involved in the study. These drugs — dopamine agonists such as levodopa and pramipexole — can also potentially cause drug dependence, Dr. Berkowski said.
How This Could Lead to New Treatments
In the new study, the group analyzed three genome-wide association studies, collectively including genetic information from 116,647 patients with RLS and more than 1.5 million people without it.
They identified 161 gene regions believed to contribute to RLS, about a dozen of which are already targets for existing drugs for other conditions. Previously, scientists knew of only 22 associated genes.
“It’s useful in that it identifies new genes we haven’t looked at yet and reinforces the science behind some of the older genes,” said Dr. Berkowski. “It’s given us some ideas for different things we should look into more closely.”
Among the top candidates are genes that influence glutamate — a key chemical messenger that helps move signals between nerve cells in the brain.
Several anticonvulsant and antiseizure drugs, including perampanel, lamotrigine, and gabapentin, target glutamate receptors. And at least one small study has shown perampanel prescribed off-label can improve RLS symptoms.
“Compared to starting at the beginning and developing an entirely new chemical entity, we could run clinical trials using these alternatives in RLS patients,” said the study’s first author, Steven Bell, PhD, an epidemiologist with the University of Cambridge, Cambridge, England.
The study also confirmed the MIES1 gene, which is related to dopamine expression and iron homeostasis, as a key genetic contributor to RLS risk. Low levels of iron in the blood have long been thought to trigger RLS.
The Role of Gene-Environment Interactions
Through additional data analysis, the team confirmed that many of the genes associated with RLS play a role in development of the central nervous system.
“This strongly supports the hypothesis that restless legs syndrome is a neurodevelopmental disorder that develops during the embryo stage but doesn’t clinically manifest until later in life,” said Dr. Winkelmann.
About half of people with RLS report some family history of it.
But not all with a genetic predisposition will develop symptoms.
For instance, the study found that while the same gene regions seem to be associated with risk in both men and women, in practice, RLS is twice as common among women. This suggests that something about women’s lives — menstruation, childbirth, metabolism — may switch a preexisting risk into a reality.
“We know that genetic factors play an important role in making people susceptible to the disease,” said Dr. Winkelmann, “but in the end, it is the interaction between genetic and environmental factors that may lead to its manifestation.”
The study also found associations between RLS and depression and suggests that RLS may increase the risk for type 2 diabetes.
Improving RLS Care
A potentially useful tool coming out of the study was a “polygenic risk score,” which the researchers developed based on the genes identified. When they tested how accurately the score could predict whether someone would develop RLS within the next 5 years, the model got it right about 90% of the time.
Dr. Winkelmann imagines a day when someone could use such a polygenic risk score to flag the high risk for RLS early enough to take action to try to prevent it. More research is necessary to determine precisely what that action would be.
As for treatments, Dr. Berkowski thinks it’s unlikely that doctors will suddenly begin using existing, glutamate-targeting drugs off-label to treat RLS, as many are prohibitively expensive and wouldn’t be covered by insurance. But he’s optimistic that the study can spawn new research that could ultimately help fill the treatment gap.
Shalini Paruthi, MD, an adjunct professor at Saint Louis University, St. Louis, Missouri, and chair of the Restless Legs Syndrome Foundation’s board of directors, sees another benefit.
“The associations found in this study between RLS and other medical disorders may help patients and their physicians take RLS more seriously,” Dr. Paruthi said, “as treating RLS can lead to multiple other downstream improvements in their health.”
