The impact of the COVID-19 pandemic on sleep medicine practices. Journal of clinical sleep medicine : JCSM : official publication of the American Academy of Sleep Medicine Johnson, K. G., Sullivan, S. S., Nti, A., Rastegar, V., Gurubhagavatula, I. 2021; 17 (1): 79?87
Abstract

The COVID-19 pandemic required sleep centers to consider and implement infection control strategies to mitigate viral transmission to patients and staff. Our aim was to assess measures taken by sleep centers due to the COVID-19 pandemic and plans surrounding reinstatement of sleep services.We distributed an anonymous online survey to health care providers in sleep medicine on April 29, 2020. From responders, we identified a subset of unique centers by region and demographic variables.We obtained 379 individual responses, which represented 297 unique centers. A total of 93.6% of unique centers reported stopping all or nearly all sleep testing of at least one type, without significant differences between adult and pediatric labs, geographic region, or surrounding population density. By contrast, a greater proportion of respondents continued home sleep apnea testing services. A total of 60.3% reduced home sleep apnea testing volume by at least 90%, compared to 90.4% that reduced in-laboratory testing by at least 90%. Respondents acknowledged that they implemented a wide variety of mitigation strategies. While no respondents reported virtual visits to be ? 25% of clinical visits prior to the pandemic, more than half (51.9%) anticipated maintaining ? 25% virtual visits after the pandemic.Among surveyed sleep centers, the vast majority reported near-cessation of in-laboratory sleep studies, while a smaller proportion reported reductions in home sleep apnea tests. A large increase in the use of telemedicine was reported, with the majority of respondents expecting the use of telehealth to endure in the future.

Abstract

None: The last several years have seen intense debate about the issue of transitioning between standard and daylight saving time. In the United States, the annual advance to daylight saving time in spring, and fall back to standard time in autumn, is required by law (although some exceptions are allowed under the statute). An abundance of accumulated evidence indicates that the acute transition from standard time to daylight saving time incurs significant public health and safety risks, including increased risk of adverse cardiovascular events, mood disorders, and motor vehicle crashes. Although chronic effects of remaining in daylight saving time year-round have not been well studied, daylight saving time is less aligned with human circadian biology - which, due to the impacts of the delayed natural light/dark cycle on human activity, could result in circadian misalignment, which has been associated in some studies with increased cardiovascular disease risk, metabolic syndrome and other health risks. It is, therefore, the position of the American Academy of Sleep Medicine that these seasonal time changes should be abolished in favor of a fixed, national, year-round standard time.

Sleep medicine exposure offered by United States residency training programs. Journal of clinical sleep medicine : JCSM : official publication of the American Academy of Sleep Medicine Sullivan, S. S., Cao, M. T. 2020
Abstract

To understand the sleep medicine (SM) educational exposure among parent specialties of sleep medicine fellowships, we conducted an online survey among ACGME-approved training programs.Target respondents were program directors of family medicine, otolaryngology, psychiatry, neurology, pediatrics, and pulmonary and critical care (PCCM) training programs in the United States. The survey was based on the Sleep Education Survey (SES), a peer-reviewed, published survey created by the American Academy of Neurology Sleep Section. The modified 18-question survey was emailed via Survey Monkey per published methods totaling 3 requests approximately one week apart in January 2017.A total of 1,228 programs were contacted, and 479 responses were received for an overall response rate of 39%. Some programs in every specialty group offered a SM elective or a required rotation to trainees. PCCM and neurology reported the highest percentages of SM rotation as an option for housestaff (85.7% and 90.8%, respectively), and PCCM had the highest portion of programs indicating a rotation requirement (75.4%). Teaching format was a mixture of didactic lectures, sleep center/lab exposure, and case reports; with lectures being the most common format. Didactics averaged 4.75 hours per year. Few programs reported trainees subsequently pursuing SM fellowship (< 10% produced a fellow over five years), and even fewer reported having a trainee who pursued grant funding for sleep-related research over five years.There is wide variability and overall low exposure to sleep medicine education among United States "parent" ACGME training programs whose medical boards offer sleep medicine certification.

Sleep-Disordered Breathing, Orofacial Growth, and Prevention of Obstructive Sleep Apnea. Sleep medicine clinics Guilleminault, C., Sullivan, S. S., Huang, Y. 2019; 14 (1): 13?20
Abstract

Abnormal breathing during sleep is related to intrinsic and extrinsic factors that are present early in life. Investigation of fetal development and early-in-life orofacial growth allows recognition of risk factors that lead to change in upper airway patency, which leads to abnormal upper airway resistance, abnormal inspiratory efforts, and further increase in resistance and progressive narrowing of the collapsible upper airway. Such evolution can be recognized by appropriate clinical evaluation, specific polysomnographic patterns, and orofacial imaging. Recognition of the problems should lead to appropriate treatments and prevention of obstructive sleep apnea and its comorbidities.

Management of Obstructive Sleep Apnea in Commercial Motor Vehicle Operators: Recommendations of the AASM Sleep and Transportation Safety Awareness Task Force JOURNAL OF CLINICAL SLEEP MEDICINE Gurubhagavatula, I., Sullivan, S., Meoli, A., Patil, S., Olson, R., Berneking, M., Watson, N. F. 2017; 13 (5): 745?58
Abstract

The American Academy of Sleep Medicine Sleep and Transportation Safety Awareness Task Force responded to the Federal Motor Carrier Safety Administration and Federal Railroad Administration Advance Notice of Proposed Rulemaking and request for public comments regarding the evaluation of safety-sensitive personnel for moderate-to-severe obstructive sleep apnea (OSA). The following document represents this response. The most salient points provided in our comments are that (1) moderate-to-severe OSA is common among commercial motor vehicle operators (CMVOs) and contributes to an increased risk of crashes; (2) objective screening methods are available and preferred for identifying at-risk drivers, with the most commonly used indicator being body mass index; (3) treatment in the form of continuous positive airway pressure (CPAP) is effective and reduces crashes; (4) CPAP is economically viable; (5) guidelines are available to assist medical examiners in determining whether CMVOs with moderate-to-severe OSA should continue to work without restrictions, with conditional certification, or be disqualified from operating commercial motor vehicles.

Mouth breathing, "nasal disuse," and pediatric sleep-disordered breathing SLEEP AND BREATHING Lee, S., Guilleminault, C., Chiu, H., Sullivan, S. S. 2015; 19 (4): 1257-1264
Abstract

Adenotonsillectomy (T&A) may not completely eliminate sleep-disordered breathing (SDB), and residual SDB can result in progressive worsening of abnormal breathing during sleep. Persistence of mouth breathing post-T&As plays a role in progressive worsening through an increase of upper airway resistance during sleep with secondary impact on orofacial growth.Retrospective study on non-overweight and non-syndromic prepubertal children with SDB treated by T&A with pre- and post-surgery clinical and polysomnographic (PSG) evaluations including systematic monitoring of mouth breathing (initial cohort). All children with mouth breathing were then referred for myofunctional treatment (MFT), with clinical follow-up 6�months later and PSG 1�year post-surgery. Only a limited subgroup followed the recommendations to undergo MFT with subsequent PSG (follow-up subgroup).Sixty-four prepubertal children meeting inclusion criteria for the initial cohort were investigated. There was significant symptomatic improvement in all children post-T&A, but 26 children had residual SDB with an AHI?>?1.5 events/hour and 35 children (including the previous 26) had evidence of "mouth breathing" during sleep as defined [minimum of 44�% and a maximum of 100�% of total sleep time, mean 69?�?11�% "mouth breather" subgroup and mean 4?�?3.9�%, range 0 and 10.3�% "non-mouth breathers"]. Eighteen children (follow-up cohort), all in the "mouth breathing" group, were investigated at 1�year follow-up with only nine having undergone 6�months of MFT. The non- MFT subjects were significantly worse than the MFT-treated cohort. MFT led to normalization of clinical and PSG findings.Assessment of mouth breathing during sleep should be systematically performed post-T&A and the persistence of mouth breathing should be treated with MFT.

Emerging drugs for common conditions of sleepiness: obstructive sleep apnea and narcolepsy EXPERT OPINION ON EMERGING DRUGS Sullivan, S. S., Guilleminault, C. 2015; 20 (4): 571-582
Abstract

Obstructive sleep apnea (OSA) and narcolepsy are sleep disorders associated with high prevalence and high symptomatic burden including prominent sleepiness, daytime dysfunction and poor nocturnal sleep. Both have elevated risk of poor health outcomes. Current therapies are often underutilized, cumbersome, costly or associated with residual symptoms.This review covers current available therapies for OSA and narcolepsy as well as discusses areas for potential drug development, and agents in the therapeutic pipeline, including the cannabinoid dronabinol (OSA), the histamine inverse agonist/ antagonist pitolisant (narcolepsy), and stimulants with uncertain and/or multiple activities such as JZP-110 and JZP-386 (narcolepsy, possibly OSA). Finally it addresses new approaches and uses for therapies currently on the market such as the carbonic anhydrase inhibitor acetazolamide (OSA).Both OSA and narcolepsy are conditions of sleepiness for which lifelong treatments are likely to be required. In OSA, while continuous positive airway pressure will likely remain the gold standard therapy for the foreseeable future, there is plenty of room for integrating phenotypes and variants of OSA into therapeutic strategies to lead to better, more personalized disease modification. In narcolepsy, unlike OSA, drug therapy is the current mainstay of treatment. Advances using novel mechanisms to treat targeted symptoms such as sleepiness and/or novel agents that can treat more than one symptom of narcolepsy, hold promise. However, cost, convenience and side effects remain challenges.

Current Treatment of Selected Pediatric Sleep Disorders NEUROTHERAPEUTICS Sullivan, S. S. 2012; 9 (4): 791-800
Abstract

While pediatric sleep disorders are relatively common, treatments are often not straightforward. There is often a paucity of gold standard studies and data available to guide clinicians, treatments may yield arguably incomplete results, interventions may require chronic use, and/ or involve multiple modalities including behavioral interventions that require high parental and family commitment. This review points out diagnostic differences compared to adults and focuses on current therapy for selected common pediatric sleep disorders including sleep disordered breathing/ obstructive sleep apnea, narcolepsy, and restless legs syndrome. Other common pediatric sleep disorders, such as insomnia and parasomnias, are not covered.

Update on emerging drugs for insomnia EXPERT OPINION ON EMERGING DRUGS Sullivan, S. 2012; 17 (3): 295-298
Abstract

In recent years, there has been no evidence that the problem of chronic insomnia has faded in the least in US adults; on the contrary, a recent estimate of annual lost productivity due to insomnia was $63.2 billion dollars. However, the proportion of insomniacs who are treated continues to be low, indicating the need for continued development and dissemination of effective therapies. Hypnotic drug development has arguably become more focused in recent years, particularly upon the highly anticipated novel target, the orexin (hypocretin) system. Merck's suvorexant (MK-4305) is the first compound of the so-called dual orexin receptor antagonist (DORA) class expected to be submitted for FDA approval, with a new drug application anticipated in 2012. While there has also been some new activity in the modulation of well-characterized targets with well-characterized agents, such as CNS histamine receptors with low-dose doxepin, a decades-old antidepressant and GABA(A) with sublingual zolpidem, experience with melatonin and serotonin modulators suggests that other targets also exist. Diversifying insomnia drug targets may expand possibilities for customizing hypnotic administration to individualized patient presentation and mechanistic underpinnings. In addition, it may offer improved avenues for combining medications with non-drug treatments such as cognitive behavioral therapy for insomnia (CBT-I).

Narcolepsy in adolescents. Adolescent medicine: state of the art reviews Sullivan, S. S. 2010; 21 (3): 542-?
Abstract

Narcolepsy is a disorder of children and adolescence, but until recently it was often not identified until adulthood, with a reported time from onset to diagnosis of about a decade. This disorder affects approximately 0.05% of the population and starts in childhood and adolescence about half of the time. With narcolepsy, the boundaries between wake, sleep, and dreams are blurred. The cardinal features of narcolepsy-cataplexy are daytime somnolence, cataplexy (sometimes occurring long after onset of sleepiness), sleep paralysis, and hypnagogic hallucinations. Weight gain, disturbed nocturnal sleep, and social/school functional changes are common; reactive substance use to maintain wakefulness during the day may also be seen. Males and females are equally affected. It is classically associated with HLA DQB1*0602, the most specific genetic marker for narcolepsy across all ethnic groups. CSF hypocretin has recently been found to be depleted in this disorder, and late-breaking data support that the disease is caused by autoimmune destruction of hypocretin-producing neurons in the hypothalamus. There is no known cure for narcolepsy. Therapies include behavioral/ scheduling modification, medications to combat daytime sleepiness and cataplexy, and treatment of concomitant disorders leading to daytime sleepiness. The differential diagnosis for this disorder should include other disorders of excessive daytime sleepiness with a proclivity toward onset in adolescence, such as delayed sleep phase syndrome, obstructive sleep apnea, and insufficient sleep time; substance use; and less commonly neurologic disorders such as Klein Levin syndrome, Prader-Willi syndrome, and others. Immunomodulator therapy and hypocretin replacement are proposed therapies that hold promise for the future.

Exploring the Electrocardiogram as a Potential Tool to Screen for Premotor Parkinson's Disease MOVEMENT DISORDERS Valappil, R. A., Black, J. E., Broderick, M. J., Carrillo, O., Frenette, E., Sullivan, S. S., Goldman, S. M., Tanner, C. M., Langston, J. W. 2010; 25 (14): 2296-2303
Abstract

The aim of this study was to test the hypothesis that patients with REM sleep behavior disorder, many of whom will develop Parkinson's disease (PD) or a related synucleinopathy, will demonstrate decreased heart rate variability (HRV) compared with a group of age-matched controls as measured by an electrocardiogram during wakefulness. We compared HRV in 11 untreated idiopathic REM sleep behavior disorder patients (9 men and 2 women; mean age, 63.3 years; SD, 7.5 years) and 11 control subjects with idiopathic insomnia without REM sleep behavior disorder (7 men and 4 women; mean age, 59.5 years; SD, 8.7 years). Subjects with other causes of reduced HRV were excluded. HRV was determined from 5-minute presleep segments of a single channel electrocardiogram recorded during polysomnographic evaluations, using R-R intervals during wakefulness. Time domain, geometric measures, and spectral analysis of the R-R intervals were significantly different between cases and controls. A discriminant function analysis correctly classified 95.5% of subjects (overall model fit, P = 0.016). Leave-one-out cross-validation correctly classified 77.3% of subjects. HRV during wakefulness is significantly decreased in patients with idiopathic REM sleep behavior disorder compared with control subjects, suggesting abnormalities of both sympathetic and parasympathetic function. Patients with RBD may later develop motor and cognitive features of a Lewy body disorder, such as PD. Cardiac autonomic dysfunction is also impaired in PD, suggesting that impaired HRV may be an early sign of PD. HRV measured by routine electrocardiograms could be used to screen for Lewy body disorders such as PD.

Insomnia Pharmacology MEDICAL CLINICS OF NORTH AMERICA Sullivan, S. S. 2010; 94 (3): 563-?
Abstract

Insomnia is not only the most common sleep disorder in the population, it is a frequent complaint heard overall by primary care physicians and specialists alike. Given the high prevalence of this disorder, its tendency to persist, and the frequency with which patients complain of symptoms in practice, it is imperative to have an understanding of basic sleep-wake mechanisms and the evolving field of pharmacologic approaches to enhance sleep. Currently, pharmacologic approaches are among the most widely used therapies for insomnia. This article reviews sleep-wake mechanisms, the neuroanatomic targets for sleep and wake-promoting agents, and discusses currently used agents to promote sleep and investigational hypnotics.

Emerging drugs for insomnia: new frontiers for old and novel targets EXPERT OPINION ON EMERGING DRUGS Sullivan, S. S., Guilleminault, C. 2009; 14 (3): 411-422
Abstract

Insomnia is the most prevalent sleep disorder, with up to 50% of the US adult population reporting symptoms of insomnia on a weekly basis and approximately 12% with insomnia disorder. Comorbid conditions such as depression and anxiety are frequent. Insomnia is more common with older age, female gender and socioeconomic status. Traditionally, therapy has focused on GABA(A) receptor agonists, and off-label antidepressant and antihistamine use.With increased understanding of complex neural networks involved in sleep and wake, hypnotics are being developed to target a broader variety of receptors with increasing selectivity. This review summarizes promising compounds in Phase II and III trials with evidence supporting efficacy for treatment of insomnia.5-HT(2A) and 5-HT(2C) antagonists, melatonergic (MT1/MT2) agonists, orexin receptor (OX1/OX2) antagonists, as well as GABA(A) receptor agonists are reviewed and summarized. Data are collected from PubMed and Pharmaprojects database searches, company websites, recent scientific meeting presentations and abstracts.A variety of drugs targeting several pathways, including GABA(A) agonism, MT1/MT2 agonism, 5-HT(2A) antagonism, OX1/OX2 antagonism and others, are in Phase II and III trials. More work should be done to understand the impact of these drugs in certain populations and in the context of comorbid conditions.

Multiple Sleep Latency Test and Maintenance of Wakefulness Test CHEST Sullivan, S. S., Kushida, C. A. 2008; 134 (4): 854-861
Abstract

Excessive daytime sleepiness and fatigue are common complaints in the sleep clinic. The objective evaluation and quantification of these symptoms is important for both the diagnosis of underlying health problems and for gauging treatment response. The multiple sleep latency test measures physiologic sleepiness, whereas the maintenance of wakefulness test (MWT) aims to measure manifest sleepiness. Neither test correlates well with subjective measures of sleep such as the Epworth sleepiness scale and the Stanford sleepiness scale. Although in the past methodological testing differences existed, in 2005 updated practice parameters were published, promoting the standardization of testing procedures. In recent years, there has been an effort to document daytime sleepiness when associated with occupational risk. However, these laboratory-based tests may not reflect or predict real-life experience. Normative data for both tests, particularly the MWT, are limited, and are inadequate for the evaluation of pediatric patients, shift workers, and others.

Nasal obstruction in children with sleep-disordered breathing ANNALS ACADEMY OF MEDICINE SINGAPORE Sullivan, S., Li, K., Guilleminault, C. 2008; 37 (8): 645-648
Abstract

Nasal obstruction secondary to pathological enlargement of inferior nasal turbinates contributes to sleep-disordered breathing (SBD) in prepubertal children, but treatments designed to address turbinate enlargement are often not performed. The aims of these studies are: (1) to appreciate the contribution to SDB of untreated enlarged nasal turbinates in prepubertal children; and (2) to report our experience with treatment of enlarged nasal turbinates in young children with SDB.Children with enlarged nasal turbinates who underwent adenotonsillectomy (T&A) had significantly less improvement in postoperative apnoea-hypopnoea index (AHI) compared to those treated with concomitant turbinate reduction. Children in the untreated turbinate hypertrophy group subsequently underwent radiofrequency ablation of the inferior nasal turbinates; following this procedure, AHI was no different than AHI of those without hypertrophy.In an analysis of safety and effectiveness of radiofrequency treatment of the nasal turbinates, we found the procedure to be a well-tolerated component of SDB treatment.We conclude that radiofrequency (RF) treatment of inferior nasal turbinates is a safe and effective treatment in young prepubertal children with SDB. When indicated, it should be included in the treatment plan for prepubertal children with SDB. However, the duration of effectiveness is variable and therapy may need to be repeated if turbinate hypertrophy recurs.
