ADVOCATE WATCH

Brief (<4 hour) sleep episodes are insufficient for restoring performance in first-year resident physicians working overnight extended-duration work shifts
SLEEP
February 22, 2019

From the abstract's study objectives: "The Accreditation Council for Graduate Medical Education (ACGME) recently reinstated extended-duration (24-28 hour) work shifts (EDWS) for postgraduate year 1 (PGY-1) resident physicians. This study examined the relationship between overnight sleep duration during EDWS and subsequent ‘post-call’ performance in PGY-1 resident physicians."

Takeaway: The results shouldn't be surprising to healthcare professionals who work in the field of sleep, but will the medical establishment in general pay any attention to this data when it comes to crafting healthy work shifts and time off periods for its workers? Sometimes "advocacy begins at home."

CULTURE WATCH

Ad libitum Weekend Recovery Sleep Fails to Prevent Metabolic Dysregulation during a Repeating Pattern of Insufficient Sleep and Weekend Recovery Sleep
CURRENT BIOLOGY
February 19, 2019

From the research study: “Obtaining extra sleep during the weekend is a common self-selected strategy used to recover from sleep loss incurred during the workweek. Yet the influence of weekend recovery sleep on metabolic dysregulation associated with insufficient sleep, and specifically recurrent insufficient sleep following the weekend, is poorly understood. Thus, our primary aims were to investigate how ad libitum weekend recovery sleep impacts circadian timing, energy intake, body weight, and insulin sensitivity during recurrent insufficient sleep following ad libitum weekend recovery sleep. Our findings show that energy intake from after-dinner snacks and body weight were increased, and insulin sensitivity was reduced during recurrent insufficient sleep following ad libitum weekend recovery sleep. Furthermore, during recurrent insufficient sleep following weekend recovery sleep, we show that the timing of the internal circadian clock was delayed, and hepatic and muscle insulin sensitivity were reduced. Our findings suggest that benefits of weekend recovery sleep are transient, and they identify lower hepatic and muscle insulin sensitivity and delayed circadian timing as potential negative consequences associated with weekend recovery sleep followed by recurrent insufficient sleep.

Takeaway: Or, in 10 words: Sleeping in on Saturday does not pay off sleep debt.

INDUSTRY WATCH

Diagnosing Obstructive Sleep Apnea: The Glass is Half Empty, Despite What You've Been Told
MEDSCAPE
February 27, 2019

From the commentary: "Believe it or not, the sleep medicine field still can't figure out how to diagnose obstructive sleep apnea."

Takeaway: Wait…What? Sorry to say, comments are already closed on this commentary (after only three were published). But please go read the piece anyway and see if you agree with this doctor's assessment of hypopnea-counting for AHI and whether people with mild OSA actually need therapy. 

TREND WATCH

Rear View Safety RVS-335 iVue Driver Fatigue System
SLEEP REVIEW
February 27, 2019

From the article: “Brooklyn-based company Rear View Safety will showcase a variety of 2019 safety products at the 2019 NTEA Work Truck Show March 5-7 in Indianapolis.” 

Takeaway: Sleep trackers and wearables get a lot of hype, but research for better devices to handle driver fatigue for transportation and industrial workers is equally active and may even be more promising. 

TECHNOLOGY WATCH

Oura Sleep Analysis Ring: Heaps of Hype, Little Utility—The Skeptical Cardiologist reviews the latest wearable
MEDPAGE TODAY NEUROLOGY
March 3, 2019

From the product review: A quick look at the Oura web site certainly conveys the sense that this is the slickest, most cutting-edge personal wearable sleep and activity tracker one could purchase. …However, despite Oura's tantalizing claims, there is only one legitimate scientific comparison of the ring to the gold-standard of sleep evaluation, polysomnography (PSG). This was published by SRI International researchers in 2017 in Behavior Sleep Medicine. Its full contents can be read here.

Takeaway: If there's only one study that's shown any kind of cross-comparison to the gold-standard NPSG—and it's 2 years oldit would be in the manufacturer's best interest to run more tests to prove out its product's accuracy. But more testing costs money; I doubt they will borrow from the deep advertising budget to pay for more proof of concept when consumers seem unconcerned about it.

PHARMA WATCH

Can plants and herbs play a role in sleep medicine?
SLEEP JUNKIES
February 19, 2019

From the podcast: “Dr. Josh Corn is a licensed naturopathic doctor and in this episode he tells us about the types of herbs and supplements he uses to treat patients he sees with sleep issues.
Dr. Corn works as a primary care provider in the state of Oregon and graduated from National University of Natural Medicine, the oldest accredited naturopathic medical university in North America and a leader in natural medicine education and evidence-based research.” 

Takeaway: Are natural approaches to insomnia the opposite side of the same coin? 

HEALTH LITERACY WATCH

Evening Exercise Will Not Ruin Sleep
SLEEP REVIEW
February 21, 2019

From the article: “The standing belief that high-intensity exercise should be avoided in the early evening due to its effect on sleep acts as a barrier for some people who might otherwise fit exercise into their busy schedules. …But new research published in Experimental Physiology suggests that 30 minutes of high-intensity exercise performed in the early evening does not negatively affect subsequent sleep, and may also reduce feelings of hunger.”

Takeaway: As a former night gym rat, I always wondered why I could sleep just fine after an evening work out. This new research suggests it's not a circadian rhythm busting, sleep hygiene shredding practice as previously thought.

LEGISLATION WATCH

Nurses, Social Workers Demand Action on Workplace Violence: "Where we are today isn't good enough"
MEDPAGE TODAY
February 28, 2019

From the article: “[Rep. Joe Courtney]'s bill would mandate that OSHA create a national standard requiring health care and social service employers to develop and execute comprehensive workplace violence prevention plans.

[House Education and Labor Committee's Workforce Protections subcommittee chairwoman Rep. Alma Adams] explained that such a plan 'would identify risks, specify both work practice and environmental controls, and require training, reporting and incident investigation.'
 
It would also require employers to keep a log of violent incidents and prepare annual summaries. In addition, the bill would expand protections to public employees in the 24 states that are currently not covered by OSHA by forcing compliance from any healthcare institutions and social service agencies that receive Medicare funds.
 
Finally, the bill calls for OSHA to meet strict deadlines. The agency would be required to publish an interim final standard within 1 year of enactment and a final standard within 42 months of its enactment.
 
'These are not radical, impractical, infeasible or unaffordable requirements," said Adams.” 

Takeaway: These efforts will make the workplace safer for sleep techs and their patients, as well.
