The Prevalence of Insomnia Subtypes in Relation to Demographic Characteristics, Anxiety, Depression, Alcohol Consumption and Use of Hypnotics
March 24, 2020

From the research summary: “The aim of the present study was to examine the prevalence of insomnia subtypes in relation to several demographic characteristics, as well as to investigate the prevalence of possible anxiety and depression, alcohol consumption and use of hypnotics within the different insomnia subtypes.

Takeaway: Their findings regarding the impact on sleep by alcohol were not what they expected. 


Sleep and Reproductive Health
March 23, 2020

From the research introduction: “Sleep disorders in both men and women are associated with many health problems like depression, hypertension, glucose deregulation, cardiovascular disease, and anxiety disorders and it was reported that sleep disturbances in women coincide with postpartum depression, pregnancy, menopausal transition and premenstrual dysphoria.

Takeaway: This is a thorough overview of the way poor sleep can negatively impact fertility for both males and females.


A laboratory study on the effects of wind turbine noise on sleep: Results of the polysomnographic WiTNES study
March 25, 2020

From the research summary: “Study objectives: Assess the physiologic and self-reported effects of wind turbine noise (WTN) on sleep.

Takeaway: This is the Law of Unintended Consequences, 21st-century version. 


Diagnosis of central disorders of hypersomnolence: A reappraisal by European experts
March 23, 2020

From the clinical review: “We suggest the creation of a new consistent, complaint driven, hierarchical classification for central disorders of hypersomnolence; containing levels of certainty, and giving diagnostic tests, particularly the MSLT, a weighting based on its specificity and sensitivity in the diagnostic context.

Takeaway: This category of sleep disorders remains elusive in the diagnostic arena. Here are some ideas for reframing it for more conclusive diagnoses.


Short-term efficacy of reducing screen media use on physical activity, sleep, and physiological stress in families with children aged 4–14: study protocol for the SCREENS randomized controlled trial
March 23, 2020

From the study protocol: “During the recent decade presence of digital media, especially handheld devices, in everyday life, has been increasing. Survey data suggests that children and adults spend much of their leisure on screen media, including use of social media and video services. Despite much public debate on possible harmful effects of such behavioral shifts, evidence from rigorously conducted randomized controlled trials in free-living settings, investigating the efficacy of reducing screen media use on physical activity, sleep, and physiological stress, is still lacking. Therefore, a family and home-based randomized controlled trial – the SCREENS trial – is being conducted. Here we describe in detail the rationale and protocol of this study.

Takeaway: This is what the beginning of a big study looks like. Should be an interesting process and I'll be curious how much the expected outcome matches the reality.


FDA Accepts NDA for Low-Sodium Alternative to Xyrem for Narcolepsy
March 26, 2020

From the article: “The US Food and Drug Administration (FDA) accepted for filing with Priority Review the Jazz Pharmaceuticals plc’s New Drug Application (NDA) seeking marketing approval for JZP-258, an investigational medicine for the treatment of cataplexy or excessive daytime sleepiness (EDS) in patients 7 years of age and older with narcolepsy.

Takeaway: July 21, 2020 is the goal date for the FDA's final decision.


Inconsistent Bedtime Linked to Increased Cardiovascular Risk
March 25, 2020

From the article: “Researchers at the University of Notre Dame studied the correlation between bedtime regularity and resting heart rate (RHR) and found that individuals going to bed even 30 minutes later than their usual bedtime presented a significantly higher resting heart rate that lasted into the following day.

Takeaway: Granted, this can be a really tricky thing to achieve for nighttime sleep technologists, but it's still a worthwhile goal to promote to all of our patients. 


Overnight Assisted-Living Workers Lose Lawsuit Over Sleep Pay
March 24, 2020

From the article: “A Mid-Atlantic operator of assisted-living residential homes defeated claims brought by employees seeking compensation for time spent sleeping overnight at the facilities, after a Maryland federal judge said sleeping is personal time.

Takeaway: This is a tough one. What about those nighttime caregivers who are there just in case their dementia charges start wandering the halls? Hmmm.
