Melatonin and Sleep in Preventing Hospitalized Delirium: A Randomized Clinical Trial

Studies suggest that melatonin may prevent delirium, a condition of acute brain dysfunction occurring in 20%-30% of hospitalized older adults that is associated with increased morbidity and mortality. We examined the effect of melatonin on delirium prevention in hospitalized older adults while measuring sleep parameters as a possible underlying mechanism. Methods This was a randomized […]

Sleep-Disordered Breathing in Obese Hospitalized Patients (video)

Sleep-disordered breathing is a common sleep disorder. Recent studies have shown that hospitalized obese patients have a high likelihood of unrecognized sleep-disordered breathing. However, no systematic large study has so far evaluated the outcomes of a screening program. This study provides demographic, clinical, and outcome data from a screening program at a tertiary care academic […]

Short Sleep Duration & Impaired Glycemic Control (video)

Is insomnia linked to poor glycemic control? In this study, people who habitually slept less than seven hours per night had elevated glucose levels, as measured by morning oral glucose tolerance test. In this video, American Journal of Medicine Editor-in-Chief Dr. Joseph Alpert explains the clinical implications of the findings. Read the Research: Habitual and Recent […]

Sleep Duration & Risk for Impaired Glycemic Control (video)

We examined how habitual sleep duration interacts with recent sleep (2 nights) to predict morning oral glucose tolerance test results. We hypothesized that short habitual and recent sleep durations would be additive for poor glucose control. Methods A biracial population of adults (n = 1559) without known diabetes and recruited from the workforce of 2 urban […]

Researchers Find Link between Persistent Insomnia and Increased Mortality Risk

A connection between persistent insomnia and increased inflammation and mortality has been identified by a group of researchers from the University of Arizona. Their study, published in The American Journal of Medicine, found that people who suffer from persistent insomnia are at greater risk than those who experience intermittent insomnia. Although about 20% of U.S. […]
