BACKGROUND In 2011 the U.S. Accreditation Council for Graduate Medical Education began limiting first year resident physicians (interns) to shifts of ≤16 consecutive hours. Controversy persists regarding the effectiveness of this policy for reducing errors and accidents while promoting education and patient care. Using a mathematical model of the effects of circadian rhythms and length of time ...

Previous studies have shown that temporal lobe epilepsy (TLE) involves abnormal structural or functional connectivity in specific brain areas. However, limited comprehensive studies have been conducted on TLE associated changes in the topological organization of structural and functional networks. Additionally, epilepsy is associated with impairment in alertness, a fundamental component of atte...

BACKGROUND/AIMS Little is known about the association of chronic kidney disease (CKD) with sleep quality, mood, and alertness. In this report, we assessed these symptoms among patients with advanced CKD (stages 4-5) and those with end-stage renal disease (ESRD) and compared them to healthy controls without known kidney disease. METHODS Patients were recruited from local dialysis units, outpat...

Chewing has been shown to alleviate feelings of sleepiness and improve cognitive performance during the day. This study investigated the effect of chewing on alertness and cognitive performance across one night without sleep as well as the possible mediating role of cardiac autonomic activity. Fourteen adults participated in a randomized, counterbalanced protocol employing a chewing, placebo an...

electro encephalography is one of the reliable sources to detect sleep onset while driving. in this study we have tried to demonstrate that sleepiness and alertness signals are separable with an appropriate margin by extracting suitable features. so first of all we have recorded eeg signals from 10 volunteers. they were obliged to be sleep deprived about 20 hours before the test. we recorded th...

other employees. We also feel that these should be picked for their neatness, mental alertness, physical condition, age, and conscientious dependability. Much also depends upon the type of patient, his mental capacity, alertness, intelligence and his cooperation. Conceding this, we feel that incidence of infection with modified contagious technique is no greater and possibly even less than in t...

We describe a system for analyzing human driver alertness. It relies on optical flow and color predicates to robustly track a person’s head and facial features. Our system classifies rotation in all viewing directions, detects eye/mouth occlusion, detects eye blinking, and recovers the 3D gaze of the eyes. We show results and discuss how this system can be used for monitoring driver alertness.

BACKGROUND Previous reports have suggested that acupressure is effective in reducing pain and improving sleep quality; however, its effects on alertness have not been characterized. OBJECTIVES The aim of this study was to determine whether two different acupressure treatments have opposing effects on alertness in a full-day classroom setting. DESIGN This was a cross-over (two-treatments; th...
