The objective of this pilot study was to evaluate the effects of conjugated estrogens on the rates of cyclic alternating patterns of sleep (CAPS) and nocturnal hot flushes in symptomatic postmenopausal women. Seven postmenopausal or posthysterectomy women aged 45 to 60 years with nocturnal diaphoresis and/or hot flushes participated in this study. The study(More)
A study was conducted at the Tri-State Sleep Disorders Center of Cincinnati, Ohio, to evaluate both quantitative and qualitative daily function and productivity outcomes of treating obstructive sleep apnea (OSA) with nasal continuous positive airway pressure (NCPAP). This was a prospective outcome study conducted in 316 patients with diagnosed and treated(More)
OBJECTIVE Fibromyalgia (FM) is associated with the sleep phenomenon of alpha intrusion, and with low growth hormone secretion. Sodium oxybate has been shown to increase both slow-wave sleep and growth hormone levels. This double blind, randomized, placebo controlled crossover trial was conducted to evaluate the effects of sodium oxybate on the subjective(More)
An automated positive airway pressure device that monitors respiratory patterns and provides dynamic, real-time, relational pressure has been developed for the treatment of obstructive sleep apnea (OSA). The purpose of this study was to compare self-adjusting pressure to classical nasal continuous positive airway pressure (NCPAP). Subjects were newly(More)
OBJECTIVE To evaluate the effects of using a gamma-hydroxybutyrate (GHB) administered in divided doses at night in 11 patients previously diagnosed with fibromyalgia (FM). METHODS Subjects completed daily diaries assessing their pain and fatigue levels and slept in the sleep laboratory before and one month after initiating GHB treatment. Polysomnographic(More)
A study was conducted to polysomnographically evaluate the effects of external nasal dilation on sleep quality in mild snorers by examining the amount of sleep fragmentation and cyclic alternating pattern sequences (CAPS) rates. A two-night, open-label, one-way crossover polysomnographic evaluation, with and without use of an external nasal dilator, was(More)
Addresses the socialization process among marketing doctoral students. Four modes of doctoral student socialization are provided from depth interviews conducted with 28 purposively selected individuals. These four modes are based upon two characteristics: degree of program structure, or formal socialization; and degree of student-faculty interaction, or(More)
BACKGROUND We recently demonstrated that the use of an external nasal dilator reduced subjective snoring levels and improved sleep quality. Our study polysomnographically evaluated the effects of this device on the frequency of obstructive airway events during sleep in infants with and without congestion. METHODS We used a crossover study to monitor 20(More)
The standard methods of scoring sleep patterns do not ensure an accurate clinical impression of sleep quality. This is important especially in depressed insomniacs because persistent poor sleep increases the likelihood of recurrent depressive episodes. Changes in cyclic alternating patterns (CAP) in sleep have been shown to reflect corresponding changes in(More)
The comparative effects of sleep patterns and rates of cyclic alternating patterns (CAP rate) in a high quality innerspring mattress were compared to those on a unique foam support mattress in 10 normal subjects. Results showed no differences in sleep stages, number of wakes, or total sleep time between the two conditions. CAP rates were significantly(More)
