Importance: Many shift workers have difficulty sleeping during the daytime owing to an inappropriately timed circadian drive for wakefulness.
Objective: To determine whether a dual hypocretin receptor antagonist would enable shift workers to have more daytime sleep.
Design, Setting, And Participants: This double-blind, placebo-controlled randomized clinical trial included 2 weeks of baseline data and 3 weeks of intervention data, from March 2016 to December 2018.
Study Objectives: Nocturnal awakenings may constitute a unique risk for falls among older adults. We describe differences in gait and balance between presleep and midsleep testing, and whether changes in the lighting environment during the midsleep testing further affect gait and balance.
Methods: Twenty-one healthy, late middle-aged and older (64.
Study Objectives: The maternal postpartum period is characterized by sleep fragmentation, which is associated with daytime impairment, mental health disturbances, and changes in melatonin patterns. In addition to sleep fragmentation, women undergo a complex set of physiological and environmental changes upon entering the postpartum period, confounding our understanding of effects of postpartum sleep disturbance. The primary study aim was to understand the basic impact of a single night of postpartum-like sleep fragmentation on sleep architecture, nocturnal melatonin levels, mood, daytime sleepiness, and neurobehavioral performance.

The relations between sleep disturbances and general health and memory among this population are unknown. The current study aimed to replicate the findings that parents of CSHCNs report poorer sleep quality than parents of TD children, and further examine how sleep is related to general health and memory.

They are also susceptible to mood impairments, anxiety, and stress. The current study explored associations between maternal postpartum daily fatigue patterns, which should vary according to circadian influences and mental health.

Our goal was to explore aspects of mothers' nocturnal environments and behaviours that may explain differences in postpartum adjustment. A total of 201 mothers of infants aged 0-6 months completed an online survey with demographics, number and duration of nocturnal awakenings, caretaking behaviours, environment and nocturnal activities during 'one typical night during the past week'.
View Article and Find Full Text PDFPostpartum women have highly disturbed sleep, also known as sleep fragmentation. Fragmentation extends their total sleep period, also disrupting sleep timing. A stable and earlier sleep period among non-postpartum populations is related to better performance, physical health, and mental health.

A rule of thumb has arisen in the sleep field that approximately 5 min of continuous wakefulness are required to form a memory for an awakening. However, few studies have examined memory for these sleep-wake transitions and none have done so in the home, while participants follow their normal routine.

Our goal was to describe the sleep quality and characteristics of college students who use psychostimulant medications nonmedically.
Methods: We surveyed 492 college students about their sleep quality and psychostimulant use characteristics.

Background: Tonsillar hypertrophy contributes to pediatric disorders, including obstructive sleep apnea. The goal was to determine the utility of digital photographs for pediatric tonsillar grading.
Methods: Using Brodsky's grading scale, 41 children (3.
