Brief Summary:
Work requirements for medical trainees result in substantial sleep loss. Sleep loss has been associated with increased levels of certain inflammatory hormones that could have negative impact on blood vessel function. The purpose of this study is to determine the effects of sleep loss on blood hormone levels and blood vessel function in medical trainees.
Detailed Description:
Context: Sleep loss is associated with increased blood levels of interleukin-6 (IL-6) and C-reactive protein (CRP). Medical residents are often deprived of normal sleep during extended work shifts, but the effects of work-related sleep loss on biomarkers of vascular inflammation and function are unknown.
Objective: We sought to test the hypothesis that sleep loss during extended work shifts during medical training is associated with increased circulating levels of pro-inflammatory biomarkers and evidence of vascular dysfunction.
Design: Outcome measures were assessed after extended 30-hour work shifts and non-extended 6-hour work shifts in a single-blind, randomized crossover design.
Setting: University hospital medical intensive care unit
Patients or Other Participants: Twenty-two healthy medical residents were studied during a medical intensive care unit rotation.
Main Outcome Measure(s): Sleep related cytokines (interleukin-6 and tumor necrosis factor), serum markers of vascular inflammation (C-reactive protein), and flow-mediated dilation in the brachial artery.
