Background: Physiological functions with circadian rhythmicity are often disrupted during illness., Objective: To assess the utility of circadian rhythmicity of vital signs in predicting outcome of traumatic brain injury (TBI)., Methods: A retrospective single-center cohort study of adult intensive care unit (ICU) patients with largely isolated TBI to explore the relationship between the circadian rhythmicity of vital signs during the last 24 hours before ICU discharge and clinical markers of TBI severity and score on the Glasgow Outcome Scale 6 months after injury (GOS-6)., Results: The 130 study participants had a median age of 39.0 years (IQR, 23.0-59.0 years), a median Glasgow Coma Scale score at the scene of 8.0 (IQR, 3.0-13.0), and a median Rotterdam score on computed tomography of the head of 3 (IQR, 3-3), with 105 patients (80.8%) surviving to hospital discharge. Rhythmicity was present for heart rate (30.8% of patients), systolic blood pressure (26.2%), diastolic blood pressure (20.0%), and body temperature (26.9%). Independent predictors of a dichotomized GOS-6 ≥4 were the Rotterdam score (odds ratio [OR], 0.38 [95% CI, 0.18-0.81]; P = .01), Glasgow Coma Scale score at the scene (OR, 1.22 [95% CI, 1.05-1.41]; P = .008), age (OR, 0.95 [95% CI, 0.92-0.98]; P = .003), oxygen saturation <90% in the first 24 hours (OR, 0.19 [95% CI, 0.05-0.73]; P = .02), serum sodium level <130 mmol/L (OR, 0.20 [95% CI, 0.05-0.70]; P = .01), and active intracranial pressure management (OR, 0.16 [95% CI, 0.04-0.62]; P = .008), but not rhythmicity of any vital sign., Conclusion: Circadian rhythmicity of vital signs at ICU discharge is not predictive of GOS-6 in patients with TBI., (©2022 American Association of Critical-Care Nurses.)

A transient ischemic attack (TIA) significantly increases a person's risk of ischemic stroke. However, little is known about the experiences of these people or what influences their decision to access care. This article explores the stories of three people who experienced a TIA. All participants were interviewed after receiving a diagnosis of TIA by a specialist neurologist. By utilizing a framework of narrative inquiry, several storylines were revealed across temporal, social, and geographical landscapes. The main storylines include: bodily disruption, time stasis, altered temporal perceptions, the roles of others, and help-seeking behavior. The primary author also reflects upon his own origin and explores how this inquiry has influenced his perceptions, career, and nursing practice. This inquiry may assist healthcare workers to gain insight into the experiences of people with TIA and suggests how involvement of significant others is beneficial when educating people at risk of TIA., (© 2015 Wiley Publishing Asia Pty Ltd.)
