The growing gap: a study of sleep, encoding, and consolidation of new words in chronic traumatic brain injury.
Evidence from neuroscience emphasizes sleep as a crucial support for longitudinal memory and word learning. In numerous lab-based word learning experiments, participants encode and then retrieve new words within the same session. Single session designs are not adequate for capturing the full word learning process. Single session studies also inhibit exploration of the role of behavioral and lifestyle factors such as sleep in supporting longitudinal word learning. Adults with a history of traumatic brain injury (TBI), who experience challenges in the memory systems that support word learning and report related sleep disturbance, provide a unique opportunity to explore linkages between memory, sleep, and word learning. The purpose of this study was to evaluate longitudinal word learning and the influence of sleep on short- and long-term word recall in 50 adults with chronic moderate-severe traumatic brain injury (TBI) and 50 demographically matched neurotypical peers. Participants took part in the study over a two week period in their homes in an attempt to capture the process of real-world word learning and to measure sleep within normal living conditions. The study found that participants with TBI demonstrated a deficit in word learning that started at encoding, continued across time, and increased over the course of the week. The gap in performance between groups was greater at the 1-week post-test than the immediate post-test. Participants with and without TBI recalled more words when they slept after learning.

Early palliative care consultation offsets hospitalization duration and costs for elderly patients with traumatic brain injuries: insights from a level 1 trauma center.
The purpose of this study was to identify variables and outcomes related to inpatient palliative care (PC) consultation for patients age 65+ with traumatic brain injuries (TBI). The researchers included individuals over age 65 presenting from January 2013-September 2020 with TBI and intracranial hemorrhage. The study found that inpatient PC consultation was uncommon; with only 4% of 576 patients receiving. Features associated with likelihood of consultation were severe TBI and pre-existing dementia. Patients with PC consults had longer overall and intensive care unit (ICU) length of stays (LOS), more days intubated and higher costs. However, those patients with earlier-than-average PC consultation had shorter overall and ICU LOS as well as fewer ventilator days on a ventilator and lower costs. The study concluded that older patients with TBI have a greater likelihood of receiving PC consultation based on pre-existing dementia and severe TBI and patients with PC consultations had worse LOS and higher costs, but those impacts were diminished by earlier involvement from the PC.

Sleep, sleep disorders, and circadian health following mild traumatic brain injury in adults: review and research agenda.
A rapidly expanding scientific literature supports the frequent co-occurrence of sleep and circadian disturbances following mild traumatic brain injury (mTBI). In this paper, the authors review relevant literature and present a research agenda to 1) advance understanding of the reciprocal relationships between sleep and circadian factors and mTBI sequelae and 2) advance rapidly the development of sleep-related treatments in this population.

Safety of antidepressant classes used following traumatic brain injury among Medicare beneficiaries: a retrospective cohort study.
The objective of this study was to compare the risk of several adverse events associated with use of the three most commonly used classes of antidepressants following Traumatic Brain Injury (TBI) in older adults. One of the study’s conclusions was that compared to tricyclic antidepressants, selective serotonin reuptake inhibitor use was associated with increased risk of hemorrhagic stroke.

Race/ethnicity and retention in traumatic brain injury outcomes research: a traumatic brain injury model systems national database study.
The purpose of this study was to investigate the contribution of race/ethnicity to retention in traumatic brain injury (TBI) research at 1 to 2 years postinjury. The findings emphasized the importance of investigating retention rates separately for blacks and Hispanics rather than combining them or grouping either with other races or ethnicities. The results also suggested the need for implementing procedures to increase retention of Hispanics in longitudinal TBI research.

Trend of age-adjusted rates of pediatric traumatic brain injury in U.S. emergency departments from 2006 to 2013.
The objective of this study was to use the 2006(-)2013 Nationwide Emergency Department Sample (NEDS) database to describe trends of age-adjusted rates of pediatric traumatic brain injuries (TBI) treated in U.S. emergency departments. The investigators found that the overall age-adjusted rates of pediatric TBI-related emergency department (ED) visits increased from 2006 to 2013, which was largely caused by pediatric mild TBIs, especially unspecified injury to the head (ICD-9-CM code 959.01) and concussion.

Outcomes of protocolised analgesia and sedation in a neurocritical care unit.
Researchers conducted a retrospective cohort study of 1197 mechanically ventilated patients admitted to a 12-bed neurocritical care unit (NCCU) over four years in order to evaluate the effect of an analgesia-based sedation protocol on medication use and costs in the NCCU. The protocol resulted in increased in fentanyl use and decreased in propofol use, but their findings indicate no effect on healthcare utilization, healthcare costs, or in-hospital mortality. Based on these results, the researchers suggest that similar NCCUs should consider using population-specific protocols to manage analgesia and sedation.

Fever burden and health-related quality of life after intracerebral hemorrhage.
In this prospective observational cohort study, the investigators tested the hypothesis that increased burden of fever is independently associated with decreased health-related quality of life (HRQoL) at follow-up. The authors found that each additional day with a fever was predictive of worse HRQoL domains of Cognitive Function and Mobility after intracerebral hemorrhage up to 1 year. They suggest that HRQoL outcomes may be a sensitive and powerful way to measure the efficacy of fever control in future research.

Sensory sensitivity in operation enduring freedom/operation Iraqi freedom veterans with and without blast exposure and mild traumatic brain injury.
To examine factors associated with noise and light sensitivity among returning Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) Veterans with a self-reported history of mild traumatic brain injury (mTBI) due to blast exposure, the researchers compared the self-report of noise and light sensitivity of 42 OEF/OIF Veterans diagnosed with mTBI resulting from combat blast-exposure to that of 36 blast-exposed OEF/OIF Veterans without a history of mTBI.

Implementation of the Canadian CT Head Rule and Its association with use of computed tomography among patients with head injury.
The researchers evaluated the association of implementation of the Canadian CT Head Rule on head computed tomography (CT) imaging in community emergency departments (EDs). They found that a multicomponent implementation of the Canadian CT Head Rule was associated with a modest reduction in CT use and an increased diagnostic yield of head CTs for adult trauma encounters in community EDs.
