Diffusion Tensor Imaging: A Possible Biomarker in Severe Traumatic Brain Injury and Aneurysmal Subarachnoid Hemorrhage?
A great need exists in traumatic brain injury (TBI) and aneurysmal subarachnoid hemorrhage (aSAH) for objective biomarkers to better characterize the disease process and to serve as early endpoints in clinical studies. Diffusion tensor imaging (DTI) has shown promise in TBI, but much less is known about aSAH. ⋯ aSAH, aneurysmal subarachnoid hemorrhageDTI, diffusion tensor imagingFA, fractional anisotropyGOSE, Glasgow Outcome Scale ExtendedTBI, traumatic brain injuryTE, echo timeTR, repetition time.

Observational StudyPsychosocial resiliency is associated with lower emotional distress among dyads of patients and their informal caregivers in the neuroscience intensive care unit.
The purpose of the study is to examine the associations of patients' and their informal caregivers' psychosocial resiliency factors with their own and their partners' emotion domains (distress, anxiety, depression, and anger) after admission to the neuroscience intensive care unit (Neuro-ICU). ⋯ Findings of high distress among both patients and caregivers at admission emphasize the importance of attending to the mental health of both patients and caregivers in the Neuro-ICU. As modifiable psychosocial resiliency factors were associated with emotion domains for both patients and caregivers, interventions to enhance these factors may ameliorate emotional distress among these vulnerable populations.

The objectives of the study are to describe the use of hyperosmolar therapy in pediatric traumatic brain injury (TBI) and examine its effect on intracranial pressure (ICP) and cerebral perfusion pressure (CPP). ⋯ In pediatric TBI with intracranial hypertension, mannitol and 3 % hypertonic saline are commonly used, but dose and therapeutic threshold for use vary without clear indications for one versus another. Controlled trials are warranted, but several barriers were identified, including high exclusion rate, multiple co-interventions, and care variability.

Validation of the Critical-Care Pain Observation Tool in brain-injured critically ill adults.
Pain is a common symptom in the intensive care unit (ICU). Brain-injured patients are often unable to reliably self-report their pain, calling forth the need to use behavioral scales such as the Critical-Care Pain Observation Tool (CPOT). This study aimed to test the reliability and validity of the CPOT use with brain-injured ICU adults. ⋯ Overall, the CPOT use was found to be reliable and valid in this patient group and is new evidence fulfilling an important gap highlighted in the Society of Critical Care Medicine practice guidelines.

There is increasing concern about the possible long-term effects of multiple concussions, particularly on the developing adolescent brain. Whether the effect of multiple concussions is detectable in high school football players has not been well studied, although the public health implications are great in this population. ⋯ In the largest study to date, high school football players with multiple past concussions performed the same on cognitive testing as those with no prior concussions. Concussion history was one of several factors that were independently related to symptom reporting.
