Randomized Controlled Trial Multicenter StudyAssociation between blood glucose levels the next day following targeted temperature initiation and outcome in traumatic brain injury: a post-hoc analysis of the B-HYPO study.
We investigated associations between blood glucose levels and clinical outcomes in participants of the multi-center randomized controlled Brain-Hypothermia (B-HYPO) study. Patients with severe traumatic brain injury (TBI, Glasgow Coma Scale 4-8) were assigned to therapeutic hypothermia (TH, 32-34°C, n = 98) or fever control (35.5-37.0°C, n = 50) groups. TH patients were cooled as soon as possible for ≥72 h and rewarmed at a rate of <1°C/d. ⋯ In the TH group, the initial stress hyperglycemia was sustained the next day after TH induction. Day 1 BG predicted outcome in TBI patients with TH and fever control. Our findings indicate the significance of BG control particularly during TH treatment.

Multicenter Study Comparative Study
Predicting Recovery Patterns After Sport-Related Concussion.
Clinicians sometimes treat concussed individuals who have amnesia, loss of consciousness (LOC), a concussion history, or certain symptom types more conservatively, but it is unclear whether recovery patterns differ in individuals with these characteristics. ⋯ Athletes who experienced amnesia had more symptoms and greater deficits in cognition and balance. Symptoms and cognitive or balance deficits were not consistently associated with LOC or concussion history. Acute symptoms had a strong influence on balance scores and, to a lesser extent, on cognition. However, we found no evidence to support more cautious return-to-play decisions for athletes with these characteristics, as group recovery occurred within normal timelines. Our study supports current clinical practice: recommending that athletes be withheld from activity until they are asymptomatic, followed by a graduated return-to-play progression.

Multicenter StudyNeuro, trauma, or med/surg intensive care unit: Does it matter where multiple injuries patients with traumatic brain injury are admitted? Secondary analysis of the American Association for the Surgery of Trauma Multi-Institutional Trials Committee decompressive craniectomy study.
Patients with nontraumatic acute intracranial pathology benefit from neurointensivist care. Similarly, trauma patients with and without traumatic brain injury (TBI) fare better when treated by a dedicated trauma team. No study has yet evaluated the role of specialized neurocritical (NICU) and trauma intensive care units (TICU) in the management of TBI patients, and it remains unclear which TBI patients are best served in NICU, TICU, or general (Med/Surg) ICU. ⋯ Therapeutic study, level IV.

Increased peri-operative crystalloid transfusion is associated with better outcomes after spontaneous hypertensive putamen hemorrhage: A retrospective study.
The appropriate amount of transfused fluids, and which types of fluids should be transfused during the peri-operative period, is a matter of controversy among neurosurgeons. Thus, a retrospective study was conducted to assess whether crystalloid transfusion is associated with better outcomes after spontaneous hypertensive putamen hemorrhage (HPH). ⋯ Increased perioperative crystalloid transfusion was independently associated with better outcome across a spectrum of surgical risk profiles after spontaneous HPH.

Multicenter StudyHypoaminoacidemia characterizes chronic traumatic brain injury.
Individuals with a history of traumatic brain injury (TBI) are at increased risk for a number of disorders, including Alzheimer's disease, Parkinson's disease, and chronic traumatic encephalopathy. However, mediators of the long-term morbidity are uncertain. We conducted a multi-site, prospective trial in chronic TBI patients (∼18 years post-TBI) living in long-term 24-h care environments and local controls without a history of head injury. ⋯ Many years after injury, TBI patients exhibit abnormal metabolic responses and altered relationships between circulating amino acids, cytokines, and hormones. This pattern is consistent with TBI, inducing a chronic disease state in patients. Understanding the mechanisms causing the chronic disease state could lead to new treatments for its prevention.
