Despite the debilitating consequences and the widespread prevalence of brain trauma insults including spinal cord injury (SCI) and traumatic brain injury (TBI), there are currently few effective therapies for most of brain trauma sequelae. As a consequence, there has been a major quest for identifying better diagnostic tools, predictive models, and directed neurotherapeutic strategies in assessing brain trauma. Among the hallmark features of brain injury pathology is the central nervous systems' (CNS) abnormal activation of the immune response post-injury. ⋯ It is being suggested that there may be an analogy of CNS autoantibodies secretion with the pathophysiology of autoimmune diseases, in which case, understanding and defining the role of autoantibodies in brain injury paradigm (SCI and TBI) may provide a realistic prospect for the development of effective neurotherapy. In this work, we will discuss the accumulating evidence about the appearance of autoantibodies following brain injury insults. Furthermore, we will provide perspectives on their potential roles as pathological components and as candidate markers for detecting and assessing CNS injury.

Trends and outcome predictors after traumatic brain injury surgery: a nationwide population-based study in Taiwan.
The authors sought to analyze trends in hospital resource utilization and mortality rates in a population of patients who had received traumatic brain injury (TBI) surgery. ⋯ These data reveal an increased prevalence of TBI, especially in older patients, and an increased hospital treatment cost but a decreased in-hospital mortality rate. Health care providers and patients should recognize that attributes of the patient and of the hospital may affect hospital resource utilization and the mortality rate. These results are relevant not only to other countries with similar population sizes but also to countries with larger populations.

Cognitive and behavioural post-traumatic impairments: what is the specificity of a brain injury ? A study within the ESPARR cohort.
The variety and extent of impairments occurring after traumatic brain injury vary according to the nature and severity of the lesions. In order to better understand their interactions and long-term outcome, we have studied and compared the cognitive and neurobehavioral profile one year post onset of patients with and without traumatic brain injury in a cohort of motor vehicle accident victims. ⋯ The presence and the initial severity of a traumatic brain injury condition the nature and frequency of residual effects after one year. Some impairments such as irritability, which is generally associated with traumatic brain injury, do not appear to be specific to this population, nor does depressive mood. Substantial interactions between cognitive, affective and neurobehavioral disorders have been highlighted.

In patients with severe traumatic brain injury, increased intracranial pressure (ICP) is associated with poor functional outcome or death. Hypertonic saline (HTS) is a hyperosmolar therapy commonly used to treat increased ICP; this study aimed to measure initial patient response to HTS and look for association with patient outcome. Patients >17 years old, admitted and requiring ICP monitoring between 2008 and 2010 at a large urban tertiary care facility were retrospectively enrolled. ⋯ In patients treated with HTS for intracranial hypertension, those who survived or had good neurological outcome, when compared to those who died or had poor outcomes, showed a significantly larger sustained decrease in ICP 2h after administration. This suggests that even early in a patient's treatment, treatment responsiveness is associated with mortality or poor functional outcome. While this work is preliminary, it suggests that early failure to obtain a sustainable response to hyperosmolar therapy may warrant greater treatment intensity or therapy escalation.

Association between concussion and mental health in former collegiate athletes.
The existing research on the association between concussion and mental health outcomes is largely limited to former professional athletes. This cross-sectional study estimated the association between recurrent concussion and depression, impulsivity, and aggression in former collegiate athletes. ⋯ Our study found an association between former concussion and greater risk of severe depression and higher levels of impulsivity and aggression among former collegiate athletes. Additional prospective studies better addressing causality and ascertaining valid lifetime concussion histories and medical histories are needed.
