Clinical TrialA Nonliquid Crystal Display Screen Computer for Treatment of Photosensitivity and Computer Screen Intolerance in Post-Concussion Syndrome.
Liquid crystal display (LCD) screens refresh at a rate of 60 times per second, which can be perceived by concussed individuals who have photosensitivity, leading to computer intolerance. A non-LCD computer screen that refreshes at a much lower rate could relieve this photosensitivity and computer screen intolerance in patients with post-concussion syndrome (PCS). Twenty-nine patients with PCS, computer intolerance, and photosensitivity performed a reading task for a maximum of 30 min, with an LCD computer or a non-LCD device, and were given a comprehension test after completion of the reading task. ⋯ Subjective reports showed that the non-LCD experience was more favorable, and most patients stated they would recommend this device for other patients with PCS. This study is the first to show the clinical utility of non-LCD screen computers in the management of photosensitivity and computer screen intolerance in patients with PCS. The non-LCD screen computer has the potential to facilitate return-to-work or return-to-school in concussed individuals.

ReviewRehabilitative Training in Animal Models of Spinal Cord Injury.
Rehabilitative motor training is currently one of the most widely used approaches to promote moderate recovery following injuries of the central nervous system. Such training is generally applied in the clinical setting, whereas it is not standard in preclinical research. ⋯ Despite the importance of training and the many open questions regarding its mechanistic consequences, its use in preclinical animal models is rather limited. Here we review approaches, findings and challenges when training is applied in animal models of spinal cord injury, and we suggest recommendations to facilitate the integration of training using an appropriate study design, into pre-clinical studies.

Traumatic brain injury (TBI) is one of the leading causes of disability and mortality worldwide. The TBI pathogenesis can induce broad pathophysiological consequences and clinical outcomes attributed to the complexity of the brain. Thus, the diagnosis and prognosis are important issues for the management of mild, moderate, and severe forms of TBI. ⋯ Metabolic biomarkers can also be used for the prediction of outcome, monitoring treatment response, in the assessment of or prognosis of post-injury recovery, and potentially in the use of neuroplasticity procedures. Metabolomics can also enhance our understanding of the pathophysiological mechanisms of TBI, both in primary and secondary injury. Thus, this review presents the promising application of metabolomics for the assessment of TBI as a stand-alone platform or in association with proteomics in the clinical setting.

Randomized Controlled TrialCerebrospinal Fluid Biomarkers in Human Spinal Cord Injury from a Phase II Minocycline Trial.
Inflammatory changes after spinal cord injury (SCI) have been reported in animal models, but human studies are relatively limited. We examined cerebrospinal fluid (CSF) collected from subjects enrolled in a phase II placebo-controlled trial of minocycline for evidence of inflammatory and structural changes after acute human SCI. CSF was collected from 29 subjects every 6 h for 7 days and investigated for eight molecules. ⋯ Higher cumulative levels of IL-1β, MMP-9, and CXCL10 exhibited moderate, but significant, correlation with worse motor recovery at 12 months. Only HO-1 and NfH appeared to vary with minocycline treatment; HO-1 lacked a later peak compared to placebo-treated subjects while NfH did not manifest its early peak with treatment. These analyses of CSF biomarkers imply a pathophysiological role for particular molecules and suggest mechanistic targets for minocycline in human traumatic SCI.
