ReviewSleep, 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). Although many questions remain unanswered, the preponderance of evidence suggests that sleep and circadian disorders can result from mTBI. Among those with mTBI, sleep disturbances and clinical sleep and circadian disorders contribute to the morbidity and long-term sequelae across domains of functional outcomes and quality of life. ⋯ Further, sleep and mTBI share neurophysiologic and neuroanatomic mechanisms that likely bear directly on success of rehabilitation following mTBI. For these reasons, focus on disturbed sleep as a modifiable treatment target has high likelihood of improving outcomes in mTBI. Here, we 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.

Meta AnalysisEfficacy of Oligodendrocyte Progenitor Cell Transplantation in Rat Models with Traumatic Thoracic Spinal Cord Injury: A Systematic Review and Meta-Analysis.
Spinal cord injury (SCI) is a devastating disease that results in severe motor, sensory, and autonomic dysfunction, for which there are currently no available treatments. Subsequent to the primary mechanical damage, progressive secondary damage further exacerbates the functional deficit. Demyelination may play an important role in the pathogenesis of SCI. ⋯ The percentage of myelinated axons increased significantly in the OPC group compared to that of the control group after OPC transplantation. Area measurements across groups revealed a significant reduction in cavity size in the OPC-treated groups compared to the control group. In conclusion, OPC transplantation provided considerable beneficial effects after traumatic SCI.
