Clinical TrialReduction in bladder-related autonomic dysreflexia following onabotulinumtoxinA treatment in spinal cord injury.
Bladder-related events, including neurogenic detrusor overactivity, are the leading cause of autonomic dysreflexia in spinal cord injured individuals. Self-reported autonomic dysreflexia is reduced following onabotulinumtoxinA treatment for neurogenic detrusor overactivity; however, none of these trials have assessed autonomic dysreflexia events using the clinical cutoff of an increase in systolic blood pressure ≥20 mm Hg. This study used a prospective, open-labelled design from 2013 to 2014 to quantitatively assess the efficacy of one cycle 200 U intradetrusor-injected onabotulinumtoxinA (20 sites) on reducing the severity and frequency of bladder-related autonomic dysreflexia events and improving quality of life. ⋯ Frequency of 24 h bladder-related autonomic dysreflexia events was also decreased post-onabotulinumtoxinA (4 ± 2 events vs. 1 ± 1 events, p < 0.001). Autonomic dysreflexia and incontinence quality of life indices were also improved post-onabotulinumtoxinA (p < 0.05). Intradetrusor injections of onabotulinumtoxinA for the management of neurogenic detrusor overactivity in individuals with high level spinal cord injuries decreased the severity and frequency of bladder-related episodes of autonomic dysreflexia, and improved bladder function and quality of life.

Differential Histopathology and Behavioral Outcomes Eight Weeks After Rat Spinal Cord Injury by Contusion, Dislocation, and Distraction Mechanisms.
The objective of this study was to compare the long-term histological and behavioral outcomes after spinal cord injury (SCI) induced by one of three distinct biomechanical mechanisms: dislocation, contusion, and distraction. Thirty male Sprague-Dawley rats were randomized to incur a traumatic cervical SCI by one of these three clinically relevant mechanisms. The injured cervical spines were surgically stabilized, and motor function was assessed for the following 8 weeks. ⋯ After the dislocation injury mechanism, animals displayed no improvement in the grooming test, in contrast to the animals subjected to contusion or distraction injuries. These data indicate that different SCI mechanisms result in distinct patterns of histopathology and behavioral recovery. Understanding this heterogeneity may be important for the future development of therapeutic interventions that target specific neuropathology after SCI.

ReviewHealth-Related Quality of Life after Pediatric Mild TBI and Concussion: A Systematic Review.
Health-related quality of life (HRQOL) is an emerging method to quantify the consequences of pediatric mild traumatic brain injury (mTBI)/concussion in both clinical practice and research. However, to utilize HRQOL measurements to their full potential in the context of mTBI/concussion recovery, a better understanding of the typical course of HRQOL after these injuries is needed. The objective of this study was to summarize current knowledge on HRQOL after pediatric mTBI/concussion and identify areas in need of further research. ⋯ HRQOL represents an important outcome measure in mTBI/concussion clinical practice and research. The evidence shows that a small but important proportion of patients have diminished HRQOL up to a year or longer post-injury. Further study on this topic is warranted to determine the typical longitudinal progression of HRQOL after pediatric concussion.

Genome-Wide Changes in Peripheral Gene Expression following Sports-Related Concussion.
We conducted a prospective study to identify genome-wide changes in peripheral gene expression before and after sports-related concussion (SRC). A total of 253 collegiate contact athletes underwent collection of peripheral blood mononuclear cells (PBMCs) before the sport season (baseline). Sixteen athletes who subsequently developed an SRC, along with 16 non-concussed teammate controls, underwent repeat collection of PBMCs within 6 h of injury (acutely). ⋯ In conclusion, acute post-SRC transcriptional changes reflect regulation of the innate immune response and the transition to adaptive immunity. By 7 days, transcriptional activity is centered on regulating the hypothalamic-pituitary-adrenal axis. Future efforts to compare expressional changes in fully recovered athletes with those who do not recover from SRC could suggest putative targets for therapeutic intervention.

Core Outcomes and common Data Elements in Chronic Subdural Haematoma (CODE-CSDH): A systematic review of the literature focusing on baseline and peri-operative care data elements.
Chronic subdural hematoma (CSDH) is an increasingly common subtype of head injury, especially in the elderly population. The optimization of treatment strategies has been hampered by the collection of heterogeneous outcome measures and data elements, precluding cross-study comparisons. This study aimed to quantify the heterogeneity of data elements in the pre-operative, operative, and post-operative phases of care, and build the basis for the development of a set of common data elements (CDEs) for CSDH. ⋯ There was variable reporting of surgical technique and post-operative care; 32 studies (31.4%) made no mention of whether the operations were performed under general or local anesthetic. This study, a part of the Core Outcomes and Common Data Elements in CSDH (CODE-CSDH) project, confirms and quantifies the heterogeneity of data elements collected and reported in CSDH studies to date. It establishes the basis for the consensus-based development of a set of common data elements, facilitating robust cross-study comparisons and resulting improvements in patient outcomes.
