Resilience as an Independent Predictor of Bowel related Quality of Life following Spinal Cord Injury.
Bowel dysfunction remains a prominent priority in the rehabilitation of patients with spinal cord injuries (SCIs). However, our understanding of the factors that influence bowel-related quality of life (QoL) in this population remains limited. This study aimed to investigate the potential role of resilience, defined as an individual's capacity to cope with and adapt to adversity, as a predictor of bowel-related QoL among the patients with SCI. ⋯ Overall, this study elucidates the importance of resilience in shaping patients' perceptions of their bowel health within the SCI population. In addition to the more expected determinants of bowel-related QoL, such as the severity of bowel dysfunction, resilience emerged as a notable factor. Accordingly, integrating interventions that enhance resilience within bowel rehabilitation programs may yield improvements in patients' perceived bowel health beyond the benefits achievable through bowel function enhancement alone.

The inhibition of HMGB1 attenuates spinal cord edema by reducing the expression of Na+-K+-Cl- cotransporter-1 and Na+/H+ exchanger-1 in both astrocytes and endothelial cells after spinal cord injury in rats.
Sodium/water transport through Na+-K+-Cl- cotransporter-1 (NKCC1) and sodium/hydrogen exchanger-1 (NHE1) in both astrocytes and endothelial cells is critical to cytotoxic and ionic edema following spinal cord injury (SCI). High-mobility group box-1 (HMGB1) promotes spinal cord edema after SCI. Accordingly, we sought to identify both the role of HMGB1 and the mechanism of its effect on NKCC1 and NHE1 expression in astrocytes and endothelial cells as well as the role of the regulation of spinal cord edema after SCI. ⋯ The effects of HMGB1 on NKCC1 and NHE1 expression were mediated-at least in part-by activation of the Toll-like receptor 4 (TLR4)-Toll/interleukin-1 receptor domain-containing adapter inducing interferon-β (TRIF)-nuclear factor-kappa B (NF-κB) signaling pathway. The inhibition of NKCC1 or NHE1 decreased the spinal cord water content in rats following SCI, increased the Na+ concentration in the medium of cultured astrocytes after OGD/R, and reduced the astrocytic cell volume and AQP4 expression. These results imply that HMGB1 inhibition results in a reduction in NKCC1 and NHE1 expression in both astrocytes and microvascular endothelial cells and thus decreases spinal cord edema after SCI in rats and that these effects occur through the HMGB1-TLR4-TRIF-NF-κB signaling pathway.

Review Meta AnalysisRole of Frailty Status in Prediction of Clinical Outcomes of Traumatic Spinal Injury: A Systematic Review and Meta-Analysis.
Although many frailty tools have been used to predict traumatic spinal injury (TSI) outcomes, identifying predictors of outcomes after TSI in the aged population is difficult. Frailty, age, and TSI association are interesting topics of discussion in geriatric literature. However, the association between these variables are yet to be clearly elucidated. ⋯ However, no significant relationship was found between frailty and LoS (pooled OR: 3.02 [0.86; 10.60]). Heterogeneity was observed across multiple factors, including age, injury level, frailty assessment tool, and spinal cord injury characteristics. In conclusion, although there is limited data concerning using frailty scales to predict short-term outcomes after TSI, the results showed that frailty status may be a predictor of in-hospital mortality, AEs, and unfavorable discharge destination.

Randomized Controlled TrialCollaborative care versus usual care to improve quality of life, pain, depression, and physical activity in outpatients with spinal cord injury: The SCI-CARE randomized controlled clinical trial.
Our goal was to test the effectiveness of collaborative care (CC) versus usual care (UC) to improve treatment of pain, depression, physical inactivity, and quality of life in outpatients with spinal cord injury (SCI). We conducted a single blind parallel group randomized controlled trial. The setting was two outpatient SCI rehabilitation clinics within a large academic medical center. ⋯ The primary analysis, a mixed-effects linear regression adjusting for time since injury and sex, revealed a non-significant trend for greater improvement in quality of life in CC versus UC at 4 months (p = 0.083). Secondary analyses showed that those receiving CC reported significantly greater improvement in pain interference at 4- and 8-months and in depression at 4-months, but no significant effect on physical activity. We conclude that in an outpatient SCI care setting, CC is a promising model for delivering integrated medical and psychological care and improving management of common, chronic, disabling conditions such and pain and depression.

ReviewContrasting experimental rodent aftercare with human clinical treatment for cervical spinal cord injury: Bridging the translational "Valley of Death".
More than half of all spinal cord injuries (SCIs) occur at the cervical level and often lead to life-threatening breathing motor dysfunction. The C2 hemisection (C2Hx) and high cervical contusion mouse and rat models of SCI are widely utilized both to understand the pathological effects of SCI and to develop potential therapies. Despite rigorous research effort, pre-clinical therapeutics studied in those animal models of SCI sometimes fail when evaluated in the clinical setting. ⋯ In this review, we have summarized both the standard clinical interventions used to treat patients with cervical SCI and the various veterinary aftercare protocols used to care for rats and mice after experimentally induced C2Hx and high cervical contusion models of SCI. Through this analysis, we have identified areas of marked dissimilarity between clinical and veterinary protocols and suggest the modification of pre-clinical animal care particularly with respect to analgesia, anticoagulative measures, and stress ulcer prophylaxis. In our discussion, we intend to inspire consideration of potential changes to aftercare for animal subjects of experimental SCI that may help to bridge the translational "Valley of Death" and ultimately contribute more effectively to finding treatments capable of restoring independent breathing function to persons with cervical SCI.
