Neuropathic pain causes both sensory and emotional maladaptation. Preclinical animal studies of neuropathic pain-induced negative affect could result in novel insights into the mechanisms of chronic pain. Modeling pain-induced negative affect, however, is variable across research groups and conditions. ⋯ Our data demonstrate that despite equivalent task learning, spared nerve injury mice are less motivated to work for a sugar pellet than sham controls. Furthermore, when we normalized behavioral responses across all the behavioral assays we tested, we found that a combined normalized behavioral score is predictive of injury state and significantly correlates with mechanical thresholds. Together, these results suggest that homecage-based operant behaviors provide a useful platform for modeling nerve injury-induced negative affect and that valuable pain-related information can arise from agglomerative data analyses across behavioral assays-even when individual inferential statistics do not demonstrate significant mean differences.

Pain is a major socio-psychological problem worldwide. Chronic pain has a negative effect on areas of psychological functioning such as depression, anxiety, and perceived stress. ⋯ In general, the results revealed that experiential avoidance can mediate the relationship among pain, pain anxiety, and pain disability as a maladaptive regulation strategy. The results obtained from this study seem to introduce experiential avoidance as a vulnerability factor effectively.

Older adults undergoing total knee arthroplasty may develop chronic pain without effective postoperative pain management. Increasing nurses' knowledge, changing their attitudes, and developing their pain management self-efficacy could improve the effectiveness of pain management. ⋯ An online learning program improves nurses' understanding and ability to manage pain in older adults undergoing total knee arthroplasty. This was therefore an effective learning method.

Undertreated pediatric postsurgical pain negatively affects health-related quality of life (HRQOL) and functioning and may lead to chronic postsurgical pain (CPSP). Predictors of recovery have been identified but more research is needed, particularly regarding resilience, social factors, and long-term effects. The aim of the present study was to investigate child and parent risk and resilience factors as predictors of long-term postsurgical recovery for adolescents. ⋯ The study identified pain and adolescent pain catastrophizing as risk factors, and adolescent and parental psychological flexibility and adolescent pain acceptance as resilience factors, for long-term recovery in youths undergoing spinal fusion. Postsurgical pain management targeting these factors may therefore promote recovery for these adolescents.

Assessment of fatty infiltration of the hamstring muscles in chronic proximal hamstring ruptures and effect on clinical outcomes after surgical repair: a novel application of the Goutallier classification.
Increased time to surgery has been previously associated with poorer clinical outcomes after surgical treatment of proximal hamstring ruptures, though the etiology remains unclear. The purpose of this study was to evaluate whether degree of muscle atrophy, as assessed using the Goutallier classification system, is associated with worse outcomes following surgical treatment of chronic proximal hamstring ruptures. ⋯ The degree of atrophy was not found to be an independent predictor of clinical outcomes following repair of chronic proximal hamstring ruptures. Increasing age was significantly predictive of increased atrophy and poorer patient-reported outcomes.
