The evidence for Internet-delivered pain management programs for chronic pain is growing, but there is little empirical understanding of how they effect change. Understanding mechanisms of clinical response to these programs could inform their effective development and delivery. ⋯ This study employed robust statistical techniques to assess the psychological mechanisms of an established internet-delivered pain management program. While clinical improvements (e.g. depression, anxiety, pain) were closely associated with improvements in psychological variables (e.g. pain self-efficacy and pain acceptance), these variables do not appear to be treatment mechanisms.

The indications for initiating long-term opioid treatment (L-TOT) for chronic non-cancer pain (CNCP) are often unclear and associated with problematic use. This study aimed at evaluating the efficacy of stabilizing opioid therapy followed by a sequential opioid tapering off program in CNCP patients. ⋯ This trial showed that sequential tapering off L-TOT in CNCP patients may be an unfeasible approach. However, improvements after opioid treatment stabilization were achieved and stable pain intensity in those tapered off may encourage the development of more refined programs.

Observational StudyEarly Risk and Resiliency Factors Predict Chronic Posttraumatic Stress Disorder in Caregivers of Patients Admitted to a Neuroscience ICU.
Informal caregivers-that is, close family and friends providing unpaid emotional or instrumental care-of patients admitted to ICUs are at risk for posttraumatic stress disorder. As a first step toward developing interventions to prevent posttraumatic stress disorder in ICU caregivers, we examined the predictive validity of psychosocial risk screening during admission for caregiver posttraumatic stress disorder at 3 and 6 months post hospitalization. ⋯ Screening neuroscience ICU caregivers for clinically significant posttraumatic stress disorder symptoms during admission is the single most important way to identify the majority of those likely to suffer from chronic posttraumatic stress disorder following discharge. Addressing early posttraumatic stress disorder symptoms and their psychosocial correlates during admission may help prevent chronic posttraumatic stress disorder in these at-risk caregivers.

Neural Invasion Spreads Macrophage-Related Allodynia via Neural Root in Pancreatic Cancer.
Neural invasion (N-inv) induces the neural damage and pain in pancreatic cancer (PCa). Benign nerve injury evokes allodynia through neuroinflammation in the neural root, which might be seen in PCa. Macrophages have the potential to release excitatory cytokines after nerve injury and so may play a role in the generation of chronic neuropathic pain. The aim of this study is to represent N-inv-induced allodynia in patients with PCa and to characterize allodynia-related neuroinflammation as macrophage accumulation on dorsal root ganglion (DRG) in the N-inv animal model (N-inv model). ⋯ The present study first showed that the N-inv-induced allodynia was spread in patients with PCa and in the N-inv model. Allodynia was related to the amount of macrophages at DRG in the N-inv model. The neuroinflammation may be a target for researching the N-inv-induced pain mechanism and developing novel analgesics.
