Association of Pre-operative Functional Disability with Chronic Postsurgical Pain: A Prospective Observational Study.
Chronic postsurgical pain negatively affects postoperative recovery. We aimed to assess the association between preoperative functional disability and chronic postsurgical pain. ⋯ Our study showed that in patients who undergo elective abdominal surgery, 12% with preoperative functional disability experience chronic postsurgical pain after 1 year. Preoperative functional disability is associated with chronic postsurgical pain, use of preoperative pain medications and acute postoperative pain. Patients with preoperative functional disability have higher pain numerical rating scale scores at any postoperative measurement point.

Meta AnalysisA Systematic Review and Meta-Analysis Examining the Impact of Age on Perioperative Inflammatory Biomarkers.
Dysregulation of immune responses to surgical stress in older patients and those with frailty may manifest as differences in inflammatory biomarkers. We conducted a systematic review and meta-analysis to examine differences in perioperative inflammatory biomarkers between older and younger patients, and between patients with and without frailty. ⋯ Our findings demonstrate a paucity of frailty-specific studies; however, the presence of age-associated differences in the perioperative inflammatory response is consistent with age-associated states of chronic systemic inflammation and immunosenescence. Additional studies assessing frailty-specific changes in the systemic biologic response to surgery may inform the development of targeted interventions.

Initial clinical studies have shown that the stimulation of the dorsal root ganglion (DRG) can significantly reduce chronic intractable pain. However, clinical data on long-term results and complications of these systems are limited. The aim of this prospective study is to report on a single center long-term follow-up of DRG stimulation for intractable chronic pain. ⋯ The findings were generally robust to imputation methods of missing data. Implantable pulse generators of 8 patients were explanted because of dissatisfaction with pain relief. In conclusion, DRG stimulation can provide effective pain relief and improved quality of life in patients suffering with neuropathic pain, although this study had a revision rate of 42% within the first 24 months, and 56% of IPGs that were replaced because of battery depletion had a shorter than expected battery life.

ReviewOpioid prescribing and use among cancer survivors: A mapping review of observational and intervention studies.
Recent years show a sharp increase in research on opioid use among cancer survivors, but evidence syntheses are lacking, leaving knowledge gaps. Corresponding research needs are unclear. ⋯ We found lack of consistency in the measurement of and terms used to describe similar opioid use outcomes, and a lack of interventional research targeting well-documented patterns of potentially nonrecommended, potentially avoidable, or potentially high-risk opioid prescribing or use.
