Meta Analysis
Analgesic efficacy of quadratus lumborum block in patients undergoing nephrectomy: A systematic review and meta-analysis.
To evaluate the analgesic efficacy of quadratus lumborum block (QLB) in adults undergoing nephrectomy. ⋯ Single-shot QLB provided a statistically significant but clinically small improvement in postoperative analgesia and recovery for patients undergoing nephrectomy. The QLB would be beneficial as part of multimodal analgesia. Future research might need to determine which approach of QLB is superior for postoperative analgesia after nephrectomy.

Meta Analysis
Size reduction of the right amygdala in chronic pain patients with emotional stress: A systematic review and meta-analysis.
The structural impact of chronic pain on amygdala in chronic pain (CP) patients remains unclear, although major depression and anxiety are known to be associated with its increase and decrease in size, respectively. This study aimed at examining the relationship between emotional stress and amygdala size in CP patients. The effects of mediating and moderating variables were also examined. ⋯ Besides, pain from a single body region was more likely to impact the amygdala size compared to diffuse pain (P = .02). Regression analysis revealed no significant association between continuous variables (age, gender, pain duration/intensity) and amygdala size. Our findings demonstrated that emotional stress was associated with a reduced right amygdala size in CP patients.

Patients within the safety net, defined as gap healthcare services for un- or under-insured persons, disproportionately suffer high impact chronic pain. The purpose of this review was to examine pain-related outcomes from multidisciplinary programs for patients with chronic pain within the safety net. A scoping review was conducted based on the Arksey and O'Malley framework coupled with the Preferred Reporting Items for Systematic reviews and Meta-Analyses-Scoping Review checklist. ⋯ Of the studies that employed quantitative measures, most demonstrated improvements in pain-related outcomes post-intervention, although not all statistically significant. Multidisciplinary pain programs may be of benefit to safety net patients with chronic pain. Further data collection is needed to determine the efficacy of these programs.
