This study aimed to investigate the perioperative analgesic effects of anterior quadratus lumborum block (QLB) for total laparoscopic hysterectomy (TLH). ⋯ Preoperative bilateral anterior QLB only reduced intraoperative opioid demand and postoperative abdominal visceral pain scores at 1 hour after surgery. Thus, the clinical significance of anterior QLB in TLH may be limited.

A single nerve block provides excellent analgesia in a short time, but rebound pain after the nerve block disappears has attracted researchers' attention. The aim of this study is to evaluate the effect of perineural dexamethasone on rebound pain after sciatic nerve block and femoral nerve block in patients undergoing unicompartmental knee arthroplasty (UKA). ⋯ Addition of dexmedetomidine to ropivacaine for UKA effectively prolonged the duration of nerve block and decreased c-reactive protein levels, but increased the incidence of rebound pain and rebound pain score, and had no beneficial effects on the postoperative analgesia.

Pain catastrophizing has been shown to be a prognostic indicator for pain severity and the co-occurrence of mental health conditions such as depression and post-traumatic stress disorder after whiplash injury. However, the pattern of available findings is limited in its implications for the possible "antecedent" or "causal" role of pain catastrophizing. The purpose of the present study was to examine the temporal relations between pain catastrophizing, pain severity, depressive symptoms, and post-traumatic stress symptoms (PTSS) in individuals receiving treatment for whiplash injury. ⋯ Findings support the view that pain catastrophizing might play a transdiagnostic role in the onset and maintenance of health and mental health conditions. The findings call for greater emphasis on the development of treatment techniques that target pain catastrophizing in intervention programs for whiplash injury.

Cannabis is increasingly being used for chronic pain management, but cannabis' effects remain poorly characterized in chronic nociplastic pain (NPP), which is posited to be caused by disturbances in nervous system pain processing. In this cross-sectional study (n=1213), we used the 2011 Fibromyalgia (FM) Survey Criteria as a surrogate measure for degree of NPP among individuals using medical cannabis for chronic pain. ⋯ This article presents evidence that individuals in higher NPP quartiles have higher analgesic intake, higher odds of substituting cannabis for medications, higher side effect burden, and lower therapeutic effect from cannabis. These seemingly contradictory findings may reflect higher symptom burden, polypharmacy at baseline, or that NPP may be challenging to treat with cannabis. Further research is necessary to further explain cannabinoid effects in NPP.

To determine the associations between neighborhood characteristics and chronic pain during childhood and adolescence in the United States, 2020-2021. ⋯ Disadvantageous neighborhood characteristics are associated with pediatric chronic pain prevalence. Future research should investigate the underlying mechanisms of this association and guide neighborhood interventions aimed at preventing and decreasing childhood chronic pain and its associated burdens.
