Transcutaneous electrical nerve stimulation (TENS) is a nonpharmacological modality widely used to manage pain; however, its effectiveness for individuals with fibromyalgia (FM) has been questioned. In previous studies and systematic reviews, variables related to dose of TENS application have not been considered. The objectives of this meta-analysis were (1) to determine the effect of TENS on pain in individuals with FM and (2) determine the dose-dependent effect of TENS dose parameters on pain relief in individuals with FM. ⋯ The electrode placement was not significantly associated with any effect sizes. Thus, there is evidence that TENS can effectively reduce pain in individuals with FM when applied at high or at mixed frequencies, a high intensity, or in long-term interventions involving 10 or more sessions. This review protocol was registered at PROSPERO (CRD42021252113).

Randomized Controlled Trial
Best Practice Alerts Informed by Inpatient Opioid Intake to Reduce Opioid Prescribing After Surgery (PRIOR) - A Cluster Randomized Multiple Crossover Trial.
Overprescription of opioids after surgery remains common. Residual and unnecessarily prescribed opioids can provide a reservoir for nonmedical use. This study therefore tested the hypothesis that a decision-support tool embedded in electronic health records guides clinicians to prescribe fewer opioids at discharge after inpatient surgery. ⋯ A decision-support tool incorporated into electronic medical records did not reduce discharge opioid prescribing for postoperative patients in the context of vigorous opioid education and awareness efforts. Opioid prescribing alerts might yet be valuable in other contexts.(Anesthesiology 2023; 139:186-96).

Adaptations in somatosensory function characterize several chronic pain conditions, including nonspecific neck pain (NNP). Early signs of central sensitization (CS) contribute to pain chronification and poor treatment responses after conditions such as whiplash injury and low back pain. Despite this well-established association, the prevalence of CS in patients with acute NNP, and accordingly, the potential impact of this association, is still unclear. Therefore, this study aimed to investigate whether changes in somatosensory function occur during the acute phase of NNP. ⋯ Changes in somatosensory function occur already in acute NNP. Local mechanical hyperalgesia demonstrated peripheral sensitization, while enhanced pain facilitation, impaired conditioned pain modulation, and self-reported symptoms of CS suggest adaptations in pain processing already early in the stage of NNP.

Meta Analysis
Effect modifiers of virtual reality in pain management: a systematic review and meta-regression analysis.
There is a rapidly growing body of evidence for the application of virtual reality (VR) in pain management, however, with varying effectiveness. Little is known about patient-related and VR-related factors affecting efficacy of VR. A systematic review and meta-analysis was performed including 122 randomised controlled trials (9138 patients), reporting on subjectively reported pain scores comparing an immersive VR intervention to a non-VR control group. ⋯ Heterogeneity was considerable for all meta-analyses, and risk of bias was moderate to high in most included studies. Studies on mechanisms behind VR analgesia in younger patients and patients reporting moderate to severe pain are recommended to confirm our hypotheses while taking into account risk of bias and the comparator. Optimal application of VR using treatment modules for long-term pain conditions are an important issue for future research.

To verify an intraoperative adverse event (iAE) classification (ClassIntra grade) to evaluate quality control and to predict the prognostic performance of laparoscopic radical surgery for gastric cancer. ⋯ The ClassIntra grade is an effective prognostic and surgical quality control index for laparoscopic radical surgery for gastric cancer; therefore, it could be included in routine hospital care and surgical quality control.
