There is limited research on the long-term effectiveness of epidural steroid injections (ESI) in older adults despite the high prevalence of back and leg pain in this age group. We tested the hypotheses that older adults undergoing ESI, compared to patients not receiving ESI: (1) have worse pain, disability and quality of life ('outcomes') pre-ESI, (2) have improved outcomes after ESI and (3) have improved outcomes due to a specific ESI effect. ⋯ In this large, two-year, prospective study in older adults with a new episode of low back pain, back pain, leg pain, disability and quality of life improved after epidural steroid injections; however, propensity-score matching revealed that the improvement was unlikely the result of a specific effect of the injections, indicating that epidural steroids are unlikely to provide long-term benefits in older adults with new episodes of back and leg pain.

Randomized Controlled Trial
Effects of transcranial direct current stimulation in pain and opioid consumption after spine surgery.
Transcranial direct current stimulation (tDCS) has shown promising results in alleviating different types of pain. The present study compares the efficacy of three sessions of anodal tDCS applied over primary motor area (M1) or the left dorsolateral prefrontal cortex (DLPFC) or sham on reducing pain and the total opioid consumption in postoperative spine surgery patients. ⋯ tDCS is a promising tool for alleviating pain in the field of postoperative spine surgery.

The current study aimed to identify patients presenting with acute pain who may be at risk for a complicated trajectory, via identifying clusters of early opioid prescribing patterns. ⋯ These clusters of acute opioid prescribing could facilitate the identification of patients who may benefit from enhanced pain care earlier in the pain trajectory and decrease future reliance on long-term opioid therapy.

Prelimbic medial prefrontal cortex (PL-mPFC) and nucleus accumbens core region (NAcc) play an important role in supporting several executive cognitive mechanisms, such as spatial working memory (WM). Recently, this circuit has been also associated with both sensory and affective components of pain. However, it is still unclear whether this circuit is endogenously engaged in neuropathic pain-related cognitive dysfunctions. ⋯ Selective optogenetic inhibition of prefrontal-striatal microcircuit reverses pain-related working memory deficits but has no significant impact on pain responses. Neuropathic pain underlies an increase of functional connectivity between the nucleus accumbens core area and the prelimbic medial prefrontal cortex mediated by theta-band activity.

Complex Regional Pain Syndrome (CRPS) is a rare but disabling pain condition. Accurate and timely education about CRPS is key to promote optimal clinical outcomes, but it is unclear what the content of that education should be. We aimed to determine the content that both people with CRPS and expert health care professionals (HCPs) reported as important. ⋯ This e-Delphi study identified the 48 core concepts that those with the lived experience of CRPS, and advanced practitioner health care professionals jointly rated as 'very important' to include in fundamental and accessible educational material.
