The purpose of the current study was to investigate the influence of sleep on the relationship between pain and health care use (HCU) in youth with sickle cell disease (SCD). It was hypothesized that poor sleep would be related to higher HCU and would strengthen the relationship between high pain frequency and more HCU among youth with SCD. ⋯ Findings suggest that good sleep may serve as a protective factor for better matching pain to HCU. Results should be interpreted in the context of study limitations. Research is needed to investigate possible mechanisms linking sleep duration to HCU in response to pain and to ascertain if sleep patterns influence the relationship between pain and other functional outcomes in youth with SCD. Clinically, these findings support the need to acknowledge and address the role that sleep plays in responding to SCD pain in pediatric populations.

The objective of the review is to determine whether conditioned pain modulation (CPM) is impaired in adults with chronic low back pain (CLBP) when compared with pain-free individuals. ⋯ High-quality research is strongly recommended to determine the function of endogenous pain modulatory mechanisms in CLBP.

Deceptive and Nondeceptive Placebos to Reduce Pain: An Experimental Study in Healthy Individuals.
Recent research has shown that placebos can be effective even if they are openly prescribed to participants. Yet, it is unclear how such "open-label placebos" (OLPs) compare to deceptive placebo (DP) and what the mechanisms of actions are. In this study, we therefore compared 2 versions of OLP to DP and no treatment (NT). ⋯ The study provided evidence for traditional placebo analgesia on the basis of deception. For OLP, we found that OLP indeed increased pain tolerance; however, participants receiving OLP were reluctant to report any subjective analgesic effects. Combined with previous studies, the present findings suggest that the effects of OLP are weaker in healthy volunteers than in clinical samples.

Effects of Adding Oxycodone to Ropivacaine on Labor Analgesia: A Randomized Controlled Trial.
It's known that the addition of opiates to LA improves epidural analgesia in labour. This trial should have compared oxycodone to fentanyl.

Illusion-enhanced Virtual Reality Exercise for Neck Pain: A Replicated Single Case Series.
Body illusions have shown promise in treating some chronic pain conditions. We hypothesized that neck exercises performed in virtual reality (VR) with visual feedback of rotation amplified would reduce persistent neck pain. ⋯ Our hypothesis, that neck exercises performed in VR with visual feedback of rotation amplified, would reduce persistent neck pain was not supported. Possible explanations and future directions are discussed.
