Although the challenges of living with chronic pain are widely documented within existing literature, to our knowledge, the acceptability of pain for people living with persistent pain, has not been fully explored. The current study aims to explore what 'acceptable pain' means to adults living with chronic non-cancer pain (CPCP). ⋯ Adults with CNCP have unique experiences of living with and managing their chronic pain. CNCP was found to affect biological, psychological, and social aspects of an individual's life. The acceptability of pain exists on a continuum where adjacent parts are not noticeably different from each other, but the extremes of the continuum appear very distinct. The acceptability of pain is determined by the different factors that influence an individuals' ability to function on a day-to-day basis as well as their quality of life. While acceptable pain and manageable pain represent distinct aspects of the pain experience, the relationship between them is complex and plays a crucial role in how individuals cope with and adapt to chronic pain.

Acute and chronic itch are prevalent and incapacitating, yet the neural mechanisms underlying both acute and chronic itch are just starting to be unraveled. Activated transcription factor 4 (ATF4) belongs to the ATF/CREB transcription factor family and primarily participates in the regulation of gene transcription. Our previous study has demonstrated that ATF4 is expressed in sensory neurons. ⋯ Furthermore, ATF4 interacts with the transient receptor potential cation channel subfamily V member 4 (TRPV4) and inhibits its function without altering the expression or membrane trafficking of TRPV4 in sensory neurons. In addition, interference with ATF4 increases the itch sensitivity in nonhuman primates and enhances TRPV4 currents in nonhuman primates DRG neurons; ATF4 and TRPV4 also co-expresses in human sensory neurons. Our data demonstrate that ATF4 controls pruritus by regulating TRPV4 signaling through a nontranscriptional mechanism and identifies a potential new strategy for the treatment of pathological pruritus.

Randomized Controlled Trial
The effects of virtual reality neuroscience-based therapy on clinical and neuroimaging outcomes in patients with chronic back pain: a randomized clinical trial.
Chronic pain remains poorly managed. The integration of immersive technologies (ie, virtual reality [VR]) with neuroscience-based principles may provide effective pain treatment by targeting cognitive and affective neural processes that maintain pain and therefore potentially changing neurobiological circuits associated with pain chronification and amplification. We tested the effectiveness of a novel VR neuroscience-based therapy (VRNT) to improve pain-related outcomes in n = 31 participants with chronic back pain, evaluated against usual care (waitlist control; n = 30) in a 2-arm randomized clinical trial ( NCT04468074). ⋯ Several secondary clinical outcomes were also improved by VRNT, including disability, quality of life, sleep, and fatigue. In addition, VRNT was associated with increases in dorsomedial prefrontal functional connectivity with the superior somatomotor, anterior prefrontal and visual cortices, and decreased white matter fractional anisotropy in the corpus callosum adjacent to the anterior cingulate, relative to the control condition. Thus, VRNT showed preliminary efficacy in significantly reducing pain and improving overall functioning, possibly through changes in somatosensory and prefrontal brain networks.

Even though a well-functioning primary care system is widely acknowledged as critical to population health, the number of primary care physicians (PCPs) practicing in the United States has steadily declined, and PCPs are in short supply. The reasons are multiple and include inadequate income relative to other specialties, excessive administrative demands on PCPs and the lack of respect given to primary care specialties during medical school and residency. Advanced practice nurses can augment the services of primary care physicians but cannot substitute for them. ⋯ The income gap between primary care and other specialties should be narrowed. The administrative load placed on PCPs, including cumbersome electronic medical records, must be lessened. Insurers, including Medicare and Medicaid, must provide the resources to allow primary care physicians to act as leaders of multidisciplinary teams.

Observational Study
Does celecoxib prescription for pain management impact post-tonsillectomy hemorrhage requiring surgery? A retrospective observational cohort study.
Adenotonsillectomy and tonsillectomy (referred to as tonsillectomy hereafter) are common pediatric surgeries. Postoperative complications include hemorrhage requiring surgery (2 to 3% of cases) and pain. Although nonsteroidal anti-inflammatory drugs are commonly administered for postsurgical pain, controversy exists regarding bleeding risk with cyclooxygenase-1 inhibition and associated platelet dysfunction. Preliminary evidence suggests selective cyclooxygenase-2 inhibitors, for example celecoxib, effectively manage pain without adverse events including bleeding. Given the paucity of data for routine celecoxib use after tonsillectomy, this study was designed to investigate the association between postoperative celecoxib prescription and post-tonsillectomy hemorrhage requiring surgery using chart-review data from the Children's Hospital of Eastern Ontario. ⋯ Celecoxib does not significantly increase the odds of post-tonsillectomy hemorrhage requiring surgery, after adjusting for covariates. This large pediatric cohort study of celecoxib administered after tonsillectomy provides compelling evidence for safety but requires confirmation with a multisite randomized controlled trial.
