Exploring the emotional impact of pain on children and adolescents: a poetic meta-ethnography.
EXPLORING THE EMOTIONAL IMPACT OF PAIN ON CHILDREN AND ADOLESCENTS: A META-ETHNOGRAPHIC POETIC SYNTHESIS: Pain in early life can go unreported and untreated. We use poems to portray findings from a systematic review of qualitative research. The overall aim of the review was to distil essential experiences across pain conditions and contexts. ⋯ PERSPECTIVE: The voices of young people in pain are not always heard. This article presents themes, in poetic form, from a synthesis of 189 qualitative studies. Science and art are integral to leaps in understanding and inclusive arts-based research methods have the potential to underpin compassionate pain care for young people.

Untreated or undertreated pain is well established as a significant problem, but unidentified pain is a distinct construct that still needs to be clearly modeled or fully described. This paper aims to develop a conceptual model of unidentified pain in humans with the goal of future development of an unidentified pain risk tool. A multi-phase process was employed consisting sequentially of 1) brainstorming followed by consensus building, 2) peer-review and publication of an integrative theoretical review protocol for "unidentified pain," 3) conduct of the integrative review, and 4) a repeated brainstorming session to identify areas of risk for unidentified pain to produce a conceptual model. ⋯ The development of this conceptual model will be used for future development and psychometric testing of a tool to recognize the risk for unidentified pain in humans. PERSPECTIVE: This focus article describes the development a conceptual model for the concept of unidentified pain in humans. This pain may occur in individuals who experience one or more interactive and cumulative hazards: cognition/communication problems, being alone, absence of a surrogate/proxy report, or presence of known painful conditions or treatments.

The limited understanding of the mechanisms underlying human discogenic low back pain (DLBP) has hampered the development of effective treatments. While there is much research on disc degeneration, the association between degeneration and pain is weak. Therefore, there is an urgent need to identify pain-inducing molecular mechanism to facilitate the development of mechanism-specific therapeutics. ⋯ Major weaknesses in the current literature are the focus on degeneration without pain phenotyping, and lack of association of molecular findings with pain outcomes. PERSPECTIVE: This scoping review identified TNF-α, NF-κB signaling, and ROS-induced pro-inflammation as relevant mechanisms of human discogenic low back pain. Major weaknesses in the current literature are the focus on degeneration without pain phenotyping, and lack of association of molecular findings with pain outcomes.

Review
Persistent pain, long-term opioids, and restoring trust in the patient-clinician relationship.
The erosion of trust in the patient-clinician relationship is an underappreciated, and vital, component of the prescription opioid crisis. Drawing from lived experience of patients and clinicians, and a narrative evidence review, this report discusses how opioid use for persistent pain can impact the patient-clinician relationship from the vantage points of the patient and the family physician. For patients, the stress of dealing with persistent pain, misalignment with clinicians regarding goals of care, experiences of disrespect and stigma, fear of abrupt tapers, and frustration with a fragmented health system, all combine to breed a lack of trust. ⋯ To support implementation of evidence-based guidelines and achieve public health goals of safer prescribing and reducing harm from prescription opioids, we recommend steps health systems and clinicians can take to rebuild trust in the patient-clinician relationship, enable patient-centered pain care, and embed patient perspectives into opioid safety processes. PERSPECTIVE: Erosion of patient-clinician trust is a barrier to implementing evidence-based guidelines that aim to improve opioid safety. This paper explores lived patient and clinician experiences and recommends steps for health systems and clinicians to rebuild this trust as a strategy to actualize the benefits of adherence to these guidelines.

The role of the complement system in pain syndromes has garnered attention on the back of preclinical and clinical evidence supporting its potential as a target for new analgesic pharmacotherapies. Of the components that make up the complement system, component 5a (C5a) and component 3a (C3a) are most strongly and consistently associated with pain. Receptors for C5a are widely found in immune resident cells (microglia, astrocytes, sensory neuron-associated macrophages (sNAMs)) in the central nervous system (CNS) as well as hematogenous immune cells (mast cells, macrophages, T-lymphocytes, etc.). ⋯ A perspective on the optimal application of different C5a inhibitors for different types (e.g., neuropathic, post-surgical and chemotherapy-induced pain, osteoarthritis pain) and stages (e.g., acute, subacute, chronic) of pain is also provided to help guide future clinical trials. PERSPECTIVE: This review highlights the role and mechanisms of complement components and their receptors in physiological and pathological pain. The potential of complement-targeted therapeutics for the treatment of chronic pain is also explored with a focus on C5a inhibitors to help guide future clinical trials.
