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 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.

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.

Several clinical trials have demonstrated the effectiveness of internet-delivered psychological-based pain management programs (PMPs). However, to date, no large studies have reported the outcomes of PMPs when delivered by specialist multidisciplinary pain services in routine care. The present study reports (n = 653) the outcomes of an internet-delivered PMP provided as routine care by a specialist Australian regional pain service over a 6-year period. ⋯ The current findings highlight the potential of internet-delivered PMPs as part of the services provided by specialist pain services, particularly those servicing large geographical regions and for patients unable to travel to clinics for face-to-face care. PERSPECTIVE: This study reports the outcomes of the routine delivery of an internet-delivered psychological PMP by a specialist pain service. The findings highlight the potential of this model of care when provided by specialist pain services, particularly for patients not unable to attend and not requiring intensive face-to-face care.

The epidemiology and prognosis of radiation-induced chronic pain, especially chronic neuropathic pain (CNP), are the understudied domain among head and neck cancer (HNC) survivors after radiotherapy (RT). This study aimed to estimate the prevalence of such chronic pain, and explore its correlations with mental health, sleep disorders, cognitive function, and quality of life (QOL) within these patients. This research encompassed HNC survivors post RT. ⋯ This study underscores the substantial prevalence of chronic pain, particularly CNP, and its potential impact on the mental health, sleep, and QOL among HNC survivors post RT. PERSPECTIVE: This study highlights the high prevalence of radiation-induced chronic pain and CNP, and their potential impacts on anxiety, depression, sleep, and QOL among the HNC survivors. Clinically, these findings have important implications for improving the care and outcomes of HNC survivors.
